What's the best way to learn color theory? Like actually, properly learn it? I consider my interest in TV/Movies to cross over into the enthusiast category, and I work with medical images and video (compression mostly). I've spent time with the basics, and have recently started reading about BT 709 etc., but am unsure how best to really dive-in to color theory headfirst
The definition of "used" is approximately "delivered to a customer". Doesn't even matter if they returned the box unopened, and got a refund; you still can't sell it as "new".

And, no, I'm not speaking of a "warranty." A warranty means "we'll fix it if anything breaks over a certain time period, perhaps with a refurbished part". That's different than "we'll replace this particular part with a new one as soon as we can, even if it's still working, to make sure you get the entire expected MTBF (as that's typically much longer than the overall warranty for the whole device)"

It's also wrong to think of used chips being as good as new. Yes, you avoid "infant mortality" (though that seems to be less of an issue than it used to be), but how do you know what environment the washing machine was run in? Thermal and power shocks decrease the lifespan, never mind humidity and static electricity. And even if the environment had been perfect, what about electromigration?

That's exactly the reason you can't put used parts into a device sold as new. If you still disagree with this regulation, you're best advised to take it up with the FTC rather than blithely choose to ignore it.

It sounds like it wasn't the exercise itself that was sabotaging you, your comment about muscle pain makes it sound like you weren't allowing for proper recovery time between workouts. That's just as important as the actual workout.
In practice, programs crash when they receive a null pointer from malloc (either through throwing an uncaught exception, or through `if (!ptr) { abort(); }`, or through dereferencing a null pointer). So even if your solution was realistic, it would just entail killing a random process, and it would prioritize killing an essentially random process. When you reach OOM situations and need to kill processes, there are probably better heuristics than "kill whichever process happened to allocate memory after we ran out".
It wasn't the only reason, but -O0 was a contributing factor. -O2 alone improves things, but doesn't bring the frame rate in DDD up to 30
I see little distinction in practice between "I trust my government" and "I trust my corporations", since the advocates for "limited government" in the US favor unlimited corporate power to the extent that corporations effectively own the government and can do what they want. The telco monopolies are exhibit A.
Yes, that's true. That can help with international rate discrepancies for ecommerce sites that have those different TLD's. But I know for a fact that there are large ecommerce sites out there that are not doing per-TLD ad syndication, as they probably should.

Also, shipping rates within a single country can still vary pretty dramatically based on distance traveled, whether you're shipping to a remote area postal code, etc.
Strongly agree with this. A lot of founders make the mistake of prematurely scaling, and I've done that in the past.

Scaling from a handful of people, to more than a dozen creates a significant jump in stress, and dilutes focus, for a non-commensurate jump in productivity. Any pre-PMF startup should be as small as humanly possible.
I think the issue was bureaucracy slowing down the ability to adapt, and using contracts as one example of dramatic buraucracy.

An anecdote is that Krikzz was a Ukraine company. He moved to Spain when war begin and is slowly starting to ship stuff again.

I think we are too many to go entirely extinct. Our ancestors survived an ice age, after all. We may go back to the stone age or at least middle age level of tech, but the species itself will survive. As long as the surface of earth is somewhat survivable, humanity will keep on going somehow.

What i actually think might happen is some form of evolution. Probably combined with technology. Genetic and bionic modifications will become normal and at some point in the far future, there won't be a homo sapiens anymore. Idk how to call it. Homo Machina or something? That might even get rid of certain limits of our bodies, so that a sudden extinction will be more unlikely. Can't kill what can live on almost any (solid) celestial body.
It is annoying to see idiots get a lot of attention, but really, it is not a glorification of a stupid act, it is just a video of one. Furthermore, it would live on in all of those videos that point out just how stupid it was, unless Youtube also removes those - but they are informative, I would say.
Not neccesarily? If you start with an Android app, the sentiment tends to go both ways. There's simply no good cross-platform mobile toolkits.

But what was the attack and the change?
This is the big reveal of the Keanu Reeves/Thomas Middleditch (no, that's really the cast) movie "Replicas". I am deliberately spoiling it to save anyone else the pain of watching it.

My best-case scenario is that the movie does not exist, and my memories of watching it are simply my brain's dying hallucinations, patching together memories of The Matrix, Johnny Mnemonic When I Was 13, and Silicon Valley Seasons 1-3.
But this also cuts both ways - really nice if it works but you will also look pretty stupid if you accidentally brick an entire satellite constellation or some malicious actor uses this capability against you. But I obviously have absolutely no clue what they are actually doing, so I will abstain from any judgement.

if Apple allowed an iMessage compatible app to be developed on android, r even sold it themselves, I would buy it for this reason.

TBH such response does not require CD, only a proper support process where critical fixes can be delivered within hours or minutes.

CD is for delivering everything this way, which is not always necessary from business perspective.
I don’t know about apps, but websites are marketing and in marketing you need to stand out. Hence the ever changing trends in design.
I only write by hand, when I need to quickly note down something for myself. For that purpose cursive is by *orders of magnitude* better than "typesetting by hand".
About half of the trees in a New England forest are "invasive." They've been here so long someone like me doesn't even know what's natural and what isn't.

