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)

here's my 2 cents worth:

• resuable function forpromise()
• emulates a classic for loop
• allows for early exit based on internal logic, returning a value
• can collect an array of results passed into resolve/next/collect
• defaults to start=0,increment=1
• exceptions thrown inside loop are caught and passed to .catch()

typedef struct{
     char name[30];
     char surname[30];
     int age;
} data;

defines that data should be a block of memory that fits 60 chars plus 4 for the int (see note)

[----------------------------,------------------------------,----]
 ^ this is name              ^ this is surname              ^ this is age

This allocates the memory on the stack.

data s1;

Assignments just copies numbers, sometimes pointers.

This fails

s1.name = "Paulo";

because the compiler knows that s1.name is the start of a struct 64 bytes long, and "Paulo" is a char[] 6 bytes long (6 because of the trailing \0 in C strings)
Thus, trying to assign a pointer to a string into a string.

To copy "Paulo" into the struct at the point name and "Rossi" into the struct at point surname.

memcpy(s1.name,    "Paulo", 6);
memcpy(s1.surname, "Rossi", 6);
s1.age = 1;

You end up with

[Paulo0----------------------,Rossi0-------------------------,0001]

strcpy does the same thing but it knows about \0 termination so does not need the length hardcoded.

Alternatively you can define a struct which points to char arrays of any length.

typedef struct {
  char *name;
  char *surname;
  int age;
} data;

This will create

[----,----,----]

This will now work because you are filling the struct with pointers.

s1.name = "Paulo";
s1.surname = "Rossi";
s1.age = 1;

Something like this

[---4,--10,---1]

Where 4 and 10 are pointers.

Note: the ints and pointers can be different sizes, the sizes 4 above are 32bit as an example.

I figured it out. I had an error in my cloud formation template that was creating the EC2 instances. As a result, the EC2 instances that were trying to access the above code deploy buckets, were in different regions (not us-west-2). It seems like the access policies on the buckets (owned by Amazon) only allow access from the region they belong in. When I fixed the error in my template (it was wrong parameter map), the error disappeared

SQlite3 has a method named row_factory. This method would allow you to access the values by column name.

Promises are not callbacks. A promise represents the future result of an asynchronous operation. Of course, writing them the way you do, you get little benefit. But if you write them the way they are meant to be used, you can write asynchronous code in a way that resembles synchronous code and is much more easy to follow:

api().then(function(result){
    return api2();
}).then(function(result2){
    return api3();
}).then(function(result3){
     // do work
});

Certainly, not much less code, but much more readable.

But this is not the end. Let's discover the true benefits: What if you wanted to check for any error in any of the steps? It would be hell to do it with callbacks, but with promises, is a piece of cake:

api().then(function(result){
    return api2();
}).then(function(result2){
    return api3();
}).then(function(result3){
     // do work
}).catch(function(error) {
     //handle any error that may occur before this point
});

Pretty much the same as a try { ... } catch block.

Even better:

api().then(function(result){
    return api2();
}).then(function(result2){
    return api3();
}).then(function(result3){
     // do work
}).catch(function(error) {
     //handle any error that may occur before this point
}).then(function() {
     //do something whether there was an error or not
     //like hiding an spinner if you were performing an AJAX request.
});

And even better: What if those 3 calls to api, api2, api3 could run simultaneously (e.g. if they were AJAX calls) but you needed to wait for the three? Without promises, you should have to create some sort of counter. With promises, using the ES6 notation, is another piece of cake and pretty neat:

Promise.all([api(), api2(), api3()]).then(function(result) {
    //do work. result is an array contains the values of the three fulfilled promises.
}).catch(function(error) {
    //handle the error. At least one of the promises rejected.
});

Hope you see Promises in a new light now.

Try bellow code. This is help your code.

  $("#btnUpdate").on("click", function () {
            //alert("Alert Test");
            var url = 'http://cooktv.sndimg.com/webcook/sandbox/perf/topics.json';
            $.ajax({
                type: "GET",
                url: url,
                data: "{}",
                dataType: "json",
                contentType: "application/json; charset=utf-8",
                success: function (result) {
                    debugger;

                    $.each(result.callback, function (index, value) {
                        alert(index + ': ' + value.Name);
                    });
                },
                failure: function (result) { alert('Fail'); }
            });
        });

I could not access your url. Bellow error is shows

XMLHttpRequest cannot load http://cooktv.sndimg.com/webcook/sandbox/perf/topics.json. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:19829' is therefore not allowed access. The response had HTTP status code 501.

Timeouts

There are two main types of timeouts: connection timeouts and read timeouts. A connect timeout occurs if the timeout is hit while your client is attempting to establish a connection to a remote machine (corresponding to the connect() call on the socket). A read timeout occurs any time the server is too slow to send back a part of the response.

Note that connection timeouts emit an ETIMEDOUT error, and read timeouts emit an ECONNRESET error.

Similar situation for following configuration:

• Windows Server 2012 R2 Standard
• MS SQL server 2008 (tested also SQL 2012)
• Oracle 10g client (OracleDB v8.1.7)
• MSDAORA provider
• Error ID: 7302

My solution:

• Install 32bit MS SQL Server (64bit MSDAORA doesn't exist)
• Install 32bit Oracle 10g 10.2.0.5 patch (set W7 compatibility on setup.exe)
• Restart SQL services
• Check Allow in process in MSDAORA provider
• Test linked oracle server connection

Just replace the u' with a single quote...

print (str.replace(mail_accounts,"u'","'"))

In my case the ajax call was being interfered by the data-plugin tag applied to the table. The data-plugin does background initialization and will give this error when you have it as well as yourTable.DataTable({ ... }); initialization.

From

 <table id="myTable" class="table-class" data-plugin="dataTable" data-source="data-source">

To

<table id="myTable" class="table-class" data-source="data-source">

I had the same issue using IIS.

Make sure the option 'Enable 32bit Applications' is set to true on Advanced Configuration of the Application Pool.

If you need to process both the input file and user input (or anything else from stdin), then use the following solution:

#!/bin/bash
exec 3<"$1"
while IFS='' read -r -u 3 line || [[ -n "$line" ]]; do
    read -p "> $line (Press Enter to continue)"
done

Based on the accepted answer and on the bash-hackers redirection tutorial.

Here, we open the file descriptor 3 for the file passed as the script argument and tell read to use this descriptor as input (-u 3). Thus, we leave the default input descriptor (0) attached to a terminal or another input source, able to read user input.

here is another solution...

System.IO.Stream st = new System.IO.StreamReader (picturePath).BaseStream;
byte[] buffer = new byte[4096];

System.IO.MemoryStream m = new System.IO.MemoryStream ();
while (st.Read (buffer,0,buffer.Length) > 0) {
    m.Write (buffer, 0, buffer.Length);
}  
imgView.Tag = m.ToArray ();
st.Close ();
m.Close ();

hope it helps!

If you have cPanel hosting you can use Easy Apache to do this through shell. These are the steps.

1. Type the Easy Apache PathType the path for Easy Apache
   

   root@vps#### [~]# /scripts/easyapache

2. Do not say yes to the "cPanel update available".
3. Continue through the screens with defaults till you get to the "Exhaustive options list".
4. Page down till you see the Mbstring extension listed and select it.
5. Continue through the Steps and Save the Apache PHP build.

Apache and PHP will now rebuild to include the mbstring extension. Wait for the process to finish ~10 to 30 minutes. Once the process is finished you should see the Mbstring extension in the phpinfo now.

For more detailed steps see the article Installing the mbstring extension with Easy Apache

People have recommended MailChimp which is a good vendor for bulk email. If you're looking for a good vendor for transactional email, I might be able to help.

Over the past 6 months, we used four different SMTP vendors with the goal of figuring out which was the best one.

Here's a summary of what we found...

AuthSMTP

• Cheapest around
• No analysis/reporting
• No tracking for opens/clicks
• Had slight hesitation on some sends

Postmark

• Very cheap, but not as cheap as AuthSMTP
• Beautiful cpanel but no tracking on opens/clicks
• Send-level activity tracking so you can open a single email that was sent and look at how it looked and the delivery data.
• Have to use API. Sending by SMTP was recently introduced but it's buggy. For instance, we noticed that quotes (") in the subject line are stripped.
• Cannot send any attachment you want. Must be on approved list of file types and under a certain size. (10 MB I think)
• Requires a set list of from names/addresses.

JangoSMTP

• Expensive in relation to the others – more than 10 times in some cases
• Ugly cpanel but great tracking on opens/clicks with email-level detail
• Had hesitation, at times, when sending. On two occasions, sends took an hour to be delivered
• Requires a set list of from name/addresses.

SendGrid

• Not quite a cheap as AuthSMTP but still very cheap. Many customers can exist on 200 free sends per day.
• Decent cpanel but no in-depth detail on open/click tracking
• Lots of API options. Options (open/click tracking, etc) can be custom defined on an email-by-email basis. Inbound (reply) email can be posted to our HTTP end point.
• Absolutely zero hesitation on sends. Every email sent landed in the inbox almost immediately.
• Can send from any from name/address.

Conclusion

SendGrid was the best with Postmark coming in second place. We never saw any hesitation in send times with either of those two - in some cases we sent several hundred emails at once - and they both have the best ROI, given a solid featureset.

i'll make an example, first decide what browser you want to emulate, in this case i chose Firefox 60.6.1esr (64-bit), and check what GET request it issues, this can be obtained with a simple netcat server (MacOS bundles netcat, most linux distributions bunles netcat, and Windows users can get netcat from.. Cygwin.org , among other places),

setting up the netcat server to listen on port 9999: nc -l 9999

now hitting http://127.0.0.1:9999 in firefox, i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

now let us compare that with this simple script:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_exec($ch);

i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
Accept: */*

there are several missing headers here, they can all be added with the CURLOPT_HTTPHEADER option of curl_setopt, but the User-Agent specifically should be set with CURLOPT_USERAGENT instead (it will be persistent across multiple calls to curl_exec() and if you use CURLOPT_FOLLOWLOCATION then it will persist across http redirections as well), and the Accept-Encoding header should be set with CURLOPT_ENCODING instead (if they're set with CURLOPT_ENCODING then curl will automatically decompress the response if the server choose to compress it, but if you set it via CURLOPT_HTTPHEADER then you must manually detect and decompress the content yourself, which is a pain in the ass and completely unnecessary, generally speaking) so adding those we get:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

now running that code, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept-Encoding: gzip, deflate
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Connection: keep-alive
Upgrade-Insecure-Requests: 1

and voila! our php-emulated browser GET request should now be indistinguishable from the real firefox GET request :)

this next part is just nitpicking, but if you look very closely, you'll see that the headers are stacked in the wrong order, firefox put the Accept-Encoding header in line 6, and our emulated GET request puts it in line 3.. to fix this, we can manually put the Accept-Encoding header in the right line,

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Accept-Encoding: gzip, deflate',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

running that, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

problem solved, now the headers is even in the correct order, and the request seems to be COMPLETELY INDISTINGUISHABLE from the real firefox request :) (i don't actually recommend this last step, it's a maintenance burden to keep CURLOPT_ENCODING in sync with the custom Accept-Encoding header, and i've never experienced a situation where the order of the headers are significant)

I had the same issue, but reason was different.

In my web.config there was a URL rewrite module rule and I haven’t installed URL rewrite module also. After I install url rewrite module this problem solved.

I'd have to give more thought to a complete solution, but as a handy optimisation, I wonder whether it might be worth pre-computing a table of frequencies of digrams and trigrams (2- and 3-letter combinations) based on all the words from your dictionary, and use this to prioritise your search. I'd go with the starting letters of words. So if your dictionary contained the words "India", "Water", "Extreme", and "Extraordinary", then your pre-computed table might be:

'IN': 1
'WA': 1
'EX': 2

Then search for these digrams in the order of commonality (first EX, then WA/IN)

I had a same problem and the same error was showing up. my TNSNAMES:ORA file was also good to go but apparently there was a problem due to firewall blocking the access. SO a good tip would be to make sure that firewall is not blocking the access to the datasource.

