I recommend Pygments. It accepts a piece of code in any language and outputs syntax highlighted LaTeX code. It uses fancyvrb and color packages to produce its output. I personally prefer it to the listing package. I think fancyvrb creates much prettier results.
This is probably being caused by CRLF issues.
See: Why should I use core.autocrlf=true in Git?
Use this to pull and force update:

removing JAVA_HOME and JAVA_JRE from environment variable is resolved the issue.

Update alpha 47
As of alpha 47 the below answer (for alpha46 and below) is not longer required. Now the Http module handles automatically the errores returned. So now is as easy as follows
http
.get('Some Url')
.map(res => res.json())
.subscribe(
(data) => this.data = data,
(err) => this.error = err); // Reach here if fails
Alpha 46 and below
You can handle the response in the map(...), before the subscribe.
http
.get('Some Url')
.map(res => {
// If request fails, throw an Error that will be caught
if(res.status < 200 || res.status >= 300) {
throw new Error('This request has failed ' + res.status);
}
// If everything went fine, return the response
else {
return res.json();
}
})
.subscribe(
(data) => this.data = data, // Reach here if res.status >= 200 && <= 299
(err) => this.error = err); // Reach here if fails
Here's a plnkr with a simple example.
Note that in the next release this won't be necessary because all status codes below 200 and above 299 will throw an error automatically, so you won't have to check them by yourself. Check this commit for more info.
Here's a simple function -
function getNumberFromCurrency(currency) {
return Number(currency.replace(/[$,]/g,''))
}
console.log(getNumberFromCurrency('$1,000,000.99')) // 1000000.99Here is a function that I have in my PowerShell profile for loading SQL snapins:

Try this:
string keyvalue = System.Configuration.ConfigurationManager.AppSettings["keyname"];
In the web.config file this should be the next structure:

For hash references. You should use curly braces like the following:
$hash_ref1 = {%$hash_ref1, %$hash_ref2};
and not the suggested answer above using parenthesis:
$hash_ref1 = ($hash_ref1, $hash_ref2);
AFAIK the files in the assets directory don't get unpacked. Instead, they are read directly from the APK (ZIP) file.
So, you really can't make stuff that expects a file accept an asset 'file'.
Instead, you'll have to extract the asset and write it to a seperate file, like Dumitru suggests:
File f = new File(getCacheDir()+"/m1.map");
if (!f.exists()) try {
InputStream is = getAssets().open("m1.map");
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
FileOutputStream fos = new FileOutputStream(f);
fos.write(buffer);
fos.close();
} catch (Exception e) { throw new RuntimeException(e); }
mapView.setMapFile(f.getPath());
If you have an ES2015 environment (as of this writing: io.js, IE11, Chrome, Firefox, WebKit nightly), then the following will work, and will be fast (viz. O(n)):
function hasDuplicates(array) {
return (new Set(array)).size !== array.length;
}
If you only need string values in the array, the following will work:
function hasDuplicates(array) {
var valuesSoFar = Object.create(null);
for (var i = 0; i < array.length; ++i) {
var value = array[i];
if (value in valuesSoFar) {
return true;
}
valuesSoFar[value] = true;
}
return false;
}
We use a "hash table" valuesSoFar whose keys are the values we've seen in the array so far. We do a lookup using in to see if that value has been spotted already; if so, we bail out of the loop and return true.
If you need a function that works for more than just string values, the following will work, but isn't as performant; it's O(n2) instead of O(n).
function hasDuplicates(array) {
var valuesSoFar = [];
for (var i = 0; i < array.length; ++i) {
var value = array[i];
if (valuesSoFar.indexOf(value) !== -1) {
return true;
}
valuesSoFar.push(value);
}
return false;
}
The difference is simply that we use an array instead of a hash table for valuesSoFar, since JavaScript "hash tables" (i.e. objects) only have string keys. This means we lose the O(1) lookup time of in, instead getting an O(n) lookup time of indexOf.
You don't need that sort of solution for string literals, since they are concatenated at the language level, and it wouldn't work anyway because "s""1" isn't a valid preprocessor token.
[Edit: In response to the incorrect "Just for the record" comment below that unfortunately received several upvotes, I will reiterate the statement above and observe that the program fragment
#define PPCAT_NX(A, B) A ## B
PPCAT_NX("s", "1")
produces this error message from the preprocessing phase of gcc: error: pasting ""s"" and ""1"" does not give a valid preprocessing token
]
However, for general token pasting, try this:
/*
* Concatenate preprocessor tokens A and B without expanding macro definitions
* (however, if invoked from a macro, macro arguments are expanded).
*/
#define PPCAT_NX(A, B) A ## B
/*
* Concatenate preprocessor tokens A and B after macro-expanding them.
*/
#define PPCAT(A, B) PPCAT_NX(A, B)
Then, e.g., both PPCAT_NX(s, 1) and PPCAT(s, 1) produce the identifier s1, unless s is defined as a macro, in which case PPCAT(s, 1) produces <macro value of s>1.
Continuing on the theme are these macros:
/*
* Turn A into a string literal without expanding macro definitions
* (however, if invoked from a macro, macro arguments are expanded).
*/
#define STRINGIZE_NX(A) #A
/*
* Turn A into a string literal after macro-expanding it.
*/
#define STRINGIZE(A) STRINGIZE_NX(A)
Then,
#define T1 s
#define T2 1
STRINGIZE(PPCAT(T1, T2)) // produces "s1"
By contrast,
STRINGIZE(PPCAT_NX(T1, T2)) // produces "T1T2"
STRINGIZE_NX(PPCAT_NX(T1, T2)) // produces "PPCAT_NX(T1, T2)"
#define T1T2 visit the zoo
STRINGIZE(PPCAT_NX(T1, T2)) // produces "visit the zoo"
STRINGIZE_NX(PPCAT(T1, T2)) // produces "PPCAT(T1, T2)"
In most of the general cases 'Length' and 'Count' are used.
Array:
int[] myArray = new int[size];
int noOfElements = myArray.Length;
Typed List Array:
List <int> myArray = new List<int>();
int noOfElements = myArray.Count;
I don't think there is a way to ignore adding DEFINERs to the dump. But there are ways to remove them after the dump file is created.
Open the dump file in a text editor and replace all occurrences of DEFINER=root@localhost with an empty string ""
Edit the dump (or pipe the output) using perl:
perl -p -i.bak -e "s/DEFINER=\`\w.*\`@\`\d[0-3].*[0-3]\`//g" mydatabase.sql
mysqldump ... | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' > triggers_backup.sql
If you are simply checking for the existence of an ID, there is no need to go into jQuery, you could simply:
if(document.getElementById("yourid") !== null)
{
}
getElementById returns null if it can't be found.
If however you plan to use the jQuery object later i'd suggest:
$(document).ready(function() {
var $myDiv = $('#DivID');
if ( $myDiv.length){
//you can now reuse $myDiv here, without having to select it again.
}
});
A selector always returns a jQuery object, so there shouldn't be a need to check against null (I'd be interested if there is an edge case where you need to check for null - but I don't think there is).
If the selector doesn't find anything then length === 0 which is "falsy" (when converted to bool its false). So if it finds something then it should be "truthy" - so you don't need to check for > 0. Just for it's "truthyness"
Another case where it's usually okay is in a reporting database, where data is perhaps already aged and writes just don't happen. In this case, though, the option should be set at the database or table level by the administrator by changing the default isolation level.
In the general case: you can use it when you are very sure that it's okay to read old data. The important thing to remember is that its very easy to get that wrong. For example, even if it's okay at the time you write the query, are you sure something won't change in the database in the future to make these updates more important?
I'll also 2nd the notion that it's probably not a good idea in banking app. Or inventory app. Or anywhere you're thinking about transactions.
I got such a problem after I upgraded my node version with brew. To fix the problem
1)run $brew doctor to check out if it is successfully installed or not
2) In case you missed clearing any node-related file before, such error log might pop up:
Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built.
node
3) Now you are recommended to run brew link command to delete the original node-related files and overwrite new files - $ brew link node.
And that's it - everything works again !!!
I haven't done time test with this but it was fun to try. Basically convert two columns to one column of tuples. Now convert that to a dataframe, do 'value_counts()' which finds the unique elements and counts them. Fiddle with zip again and put the columns in order you want. You can probably make the steps more elegant but working with tuples seems more natural to me for this problem
b = pd.DataFrame({'A':['yes','yes','yes','yes','no','no','yes','yes','yes','no'],'B':['yes','no','no','no','yes','yes','no','yes','yes','no']})
b['count'] = pd.Series(zip(*[b.A,b.B]))
df = pd.DataFrame(b['count'].value_counts().reset_index())
df['A'], df['B'] = zip(*df['index'])
df = df.drop(columns='index')[['A','B','count']]

