In your pom.xml file inside that <java.version> write "8" instead write "11" ,and RECOMPILE your pom.xml file And tadaaaaaa it works !

In short:

• OpenJDK has multiple meanings and can refer to:
  • free and open source implementation of the Java Platform, Standard Edition (Java SE)
  • open source repository — the Java source code aka OpenJDK project
  • prebuilt OpenJDK binaries maintained by Oracle
  • prebuilt OpenJDK binaries maintained by the OpenJDK community
• AdoptOpenJDK — prebuilt OpenJDK binaries maintained by community (open source licensed)

Explanation:

Prebuilt OpenJDK (or distribution) — binaries, built from http://hg.openjdk.java.net/, provided as an archive or installer, offered for various platforms, with a possible support contract.

OpenJDK, the source repository (also called OpenJDK project) - is a Mercurial-based open source repository, hosted at http://hg.openjdk.java.net. The Java source code. The vast majority of Java features (from the VM and the core libraries to the compiler) are based solely on this source repository. Oracle have an alternate fork of this.

OpenJDK, the distribution (see the list of providers below) - is free as in beer and kind of free as in speech, but, you do not get to call Oracle if you have problems with it. There is no support contract. Furthermore, Oracle will only release updates to any OpenJDK (the distribution) version if that release is the most recent Java release, including LTS (long-term support) releases. The day Oracle releases OpenJDK (the distribution) version 12.0, even if there's a security issue with OpenJDK (the distribution) version 11.0, Oracle will not release an update for 11.0. Maintained solely by Oracle.

Some OpenJDK projects - such as OpenJDK 8 and OpenJDK 11 - are maintained by the OpenJDK community and provide releases for some OpenJDK versions for some platforms. The community members have taken responsibility for releasing fixes for security vulnerabilities in these OpenJDK versions.

AdoptOpenJDK, the distribution is very similar to Oracle's OpenJDK distribution (in that it is free, and it is a build produced by compiling the sources from the OpenJDK source repository). AdoptOpenJDK as an entity will not be backporting patches, i.e. there won't be an AdoptOpenJDK 'fork/version' that is materially different from upstream (except for some build script patches for things like Win32 support). Meaning, if members of the community (Oracle or others, but not AdoptOpenJDK as an entity) backport security fixes to updates of OpenJDK LTS versions, then AdoptOpenJDK will provide builds for those. Maintained by OpenJDK community.

OracleJDK - is yet another distribution. Starting with JDK12 there will be no free version of OracleJDK. Oracle's JDK distribution offering is intended for commercial support. You pay for this, but then you get to rely on Oracle for support. Unlike Oracle's OpenJDK offering, OracleJDK comes with longer support for LTS versions. As a developer you can get a free license for personal/development use only of this particular JDK, but that's mostly a red herring, as 'just the binary' is basically the same as the OpenJDK binary. I guess it means you can download security-patched versions of LTS JDKs from Oracle's websites as long as you promise not to use them commercially.

Note. It may be best to call the OpenJDK builds by Oracle the "Oracle OpenJDK builds".

Donald Smith, Java product manager at Oracle writes:

Ideally, we would simply refer to all Oracle JDK builds as the "Oracle JDK", either under the GPL or the commercial license, depending on your situation. However, for historical reasons, while the small remaining differences exist, we will refer to them separately as Oracle’s OpenJDK builds and the Oracle JDK.

_{Free Builds from Source - the distribution source code is publicly available and one can assemble its own build}

_{Free Binary Distributions - the distribution binaries are publicly available for download and usage}

_{Extended Updates - aka LTS (long-term support) - Public Updates beyond the 6-month release lifecycle}

_{Commercial Support - some providers offer extended updates and customer support to paying customers, e.g. Oracle JDK (support details)}

_{Permissive License - the distribution license is non-protective, e.g. Apache 2.0}

Which Java Distribution Should I Use?

In the Sun/Oracle days, it was usually Sun/Oracle producing the proprietary downstream JDK distributions based on OpenJDK sources. Recently, Oracle had decided to do their own proprietary builds only with the commercial support attached. They graciously publish the OpenJDK builds as well on their https://jdk.java.net/ site.

What is happening starting JDK 11 is the shift from single-vendor (Oracle) mindset to the mindset where you select a provider that gives you a distribution for the product, under the conditions you like: platforms they build for, frequency and promptness of releases, how support is structured, etc. If you don't trust any of existing vendors, you can even build OpenJDK yourself.

Each build of OpenJDK is usually made from the same original upstream source repository (OpenJDK “the project”). However each build is quite unique - $free or commercial, branded or unbranded, pure or bundled (e.g., BellSoft Liberica JDK offers bundled JavaFX, which was removed from Oracle builds starting JDK 11).

If no environment (e.g., Linux) and/or license requirement defines specific distribution and if you want the most standard JDK build, then probably the best option is to use OpenJDK by Oracle or AdoptOpenJDK.

Java Is Still Free by Java Champions community (published on September 17, 2018)

Java is Still Free 2.0.0 by Java Champions community (published on March 3, 2019)

Aleksey Shipilev about JDK updates interview by Opsian (published on June 27, 2019)

For users on mac, I solved an issue similar to this by modifying my zshrc file and adding the following (although your java_home might be configured differently) :

export JAVA_HOME=$(/usr/libexec/java_home)
export ANDROID_HOME=/Users/YOURUSER/Library/Android/sdk
export PATH=$PATH:/Users/YOURUSER/Library/Android/sdk/tools
export PATH=$PATH:%ANDROID_HOME%\tools
export PATH=$PATH:/Users/YOURUSER/Library/Android/sdk

The simplest way to get an input box is with the Read-Host cmdlet and -AsSecureString parameter.

$us = Read-Host 'Enter Your User Name:' -AsSecureString
$pw = Read-Host 'Enter Your Password:' -AsSecureString

This is especially useful if you are gathering login info like my example above. If you prefer to keep the variables obfuscated as SecureString objects you can convert the variables on the fly like this:

[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))
[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pw))

If the info does not need to be secure at all you can convert it to plain text:

$user = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))

Read-Host and -AsSecureString appear to have been included in all PowerShell versions (1-6) but I do not have PowerShell 1 or 2 to ensure the commands work identically. https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/read-host?view=powershell-3.0

I ran into the exact same problem under identical circumstances. I don't have the tnsnames.ora file, and I wanted to use SQL*Plus with Easy Connection Identifier format in command line. I solved this problem as follows.

The SQL*Plus® User's Guide and Reference gives an example:

sqlplus hr@\"sales-server:1521/sales.us.acme.com\"

Pay attention to two important points:

1. The connection identifier is quoted. You have two options:
   1. You can use SQL*Plus CONNECT command and simply pass quoted string.
   2. If you want to specify connection parameters on the command line then you must add backslashes as shields before quotes. It instructs the bash to pass quotes into SQL*Plus.
2. The service name must be specified in FQDN-form as it configured by your DBA.

I found these good questions to detect service name via existing connection: 1, 2. Try this query for example:

SELECT value FROM V$SYSTEM_PARAMETER WHERE UPPER(name) = 'SERVICE_NAMES'

The simple answer for this one is that you have an undeclared (null) variable. In this case it is $md5. From the comment you put this needed to be declared elsewhere in your code

$md5 = new-object -TypeName System.Security.Cryptography.MD5CryptoServiceProvider

The error was because you are trying to execute a method that does not exist.

PS C:\Users\Matt> $md5 | gm

ComputeHash                Method     byte[] ComputeHash(System.IO.Stream inputStream), byte[] ComputeHash(byte[] buffer), byte[] ComputeHash(byte[] buffer, int offset, ...

The .ComputeHash() of $md5.ComputeHash() was the null valued expression. Typing in gibberish would create the same effect.

PS C:\Users\Matt> $bagel.MakeMeABagel()
You cannot call a method on a null-valued expression.

PowerShell by default allows this to happen as defined its StrictMode

When Set-StrictMode is off, uninitialized variables (Version 1) are assumed to have a value of 0 (zero) or $Null, depending on type. References to non-existent properties return $Null, and the results of function syntax that is not valid vary with the error. Unnamed variables are not permitted.

You can have many java versions in your system.

I think you should add the java 8 in yours JREs installed or edit.

Take a look my screen:

If you click in edit (check your java 8 path):

You can just do that too, it seems to work well too. sc create "Servicename" binPath= "Path\To\your\App.exe" DisplayName= "My Custom Service"

You can open the registry and add a string named Description in your service's registry key to add a little more descriptive information about it. It will be shown in services.msc.

You first have to 'dot' source the script, so for you :

. .\Get-NetworkStatistics.ps1

The first 'dot' asks PowerShell to load the script file into your PowerShell environment, not to start it. You should also use set-ExecutionPolicy Unrestricted or set-ExecutionPolicy AllSigned see(the Execution Policy instructions).

I've seen occasional problems with Eclipse forgetting that built-in classes (including Object and String) exist. The way I've resolved them is to:

• On the Project menu, turn off "Build Automatically"
• Quit and restart Eclipse
• On the Project menu, choose "Clean…" and clean all projects
• Turn "Build Automatically" back on and let it rebuild everything.

This seems to make Eclipse forget whatever incorrect cached information it had about the available classes.

You may try this one,

declare @Number INT = 5                            
print 'There are ' + CONVERT(VARCHAR, @Number) + ' alias combinations did not match a record'

The MOD keyword only exists in the DAX language (tabular dimensional queries), not TSQL

Use % instead.

Ref: Modulo

Because you are choosing jre dir. and not JDK dir. JDK dir. is for instance (depending on update and whether it's 64 bit or 32 bit): C:\Program Files (x86)\Java\jdk1.7.0_45 In my case it's 32 bit JDK 1.7 update 45

The effect you want is to treat the NULL as the largest possible date then replace it with NULL again upon completion:

SELECT RecordId, MIN(StartDate), NULLIF(MAX(COALESCE(EndDate,'9999-12-31')),'9999-12-31') 
  FROM tmp GROUP BY RecordId

Per your fiddle this will return the exact results you specify under all conditions.

Check out the ReadKey() method on the System.Console .NET class. I think that will do what you're looking for.

http://msdn.microsoft.com/en-us/library/system.console.readkey(v=vs.110).aspx

Example:

Write-Host -Object ('The key that was pressed was: {0}' -f [System.Console]::ReadKey().Key.ToString());

Where is this info kept ("this connection is between computer A and server F")?

A TCP connection is recognized by source IP and port and destination IP and port. Your OS, all intermediate session-aware devices and the server's OS will recognize the connection by this.

HTTP works with request-response: client connects to server, performs a request and gets a response. Without keep-alive, the connection to an HTTP server is closed after each response. With HTTP keep-alive you keep the underlying TCP connection open until certain criteria are met.

This allows for multiple request-response pairs over a single TCP connection, eliminating some of TCP's relatively slow connection startup.

When The IIS (F) sends keep alive header (or user sends keep-alive) , does it mean that (E,C,B) save a connection

No. Routers don't need to remember sessions. In fact, multiple TCP packets belonging to same TCP session need not all go through same routers - that is for TCP to manage. Routers just choose the best IP path and forward packets. Keep-alive is only for client, server and any other intermediate session-aware devices.

which is only for my session ?

Does it mean that no one else can use that connection

That is the intention of TCP connections: it is an end-to-end connection intended for only those two parties.

If so - does it mean that keep alive-header - reduce the number of overlapped connection users ?

Define "overlapped connections". See HTTP persistent connection for some advantages and disadvantages, such as:

• Lower CPU and memory usage (because fewer connections are open simultaneously).
• Enables HTTP pipelining of requests and responses.
• Reduced network congestion (fewer TCP connections).
• Reduced latency in subsequent requests (no handshaking).

if so , for how long does the connection is saved to me ? (in other words , if I set keep alive- "keep" till when?)

An typical keep-alive response looks like this:

Keep-Alive: timeout=15, max=100

See Hypertext Transfer Protocol (HTTP) Keep-Alive Header for example (a draft for HTTP/2 where the keep-alive header is explained in greater detail than both 2616 and 2086):

• A host sets the value of the timeout parameter to the time that the host will allows an idle connection to remain open before it is closed. A connection is idle if no data is sent or received by a host.

• The max parameter indicates the maximum number of requests that a client will make, or that a server will allow to be made on the persistent connection. Once the specified number of requests and responses have been sent, the host that included the parameter could close the connection.

However, the server is free to close the connection after an arbitrary time or number of requests (just as long as it returns the response to the current request). How this is implemented depends on your HTTP server.

I ran into this same problem when I wanted to enable SSL to a project hosted on IIS 8. Finally the tool I used was OpenSSL, after many days fighting with makecert commands.The certificate is generated in Debian, but I could import it seamlessly into IIS 7 and 8.

Download the OpenSSL compatible with your OS and this configuration file. Set the configuration file as default configuration of OpenSSL.

First we will generate the private key and certificate of Certification Authority (CA). This certificate is to sign the certificate request (CSR).

You must complete all fields that are required in this process.

1. openssl req -new -x509 -days 3650 -extensions v3_ca -keyout root-cakey.pem -out root-cacert.pem -newkey rsa:4096

You can create a configuration file with default settings like this: Now we will generate the certificate request, which is the file that is sent to the Certification Authorities.

The Common Name must be set the domain of your site, for example: public.organization.com.

2. openssl req -new -nodes -out server-csr.pem -keyout server-key.pem -newkey rsa:4096

Now the certificate request is signed with the generated CA certificate.

3. openssl x509 -req -days 365 -CA root-cacert.pem -CAkey root-cakey.pem -CAcreateserial -in server-csr.pem -out server-cert.pem

The generated certificate must be exported to a .pfx file that can be imported into the IIS.

4. openssl pkcs12 -export -out server-cert.pfx -inkey server-key.pem -in server-cert.pem -certfile root-cacert.pem -name "Self Signed Server Certificate"

In this step we will import the certificate CA.

5. In your server must import the CA certificate to the Trusted Root Certification Authorities, for IIS can trust the certificate to be imported. Remember that the certificate to be imported into the IIS, has been signed with the certificate of the CA.

   • Open Command Prompt and type mmc.
   • Click on File.
   • Select Add/Remove Snap in....
   • Double click on Certificates.
   • Select Computer Account and Next ->.
   • Select Local Computer and Finish.
   • Ok.
   • Go to Certificates -> Trusted Root Certification Authorities -> Certificates, rigth click on Certificates and select All Tasks -> Import ...

• Select Next -> Browse ...
• You must select All Files to browse the location of root-cacert.pem file.
• Click on Next and select Place all certificates in the following store: Trusted Root Certification Authorities.
• Click on Next and Finish.

With this step, the IIS trust on the authenticity of our certificate.

6. In our last step we will import the certificate to IIS and add the binding site.

   • Open Internet Information Services (IIS) Manager or type inetmgr on command prompt and go to Server Certificates.
   • Click on Import....
   • Set the path of .pfx file, the passphrase and Select certificate store on Web Hosting.

• Click on OK.

• Now go to your site on IIS Manager and select Bindings... and Add a new binding.

• Select https as the type of binding and you should be able to see the imported certificate.

