Comparing oneself with other people on a single dimension is a bad idea because likely the most extraordinary thing about that other person is what stands out. Said otherwise, it’s the reason you chose them as a comparison point.

Same with people posting fancy pictures on instagram.

You don’t see that they have a chronic but unseen illness, and that their children hate them, for example.

Specifically though when I see people who have accumulated much more wealth than I have, often they’ve been doing it much longer. It makes more sense when I remind myself that. And yeah I could have started saving/investing earlier, but if the best time to plant a tree was 30 years ago, the 2nd best time is today.
Isn't the notion that you have to follow through a prime example of the sunk cost fallacy?
In economics terms, my preferences are not complete. You can look it up if you bother to understand why "if A is bad, I don't necessarily buy the alternative B".
It makes sense to build a cheap and dirty system to start. Especially if you want to build it then inject loads of cash when it takes off. But it is still a cheap and dirty system.

Too many people do build like this initially but are not willing to pay to fix the mess when it starts to get hard to add new features.
Json diffing.

I haven't found any implementations I'd consider good. The problem as I see it is that there are tree based algorithms like https://webspace.science.uu.nl/~swier004/publications/2019-i...
and array based algorithms like, well, text diffing, but nothing good that does both. The tree based approach struggles because there's no obvious way to choose the "good" tree encoding of an array.

I've currently settled on flattening into an array, containing things like String(...) or ArrayStart, and using an array based diffing algorithm on those, but it seems like one could do better.
I’m just telling you what their client actually does based on a previous analysis I conducted, not the claims of their documentation.

The private key is auto-generated by the Backblaze Client installer and gets sent to their server at install time. This is done before the user has any choice to set a passphrase. Setting a passphrase later does not generate a new keypair, it just sends that passphrase to their server so the server can re-encrypt the private key using the new passphrase.

Because the key is uploaded at install time and doesn’t ever change, they already have the private key in unencrypted form. When a user tries to protect it, now they also have the user’s passphrase. There is no technological way by which “PEK” shields your data from Backblaze, even at rest, as implemented.

This limit is called the Hill Sphere: https://en.wikipedia.org/wiki/Hill_sphere

For the Sun it's a bit more than 1 light year, but in practice almost all orbits will be quite a bit under this: less than 0.8 ly.
Question. Does it have to be a planet out there?

Could it be a small black hole?

Or is it just a matter of us not spending the time/effort to find it. I know time on instruments like Hubble is very, very tight and scheduled out years in Advance. But they have been talking about Planet X since like the 80s at least, and probably earlier.

Even Pluto was detectable relatively early and it’s on a crazy orbital plane and elliptical orbit.

> If 50% of students in a classroom get infected after 2 days in school while wearing masks then, IMHO, masks can't be all that effective in the first place.

I believe the primary assertion has always been that making protects others more than it protects oneself. So I wouldn't consider this a contradiction of that. That said, it's entirely possible that the 50% of students who didn't get infected were wearing superior masks. Or, perhaps 80% of the students would have been infected if no one had worn masks.

In short, you can't really draw a meaningful "see masks don't work" conclusion from this.

Both are factors in good centering, but mostly the change in diameter. In turns, there is a natural tendency for the train to shift towards the outside of the curve due to inertia. The wheel diameters become asymmetric which helps to re-center the train. It's usually not sufficient on its own, which is why superelevation is used as well - the outside rail is somewhat higher than the inside rail which shifts relative gravity to pull the train back towards the inside as well. The relationship between these two effects is a bit complex (depends on weights and speeds of trains) so it's usually all a bit approximate.

The conical section of the wheels is mostly intended to prevent hunting on straight track, and the shape can't be made too aggressive without increasing the wear on wheels on rails. So on curves the superelevation is added to provide the extra force required.

Because conical wheels do increase wear and can contribute to oscillation in their own way, there have been experiments with cylindrical wheels especially on higher-speed trains---BART is a well known example. It ultimately didn't work very well and so they have been re-trueing the wheels to a non-cylindrical profile, although still not quite a traditional conical one. Basically in higher-speed operation the re-centering effect is too significant and causes one wheel to "chatter," which over time creates a significant vibration in the rail. Trouble is cylindrical wheels tend to cause the same thing to happen on the other side. It was a very hard problem before computer modeling became available.

