Interesting. Maybe I'm significantly older (graduated high school in the early 90's) than the poster, but math team was a big deal at my high school. So much so that my school fielded 3 teams (A, B, and C) for regional competitions. At local meets, A and B teams typically always came in first and second respectively, with C (only a partial team) coming in third or fourth. A team also won the state championships twice.

In general, it was pretty low key. Local meets were every month or so, practice was about 2 hours a week, though we did more for states. At no point did I think about the impact on my college admissions, and I don't recall it coming up in conversation with anyone else.

(warning: humblenrag) In fact, the only real negative memory I have was that the individual high scorers got graphing calculators until the year I had the high score and got a calculus textbook. Of course, when I got to college and had to pay for textbooks, I learned that the calculus text probably was more expensive than the calculator.

I'm guessing 5-10 years. However in 30 years the opposite question will be the case - if you are driving a gas car you will have to plan ahead. As EVs take over gas stations will start to disappear.
Love how the demo falls pray to what I dont have a term for, "the SQLers assumption"?

It asks ChatGPT to write SQL to get sales data, ChatGPT (or most SQLers) trust that every year-month combo has atleast one entry - which means the graphs its presenting could be wrong. Because if there was no entries for a year-month it it will skip that year-month and make it look like you never had a 0 month.

I've made this mistake before in prod, and without some janky lookup table of every date in existence... you need more code :( Fairly few people actually notice the potentially missing month, but still its a bug n a bad one.

Looks cool regardless though, good luck!
Thanks! We're still benchmarking Robin Hood hashing and are open to further experiments. The benchmarks look promising.
This is already a reality with the fully electric self-driving tech we have now: trains. And no, people still dislike long commutes, even if they can play steam deck on the train.

This framework of retrieving information , analyzing it with program code as an output , programming machines to do something , retrieve information about the output of the machines , analyzing it to see if it matches the expectations and if not repeat and rinse until you get the perfect outcome ....

seems useful in general for all kind of AI agents. Is this framework open source yet?

Fair enough! Thanks for explaining.
What you are doing is inspiring, I'm currently a student with not so much money but doing somthing like this is definitely on my list when I can afford it. Thanks for doing it and also the Idea. I'm sure, as you know, that there are many who are grateful.
There are zero incidents historically of a launch complex being a meaningful driver of a billion-dollar natural disaster loss. It's not a thing; it's not what's driving the increase in expensive hurricanes and Florida's insurance market.

No. Apologies if you aren't familiar with hyperbole, but it's very common. I might even say everyone does it all the time.
Elon Musk single handedly pushing usage of solar and reducing fossil fuels in cars. Jeff Bezo drove costs down for consumer products. Peter Thiel and Elon at PayPal reduced financial transaction costs... and then you're complaining they didn't do enough?
Yes, a bit silly this. Code is means to an end, it makes sence to think of code as liability (maintenance cost, inevitable bugs, etc .. ) but this must be contrasted with the value it provides within some reasonable timeframe.
Indeed, it was before my coffee when I posted and I rushed the info out. Mea culpa.
IMO that would be better solved by mandating tap and pay payment at EV charging spots. Integrating payments into the charging standard feels like a wild overcomplication by comparison.

Seems like it would be to me. So long as you monitor your battery charge you know the vehicle will get there and it can tolerate many imperfections in the tube. Pneumatics need a tight seal to the tube and thus cannot tolerate imperfections.

Are current prices going to stay the way they are? Normal people can't afford homes right now.
Thanks, Gavin, I'm pleased to hear that. And thanks for recommending my blog!
Nice. I will definitely be taking a look at this. Have you looked at the xformers library ? They are looking at the same problem as you but their focus is more on providing performant transformer modules using triton. Using specific components from the library though is not as simple. I kept running into runtime errors so I've kept it aside for now. I am building something based on the Bert architecture so I will give this a look. Thanks for all the work!
Some people are paid to be available on demand, not to continually produce output. Somtimes we pretend that its not and come up with some busy work, but most of the time you are cheper to have on a payroll than to hire consultant on demand. So tou spend some of the time idling in HN.
I don't. It's too mentally taxing for me.

I save all my notes in Obsidian, tag them appropriately, and don't worry about what folders they end up in. I use the Omnisearch plugin to search for what I need.

Lately, I've been using the Dataview plugin more. I create auto-generated Index pages on different topics. For example, I have a page called "Python" with the #index tag and the following dataview:

```dataview
TABLE file.mtime as "Last Modified"
FROM #python AND -#index
SORT file.mtime desc
```

I also have index notes called "Later" and "Favorite" in Obsidian. They use a similar dataview query, but with their respective tags instead of #python.
Thanks for this, I'd been going off the previous articles on this, and hadn't realized it had been reverted.
Technically, every element that's not in the shadow DOM is a global. But yes, there's plenty of ways to implement this and an argument to had for most of them.

