> It's an interesting article from 2004; might not be reading it right but seems like this one from 2020 is less optimistic about hydroxyl radicals (OH) breaking down PFOA in the atmosphere. https://pubmed.ncbi.nlm.nih.gov/31978654/

That's an interesting paper. If so, multiply the atmospheric time by 2-4.

> Your same link notes that the majority of PFOA is not broken down in the atmosphere and points to "wet and dry deposition" mostly, which sounds like it's being dropped down to Earth remaining as PFOA.

Yes. That doesn't affect the "half life" here.

In the end, not much PFOA ends up in the atmosphere in the first place, and most precipitates out to less convenient places where it lives longer. Of the stuff resident in the atmosphere, it does break down on human timescales, at least...
France's newest operating reactor, Civaux 2, entered commercial operation in 2002:

France started building its first unit of the next-generation EPR at Flamanville in 2007:

https://www.world-nuclear.org/reactor/default.aspx/FLAMANVIL...

There was a ~5 year gap where France stopped work on adding reactors. France would probably be building more EPRs now if the planned 5-year construction of Flamanville 3 hadn't stretched out to 15 years:

This is a pretty solid game. Two thoughts:

- It is so hard to maintain control that it feels unfair rather than challenging on tricky levels.

- The game should reward the player to give them a sense of progress - this will prevent many of them from quitting after struggling for a few minutes. A leaderboard could work.
Just as the third party doctrine is used to subvert the fifth amendment, now the surveillance capitalism is good to subvert the first amendment. At least in the third-world countries, and countries ruled by tin-pot dictators, ordinary people are aware of what to say, what to do, and stay within those boundaries. The land of freedom, which the US is said to be, is a giant illusion.

FWIW: This wasn't an issue on Windows Zoom. The Apollo-era Unix permissions systems that MacOS uses was the issue. More modern OS, like Windows 10 and 11, don't have this vulnerability.
This is completely wrong. Literally almost the opposite is true.

There are lots and lots of countries who use nuclear civilian energy and don't have nuclear weapons.

While at the same time there are lots of countries who have nuclear weapons but no civilian nuclear power.

In fact, it would be more accurate to say that countries who have civilian nuclear power are less likely to have nuclear weapons.

https://en.wikipedia.org/wiki/Treaty_on_the_Non-Proliferatio...

The NPT allows countries to have civilian nuclear power but not nuclear weapons, and many do. My country, Switzerland being an example. Japan is a large country where this applies as well.

The connection between civilian nuclear power and nuclear weapons is almost non existent. Countries that want nuclear weapons, just get them directly, they don't develop civilian nuclear power first.

So please stop spreading this harmful misinformation.
Once again, their insecurity is our freedom. One does wonder whether those who were asked to implement this "security" were not happy about doing so, and just decided to make the equivalent of a speed bump instead of a wall.

I remember "carputers" were a somewhat common aftermarket mod in the early 2000s, mostly running a stripped-down 98 or XP on an SSD or memory card. The obvious difference being that you had full control of it from the start. Here's an example of someone doing so:

What I miss more is the “rtfm.mit.edu” FTP site, which was a repository for all the FAQ’s of all the Usenet newsgroups. I don’t even know if it was mirrored anywhere.

Sorry for answering with a question… but it’s an obvious one: how would Meta benefit from banning Apple devices?

They would certainly lose a lot of money in the process with no clear win. Other than, perhaps, an authoritarian “Zuck said so” posturing that might make a few disgruntled individuals feel temporarily satisfied.
>There should be type hints.

"Hey, this variable is probably of this type. Now go on, run the code and launch a debugger the same way you would if there was no hint just to make sure it's correct. Oh, and don't forget to check all the possible code paths that lead to this to make sure you've exhausted all possibilities."

Don't get me wrong, type hints are cool but they're just a toy compared to proper static typing.
Related question, how does typescript’s gradual typing system work? Are there any resources on how they implemented and architected it?
Oil? None.