• Click on OK and all is done.

use value instead of query (must specify index of node to return in the XQuery as well as passing the sql data type to return as the second parameter):

select
    xt.Id
    , x.m.value( '@id[1]', 'varchar(max)' ) MetricId
from
    XmlTest xt
    cross apply xt.XmlData.nodes( '/Sqm/Metrics/Metric' ) x(m)

You may also try standard sql un-pivoting method by using a sequence of logic with the following code.. The following code has 3 steps:

1. create multiple copies for each row using cross join (also creating subject column in this case)
2. create column "marks" and fill in relevant values using case expression ( ex: if subject is science then pick value from science column)

3. remove any null combinations ( if exists, table expression can be fully avoided if there are strictly no null values in base table)

    select *
    from 
    (
       select name, subject,
       case subject
       when 'Maths' then maths
       when 'Science' then science
       when 'English' then english
       end as Marks
   from studentmarks
   Cross Join (values('Maths'),('Science'),('English')) AS Subjct(Subject)
   )as D
   where marks is not null;
   

-Contains is actually a collection operator. It is true if the collection contains the object. It is not limited to strings.

-match and -imatch are regular expression string matchers, and set automatic variables to use with captures.

-like, -ilike are SQL-like matchers.

My fix to this problem was to ensure I used the full path for all files names in the ps1 file.

First of all, you need to check that the IIS is installed in your machine, for that you can go to:

Control Panel --> Add or Remove Programs --> Windows Features --> And Check if Internet Information Services is installed with at least the 'Web Administration Tools' Enabled and The 'World Wide Web Service'

If not, check it, and Press Accept to install it.

Once that is done, you need to go to Administrative Tools in Control Panel and the IIS Will be there. Or simply run inetmgr (after Win+R).

Edit: You should have something like this:

Here are the three web pages on which we found the answer. The most difficult part was setting up static ports for SQLEXPRESS.

Provisioning a SQL Server Virtual Machine on Windows Azure. These initial instructions provided 25% of the answer.

How to Troubleshoot Connecting to the SQL Server Database Engine. Reading this carefully provided another 50% of the answer.

How to configure SQL server to listen on different ports on different IP addresses?. This enabled setting up static ports for named instances (eg SQLEXPRESS.) It took us the final 25% of the way to the answer.

you should add plug in to your local setting of firefox in your user home

 vladimir@shinsengumi ~/.mozilla/plugins $ pwd
 /home/vladimir/.mozilla/plugins 
 vladimir@shinsengumi ~/.mozilla/plugins $ ls -ltr

I guess you could use curl and wget, but since Oracle requires you to check of some checkmarks this will be painfull to emulate with the tools mentioned. You would have to download the page with the license agreement and from looking at it figure out what request is needed to get to the actual download.

Of course you could simply start a browser, but this might not qualify as 'from the command line'. So you might want to look into lynx, a text based browser.

I'd use B because that in conjunction with worker process recycling means there'd only be a delay while it's recycling. This avoids the delay normally associated with initialization in response to the first request after idle. You also get to keep the benefits of recycling.

gci "C:\WINDOWS\System32" -r -include .txt | select fullname

Oddly enough it was an Intel thing not a Microsoft thing. X86 referred to the Intel CPU series from the 8086 to the 80486. The Pentium series still use the same addressing system. The x64 refers to the I64 addressing system that Intel came out with later for the 64-bit CPUs. So Windows was just following Intel's architecture naming.

If you want to fix vbs associations type

regsvr32 vbscript.dll
regsvr32 jscript.dll
regsvr32 wshext.dll
regsvr32 wshom.ocx
regsvr32 wshcon.dll
regsvr32 scrrun.dll

Also if you can't use vbs due to management then convert your script to a vb.net program which is designed to be easy, is easy, and takes 5 minutes.

Big difference is functions and subs are both called using brackets rather than just functions.

So the compilers are installed on all computers with .NET installed.

See this article here on how to make a .NET exe. Note the sample is for a scripting host. You can't use this, you have to put your vbs code in as .NET code.

How can I convert a VBScript to an executable (EXE) file?

To complement Justus Thane's helpful answer:

• As Joey notes in a comment, PowerShell has a powerful, regex-based -split operator.

  • In its unary form (-split '...'), -split behaves like awk's default field splitting, which means that:
    • Leading and trailing whitespace is ignored.
    • Any run of whitespace (e.g., multiple adjacent spaces) is treated as a single separator.

• In PowerShell v4+ an expression-based - and therefore faster - alternative to the ForEach-Object cmdlet became available: the .ForEach() array (collection) method, as described in this blog post (alongside the .Where() method, a more powerful, expression-based alternative to Where-Object).

Here's a solution based on these features:

PS> (-split '   One      for the money   ').ForEach({ "token: [$_]" })
token: [One]
token: [for]
token: [the]
token: [money]

Note that the leading and trailing whitespace was ignored, and that the multiple spaces between One and for were treated as a single separator.

Default behaviour of PowerShell is just to dump everything that falls out of a pipeline without being picked up by another pipeline element or being assigned to a variable (or redirected) into Out-Host. What Out-Host does is obviously host-dependent.

Just letting things fall out of the pipeline is not a substitute for Write-Host which exists for the sole reason of outputting text in the host application.

If you want output, then use the Write-* cmdlets. If you want return values from a function, then just dump the objects there without any cmdlet.

Or try adding this...

$code = @"
[DllImport("kernel32.dll")]
public static extern int GetExitCodeProcess(IntPtr hProcess, out Int32 exitcode);
"@
$type = Add-Type -MemberDefinition $code -Name "Win32" -Namespace Win32 -PassThru
[Int32]$exitCode = 0
$type::GetExitCodeProcess($process.Handle, [ref]$exitCode)

By using this code, you can still let PowerShell take care of managing redirected output/error streams, which you cannot do using System.Diagnostics.Process.Start() directly.

I finally tracked this down to .NET Code Access Security. I have some internally-developed binary modules that are stored on and executed from a network share. To get .NET 2.0/PowerShell 2.0 to load them, I had added a URL rule to the Intranet code group to trust that directory:

PS> & "$Env:SystemRoot\Microsoft.NET\Framework64\v2.0.50727\caspol.exe" -machine -listgroups
Microsoft (R) .NET Framework CasPol 2.0.50727.5420

Security is ON
Execution checking is ON
Policy change prompt is ON

Note that, depending on which versions of .NET are installed and whether it's 32- or 64-bit Windows, caspol.exe can exist in the following locations, each with their own security configuration (security.config):

...I am left with the default CAS configuration and local scripts now work again. It's been a while since I've tinkered with CAS, and I'm not sure why my rule would seem to interfere with those granting FullTrust to MyComputer, but since CAS is deprecated as of .NET 4.0 (on which PowerShell 3.0 is based), I guess it's a moot point now.

Here's another option, which is less efficient but more concise. It's how I generally handle this sort of problem:

Get-ChildItem -Recurse .\targetdir -Exclude *.log |
  Where-Object { $_.FullName -notmatch '\\excludedir($|\\)' }

The \\excludedir($|\\)' expression allows you to exclude the directory and its contents at the same time.

Update: Please check the excellent answer from msorens for an edge case flaw with this approach, and a much more fleshed out solution overall.

You should uninstall all old [JREs][1] and then install the newest one... I had the same problem and now I solve it. I've:

Better install Jre 6 32 bit. It really works.

Try SQLDeveloper - there is a migration workbench there

It looks to me like Windows 8 and IIS 7 no longer provides any UI to create a user name and password for basic authentication that is NOT a windows local user account. It is clearly a superior approach to create an IIS-only user/password authentication pair, but it is not clear and easy how it is done.

Command line tools exist for this purpose. Some people create a Windows account and then remove the Log on Locally User Privilege.

Use:

Get-ADPrincipalGroupMembership username | select name | export-CSV username.csv

This pipes output of the command into a CSV file.

For offline Javadoc from zip file rather than extracting it.

Why this approach?

This is already answered which uses extracted zip data but it consumes more memory than simple zip file.

Comparison of zip file and extracted data.

jdk-6u25-fcs-bin-b04-apidocs.zip  --->  ~57 MB
after extracting this zip file  --->  ~264 MB !

So this approach saves my approx. 200 MB.

How to use apidocs.zip?

1.Open Windows -> Preferences

2.Select jre from Installed JREs then Click Edit...

3.Select all .jar files from JRE system libraries then Click Javadoc Location...

4.Browse for apidocs.zip file for Archive path and set Path within archive as shown above. That's it.

5.Put cursor on any class name or method name and hit Shift + F2

you have to cast in to array

Arrays.asList((Object[]) array)

A very convenient -- but probably not all too efficient -- solution is to use the member function GetDateTimeFormats(),

$d = Get-Date
$d.GetDateTimeFormats()

This outputs a large string-array of formatting styles for the date-value. You can then pick one of the elements of the array via the []-operator, e.g.,

PS C:\> $d.GetDateTimeFormats()[12]

If you are on PowerShell 2.0, use PowerShell.exe's -File parameter to invoke a script from another environment, like cmd.exe. For example:

Powershell.exe -File C:\my_path\yada_yada\run_import_script.ps1

Can you try the following?

psexec \\server cmd /c "echo . | powershell script.ps1"

A quick definition of the "permanent generation":

"The permanent generation is used to hold reflective data of the VM itself such as class objects and method objects. These reflective objects are allocated directly into the permanent generation, and it is sized independently from the other generations." [ref]

In other words, this is where class definitions go (and this explains why you may get the message OutOfMemoryError: PermGen space if an application loads a large number of classes and/or on redeployment).

Note that PermSize is additional to the -Xmx value set by the user on the JVM options. But MaxPermSize allows for the JVM to be able to grow the PermSize to the amount specified. Initially when the VM is loaded, the MaxPermSize will still be the default value (32mb for -client and 64mb for -server) but will not actually take up that amount until it is needed. On the other hand, if you were to set BOTH PermSize and MaxPermSize to 256mb, you would notice that the overall heap has increased by 256mb additional to the -Xmx setting.

A copy of System.Management.Automation.dll is installed when you install the windows SDK (a suitable, recent version of it, anyway). It should be in C:\Program Files\Reference Assemblies\Microsoft\WindowsPowerShell\v1.0\

Cross apply works well with an XML field as well. If you wish to select node values in combination with other fields.

For example, if you have a table containing some xml

<root>
    <subnode1>
       <some_node value="1" />
       <some_node value="2" />
       <some_node value="3" />
       <some_node value="4" />
    </subnode1>
</root>

Using the query

SELECT
       id as [xt_id]
      ,xmlfield.value('(/root/@attribute)[1]', 'varchar(50)') root_attribute_value
  ,node_attribute_value = [some_node].value('@value', 'int')
  ,lt.lt_name   
FROM dbo.table_with_xml xt
CROSS APPLY xmlfield.nodes('/root/subnode1/some_node') as g ([some_node])
LEFT OUTER JOIN dbo.lookup_table lt
ON [some_node].value('@value', 'int') = lt.lt_id

Will return a result

xt_id root_attribute_value node_attribute_value lt_name
----------------------------------------------------------------------
1     test1            1                    Benefits
1     test1            4                    FINRPTCOMPANY

I use a small set of documentation patterns:

• always documenting about thread-safety
• always documenting immutability
• javadoc with examples (like Formatter)
• @Deprecation with WHY and HOW to replace the annotated element

Look here.

Your URL is quite incorrect. Should look like this:

url="jdbc:oracle:thin:@localhost:1521:orcl"

You don't register a driver class, either. You want to download the thin driver JAR, put it in your CLASSPATH, and make your code look more like this.

UPDATE: The "14" in "ojdbc14.jar" stands for JDK 1.4. You should match your driver version with the JDK you're running. I'm betting that means JDK 5 or 6.

SELECT CONVERT(char(10), GetDate(),126)

Limiting the size of the varchar chops of the hour portion that you don't want.

In CMD, '&&' means "execute command 1, and if it succeeds, execute command 2". I have used it for things like:

build && run_tests

In PowerShell, the closest thing you can do is:

(build) -and (run_tests)

It has the same logic, but the output text from the commands is lost. Maybe it is good enough for you, though.

If you're doing this in a script, you will probably be better off separating the statements, like this:

build
if ($?) {
    run_tests
}

2019/11/27: The &&operator is now available for PowerShell 7 Preview 5+:

PS > echo "Hello!" && echo "World!"
Hello!
World!

I had issues with stefan's solution. Below is a modified version which seems to work well.

UPDATE

If you just want to know which process(es) are locking a particular DLL, you can execute and parse the output of tasklist /m YourDllName.dll. Works on Windows XP and later. See

What does this do? tasklist /m "mscor*"

The hack is recursive. It is like IE itself uses the component that is used by many other processes which want "web component". Hence in registry we add IEXPLORE.exe. In effect it is a recursive hack.

The command JG simply means: Jump if Greater. The result of the preceding instructions is stored in certain processor flags (in this it would test if ZF=0 and SF=OF) and jump instruction act according to their state.

This selector should work but will be more efficient if you replace it with your suited markup:

//*[contains(@class, 'Test')]

Or, since we know the sought element is a div:

//div[contains(@class, 'Test')]

But since this will also match cases like class="Testvalue" or class="newTest", @Tomalak's version provided in the comments is better:

//div[contains(concat(' ', @class, ' '), ' Test ')]

If you wished to be really certain that it will match correctly, you could also use the normalize-space function to clean up stray whitespace characters around the class name (as mentioned by @Terry):

//div[contains(concat(' ', normalize-space(@class), ' '), ' Test ')]

Note that in all these versions, the * should best be replaced by whatever element name you actually wish to match, unless you wish to search each and every element in the document for the given condition.

Or another typical standard in the industry is to have a Constants.java named class file containing all the constants to be used all over the project.

You can set a new variable and have it incremented by ++ (count up one) every time it runs, then I use a conditional statement to end it:

var intervalId = null;
var varCounter = 0;
var varName = function(){
     if(varCounter <= 10) {
          varCounter++;
          /* your code goes here */
     } else {
          clearInterval(intervalId);
     }
};

$(document).ready(function(){
     intervalId = setInterval(varName, 10000);
});

I hope that it helps and it is right.

My solution was

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -

echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

sudo apt-get update && sudo apt-get install yarn

From the command line:

psql -f 1.sql
psql -f 2.sql

From the psql prompt:

\i 1.sql
\i 2.sql

Note that you may need to import the files in a specific order (for example: data definition before data manipulation). If you've got bash shell (GNU/Linux, Mac OS X, Cygwin) and the files may be imported in the alphabetical order, you may use this command:

for f in *.sql ; do psql -f $f ; done

Here's the documentation of the psql application (thanks, Frank): http://www.postgresql.org/docs/current/static/app-psql.html

In General:

An example of an easy way to post XML data and get the response (as a string) would be the following function:

public string postXMLData(string destinationUrl, string requestXml)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl);
    byte[] bytes;
    bytes = System.Text.Encoding.ASCII.GetBytes(requestXml);
    request.ContentType = "text/xml; encoding='utf-8'";
    request.ContentLength = bytes.Length;
    request.Method = "POST";
    Stream requestStream = request.GetRequestStream();
    requestStream.Write(bytes, 0, bytes.Length);
    requestStream.Close();
    HttpWebResponse response;
    response = (HttpWebResponse)request.GetResponse();
    if (response.StatusCode == HttpStatusCode.OK)
    {
        Stream responseStream = response.GetResponseStream();
        string responseStr = new StreamReader(responseStream).ReadToEnd();
        return responseStr;
    }
    return null;
}

In your specific situation:

Instead of:

request.ContentType = "application/x-www-form-urlencoded";

use:

request.ContentType = "text/xml; encoding='utf-8'";

Also, remove:

string postData = "XMLData=" + Sendingxml;

And replace:

byte[] byteArray = Encoding.UTF8.GetBytes(postData);

with:

byte[] byteArray = Encoding.UTF8.GetBytes(Sendingxml.ToString());

issuing 2 command can do the trick

DBCC CHECKIDENT ('[TestTable]', RESEED,0)
DBCC CHECKIDENT ('[TestTable]', RESEED)

the first reset the identity to zero , and the next will set it to the next available value -- jacob

Just check if the field is null or not using ResultSet#getObject(). Substitute -1 with whatever null-case value you want.

int foo = resultSet.getObject("foo") != null ? resultSet.getInt("foo") : -1;

Or, if you can guarantee that you use the right DB column type so that ResultSet#getObject() really returns an Integer (and thus not Long, Short or Byte), then you can also just typecast it to an Integer.