comments welcome.
If you are running a recent Linux OS with SystemD, you can use the SystemD Timer unit to run your script at any granularity level you wish (theoretically down to nanoseconds), and - if you wish - much more flexible launching rules than Cron ever allowed. No sleep kludges required
It takes a bit more to set up than a single line in a cron file, but if you need anything better than "Every minute", it is well worth the effort.
The SystemD timer model is basically this: timers are units that start service units when a timer elapses.
So for every script/command that you want to schedule, you must have a service unit and then an additional timer unit. A single timer unit can include multiple schedules, so you normally wouldn't need more than one timer and one service.
Here is a simple example that logs "Hello World" every 10 seconds:
/etc/systemd/system/helloworld.service:
[Unit]
Description=Say Hello
[Service]
ExecStart=/usr/bin/logger -i Hello World
/etc/systemd/system/helloworld.timer:
[Unit]
Description=Say Hello every 10 seconds
[Timer]
OnBootSec=10
OnUnitActiveSec=10
AccuracySec=1ms
[Install]
WantedBy=timers.target
After setting up these units (in /etc/systemd/system, as described above, for a system-wide setting, or at ~/.config/systemd/user for a user-specific setup), you need to enable the timer (not the service though) by running systemctl enable --now helloworld.timer (the --now flag also starts the timer immediately, otherwise, it will only start after the next boot, or user login).
The [Timer] section fields used here are as follows:
OnBootSec - start the service this many seconds after each boot.OnUnitActiveSec - start the service this many seconds after the last time the service was started. This is what causes the timer to repeat itself and behave like a cron job.AccuracySec - sets the accuracy of the timer. Timers are only as accurate as this field sets, and the default is 1 minute (emulates cron). The main reason to not demand the best accuracy is to improve power consumption - if SystemD can schedule the next run to coincide with other events, it needs to wake the CPU less often. The 1ms in the example above is not ideal - I usually set accuracy to 1 (1 second) in my sub-minute scheduled jobs, but that would mean that if you look at the log showing the "Hello World" messages, you'd see that it is often late by 1 second. If you're OK with that, I suggest setting the accuracy to 1 second or more.As you may have noticed, this timer doesn't mimic Cron all that well - in the sense that the command doesn't start at the beginning of every wall clock period (i.e. it doesn't start on the 10th second on the clock, then the 20th and so on). Instead is just happens when the timer ellapses. If the system booted at 12:05:37, then the next time the command runs will be at 12:05:47, then at 12:05:57, etc. If you are interested in actual wall clock accuracy, then you may want to replace the OnBootSec and OnUnitActiveSec fields and instead set an OnCalendar rule with the schedule that you want (which as far as I understand can't be faster than 1 second, using the calendar format). The above example can also be written as:
OnCalendar=*-*-* *:*:00,10,20,30,40,50
Last note: as you probably guessed, the helloworld.timer unit starts the helloworld.service unit because they have the same name (minus the unit type suffix). This is the default, but you can override that by setting the Unit field for the [Timer] section.
More gory details can be found at:
man systemd.timerman systemd.timeman systemd.serviceman system.execThe ActionBar ID is not available directly, so you have to do little bit of hacking here.
int actionBarTitleId = Resources.getSystem().getIdentifier("action_bar_title", "id", "android");
if (actionBarTitleId > 0) {
TextView title = (TextView) findViewById(actionBarTitleId);
if (title != null) {
title.setTextColor(Color.RED);
}
}
You can try to restore your previous state by doing the following:
Here's a slightly modified version of TibTibs':
function serialize(form) {
var field, s = [];
if (typeof form == 'object' && form.nodeName == "FORM") {
var len = form.elements.length;
for (i=0; i<len; i++) {
field = form.elements[i];
if (field.name && !field.disabled && field.type != 'file' && field.type != 'reset' && field.type != 'submit' && field.type != 'button') {
if (field.type == 'select-multiple') {
for (j=form.elements[i].options.length-1; j>=0; j--) {
if(field.options[j].selected)
s[s.length] = encodeURIComponent(field.name) + "=" + encodeURIComponent(field.options[j].value);
}
} else if ((field.type != 'checkbox' && field.type != 'radio') || field.checked) {
s[s.length] = encodeURIComponent(field.name) + "=" + encodeURIComponent(field.value);
}
}
}
}
return s.join('&').replace(/%20/g, '+');
}
Disabled fields are discarded and names are also URL encoded. Regex replace of %20 characters takes place only once, before returning the string.
The query string is in identical form to the result from jQuery's $.serialize() method.

This should answer Greg's question.
Change your getTaskCount Method to this:
public int getTaskCount(long tasklist_id){
SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor= db.rawQuery("SELECT COUNT (*) FROM " + TABLE_TODOTASK + " WHERE " + KEY_TASK_TASKLISTID + "=?", new String[] { String.valueOf(tasklist_id) });
cursor.moveToFirst();
int count= cursor.getInt(0);
cursor.close();
return count;
}
Then, update the click handler accordingly:
public void onItemClick(AdapterView<?> arg0, android.view.View v, int position, long id) {
db = new TodoTask_Database(getApplicationContext());
// Get task list id
int tasklistid = adapter.getItem(position).getTaskListId();
if(db.getTaskCount(tasklistid) > 0) {
System.out.println(c);
Intent taskListID = new Intent(getApplicationContext(), AddTask_List.class);
taskListID.putExtra("TaskList_ID", tasklistid);
startActivity(taskListID);
} else {
Intent addTask = new Intent(getApplicationContext(), Add_Task.class);
startActivity(addTask);
}
}
Instead of writing the very long:
=OFFSET(INDIRECT(ADDRESS(ROW(), COLUMN())),0,-1)
You can simply write:
=OFFSET(*Name of your Cell*,0,-1)
Thus for example you can write into Cell B2:
=OFFSET(B2,0,-1)
to reference to cell B1
Still thanks Jason Young!! I would have never come up with this solution without your answer!
One correct way to get selected value would be
var selected_value = $('#fruit_name').val()
And then you should do

What I do on my cloud instances is I redirect port 80 to port 3000 with this command:
sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3000
Then I launch my Node.js on port 3000. Requests to port 80 will get mapped to port 3000.
You should also edit your /etc/rc.local file and add that line minus the sudo. That will add the redirect when the machine boots up. You don't need sudo in /etc/rc.local because the commands there are run as root when the system boots.
Use the forever module to launch your Node.js with. It will make sure that it restarts if it ever crashes and it will redirect console logs to a file.
Add your Node.js start script to the file you edited for port redirection, /etc/rc.local. That will run your Node.js launch script when the system starts.
This not only applies to Linode, but Digital Ocean, AWS EC2 and other VPS providers as well. However, on RedHat based systems /etc/rc.local is /ect/rc.d/local.
Just to complete the example with a full implementation of ClientHttpRequestInterceptor to trace request and response:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpRequest;
import org.springframework.http.client.ClientHttpRequestExecution;
import org.springframework.http.client.ClientHttpRequestInterceptor;
import org.springframework.http.client.ClientHttpResponse;
public class LoggingRequestInterceptor implements ClientHttpRequestInterceptor {
final static Logger log = LoggerFactory.getLogger(LoggingRequestInterceptor.class);
@Override
public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution) throws IOException {
traceRequest(request, body);
ClientHttpResponse response = execution.execute(request, body);
traceResponse(response);
return response;
}
private void traceRequest(HttpRequest request, byte[] body) throws IOException {
log.info("===========================request begin================================================");
log.debug("URI : {}", request.getURI());
log.debug("Method : {}", request.getMethod());
log.debug("Headers : {}", request.getHeaders() );
log.debug("Request body: {}", new String(body, "UTF-8"));
log.info("==========================request end================================================");
}
private void traceResponse(ClientHttpResponse response) throws IOException {
StringBuilder inputStringBuilder = new StringBuilder();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(response.getBody(), "UTF-8"));
String line = bufferedReader.readLine();
while (line != null) {
inputStringBuilder.append(line);
inputStringBuilder.append('\n');
line = bufferedReader.readLine();
}
log.info("============================response begin==========================================");
log.debug("Status code : {}", response.getStatusCode());
log.debug("Status text : {}", response.getStatusText());
log.debug("Headers : {}", response.getHeaders());
log.debug("Response body: {}", inputStringBuilder.toString());
log.info("=======================response end=================================================");
}
}
Then instantiate RestTemplate using a BufferingClientHttpRequestFactory and the LoggingRequestInterceptor:
RestTemplate restTemplate = new RestTemplate(new BufferingClientHttpRequestFactory(new SimpleClientHttpRequestFactory()));
List<ClientHttpRequestInterceptor> interceptors = new ArrayList<>();
interceptors.add(new LoggingRequestInterceptor());
restTemplate.setInterceptors(interceptors);
The BufferingClientHttpRequestFactory is required as we want to use the response body both in the interceptor and for the initial calling code. The default implementation allows to read the response body only once.
to modify more css property values, you may use css object. such as:
hilight_css = {"border-bottom-color":"red",
"background-color":"#000"};
$(".msg").css(hilight_css);
but if the modification code is bloated. you should consider the approach March suggested. do it this way:
first, in your css file:
.hilight { border-bottom-color:red; background-color:#000; }
.msg { /* something to make it notifiable */ }
second, in your js code:
$(".msg").addClass("hilight");
// to bring message block to normal
$(".hilight").removeClass("hilight");
if ie 6 is not an issue, you can chain these classes to have more specific selectors.
Due to the bugs found by JasperV — good points! — I have rewritten my old code. I guess I only ever used this for positive values with two decimal places.
Depending on what you are trying to achieve, you may want rounding or not, so here are two versions split across that divide.
I've introduced the toFixed() method as it better handles rounding to specific decimal places accurately and is well support. It does slow things down however.
This version still detaches the decimal, but using a different method than before. The w|0 part removes the decimal. For more information on that, this is a good answer. This then leaves the remaining integer, stores it in k and then subtracts it again from the original number, leaving the decimal by itself.
Also, if we're to take negative numbers into account, we need to while loop (skipping three digits) until we hit b. This has been calculated to be 1 when dealing with negative numbers to avoid putting something like -,100.00
The rest of the loop is the same as before.
function formatThousandsWithRounding(n, dp){
var w = n.toFixed(dp), k = w|0, b = n < 0 ? 1 : 0,
u = Math.abs(w-k), d = (''+u.toFixed(dp)).substr(2, dp),
s = ''+k, i = s.length, r = '';
while ( (i-=3) > b ) { r = ',' + s.substr(i, 3) + r; }
return s.substr(0, i + 3) + r + (d ? '.'+d: '');
};
In the snippet below you can edit the numbers to test yourself.
function formatThousandsWithRounding(n, dp){_x000D_
var w = n.toFixed(dp), k = w|0, b = n < 0 ? 1 : 0,_x000D_

});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input id="dp" type="range" min="0" max="5" step="1" value="2" title="number of decimal places?" />This takes a different route and attempts to avoid mathematical calculation (as this can introduce rounding, or rounding errors). If you don't want rounding, then you are only dealing with things as a string i.e. 1000.999 converted to two decimal places will only ever be 1000.99 and not 1001.00.
This method avoids using .split() and RegExp() however, both of which are very slow in comparison. And whilst I learned something new from Michael's answer about toLocaleString, I also was surprised to learn that it is — by quite a way — the slowest method out of them all (at least in Firefox and Chrome; Mac OSX).
Using lastIndexOf() we find the possibly existent decimal point, and from there everything else is pretty much the same. Save for the padding with extra 0s where needed. This code is limited to 5 decimal places. Out of my test this was the faster method.
var formatThousandsNoRounding = function(n, dp){
var e = '', s = e+n, l = s.length, b = n < 0 ? 1 : 0,

r = e, d = s.substr(j+1, dp);
while ( (j-=3) > b ) { r = ',' + s.substr(j, 3) + r; }
return s.substr(0, j + 3) + r +
(dp ? '.' + d + ( d.length < dp ?

