d18201 | test | The question basically drill downs to when should I make a method static. The answer is simple- when your method has a very specific task and does not change the state of the object.
Something like a utility method, say add(int a, int b) which simply returns a+b. If I need to store the value a+b for later use for the object, static method is strictly no-no (you will not be able to store a non static variable in a static method). But if we are dealing with some action which is independent of state of the object, static is the answer.
Why are we giving preference to static if it is independent of state of object?
*
*Memory- static method will only have one copy, irrespective of the actual number of object.
*Availability- Method is available even if you don't have single object
Ofcourse the downside is that we are keeping a copy of method even if we do not use it at all (if it was non-static and no object was created, we would have saved this space). But this is of lower weight than the advantages mentioned above.
As the method we are discussing here (makeText), does not need to maintain a state for later use, the best way to go is static method.
--Edit--
The answer mentioned above is more generic as to when we should use static and when non-static, let me get specific to Toast class.
Toast class gives us 2 ways to create a Toast object (Refer http://developer.android.com/reference/android/widget/Toast.html)
*
*makeText(Context context, CharSequence text, int duration) which returns a Toast object which the values assigned.
*Normal way, use new Toast(context) to create an object, then set values as required.
If you use method 1, you are saying something like Toast.makeText(context, text, duration).show(); and we are done. I use this method all the time.
Method 2 is used only for a specific case, from http://developer.android.com/guide/topics/ui/notifiers/toasts.html
Do not use the public constructor for a Toast unless you are going to
define the layout with setView(View). If you do not have a custom
layout to use, you must use makeText(Context, int, int) to create the
Toast.
@CFlex, If I got your question properly, I guess you just want to know why we have Toast.makeText(context, text, duration) returning a Toast object, when the same thing could have been done by a constructor.
Whenever I look at something like ClassName.getObject returning object of class, I think about singleton pattern. Well, in this case we are not exactly talking about singleton, I would like to assume that makeText returns same object always (to save creation of N objects), otherwise it is just a fancy thing developed by Android team.
A: One rule: Ask yourself "Does it make sense to call this method, even if no object has been constructed yet?" If so, it should definitely be static.
Remember that objects live in memory and they are created for certain jobs. Static methods are available for all the objects in a class and it is not necessary to create an object to use them.
So there is no reason to create an object Toast to be able to access the method makeText, when you can access it as a static method (more elegant and compact)
A: As far as I know:
That's because we don't wish to hold an instance of the object toast, which would require an amount of memory persistently used until cleaned by the GarbageCollector.
And that it always have access to being displayed, so it is not required by your application to have any set of permissions. | unknown | |
d18202 | test | In this answer I assume that your direct parent is always in a row above your own as it is what your expected output and your diagramm suggests.
With this hypothesis, we can, for each row, take the closest row with a level below the row :
import pandas as pd
data={"Symbol":["A", "A01", "A01B", "A01B 1/00", "A01B 1/02", "A01B 1/022", "B"], "level":[2,4,5,7,8,9,2]}
df=pd.DataFrame(data=data)
df['Parent'] = ''
for index, row in df.iterrows():
# We look at the potential parents
potential_parents = df.loc[df.index.isin([x for x in range(index)]) & (df['level'] < row['level']), 'Symbol']
# And we take the last one as our parent
if len(potential_parents) == 0:
df.loc[index, 'Parent'] = ''
else:
df.loc[index, 'Parent'] = potential_parents.iloc[-1]
Output :
Symbol level Parent
0 A 2
1 A01 4 A
2 A01B 5 A01
3 A01B 1/00 7 A01B
4 A01B 1/02 8 A01B 1/00
5 A01B 1/022 9 A01B 1/02
6 B 2
A: Here's another method. GetParent() returns a function that keeps track of the most recent symbol for each level and returns the parent of the current level. Using it in pandas.apply() creates a column with the parent symbols.
def GetParent():
# 0 1 2 3 4 5 6 7 8 9 10
hierarchy = [0, 0, 0, 0, 2, 4, 0, 5, 7, 8, 9]
parent = [' ']*11
def func(row):
#print(row)
symbol,level = row[['SYMBOL', 'level']]
parent_level = hierarchy[level]
parent_symbol = parent[parent_level]
parent[level] = symbol
return pd.Series([parent_symbol], index=['parent'])
return func
# create a column with the parents
parents = df.apply(GetParent(), axis=1)
df = pd.concat([df, parents], axis=1)
df
Output:
SYMBOL level na ao parent
0 A 2 True False
1 A01 4 True False A
2 A01B 5 True False A01
3 A01B 1/00 7 False False A01B
4 A01B 1/02 8 False False A01B 1/00

d18203 | test | With your current code, you are trying to filter patterns with patterns.
Using the WHERE Clause with variables would be the best approach.
Match the pattern first and then filter on the desired property.
You could use the following Query to match users based on their postcode:
MATCH (p:Person)-[:HasPostcode]->(pc:Postcode)
WHERE pc.value='LA2 0RN'
RETURN p, pc
If you want to use an OR condition and find matches for Postcode or Name:
MATCH (f)<-[:HAS_FIRST_NAME]-(p:Person)-[:HasPostcode]->(pc)
WHERE pc.value='LA2 0RN' OR f.value='Jerry' OR f.value='Tom'

d18204 | test | I think you need an architect to re-design your solution to lift in the cloud. It is good time to check whether you want to move to managed products or would prefer just the same in the cloud.
Talking about the products:
*
*Rabbit QM should be replaced with Pub/Sub, which fits pretty good. If you would like to keep using RabbitMQ here. PubSub should be the best choice if you want to move most of your solution to the Google Cloud, and in the long term could bring more benefits in the Gooogle Cloud ecosystem.
*Dataflow is a good batch processor. Here is an example of PubSub - Dataflow: Quickstart: stream processing with Dataflow. There are Google-Provided batch templates or you can create one: traditional or Flex.
Don't rush and pick a solution. It is well worth to check all your business and technical requirements and explore the benefits of each product (managed or not) of the Google Cloud. The more detailed your requirements are, the best you can design your solution.
A: Google Cloud offers, today, only one workflow manager named Cloud Composer (based on Apache Airflow project) (I don't take into account the AI Platform workflow manager (AI Pipeline)). This managed solution allow you to perform the same things than you do today with Celery
*
*An event occur
*A Cloud Function is called to process the event
*The Cloud Function trigger a DAG (Diagram Acyclic Graph - a workflow in Airflow)
*A step in the DAG runs a lot of sub process (Cloud Function/Cloud Run/anything else) wait the end, and continue to the next step...
2 warnings:
*
*Composer is expensive (about $400 per month, for the minimal config)
*DAG are acyclic. no loops are authorized
Note: A new workflow product should come on GCP. No ETA for now, and at the beginning the parallelism want be managed. IMO, this solution is the right one for you, but not for short term, maybe in 12 months
About the MQTT queue, you can use PubSub, very efficient and affordable.
Alternative
You can build your own system following this process
*
*An event occur
*A Cloud Function is called to process the event
*The cloud function create as many PubSub message as batched are required.
*For each message generated, you write an entry into Firestore with the initial event, and the messageId
*The generated messages are consumed (by Cloud Function, Cloud Run or anything else) and at the end of the process, the Firestore entry is updated saying that the sub process has been completed
*You plug a Cloud Function on Firestore event On Write. The function checks if all the subprocess for an initial event are completed. If so, go to the next step...

