Have you tried the following:

SELECT ID, COUNT(*), max(date)
FROM table 
GROUP BY ID;

For all cases, not just for these versions or libraries:

Pay attention to the little information window that say something about the error, it says the examples that you have to change and add.

In this case:

Found versions 25.1.1, 24.0.0. Examples include com.android.support:animated-vector-drawable:25.1.1 and com.android.support:mediarouter-v7:24.0.0

Your

com.android.support:animated-vector-drawable:25.1.1

is version 25.1.1, and your

com.android.support:mediarouter-v7:24.0.0

is version 24.0.0, so you have to add the mediarouter with the same version:

com.android.support:mediarouter-v7:25.1.1

And do that for every example that the little information window says, in this case all the libraries that doesn't have the version 25.1.1.

You have to sync the gradle after you fix the indicated library to see the next library and package that you have to change.

IMPORTANT:

If you are not explicitly using one or more specified libraries and it is giving you the error, it means that is being used internally by another library, compile it explicitly anyway.

You also can use another method to see the difference of the versions of all the libraries that you are actually compiling (like run a gradle dependency report or go to your libraries files), the real objetive is compile all the libraries that you are using with the same version.

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)

                      lyear = true;
                  }
                  if ((lyear==false) && (dd>=29))
                  {
                      alert('Invalid date format!');
                      return false;
                  }
                  if ((lyear==true) && (dd>29))
                  {
                      alert('Invalid date format!');
                      return false;
                  }
              }
          }
          else
          {
              alert("Invalid date format!");

              return false;
          }
       });
   });

This is more a long comment on @Sergey and @Steffen's answers. Having written similar code myself in the past I decided to check what was most performant while remembering that clarity is important too.

Result

Here is an example test run result for 10 million iterations:

2257 ms for FirstDayOfMonth_AddMethod()
2406 ms for FirstDayOfMonth_NewMethod()
6342 ms for LastDayOfMonth_AddMethod()
4037 ms for LastDayOfMonth_AddMethodWithDaysInMonth()
4160 ms for LastDayOfMonth_NewMethod()
4212 ms for LastDayOfMonth_NewMethodWithReuseOfExtMethod()
2491 ms for LastDayOfMonth_SpecialCase()

Code

I used LINQPad 4 (in C# Program mode) to run the tests with compiler optimization turned on. Here is the tested code factored as Extension methods for clarity and convenience:

public static class DateTimeDayOfMonthExtensions
{
    public static DateTime FirstDayOfMonth_AddMethod(this DateTime value)
    {
        return value.Date.AddDays(1 - value.Day);
    }
    
    public static DateTime FirstDayOfMonth_NewMethod(this DateTime value)
    {
        return new DateTime(value.Year, value.Month, 1);
    }
    
    public static DateTime LastDayOfMonth_AddMethod(this DateTime value)
    {
        return value.FirstDayOfMonth_AddMethod().AddMonths(1).AddDays(-1);
    }
    
    public static DateTime LastDayOfMonth_AddMethodWithDaysInMonth(this DateTime value)
    {
        return value.Date.AddDays(DateTime.DaysInMonth(value.Year, value.Month) - value.Day);
    }
    
    public static DateTime LastDayOfMonth_SpecialCase(this DateTime value)
    {
        return value.AddDays(DateTime.DaysInMonth(value.Year, value.Month) - 1);
    }
    
    public static int DaysInMonth(this DateTime value)
    {
        return DateTime.DaysInMonth(value.Year, value.Month);
    }
    
    public static DateTime LastDayOfMonth_NewMethod(this DateTime value)
    {
        return new DateTime(value.Year, value.Month, DateTime.DaysInMonth(value.Year, value.Month));
    }

    public static DateTime LastDayOfMonth_NewMethodWithReuseOfExtMethod(this DateTime value)
    {
        return new DateTime(value.Year, value.Month, value.DaysInMonth());
    }
}

void Main()
{
    Random rnd = new Random();
    DateTime[] sampleData = new DateTime[10000000];
    
    for(int i = 0; i < sampleData.Length; i++) {
        sampleData[i] = new DateTime(1970, 1, 1).AddDays(rnd.Next(0, 365 * 50));
    }
    
    GC.Collect();
    System.Diagnostics.Stopwatch sw = System.Diagnostics.Stopwatch.StartNew();
    for(int i = 0; i < sampleData.Length; i++) {
        DateTime test = sampleData[i].FirstDayOfMonth_AddMethod();
    }
    string.Format("{0} ms for FirstDayOfMonth_AddMethod()", sw.ElapsedMilliseconds).Dump();
    
    GC.Collect();
    sw.Restart();
    for(int i = 0; i < sampleData.Length; i++) {
        DateTime test = sampleData[i].FirstDayOfMonth_NewMethod();
    }
    string.Format("{0} ms for FirstDayOfMonth_NewMethod()", sw.ElapsedMilliseconds).Dump();
    
    GC.Collect();
    sw.Restart();
    for(int i = 0; i < sampleData.Length; i++) {
        DateTime test = sampleData[i].LastDayOfMonth_AddMethod();
    }
    string.Format("{0} ms for LastDayOfMonth_AddMethod()", sw.ElapsedMilliseconds).Dump();

    GC.Collect();
    sw.Restart();
    for(int i = 0; i < sampleData.Length; i++) {
        DateTime test = sampleData[i].LastDayOfMonth_AddMethodWithDaysInMonth();
    }
    string.Format("{0} ms for LastDayOfMonth_AddMethodWithDaysInMonth()", sw.ElapsedMilliseconds).Dump();

    GC.Collect();
    sw.Restart();
    for(int i = 0; i < sampleData.Length; i++) {
        DateTime test = sampleData[i].LastDayOfMonth_NewMethod();
    }
    string.Format("{0} ms for LastDayOfMonth_NewMethod()", sw.ElapsedMilliseconds).Dump();

    GC.Collect();
    sw.Restart();
    for(int i = 0; i < sampleData.Length; i++) {
        DateTime test = sampleData[i].LastDayOfMonth_NewMethodWithReuseOfExtMethod();
    }
    string.Format("{0} ms for LastDayOfMonth_NewMethodWithReuseOfExtMethod()", sw.ElapsedMilliseconds).Dump();

    for(int i = 0; i < sampleData.Length; i++) {
        sampleData[i] = sampleData[i].FirstDayOfMonth_AddMethod();
    }
    
    GC.Collect();
    sw.Restart();
    for(int i = 0; i < sampleData.Length; i++) {
        DateTime test = sampleData[i].LastDayOfMonth_SpecialCase();
    }
    string.Format("{0} ms for LastDayOfMonth_SpecialCase()", sw.ElapsedMilliseconds).Dump();
    
}

Analysis

I was surprised by some of these results.

Although there is not much in it the FirstDayOfMonth_AddMethod was slightly faster than FirstDayOfMonth_NewMethod in most runs of the test. However, I think the latter has a slightly clearer intent and so I have a preference for that.

LastDayOfMonth_AddMethod was a clear loser against LastDayOfMonth_AddMethodWithDaysInMonth, LastDayOfMonth_NewMethod and LastDayOfMonth_NewMethodWithReuseOfExtMethod. Between the fastest three there is nothing much in it and so it comes down to your personal preference. I choose the clarity of LastDayOfMonth_NewMethodWithReuseOfExtMethod with its reuse of another useful extension method. IMHO its intent is clearer and I am willing to accept the small performance cost.

LastDayOfMonth_SpecialCase assumes you are providing the first of the month in the special case where you may have already calculated that date and it uses the add method with DateTime.DaysInMonth to get the result. This is faster than the other versions, as you would expect, but unless you are in a desperate need for speed I don't see the point of having this special case in your arsenal.

Conclusion

Here is an extension method class with my choices and in general agreement with @Steffen I believe:

public static class DateTimeDayOfMonthExtensions
{
    public static DateTime FirstDayOfMonth(this DateTime value)
    {
        return new DateTime(value.Year, value.Month, 1);
    }
    
    public static int DaysInMonth(this DateTime value)
    {
        return DateTime.DaysInMonth(value.Year, value.Month);
    }
    
    public static DateTime LastDayOfMonth(this DateTime value)
    {
        return new DateTime(value.Year, value.Month, value.DaysInMonth());
    }
}

If you have got this far, thank you for time! Its been fun :¬). Please comment if you have any other suggestions for these algorithms.

The simplest I've found is using background jobs in the shell:

for d in /main/files/*; do
    rsync -a "$d" remote:/main/files/ &
done

Beware it doesn't limit the amount of jobs! If you're network-bound this is not really a problem but if you're waiting for spinning rust this will be thrashing the disk.

You could add

while [ $(jobs | wc -l | xargs) -gt 10 ]; do sleep 1; done

inside the loop for a primitive form of job control.

Right Click > Open Folder in File Explorer

If you are in the directory, find Global.asax not the Global.asax.cs

Right click on Global.asax file then find Open with

Change Inherits="ProjectNameThatHasError.MvcApplication" to Inherits="YourNamespaceNow.MvcApplication"

You can open it in Notepad, Visual Studio any version, anyways you'll be editing text.

Another CSS-only solution (though data-attribute is needed if you don't want to write letter-specific CSS). This one works more across the board (Tested IE 9/10, Chrome latest & FF latest)

span {_x000D_
  position: relative;_x000D_
  color: rgba(50,50,200,0.5);_x000D_
}_x000D_
_x000D_
span:before {_x000D_
  content: attr(data-char);_x000D_
  position: absolute;_x000D_
  width: 50%;_x000D_
  overflow: hidden;_x000D_
  color: rgb(50,50,200);_x000D_
}

<span data-char="X">X</span>

I listed dates of 2 Weeks later. You can use variable @period OR function datediff(dd, @date_start, @date_end)

declare @period INT, @date_start datetime, @date_end datetime, @i int;

set @period = 14
set @date_start = convert(date,DATEADD(D, -@period, curent_timestamp))
set @date_end = convert(date,current_timestamp)
set @i = 1

create table #datesList(dts datetime)
insert into #datesList values (@date_start)
while @i <= @period
    Begin
        insert into #datesList values (dateadd(d,@i,@date_start))
        set @i = @i + 1
    end
select cast(dts as DATE) from #datesList
Drop Table #datesList

Below are some of the way by which you can create a link button in MVC.

@Html.ActionLink("Admin", "Index", "Home", new { area = "Admin" }, null)  
@Html.RouteLink("Admin", new { action = "Index", controller = "Home", area = "Admin" })  
@Html.Action("Action", "Controller", new { area = "AreaName" })  
@Url.Action("Action", "Controller", new { area = "AreaName" })  
<a class="ui-btn" data-val="abc" href="/Home/Edit/ANTON">Edit</a>  
<a data-ajax="true" data-ajax-method="GET" data-ajax-mode="replace" data-ajax-update="#CustomerList" href="/Home/Germany">Customer from Germany</a>  
<a data-ajax="true" data-ajax-method="GET" data-ajax-mode="replace" data-ajax-update="#CustomerList" href="/Home/Mexico">Customer from Mexico</a> 

Hope this will help you.

datepicker doesnot have a maxDate as an option.I used this endDate option.It worked well.

> $('.demo-calendar-default').datepicker({
>                 autoHide: true,
>                 zIndex: 2048,
>                 format: 'dd/mm/yyyy',
>                 endDate: new Date()
>             });

HttpClient is the newer of the APIs and it has the benefits of

• has a good async programming model
• being worked on by Henrik F Nielson who is basically one of the inventors of HTTP, and he designed the API so it is easy for you to follow the HTTP standard, e.g. generating standards-compliant headers
• is in the .Net framework 4.5, so it has some guaranteed level of support for the forseeable future
• also has the xcopyable/portable-framework version of the library if you want to use it on other platforms - .Net 4.0, Windows Phone etc.

If you are writing a web service which is making REST calls to other web services, you should want to be using an async programming model for all your REST calls, so that you don't hit thread starvation. You probably also want to use the newest C# compiler which has async/await support.

Note: It isn't more performant AFAIK. It's probably somewhat similarly performant if you create a fair test.

Just remove tabindex="-1" and add style overflow:hidden

Here is an example:

<div id="myModal" class="modal fade" role="dialog" style="overflow:hidden;">
    <!---content modal here -->
</div>

In Microsoft ASP.net MVC, the routing engine, which is used to parse incoming and outgoing URL Combinations, is designed with the idea of Convention over Configuration. What this means is that if you follow the Convention (rules) that the routing engine uses, you don't have to change the Configuration.

The routing engine for ASP.net MVC does not serve web pages (.cshtml). It provides a way for a URL to be handled by a Class in your code, which can render text/html to the output stream, or parse and serve the .cshtml files in a consistent manner using Convention.

The Convention which is used for routing is to match a Controller to a Class with a name similar to ControllerNameController i.e. controller="MyAccount" means find class named MyAccountController. Next comes the action, which is mapped to a function within the Controller Class, which usually returns an ActionResult. i.e. action="LoginRegister" will look for a function public ActionResult LoginRegister(){} in the controller's class. This function may return a View() which would be by Convention named LoginRegister.cshtml and would be stored in the /Views/MyAccount/ folder.

To summarize, you would have the following code:

/Controllers/MyAccountController.cs:

public class MyAccountController : Controller 
{
    public ActionResult LoginRegister()
    {
        return View();
    }
}

/Views/MyAccount/LoginRegister.cshtml: Your view file.

I am on Laravel 7.25 and I don't know if it supports on previous versions or not but Its pretty good.

Syntax for the function:

public function joinSub($query, $as, $first, $operator = null, $second = null, $type = 'inner', $where = false)

Showing/Getting the user ID and the total number of posts by them left joining two tables users and posts.

        return DB::table('users')
            ->joinSub('select user_id,count(id) noOfPosts from posts group by user_id', 'totalPosts', 'users.id', '=', 'totalPosts.user_id', 'left')
            ->select('users.name', 'totalPosts.noOfPosts')
            ->get();

Alternative:

If you don't wanna mention 'left' for leftjoin then you can use another prebuilt function

    public function leftJoinSub($query, $as, $first, $operator = null, $second = null)
    {
        return $this->joinSub($query, $as, $first, $operator, $second, 'left');
    }

And yeah, it actually calls the same function but it passes the join type itself. You can apply the same logic for other joins i.e. righJoinSub(...) etc.

Some useful examples:

count files in current dir

/bin/ls -lA  | egrep -c '^-'

count dirs in current dir

/bin/ls -lA  | egrep -c '^d'

count files and dirs in current dir

/bin/ls -lA  | egrep -c '^-|^d'

count files and dirs in in one subdirectory

/bin/ls -lA  subdir_name/ | egrep -c '^-|^d'

I have noticed a strange thing (at least in my case) :

When I have tried with ls instead /bin/ls the -A parameter do not list implied . and .. NOT WORK as espected. When I use ls that show ./ and ../ So that result wrong count. SOLUTION : /bin/ls instead ls

Different case but may help someone,

In my case Window firewall was enabled on Server,

Two thinks can be done,

1) Disable windows firewall (your on risk but it will get thing work)

2) Add port in inbound rule.

Thanks .

Error 0x8007000d means URL rewriting module (referenced in web.config) is missing or proper version is not installed.

Just install URL rewriting module via web platform installer.

I recommend to check all dependencies from web.config and install them.

In case you prefer to use jQuery to set the image from Base64:

$("#img").attr('src', 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==');

I know you are using Datepicker, but for some people who are just using HTML5 input date like me, there is an example how you can do the same: JSFiddle Link

$('#start_date').change(function(){
  var start_date = $(this).val();
  $('#end_date').prop({
    min: start_date
  });
});


/*  prop() method works since jquery 1.6, if you are using a previus version, you can use attr() method.*/

I'm posting a more declarative way of sync Base64 converting. While async fetch().blob() is very neat and I like this solution a lot, it doesn't work on Internet Explorer 11 (and probably Edge - I haven't tested this one), even with the polyfill - take a look at my comment to Endless' post for more details.

const blobPdfFromBase64String = base64String => {
   const byteArray = Uint8Array.from(
     atob(base64String)
       .split('')
       .map(char => char.charCodeAt(0))
   );
  return new Blob([byteArray], { type: 'application/pdf' });
};

Bonus

If you want to print it you could do something like:

const isIE11 = !!(window.navigator && window.navigator.msSaveOrOpenBlob); // Or however you want to check it
const printPDF = blob => {
   try {
     isIE11
       ? window.navigator.msSaveOrOpenBlob(blob, 'documents.pdf')
       : printJS(URL.createObjectURL(blob)); // http://printjs.crabbly.com/
   } catch (e) {
     throw PDFError;
   }
};

Bonus x 2 - Opening a BLOB file in new tab for Internet Explorer 11

If you're able to do some preprocessing of the Base64 string on the server you could expose it under some URL and use the link in printJS :)

I have done this in a project a long time ago. The code given below write a whole rows bold with specific column names and all of these columns are written in bold format.

private void WriteColumnHeaders(DataColumnCollection columnCollection, int row, int column)
    {
        // row represent particular row you want to bold its content.
        for (i = 0; i < columnCollection.Count; i++)
        {
            DataColumn col = columnCollection[i];
            xlWorkSheet.Cells[row, column + i + 1] = col.Caption;
            // Some Font Styles
            xlWorkSheet.Cells[row, column + i + 1].Style.Font.Bold = true;
            xlWorkSheet.Cells[row, column + i + 1].Interior.Color = Color.FromArgb(192, 192, 192);
            //xlWorkSheet.Columns[i + 1].ColumnWidth = xlWorkSheet.Columns[i+1].ColumnWidth + 10;
        }
    }

You must pass value of row 0 so that first row of your excel sheets have column headers with bold font size. Just change DataColumnCollection to your columns name and change col.Caption to specific column name.

