We have the following string which is a valid JSON ...
Clearly the JSON parser disagrees!
However, the exception says that the error is at "line 1: column 9", and there is no "http" token near the beginning of the JSON. So I suspect that the parser is trying to parse something different than this string when the error occurs.
You need to find what JSON is actually being parsed. Run the application within a debugger, set a breakpoint on the relevant constructor for JsonParseException ... then find out what is in the ByteArrayInputStream that it is attempting to parse.
All above answers compares well, but if you need to use custom function for mapping, and you have numpy.ndarray, and you need to retain the shape of array.
I have compare just two, but it will retain the shape of ndarray. I have used the array with 1 million entries for comparison. Here I use square function. I am presenting the general case for n dimensional array. For two dimensional just make iter for 2D.
import numpy, time
def A(e):
return e * e
def timeit():
y = numpy.arange(1000000)
now = time.time()
numpy.array([A(x) for x in y.reshape(-1)]).reshape(y.shape)
print(time.time() - now)
now = time.time()
numpy.fromiter((A(x) for x in y.reshape(-1)), y.dtype).reshape(y.shape)
print(time.time() - now)
now = time.time()
numpy.square(y)
print(time.time() - now)
Output
>>> timeit()
1.162431240081787 # list comprehension and then building numpy array
1.0775556564331055 # from numpy.fromiter
0.002948284149169922 # using inbuilt function
here you can clearly see numpy.fromiter user square function, use any of your choice. If you function is dependent on i, j that is indices of array, iterate on size of array like for ind in range(arr.size), use numpy.unravel_index to get i, j, .. based on your 1D index and shape of array numpy.unravel_index

Answering with respect to an external library -
Compile:
javac -cp ./<external lib jar>: <program-name>.java
Execute:
java -cp ./<external lib jar>: <program-name>
The above scheme works well in OS X and Linux systems. Notice the : in the classpath.
A comment to jarijira
Well I have had many issues with .html and .empty() methods for inputs o. If the id represents an input and not another type of html selector like
or use the .val() function to manipulate.
For example: this is the proper way to manipulate input values
<textarea class="form-control" id="someInput"></textarea>
$(document).ready(function () {
var newVal='test'
$('#someInput').val('') //clear input value
$('#someInput').val(newVal) //override w/ the new value
$('#someInput').val('test2)
newVal= $('#someInput').val(newVal) //get input value
}
For improper, but sometimes works For example: this is the proper way to manipulate input values
<textarea class="form-control" id="someInput"></textarea>
$(document).ready(function () {
var newVal='test'
$('#someInput').html('') //clear input value
$('#someInput').empty() //clear html inside of the id
$('#someInput').html(newVal) //override the html inside of text area w/ string could be '<div>test3</div>
really overriding with a string manipulates the value, but this is not the best practice as you do not put things besides strings or values inside of an input.
newVal= $('#someInput').val(newVal) //get input value
}
An issue that I had was I was using the $getJson method and I was indeed able to use .html calls to manipulate my inputs. However, whenever I had an error or fail on the getJSON I could no longer change my inputs using the .clear and .html calls. I could still return the .val(). After some experimentation and research I discovered that you should only use the .val() function to make changes to input fields.
UPDATE
I also tried this, but to no avail:
$(document).ready(function() {
$('body :not(.wr-dropdown)').bind("click", function(e) {
$('.test').focus();
})
$('.wr-dropdown').on('change', function(e) {
if ($(".wr-dropdow option[value='/search']")) {
setTimeout(function(e) {
$('body :not(.wr-dropdown)').trigger("click");
},3000)
}
});
});
I am confused as to why you say this isn't working because your JSFiddle is working just fine, but here is my suggestion anyway...
Try this line of code in your SetTimeOut function on your click event:
document.myInput.focus();
myInput correlates to the name attribute of the input tag.
<input name="myInput">
And use this code to blur the field:
document.activeElement.blur();
Is this any help?

From a phylosophic point of view :
An abstract class represents an "is a" relationship. Lets say I have fruits, well I would have a Fruit abstract class that shares common responsabilities and common behavior.
An interface represents a "should do" relationship. An interface, in my opinion (which is the opinion of a junior dev), should be named by an action, or something close to an action, (Sorry, can't find the word, I'm not an english native speaker) lets say IEatable. You know it can be eaten, but you don't know what you eat.
From a coding point of view :
If your objects have duplicated code, it is an indication that they have common behavior, which means you might need an abstract class to reuse the code, which you cannot do with an interface.
Another difference is that an object can implement as many interfaces as you need, but you can only have one abstract class because of the "diamond problem" (check out here to know why! http://en.wikipedia.org/wiki/Multiple_inheritance#The_diamond_problem)
I probably forget some points, but I hope it can clarify things.
PS : The "is a"/"should do" is brought by Vivek Vermani's answer, I didn't mean to steal his answer, just to reuse the terms because I liked them!
is used for formatting purpose which is used to specify the space needed between the edges of the cells and also in the cell contents. The general format of specifying cell padding is as follows:
< table width="100" border="2" cellpadding="5">
The above adds 5 pixels of padding inside each cell .
Cell spacing is one also used f formatting but there is a major difference between cell padding and cell spacing. It is as follows: Cell padding is used to set extra space which is used to separate cell walls from their contents. But in contrast cell spacing is used to set space between cells.
It works in the edu version for me. It was not necessary for me to specify a -s option in the interpreter options.
Try using qx{command} rather than backticks. To me, it's a bit better because: you can do SQL with it and not worry about escaping quotes and such. Depending on the editor and screen, my old eyes tend to miss the tiny back ticks, and it shouldn't ever have an issue with being overloaded like using angle brackets versus glob.
You are dealing with the problem of browser cache.
Disable the cache in the page itself. That will not save supporting file of page in browser/cache.
<meta http-equiv="cache-control" content="max-age=0" />
<meta http-equiv="cache-control" content="no-cache" />
<meta http-equiv="expires" content="0" />
<meta http-equiv="expires" content="Tue, 01 Jan 1990 12:00:00 GMT" />
This code you require/need to insert in head tag of the page you are debugging, or in head tag of master page of your site
This will not allow browser to cache file, eventually files will not be stored in browser temporary files, so no cache, so no reloading will be required :)
I am sure this will do :)

As kmcamara discovered, this is exactly the kind of problem that VLOOKUP is intended to solve, and using vlookup is arguably the simplest of the alternative ways to get the job done.
In addition to the three parameters for lookup_value, table_range to be searched, and the column_index for return values, VLOOKUP takes an optional fourth argument that the Excel documentation calls the "range_lookup".
Expanding on deathApril's explanation, if this argument is set to TRUE (or 1) or omitted, the table range must be sorted in ascending order of the values in the first column of the range for the function to return what would typically be understood to be the "correct" value. Under this default behavior, the function will return a value based upon an exact match, if one is found, or an approximate match if an exact match is not found.
If the match is approximate, the value that is returned by the function will be based on the next largest value that is less than the lookup_value. For example, if "12AT8003" were missing from the table in Sheet 1, the lookup formulas for that value in Sheet 2 would return '2', since "12AT8002" is the largest value in the lookup column of the table range that is less than "12AT8003". (VLOOKUP's default behavior makes perfect sense if, for example, the goal is to look up rates in a tax table.)
However, if the fourth argument is set to FALSE (or 0), VLOOKUP returns a looked-up value only if there is an exact match, and an error value of #N/A if there is not. It is now the usual practice to wrap an exact VLOOKUP in an IFERROR function in order to catch the no-match gracefully. Prior to the introduction of IFERROR, no matches were checked with an IF function using the VLOOKUP formula once to check whether there was a match, and once to return the actual match value.
Though initially harder to master, deusxmach1na's proposed solution is a variation on a powerful set of alternatives to VLOOKUP that can be used to return values for a column or list to the left of the lookup column, expanded to handle cases where an exact match on more than one criterion is needed, or modified to incorporate OR as well as AND match conditions among multiple criteria.
Repeating kcamara's chosen solution, the VLOOKUP formula for this problem would be:
=VLOOKUP(A1,Sheet1!A$1:B$600,2,FALSE)
I found the solution.
As said in the EDIT of my answer, a <div> is misfunctioning in a <table>.
So I wrote this code instead :
<tr id="hidden" style="display:none;">
<td class="depot_table_left">
<label for="sexe">Sexe</label>
</td>
<td>
<select type="text" name="sexe">
<option value="1">Sexe</option>
<option value="2">Joueur</option>
<option value="3">Joueuse</option>
</select>
</td>
</tr>
And this is working fine.
Thanks everybody ;)
A robust way to check if an object is an array in javascript is detailed here:
Here are two functions from the xa.js framework which I attach to a utils = {} ‘container’. These should help you properly detect arrays.
var utils = {};
/**
* utils.isArray
*
* Best guess if object is an array.
*/
utils.isArray = function(obj) {
// do an instanceof check first
if (obj instanceof Array) {
return true;
}
// then check for obvious falses
if (typeof obj !== 'object') {
return false;
}
if (utils.type(obj) === 'array') {
return true;
}
return false;
};
/**
* utils.type
*
* Attempt to ascertain actual object type.
*/
utils.type = function(obj) {
if (obj === null || typeof obj === 'undefined') {
return String (obj);
}
return Object.prototype.toString.call(obj)
.replace(/\[object ([a-zA-Z]+)\]/, '$1').toLowerCase();
};
If you then want to check if an object is in an array, I would also include this code:
/**
* Adding hasOwnProperty method if needed.
*/
if (typeof Object.prototype.hasOwnProperty !== 'function') {
Object.prototype.hasOwnProperty = function (prop) {
var type = utils.type(this);
type = type.charAt(0).toUpperCase() + type.substr(1);
return this[prop] !== undefined
&& this[prop] !== window[type].prototype[prop];
};
}
And finally this in_array function:
function in_array (needle, haystack, strict) {
var key;
if (strict) {
for (key in haystack) {
if (!haystack.hasOwnProperty[key]) continue;
if (haystack[key] === needle) {
return true;
}
}
} else {
for (key in haystack) {
if (!haystack.hasOwnProperty[key]) continue;
if (haystack[key] == needle) {
return true;
}
}
}
return false;
}
On Webpack 2 I tried all 12 devtool options. The following options link to the original file in the console and preserve line numbers. See the note below re: lines only.
https://webpack.js.org/configuration/devtool
devtool best dev options
build rebuild quality look
eval-source-map slow pretty fast original source worst
inline-source-map slow slow original source medium

inline-cheap-module-source-map medium pretty slow original source (lines only) best

Source Maps are simplified to a single mapping per line. This usually means a single mapping per statement (assuming you author is this way). This prevents you from debugging execution on statement level and from settings breakpoints on columns of a line. Combining with minimizing is not possible as minimizers usually only emit a single line.
REVISITING THIS
On a large project I find ... eval-source-map rebuild time is ~3.5s ... inline-source-map rebuild time is ~7s
Yes. Google Chrome has deprecated the feature in version 50. If you tried to use it in chrome the error is:
getCurrentPosition() and watchPosition() are deprecated on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS. See https://sites.google.com/a/chromium.org/dev/Home/chromium-security/deprecating-powerful-features-on-insecure-origins for more details.
So, you have to add SSL certificate. Well, that's the only way.
And it's quite easy now using Let's Encrypt. Here's guide
And for testing purpose you could try this:
1.localhost is treated as a secure origin over HTTP, so if you're able to run your server from localhost, you should be able to test the feature on that server.
2.You can run chrome with the --unsafely-treat-insecure-origin-as-secure="http://example.com" flag (replacing "example.com" with the origin you actually want to test), which will treat that origin as secure for this session. Note that you also need to include the --user-data-dir=/test/only/profile/dir to create a fresh testing profile for the flag to work.
I think Firefox also restricted user from accessing GeoLocation API requests from http. Here's the webkit changelog: https://trac.webkit.org/changeset/200686
This problem comes while you are running Test. Add dependency

handler.removeCallbacksAndMessages(null);
In the docs for removeCallbacksAndMessages it says...
Remove any pending posts of callbacks and sent messages whose obj is token. If token is
null, all callbacks and messages will be removed.

