> As far as I can tell, it seems like a large (20-50) percentage of people who have a large windfall... end up losing it all because they don't take the time to learn how to handle it.

I agree with all your advice, but I think that^'s impossible to tell. The vast majority of people successfully and sensibly handling such things are (partly as a result or even 'input' of it) not talking about it.
The Linotype machine has become a kind of obsession for me. It is dizzying to think about the impact this machine had on the entire media landscape of the last 130 years. Not only did it allow for regular newspapers that were longer than a few pages, it also dramatically decreased the cost of both newspapers, books and magazines. In a way, an entire century stands on the shoulders of this machine, invented by a single man (Ottmar Mergenthaler) who was obsessed with it to an unhealthy point:

> One of Mergenthaler’s greatest setbacks was that he could not stop inventing. He constantly wanted to improve upon the machine. This made investors angry because they wanted to ship the machines and make money right away, but Mergenthaler kept coming up with new ideas—delaying the shipping process. A publisher of the New York Tribune, named Whitelaw Reid, tried to make money fast off of Mergenthaler’s invention. He began to criticize the Linotype design, in hopes that the stock price would decline so that he could buy more and take complete control of the devices. This put a lot of pressure on Mergenthaler, who was already a perfectionist and worked late into the night. Eventually, Mergenthaler’s health began to suffer and he died of Tuberculosis by age 44. His premature death meant that he never lived to see the success of his Linotype invention [0]

But it is also the technical aspects of the machine that are so fascinating: the bucket sort mechanism for the matrices used a 7-bit code for each character, encoded in the matrix teeth [1]. The machine supported text justification in a completely mechanical way. There are just so many small engineering gems in this machine, and at the end it prints out a cast letter mold. All that in a mechanical machine that fits into the corner of an office.

Mergenthaler was the Gutenberg of the 19th century. Unfortunately, almost nobody knows his name.

Because cars sit out in the sun in hot countries all day (unavoidably), the automotive supply chain have developed quite rigorous standards for pretty much everything in a car.

Typically every electronic component must be rated from -40 to +105 C. I'd imagine there's similar requirements for all the interior parts of a car too. Cars have a lot of glass, so get very hot in direct sunlight and quickly reach ambient on cold nights.

The reason cars take so long to "catch up" to consumer electronics (eg it's only in the last year or two that large LCD displays have started appearing in cars, or that LED headlights have become commonplace) is that the car design cycle is very long - typically about 7 years. Tesla decided to do things differently, which meant they could iterate much quicker. It also meant they used components not qualified for automotive use. Mostly they got away with it, but there have been some issues (for example their large displays started failing in hot countries).

One of my pet-peeves is how common it is for applications these days to assume you always have a reliable Internet connection. The shift to webapps makes the whole system really fragile. All it takes for an app to become unusable for everyone is a failure in just a couple nodes in the system.

I don't use GitHub for work, but it's always amusing to see the cries of people who do, when it does down from time to time. The ability of many companies around the world to continue operating depends on just one company continuously making the right calls.

In the future, when Ubisoft's servers go down, I won't be able to play Assassin's Creed games anymore, even though the servers don't really provide any value to me as a player.

On Spotify I keep downloading the same songs over and over again. Poisoning the environment more than if I got a CD. These days I try to buy songs to download once and then play in my favourite offline music player.

And of course SSH, the "secure shell", application which doesn't really optimize for shells. Responsiveness of typing things in the shell prompt relies on the quality of the Internet connection and the CPU load on the server machine - a process during which the server doesn't really have anything interesting to say.

I'm working on the side on creating a company and those opinions lead me to choose the harder path of desktop applications which don't need Internet connection for anything that doesn't require it by definition. They're more resilient and comfortable to use. I'll probably fail, but I really can't make any other choice at the moment, I need to at least try and see for myself.
You started with providing a source, then go on to make an unsubstantiated claim about Dutch supercharger use?

Ask HN: Will Ruby Get a Comeback?
I know that many of you will say Ruby is doing fine, etc... let me say that regarding jobs and adoption is not that great, especially compared to Python and a few others, without even looking at usage stats.

