If I have open a package in BIDS ("Business Intelligence Development Studio", the tool you use to design the packages), and do not select any item in it, I have a "Properties" pane in the bottom right containing - among others, the MaximumErrorCount property. If you do not see it, maybe it is minimized and you have to open it (have a look at tabs in the right).

If you cannot find it this way, try the menu: View/Properties Window.

Or try the F4 key.

It's a lose of time to implement from scratch this functionality. I implemented the library recommended by SalutonMondo and I am very satisfied. It is very simple to use and very quick. I improved the original library and I added a new click listener for item click. Also I added font awesome library (http://fortawesome.github.io/Font-Awesome/) and now you can simply add a new item title and specify the icon name from font awesome.

Here is the github link

If you want to create a file and write and append data to it many times, then use the below code, it will create file if not exits and will append data if it exists.

 SimpleDateFormat formatter = new SimpleDateFormat("yyyy_MM_dd");
        Date now = new Date();
        String fileName = formatter.format(now) + ".txt";//like 2016_01_12.txt


         try
            {
                File root = new File(Environment.getExternalStorageDirectory()+File.separator+"Music_Folder", "Report Files");
                //File root = new File(Environment.getExternalStorageDirectory(), "Notes");
                if (!root.exists()) 
                {
                    root.mkdirs();
                }
                File gpxfile = new File(root, fileName);


                FileWriter writer = new FileWriter(gpxfile,true);
                writer.append(sBody+"\n\n");
                writer.flush();
                writer.close();
                Toast.makeText(this, "Data has been written to Report File", Toast.LENGTH_SHORT).show();
            }
            catch(IOException e)
            {
                 e.printStackTrace();

            }

Also iftop:

display bandwidth usage on an interface

iftop does for network usage what top(1) does for CPU usage. It listens to network traffic on a named interface and displays a table of current bandwidth usage by pairs of hosts. Handy for answering the question "why is our ADSL link so slow?"...

Use the System.Environment class.

The methods

var value = System.Environment.GetEnvironmentVariable(variable [, Target])

and

System.Environment.SetEnvironmentVariable(variable, value [, Target])

will do the job for you.

The optional parameter Target is an enum of type EnvironmentVariableTarget and it can be one of: Machine, Process, or User. If you omit it, the default target is the current process.

$.each(JSON.parse(result), function(i, item) {
    alert(item.number);
});

In Word, it is possible to paste code that uses color to differentiate comments from code using "Paste Keep Source Formatting." However, if you use the pasted code to create a new style, Word automatically strips the color coded text and changes them to be black (or whatever the auto default color is). Since applying a style is the best way to ensure compliance with document format requirements, Word is not very useful for documenting software programs. Unfortunately, I don't recall Open Office being any better. The best work-around is to use the default simple text box.

a similar issue is for Visual studio 2015 RC. Sometimes it loses the ability to open RC: you double click but editor do not one menus and dialogs.

Right click on the file *.rc, it will open:

And change as following:

public static void main(String[] args) {
        try {
            File file = new File("test.txt");
            System.out.println(file.length());
        } catch (Exception e) {
        }
    }

Put all the divs in a individual table cells and set the table style to padding: 5px;.

E.g.

<table style="width: 100%; padding: 5px;">_x000D_
<tbody>_x000D_
<tr>_x000D_
<td>_x000D_
<div style="background-color: red;">A</div>_x000D_
</td>_x000D_
<td>_x000D_
<div style="background-color: orange;">B</div>_x000D_
</td>_x000D_
<td>_x000D_
<div style="background-color: green;">C</div>_x000D_
</td>_x000D_
<td>_x000D_
<div style="background-color: blue;">D</div>_x000D_
</td>_x000D_
</tr>_x000D_
</tbody>_x000D_
</table>

Sorry for resurrection. You could use child_process module to execute external js files in node.js

var child_process = require('child_process');

//EXECUTE yourExternalJsFile.js
child_process.exec('node yourExternalJsFile.js', (error, stdout, stderr) => {
    console.log(`${stdout}`);
    console.log(`${stderr}`);
    if (error !== null) {
        console.log(`exec error: ${error}`);
    }
});

You could use streams in Java 8. To always get 10 entries at the most, you could do:

dataList.stream().skip(5).limit(10).collect(Collectors.toList());
dataList.stream().skip(30).limit(10).collect(Collectors.toList());

You can try out this phone validator package. Laravel Phone

Update

I recently discovered another package Lavarel Phone Validator (stuyam/laravel-phone-validator), that uses the free Twilio phone lookup service

When I tried to execute my stored procedure I had the same problem because the size of the column that I need to add some data is shorter than the data I want to add.

You can increase the size of the column data type or reduce the length of your data.

For this you need to run the "tomcat6w" application that is part of the standard Tomcat distribution in the "bin" directory. E.g. for windows the default is "C:\Program Files\Apache Software Foundation\Tomcat 6.0\bin\tomcat6w.exe". The "tomcat6w" application starts a GUI. If you select the "Java" tab you can enter all Java options.

It is also possible to pass JVM options via the command line to tomcat. For this you need to use the command:

<tomcatexecutable> //US//<tomcatservicename> ++JvmOptions="<JVMoptions>"

where "tomcatexecutable" refers to your tomcat application, "tomcatservicename" is the tomcat service name you are using and "JVMoptions" are your JVM options. For instance:

"tomcat6.exe" //US//tomcat6 ++JvmOptions="-XX:MaxPermSize=128m" 

Try loading your javascript after.

Try this:

<h2>Hello World!</h2>
<p id="myParagraph">This is an example website</p>

<form>
  <input type="text" id="myTextfield" placeholder="Type your name" />
  <input type="submit" id="myButton" value="Go" />
</form>

<script src="js/script.js" type="text/javascript"></script>

And if you want to add a row, you can use a dictionary:

df = pd.DataFrame()
df = df.append({'name': 'Zed', 'age': 9, 'height': 2}, ignore_index=True)

which gives you:

   age  height name
0    9       2  Zed

I think, bwawok's answer is wrong at some point:

if you do

git reset --soft c14809fa

It will make your local files changed to be like they were then, but leave your history etc. the same.

According to manual: git-reset, "git reset --soft"...

does not touch the index file nor the working tree at all (but resets the head to <commit>, just like all modes do). This leaves all your changed files "Changes to be committed", as git status would put it.

So it will "remove" newer commits from the branch. This means, after looking at your old code, you cannot go to the newest commit in this branch again, easily. So it does the opposide as described by bwawok: Local files are not changed (they look exactly as before "git reset --soft"), but the history is modified (branch is truncated after the specified commit).

The command for bwawok's answer might be:

git checkout <commit>

You can use this to peek at old revision: How did my code look yesterday?

(I know, I should put this in comments to this answer, but stackoverflow does not allow me to do so! My reputation is too low.)

You can use the jobs -l command to get to a particular jobL

^Z
[1]+  Stopped                 guard

my_mac:workspace r$ jobs -l
[1]+ 46841 Suspended: 18           guard

In this case, 46841 is the PID.

From help jobs:

-l Report the process group ID and working directory of the jobs.

jobs -p is another option which shows just the PIDs.

USING plt.rcParams

There is also this workaround in case you want to change the size without using the figure environment. So in case you are using plt.plot() for example, you can set a tuple with width and height.

import matplotlib.pyplot as plt
plt.rcParams["figure.figsize"] = (20,3)

This is very useful when you plot inline (e.g. with IPython Notebook). As @asamaier noticed is preferable to not put this statement in the same cell of the imports statements.

Conversion to cm

The figsize tuple accepts inches so if you want to set it in centimetres you have to divide them by 2.54 have a look to this question.

Neither.

Django is a framework, not a language. Python is the language in which Django is written.

Django is a collection of Python libs allowing you to quickly and efficiently create a quality Web application, and is suitable for both frontend and backend.

However, Django is pretty famous for its "Django admin", an auto generated backend that allows you to manage your website in a blink for a lot of simple use cases without having to code much.

More precisely, for the front end, Django helps you with data selection, formatting, and display. It features URL management, a templating language, authentication mechanisms, cache hooks, and various navigation tools such as paginators.

For the backend, Django comes with an ORM that lets you manipulate your data source with ease, forms (an HTML independent implementation) to process user input and validate data and signals, and an implementation of the observer pattern. Plus a tons of use-case specific nifty little tools.

For the rest of the backend work Django doesn't help with, you just use regular Python. Business logic is a pretty broad term.

You probably want to know as well that Django comes with the concept of apps, a self contained pluggable Django library that solves a problem. The Django community is huge, and so there are numerous apps that do specific business logic that vanilla Django doesn't.

you can try like this:

var request = require('request');
request.post({ headers: {'content-type' : 'application/json'}
               , url: <your URL>, body: <req_body in json> }
               , function(error, response, body){
   console.log(body); 
}); 

Usually I use this code (into a VBA macro) for getting a cell's value from another cell's value from another sheet:

Range("Y3") = ActiveWorkbook.Worksheets("Reference").Range("X4")

The cell Y3 is into a sheet that I called it "Calculate" The cell X4 is into a sheet that I called it "Reference" The VBA macro has been run when the "Calculate" in active sheet.

I know it is an old question now, but for users who are using Maven plugin with Eclipse under Windows, you have two options:

1. If you got Maven installed as a standalone application:

   You can use the following command in the CMD under your project path:

   mvn eclipse:eclipse
   

   It will update your repository with all the missing jars, according to your dependencies in your pom.xml file.

2. If you haven't got Maven installed as a standalone application you can follow these steps on your eclipse:

   Right click on the project ->Run As -- >Run configurations.

   Then select mavenBuild.

   Then click new button to create a configuration of the selected type .Click on Browse workspace then select your project and in goals specify eclipse:eclipse

You can refer to how to run the command mvn eclipse:eclipse for further details.

Improving Maxime's anwser:

docker ps --size

You'll see something like this:

+---------------+---------------+--------------------+
| CONTAINER ID  | IMAGE         | SIZE               |
+===============+===============+====================+
| 6ca0cef8db8d  | nginx         | 2B (virtual 183MB) |
| 3ab1a4d8dc5a  | nginx         | 5B (virtual 183MB) |
+---------------+---------------+--------------------+

When starting a container, the image that the container is started from is mounted read-only (virtual).
On top of that, a writable layer is mounted, in which any changes made to the container are written.

So the Virtual size (183MB in the example) is used only once, regardless of how many containers are started from the same image - I can start 1 container or a thousand; no extra disk space is used.
The "Size" (2B in the example) is unique per container though, so the total space used on disk is:

183MB + 5B + 2B

Be aware that the size shown does not include all disk space used for a container.
Things that are not included currently are;
- volumes
- swapping
- checkpoints
- disk space used for log-files generated by container

As far as I am aware you have to use javascript to travel up the dom.

Something like this:

$("textarea:focus").parent().attr("border", "thin solid black");

you'll need the jQuery libraries loaded as well.

Portable solution in C#:

long value = 27
long nextPowerOfTwo = 1 << (int)Math.Ceiling(Math.Log2(value));

nextPowerOfTwo is 32.

Math.Ceiling(Math.Log2(value)) calculates the exponent of the next power of two, the 1 << calculates the real value through bitshifting.

To delete the last output only:

? + L

To clear the terminal completely:

? + K

I prefer the PHPMailer tool as it doesn't require PEAR. But either way, you have a misunderstanding: you don't want a PHP-server-wide setting for the SMTP user and password. This should be a per-app (or per-page) setting. If you want to use the same account across different PHP pages, add it to some kind of settings.php file.

JavaScript objects can only use strings as keys (anything else is converted to a string).

You could, alternatively, maintain an array which indexes the objects in question, and use its index string as a reference to the object. Something like this:

var ObjectReference = [];
ObjectReference.push(obj);

set['ObjectReference.' + ObjectReference.indexOf(obj)] = true;

Obviously it's a little verbose, but you could write a couple of methods that handle it and get and set all willy nilly.

Edit:

Your guess is fact -- this is defined behaviour in JavaScript -- specifically a toString conversion occurs meaning that you can can define your own toString function on the object that will be used as the property name. - olliej

This brings up another interesting point; you can define a toString method on the objects you want to hash, and that can form their hash identifier.

You need to set JDK 1.5 to your project and also all dependent project or jar file should also compiled with JDK 1.5

The best solution I've come up with at on the spot (though most likely crude) would be:

String.prototype.getBytes = function() {
    var bytes = [];
    for (var i = 0; i < this.length; i++) {
        var charCode = this.charCodeAt(i);
        var cLen = Math.ceil(Math.log(charCode)/Math.log(256));
        for (var j = 0; j < cLen; j++) {
            bytes.push((charCode << (j*8)) & 0xFF);
        }
    }
    return bytes;
}

Though I notice this question has been here for over a year.

The FOR-LOOP generally works, but there are some issues. The FOR doesn't accept empty lines and lines with more than ~8190 are problematic. The expansion works only reliable, if the delayed expansion is disabled.

Detection of CR/LF versus single LF seems also a little bit complicated.
Also NUL characters are problematic, as a FOR-Loop immediatly cancels the reading.

Direct binary reading seems therefore nearly impossible.

The problem with empty lines can be solved with a trick. Prefix each line with a line number, using the findstr command, and after reading, remove the prefix.

@echo off
SETLOCAL DisableDelayedExpansion
FOR /F "usebackq delims=" %%a in (`"findstr /n ^^ t.txt"`) do (
    set "var=%%a"
    SETLOCAL EnableDelayedExpansion
    set "var=!var:*:=!"
    echo(!var!
    ENDLOCAL
)

Toggling between enable and disabled delayed expansion is neccessary for the safe working with strings, like ! or ^^^xy!z.
That's because the line set "var=%%a" is only safe with DisabledDelayedExpansion, else exclamation marks are removed and the carets are used as (secondary) escape characters and they are removed too.
But using the variable var is only safe with EnabledDelayedExpansion, as even a call %%var%% will fail with content like "&"&.

EDIT: Added set/p variant
There is a second way of reading a file with set /p, the only disadvantages are that it is limited to ~1024 characters per line and it removes control characters at the line end.
But the advantage is, you didn't need the delayed toggling and it's easier to store values in variables

@echo off
setlocal EnableDelayedExpansion
set "file=%~1"

for /f "delims=" %%n in ('find /c /v "" %file%') do set "len=%%n"
set "len=!len:*: =!"

