On HPFS it is slooooooooooooooow. eCom 2.0 will be bootable JFS so you may want to wait until then.

The other eComStation guy. Mon, 05 Feb 2007 22:09:00 GMT [email protected] (ronaldst) Comments Because they want to :) http://www.osnews.com/thread?209460 http://www.osnews.com/thread?209460 JonInAtlanta,
There are many OSes out there with minimal userbases that get updates all the time. In the case of Serenity Systems, they have paying customers who want this functionality. The continued development of their OS allows them to fund this development.
There are many people out there who run Operating Systems with what would be considered a minimal user-base, and there are too many of those operating systems to mention in one single posting.
There are also unique reasons for each person wanting to do what they want. It's called Free Will or the pursuit of knowledge. These people do what they want because they want to do it, and may learn something from the process.
While you or I may not agree with the choices that some people make for a choice of operating environment to use, or what software to port to it, its not up to us to criticize them, or their reasons, for doing what they do.
Otherwise, this is an accomplishment that's quite interesting, as this came out long before a native OpenOffice for OS X ;) .

RE: Whats the point? http://www.osnews.com/thread?209462 http://www.osnews.com/thread?209462 They actually have a pretty good installed user base. They have picked up a lot of OS2 customers that IBM no longer supports.
For a big company it's no money, but for a small company with a small staff I am sure they are making a few hundred thousand dollars a year.
I would like to have that coming in. More money then me and my staff make. :-(
I actually bet they bring in more money then companies like Ununtu, Linspire and others who are putting in a LOT more money, time and manpower.

RE: Whats the point? http://www.osnews.com/thread?209464 http://www.osnews.com/thread?209464 If it wasn't worth their while, I suspect they wouldn't be doing it.
As it is, though, why not? I think it's nice to see at least one solid alternative OS which is not derived from UNIX continue to live.

Standard Answer http://www.osnews.com/thread?209472 http://www.osnews.com/thread?209472 Why bother to put the time, money, and manpower into a build for an OS with a minimal user-base?
Why [insert whatever you want] for a OS like [insert small-market OS]
Answer: It's OSNews.com dude! People do stuff like this becauses they like it, love it, want to do it, feel compelled, or whatever. Some make money, some don't. If that rattles you, then just head on over to MSN and have fun! I hear they have Pics of Paris Hilton!

Too bad... http://www.osnews.com/thread?209473 http://www.osnews.com/thread?209473 Too bad it's so expensive... Warp was awesome on my Pentium 100MHz back 10 years ago... No way I'll pay $189 for an academic version now though.

US$79 isn't too bad. Tue, 06 Feb 2007 01:00:00 GMT [email protected] (rcsteiner) Comments Innotek is evil... http://www.osnews.com/thread?209507 http://www.osnews.com/thread?209507 They actually charge for their builds of a a free product and ruthlessly anybody who might even THINK of providing a free build. Various people tried this with builds GIMP for Windows, but it never really had an effect as the official GIMP webpage makes no mention of this travesty and provides it's own builds for free as is good and natural. Tue, 06 Feb 2007 01:04:00 GMT [email protected] (madcrow) Comments RE: Innotek is evil... http://www.osnews.com/thread?209524 http://www.osnews.com/thread?209524 Not so evil. Innotek wrote a library that allows OS/2 (eCS, whatever) to simulate many of the library calls of another OS. They integrated OpenOffice with this library (and probably made significant alterations to the library). This is what they're charing for. I'm happy to pay it.
How do they go after others that provide a free build? Are you mixing them up with GoldenCode?

RE[2]: Whats the point? http://www.osnews.com/thread?209526 http://www.osnews.com/thread?209526 Unless you're a totally pompous ass Thom, it's a legitimate question Thom. For a company to put resources into a product that has little to no chance of making a profit is BAD BUSINESS Thom (ask Yellow Tab).
Hobby OSs' are fine, no argument, but they aren't a smart business move, Thom.

RE[3]: Whats the point? http://www.osnews.com/thread?209566 http://www.osnews.com/thread?209566 Because there are still companies out there using OS/2. Isn't this obvious to you? O_o
There are a lot companies using OS/2 in the embedded field.

Hobby OSs' are fine, no argument, but they aren't a smart business move, Thom.
First of all, what concern is it of yours if these businesses make any money or not? (Serenity Systems obviously does make money by the way.)
Secondly, have you ever used eComStation? It actually is a pretty decent OS. Not something I could use everyday, but that's more because I'm a *NIX-head. Serenity Systems have done a lot of great things for the OS/2 community, and yes there are a lot of businesses still running mission critical code on OS/2 or eComStation today. It is difficult and probably not cost effective to port legacy applications off of this platform because the OS/2 APIs are very different from the rest of the OSes out there today. Additionally, in the business world, a lot of people (rightly so) subscribe to the mantra "if it ain't broke, don't fix it". By porting code that has worked flawlessly for a decade or more, you have a HUGE potential for introducing subtle bugs. This is not acceptable for many applications. Additionally, a lot of in-house software is poorly documented and difficult to work with and understand, especially if the person who originally wrote that code has gone on to greener pastures. In these cases, legacy binary compatibility is a must.
Thirdly, if you see something posted on this site as useless, do the rest of us a favor and ignore it. Don't tell us it's useless, just say to yourself, wow, that's useless, and move on to a story that you can contribute positive discussion to.
If you want to read stories with this formula:
if(topic=="Linux"||topic=="Windows"||topic=="Mac") then post()
...then I suggest you take a look at Slashdot.org
Most of the rest of us like reading about obscure OSes.

RE: Innotek is evil... http://www.osnews.com/thread?209611 http://www.osnews.com/thread?209611 Innotek is not evil: they have all the right to make you pay for the runtime library that allows OS/2-eCS to run Win32 binaries. It's something like CrossOver on Linux.
And they are NOT preventing anybody from providing a free build... there were in fact a few dudes running OpenOffice on the free Odin runtime (Odin=wine, Innotek=CrossOver), but it was not working as well.
Anyway, the build we're talking about here is a NATIVE build, and AFAIK it's not done by Innotek.

RE[3]: Whats the point? http://www.osnews.com/thread?209612 http://www.osnews.com/thread?209612 Jon, not only they are making profit, but they are making it even BEFORE releasing the final port: this port was realized because of a lot of people was interested. They issued a "support agreement", where people would buy the final product (and have right to all the betas and to the previous 1.1.5 release) for a reduced price, but paid BEFORE the start of the actual development.
...and BTW, calling OS/2 a "hobby OS" is frankly ridiculous.

RE[3]: Whats the point? http://www.osnews.com/thread?209687 http://www.osnews.com/thread?209687 The fact that you're calling an OS from IBM a "hobby OS" is rather interesting. Are you that out of touch with OS/2's rather lengthy history in business?

He hasn't been active on the eCS mailing lists for quite a while (since 2001?). Tue, 06 Feb 2007 17:08:00 GMT [email protected] (rcsteiner) Comments RE: Whats the point? http://www.osnews.com/thread?210155 http://www.osnews.com/thread?210155 Why bother to put time into complaining about something you know nothing about? What do you get out of it? Does it make you feel better? Do you feel more like a man?
Do you often take time to complain about every other operating system that isn't microsoft based? If you do then you already understand your own question and should apply it to what you do.
I defend your right to whine and complain about everything, but I will tell you most people have given that up by the time they reach 8 years old. How old are you?

Ironies in origins http://www.osnews.com/thread?210163 http://www.osnews.com/thread?210163 Open Office arose from Sun's release of code--I'm showing I don't know the legally and technically correct expression--for an office productivity suite, Sun Office, which Sun still develops and distributes. Which came from? Inhouse work in porting Star Office from and by a German company, Star, which Sun had purchased several years earlier. And for what OS had Star created its most extensive --(or only?--version of Star Office, (including a browser)? The predecessor of ecomstation, IBM's OS/2.

