@MagicOctopusUrn Under Windows (hopefully soon under Linux and macOS too) you can just type ]chart mydata to graph anything in an interactive GUI. You can then export as image file or SVG, etc. Generating the files works on all platforms already.
@MagicOctopusUrn Well, APL itself is almost our only "product", and we license it for use by very large enterprises (and very small ones too).
@Adám just wondering, what your biggest consumer base is? Is it AI? Accounting? Insurance? Etc... Cool if that's not public domain, but that's been my major question; who is using APL to the fullest extent? In what domain.
@MagicOctopusUrn I'm pretty sure finance is Dyalog's largest customer section. E.g. SimCorp and AMECO run on Dyalog APL. However, production management is also a major APL sector, with representatives like Volvo Penta, and also one of the world's largest oil companies (which does not allow us to mention their name for fear that their competition will pick up APL…)
@Adám - oh interesting that there's a font-to-back integrated system in APL... kinda what I've done (in-house) over the years using Python. Am about to start at an exchange working on their batch jobs also using Python. Python is everywhere in finance that is not real-time / low-latency where C++/Java tend to take to the stage; but I'm yet to encounter any APL.
@JonathanAllan Most companies keep their APL to themselves. They train their own workers, and guard their code fiercely. Btw, have you heard of Py'n'APL, the new APL-Python-APL bridge written by PPCG's very own marinus?
@JonathanAllan Sometimes Dyalog APL is actually faster than optimal C – which is of course impossible as Dyalog APL is implemented in C… However, those financial institutions that need real speed use K, which is also a type of APL, but with everything removed except that which is essential for financial databases. K is usually faster than C, despite also being written in C.
@JonathanAllan One of the world's largest providers of financial services have their system written in Dyalog APL, but again, I'm prohibited from saying which company that is.
HFT shops often use C for their algorithms from what I've seen - and they are the ones who are really battling regarding speed of action (so much so that they run specialised hardware too)
"financial services" covers a lot. JPM were using Java for their high frequency FX trading (I sat right next to them).
@JonathanAllan Right, but writing in C has a huge downside: If the market changes, and the models need updating, it takes much too long to rewrite and recompile compared to rewriting in K. The K interpreter fits in cache…
@JonathanAllan Morgan Stanley wanted APL to be customized to their needs, so they created a dialect called A+. Later that became the basis for K, which was then spun off into a separate company, Kx Systems.
My government teacher's idea of a good lesson was to turn on CBS news (90% sure it stands for Certainly Biased Sources) and have us write 3 sentences for each issue they talked about.
In the end after 50 min of news 6 sentences were written
@EriktheOutgolfer Scroll down to "Switch to a Different Channel of Chrome in Ubuntu" and you'll be able to get back to 60 I believe... howtogeek.com/howto/21282/…
So my dad calculated that Social Security tax (if you get paid out in full) will end up costing you about $27k a month. If you invested the amount you pay in social security (assuming you max it out) according to projected F&B500 growth rates you would be getting ~30k a month instead of the social security 3k a month

I stayed up until 1 o'clock waiting for a tennis match to start. Then, I stayed up until now (2 o'clock) assuming they're just being slow. I look at the schedule... The match starts in 3 hours... facepalm
@ATaco userscript request. Poll board. When a strawpoll link is posted it goes on a board of the 5 most recent strawpolls and displays on the side or smth
