Why don't electric cars use replaceable battery modules with a standard form factor? Advantages would include:

1) It allows the battery to be easily replaced as the car gets older.

2) With a suitable generic form factor, it would allow batteries to be upgraded as technology changes.

3) It would allow people to only populate enough battery slots for their daily needs. Communing to work: you only need to insert a few battery modules. Going on a road trip: you can buy/rent extra battery modules and populate every battery slot.

4) Matching battery capacity to the task at hand is also safer, as there is less energy in the system in case of an accident.

The manufacturers may be using batteries as built in obsolescence or differentiation, but surely there is enough competition for someone to break ranks and build a car with some modularity. It could stimulate sales by giving people confidence in the battery, the weakest part of an electric car. Maybe Framework should start building cars as well as laptops?

[1] timeanddate.com is a great site that provides a visualization with times and directions for a given city.

I don't think its possible to link directly to a specific lat/lon, so you'll have to choose the city yourself.

For Honolulu the "very good" times are between 2am-6am HST, with the direction about 40 degrees (NE)

We still see heavy use of MD5 in genomics as well. It's effectively used to generate a single identifier that can be used to reference a specific genome assembly. There have been discussions and attempts to move to other, more secure algorithms, but the community and its tooling is too deeply entrenched in using the MD5 for the reference that it would take a herculean effort to change.

I'm personally of the opinion that it doesn't matter. MD5 is fine for genomics. The chances of valid genome files colliding is still extremely low, and there's not really any relevant attack space. Replacing one assembly file with another will just break someone's analysis pipeline, and most likely in a very clear obvious way.

My car insurance is very much higher for a Model 3 than a similarly priced car because repairs are more expensive. This should be added to the TCO.

I like the Model 3 still, because it’s a fun car to drive. It’s not cheap though.
Quantum computers will severely break MD5 and SHA-1, so they'd be broken even if they are used with HMAC. Use SHA2-256 unless you need quantum-resistant collision resistance, in which case you should use SHA2-384. Use HMAC-SHA2-* with an 256-bit key if you want to prevent length extension attacks.

I don't think it's possible on Windows.

It's trivial on Unix - just make the program setgid and change the folder permissions to only allow the group. This can be nested, though that requires that the relevant program be aware of the need to walk through several levels, though often a symlink can hide that.

Note that when creating such a directory setup, `chown`ing away the user requires a privileged helper utility. But you need to make such utilities anyway so the user can delete such directories.

Important note - most other "solutions" only protect you from apps the opt in to security. A proper solution, like this one, protects from all processes running as user, except the process of note.

Seeing as only 41% of road costs are paid for by license + fuel taxes, those EV owners are already paying for more than half the cost of the roads through state/federal income taxes.

There's a fundamental difference between a compiler and a generative LLM algorithm, though. One is predictable, repeatable, and testable. The other will answer the same question slightly differently every time its asked.

Would you trust a compiler's byte code if it spit out slightly different instructions every time you gave it the same input? Would you feel confident in the reliability and performance of the output? How can you meaningfully debug or performance profile your program when you don't know what the LLM did and can't reproduce the issue locally short of running the exact copy of the deployed binary?

Comparing compilers and LLMs really is apples and oranges. That doesn't mean LLMs aren't sometimes helpful or that they should never be used in any situation, but LLM fundamentally are a bad fit for the requirements of a compiler.
Honestly, I'm going to go against the grain here and say that 99% of the time, this is needless pedantry. Yes, these assumptions are technically wrong, but most of the time, let's be real, they're right, or else people wouldn't be able to get away with making them.

Characters are integers, that is a fact. Most of the time, they're a byte, and to be honest, English/ASCII is the most important text setup for computers and it's fine to only support that. For the niche foreign edge cases, Windows supports UCS-2.
Fascinating. What’s “actual AI”?
Asking your thoughts about wrongdoings exposing web app
Hello everyone. I hope you are doing good.
I am sharing with you my app or my idea and I want to hear your thoughts about it.
Here is app: https://sociiity.com

The main purpose of this app is to enable everyone to share any wrongdoing directly with their city.
Many bad things happen to ordinary people every day, and they often feel powerless. But when these incidents are shared on social media, many people see them, and it makes the authorities pay attention. This pressure makes them look into the issue and solve it quickly. If bad actions are made public, they are more likely to be fixed, and fewer bad things might happen because people will be afraid of being exposed.
Lots of crimes get posted on existing big social media sites, but a lot of them go unseen because of a lack of enough followers. It's like shouting in a very large crowd - your voice gets lost. These platforms reach tons of people around the world, but that also means it's super crowded and hard for everyday folks to be heard. You need a lot of followers just to get attention, which makes it tough to speak up.
Sociiity brings this solution. We enable everyone to share any wrongdoing directly with their city. By operating at the city level, we keep competition low, making it easy for users to speak up and share things with others. Our goal is to ensure that everyone's voice is heard.
Currently, I have launched it in my country Pakistan.
If they taught Veblen's Theory of the Leisure Class, then people wouldn't be surprised the gp reaction is the exact goal of Leisure Class.

