i have same problem what i did i just downloaded 32-bit dll and added it to my bin folder this is solved my problem
A JRE doesn't have a tools.jar, you need a JDK. Set your JAVA_HOME and PATH variables so that they point to a JDK, not a JRE.
For Python 3 below eliminates overhead of list conversion:
first = next(iter(prices.values()))
It can be done using SQL Server Import and Export Wizard. But if you're familiar with SSIS and don't want to run the SQL Server Import and Export Wizard, create an SSIS package that uses the Excel Source and the SQL Server Destination in the data flow.
Perhaps the best way is to write a script that starts the mysql command line client and then automatically runs whatever sql you want before it hands over the control to you.
linux comes with an application called 'expect'. it interacts with the shell in such a way as to mimic your key strokes. it can be set to start mysql, wait for you to enter your password. run further commands such as SET autocommit = 0;
then go into interactive mode so you can run any command you want.
for more on the command SET autocommit = 0;
see.. http://dev.mysql.com/doc/refman/5.0/en/innodb-transaction-model.html
I use expect to log in to a command line utility in my case it starts ssh, connects to the remote server, starts the application enters my username and password then turns over control to me. saves me heaps of typing :)
http://linux.die.net/man/1/expect
DC
Expect script provided by Michael Hinds
spawn /usr/local/mysql/bin/mysql
expect "mysql>"
send "set autocommit=0;\r"
expect "mysql>" interact
expect is pretty powerful and can make life a lot easier as in this case.
if you want to make the script run without calling expect use the shebang line
insert this as the first line in your script (hint: use which expect
to find the location of your expect executable)
#! /usr/bin/expect
then change the permissions of your script with..
chmod 0744 myscript
then call the script
./myscript
DC
All your exercise conditionals are separate and the else is only tied to the last if statement. Use else if
to bind them all together in the way I believe you intend.
The last two lines are important to align in center:
.f01 {
background-color: rgb(16, 216, 252);
padding: 100px;
text-align: left;
margin: auto;
display: table;
}
First of all, you tried to replace the entire 12.00 with '', which isn't going to give your desired results.
Second you are trying to do replace directly on a decimal. Replace must be performed on a string, so you have to CAST.
There are many ways to get your desired results, but this replace would have worked (assuming your column name is "height":
REPLACE(CAST(height as varchar(31)),'.00','')
EDIT:
This script works:
DECLARE @Height decimal(6,2);
SET @Height = 12.00;
SELECT @Height, REPLACE(CAST(@Height AS varchar(31)),'.00','');
Sure, convert the file to ascii and blast all unicode characters away. It will probably work.... BUT...
Two more sugrical approaches to fixing the problem:
Regex search all unicode characters not part non-extended ascii. In notepad++ I can search up to FFFF, which hasn't failed me yet.
[\x{80}-\x{FFFF}]
80 is hex for 128, the first extended ascii character.
After hitting "find next" and highlighting what appears to be empty space, you can close your search dialog and press CTRL+C to copy to clipboard.
Then paste the character into a unicode search tool. I usually use an online one. http://unicode.scarfboy.com/
Example: I had a bullet point (•) in my code somehow. The unicode value is 2022 (hex), but when read as ascii by the compiler you get \342 \200 \242 (3 octal values). It's not as simple as converting each octal values to hex and smashing them together. So "E2 80 A2" is NOT the hex unicode point in your code.
Reviving an old question because it seems to appear at the top of search results.
I wanted to retain transition effects while still being able to style the actionlink so I came up with this solution.
<div class="parent-style-one"> @Html.ActionLink("Homepage", "Home", "Home") </div>
.parent-style-one { /* your styles here */ }
.parent-style-one a { text-decoration: none; }
.parent-style-one a:hover { text-decoration: underline; -webkit-transition-duration: 1.1s; /* Safari */ transition-duration: 1.1s; }
This way I only target the child elements of the div in this case the action link and still be able to apply transition effects.
I Got AutoFlash light with below simple Three Steps.
<uses-permission android:name="android.permission.CAMERA" /> <uses-feature android:name="android.hardware.camera" /> <uses-permission android:name="android.permission.FLASHLIGHT"/> <uses-feature android:name="android.hardware.camera.flash" android:required="false" />
In your Camera Code do this way.
//Open Camera
Camera mCamera = Camera.open();
//Get Camera Params for customisation
Camera.Parameters parameters = mCamera.getParameters();
//Check Whether device supports AutoFlash, If you YES then set AutoFlash
List<String> flashModes = parameters.getSupportedFlashModes();
if (flashModes.contains(android.hardware.Camera.Parameters.FLASH_MODE_AUTO))
{
parameters.setFlashMode(Parameters.FLASH_MODE_AUTO);
}
mCamera.setParameters(parameters);
mCamera.startPreview();
Build + Run —> Now Go to Dim light area and Snap photo, you should get auto flash light if device supports.
Here are few :
1) ConcurrentHashMap locks only portion of Map but SynchronizedMap locks whole MAp.
2) ConcurrentHashMap has better performance over SynchronizedMap and more scalable.
3) In case of multiple reader and Single writer ConcurrentHashMap is best choice.
This text is from Difference between ConcurrentHashMap and hashtable in Java
fromCharCode returns 'a' when pressing on the numpad '1' so this methoid should be avoided