I've done a fair amount of road tripping (~15k mi over 1.5yr) along the WA/OR/CA/NV corridors where Electrify America is dense enough to use solely, which is convenient since my car came with 2 years of free charging from them.

Ignoring their pervasive station reliability problems, their app is pretty bad and only barely functions.

* I've had to skip a perfectly functioning station because the app thought I was still charging from the previous time and wouldn't change its mind about it.

* Their Carplay app has literally never worked for me, not once (usually it shows me still charging from a session >1wk ago even when the regular app doesn't, sometimes it doesn't boot, sometimes it shows me as not logged in. The main screen has never once rendered.).

* One of their level 2 stations (which tend even less reliable) existed in the app on about 50% of refreshes.

* The app requires a pretty solid signal to work at all since it seems to consult their API to query for stations near where you are and then you guess at which one it is ("is this the target one or the mall one? it's the target that's in the mall?") which is pretty silly when you're parked at the station so it's in range of your hands and eyes.

* I eventually figured out that I can add the EA plan to my Apple Wallet and tap the phone instead of ever opening the app, but that seems to randomly select between the "free" plan (rather, included in the purchase price of my car) and the $10 balance that they make me maintain for god-knows-why when at California electricity prices no charge has ever been below $10.

* The stations have credit card readers which I've never tried to use but almost always when I see somebody having trouble at a station it's because they're fighting with that thing. I assume EA's response would be "just use the app, it's so much better"

That's all just one app, not a slew of them for every charging network in my area (which also includes at least evgo & chargepoint just to cover the big ones). The sooner this app bullshit can die the better.
Well the C++ segment is important and from what I gather, ROCm is failing at that. AMD would be a lot better off if the C++ part worked, even if the other parts don't.
Yes, that's what the rest of the comment says – that the people left due to a change in the social dynamic.

If that happened, we would all go back to blogging and web rings. Don't doubt the laziness of office workers.
QR sticker manipulation is too easy of a vector for me to take anything seriously when it comes to "just scan the code, enter card data, and carry on" is just too easy to fake. it's even easier than credit card skimmers. I like QR codes and their convenience for non-critical things like marketing. For things that are direct payment links it is just too unsecure for my comfort
Interesting how this work received an homage in The Name of the Rose, up to the name of the librarian, Jorge de Burgos. (I hated the way they pronounced the name in the movie, /'iorge/ instead of the correct Spanish way /'xorxe/)
How do you go bankrupt as a company renting powered scooters, which are possibly the cheapest possible mode of transportation just above a Craigslist bike? Incredible
I used to work at NASA (contractor) doing this. One thing, get a job in the field. If you really want to, apply to Marshall Space Flight Center and / or Ames (Top500: Aitken [#85, 9.07 PFlops], Pleiades [#132, 5.95 PFlops], Electra [#143, 5.44 PFlops] systems) on either the Federal or Contractor side. GRC, LARC, and JSC also have some. At least a few years ago, the Contractor / Federal integration was actually quite good, and nearly transparent (except for allocating money). These groups are both fairly well known at NASA (MSFC, Propulsion Structural, Thermal & Fluid Analysis [2][3], and Ames, Entry Systems [4])

When I was there we were running ~100 million cell (vehicle) or (vehicle + pad) Hybrid RANS/LES sims with moving overset grids, maybe 10-20 species reactive combustion chemistry (SSMEs and SRBs lighting together), and Lagrangian evaporative particle dynamics (launch water suppression) using Overflow/LARC [5], or Loci/Mississippi State University [6]. Note: My info's a decade out of data, so no idea what the SOTA is these days. More than this.

If you're interested in the field and what a lot of the industry is concerned about, then while old (2014), the CFD Vision 2030 Study is not a bad orientation. [7]

Try to get a ticket to Supercomputing and go wander around. This year was in Denver. [8] Their focus tends to be on "large" though, so you'll mostly get massive weather simulations and stellar cloud dynamics. I like the conference, yet its difficult to get any notice unless you did #CPUs/#GPUs/#FPGAs++.

How long does it generally take between model architectures like Mamba being proposed and the use of these architectures in SotA mega models like GPT or Gemini? IIUC Mamba basically eliminates restrictions on context length which would be awesome to see in the super-mega high performance models.
I can confirm, in classical mechanics, flat gravitional fields give paths that follow quadratic trajectories.
For most EV's (specifically Tesla) the battery is a structural component of the vehicle (for better or for worse).

Would require a complete architectural shift. Also, they would be incredibly heavy and difficult to swap. Would require multiple smaller batteries. People would abuse them. Would require huge inventory of batteries all over the place. Imagine going on a long road trip, you wouldn't bring batteries with you. You'd swap them along the way. What if a particular vendor/station is out of batteries for the day? Or doesn't have your particular flavor of battery because (like we have seen with charging ports in this exact story) manufacturers couldn't agree on the interface/size? Or the batteries they have are abused and low quality / at end of life? This is very common with scooters. It would be a shit show.

