This question has been addressed, in a slightly different form, at length, here:
But this addresses it from the server-side. Let's look at this from the client-side. Before we do that, though, there's an important prelude:
Matasano's article on this is famous, but the lessons contained therein are pretty important:
To summarize:
<script>
function hash_algorithm(password){ lol_nope_send_it_to_me_instead(password); }</script>
And to add a corollary of my own:
This renders a lot of RESTful authentication schemes impossible or silly if you're intending to use a JavaScript client. Let's look!
First and foremost, HTTP Basic Auth. The simplest of schemes: simply pass a name and password with every request.
This, of course, absolutely requires SSL, because you're passing a Base64 (reversibly) encoded name and password with every request. Anybody listening on the line could extract username and password trivially. Most of the "Basic Auth is insecure" arguments come from a place of "Basic Auth over HTTP" which is an awful idea.
The browser provides baked-in HTTP Basic Auth support, but it is ugly as sin and you probably shouldn't use it for your app. The alternative, though, is to stash username and password in JavaScript.
This is the most RESTful solution. The server requires no knowledge of state whatsoever and authenticates every individual interaction with the user. Some REST enthusiasts (mostly strawmen) insist that maintaining any sort of state is heresy and will froth at the mouth if you think of any other authentication method. There are theoretical benefits to this sort of standards-compliance - it's supported by Apache out of the box - you could store your objects as files in folders protected by .htaccess files if your heart desired!
The problem? You are caching on the client-side a username and password. This gives evil.ru a better crack at it - even the most basic of XSS vulnerabilities could result in the client beaming his username and password to an evil server. You could try to alleviate this risk by hashing and salting the password, but remember: JavaScript Crypto is Hopeless. You could alleviate this risk by leaving it up to the Browser's Basic Auth support, but.. ugly as sin, as mentioned earlier.
Is Digest authentication possible with jQuery?
A more "secure" auth, this is a request/response hash challenge. Except JavaScript Crypto is Hopeless, so it only works over SSL and you still have to cache the username and password on the client side, making it more complicated than HTTP Basic Auth but no more secure.
Another more "secure" auth, where you encrypt your parameters with nonce and timing data (to protect against repeat and timing attacks) and send the. One of the best examples of this is the OAuth 1.0 protocol, which is, as far as I know, a pretty stonking way to implement authentication on a REST server.
http://tools.ietf.org/html/rfc5849
Oh, but there aren't any OAuth 1.0 clients for JavaScript. Why?
JavaScript Crypto is Hopeless, remember. JavaScript can't participate in OAuth 1.0 without SSL, and you still have to store the client's username and password locally - which puts this in the same category as Digest Auth - it's more complicated than HTTP Basic Auth but it's no more secure.
The user sends a username and password, and in exchange gets a token that can be used to authenticate requests.
This is marginally more secure than HTTP Basic Auth, because as soon as the username/password transaction is complete you can discard the sensitive data. It's also less RESTful, as tokens constitute "state" and make the server implementation more complicated.
The rub though, is that you still have to send that initial username and password to get a token. Sensitive information still touches your compromisable JavaScript.
To protect your user's credentials, you still need to keep attackers out of your JavaScript, and you still need to send a username and password over the wire. SSL Required.
It's common to enforce token policies like "hey, when this token has been around too long, discard it and make the user authenticate again." or "I'm pretty sure that the only IP address allowed to use this token is XXX.XXX.XXX.XXX
". Many of these policies are pretty good ideas.
However, using a token Without SSL is still vulnerable to an attack called 'sidejacking': http://codebutler.github.io/firesheep/
The attacker doesn't get your user's credentials, but they can still pretend to be your user, which can be pretty bad.
tl;dr: Sending unencrypted tokens over the wire means that attackers can easily nab those tokens and pretend to be your user. FireSheep is a program that makes this very easy.
The larger the application that you're running, the harder it is to absolutely ensure that they won't be able to inject some code that changes how you process sensitive data. Do you absolutely trust your CDN? Your advertisers? Your own code base?
Common for credit card details and less common for username and password - some implementers keep 'sensitive data entry' on a separate page from the rest of their application, a page that can be tightly controlled and locked down as best as possible, preferably one that is difficult to phish users with.
It is possible (and common) to put the authentication token in a cookie. This doesn't change any of the properties of auth with the token, it's more of a convenience thing. All of the previous arguments still apply.
Session Auth is just Token authentication, but with a few differences that make it seem like a slightly different thing:
Aside from that, though, it's no different from Token Auth, really.
This wanders even further from a RESTful implementation - with state objects you're going further and further down the path of plain ol' RPC on a stateful server.
OAuth 2.0 looks at the problem of "How does Software A give Software B access to User X's data without Software B having access to User X's login credentials."
The implementation is very much just a standard way for a user to get a token, and then for a third party service to go "yep, this user and this token match, and you can get some of their data from us now."
Fundamentally, though, OAuth 2.0 is just a token protocol. It exhibits the same properties as other token protocols - you still need SSL to protect those tokens - it just changes up how those tokens are generated.
There are two ways that OAuth 2.0 can help you:
But when it comes down to it, you're just... using tokens.
So, the question that you're asking is "should I store my token in a cookie and have my environment's automatic session management take care of the details, or should I store my token in Javascript and handle those details myself?"
And the answer is: do whatever makes you happy.
The thing about automatic session management, though, is that there's a lot of magic happening behind the scenes for you. Often it's nicer to be in control of those details yourself.
The other answer is: Use https for everything or brigands will steal your users' passwords and tokens.
I think you will find that if your web app is performing a complex operation then provided feedback is given to the user, they won't mind (too much).
For example: Loading Google Mail.
export const a = 1;
export const b = 2;
export const c = 3;
This will work w/ Babel transforms today and should take advantage of all the benefits of ES2016 modules whenever that feature actually lands in a browser.
You can also add export default {a, b, c};
which will allow you to import all the values as an object w/o the * as
, i.e. import myModule from 'my-module';
Sources:
Assuming that you have a DHCP server running at your router I would use:
# /etc/network/interfaces
auto lo eth0
iface lo inet loopback
iface eth0 inet dhcp
After changing the file issue (as root):
/etc/init.d/networking restart
You can change the level to OFF which should get rid of all logging. According to the log4j website, valid levels in order of importance are TRACE, DEBUG, INFO, WARN, ERROR, FATAL. There is one undocumented level called OFF which is a higher level than FATAL, and turns off all logging.
You can also create an extra root logger to log nothing (level OFF), so that you can switch root loggers easily. Here's a post to get you started on that.
You might also want to read the Log4J FAQ, because I think turning off all logging may not help. It will certainly not speed up your app that much, because logging code is executed anyway, up to the point where log4j decides that it doesn't need to log this entry.
In case you don't want to get mad with spaces in arguments and want to use variables try this:
objshell.run "cscript ""99 Writelog.vbs"" /r:" & r & " /f:""" & wscript.scriptname & """ /c:""" & c & ""
where
r=123
c="Whatever comment you like"
Is there a command that does?
thread apply all where
> and <
is a character entity reference for the >
and <
character in HTML.
It is not possible to use the less than (<) or greater than (>) signs in your file, because the browser will mix them with tags.
for these difficulties you can use entity names(>
) and entity numbers(<
).
In my case it was solved just passing proxy to connection. Thanks to @Andreas Panagiotidis.
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("<YOUR.HOST>", 80)));
HttpsURLConnection con = (HttpsURLConnection) url.openConnection(proxy);
I put some animated gif in a form called FormWait
and then I called it as:
// show the form
new Thread(() => new FormWait().ShowDialog()).Start();
// do the heavy stuff here
// get the form reference back and close it
FormWait f = new FormWait();
f = (FormWait)Application.OpenForms["FormWait"];
f.Close();
You can make use of $parsers as shown below,this solved it for me.
window.module.directive('myDate', function(dateFilter) {
return {
restrict: 'EAC',
require: '?ngModel',
link: function(scope, element, attrs, ngModel) {
ngModel.$parsers.push(function(viewValue) {
return dateFilter(viewValue,'yyyy-MM-dd');
});
}
};
});
HTML:
<p class="input-group datepicker" >
<input
type="text"
class="form-control"
name="name"
datepicker-popup="yyyy-MM-dd"
date-type="string"
show-weeks="false"
ng-model="data[$parent.editable.name]"
is-open="$parent.opened"
min-date="minDate"
close-text="Close"
ng-required="{{editable.mandatory}}"
show-button-bar="false"
close-on-date-selection="false"
my-date />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="openDatePicker($event)">
<i class="glyphicon glyphicon-calendar"></i>
</button>
</span>
</p>
If you run your playbook with ansible-playbook -vvv
you'll see the actual command being run, so you can check whether the key is actually being included in the ssh command (and you might discover that the problem was the wrong username rather than the missing key).
I agree with Brian's comment above (and zigam's edit) that the vars section is too late. I also tested including the key in the on-the-fly definition of the host like this
# fails
- name: Add all instance public IPs to host group
add_host: hostname={{ item.public_ip }} groups=ec2hosts ansible_ssh_private_key_file=~/.aws/dev_staging.pem
loop: "{{ ec2.instances }}"
but that fails too.
So this is not an answer. Just some debugging help and things not to try.
I was facing the same problem when I'm trying to connecting Mysql database using the Laravel application. I would like to recommend please check the password for the user. MySQL password should not have special characters like #, &, etc...
Reading this article I noticed great benefits using Guard
Here you can compare the use of guard with an example:
This is the part without guard:
func fooBinding(x: Int?) {
if let x = x where x > 0 {
// Do stuff with x
x.description
}
// Value requirements not met, do something
}
Here you’re putting your desired code within all the conditions
You might not immediately see a problem with this, but you could imagine how confusing it could become if it was nested with numerous conditions that all needed to be met before running your statements
The way to clean this up is to do each of your checks first, and exit if any aren’t met. This allows easy understanding of what conditions will make this function exit.
But now we can use guard and we can see that is possible to resolve some issues:
func fooGuard(x: Int?) {
guard let x = x where x > 0 else {
// Value requirements not met, do something
return
}
// Do stuff with x
x.description
}
- Checking for the condition you do want, not the one you don’t. This again is similar to an assert. If the condition is not met, guard‘s else statement is run, which breaks out of the function.
- If the condition passes, the optional variable here is automatically unwrapped for you within the scope that the guard statement was called – in this case, the fooGuard(_:) function.
- You are checking for bad cases early, making your function more readable and easier to maintain
This same pattern holds true for non-optional values as well:
func fooNonOptionalGood(x: Int) {
guard x > 0 else {
// Value requirements not met, do something
return
}
// Do stuff with x
}
func fooNonOptionalBad(x: Int) {
if x <= 0 {
// Value requirements not met, do something
return
}
// Do stuff with x
}
If you still have any questions you can read the entire article: Swift guard statement.
Wrapping Up
And finally, reading and testing I found that if you use guard to unwrap any optionals,
those unwrapped values stay around for you to use in the rest of your code block
.
guard let unwrappedName = userName else {
return
}
print("Your username is \(unwrappedName)")
Here the unwrapped value would be available only inside the if block
if let unwrappedName = userName {
print("Your username is \(unwrappedName)")
} else {
return
}
// this won't work – unwrappedName doesn't exist here!
print("Your username is \(unwrappedName)")

