melissalobos··on Ask HN: Who is hiring? (August 2022)
Not to be rude or anything, but working in the ABQ area as well we have hired a few people who applied to Stellar Science, they have said they were just asked to submit a sample of work and never heard anything back. One or two of them my have been a bit bitter over it since they worked hard on their submissions. What exactly are you guys looking for or have your hiring standards changed or what usually leads to candidates not being hired.

This may sound like I applied and was burned, but I can assure you this wasn't the case, it just came up twice recently and a lot of people had gripes.

My comment as may be noted was more a commentary on the historical licensing of MINIX which lead to Linux, see the original post.

> What I wonder is why some of them chose not to publish their works when their hunches were correct?

What have you published? Or have most people?

melissalobos··on The Elusive Origin of Zero
Not sure, but maybe because it isn't a positional zero.
melissalobos··on Xv6, a simple Unix-like teaching operating system
I don't know quite what you mean? MINIX isn't free, which is pretty big for a student project. In fact people may have started a similar project(not big like GNU) to due to its price.

melissalobos··on Is JPEG 2000 a preservation risk? (2013)
Sure those were encountered there, but at least in my experience those are easily avoided. I have had to make test suites for this, and in my experience if you use reasonable libraries things work well.
melissalobos··on JavaScript Obfuscation Techniques by Example
To answer your question, yes. Someone absolutely can decode that and figure out the odds. If they couldn't then there would be less obfuscation used. A browser ABSOLUTELY has to be able to run the javascript. Anyone dedicated enough can de-compile that javascript to a program. Is it easy? No, but people do it all the time.

I have had to deal with client that thought they could keep some bit of code secret on a browser before. I have had to explain many many times that anything the browser can do a human can do. So if a browser can run the code, at some point a human can too.

melissalobos··on Is JPEG 2000 a preservation risk? (2013)
Why was it a huge mistake? There are decent libraries that support it. Did it just not work with your cloud setup or OS libraries?
melissalobos··on The case for bad coffee (2015)
"seek and ye shall find"? I mean they didn't exactly try to find out why they were drinking so much coffee, they were more trying to save money(I think).
melissalobos··on Arcan Display Server 0.6.2 – It’s all connected
I don't mean to diminish the post or the author, but I spent a decent amount of time reading through the pages and am about to try their code, but I get the feeling the author is a little either crazy or out of touch with how to communicate with people. It is clear they have made something interesting, but I can't help but feel there is something off in the communication of it.
melissalobos··on Rowan Atkinson: Visual Comedy (1992) [video]
Each series takes place in a different time frame and with entirely different characters so they each stand on their own. Anyone can watch the episode named "Beer" in the second series and find it funny for a 30 minute show.
melissalobos··on The Preprocessor Iceberg Meme
Right, but now you can't use that COUNTER value in a macro and have it stay the same value. Think about concatenating a variable name with the counter and trying to use that same new name later in the same macro. Like NAME ## __COUNTER = NAME ## __COUNTER -1; This won't work without some extra state.
melissalobos··on Torus-Earth (2014)
You can say exactly the same thing for a sphere. Really a sphere is just the skin, but in practice people will use phrases like "within the sphere" etc.. So it really doesn't matter, when it does people refer to the "boundary" of it or will just write some equations.
melissalobos··on Desktop Environments Resource Usage Comparison
> I realize that's a gross oversimplification

In part especially since KDE deliberately breaks up their core libraries into multiple sub-libraries(https://develop.kde.org/products/frameworks/), in order to make them available for reuse by other Qt projects. Which is not the case for XFCE. KDE also depends on Qt which is similarly broken up into smaller packages(e.g. https://packages.debian.org/buster/libqt5gui5 is depended on by https://packages.debian.org/buster/libkf5auth5). Even though the actual attack surface in terms of exposed functionality is similar.

melissalobos··on Desktop Environments Resource Usage Comparison
A lot of these types of comparisons done with distribution provided packages aren't really ever comparing what they think they are. KDE has a TON of components which can be optionally compiled/installed(like baloo or the PIM), which are not essential and offer features far beyond what a regular XFCE install will provide(and which most non-corporate users don't want). In addition there are lots of different flags and ways to compile each of these environments(and their related libraries) that can make all of them much leaner if that is the goal.

A fairer comparison would be to look at the most minimal install with similar compilation flags, or look at only what applications it would take to achieve some goal and compile and install only those parts needed to perform it using the desktop environment's applications.

melissalobos··on Rust Editors to Replace TextMate 2 – The Agony of Despair
> you'll get smooth 60 FPS at no extra CPU cost.

The key part there is no EXTRA cost. Most immediate mode GUI libraries redraw 60 frames everytime, so there is a constant somewhat high cost, especially compared with a retained mode program.

melissalobos··on Duktape is an embeddable JavaScript engine
> For some reason I remember the compiled size for Duktape being smaller

For any C library this is HEAVILY dependent on the compiler, compilation, and linking options used.

melissalobos··on Newer, better sunscreens have not been approved by the FDA
Sure and I was positing why they may have increased.
melissalobos··on Newer, better sunscreens have not been approved by the FDA
> People also dress differently in the sun than they did in the past.

Temperatures in those sunny areas have increased as well on average over the last few decades.

melissalobos··on Why I still recommend Julia
I do think that Julia in general isn't the best for interacting with C(based off of some experimenting 2 years ago). I have tried using it with a decent number of odd C libraries used in Scientific Computing(with actual capital S and C. Which always involved binary blob libraries.). I think if you control more of the stack it is a better language. But when using it with vendor provided binaries I ran into many many issues.

> "with actual capital S and C." This part was referencing the industry and not me being egotistic.

melissalobos··on Why I still recommend Julia
> niche programming language

I mean `niche` is a little weird here since Julia is very specifically a general purpose programming language. It just happens to be really really good at math.

melissalobos··on What it feels like when Rust saves your bacon
> High quality teams like the Linux kernel team

Which very notably does NOT use C++.

melissalobos··on Cross-compiling binaries for Windows is easier than building natively
> Including glibc?

Any reasonable person doing this would use Musl of course.

melissalobos··on Let's learn D game programming development (2021) [video]
> when you say community support is lacking, what do you mean?

I look up how to do X, find very few resources, more than half mention D1. Compare that with looking up X in Rust or Python, how many mention Python 2 or Rust before the editions.

melissalobos··on Diving into GCC Internals
It is true that that is of course faster. However, clang and GCC, both do release memory since with modern C++ software projects, it can take huge amounts of ram to compile them.

melissalobos··on Commercial-Emacs
I don't really understand what exactly this is. It looks like an open source version of emacs, but I don't understand how it is commercial. Could someone explain more or point to a better description of the project?
melissalobos··on What every programmer should know about solid-state drives (2014)
> A reputation for drives that fail faster than their competitors

How can they get that if they stuff enough fake reviews, plus the legion of consumers who would have no idea that the drive was the issue and not "viruses".

melissalobos··on A History of Punctuation
> For Mandarin, detecting the word boundaries in the absence of white space between word-indicating characters or character sequences has been a dedicated sub-task of NLP pre-processing

This is also really hard(at least for me) for second language learners.

melissalobos··on Modern programming languages require generics
> most people that whine about generics & performance don't know a lot about performance

Really it is almost everyone who doesn't know a lot about performance. Any modern programming language is targeted not at an expert, but a beginner(look at Rust which is supposed to be relatively difficult, yet is quite quick for people to pick up in my experience).

Languages should be able to be performant, even when used in poor ways. No matter what, people won't presort their data, since it likely comes from some database or csv file or json response or who knows what. So a language should be trying to accommodate that use case.
