Sunday, 3 May 2015. Review: UndoDB, a reversible debugger. This is a review of a reversible debugger. It's a debugger for Linux, with GDB compatibility, which means it is a drop-in replacement for debugger frontends on the Linux platform (e.g. Eclipse, DDD, and also the IDE I use at work. Which is GNAT Programming Studio. Like recent versions of GDB, it is able to "run" code backwards. Like features provided by IDEs, or the invaluable error-detection capabilities of Valgrind. I first saw a reversible deb...

On this page, you will find some games made by me for wife Jillian. The games are modifications of existing games. Nethack Valentine's Day 2004 Special. This game is based on Nethack. The classic dungeon adventuring game. Jill is a big fan of Nethack, indeed, she entered the Devnull Nethack Tournament. And ascended six times, and won a Hat Trick trophy. Nethack-3.4.3-vds-binary.tar.gz. A binary for Slackware Linux. Should work on most i386 Linux systems. Nethack-3.4.3-vds-patch.gz. The game source code.

The virtual lab provides a remote FPGA. The manual for the virtual lab. Is now online. Some of the software, such as client libraries, can be downloaded. The virtual lab uses the following software:. An embedded system based on Linux software. FPGA hardware. This acts as an interface between a TCP/IP network and an FPGA board, allowing the board to be programmed and controlled using a serial protocol. I modified the Linux kernel. For this device and wrote the embedded application.

Is an emulator for the Hitachi 64180. The CPU for the Single Board Computer used in the MCP course. Taught at the Department of Computer Science. It is an update of the em80 program used in CTS. It supports all of the 64180 instructions, and has some support for the 64180 serial port system (ASCI). It also has a few other features that make it a bit easier to work with than em80. em180. New features in em180. You can turn on ASCI emulation in em180. To activate this feature). And they will work properly.

Jack Whitham: April 2015
http://blog.jwhitham.org/2015_04_01_archive.html
Sunday, 26 April 2015. Relative speed of Raspberry Pi, Pi 2, and desktop PC (x86 and AMD64). Posts described my attempts to build a benchmark program from the Quake 2 source code, to complement a similar program I made. From the Doom source code. The main issues have been related to floating-point numbers; much of the effort has gone into discovering why the rendered output from Quake 2 was slightly different with different GCC configurations, different CPUs and different math libraries. Both benchmarks ...
Jack Whitham: More fun with floating-point numbers
http://blog.jwhitham.org/2015/04/more-fun-with-floating-point-numbers.html
Saturday, 18 April 2015. More fun with floating-point numbers. Last week's post on compiler optimisations and floating-point numbers got some interesting feedback, including various suggestions for hardware/software workarounds, and also some horror stories, which you may find here. The spot-the-difference puzzle was admittedly rather difficult. Here's an easier one:. In the transparent texture on the right-hand side of the frame. There is one correction. To last week's post. It is. And made something of...
Jack Whitham: GCC Bug 323 - a journey to the heart of floating-point darkness
http://blog.jwhitham.org/2015/04/gcc-bug-323-journey-to-heart-of.html
Sunday, 12 April 2015. GCC Bug 323 - a journey to the heart of floating-point darkness. What does the -O option for GCC do? Does it ever cause problems? Here is a "spot the difference" puzzle:. These are screenshots from a Quake 2 demo. They come from exactly the same point in the demo. They are nearly. The same. The one on the left comes from Quake 2 compiled in debug mode (no optimisation). The one on the right is from release mode (optimisations on). Where is the difference? I used that for testing FP...
Jack Whitham: October 2013

Sunday, 20 October 2013. If you are ripping a CD, and compressing the music for storage on your computer or portable player, what bitrate setting is enough? I am writing about " lossy compression. Software is used to process music files on a CD, removing parts of the sound that are (theoretically) inaudible, so that the music can be stored in less space. MP3, AAC and Ogg Vorbis are examples of lossy compression formats, and my portable player. Too high, and space is wasted, on the hard disk and on the po...
Jack Whitham: The mystery of the fifteen-millisecond breakpoint instruction
http://blog.jwhitham.org/2015/04/the-mystery-of-fifteen-millisecond.html
Sunday, 5 April 2015. The mystery of the fifteen-millisecond breakpoint instruction. How long does a breakpoint instruction. When reached, a breakpoint instruction stops program execution and sends a signal, e.g. "SIGTRAP" on Unix, which may be received by a debugger or by the program itself. As part of a small project, I was looking into efficient ways to invoke a signal handler within a program running on a Raspberry Pi. I wanted a method that required only one instruction. My experiment was carried ou...

You may also know that various intelligent and technical people have proposed solutions to deal with it: solutions that they invariably believe to be clever and novel.

My Ramblings
A random collection of thoughts, observations, contemplations, considerations, and other musings that fall out of my head. Sunday, October 9, 2016. Touching bits of history. This lodge is special to me. While I was not made a Mason in this building, three generations before me were: my father, grandfather, and great-grandfather. All passed on long before I became a Mason. I regret not starting my journey earlier, to enjoy that connection in person. Links to this post. Wednesday, May 13, 2015. First, in m...