Integer foo = (Integer) resultSet.getObject("foo");

Note that you can also use the C99 fixed-width types perfectly well in Objective-C:

#import <stdint.h>
...
int32_t x; // guaranteed to be 32 bits on any platform

The wikipedia page has a decent description of what's available in this header if you don't have a copy of the C standard (you should, though, since Objective-C is just a tiny extension of C). You may also find the headers limits.h and inttypes.h to be useful.

One workaround I had for this was to iterate over the sectors(which at the time you could do...I haven't tested that recently).

You wind up getting blocked eventually when you do it that way though, since YQL gets throttled per day.

Use the CSV API whenever possible to avoid this.

Tutorial is not really required for this. Read up on encapsulation

private String myField; //"private" means access to this is restricted

public String getMyField()
{
     //include validation, logic, logging or whatever you like here
    return this.myField;
}
public void setMyField(String value)
{
     //include more logic
     this.myField = value;
}

This an example from my code how to address a widget(button) in popupwindow

View v=LayoutInflater.from(getContext()).inflate(R.layout.popupwindow, null, false);
    final PopupWindow pw = new PopupWindow(v,500,500, true);
    final Button button = rootView.findViewById(R.id.button);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            pw.showAtLocation(rootView.findViewById(R.id.constraintLayout), Gravity.CENTER, 0, 0);


        }
    });
    final Button popup_btn=v.findViewById(R.id.popupbutton);

    popup_btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            popup_btn.setBackgroundColor(Color.RED);
        }
    });

Hope this help you

Here is a slight improvement on the this answer above taking care of both .xlsx and .xls files in the same routine, in case it helps someone!

I also add a line to choose to save with the active sheet name instead of the workbook, which is most practical for me often:

Sub ExportAsCSV()

    Dim MyFileName As String
    Dim CurrentWB As Workbook, TempWB As Workbook

    Set CurrentWB = ActiveWorkbook
    ActiveWorkbook.ActiveSheet.UsedRange.Copy

    Set TempWB = Application.Workbooks.Add(1)
    With TempWB.Sheets(1).Range("A1")
        .PasteSpecial xlPasteValues
        .PasteSpecial xlPasteFormats
    End With

    MyFileName = CurrentWB.Path & "\" & Left(CurrentWB.Name, InStrRev(CurrentWB.Name, ".") - 1) & ".csv"
    'Optionally, comment previous line and uncomment next one to save as the current sheet name
    'MyFileName = CurrentWB.Path & "\" & CurrentWB.ActiveSheet.Name & ".csv"


    Application.DisplayAlerts = False
    TempWB.SaveAs Filename:=MyFileName, FileFormat:=xlCSV, CreateBackup:=False, Local:=True
    TempWB.Close SaveChanges:=False
    Application.DisplayAlerts = True
End Sub

With Swift 1.2 (and maybe earlier) you now need to use:

let nums = [1, 6, 3, 9, 4, 6];
let numMax = nums.reduce(Int.min, combine: { max($0, $1) })

For working with Double values I used something like this:

let nums = [1.3, 6.2, 3.6, 9.7, 4.9, 6.3];
let numMax = nums.reduce(-Double.infinity, combine: { max($0, $1) })

Swift 5

In my case I needed access to the UILabel that was clicked, so you could do this inside the gesture recognizer.

let label:UILabel = gesture.view as! UILabel

The gesture.view property contains the view of what was clicked, you can simply downcast it to what you know it is.

@IBAction func tapLabel(gesture: UITapGestureRecognizer) {

        let label:UILabel = gesture.view as! UILabel

        guard let text = label.attributedText?.string else {
            return
        }

        print(text)
}

So you could do something like above for the tapLabel function and in viewDidLoad put...

<Label>.addGestureRecognizer(UITapGestureRecognizer(target:self, action: #selector(tapLabel(gesture:))))

Just replace <Label> with your actual label name

None is a singleton object (meaning there is only one None), used in many places in the language and library to represent the absence of some other value.

For example:
if d is a dictionary, d.get(k) will return d[k] if it exists, but None if d has no key k.

One thing that needs to be mentioned. You have to use the x86 version of Python 2.7. OpenCV doesn't support Python x64. I banged my head on this for a bit until I figured that out.

That said, follow the steps in Abid Rahman K's answer. And as Antimony said, you'll need to do a 'from cv2 import cv'

Following Microsoft tutorial-upgrade ASP.NET MVC 4 to ASP.NET MVC 5, http://www.asp.net/mvc/tutorials/mvc-5/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2, you can achieve that with one problem that Visual Studio 2012 will not be able to recognize your project as neither ASP.NET MVC 4 nor 5.

It will deal with it as a Web Form project. For example, options such adding a controller will not be there any more...

The accepted answer doesn't differentiate between a first run and subsequent upgrades. Just setting a boolean in shared preferences will only tell you if it is the first run after the app is first installed. Later if you want to upgrade your app and make some changes on the first run of that upgrade, you won't be able to use that boolean any more because shared preferences are saved across upgrades.

This method uses shared preferences to save the version code rather than a boolean.

import com.yourpackage.BuildConfig;
...

private void checkFirstRun() {

    final String PREFS_NAME = "MyPrefsFile";
    final String PREF_VERSION_CODE_KEY = "version_code";
    final int DOESNT_EXIST = -1;

    // Get current version code
    int currentVersionCode = BuildConfig.VERSION_CODE;

    // Get saved version code
    SharedPreferences prefs = getSharedPreferences(PREFS_NAME, MODE_PRIVATE);
    int savedVersionCode = prefs.getInt(PREF_VERSION_CODE_KEY, DOESNT_EXIST);

    // Check for first run or upgrade
    if (currentVersionCode == savedVersionCode) {

        // This is just a normal run
        return;

    } else if (savedVersionCode == DOESNT_EXIST) {

        // TODO This is a new install (or the user cleared the shared preferences)

    } else if (currentVersionCode > savedVersionCode) {

        // TODO This is an upgrade
    }

    // Update the shared preferences with the current version code
    prefs.edit().putInt(PREF_VERSION_CODE_KEY, currentVersionCode).apply();
}

You would probably call this method from onCreate in your main activity so that it is checked every time your app starts.

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        checkFirstRun();
    }

    private void checkFirstRun() {
        // ...
    }
}

If you needed to, you could adjust the code to do specific things depending on what version the user previously had installed.

Idea came from this answer. These also helpful:

• How can you get the Manifest Version number from the App's (Layout) XML variables?
• User versionName value of AndroidManifest.xml in code

If you are having trouble getting the version code, see the following Q&A:

You can do with the following command at the time of running docker

docker run [OPTIONS] --add-host example.com:127.0.0.1 <your-image-name>:<your tag>

Here I am mapping example.com to localhost 127.0.0.1 and its working.

I used pyplot's axes object to manually adjust the sizes without using GridSpec:

import matplotlib.pyplot as plt
import numpy as np
x = np.arange(0, 10, 0.2)
y = np.sin(x)

# definitions for the axes
left, width = 0.07, 0.65
bottom, height = 0.1, .8
bottom_h = left_h = left+width+0.02

rect_cones = [left, bottom, width, height]
rect_box = [left_h, bottom, 0.17, height]

fig = plt.figure()

cones = plt.axes(rect_cones)
box = plt.axes(rect_box)

cones.plot(x, y)

box.plot(y, x)

plt.show()

Change URL behavior to "Dynamic".

NSLocale* currentLocale = [NSLocale currentLocale];
[[NSDate date] descriptionWithLocale:currentLocale];  

or use

NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
// or @"yyyy-MM-dd hh:mm:ss a" if you prefer the time with AM/PM 
NSLog(@"%@",[dateFormatter stringFromDate:[NSDate date]]);

Adding to @marbel's answer (which is a great suggestion!), here's the script that worked for me on Mac OS X El Captain's Terminal, for batch conversion (since that's what the OP asked). I thought it would be trivial to do a for loop but it wasn't! (had to change the extension by string manipulation and it looks like Mac's bash is a bit different also)

for x in $(ls *.xlsx); do x1=${x%".xlsx"}; in2csv $x > $x1.csv; echo "$x1.csv done."; done

Note:

1. ${x%”.xlsx”} is bash string manipulation which clips .xlsx from the end of the string.
2. in2csv creates separate csv files (doesn’t overwrite the xlsx's).
3. The above won't work if the filenames have white spaces in them. Good to convert white spaces to underscores or something, before running the script.

Currently both deletedir() and cleanWs() do not work properly when using Jenkins kubernetes plugin, the pod workspace is deleted but the master workspace persists

it should not be a problem for persistant branches, when you have a step to clean the workspace prior to checkout scam. It will basically reuse the same workspace over and over again: but when using multibranch pipelines the master keeps the whole workspace and git directory

I believe this should be an issue with Jenkins, any enlightenment here?

Just use /\s+/ against '' as a splitter. In this case all "extra" blanks were removed. Usually this particular behaviour is required. So, in you case it will be:

my $line = "file1.gz file1.gz file3.gz";
my @abc = split(/\s+/, $line);

I've found out a nice workaround to IP blocking when scraping sites. It lets you run a Scraper indefinitely by running it from Google App Engine and redeploying it automatically when you get a 429.

Check out this article

Please set the request Content Type before you read the response stream;

 request.ContentType = "text/xml";

The S parameter does not do anything on its own.

/S      Modifies the treatment of string after /C or /K (see below) 
/C      Carries out the command specified by string and then terminates  
/K      Carries out the command specified by string but remains  

Try something like this instead

Call Shell("cmd.exe /S /K" & "perl a.pl c:\temp", vbNormalFocus)

You may not even need to add "cmd.exe" to this command unless you want a command window to open up when this is run. Shell should execute the command on its own.

Shell("perl a.pl c:\temp")

-Edit-
To wait for the command to finish you will have to do something like @Nate Hekman shows in his answer here

Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1

wsh.Run "cmd.exe /S /C perl a.pl c:\temp", windowStyle, waitOnReturn

This works:

<img src="invalid_link"
     onerror="this.onerror=null;this.src='https://placeimg.com/200/300/animals';"
>

Live demo: http://jsfiddle.net/oLqfxjoz/

As Nikola pointed out in the comment below, in case the backup URL is invalid as well, some browsers will trigger the "error" event again which will result in an infinite loop. We can guard against this by simply nullifying the "error" handler via this.onerror=null;.

I added this and it worked fine for me.

web.api

config.EnableCors();

Then you will call the model using cors:

In a controller you will add at the top for global scope or on each class. It's up to you.

 [EnableCorsAttribute("http://localhost:51003/", "*", "*")]

Also, when your pushing this data to Angular it wants to see the .cshtml file being called as well, or it will push the data but not populate your view.

(function () {
    "use strict";
    angular.module('common.services',
        ['ngResource'])
    .constant('appSettings',
    {
        serverPath: "http://localhost:51003/About"
    });
}());

//Replace URL with the appropriate path from production server.

I hope this helps anyone out, it took me a while to understand Entity Framework, and why CORS is so useful.

7 bit ASCII?

If your Tardis just landed in 1963, and you just want the 7 bit printable ASCII chars, you can rip out everything from 0-31 and 127-255 with this:

$string = preg_replace('/[\x00-\x1F\x7F-\xFF]/', '', $string);

It matches anything in range 0-31, 127-255 and removes it.

8 bit extended ASCII?

You fell into a Hot Tub Time Machine, and you're back in the eighties. If you've got some form of 8 bit ASCII, then you might want to keep the chars in range 128-255. An easy adjustment - just look for 0-31 and 127

$string = preg_replace('/[\x00-\x1F\x7F]/', '', $string);

UTF-8?

Ah, welcome back to the 21st century. If you have a UTF-8 encoded string, then the /u modifier can be used on the regex

$string = preg_replace('/[\x00-\x1F\x7F]/u', '', $string);

This just removes 0-31 and 127. This works in ASCII and UTF-8 because both share the same control set range (as noted by mgutt below). Strictly speaking, this would work without the /u modifier. But it makes life easier if you want to remove other chars...

If you're dealing with Unicode, there are potentially many non-printing elements, but let's consider a simple one: NO-BREAK SPACE (U+00A0)

In a UTF-8 string, this would be encoded as 0xC2A0. You could look for and remove that specific sequence, but with the /u modifier in place, you can simply add \xA0 to the character class:

$string = preg_replace('/[\x00-\x1F\x7F\xA0]/u', '', $string);

Addendum: What about str_replace?

preg_replace is pretty efficient, but if you're doing this operation a lot, you could build an array of chars you want to remove, and use str_replace as noted by mgutt below, e.g.

//build an array we can re-use across several operations
$badchar=array(
    // control characters
    chr(0), chr(1), chr(2), chr(3), chr(4), chr(5), chr(6), chr(7), chr(8), chr(9), chr(10),
    chr(11), chr(12), chr(13), chr(14), chr(15), chr(16), chr(17), chr(18), chr(19), chr(20),
    chr(21), chr(22), chr(23), chr(24), chr(25), chr(26), chr(27), chr(28), chr(29), chr(30),
    chr(31),
    // non-printing characters
    chr(127)
);

//replace the unwanted chars
$str2 = str_replace($badchar, '', $str);

Intuitively, this seems like it would be fast, but it's not always the case, you should definitely benchmark to see if it saves you anything. I did some benchmarks across a variety string lengths with random data, and this pattern emerged using php 7.0.12

     2 chars str_replace     5.3439ms preg_replace     2.9919ms preg_replace is 44.01% faster
     4 chars str_replace     6.0701ms preg_replace     1.4119ms preg_replace is 76.74% faster
     8 chars str_replace     5.8119ms preg_replace     2.0721ms preg_replace is 64.35% faster
    16 chars str_replace     6.0401ms preg_replace     2.1980ms preg_replace is 63.61% faster
    32 chars str_replace     6.0320ms preg_replace     2.6770ms preg_replace is 55.62% faster

   128 chars str_replace    12.7239ms preg_replace     7.5412ms preg_replace is 40.73% faster
   256 chars str_replace    19.8820ms preg_replace    17.1330ms preg_replace is 13.83% faster
   512 chars str_replace    34.3399ms preg_replace    34.0221ms preg_replace is  0.93% faster
  1024 chars str_replace    57.1141ms preg_replace    67.0300ms str_replace  is 14.79% faster
  2048 chars str_replace    94.7111ms preg_replace   123.3189ms str_replace  is 23.20% faster
  4096 chars str_replace   227.7029ms preg_replace   258.3771ms str_replace  is 11.87% faster
  8192 chars str_replace   506.3410ms preg_replace   555.6269ms str_replace  is  8.87% faster
 16384 chars str_replace  1116.8811ms preg_replace  1098.0589ms preg_replace is  1.69% faster
 32768 chars str_replace  2299.3128ms preg_replace  2222.8632ms preg_replace is  3.32% faster

The timings themselves are for 10000 iterations, but what's more interesting is the relative differences. Up to 512 chars, I was seeing preg_replace alway win. In the 1-8kb range, str_replace had a marginal edge.

