Open IIS manager, select Application Pools, select the application pool you are using, click on Advanced Settings in the right-hand menu. Under General, set "Enable 32-Bit Applications" to "True".
The proper way to do this requires leveraging the SAM registry hive (on Windows 10, this requires NT AUTHORITY\SYSTEM
privileges). The information you require is in the the key: HKEY_LOCAL_MACHINE\SAM\SAM\Domains\Account\Users\Names
.
Each subkey is the username, and the default value in each subkey is a binary integer. This value (converted to decimal) actually corresponds to the last chunk of the of the SID.
Take "Administrator" for example, by default it is associated with the integer 0x1f4 (or 500).
So, in theory you could take the build a list of SIDS based on the subkey names of the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\ProfileList
key and/or HKEY_USERS
key, parse out the the value after the last hyphen (-), and compare that to the info from the SAM hive.
If you don't have NT AUTHORITY\SYSTEM
privileges, the next best way to approach this may be to follow the other method described in the answers here.
If you could not set your application autostart you can try to paste this code to manifest

or delete manifest I had found it in my application
You're looking for the cunningly named Registry.GetValue

When installing Python 3.4 the "Add python.exe to Path" came up unselected. Re-installed with this selected and problem resolved.
If memory serves correct, the reg add
command will NOT create the entire directory path if it does not exist. Meaning that if any of the parent registry keys do not exist then they must be created manually one by one. It is really annoying, I know! Example:
@echo off
reg add "HKCU\Software\Policies"
reg add "HKCU\Software\Policies\Microsoft"
reg add "HKCU\Software\Policies\Microsoft\Internet Explorer"
reg add "HKCU\Software\Policies\Microsoft\Internet Explorer\Control Panel"
reg add "HKCU\Software\Policies\Microsoft\Internet Explorer\Control Panel" /v HomePage /t REG_DWORD /d 1 /f

An application does not need to have any registry entry. In fact, many applications do not need to be installed at all. U3 USB sticks are a good example; the programs on them just run from the file system.
As noted, most good applications can be found via their uninstall registry key though. This is actually a pair of keys, per-user and per-machine (HKCU/HKLM - Piskvor mentioned only the HKLM one). It does not (always) give you the install directory, though.
If it's in HKCU, then you have to realise that HKEY_CURRENT_USER
really means "Current User". Other users have their own HKCU entries, and their own installed software. You can't find that. Reading every HKEY_USERS
hive is a disaster on corporate networks with roaming profiles. You really don't want to fetch 1000 accounts from your remote [US|China|Europe] office.
Even if an application is installed, and you know where, it may not have the same "version" notion you have. The best source is the "version" resource in the executables. That's indeed a plural, so you have to find all of them, extract version resources from all and in case of a conflict decid on something reasonable.
So - good luck. There are dozes of ways to fail.
This works for me:
Function Test-RegistryValue
{
param($regkey, $name)
$exists = Get-ItemProperty "$regkey\$name" -ErrorAction SilentlyContinue
Write-Host "Test-RegistryValue: $exists"
if (($exists -eq $null) -or ($exists.Length -eq 0))
{
return $false
}
else
{
return $true
}
}
edit (sorry I thought you wanted VBA).
Anytime you try to read a non-existent value from the registry, you get back a Null. Thus all you have to do is check for a Null value.
Use IsNull
not IsEmpty
.
Const HKEY_LOCAL_MACHINE = &H80000002
strComputer = "."
Set objRegistry = GetObject("winmgmts:\\" & _
strComputer & "\root\default:StdRegProv")
strKeyPath = "SOFTWARE\Microsoft\Windows NT\CurrentVersion"
strValueName = "Test Value"
objRegistry.GetStringValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,strValue
If IsNull(strValue) Then
Wscript.Echo "The registry key does not exist."
Else
Wscript.Echo "The registry key exists."
End If
I've come across many errors on Windows XP computers when using WMIC (eg due to corrupted files on machines). Hence imo best not to use WMIC for Win XP in code. No problems with WMIC on Win 7 though.
The answer posted by @m0nhawk doesn't seem to work as I test on a Windows 7 machine. Instead, using the following scripts would export/import the settings of putty:
::export

reg export HKCU\Software\SimonTatham %regfile% /y
popd
--
::import
@echo off
pushd %~dp0
set regfile=putty.reg
if exist %regfile% reg import %regfile%
popd
PhiLho has mentioned AutoRuns in passing, but I think it deserves elaboration.
It doesn't scan the whole registry, just the parts containing references to things which get loaded automatically (EXEs, DLLs, drivers etc.) which is probably what you are interested in. It doesn't track changes but can export to a text file, so you can run it before and after installation and do a diff.

Make sure you remove any java.exe
, javaw.exe
and javaws.exe
from your Windows\System32
folder and if you have an x64 system (Win 7 64 bits) also do the same under Windows\SysWOW64
.
If you can't find them at these locations, try deleting them from C:\ProgramData\Oracle\Java\javapath
.
You Could Do The same as abatishchev but without the UAC

Per pierce.jason's answer above, I had luck with:
Just create a new DWORD(32) under the Fusion key. Name the DWORD to LogFailures, and set it to value 1. Then restart IIS, refresh the page giving errors, and the assembly bind logs will show in the error message.
Once I updated my Java version to 8 as suggested by browser. However I had selected to uninstall previous Java 6 version I have been used for coding my projects. When I enter the command in "java -version" in cmd it showed 1.8 and I could not start eclipse IDE run on Java 1.6.
When I installed Java 8 update for the browser it had changed the "PATH" System variable appending "C:\ProgramData\Oracle\Java\javapath" to the beginning. Newly added path pointed to Java vesion 8. So I removed that path from "PATH" System variable and everything worked fine. :)

In my tests many of the approaches described here fail, I think because they rely on entries in the Windows registry that turn out to be not reliably present, depending on Office version, how it was installed etc. So a different approach is to not use the registry at all (Ok, so strictly that makes it not an answer to the question as posed), but instead write a script that:
Here's that approach implemented in VBScript:
Function OfficeBitness()
Dim VBACode, Excel, Wb, Module, Result
VBACode = "Function Is64bit() As Boolean" & vbCrLf & _
"#If Win64 Then" & vbCrLf & _
" Is64bit = True" & vbCrLf & _
"#End If" & vbCrLf & _
"End Function"
On Error Resume Next
Set Excel = CreateObject("Excel.Application")
Excel.Visible = False
Set Wb = Excel.Workbooks.Add
Set Module = Wb.VBProject.VBComponents.Add(1)
Module.CodeModule.AddFromString VBACode
Result = Excel.Run("Is64bit")
Set Module = Nothing
Wb.Saved = True
Wb.Close False
Excel.Quit
Set Excel = Nothing
On Error GoTo 0
If IsEmpty(Result) Then
OfficeBitness = 0 'Alternatively raise an error here?
ElseIf Result = True Then
OfficeBitness = 64
Else
OfficeBitness = 32
End If
End Function
PS. This approach runs more slowly than others here (about 2 seconds on my PC) but it might turn out to be more reliable across different installations and Office versions.
After some months, I've realised there may be a simpler approach, though still one that instantiates an Excel instance. The VBScript is:
Function OfficeBitness()
Dim Excel
Set Excel = CreateObject("Excel.Application")
Excel.Visible = False
If InStr(Excel.OperatingSystem,"64") > 0 Then
OfficeBitness = 64
Else
OfficeBitness = 32
End if
Excel.Quit
Set Excel = Nothing
End Function
This relies on the fact that Application.OperatingSystem
, when called from 32-bit Excel on 64-bit Windows returns Windows (32-bit) NT 10.00
or at least it does on my PC. But that's not mentioned in the docs.
The pair RegOpenKey and RegQueryKeyEx will do the trick.
If you use MFC CRegKey class is even more easier solution.
To remove the variable from the current command session without removing it permanently, use the regular built-in set
command - just put nothing after the equals sign:
set FOOBAR=
To confirm, run set
with no arguments and check the current environment. The variable should be missing from the list entirely.
Note: this will only remove the variable from the current environment - it will not persist the change to the registry. When a new command process is started, the variable will be back.
The problem is that IE won't reset the proxy settings until it either
Below is the code that I've used to get this working:
function Refresh-System
{
$signature = @'
[DllImport("wininet.dll", SetLastError = true, CharSet=CharSet.Auto)]
public static extern bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer, int dwBufferLength);
'@
$INTERNET_OPTION_SETTINGS_CHANGED = 39
$INTERNET_OPTION_REFRESH = 37
$type = Add-Type -MemberDefinition $signature -Name wininet -Namespace pinvoke -PassThru
$a = $type::InternetSetOption(0, $INTERNET_OPTION_SETTINGS_CHANGED, 0, 0)
$b = $type::InternetSetOption(0, $INTERNET_OPTION_REFRESH, 0, 0)
return $a -and $b
}
This should work for you:
Dim oShell
Dim iValue
Set oShell = CreateObject("WScript.Shell")
iValue = oShell.RegRead("HKLM\SOFTWARE\SOMETHINGSOMETHING")
While executing multiple lines of code in R, you need to first select all the lines of code and then click on "Run". This error usually comes up when we don't select our statements and click on "Run".
I know the question is old and was answered correctly in few different ways but there is no answer as mine which I have used in similar situations. First approach (very basic):
IF (1=0)
BEGIN
PRINT 'it will not go there'
-- your script here
END
PRINT 'but it will here'
Second approach:
PRINT 'stop here'
RETURN
-- your script here
PRINT 'it will not go there'
You can test it easily by yourself to make sure it behave as expected.
I have had the same error. I added dependency on pom.xml (I am working with Maven)

css3-mediaqueries-js is probably what you are looking for: this script emulates media queries. However (from the script's site) it "doesn't work on @import
ed stylesheets (which you shouldn't use anyway for performance reasons). Also won't listen to the media attribute of the <link>
and <style>
elements".
In the same vein you have the simpler Respond.js, which enables only min-width
and max-width
media queries.
If you want content to be what ever you need to have inside a div, this did the job for me:

This gave me the error message

Did you try turning off DEP (Data Execution Prevention) for your application ?
Change only in two line and you are getting actually what you want.
$query = $this->db->get();
$ret = $query->row();
return $ret->campaign_id;
try it.
See for maximum numbers: http://dev.mysql.com/doc/refman/5.0/en/storage-requirements.html
TINYBLOB, TINYTEXT L + 1 bytes, where L < 2^8 (255 Bytes)
BLOB, TEXT L + 2 bytes, where L < 2^16 (64 Kilobytes)
MEDIUMBLOB, MEDIUMTEXT L + 3 bytes, where L < 2^24 (16 Megabytes)
LONGBLOB, LONGTEXT L + 4 bytes, where L < 2^32 (4 Gigabytes)
L is the number of bytes in your text field. So the maximum number of chars for text is 216-1 (using single-byte characters). Means 65 535 chars(using single-byte characters).
UTF-8/MultiByte encoding: using MultiByte encoding each character might consume more than 1 byte of space. For UTF-8 space consumption is between 1 to 4 bytes per char.
Someone might find this useful, I had a problem flattening array at some dimension, I would call it last dimension so for example, if I have array like:
array (
'germany' =>
array (
'cars' =>
array (
'bmw' =>
array (
0 => 'm4',
1 => 'x3',
2 => 'x8',
),
),
),
'france' =>
array (
'cars' =>
array (
'peugeot' =>
array (
0 => '206',
1 => '3008',
2 => '5008',
),
),
),
)
Or:
array (
'earth' =>
array (
'germany' =>
array (
'cars' =>
array (
'bmw' =>
array (
0 => 'm4',
1 => 'x3',
2 => 'x8',
),
),
),
),
'mars' =>
array (
'france' =>
array (
'cars' =>
array (
'peugeot' =>
array (
0 => '206',
1 => '3008',
2 => '5008',
),
),
),
),
)
For both of these arrays when I call method below I get result:
array (
0 =>
array (
0 => 'm4',
1 => 'x3',
2 => 'x8',
),
1 =>
array (
0 => '206',
1 => '3008',
2 => '5008',
),
)
So I am flattening to last array dimension which should stay the same, method below could be refactored to actually stop at any kind of level:
function flattenAggregatedArray($aggregatedArray) {
$final = $lvls = [];
$counter = 1;
$lvls[$counter] = $aggregatedArray;
$elem = current($aggregatedArray);
while ($elem){
while(is_array($elem)){
$counter++;
$lvls[$counter] = $elem;
$elem = current($elem);
}
$final[] = $lvls[$counter];
$elem = next($lvls[--$counter]);
while ( $elem == null){
if (isset($lvls[$counter-1])){
$elem = next($lvls[--$counter]);
}
else{
return $final;
}
}
}
}
I go with Mark Longair's solution and comments and recommend anyone reads those before acting, but I'd suggest the emphasis should be on
git branch -f <branchname> <commit>
Here is a scenario where I have needed to do this.
Develop on the wrong branch and hence need to reset it.
Cleanly develop and release some software.
Mistake: Accidentally stay on the release branch while developing further.
"OH NO! I accidentally developed on the release branch." The workspace is maybe cluttered with half changed files that represent work-in-progress and we really don't want to touch and mess with. We'd just like git to flip a few pointers to keep track of the current state and put that release branch back how it should be.
Create a branch for the development that is up to date holding the work committed so far and switch to it.
git branch development
git checkout development
Now we are in the problem situation and need its solution! Rectify the mistake (of taking the release branch forward with the development) and put the release branch back how it should be.
Correct the release branch to point back to the last real release.
git branch -f release release2
The release branch is now correct again, like this ...
git push -f <remote> <branch>
is well described in another thread, though the word "overwrite" in the title is misleading.
Force "git push" to overwrite remote files
You can use plus. For example:
var personAge = '24';
var personAge1 = (+personAge)
then you can see the new variable's type bytypeof personAge1
; which is number
.
@Ian Nelson: I'm wondering if others see the problem there.
Let's say you have split fields. That's 70 characters total, 35 for first name and 35 for last name. However, if you have one field, you neglect the space that separates first and last names, short changing you by 1 character. Sure, it's "only" one character, but that could make the difference between someone entering their full name and someone not. Therefore, I would change that suggestion to "35 characters for each of Given Name and Family Name, or 71 characters for a single field to hold the Full Name".
My guess is that byteArrayIn
doesn't contain valid image data.
Please give more information though:
byteArrayIn

