This warning is very important. It’s absolutely not expected that generating tests means executing module code, side effects and all.
You don't need some special charger. I charged from a normal wall plug for ages until I paid an electrician to upgrade it (and even then it was only an upgrade to a 15 amp circuit). You'll recharge fully overnight without any trouble.

What you'll end up doing is just buying one of those outdoor-rated extension leads that you can find in a gardening store and running it under the garage door out to where you park the car.
Play the Atari 2600 with a laser gun
That's not much of a prerequisite.

My first programming class when I was in high school in 1998 had, as one of its in-class assignments to invent an algorithm for sorting an array of numbers and implement it in BASIC. I think most of the class, never having programmed before that semester, did just fine (though good nlogn solutions were not abundant).

That said, I agree that this is probably not the _very_ first book to read to learn algorithms and data structures, as some of the simpler earlier ones seem not to be included.
It's already live in Greece (I just issued mine). The current government has taken the national bureaucracy from the stone age to the space age in something like three years. We used to have to go to the various services' offices to get whatever certificates we needed, then around a decade ago another government created dedicated physical services for certificates, validation and other such daily work.

This government has created a website where all certificate issuance and most other government-related business is fully electronic, I kind of can't believe they've done such a good job for such a backwards country. I'm amazed.
Data locality is just one of the things needed for writing high-performance code. Another thing needed is to have more development time for performance optimizations. C++ developers spend significant amount of time for manual-memory-management related bugs. Developers in languages without manual-memory-management can spend this time for performance optimizations.

And regarding "Java will never be as fast as well-written C++ code." => since Java is getting inline/value/data classes [1] is will also benefit from data locality.

> Maybe you don't need that much of a grid update at all

Besides the tons of batteries that are needed?

> if you consider that you car could power your house indirectly using solar power

Well besides the times where you drive your car.
Also the car's batteries wouldn't last very long due to constantly being cycled.
"Incels, a subculture mostly composed of young men"

yeah...that's certainly _a_ way to describe them. haha.
The article didn’t resonate with me at all either, but I think it’s mainly because I don’t fit into the collective “we” the author talks about.

> We apply to hundreds of jobs. We swipe on hundreds if not thousands of people on dating apps. Many of us are like me, and perpetually have an infinite loop of notifications on an infinite loop of communication apps.

Naturally if you go head first into potentially thousands of interactions, there will be a lot of rejection.

To me, friends and social media are separate concepts, but I understand that most mix the two.
I can't help but think that for every student more into drugs/sex/drinking/clubbing, there is a kid out there who was genuinely interested in studying from the top academics that probably didn't even bother applying because they thought they wouldn't be able to get in (or won't be able to afford it).

I am also surprised that the culture you describe seems to be tolerated at best and even encouraged at worst. Sure, it would happen anywhere, but it is surprising to me that it is not strongly discouraged in society overall and at top academic institutions in particular.
I remember in university I lived in a house with 8 people. We would all gather for dinner, often with a few extras from out of the house. It was such a wonderful feeling (and wonderfully efficient, you only had to cook once a week!).

The idea of communal spaces needs to come back. I don't think it would be too hard for a 10-story apartment block to offer a communal area, especially as the shops that were often on the first and second floors are going out of business due to online shopping.
We have more opportunities to interact with more people from all walks of life from all over the world in a way that is unprecedented. Marginalized groups have found ways to connect to people like them (which would have been impossible in the past). They've found validation about their identity and made real friends. There's so many positive aspects about the society and world we live in today. But because there's so much opportunity for connection today, there's also so many more opportunities for rejection which, as the author puts it, "becomes a painful memory, no matter how many."

Occasionally I'll think to look up someone that I hadn't thought of in a while on Facebook, only to find that they, some time ago, removed me from their friends list. No matter how far removed we were from each other in real life, this always kind of stings. The action requires effort on their part; they look at my profile and evaluate our friendship, or lack thereof, and actively decide that no, they don't want me to be a part of their life anymore, no matter how socially removed Facebook is from it. I've been removed and rejected from participating in their life in this way.

I've also dealt with people of whom I thought I was pretty close and they suddenly drop all contact with me. What did I do to make her not want to be my friend anymore? I don't know. Should I have done something differently? Probably. Is she going through some shit? I don't know and I can't find out. It's frustrating and depressing and is damaging to my already fragile ego.

I don't really have any friends, anymore. There are people that I will occasionally talk to but every year it feels like I've become more and more isolated, despite the fact that there's so much more available out there. Internal factors like depression, anxiety, and ADHD play a part, for sure. When you stop participating in social activities enough for long enough, even the most loyal friends will stop putting in the effort to maintain a relationship with you when they get so little back in return. It's selfish to expect them to do so.