It could be that you don't have a 'library component' defined in the project. Its dune file will look like e.g.:

When you have that, 'dune utop lib' will open the REPL and load the library.

"Easier than inventing Rust" is very much not the same as "pretty easy", though...

>All these companies care about is money.

That is not the problem, at least as far as I am concern. They have no problem with making money. We dont live in a communistic world.

I have a problem with them pointing their fingers and using media to start a cultural war against others, claims to have moral high ground with their PR spin all while sucking up as much money as possible against their own so called values.

This is exactly the same as Google in early 00s. The we dont do evil and self claim righteousness. Or Hypocrite.

So dont cry foul when all the other companies are working together against you.

I think it's more significant that wild fruits, grains, etc are quite different than what we have cultivated. I.e. wild strawberries are extremely small and many of the fruits still eaten by primates and other animals are really quite bland.

I find it a paradox that everyone seems to know our food is unhealthy for ducks..
Adding another step (not a problem, just maybe a solution), a quick estimate says that if I place a few kHz signal at the sample, it will induce enough current at the tip to be detected by the preamp when the distance reaches the micrometers. That's the same range you want to stop the approximation, so it may be a nice proximity signal.

I've got to try this on my next attempt.
My question is -are these extentions part of the features in newer CPUs that are being exploited like Spectre etc or is it completely unrelated. I ask because if it is, then it may be a feature (or set of features) that's going to be going away.

I originally wrote 5-10 but didn’t want to seem too ominous. But yeah, I’d bet on some serious issues in the latter end of the 2020s.
ls actually uses readdir() from glibc, and glibc's readdir() calls getdents()/getdents64() (I checked the source)

It's not solving a problem Linux used to have - I used "-f" or "find" to avoid this issue first time sometimes in the mid 90's.

But a lot of people aren't aware, and it's perhaps a poor default and/or it'd be nice if ls output a warning with a hint if a stat of the directory indicates it's likely to be a big one.

The buffer size probably does make a difference (and current glibc scales the buffer based on st_blksize reported from stat, up to 1MB at most), but on large directories "-f" and/or avoiding anything triggering a stat() will be a far bigger deal than upping the buffer size.

It would be nice if there was an easy way of adjusting the glibc buffer sizes though (currently it takes modifying constants in the source and recompiling glibc to increase it.
It is not true, you see it because people like to brag. But they prefer to hide their problems, sometimes very deep. The society discourages talking about these things unless you are close friends. Whereas positive aspects are amplified.

I give you an example. I have a couple of friends with two kids. They have an amazing FB/Instagram feed. You immediately see a wonderful model family living in a beautiful house, traveling together, enjoying every moment together, all smiling. It seems like they are always having fun in all possible places (it made my other friend who can't have kids a bit depressed).

One day I decided to visit their house and was a bit shocked. The kids were basically terrorizing the family. The father was half-alive but trying to smile all the time, sometimes unsuccessfully. The whole house was very cold because they spent too much on it and couldn't afford heating it adequately. But the most depressing was a bad smell from nearby chimneys of their neighbors. Apparently they couldn't do anything about. For me it was a living hell, I couldn't live in such a place for one day.

Google uses a similar scheme of compression in their Safe Browsing v4 protocol: https://developers.google.com/safe-browsing/v4/compression It calculates deltas (adjacent difference) between a sorted set of numbers and then use Golomb encoding on that.

> Students don't learn a thing from testing. Most teachers don't either (it's supposed to help them tweak instruction, but that rarely happens).

Testing isn't supposed to teach, it's supposed to motivate kids to learn stuff they aren't interested in. "Put in the time and effort or else". On one hand it's barbaric, on another I don't think making every kid interested in everything is realistic. If you want every child to learn math you have to force at least some of them.

> Education is all about capitalism.

Education was possibly even more soul-killing and bureaucratic in communist countries.

As for oppression angle - sure, everything society does is built on power hierarchy. It's not specific to capitalism. Got any alternatives?

