Multiple ajax calls
This is slightly OT for which I apologise in advance, but I was wondering if anyone here has had any problems when making multiple ajax calls at the same time. I''m working on a large Intranet application which makes heavy use of ajax calls and the bugs are flying in from the testers that if they repeatedly click on a link that makes an ajax call then Internet Explorer can fall

Loop vectorization with the loop containing bitcast
Hi , The following loop fails to be vectorized since the load c[i] is casted as i64 and the store c[i] is double. The loop access analysis gives up since they are in different types. Since these two memory operations are in the same size, I believe the loop access analysis should return forward dependence and thus the loop can be vectorized. Any comments? Thanks, Jin #define N 1000 double

What to do with HUGE instance variables in Rails?
I''m learning rails and I can succesfully use the following things in the controller: @var1 = Var.find :all @var2 = Var2.find :all Problem is that the DB has about 260,000 lines which considerably slows everything down if I load everything in @var1. Isn''t there a way to load those items progressively? I treat them separately (e.g. no interactions between them) in the program so

Kerberos stopped working
Hi everyone, I am in a real panic here and would appreciate any help. I have students not being able to save any files! I have a samba server that was joined to a win2k active directory and running for months. I dont know why, but now it isn't working correctly. This error is filling my logs: ------------------- libads/kerberos_verify.c:ads_keytab_verify_ticket(113)

[LLVMdev] Loop Vectorization and Store-Load Forwarding issue
I have been looking into this small test case (Part A) where loop vectorization is disabled due to possible store-load forwarding conflict (Part B). As you can see, due to the presence of dependence distance 2 the loop is vectorizable only for a width of 2. However, the presence of dependence distance 15 (due to y[j-15]) results in store-load forwarding issue as store packet of y[16:17] (iteration

Running two win programs with Wine
Hello everyone, we have a windows program, called Assist that needs Acrobat Reader to run completely since it is basically a PDF viewer. This programs has plugins for Acrobat. I can run successfully Assist & Acrobat reader separately but Assist cannot run Acrobat by itself, I get a message that Acrobat is not running. Is it possible to do this with wine ?

network printers
Hi, I've configured Samba as PDC. It is to serve Windows 98/2000/XP workstations. Firstly everything works fine but with adding new users to the domain there occurs serious trouble. The network printers begin to refuse access. And then I noticed that the workstations begin to refuse access too. smb.conf --- [global] netbios name = OBLR workgroup = X125 server