Good software on good hardware. Instead of a cheaply made DELL. Get a machine that will last. eComStation is more stable than any windows yet easier than Linux.

One of the only vendors that sells desktop computers with ECC memory too.
Why buy DELL junk when there are good suppliers you can buy from.

What's the point ? http://www.osnews.com/thread?211639 http://www.osnews.com/thread?211639 What's the point ?, someone asked. (And -- by implication -- not just in developing for the OS, but in anyone bothering to run it.) Oh, I dunno, maybe the **near total immunity** from tons of malware and ongoing, ubiquitous exploit holes out there in the Redmond products ?! It's not simply a matter of stability, because W2K and XP finally reached a point of being much better than what MS had done before. It will likely take Vista a good couple years to get to that point.
But big market share always makes you a target worth going after, so it becomes a big plus to be little known and essentially invisible. This is particularly the case in regard to mainstream business apps, such as are covered by Open Office, where you only need to be able to work compatibly with the prevalent file formats. For other apps, such as in some multi-media areas, I'm afraid you'll just have to keep strapping that gigantic neon bullseye onto your back ! Or head on over to the 'Nix.Edited 2007-02-11 21:44

Nokia Lumia 920 vs Samsung Galaxy S3 vs HTC One X
September 8th, 2012
The mobile world has changed a lot since Nokia last put out a phone that truly wowed large amounts of people. Its tie in with Microsoft spawned some half decent handsets but despite Nokia’s best efforts, the world was never truly set alight.
Cue Nokia World 2012 and the announcement of the Nokia Lumia 920. Make no mistake, this is more than a big deal for both Nokia and Microsoft, with both having a lot riding on their respective contributions. Many see it as Nokia’s big throw of the dice: make Windows Phone 8 into a top OS and the rewards are huge… fail, and things look ropey for the Finns.

HTML5 Mastery: Encoding
by

This post is part of a series called HTML5 Mastery Class.

HTML5 Mastery: Fragments
HTML5 Mastery
Encoding is just one of those things that need to be done right. If done wrong, everything seems to be broken and nothing works. If done right, no one will notice. This makes dealing with encoding so annoying.
Nevertheless, we are quite lucky and most of the things are already really well-prepared. We only need to ensure that our documents are saved (and transmitted) with the right encoding. The right encoding is the one we specify. It could be anything, as long as it contains all characters we need, and as long as we stay consistent.
There are three important text encoding rules for HTML:
1. Load the content with the right encoding.
2. Transmit the content with the same encoding.
3. Ensure that the client reads the content with the specified encoding.
In this article we will have a closer look at all three rules in more detail, especially the second and the third. In the end we will also look at form encoding, which has nothing to do with text encoding directly, but does indirectly. We will see why there is some connection.
Choosing the Right Encoding
Either we know directly that our content should be delivered in some exotic encoding or we should just pick UTF-8. There are many reasons why we would want to use UTF-8. It is not a great format for storing characters in memory, but it is just wonderful as a basis for data exchange and content transmission. It is basically a no-brainer. Nevertheless, one of the more common mistakes is to save files without proper encoding. As there is no text without encoding, we should choose the encoding carefully.
Users of Sublime Text and most other text editors have probably never faced a problem with wrong encoding, since these editors save in UTF-8 by default. There are editors, mostly for the Windows platform, which a use different default format, e.g., Windows-1252.
Even in Sublime Text it is one of the more standard operations to change the encoding of the file. In the File menu we select Save with Encoding and select the one we want. That’s it!
Saving Text Encoding Sublime Text
In principle every more advanced editor should have such options. Sometimes they are contained in an advanced save menu. For instance, the editor for Microsoft’s Visual Studio triggers a special dialog after clicking Advanced Save Options… in the File menu.
Visual Studio Advanced Save
We should make sure to use the right encoding. This will use the corresponding bytes for our content. UTF-8 has the major advantage of only requiring a single byte if we do not use a special character. At most 4 bytes per character are consumed. This is dynamic and makes UTF-8 an ideal format for text storage and transmission. The caveat is, however, that UTF-8 is not the best format for using strings from memory.
Controlling the Transmission
The HTTP protocol transmits data as plain text. Even if we decide to encode the transmitted content as GZip or if we use HTTPS, which encrypts the content, the underlying content is still just plain text. We’ve already learned that there is no such thing as just plain text. We always need to associate the content with some encoding to get a text representation.
An HTTP message is split in two parts. The upper part is called the headers. Separated by an empty line is the lower part: the body.
There are always at least two HTTP messages: a request and its associated response. Both types of messages share this structure. The body of a response is the content we want to transmit. The body of a request is only of interest for form submission, which we’ll care about later. If we want to provide some information on the encoding of the content, we have to supply some information in the header.
The following header tells the receiving side that the body contains a special text format called HTML, using the UTF-8 character set.
There is also the Content-Encoding header. We can easily confuse the content encoding with the actual text encoding of the content. The former is used to specify encoding of the whole package, e.g. GZip, while the latter is used as an initial setting for, e.g., parsing the provided content.
If we care about the correctness of this step we have to make sure that our web server sends the correct header. Most web frameworks offer such an ability. In PHP we could write:
In Node.js we may want to use the following, where res is the variable representing the request:
The transmitted header will set the text scanner of the HTML input to the provided setting. In the case of the previous example we use UTF-8. But wait: Initial setting! There are many ways to override this. If the actual content is not UTF-8, the scanner may recognize this and change the setting. Such a change may be triggered by Byte-Order-Mark (known as BOM) detection or by finding encoding-specific patterns in the content. In contrast, the former looks for artificially prepended patterns.
Finally, the encoding may change due to our HTML code. This can only be changed once.
Fixing the Encoding
Once the DOM constructor hits a meta tag, it will look for a charset declaration. If one is found, the character set will be extracted. If we can extract it successfully and if the encoding is valid, we set the new encoding for scanning further characters. At this point the encoding will be frozen, and no further changes are possible.
There is just one caveat. To check if the previous scanning was alright, we need to compare the characters that have already been scanned with the characters that would have been scanned. Hence we need to see if changing the encoding earlier would have made some difference. If we find a difference, we need to restart the whole parsing procedure. Otherwise the whole DOM structure may be wrong up to this point.
As a consequence we’ve already learned two lessons:
1. Place the <meta charset="utf-8"> (or some other encoding) tag as soon as possible.
2. Only use ASCII characters before specifying the charset attribute in HTML.
Finally, a good starter for a boilerplate looks as follows. As we learned in the previous article, we can omit the head and body tags. The snippet does two things right: It uses the correct document type, and it selects the character set as soon as possible.
The only remaining question is: What happens if I forget one of these three steps? Well, the first and third steps are the most important ones. The transmission is actually not that bad. If no initial encoding is given from the HTTP headers, the browser will select the initial encoding based on the user’s locale. With a German locale we get Windows-1252. This is actually the default for most countries. Some countries, like Poland or Hungary, select Latin2, also known as iso-8859-2.
In principle we do not have to worry about this initial encoding if we followed the best practices described earlier. ASCII is a subset of Unicode, and most of the listed encodings are actually just ASCII extensions to satisfy the specific needs of one or more countries. If we only use basic ASCII characters until the character set is specified, we should be fine.
Much more severe is a conflict between the stored / read or generated data, which is delivered to the client, and the statement in the meta tag. If something went wrong we may see renderings like the following. This is not a pleasant user experience.
Encoding Problem
Coming back to determining the right encoding, there are many reasons why UTF-8 would be the best choice. Any other encoding should at least be sufficient for the characters we want to display. However, if we provide form input fields, we may be in trouble. At this point we do not control the characters that are used any more. Users are allowed to input anything here. Let’s see how we can control the encoding for form input.
Submitting Forms
A form is submitted with a certain encoding type, which is not the same as the encoding type of a server’s response, e.g. GZip. The form’s encoding type determines how the form is serialized before sending it to the server. It is particularly useful in conjunction with the HTTP verb.
Ordinary form submissions use POST as HTTP verb, but GET, PUT and DELETE are also common. Only POST and PUT are supposed to use the body for content transmission in the request. The browser will construct the content with respect to the choice of the enctype attribute of the <form> element, specifying the encoding type. The encoding type is transported by setting the Content-Type header in the HTTP request.
There are three well-established encoding types:
1. URL encoded (default value, explicitly application/x-www-form-urlencoded)
2. Plain text (text/plain)
3. Multipart (multipart/form-data)
The first and the second are quite similar, but they have subtle (and very important) differences. The third variant is the most powerful method. It even allows the transporting of arbitrary files as attachments.
The key difference between the first two types is that URL encoded form transmission percent-encodes all names and values, which is not done by plain text. The percent-encoding guarantees that the receiving side can distinguish between names and values. This guarantee does not exist with plain text form submission. The third variant uses a boundary string to separate the entries, which is unique by construction.
Let’s visualize the differences by submitting a simple form. The form contains the following code:
Submitting the form without specifying any encoding type transmits the following body:
The URL encoding transforms the white-space characters to plus signs. Existing plus signs, like all “special” characters, are transformed by the percent-encoding rules. This especially applies to new lines, originally represented by \r\n, which are now displayed as %0D%0A.
Let’s see what the outcome for plain text encoding looks like.
The pairs are split by new lines. This is especially problematic for multi-line content and may lead to incorrect representations.
In a way the multipart encoding combines the advantages of plain text submission with a defined boundary, which essentially solves the problems of the plain text encoding. The only drawback is the increased content length.
The last two form encoding methods also displayed special characters exactly as we’ve entered them. Form transmission primarily uses the accept-charset attribute of the corresponding `</form>
` element. If no such attribute is given, the encoding of the page is used. Again, setting the correct encoding is important. In the future we will see a fourth encoding type, called `application/json`. As the name suggests, it will pack the form content into a JSON string. ## Conclusion Choosing the right encoding can be as easy as just picking UTF-8. Typical problems can be avoided by using the same encoding consistently. Declaring the encoding during transport is certainly useful, although not required, especially if we follow best practices for placing a `` element with the `charset` attribute. Form submission is a process that relies on the right encoding choice—not only for the text, but for the submission itself. In general we can always choose `multipart/form-data` as `enctype`, even though the default encoding type might be better (smaller) in most scenarios. In production we should never use `text/plain`. ## References * [UTF-8: The Secret of Character Encoding](https://htmlpurifier.org/docs/enduser-utf8.html) * [W3C Specification: Form Submission](http://www.w3.org/TR/html5/forms.html#attr-fs-enctype) * [W3C Specification: Encoding](http://www.w3.org/TR/encoding/) * [W3C Specification: Initial Encoding Determination](http://www.w3.org/TR/html51/syntax.html#the-input-byte-stream) * [StackOverflow: What is the boundary in multipart/form-data?](https://stackoverflow.com/questions/3508338/what-is-the-boundary-in-multipart-form-data)

