Nowhere in either this article or the paper is an estimate given for cost, nonetheless an analysis justifying the estimate.

Desalination has a fundamental energy cost, and solar energy is fundamentally limited by what is received. The real question is whether it is cheaper to set up a solar-thermal desalinator, or set up solar panels that can power more efficient desalination methods.

Solar panels are cheap and getting cheaper quickly as there is an incredible economy of scale. While desalination systems could likewise be mass produced, there will never be as large a demand for that one specific application of solar power as for general solar power. Further, photovoltaics are reasonably simple solid state devices which are well suited to mass production. I am highly skeptical a priori that a solar thermal system could compete on economic terms. Perhaps in a space confined situation it makes sense, but it's tough to run out of space in the ocean.
> Do you want to never let a perp go (i.e. jail innocent people in order to catch every guilty person) versus let some baddies slip through the net while not imprisoning innocent people

Isn't the latter the official standard most places? Innocent until proven guilty. It's just not really a dilemma if you ask me. If you have authority to do something based on some event, then you have to prove that event happened.
Or I am wrong?

It’s a front end for propaganda and publishes anonymously.
The article literally states:
> the people we brought in were working such grueling hours that eventually the money wasn’t worth it to them and we’d lose them.

So the author wants to find workers that somehow look past this risk/reward imbalance and determined that Ivy grads are not it.
Not quite. ChatGPT incorrectly mixes up SI and non-SI units.
>> Why not live closer to your pals?

Oh well easy. In a city like Berlin, because even if you are a high income professional the housing market is so Fubar that you cannot decide where you end up living in the city. You take what comes your way and be done with it.
This is true for most other big cities in the world.
I guess the answer is don’t live in cities?
So like crypto and web 3;)
But you're not comparing the same thing, Go handle errors and act on it, Rust code just "forward" the error.

Control flow wise, Go is much easier to understand than chains of ? and await.
Oh, that means its a llama architecture model!

Is the tokenizer the same? It may "work" without actually working optimally until llama.cpp patches it in.

And the instruct model was just uploaded.
Yeah, an X270 is my newest Thinkpad. I got it as kind of a beater for a vacation that COVID cancelled. That or an X280 feel like kind of the sweet spot for usable almost modern small Thinkpads that can still be upgraded. USB-C port for charging, video out, etc. $70 FHD display panel. Can take two SSDs (one small one in the WWAN slot). It's been mostly fast enough for everything except heavier games but software builds can be slow.
> How many refactorings per time unit could a smart coder do in both ecosystems?

I've found that refactors are more involved in Rust (because of some "viral" features that require changing code in a lot of places, adding lifetimes to a type being the most obvious example) requiring more effort from the developer, but that after handling the complaints from the compiler the resulting code is usually properly ported to the new design. This has not been my experience in other languages, particularly dynamically typed ones. It is partially helped by some design patterns that are prevalent in Rust libraries, like typed builders or more complex trait bounds that ensure correct usage of the exposed APIs.
This is just not true.

You are no more and no less locked into MacOS than you are under Windows or under Linux.

I'm not sympathetic to them, but there definitely ARE substantive arguments a FOSS devotee could make about MacOS that make sense, or which are at least grounded in fact. This is not one of them.

They bought it while fully aware of those shortcomings. It’s like people buying cheap land next to an airport, building a house, complaining about the aircraft noise.

Do not buy it.

I am.
The way it works with cloud providers is - you can file for a refund for SLA breach. After all - those SLA's are at a service level for the customer. If you're yelling at support or engineering on the phone, you're likely getting the 9's treatment the author describes - this is the wrong forum to hold the provider accountable unless you're yelling about mitigation time (then, best of luck to you!).

Reading the fine print on the SLA's is extremely important, because they often do not say what you think they say.

I have seen refunds on the order of hundreds of thousands of dollars. It's cold comfort if the impact to you was on the order of millions of dollars, but still it is something. As you can see it's not a free-money-a-thon, it's generally a % of your spend of the services which were not available.