$rootScope.$emit('setTitle', newVal.full_name);

if (scope.item)
scope.item.name = title;
else
scope.item = {name: title};
});
jar cvfe myjar.jar package.MainClass *.class
where MainClass

The Selenium
client bindings will try to locate the geckodriver
executable from the system PATH
. You will need to add the directory containing the executable to the system path.
On Unix systems you can do the following to append it to your system’s search path, if you’re using a bash-compatible shell:
export PATH=$PATH:/path/to/geckodriver
On Windows you need to update the Path system variable to add the full directory path to the executable. The principle is the same as on Unix.
All below configuration for launching latest firefox using any programming language binding is applicable for Selenium2
to enable Marionette explicitly. With Selenium 3.0 and later, you shouldn't need to do anything to use Marionette, as it's enabled by default.
To use Marionette in your tests you will need to update your desired capabilities to use it.
Java :
As exception is clearly saying you need to download latest geckodriver.exe
from here and set downloaded geckodriver.exe
path where it's exists in your computer as system property with with variable webdriver.gecko.driver
before initiating marionette driver and launching firefox as below :-
//if you didn't update the Path system variable to add the full directory path to the executable as above mentioned then doing this directly through code
System.setProperty("webdriver.gecko.driver", "path/to/geckodriver.exe");
//Now you can Initialize marionette driver to launch firefox
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new MarionetteDriver(capabilities);
And for Selenium3
use as :-
WebDriver driver = new FirefoxDriver();
If you're still in trouble follow this link as well which would help you to solving your problem
.NET :
var driver = new FirefoxDriver(new FirefoxOptions());
Python :
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
caps = DesiredCapabilities.FIREFOX
# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True
# Path to Firefox DevEdition or Nightly.
# Firefox 47 (stable) is currently not supported,
# and may give you a suboptimal experience.
#
# On Mac OS you must point to the binary executable
# inside the application package, such as
# /Applications/FirefoxNightly.app/Contents/MacOS/firefox-bin
caps["binary"] = "/usr/bin/firefox"
driver = webdriver.Firefox(capabilities=caps)
Ruby :
# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by directly passing marionette: true
# You might need to specify an alternate path for the desired version of Firefox
Selenium::WebDriver::Firefox::Binary.path = "/path/to/firefox"
driver = Selenium::WebDriver.for :firefox, marionette: true
JavaScript (Node.js) :
const webdriver = require('selenium-webdriver');
const Capabilities = require('selenium-webdriver/lib/capabilities').Capabilities;
var capabilities = Capabilities.firefox();
// Tell the Node.js bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.set('marionette', true);
var driver = new webdriver.Builder().withCapabilities(capabilities).build();
Using RemoteWebDriver
If you want to use RemoteWebDriver
in any language, this will allow you to use Marionette
in Selenium
Grid.
Python:
caps = DesiredCapabilities.FIREFOX
# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True
driver = webdriver.Firefox(capabilities=caps)
Ruby :
# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by using the Capabilities class
# You might need to specify an alternate path for the desired version of Firefox
caps = Selenium::WebDriver::Remote::Capabilities.firefox marionette: true, firefox_binary: "/path/to/firefox"
driver = Selenium::WebDriver.for :remote, desired_capabilities: caps
Java :
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
// Tell the Java bindings to use Marionette.

I had to uninstall some external components like Postsharp and Apex and then it worked. I also tried the chosen solution but it gave me more errors.
Per this other post: Insert all values of a..., you can do the following:
INSERT INTO new_table (Foo, Bar, Fizz, Buzz)
SELECT Foo, Bar, Fizz, Buzz
FROM initial_table
It's important to specify the column names as indicated by the other answers.

