To me, the old cook was the hero of that song.
Yeah, I spent a long while (years) using pretty much exactly the solution he describes, as implemented in emacs. It's not as good as a tree, because undo/redo cycles make it very annoying to traverse through the history. I greatly prefer undo-tree.
Apple is already doing search on a huge scale and will continue doing it -- that's what the "Siri Suggested website" is that shows up when you type in Safari's search bar, on both iOS and the Mac. It's under the radar a bit, but it is absolutely the same search.
This website we are using, Hacker News, is making your (and my) computer send data packets to the USA. My understanding is that this is not in line with the GDPR. I like to talk to you. So yes, I have a problem if this communication channel gets closed.

The Dunning-Kruger effect is a cognitive bias in which people wrongly overestimate their knowledge or ability in a specific area. This tends to occur because a lack of self-awareness prevents them from accurately assessing their own skills.

I mean Twitter already had process like that in place and many people trusted them with that.

And I'm sure many large company, politicians and so on would have gone threw the verification process.

Of course now maybe some people wouldn't anymore but when he took over twitter announcing that as a policy seem reasonable.
You're thinking of a particular kind of battery with a flammable electrolyte. Other popular chemistries (LFP being the most obvious) aren't anywhere near as fire-prone.

And of course, laptop batteries get worked -much- harder and treated to much harsher environments than any EV battery.
I mean, every top ranked bbq joint in Texas uses it. Sone of the better BBQ restaurants in the UK import it.

Aaron Franklin has gone on about why and it’s because of the long cook times. BBQ is smoked and seasoned so I’m not sure the bland opinion matters.

Ask HN: What shell do you use, if not *sh?
I don't know bash. I don't want to know bash, I am not interested in a language that uses the program [ for if-branches. (Also I don't want pitfalls in the simplest possible tasks, thank you very much.)

I am looking for a shell language, with the following criteria:

- fairly popular and alive
- is small, like putting a binary in the /bin folder
- can start programs, support pipes, file operations
- has variables, if branches, lists, for loops, basic integer arithmetic, strings
- not POSIX compatible, or resembling to bash

Google offers a handful of options, but I am interested if people actually use not bash or bash alike languages for shell scripting.

This is a drivable road regions (obstacle detection) algorithm found in what appears to be a git repo leaked from an autonomous vehicle company in 2017. The repo was available through one or more Tor hidden services for several years.

The lidar code (in an almost-C dialect of C++, a ROS node) appears to be written for the Velodyne HDL-32E. It operates in a series of stages, each stage refining the output of the previous stage. This algorithm is in the second stage. It is the primary obstacle detection method, with the other methods making only small improvements.

The leaked code uses a column-major matrix of points and it explicitly handles NaNs (the no-return points). We've rewritten it to use a much more cache-efficient row-major matrix layout and a conditional that will ignore the NaN points without explicit testing.

This is an amazingly effective method of obstacle detection, considering its simplicity. We've tested this using a VLP-32C lidar, user manual here if you're interested:

"Tech worker" is not a very useful term for understanding labor markets. What I'd like to see is a chart of the occupation specific unemployment rate for software developers in the United States. The BLS definitely produces such a time series that should have been updated for October, but I can't seem to find it right now.

Broadly speaking, either they are financially illiterate, or they like gambling. Or both.
We already tried that, that was the wave 2 of Crypto, when people were trying to build tokens with utility. Things like Filecoin.

Eventually everyone realized that the value-add of the utility those tokens bring is roughly ~$0, and the only reason tokens in general, and those tokens in particular have any value at all is because people buy them so they could sell them to a bigger fool.

Token producers thus took the next logical step[1] - dispense with any promises of token utility, and go straight to minting NFTs and fartcoins. Why bother actually developing a product and ecosystem when the only thing people buying from you care about is the pump and dump?

"He is reportedly the company's new vice president of engineering."

LOL. Many people have that title at Google, there is not only one.

[EDIT. Scrolling way down I see I was not the first to point this out. At least two of my friends have had that title at some point there. ]
I wouldn’t go so strong as this.

