VW is betting hard on EV cars - I guess that German goverment will cooperate and will invest heavily into EV infrastructure ...otherwise it will be huge failure.

VW will finally solve problem with other brands within VW group - Skoda and Seat are sucessful brands and often cannibalize VW models (Skoda Kodiaq vs VW Tiguan, VW Passat vs. Skoda Superb etc...). VW presented recently strategy for next few years where they said that Skoda will become 'low-cost' brand and Seat will be more 'luxurious'.

Skoda is allowed to have only 2 EV models in next few years - minicar Citigo and Octavia (midsize sedan/combi), nothing else will be allowed (except few hybrid models) so it will be easier for VW brand to become EV leader in EU in next few years.

Also in the case there will be crisis VW will throw it's cheaper brands 'under the train' in order to survive :/
I'm asking genuinely.

No, parent answers the question, "What is the difference between the git tree and a dist tarball?" Which is self-evidently (and unhelpfully) "you don't need autotools installed with the dist tarball". My questions are: Why does this difference exist? Why would you not track everything necessary to build a library in git? How is the dist tarball built differently than just zipping the current git tree?
I think you are probably right, this does not seem optimal, it doesn't even seem that they recognized the class of problem that this is? It seems like they are attempting to use a greedy algorithm on a problem which very obviously has local extrema.

I personally just hate leetcode for largely subjective reasons. Its problems tend to be poorly specified and uninteresting compared to the other places, editorials are spotty, and there's too much push to pay for a subscription for my tastes.

Inflammation is part of the immune response. It's not a cause, it's a symptom. And much like other symptoms like vomiting or fever, the symptom is actually an effective way for the body to fix root causes.

Being in a perpetual state of fever, vomit, or inflammation is clearly an unhealthy state, but that doesn't mean suppressing these symptoms is useful.
As a native French speaker who knows how to do that without knowing the rule, an American friend once told me how they remember where to put the adjective: B.A.G.S.

Most adjectives dealing with the following will precede the noun:
- Beauty
- Age
- Goodness
- Size

It's not always correct but it's a good start...
How hard would it be for them to instead reverse lookup the outbound socket IP addresses to determine the servers to which you are connecting?

Assuming they have some people performing the same DNS lookups from similar locations I bet they could construct a good enough mapping. It’d probably be even more accurate if there’s DNS caching client side as it’d count actual connections and not just lookups.
Until you listen to his actual content and it is, the vast majority of the time, pretty "easy" listening in the sense that it is pretty vacuous and doesn't really require any sort of concentration to follow along. Don't get me wrong -- I listen to it often on my way to work, but one of the reasons I do is because it is not something that really requires much of my concentration to follow along.
Docker containers for integration testing with jest
It's a step in the right direction, but it's not as good as it could be, because it's hindered by compatibility with unix.

A native process on its own can't do much harm. Only with syscalls can it access other processes, the network, hardware, files, etc. Executing some random code shouldn't be dangerous.
I'm sure it was, I'm just not so sure that it does a very good job at that.

I feel like the most obvious interpretation of this is "APT41 possibly accessed billions of devices" which is incorrect, they had the ability but it is known that they only accessed a rather limited set of devices.

The problems with permissions dialogs are overblown in my experience. You get hit with a flurry at least initial boot up after upgrading because desktop applications don’t know how to behave themselves in a sandboxed environment and just reach for whatever they please, but after that initial burst they’re quite rare.

With how Apple has been gradually weaning third party devs from having extensive/root access it’s nowhere near as annoying as UAC was.

Normal weed "flower" is 10-30% THC. So 1 gram of weed is 100-300ish mg of THC. A single prerolled joint is usually 1 gram of flower. So this dose is around 1 joint.

Edit: importantly this info is for smoked flower, edibles and concentrates are a little different because of how they are absorbed.

> Organic farming absolutely uses pesticides and herbicides. In fact they often must use more of it and at greater frequency than conventional farming methods because the organic variants are inferior.

Got a citation for that? I've always been under the impression that organic farming by definition doesn't use pesticides and herbicides, and that's why they're more expensive. The yields are lower because of some crops being eaten by insects, and quality is lower due to having to battle weeds devouring nutrients from the soil. Is this not accurate?
In 50 years time, someone on this list will be mostly (or at least directionally) right in their predictions. If they are still alive, they will be lauded as a savant and sage. The more outlandish the 2019 prediction was, if correct, the more recognition they will receive.

