I'd definitely agree there's nuances about hook behavior that a lot of folks aren't familiar with. (Dan Abramov's mammoth post "A Complete Guide to `useEffect`" [0] ought to be required reading for all React devs, and a lot of the info in that post ought to be better integrated into the React docs directly.) That said:

- The "effect behavior runs bottom to top" has always been true about class lifecycle methods like `componentDidMount` / `componentDidUpdate`. So, nothing new there.

- Somewhat similarly, the aspect of new prop references causing some logic to run every time is not completely new, either - it's similar to how attempts to optimize rendering via use of `PureComponent`, `React.memo()`, and `shouldComponentUpdate` can "break" when the parent component passes down new callback or data object references every time.

- The complaint that "there's more stuff to learn" seems superfluous. If there was never anything new to learn, that would mean that the API was completely stagnant and that nothing new could ever be introduced. Yes, the ecosystem is in a somewhat uncomfortable transition state atm given that there's two different APIs that offer equivalent functionality, but "learning more stuff raises the barrier to entry" is not a particularly meaningful argument against hooks.

Am I the only one who is upset that Lenovo T series has dropped external battery ? I am running Ubuntu on a T480 with an extra battery in my bag. I don't think any other laptop has ever given me as much joy. And I almost never run out of juice even though I always code without being plugged into a power source.

Bring back the external battery !!
You might like Ghost Fleet [1] (or [2] for more colorful review). Ghost Fleet is essentially a white paper turned into a Tom Clancy style techno-thriller on what war might look like between China and the United States. Tactics from Ghost Fleet include:

- Infected microchips from Chinese suppliers used to target and destroy the US Pacific fleet.

- Disabling GPS with anti-satellite missiles.

- Cyber attacks to disrupt the DOD communications networks.

Poor Zoom, first they were scapegoated due to the whole industry’s overuse, or faulty use, of the term ‘end-to-end encryption’ (especially if we believe Snowden’s claims in his latest book that portrays corporate cloud computing as a way for American corporations to create and sustain NSA backdoors). Now the team is probably pretty motivated to kick ass and show the world what they’re made of, considering they have Microsoft Teams, Skype Google Meet and other big co’s as competitors (or maybe it’s the opposite, and Zoom is the bigger NSA Trojan horse here).
I used to work for a company where important deadlines and release dates were often cast in concrete. At the birth date of the former CEO (husband of the current CEO) who had tragically died many years before.

So if your "natural" release date was a few weeks after that birthday, it was definitely on that birthday. You only had a chance to escape that if your "natural" release date was months apart from the birthday.

But then again, this company never ever hired anyone without a positive graphological expert's report.

> This should be the crucial and challenging part to maintain.

More than that, some of the system explicitely _don't_ want to be bridged, because retaining users in their silos brings in more money than maintaining a window to the world outside the silo. It's tolerated at best today, but you can be sure that if a bridge ever get traction, the Whatsapps/Facebooks/Wechats will do what they can to block you.

Rather than betting on the bridges in the long term, I believe it's in your interest (as a Matrix user) to host a bridge to Whatsapp, and tell your Whatsapp friends that it kinda works but it's gonna fail at some point, so they better have a second account for the future. Install the account for them even, that removes some of the friction. But ultimately you have to realize that Whatsapp doesn't want to talk to Matrix (the situation is completely different for an open protocol of course, like IRC or XMPP)

Not surprising, otherwise he wouldn't hold the grudge for so long.

I mean, buying a brand-new device and using Ubuntu 19.04 with the 5.0 kernel from a year ago and outdated packages is begging for trouble.

Since linux drivers live mostly in kernel space, for new devices I would imagine a lot of issues would be fixed by running the latest kernel or mainline for even newer hardware.

The PE funds you describe are only a portion of the many PE strategies. Some take over well managed family owned companies where the family wants out; other acquire parts of larger groups that are being sold off because the current owner needs cash to invest somewhere else; in many cases PE funds come in to provide the cash needed for massive international expansion etc etc. The vulture/turnaround funds you describe certainly exist, and give the acquired company some hope of survival (usually, at least initially, with massive cost cutting). The fact that all these are leveraged investments (some less than others) means that a negative turn in the economy can have a massive negative impact in the ability of the company to cover their debt obligation, hence the bankruptcy.
Zoom and other such software allows you to swap the background out during video calls. Don’t know the tech behind it, but I do believe someone posted about it a couple of weeks ago on HN.

>You also don't need to worry about a browser update causing trouble as you control when you update the browser engine.