Redis is more powerful, more popular, and better supported than memcached. Memcached can only do a small fraction of the things Redis can do. Redis is better even where their features overlap.
For anything new, use Redis.
Both tools are powerful, fast, in-memory data stores that are useful as a cache. Both can help speed up your application by caching database results, HTML fragments, or anything else that might be expensive to generate.
When used for the same thing, here is how they compare using the original question's "Points to Consider":
Memcached is a simple volatile cache server. It allows you to store key/value pairs where the value is limited to being a string up to 1MB.
It's good at this, but that's all it does. You can access those values by their key at extremely high speed, often saturating available network or even memory bandwidth.
When you restart memcached your data is gone. This is fine for a cache. You shouldn't store anything important there.
If you need high performance or high availability there are 3rd party tools, products, and services available.
Redis can do the same jobs as memcached can, and can do them better.
Redis can act as a cache as well. It can store key/value pairs too. In redis they can even be up to 512MB.
You can turn off persistence and it will happily lose your data on restart too. If you want your cache to survive restarts it lets you do that as well. In fact, that's the default.
It's super fast too, often limited by network or memory bandwidth.
If one instance of redis/memcached isn't enough performance for your workload, redis is the clear choice. Redis includes cluster support and comes with high availability tools (redis-sentinel) right "in the box". Over the past few years redis has also emerged as the clear leader in 3rd party tooling. Companies like Redis Labs, Amazon, and others offer many useful redis tools and services. The ecosystem around redis is much larger. The number of large scale deployments is now likely greater than for memcached.
Redis is more than a cache. It is an in-memory data structure server. Below you will find a quick overview of things Redis can do beyond being a simple key/value cache like memcached. Most of redis' features are things memcached cannot do.
Redis is better documented than memcached. While this can be subjective, it seems to be more and more true all the time.
redis.io is a fantastic easily navigated resource. It lets you try redis in the browser and even gives you live interactive examples with each command in the docs.
There are now 2x as many stackoverflow results for redis as memcached. 2x as many Google results. More readily accessible examples in more languages. More active development. More active client development. These measurements might not mean much individually, but in combination they paint a clear picture that support and documentation for redis is greater and much more up-to-date.
By default redis persists your data to disk using a mechanism called snapshotting. If you have enough RAM available it's able to write all of your data to disk with almost no performance degradation. It's almost free!
In snapshot mode there is a chance that a sudden crash could result in a small amount of lost data. If you absolutely need to make sure no data is ever lost, don't worry, redis has your back there too with AOF (Append Only File) mode. In this persistence mode data can be synced to disk as it is written. This can reduce maximum write throughput to however fast your disk can write, but should still be quite fast.
There are many configuration options to fine tune persistence if you need, but the defaults are very sensible. These options make it easy to setup redis as a safe, redundant place to store data. It is a real database.
Memcached is limited to strings, but Redis is a data structure server that can serve up many different data types. It also provides the commands you need to make the most of those data types.
Simple text or binary values that can be up to 512MB in size. This is the only data type redis and memcached share, though memcached strings are limited to 1MB.
Redis gives you more tools for leveraging this datatype by offering commands for bitwise operations, bit-level manipulation, floating point increment/decrement support, range queries, and multi-key operations. Memcached doesn't support any of that.
Strings are useful for all sorts of use cases, which is why memcached is fairly useful with this data type alone.
Hashes are sort of like a key value store within a key value store. They map between string fields and string values. Field->value maps using a hash are slightly more space efficient than key->value maps using regular strings.
Hashes are useful as a namespace, or when you want to logically group many keys. With a hash you can grab all the members efficiently, expire all the members together, delete all the members together, etc. Great for any use case where you have several key/value pairs that need to grouped.
One example use of a hash is for storing user profiles between applications. A redis hash stored with the user ID as the key will allow you to store as many bits of data about a user as needed while keeping them stored under a single key. The advantage of using a hash instead of serializing the profile into a string is that you can have different applications read/write different fields within the user profile without having to worry about one app overriding changes made by others (which can happen if you serialize stale data).
Redis lists are ordered collections of strings. They are optimized for inserting, reading, or removing values from the top or bottom (aka: left or right) of the list.
Redis provides many commands for leveraging lists, including commands to push/pop items, push/pop between lists, truncate lists, perform range queries, etc.
Lists make great durable, atomic, queues. These work great for job queues, logs, buffers, and many other use cases.
Sets are unordered collections of unique values. They are optimized to let you quickly check if a value is in the set, quickly add/remove values, and to measure overlap with other sets.
These are great for things like access control lists, unique visitor trackers, and many other things. Most programming languages have something similar (usually called a Set). This is like that, only distributed.
Redis provides several commands to manage sets. Obvious ones like adding, removing, and checking the set are present. So are less obvious commands like popping/reading a random item and commands for performing unions and intersections with other sets.
Sorted Sets are also collections of unique values. These ones, as the name implies, are ordered. They are ordered by a score, then lexicographically.
This data type is optimized for quick lookups by score. Getting the highest, lowest, or any range of values in between is extremely fast.
If you add users to a sorted set along with their high score, you have yourself a perfect leader-board. As new high scores come in, just add them to the set again with their high score and it will re-order your leader-board. Also great for keeping track of the last time users visited and who is active in your application.
Storing values with the same score causes them to be ordered lexicographically (think alphabetically). This can be useful for things like auto-complete features.
Many of the sorted set commands are similar to commands for sets, sometimes with an additional score parameter. Also included are commands for managing scores and querying by score.
Redis has several commands for storing, retrieving, and measuring geographic data. This includes radius queries and measuring distances between points.
Technically geographic data in redis is stored within sorted sets, so this isn't a truly separate data type. It is more of an extension on top of sorted sets.
Like geo, these aren't completely separate data types. These are commands that allow you to treat string data as if it's either a bitmap or a hyperloglog.
Bitmaps are what the bit-level operators I referenced under Strings
are for. This data type was the basic building block for reddit's recent collaborative art project: r/Place.
HyperLogLog allows you to use a constant extremely small amount of space to count almost unlimited unique values with shocking accuracy. Using only ~16KB you could efficiently count the number of unique visitors to your site, even if that number is in the millions.
Commands in redis are atomic, meaning you can be sure that as soon as you write a value to redis that value is visible to all clients connected to redis. There is no wait for that value to propagate. Technically memcached is atomic as well, but with redis adding all this functionality beyond memcached it is worth noting and somewhat impressive that all these additional data types and features are also atomic.
While not quite the same as transactions in relational databases, redis also has transactions that use "optimistic locking" (WATCH/MULTI/EXEC).
Redis provides a feature called 'pipelining'. If you have many redis commands you want to execute you can use pipelining to send them to redis all-at-once instead of one-at-a-time.
Normally when you execute a command to either redis or memcached, each command is a separate request/response cycle. With pipelining, redis can buffer several commands and execute them all at once, responding with all of the responses to all of your commands in a single reply.
This can allow you to achieve even greater throughput on bulk importing or other actions that involve lots of commands.
Redis has commands dedicated to pub/sub functionality, allowing redis to act as a high speed message broadcaster. This allows a single client to publish messages to many other clients connected to a channel.
Redis does pub/sub as well as almost any tool. Dedicated message brokers like RabbitMQ may have advantages in certain areas, but the fact that the same server can also give you persistent durable queues and other data structures your pub/sub workloads likely need, Redis will often prove to be the best and most simple tool for the job.
You can kind of think of lua scripts like redis's own SQL or stored procedures. It's both more and less than that, but the analogy mostly works.
Maybe you have complex calculations you want redis to perform. Maybe you can't afford to have your transactions roll back and need guarantees every step of a complex process will happen atomically. These problems and many more can be solved with lua scripting.
The entire script is executed atomically, so if you can fit your logic into a lua script you can often avoid messing with optimistic locking transactions.
As mentioned above, redis includes built in support for clustering and is bundled with its own high availability tool called redis-sentinel
.
Without hesitation I would recommend redis over memcached for any new projects, or existing projects that don't already use memcached.
The above may sound like I don't like memcached. On the contrary: it is a powerful, simple, stable, mature, and hardened tool. There are even some use cases where it's a little faster than redis. I love memcached. I just don't think it makes much sense for future development.
Redis does everything memcached does, often better. Any performance advantage for memcached is minor and workload specific. There are also workloads for which redis will be faster, and many more workloads that redis can do which memcached simply can't. The tiny performance differences seem minor in the face of the giant gulf in functionality and the fact that both tools are so fast and efficient they may very well be the last piece of your infrastructure you'll ever have to worry about scaling.
There is only one scenario where memcached makes more sense: where memcached is already in use as a cache. If you are already caching with memcached then keep using it, if it meets your needs. It is likely not worth the effort to move to redis and if you are going to use redis just for caching it may not offer enough benefit to be worth your time. If memcached isn't meeting your needs, then you should probably move to redis. This is true whether you need to scale beyond memcached or you need additional functionality.
If you want a %
symbol in search_criteria
to be treated as a literal character rather than as a wildcard, escape it to [%]
... where name like '%' + replace(search_criteria, '%', '[%]') + '%'
Good solution from bmu. I think it's more readable to put the values inside the parentheses vs outside.
df['Values'] = np.where(df.Action == 'Sell',
df.Prices*df.Amount,
-df.Prices*df.Amount)
Using some pandas built in functions.
df['Values'] = np.where(df.Action.eq('Sell'),
df.Prices.mul(df.Amount),
-df.Prices.mul(df.Amount))
On IntelliJ IDEA platform you can use Java Decompiler IntelliJ Plugin. It allows you to display all the Java sources during your debugging process, even if you do not have them all. It is based on the famous tools JD-GUI.
How about doing this in a much more elegant way with nodejs-config module.
This module is able to set configuration environment based on your computer's name. After that when you request a configuration you will get environment specific value.
For example lets assume your have two development machines named pc1 and pc2 and a production machine named pc3. When ever you request configuration values in your code in pc1 or pc2 you must get "development" environment configuration and in pc3 you must get "production" environment configuration. This can be achieved like this:
Now create new config instance with following syntax.
var config = require('nodejs-config')(
__dirname, // an absolute path to your applications 'config' directory
{
development: ["pc1", "pc2"],
production: ["pc3"],
}
);
Now you can get any configuration value without worrying about the environment like this:
config.get('app').configurationKey;
As of now you still can't animate rotations with jQuery, but you can with CSS3 animations, then simply add and remove the class with jQuery to make the animation occur.
HTML
<img src="http://puu.sh/csDxF/2246d616d8.png" width="30" height="30"/>
CSS3
img {
-webkit-transform: rotate(-90deg);
-moz-transform: rotate(-90deg);
-o-transform: rotate(-90deg);
-ms-transform: rotate(-90deg);
transform: rotate(-90deg);
transition-duration:0.4s;
}
.rotate {
-webkit-transform: rotate(0deg);
-moz-transform: rotate(0deg);
-o-transform: rotate(0deg);
-ms-transform: rotate(0deg);
transform: rotate(0deg);
transition-duration:0.4s;
}
jQuery
$(document).ready(function() {
$("img").mouseenter(function() {
$(this).addClass("rotate");
});
$("img").mouseleave(function() {
$(this).removeClass("rotate");
});
});
For people who searched for php multidimensional array get values
and actually want to solve problem comes from getting one column value from a 2 dimensinal array (like me!), here's a much elegant way than using foreach
, which is array_column
For example, if I only want to get hotel_name
from the below array, and form to another array:
$hotels = [
[
'hotel_name' => 'Hotel A',
'info' => 'Hotel A Info',
],
[
'hotel_name' => 'Hotel B',
'info' => 'Hotel B Info',
]
];
I can do this using array_column
:
$hotel_name = array_column($hotels, 'hotel_name');
print_r($hotel_name); // Which will give me ['Hotel A', 'Hotel B']
For the actual answer for this question, it can also be beautified by array_column
and call_user_func_array('array_merge', $twoDimensionalArray);
Let's make the data in PHP:
$hotels = [
[
'hotel_name' => 'Hotel A',
'info' => 'Hotel A Info',
'rooms' => [
[
'room_name' => 'Luxury Room',
'bed' => 2,
'boards' => [
'board_id' => 1,
'price' => 200
]
],
[
'room_name' => 'Non Luxy Room',
'bed' => 4,
'boards' => [
'board_id' => 2,
'price' => 150
]
],
]
],
[
'hotel_name' => 'Hotel B',
'info' => 'Hotel B Info',
'rooms' => [
[
'room_name' => 'Luxury Room',
'bed' => 2,
'boards' => [
'board_id' => 3,
'price' => 900
]
],
[
'room_name' => 'Non Luxy Room',
'bed' => 4,
'boards' => [
'board_id' => 4,
'price' => 300
]
],
]
]
];
And here's the calculation:
$rooms = array_column($hotels, 'rooms');
$rooms = call_user_func_array('array_merge', $rooms);
$boards = array_column($rooms, 'boards');
foreach($boards as $board){
$board_id = $board['board_id'];
$price = $board['price'];
echo "Board ID is: ".$board_id." and price is: ".$price . "<br/>";
}
Which will give you the following result:
Board ID is: 1 and price is: 200
Board ID is: 2 and price is: 150
Board ID is: 3 and price is: 900
Board ID is: 4 and price is: 300
In my case I had two functions a()
and b()
. First was calling second and second was calling first one:
var i = 0;
function a() { b(); }
function b() {
i++;
if (i < 30) {
a();
}
}
a();
I resolved this using setTimeout
:
var i = 0;
function a() { b(); }
function b() {
i++;
if (i < 30) {
setTimeout( function() {
a();
}, 0);
}
}
a();
The second parameter must be a URI, not a domain name. i.e.
passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
passman.add_password(None, "http://api.foursquare.com/", username, password)
To permanently set the language syntax:
open settings.json
file
*) format all txt files with javascript formatting
"files.associations": {
"*.txt": "javascript"
}
*) format all unsaved files (untitled-1 etc) to javascript:
"files.associations": {
"untitled-*": "javascript"
}
If you not want include other function like 'ReDimPreserve' could use temporal matrix for resizing. On based to your code:
Dim n As Integer, m As Integer, i as Long, j as Long
Dim arrTemporal() as Variant
n = 1
m = 0
Dim arrCity() As String
ReDim arrCity(n, m)
n = n + 1
m = m + 1
'VBA automatically adapts the size of the receiving matrix.
arrTemporal = arrCity
ReDim arrCity(n, m)
'Loop for assign values to arrCity
For i = 1 To UBound(arrTemporal , 1)
For j = 1 To UBound(arrTemporal , 2)
arrCity(i, j) = arrTemporal (i, j)
Next
Next
If you not declare of type VBA assume that is Variant.
Dim n as Integer, m As Integer
It seems that you've omitted the value attribute in HTML markup.
Add it there as <input value="" ... >
.
Perhaps its more meaningful to think of a CTE as a substitute for a view used for a single query. But doesn't require the overhead, metadata, or persistence of a formal view. Very useful when you need to:
Here's a cut-and-paste example to play with:
WITH [cte_example] AS (
SELECT 1 AS [myNum], 'a num' as [label]
UNION ALL
SELECT [myNum]+1,[label]
FROM [cte_example]
WHERE [myNum] <= 10
)
SELECT * FROM [cte_example]
UNION
SELECT SUM([myNum]), 'sum_all' FROM [cte_example]
UNION
SELECT SUM([myNum]), 'sum_odd' FROM [cte_example] WHERE [myNum] % 2 = 1
UNION
SELECT SUM([myNum]), 'sum_even' FROM [cte_example] WHERE [myNum] % 2 = 0;
Enjoy
Depends on what your target browsers are. In newer ones it's as simple as:
-moz-box-shadow: 0 0 5px #fff;
-webkit-box-shadow: 0 0 5px #fff;
box-shadow: 0 0 5px #fff;
For older browsers you have to implement workarounds, e.g., based on this example, but you will most probably need extra mark-up.
Note: You should not edit the default settings, because they get reset on updates/upgrades. For customization, you should override any setting by using the user bindings.
On Mac:
This opens a document that you can edit the keybindings for Sublime.
If you search "ctrl+super+g"
you find this:
{ "keys": ["ctrl+super+g"], "command": "find_all_under" },
The standard equivalent of find -iname ... -exec mv -t dest {} +
for find
implementations that don't support -iname
or mv
implementations that don't support -t
is to use a shell to re-order the arguments:
find . -name '*.[cC][pP][pP]' -type f -exec sh -c '
exec mv "$@" /dest/dir/' sh {} +
By using -name '*.[cC][pP][pP]'
, we also avoid the reliance on the current locale to decide what's the uppercase version of c
or p
.
Note that +
, contrary to ;
is not special in any shell so doesn't need to be quoted (though quoting won't harm, except of course with shells like rc
that don't support \
as a quoting operator).
The trailing /
in /dest/dir/
is so that mv
fails with an error instead of renaming foo.cpp
to /dest/dir
in the case where only one cpp
file was found and /dest/dir
didn't exist or wasn't a directory (or symlink to directory).
no need to that, tomcat naturally extract the war file into a folder of the same name. you simply modify the desired file inside that folder (including .xml configuration files), that's all. technically no need to restart tomcat after applying the modifications
With Java 8 there is this API method to accomplish your requirement.
map.putIfAbsent(key, value)
If the specified key is not already associated with a value (or is mapped to null) associates it with the given value and returns null, else returns the current value.
You can do it with an confirm()

In order to detect mouseleave without taking in account the scroll bar and the autcomplete field or inspect :
document.addEventListener("mouseleave", function(event){
if(event.clientY <= 0 || event.clientX <= 0 || (event.clientX >= window.innerWidth || event.clientY >= window.innerHeight))
{
console.log("I'm out");
}
});
Conditions explanations:
event.clientY <= 0 is when the mouse leave from the top
event.clientX <= 0 is when the mouse leave from the left
event.clientX >= window.innerWidth is when the mouse leave from the right
event.clientY >= window.innerHeight is when the mouse leave from the bottom
======================== EDIT ===============================
document.addEventListener("mouseleave") seems to be not fired on new firefox version, mouseleave need to be attached to an element like body, or a child element.
I suggest to use instead
document.body.addEventListener("mouseleave")
Or
window.addEventListener("mouseout")
I found that, some of you found that the IP address you get is :::1 or 0.0.0.1
This is the problem because of you try to get IP from your own machine, and the confusion of C# that try to return IPv6.
So, I implement the answer from @Johna (https://stackoverflow.com/a/41335701/812720) and @David (https://stackoverflow.com/a/8597351/812720), Thanks to them!
and here to solution:
add Microsoft.AspNetCore.HttpOverrides Package in your References (Dependencies/Packages)
add this line in Startup.cs
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
// your current code
// start code to add
// to get ip address
app.UseForwardedHeaders(new ForwardedHeadersOptions
{
ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
});
// end code to add
}
to get IPAddress, use this code in any of your Controller.cs
IPAddress remoteIpAddress = Request.HttpContext.Connection.RemoteIpAddress;
string result = "";
if (remoteIpAddress != null)
{
// If we got an IPV6 address, then we need to ask the network for the IPV4 address
// This usually only happens when the browser is on the same machine as the server.
if (remoteIpAddress.AddressFamily == System.Net.Sockets.AddressFamily.InterNetworkV6)
{
remoteIpAddress = System.Net.Dns.GetHostEntry(remoteIpAddress).AddressList
.First(x => x.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork);
}
result = remoteIpAddress.ToString();
}
and now you can get IPv4 address from remoteIpAddress or result

Basically, you need to include a dummy variable on typings.d.ts, remove any "import * as $ from 'jquery" from your code, and then manually add a tag to jQuery script to your SPA html. This way, webpack won't be in your way, and you should be able to access the same global jQuery variable in all your scripts.
First you have to ensure that there is a SMTP server listening on port 25.
To look whether you have the service, you can try using TELNET client, such as:
C:\> telnet localhost 25
(telnet client by default is disabled on most recent versions of Windows, you have to add/enable the Windows component from Control Panel. In Linux/UNIX usually telnet client is there by default.
$ telnet localhost 25
If it waits for long then time out, that means you don't have the required SMTP service. If successfully connected you enter something and able to type something, the service is there.
If you don't have the service, you can use these:
If you are sure that you already have the service, may be the SMTP requires additional security credentials. If you can tell me what SMTP server listening on port 25 I may be able to tell you more.
@bhamby is correct. By leaving the microseconds off of your timestamp value, your query would only match on a usagetime of 2012-09-03 08:03:06.000000
If you don't have the complete timestamp value captured from a previous query, you can specify a ranged predicate that will match on any microsecond value for that time:
...WHERE id = 1 AND usagetime BETWEEN '2012-09-03 08:03:06' AND '2012-09-03 08:03:07'
or
...WHERE id = 1 AND usagetime >= '2012-09-03 08:03:06'
AND usagetime < '2012-09-03 08:03:07'
This is what I did for bulk update:
UPDATE tableName SET isDeleted = 1 where columnName in ('430903GW4j683537882','430903GW4j667075431','430903GW4j658444015')
I also faced same issue and i just executed below command.