I thought it was interesting result, so including it here. The important thing is not to take this result and use it to decide which method to use, but to benchmark against your own data and then decide.

A cookie is basically just an item in a dictionary. Each item has a key and a value. For authentication, the key could be something like 'username' and the value would be the username. Each time you make a request to a website, your browser will include the cookies in the request, and the host server will check the cookies. So authentication can be done automatically like that.

To set a cookie, you just have to add it to the response the server sends back after requests. The browser will then add the cookie upon receiving the response.

There are different options you can configure for the cookie server side, like expiration times or encryption. An encrypted cookie is often referred to as a signed cookie. Basically the server encrypts the key and value in the dictionary item, so only the server can make use of the information. So then cookie would be secure.

A browser will save the cookies set by the server. In the HTTP header of every request the browser makes to that server, it will add the cookies. It will only add cookies for the domains that set them. Example.com can set a cookie and also add options in the HTTP header for the browsers to send the cookie back to subdomains, like sub.example.com. It would be unacceptable for a browser to ever sends cookies to a different domain.

How to set bootstrap navbar active class with Angular JS?

Which is:

Use ng-controller to run a single controller outside of the ng-view:

<div class="collapse navbar-collapse" ng-controller="HeaderController">
    <ul class="nav navbar-nav">
        <li ng-class="{ active: isActive('/')}"><a href="/">Home</a></li>
        <li ng-class="{ active: isActive('/dogs')}"><a href="/dogs">Dogs</a></li>
        <li ng-class="{ active: isActive('/cats')}"><a href="/cats">Cats</a></li>
    </ul>
</div>
<div ng-view></div>

and include in controllers.js:

function HeaderController($scope, $location) 
{ 
    $scope.isActive = function (viewLocation) { 
        return viewLocation === $location.path();
    };
}

While cloning you might be using SSH in the dropdown list. Change it to Https and then clone.

You can do it with drop_duplicates as you wanted

# initialisation
d = pd.DataFrame({'A' : [1,1,2,3,3], 'B' : [2,2,7,4,4],  'C' : [1,4,1,0,8]})

d = d.sort_values("C", ascending=False)
d = d.drop_duplicates(["A","B"])

If it's important to get the same order

d = d.sort_index()

Well, I believe it's an "Old but Gold" question. The answer is: "It depends!". The performances are such a delicate subject that it would be too much silly to say: "Never use subqueries, always join". In the following links, you'll find some basic best practices that I have found to be very helpful:

• Optimizing Subqueries
• Optimizing Subqueries with Semijoin Transformations
• Rewriting Subqueries as Joins

I have a table with 50000 elements, the result i was looking for was 739 elements.

My query at first was this:

SELECT  p.id,
    p.fixedId,
    p.azienda_id,
    p.categoria_id,
    p.linea,
    p.tipo,
    p.nome
FROM prodotto p
WHERE p.azienda_id = 2699 AND p.anno = (
    SELECT MAX(p2.anno) 
    FROM prodotto p2 
    WHERE p2.fixedId = p.fixedId 
)

and it took 7.9s to execute.

My query at last is this:

SELECT  p.id,
    p.fixedId,
    p.azienda_id,
    p.categoria_id,
    p.linea,
    p.tipo,
    p.nome
FROM prodotto p
WHERE p.azienda_id = 2699 AND (p.fixedId, p.anno) IN
(
    SELECT p2.fixedId, MAX(p2.anno)
    FROM prodotto p2
    WHERE p.azienda_id = p2.azienda_id
    GROUP BY p2.fixedId
)

and it took 0.0256s

Good SQL, good.

It seems to me, that it is by design that this file is empty.

A similar question has been asked here: https://stackoverflow.com/questions/2567432/ubuntu-apache-httpd-conf-or-apache2-conf

So, you should have a look for /etc/apache2/apache2.conf

If you are using PyCharm IDE, then you can run that individual test or all tests using Run toolbar. The Run tool window displays output generated by your application and you can see all the print statements in there as part of test output.

This isn't an answer. I was struggling but then realized that my install was trying to connect to internet to download dependencies.

So, I downloaded and installed dependencies first and then installed with below command. It worked

python -m pip install filename.tar.gz

As per node js doc process.cwd()

cwd is a method of global object process, returns a string value which is the current working directory of the Node.js process.

As per node js doc __dirname

The directory name of current script as a string value. __dirname is not actually a global but rather local to each module.

Let me explain with example,

suppose we have a main.js file resides inside C:/Project/main.js and running node main.js both these values return same file

or simply with following folder structure

Project 
+-- main.js
+--lib
   +-- script.js

main.js

console.log(process.cwd())
// C:\Project
console.log(__dirname)
// C:\Project
console.log(__dirname===process.cwd())
// true

suppose we have another file script.js files inside a sub directory of project ie C:/Project/lib/script.js and running node main.js which require script.js

main.js

require('./lib/script.js')
console.log(process.cwd())
// C:\Project
console.log(__dirname)
// C:\Project
console.log(__dirname===process.cwd())
// true

script.js

console.log(process.cwd())
// C:\Project
console.log(__dirname)
// C:\Project\lib
console.log(__dirname===process.cwd())
// false

if you want read and write on your extra field, you can use a new custom serializer, that extends serializers.Serializer, and use it like this

class ExtraFieldSerializer(serializers.Serializer):
    def to_representation(self, instance): 
        # this would have the same as body as in a SerializerMethodField
        return 'my logic here'

    def to_internal_value(self, data):
        # This must return a dictionary that will be used to
        # update the caller's validation data, i.e. if the result
        # produced should just be set back into the field that this
        # serializer is set to, return the following:
        return {
          self.field_name: 'Any python object made with data: %s' % data
        }

class MyModelSerializer(serializers.ModelSerializer):
    my_extra_field = ExtraFieldSerializer(source='*')

    class Meta:
        model = MyModel
        fields = ['id', 'my_extra_field']

i use this in related nested fields with some custom logic

The solution for me when running into this Incorrect string value: '\xF8' for column error using scriptcase was to be sure that my database is set up for utf8 general ci and so are my field collations. Then when I do my data import of a csv file I load the csv into UE Studio then save it formatted as utf8 and Voila! It works like a charm, 29000 records in there no errors. Previously I was trying to import an excel created csv.

When you want to access an element, you have to first dereference your pointer, and then index the element you want (which is also dereferncing). i.e. you need to do:

printf("\nvalue:%c", (*ptr)[0]); , which is the same as *((*ptr)+0)

Note that working with pointer to arrays are not very common in C. instead, one just use a pointer to the first element in an array, and either deal with the length as a separate element, or place a senitel value at the end of the array, so one can learn when the array ends, e.g.

char arr[5] = {'a','b','c','d','e',0}; 
char *ptr = arr; //same as char *ptr = &arr[0]

printf("\nvalue:%c", ptr[0]);

You should have a look at the httplib module. It should let you make whatever sort of HTTP request you want.

I don't know if there is a better way, but the following describes how I did it with a counter and background worker thread.

private object _lock = new object();
private int _runningThreads = 0;

private int Counter{
    get{
        lock(_lock)
            return _runningThreads;
    }
    set{
        lock(_lock)
            _runningThreads = value;
    }
}

Now whenever you create a worker thread, increment the counter:

var t = new BackgroundWorker();
// Add RunWorkerCompleted handler

// Start thread
Counter++;

In work completed, decrement the counter:

private void RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    Counter--;
}

Now you can check for the counter anytime to see if any thread is running:

if(Couonter>0){
    // Some thread is yet to finish.
}

In Ruby on Rails 6.0.1 go to config > locales > application.rb y agrega lo siguiente:

require_relative 'boot'

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module CrudRubyOnRails6
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 6.0

    config.active_record.default_timezone = :local
    config.time_zone = 'Lima'

    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration can go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded after loading
    # the framework and any gems in your application.
  end
end

You can see that I am configuring the time zone with 2 lines:

config.active_record.default_timezone =: local
config.time_zone = 'Lima'

I hope it helps those who are working with Ruby on Rails 6.0.1

On windows platform, you have 2 choices:

1. In a command line terminal, type

   c:\python23\python xxxx.py

2. Open the python editor IDLE from the menu, and open xxxx.py, then press F5 to run it.

For your posted code, the error is at this line:

def main(url, out_folder="C:\asdf\"):

It should be:

def main(url, out_folder="C:\\asdf\\"):

For this you probably want myString.PadRight(totalLength, charToInsert).

See String.PadRight Method (Int32) for more info.

How to set display_errors to Off in my own file without using php.ini

You can do this using ini_set() function. Read more about ini_set() here (https://www.php.net/manual/en/function.ini-set.php)

1. Go to your header.php or index.php
2. add this code ini_set('display_errors', FALSE);

To check the output without accessing php.ini file

$displayErrors = (ini_get('display_errors') == 1) ? 'On' : 'Off';
$PHPCore = array(
    'Display error' => $displayErrors
    // add other details for more output
);
foreach ($PHPCore as $key => $value) {
    echo "$key: $value";
}

Here's an interactive session showing some of the steps in @TokenMacGuy's one-liner. First he uses the map function to convert each item in the list to a string (actually, he's making a new list, not converting the items in the old list). Then he's using the string method join to combine those strings with ', ' between them. The rest is just string formatting, which is pretty straightforward. (Edit: this instance is straightforward; string formatting in general can be somewhat complex.)

Note that using join is a simple and efficient way to build up a string from several substrings, much more efficient than doing it by successively adding strings to strings, which involves a lot of copying behind the scenes.

>>> mylist = ['x', 3, 'b']
>>> m = map(str, mylist)
>>> m
['x', '3', 'b']
>>> j = ', '.join(m)
>>> j
'x, 3, b'

Here is the docs from the zsh man pages under STARTUP/SHUTDOWN FILES section.

   Commands  are  first  read from /etc/zshenv this cannot be overridden.
   Subsequent behaviour is modified by the RCS and GLOBAL_RCS options; the
   former  affects all startup files, while the second only affects global
   startup files (those shown here with an path starting with  a  /).   If
   one  of  the  options  is  unset  at  any point, any subsequent startup
   file(s) of the corresponding type will not be read.  It is also  possi-
   ble  for  a  file  in  $ZDOTDIR  to  re-enable GLOBAL_RCS. Both RCS and
   GLOBAL_RCS are set by default.

   Commands are then read from $ZDOTDIR/.zshenv.  If the shell is a  login
   shell,  commands  are  read from /etc/zprofile and then $ZDOTDIR/.zpro-
   file.  Then, if the  shell  is  interactive,  commands  are  read  from
   /etc/zshrc  and then $ZDOTDIR/.zshrc.  Finally, if the shell is a login
   shell, /etc/zlogin and $ZDOTDIR/.zlogin are read.

From this we can see the order files are read is:

/etc/zshenv    # Read for every shell
~/.zshenv      # Read for every shell except ones started with -f
/etc/zprofile  # Global config for login shells, read before zshrc
~/.zprofile    # User config for login shells
/etc/zshrc     # Global config for interactive shells
~/.zshrc       # User config for interactive shells
/etc/zlogin    # Global config for login shells, read after zshrc
~/.zlogin      # User config for login shells
~/.zlogout     # User config for login shells, read upon logout
/etc/zlogout   # Global config for login shells, read after user logout file

Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors at your server side.

You can fetch request using mode: 'cors'. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.

So in both condition you need to configure cors in your server or you need to use custom proxy server.

you can download USBview and get all the information you need. Along with the list of devices it will also show you the configuration of each device.

For Linux:

/opt/lampp/bin/mysql -u root -p

To use just 'mysql -u root -p' command then add '/opt/lampp/bin' to the PATH of the environment variables.

I have written an incredibly simple (5 lines of code) plugin for exactly this functionality:

http://byrichardpowell.github.com/jquery-or/

It allows you to effectively say "get this element, or if that element doesnt exist, use this element". For example:

$( '#doesntExist' ).or( '#exists' );

Whilst the accepted answer provides similar functionality to this, if both selectors (before & after the comma) exist, both selectors will be returned.

I hope it proves helpful to anyone who might land on this page via google.

select count(isnull(NullableColumn,-1))

See the Parameter Expansion section in the Bash man page. A[@] returns the contents of the array, :1:2 takes a slice of length 2, starting at index 1.

A=( foo bar "a  b c" 42 )
B=("${A[@]:1:2}")
C=("${A[@]:1}")       # slice to the end of the array
echo "${B[@]}"        # bar a  b c
echo "${B[1]}"        # a  b c
echo "${C[@]}"        # bar a  b c 42
echo "${C[@]: -2:2}"  # a  b c 42 # The space before the - is necesssary

Note that the fact that "a b c" is one array element (and that it contains an extra space) is preserved.

This is another solution as well

• One simple way is replace \n(newline) with ","(double-quote comma double-quote) after this append double-quote in the start and end of file.

example:

      AliceBlue
      AntiqueWhite
      Aqua
      Aquamarine
      Beige

• Replcae \n with ","

    AliceBlue","AntiqueWhite","Aqua","Aquamarine","Beige
  

• Now append "(double-quote) at the start and end

   "AliceBlue","AntiqueWhite","Aqua","Aquamarine","Beige"
  

If your text contains blank lines in between you can use regular expression \n+ instead of \n

example:

      AliceBlue

      AntiqueWhite
      Aqua


      Aquamarine
      Beige

• Replcae \n+ with "," (in regex mode)

    AliceBlue","AntiqueWhite","Aqua","Aquamarine","Beige
  

• Now append "(double-quote) at the start and end

   "AliceBlue","AntiqueWhite","Aqua","Aquamarine","Beige"

Since there is a delimiter, you should use that instead of worrying about how long the md5 is.

>>> s = "416d76b8811b0ddae2fdad8f4721ddbe|d4f656ee006e248f2f3a8a93a8aec5868788b927|12a5f648928f8e0b5376d2cc07de8e4cbf9f7ccbadb97d898373f85f0a75c47f"
>>> md5sum, delim, rest = s.partition('|')
>>> md5sum
'416d76b8811b0ddae2fdad8f4721ddbe'

Alternatively

>>> md5sum, sha1sum, sha5sum = s.split('|')
>>> md5sum
'416d76b8811b0ddae2fdad8f4721ddbe'
>>> sha1sum
'd4f656ee006e248f2f3a8a93a8aec5868788b927'
>>> sha5sum

Cool @derek-kromm, Your answer is accepted and correct, But I am wondering if we need to alter more than the column. Here is how we can do.

