Here is an answer for those who compile from the command line/Command Prompt. It doesn't require changing your Path environment variable; it simply lets you use the 32-bit JVM for the program with the 32-bit DLL.

For the compilation, it shouldn't matter which javac gets used - 32-bit or 64-bit.

>javac MyProgramWith32BitNativeLib.java

For the actual execution of the program, it is important to specify the path to the 32-bit version of java.exe

I'll post a code example for Windows, since that seems to be the OS used by the OP.

Windows

Most likely, the code will be something like:

>"C:\Program Files (x86)\Java\jre#.#.#_###\bin\java.exe" MyProgramWith32BitNativeLib 

The difference will be in the numbers after jre. To find which numbers you should use, enter:

>dir "C:\Program Files (x86)\Java\"

On my machine, the process is as follows

C:\Users\me\MyProject>dir "C:\Program Files (x86)\Java"
 Volume in drive C is Windows
 Volume Serial Number is 0000-9999

 Directory of C:\Program Files (x86)\Java

11/03/2016  09:07 PM    <DIR>          .
11/03/2016  09:07 PM    <DIR>          ..
11/03/2016  09:07 PM    <DIR>          jre1.8.0_111
               0 File(s)              0 bytes
               3 Dir(s)  107,641,901,056 bytes free

C:\Users\me\MyProject>

So I know that my numbers are 1.8.0_111, and my command is

C:\Users\me\MyProject>"C:\Program Files (x86)\Java\jre1.8.0_111\bin\java.exe" MyProgramWith32BitNativeLib

installing Microsoft Visual C++ 2010 SP1 Redistributable Fixed it

In case you are on Ubuntu:

#X means 6,7,8...
apt install openjdk-X-jdk

Android Studio 2.2 came out with the ability to use ndk-build and cMake. Though, we had to wait til 2.2.3 for the Application.mk support. I've tried it, it works...though, my variables aren't showing up in the debugger. I can still query them via command line though.

You need to do something like this:

externalNativeBuild{
   ndkBuild{
        path "Android.mk"
    }
}

defaultConfig {
  externalNativeBuild{
    ndkBuild {
      arguments "NDK_APPLICATION_MK:=Application.mk"
      cFlags "-DTEST_C_FLAG1"  "-DTEST_C_FLAG2"
      cppFlags "-DTEST_CPP_FLAG2"  "-DTEST_CPP_FLAG2"
      abiFilters "armeabi-v7a", "armeabi"
    }
  } 
}

See http://tools.android.com/tech-docs/external-c-builds

NB: The extra nesting of externalNativeBuild inside defaultConfig was a breaking change introduced with Android Studio 2.2 Preview 5 (July 8, 2016). See the release notes at the above link.

As many folks already alluded to, this is a 32 vs. 64 bit problem for both Eclipse and Java. You cannot mix up 32 and 64 bit. Since Eclipse doesn't use JAVA_HOME, you'll likely have to alter your PATH prior to launching Eclipse to ensure you are using not only the appropriate version of Java, but also if 32 or 64 bit (or modify the INI file as Jayath noted).

If you are installing Eclipse from a company-share, you should ensure you can tell which Eclipse version you are unzipping, and unzip to the appropriate Program Files directory to help keep track of which is which, then change the PATH (either permanently via (Windows) Control Panel -> System or set PATH=/path/to/32 or 64bit/java/bin;%PATH% (maybe create a batch file if you don't want to set it in your system and/or user environment variables). Remember, 32-bit is in Program files (x86).

If unsure, just launch Eclipse, if you get the error, change your PATH to the other 'bit' version of Java, and then try again. Then move the Eclipse directory to the appropriate Program Files directory.

Installing a 64-bit version of Java will solve the issue. Go to page Java Downloads for All Operating Systems

This is a problem due to the incompatibility of the Java version and the Eclipse version both should be 64 bit if you are using a 64-bit system.

1. If you believe that you added a path of native lib to %PATH%, try testing with:

   System.out.println(System.getProperty("java.library.path"))
   

It should show you actually if your dll is on %PATH%

2. Restart the IDE Idea, which appeared to work for me after I setup the env variable by adding it to the %PATH%

Complementary info:

On a running process you may use (at least with some recent Sun JDK5/6 versions):

$ /opt/java1.5/bin/jinfo -sysprops 14680 | grep sun.arch.data.model
Attaching to process ID 14680, please wait...
Debugger attached successfully.
Server compiler detected.
JVM version is 1.5.0_16-b02
sun.arch.data.model = 32

where 14680 is PID of jvm running the application. "os.arch" works too.

Also other scenarios are supported:

jinfo [ option ] pid
jinfo [ option ] executable core
jinfo [ option ] [server-id@]remote-hostname-or-IP 

However consider also this note:

"NOTE - This utility is unsupported and may or may not be available in future versions of the JDK. In Windows Systems where dbgent.dll is not present, 'Debugging Tools for Windows' needs to be installed to have these tools working. Also the PATH environment variable should contain the location of jvm.dll used by the target process or the location from which the Crash Dump file was produced."

Thanks Jason Rogers's answer first.

In Android && cpp should be this:

const char *nativeString = env->GetStringUTFChars(javaString, nullptr);

// use your string

env->ReleaseStringUTFChars(javaString, nativeString);

Can fix this errors:

1.error: base operand of '->' has non-pointer type 'JNIEnv {aka _JNIEnv}'

2.error: no matching function for call to '_JNIEnv::GetStringUTFChars(JNIEnv*&, _jstring*&, bool)'

3.error: no matching function for call to '_JNIEnv::ReleaseStringUTFChars(JNIEnv*&, _jstring*&, char const*&)'

4.add "env->DeleteLocalRef(nativeString);" at end.

If it's an object method, you need to pass the object to CallObjectMethod:

jobject result = env->CallObjectMethod(obj, messageMe, jstr);

What you were doing was the equivalent of jstr.messageMe().

Since your is a void method, you should call:

env->CallVoidMethod(obj, messageMe, jstr);

If you want to return a result, you need to change your JNI signature (the ()V means a method of void return type) and also the return type in your Java code.

Do you realize, that CLAMP255 returns 0 for v < 0 and 255 for v >= 0?
IMHO, CLAMP255 should be defined as:

#define CLAMP255(v) (v > 255 ? 255 : (v < 0 ? 0 : v))

Difference: If v is not greater than 255 and not less than 0: return v instead of 255

From some where I found below :-

In fact, you can.

Using reflections API you can access any class so far. At least I was able to :)

Class fooClass = Class.forName("FooBar");
Method fooMethod =
    fooClass.getMethod("fooMethod", new Class[] { String.class });

String fooReturned =
    (String) fooMethod.invoke(fooClass.newInstance(), "I did it");

If the problem occurs while lanching an ANT, check your ANT HOME: it must point to the same eclipse folder you are running.

It happened to me while I reinstalled a new eclipse version and deleted previouis eclipse fodler while keeping the previous ant home: ant simply did not find any java library.

This in this case the reason is not a bad JDK version.

It marks a method, that it will be implemented in other languages, not in Java. It works together with JNI (Java Native Interface).

Native methods were used in the past to write performance critical sections but with Java getting faster this is now less common. Native methods are currently needed when

• You need to call a library from Java that is written in other language.

• You need to access system or hardware resources that are only reachable from the other language (typically C). Actually, many system functions that interact with real computer (disk and network IO, for instance) can only do this because they call native code.

See Also Java Native Interface Specification

Pyperclip seems to be up to the task.

You can use the -quit option of find:

find <dir> -maxdepth 1 -type d -name '*foo*' -print -quit

To insert a VARCHAR2 into a BLOB column you can rely on the function utl_raw.cast_to_raw as next:

insert into mytable(id, myblob) values (1, utl_raw.cast_to_raw('some magic here'));

It will cast your input VARCHAR2 into RAW datatype without modifying its content, then it will insert the result into your BLOB column.

More details about the function utl_raw.cast_to_raw

After messing about with some stuff in cron which wasn't instantly compatible I found that the following approach was nice for debugging:

crontab -e

* * * * * /path/to/prog var1 var2 &>>/tmp/cron_debug_log.log

This will run the task once a minute and you can simply look in the /tmp/cron_debug_log.log file to figure out what is going on.

It is not exactly the "fire job" you might be looking for, but this helped me a lot when debugging a script that didn't work in cron at first.

In sql 2012 (and maybe as far back as 2005), you should do this:

EXEC AddBrand @BrandName = 'Gucci', @CategoryId = 23

Leaving an answer for anyone looking to do something similar but in a horizontal direction, like I wanted to.

Tweaking @strider820's answer like below will do the magic:

.fixed-content {        //comments showing what I replaced.
    left:0;             //top: 0;
    right:0;            //bottom:0;
    position:fixed;
    overflow-y:hidden;  //overflow-y:scroll;
    overflow-x:auto;    //overflow-x:hidden;
}

That's it. Also check this comment where @train explained using overflow:auto over overflow:scroll.

It would be more helpful if you posed a more complete working (or in this case non-working) example.

I tried the following:

import numpy as np
import matplotlib.pyplot as plt

x = np.random.randn(1000)

fig = plt.figure()
ax = fig.add_subplot(111)
n, bins, rectangles = ax.hist(x, 50, density=True)
fig.canvas.draw()
plt.show()

This will indeed produce a bar-chart histogram with a y-axis that goes from [0,1].

Further, as per the hist documentation (i.e. ax.hist? from ipython), I think the sum is fine too:

*normed*:
If *True*, the first element of the return tuple will
be the counts normalized to form a probability density, i.e.,
``n/(len(x)*dbin)``.  In a probability density, the integral of
the histogram should be 1; you can verify that with a
trapezoidal integration of the probability density function::

    pdf, bins, patches = ax.hist(...)
    print np.sum(pdf * np.diff(bins))

Giving this a try after the commands above:

np.sum(n * np.diff(bins))

I get a return value of 1.0 as expected. Remember that normed=True doesn't mean that the sum of the value at each bar will be unity, but rather than the integral over the bars is unity. In my case np.sum(n) returned approx 7.2767.

Currently with swift 5 the easiest way to check if the player is playing or paused is to check the .timeControlStatus variable.

player.timeControlStatus == .paused
player.timeControlStatus == .playing

In Sqlite:

CREATE TABLE T AS
SELECT * FROM ...;

DROP TABLE T;

1. bind() of INADDR_ANY does NOT "generate a random IP". It binds the socket to all available interfaces.

2. For a server, you typically want to bind to all interfaces - not just "localhost".

3. If you wish to bind your socket to localhost only, the syntax would be my_sockaddress.sin_addr.s_addr = inet_addr("127.0.0.1");, then call bind(my_socket, (SOCKADDR *) &my_sockaddr, ...).

4. As it happens, INADDR_ANY is a constant that happens to equal "zero":

   http://www.castaglia.org/proftpd/doc/devel-guide/src/include/inet.h.html

   # define INADDR_ANY ((unsigned long int) 0x00000000)
   ...
   # define INADDR_NONE    0xffffffff
   ...
   # define INPORT_ANY 0
   ...
   

5. If you're not already familiar with it, I urge you to check out Beej's Guide to Sockets Programming:

   http://beej.us/guide/bgnet/

Since people are still reading this, an additional note:

man (7) ip:

When a process wants to receive new incoming packets or connections, it should bind a socket to a local interface address using bind(2).

In this case, only one IP socket may be bound to any given local (address, port) pair. When INADDR_ANY is specified in the bind call, the socket will be bound to all local interfaces.

When listen(2) is called on an unbound socket, the socket is automatically bound to a random free port with the local address set to INADDR_ANY.

When connect(2) is called on an unbound socket, the socket is automatically bound to a random free port or to a usable shared port with the local address set to INADDR_ANY...

There are several special addresses: INADDR_LOOPBACK (127.0.0.1) always refers to the local host via the loopback device; INADDR_ANY (0.0.0.0) means any address for binding...

Also:

bind() — Bind a name to a socket:

If the (sin_addr.s_addr) field is set to the constant INADDR_ANY, as defined in netinet/in.h, the caller is requesting that the socket be bound to all network interfaces on the host. Subsequently, UDP packets and TCP connections from all interfaces (which match the bound name) are routed to the application. This becomes important when a server offers a service to multiple networks. By leaving the address unspecified, the server can accept all UDP packets and TCP connection requests made for its port, regardless of the network interface on which the requests arrived.

Ended up to have a file named polyfill.js in projectpath\src\polyfill.js That file only contains this line: import 'core-js'; this polyfills not only es-6, but is the correct way to use core-js since version 3.0.0.

I added the polyfill.js to my webpack-file entry attribute like this:

entry: ['./src/main.scss', './src/polyfill.js', './src/main.jsx']

Works perfectly.

I also found some more information here : https://github.com/zloirock/core-js/issues/184

The library author (zloirock) claims:

ES6 changes behaviour almost all features added in ES5, so core-js/es6 entry point includes almost all of them. Also, as you wrote, it's required for fixing broken browser implementations.