Natural Gas? A bit, for corn-based ethanol (the Nitrogen fertilizers used to make modern corn fields requires a surprisingly large amount of energy, of which is primarily given through Natural Gas IIRC). Various calculations I've seen however, suggests that Ethanol uses less greenhouse gasses than say Electric vehicles (since most of our power grid is still coal / natural gas based). Aside from that one guy who keeps making anti-ethanol research papers for the last 15 years.

The bulk of energy going into corn is the sun, all natural solar energy. A bit of it is hacked together with Nitrogen fertilizers that must be accounted for, but still better than other methodologies. The other major greenhouse gas issue is the greenhouse gas costs of converting forested land into farmland, and this seems to be the biggest area of debate.

------------

Bonus points: Switchgrass based ethanol uses no fertilizers, meaning its 100% green. Since Switchgrass grows naturally in the US Fields (unlike Corn, which is a domesticated crop), Switchgrass is arguably better for the environment (or at least, more "natural"). The lack of fertilizers needed for it to grow is proof to how its a plant designed for our geography.

So Switchgrass solves the fertilizer and land-conversion issues.
Wide knowledge is valuable for creativity and innovation. Deep knowledge is valuable for discovering subtle yet critical insights.
I think the key word in your question is "primarily." And because of that I would say not at all. The early Internet was people having the ability to connect and communicate with others all over the world. Being able to meet, or learn, or buy from people even in the next state was completely game changing. Before it would have required physical catalogs, or getting someones phone number, etc. But the Internet made it happen at an unbelievable speed which is why it took over.

That was it's "job" per se. Did people use this new ability to try to scam others, sure, just like they did with bogus ads for hovercrafts in the back of magazines in prior years. But the technology itself was about this instant communication.

So people wanted to move all offline stuff to online. That is why first boom was just things you can do offline, but now online. Buy pet supplies...online. But groceries...online. Etc, while the winners of that era didn't just recreate offline businesses online, but improved them based on the paradigm shift it enabled.

Blockchain feels like a technology looking for a "job." I understand there are some countries where maybe the job is being able to move money, although I am not convinced that it is is net positive in those cases. The biggest thing I think I have realized is that I have never been in a situation, where I think to myself, "If I could just use the blockchain to do this, it would be incredible."

And if after all of these years, that thought hasn't hit you even once, then I think that says something about whether it is actually improving anything.
I've recently had the following idea that might make making new linear algebra libraries like this one easier. There might be some overlap with the ideas in the article, but generalised.

Assume you've got a routine for unitarily diagonalising a self-adjoint matrix with entries in the complex numbers. Call the resulting decomposition the spectral decomposition.

Now imagine keeping that same routine, but changing the complex numbers to other *-algebras. That means redefining what the operations {plus,times,minus,div,conjugate} do, while keeping the algorithm the same.

The observation is that for one choice of *-algebra, the spectral decomposition changes to the SVD, and an SVD-algorithm is obtained directly. For another *-algebra, the spectral decomposition changes to the Takagi decomposition, and a Takagi-algorithm is obtained directly.

The above uses operator overloading to turn one matrix decomposition into another.

This seems highly unlikely. How would Comcast be aware you were using such a device? No idea where you're located but the simplest answer is usually that cable modem service sucks.
If you essentially stop any technology progress for 40 years in one technology, other technologies might catuch up.

But there is a MASSIVE amount of potential for nuclear to be cheaper and better.

People in 2000~ were more then happy to predict massive improvement in cost for renewables if money was invested but absolutely denied that the same could happen with nuclear.

Had the same amount been invested in nuclear, prices there could also have changed.
>At the end of the criminals will just use a flatbed tow truck to steal the vehicle if it is worth enough.

Working-class teenagers in Milwaukee do not use flatbed tow trucks to steal cars.

>The "immobilizers" you're referring to are the bane of my existence from my perspective. Instead of getting cheap $5 copies of my keys made, I have to pay something like $120 to Ford to get copies made.

Ask anyone in Milwaukee whose car hasn't been stolen whether they regret having an immobilizer.
It ain't "marketing drivel". If it were, it would be an utter failure.