You will be creating a World that consists of ants and doodlebugs. Each time you click the board each bug will do some of the following: move, bread, eat, and starve.
Ants will function in a certain way, and doodlebugs in another.
This assignment is based on Absolute Java.
900_Bug Simulation 1.png
Bug Rules
Ants
Move
1. Every time step the ant will attempt to move.
2. Pick a random direction using a random generator (up, right, down, or left).
3. If the space is on the grid, and not occupied then the ant will move there.
Breed
1. If an ant survives 3 time steps he will attempt to breed.
2. He breeds by creating a new ant in a space adjacent to himself.
3. If there is no empty space adjacent to himself to breed then he will not do so.
4. He will then wait 3 more time steps until tries to breed again.
Doodlebugs
Move
1. Every time step the doodlebug will move.
2. First he will check out each direction. If there is an ant in an adjacent space he will move there (consequently taking up the ants space and eating him!)
3. If there was no ant in an adjacent space he will move just like ants do.
4. Note: doodlebugs can't eat other doodlebugs
Breed
1. If a doodlebug survives 8 time steps he will attempt to breed.
2. He breeds in the same manner as an ant.
Starve
1. If an ant has not eaten an ant within the last 3 time steps, then at the end of the last time step he will die of starvation. You will remove him from the grid.
UML
Ants and Doodlebugs will extend from a generic Organism.
Create a UML diagram for the Organism, Ant and Doodlebug. This diagram may change as you develop your design, but having a basic flow will greatly help in the implementation.
Provided Files
1. World.java
2. Organism.java
3. Ant.java
4. Doodlebug.java
5. ant.png
6. doodlebug.png
Word
Methods you will use in your classes. Don't modify this class.
public Organism getAt(int x, int y)
1. Returns the Organism at the x, y position in the grid.
2. If there is no organism it returns null
public void setAt(int x, int y, Organism bug)
1. Sets the entry at the x, y position in the grid to the specified organism
public boolean pointInGrid(int x, int y)
1. Returns true if the point x, y is in the grid and false if it goes beyond the grid space (e.g. if x = -1 that is not in the grid)
Images
1. Put the two images in an images folder within your src
What you need to edit
1. Organism.java
2. Ant.java
3. Doodlebug.java
Organims
Here are the methods that the World calls on the Organisms. I assume you will want to make more methods, such as move...
Organism(World world, int x, int y)
1. Creates a new Organism
2. The coordinates in the grid (X and Y) are required so you can pick a new location relative to its current to move to, and breed at.
3. The World is required so you can call methods like getAt(x, y), setAt(x, y), and pointInGrid(x, y) on it.
public abstract String toString()
1. This method is written for you
2. Returns the string representation of the organism ("ant", "doodlebug"). Used by the World to determine which type of organism it is.
public void resetSimulation()
1. This method has been written for you
2. You will need to keep track of weather the organism has simulated this time step or not in an attribute of the class. This is important as it stops an organism from moving to a new place in the grid and then simulating again.
public boolean simulate()
1. This will set the attribute that keeps track of weather it has simulated to true. This method returns true if it simulates, and false if it doesn't (has already simulated)
2. If the organism was created this time step don't do the rest
3. Call move, then breed, then starve (only for doodlebugs).
4. You will then increment a time step counter
Ant and DoodleBug
1. I want you to figure out what goes here