Just use the max function and group function

    select max(taskhistory.id) as id from taskhistory
            group by taskhistory.taskid
            order by taskhistory.datum desc

0 is conditional value when this condition is true, loop will keep executing.10 is the initial value. 1 is the modifier where may be simple decrement.

for number in reversed(range(0,10,1)):
print number;

In [30]: pd.Series([1,2,3,4,'.']).convert_objects(convert_numeric=True)
Out[30]: 
0     1
1     2

Something you can try is using the bind method, I think this achieves what you were asking for. If nothing else, it's still very useful.

function doClick(elem, func) {
  var diffElem = document.getElementById('some_element'); //could be the same or different element than the element in the doClick argument
  diffElem.addEventListener('click', func.bind(diffElem, elem))
}

function clickEvent(elem, evt) {
  console.log(this);
  console.log(elem); 
  // 'this' and elem can be the same thing if the first parameter 
  // of the bind method is the element the event is being attached to from the argument passed to doClick
  console.log(evt);
}

var elem = document.getElementById('elem_to_do_stuff_with');
doClick(elem, clickEvent);

That's the Unicode Replacement Character, \uFFFD. (info)

Something like this should work:

String strImport = "For some reason my ?double quotes? were lost.";
strImport = strImport.replaceAll("\uFFFD", "\"");

Due to a bug in https://bugs.chromium.org/p/chromedriver/issues/detail?id=1465 even though webdriver.switchTo actually does switch tabs, the focus is left on the first tab.

You can confirm this by doing a driver.get after the switchWindow and see that the second tab actually go to the new URL and not the original tab.

A workaround for now is what yardening2 suggested. Use JavaScript code to open an alert and then use webdriver to accept it.

You can use

#pragma GCC push_options
#pragma GCC optimize ("O0")

your code

#pragma GCC pop_options

to disable optimizations since GCC 4.4.

See the GCC documentation if you need more details.

in my case, using asp:Textbox control (Asp.net 4.5), instead of setting the all page for validateRequest="false" i used

<asp:TextBox runat="server" ID="mainTextBox"
            ValidateRequestMode="Disabled"
 ></asp:TextBox>

on the Textbox that caused the exception.

long and long int are identical. So are long long and long long int. In both cases, the int is optional.

As to the difference between the two sets, the C++ standard mandates minimum ranges for each, and that long long is at least as wide as long.

The controlling parts of the standard (C++11, but this has been around for a long time) are, for one, 3.9.1 Fundamental types, section 2 (a later section gives similar rules for the unsigned integral types):

There are five standard signed integer types : signed char, short int, int, long int, and long long int. In this list, each type provides at least as much storage as those preceding it in the list.

There's also a table 9 in 7.1.6.2 Simple type specifiers, which shows the "mappings" of the specifiers to actual types (showing that the int is optional), a section of which is shown below:

Specifier(s)         Type
-------------    -------------
long long int    long long int
long long        long long int
long int         long int
long             long int

Note the distinction there between the specifier and the type. The specifier is how you tell the compiler what the type is but you can use different specifiers to end up at the same type.

Hence long on its own is neither a type nor a modifier as your question posits, it's simply a specifier for the long int type. Ditto for long long being a specifier for the long long int type.

Although the C++ standard itself doesn't specify the minimum ranges of integral types, it does cite C99, in 1.2 Normative references, as applying. Hence the minimal ranges as set out in C99 5.2.4.2.1 Sizes of integer types <limits.h> are applicable.

In terms of long double, that's actually a floating point value rather than an integer. Similarly to the integral types, it's required to have at least as much precision as a double and to provide a superset of values over that type (meaning at least those values, not necessarily more values).

iText has more than one way of doing this. The PdfStamper class is one option. But I find the easiest method is to create a new PDF document then import individual pages from the existing document into the new PDF.

// Create output PDF
Document document = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.getInstance(document, outputStream);
document.open();
PdfContentByte cb = writer.getDirectContent();

// Load existing PDF
PdfReader reader = new PdfReader(templateInputStream);
PdfImportedPage page = writer.getImportedPage(reader, 1); 

// Copy first page of existing PDF into output PDF
document.newPage();
cb.addTemplate(page, 0, 0);

// Add your new data / text here
// for example...
document.add(new Paragraph("my timestamp")); 

document.close();

This will read in a PDF from templateInputStream and write it out to outputStream. These might be file streams or memory streams or whatever suits your application.

This is what i have done to get rid of this error separating variable with "," helped me.

check out my js lib for caching: https://github.com/hoangnd25/cacheJS

My blog post: New way to cache your data with Javascript

Features:

• Conveniently use array as key for saving cache
• Support array and localStorage
• Clear cache by context (clear all blog posts with authorId="abc")
• No dependency

Basic usage:

Saving cache:

cacheJS.set({blogId:1,type:'view'},'<h1>Blog 1</h1>');
cacheJS.set({blogId:2,type:'view'},'<h1>Blog 2</h1>', null, {author:'hoangnd'});
cacheJS.set({blogId:3,type:'view'},'<h1>Blog 3</h1>', 3600, {author:'hoangnd',categoryId:2});

Retrieving cache:

cacheJS.get({blogId: 1,type: 'view'});

Flushing cache

cacheJS.removeByKey({blogId: 1,type: 'view'});
cacheJS.removeByKey({blogId: 2,type: 'view'});

cacheJS.removeByContext({author:'hoangnd'});

Switching provider

cacheJS.use('array');
cacheJS.use('array').set({blogId:1},'<h1>Blog 1</h1>')};

Use the Alert Interface, First switchTo() to alert and then either use accept() to click on OK or use dismiss() to CANCEL it

Alert alert_box = driver.switchTo().alert();
alert_box.accept(); 

or

Alert alert_box = driver.switchTo().alert();
alert_box.dismiss(); 

If you want to add N days to your days. You can use the plus operator as follows -

SELECT ( SYSDATE + N ) FROM DUAL;

I was able to convert pem to crt using this:

openssl x509 -outform der -in your-cert.pem -out your-cert.crt

You are using getData() method as void.

You can not return values from void.

from your question I assume that you already have your data in hdfs. So you don't need to LOAD DATA, which moves the files to the default hive location /user/hive/warehouse. You can simply define the table using the externalkeyword, which leaves the files in place, but creates the table definition in the hive metastore. See here: Create Table DDL eg.:

create external table table_name (
  id int,
  myfields string
)
location '/my/location/in/hdfs';

Please note that the format you use might differ from the default (as mentioned by JigneshRawal in the comments). You can use your own delimiter, for example when using Sqoop:

row format delimited fields terminated by ','

A little late, but if any of you have been going crazy trying to use inline SVG as a background, the escaping suggestions above do not quite work. For one, it does not work in IE, and depending on the content of your SVG the technique will cause trouble in other browsers, like FF.

If you base64 encode the svg (not the entire url, just the svg tag and its contents! ) it works in all browsers. Here is the same jsfiddle example in base64: http://jsfiddle.net/vPA9z/3/

The CSS now looks like this:

body { background-image: 
    url("data:image/svg+xml;base64,PHN2ZyB4bWxucz0naHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmcnIHdpZHRoPScxMCcgaGVpZ2h0PScxMCc+PGxpbmVhckdyYWRpZW50IGlkPSdncmFkaWVudCc+PHN0b3Agb2Zmc2V0PScxMCUnIHN0b3AtY29sb3I9JyNGMDAnLz48c3RvcCBvZmZzZXQ9JzkwJScgc3RvcC1jb2xvcj0nI2ZjYycvPiA8L2xpbmVhckdyYWRpZW50PjxyZWN0IGZpbGw9J3VybCgjZ3JhZGllbnQpJyB4PScwJyB5PScwJyB3aWR0aD0nMTAwJScgaGVpZ2h0PScxMDAlJy8+PC9zdmc+");

Remember to remove any URL escaping before converting to base64. In other words, the above example showed color='#fcc' converted to color='%23fcc', you should go back to #.

The reason why base64 works better is that it eliminates all the issues with single and double quotes and url escaping

If you are using JS, you can use window.btoa() to produce your base64 svg; and if it doesn't work (it might complain about invalid characters in the string), you can simply use https://www.base64encode.org/.

Example to set a div background:

var mySVG = "<svg xmlns='http://www.w3.org/2000/svg' width='10' height='10'><linearGradient id='gradient'><stop offset='10%' stop-color='#F00'/><stop offset='90%' stop-color='#fcc'/> </linearGradient><rect fill='url(#gradient)' x='0' y='0' width='100%' height='100%'/></svg>";_x000D_
var mySVG64 = window.btoa(mySVG);_x000D_
document.getElementById('myDiv').style.backgroundImage = "url('data:image/svg+xml;base64," + mySVG64 + "')";

html, body, #myDiv {_x000D_
  width: 100%;_x000D_
  height: 100%;_x000D_
  margin: 0;_x000D_
}

<div id="myDiv"></div>

With JS you can generate SVGs on the fly, even changing its parameters.

One of the better articles on using SVG is here : http://dbushell.com/2013/02/04/a-primer-to-front-end-svg-hacking/

Hope this helps

Try <input type="number" step="0.01" /> if you are targeting 2 decimal places :-).

You could also use negative margins:

.column {_x000D_
  float: left;_x000D_
  overflow: hidden;_x000D_
  width: 120px;_x000D_
}_x000D_
.cell {_x000D_
  border: 1px solid red;_x000D_
  width: 120px;_x000D_
  height: 20px;_x000D_
  box-sizing: border-box;_x000D_
}_x000D_
.cell:not(:first-child) {_x000D_
  margin-top: -1px;_x000D_
}_x000D_
.column:not(:first-child) > .cell {_x000D_
  margin-left: -1px;_x000D_
}

Commonly used in UIsegmentedControl, "error" appear when compiling in 64bits instead of 32bits, easy way for not pass it to a new variable is to use this tips, add (int):

instead of :

[_monChiffre setUnite:[_valUnites selectedSegmentIndex]];

git revert -m allows to un-merge still keeping the history of both merge and un-do operation. Might be good for documenting probably.

<%=%> by itself will be sent to the output, in the context of the JSTL it will be evaluated to a string

That's because you should pass a function, not a string:

function funcName() {
    alert("test");
}

setInterval(funcName, 10000);

Your code has two problems:

• var func = funcName(); calls the function immediately and assigns the return value.
• Just "func" is invalid even if you use the bad and deprecated eval-like syntax of setInterval. It would be setInterval("func()", 10000) to call the function eval-like.

Debian Linux (e.g. Ubuntu)

sudo apt-get update
OpenGL: sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev

Windows

Locate your Visual Studio folder for where it puts libraries and also header files, download and copy lib files to lib folder and header files to header. Then copy dll files to system32. Then your code will 100% run.

Also Windows: For all of those includes you just need to download glut32.lib, glut.h, glut32.dll.

The suggestion to use .split(/[ ,]+/) is good, but with natural sentences sooner or later you'll end up getting empty elements in the array. e.g. ['foo', '', 'bar'].

Which is fine if that's okay for your use case. But if you want to get rid of the empty elements you can do:

var str = 'whatever your text is...';
str.split(/[ ,]+/).filter(Boolean);

Following Regex validations:

• No spacial characters before @
• (-) and (.) should not be together after @
• No special characters after @ 2 characters must before @

• Email length should be less 128 characters

  function validateEmail(email) {
      var chrbeforAt = email.substr(0, email.indexOf('@'));
      if (!($.trim(email).length > 127)) {
          if (chrbeforAt.length >= 2) {
              var re = /^(([^<>()[\]{}'^?\\.,!|//#%*-+=&;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?/;
              return re.test(email);
          } else {
              return false;
          }
      } else {
          return false;
      }
  }
  

In SQL Server 2008 there are two new Dynamic Management Functions introduced to keep track of object dependencies: sys.dm_sql_referenced_entities and sys.dm_sql_referencing_entities:

1/ Returning the entities that refer to a given entity:

SELECT
        referencing_schema_name, referencing_entity_name, 
        referencing_class_desc, is_caller_dependent
FROM sys.dm_sql_referencing_entities ('<TableName>', 'OBJECT')

2/ Returning entities that are referenced by an object:

SELECT
        referenced_schema_name, referenced_entity_name, referenced_minor_name, 
        referenced_class_desc, is_caller_dependent, is_ambiguous
FROM sys.dm_sql_referenced_entities ('<StoredProcedureName>', 'OBJECT');

Alternatively, you can use sp_depends:

EXEC sp_depends '<TableName>'

Another option is to use a pretty useful tool called SQL Dependency Tracker from Red Gate.

