First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.

Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.

Instead, I would move all of the "application" content to a separate component, like a JPanel for example and simply move this between the applet or frame as required...

ps- You can use f.setLocationRelativeTo(null) to center the window on the screen ;)

Updated

You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...

Within the constructor of GalzyTable2 you are doing...

JApplet app = new JApplet(); add(app); app.init(); app.start(); 

...Why are you adding another applet to an applet??

Case in point...

Within the main method, you are trying to add the instance of JFrame to itself...

f.getContentPane().add(f, button2); 

Instead, create yourself a class that extends from something like JPanel, add your UI logical to this, using compound components if required.

Then, add this panel to whatever top level container you need.

If you think a 64-bit DIV instruction is a good way to divide by two, then no wonder the compiler's asm output beat your hand-written code, even with -O0 (compile fast, no extra optimization, and store/reload to memory after/before every C statement so a debugger can modify variables).

See Agner Fog's Optimizing Assembly guide to learn how to write efficient asm. He also has instruction tables and a microarch guide for specific details for specific CPUs. See also the x86 tag wiki for more perf links.

See also this more general question about beating the compiler with hand-written asm: Is inline assembly language slower than native C++ code?. TL:DR: yes if you do it wrong (like this question).

Usually you're fine letting the compiler do its thing, especially if you try to write C++ that can compile efficiently. Also see is assembly faster than compiled languages?. One of the answers links to these neat slides showing how various C compilers optimize some really simple functions with cool tricks. Matt Godbolt's CppCon2017 talk “What Has My Compiler Done for Me Lately? Unbolting the Compiler's Lid” is in a similar vein.

even:
    mov rbx, 2
    xor rdx, rdx
    div rbx

On Intel Haswell, div r64 is 36 uops, with a latency of 32-96 cycles, and a throughput of one per 21-74 cycles. (Plus the 2 uops to set up RBX and zero RDX, but out-of-order execution can run those early). High-uop-count instructions like DIV are microcoded, which can also cause front-end bottlenecks. In this case, latency is the most relevant factor because it's part of a loop-carried dependency chain.

shr rax, 1 does the same unsigned division: It's 1 uop, with 1c latency, and can run 2 per clock cycle.

For comparison, 32-bit division is faster, but still horrible vs. shifts. idiv r32 is 9 uops, 22-29c latency, and one per 8-11c throughput on Haswell.

As you can see from looking at gcc's -O0 asm output (Godbolt compiler explorer), it only uses shifts instructions. clang -O0 does compile naively like you thought, even using 64-bit IDIV twice. (When optimizing, compilers do use both outputs of IDIV when the source does a division and modulus with the same operands, if they use IDIV at all)

GCC doesn't have a totally-naive mode; it always transforms through GIMPLE, which means some "optimizations" can't be disabled. This includes recognizing division-by-constant and using shifts (power of 2) or a fixed-point multiplicative inverse (non power of 2) to avoid IDIV (see div_by_13 in the above godbolt link).

gcc -Os (optimize for size) does use IDIV for non-power-of-2 division, unfortunately even in cases where the multiplicative inverse code is only slightly larger but much faster.

Helping the compiler

(summary for this case: use uint64_t n)

First of all, it's only interesting to look at optimized compiler output. (-O3). -O0 speed is basically meaningless.

Look at your asm output (on Godbolt, or see How to remove "noise" from GCC/clang assembly output?). When the compiler doesn't make optimal code in the first place: Writing your C/C++ source in a way that guides the compiler into making better code is usually the best approach. You have to know asm, and know what's efficient, but you apply this knowledge indirectly. Compilers are also a good source of ideas: sometimes clang will do something cool, and you can hand-hold gcc into doing the same thing: see this answer and what I did with the non-unrolled loop in @Veedrac's code below.)

This approach is portable, and in 20 years some future compiler can compile it to whatever is efficient on future hardware (x86 or not), maybe using new ISA extension or auto-vectorizing. Hand-written x86-64 asm from 15 years ago would usually not be optimally tuned for Skylake. e.g. compare&branch macro-fusion didn't exist back then. What's optimal now for hand-crafted asm for one microarchitecture might not be optimal for other current and future CPUs. Comments on @johnfound's answer discuss major differences between AMD Bulldozer and Intel Haswell, which have a big effect on this code. But in theory, g++ -O3 -march=bdver3 and g++ -O3 -march=skylake will do the right thing. (Or -march=native.) Or -mtune=... to just tune, without using instructions that other CPUs might not support.

My feeling is that guiding the compiler to asm that's good for a current CPU you care about shouldn't be a problem for future compilers. They're hopefully better than current compilers at finding ways to transform code, and can find a way that works for future CPUs. Regardless, future x86 probably won't be terrible at anything that's good on current x86, and the future compiler will avoid any asm-specific pitfalls while implementing something like the data movement from your C source, if it doesn't see something better.

Hand-written asm is a black-box for the optimizer, so constant-propagation doesn't work when inlining makes an input a compile-time constant. Other optimizations are also affected. Read https://gcc.gnu.org/wiki/DontUseInlineAsm before using asm. (And avoid MSVC-style inline asm: inputs/outputs have to go through memory which adds overhead.)

In this case: your n has a signed type, and gcc uses the SAR/SHR/ADD sequence that gives the correct rounding. (IDIV and arithmetic-shift "round" differently for negative inputs, see the SAR insn set ref manual entry). (IDK if gcc tried and failed to prove that n can't be negative, or what. Signed-overflow is undefined behaviour, so it should have been able to.)

You should have used uint64_t n, so it can just SHR. And so it's portable to systems where long is only 32-bit (e.g. x86-64 Windows).

BTW, gcc's optimized asm output looks pretty good (using unsigned long n): the inner loop it inlines into main() does this:

 # from gcc5.4 -O3  plus my comments

 # edx= count=1
 # rax= uint64_t n

.L9:                   # do{
    lea    rcx, [rax+1+rax*2]   # rcx = 3*n + 1
    mov    rdi, rax
    shr    rdi         # rdi = n>>1;
    test   al, 1       # set flags based on n%2 (aka n&1)
    mov    rax, rcx
    cmove  rax, rdi    # n= (n%2) ? 3*n+1 : n/2;
    add    edx, 1      # ++count;
    cmp    rax, 1
    jne   .L9          #}while(n!=1)

  cmp/branch to update max and maxi, and then do the next n

The inner loop is branchless, and the critical path of the loop-carried dependency chain is:

• 3-component LEA (3 cycles)
• cmov (2 cycles on Haswell, 1c on Broadwell or later).

Total: 5 cycle per iteration, latency bottleneck. Out-of-order execution takes care of everything else in parallel with this (in theory: I haven't tested with perf counters to see if it really runs at 5c/iter).

The FLAGS input of cmov (produced by TEST) is faster to produce than the RAX input (from LEA->MOV), so it's not on the critical path.

Similarly, the MOV->SHR that produces CMOV's RDI input is off the critical path, because it's also faster than the LEA. MOV on IvyBridge and later has zero latency (handled at register-rename time). (It still takes a uop, and a slot in the pipeline, so it's not free, just zero latency). The extra MOV in the LEA dep chain is part of the bottleneck on other CPUs.

The cmp/jne is also not part of the critical path: it's not loop-carried, because control dependencies are handled with branch prediction + speculative execution, unlike data dependencies on the critical path.

Beating the compiler

GCC did a pretty good job here. It could save one code byte by using inc edx instead of add edx, 1, because nobody cares about P4 and its false-dependencies for partial-flag-modifying instructions.

It could also save all the MOV instructions, and the TEST: SHR sets CF= the bit shifted out, so we can use cmovc instead of test / cmovz.

 ### Hand-optimized version of what gcc does
.L9:                       #do{
    lea     rcx, [rax+1+rax*2] # rcx = 3*n + 1
    shr     rax, 1         # n>>=1;    CF = n&1 = n%2
    cmovc   rax, rcx       # n= (n&1) ? 3*n+1 : n/2;
    inc     edx            # ++count;
    cmp     rax, 1
    jne     .L9            #}while(n!=1)

See @johnfound's answer for another clever trick: remove the CMP by branching on SHR's flag result as well as using it for CMOV: zero only if n was 1 (or 0) to start with. (Fun fact: SHR with count != 1 on Nehalem or earlier causes a stall if you read the flag results. That's how they made it single-uop. The shift-by-1 special encoding is fine, though.)

Avoiding MOV doesn't help with the latency at all on Haswell (Can x86's MOV really be "free"? Why can't I reproduce this at all?). It does help significantly on CPUs like Intel pre-IvB, and AMD Bulldozer-family, where MOV is not zero-latency. The compiler's wasted MOV instructions do affect the critical path. BD's complex-LEA and CMOV are both lower latency (2c and 1c respectively), so it's a bigger fraction of the latency. Also, throughput bottlenecks become an issue, because it only has two integer ALU pipes. See @johnfound's answer, where he has timing results from an AMD CPU.

Even on Haswell, this version may help a bit by avoiding some occasional delays where a non-critical uop steals an execution port from one on the critical path, delaying execution by 1 cycle. (This is called a resource conflict). It also saves a register, which may help when doing multiple n values in parallel in an interleaved loop (see below).

LEA's latency depends on the addressing mode, on Intel SnB-family CPUs. 3c for 3 components ([base+idx+const], which takes two separate adds), but only 1c with 2 or fewer components (one add). Some CPUs (like Core2) do even a 3-component LEA in a single cycle, but SnB-family doesn't. Worse, Intel SnB-family standardizes latencies so there are no 2c uops, otherwise 3-component LEA would be only 2c like Bulldozer. (3-component LEA is slower on AMD as well, just not by as much).

So lea rcx, [rax + rax*2] / inc rcx is only 2c latency, faster than lea rcx, [rax + rax*2 + 1], on Intel SnB-family CPUs like Haswell. Break-even on BD, and worse on Core2. It does cost an extra uop, which normally isn't worth it to save 1c latency, but latency is the major bottleneck here and Haswell has a wide enough pipeline to handle the extra uop throughput.

Neither gcc, icc, nor clang (on godbolt) used SHR's CF output, always using an AND or TEST. Silly compilers. :P They're great pieces of complex machinery, but a clever human can often beat them on small-scale problems. (Given thousands to millions of times longer to think about it, of course! Compilers don't use exhaustive algorithms to search for every possible way to do things, because that would take too long when optimizing a lot of inlined code, which is what they do best. They also don't model the pipeline in the target microarchitecture, at least not in the same detail as IACA or other static-analysis tools; they just use some heuristics.)

Simple loop unrolling won't help; this loop bottlenecks on the latency of a loop-carried dependency chain, not on loop overhead / throughput. This means it would do well with hyperthreading (or any other kind of SMT), since the CPU has lots of time to interleave instructions from two threads. This would mean parallelizing the loop in main, but that's fine because each thread can just check a range of n values and produce a pair of integers as a result.

Interleaving by hand within a single thread might be viable, too. Maybe compute the sequence for a pair of numbers in parallel, since each one only takes a couple registers, and they can all update the same max / maxi. This creates more instruction-level parallelism.

The trick is deciding whether to wait until all the n values have reached 1 before getting another pair of starting n values, or whether to break out and get a new start point for just one that reached the end condition, without touching the registers for the other sequence. Probably it's best to keep each chain working on useful data, otherwise you'd have to conditionally increment its counter.

You could maybe even do this with SSE packed-compare stuff to conditionally increment the counter for vector elements where n hadn't reached 1 yet. And then to hide the even longer latency of a SIMD conditional-increment implementation, you'd need to keep more vectors of n values up in the air. Maybe only worth with 256b vector (4x uint64_t).

I think the best strategy to make detection of a 1 "sticky" is to mask the vector of all-ones that you add to increment the counter. So after you've seen a 1 in an element, the increment-vector will have a zero, and +=0 is a no-op.

Untested idea for manual vectorization

# starting with YMM0 = [ n_d, n_c, n_b, n_a ]  (64-bit elements)
# ymm4 = _mm256_set1_epi64x(1):  increment vector
# ymm5 = all-zeros:  count vector

.inner_loop:
    vpaddq    ymm1, ymm0, xmm0
    vpaddq    ymm1, ymm1, xmm0
    vpaddq    ymm1, ymm1, set1_epi64(1)     # ymm1= 3*n + 1.  Maybe could do this more efficiently?

    vprllq    ymm3, ymm0, 63                # shift bit 1 to the sign bit

    vpsrlq    ymm0, ymm0, 1                 # n /= 2

    # FP blend between integer insns may cost extra bypass latency, but integer blends don't have 1 bit controlling a whole qword.
    vpblendvpd ymm0, ymm0, ymm1, ymm3       # variable blend controlled by the sign bit of each 64-bit element.  I might have the source operands backwards, I always have to look this up.

    # ymm0 = updated n  in each element.

    vpcmpeqq ymm1, ymm0, set1_epi64(1)
    vpandn   ymm4, ymm1, ymm4         # zero out elements of ymm4 where the compare was true

    vpaddq   ymm5, ymm5, ymm4         # count++ in elements where n has never been == 1

    vptest   ymm4, ymm4
    jnz  .inner_loop
    # Fall through when all the n values have reached 1 at some point, and our increment vector is all-zero

    vextracti128 ymm0, ymm5, 1
    vpmaxq .... crap this doesn't exist
    # Actually just delay doing a horizontal max until the very very end.  But you need some way to record max and maxi.

You can and should implement this with intrinsics instead of hand-written asm.

Algorithmic / implementation improvement:

Besides just implementing the same logic with more efficient asm, look for ways to simplify the logic, or avoid redundant work. e.g. memoize to detect common endings to sequences. Or even better, look at 8 trailing bits at once (gnasher's answer)

@EOF points out that tzcnt (or bsf) could be used to do multiple n/=2 iterations in one step. That's probably better than SIMD vectorizing; no SSE or AVX instruction can do that. It's still compatible with doing multiple scalar ns in parallel in different integer registers, though.

So the loop might look like this:

goto loop_entry;  // C++ structured like the asm, for illustration only
do {
   n = n*3 + 1;
  loop_entry:
   shift = _tzcnt_u64(n);
   n >>= shift;
   count += shift;
} while(n != 1);

This may do significantly fewer iterations, but variable-count shifts are slow on Intel SnB-family CPUs without BMI2. 3 uops, 2c latency. (They have an input dependency on the FLAGS because count=0 means the flags are unmodified. They handle this as a data dependency, and take multiple uops because a uop can only have 2 inputs (pre-HSW/BDW anyway)). This is the kind that people complaining about x86's crazy-CISC design are referring to. It makes x86 CPUs slower than they would be if the ISA was designed from scratch today, even in a mostly-similar way. (i.e. this is part of the "x86 tax" that costs speed / power.) SHRX/SHLX/SARX (BMI2) are a big win (1 uop / 1c latency).

It also puts tzcnt (3c on Haswell and later) on the critical path, so it significantly lengthens the total latency of the loop-carried dependency chain. It does remove any need for a CMOV, or for preparing a register holding n>>1, though. @Veedrac's answer overcomes all this by deferring the tzcnt/shift for multiple iterations, which is highly effective (see below).

We can safely use BSF or TZCNT interchangeably, because n can never be zero at that point. TZCNT's machine-code decodes as BSF on CPUs that don't support BMI1. (Meaningless prefixes are ignored, so REP BSF runs as BSF).

TZCNT performs much better than BSF on AMD CPUs that support it, so it can be a good idea to use REP BSF, even if you don't care about setting ZF if the input is zero rather than the output. Some compilers do this when you use __builtin_ctzll even with -mno-bmi.

They perform the same on Intel CPUs, so just save the byte if that's all that matters. TZCNT on Intel (pre-Skylake) still has a false-dependency on the supposedly write-only output operand, just like BSF, to support the undocumented behaviour that BSF with input = 0 leaves its destination unmodified. So you need to work around that unless optimizing only for Skylake, so there's nothing to gain from the extra REP byte. (Intel often goes above and beyond what the x86 ISA manual requires, to avoid breaking widely-used code that depends on something it shouldn't, or that is retroactively disallowed. e.g. Windows 9x's assumes no speculative prefetching of TLB entries, which was safe when the code was written, before Intel updated the TLB management rules.)