}
usage : roundOff(600.23458,2); will return 600.23
You can use INTERVAL type or just add calculated number value - "1" is equal "1 day".
first way:
select date_column + INTERVAL '0 01:00:00' DAY TO SECOND from dual;
second way:
select date_column + 1/24 from dual;
First way is more convenient when you need to add a complicated value - for example, "1 day 3 hours 25 minutes 49 seconds". See also: http://www.oracle-base.com/articles/misc/oracle-dates-timestamps-and-intervals.php
Also you have to remember that oracle have two interval types - DAY TO SECOND and YEAR TO MONTH. As for me, one interval type would be better, but I hope people in oracle knows, what they do ;)
In IE11 we can change user agent to IE10, IE9 and even as windows phone. It is really good

This convention is used for special variables or methods (so-called “magic method”) such as __init__ and __len__. These methods provides special syntactic features or do special things.
For example, __file__ indicates the location of Python file, __eq__ is executed when a == b expression is executed.
A user of course can make a custom special method, which is a very rare case, but often might modify some of the built-in special methods (e.g. you should initialize the class with __init__ that will be executed at first when an instance of a class is created).
class A:
def __init__(self, a): # use special method '__init__' for initializing
self.a = a
def __custom__(self): # custom special method. you might almost do not use it
pass

As of May 2018 you no longer need to create tsconfig.json manually or configure task runner.
tsc --init in your project folder to create tsconfig.json file (if you don't have one already).tsc: watch - tsconfig.json.You can have several tsconfig.json files in your workspace and run multiple compilations at once if you want (e.g. frontend and backend separately).
You can do this with Build commands:
Create a simple tsconfig.json with "watch": true (this will instruct compiler to watch all compiled files):
{
"compilerOptions": {
"target": "es5",
"out": "js/script.js",
"watch": true
}
}
Note that files array is omitted, by default all *.ts files in all subdirectories will be compiled. You can provide any other parameters or change target/out, just make sure that watch is set to true.
Configure your task (Ctrl+Shift+P -> Configure Task Runner):
{
"version": "0.1.0",
"command": "tsc",
"showOutput": "silent",
"isShellCommand": true,
"problemMatcher": "$tsc"
}
Now press Ctrl+Shift+B to build the project. You will see compiler output in the output window (Ctrl+Shift+U).
The compiler will compile files automatically when saved. To stop the compilation, press Ctrl+P -> > Tasks: Terminate Running Task

Error message clearly says that source parameter is null. Source is the enumerable you are enumerating. In your case it is ListMetadataKor object. And its definitely null at the time you are filtering it second time. Make sure you never assign null to this list. Just check all references to this list in your code and look for assignments.
The error message which you specified is nothing but you are not specifying goal for maven build.

Building on the Python 2 solution from @GarethLatty, the following is a way to get a single line equivalent without intermediate variables in Python 2.
t=iter([1, 1, 2, 3, 5, 8, 13, 21, 34, 55]);h,t = [(h,list(t)) for h in t][0]
If you need it to be exception-proof (i.e. supporting empty list), then add:
t=iter([]);h,t = ([(h,list(t)) for h in t]+[(None,[])])[0]
If you want to do it without the semicolon, use:
h,t = ([(h,list(t)) for t in [iter([1,2,3,4])] for h in t]+[(None,[])])[0]
When adding support for mimetype (as suggested by @ProVega) then it is also best practice to remove the type before adding it - this is to prevent unexpected errors when deploying to servers where support for the type already exists, for example:
<staticContent>
<remove fileExtension=".json" />
<mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>
You are missing the std namespace reference in the cc file. You should also call nom.c_str() because there is no implicit conversion from std::string to const char * expected by ifstream's constructor.
Polygone::Polygone(std::string nom) {
std::ifstream fichier (nom.c_str(), std::ifstream::in);
// ...
}
The purpose of using this is to implement an additional layer of security between the user interface and the database. By using this layer, data can be normalized before being inserted into your data structure. (Capitals are Capitals, no leading or trailing spaces, all dates at properly formed.)
But there are a few nuances to this which you might not be aware of.
First of all, up until now, you've probably written all your queries in something similar to the URL, and you pass the parameters using the URL itself. Using the PDO, all of this is done under the user interface level. User interface hands off the ball to the PDO which carries it down field and plants it into the database for a 7-point TOUCHDOWN.. he gets seven points, because he got it there and did so much more securely than passing information through the URL.
You can also harden your site to SQL injection by using a data-layer. By using this intermediary layer that is the ONLY 'player' who talks to the database itself, I'm sure you can see how this could be much more secure. Interface to datalayer to database, datalayer to database to datalayer to interface.
And:
By implementing best practices while writing your code you will be much happier with the outcome.

If you have Windows Subsystem for Linux (WSL), natively on Windows 10 and Windows Server 2019 you can do it like this:
Set up WSL:
To enable Windows Subsystem for Linux, follow the instructions on Microsoft Docs. The short version is: In Windows 10, Microsoft replaces Command Prompt with PowerShell as the default shell. Open PowerShell as Administrator and run this command to enable Windows Subsystem for Linux (WSL):
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
Reboot Windows after making the change—note that you only need to do this one time.
Download and install one of the supported Linux distros from the Microsoft Store. Ubuntu works fine.
Note that Ubuntu 20.04 LTS may give you some trouble because of a known issue with the realtime clock (as of August 2020). Choosing Ubuntu 18.04 LTS instead avoids that issue.
Install and Test Redis:
Launch the installed distro from your Windows Store and then install redis-server. The following example works with Ubuntu (you’ll need to wait for initialization and create a login upon first use):
> sudo apt-get update
> sudo apt-get upgrade
> sudo apt-get install redis-server
> redis-cli -v
Restart the Redis server to make sure it is running:
> sudo service redis-server restart
Execute a simple Redis command to verify your Redis server is running and available:
$ redis-cli
127.0.0.1:6379> set user:1 "Oscar"
127.0.0.1:6379> get user:1
"Oscar"
To stop your Redis server:
> sudo service redis-server stop

When you have two docker images "already" created and you want to put two containers to communicate with one-another.
For that, you can conveniently run each container with its own --name and use the --link flag to enable communication between them. You do not get this during docker build though.
When you are in a scenario like myself, and it is your
docker build -t "centos7/someApp" someApp/
That breaks when you try to
curl http://172.17.0.1:localPort/fileIWouldLikeToDownload.tar.gz > dump.tar.gz
and you get stuck on "curl/wget" returning no "route to host".
The reason is security that is set in place by docker that by default is banning communication from a container towards the host or other containers running on your host. This was quite surprising to me, I must say, you would expect the echosystem of docker machines running on a local machine just flawlessly can access each other without too much hurdle.
The explanation for this is described in detail in the following documentation.
http://www.dedoimedo.com/computers/docker-networking.html
Two quick workarounds are given that help you get moving by lowering down the network security.
The simplest alternative is just to turn the firewall off - or allow all. This means running the necessary command, which could be systemctl stop firewalld, iptables -F or equivalent.

Coming across this question,
no answer brought up the possibility of using .setAttribute() in addition to .value()
document.getElementById('some-input').value="1337";
document.getElementById('some-input').setAttribute("value", "1337");
Though unlikely helpful for the original questioner,
this addendum actually changes the content of the value in the pages source,
which in turn makes the value update form.reset()-proof.
I hope this may help others.

anon and chepner's answers are on the right track. Python 3.x has a print function and this is what you will need if you want to embed print within a function (and, a fortiori, lambdas).
However, you can get the print function very easily in python 2.x by importing from the standard library's future module. Check it out:
>>>from __future__ import print_function
>>>
>>>iterable = ["a","b","c"]
>>>map(print, iterable)
a
b
c
[None, None, None]
>>>
I guess that looks kind of weird, so feel free to assign the return to _ if you would like to suppress [None, None, None]'s output (you are interested in the side-effects only, I assume):
>>>_ = map(print, iterable)
a
b
c
>>>
You should use the ISO-8601 format for string representations of dates - anything else is dependent on the SQL Server language and dateformat settings.
The ISO-8601 format for a DATETIME when using only the date is: YYYYMMDD (no dashes or antyhing!)
For a DATETIME with the time portion, it's YYYY-MM-DDTHH:MM:SS (with dashes, and a T in the middle to separate date and time portions).
If you want to convert a string to a DATE for SQL Server 2008 or newer, you can use YYYY-MM-DD (with the dashes) to achieve the same result. And don't ask me why this is so inconsistent and confusing - it just is, and you'll have to work with that for now.
So in your case, you should try:
declare @a datetime
declare @b datetime
set @a = '2012-04-06T12:23:45' -- 6th of April, 2012
set @b = '2012-08-06T21:10:12' -- 6th of August, 2012
exec LogProcedure 'AccountLog', N'test', @a, @b
Furthermore - your stored proc has problem, since you're concatenating together datetime and string into a string, but you're not converting the datetime to string first, and also, you're forgetting the close quotes in your statement after both dates.
So change this line here to this:
IF @DateFirst <> '' and @DateLast <> ''
SET @FinalSQL = @FinalSQL + ' OR CONVERT(Date, DateLog) >= ''' +
CONVERT(VARCHAR(50), @DateFirst, 126) + -- convert @DateFirst to string for concatenation!
''' AND CONVERT(Date, DateLog) <=''' + -- you need closing quotes after @DateFirst!
CONVERT(VARCHAR(50), @DateLast, 126) + '''' -- convert @DateLast to string and also: closing tags after that missing!
With these settings, and once you've fixed your stored procedure which contains problems right now, it will work.
You will need to run the following code after your intent is fired to remove the notification.
NotificationManagerCompat.from(this).cancel(null, notificationId);
NB: notificationId is the same id passed to run your notification