<input id="dp" type="range" min="0" max="5" step="1" value="2" title="number of decimal places?" />I'll update with an in-page snippet demo shortly, but for now here is a fiddle:
https://jsfiddle.net/bv2ort0a/2/
Why use RegExp for this? — don't use a hammer when a toothpick will do i.e. use string manipulation:
var formatThousands = function(n, dp){
var s = ''+(Math.floor(n)), d = n % 1, i = s.length, r = '';
while ( (i -= 3) > 0 ) { r = ',' + s.substr(i, 3) + r; }
return s.substr(0, i + 3) + r +
(d ? '.' + Math.round(d * Math.pow(10, dp || 2)) : '');
};
formatThousands( 1000000.42 );
First strip off decimal:
s = '1000000', d = ~ 0.42
Work backwards from the end of the string:
',' + '000'
',' + '000' + ',000'
Finalise by adding the leftover prefix and the decimal suffix (with rounding to dp no. decimal points):
'1' + ',000,000' + '.42'
Try this:
dataframe[column].value_counts().index.tolist()
['apple', 'sausage', 'banana', 'cheese']
Implement in this way
String i="hi";
Intent i = new Intent(this, ActivityTwo.class);
//Create the bundle
Bundle b = new Bundle();
//Add your data to bundle
b.putString(“stuff”, i);
i.putExtras(b);
startActivity(i);
Begin that second activity, inside this class to utilize the Bundle values use this code
Bundle bundle = getIntent().getExtras();
String text= bundle.getString("stuff");
<Snippet name="abc">
name is an attribute, not an element. That's why it's failing. Look into using SetAttribute on the <Snippet> element.
root.SetAttribute("name", "name goes here");
is the code you need with what you have.
A little late, but I use a _is_running variable to tell the thread when I want to close. It's easy to use, just implement a stop() inside your thread class.
def stop(self):
self._is_running = False
And in run() just loop on while(self._is_running)
my jQuery powered solution is below :)
Text Element:
<asp:TextBox ID="txtTextBox" ClientIDMode="Static" onkeypress="return EnterEvent(event);" runat="server"></asp:TextBox>
<asp:Button ID="btnSubmitButton" ClientIDMode="Static" OnClick="btnSubmitButton_Click" runat="server" Text="Submit Form" />
Javascript behind:
<script type="text/javascript" language="javascript">
function fnCheckValue() {
var myVal = $("#txtTextBox").val();
if (myVal == "") {
alert("Blank message");
return false;
}
else {
return true;
}
}
function EnterEvent(e) {
if (e.keyCode == 13) {
if (fnCheckValue()) {
$("#btnSubmitButton").trigger("click");
} else {
return false;
}
}
}
$("#btnSubmitButton").click(function () {
return fnCheckValue();
});
</script>
You can use Task.WhenAll as mentioned, or Task.WaitAll, depending on whether you want the thread to wait. Take a look at the link for an explanation of both.
$_REQUEST, by default, contains the contents of $_GET, $_POST and $_COOKIE.
But it's only a default, which depends on variables_order ; and not sure you want to work with cookies.
If I had to choose, I would probably not use $_REQUEST, and I would choose $_GET or $_POST -- depending on what my application should do (i.e. one or the other, but not both) : generally speaking :
$_GET when someone is requesting data from your application.$_POST when someone is pushing (inserting or updating ; or deleting) data to your application.Either way, there will not be much of a difference about performances : the difference will be negligible, compared to what the rest of your script will do.
The answer is no.
.class {
background-color: none; /* do not do this */
}
.class {
background-color: transparent;
}
background-color: transparent accomplishes the same thing what you wanted to do with background-color: none.
You shouldn't raise the warning, you should be using warnings module. By raising it you're generating error, rather than warning.
This works well for me:
CREATE FUNCTION [dbo].[StripNonNumerics]
(
@Temp varchar(255)
)
RETURNS varchar(255)
AS
Begin
Declare @KeepValues as varchar(50)
Set @KeepValues = '%[^0-9]%'
While PatIndex(@KeepValues, @Temp) > 0
Set @Temp = Stuff(@Temp, PatIndex(@KeepValues, @Temp), 1, '')
Return @Temp
End
Then call the function like so to see the original something next to the sanitized something:
SELECT Something, dbo.StripNonNumerics(Something) FROM TableA
If you want to split the string, it's best to use:
$array = str_split($string);
When you have delimiter, which separates the string, you can try,
explode('' ,$string);
Where you can pass the delimiter in the first variable inside the explode such as:
explode(',',$string);
I think to force StringLenght to 191 is a really bad idea. So I investigate to understand what is going on.
I noticed that this message error :
SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes
Started to show up after I updated my MySQL version. So I've checked the tables with PHPMyAdmin and I've noticed that all the new tables created were with the collation utf8mb4_unicode_ci instead of utf8_unicode_ci for the old ones.
In my doctrine config file, I noticed that charset was set to utf8mb4, but all my previous tables were created in utf8, so I guess this is some update magic that it start to work on utf8mb4.
Now the easy fix is to change the line charset in your ORM config file. Then to drop the tables using utf8mb4_unicode_ci if you are in dev mode or fixe the charset if you can't drop them.
For Symfony 4
change charset: utf8mb4 to charset: utf8 in config/packages/doctrine.yaml
Now my doctrine migrations are working again just fine.
I've just come across this, and thought I'd add my thoughts. As others have suggested, I'd recommend manually adding IDs, but if you really want something close to what you've described, you could use this:
var objectId = (function () {
var allObjects = [];
var f = function(obj) {
if (allObjects.indexOf(obj) === -1) {
allObjects.push(obj);
}
return allObjects.indexOf(obj);
}
f.clear = function() {
allObjects = [];
};
return f;
})();
You can get any object's ID by calling objectId(obj). Then if you want the id to be a property of the object, you can either extend the prototype:
Object.prototype.id = function () {
return objectId(this);
}
or you can manually add an ID to each object by adding a similar function as a method.
The major caveat is that this will prevent the garbage collector from destroying objects when they drop out of scope... they will never drop out of the scope of the allObjects array, so you might find memory leaks are an issue. If your set on using this method, you should do so for debugging purpose only. When needed, you can do objectId.clear() to clear the allObjects and let the GC do its job (but from that point the object ids will all be reset).
Like so
DECLARE @t INT=1
SELECT CASE
WHEN @t>0 THEN
CASE
WHEN @t=1 THEN 'one'
ELSE 'not one'
END
ELSE 'less than one'
END
EDIT: After looking more at the question, I think the best option is to create a function that calculates the value. That way, if you end up having multiple places where the calculation needs done, you only have one point to maintain the logic.
In .Net 2.0 I`m pretty sure about this solution:
public IEnumerable<T> Distinct<T>(IEnumerable<T> source)
{
List<T> uniques = new List<T>();
foreach (T item in source)
{
if (!uniques.Contains(item)) uniques.Add(item);
}
return uniques;
}
I recently created this Pagination component that implements paging logic like Google's search results:
import React, { PropTypes } from 'react';
const propTypes = {
items: PropTypes.array.isRequired,
onChangePage: PropTypes.func.isRequired,
initialPage: PropTypes.number
}
const defaultProps = {
initialPage: 1
}
class Pagination extends React.Component {
constructor(props) {
super(props);
this.state = { pager: {} };
}
componentWillMount() {
this.setPage(this.props.initialPage);
}
setPage(page) {
var items = this.props.items;
var pager = this.state.pager;
if (page < 1 || page > pager.totalPages) {
return;
}
// get new pager object for specified page
pager = this.getPager(items.length, page);
// get new page of items from items array
var pageOfItems = items.slice(pager.startIndex, pager.endIndex + 1);
// update state
this.setState({ pager: pager });
// call change page function in parent component
this.props.onChangePage(pageOfItems);
}
getPager(totalItems, currentPage, pageSize) {
// default to first page
currentPage = currentPage || 1;
// default page size is 10
pageSize = pageSize || 10;
// calculate total pages
var totalPages = Math.ceil(totalItems / pageSize);
var startPage, endPage;
if (totalPages <= 10) {
// less than 10 total pages so show all
startPage = 1;
endPage = totalPages;
} else {
// more than 10 total pages so calculate start and end pages
if (currentPage <= 6) {
startPage = 1;
endPage = 10;
} else if (currentPage + 4 >= totalPages) {
startPage = totalPages - 9;
endPage = totalPages;
} else {
startPage = currentPage - 5;
endPage = currentPage + 4;
}
}
// calculate start and end item indexes
var startIndex = (currentPage - 1) * pageSize;
var endIndex = Math.min(startIndex + pageSize - 1, totalItems - 1);
// create an array of pages to ng-repeat in the pager control
var pages = _.range(startPage, endPage + 1);
// return object with all pager properties required by the view
return {
totalItems: totalItems,
currentPage: currentPage,
pageSize: pageSize,
totalPages: totalPages,
startPage: startPage,
endPage: endPage,
startIndex: startIndex,
endIndex: endIndex,
pages: pages
};
}
render() {
var pager = this.state.pager;
return (
<ul className="pagination">
<li className={pager.currentPage === 1 ? 'disabled' : ''}>
<a onClick={() => this.setPage(1)}>First</a>
</li>
<li className={pager.currentPage === 1 ? 'disabled' : ''}>
<a onClick={() => this.setPage(pager.currentPage - 1)}>Previous</a>
</li>
{pager.pages.map((page, index) =>
<li key={index} className={pager.currentPage === page ? 'active' : ''}>
<a onClick={() => this.setPage(page)}>{page}</a>
</li>
)}
<li className={pager.currentPage === pager.totalPages ? 'disabled' : ''}>
<a onClick={() => this.setPage(pager.currentPage + 1)}>Next</a>
</li>
<li className={pager.currentPage === pager.totalPages ? 'disabled' : ''}>
<a onClick={() => this.setPage(pager.totalPages)}>Last</a>
</li>
</ul>
);
}
}
Pagination.propTypes = propTypes;
Pagination.defaultProps
export default Pagination;
And here's an example App component that uses the Pagination component to paginate a list of 150 example items:
import React from 'react';
import Pagination from './Pagination';
class App extends React.Component {
constructor() {
super();
// an example array of items to be paged
var exampleItems = _.range(1, 151).map(i => { return { id: i, name: 'Item ' + i }; });
this.state = {
exampleItems: exampleItems,
pageOfItems: []
};
// bind function in constructor instead of render (https://github.com/yannickcr/eslint-plugin-react/blob/master/docs/rules/jsx-no-bind.md)
this.onChangePage = this.onChangePage.bind(this);
}
onChangePage(pageOfItems) {
// update state with new page of items
this.setState({ pageOfItems: pageOfItems });
}
render() {
return (
<div>
<div className="container">
<div className="text-center">
<h1>React - Pagination Example with logic like Google</h1>
{this.state.pageOfItems.map(item =>
<div key={item.id}>{item.name}</div>
)}
<Pagination items={this.state.exampleItems} onChangePage={this.onChangePage} />
</div>
</div>
<hr />
<div className="credits text-center">
<p>
<a href="http://jasonwatmore.com" target="_top">JasonWatmore.com</a>
</p>
</div>
</div>
);
}
}
export default App;