The civil service is mostly designed to provide some level of basic stability and functioning so that no matter what flavor of the month politician gets elected you still get your trash picked up, and other services. (If politicians directly target something, though, all bets are off.)
This sounds logical and hopeful, but even a casual survey of the current lot of political leaders on all sides is very disappointing. Donald Trump, Joe Biden, Kamala Harris, Hillary Clinton, George Bush, Barak Obama, Pete Buttigieg, AOC, and even the once heralded Bernie Sanders (just to name a few) have turned out to be massive failures and disappointments.
There is TinyGo, and its becoming more of a thing, in Go circles.
So interesting, because I had the opposite response. Sure if I donate my body to "science" and it's critical in some sort of medical discovery that would be great, but reading the OP and seeing the author's fascination, learning, and engagement with the cadaver I thought, "Gosh, what a gift!"

I'd certainly be very happy knowing that my body brought such an experience to another individual, I certainly won't be using my body anymore at that point.

I wonder if, when signing up for donation, you can specify what kinds of "science" or interactions you prefer your body to be used for after dying.
Memory safe code does not prevent applications from using too much memory; it prevents applications from accessing the wrong memory (e.g., by using a variable after its underlying value has been freed and the memory reallocated).
I wish they had a cloud offering, it's something I'll look into setting up one of these days as I've been getting more and more motivated to move some of my lesser used/stable projects to the cloud so I don't have them on my main machine and can access them quickly if I'm away or a client needs some change. I've heard good things about https://www.gitpod.io/. Also funnily enough I have a m1 mac and I use lando on it without any issues whatsoever, other than starting docker I don't interact with it at all.
Ask HN: Can I Know If My Website Is Being Spoofed?
For example, say I own "bank.com". A phisher purchases "bank.evil".

They make the login page at "bank.evil" look like the one at "bank.com"

Whenever a victim goes to "bank.evil" it connects to a server, that connects to an automation-tool, that connects to "bank.com"

Whatever the victim does at "bank.evil", the phisher's browser does at "bank.com".

Any solution that has you perform an action on the site that initiated the request might just be the evil site asking for your information for the legit site.

Are there any techniques or products that foil this threat?

- OTP, SMS, Push, etc would fail I think because you're putting the proof that you own the account into a tainted site.

- WebAuthn might work because of the SameOrigin rule

- E-Mail might work because you sever the instructions from the spoofed browser

Thanks!

Rumors were that he was still trying to raise some kind of last minute savior financing after Binance backed out. If so, his best cards are to show that not everything he has is a shitshow and there may still be some real value financiers might be able to buy for pennies on the dollar if they save him from complete collapse.
Agreed that private lists may cause collateral damage due to false positives. But if they also help people avoid abuse then people will obviously continue to use them despite this.

Given that it is impossible to outlaw rumors it is ultimately up to those in power to ensure that reporting misconduct via the proper channels is more effective than relying on private lists. Given how many people feel unsafe with members of Parliament it is unsurprising that they resort to alternatives to keep themselves safe.
This blows my mind...should you use the biggest public offender of data stealing for keeping your privacy hidden. Complete idiocy.
Its just pretentious BS used as a smokescreen for _gambling with your money_.

What has happened with FTX is a demonstration of the value of a block chain and the concept of user-controlled wallets versus banks. FTX did what banks do, which is to take a cut of transactions, and especially use customer funds to make bets (that eventually they could not cover, even with all of your funds).

Using centralized exchanges to speculate is a ridiculous perversion of the concepts in cryptocurrency.

The basic advances of cryptocurrency are:

1) digital signatures used in transactions rather than disclosing secrets such as credit card numbers

and

2) a public ledger that is cryptographically verified with chains of blocks

Decentralized exchanges are probably usually also often nonsense speculation, but if done right they can at least benefit from 2 which means you can see what they are doing and not be surprised at the last second about some secret "over-leveraging".
> For example a supplier could sell you 5 kWh per day at a fixed price, and anything extra you use is at instant market price, with some kind of pay-as-you-use system.

I suspect 5 kWh/day is way to little to keep the house warm and still be able to cook food. The exact number doesn't really matter here. What's more problematic is how the 5 kWh of guaranteed/insured/subsidized power would be allocated.

If it's your first 5 kWh/day, it will be you'll blow past the quota by noon, and if there was a price spike in the evening you would pay the full price of it, or shut off your breaker until prices go down.

