To a first approximation, a good gaming build will be a good AI build.

I just built a new machine with an Ryzen 9 7950X, liquid cooling, 40-series graphics card. It has all that RGB bling... I mean, I might have been able to get parts that don't have the bling but there is a supply chain crisis going on, the DDR 5 sticks I can find all have RGB, the liquid cooling system has RGB, as garish as it is, it is what is.

It seems to me that you have fewer practical choices building a machine today than before. There are only 3 expansion slots on my motherboard, the GFX card covers one of them, there is no sense in putting in a sound card when you are using an SPIDF digital out. There is not a lot of room in the case for optical drives, large hard drives, that kind of stuff. I have one spare USB 2 header, mostly I depend on the I/O on the back. The one thing I might put in the open expansion slot is a Thunderbolt 4 card but I'm not sure I really need it.
Don’t say “It’s usually better”
If its more than one engineer I would say there is a very real chance that the issue is the manager.

Sometimes things need to be more complex than they first appear. Think all that pesky error checking that you totally don't need as long as everything is working perfectly for an extreme case.

If the engineers are experienced think strongly about letting the do the work as long as they are ones who will also take the pain of the complexity. Also having them explain why something is needed to the rest of the team is a good way to have everyone on board with a decision and it helps bring the rest of the team up to speed.
SBF may have hit a ceiling of punishment. What are they going to do? Add another lifetime jail sentence? Another billion dollars he cannot possible repay?
>> teams can easily maintain up to 10 or even 15 (micro)services

Your arguments reject complexity, then, in the next breath, endorse it. Micro-services are the enterprise bloat of our time (and likely the worst example of all the bad ideas that have circulated in that space). Small departmental apps used by 15 people require 34 micro-services (all hitting the same db tables of course).
Sounds like Germany. At least this is exactly how it works in Germany.

And regarding your plan: Depends on the employer but yes it works. I had a colleague who didn't plan to do any big vacation so he just took a day of every friday for months.
Well geez wise guy, if he gave up the shirt on his back they wouldn't let him in the bank to give up all his savings.
Show HN: New Visualizations for Chess Enthusiasts
Hello HackerNews, I'm happy to share my newest analysis video of the recent Chess game between Magnus Carlsen and Nodirbek Abdusattorov in the World Blitz 2022

Link: https://www.youtube.com/watch?v=bMV0GY-Sicw

I had previously put out some videos in a similar style on the channel but wanted to see how far I can get the visualizations and how much I can automate it with python. The biggest time sink when creating these videos is adjusting the individual parts of the video using matplotlib, which I can mostly reuse across videos. Here is what I show in the video beside the chessboard:

The bottom visualization shows the engine evaluation across different depths, which allows you to (1) follow the engine evaluation of the game and (2) compare evaluations across depths to find surprising moves (which I originally implemented for this repo: https://github.com/CYHSM/chess-surprise-analysis).

The right lineplot indicates the number of games which have previously reached the highlighted position. This allows you to see when a completely new game starts (Thanks Agadmator) with steep drops indicating more exotic lines. The title in the plot also indicates the opening name, for as long as they are identified.

Please let me know what you think and if I should upload more videos in the same style.
Any link to the 15k machine ?. Maybe it is cheaper now.

Agreed.

If he just shut his mouth it would be difficult to judge his thoughts. However his-Adderall fueled posts betray him.

Doesn't look good when yet again here he expresses wishes to reboot the fraud. It's a pretty clear signal as soon as this guy gets out, if he is in fact a criminal, that he will do as he says.
This is just a guess but I'm sure somebody has analyzed this novel model you propose where they charge more for the streaming service but target it at older, richer viewers and decided it doesn't pencil out:

How many people are really tons richer as they get older? Not especially many, this is an upper middle class phenomenon.

Given this small audience, are those people willing to pay 20x more per month for a streaming service to make up for that? Probably not.

If they get young people hooked on this cheap content now, they can keep charging them for it for their whole lives. How many times have you bought /The Goonies/ or /Die Hard/? The copyright holders of /Euphoria/ hope to be doing the same thing in 40 years.

It's similar to consumer packaged goods (deodorant, laundry soap, etc.) where the lifetime value of a customer is loads better if you get them into your brand when they are young. Convincing a 65 year old to change brands of shaving cream is both expensive (they have high standards and preferences from decades of shaving) and has low return (they won't be buying shaving cream for much longer). Convincing a 15 year old to buy your brand of shaving cream is relatively easy (they don't have any habits around which brand to buy, and also not much experience/preference) and they will be buying it for decades to come, so it will be a big return if it works.
In many cars fog lights and high beams are mutually exclusive. You can't turn on both even if you wanted to.
This is really misleading as it ignores the main fraud FTX committed: commingling user funds. Exchanges should never put their users' assets at risk and FTX's T&C said they didn't. If you deposited 1 BTC on their exchange, they were supposed to store that 1 BTC for you.