ALTER TABLE tbl_name 
ALTER COLUMN col_name TYPE varchar (11), 
ALTER COLUMN col_name2 TYPE varchar (11),
ALTER COLUMN col_name3 TYPE varchar (11);

You can use a variable to count places in the array, so when ever you add a new element, you put it in the right place. For example:

int a = 0;
int arr[5] = { };
arr[a] = 6;
a++;

Please, Check this out, I hope it's help

<div class="row">
 <iframe class="col-lg-12 col-md-12 col-sm-12" src="http://www.w3schools.com">

</div>

The appropriate way for doing this:

@app.route('/')
def index():
    if form.validate_on_submit():
        if 'download' in request.form:
            pass # do something
        elif 'watch' in request.form:
            pass # do something else

Put watch and download buttons into your template:

<input type="submit" name="download" value="Download">
<input type="submit" name="watch" value="Watch">

String.prototype.padLeft = function(pad) {
        var s = Array.apply(null, Array(pad)).map(function() { return "0"; }).join('') + this;
        return s.slice(-1 * Math.max(this.length, pad));
    };

usage:

1. "123".padLeft(2) returns: "123"
2. "12".padLeft(2) returns: "12"
3. "1".padLeft(2) returns: "01"

The meaning of the completely undocumented error 800A03EC (shame on Microsoft!) is something like "OPERATION NOT SUPPORTED".

It may happen

• when you open a document that has a content created by a newer Excel version, which your current Excel version does not understand.
• when you save a document to the same path where you have loaded it from (file is already open and locked)

But mostly you will see this error due to severe bugs in Excel.

• For example Microsoft.Office.Interop.Excel.Picture has a property "Enabled". When you call it you should receive a bool value. But instead you get an error 800A03EC. This is a bug.
• And there is a very fat bug in Exel 2013 and 2016: When you automate an Excel process and set Application.Visible=true and Application.WindowState = XlWindowState.xlMinimized then you will get hundreds of 800A03EC errors from different functions (like Range.Merge(), CheckBox.Text, Shape.TopLeftCell, Shape.Locked and many more). This bug does not exist in Excel 2007 and 2010.

x='buffalo'

Try ABCpdf from webSupergoo. It's a commercial solution, not open source, but the standard edition can be obtained free of charge and will do what you are asking.

ABCpdf fully supports HTML and CSS, live forms and live links. It also uses Microsoft XML Core Services (MSXML) while rendering, so the results should match exactly what you see in Internet Explorer.

The on-line demo can be used to test HTML to PDF rendering without needing to install any software. See: http://www.abcpdfeditor.com/

The following C# code example shows how to render a single page HTML document.

Doc theDoc = new Doc();
theDoc.AddImageUrl("http://www.example.com/");
theDoc.Save("htmlimport.pdf");
theDoc.Clear();

To render multiple pages you'll need the AddImageToChain function, documented here: http://www.websupergoo.com/helppdf7net/source/5-abcpdf6/doc/1-methods/addimagetochain.htm

To make height:100% work for the inner div, you have to set a height for the parent td. For my particular case it worked using height:100%. This made the inner div height stretch, while the other elements of the table didn't allow the td to become too big. You can of course use other values than 100%

If you want to also make the table cell have a fixed height so that it does not get bigger based on content (to make the inner div scroll or hide overflow), that is when you have no choice but do some js tricks. The parent td will need to have the height specified in a non relative unit (not %). And you will most probably have no choice but to calculate that height using js. This would also need the table-layout:fixed style set for the table element

Another simple one-liner that hasn't been mentioned here:

value = line.split("Path=", 1)[-1]

This will also work properly for various edge cases:

>>> print("prefixfoobar".split("foo", 1)[-1])
"bar"

>>> print("foofoobar".split("foo", 1)[-1])
"foobar"

>>> print("foobar".split("foo", 1)[-1])
"bar"

>>> print("bar".split("foo", 1)[-1])
"bar"

>>> print("".split("foo", 1)[-1])
""

No.

The content-type should be whatever it is known to be, if you know it. application/octet-stream is defined as "arbitrary binary data" in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be saved to disk, and from that point on be outside of anything "webby". Or to look at it from another direction; the only thing one can safely do with application/octet-stream is to save it to file and hope someone else knows what it's for.

You can combine the use of Content-Disposition with other content-types, such as image/png or even text/html to indicate you want saving rather than display. It used to be the case that some browsers would ignore it in the case of text/html but I think this was some long time ago at this point (and I'm going to bed soon so I'm not going to start testing a whole bunch of browsers right now; maybe later).

RFC 2616 also mentions the possibility of extension tokens, and these days most browsers recognise inline to mean you do want the entity displayed if possible (that is, if it's a type the browser knows how to display, otherwise it's got no choice in the matter). This is of course the default behaviour anyway, but it means that you can include the filename part of the header, which browsers will use (perhaps with some adjustment so file-extensions match local system norms for the content-type in question, perhaps not) as the suggestion if the user tries to save.

Hence:

Content-Type: application/octet-stream
Content-Disposition: attachment; filename="picture.png"

Means "I don't know what the hell this is. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: attachment; filename="picture.png"

Means "This is a PNG image. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: inline; filename="picture.png"

Means "This is a PNG image. Please display it unless you don't know how to display PNG images. Otherwise, or if the user chooses to save it, we recommend the name picture.png for the file you save it as".

Of those browsers that recognise inline some would always use it, while others would use it if the user had selected "save link as" but not if they'd selected "save" while viewing (or at least IE used to be like that, it may have changed some years ago).

The dataset that I used had a lot of quote marks (") used extraneous of the formatting. I was able to fix the error by including this parameter for read_csv():

quoting=3 # 3 correlates to csv.QUOTE_NONE for pandas

Please try this... This works for me..

In adapter,take a sparse boolean array.

SparseBooleanArray sparseBooleanArray;

In constructor initialise this,

   sparseBooleanArray=new SparseBooleanArray();

In bind holder add,

@Override
public void onBindViewHolder(DispositionViewHolder holder, final int position) {
   holder.tv_disposition.setText(dispList.get(position).getName());
    if(sparseBooleanArray.get(position,false))
    {
        holder.rd_disp.setChecked(true);
    }
    else
    {
        holder.rd_disp.setChecked(false);


    }
    setClickListner(holder,position);
}

private void setClickListner(final DispositionViewHolder holder, final int position) {
    holder.rd_disp.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            sparseBooleanArray.clear();
            sparseBooleanArray.put(position, true);
            notifyDataSetChanged();


        }
    });
}

rd_disp is radio button in xml file.

So when the recycler view load the items,in bindView Holder it check whether the sparseBooleanArray contain the value "true" correspnding to its position.

If the value returned is true then we set the radio button selection true.Else we set the selection false. In onclickHolder I have cleared the sparseArray and set the value true corresponding to that position. When I call notify datasetChange it again call the onBindViewHolder and the condition are checked again. This makes our selection to only select particular radio.

It looks like you forgot to include the ngRoute module in your dependency for myApp.

In Angular 1.2, they've made ngRoute optional (so you can use third-party route providers, etc.) and you have to explicitly depend on it in modules, along with including the separate file.

'use strict';

angular.module('myApp', ['ngRoute']).
    config(['$routeProvider', function($routeProvider) {
$routeProvider.otherwise({redirectTo: '/home'});
}]);

You can do this with .htaccess:

php_value upload_max_filesize 20M
php_value post_max_size 20M

array_values does the job :

$myArray  = array_values($myArray);

Also some other php function do not preserve the keys, i.e. reset the index.

    return checkdate(substr($yyyymmdd, 5, 2), substr($yyyymmdd, 8), substr($yyyymmdd, 0, 4)) 
        && (substr($yyyymmdd, 4, 1) === '-') 
        && (substr($yyyymmdd, 7, 1) === '-');

To create a Twitter share link with a photo, you first need to tweet out the photo from your Twitter account. Once you've tweeted it out, you need to grab the pic.twitter.com link and place that inside your twitter share url.

note: You won't be able to see the pic.twitter.com url so what I do is use a separate account and hit the retweet button. A modal will pop up with the link inside.

You Twitter share link will look something like this:

<a href="https://twitter.com/home?status=This%20photo%20is%20awesome!%20Check%20it%20out:%20pic.twitter.com/9Ee63f7aVp">Share on Twitter</a>

When I ran mongod.exe from Windows Terminal I got a message Unrecognized option: mp. There was an empty mp: in the end of mongod.cfg. Removing that solved the problem for me.

First off, are you setting your desired JRE or your desired JDK?

Even if your Eclipse is set up properly, there might be a wacky project-specific setting somewhere. You can open up a context menu on a given Java project in the Project Explorer and select Properties > Java Compiler to check on that.

If none of that helps, leave a comment and I'll take another look.

If it is a valid change.

you can change the property.

Tools --> Options --> Designers --> Table and Database designers --> Uncheck --> Prevent saving changes that required table re-creation.

Now you can easily change the column name without recreating the table or losing u r records.

According to the doc, the default implementation of hashCode will return some integer that differ for every object

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation
technique is not required by the JavaTM programming language.)

However some time you want the hash code to be the same for different object that have the same meaning. For example

Student s1 = new Student("John", 18);
Student s2 = new Student("John", 18);
s1.hashCode() != s2.hashCode(); // With the default implementation of hashCode

This kind of problem will be occur if you use a hash data structure in the collection framework such as HashTable, HashSet. Especially with collection such as HashSet you will end up having duplicate element and violate the Set contract.

In my case finish() executed immediately after a dialog has shown.

To unescape HTML entities* in JavaScript you can use small library html-escaper: npm install html-escaper

import {unescape} from 'html-escaper';

unescape('escaped string');

Or unescape function from Lodash or Underscore, if you are using it.

*) please note that these functions don't cover all HTML entities, but only the most common ones, i.e. &, <, >, ', ". To unescape all HTML entities you can use he library.

If you don't have Python 2.6 or higher, the alternative is to write an explicit for loop:

def set_list_intersection(set_list):
  if not set_list:
    return set()
  result = set_list[0]
  for s in set_list[1:]:
    result &= s
  return result

set_list = [set([1, 2]), set([1, 3]), set([1, 4])]
print set_list_intersection(set_list)
# Output: set([1])

You can also use reduce:

set_list = [set([1, 2]), set([1, 3]), set([1, 4])]
print reduce(lambda s1, s2: s1 & s2, set_list)
# Output: set([1])

However, many Python programmers dislike it, including Guido himself:

About 12 years ago, Python aquired lambda, reduce(), filter() and map(), courtesy of (I believe) a Lisp hacker who missed them and submitted working patches. But, despite of the PR value, I think these features should be cut from Python 3000.

So now reduce(). This is actually the one I've always hated most, because, apart from a few examples involving + or *, almost every time I see a reduce() call with a non-trivial function argument, I need to grab pen and paper to diagram what's actually being fed into that function before I understand what the reduce() is supposed to do. So in my mind, the applicability of reduce() is pretty much limited to associative operators, and in all other cases it's better to write out the accumulation loop explicitly.

What I see in this case is that if I pull the client machine's network cable and make the call, the ajax success handler is called (why, I don't know), and the data parameter is an empty string. So if you factor out the real error handling, you can do something like this:

function handleError(jqXHR, textStatus, errorThrown) {
    ...
}

jQuery.ajax({
    ...
    success: function(data, textStatus, jqXHR) {
        if (data == "") handleError(jqXHR, "clientNetworkError", "");
    },
    error: handleError
});

You need to use the -i flag:

ssh-copy-id -i my.key.pub 10.10.1.1

From the man page:

If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your ssh-agent. Otherwise, if this: ssh-add -L provides any output, it uses that in preference to the identity file

Think about what

if ((state != 10) || (state != 15) || (state != 19) || (state != 22) || (state != 33) || (state != 39) || (state != 47) || (state != 48) || (state != 49) || (state != 51))

means. || means "or." The negation of this is (by DeMorgan's Laws):

state == 10 && state == 15 && state == 19...

In other words, the only way that this could be false if if a state equals 10, 15, and 19 (and the rest of the numbers in your or statement) at the same time, which is impossible.

Thus, this statement will always be true. State 15 will never equal state 10, for example, so it's always true that state will either not equal 10 or not equal 15.

Change || to &&.

Also, in most languages, the following:

if (x) {
  return true;
}
else {
  return false;
}

is not necessary. In this case, the method returns true exactly when x is true and false exactly when x is false. You can just do:

return x;

[i for i in enumerate(['a','b','c'])]

Result:

[(0, 'a'), (1, 'b'), (2, 'c')]

In laravel-8 you can use like this

 Route::group(['namespace'=>'App\Http\Controllers', 'prefix'=>'admin',
 'as'=>'admin.','middleware'=>['auth:sanctum', 'verified']], function()
{
    Route::resource('/dashboard', 'DashboardController')->only([
        'index'
    ]);
});

Marquee (<marquee>) is a deprecated and not a valid HTML tag. You can use many jQuery plugins to do. One of it, is jQuery News Ticker. There are many more!

I think of this as a two-step process:

1. subset the original data frame according to the filter supplied (Believe==FALSE); then

2. get the row count of this subset

For the first step, the subset function is a good way to do this (just an alternative to ordinary index or bracket notation).

For the second step, i would use dim or nrow

One advantage of using subset: you don't have to parse the result it returns to get the result you need--just call nrow on it directly.

so in your case:

v = nrow(subset(Santa, Believe==FALSE))     # 'subset' returns a data.frame

or wrapped in an anonymous function:

>> fnx = function(fac, lev){nrow(subset(Santa, fac==lev))}

>> fnx(Believe, TRUE)
      3

Aside from nrow, dim will also do the job. This function returns the dimensions of a data frame (rows, cols) so you just need to supply the appropriate index to access the number of rows:

v = dim(subset(Santa, Believe==FALSE))[1] 

An answer to the OP posted before this one shows the use of a contingency table. I don't like that approach for the general problem as recited in the OP. Here's the reason. Granted, the general problem of how many rows in this data frame have value x in column C? can be answered using a contingency table as well as using a "filtering" scheme (as in my answer here). If you want row counts for all values for a given factor variable (column) then a contingency table (via calling table and passing in the column(s) of interest) is the most sensible solution; however, the OP asks for the count of a particular value in a factor variable, not counts across all values. Aside from the performance hit (might be big, might be trivial, just depends on the size of the data frame and the processing pipeline context in which this function resides). And of course once the result from the call to table is returned, you still have to parse from that result just the count that you want.

So that's why, to me, this is a filtering rather than a cross-tab problem.

Are you sure the odbc connector is well created ? if not check the step "Create an ODBC Connection" again

EDIT: Connection without DSN from php.net

// Microsoft Access

$connection = odbc_connect("Driver={Microsoft Access Driver (*.mdb)};Dbq=$mdbFilename", $user, $password);

in your case it might be if your filename is northwind and your file extension mdb:

$connection = odbc_connect("Driver={Microsoft Access Driver (*.mdb)};Dbq=northwind", "", "");

@royalsampler said:

Go to the Servers view in Eclipse then right click on the server and click Open. The log files are stored in a folder realative to the path in the "Server path" field.

