The robot knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation.
NAT was originally delivered as a security mechanism.
I really like the word conviction here for this concept and this use is new to me; has this been used before? A casual search for me doesn't term up anything.
If you confiscated my car tomorrow, I literally couldn't get to work or buy groceries. That isn't an optimization, it's a hard reality.

Once you've built timely safe replacement infrastructure that can carry me from my home to my place of employment as fast or faster than my current commute, and take me to any of the shops I frequent, and do that for all of my neighbors, and do all of the above in a way that costs less than car ownership, we can talk.
I've noticed that surfing & bodyboarding are (maybe surprisingly) VERY cognitively challenging: watching the waves, moving your body through the water to intersect correctly, timing the launching of your board to coincide with a coming one and then making many micro-movements to stay on it, etc.

I wonder if this is an argument for prioritizing exercises like that, with a big mentally taxing component.
> a very small percentage of social media users will switch

This is a good point. All of the existing social media users are entrenched in the big 3 of Facebook, Instagram and Twitter, and that is why TikTok does not exist
A mobile receiving station? Uh? That sounds really bad, right?
I would envision a "spectacular failure" at boiling eggs to mean the pot boiled dry and the eggs caught fire, burning down your kitchen.
A large amount of AI to shift slightly forward or backward based on turn signals? No.
How do you plan to advertise it?
I figure a reasonable rule of thumb is that if someone got to the top of some system by maximizing some metric X, where X is the main metric of merit in that system, then they're unlikely to push for the system to prefer some other metric Y, even if Y is more aligned with the stated goals of the system. Pushing for a shift from X-based merit to Y-based merit would potentially imply that they're no longer sufficiently meritorious to rule the system.

To your last point, I think a lot of systems reward ignorance in one way or another. Eg, plausible denial, appearance of good intent, and all other sorts of crap that can be exploited by the unscrupulous.
Amazing, I would love to do a version of this for more niches. Any pointers on how you built this?
> Half a centimeter landing accuracy is not possible, and Bill likely misspoke or was talking about control error.

Maybe the 1/2 cm accuracy refers to the final position of the booster's catch points on the arms after they've closed, after the booster's engines are off, and after the booster settled, and maybe they mean lateral accuracy. I would forgive them for that because that's the accuracy that actually matters here.

If the catch points were off then that might spell disaster, so the catch points' landing accuracy including the help of the catch arms is what matters.
> things like fizzbuzz are still useful

I think you're right here but, to play devil's advocate... isn't there some survivorship bias going on here? I assume you've never tested the negative hypothesis and gone ahead and hired somebody who couldn't program fizzbuzz to validate your assumption.

Copilot for SaaS
Are there any startups building copilots for complex saas tools ? Seems like a genuine problem but I couldn't find anything except CommandBar (which was acquired recently and isn't there on any of its mentioned customers). By copilot, I mean features like taking actions for users and Q&A on the product itself.
> As someone who studied physics and came out with a 2.7 GPA due to studying what I wanted (the hard classes) and not cheating (as I did what I wanted) - I can say that there are consequences to this approach.

I can, too. I wanted to learn, but I also wanted to achieve a high GPA. I had a privileged background, so I got to retake classes after earning Cs or Bs until I got an A, without cheating.

The consequences: My degree took a long time to get, cost more money than my peers in the same program, and I now have a deep-seated feeling of inadequacy.
The issue is most likely cloudflare blocking most the best scraping methods. If the site can be pulled down with eg. wget or curl without a bunch of options that you definitely aren't writing by hand, pandoc can just be used to directly make an epub.
Yes, I use direct IPv6 peer-to-peer connections both outbound and inbound using the delegated prefix.

Even for a changing prefix, if operating a DNS authoritative server for a domain, any changes to the prefix can be quickly and automatically updated in both forward (AAAA) and reverse (PTR) resource records provided the TTL for those records is appropriately short, and thus allow almost seamless inbound via FQDNs. I do this with a bind9 (hidden) master locally that notifies external slave servers operated by a highly available, anycast, DNS service.
is "surface amplitude" vibration? I could see vibration being graphed over time as a wave with an amplitude and frequency. I can't really comprehend the size of super heavy combined with the energy density of just one turbo pump on one raptor engine (let alone 33x2) and then the precision of control needed to catch the whole thing with chopsticks. Not many things do i admit are just beyond me period but this is for sure.