If they had done that, there would be no issues. If users leave, you just give them back what they owned and no one loses money.
Corollary: Dave Ramsey's observation that Cash is King. It's less true now that commercial sellers (car dealers, big appliances, etc) often make money on selling you the financing, but few sellers will forego a sale just because they're not getting a commission on the financing.
My project had the same issue. I ended up stripping out AutoMapper and manually mapping my types. In the end, it was much easier to determine exactly what was going on, and now I have one less third-party dependency.
another deep cut of testing is maintaining them, especially the blur between improper old test with changing specs, you this squared map to fix now.
I'm all for protecting PTO but fining people seems unnecessarily punitive in all but the most egregious circumstances.

But hell yeah, take that time. For the last 15 years I've worked for a guy who maintains basically no work/life balance for HIMSELF but vigorously defends it for his employees. In exchange he has tremendous employee loyalty. Imagine that!
Here is a related tweet that touches on exactly this issue: https://twitter.com/sethrosen/status/1252291581320757249?lan...

> So it's 9 cycles vs what, one?

I'm not sure what you're asking? What are you trying to compare?
Honestly, I believe he really believes he did nothing wrong, and really feels bad about anyone getting financially ruined.

I think he was kind of an idiot, in an environment where lots of people were getting rich behaving in unethical and illegal ways, and getting away with it, while convincing themselves they weren't doing anything wrong. That whole "scene" created it's own version of reality in which they could do whatever they want and make up their own facts and deserved only victory... which sounds kind of familiar for the USA and much of the world in general these days.
Different developers have different values. It is clear in this case these “smart” devs have different values than you.
It sounds like they are engineering towards a view of “elegance” of the solution, what is the most compact and DRY way to accomplish a result. You appear to value simplicity over elegance, which makes sense in the brief context you’ve provided.

Convincing them to switch values may take a long time (or never), but in my experience you need to repeatedly stress the values you want the system built on, and give concrete examples of why whenever possible. Give practical reasons why simplicity is better (system stability, debugging, maintenance, etc).

But recognize that for some “smart” people this will be “boring”, and they will never do well. It reminds me of a manager I had ages ago who preferred C++ to Java because his C++ solutions required huge amounts of brain power for anyone to understand, where as the Java solutions could be understood even by dullards like me.
Ask HN: How can I find a German family by their crest?
I just inherited a ring that has been passed down in my family since WWI. My great grandfather (who was a scoundrel) took a brooch off of a dead German officer in 1915 in Belgium. He had it converted into a ring.

In 1931, my great grandfather coincidentally met the brother of the dead officer. The brother saw the ring and said, "That looks remarkably like a brooch that has been in my family in Bavaria for a long time."

I'm not actually sure if it's a crest, now that I write this. And it's pretty small. If possible, I'd love to figure out how to get it back to that family, but I have no idea where to begin.
selectivity is an English word. I usually hear it in the context of describing the bandwidth of a radio receiver system (how well the receiver can select signals of interest and reject others)
Yes, I use it in that way. And if ChatGPT didn't generated the code with pure functions (usually it didn't), you can explicitly ask to generate the code with pure functions. Then ask to generate the tests.

Usually I get good tests from ChatGPT when I approach it as an iterative process, requesting multiple improvements to the generated test based on what it gives to me. Note that it doesn't replace the skillsets you need to know to write good test coverage.

For example, you can ask to generate integration tests instead of unit tests in case it need context. Providing details on how the testing code should be generated really helps. Also, asking to refactoring the code in preparation to make it testeable, for example, or requesting to convert some functions to actual pure functions, or requesting to refactor a piece of code it generated to a separate function. Then you ask to generate tests for normal and also for boundary conditions. The more specific you get, the chance of getting a good and extensive tests from it is much higher.

Having the tests and code generated by ChatGPT really helps to catch the subtle bugs it usually generates on the generated code (fixing it manually), usually I get test coverage that proof the robustness I needed for production code.

This approach still needs manual fine tuning of the generated code, I think ChatGPT still struggle to get the context right
but in general, when it makes sense to use it, I'm more productive writing tests in this way than manually.

Because the labor to properly insulate a home can be quite extensive, while the labor to install a heating unit is typically less than half a day.

