Rats are pretty choosy/smart about what they eat, most "toxic waste" is not acutely toxic enough to kill rats before they birth several litters, and AFAIK no rodenticides are under patent (the most recent one, bromethalin, is a horrifying product of rational drug design optmizing for palatability and delayed action - still it was invented in the 1960s or something). So probably not in this case
I think the word "hackish" really has a positive connotation here. (Look at the name of this site...)

You don't put metal threads into plastic in something that is exposed to vibration

...have you seen how a lot of modern internal combustion engines --- which vibrate a lot more than an EV --- are put together?
Yeah agreed. It’s something my wife and I have discussed a lot in the past few years esp. coming from families who actually worked with proper goods/materials. Working in/with software just doesn’t feel the same and like you, we have reached to similar conclusions and maybe, just maybe, if the stars align, in not so distant future, we kickstart the old family enterprise to build low volume, high quality products with guaranteed lifetime warranty (~20-30 years).
Simple financial engineering. Sometimes they take the loss but cover it up or push it out using lease terms. The company has profit now but takes a write off later. Good for juicing executive bonus packages.

Also because lease terms are complex they can stack with other promotions or incentives and allow for leases lower than the cost of ownership would have been otherwise. There is a whole lease community dedicated to finding these crazy deals but they wouldn’t be something you could do by just walking into a random dealer.
Yo, I’ve been using SuperMemo for 15 years (I set up a Google Alert for “spaced repetition” years ago). I started with foreign language words but gradually it took over my entire “memory life,” including positive memories, jokes and other stuff I didn’t think I would use it for. It feels like a secret weapon that isn’t so secret, it works great but requires discipline to maintain the habit.

Human kills already, and yet certainly do not want human to be banned for driving.

I too expect and accept that some accident caused by driverless car that kills kid/animal (that human wouldn't do) will happen (if not already happen). To expect otherwise will be unrealistic.
Tbf the unknown is risky. Tesla doesn't want to verify the fixes or the third-party. I agree the customer should have the freedom, but I understand the policy.

>How is the risk different

It's not but Tesla has decided to not participate in it.

Again, I don't think it's the right call, but it doesn't seem nonsensical either.
Reminds me of how they used to spray motor oil on dirt roads to keep the dust down.
Why did Windows use the FAT structure instead of a conventional linked list?
SF annoys me in an engineering sense because they chose a non standard gauge that has needlessly increased the cost of the whole thing. But yeah, carpeted cars is also insane (I see they finally removed that).

To be fair NYC system is maybe the best in the U.S. but they are all flawed enough I wouldn't praise any. My personal favorite that I have ridden is Tokyo's.
For those who don't know, Gizmos freeware, via techsupportalert was a software test and review site, running for about(at least?) 10 years. Volunteers tested and compared hundreds of programs, on the major three platforms; Mac, Windows, Linux and submitted their reviews. It was a first class site to find software that solved complex or mundane tasks. Movie editors, web design, graphics, text or hex editors, and so on. It was a very well organized catalogue for open source software. Test results and reviews were mostly useful and helped you decide whether complexity or quick first use were more important criteria for the user. Rankings also listed whether programs were freeware, shareware, demos, or had portable install options.
(And yes, in the last year, it suffered from the same fate as most of the internet, overloaded with 'extra' information. But the core was still there.)
It was a goto site for many of us in the community, and will be missed.
"if it was easy then everyone would be doing it": And, I suppose, we'd see them. Little green men, I mean.

>As far as the shoddy work, people keep acting like Telsa is a hivemind, and that every dept. in the company had signed off on these bad choices as a matter of corporate policy. Doesn't seem far more likely somebody working in the factory was worried about making quota, and did a very shitty job?

"You shouldn't have the right to make shitty choices! That's the Big Corporations' prerogative!"
You are in the bmw sweet spot I think. Newer ones have even more complex and expensive parts but reliability isn’t better and access is difficult
I mean, pure oxygen envs are pretty dangerous on their own, compared to pure N2.
If it’s a safety assistance feature, it’s not full self driving is it? My crosstrek comes with plenty of safety assistance features too.
Yes, although I think it is about an order of magnitude less of a problem than that.

My house runs at 60psi, +/-3psi, and I think it is pretty bog-standard for US plumbing. It's about 11m from the basement to the attic, and still needs decent pressure upstairs, so, yes, 2-5 psi is silly low pressure to worry about - it's only going to be a slow leak even while running, the only problem is if it runs out, for which I expect Tesla has a sensor.

This repair is not some janky hack, it is more of an upgrade
That's a really bad standalone definition. It would apply to randomly generating numbers, or most attempts at allocating memory and then sorting by address.
This is a nice article.

