This is kinda expected, in many parts of the World mobility is going towards smaller vehicles, with limited range and load capacity, to be used in crowded cities (or small rural villages, for example here in Italy).

In Rome for example the Smart EV is already quite popular and thanks to the favourable weather in recent times a lot of electric scooter rental companies have emerged (see https://www.ecooltra.com/)

Also electric kick scooters are gaining popularity.

One of the main drive to adoption is the fact that restricted traffic zones for ICE vehicles are increasingly larger, especially in city centres, but EVs can circulate freely and are often exempted from on-street parking fees.

Tesla are not the solution to the mobility issues these vehicles already solve.
Smashing Pumpkins were the best in the early nineties. Gish and especially Siamese Dream are great albums. I saw them at some festivals around then. Amazing.

I still get chills when I hear the guitar intro on some of the tracks from those albums.

I saw them during some of their later tours and though they were great gigs, I think I had drifted away from their music and in fact the whole scene. I was getting into electronic music in the late 90s.

I'm not American, so can't speak for them.

Pretty much all kids in my relatively small town have scooters. The girls have Vespas or some Vespa lookalikes, whereas the guys do wheelies on theirs. Some seem to like a Mad-Max style where they get an old scooter, and strip it almost naked, some have nifty ones that look very sports-bike like. Bigger kids have 125cc motorbikes. Some look like dirt-bikes, some look like sports-bikes. You could say that Ami would resist the elements better. But it doesn't seem like the kids mind rain much, or that Ami was particularly well suited for winter months.

If I was 15, you'd see me dead in one of them Amis. I'd take a 'naked' scooter I can do wheelies on any day.

This seems to be a general problem with these small EVs, people always believe there's someone else that will surely buy them. As long as it's not them.

This is the line I was responding to:

but if you can't afford to have a roof over your head I'd argue the smartphone is irrelevant.

A phone and tablet and internet access were essential to my ability to cope and eventually get back into housing. They aren't irrelevant.

If you want to argue we need to do a much better job of making housing something people can afford, I totally agree. If you want to argue that homeless people just are supposed to entirely cease to exist and not care about anything people in homes care about or something....no. That absolutely doesn't work as an argument.

The internet is a really massively helpful thing for people who are homeless.

That's not how quotes work :-)

The article is saying Amtrak, a half baked VIA, is the closest thing they, in Texas, have to CN. That's not saying CN is close to Amtrak.

If my buddy has a Humvee and I say, "Unfortunately, the closest thing I have is a Schwinn", I'm not saying their Humvee is a bicycle.
> Of course, it might get worse when they get hit by a faster driving traditional car

as a counter example, in Rome a lot of people drive scooters to escape traffic jams, these vehicles offer improved safety over a two wheeler.
I've found glass-bottled water easy to find in Belgium, I buy cases of Ginstberg (they have both still and carbonated water) in glass bottles in a supermarket here in West Flanders.

I know at least a couple places where you can buy it (Huis Maria in Harelbeke, Vanuxeem in Ploegsteert, so both Flanders and Wallonia) so I would assume those to be widespread enough throughout the country.

To me coming from France it was Belgium that was the easier place to find glass-bottled water :)

Solar won't help in a winter storm when the sun is not shining and all your panels are covered with snow. Wind power also tends to go down when there's too much wind.

Everyone loves to pick on air conditioning, but the recent disaster has shown that heating is also a huge problem. As your statistics show, heating can consume more energy than air conditioning depending on the region. AC only needs to lower the indoor temperature by 10-20F, whereas heating requirements can exceed 50F. This makes it a much harder problem to reliably produce the amount of energy needed to keep people from freezing.

Climate change can bring not only hotter summers but also colder winters and more energetic storms. We desperately need methods to generate clean energy even during extreme weather. Especially during extreme weather.
I hope they try. At this point I just want FB, Google, Murdoch and AuGov to collide in an abysmal trainwreck of policy and petulance.

None of this has the citizens of Australia in mind at all, so I hope all the companies involved fuck themselves over by accident.
Did you even read the article? He does have a heat pump. He just uses mining to pre-heat the air, reducing the energy consumption of the heat-pump when the weather is cold.

When it gets really cold, heat pumps can lose some of their efficiency, so in that case this might not be much worse than just relying on the heat-pump itself.

It's still not a net-gain environmentally speaking, I guess, but since he uses GPUs he already had lying around I'd say it's not very bad at all.
There are cons as well. Manufacturers are mostly moving away from buttons, which is arguably a safety issue. It's harder to find hydraulic steering so we're left with the muted electronic racks you find today. They have all sorts of technology you find useful, but I actually spent a significant chunk of time figuring out how to remove the modem in my car. Oh, and they're typically much heavier, the bane of any performance vehicle (and bad for the environment, fuel economy, and safety for pedestrians).
Adding a property to an object that does not belong to the object is pretty much the worst workaround to comments, in addition to it being much harder to read due to lack of comment specific syntax highlighting.

