I am so sorry it is this way now. I personally believe if you have imposters in the class who intend to learn nothing it degrades the experience even for the highly motivated. Humans want to be in incentive-aligned learning experiences.

I had one fellow in the back of the room at UF in the basic algebra 1 course(!) who began the semester by once or twice a class doing a reasonable impression of a mooing cow. I kicked him out. Didn't happen again. Classroom atmosphere had better vibes after that.

Why would you grade math homework? I taught "intro math"[1] through algebra and calculus to linear algebra at UF and ASU over four years as a paid graduate TA. This was the middle '80s. I assigned homework from the text every class. At the beginning of every class we (the students and me) worked through any particular problem any student wanted. That was 15min, max. Then I lectured and assigned more homework. I graded my own 3 in-class closed-book exams and final exam.

Based on the classes the Math Department gave me (very satisfying) and the student evaluations this seemed to work more or less fine. I was a brutal grader though, some of those entry level classes had bimodal distributions with 'F' being the low mode.

I also showed up for office hours and did my best to help people learn by digging through their questions.

I don't see why this methodology wouldn't work fine today. I wouldn't care now how a student learned. Show competency on the human only test and we're good.

I had one student who achieved a solid 'F' come by office hours after the course to tell me how much he enjoyed my teaching. Whatever!

Anyway, teaching that way, with the positive interactions with students interested in learning, was one of the greatest experiences of my life.

[1] An absolute pedagogical shitshow that wasted everyone's time for zero gain.

AirBnb is camping. I have been travel camping with and without people for 50 years. The longer you camp the better the experience. Almost all of the first 25 years involved a tent (or bivy sack), and maybe a camp kitchen. Then you surface again, happy minded, into a world where people travel but they expect everyone touching their utensils or even maybe food(?) have a "Food Handler's card or certificate". Whatever that is. Back into the bush.

I started grad school at math in Sept. 1995 and:

"There's never been a better time to go into math" was the final statement of the ten minute orientation session from the Dep Chairman.

It was a great thing to do anyway.

Then.

Ah. So now we are talking about multi-precision libraries, which their basic reason for existing is that different precision formats yield different economically interesting results, via a variety of a not-large set of economically interesting tradeoffs.

The 80 bit format was an at-the-time (ATT) engineering optimization that made ATT double precision (DP) more attractive given the better round-off behavior, at "no-cost".

So the interesting question here (that I don't know) is: is "deterministic" quad-precision (QP) as the accuracy upgrade from "non-deterministic" 80bit internal DP, always better economically?

Depends on what the computational problem is, given a budget. And that budget buys things that are only available on the market.

I used to think technology monocultures were a good thing but given the current state of things I have reversed myself. I am happy that life has simplified for you though.

I've been watching, lightly, interval arithmetic for 40 years. As you know algorithm sensitivity information is mandatory. We used intel 80bit FP do evaluate that, slowly, back in the day. We didn't use interval arithmetic, though we knew about it. It wasn't economically viable. Hey C++ what can you do for us? Templates, damn.

How important is interval arithmetic, economically, now?

TY. I am ignorant of the compiler side of the process here. My mental model as a former numerical algorithms guy at the time was that the x87 chips performed the 80 bit operations as opaque internal operations, and returned the visible results back as 32/64 bit IEEE754 floating point format bytes.

Is that inaccurate? If not how did you store the extra 16 bits (DP)? I should've bought a zortech compiler back in the day? ;-)

I am sorry that Borland hooked me with turbo-p and then jacked me up with turbo-c/c++.

Aha! TY. Sun's floating point people were world class but I still think this was a dumb thing to do.

With the NAS Parallel Benchmarks we were trying to encourage as wide a diversity of hardware and algorithms as possible so we were lenient with the acceptable "valid" interval of "correct" behavior. I've already discussed heretical Cray FP. Those were fantastic systems. No way would we disqualify some weird/different algorithm/architecture if it meaningfully advanced the SOA in performance/efficiency. OTOH wars were fought over having any firm accuracy requirements at all. So this jvm thing looked... pointless at best?

This is all nostalgia for a past that actually was. Those were the days my friends.

"numerics people ignored it"

I dunno Walter but as the first(?) IEEE754 implementation in a PC system it seemed like a pretty damn big deal to us people working in numerical algorithms. It was a big enough deal to me at the time (I was in graduate school) that I've kept my 8087 chip all my life and have it before me now. I see the old boy has lost a pin during the last move, dammit.

Chip has "3716150AA MALAY BEV 22" embossed on the pin side. Search gets me nothing.

I just went to zillow and typed in my zip and tried two different filters for single family homes priced between $300K-$550K:

Listings:

No HOA fee: 32 up to $500/month: 62

I'm not going to bother because this is an HN comment but I think you can imagine what happens to the results when I specify newer than say 1993 (when my house was built).

I have an HOA, but it seems defunct. Everything we do to the house, if visible, can be interpreted to mean I must get unanimous agreements, in writing, from all my neighbors.

It turns out I managed to land right between two asshole neighbors (constant trespassing, dogs, etc)

Ok, I have not indulged in the new paradigm of work your way to the interesting stuff. I just did occasionally dabbling back in the day, but I wonder: I fully understand the intent of making a prospective good citizen demonstrate commitment and the level of service-side management effort to make this social network paradigm work.

But isn't this sort of structure just completely transparent to [Nation|Narco]/State Actors? Feel free to widen the set of economically interested actors.

How do you scale video interviews?

I think I am missing something about this scene. I really want to dive in tho.

Can't you replace the keyboard? (I'm assuming "workstation" != laptop). I have mechanicals laying around that I would just haul with me into work.

"... seems to be ..."

Compared to what? Your string of comments are banal generalities that may or may not apply to this particular situation. Where else in this world at this time, is this particular governmental failing handled materially better?

Singapore? China? Russia? Switzerland? England?

I have sometimes learned interesting things from you (as a commenter) but there is nothing to learn here. It appears to be only diversion and distraction.

"here"

It's a big world out there, whatever "here" means.

That last sentence makes me wonder, do you enjoy ads?

I went to a Super Bowl party a while back and the half time show glitched continuously. Random weird glitches for the rest of the time. => note to self: don't pay for this.

Huh, two houses back I had a really fucking POS dryer that I got expert at replacing the "Dryer Thermal Fuse" (pick your own youtube video walkthrough) and my foggy memory says in my ear that it was an LG dryer. So I'm thinking, this commenter malfist, doesn't know what he is talking about and I'll go look in my notes.org and... NOPE! It was a Samsung DV42H5000EW/A3 model!

Sorry malfist for thinking bad thoughts. I've redirected all that negative energy back to its rightful owner: Samsung.

The washer next to that dryer was an LG, and in my notes I never touched it.

Always good to reattach to reality.

Ah, I see that the washer/dryer pair we bought new 4 years ago and hauled across the country are LG ThinQs. Very happy with them. Apparently can be "smart" but I shut that down.