<script type = “text/template”> … </script> is obsolete. Use <template> tag instead.

this keyword use to call constructor in the same class (other overloaded constructor)

syntax: this (args list); //compatible with args list in other constructor in the same class

super keyword use to call constructor in the super class.

syntax: super (args list); //compatible with args list in the constructor of the super class.

Ex:

public class Rect {
int x1, y1, x2, y2;

public Rect(int x1, int y1, int x2, int y2) // 1st constructor 
{ ....//code to build a rectangle }
}

public Rect () {   // 2nd constructor
this (0,0,width,height) // call 1st constructor (because it has **4 int args**), this is another way to build a rectangle 
}


public class DrawableRect extends Rect {

public DrawableRect (int a1, int b1, int a2, int b2) {
super (a1,b1,a2,b2) // call super class constructor (Rect class) 
}
}

I'm assuming you have multiple markers that you wish to display on a google map.

The solution is two parts, one to create and populate an array containing all the details of the markers, then a second to loop through all entries in the array to create each marker.

Not know what environment you're using, it's a little difficult to provide specific help.

My best advice is to take a look at this article & accepted answer to understand the principals of creating a map with multiple markers: Display multiple markers on a map with their own info windows

Try mpstat from the sysstat package

> sudo apt-get install sysstat

Then some cutor grepto parse the info you need:

mpstat | grep -A 5 "%idle" | tail -n 1 | awk -F " " '{print 100 -  $ 12}'a

There is an interesting port of NetworkX to Javascript that might do what you want. See http://felix-kling.de/JSNetworkX/

If you are using GVim, you can also set guioptions+=a. This will trigger automatic copy to clipboard of text that you highlight in visual mode.
Drawback: Note that advanced clipboard managers (with history) will in this case get all your selection history…

Just use:

.getClass().getSimpleName();

Example:

StringBuilder randSB = new StringBuilder("just a String");
System.out.println(randSB.getClass().getSimpleName());

Output:

StringBuilder

This should do the trick.

Requires bootstrap.js.

Example => http://getbootstrap.com/javascript/#collapse

    $('.nav li a').click(function() {
      $('#nav-main').collapse('hide');
    });

This does the same thing as adding 'data-toggle="collapse"' and 'href="yournavigationID"' attributes to navigation menus tags.

There is Number.isInteger(number) to check this. Doesn't work in Internet Explorer but that browser isn't used anymore. If you need string like "90" to be an integer (which wasnt the question) try Number.isInteger(Number(number)). The "official" isInteger considers 9.0 as an integer, see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number. It looks like most answers are correct for older browsers but modern browsers have moved on and actually support float integer check.

Microsoft: "Corrupted process state exceptions are exceptions that indicate that the state of a process has been corrupted. We do not recommend executing your application in this state.....If you are absolutely sure that you want to maintain your handling of these exceptions, you must apply the HandleProcessCorruptedStateExceptionsAttribute attribute"

It's quite simple:

if(new Date(fit_start_time) <= new Date(fit_end_time))
{//compare end <=, not >=
    //your code here
}

Comparing 2 Date instances will work just fine. It'll just call valueOf implicitly, coercing the Date instances to integers, which can be compared using all comparison operators. Well, to be 100% accurate: the Date instances will be coerced to the Number type, since JS doesn't know of integers or floats, they're all signed 64bit IEEE 754 double precision floating point numbers.

Per Truth value testing, 'None' directly tests as FALSE, so the simplest expression will suffice:

PowerShell 3 supports this out of the box now.

If you're stuck on PowerShell 2, you basically have to use the legacy net use command (as suggested earlier).

The command is this:

mysqlcheck -u root -p --auto-repair --check --all-databases

You must supply the password when asked,

or you can run this one but it's not recommended because the password is written in clear text:

mysqlcheck -u root --password=THEPASSWORD --auto-repair --check --all-databases

You'll want to use a number of layout managers to help you achieve the basic results you want.

Check out A Visual Guide to Layout Managers for a comparision.

You could use a GridBagLayout but that's one of the most complex (and powerful) layout managers available in the JDK.

You could use a series of compound layout managers instead.

I'd place the graphics component and text area on a single JPanel, using a BorderLayout, with the graphics component in the CENTER and the text area in the SOUTH position.

I'd place the text field and button on a separate JPanel using a GridBagLayout (because it's the simplest I can think of to achieve the over result you want)

I'd place these two panels onto a third, master, panel, using a BorderLayout, with the first panel in the CENTER and the second at the SOUTH position.

But that's me

typeOf is a C# keyword that is used when you have the name of the class. It is calculated at compile time and thus cannot be used on an instance, which is created at runtime. GetType is a method of the object class that can be used on an instance.

NSTimeInterval milisecondedDate = ([[NSDate date] timeIntervalSince1970] * 1000);

My way of Insert in SQL Server. Also I usually check if a temporary table exists.

IF OBJECT_ID('tempdb..#MyTable') IS NOT NULL DROP Table #MyTable

SELECT b.Val as 'bVals'
  INTO #MyTable
FROM OtherTable as b

CREATE TABLE someTable (
    id serial PRIMARY KEY,
    col1 int NOT NULL,
    col2 int NOT NULL,
    UNIQUE (col1, col2)
)

autoincrement is not postgresql. You want a serial.

If col1 and col2 make a unique and can't be null then they make a good primary key:

CREATE TABLE someTable (
    col1 int NOT NULL,
    col2 int NOT NULL,
    PRIMARY KEY (col1, col2)
)

From the horse's mouth: Explicit line joining

Two or more physical lines may be joined into logical lines using backslash characters (\), as follows: when a physical line ends in a backslash that is not part of a string literal or comment, it is joined with the following forming a single logical line, deleting the backslash and the following end-of-line character. For example:

if 1900 < year < 2100 and 1 <= month <= 12 \
   and 1 <= day <= 31 and 0 <= hour < 24 \
   and 0 <= minute < 60 and 0 <= second < 60:   # Looks like a valid date
        return 1

A line ending in a backslash cannot carry a comment. A backslash does not continue a comment. A backslash does not continue a token except for string literals (i.e., tokens other than string literals cannot be split across physical lines using a backslash). A backslash is illegal elsewhere on a line outside a string literal.

Angular2 v2.1.0 (stable):

The ActivatedRoute provides an observable one can subscribe.

  constructor(
     private route: ActivatedRoute

This triggers everytime the route gets updated, as well: /home/files/123 -> /home/files/321

Done it, by a bit of creative programming,

1. Enum the Keys in HKEY_USERS for those funny number keys...

2. Enum the keys in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\

and you will find the same numbers.... Now in those keys look at the String value: ProfileImagePath = "SomeValue" where the values are either:

"%systemroot%\system32\config\systemprofile"... not interested in this one... as its not a directory path...

%SystemDrive%\Documents and Settings\LocalService - "Local Services" %SystemDrive%\Documents and Settings\NetworkService "NETWORK SERVICE"

or

%SystemDrive%\Documents and Settings\USER_NAME, which translates directly to the "USERNAME" values in most un-tampered systems, ie. where the user has not changed the their user name after a few weeks or altered the paths explicitly...

Using VS 2010:

Let's say you have a Windows.Forms project. You add a UserControl (say MyControl) to the project, and design it all up. Now you want to add it to your toolbox.

As soon as the project is successfully built once, it will appear in your Framework Components. Right click the Toolbox to get the context menu, select "Choose Items...", and browse to the name of your control (MyControl) under the ".NET Framework Components" tab.

Advantage over using dlls: you can edit the controls in the same project as your form, and the form will build with the new controls. However, the control will only be avilable to this project.

Note: If the control has build errors, resolve them before moving on to the containing forms, or the designer has a heart attack.

This function work like a charm

function toggle_full_screen()
{
    if ((document.fullScreenElement && document.fullScreenElement !== null) || (!document.mozFullScreen && !document.webkitIsFullScreen))
    {
        if (document.documentElement.requestFullScreen){
            document.documentElement.requestFullScreen();
        }
        else if (document.documentElement.mozRequestFullScreen){ /* Firefox */
            document.documentElement.mozRequestFullScreen();
        }
        else if (document.documentElement.webkitRequestFullScreen){   /* Chrome, Safari & Opera */
            document.documentElement.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);
        }
        else if (document.msRequestFullscreen){ /* IE/Edge */
            document.documentElement.msRequestFullscreen();
        }
    }
    else
    {
        if (document.cancelFullScreen){
            document.cancelFullScreen();
        }
        else if (document.mozCancelFullScreen){ /* Firefox */
            document.mozCancelFullScreen();
        }
        else if (document.webkitCancelFullScreen){   /* Chrome, Safari and Opera */
            document.webkitCancelFullScreen();
        }
        else if (document.msExitFullscreen){ /* IE/Edge */
            document.msExitFullscreen();
        }
    }
}

To use it just call:

toggle_full_screen();

while u write R. you are referring to the R.java class created by eclipse, use getResources().getString() and pass the id of the resource from which you are trying to read inside the getString() method.

Example : String[] yourStringArray = getResources().getStringArray(R.array.Your_array);

DataSet myDataset = new DataSet();

DataTable customers = myDataset.Tables.Add("Customers");

customers.Columns.Add("Name");
customers.Columns.Add("Age");

customers.Rows.Add("Chris", "25");

//Get data
DataTable myCustomers = myDataset.Tables["Customers"];
DataRow currentRow = null;
for (int i = 0; i < myCustomers.Rows.Count; i++)
{
    currentRow = myCustomers.Rows[i];
    listBox1.Items.Add(string.Format("{0} is {1} YEARS OLD", currentRow["Name"], currentRow["Age"]));    
}

You can use this code :

.row :nth-child(odd){
  background-color:red;
}
.row :nth-child(even){
  background-color:green;
}

The easiest solution is to redirect the standard output. In your python program file use the following:

if __name__ == "__main__":
   sys.stdout = open('file.log', 'w')
   #sys.stdout = open('/dev/null', 'w')
   main()

Any std output (e.g. the output of print 'hi there') will be redirected to file.log or if you uncomment the second line, any output will just be suppressed.

I needed to keep the placeholder alignment so adam's answer was not enough for me.

To solve this I used a small variation that I hope will help some of you too:

- (void) drawPlaceholderInRect:(CGRect)rect {
    //search field placeholder color
    UIColor* color = [UIColor whiteColor];

    [color setFill];
    [self.placeholder drawInRect:rect withFont:self.font lineBreakMode:UILineBreakModeTailTruncation alignment:self.textAlignment];
}

Structs "really" pure aren't supported in Java. E.g., C# supports struct definitions that represent values and can be allocated anytime.

In Java, the unique way to get an approximation of C++ structs

struct Token
{
    TokenType type;
    Stringp stringValue;
    double mathValue;
}

// Instantiation

{
    Token t = new Token;
}

without using a (static buffer or list) is doing something like

var type = /* TokenType */ ;
var stringValue = /* String */ ;
var mathValue = /* double */ ;

So, simply allocate variables or statically define them into a class.

Here is a practical example of Anchor tag with different

Target Attribute

The question mark is the conditional operator. The code means that if f==r then 1 is returned, otherwise, return 0. The code could be rewritten as

int qempty()
{
  if(f==r)
    return 1;
  else
    return 0;
}

which is probably not the cleanest way to do it, but hopefully helps your understanding.

Yes, you can use the native javascript Date() object and its methods.

For instance you can create a function like:

function formatDate(date) {
  var hours = date.getHours();
  var minutes = date.getMinutes();
  var ampm = hours >= 12 ? 'pm' : 'am';
  hours = hours % 12;
  hours = hours ? hours : 12; // the hour '0' should be '12'
  minutes = minutes < 10 ? '0'+minutes : minutes;
  var strTime = hours + ':' + minutes + ' ' + ampm;
  return (date.getMonth()+1) + "/" + date.getDate() + "/" + date.getFullYear() + "  " + strTime;
}

var d = new Date();
var e = formatDate(d);

alert(e);

And display also the am / pm and the correct time.