Your solution is ok. only try it in this way:

so execute the xargs
only when grep return 0
, e.g. when found the string in some files.
Using ScrollView
is not very difficult. You can just add one to your layout and put whatever you want to scroll inside. ScrollView
only takes one child so if you want to put a few things inside then you should make the first thing be something like a LinearLayout
.
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!-- things to scroll -->
</LinearLayout>
</ScrollView>
If you want to scroll things horizontally, then use a HorizontalScrollView
.
As is talked about in this post, sometimes you want the ScrollView
content to fill the screen. For example, if you had some buttons at the end of a readme. You want the buttons to always be at the end of the text and at bottom of the screen, even if the text doesn't scroll.
If the content scrolls, everything is fine. However, if the content is smaller than the size of the screen, the buttons are not at the bottom.
This can be solved with a combination of using fillViewPort
on the ScrollView
and using a layout weight on the content. Using fillViewPort
makes the ScrollView
fill the parent area. Setting the layout_weight
on one of the views in the LinearLayout
makes that view expand to fill any extra space.
Here is the XML
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

once I need to fix the height of a particular valued row by using inline CSS as following..
<tr><td colspan="4" style="height: 10px;">xxxyyyzzz</td></tr>
This answer may come a bit late but I have found an acceptable solution. My approach is a bit similar to @Mani one but I think mine is a bit more easy to understand.
Putting it into global hook and into the component itself are not ideal, global hook checks every request so you will need to write a lot of conditions to check if it should be 404 and window.location.href
in the component creation is too late as the request has gone into the component already and then you take it out.
What I did is to have a dedicated url for 404 pages and have a path *
that for everything that not found.
{ path: '/:locale/404', name: 'notFound', component: () => import('pages/Error404.vue') },
{ path: '/:locale/*',
beforeEnter (to) {
window.location = `/${to.params.locale}/404`
}
}
You can ignore the :locale
as my site is using i18n so that I can make sure the 404 page is using the right language.
On the side note, I want to make sure my 404 page is returning httpheader 404 status code instead of 200 when page is not found. The solution above would just send you to a 404 page but you are still getting 200 status code.
To do this, I have my nginx rule to return 404 status code on location /:locale/404
server {
listen 80;
server_name localhost;
error_page 404 /index.html;
location ~ ^/.*/404$ {
root /usr/share/nginx/html;
internal;
}
location / {
root /usr/share/nginx/html;
index index.html index.htm;
try_files $uri $uri/ @rewrites;
}
location @rewrites {
rewrite ^(.+)$ /index.html last;
}
location = /50x.html {
root /usr/share/nginx/html;
}
}
why not using?
location.href='http://www.example.com';
<!DOCTYPE html>_x000D_
<html>_x000D_
_x000D_
<head>_x000D_
<script>_x000D_

How to do a redirect to another route with react-router?
For example, when a user clicks a link <Link to="/" />Click to route</Link>
react-router will look for /
and you can use Redirect to
and send the user somewhere else like the login route.
From the docs for ReactRouterTraining:
Rendering a
<Redirect>
will navigate to a new location. The new location will override the current location in the history stack, like server-side redirects (HTTP 3xx) do.
import { Route, Redirect } from 'react-router'
<Route exact path="/" render={() => (
loggedIn ? (
<Redirect to="/dashboard"/>
) : (
<PublicHomePage/>
)
)}/>
to: string, The URL to redirect to.
<Redirect to="/somewhere/else"/>
to: object, A location to redirect to.
<Redirect to={{
pathname: '/login',
search: '?utm=your+face',
state: { referrer: currentLocation }
}}/>
If you check Use option as meta key
in the keyboard tab of the preferences, then the default emacs style commands for forward- and backward-word and ?F
(Alt+F) and ?B
(Alt+B) respectively.
I'd recommend reading From Bash to Z-Shell. If you want to increase your bash/zsh prowess!
Be careful when using Application.Transpose with a huge number of values. If you transpose values to a column, excel will assume you are assuming you transposed them from rows.
Max Column Limit < Max Row Limit, and it will only display the first (Max Column Limit) values, and anithing after that will be "N/A"
I would use Different IDs but assign each DIV the same class.
<div id="c-1" class="countdown"></div>
<div id="c-2" class="countdown"></div>
This also has the added benefit of being able to reconstruct the IDs based off of the return of jQuery('.countdown').length
Ok what about adding multiple classes to each countdown timer. IE:
<div class="countdown c-1"></div>
<div class="countdown c-2"></div>
<div class="countdown c-1"></div>
That way you get the best of both worlds. It even allows repeat 'IDS'
In your nginx.conf file, add mime.types to your http
body like so:
http {
include /etc/nginx/mime.types;
include /etc/nginx/conf.d/*.conf;
}
Now go to the terminal and run the following to reload the server:
sudo nginx -s reload
Open your web browser and do a hard reload: Right click on the reload button and select hard reload. On Chrome you can do Ctrl+Shift+R

MDN suggests that there's a much cleaner way of doing this in modern browsers:
// Assuming we're listening for e.g. a 'change' event on `element`
// Create a new 'change' event
var event = new Event('change');
// Dispatch it.
element.dispatchEvent(event);
I've changed the java proxy settings to direct connection - and it works.

For everyone who is encountering this and wants to accept the risk to test it, there is a solution: go to Incognito mode in Chrome and you'll be able to open "Advanced" and click "Proceed to some.url".
This can be helpful if you need to check some website which you are maintaining yourself and just testing as a developer (and when you don't yet have proper development certificate configured).
Of course this is NOT FOR PEOPLE using a website in production where this error indicates that there is a problem with website security.
To remove the border-radius on the corners add this style to your custom.css file
.navbar-inner{

This worked for me. tail -nX
allows you to grab only the last X lines.
cat /proc/cpuinfo | awk '/^processor/{print $3}' | tail -1
If you have hyperthreading, this should work for grabbing the number of physical cores.
grep "^core id" /proc/cpuinfo | sort -u | wc -l
Python threads cannot take advantage of many cores. This is due to an internal implementation detail called the GIL (global interpreter lock) in the C implementation of python (cPython) which is almost certainly what you use.
The workaround is the multiprocessing
module http://www.python.org/dev/peps/pep-0371/ which was developed for this purpose.
Documentation: http://docs.python.org/library/multiprocessing.html
(Or use a parallel language.)
You need to add query.addEntity(SwitcherServiceSource.class) before calling the .list() on query.
For what it's worth, I've run into this on what was previously working code. I had added SELECT statements in a trigger for debug testing and forgot to remove them. Entity Framework / MVC doesnt play nice when other stuff is output to the "grid". Make sure to check for any rogue queries and remove them.
Normally I would agree with Yaakov Ellis but in this special case there is another viable solution:
Use two tables:
Table: Item
Columns: ItemID, Title, Content
Indexes: ItemID
Table: Tag
Columns: ItemID, Title
Indexes: ItemId, Title
This has some major advantages:
First it makes development much simpler: in the three-table solution for insert and update of item
you have to lookup the Tag
table to see if there are already entries. Then you have to join them with new ones. This is no trivial task.
Then it makes queries simpler (and perhaps faster). There are three major database queries which you will do: Output all Tags
for one Item
, draw a Tag-Cloud and select all items for one Tag Title.
All Tags for one Item:
3-Table:
SELECT Tag.Title
FROM Tag
JOIN ItemTag ON Tag.TagID = ItemTag.TagID
WHERE ItemTag.ItemID = :id
2-Table:
SELECT Tag.Title
FROM Tag
WHERE Tag.ItemID = :id
Tag-Cloud:
3-Table:
SELECT Tag.Title, count(*)
FROM Tag
JOIN ItemTag ON Tag.TagID = ItemTag.TagID
GROUP BY Tag.Title
2-Table:
SELECT Tag.Title, count(*)
FROM Tag
GROUP BY Tag.Title
Items for one Tag:
3-Table:
SELECT Item.*
FROM Item
JOIN ItemTag ON Item.ItemID = ItemTag.ItemID
JOIN Tag ON ItemTag.TagID = Tag.TagID
WHERE Tag.Title = :title
2-Table:
SELECT Item.*
FROM Item
JOIN Tag ON Item.ItemID = Tag.ItemID
WHERE Tag.Title = :title
But there are some drawbacks, too: It could take more space in the database (which could lead to more disk operations which is slower) and it's not normalized which could lead to inconsistencies.
The size argument is not that strong because the very nature of tags is that they are normally pretty small so the size increase is not a large one. One could argue that the query for the tag title is much faster in a small table which contains each tag only once and this certainly is true. But taking in regard the savings for not having to join and the fact that you can build a good index on them could easily compensate for this. This of course depends heavily on the size of the database you are using.
The inconsistency argument is a little moot too. Tags are free text fields and there is no expected operation like 'rename all tags "foo" to "bar"'.
So tldr: I would go for the two-table solution. (In fact I'm going to. I found this article to see if there are valid arguments against it.)
Use CSS styles with CSS Classes instead
CSS
.error {
border:2px solid red;
}
Now in Javascript
document.getElementById("fName").className = document.getElementById("fName").className + " error"; // this adds the error class
document.getElementById("fName").className = document.getElementById("fName").className.replace(" error", ""); // this removes the error class
The main reason I mention this is suppose you want to change the color of the errored element's border. If you choose your way you will may need to modify many places in code. If you choose my way you can simply edit the style sheet.
try - Add sensitive code catch - to handle exception finally - always executed whether exception caught or not. Associated with try -catch. Used to close the resource which we opened in try block throw - To handover our created exception to JVM manually. Used to throw customized exception throws - To delegate the responsibility of exception handling to caller method or main method.
The browser cannot give access to 3rd party cookies like those received from ajax requests for security reasons, however it takes care of those automatically for you!
For this to work you need to:
1) login with the ajax request from which you expect cookies to be returned:
$.ajax("https://example.com/v2/login", {
method: 'POST',
data: {login_id: user, password: password},
crossDomain: true,
success: login_success,
error: login_error
});
2) Connect with xhrFields: { withCredentials: true }
in the next ajax request(s) to use the credentials saved by the browser
$.ajax("https://example.com/v2/whatever", {
method: 'GET',
xhrFields: { withCredentials: true },
crossDomain: true,
success: whatever_success,
error: whatever_error
});
The browser takes care of these cookies for you even though they are not readable from the headers
nor the document.cookie
http://en.wikipedia.org/wiki/Post/Redirect/Get
The most common way to implement this pattern in ASP.Net is to use Response.Redirect(Request.RawUrl)
Consider the differences between Redirect and Transfer. Transfer really isn't telling the browser to forward to a clear form, it's simply returning a cleared form. That may or may not be what you want.
Response.Redirect() does not a waste round trip. If you post to a script that clears the form by Server.Transfer() and reload you will be asked to repost by most browsers since the last action was a HTTP POST. This may cause your users to unintentionally repeat some action, eg. place a second order which will have to be voided later.
To make it work you have to replace a run this line of code
serviceMetadata httpGetEnabled="true"/>
http instead of https
and security mode="None" />
Yet another method - create a filter function that returns True
for all desired tags:
def my_filter(tag):
return (tag.name == 'a' and
tag.parent.name == 'li' and
'test' in tag.parent['class'])
Then just call find_all
with the argument:
for a in soup(my_filter): # or soup.find_all(my_filter)
print a
SELECT owner, table_name
FROM dba_constraints
WHERE constraint_name = <<your constraint name>>
will give you the name of the table. If you don't have access to the DBA_CONSTRAINTS
view, ALL_CONSTRAINTS
or USER_CONSTRAINTS
should work as well.
You want to use DateTimeOffset class.
var date = new DateTimeOffset(2009, 9, 1, 0, 0, 0, 0, new TimeSpan(0L));
var stringDate = date.ToString("u");
sorry I missed your original formatting with the miliseconds
var stringDate = date.ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fff'Z'");
I am lost in all these samples but today I needed to load an external .js from my main .js and I did this:
document.write("<script src='https://www.google.com/recaptcha/api.js'></script>");
In Ruby, the condition and the then
part of an if
expression must be separated by either an expression separator (i.e. ;
or a newline) or the then
keyword.
So, all of these would work:
if @item.rigged then 'Yes' else 'No' end
if @item.rigged; 'Yes' else 'No' end
if @item.rigged
'Yes' else 'No' end
There is also a conditional operator in Ruby, but that is completely unnecessary. The conditional operator is needed in C, because it is an operator: in C, if
is a statement and thus cannot return a value, so if you want to return a value, you need to use something which can return a value. And the only things in C that can return a value are functions and operators, and since it is impossible to make if
a function in C, you need an operator.
In Ruby, however, if
is an expression. In fact, everything is an expression in Ruby, so it already can return a value. There is no need for the conditional operator to even exist, let alone use it.
BTW: it is customary to name methods which are used to ask a question with a question mark at the end, like this:
@item.rigged?
This shows another problem with using the conditional operator in Ruby:
@item.rigged? ? 'Yes' : 'No'
It's simply hard to read with the multiple question marks that close to each other.
You could use the node STOMP client. This would let you integrate with a variety of message queues including:
I haven't used this library before, so I can't vouch for its quality. But STOMP is a pretty simple protocol so I suspect you can hack it into submission if necessary.
Another option is to use beanstalkd with node. beanstalkd is a very fast "task queue" written in C that is very good if you don't need the feature flexibility of the brokers listed above.
I wanted the date to be shown in the type='time' field.
The normal conversion skips the zeros and the form field does not show the value and puts forth an error in the console saying the format needs to be yyyy-mm-dd.
Hence I added a small statement (check)?(true):(false) as follows:
makeShortDate=(date)=>{
yy=date.getFullYear()
mm=date.getMonth()
dd=date.getDate()
shortDate=`${yy}-${(mm<10)?0:''}${mm+1}-${(dd<10)?0:''}${dd}`;
return shortDate;
}
While you may be able to decompile your APK
file, you will likely hit one big issue:
it's not going to return the code you wrote. It is instead going to return whatever the compiler inlined, with variables given random names, as well as functions given random names. It could take significantly more time to try to decompile and restore it into the code you had, than it will be to start over.
Sadly, things like this have killed many projects.
For the future, I highly recommend learning a Version Control System, like CVS, SVN and git etc.
and how to back it up.
You don't add links to style sheets. They are for describing the style of the page. You would change your mark-up or add JavaScript to navigate when the image is clicked.
Based only on your style you would have:
<a href="home.com" id="logo"></a>
Update Sept 2017: fs-promise
has been deprecated in favour of fs-extra
.
I haven't used it, but you could look into fs-promise. It's a node module that:
Proxies all async fs methods exposing them as Promises/A+ compatible promises (when, Q, etc). Passes all sync methods through as values.
The accepted answer is not perfect. The line that was printed first will stay there and if your second print does not cover the entire new line, you will end up with garbage text.
To illustrate the problem save this code as a script and run it (or just take a look):
import time
n = 100
for i in range(100):
for j in range(100):
print("Progress {:2.1%}".format(j / 100), end="\r")
time.sleep(0.01)
print("Progress {:2.1%}".format(i / 100))
The output will look something like this:
Progress 0.0%%
Progress 1.0%%
Progress 2.0%%
Progress 3.0%%
What works for me is to clear the line before leaving a permanent print. Feel free to adjust to your specific problem:
import time
ERASE_LINE = '\x1b[2K' # erase line command
n = 100
for i in range(100):
for j in range(100):
print("Progress {:2.1%}".format(j / 100), end="\r")
time.sleep(0.01)
print(ERASE_LINE + "Progress {:2.1%}".format(i / 100)) # clear the line first
And now it prints as expected:
Progress 0.0%
Progress 1.0%
Progress 2.0%
Progress 3.0%
I had a similar situation where a download needed to stay active overnight and required a key press that refreshed my connection. I also found that the mouse move does not work. However, using notepad and a send key function appears to have done the trick. I send a space instead of a "." because if there is a [yes/no] popup, it will automatically click the default response using the spacebar. Here is the code used.
param($minutes = 120)
$myShell = New-Object -com "Wscript.Shell"
for ($i = 0; $i -lt $minutes; $i++) {
Start-Sleep -Seconds 30
$myShell.sendkeys(" ")
}
This function will work for the designated 120 minutes (2 Hours), but can be modified for the timing desired by increasing or decreasing the seconds of the input, or increasing or decreasing the assigned value of the minutes parameter.
Just run the script in powershell ISE, or powershell, and open notepad. A space will be input at the specified interval for the desired length of time ($minutes).
Good Luck!
I had made a web app that shows GitHub release statistics in a clean format: https://hanadigital.github.io/grev/
the issue is that a DataTemplate isn't part of an element its applied to it.
this means if you bind to the template you're binding to something that has no context.
however if you put a element inside the template then when that element is applied to the parent it gains a context and the binding then works
so this will not work
<DataTemplate >
<DataTemplate.Resources>
<CollectionViewSource x:Key="projects" Source="{Binding Projects}" >
but this works perfectly
<DataTemplate >
<GroupBox Header="Projects">
<GroupBox.Resources>
<CollectionViewSource x:Key="projects" Source="{Binding Projects}" >
because after the datatemplate is applied the groupbox is placed in the parent and will have access to its Context
so all you have to do is remove the style from the template and move it into an element in the template
note that the context for a itemscontrol is the item not the control ie ComboBoxItem for ComboBox not the ComboBox itself in which case you should use the controls ItemContainerStyle instead
In my case I had the same error but my mistake was that I didn't declare my Toolbar.
So, before I use getSupportActionBar I had to find my toolbar and set the actionBar
appbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(appbar);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_nav_menu);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
Consider normalizing to E.164 format. For full international support, you'd need a VARCHAR of 15 digits.