There typically is a defined process for submitting a refund ticket, which will result in an availability review. This documented process is not always easy to find.

The only one I could easily find is for Microsoft:

(It's just a support topic when you're submitting a support ticket)
> * Results show up in the phone app in < 24 hours. (Machine modem -> cell network -> provider -> app instead of machine -> app, which I think explains the delay)

This seems like a huge downside. What data is being collected? Who else gets access to this data? What will these third parties use it for? How is it secured?
Ethically, IMHO, if you owe monies to third parties for undisputed work done, you should pay that.

But as said in another response, hire a (not-too-fancy) lawyer or a company liqudator to constrain how messy this may get.

Going by how my Macbook's battery life evaporates with 10 Chrome tabs + Slack + Zoom, I believe it. Gaming is definitely less load than multiple windows of modern work apps.

> Pretty much every time I talk to random people in the US, they drop inflammatory remarks to see how I respond, to identify which side of the culture war I am on, so they can antagonize or befriend me. I ignore these comments, as I am disinterested in the American culture war and its political sports-teamism.

Weird. Everyone in my neighborhood avoids politics like the plague.

I think my favorite part about where I live is my neighbors. The thing we have most in common with is our community, kids, and the troubles that come with home ownership.

We invite eachother over for pool parties and BBQs. My neighbor, who I'm pretty sure is exactly the opposite of me politics-wise (I've heard him talking in the backyard before), nevertheless invites everyone over for labor day and 4th of July. We talk house and neighborhood problems. His kids are only slightly younger than me but we still talk kid stuff.

Another neighbor is on a fire safety council (a non-profit) and helps deal with some of the issues with that, and I've helped them with tech stuff before. You wouldn't think it, but he's kinda a nerd himself. This is a 60 year old retired firefighter with a garage full of motorcycles who could probably bench press me but his house is full of legos and star wars stuff.

In general, people are very happy to help with problems and cordial. We have a text message thread with about 15 houses on it.
I agree, plateauing may be more apt in this case. I wonder to what extent exemplary questions like these remain universal, or have an expiry date that just isn't known at this time.

There's no such thing as a "have-debugged-and-contributed-actual-code-to-fix-it:" tag. He didn't write the actual commit that fixed the issue, so he was credited in the commit message instead. That seems fine to me. The fact that they didn't include an entire paragraph detailing the exact nature of his contribution isn't a reason to blow this up into some big community drama with over 500 comments on Hacker News.
++ agreed.

ClickHouse Keeper was released as feature complete in December of 2021.

It runs thousands of clusters, daily, both in CSP hosted offerings (including our own ClickHouse Cloud) and at customers running the OSS release.

Never accept any claims at face value and always test. But, in this case, it is quite battle-hardened (i.e. the Jepsen tests run 3x daily https://github.com/ClickHouse/ClickHouse/tree/master/tests/j...).
Thermodynamics can't be cheated. If you want to turn some liquid into gas at given pressure you need to deliver specific amount of energy regardless of how you do it.
This seems like on paper it is quite close to the Apple Vision Pro. The performance per watt of the chips is probably not far off and both devices deal with the same basic design constraints of needing to fit comfortably on your head. The main difference seems to be the micro OLED and eye tracking on the Vision Pro vs. the Quest’s inclusion of controllers.

I’ll be curious how these two devices stack up to each other and exactly how different the user experiences end up being. The MR experience seems like it may be close. The VR gaming experience seems more emphasized on the Quest, but hand tracking has come a long way so I wouldn’t rule out the Vision Pro here either.

Overall I’m doubtful either device will hit mass market appeal.
"they might be different to me" is not the same as "they will be actively hostile to me when they learn more about how different I am".

In the US I find conformity to be widely regarded as desirable, and being "weird" to be seen as a negative. I am weird. This lowers most normal people's opinions of me.
Have you compared the plot of every single block buster superhero origin story?

