Let's look at the numbers. The energy to split one mole of CH4 (i.e. 16 grams) into C and 2H2 is 74.6 kJ. If you burn that carbon you get 393.5 kJ and if you burn the hydrogen you get 483.6 kJ [1].

> And the energy content of the hydrogen output is less than the methane input plus the heat dumped in. This is thermodynamics.

You are right, but you forgot something. You are not creating the methane. You are extracting it from the ground. The energy content of the hydrogen is only 60% of the energy content of the methane you use to get it, and if you account for the energy to split the CH4, you are left with only 50% of the original energy of the methane. But then you get hydrogen that can generate emissions-free electricity. It's a good trade off.

>The strain comes from context switching. From 9:00 AM to 5:00 PM, I had to care deeply about our quarterly goals and production stability. Then, from 6:00 PM to midnight, I had to care about inverting binary trees and system architecture design.

>This duality is exhausting. It forces you to lie by omission to people you respect. You can't tell your team, "I can't take that ticket because I need to study dynamic programming." You just have to work faster.

Almost seems like the interview theater is intentional, as a way to discourage job hopping.

They didn't, and you're again repeating misinformation as fact.

What happened was that they refused to turn access on for the Crimean region, which is not the same as "cutting off Ukrainian access".

I understand nuance is hard to grasp sometimes, but if you're going to continue to conflate the two things, I can only chalk it up to a desire to deceive.

I really don't feel it's that unique that it took a while to quit. A big reason these cultures are so popular is because a lot of of the time people don't quit right away and you can keep extracting work above their pay grade until they do. Even if you have some churn, you can keep getting that kind of work for cheap as long as you have a good supply of new hires.

How much of a problem is this for people that don’t store their gasoline in open containers?

Like, I get that many containers aren’t 100% sealed to avoid bursting/collapsing, but I don’t get any whiffs of gas when walking by my plastic Jerry cans.

Another potentially interesting project is zigx, an X11 client library for Zig applications:

Compared to libX11, it avoids dynamic dependencies, uses less memory, and provides better error messages.

Am I missing something? The suggested protection helps with XSS flavors of CSRF but not crafted payloads that come from scripts which have freedom to fake all headers. At that point you also need an oauth/jwt type cookie passed over a private channel (TLS) to trust the input. Which is true for any sane web app, but still…

The last time I tested, I could swear they were doing some problematic quantization, because I was getting kind of random results with one or two models, which worked perfectly when I switched providers.

It was really disappointing too because Cerebras does not provide any service reliability on their cheap plans. So I came to the conclusion that unless I could convince the client to set up an enterprise contract or something, we could not use either provider for low-latency, which we need for voice calls. I think for organizations that can afford a hefty contract that guarantees service levels, Groq and Cerebras especially are basically cheat codes for meeting latency requirements for voice. But that might not be an option for really small businesses.. although maybe I am just not a good sales person.

I imagine 2 big giants basically (Nvidia/google/amd basically influenced by a few select of people) vs (Chinese companies who have investments from the govt)

its sort of like proxy wars and this is sort of whats happening in software side of things with open source models but I think that the benefit of the proxy wars is going to be for the end consumers

But although on the other hand, having two large countries compete with each other while buying everything else and all feels like it astronomically increases the price if someone wants to compete with these two giants (any other country perhaps)

We definitely need a better system where it doesn't feel like we are seeing pacman eat everything up basically

> I want to express meaning and connotation with tones, rather than denotation. On the other hand I've never been terribly motivated to learn a tonal language, so it probably could be overcome, but it's something that would take an immense amount of training to overwrite that tone=connotation/emotion/question instinct.

Why would you want to? Pitch also provides connotations / emotions in Mandarin.

> It is also quite frustrating when a native speaker is completely unable to understand something you say because of a tonal issue.

That will never happen. Your bad pronunciation can aggravate other problems, but if your sentence is otherwise good, ignoring the tones will still leave it fully intelligible.

(I once asked a student in a Chinese school whether a particular class wasn't occurring, and he responded "poss". After some confusion, he was frustrated that the pronunciation difference between "poss" and "pause" should make such a difference in communicating with an English speaker.

But of course, it doesn't. If "pause" were a valid way to respond to "is chemistry class happening today", I would have had no difficulty understanding "poss". His problem was in bad knowledge of the language, not bad pronunciation.

You appear to be making the same mistake here. If you try to communicate, and fail, that is not evidence that you are qualified to diagnose what the problem was.)

Honestly cerebras is good. I can recommend it. I talked to their team once on discord as a literal free user so that was something really nice personally

They were also the faster one compared to groq but they were always a little slow on adding new models compared to groq but not sure what changed right now.

Definitely recommend cerebras tho now that groq's been eaten up from inside basically

It’s worth noting here that premature deaths were routine back when these decisions were made, in a way that we would find almost unimaginable.

While smallpox was no longer a major threat, influenza, polio, whooping cough and a bunch of other infectious diseases killed kids in huge numbers. People died from infections from routine cuts. Millions of young men (mostly) had been thrown in the meat grinder of WWI.

