This can get more complicated depending on where PHP sits in your environment, since your question is quite broad. This may depend on whether there's a load-balancer and how it's configured. Here are are a few related questions:

arr: Array[java.lang.String] = Array(Hello, World)
I too have struggled with this new pagespeed metric.
Although I have found no practical way to get my score back up to %100 there are a few things I have found helpful.
Combining all css into one file helped a lot. All my sites are back up to %95 - %98.
The only other thing I could think of was to inline all the necessary css (which appears to be most of it - at least for my pages) on the first page to get the sweet high score. Although it may help your speed score this will probably make your page load slower though.
There is no way in Selenium to read the request or response headers. You could do it by instructing your browser to connect through a proxy that records this kind of information.
The usual way to change the user agent for Firefox is to set the variable "general.useragent.override"
in your Firefox profile. Note that this is independent from Selenium.
You can direct Selenium to use a profile different from the default one, like this:
from selenium import webdriver
profile = webdriver.FirefoxProfile()
profile.set_preference("general.useragent.override", "whatever you want")
driver = webdriver.Firefox(profile)
With Chrome, what you want to do is use the user-agent
command line option. Again, this is not a Selenium thing. You can invoke Chrome at the command line with chrome --user-agent=foo
to set the agent to the value foo
.
With Selenium you set it like this:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
opts = Options()
opts.add_argument("user-agent=whatever you want")
driver = webdriver.Chrome(chrome_options=opts)
Both methods above were tested and found to work. I don't know about other browsers.
Selenium does not have methods to query the user agent from an instance of WebDriver
. Even in the case of Firefox, you cannot discover the default user agent by checking what general.useragent.override
would be if not set to a custom value. (This setting does not exist before it is set to some value.)
Once the browser is started, however, you can get the user agent by executing:
agent = driver.execute_script("return navigator.userAgent")
The agent
variable will contain the user agent.
They both increment the number. ++i
is equivalent to i = i + 1
.
i++
and ++i
are very similar but not exactly the same. Both increment the number, but ++i
increments the number before the current expression is evaluted, whereas i++
increments the number after the expression is evaluated.
int i = 3;
int a = i++; // a = 3, i = 4
int b = ++a; // b = 4, a = 4

On top of what some others have said, from my understanding .NET and Java are better at memory allocation. E.g. they can compact memory as it gets fragmented while C++ cannot (natively, but it can if you're using a clever garbage collector).

I can't tell you what's best, but a tool I have used with success in the past was cx_Freeze. They recently updated (on Jan. 7, '17) to version 5.0.1 and it supports Python 3.6.
Here's the pypi https://pypi.python.org/pypi/cx_Freeze
The documentation shows that there is more than one way to do it, depending on your needs. http://cx-freeze.readthedocs.io/en/latest/overview.html
I have not tried it out yet, so I'm going to point to a post where the simple way of doing it was discussed. Some things may or may not have changed though.
To know the package owning (or providing) an already installed file:

I wrote my own library to achieve the intended behaviour in ios Maps app. It is a protocol oriented solution. So you don't need to inherit any base class instead create a sheet controller and configure as you wish. It also supports inner navigation/presentation with or without UINavigationController.

Just want to add one more way. Found it elsewhere, and is quite simple. Say I want to pass yes for all the prompts at command line for a command "execute_command", Then I would simply pipe yes to it.
yes | execute_command
This will use yes as the answer to all yes/no prompts.
In dynamic languages, when the interpreter import
s, it simply reads a file and evaluates it.
In C, external libraries are located by the linker at compile time to build the final object if the library is statically compiled, while for dynamic libraries a smaller version of the linker is called at runtime which remaps addresses and so makes code in the library available to the executable.
In Java, import
is simply used by the compiler to let you name your classes by their unqualified name, let's say String
instead of java.lang.String
. You don't really need to import java.lang.*
because the compiler does it by default. However this mechanism is just to save you some typing. Types in Java are fully qualified class names, so a String
is really a java.lang.String
object when the code is run. Packages are intended to prevent name clashes and allow two classes to have the same simple name, instead of relying on the old C convention of prefixing types like this. java_lang_String
. This is called namespacing.
BTW, in Java there's the static import construct, which allows to further save typing if you use lots of constants from a certain class. In a compilation unit (a .java file) which declares
import static java.lang.Math.*;
you can use the constant PI
in your code, instead of referencing it through Math.PI
, and the method cos()
instead of Math.cos()
. So for example you can write
double r = cos(PI * theta);
Once you understand that classes are always referenced by their fully qualified name in the final bytecode, you must understand how the class code is actually loaded. This happens the first time an object of that class is created, or the first time a static member of the class is accessed. At this time, the ClassLoader
tries to locate the class and instantiate it. If it can't find the class a NoClassDefFoundError
is thrown (or a a ClassNotFoundException
if the class is searched programmatically). To locate the class, the ClassLoader
usually checks the paths listed in the $CLASSPATH
environment variable.
To solve your problem, it seems you need an applet
element like this
<applet
codebase = "http://san.redenetimoveis.com"
archive="test.jar, core.jar"
code="com.colorfulwolf.webcamapplet.WebcamApplet"
width="550" height="550" >
BTW, you don't need to import the archives in the standard JRE.
If you're able to use matchAll
here's a trick:
Array.From
has a 'selector' parameter so instead of ending up with an array of awkward 'match' results you can project it to what you really need:
Array.from(str.matchAll(regexp), m => m[0]);
If you have named groups eg. (/(?<firstname>[a-z][A-Z]+)/g
) you could do this:
Array.from(str.matchAll(regexp), m => m.groups.firstName);
Apache Http Client APIs are very commonly used for calling HTTP Rest services.
Here is one of example of consuming HTTP GET call.
import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpUriRequest;
import org.apache.http.impl.client.HttpClientBuilder;
public class CallHTTPGetService {
public static void main(String[] args) throws ClientProtocolException, IOException {
HttpClient client = HttpClientBuilder.create().build();
HttpUriRequest httpUriRequest = new HttpGet("URL");
HttpResponse response = client.execute(httpUriRequest);
System.out.println(response);
}
}

I've just updated this to MVC 3 in case anyone finds it useful: Conditional Validation in ASP.NET MVC 3.
Consider IPv4 address as "ip".
if re.match(r'^((\d{1,2}|1\d{2}|2[0-4]\d|25[0-5])\.){3}(\d{1,2}|1\d{2}|2[0-4]\d|25[0-5])$', ip):
print "Valid IP"
else:
print "Invalid IP"
You could store this into a temporary table.
So instead of doing the CTE/sub query you would use a temp table.
Good article on these here http://codingsight.com/introduction-to-temporary-tables-in-sql-server/
One general solution to such tiny errors is that you close eclipse and start is again.. 3 irritating problems were solved.. its the problem with eclipse.. some times it didn resolve "R.id", the it didn find @string/somebutton, and then again some random thing... if nothing logical comes in your mind, try this, n conjure d result.. :)
First check the variables declared using proper Datatypes. I had a same problem then I have checked, by mistake I declared SAPUser as int datatype so that the error occurred. One more thing XML file stores its data using concept like array but its first index starts having +1. e.g. if error is in(7,2) then check for 6th line always.....
I use this version
<style><%@include file="/WEB-INF/css/style.css"%></style>
You can replace database value in date_default_timezone_set function, date_default_timezone_set(SOME_PHP_VARIABLE); but just needs to take care of exact values relevant to the timezones.
For a start, your answer
variable should be of type char
, not char*
.
As for the if
statement:
if (answer == ('Y' || 'y'))
This is first evaluating 'Y' || 'y'
which, in Boolean logic (and for ASCII) is true since both of them are "true" (non-zero). In other words, you'd only get the if
statement to fire if you'd somehow entered CTRLA (again, for ASCII, and where a true values equates to 1)*a.
You could use the more correct:
if ((answer == 'Y') || (answer == 'y'))
but you really should be using:
if (toupper(answer) == 'Y')
since that's the more portable way to achieve the same end.
*a You may be wondering why I'm putting in all sorts of conditionals for my statements. While the vast majority of C implementations use ASCII and certain known values, it's not necessarily mandated by the ISO standards. I know for a fact that at least one compiler still uses EBCDIC so I don't like making unwarranted assumptions.
Something I completely missed: the non-wrapping behaviour of <pre>
can be controlled with CSS. So this gives the exact result I was looking for:
code { _x000D_
background: hsl(220, 80%, 90%); _x000D_
}_x000D_
_x000D_
pre {_x000D_
white-space: pre-wrap;_x000D_
background: hsl(30,80%,90%);_x000D_
}
_x000D_
Here's an example demonstrating the <code><code></code> tag._x000D_
_x000D_
<pre>_x000D_
Here's a very long pre-formatted formatted using the <pre> tag. Notice how it wraps? It goes on and on and on and on and on and on and on and on and on and on..._x000D_
</pre>
_x000D_
There's really no easy way to mix fluid and fixed widths with Bootstrap 3. It's meant to be like this, as the grid system is designed to be a fluid, responsive thing. You could try hacking something up, but it would go against what the Responsive Grid system is trying to do, the intent of which is to make that layout flow across different device types.
If you need to stick with this layout, I'd consider laying out your page with custom CSS and not using the grid.
fun TextView.addImage(atText: String, @DrawableRes imgSrc: Int, imgWidth: Int, imgHeight: Int) {
val ssb = SpannableStringBuilder(this.text)
val drawable = ContextCompat.getDrawable(this.context, imgSrc) ?: return
drawable.mutate()
drawable.setBounds(0, 0,
imgWidth,
imgHeight)
val start = text.indexOf(atText)
ssb.setSpan(VerticalImageSpan(drawable), start, start + atText.length, Spannable.SPAN_INCLUSIVE_EXCLUSIVE)
this.setText(ssb, TextView.BufferType.SPANNABLE)
}
VerticalImageSpan
class from great answer
https://stackoverflow.com/a/38788432/5381331
Using
val textView = findViewById<TextView>(R.id.textview)
textView.setText("Send an [email-icon] to [email protected].")
textView.addImage("[email-icon]", R.drawable.ic_email,
resources.getDimensionPixelOffset(R.dimen.dp_30),
resources.getDimensionPixelOffset(R.dimen.dp_30))
Result
Note
Why VerticalImageSpan
class?
ImageSpan.ALIGN_CENTER
attribute requires API 29.
Also, after the test, I see that ImageSpan.ALIGN_CENTER
only work if the image smaller than the text, if the image bigger than the text then only image is in center, text not center, it align on bottom of image
IMHO, one point that is missing in this discussion is that whatever variable you use, it is guaranteed to always point at the appropriate folder. This becomes critical in the rare cases where Windows is installed on a drive other than C:\
You simply need to do a SUBSTR on the string in col3....
Select col1, col2, REPLACE(substr(col3, instr(col3, 'Client Name'),
(instr(col3, '|', instr(col3, 'Client Name') -
instr(col3, 'Client Name'))
),
'Client Name = ',
'')
from Table01
And yes, that is a bad DB design for the reasons stated in the original issue
There is no difference in C++, but I believe in C it would allow you to declare instances of the struct Foo without explicitly doing:
struct Foo bar;
In case when you load all <options ....></options>
by Ajax call
Follow these step to do this.
1). Create a separate method for set value of drop-down
For Ex:
function set_ip_base_country(countryCode)
$('#country').val(countryCode)
}
2). Call this method when ajax call success all html append task complete
For Ex:
success: function (doc) {
.....
.....
$("#country").append('<option style="color:black;" value="' + key + '">' + value + '</option>')
set_ip_base_country(ip_base_country)
}
The data containing the date column can be read by using the below code:
data = pd.csv(file_path,parse_dates=[date_column])
Once the data is read by using the above line of code, the column containing the information about the date can be accessed using pd.date_time()
like:
pd.date_time(data[date_column], format = '%d/%m/%y')
to change the format of date as per the requirement.
Every time setColor
gets hit, you are setting count = 1. You would need to define count
outside of the scope of the function. Example:
var count=1;
function setColor(btn, color){
var property = document.getElementById(btn);
if (count == 0){
property.style.backgroundColor = "#FFFFFF"
count=1;
}
else{
property.style.backgroundColor = "#7FFF00"
count=0;
}
}
For future searchers... The following is a jQuery-ified version of FlySwat's accepted answer:
var labels = $("label");
for (var i = 0; i < labels.length; i++) {
var fieldId = labels[i].htmlFor;
if (fieldId != "") {
var elem = $("#" + fieldId);
if (elem.length != 0) {
elem.data("label", $(labels[i]));
}
}
}
Using:
$("#myFormElemId").data("label").css("border","3px solid red");
Well now will be different after angular 5:
{{ number | currency :'GBP':'symbol':'1.2-2' }}
I just encountered the same problem myself.
... = reader["myYear"] as int?;
works and is clean.
It works with any type without an issue. If the result is DBNull, it returns null as the conversion fails.