Alternate

You may do this to cell of excel sheet you want bold.

xlWorkSheet.Cells[row, column].Style.Font.Bold = true;

This beautiful code here creates a table with each td having array values. Not my code, but it helped me!

var rows = 6, cols = 7;

for(var i = 0; i < rows; i++) {
  $('table').append('<tr></tr>');
  for(var j = 0; j < cols; j++) {
    $('table').find('tr').eq(i).append('<td></td>');
    $('table').find('tr').eq(i).find('td').eq(j).attr('data-row', i).attr('data-col', j);
  }
}

When you are using curl sometimes give you 403 (access forbidden) Solved by adding this line to emulate browser.

Hope this help someone.

My case had a different solution. The client was using basichttpsbinding[1] and the service was using wshttpbinding.

I resolved the problem by changing the server binding to basichttpsbinding. Also, i had to set target framework to 4.5 by adding:

  <system.web>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5"/>
  </system.web>

[1] the comunication was over https.

I set starting date using this method, because aforesaid or other codes didn't work for me

$(document).ready(function() {_x000D_
 $('#dateFrm').datepicker('setStartDate', new Date(yyyy, dd, MM));_x000D_
 });

Somewhere the code--either your code or a jQuery plugin--is calling $.browser to get the current browser type.

However, early has year the $.browser function was deprecated. Since then some bugs have been filed against it but because it is deprecated, the jQuery team has decided not to fix them. I've decided not to rely on the function at all.

I don't see any references to $.browser in your code, so the problem probably lies in one of your plugins. To find it, look at the source code for each plugin that you've referenced with a <script> tag.

As for how to fix it: well, it depends on the context. E.g., maybe there's an updated version of the problematic plugin. Or perhaps you can use another plugin that does something similar but doesn't depend on $.browser.

You need to set basicHttpBinding -> MaxReceivedMessageSize in the client configuration.

This is a bit late in the day for suggesting this, given how long ago the original question was posted, but this is what I did.

I needed a range of 70 years, which, while not as much as 100, is still too many years for the visitor to scroll through. (jQuery does step through year in groups, but that's a pain in the patootie for most people.)

The first step was to modify the JavaScript for the datepicker widget: Find this code in jquery-ui.js or jquery-ui-min.js (where it will be minimized):

for (a.yearshtml+='<select class="ui-datepicker-year" onchange="DP_jQuery_'+y+".datepicker._selectMonthYear('#"+
a.id+"', this, 'Y');\" onclick=\"DP_jQuery_"+y+".datepicker._clickMonthYear('#"+a.id+"');\">";b<=g;b++)
 a.yearshtml+='<option value="'+b+'"'+(b==c?' selected="selected"':"")+">"+b+"</option>";
a.yearshtml+="</select>";

And replace it with this:

a.yearshtml+='<select class="ui-datepicker-year" onchange="DP_jQuery_'+y+
 ".datepicker._selectMonthYear('#"+a.id+"', this, 'Y');
 \" onclick=\"DP_jQuery_"+y+".datepicker._clickMonthYear('#"+a.id+"');
 \">";
for(opg=-1;b<=g;b++) {
    a.yearshtml+=((b%10)==0 || opg==-1 ?
        (opg==1 ? (opg=0, '</optgroup>') : '')+
        (b<(g-10) ? (opg=1, '<optgroup label="'+b+' >">') : '') : '')+
        '<option value="'+b+'"'+(b==c?' selected="selected"':"")+">"+b+"</option>";
}
a.yearshtml+="</select>";

This surrounds the decades (except for the current) with OPTGROUP tags.

Next, add this to your CSS file:

.ui-datepicker OPTGROUP { font-weight:normal; }
.ui-datepicker OPTGROUP OPTION { display:none; text-align:right; }
.ui-datepicker OPTGROUP:hover OPTION { display:block; }

This hides the decades until the visitor mouses over the base year. Your visitor can scroll through any number of years quickly.

Feel free to use this; just please give proper attribution in your code.

To know the actual date format, insert a record by using sysdate. That way you can find the actual date format. for example

insert into emp values(7936, 'Mac', 'clerk', 7782, sysdate, 1300, 300, 10);

now, select the inserted record.

select ename, hiredate from emp where ename='Mac';

the result is

ENAME   HIREDATE
Mac     06-JAN-13

voila, now your actual date format is found.

You can use as below,

Select X.a, X.b, Y.c from (
                Select X.a as a, sum (b) as sum_b from name_table X
                group by X.a)X
left join from name_table Y on Y.a = X.a

Example;

CREATE TABLE #products (
    product_name VARCHAR(MAX),
    code varchar(3),
    list_price [numeric](8, 2) NOT NULL
);

INSERT INTO #products VALUES ('paku', 'ACE', 2000)
INSERT INTO #products VALUES ('paku', 'ACE', 2000)
INSERT INTO #products VALUES ('Dinding', 'ADE', 2000)
INSERT INTO #products VALUES ('Kaca', 'AKB', 2000)
INSERT INTO #products VALUES ('paku', 'ACE', 2000)

--SELECT * FROM #products 
SELECT distinct x.code, x.SUM_PRICE, product_name FROM (SELECT code, SUM(list_price) as SUM_PRICE From #products 
               group by code)x
left join #products y on y.code=x.code

DROP TABLE #products

Most answers and explanations are not to explain what is a valid string of endDate or startDate. Danny gave us two useful example.

$('#datepicker').datepicker({
    startDate: '-2m',
    endDate: '+2d'
});

But why?let's take a look at the source code at bootstrap-datetimepicker.js. There are some code begin line 1343 tell us how does it work.

if (/^[-+]\d+[dmwy]([\s,]+[-+]\d+[dmwy])*$/.test(date)) {
            var part_re = /([-+]\d+)([dmwy])/,
                parts = date.match(/([-+]\d+)([dmwy])/g),
                part, dir;
            date = new Date();
            for (var i = 0; i < parts.length; i++) {
                part = part_re.exec(parts[i]);
                dir = parseInt(part[1]);
                switch (part[2]) {
                    case 'd':
                        date.setUTCDate(date.getUTCDate() + dir);
                        break;
                    case 'm':
                        date = Datetimepicker.prototype.moveMonth.call(Datetimepicker.prototype, date, dir);
                        break;
                    case 'w':
                        date.setUTCDate(date.getUTCDate() + dir * 7);
                        break;
                    case 'y':
                        date = Datetimepicker.prototype.moveYear.call(Datetimepicker.prototype, date, dir);
                        break;
                }
            }
            return UTCDate(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(), date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds(), 0);
        }

There are four kinds of expressions.

• w means week
• m means month
• y means year
• d means day

Look at the regular expression ^[-+]\d+[dmwy]([\s,]+[-+]\d+[dmwy])*$. You can do more than these -0d or +1m.

Try harder like startDate:'+1y,-2m,+0d,-1w'.And the separator , could be one of [\f\n\r\t\v,]

you can also covert int to str first and assign index to it then again convert it to int like this:

int(str(x)[n]) //where x is an integer value

I wrote the following code to convert an image from sdcard to a Base64 encoded string to send as a JSON object.And it works great:

String filepath = "/sdcard/temp.png";
File imagefile = new File(filepath);
FileInputStream fis = null;
try {
    fis = new FileInputStream(imagefile);
    } catch (FileNotFoundException e) {
    e.printStackTrace();
}

Bitmap bm = BitmapFactory.decodeStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();  
bm.compress(Bitmap.CompressFormat.JPEG, 100 , baos);    
byte[] b = baos.toByteArray(); 
encImage = Base64.encodeToString(b, Base64.DEFAULT);

Just in case if for example you need to put a min date, the last 3 months and max date next 3 months

$('#id_your_date').datepicker({ 
   maxDate: '+3m',
   minDate: '-3m'
 });

try this:

select salesid,count (salesid) from AXDelNotesNoTracking group by salesid having count (salesid) >1

$( "#date" ).datetimepicker({startDate:new Date()}).datetimepicker('update', new Date());

new Date() : function get the todays date previous date are locked. 100% working

In JavaScript you cannot have the direct access to the filesystem. However, you can make browser to pop up a dialog window allowing the user to pick the save location. In order to do this, use the replace method with your Base64String and replace "image/png" with "image/octet-stream":

"data:image/png;base64,iVBORw0KG...".replace("image/png", "image/octet-stream");

Also, W3C-compliant browsers provide 2 methods to work with base64-encoded and binary data:

• atob()
• btoa()

Probably, you will find them useful in a way...

Here is a refactored version of what I understand you need:

window.addEventListener('DOMContentLoaded', () => {_x000D_
  const img = document.getElementById('embedImage');_x000D_
  img.src = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA' +_x000D_
    'AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO' +_x000D_
    '9TXL0Y4OHwAAAABJRU5ErkJggg==';_x000D_
_x000D_
  img.addEventListener('load', () => button.removeAttribute('disabled'));_x000D_
  _x000D_
  const button = document.getElementById('saveImage');_x000D_
  button.addEventListener('click', () => {_x000D_
    window.location.href = img.src.replace('image/png', 'image/octet-stream');_x000D_
  });_x000D_
});

In recent version, The following works fine:

    $('.selector').datetimepicker({
        maxDate: new Date()
    });

maxDate accepts a Date object as parameter.

The following found in documentation:

Multiple types supported:

• Date: A date object containing the minimum date.

• Number: A number of days from today. For example 2 represents two days from today and -1 represents yesterday.

• String: A string in the format defined by the dateFormat option, or a relative date. Relative dates must contain value and period pairs; valid periods are "y" for years, "m" for months, "w" for weeks, and "d" for days. For example, "+1m +7d" represents one month and seven days from today.

I got the same error and when I unknowingly removed all the default pages of the DefaultAppPool itself.

Resolution

I have clicked the DefaultAppPool and opened the Default Document. Then clicked on the Revert to Parent link on the Actions pane. The default documents have came again, and thus it solves the issue. I'm not sure this is the best way, but this one was the error which I have just met and hope to share with you. I hope this may help some one.

AJAX isn't for downloading files. Pop up a new window with the download link as its address, or do document.location = ....

from Google

An .axd file is a HTTP Handler file. There are two types of .axd files.

1. ScriptResource.axd
2. WebResource.axd

These are files which are generated at runtime whenever you use ScriptManager in your Web app. This is being generated only once when you deploy it on the server.

Simply put the ScriptResource.AXD contains all of the clientside javascript routines for Ajax. Just because you include a scriptmanager that loads a script file it will never appear as a ScriptResource.AXD - instead it will be merely passed as the .js file you send if you reference a external script file. If you embed it in code then it may merely appear as part of the html as a tag and code but depending if you code according to how the ToolKit handles it - may or may not appear as as a ScriptResource.axd. ScriptResource.axd is only introduced with AJAX and you will never see it elsewhere

And ofcourse it is necessary

I had this problem because I configured my WCF Service to return a System.Data.DataTable.

It worked fine in my test HTML page, but blew up when I put this in my Windows Form application.

I had to go in and change the Service's Operational Contract signature from DataTable to DataSet and return the data accordingly.

If you have this problem, you may want to add an additional Operational Contract to your Service so you do not have to worry about breaking code that rely on existing Services.

I have written code that sniffs IE4 or greater and is currently functioning perfectly in sites for my company's clients, as well as my own personal sites.

Include the following enumerated constant and function variables into a javascript include file on your page...

//methods
var BrowserTypes = {
    Unknown: 0,
    FireFox: 1,
    Chrome: 2,
    Safari: 3,
    IE: 4,
    IE7: 5,
    IE8: 6,
    IE9: 7,
    IE10: 8,
    IE11: 8,
    IE12: 8
};

var Browser = function () {
    try {
        //declares
        var type;
        var version;
        var sVersion;

        //process
        switch (navigator.appName.toLowerCase()) {
            case "microsoft internet explorer":
                type = BrowserTypes.IE;
                sVersion = navigator.appVersion.substring(navigator.appVersion.indexOf('MSIE') + 5, navigator.appVersion.length);
                version = parseFloat(sVersion.split(";")[0]);
                switch (parseInt(version)) {
                    case 7:
                        type = BrowserTypes.IE7;
                        break;
                    case 8:
                        type = BrowserTypes.IE8;
                        break;
                    case 9:
                        type = BrowserTypes.IE9;
                        break;
                    case 10:
                        type = BrowserTypes.IE10;
                        break;
                    case 11:
                        type = BrowserTypes.IE11;
                        break;
                    case 12:
                        type = BrowserTypes.IE12;
                        break;
                }
                break;
            case "netscape":
                if (navigator.userAgent.toLowerCase().indexOf("chrome") > -1) { type = BrowserTypes.Chrome; }
                else { if (navigator.userAgent.toLowerCase().indexOf("firefox") > -1) { type = BrowserTypes.FireFox } };
                break;
            default:
                type = BrowserTypes.Unknown;
                break;
        }

        //returns
        return type;
    } catch (ex) {
    }
};

Then all you have to do is use any conditional functionality such as...

ie. value = (Browser() >= BrowserTypes.IE) ? node.text : node.textContent;

or WindowWidth = (((Browser() >= BrowserTypes.IE9) || (Browser() < BrowserTypes.IE)) ? window.innerWidth : document.documentElement.clientWidth);

or sJSON = (Browser() >= BrowserTypes.IE) ? xmlElement.text : xmlElement.textContent;

Get the idea? Hope this helps.

Oh, you might want to keep it in mind to QA the Browser() function after IE10 is released, just to verify they didn't change the rules.

The solution suggested

<system.webServer>
  <modules runAllManagedModulesForAllRequests="true" >
    <remove name="UrlRoutingModule"/>    
  </modules>
</system.webServer>

works, but can degrade performance and can even cause errors, because now all registered HTTP modules run on every request, not just managed requests (e.g. .aspx). This means modules will run on every .jpg .gif .css .html .pdf etc.

A more sensible solution is to include this in your web.config:

<system.webServer>
  <modules>
    <remove name="UrlRoutingModule-4.0" />
    <add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />
  </modules>
</system.webServer>

I'll throw jsTree into the ring, too. I've found it fairly adaptable to your particular situation. It's packed as a jQuery plugin.

It can run from a variety of data sources, but my favorite is a simple nested list, as described by @joe_coolish or here:

<ul>
  <li>
    Item 1
    <ul>
      <li>Item 1.1</li>
      ...
    </ul>
  </li>
  ...
</ul>

This structure fails gracefully into a static tree when JS is not available in the client, and is easy enough to read and understand from a coding perspective.

You need to make the changes in the binding configuration (in the app.config file) on the SERVER and the CLIENT, or it will not take effect.

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding maxReceivedMessageSize="2147483647 " max...=... />
        </basicHttpBinding>
       </bindings>
</system.serviceModel>

I tried all the suggestions above, but what worked in the end was changing the Application Pool managed pipeline from Integrated mode to Classic mode.
It runs in its own application pool - but it was the first .NET 4.0 service - all other servicves are on .NET 2.0 using Integrated pipeline mode. Its just a standard WCF service using is https - but on Server 2008 (not R2) - using IIS 7 (not 7.5) .

This is a simple example of what I used for a recent test. You need to make sure that your security settings are the same on the server and client.

var myBinding = new BasicHttpBinding();
myBinding.Security.Mode = BasicHttpSecurityMode.None;
var myEndpointAddress = new EndpointAddress("http://servername:8732/TestService/");
client = new ClientTest(myBinding, myEndpointAddress);
client.someCall();

tree -L 2 -u -g -p -d

Prints the directory tree in a pretty format up to depth 2 (-L 2). Print user (-u) and group (-g) and permissions (-p). Print only directories (-d). tree has a lot of other useful options.

