Wow, cool, you actually tested it! And an effective test too.

Stepping back and forth throughout the frames (using mpv), the flash clearly enhances several spots of localized brightness where contrast pops out into clear relief.

The effect is clearest at the very bottom of the image which goes from "shadow blob" to "adequately discernible", but I think the area just above that (the 3rd vertical quarter of the image) is most interesting; the detail visible in frames 24-29 (immediately before 00:00:01 / 30.030fps) is excellent, and that's with the flash LED at peak brightness.

Flash synchronization would be effectively impossible to achieve (the camera would need to stream LED status information inside each frame), but achieving such synchronization may provide no net gain, even with "LED is on" information available, both because the exact point the hardware says "LED is off" will not necessarily correspond to the exact moment in time the light decays to zero (based on 1/960 = 1.0416 milliseconds per frame, the video suggests it takes apparently 2 frames or ~2.08 milliseconds for the light to decay), which will never be the same as the flash sends light outwards into arbitrarily different environments. I can't help but wonder if calibration references for everything from Vantablack to mirrors would be needed... for each camera sensor... and that there would then be the problem of figuring out which reference(s?) to select.

Staring at the video frames some more, two ideas come to mind: 1), analyzing all the frames to identify areas of significant difference in brightness, then 2), for each (perhaps nonrectangular) region of difference, figuring out the "best" source reference for that specific region. As an example reference, I'd generally use frame 13 for most of the image, and frame 44 or so (out of many, many possible candidates) for the bits that, as you say, become float64 1.00 :). Obviously a nontrivial amount of normalization would then be needed.

I'm not aware of how you'd do either of these neurally :) but the idea for (1) came from https://en.wikipedia.org/wiki/Seam_carving (although just basic edge detection may be more correct for this scenario), while the idea for (2) came from
https://github.com/google/butteraugli which "estimates the psychovisual similarity of two images"; perhaps there's something out there that can identify "best contrast"? I'm not sure.

Trivial aside: I wondered why mpv kept saying "Inserting rotation filter." and also why the frame numbers appeared sideways. Then I realized the video has rotation metadata in it, presumably so the device doesn't need to do landscape-to-portrait frame buffering at 960fps (heh). I then realized the left-to-right rolling shutter effect I was seeing was actually a bottom-to-top rolling shutter. I... think that's unusual? I'm curious - after Googling then reading (or, more accurately, digging signal out of) https://www.androidauthority.com/real-960fps-super-slow-moti... - was the device an Xperia 1?

(And just to write it down for future reference: --vf 'drawtext=fontcolor=white:fontsize=100:text="%{n}"' adds frame numbers to mpv. Yay.)
I think it's telling that in this conversation so far the one thing not mentioned has been the I-word: Ideology. Though there has been a bit of the C-word: Class.

Talking about what's best for the country is _by_its_very_nature_ s political, whether we choose to acknowledge that or not.

"Politics (Greek: Πολιτικά, politiká, 'affairs of the cities') is the set of activities that are associated with the governance of a country, state or area. It involves making decisions that apply to groups of members and achieving and exercising positions of governance—organized control over a human community ...

... In modern nation states, people often form political parties to represent their ideas. Members of a party often agree to take the same position on many issues and agree to support the same changes to law and the same leaders. An election is usually a competition between different parties"

Does any platform ship with ack? I wouldn’t expect any mainstream one to. (And for any platform inclined to add useful utilities, I’d suggest ripgrep rather than ack, as it’s way faster, and superior in almost every regard.)

Table Plus works on macOS.

I disagree about the UI. Table Plus when connecting to a DB will mark the offending parameter red to let you know what credential isn't right e.g. host/port/key I've found this very helpful.

Sequel Pro is free which you didn't mention and Table Plus has a fee.
Interesting distinction between "capitalism" and "free markets".
>The only thing that has prevented riots and general instability of governments is mass bailouts

Yes. This is more to the point that the current economical doctrine is very much misguided.

What I was of course talking about is how positive the situation is for the biosphere.

