Java Classpath at Runtime
|
I am importing `import org.apache.commons.httpclient.*;` in a program, but whenever I go to run it, I have to include the JAR in the classpath. Why is this necessary? Are there any ways around this?

Is this a gcc optimization bug?
|
Here's my code:
bool func(const MY_STRUCT *const ptr, some_struct x, int y)
{
printf("IN: %p\n", ptr); // ok
// do something
printf("OUT: %p\n", ptr); // ok
return true;
}
void process(void)
{
... ...
for (i = 0; i < num; ++i) {
MY_STRUCT *ptr = obj->GetPtr(); // success
printf("BEFORE: %p\n", ptr); // ok
if (func(ptr, x, y)) {
continue;
}
printf("AFTER: %p\n", ptr); // <nil> when compile with -O2
printf("%s", ptr->data); // *** segment fault here ***
}
}
If I compile above code with -O0, everything works fine.
However, if I compile it with -O2, after the function `func` is called, the `ptr` become `NULL`!
Is this a gcc bug? Did anyone ever have encountered similar bug?
My gcc version is: `gcc version 3.4.5 20051201 (Red Hat 3.4.5-2)`
Thanks all in advance!

Is this a gcc optimization bug?
===
Here's my code:
bool func(const MY_STRUCT *const ptr, some_struct x, int y)
{
printf("IN: %p\n", ptr); // ok
// do something
printf("OUT: %p\n", ptr); // ok
return true;
}
void process(void)
{
... ...
for (i = 0; i < num; ++i) {
MY_STRUCT *ptr = obj->GetPtr(); // success
printf("BEFORE: %p\n", ptr); // ok
if (func(ptr, x, y)) {
continue;
}
printf("AFTER: %p\n", ptr); // <nil> when compile with -O2
printf("%s", ptr->data); // *** segment fault here ***
}
}
If I compile above code with -O0, everything works fine.
However, if I compile it with -O2, after the function `func` is called, the `ptr` become `NULL`!
Is this a gcc bug? Did anyone ever have encountered similar bug?

Orthographic Projection in Modern OpenGL
|
I'd like to set up an orthographic projection using only modern OpenGL techniques (i.e. no immediate-mode stuff). I'm seeing conflicting info on the web about how to approach this.
Some people are saying that it's still OK to call `glMatrixMode(GL_PROJECTION)` and then `glOrtho`. This has always worked for me in the past, but I'm wondering if this has been deprecated in modern OpenGL.
If so, are vertex shaders the standard way to do an orthographic projection nowadays? Does GLSL provide a handy built-in function to set up an orthographic projection, or do I need to write that math myself in the vertex shader?

Does video file gets downloaded in parts in video sites
|
I want to ask that suppose if i upload video files on youtube or any other video sharing site.
Then how does it streams the video.
I mean does it gets downloaded first on hard drive and then it plays.
I mean suppose i just dragged the video timline to half. Does that mean that only half video gets downloaded or full video gets downloaded.
because i have uploaded 2 hrs of video and if i want to see just 5 mins of video from half, i don't want that first my system downloads that 800MB file just to see 5 mins

Printing full backtrace in c++
|
I want to dump a backtrace from a C++ program in Linux in a similar format as it is done in gdb. I tried to use the backtrace() and backtrace_symbols() functions for this purpose. These returned function names and offsets. I can use the __cxa_demangle() function to get a readable function name.
Is there any way to get the file/line positions too, as it is done by gdb?

Possible to prevent search engine spiders from infinitely crawling paging links on search results?
|
Our SEO team would like to open up our main dynamic search results page to spiders and remove the 'nofollow' from the meta tags. It is currently accessible to spiders via allowing the path in robots.txt, but with a 'nofollow' clause in the meta tag which prevents spiders from going beyond the first page.
`<meta name="robots" content="index,nofollow">`
I am concerned that if we remove the 'nofollow', the impact to our search system will be catastrophic, as spiders will start crawling through all pages in the result set. I would appreciate advice as to:
1) Is there a way to remove the 'nofollow' from the meta tag, but prevent spiders from following only certain links on the page? I have read mixed opinions on rel="nofollow", is this a viable option?
`<a rel="nofollow" href="http://www.mysite.com/paginglink" >Next Page</a>`
2) Is there a way to control the 'depth' of how far spiders will go? It wouldn't be so bad if they hit a few pages, then stopped.
3) Our search results pages have the standard next/previous links, which would in theory cause spiders to hit pages recursively to infinity, what is the effect of this on SEO?
I understand that different spiders behave differently, but am mainly concerned with the big players, such as Google, Yahoo, MSN.

Hadoop On Demand
|
Is this Apache project (Hadoop On Demand) still actively being developed? I couldn't find any recent documentation but the concept (or motivation of the project) seems to be quite intriguing. My use case is to build relative large cluster (in-house) and allocate/deallocate portion of it to different users (I am not interested in using ElasticMapReduce or some other cloud service).
If there is any ppl who have used this or something similar, I would like to hear any comments on the experience of using it.