<%file% (
  for /l %%l in (1 1 !len!) do (
    set "line="
    set /p "line="
    echo(!line!
  )
)

For reading it "binary" into a hex-representation
You could look at SO: converting a binary file to HEX representation using batch file

You don't need to set the value at all. ng-model takes care of it all:

• set the input value from the model
• update the model value when you change the input
• update the input value when you change the model from js

Here's the fiddle for this: http://jsfiddle.net/terebentina/9mFpp/

• START_STICKY: It will restart the service in case if it terminated and the Intent data which is passed to the onStartCommand() method is NULL. This is suitable for the service which are not executing commands but running independently and waiting for the job.
• START_NOT_STICKY: It will not restart the service and it is useful for the services which will run periodically. The service will restart only when there are a pending startService() calls. It’s the best option to avoid running a service in case if it is not necessary.
• START_REDELIVER_INTENT: It’s same as STAR_STICKY and it recreates the service, call onStartCommand() with last intent that was delivered to the service.

Another possible reason is that your BIOS CPU visualization is not enabled. Go and enable it first!

Try this:

1. Download and install a 32-bit JDK.
2. Go to eclipse click on your project (Run As ? Run Configurations...) under Java Application branch.
3. Go to the JRE tab and select Alternate JRE. Click on Installed JRE button, add your 32-bit JRE and select.

Here I will hopefully clarify my position.

That NULL = NULL evaluate to FALSE is wrong. Hacker and Mister correctly answered NULL. Here is why. Dewayne Christensen wrote to me, in a comment to Scott Ivey:

Since it's December, let's use a seasonal example. I have two presents under the tree. Now, you tell me if I got two of the same thing or not.

They can be different or they can be equal, you don't know until one open both presents. Who knows? You invited two people that don't know each other and both have done to you the same gift - rare, but not impossible §.

So the question: are these two UNKNOWN presents the same (equal, =)? The correct answer is: UNKNOWN (i.e. NULL).

This example was intended to demonstrate that "..(false or null, depending on your system).." is a correct answer - it is not, only NULL is correct in 3VL (or is ok for you to accept a system which gives wrong answers?)

A correct answer to this question must emphasize this two points:

• three-valued logic (3VL) is counterintuitive (see countless other questions on this subject on Stackoverflow and in other forum to make sure);
• SQL-based DBMSes often do not respect even 3VL, they give wrong answers sometimes (as, the original poster assert, SQL Server do in this case).

So I reiterate: SQL does not any good forcing one to interpret the reflexive property of equality, which state that:

for any x, x = x §§ (in plain English: whatever the universe of discourse, a "thing" is always equal to itself).

.. in a 3VL (TRUE, FALSE, NULL). The expectation of people would conform to 2VL (TRUE, FALSE, which even in SQL is valid for all other values), i.e. x = x always evaluate to TRUE, for any possible value of x - no exceptions.

Note also that NULLs are valid " non-values " (as their apologists pretend them to be) which one can assign as attribute values(??) as part of relation variables. So they are acceptable values of every type (domain), not only of the type of logical expressions.

And this was my point: NULL, as value, is a "strange beast". Without euphemism, I prefer to say: nonsense.

I think that this formulation is much more clear and less debatable - sorry for my poor English proficiency.

This is only one of the problems of NULLs. Better to avoid them entirely, when possible.

§ we are concerned about values here, so the fact that the two presents are always two different physical objects are not a valid objection; if you are not convinced I'm sorry, it is not this the place to explain the difference between value and "object" semantics (Relational Algebra has value semantics from the start - see Codd's information principle; I think that some SQL DBMS implementors don't even care about a common semantics).

§§ to my knowledge, this is an axiom accepted (in a form or another, but always interpreted in a 2VL) since antiquity and that exactly because is so intuitive. 3VLs (is a family of logics in reality) is a much more recent development (but I'm not sure when was first developed).

Side note: if someone will introduce Bottom, Unit and Option Types as attempts to justify SQL NULLs, I will be convinced only after a quite detailed examination that will shows of how SQL implementations with NULLs have a sound type system and will clarify, finally, what NULLs (these "values-not-quite-values") really are.

In what follow I will quote some authors. Any error or omission is probably mine and not of the original authors.

Joe Celko on SQL NULLs

I see Joe Celko often cited on this forum. Apparently he is a much respected author here. So, I said to myself: "what does he wrote about SQL NULLs? How does he explain NULLs numerous problems?". One of my friend has an ebook version of Joe Celko's SQL for smarties: advanced SQL programming, 3rd edition. Let's see.

First, the table of contents. The thing that strikes me most is the number of times that NULL is mentioned and in the most varied contexts:

3.4 Arithmetic and NULLs 109
3.5 Converting Values to and from NULL 110
3.5.1 NULLIF() Function 110
6 NULLs: Missing Data in SQL 185
6.4 Comparing NULLs 190
6.5 NULLs and Logic 190
6.5.1 NULLS in Subquery Predicates 191
6.5.2 Standard SQL Solutions 193
6.6 Math and NULLs 193
6.7 Functions and NULLs 193
6.8 NULLs and Host Languages 194
6.9 Design Advice for NULLs 195
6.9.1 Avoiding NULLs from the Host Programs 197
6.10 A Note on Multiple NULL Values 198
10.1 IS NULL Predicate 241
10.1.1 Sources of NULLs 242
...

and so on. It rings "nasty special case" to me.

I will go into some of these cases with excerpts from this book, trying to limit myself to the essential, for copyright reasons. I think these quotes fall within "fair use" doctrine and they can even stimulate to buy the book - so I hope that no one will complain (otherwise I will need to delete most of it, if not all). Furthermore, I shall refrain from reporting code snippets for the same reason. Sorry about that. Buy the book to read about datailed reasoning.

Page numbers between parenthesis in what follow.

NOT NULL Constraint (11)

The most important column constraint is the NOT NULL, which forbids the use of NULLs in a column. Use this constraint routinely, and remove it only when you have good reason. It will help you avoid the complications of NULL values when you make queries against the data.

It is not a value; it is a marker that holds a place where a value might go.

Again this "value but not quite a value" nonsense. The rest seems quite sensible to me.

(12)

In short, NULLs cause a lot of irregular features in SQL, which we will discuss later. Your best bet is just to memorize the situations and the rules for NULLs when you cannot avoid them.

Apropos of SQL, NULLs and infinite:

(104) CHAPTER 3: NUMERIC DATA IN SQL

SQL has not accepted the IEEE model for mathematics for several reasons.

...

If the IEEE rules for math were allowed in SQL, then we would need type conversion rules for infinite and a way to represent an infinite exact numeric value after the conversion. People have enough trouble with NULLs, so let’s not go there.

SQL implementations undecided on what NULL really means in particular contexts:

3.6.2 Exponential Functions (116)

The problem is that logarithms are undefined when (x <= 0). Some SQL implementations return an error message, some return a NULL and DB2/ 400; version 3 release 1 returned *NEGINF (short for “negative infinity”) as its result.

Joe Celko quoting David McGoveran and C. J. Date:

6 NULLs: Missing Data in SQL (185)

In their book A Guide to Sybase and SQL Server, David McGoveran and C. J. Date said: “It is this writer’s opinion than NULLs, at least as currently defined and implemented in SQL, are far more trouble than they are worth and should be avoided; they display very strange and inconsistent behavior and can be a rich source of error and confusion. (Please note that these comments and criticisms apply to any system that supports SQL-style NULLs, not just to SQL Server specifically.)”

NULLs as a drug addiction:

(186/187)

In the rest of this book, I will be urging you not to use them, which may seem contradictory, but it is not. Think of a NULL as a drug; use it properly and it works for you, but abuse it and it can ruin everything. Your best policy is to avoid NULLs when you can and use them properly when you have to.

My unique objection here is to "use them properly", which interacts badly with specific implementation behaviors.

6.5.1 NULLS in Subquery Predicates (191/192)

People forget that a subquery often hides a comparison with a NULL. Consider these two tables:

...

The result will be empty. This is counterintuitive, but correct.

(separator)

6.5.2 Standard SQL Solutions (193)

SQL-92 solved some of the 3VL (three-valued logic) problems by adding a new predicate of the form:

<search condition> IS [NOT] TRUE | FALSE | UNKNOWN

But UNKNOWN is a source of problems in itself, so that C. J. Date, in his book cited below, reccomends in chapter 4.5. Avoiding Nulls in SQL:

• Don't use the keyword UNKNOWN in any context whatsoever.

Read "ASIDE" on UNKNOWN, also linked below.

6.8 NULLs and Host Languages (194)

However, you should know how NULLs are handled when they have to be passed to a host program. No standard host language for which an embedding is defined supports NULLs, which is another good reason to avoid using them in your database schema.

(separator)

6.9 Design Advice for NULLs (195)

It is a good idea to declare all your base tables with NOT NULL constraints on all columns whenever possible. NULLs confuse people who do not know SQL, and NULLs are expensive.

Objection: NULLs confuses even people that know SQL well, see below.

(195)

NULLs should be avoided in FOREIGN KEYs. SQL allows this “benefit of the doubt” relationship, but it can cause a loss of information in queries that involve joins. For example, given a part number code in Inventory that is referenced as a FOREIGN KEY by an Orders table, you will have problems getting a listing of the parts that have a NULL. This is a mandatory relationship; you cannot order a part that does not exist.

6.9.1 Avoiding NULLs from the Host Programs (197)

You can avoid putting NULLs into the database from the Host Programs with some programming discipline.

...

5. Determine impact of missing data on programming and reporting: Numeric columns with NULLs are a problem, because queries using aggregate functions can provide misleading results.

(227)

The SUM() of an empty set is always NULL. One of the most common programming errors made when using this trick is to write a query that could return more than one row. If you did not think about it, you might have written the last example as: ...

10.1.1 Sources of NULLs (242)

It is important to remember where NULLs can occur. They are more than just a possible value in a column. Aggregate functions on empty sets, OUTER JOINs, arithmetic expressions with NULLs, and OLAP operators all return NULLs. These constructs often show up as columns in VIEWs.

(separator)

(301)

Another problem with NULLs is found when you attempt to convert IN predicates to EXISTS predicates.

(separator)

16.3 The ALL Predicate and Extrema Functions (313)

It is counterintuitive at first that these two predicates are not the same in SQL:

...

But you have to remember the rules for the extrema functions—they drop out all the NULLs before returning the greater or least values. The ALL predicate does not drop NULLs, so you can get them in the results.

(separator)

(315)

However, the definition in the standard is worded in the negative, so that NULLs get the benefit of the doubt. ...

As you can see, it is a good idea to avoid NULLs in UNIQUE constraints.

Discussing GROUP BY:

NULLs are treated as if they were all equal to each other, and form their own group. Each group is then reduced to a single row in a new result table that replaces the old one.

This means that for GROUP BY clause NULL = NULL does not evaluate to NULL, as in 3VL, but it evaluate to TRUE.

SQL standard is confusing:

The ORDER BY and NULLs (329)

Whether a sort key value that is NULL is considered greater or less than a non-NULL value is implementation-defined, but...

... There are SQL products that do it either way.

In March 1999, Chris Farrar brought up a question from one of his developers that caused him to examine a part of the SQL Standard that I thought I understood. Chris found some differences between the general understanding and the actual wording of the specification.

And so on. I think is enough by Celko.

C. J. Date on SQL NULLs

C. J. Date is more radical about NULLs: avoid NULLs in SQL, period. In fact, chapter 4 of his SQL and Relational Theory: How to Write Accurate SQL Code is titled "NO DUPLICATES, NO NULLS", with subchapters "4.4 What's Wrong with Nulls?" and "4.5 Avoiding Nulls in SQL" (follow the link: thanks to Google Books, you can read some pages on-line).

Fabian Pascal on SQL NULLs

From its Practical Issues in Database Management - A Reference for the Thinking Practitioner (no excerpts on-line, sorry):

10.3 Pratical Implications

10.3.1 SQL NULLs

... SQL suffers from the problems inherent in 3VL as well as from many quirks, complications, counterintuitiveness, and outright errors [10, 11]; among them are the following:

• Aggregate functions (e.g., SUM(), AVG()) ignore NULLs (except for COUNT()).
• A scalar expression on a table without rows evaluates incorrectly to NULL, instead of 0.
• The expression "NULL = NULL" evaluates to NULL, but is actually invalid in SQL; yet ORDER BY treats NULLs as equal (whatever they precede or follow "regular" values is left to DBMS vendor).
• The expression "x IS NOT NULL" is not equal to "NOT(x IS NULL)", as is the case in 2VL.

...

All commercially implemented SQL dialects follow this 3VL approach, and, thus, not only do they exibits these problems, but they also have spefic implementation problems, which vary across products.

I have written a generic caching func() which will cache any variable easily and very readable format. Caching function:

function calculateSomethingMaybe(args){
  return args;
}

function caching(fn){
  const cache = {};
  return function(){
    const string = arguments[0];
    if(!cache[string]){
      const result = fn.apply(this, arguments);
      cache[string] = result;
      return result;
    }
    return cache[string];
  }
}

const letsCache = caching(calculateSomethingMaybe);

console.log(letsCache('a book'), letsCache('a pen'), letsCache('a book'));

I suggest using JavaScript's Array method filter() to identify an element by value. It filters data by using a "function to test each element of the array. Return true to keep the element, false otherwise.."

The following function filters the data, returning data for which the callback returns true, i.e. where data.code equals the requested country code.

function getCountryByCode(code) {
  return data.filter(
      function(data){ return data.code == code }
  );
}

var found = getCountryByCode('DZ');

See the demonstration below:

var data = [{_x000D_
  "name": "Afghanistan",_x000D_
  "code": "AF"_x000D_
}, {_x000D_
  "name": "Åland Islands",_x000D_
  "code": "AX"_x000D_
}, {_x000D_
  "name": "Albania",_x000D_
  "code": "AL"_x000D_
}, {_x000D_
  "name": "Algeria",_x000D_
  "code": "DZ"_x000D_
}];_x000D_
_x000D_
_x000D_
function getCountryByCode(code) {_x000D_
  return data.filter(_x000D_
    function(data) {_x000D_
      return data.code == code_x000D_
    }_x000D_
  );_x000D_
}_x000D_
_x000D_
var found = getCountryByCode('DZ');_x000D_
_x000D_
document.getElementById('output').innerHTML = found[0].name;

<div id="output"></div>

Here's a JSFiddle.

