This is generic code for configuration collection :
public class GenericConfigurationElementCollection<T> : ConfigurationElementCollection, IEnumerable<T> where T : ConfigurationElement, new()
{
List<T> _elements = new List<T>();
protected override ConfigurationElement CreateNewElement()
{
T newElement = new T();
_elements.Add(newElement);
return newElement;
}
protected override object GetElementKey(ConfigurationElement element)
{
return _elements.Find(e => e.Equals(element));
}
public new IEnumerator<T> GetEnumerator()
{
return _elements.GetEnumerator();
}
}
After you have GenericConfigurationElementCollection
,
you can simple use it in the config section (this is an example from my Dispatcher):
public class DispatcherConfigurationSection: ConfigurationSection
{
[ConfigurationProperty("maxRetry", IsRequired = false, DefaultValue = 5)]
public int MaxRetry
{
get
{
return (int)this["maxRetry"];
}
set
{
this["maxRetry"] = value;
}
}
[ConfigurationProperty("eventsDispatches", IsRequired = true)]
[ConfigurationCollection(typeof(EventsDispatchConfigurationElement), AddItemName = "add", ClearItemsName = "clear", RemoveItemName = "remove")]
public GenericConfigurationElementCollection<EventsDispatchConfigurationElement> EventsDispatches
{
get { return (GenericConfigurationElementCollection<EventsDispatchConfigurationElement>)this["eventsDispatches"]; }
}
}
The Config Element is config Here:
public class EventsDispatchConfigurationElement : ConfigurationElement
{
[ConfigurationProperty("name", IsRequired = true)]
public string Name
{
get
{
return (string) this["name"];
}
set
{
this["name"] = value;
}
}
}
The config file would look like this:
<?xml version="1.0" encoding="utf-8" ?>
<dispatcherConfigurationSection>
<eventsDispatches>
<add name="Log" ></add>
<add name="Notification" ></add>
<add name="tester" ></add>
</eventsDispatches>
</dispatcherConfigurationSection>
Hope it help !

Another way to paste is via <C-r>
in insert mode and dropping the contents of the register (here the global register). See: :h i_ctrl-r
and h i_CTRL-R_CTRL-O
.
From the vim help documentation:
Insert the contents of a register literally and don't auto-indent. Does the same as pasting with the mouse. Does not replace characters! The '.' register (last inserted text) is still inserted as typed.{not in Vi}
So to paste contents into vim without auto indent, use <C-r><C-o>*
in most unix systems.
You can add a mapping in the your vimrc inoremap <C-r> <C-r><C-o>
so you can paste the contents of the *
register normally without the auto indent by using <C-r>*
.
Note: this only works if vim is compiled with clipboard
.
Maybe the current user is not root,try sudo mysql -uroot -p ,I successed just now.
you can configure the coverage exclusion in the sonar properties, outside of the configuration of the jacoco plugin:
...
<properties>
....
<sonar.exclusions>
**/generated/**/*,
**/model/**/*
</sonar.exclusions>
<sonar.test.exclusions>
src/test/**/*
</sonar.test.exclusions>
....
<sonar.java.coveragePlugin>jacoco</sonar.java.coveragePlugin>
<sonar.jacoco.reportPath>${project.basedir}/../target/jacoco.exec</sonar.jacoco.reportPath>
<sonar.coverage.exclusions>
**/generated/**/*,
**/model/**/*
</sonar.coverage.exclusions>
<jacoco.version>0.7.5.201505241946</jacoco.version>
....
</properties>
....
and remember to remove the exclusion settings from the plugin
src/main/resources
is the "standard placement" for this.
Update: The above answers the question, but its not the best solution. Check out the other answers and the comments on this ... you would probably not shipping your own logging properties with the jar but instead leave it to the client (for example app-server, stage environment, etc) to configure the desired logging. Thus, putting it in src/test/resources
is my preferred solution.
Note: Speaking of leaving the concrete log config to the client/user, you should consider replacing log4j
with slf4j
in your app.
Is there difference in defining Id & name in ApplicationContext xml ? No As of 3.1(spring), id is also defined as an xsd:string type. It means whatever characters allowed in defining name are also allowed in Id. This was not possible prior to Spring 3.1.
Why to use name when it is same as Id ? It is useful for some situations, such as allowing each component in an application to refer to a common dependency by using a bean name that is specific to that component itself.
For example, the configuration metadata for subsystem A may refer to a DataSource via the name subsystemA-dataSource. The configuration metadata for subsystem B may refer to a DataSource via the name subsystemB-dataSource. When composing the main application that uses both these subsystems the main application refers to the DataSource via the name myApp-dataSource. To have all three names refer to the same object you add to the MyApp configuration metadata the following
<bean id="myApp-dataSource" name="subsystemA-dataSource,subsystemB-dataSource" ..../>
Alternatively, You can have separate xml configuration files for each sub-system and then you can make use of
alias to define your own names.
<alias name="subsystemA-dataSource" alias="subsystemB-dataSource"/>
<alias name="subsystemA-dataSource" alias="myApp-dataSource" />
I just got the solution to this problem from a friend. he said: Add ob_start(); under your session code. You can add exit(); under the header. I tried it and it worked. Hope this helps

the easiest way would to use the eclipse IDE itself. Go to the menu and set build path. Make it point to the JAVA JDK and JRE file path in your directory. afterwards you can check the build path where compiled files are going to be set. in the bin folder by default though. The best thing would be to allow eclipse to handle itself the build path and only to edit it similar to the solution that is given above
I was experiencing this issue and it was driving me nuts; I ultimately found the following lying in my POM.xml, which was the cause of the problem:
<resources>

<directory>src/main/resources</directory>
<filtering>true</filtering>
<includes>
<include>**/*.properties</include>
</includes>
</resource>
</resources>
It is recommended to check default terminal shell before set JAVA_HOME environment variable, via following commands:
$ echo $SHELL
/bin/bash
If your default terminal is /bin/bash (Bash), then you should use @hygull method
If your default terminal is /bin/zsh (Z Shell), then you should set these environment variable in ~/.zshenv file with following contents:
export JAVA_HOME="$(/usr/libexec/java_home)"
Similarly, any other terminal type not mentioned above, you should set environment variable in its respective terminal env file.
This method tested working in macOS Mojave Version 10.14.6.
In addition to Ishmaeel's answer, the method OpenMappedMachineConfiguration()
will always return a Configuration
object. So to check to see if it loaded you should check the HasFile
property where true means it came from a file.
Generally speaking, command line options will override environment variables which will override user defaults which will override system defaults.
In startup.cs, add the constructor
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
Access the settings using Configuration["SecureCookies"]
Fundamentally you hadn't declare location which is what nginx uses to bind URL with resources.
server {
listen 80;
server_name localhost;
access_log logs/localhost.access.log main;
location / {
root /var/www/board/public;
index index.html index.htm index.php;
}
}
I don't know why this answer hasn't already been given:
Different callers of the same library will, in general, use different configurations. This implies that the configuration must reside in the executable application, and not in the class library.
You may create an app.config within the class library project. It will contain default configurations for items you create within the library. For instance, it will contain connection strings if you create an Entity Framework model within the class library.
However, these settings will not be used by the executable application calling the library. Instead, these settings may be copied from the library.dll.config file into the app.config or web.config of the caller, so that they may be changed to be specific to the caller, and to the environment into which the caller is deployed.
This is how it has been with .NET since Day 1.

I know this question is answered, but I would like to share the Kotlin code I did to retrieve the Spring Context.
I am not a specialist, so I am open to critics, reviews and advices:

/**
*
* Singleton object to create (only if necessary), return and reuse a Spring Application Context.
*
* When you instantiates a class by yourself, spring context does not autowire its properties, but you can wire by yourself.
* This class helps to find a context or create a new one, so you can wire properties inside objects that are not
* created by Spring (e.g.: Servlets, usually created by the web server).
*
* Sometimes a SpringContext is created inside jUnit tests, or in the application server, or just manually. Independent
* where it was created, I recommend you to configure your spring configuration to scan this SpringUtils package, so the 'springAppContext'
* property will be used and autowired at the SpringUtils object the start of your spring context, and you will have just one instance of spring context public available.
*
*Ps: Even if your spring configuration doesn't include the SpringUtils @Component, it will works tto, but it will create a second Spring Context o your application.

Now, a spring context is publicly available, being able to call the same method independent of the context (junit tests, beans, manually instantiated classes) like on this Java Servlet:
@WebServlet(name = "MyWebHook", value = "/WebHook")
public class MyWebServlet extends HttpServlet {
private MyBean byBean
= SpringUtils.INSTANCE.ctx(this, true).getBean(MyBean.class);
public MyWebServlet() {
}
}
There are two types of contexts we are dealing with:
1: root context (parent context. Typically include all jdbc(ORM, Hibernate) initialisation and other spring security related configuration)
2: individual servlet context (child context.Typically Dispatcher Servlet Context and initialise all beans related to spring-mvc (controllers , URL Mapping etc)).

I had the same problem, in my case handler was in two places:
<system.web>
...
<httpHandlers>
<add verb="*" path="*.ashx" type="ApplicArt.Extranet2.Controller.FrontController, ApplicArt.Extranet2.Web.UI" />
</httpHandlers>
</system.web>
<system.webServer>
<handlers>
...
<add name="FrontController" verb="*" path="*.ashx" type="ApplicArt.Extranet2.Controller.FrontController, ApplicArt.Extranet2.Web.UI"/>
</handlers>
</system.webServer>
And when I removed my handler from [system.webServer] my problem disappeared.
If you are on Linux, then start the 'mysqld' with strace
, for eg strace ./mysqld
.
Among all the other system calls, you will find something like:
stat64("/etc/my.cnf", 0xbfa3d7fc) = -1 ENOENT (No such file or directory)
stat64("/etc/mysql/my.cnf", {st_mode=S_IFREG|0644, st_size=4227, ...}) = 0
open("/etc/mysql/my.cnf", O_RDONLY|O_LARGEFILE) = 3
So, as you can see..it lists the .cnf files, that it attempts to use and finally uses.
If (as I understand) you're trying to completely block inheritance in the web config of your child application, I suggest you to avoid using the tag in web.config.
Instead create a new apppool and edit the applicationHost.config file (located in %WINDIR%\System32\inetsrv\Config and %WINDIR%\SysWOW64\inetsrv\config).
You just have to find the entry for your apppool and add the attribute enableConfigurationOverride="false"
like in the following example:
<add name="MyAppPool" autoStart="true" managedRuntimeVersion="v4.0" managedPipelineMode="Integrated" enableConfigurationOverride="false">
<processModel identityType="NetworkService" />
</add>
This will avoid configuration inheritance in the applications served by MyAppPool.

From Spring docs,
Embedded servlet containers - Add a Servlet, Filter or Listener to an application
To add a Servlet, Filter, or Servlet *Listener provide a @Bean definition for it.
Eg:
@Bean
public Filter compressFilter() {
CompressingFilter compressFilter = new CompressingFilter();
return compressFilter;
}
Add this @Bean
config to your @Configuration
class and filter will be registered on startup.
Also you can add Servlets, Filters, and Listeners using classpath scanning,
@WebServlet, @WebFilter, and @WebListener annotated classes can be automatically registered with an embedded servlet container by annotating a @Configuration class with @ServletComponentScan and specifying the package(s) containing the components that you want to register. By default, @ServletComponentScan will scan from the package of the annotated class.

If you use .netcore 3.1 the simplest way use new configuration system to call CreateDefaultBuilder
method of static class Host
and configure application
public class Program
{
public static void Main(string[] args)
{
Host.CreateDefaultBuilder(args)
.ConfigureAppConfiguration((context, config) =>
{
IHostEnvironment env = context.HostingEnvironment;
config.AddEnvironmentVariables()
// copy configuration files to output directory
.AddJsonFile("appsettings.json")
// default prefix for environment variables is DOTNET_
.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
.AddCommandLine(args);
})
.ConfigureServices(services =>
{
services.AddSingleton<IHostedService, MySimpleService>();
})
.Build()
.Run();
}
}
class MySimpleService : IHostedService
{
public Task StartAsync(CancellationToken cancellationToken)
{
Console.WriteLine("StartAsync");
return Task.CompletedTask;
}
public Task StopAsync(CancellationToken cancellationToken)
{
Console.WriteLine("StopAsync");
return Task.CompletedTask;
}
}
You need set Copy to Output Directory = 'Copy if newer' for the files appsettings.json
and appsettings.{environment}.json
Also you can set environment variable {prefix}ENVIRONMENT (default prefix is DOTNET) to allow choose specific configuration parameters.

With webpack you can put env-specific config into the externals
field in webpack.config.js
externals: {
'Config': JSON.stringify(process.env.NODE_ENV === 'production' ? {
serverUrl: "https://myserver.com"
} : {
serverUrl: "http://localhost:8090"
})
}
If you want to store the configs in a separate JSON file, that's possible too, you can require that file and assign to Config
:
externals: {
'Config': JSON.stringify(process.env.NODE_ENV === 'production' ? require('./config.prod.json') : require('./config.dev.json'))
}
Then in your modules, you can use the config:
var Config = require('Config')
fetchData(Config.serverUrl + '/Enterprises/...')
For React:
import Config from 'Config';
axios.get(this.app_url, {
'headers': Config.headers
}).then(...);
Not sure if it covers your use case but it's been working pretty well for us.
To fix this problem, you must edit your php.ini (or extensions.ini) file and comment-out the extensions that are already compiled-in. For example, after editing, your ini file may look like the lines below:

The ConfigurationManager is not what you need to access your own settings.