(Quotation https://github.com/zloirock/core-js/issues/184 from zloirock)

So I think import 'core-js'; is just fine.

Use reduce() to convert the list to a single dict.

words = "apple banana apple strawberry banana lemon"
reduce( lambda d, c: d.update([(c, d.get(c,0)+1)]) or d, words.split(), {})

returns

{'strawberry': 1, 'lemon': 1, 'apple': 2, 'banana': 2}

This is a standard interview question:

Dynamic memory allocation

Is memory allocated at runtime using calloc(), malloc() and friends. It is sometimes also referred to as 'heap' memory, although it has nothing to do with the heap data-structure ^ref.

int * a = malloc(sizeof(int));

Heap memory is persistent until free() is called. In other words, you control the lifetime of the variable.

Automatic memory allocation

This is what is commonly known as 'stack' memory, and is allocated when you enter a new scope (usually when a new function is pushed on the call stack). Once you move out of the scope, the values of automatic memory addresses are undefined, and it is an error to access them.

int a = 43;

Note that scope does not necessarily mean function. Scopes can nest within a function, and the variable will be in-scope only within the block in which it was declared. Note also that where this memory is allocated is not specified. (On a sane system it will be on the stack, or registers for optimisation)

Static memory allocation

Is allocated at compile time^*, and the lifetime of a variable in static memory is the lifetime of the program.

In C, static memory can be allocated using the static keyword. The scope is the compilation unit only.

Things get more interesting when the extern keyword is considered. When an extern variable is defined the compiler allocates memory for it. When an extern variable is declared, the compiler requires that the variable be defined elsewhere. Failure to declare/define extern variables will cause linking problems, while failure to declare/define static variables will cause compilation problems.

in file scope, the static keyword is optional (outside of a function):

int a = 32;

But not in function scope (inside of a function):

static int a = 32;

Technically, extern and static are two separate classes of variables in C.

extern int a; /* Declaration */
int a; /* Definition */

^*Notes on static memory allocation

It's somewhat confusing to say that static memory is allocated at compile time, especially if we start considering that the compilation machine and the host machine might not be the same or might not even be on the same architecture.

It may be better to think that the allocation of static memory is handled by the compiler rather than allocated at compile time.

For example the compiler may create a large data section in the compiled binary and when the program is loaded in memory, the address within the data segment of the program will be used as the location of the allocated memory. This has the marked disadvantage of making the compiled binary very large if uses a lot of static memory. It's possible to write a multi-gigabytes binary generated from less than half a dozen lines of code. Another option is for the compiler to inject initialisation code that will allocate memory in some other way before the program is executed. This code will vary according to the target platform and OS. In practice, modern compilers use heuristics to decide which of these options to use. You can try this out yourself by writing a small C program that allocates a large static array of either 10k, 1m, 10m, 100m, 1G or 10G items. For many compilers, the binary size will keep growing linearly with the size of the array, and past a certain point, it will shrink again as the compiler uses another allocation strategy.

Register Memory

The last memory class are 'register' variables. As expected, register variables should be allocated on a CPU's register, but the decision is actually left to the compiler. You may not turn a register variable into a reference by using address-of.

register int meaning = 42;
printf("%p\n",&meaning); /* this is wrong and will fail at compile time. */

Most modern compilers are smarter than you at picking which variables should be put in registers :)

You can use nonzero function. it returns the nonzero indices of the given input.

Easy Way

>>> (e > 15).nonzero()

(array([1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2]), array([6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9]))

to see the indices more cleaner, use transpose method:

>>> numpy.transpose((e>15).nonzero())

[[1 6]
 [1 7]
 [1 8]
 [1 9]
 [2 0]
 ...

Not Bad Way

>>> numpy.nonzero(e > 15)

(array([1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2]), array([6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9]))

or the clean way:

>>> numpy.transpose(numpy.nonzero(e > 15))

[[1 6]
 [1 7]
 [1 8]
 [1 9]
 [2 0]
 ...

You could also replicate the C++ behaviour that you want very simply

public static boolean parseInt(String str, int[] byRef) {
    if(byRef==null) return false;
    try {
       byRef[0] = Integer.parseInt(prop);
       return true;
    } catch (NumberFormatException ex) {
       return false;
    }
}

You would use the method like so:

int[] byRef = new int[1];
boolean result = parseInt("123",byRef);

After that the variable result it's true if everything went allright and byRef[0] contains the parsed value.

Personally, I would stick to catching the exception.

There was some good code posted that solved the problem better than !a != !b

Note that I had to add the BOOL_DETAIL_OPEN/CLOSE so it would work on MSVC 2010

   But what is this funny "(( a bool_xor b ))"? Well, you can create some
   macros that allow you such a strange syntax. Note that the
   double-brackets are part of the syntax and cannot be removed! The set of
   three macros (plus two internal helper macros) also provides bool_and
   and bool_or. That given, what is it good for? We have && and || already,
   why do we need such a stupid syntax? Well, && and || can't guarantee
   that the arguments are converted to bool and that you get a bool result.
     Think "operator overloads". Here's how the macros look like:

    //OR

    System.IO.StreamReader reader = new System.IO.StreamReader(fileToOpen);
    //etc
}

The text before each parameter is part of the method name. From your example, the name of the method is actually

-getBusStops:forTime:

Each : represents an argument. In a method call, the method name is split at the :s and arguments appear after the :s. e.g.

[getBusStops: arg1 forTime: arg2]

Those stumbling with this on Visual Studio 2017: there is a feature related to CMake that needs to be selected and installed together with the relevant compiler toolsets. See the screenshot below.

You are doing integer arithmetic, so there the result is correct. Try

percentage=((double)number/total)*100;

BTW the %f expects a double not a float. By pure luck that is converted here, so it works out well. But generally you'd mostly use double as floating point type in C nowadays.

Here is what I look at everytime I am writing a new crontab entry:

To start editing from terminal -type:

 zee$ crontab -e

what you will add to crontab file:

0 22 * * 0  some-user /opt/somescript/to/run.sh

What it means:

[ 
+ user => 'some-user',      
+ minute => ‘0’,             <<= on top of the hour.
+ hour => '22',              <<= at 10 PM. Military time.
+ monthday => '*',           <<= Every day of the month*
+ month => '*',              <<= Every month*
+ weekday => ‘0’,            <<= Everyday (0 thru 6) = sunday thru saturday
] 

Also, check what shell your machine is running and name the the file accordingly OR it wont execute.

Check the shell with either echo $SHELL or echo $0

It can be "Bourne shell (sh) , Bourne again shell (bash),Korn shell (ksh)..etc"

If embed no longer works for you, try with /v instead:

        }
});

I have created step by step instructions on how to do this as I also was very confused about how to get this working.

How to make a self extracting archive that runs your setup.exe with 7zip -sfx switch

Here are the steps.

Step 1 - Setup your installation folder

To make this easy create a folder c:\Install. This is where we will copy all the required files.

Step 2 - 7Zip your installers

1. Go to the folder that has your .msi and your setup.exe
2. Select both the .msi and the setup.exe
3. Right-Click and choose 7Zip --> "Add to Archive"
4. Name your archive "Installer.7z" (or a name of your choice)
5. Click Ok
6. You should now have "Installer.7z".
7. Copy this .7z file to your c:\Install directory

Step 3 - Get the 7z-Extra sfx extension module

You need to download 7zSD.sfx

1. Download one of the LZMA packages from here
2. Extract the package and find 7zSD.sfx in the bin folder.
3. Copy the file "7zSD.sfx" to c:\Install

Step 4 - Setup your config.txt

I would recommend using NotePad++ to edit this text file as you will need to encode in UTF-8, the following instructions are using notepad++.

1. Using windows explorer go to c:\Install
2. right-click and choose "New Text File" and name it config.txt
3. right-click and choose "Edit with NotePad++
4. Click the "Encoding Menu" and choose "Encode in UTF-8"

5. Enter something like this:

   ;!@Install@!UTF-8!
   Title="SOFTWARE v1.0.0.0"
   BeginPrompt="Do you want to install SOFTWARE v1.0.0.0?"
   RunProgram="setup.exe"
   ;!@InstallEnd@!
   

Edit this replacing [SOFTWARE v1.0.0.0] with your product name. Notes on the parameters and options for the setup file are here.

CheckPoint

You should now have a folder "c:\Install" with the following 3 files:

1. Installer.7z
2. 7zSD.sfx
3. config.txt

Step 5 - Create the archive

These instructions I found on the web but nowhere did it explain any of the 4 steps above.

1. Open a cmd window, Window + R --> cmd --> press enter

2. In the command window type the following

   cd \
   cd Install
   copy /b 7zSD.sfx + config.txt + Installer.7z MyInstaller.exe
   

3. Look in c:\Install and you will now see you have a MyInstaller.exe

You are finished

Run the installer

Double click on MyInstaller.exe and it will prompt with your message. Click OK and the setup.exe will run.

P.S. Note on Automation

Now that you have this working in your c:\Install directory I would create an "Install.bat" file and put the copy script in it.

copy /b 7zSD.sfx + config.txt + Installer.7z MyInstaller.exe

Now you can just edit and run the Install.bat every time you need to rebuild a new version of you deployment package.

I had this problem. So I put like this: PC-NAME\SQLSERVER Since the SQLSERVER the instance name that was set at installation.

Authentication: Windows Authentication

Bash sets the shell variable OSTYPE. From man bash:

Automatically set to a string that describes the operating system on which bash is executing.

This has a tiny advantage over uname in that it doesn't require launching a new process, so will be quicker to execute.

However, I'm unable to find an authoritative list of expected values. For me on Ubuntu 14.04 it is set to 'linux-gnu'. I've scraped the web for some other values. Hence:

case "$OSTYPE" in
  linux*)   echo "Linux / WSL" ;;
  darwin*)  echo "Mac OS" ;; 
  win*)     echo "Windows" ;;
  msys*)    echo "MSYS / MinGW / Git Bash" ;;
  cygwin*)  echo "Cygwin" ;;
  bsd*)     echo "BSD" ;;
  solaris*) echo "Solaris" ;;
  *)        echo "unknown: $OSTYPE" ;;
esac

The asterisks are important in some instances - for example OSX appends an OS version number after the 'darwin'. The 'win' value is actually 'win32', I'm told - maybe there is a 'win64'?

Perhaps we could work together to populate a table of verified values here:

• Linux Ubuntu (incl. WSL): linux-gnu
• Cygwin 64-bit: cygwin
• Msys/MINGW (Git Bash for Windows): msys

(Please append your value if it differs from existing entries)

tightVNC 2.5.X and even pre 2.5 supports multi monitor. When you connect, you get a huge virtual monitor. However, this is also has disadvantages. UltaVNC (Tho when I tried it, was buggy in this area) allows you to connect to one huge virtual monitor or just to 1 screen at a time. (With a button to cycle through them) TightVNC also plan to support such a feature.. (When , no idea) This feature is important as if you have large multi monitors and connecting over a reasonably slow link.. The screen updates are just to slow.. Cutting down to one monitor to focus on is desirable.

I like tightVNC, but UltraVNC seems to have a few more features right now..

I have found tightVNC more solid. And that is why I have stuck with it.

I would try both. They both work well, but I imagine one would suite slightly more then the other.

Your query should work fine, but you have to use the alias parent to show the values of the parent table like this:

select 
  CONCAT(user.user_fname, ' ', user.user_lname) AS 'User Name',
  CONCAT(parent.user_fname, ' ', parent.user_lname) AS 'Parent Name'
from users as user
inner join users as parent on parent.user_parent_id = user.user_id
where user.user_id = $_GET[id];

In addition to MK Yung's answer: make sure you add the public key for wherever you're deploying to the deploy keys for the repo, if you don't want to receive a 403 Forbidden response.

This is an example:

false && true || true   // returns true
false && (true || true) // returns false
(true || true || true)  // returns true
false || true           // returns true
true || false           // returns true

If you want to table do following steps:-

views.py:

def view_info(request):
    objs=Model_name.objects.all()
    ............
    return render(request,'template_name',{'objs':obj})

.html page

 {% for item in objs %}
    <tr> 
         <td>{{ item.field1 }}</td>
         <td>{{ item.field2 }}</td>
         <td>{{ item.field3 }}</td>
         <td>{{ item.field4 }}</td>
    </tr>
       {% endfor %}

Taking Shiraz's idea and running with it...

In your application, are you explicitly defining a domain User Account and Password to access AD?

When you are executing the application explicitly it may be inherently using your credentials (your currently logged in domain account) to interrogate AD. However, when calling the application from the script, I'm not sure if the application is in the System context.

