O Christmas Tree, O Christmas tree, How lovely is your floof!
Not only green in summer’s heat, But also winter’s snow and sleet.

As a developer, I just want to "run" JavaCard applets on a desktop machine (arm64), so of course I had to pick up the remains of jcardsim to try to add some GlobalPlatformPro UX onto it. Called it JCardEngine. Next: global platform support with oracle's sim passthrough. github.com/martinpaljak...

What does it take for 640k of RAM on a #pcjr with IBM sidecars? Five of them. One for extra power, and 4 128k RAM expansions.

Mainstream news covered the Jeffrey Epstein emails related to ppl like Trump. Today, I want to take a look at Epstein's correspondence with prominent atheist and physicist Lawrence Krauss, who asked the pedophile's advice on responding to accusations of sexual assault skepchick.org/2025/11/so-i...
So I’m in the Epstein Files

Just released cargo-nextest 0.9.113, with support for a long-requested feature that I realized I needed all of a sudden: debugger support! Run individual tests under gdb, lldb, WinDbg, or Visual Studio Code via CodeLLDB! This preserves all the environment setup done by nextest.
Terminal window showing cargo-nextest running a Rust test with rust-gdb debugger. The test 'test_argument_parsing' from cargo-nextest is being executed. GDB (GNU Debugger) version 15.0.50.20240403 starts up, displaying copyright information, GPL v3+ license notice, and configuration details for x86_64-linux-gnu. The debugger is reading symbols from the cargo_nextest binary in the target/debug/deps directory. The prompt shows '(gdb)' ready for debugging commands.
