> Eventually, I had to learn to rely on the standard instead of folklore; to trust measurements and not presumptions...

Indeed, testing your assumptions, because even a defined standard may result in a differing implementation of it. Especially in critical applications, testing the expectations gives some sense of a defined behavior.

This quizz is amusing as a mental exercise and a parable, but in reality all of these cases had to be fleshed out on a real platform, with real compiler and ... specified expectations of the behavior.

None of the cases in fact communicate a clear intent, except maybe #1 to figure out the padded size, still it's somewhat open-ended. Perhaps returning a specific condition (return sizeof(struct ...)==5; ) would show a clear intent. Not that it would change the right answer, just such a case may indeed be true on a specific platform, compile flags erc.
I’m not aware of any practical nuclear weapon design using U-233. Can you cite one? The tests I’m aware of appear to be inconclusive as to whether U-233 works as weapons material. They seem to have resulted in a fissle or very low yield device, have significant purification problems, and were dropped as a research pathway by all nuclear powers that worked with it.
They've definitely affected criminal law. The secret barrister's book describes it quite well.

I love Utrecht. It's a college town with the cultural and intellectual vibe that always engenders. It's a very modern town but you can turn a corner and walk half a block and suddenly it feels as though you just took a time machine to the 16th century. Best of all worlds.
On the flip side of the “easy open packaging” coin, I’ve seen scissors broken by plastic blister packages.
another way to look at it is that 2 days of free time is 2/5th of your worktime. that's almost half a job worth.

if you spend 5 years in a job, then that's 2 years worth of free time. imagine what you can do with all of that.
I like Boxcryptor too. But I've never liked Truecrypt/Veracrypt. I only use Linux, so my machines and external drives all use LUKS.

Also, I use VMs a lot, so LUKS encrypted VDI is my Truecrypt/Veracrypt equivalent. One advantage is the ability to use dynamically allocated DVIs. So VDIs can start small, and grow as you add more data.
What myth would that be?

> The 40 hour work week is tyrannical.

If you are stating this seriously, I often wonder why there isn’t a great movement toward a reduction in working days/hours in the modern workplace.

It’s kind of mind boggling to me why we have to trade most of our waking hours for the majority of the prime of our life to make a living wage. Modern society should be solving for this.

This is beautiful. It's amazing how the good side of the Internet really shines through in these pieces. Things like the 7,000-word script and professionally-narrated audio story for the kid to listen to are examples of how people sometimes go out of their way to do an amazing thing for little to no recognition, and that's what makes it even more wonderful.

I believe this is what Internet communities should aspire to be like, to cut through the toxicity and memetic warfare and just do something great together.
It's great that you have these skills, but it's unsurprising that lots of people don't bother anymore. Nobody really needs to build a shed or fix a car themselves anymore.

I say this having been raised by a loving immigrant dad who was forever tinkering in the garage. We had the worst of both worlds; we were reluctant to ever hire a professional because Dad could fix it, and Dad had an ever-growing list of things to fix, and less energy to fix them as the years piled on. He left us with two half-fixed cars, a half-finished shed, a jury-rigged pump system for rainy season, and an overgrown yard.

It's ok to have somebody else mow the lawn.

Yep plus 1000 to this. I tried doing this 4 years ago and it was a miserable experience. And rightly so to be honest. For every privacy focused nerd, there are 1000 lowlife hackers and spammers trying to use something as a bounce proxy.
I think this is a really compelling approach!

What sorts of applications have started to adopt this?

I also thought a different layer to start at would be sqlite databases since I understand that many mobile application use that.

How do applications handle conflicts? It looks like there is a version on files but when is a new version created? On close?

Do you see GDPR or any other compelling event that will cause applications to consider this sort of cloud storage?
Yes: The classic uranium gun-type weapon design works beautifully with U-233. Very low spontaneous fission, very excellent neutronics.

U-233 is unequivocally excellent weapons material. That's undebated fundamental nuclear physics. A Significant Quantity of U-233 is defined as 8 kg, better than U-235! [1] The folks down at Los Alamos aren't messing around.

When people complain about JVM, very often it turns out that they hate the first letter in it. I felt the same, for very long time I ignored Clojure because I hated "Java" part of JVM. It turns out - JVM in fact is a pretty solid piece of tech. And not once I had to deal with Java code since I started writing Clojure. Don't hate JVM because you don't like Java. Bashing on Java might be well reasoned, but hating JVM (most of the time) is completely baseless.

