There are different applications for tubes. Snobefest audiophoolery will complain they are "not like the originals", but people buying them for nice distorted guitar sound will be entirely fine with it.
that's good to hear- my hands like to wave and I tried hard to keep them at bay
My two cents.

We do a disservice to students in the US by treating Algebra/Calc as advanced math. Typically, American schools judge student math aptitude prior to algebra based on rote memorization of multiplication tables. Potentially with the added benefit of more rote memorization problems if one is in the honors curriculum. Aptitude for this type of problem does not directly translate into aptitude for higher math.

There is nothing particularly advanced about Algebra or Calculus. At most, it's a question of how much time one is willing and able to put into the subject. The fact that most American students do not exit high school with a functional knowledge of single variable calculus is purely an artifact of our curriculum priorities.
https://d2l.ai (Zhang et al) is a very nice book with the right amount of theory and tons of code.

If you want a bit more than just DL, and better foundations, https://probml.github.io/pml-book (Murphy) is the place to begin with.

Personally, I think a broader perspective, such as the one offered by the second one (Murphy) is the way to go.
The impression of rarity? They are expensive because of actual rarity.

These things are highly labor intensive to make and producing tubes with a consistent level of quality requires extreme attention to parts tolerances and procedure. Do you buy tubes or are you just opining on something you have no experience with? I would kill to be able to get a pair of good 300Bs for 100$
Anxiety is really the crux of it. My psych prescribing anti-anxiety meds was life changing!
That would be an incredibly wild & amusing twist. Unexpected Skylon reference!
I'm don't underestimate it at all. There's a certain warm tone that tubes produce. It's gentle in a sense. A DAC can be harsh.

A naive view point is that the analog output of an analog device is going to be smooth.

The digital output will add noise on the stair step transitions.

I'm not saying this is the case in reality. I'm just saying, it's useful to think about when dealing with analog vs digital signals.
This must be the 'big data' I heard so much about.

LLMs in general, I mean. They seem to be the first widespread application for large, unstructured datasets. Still hype-y, but maybe even a /practical/ application.
Funnily enough, same problem with trying to emulate CRT on LCDs
Talk about bearing it all for your country.
That's true, but you can prompt the LLM to sort by other criteria and it will happily oblige. e.g. number of syllables, how posh the word sounds, or in this case relevance to the context.

From the post:

> The training was done with PyTorch FSDP on 8 A100 GPUs in one day.

> We employ SkyPilot managed spot to reduce the cost by leveraging the cheaper spot instances with auto-recovery for preemptions and auto zone switch. This solution slashes costs for training the 7B model from $500 to around $140 and the 13B model from around $1K to $300.

So, this is using for example a2-ultragpu-8g (8x A100-80GB) on GCP using spot instances. You can use SkyPilot to quickly see the price is $12.8 per hour (~$307 for a day):

» sky launch --gpus A100-80GB:8 --use-spot

Serious question - what if I want it to hallucinate? If I want it to make a story about something ridiculous/impossible?

I'm pretty sure I could pay hush money to a porn star and nothing would come of it, even if I blogged about it incessantly to get attention.
Sorry my comment about banning was a bit harsh.

Re what tipped me off: gonna stay security-through-obscurity on that for now :)
You know. Life and money are only temporary in this universe.

If it becomes a hand me down to your kids, well that makes it even more special.

YouTube is probably the best source of education delivered by passionate teachers at this point.
Inciting a legion of goons to attack the White House is one thing, but paying hush money to a porn star is on a whole new level; that just can't be ignored. No siree.
I was pretty annoyed when I got to university and figured out that math could be about proofs rather than calculation. If I had been raised with that idea of math, I would have loved it so much sooner and would probably be pretty good at it by now.
Cool product, I could see it being very useful for small teams.
I gave it the old college try a few years ago out of some weird retro desire to use something "cool" like when I first found Linux in the late '90s. It was an obnoxious hassle nearly every step of the way, but I stuck with it as long as I could stomach. I did what felt like some pretty substantial work trying to update a port, and my issue just sat with no responses for months until someone else came along and independently re-did the work for a newer release.