Here is the step by step process to include php code in html file ( Tested )
If PHP is working there is only one step left to use PHP scripts in files with *.html or *.htm extensions as well. The magic word is ".htaccess". Please see the Wikipedia definition of .htaccess to learn more about it. According to Wikipedia it is "a directory-level configuration file that allows for decentralized management of web server configuration."
You can probably use such a .htaccess configuration file for your purpose. In our case you want the webserver to parse HTML files like PHP files.
First, create a blank text file and name it ".htaccess". You might ask yourself why the file name starts with a dot. On Unix-like systems this means it is a dot-file is a hidden file. (Note: If your operating system does not allow file names starting with a dot just name the file "xyz.htaccess" temporarily. As soon as you have uploaded it to your webserver in a later step you can rename the file online to ".htaccess") Next, open the file with a simple text editor like the "Editor" in MS Windows. Paste the following line into the file: AddType application/x-httpd-php .html .htm If this does not work, please remove the line above from your file and paste this alternative line into it, for PHP5: AddType application/x-httpd-php5 .html .htm Now upload the .htaccess file to the root directory of your webserver. Make sure that the name of the file is ".htaccess". Your webserver should now parse *.htm and *.html files like PHP files.
You can try if it works by creating a HTML-File like the following. Name it "php-in-html-test.htm", paste the following code into it and upload it to the root directory of your webserver:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE>Use PHP in HTML files</TITLE>
</HEAD>
<BODY>
<h1>
<?php echo "It works!"; ?>
</h1>
</BODY>
</HTML>
Try to open the file in your browser by typing in: http://www.your-domain.com/php-in-html-test.htm (once again, please replace your-domain.com by your own domain...) If your browser shows the phrase "It works!" everything works fine and you can use PHP in .*html and *.htm files from now on. However, if not, please try to use the alternative line in the .htaccess file as we showed above. If is still does not work please contact your hosting provider.
I just posted this to my brand spanking new blog: http://jasonturim.wordpress.com/2013/09/01/angularjs-drag-and-drop/
Code here: https://github.com/logicbomb/lvlDragDrop
Demo here: http://logicbomb.github.io/ng-directives/drag-drop.html
Here are the directives these rely on a UUID service which I've included below:
var module = angular.module("lvl.directives.dragdrop", ['lvl.services']);
module.directive('lvlDraggable', ['$rootScope', 'uuid', function($rootScope, uuid) {
return {
restrict: 'A',
link: function(scope, el, attrs, controller) {
console.log("linking draggable element");
angular.element(el).attr("draggable", "true");
var id = attrs.id;
if (!attrs.id) {
id = uuid.new()
angular.element(el).attr("id", id);
}
el.bind("dragstart", function(e) {
e.dataTransfer.setData('text', id);
$rootScope.$emit("LVL-DRAG-START");
});
el.bind("dragend", function(e) {
$rootScope.$emit("LVL-DRAG-END");
});
}
}
}]);
module.directive('lvlDropTarget', ['$rootScope', 'uuid', function($rootScope, uuid) {
return {
restrict: 'A',
scope: {
onDrop: '&'
},
link: function(scope, el, attrs, controller) {
var id = attrs.id;
if (!attrs.id) {
id = uuid.new()
angular.element(el).attr("id", id);
}
el.bind("dragover", function(e) {
if (e.preventDefault) {
e.preventDefault(); // Necessary. Allows us to drop.
}
e.dataTransfer.dropEffect = 'move'; // See the section on the DataTransfer object.
return false;
});
el.bind("dragenter", function(e) {
// this / e.target is the current hover target.
angular.element(e.target).addClass('lvl-over');
});
el.bind("dragleave", function(e) {
angular.element(e.target).removeClass('lvl-over'); // this / e.target is previous target element.
});
el.bind("drop", function(e) {
if (e.preventDefault) {
e.preventDefault(); // Necessary. Allows us to drop.
}
if (e.stopPropagation) {
e.stopPropagation(); // Necessary. Allows us to drop.
}
var data = e.dataTransfer.getData("text");
var dest = document.getElementById(id);
var src = document.getElementById(data);
scope.onDrop({dragEl: src, dropEl: dest});
});
$rootScope.$on("LVL-DRAG-START", function() {
var el = document.getElementById(id);
angular.element(el).addClass("lvl-target");
});
$rootScope.$on("LVL-DRAG-END", function() {
var el = document.getElementById(id);
angular.element(el).removeClass("lvl-target");
angular.element(el).removeClass("lvl-over");
});
}
}
}]);
UUID service
angular
.module('lvl.services',[])
.factory('uuid', function() {
var svc = {
new: function() {
function _p8(s) {
var p = (Math.random().toString(16)+"000000000").substr(2,8);
return s ? "-" + p.substr(0,4) + "-" + p.substr(4,4) : p ;
}
return _p8() + _p8(true) + _p8(true) + _p8();
},
empty: function() {
return '00000000-0000-0000-0000-000000000000';
}
};
return svc;
});
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)")
With Javascript you can get full size profile images like this
pass your accessToken
to the getface()
function from your FB.init
call
function getface(accessToken){
FB.api('/me/friends', function (response) {
for (id in response.data) {
var homie=response.data[id].id
FB.api(homie+'/albums?access_token='+accessToken, function (aresponse) {
for (album in aresponse.data) {
if (aresponse.data[album].name == "Profile Pictures") {
FB.api(aresponse.data[album].id + "/photos", function(aresponse) {
console.log(aresponse.data[0].images[0].source);
});
}
}
});
}
});
}
We all know this works.
INSERT INTO `TableName`(`col-1`,`col-2`)
SELECT `col-1`,`col-2`
===========================
Below method can be used in case of multiple "select" statements. Just for information.
INSERT INTO `TableName`(`col-1`,`col-2`)
select 1,2 union all
select 1,2 union all
select 1,2 ;
Browsers, by default, have their option to print background-colors and images turned off. You can add some lines in CSS to bypass this. Just add:
* {
-webkit-print-color-adjust: exact !important; /* Chrome, Safari */
color-adjust: exact !important; /*Firefox*/
}
According to the documentation:
When should I use an attribute versus an element? Use an element when you are creating a component that is in control of the template. The common case for this is when you are creating a Domain-Specific Language for parts of your template. Use an attribute when you are decorating an existing element with new functionality.
Edit following comment on pitfalls for a complete answer:
Assuming you're building an app that should run on Internet Explorer <= 8, whom support has been dropped by AngularJS team from AngularJS 1.3, you have to follow the following instructions in order to make it working: https://docs.angularjs.org/guide/ie
In Sass we can write:
background-color: rgba(#ff0000, 0.5);
as it was suggested in Hex representation of a color with alpha channel?
update the 'name' attribute:
UPDATE test SET data=data||'{"name":"my-other-name"}' WHERE id = 1;
and if you wanted to remove for example the 'name' and 'tags' attributes:
UPDATE test SET data=data-'{"name","tags"}'::text[] WHERE id = 1;
Using JDK 1.6 or later
It has been pointed out by Justin in the comments below that keytool alone is capable of doing this using the following command (although only in JDK 1.6 and later):
keytool -importkeystore -srckeystore mypfxfile.pfx -srcstoretype pkcs12
-destkeystore clientcert.jks -deststoretype JKS
Using JDK 1.5 or below
OpenSSL can do it all. This answer on JGuru is the best method that I've found so far.
Firstly make sure that you have OpenSSL installed. Many operating systems already have it installed as I found with Mac OS X.
The following two commands convert the pfx file to a format that can be opened as a Java PKCS12 key store:
openssl pkcs12 -in mypfxfile.pfx -out mypemfile.pem
openssl pkcs12 -export -in mypemfile.pem -out mykeystore.p12 -name "MyCert"
NOTE that the name provided in the second command is the alias of your key in the new key store.
You can verify the contents of the key store using the Java keytool utility with the following command:
keytool -v -list -keystore mykeystore.p12 -storetype pkcs12
Finally if you need to you can convert this to a JKS key store by importing the key store created above into a new key store:
keytool -importkeystore -srckeystore mykeystore.p12 -destkeystore clientcert.jks -srcstoretype pkcs12 -deststoretype JKS
The full list is:
DB, DW, DD, DQ, DT, DDQ, and DO (used to declare initialized data in the output file.)
See: http://www.tortall.net/projects/yasm/manual/html/nasm-pseudop.html
They can be invoked in a wide range of ways: (Note: for Visual-Studio - use "h" instead of "0x" syntax - eg: not 0x55 but 55h instead):
db 0x55 ; just the byte 0x55
db 0x55,0x56,0x57 ; three bytes in succession
db 'a',0x55 ; character constants are OK
db 'hello',13,10,'$' ; so are string constants
dw 0x1234 ; 0x34 0x12
dw 'A' ; 0x41 0x00 (it's just a number)
dw 'AB' ; 0x41 0x42 (character constant)
dw 'ABC' ; 0x41 0x42 0x43 0x00 (string)
dd 0x12345678 ; 0x78 0x56 0x34 0x12
dq 0x1122334455667788 ; 0x88 0x77 0x66 0x55 0x44 0x33 0x22 0x11
ddq 0x112233445566778899aabbccddeeff00
; 0x00 0xff 0xee 0xdd 0xcc 0xbb 0xaa 0x99
; 0x88 0x77 0x66 0x55 0x44 0x33 0x22 0x11
do 0x112233445566778899aabbccddeeff00 ; same as previous
dd 1.234567e20 ; floating-point constant
dq 1.234567e20 ; double-precision float
dt 1.234567e20 ; extended-precision float
DT does not accept numeric constants as operands, and DDQ does not accept float constants as operands. Any size larger than DD does not accept strings as operands.
To use information_schema and not collide with other sessions:
select *
from tempdb.INFORMATION_SCHEMA.COLUMNS
where table_name =
object_name(
object_id('tempdb..#test'),
(select database_id from sys.databases where name = 'tempdb'))
Go to the directory where you put additional libraries and delete duplicated libraries.
Use the function Contains
from the strings package.
import (
"strings"
)
strings.Contains("something", "some") // true
It is actually very easy to do this using the "set" and "get" methods available on an express object.
Example as follows, say you have a variable called config with your configuration related stuff that you want to be available in other places:
In app.js:
var config = require('./config');
app.configure(function() {
...
app.set('config', config);
...
}
In routes/index.js
exports.index = function(req, res){
var config = req.app.get('config');
// config is now available
...
}
Using parts of @benoit answer, I will use this:
DECLARE
varTmp NUMBER:=0;
BEGIN
-- checks
SELECT nvl((SELECT 1 FROM table WHERE name = 'john'), 0) INTO varTmp FROM dual;
-- insert
IF (varTmp = 1) THEN
INSERT INTO table (john, null)
END IF;
END;
Sorry for I don't use any full given answer, but I need IF
check because my code is much more complex than this example table with name and age fields. I need a very clear code. Well thanks, I learned a lot! I'll accept @benoit answer.
class CPerson:
def __init__(self, age):
self._age = age
def run(self):
pass
@property
def age(self): return self._age
@staticmethod
def my_static_method(): print("Life is short, you need Python")
@classmethod
def say(cls, msg): return msg
test_class = CPerson
# print(dir(test_class)) # list all the fields and methods of your object
print([(name, t) for name, t in test_class.__dict__.items() if type(t).__name__ == 'function' and not name.startswith('__')])
print([(name, t) for name, t in test_class.__dict__.items() if type(t).__name__ != 'function' and not name.startswith('__')])
output
[('run', <function CPerson.run at 0x0000000002AD3268>)]
[('age', <property object at 0x0000000002368688>), ('my_static_method', <staticmethod object at 0x0000000002ACBD68>), ('say', <classmethod object at 0x0000000002ACF0B8>)]
I was receiving this error and also notices that the application Postman was also falling but was working in app Advanced Rest Client (ARC) and working in Android. So i had to install Charles to debug the communication and I notices that response code was -1. The problem was that REST programmer forgot to return response code 200.
I hope that this help other developers.
Just in case anyone dropping by google is seeking a small utility library, ShortId (https://www.npmjs.com/package/shortid) meets all the requirements of this question. It allows specifying allowed characters and length, and guarantees non-sequential, non-repeating strings.
To make this more of a real answer, the core of that library uses the following logic to produce its short ids:
function encode(lookup, number) {
var loopCounter = 0;
var done;
var str = '';
while (!done) {
str = str + lookup( ( (number >> (4 * loopCounter)) & 0x0f ) | randomByte() );
done = number < (Math.pow(16, loopCounter + 1 ) );
loopCounter++;
}
return str;
}
/** Generates the short id */
function generate() {
var str = '';
var seconds = Math.floor((Date.now() - REDUCE_TIME) * 0.001);
if (seconds === previousSeconds) {
counter++;
} else {
counter = 0;
previousSeconds = seconds;
}
str = str + encode(alphabet.lookup, version);
str = str + encode(alphabet.lookup, clusterWorkerId);
if (counter > 0) {
str = str + encode(alphabet.lookup, counter);
}
str = str + encode(alphabet.lookup, seconds);
return str;
}
I have not edited this to reflect only the most basic parts of this approach, so the above code includes some additional logic from the library. If you are curious about everything it is doing, take a look at the source: https://github.com/dylang/shortid/tree/master/lib
I would do add it to Postbuild events to copy necessary libraries to the output directories. Something like XCopy pathtolibraries targetdirectory
You can find them on project properties -> Build Events.
If you have a very big amount of strings (or any other type) case all doing the same thing, I recommend the use of a string list combined with the string.Contains property.
So if you have a big switch statement like so:
switch (stringValue)
{
case "cat":
case "dog":
case "string3":
...
case "+1000 more string": // Too many string to write a case for all!
// Do something;
case "a lonely case"
// Do something else;
.
.
.
}
You might want to replace it with an if
statement like this:
// Define all the similar "case" string in a List
List<string> listString = new List<string>(){ "cat", "dog", "string3", "+1000 more string"};
// Use string.Contains to find what you are looking for
if (listString.Contains(stringValue))
{
// Do something;
}
else
{
// Then go back to a switch statement inside the else for the remaining cases if you really need to
}
This scale well for any number of string cases.
Modules are fine for storing enums and some global variables, constants and shared functions. its very good thing and I often use it. Declared variables are visible acros entire project.
Just found that issue corresponding to my problem. Using HandlerMapping constants I was able to wrote a small utility for that purpose:
/**
* Extract path from a controller mapping. /controllerUrl/** => return matched **
* @param request incoming request.
* @return extracted path
*/
public static String extractPathFromPattern(final HttpServletRequest request){
String path = (String) request.getAttribute(
HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
String bestMatchPattern = (String ) request.getAttribute(HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE);
AntPathMatcher apm = new AntPathMatcher();
String finalPath = apm.extractPathWithinPattern(bestMatchPattern, path);
return finalPath;
}
I haven't tried it yet, but it looks like NuGet Package Explorer should be able to do it:
https://github.com/NuGetPackageExplorer/NuGetPackageExplorer
(or like Colonel Panic says, 7-zip should probably do it)
You could try my Linked Tree Map implementation.
Nginx can act as a reverse proxy server which works just like a project manager. When it gets a request it analyses it and forwards the request to upstream(project members) or handles itself. Nginx has two ways of handling a request based on how its configured.
forward the request to another server
server{
server_name mydomain.com sub.mydomain.com;
location /{
proxy_pass http://127.0.0.1:8000;
proxy_set_header Host $host;
proxy_pass_request_headers on;
}
location /static/{
alias /my/static/files/path;
}
}
Server the request
With this configuration, when the request url is
mydomain.com/static/myjs.js
it returns themyjs.js
file in/my/static/files/path
folder. When you configure nginx to serve static files, it handles the request itself.
forward the request to another server
When the request url is
mydomain.com/dothis
nginx will forwards the request to http://127.0.0.1:8000. The service which is running on the localhost 8000 port will receive the request and returns the response to nginx and nginx returns the response to the client.
When you run node.js server on the port 8000 nginx will forward the request to node.js. Write node.js logic and handle the request. That's it you have your nodejs server running behind the nginx server.
If you wish to run any other services other than nodejs just run another service like Django, flask, php on different ports and config it in nginx.