Creating a chat room layout in SWT
|
I want to build a chat room UI using eclipse rcp and wonder how to accomplish the heart of the UI, the message display:
Display a timestamp, followed by a right justified nick, followed by a message, e.g.
[01:00:20] <mike> sup
[01:00:25] <benjamin> hi
I currently use StyledText#setTabStops to get at least:
[01:00:20] <mike> sup
[01:00:25] <benjamin> hi
And wordwrap like this
[01:00:20] <mike> wordwrapping would really be
like icing on a cake
[01:00:25] <benjamin> hi
instead of this
[01:00:20] <mike> wordwrapping would really be
like icing on a cake
[01:00:25] <benjamin> hi
And if this isn't hard enough I'd like something like [XChat's selection behavior][1]
Some Ideas:
* Instead of one big StyledText I could divide it into three controls (one for each column) and sync the scrolling, but how to enable word wrap I don't know
* For each timestamp, nick and message a control is created and put in a gridlayout, but how to enable text selection across several messages I don't know

SSRS recursive count - how to get aggregates only for the children, not the parent?
|
**Disclaimer**: I'm an SSRS n00b, so not too many rotten tomatoes please :)
I have a hierarchy of employees and managers which I had Reporting Services build using the [Recursive Parent property](http://technet.microsoft.com/en-us/library/dd283103.aspx). Here's a crude representation:
-Jim Bob
Ray
-Steve
Ricky Bobby
Terry
For example, I need a count of the people under Steve, but when I call `Count(Fields!EmployeeID.Value, "Details", Recursive)` I get **3** instead of **2**. Of course, I can just subtract 1 in the case of a count, but this won't work when I need a sum. So the real question is **how do I get a recursive aggregate that excludes the parent?**
Additional info: I only have one group which is the default Details group. It's set up just like [this example](http://blog.infotoad.com/post/2009/08/10/Working-with-a-Recursive-Hierarchy-Group-in-SQL-Reporting-Services-2008.aspx), so I'm grouping by EmployeeID and I have the recursive parent set to ManagerID.

I then have a dictionary that looks like this:

Any books on the history of computer architecture?
|
I'm very interested in the history of computer architecture. Various elders that I've talked to have shared anecdotes and bits of wisdom that I've never seen in a computer science textbook.
I'm hoping for something on the order of Steven Levy's Hackers. Something that chronologically covers architecture of the earliest computers all the way through modern-day, and isn't afraid to go in-depth about the technical *and* human aspects.
Are there any recommendable books out there covering this topic?

is there any point in passing a pointer to a thread (java)?
|
assume we have 2 threads, thread A and thread B.
thread A is the main method and contain large data structures.
is it possible to create a second thread and pass the address(a pointer) of the data structure (local to thread A) to thread B so both thread can read from the data structure?
the point of this is to avoid the need to duplicate the entire data structure on thread B or spend a lot of time pulling relevant information from the data structure for thread B to use
keep in mind that neither thread is modifying the data

How do you document your methods?
|
As suggested, I have closed the question posed [here][1] and have broken it up into separate questions regarding code documentation to be posed throughout the day.
----------
The first question I have is, what are the guidelines you follow when you write documentation for a method/function/procedure? Do you always do doc-comments or do you try to let the method names speak for themselves?
What about within the code block? Do you find yourself writing a lot of line by line code? If you do, why do you feel the need for it?
What do you think should be the standard for documenting a small self-contained chunk of code (as opposed to the code as whole or tests)?
Do you find that your opinions differ depending on project size/type? On language you're using? On documentation tools available?

SharePoint/ASP.NET life cycle and databinding
|
I'm having a issue with databinding to a grid and what event to do it in. I'm using the DevExpress ASPxGridView, but it also happens with a few other grids I've tried.
We rely on a web part property to determine what data to retrieve, so we have to do the grid databinding in the OnPreRender event. If we do any grouping, then the expand/collapse of the grid doesn't work. If the databinding is moved to the OnLoad event then everything works fine. Is there a proper way to do this or is it just not supported?
Thanks

How to properly save a many-to-many relationship in Entity Framework.
|
I am currently working with the following EF code first model that has a many to many relationship between a Person and a Tag.
public class person
{
public Person()
{
this.Tags = new List<Tag>();
}
public int Id { get; set; }
public string Name { get; set; }
public virtual ICollection<Tag> Tags { get; set; }
}
public class Tag
{
public Tag()
{
this.People = new List<Person>();
}
public int Id { get; set; }
public string Name { get; set; }
public virtual ICollection<Person> People { get; set; }
}
public MyContext : DbContext
{
public DbSet<Person> People { get; set; }
public DbSet<Tag> Tags { get; set; }
}
I am then passing in a Json model to an MVC Controller that contains an existing person and is updating the person name along with also either adding or removing tags from the person's tag list.
I was having some issues getting the tags associated to the person properly. After a lot trial and error, I have come up with the following method that works.
[HttpPost]
public JsonResult Save(Person person)
{
//get ids of all tags that are associated with this person.
var tagIds = new List<int>();
foreach (var tag in person.Tags)
{
tagsIds.Add(tag.Id);
}
//clone the person minus the tags
var personToSave = person;
personToSave.Tags = new List<Tag>();
var context = new MyContext();
var existingTags = (from t in context.Tags
where t.People.Count > 0 && t.People.All(p => p.Id == person.Id)
select t).ToList();
//attach the person, so updates to the person object will save.
context.Entry(personToSave).State = EntityState.Modified;
if (tagIds.Count > 0)
{
//add new tags
var tags = context.Tags.Where(t => tagIds.Contains(t.Id));
foreach (var tag in tags)
{
//check if tags has no people and not already associated to this person.
if (tag.People.Count == 0 || tag.People.First(p => p.Id == person.Id) == null)
{
personToSave.Tags.Add(tag);
}
}
//remove tags that exist for this person, but were not specified in the list of
//tags on the person object that was passed into the method.
foreach(var existingTag in existingTags)
{
if (!tagIds.Contains(existingTag.Id)
{
context.Tags.Find(existingTag.Id).People.Remove(person);
}
}
}
//Finally if no tags were passed in the model and the person has tags, remove them.
if (tagsIds.Count == 0 && existingTags.Count > 0)
{
foreach (var oldTag in existingTags)
{
context.Tags.Find(oldTag.Id).People.Remove(person);
}
}
context.SaveChanges();
var message = string.Format("Saved {0} with {1} tags", person.Name, person.Tags.Count);
return Json(new {message});
}
All of this code just seems like a lot of work to add/remove tags from a person. I am still fairly new to Entity Framework, so I feel like I am probably missing something. I would like to know if I there is a better way to do this. Also, please note that this was the first thing that I was able to get working, so there are probably additional refactorings that could be applied.

