Petrol taxes include road tax in a lot of places, that will have to be replaced somehow once the share of electric cars becomes big enough.

Thinking about energy usage always puzzles me.

I'm not even sure if driving a car from one city to another really uses energy.

For example, let's look at it this way: The energy from the sun is heating earth. When we use some of it to drive a solar-powered electric car from one city to another, does that lower the temperature of planet earth? I would think it does not. So why did we get the energy to drive the car for free? I would think that the surprising answer is: Moving something from A to B does not use energy at all. But I'm not sure.
This must be for show. If ByteDance or anyone else is sufficiently motivated to distill OpenAI’s models, it can’t be prevented. You can simply pay other people to collect the data for you.
Like internal combustion is any better at this.
BuildC: Tool to build your C/C++ projects
I'm learning C++, and I found it irritating to write every file's name in the compile command. I wasn't able to learn CMake, so I built this.

In the bluetooth spec? For various non-computer things, like being able to pair your first controller to your playstation, without having to plug in an usb mouse to click ”allow pairing”

On the devices affected? Who knows
400K LoC is still far too huge for that kind of flexibility. Most of lines are probably attributed to the "batteries" included in Log4j. For example `log4j-core` contains too many plugins by default, including the notorious `JndiLookup`. It may have a modular interface, but its packaging is much less modular than it should be.
My concern is safety (car wreaks), distaste for touch interfaces (also safety related) and the environmental (ironic, I know) and social impact of rare earths mining.
Right now, electric cars are still at a disadvantage because of lower production volumes. It's not only the material cost of the battery and the motor that makes them more expensive, but also the share of the development costs that each sale has to recoup. In the not so distant future I think petrol and diesel cars are going to be at a disadvantage because of this.

I still own a quite old (12 years, but low mileage) petrol car, because I don't drive a lot and really only need it for errands in my city. In this scenario it's very hard to justify buying an almost new electric car. The used ones available on the market right now are still not very attractive in my opinion.
Can confirm. Financial literacy is fairly thin on the ground here.

I didn't realise how pervasive this was, but yes 90% of new car purchases are using a PCP.

I wonder do any of them realise they’re paying the maximum depreciation every single time too. Losing 20k+ in depreciation every year feels like a great way to stay poor
Just saying the word "AI" and the ring may render you invisible. Put something in front to give it a "one ring to rule them all" ring, e.g. "Hyper AI".
I was traveling with an EC in countryside Italy 2y ago and had no problems finding public chargers.
How do the economics work out for the seller? Depreciation is highest at the beginning, when these people are paying the per month price. If they can't afford a loan for the price of the car, how are they making a lease payment that covers the depreciation for the leasor? I'm sure there's a reason but I can't think of it.
Well I have used VR with hundreds of people at events. There are some people that have an adverse reaction pretty much instantly.

The rest might have some discomfort (though our experience is tailored to that with teleportation instead of smooth movement etc) and they are fine. If they use it regularly it will go away.

I've only seen 2 people that really were not ok with it. It happens yes but it's not a huge amount of people.

Also, don't forget, the phenomenon is only when the movement in VR doesn't correspond with the physical space, usually because the virtual world is much bigger. But for many things like productivity scenarios, moving around long distances is not really a major need.
Which also seems a bit wild to me.

I won’t buy a new phone let alone a new car.
It's not so much about getting rid of the cars (just yet). I agree that electric vehicles don't solve the underlying issue. But we first need (we in North America, at least) a build environment designed for humans first (basically, copy what the Dutch have accomplished).
Even with SSDs, it's only laptops specifically that made a wholesale shift to SSDs. Why? Because laptops get jostled around, and SSDs are impervious to rough handling.

Over in the land of desktops, servers, and other stationary computing installations, HDDs are still superior if you do not explicitly require (or want) the fast access speeds and latencies of SSDs which are oftentimes overkill for most use cases.
Wake from suspend-to-RAM (and likely with a radio power up) is going to be gobs more expensive than a wake from retention because you're both coming from a much lower power state (you were doing great before and now you're not, so a big change in energy usage over baseline) and it has a high overhead (the core cluster/SoC has to go through power on reset and get reconfigured by SW). This greatly contrasts with a wake from WFI where at minimum all architectural state is retained but generally caches and predictors are retained for quite a while.
No, it will be an engine that produces the same output if given the same input. It's like saying Google reverse engineered Yahoo and built a search engine
It's going to be stupid for openai to argue that those terms are binding when they've already argued in court that those terms are nonbinding when they scraped other people's dat.
Having worked in a few extremely large organizations myself, I've never had this term used. Only on this site.
SSDs also had an inflection point when floods hit Thailand knocking out plants where a good chunk of spinning rust HD motors were made. Spinning drives exploded in price pushing people to accept a smaller but faster SSD and deal with it.