Make sure to learn from the padding oracle asp.net vulnerability that just happened (you applied the patch, right? ...) and use protected sections to encrypt the machine key and any other sensitive configuration.

An alternative option is to set it in the machine level web.config, so its not even in the web site folder.

To generate it do it just like the linked article in David's answer.

i used chardet to detect possible encoding of this data ( if its text ), but get {'confidence': 0.0, 'encoding': None}. Then i tried to use pickle.load and get nothing again. I tried to save this as file , test many different formats and failed here too. Maybe you tell us what type have this 16512 bytes of mysterious data?

A simple way is to implement ajaxError:

Whenever an Ajax request completes with an error, jQuery triggers the ajaxError event. Any and all handlers that have been registered with the .ajaxError() method are executed at this time.

For example:

$('.log').ajaxError(function() {
  $(this).text('Triggered ajaxError handler.');
});

I would suggest reading the ajaxError documentation. It does more than the simple use-case demonstrated above - mainly its callback accepts a number of parameters:

$('.log').ajaxError(function(e, xhr, settings, exception) {
  if (settings.url == 'ajax/missing.html') {
    $(this).text('Triggered ajaxError handler.');
  }
});

If you already have a table and can't/don't want to recreate it for whatever reason, use indexes:

CREATE UNIQUE INDEX my_index ON my_table(col_1, col_2);

This issue was even more strange for us. Everything worked if you had previously visited the sharepoint site from the browser, before you made the SOAP call. However, if you did the SOAP call first we'd throw the above error.

We were able to resolve this issue by installing the sharepoint certificate on the client and adding the domain to the local intranet sites.

This line looks questionable:

page_output.innerHTML = str_output;

You can use .innerHTML within jQuery, or you can use it without, but you have to address the selector semantically one way or the other:

$('#page_output').innerHTML /* for jQuery */
document.getElementByID('page_output').innerHTML /* for standard JS */

or better yet

$('#page_output').html(str_output);

Your examples, I think, answer the question very well. The first function can be done as a single select, and is a good reason to use the inline style. The second could probably be done as a single statement (using a sub-query to get the max date), but some coders may find it easier to read or more natural to do it in multiple statements as you have done. Some functions just plain can't get done in one statement, and so require the multi-statement version.

I suggest using the simplest (inline) whenever possible, and using multi-statements when necessary (obviously) or when personal preference/readability makes it wirth the extra typing.

Use

var rootObject =  JsonConvert.DeserializeObject<RootObject>(string json);

Create your classes on JSON 2 C#

Json.NET documentation: Serializing and Deserializing JSON with Json.NET

I experienced the same issue, and found out that the applicationdeployed was of .NET version 3.5, but the Application pool was using .NET 2.0. That caused the problem you described above. Hope it helps someone.

I had the same issue in Windows 7.

The solution was to go to basic settings > connect as > specific user - and log in as a user, instead of the default 'pass-through'

This fixed the issue for me.

$("#datePicker").datePicker({startDate: new Date() });. This works for me

The best way is to change any setting you want in your code.

Check out the below example:

using(WCFServiceClient client = new WCFServiceClient ())
{ 
    client.Endpoint.Binding.SendTimeout = new TimeSpan(0, 1, 30);
}

I was getting this error due to the BasicHttpBinding not sending a compatible messageVersion to the service i was calling. My solution was to use a custom binding like below

 <bindings>
  <customBinding>
    <binding name="Soap11UserNameOverTransport" openTimeout="00:01:00" receiveTimeout="00:1:00" >
      <security authenticationMode="UserNameOverTransport">
      </security>          
      <textMessageEncoding messageVersion="Soap11WSAddressing10" writeEncoding="utf-8" />
      <httpsTransport></httpsTransport>
    </binding>
  </customBinding>      
</bindings>

I have a similar issue, have you tried:

proxy.ClientCredentials.Windows.AllowedImpersonationLevel =   
          System.Security.Principal.TokenImpersonationLevel.Impersonation;

Just want to point out

Apart from MaxRecivedMessageSize, there are also attributes under ReaderQuotas, you might hit number of items limit instead of size limit. MSDN link is here

We use log4net on our web applications.

It's ability to customize logging at run-time by changing the XML configuration file is very handy when an application is malfunctioning at run-time and you need to see more information.

It also allows you to target specific classes or attributes to log under. This is very handy when you have an idea where the error is occurring. A classic example is NHibernate where you want to see just the SQL going to the database.

Edit:

We write all events to a database and the Trace system. The event log we use for errors or exceptions. We log most events to a database so that we can create custom reports and let the users view the log if they want to right from the application.

What about -mmin?

find /var/www/html/audio -daystart -maxdepth 1 -mmin +59 -type f -name "*.mp3" \
    -exec rm -f {} \;

From man find:

-mmin n
        File's data was last modified n minutes ago.

Also, make sure to test this first!

... -exec echo rm -f '{}' \;
          ^^^^ Add the 'echo' so you just see the commands that are going to get
               run instead of actual trying them first.

I was using webHttpBinding and forgot to dicate the security mode of "Transport" on the binding configuration which caused the error:

  <webHttpBinding>
    <binding name="MyWCFServiceEndpoint">
      <security mode="Transport" />
    </binding>
  </webHttpBinding>

Adding this in configuration fixed the problem.

As Kaboing mentioned, MAXDOP(n) actually controls the number of CPU cores that are being used in the query processor.

On a completely idle system, SQL Server will attempt to pull the tables into memory as quickly as possible and join between them in memory. It could be that, in your case, it's best to do this with a single CPU. This might have the same effect as using OPTION (FORCE ORDER) which forces the query optimizer to use the order of joins that you have specified. IN some cases, I have seen OPTION (FORCE PLAN) reduce a query from 26 seconds to 1 second of execution time.

Books Online goes on to say that possible values for MAXDOP are:

0 - Uses the actual number of available CPUs depending on the current system workload. This is the default value and recommended setting.

1 - Suppresses parallel plan generation. The operation will be executed serially.

2-64 - Limits the number of processors to the specified value. Fewer processors may be used depending on the current workload. If a value larger than the number of available CPUs is specified, the actual number of available CPUs is used.

I'm not sure what the best usage of MAXDOP is, however I would take a guess and say that if you have a table with 8 partitions on it, you would want to specify MAXDOP(8) due to I/O limitations, but I could be wrong.

Here are a few quick links I found about MAXDOP:

Books Online: Degree of Parallelism

General guidelines to use to configure the MAXDOP option

I was using telerik and had exactly same problem.

adding this to web.config resolved my issue :)

<location path="Telerik.Web.UI.WebResource.axd">   
   <system.web>  
     <authorization>  
       <allow users="*"/>  
     </authorization>  
   </system.web>  
</location>

maybe it will help you too. it was Authentication problem.

In my case, I used an ordinary seekBar and just flipped out the layout.

seekbark_layout.xml - my layout that containts seekbar which we need to make vertical.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/rootView"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<SeekBar
    android:id="@+id/seekBar"
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:layout_alignParentBottom="true"/>

</RelativeLayout>

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.vgfit.seekbarexample.MainActivity">

<View
    android:id="@+id/headerView"
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:background="@color/colorAccent"/>

<View
    android:id="@+id/bottomView"
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:layout_alignParentBottom="true"
    android:background="@color/colorAccent"/>

<include
    layout="@layout/seekbar_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_above="@id/bottomView"
    android:layout_below="@id/headerView"/>

 </RelativeLayout>

And in MainActivity I rotate seekbar_layout:

import android.os.Bundle
import android.support.v7.app.AppCompatActivity
import android.widget.RelativeLayout
import kotlinx.android.synthetic.main.seekbar_layout.*


class MainActivity : AppCompatActivity() {

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    rootView.post {
        val w = rootView.width
        val h = rootView.height

        rootView.rotation = 270.0f
        rootView.translationX = ((w - h) / 2).toFloat()
        rootView.translationY = ((h - w) / 2).toFloat()

        val lp = rootView.layoutParams as RelativeLayout.LayoutParams
        lp.height = w
        lp.width = h
        rootView.requestLayout()
    }
}
}

As a result we have necessary vertical seekbar:

if you user $criteria, I recommend blow usage:

$criteria = new CDbCriteria();
$criteria->compare('email_id', 101);
$comments = EmailArchive::model()->findAll($criteria);

you can see this also in sockets ...

PrintWriter out = new PrintWriter(socket.getOutputStream());

out.println("hello");

Add a @JsonProperty annotated getter, which returns a String, for the favoriteNumber field:

public class Person {
    public String name;
    public int age;
    private int favoriteNumber;

    public Person(String name, int age, int favoriteNumber) {
        this.name = name;
        this.age = age;
        this.favoriteNumber = favoriteNumber;
    }

    @JsonProperty
    public String getFavoriteNumber() {
        return String.valueOf(favoriteNumber);
    }

    public static void main(String... args) throws Exception {
        Person p = new Person("Joe", 25, 123);
        ObjectMapper mapper = new ObjectMapper();
        System.out.println(mapper.writeValueAsString(p)); 
        // {"name":"Joe","age":25,"favoriteNumber":"123"}
    }
}

I happened to walk across this question looking for something similar. It gave me enough info to run a test to get the answer I wanted. So if anyone else wants to know how to dynamically add to or lookup a {key: 'value'} pair in a JavaScript object, this test should tell you all you might need to know.

var dictionary = {initialkey: 'initialValue'};
var key = 'something';
var key2 =  'somethingElse';
var value = 'value1';
var value2 = 'value2';
var keyInitial = 'initialkey';

console.log(dictionary[keyInitial]);

dictionary[key] =value;
dictionary[key2] = value2;
console.log(dictionary);

output

initialValue
{ initialkey: 'initialValue',
  something: 'value1',
  somethingElse: 'value2' }

Using the BaseName in Get-ChildItem displays the name of the file and and using Name displays the file name with the extension.

$filepath = Get-ChildItem "E:\Test\Basic-English-Grammar-1.pdf"

$filepath.BaseName

Basic-English-Grammar-1

$filepath.Name

Basic-English-Grammar-1.pdf

I had similar problem before. But this was resolved when I started using hostname instead of IP address in my connection string.

You can try

echo implode(', ', (array)$ret);

hi friend in this case you can use the

AppendDataBound="true"

and after this use the list item. for e.g.:

<asp:DropDownList ID="DropDownList1" runat="server" AppendDataBoundItems="true">
    <asp:ListItem Text="--Select One--" Value="" />   
</asp:DropDownList>

but the problem in this is after second time select data are append with old data.

The only way to do this is to iterate over the array. Obviously if you are sure that the results are ordered by id you can do a binary search

This is my sample code for load static variable

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class OnelinkConfig {
    public static int MODULE_CODE;
    public static int DEFAULT_PAGE;
    public static int DEFAULT_SIZE;

    @Autowired
    public void loadOnelinkConfig(@Value("${onelink.config.exception.module.code}") int code,
            @Value("${onelink.config.default.page}") int page, @Value("${onelink.config.default.size}") int size) {
        MODULE_CODE = code;
        DEFAULT_PAGE = page;
        DEFAULT_SIZE = size;
    }
}

Probably is APC related.

For the people having this problem, please specify you .ini settings. Specifically your apc.mmap_file_mask setting.

For file-backed mmap, it should be set to something like:

apc.mmap_file_mask=/tmp/apc.XXXXXX

To mmap directly from /dev/zero, use:

apc.mmap_file_mask=/dev/zero

For POSIX-compliant shared-memory-backed mmap, use:

apc.mmap_file_mask=/apc.shm.XXXXXX

You can try:

top -bn1 | grep "Cpu(s)" | \
           sed "s/.*, *\([0-9.]*\)%* id.*/\1/" | \
           awk '{print 100 - $1"%"}'

Lazy setting decides whether to load child objects while loading the Parent Object.You need to do this setting respective hibernate mapping file of the parent class.Lazy = true (means not to load child)By default the lazy loading of the child objects is true.

I hate when sites complicate download so much and use hacks instead of a good old link.

Dead simple version:

<a href="file.zip">Start automatic download!</a>

It works! In every browser!

If you want to download a file that is usually displayed inline (such as an image) then HTML5 has a download attribute that forces download of the file. It also allows you to override filename (although there is a better way to do it):

<a href="report-generator.php" download="result.xls">Download</a>

Version with a "thanks" page:

If you want to display "thanks" after download, then use:

<a href="file.zip" 
   onclick="if (event.button==0) 
     setTimeout(function(){document.body.innerHTML='thanks!'},500)">
 Start automatic download!
</a>

Function in that setTimeout might be more advanced and e.g. download full page via AJAX (but don't navigate away from the page — don't touch window.location or activate other links).

The point is that link to download is real, can be copied, dragged, intercepted by download accelerators, gets :visited color, doesn't re-download if page is left open after browser restart, etc.

That's what I use for ImageOptim

1. RestTemplate timeout with SimpleClientHttpRequestFactory To programmatically override the timeout properties, we can customize the SimpleClientHttpRequestFactory class as below.

Override timeout with SimpleClientHttpRequestFactory

//Create resttemplate
RestTemplate restTemplate = new RestTemplate(getClientHttpRequestFactory());

//Override timeouts in request factory
private SimpleClientHttpRequestFactory getClientHttpRequestFactory() 
{
    SimpleClientHttpRequestFactory clientHttpRequestFactory
                      = new SimpleClientHttpRequestFactory();
    //Connect timeout
    clientHttpRequestFactory.setConnectTimeout(10_000);

    //Read timeout
    clientHttpRequestFactory.setReadTimeout(10_000);
    return clientHttpRequestFactory;
}

2. RestTemplate timeout with HttpComponentsClientHttpRequestFactory SimpleClientHttpRequestFactory helps in setting timeout but it is very limited in functionality and may not prove sufficient in realtime applications. In production code, we may want to use HttpComponentsClientHttpRequestFactory which support HTTP Client library along with resttemplate.

HTTPClient provides other useful features such as connection pool, idle connection management etc.

Override timeout with HttpComponentsClientHttpRequestFactory

//Create resttemplate
RestTemplate restTemplate = new RestTemplate(getClientHttpRequestFactory());

//Override timeouts in request factory
private SimpleClientHttpRequestFactory getClientHttpRequestFactory() 
{
    HttpComponentsClientHttpRequestFactory clientHttpRequestFactory
                      = new HttpComponentsClientHttpRequestFactory();
    //Connect timeout
    clientHttpRequestFactory.setConnectTimeout(10_000);

    //Read timeout
    clientHttpRequestFactory.setReadTimeout(10_000);
    return clientHttpRequestFactory;
}

You can make the output just 4 and 24 using unlist:

unlist(gregexpr(pattern ='2',"the2quickbrownfoxeswere2tired"))
[1]  4 24

I think [ ]{4} might work in the example where you need to detect 4 spaces. Same with the rest: [ ]{1}, [ ]{2} and [ ]{3}. If you want to detect an empty string in general, ^[ ]*$ will do.

If you set unique parameters, then the cache does not work, for example:

$.ajax({
    url : "my_url",
    data : {
        'uniq_param' : (new Date()).getTime(),
        //other data
    }});

Add bottom:100% to your #menu:hover ul li:hover ul rule

Demo 1

#menu:hover ul li:hover ul {
    position: absolute;
    margin-top: 1px;
    font: 10px;
    bottom: 100%; /* added this attribute */
}

Or better yet to prevent the submenus from having the same effect, just add this rule

Demo 2

#menu>ul>li:hover>ul { 
    bottom:100%;
}

Demo 3

source: http://jsfiddle.net/W5FWW/4/

And to get back the border you can add the following attribute

#menu>ul>li:hover>ul { 
    bottom:100%;
    border-bottom: 1px solid transparent
}

You are very close. You applied the round to the series of values given by df.value1. The return type is thus a Series. You need to assign that series back to the dataframe (or another dataframe with the same Index).

Also, there is a pandas.Series.round method which is basically a short hand for pandas.Series.apply(np.round).