I use Git with Visual Studio for my port of Protocol Buffers to C#. I don't use the GUI - I just keep a command line open as well as Visual Studio.
For the most part it's fine - the only problem is when you want to rename a file. Both Git and Visual Studio would rather that they were the one to rename it. I think that renaming it in Visual Studio is the way to go though - just be careful what you do at the Git side afterwards. Although this has been a bit of a pain in the past, I've heard that it actually should be pretty seamless on the Git side, because it can notice that the contents will be mostly the same. (Not entirely the same, usually - you tend to rename a file when you're renaming the class, IME.)
But basically - yes, it works fine. I'm a Git newbie, but I can get it to do everything I need it to. Make sure you have a git ignore file for bin and obj, and *.user.

I believe you need to reference the current HttpContext
if you are outside of the controller. The MVC controllers have a base reference to the current context. However, outside of that, you have to explicitly declare you want the current HttpContext
return HttpContext.Current.GetOwinContext().Authentication;
As for it not showing up, a new MVC 5 project template using the code you show above (the IAuthenticationManager
) has the following using statements at the top of the account controller:
using System.Threading.Tasks;
using System.Web;
using System.Web.Mvc;
using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.EntityFramework;
using Microsoft.Owin.Security;
using WebApplication2.Models;
Commenting out each one, it appears the GetOwinContext()
is actually a part of the System.Web.Mvc assembly.
I also struggled finding articles on how to just generate the token part. I never found one and wrote my own. So if it helps:
The things to do are:
Microsoft.Owin
Microsoft.Owin.Host.SystemWeb
Microsoft.Owin.Security.OAuth
Microsoft.AspNet.Identity.Owin
startup
classThen create a HTML and a JavaScript (index.js
) file with these contents:

var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function () {
if (xmlhttp.readyState === 4 && xmlhttp.status === 200) {
alert(xmlhttp.responseText);
}
}
xmlhttp.open("POST", "/token", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send(loginData);

Thanks to duncan answer, I end up with this:
marker.addListener('mouseover', () => infoWindow.open(map, marker))
marker.addListener('mouseout', () => infoWindow.close())
An explanation is given here:
So if your program is using math functions and including
math.h
, then you need to explicitly link the math library by passing the-lm
flag. The reason for this particular separation is that mathematicians are very picky about the way their math is being computed and they may want to use their own implementation of the math functions instead of the standard implementation. If the math functions were lumped intolibc.a
it wouldn't be possible to do that.
[Edit]
I'm not sure I agree with this, though. If you have a library which provides, say, sqrt()
, and you pass it before the standard library, a Unix linker will take your version, right?
From the man page:
search, -S text|/text/ Perform a substring search of formula names for text. If text is surrounded with slashes, then it is interpreted as a regular expression. If no search term is given, all available formula are displayed.
For your purposes, brew search
will suffice.

So, the trick here is to use absolute positioning calc
like this:
top: calc(50% - XYpx);
left: calc(50% - XYpx);
where XYpx is half the size of your image, in my case, the image was a square. Of course, in this now obsolete case, the image must also change its size proportionally in response to window resize to be able to remain at the center without looking out of proportion.
You should probably be looking to the configuration that controls the underlying platform TLS implementation via -Djdk.tls.client.protocols=TLSv1.2
.
In modern MongoDB releases you can brute force this with $slice
just off the basic aggregation result. For "large" results, run parallel queries instead for each grouping ( a demonstration listing is at the end of the answer ), or wait for SERVER-9377 to resolve, which would allow a "limit" to the number of items to $push
to an array.
db.books.aggregate([
{ "$group": {
"_id": {
"addr": "$addr",
"book": "$book"
},
"bookCount": { "$sum": 1 }
}},
{ "$group": {
"_id": "$_id.addr",
"books": {
"$push": {
"book": "$_id.book",
"count": "$bookCount"
},
},
"count": { "$sum": "$bookCount" }
}},
{ "$sort": { "count": -1 } },
{ "$limit": 2 },
{ "$project": {
"books": { "$slice": [ "$books", 2 ] },
"count": 1
}}
])
Still not resolving SERVER-9377, but in this release $lookup
allows a new "non-correlated" option which takes an "pipeline"
expression as an argument instead of the "localFields"
and "foreignFields"
options. This then allows a "self-join" with another pipeline expression, in which we can apply $limit
in order to return the "top-n" results.
db.books.aggregate([
{ "$group": {
"_id": "$addr",
"count": { "$sum": 1 }
}},
{ "$sort": { "count": -1 } },
{ "$limit": 2 },
{ "$lookup": {
"from": "books",
"let": {
"addr": "$_id"
},
"pipeline": [
{ "$match": {
"$expr": { "$eq": [ "$addr", "$$addr"] }
}},
{ "$group": {
"_id": "$book",
"count": { "$sum": 1 }
}},
{ "$sort": { "count": -1 } },
{ "$limit": 2 }
],
"as": "books"
}}
])
The other addition here is of course the ability to interpolate the variable through $expr
using $match
to select the matching items in the "join", but the general premise is a "pipeline within a pipeline" where the inner content can be filtered by matches from the parent. Since they are both "pipelines" themselves we can $limit
each result separately.
This would be the next best option to running parallel queries, and actually would be better if the $match
were allowed and able to use an index in the "sub-pipeline" processing. So which is does not use the "limit to $push
" as the referenced issue asks, it actually delivers something that should work better.
You seem have stumbled upon the top "N" problem. In a way your problem is fairly easy to solve though not with the exact limiting that you ask for:
db.books.aggregate([
{ "$group": {
"_id": {
"addr": "$addr",
"book": "$book"
},
"bookCount": { "$sum": 1 }
}},
{ "$group": {
"_id": "$_id.addr",
"books": {
"$push": {
"book": "$_id.book",
"count": "$bookCount"
},
},
"count": { "$sum": "$bookCount" }
}},
{ "$sort": { "count": -1 } },
{ "$limit": 2 }
])
Now that will give you a result like this:
{
"result" : [
{
"_id" : "address1",
"books" : [
{
"book" : "book4",
"count" : 1
},
{
"book" : "book5",
"count" : 1
},
{
"book" : "book1",
"count" : 3
}
],
"count" : 5
},
{
"_id" : "address2",
"books" : [
{
"book" : "book5",
"count" : 1
},
{
"book" : "book1",
"count" : 2
}
],
"count" : 3
}
],
"ok" : 1
}
So this differs from what you are asking in that, while we do get the top results for the address values the underlying "books" selection is not limited to only a required amount of results.
This turns out to be very difficult to do, but it can be done though the complexity just increases with the number of items you need to match. To keep it simple we can keep this at 2 matches at most:
db.books.aggregate([
{ "$group": {
"_id": {
"addr": "$addr",
"book": "$book"
},
"bookCount": { "$sum": 1 }
}},
{ "$group": {
"_id": "$_id.addr",
"books": {
"$push": {
"book": "$_id.book",
"count": "$bookCount"
},
},
"count": { "$sum": "$bookCount" }
}},
{ "$sort": { "count": -1 } },
{ "$limit": 2 },
{ "$unwind": "$books" },
{ "$sort": { "count": 1, "books.count": -1 } },
{ "$group": {
"_id": "$_id",
"books": { "$push": "$books" },
"count": { "$first": "$count" }
}},
{ "$project": {
"_id": {
"_id": "$_id",
"books": "$books",
"count": "$count"
},
"newBooks": "$books"
}},
{ "$unwind": "$newBooks" },
{ "$group": {
"_id": "$_id",
"num1": { "$first": "$newBooks" }
}},
{ "$project": {
"_id": "$_id",
"newBooks": "$_id.books",
"num1": 1
}},
{ "$unwind": "$newBooks" },
{ "$project": {
"_id": "$_id",
"num1": 1,
"newBooks": 1,
"seen": { "$eq": [
"$num1",
"$newBooks"
]}
}},
{ "$match": { "seen": false } },
{ "$group":{
"_id": "$_id._id",
"num1": { "$first": "$num1" },
"num2": { "$first": "$newBooks" },
"count": { "$first": "$_id.count" }
}},
{ "$project": {
"num1": 1,
"num2": 1,
"count": 1,
"type": { "$cond": [ 1, [true,false],0 ] }
}},
{ "$unwind": "$type" },
{ "$project": {
"books": { "$cond": [
"$type",
"$num1",
"$num2"
]},
"count": 1
}},
{ "$group": {
"_id": "$_id",
"count": { "$first": "$count" },
"books": { "$push": "$books" }
}},
{ "$sort": { "count": -1 } }
])
So that will actually give you the top 2 "books" from the top two "address" entries.
But for my money, stay with the first form and then simply "slice" the elements of the array that are returned to take the first "N" elements.
The demonstration code is appropriate for usage with current LTS versions of NodeJS from v8.x and v10.x releases. That's mostly for the async/await
syntax, but there is nothing really within the general flow that has any such restriction, and adapts with little alteration to plain promises or even back to plain callback implementation.