From the docs:
from .. import scriptA
You can do this in packages, but not in scripts you run directly. From the link above:
Note that both explicit and implicit relative imports are based on the name of the current module. Since the name of the main module is always "__main__", modules intended for use as the main module of a Python application should always use absolute imports.
If you create a script that imports A.B.B, you won't receive the ValueError.
I can confirm that there is no XPath support within Beautiful Soup.
I am concerned about maintenance and upgrade problems down the road from customizing Bootstrap. I can document the customization steps today and hope that the person upgrading Bootstrap three years from now will find the documentation and reapply the steps (that may or may not work at that point). An argument can be made either way, I suppose, but I prefer keeping any customizations in my code.
I don't quite understand how Seb33300's approach can work, though. It certainly did not work with Bootstrap 4.0.3. For the nav bar to expand at 1200 instead of 768, rules for both media queries must be overridden to prevent expanding at 768 and force expanding at 1200.
I have a longer menu that would wrap on the iPad in Portrait mode. The following keeps the menu collapsed until the 1200 breakpoint:
@media (min-width: 768px) {
.navbar-header {
float: none; }
.navbar-toggle {
display: block; }
.navbar-fixed-top .navbar-collapse,
.navbar-static-top .navbar-collapse,
.navbar-fixed-bottom .navbar-collapse {
padding-right: 15px;
padding-left: 15px; }
.navbar-collapse.collapse {
display: none !important; }
.navbar-collapse.collapse.in {
display: block!important;
margin-top: 0px; }
}
@media (min-width: 1200px) {
.navbar-header {
float: left; }
.navbar-toggle {
display: none; }
.navbar-fixed-top .navbar-collapse,
.navbar-static-top .navbar-collapse,
.navbar-fixed-bottom .navbar-collapse {
display: block !important; }
}
10 weeks? Apparently you can do it in 24 hours!

EDIT:
Okay, so only 1 person found my answer amusing, but not amusing enough to upvote. The real question is how good do you need to be in 10 weeks?
If you get yourself a good book (the one linked above has some good reviews on Amazon), then in 10 weeks you might be proficient enough to do something useful in Java, but it takes years to become expert. Any time spent between 10 weeks and several years will move you from beginner towards expert.
Oh and read Teach Yourself Programming in Ten Years.
I just right-clicked, and opened with Visual Studio XXXX (in my case 2015). Then save it. Done.
My solution:
File jarToAdd = new File("/path/to/file");
new URLClassLoader(((URLClassLoader) ClassLoader.getSystemClassLoader()).getURLs()) {
@Override
public void addURL(URL url) {
super.addURL(url);
}
}.addURL(jarToAdd.toURI().toURL());
I tried the marked solution here first. It worked but it is kind hacky, and you need to redo it every time you update the gcc. I finally find a better solution by doing the followings:
Project
-> Properties
-> C/C++ General
-> Preprocessor Include Paths, Macros, etc.
Providers
-> CDT GCC built-in compiler settings
Use global provider shared between projects
(you can also modify the global provider if it fits your need)Command to get compiler specs
, add -std=c++11
at the endIndex
->Rebuild
Voila, easy and simple. Hopefully this helps.
Note: I am on Kepler. I am not sure if this works on earlier Eclipse.
I had similar issue with the index.html being cached by the browser or more tricky by middle cdn/proxies (F5 will not help you).
I looked for a solution which verifies 100% that the client has the latest index.html version, luckily I found this solution by Henrik Peinar:
https://blog.nodeswat.com/automagic-reload-for-clients-after-deploy-with-angular-4-8440c9fdd96c
The solution solve also the case where the client stays with the browser open for days, the client checks for updates on intervals and reload if newer version deployd.
The solution is a bit tricky but works like a charm:
ng cli -- prod
produces hashed files with one of them called main.[hash].jsSince Henrik Peinar solution was for angular 4, there were minor changes, I place also the fixed scripts here:
VersionCheckService :
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
@Injectable()
export class VersionCheckService {
// this will be replaced by actual hash post-build.js
private currentHash = '{{POST_BUILD_ENTERS_HASH_HERE}}';
constructor(private http: HttpClient) {}
/**
* Checks in every set frequency the version of frontend application
* @param url
* @param {number} frequency - in milliseconds, defaults to 30 minutes
*/
public initVersionCheck(url, frequency = 1000 * 60 * 30) {
//check for first time
this.checkVersion(url);
setInterval(() => {
this.checkVersion(url);
}, frequency);
}
/**
* Will do the call and check if the hash has changed or not
* @param url
*/
private checkVersion(url) {
// timestamp these requests to invalidate caches
this.http.get(url + '?t=' + new Date().getTime())
.subscribe(
(response: any) => {
const hash = response.hash;
const hashChanged = this.hasHashChanged(this.currentHash, hash);
// If new version, do something
if (hashChanged) {
// ENTER YOUR CODE TO DO SOMETHING UPON VERSION CHANGE
// for an example: location.reload();
// or to ensure cdn miss: window.location.replace(window.location.href + '?rand=' + Math.random());
}
// store the new hash so we wouldn't trigger versionChange again
// only necessary in case you did not force refresh
this.currentHash = hash;
},
(err) => {
console.error(err, 'Could not get version');
}
);
}
/**
* Checks if hash has changed.
* This file has the JS hash, if it is a different one than in the version.json
* we are dealing with version change
* @param currentHash
* @param newHash
* @returns {boolean}
*/
private hasHashChanged(currentHash, newHash) {
if (!currentHash || currentHash === '{{POST_BUILD_ENTERS_HASH_HERE}}') {
return false;
}
return currentHash !== newHash;
}
}
change to main AppComponent:
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
constructor(private versionCheckService: VersionCheckService) {
}
ngOnInit() {
console.log('AppComponent.ngOnInit() environment.versionCheckUrl=' + environment.versionCheckUrl);
if (environment.versionCheckUrl) {
this.versionCheckService.initVersionCheck(environment.versionCheckUrl);
}
}
}
The post-build script that makes the magic, post-build.js:
const path = require('path');
const fs = require('fs');
const util = require('util');
// get application version from package.json
const appVersion = require('../package.json').version;
// promisify core API's
const readDir = util.promisify(fs.readdir);
const writeFile = util.promisify(fs.writeFile);
const readFile = util.promisify(fs.readFile);
console.log('\nRunning post-build tasks');
// our version.json will be in the dist folder
const versionFilePath = path.join(__dirname + '/../dist/version.json');
let mainHash = '';
let mainBundleFile = '';
// RegExp to find main.bundle.js, even if it doesn't include a hash in it's name (dev build)
let mainBundleRegexp = /^main.?([a-z0-9]*)?.js$/;
// read the dist folder files and find the one we're looking for
readDir(path.join(__dirname, '../dist/'))
.then(files => {
mainBundleFile = files.find(f => mainBundleRegexp.test(f));
if (mainBundleFile) {
let matchHash = mainBundleFile.match(mainBundleRegexp);
// if it has a hash in it's name, mark it down
if (matchHash.length > 1 && !!matchHash[1]) {
mainHash = matchHash[1];
}
}
console.log(`Writing version and hash to ${versionFilePath}`);
// write current version and hash into the version.json file
const src = `{"version": "${appVersion}", "hash": "${mainHash}"}`;
return writeFile(versionFilePath, src);
}).then(() => {
// main bundle file not found, dev build?
if (!mainBundleFile) {
return;
}
console.log(`Replacing hash in the ${mainBundleFile}`);
// replace hash placeholder in our main.js file so the code knows it's current hash
const mainFilepath = path.join(__dirname, '../dist/', mainBundleFile);
return readFile(mainFilepath, 'utf8')
.then(mainFileData => {
const replacedFile = mainFileData.replace('{{POST_BUILD_ENTERS_HASH_HERE}}', mainHash);
return writeFile(mainFilepath, replacedFile);
});
}).catch(err => {
console.log('Error with post build:', err);
});
simply place the script in (new) build folder run the script using node ./build/post-build.js
after building dist folder using ng build --prod
For exceptions, I usually do
catch (Exception ex)
{
return InternalServerError(new ApplicationException("Something went wrong in this request. internal exception: " + ex.Message));
}
You need to do encode
on tmp[0]
, not on tmp
.
tmp
is not a string. It contains a (Unicode) string.
Try running type(tmp)
and print dir(tmp)
to see it for yourself.
To differentiate between scroll up/down in jQuery, you could use:
var mousewheelevt = (/Firefox/i.test(navigator.userAgent)) ? "DOMMouseScroll" : "mousewheel" //FF doesn't recognize mousewheel as of FF3.x
$('#yourDiv').bind(mousewheelevt, function(e){
var evt = window.event || e //equalize event object
evt = evt.originalEvent ? evt.originalEvent : evt; //convert to originalEvent if possible
var delta = evt.detail ? evt.detail*(-40) : evt.wheelDelta //check for detail first, because it is used by Opera and FF
if(delta > 0) {
//scroll up
}
else{
//scroll down
}
});
This method also works in divs that have overflow:hidden
.
I successfully tested it in FireFox, IE and Chrome.
I think this is what the OP really wants:
array = -1:0.1:10
for i=1:numel(array)
disp(array(i))
end
The following example for complex numbers should be self explanatory including the error message at the end
>>> x=complex(1,2)
>>> print x
(1+2j)
>>> y=complex(3,4)
>>> print y
(3+4j)
>>> z=x+y
>>> print x
(1+2j)
>>> print z
(4+6j)
>>> z=x*y
>>> print z
(-5+10j)
>>> z=x/y
>>> print z
(0.44+0.08j)
>>> print x.conjugate()
(1-2j)
>>> print x.imag
2.0
>>> print x.real
1.0
>>> print x>y
Traceback (most recent call last):
File "<pyshell#149>", line 1, in <module>
print x>y
TypeError: no ordering relation is defined for complex numbers
>>> print x==y
False
>>>
You could suppress the warning using error_reporting but the much better way is to fix your script in the first place.
If you don't know how, edit your question and show us the line in question and the warning that is displayed.
Set the "long" type of id instead of java.lang.Integer. And add getters and setters to your fields.
This is, in effect, a way to check whether the expression e can be evaluated to be 0, and if not, to fail the build.
The macro is somewhat misnamed; it should be something more like BUILD_BUG_OR_ZERO
, rather than ...ON_ZERO
. (There have been occasional discussions about whether this is a confusing name.)
You should read the expression like this:
sizeof(struct { int: -!!(e); }))
(e)
: Compute expression e
.
!!(e)
: Logically negate twice: 0
if e == 0
; otherwise 1
.
-!!(e)
: Numerically negate the expression from step 2: 0
if it was 0
; otherwise -1
.
struct{int: -!!(0);} --> struct{int: 0;}
: If it was zero, then we declare a struct with an anonymous integer bitfield that has width zero. Everything is fine and we proceed as normal.
struct{int: -!!(1);} --> struct{int: -1;}
: On the other hand, if it isn't zero, then it will be some negative number. Declaring any bitfield with negative width is a compilation error.
So we'll either wind up with a bitfield that has width 0 in a struct, which is fine, or a bitfield with negative width, which is a compilation error. Then we take sizeof
that field, so we get a size_t
with the appropriate width (which will be zero in the case where e
is zero).
Some people have asked: Why not just use an assert
?
keithmo's answer here has a good response:
These macros implement a compile-time test, while assert() is a run-time test.
Exactly right. You don't want to detect problems in your kernel at runtime that could have been caught earlier! It's a critical piece of the operating system. To whatever extent problems can be detected at compile time, so much the better.
I know this is old, BUT for anyone else looking:
Remove https:// from the hostname and add port 443 instead.
{
method: 'POST',
hostname: 'api.dropbox.com',
port: 443
}
This is a common problem which many have encountered, but luckily some smart minds like Ed Eliot's on his blog have posted their solutions online.
Basically what you do is make both divs/columns very tall by adding a padding-bottom: 100%
and then "trick the browser" into thinking they aren't that tall using margin-bottom: -100%
. It is better explained by Ed Eliot on his blog, which also includes many examples.
.container {_x000D_
overflow: hidden;_x000D_
}_x000D_
.column {_x000D_
float: left;_x000D_
margin: 20px;_x000D_
background-color: grey;_x000D_
padding-bottom: 100%;_x000D_
margin-bottom: -100%;_x000D_
}
_x000D_
<div class="container">_x000D_
_x000D_

