They're a bit of a bilingual mess.

Did they start out with German table names and decide to give new tables English names at some point?
I think this sentiment only applies to certain products. A software like Slack can get away with being good enough. Self-driving softwares like Tesla's FSD? Not so much. There are certain engineering solutions that aren't viable without being perfect. People expect them to be perfect.
Just like anyone else, Musk is right some times, wrong at others, and averages out as kind of OK. He's very good at attracting investment though, and SpaceX has been executing really well.

> How come people who hired bunch of grannies to knit a nav computer memory got to moon without loosing a single rocket.

NASA did lose a good couple rockets. They also lost the Apollo I and its crew even before it flew, as well as a number of near misses that were recovered by the brilliance of astronauts (Armstrong saved the day TWICE) and ground crews alike. They also lost two shuttles precisely because they couldn't afford bad news from propagating back to the senate.

> And now loosing 3 rockets and still not orbiting is an amazing achievement?

NASA-style development is very risk averse, which is natural, as it's primarily a government agency tasked with keeping the aerospace and rocket industry happy and healthy, and preventing talented engineers and scientists from moving to Europe, India, Russia, or China. Or North Korea.

NASA can't afford to lose three rockets, because each small piece is expensive and exhaustively simulated and tested before being assembled and launched. It does that to advance our theoretical understanding of how to build spacecraft.

SpaceX iterates quickly and cheaply, blows up engines, rockets, tanks, launch pads and anything else, because it makes them cheaply and use them to learn what NASA does by careful simulation and lab testing.
Yeah. Sorry for the wording. Not a lot of people are eager to converse with my 6am head.

> who re-christens her Aurora

Although there was probably a significant element of chance (how many naval ships were in St. Petersburg harbour at the time?), you have to hand it to the Bolsheviks: using a cruiser named "Dawn"* in latin, to signal a revolutionary attack, was a majorly literary flex.

* her greek epithet being rhododactylos, "red"-fingered, just layers on the allusions.

I think it dovetails with the Administration's recent pausing of outlawing menthol cigarettes which has been reported as adversely effecting African Americans. It's blatantly political, which giving the people what they want and all, but it's disingenuous when these things only occur at election time. The President could have done this on day one.

> In July, August, and September of 2021, Intertek performed tests
assessing the PFE of various assembled Zephyr prototypes. In each test, the assembled
device failed to perform to the N95 standard of 95% or greater PFE. Figure 13, infra,
depicts the best results ever reached for the device in testing: as documented in
Intertek’s August 13, 2021 report, the device reached a maximum PFE of 83.2% with
the fans off and 86.3% with the fans on, and frequently tested much lower. The mask
did not come close to consistently reaching a PFE of 95%, the level of protection
characteristic of an N95 mask.

> Thus, while Razer’s CEO was claiming that the Zephyr was a more
comfortable, reusable N95, see supra ¶¶ 46-47, internal communications reveal that
Defendants knew the mask could not provide the level of protection offered by an N95.

There's a quote from Michelson that "the future truths of physical science are to be looked for in the sixth place of decimals". Many misinterpret this to be a statement that 'there's nothing new to be discovered', but his actual point was that discovering new science requires rigorously searching out and understanding even small deviations in measurements.

Here's the full quote:

"While it is never safe to affirm that the future of Physical Science has no marvels in store even more astonishing than those of the past, it seems probable that most of the grand underlying principles have been firmly established and that further advances are to be sought chiefly in the rigorous application of these principles to all the phenomena which come under our notice. It is here that the science of measurement shows its importance — where quantitative work is more to be desired than qualitative work. An eminent physicist remarked that the future truths of physical science are to be looked for in the sixth place of decimals."
That's definitely not the main problem. Risk of intracranial hemorrhage/strokes and other complications make it problematic.
You mean we aren't doing realtime raytracing yet? Sad.
It's a fact Musk is neither as brilliant and infallible as his fans say, nor as clueless as his detractors would like him to be. He's smart and arrogant, a dangerous combination that SpaceX, it seems, grew defenses against.