Enumerations in C are numbers that have convenient names inside your code. They are not strings, and the names assigned to them in the source code are not compiled into your program, and so they are not accessible at runtime.
The only way to get what you want is to write a function yourself that translates the enumeration value into a string. E.g. (assuming here that you move the declaration of enum Days
outside of main
):
const char* getDayName(enum Days day)
{
switch (day)
{
case Sunday: return "Sunday";
case Monday: return "Monday";
/* etc... */
}
}
/* Then, later in main: */
printf("%s", getDayName(TheDay));
Alternatively, you could use an array as a map, e.g.
const char* dayNames[] = {"Sunday", "Monday", "Tuesday", /* ... etc ... */ };
/* ... */
printf("%s", dayNames[TheDay]);
But here you would probably want to assign Sunday = 0
in the enumeration to be safe... I'm not sure if the C standard requires compilers to begin enumerations from 0, although most do (I'm sure someone will comment to confirm or deny this).
I prefer to return the identity value as an output parameter. The result of the SP should indicate whether it succeeded or not. A value of 0 indicates the SP successfully completed, a non-zero value indicates an error. Also, if you ever need to make a change and return an additional value from the SP you don't need to make any changes other than adding an additional output parameter.
In case you're using a UITabBarController
:
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
self.tabBarController?.navigationItem.hidesBackButton = true
}
Just use the function for parsing a CSV file

$row = 1;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
echo "<p> $num fields in line $row: <br /></p>\n";
$row++;
for ($c=0; $c < $num; $c++) {
echo $data[$c] . "<br />\n";
}
}
fclose($handle);
}

The accepted answer does not "make Git "forget" about a file..." (historically). It only makes git ignore the file in the present/future.
This method makes git completely forget ignored files (past/present/future), but does not delete anything from working directory (even when re-pulled from remote).
This method requires usage of
/.git/info/exclude
(preferred) OR a pre-existing.gitignore
in all the commits that have files to be ignored/forgotten. 1All methods of enforcing git ignore behavior after-the-fact effectively re-write history and thus have significant ramifications for any public/shared/collaborative repos that might be pulled after this process. 2
General advice: start with a clean repo - everything committed, nothing pending in working directory or index, and make a backup!
Also, the comments/revision history of this answer (and revision history of this question) may be useful/enlightening.
#commit up-to-date .gitignore (if not already existing)
#this command must be run on each branch
git add .gitignore
git commit -m "Create .gitignore"
#apply standard git ignore behavior only to current index, not working directory (--cached)
#if this command returns nothing, ensure /.git/info/exclude AND/OR .gitignore exist
#this command must be run on each branch
git ls-files -z --ignored --exclude-standard | xargs -0 git rm --cached
#Commit to prevent working directory data loss!
#this commit will be automatically deleted by the --prune-empty flag in the following command
#this command must be run on each branch
git commit -m "ignored index"
#Apply standard git ignore behavior RETROACTIVELY to all commits from all branches (--all)
#This step WILL delete ignored files from working directory UNLESS they have been dereferenced from the index by the commit above
#This step will also delete any "empty" commits. If deliberate "empty" commits should be kept, remove --prune-empty and instead run git reset HEAD^ immediately after this command
git filter-branch --tree-filter 'git ls-files -z --ignored --exclude-standard | xargs -0 git rm -f --ignore-unmatch' --prune-empty --tag-name-filter cat -- --all
#List all still-existing files that are now ignored properly
#if this command returns nothing, it's time to restore from backup and start over
#this command must be run on each branch
git ls-files --other --ignored --exclude-standard
Finally, follow the rest of this GitHub guide (starting at step 6) which includes important warnings/information about the commands below.
git push origin --force --all
git push origin --force --tags
git for-each-ref --format="delete %(refname)" refs/original | git update-ref --stdin
git reflog expire --expire=now --all
git gc --prune=now
Other devs that pull from now-modified remote repo should make a backup and then:
#fetch modified remote
git fetch --all
#"Pull" changes WITHOUT deleting newly-ignored files from working directory
#This will overwrite local tracked files with remote - ensure any local modifications are backed-up/stashed
git reset FETCH_HEAD
1 Because /.git/info/exclude
can be applied to all historical commits using the instructions above, perhaps details about getting a .gitignore
file into the historical commit(s) that need it is beyond the scope of this answer. I wanted a proper .gitignore
to be in the root commit, as if it was the first thing I did. Others may not care since /.git/info/exclude
can accomplish the same thing regardless where the .gitignore
exists in the commit history, and clearly re-writing history is a very touchy subject, even when aware of the ramifications.
FWIW, potential methods may include git rebase
or a git filter-branch
that copies an external .gitignore
into each commit, like the answers to this question
2 Enforcing git ignore behavior after-the-fact by committing the results of a standalone git rm --cached
command may result in newly-ignored file deletion in future pulls from the force-pushed remote. The --prune-empty
flag in the following git filter-branch
command avoids this problem by automatically removing the previous "delete all ignored files" index-only commit. Re-writing git history also changes commit hashes, which will wreak havoc on future pulls from public/shared/collaborative repos. Please understand the ramifications fully before doing this to such a repo. This GitHub guide specifies the following:
Tell your collaborators to rebase, not merge, any branches they created off of your old (tainted) repository history. One merge commit could reintroduce some or all of the tainted history that you just went to the trouble of purging.
Alternative solutions that do not affect the remote repo are git update-index --assume-unchanged </path/file>
or git update-index --skip-worktree <file>
, examples of which can be found here.