A VBScript example would be as follows:

  Dim objConnection As ADODB.Connection
    Set objConnection = CreateObject("ADODB.Connection")
    objConnection.Provider = "ADsDSOObject"
    objConnection.Properties("User ID") = "MyDomain\MyAccount"
    objConnection.Properties("Password") = "MyPassword"
    objConnection.Open "Active Directory Provider"

If this works, of course it would be best practice to create and use a service account specifically for this task, and to deny interactive login to that account.

There is, indeed, prevision for such feature, look http://www.w3.org/TR/css3-values/#attr-notation

This fiddle should work like what you need, but will not for now.

Unfortunately, it's still a draft, and isn't fully implemented on major browsers.

It does work for content on pseudo-elements, though.

Here's the simplest solution (Jibwa made it seem complicated in another answer), without having to generate indices yourself - just using the ShuffleSplit object to generate 1 split.

import numpy as np 
from sklearn.model_selection import ShuffleSplit # or StratifiedShuffleSplit
sss = ShuffleSplit(n_splits=1, test_size=0.1)

data_size = 100
X = np.reshape(np.random.rand(data_size*2),(data_size,2))
y = np.random.randint(2, size=data_size)

sss.get_n_splits(X, y)
train_index, test_index = next(sss.split(X, y)) 

X_train, X_test = X[train_index], X[test_index] 
y_train, y_test = y[train_index], y[test_index]

After displaying the first 1000 records, you can page through them by clicking on the icon beside "Fetch rows:" in the header of the result grid.

You can look into UglifyJS: http://jstarrdewar.com/blog/2013/02/28/use-uglify-to-automatically-strip-debug-messages-from-your-javascript/, https://github.com/mishoo/UglifyJS I haven't tried it yet.

Quoting,

 if (typeof DEBUG === 'undefined') DEBUG = true; // will be removed

 function doSomethingCool() {
     DEBUG && console.log("something cool just happened"); // will be removed }

...The log message line will be removed by Uglify's dead-code remover (since it will erase any conditional that will always evaluate to false). So will that first conditional. But when you are testing as uncompressed code, DEBUG will start out undefined, the first conditional will set it to true, and all your console.log() messages will work.

the localhost:8080 means your explicitly targeting port 8080.

To send a variable value through URL in response.sendRedirect(). I have used it for one variable, you can also use it for two variable by proper concatenation.

String value="xyz";

response.sendRedirect("/content/test.jsp?var="+value);

EDIT: I just realised after reading your question again, that i did not answer your question. You want to enter multiple lines in the same plot. However, I'll leave it be, because this served me very well multiple times. I hope you find usefull someday

I found this a while back when learning python

import matplotlib.pyplot as plt
import matplotlib.gridspec as gridspec

fig = plt.figure() 
# create figure window

gs = gridspec.GridSpec(a, b)
# Creates grid 'gs' of a rows and b columns 


ax = plt.subplot(gs[x, y])
# Adds subplot 'ax' in grid 'gs' at position [x,y]


ax.set_ylabel('Foo') #Add y-axis label 'Foo' to graph 'ax' (xlabel for x-axis)


fig.add_subplot(ax) #add 'ax' to figure

you can make different sizes in one figure as well, use slices in that case:

 gs = gridspec.GridSpec(3, 3)
 ax1 = plt.subplot(gs[0,:]) # row 0 (top) spans all(3) columns

consult the docs for more help and examples. This little bit i typed up for myself once, and is very much based/copied from the docs as well. Hope it helps... I remember it being a pain in the #$% to get acquainted with the slice notation for the different sized plots in one figure. After that i think it's very simple :)

Note that, image slicing is not creating a copy of the cropped image but creating a pointer to the roi. If you are loading so many images, cropping the relevant parts of the images with slicing, then appending into a list, this might be a huge memory waste.

Suppose you load N images each is >1MP and you need only 100x100 region from the upper left corner.

Slicing:

X = []
for i in range(N):
    im = imread('image_i')
    X.append(im[0:100,0:100]) # This will keep all N images in the memory. 
                              # Because they are still used.

Alternatively, you can copy the relevant part by .copy(), so garbage collector will remove im.

X = []
for i in range(N):
    im = imread('image_i')
    X.append(im[0:100,0:100].copy()) # This will keep only the crops in the memory. 
                                     # im's will be deleted by gc.

After finding out this, I realized one of the comments by user1270710 mentioned that but it took me quite some time to find out (i.e., debugging etc). So, I think it worths mentioning.

Even though I was putting the certificates in cacerts, I was still getting the error. Turns our I was putting them in jre, not in jdk/jre.

There are two keystores, keep that in mind!!!

The discoverability is dismal, but it's quite clever how Advanced Rest Client handles basic authentication. The shortcut abraham mentioned didn't work for me, but a little poking around revealed how it does it.

The first thing you need to do is add the Authorization header:

Then, a nifty little thing pops up when you focus the value input (note the "construct" box in the lower right):

Clicking it will bring up a box. It even does OAuth, if you want!

Tada! If you leave the value field blank when you click "construct," it will add the Basic part to it (I assume it will also add the necessary OAuth stuff, too, but I didn't try that, as my current needs were for basic authentication), so you don't need to do anything.

Maybe Math.floor(value * 100) / 100? Beware that the values like 3.54 may be not exactly represented with a double.

Embedded environment, sometime, there is no MMU, less memory, less storage space. In C programming level, almost same, cross compiler do their job.

For strings, forget about using WHENCE: use f.seek(0) to position at beginning of file and f.seek(len(f)+1) to position at the end of file. Use open(file, "r+") to read/write anywhere in a file. If you use "a+" you'll only be able to write (append) at the end of the file regardless of where you position the cursor.

Sometimes using   instead of spaces will work. Clearly it has drawbacks, though.

EF doesn't support unique columns except keys. If you are using EF Migrations you can force EF to create unique index on UserName column (in migration code, not by any annotation) but the uniqueness will be enforced only in the database. If you try to save duplicate value you will have to catch exception (constraint violation) fired by the database.

if you are using custom CSS instead of defining modal class as "modal fade" or "modal fade in" change it to only "modal" in HTML page then try again.

I don't know if it's possible to run it just like that.

I usually first copy it with scp and then log in to run it.

scp foo.sh user@host:~
ssh user@host
./foo.sh

There's a lot of comment plugins for vim - a number of which are multi-language - not just python. If you use a plugin manager like Vundle then you can search for them (once you've installed Vundle) using e.g.:

:PluginSearch comment

And you will get a window of results. Alternatively you can just search vim-scripts for comment plugins.

Be aware of that only 32 bit version of PHP is available on the Windows platform.

Then if you for instance shift << or >> more than by 31 bits, results are unexpectable. Usually the original number instead of zeros will be returned, and it can be a really tricky bug.

Of course if you use 64 bit version of PHP (Unix), you should avoid shifting by more than 63 bits. However, for instance, MySQL uses the 64-bit BIGINT, so there should not be any compatibility problems.

UPDATE: From PHP 7 Windows, PHP builds are finally able to use full 64 bit integers: The size of an integer is platform-dependent, although a maximum value of about two billion is the usual value (that's 32 bits signed). 64-bit platforms usually have a maximum value of about 9E18, except on Windows prior to PHP 7, where it was always 32 bit.

try this it work out for me perfectly go to project and right click on your java file at the right corner, go to properties, go to run, go to browse, and then select Main class. now you can run your program again.

You should open up IE on the server for which you are looking for this info, and go to this site: http://www.hanselman.com/smallestdotnet/

That's all it takes.

The site has a script that looks your browser's "UserAgent" and figures out what version (if any) of the .NET Framework you have (or don't have) installed, and displays it automatically (then calculates the total size if you chose to download the .NET Framework).

From the Python PEP 8 -- Style Guide for Python Code:

Descriptive: Naming Styles

The following special forms using leading or trailing underscores are recognized (these can generally be combined with any case convention):

• _single_leading_underscore: weak "internal use" indicator. E.g. from M import * does not import objects whose name starts with an underscore.

• single_trailing_underscore_: used by convention to avoid conflicts with Python keyword, e.g.

  Tkinter.Toplevel(master, class_='ClassName')

• __double_leading_underscore: when naming a class attribute, invokes name mangling (inside class FooBar, __boo becomes _FooBar__boo; see below).

• __double_leading_and_trailing_underscore__: "magic" objects or attributes that live in user-controlled namespaces. E.g. __init__, __import__ or __file__. Never invent such names; only use them as documented.

Note that names with double leading and trailing underscores are essentially reserved for Python itself: "Never invent such names; only use them as documented".

The following regex extract anything between the parenthesis:

PS> $prog = [regex]::match($s,'\(([^\)]+)\)').Groups[1].Value
PS> $prog
SUB RAD MSD 50R III


Explanation (created with RegexBuddy)

Match the character '(' literally «\(»
Match the regular expression below and capture its match into backreference number 1 «([^\)]+)»
   Match any character that is NOT a ) character «[^\)]+»
      Between one and unlimited times, as many times as possible, giving back as needed (greedy) «+»
Match the character ')' literally «\)»

As already mentioned in multiple answers, using virtualenv is a clean solution. However a small pitfall that everyone should be aware of is that if an alias for python is set in bash_aliases like:

python=python3.6

this alias will also be used inside the virtual environment. So in this scenario running python -V inside the virtual env will always output 3.6 regardless of what interpreter is used to create the environment:

virtualenv venv --python=pythonX.X

You can separate multiple classes with the space:

$("p").addClass("myClass yourClass");

http://api.jquery.com/addClass/

https://www.npmjs.com/package/crypto-extra has a method for it :)

var value = crypto.random(/* desired length */)

This solution is useful when your object has Specific Type. Like when obtaining the object to other source.

let user: User = new User();
(user as any).otherProperty = 'hello';
//user did not lose its type here.

I've found the liquibase.database.typeconversion.core.AbstractTypeConverter class. It lists all types that can be used:

protected DataType getDataType(String columnTypeString, Boolean autoIncrement, String dataTypeName, String precision, String additionalInformation) {
    // Translate type to database-specific type, if possible
    DataType returnTypeName = null;
    if (dataTypeName.equalsIgnoreCase("BIGINT")) {
        returnTypeName = getBigIntType();
    } else if (dataTypeName.equalsIgnoreCase("NUMBER") || dataTypeName.equalsIgnoreCase("NUMERIC")) {
        returnTypeName = getNumberType();
    } else if (dataTypeName.equalsIgnoreCase("BLOB")) {
        returnTypeName = getBlobType();
    } else if (dataTypeName.equalsIgnoreCase("BOOLEAN")) {
        returnTypeName = getBooleanType();
    } else if (dataTypeName.equalsIgnoreCase("CHAR")) {
        returnTypeName = getCharType();
    } else if (dataTypeName.equalsIgnoreCase("CLOB")) {
        returnTypeName = getClobType();
    } else if (dataTypeName.equalsIgnoreCase("CURRENCY")) {
        returnTypeName = getCurrencyType();

        returnTypeName = getIntType();
    } else if (dataTypeName.equalsIgnoreCase("INTEGER")) {
        returnTypeName = getIntType();
    } else if (dataTypeName.equalsIgnoreCase("LONGBLOB")) {
        returnTypeName = getLongBlobType();
    } else if (dataTypeName.equalsIgnoreCase("LONGVARBINARY")) {
        returnTypeName = getBlobType();
    } else if (dataTypeName.equalsIgnoreCase("LONGVARCHAR")) {

The name of the inputs must be the same to belong to the same group. Then the others will be automatically deselected when one is clicked.

I have the same problem with you when I implement OpenCV 2.4.11 on VS 2015. I tried to solve this problem by three methods one by one but they didn't work:

1. download MSVCP120.DLL online and add it to windows path and OpenCV bin file path
2. install Visual C++ Redistributable Packages for Visual Studio 2013 both x86 and x86
3. adjust Debug mode. Go to configuration > C/C++ > Code Generation > Runtime Library and select Multi-threaded Debug (/MTd)

Finally I solved this problem by reinstalling VS2015 with selecting all the options that can be installed, it takes a lot space but it really works.

There are more than that. The executed executables are different.

npm run start

will run your projects local executable which is located in your node_modules/.bin.

ng serve

will run another executable which is global.

It means if you clone and install an Angular project which is created with angular-cli version 5 and your global cli version is 7, then you may have problems with ng build.

For those wondering how to get the scroll event for the bootstrap 3 modal:

$(".modal").scroll(function() {

});

Your second DELETE query was nearly correct. Just be sure to put the table name (or an alias) between DELETE and FROM to specify which table you are deleting from. This is simpler than using a nested SELECT statement like in the other answers.