In[2]: 
    df.value1 = df.value1.round()
    print df

Out[2]:
    item  value1  value2
    0    a       1     1.3
    1    a       2     2.5
    2    a       0     0.0
    3    b       3    -1.0
    4    b       5    -1.0

playersList.get(0)

Java has limited operator polymorphism. So you use the get() method on List objects, not the array index operator ([])

If the method of this code is not static, you can get a work-around in 5.2 by using get_class($this).

class A {
    public function create1() {
        $class = get_class($this);
        return new $class();
    }
    public function create2() {
        return new static();
    }
}

class B extends A {

}

$b = new B();
var_dump(get_class($b->create1()), get_class($b->create2()));

The results:

string(1) "B"
string(1) "B"

Example for OUT : Variable gets value initialized after going into the method. Later the same value is returned to the main method.

namespace outreftry
{
    class outref
    {
        static void Main(string[] args)
        {
            yyy a = new yyy(); ;

            // u can try giving int i=100 but is useless as that value is not passed into
            // the method. Only variable goes into the method and gets changed its
            // value and comes out. 
            int i; 

            a.abc(out i);

            System.Console.WriteLine(i);
        }
    }
    class yyy
    {

        public void abc(out int i)
        {

            i = 10;

        }

    }
}

Output:

10

===============================================

Example for Ref : Variable should be initialized before going into the method. Later same value or modified value will be returned to the main method.

namespace outreftry
{
    class outref
    {
        static void Main(string[] args)
        {
            yyy a = new yyy(); ;

            int i = 0;

            a.abc(ref i);

            System.Console.WriteLine(i);
        }
    }
    class yyy
    {

        public void abc(ref int i)
        {
            System.Console.WriteLine(i);
            i = 10;

        }

    }
}

Output:

    0
    10

=================================

Hope its clear now.

May be:

ArrayList<ServiceModel> services = new ArrayList<>(parking.getServices());
intent.putExtra("servicios",services);

Answering the first two points:

• GPS will always give you a more precise location, if it is enabled and if there are no thick walls around.

• If location did not change, then you can call getLastKnownLocation(String) and retrieve the location immediately.

Using an alternative approach:

You can try getting the cell id in use or all the neighboring cells

TelephonyManager mTelephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
GsmCellLocation loc = (GsmCellLocation) mTelephonyManager.getCellLocation(); 
Log.d ("CID", Integer.toString(loc.getCid()));
Log.d ("LAC", Integer.toString(loc.getLac()));
// or 
List<NeighboringCellInfo> list = mTelephonyManager.getNeighboringCellInfo ();
for (NeighboringCellInfo cell : list) {
    Log.d ("CID", Integer.toString(cell.getCid()));
    Log.d ("LAC", Integer.toString(cell.getLac()));
}

You can refer then to cell location through several open databases (e.g., http://www.location-api.com/ or http://opencellid.org/ )

The strategy would be to read the list of tower IDs when reading the location. Then, in next query (10 minutes in your app), read them again. If at least some towers are the same, then it's safe to use getLastKnownLocation(String). If they're not, then wait for onLocationChanged(). This avoids the need of a third party database for the location. You can also try this approach.

Your bean or pojo class should implements parcelable interface.

For example:

public class BeanClass implements Parcelable{
    String name;
    int age;
    String sex;

    public BeanClass(String name, int age, String sex) {
        this.name = name;
        this.age = age;
        this.sex = sex;
    } 
     public static final Creator<BeanClass> CREATOR = new Creator<BeanClass>() {
        @Override
        public BeanClass createFromParcel(Parcel in) {
            return new BeanClass(in);
        }

        @Override
        public BeanClass[] newArray(int size) {
            return new BeanClass[size];
        }
    };
    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(name);
        dest.writeInt(age);
        dest.writeString(sex);
    }
}

Consider a scenario that you want to send the arraylist of beanclass type from Activity1 to Activity2.
Use the following code

Activity1:

ArrayList<BeanClass> list=new ArrayList<BeanClass>();

private ArrayList<BeanClass> getList() {
    for(int i=0;i<5;i++) {

        list.add(new BeanClass("xyz", 25, "M"));
    }
    return list;
}
private void gotoNextActivity() {
    Intent intent=new Intent(this,Activity2.class);
    /* Bundle args = new Bundle();
    args.putSerializable("ARRAYLIST",(Serializable)list);
    intent.putExtra("BUNDLE",args);*/

    Bundle bundle = new Bundle();
    bundle.putParcelableArrayList("StudentDetails", list);
    intent.putExtras(bundle);
    startActivity(intent);
}

Activity2:

ArrayList<BeanClass> listFromActivity1=new ArrayList<>();

listFromActivity1=this.getIntent().getExtras().getParcelableArrayList("StudentDetails");

if (listFromActivity1 != null) {

    Log.d("listis",""+listFromActivity1.toString());
}

I think this basic to understand the concept.

If you're trying to get data out of the request body, the code above works. But, I think you are having the same problem I was..

If the data in the body is in JSON form, and you want it as a Java object, you'll need to parse it yourself, or use a library like google-gson to handle it for you. You should look at the docs and examples at the project's website to know how to use it. It's fairly simple.

I guess things have changed in python 3.4. This worked for me:

print("resp:" + json.dumps(resp.json()))

@Baxter's is mostly correct but it is missing one important Windows-specific detail.

Subversion's runtime configuration area is stored in the %APPDATA%\Subversion\ directory. The files are config and servers.

However, in addition to text-based configuration files, Subversion clients can use Windows Registry to store the client settings. It makes it possible to modify the settings with PowerShell in a convenient manner, and also distribute these settings to user workstations in Active Directory environment via AD Group Policy. See SVNBook | Configuration and the Windows Registry (you can find examples and a sample *.reg file there).

You need two columns of the same type, one on each table, to JOIN on. Whether they're primary and foreign keys or not doesn't matter.

http://en.wikipedia.org/wiki/Division_by_zero

http://en.wikipedia.org/wiki/Unix_signal#SIGFPE

This should give you a really good idea. Since a modulus is, in its basic sense, division with a remainder, something % 0 IS division by zero and as such, will trigger a SIGFPE being thrown.

I saw one example that uses Import/Export-CLIXML.

These are my favorite commands for the issue you're trying to resolve. And the simplest way to use them is.

$passwordPath = './password.txt'
if (-not (test-path $passwordPath)) {
    $cred = Get-Credential -Username domain\username -message 'Please login.'
    Export-CliXML -InputObject $cred -Path $passwordPath
}
$cred = Import-CliXML -path $passwordPath

So if the file doesn't locally exist it will prompt for the credentials and store them. This will take a [pscredential] object without issue and will hide the credentials as a secure string.

Finally just use the credential like you normally do.

Restart-Computer -ComputerName ... -Credentail $cred

Note on Securty:

Securely store credentials on disk

When reading the Solution, you might at first be wary of storing a password on disk. While it is natural (and prudent) to be cautious of littering your hard drive with sensitive information, the Export-CliXml cmdlet encrypts credential objects using the Windows standard Data Protection API. This ensures that only your user account can properly decrypt its contents. Similarly, the ConvertFrom-SecureString cmdlet also encrypts the password you provide.

Edit: Just reread the original question. The above will work so long as you've initialized the [pscredential] to the hard disk. That is if you drop that in your script and run the script once it will create that file and then running the script unattended will be simple.

Deep copy involves using the contents of one object to create another instance of the same class. In a deep copy, the two objects may contain ht same information but the target object will have its own buffers and resources. the destruction of either object will not affect the remaining object. The overloaded assignment operator would create a deep copy of objects.

Shallow copy involves copying the contents of one object into another instance of the same class thus creating a mirror image. Owing to straight copying of references and pointers, the two objects will share the same externally contained contents of the other object to be unpredictable.

Explanation:

Using a copy constructor we simply copy the data values member by member. This method of copying is called shallow copy. If the object is a simple class, comprised of built in types and no pointers this would be acceptable. This function would use the values and the objects and its behavior would not be altered with a shallow copy, only the addresses of pointers that are members are copied and not the value the address is pointing to. The data values of the object would then be inadvertently altered by the function. When the function goes out of scope, the copy of the object with all its data is popped off the stack.

If the object has any pointers a deep copy needs to be executed. With the deep copy of an object, memory is allocated for the object in free store and the elements pointed to are copied. A deep copy is used for objects that are returned from a function.

Another simple way:

Dir.mkdir('tmp/excel') unless Dir.exist?('tmp/excel')

When you do a push, git only takes the changes that you have committed.

Remember when you do a git status it shows you the files you changed since the last push?

Once you commit those changes and do a push they are the only files that get pushed so you don't have to worry about thinking that the entire master gets pushed because in reality it does not.

How to push a single file:

git commit yourfile.js
git status
git push origin master

I usually use set_time_limit(30) within the main loop (so each loop iteration is limited to 30 seconds rather than the whole script).

I do this in multiple database update scripts, which routinely take several minutes to complete but less than a second for each iteration - keeping the 30 second limit means the script won't get stuck in an infinite loop if I am stupid enough to create one.

I must admit that my choice of 30 seconds for the limit is somewhat arbitrary - my scripts could actually get away with 2 seconds instead, but I feel more comfortable with 30 seconds given the actual application - of course you could use whatever value you feel is suitable.

Hope this helps!

With VS 2017, debugging ASP.NET project with Chrome doesn't sign you in with your Google account.

To fix that go to Tools -> Options -> Debugging -> General and turn off the setting Enable JavaScript Debugging for ASP.NET (Chrome and IE).

The original question asked for the exponent and mantissa, rather than the fractional and whole part.

To get the exponent and mantissa from a double you can convert it into the IEEE 754 representation and extract the bits like this:

long bits = Double.doubleToLongBits(3.25);

boolean isNegative = (bits & 0x8000000000000000L) != 0; 
long exponent      = (bits & 0x7ff0000000000000L) >> 52;
long mantissa      =  bits & 0x000fffffffffffffL;

Try adding System.Web as a reference to your project.

For Kotlin users:

override fun onCreateView(
    inflater: LayoutInflater,
    container: ViewGroup?, 
    savedInstanceState: Bundle?) : View?
{
    // Inflate the layout for this fragment
    var myView = inflater.inflate(R.layout.fragment_home, container, false)
    var btn_test = myView.btn_test as Button
    btn_test.setOnClickListener {
        textView.text = "hunny home fragment"
    }

    return myView
}

The Google Plugin for Eclipse depends on other specific Eclipse components, such as WST. Your installation of Eclipse may not yet include all of them, but they can be easily installed by following these instructions. Eclipse 3.7 (Indigo)

 Select Help > Install New Software...

Click the link for Available Software Sites.
Ensure there is an update site named Indigo. 

If this is not present, click Add... and 
enter http://download.eclipse.org/releases/indigo for the Location.

Now go through the installation steps; Eclipse should download and install 
the plugin's dependencies.

Going back to Servlet days, web.xml can have only one <context-param>, so only one context object gets created when server loads an application and the data in that context is shared among all resources (Ex: Servlets and JSPs). It is same as having Database driver name in the context, which will not change. In similar way, when we declare contextConfigLocation param in <contex-param> Spring creates one Application Context object.

 <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>com.myApp.ApplicationContext</param-value>
 </context-param>

You can have multiple Servlets in an application. For example you might want to handle /secure/* requests in one way and /non-seucre/* in other way. For each of these Servlets you can have a context object, which is a WebApplicationContext.

<servlet>
    <servlet-name>SecureSpringDispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextClass</param-name>
        <param-value>com.myapp.secure.SecureContext</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>SecureSpringDispatcher</servlet-name>
    <url-pattern>/secure/*</url-pattern>
</servlet-mapping>
<servlet>
    <servlet-name>NonSecureSpringDispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextClass</param-name>
        <param-value>com.myapp.non-secure.NonSecureContext</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>NonSecureSpringDispatcher</servlet-name>
    <url-pattern>/non-secure/*</url-patten>

bash-script, which checks for merging errors

I had the problem, that a few pdf-merges produced some error messages. As it is quite a lot trial and error to find the corrupt pdfs, I wrote a script for it.

The following bash-script, merges all available pdfs in a folder one by one and gives a success status after each merge. Just copy it in the folder with the pdfs and execute from there.

    #!/bin/bash
    
    PDFOUT=_all_merged.pdf
    rm -f ${PDFOUT}
    
    for f in $(ls *.pdf)
    do
      printf "processing %-50s" "$f  ..."
      if [ -f "$PDFOUT" ]; then
        # https://stackoverflow.com/questions/8158584/ghostscript-to-merge-pdfs-compresses-the-result
        #  -dPDFSETTINGS=/prepress
        status=`gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile="${PDFOUT}.new" ${PDFOUT} "$f" 2> /dev/null`
        nChars=`echo -n "${status}" | wc -c`
        if [ $nChars -gt 0 ]
        then
          echo "gs ERROR"
        else
          echo "successfully"
        fi
        mv "${PDFOUT}.new" ${PDFOUT}
      else
        cp "$f" ${PDFOUT}
        echo "successfully"
      fi
    done

example output:

processing inp1.pdf  ...                                     successfully
processing inp2.pdf  ...                                     successfully

Saw this thread while looking for something else and I know it is super old, but I wanted to add my 2 cents.

NEVER USE VLOOKUP. It's one of the worst performing formulas in excel. Use index match instead. It even works without sorting data, unless you have a -1 or 1 in the end of the match formula (explained more below)

Here is a link with the appropriate formulas.

The Sheet 2 formula would be this: =IF(A2="","",INDEX(Sheet1!B:B,MATCH($A2,Sheet1!$A:$A,0)))

• IF(A2="","", means if A2 is blank, return a blank value
• INDEX(Sheet1!B:B, is saying INDEX B:B where B:B is the data you want to return. IE the name column.
• Match(A2, is saying to Match A2 which is the ID you want to return the Name for.
• Sheet1!A:A, is saying you want to match A2 to the ID column in the previous sheet
• ,0)) is specifying you want an exact value. 0 means return an exact match to A2, -1 means return smallest value greater than or equal to A2, 1 means return the largest value that is less than or equal to A2. Keep in mind -1 and 1 have to be sorted.

More information on the Index/Match formula

Other fun facts: $ means absolute in a formula. So if you specify $B$1 when filling a formula down or over keeps that same value. If you over $B1, the B remains the same across the formula, but if you fill down, the 1 increases with the row count. Likewise, if you used B$1, filling to the right will increment the B, but keep the reference of row 1.

I also included the use of indirect in the second section. What indirect does is allow you to use the text of another cell in a formula. Since I created a named range sheet1!A:A = ID, sheet1!B:B = Name, and sheet1!C:C=Price, I can use the column name to have the exact same formula, but it uses the column heading to change the search criteria.

Good luck! Hope this helps.

you can try this and don't need JQuery: timeSolver.js

For example, add 5 day on today:

var newDay = timeSolver.add(new Date(),5,"day");

You also can add by hour, month...etc. please see for more infomation.

DllImport will work fine without the complete path specified as long as the dll is located somewhere on the system path. You may be able to temporarily add the user's folder to the path.

To add something to this (cause I found it while searching on this problem, and my solution involved slightly more)...

If you don't have a "Browse with..." option for .aspx files (as I didn't in a MVC application), the easiest solution is to add a dummy HTML file, and right-click it to set the option as described in the answer. You can remove the file afterward.

The option is actually set in: C:\Documents and Settings[user]\Local Settings\Application Data\Microsoft\VisualStudio[version]\browser.xml

However, if you modify the file directly while VS is running, VS will overwrite it with your previous option on next run. Also, if you edit the default in VS you won't have to worry about getting the schema right, so the work-around dummy file is probably the easiest way.

Just to complete this topic: If you set up your table with primary key and auto increment you can omit the process of manually incrementing the id.

Check out this example

if (!$CI->db->table_exists(db_prefix() . 'my_table_name')) {
    $CI->db->query('CREATE TABLE `' . db_prefix() . "my_table_name` (
  `serviceid` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT,
  `name` varchar(64) NOT NULL,
  `hash` varchar(32) NOT NULL,
  `url` varchar(120) NOT NULL,
  `datecreated` datetime NOT NULL,
  `active` tinyint(1) NOT NULL DEFAULT '1'
) ENGINE=InnoDB DEFAULT CHARSET=" . $CI->db->char_set . ';');

Now you can insert rows

$this->db->insert(db_prefix(). 'my_table_name', [
            'name'         => $data['name'],
            'hash'            => app_generate_hash(),
            'url'     => $data['url'],
            'datecreated'     => date('Y-m-d H:i:s'),
            'active'          => $data['active']
        ]);

2^8 = 256 Characters. A character in binary is a series of 8 ( 0 or 1).

SELECT DATEDIFF(hh, firstDate, secondDate) FROM tableName WHERE ...

Use char for 16 bit unsigned integers.

You can not do that...

via css the URL you put on the background-image is just for the image.

Via HTML you have to add the href for your hyperlink in this way:

<a href="http://home.com" id="logo">Your logo</a>

With text-indent and some other css you can adjust your a element to show just the image and clicking on it you will go to your link.