I spent a little over an hour trying just about every option presented. I eventually figured out that I had a lot of stale entries for software that I had uninstalled. I deleted all the registry nodes that had any stale data (pointed to the wrong directory). This included the

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Java Runtime Environment]

and

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment]

entries as a JRE included in the JDK.

I also got rid of all the JAVA entries in my environmental variables. I guess I blame it on bad uninstallers that do not clean up after themselves.

If it's reconnecting and getting connection ID 2, the server has almost definitely just crashed.

Contact the server admin and get them to diagnose the problem. No non-malicious SQL should crash the server, and the output of mysqldump certainly should not.

It is probably the case that the server admin has made some big operational error such as assigning buffer sizes of greater than the architecture's address-space limits, or more than virtual memory capacity. The MySQL error-log will probably have some relevant information; they will be monitoring this if they are competent anyway.

You can load the script you need with a promise based solution:

export default {
  data () {
    return { is_script_loading: false }
  },
  created () {
    // If another component is already loading the script
    this.$root.$on('loading_script', e => { this.is_script_loading = true })
  },
  methods: {
    load_script () {
      let self = this
      return new Promise((resolve, reject) => {

        // if script is already loading via another component
        if ( self.is_script_loading ){
          // Resolve when the other component has loaded the script
          this.$root.$on('script_loaded', resolve)
          return
        }

        let script = document.createElement('script')
        script.setAttribute('src', 'https://www.google.com/recaptcha/api.js')
        script.async = true
        
        this.$root.$emit('loading_script')

        script.onload = () => {
          /* emit to global event bus to inform other components
           * we are already loading the script */
          this.$root.$emit('script_loaded')
          resolve()
        }

        document.head.appendChild(script)

      })

    },
  
    async use_script () {
      try {
        await this.load_script()
        // .. do what you want after script has loaded
      } catch (err) { console.log(err) }

    }
  }
}

Please note that this.$root is a little hacky and you should use a vuex or eventHub solution for the global events instead.

You would make the above into a component and use it wherever needed, it will only load the script when used.

NOTE: This is a Vue 2.x based solution. Vue 3 has stopped supporting $on.

It's browser dependent. "By default, Internet Explorer has a KeepAliveTimeout value of one minute and an additional limiting factor (ServerInfoTimeout) of two minutes. Either setting can cause Internet Explorer to reset the socket." - from IE support http://support.microsoft.com/kb/813827

Firefox is around the same value I think as well.

Usually though server timeout are set lower than browser timeouts, but at least you can control that and set it higher.

You'd rather handle the timeout though, so that way you can act upon such an event. See this thread: How to detect timeout on an AJAX (XmlHttpRequest) call in the browser?

While you can use the condition && if-true-part || if-false-part-syntax in older versions of angular, the usual ternary operator condition ? true-part : false-part is available in Angular 1.1.5 and later.

Laravel collections has method last

Model::all() -> last(); // last element 
Model::all() -> last() -> pluck('name'); // extract value from name field. 

This is the best way to do it.

The following JavaScript will open a new browser window, 450px wide by 300px high with scrollbars:

window.open("http://myurl", "_blank", "scrollbars=1,resizable=1,height=300,width=450");

You can add this to a link like so:

<a href='#' onclick='javascript:window.open("http://myurl", "_blank", "scrollbars=1,resizable=1,height=300,width=450");' title='Pop Up'>Pop Up</a>

You Can View All trigger related to your database by below query

select * from sys.triggers

And for open trigger you can use below syntax

A one-line solution using Java 8 features

In Java

LocalDateTime firstOfWeek = LocalDateTime.now().with(ChronoField.DAY_OF_WEEK, 1).toLocalDate().atStartOfDay(); // 2020-06-08 00:00 MONDAY
LocalDateTime firstOfMonth = LocalDateTime.now().with(ChronoField.DAY_OF_MONTH , 1).toLocalDate().atStartOfDay(); // 2020-06-01 00:00
// Convert to milliseconds: 
firstOfWeek.atZone(ZoneId.systemDefault()).toInstant().toEpochMilli();

In Kotlin

val firstOfWeek = LocalDateTime.now().with(ChronoField.DAY_OF_WEEK, 1).toLocalDate().atStartOfDay() // 2020-06-08 00:00 MONDAY
val firstOfMonth = LocalDateTime.now().with(ChronoField.DAY_OF_MONTH , 1).toLocalDate().atStartOfDay() // 2020-06-01 00:00
// Convert to milliseconds: 
firstOfWeek.atZone(ZoneId.systemDefault()).toInstant().toEpochMilli()

TL;DR

You want this:

AAPL:
  - shares: -75.088
    date: 11/27/2015
  - shares: 75.088
    date: 11/26/2015

Mappings

The YAML equivalent of a JSON object is a mapping, which looks like these:

# flow style
{ foo: 1, bar: 2 }

# block style
foo: 1
bar: 2

Note that the first characters of the keys in a block mapping must be in the same column. To demonstrate:

# OK
   foo: 1
   bar: 2

# Parse error
   foo: 1
    bar: 2

Sequences

The equivalent of a JSON array in YAML is a sequence, which looks like either of these (which are equivalent):

# flow style
[ foo bar, baz ]

# block style
- foo bar
- baz

In a block sequence the -s must be in the same column.

JSON to YAML

Let's turn your JSON into YAML. Here's your JSON:

{"AAPL": [
  {
    "shares": -75.088,
    "date": "11/27/2015"
  },
  {
    "shares": 75.088,
    "date": "11/26/2015"
  },
]}

As a point of trivia, YAML is a superset of JSON, so the above is already valid YAML—but let's actually use YAML's features to make this prettier.

Starting from the inside out, we have objects that look like this:

{
  "shares": -75.088,
  "date": "11/27/2015"
}

The equivalent YAML mapping is:

shares: -75.088
date: 11/27/2015

We have two of these in an array (sequence):

- shares: -75.088
  date: 11/27/2015
- shares: 75.088
  date: 11/26/2015

Note how the -s line up and the first characters of the mapping keys line up.

Finally, this sequence is itself a value in a mapping with the key AAPL:

AAPL:
  - shares: -75.088
    date: 11/27/2015
  - shares: 75.088
    date: 11/26/2015

Parsing this and converting it back to JSON yields the expected result:

{
  "AAPL": [
    {
      "date": "11/27/2015", 
      "shares": -75.088
    }, 
    {
      "date": "11/26/2015", 
      "shares": 75.088
    }
  ]
}

You need the sleep method of the Thread class.

public static void sleep (long time)

Causes the thread which sent this message to sleep for the given interval of time (given in milliseconds). The precision is not guaranteed - the Thread may sleep more or less than requested.

Parameters

time The time to sleep in milliseconds.

Your solution requires some ajax method to pass the html to a back-end server that has a html to pdf facility and then returning the pdf output generated back to the browser.

First setting up the client side code, we will setup the jquery code as

   var options = {
            "url": "/pdf/generate/convert_to_pdf.php",
            "data": "data=" + $("#content").html(),
            "type": "post",
        }
   $.ajax(options)

Then intercept the data from the html2pdf generation script (somewhere from the internet).
convert_to_pdf.php (given as url in JQUERY code) looks like this -

<?php
    $html = $_POST['data'];
    $pdf = html2pdf($html);
    
    header("Content-Type: application/pdf"); //check this is the proper header for pdf
    header("Content-Disposition: attachment; filename='some.pdf';");
    echo $pdf;
?>

Remove the course_enrollment_settings.base_price immediately after CASE:

SELECT
   CASE
    WHEN course_enrollment_settings.base_price = 0      THEN 1
    ...
    END

CASE has two different forms, as detailed in the manual. Here, you want the second form since you're using search conditions.

This is an image registration problem. The general strategy is:

• Have a known example, or some kind of prior on the data.
• Fit your data to the example, or fit the example to your data.
• It helps if your data is roughly aligned in the first place.

Here's a rough and ready approach, "the dumbest thing that could possibly work":

• Start with five toe coordinates in roughly the place you expect.
• With each one, iteratively climb to the top of the hill. i.e. given current position, move to maximum neighbouring pixel, if its value is greater than current pixel. Stop when your toe coordinates have stopped moving.

To counteract the orientation problem, you could have 8 or so initial settings for the basic directions (North, North East, etc). Run each one individually and throw away any results where two or more toes end up at the same pixel. I'll think about this some more, but this kind of thing is still being researched in image processing - there are no right answers!

Slightly more complex idea: (weighted) K-means clustering. It's not that bad.

• Start with five toe coordinates, but now these are "cluster centres".

Then iterate until convergence:

• Assign each pixel to the closest cluster (just make a list for each cluster).
• Calculate the center of mass of each cluster. For each cluster, this is: Sum(coordinate * intensity value)/Sum(coordinate)
• Move each cluster to the new centre of mass.

This method will almost certainly give much better results, and you get the mass of each cluster which may help in identifying the toes.

(Again, you've specified the number of clusters up front. With clustering you have to specify the density one way or another: Either choose the number of clusters, appropriate in this case, or choose a cluster radius and see how many you end up with. An example of the latter is mean-shift.)

Sorry about the lack of implementation details or other specifics. I would code this up but I've got a deadline. If nothing else has worked by next week let me know and I'll give it a shot.

Ignoring checking is a bad idea as it makes you susceptible to Man-in-the-middle attacks.

I took the freedom to improve nikobelia's answer by only adding each machine's key once and actually setting ok/changed status in Ansible:

- name: Accept EC2 SSH host keys
  connection: local
  become: false
  shell: |
    ssh-keygen -F {{ inventory_hostname }} || 
      ssh-keyscan -H {{ inventory_hostname }} >> ~/.ssh/known_hosts
  register: known_hosts_script
  changed_when: "'found' not in known_hosts_script.stdout"

However, Ansible starts gathering facts before the script runs, which requires an SSH connection, so we have to either disable this task or manually move it to later:

- name: Example play
  hosts: all
  gather_facts: no  # gather facts AFTER the host key has been accepted instead

  tasks:

  # https://stackoverflow.com/questions/32297456/
  - name: Accept EC2 SSH host keys
    connection: local
    become: false
    shell: |
      ssh-keygen -F {{ inventory_hostname }} ||

One kink I haven't been able to work out is that it marks all as changed even if it only adds a single key. If anyone could contribute a fix that would be great!

Note: These solutions work for various versions of Java including Java 8, Java 11, and the new Java 15, and for any other previous Java version covered by the listed version managers. This includes alternative JDK's from OpenJDK, Oracle, IBM, Azul, Amazon Correto, Graal and more. Easily work with Java 7, Java 8, Java 9, Java 10, Java 11, Java 12, Java 13, Java 14, and Java 15!

You have a few options for how to do the installation as well as manage JDK switching. Installation can be done by Homebrew, SDKMAN, Jabba, or a manual install. Switching can be done by JEnv, SDKMAN, Jabba, or manually by setting JAVA_HOME. All of these are described below.

Installation

First, install Java using whatever method you prefer including Homebrew, SDKMAN or a manual install of the tar.gz file. The advantage of a manual install is that the location of the JDK can be placed in a standardized location for Mac OSX. Otherwise, there are easier options such as SDKMAN that also will install other important and common tools for the JVM.

Installing and Switching versions with SDKMAN

SDKMAN is a bit different and handles both the install and the switching. SDKMAN also places the installed JDK's into its own directory tree, which is typically ~/.sdkman/candidates/java. SDKMAN allows setting a global default version, and a version specific to the current shell.

1. Install SDKMAN from https://sdkman.io/install

2. List the Java versions available to make sure you know the version ID

   sdk list java
   

3. Install one of those versions, for example, Java 15:

   sdk install java 15-open 
   

4. Make 15 the default version:

   sdk default java 15-open
   

   Or switch to 15 for the session:

   sdk use java 15-open
   

When you list available versions for installation using the list command, you will see a wide variety of distributions of Java:

sdk list java

And install additional versions, such as JDK 8:

sdk install java 8.0.181-oracle

SDKMAN can work with previously installed existing versions. Just do a local install giving your own version label and the location of the JDK:

sdk install java my-local-13 /Library/Java/JavaVirtualMachines/jdk-13.jdk/Contents/Home

And use it freely:

sdk use java my-local-13

More information is available in the SDKMAN Usage Guide along with other SDK's it can install and manage.

SDKMAN will automatically manage your PATH and JAVA_HOME for you as you change versions.

Install manually from OpenJDK download page:

1. Download OpenJDK for Mac OSX from http://jdk.java.net/ (for example Java 15)

2. Unarchive the OpenJDK tar, and place the resulting folder (i.e. jdk-15.jdk) into your /Library/Java/JavaVirtualMachines/ folder since this is the standard and expected location of JDK installs. You can also install anywhere you want in reality.

Install with Homebrew

The version of Java available in Homebrew Cask previous to October 3, 2018 was indeed the Oracle JVM. Now, however, it has now been updated to OpenJDK. Be sure to update Homebrew and then you will see the lastest version available for install.

1. install Homebrew if you haven't already. Make sure it is updated:

    brew update
   

2. Add the casks tap, if you want to use the AdoptOpenJDK versions (which tend to be more current):

    brew tap adoptopenjdk/openjdk
   

   These casks change their Java versions often, and there might be other taps out there with additional Java versions.

3. Look for installable versions:

    brew search java   
   

   or for AdoptOpenJDK versions:

    brew search jdk     
   

4. Check the details on the version that will be installed:

    brew info java
   

   or for the AdoptOpenJDK version:

    brew info adoptopenjdk
   

5. Install a specific version of the JDK such as java11, adoptopenjdk8, or adoptopenjdk13, or just java or adoptopenjdk for the most current of that distribution. For example:

    brew install java
   
    brew cask install adoptopenjdk13
   

And these will be installed into /Library/Java/JavaVirtualMachines/ which is the traditional location expected on Mac OSX.

Other installation options:

Some other flavours of OpenJDK are:

Azul Systems Java Zulu certified builds of OpenJDK can be installed by following the instructions on their site.

Zulu® is a certified build of OpenJDK that is fully compliant with the Java SE standard. Zulu is 100% open source and freely downloadable. Now Java developers, system administrators, and end-users can enjoy the full benefits of open source Java with deployment flexibility and control over upgrade timing.

Amazon Correto OpenJDK builds have an easy to use an installation package for Java 8 or Java 11, and installs to the standard /Library/Java/JavaVirtualMachines/ directory on Mac OSX.