If you want to regularly increment $i variable:

A: try this :
$temp = $i+1;
$x = 'icon'.$temp;
You are getting wrong answer because of "Operator Precedence",
Ref this link : http://php.net/manual/en/language.operators.precedence.php
Here see the line : left + - . arithmetic and string

To solve it either use the method i mentioned above or hsz answer
ie : $x = 'icon'.($i+1);
A: Operator Precedence explains why this is happening.
You can use brackets:
$x = 'icon'.($i+1);
This should do the job.

d18221 | test | So, in that case does it make sense to have multiple methods with different signatures, or is that not a factory pattern at all?
It doesn't make any sense to have a factory with specific methods. If your client code has to decide which specific method should it use, why wouldn't it call the specific car's constructor directly? In your example, factory methods would merely be wrappers over specific constructors.
On the other hand having a single factory method that is called with an enum gives your client a chance to decide dynamically which car should it create, the decision could for example be based on a database query.
There are some possible ways around your current approach.
One option would be to have a hierarchy of classes that represent constructor parameters. You don't even need the enum then because the parameter type is enough to infer which specific car should be created:
public abstract class CarCreationParams { }
public class FordCreationParams : CarCreationParams
{
public Engine engine;
}
...
public class CarFactory
{
public Car GetCar( CarCreationParams parms )
{
if ( parms is FordCreationParams )
return new Ford( ((FordCreationParams)parms).engine );
...
Another option would be to think whether you really need your Fords to be created with external engines (aggregation) or rather they own their engines (composition). In the latter case, you would expose parameterless constructors to your specific car types:
public class Ford : Car
{
public Engine engine;
// car is composed of multiple parts, including the engine
public Ford()
{
this.engine = new FordEngine();
}
which makes the implementation of the factory much easier.
A: No that is not a good example of factor pattern. Rather if your Car class is dependent on different types of Components you can have factories for those too. E.G For Car and Engine you can have like:
public interface ICar
{
IEngine Engine { get; set; }
}
public class Mustang : ICar
{
private IEngine _engine = EngineFactory.GetEngine(EngineType.Mustang);
public IEngine Engine
{
get { return _engine; }
set { _engine = value; }
}
}
public class CarFactory
{
public ICar GetCar(CarType carType)
{
switch (carType)
{ case CarType.Ford: return new Mustang(); }
}
}
Similarly for Engine
public interface IEngine { }
public class MustangEngine : IEngine
{
}
public class EngineFactory
{
public static IEngine GetEngine(EngineType engine)
{
switch (engine)
{ case EngineType.Mustang: return new MustangEngine(); }
}
}
A: In case you need different parameters for object creation(batteries for Tesla or Engine for Ford) you can choose between different solutions:
- pass all of these parameters while creating a factory - it will be specific factory for all types of car with such available details;
class SpecificCarFactory
{
public SpecificCarFactory(IList<Battery> batteries, IList<Engine> engines)
{
//save batteries etc into local properties
}
public Car GetCar(CarType carType)
{
switch(carType)
{ case CarType.Ford: return new Mustang(_engines.First()); }
}
}
*
*encapsulate parameters into class object and get them from factory method parameter;
class CarFactory
{
public Car GetCar(CarDetail carDetail) //where CarDetails encapsulates all the possible car details
{
switch(carDetail.type)
{ case CarType.Ford: return new Mustang(carDetail.Engine);//just an example
}
}
}
A: Yes, It is factory pattern.
factory pattern says to create factories of Object but let subclass decide the way to instantiate the object .
This is true in your case your deciding based on type of Enum | unknown | |
d18222 | test | That is... odd. I can't repro it here, so I'm guessing it is something specific to Blazor. I've checked what the code does in the "regular" frameworks, and at least for me it seems to do the right things - using UnaryValueTaskAsync<Customer, Customer>() and UnaryValueTaskAsync<Empty, CustomerResultSet>(), which is what I would expect. I've improved the exception handling in that code path, to at least give us a clue what it is trying to do, so my suggestion is:
*
*update to protobuf-net.Grpc version >= 1.0.119 (I'll get it deployed as soon as CI finishes)
*retry, and let me know exactly what it says now
Alternatively, if you have a minimal repro including the blazor bits on, say, a GitHub repo, I can happily take a look there.
(tip: I try to keep an eye on both Stack Overflow and GitHub, but GitHub is probably more appropriate for this kind of question - I'd happily say that this is a bug, so: https://github.com/protobuf-net/protobuf-net.Grpc/issues)

A: Unless you specify otherwise, function/method arguments are pass-by-value, meaning you get a copy of them inside the function. If you want the function to change the variable that was passed to it, you need to pass-by-reference. As described here:
By default, function arguments are passed by value (so that if the
value of the argument within the function is changed, it does not get
changed outside of the function). To allow a function to modify its
arguments, they must be passed by reference.
To have an argument to a function always passed by reference, prepend
an ampersand (&) to the argument name in the function definition:
Note the ampersand before $array in the doc page for sorting functions like asort() and ksort():
bool asort ( array &$array [, int $sort_flags = SORT_REGULAR ] )
bool ksort ( array &$array [, int $sort_flags = SORT_REGULAR ] ) | unknown | |
d18229 | test | WebAudio should be able to start audio very precisely using start(time), down to the nearest sample time. If it doesn't, it's because the audio data from decodeAudioData doesn't contain the data you expected, or it's a bug in your browser.
A: Looks like when you call keyPressed, you want to trigger both songs to start playing. One immediately, and the other in 7.5 seconds.
*
*The function to play the songs is soundObj.play and it needs to take an additional argument, which is the audioContext time to play the song. Something like: soundObj.play = function(volumeVal, pitchVal, startTime) {...}
*The function keyPressed() block should look something like this:
harp1.play(.5, 2, 0);
harp2.start(1, 1, audioContext.currentTime + 7.5);
audioContext.resume();
audioContext.resume() starts the actual audio (or rather starts the audio graph timing so it does things you've scheduled) | unknown | |
d18230 | test | A few things:
*
*Use the grid array to store the on\off blocks of the screen. It only gets read when the screen is resized and needs a full redraw
*When a new rectangle is turned on, draw the rectangle directly in the event handler and update the grid array. There is no need to redraw the entire screen here.
*In the resize event, reset the screen mode to the new size then redraw the entire screen using the grid array. This is the only time you need to do a full redraw.