Life marches forward at an almost cruel pace. It doesn't care that I need a breather. That I'm starving for affection or that I'm searching for the faintest drop of connection with another human being. It cares not that the rejections are piling up on top of me making it gradually harder and harder for me to move. It continues on and I have to keep moving forward. Hopefully at some point on the way I can find someone who, if not ease my burden, can at least commiserate as we continue to march forward through it together.
The is a big difference between a template and an algorithm.
Why did you delete your blog comment system and move here, if you're not going to respond to questions?
It’s possible countries with mega populations don’t have this problem. I wonder if people in India or China have any disillusion that they are one out of a billion in their country, and are nothing special. It’s possible they value whatever the hell life gives them (whatever friends they have, whatever family, whatever job, etc).

The west is taught that we are unique. Really? Let me connect everyone to the internet and show you how untrue that is. Now what do you value?

It’s the type of existential crisis of finding out you are really not to the right of the normal distribution, and in fact, dead smack in the middle (or to the left, horrifyingly).

Someone can easily stop talking to you. You didn’t sincerely believe you were special did you?

Could be wrong though.
> If more states ban covid-passports, I wonder if the EU would rather not have tourists than allow visitations.

That's certainly a possibility if safety really is a concern. But I'd wager that the average American anti Covid fanatic (the sort: Masks are fascism! It's like what the nazis did with the jews!) is not really the kind of person travelling the world.

I don't think that others, who want to travel the world really mind getting the necessary documentation.

The whole principle that you need to prove vaccination to be let into a country is not really new. And there's the yellow vaccine passport issued by the WHO, which exists for decades.

I needed to show proof for a yellow fever vaccination when travelling to Venezuela. And that was in 1989.
> The total energy usage shouldn't be much of an issue as we'll move electricity use from refineries to charging batteries – I believe these are at least in the same ballpark.

I wouldn't be so sure. Back of the napkin estimate: for every 2M electric cars, you need 1 more nuclear power plant.

- approx. 18 kWh per 100 km for a Tesla
- let's say 15000 km per year (close to the average in France for example)
- total consumption over a year for 1M cars is roughly 2.5 TWh
- total production of a nuclear power plant varies, but is roughly 5-7 TWh per year on average

That's a lot of extra power if you want to replace all the cars. For example in France, that'd be the equivalent of 20 extra nuclear power plants, or the equivalent in nuclear + solar + wind + coal/gas/...
Anecdote warning: I've already been wearing a mouth guard when sleeping for years due to bruxism. It's perfect for that. A couple months ago though when I was ~15 pounds heavier than I am now, I started to wake up struggling to breathe a couple times per week. Now that I lost the weight, it stopped completely. Mouth guard didn't help me there (or maybe it did and that it could have been much worse). It's probably better wearing that machine though.
I don’t know whether on-street parking is as common in the US as it is in Europe, but the solution being quite widely adopted in the UK is to utilise the “leftover” current from when street lighting was converted from sodium to LED to retrofit EV chargers to the lamppost. It works really well up to about 7 kW I think. This is then supplemented with inner city rapid chargers at 22-50 kW.

Not as cheap as charging from the wall but (in London at least) other incentives like free on street parking and no congestion charge more than make up for it.
Where are you finding that an acre of solar will generate 350 Mwh of power?

My local solar power plant is nowhere near that kind of output.

The details of how this is done seems to matter quite a bit, and if I'm reading this[0] right, if the officers have the discretion about when to turn them on or off use of force might be higher compared to no body cams.

Its relevant to the subject matter of the article. Potential financial conflicts of interest should be disclosed, and that never happens in relation to the media and their interests in maintaining union power.
You can still get in with a negative test even if no passports are recognized between EU / US. Getting tested maybe annoying for sure, but it's part of the scheme going to Switzerland, and presumably to EU also.

I think everything depends how long the covid is issue to the hospitals of the destination country. If the vaccines are very potent, as it looks like from in Israel, then it might be that most of Europe & US can already travel freely without passports at the end of year.
Heat pumps drop in efficiency the colder it gets and only work down to a certain temp. If the outside coils get too cold they freeze up preventing it from functioning properly. would be interesting to know how cold the Tesla heat pump can operate down to and if it has resistive backup.