In ASP.NET MVC 3 You should do something like this:
// Say you have a bit of HTML like this in your controller:
ViewBag.Stuff = "<li>Menu</li>"
// Then you can do this in your view:
@MvcHtmlString.Create(ViewBag.Stuff)
Basically this is what you need to do:
in the first activity:
Intent intent = new Intent();
intent.setAction(this, SecondActivity.class);
intent.putExtra(tag, value);
startActivity(intent);
and in the second activtiy:
Intent intent = getIntent();
intent.getBooleanExtra(tag, defaultValue);
intent.getStringExtra(tag, defaultValue);
intent.getIntegerExtra(tag, defaultValue);
one of the get-functions will give return you the value, depending on the datatype you are passing through.
you can use this method just pass your date to it

{
NSString * dateString = [NSString stringWithFormat: @"%@",string];

This is really linked to HotSpot and the default option values (Java HotSpot VM Options) which differ between client and server configuration.
From Chapter 2 of the whitepaper (The Java HotSpot Performance Engine Architecture):
The JDK includes two flavors of the VM -- a client-side offering, and a VM tuned for server applications. These two solutions share the Java HotSpot runtime environment code base, but use different compilers that are suited to the distinctly unique performance characteristics of clients and servers. These differences include the compilation inlining policy and heap defaults.
Although the Server and the Client VMs are similar, the Server VM has been specially tuned to maximize peak operating speed. It is intended for executing long-running server applications, which need the fastest possible operating speed more than a fast start-up time or smaller runtime memory footprint.
The Client VM compiler serves as an upgrade for both the Classic VM and the just-in-time (JIT) compilers used by previous versions of the JDK. The Client VM offers improved run time performance for applications and applets. The Java HotSpot Client VM has been specially tuned to reduce application start-up time and memory footprint, making it particularly well suited for client environments. In general, the client system is better for GUIs.
So the real difference is also on the compiler level:
The Client VM compiler does not try to execute many of the more complex optimizations performed by the compiler in the Server VM, but in exchange, it requires less time to analyze and compile a piece of code. This means the Client VM can start up faster and requires a smaller memory footprint.
The Server VM contains an advanced adaptive compiler that supports many of the same types of optimizations performed by optimizing C++ compilers, as well as some optimizations that cannot be done by traditional compilers, such as aggressive inlining across virtual method invocations. This is a competitive and performance advantage over static compilers. Adaptive optimization technology is very flexible in its approach, and typically outperforms even advanced static analysis and compilation techniques.
Note: The release of jdk6 update 10 (see Update Release Notes:Changes in 1.6.0_10) tried to improve startup time, but for a different reason than the hotspot options, being packaged differently with a much smaller kernel.
G. Demecki points out in the comments that in 64-bit versions of JDK, the -client
option is ignored for many years.
See Windows java
command:
-client
Selects the Java HotSpot Client VM.
A 64-bit capable JDK currently ignores this option and instead uses the Java Hotspot Server VM.

The scenario in question is better served by each Fragment adding its own menu items and directly handling onOptionsItemSelected(), as described in official documentation. It is better to avoid undocumented tricks.
If I have one thing that I love to share with respect to CSS, it's MY FAVE WAY OF CENTERING THINGS ALONG BOTH AXES!!!
Advantages of this method:
I always do this by using 2 classes: One to specify the parent element, whose content will be centered (.centered-wrapper
), and the 2nd one to specify which child of the parent is centered (.centered-content
). This 2nd class is useful in the case where the parent has multiple children, but only 1 needs to be centered).
In this case, body
will be the .centered-wrapper
, and an inner div
will be .centered-content
.
<html>
<head>...</head>
<body class="centered-wrapper">
<div class="centered-content">...</div>
</body>
</html>
The idea for centering will now be to make .centered-content
an inline-block
. This will easily facilitate horizontal centering, through text-align: center;
, and also allows for vertical centering as you shall see.
.centered-wrapper {
position: relative;
text-align: center;
}
.centered-wrapper:before {
content: "";
position: relative;
display: inline-block;
width: 0; height: 100%;
vertical-align: middle;
}
.centered-content {
display: inline-block;
vertical-align: middle;
}
This gives you 2 really reusable classes for centering any child inside of any parent! Just add the .centered-wrapper
and .centered-content
classes.
So, what's up with that :before
element? It facilitates vertical-align: middle;
and is necessary because vertical alignment isn't relative to the height of the parent - vertical alignment is relative to the height of the tallest sibling!!!. Therefore, by ensuring that there is a sibling whose height is the parent's height (100% height, 0 width to make it invisible), we know that vertical alignment will be with respect to the parent's height.
One last thing: You need to ensure that your html
and body
tags are the size of the window so that centering to them is the same as centering to the browser!
html, body {
width: 100%;
height: 100%;
padding: 0;
margin: 0;
}
Do it like this. This approach lets you search a file of any size (big size won't crash the script) and will return ALL lines that match the string you want.
<?php
$searchthis = "mystring";
$matches = array();
$handle = @fopen("path/to/inputfile.txt", "r");
if ($handle)
{
while (!feof($handle))
{
$buffer = fgets($handle);
if(strpos($buffer, $searchthis) !== FALSE)
$matches[] = $buffer;
}
fclose($handle);
}
//show results:
print_r($matches);
?>
Note the way strpos
is used with !==
operator.
If you do not want to install sqlplus
on your server/machine then the following command-line tool can be your friend. It is a simple Java application, only Java 8 that you need in order to you can execute this tool.
The tool can be used to run any SQL from the Linux bash or Windows command line.
Example:
java -jar sql-runner-0.2.0-with-dependencies.jar \
-j jdbc:oracle:thin:@//oracle-db:1521/ORCLPDB1.localdomain \
-U "SYS as SYSDBA" \
-P Oradoc_db1 \
"select 1 from dual"
Documentation is here.
You can download the binary file from here.
Use a pattern along these lines:
function getValue(file) {
return lookupValue(file);
}
getValue('myFile.txt').then(function(res) {
// do whatever with res here
});
(although this is a bit redundant, I'm sure your actual code is more complicated)
What is the value range? Is it 0 through 10? If so, then try:
SELECT REPLICATE('0',2-LEN(@t)) + CAST(@t AS VARCHAR)
That handles 0 through 9 as well as 10 through 99.
Now, tinyint can go up to the value of 255. If you want to handle > 99 through 255, then try this solution:
declare @t TINYINT
set @t =233
SELECT ISNULL(REPLICATE('0',2-LEN(@t)),'') + CAST(@t AS VARCHAR)
To understand the solution, the expression to the left of the + calculates the number of zeros to prefix to the string.
In case of the value 3, the length is 1. 2 - 1 is 1. REPLICATE Adds one zero. In case of the value 10, the length is 2. 2 - 2 is 0. REPLICATE Adds nothing. In the case of the value 100, the length is -1 which produces a NULL. However, the null value is handled and set to an empty string.
Now if you decide that because tinyint can contain up to 255 and you want your formatting as three characters, just change the 2-LEN to 3-LEN in the left expression and you're set.
The compiler cannot guess what should be passed for the base constructor argument. You have to do it explicitly:
public class child : parent {
public child(int i) : base(i) {
Console.WriteLine("child");
}
}
Check that there are no missing references - to do this, go to the database window and click on "Modules", then "Design", then select the menu "Tools" and then "References". Or try doing a compile and see if it compiles fully (go to the Debug menu then select Compile) - it might tell you of a missing reference e.g. Microsoft Office 11.0 Object Library. Select References from the Tools menu again and see if any references are ticked and say "MISSING:". In some cases you can select a different version from the list, if 11.0 is missing, look for version 12.0 then recompile. That usually does the trick for me.
I would inherit from ValueError
class IllegalArgumentError(ValueError):
pass
It is sometimes better to create your own exceptions, but inherit from a built-in one, which is as close to what you want as possible.
If you need to catch that specific error, it is helpful to have a name.
You can also use a fadeIn/FadeOut Combo, too....
$('.test').bind('click', function(){
$('.div1').fadeIn(500);
$('.div2').fadeOut(500);
$('.div3').fadeOut(500);
return false;
});
Something like the following example. Note I'm in Eastern Australia (UTC + 10 hours at the moment).
>>> import datetime
>>> dtnow = datetime.datetime.now();dtutcnow = datetime.datetime.utcnow()
>>> dtnow
datetime.datetime(2010, 8, 4, 9, 33, 9, 890000)
>>> dtutcnow
datetime.datetime(2010, 8, 3, 23, 33, 9, 890000)
>>> delta = dtnow - dtutcnow
>>> delta
datetime.timedelta(0, 36000)
>>> hh,mm = divmod((delta.days * 24*60*60 + delta.seconds + 30) // 60, 60)
>>> hh,mm
(10, 0)
>>> "%s%+02d:%02d" % (dtnow.isoformat(), hh, mm)
'2010-08-04T09:33:09.890000+10:00'
>>>
Do whatever you want as long as its minimal, consistent, and doesn't break any rules.
Personally, I find the Boost style easiest; it matches the standard library (giving a uniform look to code) and is simple. I personally tack on m
and p
prefixes to members and parameters, respectively, giving:
#ifndef NAMESPACE_NAMES_THEN_PRIMARY_CLASS_OR_FUNCTION_THEN_HPP
#define NAMESPACE_NAMES_THEN_PRIMARY_CLASS_OR_FUNCTION_THEN_HPP
#include <boost/headers/go/first>
#include <boost/in_alphabetical/order>
#include <then_standard_headers>
#include <in_alphabetical_order>
#include "then/any/detail/headers"
#include "in/alphabetical/order"
#include "then/any/remaining/headers/in"
// (you'll never guess)
#include "alphabetical/order/duh"
#define NAMESPACE_NAMES_THEN_MACRO_NAME(pMacroNames) ARE_ALL_CAPS
namespace lowercase_identifers
{
class separated_by_underscores
{
public:
void because_underscores_are() const
{
volatile int mostLikeSpaces = 0; // but local names are condensed
while (!mostLikeSpaces)
single_statements(); // don't need braces
for (size_t i = 0; i < 100; ++i)
{
but_multiple(i);
statements_do();
}
}
const complex_type& value() const
{
return mValue; // no conflict with value here
}
void value(const complex_type& pValue)
{
mValue = pValue ; // or here
}
protected:
// the more public it is, the more important it is,
// so order: public on top, then protected then private
template <typename Template, typename Parameters>
void are_upper_camel_case()
{
// gman was here
}
private:
complex_type mValue;
};
}
#endif
That. (And like I've said in comments, do not adopt the Google Style Guide for your code, unless it's for something as inconsequential as naming convention.)
Sometime I have to work from home and connect to office through vpn. Internal domain names should be resolved to different IPs at home. There are several names that have to be changed between office and home. For example:
At office, a => 192.168.0.3, b => 192.168.0.52.
At home, a => 10.6.1.7, b => 10.4.5.23.
My solution is to create two files: C:\WINDOWS\system32\drivers\etc\hosts-home and C:\WINDOWS\system32\drivers\etc\hosts-office. Each of them contains set of name-to-IP mapping. From Administrator PowerShell, When I work at the office, execute
C:\WINDOWS\system32> cp .\drivers\etc\hosts-office .\drivers\etc\hosts
When I arrive at home, execute
C:\WINDOWS\system32> cp .\drivers\etc\hosts-home .\drivers\etc\hosts
Changing my header to the following solve the problem:
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
You sure can do this!
//make a regular expression out of your needle
var needle = 'le'
var re = new RegExp(needle,'gi');
var haystack = 'I learned to play the Ukulele';
var results = new Array();//this is the results you want
while (re.exec(haystack)){
results.push(re.lastIndex);
}
Edit: learn to spell RegExp
Also, I realized this isn't exactly what you want, as lastIndex
tells us the end of the needle not the beginning, but it's close - you could push re.lastIndex-needle.length
into the results array...
Edit: adding link
@Tim Down's answer uses the results object from RegExp.exec(), and all my Javascript resources gloss over its use (apart from giving you the matched string). So when he uses result.index
, that's some sort of unnamed Match Object. In the MDC description of exec, they actually describe this object in decent detail.
Differences between an XML Schema Definition (XSD) and Document Type Definition (DTD) include:
Not all these bullet points are 100% accurate, but you get the gist.
On the other hand:
Just another example how to achieve desired effect
class Foo(object):
_bar = None
@property
def bar(self):
return self._bar
@bar.setter
def bar(self, value):
self._bar = value
def __init__(self, dyn_property_name):
setattr(Foo, dyn_property_name, Foo.bar)
So now we can do stuff like:
>>> foo = Foo('baz')
>>> foo.baz = 5
>>> foo.bar
5
>>> foo.baz
5
BEWARE OF parse_requirements
BEHAVIOUR!
Please note that pip.req.parse_requirements
will change underscores to dashes. This was enraging me for a few days before I discovered it. Example demonstrating:
from pip.req import parse_requirements # tested with v.1.4.1
reqs = '''
example_with_underscores
example-with-dashes
'''
with open('requirements.txt', 'w') as f:
f.write(reqs)
req_deps = parse_requirements('requirements.txt')
result = [str(ir.req) for ir in req_deps if ir.req is not None]
print result
produces
['example-with-underscores', 'example-with-dashes']
You could filter the file through cat -n
before piping to less