The standard “heroes chase after the MacGuffin device” story?

They are called “tropes” for a reason. If you know the tropes you can pick them out very easily from almost any movie.

Every transformers movie plot is basically the same as is every James Bond movie and Mission Impossible movie play to same story.
Compared to playing a game which would definitely use both GPU and CPU, instead of mostly just CPU?
Cloudflare has almost no cold boot and I think their ml models are prefetched within the same DC, so loading the model the first time should have no noticable overhead either.

Correct me if I'm wrong, but that's how I interpreted it when they first started with ML models on their CPU's.
Why do they need to write requirements? That’s primarily an engineering function. An engineer should know how to translate the user/business need into a technical requirement.

Let the business and ops people focus on what they’re good at.
Interesting that in general, such personal accident insurance isn't widespread today.

Instead, people hope to find someone to sue - for example, suing mcdonalds for hot coffee.

However, if I have my arm eaten off by a crocodile tomorrow and I can no longer do my job, I wouldn't be covered by anything. Can't sue a crocodile.
I've interviewed hundreds of college students and recent grads and have never had this happen or even thought of it as a possibility. I can't imagine how I'd respond as it feels so far out of norms I'd expect.
I would say it's for the sake of safety. Children may be the topic here, but it applies much more widely to safety in general.
>I cannot wait to ask it how to make nuclear weapons, psychedelic drugs

This is an interesting idea. For the stubborn and vocal minority of people that insist that LLMs have knowledge and will replace search engines, no amount of evidence or explanation seems to put a dent in their confidence in the future of the software. If people start following chemistry advice from LLMs and consume whatever chemicals they create, the ensuing news coverage about explosions and poisonings might convince people that if they want to make drugs they should just buy/pirate any of Otto Snow’s several books.
Mechanicisms matter. The article talked about plastic HEATING allowing it to leach into food that it’s TOUCHING. If you’re lids are not heating or touching food, maybe it’s fine?

Counter example could be condensation on lid heating,leaching, then dripping on food.
I wonder if that's AR, and the cameras/processing involved are what use more power.
Also, there are many low-stakes situations where AI is actually quite a bit better than the average human:

1. Take a photo of a piece of tech: AI can not only describe what's going on but tell you exactly how to fix it (e.g. "it's showing a fatal error. hold down the power button for 10 seconds to reboot it")
2. Take a photo of clothing: AI uses consistent, neutral language to describe garments, while humans would all describe the same item differently based on where they live, their own personal style, their region, etc.
3. Take a photo in a major city or near a famous landmark, AI will recognize it and tell you about your location, whereas a random human has probably never been there before
4. Take a photo of an insurance bill, AI can explain what some of the technical terms mean if you don't understand them
5. Take a photo of a menu, ask it to summarize all of the vegetarian entrees and it will list them in seconds ("one veggie burger, one stir fry with tofu, three sandwiches and all of the salads"); a human might take a minute or two to carefully read the menu and give a much longer answer
The ability to torpedo your entire business by signing the wrong requirement is unparallelled for this reason. Indeed, it's often used maliciously.

Here. Pour a drink. Let me tell you a story.

UltraWag, a supplier, signs a contract from MegaWing, a big aircraft OEM, for 2000 UltraWag SuperRadio units at 12k per unit. Under the contract deliverables, MegaWing gets all UltraWing tech data in this specific BIN format. UltraWag business development signs up for this 24M contract, thinking, "we can make BIN all day long, no problem".

Yeah, they should have asked someone with a technical degree.

The UltraWag dev group dips its toe into the BIN spec, and sees that it's impenetrable. They get on the horn with the reps at MegaWing.

MegaWing says, oh, yeah, of _course_ you need help with getting MegaBIN spooled up. Let's get you set up with the MegaWing MegaBIN SDK, the MegaWing MegaBIN IDE, and the MegaWing MegaBIN build tool. That's 1.8M worth of software, so discount the SuperRadio unit cost by a thousand bucks or so. UltraWag signs off, and on they go.