Amazon Corretto is a no-cost, multiplatform, production-ready distribution of the Open Java Development Kit (OpenJDK). Corretto comes with long-term support that will include performance enhancements and security fixes. Amazon runs Corretto internally on thousands of production services and Corretto is certified as compatible with the Java SE standard. With Corretto, you can develop and run Java applications on popular operating systems, including Linux, Windows, and macOS.

Where is my JDK?!?!

To find locations of previously installed Java JDK's installed at the default system locations, use:

/usr/libexec/java_home -V

Matching Java Virtual Machines (8):
15, x86_64: "OpenJDK 15" /Library/Java/JavaVirtualMachines/jdk-15.jdk/Contents/Home 14, x86_64: "OpenJDK 14" /Library/Java/JavaVirtualMachines/jdk-14.jdk/Contents/Home 13, x86_64: "OpenJDK 13" /Library/Java/JavaVirtualMachines/openjdk-13.jdk/Contents/Home 12, x86_64: "OpenJDK 12" /Library/Java/JavaVirtualMachines/jdk-12.jdk/Contents/Home
11, x86_64: "Java SE 11" /Library/Java/JavaVirtualMachines/jdk-11.jdk/Contents/Home
10.0.2, x86_64: "Java SE 10.0.2" /Library/Java/JavaVirtualMachines/jdk-10.0.2.jdk/Contents/Home
9, x86_64: "Java SE 9" /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home
1.8.0_144, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home

You can also report just the location of a specific Java version using -v. For example for Java 15:

/usr/libexec/java_home -v 15

/Library/Java/JavaVirtualMachines/jdk-15.jdk/Contents/Home

Knowing the location of the installed JDK's is also useful when using tools like JEnv, or adding a local install to SDKMAN, or linking a system JDK in Jabba -- and you need to know where to find them.

If you need to find JDK's installed by other tools, check these locations:

• SDKMAN installs to ~/.sdkman/candidates/java/
• Jabba installs to ~/.jabba/jdk

Switching versions manually

The Java executable is a wrapper that will use whatever JDK is configured in JAVA_HOME, so you can change that to also change which JDK is in use.

For example, if you installed or untar'd JDK 15 to /Library/Java/JavaVirtualMachines/jdk-15.jdk if it is the highest version number it should already be the default, if not you could simply set:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-15.jdk/Contents/Home

And now whatever Java executable is in the path will see this and use the correct JDK.

Using the /usr/libexec/java_home utility as previously described helps you to create aliases or to run commands to change Java versions by identifying the locations of different JDK installations. For example, creating shell aliases in your .profile or .bash_profile to change JAVA_HOME for you:

export JAVA_8_HOME=$(/usr/libexec/java_home -v1.8)
export JAVA_9_HOME=$(/usr/libexec/java_home -v9)
export JAVA_10_HOME=$(/usr/libexec/java_home -v10)
export JAVA_11_HOME=$(/usr/libexec/java_home -v11)
export JAVA_12_HOME=$(/usr/libexec/java_home -v12)
export JAVA_13_HOME=$(/usr/libexec/java_home -v13)
export JAVA_14_HOME=$(/usr/libexec/java_home -v14)
export JAVA_15_HOME=$(/usr/libexec/java_home -v15)

alias java8='export JAVA_HOME=$JAVA_8_HOME'
alias java9='export JAVA_HOME=$JAVA_9_HOME'
alias java10='export JAVA_HOME=$JAVA_10_HOME'
alias java11='export JAVA_HOME=$JAVA_11_HOME'
alias java12='export JAVA_HOME=$JAVA_12_HOME'
alias java13='export JAVA_HOME=$JAVA_13_HOME'
alias java14='export JAVA_HOME=$JAVA_14_HOME'
alias java15='export JAVA_HOME=$JAVA_15_HOME'

# default to Java 15
java15

Then to change versions, just use the alias.

java8
java -version

java version "1.8.0_144"

Of course, setting JAVA_HOME manually works too!

Switching versions with JEnv

JEnv expects the Java JDK's to already exist on the machine and can be in any location. Typically you will find installed Java JDK's in /Library/Java/JavaVirtualMachines/. JEnv allows setting the global version of Java, one for the current shell, and a per-directory local version which is handy when some projects require different versions than others.

1. Install JEnv if you haven't already, instructions on the site http://www.jenv.be/ for manual install or using Homebrew.

2. Add any Java version to JEnv (adjust the directory if you placed this elsewhere):

   jenv add /Library/Java/JavaVirtualMachines/jdk-15.jdk/Contents/Home
   

3. Set your global version using this command:

   jenv global 15
   

You can also add other existing versions using jenv add in a similar manner, and list those that are available. For example Java 8:

jenv add /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home 
jenv versions

See the JEnv docs for more commands. You may now switch between any Java versions (Oracle, OpenJDK, other) at any time either for the whole system, for shells, or per local directory.

To help manage JAVA_HOME while using JEnv you can add the export plugin to do this for you.

$ jenv enable-plugin export
  You may restart your session to activate jenv export plugin echo export plugin activated

The export plugin may not adjust JAVA_HOME if it is already set, so you may need to clear this variable in your profile so that it can be managed by JEnv.

You can also use jenv exec <command> <parms...> to run single commands with JAVA_HOME and PATH set correctly for that one command, which could include opening another shell.

Installing and Switching versions with Jabba

Jabba also handles both the install and the switching. Jabba also places the installed JDK's into its own directory tree, which is typically ~/.jabba/jdk.

1. Install Jabba by following the instructions on the home page.

2. List available JDK's

   jabba ls-remote

3. Install Java JDK 12

   jabba install [email protected]

4. Use it:

   jabba use [email protected]

You can also alias version names, link to existing JDK's already installed, and find a mix of interesting JDK's such as GraalVM, Adopt JDK, IBM JDK, and more. The complete usage guide is available on the home page as well.

Jabba will automatically manage your PATH and JAVA_HOME for you as you change versions.

import { DOCUMENT } from '@angular/common';

Spring security logging for webflux reactive apps is now available starting with version 5.4.0-M2 (as mentionned by @bzhu in comment How do I enable logging for Spring Security?)

}

I am assuming you are using msys git. If you are, the editor that is popping up to write your commit message is vim. Vim is not friendly at first. You may prefer to switch to a different editor. If you want to use a different editor, look at this answer: How do I use Notepad++ (or other) with msysgit?

If you want to use vim, type i to type in your message. When happy hit ESC. Then type :wq, and git will then be happy.

Or just type git commit -m "your message here" to skip the editor altogether.

Looking at:

No public installers with the RunInstallerAttribute.Yes attribute could be found in the C:\Users\myusername\Documents\Visual Studio 2010\Projects\TestService\TestSe rvice\obj\x86\Debug\TestService.exe assembly.

It looks like you may not have an installer class in your code. This is a class that inherits from Installer that will tell installutil how to install your executable as a service.

P.s. I have my own little self-installing/debuggable Windows Service template here which you can copy code from or use: Debuggable, Self-Installing Windows Service

This is the best post I've seen on splash screens: http://saulmm.github.io/avoding-android-cold-starts

Saúl Molinero goes into two different options for splash screens: Taking advantage of the window background to animate into your initial screen and displaying placeholder UI (which is a popular choice that Google uses for most of their apps these days).

I refer to this post every time I need to consider cold start time and avoiding user dropoff due to long startup times.

Hope this helps!

Javac – compiler that converts source code to byte code. JVM- interpreter that converts byte code to machine language code.

As we know java is both compile**r & **interpreter based language. Once the java code also known as source code is compiled, it gets converted to native code known as BYTE CODE which is portable & can be easily executed on all operating systems. Byte code generated is basically represented in hexa decimal format. This format is same on every platform be it Solaris work station or Macintosh, windows or Linux. After compilation, the interpreter reads the generated byte code & translates it according to the host machine. . Byte code is interpreted by Java Virtual Machine which is available with all the operating systems we install. so to port Java programs to a new platform all that is required is to port the interpreter and some of the library routines.

Hope it helps!!!

"validate Email"-Solution for Swift 4: Create this class:

import Foundation

public class EmailAddressValidator {
    public init() {
    }

    public func validateEmailAddress(_ email: String) -> Bool {
        let emailTest = NSPredicate(format: "SELF MATCHES %@", String.emailValidationRegEx)

        return emailTest.evaluate(with: email)
    }
}

private extension String {
    static let emailValidationRegEx = "(?:[\\p{L}0-9!#$%\\&'*+/=?\\^_`{|}~-]+(?:\\.[\\p{L}0-9!#$%\\&'*+/=?\\^_`{|}" +
        "~-]+)*|\"(?:[\\x01-\\x08\\x0b\\x0c\\x0e-\\x1f\\x21\\x23-\\x5b\\x5d-\\" +
        "x7f]|\\\\[\\x01-\\x09\\x0b\\x0c\\x0e-\\x7f])*\")@(?:(?:[\\p{L}0-9](?:[a-" +
        "z0-9-]*[\\p{L}0-9])?\\.)+[\\p{L}0-9](?:[\\p{L}0-9-]*[\\p{L}0-9])?|\\[(?:(?:25[0-5" +
        "]|2[0-4][0-9]|[01]?[0-9][0-9]?)\\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-" +
        "9][0-9]?|[\\p{L}0-9-]*[\\p{L}0-9]:(?:[\\x01-\\x08\\x0b\\x0c\\x0e-\\x1f\\x21" +
    "-\\x5a\\x53-\\x7f]|\\\\[\\x01-\\x09\\x0b\\x0c\\x0e-\\x7f])+)\\])"
}

and use it like this:

let validator = EmailAddressValidator()
let isValid = validator.validateEmailAddress("[email protected]")

Considering the previous answers, it is necessary to be careful with globalized characters.

Suppose the name of the file is: "Esdrújula prenda ñame - güena.jpg"

Raw result to download: "Esdrújula prenda ñame - güena.jpg" [Ugly]

HtmlEncode result to download: "Esdr&_250;jula prenda &_241;ame - g&_252;ena.jpg" [Ugly]

UrlEncode result to download: "Esdrújula+prenda+ñame+-+güena.jpg" [OK]

Then, you need almost always to use the UrlEncode over the file name. Moreover, if you set the content-disposition header as direct string, then you need to ensure surround with quotes to avoid browser compatibility issues.

Response.AddHeader("Content-Disposition", $"attachment; filename=\"{HttpUtility.UrlEncode(YourFilename)}\"");

or with class aid:

var cd = new ContentDisposition("attachment") { FileName = HttpUtility.UrlEncode(resultFileName) };
Response.AddHeader("Content-Disposition", cd.ToString());

The System.Net.Mime.ContentDisposition class takes care of quotes.

I know the question is aimed at the direct escaping of the apostrophe character but I assume that usually this is going to be triggered by some sort of program providing the input.

What I have done universally in the scripts and programs I have worked with is to substitute it with a ` character when processing the formatting of the text being input.

Now I know that in some cases, the backtick character may in fact be part of what you might be trying to save (such as on a forum like this) but if you're simply saving text input from users it's a possible solution.

Going into the SQL database

$newval=~s/\'/`/g;

Then, when coming back out for display, filtered again like this:

$showval=~s/`/\'/g;

This example was when PERL/CGI is being used but it can apply to PHP and other bases as well. I have found it works well because I think it helps prevent possible injection attempts, because all ' are removed prior to attempting an insertion of a record.

HTTP Basic Access Authentication

• STEP 1 : the client makes a request for information, sending a username and password to the server in plain text
• STEP 2 : the server responds with the desired information or an error

Basic Authentication uses base64 encoding(not encryption) for generating our cryptographic string which contains the information of username and password. HTTP Basic doesn’t need to be implemented over SSL, but if you don’t, it isn’t secure at all. So I’m not even going to entertain the idea of using it without.

Pros:

• Its simple to implement, so your client developers will have less work to do and take less time to deliver, so developers could be more likely to want to use your API
• Unlike Digest, you can store the passwords on the server in whatever encryption method you like, such as bcrypt, making the passwords more secure
• Just one call to the server is needed to get the information, making the client slightly faster than more complex authentication methods might be

Cons:

• SSL is slower to run than basic HTTP so this causes the clients to be slightly slower
• If you don’t have control of the clients, and can’t force the server to use SSL, a developer might not use SSL, causing a security risk

In Summary – if you have control of the clients, or can ensure they use SSL, HTTP Basic is a good choice. The slowness of the SSL can be cancelled out by the speed of only making one request

Syntax of basic Authentication

Value = username:password
Encoded Value =  base64(Value)
Authorization Value = Basic <Encoded Value> 
//at last Authorization key/value map added to http header as follows
Authorization: <Authorization Value>

HTTP Digest Access Authentication
Digest Access Authentication uses the hashing(i.e digest means cut into small pieces) methodologies to generate the cryptographic result. HTTP Digest access authentication is a more complex form of authentication that works as follows:

• STEP 1 : a client sends a request to a server
• STEP 2 : the server responds with a special code (called a nonce i.e. number used only once), another string representing the realm(a hash) and asks the client to authenticate
• STEP 3 : the client responds with this nonce and an encrypted version of the username, password and realm (a hash)
• STEP 4 : the server responds with the requested information if the client hash matches their own hash of the username, password and realm, or an error if not

Pros:

• No usernames or passwords are sent to the server in plaintext, making a non-SSL connection more secure than an HTTP Basic request that isn’t sent over SSL. This means SSL isn’t required, which makes each call slightly faster

Cons:

• For every call needed, the client must make 2, making the process slightly slower than HTTP Basic
• HTTP Digest is vulnerable to a man-in-the-middle security attack which basically means it could be hacked
• HTTP Digest prevents use of the strong password encryption, meaning the passwords stored on the server could be hacked

In Summary, HTTP Digest is inherently vulnerable to at least two attacks, whereas a server using strong encryption for passwords with HTTP Basic over SSL is less likely to share these vulnerabilities.

If you don’t have control over your clients however they could attempt to perform Basic authentication without SSL, which is much less secure than Digest.

RFC 2069 Digest Access Authentication Syntax

Hash1=MD5(username:realm:password)
Hash2=MD5(method:digestURI)
response=MD5(Hash1:nonce:Hash2)

RFC 2617 Digest Access Authentication Syntax

Hash1=MD5(username:realm:password)
Hash2=MD5(method:digestURI)
response=MD5(Hash1:nonce:nonceCount:cnonce:qop:Hash2)
//some additional parameters added 

source and example

In Postman looks as follows:

Note:

• The Basic and Digest schemes are dedicated to the authentication using a username and a secret.
• The Bearer scheme is dedicated to the authentication using a token.