The running joke about Linux is that next year is perennially the "year of the Linux desktop", but by comparison, FreeBSD feels like it's a decade away from achieving that kind of maturity outside of the server/middlebox space.
Sounds like the guy needs of a dose of Raylan Givens: "If you run into an asshole in the morning, you ran into an asshole. If you run into assholes all day, you're the asshole."
Sorry but I seem to have misunderstood the capabilities of WebGL 2. I had read that WebGL 2 was OpenGL ES 3.0 and that “OpenGL 4.3 provides full compatibility with OpenGL ES 3.0”. Which means OpenGL ES 3.0 can run in an OpenGL 4.3 environment. Not the other way around… whoops

The OpenGL versions and variants have always been confusing for me.

WebGL 2 is close to desktop OpenGL 3.3. So probably far too outdated for this project.

My taste, my pianistict abilities, my arm, shoulder and body movements and my musical idea for the interpretation and imagination of the sound of the piece can not be seen in a photo of my hand. Not even a good teacher can give you a finished perfect fingering for you, I doubt that a dumb machine can do any better, especially if it plays that bad as the examples sound in comparison to a even beginner human. You have to find the fingering out for yourself and this is part of the great joy of playing / learning piano.
On the other hand you don't have to worry about people complaining that you are ruining it by, metagaming, skipping the story, rebelling against other players, etc.

I think this should be emphasized more, I don't think it's just a matter of preference, not separating packages between projects using virtualenvs will land you in a world of hurt as soon as you want to update or uninstall any of them and they're hopelessly entangled with system packages and other projects.

I get the impression that there's no explanation required for how all the forces of the most powerful government in the world and its intelligence agencies, which are the largest, best financed, and since 9/11 least restrained in the world can't prove the liberal claims of a vast array of crimes that a slightly stupid wrestling valet game show host who largely lived off branding agreements with real estate developers committed with the aid of a small network of self-serving d-list dipshits.
I deleted the Nuremberg comment before you replied.

What's allowed in self-defense, or defense of another, isn't allowed in offense, in most countries of the world (e.g. "Stand your ground" laws). This is partly why Germany was justifying its early invasions as protecting German residents of those countries. And is definitely why Russia is so justifying its invasion and annexation of Ukraine and Moldovan territory.
Trump is a fundamentally different player than Bush or Nixon. They were establishment in times the establishment wasn't nearly as hated as it is now.

This just plays to Trump's strength as the ultimate rebel.

In terms of game theory, this is a very different game than Nixon or Bush.
Trump annihilated the Bush Legacy, and is hated by both sides of the establishment.

At this point - perhaps just to be the glass half full guy - its best to see math in the public school system as the equivalent to PE (physical education).

The kids (and parents) who really want to excel in STEM will just be doing after school competitive math anyway and probably are already so just like they don't provide competitive soccer/football/baseball/fencing/piano coaching (which also could be used to get into elite schools); the school district maybe doesn't need to provide anything beyond the equivalent to getting some fresh air. Perhaps even the lack of rigor, might increase the market size/volume for rigorous after-school offerings.

Yes and no. Sometimes you get contracts that require “source code escrow” so that companies can run your source if you ever go out of business.
Cool story, thanks.

They were pulling tubes out of what, live telephone circuit amplifiers? And what are these 23" bays nowadays, racks for equipment in telephone exchanges?

Never will happen. The US controls military power around the globe for now.
I wonder how much of this is a byproduct of school administrators themselves not understanding algebra.
This is not true - at least not any more.

Congress does get extra power when a law is passed as a treaty. Issues that are state business under the 10th Amendment become federal business.

But it’s nothing like a constitutional amendment.
Excellent recommendations, I'll also add if you're not in a hurry Edcor makes excellent transformers (plate, filament, combo, output, interstage). Everything's custom made when you order it though.

Hammond Manufacturing makes a lot of applicable transformers for the mid-to-lower range of hifi and they're largely stock items.

See if you have local hamfests. Tons of tube stuff there.