Pscp.exe is painfully slow.
Uploading files using WinSCP is like 10 times faster.
So, to do that from command line, first you got to add the winscp.com file to your %PATH%. It's not a top-level domain, but an executable .com file, which is located in your WinSCP installation directory.
Then just issue a simple command and your file will be uploaded much faster putty ever could:
WinSCP.com /command "open sftp://username:[email protected]:22" "put your_large_file.zip /var/www/somedirectory/" "exit"
And make sure your check the synchronize folders feature, which is basically what rsync does, so you won't ever want to use pscp.exe again.
WinSCP.com /command "help synchronize"
It's the new feature in C# 6 called Interpolated Strings.
The easiest way to understand it is: an interpolated string expression creates a string by replacing the contained expressions with the ToString representations of the expressions' results.
For more details about this, please take a look at MSDN.
Now, think a little bit more about it. Why this feature is great?
For example, you have class Point:
public class Point
{
public int X { get; set; }
public int Y { get; set; }
}
Create 2 instances:
var p1 = new Point { X = 5, Y = 10 };
var p2 = new Point { X = 7, Y = 3 };
Now, you want to output it to the screen. The 2 ways that you usually use:
Console.WriteLine("The area of interest is bounded by (" + p1.X + "," + p1.Y + ") and (" + p2.X + "," + p2.Y + ")");
As you can see, concatenating string like this makes the code hard to read and error-prone. You may use string.Format() to make it nicer:
Console.WriteLine(string.Format("The area of interest is bounded by({0},{1}) and ({2},{3})", p1.X, p1.Y, p2.X, p2.Y));
This creates a new problem:
For those reasons, we should use new feature:
Console.WriteLine($"The area of interest is bounded by ({p1.X},{p1.Y}) and ({p2.X},{p2.Y})");
The compiler now maintains the placeholders for you so you don’t have to worry about indexing the right argument because you simply place it right there in the string.
For the full post, please read this blog.
The easiest way to do is so...
You set the name and value.
<input type="checkbox" name="selectedProducts" value="@item.ProductId" />@item.Name
Then on submitting grab the values of checkboxes and save in an int array. then the appropriate LinQ Function. That's it..
[HttpPost]
public ActionResult Checkbox(int[] selectedObjects)
{
var selected = from x in selectedObjects
from y in db
where y.ObjectId == x
select y;
return View(selected);
}
It is very straight forward
HTML
<input type="text" placeholder="some text" />
<input type="button" value="button" class="button"/>
<button class="button">Another button</button>
jQuery
$(document).ready(function(){
$('.button').css( 'cursor', 'pointer' );
// for old IE browsers
$('.button').css( 'cursor', 'hand' );
});
I think --include is used to include a subset of files that are otherwise excluded by --exclude, rather than including only those files.
In other words: you have to think about include meaning don't exclude.
Try instead:
rsync -zarv --include "*/" --exclude="*" --include="*.sh" "$from" "$to"
For rsync version 3.0.6 or higher, the order needs to be modified as follows (see comments):
rsync -zarv --include="*/" --include="*.sh" --exclude="*" "$from" "$to"
Adding the -m flag will avoid creating empty directory structures in the destination. Tested in version 3.1.2.
So if we only want *.sh files we have to exclude all files --exclude="*", include all directories --include="*/" and include all *.sh files --include="*.sh".
You can find some good examples in the section Include/Exclude Pattern Rules of the man page
You can reference Microsoft.VisualBasic.dll.
Then using the code below.
Microsoft.VisualBasic.Interaction.InputBox("Question?","Title","Default Text");
Alternatively, by adding a using directive allowing for a shorter syntax in your code (which I'd personally prefer).
using Microsoft.VisualBasic;
...
Interaction.InputBox("Question?","Title","Default Text");
Or you can do what Pranay Rana suggests, that's what I would've done too...
I had the same problem and solved it adding "es5" library to tsconfig.json like this:
{
"compilerOptions": {
"target": "es5", //defines what sort of code ts generates, es5 because it's what most browsers currently UNDERSTANDS.
"module": "commonjs",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true, //for angular to be able to use metadata we specify in our components.
"experimentalDecorators": true, //angular needs decorators like @Component, @Injectable, etc.
"removeComments": false,
"noImplicitAny": false,
"lib": [
"es2016",
"dom",
"es5"
]
}
}
var wordCount =
from word in words
group word by word into g
select new { g.Key, Count = g.Count() };
This is taken from one of the examples in the linqpad
I found an answer in the above link http://php.net/manual/en/function.mysql-insert-id.php
The answer is:
mysql_query("INSERT INTO tablename (columnname) values ('$value')");
echo $Id=mysql_insert_id();
I think you are looking for below code changes:
<select name="course">
<option value="0">Please Select Option</option>
<option value="PHP" <?php if($options=="PHP") echo 'selected="selected"'; ?> >PHP</option>
<option value="ASP" <?php if($options=="ASP") echo 'selected="selected"'; ?> >ASP</option>
</select>
Slight update to cumul's solution.
The function upperFirstAll doesn't work properly if there is more than one space between words. Replace the regular expression for this one to solve it:
$(this).val(txt.toLowerCase().replace(/^(.)|(\s|\-)+(.)/g,
List<string> myList = new List<string>();
IEnumerable<string> myEnumerable = myList;
List<string> listAgain = myEnumerable.ToList();
Use DATESTR
>> datestr(40189)
ans =
12-Jan-0110
Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM
>> datenum(2010,1,11)
ans =
734149
>> datenum(2010,1,11)-40189
ans =
693960
>> datestr(40189+693960)
ans =
11-Jan-2010
In other words, to convert any serial Excel date, call
datestr(excelSerialDate + 693960)
EDIT
To get the date in mm/dd/yyyy format, call datestr with the specified format
excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010
Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things
excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010

When used in a SBT project the tasks/settings may show different outputs.
To add to Kevin's answer, I find that in practice nearly all of your non-trivial Spring MVC applications will require an application context (as opposed to only the spring MVC dispatcher servlet context). It is in the application context that you should configure all non-web related concerns such as:
To make this a bit more concrete, here's an example of the Spring configuration I've used when setting up a modern (Spring version 4.1.2) Spring MVC application. Personally, I prefer to still use a WEB-INF/web.xml file but that's really the only xml configuration in sight.

As you can see, the web configuration is only a small part of the overall spring web application configuration. Most web applications I've worked with have many concerns that lie outside of the dispatcher servlet configuration that require a full-blown application context bootstrapped via the org.springframework.web.context.ContextLoaderListener in the web.xml.
Just try this in Javascript:
$previous = "javascript:history.go(-1)";
Or you can try it in PHP:
if(isset($_SERVER['HTTP_REFERER'])) {
$previous = $_SERVER['HTTP_REFERER'];
}
In Swift 3.0
let screenSize = UIScreen.main.bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height
In older swift: Do something like this:
let screenSize: CGRect = UIScreen.mainScreen().bounds
then you can access the width and height like this:
let screenWidth = screenSize.width
let screenHeight = screenSize.height
if you want 75% of your screen's width you can go:
let screenWidth = screenSize.width * 0.75
Swift 4.0
// Screen width.
public var screenWidth: CGFloat {
return UIScreen.main.bounds.width
}
// Screen height.
public var screenHeight: CGFloat {
return UIScreen.main.bounds.height
}
In Swift 5.0
let screenSize: CGRect = UIScreen.main.bounds
If you want to use less code, you can also use the norm in the stats package (the 'F' stands for Forbenius, which is the Euclidean norm):
norm(matrix(x1-x2), 'F')
While this may look a bit neater, it's not faster. Indeed, a quick test on very large vectors shows little difference, though so12311's method is slightly faster. We first define:
set.seed(1234)
x1 <- rnorm(300000000)
x2 <- rnorm(300000000)
Then testing for time yields the following:
> system.time(a<-sqrt(sum((x1-x2)^2)))
user system elapsed
1.02 0.12 1.18
> system.time(b<-norm(matrix(x1-x2), 'F'))
user system elapsed
0.97 0.33 1.31
If you're sure it'll parse correctly, use
int.Parse(string)
If you're not, use
int i;
bool success = int.TryParse(string, out i);
Caution! In the case below, i will equal 0, not 10 after the TryParse.
int i = 10;
bool failure = int.TryParse("asdf", out i);
This is because TryParse uses an out parameter, not a ref parameter.
Also make sure the page is valid. You can check this in the browsers developer tools (F12)
In the Console tab select the correct Target/Frame and check for the [Page_IsValid] property
If the page is not valid the form will not submit and therefore not fire the event.
git checkout -f
must work, if your previous state is clean.
BoltClock's answer is correct. The only thing I want to append is that if you want to only select the pseudo element, put in a span.
For example:
<li><span data-icon='u'></span> List Element </li>
instead of:
<li> data-icon='u' List Element</li>
This way you can simply say
ul [data-icon]:hover::before {color: #f7f7f7;}
which will only highlight the pseudo element, not the entire li element

Update
I've written a cross-browser range and selection library called Rangy that incorporates an improved version of the code I posted below. You can use the selection save and restore module for this particular question, although I'd be tempted to use something like @Nico Burns's answer if you're not doing anything else with selections in your project and don't need the bulk of a library.
Previous answer
You can use IERange (http://code.google.com/p/ierange/) to convert IE's TextRange into something like a DOM Range and use it in conjunction with something like eyelidlessness's starting point. Personally I would only use the algorithms from IERange that do the Range <-> TextRange conversions rather than use the whole thing. And IE's selection object doesn't have the focusNode and anchorNode properties but you should be able to just use the Range/TextRange obtained from the selection instead.
I might put something together to do this, will post back here if and when I do.
EDIT:
I've created a demo of a script that does this. It works in everything I've tried it in so far except for a bug in Opera 9, which I haven't had time to look into yet. Browsers it works in are IE 5.5, 6 and 7, Chrome 2, Firefox 2, 3 and 3.5, and Safari 4, all on Windows.
http://www.timdown.co.uk/code/selections/
Note that selections may be made backwards in browsers so that the focus node is at the start of the selection and hitting the right or left cursor key will move the caret to a position relative to the start of the selection. I don't think it is possible to replicate this when restoring a selection, so the focus node is always at the end of the selection.
I will write this up fully at some point soon.
I use this often in my projects. This solution works with scrollviews, tableviews or collectionviews and it’s easy to setup. It also automatically hooks up “Next” buttons on the keyboard to switch through the text fields.

