Where did I say the Chinese government was going to bail out Evergrande? The people making purchases from live streamers are going to bail out Evergrande!

Anyway, I find it curious that my sarcastic comment resulted in such a long rant.
I am always amazed when otherwise intelligent people assert without data that the marginal cost of serving web traffic to scrapers/bots is zero. It is kind of like people who say "Why don't they put more fuel in the rocket so it can get all the way into orbit with just one stage?"

It sounds great but it is a completely ignorant thing to say.

> A simple way to fix this would be to shift c by 24u, "(c << 24u)" which would promote both values to unsigned int

This works for most arithmetic operators, but not shift: "The type of the result is that of the promoted left operand". The type of the right-hand-side has no effect on the type of the result.

To fix this, you'd need to cast the left-hand-side to a type that is wide enough.

Companies who want to keep staff need to proactively work this out rather than wait for employees to make demands, or you end up only with employees prepared to make demands. Not everyone is emotionally or culturally comfortable with that. It is a management problem. Thankfully many companies are tackling the issue because diversity, as one of the numerous reasons there are things like gender pay gaps is that people in many less privileged social groups are uncomfortable or unwilling to make demands of their employer.
> Show HN: Use your iPhone's camera to see any photo on your wall

The wording of this headline is not good. The concept he means to convey is that you can use AR to project any photo you have in your library, onto your wall using your iPhone + camera, and see it in a virtual picture frame.

The headline makes it sound like somehow your iPhone has magical access to see the photos on your wall in your house.

> There is no reason to think that a few idioms and curating features could go a long way to leading to a much better, less hacky paradigm for bash shell scripting.

A couple of years ago, I challenged myself to write some complex scripts and apps using only Bash, and came to this conclusion myself.

You can get pretty far with just Bash alone, especially if you strive to write readable and maintainable code, and not just one off scripts. If you need access to data structures, especially nested ones, you can shell out to another language and then print the results back to stdout so Bash can use them:

$ get_data | transform_data | python3 ./complex_script.py | consume_results
I don't like the name. I think it is awkward, and that "-ify"'ing everything will soon be an anachronism, like trend of the 2010's with restaurants and stores named "Noun & Noun".

That being said, it is a really clever application! I can't believe with all the big brains working on AR that no one came up with this until now. Nice!

EDIT: Not to say the author's brain isn't big, just saying that now that I've seen it, it seems obvious that it should exist, which is the mark of good technology.

Reminds me a bit of the old Ribbonfarm post "CEOs Don't Steer"

https://www.ribbonfarm.com/2017/11/09/ceos-dont-steer/

He basically makes the argument that companies live or die by their focus on a long term strategy, and the role of the CEO is to basically be the human embodiment of that strategy. The CEO repeats themself over and over and over again so that everyone at the company intuitively knows what they want and what direction to move it.
What are the causes? The article doesn’t explain.
Isn't it just the first choice in the list? IntelliJ offers several vendors (Amazon, Azul, Bellsoft, Eclipse, IBM, Oracle, SAP), defaulting to Oracle JDK 17. But I assume you need an older version for Android development.
And there will be even more churn due to two factors:

1. Vax mandates. I thought the admin would have enough sense to impose these after Christmas (or not impose them at all), but they're dumb enough to fuck up the economy right as we go into the holidays. I predict much regret in the midterms.

2. Inflation - unskilled workers might not be able to afford food/shelter anymore at their current level of income, and will therefore be forced to find better paying jobs. Upper middle class me is starting to feel the sticker shock at the grocery store ($350 at Costco the other day), I can only imagine how it is for folks of lesser means. Worse, this will be ongoing as inflation always outpaces income growth at the lower end of the labor market, and "better paying jobs" will cause even more inflation as costs will be passed onto the consumers.
“Only would have needed one”.
I don't completely disagree (although I feel like there have been a lot of naive and overly simplistic CD "thoughts" posted on HN recently that rubbed me the wrong way). But consider on one hand the "fake news" / misinformation problem or whatever people want to call it, and the legacy academic publishing industry on the other. I'm looking at this from the perspective of an academic, the target audience of the publications, not a layperson for whom they are not designed. Like it or not, big concentrated power in academic publishing largely addresses trust in the quality of the publications. Good faculty want to review or serve as editor for good publications, and researchers will follow and rely on the quality of reputable, high impact factor publications. I know it's not always as simple as that, but I liked opening a new issue of my go-to journal and knowing that what I was reading had gone through a good review and was curated to be stuff that was relevant to me. I'm glad my university paid for it.

Not saying there are not other ways, but that these "scams" are providing a valuable service.

(And I'm aware of examples of bad research, retracted papers, etc, these are mostly issues for laypeople and the media, they have almost no impact on researchers and occur with insignificant frequency)

(And there are lots of real scams and rent seeking in the industry, but not what is covered in the twitter posts)
I think you know very little of manufacturing.