Remember, it doesn't need to be an audio tube to pass audio! My most-used amplifier is built around a pair of 6T9 TV Compactron tubes (basically the IC of the tube world, multiple elements in a space saving package). The circuit came out of an old GE vacuum tube manual. As long as you don't tell the electrons (or audiophiles), they'll never know!
Public school is no longer enough, and I don’t see it improving in the short term.

I think the only practical solution is widely-known resources and alternative curricula for low-income families so that they too can get a decent education. Hopefully people are working on these, because otherwise these smart low-income kids are wasting their potential. And when kids apply to college they need a usable metric to be compared, which their “official” high-school transcripts are not, so otherwise admission is just upper-income or lottery.

An upside to over-lenient grading, at least students can half-ass “school” while they take these alternative classes that are actually teaching them.

Most of the information a pianist uses for fingering are the feeling of the hand and the sound of the piano while playing. This is not visible. Eyes are of little use for musicians. There are blind master pianists.
Americans may consider themselves rebels, but they aren't. They talk a lot of shit about rebellion and watering the tree of liberty with the blood of tyrants but still let corporations, police and government run roughshod all over them, and follow their party's propaganda line without question. A country with only two relevant political parties, more alike than not, and only one civil war in its history is not one rife with rebellion.
The argument for what makes it a bad precedent is that it means incumbent parties will use it to prosecute their opposition. If the best you can do is jail your opponents to keep them from running, that's not representation, it's just a war for control of a weapon. I think he will gain unexpected support from some principled moderates as a result.

There is a streak of nihilism in the tactics used against this former president, and it has become an attrition game where winning means being the last one disqualified for cheating or the only one left not in jail. As though they think it's only organized crime when you lose. Comedian Duncan Trussel quipped the other day that politics has become, "an Olympics for narcisistic sociopaths," and that's a pretty good characterization. I'm not American and I can't say I'm neutral, but I do think that the malice this indictment demonstrates is weakness, and that's a fundamentally un-american sentiment that will repel a lot of reasonable people. I have acquaintences who will treat it as a betrayal, but what I believe is that Americans are better than this. Poignant that we live in a time where that could be so unforgivable.
I wonder how well this performs over standard GPT-4 with domain knowledge injected in as prompt.
When it comes to Trump, people seem to be blind to the effects of soft power.
Trump is beloved by his base in a way no other president in the last 100 years is.

The danger of this half-assed prosecution to the republic is fucking enormous, I'm actually scared.
By selecting the Ubuntu drive I installed linux in the Bios and then that would let me boot either windows or Ubuntu. Which is what it's supposed to do.
Yeah, hard for me to wrap my head around why you would throw high speed digital circuitry, DSPs, and complex algorithms into a box to try and emulate the sound that a simple heated cathode in an evacuated glass tube can produce. $24 can still get you a decent 12AX7, I believe.
As a musician, guitar tube amplifiers sound better and my ear (mind) will never be changed.
please guys, it's urgent.
If you go to public school in SF, you are probably poor. Well, the powers that be have decided that you’re too poor to be taught algebra so early. Probably because they don’t expect you to go to university. We need tradespeople and you have been selected for the role.
You prevent it by not electing someone so obviously unfit for office. Failing that, you discourage it by not giving him reason to believe that he's untouchable. (Sadly, his ragtag army of goons had to learn the hard way.)
I cannot see my Mac's case when I am sitting at my desk, and I'm not using an Apple keyboard. They make more than just laptops.
I've gotten the same impression. So many Windows tools are given away for free, no hint of ever monetizing or anything, just a hobby / service by the developer, and yet no code is provided.

I remember hearing an explanation from one such solo developer with a relatively recognizable brand that he doesn't want people to be able to easily replicate his tools with added malware / adware. But I feel like download sites have been doing that for years anyway.

He has released at least one tiny but useful piece of code as public domain.