Corrected Query (option 1: using full table name):

DELETE tableA
FROM tableA
INNER JOIN tableB u on (u.qlabel = tableA.entityrole AND u.fieldnum = tableA.fieldnum) 
WHERE (LENGTH(tableA.memotext) NOT IN (8,9,10)
OR tableA.memotext NOT LIKE '%/%/%')
AND (u.FldFormat = 'Date')

Corrected Query (option 2: using an alias):

DELETE q
FROM tableA q
INNER JOIN tableB u on (u.qlabel = q.entityrole AND u.fieldnum = q.fieldnum) 
WHERE (LENGTH(q.memotext) NOT IN (8,9,10) 
OR q.memotext NOT LIKE '%/%/%')
AND (u.FldFormat = 'Date')

You can use either way:

SELECT RIGHT(RTRIM(columnName), 3)

OR

SELECT SUBSTRING(columnName, LEN(columnName)-2, 3)

Here is another, in my opinion even simpler solution using a flex wrapper:

HTML:

<div class="wrapper">
  <p>Text</p>
  <div class="line"></div>
</div>

CSS:

.wrapper {
  display: flex;
  align-items: center;
}

.line {
  border-top: 1px solid grey;
  flex-grow: 1;
  margin: 0 10px;
}

JSFiddle

You can add style for :after a like html code.
For example:

var value = 22;
body.append('<style>.wrapper:after{border-top-width: ' + value + 'px;}</style>');

pgAdmin has GUI for data import since 1.16. You have to create your table first and then you can import data easily - just right-click on the table name and click on Import.

public class ThreadParameter
        {
            public int Port { get; set; }
            public string Path { get; set; }
        }


Thread t = new Thread(new ParameterizedThreadStart(Startup));
t.Start(new ThreadParameter() { Port = port, Path = path});

Create an object with the port and path objects and pass it to the Startup method.

There are a few different ways you can achieve what you are asking for.

1.) Extend the application class and instantiate your controller and model objects there.

public class FavoriteColorsApplication extends Application {

    private static FavoriteColorsApplication application;
    private FavoriteColorsService service;

    public FavoriteColorsApplication getInstance() {
        return application;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        application = this;
        application.initialize();
    }

    private void initialize() {
        service = new FavoriteColorsService();
    }

    public FavoriteColorsService getService() {
        return service;
    }

}

Then you can call the your singleton from your custom Application object at any time:

public class FavoriteColorsActivity extends Activity {

private FavoriteColorsService service = null;
private ArrayAdapter<String> adapter;
private List<String> favoriteColors = new ArrayList<String>();

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

    service = ((FavoriteColorsApplication) getApplication()).getService();
    favoriteColors = service.findAllColors();

    ListView lv = (ListView) findViewById(R.id.favoriteColorsListView);
    adapter = new ArrayAdapter<String>(this, R.layout.favorite_colors_list_item,
            favoriteColors);
    lv.setAdapter(adapter);
}

2.) You can have your controller just create a singleton instance of itself:

public class Controller {
    private static final String TAG = "Controller";
    private static sController sController;
    private Dao mDao;

    private Controller() {
        mDao = new Dao();    
    }

    public static Controller create() {
        if (sController == null) {
            sController = new Controller();
        }
        return sController;
    }
}

Then you can just call the create method from any Activity or Fragment and it will create a new controller if one doesn't already exist, otherwise it will return the preexisting controller.

3.) Finally, there is a slick framework created at Square which provides you dependency injection within Android. It is called Dagger. I won't go into how to use it here, but it is very slick if you need that sort of thing.

I hope I gave enough detail in regards to how you can do what you are hoping for.

Basically you have to read it in memory. Open the file, allocate the array, and read the contents from the file into the array.

The simplest way is something similar to this:

public byte[] read(File file) throws IOException, FileTooBigException {
    if (file.length() > MAX_FILE_SIZE) {
        throw new FileTooBigException(file);
    }
    ByteArrayOutputStream ous = null;
    InputStream ios = null;
    try {
        byte[] buffer = new byte[4096];
        ous = new ByteArrayOutputStream();
        ios = new FileInputStream(file);
        int read = 0;
        while ((read = ios.read(buffer)) != -1) {
            ous.write(buffer, 0, read);
        }
    }finally {
        try {
            if (ous != null)
                ous.close();
        } catch (IOException e) {
        }

        try {
            if (ios != null)
                ios.close();
        } catch (IOException e) {
        }
    }
    return ous.toByteArray();
}

This has some unnecessary copying of the file content (actually the data is copied three times: from file to buffer, from buffer to ByteArrayOutputStream, from ByteArrayOutputStream to the actual resulting array).

You also need to make sure you read in memory only files up to a certain size (this is usually application dependent) :-).

You also need to treat the IOException outside the function.

Another way is this:

public byte[] read(File file) throws IOException, FileTooBigException {
    if (file.length() > MAX_FILE_SIZE) {
        throw new FileTooBigException(file);
    }

    byte[] buffer = new byte[(int) file.length()];
    InputStream ios = null;
    try {
        ios = new FileInputStream(file);
        if (ios.read(buffer) == -1) {
            throw new IOException(
                    "EOF reached while trying to read the whole file");
        }
    } finally {
        try {
            if (ios != null)
                ios.close();
        } catch (IOException e) {
        }
    }
    return buffer;
}

This has no unnecessary copying.

FileTooBigException is a custom application exception. The MAX_FILE_SIZE constant is an application parameters.

For big files you should probably think a stream processing algorithm or use memory mapping (see java.nio).

Private Sub ListView1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListView1.Click
        Dim tt As String
        tt = ListView1.SelectedItems.Item(0).SubItems(1).Text
        TextBox1.Text = tt.ToString
End Sub

Here is the syntax using jQuery $.get

$.get(url, data, successCallback, datatype)

So in your case, that would equate to,

var url = 'ajax.asp';
var data = { ajaxid: 4, UserID: UserID, EmailAddress: EmailAddress };
var datatype = 'jsonp';

function success(response) {
// do something here 
}

$.get('ajax.aspx', data, success, datatype)

Note $.get does not give you the opportunity to set an error handler. But there are several ways to do it either using $.ajaxSetup(), $.ajaxError() or chaining a .fail on your $.get like below

$.get(url, data, success, datatype)
 .fail(function(){
})

The reason for setting the datatype as 'jsonp' is due to browser same origin policy issues, but if you are making the request on the same domain where your javascript is hosted, you should be fine with datatype set to json.

If you don't want to use the jquery $.get then see the docs for $.ajax which allows room for more flexibility

Use LayoutParams (as explained already). However be careful which LayoutParams to choose. According to https://stackoverflow.com/a/11971553/3184778 "you need to use the one that relates to the PARENT of the view you're working on, not the actual view"

If for example the TextView is inside a TableRow, then you need to use TableRow.LayoutParams instead of RelativeLayout or LinearLayout

Use cli utility keytool from java software distribution for import (and trust!) needed certificates

Sample:

1. From cli change dir to jre\bin

2. Check keystore (file found in jre\bin directory)
   keytool -list -keystore ..\lib\security\cacerts
   Enter keystore password: changeit

3. Download and save all certificates chain from needed server.

4. Add certificates (before need to remove "read-only" attribute on file "..\lib\security\cacerts") keytool -alias REPLACE_TO_ANY_UNIQ_NAME -import -keystore ..\lib\security\cacerts -file "r:\root.crt"

accidentally I found such a simple tip. Other solutions require the use of InstallCert.Java and JDK

try this

SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
String string  = dateFormat.format(new Date());
System.out.println(string);

you can create any format see this

You can clone the module directly in to your local project.

Start terminal. cd in to your project and then:

npm install https://github.com/repo/npm_module.git --save

SuperM answer worked for me but with Uri.fromFile() instead of Uri.parse().

With Uri.parse(), it worked only with Whatsapp.

This is my code:

sharingIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(mFile));

Output of Uri.parse():
/storage/emulated/0/Android/data/application_package/Files/17072015_0927.jpg

Output of Uri.fromFile:
file:///storage/emulated/0/Android/data/application_package/Files/17072015_0927.jpg

try this way:

python -m pip install --user boto3

jQuery's attr method returns the value of the attribute:

The .attr() method gets the attribute value for only the first element in the matched set. To get the value for each element individually, use a looping construct such as jQuery's .each() or .map() method.

All you need is:

$('html').attr('lang') == 'fr-FR'

However, you might want to do a case-insensitive match:

$('html').attr('lang').toLowerCase() === 'fr-fr'

jQuery's val method returns the value of a form element.

The .val() method is primarily used to get the values of form elements such as input, select and textarea. In the case of <select multiple="multiple"> elements, the .val() method returns an array containing each selected option; if no option is selected, it returns null.

I had a similar issue where I had another class something like this:

public class Something {
  MyActivity myActivity;

  public Something(MyActivity myActivity) {
    this.myActivity=myActivity;
  }

  public void someMethod() {
   .
   .
   AlertDialog.Builder builder = new AlertDialog.Builder(myActivity);
   .
   AlertDialog alert = builder.create();
   alert.show();
  }
}

Worked fine most of the time, but sometimes it crashed with the same error. Then I realise that in MyActivity I had...

public class MyActivity extends Activity {
  public static Something something;

  public void someMethod() {
    if (something==null) {
      something=new Something(this);
    }
  }
}

Because I was holding the object as static, a second run of the code was still holding the original version of the object, and thus was still referring to the original Activity, which no long existed.

Silly stupid mistake, especially as I really didn't need to be holding the object as static in the first place...

The syntax of TINYINT data type is TINYINT(M),

where M indicates the maximum display width (used only if your MySQL client supports it).

The (m) indicates the column width in SELECT statements; however, it doesn't control the accepted range of numbers for that field.

A TINYINT is an 8-bit integer value, a BIT field can store between 1 bit, BIT(1), and 64 >bits, BIT(64). For a boolean values, BIT(1) is pretty common.

TINYINT()

You're looking for the FromBase64Transform class, used with the CryptoStream class.

If you have a string, you can also call Convert.FromBase64String.

I would add an identifying Id or class to the dropbox and remove using Javascript.

The article here should help.

Have a look at git show-branch

There's a lot you can do with core git functionality. It might be good to specify what you'd like to include in your visual diff. Most answers focus on line-by-line diffs of commits, where your example focuses on names of files affected in a given commit.

One visual that seems not to be addressed is how to see the commits that branches contain (whether in common or uniquely).

For this visual, I'm a big fan of git show-branch; it breaks out a well organized table of commits per branch back to the common ancestor. - to try it on a repo with multiple branches with divergences, just type git show-branch and check the output - for a writeup with examples, see Compare Commits Between Git Branches

Your code sample didn't expand on part of your topic, namely symbols, and so that part of the question went unanswered.

If you have two strings, foo and bar, and both can be either a string or a symbol, you can test equality with

foo.to_s == bar.to_s

It's a little more efficient to skip the string conversions on operands with known type. So if foo is always a string

foo == bar.to_s

But the efficiency gain is almost certainly not worth demanding any extra work on behalf of the caller.

Prior to Ruby 2.2, avoid interning uncontrolled input strings for the purpose of comparison (with strings or symbols), because symbols are not garbage collected, and so you can open yourself to denial of service through resource exhaustion. Limit your use of symbols to values you control, i.e. literals in your code, and trusted configuration properties.

Ruby 2.2 introduced garbage collection of symbols.

Add a style = color:black !important; in your input type.

A metaphorical explanation:

I have a parcel I want delivered to a friend, and I also want to know when my friend receives it.

So I take the parcel to the post office and ask them to deliver it. If I want to know when my friend receives the parcel, I have two options:

(a) I can wait at the post office until it is delivered.

(b) I will get an email when it is delivered.

Option (b) is analogous to a callback.

#include <stdio.h>
main()
{
    char str[100];
    int num;
    while(1) {
        printf("Enter a number: ");
        scanf("%[^0-9]%d",str,&num);
        printf("You entered the number %d\n",num);
    }
    return 0;
}

%[^0-9] in scanf() gobbles up all that is not between 0 and 9. Basically it cleans the input stream of non-digits and puts it in str. Well, the length of non-digit sequence is limited to 100. The following %d selects only integers in the input stream and places it in num.

Beginner

Introductory, no previous programming experience

• C++ Primer * (Stanley Lippman, Josée Lajoie, and Barbara E. Moo) (updated for C++11) Coming at 1k pages, this is a very thorough introduction into C++ that covers just about everything in the language in a very accessible format and in great detail. The fifth edition (released August 16, 2012) covers C++11. [Review]

  ^{* Not to be confused with C++ Primer Plus (Stephen Prata), with a significantly less favorable review.}

• Programming: Principles and Practice Using C++ (Bjarne Stroustrup, 2nd Edition - May 25, 2014) (updated for C++11/C++14) An introduction to programming using C++ by the creator of the language. A good read, that assumes no previous programming experience, but is not only for beginners.

Introductory, with previous programming experience

• A Tour of C++ (Bjarne Stroustrup) (2nd edition for C++17) The “tour” is a quick (about 180 pages and 14 chapters) tutorial overview of all of standard C++ (language and standard library, and using C++11) at a moderately high level for people who already know C++ or at least are experienced programmers. This book is an extended version of the material that constitutes Chapters 2-5 of The C++ Programming Language, 4th edition.

