This explanation is a bit hand-wavy, but "correct enough" for our purposes.

Let us suppose that you wanted to store some per-thread data.

A naive way to do that could be to have a global mapping from thread ID to a pointer to your data. To look up your data, you would obtain the id of your current thread and look it up in the map. Of course, since that map is shared across threads, you'd also need to protect it with a mutex.

Operating systems themselves need to maintain per-thread data. When context-switching between threads, the OS will also switch out the current block of per-thread data. Applications can piggyback on this, so instead of needing to lock a shared map and then do a lookup to retrieve their data, it will already be available to them by virtue of the fact that it is essentially part of the current thread's context. No locking or global map lookups necessary!
Not really following the intention here. The Dynamo paper is still worth reading now. There are other research results and applications of them all the time. Most of these take an annoyingly long time to gain adoption so there's not really that much of a rush unless you're actually in the field of creating rather than assessing and using.

Why does it have to be "as they happen?" I'm happy to learn about anything interesting regardless of how old it is. Sometimes an old idea in a new context can have new applications.
I've been called out in a group dinner invite for having a green bubble, but they may have been joking. I'm really curious where the concept originates; my guess is some supremely subtle submarine social influencer targeting by Apple marketing.

AFAIK, they still have but, it might not be sufficiently advanced to produce R5's sensor. I'm not sure about the origin of R5's sensor as I said.

This paragraph contains neither "UN's actual position" nor a disclaimer, so I don't why you keep posting it.

If you actually understand how the UN works, clarify for the rest of us, who would be the UN authority on the matter. I would humbly accept the enlightenment.

Alternatively, if you don't know, you should not be running around and accusing people of "false or malicious ways" and "spin". You seem to be misinterpreting the statement .

Not everything UN does needs to be a resolution passed passed by 194 countries in the general assembly.
This is why I love this forum!

Would you happen to know any details on the OS/processor of the old sony PRS-350 e-readers?
This is not a good use case for the Mercator projection.

Mercator sacrifices area accuracy to facilitate navigation.

On the opposite note, Russia (USSR) was "invaded" (sort of, from the point of view of many Russians) by the "West" 30 years ago, and USSR was butchered out, despite USSR having thousands of warheads. Which were completely useless...
I think you're being needlessly pedantic. Just because it's easy to derive doesn't mean it's immediately obvious. I only realized it when I watched a 3Brown1Blue video where he pointed it out as interesting property of the unit circle. That alone tells me its not that obvious to many.
Have you seen videos of the Sony a9 Ii? It can autofocus moving subjects and take a picture in a twentieth of a second (!)

So no, I don't think DSLRs have better autofocus than mirrorless cameras. Mirrorless cameras can also do things like eye AF, video tracking AF, and so on.
No idea what the flagged comment said, but presumably she would have set up her own email server and deleted her Facebook account.

:-)
That's fair. Maybe it's worth looking into again.

> You are running this sequentially and by hand?! What happens when the server is dead and you need a new one? You provision it by hand and go through the stages to get it into the state where it can accept the same cattle command?

Depends on the change, but generally something like that. Change + Verify. It really doesn't take much more than 10-15 minutes for any given change. We've been at a stable state for about 2 years so changes are rare at this point, other than our security update cycle.

For rebuilds, we pull periodic disk images (monthly + any major changes) and can stand up a new server in about 20 minutes, almost all of which is hands-off.

JSON is valid YAML, so that should "just work" already. Have you tried it?

Ask HN: Could downvoting work better if a reason had to be entered?
The ability to provide meaningful and respectful feedback is as important as someone who may provoke or try to stir trouble.

I'm curious if YC has toyed with the idea of increasing the right to downvote to have to include a comment, explanation, or reasoning that is not a few characters.
I'm trying to figure out what you're suggesting here. That we should ban advertising? That untargeted advertising is somehow socially better than targeted advertising?

Practically every commercial interaction (and most social interactions) are "manipulation" of some sort. At the moment we're trying to manipulate each other into adopting the other person's perspective. I don't understand what you find insidious about sales pitches; I'm sure they've been with us almost as long as prostitution.