PHP coders may want to check out implode(). This takes an array joins it up using a string.
From the docs...
$array = array('lastname', 'email', 'phone');
echo implode(",", $array); // lastname,email,phone
you can return 2 or more values to a function in VBA or any other visual basic stuff but you need to use the pointer method called Byref. See my example below. I will make a function to add and subtract 2 values say 5,6
sub Macro1
' now you call the function this way
dim o1 as integer, o2 as integer
AddSubtract 5, 6, o1, o2
msgbox o2
msgbox o1
end sub
function AddSubtract(a as integer, b as integer, ByRef sum as integer, ByRef dif as integer)
sum = a + b
dif = b - 1
end function

OSX's Python binary (version 2) is located at /usr/bin/python
if you use which python
it will tell you where the python
command is being resolved to. Typically, what happens is third parties redefine things in /usr/local/bin
(which takes precedence, by default over /usr/bin
). To fix, you can either run /usr/bin/python
directly to use 2.x or find the errant redefinition (probably in /usr/local/bin
or somewhere else in your PATH
)
I solved this issue by install adb package. I'm using Ubuntu.
sudo apt install adb

I had the same problem: I love the resolve
object, but that only works for the content of ng-view. What if you have controllers (for top-level nav, let's say) that exist outside of ng-view and which need to be initialized with data before the routing even begins to happen? How do we avoid mucking around on the server-side just to make that work?
Use manual bootstrap and an angular constant. A naiive XHR gets you your data, and you bootstrap angular in its callback, which deals with your async issues. In the example below, you don't even need to create a global variable. The returned data exists only in angular scope as an injectable, and isn't even present inside of controllers, services, etc. unless you inject it. (Much as you would inject the output of your resolve
object into the controller for a routed view.) If you prefer to thereafter interact with that data as a service, you can create a service, inject the data, and nobody will ever be the wiser.
Example:
//First, we have to create the angular module, because all the other JS files are going to load while we're getting data and bootstrapping, and they need to be able to attach to it.
var MyApp = angular.module('MyApp', ['dependency1', 'dependency2']);
// Use angular's version of document.ready() just to make extra-sure DOM is fully
// loaded before you bootstrap. This is probably optional, given that the async
// data call will probably take significantly longer than DOM load. YMMV.
// Has the added virtue of keeping your XHR junk out of global scope.
angular.element(document).ready(function() {
//first, we create the callback that will fire after the data is down
function xhrCallback() {
var myData = this.responseText; // the XHR output
// here's where we attach a constant containing the API data to our app
// module. Don't forget to parse JSON, which `$http` normally does for you.
MyApp.constant('NavData', JSON.parse(myData));
// now, perform any other final configuration of your angular module.
MyApp.config(['$routeProvider', function ($routeProvider) {
$routeProvider
.when('/someroute', {configs})
.otherwise({redirectTo: '/someroute'});
}]);
// And last, bootstrap the app. Be sure to remove `ng-app` from your index.html.
angular.bootstrap(document, ['NYSP']);
};
//here, the basic mechanics of the XHR, which you can customize.
var oReq = new XMLHttpRequest();
oReq.onload = xhrCallback;
oReq.open("get", "/api/overview", true); // your specific API URL
oReq.send();
})
Now, your NavData
constant exists. Go ahead and inject it into a controller or service:
angular.module('MyApp')
.controller('NavCtrl', ['NavData', function (NavData) {
$scope.localObject = NavData; //now it's addressable in your templates
}]);
Of course, using a bare XHR object strips away a number of the niceties that $http
or JQuery would take care of for you, but this example works with no special dependencies, at least for a simple get
. If you want a little more power for your request, load up an external library to help you out. But I don't think it's possible to access angular's $http
or other tools in this context.

Got the error (in the function init) with the following code ;
"use strict" ;
var hdr ;
function init(){ // called on load
hdr = document.getElementById("hdr");
}
... while using the stock browser on a Samsung galaxy Fame ( crap phone which makes it a good tester ) - userAgent ; Mozilla/5.0 (Linux; U; Android 4.1.2; en-gb; GT-S6810P Build/JZO54K) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30
The same code works everywhere else I tried including the stock browser on an older HTC phone - userAgent ; Mozilla/5.0 (Linux; U; Android 2.3.5; en-gb; HTC_WildfireS_A510e Build/GRJ90) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1
The fix for this was to change
var hdr ;
to
var hdr = null ;
Nicest solution that I was able to figure out was with bluebird
promises. You can just do Promise.resolve(files).each(fs.readFileAsync);
which guarantees that promises are resolved sequentially in order.
this worked for me:
ProxyRequests Off
ProxyPreserveHost On
RewriteEngine On
<Proxy http://localhost:8123>
Order deny,allow
Allow from all
</Proxy>
ProxyPass /node http://localhost:8123
ProxyPassReverse /node http://localhost:8123
NOTICE: Command php bin/console generate:doctrine:crud
also create TestController
in src/Tests
so it can throw error when you tried to start server if you don't have UnitTests
. Remove the file fix it!
Have you tried:
db.posts.find({"created_on": {"$gte": new Date(2012, 7, 14), "$lt": new Date(2012, 7, 15)}})
The problem you're going to run into is that dates are stored as timestamps in Mongo. So, to match a date you're asking it to match a timestamp. In your case I think you're trying to match a day (ie. from 00:00 to 23:59 on a specific date). If your dates are stored without times then you should be okay. Otherwise, try specifying your date as a range of time on the same day (ie. start=00:00, end=23:59) if gte doesn't work.
Sometimes, the same error occurs when you forget to include the corresponding header
.
You can't do it the way you've written it because C++ class member functions have a hidden this
parameter passed in. pthread_create()
has no idea what value of this
to use, so if you try to get around the compiler by casting the method to a function pointer of the appropriate type, you'll get a segmetnation fault. You have to use a static class method (which has no this
parameter), or a plain ordinary function to bootstrap the class:
class C
{
public:
void *hello(void)
{
std::cout << "Hello, world!" << std::endl;
return 0;
}
static void *hello_helper(void *context)
{
return ((C *)context)->hello();
}
};
...
C c;
pthread_t t;
pthread_create(&t, NULL, &C::hello_helper, &c);
I've spend a large part of my day looking into this P3P thing and I feel the need to share what I've found out.
I've noticed that the P3P concept is very outdated and seems only to be really used/enforced by Internet Explorer (IE).
The simplest explanation is: IE wants you to define a P3P header if you are using cookies.
This is a nice idea, and luckily most of the time not providing this header won't cause any issues (read browser warnings). Unless your website/web application is loaded into an other website using an (i)Frame. This is where IE becomes a massive pain in the ***. It will not allow you to set a cookie unless the P3P header is set.
Knowing this I wanted to find an answer to the following two questions:
My findings are:
The concept was born in 2002 and it baffles me that this outdated and legally unimplemented concept is still forced upon developers within IE. If this header doesn't have have any legal ramifications this header should be ignored (or alternatively, generate a warning or notification in the console). Not enforced! I'm now forced to put a line in my code (and send a header to the client) that does absolutely nothing.
In short - to keep IE happy - add the following line to your PHP code (Other languages should look similar)
header('P3P: CP="Potato"');
Problem solved, and IE is happy with this potato.
"Not equals" can be expressed with the "not" operator !
and the standard .equals
.
if (a.equals(b)) // a equals b
if (!a.equals(b)) // a not equal to b
Another solution is changing the api level of your project in build.gradle and this will work.
If you need to pass data from one controller to another you must pass data by route values.Because both are different request.if you send data from one page to another then you have to user query string(same as route values).
But you can do one trick :
In your calling action call the called action as a simple method :
public class ServerController : Controller
{
[HttpPost]
public ActionResult ApplicationPoolsUpdate(ServiceViewModel viewModel)
{
XDocument updatedResultsDocument = myService.UpdateApplicationPools();
ApplicationPoolController pool=new ApplicationPoolController(); //make an object of ApplicationPoolController class.
return pool.UpdateConfirmation(updatedResultsDocument); // call the ActionMethod you want as a simple method and pass the model as an argument.
// Redirect to ApplicationPool controller and pass
// updatedResultsDocument to be used in UpdateConfirmation action method
}
}
<ComboBox Text="Something">
<ComboBoxItem Content="Item1"></ComboBoxItem >
<ComboBoxItem Content="Item2"></ComboBoxItem >
<ComboBoxItem Content="Item3"></ComboBoxItem >

