...pe="text" class="resizedTextbox" />
The CSS:
.resizedTextbox {width: 100px; height: 20px}

Concurrent vs serial queues in GCD

print(i + 100)
}
for i in 1...10 {
print(i + 1000)

No matter how you configure (serial or concurrent) or dispatch (sync or async) this queue, this task will always be executed in serial. The third loop will ne...

Bash tool to get nth line from a file
...y preference using redirects, because me often used redirects like sed -n '100p' < <(some_command) - so, universal syntax :). It is NOT less effective, because redirection are done with shell when forking itself, so... it is only a preference... (and yes, it is one character longer) :)

How can I divide two integers to get a double?
...D's answer
To have a greater precision you can cast to decimal:
(decimal)100/863
//0.1158748551564310544611819235
Or:
Decimal.Divide(100, 863)
//0.1158748551564310544611819235
Double are represented allocating 64 bits while decimal uses 128
(double)100/863
//0.11587485515643106

Is it better to call ToList() or ToArray() in LINQ queries?
...g to .ToList()
foreach (var x in source)
{
if (x == 5)
source[8] *= 100;