Solution for yml file:
1.Copy yml to in same directory that jar application
2.Run command, example for xxx.yml
:
java -jar app.jar --spring.config.location=xxx.yml
It's works fine, but in startup logger is INFO:
No active profile set .........
You can tell ESLint to ignore specific files and directories by creating an .eslintignore
file in your project’s root directory:
.eslintignore
build/*.js
config/*.js
bower_components/foo/*.js
The ignore patterns behave according to the .gitignore
specification.
(Don't forget to restart your editor.)
Proxy timeouts are well, for proxies, not for FastCGI...
The directives that affect FastCGI timeouts are client_header_timeout
, client_body_timeout
and send_timeout
.
Edit: Considering what's found on nginx wiki, the send_timeout directive is responsible for setting general timeout of response (which was bit misleading). For FastCGI there's fastcgi_read_timeout
which is affecting the fastcgi process response timeout.
HTH.
I agree with the other answers that point you to app.config. However, rather than reading values directly from app.config, you should create a utility class (AppSettings is the name I use) to read them and expose them as properties. The AppSettings class can be used to aggregate settings from several stores, such as values from app.config and application version info from the assembly (AssemblyVersion and AssemblyFileVersion).
SlowCheetah and FastKoala from the VisualStudio Gallery seem to be very good tools that help out with this problem.
However, if you want to avoid addins or use the principles they implement more extensively throughout your build/integration processes then adding this to your msbuild *proj files is a shorthand fix.
Note: this is more or less a rework of the No. 2 of @oleksii's answer.
This works for .exe and .dll projects:
<Target Name="TransformOnBuild" BeforeTargets="PrepareForBuild">
<TransformXml Source="App_Config\app.Base.config" Transform="App_Config\app.$(Configuration).config" Destination="app.config" />
</Target>
This works for web projects:
<Target Name="TransformOnBuild" BeforeTargets="PrepareForBuild">
<TransformXml Source="App_Config\Web.Base.config" Transform="App_Config\Web.$(Configuration).config" Destination="Web.config" />
</Target>
Note that this step happens even before the build proper begins. The transformation of the config file happens in the project folder. So that the transformed web.config is available when you are debugging (a drawback of SlowCheetah).
Do remember that if you create the App_Config folder (or whatever you choose to call it), the various intermediate config files should have a Build Action = None, and Copy to Output Directory = Do not copy.
This combines both options into one block. The appropriate one is executed based on conditions. The TransformXml task is defined first though:
<Project>
<UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v$(VisualStudioVersion)\Web\Microsoft.Web.Publishing.Tasks.dll" />
<Target Name="TransformOnBuild" BeforeTargets="PrepareForBuild">
<TransformXml Condition="Exists('App_Config\app.Base.config')" Source="App_Config\app.Base.config" Transform="App_Config\app.$(Configuration).config" Destination="app.config" />
<TransformXml Condition="Exists('App_Config\Web.Base.config')" Source="App_Config\Web.Base.config" Transform="App_Config\Web.$(Configuration).config" Destination="Web.config" />
</Target>
Like it was saying previously - you can access any parameters by using injection container and use its parameter property.
"Symfony - Working with Container Service Definitions" is a good article about it.
I doubt this is good practice but it's working locally. I'll update this if it fails when I publish/deploy (to an IIS web service).
Step 1 - Add this assembly to the top of your class (in my case, controller class):
using Microsoft.Extensions.Configuration;
Step 2 - Add this or something like it:
var config = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json").Build();
Step 3 - Call your key's value by doing this (returns string):
config["NameOfYourKey"]

Drop root privileges after you bind to port 80 (or 443).
This allows port 80/443 to remain protected, while still preventing you from serving requests as root:
function drop_root() {
process.setgid('nobody');
process.setuid('nobody');
}
A full working example using the above function:
var process = require('process');
var http = require('http');
var server = http.createServer(function(req, res) {
res.write("Success!");
res.end();
});
server.listen(80, null, null, function() {
console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
drop_root();
console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
});

I was having a similar problem that I could not resolve for a long time on my new server. In addition to palacsint's answer, a good question to ask is: are you using Apache 2.4? In Apache 2.4 there is a different mechanism for setting the permissions that do not work when done using the above configuration, so I used the solution explained in this blog post.
Basically, what I needed to do was convert my config file from:
Alias /demo /usr/demo/html
<Directory "/usr/demo/html">
Options FollowSymLinks
AllowOverride None
Order allow,deny
allow from all
</Directory>
to:
Alias /demo /usr/demo/html
<Directory "/usr/demo/html">
Options FollowSymLinks
AllowOverride None
Require all granted
</Directory>
Note how the Order and allow lines have been replaced by Require all granted
The answers were useful. After the change, I got duplicate logging of SQL statements, one in the log4j log file and one on the standard console. I changed the persistence.xml file to say show_sql to false to get rid of logging from the standard console. Keeping format_sql true also affects the log4j log file, so I kept that true.

$host
is a variable of the Core module.
$host
This variable is equal to line Host in the header of request or name of the server processing the request if the Host header is not available.
This variable may have a different value from $http_host in such cases: 1) when the Host input header is absent or has an empty value, $host equals to the value of server_name directive; 2)when the value of Host contains port number, $host doesn't include that port number. $host's value is always lowercase since 0.8.17.
$http_host
is also a variable of the same module but you won't find it with that name because it is defined generically as $http_HEADER
(ref).
$http_HEADER
The value of the HTTP request header HEADER when converted to lowercase and with 'dashes' converted to 'underscores', e.g. $http_user_agent, $http_referer...;
Summarizing:
$http_host
equals always the HTTP_HOST
request header.$host
equals $http_host
, lowercase and without the port number (if present), except when HTTP_HOST
is absent or is an empty value. In that case, $host
equals the value of the server_name
directive of the server which processed the request.I've created file log4j.properties in resources folder next to hibernate.cfg.xml file and filled it with text below:
log4j.rootLogger=INFO, CONSOLE
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}:%L] %m%n
now I got rid of warnings and errors
Try using ESAPIs Encryption methods. Its easy to configure and you can also easily change your keys.
http://owasp-esapi-java.googlecode.com/svn/trunk_doc/latest/org/owasp/esapi/Encryptor.html
You
1)encrypt 2)decrypt 3)sign 4)unsign 5)hashing 6)time based signatures and much more with just one library.
Use below command on UNIX terminal :
java -XshowSettings
This will display all java properties and system settings.
In this look for java.io.tmpdir
value.
I had the problem occur on my system in a very strange way. In my system customers create products that sit inside a directory structure of product categories. So ProductA might sit in the folder CategoryInner inside the folder CategoryOuter. I had just added a feature where my URL would show the category nesting on the URL thusly:
http://www.somedomain.com/product/CategoryOuter/CategoryInner/ProductA.aspx
Obviously the nesting on the URL was just for SEO purposes (and to show the user what category their product was sitting in. But when I used ResolveClientUrl on some URLs that used to work, it must've been confused by the extra fake pathing. The error message was popping up in the debugger on some line that was never the problem so it took me quite some time to figure out what was going on. I wnet through and removed all of my ResolveClientUrl calls that acted on anything that didn't start with a ~ and made the rest of the paths absolute paths.
The config file is just an XML file, you can open it by:
private static XmlDocument loadConfigDocument()
{
XmlDocument doc = null;
try
{
doc = new XmlDocument();
doc.Load(getConfigFilePath());
return doc;
}
catch (System.IO.FileNotFoundException e)
{
throw new Exception("No configuration file found.", e);
}
catch (Exception ex)
{
return null;
}
}
and later retrieving values by:
// retrieve appSettings node
XmlNode node = doc.SelectSingleNode("//appSettings");
I prefer python -m json.tool
which seems to be available per default on most *nix operating systems per default.
$ echo '{"foo":1, "bar":2}' | python -m json.tool
{
"bar": 2,
"foo": 1
}
Note: Depending on your version of python, all keys might get sorted alphabetically, which can or can not be a good thing. With python 2 it was the default to sort the keys, while in python 3.5+ they are no longer sorted automatically, but you have the option to sort by key explicitly:
$ echo '{"foo":1, "bar":2}' | python3 -m json.tool --sort-keys
{
"bar": 2,
"foo": 1
}
For me the problem was that any routes other than the base route were working, adding this line fixed my problem:
index index.php;
Full thing:
server {
server_name example.dev;
root /var/www/example/public;
index index.php;
location / {
try_files $uri $uri/ /index.php?$query_string;
}
location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
RiggsFolly answered this for me elsewhere, simply:
in your apache conf folder edit file: httpd-vhost.conf:
Add this little line inside the Directory nest:
Require ip 192.168.1
Restart the server, apache or Wamp or whatever you have.
That's it, now all your HOME deivces (in ip range 192.168.1.xxx) can see your PC server. Note you only add the first 3 parts of ip number).
Any problems, exit your firewall to test.
To see your network devices ip numbers, download an "IP Scanner" software (quite a few free ones around) for PC or for android get Fing from play store.
Put the following in your .vimrc
autocmd BufRead *.py set smartindent cinwords=if,elif,else,for,while,try,except,finally,def,class
autocmd BufRead *.py set nocindent
autocmd BufWritePre *.py normal m`:%s/\s\+$//e ``
filetype plugin indent on

I personally use JetBrain's PyCharm with the IdeaVIM plugin when doing anything complex, for simple editing the additions to .vimrc
seem sufficient.
Yes, for Virtualbox provider do something like this:
Vagrant.configure("2") do |config|
# ...other options...
config.vm.provider "virtualbox" do |p|
p.name = "something-else"
end
end
You also can use graceful restart the apache server with service apache2 reload
or apachectl -k graceful
.
As the apache doc says:
The USR1 or graceful signal causes the parent process to advise the children to exit after their current request (or to exit immediately if they're not serving anything). The parent re-reads its configuration files and re-opens its log files. As each child dies off the parent replaces it with a child from the new generation of the configuration, which begins serving new requests immediately.
In order to avoid hardcoding schema in JPA Entity Java Classes we used orm.xml mapping file in Java EE application deployed in OracleApplicationServer10 (OC4J,Orion). It lays in model.jar/META-INF/ as well as persistence.xml. Mapping file orm.xml is referenced from peresistence.xml with tag
...
<persistence-unit name="MySchemaPU" transaction-type="JTA">
<provider>
<mapping-file>META-INF/orm.xml</mapping-file>
...
File orm.xml content is cited below:

You could also make it a post-build step. Setup a new configuration which is "Deploy" in addition to Debug and Release, and then have the post-build step copy over the correct web.config.
We use automated builds for all of our projects, and with those the build script updates the web.config file to point to the correct location. But that won't help you if you are doing everything from VS.
Adding my 2 cents to the 11 year old discussion try this:
alias lock="gnome-screensaver \gnome-screensaver-command --lock"
I like to use rails-settings for global configuration values that need to be changeable via web interface.
I just moved to Spring Boot 1.4 and found these properties were renamed:
spring.datasource.dbcp.test-while-idle=true
spring.datasource.dbcp.time-between-eviction-runs-millis=3600000
spring.datasource.dbcp.validation-query=SELECT 1
It's as simple as this: the JBoss docs are not 100% perfectly well-maintained. Go with what the JavaDoc says: buildSessionFactory(ServiceRegistry serviceRegistry)
.
I used tmux-powerline to fully pimp my tmux status bar. I was googling for a way to change to background of the status bar when your typing a tmux command. When I stumbled on this post I thought I should mention it for completeness.
Update: This project is in a maintenance mode and no future functionality is likely to be added. tmux-powerline, with all other powerline projects, is replaced by the new unifying powerline. However this project is still functional and can serve as a lightweight alternative for non-python users.
I use the approach with PATH variable. Path to Notepad++ is added to system's PATH variable and then core.editor is set like following:
git config --global core.editor notepad++
Also, you may add some additional parameters for Notepad++:
git config --global core.editor "notepad++.exe -multiInst"
(as I detailed in "Git core.editor
for Windows")
And here you can find some options you may use when stating Notepad++ Command Line Options.
Yeah, when ASP.NET web.config gets updated, the whole application gets restarted which means the web.config gets reloaded.
The problem here is that there ISN'T an openssl.cnf file given with the GnuWin32 openssl stuff. You have to create it. You can find out HOW to create an openssl.cnf file by going here:
http://www.flatmtn.com/article/setting-ssl-certificates-apache
Where it lays it all out for you on how to do it.
PLEASE NOTE: The openssl command given with the backslash at the end is for UNIX. For Windows : 1)Remove the backslash, and 2)Move the second line up so it is at the end of the first line. (So you get just one command.)
ALSO: It is VERY important to read through the comments. There are some changes you might want to make based upon them.
You can use SHOW
:
SHOW max_connections;
This returns the currently effective setting. Be aware that it can differ from the setting in postgresql.conf
as there are a multiple ways to set run-time parameters in PostgreSQL. To reset the "original" setting from postgresql.conf
in your current session:
RESET max_connections;
However, not applicable to this particular setting. The manual:
This parameter can only be set at server start.
To see all settings:
SHOW ALL;
There is also pg_settings
:
The view
pg_settings
provides access to run-time parameters of the server. It is essentially an alternative interface to theSHOW
andSET
commands. It also provides access to some facts about each parameter that are not directly available fromSHOW
, such as minimum and maximum values.
For your original request:
SELECT *
FROM pg_settings
WHERE name = 'max_connections';
Finally, there is current_setting()
, which can be nested in DML statements:
SELECT current_setting('max_connections');

You can easily increase your VM's RAM by modifying the memory property of config.vm.provider section in your vagrant file.
config.vm.provider "virtualbox" do |vb|
vb.memory = "4096"
end
This allocates about 4GB of RAM to your VM. You can change this according to your requirement. For example, following setting would allocate 2GB of RAM to your VM.
config.vm.provider "virtualbox" do |vb|
vb.memory = "2048"
end
Try removing the config.vm.customize ["modifyvm", :id, "--memory", 1024]
in your file, and adding the above code.
For the network configuration, try modifying the config.vm.network :hostonly, "199.188.44.20"
in your file toconfig.vm.network "private_network", ip: "199.188.44.20"