Also he does have one product that charges for. I suppose one potential reason to keep code private is to maintain more control of the free tools for purposes of branding and bringing attention to the pay tool? That's just a thought.
But how far can the power go before wire resistance causes too much Vdrop? Maybe one good transformer+rectifier per room? AC to the room and DC in the room. Those DC runs would be <5m each.
The embeddings on their own are insufficient for this. You need some kind of sequential model to generate the code.

It should be possible to build your own model to do this instead of GPT-4 if you are so inclined. I don't know how the quality would compare but there are various specialized code-specific models already around (and more coming) that work quite well.
With all this GPT hype, it's good to see some good old fashioned hardware making the top page of HN.
I don't think so. I was a Python dev for years, and plenty of other languages don't have the issues Python does. It was a great learning language when I started, but I think most folks that have only used Python just don't realize what they are missing.
What do they call themselves in cali these days? Progressives I guess, good job.
Get a good teacher.
I redid a lot of their original "Foreplay" preamps for the aforementioned audio shop -- they were available as a kit option and a lot of guys butchered the assembly, apparently. Back then, the power transformer was the cheapest combo plate/filament transformer from Antique Electronic Supply, but spraypainted black. That particular transformer was being loaded at like twice its filament current rating! Little stuff like that really bothered me.
Well, my amp is not in any of emulators so I have my excuse. But I kinda like single purpose of dedicated amplifier

Because Trump has nearly religious following that scares many many people on the left and right.

They will do ANYTHING to stop him out of fear, anger, arrogance etc.
The problem here is Trump is an expert at reflection.
This HAS ALREADY empowered his base, and strengthened Ron Desantis.

> ...but I'm continually surprised that people ignore what seems to me like the worst realistic danger of AI. That is the use of AI by militaries, law enforcement, and intelligence agencies.

The "worst realistic danger of AI" is its potential to permanently destroy the economic power of a large fraction of the population. There's no going on to do "higher level" creative work after getting automated out of a job, since those jobs are going to get killed by AI too.

Increase standards, but also streamline processes. Leverage ChatGPT so students learn by repetition in innovative games with cool interfaces, virtual and 3d and sound/motion interfaces, with lots of gym time. No more identity bullshit besides what is basic to become a good person like it was common to be taught throughout the world like 10 years ago. You know what, fuck this. Pause everything. REWIND.

HARD FUCKING FORK on this reality. This is bullshit, I'm rewinding the time.

The problem is that there is absolutely no policy that could be implemented that would bring black students to the performance levels of Asian students. So they have to stop letting the Asian students perform.

"American IQ Test Scores Show Recent Declines, According To New Study" [1]

>American IQ test scores have dropped during a recent 13-year period, a remarkable finding that runs counter to the well-established trend of increasing IQ scores throughout much of the 20th century.

>The study found evidence of a reverse “Flynn effect” in a large U.S. sample of almost 400,000 individuals tested between 2006 and 2018 in several ability areas. The Flynn effect refers to the well-replicated finding that IQ scores increased consistently through much of the 20th century, with increases ranging from three to five IQ points per decade.

Lately I've seen 'Open Source' thrown around a lot in the AI space with little regard to if the thing in question is actually using an OSI license.
I was also annoyed for the opposite reason. I had assumed until then that math was more about application of what’s been proven rather than revisiting the proofs. I think the majority of students feel what I felt; that math got a lot less applied and a lot more esoteric in the academia.
Edcor are made in the U.S., Hammond ... in Canada? Both excellent transformers - and probably the most expensive part of the build (the tubes I use go for much less than the iron).
IMO, good math ed is balanced:

- Enrichment, visual, and speedy stuff to build intuition

- Proofy stuff to build rigor and reasoning ability

- Rote stuff to build arithmetic and symbolic manipulation skills

Ideally, it would be balanced this way from kindergarten to mid-undergrad. In practice, most students rotate through these.
In terms of tearing the country apart…I think you need to separate the nut jobs who idolize Trump from the right leaning folks who simply supported Trump mainly because he was on their side of the line and frankly not an elderly democrat who was a punchline before he became “The Alternative”.

The nut jobs will create problems, the others will complain but not act. Overall the others far outweigh the nut jobs.