Having it as a some sort of pool you can draw from anytime you want doesn't suffer from the above problem, but would make such a service very expensive to run for the counterparty due to adverse selection. Anyone using such a service would opt to use the market price when electricity is plentiful/cheap, and switch to fixed price when electricity is scarce/expensive. The net result is that the 5 kWh ends up always being the most expensive electricity for the day, and a service providing such a guarantee will be priced accordingly. In a competitive market, you would expect the price of a fixed price plan to be the same as the "5 kWh per day at fixed price and anything extra at instant market price" plan that you propose. You might be tempted to argue that utilities/the government can subsidize the latter plan as some sort of green energy initiative, but that would be be bad. The most expensive energy also tends to be the dirtiest, because peaker plants (power plants that can quickly turn on/off) tend to run on fossil fuels. Subsidizing such a scheme would also be subsidizing electricity consumption during peak hours, and therefore subsidizing fossil fuel plants.

I agree that as headlines go this one sounds sensational; but Twitter threads lack headlines. This was the first complete phrase that fit within HN's title char limit.
> he was a lucky, successful asshole

I know contemporaries of Jobs that had every opportunity he had, and failed to notice those opportunities.

I'm one of them. It was obvious in retrospect. I missed it, and many, many people I know were blind as a bat.

There wasn't any particular magic in the hardware or software of the Apple I at the time. Yes, Woz did a great job doing it with fewer chips. But that was not key to its success.
No one is writing kernels, raw register level volatile DMA bit-banging embedded code, and other "impossible without unsafe" code in Java/Go (Ok, almost no one, don't @ me, pjmlp, there are kernels built in memory-safe languages and there's tinygo for embedded etc. But they obviously use unsafe all the same). So they don't need to use it as much (standard library, core primitives and runtime implementation notwithstanding, and boy oh boy is it unsafe!)

Shifting the discussion to Vulns., Modern C++ is moving the goalposts a bit, don't you feel?

> Forbidding unsafe code doesn’t guarantee vulnerabilities are gone
It does, because if it doesn't, or GC'd languages offer more protection, then it's a bug in rustc/spec/core libs, for all intents and purposes.

Might as well mention /proc/self/mem and other filesystem/IO related exploits, because Rust can't protect you from them, and therefore it's completely and utterly unsafe and unfit for use.
Algal supplements might be the easiest way of doing that. (That's what I currently do.)

And from what I understand it's mostly micro-algae with EPA/DHA.
The team in question had decades of c experience, and was doing all new stuff (maybe half of all work?) In autosar. I was working with them on an unrelated C++ project and I can assure you the C++ they write was not very good since the only C++ stuff was things they didn't want to do.
I would rather quit YT or use it only as a source of links for yt-dlp if I meet this restriction. I usually watch it in 2x-3.5x with some custom one-liner in bookmark which edits a special parameter for achieving more than 2x speed, but sometimes I really need 0.75x if a quality of sound is far from decent.

I'm curious what was the intended utility of their FTT token and ICO?
Was the token meant to be a type of equity in the FTX exchange then?
How much of that pollution is coming out of the tail pipe vs. off of the brake pads and tires?
I think what vim has is different and better than what OP describes - it's two separate change logs, one for undo/redo and one for time-based jumping. Trying to fit both of those constructs into one list gets messy.
Thanks. So what does it mean for a program to be memory safe if it can still memory leak? An example or pointing to a resource for further reading would be much appreciated.
Not technically shell, but Python can get you fairly close to that.
it's reasonably hard because it takes an experienced player to not inadvertently make up rules that seem simple in their head but are actually super hard to guess. but if you do have that experience then the game is pretty accessible to kids, and should certainly appeal to mastermind fans.
I don’t think Carbon will have a borrow checker. I am under the impression it’s just checking array bounds and adding nicer syntax
> The Arduino IDE is totally unsuitable for it

No one that uses the Arduino library/hardware/ecosystem on a serious level actually uses the Arduino IDE - for what it's worth. The Arduino IDE is supposed to be for beginners to get started really easy.

For everyone else, use what you want... be it vendor IDE's (ie. Atmel Studio), PlatformIO (for your favorite IDE), etc.