To simply explain the difference,
response.sendRedirect("login.jsp");
doesn't prepend the contextpath (refers to the application/module in which the servlet is bundled)
but, whereas
request.getRequestDispathcer("login.jsp").forward(request, response);
will prepend the contextpath of the respective application
Furthermore, Redirect request is used to redirect to resources to different servers or domains. This transfer of control task is delegated to the browser by the container. That is, the redirect sends a header back to the browser / client. This header contains the resource url to be redirected by the browser. Then the browser initiates a new request to the given url.
Forward request is used to forward to resources available within the server from where the call is made. This transfer of control is done by the container internally and browser / client is not involved.
Excerpt from http://www.mingw.org/wiki/FAQ:
What's the difference between make and mingw32-make?
The "native" (i.e.: MSVCRT dependent) port of make is lacking in some functionality and has modified functionality due to the lack of POSIX on Win32. There also exists a version of make in the MSYS distribution that is dependent on the MSYS runtime. This port operates more as make was intended to operate and gives less headaches during execution. Based on this, the MinGW developers/maintainers/packagers decided it would be best to rename the native version so that both the "native" version and the MSYS version could be present at the same time without file name collision.
So,look into C:\MinGW\bin directory and first make sure what make executable, have you installed.(make.exe or mingw32-make.exe)
Before using MinGW, you should add C:\MinGW\bin; to the PATH environment variable using the instructions mentioned at http://www.mingw.org/wiki/Getting_Started/
Then cd to your directory, where you have the makefile and Try using mingw32-make.exe makefile.in
or simply make.exe makefile.in
(depending on executables in C:\MinGW\bin).
If you want a GUI based solution, install DevCPP IDE and then re-make.
In raw javascript, you'll want to put an id on your anchor tag and do this:
<html>
<script>
var simpleText = "hello_world";
var finalSplitText = simpleText.split("_");
var splitText = finalSplitText[0];
function insertText(){
document.getElementById('someId').InnerHTML = splitText;}
</script>
<body onload="insertText()">
<a href = test.html id="someId">I need the value of "splitText" variable here</a>
</body>
</html>
Regexp solution:
ref = ref.replace(/^F0/, "");
plain solution:
if (ref.substr(0, 2) == "F0")
ref = ref.substr(2);
use inline-block
instead of inline
. Read more information here about the difference between inline and inline-block.
.inline {
display: inline-block;
border: 1px solid red;
margin:10px;
}
An easy way to do:
function toggleButton(ref,bttnID){
document.getElementById(bttnID).disabled= ((ref.value !== ref.defaultValue) ? false : true);
}
<input ... onkeyup="toggleButton(this,'bttnsubmit');">
<input ... disabled='disabled' id='bttnsubmit' ... >
You need to install the Visual C++ libraries: http://www.microsoft.com/en-us/download/details.aspx?id=30679
As mentioned by Stuart McLaughlin, make sure you get the x86 version even if you use a 64-bits OS because PHP needs some 32-bit libraries.
In AngularJS, we update our models, and our views/templates update the DOM "automatically" (via built-in or custom directives).
$apply and $watch, both being Scope methods, are not related to the DOM.
The Concepts page (section "Runtime") has a pretty good explanation of the $digest loop, $apply, the $evalAsync queue and the $watch list. Here's the picture that accompanies the text:
Whatever code has access to a scope – normally controllers and directives (their link functions and/or their controllers) – can set up a "watchExpression" that AngularJS will evaluate against that scope. This evaluation happens whenever AngularJS enters its $digest loop (in particular, the "$watch list" loop). You can watch individual scope properties, you can define a function to watch two properties together, you can watch the length of an array, etc.
When things happen "inside AngularJS" – e.g., you type into a textbox that has AngularJS two-way databinding enabled (i.e., uses ng-model), an $http callback fires, etc. – $apply has already been called, so we're inside the "AngularJS" rectangle in the figure above. All watchExpressions will be evaluated (possibly more than once – until no further changes are detected).
When things happen "outside AngularJS" – e.g., you used bind() in a directive and then that event fires, resulting in your callback being called, or some jQuery registered callback fires – we're still in the "Native" rectangle. If the callback code modifies anything that any $watch is watching, call $apply to get into the AngularJS rectangle, causing the $digest loop to run, and hence AngularJS will notice the change and do its magic.

Add webpack command as an npm script in your package.json.
{
"name": "react-app",
"version": "1.0.0",
"scripts": {
"compile": "webpack --config webpack.config.js"
}
}
Then run
npm run compile
When the webpack is installed it creates a binary in ./node_modules/.bin folder. npm scripts also looks for executable created in this folder
ERRORLEVEL
will contain the return code of the last command. Sadly you can only check >=
for it.
Note specifically this line in the MSDN documentation for the If
statement:
errorlevel Number
Specifies a true condition only if the previous program run by Cmd.exe returned an exit code equal to or greater than Number.
So to check for 0 you need to think outside the box:
IF ERRORLEVEL 1 GOTO errorHandling
REM no error here, errolevel == 0
:errorHandling
Or if you want to code error handling first:
IF NOT ERRORLEVEL 1 GOTO no_error
REM errorhandling, errorlevel >= 1
:no_error

With splitext there are problems with files with double extension (e.g. file.tar.gz
, file.tar.bz2
, etc..)
>>> fileName, fileExtension = os.path.splitext('/path/to/somefile.tar.gz')
>>> fileExtension
'.gz'
but should be: .tar.gz
The possible solutions are here
COLUMN()
and ROW()
won't work this way because they are applied to the cell that is calling them. In conditional formatting, you will have to be explicit instead of implicit.
For instance, if you want to use this conditional formating on a range begining on cell A1
, you can try:
`COLUMN(A1)` and `ROW(A1)`
Excel will automatically adapt the conditional formating to the current cell.
flup's answer is the best but it did not work for me completely. I had to do the following as well to get it working:
export JAVA_HOME=/usr/lib/jvm/java-7-oracle/jre/
chmod 777

- Building HibernateBuilding on the examples above I thought I'd throw in a way of transparently binding a controller variable to a service variable.
In the example below changes to the Controller $scope.count
variable will automatically be reflected in the Service count
variable.
In production we're actually using the this binding to update an id on a service which then asynchronously fetches data and updates its service vars. Further binding that means that controllers automagically get updated when the service updates itself.
The code below can be seen working at http://jsfiddle.net/xuUHS/163/
View:
<div ng-controller="ServiceCtrl">
<p> This is my countService variable : {{count}}</p>
<input type="number" ng-model="count">
<p> This is my updated after click variable : {{countS}}</p>
<button ng-click="clickC()" >Controller ++ </button>
<button ng-click="chkC()" >Check Controller Count</button>
</br>
<button ng-click="clickS()" >Service ++ </button>
<button ng-click="chkS()" >Check Service Count</button>
</div>
Service/Controller:
var app = angular.module('myApp', []);
app.service('testService', function(){
var count = 10;
function incrementCount() {
count++;
return count;
};
function getCount() { return count; }
return {
get count() { return count },
set count(val) {
count = val;
},
getCount: getCount,
incrementCount: incrementCount
}
});
function ServiceCtrl($scope, testService)
{
Object.defineProperty($scope, 'count', {
get: function() { return testService.count; },
set: function(val) { testService.count = val; },
});
$scope.clickC = function () {
$scope.count++;
};
$scope.chkC = function () {
alert($scope.count);
};
$scope.clickS = function () {
++testService.count;
};
$scope.chkS = function () {
alert(testService.count);
};
}
I have used the following for "formatting" the database on device after I have changed the structure of the database in assets. I simply uncomment the line in MainActivity when I wanted that the database is read from the assets again. This will reset the device database values and structure to mach with the preoccupied database in assets folder.
//database initialization. Uncomment to clear the database
//deleteDatabase("questions.db");
Next, I will implement a button that will run the deleteDatabase so that the user can reset its progress in the game.
Your fns is a cellstr array. You need to index in to it with {} instead of () to get the single string out as char.
fns{i}
teststruct.(fns{i})
Indexing in to it with () returns a 1-long cellstr array, which isn't the same format as the char array that the ".(name)" dynamic field reference wants. The formatting, especially in the display output, can be confusing. To see the difference, try this.
name_as_char = 'a'
name_as_cellstr = {'a'}
"{0:b}".format(100) # bin: 1100100
"{0:x}".format(100) # hex: 64
"{0:o}".format(100) # oct: 144

Boundary Control Entity pattern have two versions:
- old structural, described at 127 (entity as an data model elements, control as an functions, boundary as an application interface)
- new object pattern
As an object pattern:
- Boundary is an interface for "other world"
- Control in an any internal logic (like a service in DDD pattern)
- Entity is an an persistence serwis for objects (like a repository in DDD pattern).
All classes have operations (see Fowler anemic domain model anti-pattern)
All of them is an Model component in MVC pattern. The rules:
- Only Boundary provide services for the "other world"
- Boundary can call only to Controll
- Control can call anybody
- Entity can't call anybody (!), only be called.

You can use array_walk_recursive
:
array_walk_recursive($array, function ($item, $key) {
echo "$key holds $item\n";
});
What you need is spatial search. You can use Solr Spatial search. It also got lat/long datatype built in, check here.

