Loren_SL··on Who is cleaning up all the garbage LLMs generate?
Have agents write scratch output outside the repo, while anything that matters lives in version control. That way you can purge the scratch files whenever you like.
Loren_SL··on Ask HN: How to Learn Systems Programming
Think of a project that helps you understand the machine and make it. Like visualizing virtual address space of a process. Input and output don't need to be fancy - just make a console application which read/writes using stdio.
Loren_SL··on Show HN: I built a post-mortem debugger for native Windows x64/x86 crashes
It is not every day you see a VMS reference! Interesting read.
Loren_SL··on Show HN: I built a post-mortem debugger for native Windows x64/x86 crashes
Thanks - I'll try to make it easier to read and tell what is going on.
Loren_SL··on Show HN: I built a post-mortem debugger for native Windows x64/x86 crashes
Good points - maybe "arcane" would have been a better word to describe WinDbg - you can do just about anything, provided you know the right incantation. I hope you enjoy ForensicDbg!
Loren_SL··on When the Debugger Lies
Nice writeup. WinDbg has the same stale-cache trap on live Windows targets.
Loren_SL··on Show HN: MCPJam - the first testing & evaluations platform for MCP servers
Does this work with stdio MCP servers? Or just http/https ones?
Loren_SL··on How do traffic signals work? (2019)
I always thought that traffic signals should be trying to minimize squared anger, where anger increases linearly with time spent waiting at intersection.
Loren_SL··on A freezable game clock to make my web based, tactics-RPG engine testable
Having a clock you can play with also opens up ability to do things like bullet-time.
Loren_SL··on Ask HN: How do you prevent sensitive data from leaking through debugging tools?
1: Don't keep it in memory. If you have to, keep it in memory for as short as time as possible and scrub it afterwards. For example, password fields.

2: If you generate crash dumps, scrub the dumps when you generate them. Some crash reporting services offer to do this automatically.

3: If you are writing anything client/server, where you control the server and the client runs on a users machine, never trust the client. Expect that it has been hacked, is being debugged, and is actively hostile.

Loren_SL··on Microcode in Intel's 8087 floating-point chip: the scale instruction
I remember getting a 80387 chip for my Compaq 386/20. It has the same size package as the CPU! Now that makes a bit more sense.
Loren_SL··on Porting the RAD Debugger to macOS
This is a great writeup — bookmarking it. ForensicDbg is Windows-only right now, but I could easily see a day where I'm in your exact shoes trying to get a native postmortem debugger running on macOS.
Loren_SL··on Muse – Meta’s personal AI agent
This sounds like you would be entrusting Muse with an uncomfortable amount of personal information.