Has anyone done any interesting development leveraging the Pega PRPC platform.
|
Most Pega implementations typically fall into say 1 of 5 non-interesting project kits. Think insurance policy underwriting, loan application underwriting, new account opening, case management workflows etc. Given the power of their BRMS I assuming there are folks that have done something besides one of these canned project kits. I'm curious to find implementations that have followed their own blueprint.

Only perform selector if target supports it?
|
How do call optional protocol methods?
@protocol Foo
@optional
- (void) doA;
- (void) doB;
@end
Now we have to check each time we want to call `doA` or `doB`:
if ([delegate respondsToSelector:@selector(doA)])
[delegate performSelector:@selector(doA)];
That’s just silly. I’ve come up with a category on `NSObject` that adds:
- (void) performSelectorIfSupported: (SEL) selector
{
if ([self respondsToSelector:selector])
[self performSelector:selector];
}
…which is not that much better. Do you have a smarter solution, or do you just put up with the conditionals before each call?

Ruby Deleting subdirectories that contain only a specific directory
|
I need to delete a bunch of subdirectories that only contain other directories, and ".svn" directories.
If you look at it like a tree, the "leaves" contain only ".svn" directories, so it should be possible to delete the leaves, then step back up a level, delete the new leaves, etc.
I think this code should do it, but I'm stuck on what to put in "something".
Find.find('./com/') do |path|
if File.basename(path) == 'something'
FileUtils.remove_dir(path, true)
Find.prune
end
end
Any suggestions?

MySQL stored procedure, handling multiple cursors and query results

How can I use two cursors in the same rutine? If I remove the second cursor declaration and fetch loop everthing works fine. The rutine is used for adding a friend in my webapp. It takes the id of the current user and the email of the friend we want to add as a friend, then it checks if the email has a corresponding user id and if no friend relation exists it will create one. Any other rutine solution than this one would be great as well.

Webdrive errors from Firefox
|
A client ran a small test for me, her Firefox fails with errors...and yet it runs on mine.
> First is "Your Firefox profile cannot be loaded. It may be missing or
inaccessible.", which is then followed by "The update could not be
installed. Please make sure there are no other copies of Firefox
running on your computer, and then restart Firefox to try again." Then
a new Firefox window is opened with an empty tab in it (and no

Webdrive errors from Firefox
===
A client ran a small test for me, her Firefox fails with errors...and yet it runs on mine.
> First is "Your Firefox profile cannot be loaded. It may be missing or
inaccessible.", which is then followed by "The update could not be
installed. Please make sure there are no other copies of Firefox
running on your computer, and then restart Firefox to try again." Then
a new Firefox window is opened with an empty tab in it (and no
navigation bar, unlike all the other Firefox windows I have opened
right now).
Is she going to have to add some addons to her browser?

Help with C printf function
|
I am trying to duplicate NSLog but without all of the unnecessary dates at the beginning. I have tried the following c function (I made myself), but it wont log any other values that are not NSStrings. Please could you tell me how I could do it so that it would log any value?
static void echo(NSString *fmt, ...) {
printf("<<<<<<<%s>>>>>>>", [fmt UTF8String]);
}
Thanks in advanced.

What is the necessary Math skills needed for a particular field?

Do you have an overview of what kind of Math is most useful for which field? For example, if a linux kernel developer, what type of math knowledge does one programmer need? For a driver developer, what type of Math is needed? It seems to me that except for computer science related fields and game programming, do other IT fields need hardcore Math?

How to convert data downloaded from a web site into the correct encoding?
|
I've been having issues with data downloaded using a .net WebClient control, in that I seem to have little control over the encoding of the data that I get back from a web server.
The specifics of the question are in the post linked below, but I want to ask the question in a more general sense as the answer is not really helping (not the answerer's fault!).
http://stackoverflow.com/questions/4716470/asp-net-c-webclient-downloadstring-returns-string-with-perculiar-characters
**The real problem is that supposedly there is no way to detect the encoding of a response from a web server, and the webserver may not respond using the encoding specified in the headers.**
*If* this is true, how do web browsers such as IE, Firefox and Chrome work out how to decode the stream when you use the view source functionality?
It must be possible, this seems like a really fundamental requirement!

What is the best way to render LESS.js stylesheets in node.js using express?
|
I have a small node.js app (my first) that I want to have compile it's less.js stylesheets when the server loads. The point I'm starting at is the express example app for jade where it appears it compiles it's SASS templates when the server is created:
var pub = __dirname + '/public';
var app = express.createServer(
express.compiler({ src: pub, enable: ['sass'] }),
express.staticProvider(pub)
);
I saw this and hoped it would be as simple as changing sass to less but that doesn't appear to work.
Is there a different approach I should take? Is there something I'm missing? I can't find the documentation on the .compile method anywhere.
Thanks!

Anagrams finder in javascript

I am supposed to write a program in JavaScript to find all the anagrams within a series of words provided. e.g.: "monk, konm, bbc, cbb, dell, ledl"
The output should be categorised into rows:
1. monk konm;
2. bbc cbb;
3. dell ledl;
I already sorted them into alphabetical order i.e.:
"kmno kmno bbc bbc dell dell"
and put them into an array.
However I am stuck in comparing and finding the matching anagram within the array.
Any help will be greatly appreciated.