^\p{L}{2,}$
^ asserts position at start of a line.
\p{L} matches any kind of letter from any language
{2,} Quantifier — Matches between 2 and unlimited times, as many times as possible, giving back as needed (greedy)
$ asserts position at the end of a line
So it should be a name in any language containing at least 2 letters(or symbols) without numbers or other characters.
According to the docs, #Rails.env wraps RAILS_ENV:
# File vendor/rails/railties/lib/initializer.rb, line 55
def env
@_env ||= ActiveSupport::StringInquirer.new(RAILS_ENV)
end
But, look at specifically how it's wrapped, using ActiveSupport::StringInquirer:
Wrapping a string in this class gives you a prettier way to test for equality. The value returned by Rails.env is wrapped in a StringInquirer object so instead of calling this:
Rails.env == "production"you can call this:
Rails.env.production?
So they aren't exactly equivalent, but they're fairly close. I haven't used Rails much yet, but I'd say #Rails.env is certainly the more visually attractive option due to using StringInquirer.

git checkout has the --ours option to check out the version of the file that you had locally (as opposed to --theirs, which is the version that you pulled in). You can pass . to git checkout to tell it to check out everything in the tree. Then you need to mark the conflicts as resolved, which you can do with git add, and commit your work once done:
git checkout --ours . # checkout our local version of all files
git add -u # mark all conflicted files as merged
git commit # commit the merge
Note the . in the git checkout command. That's very important, and easy to miss. git checkout has two modes; one in which it switches branches, and one in which it checks files out of the index into the working copy (sometimes pulling them into the index from another revision first). The way it distinguishes is by whether you've passed a filename in; if you haven't passed in a filename, it tries switching branches (though if you don't pass in a branch either, it will just try checking out the current branch again), but it refuses to do so if there are modified files that that would effect. So, if you want a behavior that will overwrite existing files, you need to pass in . or a filename in order to get the second behavior from git checkout.
It's also a good habit to have, when passing in a filename, to offset it with --, such as git checkout --ours -- <filename>. If you don't do this, and the filename happens to match the name of a branch or tag, Git will think that you want to check that revision out, instead of checking that filename out, and so use the first form of the checkout command.
I'll expand a bit on how conflicts and merging work in Git. When you merge in someone else's code (which also happens during a pull; a pull is essentially a fetch followed by a merge), there are few possible situations.
The simplest is that you're on the same revision. In this case, you're "already up to date", and nothing happens.
Another possibility is that their revision is simply a descendent of yours, in which case you will by default have a "fast-forward merge", in which your HEAD is just updated to their commit, with no merging happening (this can be disabled if you really want to record a merge, using --no-ff).
Then you get into the situations in which you actually need to merge two revisions. In this case, there are two possible outcomes. One is that the merge happens cleanly; all of the changes are in different files, or are in the same files but far enough apart that both sets of changes can be applied without problems. By default, when a clean merge happens, it is automatically committed, though you can disable this with --no-commit if you need to edit it beforehand (for instance, if you rename function foo to bar, and someone else adds new code that calls foo, it will merge cleanly, but produce a broken tree, so you may want to clean that up as part of the merge commit in order to avoid having any broken commits).
The final possibility is that there's a real merge, and there are conflicts. In this case, Git will do as much of the merge as it can, and produce files with conflict markers (<<<<<<<, =======, and >>>>>>>) in your working copy. In the index (also known as the "staging area"; the place where files are stored by git add before committing them), you will have 3 versions of each file with conflicts; there is the original version of the file from the ancestor of the two branches you are merging, the version from HEAD (your side of the merge), and the version from the remote branch.
In order to resolve the conflict, you can either edit the file that is in your working copy, removing the conflict markers and fixing the code up so that it works. Or, you can check out the version from one or the other sides of the merge, using git checkout --ours or git checkout --theirs. Once you have put the file into the state you want it, you indicate that you are done merging the file and it is ready to commit using git add, and then you can commit the merge with git commit.
You should use Handler's postDelayed function for this purpose. It will run your code with specified delay on the main UI thread, so you will be able to update UI controls.
private int mInterval = 5000; // 5 seconds by default, can be changed later
private Handler mHandler;
@Override
protected void onCreate(Bundle bundle) {
// your code here
mHandler = new Handler();
startRepeatingTask();
}
@Override
public void onDestroy() {
super.onDestroy();
stopRepeatingTask();
}
Runnable mStatusChecker = new Runnable() {
@Override
public void run() {
try {
updateStatus(); //this function can change value of mInterval.
} finally {
// 100% guarantee that this always happens, even if
// your update method throws an exception
mHandler.postDelayed(mStatusChecker, mInterval);
}
}
};
void startRepeatingTask() {
mStatusChecker.run();
}
void stopRepeatingTask() {
mHandler.removeCallbacks(mStatusChecker);
}
This is the only comprehensive and reliable way I've found to do this.
Assume you want to merge "tag_1.0" into "mybranch".
$git checkout tag_1.0 (will create a headless branch)
$git branch -D tagbranch (make sure this branch doesn't already exist locally)
$git checkout -b tagbranch
$git merge -s ours mybranch
$git commit -am "updated mybranch with tag_1.0"
$git checkout mybranch
$git merge tagbranch
Getting an image into Jupyter NB is a much simpler operation than most people have alluded to here.
1) Simply create an empty Markdown cell. 2) Then drag-and-drop the image file into the empty Markdown cell.
The Markdown code that will insert the image then appears.
For example, a string shown highlighted in gray below will appear in the Jupyter cell:
3) Then execute the Markdown cell by hitting Shift-Enter. The Jupyter server will then insert the image, and the image will then appear.
I am running Jupyter notebook server is: 5.7.4 with Python 3.7.0 on Windows 7.

parser.add_argument('--example', default=1)
args = parser.parse_args()
print(args.example)
test.py --example
% 1
test.py --example 2
% 2

This is a known bug in PHP v 5.2 for Windows, it is present at least to version 5.2.3: https://bugs.php.net/bug.php?id=41615
None of the suggested fixes have helped for us, we're going to have to update PHP.
=== and !== are strict comparison operators:
JavaScript has both strict and type-converting equality comparison. For
strictequality the objects being compared must have the same type and:
- Two strings are strictly equal when they have the same sequence of characters, same length, and same characters in corresponding positions.
- Two numbers are strictly equal when they are numerically equal (have the same number value).
NaNis not equal to anything, includingNaN. Positive and negative zeros are equal to one another.- Two Boolean operands are strictly equal if both are true or both are false.
- Two objects are strictly equal if they refer to the same
Object.NullandUndefinedtypes are==(but not===). [I.e. (Null==Undefined) istruebut (Null===Undefined) isfalse]
Check the type property. Would that suffice?
I'm using Conda on Windows and this answer did not work for me. But I can suggest another solution:
rename enviroment folder (old_name to new_name)
open shell and activate env with custom folder:
conda.bat activate "C:\Users\USER_NAME\Miniconda3\envs\new_name"
now you can use this enviroment, but it's not on the enviroment list. Update\install\remove any package to fix it. For example, update numpy:
conda update numpy
after applying any action to package, the environment will show in env list. To check this, type:
conda env list

You should use static_cast<char>(i) to cast the integer i to char.
reinterpret_cast should almost never be used, unless you want to cast one type into a fundamentally different type.
Also reinterpret_cast is machine dependent so safely using it requires complete understanding of the types as well as how the compiler implements the cast.
For more information about C++ casting see:

The only way I am able to make it work is by:
docker run -it -e USER=$USER -v /etc/passwd:/etc/passwd -v `pwd`:/siem mono bash

Take advantage of as.matrix:
# keep the first column
names <- df.aree[,1]
# Transpose everything other than the first column
df.aree.T <- as.data.frame(as.matrix(t(df.aree[,-1])))
# Assign first column as the column names of the transposed dataframe
colnames(df.aree.T) <- names
Just
$("#your_item").trigger("click");
using .trigger() you can simulate many type of events, just passing it as the parameter.

Typically sites that do this by loading content via ajax and listening to the readystatechanged event to update the DOM with a loading GIF or the content.
How are you currently loading your content?
The code would be similar to this:
function load(url) {

document.getElementById('loadingImg').visible = true;
// request your data...
var req = new XMLHttpRequest();
req.open("POST", url, true);
req.onreadystatechange = function () {
if (req.readyState == 4 && req.status == 200) {
// content is loaded...hide the gif and display the content...
if (req.responseText) {
document.getElementById('content').innerHTML = req.responseText;
document.getElementById('loadingImg').visible = false;
}
}
};
request.send(vars);
}

If you want to share a locally created repository, or you want to take contributions from someone elses repository - if you want to interact in any way with a new repository, it's generally easiest to add it as a remote. You do that by running git remote add [alias] [url]. That adds [url] under a local remote named [alias].
#example
$ git remote
$ git remote add github [email protected]:schacon/hw.git
$ git remote -v
I think you mean to put the rolling of the random a,b,c, etc within the loop:
a = None # initialise
while not (a in winning_numbers):
# keep rolling an a until you get one not in winning_numbers
a = random.randint(1,30)
winning_numbers.append(a)
Otherwise, a will be generated just once, and if it is in winning_numbers already, it won't be added. Since the generation of a is outside the while (in your code), if a is already in winning_numbers then too bad, it won't be re-rolled, and you'll have one less winning number.
That could be what causes your error in if guess[i] == winning_numbers[i]. (Your winning_numbers isn't always of length 5).
We can also define it using global in setupTests
// setupTests.js
global.open = jest.fn()
And call it using global in the actual test:
// yourtest.test.js
it('correct url is called', () => {
statementService.openStatementsReport(111);
expect(global.open).toBeCalled();
});
Try something like this:
public class test
{
public static void main(String a[])
{
long tmp = 1346524199000;
Date d = new Date(tmp);
System.out.println(d);

Using the standard CustomCreationConverter, I was struggling to work how to generate the correct type (Person or Employee), because in order to determine this you need to analyse the JSON and there is no built in way to do this using the Create method.
I found a discussion thread pertaining to type conversion and it turned out to provide the answer. Here is a link: Type converting.
What's required is to subclass JsonConverter, overriding the ReadJson method and creating a new abstract Create method which accepts a JObject.
The JObject class provides a means to load a JSON object and provides access to the data within this object.
The overridden ReadJson method creates a JObject and invokes the Create method (implemented by our derived converter class), passing in the JObject instance.
This JObject instance can then be analysed to determine the correct type by checking existence of certain fields.
Example
string json = "[{
\"Department\": \"Department1\",
\"JobTitle\": \"JobTitle1\",
\"FirstName\": \"FirstName1\",
\"LastName\": \"LastName1\"
},{
\"Department\": \"Department2\",
\"JobTitle\": \"JobTitle2\",
\"FirstName\": \"FirstName2\",
\"LastName\": \"LastName2\"
},
{\"Skill\": \"Painter\",
\"FirstName\": \"FirstName3\",
\"LastName\": \"LastName3\"
}]";
List<Person> persons =
JsonConvert.DeserializeObject<List<Person>>(json, new PersonConverter());
...
public class PersonConverter : JsonCreationConverter<Person>
{
protected override Person Create(Type objectType, JObject jObject)
{
if (FieldExists("Skill", jObject))
{
return new Artist();
}
else if (FieldExists("Department", jObject))
{
return new Employee();
}
else
{
return new Person();
}
}
private bool FieldExists(string fieldName, JObject jObject)
{
return jObject[fieldName] != null;
}
}
public abstract class JsonCreationConverter<T> : JsonConverter
{
/// <summary>
/// Create an instance of objectType, based properties in the JSON object
/// </summary>
/// <param name="objectType">type of object expected</param>
/// <param name="jObject">
/// contents of JSON object that will be deserialized
/// </param>
/// <returns></returns>
protected abstract T Create(Type objectType, JObject jObject);
public override bool CanConvert(Type objectType)
{
return typeof(T).IsAssignableFrom(objectType);
}
public override bool CanWrite
{
get { return false; }
}
public override object ReadJson(JsonReader reader,
Type objectType,
object existingValue,
JsonSerializer serializer)
{
// Load JObject from stream
JObject jObject = JObject.Load(reader);
// Create target object based on JObject
T target = Create(objectType, jObject);
// Populate the object properties
serializer.Populate(jObject.CreateReader(), target);
return target;
}
}
If you call it the way you had it...
$('.leadtoscore').click(add_event('shot'));
...you would need to have add_event() return a function, like...
function add_event(param) {
return function() {
// your code that does something with param
alert( param );
};
}

When you set keys (primary or foreign) you are setting constraints on how they can be used, which in turn limits what you can do with them. If you really want to alter the column, you could re-create the table without the constraints, although I'd recommend against it. Generally speaking, if you have a situation in which you want to do something, but it is blocked by a constraint, it's best resolved by changing what you want to do rather than the constraint.