Below is an example of such a query:
INSERT INTO [93275].[93276].[93277].[93278] ( [Mobile Number], [Mobile Series], [Full Name], [Full Address], [Active Date], company ) IN 'I:\For Test\90-Mobile Series.accdb
SELECT [1].[Mobile Number], [1].[Mobile Series], [1].[Full Name], [1].[Full Address], [1].[Active Date], [1].[Company Name]
FROM 1
WHERE ((([1].[Mobile Series])="93275" Or ([1].[Mobile Series])="93276")) OR ((([1].[Mobile Series])="93277"));OR ((([1].[Mobile Series])="93278"));
here is how I've done this before.
The correct way in .NET 4.0 is:
if (String.IsNullOrWhiteSpace(strSearch))
The String.IsNullOrWhiteSpace
method used above is equivalent to:
if (strSearch == null || strSearch == String.Empty || strSearch.Trim().Length == 0)
// String.Empty is the same as ""
Reference for IsNullOrWhiteSpace method
http://msdn.microsoft.com/en-us/library/system.string.isnullorwhitespace.aspx
Indicates whether a specified string is Nothing, empty, or consists only of white-space characters.
In earlier versions, you could do something like this:
if (String.IsNullOrEmpty(strSearch) || strSearch.Trim().Length == 0)
The String.IsNullOrEmpty
method used above is equivalent to:
if (strSearch == null || strSearch == String.Empty)
Which means you still need to check for your "IsWhiteSpace" case with the .Trim().Length == 0
as per the example.
Reference for IsNullOrEmpty method
http://msdn.microsoft.com/en-us/library/system.string.isnullorempty.aspx
Indicates whether the specified string is Nothing or an Empty string.
Explanation:
You need to ensure strSearch
(or any variable for that matter) is not null
before you dereference it using the dot character (.
) - i.e. before you do strSearch.SomeMethod()
or strSearch.SomeProperty
you need to check that strSearch != null
.
In your example you want to make sure your string has a value, which means you want to ensure the string:
String.Empty
/ ""
)In the cases above, you must put the "Is it null?" case first, so it doesn't go on to check the other cases (and error) when the string is null
.
If there is an object with 8 methods and you have a test where you want to call 7 real methods and stub one method you have two options:
spy
you have to set it up by stubbing one methodThe official documentation on doCallRealMethod
recommends using a spy for partial mocks.
See also javadoc spy(Object) to find out more about partial mocks. Mockito.spy() is a recommended way of creating partial mocks. The reason is it guarantees real methods are called against correctly constructed object because you're responsible for constructing the object passed to spy() method.
PowerShell v5.0 adds Compress-Archive
and Expand-Archive
cmdlets. The linked pages have full examples, but the gist of it is:
# Create a zip file with the contents of C:\Stuff\
Compress-Archive -Path C:\Stuff -DestinationPath archive.zip
# Add more files to the zip file
# (Existing files in the zip file with the same name are replaced)
Compress-Archive -Path C:\OtherStuff\*.txt -Update -DestinationPath archive.zip
# Extract the zip file to C:\Destination\
Expand-Archive -Path archive.zip -DestinationPath C:\Destination
I'm not sure how efficient this is but you can use range() to slice in both axis
x=np.arange(16).reshape((4,4))
x[range(1,3), :][:,range(1,3)]
Console.Write(new string('=', 30) + "\n");
==============================
GNU Make also allows you to specify the default make target using a special variable called .DEFAULT_GOAL
. You can even unset this variable in the middle of the Makefile, causing the next target in the file to become the default target.
Use the following instead:
boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );
This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.
Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.
Oracle has decided to fix Windows XP installation. As of the JRE 8u25 release in 10/15/2014 the code of the installer has been changes so that installation on Windows XP is again possible.
However, this does not mean that Oracle is continuing to support Windows XP. They make no guarantee about current and future releases of JRE8 being compatible with Windows XP. It looks like it's a run at your own risk kind of thing.

.....
So check this kind of typos as well. Unfortunately, it can not understand the typo in compile/build time, it causes an unchecked exception and booms in runtime.

While it's true that id(object)
gets the object's address in the default CPython implementation, this is generally useless... you can't do anything with the address from pure Python code.
The only time you would actually be able to use the address is from a C extension library... in which case it is trivial to get the object's address since Python objects are always passed around as C pointers.
In general, a condition in the WHERE
clause of an SQL query can reference only a single row. The context of a WHERE
clause is evaluated before any order has been defined by an ORDER BY
clause, and there is no implicit order to an RDBMS table.
You can use a derived table to join each row to the group of rows with a lesser id
value, and produce the sum of each sum group. Then test where the sum meets your criterion.
CREATE TABLE MyTable ( id INT PRIMARY KEY, cash INT );
INSERT INTO MyTable (id, cash) VALUES
(1, 200), (2, 301), (3, 101), (4, 700);
SELECT s.*
FROM (
SELECT t.id, SUM(prev.cash) AS cash_sum
FROM MyTable t JOIN MyTable prev ON (t.id > prev.id)
GROUP BY t.id) AS s
WHERE s.cash_sum >= 500
ORDER BY s.id
LIMIT 1;
Output:
+----+----------+
| id | cash_sum |
+----+----------+
| 3 | 501 |

Make (or rather a Makefile) is a buildsystem - it drives the compiler and other build tools to build your code.
CMake is a generator of buildsystems. It can produce Makefiles, it can produce Ninja build files, it can produce KDEvelop or Xcode projects, it can produce Visual Studio solutions. From the same starting point, the same CMakeLists.txt file. So if you have a platform-independent project, CMake is a way to make it buildsystem-independent as well.
If you have Windows developers used to Visual Studio and Unix developers who swear by GNU Make, CMake is (one of) the way(s) to go.
I would always recommend using CMake (or another buildsystem generator, but CMake is my personal preference) if you intend your project to be multi-platform or widely usable. CMake itself also provides some nice features like dependency detection, library interface management, or integration with CTest, CDash and CPack.
Using a buildsystem generator makes your project more future-proof. Even if you're GNU-Make-only now, what if you later decide to expand to other platforms (be it Windows or something embedded), or just want to use an IDE?

multer is a middleware which handles “multipart/form-data” and magically & makes the uploaded files and form data available to us in request as request.files and request.body.
installing multer :- npm install multer --save
in .html file:-
<form method="post" enctype="multipart/form-data" action="/upload">
<input type="hidden" name="msgtype" value="2"/>
<input type="file" name="avatar" />
<input type="submit" value="Upload" />
</form>
in .js file:-
var express = require('express');
var multer = require('multer');
var app = express();
var server = require('http').createServer(app);
var port = process.env.PORT || 3000;
var upload = multer({ dest: 'uploads/' });
app.use(function (req, res, next) {
console.log(req.files); // JSON Object
next();
});
server.listen(port, function () {
console.log('Server successfully running at:-', port);
});
app.get('/', function(req, res) {
res.sendFile(__dirname + '/public/file-upload.html');
})
app.post('/upload', upload.single('avatar'), function(req, res) {
console.log(req.files); // JSON Object
});

Yes, there is a way. Two in fact. In October 2013 jshint added a way to ignore blocks of code like this:
// Code here will be linted with JSHint.
/* jshint ignore:start */
// Code here will be ignored by JSHint.
/* jshint ignore:end */
// Code here will be linted with JSHint.
You can also ignore a single line with a trailing comment like this:
ignoreThis(); // jshint ignore:line
The method len() returns the number of elements in the list.

Yes - absolutely. Looking up a class via reflection is, by magnitude, more expensive.
Quoting Java's documentation on reflection:
Because reflection involves types that are dynamically resolved, certain Java virtual machine optimizations can not be performed. Consequently, reflective operations have slower performance than their non-reflective counterparts, and should be avoided in sections of code which are called frequently in performance-sensitive applications.
Here's a simple test I hacked up in 5 minutes on my machine, running Sun JRE 6u10:
public class Main {
public static void main(String[] args) throws Exception
{
doRegular();
doReflection();
}
public static void doRegular() throws Exception
{
long start = System.currentTimeMillis();
for (int i=0; i<1000000; i++)
{
A a = new A();
a.doSomeThing();
}
System.out.println(System.currentTimeMillis() - start);
}
public static void doReflection() throws Exception
{
long start = System.currentTimeMillis();
for (int i=0; i<1000000; i++)
{
A a = (A) Class.forName("misc.A").newInstance();
a.doSomeThing();
}
System.out.println(System.currentTimeMillis() - start);
}
}
With these results:
35 // no reflection
465 // using reflection
Bear in mind the lookup and the instantiation are done together, and in some cases the lookup can be refactored away, but this is just a basic example.
Even if you just instantiate, you still get a performance hit:
30 // no reflection
47 // reflection using one lookup, only instantiating
Again, YMMV.
If you change your program slightly:
#include <iostream>
using namespace std;
int main()
{
int array[2];
INT NOTHING;
CHAR FOO[4];
STRCPY(FOO, "BAR");
array[0] = 1;
array[1] = 2;
array[3] = 3;
array[4] = 4;
cout << array[3] << endl;
cout << array[4] << endl;
COUT << FOO << ENDL;
return 0;
}
(Changes in capitals -- put those in lower case if you're going to try this.)
You will see that the variable foo has been trashed. Your code will store values into the nonexistent array[3] and array[4], and be able to properly retrieve them, but the actual storage used will be from foo.
So you can "get away" with exceeding the bounds of the array in your original example, but at the cost of causing damage elsewhere -- damage which may prove to be very hard to diagnose.
As to why there is no automatic bounds checking -- a correctly written program does not need it. Once that has been done, there is no reason to do run-time bounds checking and doing so would just slow down the program. Best to get that all figured out during design and coding.
C++ is based on C, which was designed to be as close to assembly language as possible.
Convert from human readable date to epoch:
long epoch = new java.text.SimpleDateFormat("MM/dd/yyyyHH:mm:ss").parse("01/01/1970 01:00:00").getTime() / 1000;
Convert from epoch to human readable date:
String date = new java.text.SimpleDateFormat("MM/dd/yyyyHH:mm:ss").format(new java.util.Date (epoch*1000));

In your invoke web request just use the parameter -UseBasicParsing
e.g. in your script (line 2) you should use:
$rss = Invoke-WebRequest -UseBasicParsing
According to the documentation, this parameter is necessary on systems where IE isn't installed or configured.
Uses the response object for HTML content without Document Object Model (DOM) parsing. This parameter is required when Internet Explorer is not installed on the computers, such as on a Server Core installation of a Windows Server operating system.
You create buttons dynamically because of that you need to call them with .live()
method if you use jquery 1.7
but this method is deprecated (you can see the list of all deprecated method here) in newer version. if you want to use jquery 1.10 or above you need to call your buttons in this way:
$(document).on('click', 'selector', function(){
// Your Code
});
For Example
If your html is something like this
<div id="btn-list">
<div class="btn12">MyButton</div>
</div>
You can write your jquery like this
$(document).on('click', '#btn-list .btn12', function(){
// Your Code
});
This worked for me
$brew install gnupg
Running the command below worked with. Tried changing server.xml
and the conf file but both didn't work.
/sbin/iptables -A INPUT -i eth0 -p tcp --dport 80 -j ACCEPT
/sbin/iptables -A INPUT -i eth0 -p tcp --dport 8080 -j ACCEPT
/sbin/iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080
sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename
sudo update-rc.d filename defaults
Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln
).
At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename
) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*
. Updated above code to reflect this.
Also as pointed out in the comments (by Charles Brandt), /filename
must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.
Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts
As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.
According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering
", in which case you have to pass sequence and runlevel configuration through command line arguments.
The equivalent argument set for the above example is
sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .
I hate to point out the obvious, but System.IO.FileNotFoundException means the program did not find the file you specified. So what you need to do is check what file your code is looking for in production.
To see what file your program is looking for in production (look at the FileName property of the exception), try these techniques:
Then look at the file system on the machine and see if the file exists. Most likely the case is that it doesn't exist.
As @jwalkerjr mentioned, you should be disposing of connections in code (if connection pooling is enabled, they are just returned to the connection pool). The prescribed way to do this is using the 'using
' statement:
// Execute stored proc to read data from repository
using (SqlConnection conn = new SqlConnection(this.connectionString))
{
using (SqlCommand cmd = conn.CreateCommand())
{
cmd.CommandText = "LoadFromRepository";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@ID", fileID);
conn.Open();
using (SqlDataReader rdr = cmd.ExecuteReader(CommandBehavior.CloseConnection))
{
if (rdr.Read())
{
filename = SaveToFileSystem(rdr, folderfilepath);
}
}
}
}
This is a decoder that is specifically written to avoid the need for a buffer, by writing directly to a putchar function. This is based on wikibook's implementation https://en.wikibooks.org/wiki/Algorithm_Implementation/Miscellaneous/Base64#C
This is not as easy to use as other options above. However, it can be of use in embedded systems, where you want to dump a large file without allocating another large buffer to store the resultant base64 datauri string. (It's a pity that datauri does not let you specify the filename).