Folks in other comments have answered this pretty well. Over the past couple of years, I've talked to many companies and individuals who have greatly benefited from autoscaling on k8s. Generally, it has helped in these areas:

1. Obvious case: if you run your environment on cloud providers, it can significantly save costs and improve throughput.

2. It's not just about autoscaling workloads, but also about managing batch jobs (K8s Jobs) that are triggered by events or custom metrics on demand (you can think of this as a CronJob on steroids).

3. On-prem solutions: You're right; you can use the resources you've already paid for. However, by enabling autoscaling, you can also improve the distribution and utilization of those resources. In large organizations, it is common practice for individual teams to be treated as "internal customers" with assigned quotas they can use. Autoscaling can be helpful in these scenarios as well.

If you are interested in the area, I've given several talks on K8s autoscaling, for example, our latest talk from KubeCon: https://sched.co/1YhgO

In Kazakhstan, when a phone is used on a mobile network for the first time, the IMEI of the phone gets locked to that mobile network and that sim card. When you buy the sim card, they photocopy your passport/ID card.

No other sim will work in it until you take that photo ID/passport to the mobile companies office to have it unlocked. The photo id (even if expired) becomes the unlock code for the phone.

Made phone theft drop to pretty much zero.

Also booze is really easy to make. Marijuana is hardly difficult but if you ain't got any plants somebody has to smuggle them to you, whereas if you've got a bunch of say, apples, or potatoes, or berries - which are just food - the only thing that prevents you from having booze is constant oversight to ensure you don't allow the food to be converted into booze.

I can see tobacco becoming effectively a Schedule III type substance, made only when it is deemed necessary for some reason and not generally available - New Zealand tried to set off on that path, the UK is attempting it now, unlike booze (or marijuana) which has a population of people who say "Hey, that's fun, don't take that away" the smoker are almost all against smoking, they see it as an unpleasant mistake they made rather than a choice they're glad to have taken.
In what way is it useful? What value is being provided? In my experience it requires constant supervision and readiness to intervene at any moment. There are plenty of reports and photos of it running wheels into curbs with little time for the driver to react.

Given that, while using it you do not regain any time or attention that you would have otherwise spent driving. That doesn't mean it isn't impressive. A car that can drive itself like a 15-year-old on their first outing with a fresh learner's permit that needs constant coaching from a parent or instructor is very impressive, just not useful.

I will say that in clear conditions on long highway trips, basic Autopilot does have utility. It does allow you to divert some attention from keeping the car between the lines and matching the speed of the car in front, and use that attention to keep an eye on the large traffic picture, and arrive to your destination slightly less fatigued. Using FSD on city streets seems like the opposite of that to me, an increase in stress and workload that currently provides no practical utility.
Not seriously suggesting it, but what if the cab was easily swappable & the underlying truck was semi-standard? Still similar issues of ownership but at least truckers can bring their home with them, which seems to be important.

Silly yes. The 90's vision of the skateboard platform has stuck with me a lot. I'd imagined rolling lounges & other passenger vehicles cabins being a way to start decoupling the car, reducing the number of batteries motors and wheels that a town or city had to own in net. The usage cycle of trucks is a lot higher, and the swappability just for sale of switching batteries seems silly, but I couldn't help but see at least one of the core problems of swappability being solved by disaggregation the compartment from the rest here.

Schedule 1 means illegal under (nearly) any circumstance, commercial dispensaries fall under “any circumstance.” Drug scheduling is just a tiered system for classification in order to determine which rules to apply to its sale, distribution, and possession of the substance.

It's what artists do to lie to themselves so their entire life doesn't seem like a waste of time. I went from music to tech. Art is full of completely delusional hacks.
A couple of thoughts:

First, great job on the readme! One way you could improve it is by expanding on the "Caution" section. What's written is the beginnings of a threat model, but it could be improved by being more explicit about which attacks this system does/doesn't defend against.

> The only security property that disk encryption (and this package) provides is that all information such an adversary can obtain is whether the data in a sector has (or has not) changed over time.