It is a profound insight.

It might be a wrong profound insight, but "drivel" it ain't.
Yes! I want to know whether stainless steel is considered just as safe.

While formal HOWTOs might not get much attention, it's pretty clear Linux tutorials of all types are both being made and consumed in a variety of media. People often bring up how much value they get out of the articles DigitalOcean puts together, for instance. Those aren't HOWTOs necessarily, but does it matter?

There's also the fact that people just consume that kind of content differently nowadays. While it's hard for me to understand, people younger than myself seem to get a lot out of guided video tutorials over text.
Bad SEO I suppose. When I search for something, I often get a page by some "expert" in which the information is wrong, commands don't work and so on. I wish I could figure out how to eliminate them from my search results. The worst part is that it is usually impossible to contact the author and point out the errors. Like they would care.

Pricing decisions can be subtle. I like to try and calculate the value I delivered to the customer. Here are a couple of questions you may find helpful.

What are you replacing? What else could they pay for to achieve an equivalent speed up?

What are your enabling? How much time are you freeing up that can be used for other purposes?

What is the impact on time to market / release inter-arrival time?

What is the shadow backlog of tests that are not being run but now could be?

What is the impact on quality: for example time to fix (MTTR) or production problems prevented because of increased testing?

Pretty good, according to my own suggestions and predictions on crypto and NFTs months ago [0] [1].

I have already said that 90% of NFTs will fail and not all of them will survive many times before [2], and only a certain few crypto projects will survive, even past regulations.

The 'people' you are referring to were expecting all 20,000+ crypto or NFT projects to survive this crash which is just delusional as expecting all internet startups created during the dotcom boom to survive after the collapse in 2000. As you can see what I said months before in [0], [1] and [2] tells you that I am not part of the 'people' you speak of.

As always, I expect only a few crypto projects to survive this crash and regulatory clarity.

Its not a conspiracy. Its for certain that there was a real anti nuclear movement but its also true that fossil industry and Russia spent money to fund these efforts.

So it happened but how effective it was is questionable.
I agree. It's a question of how much finding his sister means to him. We don't know his story, and maybe he'd be willing to spend some time in jail and lose his career if it meant the chance to find her.
Great idea that I will incorporate into my pizza-making process.

Here are two methods that I used to get the crust to brown:
a) Pre-topping: Prep just the crust by putting the pan into the oven for 5-minutes as the temp rises from 400 to 500-degrees. Top the crust with sauce, cheese, and toppings post the prep stage.

b) Post-baking: Once the pan is out of the oven, I put the hot pan on the stove for a few minutes if the crust needs some more cooking.

For what it’s worth, I use Kenji’s recipe for pan pizza [1]. I prefer his method of measuring ingredients using grams vs. other units of measure (teaspoons, cups) that I tend to get wrong.

Not overdoing it (to start with) is by far preferable tbh. My experience, for instance, is that inflamed achilles takes very long time (years) to go back to normal. To get it inflamed was fairly easy: resuming jogging a bit too swiftly after a winter break.
Your interests change over time, which can dramatically impact what you learn. It thought from 20-30 I'd be focused on tech forever, but now I'm 40 I gravitate towards the nuance of conversation. I suspect further changes and by the time I'm 70 I won't shut up about grandfather clocks from the 18th century.

So it goes.
Sure, I concur that teens don't use flatbed tow trucks.

But if as a society, the default has become that your car will be stolen then the society has collapsed. It's more like a bunch of competing warlords, with the most prominent one being the local government.
France and Germany have been expanding local tram & Stadtbahn networks, even opening new ones since the ~1990s. Tram-Trains have also become popular in Germany, due to offering more stops in the middle.

Not sure if you mean trams or branch lines by local railways, but at least Germany has also been keen on reactivating old branch lines, often to resounding success and exceeding expectations (and few failures, although there are many hurdles that reactivation projects much pass to avoid that fate). S-Bahn networks with many infill stops are also popular.