I worked in the industry for 10 years.

The two best mechanical engineers I knew weren't engineers as such, as they had no university education.

>> That's why the boats you see full of migrants are typically 100% male.

That's even better honestly. They don't bring families, they will work more, and will not take maternity leaves.

>> Villages will band together to finance people smugglers to take a few of their young men to Europe.

Why actually not to make it more civilised, and put a visa on deposit.

The deposit goes towards initial accomodations, and most basic courses/boot camp.

If everything goes well, the guy can draw it once his taxes exceed that amount n-fold.

> The migrants are rarely literate in their own languages, let alone Italian/German.

That's because most of Africa speaks either French, or English. You see very little Bantu speakers in Europe.
Why do you say it's exactly the same code ? Any Java developers can remember once in his life when openJDK didn't behave as the Oracle one, so you have to test. It's not the same binary, you remember times it behaved differently, and the client is important = you test once that it starts up at least, no ?

This article[1] from Brookings says,

>> At the time of the divestiture, the oil industry was becoming competitive because it was moving into Kansas, Oklahoma, Texas, Louisiana and California—states where Standard Oil didn’t have much power. The price of petroleum was actually falling in the years before the case, because these new fields were pumping so much crude. The breakup had no measurable effect on oil production, crude-oil prices or refined-product prices.

(The article does say that antitrust actions were necessary to make cigarettes affordable, though.)

For a rather less charitable take, [2] from the "Competitive Enterprise Institute" says,

>> Standard Oil Co. of New Jersey v. United States had a defendant that was cutting prices while increasing output. The case also lacked evidence of either predatory pricing or consumer harm.

After this quick bullet-point summary, there's more content below with references to other academic sources, page 2 is pretty interesting.

> many would consider social media companies to be natural monopolies in the current context

They have positive returns to scale, but even this phrasing ("social media companies") deflates the argument -- Facebook competes with Twitter competes with TikTok competes with Reddit competes with Youtube etc. They're big enough to exert market power, but

- Some of them seem to dislike using that power (to the horror of authoritarians in many governments who want to co-opt it), and

- If they abuse that power to the detriment of users (raising prices too high, banning enough communities) users will go elsewhere.

2 of my social media accounts have fallen victim to bot detection, despite not using scripts. There are other websites for which I have used scripts, and sometimes ran into CAPTCHA restrictions, but was able to adjust the rate to stay within limits.

CouchSurfing blocked me after I manually searched for the number of active hosts in each country (191 searches), and posted the results on Facebook. Basically I questioned their claim that they have 15 million users - although that may be their total number of registered accounts, the real number of users is about 350k. They didn't like that I said that (on Facebook) so they banned my CouchSurfing account. They refused to give a reason, but it was a month after gathering the data, so I know that it was retaliation for publication.

LinkedIn blocked me 10 days ago, and I'm still trying to appeal to get my account back.

A colleague was leaving, and his manager asked me to ask people around the company to sign his leaving card. Rather than go to 197 people directly, I intentionally wanted to target those who could also help with the software language translation project (my actual work). So I read the list of names, cut it down to 70 "international" people, and started searching for their names on Google. Then I clicked on the first result, usually LinkedIn or Facebook.

The data was useful, and I was able to find willing volunteers for Malay, Russian, and Brazilian Portuguese!

After finding the languages from 55 colleagues over 2 hours, LinkedIn asked for an identity verification: upload a photo of my passport. No problem, I uploaded it. I also sent them a full explanation of what I was doing, why, how it was useful, and a proof of my Google search history.

But rather than reactivate my account, LinkedIn have permanently banned me, and will not explain why.

"We appreciate the time and effort behind your response to us. However, LinkedIn has reviewed your request to appeal the restriction placed on your account and will be maintaining our original decision. This means that access to the account will remain restricted.

We are not at liberty to share any details around investigations, or interpret the terms of service for you."

So when the CAPTCHA says "Are you a robot?", I'm really not sure. Like Pinocchio, "I'm a real boy!"
It's an edge case, it only happens _if_ you have either very long running transactions holding xids, or you haven't vacuumed your database enough and it has to do a blocking vacuum to move the xid forward far enough to wrap around.

Most postgres databases wrap around with no issues.

The problem with increasing the size is a pair of xids are needed for every row, so you're doubling that if you go to 64 bits.

“ In 2007 and 2008, hackers believed to be from China attacked U.S. satellites operated by the U.S. Geological Survey and NASA. In the latter case, they gained control of the craft, but stopped short of issuing it commands. The Russian government, meanwhile, has been accused of widespread, malicious signal jamming, including, in 2018, disrupting GPS transmissions during a NATO exercise in Scandinavia and disabling American surveillance drones in Syria.”

Would be so interesting if a nation state ever takes over a future starlink. Definitely cheaper to hack it than rebuild SpaceX.