you can read this tutorial for how to use functions of statistical distributions in python. http://docs.scipy.org/doc/scipy/reference/tutorial/stats.html
from scipy.stats import norm
import matplotlib.pyplot as plt
import numpy as np
#initialize a normal distribution with frozen in mean=-1, std. dev.= 1
rv = norm(loc = -1., scale = 1.0)
rv1 = norm(loc = 0., scale = 2.0)
rv2 = norm(loc = 2., scale = 3.0)
x = np.arange(-10, 10, .1)
#plot the pdfs of these normal distributions
plt.plot(x, rv.pdf(x), x, rv1.pdf(x), x, rv2.pdf(x))
Suspend the process with CTRL+Z then use the command bg
to resume it in background. For example:
sleep 60
^Z #Suspend character shown after hitting CTRL+Z
[1]+ Stopped sleep 60 #Message showing stopped process info
bg #Resume current job (last job stopped)
More about job control and bg
usage in bash
manual page:
JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.
EDIT
To start a process where you can even kill the terminal and it still carries on running
nohup [command] [-args] > [filename] 2>&1 &
e.g.
nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &
To just ignore the output (not very wise) change the filename to /dev/null
To get the error message set to a different file change the &1
to a filename.
In addition: You can use the jobs
command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1
or kill %2
with the number being the index of the process.
I adapted @shareef's answer to make it concise. I use,
.sort(function(arg1, arg2) { return arg1.length - arg2.length })
In Swift you can use the following code:
extension YourViewController: UIWebViewDelegate {
func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebView.NavigationType) -> Bool {
if let url = request.url, navigationType == UIWebView.NavigationType.linkClicked {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
return false
}
return true
}
}
Make sure you check for the URL value and the navigationType.
Python lists are mutable objects and here:
plot_data = [[]] * len(positions)
you are repeating the same list len(positions)
times.
>>> plot_data = [[]] * 3
>>> plot_data
[[], [], []]
>>> plot_data[0].append(1)
>>> plot_data
[[1], [1], [1]]
>>>
Each list in your list is a reference to the same object. You modify one, you see the modification in all of them.
If you want different lists, you can do this way:
plot_data = [[] for _ in positions]
for example:
>>> pd = [[] for _ in range(3)]
>>> pd
[[], [], []]
>>> pd[0].append(1)
>>> pd
[[1], [], []]
The -m
option is probably what you're looking for:
grep -m 10 PATTERN [FILE]
From man grep
:
-m NUM, --max-count=NUM
Stop reading a file after NUM matching lines. If the input is
standard input from a regular file, and NUM matching lines are
output, grep ensures that the standard input is positioned to
just after the last matching line before exiting, regardless of
the presence of trailing context lines. This enables a calling
process to resume a search.
Note: grep stops reading the file once the specified number of matches have been found!

For floating point data, you can use the new ismembertol
function, which computes set membership with a specified tolerance. This is similar to the ismemberf
function found in the File Exchange except that it is now built-in to MATLAB. Example:
>> pi_estimate = 3.14159;
>> abs(pi_estimate - pi)
ans =
5.3590e-08
>> tol = 1e-7;
>> ismembertol(pi,pi_estimate,tol)
ans =
1
One example of Haskell in action is xmonad, a "featureful window manager in less than 1200 lines of code".
Your query has 8 or possibly even 9 variables, ie. Name, Description etc. But the values, these things ---> '', '%s', '%s', '%s', '%s', '%s', '%s', '%s')"
, only total 7, the number of variables have to be the same as the values.
I had the same problem but I figured it out. Hopefully it will also work for you.
I have to say that you are taking on a lot in just 10 weeks, I just finished a semester of Java programming at Indiana University Southeast, and I don't think I have begun to scratch the surface yet. Java is a very strict language in that its syntax is very tough to get a handle on if you have no programming experience at all. I will offer these pieces of advice go to www.bluej.org and down load there, Java compiler it is said to be the easiest to work with and that most college's use this. It is also, what we learned on and from what I know now I can say, they are right. Java is an object oriented language, and Bluej gives you a great understanding of objects. They also show you how to design, classes, methods, array, array list, hash maps, all of that is on this site and it is free. I hope this helps and good luck with your challange.
The XPath spec. defines the string value of an element as the concatenation (in document order) of all of its text-node descendents.
This explains the "strange results".
"Better" results can be obtained using the expressions below:
//*[text() = 'qwerty']
The above selects every element in the document that has at least one text-node child with value 'qwerty'.
//*[text() = 'qwerty' and not(text()[2])]
The above selects every element in the document that has only one text-node child and its value is: 'qwerty'.
I believe you just migrated from C++, Well in java you have to initialize a data type(other then primitive types and String is not a considered as a primitive type in java ) to use them as according to their specifications if you don't then its just like an empty reference variable (much like a pointer in the context of C++).
public class StringTest {
public static void main(String[] args) {
String[] errorSoon = new String[100];
errorSoon[0] = "Error, why?";
//another approach would be direct initialization
String[] errorsoon = {"Error , why?"};
}
}
I looked at several of the options. Here are my two favorites, because I needed to round the value.

If you don't have an insert key, and you're using Visual Studio 2019, then double-clicking the OVR text in the bottom right corner does not work. You'll have to use an on-screen keyboard, if you have one of those, or figure out what your insert key is mapped to. For me, on my mac keyboard hooked up to windows 10, it is the 0 key on the keypad.
That's exactly why the "fuser -m /mount/point" exists.
BTW, I don't think "fuser" or "lsof" will indicate when a resource is held by kernel module, although I don't usually have that issue..

Cellpadding
is the amount of space between the outer edges of the
table cell and the content of the cell.
Cellspacing
is the amount of space in between the individual table cells.

awk is very cool, but why not keep it simple?
num=$(echo $var | grep -o "," | wc -l)
Solve the following equation system:
p = p0 + (p1 - p0) * s + (p2 - p0) * t
The point p
is inside the triangle if 0 <= s <= 1
and 0 <= t <= 1
and s + t <= 1
.
s
,t
and 1 - s - t
are called the barycentric coordinates of the point p
.
By CSS 2.1 rules, the height of a table cell is “the minimum height required by the content”. Thus, you need to restrict the height indirectly using inner markup, normally a div
element (<td><div>content</div></td>
), and set height
and overflow
properties on the the div
element (without setting display: table-cell
on it, of course, as that would make its height obey CSS 2.1 table cell rules).
Be careful when you are using one liner using sslKey or sslCert, as in Josh Peak's answer:
git clone -c http.sslCAPath="/path/to/selfCA" \
-c http.sslCAInfo="/path/to/selfCA/self-signed-certificate.crt" \
-c http.sslVerify=1 \
-c http.sslCert="/path/to/privatekey/myprivatecert.pem" \
-c http.sslCertPasswordProtected=0 \
https://mygit.server.com/projects/myproject.git myproject
Only Git 2.14.x/2.15 (Q3 2015) would be able to interpret a path like ~username/mykey
correctly (while it still can interpret an absolute path like /path/to/privatekey
).

to use the function from the beginning. Because of that, these variables all understand "~[username]/
" prefix.Make the remaining two variables,
http.sslcert
andhttp.sslkey
, also aware of the convention, as they are both clearly pathnames to files.
Command:

appends to the output.txt file, without replacing the content.
Yes, this behaviour is guaranteed:
The
@Before
methods of superclasses will be run before those of the current class, unless they are overridden in the current class. No other ordering is defined.
The
@After
methods declared in superclasses will be run after those of the current class, unless they are overridden in the current class.
To print the names of all files in and below $dir of size 0:
find "$dir" -size 0
Note that not all implementations of find
will produce output by default, so you may need to do:
find "$dir" -size 0 -print
Two comments on the final loop in the question:
Rather than iterating over every other word in a string and seeing if the alternate values are zero, you can partially eliminate the issue you're having with whitespace by iterating over lines. eg:
printf '1 f1\n0 f 2\n10 f3\n' | while read size path; do
test "$size" -eq 0 && echo "$path"; done
Note that this will fail in your case if any of the paths output by ls contain newlines, and this reinforces 2 points: don't parse ls
, and have a sane naming policy that doesn't allow whitespace in paths.
Secondly, to output the data from the loop, there is no need to store the output in a variable just to echo
it. If you simply let the loop write its output to stdout, you accomplish the same thing but avoid storing it.