Many S-Bahn stops also rely on walking for the last mile, which works well. There are also of-course people that come by bus or bike, but both seem like a smaller portion to me. There are efforts to try to get more bike&ride traffic to expand the station reach, but it's doesn't seem to me like it has increased a huge amount. There are also always efforts to expand park&ride, but the share of passengers using it is tiny [1]. The portion of people using E-Scooters and taking them into the train has noticeably increased, but not (yet) enough to be a significant portion (I'd guess 1-2% at most). In places where E-Scooter rentals are available, the trams, subways, busses, walking and personal bikes are usually cheaper (30ct/min) and guaranteed to be available. I'd guess few people use rentals for their daily routine, but more for fun and rare trips.

A few german transport associations have tried implementing on-demand ridepooling, but I haven't heard of any large success stories yet. It's more of a complement for off-peak service due to the waiting times (if it takes 20 min for the vehicle to get to you, that's 20 minutes of waiting and you can't rely on a timetable), hassle (having to use an app and ordering it) and price.

[1]: Park&Ride is very limited anyways. You can't retrofit a lot of parking to existing stations, because they're in the middle of (sometimes small) towns and would discourage denser development. If you want enough ridership to sustain an additional stop, there'd have to be a huge amount of parking (necessitating expensive parking garages) and enough demand to take the train for part of the trip and not a car for the whole trip. There usually isn't (with some exceptions, like greenfield HSR stations that the french like).

This is literally what mypy does.

There's no difference between a mypy-enabled codebase and a java codebase in terms of static typing (other than that mypy actually supports a generally richer type system).

Like yes if you aren't validating the type hints you aren't getting the value, but if you are, you don't need to run the code! I get most of my python errors at compile time, and you can too. I promise.

> refined and shipped across the planet by hostile nations such as Russia and Saudi Arabia or through local fracking.

And where do you think the Nickle that your Li-ion batteries use comes from? (Hint Russia). The core manufacturing capabilities of Li-ion batteries are almost entirely foreign. Nickle from Russia, Cobalt from Congo, LFP from China.

If you're trying to make a US-centered argument, the thing about local fracking is that it is US-centered and therefore subject to US laws and regulations.

> There are cobalt-free batteries, and you don't need to use child labor (even if this is the case now, which I doubt). Lithium is super abundant.

> Because lithium’s concentration in ore at Thacker Pass runs as low as two-tenths of one percent, producing one ton of the stuff for use by society entails strip mining and processing as much as 500 tons of earth. Over a single year, producing 60,000 tons of lithium at the site could mean digging up as much as 20 to 30 million tons of earth, more than the annual amount of earth dug up to produce all coal output of all but seven or eight U.S. states.

Are you sure that the oil slurpped up through a straw is really more environmentaly damaging than hundreds-of-tons of mining activity per bit of Lithium?
Personally I believe Linux has matured to a pretty decent usability level for the average user. Ubuntu, Opensuse, Linux Mint and some of the like have taken a lot of the hard work out of managing and installing a linux OS. It used to be that you would slave hours of getting your specific hardware to work with a particular flavor of Linux. Now you have drivers that are plentiful and up to date, bugs that get fixed fast, and large communities at near enterprise levels maintaining the updates. Frankly a pretty good time to be a Linux user.
These geological repositories are such political bullshit theater. Its fucking sad.

Its just crazy that we live in this world.

The US collected money from nuclear plants for 50 years for disposal, and had plenty of money to develop waste burning reactors. And yet that money is totally unused. While politicians dead-lock on this idiotic Yucca Mountain project.

Its beyond sad the state we are in.
If I recall correctly, the common lisp community doesn't like nor recommend the book at all.

I tried to keep going through it but eventually gave up and picked the much better practical common lisp.

Hanging, drawing, and quartering wasn’t very common in the long period it was a criminal punishment (in part because the kind of things that it was a punishment for often ended up with the accused being killed before facing judicial punishment – and were the kind of things that would have been true of even without the added pressure of the particular punishment that awaited them.)

Though the mid-16th through the 17th Centuries were an…interesting…period in that regard.
