I was having this problem after I installed the dotnet-ef tool using Ansible with sudo escalated previllage on Ubuntu. I had to add become: no for the Playbook task, then the dotnet-ef tool became available to the current user.

become: no
An alternative to Environment.NewLine is to use :
Regex.Unescape("\n\tHello World\n")
from System.Text.RegularExpressions
This allows you to escape Text without Concatenating strings as you can in C#, C, java
How about:
df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x
To do all these operations in one-liner:
setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))
#[1] name age gender
#<0 rows> (or 0-length row.names)
Or
data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))
Your code
enum Test
{
A, B
}
int a = 1;
Solution
Test castEnum = static_cast<Test>(a);

// Daylight Saving time
if (timeZone.useDaylightTime()) {
// DST is used
// I'm saving this is preferences for later use
// save the offset value to use it later
float dstOffset = timeZone.getDSTSavings() / ONE_HOUR_MILLIS;

I haven't been able to get it to work without specifying a width but the following css worked
.wrapper {

padding: 10px;
display: inline-block;
height: 20px;
width: auto;
}
.contents {
background: #c3c;
overflow: hidden;
white-space: nowrap;
display: inline-block;
visibility: hidden;
width: 1px;
-webkit-transition: width 1s ease-in-out, visibility 1s linear;
-moz-transition: width 1s ease-in-out, visibility 1s linear;
-o-transition: width 1s ease-in-out, visibility 1s linear;
transition: width 1s ease-in-out, visibility 1s linear;
}
.wrapper:hover .contents {
width: 200px;
visibility: visible;
}
I'm not sure you will be able to get it working without setting a width on it.
Java 8 user can do that: list.removeIf(...)
List<String> list = new ArrayList<>(Arrays.asList("a", "b", "c"));
list.removeIf(e -> (someCondition));
It will remove elements in the list, for which someCondition is satisfied

Python is not Java, nor C/C++ -- you need to stop thinking that way to really utilize the power of Python.
Python does not have pass-by-value, nor pass-by-reference, but instead uses pass-by-name (or pass-by-object) -- in other words, nearly everything is bound to a name that you can then use (the two obvious exceptions being tuple- and list-indexing).
When you do spam = "green"
, you have bound the name spam
to the string object "green"
; if you then do eggs = spam
you have not copied anything, you have not made reference pointers; you have simply bound another name, eggs
, to the same object ("green"
in this case). If you then bind spam
to something else (spam = 3.14159
) eggs
will still be bound to "green"
.
When a for-loop executes, it takes the name you give it, and binds it in turn to each object in the iterable while running the loop; when you call a function, it takes the names in the function header and binds them to the arguments passed; reassigning a name is actually rebinding a name (it can take a while to absorb this -- it did for me, anyway).
With for-loops utilizing lists, there are two basic ways to assign back to the list:
for i, item in enumerate(some_list):
some_list[i] = process(item)
or
new_list = []
for item in some_list:
new_list.append(process(item))
some_list[:] = new_list
Notice the [:]
on that last some_list
-- it is causing a mutation of some_list
's elements (setting the entire thing to new_list
's elements) instead of rebinding the name some_list
to new_list
. Is this important? It depends! If you have other names besides some_list
bound to the same list object, and you want them to see the updates, then you need to use the slicing method; if you don't, or if you do not want them to see the updates, then rebind -- some_list = new_list
.
Your code alerts the current value of the dropdown for me, showing that it has properly pushed into the array.
Are you wanting to keep old values and append? You're recreating the array each time, meaning that the old value gets clobbered.
Here's some updated code:
var myarray = [];
$("#test").click(function() {
myarray.push($("#drop").val());
alert(myarray);
});
Correct answers. OK, now I like git. :-) Here's a simpler recipe.
git log HEAD@{2}
git reset --hard HEAD@{2}
Where "2" is the number of back to where you committed your changes. In my case, interrupted by colleague and boss to help debug some build issue; so, did a reset --hard twice; so, HEAD and HEAD@{1} were over-writes. Whew, would have lost an our of hard work.
Update: In EF 6.2 there is a like operator
Where(obj => DbFunctions.Like(obj.Column , "%expression%")
If you are exporting another class in that module, make sure that it is not in between @Component
and your ClassComponent
. For example:
@Component({ ... })
export class ExampleClass{}
export class ComponentClass{} --> this will give this error.
FIX:
export class ExampleClass{}
@Component ({ ... })
export class ComponentClass{}
I had the same problem, put the ! outside the brackets;
while ! [ -f /tmp/list.txt ];

Also, if you add an echo inside the loop it will tell you if you are getting into the loop or not.
Add this overriding method to your WebViewClient implementation. You'll need to compile it with Android SDK 2.2 (API level 8) or later. The method appears in the public SDK as of 2.2 (API level 8) but we've tested it on devices running 2.1, 1.6 and 1.5 and it works on those devices too (so obviously the behaviour has been there all along).
@Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
handler.proceed(); // Ignore SSL certificate errors
}
this will help you.
I'm late to the party, but here's a small and easy solution I came up with to return an amount of words.
It's not directly related to your requirement of characters, but it serves the same outcome that I believe you were after.
function truncateWords(sentence, amount, tail) {
const words = sentence.split(' ');
if (amount >= words.length) {
return sentence;
}
const truncated = words.slice(0, amount);
return `${truncated.join(' ')}${tail}`;
}
const sentence = 'Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo.';
console.log(truncateWords(sentence, 10, '...'));
See the working example here: https://jsfiddle.net/bx7rojgL/

If you can invert your logic you can use the Array.Clear()

Array.Clear(seiveContainer, 0, upperLimit);

If we need to show different type of view in list-view then its good to use getViewTypeCount() and getItemViewType() in adapter instead of toggling a view VIEW.GONE and VIEW.VISIBLE can be very expensive task inside getView() which will affect the list scroll.

I give all my popovers anchors the class activate_popover
. I activate them all at once onload
$('body').popover({selector: '.activate-popover', html : true, container: 'body'})
to get the click away functionality working I use (in coffee script):
$(document).on('click', (e) ->
clickedOnActivate = ($(e.target).parents().hasClass("activate-popover") || $(e.target).hasClass("activate-popover"))
clickedAway = !($(e.target).parents().hasClass("popover") || $(e.target).hasClass("popover"))
if clickedAway && !clickedOnActivate
$(".popover.in").prev().popover('hide')
if clickedOnActivate
$(".popover.in").prev().each () ->
if !$(this).is($(e.target).closest('.activate-popover'))
$(this).popover('hide')
)
Which works perfectly fine with bootstrap 2.3.1

Recently I am working with the 1.8.0_25 JDK version on Windows 8.1 and I had the same problem with this. But as PankaJ Jakhar said
The real solution for me was pretty simple:
The path I introduced for this variable was:
C:\Program Files\Java\jdk1.8.0_25\
And it works for me!
$('tr').click(function(){
alert( $('tr').index(this) );
});
For first tr
, it alerts 0. If you want to alert 1, you can add 1 to index.

Your answer is in wikipedia: modulo operation
It says, that in Java the sign on modulo operation is the same as that of dividend. and since we're talking about the rest of the division operation is just fine, that it returns -13 in your case, since -13/64 = 0. -13-0 = -13.
EDIT: Sorry, misunderstood your question...You're right, java should give -13. Can you provide more surrounding code?
What you are looking for can be found here. It may exist a more elegant way to accomplish that, but one possible approach is
final Duration timeout = Duration.ofSeconds(30);
ExecutorService executor = Executors.newSingleThreadExecutor();
final Future<String> handler = executor.submit(new Callable() {
@Override
public String call() throws Exception {
return requestDataFromModem();
}
});
try {
handler.get(timeout.toMillis(), TimeUnit.MILLISECONDS);
} catch (TimeoutException e) {
handler.cancel(true);
}
executor.shutdownNow();
final Duration timeout = Duration.ofSeconds(30);
ScheduledExecutorService executor = Executors.newScheduledThreadPool(1);
final Future<String> handler = executor.submit(new Callable() {
@Override
public String call() throws Exception {
return requestDataFromModem();
}
});
executor.schedule(new Runnable() {
@Override
public void run(){
handler.cancel(true);
}
}, timeout.toMillis(), TimeUnit.MILLISECONDS);
executor.shutdownNow();