I know of a couple other resources. First and foremost is the site modernnomographs [1]. Popular mechanics once included a perpetual calendar nomograph [2]. Possibly pynomo [3], a python tool to make nomographs, would also be interesting to others.

Good writeup. Seems like it should also mention that he was banned from entering the US in 1952 after being convicted of having sex with a man. After reading his dislike for ship travel, I have to imagine that the cheaper air travel in the 1950s would have made a third visit more likely (if not for that criminal charge and his subsequent suicide).
If anything, Tesla seems to be going in the opposite direction, because their cars usually become available for lease only a a couple of years after the release. All while most other car manufacturers tend to offer lease options immediately on release.

Case in point: Model 3 came out in 2017, but wasn't available for lease until April 2019[0].

Other car manufacturers tried getting into subscription-based models a few years ago, but don't seem to be that successful with that. BMW introduced their All Access subscription model in 2018, it got discontinued just earlier this year[1]. The rest who tried similar subscription models seem to be going the exact same way too.

The vault complex is an amazing enigma I’ve been following since finding the name while browsing through some gene lists. Every cell in our body has this massive complex, it’s highly conserved and we have not a clue what it does.
Thanks for that link. The original site seems to be no longer valid. I wonder if there is a copy of the operating site somewhere, with all that hard work resulting in some great software lists, reviews and summaries.
This is a very ignorant and low effort comment. Let me illustrate:

> Chemotherapy is basically cave man medicine

A meaningless statement. Actually, there is a sophisticated system of diagnosis and staging to work out who needs chemotherapy at all. This includes CT scans, ultrasound, MRI, positron emission tomorography. Chemotherapy agents are modern pharmaceuticals with a variety of supportive care measures to help patients who can benefit from them. How is nanoparticle bound paclitaxel a cave man medicine?

> The idea that we'll basically poison you just up to a point that's nearly fatal in order to kill the cancer is such a terrible way to treat someone.

Again, ignorant. Highly toxic multi-agent chemotherapy is used in acute leukaemias, because the patient will literally die next week or sometimes in a day unless you start treating. In that case you are trying to help someone who is already very sick, so of course there is a high mortality rate, but it is less than the 100% without treatment. How do you suggest we work out the best dose of chemotherapy, apart from giving it at increasing doses and monitoring what happens in a phase I trial? Anyway, many chemotherapy agents are given at a dose that controls disease and maintains quality of life in incurable disease, in direct opposition to your off-hand comment.

> Now I'm not saying don't ever do it -- unfortunately that's where we're at in 2021.

Do you realise that there are malignancies which are 100% fatal without chemotherapy, but curable with chemotherapy? Germ cell tumours in men for example. Acute leukaemias. Lymphomas. Gestational trophoblastic tumours. So what on earth are you talking about?

> It's just kind of unbelievable that cancer remains so elusive that we're still using medical treatments that started from mustard gas usage during world wars, when we're so advanced technologically in so many other ways.

Most chemotherapy agents in use today are not based on mustard gas, for a start. Many of them come from plants. One of the most useful and well tolerated chemotherapy agents comes from the bark the pacific yew tree. Anyway, the argument is stupid - your car engine is based on explosions, so car engines cannot be sophisticated or useful?

> Interestingly, cancers for children are largely successfully treated. I was at a fancy conference a few years ago where some cancer researchers were socializing over wine, and I asked them why that was versus adults. They said the difference was that parents are willing to do almost anything (aka enroll their kids in experimental treatments) to cure their kids, but adults aren't quite so willing for themselves.

This is bullshit. Walk into a clinical trials unit in an adult cancer centre and you'll see. The reason cancers in children are different are because the biology is different, to state the bleeding obvious. Also children are much more physiologically resilient and don't have other medical problems, so their response to treatment is fundamentally different.
A bit disappointed to see this repo doesn't contain the source code for the sound effects. Defender's sound effects kicked ass and were a big part of what made the game experience so intense. Instantly memorable, quintessential sounds of the arcade era.

Williams used the same sound hardware (and many of the same sound effects as well) on all their arcade and pinball games from the late 1970s through the mid 1980s. And unlike other machines that used dedicated sound-generating chips like the AY-3-8910, the Williams sound board was just a 6800 CPU hooked up to an 8-bit DAC. It did everything in software. No square wave generators or hardware timers. The pitch of the sound was controlled by variable-length delay loops!