There's nothing special about Arduino that requires using it's official IDE.
I just started learning OpenMPT earlier this week together with my daughter, really seems to be the easiest around! Thankyou :-)
Again, non of this is even close to 'buddy buddy'.

Buying raw materials from Russia isn't surprising. And SpaceX is not a arm of the Ukrainian military.

The fact that Starlink helps Ukraine as much as it does disproves that they clearly are not 'buddy buddy'.

At best you could say Musk is not an absolutist enemy of Russia who 100% supports Ukraine in each of their actions.

That's partially true, there are other tradeoffs that can be made to optimise power and thermal dependence at the cost of something else but both specific use case and fab availability/reliability need to be factored in.

>this is sad because youtube is and always has been extremely resistant to public pressure. it doesn’t matter how much people complain, this is going to happen.

Well of course they are. YouTube isn't a public utility. And we aren't its customers, we're its product.

I think Instagram, youtube, and even a couple of porn sites have realized that they get really good engagement out of their product (users) with shorts and that's why they're doing it.

HN folks are not the target demographic, and we're a tiny minority, so they don't care what we think, even if we're justifiably annoyed.

I'd love to see a better algorithm on youtube too, but that's not their priority.
A lot of these selling points sound like features that Nix already has. What does Spack offer that Nix does not? Is it documentation? User experience? Wider support for computing libraries?
Everyone, everywhere, knows something that you don’t. The more we can lean into this and share context and curiosity instead of judgment, the better we will all be. That said, I realize it’s simple to understand this, but not easy to implement, which is unfortunate.
Yeah republicans and conservatives are amazing at organizing and keeping order in the ranks. Trump threw a wrench in some of that, but then they come out with things like the Lincoln Project that work really well (unfortunately).

Average Dems in power will do anything to keep Social Democrats out of power. Even if they are all still capitalists. The Democratic Party would rather lose to Republicans by a bit than cede power and in my opinion more freedom.
For what it's worth, I remember someone shared Pleroma code in the Elixir forum and some veterans there said it was a very non-standard way of organizing an Elixir codebase.

It could be possible that Pleroma is not very idiomatic Elixir / OTP.

So more non-existent things? This entire discussion is oddly circular. Given <thing which does not exist> I can do thing <which cannot be done>.

> you can think of the GG’s appointment as being done by the Sovereign — just with the nomination process delegated to the country’s current PM in order to minimize the Sovereign’s workload

Is there are practical difference between this description and just saying that the country's PM does the appointment? I guess one test would be what happens if the sovereign decides to override the PM. What happens then?
Not the person you're responding to. But I concur. How will one separate money from state and then protect one's state-separated money without themselves becoming a "state" of sorts, that then is fused to their money? And then everyone becomes their own little island/state, that is fused to their money, and then you forge alliances and become allied island-states, and so on and so forth, until you become a nation of sorts?

Like cmon now. Isn't that the inevitable progression? And if so, doesn't that mean these folks who insist upon separating state from money just want to become the ruling class?

I dunno. That's just how it always comes across to me.
Speaking of the Super Bowl, their ad aged really poorly. Someone posted a clip from it[1] that has Larry David being pitched on FTX as being a safe way to get into crypto, and he turns it down, saying he's never wrong about these things.

The joke is supposed to be that he's being comically clueless to do so, because it follows a series of shorts[2] of him not "getting" the point of advancements like the wheel, the fork, the toilet, the Walkman, etc. But now he just looks wise!

Also there is the psychological factor of the staff member watching the ipad screen the entire time, and looking at it again immediately after you are done. Like are you going to put zero and have them think "Fuck you cheap asshole" or are you going to be guilt tripped into throwing $3 away that the staff member might not even see? It taps into the same moral dilemma as a beggar accosting you on the street.
I remember some statements around pricing for Tesla models by him that made me wonder (I think it was something like 'a Tesla model should cost the same amount everywhere on earth', which struck me as both admirable and naive), but having built up multiple billion-dolllar companies it's hard to deny that he must have made a lot of good decisions.

I think there may very well be such a thing as business acumen, I know several people who were succesful building multiple businesses in different industries (nowhere near a scale that you'd have heard of them, but still). Some skills like negotiation, sales/marketing/PR, motivating employees, being good with numbers,... are universally useful for all kinds of business.