/raptor 3 pumps look like you could hold them in your hands but iirc they deliver over 100k horsepower each.
The Open Source AI definition: Why we need it

> can be circumvented entirely if you use the power in space e.g. in AI-training compute centers also in orbit.

In addition to power requirements and data transfer, I always thought that the main logistical issue with in-orbit computers was heat dissipation. If you have a need for compute in orbit (let’s assume this is true), you’d still need a way to dissipate heat. But this isn’t something that can happen easily in space.

(But it makes me wonder if you could have a Peltier generator attached to a hot chip to remove heat and “recycle” some of that energy back into electricity… not that it would help too much with the other issue with compute in orbit - data transfer)
If my imaginary four-year-old has a fever in the middle of the night, I first phone the nurse-on-duty, and if they determine I need to go somewhere, I see if there's a nearby shared e-vehicle (and in the middle of the night, it will sure be), and use that. Or, like, call an Uber, which might be slightly faster, but for a fever, well...

And if the situation is truly urgent, they'll send an ambulance, which should take less than 15 minutes, and will offer the best care available in that time window anyway.

And I'm absolutely sure the situation is entirely different where you live, but isn't that the real problem then?
The number of people behind CGNAT is huge and rising. It's collectively worth it. And really not that much effort. (If your internal business network is sufficiently entrenched you don't have to change it.)
Agreed. It would be a great option for ground stations on the moon. Lunar nights are 14 days long.

I walked into a B&N in a wealthy neighborhood of a major city. I went looking for the literature section, couldn't find it, and was finally directed to a narrow set of shelves at the end (i.e., the narrow edge) of an aisle. That was all they had.

Why and when did we discard all that literature?
Sonnet 3.5 is the best model for many tasks.
You have no solutions, you have fantasies about turning America into a false vision of France apparently.

I've been to France as well, outside of major cities. Perhaps not as well traveled as you, but I remember seeing plenty of private cars in driveways and on roads as we passed by various dwellings. I doubt they'd take kindly to your suggestion either. Weren't there riots over the price of gasoline not that long ago?

Whatever, be a flat-earther of transportation policy if you wish. You clearly aren't serious.
It’ll depend per person, but I subscribe to around 30 podcasts. For some podcasts (like The NY Times Daily) I’ll skip 29 out of 30 episodes. For a select few I’ll listen to 9 out of 10. For the others, something in between.

Apple Podcasts is the absolute worst for this use case. Even if I listen to all released episodes, I’m still lost to where my unplayed episodes are and what my listening queue looks like. Let alone if I want to exclude episodes from said queue.
Yeah, people who are making claims about social distancing, etc. are wildly leaping to conclusions.

There are a number of more plausible / simpler alternatives. For example: the innate immune system gets activated whenever you have an infection. This is the most primitive form of immunity that you have, and is blunt (fever, snot, generic immunoglobulins, etc.) but effective at warding off pathogens of any sort. It's why you don't often get two different upper respiratory infections at the same time.
Phew! Thank goodness you skimmed it! For a minute there I thought the NGINX developers knew something you didn't.
Good counter points, thanks for sharing those.
They’re trying to solve various issues with harmony. You want to pick a set of notes that produce good harmonies with each other, but you don’t want to pick too many notes. If you “fudge” some notes, which compromises the harmony, you can keep a small set of notes in the octave (like twelve!), and if you’re careful about it, the music will still sound consonant / harmonious when it is supposed to sound that way.

Historically, the older systems were some derivation of Pythagorean or just intonation, which are generated from small integer ratios like 3:2, 4:3, 5:4. If you continue building a tuning system out of these integer ratios, you get weird ratios like 81:80 (syntonic comma) or 531441:524288 (Pythagorean comma); you can then choose to include these ratios in your tuning system (too complicated), stop before you reach them (too simple), or divide up the ratios and distribute them in other parts of your scale. This last approach is called “musical temperament”.

https://en.wikipedia.org/wiki/Musical_temperament

Werkmeister devised a set of musical temperaments in the late 1600s. Alternative temperaments include mean-tone temperament (various flavors) and equal temperament. Mean-tone temperament divides the commas equally apart parts of the octave. Equal temperament divides the commas equally across the entire octave. Werkmeister temperaments divide the commas unequally. This results in some intervals which sound more consonant and some intervals which sound more dissonant, relative to equal temperament. Unlike equal temperament, different keys will have different character.