However, I see some attractive features in Ruby 3, do you think that's enough to get a comeback?

My main concern is jobs availability, as an employer I find it harder and harder to find good RoR developers and they become super expensive. As a startup you're start to think if you made a big mistake choosing Ruby , even if it's easier to build something, being so hard to find affordable developers offsets every advantage you had.
I'm 40 now, since the pandemics started studying game development (BA), and talking with my colleagues via discord, I'm quite sure I'm the oldest one. On the bright side, I'm the one with the best notes, delivering always weeks before the deadline, despite the fact that I have a full time job and family. I think what the life taught me at best are time management and context switching. Love to learn and be productive. I'm looking forward to still be a student in the age of 90.
It depends. In America yes. Elsewhere. Get one.

> Less than 100% reliability is essential for the sustainability of an off-the-grid solar system, because above a certain threshold the fossil fuel energy used for producing and replacing the batteries is higher than the fossil fuel energy saved by the solar panels.

I wonder if whoever wrote this has actually done the calculations. These days it's not really difficult to provide fairly reliable solar power by overgenerating while still beating fossil fuels - perhaps not beating them as much as with zero overgeneration, but beating them anyway. So I'd take the quoted text with a considerably large grain of salt.

And who is right? This kind of illustrate my point: there is no universal natural intrinsic value, it can differ a lot from a person to another. Bitcoin or Van Gogh pieces have value for those who chose to see value in them, no matter the rationality of the decision.
That is apparently not a new clause.
Considering the number of depressed people who have jobs, this seems a very questionable view.
Gas stations don't make money on the gas (with some exceptions for stations with fairly captive customer bases or in prime locations). Gas is just a break even to get you in the door. Some % of gas customers get converted to convenience store customers and that's where all the money is made.

Hence GP says 'diversify'. If you weren't an employee, or were one with no related stock in the company, would you buy so much, invest ~everything, in that (or any) one company? No? Well, don't treat holding differently to buying. It's the same, modulo fees & tax.

Automating SQL user generation and password rotation with CockroachDB
On a computer that you control completely, in Linux you can use taskset to launch programs on whichever cores you want and to migrate already running programs to whichever cores you like and there is no obstacle that prevents you to use this in some scripts to automatically implement any policies you desire.

I frequently use taskset, because otherwise Linux migrates continuously the process between cores, which can degrade the performance of the programs that do some computations with a long duration, unlike the programs that are mostly waiting for events to happen.

This new feature has a different purpose, it is intended for multiuser servers, to enable the secure partitioning of the runnable threads into groups that can be scheduled on different cores, so that they will not be able to interfere with each other, even when they would have intended that.
In The Netherlands there are (or were) Christian political parties shutting down their websites on Sunday automatically.
Oh boy, I love taking my big ass F-150 Lariat down to the drive-through ATM, through a Starbucks to grab some coffee for the hour long trip just to get some lunch in Tacoma because my mother in law is driving down to Portland to visit her sister and she figured she'd make a stop there because I live close by, I might even pick up my meds at the pharmacy drive-through on the way back and while I'm there I might as well stroll into the Target right across the 2 mile long parking lot to grab some last minute groceries for dinner!

I did exactly this, as a Dutch person living in the US, not realising how ridiculous this is compared to my home country.
This is a little off topic but I don't want to read a lot of text-heavy blogs that all look the same. Give me a little variety and some nice pictures to look at. By the way this looks nice and I'm going to check it out, too bad my Tumblr has 2500 poasts and no readers.
I would say learning and closing gaps is always part of development and must be payed. Let's say you are the most competent C++ developer in the world and have the whole STD memerized (no real human is this guy I think), but part of the current project is using any other library or framework out there, then you need to dive into that documentation. And epecially as freelancer you need to learn how the companies code base every time you switch the customer or project.

Another thing is if you want to qualify for certain freelance jobs. Let's say Qt is a thing you want to do professionally. Then it is very likely that you have to build up some knowledge and portfolio to get such a job. Then the freelancer pays for the time obviously.