I am going to be implementing a network protocol (specifically, SFTP) and I wondered if there are any general rules-of-thumb to follow?
At the moment it seems like a mammoth task and I'm at a loss as where to start.
I'm looking for:
- Tips
- Best practices
- Possible design patterns
- Experiences
Try to keep it applicable to network protocols in general.
Thanks!

How to setup a multi-server network for a web application
|
I am experienced with development, but not with servers and networking. I am developing an application and stability is critical. What I am wondering is how my network should be structured and how it will all work?
To create a stable, fast and expandable network, I think I will need 2 web servers, 2 database servers and a load balancer. The reason I believe I need 2 web servers and 2 database servers is not for performance, but for failover.
Is this the best solution? Where would my application files & databases reside? Could there be a "central stand alone" storage point that is RAID10 and all servers read from it? I think this because it doesn't sound logical to duplicate the files across the servers.
The most amount of money I want to spend on getting the network setup would be about $10k. Will this be enough? The servers don't have to be huge at the beginning as there will not be enough transactions to overload even a small server. It is the critical stability that I am after.
If anyone can explain in laymen terms how my network should be setup it would be appreciated. If it is needed, this is a web based .net 4.0 application with sql server 2008 running multiple databases.

Algorithm analysis: Am I analyzing these algorithms correctly? How to approach problems like these
|
1)
x = 25;
for (int i = 0; i < myArray.length; i++)
{
if (myArray[i] == x)
System.out.println("found!");
}
I think this one is O(n).
2)
for (int r = 0; r < 10000; r++)
for (int c = 0; c < 10000; c++)
if (c % r == 0)
System.out.println("blah!");
I think this one is O(1), because for any input n, it will run 10000 * 10000 times. Not sure if this is right.
3)
a = 0
for (int i = 0; i < k; i++)
{
for (int j = 0; j < i; j++)
a++;
}
I think this one is O(i * k). I don't really know how to approach problems like this where the inner loop is affected by variables being incremented in the outer loop. Some key insights here would be much appreciated. The outer loop runs k times, and the inner loop runs 1 + 2 + 3 + ... + k times. So that sum should be (k/2) * (k+1), which would be order of k^2. So would it actually be O(n * k^2)? That seems too large. Again, don't know how to approach this.
4)
int key = 0; //key may be any value
int first = 0;
int last = intArray.length-1;;
int mid = 0;
boolean found = false;
while( (!found) && (first <= last) )
{
mid = (first + last) / 2;
if(key == intArray[mid])
found = true;
if(key < intArray[mid])
last = mid - 1;
if(key > intArray[mid])
first = mid + 1;
}
This one, I think is O(log n). But, I came to this conclusion because I believe it is a binary search and I know from reading that the runtime is O(log n). I think it's because you divide the input size by 2 for each iteration of the loop. But, I don't know if this is the correct reasoning or how to approach similar algorithms that I haven't seen and be able to deduce that they run in logarithmic time in a more verifiable or formal way.
5)
int currentMinIndex = 0;
for (int front = 0; front < intArray.length; front++)
{
currentMinIndex = front;
for (int i = front; i < intArray.length; i++)
{
if (intArray[i] < intArray[currentMinIndex])
{
currentMinIndex = i;
}
}
int tmp = intArray[front];
intArray[front] = intArray[currentMinIndex];
intArray[currentMinIndex] = tmp;
}
I am confused about this one. The outer loop runs n times. And the inner for loop runs
n + (n-1) + (n-2) + ... (n - k) + 1 times? So is that O(n^3) ?? I don't know how to approach this one. Any

So would it actually be O(n * k^2)? That seems too large. Again, don't know how to approach this.
4)
int key = 0; //key may be any value
int first = 0;
int last = intArray.length-1;;
int mid = 0;
boolean found = false;
while( (!found) && (first <= last) )
{
mid = (first + last) / 2;
if(key == intArray[mid])
found = true;
if(key < intArray[mid])
last = mid - 1;
if(key > intArray[mid])
first = mid + 1;
}
This one, I think is O(log n). But, I came to this conclusion because I believe it is a binary search and I know from reading that the runtime is O(log n). I think it's because you divide the input size by 2 for each iteration of the loop. But, I don't know if this is the correct reasoning or how to approach similar algorithms that I haven't seen and be able to deduce that they run in logarithmic time in a more verifiable or formal way.
5)
int currentMinIndex = 0;
for (int front = 0; front < intArray.length; front++)
{
currentMinIndex = front;
for (int i = front; i < intArray.length; i++)
{
if (intArray[i] < intArray[currentMinIndex])
{
currentMinIndex = i;
}
}
int tmp = intArray[front];
intArray[front] = intArray[currentMinIndex];
intArray[currentMinIndex] = tmp;
}
I am confused about this one. The outer loop runs n times. And the inner for loop runs
n + (n-1) + (n-2) + ... (n - k) + 1 times? So is that O(n^3) ?? I don't know how to approach this one. Any

Which recommended Perl modules can serialize coderefs?
|
As far as I can tell `Storable` can't. I only found `YAML` (and `YAML::XS` which [I can't really get to work][1]).
Are there other alternatives?
What would you recommend?

How to limit the list of ciphers available to openssl
|
Is there a way to force openssl to use a particular cipher by default (or to some how set a preference list). If I run openssl from the command line connecting to a particular server as follows:
openssl s_client -connect host:port -cert cert.pem
It fails with error message `tlsv1 alert internal error`. However if I force the cipher as in the following command line example then it works:
openssl s_client -cipher DHE-RSA-AES256-SHA -connect host:port -cert cert.pem
I am experiencing this problem with OpenSSL 1.0.1. The problem does not exist if I use openssl 0.98 (but this causes other issues). I read some where about a similiar problem which was solved by limiting the ciphers available to OpenSSL (version 1). Can any one shed some light on how to do this?
I am ultimately using php but would prefer to solve this problem at an openssl level if possible.