Anyway, LZCNT/TZCNT on Haswell have the same false dep as POPCNT: see this Q&A. This is why in gcc's asm output for @Veedrac's code, you see it breaking the dep chain with xor-zeroing on the register it's about to use as TZCNT's destination when it doesn't use dst=src. Since TZCNT/LZCNT/POPCNT never leave their destination undefined or unmodified, this false dependency on the output on Intel CPUs is a performance bug / limitation. Presumably it's worth some transistors / power to have them behave like other uops that go to the same execution unit. The only perf upside is interaction with another uarch limitation: they can micro-fuse a memory operand with an indexed addressing mode on Haswell, but on Skylake where Intel removed the false dep for LZCNT/TZCNT they "un-laminate" indexed addressing modes while POPCNT can still micro-fuse any addr mode.

Improvements to ideas / code from other answers:

@hidefromkgb's answer has a nice observation that you're guaranteed to be able to do one right shift after a 3n+1. You can compute this more even more efficiently than just leaving out the checks between steps. The asm implementation in that answer is broken, though (it depends on OF, which is undefined after SHRD with a count > 1), and slow: ROR rdi,2 is faster than SHRD rdi,rdi,2, and using two CMOV instructions on the critical path is slower than an extra TEST that can run in parallel.

I put tidied / improved C (which guides the compiler to produce better asm), and tested+working faster asm (in comments below the C) up on Godbolt: see the link in @hidefromkgb's answer. (This answer hit the 30k char limit from the large Godbolt URLs, but shortlinks can rot and were too long for goo.gl anyway.)

Also improved the output-printing to convert to a string and make one write() instead of writing one char at a time. This minimizes impact on timing the whole program with perf stat ./collatz (to record performance counters), and I de-obfuscated some of the non-critical asm.

@Veedrac's code

I got a minor speedup from right-shifting as much as we know needs doing, and checking to continue the loop. From 7.5s for limit=1e8 down to 7.275s, on Core2Duo (Merom), with an unroll factor of 16.

code + comments on Godbolt. Don't use this version with clang; it does something silly with the defer-loop. Using a tmp counter k and then adding it to count later changes what clang does, but that slightly hurts gcc.

See discussion in comments: Veedrac's code is excellent on CPUs with BMI1 (i.e. not Celeron/Pentium)

1) First Insert JS file path in an index.html file :

<script src="assets/video.js" type="text/javascript"></script>

2) Import JS file and declare the variable in component.ts :

• import './../../../assets/video.js';

• declare var RunPlayer: any;

  NOTE: Variable name should be same as the name of a function in js file

3) Call the js method in the component

ngAfterViewInit(){

    setTimeout(() => {
        new RunPlayer();
    });

}

If you are using any layout page then, move script sections from bottom to head section in layout page. bcz, javascript files should be loaded first. This worked for me

The best way to boost up android studio runtime performance is to use SSD Drive. It will boost the performance as very much. I did all the above things and felt I should go for new laptop, but suddenly I came to know about SSD Drive and I tried it. Its Much Much better.....

Take a look at PyCrypto. It supports Python 3.2 and does exactly what you want.

From their pip website:

>>> from Crypto.Cipher import AES
>>> obj = AES.new('This is a key123', AES.MODE_CFB, 'This is an IV456')
>>> message = "The answer is no"
>>> ciphertext = obj.encrypt(message)
>>> ciphertext
'\xd6\x83\x8dd!VT\x92\xaa`A\x05\xe0\x9b\x8b\xf1'
>>> obj2 = AES.new('This is a key123', AES.MODE_CFB, 'This is an IV456')
>>> obj2.decrypt(ciphertext)
'The answer is no'

If you want to encrypt a message of an arbitrary size use AES.MODE_CFB instead of AES.MODE_CBC.

Keep in mind that docker ps --size may be an expensive command, taking more than a few minutes to complete. The same applies to container list API requests with size=1. It's better not to run it too often.

Take a look at alternatives we compiled, including the du -hs option for the docker persistent volume directory.

I have tested by making a sample project and all simulators seem to use @3x images , this is confusing.

Create different versions of an image in your asset catalog such that the image itself tells you what version it is:

Now run the app on each simulator in turn. You will see that the 3x image is used only on the iPhone 6 Plus.

The same thing is true if the images are drawn from the app bundle using their names (e.g. one.png, [email protected], and [email protected]) by calling imageNamed: and assigning into an image view.

(However, there's a difference if you assign the image to an image view in Interface Builder - the 2x version is ignored on double-resolution devices. This is presumably a bug, apparently a bug in pathForResource:ofType:.)

You can use the following code snippet :

java -XX:+PrintFlagsFinal -Xms512m -Xmx1024m -Xss512k -XX:PermSize=64m -XX:MaxPermSize=128m
    -version | grep -iE 'HeapSize|PermSize|ThreadStackSize'

In my pc I am getting following output :

    uintx InitialHeapSize                          := 536870912       {product}
    uintx MaxHeapSize                              := 1073741824      {product}
    uintx PermSize                                 := 67108864        {pd product}
    uintx MaxPermSize                              := 134217728       {pd product}
     intx ThreadStackSize                          := 512             {pd product}

Use FileSaver.js. It supports Chrome, Edge, Firefox, and IE 10+ (and probably IE < 10 with a few "polyfills" - see Note 4). FileSaver.js implements the saveAs() FileSaver interface in browsers that do not natively support it:
     https://github.com/eligrey/FileSaver.js

Minified version is really small at < 2.5KB, gzipped < 1.2KB.

Usage:

/* TODO: replace the blob content with your byte[] */
var blob = new Blob([yourBinaryDataAsAnArrayOrAsAString], {type: "application/octet-stream"});
var fileName = "myFileName.myExtension";
saveAs(blob, fileName);

You might need Blob.js in some browsers (see Note 3). Blob.js implements the W3C Blob interface in browsers that do not natively support it. It is a cross-browser implementation:
     https://github.com/eligrey/Blob.js

Consider StreamSaver.js if you have files larger than blob's size limitations.

Here is a component that incorporates much of this by lovasoa: https://github.com/lovasoa/react-contenteditable/blob/master/index.js

He shims the event in the emitChange

emitChange: function(evt){
    var html = this.getDOMNode().innerHTML;
    if (this.props.onChange && html !== this.lastHtml) {
        evt.target = { value: html };
        this.props.onChange(evt);
    }
    this.lastHtml = html;
}

I'm using a similar approach successfully

I ran into same problem. I selected location C:\Program Files (x86)\Android\android-studio\plugins\gradle as Gradle Home

I listen for WifiManager.NETWORK_STATE_CHANGED_ACTION in a broadcast receiver

if (WifiManager.NETWORK_STATE_CHANGED_ACTION.equals (action)) {
        NetworkInfo netInfo = intent.getParcelableExtra (WifiManager.EXTRA_NETWORK_INFO);
        if (ConnectivityManager.TYPE_WIFI == netInfo.getType ()) {

I check for netInfo.isConnected (). Then I am able to use

WifiManager wifiManager = (WifiManager) getSystemService (Context.WIFI_SERVICE);
WifiInfo info = wifiManager.getConnectionInfo ();
String ssid  = info.getSSID();

UPDATE

From android 8.0 onwards we wont be getting SSID of the connected network unless GPS is turned on.

There is a simple and clean way of doing this with only directives.

<div ng-class="{'class-name': clicked}" ng-click="clicked = !clicked"></div>

It's possible that you've run out of memory or some space elsewhere and it prompted the system to mount an overflow filesystem, and for whatever reason, it's not going away.

Try unmounting the overflow partition:

umount /tmp

or

umount overflow

found a solution for scrollview -> viewpager -> FragmentPagerAdapter -> fragment -> dynamic listview, but im not the author. there is some bugs, but at least it works

public class CustomPager extends ViewPager {

    private View mCurrentView;

    public CustomPager(Context context) {
        super(context);
    }

    public CustomPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        if (mCurrentView == null) {
            super.onMeasure(widthMeasureSpec, heightMeasureSpec);
            return;
        }
        int height = 0;
        mCurrentView.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
        int h = mCurrentView.getMeasuredHeight();
        if (h > height) height = h;
        heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);

        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }

    public void measureCurrentView(View currentView) {
        mCurrentView = currentView;
        this.post(new Runnable() {
            @Override
            public void run() {
                requestLayout();
            }
        });
    }

    public int measureFragment(View view) {
        if (view == null)
            return 0;

        view.measure(0, 0);
        return view.getMeasuredHeight();
    }
}


public class MyPagerAdapter extends FragmentPagerAdapter {

    private List<Fragment> fragments;
    private int mCurrentPosition = -1;


    public MyPagerAdapter(FragmentManager fm) {
        super(fm);//or u can set them separately, but dont forget to call notifyDataSetChanged()
        this.fragments = new ArrayList<Fragment>();
        fragments.add(new FirstFragment());
        fragments.add(new SecondFragment());
        fragments.add(new ThirdFragment());
        fragments.add(new FourthFragment());
    }

    @Override
    public void setPrimaryItem(ViewGroup container, int position, Object object) {
        super.setPrimaryItem(container, position, object);
        if (position != mCurrentPosition) {
            Fragment fragment = (Fragment) object;
            CustomPager pager = (CustomPager) container;
            if (fragment != null && fragment.getView() != null) {
                mCurrentPosition = position;
                pager.measureCurrentView(fragment.getView());
            }
        }
    }

    @Override
    public Fragment getItem(int position) {
        return fragments.get(position);
    }

    @Override
    public int getCount() {
        return fragments.size();
    }
}

fragments layout can be anything

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:orientation="vertical"
    android:layout_height="match_parent" tools:context="nevet.me.wcviewpagersample.FirstFragment">


    <ListView
        android:id="@+id/lv1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#991199"/>
</LinearLayout>

then somewhere just

lv = (ListView) view.findViewById(R.id.lv1);
        lv.setAdapter(arrayAdapter);
        setListViewHeightBasedOnChildren(lv);
    }

    public static void setListViewHeightBasedOnChildren(ListView listView) {
        ListAdapter listAdapter = listView.getAdapter();
        if (listAdapter == null)
            return;

        int desiredWidth = View.MeasureSpec.makeMeasureSpec(listView.getWidth(),
                View.MeasureSpec.UNSPECIFIED);
        int totalHeight = 0;
        View view = null;

        }
        ViewGroup.LayoutParams params = listView.getLayoutParams();
        params.height = totalHeight
                + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
        listView.setLayoutParams(params);
        listView.requestLayout();
    }

Based on previous statements, for better performance, you can also add an if condition

if (player.isPlaying() {
    handler.postDelayed(..., 1000);
}

Android Development Tools (ADT) 9.0.0 (or later) has a feature that allows you to save state of the AVD (emulator), and you can start your emulator instantly. You have to enable this feature while creating a new AVD or you can just create it later by editing the AVD.

Also I have increased the Device RAM Size to 1024 which results in a very fast emulator.

Refer the given below screenshots for more information.

Creating a new AVD with the save snapshot feature.

Launching the emulator from the snapshot.

And for speeding up your emulator you can refer to Speed up your Android Emulator!:

The fact that a HTTPS request becomes HTTP when you tried to construct the URL on server side indicates that you might have a proxy/load balancer (nginx, pound, etc.) offloading SSL encryption in front and forward to your back end service in plain HTTP.

If that's case, check,

1. whether your proxy has been set up to forward headers correctly (Host, X-forwarded-proto, X-forwarded-for, etc).
2. whether your service container (E.g. Tomcat) is set up to recognize the proxy in front. For example, Tomcat requires adding secure="true" scheme="https" proxyPort="443" attributes to its Connector
3. whether your code, or service container is processing the headers correctly. For example, Tomcat automatically replaces scheme, remoteAddr, etc. values when you add RemoteIpValve to its Engine. (see Configuration guide, JavaDoc) so you don't have to process these headers in your code manually.

Incorrect proxy header values could result in incorrect output when request.getRequestURI() or request.getRequestURL() attempts to construct the originating URL.

Another approach is to not have the secret on the device in the first place! See Mobile API Security Techniques (especially part 3).

Using the time honored tradition of indirection, share the secret between your API endpoint and an app authentication service.

When your client wants to make an API call, it asks the app auth service to authenticate it (using strong remote attestation techniques), and it receives a time limited (usually JWT) token signed by the secret.

The token is sent with each API call where the endpoint can verify its signature before acting on the request.

The actual secret is never present on the device; in fact, the app never has any idea if it is valid or not, it juts requests authentication and passes on the resulting token. As a nice benefit from indirection, if you ever want to change the secret, you can do so without requiring users to update their installed apps.

So if you want to protect your secret, not having it in your app in the first place is a pretty good way to go.

There is no difference until you compile to same target architecture. I suppose you are compiling for 32 bit architecture in both cases.

It's worth mentioning that OutOfMemoryException can also be raised if you get 2GB of memory allocated by a single collection in CLR (say List<T>) on both architectures 32 and 64 bit.

To be able to benefit from memory goodness on 64 bit architecture, you have to compile your code targeting 64 bit architecture. After that, naturally, your binary will run only on 64 bit, but will benefit from possibility having more space available in RAM.

Try this command, it will help you to get ipaddress

adb shell ifconfig tiwlan0

tiwlan0 is the name of the wi-fi network interface on the device. This is generic command for getting ipaddress,

 adb shell netcfg

It will output like this

usb0     DOWN  0.0.0.0         0.0.0.0         0×00001002
sit0     DOWN  0.0.0.0         0.0.0.0         0×00000080

You can see some reports in SSMS:

Right-click the instance name / reports / standard / top sessions

You can see top CPU consuming sessions. This may shed some light on what SQL processes are using resources. There are a few other CPU related reports if you look around. I was going to point to some more DMVs but if you've looked into that already I'll skip it.

You can use sp_BlitzCache to find the top CPU consuming queries. You can also sort by IO and other things as well. This is using DMV info which accumulates between restarts.

This article looks promising.

Some stackoverflow goodness from Mr. Ozar.

edit: A little more advice... A query running for 'only' 5 seconds can be a problem. It could be using all your cores and really running 8 cores times 5 seconds - 40 seconds of 'virtual' time. I like to use some DMVs to see how many executions have happened for that code to see what that 5 seconds adds up to.

The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:

ffmpeg -i input.mov -qscale 0 output.mp4

Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0):

ffmpeg -i input.mov -q:v 0 output.mp4

Update 2019

In Bootstrap 4, flexbox can be used to get a full height layout that fills the remaining space.

First of all, the container (parent) needs to be full height:

Option 1_ Add a class for min-height: 100%;. Remember that min-height will only work if the parent has a defined height:

html, body {
  height: 100%;
}

.min-100 {
    min-height: 100%;
}

https://codeply.com/go/dTaVyMah1U

Option 2_ Use vh units:

.vh-100 {
    min-height: 100vh;
}

https://codeply.com/go/kMahVdZyGj

Also of Bootstrap 4.1, the vh-100 and min-vh-100 classes are included in Bootstrap so there is no need to for the extra CSS

Then, use flexbox direction column d-flex flex-column on the container, and flex-grow-1 on any child divs (ie: row) that you want to fill the remaining height.

Device name and Machine Names, based on iOS Real Device Hardware

My solution to this issue is basically looks related to @NicolasMiari answer within this thread. Separate utility class has a predefined set of Device and Machine names and then depending on the real machine name, retrieve the Device Name.

Note: This answer and it's linked GitHub project has been updated to identify current latest iPhones (iPhone 8, 8+, X) as of October 2017. And this works on iOS11 too. Please visit the GitHub repo and see, and give me feedback if something is wrong.