EDIT:

I'm here again to show you and explain why my solution is much better:

<a href="http://home.com" id="logo">Your logo name</a>

This block of HTML is SEO friendly because you have some text inside your link!

How to style it with css:

#logo {
  background-image: url(images/logo.png);
  display: block;
  margin: 0 auto;
  text-indent: -9999px;
  width: 981px;
  height: 180px;
}

Then if you don't care about SEO good to choose the other answer.

• Full days between end of month and start of today, including the last day of the month:

  SELECT LAST_DAY (TRUNC(SysDate)) - TRUNC(SysDate) + 1 FROM dual
  

• Days between using exact time:

  SELECT SysDate - TO_DATE('2018-01-01','YYYY-MM-DD') FROM dual
  

You can use the adjacent sibling selector to achieve something similar, that might help.

.list-item.other-class + .list-item:not(.other-class)

Will effectively target the immediately following element after the last element with the class other-class.

Open your terminal and type: Android_Sdk_Path/tools

Run ./monitor

The problem happens when a floated element is within a container box, that element does not automatically force the container’s height adjust to the floated element. When an element is floated, its parent no longer contains it because the float is removed from the flow. You can use 2 methods to fix it:

• { clear: both; }
• clearfix

Once you understand what is happening, use the method below to “clearfix” it.

.clearfix:after {
    content: ".";
    display: block;
    clear: both;
    visibility: hidden;
    line-height: 0;
    height: 0;
}

.clearfix {
    display: inline-block;
}

html[xmlns] .clearfix {
    display: block;
}

* html .clearfix {
    height: 1%;
}

Demonstration :)

for your example:

{'profiles': [{'name':'john', 'age': 44}, {'name':'Alex','age':11}]}

you will have to do something of this effect:

JSONObject myjson = new JSONObject(the_json);
JSONArray the_json_array = myjson.getJSONArray("profiles");

this returns the array object.

Then iterating will be as follows:

    int size = the_json_array.length();
    ArrayList<JSONObject> arrays = new ArrayList<JSONObject>();
    for (int i = 0; i < size; i++) {
        JSONObject another_json_object = the_json_array.getJSONObject(i);
            //Blah blah blah...
            arrays.add(another_json_object);
    }

//Finally
JSONObject[] jsons = new JSONObject[arrays.size()];
arrays.toArray(jsons);

//The end...

You will have to determine if the data is an array (simply checking that charAt(0) starts with [ character).

Hope this helps.

As the cause of the error is obvious, here's some information that should help you solve the problem:

See this MS article about Naming Files, Paths, and Namespaces

Here's a quote from the link:

Maximum Path Length Limitation In the Windows API (with some exceptions discussed in the following paragraphs), the maximum length for a path is MAX_PATH, which is defined as 260 characters. A local path is structured in the following order: drive letter, colon, backslash, name components separated by backslashes, and a terminating null character. For example, the maximum path on drive D is "D:\some 256-character path string<NUL>" where "<NUL>" represents the invisible terminating null character for the current system codepage. (The characters < > are used here for visual clarity and cannot be part of a valid path string.)

And a few workarounds (taken from the comments):

There are ways to solve the various problems. The basic idea of the solutions listed below is always the same: Reduce the path-length in order to have path-length + name-length < MAX_PATH. You may:

• Share a subfolder
• Use the commandline to assign a drive letter by means of SUBST
• Use AddConnection under VB to assign a drive letter to a path

You can use this code, this code is for AES-256-CBC or you can use it for other AES encryption. Key length error mainly comes in 256-bit encryption.

This error comes due to the encoding or charset name we pass in the SecretKeySpec. Suppose, in my case, I have a key length of 44, but I am not able to encrypt my text using this long key; Java throws me an error of invalid key length. Therefore I pass my key as a BASE64 in the function, and it converts my 44 length key in the 32 bytes, which is must for the 256-bit encryption.

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import java.security.MessageDigest;
import java.security.Security;
import java.util.Base64;

public class Encrypt {

    static byte [] arr = {1,2,3,4,5,6,7,8,9};

    // static byte [] arr = new byte[16];

      public static void main(String...args) {
        try {
         //   System.out.println(Cipher.getMaxAllowedKeyLength("AES"));
            Base64.Decoder decoder = Base64.getDecoder();
            // static byte [] arr = new byte[16];
            Security.setProperty("crypto.policy", "unlimited");
            String key = "Your key";
       //     System.out.println("-------" + key);

            String value = "Hey, i am adnan";
            String IV = "0123456789abcdef";
       //     System.out.println(value);
            // log.info(value);
          IvParameterSpec iv = new IvParameterSpec(IV.getBytes());
            //    IvParameterSpec iv = new IvParameterSpec(arr);

        //    System.out.println(key);
            SecretKeySpec skeySpec = new SecretKeySpec(decoder.decode(key), "AES");
         //   System.out.println(skeySpec);
            Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        //    System.out.println("ddddddddd"+IV);
            cipher.init(Cipher.ENCRYPT_MODE, skeySpec, iv);
       //     System.out.println(cipher.getIV());

            byte[] encrypted = cipher.doFinal(value.getBytes());
            String encryptedString = Base64.getEncoder().encodeToString(encrypted);

            System.out.println("encrypted string,,,,,,,,,,,,,,,,,,,: " + encryptedString);
            // vars.put("input-1",encryptedString);
            //  log.info("beanshell");
        }catch (Exception e){
            System.out.println(e.getMessage());
        }
    }
}

There is a misunderstanding here with respect to what a "fork" is. A fork is in fact nothing more than a set of per-user branches. When you push to a fork you actually do push to the original repository, because that is the ONLY repository.

You can try this out by pushing to a fork, noting the commit and then going to the original repository and using the commit ID, you'll see that the commit is "in" the original repository.

This makes a lot of sense, but it is far from obvious (I only discovered this accidentally recently).

When John forks repository SuperProject what seems to actually happen is that all branches in the source repository are replicated with a name like "John.master", "John.new_gui_project", etc.

GitHub "hides" the "John." from us and gives us the illusion we have our own "copy" of the repository on GitHub, but we don't and nor is one even needed.

So my fork's branch "master" is actually named "Korporal.master", but the GitHub UI never reveals this, showing me only "master".

This is pretty much what I think goes on under the hood anyway based on stuff I've been doing recently and when you ponder it, is very good design.

For this reason I think it would be very easy for Microsoft to implement Git forks in their Visual Studio Team Services offering.

Update

See my other SO answer.

Original

var request = (HttpWebRequest)WebRequest.Create("https://example.com/endpoint");

string stringData = ""; // place body here
var data = Encoding.Default.GetBytes(stringData); // note: choose appropriate encoding

request.Method = "PUT";
request.ContentType = ""; // place MIME type here
request.ContentLength = data.Length;

var newStream = request.GetRequestStream(); // get a ref to the request body so it can be modified
newStream.Write(data, 0, data.Length);
newStream.Close();

A few ways:

-- Do the comparison, OR'd with a check on the @Country=0 case
WHERE (a.Country = @Country OR @Country = 0)

-- compare the Country field to itself
WHERE a.Country = CASE WHEN @Country > 0 THEN @Country ELSE a.Country END

Or, use a dynamically generated statement and only add in the Country condition if appropriate. This should be most efficient in the sense that you only execute a query with the conditions that actually need to apply and can result in a better execution plan if supporting indices are in place. You would need to use parameterised SQL to prevent against SQL injection.

In PowerShell V2, @ is also the Splat operator.

PS> # First use it to create a hashtable of parameters:
PS> $params = @{path = "c:\temp"; Recurse= $true}
PS> # Then use it to SPLAT the parameters - which is to say to expand a hash table 
PS> # into a set of command line parameters.
PS> dir @params
PS> # That was the equivalent of:
PS> dir -Path c:\temp -Recurse:$true

The align-items, or respectively align-content attribute controls this behaviour.

align-items defines the items' positioning perpendicularly to flex-direction.

The default flex-direction is row, therfore vertical placement can be controlled with align-items.

There is also the align-self attribute to control the alignment on a per item basis.

#a {_x000D_
  display:flex;_x000D_
_x000D_
  align-items:flex-start;_x000D_
  align-content:flex-start;_x000D_
  }_x000D_
_x000D_
#a > div {_x000D_
  _x000D_
  background-color:red;_x000D_
  padding:5px;_x000D_
  margin:2px;_x000D_
  }_x000D_
 #a > #c {_x000D_
  align-self:stretch;_x000D_
 }

<div id="a">_x000D_
  _x000D_
  <div id="b">left</div>_x000D_
  <div id="c">middle</div>_x000D_
  <div>right<br>right<br>right<br>right<br>right<br></div>_x000D_
  _x000D_
</div>

css-tricks has an excellent article on the topic. I recommend reading it a couple of times.

Most likely, as mentioned by others, it is a class carrying the css values:

.clear{clear: both;} 

in order to prevent any more page elements from extending into the footer element. It is a quick and easy way of making sure that pages with columns of varying heights don't cause the footer to render oddly, by possibly setting its top position at the end of a shorter column.

In many cases it is not necessary, but if you are using best-practice standards it is a good idea to use, if you are floating page elements left and right. It functions with page elements similar to the way a horizontal rule works with text, to ensure proper and complete sepperation.

import java.text.DecimalFormat;

public class RoundTest {
    public static void main(String[] args) {
        double i = 2;    
        DecimalFormat twoDForm = new DecimalFormat("#.00");
        System.out.println(twoDForm.format(i));
        double j=3.1;
        System.out.println(twoDForm.format(j));
        double k=4.144456;
        System.out.println(twoDForm.format(k));
    }
}

You remove the original image here:

newImg.animate(css, SPEED, function() {
    img.remove();
    newImg.removeClass('morpher');
    (callback || function() {})();
});

And all that's left behind is newImg. Then you reset link references the image using #rocket:

$("#rocket").attr('src', ...

But your newImg doesn't have an id attribute let alone an id of rocket.

To fix this, you need to remove img and then set the id attribute of newImg to rocket:

newImg.animate(css, SPEED, function() {
    var old_id = img.attr('id');
    img.remove();
    newImg.attr('id', old_id);
    newImg.removeClass('morpher');
    (callback || function() {})();
});

And then you'll get the shiny black rocket back again: http://jsfiddle.net/ambiguous/W2K9D/

UPDATE: A better approach (as noted by mellamokb) would be to hide the original image and then show it again when you hit the reset button. First, change the reset action to something like this:

$("#resetlink").click(function(){
    clearInterval(timerRocket);
    $("#wrapper").css('top', '250px');
    $('.throbber, .morpher').remove(); // Clear out the new stuff.
    $("#rocket").show();               // Bring the original back.
});

And in the newImg.load function, grab the images original size:

var orig = {
    width: img.width(),
    height: img.height()
};

And finally, the callback for finishing the morphing animation becomes this:

newImg.animate(css, SPEED, function() {
    img.css(orig).hide();
    (callback || function() {})();
});

New and improved: http://jsfiddle.net/ambiguous/W2K9D/1/

The leaking of $('.throbber, .morpher') outside the plugin isn't the best thing ever but it isn't a big deal as long as it is documented.

You need to pass the labels to be dropped.

df.drop(df.index, inplace=True)

By default, it operates on axis=0.

You can achieve the same with

df.iloc[0:0]

which is much more efficient.

If you got factor then you could change levels by standard method:

df <- data.frame(name = c('cow','pig','eagle','pigeon'), 
             stringsAsFactors = FALSE)
df$type <- factor(df$name) # First step: copy vector and make it factor
# Change levels:
levels(df$type) <- list(
    animal = c("cow", "pig"),
    bird = c("eagle", "pigeon")
)
df
#     name   type
# 1    cow animal
# 2    pig animal
# 3  eagle   bird
# 4 pigeon   bird

You could write simple function as a wrapper:

changelevels <- function(f, ...) {
    f <- as.factor(f)
    levels(f) <- list(...)
    f
}

df <- data.frame(name = c('cow','pig','eagle','pigeon'), 
                 stringsAsFactors = TRUE)

df$type <- changelevels(df$name, animal=c("cow", "pig"), bird=c("eagle", "pigeon"))

Using ASP.NET's visible="false" property will set the visibility attribute where as I think when you call show() in jQuery it modifies the display attribute of the CSS style.

So doing the latter won't rectify the former.

You need to do this:

$("#test1").attr("visibility", "visible");

Check gradle console tab in android studio (by default in bottom right corner). In my case there were errors like this:

C:\Users\Jozef Bar??k\.gradle\caches\transforms-1\files-1.1\appcompat-v7-25.4.0.aar\d68bb9d2059935a7891196f4dfb81686\res\drawable-hdpi-v4\abc_ic_menu_share_mtrl_alpha.png: error: file not found.

Error: java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details
:app:mergeDebugResources FAILED

I solved the issue setting gradle user home to another location without white or special characters:

C:\Android\.gradle

You can configure it setting "Service directory path" in Gradle settings dialog. In my case it was necessary to delete old .gradle directory on previous location and restart android studio.

Bootstrap 3 introduces responsive tables:

<div class="table-responsive">
  <table class="table">
    ...
  </table>
</div>

Bootstrap 4 is similar, but with more control via some new classes:

...responsive across all viewports ... with .table-responsive. Or, pick a maximum breakpoint with which to have a responsive table up to by using .table-responsive{-sm|-md|-lg|-xl}.

This maybe too late but No one provided a clear explanation of how the algorithm works

The idea of Dijkstra is simple, let me show this with the following pseudocode.

Dijkstra partitions all nodes into two distinct sets. Unsettled and settled. Initially all nodes are in the unsettled set, e.g. they must be still evaluated.

At first only the source node is put in the set of settledNodes. A specific node will be moved to the settled set if the shortest path from the source to a particular node has been found.

The algorithm runs until the unsettledNodes set is empty. In each iteration it selects the node with the lowest distance to the source node out of the unsettledNodes set. E.g. It reads all edges which are outgoing from the source and evaluates each destination node from these edges which are not yet settled.

If the known distance from the source to this node can be reduced when the selected edge is used, the distance is updated and the node is added to the nodes which need evaluation.

Please note that Dijkstra also determines the pre-successor of each node on its way to the source. I left that out of the pseudo code to simplify it.

One more alternative options

var map = new google.maps.Map(document.getElementById('map_canvas'), {
    zoom: 1,
    center: new google.maps.LatLng(35.137879, -82.836914),
    mapTypeId: google.maps.MapTypeId.ROADMAP
});

var myMarker = new google.maps.Marker({
    position: new google.maps.LatLng(47.651968, 9.478485),
    draggable: true
});

google.maps.event.addListener(myMarker, 'dragend', function (evt) {
    document.getElementById('current').innerHTML = '<p>Marker dropped: Current Lat: ' + evt.latLng.lat().toFixed(3) + ' Current Lng: ' + evt.latLng.lng().toFixed(3) + '</p>';
});

google.maps.event.addListener(myMarker, 'dragstart', function (evt) {
    document.getElementById('current').innerHTML = '<p>Currently dragging marker...</p>';
});

map.setCenter(myMarker.position);
myMarker.setMap(map);

You can use it this way:

$root = 'C:'
$folder1 = 'Program Files (x86)'
$folder2 = 'Microsoft.NET'

if (-Not(Test-Path $(Join-Path $root -ChildPath $folder1 | Join-Path -ChildPath $folder2)))
{
   "Folder does not exist"
}
else 
{
   "Folder exist"
}

Found one solution for WIFI (works for Android 4.3, 4.4):

1. Connect to WIFI network (e.g. 'Alex')
2. Settings->WIFI
3. Long tap on connected network's name (e.g. on 'Alex')
4. Modify network config-> Show advanced options
5. Set proxy settings

This will get you the drives on the machine:

System.IO.DriveInfo.GetDrives()

These two methods will get you the bad characters to check:

System.IO.Path.GetInvalidFileNameChars();
System.IO.Path.GetInvalidPathChars();

I can recommend this in "bash -ue" mode:

set -ue
   
false && RET=$? || RET=$? 
echo "expecting 1, got ${RET}"
true && RET=$? || RET=$? 
echo "expecting 0, got ${RET}"

echo "test try...catch"
false && RET=$? || RET=$? 
if [ ${RET} -ne 0 ]; then
  echo "caught error ${RET}"
fi

echo "beware, using '||' before '&&' fails"
echo "  -> memory aid: [A]nd before [O]r in the alphabet"
false || RET=$? && RET=$? 
echo "expecting 1, got ${RET}"
true || RET=$? && RET=$? 
echo "expecting 0, got ${RET}"

The li tag has a property called list-style-position. This makes your bullets inside or outside the list. On default, it’s set to inside. That makes your text wrap around it. If you set it to outside, the text of your li tags will be aligned.