I don't know that we even need to reach the question of whether the NYT, WaPo, and CNN uniformly marketed the Iraq war to dispose of this argument. Consider: the NYT, WaPo, and CNN are unanimously pushing the same narrative about combating the pandemic, and, with one very notable exception, that narrative is the same as the public health establishment. The pandemic will kill far more Americans than the Iraq war did; it's a generation-defining story. Is the press "un-free" because they're warmly reporting on lockdown, social distancing, and mask-wearing measures by the government? Or can the press sometimes simply agree organically about things?

If the press needs to function like a series of warring contrarian subreddits to validate itself for you, we're operating from incompatible premises.
I am as cynical about the behavior of large corporations as anyone. But you can never really know anybody's motivations, only guess them from their actions.

Verizon could be doing it because of ad budgeting reasons. Verizon could be doing it because of public pressure. Most likely, both benefits go into their cost-benefit analysis.

>Test-driven development was supposed to eliminate the need for independent testing.

Citation needed.

On the contrary, it frees up QA humans from writing "test for code bugs" and gives them more time to evaluate "but does it do what customers want?"
If you want a low-end Sony lens you have the option of third party glass. If you want a high end lens you can go with the GM line up that is generally even better than Canon L.

Also, you can just adapt lenses from Canon to Sony.
As a mobile developer I read this eagerly looking for any useful ideas to bring UI testing into my client projects. I’m digesting still but so far, no.

I’m intrigued by screenshot testing but can it work across all screen sizes, from iPhone 6 to XR to iPad, and work in all orientations?

Otherwise my problems are that our designer made tap pinned too small in a couple places without anyone noticing. Or that something isn’t perfectly aligned or a line separator isn’t long enough, etc. they always seem to require a human to use it and say, I don’t like this or this could be better.
The triggering event, as I understand it, is they did not censor the President of the United States who said something to the effect of riots lead to death. There's two ways to interpret this. One way is that eventually people will get hurt in some way if riots continue. Another way to interpret it was as a death threat to protesters. FB's position was that even if it was a threat, that the protesters needed to know that the President was going to send in the military to come kill them. So they did not censor or otherwise flag the post. This is perceived as FB promoting violence.
This has been my camera since 2017 https://www.amazon.com/gp/product/B016LMB770/ref=ppx_yo_dt_b...

And I got this cool lens-cap for it https://www.amazon.com/gp/product/B00I1CP2MU/ref=ppx_yo_dt_b... that has an automatic opening when you turn the camera on, great for traveling.

Before that I had the E-P2 https://www.amazon.com/Olympus-Interchangeable-Digital-Elect...

I'm still using the telephoto lens that I got from the E-P2, it wasn't very expensive, I think it's this one https://www.amazon.com/Olympus-40-150mm-F4-0-5-6-Panasonic-C...
In terms of new units sold as far as high end cameras, I'm fairly sure Sony has passed Nikon since a good while.
You seem to assume that working on weapons programs for the military is wrong, and I'm not sure why. Defense (and war) are one of the core reasons for the existence of the US government, and are clearly enumerated in the constitution.

Do you think the armed forces should be disbanded? If not, should the armed forces achieve their objectives through the use of obsolete equipment, or would you prefer they simply import it?
I edited my post, and hopefully it reads more clearly now.
“Time is money” is a cliche, not a fact. There are plenty of people who have lots of money but didn’t spend commensurate time getting it, as there are plenty of people who spend inordinate amounts of time making little money.
One word, and I'm not even religious: Amen!

A few more words: this new-found fixation on skin colour (and gender, sexual orientation, gender expression and all those other identities picked up or made up by those who practice intersectionality) really needs to be dropped right now or we - as in what used to be called 'the west' - risk falling back to the way things were in the 60's or earlier, depending on which country you're talking about.

It goes without saying - but needs to be said in the current climate where trigger-happy index fingers try to outdo each other in pointing out -ists and -phobes - that bad policies need to be rejected, bad implementations of good policies need to be corrected, where illegal discrimination is found it needs to be undone and all that jazz. For the rest we - and that means all sides which have been set up against each other - need to drop our verbal tomahawks, look those people on the other side of the barricades in their eyes and tell them we should try to agree on disagreeing on some points but that we mostly share a common goal and should do our best to reach it without getting it each others way too much while getting there. We can take different paths, some of us may be quicker to get there than others and it is up to us all to make sure those who really can't make it on their own are given a helping hand but one thing should be clear from the get-go: if our first step is to identify everyone who is not in our specific and ever-narrowing in-group as enemies the only thing we'll be good at is creating more discontent and chaos.
I have like all the primes. My favorites are the 45 and the 75mm, since I mostly do portraiture. Those are both tack-sharp edge to edge, every aperture. I have the EM-5 mk II body. I was just about to upgrade to the mk III... but I'm not sure if now it's a better or worse time to do it. Maybe I should while there's still stock, since I think this is going to be my system for the rest of time.