Just to illustrate a more concrete problem: systems which improve the fifth often require sacrificing the third. Pythagorean has exactly perfect fifths but the thirds are not so good. Quarter-comma meantone goes the opposite direction and gives you exactly just thirds, but the fifths are not so good. Equal temperament is between the two, but much closer to Pythagorean.

If you want to play with it immediately, and you have Logic Pro installed, you can go menu diving into the tuning settings for your project. Other DAWs too. Various synthesizers also have Werkmeister buried in the menus—some brands more than others (I know Yamaha has had them for ages).

NAT64 requires you to have a NAT with a public ipv4 address. Or possibly pay to use someone elses NAT.
Most of this article feels like it's discussing irrelevant methods, you only need GPS to get it close (well for what they're doing they don't need GPS at all, though I'm sure it's used), we have much much more accurate ways of measuring the positions of things from a fixed reference point, 0.5cm deviation on your positional measurement is trivially achievable with optical systems. Why is the author spending paragraphs discussing IMU accuracy when we're trying to line up a rocket with a tower. You care about the rocket's relative position to the tower, you can put your measurement equipment on the tower, you don't need to worry about how accurate your accelerometers are.

I assume they are doing something much more clever/hardened, but you can trivially achieve much greater spatial accuracy with a Vive Tracking Puck for like $100.
Note in terms of sources for this number, lots of articles around 2015 discussing the 95% failure rate. This article is from 2 years later, 2017, and the failure rate was still abysmal: https://abcnews.go.com/US/tsa-fails-tests-latest-undercover-...
Joke aside, I don't think any of those are El Paso or Juarez. Top one is Nogales, the one with the Rio Grande has water in it so can't be El Paso, probably closer to Brownsville.
As I mentioned in the "Tricks for faster samples" [1] section of the article, you can take a sample in two parts: (1) identify the rows in the sample and (2) read the data you want for the rows in the sample.

Only Part 1 requires running Algorithm A and its ORDER/LIMIT logic. And, when you run that logic, you only need to read two tiny columns from the table you want to sample: the weight and the primary key (any candidate key will work). So it looks like this:

SELECT pk
FROM Population
WHERE weight > 0
ORDER BY -LN(1.0 - RANDOM()) / weight
LIMIT 1000 -- Sample size.

This operation will be fast whenever your data is stored in a column-oriented format or when you have indexed the weight.

I trust that you will accept as self evident that column stores are very fast when reading two small columns since they don't make you pay to read the columns you don't need.

So I'll focus on the row-store case. If you have indexed your weight, you basically have a tiny table of (weight, primary key) pairs sorted by weight. If you then run a query that needs to read only the weight and primary key, the query planner can fulfill your query by scanning the index, not the full population table. (The fact that the index is sorted doesn't matter. The query planner isn't taking advantage of the index ordering, just the fact that the index has everything it needs and is way smaller than the full population table. Most modern row-oriented database stores support index-only scans, including PostgreSQL [2] and SQLite [3].)

AI can offload the burden of producing more of something it’s seen a lot of. Including miasma.

AI is much less likely to help you engineer your way out of miasma.

When you automate something, you get more of it. Except attention, you get less of that.

The Alpinist was incredible. There’s a scene where Marc Andre climbs an ice wall, alone, in silence. Just the crackling of the ice, his breathing, and the sound of his icepicks and shoes. Made me understand the “why” - without any words.
There is a disconnect between what most people imagine spectacular failure to be (probably something publicly humiliating and/or financially ruinous) and this, where even a spectacular failure when running a marathon wouldn't be noticed unless you told other people about it.

This is an article about computer software being used to surveil civilians. (Many people consider government surveillance to be a freedom issue.)

This kind of concern has aligned with the EFF's mission for as long as it has been around.

I don't mean to disparage this particular instance at all, as it seems pretty great. But I wonder if the rise of llms is going to make scams that sounds a lot like this much easier in the future. I think at the moment it's hard to make something really sound like a particular author without a lot of work, but that will probably change in the future.

So you would build a solar array in space at enormous cost and then need to truck or fly in a receiver, and build it. Versus trucking and building a solar plant with batteries on site. I still don’t think that it’s ever going to make sense.
> among the 7 largest mass extinctions in the entire history of multi-celular life on Earth

I strongly dispute this. Mass extinctions in the fossil record are typically measured at the family level, yes? Most of the then-extant species wouldn't even have been recorded.