Edit: looks like the heat pump only works down to about 14F then it runs the heat pump in recirculation mode to basically turning it into a resistive heater with COP 1, its also seems to have 12v aux heat strips.
It's been bothering me too, but it's been several decades since my Algorithms class in grad school and I thought maybe the definition had changed.
This misses the point. The issue isn’t the generation, it’s the last mile grid infrastructure to the huge portion of homes/apartments where solar isn’t feasible.
> they don't all charge at the same time,

Battery swaps
All recent electric cars can manage multiple 30+ mile trips on a single charge. Bad privacy around supercharger stations due to streaming is definitely an edge case.
That sounds great. Imagine if you could move to anywhere in the EU and continue using everything the same way, just have a country selector dropdown and everything works the same way.
People without a ton of disposable income probably aren’t buying electric vehicles today (or brand new cars in general). The industry will cater to those folks in the medium term, I think; but for now I think it’s just one of the trade offs of being an “early adopter”.
Try nose masks. I have been using them and find them very comfortable. I am amazed how our noses don't feel bothered at all with the additional pressure.
The Lisbon Treaty was, in practice, a repackaging of the earlier "EU Constitution". In general, people seem fine with the EU behaving more like a single country, as long as it doesn't _represent_ itself that way. Most people, say, don't have a problem with the Working Time Directive (which is quite a country-ish thing to do; there are actual countries with less unified employment rules than the EU) but would be a lot less comfortable with cosmetic stuff (like calling the Lisbon Treaty a constitution, even though it clearly is one).
Does anyone know of a good NVMe-of storage chassis where the pricing is listed on their web site?
I initially thought they would take off, when I didn't know about the tech. Then I found out they charge batteries so they kind of have the worst of both worlds.

Whoever designs a cheap, safe, durable, light, easily mass produced hydrogen storage material will be a multi billionaire.
Supply is well matched with current demand.

The Tesla "charging station" I've personally been to was a few chargers on the edge of a supermarket parking lot (I live in rural-ish Michigan).
New York's was 90 days, then 180, then a year. They've been extending it as the data from the early clinical trial cohorts age.
That's because the infrastructure is not ready yet. I live in one of Europe's most dense areas, with street parking anf thin roads. Local gas companies started installing chargers in many places, essentially transforming two existing roadside parking spots into charging stations. Most people do only short trips and wouldn't need to charge more than 1-3 times a month, so this should generally work out as long as there are enough spots, and else its a trip to a nearby fast charger.
This makes so much sense. Now i feel bad for him that he got flagged so badly.
Given that I think cannabis, MDMA, pyslocybin and other drugs are far superior to alcohol, I don't think most people would categorize my beliefs as puritanical. If anything it's puritanical "old ways" beliefs that keeps alcohol as the primary drug despite an enormous array of extreme negatives.
Where I live it's unlikely that the next car won't be an electric. Everyone I know who bought a car the last year bought an electric. My only concern is that I need a practical car, not something like a Tesla. I need ground clearance, for example (lots of snow here). It looks like that won't be a real problem, or at least it's getting there. At worst it would be a chargeable hybrid.

Charging won't be much of a problem. Chargers everywhere, it seems (last summer's holiday was a long car trip through half the country, due to Covid), and I have 400V 3-phase at home (as most do in this town) so I can get a fast charging station.

And we have charging stations at work already.

I imagine the situation is different in the US, longer distances, for example.
Tons. This is great to slap in temperature controllers, actuators, control loop things and the like. I would probably use this in lieu of the Pi Automation Hat for things like my greenhouse controller, if I didn't already have the parts for it.

It would also be great for making into RS232 driven GPIO boards using a simple protocol.

Actually I'd love to see someone develop a daisy-chainable automation IO board using these. Auto-sense the neighbors, assign registers to I/O pins, and make a protocol based on Msgpack or a subset.
Because in Andreesens world the baddies are the guys who point out he’s investing in projects to enable fascist, not the actual fascists. The worst thing you can be in Andreesens world is Kara Swisher asking “do you feel responsible for sexist bullying on the platforms you fund” - because Marc Andreesens personal hero is Marc Andreesen.
> What I don't understand is why brands throw so much money at very young influencers.

What I don't understand is that we, as a society, allow it.
I'm guessing that you have never been on the receiving end of an explosive device.

This scares the shit out of me. Call me naive but the idea that somebody on the other side of the planet can set me as a target in a device that they just set and release is completely inhuman. If you want me dead, then do me the curtesy of at least putting your own arse on the line to achieve it.