• Accelerated C++ (Andrew Koenig and Barbara Moo, 1st Edition - August 24, 2000) This basically covers the same ground as the C++ Primer, but does so on a fourth of its space. This is largely because it does not attempt to be an introduction to programming, but an introduction to C++ for people who've previously programmed in some other language. It has a steeper learning curve, but, for those who can cope with this, it is a very compact introduction to the language. (Historically, it broke new ground by being the first beginner's book to use a modern approach to teaching the language.) Despite this, the C++ it teaches is purely C++98. [Review]

Best practices

• Effective C++ (Scott Meyers, 3rd Edition - May 22, 2005) This was written with the aim of being the best second book C++ programmers should read, and it succeeded. Earlier editions were aimed at programmers coming from C, the third edition changes this and targets programmers coming from languages like Java. It presents ~50 easy-to-remember rules of thumb along with their rationale in a very accessible (and enjoyable) style. For C++11 and C++14 the examples and a few issues are outdated and Effective Modern C++ should be preferred. [Review]

• Effective Modern C++ (Scott Meyers) This is basically the new version of Effective C++, aimed at C++ programmers making the transition from C++03 to C++11 and C++14.

• Effective STL (Scott Meyers) This aims to do the same to the part of the standard library coming from the STL what Effective C++ did to the language as a whole: It presents rules of thumb along with their rationale. [Review]

Intermediate

• More Effective C++ (Scott Meyers) Even more rules of thumb than Effective C++. Not as important as the ones in the first book, but still good to know.

• Exceptional C++ (Herb Sutter) Presented as a set of puzzles, this has one of the best and thorough discussions of the proper resource management and exception safety in C++ through Resource Acquisition is Initialization (RAII) in addition to in-depth coverage of a variety of other topics including the pimpl idiom, name lookup, good class design, and the C++ memory model. [Review]

• More Exceptional C++ (Herb Sutter) Covers additional exception safety topics not covered in Exceptional C++, in addition to discussion of effective object-oriented programming in C++ and correct use of the STL. [Review]

• Exceptional C++ Style (Herb Sutter) Discusses generic programming, optimization, and resource management; this book also has an excellent exposition of how to write modular code in C++ by using non-member functions and the single responsibility principle. [Review]

• C++ Coding Standards (Herb Sutter and Andrei Alexandrescu) “Coding standards” here doesn't mean “how many spaces should I indent my code?” This book contains 101 best practices, idioms, and common pitfalls that can help you to write correct, understandable, and efficient C++ code. [Review]

• C++ Templates: The Complete Guide (David Vandevoorde and Nicolai M. Josuttis) This is the book about templates as they existed before C++11. It covers everything from the very basics to some of the most advanced template metaprogramming and explains every detail of how templates work (both conceptually and at how they are implemented) and discusses many common pitfalls. Has excellent summaries of the One Definition Rule (ODR) and overload resolution in the appendices. A second edition covering C++11, C++14 and C++17 has been already published. [Review]

• C++ 17 - The Complete Guide (Nicolai M. Josuttis) This book describes all the new features introduced in the C++17 Standard covering everything from the simple ones like 'Inline Variables', 'constexpr if' all the way up to 'Polymorphic Memory Resources' and 'New and Delete with overaligned Data'. [Review]

• C++ in Action (Bartosz Milewski). This book explains C++ and its features by building an application from ground up. [Review]

• Functional Programming in C++ (Ivan Cukic). This book introduces functional programming techniques to modern C++ (C++11 and later). A very nice read for those who want to apply functional programming paradigms to C++.

• Professional C++ (Marc Gregoire, 5th Edition - Feb 2021) Provides a comprehensive and detailed tour of the C++ language implementation replete with professional tips and concise but informative in-text examples, emphasizing C++20 features. Uses C++20 features, such as modules and std::format throughout all examples.

Advanced

• Modern C++ Design (Andrei Alexandrescu) A groundbreaking book on advanced generic programming techniques. Introduces policy-based design, type lists, and fundamental generic programming idioms then explains how many useful design patterns (including small object allocators, functors, factories, visitors, and multi-methods) can be implemented efficiently, modularly, and cleanly using generic programming. [Review]

• C++ Template Metaprogramming (David Abrahams and Aleksey Gurtovoy)

• C++ Concurrency In Action (Anthony Williams) A book covering C++11 concurrency support including the thread library, the atomics library, the C++ memory model, locks and mutexes, as well as issues of designing and debugging multithreaded applications. A second edition covering C++14 and C++17 has been already published. [Review]

• Advanced C++ Metaprogramming (Davide Di Gennaro) A pre-C++11 manual of TMP techniques, focused more on practice than theory. There are a ton of snippets in this book, some of which are made obsolete by type traits, but the techniques, are nonetheless useful to know. If you can put up with the quirky formatting/editing, it is easier to read than Alexandrescu, and arguably, more rewarding. For more experienced developers, there is a good chance that you may pick up something about a dark corner of C++ (a quirk) that usually only comes about through extensive experience.

Reference Style - All Levels

• The C++ Programming Language (Bjarne Stroustrup) (updated for C++11) The classic introduction to C++ by its creator. Written to parallel the classic K&R, this indeed reads very much like it and covers just about everything from the core language to the standard library, to programming paradigms to the language's philosophy. [Review] Note: All releases of the C++ standard are tracked in the question "Where do I find the current C or C++ standard documents?".

• C++ Standard Library Tutorial and Reference (Nicolai Josuttis) (updated for C++11) The introduction and reference for the C++ Standard Library. The second edition (released on April 9, 2012) covers C++11. [Review]

• The C++ IO Streams and Locales (Angelika Langer and Klaus Kreft) There's very little to say about this book except that, if you want to know anything about streams and locales, then this is the one place to find definitive answers. [Review]

The C++17 standard is released in electronic form for 198 Swiss Francs.

• The C++17 standard is available, but seemingly not in an economical form – directly from the ISO it costs 198 Swiss Francs (about $200 US).

The project was announced at CppCon'15 by Bjarne Stroustrup and others and welcomes contributions from the community. Most guidelines are supplemented with a rationale and examples as well as discussions of possible tool support.

The project documents all versions of the C++ standard and the site allows filtering the display for a specific version. The project was presented by Nate Kohl at CppCon'14.

Classics / Older

Note: Some information contained within these books may not be up-to-date or no longer considered best practice.

• The Design and Evolution of C++ (Bjarne Stroustrup) If you want to know why the language is the way it is, this book is where you find answers. This covers everything before the standardization of C++.

• Ruminations on C++ - (Andrew Koenig and Barbara Moo) [Review]

• Advanced C++ Programming Styles and Idioms (James Coplien) A predecessor of the pattern movement, it describes many C++-specific “idioms”. It's certainly a very good book and might still be worth a read if you can spare the time, but quite old and not up-to-date with current C++.

• Large Scale C++ Software Design (John Lakos) Lakos explains techniques to manage very big C++ software projects. Certainly, a good read, if it only was up to date. It was written long before C++ 98 and misses on many features (e.g. namespaces) important for large-scale projects. If you need to work in a big C++ software project, you might want to read it, although you need to take more than a grain of salt with it. The first volume of a new edition is released in 2019.

• Inside the C++ Object Model (Stanley Lippman) If you want to know how virtual member functions are commonly implemented and how base objects are commonly laid out in memory in a multi-inheritance scenario, and how all this affects performance, this is where you will find thorough discussions of such topics.

• The Annotated C++ Reference Manual (Bjarne Stroustrup, Margaret A. Ellis) This book is quite outdated in the fact that it explores the 1989 C++ 2.0 version - Templates, exceptions, namespaces and new casts were not yet introduced. Saying that however, this book goes through the entire C++ standard of the time explaining the rationale, the possible implementations, and features of the language. This is not a book to learn programming principles and patterns on C++, but to understand every aspect of the C++ language.

• Thinking in C++ (Bruce Eckel, 2nd Edition, 2000). Two volumes; is a tutorial style free set of intro level books. Downloads: vol 1, vol 2. Unfortunately they're marred by a number of trivial errors (e.g. maintaining that temporaries are automatically const), with no official errata list. A partial 3^rd party errata list is available at http://www.computersciencelab.com/Eckel.htm, but it is apparently not maintained.

• Scientific and Engineering C++: An Introduction to Advanced Techniques and Examples (John Barton and Lee Nackman) It is a comprehensive and very detailed book that tried to explain and make use of all the features available in C++, in the context of numerical methods. It introduced at the time several new techniques, such as the Curiously Recurring Template Pattern (CRTP, also called Barton-Nackman trick). It pioneered several techniques such as dimensional analysis and automatic differentiation. It came with a lot of compilable and useful code, ranging from an expression parser to a Lapack wrapper. The code is still available online. Unfortunately, the books have become somewhat outdated in the style and C++ features, however, it was an incredible tour-de-force at the time (1994, pre-STL). The chapters on dynamics inheritance are a bit complicated to understand and not very useful. An updated version of this classic book that includes move semantics and the lessons learned from the STL would be very nice.

I see 2 options.

1. Using numpy:

   property_a = numpy.array([545., 656., 5.4, 33.])
   property_b = numpy.array([ 1.2,  1.3, 2.3, 0.3])
   good_objects = [True, False, False, True]
   good_indices = [0, 3]
   property_asel = property_a[good_objects]
   property_bsel = property_b[good_indices]
   

2. Using a list comprehension and zip it:

   property_a = [545., 656., 5.4, 33.]
   property_b = [ 1.2,  1.3, 2.3, 0.3]
   good_objects = [True, False, False, True]
   good_indices = [0, 3]
   property_asel = [x for x, y in zip(property_a, good_objects) if y]
   property_bsel = [property_b[i] for i in good_indices]
   

You just need to put attribute "selected" on a particular option instead direct to select element.

Here is snippet for same and multiple working example with different values.

   Select Option 3 :- _x000D_
   <select name="hall" id="hall">_x000D_
    <option>1</option>_x000D_
    <option>2</option>_x000D_
    <option selected="selected">3</option>_x000D_
    <option>4</option>_x000D_
    <option>5</option>_x000D_
   </select>_x000D_
   _x000D_
   <br/>_x000D_
   <br/>_x000D_
   <br/>_x000D_
   Select Option 5 :- _x000D_
   <select name="hall" id="hall">_x000D_
    <option>1</option>_x000D_
    <option>2</option>_x000D_
    <option>3</option>_x000D_
    <option>4</option>_x000D_
    <option selected="selected">5</option>_x000D_
   </select>_x000D_
   _x000D_
    <br/>_x000D_
   <br/>_x000D_
   <br/>_x000D_
   Select Option 2 :- _x000D_
   <select name="hall" id="hall">_x000D_
    <option>1</option>_x000D_
    <option selected="selected">2</option>_x000D_
    <option>3</option>_x000D_
    <option>4</option>_x000D_
    <option>5</option>_x000D_
   </select>

To exclude content and subdirectories:

**/bin/*

To just exclude all subdirectories but take the content, add "/":

**/bin/*/

Firstly — I don't think column1 is not NULL or column1 <> '' makes very much sense. Maybe you meant to write column1 is not NULL and column1 <> '' (AND instead of OR)?

Secondly — because of Hive's "schema on read" approach to table definitions, invalid values will be converted to NULL when you read from them. So, for example, if table1.column1 is of type STRING and table2.column1 is of type INT, then I don't think that table1.column1 IS NOT NULL is enough to guarantee that table2.column1 IS NOT NULL. (I'm not sure about this, though.)

@Cris sorry .This is quote MSDN Microsoft

Methodology

In this experiment, two classes will be compared. The StreamReader and the FileStream class will be directed to read two files of 10K and 200K in their entirety from the application directory.

StreamReader (VB.NET)

sr = New StreamReader(strFileName)
Do
  line = sr.ReadLine()
Loop Until line Is Nothing
sr.Close()

FileStream (VB.NET)

Dim fs As FileStream
Dim temp As UTF8Encoding = New UTF8Encoding(True)
Dim b(1024) As Byte
fs = File.OpenRead(strFileName)
Do While fs.Read(b, 0, b.Length) > 0
    temp.GetString(b, 0, b.Length)
Loop
fs.Close()

Result

FileStream is obviously faster in this test. It takes an additional 50% more time for StreamReader to read the small file. For the large file, it took an additional 27% of the time.

StreamReader is specifically looking for line breaks while FileStream does not. This will account for some of the extra time.

Recommendations

Depending on what the application needs to do with a section of data, there may be additional parsing that will require additional processing time. Consider a scenario where a file has columns of data and the rows are CR/LF delimited. The StreamReader would work down the line of text looking for the CR/LF, and then the application would do additional parsing looking for a specific location of data. (Did you think String. SubString comes without a price?)

On the other hand, the FileStream reads the data in chunks and a proactive developer could write a little more logic to use the stream to his benefit. If the needed data is in specific positions in the file, this is certainly the way to go as it keeps the memory usage down.

FileStream is the better mechanism for speed but will take more logic.

