The logos were very popular on twitter, see the account of the author here:

The open issues almost all requests for different logos.

People have already made their own t-shirts, stickers, keychains etc. using the logos:

That's quite incredible. The power of having a such a large social media following I guess.


The larger follower count comes FROM this project. I've seen a lot of people being really excited for this style and hoping their own tech stack comes next.

It's just something cute to celebrate tech.


> I've seen a lot of people being really excited for this style

I don't know what's the name of that style, but it's used a lot in the vtuber community. So much so that searching "vtuber logo" on Google Images will return mostly images that look very similar to those from the repo.


Right, I can see they had < 2000 followers before this project, now 14.5k.

This already happening in many places. And does not seem to be he intended application in the OP


At least for science books, authors get paid very little or nothing. And no researcher/teacher relies on that for their income.


That actually makes it worse, not better. You’re basically denying authors the peanuts they get.


Look up the incredible profit margins of publishers such as Elsevier or Springer.

University researchers/teachers who publish books or articles through them often get paid nothing (zero), or very little. And they do not care, since their goal is get publications in prestigious venues, which helps them in their academic career.

My point is that this stuff should be free, open access, published at low cost through university presses etc. So pirating academic books is basically fine.

That should be up to the author, no? If they decide to not make it open source and take a tiny profit, that's their decision since it's their work.


Well they can publish it on LeanPub and charge 20$ instead of 200$(of which most goes to publisher). Some books are just predatory business.


Sure, but publishers do a lot of promotion, have upfront bonuses, guaranteed quantities. There is a reason why people go with publishers and don't self-publish. You're paying for the reach and marketing.


I suppose most people using LaTeX come from a scientific background. If you write math papers (for example) there is no good alternative to LaTeX. It has many issues but mostly it just works, so people are content with it.

If you want to write a novel something like Word is probably better. Or just use a typewriter if that's what you like.


This is the typical knee-jerk reply I have come to expect from LaTeX users.

Word actually had a kinda good equation editor 30 years ago, and there are numerous WYSIWYG equation editors, including ones which output to LaTeX. For more technical applications JAX does a good job. I'm not suggesting you should stop liking LaTeX, but the claim that 'there are no good alternatives' is just a pompous way of saying you prefer it to other options.


I thought the question is not why this is a problem, but rather why is it possible at all for a loose object to end up in the depths of the AC to cause problems. Is there some reason we cannot avoid this?

From a laymans perspective I think of a car, where dropping something small while driving is unlikely to cause problems in the machinery.


Cars have a lot of trim/seals/insulation/carpeting to reduce road noise and be aesthetically pleasing, and military aircraft cockpits don't care about either of those things, and are largely just a metal tube with racks on which all of the avionics and other cockpit equipment are mounted, with holes in a handful of places where wiring harnesses enter/exit the cockpit. All of that equipment is regularly worked on, removed/replaced, and so it is necessary that it be (relatively) easy to access and remove.

The equivalent would be like if you had to pull all of the instruments, electronics, and seats out of your car every 1000 miles, clean them up, replace faulty bits, and then put it all back again. All of the fancy trim, carpeting, etc., just makes that job harder, so you would probably want a car that doesn't have any of that, and is designed to make doing that kind of work easier, better still if you can avoid having to remove everything, and only have to remove the bits individually that need to be maintained. The down side of course, is that without all of the fancy trim and stuff, there would be gaps where things could fall and be hard to reach, and holes where wiring travels to the engine compartment/trunk/etc. Of course, FOD presents way less of a danger in a car than it does an aircraft, so you might not care if you drop something there, but aside from that, I think the analogy holds up.


Depending on your definition of “small” this is not true. I used to slide my flip flops off while driving until one got wedged under the break pedal and prevented me from breaking.


Well, for starters, cars are designed to only travel in two dimensions, so that limits the problem quite a bit.


I think it is impressive he figured this out as a layman. This article is from one year ago, it would be interesting to see a response from some researchers. For example, have there been any studies to see if this method is valid?


Hmm seems he is a retired researcher, although it doesn't mention his background. The problem is it's quite a step up from anecdotal evidence from one guy, to doing any kind of trial involving volunteers, and it would need momentum and money behind it.

It does seem there is some evidence already on breath re-training / diaphragm strengthening: https://www.europeanreview.org/wp/wp-content/uploads/4547-45...


I don't think this is accurate. For example square root of -1 was motivated by clear applications in mathematics, it was definitely not just idle leisurely math. Most of important pure math has not been leisurely or recreational in any sense in its origin


Before the 19th and 20th century, much of the basis of modern math was entirely leisurely and recreational. Even today that still rings true. I recommend reading Barry Mazur's "Number Theory as Gadfly" to add some context to that claim.


> And -let me get this right- you want society to keep paying you, so you can play with your imagination?

No, pure mathematics is almost never completely recreational. No serious paper gets published in a decent journal without having some motivation and connection to the rest of mathematics.

It is of course valid to ask why we should fund research in pure mathematics, which is not directly related to any "real" applications.

Same question applies to things like niche art, literary studies, history, etc. One answer is that these things are relatively cheap, and our culture would be poor without these things.

With pure maths the advantage is also that it is cheap, and the payoff in applications (if and when they happen) is high.


Note well that the article makes a strong point that any practical benefits of mathematics are, essentially, a side-effect, and even a distraction:

It would be bad enough if the culture were merely ignorant of mathematics, but what is far worse is that people actually think they do know what math is about— and are apparently under the gross misconception that mathematics is somehow useful to society! This is already a huge difference between mathematics and the other arts. Mathematics is viewed by the culture as some sort of tool for science and technology. Everyone knows that poetry and music are for pure enjoyment and for uplifting and ennobling the human spirit (hence their virtual elimination from the public school curriculum) but no, math is important.

Also see the first two stanzas of the dialogue between "SIMPLICIO" and "SALVIATI" that follow the above paragraph. I think, in other words, that the author would say that the "motivation" in pure mathematics papers is more of a pretext to be able to get published and continue one's work unobstructed, than something that the mathematicians themselves really care about.


Many people have been inspired by this book and it is entertaining. But in terms of history it is notoriously inaccurate, and some parts are just made up to make it more exciting.


> you should not, absolutely not translate math notation to code.

I don't see a problem, if eg it helps with getting some intuition.

Sure there is a formula for this example. But the point in the article of writing this sum as a for loop is to explain what the notation means.

For a programmer who is not familiar with sigma/pi notation for sum/product, explaining it with a for loop is a quick way to understand.


Exactly, that was my take-away. You don't need to think of the Sum function as a for-loop every time you use Sum, but it certainly helps explain it to a programmer who doesn't have a sense of what Sum is, but knows what a for-loop is.