I use Git Bash for my Windows.
$ eval $(ssh-agent -s) //activates the connection
$ ssh-add ~/.ssh/id_rsa //adds the identity
$ clip < ~/.ssh/id_rsa.pub //THIS IS THE IMPORTANT ONE. This adds your key to your clipboard. Go back to GitHub and just paste it in, and voilá! You should be good to go.
Shouldn't you have:
DELETE FROM tableA WHERE entitynum IN (...your select...)
Now you just have a WHERE with no comparison:
DELETE FROM tableA WHERE (...your select...)
So your final query would look like this;
DELETE FROM tableA WHERE entitynum IN (
SELECT tableA.entitynum FROM tableA q
INNER JOIN tableB u on (u.qlabel = q.entityrole AND u.fieldnum = q.fieldnum)
WHERE (LENGTH(q.memotext) NOT IN (8,9,10) OR q.memotext NOT LIKE '%/%/%')
AND (u.FldFormat = 'Date')
)

n = rand()

n/RAND_MAX = x/l
Refactor:

Gives:
x = l*n/RAND_MAX

Symptom:
channel 2: open failed: connect failed: Connection refused
debug1: channel 2: free: direct-tcpip:
listening port 8890 for 169.254.76.1 port 8890,
connect from ::1 port 52337 to ::1 port 8890, nchannels 8
My scenario; i had to use the remote server as a bastion host to connect elsewhere. Final Destination/Target: 169.254.76.1, port 8890. Through intermediary server with public ip: ec2-54-162-180-7.compute-1.amazonaws.com
SSH local port forwarding command:
ssh -i ~/keys/dev.tst -vnNT -L :8890:169.254.76.1:8890
[email protected]
What the problem was: There was no service bound on port 8890 in the target host. i had forgotten to start the service.
How did i trouble shoot:
SSH into bastion host and then do curl.
Hope this helps.
You can use StringBuilder:
StringBuilder sb = new StringBuilder();
sb.append('a');
sb.append('b');
sb.append('c');
String str = sb.toString()
Or if you already have the characters, you can pass a character array to the String constructor:
String str = new String(new char[]{'a', 'b', 'c'});
The traceback module provides methods for formatting and printing exceptions and their tracebacks, e.g. this would print exception like the default handler does:
import traceback
try:
1/0
except Exception:
traceback.print_exc()
Output:
Traceback (most recent call last):
File "C:\scripts\divide_by_zero.py", line 4, in <module>
1/0
ZeroDivisionError: division by zero
use this function to get a standard array back of the type you are after...

As described in the Apple Worldwide Developer Relations Intermediate Certificate Expiration:
The previous Apple Worldwide Developer Relations Certification Intermediate Certificate expired on February 14, 2016 and the renewed certificate must now be used when signing Apple Wallet Passes, push packages for Safari Push Notifications, Safari Extensions, and submissions to the App Store, Mac App Store, and App Store for Apple TV.
All developers should download and install the renewed certificate on their development systems and servers. All apps will remain available on the App Store for iOS, Mac, and Apple TV.
The new valid certificate will look like the following:
It will display (this certificate is valid) with a green mark.
So, go to your Key Chain Access. Just delete the old certificate and replace it with the new one (renewed certificate) as Apple described in the document. Mainly the problem is only with the Apple push notification service and extensions as described in the Apple document.
You can also check the listing of certificates in https://www.apple.com/certificateauthority/
Certificate Revocation List:
Now this updated certificate will expire on 2023-02-08.
If you could not see the old certificate then go to the System Keychains and from edit menu and select the option Show Expired Certificates.
Now you can see the following certificate that you have to delete:
You can use operator.itemgetter:
from operator import itemgetter
a = [-2, 1, 5, 3, 8, 5, 6]
b = [1, 2, 5]
print(itemgetter(*b)(a))
# Result:
(1, 5, 5)
Or you can use numpy:
import numpy as np
a = np.array([-2, 1, 5, 3, 8, 5, 6])
b = [1, 2, 5]
print(list(a[b]))
# Result:
[1, 5, 5]
But really, your current solution is fine. It's probably the neatest out of all of them.
Another option is to download and install a new version using an installer.
Custom serialization and deserialization.
"from_json" (class method) builds a Model object based on json data.
"deserialize" could be called only on instance, and merge all data from json into Model instance.
"serialize" - recursive serialization
__write_only__ property is needed to define write only properties ("password_hash" for example).
class Serializable(object):
__exclude__ = ('id',)
__include__ = ()
__write_only__ = ()
@classmethod
def from_json(cls, json, selfObj=None):
if selfObj is None:
self = cls()
else:
self = selfObj
exclude = (cls.__exclude__ or ()) + Serializable.__exclude__
include = cls.__include__ or ()
if json:
for prop, value in json.iteritems():
# ignore all non user data, e.g. only
if (not (prop in exclude) | (prop in include)) and isinstance(
getattr(cls, prop, None), QueryableAttribute):

It is so simple, you have 2 objects with the same name and when you say: bank_holiday[month] python thinks you wanna run your function and got ERROR.
Just rename your array to bank_holidays <--- add a 's' at the end! like this:
bank_holidays= [1, 0, 1, 1, 2, 0, 0, 1, 0, 0, 0, 2] #gives the list of bank holidays in each month
def bank_holiday(month):
if month <1 or month > 12:
print("Error: Out of range")
return
print(bank_holidays[month-1],"holiday(s) in this month ")
bank_holiday(int(input("Which month would you like to check out: ")))

This happens when you have previously changed your icon or the ic_launcher; and when that ic_launcher no longer exists in your base folder.
Try adding a png image and giving the same name and then copy it to your drawable folder.Now re build the project.
Firefox does not support the MPEG H.264 (mp4) format at this time, due to a philosophical disagreement with the closed-source nature of the format.
To play videos in all browsers without using plugins, you will need to host multiple copies of each video, in different formats. You will also need to use an alternate form of the video tag, as seen in the JSFiddle from @TimHayes above, reproduced below. Mozilla claims that only mp4 and WebM are necessary to ensure complete coverage of all major browsers, but you may wish to consult the Video Formats and Browser Support heading on W3C's HTML5 Video page to see which browser supports what formats.
Additionally, it's worth checking out the HTML5 Video page on Wikipedia for a basic comparison of the major file formats.
Below is the appropriate video tag (you will need to re-encode your video in WebM or OGG formats as well as your existing mp4):
<video id="video" controls='controls'>
<source src="videos/clip.mp4" type="video/mp4"/>
<source src="videos/clip.webm" type="video/webm"/>
<source src="videos/clip.ogv" type="video/ogg"/>
Your browser doesn't seem to support the video tag.

Updated Nov. 8, 2013
Network infrastructure giant Cisco has announced plans to open-source an implementation of the H.264 codec, removing the licensing fees that have so far proved a barrier to use by Mozilla. Without getting too deep into the politics of it (see following link for that) this will allow Firefox to support H.264 starting in "early 2014". However, as noted in that link, this still comes with a caveat. The H.264 codec is merely for video, and in the MPEG-4 container it is most commonly paired with the closed-source AAC audio codec. Because of this, playback of H.264 video will work, but audio will depend on whether the end-user has the AAC codec already present on their machine.
The long and short of this is that progress is being made, but you still can't avoid using multiple encodings without using a plugin.
Update: Corrected map rendering algorithm, added more illustrations, changed formating.
Perhaps the advantage for the "zig-zag" technique for mapping the tiles to the screen can be said that the tile's x and y coordinates are on the vertical and horizontal axes.
"Drawing in a diamond" approach:
By drawing an isometric map using "drawing in a diamond", which I believe refers to just rendering the map by using a nested for-loop over the two-dimensional array, such as this example:
tile_map[][] = [[...],...]
for (cellY = 0; cellY < tile_map.size; cellY++):
for (cellX = 0; cellX < tile_map[cellY].size cellX++):
draw(
tile_map[cellX][cellY],
screenX = (cellX * tile_width / 2) + (cellY * tile_width / 2)
screenY = (cellY * tile_height / 2) - (cellX * tile_height / 2)
)
Advantage:
The advantage to the approach is that it is a simple nested for-loop with fairly straight forward logic that works consistently throughout all tiles.
Disadvantage:
One downside to that approach is that the x and y coordinates of the tiles on the map will increase in diagonal lines, which might make it more difficult to visually map the location on the screen to the map represented as an array:
However, there is going to be a pitfall to implementing the above example code -- the rendering order will cause tiles that are supposed to be behind certain tiles to be drawn on top of the tiles in front:
In order to amend this problem, the inner for-loop's order must be reversed -- starting from the highest value, and rendering toward the lower value:
tile_map[][] = [[...],...]
for (i = 0; i < tile_map.size; i++):
for (j = tile_map[i].size; j >= 0; j--): // Changed loop condition here.
draw(
tile_map[i][j],
x = (j * tile_width / 2) + (i * tile_width / 2)
y = (i * tile_height / 2) - (j * tile_height / 2)
)
With the above fix, the rendering of the map should be corrected:
"Zig-zag" approach:
Advantage:
Perhaps the advantage of the "zig-zag" approach is that the rendered map may appear to be a little more vertically compact than the "diamond" approach:
Disadvantage:
From trying to implement the zig-zag technique, the disadvantage may be that it is a little bit harder to write the rendering code because it cannot be written as simple as a nested for-loop over each element in an array:
tile_map[][] = [[...],...]
for (i = 0; i < tile_map.size; i++):
if i is odd:
offset_x = tile_width / 2
else:
offset_x = 0
for (j = 0; j < tile_map[i].size; j++):
draw(
tile_map[i][j],
x = (j * tile_width) + offset_x,
y = i * tile_height / 2
)
Also, it may be a little bit difficult to try to figure out the coordinate of a tile due to the staggered nature of the rendering order:
Note: The illustrations included in this answer were created with a Java implementation of the tile rendering code presented, with the following int array as the map:
tileMap = new int[][] {
{0, 1, 2, 3},
{3, 2, 1, 0},
{0, 0, 1, 1},
{2, 2, 3, 3}
};
The tile images are:
tileImage[0] -> A box with a box inside.tileImage[1] -> A black box.tileImage[2] -> A white box.tileImage[3] -> A box with a tall gray object in it.A Note on Tile Widths and Heights
The variables tile_width and tile_height which are used in the above code examples refer to the width and height of the ground tile in the image representing the tile:
Using the dimensions of the image will work, as long as the image dimensions and the tile dimensions match. Otherwise, the tile map could be rendered with gaps between the tiles.
You can do this pretty easily using Docker, so no extra libs required. Just run this command:
docker run --rm -it -v "$GOPATH":/go -w /go/src/github.com/iron-io/ironcli golang:1.4.2-cross sh -c '
for GOOS in darwin linux windows; do
for GOARCH in 386 amd64; do
echo "Building $GOOS-$GOARCH"
export GOOS=$GOOS
export GOARCH=$GOARCH
go build -o bin/ironcli-$GOOS-$GOARCH
done
done
'