And thus all we will actually learn in 50 years time is that human nature changes very little. We will still retrospectively reward success based on chance alone, not distinctive insight.

In short, statistics will continue to be an underappreciated practice.
Tesla builds ~400,000 per year out of a single factory. If VW were producing 3.2 million/year by the end of 2022 that would seem like a lot to me.

Of course, if/when Tesla ever builds a European plant it may be much smaller than their current footprint. That isn't uncommon for Europe, so if I had to hazard a guess, the VW plants will average less than 400k/plant as well.

Even going from where they are to 2 million per year over the next few years would be a great accomplishment, though. And that certainly seems feasible, if not necessarily likely. ICE companies have an even worse track record than Tesla at keeping promises on electric vehicle schedules.

Speaking of registers and CPUs, the PDP-10 was interesting (at least, the KA10 model...not sure if the KI10 or KL10 also did this).

The architecture included 16 general purpose registers, which were addressed using the same address space used for main memory. Word addresses 0-15 referred to registers, and addresses 16+ referred to core.

The interesting part is that the registers were actually optional! If you wanted to save a little money, at the cost of some execution time, you could order your PDP-10 without registers. Because the registers and memory use the same address space, everything still worked with the first 16 words of core taking the place of the registers.

If you ordered your PDP-10 with the registers, they would in effect replace the first 16 words of memory.

Main memory was magnetic core and the optional registers was semiconductor memory, which were much faster than core.

Since the registers and memory shared address space, it turned out that you could execute code from the registers. You could often gain quite a bit of speed in a program by having it copy the code for its inner loops into the registers and running from them.

Again, this is about density.

If you imagine an urban core in the center and a disk of suburbs around it, the availability of housing rises with the square of the radius from the core, and the cost of providing a rail/bus line to the core will grow with the square of the radius, but the cost of giving each person an individual vehicle grows with the population. So there is a density in which personal vehicles make sense and a density in which rail lines make sense, and this trade off is determined by the relative cost of providing individual cars versus rail lines. But because of this squaring effect, it's always the case that at some distance from the radius you need personal transportation.

While Holland is notable for its bike usage, it has 440 cars per 1000 people, or more than 80% of households own 1 car even in Holland, and 30% of Dutch households own 2 or more cars (See Figure 15, https://repository.tudelft.nl/islandora/object/uuid:a33eb3a5...)

Now maybe in the future there will be a fleet of self driving cars that you can call up -- who knows? Maybe electric bikes. There are many options, but density remains key in this trade off, and it's important to realize that different households have different circumstances.

I don't own a car, I live in San Francisco, but I realize this is because I am rich enough to live in the more expensive urban core, and that I am wealthy enough to be able to walk to stores staffed by people who are earning less money than I am and have to drive into the city in order to serve me coffee, food, alcohol so that I can just walk to their business. I am also dependent on goods being trucked in from far away so that I can walk up and buy them. So, it would be a bit inconsiderate for me to tell those people who can't afford to live in the dense core that they need to do without their cars and share my lifestyle. They are doing the best they can under the circumstances.
How to Reach Female Solo Travelers, the Biggest Market in the US
My wife spent months in the hospital due to Hyperemesis Gravidarum (a disorder during pregnancy that causes continual vomiting and nausea. My wife vomited up to 40 times a day, eventually vomiting blood and breaking vessels in her eyes. She survived on a banana bag and lost 20% of her pre-pregnancy body weight. She said HG feels like being on an unending roller coaster while you're hung over and have the worst flu of your life). We lost the first baby. The second pregnancy was only survivable due to cannabis. It was risk we knew but 7 years later our child shows no signs of developmental disorders. I know, N=1, but still worth sharing.
What do macros do that functions don't?
It seems like they are attempting to use a greedy algorithm on a problem which very obviously has local extrema.

Yep. You'll end up with a lopsided allocation, with one or two allocations holding a very large percentage of the total allocation.

Distributing the allocation weights could help, e.g. with ensembling, regularization or some other kind of penalty.

I don't have a lot of faith in common sense, no matter whose it is. Especially when dealing with large numbers, large populations, diverse human behavior, common sense is rarely common and frequently wrong. So yes, a citation is needed.

> I don't see how helmets preclude cultural adoption.

