How to execute file I'm editing in Vi(m)
...(unix only), executes it (unix only) and redirects the output to .tmp.xyz, then creates a new tab, reads the file and then deletes it.

How to set a value to a file input in HTML?
...o the information you want to send in your code (i.e., not passwords.txt), then you can upload it as a blob-type, and then treat it as a file.
What the server will end up seeing will be indistinguishable from someone actually setting the value of <input type="file" />. The trick, ultimately,...
How to compare two NSDates: Which is more recent?
...
Let's assume two dates:
NSDate *date1;
NSDate *date2;
Then the following comparison will tell which is earlier/later/same:
if ([date1 compare:date2] == NSOrderedDescending) {
NSLog(@"date1 is later than date2");
} else if ([date1 compare:date2] == NSOrderedAscending) {

Clear file cache to repeat performance testing
...ning the file using CreateFile with the FILE_FLAG_NO_BUFFERING options and then closing the handle. This isn't documented, and I don't know if it works on later versions of Windows, but I used this long ago when writing test code to compare file compression libraries. I don't recall if read or wri...
Find a value in an array of objects in Javascript [duplicate]
...
@AaditMShah If there is no variable, then yes, that third argument can be useful. But since we have the variable in this case, there is no need for it. Regarding the second point, it’s not faster in practice. That 1-microsecond improvement isn’t even worth t...

Then, use the addr2line utility (find it in your NDK tool-chain) to find the function that crashes. In this sample, you do
addr2line -e -f libc.so 0001173c
And you will see where you got the problem. Of course this wont he...
What does it mean by buffer?
..., it's usually a single blob of memory that's loaded in one operation, and then emptied in one or more, Perchik's "candy bowl" example. In a C program, for example, you might have:
#define BUFSIZE 1024
char buffer[BUFSIZE];
size_t len = ;
// ... later
while((len=read(STDIN, &buffer, BUFSIZE))...
Canvas is stretched when using CSS but normal with “width” / “height” properties
...ues. If an attribute is missing, or if parsing its value returns an error, then the default value must be used instead. The width attribute defaults to 300, and the height attribute defaults to 150.

How to think in data stores instead of databases?
...get the notion that database size matters and data shouldn't be duplicated then you're 3/4 there and you didn't even have to write any code! Let your views dictate your Models. You don't have to take your objects and make them 2 dimensional anymore as in the relational world. You can store object...
Can you do this HTML layout without using tables?
...some obtuse CSS hackery.
If you can fit within the following constraints, then there is a relatively simple way:
The height of the two elements is fixed.
The height of the container is fixed.
The elements will be narrow enough not to overlap (or can be set to a fixed width).
Then you can use ab...