The Original Question
Why is one loop so much slower than two loops?
Conclusion:
Case 1 is a classic interpolation problem that happens to be an inefficient one. I also think that this was one of the leading reasons why many machine architectures and developers ended up building and designing multi-core systems with the ability to do multi-threaded applications as well as parallel programming.
Looking at it from this kind of an approach without involving how the hardware, OS, and compiler(s) work together to do heap allocations that involve working with RAM, cache, page files, etc.; the mathematics that is at the foundation of these algorithms shows us which of these two is the better solution.
We can use an analogy of a Boss
being a Summation
that will represent a For Loop
that has to travel between workers A
& B
.
We can easily see that Case 2 is at least half as fast if not a little more than Case 1 due to the difference in the distance that is needed to travel and the time taken between the workers. This math lines up almost virtually and perfectly with both the benchmark times as well as the number of differences in assembly instructions.
I will now begin to explain how all of this works below.
Assessing The Problem
The OP's code:
const int n=100000;
for(int j=0;j<n;j++){
a1[j] += b1[j];
c1[j] += d1[j];
}
And
for(int j=0;j<n;j++){
a1[j] += b1[j];
}
for(int j=0;j<n;j++){
c1[j] += d1[j];
}
The Consideration
Considering the OP's original question about the two variants of the for
loops and his amended question towards the behavior of caches along with many of the other excellent answers and useful comments; I'd like to try and do something different here by taking a different approach about this situation and problem.
The Approach
Considering the two loops and all of the discussion about cache and page filing I'd like to take another approach as to looking at this from a different perspective. One that doesn't involve the cache and page files nor the executions to allocate memory, in fact, this approach doesn't even concern the actual hardware or the software at all.
The Perspective
After looking at the code for a while it became quite apparent what the problem is and what is generating it. Let's break this down into an algorithmic problem and look at it from the perspective of using mathematical notations then apply an analogy to the math problems as well as to the algorithms.
What We Do Know
We know is that this loop will run 100,000 times. We also know that a1
, b1
, c1
& d1
are pointers on a 64-bit architecture. Within C++ on a 32-bit machine, all pointers are 4 bytes and on a 64-bit machine, they are 8 bytes in size since pointers are of a fixed length.
We know that we have 32 bytes in which to allocate for in both cases. The only difference is we are allocating 32 bytes or two sets of 2-8 bytes on each iteration wherein the second case we are allocating 16 bytes for each iteration for both of the independent loops.
Both loops still equal 32 bytes in total allocations. With this information let's now go ahead and show the general math, algorithms, and analogy of these concepts.
We do know the number of times that the same set or group of operations that will have to be performed in both cases. We do know the amount of memory that needs to be allocated in both cases. We can assess that the overall workload of the allocations between both cases will be approximately the same.
What We Don't Know
We do not know how long it will take for each case unless if we set a counter and run a benchmark test. However, the benchmarks were already included from the original question and from some of the answers and comments as well; and we can see a significant difference between the two and this is the whole reasoning for this proposal to this problem.
Let's Investigate
It is already apparent that many have already done this by looking at the heap allocations, benchmark tests, looking at RAM, cache, and page files. Looking at specific data points and specific iteration indices were also included and the various conversations about this specific problem have many people starting to question other related things about it. How do we begin to look at this problem by using mathematical algorithms and applying an analogy to it? We start off by making a couple of assertions! Then we build out our algorithm from there.
Our Assertions:
F1()
, F2()
, f(a)
, f(b)
, f(c)
and f(d)
.The Algorithms:
1st Case: - Only one summation but two independent function calls.
Sum n=1 : [1,100000] = F1(), F2();
F1() = { f(a) = f(a) + f(b); }
F2() = { f(c) = f(c) + f(d); }
2nd Case: - Two summations but each has its own function call.
Sum1 n=1 : [1,100000] = F1();
F1() = { f(a) = f(a) + f(b); }
Sum2 n=1 : [1,100000] = F1();
F1() = { f(c) = f(c) + f(d); }
If you noticed F2()
only exists in Sum
from Case1
where F1()
is contained in Sum
from Case1
and in both Sum1
and Sum2
from Case2
. This will be evident later on when we begin to conclude that there is an optimization that is happening within the second algorithm.
The iterations through the first case Sum
calls f(a)
that will add to its self f(b)
then it calls f(c)
that will do the same but add f(d)
to itself for each 100000
iterations. In the second case, we have Sum1
and Sum2
that both act the same as if they were the same function being called twice in a row.
In this case we can treat Sum1
and Sum2
as just plain old Sum
where Sum
in this case looks like this: Sum n=1 : [1,100000] { f(a) = f(a) + f(b); }
and now this looks like an optimization where we can just consider it to be the same function.
Summary with Analogy
With what we have seen in the second case it almost appears as if there is optimization since both for loops have the same exact signature, but this isn't the real issue. The issue isn't the work that is being done by f(a)
, f(b)
, f(c)
, and f(d)
. In both cases and the comparison between the two, it is the difference in the distance that the Summation has to travel in each case that gives you the difference in execution time.
Think of the for
loops as being the summations that does the iterations as being a Boss
that is giving orders to two people A
& B
and that their jobs are to meat C
& D
respectively and to pick up some package from them and return it. In this analogy, the for loops or summation iterations and condition checks themselves don't actually represent the Boss
. What actually represents the Boss
is not from the actual mathematical algorithms directly but from the actual concept of Scope
and Code Block
within a routine or subroutine, method, function, translation unit, etc. The first algorithm has one scope where the second algorithm has two consecutive scopes.
Within the first case on each call slip, the Boss
goes to A
and gives the order and A
goes off to fetch B's
package then the Boss
goes to C
and gives the orders to do the same and receive the package from D
on each iteration.
Within the second case, the Boss
works directly with A
to go and fetch B's
package until all packages are received. Then the Boss
works with C
to do the same for getting all of D's
packages.
Since we are working with an 8-byte pointer and dealing with heap allocation let's consider the following problem. Let's say that the Boss
is 100 feet from A
and that A
is 500 feet from C
. We don't need to worry about how far the Boss
is initially from C
because of the order of executions. In both cases, the Boss
initially travels from A
first then to B
. This analogy isn't to say that this distance is exact; it is just a useful test case scenario to show the workings of the algorithms.
In many cases when doing heap allocations and working with the cache and page files, these distances between address locations may not vary that much or they can vary significantly depending on the nature of the data types and the array sizes.
The Test Cases:
First Case: On first iteration the Boss
has to initially go 100 feet to give the order slip to A
and A
goes off and does his thing, but then the Boss
has to travel 500 feet to C
to give him his order slip. Then on the next iteration and every other iteration after the Boss
has to go back and forth 500 feet between the two.
Second Case: The Boss
has to travel 100 feet on the first iteration to A
, but after that, he is already there and just waits for A
to get back until all slips are filled. Then the Boss
has to travel 500 feet on the first iteration to C
because C
is 500 feet from A
. Since this Boss( Summation, For Loop )
is being called right after working with A
he then just waits there as he did with A
until all of C's
order slips are done.
The Difference In Distances Traveled
const n = 100000
distTraveledOfFirst = (100 + 500) + ((n-1)*(500 + 500);
// Simplify
distTraveledOfFirst = 600 + (99999*100);
distTraveledOfFirst = 600 + 9999900;
distTraveledOfFirst = 10000500;
// Distance Traveled On First Algorithm = 10,000,500ft
distTraveledOfSecond = 100 + 500 = 600;
// Distance Traveled On Second Algorithm = 600ft;
The Comparison of Arbitrary Values
We can easily see that 600 is far less than 10 million. Now, this isn't exact, because we don't know the actual difference in distance between which address of RAM or from which cache or page file each call on each iteration is going to be due to many other unseen variables. This is just an assessment of the situation to be aware of and looking at it from the worst-case scenario.
From these numbers it would almost appear as if algorithm one should be 99%
slower than algorithm two; however, this is only the Boss's
part or responsibility of the algorithms and it doesn't account for the actual workers A
, B
, C
, & D
and what they have to do on each and every iteration of the Loop. So the boss's job only accounts for about 15 - 40% of the total work being done. The bulk of the work that is done through the workers has a slightly bigger impact towards keeping the ratio of the speed rate differences to about 50-70%
The Observation: - The differences between the two algorithms
In this situation, it is the structure of the process of the work being done. It goes to show that Case 2 is more efficient from both the partial optimization of having a similar function declaration and definition where it is only the variables that differ by name and the distance traveled.
We also see that the total distance traveled in Case 1 is much farther than it is in Case 2 and we can consider this distance traveled our Time Factor between the two algorithms. Case 1 has considerable more work to do than Case 2 does.
This is observable from the evidence of the assembly instructions that were shown in both cases. Along with what was already stated about these cases, this doesn't account for the fact that in Case 1 the boss will have to wait for both A
& C
to get back before he can go back to A
again for each iteration. It also doesn't account for the fact that if A
or B
is taking an extremely long time then both the Boss
and the other worker(s) are idle waiting to be executed.
In Case 2 the only one being idle is the Boss
until the worker gets back. So even this has an impact on the algorithm.
The OP's Amended Question(s)
EDIT: The question turned out to be of no relevance, as the behavior severely depends on the sizes of the arrays (n) and the CPU cache. So if there is further interest, I rephrase the question:
Could you provide some solid insight into the details that lead to the different cache behaviors as illustrated by the five regions on the following graph?
It might also be interesting to point out the differences between CPU/cache architectures, by providing a similar graph for these CPUs.
Regarding These Questions
As I have demonstrated without a doubt, there is an underlying issue even before the Hardware and Software becomes involved.
Now as for the management of memory and caching along with page files, etc. which all work together in an integrated set of systems between the following:
We can already see that there is a bottleneck that is happening within the first algorithm before we even apply it to any machine with any arbitrary architecture, OS, and programmable language compared to the second algorithm. There already existed a problem before involving the intrinsics of a modern computer.
The Ending Results
However; it is not to say that these new questions are not of importance because they themselves are and they do play a role after all. They do impact the procedures and the overall performance and that is evident with the various graphs and assessments from many who have given their answer(s) and or comment(s).
If you paid attention to the analogy of the Boss
and the two workers A
& B
who had to go and retrieve packages from C
& D
respectively and considering the mathematical notations of the two algorithms in question; you can see without the involvement of the computer hardware and software Case 2
is approximately 60%
faster than Case 1
.
When you look at the graphs and charts after these algorithms have been applied to some source code, compiled, optimized, and executed through the OS to perform their operations on a given piece of hardware, you can even see a little more degradation between the differences in these algorithms.
If the Data
set is fairly small it may not seem all that bad of a difference at first. However, since Case 1
is about 60 - 70%
slower than Case 2
we can look at the growth of this function in terms of the differences in time executions:
DeltaTimeDifference approximately = Loop1(time) - Loop2(time)
//where
Loop1(time) = Loop2(time) + (Loop2(time)*[0.6,0.7]) // approximately
// So when we substitute this back into the difference equation we end up with
DeltaTimeDifference approximately = (Loop2(time) + (Loop2(time)*[0.6,0.7])) - Loop2(time)
// And finally we can simplify this to
DeltaTimeDifference approximately = [0.6,0.7]*Loop2(time)
This approximation is the average difference between these two loops both algorithmically and machine operations involving software optimizations and machine instructions.
When the data set grows linearly, so does the difference in time between the two. Algorithm 1 has more fetches than algorithm 2 which is evident when the Boss
has to travel back and forth the maximum distance between A
& C
for every iteration after the first iteration while algorithm 2 the Boss
has to travel to A
once and then after being done with A
he has to travel a maximum distance only one time when going from A
to C
.
Trying to have the Boss
focusing on doing two similar things at once and juggling them back and forth instead of focusing on similar consecutive tasks is going to make him quite angry by the end of the day since he had to travel and work twice as much. Therefore do not lose the scope of the situation by letting your boss getting into an interpolated bottleneck because the boss's spouse and children wouldn't appreciate it.
Amendment: Software Engineering Design Principles
-- The difference between local Stack and heap allocated computations within iterative for loops and the difference between their usages, their efficiencies, and effectiveness --
The mathematical algorithm that I proposed above mainly applies to loops that perform operations on data that is allocated on the heap.
So when you are working with data that needs to be on the heap and you are traversing through them in loops, it is more efficient to keep each data set and its corresponding algorithms within its own single loop. You will get better optimizations compared to trying to factor out consecutive loops by putting multiple operations of different data sets that are on the heap into a single loop.
It is okay to do this with data that is on the stack since they are frequently cached, but not for data that has to have its memory address queried every iteration.
This is where software engineering and software architecture design comes into play. It is the ability to know how to organize your data, knowing when to cache your data, knowing when to allocate your data on the heap, knowing how to design and implement your algorithms, and knowing when and where to call them.
You might have the same algorithm that pertains to the same data set, but you might want one implementation design for its stack variant and another for its heap-allocated variant just because of the above issue that is seen from its O(n)
complexity of the algorithm when working with the heap.
From what I've noticed over the years, many people do not take this fact into consideration. They will tend to design one algorithm that works on a particular data set and they will use it regardless of the data set being locally cached on the stack or if it was allocated on the heap.
If you want true optimization, yes it might seem like code duplication, but to generalize it would be more efficient to have two variants of the same algorithm. One for stack operations, and the other for heap operations that are performed in iterative loops!
Here's a pseudo example: Two simple structs, one algorithm.
struct A {
int data;
A() : data{0}{}
A(int a) : data{a}{}
};
struct B {
int data;
B() : data{0}{}
A(int b) : data{b}{}
}
template<typename T>
void Foo( T& t ) {
// Do something with t
}
// Some looping operation: first stack then heap.
// Stack data:
A dataSetA[10] = {};
B dataSetB[10] = {};
// For stack operations this is okay and efficient
for (int i = 0; i < 10; i++ ) {
Foo(dataSetA[i]);
Foo(dataSetB[i]);
}
// If the above two were on the heap then performing
// the same algorithm to both within the same loop
// will create that bottleneck
A* dataSetA = new [] A();
B* dataSetB = new [] B();
for ( int i = 0; i < 10; i++ ) {
Foo(dataSetA[i]); // dataSetA is on the heap here
Foo(dataSetB[i]); // dataSetB is on the heap here
} // this will be inefficient.
// To improve the efficiency above, put them into separate loops...
for (int i = 0; i < 10; i++ ) {
Foo(dataSetA[i]);
}
for (int i = 0; i < 10; i++ ) {
Foo(dataSetB[i]);
}
// This will be much more efficient than above.
// The code isn't perfect syntax, it's only psuedo code
// to illustrate a point.
This is what I was referring to by having separate implementations for stack variants versus heap variants. The algorithms themselves don't matter too much, it's the looping structures that you will use them in that do.