Add "Select top 1000" command to toolbar in SSMS

I am using SQL server management studio (2008) quite a lot these days. If it had a "Select top 1000" command in the toolbar,(or a shortcut key) it would make my life a lot easier. Is there any way i can do it. I tried looking in the customize dialog, but cant find that command there.

cakephp: How can i add dropdownlist in default.ctp ?
|
In default.ctp I want to add two dropdownlists.
One is list of year from 2010 to 2020 and the another one is a list of month from January to December.
How can i do this ?
Do i have to create form for this ? like
echo $this->Form->create...
echo $this->Form->end..
Or can i just add two dropdownlists and a search button ?
The if i click the "Search" button it will go for posts/archive action and display those posts with that "year-month"
Can anyone post sample code for this?
Thanks in advance.

Interspire Email Marketer Configuration
|
Im trying to setup Interspire email marketer for a client. I have a working configuration of it on the VPS but this one is having issues! I have transferred it from their old server and setup the new database...
Im thinking it could be to do with the PHP settings / MY SQL memory or buffer.
when I send to a small list, it works fine, but when its faced with a larger list it wont do the business... it wont even start sending.
Ive been comparing the two configurations:
http://oldhabs.com/emailmarketer/check_iem.php (This one works)
http://servedby.intelligentmedia.co.uk/check_iem.php (This is the one that wont send to a large list)
Ive been getting these errors from Interspire itself:

I know the top error is to do with the wrong bounced address... I think. Would this stop the send to that list?
Ive checked the server logs, and Im not getting any errors.
Any help you can give is greatly appreciated.

"Like" timestamp
|
I'm creating an app that tracks activity on a user's wall: posts made on the wall, and likes and comments in those posts.
I would like to save that activity into a database, and for the script to look for new activity based on the most recent timestamp saved to the database.
This is fairly easy to accomplish for posts and comments which have their creation time returned, but I haven't been able to find anything similar for post likes. The closest I've come is returning a user's likes, but that only for pages.
Are post likes even timestamped, and if they are, is there any way to retrieve that information?
The only alternative is running through the user's posts every time we need to check activity in his wall, but it's kind of an intense process...

Accessing a logger in a Java application
|
I have a question regarding logging in a Java application. I want to log the main user actions and possible errors with user friendly messages. Therefore, I have two appenders for the logger: one shows errors (level = error) in dialogs and the other writes the logs of the current user session into an html-file so that the user could send this file back if something goes wrong.
To avoid having the logger creation in every class (private Logger logger = …) I have a static reference of the configured logger in a class App which has also the methods for accessing the logger:
public class App {
private static Logger logger = Logger.getLogger("logger name");
…
public static void logError(String message, Throwable cause) {
…
}
public static void logInfo(String message) {
…
}
}
The logging is mainly done in the UI classes:
class UIWidget extends UIFrameworkWidget {
void aMethod() {
try {
someBusinessLogic();
} catch (Exception e) {
App.logError(“log message”, e);
}
}
}
Is this a good practice? (Note that the widgets are created by the framework.)
Thanks in advance for answers, comments, or hints on this

Therefore, I have two appenders for the logger: one shows errors (level = error) in dialogs and the other writes the logs of the current user session into an html-file so that the user could send this file back if something goes wrong.
To avoid having the logger creation in every class (private Logger logger = …) I have a static reference of the configured logger in a class App which has also the methods for accessing the logger:
public class App {
private static Logger logger = Logger.getLogger("logger name");
…
public static void logError(String message, Throwable cause) {
…
}
public static void logInfo(String message) {
…
}
}
The logging is mainly done in the UI classes:
class UIWidget extends UIFrameworkWidget {
void aMethod() {
try {
someBusinessLogic();
} catch (Exception e) {
App.logError(“log message”, e);
}
}
}
Is this a good practice? (Note that the widgets are created by the framework.)
Thanks in advance for answers, comments, or hints on this

Java - app works in Windows but not on Linux
|
I'm a beginner in Java and made my first project Quadratic Equations solver. It works fine on Windows (the platform I developed it on), but it is supposed to work on other platform too, (isn't it?). Well, this one doesn't work on Linux(BackBox, PuppyLinux), i tried but it shows up that its not an executable. What could be the possible causes of this failure?
P.S I'm REALLY a beginner in "cross-platform", especially Java.

Facebook canvas app authorization
|
My app which is built-in to FB canvas needs to authorize users before processing any action. I see two options for doing it:
1. To authorize the user on FB upon every his action (redirecting to https://www.facebook.com/dialog/oauth?blahblah)
2. To create a persistent cookie so the app won't need to FB authorize for every action.
My questions are:
For the 1st case: is it OK for FB to be asked for user authorization so often?
For the 2nd case: how can i catch the FB user has changed at the same PC? My app's cookie will remain old.
Thank you!

Best way to do PHP hooks
|
I'm wondering what the best way is of handling hooks in a PHP application - so I can insert custom or 'plug in' functionality without modifying the main body of code. I know Wordpress features something like this.
Is it really alright to do something as follows:
if (file_exists('file_before'){ include('file_before'); }
print 'hello';
if (file_exists('file_after'){ include('file_after'); }

Asynchronous sockets vs synchronous
|
I have a question about asynchronous sockets. It's been bothering me for the last few months and thought I should wise up and get the facts from the pros here.
I have an incoming stream from a client which I want to take in the data. This incoming stream requires initial setup via strings before it will commence sending the data.
I have heard about the powerful scalability of asynchronous tcp servers like node.js. My question is whether can I use node.js or any other asynchronous tcp server to handshake with this client and receive the incoming stream.
You can think of the incoming data as an stream of stock data or electricity usage at a given point in time. In essence the data will be streaming in continuously.
Pls let me know what other information I need to share to help me understand asynchronous sockets and how to use it.