If manually formatting JSON, there is a very handy validator here: jsonlint.com
Use double quotes instead of single quotes:
{
'project': 'a2ab6ef4-1a8c-40cd-b561-2112b6baffd6',
'franchise': '110bcca5-cc74-416a-9e2a-f90a8c5f63a0'
}
{
"project": "a2ab6ef4-1a8c-40cd-b561-2112b6baffd6",
"franchise": "18e899f6-dd71-41b7-8c45-5dc0919679ef"
}
Type in the Microsoft Visual Studio Command Prompt
: where svcutil.exe
. On my machine it is in: C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\SvcUtil.exe
Actually I don't see any nulls:
given:
static void Main()
{
string[] testArray = new string[]
{
"aa",
"ab",
"ac",
"ad",
"ab",
"af"
};
Array.Sort(testArray, StringComparer.InvariantCulture);
Array.ForEach(testArray, x => Console.WriteLine(x));
}
I obtained:
You could try stacking multiple blured shadows until the shadows look like a stroke, like so:
.shadowOutline {
text-shadow: 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black, 0 0 4px black;
}
Here's a fiddle: http://jsfiddle.net/GGUYY/
I mention it just in case someone's interested, although I wouldn't call it a solution because it fails in various ways:
If you develop in Visual Studio 2013 and 2015 versions, you can use their GPU Usage tool:
Moreover, it seems you can diagnose any application with it, not only Visual Studio Projects:
In addition to Visual Studio projects you can also collect GPU usage data on any loose .exe applications that you have sitting around. Just open the executable as a solution in Visual Studio and then start up a diagnostics session and you can target it with GPU usage. This way if you are using some type of engine or alternative development environment you can still collect data on it as long as you end up with an executable.

The onchange event doesn't fires when an element with the contentEditable attribute is changed, a suggested approach could be to add a button, to "save" the edition.
Check this plugin which handles the issue in that way:
Enclose your code with the html and body tags. Size attribute does not correspond to font-size and it looks like its domain does not go beyond value 7. Furthermore font tag is not supported in HTML5. Consider this code for your case

The octothorpe/number-sign/hashmark has a special significance in an URL, it normally identifies the name of a section of a document. The precise term is that the text following the hash is the anchor portion of an URL. If you use Wikipedia, you will see that most pages have a table of contents and you can jump to sections within the document with an anchor, such as:
https://en.wikipedia.org/wiki/Alan_Turing#Early_computers_and_the_Turing_test
https://en.wikipedia.org/wiki/Alan_Turing
identifies the page and Early_computers_and_the_Turing_test
is the anchor. The reason that Facebook and other Javascript-driven applications (like my own Wood & Stones) use anchors is that they want to make pages bookmarkable (as suggested by a comment on that answer) or support the back button without reloading the entire page from the server.
In order to support bookmarking and the back button, you need to change the URL. However, if you change the page portion (with something like window.location = 'http://raganwald.com';
) to a different URL or without specifying an anchor, the browser will load the entire page from the URL. Try this in Firebug or Safari's Javascript console. Load http://minimal-github.gilesb.com/raganwald
. Now in the Javascript console, type:
window.location = 'http://minimal-github.gilesb.com/raganwald';
You will see the page refresh from the server. Now type:
window.location = 'http://minimal-github.gilesb.com/raganwald#try_this';
Aha! No page refresh! Type:
window.location = 'http://minimal-github.gilesb.com/raganwald#and_this';
Still no refresh. Use the back button to see that these URLs are in the browser history. The browser notices that we are on the same page but just changing the anchor, so it doesn't reload. Thanks to this behaviour, we can have a single Javascript application that appears to the browser to be on one 'page' but to have many bookmarkable sections that respect the back button. The application must change the anchor when a user enters different 'states', and likewise if a user uses the back button or a bookmark or a link to load the application with an anchor included, the application must restore the appropriate state.
So there you have it: Anchors provide Javascript programmers with a mechanism for making bookmarkable, indexable, and back-button-friendly applications. This technique has a name: It is a Single Page Interface.
p.s. There is a fourth benefit to this technique: Loading page content through AJAX and then injecting it into the current DOM can be much faster than loading a new page. In addition to the speed increase, further tricks like loading certain portions in the background can be performed under the programmer's control.
p.p.s. Given all of that, the 'bang' or exclamation mark is a further hint to Google's web crawler that the exact same page can be loaded from the server at a slightly different URL. See Ajax Crawling. Another technique is to make each link point to a server-accessible URL and then use unobtrusive Javascript to change it into an SPI with an anchor.
Here's the key link again: The Single Page Interface Manifesto
When you populate your fields, you can check for the value:
<input type="radio" name="sex" value="Male" <?php echo ($sex=='Male')?'checked':'' ?>size="17">Male
<input type="radio" name="sex" value="Female" <?php echo ($sex=='Female')?'checked':'' ?> size="17">Female
Assuming that the value you return from your database is in the variable $sex
The checked property will preselect the value that match
If you want to convert an Array of digits to a single number just use:
Number(arrayOfDigits.join(''));
const arrayOfDigits = [1,2,3,4,5];
const singleNumber = Number(arrayOfDigits.join(''));
console.log(singleNumber); //12345
This one get everything between the "." characters. Please note this won't work for more complex URLs like "www.somesite.co.uk" Ideally the function would check for how many instances of the "." character and choose the substring accordingly.

I had the same issue. I had a backup of my C:\xampp\mysql\data
folder. But integrating it with the newly installed xampp
had issues. So I located the C:\xampp\mysql\bin\my.ini
file and directed innodb_data_home_dir = "C:/xampp/mysql/data"
to my backed-up data folder and it worked flawlessly.
You can do it in 2 ways that I am aware of.
1- <MyComponent text={<p>This is <strong>not</strong> working.</p>} />
And then do this
class MyComponent extends React.Component {
render () {
return (<div>{this.props.text}</div>)
}
}
Or second approach do it like this
2- <MyComponent><p>This is <strong>not</strong> working.</p><MyComponent/>
And then do this
class MyComponent extends React.Component {
render () {
return (<div>{this.props.children}</div>)
}
}
You can use closures to pass parameters:
iframe.document.addEventListener('click', function(event) {clic(this.id);}, false);
However, I recommend that you use a better approach to access your frame (I can only assume that you are using the DOM0 way of accessing frame windows by their name - something that is only kept around for backwards compatibility):
document.getElementById("myFrame").contentDocument.addEventListener(...);
About access
<ol class="viewer-nav">
<li *ngFor="let section of sections"
[attr.data-sectionvalue]="section.value"
(click)="get_data($event)">
{{ section.text }}
</li>
</ol>
And
get_data(event) {
console.log(event.target.dataset.sectionvalue)
}
If you want first 2 letters and last 2 letters of a string then you can use the following code:
name = "India"
name[0:2]="In"
names[-2:]="ia"
Have you tried using Form.ShowDialog() instead of Form.Show()?
ShowDialog shows your window as modal, which means you cannot interact with the parent form until it closes.
Change the button to
<button id="search">Search</button>
and add the following script
var url = '@Url.Action("DisplaySearchResults", "Search")';
$('#search').click(function() {
var keyWord = $('#Keyword').val();
$('#searchResults').load(url, { searchText: keyWord });
})
and modify the controller method to accept the search text
public ActionResult DisplaySearchResults(string searchText)
{
var model = // build list based on parameter searchText
return PartialView("SearchResults", model);
}
The jQuery .load
method calls your controller method, passing the value of the search text and updates the contents of the <div>
with the partial view.
Side note: The use of a <form>
tag and @Html.ValidationSummary()
and @Html.ValidationMessageFor()
are probably not necessary here. Your never returning the Index
view so ValidationSummary
makes no sense and I assume you want a null
search text to return all results, and in any case you do not have any validation attributes for property Keyword
so there is nothing to validate.
Edit
Based on OP's comments that SearchCriterionModel
will contain multiple properties with validation attributes, then the approach would be to include a submit button and handle the forms .submit()
event
<input type="submit" value="Search" />
var url = '@Url.Action("DisplaySearchResults", "Search")';
$('form').submit(function() {
if (!$(this).valid()) {
return false; // prevent the ajax call if validation errors
}
var form = $(this).serialize();
$('#searchResults').load(url, form);
return false; // prevent the default submit action
})
and the controller method would be
public ActionResult DisplaySearchResults(SearchCriterionModel criteria)
{
var model = // build list based on the properties of criteria
return PartialView("SearchResults", model);
}
A good seed initialisation can be done like this
Random rnd = new Random((int)DateTime.Now.Ticks);
The ticks will be unique and the cast into a int with probably a loose of value will be OK.
Maybe is late now but following Spacedman, did you try duplicate="strip" or any other option?
x=runif(1000)
y=runif(1000)
z=rnorm(1000)
s=interp(x,y,z,duplicate="strip")
surface3d(s$x,s$y,s$z,color="blue")
points3d(s)
If you do import foo
(inside bar.py
) and import bar
(inside foo.py
), it will work fine. By the time anything actually runs, both modules will be fully loaded and will have references to each other.
The problem is when instead you do from foo import abc
(inside bar.py
) and from bar import xyz
(inside foo.py
). Because now each module requires the other module to already be imported (so that the name we are importing exists) before it can be imported.
Late answering, probably everybody knows about yield
now, but some better documentation has come along.
Adapting an example from "Javascript's Future: Generators" by James Long for the official Harmony standard:
function * foo(x) {
while (true) {
x = x * 2;
yield x;
}
}
"When you call foo, you get back a Generator object which has a next method."
var g = foo(2);
g.next(); // -> 4
g.next(); // -> 8
g.next(); // -> 16
So yield
is kind of like return
: you get something back. return x
returns the value of x
, but yield x
returns a function, which gives you a method to iterate toward the next value. Useful if you have a potentially memory intensive procedure that you might want to interrupt during the iteration.
I had a similar problem and I solved it by:
Using <base href="/index.html">
in the index page
Using a catch all route middleware in my node/Express server as follows (put it after the router):
app.use(function(req, res) {
res.sendfile(__dirname + '/Public/index.html');
});
I think that should get you up and running.
If you use an apache server, you might want to mod_rewrite your links. It is not difficult to do. Just a few changes in the config files.
All that is assuming you have html5mode enabled on angularjs. Now. note that in angular 1.2, declaring a base url is not recommended anymore actually.
If the button tag is inside the div element who contains the modal, you can do something like:
<button class="btn btn-default" data-dismiss="modal" aria-label="Close">Cancel</button>
I think...
Search partial value:
SELECT id FROM table_name WHERE field_name REGEXP '"key_name":"([^"])*key_word([^"])*"';
Search exact word:
SELECT id FROM table_name WHERE field_name RLIKE '"key_name":"[[:<:]]key_word[[:>:]]"';
You could put static elements after the fields and show them, or you could inject the validation message dynamically. See the below example for how to inject dynamically.
This example also follows the best practice of setting focus to the blank field so user can easily correct the issue.
Note that you could easily genericize this to work with any label & field (for required fields anyway), instead of my example which specifically codes each validation.
Your fiddle is updated, see here: jsfiddle
The code:
$('form').on('submit', function (e) {
var focusSet = false;
if (!$('#email').val()) {
if ($("#email").parent().next(".validation").length == 0) // only add if not added
{
$("#email").parent().after("<div class='validation' style='color:red;margin-bottom: 20px;'>Please enter email address</div>");
}
e.preventDefault(); // prevent form from POST to server
$('#email').focus();
focusSet = true;
} else {
$("#email").parent().next(".validation").remove(); // remove it
}
if (!$('#password').val()) {
if ($("#password").parent().next(".validation").length == 0) // only add if not added
{
$("#password").parent().after("<div class='validation' style='color:red;margin-bottom: 20px;'>Please enter password</div>");
}
e.preventDefault(); // prevent form from POST to server
if (!focusSet) {
$("#password").focus();
}
} else {
$("#password").parent().next(".validation").remove(); // remove it
}
});
The CSS:
.validation
{
color: red;
margin-bottom: 20px;
}
The for loop is definitely more pythonic, as it uses Python's higher level built in functionality to convey what you're doing both more clearly and concisely. The overhead of range vs xrange, and assigning an unused i
variable, stem from the absence of a statement like Verilog's repeat
statement. The main reason to stick to the for range solution is that other ways are more complex. For instance:
from itertools import repeat
for unused in repeat(None, 10):
del unused # redundant and inefficient, the name is clear enough
print "This is run 10 times"
Using repeat instead of range here is less clear because it's not as well known a function, and more complex because you need to import it. The main style guides if you need a reference are PEP 20 - The Zen of Python and PEP 8 - Style Guide for Python Code.
We also note that the for range version is an explicit example used in both the language reference and tutorial, although in that case the value is used. It does mean the form is bound to be more familiar than the while expansion of a C-style for loop.