It's way more grim if the biosphere can not support us anymore. The fact that human political systems cause mass death, poverty and suffering is not news.
> The UK will not lose its place on the UNSC for doing the bidding of the US.

Predicated on the US still being involved in the UN though? Which I wouldn't rate as a certainty any more - they were ignoring the fees for years and now there's an active "NIH" Government determined to pull out of every cooperative endeavour...

Fully fledged totalitarianism isn't overthrown by revolution, a worldwide totalitarianism isn't some kind of necessary stage before universal peace -- it would rather make peaceful, dignified relations of people to themselves and another completely impossible, and maybe for good.

> At this point we find ourselves confronted by a very disquieting question: Do we really wish to act upon our knowledge? Does a majority of the population think it worth while to take a good deal of trouble, in order to halt and, if possible, reverse the current drift toward totalitarian control of everything? In the United States and America is the prophetic image of the rest of the urban-industrial world as it will be a few years from now -- recent public opinion polls have revealed that an actual majority of young people in their teens, the voters of tomorrow, have no faith in democratic institutions, see no objection to the censor­ship of unpopular ideas, do not believe that govern­ment of the people by the people is possible and would be perfectly content, if they can continue to live in the style to which the boom has accustomed them, to be ruled, from above, by an oligarchy of assorted experts.

It's not that we now have less risk for the things that were described by thinkers in the 20th century, it's that we became more complacent and cowardly, less ambitious and more comfortable, and are rationalizing it. We don't know more, we just are less able. We don't rise to the occasion, we pull it down into the gutter with us. This is the whimper our betters have seen coming.
> Because the main purpose of Harvard and other elite schools like it is to pick out the best ~18 year olds and set them on the course to be leaders in business, government, law, and other areas. Harvard isn't Harvard because they're better at education. Harvard is Harvard because they get the pick of the litter. Extending their enrollment to a million doesn't mean we get a million more elites.

It doesn't even do that. Harvard doesn't pick out the brightest 18 year olds to become future leaders. It picks out the most competitive kids who care about going to a place like Harvard.

If all you wanted to do was prove your intelligence, an IQ test is much cheaper and quicker.
Yeah, at one place I worked at, an employee was banned because she kept trying to remove certain information about the organization from Wikipedia. I was a little amused, but she very nearly got our whole range banned.

I find coordinated efforts to edit Wikipedia -- by whoever and whatever "good" their reason to be -- fairly creepy. It's like a lot of little Ministry of Truths running about the place trying to massage reality.
Drop me a line, help me get these PPEs in clinician hands.
He could call Harvard and donate a bunch of developers for a year to build that system which could educate a million 18 year olds. Harvard will certainly take his call.

He couldn’t fund all the hyper efficient factories for the country, but he could build one.
But not "text books, clothing, jewelry and the like". As stated it sounds delusionally optimistic to me.
Where is your hacker spirit?
How do "surveillance" drives fit into that? They're supposed to be special for being reliable with a lot of writing, several orders or magnitude more the drive's capacity. Apparently normal hard drives aren't reliable enough for recording CCTV footage.
Wow. That'd be quite the fuck up. I mean, maybe they were sampling bat caves, to check for SARS-CoV-like viruses. Which would have been prudent. But then maybe they were sloppy, so many died, and it escaped the lab.

If you could find sources, that'd be an amazing story!

I've had this for a while and I noticed at least two problems on my mac:

1) It made the history command run much, much slower (I have HISTSIZE=100000)

2) Dates tend to reset to a uniform but meaningless value. I think it's related to OS reboots.
But if this was a coordinated misinformation campaign, why not just use a VPN or dynamic ip?
>We don't have it because building these things requires long term investments and folks like Marc and his investors are not interested in long term investments. America's corporate leadership has pursued elastic labor forces with minimal training (and therefore minimal flexibiity), outsourced manufacturing (and therefore long lead times on domestic production) and minimal redundancy in infrastructure because these rich folks think, plan and act on a quarterly calendar. We don't build new homes because homeowners like the value of their goods protected by intense scarcity. We don't compete with China because capital sees value in redundancy only with the framework of internal corporate prognostication, not as an actual net good when considered in a system