> We observed the first uptick at the end of October, reaching its peak in the first week of November with price increases in the 80-190% range for desktop drives and 80-150% for mobile units. Although we're beginning to see price reductions across the board, on average drives are still about 60-90% more expensive than they were before the flooding.

Custom is usually bad, just takes longer to reveal the problems. Sometimes companies need to create custom things, the mistake is continuing to invest in them when a community project appears and doubling down for years until nobody in your org knows how it's done "normally" and nobody that you hire knows anything about your stack.
That's a fair point, and I'm not arguing people should rely solely on police for their personal security. I'm more pointing out that it's clearly correct and appropriate to report crime when your safety is in danger; that I'm not trying to argue for some extreme where crime is never reported to the police.
If you have the liberty to limit your team to a subset of modern CSS features that have predictable behavior and patterns of applying styles (like never putting margins directly on a component, always spacing things from the parent; along with a laundry list of other conventions); and your site is designed to not do weird painful stuff (eg masonry layouts, though that should become a native CSS thing soon!) then I find it’s pretty predictable to do 95% of layouts, and only the weird outliers require special sauce. But then again I do a B2B SaaS that doesn’t need to look shockingly sexy, with lots of standard CRUD dashboards so maybe our use case is light on weird CSS tricks required.
If you can silently pair to a phone, you can make the phone dial whatever number you want. Recently found this out when connecting the serial terminal to an earbud for repair (it wouldn't auto-connect to the other earbud).
Way too chunky. And no AAC?
I totally agree with you. When I’m thinking about switching to, say Tesla X, I need to explain myself how that could be cheaper during lifetime (how long is that by the way?)? The sticker tag is 10 times of the money I paid for my used one and on top of that insurance will cost as much as another used one. Only the first year of owning Tesla x will cost as eleven cars like I have now.

But that comparison would be more fair if I will compare with used Tesla. Not too many around though.
The music player I had in the early 2000s was also identical to the music player I wished I had. It was a Zen Stone; a tiny device with flash storage, a USB port, and an audio jack. I plugged it into a cassette tape adapter and used it to play music in my car.

It had no screen, so most of the device was covered in buttons that could be easily used without looking at it.

The company followed up with a sequel model, the Zen Stone II, that was worse in basically every way, a trend that more or less continues to this day.

Every time someone puts a screen on a music player, they decide that using the music player should require looking at the screen. (As here, where the buttons are images shown on a touchscreen!) Why?
The test-and-set lock has the "advantage" of being unfair. Being unfair could be seen as a problem, and indeed it is, especially when access to memory takes a time that depends on who performs the access. However, if the lock holder could be preempted, and you have no way to schedule it back, it will cause all waiters to delay even if one is runnable, and that will quickly send performance down a cliff.

For that reason test-and-set spinlocks are sometimes used in userspace or in virtual machines.
AutoMix: Automatically Mixing Language Models
I’m guessing nobody was using it. I think Figma became successful (apart from being a good product) because it was free, so developers try it in their free time, and bring it into their company
Um.

There’s this little detail of efficiency. Much less than 100% of energy used for acceleration and overcoming friction is actually spent on those. Most ends up heating up random stuff like engines, brakes, roads and tires.

I’m confused why do you think anything could be moved from A to B for free? You have to charge the car, or fuel it up, after all?
Indeed, making poor people in 3rd world countries rate the worst sludge of the internet for 8+h a day might backfire on your marketing... OpenAI could risk it, Google maybe doesn't want to...
You can still pay employees to write software and treat it as a regular expense. But if you want preferable treatment for R&D expenses now you need to amortize over 5 years. That’s all.

This is actually pretty awesome. I've been using Xcode Cloud to build and submit builds for my apps since it was first announced during WWDC 2021. As an indie developer, it definitely helps a lot to not have to spend absurd amount of $ on third party services and also frees my time to do other things.
I’m running an entire ETL pipeline with sprocs, functions and triggers. It works extremely well, has been running for several months without any downtime or interruption.