Actually, in Tokyo I noticed it's common for drivers to wait for their clients for hours, sleeping in the car with the air conditioner on with the engine running, hopefully this is one step closer towards solving that issue!
Having written a conforming C compiler, at one point I knew everything there was to know about C (I forget details now and then, or confusing them with C++ and D).

But knowing every engineering detail is not the same thing as knowing how to program in C effectively. It's like being the engineer who designs a Grand Prix car. It does not mean you can drive it faster around the track than anyone else. Not even close.

For example, the C preprocessor is surprisingly complicated. I had to scrap it and rewrite it completely 3 times. If you try to make use of all those oddities, my advice is don't waste your time. Over time I removed all the C preprocessor tricks from my own code and just wrote ordinary C in its place. Much better.
Can't even make the test. Which version of C? Which platform? Under DOS in the 90's, the answer to the first question would have been 3, it's not even proposed in the options.
Even better, get your ham license before you need it, and practice getting on the air with emergency nets and just to chat with fellow hams.

Any HN regular should be able to study for a few hours and pass the Technician test. This gives you access to all the VHF and UHF frequencies that are often used in emergency communications. A bit more study and you can get the General license, which lets you use more HF (potentially longer range) frequencies.

Here is a good place to start:

https://hamstudy.org/

Many hams start with a cheap Baofeng handheld. These sell in the $25-60 range. Here's one I have and recommend - it's at the high end of that range but has several improvements over the cheaper ones including a better antenna:

Ham radio has been popping up on HN a lot lately. Besides emergency communications, there are a lot of interesting things you can do once you get your license. Feel free to holler with any questions!

Just a minute after this quiz, if someone were to provide the answers and descriptions of what had to be written and asked me to write it in Lisp, I'd probably get 2/7 or 3/7, covering only the simplest of examples.
Fair enough. I've suffered from so many bugs in commercial software that I made some design decisions at the beginning of the project, in an effort to avoid more egregious faults.

Primarily, PhotoStructure doesn't touch, move, or delete any file that it hasn't generated. It only copies into your library (if you pick that option). See https://support.photostructure.com/why-doesnt-photostructure...
I've somehow made the transition from lifelong software developer to making physical objects with wood, perhaps for a living in the near future. I bought a CNC laser cutting/engraving machine in May and am now earning a decent income making things from wood and selling them online. Turns out, designing websites and marketing graphics translates pretty directly to designing home decor using much the same software. As it's now a "business" instead of a "hobby", that's allowed me to stockpile all kinds of interesting types of wood for experimentation and future projects, though I only use a few kinds for actual products so far.

There's also a noticeable difference in waves. Some quakes hit you with a lateral motion (which, I presume magnifies any possible liquefaction). Some hit with a rolling motion (which really wreaks havoc on masonry). And some hit you with both (those are the ones where you hope the building doesn't collapse on you).
Bladder cancer is sometimes treated by immunotherapy with an attenuated form of tuberculosis (BCG), so I wonder how revolutionary this is. Maybe the side effects aren't as bad? Maybe it's safer?
This. All day long.

On the current code base I work on I swear every single one of my pull requests contains large amounts of variable and method renaming to make it easier for the next person because if it takes me half a day to compute an understanding of what "var result = apiTotal - total" is actually doing then it isn't named nearly clearly enough.
You said:

> That seems unlikely, as that requires like 11km/s which is more than the sum of the two velocities[...]

Isn't the first problem here that you're assuming a spherical cow in a vacuum physics problem? Two satellites colliding aren't two indivisible pebbles colliding.

They're going to pulverize on impact, and some of the now-expanding debris cloud might even contain combustibles the satellites were carrying.

The debris also won't only collide once, there'll be a series of rapidly occurring re-collisions. Some of those might impart extra velocity on some of the expanding debris.
Based on Elon's standard playbook, I'm guessing he's going to try to bring down unit economics with much larger scale in phased array manufacturing than we've seen in the past. If he didn't think he could do this, I don't think they'd be launching Starlink.

That said, I know almost nothing about phased arrays, so I don't know if it's expensive due to some fundamental reason, or if it's partly because it's been a niche/low volume device before now.