OLD ANSWER (not so complete :))
In order to create good software, you have to know what that software is all about. You cannot create a banking software system unless you have a good understanding of what banking is all about, one must understand the domain of banking.
From: Domain Driven Design by Eric Evans.
This book does a pretty good job of describing DDD.
Register to download a summary of the book, or download the summary directly.
You must use the global
declaration when you wish to alter the value assigned to a global variable.
You do not need it to read from a global variable. Note that calling a method on an object (even if it alters the data within that object) does not alter the value of the variable holding that object (absent reflective magic).
I've written a log file monitor before, and I found that the impact on system performance of polling the attributes of a single file, a few times a second, is actually very small.
Java 7, as part of NIO.2 has added the WatchService API
The WatchService API is designed for applications that need to be notified about file change events.
This example reads 6 bytes into a byte array and writes it to another byte array. It does an XOR operation with the bytes so that the result written to the file is the same as the original starting values. The file is always 6 bytes in size, since it writes at position 0.

As GvS said, but I also find it useful to use strongly typed views so that I can write something like
@Html.Partial(MVC.Student.Index(), model)
without magic strings.
If you mean to change the directory in which the program execution will occur, go to "Run configurations" in the Run tab.
Then select your project and go to the "Arguments" tab, you can change the directory there. By default it is the root directory of your project.
Here it is:
function call_func(input) {
var evaled = eval('(' + input + ')');
var newDiv = document.createElement('div');
var id = evaled.id;
var name = evaled.Student_name;
var dob = evaled.student_dob;
var html = '<b>ID:</b>';
html += '<a href="/learningyii/index.php?r=student/view& id=' + id + '">' + id + '</a>';
html += '<br/>';
html += '<b>Student Name:</b>';
html += name;
html += '<br/>';
html += '<b>Student DOB:</b>';
html += dob;
html += '<br/>';
newDiv.innerHTML = html;
newDiv.setAttribute('class', 'view');
$('#StudentGridViewId').find('.items').prepend(newDiv);
};
In SQL, a comparison between a null
value and any other value (including another null
) using a comparison operator (eg =
, !=
, <
, etc) will result in a null
, which is considered as false
for the purposes of a where clause (strictly speaking, it's "not true", rather than "false", but the effect is the same).
The reasoning is that a null
means "unknown", so the result of any comparison to a null
is also "unknown". So you'll get no hit on rows by coding where my_column = null
.
SQL provides the special syntax for testing if a column is null
, via is null
and is not null
, which is a special condition to test for a null
(or not a null
).
Here's some SQL showing a variety of conditions and and their effect as per above.
create table t (x int, y int);
insert into t values (null, null), (null, 1), (1, 1);
select 'x = null' as test , x, y from t where x = null
union all
select 'x != null', x, y from t where x != null
union all
select 'not (x = null)', x, y from t where not (x = null)
union all
select 'x = y', x, y from t where x = y
union all
select 'not (x = y)', x, y from t where not (x = y);
returns only 1 row (as expected):
TEST X Y
x = y 1 1
See this running on SQLFiddle
Turned out there was some extra code in the AppModel that was messing things up:
in beforeFind
and afterFind
:
App::Import("Session");
$session = new CakeSession();
$sim_id = $session->read("Simulation.id");
I don't know why, but that was what the problem was. Removing those lines fixed the issue I was having.
With Java 8 in picture, jcmd
is the preferred approach.
jcmd <PID> Thread.print
Following is the snippet from Oracle documentation :
The release of JDK 8 introduced Java Mission Control, Java Flight Recorder, and jcmd utility for diagnosing problems with JVM and Java applications. It is suggested to use the latest utility, jcmd instead of the previous jstack utility for enhanced diagnostics and reduced performance overhead.
However, shipping this with the application may be licensing implications which I am not sure.
USE TIMESTAMPDIFF
MySQL function. For example, you can use:
SELECT TIMESTAMPDIFF(SECOND, '2012-06-06 13:13:55', '2012-06-06 15:20:18')
In your case, the third parameter of TIMSTAMPDIFF
function would be the current login time (NOW()
). Second parameter would be the last login time, which is already in the database.
void foo<TOne, TTwo>()
where TOne : BaseOne
where TTwo : BaseTwo

Just had the same issue, for those having the same one it may be that you put the library on the modulepath rather than the classpath while adding it to your project
It depends with the office you have installed, if you have x64 bit office then you must compile the application as a x64 to allow it to run, so if you want it to run on x36 then you must install office x86 to accept, i tried all the solutions above but none worked until when i realised i had office x64bit and so i built the application as x64 and worked
Or you can use this one http://plugins.jquery.com/project/parseQuery, it's smaller than most (minified 449 bytes), returns an object representing name-value pairs.
Whereas in Laravel 4.2 I would use:
{{ $users->links('view.name') }}
In Laravel 5 you can replicate the above with the following:
@include('view.name', ['object' => $users])
Now in the included view, $object
will have the pagination methods available, such as currentPage()
, lastPage()
, perPage()
, etc.
You can view all methods available at http://laravel.com/docs/5.0/pagination

Running a command through /usr/bin/env
has the benefit of looking for whatever the default version of the program is in your current environment.
This way, you don't have to look for it in a specific place on the system, as those paths may be in different locations on different systems. As long as it's in your path, it will find it.
One downside is that you will be unable to pass more than one argument (e.g. you will be unable to write /usr/bin/env awk -f
) if you wish to support Linux, as POSIX is vague on how the line is to be interpreted, and Linux interprets everything after the first space to denote a single argument. You can use /usr/bin/env -S
on some versions of env
to get around this, but then the script will become even less portable and break on fairly recent systems (e.g. even Ubuntu 16.04 if not later).
Another downside is that since you aren't calling an explicit executable, it's got the potential for mistakes, and on multiuser systems security problems (if someone managed to get their executable called bash
in your path, for example).
#!/usr/bin/env bash #lends you some flexibility on different systems
#!/usr/bin/bash #gives you explicit control on a given system of what executable is called
In some situations, the first may be preferred (like running python scripts with multiple versions of python, without having to rework the executable line). But in situations where security is the focus, the latter would be preferred, as it limits code injection possibilities.
you can use ImageView as Button. Create an ImageView and set clickable true after in write imageView.setOnClickListener for ImageView.
<ImageView
android:clickable="true"
android:focusable="true"`
android:id="@+id/imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
and in Activity's oncreate:
imageView.setOnClickListener(...
i initially came here with the same problem. I had jus installed Oracle 12c on Windows 8 (64-bit),but i have since resolved it by 'TNSPING xe' on the command line... If the connection isn't established or name not found,try the database name,in my case it was 'orcl'... 'TNSPING orcl' again and if it pings successfully then u need to change the SID to 'orcl' in this case (or whatever database name u used)...
onRestoreInstanceState()
is called only when recreating activity after it was killed by the OS. Such situation happen when:
In contrast: if you are in your activity and you hit Back
button on the device, your activity is finish()ed (i.e. think of it as exiting desktop application) and next time you start your app it is started "fresh", i.e. without saved state because you intentionally exited it when you hit Back
.
Other source of confusion is that when an app loses focus to another app onSaveInstanceState()
is called but when you navigate back to your app onRestoreInstanceState()
may not be called. This is the case described in the original question, i.e. if your activity was NOT killed during the period when other activity was in front onRestoreInstanceState()
will NOT be called because your activity is pretty much "alive".
All in all, as stated in the documentation for onRestoreInstanceState()
:
Most implementations will simply use onCreate(Bundle) to restore their state, but it is sometimes convenient to do it here after all of the initialization has been done or to allow subclasses to decide whether to use your default implementation. The default implementation of this method performs a restore of any view state that had previously been frozen by onSaveInstanceState(Bundle).
As I read it: There is no reason to override onRestoreInstanceState()
unless you are subclassing Activity
and it is expected that someone will subclass your subclass.
The second thing i did was Uninstall my Anti-Virus software (AVG Antivirus) {sounds crazy but, i had to}. it reduced gradle build time upto 40%
The first thing i did was enable offline mode (1. click on Gradle usually on the right side of the editor 2. click on the connection button to toggle) it reduced the gradle build time for upto 20%
so my Gradle build time was reduced for upto 60% by doing these two things
finalName is created as:
<build>
<finalName>${project.artifactId}-${project.version}</finalName>
</build>
One of the solutions is to add own property:
<properties>
<finalName>${project.artifactId}-${project.version}</finalName>
</properties>
<build>
<finalName>${finalName}</finalName>
</build>
And now try:
mvn -DfinalName=build clean package
I had the same issue until I added Response.Buffer = False. Try changing the code to the following.
Response.Buffer = False Response.ContentType = "application/vnd.ms-excel" Response.AddHeader "Content-Disposition", "attachment; filename=excelTest.xls"
The only problem I have now is that when Excel opens the file I get the following message.
The file you are trying to open, 'FileName[1].xls', is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?
When you open the file the data all appears in separate columns, but the spreadsheet is all white, no borders between the cells.
Hope that helps.
SHA1
is a cryptographic hash function, so the intention of the design was to avoid what you are trying to do.
However, breaking a SHA1
hash is technically possible. You can do so by just trying to guess what was hashed. This brute-force approach is of course not efficient, but that's pretty much the only way.
So to answer your question: yes, it is possible, but you need significant computing power. Some researchers estimate that it costs $70k - $120k.
As far as we can tell today, there is also no other way but to guess the hashed input. This is because operations such as mod
eliminate information from your input. Suppose you calculate mod 5
and you get 0
. What was the input? Was it 0
, 5
or 500
? You see, you can't really 'go back' in this case.
Update PHP 7.4
Curly brace access syntax is deprecated since PHP 7.4
Update 2019
Moving on to the best practices of OOPS, @MrTrick's answer must be marked as correct, although my answer provides a hacked solution its not the best method.
Simply iterate its using {}
Example:
$videos{0}->id
This way your object is not destroyed and you can easily iterate through object.
For PHP 5.6 and below use this
$videos{0}['id']
Both array() and the stdClass objects can be accessed using the
current()
key()
next()
prev()
reset()
end()
functions.
So, if your object looks like
object(stdClass)#19 (3) {
[0]=>
object(stdClass)#20 (22) {
["id"]=>
string(1) "123"
etc...
Then you can just do;
$id = reset($obj)->id; //Gets the 'id' attr of the first entry in the object
If you need the key for some reason, you can do;
reset($obj); //Ensure that we're at the first element
$key = key($obj);
Hope that works for you. :-) No errors, even in super-strict mode, on PHP 5.4
2022 Update:
After PHP 7.4, using current()
, end()
, etc functions on objects is deprecated.
In newer versions of PHP, use the ArrayIterator class:
$objIterator = new ArrayIterator($obj);
$id = $objIterator->current()->id; // Gets the 'id' attr of the first entry in the object
$key = $objIterator->key(); // and gets the key
my.ini LOCATION ON WINDOWS MYSQL 5.6 MSI (USING THE INSTALL WIZARD)
Open a Windows command shell and type: echo %PROGRAMDATA%
. On Windows Vista this results in: C:\ProgramData
.
According to http://dev.mysql.com/doc/refman/5.6/en/option-files.html, the first location MySQL will look under is in %PROGRAMDATA%\MySQL\MySQL Server 5.6\my.ini
. In your Windows shell if you do ls "%PROGRAMDATA%\MySQL\MySQL Server 5.6\my.ini"
, you will see that the file is there.
Unlike most suggestions you will find in Stackoverflow and around the web, putting the file in C:\Program Files\MySQL\MySQL Server 5.6\my.ini
WILL NOT WORK. Neither will C:\Program Files (x86)\MySQL\MySQL Server 5.1
. The reason being quoted on the MySQL link posted above:
On Windows, MySQL programs read startup options from the following files, in the specified order (top items are used first).
The 5.6 MSI installer does create a my.ini in the highest priority location, meaning no other file will ever be found/used, except for the one created by the installer.
The solution accepted above will not work for 5.6 MSI-based installs.
here it's a simple:
File file = new File(path);
int size = (int) file.length();
byte[] bytes = new byte[size];
try {
BufferedInputStream buf = new BufferedInputStream(new FileInputStream(file));
buf.read(bytes, 0, bytes.length);
buf.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Add permission in manifest.xml:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
This is covered in the PHP documentation for booleans and type comparison tables.
When converting to boolean, the following values are considered FALSE:
FALSE
itself0
(zero)0.0
(zero)'0'
NULL
(including unset variables)Every other value is considered TRUE.
For the most part you treat it as if you are validating any other kind of control but use the InitialValue property of the required field validator.
<asp:RequiredFieldValidator ID="rfv1" runat="server" ControlToValidate="your-dropdownlist" InitialValue="Please select" ErrorMessage="Please select something" />
Basically what it's saying is that validation will succeed if any other value than the 1 set in InitialValue is selected in the dropdownlist.
If databinding you will need to insert the "Please select" value afterwards as follows
this.ddl1.Items.Insert(0, "Please select");
Why can't you use absolute positioning? Vertical-align does not work (except for tables). Make your container's position: relative. Then absolutely position the internal divs using bottom: 0; Should work like a charm.
EDIT By zoidberg (i will update the answer instead)
<div style="position:relative; border: 1px solid red;width: 40px; height: 40px;">
<div style="border:1px solid green;position: absolute; bottom: 0; left: 0; width: 20px; height: 20px;"></div>
<div style="border:1px solid blue;position: absolute; bottom: 0; left: 20px; width: 20px height: 20px;"></div>
</div>
I had this message in Android Studio 2.1.1 in the Gradle Build tab. I installed a lot of files from the SDK Manager but it did not help.
I needed to click the next tab "Gradle Sync". There was a link "Install Repository and sync project" which installed the "Android Support Repository".