Remember to use getFullYear() method and not getYear() because it has been deprecated.

I have a simple solution which is working perfectly. The code is not mine, I found it on this link. Here are the steps to follow:

1. Before downloading the image, let’s write a method for saving bitmap into an image file in the internal storage in android. It needs a context, better to use the pass in the application context by getApplicationContext(). This method can be dumped into your Activity class or other util classes.

    FileOutputStream foStream;
    try

        foStream.close();
    } 
    catch (Exception e) 
    {
        Log.d("saveImage", "Exception 2, Something went wrong!");
        e.printStackTrace();
    }
}

2. Now we have a method to save bitmap into an image file in andorid, let’s write the AsyncTask for downloading images by url. This private class need to be placed in your Activity class as a subclass. After the image is downloaded, in the onPostExecute method, it calls the saveImage method defined above to save the image. Note, the image name is hardcoded as “my_image.png”.

private class DownloadImage extends AsyncTask<String, Void, Bitmap> {
    private String TAG = "DownloadImage";
    private Bitmap downloadImageBitmap(String sUrl) {
        Bitmap bitmap = null;
        try {
            InputStream inputStream = new URL(sUrl).openStream();   // Download Image from URL
            bitmap = BitmapFactory.decodeStream(inputStream);       // Decode Bitmap
            inputStream.close();
        } catch (Exception e) {
            Log.d(TAG, "Exception 1, Something went wrong!");
            e.printStackTrace();
        }
        return bitmap;
    }

    @Override
    protected Bitmap doInBackground(String... params) {
        return downloadImageBitmap(params[0]);
    }

    protected void onPostExecute(Bitmap result) {
        saveImage(getApplicationContext(), result, "my_image.png");
    }
}

3. The AsyncTask for downloading the image is defined, but we need to execute it in order to run that AsyncTask. To do so, write this line in your onCreate method in your Activity class, or in an onClick method of a button or other places you see fit.

new DownloadImage().execute("http://developer.android.com/images/activity_lifecycle.png");

The image should be saved in /data/data/your.app.packagename/files/my_image.jpeg, check this post for accessing this directory from your device.

IMO this solves the issue! If you want further steps such as load the image you can follow these extra steps:

4. After the image is downloaded, we need a way to load the image bitmap from the internal storage, so we can use it. Let’s write the method for loading the image bitmap. This method takes two paramethers, a context and an image file name, without the full path, the context.openFileInput(imageName) will look up the file at the save directory when this file name was saved in the above saveImage method.

public Bitmap loadImageBitmap(Context context, String imageName) {
    Bitmap bitmap = null;
    FileInputStream fiStream;
    try {
        fiStream    = context.openFileInput(imageName);
        bitmap      = BitmapFactory.decodeStream(fiStream);
        fiStream.close();
    } catch (Exception e) {
        Log.d("saveImage", "Exception 3, Something went wrong!");
        e.printStackTrace();
    }
    return bitmap;
}

5. Now we have everything we needed for setting the image of an ImageView or any other Views that you like to use the image on. When we save the image, we hardcoded the image name as “my_image.jpeg”, now we can pass this image name to the above loadImageBitmap method to get the bitmap and set it to an ImageView.

someImageView.setImageBitmap(loadImageBitmap(getApplicationContext(), "my_image.jpeg"));

6. To get the image full path by image name.

File file            = getApplicationContext().getFileStreamPath("my_image.jpeg");
String imageFullPath = file.getAbsolutePath();

7. Check if the image file exists.

File file =

getApplicationContext().getFileStreamPath("my_image.jpeg");
if (file.exists()) Log.d("file", "my_image.jpeg exists!");

8. To delete the image file.

   File file = getApplicationContext().getFileStreamPath("my_image.jpeg"); if (file.delete()) Log.d("file", "my_image.jpeg deleted!");

Answers by ‘smartnut007’, ‘Bill Karwin’, and ‘sqlvogel’ are excellent. Yet let me put an interesting perspective to it.

Well, we have prime and non-prime keys.

When we focus on how non-primes depend on primes, we see two cases:

Non-primes can be dependent or not.

• When dependent: we see they must depend on a full candidate key. This is 2NF.

• When not dependent: there can be no-dependency or transitive dependency

  • Not even transitive dependency: Not sure what normalization theory addresses this.
  • When transitively dependent: It is deemed undesirable. This is 3NF.

What about dependencies among primes?

Now you see, we’re not addressing the dependency relationship among primes by either 2nd or 3rd NF. Further such dependency, if any, is not desirable and thus we’ve a single rule to address that. This is BCNF.

Referring to the example from Bill Karwin's post here, you’ll notice that both ‘Topping’, and ‘Topping Type’ are prime keys and have a dependency. Had they been non-primes with dependency, then 3NF would have kicked in.

Note:

The definition of BCNF is very generic and without differentiating attributes between prime and non-prime. Yet, the above way of thinking helps to understand how some anomaly is percolated even after 2nd and 3rd NF.

Advanced Topic: Mapping generic BCNF to 2NF & 3NF

Now that we know BCNF provides a generic definition without reference to any prime/non-prime attribues, let's see how BCNF and 2/3 NF's are related.

First, BCNF requires (other than the trivial case) that for each functional dependency X -> Y (FD), X should be super-key. If you just consider any FD, then we've three cases - (1) Both X and Y non-prime, (2) Both prime and (3) X prime and Y non-prime, discarding the (nonsensical) case X non-prime and Y prime.

For case (1), 3NF takes care of.

For case (3), 2NF takes care of.

For case (2), we find the use of BCNF

You can also look at filever.exe, which can be downloaded as part of the Windows XP SP2 Support Tools package - only 4.7MB of download.

Try running

lsof | grep /mnt/data

That should list any process that is accessing /mnt/data that would prevent it from being unmounted.

I know this isn't a direct answer to your question, but you could also consider using clip-path, as in this question: https://stackoverflow.com/a/18208889/23341.

I found another solution for new Sonar versions where JaCoCo's binary report format (*.exec) was deprecated and the preferred format is XML (SonarJava 5.12 and higher). The solution is very simple and similar to the previous solution with *.exec reports in parent directory from this topic: https://stackoverflow.com/a/15535970/4448263.

Assuming that our project structure is:

moduleC - aggregate project's pom
  |- moduleA - some classes without tests
  |- moduleB - some classes depending from moduleA and tests for classes in both modules: moduleA and moduleB

You need following maven build plugin configuration in aggregate project's pom:

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>0.8.5</version>
    <executions>
        <execution>
            <id>prepare-and-report</id>
            <goals>
                <goal>prepare-agent</goal>
                <goal>report</goal>
            </goals>
        </execution>
        <execution>
            <id>report-aggregate</id>
            <phase>verify</phase>
            <goals>
                <goal>report-aggregate</goal>
            </goals>
            <configuration>
                <outputDirectory>${project.basedir}/../target/site/jacoco-aggregate</outputDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>

Then build project with maven:

mvn clean verify

And for Sonar you should set property in administration GUI:

sonar.coverage.jacoco.xmlReportPaths=target/site/jacoco/jacoco.xml,../target/site/jacoco-aggregate/jacoco.xml

or using command line:

mvn sonar:sonar -Dsonar.coverage.jacoco.xmlReportPaths=target/site/jacoco/jacoco.xml,../target/site/jacoco-aggregate/jacoco.xml

Description

This creates binary reports for each module in default directories: target/jacoco.exec. Then creates XML reports for each module in default directories: target/site/jacoco/jacoco.xml. Then creates an aggregate report for each module in custom directory ${project.basedir}/../target/site/jacoco-aggregate/ that is relative to parent directory for each module. For moduleA and moduleB this will be common path moduleC/target/site/jacoco-aggregate/.

As moduleB depends on moduleA, moduleB will be built last and its report will be used as an aggregate coverage report in Sonar for both modules A and B.

In addition to the aggregate report, we need a normal module report as JaCoCo aggregate reports contain coverage data only for dependencies.

Together, these two types of reports providing full coverage data for Sonar.

There is one little restriction: you should be able to write a report in the project's parent directory (should have permission). Or you can set property jacoco.skip=true in root project's pom.xml (moduleC) and jacoco.skip=false in modules with classes and tests (moduleA and moduleB).

For Mac + Android Studio 2.1, I found the best way is to save the image and then copy (cmd + c) the image file in Finder and then click on the the drawable directory and cmd + v to paste in that directory. Copying the image directly from a website using cmd + c (or right click then copy) doesn't seem to work.

This should get you access to applicationContext from anywhere allowing you to get applicationContext anywhere that can use it; Toast, getString(), sharedPreferences, etc.

The Singleton:

package com.domain.packagename;

import android.content.Context;

/**
 * Created by Versa on 10.09.15.
 */
public class ApplicationContextSingleton {
    private static PrefsContextSingleton mInstance;
    private Context context;

    public static ApplicationContextSingleton getInstance() {
        if (mInstance == null) mInstance = getSync();
        return mInstance;
    }

    private static synchronized ApplicationContextSingleton getSync() {
        if (mInstance == null) mInstance = new PrefsContextSingleton();
        return mInstance;
    }

    public void initialize(Context context) {
        this.context = context;
    }

    public Context getApplicationContext() {
        return context;
    }

}

Initialize the Singleton in your Application subclass:

package com.domain.packagename;

import android.app.Application;

/**
 * Created by Versa on 25.08.15.
 */
public class mApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        ApplicationContextSingleton.getInstance().initialize(this);
    }
}

If I´m not wrong, this gives you a hook to applicationContext everywhere, call it with ApplicationContextSingleton.getInstance.getApplicationContext(); You shouldn´t need to clear this at any point, as when application closes, this goes with it anyway.

Remember to update AndroidManifest.xml to use this Application subclass:

<?xml version="1.0" encoding="utf-8"?>

<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.domain.packagename"
    >

<application
    android:allowBackup="true"
    android:name=".mApplication" <!-- This is the important line -->
    android:label="@string/app_name"
    android:theme="@style/AppTheme"
    android:icon="@drawable/app_icon"
    >

Please let me know if you see anything wrong here, thank you. :)

SOLUTION!

just set -config parameter location correctly, i.e :

openssl ....................  -config C:\bin\apache\apache2.4.9\conf\openssl.cnf

CustomAdapter mAdapter = new CustomAdapter( getApplicationContext(), yourlist);

or

Context mContext = getAppliactionContext();
CustomAdapter mAdapter = new CustomAdapter( mContext, yourlist);

change to below

CustomAdapter mAdapter = new CustomAdapter( this, yourlist);

If you git clone some project then this kind of issue may usually occur.

1. make sure there is .env file
2. run php artisan key:generate and then it should generate APP_KEY in .env
3. finally run php artisan serve and it should be working.

C also does a good job at not making anything ambiguous.

Sure the dot could be overloaded to mean both things, but the arrow makes sure that the programmer knows that he's operating on a pointer, just like when the compiler won't let you mix two incompatible types.

Depending whether or not you know the image format, here are ways you can do it :

Download Image to a file, knowing the image format

using (WebClient webClient = new WebClient()) 
{
   webClient.DownloadFile("http://yoururl.com/image.png", "image.png") ; 
}

Download Image to a file without knowing the image format

You can use Image.FromStream to load any kind of usual bitmaps (jpg, png, bmp, gif, ... ), it will detect automaticaly the file type and you don't even need to check the url extension (which is not a very good practice). E.g:

using (WebClient webClient = new WebClient()) 
{
    byte [] data = webClient.DownloadData("https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-xpf1/v/t34.0-12/10555140_10201501435212873_1318258071_n.jpg?oh=97ebc03895b7acee9aebbde7d6b002bf&oe=53C9ABB0&__gda__=1405685729_110e04e71d9");

   using (MemoryStream mem = new MemoryStream(data)) 
   {
       using (var yourImage = Image.FromStream(mem)) 
       { 
          // If you want it as Png
           yourImage.Save("path_to_your_file.png", ImageFormat.Png) ; 

          // If you want it as Jpeg
           yourImage.Save("path_to_your_file.jpg", ImageFormat.Jpeg) ; 
       }
   } 

}

Note : ArgumentException may be thrown by Image.FromStream if the downloaded content is not a known image type.