d18233 | test | Fixed fiddle
Check the DOM in your browser console you can see that the input is already inside the div, you should just adjust CSS, check example bellow.
Hope this helps.
var vertical_slider = document.createElement('div');
vertical_slider.id = 'vertical_slider';
var osa_y_panorama = 0.6;
var range_pitch = document.createElement("input");
range_pitch.setAttribute("type", "range");
range_pitch.style.webkitTransform = "rotate(90deg)";
range_pitch.style.mozTransform = "rotate(90deg)";
range_pitch.style.oTransform = "rotate(90deg)";
range_pitch.style.msTransform = "rotate(90deg)";
range_pitch.style.transform = "rotate(90deg)";
range_pitch.min = "0";
range_pitch.max = "218";
range_pitch.step = "0.6";
range_pitch.defaultValue = osa_y_panorama;
vertical_slider.appendChild( range_pitch );
document.body.appendChild( vertical_slider );
#vertical_slider
{
float: left;
width: 40px;
height: 218px;
border: 1px solid blue;
}
input{
position: relative;
top:93px;
right: 83px;
width:200px;
}
A: The problem come from your css rotation to the input, if you check the DOM, your element is inside but the rotation make it look outside.
You can use this css to hot fix it :
input {
position: relative;
right: 70px;
top: 100px;

Also you can take a look at uniswap API ; https://docs.uniswap.org/protocol/V2/reference/API/entities
A: If you want it to be compatible across multiple chains and multiple DEXs, the easiest way I could think of is to call the router by using the method getAmountsOut.
router.methods.getAmountsOut(amountIn, [inAddress, outAddress]).call()
amountIn would be 1 * Math.pow(10, inAddress token decimals)
inAddress is WBTC address
outAddress is USDC address
The output will be:
100000000,22397189858
Output[0] is amount in. Output[1] is amount out. You then have to divide that by
(1 * Math.pow(10, out address decimal), where you will get WBTCprice: 22397.189858
The only caveat of doing this method is that you need to know the stable pair that exist on that dex. Some dex may use WBTC/USDT, some may use WBTC/USDC. | unknown | |
d18238 | test | This is frequently a problem with beginners when they fail to validate the JS written. Whatever editor you use, try using a JS validator to validate whether JS has been written correctly.
In this case, I believe you forgot to use a bracket after completing your getJSON function.
$.getJSON(
'http://api.fixer.io/latest',
function(data) {
// Check money.js has finished loading:
if ( typeof fx !== "undefined" && fx.rates ) {
fx.rates = data.rates;
fx.base = data.base;

// If not, apply to fxSetup global:
var fxSetup = {
rates : data.rates,
base : data.base
}
}
); //This bracket is missing in your code
For JS validation, use http://www.jslint.com/

d18239 | test | Here's an answer addressing iterkeys vs. viewkeys here: https://stackoverflow.com/a/10190228/344143
Summary (with a little backstory): view* methods are a live view into the data (that will update as it updates), whereas iter* and just-plain * are more like snapshots.
The linked answerer suggests that while the view*-flavored methods may have a minor performance edge as well, there may be compatibility issues with the backport, and recommends continuing to use iter*/* under Python 2.
My take: if you want a live view and you're under Python 2, use view*; if you just want to whip through the set of keys/values/items once, use iter*; if you want to hang on to a snapshot of k/v/i for a bit (or iterate in some non-linear fashion), use *. Let the performance slide until you pick it up in an inner loop. | unknown | |

d18241 | test | I just briefly looked at the Github project you referenced, and I wanted to throw in my $0.02, for whatever it's worth -
Breeze.js is responsible for taking care of client side caching for you. The idea is to not have to worry about what the back-end is doing and simply make a logical decision on the client on whether to proceed and hit the server for data again. If you don't need to refresh the data, then never hit the server, just return from Breeze's cache.
The project you are referencing seems to do both - server side and client-side caching. The decision of caching on the server is one not to be taken lightly, but this project seems to handle it pretty well.
The problem is that you are trying to mix two libraries which, at best, conflict in the area of what their concerns are. There may be a way to marry the two up, but at what cost? Why would you need to cache on the server that which is already cached on the client? Why cache on the client if you plan to cache the exact same data on the server?
The only reason I can think of is for paging of data (looking at a subset of the whole) and wanting to see the next data set without having to hit the server again. In that case, your query to the server should not match the original anyway and therefore one would expect that you need to customize the two solutions to do what you are asking for.
In general that project seems to ignore queryString parameters, from what I can tell, to support JSONP so you should have no problem coming up with a custom solution, if you still think that is necessary. | unknown | |

d18243 | test | Here's a slight modification of your code that might help you.
The main points:
*
*You can use getline() instead of fscanf(). fscanf() can be used to read line-by-line, but it needs an explicit check for the end of line condition. getline() does this automatically.
*As kaylum pointed out, it's necessary to rewind() the file pointer back to the beginning of the file after counting the number of lines.
#include <omp.h>
#include <stdio.h>
#include <stdlib.h>
void countAnagrams(char* fileName);
void main ()
{
char *fileNames[] = {"AnagramA.txt","AnagramB.txt","AnagramC.txt","AnagramD.txt"};
countAnagrams(fileNames[0]);
countAnagrams(fileNames[1]);
countAnagrams(fileNames[2]);
countAnagrams(fileNames[3]);
}
void countAnagrams(char* fileName)
{
int anagramCount = 0;
int ch, lines = 0;
//Count number of lines in file
FILE *myfile = fopen(fileName, "r");
do
{
ch = fgetc(myfile);
if (ch == '\n')
lines++;
} while (ch != EOF);
rewind(myfile);
char *contents[lines];
int i = 0;
size_t len = 0;
for(i = 0; i < lines; i++)
{
contents[i] = NULL;
len = 0;
getline(&contents[i], &len, myfile);
}
fclose(myfile);
printf("%.12s\n",fileName);
printf("number of lines: %d\n", lines);
printf("first thing: %s\n", contents[0]);
printf("last thing: %s\n", contents[lines-1]);
}
A: I think that the problem is char contents[lines] and then fscanf(myfile,"%s",contents[i]) and the printf-s after. contents[i] is char type, and you want to read an array of chars into one char. contents needs to be declared as char* contents[lines] to be able to read a char array into contents[i]. | unknown | |
d18244 | test | You sign with your private key. Signature is proof of origin, it proves that you were in possession of the private key therefore the data must be from you, and the data was not altered.
You encrypt with the destination public key. This is to ensure that only the destination can decrypt it.
As you see, the signature and encryption serve different purposes.
A: Signing is putting your signature on a letter, and encrypting is putting the letter in an envelope. The envelope keeps other people from reading the letter. The signature proves that you wrote the letter.
Additionally, you sign and then encrypt, in that order, because if you instead put the letter in the envelope first, and then sign the envelope, this doesn't really prove that you wrote letter. You could argue in front of a judge that you didn't get to see the letter before the envelope was sealed.
Finally, you should not use the same key for both signing and encrypting. There are cryptographic reasons, but another, simpler reason is that the key that you use for encrypting can be held in escrow by other people (for example, the company you work for) to have access to the contents of all of your envelopes if needed, but the key you use for signing should only be given to people you would trust to legally sign in your place, as if a power of attorney. | unknown | |