Using WGET:
Create a shell script called wgetgdrive.sh as below:
#!/bin/bash
# Get files from Google Drive
# $1 = file ID
# $2 = file name
URL="https://docs.google.com/uc?export=download&id=$1"
wget --load-cookies /tmp/cookies.txt "https://docs.google.com/uc?export=download&confirm=$(wget --quiet --save-cookies /tmp/cookies.txt --keep-session-cookies --no-check-certificate $URL -O- | sed -rn 's/.*confirm=([0-9A-Za-z_]+).*/\1\n/p')&id=$1" -O $2 && rm -rf /tmp/cookies.txt
Give the right permissions to execute the script
In terminal, run:
./wgetgdrive.sh <file ID> <filename>
for example:
./wgetgdrive.sh 1lsDPURlTNzS62xEOAIG98gsaW6x2PYd2 images.zip
Just create a php file and write the code

The first and stable debugger for MySQL is in dbForge Studio for MySQL
int max = 50;
int min = 1;
double random = Math.random() * 49 + 1;
or
int random = (int )(Math.random() * 50 + 1);
This will give you value from 1 to 50 in case of int or 1.0 (inclusive) to 50.0 (exclusive) in case of double
Why?
random() method returns a random number between 0.0 and 0.9..., you multiply it by 50, so upper limit becomes 0.0 to 49.999... when you add 1, it becomes 1.0 to 50.999..., now when you truncate to int, you get 1 to 50. (thanks to @rup in comments). leepoint's awesome write-up on both the approaches.
Random rand = new Random();
int value = rand.nextInt(50);
This will give value from 0 to 49.
For 1 to 50: rand.nextInt((max - min) + 1) + min;

Maybe it's possible to debug PHP on Visual Studio, but it's simpler and more logical to use Eclipse PDT or Netbeans IDE for your PHP projects, aside from Visual Studio if you need to use both technologies from two different vendors.

I solved to install the same version of .NET on WIN that was configured in my Unity project. (Player Settings)
In the "build.gradle" for your app, (the app, not the project), add this:

First, as already said, you cannot add multiple allow-from hosts, that's not supported.
Second, you need to dynamically extract that value from the HTTP referrer, which means that you can't add the value to Web.config, because it's not always the same value.
It will be necessary to do browser-detection to avoid adding allow-from when the browser is Chrome (it produces an error on the debug - console, which can quickly fill the console up, or make the application slow). That also means you need to modify the ASP.NET browser detection, as it wrongly identifies Edge as Chrome.
This can be done in ASP.NET by writing a HTTP-module which runs on every request, that appends a http-header for every response, depending on the request's referrer. For Chrome, it needs to add Content-Security-Policy.

You need to register the context_EndRequest function in the HTTP-module Init function.
public class RequestLanguageChanger : System.Web.IHttpModule
{
void System.Web.IHttpModule.Dispose()
{
// throw new NotImplementedException();
}
void System.Web.IHttpModule.Init(System.Web.HttpApplication context)
{
// https://stackoverflow.com/questions/441421/httpmodule-event-execution-order
context.EndRequest += new System.EventHandler(context_EndRequest);
}
// context_EndRequest Code from above comes here
}
Next you need to add the module to your application. You can either do this programmatically in Global.asax by overriding the Init function of the HttpApplication, like this:
namespace ChangeRequestLanguage
{
public class Global : System.Web.HttpApplication
{
System.Web.IHttpModule mod = new libRequestLanguageChanger.RequestLanguageChanger();
public override void Init()
{
mod.Init(this);
base.Init();
}
protected void Application_Start(object sender, System.EventArgs e)
{
}
protected void Session_Start(object sender, System.EventArgs e)
{
}
protected void Application_BeginRequest(object sender, System.EventArgs e)
{
}
protected void Application_AuthenticateRequest(object sender, System.EventArgs e)
{
}
protected void Application_Error(object sender, System.EventArgs e)
{
}
protected void Session_End(object sender, System.EventArgs e)
{
}
protected void Application_End(object sender, System.EventArgs e)
{
}
}
}
or you can add entries to Web.config if you don't own the application source-code:
<httpModules>
<add name="RequestLanguageChanger" type= "libRequestLanguageChanger.RequestLanguageChanger, libRequestLanguageChanger" />
</httpModules>
</system.web>
<system.webServer>
<validation validateIntegratedModeConfiguration="false"/>
<modules runAllManagedModulesForAllRequests="true">
<add name="RequestLanguageChanger" type="libRequestLanguageChanger.RequestLanguageChanger, libRequestLanguageChanger" />
</modules>
</system.webServer>
</configuration>
The entry in system.webServer is for IIS7+, the other in system.web is for IIS 6.
Note that you need to set runAllManagedModulesForAllRequests to true, for that it works properly.
The string in type is in the format "Namespace.Class, Assembly"
.
Note that if you write your assembly in VB.NET instead of C#, VB creates a default-Namespace for each project, so your string will look like
"[DefaultNameSpace.Namespace].Class, Assembly"
If you want to avoid this problem, write the DLL in C#.
Use the HAVING
, not WHERE
clause, for aggregate result comparison.
Taking the query at face value:
SELECT *
FROM db.table
HAVING COUNT(someField) > 1
Ideally, there should be a GROUP BY
defined for proper valuation in the HAVING
clause, but MySQL does allow hidden columns from the GROUP BY...
Is this in preparation for a unique constraint on someField
? Looks like it should be...
jQuery("#input").live('change', function() {
// since we check more than once against the value, place it in a var.
var inputvalue = $("#input").attr("value");
// if it's value **IS NOT** ""
if(inputvalue !== "") {
jQuery(this).css('outline', 'solid 1px red');
}
// else if it's value **IS** ""
else if(inputvalue === "") {
alert('empty');
}
});
I had this error today and discovered it was an incorrectly-formatted year...
select * from es_timeexpense where parsedate > to_date('12/3/2018', 'MM/dd/yyy')
Notice the year has only three 'y's. It should have 4.
Double-check your format.
You know, using a custom deleter isn't the best way to go, as you will have to mention it all over your code.
Instead, as you are allowed to add specializations to namespace-level classes in ::std
as long as custom types are involved and you respect the semantics, do that:
Specialize std::default_delete
:
template <>
struct ::std::default_delete<Bar> {
default_delete() = default;
template <class U>
constexpr default_delete(default_delete<U>) noexcept {}
void operator()(Bar* p) const noexcept { destroy(p); }
};
And maybe also do std::make_unique()
:
template <>
inline ::std::unique_ptr<Bar> ::std::make_unique<Bar>() {
auto p = create();
if (!p)
throw std::runtime_error("Could not `create()` a new `Bar`.");
return { p };
}
I'm using a custom view that I layout on top of the other ones and that just draws the 4 small corners in the same color as the background. This works whatever the view contents are and does not allocate much memory.
public class RoundedCornersView extends View {
private float mRadius;
private int mColor = Color.WHITE;
private Paint mPaint;
private Path mPath;
public RoundedCornersView(Context context) {
super(context);
init();
}
public RoundedCornersView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
TypedArray a = context.getTheme().obtainStyledAttributes(
attrs,
R.styleable.RoundedCornersView,
0, 0);
try {
setRadius(a.getDimension(R.styleable.RoundedCornersView_radius, 0));
setColor(a.getColor(R.styleable.RoundedCornersView_cornersColor, Color.WHITE));
} finally {
a.recycle();
}
}
private void init() {
setColor(mColor);
setRadius(mRadius);
}
private void setColor(int color) {
mColor = color;
mPaint = new Paint();
mPaint.setColor(mColor);
mPaint.setStyle(Paint.Style.FILL);
mPaint.setAntiAlias(true);
invalidate();
}
private void setRadius(float radius) {
mRadius = radius;
RectF r = new RectF(0, 0, 2 * mRadius, 2 * mRadius);
mPath = new Path();
mPath.moveTo(0,0);
mPath.lineTo(0, mRadius);
mPath.arcTo(r, 180, 90);
mPath.lineTo(0,0);
invalidate();
}
@Override
protected void onDraw(Canvas canvas) {
/*Paint paint = new Paint();
paint.setColor(Color.RED);
canvas.drawRect(0, 0, mRadius, mRadius, paint);*/
int w = getWidth();
int h = getHeight();
canvas.drawPath(mPath, mPaint);
canvas.save();
canvas.translate(w, 0);
canvas.rotate(90);
canvas.drawPath(mPath, mPaint);
canvas.restore();
canvas.save();
canvas.translate(w, h);
canvas.rotate(180);
canvas.drawPath(mPath, mPaint);
canvas.restore();
canvas.translate(0, h);
canvas.rotate(270);
canvas.drawPath(mPath, mPaint);
}
}
NB.: Now instead of
runProguard false
you'll need to use
minifyEnabled false
If you think jQuery is kind of overkill for such a primitive task, you could do something like that:
//your object
var o = {
foo:"bar",
arr:[1,2,3],
subo: {
foo2:"bar2"
}
};
//called with every property and its value
function process(key,value) {
console.log(key + " : "+value);
}
function traverse(o,func) {
for (var i in o) {
func.apply(this,[i,o[i]]);
if (o[i] !== null && typeof(o[i])=="object") {
//going one step down in the object tree!!
traverse(o[i],func);
}
}
}
//that's all... no magic, no bloated framework
traverse(o,process);
@echo off
set /p "ipa= ENTER FOLDER NAME TO DELETE> "

