russfink··on US Government releases first batch of UAP documents and videos
In the same vein - the Roswell Museum and Research Center - the library portion is underrepresented in its ads. It is a library about the size of an elementary / middle school library filled with supposed accounts and testimony, academic-style papers and reports. One could spend days admiring this collection. (I’m not shilling for it, just pointing out the best part is not the latex cadavers in the other room.).

russfink··on Canvas is down as ShinyHunters threatens to leak schools’ data
It depends on what vintage of Blackboard your IT team has installed. We moved from a circa 2011 BB instance to Canvas in 2022, and it was hands down superior. A different university is running the most recent BB and it’s similar to Canvas.
russfink··on Claude Opus 4.7
LLM’s: sometimes wrong but never in doubt.

Or, the first time a mistake is detected, a correction is automatically applied.
russfink··on Turing Completeness of GNU find
Okay, but what are the cybersecurity implications of this discovery? A new living-off-the-land approach? Resource exhaustion? Covert servers?
russfink··on Turing Completeness of GNU find
Sorry for the novice question, but how do you determine this is AI?
russfink··on Official specification and reference code for Fast Lightweight Online Encryptio
Not sure I understand the problem this is trying to solve. I can hash a 2Gb file with an empty hash placeholder, sign the hash and store it in the file. Then on decryption, zero out the placeholder, hash the whole file, and compare the result to the included signed hash placeholder without storing 2Gb in memory.

russfink··on I started programming when I was 7. I'm 50 now and the thing I loved has changed
I must be the only one who thinks this, but this is the age of getting things done. I don’t have to worry about syntax or off by one errors, I tell it what to do and it generally does it, instantly!

Oh, and I’m 57 and was programming the Commodore Pet when I was 11. I’m relieved to be (mostly) free of syntactic shackles.

Vote me down, but also prove me wrong.

russfink··on How not to securely erase a NVME drive (2022)
sedutil-cli —yesIwantToEraseALLmydata $PSID /dev/sda1 or something like that.
russfink··on After two years of vibecoding, I'm back to writing by hand
This. Most people defer the solving of hard problems to when they write the code. This is wrong, and too late to be effective. In one way, using agents to write code forces the thinking to occur closer to the right level - not at the code level - but in another way, if the thinking isn’t done or done correctly, the agent can’t help.

russfink··on Scanning ultrasound as a neuromodulation therapy in Alzheimer's disease
> With four treatment sessions spaced fortnightly,

This is a clearer statement of “Every two weeks” than “bimonthly” or “semimonthly.”

Brilliant!

russfink··on The Accountability Trap: Why School Systems Abandon Gifted Students
Mathematically speaking, “no child left behind” is equivalent to “no child out in front.”
russfink··on Show HN: Ez FFmpeg – Video editing in plain English
Except what if you don’t really grok those ffmpeg flags and the LLM tells you something wrong - how will you know? Or more common, send you down a re-encode rabbit hole when you just needed a simple clipping off the end?
russfink··on I can't upgrade to Windows 11, now leave me alone
Ten years old laptop? Pretty sure it has a TPM 2.0 on it.
russfink··on Reflections on AI at the End of 2025
Practical question: when getting the AI to teach you something, eg how attention can be focused in LLMs, how do you know it’s teaching you correct theory? Can I use a metric of internal consistency, repeatedly querying it and other models with a summary of my understanding? What do you all do?
russfink··on MIT Missing Semester 2026
Conspicuously missing is a direct mention of AI tools. Is MIT, like others, side-stepping the use of AI by students to (help them) complete homework assignments and projects?
russfink··on MIT Missing Semester 2026
Link to the About page that clearly describes the effort and rationale.

russfink··on Workday project at Washington University hits $266M
Back in the day, wustl.edu was seen as a leader in computer applications. Sad now that it cannot just create its own systems to handle its tasks, especially with AI’s around to offer coding help. Imagine spending a fraction of this money and vectoring it to students to develop said systems.
russfink··on If you're going to vibe code, why not do it in C?
One trick I have tried is asking the LLM to output a specification of the thing we are in the middle of building. A commenter above said humans struggle with writing good requirements - LLMs have trouble following good requirements - ALL of them - often forgetting important things while scrambling to address your latest concern.

Getting it to output a spec lets me correct the spec, reload the browser tab to speed things up, or move to a different AI.

russfink··on After nearly 30 years, Crucial will stop selling RAM to consumers
Damn … Crucial P3 plus and P5 plus support Opal 2.0 full disk encryption. This leaves Samsung standing nearly alone in the consumer market, except for some smaller names.
russfink··on Xlibre is a fork of the Xorg Xserver with lots of code cleanups
If it matters, many of their issues were apparently closed without comment. Here is an issue asking to resolve this. It also lists many of the commits.

russfink··on Garfield's proof of the Pythagorean Theorem
May be a repeat here, but best proof I saw was inscribe a square with sides of length c inside another square, but rotated such that the interior square’s corners intersect the outer square’s edges. The intersecting points divide the outer square’s edge making lengths a and b.

This produces an inner square’s edge with sides length c and four equal right triangles of sides a, b, and c.

Note that the area of the outer square equals the sum of the inner square plus the area of the four triangles. Solve this equality.

russfink··on Anti-patterns while working with LLMs
“Build me a fishing pole” instead of “catch me a fish” is the best advice this article has (sans my fishing metaphor).
russfink··on Microsoft's lack of quality control is out of control
Try the Developers remix. Total ear worm.

russfink··on Recursive macros in C, demystified (once the ugly crying stops)
Is this a DoS risk - code that sends your build chain into an infinite loop?
russfink··on Chaining FFmpeg with a Browser Agent
I use LLMs to help navigate FFmpeg. It hasn’t failed me yet.
russfink··on How to Read a Paper [pdf]
Nowadays, do pass 1 (abstract, intro, headings, conclusions), upload the paper to your LLM, then ask questions interactively. LLMs can make step 3 a lot more efficient.
russfink··on The security paradox of local LLMs
I get the impression that somehow an attacker is able to inject this prompt (maybe in front of the actual coder’s prompt) in such a way to produce actual production code. I’m waiting to hear how this can happen - cross site attacks on the developer’s browser?