d18249 | test | Try File.seek and File.rawRead. They work like their C counterparts, but rawRead determines the read count from the size of the output buffer you hand it. | unknown | |
d18250 | test | I think the real problem is that you are confused about number representations and text renderings of numbers. Here are some key facts that you need to understand:
*
*The byte type is the set of integral values from -128 to +127.
*All integral types use the same representation (2's complement). The difference between the different types is their ranges.
*When you "see" a number, what you are seeing is a rendering of the number into a sequence of characters. There are MANY possible renderings; e.g. the number represented in memory as 00101010 (42) can be rendered as "42" or "+42" or "0x2a" or ... "forty two".
*The default format for rendering a byte, short, int and long is the same; i.e. an optional minus sign followed by 1 or more decimal digits (with no zero padding). If you want to see your numbers formatted differently, then you need to do the formatting explicitly; e.g. using String.format(...).
So to pull this together, if you want the bytes to look like 0x00 and 0x01 when you output or display them, you need to format them appropriately as you output / display them. In your example code, I doubt that there is anything wrong with the numbers themselves, or with the loop you are using to populate the array.
A: You are confusing the string representation of the value with the value itself. A value can be represented as binary, decimal, or hex, but it is still the same value.
If you want to use your integer to initialise a byte array, you just need to cast your integer value to a byte value as follows:
arr[i] = (byte) i;
A: new byte[]{0x00}
is actually equivalent to
new byte[]{0}
The 0x00 notation is just an alternative way to write integer constants, and if the integer constant is in the range -128 to 127, then it can be used as a byte.
If you have an existing integer variable that you want to use, and its value is in the range -128 to 127, then you just have to cast it:
int i = 1;
new byte[]{(byte)i};
A: You want
new byte[]{(byte)i}
How you print this array is another matter. Look up printf in the API reference.
A: I would just like to note that 0 is NOT the same thing as 0x00. If i were to use:
ColorChooserOutputText.append(Integer.toHexString(list[i].getRed()));
ColorChooserOutputText.append(Integer.toHexString(list[i].getGreen()));
ColorChooserOutputText.append(Integer.toHexString(list[i].getBlue()));
and wanted to return the color, Purple it would return: ff0cc Which would be fine if I were just using Java. But if you are going between Java and something that had format specific needs ff0cc would not produce purple.. ff00cc is actually purple.
//Declare some variables.
Color HexColor = JButton1.getBackground();
String MyRValue = null;
String MyGValue = null;
String MyBValue = null;
//Get Hex Value
MyRValue = Integer.toHexString(HexColor.getRed());
MyGValue = Integer.toHexString(HexColor.getGreen());
MyBValue = Integer.toHexString(HexColor.getBlue());
//Make sure to keep both 0's
MyRValue = ("00"+MyRValue).substring(MyRValue.length());
MyGValue = ("00"+MyGValue).substring(MyGValue.length());
MyBValue = ("00"+MyBValue).substring(MyBValue.length());
//Format your HexColor to #00ff00, #000000, #ff00ee
JTextArea1.append("#");
JTextArea1.append(MyRValue+MyGValue+MyBValue);
JTextArea1.append(", ");
A: String.Format ("%02x") is your friend :)

d18251 | test | bower will download the entire package using Git.
Your package must be publically available at a Git endpoint (e.g., GitHub). Remember to push your Git tags!
This means that bower will actually download the entire repository/release for you to use in your ASP project. I've tested this with bootstrap and jQuery. These repositories can contain many many files so including them into the .csproj file will clutter your project file and may not be ideal.
This can be compared to using nuget packages where we are only referencing external packages in the packages.config file but we do not include the dll and other assemblies into the project. This leads me to think that bower_components should indeed not be included in the project; this makes no difference to usage as you can still reference the packages and use the files. | unknown | |
d18252 | test | Well you can 3 options:
*
*Create a layout with UIIImageViews and UITextView
*Use HTML and UIWebView
*NSAttributedString and draw it on a view with CoreText
A: That's almost certainly laid out in an UIWebView, with the styling on the image set to "float: left" with margin settings that hold the text off from the edge of it but let it wrap around it.
Here's a little tutorial about it: http://www.tizag.com/cssT/float.php
Note that this is about the HTML and CSS content to feed the UIWebView, not anything iOS-ish.
A: You arrange UIImageViews and UITextViews in the way you want them by setting their frames. Then assign images to the imageViews and text to the textViews. | unknown | |

function myFunction() {
var cb = document.getElementById('menu-open');
var logo = document.getElementById('logo');
if (cb.checked) {
logo.setAttribute("class", "newClass");

d18254 | test | Just for testing i have replicated, and it works fine as expected
A: Actually you can't do that by overlaying the dialog, you'll need to rely in DAM Metadata Schemas to achieve that - https://experienceleague.adobe.com/docs/experience-manager-64/assets/administer/metadata-schemas.html?lang=en
From there, and if you want to persist these definitions in your code baseline, you can refer to the location where it gets stored - /conf/global/settings/dam/adminui-extension/metadataschema

d18255 | test | InstanceProfileCredentialsProvider retrieves credentials as needed; a client using it should never see a credentials timeout exception.
This implies that either (1) you are explicitly setting instance profile credentials on the client that is timing out, or (2) there is something else in the provider chain that is providing limited-time credentials.
Or, I suppose, you might be using an extremely old version of the SDK. I don't know at what point they added automatic refresh; according to git blame, the fetcher variable was last changed 13 months ago. But I've been using instance credentials with long-running processes for much longer than that.
A: This article may help you.
If you really need to get a new credentials, the following example shows pseudocode for how to use temporary security credentials if you're using an AWS SDK:
assumeRoleResult = AssumeRole(role-arn);
tempCredentials = new SessionAWSCredentials(
assumeRoleResult.AccessKeyId,
assumeRoleResult.SecretAccessKey,
assumeRoleResult.SessionToken);
s3Request = CreateAmazonS3Client(tempCredentials);