For me it worked like that in Kotlin:
my string.xml
<string name="price" formatted="false">Price:U$ %.2f%n</string>
my class.kt
var formatPrice: CharSequence? = null
var unitPrice = 9990
formatPrice = String.format(context.getString(R.string.price), unitPrice/100.0)
Log.d("Double_CharSequence", "$formatPrice")
D/Double_CharSequence: Price :U$ 99,90
For an even better result, we can do so
<string name="price_to_string">Price:U$ %1$s</string>
var formatPrice: CharSequence? = null
var unitPrice = 199990
val numberFormat = (unitPrice/100.0).toString()
formatPrice = String.format(context.getString(R.string.price_to_string), formatValue(numberFormat))
fun formatValue(value: String) :String{
val mDecimalFormat = DecimalFormat("###,###,##0.00")
val s1 = value.toDouble()
return mDecimalFormat.format(s1)
}
Log.d("Double_CharSequence", "$formatPrice")
D/Double_CharSequence: Price :U$ 1.999,90

What's the first part of your Subversion repository URL?
I can't guarantee the first four since it's possible to reconfigure everything to use different ports, of if you go through a proxy of some sort.
If you're using a VPN, you may have to configure your VPN client to reroute these to their correct ports. A lot of places don't configure their correctly VPNs to do this type of proxying. It's either because they have some sort of anal-retentive IT person who's being overly security conscious, or because they simply don't know any better. Even worse, they'll give you a client where this stuff can't be reconfigured.
The only way around that is to log into a local machine over the VPN, and then do everything from that system.

To be able to detect unused imports, code or variables, make sure you have this options in tsconfig.json file
"compilerOptions": {
"noUnusedLocals": true,
"noUnusedParameters": true
}
have the typescript compiler installed, ifnot install it with:
npm install -g typescript
and the tslint extension installed in Vcode, this worked for me, but after enabling I notice an increase amount of CPU usage, specially on big projects.
I would also recomend using typescript hero extension for organizing your imports.

