> at a fraction of the cost We'll see about that, long term. The billions and trillions being wasted right now to get the foot in the door need to be earned back somehow at some po…

I am a research mathematician. In my field (abstract algebra, computational group theory), a sum or some such notation is like the most trivial of trivial things in terms of notati…

This is almost funny to me, because in many jurisdictions, software companies sure invested a lot of effort into painting people copying software as thieves . In Germany, they (the…

Not sure what you are talking about (is this sarcasm?), but on iOS, Safari allows you to add any website as an item to your home screen. I am pretty sure Android has a similar feat…

If the numbers were all that is wrong, that'd be OK. But it fails to list all data -- so the only way to navigate to the missing PRs is to know their number, and manually inserting…

GitHub stability has been bad for me. And recently even the data they show me in the web has been unreliably. Since yesterday, me and several colleagues noticed that the pull reque…

which is also driving me nuts because it frequently fails to update the issue and PR counts when I close issues or PRs. Only a hard reload, or closing the tab and opening a new new…

I find it strange to compare "math" with one programming language. Mathematics is a huge and diverse field, with many subcommunities and hence also differing notation. Your rant wo…

For me one is that one can write `for i = 1:3` is one when `=` means assignment otherwise (at least `for i in 1:3` is available.

And sometimes one man's terrorist is another's freedom fighter.... (Not to defend terrorism, but it's just not that simple)

Actually in math parlance, the map G \to GL(V) is the representation while V is the underlying module , and yeah its elements are vectors.

No you literally can (and the attackers did) change version 44 (the tag for it) to point to a different compromised commmit

> Nobody bothers explaining why the primes are spaced like they are I take it that means you also haven't taken (m)any number theory classes then ;-). Because people wildly care ab…

Which robber baron do you consider to be responsible for curing polio?

Marc Zuckerberg being popular is not the same as his platform being popular.

I am a professor for algebra at a research university. I make a point out of teaching my students that `a/b` is NOT the same as multiplying `a` by the multiplicative inverse of `b`…

Wow, what a clickbaity title. The article just states that Tim Cook prefers a different mouse than Apples's own Magic Mouse. Now that might be because he finds the Magic Mouse bad.…

Chrome removed support for JPEG XL last year, see e.g. https://arstechnica.com/gadgets/2023/04/free-software-group-...

I just activate reader mode on his pages, works great. (Not disagreeing with you, just stating another workaround) Also wish his pages had dates on them (one or both of first poste…

Well, Qualcomm at least claims that. Whether they can deliver is to be seen. Wouldn't be the first time they fail to do so...

Well... "it appears to have fallen on Fedora and GCC developers" suggests they are are forced into doing this. But it's the reverse: they decided this is a sensible goal. OK, they …

That's not 15 minutes per host; that's 15 hosts per minute.

A bit off-topic, but: I am somewhat confused by the claim “Subversion was created by Jim Blandy”. I was around back then, and the names I think of when it comes to “who created Sub…

Sorry, I was unclear: I know what weakly solved means. What I find curious is that the title and abstract refer to "solved", and don't mention what they actually mean. To me "solve…
