Regenerative braking does not replace traditional brakes. In particular it is only really efficient at high speeds and doesn't do much in cities. EVs have no tailpipe emissions, but particulate emissions from the tailpipe of modern ICEs is very low anyway. But EVs do produce significantly more emissions from the tyres and brakes compared with ICE vehicles because they are heavier.

It's the same in Europe too (or at least the parts of Europe that I'm familiar with); you can buy shelf-stable milk, but I don't know anyone that does.
Look at the evidence. Lidl (and ALDI) are exapnding all over the world. Meanwhile Walmart decided to pull out of Germany because the competition was to tough.

ALDI and Lidl are world class at selling a limited selection of medium quality goods to a massive audience at extremely cheap prices.

It's unclear how any of the technologies you mentioned would improve that core competence. It's also unclear that any of them could threaten that core business. Maybe we will all get our groceries delivered by drones in twenty years, but it's not obvious that that is true. And it's not obvious that being a follower on this, rather than a leader is inefficient for LIDL.

I could turn it around and say that in the US there seems to be a penchant for high-tech solutions "just because" rather than thinking about whether they make sense. One example: In Germany we don't have any voting machines, never was even seriously discussed. Every ballot needs to be counted by hand. Yet final counts are available on the night (with further verification done later). Some analysis based on experiences in the Netherlands also suggests that it's cheaper to do it that way.
He did it for a number of years so I imagine he got some sales.
> but they all trade extremely close to parity with one another. Which means that they are all considered relatively safe by the people actually holding them.

trading rather than holding. The people doing the trades are the ones determining the pricing. The people holding are reducing the supply of the asset in the market, but they're not actively participating in pricing of trades.

That seems overly stereotyped. North American companies that fail to innovate do so at their own peril. They languish, and eventually become irrelevant. Kodak, Sears, RIM (Blackberry) come to mind. So do the non-Tesla US car companies. General Motors, Ford Motor Company, and Fiat Chrysler Automobiles.

Accumulation of wealth can never be analysed in its own vacuum, because it does not exist in a vacuum.

Present day accumulation of wealth creates a huge power imbalance, billionaires are citizens, just as I am, why should they have more power, as a citizen, than I do?

If you defend that billionaires should exist then, in my opinion, it's required to design a way to protect the rest of society from this class of people amassing more and more power.

The problem isn't money, it is our power structures. Right now, being a billionaire is almost inherently bad, every billionaire is a policy failure.

Re: your last point, the determinant is the matrix function, which is fully anti-symmetric under permutation of rows and columns i.e. swapping a pair of rows or a pair of cols pulls out a minus sign. The definition of the determinant is related to the alternating representation of the symmetric group.

The permanant [1] is the matrix function which is fully symmetric, so permuting any rows or cols leaves it invariant. It emerges from the identity representation.

Finally, partially symmetric matrix functions are known as immanants [2], defined using the other irreps of the symmetric group.

I worked in the Real Estate Dept at Lidl for a (very) short time, awful company. Never have I seen people being treated so badly, especially in stores.

Their IT was an absolute joke back then, we had to use a 20-year-old ERP and most of the work was done on paper. Thinking that these guys could take on AWS sounds ludicrous to me. However, they are cost-killers and hyper-aggressive when it comes to selling, so this might even work...

> Should he be forced to give up his ownership in the company he built?

How do you even picture that claim? Is it Bezos literally building every warehouse with his own two hands? Is it him being at a thousand places at once dealing with paperwork, marketing and packaging all by himself? For every billionaire out there there are thousands of workers that were denied their share of the success. I would say the only way someone could be a honest "self made" billionaire is by mugging an other billionaire in a dark alley.
Better OS is highly disputable. Emacs has point where can win against against VS Code, as also points where is lose. It all depends on your demand and usage.

Customizing can be a curse. Seeking it purely for the sake of customizing is an harmful poison. VS Code has some areas for improvement, but it's good enough as it is now. It doesn't need to be as programmable as emacs.

That's a very poor salary for your job, if you don't mind me saying. Are you in Italy? What's the cost of living like?

Salaries in Europe are generally quite low for devs compared to the US. I think it's best in the UK.

Starting salary will average ~£25k, rising to ~£35k as you get more senior, then maybe £~45-55k one you're 5-10 years in.

This is excluding London and contract-based work, of course.
So, taking the standard diffraction limit calculation, I get a resolution of 15km using an orbital height of 250km and an aperture of 2.4m (as the KH-11 uses).

That resolution is inversely proportional to the aperture. So you could get it down by taking larger apertures. The best way to do that would be a phased antenna array, but that is computationally very expensive. It would be very cool though.

