I'm really curious to see how electric cars work for the poor (maybe 25 years from now, not presently).

One of the big selling points of electric cars is simplicity - with far fewer moving parts, less can go wrong and you can hopefully expect a car to last longer.

That's the hope anyways, but the big maintenance item in an electric car is the battery, and of course that's an expensive thing to replace. Will folks be able to do DIY repairs like cobble together battery packs from various sources? Will a decades-old battery that is 50% depleted or more still allow that car to function properly, just with less range? Or will it refuse to "start"?
> Hand the operation & maintenance out to some company or whatever, there it's possible to compete.

Oh no. Construction, operation and maintenance of electricity and other vital networks (water, gas, sewage, telecommunication) should be done by the government as a government agency with a quality of service mandate and not in form of a profit-oriented company no matter if government owned or private owned / publicly traded - because "competition" and/or a focus on costs is always going to end in price and wage dumping, cutting corners and sometimes in deathly disasters (California fires caused by cutting costs on maintenance, Flint water scandal, Texas infrastructure collaps due to un-hardened systems, ...).

I guess it's a learned dexterity thing.

:wq = <move finger of right hand to Shift> <depress Shift> <move finger of left hand to ;> <press-release ;> <release Shift and move finger of left hand and press w and q>

ZZ = <move 2nd finger of left hand to Shift> <depress Shift> <move index finger of left hand to z> <press-release z twice>

As someone with mildly poor dexterity (and I don't touch-type with all my fingers, I mostly use my index fingers), the second approach looks somewhat more interesting to test.

Yeah and that is by design. We consider famines as simply unacceptable and thus we make sure that the agriculture sector works, even when it shouldn't. Compare that to countries who are dependent on food imports for basic nutrition. They simply aren't doing nearly as well as the EU or USA.
The "deregulated" energy industry is built around that exact principle you're talking about, both in the US and the EU. The "platform" is the grid, which delivers electricity from plants to homes and businesses. Because competition in this area is limited, these companies are regulated monopolies, whose infrastructure decisions and rates are closely supervised by a government energy board. These entities work as part of a regional transmission organization, a highly regulated entity that ensures stability of the grid as a whole (https://en.wikipedia.org/wiki/Regional_transmission_organiza...).

Generators and users of electricity operated on top of that platform. Generation is a competitive market--many entities can be delivering power into the grid, and the product is fungible. Users don't care where the electricity comes from, just about the price. Electricity generation is therefore quite suitable for market mechanisms.

What happened in Texas was not an example of a privatized "platform" failing. The platform (the grid) was fine. Instead, adverse weather events caused a shortage of the product (electricity) running on top of the platform. Put differently, this is not like a scenario where Texas decided to privatize roads and things went sideways. It's like a scenario where packages didn't get delivered on Christmas because COVID caused an unexpected spike in demand for package delivery, as well as an unexpected shortage of drivers for delivery vehicles.

The biggest wart for me is the complexity introduced by language extensions, many of which can significantly alter the behaviour and feature set.

There is not one Haskell, there are many flavors of Haskell, and every file can be a different subset because extensions can be toggled by file ( `{-# LANGUAGE <Extension> #-}` ).

My second biggest wart is the heterogeneous nature of the ecosystem due to lack of established paradigms, and the heavy use of complex type system abstractions in some libraries (plus the common lack of good documentation).

I love Haskell as a language for the learning experience, but I would not use it in a professional/production environment.
The machine learning team is responsible for all search and discovery features that users engage with when searching our inventory, some of the highest traffic, uptime demanding services I’ve seen anywhere in my 15 year career. We also run all of the image and language processing that occurs in real time in the image editor post upload, along with a HA queue system that aggregates requests to route them to shared GPUs on the backend. In our case, many machine learning systems are on the critical path for customers, and we have a significant platform team within machine learning specifically to ensure we can support this, meet uptime demands, design auto-scaling solutions in our on-prem data centers, execute failover and disaster recovery (and drills to simulate these) and more. And so does every other team.

Earth to Techies: Let’s Map It All:
Imaging the world down to the meter will soon spur a navigation breakthrough.
By Andy Kessler

"To make nuclear bombs, you float a gaseous uranium compound down long distances until molecules with the heavier U-238 isotope fall away, leaving only highly fissionable U-235. That’s why during the Cold War the U.S. flew U-2 spy planes over the Soviet Union to film the ground, so that analysts with lightboards and magnifying glasses could study photos looking for long, narrow buildings. And you thought your job was tedious? We’ve come a long way. But that was a while ago—what’s possible today?
To find out, I recently spent some (Zoom) time with Dan Jablonsky, CEO of Maxar Technologies, a Westminster, Colo.-based satellite and imaging company that, as far as I can tell, is the state of the art.
Circling every 94 minutes, Maxar’s satellites survey 3.5 million square kilometers of the Earth every day to capture images that are accurate down to a meter and are stored in a massive data set. Each satellite’s camera can be swung up to 50 degrees from overhead. Maxar has 17 years of imaging history. It stores 120 petabytes of data on Amazon’s servers."