This concerns me. Under the current google model, as long as you have a play store compatible device, you get chrome webview updates through the play store, even if the device fw is eol.

If an app developer doesn't update their app, then you can have potentially vulnerable version of geckoview lying around. I hope a decoupling/webview-style update mechanism is eventually implemented, although I don't know how feasible that is (i'm an amateur android dev)

That said, I really do like the project. And, I use firefox as my personal browser, both on principle and because it's quality software.
The next obfuscated code competition is sure gonna be interesting.
GeckoView is fairly tightly focused on Java/Kotlin API. While work in the past allowed Gecko to run on iOS [1] this was not maintained.

AFAIK the original purpose was for anti-theft solutions (eg. computrace) to re-install themselves after a wipe. Before this, they would mount the boot drive and rewrite chkdsk.exe (which gets executed each boot) with their program. That way, their tracking software stays on the system even if you wiped the computer.
It is always an interesting argument whether you should kill all the Grizzlies bears or sharks or snakes in places humans are, or live life around them.

He's saying kill them, one life isn't worth a few bears, some people think the risk is worth it.

Although it's not just bears but large mammals like deer that are the real issue. So again kill them off to keep the roads clear for safety.
I actually don't agree. Many debts in the US are effectively non-collectible, because all the property from which they could be collected is exempted. (This is especially true in Texas, where wages can't be garnished for most debts.)

That's not true of Christianity; this along with Judaism are historical religions. They exist not to pass on wisdom or ideas, but because of historical events, which they claim are the interventions of God in human history. In particular, Christianity exists as a result of the Resurrection, which it claims literally and historically happened. And there is significant proof that it really happened: https://www.newadvent.org/cathen/12789a.htm

Surveillance Capitalism is a well established term that means exactly what it sounds like - capitalism based upon surveillance. This is exactly the business model that Facebook and Google operate upon, and exactly what Sidewalk Labs was attempting. They claim to be benevolent saviours but really they're just there to watch everyone and sell the data to advertisers, governments, and Palantir-alikes.
UBI is definitely not cheaper that current social security. "To administer" maybe, but the total cost is probably orders of magnitude more, and doesn't even solve the problem: certain demographics will still need extra.

Here's the author's web page at Stanford.[1] Not much there. He published a very similar paper in 2017.[2] The actual papers are paywalled. So we don't get to see how big a coil, or whatever, is needed to get 10W at 1 meter.

It's straightforward to do that with a split transformer.
Berkeley used to have an electric bus which recharged at bus stops that way. More trouble that it was worth, but it worked. There's an old patent from, I think, GE, for a scheme for long transformers below highway lanes to do the same thing. The practical question is whether this new thing is substantially better.

Parity–time symmetry is a concept from quantum optics. The author, from his papers, used to do optical work. There's been work on this in the magnetic domain, but at very small scales, like nanometers.[3] Doing this on a scale of meters is new.

No idea whether this makes any sense. None of the non-paywalled papers have anything useful to read. Anybody enough into quantum magnetics to make sense of this?

One of the tactics of a PE company is to effectively buy a company by securitizing its future revenues in the form of debt which is called a 'leveraged buy out'.

Basically a fund will invest a small amount and convince a bank to give them the money for the rest of the acquisition, which will then be in the form of debt to the company, using the revenue stream and assets of the company as collateral.

The banks get a nice loan out there and the PE firm gets full ownership with a lot of leveraged help from the bank.

There are possibly a bunch of structural benefits such as tax optimization, ie interest payments are tax-deductible etc..

It's viewed negatively because it's generally a form of financial engineering re-arranging deck chairs, not really value-creating, although it is for investors.

A company with a lot of debt can be more exposed and more likely to fail in a downturn.

See: Leveraged Buy Out.

As long as the intended audience recognizes them, they’re doing their job.

There is also a significant subculture or sneaker collectors who buy them like someone might a rare run of “collectible” action figures, where rareness is all that matters over the value of the item per se. Some crazy-seeming sneaker prices are just companies catering to that market. Of course there’s overlap and symbiosis with the signaling crowd, too.
Forget mortgage interest deductions. Take a look at cash back rewards cards. Cash-using households ultimately end up transferring money to card-using households this way, because merchants don't usually set higher prices for card users to compensate for fees. See https://www.bostonfed.org/publications/public-policy-discuss...