They have wrapped most stuff need to solve your problem, one of the tests looks like this:

String filename = CSSURLEmbedderTest.class.getResource("folder.png").getPath().replace("%20", " ");
String code = "background: url(folder.png);";

StringWriter writer = new StringWriter();
embedder = new CSSURLEmbedder(new StringReader(code), true);
embedder.embedImages(writer, filename.substring(0, filename.lastIndexOf("/")+1));

String result = writer.toString();
assertEquals("background: url(" + folderDataURI + ");", result);

It looks like details is an array of hashes. So item inside of your block will be the whole hash. Therefore, to check the :qty key, you'd do something like the following:

details.select{ |item| item[:qty] != "" }

That will give you all items where the :qty key isn't an empty string.

official select documentation

I had the same problem. This problem is easily solved if you issue the Cleanup command from AnkhSVN.

like this?

<?php
$url_endpoint = get_permalink();
$url_endpoint = parse_url( $url_endpoint );
$url_endpoint = $url_endpoint['path'];

header('Location: http://linkhere.com/'. $url_endpoint);

?>

As of now, with Revision 26.1.3 of the android emulator, it is finally possible on the image v8 of the API 25. If the emulator was created before you upgrade to the latest API 25 image, you need to wipe data or simply delete and recreate your image if you prefer.

Added support for Wi-Fi in some system images (currently only API level 25). An access point called "AndroidWifi" is available and Android automatically connects to it. Wi-Fi support can be disabled by running the emulator with the command line parameter -feature -Wifi.

from https://developer.android.com/studio/releases/emulator.html#26-1-3

I guess that the most correct answer is: Use :nth-child (or, in this specific case, its counterpart :nth-last-child). Most only know this selector by its first argument to grab a range of items based on a calculation with n, but it can also take a second argument "of [any CSS selector]".

Your scenario could be solved with this selector: .commentList .comment:nth-last-child(1 of .comment)

But being technically correct doesn't mean you can use it, though, because this selector is as of now only implemented in Safari.

This can be done with cgroups, by combining knowledge from these two articles: https://www.percona.com/blog/2015/07/01/using-cgroups-to-limit-mysql-and-mongodb-memory-usage/

You can find here a small shell script which will create config and init files for Ubuntu 14.04: http://brainsuckerna.blogspot.com.by/2016/05/limiting-mongodb-memory-usage-with.html

I'm looking for the same thing, but all I found was PAW Server.

I haven't tried it but I was told it should work just like a standard AMP install but without the mySQL.

The database is what I'm finding to be a pain. I might just have to use a remote DB and local web server to feed from that, but that will mean I'll need to have it always online.

Here is a snippet that does not need ajQuery and will enable alerts in a disabled iframe (like on codepen)

for (var i = 0; i < document.getElementsByTagName('iframe').length; i++) {
    document.getElementsByTagName('iframe')[i].setAttribute('sandbox','allow-modals');
}

Here is a codepen demo working with an alert() after this fix as well: http://codepen.io/nicholasabrams/pen/vNpoBr?editors=001

I created one more list by sorting Jaspers list by device RAM (I made my own tests with Split's tool and fixed some results - check my comments in Jaspers thread).

device RAM: percent range to crash

• 256MB: 49% - 51%
• 512MB: 53% - 63%
• 1024MB: 57% - 68%
• 2048MB: 68% - 69%
• 3072MB: 63% - 66%
• 4096MB: 77%
• 6144MB: 81%

Special cases:

• iPhone X (3072MB): 50%
• iPhone XS/XS Max (4096MB): 55%
• iPhone XR (3072MB): 63%
• iPhone 11/11 Pro Max (4096MB): 54% - 55%

Device RAM can be read easily:

[NSProcessInfo processInfo].physicalMemory

From my experience it is safe to use 45% for 1GB devices, 50% for 2/3GB devices and 55% for 4GB devices. Percent for macOS can be a bit bigger.

Url addresses must be preceded by http://

Uri uri = Uri.parse("www.google.com");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);

throws an ActivityNotFoundException. If you prepend "http://", problem solved.

Uri uri = Uri.parse("http://www.google.com");

I have a Centos 5 system that I wasn't able to get this working on. So I built a new Fedora 17 system (actually a VM in VMware), and followed the steps at the ffmpeg site to build the latest and greatest ffmpeg.

I took some shortcuts - I skipped all the yum erase commands, added freshrpms according to their instructions:

wget http://ftp.freshrpms.net/pub/freshrpms/fedora/linux/9/freshrpms-release/freshrpms-release-1.1-1.fc.noarch.rpm
rpm -ivh rpmfusion-free-release-stable.noarch.rpm

Then I loaded the stuff that was already readily available:

yum install lame libogg libtheora libvorbis lame-devel libtheora-devel

Afterwards, I only built the following from scratch: libvpx vo-aacenc-0.1.2 x264 yasm-1.2.0 ffmpeg

Then this command encoded with no problems (the audio was already in AAC, so I didn't recode it):

ffmpeg -i input.mov -c:v libx264 -preset slow -crf 22 -c:a copy output.mp4

The result looks just as good as the original to me, and is about 1/4 of the size!

That is, you are referencing an image, but instead of providing an external url, the png image data is in the url itself, embedded in the style sheet. data:image/png;base64 tells the browser that the data is inline, is a png image and is in this case base64 encoded. The encoding is needed because png images can contain bytes that are invalid inside a HTML document (or within the HTTP protocol even).

I had the same error on Kitkat which was because i had android:tint on one of the imageViews. It would work fine on Lollipop but crash on Kikkat with Error Inflating class .

Fixed it by using app:tint on the AppCompatImageView which i was dealing with.

It really depends on what functions you're using to plot the lines, but try see if the on you're using takes an alpha value and set it to something like 0.5. If that doesn't work, try get the line objects and set their alpha values directly.

The NetworkInfo class is deprecated as of API level 29, along with the related access methods like ConnectivityManager#getNetworkInfo() and ConnectivityManager#getActiveNetworkInfo().

The documentation now suggests people to use the ConnectivityManager.NetworkCallback API for asynchronized callback monitoring, or use ConnectivityManager#getNetworkCapabilities or ConnectivityManager#getLinkProperties for synchronized access of network information

Callers should instead use the ConnectivityManager.NetworkCallback API to learn about connectivity changes, or switch to use ConnectivityManager#getNetworkCapabilities or ConnectivityManager#getLinkProperties to get information synchronously.

To check if WiFi is connected, here's the code that I use:

Kotlin:

val connMgr = applicationContext.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager?
connMgr?: return false
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    val network: Network = connMgr.activeNetwork ?: return false
    val capabilities = connMgr.getNetworkCapabilities(network)
    return capabilities != null && capabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)
} else {
    val networkInfo = connMgr.activeNetworkInfo ?: return false
    return networkInfo.isConnected && networkInfo.type == ConnectivityManager.TYPE_WIFI
}

Java:

ConnectivityManager connMgr = (ConnectivityManager) getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
if (connMgr == null) {
    return false;
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {

Here is a Swift way to get screen sizes, this also takes current interface orientation into account:

var screenWidth: CGFloat {
    if UIInterfaceOrientationIsPortrait(screenOrientation) {
        return UIScreen.mainScreen().bounds.size.width
    } else {
        return UIScreen.mainScreen().bounds.size.height
    }
}
var screenHeight: CGFloat {
    if UIInterfaceOrientationIsPortrait(screenOrientation) {
        return UIScreen.mainScreen().bounds.size.height
    } else {
        return UIScreen.mainScreen().bounds.size.width
    }
}
var screenOrientation: UIInterfaceOrientation {
    return UIApplication.sharedApplication().statusBarOrientation
}

These are included as a standard function in:

https://github.com/goktugyil/EZSwiftExtensions

SET foreign_key_checks = 0;
TRUNCATE dataflow_batch_export;
TRUNCATE dataflow_batch_import;
TRUNCATE log_customer;
TRUNCATE log_quote;
TRUNCATE log_summary;
TRUNCATE log_summary_type;
TRUNCATE log_url;
TRUNCATE log_url_info;
TRUNCATE log_visitor;
TRUNCATE log_visitor_info;
TRUNCATE log_visitor_online;
TRUNCATE report_viewed_product_index;
TRUNCATE report_compared_product_index;
TRUNCATE report_event;
TRUNCATE index_event;
SET foreign_key_checks = 1;

Versions of IE before IE9 don't have an .indexOf() function for Array, to define the exact spec version, run this before trying to use it:

if (!Array.prototype.indexOf)
{
  Array.prototype.indexOf = function(elt /*, from*/)
  {
    var len = this.length >>> 0;

    var from = Number(arguments[1]) || 0;
    from = (from < 0)
         ? Math.ceil(from)
         : Math.floor(from);
    if (from < 0)
      from += len;

    for (; from < len; from++)
    {
      if (from in this &&
          this[from] === elt)
        return from;
    }
    return -1;
  };
}

This is the version from MDN, used in Firefox/SpiderMonkey. In other cases such as IE, it'll add .indexOf() in the case it's missing... basically IE8 or below at this point.

(I know this is old but I wanted to post this for people like me who stumble upon it in the future) I personally just use this python code to decode base64 strings:

print open("FILE-WITH-STRING", "rb").read().decode("base64")

So you can run it in a bash script like this:

python -c 'print open("FILE-WITH-STRING", "rb").read().decode("base64")' > outputfile
file -i outputfile

twneale has also pointed out an even simpler solution: base64 -d So you can use it like this:

cat "FILE WITH STRING" | base64 -d > OUTPUTFILE
#Or You Can Do This
echo "STRING" | base64 -d > OUTPUTFILE

That will save the decoded string to outputfile and then attempt to identify file-type using either the file tool or you can try TrID. The following command will decode the string into a file and then use TrID to automatically identify the file's type and add the extension.

echo "STRING" | base64 -d > OUTPUTFILE; trid -ce OUTPUTFILE

//just copy this code to your main activity.

 if ( ContextCompat.checkSelfPermission(MainActivity.this, android.Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED ){
            if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this, android.Manifest.permission.READ_EXTERNAL_STORAGE)){

            }else {
                ActivityCompat.requestPermissions(MainActivity.this,new String[]{android.Manifest.permission.READ_EXTERNAL_STORAGE},1);
            }
        }else {
        }

Enums are classes and should follow the conventions for classes. Instances of an enum are constants and should follow the conventions for constants. So

enum Fruit {APPLE, ORANGE, BANANA, PEAR};

There is no reason for writing FruitEnum any more than FruitClass. You are just wasting four (or five) characters that add no information.

Java itself recommends this approach and it is used in their examples.

It looks like Mongo v1.9+ has support for the compact in place!

> db.runCommand( { compact : 'mycollectionname' } )

See the docs here: http://docs.mongodb.org/manual/reference/command/compact/

"Unlike repairDatabase, the compact command does not require double disk space to do its work. It does require a small amount of additional space while working. Additionally, compact is faster."

With my T7300 2.0GHz and Kingston V100 64gb SSD the results are

Bitlocker off ? on

Sequential read 243 MB/s ? 140 MB/s

Sequential write 74.5 MB/s ? 51 MB/s

Random read 176 MB/s ? 100 MB/s

Random write, and the 4KB speeds are almost identical.

Clearly the processor is the bottleneck in this case. In real life usage however boot time is about the same, cold launch of Opera 11.5 with 79 tabs remained the same 4 seconds all tabs loaded from cache.

A small build in VS2010 took 2 seconds in both situations. Larger build took 2 seconds vs 5 from before. These are ballpark because I'm looking at my watch hand.

I guess it all depends on the combination of processor, ram, and ssd vs hdd. In my case the processor has no hardware AES so compilation is worst case scenario, needing cycles for both assembly and crypto.

A newer system with Sandy Bridge would probably make better use of a Bitlocker enabled SDD in a development environment.

Personally I'm keeping Bitlocker enabled despite the performance hit because I travel often. It took less than an hour to toggle Bitlocker on/off so maybe you could just turn it on when you are traveling then disable it afterwards.

Thinkpad X61, Windows 7 SP1

Okay... so I could never get my PENDO pad to show up.. until I encountered this..

process android.process.acore has stopped..

Yeah.. nothing to do with this issue right? Ah ah but it lead me to MOBILEGO. It's a desk application that lets you admin your device.. Guess how.. by connecting via USB. Yep and it does.. It installed everything on my windows box, and now Eclipse has no problem seeing my PENDO.

copied from: https://android.stackexchange.com/questions/12962/flush-clear-dns-cache

Addresses are cached for 600 seconds (10 minutes) by default. Failed lookups are cached for 10 seconds. From everything I've seen, there's nothing built in to flush the cache. This is apparently a reported bug http://code.google.com/p/android/issues/detail?id=7904 in Android because of the way it stores DNS cache. Clearing the browser cache doesn't touch the DNS, the "hard reset" clears it.

One of #a or #b needs to be not position:absolute, so that #box will grow to accommodate it.

So you can stop #a from being position:absolute, and still position #b over the top of it, like this:

 #box {_x000D_
        background-color: #000;_x000D_
        position: relative;     _x000D_
        padding: 10px;_x000D_
        width: 220px;_x000D_
    }_x000D_
    _x000D_
    .a {_x000D_
        width: 210px;_x000D_
        background-color: #fff;_x000D_
        padding: 5px;_x000D_
    }_x000D_
    _x000D_
    .b {_x000D_
        width: 100px; /* So you can see the other one */_x000D_
        position: absolute;_x000D_
        top: 10px; left: 10px;_x000D_
        background-color: red;_x000D_
        padding: 5px;_x000D_
    }_x000D_
    _x000D_
    #after {_x000D_
        background-color: yellow;_x000D_
        padding: 10px;_x000D_
        width: 220px;_x000D_
    }

    <div id="box">_x000D_
        <div class="a">Lorem</div>_x000D_
        <div class="b">Lorem</div>_x000D_
    </div>_x000D_
    <div id="after">Hello world</div>

(Note that I've made the widths different, so you can see one behind the other.)

Edit after Justine's comment: Then your only option is to specify the height of #box. This:

#box {
    /* ... */
    height: 30px;
}

works perfectly, assuming the heights of a and b are fixed. Note that you'll need to put IE into standards mode by adding a doctype at the top of your HTML

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
          "http://www.w3.org/TR/html4/strict.dtd">

before that works properly.

FWIW, this BASH script will take a PEM- or DER-format X.509 certificate or OpenSSL public key file (also PEM format) as the first argument and disgorge an OpenSSH RSA public key. This expands upon @mkalkov's answer above. Requirements are cat, grep, tr, dd, xxd, sed, xargs, file, uuidgen, base64, openssl (1.0+), and of course bash. All except openssl (contains base64) are pretty much guaranteed to be part of the base install on any modern Linux system, except maybe xxd (which Fedora shows in the vim-common package). If anyone wants to clean it up and make it nicer, caveat lector.

#!/bin/bash
#
# Extract a valid SSH format public key from an X509 public certificate.
#

# Variables:
pubFile=$1
fileType="no"
pkEightTypeFile="$pubFile"
tmpFile="/tmp/`uuidgen`-pkEightTypeFile.pk8"

# See if a file was passed:
[ ! -f "$pubFile" ] && echo "Error, bad or no input file $pubFile." && exit 1

# If it is a PEM format X.509 public cert, set $fileType appropriately:
pemCertType="X$(file $pubFile | grep 'PEM certificate')"
[ "$pemCertType" != "X" ] && fileType="PEM"

# If it is an OpenSSL PEM-format PKCS#8-style public key, set $fileType appropriately:
pkEightType="X$(grep -e '-BEGIN PUBLIC KEY-' $pubFile)"
[ "$pkEightType" != "X" ] && fileType="PKCS"

# If this is a file we can't recognise, try to decode a (binary) DER-format X.509 cert:
if [ "$fileType" = "no" ]; then
        openssl x509 -in $pubFile -inform DER -noout
        derResult=$(echo $?)
        [ "$derResult" = "0" ] && fileType="DER"
fi

# Exit if not detected as a file we can use:
[ "$fileType" = "no" ] && echo "Error, input file not of type X.509 public certificate or OpenSSL PKCS#8-style public key (not encrypted)." && exit 1

# Convert the X.509 public cert to an OpenSSL PEM-format PKCS#8-style public key:
if [ "$fileType" = "PEM" -o "$fileType" = "DER" ]; then
        openssl x509 -in $pubFile -inform $fileType -noout -pubkey > $tmpFile
        pkEightTypeFile="$tmpFile"
fi

# Build the string:
# Front matter:
frontString="$(echo -en 'ssh-rsa ')"

# Encoded modulus and exponent, with appropriate pointers:
encodedModulus="$(cat $pkEightTypeFile | grep -v -e "----" | tr -d '\n' | base64 -d | dd bs=1 skip=32 count=257 status=none | xxd -p -c257 | sed s/^/00000007\ 7373682d727361\ 00000003\ 010001\ 00000101\ / | xxd -p -r | base64 -w0 )"

# Add a comment string based on the filename, just to be nice:
commentString=" $(echo $pubFile | xargs basename | sed -e 's/\.crt\|\.cer\|\.pem\|\.pk8\|\.der//')"

# Give the user a string:
echo $frontString $encodedModulus $commentString

# cleanup:
rm -f $tmpFile

In some contexts, you can leverage margin settings to effectively specify "100% width minus N pixels". See the accepted answer to this question.