Setting tcp-keepalive to 60 (it was set to 0) in server's redis configuration helped me resolve this issue.
I got the top answer working (can't reply yet) after one small edit
This did not work for me:
FEATURE('authinfo','hash /etc/mail/auth/client-info')dnl
The first single quote for each string should be changed to a backtick (`) like this:
FEATURE(`authinfo',`hash /etc/mail/auth/client-info')dnl
After the change I run:
sudo sendmailconfig
And I'm in business :)
The other answers were not completely satisfying to me. Here's what worked for postgresql-9.1 on Xubuntu 12.04.1 LTS.
Connect to the default database with user postgres:
sudo -u postgres psql template1
Set the password for user postgres, then exit psql (Ctrl-D):
ALTER USER postgres with encrypted password 'xxxxxxx';
Edit the pg_hba.conf
file:
sudo vim /etc/postgresql/9.1/main/pg_hba.conf
and change "peer" to "md5" on the line concerning postgres:
local all postgres
peermd5
To know what version of postgresql you are running, look for the version folder under /etc/postgresql
. Also, you can use Nano or other editor instead of VIM.
Restart the database :
sudo /etc/init.d/postgresql restart
(Here you can check if it worked with psql -U postgres
).
Create a user having the same name as you (to find it, you can type whoami
):
sudo createuser -U postgres -d -e -E -l -P -r -s
<my_name>
The options tell postgresql to create a user that can login, create databases, create new roles, is a superuser, and will have an encrypted password. The really important ones are -P -E, so that you're asked to type the password that will be encrypted, and -d so that you can do a createdb
.
Beware of passwords: it will first ask you twice the new password (for the new user), repeated, and then once the postgres password (the one specified on step 2).
Again, edit the pg_hba.conf
file (see step 3 above), and change "peer" to "md5" on the line concerning "all" other users:
local all all
peermd5
Restart (like in step 4), and check that you can login without -U postgres:
psql template1
Note that if you do a mere psql
, it will fail since it will try to connect you to a default database having the same name as you (i.e. whoami
). template1 is the admin database that is here from the start.
Now createdb <dbname>
should work.
You must use Eclipse WTP (Web Tool Platform), and should use the lastest version is Luna 4.4. Link download: Eclipse IDE for Java EE Developers http://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/lunar
Menu Windows\Show view\Other, choose folder Server, click on Servers.
Right click on blank area to use context menu, choose New\Server
Press link "Download additional server adapters"
Choose "GlassFish Tools" from Oracle vendor.
Then, restart Eclipse.
Or you download GlassFish tools (Supports GlassFish 4.0 and 3.1) from: https://marketplace.eclipse.org/content/glassfish-tools and install manually.
Read more about creating a server: http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.wst.server.ui.doc.user%2Ftopics%2Ftwcrtins.html
I had this issue too.
It started after I did a little folder tidying in my project. I then tried to compile and got many duplicate class errors. (despite them not being duplicated. I think the linking was just out of wack)
Upon checking these, the errors would all disappear leaving only the "Metadata file ...debug\application.exe could not be found" error.
I solved this by looking in the build output window to find which classes were duplicated.
I would then right click the class name and "go to definition".
there will be two definitions to select from, open them both, the second definition will seem to open the same file again, however the second one will identify as the error source(red underline).
Delete all the code out of the file and save(This will not effect your actual file).
This should now compile correctly.
in this file
[workspace].metadata.plugins\org.eclipse.core.runtime.settings\org.eclipse.ui.editors.prefs
make sure the parameter
lineNumberColor=0,0,0
is NOT 255,255, 255, which is white
Some addition to previous comments: 'firstboot' won't be available until you run 'mount_root' command.
So here is a full recap of what needs to be done. All manipulations I did on Windows 8.1.
netsh interface ip set address name="Ethernet" static 192.168.1.2 255.255.255.0 192.168.1.1
Now you can enter to the router console from a browser. Also don't forget to return your PC from static to DHCP address assignment. Example: netsh interface ip set address name="Ethernet" source=dhcp
Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.
This will be a JRE and JDK package.
There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.
Assume your code is looking for the file say app.properties. Copy this file to any dir and add this dir to classpath, by creating a setenv.sh in the bin dir of tomcat.
In your setenv.sh of tomcat( if this file is not existing, create one , tomcat will load this setenv.sh file.
#!/bin/sh
CLASSPATH="$CLASSPATH:/home/user/config_my_prod/"
You should not have your properties files in ./webapps//WEB-INF/classes/app.properties
Tomcat class loader will override the with the one from WEB-INF/classes/
A good read: https://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html
Databases implement subtle differences in the SQL
they use. Things such as data types for example vary across databases (e.g. in Oracle You might put an integer value in a number field and in SQL Server use an int field). Or database specific functionality - selecting the top n rows is different depending on the database. The dialect abstracts this so you don't have to worry about it.
If you go to Windows, Preferences then select General, Editors, Text editors, you can set colors on that property page (and there's a link for setting MORE colors - General, Appearance, Colors and fonts).
That's with an Eclipse 3.3 build anyway.
in your location block you can do:
location / {
try_files $uri $uri/index.html;
}
which will tell ngingx to look for a file with the exact name given first, and if none such file is found it will try uri/index.html. So if a request for https://www.example.com/ comes it it would look for an exact file match first, and not finding that would then check for index.html
If you want to show something you're connected on 3000
var express = require('express')
var app = express()
app.get('/', function (req, res) {
res.send('Hello World!')
})
app.listen(3000, function () {
console.log('Example app listening on port 3000!')
})
I hope that will be helpful to you
The <context:annotation-config>
tag tells Spring to scan the codebase for automatically resolving dependency requirements of the classes containing @Autowired annotation.
Spring 2.5 also adds support for JSR-250 annotations such as @Resource, @PostConstruct, and @PreDestroy.Use of these annotations also requires that certain BeanPostProcessors be registered within the Spring container. As always, these can be registered as individual bean definitions, but they can also be implicitly registered by including <context:annotation-config>
tag in spring configuration.
Taken from Spring documentation of Annotation Based Configuration
Spring provides the capability of automatically detecting 'stereotyped' classes and registering corresponding BeanDefinitions with the ApplicationContext.
According to javadoc of org.springframework.stereotype:
Stereotypes are Annotations denoting the roles of types or methods in the overall architecture (at a conceptual, rather than implementation, level). Example: @Controller @Service @Repository etc. These are intended for use by tools and aspects (making an ideal target for pointcuts).
To autodetect such 'stereotype' classes, <context:component-scan>
tag is required.
The <context:component-scan>
tag also tells Spring to scan the code for injectable beans under the package (and all its subpackages) specified.
Deleting the contents of C:\Users\%USERNAME%\AppData\Roaming\pgAdmin

The sample config you provided is actually valid YAML. In fact, YAML meets all of your demands, is implemented in a large number of languages, and is extremely human friendly. I would highly recommend you use it. The PyYAML project provides a nice python module, that implements YAML.
To use the yaml module is extremely simple:
import yaml
config = yaml.safe_load(open("path/to/config.yml"))
Error in datanode.log file
$ more /usr/local/hadoop/logs/hadoop-hduser-datanode-ubuntu.log
Shows:
java.io.IOException: Incompatible clusterIDs in /usr/local/hadoop_tmp/hdfs/datanode: namenode clusterID = CID-e4c3fed0-c2ce-4d8b-8bf3-c6388689eb82; datanode clusterID = CID-2fcfefc7-c931-4cda-8f89-1a67346a9b7c
Solution: Stop your cluster and issue the below command & then start your cluster again.
sudo rm -rf /usr/local/hadoop_tmp/hdfs/datanode/*
On newer versions of Symfony2 (using a parameters.yml
instead of parameters.ini
), you can store objects or arrays instead of key-value pairs, so you can manage your globals this way:
config.yml (edited only once):
# app/config/config.yml
twig:
globals:
project: %project%
parameters.yml:
# app/config/parameters.yml
project:
name: myproject.com
version: 1.1.42
And then in a twig file, you can use {{ project.version }}
or {{ project.name }}
.
Note: I personally dislike adding things to app
, just because that's the Symfony's variable and I don't know what will be stored there in the future.
If you use Spring Boot, you can also enable a “debug” mode by starting your application with a --debug flag.
java -jar myapp.jar --debug
You can also specify debug=true in your application.properties.
When the debug mode is enabled, a selection of core loggers (embedded container, Hibernate, and Spring Boot) are configured to output more information. Enabling the debug mode does not configure your application to log all messages with DEBUG level.
Alternatively, you can enable a “trace” mode by starting your application with a --trace flag (or trace=true in your application.properties). Doing so enables trace logging for a selection of core loggers (embedded container, Hibernate schema generation, and the whole Spring portfolio).
https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-logging.html
I found some answers, but I don't know if it is the right way.This is my solution for now. Fortunatelly it didn´t broke my design mode.

C# generally uses xml-based config files rather than the *.ini-style file like you said, so there's nothing built-in to handle this. However, google returns a number of promising results.
In my case I had to change the <VirtualHost *> back to <VirtualHost *:80> (which is the default on Ubuntu). Otherwise, the port 443 wasn't using SSL and was sending plain HTML back to the browser.
You can check whether this is your case quite easily: just connect to your server http://www.example.com:443. If you see plain HTML, your Apache is not using SSL on port 443 at all, most probably due to a VirtualHost misconfiguration.
Cheers!
I tested below code with SQL Server 2008 R2 Express and I believe we should have solution for all 6 steps you outlined. Let's take on them one-by-one:
We can enable TCP/IP protocol with WMI:
set wmiComputer = GetObject( _
"winmgmts:" _
& "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProtocols = wmiComputer.ExecQuery( _
"select * from ServerNetworkProtocol " _
& "where InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'")
if tcpProtocols.Count = 1 then
' set tcpProtocol = tcpProtocols(0)

I believe your solution will work, just make sure you specify the right port. I suggest we pick a different port than 1433 and make it a static port SQL Server Express will be listening on. I will be using 3456 in this post, but please pick a different number in the real implementation (I feel that we will see a lot of applications using 3456 soon :-)
We can use WMI again. Since we are using static port 3456, we just need to update two properties in IPAll section: disable dynamic ports and set the listening port to 3456
:
set wmiComputer = GetObject( _
"winmgmts:" _
& "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProperties = wmiComputer.ExecQuery( _
"select * from ServerNetworkProtocolProperty " _
& "where InstanceName='SQLEXPRESS' and " _
& "ProtocolName='Tcp' and IPAddressName='IPAll'")
for each tcpProperty in tcpProperties
dim setValueResult, requestedValue
if tcpProperty.PropertyName = "TcpPort" then
requestedValue = "3456"
elseif tcpProperty.PropertyName ="TcpDynamicPorts" then
requestedValue = ""
end if
setValueResult = tcpProperty.SetStringValue(requestedValue)
if setValueResult = 0 then
Wscript.Echo "" & tcpProperty.PropertyName & " set."
else
Wscript.Echo "" & tcpProperty.PropertyName & " failed!"
end if
next
Note that I didn't have to enable any of the individual addresses to make it work, but if it is required in your case, you should be able to extend this script easily to do so.
Just a reminder that when working with WMI, WBEMTest.exe is your best friend!
I wish we could use WMI again, but unfortunately this setting is not exposed through WMI. There are two other options:
Use LoginMode
property of Microsoft.SqlServer.Management.Smo.Server
class, as described here.
Use LoginMode value in SQL Server registry, as described in this post. Note that by default the SQL Server Express instance is named SQLEXPRESS
, so for my SQL Server 2008 R2 Express instance the right registry key was
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQLServer
.
You got this one covered.
Since we are using a static port assigned to our SQL Server Express instance, there's no need to use instance name in the server address anymore.
SQLCMD -U sa -P newPassword -S 192.168.0.120,3456
Please let me know if this works for you (fingers crossed!).
Its faster with MUTT command
echo "Body Of the Email" | mutt -a "File_Attachment.csv" -s "Daily Report for $(date)" -c [email protected] [email protected] -y
If you fill the DropdownList through client side script then clear the list before submit the form back to server; then ASP.NET will not complain and the security will be still on.
And to get the data selected from the DDL, you can attach an "OnChange" event to the DDL to collect the value in a hidden Input or in a textbox with Style="display: none;"
It seems like it exists a bug in jQuery reported here : http://bugs.jquery.com/ticket/13183 that breaks the Fancybox script.
Also check https://github.com/fancyapps/fancyBox/issues/485 for further reference.
As a workaround, rollback to jQuery v1.8.3 while either the jQuery bug is fixed or Fancybox is patched.
UPDATE (Jan 16, 2013): Fancybox v2.1.4 has been released and now it works fine with jQuery v1.9.0.
For fancybox v1.3.4- you still need to rollback to jQuery v1.8.3 or apply the migration script as pointed out by @Manu's answer.
UPDATE (Jan 17, 2013): Workaround for users of Fancybox v1.3.4 :
Patch the fancybox js file to make it work with jQuery v1.9.0 as follow :
Find around the line 29 where it says :
isIE6 = $.browser.msie && $.browser.version < 7 && !window.XMLHttpRequest,
and replace it by (EDITED March 19, 2013: more accurate filter):
isIE6 = navigator.userAgent.match(/msie [6]/i) && !window.XMLHttpRequest,
UPDATE (March 19, 2013): Also replace $.browser.msie
by navigator.userAgent.match(/msie [6]/i)
around line 615 (and/or replace all $.browser.msie
instances, if any), thanks joofow
... that's it!
Or download the already patched version from HERE (UPDATED March 19, 2013 ... thanks fairylee for pointing out the extra closing bracket)
NOTE: this is an unofficial patch and is unsupported by Fancybox's author, however it works as is. You may use it at your own risk ;)
Optionally, you may rather rollback to jQuery v1.8.3 or apply the migration script as pointed out by @Manu's answer.
I just want to point out that in the case that you are
Then you can just use cp foo [destination]
instead of the mentioned git-archive master foo | -x -C [destination]
.
What's your definition of a month? Technically a month can be 28,29,30 or 31 days depending on the month and leap years.
It seems you're considering a month to be 30 days since in your example you disregarded that May has 31 days, so why not just do the following?
SELECT DATEDIFF(DAY, '2009-04-16', '2009-05-15')/30
, DATEDIFF(DAY, '2009-04-16', '2009-05-16')/30
, DATEDIFF(DAY, '2009-04-16', '2009-06-16')/30
To capitalize, you can do the following with edit text:
To make first letter capital of every word:
android:inputType="textCapWords"
To make first letter capital of every sentence:
android:inputType="textCapSentences"
To make every letter capital:
android:inputType="textCapCharacters"
But this will only make changes to keyboard and user can change the mode to write letter in small case.
So this approach is not much appreciated if you really want the data in capitalize format, add following class first:
public class CapitalizeFirstLetter {
public static String capitaliseName(String name) {
String collect[] = name.split(" ");
String returnName = "";
for (int i = 0; i < collect.length; i++) {
collect[i] = collect[i].trim().toLowerCase();
if (collect[i].isEmpty() == false) {
returnName = returnName + collect[i].substring(0, 1).toUpperCase() + collect[i].substring(1) + " ";
}
}
return returnName.trim();
}
public static String capitaliseOnlyFirstLetter(String data)
{
return data.substring(0,1).toUpperCase()+data.substring(1);
}
}
And then,
Now to capitalize every word:
CapitalizeFirstLetter.capitaliseName(name);
To capitalize only first word:
CapitalizeFirstLetter.capitaliseOnlyFirstLetter(data);
You can get the current date in a locale-agnostic way using
for /f "skip=1" %%x in ('wmic os get localdatetime') do if not defined MyDate set MyDate=%%x
Then you can extract the individual parts using substrings:
set today=%MyDate:~0,4%-%MyDate:~4,2%-%MyDate:~6,2%
Another way, where you get variables that contain the individual parts, would be:
for /f %%x in ('wmic path win32_localtime get /format:list ^| findstr "="') do set %%x
set today=%Year%-%Month%-%Day%
Much nicer than fiddling with substrings, at the expense of polluting your variable namespace.
If you need UTC instead of local time, the command is more or less the same:
for /f %%x in ('wmic path win32_utctime get /format:list ^| findstr "="') do set %%x
set today=%Year%-%Month%-%Day%
You do not have to install urllib3
. You can choose any HTTP-request-making library that fits your needs and feed the response to BeautifulSoup
. The choice is though usually requests
because of the rich feature set and convenient API. You can install requests
by entering pip install requests
in the command line. Here is a basic example:
from bs4 import BeautifulSoup
import requests
url = "url"
response = requests.get(url)
soup = BeautifulSoup(response.content, "html.parser")
In our case, it was a Ciphers negotiation problem. We were getting this error randomly. We solved our problem by forcing a Cipher like this:
$soapClient = new SoapClient ('http://example.com/soap.asmx?wsdl',
array (
"stream_context" => stream_context_create (
array (
'ssl' => array (
'ciphers'=>'AES256-SHA'
)
)
)
)
);
Looks like PHP wasn't negotiating the same Ciphers at each service call.
Here you go. :D

You mention that you are doing this because IE doesn't support SVG.
The good news is that IE does support vector graphics. Okay, so it's in the form of a language called VML which only IE supports, rather than SVG, but it is there, and you can use it.
Google Maps, among others, will detect the browser capabilities to determine whether to serve SVG or VML.
Then there's the Raphael library, which is a Javascript browswer-based graphics library, which supports either SVG or VML, again depending on the browser.
Another one which may help: SVGWeb.
All of which means that you can support your IE users without having to resort to bitmap graphics.
See also the top answer to this question, for example: XSL Transform SVG to VML

I've had trouble with git revert in the past (mainly because I'm not quite certain how it works.) I've had trouble reverting because of merge problems..
My simple solution is this.
Step 1.
git clone <your repos URL> .
your project in another folder, then:
Step 2.
git reset --hard <the commit you wanna go to>
then Step 3.
in your latest (and main) project dir (the one that has the problematic last commit) paste the files of step 2
Step 4.
git commit -m "Fixing the previous messy commit"
Step 5.