If the user doesn't exist, getent will return an error.
Here's a small shell function that doesn't ignore the exit code of getent:
get_home() {
local result; result="$(getent passwd "$1")" || return
echo $result | cut -d : -f 6
}
Here's a usage example:
da_home="$(get_home missing_user)" || {
echo 'User does NOT exist!'; exit 1
}
# Now do something with $da_home
echo "Home directory is: '$da_home'"
This add-in claims to have the functionality that I believe you seek:
Apart from an understanding of the accesses amongst modules and their respective packages. I believe the crux of it lies in the Module System#Relaxed-strong-encapsulation and I would just cherry-pick the relevant parts of it to try and answer the question.
What defines an illegal reflective access and what circumstances trigger the warning?
To aid in the migration to Java-9, the strong encapsulation of the modules could be relaxed.
An implementation may provide static access, i.e. by compiled bytecode.
May provide a means to invoke its run-time system with one or more packages of one or more of its modules open to code in all unnamed modules, i.e. to code on the classpath. If the run-time system is invoked in this way, and if by doing so some invocations of the reflection APIs succeed where otherwise they would have failed.
In such cases, you've actually ended up making a reflective access which is "illegal" since in a pure modular world you were not meant to do such accesses.
How it all hangs together and what triggers the warning in what scenario?
This relaxation of the encapsulation is controlled at runtime by a new launcher option --illegal-access which by default in Java9 equals permit. The permit mode ensures
The first reflective-access operation to any such package causes a warning to be issued, but no warnings are issued after that point. This single warning describes how to enable further warnings. This warning cannot be suppressed.
The modes are configurable with values debug(message as well as stacktrace for every such access), warn(message for each such access), and deny(disables such operations).
Few things to debug and fix on applications would be:-
--illegal-access=deny to get to know about and avoid opening packages from one module to another without a module declaration including such a directive(opens) or explicit use of --add-opens VM arg.jdeps tool with the --jdk-internals optionThe warning message issued when an illegal reflective-access operation is detected has the following form:
WARNING: Illegal reflective access by $PERPETRATOR to $VICTIM
where:
$PERPETRATORis the fully-qualified name of the type containing the code that invoked the reflective operation in question plus the code source (i.e., JAR-file path), if available, and
$VICTIMis a string that describes the member being accessed, including the fully-qualified name of the enclosing type
Questions for such a sample warning: = JDK9: An illegal reflective access operation has occurred. org.python.core.PySystemState
Last and an important note, while trying to ensure that you do not face such warnings and are future safe, all you need to do is ensure your modules are not making those illegal reflective accesses. :)
This can be done by using a pointer, and allocating memory on the heap using malloc.
Note that there is no way to later ask how big that memory block is. You have to keep track of the array size yourself.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(int argc, char** argv)
{
/* declare a pointer do an integer */
int *data;
/* we also have to keep track of how big our array is - I use 50 as an example*/
const int datacount = 50;
data = malloc(sizeof(int) * datacount); /* allocate memory for 50 int's */
if (!data) { /* If data == 0 after the call to malloc, allocation failed for some reason */
perror("Error allocating memory");
abort();
}
/* at this point, we know that data points to a valid block of memory.
Remember, however, that this memory is not initialized in any way -- it contains garbage.
Let's start by clearing it. */
memset(data, 0, sizeof(int)*datacount);
/* now our array contains all zeroes. */
data[0] = 1;
data[2] = 15;
data[49] = 66; /* the last element in our array, since we start counting from 0 */
/* Loop through the array, printing out the values (mostly zeroes, but even so) */
for(int i = 0; i < datacount; ++i) {
printf("Element %d: %d\n", i, data[i]);
}
}
That's it. What follows is a more involved explanation of why this works :)
I don't know how well you know C pointers, but array access in C (like array[2]) is actually a shorthand for accessing memory via a pointer. To access the memory pointed to by data, you write *data. This is known as dereferencing the pointer. Since data is of type int *, then *data is of type int. Now to an important piece of information: (data + 2) means "add the byte size of 2 ints to the adress pointed to by data".
An array in C is just a sequence of values in adjacent memory. array[1] is just next to array[0]. So when we allocate a big block of memory and want to use it as an array, we need an easy way of getting the direct adress to every element inside. Luckily, C lets us use the array notation on pointers as well. data[0] means the same thing as *(data+0), namely "access the memory pointed to by data". data[2] means *(data+2), and accesses the third int in the memory block.
Based on the comments left above I ran this under sqlplus instead of SQL Developer and the UPDATE statement ran perfectly, leaving me to believe this is an issue in SQL Developer particularly as there was no ORA error number being returned. Thank you for leading me in the right direction.
This technique solved my problem:
In parent form:
frmEmployee frm = new frmEmployee();
frm.MdiParent = this;
frm.Dock = DockStyle.Fill;
frm.Show();
In the child form (Load event):
this.WindowState = FormWindowState.Maximized;
Try this
<include
android:id="@+id/OnlineOffline"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
layout="@layout/YourLayoutName" />
In order to provide a clear and complete answer, I'm going to start from the very beginning before coming up with three possible solutions.
All languages that run on top of the CLR (Common Language Runtime), such as C#, F#, and Visual Basic, work under a VM that runs higher level code than machine code, which native languages like C and C++ are compiled to. It follows that methods aren't Assembly subroutines, nor are they values, unlike JavaScript as well as most functional languages; rather, they're definitions that CLR recognizes. Thus, you cannot think to pass a method as a parameter, because methods don't produce any values themselves, as they're not expressions but statements, which are stored in the generated assemblies. At this point, you'll face delegates.
A delegate represents a handle to a method (the term handle is to be preferred over pointer as it is implementation–dependent.) As I said above, a method is not a value, hence there's a special class in CLR languages, namely Delegate, which wraps up any method.
Look at the following example:
static void MyMethod()
{
Console.WriteLine("I was called by the Delegate special class!");
}
static void CallAnyMethod(Delegate yourMethod)
{
yourMethod.DynamicInvoke(new object[] { /*Array of arguments to pass*/ });
}
static void Main()
{
CallAnyMethod(MyMethod);
}
The type–unsafe way
Using the Delegate special class directly the same way as the example above. The drawback here is your code being type–unsafe, allowing arguments to be passed dynamically, with no constraints.
The custom way
Besides the Delegate special class, the concept of delegates spreads to custom delegates, which are declarations of methods preceded by the delegate keyword. They are type–checked the same as method declarations, leading to flawlessly safe code.
Here's an example:
delegate void PrintDelegate(string prompt);
static void PrintSomewhere(PrintDelegate print, string prompt)

The standard library's way
Alternatively, you can use a delegate that's part of the .NET Standard:
Action wraps up a parameterless void method.Action<T1> wraps up a void method with one parameter of type T1.Action<T1, T2> wraps up a void method with two parameters of types T1 and T2, respectively.Func<TR> wraps up a parameterless function with TR return type.Func<T1, TR> wraps up a function with TR return type and with one parameter of type T1.Func<T1, T2, TR> wraps up a function with TR return type and with two parameters of types T1 and T2, respectively.However, bear in mind that using predefined delegates like these, parameter names won't describe what they have to be passed in, nor is the delegate name meaningful on what it's supposed to do. Therefore, be cautious about when to use these delegates and refrain from using them in contexts where their purpose is not absolutely self–evident.
The latter solution is the one most people posted. I'm still mentioning it in my answer for the sake of completeness.

Of course, you should be even more careful with pointer arithmetic if you set that flag.
The statement from Microsoft regarding the end of Internet Explorer 11 support mentions that it will continue to receive security updates, compatibility fixes, and technical support until its end of life. The wording of this statement leads me to believe that Microsoft has no plans to continue adding features to Internet Explorer 11, and instead will be focusing on Edge.
If you require ES6 features in Internet Explorer 11, check out a transpiler such as Babel.
in my case I did
function myFunc() {
console.log('myFunc', $(this));
}
$("selector").on("click", "selector", function(e) {
e.preventDefault();
myFunc.call(this);
});
properly calls myFunc with the correct this.
EL interprets ${class.name} as described - the name becomes getName() on the assumption you are using explicit or implicit methods of generating getter/setters
You can override this behavior by explicitly identifying the name as a function:
${class.name()} This calls the function name() directly without modification.
select count(isnull(NullableColumn,-1))
git-subtree is nice, but it is probably not the one you want.
For example, if projectA is the directory created in B, after git subtree,
git log projectA
lists only one commit: the merge. The commits from the merged project are for different paths, so they don't show up.
Greg Hewgill's answer comes closest, although it doesn't actually say how to rewrite the paths.
The solution is surprisingly simple.
(1) In A,
PREFIX=projectA #adjust this
git filter-branch --index-filter '
git ls-files -s |
sed "s,\t,&'"$PREFIX"'/," |
GIT_INDEX_FILE=$GIT_INDEX_FILE.new git update-index --index-info &&
mv $GIT_INDEX_FILE.new $GIT_INDEX_FILE
' HEAD
Note: This rewrites history; you may want to first make a backup of A.
Note Bene: You have to modify the substitute script inside the sed command in the case that you use non-ascii characters (or white characters) in file names or path. In that case the file location inside a record produced by "ls-files -s" begins with quotation mark.
(2) Then in B, run
git pull path/to/A
Voila! You have a projectA directory in B. If you run git log projectA, you will see all commits from A.
In my case, I wanted two subdirectories, projectA and projectB. In that case, I did step (1) to B as well.
A trunk is considered your main code base, a branch offshoot of the trunk. Like, you create a branch if you want to implement a new feature, but don't want to affect the main trunk.