Since the path field is uneditable, you can also "Open Launch Configuration", click Arguments tab, copy the VM argument for catalina.base (within quotes). This is the full path of your WTP webapp directory. Copying the value to the clipboard can save you the laborious task of browsing the file system to the path.

Also note you should be seeing the output to the log file in your Console view as you run or debug.

In that scenario use map, you don't need a new Observable for it.

you should use Exceptions.propagate, which is a wrapper so you can send those checked exceptions to the rx mechanism

Observable<String> obs = Observable.from(jsonFile).map(new Func1<File, String>() { 
    @Override public String call(File file) {
        try { 
            return new Gson().toJson(new FileReader(file), Object.class);
        } catch (FileNotFoundException e) {
            throw Exceptions.propagate(t); /will propagate it as error
        } 
    } 
});

You then should handle this error in the subscriber

obs.subscribe(new Subscriber<String>() {
    @Override 
    public void onNext(String s) { //valid result }

    @Override 
    public void onCompleted() { } 

    @Override 
    public void onError(Throwable e) { //e might be the FileNotFoundException you got }
};); 

There is an excellent post for it: http://blog.danlew.net/2015/12/08/error-handling-in-rxjava/

The answer given by @Aron works, but it didn't work for me as I was trying to convert timestamp starting from 1980. So I made few changes as follows

function ConvertUnixTimeToDateForLeap(UNIX_Timestamp) {_x000D_
    var dateObj = new Date(1980, 0, 1, 0, 0, 0, 0);_x000D_
    dateObj.setSeconds(dateObj.getSeconds() + UNIX_Timestamp);_x000D_
    return dateObj;  _x000D_
}_x000D_
_x000D_
document.body.innerHTML = 'TimeStamp : ' + ConvertUnixTimeToDateForLeap(1269700200);

So if you have a timestamp starting from another decade or so, just use this. It saved a lot of headache for me.

You can use the following steps, its worked for me to drop table with constraint,solution already explained in the above comment, i just added screen shot for that -

I extended ??s???? K's answer to make the code full and workable. So, when you finish filling your 'all_thumbs' list, you should put its content one by one into the bundle and then into the intent:

Bundle bundle = new Bundle();

for (int i = 0; i<all_thumbs.size(); i++)
bundle.putSerializable("extras"+i, all_thumbs.get(i));

intent.putExtras(bundle);

In order to get the extras from the intent, you need:

Bundle bundle = new Bundle();
List<Thumbnail> thumbnailObjects = new ArrayList<Thumbnail>();

// collect your Thumbnail objects
for (String key : bundle.keySet()) {
thumbnailObjects.add((Thumbnail) bundle.getSerializable(key));
}

// for example, in order to get a value of the 3-rd object you need to:
String label = thumbnailObjects.get(2).get_label();

Advantage of Serializable is its simplicity. However, I would recommend you to consider using Parcelable method when you need transfer many data, because Parcelable is specifically designed for Android and it is more efficient than Serializable. You can create Parcelable class using:

1. an online tool - parcelabler
2. a plugin for Android Studion - Android Parcelable code generator

As per the docs, as of iOS 3.0, the UITableViewController class automatically resizes and repositions its table view when there is in-line editing of text fields. I think it's not sufficient to put the text field inside a UITableViewCell as some have indicated.

From the docs:

A table view controller supports inline editing of table view rows; if, for example, rows have embedded text fields in editing mode, it scrolls the row being edited above the virtual keyboard that is displayed.

Here is my solution. It uses AnimatorSet. AnimationSet library was too buggy to get working. This provides seamless and infinite transitions between fade in and out.

public static void setAlphaAnimation(View v) {
    ObjectAnimator fadeOut = ObjectAnimator.ofFloat(v, "alpha",  1f, .3f);
    fadeOut.setDuration(2000);
    ObjectAnimator fadeIn = ObjectAnimator.ofFloat(v, "alpha", .3f, 1f);
    fadeIn.setDuration(2000);

    final AnimatorSet mAnimationSet = new AnimatorSet();

    mAnimationSet.play(fadeIn).after(fadeOut);

    mAnimationSet.addListener(new AnimatorListenerAdapter() {
        @Override
        public void onAnimationEnd(Animator animation) {
            super.onAnimationEnd(animation);
            mAnimationSet.start();
        }
    });
    mAnimationSet.start();
}

char arr[50];
gets(arr);
int c=0,i,l;
l=strlen(arr);

    for(i=0;i<l;i++){
        if(arr[i]==32){
            printf("\n");
        }
        else
        printf("%c",arr[i]);
    }

Programming Language: PHP

// Inintialize URL to the variable 
$url = 'https://www.youtube.com/watch?v=qnMxsGeDz90'; 

// Use parse_url() function to parse the URL 
// and return an associative array which 
// contains its various components 
$url_components = parse_url($url); 

// Use parse_str() function to parse the 
// string passed via URL 
parse_str($url_components['query'], $params); 

// Display result 
echo 'v parameter value is '.$params['v'];

This worked for me. I hope, it will also help you :)

<input id="unpressed" type="submit" value=" " style="background:url(http://integritycontractingofva.com/images/go1.jpg) no-repeat;border:none;"/>

And use CSS to change the opacity of the "unpressed" image on hover:

#pressed, #unpressed{position:absolute; left:0px;}
#unpressed{opacity: 1; cursor: pointer;}
#unpressed:hover{opacity: 0;}

I use it for the blue "GO" button on this page

Alternatively, you can apply maven-compiler-plugin with appropriate java version by adding this to your pom.xml:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
</build>

If you have a flash FLA file that shows the FLV movie you can add a button inside the FLA file. This button can be given an action to load the URL.

on (release) {
  getURL("http://someurl/");
}

To make the button transparent you can place a square inside it that is moved to the hit-area frame of the button.

I think it would go too far to explain into depth with pictures how to go about in stackoverflow.

It doesn't?

For me, best and simplest way, Bootply http://www.bootply.com/lxa0FF9yhw#

First include Bootstrap to your project

Then include javascript file in which you write this code:

    $.fn.pageMe = function(opts){
    var $this = this,
        defaults = {
            perPage: 7,
            showPrevNext: false,
            hidePageNumbers: false
        },
        settings = $.extend(defaults, opts);

    var listElement = $this;
    var perPage = settings.perPage; 
    var children = listElement.children();
    var pager = $('.pager');

    if (typeof settings.childSelector!="undefined") {
        children = listElement.find(settings.childSelector);
    }

    if (typeof settings.pagerSelector!="undefined") {
        pager = $(settings.pagerSelector);
    }

    var numItems = children.size();
    var numPages = Math.ceil(numItems/perPage);

    pager.data("curr",0);

    if (settings.showPrevNext){
        $('<li><a href="#" class="prev_link">«</a></li>').appendTo(pager);
    }

    var curr = 0;
    while(numPages > curr && (settings.hidePageNumbers==false)){
        $('<li><a href="#" class="page_link">'+(curr+1)+'</a></li>').appendTo(pager);
        curr++;
    }

    if (settings.showPrevNext){
        $('<li><a href="#" class="next_link">»</a></li>').appendTo(pager);
    }

    pager.find('.page_link:first').addClass('active');
    pager.find('.prev_link').hide();
    if (numPages<=1) {
        pager.find('.next_link').hide();
    }
    pager.children().eq(1).addClass("active");

    children.hide();
    children.slice(0, perPage).show();

    pager.find('li .page_link').click(function(){
        var clickedPage = $(this).html().valueOf()-1;
        goTo(clickedPage,perPage);
        return false;
    });
    pager.find('li .prev_link').click(function(){
        previous();
        return false;
    });
    pager.find('li .next_link').click(function(){
        next();
        return false;
    });

    function previous(){
        var goToPage = parseInt(pager.data("curr")) - 1;
        goTo(goToPage);
    }

    function next(){
        goToPage = parseInt(pager.data("curr")) + 1;
        goTo(goToPage);
    }

    function goTo(page){
        var startAt = page * perPage,
            endOn = startAt + perPage;

        children.css('display','none').slice(startAt, endOn).show();

        if (page>=1) {
            pager.find('.prev_link').show();
        }
        else {
            pager.find('.prev_link').hide();
        }

        if (page<(numPages-1)) {
            pager.find('.next_link').show();
        }
        else {
            pager.find('.next_link').hide();
        }

        pager.data("curr",page);
        pager.children().removeClass("active");
        pager.children().eq(page+1).addClass("active");

    }
};

You need to give an id to the tbody of your table and to add a 'div' after the table for the pagination

     <table class="table" id="myTable">
            <thead>
                <tr>
                    <th>...</th>
                </tr>
            </thead>
            <tbody id="myTableBody">
            </tbody>
       </table>
       <div class="col-md-12 text-center">
           <ul class="pagination pagination-lg pager" id="myPager"></ul>
       </div>

When your table's data is loaded, just call this

$('#myTableBody').pageMe({pagerSelector:'#myPager',showPrevNext:true,hidePageNumbers:false,perPage:4});

where the 'perPage' value is to set how many elements per page you want to have.

var dict = File.ReadLines("test.txt")
               .Where(line => !string.IsNullOrWhitespace(line))
               .Select(line => line.Split(new char[] { '=' }, 2, 0))
               .ToDictionary(parts => parts[0], parts => parts[1]);


or 

    enter code here

line="[email protected][email protected]";
string[] tokens = line.Split(new char[] { '=' }, 2, 0);

ans:
tokens[0]=to
token[1][email protected][email protected]"

In Windows, even after installing graphviz-2.38.msi, you can add your own path in pydot.py (found under site-package folder)

 if os.sys.platform == 'win32':

    # Try and work out the equivalent of "C:\Program Files" on this
    # machine (might be on drive D:, or in a different language)
    #

    if os.environ.has_key('PROGRAMFILES'):

        # Note, we could also use the win32api to get this
        # information, but win32api may not be installed.

        path = os.path.join(os.environ['PROGRAMFILES'], 'ATT', 'GraphViz', 'bin')

    else:

        #Just in case, try the default...
        path = r"C:\PYTHON27\GraphViz\bin"  # add here.

Edit: Out of date answer, ECMAScript 2015 (ES6) standard javascript has a Map implementation, read here for more info: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map

var map = new Object(); // or var map = {};
map[myKey1] = myObj1;
map[myKey2] = myObj2;

function get(k) {
    return map[k];
}

//map[myKey1] == get(myKey1);

By definition, a UUID is 32 hexadecimal digits, separated in 5 groups by hyphens, just as you have described. You shouldn't miss any with your regular expression.

http://en.wikipedia.org/wiki/Uuid#Definition

You can just do this:

git remote add origin ssh://user@host:1234/srv/git/example

1234 is the ssh port being used

Set item using data['id'] = ....

import json

with open('data.json', 'r+') as f:
    data = json.load(f)
    data['id'] = 134 # <--- add `id` value.
    f.seek(0)        # <--- should reset file position to the beginning.
    json.dump(data, f, indent=4)
    f.truncate()     # remove remaining part

There was once an example in the SSL source in the directory demos/ssl/ with example code in C++. Now it's available only via the history: https://github.com/openssl/openssl/tree/691064c47fd6a7d11189df00a0d1b94d8051cbe0/demos/ssl

You probably will have to find a working version, I originally posted this answer at Nov 6 2015. And I had to edit the source -- not much.

$popover = $el.popover({
  html: true
  placement: 'left'

  trigger: 'manual'
  container: $container // to contain the popup code

The file /tmp/mysql.sock is probably a Named-Pipe, since it's in a temporary folder. A named pipe is a Special-File that never gets permanently stored.

If we make two programs, and we want one program to send a message to another program, we could create a text file. We have one program write something in the text file and the other program read what our other program wrote. That's what a pipe is, except it doesn't write the file to our computer hard disk, IE doesn't permanently store the file (like we do when we create a file and save it.)

A Socket is the exact same as a Pipe. The difference is that Sockets are usually used over a network -- between computers. A Socket sends information to another computer, or receives information from another computer. Both Pipes and Sockets use a temporary file to share so that they can 'communicate'.

It's difficult to discern which one MySql is using in this case. Doesn't matter though.

The command mysql.server start should get the 'server' (program) running its infinite loop that will create that special-file and wait for changes (listen for writes).

After that, a common issue might be that the MySql program doesn't have permission to create a file on your machine, so you might have to give it root privileges

sudo mysql.server start

Use the pdfpages package.

\usepackage{pdfpages}

To include all the pages in the PDF file:

\includepdf[pages=-]{myfile.pdf}

To include just the first page of a PDF:

\includepdf[pages={1}]{myfile.pdf}

Run texdoc pdfpages in a shell to see the complete manual for pdfpages.

"Segmentation fault" means that you tried to access memory that you do not have access to.

The first problem is with your arguments of main. The main function should be int main(int argc, char *argv[]), and you should check that argc is at least 2 before accessing argv[1].

Also, since you're passing in a float to printf (which, by the way, gets converted to a double when passing to printf), you should use the %f format specifier. The %s format specifier is for strings ('\0'-terminated character arrays).

From the Intel Instructions

"The SDK Manager will download the installer to the "extras" directory, under the main SDK directory. Even though the SDK manager says "Installed" it actually means that the Intel HAXM executable was downloaded. You will still need to run the installer from the "extras" directory to finish installation.

Extract the installer inside the "extras" directory and follow the installation instructions for your platform."

You can use the below C# Method to generate the insert scripts using Excel sheet just you need import OfficeOpenXml Package from NuGet Package Manager before executing the method.

public string GenerateSQLInsertScripts() {

        var outputQuery = new StringBuilder();
        var tableName = "Your Table Name";
        if (file != null)
        {
            var filePath = @"D:\FileName.xsls";

            using (OfficeOpenXml.ExcelPackage xlPackage = new OfficeOpenXml.ExcelPackage(new FileInfo(filePath)))
            {
                var myWorksheet = xlPackage.Workbook.Worksheets.First(); //select the first sheet here
                var totalRows = myWorksheet.Dimension.End.Row;
                var totalColumns = myWorksheet.Dimension.End.Column;

                var columns = new StringBuilder(); //this is your columns

                var columnRows = myWorksheet.Cells[1, 1, 1, totalColumns].Select(c => c.Value == null ? string.Empty : c.Value.ToString());

                columns.Append("INSERT INTO["+ tableName +"] (");
                foreach (var colrow in columnRows)
                {
                    columns.Append("[");
                    columns.Append(colrow);
                    columns.Append("]");
                    columns.Append(",");
                }
                columns.Length--;
                columns.Append(") VALUES (");
                for (int rowNum = 2; rowNum <= totalRows; rowNum++) //selet starting row here
                {
                    var dataRows = myWorksheet.Cells[rowNum, 1, rowNum, totalColumns].Select(c => c.Value == null ? string.Empty : c.Value.ToString());

                    var finalQuery = new StringBuilder(); 
                    finalQuery.Append(columns);

                    foreach (var dataRow in dataRows)
                    {
                        finalQuery.Append("'");
                        finalQuery.Append(dataRow);
                        finalQuery.Append("'");
                        finalQuery.Append(",");
                    }
                    finalQuery.Length--;

                    finalQuery.Append(");");

                    outputQuery.Append(finalQuery);

                  }

            }
        }

return outputQuery.ToString();}

To overwrite one file's content to another file. use cat eg.

echo  "this is foo" > foobar.txt
cat foobar.txt

echo "this is bar" > bar.txt
cat bar.txt

Now to overwrite foobar we can use a cat command as below

cat bar.txt >> foobar.txt
cat foobar.txt

Suppose https://www.mozilla.org/foo.html executes the following JavaScript:

const stateObj = { foo: 'bar' };

history.pushState(stateObj, '', 'bar.html');

This will cause the URL bar to display https://www.mozilla.org/bar2.html, but won't cause the browser to load bar2.html or even check that bar2.html exists.