Random deleting of text file on java learner training
|
So I'm working on a project where we created a supervised learner in Java. It uses a weight .txt file with about 15 lines (one number per line) that gets opened and closed twice per run. Opening and closing happens directly before and directly after reading/writing.
Because of the way the code is structured (not our decision), I cannot run our training code in a loop. So I setup a batch script that simply iterates over a loop, during each iteration running our code (and thus updating our file), waiting for a few seconds, and then repeating.
The problem is that every few hundred runs or so randomly, all the contents of our file gets deleted. The file still exists, but all the content is clear. Sometimes it'll happen on the 100th run, sometimes it'll happen on the 200th, sometimes on the 3rd.
Assuming it's not our code that is the problem, what could possibly cause this? Or possible fix?
Specs:
Windows 7
Making 'java' calls to execute the .class file
modifies a .txt file in the same directory
Any help is greatly appreciated.

jQuery Autocomplete with multiple inputs
|
I have an autocomplete field which I would like to augment by providing a drop down for categories as well, in the hopes that this makes it even easier to search on. This would take the category id from the drop down and then pass this in along with the search text to my server side Autocomplete Function.
I am using the jQuery autocomplete plugin found here:
http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/
The demo page is here:
http://jquery.bassistance.de/autocomplete/demo/
Perhaps this is already explained in the demo somehow, but I'm just not seeing it. I am able to get the data out from JSON and split it into multiple fields.
It doesn't matter much, but I am using ASP.NET MVC as well.

How to fuzzy match a short bit pattern in a long one?
|
I encounter a problem when try to match a short bit pattern in a long one: I have one long bit pattern, e.g. 6k bits, stored in a char array, also a short one, say 150 bits, stored in a char array, too. Now I want to check whether the short bit pattern is in the long bit pattern. While there is no need for short bit pattern to match some part of long bit pattern exactly, I will define a threshold, if the bit-error-rate under it, I will take the two pattern match.
Given the misalignment problem, I can't come up with an elegant solution. One way I can find out is convert the bit pattern into char pattern, i.e. convert bit 1 to '1', 0 to '0' and apply some string matching algorithm. But I'm afraid it may cost memory 7-8 times more burden my system. Someone around me recommend the [Rabin Fingerprint][1], however it seems not designed for this kind of problem.
Hope you can give me a hand.
Thanks and best Regards.

jQuery Selector Question

The same as just looping through each element using jQuery's .each function?

Scalabilty of Java middleware between Core banking and ATM Server
|
I have a requirement to build a Java module which will act as a router between ATM Server or any other Point of Sale which accept cards, and a core banking system.
This module should interpret requests from the end points and do some processing before it communicate with the core baking system. The communication will be through the java implementation of TCP IP Sockets. The end points like ATM will be the server & this middle ware will be the client. This application will keep on listening for the server messages & should be capable of interpreting simultaneous requests in range of 1k to 2k.
The idea is to have one client socket thread listening for server messages and handle each of the received messages in different threads. Is there any issue in my basic idea?
Is there is any open source application available to cater my requirements?
Thanks in advance for your advice.

what determines the memory model?
|
Specifically this question is about flat and segmented model in real mode. I am reading a book on assembly which mentions that on DOS the COM files use flat memory model and EXE files use segmented memory model. However I am not understanding what tells DOS which memory model to use. I am asking this question because I am reading about bootloaders.

MSSQL - How many users do I *really* need?
|
I'm setting up an application, and I'm looking into purchasing a license for MSSQL. My question is pretty simple (though may have a complicated answer...)
How many users accounts do I *really* need, for SQL Server?
The way I see it, I'd give one master administration account, maybe 2 or 3 user accounts, and then one application-based account.
My application will likely have about 30-40 users, with the rare possibility of having 4-5 people being simultaneous users. But as I see it, I'd set up a BLL with the 30-40 accounts - and the BLL would have the SQL account, that all 30 accounts would use to query the DB through...
I'm just wondering what people's take on this is. Is that the way to go, or do I have the wrong idea of architecture here?
Thanks in advance!

changing text colour using system colours from a combo box
|
I am in the process of making a text editor, I am trying to set up some functionality so that the user can select a colour from a combo box and that will change the colour of the text. Right now my combo box is being loaded with the system colours in xml using a resource like so
<ToolBarTray.Resources>
<ObjectDataProvider MethodName="GetType" ObjectType="{x:Type sys:Type}" x:Key="colorsTypeOdp">
<ObjectDataProvider.MethodParameters>
<sys:String>System.Windows.Media.Colors, PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35</sys:String>
</ObjectDataProvider.MethodParameters>
</ObjectDataProvider>
<ObjectDataProvider ObjectInstance="{StaticResource colorsTypeOdp}" MethodName="GetProperties" x:Key="colorPropertiesOdp">
</ObjectDataProvider>
</ToolBarTray.Resources>
<ComboBox Name="colors" ItemsSource="{Binding Source={StaticResource colorPropertiesOdp}}" DisplayMemberPath="Name" SelectedValuePath="Name" MinWidth="100" ToolTip="Color" />
I am trying to make a selectionChanged event code that will change the text to the system colour selected by the user, if you need to see more code or need more info let me know.
Thanks, Beef

Are language specific tests good for interview?
|
I wonder whether are language specific tests good for selecting potential candidates? Questions such as
1. Javascript's Syntax
2. .Net API( What class to use if you want to send email via Microsoft Outlook)
3. Specific SQL queries ( What's the difference between **inner join** and **join**?)
4. ASP.NET ( What event/ method is executed before/after Page_Load?)
and so on. The candidates have to answer them in a given time frame.