According to your need this pattern should work just fine. Try this,
^(?=(.*\d){1})(.*\S)(?=.*[a-zA-Z\S])[0-9a-zA-Z\S]{8,}
Just create a string variable, assign the pattern, and create a boolean method which returns true if the pattern is correct, else false.
Sample:
String pattern = "^(?=(.*\d){1})(.*\S)(?=.*[a-zA-Z\S])[0-9a-zA-Z\S]{8,}";
String password_string = "Type the password here"
private boolean isValidPassword(String password_string) {
return password_string.matches(Constants.passwordPattern);
}
Aight fam, after some research and experimenting, I think the best approach is to have the thing's height at 0px
, and let it transition to an exact height. You get the exact height with JavaScript. The JavaScript isn't doing the animating, it's just changing the height value. Check it:
function setInfoHeight() {
$(window).on('load resize', function() {
$('.info').each(function () {
var current = $(this);
var closed = $(this).height() == 0;
current.show().height('auto').attr('h', current.height() );
current.height(closed ? '0' : current.height());
});
});
Whenever the page loads or is resized, the element with class info
will get its h
attribute updated. Then you could have a button trigger the style="height: __"
to set it to that previously set h
value.
function moreInformation() {
$('.icon-container').click(function() {
var info = $(this).closest('.dish-header').next('.info'); // Just the one info
var icon = $(this).children('.info-btn'); // Select the logo
// Stop any ongoing animation loops. Without this, you could click button 10
// times real fast, and watch an animation of the info showing and closing
// for a few seconds after
icon.stop();
info.stop();
// Flip icon and hide/show info
icon.toggleClass('flip');
// Metnod 1, animation handled by JS
// info.slideToggle('slow');
// Method 2, animation handled by CSS, use with setInfoheight function
info.toggleClass('active').height(icon.is('.flip') ? info.attr('h') : '0');
});
};
Here's the styling for the info
class.
.info {
display: inline-block;
height: 0px;
line-height: 1.5em;
overflow: hidden;
padding: 0 1em;
transition: height 0.6s, padding 0.6s;
&.active {
border-bottom: $thin-line;
padding: 1em;
}
}
I used this on one of my projects so class names are specific. You can change them up however you like.
The styling might not be supported cross-browser. Works fine in chrome.
Below is the live example for this code. Just click on the ?
icon to start the animation
Paste here in ~/.tmux.conf
set -g mouse on
and run on terminal
tmux source-file ~/.tmux.conf
Let me start out by saying that I don't recommend using the method I'm about to suggest. It's much better to use event driven development and bind events only to the elements you're interested in knowing whether or not the mouse is over with mouseover
, mouseout
, mouseenter
, mouseleave
, etc.
If you absolutely must have the ability to know which element the mouse is over, you'd need to write a function that binds the mouseover
event to everything in the DOM, and then store whatever the current element is in some variable.
You could so something like this:
window.which_element_is_the_mouse_on = (function() {
var currentElement;
$("body *").on('mouseover', function(e) {
if(e.target === e.currentTarget) {
currentElement = this;
}
});
return function() {
console.log(currentElement);
}
}());
Basically, I've created an immediate function which sets the event on all elements and stores the current element within the closure to minimize your footprint.
Here's a working demo that calls window.which_element_is_the_mouse_on
every second and logs what element the mouse is currently over to the console.
As you pointed out in your question it is a documented behavior. I still find it strange though. I use to repopulate the test database and even though I do not rely on the values of identity fields it was a bit of annoying to have different values when populating the database for the first time from scratch and after removing all data and populating again.
A possible solution is to use truncate to clean the table instead of delete. But then you need to drop all the constraints and recreate them afterwards
In that way it always behaves as a newly created table and there is no need to call DBCC CHECKIDENT. The first identity value will be the one specified in the table definition and it will be the same no matter if you insert the data for the first time or for the N-th
I added my resource file to my project directly, and so I was able to access the strings inside just fine with the resx file name.
Example: in Resource1.resx, key "resourceKey" -> string "dataString". To get the string "dataString", I just put Resource1.resourceKey.
There may be reasons not to do this that I don't know about, but it worked for me.
You have to measure it with a tool, or estimate it by hand, and it depends on the JVM you are using.
There is some fixed overhead per object. It's JVM-specific, but I usually estimate 40 bytes. Then you have to look at the members of the class. Object references are 4 (8) bytes in a 32-bit (64-bit) JVM. Primitive types are:
Arrays follow the same rules; that is, it's an object reference so that takes 4 (or 8) bytes in your object, and then its length multiplied by the size of its element.
Trying to do it programmatically with calls to Runtime.freeMemory()
just doesn't give you much accuracy, because of asynchronous calls to the garbage collector, etc. Profiling the heap with -Xrunhprof or other tools will give you the most accurate results.
More clarified version of above answers:
IEnumerable<IGrouping<int, ClassA>> groups = list.GroupBy(x => x.PropertyIntOfClassA);
foreach (var groupingByClassA in groups)
{
int propertyIntOfClassA = groupingByClassA.Key;
//iterating through values
foreach (var classA in groupingByClassA)
{
int key = classA.PropertyIntOfClassA;
}
}
Maybe slight overkill but created library ngx-if-empty-or-has-items it checks if an object, set, map or array is not empty. Maybe it will help somebody. It has the same functionality as ngIf (then, else and 'as' syntax is supported).
arrayOrObjWithData = ['1'] || {id: 1}
<h1 *ngxIfNotEmpty="arrayOrObjWithData">
You will see it
</h1>
or
// store the result of async pipe in variable
<h1 *ngxIfNotEmpty="arrayOrObjWithData$ | async as obj">
{{obj.id}}
</h1>
or
noData = [] || {}
<h1 *ngxIfHasItems="noData">
You will NOT see it
</h1>

The std::string.append
function isn't a good option because it doesn't accept many forms of data. A more useful alternative is to use std::stringstream
; like so:
#include <sstream>
// ...
std::stringstream ss;
//put arbitrary formatted data into the stream
ss << 4.5 << ", " << 4 << " whatever";
//convert the stream buffer into a string
std::string str = ss.str();
Try this,simple and easy
System.getProperty("os.name");
System.getProperty("os.version");
System.getProperty("os.arch");
To keep the code fluent (if code optimisation is not crucial) and you would need to do some further operations on the list:
authorsList = authorsList.Where(x => x.FirstName != "Bob").<do_some_further_Linq>;
or
authorsList = authorsList.Where(x => !setToRemove.Contains(x)).<do_some_further_Linq>;
GET will send the data as a querystring, but POST will not. Rather it will send it in the body of the request.

FROM A.tableA JOIN B.tableB

ON A.tableA.id = B.tableB.a_id;

Span is considered an in-line element. As such is basically constrains itself to the content within it. It more or less is transparent.
Think of it having the behavior of the 'b' tag.
It can be performed like <span style='font-weight: bold;'>bold text</span>
div is a block element.
My coworkers helped me with this:
select CONVERT(VARCHAR(10), <tms_column>, 112), count(*)
from table where <tms_column> > '2012-09-10'
group by CONVERT(VARCHAR(10), <tms_column>, 112);
or
select CONVERT(DATE, <tms_column>, 112), count(*)
from table where <tms_column> > '2012-09-10'
group by CONVERT(DATE, <tms_column>, 112);

If it's a framework-dependent application (the default), you run it by dotnet yourapp.dll
.
If it's a self-contained application, you run it using yourapp.exe
on Windows and ./yourapp
on Unix.
For more information about the differences between the two app types, see the .NET Core Application Deployment article on .Net Docs.
Have you looked at the -p
option of adduser
(which AFAIK is just another name for useradd
)? You may also want to look at the -P
option of luseradd
which takes a plaintext password, but I don't know if luseradd
is a standard command (it may be part of SE Linux or perhaps just an oddity of Fedora).
I have a simple example to show how to do angular 2 rc6 dynamic component.
Say, you have a dynamic html template = template1 and want to dynamic load, firstly wrap into component
@Component({template: template1})
class DynamicComponent {}
here template1 as html, may be contains ng2 component
From rc6, have to have @NgModule wrap this component. @NgModule, just like module in anglarJS 1, it decouple different part of ng2 application, so:
@Component({
template: template1,
})
class DynamicComponent {
}
@NgModule({
imports: [BrowserModule,RouterModule],
declarations: [DynamicComponent]
})
class DynamicModule { }
(Here import RouterModule as in my example there is some route components in my html as you can see later on)
Now you can compile DynamicModule as:
this.compiler.compileModuleAndAllComponentsAsync(DynamicModule).then(
factory => factory.componentFactories.find(x => x.componentType === DynamicComponent))
And we need put above in app.moudule.ts to load it, please see my app.moudle.ts. For more and full details check: https://github.com/Longfld/DynamicalRouter/blob/master/app/MyRouterLink.ts and app.moudle.ts
and see demo: http://plnkr.co/edit/1fdAYP5PAbiHdJfTKgWo?p=preview
You can also set the tableview's bounces property to NO. This will keep the section headers non-floating/static, but then you also lose the bounce property of the tableview.
You could use a Scanner
http://download.oracle.com/javase/1.5.0/docs/api/java/util/Scanner.html
The scanner can also use delimiters other than whitespace. This example reads several items in from a string:
String input = "1 fish 2 fish red fish blue fish"; Scanner s = new Scanner(input).useDelimiter("\\s*fish\\s*"); System.out.println(s.nextInt()); System.out.println(s.nextInt()); System.out.println(s.next()); System.out.println(s.next()); s.close();
prints the following output:
1 2 red blue
There's a really simple way to do this.
The problem is that .delay only effects animations, so what you need to do is make .hide() act like an animation by giving it a duration.
$("#whatever").delay().hide(1);
By giving it a nice short duration, it appears to be instant just like the regular .hide function.
Make sure that your package is installed in your $GOPATH
directory or already inside your workspace/package.
For example: if your $GOPATH = "c:\go"
, make sure that the package inside C:\Go\src\pkgName
The best way I have found is having an input type: file
then setting it to display: none
. Give it an id
. Create a button or any other element you want to open the file input.
Then add an event listener on it (button) which when clicked simulates a click on the original file input. Like clicking a button named hello but it opens a file window.
Example code
//i am using semantic ui
<button class="ui circular icon button purple send-button" id="send-btn">
<i class="paper plane icon"></i>
</button>
<input type="file" id="file" class="input-file" />
javascript
var attachButton=document.querySelector('.attach-button');
attachButton.addEventListener('click', e=>{
$('#file').trigger("click")
})