A simple, fast way to get the content by id :
echo get_post_field('post_content', $id);
And if you want to get the content formatted :
echo apply_filters('the_content', get_post_field('post_content', $id));
Works with pages, posts & custom posts.
Just store the index generated in a variable, and then access the array using this varaible:
int idx = new Random().nextInt(fruits.length);
String random = (fruits[idx]);
P.S. I usually don't like generating new Random object per randoization - I prefer using a single Random in the program - and re-use it. It allows me to easily reproduce a problematic sequence if I later find any bug in the program.
According to this approach, I will have some variable Random r somewhere, and I will just use:
int idx = r.nextInt(fruits.length)
However, your approach is OK as well, but you might have hard time reproducing a specific sequence if you need to later on.
If you are using Spring you can use StringUtils.join() method which also allows you to specify prefix and suffix.
String s = StringUtils.collectionToDelimitedString(fieldRoles.keySet(),
"\n", "<value>", "</value>");
Here's the simple, built-in way:
<span title="My tip">text</span>
That gives you plain text tooltips. If you want rich tooltips, with formatted HTML in them, you'll need to use a library to do that. Fortunately there are loads of those.
You'll need to join twice:
SELECT home.*, away.*, g.network, g.date_start
FROM game AS g
INNER JOIN team AS home
ON home.importid = g.home
INNER JOIN team AS away
ON away.importid = g.away
ORDER BY g.date_start DESC
LIMIT 7
$(this) is a jQuery object that is wrapping the DOM element this and jQuery objects don't have id properties. You probably want just this.id to get the id attribute of the clicked element.
I would simply do this, which literally follows what your desired logic was:
df.groupby(['org']).mean().groupby(['cluster']).mean()

If you don't care about formatting and you just need some quick date, you can use this:
import time
print(time.ctime())
View Custmv;
private void initViews() {
inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
Custmv = inflater.inflate(R.layout.id_number_edit_text_custom, this, true);
editText = (EditText) findViewById(R.id.id_number_custom);
loadButton = (ImageButton) findViewById(R.id.load_data_button);
loadButton.setVisibility(RelativeLayout.INVISIBLE);
loadData();
}
private void loadData(){
loadButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
EditText firstName = (EditText) Custmv.getParent().findViewById(R.id.display_name);
firstName.setText("Some Text");
}
});
}
try like this.
A little late to this party - but this also works well:
CREATE VIEW [ABC].[View_SomeDataUniqueKey]
AS
SELECT
CAST(CONCAT(CAST([ID] AS VARCHAR(4)),
CAST(ROW_NUMBER() OVER(ORDER BY [ID] ASC) as VARCHAR(4))
) AS int) AS [UniqueId]
,[ID]
FROM SOME_TABLE JOIN SOME_OTHER_TABLE
GO
In my case the join resulted in [ID] - the primary key being repeated up to 5 times (associated different unique data) The nice trick with this is that the original ID can be determined from each UniqueID effectively [ID]+RowNumber() = 11, 12, 13, 14, 21, 22, 23, 24 etc. If you add RowNumber() and [ID] back into the view - you can easily determine your original key from the data. But - this is not something that should be committed to a table because I am fairly sure that the RowNumber() of a view will never be reliably the same as the underlying data alters, even with the OVER(ORDER BY [ID] ASC) to try and help it.
Example output ( Select UniqueId, ID, ROWNR, Name from [REF].[View_Systems] ) :
UniqueId ID ROWNR Name

,TABA.[ID]
,ROW_NUMBER() OVER(ORDER BY TABA.[ID] ASC) AS ROWNR

FROM [Ref].[Table1] TABA LEFT JOIN [Ref].[Table2] TABB ON TABA.[ID] = TABB.[ID]

Adding lots of load balancers creates extra overhead and latency and that is the drawback for scaling out horizontally in nosql databases. It is like the question why people say RPC is not recommended since it is not robust.
I think in a real system we should use both sql and nosql databases to utilize both multicore and cloud computing capabilities of today's systems.
On the other hand, complex transactional queries has high performance if sql databases such as oracle being used. NoSql could be used for bigdata and horizontal scalability by sharding.
To find first element in a sequence seq that matches a predicate:
next(x for x in seq if predicate(x))
Or (itertools.ifilter on Python 2):
next(filter(predicate, seq))
It raises StopIteration if there is none.
To return None if there is no such element:
next((x for x in seq if predicate(x)), None)
Or:
next(filter(predicate, seq), None)
You might want to take a look at Maven (http://maven.apache.org). You can use it either as the main build process for your application, or just to perform certain tasks through the Edit Configurations dialog. The process of creating a JAR of a module within Maven is fairly trivial, if you want it to include all the dependencies in a self-executable JAR that is trivial as well.
If you've never used Maven before then you want to read Better Builds With Maven.
I guess you already have the process object of the running process (e.g. by GetProcessesByName()). You can then get the executable file name by using
Process p;
string filename = p.MainModule.FileName;
No, try using a strongly typed List instead.
For example:
Instead of using
int[] myArray = new int[2];
myArray[0] = 1;
myArray[1] = 2;
You could do this:
List<int> myList = new List<int>();
myList.Add(1);
myList.Add(2);
Lists use arrays to store the data so you get the speed benefit of arrays with the convenience of a LinkedList by being able to add and remove items without worrying about having to manually change its size.
This doesn't mean an array's size (in this instance, a List) isn't changed though - hence the emphasis on the word manually.
As soon as your array hits its predefined size, the JIT will allocate a new array on the heap that is twice the size and copy your existing array across.
The problem is that tick() needs to know the definition of tile_tree_apple, but all it has is a forward declaration of it. You should separate the declarations and definitions like so:
tile_tree.h
#ifndef TILE_TREE_H
#define TILE_TREE_H
#include "tile.h"
class tile_tree : public tile
{
public:
tile onDestroy();
tile tick();
void onCreate();
};
#endif
tile_tree.cpp:
tile tile_tree::onDestroy() {
return *new tile_grass;
}
tile tile_tree::tick() {
if (rand() % 20 == 0)
return *new tile_tree_apple;
}
void tile_tree::onCreate() {
health = rand() % 5 + 4;
type = TILET_TREE;
}
Except you have a major problem: you’re allocating memory (with new), then copying the allocated object and returning the copy. This is called a memory leak, because there’s no way for your program to free the memory it uses. Not only that, but you’re copying a tile_tree into a tile, which discards the information that makes a tile_tree different from a tile; this is called slicing.
What you want is to return a pointer to a new tile, and make sure you call delete at some point to free the memory:
tile* tile_tree::tick() {
if (rand() % 20 == 0)
return new tile_tree_apple;
}
Even better would be to return a smart pointer that will handle the memory management for you:
#include <memory>
std::shared_ptr<tile> tile_tree::tick() {
if (rand() % 20 == 0)
return std::make_shared<tile_tree_apple>();
}
Sounds to me like at least one of those tables has defined UserID as a uniqueidentifier, not an int. Did you check the data in each table? What does SELECT TOP 1 UserID FROM each table yield? An int or a GUID?
EDIT
I think you have built a procedure based on all tables that contain a column named UserID. I think you should not have included the aspnet_Membership table in your script, since it's not really one of "your" tables.
If you meant to design your tables around the aspnet_Membership database, then why are the rest of the columns int when that table clearly uses a uniqueidentifier for the UserID column?

You can use the DataGridView refresh method. But... in a lot of cases you have to refresh the DataGridView from methods running on a different thread than the one where the DataGridView is running. In order to do that you should implement the following method and call it rather than directly typing DataGridView.Refresh():
private void RefreshGridView()
{
if (dataGridView1.InvokeRequired)
{
dataGridView1.Invoke((MethodInvoker)delegate ()
{
RefreshGridView();
});
}
else
dataGridView1.Refresh();
}
You are not adding the object to the session, instead you are adding it to the request.
What you need is:
HttpSession session = request.getSession();
session.setAttribute("MySessionVariable", param);
In Servlets you have 4 scopes where you can store data.
Make sure you understand these. For more look here
Inside the fragment's onCreate method add the following:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
OnBackPressedCallback callback = new OnBackPressedCallback(true) {
@Override
public void handleOnBackPressed() {
//Handle the back pressed
}
};
requireActivity().getOnBackPressedDispatcher().addCallback(this, callback);
}
It works perfectly.
Add to use this with config file like Plist, you need to use CDATA to write the multilined title, like this:
<string><![CDATA[Line1
Line2]]></string>
you can use valign="top" on the td tag it is working perfectly for me.
I typically see a 30% speed improvement for compute-intensive code on x86-64 compared to x86. This is most likely due to the fact that we have 16 x 64 bit general purpose registers and 16 x SSE registers instead of 8 x 32 bit general purpose registers and 8 x SSE registers. This is with the Intel ICC compiler (11.1) on an x86-64 Linux - results with other compilers (e.g. gcc), or with other operating systems (e.g. Windows), may be different of course.
concept = concept.encode('ascii', 'ignore')
concept = MySQLdb.escape_string(concept.decode('latin1').encode('utf8').rstrip())