Selection.FormatConditions(Selection.FormatConditions.Count).SetFirstPriority
With Selection.FormatConditions(1).Interior

End With
I know there's a way to string it all together... I'm just not sure how. There don't even have to be multiple columns... That's just how I knew how to get it to work.
A: You're on the right track with your VBA, but you're trying to use formula syntax in VBA code, and that's not going to work.
Change this:
"=IF(AND((RC[-8]>1),(RC[-1]=1),(RC[-7]>0)),""Yellow""," & _
"IF(AND((RC[-8]>1),(RC[-1]=1),(RC[-7]=0)),""Red""," & _
"IF(AND((RC[-8]>1),(RC[-1]>1),(RC[-7]>0)),""Blue""," & _
"IF(AND((RC[-3]=""Yes""),(RC[-7]>0)),""Blue""," & _
"IF(AND((RC[-3]=""No""),(RC[-7]>0)),""Red""," & _
"IF(RC[-7]<0,""Orange""," & _
"IF(RC[-7]=0,""Red"",""Next"")))))))"
To this:
Dim cel as range
offset(row,col)
set cel = ActiveCell
if cel.offset(0,-8) > 1 and cel.offset(0,-1) = 1 and cel.offset(0,-7) > 0 then
cel.interior.color = vbYellow
elseif cel.offset(0,-8) > 1 and cel.offset(0,-1) = 1 and cel.offset(0,-7) = 0 then
cel.interior.color = vbRed
elseif cel.offset(0,-8) > 1 and cel.offset(0,-1) > 1 and cel.offset(0,-7) > 0 then
cel.interior.color = vbBlue
elseif ucase(cel.offset(0,-3)) = "YES" and cel.offset(0,-7) > 0 then
cel.interior.color = vbBlue
elseif ucase(cel.offset(0,-3)) = "NO" and cel.offset(0,-7) > 0 then
cel.interior.color = vbRed
elseif cel.offset(0,-7) < 0 then
cel.interior.color = vbOrange
elseif cel.offset(0,-7) = 0 then
cel.interior.color = vb.Red
End If
Note:
*
*vbOrange may not be a predefined color. You may have to specify the RGB you want to get there. This was done to get you going.
*set cel = ActiveCell is most likely not what you really want, but you didn't specify any code around it, so you'll have to figure out how to assign this properly yourself.
*Using this code, I think you should be able to eliminate the use of multiple columns now that you have the proper syntax for VBA instead of a formula. | unknown | |
d18258 | test | QProcess is derived from QIODevice, so I would say calling close() should close the file handle and solve you problem.
A: I cannot see the issue, however one thing that concerns me is a possible invocation overlap in getMemoryUsage() where it's invoked before the previous run has finished.
How about restructuring this so that a new QProcess object is used within getMemoryUsage() (on the stack, not new'd), rather than being an instance variable of the top-level class? This would ensure clean-up (with the QProcess object going out-of-scope) and would avoid any possible invocation overlap.
Alternatively, rather than invoking /usr/bin/free as a process and parsing its output, why not read /proc/meminfo directly yourself? This will be much more efficient.
A: First I had the same situation with you. I got the same results.
I think that QProcess can not handle opened pipes correctly.
Then, instead of QProcess, I have decided to use popen() + QFile().
class UsageStatistics : public QObject {
Q_OBJECT
public:
UsageStatistics(){
timer = new QTimer(this);
connect(timer, SIGNAL(timeout()), this, SLOT(getMemoryUsage()));
timer->start(1000); // one second
}
virtual ~UsageStatistics() {}
private:
QFile freePipe;
FILE *in;
public slots:
void getMemoryUsage() {
if(!(in = popen("/usr/bin/free", "r"))){
qDebug() << "UsageStatistics::getMemoryUsage() <<" << "Can not execute free command.";
return;
}
freePipe.open(in, QIODevice::ReadOnly);
connect(&freePipe, SIGNAL(readyRead()), this, SLOT(parseResult()) );
// OR waitForReadyRead() and parse here.
}
void parseResult(){
// Parse your stuff
freePipe.close();
pclose(in); // You can also use exit code by diving by 256.
}
}
A: tl;dr:
This occurs because your application wants to use more resources than allowed by the system-wide resource limitations. You might be able to solve it by using the command specified in [2] if you have a huge application, but it is probably caused by a programming error.
Long:
I just solved a similar problem myself. I use a QThread for the logging of exit codes of QProcesses. The QThread uses curl to connect to a FTP server uploads the log. Since I am testing the software I didn't connect the FTP server and curl_easy_perform apparently waits for a connection. As such, my resource limit was reached and I got this error. After a while my program starts complaining, which was the main indicator to figure out what was going wrong.
[..]
QProcessPrivate::createPipe: Cannot create pipe 0x7fbda8002f28: Too many open files
QProcessPrivate::createPipe: Cannot create pipe 0x7fbdb0003128: Too many open files
QProcessPrivate::createPipe: Cannot create pipe 0x7fbdb4003128: Too many open files
QProcessPrivate::createPipe: Cannot create pipe 0x7fbdb4003128: Too many open files
[...]
curl_easy_perform() failed for curl_easy_perform() failed for disk.log
[...]
I've tested this by connecting the machine to the FTP server after this error transpired. That solved my problem.