Turns out I had a .csv file at the end of the folder from which I was reading all the images. Once I deleted that it worked alright

Make sure that it's all images and that you don't have any other type of file

Swift 2.2 / I used Dx_'s answer. However, I wanted this functionality on all keyboards. So in my base class I put the code:

func addDoneButtonForTextFields(views: [UIView]) {
    for view in views {
        if let textField = view as? UITextField {
            let doneToolbar = UIToolbar(frame: CGRectMake(0, 0, self.view.bounds.size.width, 50))

            let flexSpace = UIBarButtonItem(barButtonSystemItem: .FlexibleSpace, target: nil, action: nil)
            let done = UIBarButtonItem(title: "Done", style: .Done, target: self, action: #selector(dismissKeyboard))

            var items = [UIBarButtonItem]()
            items.append(flexSpace)
            items.append(done)

            doneToolbar.items = items
            doneToolbar.sizeToFit()

            textField.inputAccessoryView = doneToolbar
        } else {
            addDoneButtonForTextFields(view.subviews)
        }
    }
}

func dismissKeyboard() {
    dismissKeyboardForTextFields(self.view.subviews)
}

func dismissKeyboardForTextFields(views: [UIView]) {
    for view in views {
        if let textField = view as? UITextField {
            textField.resignFirstResponder()
        } else {
            dismissKeyboardForTextFields(view.subviews)
        }
    }
}

Then just call addDoneButtonForTextFields on self.view.subviews in viewDidLoad (or willDisplayCell if using a table view) to add the Done button to all keyboards.

Common Resource Grep (crgrep) will search for string matches in tables/columns by name or content and supports a number of DBs, including SQLServer, Oracle and others. Full wild-carding and other useful options.

It's opensource (I'm the author).

Depending on the purpose of setting the display property, you might want to take a look at

$("#yourElementID").show()

and

$("#yourElementID").hide()

There are lots of different ways to do this. One way is to use the RewriteRule techniques mentioned earlier to mask query string values.

One of the ways I really like is if you use the front controller pattern, you can also use urls like http://yoursite.com/index.php/path/to/your/page/here and parse the value of $_SERVER['REQUEST_URI'].

You can easily extract the /path/to/your/page/here bit with the following bit of code:

$route = substr($_SERVER['REQUEST_URI'], strlen($_SERVER['SCRIPT_NAME']));

From there, you can parse it however you please, but for pete's sake make sure you sanitise it ;)

You can try this:-

   <a href="some.htm" target="_blank">Link Text</a>

and you can try this one also:-

  <a href="some.htm" onclick="if(!event.ctrlKey&&!window.opera){alert('Hold the Ctrl Key');return false;}else{return true;}" target="_blank">Link Text</a>

I use three flags to resolve the problem:

intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|
                Intent.FLAG_ACTIVITY_CLEAR_TASK | 
                Intent.FLAG_ACTIVITY_NEW_TASK);

I prefer using RaphaelJS because it has great cross-browser abilities. However, some SVG & VML effects can't be achieved with RaphaelJS (complex gradients...).

Google has also developped a library of its own to enable SVG support in IE: http://svgweb.googlecode.com/files/svgweb-2009-08-20-B.zip

While probably not as clean looking as the IConvertible approach, you could always use the straightforward checking typeof(T) to return a T:

public static T ReturnType<T>(string stringValue)
{
    if (typeof(T) == typeof(int))
        return (T)(object)1;
    else if (typeof(T) == typeof(FooBar))
        return (T)(object)new FooBar(stringValue);
    else
        return default(T);
}

public class FooBar
{
    public FooBar(string something)
    {}
}

This was bugging me too, since this was a standard feature in Sublime Text 2, but somehow automatic indentation no longer worked in Sublime Text 3 for HTML files.

My solution was to find the Miscellaneous.tmPreferences file from Sublime Text 2 (found under %AppData%/Roaming/Sublime Text 2/Packages/HTML) and copy those settings to the same file for ST3.

Now package handling has been made more difficult for ST3, but luckily you can just add the files to your %AppData%/Roaming/Sublime Text 3/Packages folder and they overwrite default settings in the install directory. Just save this file as "%AppData%/Roaming/Sublime Text 3/Packages/HTML/Miscellaneous.tmPreferences" and auto indent works again like it did in ST2.

Your syntax isn't quite right: you need to list the fields in order before the INTO, and the corresponding target variables after:

SELECT Id, dateCreated
INTO iId, dCreate
FROM products
WHERE pName = iName

There's a bit of confusion in your question:

• a Date datatype doesn't save the time zone component. This piece of information is truncated and lost forever when you insert a TIMESTAMP WITH TIME ZONE into a Date.
• When you want to display a date, either on screen or to send it to another system via a character API (XML, file...), you use the TO_CHAR function. In Oracle, a Date has no format: it is a point in time.
• Reciprocally, you would use TO_TIMESTAMP_TZ to convert a VARCHAR2 to a TIMESTAMP, but this won't convert a Date to a TIMESTAMP.
• You use FROM_TZ to add the time zone information to a TIMESTAMP (or a Date).
• In Oracle, CST is a time zone but CDT is not. CDT is a daylight saving information.
• To complicate things further, CST/CDT (-05:00) and CST/CST (-06:00) will have different values obviously, but the time zone CST will inherit the daylight saving information depending upon the date by default.

So your conversion may not be as simple as it looks.

Assuming that you want to convert a Date d that you know is valid at time zone CST/CST to the equivalent at time zone CST/CDT, you would use:

SQL> SELECT from_tz(d, '-06:00') initial_ts,
  2         from_tz(d, '-06:00') at time zone ('-05:00') converted_ts
  3    FROM (SELECT cast(to_date('2012-10-09 01:10:21',
  4                              'yyyy-mm-dd hh24:mi:ss') as timestamp) d
  5            FROM dual);

INITIAL_TS                      CONVERTED_TS
------------------------------- -------------------------------
09/10/12 01:10:21,000000 -06:00 09/10/12 02:10:21,000000 -05:00

My default timestamp format has been used here. I can specify a format explicitely:

SQL> SELECT to_char(from_tz(d, '-06:00'),'yyyy-mm-dd hh24:mi:ss TZR') initial_ts,
  2         to_char(from_tz(d, '-06:00') at time zone ('-05:00'),
  3                 'yyyy-mm-dd hh24:mi:ss TZR') converted_ts
  4    FROM (SELECT cast(to_date('2012-10-09 01:10:21',
  5                              'yyyy-mm-dd hh24:mi:ss') as timestamp) d
  6            FROM dual);

INITIAL_TS                      CONVERTED_TS
------------------------------- -------------------------------
2012-10-09 01:10:21 -06:00      2012-10-09 02:10:21 -05:00

Something a little shorter in syntax but taking what the others have already stated.

int num1, num2 = num1 = 1;

The overall dimensions of a range are in its Width and Height properties.

Dim r As Range
Set r = ActiveSheet.Range("A4:H12")

Debug.Print r.Width
Debug.Print r.Height

You can use the os module.

>>> import os
>>> os.getcwd()
'/home/user'
>>> os.chdir("/tmp/")
>>> os.getcwd()
'/tmp'

But if it's about finding other modules: You can set an environment variable called PYTHONPATH, under Linux would be like

export PYTHONPATH=/path/to/my/library:$PYTHONPATH

Then, the interpreter searches also at this place for imported modules. I guess the name would be the same under Windows, but don't know how to change.

edit

Under Windows:

set PYTHONPATH=%PYTHONPATH%;C:\My_python_lib

(taken from http://docs.python.org/using/windows.html)

... and even better: use virtualenv and virtualenv_wrapper, this will allow you to create a development environment where you can add module paths as you like (add2virtualenv) without polluting your installation or "normal" working environment.

http://virtualenvwrapper.readthedocs.org/en/latest/command_ref.html

If your $VARIABLE is a string containing spaces or other special characters, and single square brackets are used (which is a shortcut for the test command), then the string may be split out into multiple words. Each of these is treated as a separate argument.

So that one variable is split out into many arguments:

VARIABLE=$(/some/command);  
# returns "hello world"

if [ $VARIABLE == 0 ]; then
  # fails as if you wrote:
  # if [ hello world == 0 ]
fi 

The same will be true for any function call that puts down a string containing spaces or other special characters.

Easy fix

Wrap the variable output in double quotes, forcing it to stay as one string (therefore one argument). For example,

VARIABLE=$(/some/command);
if [ "$VARIABLE" == 0 ]; then
  # some action
fi 

Simple as that. But skip to "Also beware..." below if you also can't guarantee your variable won't be an empty string, or a string that contains nothing but whitespace.

Or, an alternate fix is to use double square brackets (which is a shortcut for the new test command).

This exists only in bash (and apparently korn and zsh) however, and so may not be compatible with default shells called by /bin/sh etc.

This means on some systems, it might work from the console but not when called elsewhere, like from cron, depending on how everything is configured.

It would look like this:

VARIABLE=$(/some/command);
if [[ $VARIABLE == 0 ]]; then
  # some action
fi 

If your command contains double square brackets like this and you get errors in logs but it works from the console, try swapping out the [[ for an alternative suggested here, or, ensure that whatever runs your script uses a shell that supports [[ aka new test.

Also beware of the [: unary operator expected error

If you're seeing the "too many arguments" error, chances are you're getting a string from a function with unpredictable output. If it's also possible to get an empty string (or all whitespace string), this would be treated as zero arguments even with the above "quick fix", and would fail with [: unary operator expected

It's the same 'gotcha' if you're used to other languages - you don't expect the contents of a variable to be effectively printed into the code like this before it is evaluated.

Here's an example that prevents both the [: too many arguments and the [: unary operator expected errors: replacing the output with a default value if it is empty (in this example, 0), with double quotes wrapped around the whole thing:

VARIABLE=$(/some/command);
if [ "${VARIABLE:-0}" == 0 ]; then
  # some action
fi 

(here, the action will happen if $VARIABLE is 0, or empty. Naturally, you should change the 0 (the default value) to a different default value if different behaviour is wanted)

Final note: Since [ is a shortcut for test, all the above is also true for the error test: too many arguments (and also test: unary operator expected)

You can install it using binstar:

conda install -c menpo opencv

Integer is only there for the sql standard ie deprecated by Oracle.

You should use Number instead.

Integers get stored as Number anyway by Oracle behind the scenes.

Most commonly when ints are stored for IDs and such they are defined with no params - so in theory you could look at the scale and precision columns of the metadata views to see of no decimal values can be stored - however 99% of the time this will not help.

As was commented above you could look for number(38,0) columns or similar (ie columns with no decimal points allowed) but this will only tell you which columns cannot take decimals, and not what columns were defined so that INTS can be stored.

Suggestion: do a data profile on the number columns. Something like this:

 select max( case when trunc(column_name,0)=column_name then 0 else 1 end ) as has_dec_vals
 from table_name

Depending on what you're trying to do, you can either block with GetIdList().Result ( generally a bad idea, but it's hard to tell the context) or use a test framework that supports async test methods and have the test method do var results = await GetIdList();

It is true that this calculation does not make sense in a strict mathematical perspective, however if we are checking financial data it is still a useful metric. The formula could be the following:

if(lastyear>0,(thisyear/lastyear-1),((thisyear+abs(lastyear)/abs(lastyear))

let's verify the formula empirically with simple numbers:

thisyear=50 lastyear=25 growth=100% makes sense

thisyear=25 lastyear=50 growth=-50% makes sense

thisyear=-25 lastyear=25 growth=-200% makes sense

thisyear=50 lastyear=-25 growth=300% makes sense

thisyear=-50 lastyear=-25 growth=-100% makes sense

thisyear=-25 lastyear=-50 growth=50% makes sense

again, it might not be mathematically correct, but if you need meaningful numbers (maybe to plug them in graphs or other formulas) it's a good alternative to N/A, especially when using N/A could screw all subsequent calculations.

Just store the index generated in a variable, and then access the array using this varaible:

int idx = new Random().nextInt(fruits.length);
String random = (fruits[idx]);

P.S. I usually don't like generating new Random object per randoization - I prefer using a single Random in the program - and re-use it. It allows me to easily reproduce a problematic sequence if I later find any bug in the program.

According to this approach, I will have some variable Random r somewhere, and I will just use:

int idx = r.nextInt(fruits.length)

However, your approach is OK as well, but you might have hard time reproducing a specific sequence if you need to later on.

Use both @Deprecated annotation and the @deprecated JavaDoc tag.

The @deprecated JavaDoc tag is used for documentation purposes.

The @Deprecated annotation instructs the compiler that the method is deprecated. Here is what it says in Sun/Oracles document on the subject:

Using the @Deprecated annotation to deprecate a class, method, or field ensures that all compilers will issue warnings when code uses that program element. In contrast, there is no guarantee that all compilers will always issue warnings based on the @deprecated Javadoc tag, though the Sun compilers currently do so. Other compilers may not issue such warnings. Thus, using the @Deprecated annotation to generate warnings is more portable that relying on the @deprecated Javadoc tag.