Yahoo! Pipes a strong argument for building your own tool/buying a paid product, in that if one relies too heavily on a service and it went away, then that [business] process went away as well. The demise of Pipes! caused us a bit of anxiety and made us hustle to find other solutions in a compressed time frame.

The rather quick demise of Yahoo! Groups was also disruptive. Heck, even Hacker News could have worked as a Yahoo! Group. Fortunately, it is not. When Groups went away, so did a lot of discussion groups and even when those groups moved, they lost many members. Groups.io is a nice alternative, but there too much of their platform is free.

There is always a danger when you build critical things on someone else's land, particularly if they allow you on their property for free. Even if they charge you but are not profitable, there is a risk of waking up to read that the service is closing.

We use Zapier in our small business, but work to build out tools for those Zaps! that become mission critical.

This sounds a lot like the days in web dev before Ruby on Rails came along.

When they (and django) took the web dev world by storm they were prescriptive and told developers how to do something, not just giving them a bunch of tools where you had to build your own app lifecycle, usually massively over-engineered. A whole load of mental overhead disappeared.

Just before Rails, etc. everyone was going on about Factories and the Gang of Four and people were building crazy startup patterns on their webapps using Singletons.
Because all higher-level components must be created out of primitive html tags with a sprinkling of attributes, and it's nice to have a convenient way to create those. This is the same reason why modern languages include some kind of object-literal syntax rather than relying purely on constructor functions. Even C has a comprehensive syntax for initializing objects now. E4X was just that for HTML and XML.
You don't really have much of a choice about keeping food services open in some fashion. No virus is as lethal as starvation.

>that means that LOCKDOWN_COVID19_MORTALITY_REDUCTION - LOCKDOWN_EXTERNALITIES >= 20 million wellbeing-years.

Absolutely wrong. And you are missing:

- lockdown reduction in suffering, due both to the acute phase of the disease and after effects

- No-lockdown-externalities, including damage to the economy if the disease is allowed to spread through the entire population

And perhaps most importantly:

- the risk that a huge reservoir of infected people will lead to repeat waves caused by mutations, and even worse that cross-species infection occurs (we already know cats and dogs can be infected - pigs and poultry could be next); then we risk flu-like antigenic shifts.

Put all this into the equation and I think the only thing we should be contemplating is how to eradicate the virus as soon as possible.
Ok, without wanting to sound like a crazy guy, this book has really had a large impact on me : https://www.amazon.fr/Finding-Your-Own-North-Star-ebook/dp/B...

It's basically a method that helps you find what exactly get you on, what you get energy from, and how to reach it.
Of course it requires a lot of introspection but the book helps you there.

It sounds cheesy I know, but that book had enough impact that it really changed the way I worked, and make sense of why I was so frustrated at times. Couple months after reading the book, the company I work with offered me a tailored job because I was finally able to clearly communicate what it is that was driving me.

There's definitely more of an opportunity in EU cloud services than you might think.

I work for a pretty big EU university (~50000 users) and there is very little AWS/Azure/Google we can actually legally use. And this isn't a case of "bureaucracy gone mad" either, there are some real concerns with the big cloud providers that the rest of the world doesnt seem to have the time or the energy to tackle.

Another thing is that AWS/Azure/Google are getting _super_ complex. The idea of a back to basics cloud provider that fully complies with GDPR might actually be a compelling offering.

That said- whether this kind of tech can come from a budget supermarket chain in Germany is another thing all together. Despite the hype, not much exportable tech actually comes out of Berlin, and its not clear that they have the breadth and depth of expertise in "open source at scale" to make this actually happen. But on the other hand- who knows? Will be interesting to see.
If you're wondering what the definition of a legal name name even is in the US, it's explained here (at least as the SSA sees it): https://secure.ssa.gov/apps10/poms.nsf/lnx/0110212001

It's also interesting how they handle different spellings of the "same" name, e.g. apparently "Elsa" and "Alice" have only a "minor difference": https://secure.ssa.gov/apps10/poms.nsf/lnx/0200302460

Variations on the foam cutout or outlines of tools have been in workshops for at least a century, as good tools are expensive. Its not done everywhere as it’s a pain to setup, and you need discipline to keep following it.

Preventing surgical instruments is easier the more expensive the tool is. Anything over $5 can easily get a RFID tag and you can simply scan the patent then the work area to get accountability. The hard part is with gauze and other cheap items that can’t easily be tagged, and will be going inside the body, so they have very high biocompatibility requirements (eg: inks in spectrum transparent to blood might be too toxic to use).