2 GB by default. If the application is large address space aware (linked with /LARGEADDRESSAWARE), it gets 4 GB (not 3 GB, see http://msdn.microsoft.com/en-us/library/aa366778.aspx)

They're still limited to 2 GB since many application depends on the top bit of pointers to be zero.

I read that you have a c# background. So a good starting point might be a mixin implementation for .NET.

You might want to check out the codeplex project at http://remix.codeplex.com/

The following shows an example of a shared class library shared.[h,cpp] and a main.cpp module using the library. It's a very simple example and the makefile could be made much better. But it works and may help you:

shared.h defines the class:

class myclass {
   int myx;

  public:

    myclass() { myx=0; }
    void setx(int newx);
    int  getx();
};

shared.cpp defines the getx/setx functions:

#include "shared.h"

void myclass::setx(int newx) { myx = newx; }
int  myclass::getx() { return myx; }

main.cpp uses the class,

#include <iostream>
#include "shared.h"

using namespace std;

int main(int argc, char *argv[])
{
  myclass m;

  cout << m.getx() << endl;
  m.setx(10);
  cout << m.getx() << endl;
}

and the makefile that generates libshared.so and links main with the shared library:

main: libshared.so main.o
    $(CXX) -o main  main.o -L. -lshared

libshared.so: shared.cpp
    $(CXX) -fPIC -c shared.cpp -o shared.o
    $(CXX) -shared  -Wl,-soname,libshared.so -o libshared.so shared.o

clean:
    $rm *.o *.so

To actual run 'main' and link with libshared.so you will probably need to specify the load path (or put it in /usr/local/lib or similar).

The following specifies the current directory as the search path for libraries and runs main (bash syntax):

export LD_LIBRARY_PATH=.
./main

To see that the program is linked with libshared.so you can try ldd:

LD_LIBRARY_PATH=. ldd main

Prints on my machine:

  ~/prj/test/shared$ LD_LIBRARY_PATH=. ldd main
    linux-gate.so.1 =>  (0xb7f88000)
    libshared.so => ./libshared.so (0xb7f85000)
    libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb7e74000)
    libm.so.6 => /lib/libm.so.6 (0xb7e4e000)
    libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0xb7e41000)
    libc.so.6 => /lib/libc.so.6 (0xb7cfa000)
    /lib/ld-linux.so.2 (0xb7f89000)

A more or less detailed description, why NetBeans if slow so often can be found in the article:

Boost your NetBeans performance

First. check what NetBeans is actually doing on your disk. On a Mac you can issue this command:

  sudo fs_usage | grep /path/to/workspace

In my special case I got a directory which didn't exist any longer, but NetBeans tries to access the folder all the time:

  14:08:05 getattrlist /path/to/workspaces/pii 0.000011 java

Repeated many, many, many times. If you have a similar problem, fix it by deleting your NetBeans cache folder here:

   ~/.netbeans/6.8/var/cache

If your NetBeans.app is still making a lot of disk I/O. Check if it's accessing the subverison folders and svncache.

I had to disable the subversion features with config file:

  ~/.netbeans/VERSION/config/Preferences/org/netbeans/modules/versioning.properties 

add a line:

  unversionedFolders=FULL_PATH_TO_PROJECT_FOLDER  

SOURCE: Netbeans forums

IMHO it's mainly related to a lot of disk I/O caused by missing files or folders and svncache.

net use f: \\\VFServer"\HQ Publications" /persistent:yes

Note that the first quotation mark goes before the leading \ and the second goes after the end of the folder name.

You could use the Fisher-Yates Shuffle (code adapted from this site):

function shuffle(array) {
    let counter = array.length;

    // While there are elements in the array
    while (counter > 0) {
        // Pick a random index
        let index = Math.floor(Math.random() * counter);

        // Decrease counter by 1
        counter--;

        // And swap the last element with it
        let temp = array[counter];
        array[counter] = array[index];
        array[index] = temp;
    }

    return array;
}

The easiest way is to add the project as a Maven project directly. To do this, in the project explorer on the left, right-click on the POM file for the project, towards the bottom of the context menu, you will see an option called 'Add as Maven Project', click it. This will automatically convert the project to a Maven project

I've stumbled upon the same problem. Program was running great from Eclipse via "Run" button, but NOT from runnable JAR which I'd exported before. My solution was:

1) Move Main class to default package

2) Set other path for Eclipse, and other while running from the JAR file (paste this into Main.java)

public static final String sourcePath = isProgramRunnedFromJar() ? "src/" : "";
public static boolean isProgramRunnedFromJar() {
    File x = getCurrentJarFileLocation();
    if(x.getAbsolutePath().contains("target"+File.separator+"classes")){
        return false;
    } else {
        return true;
    }
}
public static File getCurrentJarFileLocation() {
        try {
            return new File(Main.class.getProtectionDomain().getCodeSource().getLocation().toURI().getPath());
        } catch(URISyntaxException e){
            e.printStackTrace();
            return null;
        }
}

And after that in start method you have to load files like this:

FXMLLoader loader = new FXMLLoader(getClass().getResource(sourcePath +"MainScene.fxml"));

It works for me in Eclipse Mars with e(fx)clipse plugin.

I stumbled on this post while trying to change the display format for dates in sql-developer. Just wanted to add to this what I found out:

• To Change the default display format, I would use the steps provided by ousoo i.e Tools > Preferences > ...

• But a lot of times, I just want to retain the DEFAULT_FORMAT while modifying the format only during a bunch of related queries. That's when I would change the format of the session with the following:

  alter SESSION set NLS_DATE_FORMAT = 'my_required_date_format'

Eg:

   alter SESSION set NLS_DATE_FORMAT = 'DD-MM-YYYY HH24:MI:SS' 

you can use the <text> tag for both cshtml code with javascript

I suddenly had the same problem, after no noteworthy changes.

I solved it by deleting the app/build directory and let gradle build the whole project new.

Just Adding Another Method-

Replacing Multiple Spaces with Single Space WITHOUT Using REPLACE in SQL Server-

DECLARE @TestTable AS TABLE(input VARCHAR(MAX));

INSERT INTO @TestTable VALUES
('HAPPY         NEWYEAR     2020'),
('WELCOME       ALL     !');

SELECT
    CAST('<r><![CDATA[' + input + ']]></r>' AS XML).value('(/r/text())[1] cast as xs:token?','VARCHAR(MAX)')
    AS Expected_Result
FROM @TestTable;

--OUTPUT
/*
Expected_Result
HAPPY NEWYEAR 2020
WELCOME ALL !
*/

const check = vendors.find((item)=>item.Name==='Magenic')

console.log(check)

Try this code.

If the item or element is present then the output will show you that element. If it is not present then the output will be 'undefined'.

So the key parts are to grab the header ( col_names = s.row(0) ) and when iterating through the rows, to skip the first row which isn't needed for row in range(1, s.nrows) - done by using range from 1 onwards (not the implicit 0). You then use zip to step through the rows holding 'name' as the header of the column.

from xlrd import open_workbook

wb = open_workbook('Book2.xls')
values = []
for s in wb.sheets():
    #print 'Sheet:',s.name
    for row in range(1, s.nrows):
        col_names = s.row(0)
        col_value = []
        for name, col in zip(col_names, range(s.ncols)):
            value  = (s.cell(row,col).value)
            try : value = str(int(value))
            except : pass
            col_value.append((name.value, value))
        values.append(col_value)
print values

You should put the print function in your view-details.php file and call it once the file is loaded, by either using

<body onload="window.print()"> 

or

$(document).ready(function () { 
  window.print(); 
});

OSX 10.15.0 Catalina (released November 2019) changed the default shell to zsh.

The default shell was previously bash.

The installation command given on the nvm GitHub page needs to be tweaked to include "zsh" at the end.

curl https://raw.githubusercontent.com/creationix/nvm/master/install.sh | zsh

Note: you might need to ensure the .rc file for zsh is present beforehand:

touch ~/.zsrhrc

I checked all the solutions on this post and the post that @kenorb referenced above, and I did not find any solution that worked for me.

I am using Git 1.9.5 Preview on Windows 7 with the following configuration: - Run Git from the Windows Command Prompt - Checkout Windows-style, commit Unix-style line endings

I used the 'Git Bash' console for everything... And all was well until I tried to install the SSH keys. GitHub's documentation says to do the following (don't run these commands until you finish reading the post):

Ensure ssh-agent is enabled:

If you are using Git Bash, turn on ssh-agent:

# start the ssh-agent in the background
ssh-agent -s
# Agent pid 59566

If you are using another terminal prompt, such as msysgit, turn on ssh-agent:

# start the ssh-agent in the background
eval $(ssh-agent -s)
# Agent pid 59566

Now of course I missed the fact that you were supposed to do one or the other. So, I ran these commands multiple times because the later ssh-add command was failing, so I returned to this step, and continued to retry over and over.

This results in 1 Windows 'ssh-agent' process being created every single time you run these commands (notice the new PID every time you enter those commands?)

So, Ctrl+Alt+Del and hit End Process to stop each 'ssh-agent.exe' process.

Now that all the messed up stuff from the failed attempts is cleaned up, I will tell you how to get it working...

In 'Git Bash':

Start the 'ssh-agent.exe' process

eval $(ssh-agent -s)

And install the SSH keys

ssh-add "C:\Users\MyName\.ssh\id_rsa"

* Adjust the path above with your username, and make sure that the location of the* /.ssh directory is in the correct place. I think you choose this location during the Git installation? Maybe not...

The part I was doing wrong before I figured this out was I was not using quotes around the 'ssh-add' location. The above is how it needs to be entered on Windows.

There's a tiny open-source component to sync/communicate between tabs/windows of the same origin (disclaimer - I'm one of the contributors!) based around localStorage.

TabUtils.BroadcastMessageToAllTabs("eventName", eventDataString);

TabUtils.OnBroadcastMessage("eventName", function (eventDataString) {
    DoSomething();
});

TabUtils.CallOnce("lockname", function () {
    alert("I run only once across multiple tabs");
});

https://github.com/jitbit/TabUtils

P.S. I took the liberty to recommend it here since most of the "lock/mutex/sync" components fail on websocket connections when events happen almost simultaneously

To supplement what everyone else has said above, your js file is being read on the client side when you have a path to it in your HTML file. At least that was the problem for me. I had it as a script in my tag in my index.html Hope this helps!

For case-insensitive string search, use index (or rindex) in combination with fc. This example expands on the answer by Eugene Yarmash:

use feature qw( fc ); 
my $str = "Abc"; 
my $substr = "aB"; 

print "found" if index( fc $str, fc $substr ) != -1;
# Prints: found

print "found" if rindex( fc $str, fc $substr ) != -1;
# Prints: found

$str = "Abc";
$substr = "bA";

print "found" if index( fc $str, fc $substr ) != -1;
# Prints nothing

print "found" if rindex( fc $str, fc $substr ) != -1;
# Prints nothing

Both index and rindex return -1 if the substring is not found.
And fc returns a casefolded version of its string argument, and should be used here instead of the (more familiar) uc or lc. Remember to enable this function, for example with use feature qw( fc );.

it is now simply:

let serialQueue = DispatchQueue(label: "my serial queue")

the default is serial, to get concurrent, you use the optional attributes argument .concurrent

Try to cast it as a DATE

SELECT CAST(orders.date_purchased AS DATE) AS DATE_PURCHASED

You can use this:

response.sendRedirect(String.format("%s%s", request.getContextPath(), "/views/equipment/createEquipment.jsp"));

The last part is your path in your web-app

I think what you are looking for is to keep the background image fixed and just move the content on scroll. For that you have to simply use the following css property :

background-attachment: fixed;

I disagree with this kind of path

GET /companies/{companyId}/departments

If you want to get departments, I think it's better to use a /departments resource

GET /departments?companyId=123

I suppose you have a companies table and a departments table then classes to map them in the programming language you use. I also assume that departments could be attached to other entities than companies, so a /departments resource is straightforward, it's convenient to have resources mapped to tables and also you don't need as many endpoints since you can reuse

GET /departments?companyId=123

for any kind of search, for instance

GET /departments?name=xxx
GET /departments?companyId=123&name=xxx
etc.

If you want to create a department, the

POST /departments

resource should be used and the request body should contain the company ID (if the department can be linked to only one company).

matches method performs matching of full line, i.e. it is equivalent to find() with '^abc$'. So, just use Pattern.compile("[a-zA-Z]").matcher(str).find() instead. Then fix your regex. As @user unknown mentioned your regex actually matches only one character. You probably should say [a-zA-Z]+

Consider using subtree instead of submodules, it will make your repo users life much easier. You may find more detailed guide in Pro Git book.

$date = "Mar 03, 2011";
$date = strtotime($date);
$date = strtotime("+7 day", $date);
echo date('M d, Y', $date);

To send to both remote with one command, you can create a alias for it:

git config alias.pushall '!git push origin devel && git push github devel'

With this, when you use the command git pushall, it will update both repositories.

Since it wasn't mentioned in the other answers, I'd like to add that if you want case SearchAuthors to be executed right after the first case, just like omitting the break in some other programming languages where that is allowed, you can simply use goto.

switch (searchType)
{
    case "SearchBooks":
    Selenium.Type("//*[@id='SearchBooks_TextInput']", searchText);
    Selenium.Click("//*[@id='SearchBooks_SearchBtn']");
    goto case "SearchAuthors";

    case "SearchAuthors":
    Selenium.Type("//*[@id='SearchAuthors_TextInput']", searchText);
    Selenium.Click("//*[@id='SearchAuthors_SearchBtn']");
    break;
}

One (dirty) way to do it is to use tryCatch with an empty function for error handling. For example, the following code raises an error and breaks the loop :

for (i in 1:10) {
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
Erreur : Urgh, the iphone is in the blender !

But you can wrap your instructions into a tryCatch with an error handling function that does nothing, for example :

for (i in 1:10) {
  tryCatch({
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
  }, error=function(e){})
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
[1] 8
[1] 9
[1] 10

But I think you should at least print the error message to know if something bad happened while letting your code continue to run :

for (i in 1:10) {
  tryCatch({
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
  }, error=function(e){cat("ERROR :",conditionMessage(e), "\n")})
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
ERROR : Urgh, the iphone is in the blender ! 
[1] 8
[1] 9
[1] 10

EDIT : So to apply tryCatch in your case would be something like :

for (v in 2:180){
    tryCatch({
        mypath=file.path("C:", "file1", (paste("graph",names(mydata[columnname]), ".pdf", sep="-")))
        pdf(file=mypath)
        mytitle = paste("anything")
        myplotfunction(mydata[,columnnumber]) ## this function is defined previously in the program
        dev.off()
    }, error=function(e){cat("ERROR :",conditionMessage(e), "\n")})
}

For comaparing a list or set we can use Arrays.equals(object[], object[]). It will check for the values only. To get the Object[] we can use Collection.toArray() method.

specify your marks:

List<Double> marks = new ArrayList<Double>();

This is called generics.