I think the adversary learns a bit more than this. Randomized encryption would provide the above probably, but the _deterministic_ scheme that's used here will let the adversary learn not only whether a sector changed, but whether its value matches what it was at a previous point in time.

How does this translate into the security of the database, itself? Seeing what blocks have changed might reveal information about what data has changed. Let's consider a security game where I (the adversary) get to submit sql queries, and then learn which blocks on disk has changed. After this initial phase (where I can learn where data is stored), I submit two different sql queries, you pick one of them at random and run it, and then tell me which blocks have changed. I win if I can guess which sql query you picked.

Suppose I submit queries which each insert into a different table. Because the tables are stored separately on-disk, it'll probably be pretty easy for me to distinguish them. But okay, that's still count-ish/size-ish, and maybe out of scope.

What if I submit two queries which each insert different values, but into the same table. Further, let's say that this table has an index. Based on which pages were written to, I can now learn something about the _values_ that were inserted, because different values will write into the index in different places.

Now, it's completely valid if the threat model says, "if you can see more than two copies of the database file, then all is lost." However, I think it'd be worth translating the current write-up of the threat model into the implications for leaking the database. For more examples of attacks based on seeing what indices/sizes changed [1] and [2].

Is it valid to pad the sqlite file to a multiple of the block size? Does sqlite ever call truncate on a non-block-aligned size and expect any truncated bytes to be fully removed?

What are the atomicity requirements for a sqlite VFS? SQLite, in general, is supposed to not get corrupted if power were to be yanked mid-write. However, because this VFS writes one block at-a-time, the computer dying mid-write could corrupt more bytes around the write position than would normally be corrupted if the the standard VFS was used. It's possible this is a non-issue, but it's worth considering what contract sqlite has for VFSes.

This is a perfect example of a choice that a developer makes to suit his/her personal preference and environment, believing that everyone does (or should) use their computer the same way. Which is sadly becoming a more common trend.

I like the idea, but I don't think it should be on by default. The rest of us have just used root-specific shell prompts for the last few decades or so.
> Rabbit has said the device will be able to learn any app, if you teach it.

We're building this over at https://github.com/OpenAdaptAI/OpenAdapt. OpenAdapt learns to automate tasks in desktop apps by observing human demonstrations.

Early demo: https://twitter.com/abrichr/status/1784307190062342237 (more coming soon!)

The demo is overly simplistic to keep it short -- it also works with arbitrary applications and operations.

Also, we're open source. Contributions and feedback are welcome and encouraged :)
> You're always welcome to write an alternative if you don't think systemd's direction is correct.

They actually exist. Namely OpenRC and s6 as the main competitors to the core systemd functionality (init). There exist other alternative projects for the other components of systemd as well.

My complaint is that they are adding another tool that depends on their core software in an attempt to replace a portable, well established tool in a non-drop-in way.

This is a consistent pattern with systemd that feels very embrace-extend-extinguish-y and it does nothing but increase the cost involved in keeping code portable between different platforms.
I believe that case is not resolved yet.
One type of foundational infrastructure got a few years ahead of its applications? Oh, the horror. The horror!
my experience with world-renowned experts in pure mathematics is that they are much more careful than the average bear to explicitly qualify inaccurate things as inaccurate, because their discipline requires them to be very clear about precisely what they are saying

discontinuity of a function at x does not, according to the usual definition of 'continuity', require the function to have a value at x; indeed, functions that fail to have a value at x are necessarily discontinuous there, precisely because (as you say) they are not continuous there. https://en.wikipedia.org/wiki/Continuous_function#Definition...

there are other definitions of 'discontinuous' in use, but i can't think of one that would give the result you claim

Useful enough that it should be an OS-level standard feature, imho.

Unix-like OSes allow mounting disk images to explore their contents. But there's many more file formats where exploring files-inside-files is useful. Compressed archives, for one. Some file managers support those, but (imho) application-level is not the optimal layer to put this functionality.

Could be implemented with a kind of driver-per-filetype.