Im my case i was using Git Credential Manager for Windows (it was installed by default, I didn't install it manually)
Credentials Manager had saved my old password but i changed it lately.
If you are in the same conditions, to solve this problem: Go to Control Panel -> Credentials Manager and delete git account. After that it will ask you again for the credentials.
Use .onkeydown
and cancel the removing with return false;
. Like this:
var input = document.getElementById('myInput');
input.onkeydown = function() {
var key = event.keyCode || event.charCode;
if( key == 8 || key == 46 )
return false;
};
Or with jQuery, because you added a jQuery tag to your question:
jQuery(function($) {
var input = $('#myInput');
input.on('keydown', function() {
var key = event.keyCode || event.charCode;
if( key == 8 || key == 46 )
return false;
});
});

numpy.ndarray()
is a class, while numpy.array()
is a method / function to create ndarray
.
In numpy docs if you want to create an array from ndarray
class you can do it with 2 ways as quoted:
1- using array()
, zeros()
or empty()
methods:
Arrays should be constructed using array, zeros or empty (refer to the See Also section below). The parameters given here refer to a low-level method (ndarray(…)
) for instantiating an array.
2- from ndarray
class directly:
There are two modes of creating an array using __new__
:
If buffer is None, then only shape, dtype, and order are used.
If buffer is an object exposing the buffer interface, then all keywords are interpreted.
The example below gives a random array because we didn't assign buffer value:
np.ndarray(shape=(2,2), dtype=float, order='F', buffer=None) array([[ -1.13698227e+002, 4.25087011e-303], [ 2.88528414e-306, 3.27025015e-309]]) #random
another example is to assign array object to the buffer example:
>>> np.ndarray((2,), buffer=np.array([1,2,3]), ... offset=np.int_().itemsize, ... dtype=int) # offset = 1*itemsize, i.e. skip first element array([2, 3])
from above example we notice that we can't assign a list to "buffer" and we had to use numpy.array() to return ndarray object for the buffer
Conclusion: use numpy.array()
if you want to make a numpy.ndarray()
object"
looks good enough as a generic version. You can modify it to meet your needs, if they're specific enough.
also test for exceptions and error conditions, such as file doesn't exist or can't be read, etc.
you can also do the following to save some space:
byte[] bytes = System.IO.File.ReadAllBytes(filename);

Swift 3/4 with @IBDesignable
While almost all the above solutions work fine but I would suggest an @IBDesignable
custom class for this.
@IBDesignable
class CustomLabel: UILabel {
/*
// Only override draw() if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
override func draw(_ rect: CGRect) {
// Drawing code
}
*/
@IBInspectable var borderColor: UIColor = UIColor.white {
didSet {
layer.borderColor = borderColor.cgColor
}
}
@IBInspectable var borderWidth: CGFloat = 2.0 {
didSet {
layer.borderWidth = borderWidth
}
}
@IBInspectable var cornerRadius: CGFloat = 0.0 {
didSet {
layer.cornerRadius = cornerRadius
}
}
}
You can try changing it to this:
If myTableData.Rows.Count > 0 Then
For i As Integer = 0 To myTableData.Rows.Count - 1
''Dim DataType() As String = myTableData.Rows(i).Item(1)
ListBox2.Items.Add(myTableData.Rows(i)(1))
Next
End If
Note: Your loop needs to be one less than the row count since it's a zero-based index.
IE 5 through 8 has a bug where using delete on properties of a host object (Window, Global, DOM etc) throws TypeError "object does not support this action".
var el=document.getElementById("anElementId");
el.foo = {bar:"baz"};
try{
delete el.foo;
}catch(){
//alert("Curses, drats and double double damn!");
el.foo=undefined; // a work around
}
Later if you need to check where the property has a meaning full value use el.foo !== undefined
because "foo" in el
will always return true in IE.
If you really need the property to really disappear...
function hostProxy(host){
if(host===null || host===undefined) return host;
if(!"_hostProxy" in host){
host._hostproxy={_host:host,prototype:host};
}
return host._hostproxy;
}
var el=hostProxy(document.getElementById("anElementId"));
el.foo = {bar:"baz"};
delete el.foo; // removing property if a non-host object
if your need to use the host object with host api...
el.parent.removeChild(el._host);

Another solution to pass DateTime from C# to SQL Server, irrespective of SQL Server language settings
supposedly that your Regional Settings show date as dd.MM.yyyy (German standard '104') then
DateTime myDateTime = DateTime.Now;
string sqlServerDate = "CONVERT(date,'"+myDateTime+"',104)";
passes the C# datetime variable to SQL Server Date type variable, considering the mapping as per "104" rules . Sql Server date gets yyyy-MM-dd
If your Regional Settings display DateTime differently, then use the appropriate matching from the SQL Server CONVERT Table

Angular 4 to 8
Either works
<img [src]="imageSrc" [alt]="imageAlt" />
<img src="{{imageSrc}}" alt="{{imageAlt}}" />
and the Component would be
export class sample Component implements OnInit {

imageAlt = 'iPhone'
Tree structure:

-> app
-> assets
-> images
'iphone.png'
You want your if
check to be:
{% if not loop.last %}
,
{% endif %}
Note that you can also shorten the code by using If Expression:
{{ ", " if not loop.last else "" }}

A few years ago I had same question, took a folder structure but had to do a lot directory moving later on, because the folder was meant for a different purpose than that I have read on internet, that is, what a particular folder does has different meanings for different people on some folders.
Now, having done multiple projects, in addition to explanation in all other answers, on the folder structure itself, I would strongly suggest to follow the structure of Node.js itself, which can be seen at: https://github.com/nodejs/node. It has great detail on all, say linters and others, what file and folder structure they have and where. Some folders have a README that explains what is in that folder.
Starting in above structure is good because some day a new requirement comes in and but you will have a scope to improve as it is already followed by Node.js itself which is maintained over many years now.
Hope this helps.
How about adding one extra decimal that is to be rounded and then discarded:
var d = 0.241534545765;
var result1 = d.ToString("0.###%");
var result2 = result1.Remove(result1.Length - 1);
If event is attached this way, and the target is to be unattached:
$('#container').on('click','span',function(eo){
alert(1);
$(this).off(); //seams easy, but does not work
$('#container').off('click','span'); //clears click event for every span
$(this).on("click",function(){return false;}); //this works.
});?
You have to convert string formate to required date format as following and then you can get your required result.
hive> select * from salesdata01 where from_unixtime(unix_timestamp(Order_date, 'dd-MM-yyyy'),'yyyy-MM-dd') >= from_unixtime(unix_timestamp('2010-09-01', 'yyyy-MM-dd'),'yyyy-MM-dd') and from_unixtime(unix_timestamp(Order_date, 'dd-MM-yyyy'),'yyyy-MM-dd') <= from_unixtime(unix_timestamp('2011-09-01', 'yyyy-MM-dd'),'yyyy-MM-dd') limit 10;