I'm using Compact Framework 3.5, and not has a "char.Parse" method. I think is not bad to use the Convert class. (See CLR via C#, Jeffrey Richter)

char letterA = Convert.ToChar(65);
Console.WriteLine(letterA);
letterA = '?';
ushort valueA = Convert.ToUInt16(letterA);
Console.WriteLine(valueA);
char japaneseA = Convert.ToChar(valueA);
Console.WriteLine(japaneseA);

Works with ASCII char or Unicode char

 api.com/users?id=id1,id2,id3,id4,id5
 api.com/users?ids[]=id1&ids[]=id2&ids[]=id3&ids[]=id4&ids[]=id5

IMO, above calls does not looks RESTful, however these are quick and efficient workaround (y). But length of the URL is limited by webserver, eg tomcat.

RESTful attempt:

POST http://example.com/api/batchtask

   [
    {
      method : "GET",
      headers : [..],
      url : "/users/id1"
    },
    {
      method : "GET",
      headers : [..],
      url : "/users/id2"
    }
   ]

Server will reply URI of newly created batchtask resource.

201 Created
Location: "http://example.com/api/batchtask/1254"

Now client can fetch batch response or task progress by polling

GET http://example.com/api/batchtask/1254

This is how others attempted to solve this issue:

Use https://prestodb.io/docs/current/connector/kafka-tutorial.html

A super SQL engine, provided by Facebook, that connects on several data sources (Cassandra, Kafka, JMX, Redis ...).

PrestoDB is running as a server with optional workers (there is a standalone mode without extra workers), then you use a small executable JAR (called presto CLI) to make queries.

Once you have configured well the Presto server , you can use traditionnal SQL:

SELECT count(*) FROM TOPIC_NAME;

<meta http-equiv="refresh" content="10" >

This can work. Try it..!! :-)

That functionality is already built into Notepad++. From the "Edit" menu, select "EOL Conversion" -> "UNIX/OSX Format".

screenshot of the option for even quicker finding (or different language versions)

You can also set the default EOL in notepad++ via "Settings" -> "Preferences" -> "New Document/Default Directory" then select "Unix/OSX" under the Format box.

Your code doesn't work for binary files because they can't be cast to strings in the data event handler. If you need to manipulate binary files you'll need to use a buffer. Sorry, I do not have an example of using a buffer because in my case I needed to manipulate HTML files. I just check the content type and then for text/html files update them as needed:

app.get('/*', function(clientRequest, clientResponse) {
  var options = { 
    hostname: 'google.com',
    port: 80, 
    path: clientRequest.url,
    method: 'GET'
  };  

  var googleRequest = http.request(options, function(googleResponse) { 
    var body = ''; 

    if (String(googleResponse.headers['content-type']).indexOf('text/html') !== -1) {
      googleResponse.on('data', function(chunk) {
        body += chunk;
      }); 

      googleResponse.on('end', function() {
        // Make changes to HTML files when they're done being read.
        body = body.replace(/google.com/gi, host + ':' + port);
        body = body.replace(
          /<\/body>/, 
          '<script src="http://localhost:3000/new-script.js" type="text/javascript"></script></body>'
        );

        clientResponse.writeHead(googleResponse.statusCode, googleResponse.headers);
        clientResponse.end(body);
      }); 
    }   
    else {
      googleResponse.pipe(clientResponse, {
        end: true
      }); 
    }   
  }); 

  googleRequest.end();
});    

the same problem also happened to me when i training my classification model. the reason caused this problem is as what the warning message said "in labels with no predicated samples", it will caused the zero-division when compute f1-score. I found another solution when i read sklearn.metrics.f1_score doc, there is a note as follows:

When true positive + false positive == 0, precision is undefined; When true positive + false negative == 0, recall is undefined. In such cases, by default the metric will be set to 0, as will f-score, and UndefinedMetricWarning will be raised. This behavior can be modified with zero_division

the zero_division default value is "warn", you could set it to 0 or 1 to avoid UndefinedMetricWarning. it works for me ;) oh wait, there is another problem when i using zero_division, my sklearn report that no such keyword argument by using scikit-learn 0.21.3. Just update your sklearn to the latest version by running pip install scikit-learn -U

You can use PowerShell to generate a self-signed certificate with the new-selfsignedcertificate cmdlet:

New-SelfSignedCertificate -DnsName "localhost" -CertStoreLocation "cert:\LocalMachine\My"

Note: makecert.exe is deprecated.

Cmdlet Reference: https://technet.microsoft.com/itpro/powershell/windows/pkiclient/new-selfsignedcertificate

You need $event.currentTarget instead of $event.target.

Try This and you can adjust date formate accordingly:

var today = new Date();
    var dd = today.getDate();
    var mm = today.getMonth() + 1;
    var yyyy = today.getFullYear();
    if (dd < 10) {
        dd = '0' + dd;
    }
    if (mm < 10) {
        mm = '0' + mm;
    }
 var myDate= dd + '-' + mm + '-' + yyyy;

While trying to connect to a SiteGround server via Putty I had the same problem. Their instructions are pretty thorough, and must work for some people, but didn't work for me.

They recommend running pageant.exe, which runs in the background. You register your key(s) with Pageant, and it's supposed to let Putty know about the keys when it tries to connect.

In a couple of places I found suggestions to specify the key directly in the Putty session definition: Putty Configuration > Connection > SSH > Auth > "Private key file for authentication", then browse to your key file in .ppk format.

Doing this without running Pageant resolved the problem for me.

Are you meaning?

data2 <- data1[good,]

With

data1[good]

you're selecting columns in a wrong way (using a logical vector of complete rows).

Consider that parameter pollutant is not used; is it a column name that you want to extract? if so it should be something like

data2 <- data1[good, pollutant]

Furthermore consider that you have to rbind the data.frames inside the for loop, otherwise you get only the last data.frame (its completed.cases)

And last but not least, i'd prefer generating filenames eg with

id <- 1:322
paste0( directory, "/", gsub(" ", "0", sprintf("%3d",id)), ".csv")

A little modified chunk of ?sprintf

The string fmt (in our case "%3d") contains normal characters, which are passed through to the output string, and also conversion specifications which operate on the arguments provided through .... The allowed conversion specifications start with a % and end with one of the letters in the set aAdifeEgGosxX%. These letters denote the following types:

• d: integer

Eg a more general example

    sprintf("I am %10d years old", 25)
[1] "I am         25 years old"
          ^^^^^^^^^^
          |        |
          1       10

The function itself is valid matlab-code. The problem must be something else.
Try calling the function from within the directory it is located or add that directory to your searchpath using addpath('pathname').

That is very odd.

I went through ItemNotFoundException's base classes and tested the following multiple catches to see what would catch it:

try {
  remove-item C:\nonexistent\file.txt -erroraction stop
}
catch [System.Management.Automation.ItemNotFoundException] {
  write-host 'ItemNotFound'
}
catch [System.Management.Automation.SessionStateException] {
  write-host 'SessionState'
}
catch [System.Management.Automation.RuntimeException] {
  write-host 'RuntimeException'
}
catch [System.SystemException] {
  write-host 'SystemException'
}
catch [System.Exception] {
  write-host 'Exception'
}
catch {
  write-host 'well, darn'
}

As it turns out, the output was 'RuntimeException'. I also tried it with a different exception CommandNotFoundException:

try {
  do-nonexistent-command
}
catch [System.Management.Automation.CommandNotFoundException] {
  write-host 'CommandNotFoundException'
}
catch {
  write-host 'well, darn'
}

That output 'CommandNotFoundException' correctly.

I vaguely remember reading elsewhere (though I couldn't find it again) of problems with this. In such cases where exception filtering didn't work correctly, they would catch the closest Type they could and then use a switch. The following just catches Exception instead of RuntimeException, but is the switch equivalent of my first example that checks all base types of ItemNotFoundException:

try {
  Remove-Item C:\nonexistent\file.txt -ErrorAction Stop
}
catch [System.Exception] {
  switch($_.Exception.GetType().FullName) {
    'System.Management.Automation.ItemNotFoundException' {
      write-host 'ItemNotFound'
    }
    'System.Management.Automation.SessionStateException' {
      write-host 'SessionState'
    }
    'System.Management.Automation.RuntimeException' {
      write-host 'RuntimeException'
    }
    'System.SystemException' {
      write-host 'SystemException'
    }
    'System.Exception' {
      write-host 'Exception'
    }
    default {'well, darn'}
  }
}

This writes 'ItemNotFound', as it should.

I believe you're looking for HttpServerUtility.UrlEncode.

System.Web.HttpUtility.UrlEncode(string url)

Textarea resize control is available via the CSS3 resize property:

textarea { resize: both; } /* none|horizontal|vertical|both */
textarea.resize-vertical{ resize: vertical; }
textarea.resize-none { resize: none; }

Allowable values self-explanatory: none (disables textarea resizing), both, vertical and horizontal.

Notice that in Chrome, Firefox and Safari the default is both.

If you want to constrain the width and height of the textarea element, that's not a problem: these browsers also respect max-height, max-width, min-height, and min-width CSS properties to provide resizing within certain proportions.

Code example:

#textarea-wrapper {_x000D_
  padding: 10px;_x000D_
  background-color: #f4f4f4;_x000D_
  width: 300px;_x000D_
}_x000D_
_x000D_
#textarea-wrapper textarea {_x000D_
  min-height:50px;_x000D_
  max-height:120px;_x000D_
  width: 290px;_x000D_
}_x000D_
_x000D_
#textarea-wrapper textarea.vertical { _x000D_
  resize: vertical;_x000D_
}

<div id="textarea-wrapper">_x000D_
  <label for="resize-default">Textarea (default):</label>_x000D_
  <textarea name="resize-default" id="resize-default"></textarea>_x000D_
  _x000D_
  <label for="resize-vertical">Textarea (vertical):</label>_x000D_
  <textarea name="resize-vertical" id="resize-vertical" class="vertical">Notice this allows only vertical resize!</textarea>_x000D_
</div>

I know this question is a little old, but it still comes up first in a lot of Google searches. I wanted to add in a solution that doesn't involve editing the style sheet (in my case, I didn't have access):

<ol type="A">_x000D_
  <li style="font-weight: bold;">_x000D_
    <p><span style="font-weight: normal;">Text</span></p>_x000D_
  </li>_x000D_
  <li style="font-weight: bold;">_x000D_
    <p><span style="font-weight: normal;">More text</span></p>_x000D_
  </li>_x000D_
</ol>

In your web.php (routes):

add:

Route::get('logout', '\App\Http\Controllers\Auth\LoginController@logout');

In your LoginController.php

add:

public function logout(Request $request) {
  Auth::logout();
  return redirect('/login');
}

Also, in the top of LoginController.php, after namespace

add:

use Auth;

Now, you are able to logout using yourdomain.com/logout URL or if you have created logout button, add href to /logout

Inside OnCreate, add:

 webview.getSettings().setSupportZoom(true);
 webview.getSettings().setBuiltInZoomControls(true);
 webview.getSettings().setDisplayZoomControls(false);

Inside the html document, add:

<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=2, user-scalable=yes">
</head>
</html>

Inside javascript, omit:

//event.preventDefault ? event.preventDefault() : (event.returnValue = false);

A few things happening here:

1. I assume you required fs/http, and set the dir variable :)
2. google.com redirects to www.google.com, so you're saving the redirect response's body, not the image
3. the response is streamed. that means the 'data' event fires many times, not once. you have to save and join all the chunks together to get the full response body
4. since you're getting binary data, you have to set the encoding accordingly on response and writeFile (default is utf8)

This should work:

var http = require('http')
  , fs = require('fs')
  , options

options = {
    host: 'www.google.com'
  , port: 80
  , path: '/images/logos/ps_logo2.png'
}

var request = http.get(options, function(res){
    var imagedata = ''
    res.setEncoding('binary')

    res.on('data', function(chunk){
        imagedata += chunk
    })

    res.on('end', function(){
        fs.writeFile('logo.png', imagedata, 'binary', function(err){
            if (err) throw err
            console.log('File saved.')
        })
    })

})

input() by default takes the input in form of strings.

if (0<= vote <=24):

vote takes a string input (suppose 4,5,etc) and becomes uncomparable.

The correct way is: vote = int(input("Enter your message")will convert the input to integer (4 to 4 or 5 to 5 depending on the input)

Here's the very simple way to calculate primes between a given range(1 to limit).

Simple Solution:

    public static void getAllPrimeNumbers(int limit) {

        System.out.println("Printing prime number from 1 to " + limit);

        for(int number=2; number<=limit; number++){
            //***print all prime numbers upto limit***
            if(isPrime(number)){
                System.out.println(number);
            }
        }
    }


    public static boolean isPrime(int num) {
        if (num == 0 || num == 1) {
            return false;
        }
        if (num == 2) { 
            return true;
        }

        for (int i = 2; i <= num / 2; i++) {
            if (num % i == 0) {
                return false;
            }
        }
        return true;
    }

I alse had the same error. Finally, I found that I have some error on my code. I use load balance for two nodejs server, but I just update the code of one server.

I change my mongod server from standalone to replication, but I forget to do the corresponding update for the connection string, so I met this error.

standalone connection string: mongodb://server-1:27017/mydb replication connection string: mongodb://server-1:27017,server-2:27017,server-3:27017/mydb?replicaSet=myReplSet

details here:[mongo doc for connection string]

If you need to check whether the elements of one vector are in another, the best solution is ismember as mentioned in the other answers.

ismember([15 17],primes(20))

However when you are dealing with floating point numbers, or just want to have close matches (+- 1000 is also possible), the best solution I found is the fairly efficient File Exchange Submission: ismemberf

It gives a very practical example:

[tf, loc]=ismember(0.3, 0:0.1:1) % returns false 
[tf, loc]=ismemberf(0.3, 0:0.1:1) % returns true

Though the default tolerance should normally be sufficient, it gives you more flexibility

ismemberf(9.99, 0:10:100) % returns false
ismemberf(9.99, 0:10:100,'tol',0.05) % returns true

From docs

import operator
list(map(operator.add, first,second))

You could use boost::size, which is basically defined this way:

template <typename T, std::size_t N>
std::size_t size(T const (&)[N])
{
    return N;
}

Note that if you want to use the size as a constant expression, you'll either have to use the sizeof a / sizeof a[0] idiom or wait for the next version of the C++ standard.

I just wanted to answer something new for this question - J2V8.

Author Ian Bull says "Rhino and Nashorn are two common JavaScript runtimes, but these did not meet our requirements in a number of areas:

Neither support ‘Primitives‘. All interactions with these platforms require wrapper classes such as Integer, Double or Boolean. Nashorn is not supported on Android. Rhino compiler optimizations are not supported on Android. Neither engines support remote debugging on Android.""

I am sure this can help. Create fileA anywhere in the directory and export all the functions.

export const func1=()=>{
    // do stuff
}
export const func2=()=>{
    // do stuff 
}
export const func3=()=>{
    // do stuff 
}
export const func4=()=>{
    // do stuff 
}
export const func5=()=>{
    // do stuff 
}

Here, in your React component class, you can simply write one import statement.

import React from 'react';
import {func1,func2,func3} from 'path_to_fileA';

class HtmlComponents extends React.Component {
    constructor(props){
        super(props);
        this.rippleClickFunction=this.rippleClickFunction.bind(this);
    }
    rippleClickFunction(){
        //do stuff. 
        // foo==bar
        func1(data);
        func2(data)
    }
   render() {
      return (
         <article>
             <h1>React Components</h1>
             <RippleButton onClick={this.rippleClickFunction}/>
         </article>
      );
   }
}

export default HtmlComponents;

As far as I know there is no mechanism for doing this in JUnit, however you could try subclassing Suite and overriding the run() method with a version that does provide hooks.

You can generate statement like this: DROP TABLE t1, t2, t3, ... and then use prepared statements to execute it:

SET FOREIGN_KEY_CHECKS = 0; 
SET @tables = NULL;
SELECT GROUP_CONCAT('`', table_schema, '`.`', table_name, '`') INTO @tables
  FROM information_schema.tables 
  WHERE table_schema = 'database_name'; -- specify DB name here.

SET @tables = CONCAT('DROP TABLE ', @tables);
PREPARE stmt FROM @tables;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SET FOREIGN_KEY_CHECKS = 1; 

if grep -q SomeString "$File"; then
  Some Actions # SomeString was found
fi

You don't need [[ ]] here. Just run the command directly. Add -q option when you don't need the string displayed when it was found.