This appears to be my "preferred" solution:

Sorry for the presentation format - I'm still trying to learn how to use this forum....
I do have a follow-up question. In looking at my MySQL database of URL's it appears that ~30% of the URL's will need to use this post/div wrapper approach. This leaves ~70% that cannot accept the "post" attribute. For example:
<form action="http://www.google.com" method="post">
<div>
<input type="submit" value="Google"/>
</div></form>
does not work. Do you have a recommendation for how to best handle this get/post condition test. Off the top of my head I'm guessing that using PHP to evaluate the existence of the "?" character in the URL may be my best approach, although I'm not sure how to structure the HTML form to accomplish this.
Thank YOU!
I picked this from here
The undefined value is a primitive value used when a variable has not been assigned a value.
The null value is a primitive value that represents the null, empty, or non-existent reference.
When you declare a variable through var and do not give it a value, it will have the value undefined. By itself, if you try to WScript.Echo() or alert() this value, you won't see anything. However, if you append a blank string to it then suddenly it'll appear:
var s;
WScript.Echo(s);
WScript.Echo("" + s);
You can declare a variable, set it to null, and the behavior is identical except that you'll see "null" printed out versus "undefined". This is a small difference indeed.
You can even compare a variable that is undefined to null or vice versa, and the condition will be true:
undefined == null
null == undefined
They are, however, considered to be two different types. While undefined is a type all to itself, null is considered to be a special object value. You can see this by using typeof() which returns a string representing the general type of a variable:
var a;
WScript.Echo(typeof(a));
var b = null;
WScript.Echo(typeof(b));
Running the above script will result in the following output:
undefined
object
Regardless of their being different types, they will still act the same if you try to access a member of either one, e.g. that is to say they will throw an exception. With WSH you will see the dreaded "'varname' is null or not an object" and that's if you're lucky (but that's a topic for another article).
You can explicitely set a variable to be undefined, but I highly advise against it. I recommend only setting variables to null and leave undefined the value for things you forgot to set. At the same time, I really encourage you to always set every variable. JavaScript has a scope chain different than that of C-style languages, easily confusing even veteran programmers, and setting variables to null is the best way to prevent bugs based on it.
Another instance where you will see undefined pop up is when using the delete operator. Those of us from a C-world might incorrectly interpret this as destroying an object, but it is not so. What this operation does is remove a subscript from an Array or a member from an Object. For Arrays it does not effect the length, but rather that subscript is now considered undefined.
var a = [ 'a', 'b', 'c' ];
delete a[1];
for (var i = 0; i < a.length; i++)
WScript.Echo((i+".) "+a[i]);
The result of the above script is:
0.) a
1.) undefined
2.) c
You will also get undefined returned when reading a subscript or member that never existed.
The difference between null and undefined is: JavaScript will never set anything to null, that's usually what we do. While we can set variables to undefined, we prefer null because it's not something that is ever done for us. When you're debugging this means that anything set to null is of your own doing and not JavaScript. Beyond that, these two special values are nearly equivalent.
Is there a good reason not to use a hash? Lookups are O(1) vs. O(n) for the array.
in iOS 11.3 and Swift 4.1
let fetchRequest = NSFetchRequest<NSFetchRequestResult>(entityName: entityName)
let batchDeleteRequest = NSBatchDeleteRequest(fetchRequest: fetchRequest )
batchDeleteRequest.resultType = .resultTypeCount
do {
let batchDeleteResult = try dataController.viewContext.execute(batchDeleteRequest) as! NSBatchDeleteResult
print("The batch delete request has deleted \(batchDeleteResult.result!) records.")
dataController.viewContext.reset() // reset managed object context (need it for working)
} catch {
let updateError = error as NSError
print("\(updateError), \(updateError.userInfo)")
}
you have to call reset after you do execute. If not, it will not update on the table view.
This is rather long post and it gives a more detailed explanation of the issue.
The problem (in my case) comes when you have Multi Slot Content Projection
See also content projection for more info.
For example If you have a component which looks like this:
html file:
<div>
<span>
<ng-content select="my-component-header">
<!-- optional header slot here -->
</ng-content>
</span>
<div class="my-component-content">
<ng-content>
<!-- content slot here -->
</ng-content>
</div>
</div>
ts file:
@Component({
selector: 'my-component',
templateUrl: './my-component.component.html',
styleUrls: ['./my-component.component.scss'],
})
export class MyComponent {
}
And you want to use it like:
<my-component>
<my-component-header>
<!-- this is optional -->
<p>html content here</p>
</my-component-header>
<p>blabla content</p>
<!-- other html -->
</my-component>
And then you get template parse errors that is not a known Angular component and the matter of fact it isn't - it is just a reference to an ng-content in your component:
And then the simplest fix is adding
schemas: [
CUSTOM_ELEMENTS_SCHEMA
],
... to your app.module.ts
But there is an easy and clean approach to this problem - instead of using <my-component-header> to insert html in the slot there - you can use a class name for this task like this:
html file:
<div>
<span>
<ng-content select=".my-component-header"> // <--- Look Here :)
<!-- optional header slot here -->
</ng-content>
</span>
<div class="my-component-content">
<ng-content>
<!-- content slot here -->
</ng-content>
</div>
</div>
And you want to use it like:
<my-component>
<span class="my-component-header"> // <--- Look Here :)
<!-- this is optional -->
<p>html content here</p>
</span>
<p>blabla content</p>
<!-- other html -->
</my-component>
So ... no more components that do not exist so there are no problems in that, no errors, no need for CUSTOM_ELEMENTS_SCHEMA in app.module.ts

You can use IP Webcam, or perhaps use DLNA. For example Samsung devices come with an app called AllShare which can share and access DLNA enabled devices on the network. I think IP Webcam is your best bet, though. You should be able to open the stream it creates using MX Video player or something like that.
Ignoring the refactoring issues, you need to understand functions and return values. You don't need a global at all. Ever. You can do this:
def rps():
# Code to determine if player wins
if player_wins:
return True
return False
Then, just assign a value to the variable outside this function like so:
player_wins = rps()
It will be assigned the return value (either True or False) of the function you just called.
After the comments, I decided to add that idiomatically, this would be better expressed thus:
def rps():
# Code to determine if player wins, assigning a boolean value (True or False)
# to the variable player_wins.
return player_wins
pw = rps()
This assigns the boolean value of player_wins (inside the function) to the pw variable outside the function.
You can use the DateTime class:
$past = new DateTime("2010-01-01 00:00:00");
$now = new DateTime();
$future = new DateTime("2021-01-01 00:00:00");
Comparison operators work*:
var_dump($past < $now); // bool(true)
var_dump($future < $now); // bool(false)
var_dump($now == $past); // bool(false)
var_dump($now == new DateTime()); // bool(true)
var_dump($now == $future); // bool(false)
var_dump($past > $now); // bool(false)
var_dump($future > $now); // bool(true)
It is also possible to grab the timestamp values from DateTime objects and compare them:
var_dump($past ->getTimestamp()); // int(1262286000)
var_dump($now ->getTimestamp()); // int(1431686228)
var_dump($future->getTimestamp()); // int(1577818800)
var_dump($past ->getTimestamp() < $now->getTimestamp()); // bool(true)
var_dump($future->getTimestamp() > $now->getTimestamp()); // bool(true)
* Note that === returns false when comparing two different DateTime objects even when they represent the same date.
Run the app using the simulator
iOS Simulator-> Hardware-> Keyboard -> iOS uses same layout as OS X
This will fix the issue if anyone out there is running their app on their device
Consider also using SETX - it will set variable on user or machine (available for all users) level though the variable will be usable with the next opening of the cmd.exe ,so often it can be used together with SET :
::setting variable for the current user
if not defined My_Var (
set "My_Var=My_Value"
setx My_Var My_Value
)
::setting machine defined variable
if not defined Global_Var (
set "Global_Var=Global_Value"
SetX Global_Var Global_Value /m
)
You can also edit directly the registry values:
User Variables: HKEY_CURRENT_USER\Environment
System Variables: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
Which will allow to avoid some restrictions of SET and SETX like the variables containing = in their names.
I found two ways to handle this. Choose the best for your case. Solutions tested on Firefox 53 and Safari 10.1
1. Detect if user is using the back/foreward button, then reload whole page
if (!!window.performance && window.performance.navigation.type === 2) {
// value 2 means "The page was accessed by navigating into the history"
console.log('Reloading');
window.location.reload(); // reload whole page
}
2. reload whole page if page is cached
window.onpageshow = function (event) {
if (event.persisted) {
window.location.reload();
}
};
If you are using MinGw, rename the mingw32-make.exe to make.exe in the folder " C:\MinGW\bin " or wherever minGw is installed in your system.
Surprisingly this question doesn't have a definitive documented answer. Perhaps another data point would provide value to others looking for an answer. On my systems running CentOS (6.8,7.3) and Java 8 (build 1.8.0_60-b27, 64-Bit Server):
default memory is 1/4 of physical memory, not limited by 1GB.
Also, -XX:+PrintFlagsFinal prints to STDERR so command to determine current default memory presented by others above should be tweaked to the following:
java -XX:+PrintFlagsFinal 2>&1 | grep MaxHeapSize
The following is returned on system with 64GB of physical RAM:
uintx MaxHeapSize := 16873684992 {product}
An old question, but I also have two methods.
For a fixed (predefined) length:
public static String fill(String text) {
if (text.length() >= 10)
return text;
else
return "0000000000".substring(text.length()) + text;
}
For a variable length:
public static String fill(String text, int size) {
StringBuilder builder = new StringBuilder(text);
while (builder.length() < size) {
builder.append('0');
}
return builder.toString();
}
Here, FIND record by MONTH and DATE in mySQL
Here is your POST value $_POST['period']="2012-02";
Just, explode value by dash $Period = explode('-',$_POST['period']);
Get array from explode value :
Array
(
[0] => 2012
[1] => 02
)
Put value in SQL Query:
SELECT * FROM projects WHERE YEAR(Date) = '".$Period[0]."' AND Month(Date) = '".$Period[0]."';
Get Result by MONTH and YEAR.
Quite a few ways to apprach this problem.
Use the box-sizing css3 property and simulate the margins with borders.
div.inside {
width: 25%;
float:left;
border-right: 5px solid grey;
background-color: blue;
box-sizing:border-box;
-moz-box-sizing:border-box; /* Firefox */
-webkit-box-sizing:border-box; /* Safari */
}
<div style="width:100%; height: 200px; background-color: grey;">
<div class="inside">A</div>
<div class="inside">B</div>
<div class="inside">C</div>
<div class="inside">D</div>
</div>
Reduce the percentage of your elements widths and add some margin-right.
.outer {
width:100%;
background:#999;
overflow:auto;
}
.inside {
float:left;
width:24%;
margin-right:1%;
background:#333;
}
You will have to modify the below line:
<li><a href="#" data-toggle="modal" data-target="modalRegister">Register</a></li>
modalRegister is the ID and hence requires a preceding # for ID reference in html.
So, the modified html code snippet would be as follows:
<li><a href="#" data-toggle="modal" data-target="#modalRegister">Register</a></li>
I've just had this problem with MariaDB/InnoDB and was able to fix it by
If you want to have your ls colorized you have to edit your ~/.bash_profile file and add the following line (if not already written) :
source .bashrc
Then you edit or create ~/.bashrc file and write an alias to the ls command :
alias ls="ls -G"
Now you have to type source .bashrc in a terminal if already launched, or simply open a new terminal.
If you want more options in your ls juste read the manual ( man ls ). Options are not exactly the same as in a GNU/Linux system.
Taken from the MySQL 8.0 Reference Manual:
utf8mb4: A UTF-8 encoding of the Unicode character set using one to four bytes per character.
utf8mb3: A UTF-8 encoding of the Unicode character set using one to three bytes per character.
In MySQL utf8 is currently an alias for utf8mb3 which is deprecated and will be removed in a future MySQL release. At that point utf8 will become a reference to utf8mb4.
So regardless of this alias, you can consciously set yourself an utf8mb4 encoding.
To complete the answer, I'd like to add the @WilliamEntriken's comment below (also taken from the manual):
To avoid ambiguity about the meaning of
utf8, consider specifyingutf8mb4explicitly for character set references instead ofutf8.
You did everything correctly!
You might also change the email configuration, depending on if the email server is also the same server. The email configuration is in gitlab.yml for the mails sent by GitLab and also the admin-email.
Mine was a name spacing issue. I had two files with the same name. Just renamed them and it resolved.
Always gotta check the 'stupid me' box first before looking elsewhere. : )
You can use the wildcard pattern matching characters as literal characters. To use a wildcard character as a literal character, enclose the wildcard character in brackets. The following table shows several examples of using the LIKE keyword and the [ ] wildcard characters.
For your case:
... LIKE '%[_]d'
if($scope.test == null || $scope.test == undefined || $scope.test == "" || $scope.test.lenght == 0){
console.log("test is not defined");
}
else{
console.log("test is defined ",$scope.test);
}
If you are in a directory where only root have access to write in system. Then you can directly use wget www.example.com/wget-test using a standard user account. So it will hit the url but because of having no write permission file won't be saved..
This method is working fine for me as i am using this method for a cronjob.