<title>KeePassX Quick-start Guide</title>
</head>

<a name="top" />
<h1>KeePassX Quick-start Guide</h1>
<p>
This guide helps you to manage your
passwords efficiently and securely with KeePassX.
</p>
<a name="startup" />
<h2>Starting up</h2>
<p>
After starting KeePassX for the first time, you
are presented with the main window with
no open database file. If you have used KeePassX
(or KeePass Classic on Windows) previously, you can
open your existing database. Otherwise we begin
with creating a new password database.
</p>
<a name="database_create" />
<h2>Creating a new password database</h2>
<p>
KeePassX stores your password entries into
a password database file when the it's not running.
To create a new password database, click the
<span class="gui">"New Database"</span>
icon on the program toolbar (it is the first icon from the
left on the toolbar).
</p>
<p>
Second, you need to set the <b>master key</b> for the
password database. This key is used to encrypt (ie. lock)
the password database so it cannot be read by anybody
else but you. The master key can be a password
or a key file or both.
If you check both, you must provide both the password
and the key file to every time you want to unlock the database.
</p>
<p>
If you decide to use a password,
<a href="http://www.us-cert.gov/cas/tips/ST04-002.html">
choose and protect it carefully</a> <img src="external.png" />.
The password should be strong, ie. long enough
(at least 8 characters) and preferably contain lower and
uppercase characters, numbers and special characters (e.g. !#?).
You should also memorize the password well, because
if you forget it, there is no way retrieving it later
from the locked database. You will be asked
to give the password twice to ensure that
there is no typing errors in the password.
</p>
<p>
The key file can be any file on your computer, e.g. a picture or
a text document.
You can also create a randomly-generated key file by first
selecting the key file check box and clicking
<span class="gui">"Generate Key File..."</span>.
You can store the key file for example on a USB memory stick,
to keep it with you everywhere.
</p>
<a name="password_add" />
<h2>Adding password entries</h2>
<p>
After you have created or opened a database, you
can add password entries to the database.
A password entry essentially consists of a title,
user name and password. It may have other entries
as well, such as URL (Internet link) and comments.
To add a new password entry, select a group from
the list on the left first, then
click the <span class="gui">
"Add New Entry"</span> icon on the program toolbar.
</p>
<p>
In the "New Entry" dialog you can enter
the information you want to into respective text boxes.
If you are creating a new account to e.g. a web forum,
you can use the password generator to generate strong
random passwords for you.
</p>
<a name="database_save" />
<h2>Saving the database</h2>
<p>
If you have added or edited entries in your database,
they are not automatically save to the database file by default.
You can save the database by clicking the <span class="gui">
"Save Database"</span> icon.
</p>
<p>
You may also want to
enable <span class="gui">"Automatically save database
after every change"</span> option from the
<span class="gui">"Extras"</span> >
<span class="gui">"Settings..."</span> >
<span class="gui">"General (2)"</span> page.
(On OS X, the page is found from
<span class="gui">"KeePassX"</span> (Application menu) >
<span class="gui">"Preferences"</span>.)
</p>
<a name="database_open" />
<h2>Opening a database</h2>
<p>
By default, on next startup, KeePassX opens a
<span class="gui">"Enter Master Key"</span>
dialog for the last used password database. If you wish
to open another password database, click
<span class="gui">"Cancel"</span>
and click <span class="gui">"Open Database"</span> icon
on the program toolbar and select the wanted password
database file from the file system. You can, of course,
do this at any point when the KeePassX main window is active.
</p>
<a name="password_edit" />
<h2>Editing and removing password entries</h2>
<p>
If you wish to edit a password entry, you can do
so by double-clicking on the entry title,
or by selecting the entry and then clicking the
<span class="gui">"View/Edit Entry"</span> icon
on the program toolbar.
</p>
<p>
To delete a password entry, first select the
entry and click <span class="gui">"Delete Entry"</span> icon
on the program toolbar or hit <tt>Ctrl-D</tt> (<tt>Cmd+D</tt> on OS X)
on the keyboard.
</p>
<a name="password_copy" />
<h2>Copying password (and user name) to the clipboard</h2>
<p>
You can copy the currently selected password by hitting <tt>Ctrl-C</tt>
(<tt>Cmd-C</tt> on OS X) and user name with <tt>Ctrl-B</tt> (<tt>Cmd-B</tt>
on OS X) on the keyboard. Then you can hit <tt>Ctrl-V</tt>
(<tt>Cmd-V</tt> on OS X) to paste the password or username
to any program that supports pasting from the clipboard.
</p>
<a name="autotype" />
<h2>Setup Auto-Type (currently Linux and OS X only)</h2>
<p>
<b>Auto-Type</b> is a feature that allows you to e.g. log in
to web page by hitting only one key combination.
KeePassX does the rest of the typing for you. Auto-Type reads
the title of currently active window on your screen
and matches it to the configured database entries.
If a matching window title is found from the password
database, it executes a predefined key sequence
(by default your username, <tt>TAB</tt>, password, <tt>ENTER</tt>) in
the active window. This feature is currently available
in the Linux and OS X versions only.
</p>
<p>
To enable Auto-Type, first go to
<span class="gui">"Extras"</span> >
<span class="gui">"Settings..."</span> >
<span class="gui">"Advanced"</span> page
and set the <span class="gui">"Global Auto-Type Shortcut"</span>
by clicking the text box and typing the desired
keyboard shortcut (e.g. <tt>Ctrl-Shift-N</tt>).
Click <span class="gui">"OK"</span> to exit the dialog.
</p>
<p>
Then, for example, open the web page where you
want to be able to log in with Auto-Type. Let's
for example open Google.com into Firefox and
try to do automated search with Auto-Type. Go
to Google.com in Firefox and you'll notice
that your window title is now "Google - Mozilla Firefox"
</p>
<p>
Now, create new password entry, that
contains user name "test".
Then, click the small <span class="gui">"Tools"</span>
button at the bottom of the <span class="gui">"New Entry"</span>
dialog, and select <span class="gui">"Auto-Type: Select target window"</span>
Select "Google - Mozilla Firefox" from the dropdown menu and
click <span class="gui">"OK"</span>. You should see now a new
line in the <span class="gui">"Comment:"</span> box, which reads:<br/><br/>
<tt>Auto-Type-Window: Google - Mozilla Firefox</tt><br/><br/>
Now you have associated that window title to this entry.
</p>
<p>
Finally, let's customize the Auto-Type key sequence
to just enter your username and hit <tt>ENTER</tt>.
Click again <span class="gui">"Tools"</span>
and select <span class="gui">"Auto-Type: Customize Sequence"</span>.
Now there's another new line in the <span class="gui">"Comment:"</span> box,
which reads:<br/><br/>
<tt>Auto-Type: {USERNAME}{TAB}{PASSWORD}{ENTER}</tt><br/><br/>
Change this line to:<br/><br/>
<tt>Auto-Type: {USERNAME}{ENTER}</tt><br/><br/>
So that it would just type in your username and hit <tt>ENTER</tt>.
Click <span class="gui">"OK"</span> to save the entry.
</p>
<p>
Now, you can test the Auto-Type by returning to the
Firefox window and hitting the global Auto-Type keyboard
shortcut (e.g. <tt>Ctrl-Shift-N</tt>) in it.
If everything went correctly, KeePassX should now enter
"test" in the search box and start the search query
by hitting <tt>ENTER</tt>.
</p>
<p>
By modifing the Auto-Type key sequence you can tailor
Auto-Type to suit almost every web login page you'll enter.
</p>
<p>
For OS X, there are two additional Auto-Type elements: <tt>{CLEARFIELD}</tt> and
<tt>{MACSENDKEYCODES}</tt>. <tt>{CLEARFIELD}</tt> clears the typing target to ensure
it is empty before typing into it. <tt>{MACSENDKEYCODES}</tt> should be put at the
beginning of an Auto-Type string to force the use of a more primitive typing
mechanism when the normal mechanism fails. A known case where this is required
is a web site where the login dialog is implemented in flash. The following
is an example:<br><br>
<tt>{MACSENDKEYCODES}{USERNAME}{TAB}{PASSWORD}{ENTER}</tt>
</p>
<p>
Also note that the use of <tt>{CLEARFIELD}</tt> may require the user to define
a somewhat larger Key Stroke Delay in Preferences when specified for a site
with flash-based login fields.