Yes, you can program Android apps in C++ (for the most part), using the Native Development Kit (NDK), although Java is the primary/preferred language for programming Android, and your C++ code will likely have to interface with Java components, and you'll likely need to read and understand the documentation for Java components, as well. Therefore, I'd advise you to use Java unless you have some existing C++ code base that you need to port and that isn't practical to rewrite in Java.
Java is very similar to C++, I don't think you will have any problems picking it up... going from C++ to Java is incredibly easy; going from Java to C++ is a little more difficult, though not terrible. Java for C++ Programmers does a pretty good job at explaining the differences. Writing your Android code in Java will be more idiomatic and will also make the development process easier for you (as the tooling for the Java Android SDK is significantly better than the corresponding NDK tooling)
In terms of setup, Google provides the Android Studio IDE for both Java and C++ Android development (with Gradle as the build system), but you are free to use whatever IDE or build system you want so long as, under the hood, you are using the Android SDK / NDK to produce the final outputs.
Something I completely missed: the non-wrapping behaviour of <pre>
can be controlled with CSS. So this gives the exact result I was looking for:
code { _x000D_
background: hsl(220, 80%, 90%); _x000D_
}_x000D_
_x000D_
pre {_x000D_
white-space: pre-wrap;_x000D_
background: hsl(30,80%,90%);_x000D_
}
_x000D_
Here's an example demonstrating the <code><code></code> tag._x000D_
_x000D_
<pre>_x000D_
Here's a very long pre-formatted formatted using the <pre> tag. Notice how it wraps? It goes on and on and on and on and on and on and on and on and on and on..._x000D_
</pre>
_x000D_
Having the following XML:
<node>Text1<subnode/>text2</node>
How do I select either the first or the second text node via XPath?
Use:
/node/text()
This selects all text-node children of the top element (named "node") of the XML document.
/node/text()[1]
This selects the first text-node child of the top element (named "node") of the XML document.
/node/text()[2]
This selects the second text-node child of the top element (named "node") of the XML document.
/node/text()[someInteger]
This selects the someInteger-th text-node child of the top element (named "node") of the XML document. It is equivalent to the following XPath expression:
/node/text()[position() = someInteger]
This problem isn't caused by missing tab stops; it's that emacs has a (new?) tab method called indent-relative that seems designed to line up tabular data. The TAB key is mapped to the method indent-for-tab-command, which calls whatever method the variable indent-line-function is set to, which is indent-relative method for text mode. I havn't figured out a good way to override the indent-line-function variable (text mode hook isn't working, so maybe it is getting reset after the mode-hooks run?) but one simple way to get rid of this behavior is to just chuck the intent-for-tab-command method by setting TAB to the simpler tab-to-tab-stop method:
(define-key text-mode-map (kbd "TAB") 'tab-to-tab-stop)
Use below command to create a package.json file.
npm init
npm init --yes or -y flag
[This method will generate a default package.json using information extracted from the current directory.]
Change the checkboxes so that the name includes the index inside the brackets:
<input type="checkbox" class="checkbox_veh" id="checkbox_addveh<?php echo $i; ?>" <?php if ($vehicle_feature[$i]->check) echo "checked"; ?> name="feature[<?php echo $i; ?>]" value="<?php echo $vehicle_feature[$i]->id; ?>">
The checkboxes that aren't checked are never submitted. The boxes that are checked get submitted, but they get numbered consecutively from 0, and won't have the same indexes as the other corresponding input fields.
99% of the time I would use XMLHttpRequest or fetch for something like this. However, there's an alternative solution which doesn't require javascript...
You could include a hidden iframe on your page and set the target attribute of your form to point to that iframe.
<style>
.hide { position:absolute; top:-1px; left:-1px; width:1px; height:1px; }
</style>
<iframe name="hiddenFrame" class="hide"></iframe>
<form action="receiver.pl" method="post" target="hiddenFrame">
<input name="signed" type="checkbox">
<input value="Save" type="submit">
</form>
There are very few scenarios where I would choose this route. Generally handling it with javascript is better because, with javascript you can...
You just need to add 'table-layout: fixed;'
.table {
display: table;
height: 100px;
width: 100%;
table-layout: fixed;
}
Try something like this
select Cast((SPGI09_EARLY_OVER_T – (SPGI09_OVER_WK_EARLY_ADJUST_T) / (SPGI09_EARLY_OVER_T + SPGR99_LATE_CM_T + SPGR99_ON_TIME_Q)) as varchar(20) + '%' as percentageAmount
from CSPGI09_OVERSHIPMENT
I presume the value is a representation in percentage - if not convert it to a valid percentage total, then add the % sign and convert the column to varchar.
You should be referencing Selected
not ids.Contains
as the last line.
I just realized this is a formatting issue, from the OP. Regardless you should be referencing the value in Selected. I recommend adding some Console.WriteLine calls to see exactly what is being printed out on each line and also what each value is.
After your update: ids is an empty list, how is this not throwing a NullReferenceException? As it was never initialized in that code block
You can also install it using conda (tested on Ubuntu):
conda create --name csharp
conda activate csharp
conda install -c conda-forge mono
query for row_number in mysql
set @row_number=0;
select (@row_number := @row_number +1) as num,id,name from sbs
package com.raj.samplestring;
/**
* @author gnagara
*/
public class SampleString {
/**
* @param args
*/
public static void main(String[] args) {
String[] stringArray;
String givenString = "ramu is Arr Good boy";
stringArray = givenString.split(" ");
for(int i=0; i<stringArray.length;i++){
if(!Character.isUpperCase(stringArray[i].charAt(0))){
Character c = stringArray[i].charAt(0);
Character change = Character.toUpperCase(c);
StringBuffer ss = new StringBuffer(stringArray[i]);
ss.insert(0, change);
ss.deleteCharAt(1);
stringArray[i]= ss.toString();
}
}
for(String e:stringArray){
System.out.println(e);
}
}
}

I had the same problem. I ran my Docker image, and it created a container with a specific CONTAINER_ID. I wanted to work with the same container:
First run your Docker image:
docker run -it -p 8888:8888 -p 6006:6006 -v ~/:/host waleedka/modern-deep-learning
Then list all the containers you have made:
sudo docker ps -a
And select the container you want to work with (mine is 167ddd6d7f15):
sudo docker start -ai 167ddd6d7f15
outgoing url in mvc generated based on the current routing schema.
because your Information action method require id parameter, and your route collection has id of your current requested url(/Admin/Information/5), id parameter automatically gotten from existing route collection values.
to solve this problem you should use UrlParameter.Optional:
<a href="@Url.Action("Information", "Admin", new { id = UrlParameter.Optional })">Add an Admin</a>
This is because you DON'T associated the OnClickListener() on the button retrieve from the XML layout.
You don't need to create object because they are already created by the Android system when you inflate XML file (with the Activity.setContentLayout( int resourceLayoutId ) method).
Just retrieve them with the findViewById(...) method.
Since inline events are executed as functions you can simply use arguments.
<p id="p" onclick="doSomething.apply(this, arguments)">
and
function doSomething(e) {
if (!e) e = window.event;
// 'e' is the event.
// 'this' is the P element
}
The 'event' that is mentioned in the accepted answer is actually the name of the argument passed to the function. It has nothing to do with the global event.
You are not comparing dates. You are comparing strings. In the world of string comparisons, 09/17/2015
> 01/02/2016
because 09
> 01
. You need to either put your date in a comparable string format or compare DateTime
objects which are comparable.
<?php
$date_now = date("Y-m-d"); // this format is string comparable
if ($date_now > '2016-01-02') {
echo 'greater than';
}else{
echo 'Less than';
}
Or
<?php
$date_now = new DateTime();
$date2 = new DateTime("01/02/2016");
if ($date_now > $date2) {
echo 'greater than';
}else{
echo 'Less than';
}
Through the UI in SQL Server 2005 manager, change the column remove the autonumber (identity) property of the column (select the table by right clicking on it and choose "Design").
Then run your query:
UPDATE table SET Id = Id + 1
Then go and add the autonumber property back to the column.
If you are running ZSH shell in MacOS you should rerun the installation and when you be asked for this question:

In my case I have just changed the .navbar
min-height
and the links font-size
and it decreased the navbar.
For example:
.navbar{
min-height:12px;
}
.navbar a {
font-size: 11.2px;
}
And this also worked for increasing the navbar height.
This also helps to change the navbar size when scrolling down the browser.
You are asking for the condition where all the conditions are true, so len of the frame is the answer, unless I misunderstand what you are asking

The solution mentioned in ".gitignore file not ignoring" is a bit extreme, but should work:
# rm all files
git rm -r --cached .
# add all files as per new .gitignore
git add .
# now, commit for new .gitignore to apply
git commit -m ".gitignore is now working"
(make sure to commit first your changes you want to keep, to avoid any incident as jball037 comments below.
The --cached
option will keep your files untouched on your disk though.)
You also have other more fine-grained solution in the blog post "Making Git ignore already-tracked files":
git rm --cached `git ls-files -i --exclude-standard`
Bassim suggests in his edit:
In case you get an error message like
fatal: path spec '...' did not match any files
, there might be files with spaces in their path.You can remove all other files with option
--ignore-unmatch
:
git rm --cached --ignore-unmatch `git ls-files -i --exclude-standard`
but unmatched files will remain in your repository and will have to be removed explicitly by enclosing their path with double quotes:
git rm --cached "<path.to.remaining.file>"
Sounds like you really want a Dictionary<int, string>
or possibly a switch
statement...
You can do it with the conditional operator though:
userType = user.Type == 0 ? "Admin"
: user.Type == 1 ? "User"
: user.Type == 2 ? "Employee"
: "The default you didn't specify";
While you could put that in one line, I'd strongly urge you not to.
I would normally only do this for different conditions though - not just several different possible values, which is better handled in a map.
You might want to have a look at this specification for CSV. Bear in mind that there is no official recognized specification.
If you do not now the delimiter it will not be possible to do this so you have to find out somehow. If you can do a manual inspection of the file you should quickly be able to see what it is and hard code it in your program. If the delimiter can vary your only hope is to be able to deduce if from the formatting of the known data. When Excel imports CSV files it lets the user choose the delimiter and this is a solution you could use as well.
You can achieve what you want with the padding-bottom: 100%; margin-bottom: -100%;
trick, has you can see in this fiddle.
I change your HTML a little bit, but you can achieve the same result with your own HTML with the following code
.col-md-9 {
overflow: hidden;
}
.col-md-3 {
padding-bottom: 100%;
margin-bottom: -100%;
}
Normally i use a class for this:
public class ClassName
{
public string Col1 { get; set; }
public int Col2 { get; set; }
}
Now you can use a loop to fill a list and ToArray
if you really need an array:
ClassName[] allRecords = null;
string sql = @"SELECT col1,col2
FROM some table";
using (var command = new SqlCommand(sql, con))
{
con.Open();
using (var reader = command.ExecuteReader())
{
var list = new List<ClassName>();
while (reader.Read())
list.Add(new ClassName { Col1 = reader.GetString(0), Col2 = reader.GetInt32(1) });
allRecords = list.ToArray();
}
}
Note that i've presumed that the first column is a string
and the second an integer
. Just to demonstrate that C# is typesafe and how you use the DataReader.GetXY
methods.