If it was an "all hands" meeting, then I assume we're talking dozens, maybe hundreds of employees attending, with the vast majority of them not contributing/speaking. How do they know you attended? Couldn't you just skip it and come in later? We're all grown-ups and should have a good handle on what is really necessary for getting our job done, and have the good judgment to skip the things that are not necessary. I pretty much skip meetings where I have nothing to contribute and the world has so far not come to an end.
Also 'dune utop' which loads your library directly in the REPL, which is quite nice for iterative development.

two to four weeks submerged while idling? hardly seems like an improvement over diesel boats. also, what is the limiting factor? are they literally out of fuel, since they cant just snorkel to recharge batteries? or do they carry some kind of liquid oxygen maker? if they can make LOX, why dont we compare how long before diesel refueling is required?

I think they (the dashboard team) were worried that if other teams started building their own dashboard, that'd indicate that the dashboard team wasn't that useful. Which could mean they would get fewer promotions or raises, or might even get fired if bad days came. -- So they wanted ownership of all dashboards, whilst actually building them, was less important. (Is my interpretation.)

The new dashboard team manager, who appeared in the end, seemed to be a bit more "get something done" minded though
The browser isn't optimized for text files though, but for documents and applications. I've noticed some flickering while scrolling longer pages before, and from that I expect that there's some caching of the rendered content of the page.

The text file also gets transformed into a html document with DOM (inspect one in Firefox to see), which likely has its own caching tricks for performance.
Sure, but this is a coprocessor on an expansion card, similar to a GPU. I've worked on a few systolic algorithms and this kind of chip has massive potential in that space. TPUs have been a big letdown in that regard, as they don't even have the comparison operation needed for the matrix-based shortest-path algorithm.
Don't worry, most of those people will be broke again in two years. Easy come, easy go.

Yes I concur: CTEs is closer to the spirit of relational algebra: every step/expression should yield a table/relation.

As data munging is about combining/correlating/sorting/grouping data, why not have a sound (bag) algebra to do that? Such algebra would give us equational reasoning, proofs, etc.

And consequently: students would be learning an algebra which is easier to learn IMO.

I was not going to comment but then you clarified what you were looking for and I can say “we’ve used Sandisk Extreme Pro USB 3.0 in 32GB - 128GB in every ESXi server for probably over 5 years without any failures.”

I’ve heard they released a bad SKU that they then retracted - I think it may have been the first 3.1 variant, but it’s no longer for sale. The only problem is they are bulky, but I believe there is good reason for that.

This is a viable solution, and an old one. My only comment would be that if I was you I'd make the filename the whole value (so your 4097'th item would be /0/0/1/4096.item). From experience it makes it (marginally) easier to change the directory structure if you decide you need it in the future if you don't have to rename the files. It's not a big deal, but it's been convenient.
It will only work for coastal vessels until they get the sat-to-sat thing working. I know Elon talked about bouncing the signal off base stations on barges in the middle of the ocean, but not sure if that would be reliable enough.
That's a problem. Their basic claim is that they have, running, a fab for 28nm to 65nm flexible ICs capable of making a billion units a year. They claim 1-day turnaround. They claim to have a 6502 and one of the smaller ARM CPUs working.

What they seem to actually make is RFID tags, which are low-end flexible electronic devices. They promote RFID hard. ("Is RFID the solution to protect and promote wine?") The actual product they sell is described here.[1] "At the core of these new cost-effective smart solutions are Avery Dennison’s NFC inlays, which include NFC ICs from the ConnectIC® range of products manufactured by PragmatIC, a UK-based world leader in ultra-low-cost electronics. As these flexible ICs (“FlexICs”) are thinner than a human hair and robust, they are suitable for small diameter objects and provide the ideal solution for adding a unique identity to cost-sensitive products, for example small syringes, or vials."

So what they seem to be trying to do is take a technology useful for RFID tags and use it for more complex devices. As a demo, they've made some CPUs.

> Could it be a small black hole?

It could, the relevant part of the whole thing is the object's mass (and therefore its gravitational influence) and its orbit.

Lex Fridman did a podcast interview a few months ago with Konstantin Batygin [0] about the topic of Planet Nine and he poses this exact question of whether or not it could be a black hole [1].

More specifically, he asks if it could be a primordial black hole which would make it a double discovery since primordial black holes are still only theoretical.