On the other hand, electricity is essentially fluid. It does not require a container. As battery tech improves and as high voltage charging becomes more commonplace, plugging in to charge won't be so bad.

Honestly, a huge part of the realization for me was that a majority of my notes are not worth reviewing or keeping!

This is probably just to do with the way that I note keep, but so many of them are junk.

So instead now I take notes on paper in a notebook. A vast majority of them always stay there. Maybe 10% of them get converted into digital notes into Obsidian.
that's the solution to all Windows problems, so yes :)
I admit, I definitely have curiosity.

I have not had to act on the data yet but if I were to get a low O2 alert while flying I would definitely open a window and descend ASAP. Depending on the circumstances I might also consider landing.

I've also played around with the Rust version egui, and with the eframe template it's super easy to bang out super quick GUI tools on github pages (for example, I made a basic guitar fretboard chord finder [1] to help me learn guitar in a few hours, plus a few more hours refining it)

The mental model of immediate mode guis makes it really easy to work on it as a side project with 10-20 minutes here or there before bed, though doing proper layout to make it look nice is sometimes a challenge. The other advantage is that I can just jump into the implementation, and the egui code itself is pretty easy to grok.

Sure, if you put in a lot of effort you could probably make a professional app with it. You'd need to recreate a bunch of features that come for free in more "bloated" UI libraries. But you could do it! More likely, though, is that you won't and your "professional" app will just end up being bad for lack of those features.
Sounds like you and your fellow community members should vote for folks who will prioritize public transit rather than widening stroads. Poor transit options are a policy choice, not an inevitability. The best time to start advocating for livable cities was a decade ago. Second best time is now, so that ten years from now, you and yours will have more options than they have today.

Folks need to be transported at higher and higher densities as a city's population grows. Cars are the lowest density carrier available. Think of how many cars fit on a four-lane road on a mile stretch. How many people are in those cars? How many trains or busses would be needed to move that many people? Now visualize the space taken up by those cars versus the space taken up by busses.

That's how you solve traffic problems with a growing population, even for the folks who still need their cars because their destinations are sufficiently irregular. Mass transit helps those who need their cars too!

As a byproduct, you don't need so many and so large parking lots. Think of all the parking lots around you, which I'm sure there are many. Imagine 80% of them were replaced with housing, retail, office space, parks, meeting places, etc. Then convert the remaining 20% to multi-story parking.

Urban sprawl is a choice. Choose different.

The high school math Olympiad team is the fondest memory of mine. It was like solving puzzle games every day. But I guess if you are forced into puzzle games when you don’t like it can be a torture. I also changed my career to tech but I still look fondly back into the days when I could be immersed into solving problems without getting pulled into various meetings.
Fair point - I just don't want to be forced to use it.
"This is nuclear winter for everybody who doubted ethereum," Thielen wrote... blah blah blah... shorts getting squeezed.
I’m pretty sure that a lot of people are going to end up going down rabbit holes that waste a lot of their money chasing the golden payout on AI, I also don’t think it’s our typical bubble.

Microsoft owns 49% and we’re already seeing its usefulness in the world of enterprise organisations where Microsoft is frankly becoming irreplaceable on the office side of things. We’re only in the early stages of using Copilot, bing agent, 365 or whatever it’s called, and it’s rapidly changing our “boring” business processes. It’s things like having it listen in on Teams meetings and write summaries. Making non-ugly sleep inducing presentations in a financial company focused on green energy… seriously… It’s replaced all our external spending on corporate designs, it’s not on par with what you’d see on top of the line communication, but it’s good enough to send out to our investors. It’s also good enough to replace any form of icon libraries and stock pictures. We use it to enhance excel (not sure how exactly, and I’m pretty sure I don’t want to know considering what lives in our shared excel sheets isn’t supposed to live there). It’s helping more digitally inclined PMs and business people automate a lot of their processes in ways no other no-code or RPA tool has ever done before them. It’s helping BI write shitty software, which is perfectly fine since we can always re-write the stuff that needs to be efficient and maintainable. And so on.

But it’s also just part of the Microsoft package. If you or I buy into this, or even smaller companies do, you’re going to pay the prices listed by Microsoft. That’s not how enterprise pays though, we go through these 3rd party dealers with all sorts of fancy certifications and whatever that they pay to have, and then we buy packaged subscriptions on things we need. Of course if you compared, we probably pay more, but it doesn’t look like that on the budgets, and that’s what matters when you roll these things out. So for us AI is similar to how Microsoft Teams became our only communications tool. Not because it was better (at least not at the time) but because it was “free”. AI is also “free” for us, and because it is, it’s going to lock us even harder into Microsoft as a vendor. It’s not like there was really an alternative anyway, but now there really isn’t. And that’s not a bubble, it’ll only strengthen Microsoft unless EU or US regulation does something about it, but how can they when they’re using these tools themselves?
Life-cycle hooks typically run as side-effects from state changes, so that would be your route to do something similar.