Minority Report computer interface designer demos the real thing (video)
At the big-think, big-demo TED conference in Long Beach last week, MIT Media Lab alumnus John Underkoffler demonstrated a real working version of the memorable grab-it-and-throw-it computer interface he designed for Tom Cruise in the hit science fiction movie Minority Report.
One reason Cruise’s gesture-based interface was so striking was that it was based on Underkoffler’s serious deep-end work in user interfaces. The g-speak Spatial Operating Environment requires gloves much like the ones Cruise wore as Precrime murder-prevention officer John Anderton.
g-speak’s website is hard to follow if you don’t already work in the field. Here’s my edit of their description of what the Spatial Operating Environment does, and why it’s useful:
Modern computers have high-definition, large-display graphical output. By contrast, the old mouse and keyboard are very narrow channels for input by humans.
Gestural input and output lets humans input data and commands to a computer system at a much higher rate than a keyboard and mouse ever could.
Where does gestural input win big over a mouse? Gestural input is measurably more efficient at performing complex navigation, sorting and selection tasks.
(Notice they didn’t say it’s faster at letting you compose a message than a QWERTY keyboard. Better speech recognition will probably be the solution for high-speed word input.)
Every graphical and input object in a g-speak environment has real-world spatial identity and position. Anything on-screen can be manipulated directly. For a g-speak user, “pointing” is literal. You reach out with the special gloves and point at, or touch, or grab, or manipulate objects visible in the display.
g-speak is designed to work on all kinds of displays. Wall-sized 3D screens can co-exist with desktop monitors, table-top screens and hand-held devices. Every display can be used simultaneously. g-speak moves data selectively to the displays that are most appropriate.
If you think gesture controls are hot, don’t miss Damian Rollison’s giant VentureBeat post on 16 companies building gesture-control tech.

Drone On
Well, I finally built me a drone so's I could fit in with all the cool kids. What follows is a short description of my experience with helpful links for someone else who would like to build a substantially similar quad. I built basically the cheapest quadcopter you could use for anything more than just crashing into stuff, a SK450 whose parts were primarily sourced from eBay — and usually with the very cheapest parts.
Keep that command running - keeprunning
I wanted to keep some programs running, which is to say restart them if they crashed, but I also wanted them to be able to exit normally. The platform is Linux, the problem is compiz, the solution is a very small shell script. Surely the internets will let me know if there is something grossly wrong with it. This script is not meant for long-running daemons, there are plenty of tools for that already.
Garbage Computers are Great!
For all my life, most of my computers have been hand-me-downs or upgrades. I've built a handful of PCs from scratch, but even most of the ones I built with new processors and motherboards had some hand-me-down parts. But it seems like recently a threshold was crossed where the computers available to just anyone (and not someone who knows "someone") for basically nothing began to be pretty good.
CarPC power: via relay
When you're putting together a so-called "Car PC", by which we usually mean a contemporary ATX-derivative computer installed into an automobile, you have a few hurdles to cross. The enclosure, interface, storage devices, and even the power management all become special problems. The power problems can largely be solved through the use of a Wide Input picoPSU, but what about systems outside of a 120W envelope, or systems where you need to switch more than the PC power? The answer is just one typical automotive relay.
CMS users don't care about Mobilegeddon
Right now, there is a massive flap occurring in the blogosphere which is known as "Mobilegeddon". Google is going to increase the relative ranking of pages which are available in both desktop and mobile themes, as opposed to only one or the other. This has got a lot of incompetent amateurs worried about whether their sites will vanish off the search landscape, but any Drupal (or other adequate CMS) user can solve this problem with a few clicks.
Windows XP: vmware to KVM migration
Like many others, I've become somewhat dependent on virtualization to reduce the number of computers and windows installs I have in my home. I recently took another stab at using open source virtualization, and I've had some success with WebVirtMgr, a libvirt-based VM management solution for Linux. This made me want to migrate some XP guests from vmware player to KVM, and I'm happy to say that this is relatively simple today once you figure out the precise sequence of events.
lspci for linux as a shell script
I needed a quick version of lspci for looking at some linux systems without pciutils, so I threw this one together in a couple of minutes.
It's very simple, it doesn't tell you what the devices are, but it does tell you what kind of devices they are and what their PCI ID is. Then you can go look that up online to figure out what they are. It wouldn't be a horrible stretch to add support for the pci.ids file, but it wasn't necessary for my purposes.
Wrong drive letter and can't boot Windows 7 after disk swap
I just got a nice Samsung EVO 850 SSD, and therefore got the chance to remove two spinning disks from my PC. But in order to make this happen, I had to move Windows to the SSD I had in my PC already. So I mounted the new SSD and formatted it ext4, and transferred Linux without a hitch. Then I booted up and used gparted to transfer Windows to the old SSD I'd just vacated, and it wouldn't boot. I thought these problems were over? I used my Linux install (with vmware player) to fix the problem just as I had used it (with gparted) to copy Windows from one volume to another.
Nexus 4 to Moto G: What's it like?
My LG E960, better known as the Google Nexus 4, decided to let me down. Around the same time, the radio stopped working properly and the digitizer stopped recognizing touches right in a fairly important spot — above the "e" key. Clearly it was time to take a right-hand turn and buy a new device from a different manufacturer. At just this moment, Amazon offered a discount on the second-generation (2014) Moto G, and the sale was made.

Stack Overflow is a question and answer site for professional and enthusiast programmers. It's 100% free, no registration required.
Say there is such table:
mysql> SELECT * FROM tags;
+---------+--------+
| post_id | tag_id |
+---------+--------+
| 1 | 2 |
| 1 | 3 |
| 1 | 1 |
| 2 | 1 |
| 2 | 2 |
+---------+--------+
5 rows in set (0.00 sec)
Field names are pretty self-explanatory. I want to select post_ids that have both 1 and 3 tag_ids, so in this example it's only 1. I thought of something like SELECT post_id FROM tags GROUP BY post_id HAVING ... After having I'd like to list tag_ids that are present in this group. How do I do that?

If post_id and tag_id both have an unique constraint, that should work too:
SELECT post_id
FROM tags
WHERE tag_id = 1 OR tag_id = 3
GROUP BY post_id
HAVING count(*) = 2;
If there aren't any unique constraints try:
SELECT DISTINCT post_id
FROM tags
WHERE tag_id = 1 OR tag_id = 3
GROUP BY post_id
HAVING count(DISTINCT tag_id) = 2;

Thanks, I decided to go with SELECT post_id FROM tags WHERE tag_id IN (1,3) GROUP BY post_id HAVING COUNT(1) = 2;, which scales well and is the closest to your solution – htf Jun 21 '10 at 10:09

You could try a self join (N tag_id -> N join) but probably it's not fast
SELECT t1.post_id
FROM tags t1 INNER JOIN tags t2 ON t1.post_id = t2.post_id
WHERE t1.tag_id = 1 AND t2.tag_id = 3

+1 but i'll add a select distinct to your request. – Fred Jun 21 '10 at 9:41

Doesn't really scale for an arbitrary amount of tags though. – Martin Smith Jun 21 '10 at 9:42

I've made some assumptions about your other tables. (i.e. that you have a table for posts that I have called posts and one with tag_id as the PK which I have called tag_table to avoid a nameclash with the posts/tags table that I can see you already call tags)
You want posts where there does not exist a tag in the list {1,3} for which there does not exist a matching record with the corresponding post_id/tag_id so you can use a double NOT EXISTS construct as below.
SELECT post_id
FROM posts p
WHERE NOT EXISTS
(SELECT * FROM tag_table tt
WHERE tag_id IN (1,3)
AND NOT EXISTS
(SELECT * FROM tags t
WHERE t.tag_id = tt.tag_id and
p.post_id = t.post_id)
)
Another alternative approach is to use Group By and Count. A review of approaches to this problem is here.