If we were in the equivalent of one of the major mass extinctions it would be a "put your head between your legs and kiss your ass goodbye" situation. We wouldn't be worried about the survival of uncommon animals. We'd be worried if rats were going extinct.
You're right. When interviewing for a team that writes mostly in C and assembly (assembly for various different ISAs), we're not going to hire someone who claims to know C and fumbles through some basic problems and can't reason about hardware in the slightest.
Oop, this is me. Thanks for the comments everyone, I've reworked my article to be more coherent.

I've been saying a bunch of similar things for a while now. I sometimes refer to it as being past a Poe's Law Singularity and good satire is hard/impossible/dead. Poe's Law examples (someone taking satire as serious surface level only takes) are too easy to find today, including in the very names of modern startups and corporations. RIP satire, you were a good friend once, and so it goes. It's possibly a good thing Vonnegut did not survive to see this world on the other side of the singularity. (Or it is possible it only happened because too many writers like Vonnegut passed away out of this timeline.)
This talk is FANTASTIC and has been an inspiration for me for years as well. Highly HIGHLY recommend it.
Example IaC for AWS Global Accelerator
This article is a little schizophrenic. It calls the cameras "wasteful" and "snake oil", yet the referenced NBC article calls them "a crucial tool". It quotes reports about failures of old systems from Boeing and General Dynamics, then implies without evidence that the same criticisms apply to the newer Anduril "AST" systems. There is no allegation that the AST systems are broken at all.

It has signaled different things over the years, and generally more than one thing at a time. I think it will still signal things to employers so that having a college degree isn't going to be become useless, but it will become less sufficient. Things like internships, references, and significant take home projects/complex and long interviews will now be needed to vouch for skills in a way that a degree mostly covered in the past.

1. build a co-op/intern program and hire out of that exclusively for junior. It's like an extended, two-way interview or try before you buy for both sides.

2. screen for passion and general technical competency above all else. You're going to make arbitrary decisions & restrictions (ex: we're only hiring from these 3 schools) which is fine, then work within those constraints. Ask about favorite classes (and why), what they've done lately or are excited about, side projects, OS contributions, building/reading/playing. The best intern I've hired lately answered some high-level questions about performance by building a simple PoC to demo some of their ideas, with React - a technology they didn't know but that we use.

3. recognize some things on the hiring side that from the hunting side don't make sense or are really annoying: you're playing a numbers game, hiring is a funnel, it's better to miss a great hire than go with a poor candidate (i.e. very risk averse), most hiring companies are at the mercy of the market; they hire poorer candidates and pay more, then get very picky and pay less. In a tight market you can't do much internally to stand out, and when lots of people are looking you don't have to.
I’m enjoying Castro showing us they’re actively developing again vs telling us. Even the Halloween app icon serves that purpose.
Dramatic. :) For the potential fandom side of a dev board (other than companies being a fan of not paying for ARM licensing), a software person's questions:

* Does it work entirely with mainline Linux kernel, including drivers? Which version?

* Are all the onboard devices open firmware?

* Is it free of unwanted processors like Intel ME and AMD PSP?

* Is that a daughterboard? If so, is the daughterboard suitable as a module in production? If so, what is on the main board, other than connectors and passives?

* Is "full-size" PCIe 3.0 slot actually x16? (Hard to see the connector at 22s in the video.)

* How much RAM, and is it ECC? Upgradeable?

* The GPU is only suitable for, say, 1080p or 4K video playing, not for general-purpose or AI compute, correct?
But all of these were policy choices over the past decades. We very much could have invested in public transit and built housing, but instead we decided most humans should have a car to go about daily life. Which, if we're optimizing for sending money to car, oil, and healthcare companies, I guess is a good strategy.
There's "aficionado", though that feels a little pretentious
Erm, you have to practice, prepare, whatever in order to do anything apart from sitting on the couch. I participate in motor racing, which is about as type 1 fun as it gets. Seriously, racing other people at the limit of your ability for a whole weekend is about as fun as it gets. But goddamn is there a lot of preparation that goes into building the car, wrangling the team, etc, etc. Yea, I like building the car, but I'd be lying if I said I was absolutely stoked about rebuilding two engines that we blew up in the last race. And all this stuff takes time, and that time has to come from somewhere, which is a sacrifice.