Check this reference on MSDN to find all format available. Here are reference to WebClient and Bitmap.

For text:

[RangeObject].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

For cell background

[RangeObject].Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

ExecuteScalar returns the first column of the first row. Other columns or rows are ignored. It looks like your first column of the first row is null, and that's why you get NullReferenceException when you try to use the ExecuteScalar method.

From MSDN;

Return Value

The first column of the first row in the result set, or a null reference if the result set is empty.

You might need to use COUNT in your statement instead which returns the number of rows affected...

Using parameterized queries is always a good practise. It prevents SQL Injection attacks.

And Table is a reserved keyword in T-SQL. You should use it with square brackets, like [Table] also.

As a final suggestion, use the using statement for dispose your SqlConnection and SqlCommand:

SqlCommand check_User_Name = new SqlCommand("SELECT COUNT(*) FROM [Table] WHERE ([user] = @user)" , conn);
check_User_Name.Parameters.AddWithValue("@user", txtBox_UserName.Text);
int UserExist = (int)check_User_Name.ExecuteScalar();

if(UserExist > 0)
{
   //Username exist
}
else
{
   //Username doesn't exist.
}

The best answer according to the Python programming FAQ would be:

functions = {'myfoo': foo.bar}

mystring = 'myfoo'
if mystring in functions:
    functions[mystring]()

The primary advantage of this technique is that the strings do not need to match the names of the functions. This is also the primary technique used to emulate a case construct

Like this:

int main()
{
    int arr[2][5] =
    {
        {1,8,12,20,25},
        {5,9,13,24,26}
    };
}

This should be covered by your C++ textbook: which one are you using?

Anyway, better, consider using std::vector or some ready-made matrix class e.g. from Boost.

As of InteliJ IDEA 2017.2.5, you can change the editor font size by going to:

Settings ? Editor ? Font

I use the following code snippets for encoding (assuming fileName contains the filename and extension of the file, i.e.: test.txt):

PHP:

if ( strpos ( $_SERVER [ 'HTTP_USER_AGENT' ], "MSIE" ) > 0 )
{
     header ( 'Content-Disposition: attachment; filename="' . rawurlencode ( $fileName ) . '"' );
}
else
{
     header( 'Content-Disposition: attachment; filename*=UTF-8\'\'' . rawurlencode ( $fileName ) );
}

Java:

fileName = request.getHeader ( "user-agent" ).contains ( "MSIE" ) ? URLEncoder.encode ( fileName, "utf-8") : MimeUtility.encodeWord ( fileName );
response.setHeader ( "Content-disposition", "attachment; filename=\"" + fileName + "\"");

Anything if you use directly in the Codeigniter framework directly, like base_url(), uri_string(), or word_limiter(), All of these are coming from some sort of Helper function of framework.

While some of Helpers may be available globally to use just like log_message() which are extremely useful everywhere, rest of the Helpers are optional and use case varies application to application. base_url() is a function defined in url helper of the Framework.

You can learn more about helper in Codeigniter user guide's helper section.

You can use base_url() function once your current class have access to it, for which you needs to load it first.

$this->load->helper('url')

You can use this line anywhere in the application before using the base_url() function.

If you need to use it frequently, I will suggest adding this function in config/autoload.php in the autoload helpers section.

Also, make sure you have well defined base_url value in your config/config.php file.

This will be the first configuration you will see,

$config['base_url'] = 'http://yourdomain.com/'; 

You can check quickly by

echo base_url();

Reference: https://codeigniter.com/user_guide/helpers/url_helper.html

As a one liner:

ImageIO.write(Scalr.resize(ImageIO.read(...), 150));

# Method 1
f = open("Path/To/Your/File.txt", "w")   # 'r' for reading and 'w' for writing
f.write("Hello World from " + f.name)    # Write inside file 
f.close()                                # Close file 

# Method 2
with open("Path/To/Your/File.txt", "w") as f:   # Opens file and casts as f 
    f.write("Hello World form " + f.name)       # Writing
    # File closed automatically

There are many more methods but these two are most common. Hope this helped!

With the Material Components library you can use the CircularProgressIndicator:

Something like:

<com.google.android.material.progressindicator.CircularProgressIndicator
      android:indeterminate="true"          
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      app:indicatorColor="@array/progress_colors"
      app:indicatorSize="xxdp"
      app:showAnimationBehavior="inward"/>

where array/progress_colors is an array with the colors:

  <integer-array name="progress_colors">
    <item>@color/yellow_500</item>
    <item>@color/blue_700</item>
    <item>@color/red_500</item>
  </integer-array>

Note: it requires at least the version 1.3.0

Use String.valueOf(integer).

It returns a string representation of integer.

Turn off the JavaScript Validator in the "Builders" config for your project:

1. Right click your project
2. Select Properties -> Builders
3. Uncheck the "JavaScript Validator"

Then either restart your Eclipse or/and rename the .js to something like .js_ then back again.

For SQL Server 2005 upwards:

SELECT [name] AS [TableName], [create_date] AS [CreatedDate] FROM sys.tables

For SQL Server 2000 upwards:

SELECT so.[name] AS [TableName], so.[crdate] AS [CreatedDate]
FROM INFORMATION_SCHEMA.TABLES AS it, sysobjects AS so 
WHERE it.[TABLE_NAME] = so.[name]

I finally realized now that instead of

git fetch --all && git reset --hard origin/master

it should be

git fetch --all && git reset --hard origin/<branch_name>

instead (if one works on a different branch)

try this

String[] projection = { MediaStore.Images.Media.DATA };
            @SuppressWarnings("deprecation")
            Cursor cursor = managedQuery(mCapturedImageURI, projection,
                    null, null, null);
            int column_index_data = cursor
                    .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
            cursor.moveToFirst();
            image_path = cursor.getString(column_index_data);
            Log.e("path of image from CAMERA......******************.........",
                    image_path + "");

for capturing image:

    String fileName = "temp.jpg";
    ContentValues values = new ContentValues();
    values.put(MediaStore.Images.Media.TITLE, fileName);
    mCapturedImageURI = getContentResolver().insert(
            MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI);
    values.clear();

This is simple question, and should have a simpler answer than what I see above.

To see the installed npm packages with their version, the command is npm ls --depth=0, which, by default, displays what is installed locally. To see the globally installed packages, add the -global argument: npm ls --depth=0 -global.

--depth=0 returns a list of installed packages without their dependencies, which is what you're wanting to do most of the time.

ls is the name of the command, and list is an alias for ls.

If you are using lodash, its even simpler with takeRight.

_.takeRight(arr, 5);

When you make the call to gcc it should say

g++ -Wall -I/home/alwin/Development/Calculator/ -L/opt/lib main.cpp -lcalc -o calculator

not -libcalc.so 

I have a similar problem with auto-generated makes.

You can create a soft link from your compile directory to the library directory. Then the library becomes "local".

cd /compile/directory

ln -s  /path/to/libcalc.so libcalc.so

because you have initiated the Transaction over the data insertion so, The first check the transaction completed or not. once you start the transaction, it should be committed or rollback according to the status of the transaction;

function add_post($post_data){
  $this->db->trans_begin() 
  $this->db->insert('posts',$post_data);
  $this->db->trans_complete();
  if ($this->db->trans_status() === FALSE){
    $this->db->trans_rollback();
    return 0;
  }else{
    $this->db->trans_commit();
    return $this->db->insert_id();
  }
}``

in the above, we have committed the data on the successful transaction even you get the timestamp

Easiest way is to use System.Linq as previously described

using System.Linq;

public int GetHighestValue(List<MyTypes> list)
{
    return list.Count > 0 ? list.Max(t => t.Age) : 0; //could also return -1
}

This is also possible with a Dictionary

using System.Linq;

public int GetHighestValue(Dictionary<MyTypes, OtherType> obj)
{
    return obj.Count > 0 ? obj.Max(t => t.Key.Age) : 0; //could also return -1
}

check boxlist selected values with seperator

 string items = string.Empty;
        foreach (ListItem i in CheckBoxList1.Items)
        {
            if (i.Selected == true)
            {
                items += i.Text + ",";
            }
        }
        Response.Write("selected items"+ items);

Place mysql-connector-java-5.1.6-bin.jar to the \Apache Tomcat 6.0.18\lib folder. Your problem will be solved.

HAVING: is used to check conditions after the aggregation takes place.
WHERE: is used to check conditions before the aggregation takes place.

This code:

select City, CNT=Count(1)
From Address
Where State = 'MA'
Group By City

Gives you a table of all cities in MA and the number of addresses in each city.

This code:

select City, CNT=Count(1)
From Address
Where State = 'MA'
Group By City
Having Count(1)>5

Gives you a table of cities in MA with more than 5 addresses and the number of addresses in each city.

The error occurs when your repository does not have the default branch set for the remote. You can use the git remote set-head command to modify the default branch, and thus be able to use the remote name instead of a specified branch in that remote.

To query the remote (in this case origin) for its HEAD (typically master), and set that as the default branch:

$ git remote set-head origin --auto

If you want to use a different default remote branch locally, you can specify that branch:

$ git remote set-head origin new-default

Once the default branch is set, you can use just the remote name in git rebase <remote> and any other commands instead of explicit <remote>/<branch>.

Behind the scenes, this command updates the reference in .git/refs/remotes/origin/HEAD.

$ cat .git/refs/remotes/origin/HEAD 
ref: refs/remotes/origin/master

See the git-remote man page for further details.

f = 0.5
a = 0
b = 9
d = [x * f for x in range(a, b)]

would be a way to do it.

Yet another solution.

Add ErrorControllers or static page to with 404 error information.

Modify your web.config (in case of controller).

<system.web>
    <customErrors mode="On" >
       <error statusCode="404" redirect="~/Errors/Error404" />
    </customErrors>
</system.web>

Or in case of static page

<system.web>
    <customErrors mode="On" >
        <error statusCode="404" redirect="~/Static404.html" />
    </customErrors>
</system.web>

This will handle both missed routes and missed actions.

2. Make sure that MTP is selected

Now we can easily do this using the aspect-ratio ^ref property

.container {
  display: grid;
  grid-template-columns: repeat(3, minmax(0, 1fr)); /* 3 columns */
  grid-gap: 10px;
}

.container>* {
  aspect-ratio: 1 / 1; /* a square ratio */
  border: 1px solid;
  
  /* center content */
  display: flex;
  align-items: center;
  justify-content: center;
  text-align: center;
}

img {
  max-width: 100%;
  display: block;
}

<div class="container">
  <div> some content here </div>
  <div><img src="https://picsum.photos/id/25/400/400"></div>
  <div>
    <h1>a title</h1>
  </div>
  <div>more and more content <br>here</div>
  <div>
    <h2>another title</h2>
  </div>
  <div><img src="https://picsum.photos/id/104/400/400"></div>
</div>

Also like below where we can have a variable number of columns

.container {
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(250px, 1fr));
  grid-gap: 10px;
}

.container>* {
  aspect-ratio: 1 / 1; /* a square ratio */
  border: 1px solid;
  
  /* center content */
  display: flex;
  align-items: center;
  justify-content: center;
  text-align: center;
}

img {
  max-width: 100%;
  display: block;
}

<div class="container">
  <div> some content here </div>
  <div><img src="https://picsum.photos/id/25/400/400"></div>
  <div>
    <h1>a title</h1>
  </div>
  <div>more and more content <br>here</div>
  <div>
    <h2>another title</h2>
  </div>
  <div><img src="https://picsum.photos/id/104/400/400"></div>
  <div>more and more content <br>here</div>
  <div>
    <h2>another title</h2>
  </div>
  <div><img src="https://picsum.photos/id/104/400/400"></div>
</div>

Instead of using align-self: center use align-items: center.

There's no need to change flex-direction or use text-align.

Here's your code, with one adjustment, to make it all work:

ul {
  height: 100%;
}

li {
  display: flex;
  justify-content: center;
  /* align-self: center;    <---- REMOVE */
  align-items: center;   /* <---- NEW    */
  background: silver;
  width: 100%;
  height: 20%; 
}

The align-self property applies to flex items. Except your li is not a flex item because its parent – the ul – does not have display: flex or display: inline-flex applied.