Not sure if that's exactly what you need, but we are using profiles to define the environment we are running at and specific bean for each environment, so it's something like that:

<bean name="myBean" class="myClass">
    <constructor-arg name="name" value="originalValue" />
</bean>
<beans profile="DEV, default">
     <!-- Specific DEV configurations, also default if no profile defined -->
    <bean name="myBean" class="myClass">
        <constructor-arg name="name" value="overrideValue" />
    </bean>
</beans>
<beans profile="CI, UAT">
     <!-- Specific CI / UAT configurations -->
</beans>
<beans profile="PROD">
     <!-- Specific PROD configurations -->
</beans>

So in this case, if I don't define a profile or if I define it as "DEV" myBean will get "overrideValue" for it's name argument. But if I set the profile to "CI", "UAT" or "PROD" it will get "originalValue" as the value.

I don't understand why there are so many long explanations about this. All you have to do is install the pyreadline package with:

pip install pyreadline

sudo  port install py-readline (on Mac)

(Assuming you have already installed PIP.)

Just access the element and append it to the value.

<input
     type="button" 
     onclick="document.getElementById('myTextArea').value += '•'" 
     value="Add •">

See a live demo.

For the sake of keeping things simple, I haven't written unobtrusive JS. For a production system you should.

Also it needs to be a UTF8 character.

Browsers generally submit forms using the encoding they received the page in. Serve your page as UTF-8 if you want UTF-8 data submitted back.

I use this git alias:

git config --global alias.cam '!git commit -a -m '

So, instead of call

git add -A && git commit -m "this is a great commit"

I just do:

git cam "this is a great commit"

In my case, I found that a computed column had been added to the "included columns" of an index. Later, when an item in that table was updated, the merge statement failed with that message. The merge was in a trigger, so this was hard to track down! Removing the computed column from the index fixed it.

use this code

   private ClipboardManager myClipboard;
   private ClipData myClip;
   TextView textView;
   Button copyText;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mainpage);
    textView = (TextView) findViewById(R.id.textview);
    copyText = (Button) findViewById(R.id.bCopy);
    myClipboard = (ClipboardManager)getSystemService(CLIPBOARD_SERVICE);

    copyText.setOnClickListener(new View.OnClickListener() {


        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub


           String text = textView.getText().toString();
           myClip = ClipData.newPlainText("text", text);
           myClipboard.setPrimaryClip(myClip);
           Toast.makeText(getApplicationContext(), "Text Copied", 
           Toast.LENGTH_SHORT).show(); 
        }
    });
}

With PostgreSQL there are a number of date/time functions available, see here.

In your example, you could use:

SELECT * FROM myTable WHERE date_trunc('day', dt) = 'YYYY-MM-DD';

If you are running this query regularly, it is possible to create an index using the date_trunc function as well:

CREATE INDEX date_trunc_dt_idx ON myTable ( date_trunc('day', dt) );

One advantage of this is there is some more flexibility with timezones if required, for example:

CREATE INDEX date_trunc_dt_idx ON myTable ( date_trunc('day', dt at time zone 'Australia/Sydney') );
SELECT * FROM myTable WHERE date_trunc('day', dt at time zone 'Australia/Sydney') = 'YYYY-MM-DD';

When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.

With Basic Auth, the HTTP request from the question will look something like this:

GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk

The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password).

To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl, the username and password will be clearly visible on the process list and might turn up in the bash history file.

When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.

Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.

When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.

Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.

Maybe :active over :focus with :hover will help! Try

button {
background:lime;
}

button:hover {
background:green;
}

button:focus {
background:gray;
}

button:active {
background:red;
}

Then:

<button onkeydown="alerted_of_key_pressed()" id="button" title="Test button" href="#button">Demo</button>

Then:

<!--JAVASCRIPT-->
<script>
function alerted_of_key_pressed() { alert("You pressed a key when hovering over this button.") }
</script>

 Sorry about that last one. :) I was just showing you a cool function! 
Wait... did I just emphasize a code block? This is cool!!!

You can't remove keyword case. But your example can be written shorter like this:

switch ((Answer - 1) / 4)                                      
{
   case 0:
      cout << "You need more cars.";
      break;                                        
   case 1:
      cout << "Now you need a house.";
      break;                                        
   default:
      cout << "What are you? A peace-loving hippie freak?";
}

This is the better solution:

verify(mock_contractsDao, times(1)).save(Mockito.eq("Parameter I'm expecting"));

Have you tried logging in as the jenkins user?

Try this:

sudo -i -u jenkins #For RedHat you might have to do 'su' instead.
git clone [email protected]:your/repo.git

Often times you see failure if the host has not been added or authorized (hence I always manually login as hudson/jenkins for the first connection to github/bitbucket) but that link you included supposedly fixes that.

If the above doesn't work try recopying the key. Make sure its the pub key (ie id_rsa.pub). Maybe you missed some characters?

There's an extention to FPDF called UFDPF http://acko.net/blog/ufpdf-unicode-utf-8-extension-for-fpdf/

But, imho, it's better to use mpdf if you're it's possible for you to change class.

Use @ViewChild to reset your control.

Template:

<input mdInput placeholder="Name" #filterName name="filterName" >

In Code:

@ViewChild('filterName') redel:ElementRef;

then you can access your control as

this.redel= "";

You can add position: fixed; with top left right bottom 0 attribute, that solution work on older browsers too.

If you want to embed it, add position: absolute; to the wrapper, and position: relative to the div outside of the wrapper.

In most cases, it is enough just to hide the element, for example in this way:

export default class ErrorBoxComponent extends React.Component {
    constructor(props) {
        super(props);

        this.state = {
            isHidden: false
        }
    }

    dismiss() {
        this.setState({
            isHidden: true
        })
    }

    render() {
        if (!this.props.error) {
            return null;
        }

        return (
            <div data-alert className={ "alert-box error-box " + (this.state.isHidden ? 'DISPLAY-NONE-CLASS' : '') }>
                { this.props.error }
                <a href="#" className="close" onClick={ this.dismiss.bind(this) }>&times;</a>
            </div>
        );
    }
}

Or you may render/rerender/not render via parent component like this

export default class ParentComponent extends React.Component {
    constructor(props) {
        super(props);

        this.state = {
            isErrorShown: true
        }
    }

    dismiss() {
        this.setState({
            isErrorShown: false
        })
    }

    showError() {
        if (this.state.isErrorShown) {
            return <ErrorBox 
                error={ this.state.error }
                dismiss={ this.dismiss.bind(this) }
            />
        }

        return null;
    }

    render() {

        return (
            <div>
                { this.showError() }
            </div>
        );
    }
}

export default class ErrorBoxComponent extends React.Component {
    dismiss() {
        this.props.dismiss();
    }

    render() {
        if (!this.props.error) {
            return null;
        }

        return (
            <div data-alert className="alert-box error-box">
                { this.props.error }
                <a href="#" className="close" onClick={ this.dismiss.bind(this) }>&times;</a>
            </div>
        );
    }
}

Finally, there is a way to remove html node, but i really dont know is it a good idea. Maybe someone who knows React from internal will say something about this.

export default class ErrorBoxComponent extends React.Component {
    dismiss() {
        this.el.remove();
    }

    render() {
        if (!this.props.error) {
            return null;
        }

        return (
            <div data-alert className="alert-box error-box" ref={ (el) => { this.el = el} }>
                { this.props.error }
                <a href="#" className="close" onClick={ this.dismiss.bind(this) }>&times;</a>
            </div>
        );
    }
}

Math.Pow() returns double so nice would be to write like this:

double d = Math.Pow(100.00, 3.00);

Try following these steps:

1. Run Chrome as Administrator.
2. Go to the settings in Chrome.
3. Go to Advanced Settings (its all the way down).
4. Scroll to Network Section and click on ''Change proxy settings''.
5. A window will pop up with the name ''Internet Properties''
6. Click on ''LAN settings''
7. Un-check ''Use a proxy server for your LAN''
8. Check ''Automatically detect settings''
9. Click everything ''OK'' and you are done!

JavaScript Code

   //this function is used to fire click event
    function eventFire(el, etype){
      if (el.fireEvent) {
        el.fireEvent('on' + etype);
      } else {
        var evObj = document.createEvent('Events');
        evObj.initEvent(etype, true, false);
        el.dispatchEvent(evObj);
      }
    }

function showPdf(){
  eventFire(document.getElementById('picToClick'), 'click');
}

HTML Code

<img id="picToClick" data-toggle="modal" data-target="#pdfModal" src="img/Adobe-icon.png" ng-hide="1===1">
  <button onclick="showPdf()">Click me</button>

Use cut. Eg. to strip the first 4 characters of each line (i.e. start on the 5th char):

tail -f logfile | grep org.springframework | cut -c 5-

This is the easiest way to do this.

fin = open("a.txt")
f = open("file.txt", "wt")
for line in fin:
    f.write( line.replace('foo', 'bar') )
fin.close()
f.close()

I hope it will work for you.

So we are all doing the same home work?

Strange how the most up-voted answer is wrong. Remember, draw/fillOval take height and width as parameters, not the radius. So to correctly draw and center a circle with user-provided x, y, and radius values you would do something like this:

public static void drawCircle(Graphics g, int x, int y, int radius) {

  int diameter = radius * 2;

  //shift x and y by the radius of the circle in order to correctly center it
  g.fillOval(x - radius, y - radius, diameter, diameter); 

}

I was using python interpolation and forgot the ending s character:

a = dict(foo='bar')
print("What comes after foo? %(foo)" % a) # Should be %(foo)s

Watch those typos.

Just for fun, I'm going to use a single event on the whole document instead of adding an event to all the anchor tags:

document.body.onclick = function( e ) {
    // Cross-browser handling
    var evt = e || window.event,
        target = evt.target || evt.srcElement;

    // If the element clicked is an anchor
    if ( target.nodeName === 'A' ) {

        // Add the confirm box
        return confirm( 'Are you sure?' );
    }
};

This method would be more efficient if you had many anchor tags. Of course, it becomes even more efficient when you add this event to the container having all the anchor tags.

A simple way around it is just try changing the order of your imported jar files which can be done from (Eclipse). Right click on your package -> Build Path -> Configure build path -> References and Libraries -> Order and Export. Try changing the order of jars which contain signature files.

Update October 2016: Easiest now: use lvh.me which always points to 127.0.0.1.

Previous Answer:

Since the callback request is issued by the browser, as a HTTP redirect response, you can set up your .hosts file or equivalent to point a domain that is not localhost to 127.0.0.1.

Say for example you register the following callback with Twitter: http://www.publicdomain.com/callback/. Make sure that www.publicdomain.com points to 127.0.0.1 in your hosts file, AND that twitter can do a successful DNS lookup on www.publicdomain.com, i.e the domain needs to exist and the specific callback should probably return a 200 status message if requested.

EDIT:

I just read the following article: http://www.tonyamoyal.com/2009/08/17/how-to-quickly-set-up-a-test-for-twitter-oauth-authentication-from-your-local-machine, which was linked to from this question: Twitter oAuth callbackUrl - localhost development.

To quote the article:

You can use bit.ly, a URL shortening service. Just shorten the [localhost URL such as http//localhost:8080/twitter_callback] and register the shortened URL as the callback in your Twitter app.

This should be easier than fiddling around in the .hosts file.

Note that now (Aug '14) bit.ly is not allowing link forwarding to localhost; however Google link shortener works.

PS edit: (Nov '18): Google link shortener stopped giving support for localhost or 127.0.0.1.

Use a list instead and replace your foreach loop with a for loop:

@model IList<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()

    @for (var i = 0; i < Model.Count; i++) 
    {
        <tr>
            <td>
                @Html.HiddenFor(x => x[i].IP)           
                @Html.CheckBoxFor(x => x[i].Checked)
            </td>
            <td>
                @Html.DisplayFor(x => x[i].IP)
            </td>
        </tr>
    }
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

Alternatively you could use an editor template:

@model IEnumerable<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()
    @Html.EditorForModel()   
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

and then define the template ~/Views/Shared/EditorTemplates/BlockedIPViewModel.cshtml which will automatically be rendered for each element of the collection:

@model BlockedIPViewModel
<tr>
    <td>
        @Html.HiddenFor(x => x.IP)
        @Html.CheckBoxFor(x => x.Checked)
    </td>
    <td>
        @Html.DisplayFor(x => x.IP)
    </td>
</tr>

The reason you were getting null in your controller is because you didn't respect the naming convention for your input fields that the default model binder expects to successfully bind to a list. I invite you to read the following article.

Once you have read it, look at the generated HTML (and more specifically the names of the input fields) with my example and yours. Then compare and you will understand why yours doesn't work.

A decimal type can not contain formatting information. You can create another property, say FormattedProperty of a string type that does what you want.

I wrote a Tester class which can test the performance:

public class Tester
{
    public static void main(String[] args)
    {
        String text = "";

        int loopCount = 10000000;
        long startTime, endTime, duration1, duration2;

        startTime = System.nanoTime();
        for (int i = 0; i < loopCount; i++) {
            text.equals("");
        }
        endTime = System.nanoTime();
        duration1 = endTime - startTime;
        System.out.println(".equals(\"\") duration " +": \t" + duration1);

        startTime = System.nanoTime();
        for (int i = 0; i < loopCount; i++) {
            text.isEmpty();
        }
        endTime = System.nanoTime();
        duration2 = endTime - startTime;
        System.out.println(".isEmpty() duration "+": \t\t" + duration2);

        System.out.println("isEmpty() to equals(\"\") ratio: " + ((float)duration2 / (float)duration1));
    }
}

I found that using .isEmpty() took around half the time of .equals("").

Yeah, you can do it. Just open Settings -> Live Templates. Create new one with syso as abbreviation and System.out.println($END$); as Template text.

Had similar problems recently. Would suggest you carefully check if the user you're connecting with has proper authorizations on the remote machine.

You can review permissions using the following command.

Set-PSSessionConfiguration -ShowSecurityDescriptorUI -Name Microsoft.PowerShell

Found this tip here (updated link, thanks "unbob"):

https://devblogs.microsoft.com/scripting/configure-remote-security-settings-for-windows-powershell/

It fixed it for me.

update your CSS to the following: this should fix

.page {
    width: 280px;
    border:solid 1px blue;
    overflow-x: auto;
}

you can use tcpdump on the server to check if the client even reaches the server.

  tcpdump -i any tcp port 9100

also make sure your firewall is not blocking incoming connections.

EDIT: you can also write the dump into a file and view it with wireshark on your client if you don't want to read it on the console.

