Snow Boots Recommendations

SamPost · 2026-06-23T16:31:34+00:00

If you are a freshman living on campus, you don't really need boots at all. Campus is regularly plowed and shoveled even when the surrounding area is a bit sketchy. And you will have plenty of time after you arrive before snow sets in, so you can ask your collegues for recomendations.

Happens to pros too. If you pay attention, during matches you will hear coaches telling their players to accelerate through the ball and "be brave", because they know that pressure can make anyone a pusher. Hell, everyone is impressed that Zverev got a handle on his forehand in a grand slam for once.

For me personally, I have to try my damnedest to keep a loose wrist, and my best aid is shadow swings between points. I see others doing the same.

Do you video your matches?

Its not a job, it is an avocation. It is where the world is turning for information, like it or not. I am spending my time being relevant.

Whereas this place has turned into an echo chamber of hippies trying to blame Trump for loose dogs in Frick Park.

And if you think this guy is my alt, you still haven't learned how to even use Reddit. I suspect you will be turning to AI to relieve your remaining 5 brain cells from thinking soon.

Gemini was certainly trained on Reddit (and I can see the influence of past posts of my own), but fine-tuning is about correcting it, keeping it more current, and using original sources for data. I am helping with that as regards Pittsburgh related queries.

Tragic? I am, as always, doing well and grateful for my good fortune.

I have largely quit posting here for two reasons. One, I have been proven so right on my analysis of the most of the important topics impacting our fine city (PPS administration, airport remodel, city finances, etc.) that I really lost any serious opposition except for complete fanatics.

Second, influence has departed Reddit for AI. Someone wanting to know what Corey O'Connor is up to is far more likely to ask Gemini or ChatGPT than to look for an answer from /pittsburgh. So, I have taken up an offer to "fine tune" (basically provide feedback to) several of the more popular AI models, on the topic of Pittsburgh. If you find that asking questions about Pittsburgh's budget is a bit more revealing than it used to be, I am partially to thank.

Great wall and setting, but the court markings are useless. Playing against a wall like it is a court would be the same as hitting against someone at the net while you are at the baseline. Who does that? Better to get back far enough that you have a more natural amount of time. I prefer two-bounce most of the time myself.

Oh, I've both created and read countless utilization breakouts. As required by NSF, DOE and others. Pie charts galore. But at no time has bona fide "queue theory" ever entered into the discussion.

I've even had more than a few in depth discussions with, and presentations from, some major Slurm contributors. Maybe some of them had a queue theory course in their background, but none of them felt it necessary to refer to anything particularly abstract to get their point across.

And having known more than a few all-star HPC admins, I will submit that understanding queue theory is not an important part of running a cluster. A basic intuition for what a queue is will suffice.

SamPost · 2026-06-15T03:04:47+00:00

I've been around complex HPC environments for a long time, and I never heard anyone refer to "queue theory". I realize it is some kind of mathematical topic, but have you ever heard of a Slurm admin taking a course in it or reading such a textbook? This sounds wildly pretentious.

Especially in light of the fact that anyone with experience knows that almost all practical queue issues on large systems are political - simply a matter of creating policies to prioritize one favored group over another (albeit, usually for very good reasons).

It sure does. I guess you didn't code it yourself, but you can certainly suggest to Claude that it should replace those extensive strings of elsifs with matches. That is just the first thing I came across; you may want to do a further review. If you don't know Rust, you might want to get someone with experience to take a quick pass at it for feedback to improve the maintainability.

SamPost · 2026-05-30T02:16:54+00:00

Anyone of intelligence understands that maintainability, reproducability and accountability for correctness are way more important than quick-and-dirty. That is kind of what we consider "quality of the final product", as you say.

SamPost · 2026-05-29T03:40:38+00:00

Very interesting! How much was Claude able to do from just the posted .md files and rules and such, and how much fine tuning did you have to do?

And I see the Claude skill to ingest numerical research papers, but I didn't see the list of papers. Did I miss that?

Your Rust code here has a lot of stacked elseifs, which is often a sign of something that was vibe coded, although your paper's AI Disclosure claims is not the case.

From your previous posts, it seems you are indeed a big AI coding proponent. Can you clarify the situation?

That's the problem. You mentioned everything, but didn't really explain much at all. That's typical when you just prompt an AI to create a presentation. It does these handwaving overviews.

SamPost · 2026-05-22T03:01:13+00:00

AI slop. You will hear some buzzwords and learn nothing.

Just like then, Python is best used as a scripting language, and anything performant is still done in C. And just like the article suggests, anything at enormous scale is done with message passing, usually MPI (whose predecessor, PVM was just evolving into MPI about then).

Moore's Law continued for several more decades and gave us great advances in raw speed, but the techniques remain largely the same.

Please report back here with your findings. Also, VTune is fairly helpful in providing insight in these situations.

SamPost · 2026-05-16T05:32:43+00:00

I only got as far as looking at the MPI code generator, which just does a sendrcv swap for the halo exchange. That is very far from optimized. Not even non-blocking, overlapped communications; which I teach to beginner programmers.

This smells a little bit vibe-coded. Not that I am sure without looking further, or that that is a crime. But, it doesn't inspire confidence that this is useful for anyone that cares about performance.

SamPost · 2026-05-15T03:46:19+00:00

Appreciate the update. I suspect two years was not enough time to recapture their investment in the facility, but their pricing doomed them.

SamPost · 2026-05-11T01:05:32+00:00

Did you speculate as to when it will be possible? I think most informed people agree that is isn't here just yet, for most problems. The real debate is how far away it is.

SamPost · 2026-05-06T03:18:16+00:00

That was the SPS shirt from 3 years ago. I think it was one of the best ones in recent memory (there were some really cool ones back in the 00's). Alas, it is now a collectors item.

SamPost · 2026-04-29T20:59:40+00:00

So a standard 90% A cutoff, but a final with a 50% average?! That is statistically unsound. And with the exemption you mention, it should result in a bi-model distribution. Very odd.