You can find the full document at How and When to Deprecate APIs

This was how added my headers in my flask application and it worked perfectly

@app.after_request
def add_header(response):
    response.headers['X-Content-Type-Options'] = 'nosniff'
    return response

Just as a addition. You can find the Catalina Paths in

->RUN->RUN CONFIGURATIONS->APACHE TOMCAT->ARGUMENTS

In the VM Arguments the Paths are listed and changeable

You may try this:

Cookie::queue($name, $value, $minutes);

This will queue the cookie to use it later and later it will be added with the response when response is ready to be sent. You may check the documentation on Laravel website.

Update (Retrieving A Cookie Value):

$value = Cookie::get('name');

Note: If you set a cookie in the current request then you'll be able to retrieve it on the next subsequent request.

If it's a sorted array you could use a Binary search algorithm (O(log n)). For example, extending the Array-class with this functionality:

class Array
  def b_search(e, l = 0, u = length - 1)
    return if lower_index > upper_index

    midpoint_index = (lower_index + upper_index) / 2
    return midpoint_index if self[midpoint_index] == value

    if value < self[midpoint_index]
      b_search(value, lower_index, upper_index - 1)
    else
      b_search(value, lower_index + 1, upper_index)
    end
  end
end

Using loop in hbs little bit complex

<tbody>
     {{#each item}}
         <tr>
            <td><!--HOW TO GET ARRAY INDEX HERE?--></td>
            <td>{{@index}}</td>
            <td>{{this}}</td>
         </tr>
     {{/each}}
</tbody>

For the point that 'returns the value as soon as you find the first row/record that meets the requirements and NOT iterating other rows', the following code would work:

def pd_iter_func(df):
    for row in df.itertuples():
        # Define your criteria here
        if row.A > 4 and row.B > 3:
            return row

It is more efficient than Boolean Indexing when it comes to a large dataframe.

To make the function above more applicable, one can implements lambda functions:

def pd_iter_func(df: DataFrame, criteria: Callable[[NamedTuple], bool]) -> Optional[NamedTuple]:
    for row in df.itertuples():
        if criteria(row):
            return row

pd_iter_func(df, lambda row: row.A > 4 and row.B > 3)

As mentioned in the answer to the 'mirror' question, pandas.Series.idxmax would also be a nice choice.

def pd_idxmax_func(df, mask):
    return df.loc[mask.idxmax()]

pd_idxmax_func(df, (df.A > 4) & (df.B > 3))

maybe your mysql-server didn't started

you can try

/usr/local/bin/mysql.server start

You can do this

textView.text = "Name: \(string1) \n" + "Phone Number: \(string2)"

The output will be

Name: output of string1 Phone Number: output of string2

Use MySQL(5.6.13) session variable and assignment operator like the following

SELECT @logmsg := CONCAT_ws(',',@logmsg,items) FROM temp_SplitFields a;

then you can get

slice() works like substring() with a few different behaviors.

Syntax: string.slice(start, stop);
Syntax: string.substring(start, stop);

What they have in common:

1. If start equals stop: returns an empty string
2. If stop is omitted: extracts characters to the end of the string
3. If either argument is greater than the string's length, the string's length will be used instead.

Distinctions of substring():

1. If start > stop, then substring will swap those 2 arguments.
2. If either argument is negative or is NaN, it is treated as if it were 0.

Distinctions of slice():

1. If start > stop, slice() will return the empty string. ("")
2. If start is negative: sets char from the end of string, exactly like substr() in Firefox. This behavior is observed in both Firefox and IE.
3. If stop is negative: sets stop to: string.length – Math.abs(stop) (original value), except bounded at 0 (thus, Math.max(0, string.length + stop)) as covered in the ECMA specification.

For react-router v4 you can also bind a listener to change in history event, in the following manner:

let firstMount = true;
const App = (props) => {
    if (typeof window != 'undefined') { //incase you have server-side rendering too             
        firstMount && props.history.listen((location, action) => {
            setImmediate(() => window.scrollTo(0, 0)); // ive explained why i used setImmediate below
        });
        firstMount = false;
    }

    return (

                <Route path='/' exact={true} component={IndexPage} />
                <Route path='/other' component={OtherPage} />
                // ...
             </Switch>

The scroll level will be set to 0 without setImmediate() too if the route is changed by clicking on a link but if user presses back button on browser then it will not work as browser reset the scroll level manually to the previous level when the back button is pressed, so by using setImmediate() we cause our function to be executed after browser is finished resetting the scroll level thus giving us the desired effect.

read with IFS are perfect for this:

$ IFS=- read var1 var2 <<< ABCDE-123456
$ echo "$var1"
ABCDE
$ echo "$var2"
123456

Edit:

Here is how you can read each individual character into array elements:

$ read -a foo <<<"$(echo "ABCDE-123456" | sed 's/./& /g')"

Dump the array:

$ declare -p foo
declare -a foo='([0]="A" [1]="B" [2]="C" [3]="D" [4]="E" [5]="-" [6]="1" [7]="2" [8]="3" [9]="4" [10]="5" [11]="6")'

If there are spaces in the string:

$ IFS=$'\v' read -a foo <<<"$(echo "ABCDE 123456" | sed 's/./&\v/g')"
$ declare -p foo
declare -a foo='([0]="A" [1]="B" [2]="C" [3]="D" [4]="E" [5]=" " [6]="1" [7]="2" [8]="3" [9]="4" [10]="5" [11]="6")'

If you only use this structure for once, i.e. create a global/static variable, you can remove typedef, and initialized this variable instantly:

struct {
    int id;
    char *name;
} employee = {
    .id = 0,
    .name = "none"
};

Then, you can use employee in your code after that.

Something like the standard Collection.toArray(T[]) should do what you need (note that ArrayList implements Collection):

TypeA[] array = a.toArray(new TypeA[a.size()]);

On a side note, you should consider defining a to be of type List<TypeA> rather than ArrayList<TypeA>, this avoid some implementation specific definition that may not really be applicable for your application.

Also, please see this question about the use of a.size() instead of 0 as the size of the array passed to a.toArray(TypeA[])

If you create a web based application, the better solution is to check the directory exists or not then create the file if not exist. If exists, recreate again.

    private File createFile(String path, String fileName) throws IOException {
       ClassLoader classLoader = getClass().getClassLoader();
       File file = new File(classLoader.getResource(".").getFile() + path + fileName);

       // Lets create the directory
       try {
          file.getParentFile().mkdir();
       } catch (Exception err){
           System.out.println("ERROR (Directory Create)" + err.getMessage());
       }

       // Lets create the file if we have credential
       try {
           file.createNewFile();
       } catch (Exception err){
           System.out.println("ERROR (File Create)" + err.getMessage());
       }
       return  file;
   }

You can use code:

if let vc = self.storyboard?.instantiateViewController(withIdentifier: "secondViewController") as? secondViewController {
   let appDelegate = UIApplication.shared.delegate as! AppDelegate
   appDelegate.window?.rootViewController = vc
}

IDisposable is often used to exploit the using statement and take advantage of an easy way to do deterministic cleanup of managed objects.

public class LoggingContext : IDisposable {
    public Finicky(string name) {
        Log.Write("Entering Log Context {0}", name);
        Log.Indent();
    }
    public void Dispose() {
        Log.Outdent();
    }

    public static void Main() {
        Log.Write("Some initial stuff.");
        try {
            using(new LoggingContext()) {
                Log.Write("Some stuff inside the context.");
                throw new Exception();
            }
        } catch {
            Log.Write("Man, that was a heavy exception caught from inside a child logging context!");
        } finally {
            Log.Write("Some final stuff.");
        }
    }
}

you can do it better with two datagridview, you add the same datasource , hide the headers of the second, set the height of the second = to the height of the rows of the first, turn off all resizable atributes of the second, synchronize the scrollbars of both, only horizontal, put the second on the botton of the first etc.

take a look:

   dgv3.ColumnHeadersVisible = false;
   dgv3.Height = dgv1.Rows[0].Height;
   dgv3.Location = new Point(Xdgvx, this.dgv1.Height - dgv3.Height - SystemInformation.HorizontalScrollBarHeight);
   dgv3.Width = dgv1.Width;

   private void dgv1_Scroll(object sender, ScrollEventArgs e)
        {
            if (e.ScrollOrientation == ScrollOrientation.HorizontalScroll)
            {
                dgv3.HorizontalScrollingOffset = e.NewValue;
            }
        }

Public Function TestError() As String()
     Return {"foo", "bar"}
End Function

Works fine for me and should work for you, but you may need allow using implicit declarations in your project. I believe this is turning off Options strict in the Compile section of the program settings.

Since you are using VS 2008 (VB.NET 9.0) you have to declare create the new instance

New String() {"foo", "Bar"}

Googled "Permission denied (publickey). fatal: The remote end hung up unexpectedly", first result an exact SO dupe:

I have another possible answer for those wondering why event log entries are not showing up in the History tab of Task Scheduler for certain tasks, even though All Task History is enabled, the events for those tasks are viewable in the Event Log, and all other tasks show history just fine. In my case, I had created 13 new tasks. For 5 of them, events showed fine under History, but for the other 8, the History tab was completely blank. I even verified these tasks were enabled for history individually (and logging events) using Mick Wood's post about using the Event Viewer.

Then it hit me. I suddenly realized what all 8 had in common that the other 5 did not. They all had an ampersand (&) character in the event name. I created them by exporting the first task I created, "Sync E to N", renaming the exported file name, editing the XML contents, and then importing the new task. Windows Explorer happily let me rename the task, for example, to "Sync C to N & T", and Task Scheduler happily let me import it. However, with that pesky "&" in the name, it could not retrieve its history from the event log. When I deleted the original event, renamed the xml file to "Sync C to N and T", and imported it, voila, there were all of the log entries in the History tab in Task Scheduler.

1. Click on Window > Show view > Server or right click on the server in "Servers" view, select "Properties".
2. In the "General" panel, click on the "Switch Location" button.
3. The "Location: [workspace metadata]" should replace by something else.
4. Open the Overview screen for the server by double clicking it.
5. In the Server locations tab , select "Use Tomcat location".
6. Save the configurations and restart the Server.

You may want to follow the steps above before starting the server. Because server location section goes grayed-unreachable.

If you're using webservices, you'll also need the 'allow-http-request-headers-from' element. Here's our default, development, 'allow everything' policy.

<?xml version="1.0" ?>
<cross-domain-policy>
  <site-control permitted-cross-domain-policies="master-only"/>
  <allow-access-from domain="*"/>
  <allow-http-request-headers-from domain="*" headers="*"/>
</cross-domain-policy>

This is what I use to deep watch an object. My requirement was watching the child fields of the object.

new Vue({
    el: "#myElement",
    data:{
        entity: {
            properties: []
        }
    },
    watch:{
        'entity.properties': {
            handler: function (after, before) {
                // Changes detected.    
            },
            deep: true
        }
    }
});

In my case the app the IPHONEOS_DEPLOYMENT_TARGET was set to 9.3 whereas in my newly created framework it was set to 10.2

The implicit dependencies resolver ignored my new framework because the requirements of the target platform are higher than the app requirements.

After adjusting the framework iOS Deployment Target to match my application deployment target the framework compiled and linked successfully.

NumPy has a numpy.mean which is an arithmetic mean. Usage is as simple as this:

>>> import numpy
>>> a = [1, 2, 4]
>>> numpy.mean(a)
2.3333333333333335

In my own case, i was using serialize() on the form, Hence the files were not being sent to php. If you are using jquery, use FormData(). For example

<form id='form'>
<input type='file' name='file' />
<input type='submit' />
</form>

Using jquery,

$('#form').submit(function (e) {
e.preventDefault();
var formData = new FormData(this); // grab all form contents including files
//you can then use formData and pass to ajax

});

You can't query against the DataTable's Rows collection, since DataRowCollection doesn't implement IEnumerable<T>. You need to use the AsEnumerable() extension for DataTable. Like so:

var results = from myRow in myDataTable.AsEnumerable()
where myRow.Field<int>("RowNo") == 1
select myRow;

And as @Keith says, you'll need to add a reference to System.Data.DataSetExtensions

AsEnumerable() returns IEnumerable<DataRow>. If you need to convert IEnumerable<DataRow> to a DataTable, use the CopyToDataTable() extension.

Below is query with Lambda Expression,

var result = myDataTable
    .AsEnumerable()
    .Where(myRow => myRow.Field<int>("RowNo") == 1);

To get a meaningful/useful view of the two tables, you normally need to determine an identifying field from each table that can then be used in the ON clause in a JOIN.