Earthworms are also invasive in New England. They're everywhere, ubiquitous, and apparently the natural forest doesn't have them.

Ask HN: How are pull requests integrated in a repo with high commit frequency?
So let's assume we open a pull request, merged current main into our feature branch and are running tests. The full acceptance test suite takes 5 minutes to complete.
Meanwhile, in those 5 minutes, 10 other commits have been made. If we merge now, we can't be sure that we won't break stuff right?

So after merging the pull request, are you supposed to perform another set of regression tests? Hard to find info about that
Good article with some interesting conceptual theory and visual examples!

I'm a Gumroad user and I do like their admin panel because it follows this kind of style. I'd personally call it "pop-art inspired" rather than giving it a label however. I'm sure I saw a similarly detailed article from another site talking about "glassmorphism", and that never really took off.

There's a page builder that's built with this kind of neo-Geocities aesthetic that's pretty fun:

We used to fund distributed disruptive technologies to subvert Soviet censorship. Chinese censorship was seen as proof of our superior freedom 20 years ago. Now it is viewed with envy by those in power. What moral high ground do we hold now?
for the record, i absolutely loath needing 3+ subscriptions to streaming content providers AND a delivery bill (internets) just to enjoy what comes out to 5 or 6 "shows/movies" a month. No, I do not have a reasonable solution, just griping
I've read (need to dig up the source again) that high infrastructure costs in the US are in part due to the same problem. The government doesn't even have experts anymore who could write the request to take offers on. Maybe in some cases a slightly larger government can be a leaner government.
It can, but there are a lot of people studying causes of homosexuality nevertheless.

And even if there weren't, if the back-of-the-envelope evidence points in the opposite direction (if there's any correlation at all between homosexuality and fungi in foods, it's that we're observing more people declare themselves to be homosexual in populations eating commercially produced and processed food screened for zearalenone which is the opposite of the expected result if zearalenone is the causal factor, and "outbreaks" of homosexuality amongst groups with shared diets simply aren't observed) it's not a theory with much in its favour.
Does this not result in potentially having to resolve a conflict several times? If you have 3 commits working in a block of code and then you rebase over master that has one commit changing the same area, do you not end up resolving the conflict for each of your commits?
I'm responding to the comment.
I agree that it is relatively rare for sort to be your bottleneck. What I meant is that in that relatively rare circumstance most people are going to look outside the standard library and try a few different sorts.

My comment also had a more dismissive tone than I intended.
IMO, a good start would be to fix the OOMKiller to kill all processes that overcommit first ordered by size of overcommit (maybe match the uid first).
I've used custom made implementation in Java ( proprietary based on the owner thesis ) to optimize train crossings for big mining companies like Vale, BHP and Rio tinto, it was stressful but super fun work!

Lot's of money to be made on it too if you guys are interested, but it's super niche and hard to get into. There is a huge resistence from train controllers and other workers. I actually understand it because of the job loss involved but it was super cool being in a NASA like control center sorrounded by panels and monitors and seeing the trains moving based on code I and other wrote!

It was a just in time local optimization with lots of heuristics and business rules embedded into it. Basically impossible to reuse between companies or even railroads sometimes, the controller would then solve all the more complex crossing that involved either some lose-lose choice or a pre-defined business decision.

The train controllers are amazing at their jobs, it's super stressful and a single mistake can kill people or make the whole thing stop for weeks, with the software running it made it a lot less risky, one dude could control an area that needed 7 or more people without it, with minor interventions.

> In penmanship class, we learned a standard cursive font. I think it’s the standard cursive font, in fact.

He's wrong that there's a standard cursive. Different countries and different centuries have used a variety of different cursives. Most Americans who were taught cursive in school learned either Zaner-Bloser or D'Nealian, which both derive from Palmer. Both of them are terrible. They have indistinct letter shapes that degrade horribly when written quickly.

Cursive Italic handwriting is much more legible, if slightly slower. There are popular systems including Getty-Dubay Italic and Barchowsky Fluent Handwriting. Both of those are fine, and should be strongly preferred to 19th-20th century cursive.

I had a huge struggle debugging an issue on HoloLens that turned out to just be mis-calibrated IPD.

Unbeknownst to myself, a coworker had ran the calibration on himself the night before and when I got the device back, suddenly all my graphics of 3D models overlapping real-world objects looked "wrong". Every time I tried to visually adjust the registration of the model to the object, it would be completely unaligned in the z-axis with respect to my view when I performed the alignment. Midway through debugging, I tried adjusting from multiple angles to get the model absolutely centered on the object, which then made it look like it was swimming in the air whenever I walked around it.

I started to think there was something wrong with the device tracking, so I went through every calibration process on the device. I left IPD for last because I was used to working in VR where it doesn't really matter all that much, so I didn't expect it to be that important. IPD calibration on the original HoloLens was also a gigantic pain in the ass, as it took well over a full minute if clicking on objects with that interminable "air tap". Suddenly everything locked into place and was rock solid.