From the man page:

-d delim The first character of delim is used to terminate the input line, rather than newline.

You are using -d, which will terminate the input line on the comma. It will not read the rest of the line. That's why $y is empty.

For an incoming request like /v1/location/1234, as you can imagine it would be difficult for Web API to automatically figure out if the value of the segment corresponding to '1234' is related to appid and not to deviceid.

I think you should change your route template to be like [Route("v1/location/{deviceOrAppid?}", Name = "AddNewLocation")] and then parse the deiveOrAppid to figure out the type of id.

Also you need to make the segments in the route template itself optional otherwise the segments are considered as required. Note the ? character in this case. For example: [Route("v1/location/{deviceOrAppid?}", Name = "AddNewLocation")]

Create a footer view layout consisting of text that you want to set as footer and then try

View footerView = ((LayoutInflater) ActivityContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_layout, null, false);
ListView.addFooterView(footerView);

Layout for footer could be something like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingTop="7dip"
    android:paddingBottom="7dip"
    android:orientation="horizontal"
    android:gravity="center">

    <LinearLayout 
        android:id="@+id/footer_layout" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:gravity="center"
        android:layout_gravity="center">

    <TextView 
        android:text="@string/footer_text_1" 
        android:id="@+id/footer_1" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:textSize="14dip" 
        android:textStyle="bold" 
        android:layout_marginRight="5dip" />
    </LinearLayout>
</LinearLayout> 

The activity class could be:

public class MyListActivty extends ListActivity {
    private Context context = null;
    private ListView list = null;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        list = (ListView)findViewById(android.R.id.list);

        //code to set adapter to populate list
        View footerView =  ((LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_layout, null, false);
        list.addFooterView(footerView);
    }
}

You need to edit the Tomcat/conf/server.xml and change the connector port. The connector setting should look something like this:

<Connector port="8080" maxHttpHeaderSize="8192"
           maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           connectionTimeout="20000" disableUploadTimeout="true" />

Just change the connector port from default 8080 to another valid port number.

Use

white-space: pre-line;

It will prevent text from flowing out of the div. It will break the text as it reaches the end of the div.

A TextBlock does not actually inherit from Control so it does not have properties that you would generally associate with a Control. Your best bet for adding a border in a style is to replace the TextBlock with a Label

See this link for more on the differences between a TextBlock and other Controls

I don't know if this solves your problem but instead of:

$("#tbIntervalos").find("td").attr("id", horaInicial);

you can just do:

$("#tbIntervalos td#" + horaInicial);

SELECT * FROM sys.objects WHERE type='p' ORDER BY modify_date DESC

SELECT name, create_date, modify_date 
FROM sys.objects
WHERE type = 'P'

SELECT name, crdate, refdate

WHERE type = 'P' 
ORDER BY refdate desc

A very easy way to invoke return and non return value subroutines. is using Func and Action respectively. (see also https://msdn.microsoft.com/en-us/library/018hxwa8(v=vs.110).aspx)

Try this this example

using System;

public class Program
{
    private Func<string,string> FunctionPTR = null;  
    private Func<string,string, string> FunctionPTR1 = null;  
    private Action<object> ProcedurePTR = null; 



    private string Display(string message)  
    {  
        Console.WriteLine(message);  
        return null;  
    }  

    private string Display(string message1,string message2)  
    {  
        Console.WriteLine(message1);  
        Console.WriteLine(message2);  
        return null;  
    }  

    public void ObjectProcess(object param)
    {
        if (param == null)
        {
            throw new ArgumentNullException("Parameter is null or missing");
        }
        else 
        {
            Console.WriteLine("Object is valid");
        }
    }


    public void Main(string[] args)  
    {  
        FunctionPTR = Display;  
        FunctionPTR1= Display;  
        ProcedurePTR = ObjectProcess;
        FunctionPTR("Welcome to function pointer sample.");  
        FunctionPTR1("Welcome","This is function pointer sample");   
        ProcedurePTR(new object());
    }  
}

If I want tranfer only the response variable y instead of a linear model with x specified, eg I wanna transfer/normalize a list of data, I can take 1 for x, then the object becomes a linear model:

library(MASS)
y = rf(500,30,30)
hist(y,breaks = 12)
result = boxcox(y~1, lambda = seq(-5,5,0.5))
mylambda = result$x[which.max(result$y)]
mylambda
y2 = (y^mylambda-1)/mylambda
hist(y2)

<?php
  for ($n = 0; $n <= 7; $n++) {
    echo '<p>'.($n + 1).'</p>';
    echo '<p>'.($n * 2 + 1).'</p>';
  }
?>

You can add line-height:51px to #AlertDiv h1 if you know it's only ever going to be one line. Also add text-align:center to #AlertDiv.

#AlertDiv {
    top:198px;
    left:365px;
    width:62px;
    height:51px;
    color:white;
    position:absolute;
    text-align:center;
    background-color:black;
}

#AlertDiv h1 {
    margin:auto;
    line-height:51px;
    vertical-align:middle;
}

The demo below also uses negative margins to keep the #AlertDiv centered on both axis, even when the window is resized.

I realize that this question is over 10 years old, but it appears to me that not only has the most obvious answer not been addressed, but that maybe its not really clear from the question a good understanding of what goes on under the covers. In addition, there are other questions about late binding and what that means with regards to delegates and lambdas (more on that later).

First to address the 800 lb elephant/gorilla in the room, when to choose event vs Action<T>/Func<T>:

• Use a lambda to execute one statement or method. Use event when you want more of a pub/sub model with multiple statements/lambdas/functions that will execute (this is a major difference right off the bat).
• Use a lambda when you want to compile statements/functions to expression trees. Use delegates/events when you want to participate in more traditional late binding such as used in reflection and COM interop.

As an example of an event, lets wire up a simple and 'standard' set of events using a small console application as follows:

public delegate void FireEvent(int num);

public delegate void FireNiceEvent(object sender, SomeStandardArgs args);

public class SomeStandardArgs : EventArgs
{
    public SomeStandardArgs(string id)
    {
        ID = id;
    }

    public string ID { get; set; }
}

class Program
{
    public static event FireEvent OnFireEvent;

    public static event FireNiceEvent OnFireNiceEvent;


    static void Main(string[] args)
    {
        OnFireEvent += SomeSimpleEvent1;
        OnFireEvent += SomeSimpleEvent2;

        OnFireNiceEvent += SomeStandardEvent1;
        OnFireNiceEvent += SomeStandardEvent2;


        Console.WriteLine("Firing events.....");
        OnFireEvent?.Invoke(3);
        OnFireNiceEvent?.Invoke(null, new SomeStandardArgs("Fred"));

        //Console.WriteLine($"{HeightSensorTypes.Keyence_IL030}:{(int)HeightSensorTypes.Keyence_IL030}");
        Console.ReadLine();
    }

    private static void SomeSimpleEvent1(int num)
    {
        Console.WriteLine($"{nameof(SomeSimpleEvent1)}:{num}");
    }
    private static void SomeSimpleEvent2(int num)
    {
        Console.WriteLine($"{nameof(SomeSimpleEvent2)}:{num}");
    }

    private static void SomeStandardEvent1(object sender, SomeStandardArgs args)
    {

        Console.WriteLine($"{nameof(SomeStandardEvent1)}:{args.ID}");
    }
    private static void SomeStandardEvent2(object sender, SomeStandardArgs args)
    {
        Console.WriteLine($"{nameof(SomeStandardEvent2)}:{args.ID}");
    }
}

The output will look as follows:

If you did the same with Action<int> or Action<object, SomeStandardArgs>, you would only see SomeSimpleEvent2 and SomeStandardEvent2.

So whats going on inside of event?

If we expand out FireNiceEvent, the compiler is actually generating the following (I have omitted some details with respect to thread synchronization that isn't relevant to this discussion):

   private EventHandler<SomeStandardArgs> _OnFireNiceEvent;

    public void add_OnFireNiceEvent(EventHandler<SomeStandardArgs> handler)
    {
        Delegate.Combine(_OnFireNiceEvent, handler);
    }

    public void remove_OnFireNiceEvent(EventHandler<SomeStandardArgs> handler)
    {
        Delegate.Remove(_OnFireNiceEvent, handler);
    }

    public event EventHandler<SomeStandardArgs> OnFireNiceEvent
    {
        add
        {
            add_OnFireNiceEvent(value)
        }
        remove
        {
            remove_OnFireNiceEvent(value)

        }
    }

The compiler generates a private delegate variable which is not visible to the class namespace in which it is generated. That delegate is what is used for subscription management and late binding participation, and the public facing interface is the familiar += and -= operators we have all come to know and love : )

You can customize the code for the add/remove handlers by changing the scope of the FireNiceEvent delegate to protected. This now allows developers to add custom hooks to the hooks, such as logging or security hooks. This really makes for some very powerful features that now allows for customized accessibility to subscription based on user roles, etc. Can you do that with lambdas? (Actually you can by custom compiling expression trees, but that's beyond the scope of this response).

To address a couple of points from some of the responses here:

• There really is no difference in the 'brittleness' between changing the args list in Action<T> and changing the properties in a class derived from EventArgs. Either will not only require a compile change, they will both change a public interface and will require versioning. No difference.

• With respect to which is an industry standard, that depends on where this is being used and why. Action<T> and such is often used in IoC and DI, and event is often used in message routing such as GUI and MQ type frameworks. Note that I said often, not always.

• Delegates have different lifetimes than lambdas. One also has to be aware of capture... not just with closure, but also with the notion of 'look what the cat dragged in'. This does affect memory footprint/lifetime as well as management a.k.a. leaks.

One more thing, something I referenced earlier... the notion of late binding. You will often see this when using framework like LINQ, regarding when a lambda becomes 'live'. That is very different than late binding of a delegate, which can happen more than once (i.e. the lambda is always there, but binding occurs on demand as often as is needed), as opposed to a lambda, which once it occurs, its done -- the magic is gone, and the method(s)/property(ies) will always bind. Something to keep in mind.

In my case, I had to use different certificates for different git repositories.

Follow steps below (If you have a certificate of your repository, you can read from step 5)

1. Go to remote repository's site. Ex: github.com, bitbucket.org, tfs.example...

2. Click Lock icon on the upper left side and click Certificate.

3. Go to Certification Path tab and double click to .. Root Certificate

4. Go to Details tab and click Copy to file.

5. Export/Copy certificate to wherever you want. Ex: C:\certs\example.cer

6. Open git bash at your local repository folder and type:

   $ git config http.sslCAInfo "C:\certs\example.cer"

Now you can use different certificates for each repository.

Remember, calling with the --global parameter will also change the certificates of git repositories in other folders, so you should not use the --global parameter when executing this command.

img {
  max-width: 100%;
}

Should set the image to take up 100% of its containing element.

When the local git projects are cloned in eclipse and are viewable in git perspective but not in package explorer (workspace), the following steps worked for me:

• Select the repository in git perspective
• Right click and select import projects

ok I finally found a good solution:

$('iframe').load(function() {
    this.style.height =
    this.contentWindow.document.body.offsetHeight + 'px';
});

Because some browsers (older Safari and Opera) report onload completed before CSS renders you need to set a micro Timeout and blank out and reassign the iframe's src.

$('iframe').load(function() {
    setTimeout(iResize, 50);
    // Safari and Opera need a kick-start.
    var iSource = document.getElementById('your-iframe-id').src;
    document.getElementById('your-iframe-id').src = '';
    document.getElementById('your-iframe-id').src = iSource;
});
function iResize() {
    document.getElementById('your-iframe-id').style.height = 
    document.getElementById('your-iframe-id').contentWindow.document.body.offsetHeight + 'px';
}

I had the same problem . Same configuration settings and same warning message . What worked for me was : Changing the order of the entries .

• I put the entries for the log configuration [ the context param and the listener ] on the top of the file [ before the entry for the applicationContext.xml ] and it worked .

The Order matters , i guess .

using a variable

$array_IN=Dev_Table::where('id',1)->select('tabl2_id')->get();
$sel_table2=Dev_Table2::WhereIn('id',$array_IN)->get();

You can "style echo" with adding new HTML code.

echo '<span class="city">' . $ip['cityName'] . '</span>';

If you want it cross-browser, your best bet is to do it on the server. You could have an API that takes a file URL and returns you the EXIF data; PHP has a module for that.

This could be done using Ajax so it would be seamless to the user. If you don't care about cross-browser compatibility, and can rely on HTML5 file functionality, look into the library JsJPEGmeta that will allow you to get that data in native JavaScript.

Try adding the following method to your app's root view controller:

- (BOOL)prefersStatusBarHidden
    {
        return YES;
    }

You have a concrete example of a Student and a MessageBoard. The Student registers by adding itself to the list of Observers that want to be notified when a new Message is posted to the MessageBoard. When a Message is added to the MessageBoard, it iterates over its list of Observers and notifies them that the event occurred.

Think Twitter. When you say you want to follow someone, Twitter adds you to their follower list. When they sent a new tweet in, you see it in your input. In that case, your Twitter account is the Observer and the person you're following is the Observable.

The analogy might not be perfect, because Twitter is more likely to be a Mediator. But it illustrates the point.

Try using some shell magic: %%sh %%sh pip install geocoder let me know if it works, thanks

I mixed up some comments above and that resolved my problem

I. Project Cleanup

1. In the project navigator, select your project
2. Select your target
3. Remove all libPods*.a in Build Phases > Link Binary With Libraries

II. Clean build folder

In XCode: Menu Bar ? Product ? Product -> Clean build Folder

III. Update cocapods

Run pod update

Use the z modifier:

size_t x = ...;
ssize_t y = ...;
printf("%zu\n", x);  // prints as unsigned decimal
printf("%zx\n", x);  // prints as hex
printf("%zd\n", y);  // prints as signed decimal

To make the text portion of a ComboBox non-editable, set the DropDownStyle property to "DropDownList". The ComboBox is now essentially select-only for the user. You can do this in the Visual Studio designer, or in C# like this:

stateComboBox.DropDownStyle = ComboBoxStyle.DropDownList;

Link to the documentation for the ComboBox DropDownStyle property on MSDN.