None of the above worked for me in Sublime Text 2 on Windows.
I did this:
By selecting before hitting ctrl+H it uses that as the character to be replaced.
HTML 4 does not make it explicit. The current HTML5 working draft specifies that the first submit button must be the default:
A
formelement's default button is the first submit button in tree order whose form owner is thatformelement.If the user agent supports letting the user submit a form implicitly (for example, on some platforms hitting the "enter" key while a text field is focused implicitly submits the form), then doing so for a form whose default button has a defined activation behavior must cause the user agent to run synthetic click activation steps on that default button.
We don't stop or kill a thread rather we do Thread.currentThread().isInterrupted().
public class Task1 implements Runnable {
public void run() {
while (!Thread.currentThread().isInterrupted()) {
................
................
................
................
}
}
}
in main we will do like this:
Thread t1 = new Thread(new Task1());
t1.start();
t1.interrupt();
To get the number of rows in a dataframe use:
df.shape[0]
(and df.shape[1] to get the number of columns).
As an alternative you can use
len(df)
or
len(df.index)
(and len(df.columns) for the columns)
shape is more versatile and more convenient than len(), especially for interactive work (just needs to be added at the end), but len is a bit faster (see also this answer).
To avoid: count() because it returns the number of non-NA/null observations over requested axis
len(df.index) is faster
import pandas as pd
import numpy as np
df = pd.DataFrame(np.arange(24).reshape(8, 3),columns=['A', 'B', 'C'])
df['A'][5]=np.nan
df
# Out:
# A B C
# 0 0 1 2
# 1 3 4 5
# 2 6 7 8
# 3 9 10 11
# 4 12 13 14
# 5 NaN 16 17
# 6 18 19 20
# 7 21 22 23
%timeit df.shape[0]
# 100000 loops, best of 3: 4.22 µs per loop
%timeit len(df)
# 100000 loops, best of 3: 2.26 µs per loop
%timeit len(df.index)
# 1000000 loops, best of 3: 1.46 µs per loop
df.__len__ is just a call to len(df.index)
import inspect
print(inspect.getsource(pd.DataFrame.__len__))
# Out:
# def __len__(self):
# """Returns length of info axis, but here we use the index """
# return len(self.index)
Why you should not use count()
df.count()
# Out:
# A 7
# B 8
# C 8
Using dictionaries should be right way to keep the variables and associated values, and you may use this:
dict_ = {}
for i in range(9):
dict_['string%s' % i] = 'Hello'
But if you want to add the variables to the local variables you can use:
for i in range(9):
exec('string%s = Hello' % i)
And for example if you want to assign values 0 to 8 to them, you may use:
for i in range(9):
exec('string%s = %s' % (i,i))
When using MVC, try using ViewBag. The best way to take input from textbox and displaying in View.
I use
chartRange = xlWorkSheet.Rows[1];
chartRange.Font.Bold = true;
to turn the first-row-cells-font into bold. And it works, and I am using also Excel 2007.
You can call in VBA directly
ActiveCell.Font.Bold = True
With this code I create a timestamp in the active cell, with bold font and yellow background
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
ActiveCell.Value = Now()
ActiveCell.Font.Bold = True
ActiveCell.Interior.ColorIndex = 6
End Sub
Use the following in the function you will call and it will work just fine.
[a b c] = yourfunction(optional)
%your code
a = 5;
b = 7;
c = 10;
return
end
This is a way to call the function both from another function and from the command terminal
[aa bb cc] = yourfunction(optional);
The variables aa, bb and cc now hold the return variables.
An elegant way to implement this would be to make an extension method, like this:
public static class Extensions
{
public static List<string> GetSelectedItems(this CheckBoxList cbl)
{
var result = new List<string>();
foreach (ListItem item in cbl.Items)
if (item.Selected)
result.Add(item.Value);
return result;
}
}
I can then use something like this to compose a string will all values separated by ';':
string.Join(";", cbl.GetSelectedItems());
I find this particularly useful for when you want to 'store' a function call.
For example, suppose I have some unit tests for a function 'add':
def add(a, b): return a + b
tests = { (1,4):5, (0, 0):0, (-1, 3):3 }
for test, result in tests.items():
print 'test: adding', test, '==', result, '---', add(*test) == result
There is no other way to call add, other than manually doing something like add(test[0], test[1]), which is ugly. Also, if there are a variable number of variables, the code could get pretty ugly with all the if-statements you would need.
Another place this is useful is for defining Factory objects (objects that create objects for you).
Suppose you have some class Factory, that makes Car objects and returns them.
You could make it so that myFactory.make_car('red', 'bmw', '335ix') creates Car('red', 'bmw', '335ix'), then returns it.
def make_car(*args):
return Car(*args)
This is also useful when you want to call a superclass' constructor.
As many people suggested, you could use std::make_pair.
But I would like to point out another method of doing the same:
revenue.push_back({"string",map[i].second});
push_back() accepts a single parameter, so you could use "{}" to achieve this!
Pandas will recognise a value as null if it is a np.nan object, which will print as NaN in the DataFrame. Your missing values are probably empty strings, which Pandas doesn't recognise as null. To fix this, you can convert the empty stings (or whatever is in your empty cells) to np.nan objects using replace(), and then call dropna()on your DataFrame to delete rows with null tenants.
To demonstrate, we create a DataFrame with some random values and some empty strings in a Tenants column:
>>> import pandas as pd
>>> import numpy as np
>>>
>>> df = pd.DataFrame(np.random.randn(10, 2), columns=list('AB'))
>>> df['Tenant'] = np.random.choice(['Babar', 'Rataxes', ''], 10)
>>> print df
A B Tenant
0 -0.588412 -1.179306 Babar
1 -0.008562 0.725239
2 0.282146 0.421721 Rataxes
3 0.627611 -0.661126 Babar
4 0.805304 -0.834214
5 -0.514568 1.890647 Babar
6 -1.188436 0.294792 Rataxes
7 1.471766 -0.267807 Babar
8 -1.730745 1.358165 Rataxes
9 0.066946 0.375640
Now we replace any empty strings in the Tenants column with np.nan objects, like so:
>>> df['Tenant'].replace('', np.nan, inplace=True)
>>> print df
A B Tenant
0 -0.588412 -1.179306 Babar
1 -0.008562 0.725239 NaN
2 0.282146 0.421721 Rataxes
3 0.627611 -0.661126 Babar
4 0.805304 -0.834214 NaN
5 -0.514568 1.890647 Babar
6 -1.188436 0.294792 Rataxes
7 1.471766 -0.267807 Babar
8 -1.730745 1.358165 Rataxes
9 0.066946 0.375640 NaN
Now we can drop the null values:
>>> df.dropna(subset=['Tenant'], inplace=True)
>>> print df
A B Tenant
0 -0.588412 -1.179306 Babar
2 0.282146 0.421721 Rataxes
3 0.627611 -0.661126 Babar
5 -0.514568 1.890647 Babar
6 -1.188436 0.294792 Rataxes
7 1.471766 -0.267807 Babar
8 -1.730745 1.358165 Rataxes
There is also OkHttp, which is an HTTP client that’s efficient by default:
- HTTP/2 support allows all requests to the same host to share a socket.
- Connection pooling reduces request latency (if HTTP/2 isn’t available).
- Transparent GZIP shrinks download sizes.
- Response caching avoids the network completely for repeat requests.
First create an instance of OkHttpClient:
OkHttpClient client = new OkHttpClient();
Then, prepare your GET request:
Request request = new Request.Builder()
.url(url)
.build();
finally, use OkHttpClient to send prepared Request:
Response response = client.newCall(request).execute();
For more details, you can consult the OkHttp's documentation
Below are the steps you can try it out to resolve the issue: -
parent="android:Theme.Holo.Light" instead.
parent="android:Theme.AppCompat.Light" But option 2 will require minimum sdk version 14.
Hope this will help !

Just to add - Safari 2 and earlier definitely didn't support PUT and DELETE. I get the impression 3 did, but I don't have it around to test anymore. Safari 4 definitely does support PUT and DELETE.

I mashed up a few answers.
Use an ivar that gets initialized during viewDidLoad:
UIGestureRecognizer *tapper;
- (void)viewDidLoad
{
[super viewDidLoad];
tapper = [[UITapGestureRecognizer alloc]
initWithTarget:self action:@selector(handleSingleTap:)];
tapper.cancelsTouchesInView = NO;
[self.view addGestureRecognizer:tapper];
}
Dismiss what ever is currently editing:
- (void)handleSingleTap:(UITapGestureRecognizer *) sender
{
[self.view endEditing:YES];
}
Use Jquery and wait till the source is loaded, This is how I have achieved(Used angular interval, you can use javascript setInterval method):
var addCssToIframe = function() {
if ($('#myIframe').contents().find("head") != undefined) {
$('#myIframe')
.contents()
.find("head")
.append(
'<link rel="stylesheet" href="app/css/iframe.css" type="text/css" />');
$interval.cancel(addCssInterval);
}
};
var addCssInterval = $interval(addCssToIframe, 500, 0, false);
Simple! The folder named .. is the parent folder, so you can make the path to the file you need as such
var foobar = require('../config/dev/foobar.json');
If you needed to go up two levels, you would write ../../ etc
Some more details about this in this SO answer and it's comments
For users using CoffeeScript, you can use a range comprehension:
Directive
link: (scope, element, attrs) ->
scope.range = [1..+attrs.range]
or Controller
$scope.range = [1..+$someVariable]
$scope.range = [1..5] # Or just an integer
Template
<div ng-repeat="i in range">[ the rest of your code ]</div>
The cmdlets in PowerShell are very nice and work reliably. Their object-orientedness appeals to me a lot since I'm a Java/C# developer, but it's not at all a complete set. Since it's object oriented, it's missed out on a lot of the text stream maturity of the POSIX tool set (awk and sed to name a few).
The best answer I've found to the dilemma of loving OO techniques and loving the maturity in the POSIX tools is to use both! One great aspect of PowerShell is that it does an excellent job piping objects to standard streams. PowerShell by default uses an object pipeline to transport its objects around. These aren't the standard streams (standard out, standard error, and standard in). When PowerShell needs to pass output to a standard process that doesn't have an object pipeline, it first converts the objects to a text stream. Since it does this so well, PowerShell makes an excellent place to host POSIX tools!
The best POSIX tool set is GnuWin32. It does take more than 5 seconds to install, but it's worth the trouble, and as far as I can tell, it doesn't modify your system (registry, c:\windows\* folders, etc.) except copying files to the directories you specify. This is extra nice because if you put the tools in a shared directory, many people can access them concurrently.
Download and execute the exe (it's from the SourceForge site) pointing it to a suitable directory (I'll be using C:\bin). It will create a GetGnuWin32 directory there in which you will run download.bat, then install.bat (without parameters), after which, there will be a C:\bin\GetGnuWin32\gnuwin32\bin directory that is the most useful folder that has ever existed on a Windows machine. Add that directory to your path, and you're ready to go.
I use
file_age() {
local filename=$1
echo $(( $(date +%s) - $(date -r $filename +%s) ))
}
is_stale() {
local filename=$1
local max_minutes=20
[ $(file_age $filename) -gt $(( $max_minutes*60 )) ]
}
if is_stale /my/file; then
...
fi
You can pass an instance of java.lang.Class that represents the type, i.e.
private void foo(Class cls)
Yes, you can. But if you have non-unique entries on your table, it will fail. Here is the how to add unique constraint on your table. If you're using PostgreSQL 9.x you can follow below instruction.
CREATE UNIQUE INDEX constraint_name ON table_name (columns);
The onBlur event is fired when you have moved away from an object without necessarily having changed its value.
The onChange event is only called when you have changed the value of the field and it loses focus.
You might want to take a look at quirksmode's intro to events. This is a great place to get info on what's going on in your browser when you interact with it. His book is good too.
If you do overflow:hidden then keep in mind that it will also hide the comment box that comes up in XFBML version... after user likes it. So best if you do this...
/* make the like button smaller */
.fb_edge_widget_with_comment iframe
{
width:47px !important;
}
/* but make the span that holds the comment box larger */
span.fb_edge_comment_widget.fb_iframe_widget iframe
{
width:401px !important;
}
I did the following in my lib kontraktor:
public class Actor<SELF extends Actor> {
public SELF self() { return (SELF)_self; }
}
subclassing:
public class MyHttpAppSession extends Actor<MyHttpAppSession> {
...
}
at least this works inside the current class and when having a strong typed reference. Multiple inheritance works, but gets really tricky then :)
math.fabs() always returns float, while abs() may return integer.
You could easily replace the forward slashes / with something like an underscore _ such as Wikipedia uses for spaces. Replacing special characters with underscores, etc., is common practice.
Indeed, you can leave it empty (W3 validator doesn't complain).
Taking the idea one step further: leave out the ="". The advantage of this is that the link isn't treated as an anchor to the current page.
<a href>sth</a>
You can use Spacers if all you want is a little bit of spacing between items in a row. The example below centers 2 Text widgets within a row with some spacing between them.
Spacer creates an adjustable, empty spacer that can be used to tune the spacing between widgets in a Flex container, like Row or Column.
In a row, if we want to put space between two widgets such that it occupies all remaining space.
widget = Row (
children: <Widget>[
Spacer(flex: 20),
Text(
"Item #1",
),
Spacer(), // Defaults to flex: 1
Text(
"Item #2",
),
Spacer(flex: 20),
]
);
You also can, as Fredigato said, declare a RelativeLayout in a separate Layout file. Then instantiate it using:
for(int i = 0; i < 6; i ++){
LayoutInflater inflater = (LayoutInflater)getApplicationContext().getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout row = (RelativeLayout) inflater.inflate(R.layout.table_view,null);
quizesTableLayout.addView(row,i);
}
In this approach you can easily design one custom row using XML and reuse it.
Now, to be able to change the children views in the instantiated RelativeLayout. You can call row.childAt(index).
So lets say you have a TextView in the RelativeLayout, you can use:
TextView tv = (TextView) row.childAt(0);
tv.setText("Text");
Make the image 100% bright so it is clear. And then on Img hover reduce it to whatever brightness you want.
img {_x000D_
-webkit-transition: all 1s ease;_x000D_
-moz-transition: all 1s ease;_x000D_
-o-transition: all 1s ease;_x000D_
-ms-transition: all 1s ease;_x000D_
transition: all 1s ease;_x000D_
}_x000D_
_x000D_
img:hover {_x000D_
-webkit-filter: brightness(70%);_x000D_
filter: brightness(70%);_x000D_
}<img src="http://dummyimage.com/300x150/ebebeb/000.jpg">That will do it, Hope that helps