From Content assist for static imports
To get content assist proposals for static members configure your list of favorite static members on the Opens the Favorites preference page
Java > Editor > Content Assist > Favorites
preference page.
For example, if you have addedjava.util.Arrays.*
ororg.junit.Assert.*
to this list, then all static methods of this type matching the completion prefix will be added to the proposals list.

Yes, just delete the branch by running git push origin :branchname
. To fix a new issue later, branch off from master again.
Please have a look at this matplotlib example page. There it is shown how to get the following plot with four individual colorbars for each subplot:

Saving and Retriving data to - from Firebase ( deprecated ver 2.4.2 )
Firebase fb_parent = new Firebase("YOUR-FIREBASE-URL/");
Firebase fb_to_read = fb_parent.child("students/names");
Firebase fb_put_child = fb_to_read.push(); // REMEMBER THIS FOR PUSH METHOD
//INSERT DATA TO STUDENT - NAMES I Use Push Method
fb_put_child.setValue("Zacharia"); //OR fb_put_child.setValue(YOUR MODEL)
fb_put_child.setValue("Joseph"); //OR fb_put_child.setValue(YOUR MODEL)
fb_put_child.setValue("bla blaaa"); //OR fb_put_child.setValue(YOUR MODEL)
//GET DATA FROM FIREBASE INTO ARRAYLIST
fb_to_read.addValuesEventListener....{
public void onDataChange(DataSnapshot result){
List<String> lst = new ArrayList<String>(); // Result will be holded Here
for(DataSnapshot dsp : result.getChildren()){
lst.add(String.valueOf(dsp.getKey())); //add result into array list
}
//NOW YOU HAVE ARRAYLIST WHICH HOLD RESULTS
for(String data:lst){
Toast.make(context,data,Toast.LONG_LENGTH).show;
}
}
}
We can use $set
operator to update the nested array inside object filed update the value
db.getCollection('geolocations').update(
{
"_id" : ObjectId("5bd3013ac714ea4959f80115"),
"geolocation.country" : "United States of America"
},
{ $set:
{
"geolocation.$.country" : "USA"
}
},
false,
true
);
Vim requires the cursor to be in the current screen at all times, however, you could bookmark the current position scroll around and then return to where you were.
mg # This book marks the current position as g (this can be any letter)
<scroll around>
`g # return to g
If spring-security
jars are added in classpath and also if it is spring-boot
application all http endpoints will be secured by default security configuration class SecurityAutoConfiguration
This causes a browser pop-up to ask for credentials.
The password changes for each application restarts and can be found in console.
Using default security password: 78fa095d-3f4c-48b1-ad50-e24c31d5cf35
To add your own layer of application security in front of the defaults,
@EnableWebSecurity
public class SecurityConfig {
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("user").password("password").roles("USER");
}
}
or if you just want to change password you could override default with,
application.xml
security.user.password=new_password
or
application.properties
spring.security.user.name=<>
spring.security.user.password=<>
Switch the order of the functions or do a forward declaration of the writefiles function and it will work I think.
The method getContentAsByteArray() of the Spring class ContentCachingRequestWrapper reads the body multiple times, but the methods getInputStream() and getReader() of the same class do not read the body multiple times:
"This class caches the request body by consuming the InputStream. If we read the InputStream in one of the filters, then other subsequent filters in the filter chain can't read it anymore. Because of this limitation, this class is not suitable in all situations."
In my case more general solution that solved this problem was to add following three classes to my Spring boot project (and the required dependencies to the pom file):
CachedBodyHttpServletRequest.java:
public class CachedBodyHttpServletRequest extends HttpServletRequestWrapper {
private byte[] cachedBody;
public CachedBodyHttpServletRequest(HttpServletRequest request) throws IOException {
super(request);
InputStream requestInputStream = request.getInputStream();
this.cachedBody = StreamUtils.copyToByteArray(requestInputStream);
}
@Override
public ServletInputStream getInputStream() throws IOException {
return new CachedBodyServletInputStream(this.cachedBody);
}
@Override
public BufferedReader getReader() throws IOException {
// Create a reader from cachedContent
// and return it
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(this.cachedBody);
return new BufferedReader(new InputStreamReader(byteArrayInputStream));
}
}
CachedBodyServletInputStream.java:
public class CachedBodyServletInputStream extends ServletInputStream {
private InputStream cachedBodyInputStream;
public CachedBodyServletInputStream(byte[] cachedBody) {
this.cachedBodyInputStream = new ByteArrayInputStream(cachedBody);
}
@Override
public boolean isFinished() {
try {
return cachedBodyInputStream.available() == 0;
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return false;
}
@Override
public boolean isReady() {
return true;
}
@Override
public void setReadListener(ReadListener readListener) {
throw new UnsupportedOperationException();
}
@Override
public int read() throws IOException {
return cachedBodyInputStream.read();
}
}
ContentCachingFilter.java:
@Order(value = Ordered.HIGHEST_PRECEDENCE)
@Component
@WebFilter(filterName = "ContentCachingFilter", urlPatterns = "/*")
public class ContentCachingFilter extends OncePerRequestFilter {
@Override
protected void doFilterInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, FilterChain filterChain) throws ServletException, IOException {
System.out.println("IN ContentCachingFilter ");
CachedBodyHttpServletRequest cachedBodyHttpServletRequest = new CachedBodyHttpServletRequest(httpServletRequest);
filterChain.doFilter(cachedBodyHttpServletRequest, httpServletResponse);
}
}
I also added the following dependencies to pom:

If you're just doing some quick and dirty temporary work, you can also skip typing out an explicit CREATE TABLE statement and just make the temp table with a SELECT...INTO and include an Identity field in the select list.
select IDENTITY(int, 1, 1) as ROW_ID,
Name
into #tmp
from (select 'Bob' as Name union all
select 'Susan' as Name union all
select 'Alice' as Name) some_data
select *
from #tmp
If you need to do a complex regexp replacement including \r\n, you can workaround the limitation by a three-step approach:
\r\n
by a tag, let's say #GO#
? Check 'Extended', replace \r\n
by #GO#
ICON="*"
from an html bookmarks ? Check regexp, replace ICON=.[^"]+.> by >
#GO#
by \r\n
I have change all columns width in my case as
worksheet.Columns[1].ColumnWidth = 7;
worksheet.Columns[2].ColumnWidth = 15;
worksheet.Columns[3].ColumnWidth = 15;
worksheet.Columns[4].ColumnWidth = 15;
worksheet.Columns[5].ColumnWidth = 18;
worksheet.Columns[6].ColumnWidth = 8;
worksheet.Columns[7].ColumnWidth = 13;
worksheet.Columns[8].ColumnWidth = 17;
worksheet.Columns[9].ColumnWidth = 17;
Note: Columns in worksheet start with 1 not from 0 as in Arrary.
I suppose because you didn't specify plugin version so it triggers the download of associated metadata in order to get the last one.
Otherwise did you try to force local repo usage using -o ?
# reorder by column name
data <- data[c("A", "B", "C")]
#reorder by column index
data <- data[c(1,3,2)]
You can also customize the card theme globally with ThemeData.cardTheme
:
MaterialApp(
title: 'savvy',
theme: ThemeData(
cardTheme: CardTheme(
shape: RoundedRectangleBorder(
borderRadius: const BorderRadius.all(
Radius.circular(8.0),
),
),
),
// ...
This is due to spring-config.xml is not in classpath.
Add complete path of spring-config.xml to your classpath.
Also write command you execute to run your project. You can check classpath in command.
Another approach which seemed to work for me at least in Linux environment is to run your Node.js application like this:
env TZ='Europe/Amsterdam' node server.js
This should at least ensure that the timezone is correctly set already from the beginning.
You can use:
MYSTRING="abc123"
MYLENGTH=$(printf "%s" "$MYSTRING" | wc -c)
wc -c
or wc --bytes
for byte counts = Unicode characters are counted with 2, 3 or more bytes.wc -m
or wc --chars
for character counts = Unicode characters are counted single until they use more bytes.Try this: Directory.Exists(TheFolderName)
and Directory.CreateDirectory(TheFolderName)
(You may need: Imports System.IO
)
untested.cmd
;@echo off
;Findstr -rbv ; %0 | powershell -c -
;goto:sCode
set-location "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings"
set-location ZoneMap\Domains
new-item TESTSERVERNAME
set-location TESTSERVERNAME
new-itemproperty . -Name http -Value 2 -Type DWORD
;:sCode
;echo done
;pause & goto :eof
<script>
$(document).ready(function(){
$('#colorselector').on('change', function() {
if ( this.value == 'red')
{
$("#divid").show();
}
else
{
$("#divid").hide();
}
});
});
</script>
Do like this for every value
You can use button classes btn-link
and btn-xs
with type submit
, which will make a small invisible button with an icon inside of it. Example:
<button class="btn btn-link btn-xs" type="submit" name="action" value="delete">
<i class="fa fa-times text-danger"></i>
</button>
Linux kernel 5.0 source comments
I knew that x86 specifics are under arch/x86
, and that syscall stuff goes under arch/x86/entry
. So a quick git grep rdi
in that directory leads me to arch/x86/entry/entry_64.S:
/*
* 64-bit SYSCALL instruction entry. Up to 6 arguments in registers.
*
* This is the only entry point used for 64-bit system calls. The
* hardware interface is reasonably well designed and the register to
* argument mapping Linux uses fits well with the registers that are
* available when SYSCALL is used.
*
* SYSCALL instructions can be found inlined in libc implementations as
* well as some other programs and libraries. There are also a handful
* of SYSCALL instructions in the vDSO used, for example, as a
* clock_gettimeofday fallback.
*
* 64-bit SYSCALL saves rip to rcx, clears rflags.RF, then saves rflags to r11,
* then loads new ss, cs, and rip from previously programmed MSRs.
* rflags gets masked by a value from another MSR (so CLD and CLAC
* are not needed). SYSCALL does not save anything on the stack
* and does not change rsp.
*
* Registers on entry:
* rax system call number
* rcx return address
* r11 saved rflags (note: r11 is callee-clobbered register in C ABI)
* rdi arg0
* rsi arg1
* rdx arg2
* r10 arg3 (needs to be moved to rcx to conform to C ABI)
* r8 arg4
* r9 arg5
* (note: r12-r15, rbp, rbx are callee-preserved in C ABI)
*
* Only called from user space.
*
* When user can change pt_regs->foo always force IRET. That is because
* it deals with uncanonical addresses better. SYSRET has trouble
* with them due to bugs in both AMD and Intel CPUs.
*/
and for 32-bit at arch/x86/entry/entry_32.S:
/*
* 32-bit SYSENTER entry.
*
* 32-bit system calls through the vDSO's __kernel_vsyscall enter here
* if X86_FEATURE_SEP is available. This is the preferred system call
* entry on 32-bit systems.
*
* The SYSENTER instruction, in principle, should *only* occur in the
* vDSO. In practice, a small number of Android devices were shipped
* with a copy of Bionic that inlined a SYSENTER instruction. This
* never happened in any of Google's Bionic versions -- it only happened
* in a narrow range of Intel-provided versions.
*
* SYSENTER loads SS, ESP, CS, and EIP from previously programmed MSRs.
* IF and VM in RFLAGS are cleared (IOW: interrupts are off).
* SYSENTER does not save anything on the stack,
* and does not save old EIP (!!!), ESP, or EFLAGS.
*
* To avoid losing track of EFLAGS.VM (and thus potentially corrupting
* user and/or vm86 state), we explicitly disable the SYSENTER
* instruction in vm86 mode by reprogramming the MSRs.
*
* Arguments:
* eax system call number
* ebx arg1
* ecx arg2
* edx arg3
* esi arg4
* edi arg5
* ebp user stack
* 0(%ebp) arg6