That's the main concept. Have fun ;)

NSURL *url = [NSURL URLWithString:@"http://example.com/yourImage.png"];
NSData *data = [NSData dataWithContentsOfURL:url];
NSString *path = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
path = [path stringByAppendingString:@"/yourLocalImage.png"];
[data writeToFile:path atomically:YES];

First Method: (Tested)

Code in .aspx.cs:

 protected void Page_Load(object sender, EventArgs e)
    {
        ddl.SelectedIndexChanged += new EventHandler(ddl_SelectedIndexChanged);
        if (!Page.IsPostBack)
        {
            ddl.Attributes.Add("onchange", "CalcTotalAmt();");
        }
    }

    protected void ddl_SelectedIndexChanged(object sender, EventArgs e)
    {
       //Your Code
    }

JavaScript function: return true from your JS function

   function CalcTotalAmt() 
 {
//Your Code
 }

.aspx code:

<asp:DropDownList ID="ddl" runat="server"  AutoPostBack="true">
        <asp:ListItem Text="a" Value="a"></asp:ListItem>
         <asp:ListItem Text="b" Value="b"></asp:ListItem>
        </asp:DropDownList>

Second Method: (Tested)

Code in .aspx.cs:

protected void Page_Load(object sender, EventArgs e)
        {
            if (Request.Params["__EVENTARGUMENT"] != null && Request.Params["__EVENTARGUMENT"].Equals("ddlchange"))
                ddl_SelectedIndexChanged(sender, e);
            if (!Page.IsPostBack)
            {
                ddl.Attributes.Add("onchange", "CalcTotalAmt();");
            }
        }

        protected void ddl_SelectedIndexChanged(object sender, EventArgs e)
        {
            //Your Code
        }

JavaScript function: return true from your JS function

function CalcTotalAmt() {
         //Your Code
     __doPostBack("ctl00$MainContent$ddl","ddlchange");
 }

.aspx code:

<asp:DropDownList ID="ddl" runat="server"  AutoPostBack="true">
        <asp:ListItem Text="a" Value="a"></asp:ListItem>
         <asp:ListItem Text="b" Value="b"></asp:ListItem>
        </asp:DropDownList>

Just by one line-

var select_button_text = $('#SelectQButton option:selected')
                .toArray().map(item => item.text);

Output: ["text1", "text2"]

var select_button_text = $('#SelectQButton option:selected')
                .toArray().map(item => item.value);

Output: ["value1", "value2"]

If you use .join()

var select_button_text = $('#SelectQButton option:selected')
                .toArray().map(item => item.text).join();

Output: text1,text2,text3

I put together a quick solution for anyone wanting to create hover popups without CSS using the onmouseover and onmouseout behaviors.

http://jsfiddle.net/Lk9w1mkv/

<div style="position:relative;width:100px;background:#ddffdd;overflow:hidden;" onmouseover="this.style.overflow='';" onmouseout="this.style.overflow='hidden';">first hover<div style="width:100px;position:absolute;top:5px;left:110px;background:white;border:1px solid gray;">stuff inside</div></div>

Slightly different approach:

bool A() {...}
bool B() {...}
bool C() {...}

int main(void)
{
  /**
   * Declare an array of pointers to functions returning bool
   * and initialize with A, B, and C
   */
  bool (*farr[])() = {A, B, C};
  ...
  /**
   * Call A, B, or C based on the value of i
   * (assumes i is in range of array)
   */
  if (farr[i]()) // or (*farr[i])()
  {
    ...
  }
  ...
}

Do you see anything wrong with the code?

Yes. Why are you adding the three fields together before you compare them?

I would probably do something like this: (assuming the fields are in the order you wish to sort them in)

@Override public int compare(final Report record1, final Report record2) {
    int c;
    c = record1.getReportKey().compareTo(record2.getReportKey());
    if (c == 0)
       c = record1.getStudentNumber().compareTo(record2.getStudentNumber());
    if (c == 0)
       c = record1.getSchool().compareTo(record2.getSchool());
    return c;
}

Are you searching for this:

int c = some_ascii_character;

Or just converting without assignment:

(int)some_aschii_character;

In addition to the generic device (or "Any iOS Device" in newer versions of Xcode) mentioned in the other answers, it is possible that the "Archive" action is not selected for the current target in the scheme.

To view and edit at the current scheme, select Product > Schemes > Edit Scheme... (Cmd+<), then make sure that the "Archive" action is checked in the line corresponding to the desired target.

In the image below, Archive is not checked and the Archive action is greyed out in the Product menu. Checking the indicated checkbox fixed the issue for me.

To prohibit declarations of variables with the same name.

e.g. int i = 0, goto;

i do your code .i can run but i need modify two places:

1. name="android:indeterminateDrawable" instead of android:progressDrawable

2. modify name attrs.xml ---> styles.xml

// This worked for me.
<form  name="myForm" class="css-form" novalidate ng-submit="Save(myForm.$invalid)">
<input type="text" name="uName" ng-model="User.Name" required/>
<span ng-show="User.submitted && myForm.uName.$error.required">Name is required.</span>
<input ng-click="User.submitted=true" ng-disabled="User.submitted && tForm.$invalid" type="submit" value="Save" />
</form>
// in controller
$scope.Save(invalid)
{
if(invalid) return;
// save form
}

Using Visual Studio

1. Attach a debugger to the process (e.g. start with debugging or Debug > Attach to process)
2. While debugging, show the Modules window (Debug > Windows > Modules)

This gives details about each assembly, app domain and has a few options to load symbols (i.e. pdb files that contain debug information).

Using Process Explorer

If you want an external tool you can use the Process Explorer (freeware, published by Microsoft)

Click on a process and it will show a list with all the assemblies used. The tool is pretty good as it shows other information such as file handles etc.

Programmatically

Check this SO question that explains how to do it.

Without telling us what language this dll/assembly is from, we can only guess.

So how about .NET Reflector

This is actually compiler dependent, and not supported by any standard.

Here however you have a macro implementation that does the count:

#define PP_NARG(...) \
         PP_NARG_(__VA_ARGS__,PP_RSEQ_N())
#define PP_NARG_(...) \
         PP_ARG_N(__VA_ARGS__)
#define PP_ARG_N( \
          _1, _2, _3, _4, _5, _6, _7, _8, _9,_10, \
         _11,_12,_13,_14,_15,_16,_17,_18,_19,_20, \
         _21,_22,_23,_24,_25,_26,_27,_28,_29,_30, \
         _31,_32,_33,_34,_35,_36,_37,_38,_39,_40, \
         _41,_42,_43,_44,_45,_46,_47,_48,_49,_50, \
         _51,_52,_53,_54,_55,_56,_57,_58,_59,_60, \
         _61,_62,_63,N,...) N
#define PP_RSEQ_N() \
         63,62,61,60,                   \
         59,58,57,56,55,54,53,52,51,50, \
         49,48,47,46,45,44,43,42,41,40, \
         39,38,37,36,35,34,33,32,31,30, \
         29,28,27,26,25,24,23,22,21,20, \
         19,18,17,16,15,14,13,12,11,10, \
         9,8,7,6,5,4,3,2,1,0

/* Some test cases */


PP_NARG(A) -> 1
PP_NARG(A,B) -> 2
PP_NARG(A,B,C) -> 3
PP_NARG(A,B,C,D) -> 4
PP_NARG(A,B,C,D,E) -> 5
PP_NARG(1,2,3,4,5,6,7,8,9,0,
         1,2,3,4,5,6,7,8,9,0,
         1,2,3,4,5,6,7,8,9,0,
         1,2,3,4,5,6,7,8,9,0,
         1,2,3,4,5,6,7,8,9,0,
         1,2,3,4,5,6,7,8,9,0,

Starting in ios 6 you can set an attributed string in the UILabel:

NSString *labelText = @"some text"; 
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:labelText];
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
[paragraphStyle setLineSpacing:40];
[attributedString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, [labelText length])];
cell.label.attributedText = attributedString ;

Maybe not the most efficient way. But you could convert the list into a vector.

#include <list>
#include <vector>

list<Object> myList;

vector<Object> myVector(myList.begin(), myList.end());

Then access the vector using the [x] operator.

auto x = MyVector[0];

You could put that in a helper function:

#include <memory>
#include <vector>
#include <list>

template<class T>
shared_ptr<vector<T>> 
ListToVector(list<T> List) {
shared_ptr<vector<T>> Vector {
        new vector<string>(List.begin(), List.end()) }
return Vector;
}

Then use the helper funciton like this:

auto MyVector = ListToVector(Object);
auto x = MyVector[0];

This answer is for those seeking to just change the value of a data-attribute

The suggested will not change the value of your Jquery data-attr correctly as @adeneo has stated. For some reason though, I'm not seeing him (or any others) post the correct method for those seeking to update their data-attr. The answer that @Lucas Willems has posted may be the answer to problem Brian Tompsett - ??? is having, but it's not the answer to the inquiry that may be bringing other users here.

Quick answer in regards to original inquiry statement

-To update data-attr

$('#ElementId').attr('data-attributeTitle',newAttributeValue);

Easy mistakes* - there must be "data-" at the beginning of your attribute you're looking to change the value of.

Arrays.sort(yourarray, new Comparator() {
    public int compare(Object o1, Object o2) {
        String[] elt1 = (String[])o1;
        String[] elt2 = (String[])o2;
        return elt1[0].compareTo(elt2[0]);
    }
});

In my case, I was getting error connecting to AWS Gov Postgres RDS. There is a separate link for GOV RDS CA certs- https://s3.us-gov-west-1.amazonaws.com/rds-downloads/rds-combined-ca-us-gov-bundle.pem

Add this pem certs to cacerts of java. You can use below script.

------WINDOWDS STEPS-------

1. Use VSCODE editor and install openssl, keytool plugins
2. create a dir in C:/rds-ca
3. place 'cacerts' file and below script file - 'addCerts.sh' inside dir 'rd-ca'
4. run from vscode: 4.1 cd /c/rds-ca/ 4.2 ./addCerts.sh
5. Copy cacerts to ${JAVA_HOME}/jre/lib/security

Script code:

#!/usr/bin/env sh

OLDDIR="$PWD"

CACERTS_FILE=cacerts

cd /c/rds-ca

echo "Downloading RDS certificates..."

curl  https://s3.us-gov-west-1.amazonaws.com/rds-downloads/rds-combined-ca-us-gov-bundle.pem > rds-combined-ca-bundle.pem

csplit -sk rds-combined-ca-bundle.pem "/-BEGIN CERTIFICATE-/" "{$(grep -c 'BEGIN CERTIFICATE' rds-combined-ca-bundle.pem | awk '{print $1 - 2}')}"

for CERT in xx*; do
    # extract a human-readable alias from the cert
    ALIAS=$(openssl x509 -noout -text -in $CERT |
                   perl -ne 'next unless /Subject:/; s/.*CN=//; print')
    echo "importing $ALIAS"
    
    keytool -import \
            -keystore  $CACERTS_FILE \
            -storepass changeit -noprompt \
            -alias "$ALIAS" -file $CERT
done

cd "$OLDDIR"
echo "$NEWDIR"

Just an update.

Now if it's a github repository then using just a github shorthand is enough if you do not mind the version of course.

Important Note: As of mid-2018, the process to get twitter API tokens became a lot more bureaucratic. It has taken me over one working week to be provided a set of API tokens, and this is for an open source project for you guys and girls with over 1.2 million installations on Packagist and 1.6k stars on Github, which theoretically should be higher priority.

If you are tasked with working with the twitter API for your work, you must take this potentially extremely long wait-time into account. Also consider other social media avenues like Facebook or Instagram and provide these options, as the process for retrieving their tokens is instant.

So you want to use the Twitter v1.1 API?

Note: the files for these are on GitHub.

Version 1.0 will soon be deprecated and unauthorised requests won't be allowed. So, here's a post to help you do just that, along with a PHP class to make your life easier.

1. Create a developer account: Set yourself up a developer account on Twitter

You need to visit the official Twitter developer site and register for a developer account. This is a free and necessary step to make requests for the v1.1 API.

2. Create an application: Create an application on the Twitter developer site

What? You thought you could make unauthenticated requests? Not with Twitter's v1.1 API. You need to visit http://dev.twitter.com/apps and click the "Create Application" button.

On this page, fill in whatever details you want. For me, it didn't matter, because I just wanted to make a load of block requests to get rid of spam followers. The point is you are going to get yourself a set of unique keys to use for your application.

So, the point of creating an application is to give yourself (and Twitter) a set of keys. These are:

• The consumer key
• The consumer secret
• The access token
• The access token secret

There's a little bit of information here on what these tokens for.

3. Create access tokens: You'll need these to make successful requests

OAuth requests a few tokens. So you need to have them generated for you.

Click "create my access token" at the bottom. Then once you scroll to the bottom again, you'll have some newly generated keys. You need to grab the four previously labelled keys from this page for your API calls, so make a note of them somewhere.

4. Change access level: You don't want read-only, do you?

If you want to make any decent use of this API, you'll need to change your settings to Read & Write if you're doing anything other than standard data retrieval using GET requests.

Choose the "Settings" tab near the top of the page.

Give your application read / write access, and hit "Update" at the bottom.

You can read more about the applications permission model that Twitter uses here.

5. Write code to access the API: I've done most of it for you

I combined the code above, with some modifications and changes, into a PHP class so it's really simple to make the requests you require.

This uses OAuth and the Twitter v1.1 API, and the class I've created which you can find below.

require_once('TwitterAPIExchange.php');

/** Set access tokens here - see: https://dev.twitter.com/apps/ **/
$settings = array(
    'oauth_access_token' => "YOUR_OAUTH_ACCESS_TOKEN",
    'oauth_access_token_secret' => "YOUR_OAUTH_ACCESS_TOKEN_SECRET",
    'consumer_key' => "YOUR_CONSUMER_KEY",
    'consumer_secret' => "YOUR_CONSUMER_SECRET"
);

Make sure you put the keys you got from your application above in their respective spaces.

Next you need to choose a URL you want to make a request to. Twitter has their API documentation to help you choose which URL and also the request type (POST or GET).

/** URL for REST request, see: https://dev.twitter.com/docs/api/1.1/ **/
$url = 'https://api.twitter.com/1.1/blocks/create.json';
$requestMethod = 'POST';

In the documentation, each URL states what you can pass to it. If we're using the "blocks" URL like the one above, I can pass the following POST parameters:

/** POST fields required by the URL above. See relevant docs as above **/
$postfields = array(
    'screen_name' => 'usernameToBlock', 
    'skip_status' => '1'
);

Now that you've set up what you want to do with the API, it's time to make the actual request.

