blobcode··on The Lightbulb Computer
I wonder if something like this would work for whole-room projection (i.e. not just a projector on a swivel): https://dl.acm.org/doi/fullHtml/10.1145/3531073.3531126
blobcode··on Competitive Programmer's Handbook (2018) [pdf]
Wrong!
blobcode··on Hugging Face is billing OpenAI $100M for hacking it
much better techcrunch article here: https://techcrunch.com/2026/07/26/hugging-face-ceo-calls-for... (that the above post is seemingly entirely based on).
blobcode··on Nobody knows what a used GPU cluster is worth
It’s mostly due to higher temps resulting in faster ion migration, which can cause a breakdown in the structure of transistors, as well as increased wear on the conductors (though this is rarely a dominating factor). Thermal cycling can also cause cracking, which is also a problem. Though there are lots of reason chips fail due to heat, from the wire bonds on pads getting too hot to increased leakage current at high temps.
blobcode··on How Doctors die. It’s not like the rest of us (2016)
ICU costs are quite high in general, often 3-4x a regular bed, and about 5k USD average in countries such as Canada and the UK.
blobcode··on A US military exercise to launch a satellite on short notice
Although not quite exact, here's spending data for 2024 (https://fiscaldata.treasury.gov/static-data/published-report...) - about 14% of tax dollars went to defence, 0.14*17000=2380.
blobcode··on Linux gaming is faster because Windows APIs are becoming Linux kernel features
this is something cool done by valorant - see https://www.riotgames.com/en/news/demolishing-wallhacks-valo...
blobcode··on Airbus is preparing two uncrewed combat aircraft
(1) Aircraft rarely fly in anything close to formation in combat - large gaps are the norm (1-10 miles), and one would think that increased distance is something that could be exploited by an unmanned platform (able to take more risk, etc.)

(2) Remains to be seen.

(3) Individual Patriot missiles are around that price point, with S300/S400 anywhere from 500k-2M depending on capability. One would think that cost-per-kill would be favorable considering the increased capability granted.

blobcode··on The Culture novels as a dystopia
Some of the stories could plausibly have SC involvement (the story of the same name is most likely) - but I don't think it's explicitly mentioned anywhere.
blobcode··on The Hat, the Spectre and SAT Solvers (2024)
I feel like SAT solvers and the like are getting a lot more attention on HN recently (for example https://news.ycombinator.com/item?id=44259476) - justifiably so! I think that they're a great tool that's often criminally underused in industry for a whole subset of problems.

blobcode··on The language brain matters more for programming than the math brain? (2020)
> the requirements for advanced math classes for every computer science major seem unnecessary

Computer science is much more than programming - and I think that most of the value derived is from being able to think about problems, which largely require the abstract type of thinking encouraged by more advanced math. Code is just a tool.

blobcode··on If it is worth keeping, save it in Markdown
Then use any of the plethora of alternative text formatting tools (TeX, for one).
blobcode··on Ask HN: Do the tarrifs impact software/SaaS? If so, how?
Only if the US has a change to sane leadership to go along with it
blobcode··on The number of CS grads who don't even know basic Git commands is astounding
This is one of those things that MIT’s missing semester course aims to help with (https://missing.csail.mit.edu/), and although computer science is different from software engineering, the reality is that most CS grads go into software engineering, and thus should try and learn these essential skills.
blobcode··on Survey of Rickrolling in Academic Literature [pdf]
A mildly interesting note that this paper was submitted as part of SIGBOVIK (http://www.sigbovik.org/), a collection of similarly funny papers.
blobcode··on Ask HN: Good sources of math exercises for ~10-17 y/o?
For a younger age group (13-15 maybe), George F. Simmons’ “Precalculus Mathematics in a Nutshell” (https://www.amazon.com/Precalculus-Mathematics-Nutshell-Geom...) is quite good though might require a bit of help to grasp. It features lots of exercises and a quite decent explanations for the age range.
blobcode··on Do we need to store all that telemetry?
> we can also add local storage of telemetry data in an efficient circular buffer. Typically, local storage is cheap and underutilized, allowing for “free” storage of a finite amount of historical data, that wraps automatically. Local storage provides the ability to “time travel” when a particular event is hit.

I think that this is a good idea when storage is concern for high-volume logs / production. Persisting the buffer when high error rates / unusual system behavior is observed would be a cool idea.

blobcode··on Show HN: Building a GPS receiver
A good, decently detailed look at signal processing required. I also like https://ciechanow.ski/gps/, which has some fantastic visuals to go along with this explanation.
blobcode··on Integral Calculator
I think the really neat piece of software behind this is maxima (https://maxima.sourceforge.io/), a rather influential computer algebra system of ancient lineage still in use today in more places than you might think.
blobcode··on Show HN: I made a tool to clean and convert any webpage to Markdown
This is one of those things that the ever-amazing pandoc (https://pandoc.org/) does very well, on top of supporting virtually every other document format.
blobcode··on Penrose – Create diagrams by typing notation in plain text
It looks like the CLI tool (@penrose/roger) just depends on a few npm packages with no browser engine and supports SVG export.
blobcode··on The 1988 shooting down of Flight 655 as a user interface disaster
To my knowledge, the F-14 never carried any anti-ship missile, especially on the early-model Iranian Tomcats, as the F-14 only received an air-to-ground upgrade package in the 90’s.
blobcode··on Ask HN: IP cameras that don't require an app or internet?
There are a good number of androids that can run without a battery as long as they are plugged in, though that varies by model and manufacturer.
blobcode··on Show HN: Mafs – React components for interactive math
It seems like all interaction + scrolling is broken on the SE for me, although rendering and animations play.
blobcode··on An update on the threat landscape
Although not the F-22, modern fighters such as the F-35 can cost 100's of billions of dollars in R&D[0] (~150 billion iirc, with ~1.3 trillion total program cost).