Snowflake introduced their marketplace and those apps / data shares necessitate sprocs and database functions. I made a couple of those apps in my last role and versioning is definitely a challenge. Rolling back is easy enough but what do you do with lost/corrupted data?

I have worked on a small CRUD app where everything was done with sprocs with a small laravel layer and that worked well enough.
Can anyone explain how conv works in that graph. You have a tensor of shape [2,4,16] and you convolve with a kernel of shape [4,16,8] and that gives you a [2,8] tensor? How's that possible?
Rare earths are not a major component in car batteries. They are mostly used in the electric motors for the magnets and it's acutally quite easy to replace them. Mining of lithium, copper, nickel, will have to expand in the future. But it's nothing in comparison to the damage that is done with the extraction of oil and gas.
Maybe. The web became popular because third parties, Spyglass and Mosaic, evolved it into something visually appealing early. Competing internet applications didn’t have this except maybe email with its pseudo-standard form display of address fields and subject line.

The goal and intention of the web was always sharing information via hyperlinks such that the collection of links naturally forms its own descriptive metadata. In this regard the web has largely failed with content being relegated to walled gardens. The very first step in this regard was Roy Fielding updating HTTP into a series of methods describing database operations, as opposed to merely transmission or content description, and nobody challenged it. In that regard the advancing malicious actors were early and close to home.

If I were to learn from this and create a competing application I would ensure from the very beginning the technologies are single paradigm, extremely primitive, and fail if extended beyond their isolated area of concern so that malicious third parties are forced to advance transmission and content each in isolation from each other and from the underlying technologies. I would also ensure there is a single convention to describe both content and interaction because absolutely cannot figure out the front end.
My memory of the early ish days is that Facebook heavily leveraged Google contacts (which was allowed by Google) to discover friends, and then blocked others from doing the same. Is that correct or can someone offer better info?
I only new because buying new means I do not have to worry about its history, it comes with manufacturer warranty.

Buying used is rolling the dice on whether I end up with a Hangar Queen demanding attention I don't want to give.

Time is money, as the saying goes. Buying new is more expensive, but it's cheaper in the long run with the time and money I did not have to waste on unexpected upkeep.
This is an automatic bluetooth pairing attack. With the right equipment (which can be as simple as a Pringles can and an antenna aimed through a window) you can execute this attack from a hundred meters away. That's not physical access.
On a computer, you could conceivably hide a poisoned sudo/su somewhere and add it to the $PATH.
On the flip side, using PCP means that you get a brand new car and it has a warrantee. You could buy a banger for £500 - but then you're always going to be wondering if today is the day it'll cost you £££ to repair. And if you can't get in to work, that'll cost you dearly as well.

£300 per month to basically not have to worry about any unexpected bills seems reasonable to me.

Plus you get the social value of having a "nice" car. The safety features are likely to be higher quality. And, as mentioned in the article, newer vehicles tend to be more efficient.

Basically, it is a fairly rational way to spend money.
Ask HN: How do you research niche technology businesses?
I enjoy building things and have typically just built something to see if anyone wants it, because it was fun to build it. But I'd like to take a little more directed approach in the future. The problem I'm running into is I can find a lot of info on how to research, plan, and execute a VC scale business, but not much on finding a niche or lifestyle tech business. Some of the startup school advice still applies, but honestly not most of it. And I have found through experience I don't really enjoy the "get a million, scale as fast as possible or die trying" approach. Possibly because all mine have died trying, but still..

Making cheaper and less featureful versions of successful VC funded projects seems like a possibility, for example, but also kind of vague. Is there anyone writing good quality guidance on this, that isn't scammy? Or does anyone have anything to share?

My goal isn't to get rich, but to generate some passive income while building interesting things while I'm in semi-retirement.

If there isn't good guidance out there, what would you say are the most important attributes that make a good business of this kind?
I got a Shanling
MP3 player when looking for features like these, and I've been very satisfied:

3,5mm jack, no Android, physical volume button, SD card, all audio formats, high quality Bluetooth, high quality output, good price and sturdy. Battery is not great, but it's okay.
I think the main goal of Xcode Cloud is to offer a first-party, out of the box solution for CI/CD. You'd be surprised how crappy (and expensive) GitHub's experience is when it comes to iOS and macOS builds.
That’s not the only thing. Electric vehicles are generally cheaper-built compared to gasoline cars at the same price point. They have cost- and weight-saving compromises that make them tangibly feel less valuable.
Given that many western companies hire poor people to do all sorts of horrible work I doubt it’s that. More likely it’s to avoid suggestions of bias across their product range.
There is a big shift in prices coming with Sodium Ion batteries. At about 1/4 the price of Li-ion they save substantial money all be it a little less dense. For all but the highest range cars Sodium Ion is going to do the job and BYD is talking about $12000 cars. Not quite a cheap car yet but still given the savings electrical vehicles bring on running costs its a significant step.