If you're not in an ipython notebook (like the OP), you can also just declare the size when you declare the figure:

plt.figure(figsize=(width, height))
I'd prefer not to use an HTML5 only element such as <section>
. Also grouping the input fields might painful if you try to generate the form with code. It's always better to produce similar markup for each one and only change the class names. Therefore I would recommend a solution that looks like this :
CSS
label, input {
display: block;
}
ul.form {
width : 500px;
padding: 0px;
margin : 0px;
list-style-type: none;
}
ul.form li {
width : 500px;
}
ul.form li input {
width : 200px;
}
ul.form li textarea {
width : 450px;
height: 150px;
}
ul.form li.twoColumnPart {
float : left;
width : 250px;
}
HTML
<form name="message" method="post">
<ul class="form">
<li class="twoColumnPart">
<label for="name">Name</label>
<input id="name" type="text" value="" name="name">
</li>
<li class="twoColumnPart">
<label for="email">Email</label>
<input id="email" type="text" value="" name="email">
</li>
<li>
<label for="subject">Subject</label>
<input id="subject" type="text" value="" name="subject">
</li>
<li>
<label for="message">Message</label>
<textarea id="message" type="text" name="message"></textarea>
</li>
</ul>
</form>
It's called String#start_with?
, not String#startswith
: In Ruby, the names of boolean-ish methods end with ?
and the words in method names are separated with an _
. Not sure where the s
went, personally, I'd prefer String#starts_with?
over the actual String#start_with?
To be thorough I normally create a pair of functions, one that takes Enum 1 and returns Enum 2 and another that takes Enum 2 and returns Enum 1. Each consists of a case statement mapping inputs to outputs and the default case throws an exception with a message complaining about an unexpected value.
In this particular case you could take advantage of the fact that the integer values of Male and Female are the same, but I'd avoid that as it's hackish and subject to breakage if either enum changes in the future.
I don't know about javax.media.j3d, so I might be mistaken, but you usually want to investigate whether there is a memory leak. Well, as others note, if it was 64MB and you are doing something with 3d, maybe it's obviously too small...
But if I were you, I'll set up a profiler or visualvm, and let your application run for extended time (days, weeks...). Then look at the heap allocation history, and make sure it's not a memory leak.
If you use a profiler, like JProfiler or the one that comes with NetBeans IDE etc., you can see what object is being accumulating, and then track down what's going on.. Well, almost always something is incorrectly not removed from a collection...
I like this to have enum in the dayNames. To reduce typing, we can do the following:
#define EP(x) [x] = #x /* ENUM PRINT */
const char* dayNames[] = { EP(Sunday), EP(Monday)};
There is a rule in Python programming called "it is Easier to Ask for Forgiveness than for Permission" (in short: EAFP). It means that you should catch exceptions instead of checking values for validity.
Thus, try the following:
try:
qByUser = byUsrUrlObj.read()
qUserData = json.loads(qByUser).decode('utf-8')
questionSubjs = qUserData["all"]["questions"]
except ValueError: # includes simplejson.decoder.JSONDecodeError
print 'Decoding JSON has failed'
EDIT: Since simplejson.decoder.JSONDecodeError
actually inherits from ValueError
(proof here), I simplified the catch statement by just using ValueError
.
findstr
sometimes hangs unexpectedly when searching large files.
I haven't confirmed the exact conditions or boundary sizes. I suspect any file larger 2GB may be at risk.
I have had mixed experiences with this, so it is more than just file size. This looks like it may be a variation on FINDSTR hangs on XP and Windows 7 if redirected input does not end with LF, but as demonstrated this particular problem manifests when input is not redirected.
The following command line session (Windows 7) demonstrates how findstr
can hang when searching a 3GB file.

Note, I've verified in a hex editor that all lines are terminated with CRLF
. The only anomaly is that the file is terminated with 0x1A
due to the way copy
works. Note however, that this anomaly doesn't cause a problem on "small" files.
With additional testing I have confirmed the following:
copy
with the /b
option for binary files prevents the addition of the 0x1A
character, and findstr
doesn't hang on the 3GB file.findstr
to hang.0x1A
character doesn't cause any problems on a "small" file. (Similarly for other terminating characters.)CRLF
after 0x1A
resolves the problem. (LF
by itself would probably suffice.)type
to pipe the file into findstr
works without hanging. (This might be due to a side effect of either type
or |
that inserts an additional End Of Line.)<
also causes findstr
to hang. But this is expected; as explained in dbenham's post: "redirected input must end in LF
".Assuming that your table name is city
and your existing Primary Key is pk_city
, you should be able to do the following:
ALTER TABLE city

Make sure that there are no records where time

, otherwise you won't be able to re-create the constraint.
I ran into this problem with a particular webpage I was maintaining. No matter what settings I changed, it kept going back to IE8 compatibility mode.
It turned out X-UA-Compatible
was set in the metadata in the head:
<meta http-equiv="X-UA-Compatible" content="IE=8" >
As I later discovered, and at least in Internet Explorer 11, you can see where it gets its "document mode" from, by going into developer tools (F12), then selecting the tab "Emulation", and checking the text below the drop down "Document mode".
Since we only support IE11 and higher, and Microsoft says document modes are deprecated, I just threw the whole thing out. That solved it.
You need to use anaconda to manage python environment dependencies. MySQL connector can be installed using conda installer
conda install -c anaconda mysql-connector-python
You can try this from the console:
adb logcat --buffer=crash
More info on this option:
adb logcat --help
...
-b <buffer>, --buffer=<buffer> Request alternate ring buffer, 'main',
'system', 'radio', 'events', 'crash', 'default' or 'all'.
Multiple -b parameters or comma separated list of buffers are
allowed. Buffers interleaved. Default -b main,system,crash.
I think I found another solution to this question.

PHP:
session_start();
$_SESSION['ipaddress'] = $_SERVER['REMOTE_ADDR'];
if(isset($_SESSION['userID'])){
if(!strpos($_SESSION['activeID'], '-')){
$_SESSION['activeID'] = $_SESSION['userID'].'-'.$_SESSION['activeID'];
}
}elseif(!isset($_SESSION['activeID'])){
$_SESSION['activeID'] = time();
}
JS
window.setInterval(function(){
var userid = '<?php echo $_SESSION['activeID']; ?>';
var ipaddress = '<?php echo $_SESSION['ipaddress']; ?>';
var action = 'data';
$.ajax({
url:'activeUser.php',
method:'POST',
data:{action:action,userid:userid,ipaddress:ipaddress},
success:function(response){
//alert(response);
}
});
}, 5000);
Ajax call to activeUser.php
if(isset($_POST['action'])){
if(isset($_POST['userid'])){
$stamp = time();
$activeid = $_POST['userid'];
$ip = $_POST['ipaddress'];
$query = "SELECT stamp FROM activeusers WHERE activeid = '".$activeid."' LIMIT 1";
$results = RUNSIMPLEDB($query);
if($results->num_rows > 0){
$query = "UPDATE activeusers SET stamp = '$stamp' WHERE activeid = '".$activeid."' AND ip = '$ip' LIMIT 1";
RUNSIMPLEDB($query);
}else{
$query = "INSERT INTO activeusers (activeid,stamp,ip)
VALUES ('".$activeid."','$stamp','$ip')";
RUNSIMPLEDB($query);
}
}
}
Database:
CREATE TABLE `activeusers` (
`id` int(11) NOT NULL,
`activeid` varchar(20) NOT NULL,
`stamp` int(11) NOT NULL,
`ip` text
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
Basically every 5 seconds the js will post to a php file that will track the user and the users ip address. Active users are simply a database record that have an update to the database time stamp within 5 seconds. Old users stop updating to the database. The ip address is used just to ensure that a user is unique so 2 people on the site at the same time don't register as 1 user.
Probably not the most efficient solution but it does the job.
I made a librairy to make Hexadecimal / Decimal conversion without the use of stdio.h
. Very simple to use :
char* dechex (int dec);
This will use calloc()
to to return a pointer to an hexadecimal string, this way the quantity of memory used is optimized, so don't forget to use free()
Here the link on github : https://github.com/kevmuret/libhex/
Anyone else stumbling upon this answer should note that jQuery now (>=1.3) has outerHeight
/outerWidth
functions to retrieve the width including padding/borders, e.g.
$(elem).outerWidth(); // Returns the width + padding + borders
To include the margin as well, simply pass true
:
$(elem).outerWidth( true ); // Returns the width + padding + borders + margins
SELECT * FROM ALL_OBJECTS WHERE OBJECT_TYPE IN ('FUNCTION','PROCEDURE','PACKAGE')
The column STATUS tells you whether the object is VALID or INVALID. If it is invalid, you have to try a recompile, ORACLE can't tell you if it will work before.
In addition to Biff MaGriff's answer. To export the file using JQuery, redirect the user to a new page.
$('#btn_export').click(function () {
window.location.href = 'NewsLetter/Export';
});
<span class="btn-pTool">
<a class="btn-pToolName" href="#"></a>
</span>
Try to add display:block
to .btn-pTool
, and give it a width and height.
Also in your code both tbn-pTool and btn-pToolName have no text content, so that may result in them not being displayed at all.
You can try to force come content in them this way
.btn-pTool, .btn-pToolName {
content: " ";
}
You cannot have spaces around the =
sign.
When you write:
STR = "foo"
bash tries to run a command named STR
with 2 arguments (the strings =
and foo
)
When you write:
STR =foo
bash tries to run a command named STR
with 1 argument (the string =foo
)
When you write:
STR= foo
bash tries to run the command foo
with STR set to the empty string in its environment.
I'm not sure if this helps to clarify or if it is mere obfuscation, but note that:
STR "=" "foo"
,STR "=foo"
,STR="" foo
.The relevant section of the sh language spec, section 2.9.1 states:
A "simple command" is a sequence of optional variable assignments and redirections, in any sequence, optionally followed by words and redirections, terminated by a control operator.
In that context, a word
is the command that bash is going to run. Any string containing =
(in any position other than at the beginning of the string) which is not a redirection and in which the portion of the string before the =
is a valid variable name is a variable assignment, while any string that is not a redirection or a variable assignment is a command. In STR = "foo"
, STR
is not a variable assignment.
he easiest way to install Pandas, like almost every other package for Python, is with pip.
Many packages (including Pandas) require a compiler, and a bunch of third-party DLLs, and many Windows users don't know how to deal with that. That's exactly why the "wheel" format was created: so packages can upload pre-built binaries.
Not every project has pre-built binary wheels for Windows yet. But you can look at Christoph Gohlke's site and find wheels for all of the most popular ones. Just follow the instructions on that page to download the wheel file and install it with pip.
But in the case of Pandas, you don't have to do that. They have wheels on their download page, and uploaded to PyPI. And the documentation tells you to use these. (Well, it first suggests you use Anaconda/Miniconda, but if you want a stock Python, use pip and the packages on PyPI.) it worked for me ...on windows 7 64 bit ,python 3.4