I spent a bit of time reverse-engineering the sound ROMs a while ago. From what I recall, there were a few different sound-generation algorithms. Some of them generated simple pulse waves or noise. Another was wavetable-based; it used samples in ROM and manipulated them in various clever ways. Another one, which was responsible for their coolest sounds, used a bonkers system of multiple nested loops generating variable-width pulse waves... I was never able to fully understand it...
Sorry if I don't fully understand, I've read through link a bit but it just leaves me with one question in particular: Wouldn't your relativity have to be both different and the same simultaneously for this to work?

In the tachyonic antitelephone example, Bob and Alice send messages that travel at 2.4c, but neither observers are at that speed. Wouldn't the limits of their observation and time dilation cause the messages to appear in order?

If you were to theoretically travel into a black hole, and then somehow escape out of it very quickly, you would see yourself still in the black hole, but you wouldn't see yourself coming out of it, because that light was further from the black hole and thus moving at a different speed?
The miscalculation is often intentional. Manufacturers for example know that Low end EVs depreciate faster than equivalent ic cars but still assign similar depreciation tables because otherwise they couldn’t get rid of the cars or would have to sell em at steep discounts and take immediate losses
Definitely not zero emissions though…
Spent far too much time and money on Defender.

I noticed that Williams arcade machines were better in many ways than others. This applied even more to the pinball machines. There was a quality about them that put Bally and others in the shade.
SolarWind, used in many election ballot tabulation stations.
It seems the more pressing issue is that I will almost definitely question a future pull request to have the author tell me, "well that's what copilot wrote and it looked OK." If I catch it.

I'm all for AI coding assistance, but there's an abstraction layer in between copilot and myself (humans) that scares me a bit. At least an obvious failure prompts discussion and learning.
I’d say if we compare Tesla self driving numbers with human drivers driving similar cars, and count every disengagement as an accident, it would be a fair comparison. Tesla wouldn’t come out looking very good with those numbers though.

Is there any small version that supports it? Like the newest RPi Zero? I can't find accurate info about it
Early/Mid Stage Startups
What early/mid stage startup are you most pumped on right now (<$100M raised)? Think of it in terms of one you’d potentially leave your job for.
There's a book ‘Shaman’ by Kim Stanley Robinson, who's said to do a lot of research for his writing. In one scene of the book, a man goes into a cave to paint such images. Well, when his fires go out, he then spends three days groping around for the exit in complete darkness and getting weaker from hunger, until people from the tribe come in search of him. Meanwhile I imagined real caves as mostly ’in and out’ kind of thing: out of light sure, but not three days worth of crawling.
> Electricity already comes from a lot of sources.

Very true

> It is pretty myopic to think people talking about solar panels means replacing all electricity generation with solar.

I don't think that all will be replaced with solar panels in the future, but considering the amount of energy that is absorbed by earth every second and the available surface area to collect and concentrate it, I think it possible that most of the energy will come from it (solar in general, not just solar panels).

I still think roll out will be slower in some areas and faster in others (mostly due to the incentives of all the different actors and their relative exposure to all the existing infrastructure).

> Solar installations already pay for themselves in under 7 years in sunny areas.

> Peak electricity use is in the summer during the day, when solar would have the most impact and can be double the energy used at night.

Yeah, its the short term time horizon (7 years vs 30 years) for profitability and looking at peak providing capabilities that attracts more projects in the US now (possibly because its a complement to all the existing hydro carbon infrastructure in place that wont be needed when more electricity generation can come from PV and CSP, that others places in the world don't have to the same degree and continue to build out CSP).

> Lol, show me where this anything like this has made money.

Cerro Dominador Project connected to the grid in chile in april this year with 110MW of CSP, so it's making money for someone in the chain (they also have 100MW of PV). Besides, I think nowadays cash flow matters more than present day absolute profitability, something that O&G producers have less of every year as demand growth slows due to higher end user prices and extraction costs rise.

> Molten salt would have to be super heated

That's what happens when you concentrate a large area of sunlight onto a receiver that contains the salt …

> and then enormous amounts of energy would have to be used to move it.

We already use "enormous amounts of energy" to move energy related products…

> Do you actually think that molten salt, with a melting temperature that is double what it takes to start weakening steel as well as being corrosive (https://www.bbc.co.uk/bitesize/guides/zjb2pv4/revision/2)

Not all molten salts are created equal, nor do I think steel will be predominately used in most casing that actually touches the salts with higher delta_k and high heat capacities, UHTCs come to mind.

> is going to be better to transport energy than copper cable (which is already run everywhere with electricity !)

You make it seem like I'm saying that copper cables wont be used at all, where as I don't think it makes much sense over long distances… even now grids need to have power stations every so often in between all the copper cables… power stations that have to consume some source…
There are many different kinds of reactivity... chemical, thermal, shock (e.g. hit it with a hammer go boom).