Immediately bought IPD measuring tools, had my own measurements confirmed by my optometrist, and it's now the first thing I check on every new headset. Every auto calibration system I've used regularly gets my IPD be wrong by +-5mm. I don't know if that's a significant difference (it's almost 10%, so seems like it), but I don't take any chances anymore.
This is one of the most minor concern I can imagine for a startup.

>I am all in favor of sharing ownership with those who shared the risk and the burden, but the governing laws weren’t written weren’t written for this, so it needs to be taken account in the specific agreements.

These issues almost never happen and the process for giving employees equity interest is well developed. The standard SPAs always have ROFO clauses and such. There's no need to innovate -- any Vally law firm's standard docs have everything needed.

In the US shareholders of private companies have pretty limited inspection rights: basically public filings and board minutes etc (usually the latter say things like "the CEO presented the last quarter's performance and a discussion ensued"). Preferred investors negotiate more detailed inspection rights.

In 30+ years of running startups in the Bay Area I have never seen any of the things you describe happen (not just my own companies -- never seen them happen). OTOH, at the second company sold (first one I founded) the front desk receptionist made enough to pay off her mortgage and fully fund her retirement. That's the way things should work.

Spend your energy on the upside.
Oh that makes sense.

And it's an airplane, the ultimate sword of Damocles hanging over people's heads by a horse hair, yeah this was like a fucking kamikaze.

And like the other commenters say, there are means to do aircraft destructions properly, with permission and so forth, meaning in that case with 0% chance of killing living things and therefore no felony.
>What is this talk about “the algorithm,” as in Musk saying “they should open source the algorithm.” Is this the traffic boosting and suppression mechanism?

If for example you make a post that says "Vaccines cause autism". They dont have enough humans to moderate this. They write an algorithm that generally sees that and you get shadowbanned or equivalent.

Disappointing that there's not a word written about which group found their diet easier to stick to. The same calorie intake leading to the same results is a completely unsurprising outcome. What's much more relevant is what makes it easiest for people to stick to such an intake.
Probably much more banal than the article leads us to believe. Russia probably began jamming on <frequency x>, Starlink deployed a change to fail over the terminals to broadcast on <frequency y>. Would be my guess.
it's worth noting that the virtual console (wii, wii u) releases are built off of the original nstc edition, meaning backwards long jumping is in play. but the most recent 3d all stars edition is based off of shindou, meaning blj's are not possible.

I live a little south of Boston. In the spring I often get large rafters (herds) of turkeys on my lawn. Sometimes there are 30 or more going through my neighborhood.

My 1-year-old loves staring at the window and pointing at the toms (males) with their giant plumes. They look like peacocks when they spread their tail feathers out to attract a hen. I have to sit my daughter at the window while we eat breakfast because she just has to stare at them.

Apparently turkeys prefer to mate in fields, so they like doing their thing on lawns. Good to know that at least something wile benefits from mine.

It looks like you have different problems here:

1. Credible sources.
2. Tools and methods for searching and matching.

In my opinion:

1. It's very subjective. Pepople just believe in different things. It's hard and time consuming. There is no the single point of truth.
2. For this purpose I wrote https://github.com/livelace/gosquito and I extract different keywords (tech, people, orgs etc.) from information flows. It frees my time heavily.

Hey, thanks for the (implied?) question.

We are a lot more concerned with making customers feel like part of the company’s growth than worrying about competitors.

Our customers love seeing the roadmap. And we are lucky to have an engineering team that really does deliver what’s promised. So we like to show that (hence the public release notes that connect to items on the roadmap).

This gives customers confidence that we really will deliver what we say we will, and they can plan their adoption of the product around it.

The community also really loves seeing their own suggestions make it into the roadmap. The way I see it, we’re all building this together.

At the end of the day, it’s not the best product that will always win. It comes down to community.
Seems like you could install the kext to the internal drive, then use a tool like Carbon Copy Cloner to build a bootable external copy of the internal system with the kext installed.
I just don't get why anyone would want their city to run an internet service? It seems like the most of awful thing that I could ever be forced to endure.

I'll give you a few easy examples: I moved from one house to another, the city owned electric company demanded a $200 deposit. Literally in the same area, same city owned electric. According to them I had a "history of non-payment". I asked about my original deposit, the employee told me I got it back. I asked when, he told me he could not tell me. I asked to speak to his supervisor, who also told me he could not tell me. He then proceeded to tell me to shut up about it. So far, I've payed $400 in deposits that I'll never see again.

The same city utility routinely sent me water bills that made no sense. I would get bills for <500 gallons of usage per month. Then suddenly a bill for 10x the usage amount, but all billed for water. Somehow I didn't use any sewer. Had a plumber confirm no leaks in the system. Later I would find out the meter readers simply falsify the readings in that area.

Somehow when I moved, they put trash service on my account. I'm not even in their service area for trash.

But the real icing is COVID! For years the city has operated a bulk trash collection at the curb and hazardous waste collection at a facility. When COVID started, they just suspended it. For health concerns. 2 years later they are still collecting fees while city council is holding meetings about the increase in illegal dumping of trash in the area.

This is the same group that is going to provide me internet service? Pass.