To ensure that JQuery isn't caching the results, on your ajax methods, put the following:
$.ajax({
cache: false
//rest of your ajax setup
});
Or to prevent caching in MVC, we created our own attribute, you could do the same. Here's our code:
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
public sealed class NoCacheAttribute : ActionFilterAttribute
{
public override void OnResultExecuting(ResultExecutingContext filterContext)
{
filterContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
filterContext.HttpContext.Response.Cache.SetValidUntilExpires(false);
filterContext.HttpContext.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
filterContext.HttpContext.Response.Cache.SetNoStore();
base.OnResultExecuting(filterContext);
}
}
Then just decorate your controller with [NoCache]. OR to do it for all you could just put the attribute on the class of the base class that you inherit your controllers from (if you have one) like we have here:
[NoCache]
public class ControllerBase : Controller, IControllerBase
You can also decorate some of the actions with this attribute if you need them to be non-cacheable, instead of decorating the whole controller.
If your class or action didn't have NoCache when it was rendered in your browser and you want to check it's working, remember that after compiling the changes you need to do a "hard refresh" (Ctrl+F5) in your browser. Until you do so, your browser will keep the old cached version, and won't refresh it with a "normal refresh" (F5).

Also compared to yoshisurfs answer, most of the time when mysql gets installed the mysql directory should be renamed to just mysql, not the whole file name, for ease of use.

Use this to get the page scroll position.
var screenTop = $(document).scrollTop();
$('#content').css('top', screenTop);
Try like this:

Empty variables are $null and then different from "" ([string]::empty).
I needed to use Java embedded database in one of my projects and I did lot of research understanding pros and cons of each database. I wrote a blog listing pros and cons of popular embedded java databases (H2, HSQLDB, Derby, ObjectDB, Neo4j, OrientDB), you can have a look at it. I chose H2 as I thought it best suited my requirements. Link for the blog: http://sayrohan.blogspot.in/2012/12/choosing-light-weight-java-database.html Hope it helps!
Consider you want to pass a custom attribute named myAttr with value myValue, this will work:
<MyComponent data-myAttr={myValue} />
Make sure
{!! csrf_field() !!}
is added within your form in blade syntax.
or in simple form syntax
<input type="hidden" name="_token" value="{{ csrf_token() }}">
along with this, make sure, in session.php (in config folder), following is set correctly.
'domain' => env('SESSION_DOMAIN', 'sample-project.com'),
or update the same in .env file like,
SESSION_DOMAIN=sample-project.com
In my case {!! csrf_field() !!} was added correctly but SESSION_DOMAIN was not configured correctly. After I changed it with correct value in my .env file, it worked.
I am answering this question after 4-5 years but best practices to do this as below
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<LinearLayout
android:id="@+id/firstLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_toLeftOf="@+id/secondView"
android:orientation="vertical"></LinearLayout>
<View
android:id="@+id/secondView"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_centerHorizontal="true" />
<LinearLayout
android:id="@+id/thirdLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_toRightOf="@+id/secondView"
android:orientation="vertical"></LinearLayout>
</RelativeLayout>
This is right approach as use of layout_weight is always heavy for UI operations. Splitting Layout equally using LinearLayout is not good practice
It is possible to turn the string into a stream by using the std::stringstream class (its constructor takes a string as parameter). Once it's built, you can use the >> operator on it (like on regular file based streams), which will extract, or tokenize word from it:
#include <iostream>
#include <sstream>
using namespace std;
int main(){
string line = "test one two three.";
string arr[4];
int i = 0;
stringstream ssin(line);
while (ssin.good() && i < 4){
ssin >> arr[i];
++i;
}
for(i = 0; i < 4; i++){
cout << arr[i] << endl;
}
}
Promise can be cancelled with the help of AbortController.
Is there a method for clearing then: yes you can reject the promise with
AbortControllerobject and then thepromisewill bypass all then blocks and go directly to the catch block.
Example:
import "abortcontroller-polyfill";
let controller = new window.AbortController();
let signal = controller.signal;
let elem = document.querySelector("#status")
let example = (signal) => {
return new Promise((resolve, reject) => {
let timeout = setTimeout(() => {
elem.textContent = "Promise resolved";
resolve("resolved")
}, 2000);
signal.addEventListener('abort', () => {
elem.textContent = "Promise rejected";
clearInterval(timeout);
reject("Promise aborted")
});
});
}
function cancelPromise() {
controller.abort()
console.log(controller);
}
example(signal)
.then(data => {
console.log(data);
})
.catch(error => {
console.log("Catch: ", error)
});
document.getElementById('abort-btn').addEventListener('click', cancelPromise);
Html
<button type="button" id="abort-btn" onclick="abort()">Abort</button>
<div id="status"> </div>
Note: need to add polyfill, not supported in all browser.
Live Example
Try this instead in the end:
exec (@query)
If you do not have the brackets, SQL Server assumes the value of the variable to be a stored procedure name.
OR
EXECUTE sp_executesql @query
And it should not be because of FULL JOIN.
But I hope you have already created the temp tables: #TrafficFinal, #TrafficFinal2, #TrafficFinal3 before this.
Please note that there are performance considerations between using EXEC and sp_executesql. Because sp_executesql uses forced statement caching like an sp.
More details here.
On another note, is there a reason why you are using dynamic sql for this case, when you can use the query as is, considering you are not doing any query manipulations and executing it the way it is?
Expanding on "Short and Fast" above by @Adam Leggett, as cases like "02/30/2020" return true when it should be false. I really dig the bitmap though...