The grep command returns 0 or 1 in the exit code depending on the result of search. 0 if something was found; 1 otherwise.

$ echo hello | grep hi ; echo $?
1
$ echo hello | grep he ; echo $?
hello
0
$ echo hello | grep -q he ; echo $?
0

You can specify commands as an condition of if. If the command returns 0 in its exitcode that means that the condition is true; otherwise false.

$ if /bin/true; then echo that is true; fi
that is true
$ if /bin/false; then echo that is true; fi
$

As you can see you run here the programs directly. No additional [] or [[]].

To ensure an enum value exists and then parse it, you can also do the following.

// Fake Day of Week
string strDOWFake = "SuperDay";

// Real Day of Week
string strDOWReal = "Friday";

// Will hold which ever is the real DOW.
DayOfWeek enmDOW;

// See if fake DOW is defined in the DayOfWeek enumeration.
if (Enum.IsDefined(typeof(DayOfWeek), strDOWFake))
{
    // This will never be reached since "SuperDay"
    // doesn't exist in the DayOfWeek enumeration.
    enmDOW = (DayOfWeek)Enum.Parse(typeof(DayOfWeek), strDOWFake);
}
// See if real DOW is defined in the DayOfWeek enumeration.
else if (Enum.IsDefined(typeof(DayOfWeek), strDOWReal))
{
    // This will parse the string into it's corresponding DOW enum object.
    enmDOW = (DayOfWeek)Enum.Parse(typeof(DayOfWeek), strDOWReal);
}

// Can now use the DOW enum object.
Console.Write("Today is " + enmDOW.ToString() + ".");

Use lowercase letters and try again

TL;DR

int *sieve = (int *) malloc(sizeof(int) * length);

has two problems. The cast and that you're using the type instead of variable as argument for sizeof. Instead, do like this:

int *sieve = malloc(sizeof *sieve * length);

Long version

No; you don't cast the result, since:

• It is unnecessary, as void * is automatically and safely promoted to any other pointer type in this case.
• It adds clutter to the code, casts are not very easy to read (especially if the pointer type is long).
• It makes you repeat yourself, which is generally bad.
• It can hide an error if you forgot to include <stdlib.h>. This can cause crashes (or, worse, not cause a crash until way later in some totally different part of the code). Consider what happens if pointers and integers are differently sized; then you're hiding a warning by casting and might lose bits of your returned address. Note: as of C99 implicit functions are gone from C, and this point is no longer relevant since there's no automatic assumption that undeclared functions return int.

As a clarification, note that I said "you don't cast", not "you don't need to cast". In my opinion, it's a failure to include the cast, even if you got it right. There are simply no benefits to doing it, but a bunch of potential risks, and including the cast indicates that you don't know about the risks.

Also note, as commentators point out, that the above talks about straight C, not C++. I very firmly believe in C and C++ as separate languages.

To add further, your code needlessly repeats the type information (int) which can cause errors. It's better to de-reference the pointer being used to store the return value, to "lock" the two together:

int *sieve = malloc(length * sizeof *sieve);

This also moves the length to the front for increased visibility, and drops the redundant parentheses with sizeof; they are only needed when the argument is a type name. Many people seem to not know (or ignore) this, which makes their code more verbose. Remember: sizeof is not a function! :)

While moving length to the front may increase visibility in some rare cases, one should also pay attention that in the general case, it should be better to write the expression as:

int *sieve = malloc(sizeof *sieve * length);

Since keeping the sizeof first, in this case, ensures multiplication is done with at least size_t math.

Compare: malloc(sizeof *sieve * length * width) vs. malloc(length * width * sizeof *sieve) the second may overflow the length * width when width and length are smaller types than size_t.

to get the context inside the Fragment will be possible using getActivity() :

public Database()
{
    this.context = getActivity();
    DBHelper = new DatabaseHelper(this.context);
}

• Be careful, to get the Activity associated with the fragment using getActivity(), you can use it but is not recommended it will cause memory leaks.

I think a better aproach must be getting the Activity from the onAttach() method:

@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);
    context = activity;
}

it's not true the clear() function clear the Arraylist and start from index 0

Turn on debug logging to get a better picture of what is going on.

You can tell if the session cookies are being set by using a browser-side debugger to look at the headers returned in HTTP responses. (There are other ways too.)

One possibility is that SpringSecurity is setting secure session cookies, and your next page requested has an "http" URL instead of an "https" URL. (The browser won't send a secure cookie for an "http" URL.)

Using np.percentile.

q75, q25 = np.percentile(DataFrame, [75,25])
iqr = q75 - q25

Answer from How do you find the IQR in Numpy?

Try this:

var itemsInCart = from o in db.OrderLineItems
                  where o.OrderId == currentOrder.OrderId
                  select o.WishListItem.Price;

return Convert.ToDecimal(itemsInCart.Sum());

I think it's more simple!

If you want to generate a number of random booleans you could use numpy's random module. From the documentation

np.random.randint(2, size=10)

will return 10 random uniform integers in the open interval [0,2). The size keyword specifies the number of values to generate.

if you are using IOS react native platform and want to debugging real android device you can use following code:

adb reverse tcp:8081 tcp:8081
npm start -- --reset-cache
react-native run-android

Run As > Java Application wont show up if the class that you want to run does not contain the main method. Make sure that the class you trying to run has main defined in it.

Alternatively to hobodave's answer

SELECT * FROM table
WHERE YEAR(date_created) = YEAR(CURRENT_DATE - INTERVAL 1 MONTH)
AND MONTH(date_created) = MONTH(CURRENT_DATE - INTERVAL 1 MONTH)

You could achieve the same with EXTRACT, using YEAR_MONTH as unit, thus you wouldn't need the AND, like so:

SELECT * FROM table
WHERE EXTRACT(YEAR_MONTH FROM date_created) = EXTRACT(YEAR_MONTH FROM CURDATE() - INTERVAL
1 MONTH)

/***Your Code***/
public void paintComponent(Graphics g){
/***Your Code***/
    g.setColor(Color.RED);
    g.fillOval(50,50,20,20);
}

g.fillOval(x-axis,y-axis,width,height);

An alternative way to code Brettski's answer, with which I otherwise agree entirely, might be

With New FileSystemObject
    If .FileExists(yourFilePath) Then
        .DeleteFile yourFilepath
    End If
End With

Same effect but fewer (well, none at all) variable declarations.

The FileSystemObject is a really useful tool and well worth getting friendly with. Apart from anything else, for text file writing it can actually sometimes be faster than the legacy alternative, which may surprise a few people. (In my experience at least, YMMV).

As of .NET Core 2.2, TargetMigration seems to be gone:

get-help Update-Database

NAME
    Update-Database

SYNOPSIS
    Updates the database to a specified migration.


SYNTAX
    Update-Database [[-Migration] <String>] [-Context <String>] [-Project <String>] [-StartupProject <String>] [<CommonParameters>]


DESCRIPTION
    Updates the database to a specified migration.


RELATED LINKS
    Script-Migration
    about_EntityFrameworkCore 

REMARKS
    To see the examples, type: "get-help Update-Database -examples".
    For more information, type: "get-help Update-Database -detailed".
    For technical information, type: "get-help Update-Database -full".
    For online help, type: "get-help Update-Database -online"

So this works for me now:

Update-Database -Migration 20180906131107_xxxx_xxxx

As well as (no -Migration switch):

Update-Database 20180906131107_xxxx_xxxx

On an added note, you can no longer cleanly delete migration folders without putting your Model Snapshot out of sync. So if you learn this the hard way and wind up with an empty migration where you know there should be changes, you can run (no switches needed for the last migration):

Remove-migration

It will clean up the mess and put you back where you need to be, even though the last migration folder was deleted manually.

I believe the main (only?) different is inheritance:

class T < S
end

p T.k
=> 23

S.k = 24
p T.k
=> 24

p T.s
=> nil

Class variables are shared by all "class instances" (i.e. subclasses), whereas class instance variables are specific to only that class. But if you never intend to extend your class, the difference is purely academic.

You may also try this,

var arr = $('input[name="myCheckboxes[]"]').map(function(){
  return $(this).val();
}).get();

console.log(arr);

There is a pull request here. But you can simply do train, test = next(iter(StratifiedKFold(...))) and use the train and test indices if you want.

A quick answer:

mvn -fn test

Works with nested project builds.

Just use CSS.

.myclass 
{
    text-transform:capitalize;
}

This doesn't work for me. I've tried this both under Win7 64bit and Vista 32.

I'm using the below commandline to add this capability.

reg add "HKEY_CURRENT_USER\Software\Microsoft\Command Processor" /v AutoRun /t REG_SZ /d "IF x"%COMSPEC%"==x%CMDCMDLINE% (cd /D c:)"

Did you by chance not "trust" the device? This will prevent it from communicating with xcode even if the device is unlocked.

Update here's a support doc from Apple: http://support.apple.com/en-us/HT5868

I just encountered this problem myself and found that Ubuntu 14.04 uses Upstart instead of Systemd, so systemctl commands will not work. This changed in 15.04, so one way around this would be to update your ubuntu install.

If this is not an option for you (it's not for me right now), you need to find the Upstart command that does what you need to do.

For enable, the generic looks to be the following:

update-rc.d <service> enable

Here is the sample controller which connects to MySql database using the mysql package. We mainly make use of MySqlConnection connection object.

 public class HomeController : Controller
{
    public ActionResult Index()
    {
        List<employeemodel> employees = new List<employeemodel>();
        string constr = ConfigurationManager.ConnectionStrings["ConString"].ConnectionString;
        using (MySqlConnection con = new MySqlConnection(constr))
        {
            string query = "SELECT EmployeeId, Name, Country FROM Employees";
            using (MySqlCommand cmd = new MySqlCommand(query))
            {
                cmd.Connection = con;
               con.Open();
                using (MySqlDataReader sdr = cmd.ExecuteReader())
                {
                    while (sdr.Read())
                    {
                        employees.Add(new EmployeeModel
                        {
                            EmployeeId = Convert.ToInt32(sdr["EmployeeId"]),
                            Name = sdr["Name"].ToString(),
                            Country = sdr["Country"].ToString()
                        });
                    }
                }
                con.Close();
            }
        }

        return View(employees);
    }
}

Well, container objects' __str__ methods will use repr on their contents, not str. So you could use __repr__ instead of __str__, seeing as you're using an ID as the result.

Try this

<xs:element name="description" type="xs:string" minOccurs="0" maxOccurs="1" />

if you want 0 or 1 "description" elements, Or

<xs:element name="description" type="xs:string" minOccurs="0" maxOccurs="unbounded" />

if you want 0 to infinity number of "description" elements.

The user can also use Eclipse's keyboard shortcuts: just go on menu Setting ? Preferences ? Keymap and choose Eclipse (or any one you like) from the dropdown menu.

You can do it in this way.

somearray = somearray.map(Number);

var total = somearray.reduce(function(a,b){  return a+b },0)

console.log(total);

In my case, I found (after much hair-pulling) that the "pending" status was caused by the AdBlock extension. The image that I couldn't get to load had the word "ad" in the URL, so AdBlock kept it from loading.

Disabling AdBlock fixes this issue.

Renaming the file so that it doesn't contain "ad" in the URL also fixes it, and is obviously a better solution. Unless it's an advertisement, in which case you should leave it like that. :)

You will certainly be able to do that using WITH clause, or use analytic functions available in Oracle SQL.

With some effort you'd be able to get anything out of them in terms of cycles as in ordinary procedural languages. Both approaches are pretty powerful compared to ordinary SQL.

http://www.dba-oracle.com/t_with_clause.htm

It requires some effort though. Don't be afraid to post a concrete example.

Using simple pseudo table DUAL helps too.

If you look at the scope of the variable 'hoursWorked' you will see that it is a member of the class (declared as private int)

The two variables you are having trouble with are passed as parameters to the constructor.

The error message is because 'hours' is out of scope in the setter.

<a href="#">
        <img src="p.png"></img>
    </a>

instead of using add() we can use addall()

{ seeAlso.addall(groupDn); }

add adds a single item, while addAll adds each item from the collection one by one. In the end, both methods return true if the collection has been modified. In case of ArrayList this is trivial, because the collection is always modified, but other collections, such as Set, may return false if items being added are already there.

It depends on what the zip contains. Take a look to see if it got content.jar and artifacts.jar. If it does, it is an archived updated site. Install from it the same way as you install from a remote site.

If the zip doesn't contain content.jar and artifacts.jar, go to your Eclipse install's dropins directory, create a subfolder (name doesn't matter) and expand your zip into that folder. Restart Eclipse.

How to prevent google colab from disconnecting

One difference from a debugging perspective:

To debug into Java system classes such as String and ArrayList, you need a special version of the JRE which is compiled with "debug information". The JRE included inside the JDK provides this info, but the regular JRE does not. Regular JRE does not include this info to ensure better performance.

What is debugging information? Here is a quick explanation taken from this blog post:

Modern compilers do a pretty good job converting your high-level code, with its nicely indented and nested control structures and arbitrarily typed variables into a big pile of bits called machine code (or bytecode in case of Java), the sole purpose of which is to run as fast as possible on the target CPU (virtual CPU of your JVM). Java code gets converted into several machine code instructions. Variables are shoved all over the place – into the stack, into registers, or completely optimized away. Structures and objects don’t even exist in the resulting code – they’re merely an abstraction that gets translated to hard-coded offsets into memory buffers.

So how does a debugger know where to stop when you ask it to break at the entry to some function? How does it manage to find what to show you when you ask it for the value of a variable? The answer is – debugging information.

Debugging information is generated by the compiler together with the machine code. It is a representation of the relationship between the executable program and the original source code. This information is encoded into a pre-defined format and stored alongside the machine code. Many such formats were invented over the years for different platforms and executable files.

The most simple and the correct way is to use Record type Record<string, string>

const myVar : Record<string, string> = {
   key1: 'val1',
   key2: 'val2',
}

use this

if (userProfile.AccountType == AccountType.Retailer)
{
     ...
}

If you want to get int from your AccountType enum and compare it (don't know why) do this:

if((int)userProfile.AccountType == 1)
{ 
     ...
}

Objet reference not set to an instance of an object exception is because your userProfile is null and you are getting property of null. Check in debug why it's not set.

EDIT (thanks to @Rik and @KonradMorawski) :

Maybe you can do some check before:

if(userProfile!=null)
{
}

or

if(userProfile==null)
{
   throw new ArgumentNullException(nameof(userProfile)); // or any other exception
}

cURL > 7.18.0 has an option --data-urlencode which solves this problem. Using this, I can simply send a POST request as

curl -d name=john --data-urlencode passwd=@31&3*J https://www.mysite.com

I tried some of the other answers here, but originalEvent was also undefined. Upon inspection, found a TouchList classed property (as suggested by another poster) and managed to get to pageX/Y this way:

var x = e.changedTouches[0].pageX;

Simply using ImageButton instead of Button fixes the problem.

<ImageButton android:layout_width="30dp"
             android:layout_height="30dp"
             android:src="@drawable/bgimage" />

and you can set

android:background="@null"

to remove button background if you want.