I don’t think a bit transition is in any way comparable to the “event transmission” to a potentially extremely large number of interconnected other neurons.

An actor-based system would be a better model, and I’m not sure if we have something like that in hardware. I do agree that sometime in the future it will be possible to overcome the biological limit, as cells are most definitely not at an optimum (probably not even at a local one), like duplicated pathways and the like, but it is no way trivial.

John von Neumann had a great paper on the topic, at least his thoughts about it. It is a really great read, even though both technological and biological advances may make it outdated, I think he did see a few things clearly into the future.
TLDR: HP = torque x RPM / 5252

Such big engines runs at low RPM, below 1000 (I have not looked at this particular model). It's common for boats to run at 500.

In comparison, my 2.2 liters 2007 diesel mercedes runs at around 2400 RPM at cruising speed of 65mph, which is its max torque. Max HP (150) is achieved at 3500 RPM. It's by no mean a sporty car but it's low RPM torque allows to pull the horse van easily.

The freight carrier boats can feature impressive diesel engines, of thousands of liters, producing millions of Nm of torque, hundred of thousands of HP, at ~100RPM.

Shorting a company that’s «looking pretty suspect» right before it appreciates by 2200% is pertty much the definition of being very, very wrong.

Burry probably didn’t do that badly, but any successful Tesla short in the last 2 years has happened at times when the company did not look particularly dangerous. Excluding the macro crash at the start of the pandemic.
Can't you just drink tap water, or if it really tastes that bad use a water filter. The idea of buying a new bottle every time you want a drink of water seems insane to me!
> A side effect of the clumsy Streams API in dotnet is that the antipattern of reading a Stream into memory (e.g. with a MemoryStream) is prevalent - we’re guilty of it ourselves, in places.

This seems a little unfair to compare bad C# practises to good Go practises. Of course, if you unnecessarily load data into byte arrays, GC is going to be a problem. But you don't have to do that. Even if you're using some 3rd party API that doesn't support streams, you might be able to use pooled byte arrays, or even pass a stackalloc'd Span for small data.

The author does a lot of hand-waving about 3rd party libraries, but since they don't actually name them, it's impossible to comment on that

This has very seldom been a problem for me personally, but it might depend on the 3rd party libraries that you use - the author does a lot of hand-waving about 3rd party libraries, but since they don't actually name them, it's impossible to comment on that.

> There’s also the fact that even idle dotnet processes can consume hundreds of MB of memory

This is contrived; it's only true if those idle processes were previously doing a lot of work that made a lot of allocations.
It's not even good for machines to communicate with, considering:

- There is no minimum/maximum number/integer value (or sizes) defined in the RFC [1] - you have no guarantee that a number you emit will be readable by all RFC-compliant parsers, so the only safe option is to emit all numbers as strings. There is also no behaviour mandated for parsers that encounter numbers/integers outside of their supported size range, so you can't rely on any fail-safe behaviour.

- There is no standardized behaviour for repeated dictionary keys (which are allowed but 'discouraged' per spec), and different implementations will treat them in different ways. This is especially painful when trying to build JSON middleware that does a parse/check/modify/emit of arbitrary data.

- Implementations in some languages (eg. Python) are non-RFC compliant by default (`python.dumps` will emit NaN/Inf/-Inf, even though the RFC forbids that), and generally all implementations are similar-but-different-enough to trip you up [2].

All three of these have bitten me in the past when trying to interface with something that spoke JSON, and as such I refuse to design new systems that use JSON as any source of truth.

I've found that the cheaper processed meats (chicken, burgers etc.) have the most convincing plant-based alternatives, usually from soy protein. Any seafood or dishes where the meat is the main flavour such as steak there's just no alternative that comes anywhere close; same goes for vegan alternatives to cheese.
What I found most helpful when going vegetarian was realising that it's not an all-or-nothing type situation, and if I can go completely vegetarian except for eating tuna or steak a couple times a month then that's better than not trying at all, even though that's not an argument I've really seen repeated all that much on the internet.
That’s like saying there is no animal faster than a horse for transportation... until you realize you don’t need animals at all to get you to your goal. Yes you can’t replace the experience of a steak, but you can replace the satisfying meal with something non-meat (I’m not vegetarian).

I agree imitation meat usually tastes like crap but I’ve had great vegan fried chicken in Japan where I didn’t even know it was not meat until after the meal. That and just getting used to all the non-meat stuff you can eat (ramen, MSG, bean curd, legumes, kimchi). In American cuisine i think of vegan food as imitation meat and stramed veggies...