Therefore, the ul is not a flex container, the li is not a flex item, and align-self has no effect.

The align-items property is similar to align-self, except it applies to flex containers.

Since the li is a flex container, align-items can be used to vertically center the child elements.

* {_x000D_
  padding: 0;_x000D_
  margin: 0;_x000D_
}_x000D_
html, body {_x000D_
  height: 100%;_x000D_
}_x000D_
ul {_x000D_
  height: 100%;_x000D_
}_x000D_
li {_x000D_
  display: flex;_x000D_
  justify-content: center;_x000D_
  /* align-self: center; */_x000D_
  align-items: center;_x000D_
  background: silver;_x000D_
  width: 100%;_x000D_
  height: 20%;_x000D_
}

<ul>_x000D_
  <li>This is the text</li>_x000D_
</ul>

codepen demo

Technically, here's how align-items and align-self work...

The align-items property (on the container) sets the default value of align-self (on the items). Therefore, align-items: center means all flex items will be set to align-self: center.

But you can override this default by adjusting the align-self on individual items.

For example, you may want equal height columns, so the container is set to align-items: stretch. However, one item must be pinned to the top, so it is set to align-self: flex-start.

example

How is the text a flex item?

Some people may be wondering how a run of text...

<li>This is the text</li>

is a child element of the li.

The reason is that text that is not explicitly wrapped by an inline-level element is algorithmically wrapped by an inline box. This makes it an anonymous inline element and child of the parent.

From the CSS spec:

9.2.2.1 Anonymous inline boxes

Any text that is directly contained inside a block container element must be treated as an anonymous inline element.

The flexbox specification provides for similar behavior.

4. Flex Items

Each in-flow child of a flex container becomes a flex item, and each contiguous run of text that is directly contained inside a flex container is wrapped in an anonymous flex item.

Hence, the text in the li is a flex item.

ls whateveryouwant | xargs -n 1 basename

Does that work for you?

Otherwise you can (cd /the/directory && ls) (yes, parentheses intended)

Raymond's answer is great for python2 (though, you don't need the abs() nor the parens around 10 ** 8). However, for python3, there are important caveats. First, you'll need to make sure you are passing an encoded string. These days, in most circumstances, it's probably also better to shy away from sha-1 and use something like sha-256, instead. So, the hashlib approach would be:

>>> import hashlib
>>> s = 'your string'
>>> int(hashlib.sha256(s.encode('utf-8')).hexdigest(), 16) % 10**8
80262417

If you want to use the hash() function instead, the important caveat is that, unlike in Python 2.x, in Python 3.x, the result of hash() will only be consistent within a process, not across python invocations. See here:

$ python -V
Python 2.7.5
$ python -c 'print(hash("foo"))'
-4177197833195190597
$ python -c 'print(hash("foo"))'
-4177197833195190597

$ python3 -V
Python 3.4.2
$ python3 -c 'print(hash("foo"))'
5790391865899772265
$ python3 -c 'print(hash("foo"))'
-8152690834165248934

This means the hash()-based solution suggested, which can be shortened to just:

hash(s) % 10**8

will only return the same value within a given script run:

#Python 2:
$ python2 -c 's="your string"; print(hash(s) % 10**8)'
52304543
$ python2 -c 's="your string"; print(hash(s) % 10**8)'
52304543

#Python 3:
$ python3 -c 's="your string"; print(hash(s) % 10**8)'
12954124
$ python3 -c 's="your string"; print(hash(s) % 10**8)'
32065451

So, depending on if this matters in your application (it did in mine), you'll probably want to stick to the hashlib-based approach.

Try with:

$row = mysqli_fetch_assoc($result);
echo "my result <a href='data/" . htmlentities($row['classtype'], ENT_QUOTES, 'UTF-8') . ".php'>My account</a>";

If you use default workspace in Jenkins, this might occur. Use custom workspace location without any spaces.

 Try this:- SELECT Case WHEN COLUMNNAME=0 THEN 'sex'
              ELSE WHEN COLUMNNAME=1 THEN 'Female' END AS YOURGRIDCOLUMNNAME FROM YOURTABLENAME

in your query for only true or false column

Add an attribute colspan (abbriviation for 'column span') in your top cell (<td>) and set its value to 2. Your table should resembles the following;

<table>
    <tr>
        <td colspan = "2">
            <!-- Merged Columns -->
        </td>
    </tr>

    <tr>
        <td>
            <!-- Column 1 -->
        </td>

        <td>
            <!-- Column 2 -->
        </td>
    </tr>
</table>

Be careful when you take the exception object or the traceback object out of the exception handler, since this causes circular references and gc.collect() will fail to collect. This appears to be of a particular problem in the ipython/jupyter notebook environment where the traceback object doesn't get cleared at the right time and even an explicit call to gc.collect() in finally section does nothing. And that's a huge problem if you have some huge objects that don't get their memory reclaimed because of that (e.g. CUDA out of memory exceptions that w/o this solution require a complete kernel restart to recover).

In general if you want to save the traceback object, you need to clear it from references to locals(), like so:

import sys, traceback, gc
type, val, tb = None, None, None
try:
    myfunc()
except:
    type, val, tb = sys.exc_info()
    traceback.clear_frames(tb)
# some cleanup code
gc.collect()
# and then use the tb:
if tb:
    raise type(val).with_traceback(tb)

In the case of jupyter notebook, you have to do that at the very least inside the exception handler:

try:
    myfunc()
except:
    type, val, tb = sys.exc_info()
    traceback.clear_frames(tb)
    raise type(val).with_traceback(tb)
finally:
    # cleanup code in here
    gc.collect()

Tested with python 3.7.

p.s. the problem with ipython or jupyter notebook env is that it has %tb magic which saves the traceback and makes it available at any point later. And as a result any locals() in all frames participating in the traceback will not be freed until the notebook exits or another exception will overwrite the previously stored backtrace. This is very problematic. It should not store the traceback w/o cleaning its frames. Fix submitted here.

As Jon has the implementation details answer an other possible answer would be that the JVM doesn't want to handle write in record that have ended his activation.

Consider the use case where your lambdas instead of being apply, is stored in some place and run later.

I remember that in Smalltalk you would get an illegal store raised when you do such modification.

If we are directly use data from csv it will give combine data based on comma separation value as it is .csv file.

user1 = pd.read_csv('dataset/1.csv')

If you want to add column names using pandas, you have to do something like this. But below code will not show separate header for your columns.

col_names=['TIME', 'X', 'Y', 'Z'] 
user1 = pd.read_csv('dataset/1.csv', names=col_names)

To solve above problem we have to add extra filled which is supported by pandas, It is header=None

user1 = pd.read_csv('dataset/1.csv', names=col_names, header=None)

Actually it would have been the same for any object for that matter i.e. being a reference type and passing by reference are 2 different things in c#.

This would work, but that applies regardless of the type:

public static void TestI(ref string test)

Also about string being a reference type, its also a special one. Its designed to be immutable, so all of its methods won't modify the instance (they return a new one). It also has some extra things in it for performance.

It is very simple, just add a property:

public string Value {
  get { return textBox1.Text; }
  set { textBox1.Text = value; }
}

Using the Text property is a bit trickier, the UserControl class intentionally hides it. You'll need to override the attributes to put it back in working order:

[Browsable(true), EditorBrowsable(EditorBrowsableState.Always), Bindable(true)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
public override string Text {
  get { return textBox1.Text; }
  set { textBox1.Text = value; }
}

$regkeypath= "HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" 
$value1 = (Get-ItemProperty $regkeypath -ErrorAction SilentlyContinue).Zoiper -eq $null 
If ($value1 -eq $False) {
Write-Host "Value Exist"
} Else {
Write-Host "The value does not exist"
}

I do this:

html {
    margin-left: calc(100vw - 100%);
    margin-right: 0;
}

Then I don't have to look at the ugly greyed out scrollbar when it's not needed.

Use of pseudo-element as suggested by Terry has one PRO and one CON:

1. PRO - great cross-browser compatibility because pseudo-element are supported also on older IE.
2. CON - it requires to create an extra (even if generated) element, that infact is defined pseudo-element.

Anyway is a great solution.

OTHER SOLUTIONS:

If you can accept compatibility since IE9 (IE8 does not have support for this), you can achieve desired result in other two possible ways:

1. using outline property combined with border and a single inset box-shadow
2. using two box-shadow combined with border.

Here a jsFiddle with Terry's modified code that shows, side by side, these other possible solutions. Main specific properties for each one are the following (others are shared in .double-border class):

.left
{
  outline: 4px solid #fff;
  box-shadow:inset 0 0 0 4px #fff;
}

.right
{
  box-shadow:0 0 0 4px #fff, inset 0 0 0 4px #fff;
}

LESS code:

You asked for possible advantages about using a pre-processor like LESS. I this specific case, utility is not so great, but anyway you could optimize something, declaring colors and border/ouline/shadow with @variable.

Here an example of my CSS code, declared in LESS (changing colors and border-width becomes very quick):

@double-border-size:4px;
@inset-border-color:#fff;
@content-color:#ccc;

.double-border 
{
  background-color: @content-color;
  border: @double-border-size solid @content-color;
  padding: 2em;
  width: 16em;
  height: 16em;
  float:left;
  margin-right:20px;
  text-align:center;
}

.left
{
  outline: @double-border-size solid @inset-border-color;
  box-shadow:inset 0 0 0 @double-border-size @inset-border-color;
}

.right
{
  box-shadow:0 0 0 @double-border-size @inset-border-color, inset 0 0 0 @double-border-size @inset-border-color;
}

Technically, the way you have it worded, neither is correct, because the SOAP method's communication isn't secure, and the REST method didn't say anything about authenticating legitimate users.

HTTPS prevents attackers from eavesdropping on the communication between two systems. It also verifies that the host system (server) is actually the host system the user intends to access.

WS-Security prevents unauthorized applications (users) from accessing the system.

If a RESTful system has a way of authenticating users and a SOAP application with WS-Security is using HTTPS, then really both are secure. It's just a different way of presenting and accessing data.

If you create your test classes in a seperate folder which you then add to your build path,

Then you could make the test class an inner class of the class under test by using package correctly to set the namespace. This gives it access to private fields and methods.

But dont forget to remove the folder from the build path for your release build.

Why not update the files on the local file system instead? You can read/write files into your applications sandboxed area.

The first option in @Nathan Skerl's list is what was implemented in a project I once worked with, where a similar relationship was established between three tables. (One of them referenced two others, one at a time.)

So, the referencing table had two foreign key columns, and also it had a constraint to guarantee that exactly one table (not both, not neither) was referenced by a single row.

Here's how it could look when applied to your tables:

CREATE TABLE dbo.[Group]
(
    ID int NOT NULL CONSTRAINT PK_Group PRIMARY KEY,
    Name varchar(50) NOT NULL
);

CREATE TABLE dbo.[User]
(
    ID int NOT NULL CONSTRAINT PK_User PRIMARY KEY,
    Name varchar(50) NOT NULL
);

CREATE TABLE dbo.Ticket
(
    ID int NOT NULL CONSTRAINT PK_Ticket PRIMARY KEY,
    OwnerGroup int NULL
      CONSTRAINT FK_Ticket_Group FOREIGN KEY REFERENCES dbo.[Group] (ID),
    OwnerUser int NULL
      CONSTRAINT FK_Ticket_User  FOREIGN KEY REFERENCES dbo.[User]  (ID),
    Subject varchar(50) NULL,
    CONSTRAINT CK_Ticket_GroupUser CHECK (
      CASE WHEN OwnerGroup IS NULL THEN 0 ELSE 1 END +
      CASE WHEN OwnerUser  IS NULL THEN 0 ELSE 1 END = 1
    )
);

As you can see, the Ticket table has two columns, OwnerGroup and OwnerUser, both of which are nullable foreign keys. (The respective columns in the other two tables are made primary keys accordingly.) The CK_Ticket_GroupUser check constraint ensures that only one of the two foreign key columns contains a reference (the other being NULL, that's why both have to be nullable).