One of the medicines with the longest history is nitroglycerin (for various heart conditions), which is literally dynamite.
Nah, it's more like a wedding reception -- every Nitrogen atom is just super eager to form an exclusive pairing next.
Fine, then Tesla should not be charging the price of a full battery replacement plus labor for the fix since they are getting a full battery that can be very simply refurbished and then sold as such.
> it just happens that the go stdlib and runtime use "unsafe", so you can't safely use them either.

It's still the job of the code author to make it so you can safely use that code, despite internal use of unsafe.
Apple is threatening to take down my app because of a bogus trademark claim
I own the app called 'Cuff' on the app store. Cuff is a popular 1 on 1 video chatting app, and it has many competitors. One of the competitors is a Chinese owned app called 'Monkey'.

They don't like how I rank for the search term 'Monkey', and demand a monopoly on the search results for the term.

I don't have the term in my keywords or anywhere in my app meta-data. But my app still ranks for the keyword. It ranks for a lot of keywords I don't have directly in my meta-data. I guess because of its overall popularity?

Anyways, they are saying I am infringing on their trademark, and I have no clue what action to take. Apple says they can remove my app if I don't act, but there's literally no action to take.

Do I have legal grounds here? I am thinking if Apple removes my app, I can take them to small claims court to try to make a case for reinstatement, since I am a one-man shop for the app.

It really sucks this is happening. I hate how some random Chinese shadow tech company can make Apple do their bidding in the US, so that American individuals/companies can't fight back. Since they are in China, I don't even know how I can take action against them for bogus trademark claims.

The only action I can think of is to take against Apple.
For level 5 (which Elon promised), FSD has to go tens of thousands of miles without a collision-avoiding intervention. Right now it can't even do 10 miles.

Cherry picking is completely fine because with the limited number of beta users, even a few incidents is enough to show that FSD isn't nearly ready for level 5.

And it's pretty easy to make a car that can self drive on simple roads without a tonne of traffic, so being able to do that without intervention isn't much of an accomplishment.
Current and the Wind
Do you have a right to reasonable charges for damage of rented items? If you rent a jackhammer and break the trigger is it fair to charge the customer five hundred dollars to repair a ten dollar piece of plastic? If you rent a wedding dress and rip a seam should you be expected to pay a fashion designer for the stitching? Nobody would ever rent anything if every object was a minefield of potential absurd over-charges.
Not only did you misinterpret a lot of what I said (including the fact that I wasn't particularly making an argument, but rather an observation and opinion), your aggressive response certainly doesn't invite dialog and is in violation of multiple HN guidelines. I suggest you read them and consider being kinder in your word choice.
The high level problem was the whole mess that Boeing and the FAA forced themselves into by lying to pilots about the plane being like the old plane. This motivated Boeing to solve everything in a sort of clandestine way, which meant there was no proper error handling, and Boeing simply covered their asses by pointing to the runaway stabilizer checklist, which they claimed was sufficient to handle MCAS problems.

This should never have been greenlighted, approved, manufactured, designed. This went against a culture of safety (least surprise, etc) at every level.
No it isn't. The speed of light in SR is not really about light. It's just a good way to explain things.

You can calculate the speed of light from other physical, measurable constants without using light (the permittivity and permeability of free space). Those you can measure with inductors and capacitors. So because those measurable physical behaviours are invariant in all reference frames under SR, it follows that the speed of light is also invariant.
It was intentionally plastic in that they were designing a molded part and chose to not have the nipples a separate part, but molded them in to save on the expense of designing and assembling a separate part.

Tesla really loves to integrate parts together - look up the "superbottle" for a previous example.
Yeah, someone already linked it.

They have no mention of what they are even going to sell the energy at, and no mention storage capacity (if any will be used at all) and not expected to come online for another 6 years.

We'll be able to learn more about it when they actually have an accepted bid from some one.
"VQGAN+CLIP" Text-to-Image Arts on Twitter
A subscription model isn't ideal for a physical depreciating asset like a car. Maybe for software features but having the customer pay outright for the vehicle is more beneficial to Tesla.
Horses do not run into concrete pillars.
AFAICT, GR is symmetric in relation of the direction of time, as are most other important physical theories.

What may add the arrow of time is the second law of thermodynamics: a statistical evolution of a system is not symmetric.

I wonder now how a violation of causality could either circumvent of contradict the second law.
It seems like the hazardous bit is more the fact that this stuff is extremely toxic.
I'm glad that worked out well for you. I have friends who haven't been as lucky. Again, I'm not suggesting don't do chemo, I just wish we were much further ahead in targeted and less toxic treatment options such that chemo wasn't in the picture.