Take a structural brick house built with no cavity insulation, plaster walls, and a finished interior and try to get any amount of additional insulation into the walls. You end up having to destroy and repair the finished plaster walls, which is obviously prohibitive from a labor cost standpoint. Those projects can be (and usually are) done when remodeling/redecorating is already planned (so you don't double-pay for finish work), but are economically unrealistic to do just to save on HVAC.

I agree that a very large portion of these instances are likely "neurotypical wants neurodivergent to be neurotypical".

That's not necessary to achieve the desired goal, but more empathy and better communication is.
Just like bad/fragmented YAML libraries now, there were plenty of bad XML libraries and implementations. I didn't think XML was too bad until I had to write a SOAP request where the endpoint would throw an error if the arguments (in their own tags, mind you) weren't in a specific order. The endpoint gave me no hints.

Additionally we had to update WSDLs for these services, but the service generating the WSDL used features our server's SOAP library didn't support, so someone had to manually transform the XML and via lengthy trial and error to get it to work.
Vanity sizing means the items is listed as a smaller size than it truly is, changing the units doesn't change anything. They can still say its 28" when its really 30".
My reluctance in having an internet connected camera in my house 24/7 is why I bought a LIDAR vacuum. For similar reasons I had the security cameras removed from the house when I bought it. I've worked in IT long enough to know not to trust either the code or humans involved.
indeed, but the point was this malicious scripts usually try to install programs, like droppers.
Did you not see his two spreadsheets labelled "JUST AN ESTIMATE" that clearly show he is right? I would love to know the thought process behind his decision to make this post.
I think the difference is since you do this at scale it puts a lot more pressure on the grid. EV adoption is still quite low relative to the fleet.

Yes heat load and AC are drivers for california grid and similar climate grids.

I would wager that if the north east went electric heating and EV they would have significant problems in the winter. Grid reliability would be even more important given that transportation and home heating are tied to it.

Those load profiles in aggregate would most certainly but pressure on the system both in transmission of electricity and production of energy.
I think I had as much as $30,000 in my new FTX.us account (I was loyal to Coinbase, but inept officials in Hawai'i banned crypto and I was kicked off Coinbase and needed another exchange). So I should be angry.

But I'm not. At least not yet.

Something seems phishy to me. I think SBF might be telling the truth. Or he could be lying. I don't know.

I'm 50/50 on this one though.

FTX.us was a good product. It was snappy and it worked. Until the lawyers took over. SBF says it was fully solvent and I have not seen any proof that it wasn't.

The sheer quantity of "he's guilty" comments on all of social media reads like a well organized PR hit job (similar to this: https://twitter.com/breckyunits/status/1613178467818024962/p...).

The one lesson I think everyone can take away from this is: as much as you can, #buildInPublic.
The sheer schadenfreude generated from the wunderkind that still appears to be under the impression he'll be able to talk his away into a better position.
For fun, I recommend opening the SEC's case against SBF [1] and searching "tweet" and "television." They are building their case every time he opens his mouth.

This is why if you ever find yourself in any kind of serious legal matter, take your lawyer's advice and stop talking. It doesn't matter how smart you think you are. Prosecutors will use your words against you.

Yes. He can write a million words, but the issue is misusing ringfenced customer funds. I didn’t see that mentioned in the post at all.

Are you sure that unions are responsible for the EU laws? Can you give any sources for that? I'm truly curious about it because the EU comes up with a lot of good consumer protection and worker laws and it's not obvious what motivates them to do so. Just as example, the law about universal phone chargers. Industry certainly didn't push them for that. Quite the opposite. So where did it come from other than it being a big plus for consumers and in reducing waste?
Same here at less time (~6 years and I think I've been contacted once while on vacation). It's definitely a culture thing and if you have a lot of siloing then you're going to have this problem.
I presume that “arc” means “automatic rc”.

What’s manual rc like?
Why did _you_ bring it up in the first place, then?
If they’re so risk averse, why are their systems failing so severely?

It’s absolutely a corruption issue, in that the government prefers to pay 2-3x what they would to solve things internally to contractors who then perform a poor job and lobby to keep whatever they build in place for decades.
It's no different from any other type of server I think? Crowdfunding compute comes with a lot of security and privacy concerns and often if you're building a product putting that part of it in the hands of someone reliable is preferable.

It depends on what part of what you're building is your core intellectual property and such.

I'll ask back: what products would you build on top of a crowdfunded-compute GPT like model?
It feels like the skeptics, who were pointing out last year that the rates on crypto yield products, were too good to be true, had a point.

That's Celsius, Voyager, Blockfi, Genesis and now nexo all in some level of financial/legal trouble.

The question is how much is still to be uncovered.
Side hot take:

1. “AI” requires compute time for training (GPT, etc.)
2. If you use any “AI” service in the future, you could have to share idle computing power to improve that “AI.”
3. This may be tokenized via crypto. More contributions = more “AI” usage available for you.