Now, this doesn't solve a lot of the problem. The MegaWing SDK needs configuration, the build system only works for OS2/Warp. MegaWing sends some experts down to UltraWag, 5 consultants at 100/hr for two weeks. That's 40k, another hundred bucks off the unit price. This happens again, with an SDK change and an IDE change.

And now, we've got a problem.

The problem here is that the SuperRadio 12k unit cost has a margin of 12%, or $1440. The initial MegaWing software discount already took a huge chunk out of that, and after a very few consultations the SuperRadio is now getting sold at a loss. UltraWag owes MegaWing money for giving them product.

UltraWag might confront MegaWing about this, to which MegaWing might respond[1], "Sure, but now you have 𝐌𝐞𝐠𝐚𝐖𝐢𝐧𝐠'𝐬 𝐈𝐧𝐝𝐮𝐬𝐭𝐫𝐲-𝐋𝐞𝐚𝐝𝐢𝐧𝐠 𝐌𝐞𝐠𝐚𝐁𝐈𝐍 𝐒𝐨𝐟𝐭𝐰𝐚𝐫𝐞 to use as you please!"

Sure, you have these new tools . . with the MegaWing SDK, the MegaWing IDE, the MegaWing build, the MegaWing everything. It can't be used for anything else. In effect, MegaWing just paid for a product with dollars that can only be spent with MegaWing. This is not a transaction. It's colonialism.

Ok, good point. Perhaps the role of each pad can be annotated in the symbol libraries. Or perhaps we can use LLM technology to read the datasheets and figure out the role of each net ;)
I'm a bit out of the game on VR these days but I noticed there is no eye tracking which probably means no foveated rendering? I thought that was the new hottness these days.
Standalone, but you can connect to PC if you want to play graphically intensive games. Quest 2 basically, you login with FB account so you need internet connection at first. Pretty "unhackable" afaik, you can install custom mods for games but thats pretty much it in terms of modifications I've seen.

I wouldn't mind having access to codeine because it is a very effective painkiller compared to OTC stuff in the US. I also don't mind not having access because I find the addictive potential of opioids personally threatening.

None of that matters to heroin users or users of more powerful prescription opioids because codeine will not give them the high they want. A better model would be something along the lines of marijuana dispensaries or state-run liquor stores, where legal sales can be made but with added levels of difficulty/obscurity. That kind of rigid legalization scheme probably wouldn't kill the black market, but it would absolutely save lives. Many people who are dead today would still be alive if they could have simply purchased a safe version of the drug they were going to do either way.

I agree that Go's web backend features make it fun to prototype an application. But the moment I want to do anything more complicated, then I'm not sure.

I counted the number of lines in my work projects, and I have $WORK projects that are 100k lines of code. Maintaining that in Go would seem like a nightmare to me, but in Rust that is so much nicer. My personal projects range from 10k - 35k and in all of those I much prefer the ones where I'm writing and maintaining Rust vs Go when it comes to similar complexity.
you can do both! all of our models are supported either via workers / pages binding (which makes it really easy to host the rest of the logic), and via REST API

Most company types will have concrete details for defining ownership proportions (controlling interest) and/or assigned roles with broad but clear allocations of responsibility and authority. Hopefully you have similar contracts defining the rules of engagement with your angel investors.

If you're worried about litigation and liability, fall back on what the concrete legal docs say you can do.

If not done yet, step one should probably be updating the company docs to reflect the reality of the founder separation. This of course requires negotiation of an agreement with your cofounder unless you set things up where you have controlling interest already or want to outsource it to a lawyer.

If you clarify the region, company type, and whether the separation was formalized, then folks might be able to provide more specific advice.
We probably aren't there because of consumer demand. None of the headsets have really gotten enough sales to justify the research in those things to make them better. If they were selling like smartphones we would have a much different set of features.