Life was cheaper then.

I thought ethanol was cheaper than gas. And the octane boost means the gas doesn’t need as pricy refining, especially in summer when you can’t load it up with butane.

+ the decreased fuel economy gets people to the stations more often where the high margin stuff is sold.

And if the US can convince the world to include ethanol in fuel, that helps if you’re the biggest corn grower on the planet. Even Canada imports about half of its ethanol (almost entirely from USA), with some of the domestic ethanol production using US corn.

BS, windows and macos cant even do proper window managing for a start, and then it just goes downwards from there on.. You can perhaps install various weird third party things, but it does not come with it by default.

If you took people who absolutely never tried any computing, and gave them macos, windows, and for example Plasma, they would NOT consider windows or macos to be ready for the desktop. If you go 15 years back, even way more so.

even in the early 2000s, windows was so hilariously crappy that you had to make floppy disks to even get to install the thing. If PCs didnt come preloaded with windows, regular users would never ever be able to install it, versus the relative ease a typical linux distribution was to install. This is also one of the large reasons that when their windows slowed down due to being a piece of shit with 1000000 toolbars, people threw it out and bought a new, despite the fact that a reinstall would have solved it.

> Take the bits you want (money, skills)

That’s exactly what the author did, and it’s why the leveling piece matters so much.

At big tech companies levels very directly control comp, and less directly control the scope of problems you’re trusted with.

You absolutely can tackle large, high-impact problems as a more junior IC, but it usually means pushing a lot harder to hold onto ownership. Otherwise it’s REAL easy for a more senior IC to step in and quietly take it over.

> Is App Engine still preferable purely for cost predictability?

How is Cloud Run cost not predictable?

It is fairly simple arithmetic in a spreadsheet to estimate the upper bound with # of max instance times the unit prices times the per-instance resources. Exactly the same as you do with App Engine standard & flexible environment.

> budget caps

Doesn’t exist in GCP and most cloud providers. You can fix the usage or hard cap the usage autoscaling, but not the spend incurred by the usage.

> What guardrails work that don’t depend on constant manual billing checks?

Start conservatively with max instances and instance resource, and iterate based on the actual performance and needs.

Do your capacity planning and cost estimation and understand them. “Solo dev” or not, you need these things to run the business. The root cause was that you outsourced your business and budgeting decision to LLM without verifying it and understanding it.

To you edit: Again, you are ignoring the issue I raised: Whitewashing nazi issues(not the casual nazi labels we have seen these days, but the actual Nazi Germany) would be considered far right.

This is about the actual fact about whitewashing the actual historical Nazi Germany. So I would take it as you are dodging the question and you are agreeing with my previous criteria:

The people or organization whitewashing the actual historical Nazi Germany issues would be considered as far right.

> to handicap an inference company

That's a non-charitable interpretation of what happened. The are not "spending $20 billion to handicap Groq". They are handing Groq $20 billion to do whatever they want with it. Groq can take this money and build more chips, do more R&D, hire more people. $20 billion is truly a lot of money. It's quite hard to "handicap" someone by giving them $20 billion.

I've been at three FAANGs now and my experience has been that nobody really cares about your level for day-to-day work. The only times it has ever come up for me is when a) I was part of assembling a new team and we needed a mix of juniors and seniors or b) when some dangerous action like deploying during a holiday code freeze needed approval from an L9+ by policy, so you had to go find that person and justify it to them.

Now, your compensation is based entirely on your level, which obviously makes it matter a great deal, but my experience hasn't been that there are mind games around it.

Please make the zip files availible for all three dataset 8's!

The number of files on voidzilla's video is different than the number availible from all three on jmail.

There is no meaningful way in jmail for me to contrast the files to see what has been removed or added.

There is also no way to download all of them.

While I appreciate what you have made, it isnt useful for what I want to do, which is contrast the three versions of dataset 8.

It would be easier if you just made the zip files availible.

No shade to jmail, its a neat tool that tons of people find useful, myself included, just not me in this one scenario.

I’m whatever the opposite is of a devoted fan of Newsom, but I think describing the cause of this aggregate mess as PG&E buying politicians is well off the mark.

The problem is that PG&E is just one player in a system built up over decades. The system is built on the wrong set of premises, continues to evolve based on those premises, and can only be fixed by rejecting those premises.

This is becoming increasingly obvious, and a politician like Newsom is too smart to tie himself to the mast of a sinking ship.

Reality is that different resources have different impacts on an eng. org. Some individuals are eng. orgs onto themselves and can own a whole stack (breadth). Some are very specialized in areas that require deep expertise or experience (depth). Some are good engineers, but lack both breadth and depth of knowledge. Leveling let's you delineate comp bands accordingly.