I think what most people associate with meat is actually the flavors that go into the meat-centric dish most cuisine is based on.
The worst thing the US government would do is regulate tainted Bitcoin by keeping a database of all Bitcoin that were connected to a specific crime. If your Bitcoins randomly become worthless because the US government prevents trading of tainted Bitcoin it could easily cause a long term price decline as more and more crimes are being uncovered and more Bitcoin become tainted. A global agreement with the EU and China could strengthen the potency of this database.

As interesting as these data are, I’m not sure if there’s necessarily anything wrong with the value of reddit’s MAU. As the post lays out, it has a liminal feel to it, but that sorta loses its punch if you put all thrusters into redesigning without any clear goal.

As it stands, I find reddit’s award system nice in principle, but in practice it feels so obnoxious that, ironically, I paid for a third-party client that smooths over the UI weirdnesses and hides this layer. But it ultimately remains a layer on top of things that can be hidden. Change that up, and it becomes something the user can’t ignore, and you risk damaging community at the expense of profit.
It's hardly surprising that a short news piece summarising the conclusions of an entire field of study does not engage itself with challenging the frameworks used.

Nominal wage stickiness, recessions etc has been the subject of an enormous amount of study (and wage stickiness is sufficient, but not actually necessary to cause recessions). And the exception to the rule that increasing the money supply is dealt with by the very next sentence from the one you've singled out as a gotcha. Liquidity traps were already baked into the theory.

Imagine if somebody dismissed the field of computer science as a distraction from database problems based on a blogger listing CAP theorem as one of its essential conclusions

> but woodlands in Europe aren't 'nature' in any primitive sense.

Europe is varied, not sure where you live but the forests in Northern/North-Central Europe that I'm familiar with absolutely do support wildlife. I think it shouldn't be controversial that returning agricultural land to nature, whatever "nature" means in different areas, is good for environment.

Anyway, this is wildly beside the point, which is that pasture feeding cattle can't satisfy the current demand for meat, not even close. Converting soy fields to grazing fields would be an ecological disaster without a serious decrease in worldwide meat consumption, as the yields would be far lower.
I ran into this the other day, and it took me a moment to realise that I could just use `matches!`:

// want to do this
if not let Some("pattern") = val {
doSomething();
}

// can instead do
if !matches!(val, Some("pattern")) {
doSomething();
}

I wonder if we could make it even better and make smart heaters that instead of wasting calculations actually do something useful, something like folding proteins or some other computing load that doesn't require huge network load and can be easily distributed (something like SETI@home but actually useful).

In densely populated cities we could bury huge datacenters underground and use that energy for heating directly, and use excess to produce electricity.

I only have a superficial understanding of the legislation, but my impression is the opposite - it requires Google/Facebook to enter into good faith negotiations with news organisations that can choose to negotiate individually or collectively.

There's a Q&A from the ACCC (Australian Competition and Consumer Commission) that drafted the code:

https://www.accc.gov.au/system/files/DPB%20-%20Draft%20news%...

> How would the code benefit smaller, regional and rural news media businesses?

>The bargaining power imbalance between news media businesses and the digital platforms is particularly acute for smaller, regional and rural news media businesses. The draft code would allow news media businesses to bargain with a digital platforms either individually or (more likely) as part of a collective. Bargaining as part of a collective would allow smaller news media businesses to negotiate from a stronger position than negotiating individually. Collective bargaining is likely to also reduce costs for individual news media businesses, and allow groups to pool resources and expertise during the negotiation process.

Unfortunately I suspect this may go the way of many freelance sites, and get absolutely flooded with low quality indian developers.
Where the wage is lower $0.75 may seem a lot more attractive and there are a lot of fresh out of university indian devs.

If you've ever tried bidding on remote dev jobs online, you'll practically always get undercut by an indian dev at a price you can't even come close to matching, and unfortunately I suspect that given how often they appear in comments online asking people to do their entire project, I suspect they may often be bidding for jobs they don't know how to do.

I’m not anti-Microsoft. I own stock. I want it to do well for my family.

But I’ve seen firsthand the ignorance and arrogance of a .Net-based development team. It’s like having taken all the old bad VB programmers and given them the equivalent of Legoland to live in. Their company is paying Microsoft for expensive SQL databases, Azure this-and-that. They restarted IIS instances and Windows servers regularly. Now they restart their Docker container instances. They have no fucking clue why. By the way, they run the development team.

Hats off to those in Microsoft that open-sourced things. That’s better than it was. I accept Nuget and other ideas they copied from the wider development community.

But there’s a long way to go before I see anything “Sharp” and assume it could be legit.

I think there have been some great engineers and developers working on Microsoft initiatives.

Brains do have plenty of “backup systems”.

There are similarly many many more “primitive” systems in place, like you will continue to take breaths even at “shutdown”.