If you validate , option 1 comes up as an error in html 5, so option 2 is correct.
So if you're using Vscode and Mingw then you should first make sure that the bin
folder of the mingw
is included in the environment path and it is preferred to change the mingw32-make.exe
to make
to ease the task and then create a makefile
and include this code in it .
all:
gcc -o filename filename.c
./filename
Then save the makefile and open Vscode Code
terminal and write make
. Then makefile will get executed.
You can check out my add on for firefox. It allows to cross domain in the lastest firefox version: https://addons.mozilla.org/en-US/firefox/addon/cross-domain-cors/
Assuming that you really mean "print" on a real printing terminal:
>>> text = 'foo bar\r\noof\trab\r\n'
>>> ''.join(s if i & 1 else (s + '\b' * len(s)) * 2 + s
... for i, s in enumerate(re.split(r'(\s+)', text)))
'foo\x08\x08\x08foo\x08\x08\x08foo bar\x08\x08\x08bar\x08\x08\x08bar\r\noof\x08\
x08\x08oof\x08\x08\x08oof\trab\x08\x08\x08rab\x08\x08\x08rab\r\n'
Just send that to your stdout
.
The core problem is what you define line and whether end-on-line character sequence is part of the line or not. UNIX-based editors (such as VIM) or tools (such as Git) use EOL character sequence as line terminator, therefore it's a part of the line. It's similar to use of semicolon (;) in C and Pascal. In C semicolon terminates statements, in Pascal it separates them.
The best way to fix it I have looked for the code or trick how to center nav menu and found the real solutions it works for all browsers and for my friends ;)
Here is how I have done:
body {
margin: 0;
padding: 0;
}
div maincontainer {
margin: 0 auto;
width: ___px;
text-align: center;
}
ul {
margin: 0;
padding: 0;
}
ul li {
margin-left: auto;
margin-right: auto;
}
and do not forget to set doctype html5
For Bootstrap 4.0 beta (and I assume this will stay for final) there is a change - be aware that the hidden classes were removed.
See the docs: https://getbootstrap.com/docs/4.0/utilities/display/
In order to hide the content on mobile and display on the bigger devices you have to use the following classes:
d-none d-sm-block
The first class set display none all across devices and the second one display it for devices "sm" up (you could use md, lg, etc. instead of sm if you want to show on different devices.
I suggest to read about that before migration:
https://getbootstrap.com/docs/4.0/migration/#responsive-utilities
A simple solution of error is that you first need to change the folder directory in command prompt. By default in command prompt or in terminal(Inside Android studio in the bottom)tab the path is set to C:\Users#Name of your PC that you selected\AndroidStudioProjects#app name\flutter_app> Change accordingly:- C:\Users#Name of your PC that you selected\AndroidStudioProjects#app name\flutter_app>cd\
This is basically an updated version of the accepted answer for connect version 3:
var connect = require('connect');
var serveStatic = require('serve-static');
var app = connect();
app.use(serveStatic(__dirname, {'index': ['index.html']}));
app.listen(3000);
I also added a default option so that index.html is served as a default.
Use the TRUNCATE TABLE
command.
use lodash
GLOBAL.utils = require('lodash')
var arr1 = ['first' , 'second'];
var arr2 = ['second '];
var result = utils.difference(arr1 , arr2);
console.log ( "result :" + result );
In Rails 4.1.0, I have faced problem with saving latitude and longitude to MySql database. It can't save large fraction number with float data type. And I change the data type to decimal and working for me.
def change change_column :cities, :latitude, :decimal, :precision => 15, :scale => 13 change_column :cities, :longitude, :decimal, :precision => 15, :scale => 13 end
SELECT
distributor_id,
COUNT(*) AS TOTAL,
COUNT(IF(level='exec',1,null)),
COUNT(IF(level='personal',1,null))
FROM sometable;
COUNT
only counts non null
values and the DECODE
will return non null value 1
only if your condition is satisfied.
You've obviously considered lots of ways to write the SQL such that it prints out okay, but how about changing the 'print' statement you use for debug logging, rather than writing your SQL in ways you don't like? Using your favourite option above, how about a logging function such as this:
def debugLogSQL(sql):
print ' '.join([line.strip() for line in sql.splitlines()]).strip()
sql = """
select field1, field2, field3, field4
from table"""
if debug:
debugLogSQL(sql)
This would also make it trivial to add additional logic to split the logged string across multiple lines if the line is longer than your desired length.
While it may immediately seem useful to utilize class instance variables, since class instance variable are shared among subclasses and they can be referred to within both singleton and instance methods, there is a singificant drawback. They are shared and so subclasses can change the value of the class instance variable, and the base class will also be affected by the change, which is usually undesirable behavior:
class C
@@c = 'c'
def self.c_val
@@c
end
end
C.c_val
=> "c"
class D < C
end
D.instance_eval do
def change_c_val
@@c = 'd'
end
end
=> :change_c_val
D.change_c_val
(irb):12: warning: class variable access from toplevel
=> "d"
C.c_val
=> "d"
Rails introduces a handy method called class_attribute. As the name implies, it declares a class-level attribute whose value is inheritable by subclasses. The class_attribute value can be accessed in both singleton and instance methods, as is the case with the class instance variable. However, the huge benefit with class_attribute in Rails is subclasses can change their own value and it will not impact parent class.
class C
class_attribute :c
self.c = 'c'
end
C.c
=> "c"
class D < C
end
D.c = 'd'
=> "d"
C.c
=> "c"
function add(){
var first=parseFloat($("#first").val());
var second=parseFloat($("#second").val());
$("#result").val(+(first+second).toFixed(2));
}
declare @dt1 datetime='2012/06/13 08:11:12', @dt2 datetime='2012/06/12 02:11:12'
select CAST((@dt2-@dt1) as time(0))
The most readable way is
x = 10 if a > b else 11
but you can use and
and or
, too:
x = a > b and 10 or 11
The "Zen of Python" says that "readability counts", though, so go for the first way.
Also, the and-or trick will fail if you put a variable instead of 10
and it evaluates to False
.
However, if more than the assignment depends on this condition, it will be more readable to write it as you have:
if A[i] > B[j]:
x = A[i]
i += 1
else:
x = A[j]
j += 1
unless you put i
and j
in a container. But if you show us why you need it, it may well turn out that you don't.
Not tested, but it should work (edited after comments)
lapply(mylist, write, "test.txt", append=TRUE, ncolumns=1000)
Unicode escapes only work in unicode strings, so this
a="\u2026"
is actually a string of 6 characters: '\', 'u', '2', '0', '2', '6'.
To make unicode out of this, use decode('unicode-escape')
:
a="\u2026"
print repr(a)
print repr(a.decode('unicode-escape'))
## '\\u2026'
## u'\u2026'
It's a Xcode bug (Xcode 8.2.1) and I've reported that to Apple, it will happen when you have a large dictionary literal or a nested dictionary literal. You have to break your dictionary to smaller parts and add them with append method until Apple fixes the bug.

You can use an npm module called depcheck (requires at least version 10 of Node).
Install the module:
npm install depcheck -g
or
yarn global add depcheck
Run it and find the unused dependencies:
depcheck
The good thing about this approach is that you don't have to remember the find
or grep
command.
To run without installing use npx
:
npx depcheck

Whenever I have had odd issues like this, I usually sit down with a tool like WireShark and look at the raw data being passed back and forth. You might be surprised where things are being disconnected, and you are only being notified when you try and read.
A Record lets you create a new type from a Union. The values in the Union are used as attributes of the new type.
For example, say I have a Union like this:
type CatNames = "miffy" | "boris" | "mordred";
Now I want to create an object that contains information about all the cats, I can create a new type using the values in the CatName Union as keys.
type CatList = Record<CatNames, {age: number}>
If I want to satisfy this CatList, I must create an object like this:
const cats:CatList = {
miffy: { age:99 },
boris: { age:16 },
mordred: { age:600 }
}
You get very strong type safety:
I used this recently to create a Status component. The component would receive a status prop, and then render an icon. I've simplified the code quite a lot here for illustrative purposes
I had a union like this:
type Statuses = "failed" | "complete";
I used this to create an object like this:
const icons: Record<
Statuses,
{ iconType: IconTypes; iconColor: IconColors }
> = {
failed: {
iconType: "warning",
iconColor: "red"
},
complete: {
iconType: "check",
iconColor: "green"
};
I could then render by destructuring an element from the object into props, like so:
const Status = ({status}) => <Icon {...icons[status]} />
If the Statuses union is later extended or changed, I know my Status component will fail to compile and I'll get an error that I can fix immediately. This allows me to add additional error states to the app.
Note that the actual app had dozens of error states that were referenced in multiple places, so this type safety was extremely useful.
Use the Java ternary operator to quickly check if your character is there before removing it. This strips the leading character only if it exists, if passed a blank string, return blankstring.
String header = "";
header = header.startsWith("#") ? header.substring(1) : header;
System.out.println(header);
header = "foobar";
header = header.startsWith("#") ? header.substring(1) : header;
System.out.println(header);
header = "#moobar";
header = header.startsWith("#") ? header.substring(1) : header;
System.out.println(header);
Prints:
blankstring
foobar
moobar
String a = "Cool";
a = a.replace("o","");
//variable 'a' contains the string "Cl"
String b = "Cool";
b = b.replaceFirst("o","");
//variable 'b' contains the string "Col"
First of all, don't try the following command as suggested by Germain above.
`sudo apt-get remove 'python3.*'`
In Ubuntu, many software depends upon Python3 so if you will execute this command it will remove all of them as it happened with me. I found following answer useful to recover it.
If you want to use different python versions for different projects then create virtual environments it will be very useful. refer to the following link to create virtual environments.
Creating Virtual Environment also helps in using Tensorflow and Keras in Jupyter Notebook.