I would very much like the author of the essay to read "Of Flying Cars and the Declining Rate of Profit":

>With results like these, what will the epitaph for neoliberalism look like? I think historians will conclude it was a form of capitalism that systematically prioritized political imperatives over economic ones. Given a choice between a course of action that would make capitalism seem the only possible economic system, and one that would transform capitalism into a viable, long-term economic system, neoliberalism chooses the former every time.

> "I'm going to force you to get tested, despite you having no symptoms" is political anathema

This seems less extreme and more palatable than "I'm going to force you to stay home and lose your job, despite you having no symptoms" which is very nonetheless popular right now.
I'm not the first person to have thought about group variations. :) Here's an old paper (which also highlights how this important fact is omitted in a lot of analysis): http://web.eve.ucdavis.edu/sschreiber/reprints/Moving_beyond...

R0 is before interventions AND is environmentally related. Wuhan & NYC covid has way higher R0 than California Covid because of higher density/public transit usage. Additionally, effective R was already well below R0 by the first week of march (pre-lockdown) because of heavy (mostly voluntary) measures already in place. (WFH, more washing of hands, avoidance of mass gatherings, etc.)

Finally, I'm speaking a bit tongue-in-cheek calling it the "essential worker herd immunity plan". I doubt public health officials, rushing to do something, explicitly realized this would happen -- but with a bit of thought [1], it was a pretty expected outcome. [sort of how nursing home outbreaks occurring when we didn't - and still don't -- quarantine employee or give them heavy PPE was expected)

[1] It's pretty unfortunate there isn't a public or academic comment period to evaluate the SIP orders (after issuance) and almost no useful data being given about cases. There's a lot that doesn't make a lot of sense -- important restrictions missing and unnecessary restrictions present. My biggest pet peeve is allowing babysitters to come to any workers' houses, but it being disallowed to send your kid to a babbysitter's house, when adults are more likely to transmit than children.
Yes, I find that solution much simpler.
So that they can take over the dominant market position, eventually using the exact same tactics to keep entrants out. Anything less would run afoul of shareholder primacy so unless VCs take an active role in promoting ethical behavior from their portfolio, those words are empty as this blog post. Anyone who wasn't born yesterday knows that human beings won't do something that is in direct opposition to their interests (the exceptions to this rule became nurses and doctors and social workers, not VCs) and without an honest to goodness change in laws, reasonable people know that VCs won't change their behavior. Since most portfolio companies are in competition with someone - a fact almost every investor in the industry is cognizant of - anything short of actually spending money on lobbying to change laws and promote their enforcement is an empty gesture.
Which I'd assume is part of the reason people are choosing that art style for articles - when you don't know what people are going to be viewing your image on, a limited bold colour palette with bold shapes is probably a fair bet for "yep, still works" on most devices.
Noice find. TBH, on my T480, I only use the trackpad because the pstick is a smallish, delta-only pointing device that takes too long for me... it's too much like moving a cursor around with a joystick for my taste. YMMV and there are different cursor-moving religions.
Huh? They haven't solved it, anymore than reading a thermometer "is to solve" climate change. No need to repeat propaganda.
But that's a moot point because it's simply impossible to do a hard lockdown in an open society like the US. There are too many essential activities, and the government lacks the resources to strictly enforce orders.
The flu is seasonal, the first wave died down during the summer and the second wave started in the fall.
Yeah, but so is nearly everything else. Money, sexuality and gender, architectural designs, military tradition, the list goes on without end. Nearly our entire society is a communicable memecomplex, and additionally, nearly every meme is logically incoherent, or at least logically unfounded.