Nobody wants an i3 because it’s a stupid looking car with no market edge over I.e. a Tesla

And nobody can afford an i8

So they may as well threw their market lead for nothing. They failed to make a practical vehicle, like the electric 3-series sedan that probably everyone wished they made.
It's not just Japanese. I'm French and I had no idea khaki was some kind of beige in English. In French it's the same colour as in Japanese. As far as I know, it's also the case in Dutch at least (Dutch, or Flanders, maybe it depends on the place rather than the language).
> Nearly as disturbing as the number of people who tell me they use free VPNs.

This is absolutely not an apples to apples comparison, but why is it outrageous to believe there couldn't be a free VPN that focuses on privacy when there are search engines like Duckduckgo and browsers like Firefox that are completely free and are pro-privacy? I haven't done the research, so consider it a rhetorical question.
But doesn't that carbon footprint assume that the energy to manufacture and transport the panels comes from fossil fuels? Then it seems we would eventually reach a point where a sufficient fraction of the energy to produce and transport would itself come from solar, leading to a reduction and eventual elimination of that carbon footprint.
Safe? Against what?

- Preventing websites from seeing your true IP? (you'll want to disable webrtc as well[1].) Mostly yes.

- preventing your ISP from spying on your traffic? (allowing Amazon to spy on your traffic in exchange...) Yes.

- Avoiding risk of legal threats if you engage in copyright infringement? Mostly no. They can subpoena Amazon instead of your ISP, and your lightsail/EC2 ip isn't shared.

Routing through a vpn, whether it's a commercial one or through AWS, linode, digitalocean, etc. will get you blocked on far more sites, because it's more difficult to identify individual clients, and there's more fraud and bot activity on any kind of vps or vpn netblock than there is on typical residential netblocks.

There's really not much Lisp/Scheme left in R these days.

Function arguments/environments are still pairlists: a type of cons cell.

You can manipulate the parameters to a function as symbols before you evaluate them. This is useful — many very good R libraries all make heavy use of it — and certainly very interesting. Lispers probably know it as quote/antiquote.

I suppose we could also point that, much like most Lisps, R gives you plenty of object systems to choose from...

And that's about it for R-as-a-Lisp.

It's also a really bad language for working with tree-structured data, something Lisps normally excel at.

Yes. :) After the initial shock, they barricaded themselves into the storage room behind the garage, because there was a pull out couch and a phone in there. But we couldn't call them because another phone in the house had been shaken off the hook. So we drove down there as quickly as we could and when we got there everything inside was rubble, the chimney was just a pile of bricks, etc. (although the house itself was still standing).

We got shovels and started digging, calling out their names. Finally got the back and found them sleeping in the pull out sofa! We packed some of their stuff and took them back to our house since we had minimal damage (despite being thrown from bed) and then went back later to survey the damage.

At that point people in the larger multi-family buildings had all evacuated and set up tents in the median strip on the main street (Ventura Blvd). Many of those buildings were condemned.

If Netflix ever goes to a model where I have to watch ads, I'm out. Now if they implement a tiered model where you can pay to not see ads (ala Hulu) then fine - depending on the details of the price. For me though, I'm not interested in paying and seeing ads. No double dipping...
I feel very strongly the amount of free time is, to a great extent, a social standard rather than some economical constrain. I believe 35 hours work week is no less productive (or even more). I wonder how many believe the same and whether we can push it as a community.

Really excited about this project. Nothing else solves the centralized Oracle problem quite like ChainLink has. I think this will be the project that gives crypto a lot more mainstream adoption. Most exciting thing to come out of crypto since Dai (in my opinion, more exciting).
Thank you for your reply and all your work.

I probably should have phrased my comment better. My point was that it’s perfectly possible to use ggplot without explicit knowledge of tidy principles or tibbles. This is great! And for example, I’m reading through your ggplot book and it doesn’t make reference to it.[1] In my work, we use data.tables (we believe we need the raw performance) with ggplot for visualization and are not using the rest of tidyverse and it works fine.

Why couldn't they? C had already existed for a couple of decades when 32-bit machines started getting popular. `int`, as the default integer type, usually is the size of the machine word for best performance. It would make no sense to have slow, emulated 32-bit ´int`s on a 16-bit system, never mind 8-bit ones.