Microsoft just announced .NET Core v 3.0, which is a much-improved version of .NET Core.
For more details visit this great article: Difference Between .NET Framework and .NET Core from April 2019.
I created the following Method to create reusable One Liner:
public void oneMethodToCloseThemAll(ResultSet resultSet, Statement statement, Connection connection) {
if (resultSet != null) {
try {
if (!resultSet.isClosed()) {
resultSet.close();
}
} catch (SQLException e) {
e.printStackTrace();
}
}
if (statement != null) {
try {
if (!statement.isClosed()) {
statement.close();
}
} catch (SQLException e) {
e.printStackTrace();
}
}
if (connection != null) {
try {
if (!connection.isClosed()) {
connection.close();
}
} catch (SQLException e) {
e.printStackTrace();
}
}
}
I use this Code in a parent Class thats inherited to all my classes that send DB Queries. I can use the Oneliner on all Queries, even if i do not have a resultSet.The Method takes care of closing the ResultSet, Statement, Connection in the correct order. This is what my finally block looks like.
finally {
oneMethodToCloseThemAll(resultSet, preStatement, sqlConnection);
}
Let's say I have code in the directory ~/local_dir/myNewApp
, and I want to put it under 'https://svn.host/existing_path/myNewApp' (while being able to ignore some binaries, vendor libraries, etc.).
svn mkdir https://svn.host/existing_path/myNewApp
cd ~/local_dir
svn co https://svn.host/existing_path/myNewApp
. If your folder has a different name locally than in the repository, you must specify it as an additional argument.svn st
will now show all your files as ?
, which means that they are not currently under revision controlsvn add
on files you want to add to the repository, and add others to svn:ignore

or --depth empty
, when you want selectively add only some files/folders.svn ci
You may find that gnuplot's for loops are useful in this case, if you adjust your filenames or graph titles appropriately.
e.g.
filenames = "first second third fourth fifth"
plot for [file in filenames] file."dat" using 1:2 with lines
and
filename(n) = sprintf("file_%d", n)
plot for [i=1:10] filename(i) using 1:2 with lines
It might be related to corruption in Angular Packages or incompatibility of packages.
Please follow the below steps to solve the issue.
Update
ASP.NET Boilerplate suggests here to use yarn because npm has some problems. It is slow and can not consistently resolve dependencies, yarn solves those problems and it is compatible to npm as well.
Quick little solution in pure js, no plugins needed:
function replaceQueryParam(param, newval, search) {
var regex = new RegExp("([?;&])" + param + "[^&;]*[;&]?");
var query = search.replace(regex, "$1").replace(/&$/, '');
return (query.length > 2 ? query + "&" : "?") + (newval ? param + "=" + newval : '');
}
Call it like this:
window.location = '/mypage' + replaceQueryParam('rows', 55, window.location.search)
Or, if you want to stay on the same page and replace multiple params:
var str = window.location.search
str = replaceQueryParam('rows', 55, str)
str = replaceQueryParam('cols', 'no', str)
window.location = window.location.pathname + str
edit, thanks Luke: To remove the parameter entirely, pass false
or null
for the value: replaceQueryParam('rows', false, params)
. Since 0
is also falsy, specify '0'
.
One of the approaches may be like this:
1) Create a CSS file with name "style.css" and define an id selector in it:
#pane{ -fx-background-image: url("background_image.jpg"); -fx-background-repeat: stretch; -fx-background-size: 900 506; -fx-background-position: center center; -fx-effect: dropshadow(three-pass-box, black, 30, 0.5, 0, 0); }
2) Set the id of the most top control (or any control) in the scene with value defined in CSS and load this CSS file into the scene:
public class Test extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
StackPane root = new StackPane();
root.setId("pane");
Scene scene = new Scene(root, 300, 250);
scene.getStylesheets().addAll(this.getClass().getResource("style.css").toExternalForm());
primaryStage.setScene(scene);
primaryStage.show();
}
}
You can also give an id to the control in a FXML file:
<StackPane id="pane" prefHeight="200" prefWidth="320" xmlns:fx="http://javafx.com/fxml" fx:controller="demo.Sample">
<children>
</children>
</StackPane>
For more info about JavaFX CSS Styling refer to this guide.
You can use .equals
for columns or entire dataframes.
df['col1'].equals(df['col2'])
If they're equal, that statement will return True
, else False
.
For Safari 12 and later, you can try the JSONBeautifier bookmarklet. Also works with other browsers.
I created this because JSON Formatter for Safari stopped working in Safari 12. There are a few new options for Safari 12, but I didn't find an open source one in the App Store, and I do not trust closed source browser extensions.
This can be used as a bookmarklet or the source, json-beautifier.js, can be copied and pasted into the browser console. The code is freely available for review and is less than 100 lines of code including comments. Runs entirely on your device and never sends your data over a network.
Works with local files too.
It is because of the endlines in each lines. Use the chomp method in ruby to delete the endline '\n' or 'r' at the end.
line_num=0
File.open('xxx.txt').each do |line|
print "#{line_num += 1} #{line.chomp}"
end
Just for anyone who still has an issue, I also had an issue where I typed ngif
rather than ngIf
(notice the capital 'I').
The only way is to highlight the lines to comment and press
ctrl + k, ctrl + c
or after highlighted press the toolbar option to comment out the selected lines.
The icons look like this
Creating a .bashrc file in your home directory also works. That way you don't have to copy your .bash_profile every time you install a new version of git bash.
You didn't provide many relevant details so I will guess that you called getInvoice
and then you used result object to set some values and call save
with assumption that your object changes will be saved.
However, persist
operation is intended for brand new transient objects and it fails if id is already assigned. In your case you probably want to call saveOrUpdate
instead of persist
.
You can find some discussion and references here "detached entity passed to persist error" with JPA/EJB code
Stepping on the answer of @Brian Cline I thought I might give my 5 cents

.list-inline class in bootstrap is a Inline Unordered List.
If you want to create a horizontal menu using ordered or unordered list you need to place all list items in a single line i.e. side by side. You can do this by simply applying the class
<div class="list-inline">
<a href="#" class="list-inline-item">First item</a>
<a href="#" class="list-inline-item">Secound item</a>
<a href="#" class="list-inline-item">Third item</a>
</div>
This variant is better because you could not know whether file exists or not. You should send correct header when you know for certain that you can read contents of your file. Also, if you have branches of code that does not finish with '.end()', browser will wait until it get them. In other words, your browser will wait a long time.
var fs = require("fs");
var filename = "./index.html";
function start(resp) {
fs.readFile(filename, "utf8", function(err, data) {
if (err) {
// may be filename does not exists?
resp.writeHead(404, {
'Content-Type' : 'text/html'
});
// log this error into browser
resp.write(err.toString());
resp.end();
} else {
resp.writeHead(200, {
"Content-Type": "text/html"
});
resp.write(data.toString());
resp.end();
}
});
}
You could just get the input value in the onclick-event like so:
onclick="execute(document.getElementById('textbox1').value);"
You would of course have to add an id to your textbox
I think you had the correct idea with your last example. You only got an error because you were trying to put quotes inside an already quoted string. This will fix it:
gci -path hklm:\software\microsoft\windows\currentversion\uninstall | ForEach-Object -Process { write-output ($_.GetValue("DisplayName") + "`n") }
Edit: Keith's $() operator actually creates a better syntax (I always forget about this one). You can also escape quotes inside quotes as so:
gci -path hklm:\software\microsoft\windows\currentversion\uninstall | ForEach-Object -Process { write-output "$($_.GetValue(`"DisplayName`"))`n" }
return await Task.FromResult(new MyClass());
Use the valgrind option --track-origins=yes
to have it track the origin of uninitialized values. This will make it slower and take more memory, but can be very helpful if you need to track down the origin of an uninitialized value.
Update: Regarding the point at which the uninitialized value is reported, the valgrind manual states:
It is important to understand that your program can copy around junk (uninitialised) data as much as it likes. Memcheck observes this and keeps track of the data, but does not complain. A complaint is issued only when your program attempts to make use of uninitialised data in a way that might affect your program's externally-visible behaviour.
From the Valgrind FAQ:
As for eager reporting of copies of uninitialised memory values, this has been suggested multiple times. Unfortunately, almost all programs legitimately copy uninitialised memory values around (because compilers pad structs to preserve alignment) and eager checking leads to hundreds of false positives. Therefore Memcheck does not support eager checking at this time.
You can make Inheritance Inversion (look it up here: https://medium.com/@franleplant/react-higher-order-components-in-depth-cf9032ee6c3e). That way you have access to instance of the component that you would be wrapping (thus you'll be able to access it's functions)
no, there is no way to make array length dynamic in java. you can use ArrayList
or other List
implementations instead.

If you want to notify your JTable
about changes of your data, use
tableModel.fireTableDataChanged()
From the documentation:
Notifies all listeners that all cell values in the table's rows may have changed. The number of rows may also have changed and the JTable should redraw the table from scratch. The structure of the table (as in the order of the columns) is assumed to be the same.
If you're having some problem about "error compiler of class file", it's possible to resolve this by changing the project's JRE to its correspondent through Eclipse.

If you want to do repeated testing for various keys against the same source, you can use functools.partial to create a new function variable, using a "partially complete" argument list, that is, specifying the seq, but omitting the item to search for:
from functools import partial
dups_in_source = partial(list_duplicates_of, source)
for c in "ABDEFS":
print(c, dups_in_source(c))
Prints:
A [0, 2, 6, 7, 16, 20]
B [1, 3, 5, 11, 15, 22]
D [4, 9]
E [8, 13]
F [17, 21]
S [10, 19]
execute
show VARIABLES like "%char%”;
find character-set-server if is not utf8mb4.
set it in your my.cnf, like
vim /etc/my.cnf
add one line
character_set_server = utf8mb4
at last restart mysql
I had the same problem with an Ubuntu Linux server running subversion when accessed via Eclipse.
It has shown that the problem had to do with a warning when Apache (re)started:
[Mon Jun 30 22:27:10 2014] [warn] NameVirtualHost *:80 has no VirtualHosts
... waiting [Mon Jun 30 22:27:11 2014] [warn] NameVirtualHost *:80 has no VirtualHosts
This has been due to a new entry in ports.conf
, where another NameVirtualHost
directive was entered alongside the directive in sites-enabled/000-default
.
After removing the directive in ports.conf
, the problem had vanished (after restarting Apache, naturally)
All a [self.navigationController pushViewController:controller animated:YES];
does is animate a transition, and add it to the navigation controller stack, and some other cool navigation bar animation stuffs. If you don't care about the bar animation, then this code should work. The bar does appear on the new controller, and you get an interactive pop gesture!
//Make Controller
DetailViewController *controller = [[DetailViewController alloc] initWithNibName:nil
bundle:[NSBundle mainBundle]];
//Customize presentation
controller.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
controller.modalPresentationStyle = UIModalPresentationCurrentContext;
//Present controller
[self presentViewController:controller
animated:YES
completion:nil];
//Add to navigation Controller
[self navigationController].viewControllers = [[self navigationController].viewControllers arrayByAddingObject:controller];
//You can't just [[self navigationController].viewControllers addObject:controller] because viewControllers are for some reason not a mutable array.
Edit: Sorry, presentViewController will fill the full screen. You will need to make a custom transition, with CGAffineTransform.translation or something, animate the controller with the transition, then add it to the navigationController's viewControllers.
There's more to it than this, but you're probably looking for this list:

You can use the TelephonyManager
to do this:
TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
String number = tm.getLine1Number();
The documentation for getLine1Number()
says this method will return null
if the number is "unavailable", but it does not say when the number might be unavailable.
You'll need to give your application permission to make this query by adding the following to your Manifest:
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
(You shouldn't use TelephonyManager.getDefault()
to get the TelephonyManager
as that is a private undocumented API call and may change in future.)
For this particular case, if using re
module is overkill, how about using split
(or rsplit
) method as
se='</html>'
z.write(article.split(se)[0]+se)
For example,
#!/usr/bin/python
article='''<html>Larala
Ponta Monta
</html>Kurimon
Waff Moff
'''
z=open('out.txt','w')
se='</html>'
z.write(article.split(se)[0]+se)
outputs out.txt
as
<html>Larala
Ponta Monta
</html>
Have you ever heard of Promises? They work on all modern browsers and are relatively simple to use. Have a look at this simple method to inject css to the html head:
function loadStyle(src) {
return new Promise(function (resolve, reject) {
let link = document.createElement('link');
link.href = src;
link.rel = 'stylesheet';
link.onload = () => resolve(link);
link.onerror = () => reject(new Error(`Style load error for ${src}`));
document.head.append(link);
});
}
You can implement it as follows:
window.onload = function () {
loadStyle("https://fonts.googleapis.com/css2?family=Raleway&display=swap")
.then(() => loadStyle("css/style.css"))
.then(() => loadStyle("css/icomoon.css"))
.then(() => {
alert('All styles are loaded!');
}).catch(err => alert(err));
}
It's really cool, right? This is a way to decide the priority of the styles using Promises.
To see a multi-style loading implementation see: https://stackoverflow.com/a/63936671/13720928
What I wanted is a table like this
I added this in my styles.xml :