2nd Edit: you can check if you can reach the port via

 nc ip 9100 -z -v

from your local PC.

esModuleInterop generates the helpers outlined in the docs. Looking at the generated code, we can see exactly what these do:

//ts 
import React from 'react'
//js 
var __importDefault = (this && this.__importDefault) || function (mod) {
    return (mod && mod.__esModule) ? mod : { "default": mod };
};
Object.defineProperty(exports, "__esModule", { value: true });
var react_1 = __importDefault(require("react"));

__importDefault: If the module is not an es module then what is returned by require becomes the default. This means that if you use default import on a commonjs module, the whole module is actually the default.

__importStar is best described in this PR:

TypeScript treats a namespace import (i.e. import * as foo from "foo") as equivalent to const foo = require("foo"). Things are simple here, but they don't work out if the primary object being imported is a primitive or a value with call/construct signatures. ECMAScript basically says a namespace record is a plain object.

Babel first requires in the module, and checks for a property named __esModule. If __esModule is set to true, then the behavior is the same as that of TypeScript, but otherwise, it synthesizes a namespace record where:

1. All properties are plucked off of the require'd module and made available as named imports.
2. The originally require'd module is made available as a default import.

So we get this:

// ts
import * as React from 'react'

// emitted js
var __importStar = (this && this.__importStar) || function (mod) {
    if (mod && mod.__esModule) return mod;
    var result = {};
    if (mod != null) for (var k in mod) if (Object.hasOwnProperty.call(mod, k)) result[k] = mod[k];
    result["default"] = mod;
    return result;
};
Object.defineProperty(exports, "__esModule", { value: true });
var React = __importStar(require("react"));

allowSyntheticDefaultImports is the companion to all of this, setting this to false will not change the emitted helpers (both of them will still look the same). But it will raise a typescript error if you are using default import for a commonjs module. So this import React from 'react' will raise the error Module '".../node_modules/@types/react/index"' has no default export. if allowSyntheticDefaultImports is false.

I just answered a similar question here IMHO, if your FTP server is able to communicate with Fabric please us Fabric. It is far better than doing raw ftp.

I have an FTP account from dotgeek.com so I am not sure if this will work for other FTP accounts.

#!/usr/bin/python

from fabric.api import run, env, sudo, put

env.user = 'username'
env.hosts = ['ftp_host_name',]     # such as ftp.google.com

def copy():
    # assuming i have wong_8066.zip in the same directory as this script
    put('wong_8066.zip', '/www/public/wong_8066.zip')

save the file as fabfile.py and run fab copy locally.

yeukhon@yeukhon-P5E-VM-DO:~$ fab copy2
[1.ai] Executing task 'copy2'
[1.ai] Login password: 
[1.ai] put: wong_8066.zip -> /www/public/wong_8066.zip

Done.
Disconnecting from 1.ai... done.

Once again, if you don't want to input password all the time, just add

env.password = 'my_password'

In fact, xargs can run commands in parallel for you. There is a special -P max_procs command-line option for that. See man xargs.

By all your powers combined I use this helper class for reading resources from any assembly and any namespace in a generic way.

public class ResourceReader
{
    public static IEnumerable<string> FindEmbededResources<TAssembly>(Func<string, bool> predicate)
    {
        if (predicate == null) throw new ArgumentNullException(nameof(predicate));

        return
            GetEmbededResourceNames<TAssembly>()
                .Where(predicate)
                .Select(name => ReadEmbededResource(typeof(TAssembly), name))
                .Where(x => !string.IsNullOrEmpty(x));
    }

    public static IEnumerable<string> GetEmbededResourceNames<TAssembly>()
    {
        var assembly = Assembly.GetAssembly(typeof(TAssembly));
        return assembly.GetManifestResourceNames();
    }

    public static string ReadEmbededResource<TAssembly, TNamespace>(string name)
    {
        if (string.IsNullOrEmpty(name)) throw new ArgumentNullException(nameof(name));
        return ReadEmbededResource(typeof(TAssembly), typeof(TNamespace), name);
    }

    public static string ReadEmbededResource(Type assemblyType, Type namespaceType, string name)
    {
        if (assemblyType == null) throw new ArgumentNullException(nameof(assemblyType));
        if (namespaceType == null) throw new ArgumentNullException(nameof(namespaceType));
        if (string.IsNullOrEmpty(name)) throw new ArgumentNullException(nameof(name));

        return ReadEmbededResource(assemblyType, $"{namespaceType.Namespace}.{name}");
    }

    public static string ReadEmbededResource(Type assemblyType, string name)
    {
        if (assemblyType == null) throw new ArgumentNullException(nameof(assemblyType));
        if (string.IsNullOrEmpty(name)) throw new ArgumentNullException(nameof(name));

        var assembly = Assembly.GetAssembly(assemblyType);
        using (var resourceStream = assembly.GetManifestResourceStream(name))
        {
            if (resourceStream == null) return null;
            using (var streamReader = new StreamReader(resourceStream))
            {
                return streamReader.ReadToEnd();
            }
        }
    }
}

If you're open to changing the original string, you can simply replace the delimiter with \0. The original pointer will point to the first string and the pointer to the character after the delimiter will point to the second string. The good thing is you can use both pointers at the same time without allocating any new string buffers.

var data = 'id='+ id  & 'name='+ name;

The ampersand needs to be quoted as well:

var data = 'id='+ id  + '&name='+ name;

Thats how I handle it

 while(true) {
        if((receiveMessage = receiveRead.readLine()) != null ) {  

        System.out.println("first message same :"+receiveMessage);
        System.out.println(receiveMessage);      

        }
        else if(receiveRead.readLine()==null)
        {

        System.out.println("Client has disconected: "+sock.isClosed()); 
        System.exit(1);
         }    } 

if the result.code == null

you can also put labels inside plot:

plot(spline(sub$day, sub$counts), type ='l', labels = FALSE)

you'll get a warning. i think this is because labels is actually a parameter that's being passed down to a subroutine that plot runs (axes?). the warning will pop up because it wasn't directly a parameter of the plot function.

The flask project structure is different. As you mentioned in question the project structure is the same but the only problem is wit the styles folder. Styles folder must come within the static folder.

static/styles/style.css

The easy way is by using sprintf. I know others have suggested itoa, but a) it isn't part of the standard library, and b) sprintf gives you formatting options that itoa doesn't.

$ if [ "$s1" == "$s2" ]; then echo match; fi
match
$ test "s1" = "s2" ;echo match
match
$

HTML:

First, we will need to add a class to your text container so that we can access and style it accordingly.

<div class="col-xs-5 textContainer">
     <h3 class="text-left">Link up with other gamers all over the world who share the same tastes in games.</h3>
</div>

CSS:

Next, we will apply the following styles to align it vertically, according to the size of the image div next to it.

.textContainer { 
    height: 345px; 
    line-height: 340px;
}

.textContainer h3 {
    vertical-align: middle;
    display: inline-block;
}

All Done! Adjust the line-height and height on the styles above if you believe that it is still slightly out of align.

WORKING EXAMPLE

Update: This answer is very old. gridExtra::grid.arrange() is now the recommended approach. I leave this here in case it might be useful.

Stephen Turner posted the arrange() function on Getting Genetics Done blog (see post for application instructions)

vp.layout <- function(x, y) viewport(layout.pos.row=x, layout.pos.col=y)
arrange <- function(..., nrow=NULL, ncol=NULL, as.table=FALSE) {
 dots <- list(...)
 n <- length(dots)
 if(is.null(nrow) & is.null(ncol)) { nrow = floor(n/2) ; ncol = ceiling(n/nrow)}
 if(is.null(nrow)) { nrow = ceiling(n/ncol)}
 if(is.null(ncol)) { ncol = ceiling(n/nrow)}
        ## NOTE see n2mfrow in grDevices for possible alternative
grid.newpage()
pushViewport(viewport(layout=grid.layout(nrow,ncol) ) )
 ii.p <- 1
 for(ii.row in seq(1, nrow)){
 ii.table.row <- ii.row 
 if(as.table) {ii.table.row <- nrow - ii.table.row + 1}
  for(ii.col in seq(1, ncol)){
   ii.table <- ii.p
   if(ii.p > n) break
   print(dots[[ii.table]], vp=vp.layout(ii.table.row, ii.col))
   ii.p <- ii.p + 1
  }
 }
}

You could try this.

In windows go to Administrative Tools->Services And see scroll down to where it says Oracle[instanceNameHere] and see if the listener and the service itself are running. You might have to start it. You can also set it to start automatically when you right-click on it and go to properties.

Just go to your tsconfig.app.json in your project and remove all from it

and copy below code and paste it. It will solve your issue :)

Setting the CurrentCell and then calling BeginEdit(true) works well for me.

The following code shows an eventHandler for the KeyDown event that sets a cell to be editable.

My example only implements one of the required key press overrides but in theory the others should work the same. (and I'm always setting the [0][0] cell to be editable but any other cell should work)

    private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Tab && dataGridView1.CurrentCell.ColumnIndex == 1)
        {
            e.Handled = true;
            DataGridViewCell cell = dataGridView1.Rows[0].Cells[0];
            dataGridView1.CurrentCell = cell;
            dataGridView1.BeginEdit(true);               
        }
    }

If you haven't found it previously, the DataGridView FAQ is a great resource, written by the program manager for the DataGridView control, which covers most of what you could want to do with the control.

Since Trung Le Nguyen Nhat's fiddle isn't correct at all (it just uses the original image in the last step)
I wrote my own general fiddle with performance comparison:

FIDDLE

Basically it's:

img.onload = function() {
   var canvas = document.createElement('canvas'),
       ctx = canvas.getContext("2d"),
       oc = document.createElement('canvas'),
       octx = oc.getContext('2d');

   canvas.width = width; // destination canvas size
   canvas.height = canvas.width * img.height / img.width;

   var cur = {
     width: Math.floor(img.width * 0.5),
     height: Math.floor(img.height * 0.5)
   }

   oc.width = cur.width;

You should convert charset after decoding: convert(base64_decode(base64_encode('????')) using utf8)

Architecture is the resulting collection of design patterns to build a system.

I guess Design is the creativity used to put all this together?

Here is another way:

df[[i for i in list(df.columns) if i != '<your column>']]

You just pass all columns to be shown except of the one you do not want.

I have an example I would like to share

$File = "C:\Foo.txt"
#retrieves the Systems current Date and Time in a DateTime Format
$today = Get-Date
#subtracts 12 hours from the date to ensure the file has been written to recently
$today = $today.AddHours(-12)
#gets the last time the $file was written in a DateTime Format
$lastWriteTime = (Get-Item $File).LastWriteTime

#If $File doesn't exist we will loop indefinetely until it does exist.
# also loops until the $File that exists was written to in the last twelve hours
while((!(Test-Path $File)) -or ($lastWriteTime -lt $today))
{
    #if a file exists then the write time is wrong so update it
    if (Test-Path $File)
    {
        $lastWriteTime = (Get-Item $File).LastWriteTime
    }
    #Sleep for 5 minutes
    $time = Get-Date
    Write-Host "Sleep" $time
    Start-Sleep -s 300;
}

From Wikipedia:

The final '==' sequence indicates that the last group contained only one byte, and '=' indicates that it contained two bytes.

Thus, this is some sort of padding.

May I present my guess, since this is not a open technology.

Google says it's about combing information from before, during, after to distinguish human from robot. But I am more interested about that final click on the check box.

Say, the POST data (solved CAPTCHA) has a field called fingerprint, a string calculated from user behavior. I think there may be a field about that check box location. I guess this check box is in a coordinate system randomly generated by Google back-end and encrypted by the public key of my site. So, a robot may "guess/calculate" a location about this box, but when site owner makes the GET query with private key to verify user identity, Google will decrypt the coordinate system and say if the user click on the right place. So, only one possible right click(with some offsets, it's a square box) location in this random coordinate system owned by only Google and site owners.

While I know the intent behind strncpy, it is not really a good function. Avoid both. Raymond Chen explains.

Personally, my conclusion is simply to avoid strncpy and all its friends if you are dealing with null-terminated strings. Despite the "str" in the name, these functions do not produce null-terminated strings. They convert a null-terminated string into a raw character buffer. Using them where a null-terminated string is expected as the second buffer is plain wrong. Not only do you fail to get proper null termination if the source is too long, but if the source is short you get unnecessary null padding.

See also Why is strncpy insecure?

Well, there's always the brute force method:

<li><pre>    The lazy dog.</pre></li>
<li><pre>AND The lazy cat.</pre></li>
<li><pre>OR  The active goldfish.</pre></li>

Or is that what you meant by "padding" the text? That's an ambiguous work in this context.

This sounds kind of like a homework question. I hope you're not trying to get us to do your homework for you?

You can improve read speed by using a BufferedStream, like this:

using (FileStream fs = File.Open(path, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
using (BufferedStream bs = new BufferedStream(fs))
using (StreamReader sr = new StreamReader(bs))
{
    string line;
    while ((line = sr.ReadLine()) != null)
    {

    }
}

March 2013 UPDATE

I recently wrote code for reading and processing (searching for text in) 1 GB-ish text files (much larger than the files involved here) and achieved a significant performance gain by using a producer/consumer pattern. The producer task read in lines of text using the BufferedStream and handed them off to a separate consumer task that did the searching.

I used this as an opportunity to learn TPL Dataflow, which is very well suited for quickly coding this pattern.

Why BufferedStream is faster

A buffer is a block of bytes in memory used to cache data, thereby reducing the number of calls to the operating system. Buffers improve read and write performance. A buffer can be used for either reading or writing, but never both simultaneously. The Read and Write methods of BufferedStream automatically maintain the buffer.

December 2014 UPDATE: Your Mileage May Vary

Based on the comments, FileStream should be using a BufferedStream internally. At the time this answer was first provided, I measured a significant performance boost by adding a BufferedStream. At the time I was targeting .NET 3.x on a 32-bit platform. Today, targeting .NET 4.5 on a 64-bit platform, I do not see any improvement.

I came across a case where streaming a large, generated CSV file to the Response stream from an ASP.Net MVC action was very slow. Adding a BufferedStream improved performance by 100x in this instance. For more see Unbuffered Output Very Slow

You might want to look into the DirectoryInfo.Parent property.

In my case was it was very wired! Besides adding a correct proxy (I'm working within a company), I needed to add the other two libraries in the dependencies:

compile 'com.android.support:appcompat-v7:25.0.1'
compile 'com.android.support:design:25.0.1'

then the error for "junit:junit:4.12" was resolved. Make sure that all of the dependencies in build.gradle match what you import in project structure

What you want is actually possible now. If you can run the asynchronous code in a service worker, and the synchronous code in a web worker, then you can have the web worker send a synchronous XHR to the service worker, and while the service worker does the async things, the web worker's thread will wait. This is not a great approach, but it could work.

You probably mean heap memory, not memory heap.

Heap memory is essentially a large pool of memory (typically per process) from which the running program can request chunks. This is typically called dynamic allocation.

It is different from the Stack, where "automatic variables" are allocated. So, for example, when you define in a C function a pointer variable, enough space to hold a memory address is allocated on the stack. However, you will often need to dynamically allocate space (With malloc) on the heap and then provide the address where this memory chunk starts to the pointer.

DECIMAL has two parts: Precision and Scale. So part of your query will look like this:

CAST((COUNT(*) * 1.5) AS DECIMAL(8,2))

Precision represents the number of significant digits that are stored for values.
Scale represents the number of digits that can be stored following the decimal point.