I get an average of 1-2% off of almost everything I buy simply because I can use a cash back rewards card to do it. It's sickening.
This sucks :(
Whether it is factual or not is irrelevant for the public outcry over the next conspiracy theory. I'm not defending it, but we currently have a crisis of science authority. I'm not sure what to do about it though.

I wonder if putting the system before lights at intersections would help to buy, so to say, people. If it would be cheaper and more convenient for them directly. I think the problem with 5g is that it is not entirely clear how better is it. Also there are probably more people driving, then using mobile Internet. Or at least more people that would protest such undertaking.

As long as you had substantive experience and can show it, then yes. If it was a title only, then probably not.
Open-core, or fully open-source with paid offerings (e.g. Zulip -- see tabbott's comment below [0]).

Let the DIYers host their own instances, but offer support and/or on-premise deployments for a fee. It seems to be what Mattermost, Zulip, and others are doing with some success.

Mattermost also includes use of their mobile notification relay servers in their paid offerings, which is compelling, because otherwise you have to build and distribute your own mobile apps.

Which is part and parcel with these companies. They do some consulting, but in general the only thing they're selling is their brand. And everyone involved is incentivized not to be fully transparent about this when giving media interviews.
I rent, I vote. Plenty of people do vote. But, a typical homeowner in LA is more well off and therefore has more free time to wait in line to vote, so that is who is most likely to vote. There are people here who need to work 60-80 hour weeks to survive.

Static analysis is a lot slower but regular clang++ is also significantly slower than g++, like a 4-5 minute build time vs 2:30 on g++.

It might have something to do with a heavy usage of templates in a few files, I don't know.

Clang's autovectorization is better in a few functions I disassembled but otherwise the generated code doesn't benchmark any faster, it's better in some places, worse in others.

I don't think math is political.

A scientific theory could be considered political only if you think Popper's definition is fundamentally flawed. I don't think his definition is wrong though and i have yet to see someone arguing over the basics since the 80s (nowadays its more bayesians vs frequentists).

> I find it really naive to treat science like some kind of objective methodology that can output unbiased data. Its complete fantasy.

No bayesian scientific will treat science like this.

> "Science" is much more of a set of institutions and social regard for those institutions than an objective methodology

Wrong, there is methodology. Scientific consensus is still the best approximation of the reality we have. It might be wrong, but it is wrong for the right reasons.

> We often just want to throw money and scientists at an issue, and get out good "science" but thats like managers hiring 50% more programmers for 50% better/more code, we know the details are what matters.

Pad argument, this is not comparable.

> At the end of the day, "science" in the real world is a lot of professor vying for tenure, caught in publish or perish, funding coming from self-preserving institutions, and a bunch of overworked grad students. Its a lot of companies making a buck, too.

Yes, good point.

> Everything is political! Everything. If you see something like science, religion, art, anything as apolitical, that probably means its just reinforcing prevailing politics.

I see math as apolitical. Tell me how i'm reinforcing capitalism and liberalism. If you can't, this argument is invalid.

> Check out Anarchistic Epistemology if this idea is of any interest.

Ok, now i see, why you're against the scientific method. Popper's falsification have been largely improved by epistemologist thanks or Feyerabend's critics, and he is right about the "consistency" criterion that was dumped in all fields except medecine and social science.
However this epistemologic theory is old and its argument were already based on old discoveries (galileo, newton) or misrepresentation of newer ones (i think a dozen papers were written against his vision of Einstein, and i find his critics on Feynman really undeserved). If you have knowledge of any epistemologic book[0] on this theory updated with new knowledge i'd like to read it.

Any problem where the inputs are ambiguous. Like when YouTube's ContentID takes down your video of you playing your original composition because someone else decided to claim it. Like when your Gmail account is closed because of a "Terms of Service" violation, but they won't tell you which one or show you what you did wrong. Basically most problems people have with Google could be solved by having a human spend 5 seconds looking into the issue and realizing, "Oh yeah, this is an edge case with an answer that's pretty obvious to a human, but not an algorithm."

If there's tax progression, everyone's net income does not go up. That UBI money has to come from somewhere, and it comes from taxes. To fund the UBI, taxes will need to increase.

So at some threshold level of income, flicking the UBI switch doesn't affect your net income. You get a same size of increase to your tax bill as you gain from the UBI benefit.

Below the threshold you get a net increase, above it you get net decrease. Opinions differ on where that threshold would settle at (because with UBI the state could shut down some other benefits that are currently funded with tax money).
That’s fair. I personally don’t mix typing and trackpad usage very much so that advantage is pretty minimal for me.