Could the use of tokens or cryptocurrency incentivize participants to contribute their idle computing power to facilitate the process beyond those with deep pockets?
Jürgen did it all before in the 80s, however it was never translated to English so Geoffrey could happily reinvent it.
I’d be more interested in closed co-ops where individuals provide computer power in exchange for access to the model. I think freeloaders will eat up compute time.
I have the lowest end Roomba purchased in 2019 that I block from internet access at my router. I can’t use the app but there’s a button on the vacuum I can use to start it. Works enough for me shrug.
my headlights aim down, and I've taken pains to ensure that they don't aim higher than they were supposed to stock. I recognize that others do not do this.
Yep something I keep seeing in his interviews and posts is that he will talk enthusiastically and at length about how some external events caused FTX difficulties, but will ignore or hand-wave some actions that he actually did.

The impression I get from them isn't "oh this is a really unlucky guy" though, it is "oh this guy is quite a skilled manipulator".

I also liked when he did a Good Morning America interview and looked like a schoolkid who was caught cheating and tried really hard to look like they're sorry: https://twitter.com/sracka_omacka/status/1602469299113066496

Lack of reality based thinking coupled with adhd stimulants that on initial intake create a euphoria and makes you feel even more grandiose. That's when reality based thinking goes completely out the window.

He has no objective capability anymore to be self aware, and it's made worse with prescription drugs.

When the feds come knocking on your door asking about several billion dollars going missing, and you let yourself do the talking via blogs and interviews versus your team of lawyers, you have absolutely lost your mind. Certainly don't add adderral or alcohol, or anything to the mix. Go into a small dark room and smoke some weed you junkie crook. Keep quiet, your inner circle already ratted on you. Have some respect for the $250 million your parents scourged up to bail your stupid ass out, reprehensible fuck.
His problem here is that the two businesses were deeply co-mingled. If it was a genuinely seperate entity then it would be a much stronger argument.
He's smarter than a lot of people think. He may very well be the smartest in the room despite appearing dumb.

The problem is even a smart person dressed as a clown will be recognized as a clown. At some point you can claim not to be wearing clown clothes until you are blue in the face but no matter how dumb the person is you're talking to they won't believe it. He must hope he can convince 1 in 12 people he is not a clown.
The issue is these people are bored, they want challenges, and they want to try and build the things they dream up because they're curious to see if they work as expected.

Give them a library or tool to build that the team can use, something with a clear boundary from the rest of the code base, and that has a fairly limited domain/scope so it won't need constant maintenance.
yeah working for government is strange. I'm in a position where the product owners don't want to make any enhancements/changes to a production system out of budget concerns. However, the actual invoice for my team's time is the same whether they make changes or not. They don't want to "spend the money on enhancements to a functioning system" but the invoice amount is the same every month regardless.

oh and in my experience, government fte's can screw up an infinite amount of times with no risk to their job.
> he started to actually believe he can just make up reality.

Yep, I believe he truly believes his own BS. Like probably the rest of the crypto scene.

And, like, well, increasingly huge portions of the whole damn country and world these days? It's a make-your-own-self-serving-facts world.

But yeah, I think he truly thinks he's some kind of a victim here, of some kind of a takedown of a solvent FTX that wasnt' doing anything different from most everyone else in the space (that might very well be true?!? it's a space built on BS and playing fast and loose). And probably truly feels bad for those who got screwed by it. He just doesn't see how it's anything he's responsible for. Isn't this the way all those people getting rich got rich, isn't this just how it's done? Isn't that "disruption"? He may not be wrong.
>> a clear statement of the importance of the team's overall success, not their personal triumphs

This doesn’t jive with my experience of devs i can see fitting with the OP’s description. Talk of team success just isn’t on their wavelength, you may as well talk about the weather. It’s a different value system, it values heroism, it values cleverness, it does not value useful business outcomes like maintainability or cost of ownership.

For keeping them on track, they can sometimes respond to automated controls better than to people telling them what to do. A linter in the CI pipeline will usually cause them to follow a style where another person could simply never convince them to make the same change. But everyone’s different and so even this is not guaranteed.
The area is already planned for mining and nobody lives there, it is right next to the largest iron ore mining operation in Europe. Wouldn't even need to move workers, since they already live next to it.
>> I can’t quantify why, but the quality of heating feels completely different and I’d much rather use it.

It is because your wood stove is radiant heat. It is pumping out IR radiation which is heating all of your surfaces, as opposed to heating air that is then moved around your house. It is the difference between standing in a warm breeze and standing under a heat lamp.