Also, note that MoveTo only works on the same logical drive. If that's not enough for you, you will need to add your own copy+delete method for moving files accross drives. | unknown | |
d18260 | test | I don't think this will work in Javascript since objects are written like JSON and thus properties will be undefined or null but not throw an error.
The solution will be writing a native getter/setter.
var obj = {

obj.vars[index] = value;
},
get: function(index) {
if (typeof(vars[index]) == "undefined") {
throw "Undefined property " + index;

A: There is no reliable getter/setters in javascript right now. You have to check it manually. Here's a way to do that:

d18263 | test | Can a stack allocated buffer be accessed through C++?
Yes.
From the type-system perspective there is no difference between statically allocated, stack allocated, or heap allocated: the C signature only takes pointer and size, and cares little where that pointer points to.
Is this safe?
Most likely.
As long as the C function is correctly written and respects the bounds of the buffer, this will be safe. If it doesn't, well, that's a bug.
One could argue that it's better to have a heap-allocated buffer, but honestly once one starts writing out of bounds, overwriting arbitrary stack bytes or overwriting arbitrary heap bytes are both bad, and have undefined behavior.
For extra security, you could use a heap allocated nested between 2 guard pages. Using OS specific facilities, you could allocate 3 contiguous OS pages (typically 4KB each on x86), then mark the first and last as read-only and put your buffer in the middle one. Then any (close) write before or after the buffer would be caught by the OS. Larger jumps, though, wouldn't... so it's a lot of effort for a mitigation.
Is your code safe?
You most likely need to know how many bytes were written, so using a null pointer is strange.
I'd expect to see:
let mut written: size_t = 0;
let written_size = &mut written as *mut _;
And yes, that's once again a pointer to a stack variable, just like you would in C.
A note on style. Your Rust code is unusual in that you use fully typed variables and full paths, a more idiomatic style would be:
// Result is implicitly in scope.
pub fn receive(&mut self, f: &dyn Fn(&[u8])) -> Result<(), &str) {
let mut buffer = [0u8; MAX_BYTES_TRANSPORT];
let mut written: size_t = 0;
let written_size = &mut written as *mut _;
// Safety:
// <enumerate preconditions to safely call the function here, and why they are met>
let result = unsafe {
openvpn_client_receive_just(
buffer.as_mut_ptr(), buffer.len(), written_size, self.openvpn_client)
};
translate_openvpn_error(result)?;
let buffer = &buffer[0..written];
f(buffer);
Ok(())
}
I did annotate the type for written, to help along inference, but strictly speaking it should not be necessary.
Also, I like to preface every unsafe call I make with the list of pre-conditions that make it safe, and for each why they are met. It helps me audit my unsafe code later on. | unknown | |

d18265 | test | Your code needs to run in a new thread. Look into the System.Threading namespace for instructions and examples of how to create a new thread. Essentially, you create the thread
Here is an example from one of my old test programs.
Thread thdOneOfTwo = new Thread(new ParameterizedThreadStart(TextLogsWorkout.DoThreadTask));
In the above example, TextLogsWorkout.DoThreadTask is a static method on class TextLogsWorkout, which happens also to contain the above statement.
You have the option of giving each thread a name, and of using a WaitHandle that it can signal when it has completed its assignment. Both are optional, but you must execute the Start method on the instance.
Be aware that you are entering the world of multi-threaded programming, where many hazards await the unwary. If you aren't already, I suggest you read up on mutexes, wait handles, and the intrinsic lock () block.
Of the three, lock() is the simplest way that a single application can synchronize access to a property. Of the other two, WaitHandles and Mutexes are about equal in complexity. However, while a WaitHandle can synchronize activities within a process, a Mutex is a filesystem object, and, as such, can synchronize activities between multiple processes.
In that regard, be aware that if a mutex has a name, as it must if it is to synchronize more than one process, that name must begin with "\?\GLOBALROOT", unless all of them run in the same session. Failure to do this bit me really hard a few years ago. | unknown | |
d18266 | test | Full disclosure: I love the googleVis package.
I see the same behavior you do, even after updating to the latest version of googleVis (not yet on CRAN). I don't know if this is a bug or not; the googleVis documentation for gvisLineChart mentions continuous data, but nothing I tried allows me to plot the X axis as numerical.
You can get clues as to what's happening when you change aspects of your code in generating googleVis charts and graphs if you right-click on the web page that gets displayed with the plot, and choose "View Page Source." This page is where the magic happens, and is the HTML output from the googleVis package.
The problematic line in this case is the one that reads "data.addColumn('string','val1');
In this line, the word 'string' should be 'number', and the val1 values should not be in quotes in the data section.
You can get the results you want, though, by using gvisScatterChart instead:
library(googleVis)
df=data.frame(val1=c(10,13,100), val2=c(23,12,32))
Line <- gvisScatterChart(df, options=list(lineWidth=2, pointSize=0))

d18273 | test | The way I'm handling this is to first use the Web Essentials 2017 extension. This installs the Bundler & Minifier tool, which then adds a bundleconfig.json file to your project. Right-click on this file, go to the Bundler & Minifier menu item and you will see an option in there to Convert To Gulp.
Selecting convert to gulp will create the necessary gulpfile.js and also install the npm packages required for using Gulp. Wait for all of the npm packages to install and you can then right click on gulpfile.js, select Task Runner Explorer and you should be ready to set up Gulp-based tasks. If you see gulpfile.js failed to load message, npm packages may still be installing (check the progress bar on the VS 2017 status bar). Hit the Refresh icon in Task Runner Explorer when all packages are installed and the error should vanish.
There's probably a more manual way to add Gulp support but I find this more automated method ensures all the tooling is wired up to work properly and I don't miss anything.
I gleaned all this information from the awesome Microsoft Docs site, specifically this page on Bundling & Minification. There's also a Using Gulp section in there that may provide additional details for your situation.
https://learn.microsoft.com/en-us/aspnet/core/client-side/bundling-and-minification
A: Microsoft have now added documentation on how to get gulp running:
https://learn.microsoft.com/en-us/aspnet/core/client-side/using-gulp
Make sure you update Visual Studio 2017 to the latest version as it now comes shipped with Node.js, NPM and Gulp (you don't need to pick "Node.js support" when installing Visual Studio for this to work).
Create an npm Configuration File (package.json) in your project folder and edit it to reference gulp:
{
"version": "1.0.0",
"name": "example",
"private": true,
"devDependencies": {
"gulp": "3.9.1"
},
"scripts": {
"gulp": "gulp"
}
}
In the project folder, create a Gulp Configuration File (gulpfile.js) to define the automated process.
Add the following to the post-build event command line for each project requiring gulp support:
cd $(ProjectDir)
call dotnet restore
npm run gulp
To run the tasks in Visual Studio 2017, open the Task Runner Explorer (View > Other Windows > Task Runner Explorer).
Then on the build server just install Node.js and ensure the path to node is added to the environmental path variable then when the build server builds the project gulp will run too!
A: I found the solution here. More information on that part of VS from Mads himself.
You have to force Visual Studio run with your Node.js version:
Go to Tools > Options in Visual Studio 2017
Go to Projects and Solutions > External Web Tools