The downside of that is that your bullets won't be aligned with the text outside the ul. If you want to align it with the other text you can use a margin.

ul li {
    /*
     * We want the bullets outside of the list,
     * so the text is aligned. Now the actual bullet
     * is outside of the list’s container
     */
    list-style-position: outside;

    /*
     * Because the bullet is outside of the list’s
     * container, indent the list entirely
     */
    margin-left: 1em;
}

Edit 15th of March, 2014 Seeing people are still coming in from Google, I felt like the original answer could use some improvement

• Changed the code block to provide just the solution
• Changed the indentation unit to em’s
• Each property is applied to the ul element
• Good comments :)

This is an old post, but I'd like to object to some of the answers. If you're transferring sensitive data, you'll want to be using SSL. If you use SSL with a GET parameter (e.g. ?userid=123), that data will be sent in plain text! If you send using a POST, the values get put in the encrypted body of the message, and therefore are not readable to most MITM attacks.

The big distinction is where the data is passed. It only makes sense that if the data is placed in a URL, it CAN'T be encrypted otherwise you wouldn't be able to route to the server because only you could read the URL. That's how a GET works.

In short, you can securely transmit data in a POST over SSL, but you cannot do so with a GET, using SSL or not.

I can't set "UTF-8 with BOM" in the corner button either, but I can change it from the menu bar.

"File"->"Save with encoding"->"UTF-8 with BOM"

I won't get setSelection() method directly , so i done like below and work like charm

EditText editText = (EditText)findViewById(R.id.edittext_id);
editText.setText("Updated New Text");
int position = editText.getText().length();
Editable editObj= editText.getText();
Selection.setSelection(editObj, position);

This would do the work and avoid the issue that you can no longer select part of the text by mouse.

$("input[type=text]").click(function() {
    if(!$(this).hasClass("selected")) {
        $(this).select();
        $(this).addClass("selected");
    }
});
$("input[type=text]").blur(function() {
    if($(this).hasClass("selected")) {
        $(this).removeClass("selected");
    }
});

tl;dr for folks looking here for an ISO formatted date:

instead of using something like '%Y-%m-%d %H:%M:%S.%03d%z', create your own class as @unutbu indicated. Here's one for iso date format:

import logging
from time import gmtime, strftime

class ISOFormatter(logging.Formatter):
    def formatTime(self, record, datefmt=None):
        t = strftime("%Y-%m-%dT%H:%M:%S", gmtime(record.created))
        z = strftime("%z",gmtime(record.created))
        s = "%s.%03d%s" % (t, record.msecs,z)        
        return s

logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)

console = logging.StreamHandler()
logger.addHandler(console)

formatter = ISOFormatter(fmt='%(asctime)s - %(module)s - %(levelname)s - %(message)s')
console.setFormatter(formatter)

logger.debug('Jackdaws love my big sphinx of quartz.')
#2020-10-23T17:25:48.310-0800 - <stdin> - DEBUG - Jackdaws love my big sphinx of quartz.

Perhaps this is obvious, but FWIW this will only work if the web server is serving requests for that website on the alternate port. It's not at all uncommon for a webserver to only serve a site on port 80.

HTML4 specification states that:

Inline elements may contain only data and other inline elements

Span is an inline element, therefore having span inside span is valid. There's a related question: Can <span> tags have any type of tags inside them? which makes it completely clear.

HTML5 specification (including the most current draft of HTML 5.3 dated November 16, 2017) changes terminology, but it's still perfectly valid to place span inside another span.

I just add here something related. I was wanted to access a vector with backend indices, ie writting something like tail(x, i) but to return x[length(x) - i + 1] and not the whole tail.

Following commentaries I benchmarked two solutions:

accessRevTail <- function(x, n) {
    tail(x,n)[1]
}

accessRevLen <- function(x, n) {
  x[length(x) - n + 1]
}

microbenchmark::microbenchmark(accessRevLen(1:100, 87), accessRevTail(1:100, 87))
Unit: microseconds
                     expr    min      lq     mean median      uq     max neval
  accessRevLen(1:100, 87)  1.860  2.3775  2.84976  2.803  3.2740   6.755   100
 accessRevTail(1:100, 87) 22.214 23.5295 28.54027 25.112 28.4705 110.833   100

So it appears in this case that even for small vectors, tail is very slow comparing to direct access

Looks like your depth variable is unset. This means that the expression [ $depth -eq $zero ] becomes [ -eq 0 ] after bash substitutes the values of the variables into the expression. The problem here is that the -eq operator is incorrectly used as an operator with only one argument (the zero), but it requires two arguments. That is why you get the unary operator error message.

EDIT: As Doktor J mentioned in his comment to this answer, a safe way to avoid problems with unset variables in checks is to enclose the variables in "". See his comment for the explanation.

if [ "$depth" -eq "0" ]; then
   echo "false";
   exit;
fi

An unset variable used with the [ command appears empty to bash. You can verify this using the below tests which all evaluate to true because xyz is either empty or unset:

• if [ -z ] ; then echo "true"; else echo "false"; fi
• xyz=""; if [ -z "$xyz" ] ; then echo "true"; else echo "false"; fi
• unset xyz; if [ -z "$xyz" ] ; then echo "true"; else echo "false"; fi

You can use :

1. git stash to save your work
2. git checkout <your-branch>
3. git stash apply or git stash pop to load your last work

Git stash extremely useful when you want temporarily save undone or messy work, while you want to doing something on another branch.

git -stash documentation

I find until very useful with sleep. example:

> time = Time.now
> sleep 2.seconds until Time.now > time + 10.seconds # breaks when true
# or something like
> sleep 1.seconds until !req.loading # suggested by ohsully

See THIS previous SO post on using a variable on the replacement side of s///in Perl. Look both at the accepted answer and the rebuttal answer.

What you are trying to do is possible with the s///ee form that performs a double eval on the right hand string. See perlop quote like operators for more examples.

Be warned that there are security impilcations of evaland this will not work in taint mode.

Here is a simple one liner

var segment = (arr, n) => arr.reduce((r,e,i) => i%n ? (r[r.length-1].push(e), r)_x000D_
                                                    : (r.push([e]), r), []),_x000D_
        arr = Array.from({length: 31}).map((_,i) => i+1);_x000D_
console.log(segment(arr,7));

For future reference Python is strongly typed. Unlike other dynamic languages, it will not automagically cast objects from one type or the other (say from str to int) so you must do this yourself. You'll like that in the long-run, trust me!

Here's another way of doing it with a WHS script:

Set objWMIService = GetObject("Winmgmts:root\cimv2")

For Each objComputer in _
    objWMIService.InstancesOf("Win32_ComputerSystem")

    objComputer.rename "NewComputerName", NULL, NULL 
Next

Since it's now 2015, if you stumbled across this question then you should probably be using window.matchMedia (and, if it's still 2015, polyfilling for older browsers):

if (matchMedia('handheld').matches) {
    //...
} else {
    //...
}

Try this:

dict = {0:{1:'a'}, 1:{2:'b'}, 2:{3:'c'}}
for (var key in dict){
  console.log( key, dict[key] );
}

0 Object { 1="a"}
1 Object { 2="b"}
2 Object { 3="c"}

A possible very simple fix that worked for me. After deleting any database references and connections you find in server/serverobject explorer, right click the App_Data folder (didn't show any objects within the application for me) and select open. Once open put all the database/etc. files in a backup folder or if you have the guts just delete them. Run your application and it should recreate everything from scratch.

I am working in python flask: I had the same problem... There was a "," after I declared my my form variables; I am working with wtforms. That is what caused all the confusion

I had the same issue. turns out that Capitalizing the "A" in "App" was the issue. Also, if you do export: export default App; make sure you export the same name "App" as well.

First, put the app into the background (press the device's home button)

Then....in a terminal....

adb shell am kill com.your.package

I have used FileSaver.js to save the blob as file.

This is the repo : https://github.com/eligrey/FileSaver.js/

Usage:

import { saveAs } from 'file-saver';

var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
saveAs(blob, "hello world.txt");

saveAs("https://httpbin.org/image", "image.jpg");

To get the current time's milliseconds, use http://momentjs.com/docs/#/get-set/millisecond/

var timeInMilliseconds = moment().milliseconds();

Your answer is in wikipedia: modulo operation

It says, that in Java the sign on modulo operation is the same as that of dividend. and since we're talking about the rest of the division operation is just fine, that it returns -13 in your case, since -13/64 = 0. -13-0 = -13.

EDIT: Sorry, misunderstood your question...You're right, java should give -13. Can you provide more surrounding code?

Use -a (for and) and -o (for or) operations.

tldp.org/LDP/Bash-Beginners-Guide/html/sect_07_01.html

Update

Actually you could still use && and || with the -eq operation. So your script would be like this:

my_error_flag=1
my_error_flag_o=1
if [ $my_error_flag -eq 1 ] ||  [ $my_error_flag_o -eq 2 ] || ([ $my_error_flag -eq 1 ] && [ $my_error_flag_o -eq 2 ]); then
      echo "$my_error_flag"
else
    echo "no flag"
fi

Although in your case you can discard the last two expressions and just stick with one or operation like this:

my_error_flag=1
my_error_flag_o=1
if [ $my_error_flag -eq 1 ] ||  [ $my_error_flag_o -eq 2 ]; then
      echo "$my_error_flag"
else
    echo "no flag"
fi

var theName;

theName = $("input selector goes here").attr("name");

Here is the question: Is it possible that I can set the default value without using attribute 'value'?

Nope: value is the only way to set the default attribute.

Why don't you want to use it?

More generally.

byte[] buf = new byte[] { 123, 2, 233 };

string s = String.Concat(buf.Select(b => b.ToString("X2")));

I have done experimentation on this.

It's true that System.gc(); only suggests to run the Garbage Collector.

But calling System.gc(); after setting all references to null, will improve performance and memory occupation.

Concrete example

mosquitto.org is very active (at the time of this posting). This is a nice smoke test for a MQTT subscriber linux device:

mosquitto_sub -h test.mosquitto.org -t "#" -v

The "#" is a wildcard for topics and returns all messages (topics): the server had a lot of traffic, so it returned a 'firehose' of messages.

If your MQTT device publishes a topic of irisys/V4D-19230005/ to the test MQTT broker , then you could filter the messages:

mosquitto_sub -h test.mosquitto.org -t "irisys/V4D-19230005/#" -v

Options:

• -h the hostname (default MQTT port = 1883)
• -t precedes the topic

There is a similar question Extract main domain name from a given url. If you take a look at this answer , you will see that it is very easy. You just need to use java.net.URL and String utility - Split

The Mono project is your best option. However, it has a lot of pitfalls (like incomplete API support in some areas), and it's legally gray (people like Richard Stallman have derided the use of Mono because of the possibility of Microsoft coming down on Mono by using its patent rights, but that's another story).

Anyway, Apache supports .NET/Mono through a module, but the last time I checked the version supplied with Debian, it gave Perl language support only; I can't say if it's changed since, perhaps someone else can correct me there.

This might be a bit of a hack, but I avoided the issue and converted the json into PHP's POST array on the server side:

$_POST = json_decode(file_get_contents('php://input'), true);

I was having the same problems and believe I have solved it. I used the link meta tag as mentioned here to point to the image I wanted, but the key is that if you do that FB won't pull any other images as choices. Also if your image is too big, you won't have any choices at all.

Here's how I fixed my site http://gnorml.com/blog/facebook-link-thumbnails/

For those still looking for a simple answer, check out git cherry. It compares actual diffs instead of commit hashes. That means it accommodates commits that have been cherry picked or rebased.

First checkout the branch you want to delete:

git checkout [branch-to-delete]

then use git cherry to compare it to your main development branch:

git cherry -v master

Example output:

+ 8a14709d08c99c36e907e47f9c4dacebeff46ecb Commit message
+ b30ccc3fb38d3d64c5fef079a761c7e0a5c7da81 Another commit message
- 85867e38712de930864c5edb7856342e1358b2a0 Yet another message

Note: The -v flag is to include the commit message along with the SHA hash.

Lines with the '+' in front are in the branch-to-delete, but not the master branch. Those with a '-' in front have an equivalent commit in master.

For JUST the commits that aren't in master, combine cherry pick with grep:

git cherry -v master | grep "^\+"

Example output:

+ 8a14709d08c99c36e907e47f9c4dacebeff46ecb Commit message
+ b30ccc3fb38d3d64c5fef079a761c7e0a5c7da81 Another commit message

No need to uninstall old python versions.

Just install new version say python-3.3.2-macosx10.6.dmg and change the soft link of python to newly installed python3.3

Check the path of default python and python3.3 with following commands

"which python" and "which python3.3"

then delete existing soft link of python and point it to python3.3

if you are getting id from url try

$id = (isset($_GET['id']) ? $_GET['id'] : '');

if getting from form you need to use POST method cause your form has method="post"

 $id = (isset($_POST['id']) ? $_POST['id'] : '');

For php notices use isset() or empty() to check values exist or not or initialize variable first with blank or a value

$id= '';

Please check out my component that will help you to allow only a particular data type. Currently supporting integer, decimal, string and time(HH:MM).

• string - String is allowed with optional max length
• integer - Integer only allowed with optional max value
• decimal - Decimal only allowed with optional decimal points and max value (by default 2 decimal points)
• time - 24 hr Time format(HH:MM) only allowed

Hope that helps.

Below we use a boolean "first" argument to switch between first match and all matches (a default which is equivalent to "find . -name file"):

import  os

def find(root, file, first=False):
    for d, subD, f in os.walk(root):
        if file in f:
            print("{0} : {1}".format(file, d))
            if first == True:
                break 

Add a css class:

.disable_a_href{
    pointer-events: none;
}

Add this jquery:

$("#ThisLink").addClass("disable_a_href"); 

According to this article on the w3c website:

CDATA is a sequence of characters from the document character set and may include character entities. User agents should interpret attribute values as follows:

• Replace character entities with characters,
• Ignore line feeds,
• Replace each carriage return or tab with a single space.

This means that (at least) CR and LF won't work inside title attribute. I suggest that you use a tooltip plugin. Most of these plugins allow arbitrary HTML to be displayed as an element's tooltip.

I updated to 0.3.0 and had the same issue. I had to end up changing my Gradle version to classpath 'com.android.tools.build:gradle:0.6.1+' and in build.gradle and also changing the distributionUrl to distributionUrl=http\://services.gradle.org/distributions/gradle-1.8-bin.zip in the gradle-wrapper.properties file. Then I did a local import of the Gradle file. That worked for me.

                    {
                        plaintext = srDecrypt.ReadToEnd();
                    }

• Cntml (http://cntlm.sourceforge.net/)

It authenticates you against normal or even Windows NTLM proxy and starts localhost-proxy without authentication.

In order to get it run:

• Install Cntml
• Configure Cntml according to documentation to pass your proxy authentication

• Point git to your new localhost proxy:

  [http]
      proxy = http://localhost:3128       # change port as necessary
  

One alternative to using Tensorflow C++ API I found is to use cppflow.

It's a lightweight C++ wrapper around Tensorflow C API. You get very small executables and it links against the libtensorflow.so already compiled file. There are also examples of use and you use CMAKE instead of Bazel.

I would rather use Last() from LINQ to do it.

rows = rows.Remove(rows.Last());

or

rows = rows.Remove(rows.LastOrDefault());

you could also store your data in an service with an setter and get it over a getter

import { Injectable } from '@angular/core';

@Injectable()
export class StorageService {

    public scope: Array<any> | boolean = false;

    constructor() {
    }

    public getScope(): Array<any> | boolean {
        return this.scope;
    }

    public setScope(scope: any): void {
        this.scope = scope;
    }
}

Alright, so I got it working by changing this

log4j.rootLogger=DebugAppender

to this

log4j.rootLogger=DEBUG, DebugAppender

Apparently you have to specify the logging level to the rootLogger first? I apologize if I wasted anyone's time.

Also, I decided to answer my own question because this wasn't a classpath issue.

At the beginning of your loading script, just make your

visible through css [display:block;] and make the rest of the page invisible through css[display:none;].

Once the loading is done, just make the loading invisible and the page visible again with the same technique. You can use the document.getElementById() to select the divs you want to change the display.

Edit: Here's what it would sort of look like. When the body finishes loading, it will call the javascript function that will change the display values of the different elements. By default, your style would be to have the page not visible the loading visible.