The solution takes two steps!
First, complete the user, domain, and proxy fields in cntlm.ini
. The username and domain should probably be whatever you use to log in to Windows at your office, eg.
Username employee1730
Domain corporate
Proxy proxy.infosys.corp:8080
Then test cntlm with a command such as
cntlm.exe -c cntlm.ini -I -M http://www.bbc.co.uk
It will ask for your password (again whatever you use to log in to Windows_). Hopefully it will print 'http 200 ok' somewhere, and print your some cryptic tokens authentication information. Now add these to cntlm.ini
, eg:
Auth NTLM
PassNT A2A7104B1CE00000000000000007E1E1
PassLM C66000000000000000000000008060C8
Finally, set the http_proxy
environment variable in Windows (assuming you didn't change with the Listen
field which by default is set to 3128
) to the following
http://localhost:3128
To start redis with a config file all you need to do is specifiy the config file as an argument:
redis-server /root/config/redis.rb
Instead of using and killing PID's I would suggest creating an init script for your service
I would suggest taking a look at the Installing Redis more properly section of http://redis.io/topics/quickstart. It will walk you through setting up an init script with redis so you can just do something like service redis_server start
and service redis_server stop
to control your server.
I am not sure exactly what distro you are using, that article describes instructions for a Debian based distro. If you are are using a RHEL/Fedora distro let me know, I can provide you with instructions for the last couple of steps, the config file and most of the other steps will be the same.
You've misunderstood how character classes are used:
$varTemp =~ s/[\$#@~!&*()\[\];.,:?^ `\\\/]+//g;
does the same as your regex (assuming you didn't mean to remove '
characters from your strings).
Edit: The +
allows several of those "special characters" to match at once, so it should also be faster.
You might want colored output with this.
I use this one-liner for listing the tracked files and directories in the current directory of the current branch:
ls --group-directories-first --color=auto -d $(git ls-tree $(git branch | grep \* | cut -d " " -f2) --name-only)
You might want to add it as an alias:
alias gl='ls --group-directories-first --color=auto -d $(git ls-tree $(git branch | grep \* | cut -d " " -f2) --name-only)'
If you want to recursively list files:
'ls' --color=auto -d $(git ls-tree -rt $(git branch | grep \* | cut -d " " -f2) --name-only)
And an alias:
alias glr="'ls' --color=auto -d \$(git ls-tree -rt \$(git branch | grep \\* | cut -d \" \" -f2) --name-only)"
My underlying APIs were all using cents to represent money, and I didn't want to change that. Nor was I working with large amounts of money. So I just put this in a helper method:
sprintf("%03d", amount).insert(-3, ".")
That converts the integer to a string with at least three digits (adding leading zeroes if necessary), then inserts a decimal point before the last two digits, never using a Float
. From there you can add whatever currency symbols are appropriate for your use case.
It's definitely quick and dirty, but sometimes that's just fine!
To improve on Forumpie's answer, the trick is using %*
(all params) in the sub:
Edit: Added echo of the TRIM subroutines params, to provide more insight
@ECHO OFF
SET /p NAME=- NAME ?
ECHO "%NAME%"
CALL :TRIM %NAME%
SET NAME=%TRIMRESULT%
ECHO "%NAME%"
GOTO :EOF
:TRIM
echo "%1"
echo "%2"
echo "%3"
echo "%4"
SET TRIMRESULT=%*
GOTO :EOF
This strips leading and trailing spaces, but keeps all spaces between.
" 1 2 3 4 "
"1 2 3 4"

A variable cannot be both null
and undefined
at the same time. However, the direct answer to your question is:
if (variable != null)
One =
, not two.
There are two special clauses in the "abstract equality comparison algorithm" in the JavaScript spec devoted to the case of one operand being null
and the other being undefined
, and the result is true
for ==
and false
for !=
. Thus if the value of the variable is undefined
, it's not != null
, and if it's not null, it's obviously not != null
.
Now, the case of an identifier not being defined at all, either as a var
or let
, as a function parameter, or as a property of the global context is different. A reference to such an identifier is treated as an error at runtime. You could attempt a reference and catch the error:
var isDefined = false;
try {
(variable);
isDefined = true;

I would personally consider that a questionable practice however. For global symbols that may or may be there based on the presence or absence of some other library, or some similar situation, you can test for a window
property (in browser JavaScript):
var isJqueryAvailable = window.jQuery != null;
or
var isJqueryAvailable = "jQuery" in window;
you can wrap -Andrie answer into a generic function
mbind<-function(...){
Reduce( function(x,y){cbind(x,y[match(row.names(x),row.names(y)),])}, list(...) )
}
Here, you can bind multiple frames with rownames as key
This works for me. Hope it will work for you too.

They are not null if you don't initialize the struct.
Snapshot s; // receives no initialization
Snapshot s = {}; // value initializes all members
The second will make all members zero, the first leaves them at unspecified values. Note that it is recursive:
struct Parent { Snapshot s; };
Parent p; // receives no initialization
Parent p = {}; // value initializes all members
The second will make p.s.{x,y}
zero. You cannot use these aggregate initializer lists if you've got constructors in your struct. If that is the case, you will have to add proper initalization to those constructors
struct Snapshot {
int x;
double y;
Snapshot():x(0),y(0) { }
// other ctors / functions...
};
Will initialize both x and y to 0. Note that you can use x(), y()
to initialize them disregarding of their type: That's then value initialization, and usually yields a proper initial value (0 for int, 0.0 for double, calling the default constructor for user defined types that have user declared constructors, ...). This is important especially if your struct is a template.

