VALVe themselves have game IPs they want to protect. Within the boundary of "it's legal, wygd" there are always ways to make pirating VALVe games easier and VALVe will stand no ground to ban those.

If the situation is that bad and cheating is that easy, soon there will be researchers cheating all the way to Elo 2000, just like there are researchers submitting garbage papers to prove that some journals are jokes. That will be interesting too so I am not against your vision.

For the hyperbolic version area is the correct counterpart of arc-length. See the wikipedia for a picture. So only "ar-" and "a-" make sense. Blindly using "arc-" is like saying non-invertible matrices are "vertible" because "in-" negates the meaning of a word.
Re:Citibank may lock bank accounts for 45 days if breach suspected on Wednesday September 07, 2022 @02:33AM (#32747173)
I (and I assume many do) buy flight tickets with a credit card so at least one bank knows you are traveling. Never have I had any problem when traveling. But there is one time I wanted to wire myself from Bank1 to Bank2, got blocked, called to unblock, and got blocked again immediately after I attempt the same transaction. Have to goto a Bank1 branch and brainstorm what to do and they ended up giving me a "bank check" (what's that???) only for me to walk to a Bank2 branch to deposit.

Despite all the good contents, calling the inverse function of hyperbolic tangent "arctanh" just makes no sense.

This doesn't matter. You buy wheat at $100 and sell breads at $250. You net $150 and convert that to, say, €150.

Maths don't scale up. Moore's Law will catch up and eventually rendering math will be like rendering jpg. For now the priority is to get things to work so we don't waste extra time determining if we just avoid math or we use stupid PNG.

The AMS style guide[2, p. 117] suggests

I find these improves readability of my TeX files.

Re:The human genome is, at long last, complete on Saturday April 02, 2022 @08:34PM (#30893023)
After ten years of "we are getting to the last mile" and "we are finally completing", it just feels like bio people cannot give up this good reason when justifying their funding so we have to re-complete human genome every other year.
Re:Buttons as Finite Automata on Thursday March 24, 2022 @08:52PM (#30797521)
You are designing a "prefix code". It is a collection of strings of button presses such as {A, BA, BBAA, BBABA, BBB, ...}. Each string maps to an action.

Ideally no string is a prefix of another string. Even more ideally any infinite sequence of As and Bs can be decoded into a sequence of actions.

You get to choose between out-sourcing the liability or naked-running. You can even linearly-interpolate between the two extremes. In case of banking, you already payed the hidden fee (banks get bailout using government money, aka your money)
I guess I know why the parent is downvoted but in the end the responsibility is on both sides. If you don't speak fluent English you ask for interpreters in Spanish, Chinese, you name it. You can't insists on speaking an unpopular dialect/accents, can't even specify what best describe your dialect/accents, and expect anything from the hospitals.

In vscode, tab (the key above capslock) is implemented by counting how many characters are on the current line and adding 4floor(x/4+1)-x spaces to the current line.

This obviously doesn't work if there are non-ascii characters that (have to) use a different font and hence having different widths. Or if you prefer variable-width font, then a purely ascii document will break tab.

The developers reply on github that this (characters having different widths) is a frontend thing and they don't have enough API that can fix this. But of course since vscode is an open source project you can always fork it and fix it yourself.

I don't know any other editor that cannot handle tab.

There were days where seeing a unique doodle makes your day. And then one day you realized that there is an official page for all doodles and you spend a good time on it. Now it is just PR department yelling: we didn't forget it's international trans-women day etc.

I mean we do have a lot of (perhaps too many) markdown dialects today. Wikipedia, wordpress, github, stackexchange, you name it. Last time I was using a Q&A forum for calculus course, it uses $$ to start and close a MathJax div.

Pay respect to the author and also to people who use the word and want easy pronunciations so they can spend more time on what's more useful. If, say, our lovely Indian instructors on youtube decide that gif is git but with f, then let it be, for that they are making contributions.
But that's exactly the reason why healthy people, whatever healthy means, should starve: If those who can control their asses do so, then there are more toilets available to those in need.

Re:LaTeX Finite Automata and State Diagrams with Tikz on Wednesday December 29, 2021 @03:06AM (#29722902)
The TikZ style should really be the default standard or even the bottom line. Last time I check Google Slides still doesn't understand how to connect two blocks of texts. I have to manually choose among four points (north/south/west/east of a block) to start or end a line. Whereas in TikZ the optimal point (among infinitely many points that constituent the border) is chosen.
It is in geometry one can experience a spectrum of evidence from a picture (animated or not, interactive or not) to a line-to-line modus ponens proof. Not to mention the historical value that Euclid invented a literary genre that is now called "proofs". Good luck teaching kids "more useful" stuff like data science and quantum computing. High school teachers don't understand these topics and are more likely to teach them ineffectively. Now that's harmful and no one can blame geometry anymore.