Hope this will help some of you guys.
With Lodash, you can do:
if(_.has(req,'documents')){
if (req.documents.length)
_.forEach(req.documents, function(document){
records.push(document);
});
} else {
}
if(_.has(req,'documents')) is to check whether our request object has a property named documents and if it has that prop, the next if (req.documents.length) is to validate if it is not an empty array, so the other stuffs like forEach can be proceeded.
See:- ConnectionStrings content on this subject. There is no default command timeout property.
model.remove({title:'danish'}, function(err){
if(err) throw err;
});
XDebug changed some configuration settings.
Old settings:
xdebug.remote_enable = 1
xdebug.remote_autostart = 1
xdebug.remote_port = 9000
New settings:
xdebug.mode=debug
xdebug.start_with_request=yes
xdebug.client_port=9000
So you should paste the latter in php.ini file. More info: XDebug Changed Configuration Settings
Since the problem is the non-trivial destructor so if the destructor is removed from the std::string, it's possible to define a constexpr instance of that type. Like this
struct constexpr_str {
char const* str;
std::size_t size;
// can only construct from a char[] literal
template <std::size_t N>
constexpr constexpr_str(char const (&s)[N])
: str(s)
, size(N - 1) // not count the trailing nul
{}
};
int main()
{
constexpr constexpr_str s("constString");
// its .size is a constexpr
std::array<int, s.size> a;
return 0;
}
You can also use "or" operator,
for( int i = 0 ; i < 100 || someOtherCondition() ; i++ ) {
...
}
It is absolutely possible to install side-by-side several JRE/JDK versions. Moreover, you don't have to do anything special for that to happen, as Sun is creating a different folder for each (under Program Files).
There is no control panel to check which JRE works for each application. Basically, the JRE that will work would be the first in your PATH environment variable. You can change that, or the JAVA_HOME variable, or create specific cmd/bat files to launch the applications you desire, each with a different JRE in path.
You can do it this way to return you a list of absolute path files.
def list_files_recursive(path):
"""
Function that receives as a parameter a directory path
:return list_: File List and Its Absolute Paths
"""
import os
files = []
# r = root, d = directories, f = files
for r, d, f in os.walk(path):
for file in f:
files.append(os.path.join(r, file))
lst = [file for file in files]
return lst
if __name__ == '__main__':
result = list_files_recursive('/tmp')
print(result)
In this scenario, I prefer to create new branches for each issue. I use a prefix temp/ so I know that I can delete these branches later.
git checkout -b temp/bug1
Stage the files that fix bug1 and commit them.
git checkout -b temp/bug2
You can then cherry pick the commits from the respective branches as require and submit a pull request.
You can use "find" for remove all files in the /objects directory with 0 in size with the command:
find .git/objects/ -size 0 -delete
Backup is recommended.
I think you should be able to use a default route handler and redirect from there to a page outside the app, as detailed below:
const ROUTER_INSTANCE = new VueRouter({
mode: "history",
routes: [
{ path: "/", component: HomeComponent },
// ... other routes ...
// and finally the default route, when none of the above matches:
{ path: "*", component: PageNotFound }
]
})
In the above PageNotFound component definition, you can specify the actual redirect, that will take you out of the app entirely:
Vue.component("page-not-found", {
template: "",
created: function() {
// Redirect outside the app using plain old javascript
window.location.href = "/my-new-404-page.html";
}
}
You may do it either on created hook as shown above, or mounted hook also.
Please note:
I have not verified the above. You need to build a production version of app, ensure that the above redirect happens. You cannot test this in vue-cli as it requires server side handling.
Usually in single page apps, server sends out the same index.html along with app scripts for all route requests, especially if you have set <base href="/">. This will fail for your /404-page.html unless your server treats it as a special case and serves the static page.
Let me know if it works!
Update for Vue 3 onward:
You'll need to replace the '*' path property with '/:pathMatch(.*)*' if you're using Vue 3 as the old catch-all path of '*' is no longer supported. The route would then look something like this:
{ path: '/:pathMatch(.*)*', component: PathNotFound },
See the docs for more info on this update.

I don't believe so. Even if I'm wrong, the best you can hope for is adding them to an entire Type, never an instance of a Type.
Let me start with Integrated Security = false
false User ID and Password are specified in the connection string.
true Windows account credentials are used for authentication.
Recognized values are true, false, yes, no, and SSPI.
If User ID and Password are specified and Integrated Security is set to true, then User ID and Password will be ignored and Integrated Security will be used

Only an addition to the above responses: A possibility in such cases is that you are calling an object, that for some reason is not available to your query. For example you may subset by row names or column names, and you will receive this error message when your requested row or column is not part of the data matrix or data frame anymore. Solution: As a short version of the responses above: you need to find the last working row name or column name, and the next called object should be the one that could not be found. If you run parallel codes like "foreach", then you need to convert your code to a for loop to be able to troubleshoot it.
There's multiple ways of doing things in batch, so if escaping with a double percent %% isn't working for you, then you could try something like this:
set olddir=%CD%
cd /d "path of folder"
del "file name/ or *.txt etc..."
cd /d "%olddir%"
How this works:
set olddir=%CD% sets the variable "olddir" or any other variable name you like to the directory
your batch file was launched from.
cd /d "path of folder" changes the current directory the batch will be looking at. keep the
quotations and change path of folder to which ever path you aiming for.
del "file name/ or *.txt etc..." will delete the file in the current directory your batch is looking at, just don't add a directory path before the file name and just have the full file name or, to delete multiple files with the same extension with *.txt or whatever extension you need.
cd /d "%olddir%" takes the variable saved with your old path and goes back to the directory you started the batch with, its not important if you don't want the batch going back to its previous directory path, and like stated before the variable name can be changed to whatever you wish by changing the set olddir=%CD% line.
This does not work, because Chrome forbids any kind of inline code in extensions via Content Security Policy.
Inline JavaScript will not be executed. This restriction bans both inline
<script>blocks and inline event handlers (e.g.<button onclick="...">).
If this is indeed the problem, Chrome would produce the following error in the console:
Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'self' chrome-extension-resource:". Either the 'unsafe-inline' keyword, a hash ('sha256-...'), or a nonce ('nonce-...') is required to enable inline execution.
To access a popup's JavaScript console (which is useful for debug in general), right-click your extension's button and select "Inspect popup" from the context menu.
More information on debugging a popup is available here.
One needs to remove all inline JavaScript. There is a guide in Chrome documentation.
Suppose the original looks like:
<a onclick="handler()">Click this</a> <!-- Bad -->
One needs to remove the onclick attribute and give the element a unique id:
<a id="click-this">Click this</a> <!-- Fixed -->
And then attach the listener from a script (which must be in a .js file, suppose popup.js):
// Pure JS:
document.addEventListener('DOMContentLoaded', function() {
document.getElementById("click-this").addEventListener("click", handler);
});
// The handler also must go in a .js file
function handler() {
/* ... */
}
Note the wrapping in a DOMContentLoaded event. This ensures that the element exists at the time of execution. Now add the script tag, for instance in the <head> of the document:
<script src="popup.js"></script>
Alternative if you're using jQuery:
// jQuery
$(document).ready(function() {
$("#click-this").click(handler);
});
Q: The error mentions ways to allow inline code. I don't want to / can't change my code, how do I enable inline scripts?
A: Despite what the error says, you cannot enable inline script:
There is no mechanism for relaxing the restriction against executing inline JavaScript. In particular, setting a script policy that includes
'unsafe-inline'will have no effect.
Update: Since Chrome 46, it's possible to whitelist specific inline code blocks:
As of Chrome 46, inline scripts can be whitelisted by specifying the base64-encoded hash of the source code in the policy. This hash must be prefixed by the used hash algorithm (sha256, sha384 or sha512). See Hash usage for
<script>elements for an example.
However, I do not readily see a reason to use this, and it will not enable inline attributes like onclick="code".
I built this little function to automatically format anything into a nice currency format.
function formatDollars($dollars)
{
return "$".number_format(sprintf('%0.2f', preg_replace("/[^0-9.]/", "", $dollars)),2);
}
Edit
It was pointed out that this does not show negative values. I broke it into two lines so it's easier to edit the formatting. Wrap it in parenthesis if it's a negative value:
function formatDollars($dollars)
{
$formatted = "$" . number_format(sprintf('%0.2f', preg_replace("/[^0-9.]/", "", $dollars)), 2);
return $dollars < 0 ? "({$formatted})" : "{$formatted}";
}
<?PHP
echo "Firstline";
include('classes/connection.php');
echo "I will run if include but not on Require";
?>
A very simple Practical example with code. The first echo will be displayed. No matter you use include or require because its runs before include or required.
To check the result, In second line of a code intentionally provide the wrong path to the file or make error in file name. Thus the second echo to be displayed or not will be totally dependent on whether you use require or include.
If you use require the second echo will not execute but if you use include not matter what error comes you will see the result of second echo too.