You're trying to use a dict
as a key to another dict
or in a set
. That does not work because the keys have to be hashable. As a general rule, only immutable objects (strings, integers, floats, frozensets, tuples of immutables) are hashable (though exceptions are possible). So this does not work:
>>> dict_key = {"a": "b"}
>>> some_dict[dict_key] = True
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'dict'
To use a dict as a key you need to turn it into something that may be hashed first. If the dict you wish to use as key consists of only immutable values, you can create a hashable representation of it like this:
>>> key = frozenset(dict_key.items())
Now you may use key
as a key in a dict
or set
:
>>> some_dict[key] = True
>>> some_dict
{frozenset([('a', 'b')]): True}
Of course you need to repeat the exercise whenever you want to look up something using a dict:
>>> some_dict[dict_key] # Doesn't work
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'dict'
>>> some_dict[frozenset(dict_key.items())] # Works
True
If the dict
you wish to use as key has values that are themselves dicts and/or lists, you need to recursively "freeze" the prospective key. Here's a starting point:
def freeze(d):
if isinstance(d, dict):
return frozenset((key, freeze(value)) for key, value in d.items())
elif isinstance(d, list):
return tuple(freeze(value) for value in d)
return d

I think you are confused with the printf(String format, Object... args)
method. The first argument is the format string, which is mandatory, rest you can pass an arbitrary number of Object
s.
There is no such overload for both the print()
and println()
methods.

By this you can get any index in *ngFor
loop in ANGULAR ...
<ul>
<li *ngFor="let object of myArray; let i = index; let first = first ;let last = last;">
<div *ngIf="first">
// write your code...
</div>
<div *ngIf="last">
// write your code...
</div>
</li>
</ul>
We can use these alias in *ngFor
index
: number
: let i = index
to get all index of object.first
: boolean
: let first = first
to get first index of object.last
: boolean
: let last = last
to get last index of object.odd
: boolean
: let odd = odd
to get odd index of object.even
: boolean
: let even = even
to get even index of object.thead {
position: fixed;
height: 10px; /* This is whatever height you want */
}
tbody {
position: fixed;
margin-top: 10px; /* This has to match the height of thead */
height: 300px; /* This is whatever height you want */
}
It's as easy as the following:
info_1 = "one piece of info"
info_2 = "another piece"
vars = (info_1, info_2)
# 'vars' is now a tuple with the values ("info_1", "info_2")
However, tuples in Python are immutable, so you cannot append variables to a tuple once it is created.
There's quite a few good sp_who3 user stored procedures out there - I'm sure Adam Machanic did a really good one, AFAIK.

I deleted *.csproj.user ( resharper file) of my project, then, close all tabs and reopen it. After that I was able to compile my project and there was no resharper warnings.
Jae's above solution worked for me. The manifest solution didn't work for me. Thanks Jae.
Setup:On my windows 8.1 64 bit non tablet laptop I downloaded eclipse 64 bit with jdk 64 bit.
It mostly depends on the (other) activity in the database. Operations like this effectively freeze the entire database for other sessions. Another consideration is the datamodel and the presence of constraints,triggers, etc.
My first approach is always: create a (temp) table with a structure similar to the target table (create table tmp AS select * from target where 1=0), and start by reading the file into the temp table. Then I check what can be checked: duplicates, keys that already exist in the target, etc.
Then I just do a "do insert into target select * from tmp" or similar.
If this fails, or takes too long, I abort it and consider other methods (temporarily dropping indexes/constraints, etc)
This should get you started:
R> qplot(hwy, cty, data = mpg) +
facet_grid(. ~ manufacturer) +
theme(strip.text.x = element_text(size = 8, colour = "orange", angle = 90))
See also this question: How can I manipulate the strip text of facet plots in ggplot2?
I think you're looking for this:
elements = [10, 11, 12, 13, 14, 15]
indices = (1,1,2,1,5)
result_list = [elements[i] for i in indices]

You can use INFORMATION_SCHEMA.TABLES
to retrieve information about your database tables.
As mentioned in the Microsoft Tables Documentation:
INFORMATION_SCHEMA.TABLES
returns one row for each table in the current database for which the current user has permissions.
The following query, therefore, will return the number of tables in the specified database:
USE MyDatabase
SELECT COUNT(*)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
As of SQL Server 2008, you can also use sys.tables
to count the the number of tables.
From the Microsoft sys.tables Documentation:
sys.tables
returns a row for each user table in SQL Server.
The following query will also return the number of table in your database:
SELECT COUNT(*)
FROM sys.tables
I am not convinced that you'll need an external sorting program in Bash.
Here is my implementation for the simple bubble-sort algorithm.
function bubble_sort()
{ #
# Sorts all positional arguments and echoes them back.
#
# Bubble sorting lets the heaviest (longest) element sink to the bottom.
#
local array=($@) max=$(($# - 1))
while ((max > 0))
do
local i=0
while ((i < max))
do
if [ ${array[$i]} \> ${array[$((i + 1))]} ]
then
local t=${array[$i]}
array[$i]=${array[$((i + 1))]}
array[$((i + 1))]=$t
fi
((i += 1))
done
((max -= 1))
done
echo ${array[@]}
}
array=(a c b f 3 5)
echo " input: ${array[@]}"
echo "output: $(bubble_sort ${array[@]})"
This shall print:
input: a c b f 3 5
output: 3 5 a b c f
This code works. I have a date input field that has been set to read only which forces the user to select from the calendar.
for a start date:
var updateInput = "var input = document.getElementById('startDateInput');" +
"input.value = '18-Jan-2016';" +
"angular.element(input).scope().$apply(function(s) { s.$parent..searchForm[input.name].$setViewValue(input.value);})";
browser.executeScript(updateInput);
for an end date:
var updateInput = "var input = document.getElementById('endDateInput');" +
"input.value = '22-Jan-2016';" +
"angular.element(input).scope().$apply(function(s) { s.$parent.searchForm[input.name].$setViewValue(input.value);})";
browser.executeScript(updateInput);
If you simply do NOT want any status bar at all, you need to update your plist with this data: To do this, in the plist, add those 2 settings:
<key>UIStatusBarHidden</key>
<true/>
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>
In iOS 7 you are expected to design your app with an overlaid transparent status bar in mind. See the new iOS 7 Weather app for example.
git commit -a -m "Your commit message here"
will quickly commit all changes with the commit message. Git commit "title" and "description" (as you call them) are nothing more than just the first line, and the rest of the lines in the commit message, usually separated by a blank line, by convention. So using this command will just commit the "title" and no description.
If you want to commit a longer message, you can do that, but it depends on which shell you use.
In bash the quick way would be:
git commit -a -m $'Commit title\n\nRest of commit message...'
When I ran into this problem, it was a result of trying to use an inner class to serve as the DO. Construction of the inner class (silently) required an instance of the enclosing class -- which wasn't available to Jackson.
In this case, moving the inner class to its own .java file fixed the problem.
You can create different python development environments graphically from Anaconda Navigator. I had same problem while working with different python versions so I used anaconda navigator to create different python development environments and used different python versions in each environments.
Here is the help documentation for this.
https://docs.anaconda.com/anaconda/navigator/tutorials/manage-environments/
$("div[id^=" + controlid + "]")
will return all the controls with the same name but you need to ensure that the text should not present in any of the controls
Add overflow: auto;
to the style and the two finger scroll should work.
I have used the below as a background for the layout:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="1dp"
android:dashWidth="10px"
android:dashGap="10px"
android:color="android:@color/black"
/>
</shape>
You could do this with the following list comprehension:
[mylist[i:] + [newelement] + mylist[:i] for i in xrange(len(mylist),-1,-1)]
With your example:
>>> mylist=['A','B']
>>> newelement='X'
>>> [mylist[i:] + [newelement] + mylist[:i] for i in xrange(len(mylist),-1,-1)]
[['X', 'A', 'B'], ['B', 'X', 'A'], ['A', 'B', 'X']]
In this post Scrollview vertical and horizontal in android they talk about a possible solution, quoting:
Matt Clark has built a custom view based on the Android source, and it seems to work perfectly: http://blog.gorges.us/2010/06/android-two-dimensional-scrollview
Beware that the class in that page has a bug calculating the view's horizonal width. A fix by Manuel Hilty is in the comments:
Solution: Replace the statement on line 808 by the following:
final int childWidthMeasureSpec = MeasureSpec.makeMeasureSpec(lp.leftMargin + lp.rightMargin, MeasureSpec.UNSPECIFIED);
html_safe
:
Marks a string as trusted safe. It will be inserted into HTML with no additional escaping performed.
"<a>Hello</a>".html_safe
#=> "<a>Hello</a>"
nil.html_safe
#=> NoMethodError: undefined method `html_safe' for nil:NilClass
raw
:
raw
is just a wrapper around html_safe
. Use raw
if there are chances that the string will be nil
.
raw("<a>Hello</a>")
#=> "<a>Hello</a>"
raw(nil)
#=> ""
h
alias for html_escape
:
A utility method for escaping HTML tag characters. Use this method to escape any unsafe content.
In Rails 3 and above it is used by default so you don't need to use this method explicitly
A simpler approach relies on redirection from the page LOGIN_REDIRECT_URL. The key thing to realize is that the user information is automatically included in the request.
Suppose:
LOGIN_REDIRECT_URL = '/profiles/home'
and you have configured a urlpattern:
(r'^profiles/home', home),
Then, all you need to write for the view home()
is:
from django.http import HttpResponseRedirect
from django.urls import reverse
from django.contrib.auth.decorators import login_required
@login_required
def home(request):
return HttpResponseRedirect(
reverse(NAME_OF_PROFILE_VIEW,
args=[request.user.username]))
where NAME_OF_PROFILE_VIEW
is the name of the callback that you are using. With django-profiles, NAME_OF_PROFILE_VIEW
can be 'profiles_profile_detail'.
Configure The "php.ini" File
First, ensure that PHP is configured to allow file uploads. In your "php.ini" file, search for the file_uploads directive, and set it to On:
file_uploads = On
Create The HTML Form
Next, create an HTML form that allow users to choose the image file they want to upload:
<!DOCTYPE html>
<html>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>
Some rules to follow for the HTML form above: Make sure that the form uses method="post" The form also needs the following attribute: enctype="multipart/form-data". It specifies which content-type to use when submitting the form Without the requirements above, the file upload will not work. Other things to notice: The type="file" attribute of the tag shows the input field as a file-select control, with a "Browse" button next to the input control The form above sends data to a file called "upload.php", which we will create next.
Create The Upload File PHP Script
The "upload.php" file contains the code for uploading a file:
<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
?>
Have you tried setting
li {list-style-type: none;}
According to Need an unordered list without any bullets, you need to add this style to the li elements.
If you want to fake a $_GET (or a $_POST) when including a file, you can use it like you would use any other var, like that:
$_GET['key'] = 'any get value you want';
include('your_other_file.php');
It's for controlling aspect on mobile phones and tablets. You will find more info here : https://developer.mozilla.org/en-US/docs/Mozilla/Mobile/Viewport_meta_tag
You have to override the bootstrap default by being a bit more specific. Try this for a black background:
html body {
background-color: rgba(0,0,0,1.00);
}
How about this? (requires y non-negative, so don't use this in the rare case where y is a variable with no non-negativity guarantee)
q = (x > 0)? 1 + (x - 1)/y: (x / y);
I reduced y/y
to one, eliminating the term x + y - 1
and with it any chance of overflow.
I avoid x - 1
wrapping around when x
is an unsigned type and contains zero.
For signed x
, negative and zero still combine into a single case.
Probably not a huge benefit on a modern general-purpose CPU, but this would be far faster in an embedded system than any of the other correct answers.