I'm not sure either, and I posted it! Didn't expect it to take off.
The ideal model isn't like a gas station. It's not even a 1:1 replacement of refueling model.

Some gas station usage disappears entirely due to at-home charging and destination charging (i.e. opportunistically wherever the car is parked). You simply don't visit a special place to charge.

Remaining usages are for longer-range road trips, which are already served adequately by bigger service stations along highways. The rest is for users who don't have at-home charger and need a 45-minute weekly charge, but for this the ideal model is not a charger with a gas-station like shop, but a mall that happens to have chargers.

> The solar powered website goes off-line when the weather is bad – but how often does that happen? For a period of about one year (351 days, from 12 December 2018 to 28 November 2019), we achieved an uptime of 95.26%. This means that we were off-line due to bad weather for 399 hours.

> If we ignore the last two months, our uptime was 98.2%, with a downtime of only 152 hours. Uptime plummeted to 80% during the last two months, when a software upgrade increased the energy use of the server. This knocked the website off-line for at least a few hours every night.

And while they found inefficiencies in their energy conversion system,

> One kilowatt-hour of solar generated electricity can thus serve almost 50,000 unique visitors, and one watt-hour of electricity can serve roughly 50 unique visitors.

Keep in mind that unlike in Europe in the US processed food is often cheaper than fresh vegetables, fruits and meats. I always thought the US would be "cheap" in terms of consumer prices compared to western europe but it was significantly more expensive to buy fresh produce in US supermarkets than in Germany or Austria.

On the other hand stuff like coca cola is cheaper.
Directly, no. Indirectly one cannot ignore the influence Germany has in the EU, so his word carries some weight, especially if you are a multi-national company operating in the EU.

That being said, Andi Scheuer is quite an incompetent idiot.
Diets are a mixture of culture, availability, personal taste, cost, and social status. Culture is by far the biggest and most dominating factor when talking about diets.

If you want to be a champion of the environment and ignore culture, there is likely food that exist where you live that people don't want to eat. Invasive and overpopulated species. In order for something to be invasive or overpopulated it is likely not something that people eat in your culture.

Where I live, cyprinidae fish exist in massive overpopulation to varying degree in most fresh water lakes. They grow large in numbers from as a result from farms creating water pollution, and since our culture do not have cyprinidae fish as part of any diet, the economical incentives to fish them is only from bio gas and animal feed. That is simply not enough, and so the problem has only continue to worsen. My culture loves fish and have fish as a central figure at many occasions, but not cyprinidae so we hunt other species to extinction.

An other culture crash is seaweed, an excellent protein that doesn't use land or create pollution. Just like with plant meat there are plant fish alternatives that is constructed using seaweed. They are sadly not very popular. We could also just be eating the seaweed as it is, but people don't know how to cook it or how it fit in their recopies and lives.

Being innovative with food culture is not so much about production as it is about changing people minds. Artificial meat tries to solve this by keeping the culture as is.

Ironically it being "the future" is at least part of the reason why it happened. In the UK, all the land records are digitized nowadays, so the scammer didn't need to steal the physical deed to the property to pull off the scam. All they me had to dk was present their fraudulent identification to the office holding those digitized records and it was over without the owner even having to know.

WebPKI doesn't really solve these problems.

CA Audits are mostly about ensuring they're following the rules. However, the rules cannot stop an ISP or hosting provider just issuing themselves a cert and a fully audit compliant CA is not expected to stop this.

Cert transparency is mostly unused. For it to work people have to proactively search the logs to find certs they didn't issue, but in reality nobody does this outside of maybe big tech firms. Moreover, in the ISP/colo interception case, the CA wouldn't be revoked because they wouldn't have done anything wrong.

Re: pinning. You can't pin if your IP isn't stable. However you can if you're a server. Then you don't need the fragile link of DNS in the loop at all. For instance, mobile apps can just have a cached public key (of course you can do that today, but we're talking about a system that is more deeply integrated with the internet).