Through Conspicuous Consumption and Conspicuous Leisure where the keyword is being "Conspicuous" with all their over the top activities, what is really being signaled to the entire chimp troupe is - "you want to be like me or hang out with me then do I what I tell you", "who do you want to work for - the king in the palace with cool toys or someone boring?"

Veblen said using such signalling is important for group formation since people are so different and have different interests pushing them all in different directions. So group formation and cohesion requires leaders who are master bullshiters or people who really believe in their stories.

But the danger is when the leader forgets the point of signalling and story telling is group formation and cohesion. Thats when things go off the rails.
Because batteries last hella long and it's not a particular concern. Nobody's going to be ad-hoc adding or removing batteries in the floor of the vehicle when a longer trip comes up.

Besides, the technology is seeing rapid iteration of cooling systems and integration with the rest of the vehicle (like structural battery packs). This is not the time for such standards.
I’ve test driven most of the competition. They are all much more expensive for a subpar product from what I’ve seen.

IMO the plugin hyrbid market is a much more natural transition and some of those vehicles are becoming very good. The Chrysler Pacifica plug-in minivan is excellent for the price and the BMW X5 plugins are by far the best luxury plugin SUVs that I’ve seen.

You can get good deals on used Pacifica plugins too. Typically in the $20k range.

But we still need a good EV option that is close to $20k brand new.
didnt know that about ipads, i only use apple stuff for work for the last few years. ill look into that!
> Have you been in a train in APAC? THey have LCD screens with status maps on the upper walls... Have you been in a train in the US? THey have pee and poo on the upper walls, and zero map status anyplace.

It sounds like installing screens on US trains would just end up with pee and poo on the screens...
For those having difficulties with naval terminology, seek out a copy of "A Sea of Words: A Lexicon and Companion to the Complete Seafaring Tales of Patrick O'Brian" by Dean King. Hornblower's naval terminology is the same as O'Brian's, and it's great guide to both.

This is where I'm stuck also. I'll probably get a e-scooter as my second vehicle.
I am not sure there are many people who want to swap out batteries when they weigh over 1000 pounds. Inserting a battery would require something to help carry and insert it which makes it have enormous user friction which makes it a non starter for most people. Not many people even want to swap out phone batteries despite those batteries being easy to carry.

It’s the same time everywhere, occurring in the entire sky. You get more meteors on the leading edge of the Earth moving forward in its orbit, so starting at 1AM solar time gets more meteors. You generally stop being able to see them when the sun rises. All you need to look up are the peak days.

“Everywhere” excludes the poles though, things get a bit wonky above 80° latitude.
They do definitely limit upvoting/downvoting from similar accounts, so this isn't out of the realm of possibility. They care to avoid false votes, voting rings, etc.
We have a cheapo Subaru and just use those collapsible silicon buckets, a sous vide, and a cheapo Amazon pump+shower combo. Entire setup is less than $120 and now we have a sous vide too.

You can run the heater off a battery bank (we have an eco flow with the panels). Much easier

Also, towing and road trips are like the number one reason I think most outdoorsy people should be going for plugin hybrids for now. You can be 100% clean (local utility dependent, limited to 'fuel' and not other maintenance) for like 95%+ of your trips but still have that extra oomph if you need it
just how cheap do you expect that to get to? right now a model s has a 90kwh battery... that's almost 9 grand to replace in 2025. there will be a floor to this and i don't think it's going to be that cheap. gm et. al. are looking into 200kwh batteries reasonably soon. that's almost 20 grand to replace or the cost of a small ICE car.

We've got a 2005 CR-V and a 2015 Nissan LEAF for our 4 person family and it's pretty ideal. There are enough days where we both need a car (often because kid #1 is doing X at Y and kid #2 is doing M at N and we need both cars to get both Y and N).

The LEAF gets the bulk of the random nearby errands and still has ~70 miles of range (62-65 in winter). Our total insurance is $1220/yr for two cars, two drivers, and substantially higher than standard coverage limits. In 9 years and 25K miles, the LEAF has needed wipers twice, washer fluid, one tire plug, and is about to need 2 tires. That's ideal for the guy who turns all the wrenches on the family car. (The Honda is low maintenance, but the LEAF is nearly zero.)
They probably use stanard cells. However modules don't make sense as they need to pack cells where they fit and that goal sit in conflict with a standard module.

Speaking of that, if you were ever curious how computers do floating point math, I think the first Oberon book explains it in a couple of pages. It’s very succinct and, for me, one of the clearest explanations I’ve found.

The annual NIH budget is >$50B and they earmark large portions of that for specific problems. This has paid off well for the US which became the world's leader in biotechnology and has maintained it for some time. NSF is another $11B, DOE another $50B (part of which is military, I admit).