Modifying other people's code is kind of like a severe type of copyediting.
Thank you! This was definitely something that I never thought about. Currently, my work does not have any type of "feedback" loop cause none of it is consumer facing.
I am under the impression that they expect a real name. In fact, they give a section to allow further proof in case you are someone famous, so that someone isn't trying to impersonate you:

"Let us know it's actually you? (Optional)
For high-profile signees (CEOs, authors, people with 100k+ twitter followers, etc), we'd like to make sure nobody is impersonating you. Feel free to give us an official email address to confirm (we will not use it for any purpose beyond validation and will not share it with anyone), or link to a public post/tweet where you say you signed this petition."

> only do what maximizes their own financials

So if a company feels like they can acquire more customers or employees, or gain positive publicity by taking certain actions and expressing their right to free speech, shouldn't they be able to? This is why businesses take political stances in the first place. A company would be doing a disservice to shareholders by _not_ taking an action which could improve financials.

Before gay marriage was legal, for example, companies would stand up for gay rights and offer gay employees equal benefits, because it would help with talent acquisition and expand their pool of possible employees. This is a "political" stance with clear selfish, financial implications.

You have the right to not shop or procure services at a business which does not support your ideology, but others have their own right to choose companies based on the actions they take. That's the beauty of the free market.

Regulating or otherwise stifling companies' speech and actions in this way simply hinders progress and the marketplace of ideas.
I support your position of outlawing lobbyists, overturning Citizens United and instituting a blanket ban on political contributions by corporations.
While I do believe the Facebook boycott is real, Verizon has a fairly large advertising/media business of their own and so is competitor to Facebook. Not mentioning this as part of reporting isn't great journalism.
If I'm following, the DNS query to your VPN providers recursive resolver is getting a 10.x.x.x IP address. So the Amazon authoritative DNS server must be generating different responses based on which DNS resolver you use.

From a purely technical perspective, I'd think DNS over HTTPS (DoH) would let you bypass the VPN providers DNS server and use 1.1.1.1 or something.

How many VPN providers are affected? Which VPN provider were you using?
Url editing on iphone safari is highly messed up experience ... the text selection and editing behavior is just broken since ios 12 or 11 -- whichever one introduced the new text selection model ...

My standard easy repro -- go to a long url and try to edit the second to last segment of the url path (something which i do for work frequently when folks send me links to projects under development).

Enjoy the frustration.
while ansible does push more commonly (and checkout mitogen for speed increases there), its also trivial to do pull mode with some loss of multi-node orchestration, and just cron/systemd timer it.
No offence but I’m guessing you haven’t taken many photos with an iPhone 11 Pro.
Many of the comments in this thread do not understand the concept of free speech from a legal perspective.

Free speech does not mean that you have the right to say or distribute whatever you want on whatever platform, owned by a private corporation you want.

on a side note - these are super dog whistle comments, and I'm surprised the mods are ok with them.
I really don't understand this protest at all. If they really care about this, why aren't they pulling from YouTube and Google? Which has very very bad comment sections? I'm not for big corporations calling for people to police speech. Patagonia boycotted Facebook, but they have 13 factories in China...a country with concentration camps for Muslims and political prisoners. A lot of corporate good will falls on deaf ears for me, especially when they have been so silent on issues in China/Hong Kong/Taiwan. Money talks, if this weren't a profitable thing to do, they wouldn't do it.
Has there ever been a case where this occurred (with a market clearing mining fee is included)? You only need one miner to include the transaction.
An IP address is often less specific than a hostname, and will become less useful over time due to IPv4 address space exhaustion and concentration of internet services among a small number of cloud providers. Widespread use of DOH therefore makes it harder for ISPs and middleboxes to interfere without collateral damage. It's far from perfect, but it'll help.
"Let's encrypt DNS queries but send them to the ISP which can associate the query with subscriber info!"
Off the top of my head

1) simple transactions--commit all or none of statements from 'begin/start transaction' and 'commit/rollback'

2) like (1) but with support for nesting

3) like (2) but simulated with snapshot restore points

4) everything is saved all the time but you mark which saved things are complete and actionable/visible, e.g. sagas.

maybe others?