Technical Article on How java is platform indepedent?
Before going into the detail,first you have to understand what is the mean of platform? Platform consists of the computer hardware(mainly architecture of the microprocessor) and OS. Platform=hardware+Operating System
Anything that is platform indepedent can run on any operating system and hardware.
Java is platform indepedent so java can run on any operating system and hardware. Now question is how is it platform independent?
This is because of the magic of Byte Code which is OS indepedent. When java compiler compiles any code then it generates the byte code not the machine native code(unlike C compiler). Now this byte code needs an interpreter to execute on a machine. This interpreter is JVM. So JVM reads that byte code(that is machine indepedent) amd execute it. Different JVM is designed for different OS and byte code is able to run on different OS.
In case of C or C++(language that are not platform indepedent) compiler generate the .exe file that is OS depedent so when we run this .exe file on another OS it will not run because this file is OS depedent so is not compatible with the another OS.
Finally an intermediate OS indepedent Byte code make the java platform independent.
You can use another overload of the DropDownList
method. Pick the one you need and pass in
a object with your html attributes.
@Html.DropDownList("CategoryID", null, new { @onchange="location = this.value;" })
I use the IntelliJ one, because I'm mostly concerned with IntelliJ flagging things that might produce a NPE. I agree that it's frustrating not having a standard annotation in the JDK. There's talk of adding it, it might make it into Java 7. In which case there will be one more to choose from!
In vue-cli version 3:
There are the three options for .env files:
Either you can use .env
or:
.env.test
.env.development
.env.production
You can use custom .env
variables by using the prefix regex as /^/
instead of /^VUE_APP_/
in /node_modules/@vue/cli-service/lib/util/resolveClientEnv.js:prefixRE
This is certainly not recommended for the sake of developing an open source app in different modes like test, development, and production of .env
files. Because every time you npm install ..
, it will be overridden.
If you're looking for a particular string, put quotes around it:
awk '$1 == "findtext" {print $3}'
Otherwise, awk will assume it's a variable name.
I found that the line, VisualTreeHelper.GetChildrenCount(depObj);
, used in several examples above does not return a non-zero count for GroupBox
es, in particular, where the GroupBox
contains a Grid
, and the Grid
contains children elements. I believe this may be because the GroupBox
is not allowed to contain more than one child, and this is stored in its Content
property. There is no GroupBox.Children
type of property. I am sure I did not do this very efficiently, but I modified the first "FindVisualChildren" example in this chain as follows:
public IEnumerable<T> FindVisualChildren<T>(DependencyObject depObj) where T : DependencyObject
{
if (depObj != null)
{
int depObjCount = VisualTreeHelper.GetChildrenCount(depObj);
for (int i = 0; i <depObjCount; i++)
{
DependencyObject child = VisualTreeHelper.GetChild(depObj, i);
if (child != null && child is T)
{
yield return (T)child;
}
if (child is GroupBox)
{
GroupBox gb = child as GroupBox;
Object gpchild = gb.Content;
if (gpchild is T)
{
yield return (T)child;
child = gpchild as T;
}
}
foreach (T childOfChild in FindVisualChildren<T>(child))
{
yield return childOfChild;
}
}
}
}
For Windows users, Ruby doesn't set up .gemrc file. So you have to create .gemrc file in your home directory (echo %USERPROFILE%
) and put following line in it:
gem: --no-document
As already mentioned in previous answers, don't use --no-ri and --no-rdoc cause its deprecated. See it yourself:
gem help install
try this. Based on what type of output you want. sometime you may not need single quote around printed string.
test = "qweqwe\n1212as\t121\\2asas"
print(repr(test)) # output: 'qweqwe\n1212as\t121\\2asas'
print( repr(test).strip("'")) # output: qweqwe\n1212as\t121\\2asas
None has worked for me. But his one did.
Since the Bootstrap 4 .row class is now display:flex you can simply use the new align-self-center flexbox utility on any column to vertically center it:
<div class="row">
<div class="col-6 align-self-center">
<div class="card card-block">
Center
</div>
</div>
<div class="col-6">
<div class="card card-inverse card-danger">
Taller
</div>
</div>
</div>
I learned about it from https://medium.com/wdstack/bootstrap-4-vertical-center-1211448a2eff
From the pthread function prototype:
int pthread_create(pthread_t *thread, const pthread_attr_t *attr,
void *(*start_routine)(void*), void *arg);
The function passed to pthread_create must have a prototype of
void* name(void *arg)
If the attribute you want to sort by is a property, then you can avoid importing operator.attrgetter
and use the property's fget
method instead.
For example, for a class Circle
with a property radius
we could sort a list of circles
by radii as follows:
result = sorted(circles, key=Circle.radius.fget)
This is not the most well-known feature but often saves me a line with the import.
There are almost no good reasons for not using Optional
as parameters. The arguments against this rely on arguments from authority (see Brian Goetz - his argument is we can't enforce non null optionals) or that the Optional
arguments may be null (essentially the same argument). Of course, any reference in Java can be null, we need to encourage rules being enforced by the compiler, not programmers memory (which is problematic and does not scale).
Functional programming languages encourage Optional
parameters. One of the best ways of using this is to have multiple optional parameters and using liftM2
to use a function assuming the parameters are not empty and returning an optional (see http://www.functionaljava.org/javadoc/4.4/functionaljava/fj/data/Option.html#liftM2-fj.F-). Java 8 has unfortunately implemented a very limited library supporting optional.
As Java programmers we should only be using null to interact with legacy libraries.
There is no WPF equivalent. System.Windows.Forms.Screen
is still part of the .NET framework and can be used from WPF though.
See this question for more details, but you can use the calls relating to screens by using the WindowInteropHelper
class to wrap your WPF control.
On rails 4.2.2, go to application.rb
and use config.time_zone='city'
(e.g.:'London' or 'Bucharest' or 'Amsterdam' and so on).
It should work just fine. It worked for me.

Why does it take three branches/merges for every task? Can you explain more about that?
If you use a bug tracking system you can use the bug number as part of the branch name. This will keep the branch names unique, and you can prefix them with a short and descriptive word or two to keep them human readable, like "ResizeWindow-43523"
. It also helps make things easier when you go to clean up branches, since you can look up the associated bug. This is how I usually name my branches.
Since these branches are eventually getting merged back into master, you should be safe deleting them after you merge. Unless you're merging with --squash
, the entire history of the branch will still exist should you ever need it.
From GC Performance Tuning training documents of Oracle:
-Xmn[size]: Size of young generation heap space.
Applications with emphasis on performance tend to use -Xmn to size the young generation, because it combines the use of -XX:MaxNewSize and -XX:NewSize and almost always explicitly sets -XX:PermSize and -XX:MaxPermSize to the same value.
In short, it sets the NewSize and MaxNewSize values of New generation to the same value.
This is what helped me:
Create a new branch with the existing one. Let's call the existing one branch_old
and new as branch_new
.
Reset branch_new
to a stable state, when you did not have any problem commit at all.
For example, to put it at your local master's level do the following:
git reset —hard master git push —force origin
cherry-pick
the commits from branch_old
into branch_new
git push
Try this one:
<button class="button" onclick="$('#target').toggle();">
Show/Hide
</button>
<div id="target" style="display: none">
Hide show.....
</div>
Just check the length of the selector, if it more than 0 then it's return true otherwise false.
For ID:
if( $('#selector').length ) // use this if you are using id to check

// it exists

For Class:
if( $('.selector').length ) // use this if you are using class to check
{
// it exists
}
For Dropdown:
if( $('#selector option').size() ) { // use this if you are using dropdown size to check
// it exists
}

Here is what I used for TSQL which took care of the problem that my table name could contain the schema name and possibly the database name:
DECLARE @THETABLE varchar(100);
SET @THETABLE = 'theschema.thetable';
select i.*
from sys.indexes i
where i.object_id = OBJECT_ID(@THETABLE)
and i.name is not NULL;
The use case for this is that I wanted the list of indexes for a named table so I could write a procedure that would dynamically compress all indexes on a table.
The second approach is right to execute JavaScript code after the page has finished loading - but you don't actually execute JavaScript code there, you inserted plain HTML.
The first thing works, but loads the JavaScript immediately and clears the page (so your tag will be there - but nothing else).
(Plus: language="javascript" has been deprecated for years, use type="text/javascript" instead!)
To get that working, you have to use the DOM manipulating methods included in JavaScript. Basically you'll need something like this:
var scriptElement=document.createElement('script');
scriptElement.type = 'text/javascript';
scriptElement.src = filename;
document.head.appendChild(scriptElement);

Please copy the below code into any module, save the workbook and then run the code.
Here is what code does
The sample subroutine sets the folder path & later the file path. Kindly set them accordingly before you run the code.
I have added a function IsWorkBookOpen to check if workbook is already then set the workbook variable the workbook name else open the workbook which will be assigned to workbook variable accordingly.
Dim wbA As Workbook
Dim wbB As Workbook
Sub MySubRoutine()
Dim folderPath As String, fileNm1 As String, fileNm2 As String, filePath1 As String, filePath2 As String
folderPath = ThisWorkbook.Path & "\"
fileNm1 = "file1.xlsx"
fileNm2 = "file2.xlsx"
filePath1 = folderPath & fileNm1
filePath2 = folderPath & fileNm2
If IsWorkBookOpen(filePath1) Then
Set wbA = Workbooks(fileNm1)
Else
Set wbA = Workbooks.Open(filePath1)
End If
If IsWorkBookOpen(filePath2) Then
Set wbB = Workbooks.Open(fileNm2)
Else
Set wbB = Workbooks.Open(filePath2)
End If
' your code here
End Sub
Function IsWorkBookOpen(FileName As String)
Dim ff As Long, ErrNo As Long
On Error Resume Next
ff = FreeFile()
Open FileName For Input Lock Read As #ff
Close ff
ErrNo = Err
On Error GoTo 0
Select Case ErrNo
Case 0: IsWorkBookOpen = False
Case 70: IsWorkBookOpen = True
Case Else: Error ErrNo
End Select
End Function
Using Prompt to select the file use below code.
Dim wbA As Workbook
Dim wbB As Workbook
Sub MySubRoutine()

'reset the variable
filePath = vbNullString
cmdBrowse_Click filePath, 2
filePath2 = filePath
fileNm1 = GetFileName(filePath1, "\")
fileNm2 = GetFileName(filePath2, "\")
If IsWorkBookOpen(filePath1) Then
Set wbA = Workbooks(fileNm1)
Else
Set wbA = Workbooks.Open(filePath1)
End If
If IsWorkBookOpen(filePath2) Then
Set wbB = Workbooks.Open(fileNm2)
Else
Set wbB = Workbooks.Open(filePath2)
End If
' your code here
End Sub
Function IsWorkBookOpen(FileName As String)
Dim ff As Long, ErrNo As Long
On Error Resume Next
ff = FreeFile()
Open FileName For Input Lock Read As #ff