Further reading for any of the topics here: The Definitive Guide to Linux System Calls
I verified these using GNU Assembler (gas) on Linux.
x86-32 aka i386 Linux System Call convention:
In x86-32 parameters for Linux system call are passed using registers. %eax
for syscall_number. %ebx, %ecx, %edx, %esi, %edi, %ebp are used for passing 6 parameters to system calls.
The return value is in %eax
. All other registers (including EFLAGS) are preserved across the int $0x80
.
I took following snippet from the Linux Assembly Tutorial but I'm doubtful about this. If any one can show an example, it would be great.
If there are more than six arguments,
%ebx
must contain the memory location where the list of arguments is stored - but don't worry about this because it's unlikely that you'll use a syscall with more than six arguments.
For an example and a little more reading, refer to http://www.int80h.org/bsdasm/#alternate-calling-convention. Another example of a Hello World for i386 Linux using int 0x80
: Hello, world in assembly language with Linux system calls?
There is a faster way to make 32-bit system calls: using sysenter
. The kernel maps a page of memory into every process (the vDSO), with the user-space side of the sysenter
dance, which has to cooperate with the kernel for it to be able to find the return address. Arg to register mapping is the same as for int $0x80
. You should normally call into the vDSO instead of using sysenter
directly. (See The Definitive Guide to Linux System Calls for info on linking and calling into the vDSO, and for more info on sysenter
, and everything else to do with system calls.)
x86-32 [Free|Open|Net|DragonFly]BSD UNIX System Call convention:
Parameters are passed on the stack. Push the parameters (last parameter pushed first) on to the stack. Then push an additional 32-bit of dummy data (Its not actually dummy data. refer to following link for more info) and then give a system call instruction int $0x80
http://www.int80h.org/bsdasm/#default-calling-convention
(Note: x86-64 Mac OS X is similar but different from Linux. TODO: check what *BSD does)
Refer to section: "A.2 AMD64 Linux Kernel Conventions" of System V Application Binary Interface AMD64 Architecture Processor Supplement. The latest versions of the i386 and x86-64 System V psABIs can be found linked from this page in the ABI maintainer's repo. (See also the x86 tag wiki for up-to-date ABI links and lots of other good stuff about x86 asm.)
Here is the snippet from this section:
- User-level applications use as integer registers for passing the sequence %rdi, %rsi, %rdx, %rcx, %r8 and %r9. The kernel interface uses %rdi, %rsi, %rdx, %r10, %r8 and %r9.
- A system-call is done via the
syscall
instruction. This clobbers %rcx and %r11 as well as the %rax return value, but other registers are preserved.- The number of the syscall has to be passed in register %rax.
- System-calls are limited to six arguments, no argument is passed directly on the stack.
- Returning from the syscall, register %rax contains the result of the system-call. A value in the range between -4095 and -1 indicates an error, it is
-errno
.- Only values of class INTEGER or class MEMORY are passed to the kernel.
Remember this is from the Linux-specific appendix to the ABI, and even for Linux it's informative not normative. (But it is in fact accurate.)
This 32-bit int $0x80
ABI is usable in 64-bit code (but highly not recommended). What happens if you use the 32-bit int 0x80 Linux ABI in 64-bit code? It still truncates its inputs to 32-bit, so it's unsuitable for pointers, and it zeros r8-r11.
x86-32 Function Calling convention:
In x86-32 parameters were passed on stack. Last parameter was pushed first on to the stack until all parameters are done and then call
instruction was executed. This is used for calling C library (libc) functions on Linux from assembly.
Modern versions of the i386 System V ABI (used on Linux) require 16-byte alignment of %esp
before a call
, like the x86-64 System V ABI has always required. Callees are allowed to assume that and use SSE 16-byte loads/stores that fault on unaligned. But historically, Linux only required 4-byte stack alignment, so it took extra work to reserve naturally-aligned space even for an 8-byte double
or something.
Some other modern 32-bit systems still don't require more than 4 byte stack alignment.
x86-64 System V passes args in registers, which is more efficient than i386 System V's stack args convention. It avoids the latency and extra instructions of storing args to memory (cache) and then loading them back again in the callee. This works well because there are more registers available, and is better for modern high-performance CPUs where latency and out-of-order execution matter. (The i386 ABI is very old).
In this new mechanism: First the parameters are divided into classes. The class of each parameter determines the manner in which it is passed to the called function.
For complete information refer to : "3.2 Function Calling Sequence" of System V Application Binary Interface AMD64 Architecture Processor Supplement which reads, in part:
Once arguments are classified, the registers get assigned (in left-to-right order) for passing as follows:
- If the class is MEMORY, pass the argument on the stack.
- If the class is INTEGER, the next available register of the sequence %rdi, %rsi, %rdx, %rcx, %r8 and %r9 is used
So %rdi, %rsi, %rdx, %rcx, %r8 and %r9
are the registers in order used to pass integer/pointer (i.e. INTEGER class) parameters to any libc function from assembly. %rdi is used for the first INTEGER parameter. %rsi for 2nd, %rdx for 3rd and so on. Then call
instruction should be given. The stack (%rsp
) must be 16B-aligned when call
executes.
If there are more than 6 INTEGER parameters, the 7th INTEGER parameter and later are passed on the stack. (Caller pops, same as x86-32.)
The first 8 floating point args are passed in %xmm0-7, later on the stack. There are no call-preserved vector registers. (A function with a mix of FP and integer arguments can have more than 8 total register arguments.)
Variadic functions (like printf
) always need %al
= the number of FP register args.
There are rules for when to pack structs into registers (rdx:rax
on return) vs. in memory. See the ABI for details, and check compiler output to make sure your code agrees with compilers about how something should be passed/returned.
Note that the Windows x64 function calling convention has multiple significant differences from x86-64 System V, like shadow space that must be reserved by the caller (instead of a red-zone), and call-preserved xmm6-xmm15. And very different rules for which arg goes in which register.
public static String removechar(String fromString, Character character) {
int indexOf = fromString.indexOf(character);
if(indexOf==-1)
return fromString;
String front = fromString.substring(0, indexOf);
String back = fromString.substring(indexOf+1, fromString.length());
return front+back;
}
Here's yet another take on it (only using the test builtin command and its return code):
function is_int() { test "$@" -eq "$@" 2> /dev/null; }
input="-123"
if is_int "$input"
then
echo "Input: ${input}"
echo "Integer: ${input}"
else
echo "Not an integer: ${input}"

You can use data-*
attribute to embed custom data. The data-*
attributes gives us the ability to embed custom data attributes on all HTML elements.
jQuery .data()
method allows you to get/set data of any type to DOM elements in a way that is safe from circular references and therefore from memory leaks.
jQuery .attr()
method get/set attribute value for only the first element in the matched set.
Example:
<span id="test" title="foo" data-kind="primary">foo</span>
$("#test").attr("title");
$("#test").attr("data-kind");
$("#test").data("kind");
$("#test").data("value", "bar");
I used code that was published on CodeProject.com. If you want to use POP3, it is one of the better solutions that I have found.
One more option, not exactly what you asked, but can be useful:
Go to Settings
-> Editor
-> File and code templates
-> Includes
tab (on the right). There is a template header for the new files, you can use the username here:
/**
* @author myname
*/
For system username use:
/**
* @author ${USER}
*/

Just use this:
$master = $_GET["master"];
system('unzip' $master.'.zip');
in your code $master
is passed as a string, system will be looking for a file called $master.zip
$master = $_GET["master"];

In reply to JP's answers / comments, I have run the following test to compare the performance of the 2 methods. The Profiler
object is a custom class - but in summary, it uses a kernel32 function which is fairly accurate (Private Declare Sub GetLocalTime Lib "kernel32" (lpSystemTime As SYSTEMTIME)
).
Sub test()
Dim origNum As String
Dim creditOrDebit As String
Dim b As Boolean
Dim p As Profiler
Dim i As Long
Set p = New_Profiler
origNum = "30062600006"
creditOrDebit = "D"
p.startTimer ("nested_ifs")
For i = 1 To 1000000
If creditOrDebit = "D" Then
If origNum = "006260006" Then
b = True
ElseIf origNum = "30062600006" Then
b = True
End If
End If
Next i
p.stopTimer ("nested_ifs")
p.startTimer ("or_and")
For i = 1 To 1000000
If (origNum = "006260006" Or origNum = "30062600006") And creditOrDebit = "D" Then
b = True
End If
Next i
p.stopTimer ("or_and")
p.printReport
End Sub