Many applications have associated help that you invoke by pressing F1.
What PowerShell command would launch the application AND open the help?
Applications I have in mind are Powershell ISE, Visual Studio, Microsoft Office, etc.
Is there a standard mechanism for this?

Using $_POST information only once
|
I have some information which gets passed from a form and needs to be used once and only once. I can collect it nicely from $_POST but I'm not sure which is the "best" way to ensure that I can only use it once, i.e. I want to avoid the user pressing F5 repeatedly and accessing the function more than once.
My initial thought was to set a session variable and time the function out for a set period of time. The problem with that is thay could have access to the function again after the set period has elapsed.
Better ideas welcomed!

Should Threads be avoided if at all possible inside software components?
|
I have recently been looking at code, specifically component oriented code that uses threads internally. Is this a bad practise. The code I looked at was from an F# example that showed the use of event based programming techniques. I can not post the code in case of copyright infringements, but it does spin up a thread of its own. Is this regarded as bad practise or is it feasible that code not written by yourself has full control of thread creation. I do point out that this code is not a visual component and is very much "built from scratch".
What are the best practises of component creation where threading would be helpful?
I am completely language agnostic on this, the f# example could have been in c# or python.
I am concerned about the lack of control over the components run time and hogging of resources, the example just implemented another thread, but as far as I can see there is nothing stopping this type of design from spawning as many threads as it wishes, well to the limit of what your program allows.
I did think of methods such as object injecting and so fourth, but threads are weird as they are from a component perspective pure "action" as opposed to "model, state, declarations"
any help would be great.

Programmatically creating new user on MAC OS using objective-c or any Cocoa API?

I'm trying to create new user within my Application. I know that is possible using dscl and NSTask.But does anyone know how it is possbile to do with any Cocoa API , or programmaticaly using objective-c? within code , not using bash commands , like here
sudo niutil -create / /users/newuser
sudo niutil -createprop / /users/newuser uid 502
sudo niutil -createprop / /users/newuser gid 502
sudo niutil -createprop / /users/newuser realname "Longer Name"
sudo niutil -createprop / /users/newuser home "/Users/newuser "
sudo niutil -createprop / /users/newuser shell "/bin/tcsh"
sudo niutil -createprop / /users/sharedDir shell "Public"
sudo niutil -createprop / /users/newuser passwd "*"
sudo passwd newuser
sudo ditto /System/Library/User\ Template/English.lproj /Users/newuser
sudo chown -R newuser :group /Users/newuser
I was told that is possible to do using **Open Directory Framework**, but couldn't find usefull documentation. Thanks.

Get changes in content provider
|
I'm developing an application that syncs a remote calendar with an Android device.
Everything works fine, but now I want to make it a bit faster by letting the Android device only sync events that got edited by the user (with Android Calendar). So I need to know which events got edited.
I've been looking into `ContentObserver` but that doesn't seem like a good solution since I would have to register an observer for each event in the calendar. And I don't even know if the observer would still be there if I restarted the device.
Another solution I came up with is to store a copy of all events in a local database. That database would get updated on each sync. And before each sync we could compare that database with the Android Calendar provider...
Is there an easier way to do this?
Thanks,
Gillis

If condition in a webgrid
|
I am using this webgrid in my view.
<div class="grid">
@{
var grid = new WebGrid(Model.SearchResults, canPage: true, rowsPerPage: 15);
grid.Pager(WebGridPagerModes.NextPrevious);
@grid.GetHtml(
htmlAttributes: new { @style = "width:100%", cellspacing = "0" },
columns: grid.Columns(
grid.Column(header: "Customer Name", format: (item) => Html.ActionLink((string)item.FullName, "ShowContracts", new { id = item.UserId }, new { @style = "color: 'black'", @onmouseover = "this.style.color='green'", @onmouseout = "this.style.color='black'" })),
grid.Column(header: "SSN", format: item => item.SSN)
))
}
</div>
I search with SSN and display the results in a webgrid. The displayed data is dummy data.
I have a bool AccountVerified in my viewmodel, now I should not give action link to the accounts which are not verified and display text next to them saying account verification pending. Can someone help me on this?

How to change background color of DateTimePicker control under Windows Vista / 7
|
My question is the same as the one at http://stackoverflow.com/questions/198532/changing-the-background-color-of-a-datetimepicker-in-net. Unfortunately, the solution there doesn't work in Windows Vista/7 when visual styles are enabled. It does work fine if I disable visual styles, but that isn't an acceptable solution for my application.
How do I change the background color of a .NET WinForms DateTimePicker under Windows Vista / 7 when visual styles are enabled?
Any answers written from a C++ / Windows API perspective are welcome as well; I am experienced enough to translate a solution from one platform to another. I just ask it from a C# / WinForms perspective as there are a lot of developers who use it.
**Edit:** Also I should add that suggestions to owner-draw the entire control are at the very bottom of my possible list of solutions as it sounds like a ton of work. Existing efforts I've seen seem very incomplete.