SELECT post_id
FROM ( SELECT post_id,
count(tag_id) AS counter
FROM tags
WHERE tag_id IN (1,3)
GROUP BY post_id
)
WHERE counter = 2
Use GROUP_CONCAT() for the second part of your question
SELECT post_id,
GROUP_CONCAT(tag_id ORDER BY tag_id ASC SEPARATOR ',')
FROM tags

How about
SELECT *
FROM tags
WHERE post_id in
(SELECT post_id AS pid
FROM tags
WHERE 1 IN (SELECT tag_id FROM tags WHERE post_id = pid)
AND 3 IN (SELECT tag_id FROM tags WHERE post_id = pid)
);

WHERE version of @Keeper's solution
SELECT DISTINCT t1.post_id
FROM tags t1, tags t2
WHERE
t1.post_id = t2.post_id AND
t1.tag_id = 1 AND t2.tag_id = 3
share|improve this answer
Don't think that the second clause of your OR is useful. – Fred Jun 21 '10 at 9:45
@Fred hmm.. yeah, you're right - will update – Amarghosh Jun 21 '10 at 9:49

ChrisL: free.fr still cutting at 15mn despite of reregister settings...
17:14:01 [fantasai]
also http://wiki.csswg.org/spec/css2.1#issue-211 is margin collapsing
17:15:46 [TabAtkins_]
dbaron: The issue with the root element is that we never say what precisely establishes the root BFC, whether it's the root element or osmething above it.
17:16:22 [TabAtkins_]
dbaron: The only place I've found that matters is if the root contains floats that extend below its normal content, or if the root has a background image vertically positioned anywhere other than "top".
17:16:33 [fantasai]
s/or/and/
17:16:45 [TabAtkins_]
dbaron: Gecko treats it as the root establishes a new BFC. Opera and Webkit don't.
17:17:02 [TabAtkins_]
fantasai: My inclination is to treat it as a BFC, since its margins don't collapse. It would make things more consistent.
17:17:32 [TabAtkins_]
alexmog: In IE we have a pagination problem, since if the root is a BFC then it won't break across pages.
17:18:04 [TabAtkins_]
fantasai: Why would the root take the size of the page?
17:18:49 [TabAtkins_]
alexmog: The root's layout box (whatever gets the scrollbar) gets set to the size of the first page.
17:19:02 [TabAtkins_]
alexmog: I may not be able to describe the problems properly, and they may be impl-specific.

17:20:07 [TabAtkins_]
dbaron: What matters in the test is the position of the orange stripe
17:20:14 [dbaron]
in first test, what matters is position of orange stripe
17:20:34 [TabAtkins_]
fantasai: In my test, if the blue box is large enough to hold the yellow, it's a BFC.
17:21:14 [TabAtkins_]
alexmog: It's not a BFC in IE9 or IE8. It was in IE7.
17:21:25 [TabAtkins_]
fantasai: I suspect this isn't a web compat issue, since we have differeing implementations.
17:21:47 [TabAtkins_]
fantasai: So I suggest to make it a BFC, because authors would get confused otherwise when root backgrounds don't contain their floats.
17:22:06 [TabAtkins_]
alexmog: Can I check with Paged Media issues and get back to you on that?
17:22:08 [TabAtkins_]
fantasai: Yup.
17:22:37 [TabAtkins_]
alexmog: Another issue. When pages change width, usually you take the width of the page where the BFC starts, and it stays that width. This is how we treat tables and such.
17:22:55 [TabAtkins_]
alexmog: But if the root is a BFC it has to act differently, so it can get larger if the page gets larger.
17:23:15 [TabAtkins_]
Bert: Related, we have 'overflow' which can't apply to <body>.
17:24:27 [TabAtkins_]
glazou: So do we need more time to decide on exactly how to handle this?
17:25:01 [TabAtkins_]
dbaron: I'm okay with changing Moz, though we do need to define where the root BFC comes from.
17:25:52 [shan]
shan has joined #css
17:26:05 [TabAtkins_]
glazou: Is that okay with everyone?
17:26:12 [dbaron]
I don't really understand alexmog's paged media issue, though.
17:26:42 [TabAtkins_]
alexmog: Is it okay to say that the root is not a BFC in paged media?
17:27:01 [dbaron]
I don't see any reference to block formatting contexts in the CSS 2.1 paged media chapter or in css3-page.
17:28:11 [TabAtkins_]
alexmog: It's not written anywhere, but it's something that people will have to solve as they implement Paged Media.
17:28:27 [TabAtkins_]
dbaron: is it related to BFCs specifically, or just to certian types of things that establish BFCs?
17:28:50 [TabAtkins_]
alexmog: It's certainly easier to say that everything that establishes a BFC has that behavior.
17:29:02 [Zakim]
-glazou
17:29:20 [TabAtkins_]
fantasai: You say IE has special behavior for tables and such across pages to make their widths stay the same across pages?
17:29:27 [TabAtkins_]
fantasai: You also do that for overflow:hidden?
17:29:29 [Zakim]
+??P0

17:30:03 [TabAtkins_]
alexmog: Yes, overflow:hidden elements also have this behavior.
17:30:28 [TabAtkins_]
fantasai: I'd prefer that overflow:hidden elements act like normal elements.
17:30:45 [TabAtkins_]
alexmog: So I don't strongly object to the root being a BFC, it would just make its pagination rules somewhat special.
17:31:14 [TabAtkins_]
fantasai: Yeah, the pagination rules aren't clear in the first place. We wrote something aobut chaning page widths into paged media, though it's not quite the same that you have.

17:31:27 [TabAtkins_]

17:33:28 [TabAtkins_]
TabAtkins_: It sounds like nobody has great disagreements, we just need to have some careful consideration of the issues and decide what to specify.
17:33:56 [TabAtkins_]
johnjan: Is this really something we want to change right now?
17:35:03 [TabAtkins_]
glazou: FF4 and IE9 are shipping with different behavior, so no matter what's decided there will be differeing impls.

Topic: Gamma section in CSS 2.1 spec
17:36:04 [TabAtkins_]
ChrisL: There was a discussion a few years ago from Chris Murphy, as a result of which we removed the section on gamma from CSS3 Color.
17:36:13 [TabAtkins_]
ChrisL: It was confusing and outdated.
17:36:29 [TabAtkins_]
ChrisL: It was recently pointed out to me that the same section is still there in CSS 2.1 as an informative note.
17:36:50 [TabAtkins_]
ChrisL: It has no conformance weight, but it's still confusing and outdated and has negative value. So we should delete it from CSS 2.1 as well.
17:37:21 [TabAtkins_]
RESOLVED: Remove the gamma note from 2.1.