<head>
    <style>
        #page{
            display: none;
        }
        #loading{
            display: block;
        }
    </style>
    <script>
        function myFunction()
        {
            document.getElementById("page").style.display = "block";
            document.getElementById("loading").style.display = "none";
        }
    </script>
</head>

<body onload="myFunction()">
    <div id="page">

    </div>
    <div id="loading">

    </div>
</body>

Ummm, you guys are forgetting the Character.isLetterOrDigit method:

boolean x;
String character = in.next();
char c = character.charAt(0);
if(Character.isLetterOrDigit(charAt(c)))
{ 
  x = true;
}

Use JSON.

In the following example $php_variable can be any PHP variable.

<script type="text/javascript">
    var obj = <?php echo json_encode($php_variable); ?>;
</script>

In your code, you could use like the following:

drawChart(600/50, <?php echo json_encode($day); ?>, ...)

In cases where you need to parse out an object from JSON-string (like in an AJAX request), the safe way is to use JSON.parse(..) like the below:

var s = "<JSON-String>";
var obj = JSON.parse(s);

Take a look at the Mergent Historical Securities Data API - http://www.mergent.com/servius

Maybe grid on will suffice.

Just one addition to answers: If all these methods return false, even if strings seem to be equal, it is possible that there is a whitespace to the left and or right of one string. So, just put a .trim() at the end of strings before comparing:

if(s1.trim() === s2.trim())
{
    // your code
}

I have lost hours trying to figure out what is wrong. Hope this will help to someone!

Updated version of iksnae's awesome answer. It's not a regex, but I think it's the best solution to validate all countries' phone numbers as it is smart enough to know if the country's phone extension code is valid as well.

extension String {
    public var validPhoneNumber: Bool {
        let types: NSTextCheckingResult.CheckingType = [.phoneNumber]
        guard let detector = try? NSDataDetector(types: types.rawValue) else { return false }
        if let match = detector.matches(in: self, options: [], range: NSMakeRange(0, self.count)).first?.phoneNumber {
            return match == self
        } else {
            return false
        }
    }
}

print("\("+96 (123) 456-0990".validPhoneNumber)") //returns false, smart enough to know if country phone code is valid as well 
print("\("+994 (123) 456-0990".validPhoneNumber)") //returns true because +994 country code is an actual country phone code
print("\("(123) 456-0990".validPhoneNumber)") //returns true
print("\("123-456-0990".validPhoneNumber)") //returns true
print("\("1234560990".validPhoneNumber)") //returns true

Here is a solution which:

• Is self contained
• Does not require VBA
• Is not limited in the same way as IF regarding bucket maximums
• Does not require precise values as LOOKUP does

=INDEX({"Small","Medium","Large"},LARGE(IF([INPUT_VALUE]>{0,11,21},{1,2,3}),1))

Replace [INPUT_VALUE] with the appropriate cell reference and make sure to press Ctrl+Shift+Enter as this is an array formula.

Each of the array constants can be expanded to be arbitrarily long; as long as the formula does not exceed Excel's maximum of 8,192 characters. The first constant should contain the return values, the second should contain ordered thresholds,and the third should simply be ascending integers.

You may be interested in the Unicode categories "Other, Control" and possibly "Other, Format" (unfortunately the latter seems to contain both unprintable and printable characters).

In Java regular expressions you can check for them using \p{Cc} and \p{Cf} respectively.

This is how i did it:

1. Locate in the /etc/php5/apache2/php.ini

   post_max_size = 8M
   upload_max_filesize = 2M
   

2. Edit it as

   post_max_size = 48M
   upload_max_filesize = 42M
   

(Which is more then enough)

Restarted the apache:

sudo /etc/init.d/apache2 restart

You have to disable Memory Integrity.

Go to Device Security, then Core Isolation, disable Memory Integrity and reboot.

It seems that Memory Integrity virtualizes some processes (in this case, VMware) and we get that error.

You can also disable Memory Integrity from Registry Editor if your control panel was saying 'This is managed by your administrator'.

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity

Double click on Enabled and change its value from 1 to 0 to disable it.

Rather than defining contact_email within app.config, define it in a parameters entry:

parameters:
    contact_email: [email protected]

You should find the call you are making within your controller now works.

You can also use the hasFocus() method:

public void onTextChanged(CharSequence s, int start,
     int before, int count) {
     if (Field2.hasfocus()){
         Field1.setText("");
     }

nginx is useful for forwarding HTTP on many platforms including Windows. It's easy to setup and extend with more advanced configuration. A basic configuration could look something like this:

events {}

http {
     server {

        listen 192.168.1.111:4422;

        location / {
            proxy_pass http://192.168.2.33:80/;
        }
     }
}

public static int median(int[] arr) {
int median = 0;
java.util.Arrays.sort(arr);
        
for (int i=0;i<arr.length;i++) {
            
    if (arr.length % 2 == 1) {
        median = Math.round(arr[arr.length/2]);
    } else {
        median = (arr[(arr.length/2)] + arr[(arr.length/2)-1])/2;
    }
}
return median;

}

First initialize Property values

MutablePropertyValues mutablePropertyValues = new MutablePropertyValues();
mutablePropertyValues.add("hostName", details.getHostName());
mutablePropertyValues.add("port", details.getPort());

DefaultListableBeanFactory context = new DefaultListableBeanFactory();
GenericBeanDefinition connectionFactory = new GenericBeanDefinition();
connectionFactory.setBeanClass(Class);
connectionFactory.setPropertyValues(mutablePropertyValues);

context.registerBeanDefinition("beanName", connectionFactory);

Add to the list of beans

ConfigurableListableBeanFactory beanFactory = ((ConfigurableApplicationContext) applicationContext).getBeanFactory();
beanFactory.registerSingleton("beanName", context.getBean("beanName"));

If you are interested in only selecting one column this will work.

df[["item1"]].to_dict("records")

The below will NOT work and produces a TypeError: unsupported type: . I believe this is because it is trying to convert a series to a dict and not a Data Frame to a dict.

df["item1"].to_dict("records")

I had a requirement to only select one column and convert it to a list of dicts with the column name as the key and was stuck on this for a bit so figured I'd share.

Additional Information.

This is a bit high-level answer for applications which want to seamlessly fit into the Windows environment. Technical details of playing particular sound were provided in other answers. Besides that, always note these two points:

1. Use five standard system sounds in typical scenarios, i.e.

   • Asterisk - play when you want to highlight current event

   • Question - play with questions (system message box window plays this one)

   • Exclamation - play with excalamation icon (system message box window plays this one)

   • Beep (default system sound)

   • Critical stop ("Hand") - play with error (system message box window plays this one)
      

   Methods of class System.Media.SystemSounds will play them for you.
    

2. Implement any other sounds as customizable by your users in Sound control panel

   • This way users can easily change or remove sounds from your application and you do not need to write any user interface for this – it is already there
   • Each user profile can override these sounds in own way
   • How-to:
     • Create sound profile of your application in the Windows Registry (Hint: no need of programming, just add the keys into installer of your application.)
     • In your application, read sound file path or DLL resource from your registry keys and play it. (How to play sounds you can see in other answers.)

I've created the tiniest code to do exactly that. It's not only for counting but for any task that needs to run in a given time. (let's say, do something for 5 seconds):

• Codepen Demo Page

• Do-In: Github Project (super lightweight tiny script)

Demo:

var step = function(t, elapsed){
    // easing 
    t = t*t*t;

    // calculate new value
    var value = 300 * t; // will count from 0 to 300

    // limit value ("t" might be higher than "1")
    if( t > 0.999 )
        value = 300;

    // print value (converts it to an integer)
    someElement.innerHTML = value|0;
};

var done = function(){
    console.log('done counting!');
};


// Do-in settings object
var settings = {
    step     : step,
    duration : 3,
    done     : done,
    fps      : 24 // optional. Default is requestAnimationFrame
};

// initialize "Do-in" instance 
var doin = new Doin(settings);

Unicode Standard for Media Control Symbols

Pause: ??

The Unicode Standard 13.0 (update 2020) provides the Miscellaneous Technical glyphs in the HEX range 2300–23FF

Miscellaneous Technical

Given the extensive Unicode 13.0 documentation, some of the glyphs we can associate to common Media control symbols would be as following:

Keyboard and UI symbols

23CF ⏏︎ Eject media

User interface symbols

23E9 ⏩︎ fast forward
23EA ⏪︎ rewind, fast backwards
23EB ⏫︎ fast increase
23EC ⏬︎ fast decrease
23ED ⏭︎ skip to end, next
23EE ⏮︎ skip to start, previous
23EF ⏯︎ play/pause toggle
23F1 ⏱︎ stopwatch
23F2 ⏲︎ timer clock
23F3 ⏳︎ hourglass
23F4 ⏴︎ reverse, back
23F5 ⏵︎ forward, next, play
23F6 ⏶︎ increase
23F7 ⏷︎ decrease
23F8 ⏸︎ pause
23F9 ⏹︎ stop
23FA ⏺︎ record

Power symbols from ISO 7000:2012

23FB ?︎ standby/power
23FC ?︎ power on/off
23FD ?︎ power on
2B58 ?︎ power off

Power symbol from IEEE 1621-2004

23FE ?︎ power sleep

Use on the Web:

A file must be saved using UTF-8 encoding without BOM (which in most development environments is set by default) in order to instruct the parser how to transform the bytes into characters correctly. <meta charset="utf-8"/> should be used immediately after <head> in a HTML file, and make sure the correct HTTP headers Content-Type: text/html; charset=utf-8 are set.

Examples:

⏩ Pictograph 
⏩︎ Standardized Variant

.icon-ff:before { content: "\23E9" }
.icon-ff--standard:before { content: "\23E9\FE0E" }

EL_iconFF.textContent = "\u23E9";
EL_iconFF_standard.textContent = "\u23E9\uFE0E"

Standardized variant

To prevent a glyph from being "color-emojified" ⏩︎ / ⏩ append the code U+FE0E Text Presentation Selector to request a Standardized variant: (example: ⏩︎)

Inconsistencies

Characters in the Unicode range are susceptible to the font-family environment they are used, application, browser, OS, platform.
When unknown or missing - we might see symbols like � or ▯ instead, or even inconsistent behavior due to differences in HTML parser implementations by different vendors.
For example, on Windows Chromium browsers the Standardized Variant suffix U+FE0E is buggy, and such symbols are still better accompanied by CSS i.e: font-family: "Segoe UI Symbol" to force that specific Font over the Colored Emoji (usually recognized as "Segoe UI Emoji") - which defies the purpose of U+FE0E in the first place - time will tell…

Scalable icon fonts

To circumvent problems related to unsupported characters - a viable solution is to use scalable icon font-sets like i.e:

and many other you can find in the wild; and last but not least, this really useful online tool: font-icons generator, Icomoon.io.

Not too sure there is need for this, and to me lack of tools suggests lack of need. JSON is best processed as objects (the way it's done in JS anyway), and you typically use language of the objects itself to do transformations (Java for Java objects created from JSON, same for Perl, Python, Perl, c#, PHP and so on). Just with normal assignments (or set, get), looping and so on.

I mean, XSLT is just another language, and one reason it is needed is that XML is not an object notation and thus objects of programming languages are not exact fits (impedance between hierarchic xml model and objects/structs).

I found the solution, Problem started when I updated sdk, after that I used different buildToolsVersion ('22.0.1') and I was using different support library like compile 'com.android.support:appcompat-v7:23.0.0', showing you in image below

This was raising problem of "android.widget.Material..." Then I used same version for support library like compile 'com.android.support:appcompat-v7:22.0.1' and its DONE. (Showing you in below screenshot)

I also had the same problem. I published an App in Test mode created with React Native 59. it wasn't compatible for certain tester. The message wasn't clear about why the app is not compatible , after i figured out that i restricted the app to be available only for certain country . that was the problem, but as i said the message wasn't clear. in Play Store WebApp the message is: "this app is not compatible with your device". in the mobile app the message "This app is not available in your country"

Basically what others have already posted but IMHO a bit cleaner:

$('<iframe/>', {
    src: 'https://example.com/',
    load: function() {
        alert("loaded")
    }
}).appendTo('body');

I was having trouble coloring rows in table using bootstrap table-striped class then realized delete table-striped class and do this in css file

tr:nth-of-type(odd)
{  
background-color: red;
}
tr:nth-of-type(even)
{  
background-color: blue;
}

The bootstrap table-striped class will over ride your selectors.

You have to call

setPadding(int left, int top, int right, int bottom)

like so: your_view.setPadding(0,16,0,0)

What you are trying to use is only the getter.

Android studio shows what padding...() actually means in java:

padding example The image shows it only calls getPadding...()

If you want to add a margin to your TextView you will have to LayoutParams:

val params =  LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT)
params.setMargins(int left, int top, int right, int bottom)
your_view.layoutParams = params

With text files, maybe the EOF is -1 when using BufferReader.read(), char by char. I made a test with BufferReader.readLine()!=null and it worked properly.

Try this one:

let uuid = NSUUID().uuidString
print(uuid)

Swift 3/4/5

let uuid = UUID().uuidString
print(uuid)

Use:

document.location.href = "http://yoursite.com" + document.getElementById('somefield');

That would get the value of some text field or hidden field, and add it to your site URL to get a new URL (href). You can modify this to suit your needs.

Locating the different building blocks is done in the request life cycle. One of the first steps in the ASP.NET MVC request life cycle is mapping the requested URL to the correct controller action method. This process is referred to as routing. A default route is initialized in the Global.asax file and describes to the ASP.NET MVC framework how to handle a request. Double-clicking on the Global.asax file in the MvcApplication1 project will display the following code:

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.Routing;

namespace MvcApplication1 {

   public class GlobalApplication : System.Web.HttpApplication
   {
       public static void RegisterRoutes(RouteCollection routes)
       {
           routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

           routes.MapRoute(
               "Default",                                          // Route name
               "{controller}/{action}/{id}",                       // URL with parameters
               new { controller = "Home", action = "Index",
                     id = "" }  // Parameter defaults
           );

       }

       protected void Application_Start()
       {
           RegisterRoutes(RouteTable.Routes);
       }
   }

}

In the Application_Start() event handler, which is fired whenever the application is compiled or the web server is restarted, a route table is registered. The default route is named Default, and responds to a URL in the form of http://www.example.com/{controller}/{action}/{id}. The variables between { and } are populated with actual values from the request URL or with the default values if no override is present in the URL. This default route will map to the Home controller and to the Index action method, according to the default routing parameters. We won't have any other action with this routing map.

By default, all the possible URLs can be mapped through this default route. It is also possible to create our own routes. For example, let's map the URL http://www.example.com/Employee/Maarten to the Employee controller, the Show action, and the firstname parameter. The following code snippet can be inserted in the Global.asax file we've just opened. Because the ASP.NET MVC framework uses the first matching route, this code snippet should be inserted above the default route; otherwise the route will never be used.

routes.MapRoute(

   "EmployeeShow",                    // Route name
   "Employee/{firstname}",            // URL with parameters
    new {                             // Parameter defaults
       controller = "Employee",
       action = "Show", 
       firstname = "" 
   }  

);

Now, let's add the necessary components for this route. First of all, create a class named EmployeeController in the Controllers folder. You can do this by adding a new item to the project and selecting the MVC Controller Class template located under the Web | MVC category. Remove the Index action method, and replace it with a method or action named Show. This method accepts a firstname parameter and passes the data into the ViewData dictionary. This dictionary will be used by the view to display data.

The EmployeeController class will pass an Employee object to the view. This Employee class should be added in the Models folder (right-click on this folder and then select Add | Class from the context menu). Here's the code for the Employee class:

namespace MvcApplication1.Models {

   public class Employee
   {
       public string FirstName { get; set; }
       public string LastName { get; set; }
       public string Email { get; set; }
   }

} 

's up guys i read every single forum about this topic i still had problem (occurred trying to project from git)

after 4 hours and a lot of swearing i solved this issue by myself just by changing target framework setting in project properties (right click on project -> properties) -> application and changed target framework from .net core 3.0 to .net 5.0 i hope it will help anybody

happy coding gl hf nerds

This is intended behavior.

When you make an HTTP request, the server normally returns code 200 OK. If you set If-Modified-Since, the server may return 304 Not modified (and the response will not have the content). This is supposed to be your cue that the page has not been modified.

The authors of the class have foolishly decided that 304 should be treated as an error and throw an exception. Now you have to clean up after them by catching the exception every time you try to use If-Modified-Since.

