Hello, My name is Sean Mikalson. I am a second year Software Engineering student with a combined degree in Philosophy. I am interested in participating with Xapian in GSOC this year and a couple of projects have initially caught my eye: - Dynamic Snippets - QueryParser Reimplementation I have good working knowledge in C/C++, Java and SQL (specifically Transact-SQL). In order to determine

Hi, For some maybe dumb reasons I try to write a portable version of int128. What is very valuable for this implementation is access to MUL instruction on x86 which provides full 64 x 64 -> 128 bit multiplication. An equally useful on ARM would be UMULH instruction. Well, the way you can access this on clang / GCC is to use __int128 type or use inline assembly. MSVC provides an intrinsic for

Hello, I have a script in R language that makes sorting using the order() method of R language. What I need is to reimplement this method in any other language (PHP, Perl, Python, Java maybe). First I tried to reimplement it in php, here is some numbers that i need to sort: 1,2,3,4,5,6,7,8,9,10,300,231,11,12,0,1 R language: n = c(1,2,3,4,5,6,7,8,9,10,300,231,11,12,0,1) n [1] 1 2 3 4 5

Hi All, I've gotten a number of reports from users about gplots::heatmap.2 generating 'node stack overflow' errors. As it turns out, these errors originate in stats:::plotNode, and are triggered when it is passed a dendrogram that is too deeply nested. While increasing the stack size (which is a compile-time option for byte coded functions) can allow a particular instance to

hello everyone, I am Maheshwar, a prefinal year Computer Science undergraduate student at BITS-Pilani, India. When i was going through the GSOC ideas , i felt interested in Quesry parser project. Till now i have implemented a couple of LL(1) parsers as a part of my assignment in Compiler construction course, so i would love to join and contribute to this project. So can any one tell me how to go

On trunk we never generate MULX. We used to blindly use it anytime bmi2 was enabled, but its a longer encoding and isn't a guaranteed register allocation improvement. So I took it out a few weeks ago. We need a more precise heuristic for when to use it. LLVM trunk will never generate ADCX/ADOX either. This was removed in September. We used to inconsistently generate them when adx was enabled

The function is applicable for MBR partitions only (as noted in documentation and as function name suggests).

I have prices that I am finding difficult to compare with ==, > and >, due to precision. For example: the numbers should match, with '==', but they differ in the magnitude of 1e-14 due to bunch of calculations that I run on them. Programming with java, I am used to implementing a function that compares the difference between the numbers to a pre determined precision factor. This