Create a python dictionary to return as the response:
response = {'key': 'value'}
Then you can use json.dumps() or flask.jsonify() to turn a python dictionary into JSON:
from json import dumps
return dumps(response)
from flask import jsonify
return jsonify(response)
Note that flask.jsonify() is made for flask and also it has some more advatages. You can use it like in the following code:
from flask import jsonify
params = {
'key': 'value'
}
return jsonify(**params)
This is like using the following line:
return jsonify(key='value')
Remeber in this code you don't need the response dictionary!
Much faster hashing should be possible by calculating on graphic card (implement hashing algorithm in WebGL), as discussed there about SHA256: Is it possible to calculate sha256 hashes in the browser using the user's video card, eg. by using WebGL or Flash?
this is the updated answer for WAMP v3.0.6
UPDATE mysql.user
SET authentication_string=PASSWORD('MyNewPass')
WHERE user='root';
FLUSH PRIVILEGES;
I think this could be done in a much simpler way:
So code would look something like this:
WebElement month = driver.findElement(month combo locator);
Select monthCombo = new Select(month);
monthCombo.selectByVisibleText("March");
WebElement year = driver.findElement(year combo locator);
Select yearCombo = new Select(year);
yearCombo.selectByVisibleText("2015");
driver.click(By.linkText("31"));
This won't work if the date picker dropdowns are not Select, but most of the ones I've seen are individual elements (select, links, etc.)
You use the Headers property with a string index:
request.Headers["X-My-Custom-Header"] = "the-value";
According to MSDN, this has been available since:
https://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.headers(v=vs.110).aspx
In Python 3.0–3.3 you would use: imp.reload(module)
The BDFL has answered this question.
However, imp was deprecated in 3.4, in favour of importlib (thanks @Stefan!).
I think, therefore, you’d now use importlib.reload(module), although I’m not sure.
I use this method:
$(function() {
return $(".modal").on("show.bs.modal", function() {
var curModal;
curModal = this;
$(".modal").each(function() {
if (this !== curModal) {
$(this).modal("hide");
}
});
});
});
One line version: long n = strtol(s.c_str(), NULL, base); .
(s is the string, and base is an int such as 2, 8, 10, 16.)
You can refer to this link for more details of strtol.
The core idea is to use strtol function, which is included in cstdlib.
Since strtol only handles with char array, we need to convert string to char array. You can refer to this link.
An example:
#include <iostream>
#include <string> // string type
#include <bitset> // bitset type used in the output
int main(){
s = "1111000001011010";
long t = strtol(s.c_str(), NULL, 2); // 2 is the base which parse the string
cout << s << endl;
cout << t << endl;
cout << hex << t << endl;
cout << bitset<16> (t) << endl;
return 0;
}
which will output:
1111000001011010
61530
f05a
1111000001011010
First of all, link_to is a html tag helper, its second argument is the url, followed by html_options. What you would like is to pass account_id as a url parameter to the path. If you have set up named routes correctly in routes.rb, you can use path helpers.
link_to "+ Service", new_my_service_path(:account_id => acct.id)
I think the best practice is to pass model values as a param nested within :
link_to "+ Service", new_my_service_path(:my_service => { :account_id => acct.id })
# my_services_controller.rb
def new
@my_service = MyService.new(params[:my_service])
end
And you need to control that account_id is allowed for 'mass assignment'. In rails 3 you can use powerful controls to filter valid params within the controller where it belongs. I highly recommend.
http://apidock.com/rails/ActiveModel/MassAssignmentSecurity/ClassMethods
Also note that if account_id is not freely set by the user (e.g., a user can only submit a service for the own single account_id, then it is better practice not to send it via the request, but set it within the controller by adding something like:
@my_service.account_id = current_user.account_id
You can surely combine the two if you only allow users to create service on their own account, but allow admin to create anyone's by using roles in attr_accessible.
hope this helps
uos??'s answer is fundamentally correct, but you probably don't want to do it in the mouseenter event. That's going to cause it to do the calculation to determine if it's needed, each time you mouse over the element. Unless the size of the element is changing, there's no reason to do that.
It would be better to just call this code immediately after the element is added to the DOM:
var $ele = $('#mightOverflow');
var ele = $ele.eq(0);
if (ele.offsetWidth < ele.scrollWidth)
$ele.attr('title', $ele.text());
Or, if you don't know when exactly it's added, then call that code after the page is finished loading.
if you have more than a single element that you need to do this with, then you can give them all the same class (such as "mightOverflow"), and use this code to update them all:
$('.mightOverflow').each(function() {
var $ele = $(this);
if (this.offsetWidth < this.scrollWidth)
$ele.attr('title', $ele.text());
});
The expression a == b should do the job.
You have to set CommandTimeout attribute. You can set the CommandTimeout attribute in DbContext child class.
public partial class StudentDatabaseEntities : DbContext
{
public StudentDatabaseEntities()
: base("name=StudentDatabaseEntities")
{
this.Database.CommandTimeout = 180;
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
throw new UnintentionalCodeFirstException();
}
public virtual DbSet<StudentDbTable> StudentDbTables { get; set; }
}
Just compare the year, month and day values.
Declare @DateToSearch DateTime
Set @DateToSearch = '14 AUG 2008'
SELECT *
FROM table1
WHERE Year(column_datetime) = Year(@DateToSearch)
AND Month(column_datetime) = Month(@DateToSearch)
AND Day(column_datetime) = Day(@DateToSearch)
If you are creating custom buttons, e.g. see change look of checkbox tutorial
Then simply increase the width of btn_check_label_background.9.png by adding one or two more columns of transparent pixels in the center of the image; leave the 9-patch markers as they are.
In my case, it was neither systemd nor a cron job, but it was snap. So I had to run:
sudo snap stop docker
sudo snap remove docker
... and the last command actually never ended, I don't know why: this snap thing is really a pain. So I also ran:
sudo apt purge snap
:-)
You could get around this issue using php. You only echo out the code for the popup on first page load.
The other way... Is to set a cookie which is basically a file that sits in your browser and contains some kind of data. On the first page load you would create a cookie. Then every page after that you check if your cookie is set. If it is set do not display the pop up. However if its not set set the cookie and display the popup.
Pseudo code:
if(cookie_is_not_set) {
show_pop_up;
set_cookie;
}
I think scala-optparse-applicative is the most functional command line parser library in Scala.
I know the topic is a bit old and seems stale, but anyway I was able to use these options:
deploy:
resources:
limits:
cpus: '0.001'
memory: 50M
when using 3.7 version of docker-compose
What helped in my case, was using this command:
docker-compose --compatibility up
--compatibility flag stands for (taken from the documentation):
If set, Compose will attempt to convert deploy keys in v3 files to their non-Swarm equivalent
Think it's great, that I don't have to revert my docker-compose file back to v2.
You need to use a raw string, double your slashes or use forward slashes instead:
r'C:\Users\expoperialed\Desktop\Python'
'C:\\Users\\expoperialed\\Desktop\\Python'
'C:/Users/expoperialed/Desktop/Python'
In regular python strings, the \U character combination signals a extended Unicode codepoint escape.
You can hit any number of other issues, for any of the recognised escape sequences, such as \a or \t or \x, etc.
The advantages of CXF:
The advantages of Axis2:
In Summary: From above advantage items, it brings us to a good thoughts to compare Axis2 and CXF on their own merits. they all have different well-developed areas in a certain field, CXF is very configurable, integratable and has rich tool kits supported and close to Java community, Axis2 has taken an approach that makes it in many ways resemble an application server in miniature. it is across multiple programming languages. because its Independence, Axis2 lends itself towards web services that stand alone, independent of other applications, and offers a wide variety of functionality.
As a developer, we need to accord our perspective to choose the right one, whichever framework you choose, you’ll have the benefit of an active and stable open source community. In terms of performance, I did a test based the same functionality and configed in the same web container, the result shows that CXF performed little bit better than Axis2, the single case may not exactly reflect their capabilities and performance.
In some research articles, it reveals that Axis2's proprietary ADB databinding is a bit faster than CXF since it don’t have additional feature(WS-Security). Apache AXIS2 is relatively most used framework but Apache CXF scores over other Web Services Framework comparatively considering ease of development, current industry trend, performance, overall scorecard and other features (unless there is Web Services Orchestration support is explicitly needed, which is not required here)
Even user has got answer and @Michael - sqlbot has covered mostly points very well in his post but one point is missing, so just trying to cover it.
If you want to provide read permission to a simple user (Not admin kind of)-
GRANT SELECT, EXECUTE ON DB_NAME.* TO 'user'@'localhost' IDENTIFIED BY 'PASSWORD';
Note: EXECUTE is required here, so that user can read data if there is a stored procedure which produce a report (have few select statements).
Replace localhost with specific IP from which user will connect to DB.
Additional Read Permissions are-
I tried the first few solutions and didn't work for me. Mainly the problem with attributes being removed like the other have already mentioned. I would say my approach is very similar to Jimmy by using the XElement constructors that taking object as parameters.
public static XElement RemoveAllNamespaces(this XElement element)
{
return new XElement(element.Name.LocalName,
element.HasAttributes ? element.Attributes().Select(a => new XAttribute(a.Name.LocalName, a.Value)) : null,
element.HasElements ? element.Elements().Select(e => RemoveAllNamespaces(e)) : null,
element.Value);
}
The easiest way if you have
<div ng-repeat="person in data | filter: query"></div>
Filtered data length
<div>{{ (data | filter: query).length }}</div>
An IEEE double has 53 significant bits (that's the value of DBL_MANT_DIG in <cfloat>). That's approximately 15.95 decimal digits (log10(253)); the implementation sets DBL_DIG to 15, not 16, because it has to round down. So you have nearly an extra decimal digit of precision (beyond what's implied by DBL_DIG==15) because of that.
The nextafter() function computes the nearest representable number to a given number; it can be used to show just how precise a given number is.
This program:
#include <cstdio>
#include <cfloat>
#include <cmath>
int main() {
double x = 1.0/7.0;
printf("FLT_RADIX = %d\n", FLT_RADIX);
printf("DBL_DIG = %d\n", DBL_DIG);
printf("DBL_MANT_DIG = %d\n", DBL_MANT_DIG);
printf("%.17g\n%.17g\n%.17g\n", nextafter(x, 0.0), x, nextafter(x, 1.0));
}
gives me this output on my system:
FLT_RADIX = 2
DBL_DIG = 15
DBL_MANT_DIG = 53
0.14285714285714282
0.14285714285714285
0.14285714285714288
(You can replace %.17g by, say, %.64g to see more digits, none of which are significant.)
As you can see, the last displayed decimal digit changes by 3 with each consecutive value. The fact that the last displayed digit of 1.0/7.0 (5) happens to match the mathematical value is largely coincidental; it was a lucky guess. And the correct rounded digit is 6, not 5. Replacing 1.0/7.0 by 1.0/3.0 gives this output:
FLT_RADIX = 2
DBL_DIG = 15
DBL_MANT_DIG = 53
0.33333333333333326
0.33333333333333331
0.33333333333333337
which shows about 16 decimal digits of precision, as you'd expect.
Not knowing exactly what you're trying to achieve, I would suggest looking into the possibility of redesigning you application to use composition rather than inheritance in this case.
{{ path(app.request.attributes.get('_route'),
app.request.attributes.get('_route_params')) }}
If you want to read it into a view variable:
{% set currentPath = path(app.request.attributes.get('_route'),
app.request.attributes.get('_route_params')) %}
The app global view variable contains all sorts of useful shortcuts, such as app.session and app.security.token.user, that reference the services you might use in a controller.
Also happens when you forget to change the ConnectionString and ask a table that has no idea about the changes you're making locally.
A better way, use getParent() from File Class..
String a="/root/sdcard/Pictures/img0001.jpg"; // A valid file path
File file = new File(a);
String getDirectoryPath = file.getParent(); // Only return path if physical file exist else return null
http://developer.android.com/reference/java/io/File.html#getParent%28%29
File name without file extension when you don't know that extension:
$basename = substr($filename, 0, strrpos($filename, "."));
None of the above worked for me on an Ubuntu 18.04 fresh install via docker image.
The following solved it for me:
apt-get install holland python3-mysqldb
For anyone willing to try a different method, they can use this:
select FORMAT([Column_Name], '') from YourTable
This will easily change any float value to nvarchar.
I am amazed at how complex this question has become.
These are all identical, and their integer values all === EPOCH time :D
console.log((new Date()).getTime() / 1000, new Date().valueOf() / 1000, (new Date() - new Date().getTimezoneOffset() * 60 * 1000) / 1000);
Do not believe me, checkout: http://www.epochconverter.com/

Which is pretty much straight forward install, fast gem updates and followups and quick fixes in case is needed.
Definitely the HTML5 element is the way to go. There's at least basic support for it in the most recent versions of almost all browsers:
http://caniuse.com/#feat=audio
And it allows to specify what to do when the element is not supported by the browser. For example you could add a link to a file by doing:
<audio controls src="intro.mp3">
<a href="intro.mp3">Introduction to HTML5 (10:12) - MP3 - 3.2MB</a>
</audio>
You can find this examples and more information about the audio element in the following link:
http://hacks.mozilla.org/2012/04/enhanceyourhtml5appwithaudio/
Finally, the good news are that mozilla's April's dev Derby is about this element so that's probably going to provide loads of great examples of how to make the most out of this element:

Use the @RequestParam to pass a parameter to the controller handler method.
In the jsp your form should have an input field with name = "id" like the following:
<input type="text" name="id" />
<input type="submit" />
Then in your controller, your handler method should be like the following:
@RequestMapping("listNotes")
public String listNotes(@RequestParam("id") int id) {
Person person = personService.getCurrentlyAuthenticatedUser();
model.addAttribute("person", new Person());
model.addAttribute("listPersons", this.personService.listPersons());
model.addAttribute("listNotes", this.notesService.listNotesBySectionId(id, person));
return "note";
}
Please also refer to these answers and tutorial:
I agree with @pkozlowski.opensource answer, but ng-clock class did't work for me for using with ng-repeat. so I would like to recommend you to use class for simple delimiter expression like {{name}} and ngCloak directive for ng-repeat.
<div class="ng-cloak">{{name}}<div>
and
<li ng-repeat="item in items" ng-cloak>{{item.name}}<li>