I got recommended this and I will watch it today, thank you. One of the comments points out

"They’ve literally told us that the plan is to get bailed out by the taxpayers"

This reminded me of how I think what's gonna happen/ is already happening is that they become too big to fail and get bailed out and the burden/loss becomes of taxpayers

So we are kind of living in a system which is reckless about finances/stability behind businesses where the system is such that all the profits are privatized but all the losses are shared/even funded by the average person

Combine in a mix of corruption in any political party to begin with and I am wondering why we don't have yet another french revolution.

> this job search is the hardest I have faced in over 30 years. Just talking to a human is almost impossible.

My advice: Don't apply on platforms that are filled with spam. I think the best choice I've made for work is posting on Hacker News that I'm looking for work rather than bothering with job sites like LinkedIn. Both times I've done this, this last time even after being laid off, I had a new position within the month. I've never even gotten replies on any other platform: not on LinkedIn, not on Indeed, not on Upwork... but commenting on Hacker News has gotten me a job in relatively short order, every time.

My personal hypothesis is that employers look here to find interesting people... or at least that's how I'd go about it. Both companies I've joined from HN have been filled with obviously autistic people.

Well, you can. But if you're just learning the language, you're going to struggle to find words that don't use a predictable one. And if you do stumble across one of those, and you use 个 instead, people may not even notice.

If an attacker has a user's private authentication token, usually stored in a __Host prefixed cookie, then it's game over anyway. CSRF is about protecting other sites forcing a user to make a request to a site they're authenticated to, when the malicious doesn't actually have the cookie/token.

CSRF is when you don't have the authentication token, but can force a user to make a request of your choosing that includes it.

if we go back 450 million years ago we'd find giant fungi the size of large buildings.

i can't believe this paper didn't cover mycotronics.

also it fails to mention that mushrooms are natures chemists, given sufficient time the can be trained or bio-hacked to breakdown & digest almost anything. the 5th kingdom they are not plants! they emit co2 and consume oxygen.

myco-chitin is a ridiculously interesting in terms of it's tensile strength to weight ratio outperforming virtually all composites including kevlar. the chitin material is a dilectric and can be impregnated with wire strands or other conductive metals to make very interesting unparalleled e-fabrics out of myco-leather.

the "gap" is that mushrooms aren't farmed for aerospace applications, and most of what you find at a farmers market will be either small batch cultivated or more commonly discovered by humans (probably hippies) who spend time wandering through a large forest.

the reality is mushrooms are renewable resources, they can at scale compete effectively with cellulose, and everything you know about useful cellulose -- mushrooms are at least 100x better, but it's easier to cut down a tree than grow a mushroom the size of one.

also the mushrooms require a complex fabrication system and most of the processes we see today are proof of concept, very manual, lacking sufficient automation to compete with plastic & cellulose (so they appeal mostly for novelty, not value).

yes - i've got my own applications in development. no, i won't tell you.

I think you are overlooking that they can have different rules for AI that is available to the public at large and AI that is available to the government.

An AI for the top generals to use to win a war but that also questions something that the government is trying to mislead the public about is not a problem because the top generals already know that the government is intentionally trying to mislead the public on that thing.

Looks like Unity code. Not sure if it’s Visual Studio or VS Code, but yeah, it was baffling to me how weirdly bad C# support in either IDE is. Maybe something wrong with my setup, but autocompletions indeed suck (in addition to just wrong picks, editors often would suggest a symbol that doesn’t make sense from the typing perspective, as if there aren’t any language servers or intellisense or whatever).

VS code would also eat up the curly brace at the end of a class declaration when auto-generating a method skeleton.

I gave up and installed Rider. So far so good.

I agree there is certainly more than one factor and no place has 100% of them perfect, but that doesn't make an individual factor any less stifling - just perhaps it's outweighed by good approach in other factors.

Maybe the thing that might equal this out most is the US and EU seem to be equally as interested in censoring and limiting models, just not for Tiananmen Square, and the technology does not care why you do it in terms of impact to performance.

Ya I suppose that is a fair point, albeit a tangential somewhat luck-based one. Additionally, that ceiling has been likely raised across technical professions for non-men as well who have the potential and drive to be at the top of whatever ladder. I say tangential because while the ceiling was raised significantly, the parent's argument was that it wasn't nearly as necessary to be the 1% fortunate genius landing a dream gig, which is still true.

"you can only work on one thing at a time. It should always be the highest priority item"

The thing you're working on in any given moment is the highest priority thing (in "your" mind) by definition though. If you thought something else was higher priority, you would be doing it instead.

The only "argument" against that requires a third party who deems a different thing higher priority than what you're currently working on, and that leading to a mismatch of what is "highest" priority is, and you're lack of doing it in the moment.

> Knowing my luck I'd also run into OLED burn-in the moment the warranty expires.

Not being aware of the author's history of luck, that's an extraordinary claim. OLED screens are commonplace in modern devices -- phones, tablets, laptops and desktop monitors etc. If burn-in is still a real and significant concern, manufacturers would not have released so many devices, often with OLED screen as the only option. You would see videos on YouTube and TikTok warning you about OLED screens everywhere.

If anything, battery life is a bigger issue.

I really wish the author had done more research before making the decision or writing this piece.