glibc 2.29 Linux x86_64 system call implementation
Now let's cheat by looking at a major libc implementations and see what they are doing.
What could be better than looking into glibc that I'm using right now as I write this answer? :-)
glibc 2.29 defines x86_64 syscalls at sysdeps/unix/sysv/linux/x86_64/sysdep.h
and that contains some interesting code, e.g.:
/* The Linux/x86-64 kernel expects the system call parameters in
registers according to the following table:
syscall number rax
arg 1 rdi
arg 2 rsi
arg 3 rdx
arg 4 r10
arg 5 r8
arg 6 r9
The Linux kernel uses and destroys internally these registers:
return address from
syscall rcx
eflags from syscall r11
Normal function call, including calls to the system call stub
functions in the libc, get the first six parameters passed in
registers and the seventh parameter and later on the stack. The
register use is as follows:
system call number in the DO_CALL macro
arg 1 rdi
arg 2 rsi
arg 3 rdx
arg 4 rcx
arg 5 r8
arg 6 r9
We have to take care that the stack is aligned to 16 bytes. When
called the stack is not aligned since the return address has just
been pushed.
Syscalls of more than 6 arguments are not supported. */
and:
/* Registers clobbered by syscall. */
# define REGISTERS_CLOBBERED_BY_SYSCALL "cc", "r11", "cx"
#undef internal_syscall6
#define internal_syscall6(number, err, arg1, arg2, arg3, arg4, arg5, arg6) \
({ \
unsigned long int resultvar; \
TYPEFY (arg6, __arg6) = ARGIFY (arg6); \
TYPEFY (arg5, __arg5) = ARGIFY (arg5); \
TYPEFY (arg4, __arg4) = ARGIFY (arg4); \
TYPEFY (arg3, __arg3) = ARGIFY (arg3); \
TYPEFY (arg2, __arg2) = ARGIFY (arg2); \
TYPEFY (arg1, __arg1) = ARGIFY (arg1); \
register TYPEFY (arg6, _a6) asm ("r9") = __arg6; \
register TYPEFY (arg5, _a5) asm ("r8") = __arg5; \
register TYPEFY (arg4, _a4) asm ("r10") = __arg4; \
register TYPEFY (arg3, _a3) asm ("rdx") = __arg3; \
register TYPEFY (arg2, _a2) asm ("rsi") = __arg2; \
register TYPEFY (arg1, _a1) asm ("rdi") = __arg1; \
asm volatile ( \
"syscall\n\t" \
: "=a" (resultvar) \
: "0" (number), "r" (_a1), "r" (_a2), "r" (_a3), "r" (_a4), \
"r" (_a5), "r" (_a6) \
: "memory", REGISTERS_CLOBBERED_BY_SYSCALL); \
(long int) resultvar; \
})
which I feel are pretty self explanatory. Note how this seems to have been designed to exactly match the calling convention of regular System V AMD64 ABI functions: https://en.wikipedia.org/wiki/X86_calling_conventions#List_of_x86_calling_conventions
Quick reminder of the clobbers:
cc
means flag registers. But Peter Cordes comments that this is unnecessary here.memory
means that a pointer may be passed in assembly and used to access memoryFor an explicit minimal runnable example from scratch see this answer: How to invoke a system call via syscall or sysenter in inline assembly?

The best ans for me is to write the file / directory(to be copied) to the vagrant file directory, now any file present there is available to vagrant in path /vagrant.
That's it, no need of scp or any other methods,
similarly you can copy any file from VM to host by pasting in /vagrant directory.
Java 8 Stream API
can be used for the purpose,
ArrayList<String> list1 = new ArrayList<>();
list1.add("A");
list1.add("B");
list1.add("A");
list1.add("D");
list1.add("G");
ArrayList<String> list2 = new ArrayList<>();
list2.add("B");
list2.add("D");
list2.add("E");
list2.add("G");
List<String> noDup = Stream.concat(list1.stream(), list2.stream())
.distinct()
.collect(Collectors.toList());
noDup.forEach(System.out::println);
En passant, it shouldn't be forgetten that distinct()
makes use of hashCode()
.
As far as I am aware, simply opening the file in write mode without append mode will erase the contents of the file.
ofstream file("filename.txt"); // Without append
ofstream file("filename.txt", ios::app); // with append
The first one will place the position bit at the beginning erasing all contents while the second version will place the position bit at the end-of-file bit and write from there.
Kotlin way
editText.setOnFocusChangeListener { _, hasFocus ->
if (!hasFocus) { }
}
I also came across this problem. Google detected my Mac as a new device and blocked it. To unblock, in a web browser log in to your Google account and go to "Account Settings".
Scroll down and you'll find "Recent activities". Click just below that on "Devices".
Your device will be listed. Okay your device. SMTP started working for me after I did this and lowered the protection as mentioned above.
Try this
typeof(IFoo).IsAssignableFrom(typeof(BarClass));
This will tell you whether BarClass(Derived)
implements IFoo(SomeType)
or not
You can also do it without negative look ahead. You just need to add parentheses to that part of expression which you want to extract. This construction with parentheses is named group
.
Let's write python code:
string = """OK SYS 10 LEN 20 12 43
1233a.fdads.txt,23 /data/a11134/a.txt
3232b.ddsss.txt,32 /data/d13f11/b.txt
3452d.dsasa.txt,1234 /data/c13af4/f.txt
.
"""
search_result = re.search(r"^OK.*\n((.|\s)*).", string)
if search_result:
print(search_result.group(1))
Output is:
1233a.fdads.txt,23 /data/a11134/a.txt
3232b.ddsss.txt,32 /data/d13f11/b.txt
3452d.dsasa.txt,1234 /data/c13af4/f.txt
^OK.*\n
will find first line with OK statement, but we don't want to extract it so leave it without parentheses. Next is part which we want to capture: ((.|\s)*)
, so put it inside parentheses. And in the end of regexp we look for a dot .
, but we also don't want to capture it.
P.S: I find this answer is super helpful to understand power of groups. https://stackoverflow.com/a/3513858/4333811
Don't set the style object itself, set the background color property of the style object that is a property of the element.
And yes, even though you said no, jquery and tablesorter with its zebra stripe plugin can do this all for you in 3 lines of code.
And just setting the class attribute would be better since then you have non-hard-coded control over the styling which is more organized
1 - remove the margin from your BODY CSS.
2 - wrap all of your html in a wrapper <div id="wrapper"> ... all your body content </div>
3 - Define the CSS for the wrapper:
This will hold everything together, centered on the page.
#wrapper {
margin-left:auto;
margin-right:auto;
width:960px;
}
I use a utility that I wrote in C called autotab
. It analyzes the first few thousand lines of a file which you load and determines values for the Vim parameters shiftwidth
, tabstop
and expandtab
.
This is compiled using, for instance, gcc -O autotab.c -o autotab
. Instructions for integrating with Vim are in the comment header at the top.
Autotab is fairly clever, but can get confused from time to time, in particular by that have been inconsistently maintained using different indentation styles.
If a file evidently uses tabs, or a combination of tabs and spaces, for indentation, Autotab will figure out what tab size is being used by considering factors like alignment of internal elements across successive lines, such as comments.
It works for a variety of programming languages, and is forgiving for "out of band" elements which do not obey indentation increments, such as C preprocessing directives, C statement labels, not to mention the obvious blank lines.
This is what I ended up using. Temporarily sets target to _blank, then sets it back.
OnClientClick="var originalTarget = document.forms[0].target; document.forms[0].target = '_blank'; setTimeout(function () { document.forms[0].target = originalTarget; }, 3000);"
Use localhost
instead of 127.0.0.1
(in your .env file), then run command:
php artisan config:cache
If you have only these regular shapes, there is a simple procedure as follows :
approxPolyDP
function.Below is my example in Python:
import numpy as np
import cv2
img = cv2.imread('shapes.png')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
ret,thresh = cv2.threshold(gray,127,255,1)
contours,h = cv2.findContours(thresh,1,2)
for cnt in contours:
approx = cv2.approxPolyDP(cnt,0.01*cv2.arcLength(cnt,True),True)
print len(approx)
if len(approx)==5:
print "pentagon"
cv2.drawContours(img,[cnt],0,255,-1)
elif len(approx)==3:
print "triangle"
cv2.drawContours(img,[cnt],0,(0,255,0),-1)
elif len(approx)==4:
print "square"
cv2.drawContours(img,[cnt],0,(0,0,255),-1)
elif len(approx) == 9:
print "half-circle"
cv2.drawContours(img,[cnt],0,(255,255,0),-1)
elif len(approx) > 15:
print "circle"
cv2.drawContours(img,[cnt],0,(0,255,255),-1)
cv2.imshow('img',img)
cv2.waitKey(0)
cv2.destroyAllWindows()
Below is the output:
Remember, it works only for regular shapes.
Alternatively to find circles, you can use houghcircles

Just incase u didnt understand
e.g is that lets say i have a JSON STRING ..NOT YET A JSON OBJECT OR ARRAY.
so if in javascript u parse the string as
var body={
"id": 1,
"deleted_at": null,
"open_order": {
"id": 16,
"status": "open"}
var jsonBody = JSON.parse(body.open_order); //HERE THE ERROR NOW APPEARS BECAUSE THE STRING IS NOT A JSON OBJECT YET!!!!
//TODO SO
var jsonBody=JSON.parse(body)//PASS THE BODY FIRST THEN LATER USE THE jsonBody to get the open_order
var OpenOrder=jsonBody.open_order;
Great answers above
I was trying 'DESC table_name' but then this worked for me in psql:
select *
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME='table_name';
I open files "directly" from WinSCP which opens the files in Notepad++ I had a php files on my linux server which always opened in Mac format no matter what I did :-(
If I downloaded the file and then opened it from local (windows) it was open as Dos/Windows....hmmm
The solution was to EOL-convert the local file to "UNIX/OSX Format", save it and then upload it.
Now when I open the file directly from the server it's open as "Dos/Windows" :-)
The first snippet is correct, but you need to call it after onMeasure()
gets executed. Otherwise the size is not yet measured for the view.
function b64_to_utf8( str ) {_x000D_
return decodeURIComponent(escape(window.atob( str )));_x000D_
}
_x000D_
SELECT * FROM A AS b INNER JOIN A AS c ON b.a = c.a
WHERE b.a = 'some column value'
Best solution is to put a div into table cell with zero width. Tbody table cells will inherit their widths from widths defined the thead. Position:relative and negative margin should do the trick!
Here is a screenshot: https://flic.kr/p/nvRs4j
<body>
<!-- SOME CSS -->
<style>
.cropped-table-cells,
.cropped-table-cells tr td {
margin:0px;
padding:0px;
border-collapse:collapse;
}
.cropped-table-cells tr td {
border:1px solid lightgray;
padding:3px 5px 3px 5px;
}
.no-overflow {
display:inline-block;
white-space:nowrap;
position:relative; /* must be relative */
width:100%; /* fit to table cell width */
margin-right:-1000px; /* technically this is a less than zero width object */
overflow:hidden;
}
</style>
<!-- CROPPED TABLE BODIES -->
<table class="cropped-table-cells">
<thead>
<tr>
<td style="width:100px;" width="100"><span>ORDER<span></td>
<td style="width:100px;" width="100"><span>NAME<span></td>
<td style="width:200px;" width="200"><span>EMAIL</span></td>
</tr>
</thead>
<tbody>
<tr>
<td><span class="no-overflow">123</span></td>
<td><span class="no-overflow">Lorem ipsum dolor sit amet, consectetur adipisicing elit</span></td>
<td><span class="no-overflow">sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</span></td>
</tbody>
</table>
</body>
This work fine:
Add the dependency:
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-jdk8</artifactId>
</dependency>
Add the annotation:
@JsonFormat(pattern="yyyy-MM-dd")
Now, you must get the correct format.
To use object mapper, you need register the JavaTime
ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JavaTimeModule());