/** Perform the request and echo the response **/
$twitter = new TwitterAPIExchange($settings);
echo $twitter->buildOauth($url, $requestMethod)
             ->setPostfields($postfields)
             ->performRequest();

And for a POST request, that's it!

For a GET request, it's a little different. Here's an example:

/** Note: Set the GET field BEFORE calling buildOauth(); **/
$url = 'https://api.twitter.com/1.1/followers/ids.json';
$getfield = '?username=J7mbo';
$requestMethod = 'GET';
$twitter = new TwitterAPIExchange($settings);
echo $twitter->setGetfield($getfield)
             ->buildOauth($url, $requestMethod)
             ->performRequest();     

Final code example: For a simple GET request for a list of my followers.

$url = 'https://api.twitter.com/1.1/followers/list.json';
$getfield = '?username=J7mbo&skip_status=1';
$requestMethod = 'GET';
$twitter = new TwitterAPIExchange($settings);
echo $twitter->setGetfield($getfield)
             ->buildOauth($url, $requestMethod)
             ->performRequest();  

I've put these files on GitHub with credit to @lackovic10 and @rivers! I hope someone finds it useful; I know I did (I used it for bulk blocking in a loop).

Also, for those on Windows who are having problems with SSL certificates, look at this post. This library uses cURL under the hood so you need to make sure you have your cURL certs set up probably. Google is also your friend.

use a simple formula: WHO.WHAT = VALUE

where,

WHO is the element in the storyboard you want to make changes to for eg. label

WHAT is the property of that element you wish to change for eg. text

VALUE is the change that you wish to be displayed

for eg. if I want to change the text from story text to You see a fork in the road in the label as shown in screenshot 1

In this case, our WHO is the label (element in the storyboard), WHAT is the text (property of element) and VALUE will be You see a fork in the road

so our final code will be as follows: Final code

screenshot 1 changes to screenshot 2 once the above code is executed.

I hope this solution helps you solve your issue. Thank you!

This NSString category uses the NSXMLParser to accurately remove any HTML tags from an NSString. This is a single .m and .h file that can be included into your project easily.

https://gist.github.com/leighmcculloch/1202238

You then strip html by doing the following:

Import the header:

#import "NSString_stripHtml.h"

And then call stripHtml:

NSString* mystring = @"<b>Hello</b> World!!";
NSString* stripped = [mystring stripHtml];
// stripped will be = Hello World!!

This also works with malformed HTML that technically isn't XML.

I haven't used code to pull .apk file from mobile but i have been using software to extract .apk file from mobile and software i have used are below with google play link:

1. ES File Explorer File Manager
2. ASTRO Cloud & File Manager 3.Software Data Cable

Hope it helps You.

In my case, an Ubuntu system, in ports.conf I had

NameVirtualHost *:80
NameVirtualHost 192.168.1.79
Listen 80

And then, inside , I had

NameVirtualHost *:443
Listen 443

All I had to do was remove the line NameVirtualHost 192.168.1.79. Restarted apache and problem solved.

You can use the .bind method to pre-build the parameters to the handleChange method. It would be something like:

  var Hello = React.createClass({
    getInitialState: function() {
        return {input1:0, 
                input2:0};
    },
    render: function() {
      var total = this.state.input1 + this.state.input2;
      return (
        <div>{total}<br/>
          <input type="text" value={this.state.input1} 
                             onChange={this.handleChange.bind(this, 'input1')} />
          <input type="text" value={this.state.input2} 
                             onChange={this.handleChange.bind(this, 'input2')} />
        </div>
      );
    },
    handleChange: function (name, e) {
      var change = {};
      change[name] = e.target.value;
      this.setState(change);
    }
  });

  React.renderComponent(<Hello />, document.getElementById('content'));

(I also made total be computed at render time, as it is the recommended thing to do.)

Elaborating on previous answer by Pir Fahim, he's right but i'm using selectedItem.Text (only way to make it work to me)

Use the SelectedIndexChanged() event to store the data somewhere. In my case, i usually fill a custom class, something like:

class myItem {
    string name {get; set;}
    string price {get; set;}
    string desc {get; set;}
}

private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
     myItem selected_item = new myItem();
     selected_item.name  = listBox1.SelectedItem.Text;
     Retrieve (selected_item.name);
}

And then you can retrieve the rest of data from a List of "myItems"..

myItem Retrieve (string wanted_item) {
    foreach (myItem item in my_items_list) {
        if (item.name == wanted_item) {
               // This is the selected item
               return item; 
        }
    }
    return null;
}

<div *ngIf="currentStatus !== ('status1' || 'status2' || 'status3' || 'status4')">

I believe you can pass in event into the function inline which will be the event object for the raised event in W3C compliant browsers (i.e. older versions of IE will still require detection inside of your event handler function to look at window.event).

A quick example.

function sayHi(e) {_x000D_
   e.preventDefault();_x000D_
   alert("hi");_x000D_
}

<a href="http://google.co.uk" onclick="sayHi(event);">Click to say Hi</a>

1. Run it as is and notice that the link does no redirect to Google after the alert.
2. Then, change the event passed into the onclick handler to something else like e, click run, then notice that the redirection does take place after the alert (the result pane goes white, demonstrating a redirect).

use curl php library: http://php.net/manual/en/book.curl.php

direct example: CURL_EXEC:

<?php
// create a new cURL resource
$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);

// grab URL and pass it to the browser
curl_exec($ch);

// close cURL resource, and free up system resources
curl_close($ch);
?>

For example, you want to sync table todoTable from MySql to Sqlite

First, create one column name version (type INT) in todoTable for both Sqlite and MySql

Second, create a table name database_version with one column name currentVersion(INT)

In MySql, when you add a new item to todoTable or update item, you must upgrade the version of this item by +1 and also upgrade the currentVersion

In Android, when you want to sync (by manual press sync button or a service run with period time):

You will send the request with the Sqlite currentVersion (currently it is 1) to server.
Then in server, you find what item in MySql have version value greater than Sqlite currentVersion(1) then response to Android (in this example the item 3 with version 2 will response to Android)

In SQLite, you will add or update new item to todoTable and upgrade the currentVersion

If you are using jupyter notebook, You can remove it like this:

pip uninstall notebook

You should use conda uninstall if you installed it with conda.

l = [9.0, 0.052999999999999999, 0.032575399999999997, 0.010892799999999999, 0.055702500000000002, 0.079330300000000006]

Python 2:

print ', '.join('{:0.2f}'.format(i) for i in l)

Python 3:

print(', '.join('{:0.2f}'.format(i) for i in l))

Output:

9.00, 0.05, 0.03, 0.01, 0.06, 0.08

Use struct.pack to convert the integer values into binary bytes, then write the bytes. E.g.

newFile.write(struct.pack('5B', *newFileBytes))

However I would never give a binary file a .txt extension.

The benefit of this method is that it works for other types as well, for example if any of the values were greater than 255 you could use '5i' for the format instead to get full 32-bit integers.

Set the GroupName property of both radio buttons to the same value. You could also try using a RadioButtonGroup, which does this for you automatically.

It's more standard to use the format yyyy-mm-dd hh:mm:ss (IE: 2009-06-23 19:30:20)

Using that you won't have to worry about the format of the date (MM/DD/YYYY or DD/MM/YYYY). It will work with all of them.

If java command is working and getting problem with javac. then first check in jdk's bin directory javac.exe file is there or not. If javac.exe file is exist then set JAVA_HOME as System variable.

Not with pure CSS. The closest equivalent is this:

.class1, .class2 {
    some stuff
}

.class2 {
    some more stuff
}

The only classes that can be static are inner classes. The following code works just fine:

public class whatever {
    static class innerclass {
    }
}

The point of static inner classes is that they don't have a reference to the outer class object.

For me it worked, by removing the jars in question from the war. With Maven, I just had to exclude for example

        <version>${resteasy.version}</version>

The Equals method does a reference comparison - if the arrays are different objects, this will indeed return false.

To check if the arrays contain identical values (and in the same order), you will need to iterate over them and test equality on each.

If using @Rule, the exception set is applied to all the test methods in the Test class.

Just subtract the two dates:

select date '2000-01-02' - date '2000-01-01' as dateDiff
from dual;

The result will be the difference in days.

In C++11 you can use std::to_string:

std::string var = "sometext" + std::to_string(somevar) + "sometext" + std::to_string(somevar);  

I came to this question via Google, searching for a way to convert an already loaded image to grayscale.

Here is a way to do it with SciPy:

import scipy.misc
import scipy.ndimage

# Load an example image
# Use scipy.ndimage.imread(file_name, mode='L') if you have your own
img = scipy.misc.face()

# Convert the image
R = img[:, :, 0]
G = img[:, :, 1]
B = img[:, :, 2]
img_gray = R * 299. / 1000 + G * 587. / 1000 + B * 114. / 1000

# Show the image
scipy.misc.imshow(img_gray)

<textarea name="myMessage" onkeyup="wordcount(this.value)"></textarea>
<script type="text/javascript">
var cnt;
function wordcount(count) {
var words = count.split(/\s/);
cnt = words.length;
var ele = document.getElementById('w_count');
ele.value = cnt;
}
document.write("<input type=text id=w_count size=4 readonly>");
</script>

Following is how I draw a checkbox in a table!

| Checkbox Experiments | [ ] unchecked header  | [x] checked header  |
| ---------------------|:---------------------:|:-------------------:|
| checkbox             | [ ] row               | [x] row             |

Displays like this:

As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.

Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash is incorrect and should have been callbackOnLocationHash (note the mis-spelling of "Location").

This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.

Example:

interface TextOptions {
    alignment?: string;
    color?: string;
    padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'

But I meant to do that

There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes

Type-checking only some properties

Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v or v as T) do not check for extra properties, so you can use them in place of a type annotation:

interface Options {
    x?: string;
    y?: number;
}

// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;

These properties and maybe more

Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking

Before

interface Model {
  name: string;
}
function createModel(x: Model) { ... }

// Error
createModel({name: 'hello', length: 100});

After

interface Model {
  name: string;
  [others: string]: any;
}
function createModel(x: Model) { ... }

// OK
createModel({name: 'hello', length: 100});

This is a dog or a cat or a horse, not sure yet

interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }

let x: Animal;
if(...) {
  x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
  x = { move: 'catwalk', meow: 'mrar' };
} else {
  x = { move: 'gallop', neigh: 'wilbur' };
}

Two good solutions come to mind here

Specify a closed set for x

// Removes all errors
let x: Dog|Cat|Horse;

or Type assert each thing

// For each initialization
  x = { move: 'doggy paddle', woof: 'bark' } as Dog;

This type is sometimes open and sometimes not

A clean solution to the "data model" problem using intersection types:

interface DataModelOptions {
  name?: string;
  id?: number;
}
interface UserProperties {
  [key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
 /* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
 /* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });
// Error, 'ID' is not correct (should be 'id')
findDataModel({ ID: 32 });

Further to the previous answers, the first thing I always do when thinking of issues like this is to create a small test application. Inside this app, perform some timing test for both scenarios and see for yourself which is quicker.

IMHO, appending 500+ string entries should definitely use StringBuilder.

RPC Stubs

• Basically, a client-side stub is a procedure that looks to the client as if it were a callable server procedure.
• A server-side stub looks to the server as if it's a calling client.
• The client program thinks it is calling the server; in fact, it's calling the client stub.
• The server program thinks it's called by the client; in fact, it's called by the server stub.
• The stubs send messages to each other to make the RPC happen.

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

Here is a modification for the prev. answer. The main difference is when the user is not authenticated, it uses the original "HandleUnauthorizedRequest" method to redirect to login page:

   protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
    {

        if (filterContext.HttpContext.User.Identity.IsAuthenticated) {

            filterContext.Result = new RedirectToRouteResult(
                        new RouteValueDictionary(
                            new
                            {
                                controller = "Account",
                                action = "Unauthorised"
                            })
                        );
        }
        else
        {
             base.HandleUnauthorizedRequest(filterContext);
        }
    }

It is safer and neater to use an explicit starting point '19000101'

create function dbo.fnDateTime2FromParts(@Year int, @Month int, @Day int, @Hour int, @Minute int, @Second int, @Nanosecond int)
returns datetime2
as
begin
    -- Note! SQL Server 2012 includes datetime2fromparts() function
    declare @output datetime2 = '19000101'
    set @output = dateadd(year      , @Year - 1900  , @output)
    set @output = dateadd(month     , @Month - 1    , @output)
    set @output = dateadd(day       , @Day - 1      , @output)
    set @output = dateadd(hour      , @Hour         , @output)
    set @output = dateadd(minute    , @Minute       , @output)
    set @output = dateadd(second    , @Second       , @output)
    set @output = dateadd(ns        , @Nanosecond   , @output)
    return @output
end

I think this is the solution you were looking for

<button type="submit" onclick="window.location.href='file.doc'">Download!</button>

I hade a case where my Javascript generated a CSV file. Since there is no remote URL to download it I use the following implementation.

    window.location.href = window.URL.createObjectURL(blob);

In principle, you can pass any reformatting function to the labels parameter:

+ scale_y_continuous(labels = function(x) paste0(x*100, "%")) # Multiply by 100 & add %  

Or

+ scale_y_continuous(labels = function(x) paste0(x, "%")) # Add percent sign 

Reproducible example:

library(ggplot2)
df = data.frame(x=seq(0,1,0.1), y=seq(0,1,0.1))

ggplot(df, aes(x,y)) + 
  geom_point() +
  scale_y_continuous(labels = function(x) paste0(x*100, "%"))

Using file extension and getimagesize function to detect if uploaded file has right format is just the entry level check and it can simply bypass by uploading a file with true extension and some byte of an image header but wrong content.

for being secure and safe you may make thumbnail/resize (even with original image sizes) the uploaded picture and save this version instead the uploaded one. Also its possible to get uploaded file content and search it for special character like <?php to find the file is image or not.

For those running into this issue (granted 4 years after this post was made) while running Mac OS High Sierra - the steps outlined here solved the problem for me. Essentially just outlines uninstalling and reinstalling brew.

https://medium.com/@mrkdsgn/brew-error-on-macos-high-sierra-check-you-have-permission-to-write-to-usr-local-e8bd1c6a22d4

After running those steps, brew link worked like a charm!