arronei: There are two issues on the issues list that are super simple, 215 or 216. We discussed at the testing f2f, and I think we all agreed to kill them.
17:39:44 [TabAtkins_]
arronei: I'm not hearing any objections to leaving 215 undefined.
17:40:07 [TabAtkins_]
arronei: dbaron, you said FF is the only one that passes 216, and everyone else goes the other way. Do you object to dropping it?
17:40:24 [TabAtkins_]
dbaron: I'm fine with that. It can fall into a MAY.
17:40:44 [TabAtkins_]
RESOLVED: Resolve issue 215 as undefined, and drop issue 216.
17:40:49 [TabAtkins_]
Topic: Multicol algorithm.
17:40:51 [ChrisL]
the comment from Chris Murphy about being ignored at W3C
17:40:52 [ChrisL]
http://lists.freedesktop.org/archives/openicc/2011q1/002969.html
17:41:02 [TabAtkins_]
glazou: howcome's not on the call, but he quoted two of his messages.
17:41:25 [TabAtkins_]
alexmog: There are a few ways to treat a situation when there's no usable layout that satisfies the constraints.
17:41:41 [TabAtkins_]
alexmog: One way is to honor everything that is exactly defined, and just overflow if necessary.
17:41:42 [plinss]
s/drop issue 216/accept proposal for issue 216/
17:42:14 [TabAtkins_]
alexmog: Another is to keep content visible, so users on a phone dn't get a pretty layout, but it's usable.
17:42:32 [TabAtkins_]
alexmog: I think that nowhere in CSS do we alter the way we interpret properties based on whether an overflow is about to happen.
17:43:29 [TabAtkins_]
alexmog: If we really care about the end-user and want to show them content, when the design intent totally fails, the best thing for the user is to just drop to a single column as soon as possible when the multicol properties can't be satisfied.
17:43:44 [TabAtkins_]
alexmog: So once we shrink down to 0 col width, the next step should be to drop straight to 1 column.
17:44:39 [TabAtkins_]
alexmog: I think these are the only two situations (honor exactly, or drop to 1col quickly), and not to try and gradually relax properties, hovering around unusable states.
17:44:44 [Zakim]
-glazou
17:44:52 [TabAtkins_]
Bert: I like the principle, but what's the practical effect of 0-width columns?
17:44:59 [Zakim]
+??P0
17:45:05 [glazou]
Zakim, ??P0 is me
17:45:05 [Zakim]
+glazou; got it
17:45:09 [TabAtkins_]
alexmog: I think the page becomes unusable before 0px-wide columns.
17:46:01 [TabAtkins_]
alexmog: If the column is too small, the overflow just intrudes into the column-gap.
17:46:22 [Zakim]
-ChrisL
17:46:31 [TabAtkins_]
alexmog: If there's a single 0-width column, you'll see the overflow content. With multiple columns you won't.
17:46:47 [TabAtkins_]
szilles: I thought we discussed overflow columns just going to the right. Does that help in this case?
17:46:55 [Zakim]
+ChrisL
17:47:11 [TabAtkins_]
alexmog: Different situation - that's where column width is specified, but not count. This case is where column-count is specified, but not width.
17:48:14 [TabAtkins_]
szilles: So really, if you want to service multiple screens, setting a fixed number of columns is a bad idea.
17:48:26 [TabAtkins_]
alexmog: Without using media queries, yeah. Setting column-width is a better approach in general.
17:50:02 [TabAtkins_]
TabAtkins_: I think we should just honor things exactly. It can produce an unusable situation, but that's easy to fix right with media queries.
17:50:10 [TabAtkins_]
szilles: And what happens if I set both -width and -count?
17:50:15 [TabAtkins_]
alexmog: Current spec ignores -count in that case.
17:50:29 [TabAtkins_]
alexmog: I don't think that this extreme case is a good enough reason to add column-min-width.
17:50:35 [fantasai]
I thought the -count became the maximum column count?
17:50:51 [TabAtkins_]
alexmog: So we have two in favor of treating things exactly as specified.
17:50:54 [TabAtkins_]
bradk: Me to.
17:50:58 [TabAtkins_]
s/to/too/
17:51:01 [TabAtkins_]
szilles: i could live with it.
17:51:09 [TabAtkins_]
glazou: What's the option preferred by howcome?
17:51:24 [TabAtkins_]
alexmog: I'd prefer to ask him directly, but I think he was okay with either option, and just wanted consensus.
17:51:36 [TabAtkins_]
szilles: "Treating things exactly" is how the spec is now, right?
17:51:53 [TabAtkins_]
alexmog: No, the current spec somewhat relaxes count in some situations. It would remove 3 lines from the pseudo-algorithm.
17:52:24 [Zakim]
-cesar
17:53:04 [TabAtkins_]
fantasai: -count sets a minimum number of columns when used with -width, so if you set both values you effectively get a minimum width anyway.
17:53:19 [fantasai]
s/minimum number/maximum number/
17:53:30 [TabAtkins_]
alexmog: So I think we should ask howcome if he agrees with the consensus here.
17:53:35 [fantasai]
You get your column count combined with a minimum width for the columns
17:53:53 [TabAtkins_]
ACTION howcome to read the minutes from today and confirm if he agrees or not with the Multicol algo consensus.

17:54:25 [TabAtkins_]
Topic: :active disagreement between CSS and HTML
17:54:43 [fantasai]
Could even recommend that authors set -width when setting -count, so that the columns don't get too narrow.
17:54:52 [TabAtkins_]
Bert: I think the trouble is the definition of the word "activate".
17:55:04 [fantasai]
http://lists.w3.org/Archives/Public/www-style/2011Feb/0426.html
17:55:16 [TabAtkins_]
Bert: We thought we needed some indirection at the time of speccing, so we just used the word "activate" and let the source language define that.
17:55:25 [TabAtkins_]
Bert: But HTML already uses the word "activate" for something else.
17:55:50 [TabAtkins_]
Bert: So this is just a wording problem. They have to invent a new word for this or something, as the word "activate" is already taken in that spec.
17:55:54 [fantasai]
http://lists.w3.org/Archives/Member/w3c-css-wg/2011JanMar/0176.html
17:56:10 [TabAtkins_]
ChrisL: So it seems that HTML can just say "For CSS purpose, 'activate' means XXX"
17:56:36 [TabAtkins_]
Bert: Right. Another option is for HTML to use a different word for what they currently call "activate", and then use "activate" in the CSS sense.
17:57:26 [TabAtkins_]
TabAtkins_: I pinged Hixie this morning to ask him to change the wording.

Setting up a new server, and was just poking through the default my.cnf for centos7 beta2 and noticed there's no `innodb_buffer_pool_instances` variable: XtraDB/InnoDB Server System Variables - MariaDB Knowledge Base
Curious why you didn't include that?
Seems like a reasonable thing to include--it's the second thing I tweak in my.cnf normally after increasing the innodb_buffer_pool_size. You've got a number of other variables in there that are commented out for optional tweaking that I never touch.
FYI--the new default in MariaDB 10 is 8 instead of the old 1. It's a bit high for the VPSs that most folks on here run, but Maria seems smart enough that `SHOW ENGINE INNODB STATUS` on my 2GB VPS looks like there's only 1 instance. I don't know how it handles when it's a 4GB RAM (where I'd normally set instances at 2-3 depending on how much RAM I give MariaDB).

As per official doc MariaDB 10 already defaults innodb_buffer_pool_instances to 8 and that happens regardless of whether variable is set in /etc/my.cnf and has some smart auto detecting for >1GB buffer pools. Centmin Mod default innodb buffer pool = 48MB in size, so would hardly trigger innodb_buffer_pool_instances division automatically. So setting innodb_buffer_pool_instances would have no effect on default out of box Centmin Mod .08 beta install with MariaDB 10. Some settings are left to end users to tune for their specific needs. If are messing around with InnoDB specific /etc/my.cnf settings, then you should at least be this much clued into tuning for InnoDB performance in MySQL. Afterall, Centmin Mod is provided as is :)

Yeah, it's more I was hoping you could just add it as a commented out line.
I have an Ansible script that wraps Centminmod so I don't forget my various customizations that are scattered throughout various parts of centminmod (mysql character set utf8, turnoff ftp, increase memcache cache size, etc). And easy to wrap in ntpd, disabling passwords for sshd, etc. I basically just converted my "Notes_on_setting_up_a_server.txt" into code, so it's both faster and correctly documented.
For the my.cnf, I used a regex to find and replace a couple of lines. I considered using my own template, but you're always adding little tweaks here and there, and I don't want to miss anything. :D So I figured a regex using Ansible's lineinfile module was better than using my own template. But if innodb_buffer_pool_instances isn't in there, there's nothing for the regex to match against. :(
Definitely not worth worrying about if you don't want to, the two production VPSs that I run centminmod are both <8gb, so MariaDB defaults are fine. Mostly it just bothers my OCD that I can't parameterize the value. :whistle:

Zero worries mate. Get well and no rush on this. I'd be happy if it even got added in the next month. :)

I have this innodb_buffer_pool_instances on my my.cnf since switching to MariaDb 10, but only set to 4 as I only allow 4GB buffer poll.

Did some testing.
As long as innodb_buffer_pool_size is less than 1GB, there's only 1 buffer pool.
As soon as it increases beyond 1 GB, MariaDB immediately defaults to 8 buffer pools, which is too high for most VPS's.
For anyone in the 2gb-8gb RAM VPS range, since you'll likely be setting innodb_buffer_pool size > 1 GB, but less than 8gb, so be sure to also manually set innodb_buffer_pool_instances... ideally around 1GB each. Otherwise you'll think you're increasing performance, but you're probably actually decreasing it.
@eva2000 maybe make a note in the wiki page on mysql about this?