This is actually really cool article, though it could be a bit better written for sure.

The new Tesla 8 and 16 bit floating number formats in the Dojo system supports this kind of rounding up/down using a PRNG when compressing neural network parameters from higher precision floats (it is specified in the floating point paper).

The random rounding is needed to not have a bias in the neural network weight updates, but this article improves the rounding method to be more accurate (closer to the real rounding than uniform sampling) without reintroducing bias.

Hijacking your comment to say that the fine print in the EIA chart cited by the person you're replying to says they're only accounting for new and utility scale generation. Utility installs dwarf residential, but if you add all non-utility generation it's quite a bit more substantial, and it was 'only' until early to mid 2010's that utility installations outpaced other installs.

According to an industry group, 20GW of solar was installed last year (3.1GW residential), representing 43% of new generation capacity: https://www.seia.org/research-resources/solar-market-insight...

According to EIA, new wind generation in 2020 was a bit over 14GW.

Walking back from 20GW being 43%, that means in 2020 we had 46GW installed overall, so wind was 30%.

By any measure, 73% of new generation being renewable is pretty impressive. Worldwide the number of solar installs looks almost logarithmic.
I spent a few years laser focused on web property arbitrage in my spare time.

This is my general advice:

* The deals at the lower end (a budget of $2500 is in that segment) are often trash. You'll need to spend an insane amount of time vetting those deals. And most will be niche products with either no route to profit or a severe decline.

* The best deals are the really poorly built PHP SAAS applications run by an old tech-oriented person that has zero marketing experience (one of my best flips was an awful codeigniter tool related to pets.. I literally only added Adsense, cleaned up the copy, and slightly improved the loadspeed, then sold it for a 2x profit).

* If it's a prior flip (e.g the current owner is not the original creator), turn around and find something else. Sometimes they are fantastic, but it's usually a terrible idea.

* Flippa is the Amazon <2015 of web property purchases (in terms of product quality). The best deals are usually in forums, Reddit, or even locally if you know a lot of devs.
I've honestly not had much problem at all crawling the web as an indie search engine operator. If you want to get past CloudFlare you can register your bot fingerprint with them.

A small number of sites has blocked my crawler , but that's almost always been my own fault, and happened a few instances when the crawler was misbehaving and actually fetching too aggressively (or repeatedly). In every case just sending an email to the site explaining what happened and humbly asking for a second chance been enough to be allowed back in.

Most website owners don't seem to mind small search engines at all, what they don't want is scrapers that aggressively scrape their entire site 10 times a day, ignoring robots.txt, and being a general nuisance.
I like the concept, with the addition of known mat colors and frame options it would be an excellent sales tool for framing places.
I mean, they essentially operated 9 of every 10 refineries. That was enough for both the NJ and US courts to deem them a monopoly (yes, they used those words).[1]

And since a monopoly is just “certain business practices” that unfairly constrain competition, your definition seems to be a difference without a distinction.

I'm gonna go on a stretch and argue that while it is true reddit/facebook/twitter killed these communities, I would argue it really had to do with the fact that:

A: these communities never evolved with the times or tried to preserve it's relevancy to it's users - in other words don't touch if it ain't broke.

B: Because of how insular the communities were - I think the admin always either assumed it was a small-time gig or that the community will stay together forever and ever

C: These communities relied heavily on too specific fads (think Naruto fan sites or tumblr like quirk) - compared to start with a fad and then expand

Essentially when you look at successful communities say Newgrounds and compare it with Ebaums World, you'll notice that Newgrounds while being slow it has always tried to stay relevant and branching out while Ebaums world just stayed the same never changing or adjusting and today all but a joke compared to it's former self.

I think the fundamental flaw with (unchecked/nai cross-polination though is that while it is highly successful if done right, allowing unfeathered "all speech is free speech" MO that Twitter, reddit and even Facebook prided itself around 2010-2012 we know how poluted it can become with bad actors to the point it's a systemic problem / literally a threat to business model of said social media (for instance I know youtube's algorithm has been blamed for why extremist content garned such quick and effective attention).

Its not just the valuation, its the % of the economy that is now derived from RE transactions - Canada relies more on RE transactions than...pretty much anywhere. Its no longer an exaggeration to say the Canadian economy is primarily a manifestation of domestic monetary policy and Chinese speculation. There is still resource extraction, but that is also under pressure as the world moves away from fossil fuels.

All bubbles end, when this one ends, Canada will be demolished, and every Canadian social institution (healthcare, education, etc) will be gutted. The only way to avoid that fate is to effectively sell the nation to China, which appears to be what may happen. Canada as a Chinese client state...it may happen.

>Legitimate uses of scraping include price comparison

"Legitimate uses" is what the site operator says it is, nothing more nothing less. There are no laws that says you can scrape a site and circumvent their protection against doing so.