THen in your view:

SELECT T1.*, T2.* FROM T1 JOIN T2 ON T1.IDFIELD1 = T2.IDFIELD2

You mention no fields are "common", but although the identifying fields may not have the same name or even be the same data type, you could use the convert / cast functions to join them in some way.

this works for me every time try this.

echo "<font color='blue'>".$myvariable."</font>";

since font is not supported in html5 you can do this

echo "<p class="variablecolor">".$myvariable."</p>";

then in css do

.variablecolor{
color: blue;}

after you get the response just do call this function to append data to your body element

function createDiv(responsetext)
{
    var _body = document.getElementsByTagName('body')[0];
    var _div = document.createElement('div');
    _div.innerHTML = responsetext;
    _body.appendChild(_div);
}

@satya code modified as below

function httpGet(theUrl)
{
    if (window.XMLHttpRequest)
    {// code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
    }
    else
    {// code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange=function()
    {
        if (xmlhttp.readyState==4 && xmlhttp.status==200)
        {
            createDiv(xmlhttp.responseText);
        }
    }
    xmlhttp.open("GET", theUrl, false);
    xmlhttp.send();    
}

<div class="parent" style="height:500px;">
<div class="child-left floatLeft" style="height:100%">
</div>

<div class="child-right floatLeft" style="height:100%">
</div>
</div>

I used inline style just to give idea.

Just for reference, here is a list of all the available properties for a printer ManagementObject.

1. I had the same problem when I started to used babel... But later, I had a solution... I haven't had the problem anymore so far... Currently, Node v12.14.1, "@babel/node": "^7.8.4", I use babel-node and nodemon to execute (node is fine as well..)
2. package.json: "start": "nodemon --exec babel-node server.js "debug": "babel-node debug server.js" !!note: server.js is my entry file, you can use yours.
3. launch.json When you debug, you also need to config your launch.json file "runtimeExecutable": "${workspaceRoot}/node_modules/.bin/babel-node" !!note: plus runtimeExecutable into the configuration.
4. Of course, with babel-node, you also normally need and edit another file, such as babel.config.js/.babelrc file

You can use Array.forEach

var myArray = ['1','2',3,4]_x000D_
_x000D_
myArray.forEach(function(value){_x000D_
  console.log(value);_x000D_
});

start all daemons and run the command as "hadoop namenode -recover -force" stop the daemons and start again.. wait some time to recover data.

Page content can be displayed easily and perfectly this way:

<?php if(have_posts()) : ?>
    <?php while(have_posts())  : the_post(); ?>
      <h2><?php the_title(); ?></h2>                        
      <?php the_content(); ?>          
      <?php comments_template( '', true ); ?> 
    <?php endwhile; ?>                   
      <?php else : ?>                       
        <h3><?php _e('404 Error&#58; Not Found'); ?></h3>
<?php endif; ?>         

Note:

In terms of displaying content - i) comments_template() function is an optional use if you need to enable commenting with different functionality.

ii) _e() function is also optional but more meaningful & effective than just showing text through <p>. while preferred stylized 404.php can be created to be redirected.

impossible with javascript. Just as another alternative to suggestions from other answers: consider using jGrowl: http://archive.plugins.jquery.com/project/jGrowl

In my case it happens when introducing host with templates, graphs,trigger etc, the server falls. The problem was that by default the cache is at 128k and you have to change it.

sudo nano /etc/zabbix/zabbix-server.conf

Uncheck # Sizecache and add 32M for example.

Cachesize=32M

restart service and voila!! server working

service zabbix-server start

You are trying to do a logarithm of something that is not positive.

Logarithms figure out the base after being given a number and the power it was raised to. log(0) means that something raised to the power of 2 is 0. An exponent can never result in 0*, which means that log(0) has no answer, thus throwing the math domain error

*Note: 0^0 can result in 0, but can also result in 1 at the same time. This problem is heavily argued over.

Use the dos2unix command in linux to convert the saved file. example :

Why would you make it VARCHAR? It doesn't vary. It's always 64 characters, which can be determined by running anything into one of the online SHA-256 calculators.

If you want to solve it in a two-liner you can do it like this:

with open('data.json') as f:
    data = [json.loads(line) for line in f]

I had to reinstall webpack to get it working with my local version of webpack, e.g:

$ npm uninstall webpack
$ npm i -D webpack

See:

• JLS 8.7, Static Initializers
• JLS 12.2, Loading of Classes and Interfaces
• JLS 12.4, Initialization of Classes and Interfaces

The last in particular provides detailed initialization steps that spell out when static variables are initialized, and in what order (with the caveat that final class variables and interface fields that are compile-time constants are initialized first.)

I'm not sure what your specific question about point 3 (assuming you mean the nested one?) is. The detailed sequence states this would be a recursive initialization request so it will continue initialization.

int max = items.Max(i => i.ID);
var item = items.First(x => x.ID == max);

This assumes there are elements in the items collection of course.

I used CRAN package "downloader" found at http://cran.r-project.org/web/packages/downloader/index.html . Much easier.

download(url, dest="dataset.zip", mode="wb") 
unzip ("dataset.zip", exdir = "./")

Here's one sample: http://jsfiddle.net/CUUfb/1/

I always write a default method "findByIdOrError" in widely used CrudRepository repos/interfaces.

@Repository 
public interface RequestRepository extends CrudRepository<Request, Integer> {

    default Request findByIdOrError(Integer id) {
        return findById(id).orElseThrow(EntityNotFoundException::new);
    } 
}

Check indexed function from Nspl:

use function \nspl\a\indexed;

Great solution by jAndy, but the smooth scroll seems to be having issues working in firefox.

Writing it this way works in Firefox as well.

(function($) {
    $(document).ready(function() {
         $('html, body').animate({
           'scrollTop':   $('#anchorName2').offset().top
         }, 2000);
    });
})(jQuery);

As others have noted, in Notepad++ 6.0 and later, it is possible to use the "Replace" feature to delete all lines that begin with ";" or "#".

Tao provides a regular expression that serves as a starting point, but it does not account for white-space that may exist before the ";" or "#" character on a given line. For example, lines that begin with ";" or "#" but are "tabbed-in" will not be deleted when using Tao's regular expression, ^(#|;).*\r\n.

Tao's regular expression does not account for the caveat mentioned in BoltClock's answer, either: variances in newline characters across systems.

An improvement is to use ^(\s)*(#|;).*(\r\n|\r|\n)?, which accounts for leading white-space and the newline character variances. Also, the trailing ? handles cases in which the last line of the file begins with # or ;, but does not end with a newline.

For the curious, it is possible to discern which type of newline character is used in a given document (and more than one type may be used): View -> Show Symbol -> Show End of Line.

** Update ** A scalars converter has been added to retrofit that allows for a String response with less ceremony than my original answer below.

Example interface --

public interface GitHubService {
    @GET("/users/{user}")
    Call<String> listRepos(@Path("user") String user);
}

Add the ScalarsConverterFactory to your retrofit builder. Note: If using ScalarsConverterFactory and another factory, add the scalars factory first.

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(BASE_URL)
    .addConverterFactory(ScalarsConverterFactory.create())
    // add other factories here, if needed.
    .build();

You will also need to include the scalars converter in your gradle file --

implementation 'com.squareup.retrofit2:converter-scalars:2.1.0'

--- Original Answer (still works, just more code) ---

I agree with @CommonsWare that it seems a bit odd that you want to intercept the request to process the JSON yourself. Most of the time the POJO has all the data you need, so no need to mess around in JSONObject land. I suspect your specific problem might be better solved using a custom gson TypeAdapter or a retrofit Converter if you need to manipulate the JSON. However, retrofit provides more the just JSON parsing via Gson. It also manages a lot of the other tedious tasks involved in REST requests. Just because you don't want to use one of the features, doesn't mean you have to throw the whole thing out. There are times you just want to get the raw stream, so here is how to do it -

First, if you are using Retrofit 2, you should start using the Call API. Instead of sending an object to convert as the type parameter, use ResponseBody from okhttp --

public interface GitHubService {
    @GET("/users/{user}")
    Call<ResponseBody> listRepos(@Path("user") String user);
}

then you can create and execute your call --

GitHubService service = retrofit.create(GitHubService.class);
Call<ResponseBody> result = service.listRepos(username);
result.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Response<ResponseBody> response) {
        try {
            System.out.println(response.body().string());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onFailure(Throwable t) {
        e.printStackTrace();
    }
});

Note The code above calls string() on the response object, which reads the entire response into a String. If you are passing the body off to something that can ingest streams, you can call charStream() instead. See the ResponseBody docs.

If you google. "Count down for loop python" you get these, which are pretty accurate.

A simple solution is to use writeFile :

require("fs").writeFile(
     somepath,
     arr.map(function(v){ return v.join(', ') }).join('\n'),
     function (err) { console.log(err ? 'Error :'+err : 'ok') }
);

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt


def butter_lowpass(cutoff, fs, order=5):
    nyq = 0.5 * fs
    normal_cutoff = cutoff / nyq
    b, a = butter(order, normal_cutoff, btype='low', analog=False)
    return b, a

def butter_lowpass_filter(data, cutoff, fs, order=5):
    b, a = butter_lowpass(cutoff, fs, order=order)
    y = lfilter(b, a, data)
    return y


# Filter requirements.
order = 6
fs = 30.0       # sample rate, Hz
cutoff = 3.667  # desired cutoff frequency of the filter, Hz

# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)

# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()


# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0         # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data.  We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)

plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()

plt.subplots_adjust(hspace=0.35)
plt.show()

Setting the Hadoop_Home environment variable in system properties didn't work for me. But this did:

• Set the Hadoop_Home in the Eclipse Run Configurations environment tab.
• Follow the 'Windows Environment Setup' from here

Here seems to be an even better answer with 'in' clause that allows for multiple keys for the join:

update fp_active set STATE='E', 
   LAST_DATE_MAJ = sysdate where (client,code) in (select (client,code) from fp_detail
  where valid = 1) ...

The full example is here: http://forums.devshed.com/oracle-development-96/how-to-update-from-two-tables-195893.html - from web archive since link was dead.

The beef is in having the columns that you want to use as the key in parentheses in the where clause before 'in' and have the select statement with the same column names in parentheses. where (column1,column2) in ( select (column1,column2) from table where "the set I want" );

Try CTR + M it will work like before.

The correct thing to do is use the 'string-escape' code to decode the string.

>>> myString = "spam\\neggs"
>>> decoded_string = bytes(myString, "utf-8").decode("unicode_escape") # python3 
>>> decoded_string = myString.decode('string_escape') # python2
>>> print(decoded_string)
spam
eggs

Don't use the AST or eval. Using the string codecs is much safer.

First of all read in the data, then convert it to byte array:

and then use String constructor:

or if the charset is not system default then:

new String(byte[] bytes, String charsetName)

The solution that worked for me: just restart the studio.

Here is one very simple solution for this problem. We have starting date, end date and "for loop" for encreasing the day and calculating to see if it's a workday or a weekend by converting to string DayOfWeek.

@MrBean - I was in a similar situation where I had to call a 3rd-party web service and pass in the Android device's current timezone offset in the format +/-hh:mm. Here is my solution:

public static String getCurrentTimezoneOffset() {

    TimeZone tz = TimeZone.getDefault();  
    Calendar cal = GregorianCalendar.getInstance(tz);
    int offsetInMillis = tz.getOffset(cal.getTimeInMillis());

    String offset = String.format("%02d:%02d", Math.abs(offsetInMillis / 3600000), Math.abs((offsetInMillis / 60000) % 60));
    offset = (offsetInMillis >= 0 ? "+" : "-") + offset;

    return offset;
} 

TOPIC:: topic is one to many communication... (multipoint or publish/subscribe) EX:-imagine a publisher publishes the movie in the youtub then all its subscribers will gets notification.... QUEVE::queve is one-to-one communication ... Ex:-When publish a request for recharge it will go to only one qreciever ... always remember if request goto all qreceivers then multiple recharge happened so while developing analyze which is fit for a application

For Selenium WebDriver using XPath (if the key is visible):

driver.findElement(By.xpath("xpath of text field")).sendKeys(Keys.ENTER);

or,

driver.findElement(By.xpath("xpath of text field")).sendKeys(Keys.RETURN);

You can't put a div directly inside a table, like this:

<!-- INVALID -->
<table>
  <div>
    Hello World
  </div>
</table>

Putting a div inside a td or th element is fine, however:

<!-- VALID -->
<table>
  <tr>
    <td>
      <div>
        Hello World
      </div>
    </td>
  </tr>
</table>

I don't see any problem, unless you are not managing them using a connection pool.

If you use connection pool, these connections are re-used instead of initiating new connections. so basically, leaving open connections and re-use them it is less problematic than re-creating them each time.

Finding unique Array values in simple method

function arrUnique(a){
  var t = [];
  for(var x = 0; x < a.length; x++){
    if(t.indexOf(a[x]) == -1)t.push(a[x]);
  }
  return t;
}
arrUnique([1,4,2,7,1,5,9,2,4,7,2]) // [1, 4, 2, 7, 5, 9]