Here are my steps tried with NPP 7.8.2:

(1)Download the plugins zip (refer plugin-full-list json):

https://github.com/notepad-plus-plus/nppPluginList/blob/master/src/pl.x64.json

(2)Extract the files (normally .dll lib files) from zip to npp's plugins sub-folder

E.g., extract NppFTP-x64.zip into C:\Program Files\Notepad++\plugins\NppFTP

Keep in mind:

  (i)Must create sub-folder for each plugin
 (ii)The sub-folder's name must be EXACTLY SAME as the main .dll filename (e.g., NppFTP.dll)

(3)Restart npp, those plugin will be automatically loaded.

[Note-1]: I didn't do setting->import->plugin, it seems this is not required [Note-2]: You may need start npp with "run as administrator" option if you want to do import plugin.

A different point is that the first sentence is parsed as:

scala> List(1,2,3).++(List(4,5))
res0: List[Int] = List(1, 2, 3, 4, 5)

Whereas the second example is parsed as:

scala> List(4,5).:::(List(1,2,3))
res1: List[Int] = List(1, 2, 3, 4, 5)

So if you are using macros, you should take care.

Besides, ++ for two lists is calling ::: but with more overhead because it is asking for an implicit value to have a builder from List to List. But microbenchmarks did not prove anything useful in that sense, I guess that the compiler optimizes such calls.

Micro-Benchmarks after warming up.

scala>def time(a: => Unit): Long = { val t = System.currentTimeMillis; a; System.currentTimeMillis - t}
scala>def average(a: () => Long) = (for(i<-1 to 100) yield a()).sum/100

scala>average (() => time { (List[Int]() /: (1 to 1000)) { case (l, e) => l ++ List(e) } })
res1: Long = 46
scala>average (() => time { (List[Int]() /: (1 to 1000)) { case (l, e) => l ::: List(e ) } })
res2: Long = 46

As Daniel C. Sobrai said, you can append the content of any collection to a list using ++, whereas with ::: you can only concatenate lists.

You can use the substring method of JavaScript string objects:

s = s.substring(0, s.length - 4)

It unconditionally removes the last four characters from string s.

However, if you want to conditionally remove the last four characters, only if they are exactly _bar:

var re = /_bar$/;
s.replace(re, "");

Try this:

DisplayMetrics dm = context.getResources().getDisplayMetrics();
int densityDpi = dm.densityDpi;

By default, you can access your databases at http:// localhost/phpmyadmin using user: root and a blank password.

Once logged in PHPmyAdmin, click on the Privileges tab. and on the Add a new user link located under the User Overview table

var fallbackUrl = "home.php";
if(history.back() === undefined)
    window.location.href = fallbackUrl;

Since this is the first SO thread that seemed to come up for me when searching for "unresolved externals with static const members" in general, I'll leave another hint to solve one problem with unresolved externals here:

For me, the thing that I forgot was to mark my class definition __declspec(dllexport), and when called from another class (outside that class's dll's boundaries), I of course got the my unresolved external error.
Still, easy to forget when you're changing an internal helper class to a one accessible from elsewhere, so if you're working in a dynamically linked project, you might as well check that, too.

There is an inspiration here. Just utilize shell regex or git regex.

git checkout commit_id */*.bat  # *.bat in 1-depth subdir exclude current dir, shell regex  
git checkout commit_id '*.bat'  # *.bat in all subdir include current dir, git regex

Use quotation to escape shell regex interpretation and pass wildcards to git.

The first one is not recursive, only files in 1-depth subdir. But the second one is recursive.

As for your situation, the following may be enough.

git checkout master */*/wp-content/*/*
git checkout master '*/wp-content/*'

Just hack the lines as required.

It should be,

*/15 * * * *  your_command_or_whatever

It's notable to understand that if you'd like to conditionally add attributes you can also add a dynamic declaration:

<input v-bind="attrs" />

where attrs is declared as an object:

data() {
    return {
        attrs: {
            required: true,
            type: "text"
        }
    }
}

Which will result in:

<input required type="text"/>

Ideal in cases with multiple attributes.

SQLDataReaders are forward-only. You're essentially doing this:

count++;  // initially 1
.DataBind(); //consuming all the records

//next iteration on
.Read()
//we've now come to end of resultset, thanks to the DataBind()
//count is still 1 

You could do this instead:

if (reader.HasRows)
{
    rep.DataSource = reader;
    rep.DataBind();
}
int count = rep.Items.Count; //somehow count the num rows/items `rep` has.

Just another way to retrieve the same data using INFORMATION_SCHEMA

The information schema views included in SQL Server comply with the ISO standard definition for the INFORMATION_SCHEMA.

I like simple.

• The Fred activity has two modes -- HAPPY and SAD.
• Create a static IntentFactory that creates your Intent for you. Pass it the Mode you want.
• The IntentFactory uses the name of the Mode class as the name of the extra.
• The IntentFactory converts the Mode to a String using name()
• Upon entry into onCreate use this info to convert back to a Mode.

• You could use ordinal() and Mode.values() as well. I like strings because I can see them in the debugger.

  public class Fred extends Activity {
  
      public static enum Mode {
          HAPPY,
          SAD,
          ;
      }
  
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.betting);
          Intent intent = getIntent();
          Mode mode = Mode.valueOf(getIntent().getStringExtra(Mode.class.getName()));
          Toast.makeText(this, "mode="+mode.toString(), Toast.LENGTH_LONG).show();
      }
  
      public static Intent IntentFactory(Context context, Mode mode){
          Intent intent = new Intent();
          intent.setClass(context,Fred.class);
          intent.putExtra(Mode.class.getName(),mode.name());
  
          return intent;

When you use git push origin :staleStuff, it automatically removes origin/staleStuff, so when you ran git remote prune origin, you have pruned some branch that was removed by someone else. It's more likely that your co-workers now need to run git prune to get rid of branches you have removed.

So what exactly git remote prune does? Main idea: local branches (not tracking branches) are not touched by git remote prune command and should be removed manually.

Now, a real-world example for better understanding:

You have a remote repository with 2 branches: master and feature. Let's assume that you are working on both branches, so as a result you have these references in your local repository (full reference names are given to avoid any confusion):

• refs/heads/master (short name master)
• refs/heads/feature (short name feature)
• refs/remotes/origin/master (short name origin/master)
• refs/remotes/origin/feature (short name origin/feature)

Now, a typical scenario:

1. Some other developer finishes all work on the feature, merges it into master and removes feature branch from remote repository.
2. By default, when you do git fetch (or git pull), no references are removed from your local repository, so you still have all those 4 references.
3. You decide to clean them up, and run git remote prune origin.
4. git detects that feature branch no longer exists, so refs/remotes/origin/feature is a stale branch which should be removed.
5. Now you have 3 references, including refs/heads/feature, because git remote prune does not remove any refs/heads/* references.

It is possible to identify local branches, associated with remote tracking branches, by branch.<branch_name>.merge configuration parameter. This parameter is not really required for anything to work (probably except git pull), so it might be missing.

(updated with example & useful info from comments)

You can do the following in EF 4.1:

var result = from x in appEntities
             where x.id = 32
             select x;

System.Diagnostics.Trace.WriteLine(result .ToString());

That will give you the SQL that was generated.

As mentioned by ecdpalma below, git 1.7.12+ (August 2012) has enhanced the option --root for git rebase:

"git rebase [-i] --root $tip" can now be used to rewrite all the history leading to "$tip" down to the root commit.

That new behavior was initially discussed here:

I personally think "git rebase -i --root" should be made to just work without requiring "--onto" and let you "edit" even the first one in the history.
It is understandable that nobody bothered, as people are a lot less often rewriting near the very beginning of the history than otherwise.

The patch followed.

(original answer, February 2010)

As mentioned in the Git FAQ (and this SO question), the idea is:

1. Create new temporary branch
2. Rewind it to the commit you want to change using git reset --hard
3. Change that commit (it would be top of current HEAD, and you can modify the content of any file)

4. Rebase branch on top of changed commit, using:

   git rebase --onto <tmp branch> <commit after changed> <branch>`
   

The trick is to be sure the information you want to remove is not reintroduced by a later commit somewhere else in your file. If you suspect that, then you have to use filter-branch --tree-filter to make sure the content of that file does not contain in any commit the sensible information.

In both cases, you end up rewriting the SHA1 of every commit, so be careful if you have already published the branch you are modifying the contents of. You probably shouldn’t do it unless your project isn’t yet public and other people haven’t based work off the commits you’re about to rewrite.

Managed to get the input field value by doing something like this:

import React, { Component } from 'react';

class App extends Component {

constructor(props){
super(props);

this.state = {
  username : ''
}

this.updateInput = this.updateInput.bind(this);
this.handleSubmit = this.handleSubmit.bind(this);
}


updateInput(event){
this.setState({username : event.target.value})
}


handleSubmit(){
console.log('Your input value is: ' + this.state.username)
//Send state to the server code
}



render(){
return (
    <div>
    <input type="text" onChange={this.updateInput}></input>
    <input type="submit" onClick={this.handleSubmit} ></input>
    </div>
  );
}
} 

//output
//Your input value is: x

- , ,

function forEachNested(O, f, cur){
    O = [ O ]; // ensure that f is called with the top-level object
    while (O.length) // keep on processing the top item on the stack
        if(
           !f( cur = O.pop() ) && // do not spider down if `f` returns true
           cur instanceof Object && // ensure cur is an object, but not null 
           [Object, Array].includes(cur.constructor) //limit search to [] and {}
        ) O.push.apply(O, Object.values(cur)); //search all values deeper inside
}

To use the above function, pass the array as the first argument and the callback function as the second argument. The callback function will receive 1 argument when called: the current item being iterated.

(function(){"use strict";

var cars = {"label":"Autos","subs":[{"label":"SUVs","subs":[]},{"label":"Trucks","subs":[{"label":"2 Wheel Drive","subs":[]},{"label":"4 Wheel Drive","subs":[{"label":"Ford","subs":[]},{"label":"Chevrolet","subs":[]}]}]},{"label":"Sedan","subs":[]}]};

var lookForCar = prompt("enter the name of the car you are looking for (e.g. 'Ford')") || 'Ford';
lookForCar = lookForCar.replace(/[^ \w]/g, ""); // incaseif the user put quotes or something around their input
lookForCar = lookForCar.toLowerCase();

var foundObject = null;
forEachNested(cars, function(currentValue){
    if(currentValue.constructor === Object &&
      currentValue.label.toLowerCase() === lookForCar) {
        foundObject = currentValue;
    }
});
if (foundObject !== null) {
    console.log("Found the object: " + JSON.stringify(foundObject, null, "\t"));
} else {
    console.log('Nothing found with a label of "' + lookForCar + '" :(');
}

function forEachNested(O, f, cur){
    O = [ O ]; // ensure that f is called with the top-level object
    while (O.length) // keep on processing the top item on the stack
        if(
           !f( cur = O.pop() ) && // do not spider down if `f` returns true
           cur instanceof Object && // ensure cur is an object, but not null 
           [Object, Array].includes(cur.constructor) //limit search to [] and {}
        ) O.push.apply(O, Object.values(cur)); //search all values deeper inside
}

})();

A "cheat" alternative might be to use JSON.stringify to iterate. HOWEVER, JSON.stringify will call the toString method of each object it passes over, which may produce undesirable results if you have your own special uses for the toString.

function forEachNested(O, f, v){
    typeof O === "function" ? O(v) : JSON.stringify(O,forEachNested.bind(0,f));
    return v; // so that JSON.stringify keeps on recursing
}

(function(){"use strict";

var cars = {"label":"Autos","subs":[{"label":"SUVs","subs":[]},{"label":"Trucks","subs":[{"label":"2 Wheel Drive","subs":[]},{"label":"4 Wheel Drive","subs":[{"label":"Ford","subs":[]},{"label":"Chevrolet","subs":[]}]}]},{"label":"Sedan","subs":[]}]};

var lookForCar = prompt("enter the name of the car you are looking for (e.g. 'Ford')") || 'Ford';
lookForCar = lookForCar.replace(/[^ \w]/g, ""); // incaseif the user put quotes or something around their input
lookForCar = lookForCar.toLowerCase();

var foundObject = null;
forEachNested(cars, function(currentValue){
    if(currentValue.constructor === Object &&
      currentValue.label.toLowerCase() === lookForCar) {
        foundObject = currentValue;
    }
});
if (foundObject !== null)
    console.log("Found the object: " + JSON.stringify(foundObject, null, "\t"));
else
    console.log('Nothing found with a label of "' + lookForCar + '" :(');

function forEachNested(O, f, v){
    typeof O === "function" ? O(v) : JSON.stringify(O,forEachNested.bind(0,f));
    return v; // so that JSON.stringify keeps on recursing
}
})();

However, while the above method might be useful for demonstration purposes, Object.values is not supported by Internet Explorer and there are many terribly illperformant places in the code:

1. the code changes the value of input parameters (arguments) [lines 2 & 5],
2. the code calls Array.prototype.push and Array.prototype.pop on every single item [lines 5 & 8],
3. the code only does a pointer-comparison for the constructor which does not work on out-of-window objects [line 7],
4. the code duplicates the array returned from Object.values [line 8],
5. the code does not localize window.Object or window.Object.values [line 9],
6. and the code needlessly calls Object.values on arrays [line 8].

Below is a much much faster version that should be far faster than any other solution. The solution below fixes all of the performance problems listed above. However, it iterates in a much different way: it iterates all the arrays first, then iterates all the objects. It continues to iterate its present type until complete exhaustion including iteration subvalues inside the current list of the current flavor being iterated. Then, the function iterates all of the other type. By iterating until exhaustion before switching over, the iteration loop gets hotter than otherwise and iterates even faster. This method also comes with an added advantage: the callback which is called on each value gets passed a second parameter. This second parameter is the array returned from Object.values called on the parent hash Object, or the parent Array itself.

var foundObject = null;
forEachNested(cars, function(currentValue){
    if(currentValue.constructor === Object &&
      currentValue.label.toLowerCase() === lookForCar) {
        foundObject = currentValue;
    }
});
if (foundObject !== null) {
    console.log("Found the object: " + JSON.stringify(foundObject, null, "\t"));
} else {
    console.log('Nothing found with a label of "' + lookForCar + '" :(');
}

})();

If you have a problem with circular references (e.g. having object A's values being object A itself in such as that object A contains itself), or you just need the keys then the following slower solution is available.

function forEachNested(O, f){
    O = Object.entries(O);
    var cur;
    function applyToEach(x){return cur[1][x[0]] === x[1]} 
    while (O.length){
        cur = O.pop();
        f(cur[0], cur[1]);
        if (typeof cur[1] === 'object' && cur[1].constructor === Object && 
          !O.some(applyToEach))
            O.push.apply(O, Object.entries(cur[1]));
    }
}

Because these methods do not use any recursion of any sort, these functions are well suited for areas where you might have thousands of levels of depth. The stack limit varies greatly from browser to browser, so recursion to an unknown depth is not very wise in Javascript.

I am posting this as an answer because this is very important as of PHP 7.4.

The opcache.preload mechanism of PHP 7.4 makes it possible to preload opcodes for classes. If you use it to preload a file that contains a class definition and some side effects, then classes defined in that file will "exist" for all subsequent scripts executed by this FPM server and its workers, but the side effects will not be in effect, and the autoloader will not require the file containing them because the class already "exists". This completely defeats any and all static initialization techniques that rely on executing top-level code in the file that contains the class definition.

You need to set the path of maven under Global setting like MAVEN_HOME

/user/share/maven

and make sure the workbench have permission of read, write and delete "777"

Here's a simple php4-friendly implementation:

/**
* Builds an http query string.
* @param array $query  // of key value pairs to be used in the query
* @return string       // http query string.
**/
function build_http_query( $query ){

    $query_array = array();

    foreach( $query as $key => $key_value ){

        $query_array[] = urlencode( $key ) . '=' . urlencode( $key_value );

    }

    return implode( '&', $query_array );

}

Python dictionaries have a key and a value, what you are asking for is what key(s) point to a given value.

You can only do this in a loop:

[k for (k, v) in i.iteritems() if v == 0]

Note that there can be more than one key per value in a dict; {'a': 0, 'b': 0} is perfectly legal.

If you want ordering you either need to use a list or a OrderedDict instance instead:

items = ['a', 'b', 'c']
items.index('a') # gives 0
items[0]         # gives 'a'

You can add references to your model through command line in the following manner:

rails g migration add_column_to_tester user_id:integer

This will generate a migration file like :

class AddColumnToTesters < ActiveRecord::Migration
  def change
    add_column :testers, :user_id, :integer
  end
end

This works fine every time i use it..

For the answer above, the default serial port is

        serialParams.BaudRate = 9600;
        serialParams.ByteSize = 8;
        serialParams.StopBits = TWOSTOPBITS;
        serialParams.Parity = NOPARITY;

I use sublime Text on linux.