It’s a holdover from the Netscape days:
Missing digits are treated as 0[...]. An incorrect digit is simply interpreted as 0. For example the values #F0F0F0, F0F0F0, F0F0F, #FxFxFx and FxFxFx are all the same.
It is from the blog post A little rant about Microsoft Internet Explorer's color parsing which covers it in great detail, including varying lengths of color values, etc.
If we apply the rules in turn from the blog post, we get the following:
Replace all nonvalid hexadecimal characters with 0’s:
chucknorris becomes c00c0000000
Pad out to the next total number of characters divisible by 3 (11 ? 12):
c00c 0000 0000
Split into three equal groups, with each component representing the corresponding colour component of an RGB colour:
RGB (c00c, 0000, 0000)
Truncate each of the arguments from the right down to two characters.
Which, finally, gives the following result:
RGB (c0, 00, 00) = #C00000 or RGB(192, 0, 0)
Here’s an example demonstrating the bgcolor
attribute in action, to produce this “amazing” colour swatch:
<table>
<tr>
<td bgcolor="chucknorris" cellpadding="8" width="100" align="center">chuck norris</td>
<td bgcolor="mrt" cellpadding="8" width="100" align="center" style="color:#ffffff">Mr T</td>
<td bgcolor="ninjaturtle" cellpadding="8" width="100" align="center" style="color:#ffffff">ninjaturtle</td>
</tr>
<tr>
<td bgcolor="sick" cellpadding="8" width="100" align="center">sick</td>
<td bgcolor="crap" cellpadding="8" width="100" align="center">crap</td>
<td bgcolor="grass" cellpadding="8" width="100" align="center">grass</td>
</tr>
</table>
_x000D_
This also answers the other part of the question: Why does bgcolor="chucknorr"
produce a yellow colour? Well, if we apply the rules, the string is:
c00c00000 => c00 c00 000 => c0 c0 00 [RGB(192, 192, 0)]
Which gives a light yellow gold colour. As the string starts off as 9 characters, we keep the second ‘C’ this time around, hence it ends up in the final colour value.
I originally encountered this when someone pointed out that you could do color="crap"
and, well, it comes out brown.
In Android Studio you can add Hint (Place holder) through GUI. First select EditText field on designer view. Then Click on Component Tree Left side of IDE (Normally it's there, but it may be there minimized) There you can see Properties of selected EditText. Find Hint field as below Image
There you can add Hint(Place holder) to EditText
I'm using Sublime portable version (for Windows) and this (placing the mousemap in SublimeText\Packages\User
folder) did not work for me.
I had to place the mousemap file in SublimeText\Data\Packages\User
folder to get it to work where SublimeText
is the installation directory for my portable version. Data\Packages\User
is where I found the keymap file as well.
All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.
If you have accidentally removed DLL file from php/ext
folder, just add it back (get the copy from XAMPP zip archive - its downloadable).
If you have deleted the accompanying INI configuration line from php.ini
file, add it back as well:
extension=php_mbstring.dll
Also, ensure to restart your webserver (Apache) using XAMPP control panel.

)There are several ways to add files to an existing Java project in Eclipse. So lets assume you have already created the Java project in Eclipse (e.g. using File
-> New
-> Project...
- and select Java project
).
To get Java files into the new project you can do any of the following. Note that there are other ways as well. The sequence is my preference.
Navigator
view directly from the native file manager. You must create any needed Java packages first. This method is best for a few files in an existing Java package.File
-> Import...
- select File System
. Here you can then select exactly which files to import into the new project and in which Java package to put them. This is extremely handy if you want to import many files or there are multiple Java packages.File
-> Refresh
to refresh the Eclipse view of the native system. Remember to select the new project before the refresh.The last one is what you did - minus the refresh...
Try
string reversed(temp.rbegin(), temp.rend());
EDIT: Elaborating as requested.
string::rbegin()
and string::rend()
, which stand for "reverse begin" and "reverse end" respectively, return reverse iterators into the string. These are objects supporting the standard iterator interface (operator*
to dereference to an element, i.e. a character of the string, and operator++
to advance to the "next" element), such that rbegin()
points to the last character of the string, rend()
points to the first one, and advancing the iterator moves it to the previous character (this is what makes it a reverse iterator).
Finally, the constructor we are passing these iterators into is a string constructor of the form:
template <typename Iterator>
string(Iterator first, Iterator last);
which accepts a pair of iterators of any type denoting a range of characters, and initializes the string to that range of characters.
for those searching for an alternative to $result = $stmt->get_result()
I've made this function which allows you to mimic the $result->fetch_assoc()
but using directly the stmt object:
function fetchAssocStatement($stmt)
{
if($stmt->num_rows>0)
{
$result = array();
$md = $stmt->result_metadata();
$params = array();
while($field = $md->fetch_field()) {
$params[] = &$result[$field->name];
}
call_user_func_array(array($stmt, 'bind_result'), $params);
if($stmt->fetch())
return $result;
}
return null;
}
as you can see it creates an array and fetches it with the row data, since it uses $stmt->fetch()
internally, you can call it just as you would call mysqli_result::fetch_assoc
(just be sure that the $stmt
object is open and result is stored):
//mysqliConnection is your mysqli connection object
if($stmt = $mysqli_connection->prepare($query))
{
$stmt->execute();
$stmt->store_result();
while($assoc_array = fetchAssocStatement($stmt))
{
//do your magic
}
$stmt->close();
}
This seems to be the right thing to do, according to the Safari HTML Reference:
<meta name="format-detection" content="telephone=no">
If you disable this but still want telephone links, you can still use the "tel" URI scheme.
Here is the relevant page at Apple's Developer Library.
I might be misunderstanding your question, so apologies if I am.
If you're looking for the words "Quid", "Application Number", etc. to be bold, just wrap them in <strong>
tags:
<strong>Quid</strong>: ...
Hope that helps!
Yep, even in plain JavaScript it's pretty easy. You give an element an id and then you can use that as a "bookmark":
<div id="here">here</div>
If you want it to scroll there when a user clicks a link, you can just use the tried-and-true method:
<a href="#here">scroll to over there</a>
To do it programmatically, use scrollIntoView()
document.getElementById("here").scrollIntoView()
In a Firebird database the AFTER myOtherColumn
does not work but you can try re-positioning the column using:
ALTER TABLE name ALTER column POSITION new_position
I guess it may work in other cases as well.
Somewhat late to the party - I was doing something similar and needed some pointers and ended up here. Taking no credit - I took all of the code from Brice but got the "zero interactions" than Cengiz got.
Using guidance from what jheriks amd Joseph Lust had put I think I know why - I had my object under test as a field and newed it up in a @Before unlike Brice. Then the actual logger was not the mock but a real class init'd as jhriks suggested...
I would normally do this for my object under test so as to get a fresh object for each test. When I moved the field to a local and newed it in the test it ran ok. However, if I tried a second test it was not the mock in my test but the mock from the first test and I got the zero interactions again.
When I put the creation of the mock in the @BeforeClass the logger in the object under test is always the mock but see the note below for the problems with this...
Class under test
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class MyClassWithSomeLogging {
private static final Logger LOG = LoggerFactory.getLogger(MyClassWithSomeLogging.class);
public void doStuff(boolean b) {
if(b) {
LOG.info("true");
} else {
LOG.info("false");
}
}
}

@RunWith(PowerMockRunner.class)
@PrepareForTest({LoggerFactory.class})
public class MyClassWithSomeLoggingTest {
private static Logger mockLOG;
@BeforeClass
public static void setup() {
mockStatic(LoggerFactory.class);
mockLOG = mock(Logger.class);
when(LoggerFactory.getLogger(any(Class.class))).thenReturn(mockLOG);
}
@Test
public void testIt() {
MyClassWithSomeLogging myClassWithSomeLogging = new MyClassWithSomeLogging();
myClassWithSomeLogging.doStuff(true);
verify(mockLOG, times(1)).info("true");
}
@Test
public void testIt2() {
MyClassWithSomeLogging myClassWithSomeLogging = new MyClassWithSomeLogging();
myClassWithSomeLogging.doStuff(false);
verify(mockLOG, times(1)).info("false");
}
@AfterClass
public static void verifyStatic() {
verify(mockLOG, times(1)).info("true");
verify(mockLOG, times(1)).info("false");
verify(mockLOG, times(2)).info(anyString());
}
}
Note
If you have two tests with the same expectation I had to do the verify in the @AfterClass as the invocations on the static are stacked up - verify(mockLOG, times(2)).info("true");
- rather than times(1) in each test as the second test would fail saying there where 2 invocation of this. This is pretty pants but I couldn't find a way to clear the invocations. I'd like to know if anyone can think of a way round this....
You cannot TRUNCATE
a table that has FK constraints applied on it (TRUNCATE
is not the same as DELETE
).
To work around this, use either of these solutions. Both present risks of damaging the data integrity.
Option 1:
TRUNCATE
Option 2: suggested by user447951 in their answer
SET FOREIGN_KEY_CHECKS = 0;
TRUNCATE table $table_name;
SET FOREIGN_KEY_CHECKS = 1;
When you're creating the table, you can create an IDENTITY
column as follows:
CREATE TABLE (
ID_column INT NOT NULL IDENTITY(1,1) PRIMARY KEY,
...
);
The IDENTITY
property will auto-increment the column up from number 1. (Note that the data type of the column has to be an integer.) If you want to add this to an existing column, use an ALTER TABLE
command.
Edit:
Tested a bit, and I can't find a way to change the Identity properties via the Column Properties window for various tables. I guess if you want to make a column an identity column, you HAVE to use an ALTER TABLE
command.
In MySQL, It should be like this
INSERT INTO this_table_archive (col1, col2, ..., coln)
SELECT col1, col2, ..., coln
FROM this_table
WHERE entry_date < '2011-01-01 00:00:00';
As MrFancypants mentioned in the comments, if you are using Jupyter (which you should, since it currently supersedes the older IPython Notebook project), things are a little different. For one, there are no profiles any more.
After installing Jupyter, first check your ~/.jupyter folder to see its content. If no config files were migrated from the default IPython profile (as they weren't in my case), create a new one for Jupyter Notebook:
jupyter notebook --generate-config
This generates ~/.jupyter/jupyter_notebook_config.py file with some helpfully commented possible options. To set the default directory add:
c.NotebookApp.notebook_dir = u'/absolute/path/to/notebook/directory'
As I switch between Linux and OS X, I wanted to use a path relative to my home folder (as they differ – /Users/username and /home/username), so I set something like:
import os
c.NotebookApp.notebook_dir = os.path.expanduser('~/Dropbox/dev/notebook')
Now, whenever I run jupyter notebook
, it opens my desired notebook folder. I also version the whole ~/.jupyter folder in my dotfiles repository that I deploy to every new work machine.
As an aside, you can still use the --notebook-dir
command line option, so maybe a simple alias would suit your needs better.
jupyter notebook --notebook-dir=/absolute/path/to/notebook/directory

Initially go to your home and press Ctrl + H it will show you hidden files now look for .bashrc
file, open it with any text editor then place below lines at the end of file.
export ANDROID_HOME=/home/varun/Android/Sdk
export PATH=$PATH:/home/varun/Android/Sdk/tools
export PATH=$PATH:/home/varun/Android/Sdk/platform-tools
Please change /home/varun/Android/Sdk
path to your SDK path.
Do the same for tools and platform-tools.
After this save .bashrc
file and close it.
Now you are ready to use ADB commands on terminal.
This demo is returning correctly for me in Chrome 14, FF3 and FF5 (with Firebug):

console.log(mytextvalue == null); // false
and changing the console.log
to alert

In my case, cannot open some websites or after openned IE8 gave "cannot return to website error". After some visits to MS help sites like this and followed all the instructioms with no avail I saw what seems to me a tip.
In one of the MS websites they say to delete old Java versions using "control panel" and "add remove programs". I did just that but only saw one version of Java v.6u22. Then I got the idea of download the last version of Java from some days ago v.6u29 and voila... IE8 is working now and seems OK. I'm writing this in the hope this can help others.
The quickest way I found is through editing mode:
yy
to copy the line.dd
to delete the line.p
to paste the line.I was looking for in place solution to this problem. This solves the purpose in O(k).
def solution(self, list, k):
r=len(list)-1
i = 0
while i<k:
temp = list[0]
list[0:r] = list[1:r+1]
list[r] = temp

It sounds like you already know the unique column names. If that's the case, then df = df['Time', 'Time Relative', 'N2']
would work.
If not, your solution should work:
In [101]: vals = np.random.randint(0,20, (4,3))
vals
Out[101]:
array([[ 3, 13, 0],
[ 1, 15, 14],
[14, 19, 14],
[19, 5, 1]])
In [106]: df = pd.DataFrame(np.hstack([vals, vals]), columns=['Time', 'H1', 'N2', 'Time Relative', 'N2', 'Time'] )
df
Out[106]:
Time H1 N2 Time Relative N2 Time
0 3 13 0 3 13 0
1 1 15 14 1 15 14
2 14 19 14 14 19 14
3 19 5 1 19 5 1
In [107]: df.T.drop_duplicates().T
Out[107]:
Time H1 N2
0 3 13 0
1 1 15 14
2 14 19 14
3 19 5 1
You probably have something specific to your data that's messing it up. We could give more help if there's more details you could give us about the data.
Edit: Like Andy said, the problem is probably with the duplicate column titles.
For a sample table file 'dummy.csv' I made up:
Time H1 N2 Time N2 Time Relative
3 13 13 3 13 0
1 15 15 1 15 14
14 19 19 14 19 14
19 5 5 19 5 1
using read_table
gives unique columns and works properly:
In [151]: df2 = pd.read_table('dummy.csv')
df2
Out[151]:
Time H1 N2 Time.1 N2.1 Time Relative
0 3 13 13 3 13 0
1 1 15 15 1 15 14
2 14 19 19 14 19 14
3 19 5 5 19 5 1
In [152]: df2.T.drop_duplicates().T
Out[152]:
Time H1 Time Relative
0 3 13 0