Assuming the simplest option (installing rsync on the remote host) isn't feasible, you can use sshfs to mount the remote locally, and rsync from the mount directory. That way you can use all the options rsync offers, for example --exclude
.
Something like this should do:
sshfs user@server: sshfsdir
rsync --recursive --exclude=whatever sshfsdir/path/on/server /where/to/store
Note that the effectiveness of rsync (only transferring changes, not everything) doesn't apply here. This is because for that to work, rsync must read every file's contents to see what has changed. However, as rsync runs only on one host, the whole file must be transferred there (by sshfs). Excluded files should not be transferred, however.
Simple Solution, just type the below:

Enter this site: https://rpmfind.net/linux/rpm2html/search.php?query=ca-certificates , get your ca-certificate, for yout SO, for example: ftp://rpmfind.net/linux/fedora/linux/updates/24/x86_64/c/ca-certificates-2016.2.8-1.0.fc24.noarch.rpm << CentOS. Copy url of download and paste in url: wget your_url_donwload_ca-ceritificated.rpm now, install yout rpm:
rpm2cpio your_url_donwload_ca-ceritificated.rpm | cpio -idmv
now restart your service: my example this command:
sudo service2 httpd restart
very great good look
The latest google api docs document how to write to a spreadsheet with python but it's a little difficult to navigate to. Here is a link to an example of how to append.
The following code is my first successful attempt at appending to a google spreadsheet.

File sutest
#!/bin/bash
echo "uid is ${UID}"
echo "user is ${USER}"
echo "username is ${USERNAME}"
run it: `./sutest' gives me
uid is 500
user is stephenp
username is stephenp
but using sudo: sudo ./sutest
gives
uid is 0
user is root
username is stephenp
So you retain the original user name in $USERNAME when running as sudo. This leads to a solution similar to what others posted:
#!/bin/bash
sudo -u ${USERNAME} normal_command_1
root_command_1
root_command_2
sudo -u ${USERNAME} normal_command_2
# etc.
Just sudo to invoke your script in the first place, it will prompt for the password once.
I originally wrote this answer on Linux, which does have some differences with OS X
OS X (I'm testing this on Mountain Lion 10.8.3) has an environment variable SUDO_USER
when you're running sudo, which can be used in place of USERNAME
above, or to be more cross-platform the script could check to see if SUDO_USER is set and use it if so, or use USERNAME if that's set.
Changing the original script for OS X, it becomes...
#!/bin/bash
sudo -u ${SUDO_USER} normal_command_1
root_command_1
root_command_2
sudo -u ${SUDO_USER} normal_command_2
# etc.
A first stab at making it cross-platform could be...
#!/bin/bash
#
# set "THE_USER" to SUDO_USER if that's set,
# else set it to USERNAME if THAT is set,
# else set it to the string "unknown"
# should probably then test to see if it's "unknown"
#
THE_USER=${SUDO_USER:-${USERNAME:-unknown}}
sudo -u ${THE_USER} normal_command_1
root_command_1
root_command_2
sudo -u ${THE_USER} normal_command_2
# etc.
It appears you might be a bit confused as to how the .Add method works. I will refer directly to your code in my explanation.
Basically in C#, the .Add method of a List of objects does not COPY new added objects into the list, it merely copies a reference to the object (it's address) into the List. So the reason every value in the list is pointing to the same value is because you've only created 1 new DyObj. So your list essentially looks like this.
DyObjectsList[0] = &DyObj; // pointing to DyObj
DyObjectsList[1] = &DyObj; // pointing to the same DyObj
DyObjectsList[2] = &DyObj; // pointing to the same DyObj
...
The easiest way to fix your code is to create a new DyObj for every .Add. Putting the new inside of the block with the .Add would accomplish this goal in this particular instance.
var DyObjectsList = new List<dynamic>;
if (condition1) {
dynamic DyObj = new ExpandoObject();
DyObj.Required = true;
DyObj.Message = "Message 1";
DyObjectsList .Add(DyObj);
}
if (condition2) {
dynamic DyObj = new ExpandoObject();
DyObj.Required = false;
DyObj.Message = "Message 2";
DyObjectsList .Add(DyObj);
}
your resulting List essentially looks like this
DyObjectsList[0] = &DyObj0; // pointing to a DyObj
DyObjectsList[1] = &DyObj1; // pointing to a different DyObj
DyObjectsList[2] = &DyObj2; // pointing to another DyObj
Now in some other languages this approach wouldn't work, because as you leave the block, the objects declared in the scope of the block could go out of scope and be destroyed. Thus you would be left with a collection of pointers, pointing to garbage.
However in C#, if a reference to the new DyObjs exists when you leave the block (and they do exist in your List because of the .Add operation) then C# does not release the memory associated with that pointer. Therefore the Objects you created in that block persist and your List contains pointers to valid objects and your code works.
I'm leaving this answer for someone who gets in this scenario as I did.
I stumbled here and there before noticing that I mistakenly dragged and dropped the Support Library JAR file into my src folder and it was lying there. Since I had no idea how it happened or when I dropped it there, I could never imagine something was wrong there.
I was getting the same error, I found the problem after sometime and removed it. Project is now working fine.
Print the full path (also called resolved path) with:
realpath README.md
In interactive mode you can use shell expansion to list all files in the directory with their full paths:
realpath *
If you're programming a bash script, I guess you'll have a variable for the individual file names.
Thanks to VIPIN KUMAR for pointing to the related readlink
command.
You are running the [
(aka test
) command with the argument "false", not running the command false
. Since "false" is a non-empty string, the test
command always succeeds. To actually run the command, drop the [
command.
if false; then
echo "True"
else
echo "False"

I think natually do it is straightforward, whether Intellij IDEA or Android Studio, I always click new Java class menu, and then typing the class name, press Enter to create. after that, I manually typing "extends Activity" in the class file, and then import the class by shortcut key. finally, I also manually override the onCreate() method and invoke the setContentView() method.
The nodejs package tecfu/tty-table can be globally installed to do precisely this:
apt-get install nodejs
npm i -g tty-table
cat data.csv | tty-table
It can also handle streams.
For more info, see the docs for terminal usage here.
For all who come here trying to run a nginx image in a docker container, that will run as a service
As there is no whole Dockerfile, here is my whole Dockerfile
solving the issue.
Nice and working. Thanks to all answers here in order to solve the final nginx issue.

If you wish to test that a variable is bound or unbound, this works well, even after you've turned on the nounset option:
set -o noun set
if printenv variableName >/dev/null; then
# variable is bound to a value
else
# variable is unbound

You can use a single group for seconds/minutes. The following expression may suit your needs:
([0-9]+)\s*(seconds|minutes)
Lexical Analyzer takes a sequence of characters identifies a lexeme that matches the regular expression and further categorizes it to token. Thus, a Lexeme is matched string and a Token name is the category of that lexeme.
For example, consider below regular expression for an identifier with input "int foo, bar;"
letter(letter|digit|_)*
Here, foo
and bar
match the regular expression thus are both lexemes but are categorized as one token ID
i.e identifier.
Also note, next phase i.e syntax analyzer need not have to know about lexeme but a token.
Note: (replace file.ico with your actual icon filename)
Icon=".\file.ico"
on the WindowWhat i have done is that import a new project into eclipse workspace, and that path of that was be
android-sdk-macosx/extras/google/google_play_services/libproject/google-play-services_lib
and add as library in your project.. that it .. simple!! you might require to add support library in your project.
One quick and dirty way which gets the job done sometimes is:
find directory/ | xargs Command
For example to find number of lines in all files in the current directory, you can do:
find . | xargs wc -l
To be pedantic, it's probably not good to hardcode either / or \ as the path separator. Maybe this would be best?
mypath = os.path.join('c:%s' % os.sep, 'sourcedir')
or
mypath = os.path.join('c:' + os.sep, 'sourcedir')
JSONP is a way of getting around the browser's same-origin policy. How? Like this:
The goal here is to make a request to otherdomain.com
and alert
the name in the response. Normally we'd make an AJAX request:
$.get('otherdomain.com', function (response) {
var name = response.name;
alert(name);
});
However, since the request is going out to a different domain, it won't work.
We can make the request using a <script>
tag though. Both <script src="otherdomain.com"></script>
and $.get('otherdomain.com')
will result in the same request being made:
GET otherdomain.com
Q: But if we use the <script>
tag, how could we access the response? We need to access it if we want to alert
it.
A: Uh, we can't. But here's what we could do - define a function that uses the response, and then tell the server to respond with JavaScript that calls our function with the response as its argument.
Q: But what if the server won't do this for us, and is only willing to return JSON to us?
A: Then we won't be able to use it. JSONP requires the server to cooperate.
Q: Having to use a <script>
tag is ugly.
A: Libraries like jQuery make it nicer. Ex:
$.ajax({
url: "http://otherdomain.com",
jsonp: "callback",
dataType: "jsonp",
success: function( response ) {
console.log( response );
}
});
It works by dynamically creating the <script>
tag DOM element.
Q: <script>
tags only make GET requests - what if we want to make a POST request?
A: Then JSONP won't work for us.
Q: That's ok, I just want to make a GET request. JSONP is awesome and I'm going to go use it - thanks!
A: Actually, it isn't that awesome. It's really just a hack. And it isn't the safest thing to use. Now that CORS is available, you should use it whenever possible.
This is what I use:
EXEC sp_rename 'MyTable', 'MyTableNewName';
You can use the re
module for regexes, but regexes are probably overkill for what you want. I might try something like
z.write(article[:article.index("</html>") + 7]
This is much cleaner, and should be much faster than a regex based solution.
Works in Python 2.7 and higher including python3:
result = bytearray.fromhex('deadbeef')
Note: There seems to be a bug with the bytearray.fromhex()
function in Python 2.6. The python.org documentation states that the function accepts a string as an argument, but when applied, the following error is thrown:
>>> bytearray.fromhex('B9 01EF')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: fromhex() argument 1 must be unicode, not str`