Yes, I have it like this:
innodb_buffer_pool_size = 4G
innodb_buffer_pool_instances = 4

yup my quoted info at MariaDB - Why does 123.08centos7beta02 my.cnf not include `innodb_buffer_pool_instances` variable? | Centmin Mod Community mentions this
it goes back to my initial assumption with regards to not enabling innodb by default, it is assumed that folks enabling innodb are versed and know innodb specific tuning requirements and that they would know or read innodb docs as such. It's why just blindly switching to innodb from myisam isn't a magic bullet that would give you the performance you may expect. You still need to know how to tune innodb parameters specifically. Centmin Mod only provides the tools, the rest such as software optimisation like nginx, php-fpm and mariadb mysql is up to end user :)

Seeing as Nexus phones have unlocked bootloaders, there is no need to wait for a rooted rom (if you are afraid it will never be rooted). Because you can just flash back to whatever rom/recovery you want. | {

💻 EAI-Taxonomy Code w/ DCLM
A 564 billion token dataset of high-quality code curated from web data using taxonomy-based filtering.
🎯 Dataset Overview
This dataset is part of the Essential-Web project, which introduces a new paradigm for dataset curation using expressive metadata and simple semantic filters. Unlike traditional code datasets that require complex domain-specific pipelines, our approach leverages a 12-category taxonomy to efficiently identify and extract high-quality code data.
💡 EAI-Taxonomy Code w/ DCLM (564B tokens): Documents targeting code that exhibit intermediate to advanced reasoning, combined with the DCLM classifier to filter for instruction-dense documents. Also includes mathematics content (51 - Mathematics) to match the scope of existing code datasets.
🏆 Performance
Our taxonomy-based approach achieves competitive results with significantly less curation effort:
| Dataset | HumanEval+ | MBPP+ | MMLU-CS | Curation Complexity |
|---|---|---|---|---|
| DCLM-baseline | 28.0% | 45.5% | 32.0% | General web filtering |
| OpenCoder FW | 26.2% | 45.8% | 27.7% | Complex domain pipeline |
| EAI-Taxonomy Code | 27.4% | 46.6% | 29.0% | Simple semantic filter |
| EAI-Taxonomy Code w/ DCLM | 28.7% | 45.0% | 47.0% | + DCLM classifier |
Results show competitive code generation performance with a +46.8% improvement in computer science knowledge (MMLU-CS) compared to baseline.
🔍 Key Findings
- Code Generation: All datasets perform within statistical error on single-function generation benchmarks (HumanEval+, MBPP+)
- Code Knowledge: Clear impact on general computer science knowledge when using taxonomy-curated data
- Efficiency: Achieves strong performance without complex domain-specific curation pipelines

EAI Taxonomy Classification
Comprehensive hierarchical classification system with primary and secondary labels - the most important feature of this dataset. The taxonomy is designed to provide detailed subject categorization, document type identification, content quality assessment, and extraction quality indicators.
Free Decimal Correspondence (FDC)
A Dewey Decimal-inspired classification system with 3-level hierarchical labels. The FDC provides nested categories where each successive level refines its parent category. It's designed to be compatible with the Dewey Decimal System for library cataloging.
Level Structure:
- Level 1: Top-level categories (0-9) covering broad subject areas like General works, Philosophy, Religion, Social Sciences, etc.
- Level 2: Sub-divisions (00-99) that refine Level 1 categories
- Level 3: Specific categories (000-999) that further refine Level 2 categories
| Component | Description | Path |
|---|---|---|
| Primary Code | Main classification code | eai_taxonomy.free_decimal_correspondence.primary.code |
| Primary Level 1 | Top-level category (0=General works, 1=Philosophy, 2=Religion, 3=Social Sciences, 4=Language, 5=Science, 6=Technology, 7=Arts, 8=Literature, 9=History/Geography) | eai_taxonomy.free_decimal_correspondence.primary.labels.level_1 |
| Primary Level 2 | Mid-level category | eai_taxonomy.free_decimal_correspondence.primary.labels.level_2 |
| Primary Level 3 | Specific category | eai_taxonomy.free_decimal_correspondence.primary.labels.level_3 |
| Secondary Code | Alternative classification code | eai_taxonomy.free_decimal_correspondence.secondary.code |
| Secondary Level 1 | Alternative top-level category | eai_taxonomy.free_decimal_correspondence.secondary.labels.level_1 |
| Secondary Level 2 | Alternative mid-level category | eai_taxonomy.free_decimal_correspondence.secondary.labels.level_2 |
| Secondary Level 3 | Alternative specific category | eai_taxonomy.free_decimal_correspondence.secondary.labels.level_3 |
We recommend this viewer for easily navigating the FDC categories when curating filters: https://www.librarything.com/mds

How to Load the Dataset
This section provides examples of how to load the EssentialAI/eai-taxonomy-code-w-dclm dataset using different Python libraries and frameworks.
Using Hugging Face Datasets (Standard Method)
The simplest way to load the dataset is using the Hugging Face datasets library:
from datasets import load_dataset
# Load the entire dataset
dataset = load_dataset("EssentialAI/eai-taxonomy-code-w-dclm")
# View dataset structure
print(dataset)
print(f"Number of examples: {len(dataset['train'])}")
You can also load the dataset in streaming mode to avoid downloading the entire dataset at once:
from datasets import load_dataset
# Load in streaming mode
dataset = load_dataset("EssentialAI/eai-taxonomy-code-w-dclm", streaming=True)
data_stream = dataset["train"]
# Iterate through examples
for example in data_stream.take(5):
print(example)
Using PySpark
For large-scale distributed processing, you can load the dataset using PySpark with the pyspark_huggingface library:
# First install the required library:
# pip install pyspark_huggingface
import pyspark_huggingface
from pyspark.sql import SparkSession
# Initialize Spark session
spark = SparkSession.builder.appName("EAI-Taxonomy-Code-w-DCLM").getOrCreate()
# Load the dataset using the "huggingface" data source
df = spark.read.format("huggingface").load("EssentialAI/eai-taxonomy-code-w-dclm")
# Basic dataset exploration
print(f"Dataset shape: {df.count()} rows, {len(df.columns)} columns")
df.show(10)
df.printSchema()
# Load only specific columns for efficiency
df_subset = (
spark.read.format("huggingface")
.option("columns", '["column1", "column2"]') # Replace with actual column names
.load("EssentialAI/eai-taxonomy-code-w-dclm")
)
# Run SQL queries on the dataset
df.createOrReplaceTempView("eai_taxonomy_code_w_dclm_dataset")
result = spark.sql("""
SELECT COUNT(*) as total_examples
FROM eai_taxonomy_code_w_dclm_dataset
""")
result.show()
Using Daft
Daft provides a modern DataFrame library optimized for machine learning workloads. You can load the dataset directly from Hugging Face:
import daft
# Load the entire dataset
df = daft.read_parquet("hf://datasets/EssentialAI/eai-taxonomy-code-w-dclm")
# Basic exploration
print("Dataset schema:")
df.schema()
print("First 5 rows:")
df.show(5)
If you need to access private datasets or use authentication:
import daft
from daft.io import IOConfig, HTTPConfig
io_config = IOConfig(http=HTTPConfig(bearer_token="your_token"))
df = daft.read_parquet("hf://datasets/EssentialAI/eai-taxonomy-code-w-dclm", io_config=io_config)
Installation Requirements
Make sure you have the required libraries installed:
# For Hugging Face datasets
pip install datasets
# For PySpark with Hugging Face integration
pip install pyspark_huggingface
# For Daft
pip install daft