A: You can kill uwsgi process using standard Linux commands:
killall uwsgi
or
# ps ax|grep uwsgi
12345
# kill -s QUIT 12345
The latter command allows you to do a graceful reload or immediately kill the whole stack depending on the signal you send.
The method you're using, however, is not normally used in production: normally you tell the OS to start your app on startup and to restart it if it crashes. Otherwise you're guaranteed a surprise one day at a least convenient time :) Uwsgi docs have examples of start scripts/jobs for Upstart/Systemd.
Also make sure you don't really run uwsgi as root - that sudo in the command makes me cringe, but I hope you have uid/gid options in your production.ini so Uwsgi changes the effective user on startup. Running a webserver as root is never a good idea. | unknown | |

d18278 | test | Because of the implementation of the fling Method in the ScrollView -
it is sufficient to override the findFocus(), so that it will return this
to prevent the focus from jumping around when scrolling.
@Override
public View findFocus() {
return this;
}
A: It's not scrolling that randomly focuses the EditText. It's when the scrollview handles a fling event. If you overwrite the fling method the won't be any random focus changes.
Then if you want the fling functionality back you'll need to write your own fling method. There's code here you can copy from:

d18279 | test | You can do this:
private final List<Button> mButtons = new ArrayList<>();
// somewhere in your code
mButtons.add(mButton1);
mButtons.add(mButton2);
mButtons.add(mButton3);
mButton1.setOnClickListener(mClickListener);
mButton2.setOnClickListener(mClickListener);
mButton3.setOnClickListener(mClickListener);
private final View.OnClickListener mClickListener = new View.OnClickListener() {
@Override
public void onClick(View v) {
for (Button button : mButtons) {
if (button == v) {
// set selected background
} else {
// set not selected backround
}
}
}
};
If you define a stateful drawable for your buttons, then you can simply change the onclick to this:
private final View.OnClickListener mClickListener = new View.OnClickListener() {
@Override
public void onClick(View v) {
for (Button button : mButtons) {
button.setSelected(v == button);
}
}
};
A: For changing background color/image based on the particular event(focus, press, normal), you need to define a button selector file and implement it as background for button. For example button_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="@drawable/your_image1" /> <!-- pressed -->
<item android:state_focused="true"
android:drawable="@drawable/your_image2" /> <!-- focused -->
android:drawable="@drawable/your_image3" <!-- default -->
</selector>
then just apply it as :
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawable="@drawable/button_selector.xml" />
A: "Pressed", "selected", "disabled" and such are View states. As such they're supposed to be handled automatically by Android and not by your click listeners.
This is achieved using SateLists, which control the look your Views sould have depending on which state(s) they're in. So you can easily set subject_button as the unpressed state, clicked_subject as the pressed state, and let Android take care of actually switching between them.
Full explanation: https://developer.android.com/guide/topics/resources/drawable-resource.html#StateList
A: I solved it by instead of changing only the background color on clicking the button, I also change the textColor, then I can check the textColor with if (((Button) v).getCurrentTextColor() == Color.WHITE) | unknown | |

d18286 | test | I'd actually do something like this (I'm assuming you cant use reversed()). This uses slicing notation to reverse a list.
def reverse(s):
return s[::-1]
I'm also assuming you need to wrap this in a function, you could just use the index notation on its own.
EDIT:
Here is a bit of an explanation of the [::-1] operation:
Slicing notation is of the format [start_point:end_point:step]
The start_point is not specified, this becomes the length of the list so the operation starts at the end.
The end_point is also not specified, this becomes -1 so the operation will end at the start.
The step is -1, so it will iterate backwards in steps of 1 (i.e. every element of the list).
This will create a shallow copy of your original list. This means the list you pass into reverse(s) will remain the same.
Example for clarification:
>>> x = [1, 2, 3]
>>> y = x[::-1]
>>> x
[1, 2, 3]
>>> y
[3, 2, 1]
A: parameter passed to function is of type list.
def reverse(s):
return s[::-1] | unknown | |

d18288 | test | In python there are multiple ways to format strings. using %s inside a string and then a % after the string followed by a tuple (or a single value), allows you to create a new string:
x = 5
y = 8
'my favourite number is %s, but I hate the number %s' % (x, y)
results in:
'my favourite number is 5, but I hate the number 8'

In my opinion, it is easier to format string using f'strings, or .format(). Check out this page too | unknown | |
d18289 | test | You can do it like so.
*
*use groupingBy and create a Map<String, List<String>>
*if the string starts with "el" group using the els key
*otherwise, use the others key
List<String> elements = List.of("e1", "el2", "el3", "4 el", "5 el");
Map<String, List<String>> map = elements.stream().collect(
Collectors.groupingBy(str -> str.startsWith("el") ?
"els" : "others"));
map.entrySet().forEach(System.out::println);
prints
els=[el2, el3]
others=[e1, 4 el, 5 el]
A: Since you have a threshold condition which determine if an item will go to group A, otherwise B, I suggest using partitioningBy for this.
For example:
List<String> elements = List.of("e1", "el2", "el3", "4 el", "5 el");
//create the partition map
Map<Boolean,List<String>> partitionMap = elements.stream()
.collect(Collectors.partitioningBy(s-> s.startsWith("el")));
//getting the partitions
List<String> startsWithEl = partitionMap.get(true);
List<String> notStartingWilEl = partitionMap.get(false);
Now each list will hold its partition . | unknown | |

Public Sub RunCode(Optional ByVal StartLine As Integer = 0)
On Error GoTo Handle
If StartLine > 0 Then
If StartLine = 10 Then GoTo 10
If StartLine = 20 Then GoTo 20
If StartLine = 30 Then GoTo 30
If StartLine = 40 Then GoTo 40