A simple way to compare two string in c++ (tested for windows) is using _stricmp
// Case insensitive (could use equivalent _stricmp)
result = _stricmp( string1, string2 );
If you are looking to use with std::string, an example:
std::string s1 = string("Hello");
if ( _stricmp(s1.c_str(), "HELLO") == 0)
std::cout << "The string are equals.";

When deciding to use Array or ArrayList, your first instinct really shouldn't be worrying about performance, though they do perform differently. You first concern should be whether or not you know the size of the Array before hand. If you don't, naturally you would go with an array list, just for functionality.
Use the Where clause from LINQ:
List<object> x = new List<object>();
x.Add("A");
x.Add("B");
x.Add("C");
x.Add("D");
x.Add("B");
var z = x.Where(p => p == "A");
z = x.Where(p => p == "B");
In the statements above "p" is the object that is in the list. So if you used a data object, i.e.:
public class Client
{
public string Name { get; set; }
}
then your linq would look like this:
List<Client> x = new List<Client>();
x.Add(new Client() { Name = "A" });
x.Add(new Client() { Name = "B" });
x.Add(new Client() { Name = "C" });
x.Add(new Client() { Name = "D" });
x.Add(new Client() { Name = "B" });
var z = x.Where(p => p.Name == "A");
z = x.Where(p => p.Name == "B");

if you only want the last line deleted output without changing the file itself do
sed -e '$ d' foo.txt
if you want to delete the last line of the input file itself do
sed -i '' -e '$ d' foo.txt
The easiest way is to redirect the output of the echo
by >>
:
echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile
Big difference, TABLOCK
will try to grab "shared" locks, and TABLOCKX
exclusive locks.
If you are in a transaction and you grab an exclusive lock on a table, EG:
SELECT 1 FROM TABLE WITH (TABLOCKX)
No other processes will be able to grab any locks on the table, meaning all queries attempting to talk to the table will be blocked until the transaction commits.
TABLOCK
only grabs a shared lock, shared locks are released after a statement is executed if your transaction isolation is READ COMMITTED
(default). If your isolation level is higher, for example: SERIALIZABLE
, shared locks are held until the end of a transaction.
Shared locks are, hmmm, shared. Meaning 2 transactions can both read data from the table at the same time if they both hold a S or IS lock on the table (via TABLOCK
). However, if transaction A
holds a shared lock on a table, transaction B
will not be able to grab an exclusive lock until all shared locks are released. Read about which locks are compatible with which at msdn.
Both hints cause the db to bypass taking more granular locks (like row or page level locks). In principle, more granular locks allow you better concurrency. So for example, one transaction could be updating row 100 in your table and another row 1000, at the same time from two transactions (it gets tricky with page locks, but lets skip that).
In general granular locks is what you want, but sometimes you may want to reduce db concurrency to increase performance of a particular operation and eliminate the chance of deadlocks.
In general you would not use TABLOCK
or TABLOCKX
unless you absolutely needed it for some edge case.
At the point you are calling your function, the rest of the page has not rendered and so the element is not in existence at that point. Try calling your function on window.onload
maybe. Something like this:
<html>
<head>
<title></title>
<script type="text/javascript">
window.onload = function(){
var refButton = document.getElementById("btnButton");
refButton.onclick = function() {
alert('I am clicked!');
}
};
</script>
</head>
<body>
<form id="form1">
<div>
<input id="btnButton" type="button" value="Click me"/>
</div>
</form>
</body>
</html>
This is how it works for me.
Even faster alternative:
cat /dev/null > /var/lock/apache2/DAVlock
The compiler needs to know the size of the second dimension in your two dimensional array. For example:
void print_graph(g_node graph_node[], double weight[][5], int nodes);
While performance is an issue, I think modern database designs have made it much less of an issue for small files.
Performance aside, it also depends on just how tightly-coupled the data is. If the file contains data that is closely related to the fields of the database, then it conceptually belongs close to it and may be stored in a blob. If it contains information which could potentially relate to multiple records or may have some use outside of the context of the database, then it belongs outside. For example, an image on a web page is fetched on a separate request from the page that links to it, so it may belong outside (depending on the specific design and security considerations).
Our compromise, and I don't promise it's the best, has been to store smallish XML files in the database but images and other files outside it.
For a non ASP.NET control, i.e. HTML controls like div, table, td, tr
, etc. you need to first make them a server control, assign an ID, and then assign a property from server code:
<head>
<style type="text/css">
.top_rounded
{
height: 75px;
width: 75px;
border: 2px solid;
border-radius: 5px;
-moz-border-radius: 5px; /* Firefox 3.6 and earlier */
border-color: #9c1c1f;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div runat="server" id="myDiv">This is my div</div>
</form>
</body>
myDiv.Attributes.Add("class", "top_rounded");
string Output = Regex.Replace(Input, @"([ a-zA-Z0-9&, _]|^\s)", "");
Here all the special characters except space, comma, and ampersand are replaced. You can also omit space, comma and ampersand by the following regular expression.
string Output = Regex.Replace(Input, @"([ a-zA-Z0-9_]|^\s)", "");
Where Input is the string which we need to replace the characters.
If you have created a Java Project in eclipse by using the 'from existing source' option then it should work as it did before. To be more precise File > New Java Project. In the Contents section select 'Create project from existing source' and then select your existing project folder. The wizard will take care of the rest.
I think you want to config your database server firstly after the installation, as shown in picture, you can reconfigure MySql server
Now, is more easy with HTML 5 and CSS 3:
<!DOCTYPE html>

<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

My status bar and navigation bar overlap after return from landscape view of YTPlayer. Here is my solution after trying @comonitos' version but not work on my iOS 8
- (void)fixNavigationBarPosition {
if (self.navigationController) {
CGRect frame = self.navigationController.navigationBar.frame;
if (frame.origin.y != 20.f) {
frame.origin.y = 20.f;
self.navigationController.navigationBar.frame = frame;
}
}
}
Just call this function whenever you want to fix the position of navigation bar. I called on YTPlayerViewDelegate's playerView:didChangeToState:
- (void)playerView:(YTPlayerView *)playerView didChangeToState:(YTPlayerState)state {
switch (state) {
case kYTPlayerStatePaused:
case kYTPlayerStateEnded:
[self fixNavigationBarPosition];
break;
default:
}
}
Update: I'm doing this with date.toISOString().substr(0, 10)
. Gives the same result as the accepted answer and has good support.
.buttonDisabled{
background-color: unset !important;
color: unset !important;
}
You can check this way too
<c:if test="${theBooleanVariable ne true}">It's false!</c:if>
Try this using a previously mentioned regex:
String regex = "^([A-Za-z0-9+/]{4})*([A-Za-z0-9+/]{4}|[A-Za-z0-9+/]{3}=|[A-Za-z0-9+/]{2}==)$";
if("TXkgdGVzdCBzdHJpbmc/".matches(regex)){
System.out.println("it's a Base64");
}
...We can also make a simple validation like, if it has spaces it cannot be Base64:
String myString = "Hello World";
if(myString.contains(" ")){
System.out.println("Not B64");
}else{
System.out.println("Could be B64 encoded, since it has no spaces");
}
Just put the desired logic in the constructor of the request scoped bean associated with the JSF page.
public Bean() {
// Do your stuff here.
}
Use @PostConstruct
annotated method on a request or view scoped bean. It will be executed after construction and initialization/setting of all managed properties and injected dependencies.
@PostConstruct
public void init() {
// Do your stuff here.
}
This is strongly recommended over constructor in case you're using a bean management framework which uses proxies, such as CDI, because the constructor may not be called at the times you'd expect it.
Alternatively, use <f:event type="preRenderView">
in case you intend to initialize based on <f:viewParam>
too, or when the bean is put in a broader scope than the view scope (which in turn indicates a design problem, but that aside). Otherwise, a @PostConstruct
is perfectly fine too.
<f:metadata>
<f:viewParam name="foo" value="#{bean.foo}" />
<f:event type="preRenderView" listener="#{bean.onload}" />
</f:metadata>
public void onload() {
// Do your stuff here.
}
Alternatively, use <f:viewAction>
in case you intend to initialize based on <f:viewParam>
too, or when the bean is put in a broader scope than the view scope (which in turn indicates a design problem, but that aside). Otherwise, a @PostConstruct
is perfectly fine too.
<f:metadata>
<f:viewParam name="foo" value="#{bean.foo}" />
<f:viewAction action="#{bean.onload}" />
</f:metadata>
public void onload() {
// Do your stuff here.
}
Note that this can return a String
navigation case if necessary. It will be interpreted as a redirect (so you do not need a ?faces-redirect=true
here).
public String onload() {
// Do your stuff here.
// ...
return "some.xhtml";
}