Well, showing up to work for someplace that did this used to be called "scabbing" and carried quite a bit of social stigma. But yes, this requires wider organization and some regulation. This type of organization and regulation do exist in many places in the world, and can work decently well.
I try to write it in "PHP style", meaning just a whole bunch of "my $someVariable = SomeFunction()", and as little as possible of "=~ /^#^$^&*&/ <> ;~;"

It helps that I try to build and maintain two versions of the same codebase, so I tend to write in a language which is the lowest common denominator of PHP and Perl.

I'm at a modest 14K lines now, and still find that I can find what I'm looking for with just a global text search...
I'm not sure this adds much to the original thought experiment. Correct me if I'm wrong, but the idea behind Maxwell's Demon was to illustrate the notion of adding information to the system to prevent/slow entropy (information being the decision to swing the trap door one way or the other). This article just seems to describe a physical device that sort of approaches that.
The helicopter project is somewhere said to cost $80 million.

Would be interesting to know cost allocation for that Sony/Samsung chip. Project manager and scientists/engineers could have listed design challenges for industry player like TSMC/Apple go beat with an offering, a short run of 20 chips specifically for this helicopter.
This is a great write-up, and as someone who spent time being poor-ish, it really resonated.

What I realized from my own life experience: the US sawed the bottom rungs off the ladder in the 1950s when it suburbanized. There is no affordable housing or transportation in 95% of the North American land area, and virtually every societal problem we deal with either stems from this or is made worse by it. Then the healthcare disaster is the cherry on top.

The US is a great place to live and work with tremendous upward mobility —— but only if you can stay above the event horizon which is reliable car ownership and insurance coverage (health, home/renters, auto). If you fall under that, you will need help or a lot of good luck to get back out.
I bought a webcam and started to hangout on Omegle. Seems crazy right? It used to be a site where 70% of the people have their cock out on camera, but since the site added a “Nude” section, the main section is 90% people just wanting some casual talk. There is the occasional exhibitionist, but Omegle’s new AI auto-ban system is pretty good. You can also just skip them.

I’ve met cool people from around the world, including people who I’ve linked up with online and played online games with. I recommend it to everyone. On Saturday nights my girlfriend and I will get on cam and just talk to people and listen to music since we don’t want to risk going out.
Everything north of Hong Kong Island was going back to China anyway, under international law. For the UK to oppose that, without China's consent, would be below par for their standard of international politics.

Hong Kong Island is 80 km^2, surrounded by undisputably Chinese territory and waters. Most of it is mountainous rock you can't develop very much. Not even the airport lies on the island, and there is less than 1 km of sea between the island and territories returning to China anyway.

The Inferno operating system released in 1996 does this.

It was designed to run on anything from light weight mmu-less bare metal embedded with no graphics to full fledged PC class hardware. It included a hosted mode where the kernel is built as a program that runs on plan 9, unix, unix-likes, and windows. The kernel is a vm with no way to implement native code unless you add it to the kernel.

Since everything runs in the dis vm you can have a truly portable os where the same program that runs on a headless embedded mips box will run unmodified in hosted inferno on an x86 Linux machine. Unfortunately it does not yet run on x86-64 due to dis having hard coded 32bit constraints. However, someone is actively working on that little issue.

Serious question. Humans have been dealing with domestic dogs for 10's of thousands of years, as work partners and companion animals. Obviously there should be some common methods that have been successful during that time, so why is it that every decade or so we have "new methods these days", instead of having a set of proven methods over the last few millennia (whatever those proven methods end up being)? Why does best practices with dogs seem to change quite a bit on the scale of decades?
Oh, I see: You're saying they use data from Phase 1 to try to infer how many doses would be best.

That does make sense, but it must be pretty far from an "exact science".

To my (rather recent) understanding, all vaccines benefit from a booster dose. Because that's how the human immune system works.
> Interesting to see how in the past two decades, activist hackers have swung from far-right to far-left.

I wish this was the Mandela Effect but it's just garden variety propaganda telling people the far-right are taking over and literally changing their memories. ie Anonymous was far bigger than GNAA and GNAA wasn't far-right.