I used google colab to run my models and everything was perfect untill i used inline tesorboard. With tensorboard inline, I had the same issue of "Module 'tensorflow' has no attribute 'contrib'".

It was able to run training when rebuild and reinstall the model using setup.py(research folder) after initialising tensorboard.

In a shell you can use the -z operator which is True if the length of string is zero.

A simple one-liner to set default MY_VAR if it's not set, otherwise optionally you can display the message:

[[ -z "$MY_VAR" ]] && MY_VAR="default"
[[ -z "$MY_VAR" ]] && MY_VAR="default" || echo "Variable already set."

npm install serve-index

var express    = require('express')
var serveIndex = require('serve-index')
var path = require('path')
var serveStatic = require('serve-static')
var app = express()
var port = process.env.PORT || 3000;
/**for files */
app.use(serveStatic(path.join(__dirname, 'public')));
/**for directory */
app.use('/', express.static('public'), serveIndex('public', {'icons': true}))

// Listen
app.listen(port,  function () {
  console.log('listening on port:',+ port );
})

In order to get current date as integer(10 digit number), you need to divide the long returned from new Date().getTime() by 1000.

This will be in int range and is good until 18 Jan 2038.

Below is extension method to check for null if you want to sort on child property of a keySelector.

public static IOrderedEnumerable<T> NullableOrderBy<T>(this IEnumerable<T> list, Func<T, object> parentKeySelector, Func<T, object> childKeySelector)
{
    return list.OrderBy(v => parentKeySelector(v) != null ? 0 : 1).ThenBy(childKeySelector);
}

And simple use it like:

var sortedList = list.NullableOrderBy(x => x.someObject, y => y.someObject?.someProperty);

Angular is based on observable instead of promise base as of angularjs 1.x, so when we try to get data using http it returns observable instead of promise, like you did

 return this.http
      .get(this.configEndPoint)
      .map(res => res.json());

then to get data and show on view we have to convert it into desired form using RxJs functions like .map() function and .subscribe()

.map() is used to convert the observable (received from http request)to any form like .json(), .text() as stated in Angular's official website,

.subscribe() is used to subscribe those observable response and ton put into some variable so from which we display it into the view

this.myService.getConfig().subscribe(res => {
   console.log(res);
   this.data = res;
});

Subversion implicitly has the remote repository associated with it at all times. Git, on the other hand, allows many "remotes", each of which represents a single remote place you can push to or pull from.

You need to add a remote for the GitHub repository to your local repository, then use git push ${remote} or git pull ${remote} to push and pull respectively - or the GUI equivalents.

Pro Git discusses remotes here: http://git-scm.com/book/ch2-5.html

The GitHub help also discusses them in a more "task-focused" way here: http://help.github.com/remotes/

Once you have associated the two you will be able to push or pull branches.

Up to XP and Server 2003, you can make use of another included tool (VBScript) - the following two scripts do the job you want.

First, getpwd.cmd:

@echo off
<nul: set /p passwd=Password: 
for /f "delims=" %%i in ('cscript /nologo getpwd.vbs') do set passwd=%%i
echo.

Then, getpwd.vbs:

Set oScriptPW = CreateObject("ScriptPW.Password")
strPassword = oScriptPW.GetPassword()
Wscript.StdOut.WriteLine strPassword

The getpwd.vbs simply uses the password object to input the password from the user and then print it to standard output (the next paragraph will explain why that doesn't show up in the terminal).

The getpwd.cmd command script is a bit trickier but it basically works as follows.

The effect of the "<nul: set /p passwd=Password: " command is to output the prompt with no trailing newline character - it's a sneaky way to emulate the "echo -n" command from the bash shell. It sets passwd to an empty string as an irrelevant side effect and doesn't wait for input since it's taking its input from the nul: device.

The "for /f "delims=" %%i in ('cscript /nologo getpwd.vbs') do set passwd=%%i" statement is the trickiest bit. It runs the VBScript with no Microsoft "advertising", so that the only line output is the password (from the VBscript "Wscript.StdOut.WriteLine strPassword".

Setting the delimiters to nothing is required to capture an entire input line with spaces, otherwise you just get the first word. The "for ... do set ..." bit sets passwd to be the actual password output from the VBScript.

Then we echo a blank line (to terminate the "Password: " line) and the password will be in the passwd environment variable after the code has run.

Now, as mentioned, scriptpw.dll is available only up to XP/2003. In order to rectify this, you can simply copy the scriptpw.dll file from the Windows\System32 folder of an XP/2003 system to the Winnt\System32 or Windows\System32 folder on your own system. Once the DLL has been copied, you will need to register it by running:

regsvr32 scriptpw.dll

To successfully register the DLL on Vista and later, you will need administrator privileges. I haven't examined the legality of such a move so cave lector.

If you're not overly keen on trying to track down and register older DLL files (for convenience or legal reasons), there is another way. Later versions of Windows (the ones that don't have the required DLL) should have Powershell available to you.

And, in fact, you really should consider upgrading your scripts to use it fully since it's a much more capable scripting language than cmd.exe. However, if you want to keep the bulk of your code as cmd.exe scripts (such as if you have a lot of code that you don't want to convert), you can use the same trick.

First, modify the cmd script so it calls Powershell rather than CScript:

@echo off
for /f "delims=" %%i in ('powershell -file getpwd.ps1') do set passwd=%%i

The Powershell script is equally simple:

$password = Read-Host "Enter password" -AsSecureString
$password = [Runtime.InteropServices.Marshal]::SecureStringToBSTR($password)
$password = [Runtime.InteropServices.Marshal]::PtrToStringAuto($password)
echo $password

although with some marshalling to get the actual password text.

Remember that, to run local unsigned Powershell scripts on your machine, you may need to modify the execution policy from the (draconian, though very safe) default, with something like:

set-executionpolicy remotesigned

from within Powershell itself.

Yeah, Date object complects date and time, so comparing it with just date value does not work.

You can simply use the $where operator to express more complex condition with Javascript boolean expression :)

db.posts.find({ '$where': 'this.created_on.toJSON().slice(0, 10) == "2012-07-14"' })

created_on is the datetime field and 2012-07-14 is the specified date.

Date should be exactly in YYYY-MM-DD format.

Note: Use $where sparingly, it has performance implications.

I personally use cron, but the Jobs Scheduling parts of django-extensions looks interesting.

Use the below format, it would work on all the browsers

var year = 2016;
var month = 02;           // month varies from 0-11 (Jan-Dec)
var day = 23;

month = month<10?"0"+month:month;        // to ensure YYYY-MM-DD format
day = day<10?"0"+day:day;

dateObj = new Date(year+"-"+month+"-"+day);

alert(dateObj); 

//Your output would look like this "Wed Mar 23 2016 00:00:00 GMT+0530 (IST)"

//Note this would be in the current timezone in this case denoted by IST, to convert to UTC timezone you can include

alert(dateObj.toUTCSting);

//Your output now would like this "Tue, 22 Mar 2016 18:30:00 GMT"

Note that now the dateObj shows the time in GMT format, also note that the date and time have been changed correspondingly.

The "toUTCSting" function retrieves the corresponding time at the Greenwich meridian. This it accomplishes by establishing the time difference between your current timezone to the Greenwich Meridian timezone.

In the above case the time before conversion was 00:00 hours and minutes on the 23rd of March in the year 2016. And after conversion from GMT+0530 (IST) hours to GMT (it basically subtracts 5.30 hours from the given timestamp in this case) the time reflects 18.30 hours on the 22nd of March in the year 2016 (exactly 5.30 hours behind the first time).

Further to convert any date object to timestamp you can use

alert(dateObj.getTime());

//output would look something similar to this "1458671400000"

This would give you the unique timestamp of the time

Okay I have got it working, hope this information is useful.

1. First of all I now realize that not only do self-extracting zip start extracting with doubleclick, but they require no extraction application to be installed on the users computer because the extractor code is in the archive itself. This means that you will get a different user experience depending on what you application you use to create the sfx

2. I went with WinRar as follows, this does not require you to create an sfx file, everything can be created via the gui:

   • Select files, right click and select Add to Archive
   • Use Browse.. to create the archive in the folder above
   • Change Archive Format to Zip
   • Enable Create SFX archive
   • Select Advanced tab
   • Select SFX Options
   • Select Setup tab
   • Enter setup.exe into the Run after Extraction field
   • Select Modes tab
   • Enable Unpack to temporary folder
   • Select text and Icon tab
   • Enter a more appropriate title for your task
   • Select OK
   • Select OK

The resultant exe unzips to a temporary folder and then starts the installer

phpMyAdmin provides a GUI for this within the structure view of a table. Check to select the column you want to move and click the change action at the bottom of the column list. You can then change all of the column properties and you'll find the 'move column' function at the far right of the screen.

Of course this is all just building the queries in the perfectly good top answer but GUI fans might appreciate the alternative.

my phpMyAdmin version is 4.1.7

Jackson's JSON Views might be a simpler way of achieving your requirements, especially if you have some flexibility in your JSON format.

If {"id":7, "itemNr":"TEST", "createdBy":{id:3}} is an acceptable representation then this will be very easy to achieve with very little code.

You would just annotate the name field of User as being part of a view, and specify a different view in your serialisation request (the un-annotated fields would be included by default)

For example: Define the views:

public class Views {
    public static class BasicView{}
    public static class CompleteUserView{}
}

Annotate the User:

public class User {
    public final int id;

    @JsonView(Views.CompleteUserView.class)
    public final String name;

    public User(int id, String name) {
        this.id = id;
        this.name = name;
    }
}

And serialise requesting a view which doesn't contain the field you want to hide (non-annotated fields are serialised by default):

objectMapper.getSerializationConfig().withView(Views.BasicView.class);

For completeness' sake, don't forget std::string::copy().

std::string str = "string";
const size_t MAX = 80;
char chrs[MAX];

str.copy(chrs, MAX);

std::string::copy() doesn't NUL terminate. If you need to ensure a NUL terminator for use in C string functions:

std::string str = "string";
const size_t MAX = 80;
char chrs[MAX];

memset(chrs, '\0', MAX);
str.copy(chrs, MAX-1);

Nothing worked for me until I encoded the video properly. Try this guide for the correct handbrake settings: http://forum.handbrake.fr/viewtopic.php?f=7&t=9694

Adding a wrapper <div> around the entirety of your content will indeed work. While semantically "icky", I added an div with a class of overflowWrap right inside the body tag and then set set my CSS like this:

html, body, .overflowWrap {
overflow-x: hidden;
}

Might be overkill now, but works like a charm!

In python 2 only (not python 3):

assert not isinstance(lst, basestring)

Is actually what you want, otherwise you'll miss out on a lot of things which act like lists, but aren't subclasses of list or tuple.

You are iterating over one string (word), but then using the index into that to look up a character in so_far. There is no guarantee that these two strings have the same length.

If using latest Git,

git merge --abort

else this will do the job in older git versions

git reset --merge

or

git reset --hard

TL;DR

You should use FLUSH PRIVILEGES; only if you modify the grant tables directly using statements such as INSERT, UPDATE, or DELETE.

If you don't have an array but you are trying to use your observable like an array even though it's a stream of objects, this won't work natively. I show how to fix this below assuming you only care about adding objects to the observable, not deleting them.

If you are trying to use an observable whose source is of type BehaviorSubject, change it to ReplaySubject then in your component subscribe to it like this:

Component

this.messages$ = this.chatService.messages$.pipe(scan((acc, val) => [...acc, val], []));

Html

<div class="message-list" *ngFor="let item of messages$ | async">

An other way which makes then your jsfiddle less buggy (needed double click on open).

This doesn't use any delegated event to body level

Set tabindex="-1" to DIV .popup ( and for style CSS outline:0 )

DEMO

$(".link").click(function(e){
    e.preventDefault();
    $(".popup").fadeIn(300,function(){$(this).focus();});
});

$('.close').click(function() {
   $(".popup").fadeOut(300);
});
$(".popup").on('blur',function(){
    $(this).fadeOut(300);
});

Use the power of Python and lean on one of the best libraries around: requests

import requests

r = requests.get('https://my.website.com/rest/path', auth=('myusername', 'mybasicpass'))
print(r.text)

Variable r (requests response) has a lot more parameters that you can use. Best thing is to pop into the interactive interpreter and play around with it, and/or read requests docs.

In case you are here looking for a fast string concatenation method in Python, then you do not need a special StringBuilder class. Simple concatenation works just as well without the performance penalty seen in C#.

resultString = ""

resultString += "Append 1"
resultString += "Append 2"

See Antoine-tran's answer for performance results

Maybe the anwswers here are obsolete... in any case, for me running Symfony 4, it is easy Just type symfony -V from the command line.

Use ssh-agent for your keys.

(Swift 3) Add text box and uipickerview to the storyboard then add delegate and data source to uipickerview and add delegate to textbox. Follow video for assistance https://youtu.be/SfjZwgxlwcc

        return 1
    }

    public func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int{

        return list.count
    }

    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {

Some people find the following alternative syntax easier to see what is going on:

select t1.value,t2.value
from MyTable t1
    inner join MyTable t2 on
        t1.id = t2.id
where t1.id = @id

For me, it was wrong login and password.

• cd /usr/local
• git status
• Discard all the changes (unless you actually want to try to commit to Homebrew - you probably don't)
• git status til it's clean
• brew update

This can be done without inspect, I guess.

Take the following class:

 class Test:
   a = 1
   b = 2

   def __init__(self):
     self.c = 42

   @staticmethod
   def toto():
     return "toto"

   def test(self):
     return "test"

Looking at the members along with their types:

t = Test()
l = [ (x, eval('type(x.%s).__name__' % x)) for x in dir(a) ]

... gives:

[('__doc__', 'NoneType'),
 ('__init__', 'instancemethod'),
 ('__module__', 'str'),
 ('a', 'int'),
 ('b', 'int'),
 ('c', 'int'),
 ('test', 'instancemethod'),
 ('toto', 'function')]

So to output only the variables, you just have to filter the results by type, and names not starting with '__'. E.g.

filter(lambda x: x[1] not in ['instancemethod', 'function'] and not x[0].startswith('__'), l)

[('a', 'int'), ('b', 'int'), ('c', 'int')] # actual result

That's it.

Note: if you're using Python 3, convert the iterators to lists.

If you want a more robust way to do it, use inspect.