Quick Fix !! :-)

EDIT: The canonical way using newer JavaScript features is -

const identity = x =>
  x

const omap = (f = identity, o = {}) =>
  Object.fromEntries(
    Object.entries(o).map(([ k, v ]) =>
      [ k, f(v) ]
    )
  )

Where o is some object and f is your mapping function. Or we could say, given a function from a -> b, and an object with values of type a, produce an object with values of type b. As a pseudo type signature -

// omap : (a -> b, { a }) -> { b }

The original answer was written to demonstrate a powerful combinator, mapReduce which allows us to think of our transformation in a different way

1. m, the mapping function – gives you a chance to transform the incoming element before…
2. r, the reducing function – this function combines the accumulator with the result of the mapped element

Intuitively, mapReduce creates a new reducer we can plug directly into Array.prototype.reduce. But more importantly, we can implement our object functor implementation omap plainly by utilizing the object monoid, Object.assign and {}.

const identity = x =>_x000D_
  x_x000D_
  _x000D_
const mapReduce = (m, r) =>_x000D_
  (a, x) => r (a, m (x))_x000D_
_x000D_
const omap = (f = identity, o = {}) =>_x000D_
  Object_x000D_
    .keys (o)_x000D_
    .reduce_x000D_
      ( mapReduce_x000D_
          ( k => ({ [k]: f (o[k]) })_x000D_
          , Object.assign_x000D_
          )_x000D_
      , {}_x000D_
      )_x000D_
          _x000D_
const square = x =>_x000D_
  x * x_x000D_
  _x000D_
const data =_x000D_
  { a : 1, b : 2, c : 3 }_x000D_
  _x000D_
console .log (omap (square, data))_x000D_
// { a : 1, b : 4, c : 9 }

Notice the only part of the program we actually had to write is the mapping implementation itself –

k => ({ [k]: f (o[k]) })

Which says, given a known object o and some key k, construct an object and whose computed property k is the result of calling f on the key's value, o[k].

We get a glimpse of mapReduce's sequencing potential if we first abstract oreduce

// oreduce : (string * a -> string * b, b, { a }) -> { b }
const oreduce = (f = identity, r = null, o = {}) =>
  Object
    .keys (o)
    .reduce
      ( mapReduce
          ( k => [ k, o[k] ]
          , f
          )
      , r
      )

// omap : (a -> b, {a}) -> {b}
const omap = (f = identity, o = {}) =>
  oreduce
    ( mapReduce
        ( ([ k, v ]) =>
            ({ [k]: f (v) })
        , Object.assign
        )
    , {}
    , o
    )

Everything works the same, but omap can be defined at a higher-level now. Of course the new Object.entries makes this look silly, but the exercise is still important to the learner.

You won't see the full potential of mapReduce here, but I share this answer because it's interesting to see just how many places it can be applied. If you're interested in how it is derived and other ways it could be useful, please see this answer.

I simplify the code a little bit.

INSERT INTO t1 (a,b,c) VALUES (1,2,3),(4,5,6)
ON DUPLICATE KEY UPDATE c=VALUES(a)+VALUES(b);

You can read the tutorial below here :

https://mariadb.com/kb/en/library/insert-on-duplicate-key-update/

http://www.mysqltutorial.org/mysql-insert-or-update-on-duplicate-key-update/

Depending on some details you might need to do something like this:

r=$(pwd)
case "$TARG" in
    /*) p=$r;;
    *) p="";;
    esac
cd "$SRC" && cp -r . "$p/$TARG"
cd "$r"

... this basically changes to the SRC directory and copies it to the target, then returns back to whence ever you started.

The extra fussing is to handle relative or absolute targets.

(This doesn't rely on subtle semantics of the cp command itself ... about how it handles source specifications with or without a trailing / ... since I'm not sure those are stable, portable, and reliable beyond just GNU cp and I don't know if they'll continue to be so in the future).

Pickle is best for these cases. Suppose you have a ndarray named x_train. You can dump it into a file and revert it back using the following command:

import pickle

###Load into file
with open("myfile.pkl","wb") as f:
    pickle.dump(x_train,f)

###Extract from file
with open("myfile.pkl","rb") as f:
    x_temp = pickle.load(f)

netstat -l (assuming it comes with that version of UNIX)

As of Spark 2.4.3

val df = SparkSession.builder().getOrCreate().emptyDataFrame

Using Date pattern yyyy-MM-dd'T'HH:mm:ss.SSS'Z' and Java 8 you could do

String string = "2018-04-10T04:00:00.000Z";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
LocalDate date = LocalDate.parse(string, formatter);
System.out.println(date);

Update: For pre 26 use Joda time

String string = "2018-04-10T04:00:00.000Z";
DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
LocalDate date = org.joda.time.LocalDate.parse(string, formatter);

In app/build.gradle file, add like this-

dependencies {    
    compile 'joda-time:joda-time:2.9.4'
}

You need to add an additional parameter:

$http.get(url).then(
    function(response) {
        console.log('get',response)
    },
    function(data) {
        // Handle error here
    })

At least on Debian and all its derivatives, there is a 'sensible-browser' shell script which choose the browser best suited for the given url.

I think this is a file problem, you simple saved your file in 1-byte encoding like latin-1. Google up your editor and how to set files to utf-8.

I wonder why there are editors that don't default to utf-8.

BernardSaucier has already given you an answer. My post is not an answer but an explanation as to why you shouldn't be using UsedRange.

UsedRange is highly unreliable as shown HERE

To find the last column which has data, use .Find and then subtract from it.

With Sheets("Sheet1")
    If Application.WorksheetFunction.CountA(.Cells) <> 0 Then
        lastCol = .Cells.Find(What:="*", _
                      After:=.Range("A1"), _
                      Lookat:=xlPart, _
                      LookIn:=xlFormulas, _
                      SearchOrder:=xlByColumns, _
                      SearchDirection:=xlPrevious, _
                      MatchCase:=False).Column
    Else
        lastCol = 1
    End If
End With

If lastCol > 8 Then
    'Debug.Print ActiveSheet.UsedRange.Columns.Count - 8

    'The above becomes

    Debug.Print lastCol - 8
End If

You should notice that this depends on how function is invoked ie: when a function is called as a method of an object, its this is set to the object the method is called on.

this is accessible in JSX context as your component object, so you can call your desired method inline as this method.

If you just pass reference to function/method, it seems that react will invoke it as independent function.

onClick={this.onToggleLoop} // Here you just passing reference, React will invoke it as independent function and this will be undefined

onClick={()=>this.onToggleLoop()} // Here you invoking your desired function as method of this, and this in that function will be set to object from that function is called ie: your component object

Here is the analysis in the book Data Structures and Algorithm Analysis in C by Mark Allen Weiss (second edition, 2.4.4):

Euclid's algorithm works by continually computing remainders until 0 is reached. The last nonzero remainder is the answer.

Here is the code:

unsigned int Gcd(unsigned int M, unsigned int N)
{

    unsigned int Rem;
    while (N > 0) {
        Rem = M % N;
        M = N;
        N = Rem;
    }
    Return M;
}

Here is a THEOREM that we are going to use:

If M > N, then M mod N < M/2.

PROOF:

There are two cases. If N <= M/2, then since the remainder is smaller than N, the theorem is true for this case. The other case is N > M/2. But then N goes into M once with a remainder M - N < M/2, proving the theorem.

So, we can make the following inference:

Variables    M      N      Rem

initial      M      N      M%N

1 iteration  N     M%N    N%(M%N)

2 iterations M%N  N%(M%N) (M%N)%(N%(M%N)) < (M%N)/2

So, after two iterations, the remainder is at most half of its original value. This would show that the number of iterations is at most 2logN = O(logN).

Note that, the algorithm computes Gcd(M,N), assuming M >= N.(If N > M, the first iteration of the loop swaps them.)

Emacs expects one of db, sqlite, sqlite2 or sqlite3 in the default configuration for sql-sqlite mode.

Maybe you should try LocallyDB it's easy-to-use and lightweight in addition to the with advanced selecting system similar to javascript conditional expression...

https://github.com/btwael/locallydb

I had that problem too.

Try using Server.Transfer instead of Response.Redirect

Worked for me.

I believe, the 500ms run in the background, while the rest of the code continues to execute and empties the list.

Then after 500ms nothing happens, as no function-call is implemented in the after-callup (same as frame.after(500, function=None))

Return false will prevent navigation. Otherwise, the location would become the return value of someFunc

The answere by Patrick and by Jesse Chisholm made me do the following:

#define QUEEN 'Q'
#define JACK 'J'

#define CHECK_QUEEN(s) (s==QUEEN)
#define CHECK_JACK(s) (s==JACK)

#define USER 'Q'

[... later on in code ...]

#if CHECK_QUEEN(USER)
  compile_queen_func();
#elif CHECK_JACK(USER)
  compile_jack_func();
#elif
#error "unknown user"
#endif

Instead of #define USER 'Q' #define USER QUEEN should also work but was not tested also works and might be easier to handle.

It seems that your project is written in Python < 3. This is because the file() builtin function is removed in Python 3. Try using Python 2to3 tool or edit the erroneous file yourself.

EDIT: BTW, the project page clearly mentions that

Gunicorn requires Python 2.x >= 2.5. Python 3.x support is planned.

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

First add an Enrty and Category class:

public class Entry {     public string Id { get; set; }     public string Title { get; set; }     public string Updated { get; set; }     public string Summary { get; set; }     public string GPoint { get; set; }     public string GElev { get; set; }     public List<string> Categories { get; set; } }  public class Category {     public string Label { get; set; }     public string Term { get; set; } } 

Then use LINQ to XML

XDocument xDoc = XDocument.Load("path");          List<Entry> entries = (from x in xDoc.Descendants("entry")             select new Entry()             {                 Id = (string) x.Element("id"),                 Title = (string)x.Element("title"),                 Updated = (string)x.Element("updated"),                 Summary = (string)x.Element("summary"),                 GPoint = (string)x.Element("georss:point"),                 GElev = (string)x.Element("georss:elev"),                 Categories = (from c in x.Elements("category")                                   select new Category                                   {                                       Label = (string)c.Attribute("label"),                                       Term = (string)c.Attribute("term")                                   }).ToList();             }).ToList(); 

In Excel 2013 and resent versions, you can use F2 and F4 to speed things up when you want to toggle the lock.

About the keys:

• F2 - With a cell selected, it places the cell in formula edit mode.

• F4 - Toggles the cell reference lock (the $ signs).

• Example scenario with 'A4'.

  • Pressing F4 will convert 'A4' into '$A$4'
  • Pressing F4 again converts '$A$4' into 'A$4'
  • Pressing F4 again converts 'A$4' into '$A4'
  • Pressing F4 again converts '$A4' back to the original 'A4'

How To:

• In Excel, select a cell with a formula and hit F2 to enter formula edit mode. You can also perform these next steps directly in the Formula bar. (Issue with F2 ? Double check that 'F Lock' is on)

  • If the formula has one cell reference;
    • Hit F4 as needed and the single cell reference will toggle.
  • If the forumla has more than one cell reference, hitting F4 (without highlighting anything) will toggle the last cell reference in the formula.
  • If the formula has more than one cell reference and you want to change them all;
    • You can use your mouse to highlight the entire formula or you can use the following keyboard shortcuts;
    • Hit End key (If needed. Cursor is at end by default)
    • Hit Ctrl + Shift + Home keys to highlight the entire formula
    • Hit F4 as needed
  • If the formula has more than one cell reference and you only want to edit specific ones;
    • Highlight the specific values with your mouse or keyboard ( Shift and arrow keys) and then hit F4 as needed.

Notes:

• These notes are based on my observations while I was looking into this for one of my own projects.
• It only works on one cell formula at a time.
• Hitting F4 without selecting anything will update the locking on the last cell reference in the formula.
• Hitting F4 when you have mixed locking in the formula will convert everything to the same thing. Example two different cell references like '$A4' and 'A$4' will both become 'A4'. This is nice because it can prevent a lot of second guessing and cleanup.
• Ctrl+A does not work in the formula editor but you can hit the End key and then Ctrl + Shift + Home to highlight the entire formula. Hitting Home and then Ctrl + Shift + End.
• OS and Hardware manufactures have many different keyboard bindings for the Function (F Lock) keys so F2 and F4 may do different things. As an example, some users may have to hold down you 'F Lock' key on some laptops.
• 'DrStrangepork' commented about F4 actually closes Excel which can be true but it depends on what you last selected. Excel changes the behavior of F4 depending on the current state of Excel. If you have the cell selected and are in formula edit mode (F2), F4 will toggle cell reference locking as Alexandre had originally suggested. While playing with this, I've had F4 do at least 5 different things. I view F4 in Excel as an all purpose function key that behaves something like this; "As an Excel user, given my last action, automate or repeat logical next step for me".

Requested format in one line - no libraries and no Date methods, just regex:

var d = (new Date()).toString().replace(/\S+\s(\S+)\s(\d+)\s(\d+)\s.*/,'$2-$1-$3');
// date will be formatted as "14-Oct-2015" (pass any date object in place of 'new Date()')

In my testing, this works reliably in the major browsers (Chrome, Safari, Firefox and IE.) As @RobG pointed out, the output of Date.prototype.toString() is implementation-dependent, so for international or non-browser implementations, just test the output to be sure it works right in your JavaScript engine. You can even add some code to test the string output and make sure it's matching what you expect before you do the regex replace.

I'm guessing you're running python3, in which input(prompt) returns a string. Try this.

x=int(input('prompt'))
y=int(input('prompt'))

Short answer: No.

The switch statement takes an expression that is only evaluated once. Based on the result, another piece of code is executed.

So what? => String.StartsWith is a function. Together with a given parameter, it is an expression. However, for your case you need to pass a different parameter for each case, so it cannot be evaluated only once.

Long answer #1 has been given by others.

Long answer #2:

Depending on what you're trying to achieve, you might be interested in the Command Pattern/Chain-of-responsibility pattern. Applied to your case, each piece of code would be represented by an implementation of a Command. In addition to the execute method, the command can provide a boolean Accept method, which checks whether the given string starts with the respective parameter.

Advantage: Instead of your hardcoded switch statement, hardcoded StartsWith evaluations and hardcoded strings, you'd have lot more flexibility.

The example you gave in your question would then look like this:

var commandList = new List<Command>() { new MyABCCommand() };

foreach (Command c in commandList)
{
    if (c.Accept(mystring))
    {
        c.Execute(mystring);
        break;
    }
}

class MyABCCommand : Command
{
    override bool Accept(string mystring)
    {
        return mystring.StartsWith("abc");
    }
}    

Here's a google chrome extension that'll allow you to download your reviews: https://chrome.google.com/webstore/detail/my-play-store-reviews/ldggikfajgoedghjnflfafiiheagngoa?hl=en

As others have said, # coding: specifies the encoding the source file is saved in. Here are some examples to illustrate this:

A file saved on disk as cp437 (my console encoding), but no encoding declared

b = 'über'
u = u'über'
print b,repr(b)
print u,repr(u)

Output:

  File "C:\ex.py", line 1
SyntaxError: Non-ASCII character '\x81' in file C:\ex.py on line 1, but no
encoding declared; see http://www.python.org/peps/pep-0263.html for details

Output of file with # coding: cp437 added:

über '\x81ber'
über u'\xfcber'

At first, Python didn't know the encoding and complained about the non-ASCII character. Once it knew the encoding, the byte string got the bytes that were actually on disk. For the Unicode string, Python read \x81, knew that in cp437 that was a ü, and decoded it into the Unicode codepoint for ü which is U+00FC. When the byte string was printed, Python sent the hex value 81 to the console directly. When the Unicode string was printed, Python correctly detected my console encoding as cp437 and translated Unicode ü to the cp437 value for ü.

Here's what happens with a file declared and saved in UTF-8:

++ber '\xc3\xbcber'
über u'\xfcber'

In UTF-8, ü is encoded as the hex bytes C3 BC, so the byte string contains those bytes, but the Unicode string is identical to the first example. Python read the two bytes and decoded it correctly. Python printed the byte string incorrectly, because it sent the two UTF-8 bytes representing ü directly to my cp437 console.

Here the file is declared cp437, but saved in UTF-8:

++ber '\xc3\xbcber'
++ber u'\u251c\u255dber'

The byte string still got the bytes on disk (UTF-8 hex bytes C3 BC), but interpreted them as two cp437 characters instead of a single UTF-8-encoded character. Those two characters where translated to Unicode code points, and everything prints incorrectly.

