  • Problem: ambiguity of date terms like saying “this Wednesday” on a Thursday. Is the speaker referring to yesterday or the coming Wednesday six days from now? Not always clear.

    Solution: I propose standardising our understanding of the week as beginning Monday, ending Sunday. At any point in the current week, “this whateverday” refers to that day in the current week, no matter if it’s past or future. “Next whateverday” refers to that day in the upcoming Monday through Sunday week.

    “This Wednesday”, on a Thursday, is referring to yesterday.

    “Next Wednesday”, on a Thursday, is referring to a day six days from now.

    (I also suggest adopting ISO 8601, writing dates in year-month-day order to avoid that ugly ambiguity.)








  • I have a whole desk full of calculators. The two I use most are:

    Sharp EL-W516X A very capable little dot-matrix device, with some limited programming / macro ability. Performs all of the calculus, stats, matrix, and combinatorics functions I use regularly. This was my go-to calculator until I started using the…

    Casio fx-115ES PLUS At some point, I had to write some exams which only allowed a few calculators off an approved list. This was the one I picked from the list. It is a very competent little device which can do anything the Sharp unit above can. After getting over the novelty of having to learn a new keypad, I found it nearly identical to the Sharp in usage.

    I think that both calculators are effectively identical in terms of function, but the Sharp may have a slight advantage in terms of its interface. I would wager it takes slightly fewer keystrokes for the same operation on average as compared to the Casio. I also didn’t really take advantage of the programmable aspect, instead using the four keys for the common multipliers I use in my work: kilo, milli, micro, nano. I liked how the display would read in “natural” terms like “2 * pi * 10k * 100μ” instead of having a tonne of “10^n” terms in the line.

    The Casio has the advantage that it is typically on just about any approved calculator list; if you’re taking exams down the line, consider getting used to an approved calculator now so you’re not wasting time searching for buttons later. It’s also the more popular choice, I think. I saw plenty of students, TAs, and instructors using this calculator which could make it easier to give and receive help on it.


  • One of the frustrating things about Signal is its extreme compression. I hope WhatsApp laxing up a bit will be the final push to the Signal devs to allow me to send a 30 MiB photo if I want to. Just give me a damn opt-in option buried in a settings menu for Pete’s sake.

    Annoys me to no end that I’m forced to crunch image quality down. The reasons I heard in discussion were to save disk space and network bandwidth. I have no sympathy for either of these points. Have a modicum of digital hygiene and delete old files, and pressure your ridiculous governments to invest and regulate ISPs, then join the rest of the world in the 21st century.