A gem like https://rubygems.org/gems/to_bool can be used, but it can easily be written in one line using a regex or ternary.
regex example:
boolean = (var.to_s =~ /^true$/i) == 0
ternary example:
boolean = var.to_s.eql?('true') ? true : false
The advantage to the regex method is that regular expressions are flexible and can match a wide variety of patterns. For example, if you suspect that var could be any of "True", "False", 'T', 'F', 't', or 'f', then you can modify the regex:
boolean = (var.to_s =~ /^[Tt].*$/i) == 0
You can also use IFNA(expression, value)
I was facing a problem in installing a non conda package on anaconda, I followed the most liked answer here and it didn't go well (maybe because my anaconda is in F directory and env created was in C and bin folder was not created, I have no idea but it didn't work).
According to anaconda pip is already installed ( which is found using the command "conda list
" on anaconda prompt), but pip packages were not getting installed so here is what I did, I installed pip again and then pip installed the package.
conda install pip
pip install see

I had to install IIS Media Services 4.1 from the Windows Web App Gallery.
Yes, it's a common misconception that Regular Expressions can match only regular languages. In fact, the PCRE functions can match much more than regular languages, they can match even some non-context-free languages! Wikipedia's article on RegExps has a special section about it.
JSON can be recognized using PCRE in several ways! @mario showed one great solution using named subpatterns and back-references. Then he noted that there should be a solution using recursive patterns (?R)
. Here is an example of such regexp written in PHP:
$regexString = '"([^"\\\\]*|\\\\["\\\\bfnrt\/]|\\\\u[0-9a-f]{4})*"';
$regexNumber = '-?(?=[1-9]|0(?!\d))\d+(\.\d+)?([eE][+-]?\d+)?';
$regexBoolean= 'true|false|null'; // these are actually copied from Mario's answer
$regex = '/\A('.$regexString.'|'.$regexNumber.'|'.$regexBoolean.'|'; //string, number, boolean
$regex.= '\[(?:(?1)(?:,(?1))*)?\s*\]|'; //arrays
$regex.= '\{(?:\s*'.$regexString.'\s*:(?1)(?:,\s*'.$regexString.'\s*:(?1))*)?\s*\}'; //objects
$regex.= ')\Z/is';
I'm using (?1)
instead of (?R)
because the latter references the entire pattern, but we have \A
and \Z
sequences that should not be used inside subpatterns. (?1)
references to the regexp marked by the outermost parentheses (this is why the outermost ( )
does not start with ?:
). So, the RegExp becomes 268 characters long :)
/\A("([^"\\]*|\\["\\bfnrt\/]|\\u[0-9a-f]{4})*"|-?(?=[1-9]|0(?!\d))\d+(\.\d+)?([eE][+-]?\d+)?|true|false|null|\[(?:(?1)(?:,(?1))*)?\s*\]|\{(?:\s*"([^"\\]*|\\["\\bfnrt\/]|\\u[0-9a-f]{4})*"\s*:(?1)(?:,\s*"([^"\\]*|\\["\\bfnrt\/]|\\u[0-9a-f]{4})*"\s*:(?1))*)?\s*\})\Z/is
Anyway, this should be treated as a "technology demonstration", not as a practical solution. In PHP I'll validate the JSON string with calling the json_decode()
function (just like @Epcylon noted). If I'm going to use that JSON (if it's validated), then this is the best method.
You can do by maintaining the state as below:
$('#user_button').on('click',function(){
if($(this).attr('data-click-state') == 1) {
$(this).attr('data-click-state', 0);
$(this).css('background-color', 'red')
}
else {
$(this).attr('data-click-state', 1);
$(this).css('background-color', 'orange')
}
});
This below code will give selected row, you can parse the values from it and send to the AJAX call.
$(".selected").click(function () {
var row = $(this).parent().parent().parent().html();
});
q = [1, 2, 3, 4, 1, 2, 5, 1, 2, 3, 4, 5]
vm = [-1, -1, -1, -1,1,2,3,1]
p = []
for v in vm:
if v in q:
p.append(q.index(v))
else:
p.append(99999)
print p
p = [q.index(v) if v in q else 99999 for v in vm]
print p
Output:
[99999, 99999, 99999, 99999, 0, 1, 2, 0]
[99999, 99999, 99999, 99999, 0, 1, 2, 0]
Instead of using append()
in the list comprehension you can reference the p as direct output, and use q.index(v)
and 99999
in the LC.
Not sure if this is intentional but note that q.index(v)
will find just the first occurrence of v
, even tho you have several in q
. If you want to get the index of all v
in q
, consider using a enumerator
and a list of already visited indexes
Something in those lines(pseudo-code):
visited = []
for i, v in enumerator(vm):
if i not in visited:
p.append(q.index(v))
else:
p.append(q.index(v,max(visited))) # this line should only check for v in q after the index of max(visited)
visited.append(i)
In a HashMap
the key is an object, that contains hashCode()
and equals(Object)
methods.
When you insert a new entry into the Map, it checks whether the hashCode
is already known. Then, it will iterate through all objects with this hashcode, and test their equality with .equals()
. If an equal object is found, the new value replaces the old one. If not, it will create a new entry in the map.
Usually, talking about maps, you use collision when two objects have the same hashCode
but they are different. They are internally stored in a list.
This worked for me:
jQuery('#tblPaging').dataTable({
"sort": true,
"pageLength": 20
});
A File object in Java is a representation of a path to a directory or file, not the file itself. You don't need to have write access to the filesystem to create a File
object, you only need it if you intend to actually write to the file (using a FileOutputStream for example)
Another solution which is permanent in nature between sessions without requiring you to run a specific command when opening chrome is as follows:
I came up with a solution for dataframes with arbitrary numbers of columns (while still only separating one column's entries at a time).
def splitDataFrameList(df,target_column,separator):
''' df = dataframe to split,
target_column = the column containing the values to split
separator = the symbol used to perform the split
returns: a dataframe with each entry for the target column separated, with each element moved into a new row.
The values in the other columns are duplicated across the newly divided rows.
'''
def splitListToRows(row,row_accumulator,target_column,separator):
split_row = row[target_column].split(separator)
for s in split_row:
new_row = row.to_dict()
new_row[target_column] = s
row_accumulator.append(new_row)
new_rows = []
df.apply(splitListToRows,axis=1,args = (new_rows,target_column,separator))
new_df = pandas.DataFrame(new_rows)
return new_df
According to ALL THE SPECS DATING BACK TO 1996, percentage values on font-size
refer to the parent element's (computed) font-size.
<style>
div {
font-size: 16px;
}
span {
font-size: 75%;
}
</style>
<div><span>this font size is 12px!</span></div>
It's that easy.
What if the div
declares a relative font-size, like em
s, or even worse, another percentage?? See “computed” above. Whatever absolute unit the relative unit converts to.
The only question that remains is what happens when you use a percentage value on the root element, which has no parent:
html {
font-size: 62.5%; /* 62.5% of what? */
}
In that case, see the “duplicate” of this question. TLDR: percentages on the root element refer to the browser default font size, which might be different per user.

we have just made an enum extension for c# https://github.com/simonmau/enum_ext
It's just a implementation for the typesafeenum, but it works great so we made a package to share - have fun with it

I know the example is kind of useless, but you get the idea ;)
Try:
String str = "my string \n my other string";
When printed you will get:
my string
my other string
In your case, the first value to insert must be NULL, because it's AUTO_INCREMENT.
Did they add a runtime List<> and/or Map<> type class to typepad 1.0
No, providing a runtime is not the focus of the TypeScript team.
is there a solid library out there someone wrote that provides this functionality?
I wrote (really just ported over buckets to typescript): https://github.com/basarat/typescript-collections
JavaScript / TypeScript now support this natively and you can enable them with lib.d.ts

An AXD file is a file used by ASP.NET applications for handling embedded resource requests. It contains instructions for retrieving embedded resources, such as images, JavaScript (.JS) files, and.CSS files.
AXD files are used for injecting resources into the client-side webpage and access them on the server in a standard way.
You need to use the border property as seen here: jsFiddle
HTML:
<table width="770">
<tr>
<td class="border-left-bottom">picture (border only to the left and bottom ) </td>
<td>text</td>
</tr>
<tr>
<td>text</td>
<td class="border-left-bottom">picture (border only to the left and bottom) </td>
</tr>
</table>`
CSS:
td.border-left-bottom{
border-left: solid 1px #000;
border-bottom: solid 1px #000;
}
If your goal is just to download the file there's a hassle-free application called gget
:
gget github.com/gohugoio/hugo 'hugo_extended_*_Linux-ARM.deb'
The above example would download single file from hugo
repository.

{ //Or if(true) if the language doesn't support making scopes like this
double intermediateResult;
for (int i=0; i<1000; i++) {
intermediateResult = i;
System.out.println(intermediateResult);
}
}
This way you only declare the variable once, and it'll die when you leave the loop.

Now, to your question:
how to compare two elements coming from xml as string
In Xpath 1.0 strings can be compared only for equality (or inequality), using the operator =
and the function not()
together with the operator =
.
$str1 = $str2
evaluates to true()
exactly when the string $str1
is equal to the string $str2
.
not($str1 = $str2)
evaluates to true()
exactly when the string $str1
is not equal to the string $str2
.
There is also the !=
operator. It generally should be avoided because it has anomalous behavior whenever one of its operands is a node-set.
Now, the rules for comparing two element nodes are similar:
$el1 = $el2
evaluates to true()
exactly when the string value of $el1
is equal to the string value of $el2
.
not($el1 = $el2)
evaluates to true()
exactly when the string value of $el1
is not equal to the string value of $el2
.
However, if one of the operands of =
is a node-set, then
$ns = $str
evaluates to true()
exactly when there is at least one node in the node-set $ns1
, whose string value is equal to the string $str
$ns1 = $ns2
evaluates to true()
exactly when there is at least one node in the node-set $ns1
, whose string value is equal to the string value of some node from $ns2
Therefore, the expression:
OU_NAME='OU_ADDR1'
evaluates to true()
only when there is at least one element child of the current node that is named OU_NAME
and whose string value is the string 'OU_ADDR1'.
This is obviously not what you want!
Most probably you want:
OU_NAME=OU_ADDR1
This expression evaluates to true
exactly there is at least one OU_NAME
child of the current node and one OU_ADDR1
child of the current node with the same string value.
Finally, in XPath 2.0, strings can be compared also using the value comparison operators lt
, le
, eq
, gt
, ge
and the inherited from XPath 1.0 general comparison operator =
.
Trying to evaluate a value comparison operator when one or both of its arguments is a sequence of more than one item results in error.

You can create a new MongoDB ObjectId
like this using mongoose:
var mongoose = require('mongoose');
var newId = new mongoose.mongo.ObjectId('56cb91bdc3464f14678934ca');
// or leave the id string blank to generate an id with a new hex identifier
var newId2 = new mongoose.mongo.ObjectId();

If your object is not polymorphic (and a stack implementation likely isn't), then as per other answers here, what you want is the copy constructor. Please note that there are differences between copy construction and assignment in C++; if you want both behaviors (and the default versions don't fit your needs), you'll have to implement both functions.
If your object is polymorphic, then slicing can be an issue and you might need to jump through some extra hoops to do proper copying. Sometimes people use as virtual method called clone() as a helper for polymorphic copying.
Finally, note that getting copying and assignment right, if you need to replace the default versions, is actually quite difficult. It is usually better to set up your objects (via RAII) in such a way that the default versions of copy/assign do what you want them to do. I highly recommend you look at Meyer's Effective C++, especially at items 10,11,12.
I've doing it with a function. In this case I will only transform character variables to factor:
for (i in 1:ncol(data)){
if(is.character(data[,i])){

}
use the code
cell.setCellType(Cell.CELL_TYPE_STRING);
before reading the string value, Which can help you.

You can see your current session settings by querying nls_session_parameters
:
select value
from nls_session_parameters
where parameter = 'NLS_NUMERIC_CHARACTERS';
VALUE
----------------------------------------
.,
That may differ from the database defaults, which you can see in nls_database_parameters
.
In this session your query errors:
select to_number('100,12') from dual;
Error report -
SQL Error: ORA-01722: invalid number
01722. 00000 - "invalid number"
I could alter my session, either directly with alter session
or by ensuring my client is configured in a way that leads to the setting the string needs (it may be inherited from a operating system or Java locale, for example):
alter session set NLS_NUMERIC_CHARACTERS = ',.';
select to_number('100,12') from dual;
TO_NUMBER('100,12')
-------------------
100,12
In SQL Developer you can set your preferred value in Tool->Preferences->Database->NLS.
But I can also override that session setting as part of the query, with the optional third nlsparam parameter to to_number()
; though that makes the optional second fmt parameter necessary as well, so you'd need to be able pick a suitable format:
alter session set NLS_NUMERIC_CHARACTERS = '.,';
select to_number('100,12', '99999D99', 'NLS_NUMERIC_CHARACTERS='',.''')
from dual;
TO_NUMBER('100,12','99999D99','NLS_NUMERIC_CHARACTERS='',.''')
--------------------------------------------------------------
100.12
By default the result is still displayed with my session settings, so the decimal separator is still a period.
uint16_t
is guaranteed to be a unsigned integer that is 16 bits large
unsigned short int
is guaranteed to be a unsigned short integer
, where short integer
is defined by the compiler (and potentially compiler flags) you are currently using. For most compilers for x86 hardware a short integer
is 16 bits large.
Also note that per the ANSI C standard only the minimum size of 16 bits is defined, the maximum size is up to the developer of the compiler
Minimum Type Limits
Any compiler conforming to the Standard must also respect the following limits with respect to the range of values any particular type may accept. Note that these are lower limits: an implementation is free to exceed any or all of these. Note also that the minimum range for a char is dependent on whether or not a char is considered to be signed or unsigned.