Not agreeing with his points, but funnily enough, I think Sony does use Azure.
If you have beefy objects representing, say, characters, and you only care about their position, you'll use 16 bytes of a 64 byte cache line. So for the "move everything to the right" use case you're wasting 75% of the bandwidth if you go with simple composition or inheritance. If you move from arrays of objects to objects of arrays, your cache utilization improves fourfold. This doesn't matter for your character of, IDK, 20 platforms moving on the screen, but it does matter a lot for entities that are counted in hundreds or thousands. There are only that many cache lines available and memory bandwidth is also limited. If it's your bottleneck, ECS is going to potentially solve some problems. If you're doing something simpler it may not matter at all.
In the US, there are sharp race and class disparities here: if you’re white and pass for at least lower middle class, you are much less likely to have an issue because even unethical landlords know the police and courts will listen to complaints. Go outside of those communities and complaints become more common, often with accounts of a rental company caving immediately after someone demonstrated knowledge of their legal rights and lack of fear to contact the justice system.
Had the same experience while learning scheme. Lazy eval, continuation, continuation-passing-style, coroutine, OOP (yes!), lambda stuff, dynamic/lexical scope, closure, thunks, tail recursion (not all of that is specific to scheme of course, but you get the idea)...

Generally speaking I'm on your side - but here? No. This case is an incentive for future shareholders of electric utility ops to keep their company accountable for disaster preparation, so that the shareholders don't lose their investment.

> It does not help to call all differences as only racism. The truth is differences are caused by a variety of reasons, of which racism is one.

This is where the neo-liberals fall down. They like to blame, or over-blame, racism for all the world's ills as it has the convenient side effect of allowing them to sides-kirt any / most of the blame.

Not really. You could be pulling down $500k a year but have such a high spend rate that you frequently run out of money before your next paycheck.
As I become more wealthy, I have started to tackle problems that I never really thought about when I wasn't as well off, things that cropped up when I thought I'd finally have peace of mind. In retrospect, the insecurity was always there, but I had the luxury of ignoring it when I was poorer.

Once I started making enough not to worry about rent, the problem was then saving enough for things like retirement, setting up tuition funds for the family, etc. Now the problem is managing my mix of investments and having a big enough pad to insulate myself from the occasional recession. But, I think even if my net worth were to triple there isn't really anything I can do to avoid a great depression-level economic catastrophe. Beyond that, I know not what money problems people with eight or nine figure net worths are scared of but I would assume if I ever made it that far the anxiety won't go away.
What I have learned from teaching Data Science at the University
>It may also push prices up

It doesn't look like the EU care if prices go up. They are more concerned with waste then consumer rights. Also, let's say a microwave now cost £50 and lasts 5 years. let's say the price under the new laws goes up to £70, 2 things will happen; a) the consumer will be more motivated to get his machine fixed and b)the microwave will last 10 years, ultimately saving £30. My math may be badly wrong, feel free to correct me. I just plucked all those figures out of thin air.
I do admit, given a choice I would rather program the 6809. I loved the 6502 and it was the first processor I learned assembly, but I still think the 6809 is better.
I still think the meanings are distinct. For instance, you could say: "I can't get a home loan because I'm poor", "I qualify for food stamps because I am poor", but attributing these things to being broke sounds a bit funny. By the same token, you wouldn't say "My grandparents grew up broke, but became middle-class"

>but it will certainly cut into SpaceX's cake once it is online.

Doubtful. And that isn't a knock against Rocket Lab, targeting a different niche is smart business, but still doubtful. Because the target of any rocket under development right now that wants to directly compete with SpaceX can't be F9, it needs to be Starship. The fundamentals along with the iterative capability and in-house demand built into the core of the design plan indicate they're going to be about to push costs below $200/kg and eventually even below $100/kg, along with enormous other sets of capabilities. That will represent just a mind blowing paradigm shift in cost to LEO, and SpaceX will probably want to retire F9 completely as soon as they're done with contracts and SS/SH is fully certified.

Rocket Lab should still be able to find a healthy market, like now, for customers who want specific orbits and times for smaller payloads that don't line up well with ride sharing on a big rocket. But it just won't be in the same market slice at all. Which is fine! The entire space market is set to grow a lot, no zero-sum games for a good long while, and in a growing market there can be room for many players to grow together. But everyone not on the leading edge is going to have to stay nimble.

I’m also GLAD they copied the Falcon 9 design (which is as old as scifi and was demonstrated by DC-X and Masten Space Systems and Armadillo Aerospace) for the first stage landing concept. Better to use what works instead of just making a novel approach just for the sake of novelty or Not Invented Here. Rockets ought to land on a pillar of flame like God and Heinlein (EDIT: and apparently the Soviet Cosmists) intended: https://youtu.be/TdSxDNnqRlo

Also, RocketLab has a TON of ex-SpaceXer employees... I’ve long said that the high churn (for aerospace, but not any higher than typical tech company) of SpaceX, while not necessarily really good for SpaceX, is really good for the industry as a whole.
