• How do I debug an MPI program?

  - by Jay Conrod

  I have an MPI program which compiles and runs, but I would like to step through it to make sure nothing bizarre is happening. Ideally, I would like a simple way to attach GDB to any particular process, but I'm not really sure whether that's possible or how to do it. An alternative would be having each process write debug output to a separate log file, but this doesn't really give the same freedom as a debugger. Are there better approaches? How do you debug MPI programs?

• libevent buffered events and half-closed sockets

  - by Vi

  It is simple to implement a port mapper using bufferevent_* functions of libevent. However, the documentation states that "This file descriptor is not allowed to be a pipe(2)". Will libevent work correctly if I shutdown the socket in one direction shutdown(socket, SHUT_WR);? I expect it to discard remaining data in the buffer and not write there anymore, but continue reading from socket and calling a read handler.

• Why do ASP.NET applications appear to be running in a terminal server session?

  - by Heinzi

  Running the following ASPX page (IIS 6, Server 2003 R2) <%@ Page Language="vb" AutoEventWireup="false" %> <% Response.Write("Am I running in a terminal server session: " & _ System.Windows.Forms.SystemInformation.TerminalServerSession) %> yields the following output: Am I running in a terminal server session: True Why? IIS is running as a service, not as a Terminal Services application... (BTW, according to Reflector, SystemInformation.TerminalServerSession is just a wrapper for GetSystemMetrics(SM_REMOTESESSION).)

• Writing preprocessor directives to get string

  Can you write preprocessor directives to return you a std::string or char*? For example: In case of integers: #define square(x) (x*x) int main() { int x = square(5); } I'm looking to do the same but with strings like a switch-case pattern. if pass 1 it should return "One" and 2 for "Two" so on..

• Regex one-to-one mapping pattern replace

  - by polygenelubricants

  How would you use regex to write a function that replaces all lowercase letters with uppercase and vice versa? Note: this is NOT a homework question. See also my previous explorations of regex: Regex split into overlapping strings (Alan Moore's answer is especially instructive) Can you use zero-width matching regex in String split? (my solution exploits a known Java regex bug with regards to non-obvious length lookbehind!)

• What do you think about ??= operator in C#?

  - by TN

  Do you think that C# will support something like ??= operator? Instead of this: if (list == null) list = new List<int>(); It might be possible to write: list ??= new List<int>(); Now, I could use (but it seems to me not well readable): list = list ?? new List<int>();

• Using Server.CreateObject("ADODB.Stream") in IE7

  - by Daud

  I have a asp.net 1.1 application that uses the following code to write out a file in the response: Dim objStream As Object objStream = Server.CreateObject("ADODB.Stream") objStream.open() objStream.type = 1 objStream.loadfromfile(localfile) Response.BinaryWrite(objStream.read) This code is called by a pop up window that displays this file or gives a open/save dialog in Internet explorer. The problem is, that it seems to work fine in IE6 but in IE7 the pop up opens and then closes without displaying the file. Any one know whats wrong?

  - by Weadadada Awda

  • the hash function: h(x) = | 2x + 5 | mod M • a bucket array of capacity N • a set of objects with keys: 12, 44, 13, 88, 23, 94, 11, 39, 20, 16, 5 (to input from left to right) 4.a [5 pts] Write the hash table where M=N=11 and collisions are handled using linear probing.

• Java: Moving Away from XML Encode

  - by bguiz

  Hi, We have this software which loads various bits of data from files that are written using XMLEncode (serialization using XML). We want to migrate from that to our own proprietary file format (can be XML based). Is there a automated way to achieve this initial conversion, without having to perform a deserialization, and then write those objects out in the new format? XMLEncode format --> New proprietary file format Thanks!

• Django site on Nginx+FastCGI goes (504 gateway timeout)

  Sometimes my whole Django based site goes into 504 gateway timeout errors so none page can be displayed. Is it possible to write a shell program and cronjob it run every 5 minutes to detect such errors and restart FastCGI process if needed? I'm currently using command below to restart FastCGI in case it's crashed but it doesn't work for above situation because when 504 gateway errors occur, the processes are still running. ps ax | grep -v grep | grep port=8001 > /dev/null || restart_fcgi.sh