You mean aside from the anecdotal evidence from 35 years of being the son of a professional dance costumer (ballet, jazz, modern, and classical), and brother of another professional ballet costumer (ballet, jazz, modern, and classical)? And both have worked with a variety of very large and notable dance companies across the western US? Or about 17 years now observing the gender imbalance in dance schools that my sisters (and now daughters) attend. Or the entire fucking genre of media that clearly shows that gender imbalance (seriously, Billy Elliot's central conflict only makes sense in light of this very real and very sustained phenomenon)?

Ok.
https://datausa.io/profile/soc/dancers-choreographers#gender...

There's a subsection about educational levels of professional dancers, and the gender imbalance is persistent between high-school educated (so only private dance instruction) as well as college-educated professional dancers.

I found similar statistics in Australia.
To be clear there’s a distinction between the quality of the results and the determinism of the results. If a low-precision LLM is wildly stochastic but the variation is mostly linguistic rather than factual or deductive (e.g. coin tosses on synonyms or presenting independent facts in a different order), then there’s not really a contradiction.

AFAIK the determinism side of floating-point precision hasn’t been well-addressed, but it’s been a while since I skimmed those papers.
Such a needlessly negative article. PCIe 5.0 is early, peripherals are scarce-to-non-existant, and existing rigs are not infinitely flexible. Otherwise, it all looks pretty good to me. Even buying one of those may prove worthwhile as new graphics cards and SSDs are released.
Heating the donor by exposing it to sunlight while shading the receiver should provide some pressure differential for no added power. Gentle rotation would start with the center of gravity wihin the donor, but as the transfer goes on, it'd move to the middle of the two rockets and stop the transfer at that point.

Relevant case:

Wickard v. Filburn
United States Supreme Court case
Wickard v. Filburn, 317 U.S. 111, is a United States Supreme Court decision that dramatically increased the regulatory power of the federal government. It remains as one of the most important and far-reaching cases concerning the New Deal, and it set a precedent for an expansive reading of the U.S. Constitution's Commerce Clause for decades to come. The goal of the legal challenge was to end the entire federal crop support program by declaring it unconstitutional. An Ohio farmer, Roscoe Filburn, was growing wheat to feed animals on his own farm. The U.S. government had established limits on wheat production, based on the acreage owned by a farmer, to stabilize wheat prices and supplies. Filburn grew more than was permitted and so was ordered to pay a penalty. In response, he said that because his wheat was not sold, it could not be regulated as commerce, let alone "interstate" commerce. [Wikipedia](https://en.wikipedia.org/wiki/Wickard_v._Filburn)
Well `-u` refers to the unit file, so I would start with `sudo systemctl status` which lists the status of active unit files. I bet I could find the unit name I'm looking for there. If not, then `sudo systemctl list-units` should have it. (and you can grep the output of both)

Systemd and Journald are less opaque than I used to think. Even if you don't want to learn the commands, all of its unit files (and the relationships between them) are available through the filesystem. Most of your unit files will be in `/etc/systemd/system`, and the active relationships between units are expressed through soft links.
> For a computer to support PCIe 5.0, it needs one of two things, though preferably both.

So whats the second thing? It's never mentioned AFAICT. Assuming they meant in addition to PCIe host controllers on your CPU die (though could be in a south bridge or whatever) you need a PCIe 5.0 device?

The rest seems to complain about higher power consumption and heat. This is data center shit anyway so power and cooling aren't big issues there. Given enough time these issues will be fixed once consumer vendors starts caring enough to fix it. Or not. Who cares.

> Another concern is that TikTok’s algorithms could be influencing its users in ways that might benefit China. I guess I can see this, but I’m not sure.

I think this is the heart of the issue. Ironically, I think it didn't necessarily help TikTok's case when they showed a message to their US users asking them to contact their legislative representatives, and that's exactly what they did:

https://www.engadget.com/tiktok-is-now-asking-users-to-call-...

So Congress got to experience, first-hand, an example of TikTok's power to influence Americans' behavior, which is probably just the thing they were being warned about by national security professionals.