Add this function inside your Auth\LoginController.php
use Illuminate\Http\Request;
And also add this
public function logout(Request $request)
{
$this->guard()->logout();
$request->session()->invalidate();
return $this->loggedOut($request) ?: redirect('/login');
}
The value 3172978990 is greater than 2147483647 – the maximum value for INT
– hence the error. MySQL integer types and their ranges are listed here.
Also note that the (10)
in INT(10)
does not define the "size" of an integer. It specifies the display width of the column. This information is advisory only.
To fix the error, change your datatype to VARCHAR
. Phone and Fax numbers should be stored as strings. See this discussion.
I know this is old but this answer came up in search results. For the next guy - the proposed and accepted answer works, however the code initially submitted in the question is lower-level than it needs to be. Nobody got time for that.
//one-line post request/response...
response, err := http.PostForm(APIURL, url.Values{
"ln": {c.ln},
"ip": {c.ip},
"ua": {c.ua}})
//okay, moving on...
if err != nil {
//handle postform error
}
defer response.Body.Close()
body, err := ioutil.ReadAll(response.Body)
if err != nil {
//handle read response error
}
fmt.Printf("%s\n", string(body))
I guess your code uses somewhere in the second case a singular matrix (i.e. not invertible), and the solve function needs to invert it. This has nothing to do with the size but with the fact that some of your vectors are (probably) colinear.
Turns out it is possible to enter a host name directly into the playbook, so running the playbook with hosts: imac-2.local
will work fine. But it's kind of clunky.
A better solution might be defining the playbook's hosts using a variable, then passing in a specific host address via --extra-vars
:
# file: user.yml (playbook)
---
- hosts: '{{ target }}'
user: ...
Running the playbook:
ansible-playbook user.yml --extra-vars "target=imac-2.local"
If {{ target }}
isn't defined, the playbook does nothing. A group from the hosts file can also be passed through if need be. Overall, this seems like a much safer way to construct a potentially destructive playbook.
Playbook targeting a single host:
$ ansible-playbook user.yml --extra-vars "target=imac-2.local" --list-hosts
playbook: user.yml
play #1 (imac-2.local): host count=1
imac-2.local
Playbook with a group of hosts:
$ ansible-playbook user.yml --extra-vars "target=office" --list-hosts
playbook: user.yml
play #1 (office): host count=3
imac-1.local
imac-2.local
imac-3.local
Forgetting to define hosts is safe!
$ ansible-playbook user.yml --list-hosts
playbook: user.yml
play #1 ({{target}}): host count=0
Try Adminer. The whole application is in one PHP file, which means that the deployment is as easy as it can get. It's more powerful than phpMyAdmin; it can edit views, procedures, triggers, etc.
Adminer is also a universal tool, it can connect to MySQL, PostgreSQL, SQLite, MS SQL, Oracle, SimpleDB, Elasticsearch and MongoDB.
You should definitely give it a try.
You can install on Ubuntu with sudo apt-get install adminer
or you can also download the latest version from adminer.org
I would say that it would be better from a conceptual point of view to just leave the old object (the one from the web service) as it is, and put the values you need in a new object. I'm assuming you are extracting specific fields at one point or another anyway, if not on the client, then at least on the server. The fact that you chose to use field names that are the same as those from the web service, only lowercase, doesn't really change this. So, I'd advise to do something like this:
var myObj = {
field1: theirObj.FIELD1,
field2: theirObj.FIELD2,
(etc)
}
Of course, I'm making all kinds of assumptions here, which may not be true. If this doesn't apply to you, or if it's too slow (is it? I haven't tested, but I imagine the difference gets smaller as the number of fields increases), please ignore all of this :)
If you don't want to do this, and you only have to support specific browsers, you could also use the new getters to also return "uppercase(field)": see http://robertnyman.com/2009/05/28/getters-and-setters-with-javascript-code-samples-and-demos/ and the links on that page for more information.
EDIT:
Incredibly, this is also almost twice as fast, at least on my FF3.5 at work. See: http://jsperf.com/spiny001
mysqladmin
is not a SQL statement. It's a little helper utility program you'll find on your MySQL server... and "flush-hosts" is one of the things it can do. ("status" and "shutdown" are a couple of other things that come to mind).
You type that command from a shell prompt.
Alternately, from your query browser (such as phpMyAdmin), the SQL statement you're looking for is simply this:
FLUSH HOSTS;
Just call fig.tight_layout()
as you normally would. (pyplot
is just a convenience wrapper. In most cases, you only use it to quickly generate figure and axes objects and then call their methods directly.)
There shouldn't be a difference between the QtAgg
backend and the default backend (or if there is, it's a bug).
E.g.
import matplotlib.pyplot as plt
#-- In your case, you'd do something more like:
# from matplotlib.figure import Figure
# fig = Figure()
#-- ...but we want to use it interactive for a quick example, so
#-- we'll do it this way
fig, axes = plt.subplots(nrows=4, ncols=4)
for i, ax in enumerate(axes.flat, start=1):
ax.set_title('Test Axes {}'.format(i))
ax.set_xlabel('X axis')
ax.set_ylabel('Y axis')
plt.show()
import matplotlib.pyplot as plt
fig, axes = plt.subplots(nrows=4, ncols=4)
for i, ax in enumerate(axes.flat, start=1):
ax.set_title('Test Axes {}'.format(i))
ax.set_xlabel('X axis')
ax.set_ylabel('Y axis')
fig.tight_layout()
plt.show()
I prefer to use two options, white spaces and empty:
test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();
test = test.Where(x => !string.IsNullOrWhiteSpace(x)).ToArray();
All settings listed here are correct, but here are the most optimal and sufficient solution:
[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
character-set-server = utf8
collation-server = utf8_unicode_ci
[client]
default-character-set = utf8
Add these to /etc/mysql/my.cnf
.
Please note, I choose utf8_unicode_ci type of collation due to the performance issue.
The result is:
mysql> SHOW VARIABLES LIKE 'character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
mysql> SHOW VARIABLES LIKE 'collation%';
+----------------------+-----------------+
| Variable_name | Value |
+----------------------+-----------------+
| collation_connection | utf8_unicode_ci |
| collation_database | utf8_unicode_ci |
| collation_server | utf8_unicode_ci |
+----------------------+-----------------+
And this is when you connect as non-SUPER user!
For example, the difference between connection as SUPER and non-SUPER user (of course in case of utf8_unicode_ci collation):
user with SUPER priv.:
mysql> SHOW VARIABLES LIKE 'collation%';
+----------------------+-----------------+
| Variable_name | Value |
+----------------------+-----------------+
| collation_connection | utf8_general_ci | <---
| collation_database | utf8_unicode_ci |
| collation_server | utf8_unicode_ci |
+----------------------+-----------------+
user with non-SUPER priv.:
mysql> SHOW VARIABLES LIKE 'collation%';
+----------------------+-----------------+
| Variable_name | Value |
+----------------------+-----------------+
| collation_connection | utf8_unicode_ci |
| collation_database | utf8_unicode_ci |
| collation_server | utf8_unicode_ci |
+----------------------+-----------------+
I wrote a comprehensive article (rus) explaining in details why you should use one or the other option. All types of Character Sets and Collations are considered: for server, for database, for connection, for table and even for column.
I hope this and the article will help to clarify unclear moments.
Assuming you're on at least 3.2, there's a built in for this:
int.from_bytes( bytes, byteorder, *, signed=False )
...
The argument bytes must either be a bytes-like object or an iterable producing bytes.
The byteorder argument determines the byte order used to represent the integer. If byteorder is "big", the most significant byte is at the beginning of the byte array. If byteorder is "little", the most significant byte is at the end of the byte array. To request the native byte order of the host system, use sys.byteorder as the byte order value.
The signed argument indicates whether two’s complement is used to represent the integer.
## Examples:
int.from_bytes(b'\x00\x01', "big") # 1
int.from_bytes(b'\x00\x01', "little") # 256
int.from_bytes(b'\x00\x10', byteorder='little') # 4096
int.from_bytes(b'\xfc\x00', byteorder='big', signed=True) #-1024
It is impossible for both (?=foo)
and (?=baz)
to match at the same time. It would require the next character to be both f
and b
simultaneously which is impossible.
Perhaps you want this instead:
(?=.*foo)(?=.*baz)
This says that foo
must appear anywhere and baz
must appear anywhere, not necessarily in that order and possibly overlapping (although overlapping is not possible in this specific case because the letters themselves don't overlap).
As others have mentioned here, conventions should be a tool for adding to the ease of use and readability. Not as a shackle or a club to torture developers.
That said, my personal preference is to use singular names for both tables and columns. This probably comes from my programming background. Class names are generally singular unless they are some sort of collection. In my mind I am storing or reading individual records in the table in question, so singular makes sense to me.
This practice also allows me to reserve plural table names for those that store many-to-many relationships between my objects.
I try to avoid reserved words in my table and column names, as well. In the case in question here it makes more sense to go counter to the singular convention for Users to avoid the need to encapsulate a table that uses the reserved word of User.
I like using prefixes in a limited manner (tbl for table names, sp_ for proc names, etc), though many believe this adds clutter. I also prefer CamelBack names to underscores because I always end up hitting the + instead of _ when typing the name. Many others disagree.
Here is another good link for naming convention guidelines: http://www.xaprb.com/blog/2008/10/26/the-power-of-a-good-sql-naming-convention/
Remember that the most important factor in your convention is that it make sense to the people interacting with the database in question. There is no "One Ring to Rule Them All" when it comes to naming conventions.
I had this error because in my test I had two expectations, one on a mock and one on concrete type
MyClass cls = new MyClass();
MyClass cls2 = Mockito.mock(Myclass.class);
when(foo.bar(cls)).thenReturn(); // cls is not actually a mock
when(foo.baz(cls2)).thenReturn();
I fixed it by changing cls to be a mock as well
another option:
if you use PowerShell, you can find out like:
PS C:\Users\Pravat> ([system.reflection.assembly]::loadfile("C:\Program Files (x86)\MySQL\Connector NET 6.6.5\Assemblies\v4.0\MySql.Data.dll")).FullName
like
PS C:\Users\Pravat> ([system.reflection.assembly]::loadfile("dll full path")).FullName
and will appear like
MySql.Data, Version=6.6.5.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d
I have done something like this and it's working for me
$('#fileInput').val(null);
Okay. So this is a very old question and has great answers from that time. But a lot has changed since then.
Now, in 2020, if you are working with Kotlin and want to change the fragment then you can do the following.
In your app level build.gradle
file add the following,
dependencies {
def fragment_version = "1.2.5"
// Kotlin
implementation "androidx.fragment:fragment-ktx:$fragment_version"
// Testing Fragments in Isolation
debugImplementation "androidx.fragment:fragment-testing:$fragment_version"
}
In your activity
supportFragmentManager.commit {
replace(R.id.frame_layout, YourFragment.newInstance(), "Your_TAG")
addToBackStack(null)
}