Case in point. It seems completely common sense to me that helmets are a massive barrier to widespread adoption! Leaving aside the issues it introduces with bikeshare logistics, having an additional thing to keep track of and carry around and periodically replace (helmets can go bad!), here's something that I suspect you may not have considered: women! Whether it seems reasonable to you and me or not (and I'll be honest, it doesn't seem reasonable to me), the 2 reasons every woman I've ever asked gives for why they wouldn't want to use a bicycle to get around more are

1) sitting on the seat is awkward/uncomfortable when wearing a skirt or dress

2) helmets would ruin their hair

Requiring helmet wear makes cycling a nonstarter for a large chunk of 50% of the population (how I wish I had a citation for this! as far as I've been able to find, nobody has done any kind of survey that attempts to figure out if this is as widespread as I've observed personally). This alone makes me opposed to it, never mind the exaggerated claims of helmet efficacy
I've been using TheBrain (https://www.thebrain.com) for ~10 years now and haven't found anything that comes close to it in terms of flexibility. If you haven't looked at it in awhile, it's worth checking out again. They have a new desktop app, much better mobile apps, and even after all these years, development continues steadily.

I've got 16,399 thoughts in mine and add more just about every day. Anything I think I may want to know later goes there. More ephemeral notes go in Apple Notes (I used Evernote for a long time but became annoyed with their business model and haven't missed it). Everything else goes in The Brain.

Search great, the ability to link notes as parent/children/siblings is extremely powerful once you get the hang of it.

It's not free, but it is, in my opinion, easily worth the cost.
I'm surprised that 4NPS gives even a mild benefit to bandwidth (maybe 13% or so), given that the central IO die handles all communication anyway. You'd think that with the architecture here, there'd be no real benefit to splitting the RAM channels.

I develop Flowx [https://www.flowx.io], an Android weather app. It makes around $2,500 USD/month with about $500/month in costs excluding my time. It covers about 60% of my total costs including my time which is 40+ hours a week. I cover my remaining costs through contract work. This might not seem like a success but the business allowed us to move to the Rarotonga, Cook Islands from Auckland, New Zealand. Lifestyle-wise and building-a-business-wise, I think it's a success.
I'm planning to buy a new car in two years, and I'm really excited about the possibilities of electric cars then. What I really want is a mid-sized hatchback, with interior form similar to my current Subaru Forester (and a zillion other similar light-duty quasi-SUVs). It's such a popular form factor, and Tesla isn't there on it.
Of course, I don't intend to say that vista had anything that comes close to the modern day sandbox. However, it did enforce strict security policies that its predecessors didn't have. UAC and up to some point smart screen is comparable to the sandbox permissions and the notarising thing. It's an inconvenient break in compatibility, dialog flow and program design that has a lot of benefits and some downsides. Until programs adapt to the new paradigm, old programs will likely be slightly annoying to use, just like what happened in the Vista days.

I hope Apple doesn't solve the dialog problem the way Microsoft did though (by sacrificing security for usability), now we have the situation that being logged in as a local admin with UAC set to default means that any malware can gain admin privileges through UAC bypasses. You can prevent this by setting the UAC settings to max or logging in as a standard user, but then you get Vista-style annoyances again...
Bike infrastructure IS car infrastructure for the most part. Also, auto drivers pay the exact same taxes that bicyclists do and additionally pay greater taxes in gas and licensing. Bicyclists always like to whine “Share the road.” It’s time they share the costs as well. Fortunately, there appears to be a push in my community to make that happen and I think it is great.

Now, if you’re talking bike trails, then yes. Those are cheaper. If you’re advocating that bicyclists should be limited to bike trails, then I’m in full agreement. If they’re on the roads, however, they should be forced to pay all the road fees cars have to pay.
> Apple has finally reached their Vista point

Well, on a different note, even Linux desktop/workstation distributions have reached their Vista point... in the somewhat trivial sense that they now need Vista-capable hardware in order to be reasonably usable! (We do know how it happened, it's all about the usual CADT syndrome. At least they are still usable, unlike Vista or Catalina. But one can still be disappointed by such developments.)

I am involved on the theory side of the implementation of different kinds of solid state qubits, so you may say I'm biased, but the question really isn't whether we will ever get it or not, the question is when. We already have had exponential growth in single qubit coherence times in the past decade, we have very good entangling gates, and there isn't any fundamental reason why the number of qubits can't be increased. It's not like there is an invisible great barrier ahead of us, and nothing in the physics of these devices say we can't.

By the way, they aren't using quantum error correction methods right now, basically because it's not worth it: you need a lot of physical qubits to encode a high quality logical qubits.