Edit: stored procedures can also be useful as they can easily be retried

Spot on. To quote Marshall Rosenberg quoting Hannah Arendt:

In her book Eichmann in Jerusalem, which documents the war crimes trial of Nazi officer Adolf Eichmann, Hannah Arendt quotes Eichmann saying that he and his fellow officers had their own name for the responsibility-denying language they used. They called it Amtssprache, loosely translated into English as “office talk” or “bureaucratese.” For example, if asked why they took a certain action, the response would be, “I had to.” If asked why they “had to,” the answer would be, “Superiors’ orders.” “Company policy.” “It was the law.”

From Nonviolent Communication, page 19 on “Denial of Responsibility”.

Sad to see there's a lot of office talk being used in this thread.
Lots of my friends are switching over to Sony. Sony high end gear works better out of the box. My Nikon fluorite 600mm f4 E and D850 has to be recalibrated for wide temperature changes. I expect my DSLR and lens to know when its in focus, not for me to have to tell it periodically where best focus is.
just re: your last statement, it could make sense if parking costs are high enough. but otherwise, good points
The thing about arm that's always troubled me, which I only see talked about infrequently, is the way it's licensed vs x86_64 chips. Arm chips are licensed in such a way that allows for a multitude of different proprietary configurations that all are essentially arm chips, but locked down at the whims of the manufacturers.

I understand power usage is a big concern these days, but I can't help but feel this aspect of arm is greatly overlooked and that the push towards arm devices is also partially inspired by the ability to lock down chip designs to a greater capacity than x86_64 chips.

Just look at the existing fragmentation among arm powered devices as is. I don't really like the thought of what an arm powered future could look like.

I really wish I could remember what video it was, but I remember years ago watching the ceo of arm present a new chip with built in emulation technology, that theoretically, would have allowed multiple operating systems to run at once or something. I remember the person talking to him asked if he forsaw this as the future, and he just laughed and said oh no, no manufacturers would never dream of allowing this and furthermore they'll likely use this technology to further specialize and lockdown their chips.

It may be personal bias, but since then and other things i've learned about arm, I've just had this lingering unease as to what them gaining dominance would mean to general computing.
It seems to be such short-term thinking to me. They became a desirable brand because creatives both used and recommended them.
That happens basically every election. We've been slipping in free speech freedoms in various indexes for 20 years now, and that has been regardless of who is in office.
The first desktop to use the ARM architecture was the BBC micro, it was used as the second processor when it was being developed.

The Archimedes was the first ARM desktop computer.

An important distinction I feel.

Despite the Maduro Regime launching Petro (State-based crytocurrency) they do not accept it for their official documents, nor do they accept Credit Cards, they do however seem to accept BTC. Which makes sense because for a time the Government thugs were raiding Bitcoin miners and taking their rigs and funds.

Alexandra is a total badass, I like her defiant attitude towards Academia as a whole, and will be supporting her efforts once again this year. Free access to Scientific Journals is fundamental for a well Educated populace and should be available to all who seek the knowledge.

What's even crazier is that COVID has shown us that in dire situations, the walled-garden Peer Reviewed system isn't always best:

https://www.wired.com/story/peer-reviewed-scientific-journal...

I've seen how petty the peer reviewed system is in the 'publish or die' model in the Health Sciences, its petty and pathetic to see grown men and women alike having to resort to such unscrupulous antics to keep up with the illusion that this is what serves as one of the notable metrics for tenure.

As much as I like SciHub, I hope that her success is measured not by the amount of domains and servers she was able to maintain, but by her/SciHub no longer being needed as the paradigm finally shifted.
Same way we can have an open discussion on this lovely site we call HN.

While I'm not going to claim to know every definition of advertising, generally if money changes hands for priority over organic traffic that fits the bill pretty well for me. Doubly so if you're able to target specific categories and demographics. I think what makes microtargeting so bad in particular is that you can do things that would be negative to the broader public but narrow the scope so you have multiple sides of a campaign that doesn't let the public have a reasonable view of that campaign/issue as a whole.