to indent a ul
dropdown menu, use
/* Main Level */
ul{
margin-left:10px;
}
/* Second Level */
ul ul{
margin-left:15px;
}
/* Third Level */
ul ul ul{
margin-left:20px;
}
/* and so on... */
You can indent the li
s and (if applicable) the a
s (or whatever content elements you have) as well , each with differing effects.
You could also use padding-left
instead of margin-left
, again depending on the effect you want.
Update
By default, many browsers use padding-left
to set the initial indentation. If you want to get rid of that, set padding-left: 0px;
Still, both margin-left
and padding-left
settings impact the indentation of lists in different ways. Specifically: margin-left
impacts the indentation on the outside of the element's border, whereas padding-left
affects the spacing on the inside of the element's border. (Learn more about the CSS box model here)
Setting padding-left: 0;
leaves the li's bullet icons hanging over the edge of the element's border (at least in Chrome), which may or may not be what you want.
Examples of padding-left vs margin-left and how they can work together on ul: https://jsfiddle.net/daCrosby/bb7kj8cr/1/

No need for jQuery nor regex assuming the character you want to replace exists in the string
Replace last char in a string
str = str.substring(0,str.length-2)+otherchar
Replace last underscore in a string
var pos = str.lastIndexOf('_');
str = str.substring(0,pos) + otherchar + str.substring(pos+1)
or use one of the regular expressions from the other answers
var str1 = "Replace the full stop with a questionmark."_x000D_
var str2 = "Replace last _ with another char other than the underscore _ near the end"_x000D_
_x000D_
// Replace last char in a string_x000D_
_x000D_
console.log(_x000D_
str1.substring(0,str1.length-2)+"?"_x000D_
) _x000D_
// alternative syntax_x000D_
console.log(_x000D_
str1.slice(0,-1)+"?"_x000D_
)_x000D_
_x000D_
// Replace last underscore in a string _x000D_
_x000D_
var pos = str2.lastIndexOf('_'), otherchar = "|";_x000D_
console.log(_x000D_
str2.substring(0,pos) + otherchar + str2.substring(pos+1)_x000D_

As an example :
fourcc = cv2.VideoWriter_fourcc(*'MJPG')
out_corner = cv2.VideoWriter('img_corner_1.avi',fourcc, 20.0, (640, 480))
At that place, have to define X,Y as width and height
But, when you create an image (a blank image for instance) you have to define Y,X as height and width :
img_corner = np.zeros((480, 640, 3), np.uint8)
The easiest thing to do is to set the content type of your ajax request to "application/json; charset=utf-8"
and then let your API method consume JSON. Like this:
var basicInfo = JSON.stringify({
firstName: playerProfile.firstName(),
lastName: playerProfile.lastName(),
gender: playerProfile.gender(),
address: playerProfile.address(),
country: playerProfile.country(),
bio: playerProfile.bio()
});
$.ajax({
url: "http://localhost:8080/social/profile/update",
type: 'POST',
dataType: 'json',
contentType: "application/json; charset=utf-8",
data: basicInfo,
success: function(data) {
// ...
}
});
@RequestMapping(
value = "/profile/update",
method = RequestMethod.POST,
produces = MediaType.APPLICATION_JSON_VALUE,
consumes = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<ResponseModel> UpdateUserProfile(
@RequestBody User usersNewDetails,
HttpServletRequest request,
HttpServletResponse response
) {
// ...
}
I guess the problem is that Spring Boot has issues submitting form data which is not JSON via ajax request.
Note: the default content type for ajax is "application/x-www-form-urlencoded"
.
Additional Solution: use Restul api wrapper libraries written in Java
/ python
/ Ruby

Make sure you are loading those modules (myApp.services and myApp.directives) as dependencies of your main app module, like this:
angular.module('myApp', ['myApp.directives', 'myApp.services']);

I've done something like this.
private void Form_FormClosing(object sender, FormClosingEventArgs e)
{
if ((sender as Form).ActiveControl is Button)
{
//CloseButton
}
else
{
//The X has been clicked
}
}
You could write a method to print a 2d array like this:
//Displays a 2d array in the console, one line per row.
static void printMatrix(int[][] grid) {
for(int r=0; r<grid.length; r++) {
for(int c=0; c<grid[r].length; c++)
System.out.print(grid[r][c] + " ");
System.out.println();
}
}
clientX/Y refers to relative screen coordinates, for instance if your web-page is long enough then clientX/Y gives clicked point's coordinates location in terms of its actual pixel position while ScreenX/Y gives the ordinates in reference to start of page.
I do not remember from where I copied this function, but it looks like it is not listed and it is working for me
function rm_rf($path) {
if (@is_dir($path) && is_writable($path)) {
$dp = opendir($path);
while ($ent = readdir($dp)) {
if ($ent == '.' || $ent == '..') {
continue;
}
$file = $path . DIRECTORY_SEPARATOR . $ent;
if (@is_dir($file)) {
rm_rf($file);
} elseif (is_writable($file)) {
unlink($file);
} else {
echo $file . "is not writable and cannot be removed. Please fix the permission or select a new path.\n";
}
}
closedir($dp);
return rmdir($path);
} else {
return @unlink($path);
}
}
Use an infinite loop:
while True:
print('Hello world!')
This certainly can apply to your start()
function as well; you can exit the loop with either break
, or use return
to exit the function altogether, which also terminates the loop:
def start():
print ("Welcome to the converter toolkit made by Alan.")
while True:
op = input ("Please input what operation you wish to perform. 1 for Fahrenheit to Celsius, 2 for meters to centimetres and 3 for megabytes to gigabytes")
if op == "1":
f1 = input ("Please enter your fahrenheit temperature: ")
f1 = int(f1)
a1 = (f1 - 32) / 1.8
a1 = str(a1)
print (a1+" celsius")
elif op == "2":
m1 = input ("Please input your the amount of meters you wish to convert: ")
m1 = int(m1)
m2 = (m1 * 100)
m2 = str(m2)
print (m2+" m")
if op == "3":
mb1 = input ("Please input the amount of megabytes you want to convert")
mb1 = int(mb1)
mb2 = (mb1 / 1024)
mb3 = (mb2 / 1024)
mb3 = str(mb3)
print (mb3+" GB")
else:
print ("Sorry, that was an invalid command!")
If you were to add an option to quit as well, that could be:
if op.lower() in {'q', 'quit', 'e', 'exit'}:
print("Goodbye!")
return
for example.

Enumerable.SequenceEqual(FirstList.OrderBy(fElement => fElement),
SecondList.OrderBy(sElement => sElement))
I prefer the Underscore framework. It suggests many useful operations with objects. Your task:
var newArray = homes.filter(
price <= 1000 &
sqft >= 500 &
num_of_beds >=2 &
num_of_baths >= 2.5);
can be overwriten like:
var newArray = _.filter (homes, function(home) {
return home.price<=1000 && sqft>=500 && num_of_beds>=2 && num_of_baths>=2.5;
});
Hope it will be useful for you!
First, reset any changes
This will undo any changes you've made to tracked files and restore deleted files:
git reset HEAD --hard
Second, remove new files
This will delete any new files that were added since the last commit:
git clean -fd
Files that are not tracked due to .gitignore
are preserved; they will not be removed
Warning: using -x
instead of -fd
would delete ignored files. You probably don't want to do this.
Simply use the number pipe like so :
{{ numberValue | number : '.2-2'}}
The pipe above works as follows :
In "Attributes Inspector" of your Tab Bar Controller within Interface Builder make sure your Bottom Bar is set to Opaque Tab Bar:
Now goto your AppDelegate.m file. Find:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
And then add this code between the curly braces to change the colors of both the tab bar buttons and the tab bar background:
///----------------SET TAB BAR COLOR------------------------//
//--------------FOR TAB BAR BUTTON COLOR---------------//
[[UITabBar appearance] setTintColor:[UIColor greenColor]];
//-------------FOR TAB BAR BACKGROUND COLOR------------//
[[UITabBar appearance] setBarTintColor:[UIColor whiteColor]];
Let me tell you an annoying thing that happened with the N'
prefix - I wasn't able to fix it for two days.
My database collation is SQL_Latin1_General_CP1_CI_AS.
It has a table with a column called MyCol1. It is an Nvarchar
This query fails to match Exact Value That Exists.
SELECT TOP 1 * FROM myTable1 WHERE MyCol1 = 'ESKI'
// 0 result
using prefix N'' fixes it
SELECT TOP 1 * FROM myTable1 WHERE MyCol1 = N'ESKI'
// 1 result - found!!!!
Why? Because latin1_general doesn't have big dotted I that's why it fails I suppose.
For .NET 4.0 and higher, you can compare elements in array or tuples using the StructuralComparisons type:
object[] a1 = { "string", 123, true };
object[] a2 = { "string", 123, true };
Console.WriteLine (a1 == a2); // False (because arrays is reference types)
Console.WriteLine (a1.Equals (a2)); // False (because arrays is reference types)
IStructuralEquatable se1 = a1;
//Next returns True
Console.WriteLine (se1.Equals (a2, StructuralComparisons.StructuralEqualityComparer));
Did you try assigning it back to the column?
df['column'] = df['column'].astype('str')
Referring to this question, the pandas dataframe stores the pointers to the strings and hence it is of type 'object'. As per the docs ,You could try:
df['column_new'] = df['column'].str.split(',')
One can avoid the AttributeError
brought about by set_axis_labels()
method by using the matplotlib.pyplot.xlabel
and matplotlib.pyplot.ylabel
.
matplotlib.pyplot.xlabel
sets the x-axis label while the matplotlib.pyplot.ylabel
sets the y-axis label of the current axis.
Solution code:

import matplotlib.pyplot as plt
fake = pd.DataFrame({'cat': ['red', 'green', 'blue'], 'val': [1, 2, 3]})
fig = sns.barplot(x = 'val', y = 'cat', data = fake, color = 'black')

you could always do the next up front, and just do a post loop check
if (!resultSet.next() ) {
System.out.println("no data");
} else {
do {
//statement(s)
} while (resultSet.next());
}
I had the same issue, eventually I found a solution that works without splitting the file, by following Petter Ivarrson's answer
My problem was when converting .p12 certificate to .pem. I used:
openssl pkcs12 -in cert.p12 -out cert.pem
This converts and exports all certificates (CA + CLIENT) together with a private key into one file.
The problem was when I tried to verify if the hashes of certificate and key are matching by running:
// Get certificate HASH
openssl x509 -noout -modulus -in cert.pem | openssl md5
// Get private key HASH
openssl rsa -noout -modulus -in cert.pem | openssl md5
This displayed different hashes and that was the reason CURL failed. See here: https://michaelheap.com/curl-58-unable-to-set-private-key-file-server-key-type-pem/
I guess that was because all certificates are inside a file (CA + CLIENT) and CURL takes CA certificate instead of CLIENT one. Because CA is first in the list.
So the solution was to export only CLIENT certificate together with private key:
openssl pkcs12 -in cert.p12 -out cert.pem -clcerts
``
Now when I re-run the verification:
```sh
openssl x509 -noout -modulus -in cert.pem | openssl md5
openssl rsa -noout -modulus -in cert.pem | openssl md5
HASHES MATCHED !!!
So I was able to make a curl request by running
curl -ivk --cert ./cert.pem:KeyChoosenByMeWhenIrunOpenSSL https://thesite.com
without problems!!!
That being said... I think the best solution is to split the certificates into separate file and use them separately like Petter Ivarsson wrote:
curl --insecure --key key.pem --cacert ca.pem --cert client.pem:KeyChoosenByMeWhenIrunOpenSSL https://thesite.com
Yes its possible to pass JSON object in URL
queryString = "{\"left\":\"" + params.get("left") + "}";
httpRestTemplate.exchange(
Endpoint + "/A/B?query={queryString}",
HttpMethod.GET, entity, z.class, queryString);
We setup wildcard DNS like they explained above. So the a record is *.yourname.com
Then all of the subdomains are actually going to the same place, but PHP treats each subdomain as a different account.
We use the following code:
$url=$_SERVER["REQUEST_URI"];
$account=str_replace(".yourdomain.com","",$url);
This code just sets the $account
variable the same as the subdomain. You could then retrieve their files and other information based on their account.
This probably isn't as efficient as the ways they list above, but if you don't have access to BIND and/or limited .htaccess this method should work (as long as your host will setup the wildcard for you).
We actually use this method to connect to the customers database for a multi-company e-commerce application, but it may work for you as well.
Just for the sake of academic interest, I did it this way...
(dt.replace(month = dt.month % 12 +1, day = 1)-timedelta(days=1)).day
A bare repository has benefits in
In my case, the function CString was not found. But adding an empty string to the value works, too.
Dim Test As Integer, Test2 As Variant
Test = 10
Test2 = Test & ""
//Test2 is now "10" not 10
This also works:
var number = 12354987;_x000D_
console.log(String(number).split('').map(Number));
_x000D_
No need to find
. If you are just looking for a pattern within a specific directory, this should suffice:
grep -hn FOO /your/path/*.bar
Where -h
is the parameter to hide the filename, as from man grep
:
-h, --no-filename
Suppress the prefixing of file names on output. This is the default when there is only one file (or only standard input) to search.
Note that you were using
-H, --with-filename
Print the file name for each match. This is the default when there is more than one file to search.
If you end up with merge conflict and doesn't have anything to commit, but still a merge error is being displayed. After applying all the below mentioned commands,
git reset --hard HEAD
git pull --strategy=theirs remote_branch
git fetch origin
git reset --hard origin
Please remove
.git\index.lock
File [cut paste to some other location in case of recovery] and then enter any of below command depending on which version you want.
git reset --hard HEAD
git reset --hard origin
Hope that helps!!!
Starting with C# 8.0, you can use the ??= operator to replace the code of the form
if (variable is null)
{
variable = expression;
}
with the following code:
variable ??= expression;

Create a new class MyView, Which extends View
. Override the onDraw(Canvas canvas)
method to draw rectangle on Canvas
.
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Path;
import android.util.AttributeSet;
import android.view.View;
public class MyView extends View {
Paint paint;
Path path;
public MyView(Context context) {
super(context);
init();
}
public MyView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public MyView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
private void init(){
paint = new Paint();
paint.setColor(Color.BLUE);
paint.setStrokeWidth(10);
paint.setStyle(Paint.Style.STROKE);
}
@Override
protected void onDraw(Canvas canvas) {
// TODO Auto-generated method stub
super.onDraw(canvas);
canvas.drawRect(30, 50, 200, 350, paint);
canvas.drawRect(100, 100, 300, 400, paint);
//drawRect(left, top, right, bottom, paint)
}
}
Then Move your Java activity to setContentView()
using our custom View, MyView.Call this way.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new MyView(this));
}
For more details you can visit here

They do behave differently when the value
is null
.
null.toString()
throws an error - Cannot call method 'toString' of nullString(null)
returns - "null"null + ""
also returns - "null"Very similar behaviour happens if value
is undefined
(see jbabey's answer).
Other than that, there is a negligible performance difference, which, unless you're using them in huge loops, isn't worth worrying about.
I was so exasperated by many misleading articles and answers that I wrote my own RSS reader: https://gouessej.wordpress.com/2020/06/28/comment-creer-un-lecteur-rss-en-javascript-how-to-create-a-rss-reader-in-javascript/
You can use AJAX requests to fetch the RSS files but it will work if and only if you use a CORS proxy. I'll try to write my own CORS proxy to give you a more robust solution. In the meantime, it works, I deployed it on my server under Debian Linux.
My solution doesn't use JQuery, I use only plain Javascript standard APIs with no third party libraries and it's supposed to work even with Microsoft Internet Explorer 11.
Dont use spaces:
SET @var="GREG"
::instead of SET @var = "GREG"
ECHO %@var%
PAUSE
As others have said, usually you want to use hg backout
or git revert
. However, sometimes you really want to get rid of a commit.
First, you'll want to go to your repository's settings. Click on the Strip commits
link.
Enter the changeset ID for the changeset you want to destroy, and click Preview strip
. That will let you see what kind of damage you're about to do before you do it. Then just click Confirm
and your commit is no longer history. Make sure you tell all your collaborators what you've done, so they don't accidentally push the offending commit back.
Image shown below. I'm only typing this because of a 30 character minimum imposed by Stackoverflow.
to allow letters ans spaces
jQuery.validator.addMethod("lettersonly", function(value, element) {
return this.optional(element) || /^[a-z\s]+$/i.test(value);
}, "Only alphabetical characters");
$('#yourform').validate({
rules: {
name_field: {
lettersonly: true
}
}
});
You can do this dynamically - in case you encounter not only: HH:mm:ss, but also, mm:ss, or even ss alone.
var str = '12:99:07';
var times = str.split(":");
times.reverse();
var x = times.length, y = 0, z;
for (var i = 0; i < x; i++) {
z = times[i] * Math.pow(60, i);
y += z;
}
console.log(y);
Open the project's properties---> Java Build Path ---> Libraries tab ---> Add External Jars
will allow you to add jars.
You need to download commonsIO from here.
First of all use
mysqli_connect($dbhost,$dbuser,$dbpass,$dbname)
Second - put mysqli_
everywhere instead of mysql_
Third - use this
$sql = "UPDATE anstalld SET mandag = '.$mandag.', tisdag = '.$tisdag.', onsdag = '.$onsdag.', torsdag = '.$torsdag.', fredag = '.$fredag.' WHERE namn = '.$namn.'";
$retval = mysqli_query( $conn, $sql ); //execute your query
if Your data is being updated in your database but not in your table its because when you will click on update button, the request is made to the same file. It first selects the data from the database when it is not updated prints it in the table and then update it according to the flow. If you have to update it as you click on update button then put this section
<?php
if(isset($_POST['update']))
{
$namn = $_POST['namnid'];
$mandag = $_POST['mandagid'];
$tisdag = $_POST['tisdagid'];
$onsdag = $_POST['onsdagid'];
$torsdag = $_POST['torsdagid'];
$fredag = $_POST['fredagid'];
$sql = mysql_query("UPDATE anstalld SET mandag = '$mandag', tisdag = '$tisdag', onsdag = '$onsdag', torsdag = '$torsdag', fredag = '$fredag' WHERE namn = '$namn'");
$retval = mysql_query( $sql, $conn );
if(! $retval )
{
die('Could not update data: ' . mysql_error());
}
echo "Updated data successfully\n";
}
?>`
after connecting with database.