Its not just volume production the materials in the batteries are driving a lot of the high price. You can get a second hand Zoe for £4-5k but they are quite limited in range. A full range EV for £12k is going to be a big deal.

Petrol fire is undoubtedly easier to come by and more dangerous in case of a crash. Touch interfaces aren't specifically tied to electric vehicles; it's a common disease on all modern vehicles, fortunately on the decline. Environmentally, in countries with reasonably balanced (i.e. not China and Poland) power generation, EVs are *way better* than ICEs, without the slightest room for debate.
It can be more instructive to consider entropy rather than energy usage.

The energy coming from the sun has low entropy and that makes it easy to capture and convert into electricity/plants etc. When you use some of that energy to move a car, you're converting the useful low entropy of the electricity/fuel into high entropy "waste" heat that can no longer be easily captured and used.
I’ve encountered developers who want every implementation detail written down before they start work. I’m not exaggerating.

"So in return the company paying me my salary and only expecting me to work the required 8 hours a day would also be a C?"
Of course it isn't. I don't vote for internal combustion technology at all. Both are environmental problem. Looking at all the (ex) hype about electric cars, sometime it looks like electrics - they clean the environment...
Internal combustion will stay for a long time in heavy machinery, sea and air transport, which is also problem, if not prevalent, so electric cars will bring negligible health improvement to planet. And add all the wars - our efforts to lower carbon footprint on this planet are so funny and naive.
I need to add another reply to this drivel, to point out that No, I do not buy plastic packaging, plastic cup straws, or other silly plastic products that are essentially one-use.

LEGO is not one-use. The entire point of lego is to NOT be one-use. I'm starting to suspect you think the purpose of lego is to buy a lego model, build it, play a bit with the result, and then it's "done".

That's not how it works. Those bricks add to the pile of bricks you've got, to build creatively from. After a while, those 'piles' of bricks get changed to well sorted drawings, with different drawers for different bricks. ;) We use something like this:

I'm going to agree with you, because while he points out the problem - hardly a new insight - he doesn't attempt a solution.

This would be a much more credible pitch for his consultancy with an "Oh that's clever" answer to the problem.
> We all know all this "AI safety" is for show, right?

No. A lot of people think it really matters

A lot of other people pretend to care about it because it also enables stifling the competition and attempting regulatory capture. But it's not all of them.
Ok, but to continue this analogy, industrialization and the ability to create 1000 frozen lasagnas a second had an enormous impact on the world. Not only on the economics of production, but ultimately on human society.

Sure, handmade lasagna still exists, but the world looks nothing like it did 200 years ago.
While true if you haven't noticed it Solar and Wind are taking off at a staggering rate for electrical production. At prices around $15 per MWH they are substantially cheaper than gas/coal/oil electrical production. The economics just work out now in a big way and renewables are so much cheaper fossil fuels days are numbered.

Besides if you just car about the economics and not the potential reduction on the planet they are still cheaper to run over their lifetime compared to petrol.
I don't think we will increasy taxes for electricity. How do you even to that, when most cars are charged at home. The more likely scenario is that governments will impose higher road use charges. That has been a trend anyway in most of the developed world.
Support for retrieval is planned for year 2053.
See what I want to think about, but it is an unstable image flash against a dark background. Details seem there, but not enough persistence of vision to observe them. Can keep flashing the images as necessary, but it doesn't have the same persistence as reality or dreaming.
Yes, people afraid of rare earth and lithium mining should get some numbers right first: We extract 4 BILLION TONS of oil from the ground every year. In comparison, we extract a few million tons of lithium (and it's reusable / recyclable), and a few tens of thousand tons of rare earths.

The FUD about mining is pure big oil propaganda, frankly.
They've done very to promote it. No educational material, no community... just a handful of announcements.

Besides that, most companies already have CI pipelines in place for all their apps. Why would their switch?
Big power plants are more efficient than small ones, otherwise everyone would have a generator at home. The question is what difference batteries make.