Faux Columns - IE vs Chrome - Different opacity?
|
I don't know how to explain to you the trouble by using faux columns. So I'll [show][1] it to us.
IN the first image you can see the faux columns rendered by Chrome. In the second by IE8. How you can see, on IE there is a different opacity, and i don't know why.
This is the HTML code :
<div class="commentsWide">
<div class="commentContent">
<div class="commentsWide1">
<a class="lblackbbu" href="index.php?explore=userview&userv=chevr">chevr</a>
</div>
<div class="commentsWide2">
side A sorry i forgot to mention :P
</div>
<div class="commentsWide3">
<div class="commentsWide3A"> </div>
<div class="commentsWide3B">11:06:20</div>
<div class="commentsWide3C">30-06-2010</div>
</div>
</div>
</div>
And this the CSS :
.commentsWide{width:690px; float:left; background-color:#999999; color:#000000; border-bottom:1px #000000 solid; padding-top:5px; padding-bottom:5px; padding-left:10px; padding-right:10px;}
.commentContent{width:690px; float:left; background-image:url(../img/comments_background.png);}
.commentsWide1{width:120px; float:left;}
.commentsWide2{width:450px; float:left; padding-left:10px; padding-right:10px;}
.commentsWide3{width:100px; float:left; text-align:right; font-weight:bold;}
.commentsWide3A{width:20px; height:35px; float:left; padding-left:10px; padding-top:5px;}
.commentsWide3B{width:70px; float:left; text-align:right; font-size:14px;}
.commentsWide3C{width:70px; float:left; text-align:right; font-size:12px;}
Why this happens? And how can I fix this trouble?

Is it bad to have 3 levels of divs on the z-axis
|
As a general rule of design is it looked down upon to have more than one div ontop of the page contents? I have a table with records and a div that sits ontop of the table which moves to the vertical position of that record which contains sub-records upon the click. These sub-records in the div also have a level of sub-records themselves and I wish to put another div ontop of the first displaying info about them. Would that be too ridiculous?
gracias de antemano,

PHP creating a while loop that is dependent on multiple variables that are independent of one another?
|
I'm stumped on this and my searches aren't turning up anything relevant.. I need to do a while loop that will continue if either of 2 variables are true... as far as I can tell you can't do a "while ($var = '' and $var2 = ''); so I tried this, basically I figured I could just set 2 different if statements so that it would change the variable "continue" if it went past 4 iterations (if $i >= 4), however this just gives an infinite loop:
function whiletest ()
{
$i = 1;
do {
echo 'output' ;
if ($status != 'true') {
$continue = 1 ;
}
if ($i >= 4) {
$continue = 2 ;
}
$i++ ;
} while ($continue = 1 );
}

Best way to implement user verifcation
|
we are launching a classified portal. We want to be able to add a verification sticker, badge...to ensure safe transactions. What would be the best way to implement such a structure.
If a user is banned (scamming, spamming...) how could we make it difficult/tedious for them to create a new account ?
Thanks for your help, we are not looking for a ready made solution, but more towards general aspects and guidelines.

Controlling events on Apple Ipad's Safari
|
well, this will be a tough one. I think i have exhausted all my options, let's see if you can come up with something better.
I have a horizontal carousel and am using touchstart, touchmove, touchend to control it. For the sake of this example, the html structure is something like:
<div>
<ul id="strip">
<li><a>...</a></li>
<li><a>...</a></li>
...................
</ul>
</div>
I have separated my eventhandlers to behave a bit differently from mouse to touch events, so, thinking only of touch, i have:
var strip = document.getElementById('strip');
strip.addEventListener('touchstart', touchStartHandler);
document.addEventListener('touchmove', touchMoveHandler);
document.addEventListener('touchend', touchEndHandler);
I want the horizontal scrolling to work even if the user has his finger outside my strip, so i attached the touchmove and touchend event to the document.
At first, i thought it would be natural to, while the user was scrolling my carousel, for the browser to stay put, so my touchMoveHandler looked something like:
function touchMoveHandler(evt){
evt.preventDefault();
...................
}
... this way, the browser wouldn't pan vertically when the user's finger positioned varied in the Y axis. Our usability guy, thinks otherwise, and i actually agree with him now. He wants the browser to respond normally, unless the movement of the finger is totally or near perfectly horizontal.
Anyway, this is probably too much information, so i am going to detail my actual problem now. This is a snippet of the prototype i'm working on as a proof of concept:
var stopY, lastTime, newTime;
var touchStartHandler(evt){
...
stopY = true;
lastTime = new Date();
...
};
var touchMoveHandler(evt){
...
//this following code works like a setInterval, it turns stopY on and off every 1/2 sec
//for some reason, setInterval doesn't play well inside a touchmove event
newTime = new Date();
if(newTime - lastTime >= 500){
this._stopY = !this._stopY;
lastTime = newTime;
}
...
if(stopY){
evt.preventDefault();
}
...
}
I am absolutely sure this code is pristine, i debugged it with console logs and everything is doing what it's supposed to do except for the commuting of the browser panning throught the stopY variable.
If i run the code starting with stopY = true, there is no browser panning, if i start with stopY = false, the browser pans as expected. The problem is that i would expect this behaviour to change every half a second and it doesn't.
I hope i didn't complicate this too much for you, but this is really specific.
Thanks for your time and for your help

Get total size of attached files on all list items in SharePoint 2007with PowerShell v2.0
|
Using Powershell I have to get the total size of all attached files on all list items for a generic list. I tryed to use the function below but this will display the total length of names for the attached files.
function GetListSize($List, $Web)
{
[long]$listSize = 0
foreach ($listItem in $List.Items)
{
$listItemAttachments = $listItem.Attachments
foreach($file in $listItemAttachments)
{
$listSize += $file.Length
}
}
$totalInMb = ($listSize/1024)/1024
$totalInMb = "{0:N2}" -f $totalInMb
return $totalInMb
}
I can do this using c# (http://mykiavash.wordpress.com/2011/05/02/how-to-get-size-of-sharepoint-2010-list-item-attachment/) code but no ideea using PowerShell script. Do you have any ideea ?