(The primary key on Ticket.ID is not necessary for this particular implementation, but it definitely wouldn't harm to have one in a table like this.)

try this out

$("div[id^='car']:last").after($('#car2').clone());

An unusual but pretty way of doing it

Without index:

each _ in Array(5)
  = 'a'

Will print: aaaaa

With index:

each _, i in Array(5)
  = i

Will print: 01234

Notes: In the examples above, I have assigned the val parameter of jade's each iteration syntax to _ because it is required, but will always return undefined.

Using balexandre's info:

The one-liner that Andre Miller posted above works except for recent versions of sed when the input file ends with a blank line and no chars. On my Mac my CPU just spins.

Infinite loop if last line is blank and has no chars:

sed '$!N; /^\(.*\)\n\1$/!P; D'

Doesn't hang, but you lose the last line

sed '$d;N; /^\(.*\)\n\1$/!P; D'

The explanation is at the very end of the sed FAQ:

The GNU sed maintainer felt that despite the portability problems
this would cause, changing the N command to print (rather than
delete) the pattern space was more consistent with one's intuitions
about how a command to "append the Next line" ought to behave.
Another fact favoring the change was that "{N;command;}" will
delete the last line if the file has an odd number of lines, but
print the last line if the file has an even number of lines.

To convert scripts which used the former behavior of N (deleting
the pattern space upon reaching the EOF) to scripts compatible with
all versions of sed, change a lone "N;" to "$d;N;".

To create a spreadsheet and format a cell using POI, see the Working with Fonts example, and use:

font.setBoldweight(Font.BOLDWEIGHT_BOLD);

POI works very well. There are some things you can't do (e.g. create VBA macros), but it'll read/write spreadsheets with macros, so you can create a suitable template sheet, read it and manipulate it with POI, and then write it out.

Of the top of my head, can you try to use the 'q' operator for the string literal

something like

insert all
  into domo_queries values (q'[select 
substr(to_char(max_data),1,4) as year,
substr(to_char(max_data),5,6) as month,
max_data
from dss_fin_user.acq_dashboard_src_load_success
where source = 'CHQ PeopleSoft FS']')
select * from dual;

Note that the single quotes of your predicate are not escaped, and the string sits between q'[...]'.

You could replace any view at any time.

int optionId = someExpression ? R.layout.option1 : R.layout.option2;

View C = findViewById(R.id.C);
ViewGroup parent = (ViewGroup) C.getParent();
int index = parent.indexOfChild(C);
parent.removeView(C);
C = getLayoutInflater().inflate(optionId, parent, false);
parent.addView(C, index);

If you don't want to replace already existing View, but choose between option1/option2 at initialization time, then you could do this easier: set android:id for parent layout and then:

ViewGroup parent = (ViewGroup) findViewById(R.id.parent);
View C = getLayoutInflater().inflate(optionId, parent, false);
parent.addView(C, index);

You will have to set "index" to proper value depending on views structure. You could also use a ViewStub: add your C view as ViewStub and then:

ViewStub C = (ViewStub) findViewById(R.id.C);
C.setLayoutResource(optionId);
C.inflate();

That way you won't have to worry about above "index" value if you will want to restructure your XML layout.

You can use the method Substring method that takes a single parameter, which is the index to start from.

In my code below i deal with the case were the length is less than your desired start index and when the length is zero.

string s = "hello world!";
s = s.Substring(Math.Max(0, Math.Min(10, s.Length - 1)));

I used to have this following line in the csproj file:

<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" />

After deleting this file, it works fine.

You can use extension methods to do the same thing with less code.

public enum AccountType
{
    Retailer = 1,
    Customer = 2,
    Manager = 3,
    Employee = 4
}

static class AccountTypeMethods
{
    public static bool IsRetailer(this AccountType ac)
    {
        return ac == AccountType.Retailer;
    }
}

And to use:

if (userProfile.AccountType.isRetailer())
{
    //your code
}

I would recommend to rename the AccountType to Account. It's not a name convention.

The next step would be FisherFaces. Try it and check whether they work for you. Here is a nice comparison.

The problem is that you have a circular import: in app.py

from mod_login import mod_login

in mod_login.py

from app import app

This is not permitted in Python. See Circular import dependency in Python for more info. In short, the solution are

• either gather everything in one big file
• delay one of the import using local import

Using fgetc(fp) only to be able to call strcpy(buffer,c); doesn't seem right.

You could simply build this buffer on your own:

char buffer[MAX_SIZE_OF_MY_BUFFER];

int i = 0;
char ch;
while (i < MAX_SIZE_OF_MY_BUFFER - 1 && (ch = fgetc(fp)) != EOF) {
    buffer[i++] = ch;
}
buffer[i] = '\0';  // terminating character

Note that this relies on the fact that you will read less than MAX_SIZE_OF_MY_BUFFER characters

to make it faster, you can add a break; that way the loop will stop if found is set to true:

boolean found = false;
for(Object1 object1 : list1){
   for(Object2 object2: list2){
       if(object1.getAttributeSame() == object2.getAttributeSame()){
           found = true;
           //also do something  
           break;
       }
    }
    if(!found){
        //do something
    }
    found = false;
}

If you would have maps in stead of lists with as keys the attributeSame, you could check faster for a value in one map if there is a corresponding value in the second map or not.

If you want to add you custom Overlay screen on Layout, you can create a Custom Linear Layout and get control of drawing and key events. You can my tutorial- Overlay on Android Layout- http://prasanta-paul.blogspot.com/2010/08/overlay-on-android-layout.html

It means you did something like this.

Class myObject = GetObjectFromFunction();

And without doing

if(myObject!=null), you go ahead do myObject.Method();

you can covert domain to IP address because every Domain have specific IP address, then you will solve that issue. I hope this will help you.

Using true/false as the value will have the field pre-filled if the model passed to the form has this attribute already filled:

= f.radio_button(:public?, true)
= f.label(:public?, "yes", value: true)
= f.radio_button(:public?, false)
= f.label(:public?, "no", value: false)

var fs = require("fs");

function readFileLineByLine(filename, processline) {
    var stream = fs.createReadStream(filename);
    var s = "";
    stream.on("data", function(data) {
        s += data.toString('utf8');
        var lines = s.split("\n");
        for (var i = 0; i < lines.length - 1; i++)
            processline(lines[i]);
        s = lines[lines.length - 1];
    });

    stream.on("end",function() {
        var lines = s.split("\n");
        for (var i = 0; i < lines.length; i++)
            processline(lines[i]);
    });
}

var linenumber = 0;
readFileLineByLine(filename, function(line) {
    console.log(++linenumber + " -- " + line);
});

I used jQuery Grid Plugin, it was nice.

Demos

You can save the best model using keras.callbacks.ModelCheckpoint()

Example:

model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy'])
model_checkpoint_callback = keras.callbacks.ModelCheckpoint("best_Model.h5",save_best_only=True)
history = model.fit(x_train,y_train,
          epochs=10,
          validation_data=(x_valid,y_valid),
          callbacks=[model_checkpoint_callback])

This will save the best model in your working directory.

Not quite

int main(void)
{
   #if 0
     the apostrophe ' causes a warning
   #endif
   return 0;
}

It shows "t.c:4:19: warning: missing terminating ' character" with gcc 4.2.4

This should work:

 cat "$API" >> "$CONFIG"

You need to use the >> operator to append to a file. Redirecting with > causes the file to be overwritten. (truncated).

You should use destroy() to close a tkinter window.

from Tkinter import *

root = Tk()
Button(root, text="Quit", command=root.destroy).pack()
root.mainloop()

Explanation:

root.quit()

The above line just Bypasses the root.mainloop() i.e root.mainloop() will still be running in background if quit() command is executed.

root.destroy()

While destroy() command vanish out root.mainloop() i.e root.mainloop() stops.

So as you just want to quit the program so you should use root.destroy() as it will it stop the mainloop().

But if you want to run some infinite loop and you don't want to destroy your Tk window and want to execute some code after root.mainloop() line then you should use root.quit(). Ex:

from Tkinter import *
def quit():
    global root
    root.quit()

root = Tk()
while True:
    Button(root, text="Quit", command=quit).pack()
    root.mainloop()
    #do something

You can use:

 mpstat -P ALL 1

It shows how much each core is busy and it updates automatically each second. The output would be something like this (on a quad-core processor):

10:54:41 PM  CPU    %usr   %nice    %sys %iowait    %irq   %soft  %steal  %guest   %idle

This command doesn't answer original question though i.e. it does not show CPU core usage for a specific process.

If you can't rename the original file, you could also use a symlink:

ln -s foo-bar.py foo_bar.py

Then you can just:

from foo_bar import *

Might be a bit overkill, but when I work with ascii and unicode in same files, repeating decode can be a pain, this is what I use:

def make_unicode(input):
    if type(input) != unicode:
        input =  input.decode('utf-8')
    return input

var name = $('#myElement').attr('name');

(In reply to the "has the situation improved?" part of the question):

Unfortunately, not really. Illustrator's support for SVG has always been a little shaky, and, having mucked around in Illustrator's internals, I doubt we'll see much improvement as far as Illustrator is concerned.

If you're looking for DOM-style access to an Illustrator document, you might want to check out Hanpuku (Disclosure #1: I'm the author. Disclosure #2: It's research code, meaning there are bugs aplenty, and future support is unlikely).

With Hanpuku, you could do something like:

1. Select the path of interest in Illustrator
2. Click the "To D3" button

3. In the script editor, type:

   selection.attr('d', 'M 0 0 L 20 134 L 233 24 Z');

4. Click run

5. If the change is as expected, click "To Illustrator" to apply the changes to the document

Granted, this approach doesn't expose the original path string. If you follow the instructions toward the end of the plugin's welcome page, it's possible to edit the Illustrator document with Chrome's developer tools, but there will be lots of ugly engineering exposed everywhere (the SVG DOM that mirrors the Illustrator document is buried inside an iframe deep in the extension—changing the DOM with Chrome's tools and clicking "To Illustrator" should still work, but you will likely encounter lots of problems).

TL;DR: Illustrator uses an internal model that's pretty different from SVG in a lot of ways, meaning that when you iterate between the two, currently, your only choice is to use the subset of features that both support in the same way.

Cross-browser URL parsing, works around the relative path problem for IE 6, 7, 8 and 9:

function ParsedUrl(url) {
    var parser = document.createElement("a");
    parser.href = url;

    // IE 8 and 9 dont load the attributes "protocol" and "host" in case the source URL
    // is just a pathname, that is, "/example" and not "http://domain.com/example".
    parser.href = parser.href;

    // IE 7 and 6 wont load "protocol" and "host" even with the above workaround,
    // so we take the protocol/host from window.location and place them manually
    if (parser.host === "") {
        var newProtocolAndHost = window.location.protocol + "//" + window.location.host;
        if (url.charAt(1) === "/") {
            parser.href = newProtocolAndHost + url;
        } else {
            // the regex gets everything up to the last "/"
            // /path/takesEverythingUpToAndIncludingTheLastForwardSlash/thisIsIgnored
            // "/" is inserted before because IE takes it of from pathname
            var currentFolder = ("/"+parser.pathname).match(/.*\//)[0];
            parser.href = newProtocolAndHost + currentFolder + url;
        }
    }

    // copies all the properties to this object
    var properties = ['host', 'hostname', 'hash', 'href', 'port', 'protocol', 'search'];
    for (var i = 0, n = properties.length; i < n; i++) {
      this[properties[i]] = parser[properties[i]];
    }

    // pathname is special because IE takes the "/" of the starting of pathname
    this.pathname = (parser.pathname.charAt(0) !== "/" ? "/" : "") + parser.pathname;
}

Usage (demo JSFiddle here):

var myUrl = new ParsedUrl("http://www.example.com:8080/path?query=123#fragment");

Result:

{
    hash: "#fragment"
    host: "www.example.com:8080"
    hostname: "www.example.com"
    href: "http://www.example.com:8080/path?query=123#fragment"
    pathname: "/path"
    port: "8080"
    protocol: "http:"
    search: "?query=123"
}

printf allows various formatting options.