Not the most beautiful way of doing it I guess:
git log --pretty=oneline | wc -l
This gives you a number then
git log HEAD~<The number minus one>
The FETCH_HEAD is a reference to the tip of the last fetch, whether that fetch was initiated directly using the fetch command or as part of a pull. The current value of FETCH_HEAD is stored in the .git
folder in a file named, you guessed it, FETCH_HEAD
.
So if I issue:
git fetch https://github.com/ryanmaxwell/Fragaria
FETCH_HEAD may contain
3cfda7cfdcf9fb78b44d991f8470df56723658d3 https://github.com/ryanmaxwell/Fragaria
If I have the remote repo configured as a remote tracking branch then I can follow my fetch with a merge of the tracking branch. If I don't I can merge the tip of the last fetch directly using FETCH_HEAD.
git merge FETCH_HEAD

What about Console.Readline();
?
It depends on how precise you want the comparison to be. If you want to compare for exactly the same number, then just go with ==. (You almost never want to do this unless you actually want exactly the same number.) On any decent platform you can also do the following:
diff= a - b; return fabs(diff)<EPSILON;
as fabs
tends to be pretty fast. By pretty fast I mean it is basically a bitwise AND, so it better be fast.
And integer tricks for comparing doubles and floats are nice but tend to make it more difficult for the various CPU pipelines to handle effectively. And it's definitely not faster on certain in-order architectures these days due to using the stack as a temporary storage area for values that are being used frequently. (Load-hit-store for those who care.)
Try this,
table{
border-collapse: collapse; /* 'cellspacing' equivalent */
}
table td,
table th{
padding: 0; /* 'cellpadding' equivalent */
}
Try the read
shell builtin:
read -p "Continue (y/n)?" CONT
if [ "$CONT" = "y" ]; then
echo "yaaa";
else
echo "booo";
fi
You are making this too hard. If I understand what you are trying to do correctly, the built-in 'back' button and Android itself will do all the work for you: http://developer.android.com/guide/components/tasks-and-back-stack.html
Also, implementing a custom "back" button violates Core App Quality Guideline UX-N1: http://developer.android.com/distribute/googleplay/quality/core.html
To rebuild use:
ALTER INDEX __NAME_OF_INDEX__ ON __NAME_OF_TABLE__ REBUILD
or to reorganize use:
ALTER INDEX __NAME_OF_INDEX__ ON __NAME_OF_TABLE__ REORGANIZE
Reorganizing should be used at lower (<30%) fragmentations but only rebuilding (which is heavier to the database) cuts the fragmentation down to 0%.

Add XAttribute
in the constructor of the XElement
, like
new XElement("Conn", new XAttribute("Server", comboBox1.Text));
You can also add multiple attributes or elements via the constructor
new XElement("Conn", new XAttribute("Server", comboBox1.Text), new XAttribute("Database", combobox2.Text));
or you can use the Add-Method of the XElement
to add attributes
XElement element = new XElement("Conn");
XAttribute attribute = new XAttribute("Server", comboBox1.Text);
element.Add(attribute);
$string = "producturl.php?id=736375493?=tm";

Here's swift 3.0 solution based on answers above:
for (i, point) in allPoints.enumerated() {
let nextPoint = i == allPoints.count - 1 ? allPoints[0] : allPoints[i+1]
signedArea += (point.x * nextPoint.y - nextPoint.x * point.y)
}
let clockwise = signedArea < 0
For anyone else who gets caught, ensure setCustomAnimations is called before the call to replace/add when building the transaction.
The methodNotAllowed
exception indicates that a route doesn't exist for the HTTP method you are requesting.
Your form is set up to make a DELETE
request, so your route needs to use Route::delete()
to receive this.
Route::delete('empresas/eliminar/{id}', [
'as' => 'companiesDelete',
'uses' => 'CompaniesController@delete'
]);

If you're using mod_php, you can use apache_get_modules()
. This will return an array of all enabled modules, so to check if mod_rewrite
is enabled, you could simply do
in_array('mod_rewrite', apache_get_modules());
Unfortunately, you're most likely trying to do this with CGI, which makes it a little bit more difficult.
You can test it using the following, though
strpos(shell_exec('/usr/local/apache/bin/apachectl -l'), 'mod_rewrite') !== false
If the above condition evaluates to true
, then mod_write
is enabled.
I was having same issue, way i have resolved is:
opened the MySQL installer. i was having a Reconfigure link on MYSQL Server row.
Clicked on it, it does reinstalled MySQL Server. after that opened MySQL Workbench, and it was working fine.
Put simply
&
means the address-of, you will see that in placeholders for functions to modify the parameter variable as in C, parameter variables are passed by value, using the ampersand means to pass by reference.*
means the dereference of a pointer variable, meaning to get the value of that pointer variable.int foo(int *x){
*x++;
}
int main(int argc, char **argv){
int y = 5;
foo(&y); // Now y is incremented and in scope here
printf("value of y = %d\n", y); // output is 6
/* ... */
}
The above example illustrates how to call a function foo
by using pass-by-reference, compare with this
int foo(int x){
x++;
}
int main(int argc, char **argv){
int y = 5;
foo(y); // Now y is still 5
printf("value of y = %d\n", y); // output is 5
/* ... */
}
Here's an illustration of using a dereference
int main(int argc, char **argv){
int y = 5;
int *p = NULL;
p = &y;
printf("value of *p = %d\n", *p); // output is 5
}
The above illustrates how we got the address-of y
and assigned it to the pointer variable p
. Then we dereference p
by attaching the *
to the front of it to obtain the value of p
, i.e. *p
.
Three things: use the using

and prefix parameters with ? and add Allow User Variables=True
to the connection string.
string connString = ConfigurationManager.ConnectionStrings["default"].ConnectionString;
using (var conn = new MySqlConnection(connString))
{
conn.Open();
var comm = conn.CreateCommand();
comm.CommandText = "INSERT INTO room(person,address) VALUES(@person, @address)";
comm.Parameters.AddWithValue("?person", "Myname");
comm.Parameters.AddWithValue("?address", "Myaddress");
comm.ExecuteNonQuery();
}

Here is the best example of Cross Join and Inner Join.
Consider the following tables
TABLE : Teacher
x------------------------x
| TchrId | TeacherName |
x----------|-------------x
| T1 | Mary |
| T2 | Jim |
x------------------------x
TABLE : Student
x--------------------------------------x
| StudId | TchrId | StudentName |
x----------|-------------|-------------x
| S1 | T1 | Vineeth |
| S2 | T1 | Unni |
x--------------------------------------x
Inner join selects the rows that satisfies both the table.
Consider we need to find the teachers who are class teachers and their corresponding students. In that condition, we need to apply JOIN
or INNER JOIN
and will
Query
SELECT T.TchrId,T.TeacherName,S.StudentName
FROM #Teacher T
INNER JOIN #Student S ON T.TchrId = S.TchrId
Result
x--------------------------------------x
| TchrId | TeacherName | StudentName |
x----------|-------------|-------------x
| T1 | Mary | Vineeth |
| T1 | Mary | Unni |
x--------------------------------------x
Cross join selects the all the rows from the first table and all the rows from second table and shows as Cartesian product ie, with all possibilities
Consider we need to find all the teachers in the school and students irrespective of class teachers, we need to apply CROSS JOIN
.
Query
SELECT T.TchrId,T.TeacherName,S.StudentName
FROM #Teacher T
CROSS JOIN #Student S
Result
x--------------------------------------x
| TchrId | TeacherName | StudentName |
x----------|-------------|-------------x
| T2 | Jim | Vineeth |
| T2 | Jim | Unni |
| T1 | Mary | Vineeth |
| T1 | Mary | Unni |
x--------------------------------------x

If you are looking for a way to import all your images from the image
// Import all images in image folder
function importAll(r) {
let images = {};
r.keys().map((item, index) => { images[item.replace('./', '')] = r(item); });
return images;
}
const images = importAll(require.context('../images', false, /\.(gif|jpe?g|svg)$/));
Then:
<img src={images['image-01.jpg']}/>
You can find the original thread here: Dynamically import images from a directory using webpack
If you are using com.google.android.gms:play-services-maps:16.0.0

This is the first post on google so I thought I'd post different ways that are available and how they compare. Unfortunately I can't figure out how to create a table here, so it's an image. The code for each is below the image using fully qualified names.

C# 6.0 Edit:
With C# 6.0 we can now have a succinct, cast-free version of the orignal method:
string s = myObj?.ToString() ?? "";
Or even using interpolation:
string s = $"{myObj}";
Original Answer:
string s = (myObj ?? String.Empty).ToString();
or
string s = (myObjc ?? "").ToString()
to be even more concise.
Unfortunately, as has been pointed out you'll often need a cast on either side to make this work with non String or Object types:
string s = (myObjc ?? (Object)"").ToString()
string s = ((Object)myObjc ?? "").ToString()
Therefore, while it maybe appears elegant, the cast is almost always necessary and is not that succinct in practice.
As suggested elsewhere, I recommend maybe using an extension method to make this cleaner:
public static string ToStringNullSafe(this object value)
{
return (value ?? string.Empty).ToString();
}
If the form is using redirects, authentication, cookies, SSL (https), or anything else other than a totally open script expecting POST variables, you are going to start gnashing your teeth really quick. Take a look at Snoopy, which does exactly what you have in mind while removing the need to set up a lot of the overhead.
You need to parse the string you are sending from javascript object to the JSON object
var json=$.parseJSON(data);
The low-level way would be to access the matrix data directly. In an RGB image (which I believe OpenCV typically stores as BGR), and assuming your cv::Mat variable is called frame
, you could get the blue value at location (x
, y
) (from the top left) this way:
frame.data[frame.channels()*(frame.cols*y + x)];
Likewise, to get B, G, and R:
uchar b = frame.data[frame.channels()*(frame.cols*y + x) + 0];
uchar g = frame.data[frame.channels()*(frame.cols*y + x) + 1];
uchar r = frame.data[frame.channels()*(frame.cols*y + x) + 2];
Note that this code assumes the stride is equal to the width of the image.
You need to add runat="server"
and and to assign an ID for it, then specify the absolute path like this:
<script type="text/javascript" runat="server" id="myID" src="~/js/jquery.jqGrid.js"></script>]
From the codebehind, you can change the src programatically using the ID.
Don't use GridLayout for something it wasn't meant to do. It sounds to me like GridBagLayout would be a better fit for you, either that or MigLayout (though you'll have to download that first since it's not part of standard Java). Either that or combine layout managers such as BoxLayout for the lines and GridLayout to hold all the rows.
For example, using GridBagLayout:
import java.awt.*;
import javax.swing.*;
public class LayoutEg1 extends JPanel{
private static final int ROWS = 10;
public LayoutEg1() {
setLayout(new GridBagLayout());
for (int i = 0; i < ROWS; i++) {
GridBagConstraints gbc = makeGbc(0, i);
JLabel label = new JLabel("Row Label " + (i + 1));
add(label, gbc);
JPanel panel = new JPanel();
panel.add(new JCheckBox("check box"));
panel.add(new JTextField(10));
panel.add(new JButton("Button"));
panel.setBorder(BorderFactory.createEtchedBorder());
gbc = makeGbc(1, i);
add(panel, gbc);
}
}
private GridBagConstraints makeGbc(int x, int y) {
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridwidth = 1;
gbc.gridheight = 1;
gbc.gridx = x;
gbc.gridy = y;
gbc.weightx = x;
gbc.weighty = 1.0;
gbc.insets = new Insets(5, 5, 5, 5);
gbc.anchor = (x == 0) ? GridBagConstraints.LINE_START : GridBagConstraints.LINE_END;
gbc.fill = GridBagConstraints.HORIZONTAL;
return gbc;
}
private static void createAndShowUI() {
JFrame frame = new JFrame("Layout Eg1");
frame.getContentPane().add(new LayoutEg1());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
public static void main(String[] args) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
createAndShowUI();
}
});
}
}
Currently with swift 5 the easiest way to check if the player is playing or paused is to check the .timeControlStatus variable.

The issue solved after renaming the xml file name to log4j2.xml
When you use GROUP BY
, the resulting rows will be usually less then incoming rows.
But, when you use PARTITION BY
, the resulting row count should be the same as incoming.
Flexible Box Layout Module - 8.1. Aligning with auto margins
Auto margins on flex items have an effect very similar to auto margins in block flow:
During calculations of flex bases and flexible lengths, auto margins are treated as 0.
Prior to alignment via
justify-content
andalign-self
, any positive free space is distributed to auto margins in that dimension.
Therefore you could use margin-top: auto
to distribute the space between the other elements and the last element.
This will position the last element at the bottom.
p:last-of-type {
margin-top: auto;
}
.container {
display: flex;
flex-direction: column;
border: 1px solid #000;
min-height: 200px;
width: 100px;
}
p {
height: 30px;
background-color: blue;
margin: 5px;
}
p:last-of-type {
margin-top: auto;
}
_x000D_
<div class="container">
<p></p>
<p></p>
<p></p>
</div>
_x000D_
Likewise, you can also use margin-left: auto
or margin-right: auto
for the same alignment horizontally.
p:last-of-type {
margin-left: auto;
}
.container {
display: flex;
width: 100%;
border: 1px solid #000;
}
p {
height: 50px;
width: 50px;
background-color: blue;
margin: 5px;
}
p:last-of-type {
margin-left: auto;
}
_x000D_
<div class="container">
<p></p>
<p></p>
<p></p>
<p></p>
</div>
_x000D_
I know this is an old question, but it might be worth mentioning that you can create your own configurations outside of DEBUG and RELEASE, such as TEST or UAT.
If then on the Build tab of the project properties page you then set the "Conditional compilation symbols" to TEST (for instance) you can then use a construct such as
#if (DEBUG || TEST )
//Code that will not be executed in RELEASE or UAT
#endif
You can use this construct for specific reason such as different clients if you have the need, or even entire Web Methods for instance. We have also used this in the past where some commands have caused issues on specific hardware, so we have a configuration for an app when deployed to hardware X.
I wanted the changes in Git to be shown as moves/renames instead of delete & adds. So I did a combo of the above and this post.
mkdir subdirectory
git mv -k ./* ./subdirectory
# check to make sure everything moved (see below)
git commit
And adjust the paths of the projects and of the assemblies from the nuget Pkg's in the sln file via a text editor.
My workaround is to get the current title of the actionbar in the Fragment before setting it to the new title. This way, once the Fragment is popped, I can change back to that title.
@Override
public void onResume() {
super.onResume();
// Get/Backup current title
mTitle = ((ActionBarActivity) getActivity()).getSupportActionBar()
.getTitle();
// Set new title
((ActionBarActivity) getActivity()).getSupportActionBar()
.setTitle(R.string.this_fragment_title);
}
@Override
public void onDestroy() {
// Set title back
((ActionBarActivity) getActivity()).getSupportActionBar()
.setTitle(mTitle);
super.onDestroy();
}
This test shows that the string in VBA can be at least 10^8 characters long. But if you change it to 10^9 you will fail.
Sub TestForStringLengthVBA()
Dim text As String
text = Space(10 ^ 8) & "Hello world"
Debug.Print Len(text)
text = Right(text, 5)
Debug.Print text
End Sub
So do not be mislead by Intermediate window editor or MsgBox output.
I developed an inelegant solution. Consider that we have the X axis and also a list of labels for each point in X.
Example:import matplotlib.pyplot as plt
x = [0,1,2,3,4,5]
y = [10,20,15,18,7,19]
xlabels = ['jan','feb','mar','apr','may','jun']
Let's say that I want to show ticks labels only for 'feb' and 'jun'
xlabelsnew = []
for i in xlabels:
if i not in ['feb','jun']:
i = ' '
xlabelsnew.append(i)
else:
xlabelsnew.append(i)
Good, now we have a fake list of labels. First, we plotted the original version.
plt.plot(x,y)
plt.xticks(range(0,len(x)),xlabels,rotation=45)
plt.show()
Now, the modified version.
plt.plot(x,y)
plt.xticks(range(0,len(x)),xlabelsnew,rotation=45)
plt.show()
After the blog post How Can I Use Windows PowerShell to Delete All the .TMP Files on a Drive?, you can use something like this to delete all .tmp for example from a folder and all subfolders in PowerShell:
get-childitem [your path/ or leave empty for current path] -include
*.tmp -recurse | foreach ($_) {remove-item $_.fullname}
Use below code to convert String Date to Epoc Timestamp. Note : - Your input Date format should match with SimpleDateFormat.
String inputDateInString= "8/15/2017 12:00:00 AM";
SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyy hh:mm:ss");
Date parsedDate = dateFormat.parse("inputDateInString");
Timestamp timestamp = new java.sql.Timestamp(parsedDate.getTime());
System.out.println("Timestamp "+ timestamp.getTime());
Explanation from the Preshing on Programming blog:
It’s handy when you have two related operations which you’d like to execute as a pair, with a block of code in between. The classic example is opening a file, manipulating the file, then closing it:
with open('output.txt', 'w') as f: f.write('Hi there!')
The above with statement will automatically close the file after the nested block of code. (Continue reading to see exactly how the close occurs.) The advantage of using a with statement is that it is guaranteed to close the file no matter how the nested block exits. If an exception occurs before the end of the block, it will close the file before the exception is caught by an outer exception handler. If the nested block were to contain a return statement, or a continue or break statement, the with statement would automatically close the file in those cases, too.
No need to cede.
just select pane ,right click then select Fit to parent.
It will automatically resize pane to anchor pane size.
To convert month number to month name, try the below
declare @month smallint = 1
select DateName(mm,DATEADD(mm,@month - 1,0))
Hey, this one is kind of ugly but it's one line only:

From Tomcat documentation, For blocking I/O (BIO), the default value of maxConnections
is the value of maxThreads
unless Executor (thread pool) is used in which case, the value of 'maxThreads' from Executor will be used instead. For Non-blocking IO, it doesn't seem to be dependent on maxThreads
.
std::list
doesn't provide any function to get element given an index. You may try to get it by writing some code, which I wouldn't recommend, because that would be inefficient if you frequently need to do so.
What you need is : std::vector
. Use it as:
std::vector<Object> objects;
objects.push_back(myObject);
Object const & x = objects[0]; //index isn't checked
Object const & y = objects.at(0); //index is checked
That 2GB
limit you see is the total memory of the VM in which docker runs.
If you are using docker-for-windows or docker-for-mac you can easily increase it from the Whale icon in the task bar, then go to Preferences -> Advanced:
But if you are using VirtualBox behind, open VirtualBox, Select and configure the docker-machine assigned memory.
See this for Mac:
https://docs.docker.com/docker-for-mac/#memory
MEMORY By default, Docker for Mac is set to use 2 GB runtime memory, allocated from the total available memory on your Mac. You can increase the RAM on the app to get faster performance by setting this number higher (for example to 3) or lower (to 1) if you want Docker for Mac to use less memory.
For Windows:

In order to make dir more useful (in the case a local file with no path is specified as input) I did the following:
# Substring from 0 thru pos of filename
dir="${fullpath:0:${#fullpath} - ${#filename}}"
if [[ -z "$dir" ]]; then
dir="./"
fi
This allows you to do something useful like add a suffix to the input file basename as:
outfile=${dir}${base}_suffix.${ext}
testcase: foo.bar
dir: "./"
base: "foo"
ext: "bar"
outfile: "./foo_suffix.bar"
testcase: /home/me/foo.bar
dir: "/home/me/"
base: "foo"
ext: "bar"
outfile: "/home/me/foo_suffix.bar"
In Android Studio open:
File > Project Structure
and check if JDK location points to your JDK 1.8 directory.
Note: you can use compileSdkVersion 24
.
It works trust me. For this to work first download latest JDK from Oracle.
GZip Compression can be enabled directly through IIS.
First, open up IIS,
go to the website you are hoping to tweak and hit the Compression page. If Gzip is not installed, you will see something like the following:
“The dynamic content compression module is not installed.” We should fix this. So we go to the “Turn Windows features on or off” and select “Dynamic Content Compression” and click the OK button.
Now if we go back to IIS, we should see that the compression page has changed. At this point we need to make sure the dynamic compression checkbox is checked and we’re good to go. Compression is enabled and our dynamic content will be Gzipped.
Testing - Check if GZIP Compression is Enabled
To test whether compression is working or not, use the developer tools in Chrome or Firebug for Firefox and ensure the HTTP response header is set:
Content-Encoding: gzip
This is the correct way:
You should declare the length of the array after "="
Veicle[] cars = new Veicle[N];
Using Console.WriteLine( "Test" );
is able to write log messages to the Output Window (View Menu --> Output) in Visual Studio for a Windows Forms/WPF project.
However, I encountered a case where it was not working and only System.Diagnostics.Debug.WriteLine( "Test" );
was working. I restarted Visual Studio and Console.WriteLine()
started working again. Seems to be a Visual Studio bug.
No, but they're fakeable using proxies and reflection:
public static class TestClass {
public String knockKnock() {
return "who's there?";
}
}
private final TestClass testInstance = new TestClass();
@Test public void
can_delegate_a_single_method_interface_to_an_instance() throws Exception {
Delegator<TestClass, Callable<String>> knockKnockDelegator = Delegator.ofMethod("knockKnock")
.of(TestClass.class)
.to(Callable.class);
Callable<String> callable = knockKnockDelegator.delegateTo(testInstance);
assertThat(callable.call(), is("who's there?"));
}
The nice thing about this idiom is that you can verify that the delegated-to method exists, and has the required signature, at the point where you create the delegator (although not at compile-time, unfortunately, although a FindBugs plug-in might help here), then use it safely to delegate to various instances.
See the karg code on github for more tests and implementation.
I was trying to format the date string received from a JSON response e.g. 2016-03-09T04:50:00-0800 to yyyy-MM-dd. So here's what I tried and it worked and helped me assign the formatted date string a calendar widget.
String DATE_FORMAT_I = "yyyy-MM-dd'T'HH:mm:ss";
String DATE_FORMAT_O = "yyyy-MM-dd";
SimpleDateFormat formatInput = new SimpleDateFormat(DATE_FORMAT_I);
SimpleDateFormat formatOutput = new SimpleDateFormat(DATE_FORMAT_O);
Date date = formatInput.parse(member.getString("date"));
String dateString = formatOutput.format(date);
This worked. Thanks.
I had a similar issue that was resolved by unchecking the option in java advanced security for "Use SSL 2.0 compatible ClientHello format.
Try ejecting the config files, by running:
npm run eject
then you'll find a config folder created in your project. You will find your webpack config files init.
The particular exception message is telling you that the mentioned class is missing in the classpath. As the org.apache.commons.io

And indeed, Commons FileUpload has Commons IO as a dependency. You need to download and drop commons-io.jar

I really like the reflections library for doing this.
It provides a lot of different types of scanners (getTypesAnnotatedWith

extension Date {
func toString(template: String) -> String {
let formatter = DateFormatter()
formatter.dateFormat = DateFormatter.dateFormat(fromTemplate: template, options: 0, locale: NSLocale.current)

let now = Date()
let nowStr0 = now.toString(template: "EEEEdMMM") // Tuesday, May 9
let nowStr1 = now.toString(template: "yyyy-MM-dd") // 2017-05-09

Play with template to match your needs. Examples and doc here to help you build the template you need.
You may want to cache your DateFormatter
if you plan to use it in TableView
for instance.
To give an idea, looping over 1000 dates took me 0.5 sec using the above toString(template: String)
function, compared to 0.05 sec using myFormatter.string(from: Date)
.
To Delete the duplicate record in a table.
delete from job s
where rowid < any
(select rowid from job k
where s.site_id = k.site_id and
s.title = k.title and
s.company = k.company);
or
delete from job s
where rowid not in
(select max(rowid) from job k
where s.site_id = k.site_id and
s.title = k.title and
s.company = k.company);
grep -Fxvf file1 file2
What the flags mean:
-F, --fixed-strings
Interpret PATTERN as a list of fixed strings, separated by newlines, any of which is to be matched.
-x, --line-regexp
Select only those matches that exactly match the whole line.
-v, --invert-match
Invert the sense of matching, to select non-matching lines.
-f FILE, --file=FILE
Obtain patterns from FILE, one per line. The empty file contains zero patterns, and therefore matches nothing.
double minutes = varTime.TotalMinutes;
int minutesRounded = (int)Math.Round(varTime.TotalMinutes);
TimeSpan.TotalMinutes: The total number of minutes represented by this instance.
Yo could also set labels = FALSE
inside axis(...)
and print the labels in a separate command with Text. With this option you can rotate the text the text in case you need it
lablist<-as.vector(c(1:10))
axis(1, at=seq(1, 10, by=1), labels = FALSE)
text(seq(1, 10, by=1), par("usr")[3] - 0.2, labels = lablist, srt = 45, pos = 1, xpd = TRUE)
Detailed explanation here
You can not insert an array directly to MySQL as MySQL doesn't understand PHP data types. MySQL only understands SQL. So to insert an array into a MySQL database you have to convert it to a SQL statement. This can be done manually or by a library. The output should be an INSERT
statement.
Update for PHP7
Since PHP 5.5
mysql_real_escape_string
has been deprecated and as of PHP7 it has been removed. See: php.net's documentation on the new procedure.
Original answer:
Here is a standard MySQL insert statement.
INSERT INTO TABLE1(COLUMN1, COLUMN2, ....) VALUES (VALUE1, VALUE2..)
If you have a table with name fbdata
with the columns which are presented in the keys of your array you can insert with this small snippet. Here is how your array is converted to this statement.
$columns = implode(", ",array_keys($insData));
$escaped_values = array_map('mysql_real_escape_string', array_values($insData));
$values = implode(", ", $escaped_values);
$sql = "INSERT INTO `fbdata`($columns) VALUES ($values)";
to refresh the form you need to type - me.refresh in the button event on click
replace()
method will work for this. Here is the code that will help to remove character from string. lets say
j_word = 'Stringtoremove'
word = 'String'
for letter in word:
if j_word.find(letter) == -1:
continue
else:
# remove matched character
j_word = j_word.replace(letter, '', 1)
#Output
j_word = "toremove"
Here I use the sample
method to generate 10 random numbers between 0 and 100.
Note: I'm using Python 3's range
function (not xrange
).
import random
print(random.sample(range(0, 100), 10))
The output is placed into a list:
[11, 72, 64, 65, 16, 94, 29, 79, 76, 27]

You can use django-overextends, which provides circular template inheritance for Django.
It comes from the Mezzanine CMS, from where Stephen extracted it into a standalone Django extension.
More infos you find in "Overriding vs Extending Templates" (http:/mezzanine.jupo.org/docs/content-architecture.html#overriding-vs-extending-templates) inside the Mezzanine docs.
For deeper insides look at Stephens Blog "Circular Template Inheritance for Django" (http:/blog.jupo.org/2012/05/17/circular-template-inheritance-for-django).
And in Google Groups the discussion (https:/groups.google.com/forum/#!topic/mezzanine-users/sUydcf_IZkQ) which started the development of this feature.

What follows is an explanation for what is going on, scroll to bottom for code demos.
Passing parameter suppress=True
to function set_printoptions
works only for numbers that fit in the default 8 character space allotted to it, like this:
import numpy as np
np.set_printoptions(suppress=True) #prevent numpy exponential
#notation on print, default False
# tiny med large
a = np.array([1.01e-5, 22, 1.2345678e7]) #notice how index 2 is 8
#digits wide
print(a) #prints [ 0.0000101 22. 12345678. ]
However if you pass in a number greater than 8 characters wide, exponential notation is imposed again, like this:
np.set_printoptions(suppress=True)
a = np.array([1.01e-5, 22, 1.2345678e10]) #notice how index 2 is 10
#digits wide, too wide!
#exponential notation where we've told it not to!
print(a) #prints [1.01000000e-005 2.20000000e+001 1.23456780e+10]
numpy has a choice between chopping your number in half thus misrepresenting it, or forcing exponential notation, it chooses the latter.
Here comes set_printoptions(formatter=...)
to the rescue to specify options for printing and rounding. Tell set_printoptions
to just print bare a bare float:
np.set_printoptions(suppress=True,
formatter={'float_kind':'{:f}'.format})
a = np.array([1.01e-5, 22, 1.2345678e30]) #notice how index 2 is 30
#digits wide.
#Ok good, no exponential notation in the large numbers:
print(a) #prints [0.000010 22.000000 1234567799999999979944197226496.000000]
We've force-suppressed the exponential notation, but it is not rounded or justified, so specify extra formatting options:
np.set_printoptions(suppress=True,
formatter={'float_kind':'{:0.2f}'.format}) #float, 2 units
#precision right, 0 on left
a = np.array([1.01e-5, 22, 1.2345678e30]) #notice how index 2 is 30
#digits wide
print(a) #prints [0.00 22.00 1234567799999999979944197226496.00]
The drawback for force-suppressing all exponential notion in ndarrays is that if your ndarray gets a huge float value near infinity in it, and you print it, you're going to get blasted in the face with a page full of numbers.

and very small e-x
ranges.
This sounds more like you want a tooltip for the link selected. There are many jQuery tooltips, try out jQuery qTip. It has a lot of options and is easy to change the styles.
Otherwise if you want to do this yourself you can use the jQuery .position()
. More info about .position()
is on http://api.jquery.com/position/
$("#element").position();
will return the current position of an element relative to the offset parent.
There is also the jQuery .offset(); which will return the position relative to the document.
For me, the only way on SQL 2008 R2 was this :
