Left 4 Dead 2 Dropping Audio Bug/Issue
So I've been an avid user of Left 4 Dead 1 and 2. This problem only seems to arise in L4D2, where the audio will cut out. Now, not completely, some things will drop but some stay, for instance, I can hear the noise my gun makes, the shots fired but I don't hear characters talking anymore or any special infected sounds. Another instance is I'll see my gun firing but I'll hear the

How to implement tag clouds using plugin?
The code on http://blog.craz8.com/articles/2005/10/28/acts_as_taggable-is-a-cool-piece-of-code is based on the acts_as_taggable gem,anybody has done that using the acts_as_taggable plugin?thanks! btw:the code above uses the tag_count method,which is defined in the gem: def tags_count(options = {}) options = {:order => ''count

[nbdkit PATCH v2 0/2] Bounce buffer cleanups
Based on Rich's review of my v1 that touched only cache.c, I have now tried to bring all three filters with alignment rounding in line with one another. There is definitely room for future improvements once we teach nbdkit to let filters and plugins advertise block sizes, but I'm hoping to get NBD_CMD_CACHE implemented first.

RFC: Synthetic function entry counts
Functions in LLVM IR have a function_entry_count metadata that is attached in PGO compilation. By using the entry count together with the block frequency info, the compiler computes the profile count of call instructions based on which the hotness/coldness of callsites can be determined. Experiments have shown that using a higher threshold for hot callsites results in improved runtime

Question on induction variable simplification pass
Hi all, It looks like the induction variable simplification pass prefers doing a zero-extension to compute the wider trip count of loops when extending the IV. This can sometimes result in loss of information making ScalarEvolution's analysis conservative which can lead to missed performance opportunities. For example, consider this loopnest- int i, j; for(i=0; i< 40; i++) for(j=0;

Serial ATA Errors
Hello Everyone, I started seeing some ata errors on a server running FreeBSD 5.4-STABLE that I''ve never seen before. This probably has something to do with it but we just upgraded the RAM on the server from 1 GB to 2 GB (DDR 400), perhaps a cable got slightly loose. I''m pretty certain the hard drives are good since the server ran fine prior to the memory upgrade. What do the

[nbdkit PATCH v2 2/2] cache, cow: Reduce use of bounce-buffer
Although the time spent in memcpy/memset probably pales in comparison to time spent in socket I/O, it's still worth worth reducing the number of times we have to utilize a bounce buffer when we already have aligned data. Note that blocksize, cache, and cow all do block fragmentation and bounce-buffer alignment; this brings the logic in cache and cow (which were copied from one

[LLVMdev] Path forward on profile guided inlining?
I would like to start prototyping changes towards profile guided inlining. Before doing so, I wanted to get feedback from the community on the appropriate approach. I'm going to layout a strawman proposal, but I'm open to other ideas on how to approach the problem. Depending on what approach we settle on, I *may* be able to commit resources to actually implement this in the near

[LLVMdev] [RFC] Less memory and greater maintainability for debug info IR
...s. Here's some visibility into where my numbers come from. I got the 15.3GB from a profile of memory usage vs. time. Peak usage comes late in the process, around when DIEs are being dealt with. Metadata node counts stabilize much earlier in the process. The rest of the numbers are based on counting `MDNodes` and their respective `MDNodeOperands`, and multiplying by the cost of their operands. Here's a dump from around the peak metadata node count: LineTables = 7500000[30000000], InlinedLineTables = 6756182, Directives = 7611669[42389128], Arrays = 570609[577447], Others = 1176556[51...

RFC: Hotness thresholds in profile header
Hi, The problem we're trying to address: PGO transforms that are based on block counts need some way to answer isHotBlock() query. A simple comparison of the form block_count > N, for some constant N is not useful since even for the same program different profile inputs can cause different answers for isHotBlock() on the same block. This can be addressed by comparing against a reference
