This is my project for last week’s D hackathon:
This project aims to visualize the evolution of D’s reference implementation across a number of metrics over time. It does this by building D at all points in its GitHub history, then running a series of measurements on each version. Continue reading
I am delighted to announce that my fork of the Very Sleepy profiler, Very Sleepy CS, has been blessed as the official repository by Richard Mitton (Very Sleepy maintainer). As such, the Very Sleepy homepage has been updated to point to the GitHub repository and list the forked releases since Richard’s last release. You can also read Richard’s announcement on his blog.
I have already reverted the name change in the source code, though the currently-newest release (v0.90) is still labeled with the old name. The next release will call itself Very Sleepy again.
ae.utils.funopt is a std.getopt enhancer:
import std.stdio, ae.utils.funopt;
int run(bool verbose, string input, string output)
int main(string args)
catch (Exception e)
stderr.writeln("Error: ", e.msg);
Running program --verbose input.txt output.txt will cause run to be called with the appropriate arguments. Continue reading
Some projects eventually get split up into multiple source repositories for whatever reason. Sometimes, it is useful however to present the project as a single repository – it’s more difficult to examine a project’s development history when it is scattered among several repositories. Specifically, git bisect will not be very helpful if there is strong inter-dependency between the repositories, such as with the reference D programming language implementation. Or you may just not like the layout, which pushes you into using a complicated build process you may not want to use, which was the case for me with the new DerelictOrg repositories. Continue reading
When working from the command line, I pass compiler output through a small tool that matches output lines against regular expressions and prints them in various corresponding colors. Continue reading
I got fed up with waiting/pestering Richard Mitton (aka Kayamon / @grumpygiant) to integrate the Very Sleepy patches I’ve sent him last year or putting the code on a software forge, so I’m publishing my patches on GitHub myself.
Very Sleepy is a polling Windows profiler with a wxWidgets-based GUI. This is a fork of the latest released version at the time of writing (0.82).
There have been a few more forks of Very Sleepy (e.g. here and here), but these are based off older versions. It’s possible that their changes had already been merged into the official version.
Update: I’ve continued development of my fork, at the above-mentioned location. Check the GitHub project for the changelog, downloads, and more information.
Update 2: Very Sleepy CS is now Very Sleepy!
While trying to set up my home network, I was dismayed that there was no simple way to test the DHCP server. Snooping packets is limited to examining existing traffic.
DHCP test tools exist (DHCPing and dhquery), however both are outdated and don’t work with the latest versions of their requirements, and both won’t work on Windows.
I’ve written a simple DHCP “client” which can receive and decode broadcasted DHCP replies, as well as send out DHCP “discover” packets. The tool is cross-platform, and should work on Windows and major POSIX systems.
Source, Windows binaries.
SysInternals CacheSet has a limitation: it is unable to set a cache size larger than 4GB. This is due to the fact that it is a 32-bit application, and the respective API (NtSetSystemInformation) accepts new settings as a 32-bit byte count.
The solution: use the 64-bit API, which uses 64-bit integers. I’ve written a very simple 64-bit CacheSet-alike – just enter the desired cache size (in bytes). You can use the original CacheSet to check the new settings (just don’t hit “Apply”, or your settings might get clobbered).
A tool that makes it easy to check if TRIM works on your SSD.
I was looking for a way to programmatically print a SWF file. The stand-alone Flash player has an option to print a SWF, however there is no shell action registered for it.
After looking around a bit, I found that probably the easiest way is to use the ActionScript PrintJob API: Continue reading