By the very implied claim that you make that mental disorders exist, you also imply that there is such a thing as ordered mental states, correct patterns of thought, and healthy logical reasoning. This is a bold claim! You would do well to have less black-and-white reasoning.
italy did this in a small town, testing weekly, by week three 80+% showed symptoms, and concluded they would all eventually show symptoms.
Depends on which method is utilized. “Ping ponging” would have issues as you’d run into all the problems of all of them.

Depending on how the “blending” is done and whether the algorithms are truly independent of each other, combining them is definitively more secure than any of them individually. The Linux kernel let’s you do this through writing to /dev/random. The written bytes get added (in part) to the entropy pool.

Yup, I agree. I just can't really see how it's possible to incentivize this at all. To _not_ pursue regulatory capture seem to require an altruistic mindset, which I'm not naive enough to expect from businesses.

In Sweden we luckily still default to making almost every government document, including e.g. all police investigations that reaches the courts, public for all who requests them. It requires special circumstances to make them confidential and nothing that can be done in the loose manner you're describing.
Sure, forensics accuracy isn’t something I hugely care about, i do have some shell sessions that span days so having an indication can be handy.

If I did, It’s also possible to get amount of time a command required to complete. Based on that execution time in conjunction with the timestamp of the next print of PS1 it would be easy to deduce the time when a line was actually executed, rather than when typing of the line began, but at that point I’d probably just record my screen to track any harder to determine behaviours.
Ask HN: Where to publish Rust command-line tools for easy use?
I just made a small Rust command-line tool, and I'd like to distribute it.

What I'm most familiar with when it comes to publishing CLI tools is NPM. However, since Rust requires a build step I don't really feel like crates.io is set up for that on its own. There exist OS-specific package managers like apt and homebrew, but I'm not super excited about the prospect of going around and maintaining separate publications on each of those, especially since I don't even use Linux really. And of course Windows would be left out of the loop, even though the tool should build and run just fine there in theory.

I wish there were a CLI-focused package manager for Rust tools that would just download a tool's crate from crates.io, do a release build for the local architecture, and add it to your path. Does this exist (if not it could be my next project...)? And if not, what's the conventional practice here?

Edit: I just discovered the "cargo install" command, which is basically what I described above: https://doc.rust-lang.org/book/ch14-04-installing-binaries.html. I'm still wondering about convention, though. Do people ever publish runnable crates on crates.io and call it a day?
I really appreciate the calm background music.

I think background music is important. Especially on such long explanatory videos but often it becomes a reason for me to turn off a video if the music becomes to aggressive.

"If the top speed is five miles per hour, so be it."

You are not really testing though. The whole point is to build a machine that can go the speed limit. You can test all you want at 5mph, but let me assure you, most of the real issues will show up when you go 45 in the real world.

If you’re that bad, they should have let you go. So, you’re probably not that bad, or they’re not very well run and are lucky to have you.

Either way, try to change your situation.

If you want to make things work where you are, ask your manager to set up some sort of mentor for you. (Either the manager, or someone else.)

Frame it positively: You want to improve so you can start to move up in the team (or something like that). At least you will show you’re motivated to improve, and not content slacking off and drifting along.

Living in New Jersey, gives me a front row view of crumbling America. I grew up in India and have no illusions of American infrastructure being third world standards. I'm taking about houses people live. I've been trying to buy a house I like for past 4 years. I've been to open houses in many small towns here. Town after town, I see 60, 80 even 100 years old houses, that are beyond repair. They all sell at upwards of 400K. I talked to realtors about new houses. They said people are afraid to repair or rebuild houses. If you rebuild your house from ground up, the town would reassess their property taxes and often charge 1000 to 1500 dollars a month of a medium sized family home. My friends in India earning much less than me live in far better and newer houses these days.

I think it's the lack of political will in America to make our lives better. You let your politicians (especially at local level) confine you to essentially urban slums rather than let you build a dignified life with your hard earned money.

Milton Friedman did his thing from a university founded by John D. Rockefeller in a Department of Economics that is now named for Kenneth C. Griffin of Citadel Securities. I think it's safe to say that capital does spend on its policy interests, and quite effectively.