The -maxdepth option should be before the -name option, like below.,

find . -maxdepth 1 -name "string" -print

I know this is hyper-optimization land, but it seemed like a good excuse to kick the wheels of BenchmarkDotNet. The result of this test (on .NET Core even) is that Substring is ever so slightly faster than Remove, in this sample test: 19.37ns vs 22.52ns for Remove. So some ~16% faster.

using System;
using BenchmarkDotNet.Attributes;

namespace BenchmarkFun
{
    public class StringSubstringVsRemove
    {
        public readonly string SampleString = " My name is Daffy Duck.";

        [Benchmark]
        public string StringSubstring() => SampleString.Substring(1);

        [Benchmark]
        public string StringRemove() => SampleString.Remove(0, 1);

        public void AssertTestIsValid()
        {
            string subsRes = StringSubstring();
            string remvRes = StringRemove();

            if (subsRes == null
                || subsRes.Length != SampleString.Length - 1
                || subsRes != remvRes) {
                throw new Exception("INVALID TEST!");
            }
        }
    }

    class Program
    {
        static void Main()
        {
            // let's make sure test results are really equal / valid
            new StringSubstringVsRemove().AssertTestIsValid();

            var summary = BenchmarkRunner.Run<StringSubstringVsRemove>();
        }
    }
}

Fine then. You can use CSS word wrap property. Something like this :

td.test /* Give whatever class name you want */
{
width:11em; /* Give whatever width you want */
word-wrap:break-word;
}

Simply add as first option of your select tag:

<option disabled hidden value=''></option>

This will become default and when you'll select a valid option will be setted on your state

You have to set the runtime for your web project to the Tomcat installation you are using; you can do it in the "Targeted runtimes" section of the project configuration.

In this way you will allow Eclipse to add Tomcat's Java EE Web Profile jars to the build path.

Remember that the HttpServlet class isn't in a JRE, but at least in an Enterprise Web Profile (e.g. a servlet container runtime /lib folder).

Does the following exclude the redirection that is .htacess that will run the $ this-> input- > post ('name' ) on the controller, in my case it worked perfectly .

abs, José Camargo]

the default encoding of a HTTP POST is ISO-8859-1.

else you have to look at the Content-Type header that will then look like

Content-Type: application/x-www-form-urlencoded ; charset=UTF-8

You can maybe declare your form with

<form enctype="application/x-www-form-urlencoded;charset=UTF-8">

or

<form accept-charset="UTF-8">

to force the encoding.

Some references :

http://www.htmlhelp.com/reference/html40/forms/form.html

You can only send 1 object as a parameter in the body via post. I would change your Post method to

public void Post(ICollection<Product> products)
{
}

and in your angular code you would pass up a product array in JSON notation

the above code for chrome is working fine. i have tried like this in mozila but its not working. i found the solution for that

For mozila

I ended up doing the following and it works:

return DatabaseContext.Applications
     .Include("Children.ChildRelationshipType");

Thread wait on the monitoring object (object used by synchronization block), There can be n number of monitoring object in whole journey of a single thread. If Thread wait outside the synchronization block then there is no monitoring object and also other thread notify to access for the monitoring object, so how would the thread outside the synchronization block would know that it has been notified. This is also one of the reason that wait(), notify() and notifyAll() are in object class rather than thread class.

Basically the monitoring object is common resource here for all the threads, and monitoring objects can only be available in synchronization block.

class A {
   int a = 0;
  //something......
  public void add() {
   synchronization(this) {
      //this is your monitoring object and thread has to wait to gain lock on **this**
       }
  }

Adding to what b_levitt said, you can get the SSDT-BI plugin for Visual Studio 2013 here: http://www.microsoft.com/en-us/download/details.aspx?id=42313

Here is one solution that I would not recommend, but might be useful in some situations where modules were simply not generated:

import os
import sys
parent_dir_name = os.path.dirname(os.path.dirname(os.path.realpath(__file__)))
sys.path.append(parent_dir_name + "/your_dir")
import your_script
your_script.a_function()

You can try this, and if it will find any space it will return the position where the first space is.

if mystring.find(' ') != -1:
    print True
else:
    print False

say your array is called arr

do

arr[arr.Length - 1]

An answer from AlexGo did the trick for me:

getActivity().runOnUiThread(new Runnable() {
        @Override
        public void run() {
         messages.add(m);
         adapter.notifyDataSetChanged();
         getListView().setSelection(messages.size()-1);
        }
});

List Update worked for me before when the update was triggered from a GUI event, thus being in the UI thread.

However, when I update the list from another event/thread - i.e. a call from outside the app, the update would not be in the UI thread and it ignored the call to getListView. Calling the update with runOnUiThread as above did the trick for me. Thanks!!

Since this is the top result on Google:

If your connection works initially, but you begin seeing this error after many successful connections, it may be this issue.

In summary: if you open and close a connection, Windows reserves the TCP port for future use for some stupid reason. After doing this many times, it runs out of available ports.

The article gives a registry hack to fix the issue...

Here are my registry settings on XP/2003:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\MaxUserPort 0xFFFF (DWORD)
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\MaxUserPort\TcpTimedWaitDelay 60 (DWORD)

You need to create them. By default they don't exists.

On Vista/2008 you can use netsh to change it to something like:

netsh int ipv4 set dynamicport tcp start=10000 num=50000

...but the real solution is to use connection pooling, so that "opening" a connection really reuses an existing connection. Most frameworks do this automatically, but in my case the application was handling connections manually for some reason.

PHP's strlen() function returns the number of ASCII characters.

strlen('borsc') -> 5 (bytes)

strlen('boršc') -> 7 (bytes)

$limit_in_kBytes = 20000;

$pointer = 0;
while(strlen($your_string) > (($pointer + 1) * $limit_in_kBytes)){
    $str_to_handle = substr($your_string, ($pointer * $limit_in_kBytes ), $limit_in_kBytes);
    // here you can handle (0 - n) parts of string
    $pointer++;
}

$str_to_handle = substr($your_string, ($pointer * $limit_in_kBytes), $limit_in_kBytes);
// here you can handle last part of string

.. or you can use a function like this:

function parseStrToArr($string, $limit_in_kBytes){
    $ret = array();

    $pointer = 0;
    while(strlen($string) > (($pointer + 1) * $limit_in_kBytes)){
        $ret[] = substr($string, ($pointer * $limit_in_kBytes ), $limit_in_kBytes);
        $pointer++;
    }

    $ret[] = substr($string, ($pointer * $limit_in_kBytes), $limit_in_kBytes);

    return $ret;
}

$arr = parseStrToArr($your_string, $limit_in_kBytes = 20000);

The common convention would be to put it in a .sh file that looks like this -

#!/bin/bash
java -cp  ".;./supportlibraries/Framework_Core.jar;... etc

Note that '\' become '/'.

You could execute as

sh myfile.sh

or set the x bit on the file

chmod +x myfile.sh

and then just call

myfile.sh

Use component scanning as given below, if com.project.action.PasswordHintAction is annotated with stereotype annotations

<context:component-scan base-package="com.project.action"/>

EDIT

I see your problem, in PasswordHintActionTest you are autowiring PasswordHintAction. But you did not create bean configuration for PasswordHintAction to autowire. Add one of stereotype annotation(@Component, @Service, @Controller) to PasswordHintAction like

@Component
public class PasswordHintAction extends BaseAction {
    private static final long serialVersionUID = -4037514607101222025L;
    private String username;

or create xml configuration in applicationcontext.xml like

<bean id="passwordHintAction" class="com.project.action.PasswordHintAction" />

I decided to write a class from this thread that may be helpful to others. Note that this is currently intended to write in the "files" directory only (e.g. does not write to "sdcard" paths).

I know it has been quite sometime that you asked this but, if someone else needs, I did what was saying here " How to upload a project to Github " and after the top answer of this question right here. And after was the top answer was saying here "git error: failed to push some refs to" I don't know what exactly made everything work. But now is working.

Your printf needs a format string:

printf("%d\n", x);

This reference page gives details on how to use printf and related functions.

Using

@Scripts.Render("~/scripts/myScript.js")

or

@Styles.Render("~/styles/myStylesheet.css")

could work for you.

One of the common problems with VLOOKUP is "data mismatch" where #N/A is returned because a numeric lookup value doesn't match a text-formatted value in the VLOOKUP table (or vice versa)

Does either of these versions work?

=VLOOKUP(M3&"",Sheet1!$A$2:$Q$47,13,FALSE)

or

=VLOOKUP(M3+0,Sheet1!$A$2:$Q$47,13,FALSE)

The former converts a numeric lookup value to text (assuming that lookup table 1st column contains numbers formatted as text). The latter does the reverse, changing a text-formatted lookup value to a number.

Depending on which one works (assuming one does) then you may want to permanently change the format of your data so that the standard VLOOKUP will work

You shouldn't change the npm registry using .bat files. Instead try to use modify the .npmrc file which is the configuration for npm. The correct command for changing registry is

npm config set registry <registry url>

you can find more information with npm help config command, also check for privileges when and if you are running .bat files this way.

For example:

import glob
lst_img = []
base_dir = '/home/xy/img/'

# get all the jpg file in base_dir 
lst_img += glob.glob(base_dir + '*.jpg')
print lst_img
# ['/home/xy/img/2.jpg', '/home/xy/img/1.jpg']

# append all the png file in base_dir to lst_img
lst_img += glob.glob(base_dir + '*.png')
print lst_img
# ['/home/xy/img/2.jpg', '/home/xy/img/1.jpg', '/home/xy/img/3.png']

A function:

import glob
def get_files(base_dir='/home/xy/img/', lst_extension=['*.jpg', '*.png']):
    """
    :param base_dir:base directory
    :param lst_extension:lst_extension: list like ['*.jpg', '*.png', ...]
    :return:file lists like ['/home/xy/img/2.jpg','/home/xy/img/3.png']
    """
    lst_files = []
    for ext in lst_extension:
        lst_files += glob.glob(base_dir+ext)
    return lst_files

if(values >= 0) {
 // as zero is more likely positive than negative
} else {

}

Projects created in Xcode 11 and above, simply changing the Main Interface file from the project settings won't be enough.

You have to manually edit the Info.plist file and set the storyboard name for the UISceneStoryboardFile as well.

Paste this into your CMakeLists.txt:

# find python
execute_process(COMMAND python-config --prefix OUTPUT_VARIABLE PYTHON_SEARCH_PATH)
string(REGEX REPLACE "\n$" "" PYTHON_SEARCH_PATH "${PYTHON_SEARCH_PATH}")
file(GLOB_RECURSE PYTHON_DY_LIBS ${PYTHON_SEARCH_PATH}/lib/libpython*.dylib ${PYTHON_SEARCH_PATH}/lib/libpython*.so)
if (PYTHON_DY_LIBS)
    list(GET PYTHON_DY_LIBS 0 PYTHON_LIBRARY)
    message("-- Find shared libpython: ${PYTHON_LIBRARY}")
else()
    message(WARNING "Cannot find shared libpython, try find_package")
endif()

find_package(PythonInterp)
find_package(PythonLibs ${PYTHON_VERSION_STRING} EXACT)

C++11 has some portable timer stuff. Check out sleep_for.

I had the same error in nodejs. But adding signatureVersion in s3 constructor helped me:

const s3 = new AWS.S3({
  apiVersion: '2006-03-01',
  signatureVersion: 'v4',
});

Your only option is to somehow clone the object.

See this stackoverflow question on how you can achieve this.

For simple JSON objects, the simplest way would be:

var newObject = JSON.parse(JSON.stringify(oldObject));

if you use jQuery, you can use:

// Shallow copy
var newObject = jQuery.extend({}, oldObject);

// Deep copy
var newObject = jQuery.extend(true, {}, oldObject);

UPDATE 2017: I should mention, since this is a popular answer, that there are now better ways to achieve this using newer versions of javascript:

In ES6 or TypeScript (2.1+):

var shallowCopy = { ...oldObject };

var shallowCopyWithExtraProp = { ...oldObject, extraProp: "abc" };

Note that if extraProp is also a property on oldObject, its value will not be used because the extraProp : "abc" is specified later in the expression, which essentially overrides it. Of course, oldObject will not be modified.

You are part right. with <b>title</b> it looks fine, but I would like to use <h4>.

I have put <h4 style="display: inline;"> and it seams to work.

Now, I only need to add some vertival align.

What I have done here is that I have returned a promise from the justTesting function. You can then get the result when the function is resolved.

// new answer

function justTesting() {
  return new Promise((resolve, reject) => {
    if (true) {
      return resolve("testing");
    } else {
      return reject("promise failed");
   }
 });
}

justTesting()
  .then(res => {
     let test = res;
     // do something with the output :)
  })
  .catch(err => {
    console.log(err);
  });

Hope this helps!

// old answer

function justTesting() {
  return promise.then(function(output) {
    return output + 1;
  });
}

justTesting().then((res) => {
     var test = res;
    // do something with the output :)
    }

Use a subselect:

SELECT row  FROM table  WHERE id=(
    SELECT max(id) FROM table
)

Note: ID must be unique, else multiple rows are returned

there is no native interfaces in JavaScript, there are several ways to simulate an interface. i have written a package that does it

The top-scoring answer has the right idea, but the API seems to have evolved so that it no longer works as when it was first written, in 2015.

In place of this:

from OpenSSL import SSL
context = SSL.Context(SSL.PROTOCOL_TLSv1_2)
context.use_privatekey_file('server.key')
context.use_certificate_file('server.crt')

I used this, with Python 3.7.5:

import ssl
context = ssl.SSLContext()
context.load_cert_chain('fullchain.pem', 'privkey.pem')

and then supplied the SSL context in the Flask.run call as it said:

app.run(…, ssl_context=context)

(My server.crt file is called fullchain.pem and my server.key is called privkey.pem. These files were supplied to me by my LetsEncrypt Certbot.)

A regex match with \s+ worked for me:

This will give you true if url does not return 200 OK

function check_404($url) {
   $headers=get_headers($url, 1);
   if ($headers[0]!='HTTP/1.1 200 OK') return true; else return false;
}

create user ro_role identified by ro_role;
grant create session, select any table, select any dictionary to ro_role;

Use "This is' it".replace("'", "\\'")

1. Start your MySQL server service from MySQL home directory. Your one is C:\MYSQL\bin\ so choose this directory in command line and type: NET START MySQL
   (After that you can open Windows Task Manager and verify in Processes tab is mysqld.exe process running. Maybe your problem is here.)
2. Type: mysql -u user -p [pressEnter]
3. Type your password [pressEnter]

or make a start.bat file:

1. add C:\MYSQL\bin\ to your PATH
2. write a start.bat file
My start.bat file has only two lines like below:
net start MySQL
mysql -u root -p

Good luck!

I am using

bin(1)[2:].zfill(8)

will print

'00000001'

The const modifier is applied to the term immediately to its left. The only exception to this is when there is nothing to its left, then it applies to what is immediately on its right.

These are all equivalent ways of saying "constant pointer to a constant char":

• const char * const
• const char const *
• char const * const
• char const const *

Copy and paste below code into AppDelegate.m to print the device APN token.

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
  NSUInteger dataLength = deviceToken.length;
  if (dataLength == 0) {
    return;
  }
  const unsigned char *dataBuffer = (const unsigned char *)deviceToken.bytes;
  NSMutableString *hexString  = [NSMutableString stringWithCapacity:(dataLength * 2)];
  for (int i = 0; i < dataLength; ++i) {
    [hexString appendFormat:@"%02x", dataBuffer[i]];
  }
  NSLog(@"APN token:%@", hexString);
}

You can quote the entire path as in windows or you can escape the spaces like in:

/foo\ folder\ with\ space/foo.sh -help

Both ways will work!

On your local repository you can install your jar by issuing the commands

 mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> \
-DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging>

Follow this useful link to do the same from mkyoung's website. You can also check maven guide for the same

Just in case there's anyone here using netbeans and has the same problem, all you have to do is

• Right click on TestLibraries
• Click on Add Library
• Select JUnit and click add library
• Repeat the process but this time click on Hamcrest and the click add library

This should solve the problem

To print your context ,you can write code like this :

FILE *fp;
char *of;
sprintf(of,"%s%s",text1,text2);
fp=fopen(of,'w');
fprintf(fp,"your print line");

A "Login" grants the principal entry into the SERVER.

A "User" grants a login entry into a single DATABASE.

One "Login" can be associated with many users (one per database).

Each of the above objects can have permissions granted to it at its own level. See the following articles for an explanation of each

• Principals
• Database Users
