melissalobos··on Is GitHub Down?
Fine in ABQ
melissalobos··on Nasm – A cross-platform x86 assembler with an Intel-like syntax
I had to use a bit of assembly recently and chose nasm for it. A client had an older piece of compiled code and wanted to be able to use it on a modern machine. It was written in a propriety language and compiled for a 32bit system. The argument passing conventions used by the compiler were unusual. So I wrote a bit of assembly in nasm to create a stub function callable from C, it was really just moving things into the right registers and some bits to the stack. So nothing really being done in the asm. The hard part was figuring out the calling convention.

Edit: Looking back it turns out that "recently" was 18 months ago.

melissalobos··on An ad plugin was stealing revenue for a year and I didn't even notice
At least the plugin guy was reasonable-ish. That does sounds like a really odd experience. It does pay to always check all of the dependencies you are using and their terms. When I was younger I got hit by limits when using a free tier of a service, but they just throttled us which lost us users.
melissalobos··on How Claude Shannon helped kick-start machine learning
It actually is, most papers written today are cut and paste jobs with multiple people writing one section. The quality and focus from one paragraph to another can change. I think the lack of computers helped a bit as well for the quality of earlier papers. There used to be a lot of effort needed to publish a single paper since computers couldn't do typesetting.

Aside from that he has what comes off as a very clear mind. If you haven't I would highly recommend reading his papers. Coherent is a good adjective to describe his work.

melissalobos··on Zlib – a spiffy yet delicately unobtrusive compression library
I have tried using zlib-ng on a project before, but I found it had too many issues when trying to deploy it. Almost every distro packs zlib, and zlib is so fundamental you can't just wholesale replace it, so you wind up with an almost the same library and regular zlib. I can't remember the exact details(maybe something with RPATH?), but we had to wind up just using the system zlib due to deployment issues.
melissalobos··on Ask HN: What is the largest dataset you know of?
C4 uncleaned is ~ 2.3 TB (https://huggingface.co/datasets/c4) which is a huge amount of only text. Otherwise I have worked with a video hosting site that had more than 100's of TBs of data.

It occurs to me that there are several measures of biggest. Raw size, number of rows, etc. which did you mean?

melissalobos··on The Polygons of Éric's Chahi Another World
That was a very interesting article, I was surprised at how dense the byte code was. Seeing what people can do on platforms like that and DOS reminds me that we should always try to make things simpler.
melissalobos··on Ask HN: Is there an efficient way to monitor my identity
If you just want your credit report the official site is (https://www.annualcreditreport.com/) which looks fishy but is real (https://www.consumer.ftc.gov/articles/free-credit-reports). I am not aware of any more authoritative source or any API.

>Only one website — AnnualCreditReport.com — is authorized to fill orders for the free annual credit report you are entitled to under law.

melissalobos··on Ask HN: What do you use SQLite for?
I use it for a personal notes app, any Android app I have made. I don't think I have needed a serious DB like postgres for any project in the last 5 years, sqlite has been more than enough.

If I were at the same scale as Facebook or Google I would probably pick something with a better concurrency story though.

melissalobos··on Ask HN: What languages deploy and are also themselves standalone executables?
If your goal is just to produce a single file that is equivalent to a large number of files and a single executable, I would suggest you look at AppImage(https://appimage.org/) you can make almost anything into an AppImage from any language, although it is not always easy to setup(check out the packaging guide https://docs.appimage.org/packaging-guide/index.html).

> The key idea of the AppImage format is one app = one file

melissalobos··on Asimov, Programming and the Meta Ladder
I think more of the danger with Copilot is that managers will believe that it makes programming easy and so they will think programmers should be compensated less or they need less of them.
melissalobos··on Ketogenic Diets and Chronic Disease: Benefits vs. Risks
For resistant starch, you can look up the "Potato Hack" or other similar things for popular information. There have been a large number of articles you can find on Google Scholar about cooking potatoes/rice/other things and cooling them to produce RS(resistant starch).

melissalobos··on WebAssembly techniques to speed up matrix multiplication
That sounds very interesting, is the anywhere I can read more about this optimization? I didn't know any compiler could do optimizations like that.
melissalobos··on Google Drive flags file only containing “1” for copyright infringement
It may take some time for it to index and check the file, youtube for example takes ages to process video, I would imagine google drive is lower priority. Check back in a week or two and see if it changes.
melissalobos··on [dead]
I am a bit confused by the claims of theft of the calculus in this article. I also don't really follow any of the thoughts on how the Newton could not have used the calculus because he did not know about the real numbers, or how the Indian calculus was based on polynomials. If anyone could enlighten me more, I would be very glad.
melissalobos··on Ajax the Great
I was writing up some notes for a mentoring thing on AJAX as in Asynchronous JavaScript And XML, and got caught up reading about Ajax instead. I thought it was interesting, and the naming of the web technology has to be somewhat intentional.