The problem, in my case, was that some install at some point defined an environment variable http_proxy on my machine when I had no proxy.
Removing the http_proxy environment variable fixed the problem.
string = "{'server1':'value','server2':'value'}"
#Now removing { and }
s = string.replace("{" ,"")
finalstring = s.replace("}" , "")
#Splitting the string based on , we get key value pairs
list = finalstring.split(",")
dictionary ={}
for i in list:
#Get Key Value pairs separately to store in dictionary
keyvalue = i.split(":")
#Replacing the single quotes in the leading.
m= keyvalue[0].strip('\'')
m = m.replace("\"", "")
dictionary[m] = keyvalue[1].strip('"\'')
print dictionary
Please see my project of the cross-browser filter of value of the text input element on your web page using JavaScript language: Input Key Filter . You can filter the value as an integer number, a float number, or write a custom filter, such as a phone number filter. See an example of custom filter of input of an float number with decimal pointer and limitation to 2 digit after decimal pointer:

You can use ScriptEngine, example:
public class Main {
public static void main(String[] args) {
StringBuffer javascript = null;
ScriptEngine runtime = null;
try {
runtime = new ScriptEngineManager().getEngineByName("javascript");
javascript = new StringBuffer();
javascript.append("1 + 1");
double result = (Double) runtime.eval(javascript.toString());
System.out.println("Result: " + result);
} catch (Exception ex) {
System.out.println(ex.getMessage());
}

I got here with a bit more general problem - I wanted to find files in directories matching pattern but not in their subdirectories.
My solution (assuming we're looking for all cpp files living directly in arch directories):
find . -path "*/arch/*/*" -prune -o -path "*/arch/*.cpp" -print
I couldn't use maxdepth since it limited search in the first place, and didn't know names of subdirectories that I wanted to exclude.
You should add overflow: hidden to your styles:
Js:
<Button style={styles.submit}>Submit</Button>
Styles:
submit {
backgroundColor: '#68a0cf';
overflow: 'hidden';
}
Standard UITableViewCell already contains UIImageView that appears to the left to all your labels if its image is set. You can access it using imageView property:
cell.imageView.image = someImage;
If for some reason standard behavior does not suit your needs (note that you can customize properties of that standard image view) then you can add your own UIImageView to the cell as Aman suggested in his answer. But in that approach you'll have to manage cell's layout yourself (e.g. make sure that cell labels do not overlap image). And do not add subviews to the cell directly - add them to cell's contentView:
// DO NOT!
[cell addSubview:imv];
// DO:
[cell.contentView addSubview:imv];

Read up on Cancellation (which was introduced in .NET 4.0 and is largely unchanged since then) and the Task-Based Asynchronous Pattern, which provides guidelines on how to use CancellationToken with async methods.
To summarize, you pass a CancellationToken into each method that supports cancellation, and that method must check it periodically.
private async Task TryTask()
{
CancellationTokenSource source = new CancellationTokenSource();
source.CancelAfter(TimeSpan.FromSeconds(1));
Task<int> task = Task.Run(() => slowFunc(1, 2, source.Token), source.Token);
// (A canceled task will raise an exception when awaited).
await task;
}
private int slowFunc(int a, int b, CancellationToken cancellationToken)
{
string someString = string.Empty;
for (int i = 0; i < 200000; i++)
{
someString += "a";
if (i % 1000 == 0)
cancellationToken.ThrowIfCancellationRequested();
}
return a + b;
}

Furthermore, check out section 1.2.1.1.4.2 - Floating-Point Type Memory Layout of the C/CPP Reference Book, it explains super well and in simple terms the memory representation/layout of all the floating-point types and how to decode them (w/ illustrations) following the actually IEEE 754 Floating-Point specification.
It also has links to really really good ressources that explain even deeper.

If you are trying to do an in-place update of text within a file, this is much easier to reason about in my mind.

Never ever choose a fixed pivot - this can be attacked to exploit your algorithm's worst case O(n2) runtime, which is just asking for trouble. Quicksort's worst case runtime occurs when partitioning results in one array of 1 element, and one array of n-1 elements. Suppose you choose the first element as your partition. If someone feeds an array to your algorithm that is in decreasing order, your first pivot will be the biggest, so everything else in the array will move to the left of it. Then when you recurse, the first element will be the biggest again, so once more you put everything to the left of it, and so on.
A better technique is the median-of-3 method, where you pick three elements at random, and choose the middle. You know that the element that you choose won't be the the first or the last, but also, by the central limit theorem, the distribution of the middle element will be normal, which means that you will tend towards the middle (and hence, nlog(n) time).
If you absolutely want to guarantee O(nlog(n)) runtime for the algorithm, the columns-of-5 method for finding the median of an array runs in O(n) time, which means that the recurrence equation for quicksort in the worst case will be:
T(n) = O(n) (find the median) + O(n) (partition) + 2T(n/2) (recurse left and right)
By the Master Theorem, this is O(nlog(n)). However, the constant factor will be huge, and if worst case performance is your primary concern, use a merge sort instead, which is only a little bit slower than quicksort on average, and guarantees O(nlog(n)) time (and will be much faster than this lame median quicksort).
Linux is now officially supported in brew - see the Homebrew 2.0.0 blog post. As shown on https://brew.sh, just copy/paste this into a command prompt:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
For local access, large numbers of directories/files doesn't seem to be an issue. However, if you're accessing it across a network, there's a noticeable performance hit after a few hundred (especially when accessed from Vista machines (XP to Windows Server w/NTFS seemed to run much faster in that regard)).
I am currently using Android Studio 1.4.
For importing and adding libraries, I used the following flow ->
1. Press **Alt+Ctr+Shift+S** or Go to **File --> Project** Structure to open up the Project Structure Dialog Box.
2. Click on **Modules** to which you want to link the JAR to and Go to the Dependency Tab.
3. Click on "**+**" Button to pop up Choose Library Dependency.
4. Search/Select the dependency and rebuild the project.
I used the above approach to import support v4 and v13 libraries.
I hope this is helpful and clears up the flow.
Just to expand on the answer(s) above, in my case, I required sending a yes/no against a single ID serialized to my backend catch.
I set the checkbox elements to contain the ID of a particular database column, aka (default checked):
(Laravel Blade)
<div class="checkbox">
<label>
<input type="checkbox" value="{{ $heading->id }}" checked> {{ $heading->name }}
</label>
</div>
When I did my submission, I grabbed the data with:
(jQuery)
let form = $('#formID input[type="checkbox"]').map(function() {
return { id: this.value, value: this.checked ? 1 : 0 };
}).get();
var data = JSON.stringify(form);
$.post( "/your/endpoint", data );
Let me try a complex computation using datetime and considering nulls or empty spaces. I am reducing 30 years on a datetime column and using apply method as well as lambda and converting datetime format. Line if x != '' else x will take care of all empty spaces or nulls accordingly.
df['Date'] = df['Date'].fillna('')
df['Date'] = df['Date'].apply(lambda x : ((datetime.datetime.strptime(str(x), '%m/%d/%Y') - datetime.timedelta(days=30*365)).strftime('%Y%m%d')) if x != '' else x)
Beware that -prune does not prevent descending into any directory as some have said. It prevents descending into directories that match the test it's applied to. Perhaps some examples will help (see the bottom for a regex example). Sorry for this being so lengthy.

The solution consists in a regex pattern matching open and closing parenthesis
String str = "Your(String)";
// parameter inside split method is the pattern that matches opened and closed parenthesis,
// that means all characters inside "[ ]" escaping parenthesis with "\\" -> "[\\(\\)]"
String[] parts = str.split("[\\(\\)]");
for (String part : parts) {
// I print first "Your", in the second round trip "String"
System.out.println(part);
}
Writing in Java 8's style, this can be solved in this way:
Arrays.asList("Your(String)".split("[\\(\\)]"))
.forEach(System.out::println);
I hope it is clear.

A more concise version
IF COL_LENGTH('table_name','column_name') IS NULL
BEGIN
/* Column does not exist or caller does not have permission to view the object */
END
The point about permissions on viewing metadata applies to all answers not just this one.
Note that the first parameter table name to COL_LENGTH can be in one, two, or three part name format as required.
An example referencing a table in a different database is
COL_LENGTH('AdventureWorks2012.HumanResources.Department','ModifiedDate')
One difference with this answer compared to using the metadata views is that metadata functions such as COL_LENGTH always only return data about committed changes irrespective of the isolation level in effect.
I also had this error. It worked normally after I clean up the cookies.
This method checks if a String contains a special character (based on your definition).
/**
* Returns true if s contains any character other than
* letters, numbers, or spaces. Returns false otherwise.
*/
public boolean containsSpecialCharacter(String s) {
return (s == null) ? false : s.matches("[^A-Za-z0-9 ]");
}
You can use the same logic to count special characters in a string like this:
/**
* Counts the number of special characters in s.
*/
public int getSpecialCharacterCount(String s) {
if (s == null || s.trim().isEmpty()) {
return 0;
}
int theCount = 0;
for (int i = 0; i < s.length(); i++) {
if (s.substring(i, 1).matches("[^A-Za-z0-9 ]")) {
theCount++;
}
}
return theCount;
}
Another approach is to put all the special chars in a String and use String.contains:
/**
* Counts the number of special characters in s.
*/
public int getSpecialCharacterCount(String s) {
if (s == null || s.trim().isEmpty()) {
return 0;
}
int theCount = 0;
String specialChars = "/*!@#$%^&*()\"{}_[]|\\?/<>,.";
for (int i = 0; i < s.length(); i++) {
if (specialChars.contains(s.substring(i, 1))) {
theCount++;
}
}
return theCount;
}
NOTE: You must escape the backslash and " character with a backslashes.
The above are examples of how to approach this problem in general.
For your exact problem as stated in the question, the answer by @LanguagesNamedAfterCoffee is the most efficient approach.
Based on the answer from @Ryan Ahearn, following is what I did on Ubuntu 16.04 to create a user front that only has permission for nginx's web dir /var/www/html.
Steps:
* pre-steps:
* basic prepare of server,
* create user 'dev'
which will be the owner of "/var/www/html",
*
* install nginx,
*
*
* create user 'front'
sudo useradd -d /home/front -s /bin/bash front
sudo passwd front
# create home folder, if not exists yet,
sudo mkdir /home/front
# set owner of new home folder,
sudo chown -R front:front /home/front
# switch to user,
su - front
# copy .bashrc, if not exists yet,
cp /etc/skel/.bashrc ~front/
cp /etc/skel/.profile ~front/
# enable color,
vi ~front/.bashrc
# uncomment the line start with "force_color_prompt",
# exit user
exit
*
* add to group 'dev',
sudo usermod -a -G dev front
* change owner of web dir,
sudo chown -R dev:dev /var/www
* change permission of web dir,
chmod 775 $(find /var/www/html -type d)
chmod 664 $(find /var/www/html -type f)
*
* re-login as 'front'
to make group take effect,
*
* test
*
* ok

Add your own .css file & put in it:
body{
background: navy;
}
Important: While including css files in html, first include the cdn bootstrap css, then only include your own .css file. This way stylings in your own css file overrides the default behaviour from bootstrap css.
Another way is download and unzip chromedriver and put 'chromedriver.exe' in C:\Python27\Scripts and then you need not to provide the path of driver, just
driver= webdriver.Chrome()
will work
c.Request["AP"] will read posted values. Also you need to use a submit button to post the form:

instead of
<input type=button value="Submit" />
"Ultra JSON" or simply "ujson" can handle having [] in your JSON file input. If you're reading a JSON input file into your program as a list of JSON elements; such as, [{[{}]}, {}, [], etc...] ujson can handle any arbitrary order of lists of dictionaries, dictionaries of lists.
You can find ujson in the Python package index and the API is almost identical to Python's built-in json library.
ujson is also much faster if you're loading larger JSON files. You can see the performance details in comparison to other Python JSON libraries in the same link provided.