Those only have a limited dependence on dozens of senators; the NIH typically gets most of what it asks for every year. The US has funded science at spectacular levels in a bipartisan way for some time (that may change in the future). Of course there is still a lot of political bargaining, I'm not going to deny that.

What's interesting is that we could clearly spend even more if we felt it was a priority. There's so much that could be taken from military spending without having a direct impact on our defense. But I don't think we want to do that; during my grad school career, the NIH budget almost doubled, which led to a huge bolus of grad students minted as PhDs, who then had no jobs beccause the size of faculty positions didn't change nearly as quickly.

I admire China's efforts and I see a lot of similarities in China to the US around 1900: the time when the balance of industry and technology shifted from EU to US, but growing your industry super-fast runs the risk of overheating and meltdown.
I've read all of Hornblower many times, starting in elementary school nearly 55 years ago. I've not read O'Brian at all, though I loved the "Master and Commander" movie.
We don't usually hear about plagiarism accusations in the news for weeks at a time. There's a particular reason these scandals came up at all and became a major focus for the national news.
Charge at the house. I haven’t done the math recently but when I had a Chevy Volt the electricity cost was equivalent to about $0.64 / gallon of gas.

It is fun to drive though.
It's probably my own biases, but I feel like the community is going to be a lot more reliable and motivated to publish information than the organizations which are scrutinized by that information being public.
This seems rather amateur hour. Do satellites not undergo rigorous testing to ensure they're operating within constraints?

I've done plenty of consumer electronics in my day and leaking around 144Hz is frankly unimaginable at any scale above a toy. I'd love to see a post mortem on this one.
I kind of agree actually on your cost points. It’s still a luxury purchase. I am a bit more conservative of a saver but feel priced out and sadly went ICE.

If you qualify for the EV tax credit, I would argue the car is too expensive for your budget.

If you don’t qualify barely, a brand new ICE vehicle is going to last years and be cheaper. Is it really worth it to push budget?

If you way don’t qualify, definitely buying an EV. Also congrats on your income.
Thanks, this worked well for me, too at about sea level and about 60 degrees in my home. I was wary because of the cook time - I usually only need 18 minutes for a French loaf at that temperature. I did get more rise than expected during baking so my shallow Dutch oven cover smooshed it a bit but I have a deeper Dutch oven I can try next time.
The article talks about range concerns as if they're simply incorrect or ill-founded:

> Niedermeyer said that while an electric car can meet most people's driving needs, it struggles with edge cases like road trips because of the need to recharge. Since Americans have been promised a one-to-one substitute for their gas cars, this seems like a failure; an EV should be able to do everything a gas car can. This idea persists even though in 2023 the average US driver traveled only about 40 miles a day, and in 2022 about 93% of US trips were less than 30 miles. Still, in a survey conducted by Ipsos last fall, 73% of respondents indicated they had concerns about EV range.

93% of trips are less than 30 miles, but the vast majority of drivers take occasional trips that are beyond the range of an electric car. It's no wonder that 73% of drivers have range concerns-- no one is concerned with the EV getting through their commute, they're concerned with the EV getting them to their distant family / weekend trip / vacation home / etc. The argument is a clear strawman; it's playing down what people have genuine concerns with and focusing on the range aspect that's obviously unimportant.
Woah! I love Neptune’s Pride, thanks for the game!

While in college, I stayed at a hacker house airbnb over the summer with a bunch of newly befriended tech friends, and I got us all playing. I have fond memories of changing the trajectories of my ships as soon as people went to bed, double-crossing alliances. Good times.
Then don't compile it into machine code? The problem is in application development, not low-level programming. If a random person on the internet makes an application, there's a non 0% chance it's malware if you try to run it. It shouldn't be that dangerous. It's ridiculous that it still is that dangerous after decades of desktop computing and the only way to avoid this is anti-virus heuristics.

All we want is to get rid of the possibility of an application developer including evil code.

We could have a fully interpreted language layer running on a platform that never lets application code touch the file system. How do applications do fast stuff like GUI then? You just have a package manager with libraries that can do low-level stuff but are vetted so they don't expose APIs that let application code interact with the file system. That way in order to exploit an user's computer you need to exploit a flaw in a library thousands of other programmers use instead of just importing std io.

A lot of security seems geared toward server environments where you are only dealing with code you fully trust in, like the left-pad library. If bad code broke your server, you could really just load a backup. But most of people using computers are on their personal computers, a majority of them have no backup, and they are downloading and running random programs all the time. It makes it harder for both desktop application developers and their users if there isn't a sandboxing layer in the middle. It's probably one of the factors that is killing desktop apps in first place since most users can trust a website that is an image editor but fewer would install an image editor because it can contain a cryptominer, or a ransonware, or a virus, or whatever.