Does anyone happen to know the history of the naming? Was it meant to be a bit of a joke?

melissalobos··on Exercise Is Good for You, Even If You Have a Mild Case of Covid
It seems like the article is saying that as long as it is a mild case, and you are already somewhat fit, it is better if you exercise. However, if you are over 50, or moderate to severely ill, then don't. Which seems to make sense and it pretty common advice among gym goers.

Usually the saying is something like, "If it is above the neck you are better off exercising, below the neck wait and rest." Where above / below the neck refers to chest congestion versus nasal/sinus congestion.

melissalobos··on Solve Puzzle to Join Waitlist
I have a feeling the idea is that the puzzle is an example of the game they are trying to have people sign up for. Seems like maybe advent of code but fantasy themed.
melissalobos··on The Unreasonable Effectiveness of Mathematics – R.W. Hamming
I always liked his book on Numerical Methods, and his idea about knowledge as compounding interest. The part of this essay I enjoy is the second explanation:

> 2. We select the kind of mathematics to use. Mathematics does not always work. When we found that scalars did not work for forces, we invented a new mathematics, vectors. And going further we have invented tensors. In a book I have recently written [10] conventional integers are used for labels, and real numbers are used for probabilities; but otherwise all the arithmetic and algebra that occurs in the book, and there is a lot of both, has the rule that

> 1 + 1 = 0.

> Thus my second explanation is that we select the mathematics to fit the situation, and it is simply not true that the same mathematics works every place.

melissalobos··on Eating the red soil of Rainbow Island
Interestingly they note:

> traditionally used as a dietary supplement for pregnant women and children.

It seems like there is some are a lot of these mud eating practices that are associated more often with women. I wonder if there is some connection there with iron deficiency or something(total guess, but I know from experience that women tend more often to be iron deficient).

melissalobos··on [dead]
This is just spam, it is a repost on the blog of a Verge article.

melissalobos··on Eating the red soil of Rainbow Island
It seems like in this case the addition of the dirt might add some iron to their diet.

> Mehravari confirms that gelak “contains several different iron chemicals. It is possible that for those who are iron-deficient, eating the sauce will help increase the required level of iron in the body.”

I remember reading another article years ago about scientists trying to give some people a "lucky" iron fish to add to their pots while cooking rice to add extra iron, since the cookware was no long iron based.

melissalobos··on Eating the red soil of Rainbow Island
That just seems very very strange to me, having never eaten dirt myself or known anyone who has.
melissalobos··on Eating the red soil of Rainbow Island
That was very interesting, in the Times article they note that they don't eat it to get any minerals or other nutrients, which was my first thought. Do you have any idea why they do it?
melissalobos··on RPG Paper Maker
At first I thought this would be about pencil and paper RPG games, but looking at the website it is an alternative to RPG Maker, that has characters with a vaguely papery look to them due to use sprites in a 3-Dish setting.

It is written in Qt and produces games that run in Electron. So reasonably multiplatform. It is free if you don't make money with it, it looks like.

It is nice to see a largish project like this that blends Qt and Electron.

melissalobos··on Sphinx C
I had a - - after the C originally, but I think it was eaten. This is an alternative C-- from the one currently trending on the front page. Started a few years before it, and mildly popular in Russia among language developers for a bit.
melissalobos··on Rust for Embedded C Programmers
I don't mind the syntax, the bigger issue for me is that a lot of necessary features have been locked into nightly forever, like inline asm. If the language can ever mature enough to have these features in stable I would use it in a heartbeat. Well, that and the usual issue with it having a severely limited back-end selection compared with gcc.

Currently it may be overloaded, I tried a few times and his head just keeps spinning for a long time without anything happening.

melissalobos··on Geometry from Another Universe
> everything was happening in lower dimensional manifolds curving through that space where “all the action was.”

I feel like this would have to be true in a very high dimensional space, since an infinite dimensional orange is all skin.

> systems obeyed solid state physics type laws: stars formed an outer lattice and planets in small lattices around stars.

This sounds really fun, could you try explaining a bit more about it?

Thanks for sharing.
