48+ min ago   (136+ words) First problem: 404 doesn't mean "no results." Second problem: my retry budget wasn't big enough for a real outage. Third problem: a hung connection defeats retries entirely. Fourth problem, and the sneaky one: a field just disappeared from the response shape....

1+ hour, 21+ min ago   (935+ words) Read on: the test that never failed because it proved 1 = 1 · 繁體中文版 I had not deleted a single article, and yet 31 of them were completely gone from the site. Not in the series cards, not reachable through the category filters, not…...

1+ hour, 22+ min ago   (883+ words) A simple C library for plotting histograms in the terminal. Tagged with coding, github, opensource, programming....

1+ hour, 22+ min ago   (863+ words) I have been using Bun since it first started getting attention, but I had never used it as a production runtime. Mostly scripts, small tools, and things that run on my own machine. One reason it never went further is…...

1+ hour, 51+ min ago   (589+ words) A containment flag can be wired correctly, tested, documented, and still be a containment flag you do not have. The wiring is only half the story. The other half is where the baseline lives. Here is the whole audit, with…...

1+ day, 16+ hour ago   (761+ words) Vectorization replaces manual, element-by-element loops with operations that run across entire arrays at once. The speed gain comes from compiled code, CPU features like SIMD, and better memory access, not from shorter syntax alone. The technique has limits: dependent calculations,…...

2+ hour, 3+ min ago   (215+ words) C gets hard to trust in three predictable ways: deep nesting, pointers to pointers, and a->b->c chains where nobody null-checks the middle pointer. So I wrote a tiny scorer that squashes that into one number per function: Each factor is…...

2+ hour, 35+ min ago   (697+ words) Every SFTP file transfer in Termphin ran at exactly 1.2 MB/s. Not roughly 1.2 on average: the same figure on every server, over every network, for every file, large or small. A number that stable is not a network. Networks vary. A…...

2+ hour, 49+ min ago   (1133+ words) Remote help is not free if the hop is slow. A prompt that never leaves disk cannot leak. The cheap path is a local cache with a measured fill. Most coding assistants resend the same context twice. The second trip…...

2+ hour, 46+ min ago   (532+ words) A repository can contain a file under.apc/ without making that file part of the APC contract. The APC folder structure specification says consumers ignore unknown paths unless a formal APC extension defines them. That small rule gives teams room…...