Whenever I have a class that contains a nested class that is of any significant size/complexity, I mark the class as partial
and put the nested class in a separate file. I name the file containing the nested class using the rule: [class name].[nested class name].cs.
The following MSDN blog explains using partial classes with nested classes for maintainability: http://blogs.msdn.com/b/marcelolr/archive/2009/04/13/using-partial-classes-with-nested-classes-for-maintainability.aspx
You can have two different versions of XAMPP.
You could use \r\n

Remember that your img is not really a DOM element but a javascript expression.
This is a JSX attribute expression. Put curly braces around the src string expression and it will work. See http://facebook.github.io/react/docs/jsx-in-depth.html#attribute-expressions
In javascript, the class attribute is reference using className. See the note in this section: http://facebook.github.io/react/docs/jsx-in-depth.html#react-composite-components
/** @jsx React.DOM */
var Hello = React.createClass({
render: function() {
return <div><img src={'http://placehold.it/400x20&text=slide1'} alt="boohoo" className="img-responsive"/><span>Hello {this.props.name}</span></div>;
}
});
React.renderComponent(<Hello name="World" />, document.body);

If you want to find elapsed time, this method will work as long as you don't reboot the computer between the start and end.
In Windows, use GetTickCount(). Here's how:
DWORD dwStart = GetTickCount();
...
... process you want to measure elapsed time for
...
DWORD dwElapsed = GetTickCount() - dwStart;
dwElapsed is now the number of elapsed milliseconds.
In Linux, use clock() and CLOCKS_PER_SEC to do about the same thing.
If you need timestamps that last through reboots or across PCs (which would need quite good syncronization indeed), then use the other methods (gettimeofday()).
Also, in Windows at least you can get much better than standard time resolution. Usually, if you called GetTickCount() in a tight loop, you'd see it jumping by 10-50 each time it changed. That's because of the time quantum used by the Windows thread scheduler. This is more or less the amount of time it gives each thread to run before switching to something else. If you do a:
timeBeginPeriod(1);
at the beginning of your program or process and a:
timeEndPeriod(1);
at the end, then the quantum will change to 1 ms, and you will get much better time resolution on the GetTickCount() call. However, this does make a subtle change to how your entire computer runs processes, so keep that in mind. However, Windows Media Player and many other things do this routinely anyway, so I don't worry too much about it.
I'm sure there's probably some way to do the same in Linux (probably with much better control, or maybe with sub-millisecond quantums) but I haven't needed to do that yet in Linux.

The simple solution is to just remap coordinates from the original to the final image, copying pixels from one coordinate space to the other, rounding off as necessary -- which may result in some pixels being copied several times adjacent to each other, and other pixels being skipped, depending on whether you're stretching or shrinking (or both) in either dimension. Make sure your copying iterates through the destination space, so all pixels are covered there even if they're painted more than once, rather than thru the source which may skip pixels in the output.
The better solution involves calculating the corresponding source coordinate without rounding, and then using its fractional position between pixels to compute an appropriate average of the (typically) four pixels surrounding that location. This is essentially a filtering operation, so you lose some resolution -- but the result looks a LOT better to the human eye; it does a much better job of retaining small details and avoids creating straight-line artifacts which humans find objectionable.
Note that the same basic approach can be used to remap flat images onto any other shape, including 3D surface mapping.
Reply to MVC4 DataType.Date EditorFor won't display date value in Chrome, fine in IE
In the Model you need to have following type of declaration:
[DataType(DataType.Date)]
public DateTime? DateXYZ { get; set; }
OR
[DataType(DataType.Date)]
public Nullable<System.DateTime> DateXYZ { get; set; }
You don't need to use following attribute:
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
At the Date.cshtml use this template:
@model Nullable<DateTime>
@using System.Globalization;
@{
DateTime dt = DateTime.Now;
if (Model != null)
{
dt = (System.DateTime)Model;
}
if (Request.Browser.Type.ToUpper().Contains("IE") || Request.Browser.Type.Contains("InternetExplorer"))
{
@Html.TextBox("", String.Format("{0:d}", dt.ToShortDateString()), new { @class = "datefield", type = "date" })
}
else
{
//Tested in chrome
DateTimeFormatInfo dtfi = CultureInfo.CreateSpecificCulture("en-US").DateTimeFormat;
dtfi.DateSeparator = "-";
dtfi.ShortDatePattern = @"yyyy/MM/dd";
@Html.TextBox("", String.Format("{0:d}", dt.ToString("d", dtfi)), new { @class = "datefield", type = "date" })
}
}

For those using newer versions Chart.js, you can set a label by setting the callback for tooltips.callbacks.label in options.
Example of this would be:
var chartOptions = {
tooltips: {
callbacks: {
label: function (tooltipItem, data) {
return 'label';
}
}
}
}
Here is the code that will not download courpt files

header("Content-Type: ".mime_content_type($file));
header("Content-Disposition: attachment; filename=".$filename);
while (ob_get_level()) {
ob_end_clean();
}
readfile($file);
I have included mime_content_type which will return content type of file .
To prevent from corrupt file download i have added ob_get_level() and ob_end_clean();

It is not possible to export an Android library as a jar file. It is possible, however, to export it as aar
file. Aar
files being the new binary format for Android libraries. There's info about them in Google I/O, the New Build System video.
First, build the library in Android Studio or from command line issuing gradle build
from your library's root directory.
This will result in <yourlibroot>/libs/build/yourlib.aar
file.
This aar file is a binary representation of your library and can be added to your project instead of the library as a dependency project.
To add aar file as a dependency you have to publish it to the maven central or to your local maven repository, and then refer the aar file in your project's gradle.build
file.
However, this step is a bit convoluted. I've found a good explanation how to do so here:
http://www.flexlabs.org/2013/06/using-local-aar-android-library-packages-in-gradle-builds

Note: JQuery is required.

You can't explicitly free memory. What you need to do is to make sure you don't keep references to objects. They will then be garbage collected, freeing the memory.
In your case, when you need large lists, you typically need to reorganize the code, typically using generators/iterators instead. That way you don't need to have the large lists in memory at all.

You're almost there. Although I agree with @Alex Young answer about using props for that, you simply need a reference to the instance
before trying to spy on the method.
describe('my sweet test', () => {
it('clicks it', () => {
const app = shallow(<App />)
const instance = app.instance()
const spy = jest.spyOn(instance, 'myClickFunc')
instance.forceUpdate();
const p = app.find('.App-intro')
p.simulate('click')
expect(spy).toHaveBeenCalled()
})
})

Daniel A. White Solution works great for classes.
I've got a situation where I had to find input fields like donee_1_card where 1 is an index.
My solution has been
$("input[name^='donee']" && "input[name*='card']")
Though I am not sure how optimal it is.
I know people have answered your question but in layman terms:
5 / 2 = 2
//since both 5 and 2 are integers and integers division always truncates decimals
5.0 / 2 or 5 / 2.0 or 5.0 /2.0 = 2.5
//here either 5 or 2 or both has decimal hence the quotient you will get will be in decimal.
In Python 2.7.3:
import urllib2
import socket
class MyException(Exception):
pass
try:
urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError as e:
print type(e) #not catch
except socket.timeout as e:
print type(e) #catched
raise MyException("There was an error: %r" % e)
have you tried?
<td title="This is Title">
its working fine here on Firefox v 18 (Aurora), Internet Explorer 8 & Google Chrome v 23x
I also had the same problem. And I find the solution:
CTRL+ALT+G
Update:
Thanks to @Joost, install Atom package python-tools to make it work
As of AngularJS 1.2 there's a directive called ng-repeat-start
that does exactly what you ask for. See my answer in this question for a description of how to use it.
If you have a PC with internet access in your LAN, you should install a local Maven repository.
I recommend Artifactory Open Source. This is what we use in our organization, it is really easy to setup.
Artifactory acts as a proxy between your build tool (Maven, Ant, Ivy, Gradle etc.) and the outside world.
It caches remote artifacts so that you don’t have to download them over and over again.
It blocks unwanted (and sometimes security-sensitive) external requests for internal artifacts and controls how and where artifacts are deployed, and by whom.
After setting up Artifactory you just need to change Maven's settings.xml
in the development machines:
<?xml version="1.0" encoding="UTF-8"?>
<settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd" xmlns="http://maven.apache.org/SETTINGS/1.0.0"

We used this solution because we had problems with internet access in our development machines and some artifacts downloaded corrupted files or didn't download at all. We haven't had problems since.