The potential for this type of device to be cobbled together is well within the capability of pretty much any reasonably funded electronics hobbyist, and I think one of the reasons that we haven't seen it more frequently is that hitherto it's not been morally acceptable. If this type of weapon becomes mainstream in government arsenals then you can kiss that goodbye.
> NVMe to ethernet is simply making the SSD the endpoint

Confused by this comment. NVMeoF is about tunneling the NVMe command set over a network, instead of tunneling SCSI over IP or Fibre Channel, when communicating with a NAS-like device; not about plugging an ethernet cable to the SSD.
Electric cars aren't as good for destroying the planet as gas cars, but they're better than nothing I guess. We can still get the job done, it'll just take a bit longer.
How the World Ran Out of Everything
They need more brands and more models. And they need cheaper models or at least a big second hard market of old, beat up EVs.
British Colombia is wary of them on the basis of inequity, which is not unreasonable, that said, they may be doing something for international travel.

The Swiss thing looks kinda complicated, and likely hard for other countries to participate.

Easy Solution: issue a passport insert + seal.

Go to the hospital/clinic, show your passport, they give you a seal, a stamp, a number, and a signature.

The number can be typed into a computer to match with last name and first initial so border people can check.

The insert can be some kind of things that's hard to fake + the stamp would be required.

Alternatively - you take a doctor's note down to the DMV and they issue you a little temp/card/id with your name and photo.

So there's a 'central standard' but no overarching bureaucracy.
Oh God, here we go again! I confirm that by searching on lumendatabase[0] requests to remove defamation posts are found;

again these requests are very specific and in Italian, so I suspect it is from the same victim of the stalker/harasser, so I suppose that ONCE AGAIN[1] instead of removing individual defamatory posts, google has 'decided' to nuke the entire group.

For the sake of completeness, the last time I couldn't get anything out of, the whole experience with multinationals of a certain calibre nowaday is to talk to cheap and dummy bots or worse: people who are so underpaid or unprepared or uninterested in solving the problem that they don't even try to understand it.

Well, that's a big one. Apparently the stalker annoyed the wrong person.

This[2] "Court Order Complaint to Google" was compiled and sent by Mediolanum (yes that mediolanum, Berlusconi's company shell), I have downloaded the attached documents and they actually are court orders and biglawyers' stuff... I don't think it's over.

Pile drivers are special: the bang/ping of compression and release. They are hard on those who have a reason for sleeping during construction hours.
A HVDC cable from Sahara to America would loose 50% of power, but still would charge your car overnight. As solar install itself is around 50% of it's cost, it's probably cheaper to do so in a dessert than over your house.
For some groups it is 13 years. It is thought that the co-prime-ness of 17 & 13 (all primes are co-prime, as are many combinations of non-primes, so these two numbers are not especially special in that sense) helps reduce competition for resources between those with the different periods. Nature doing its clever but simple solutions thing.
Well I have never seen vending machine that had beer or other alcohol, so I'll take your word for it.

But that one small downside. It's not like you can't get beer anywhere.

I know I can order beer from our grocery stores online, and as far as I know they don't perform any age checks since I pay with cash on delivery most of the time. But I am in my 40s and look that way so I maybe they just don't bother asking.
Don't apartment blocks in the USA have parking inside the complex? i.e. you buy an apartment and a numbered parking space or two? (I don't know -- I've never lived in one, so genuinely asking.)

Then the answer to your question is: through a normal 110V power point in their parking space. Which might involve a visit from an electrician to wire it up, and (possibly) installing a submeter for the consumption -- but nothing complex beyond that.
My brother in law was considering a Tesla, so I decided to see what charging stations are near us, just outside of Chicago.

The nearest Electric Charging Station of ANY kind is 3 miles from him, in the back corner of a Chevrolet dealer's service bay. He doesn't have a garage, nor electrical service capable of dealing with charging.

As for me, I've only got 100 amp service, so I'm not sure how well I'd fare. I also don't know how long a charging cord would last outside in the Midwest. The nearest actual superchargers are 1/2 hour away. There are at least 100 gas stations in that range for me.

Infrastructure is the problem, no matter how well it might be glossed over for an outsider, this short little peek into reality has me knowing I won't be going electric in the next few years, at least.
From your first link, isn't a lot of that difference between 30 GW peak and 20 GW at night due to solar? It seems to provide about 9 GW during the day, that removes most of your estimated 70 GWh of extra overnight capacity (unless I'm reading it wrong).
I believe there is active research in micro fluidics to do exactly that.
A charging station at home is a net benefit in my book. That’s a good chunk of time saved each month.

One reason can be that they want to develop their branding as a long tail distribution of fans.

If you look online, you'll also find baby naming websites that e.g recommend your kid to be named like a Disney comic figure.

I can't pinpoint, of course, that this their motivation, but to me it'd make sense.