If all else fails:
While writing queries using inner joins the records will fetches from both tables if the condition satisfied on both tables, i.e. exact match of the common column in both tables.
While writing query using cross join the result is like cartesian product of the no of records in both tables. example if table1 contains 2 records and table2 contains 3 records then result of the query is 2*3 = 6 records.
So dont go for cross join until you need that.
Indeed there is.
chmod a+x
is relative to the current state and just sets the x
flag. So a 640 file becomes 751 (or 750?), a 644 file becomes 755.
chmod 755
, however, sets the mask as written: rwxr-xr-x
, no matter how it was before. It is equivalent to chmod u=rwx,go=rx
.
In python:
('<MY_TOKEN>')
is equivalent to
'<MY_TOKEN>'
And requests interprets
('TOK', '<MY_TOKEN>')
As you wanting requests to use Basic Authentication and craft an authorization header like so:
'VE9LOjxNWV9UT0tFTj4K'
Which is the base64 representation of 'TOK:<MY_TOKEN>'
To pass your own header you pass in a dictionary like so:
r = requests.get('<MY_URI>', headers={'Authorization': 'TOK:<MY_TOKEN>'})
This way you can create Observable from data, in my case I need to maintain shopping cart:
service.ts
export class OrderService {
cartItems: BehaviorSubject<Array<any>> = new BehaviorSubject([]);
cartItems$ = this.cartItems.asObservable();
// I need to maintain cart, so add items in cart
addCartData(data) {
const currentValue = this.cartItems.value; // get current items in cart
const updatedValue = [...currentValue, data]; // push new item in cart
if(updatedValue.length) {
this.cartItems.next(updatedValue); // notify to all subscribers
}
}
}
Component.ts
export class CartViewComponent implements OnInit {
cartProductList: any = [];
constructor(
private order: OrderService
) { }
ngOnInit() {
this.order.cartItems$.subscribe(items => {
this.cartProductList = items;
});
}
}
function chkicon(num,allsize) {
var flagicon = document.getElementById("flagicon"+num).value;
if(flagicon=="plus"){
//alert("P== "+flagicon);
for (var i = 0; i < allsize; i++) {
if(document.getElementById("flagicon"+i).value !=""){
document.getElementById("flagicon"+i).value = "plus";
document.images["pic"+i].src = "../images/plus.gif";
}
}
document.images["pic"+num].src = "../images/minus.gif";
document.getElementById("flagicon"+num).value = "minus";
}else if(flagicon=="minus"){
//alert("M== "+flagicon);
document.images["pic"+num].src = "../images/plus.gif";
document.getElementById("flagicon"+num).value = "plus";
}else{
for (var i = 0; i < allsize; i++) {
if(document.getElementById("flagicon"+i).value !=""){
document.getElementById("flagicon"+i).value = "plus";
document.images["pic"+i].src = "../images/plus.gif";
}
}
}
}
I was dealing with DateTimeOffset
and unfortunately the "o" prints out "+0000" not "Z".
So I ended up with:
dateTimeOffset.UtcDateTime.ToString("o")

with Regular Expressions enabledIf you want to visualize your dependencies in a graph you can use gradle-dependency-graph-generator plugin.
Generally the output of this plugin can be found in build/reports/dependency-graph directory and it contains three files (.dot|.png|.svg) if you are using the 0.5.0 version of the plugin.
Example of dependences graph in a real app (Chess Clock):
This also works:
var number = 12354987;_x000D_
console.log(String(number).split('').map(Number));
_x000D_
One possibility:
myArray = myArray.filter(function( obj ) {
return obj.field !== 'money';
});
Please note that filter
creates a new array. Any other variables referring to the original array would not get the filtered data although you update your original variable myArray
with the new reference. Use with caution.
if you want to give the space between layout .this is the way to use space. if you remove margin it will not appear.use of text inside space to appear is not a good approach. hope that helps.
<Space
android:layout_width="match_content"
android:layout_height="wrap_content"
android:layout_margin="2sp" />
Try this:
USE master;
GO;
GRANT ADMINISTER BULK OPERATIONS TO shira;
My experience with MATMUL and DOT
I was constantly getting "ValueError: Shape of passed values is (200, 1), indices imply (200, 3)" when trying to use MATMUL. I wanted a quick workaround and found DOT to deliver the same functionality. I don't get any error using DOT. I get the correct answer
with MATMUL
X.shape
>>>(200, 3)
type(X)
>>>pandas.core.frame.DataFrame
w
>>>array([0.37454012, 0.95071431, 0.73199394])
YY = np.matmul(X,w)
>>> ValueError: Shape of passed values is (200, 1), indices imply (200, 3)"
with DOT
YY = np.dot(X,w)
# no error message
YY
>>>array([ 2.59206877, 1.06842193, 2.18533396, 2.11366346, 0.28505879, …

C++11 update to a very old question: Print variable type in C++.
The accepted (and good) answer is to use typeid(a).name()
, where a
is a variable name.
Now in C++11 we have decltype(x)
, which can turn an expression into a type. And decltype()
comes with its own set of very interesting rules. For example decltype(a)
and decltype((a))
will generally be different types (and for good and understandable reasons once those reasons are exposed).
Will our trusty typeid(a).name()
help us explore this brave new world?
No.
But the tool that will is not that complicated. And it is that tool which I am using as an answer to this question. I will compare and contrast this new tool to typeid(a).name()
. And this new tool is actually built on top of typeid(a).name()
.
The fundamental issue:
typeid(a).name()
throws away cv-qualifiers, references, and lvalue/rvalue-ness. For example:
const int ci = 0;
std::cout << typeid(ci).name() << '\n';
For me outputs:
i
and I'm guessing on MSVC outputs:
int
I.e. the const
is gone. This is not a QOI (Quality Of Implementation) issue. The standard mandates this behavior.
What I'm recommending below is:
template <typename T> std::string type_name();
which would be used like this:
const int ci = 0;
std::cout << type_name<decltype(ci)>() << '\n';
and for me outputs:
int const
<disclaimer>
I have not tested this on MSVC. </disclaimer>
But I welcome feedback from those who do.
The C++11 Solution
I am using __cxa_demangle
for non-MSVC platforms as recommend by ipapadop in his answer to demangle types. But on MSVC I'm trusting typeid
to demangle names (untested). And this core is wrapped around some simple testing that detects, restores and reports cv-qualifiers and references to the input type.
#include <type_traits>
#include <typeinfo>
#ifndef _MSC_VER
# include <cxxabi.h>
#endif
#include <memory>
#include <string>
#include <cstdlib>
template <class T>
std::string
type_name()
{
typedef typename std::remove_reference<T>::type TR;
std::unique_ptr<char, void(*)(void*)> own
(
#ifndef _MSC_VER
abi::__cxa_demangle(typeid(TR).name(), nullptr,
nullptr, nullptr),
#else
nullptr,
#endif
std::free
);
std::string r = own != nullptr ? own.get() : typeid(TR).name();
if (std::is_const<TR>::value)
r += " const";
if (std::is_volatile<TR>::value)
r += " volatile";
if (std::is_lvalue_reference<T>::value)
r += "&";
else if (std::is_rvalue_reference<T>::value)
r += "&&";
return r;
}
The Results
With this solution I can do this:
int& foo_lref();
int&& foo_rref();
int foo_value();
int
main()
{
int i = 0;
const int ci = 0;
std::cout << "decltype(i) is " << type_name<decltype(i)>() << '\n';
std::cout << "decltype((i)) is " << type_name<decltype((i))>() << '\n';
std::cout << "decltype(ci) is " << type_name<decltype(ci)>() << '\n';
std::cout << "decltype((ci)) is " << type_name<decltype((ci))>() << '\n';
std::cout << "decltype(static_cast<int&>(i)) is " << type_name<decltype(static_cast<int&>(i))>() << '\n';
std::cout << "decltype(static_cast<int&&>(i)) is " << type_name<decltype(static_cast<int&&>(i))>() << '\n';
std::cout << "decltype(static_cast<int>(i)) is " << type_name<decltype(static_cast<int>(i))>() << '\n';
std::cout << "decltype(foo_lref()) is " << type_name<decltype(foo_lref())>() << '\n';
std::cout << "decltype(foo_rref()) is " << type_name<decltype(foo_rref())>() << '\n';
std::cout << "decltype(foo_value()) is " << type_name<decltype(foo_value())>() << '\n';
}
and the output is:
decltype(i) is int
decltype((i)) is int&
decltype(ci) is int const
decltype((ci)) is int const&
decltype(static_cast<int&>(i)) is int&
decltype(static_cast<int&&>(i)) is int&&
decltype(static_cast<int>(i)) is int
decltype(foo_lref()) is int&
decltype(foo_rref()) is int&&
decltype(foo_value()) is int
Note (for example) the difference between decltype(i)
and decltype((i))
. The former is the type of the declaration of i
. The latter is the "type" of the expression i
. (expressions never have reference type, but as a convention decltype
represents lvalue expressions with lvalue references).
Thus this tool is an excellent vehicle just to learn about decltype
, in addition to exploring and debugging your own code.
In contrast, if I were to build this just on typeid(a).name()
, without adding back lost cv-qualifiers or references, the output would be:
decltype(i) is int
decltype((i)) is int
decltype(ci) is int
decltype((ci)) is int
decltype(static_cast<int&>(i)) is int
decltype(static_cast<int&&>(i)) is int
decltype(static_cast<int>(i)) is int
decltype(foo_lref()) is int
decltype(foo_rref()) is int
decltype(foo_value()) is int
I.e. Every reference and cv-qualifier is stripped off.
C++14 Update
Just when you think you've got a solution to a problem nailed, someone always comes out of nowhere and shows you a much better way. :-)
This answer from Jamboree shows how to get the type name in C++14 at compile time. It is a brilliant solution for a couple reasons:
Jamboree's answer doesn't quite lay everything out for VS, and I'm tweaking his code a little bit. But since this answer gets a lot of views, take some time to go over there and upvote his answer, without which, this update would never have happened.

I don't know of a way to force Chrome to not clear the Network debugger, but this might accomplish what you're looking for:
window.addEventListener("beforeunload", function() { debugger; }, false)
This will pause chrome before loading the new page by hitting a breakpoint.

have only one column but it should have 3 columns for it to be contented to the first result set
