First of all ActionScript 3 and JavaScript are both defined in ECMA-262 so they have a lot in common. Both languages feature prototype inheritance for instance. It is however not correct that ActionScript fully implements ES4. ActionScript implements a couple of features that are not defined in ECMA-262 and some — but definitely not all … Read more
Stick to pthread_cond_timedwait and use clock_gettime. For example: struct timespec ts; clock_gettime(CLOCK_REALTIME, &ts); ts.tv_sec += 10; // ten seconds while (!some_condition && ret == 0) ret = pthread_cond_timedwait(&cond, &mutex, &ts); Wrap it in a function if you wish. UPDATE: complementing the answer based on our comments. POSIX doesn’t have a single API to wait for … Read more
There’s absolutely no way you can run full-fledged WPF app on Mac. I’m not even sure if this is possible in Parallels. The best thing you can do is to use Silverlight, which was previously named “WPF/E” and does run on Macintosh.
The mempcy@GLIBC_2.14 is called a versioned symbol. Glibc uses them while other runtime libraries like musl do not. The significance of mempcy@GLIBC_2.14 when compiling on Linux is due to Glibc changing the way memcpy worked back in 2012. memcpy used to copy bytes {begin → end} (low memory address to high memory address). Glibc 2.13 … Read more
You should remove the & (ampersand) symbol, so that line 4 will look like this: $conn = ADONewConnection($config[‘db_type’]); This is because ADONewConnection already returns an object by reference. As per documentation, assigning the result of a reference to object by reference results in an E_DEPRECATED message as of PHP 5.3.0
Most of the time there is no need to use larger numeric types for simulating unsigned types in Java. For addition, subtraction, multiplication, shift left, the logical operations, equality and casting to a smaller numeric type it doesn’t matter whether the operands are signed or unsigned, the result will be the same regardless, viewed as … Read more
Try this solution based on T-SQL and XQuery((root/row)[position() <= sql:variable(“@count”)]): T-SQL Scalar function: CREATE FUNCTION dbo.SUBSTRING_INDEX ( @str NVARCHAR(4000), @delim NVARCHAR(1), @count INT ) RETURNS NVARCHAR(4000) WITH SCHEMABINDING BEGIN DECLARE @XmlSourceString XML; SET @XmlSourceString = (SELECT N'<root><row>’ + REPLACE( (SELECT @str AS ‘*’ FOR XML PATH(”)) , @delim, N'</row><row>’ ) + N'</row></root>’); RETURN STUFF ( … Read more
For Sass versions 3.2 and older, these are all of the valid ways to use the parent selector: .foo { &, &.bar, &#bar, &:after, &[active] { color: red; } } .foo { .bar & { color: red; } } As of Sass 3.3, this is valid: .foo { &bar, &-bar { color: red; } } … Read more
This is because OSX and Linux use two different sets of tools. Linux uses the GNU version of the date command (hence, GNU/Linux). Remember that Linux is Linux and OS X is Unix. They’re different. You can install the GNU date command which is included in the “coreutils” package from MacPorts. It will be installed … Read more
In the Unix world, there were a few possible arrangements for the sizes of integers and pointers for 64-bit platforms. The two mostly widely used were ILP64 (actually, only a very few examples of this; Cray was one such) and LP64 (for almost everything else). The acronynms come from ‘int, long, pointers are 64-bit’ and … Read more