Parent says Eastern European country, well, I had the bad luck to be born in Hungary (am Canadian now), and I fully understand what happened. It's a generation divide. I am 45 and I am one of the oldest for whom it doesn't matter and looks downright outdated but even to many in my age cohort and especially older it's exceptionally offensive, irrespectful to use the familiar form of "you". https://en.wikipedia.org/wiki/Hungarian_noun_phrase#Forms_fo... With a huge emphasis on irrespectful -- it's downright disdainful to call someone so without asking for permission to address them so. There is a tradition -- or rather was -- where they used to toast on the occassion of switching from formal address to informal. It's that big of a deal: there was a ritual, simple as it was, on switching the form of address. In the 1920-30s the gendarmerie used to address everyone informally and it was really offensive and a form of asserting dominance -- it was always the superior, the elder who offered the inferior, the younger to switch from formal to informal thus the gendarmerie not even offering just using it declared they are vastly superior to everyone. And the phrase still exists for such offensive behaviour. It really is -- or rather was -- a big deal.

I am saying, it was, because starting the late 90s with the spread of Internet and pseudo-anonimity all this just became outdated -- you had no idea whom you are talking to so observing the old rules were impossible. And those who have grown up with this simply didn't bother learning the rules. For me, when I was 18, it was a Big Deal that at our high school graduation party our class leader teacher allowed everyone to switch from formal to informal. It was basically the only time in my life when something like that happened, then I started using the 'Net shortly after (all this was in '93) and this stuff was just washed away.
I think this crisis will make young people seek careers in safe fields, shielded from major booms and busts, pandemics, and with decent benefits.

But who knows, people also have quite a short memory, so it might be forgotten 5 years down the road.

So, with that, I think schools / majors that are aimed at "essential services" will see a rise in applicants.
Also, for online retailers to put their eggs in Amazon's basket means they put their destiny in the hands of a competitor. Going for example with Azure is safer from this perspective.

> Blame is a useful tool, it feels like you're trying to avoid it for unstated reasons when it seems entirely useful in this context.

I've demonstrated that everything except blame is useful when doing analyses of engineering failures or disaster analysis. I have professional experience in this both in the computer science world and in the traditional engineering world.

Identifying root causes like "lack of testing prevented deployment of limited resources optimally which exacerbated these effects: X, Y, ..." is a useful and actionable way to identify and address problems. And then people can look at these blameless analyses and make their tough decision, and then go beyond and demonstrate accountability for their choice. This can be repeated as many times as necessary all around the world, within nations or across nations in a collaborative response (such as the joint vaccine development initiatives).

Adding "blame" just exacerbates emotions (political or personal or what have you), clouds judgement, and usually results in a worse outcome by whatever measure of the disaster (usually number of deaths). That's my "unstated reason": blaming is an active choice that leads to more deaths as history has shown repeatedly, whether by famine due to supply chain issues plus political rejection of food aid, or a "not invented here syndrome" of rejecting medical supplies, or societal instability resulting in mass protest and political revolution (and more death and starvation), for example.

I don't blame Trump for Covid. Just like I don't blame China for Covid. There are a set of things China could have done differently, just like Trump could have done things differently. "Blame" is really saying "Trump should have never had to do any preparation differently because China should have done things differently," which is the definition of living in an alternate reality. Life says "tough shit" and doesn't treat him like a special snowflake. Plus it does not inspire confidence in the kind of leadership principles the President is following: just how many other things is he relying on others like China to do so that he doesn't have to make any preparations?

If I were inclined to distrust China, instead of blaming them I would be crapping my pants with how emphatic the President repeatedly assures the American people that he relied on them to manage such a disaster for him (and us). That is what he is saying when he tries to blame them.

I think China did as well as they could -- it was a bad outcome because it escaped -- but shutting down their entire society for a few months to bring their new cases down to 0 was effective for them. Sucks it escaped their borders but it's no longer their problem at that point. And it is scary that the whole free world is looking at the authoritarian regieme and going "gee they got down to 0 new cases" and then look at the Leader of Free World USA's high daily new case load and cringing. And then looking in horror at Want-To-Be European Leader Of Free World Germany reopening and watching their daily case rate rise.
Shrinkage in the form of shop-lifting also has an effect.

Ask HN: I've been promoted to Architect. What do I need to learn/do to excel?
My company had some lateral movement which, somewhat surprisingly, resulted in me being promoted to "Lead Architect". It's just a fancy title because we don't have any other designated software architects. There was, in any case, technical responsibility that needed to be redistributed, so that's what happened, and titles shifted accordingly.

In the past, I had used my training budget for software architecture certifications, which was met positively by my team lead and management.

While I _wanted_ to take on that role _eventually_, I was surprised to have it happen so early. What are the things I need to learn ASAP? What things do I need to do? What should I study/read?