Example:

printf("leading zeros %05d", 123);

Well I know this might be a big change or even not suitable for your project, but did you consider not performing the push until you already have the data? That way you only need to draw the view once and the user experience will also be better - the push will move in already loaded.

The way you do this is in the UITableView didSelectRowAtIndexPath you asynchronously ask for the data. Once you receive the response, you manually perform the segue and pass the data to your viewController in prepareForSegue. Meanwhile you may want to show some activity indicator, for simple loading indicator check https://github.com/jdg/MBProgressHUD

SELECT field1, field2, 'Test' AS field3 FROM Test; // replace with simple quote '

preg_replace('/^[^:\/?]+:\/\//','',$url); 

some results:

input: http://php.net/preg_replace output: php.net/preg_replace  input: https://www.php.net/preg_replace output: www.php.net/preg_replace  input: ftp://www.php.net/preg_replace output: www.php.net/preg_replace  input: https://php.net/preg_replace?url=http://whatever.com output: php.net/preg_replace?url=http://whatever.com  input: php.net/preg_replace?url=http://whatever.com output: php.net/preg_replace?url=http://whatever.com  input: php.net?site=http://whatever.com output: php.net?site=http://whatever.com 

Filter: - A filter as the name suggests is a Java class executed by the servlet container for each incoming HTTP request and for each http response. This way, is possible to manage HTTP incoming requests before them reach the resource, such as a JSP page, a servlet or a simple static page; in the same way is possible to manage HTTP outbound response after resource execution.

Interceptor: - Spring Interceptors are similar to Servlet Filters but they acts in Spring Context so are many powerful to manage HTTP Request and Response but they can implement more sophisticated behavior because can access to all Spring context.

One-liner in java 8 syntax:

pdfTestDir.listFiles((dir, name) -> name.toLowerCase().endsWith(".txt"));

I keep hearing people say they're forking code in git. Git "fork" sounds suspiciously like git "clone" plus some (meaningless) psychological willingness to forgo future merges. There is no fork command in git, right?

"Forking" is a concept, not a command specifically supported by any version control system.

The simplest kind of forking is synonymous with branching. Every time you create a branch, regardless of your VCS, you've "forked". These forks are usually pretty easy to merge back together.

The kind of fork you're talking about, where a separate party takes a complete copy of the code and walks away, necessarily happens outside the VCS in a centralized system like Subversion. A distributed VCS like Git has much better support for forking the entire codebase and effectively starting a new project.

Git (not GitHub) natively supports "forking" an entire repo (ie, cloning it) in a couple of ways:

• when you clone, a remote called origin is created for you
• by default all the branches in the clone will track their origin equivalents
• fetching and merging changes from the original project you forked from is trivially easy

Git makes contributing changes back to the source of the fork as simple as asking someone from the original project to pull from you, or requesting write access to push changes back yourself. This is the part that GitHub makes easier, and standardizes.

Any angst over Github extending git in this direction? Or any rumors of git absorbing the functionality?

There is no angst because your assumption is wrong. GitHub "extends" the forking functionality of Git with a nice GUI and a standardized way of issuing pull requests, but it doesn't add the functionality to Git. The concept of full-repo-forking is baked right into distributed version control at a fundamental level. You could abandon GitHub at any point and still continue to push/pull projects you've "forked".

Here is a more complete example using a fieldset for accessibility reasons and specifying the first button as the default. Without a fieldset, what the radio buttons are for as a whole can not be programmatically determined.

Model

public class MyModel
{
    public bool IsMarried { get; set; }
}

View

<fieldset>
    <legend>Married</legend>

    @Html.RadioButtonFor(e => e.IsMarried, true, new { id = "married-true" })
    @Html.Label("married-true", "Yes")

    @Html.RadioButtonFor(e => e.IsMarried, false, new { id = "married-false" })
    @Html.Label("married-false", "No")
</fieldset>

You can add a @checked argument to the anonymous object to set the radio button as the default:

new { id = "married-true", @checked = 'checked' }

Note that you can bind to a string by replacing true and false with the string values.

An easy short hand way would be to use +x It keeps the sign intact as well as the decimal numbers. The other alternative is to use parseFloat(x). Difference between parseFloat(x) and +x is for a blank string +x returns 0 where as parseFloat(x) returns NaN.

To view the stdout, you can start the docker container with -i. This of course does not enable you to leave the started process and explore the container.

docker start -i containerid

Alternatively you can view the filesystem of the container at

/var/lib/docker/containers/containerid/root/

However neither of these are ideal. If you want to view logs or any persistent storage, the correct way to do so would be attaching a volume with the -v switch when you use docker run. This would mean you can inspect log files either on the host or attach them to another container and inspect them there.

Git 1.8.2 features a new option, --remote, that will enable exactly this behavior. Running

git submodule update --remote --merge

will fetch the latest changes from upstream in each submodule, merge them in, and check out the latest revision of the submodule. As the documentation puts it:

--remote

This option is only valid for the update command. Instead of using the superproject’s recorded SHA-1 to update the submodule, use the status of the submodule’s remote-tracking branch.

This is equivalent to running git pull in each submodule, which is generally exactly what you want.

Very easy solution (2 min to config) is to use local-ssl-proxy package from npm

The usage is straight pretty forward:
1. Install the package: npm install -g local-ssl-proxy
2. While running your local-server mask it with the local-ssl-proxy --source 9001 --target 9000

P.S: Replace --target 9000 with the -- "number of your port" and --source 9001 with --source "number of your port +1"

You can try to implement direct link node -> fastcgi -> php. In the previous answer, nginx serves php requests using http->fastcgi serialisation->unix socket->php and node requests as http->nginx reverse proxy->node http server.

It seems that node-fastcgi paser is useable at the moment, but only as a node fastcgi backend. You need to adopt it to use as a fastcgi client to php fastcgi server.

.class {
    background-color:none;
}

This is not a valid property. W3C validator will display following error:

Value Error : background-color none is not a background-color value : none

transparent may have been selected as better term instead of 0 or none values during the development of specification of CSS.

You can concatenate the arrays with +, building a new array

let c = a + b
print(c) // [1.0, 2.0, 3.0, 4.0, 5.0, 6.0]

or append one array to the other with += (or append):

a += b

// Or:
a.append(contentsOf: b)  // Swift 3
a.appendContentsOf(b)    // Swift 2
a.extend(b)              // Swift 1.2

print(a) // [1.0, 2.0, 3.0, 4.0, 5.0, 6.0]

I used the RowHeight property of a range (which means cells as well). If it's zero then it's hidden. So just loop through all rows as you would normally but in the if condition check for that property as in If myRange.RowHeight > 0 then DoStuff where DoStuff is something you want to do with the visible cells.

Use in simple way with php prebuilt function:

function checkmydate($date) {
  $tempDate = explode('-', $date);
  // checkdate(month, day, year)
  return checkdate($tempDate[1], $tempDate[2], $tempDate[0]);
}

Test

   checkmydate('2015-12-01'); //true
   checkmydate('2015-14-04'); //false

If your connection is in background thread then you should update UI in main thread like this

self.tblMainTable.performSelectorOnMainThread(Selector("reloadData"), withObject: nil, waitUntilDone: true)

As I have mentioned here

Swift 4:

self.tblMainTable.performSelector(onMainThread: #selector(UICollectionView.reloadData), with: nil, waitUntilDone: true)

To delete content without a folder you can use the following:

Remove-Item "foldertodelete\*" -Force -Recurse

This page is a neat summary, but is not entirely accurate:

Raw strings are not a different kind of string. They are a different way of describing a string in your source code. Once the string is created, it is what it is.

First, I see you're using an explicit $.parseJSON(). If that's because you're manually serializing JSON on the server-side, don't. ASP.NET will automatically JSON-serialize your method's return value and jQuery will automatically deserialize it for you too.

To iterate through the first item in the array you've got there, use code like this:

var firstItem = response.d[0];

for(key in firstItem) {
  console.log(key + ':' + firstItem[key]);
}

If there's more than one item (it's hard to tell from that screenshot), then you can loop over response.d and then use this code inside that outer loop.

You can use this library:
https://github.com/kmfish/MultiTypeListViewAdapter (written by me)

• Better reuse the code of one cell
• Better expansion
• Better decoupling

Setup adapter:

adapter = new BaseRecyclerAdapter();
adapter.registerDataAndItem(TextModel.class, LineListItem1.class);
adapter.registerDataAndItem(ImageModel.class, LineListItem2.class);
adapter.registerDataAndItem(AbsModel.class, AbsLineItem.class);

For each line item:

public class LineListItem1 extends BaseListItem<TextModel, LineListItem1.OnItem1ClickListener> {

    TextView tvName;
    TextView tvDesc;


    @Override
    public int onGetLayoutRes() {
        return R.layout.list_item1;
    }

    @Override
    public void bindViews(View convertView) {
        Log.d("item1", "bindViews:" + convertView);
        tvName = (TextView) convertView.findViewById(R.id.text_name);
        tvDesc = (TextView) convertView.findViewById(R.id.text_desc);

        tvName.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (null != attachInfo) {
                    attachInfo.onNameClick(getData());
                }
            }
        });
        tvDesc.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (null != attachInfo) {
                    attachInfo.onDescClick(getData());
                }
            }
        });

    }

    @Override
    public void updateView(TextModel model, int pos) {
        if (null != model) {
            Log.d("item1", "updateView model:" + model + "pos:" + pos);
            tvName.setText(model.getName());
            tvDesc.setText(model.getDesc());
        }
    }

    public interface OnItem1ClickListener {
        void onNameClick(TextModel model);
        void onDescClick(TextModel model);
    }
}

If your are using HTML5 then try following code snippet

<img id="uploadPreview" style="width: 100px; height: 100px;" />
<input id="uploadImage" type="file" name="myPhoto" onchange="PreviewImage();" />
<script type="text/javascript">

    function PreviewImage() {
        var oFReader = new FileReader();

Teylyn's answer worked great for me, but I had to modify it a bit to get proper results. I want to provide an extended explanation for whoever would need it.

My setup was as follows:

• Sheet1: full data of 2014
• Sheet2: updated rows for 2015 in A1:D50, sorted by first column
• Sheet3: merged rows
• My data does not have a header row

I put the following formula in cell A1 of Sheet3:

=iferror(vlookup(Sheet1!A$1;Sheet2!$A$1:$D$50;column(A1);false);Sheet1!A1)

Read this as follows: Take the value of the first column in Sheet1 (old data). Look up in Sheet2 (updated rows). If present, output the value from the indicated column in Sheet2. On error, output the value for the current column of Sheet1.

Notes:

• In my version of the formula, ";" is used as parameter separator instead of ",". That is because I am located in Europe and we use the "," as decimal separator. Change ";" back to "," if you live in a country where "." is the decimal separator.

• A$1: means always take column 1 when copying the formula to a cell in a different column. $A$1 means: always take the exact cell A1, even when copying the formula to a different row or column.

After pasting the formula in A1, I extended the range to columns B, C, etc., until the full width of my table was reached. Because of the $-signs used, this gives the following formula's in cells B1, C1, etc.:

=IFERROR(VLOOKUP('Sheet1'!$A1;'Sheet2'!$A$1:$D$50;COLUMN(B1);FALSE);'Sheet1'!B1)
=IFERROR(VLOOKUP('Sheet1'!$A1;'Sheet2'!$A$1:$D$50;COLUMN(C1);FALSE);'Sheet1'!C1)

and so forth. Note that the lookup is still done in the first column. This is because VLOOKUP needs the lookup data to be sorted on the column where the lookup is done. The output column is however the column where the formula is pasted.

Next, select a rectangle in Sheet 3 starting at A1 and having the size of the data in Sheet1 (same number of rows and columns). Press Ctrl-D to copy the formulas of the first row to all selected cells.

Cells A2, A3, etc. will get these formulas:

=IFERROR(VLOOKUP('Sheet1'!$A2;'Sheet2'!$A$1:$D$50;COLUMN(A2);FALSE);'Sheet1'!A2)
=IFERROR(VLOOKUP('Sheet1'!$A3;'Sheet2'!$A$1:$D$50;COLUMN(A3);FALSE);'Sheet1'!A3)

Because of the use of $-signs, the lookup area is constant, but input data is used from the current row.