30: Err.Raise -1, "Jones"
40: Debug.Print "40"
Exit Sub
Handle:
Debug.Print "Handle [" & Erl & "]: " & Error
End Sub
The trick used is the Erl statement from VBA... It's generally not used, because it requires the explicit line numbers, seen above... But, since you ALREADY effectively numbered you lines, it would seem like a better option than what you're currently doing.
Second, if you NEED to restart AT or around the line that failed, you need a goto label anyway... That is, you would have to have a third line on each clause the way you're doing it, so you can do a GoTo to it. That is the only way to restart in the middle of your control structure, as you have it. By combining the line numbering as the labels, you effectively reduce this, hopefully making your life easier in the mid-term (not the long term, since numbering your lines is inherently problematic).
The Erl will give you the line that failed, which can be stored somewhere like either a return value or a Global (or wherever you can store and retrieve it). What you have left is the requirement to restart at the given line. Unfortunately, to the best of my knowledge, you can't simply do GoTo StartLine, as would be the easiest, so, as you see, each line is enumerated twice (but, you already had that, right?).. The function, via Optional parameter, can be effectively re-entered at any given point.
This, then, is the most straight-forward way to accomplish your three goals. With that said, you could consider some other options... For example, you could wrap your call to DoCmd.OpenQuery "...", acViewNormal, acEdit in some function, and attempt to apply some retry-logic on the same... That is,
Public Function RetryMyQuery(ByVal Query As String) As Boolean
Const MaxRetries As Long = 5
DoRetry:
On Error Goto QueryFailed
Dim FailureCount as Long
DoCmd.OpenQuery Query, acViewNormal, acEdit
RetryMyQuery = True
Exit Function
QueryFailed:
FailureCount = FailureCount + 1
If FailureCount >= MaxRetries Then Exit Function
If MsgBox("Query Failed [" & Query & "]: " & Err.Description, vbRetryCancel, "Query Failed") = vbRetry Then Resume DoRetry
End Function
Each line in the main function would simply call this function with the query name:
If Not RetryMyQuery("SP_export_sumary") Then MyErrorLine = 19
What this is doing is attempting to retry each operation up to 5 times (configurable), with a message box between each retry to force the user to interact. They can double-check the connection, re-open anything as needed, and try again, or, simply cancel the operation.
The stub function encapsulates the retries and returns True on success, so in the main loop, you can still detect the error, and even record the line that failed, if desired. However, again, if you NEED to re-enter the control logic at any given point, you likely need something like solution #1. Other alternatives to this would be to put the list of operations in some kind of String Array and loop through them, and then you're not re-entering hard-coded logic lines, you just start at an arbitrary point in the list. It depends on your needs.
Hopefully something in this would be of assistance. It is not always possible to change a lot of the control structures on existing code, and while I wouldn't ever set out and design something like the first example, if you merely need to modify what's there, a down-and-dirty way is sometimes the best. Just remember, maintaining line numbers is terrible. BASIC (Before VB or VBA, or even QuickBasic) had line numbers and always had this problem. They aren't used any more for a reason. It should be considered a last resort, but, if it gets things up and going, I've done worse.
NOTE: It may also be helpful to point out that GoTo Labels are only scoped to the current function. Pre-pending the name of the function (Export_to_sp_Err:) only results in more characters being typed, and never being able to remember what the handler is named by the time you get to the end of a long function. Just a tip!
A: The classic way of doing this is to avoid the very limited old scool way of dealing with errors and instead implement a Tryxxx function. The Role of the TryXXX function is to return True of False to indicate the success or fail of an action. One of the parameters (usually the last) is declared as ByRef so that the result of the action can be passed back via the parameter.
I'd also restructure how you provide the strings for the queries so that you separate them from the code that does the querying
XXXQuery is the name of the query for which you have the sequence of query statments.
SOmething along these lines
Public Sub DoXXXQuery(ByRef ipQuerySeq As Collection)

TryDoQuery = False
On Error Resume Next

If Err.Number <> 0 Then
Err.Clear
Exit Function

err.clear
opResult = ????? ' its not clear what the result of the query is

d18297 | test | Using new Integer() will guarantee that you have a new Integer object reference.
Using the value directly will not guarantee that, since auto boxing int to Integer may not do that object instantiation.
I would say that you will only need new Integer(1) in really strange edge cases, so most of the time I would say you never need to do new Integer...
Also please bear in mind that auto boxing / unboxing may produce some errors in some edge cases.
Integer x = null;
int y = x; // Null Pointer Exception
Long iterations where auto(un)boxing is happening may have a performance cost that an untrained eye might not notice
A: Use autoboxing as a default pattern - it's been about forever and makes life ever-so-slightly easier.
Autoboxing is the automatic conversion that the Java compiler makes between the primitive types and their corresponding object wrapper classes. For example, converting an int to an Integer, ..

d18299 | test | If you're curious about this sort of stuff you should play around with Chrome Developer Tools, the Firefox Firebug Addon or the Safari's 'Developer' menu. They're really great at giving you an insight as to what is going on in a webpage
As to "how did they build this" there's many, many different technologies being used up and down the web application stack. Keep in mind the servers storing, caching and fetching all this data are just as much a part of the web application as the frontend. But I imagine your question is asking how "how did they get this webpage to do all this interactive stuff".
Basically it looks like it's all traditional HTML/CSS--no "HTML5" canvas shenanigans or Flash.
The interactivity comes from their custom Javascript code. I tried to figure out if they're using some popular 3rd party Javascript Framework (like jQuery or Prototype) but they are importing so many scripts it's hard to follow. Interestingly enough jQuery and $ are not defined variables on the Evernote page, so it looks like they're not using jQuery at the least. They have clearly written a lot of Javascript to get this thing up and running so it's not that big of a stretch to imagine they they would just decide to keep all their code in-house.
FYI: The three columns are just absolutely positioned and sized <div>s.
<div style="position: absolute; overflow-x: hidden; overflow-y: hidden; left: 0px; top: 0px; bottom: 0px; width: 220px; ">...</div>
<div style="position: absolute; overflow-x: hidden; overflow-y: hidden; left: 220px; top: 0px; bottom: 0px; width: 360px; ">...</div>
<div style="position: absolute; overflow-x: hidden; overflow-y: hidden; left: 580px; top: 0px; right: 0px; bottom: 0px; ">...</div>
The scrolling that you see in those columns is done in child <div>s.
A: webapps like this are usually built with a javascript framework such as backbone, angularjs, ember, etc. here is a reference site which lists them:
http://todomvc.com/
Its hard to see what js framework they are using if any but there are using jQuery 1.8
They are using http://icanhazjs.com/ which is a javascript client side template library.
They are using http://requirejs.org/
A: Well, at the very basic evernote has accomplished its note app workflow using custom javascript, although there are lot of others frameworks they have used for backend work. One way is to see it using Chrome web Inspector nad if on Firefox ,then they have upgraded there web inspector and its much cooler now, but if you prefer the much popular firebug, it will do.
For detailed info, on what are the resources they have used to build, on way is to track it using a web analyzer tool like www.buitwith.com
here, is the link for the homepage of the evernote site , searched over Builtwith.com : http://builtwith.com/?https%3a%2f%2fwww.evernote.com
However the app, that is built upon comprises a lot of custom code. Hard to specify the exact usage, but if we check the code, it doesn't show any of specific use of AngularJS , they do use requireJS for loading modules.
As your question is front-end specific, it can be done using HTML5, with some javascript or if you prefer a framework to ease the process, then checkout this link from JQueryUI.
https://jqueryui.com/resizable/
They are still the kings of UI development, if AngularJS and ReactJS are not mentioned to be overwhelmed.
And also , if you try to do it using plain vanilla JavaScript, that will give you an edge to the learning curve a loads.
A: They use Angular.js, HTML5, CSS3, custom Javascript, and JQuery (and lots of other stuff as others have noted).
