Sweeping new study shows 50 years of 'trickle-down economics' was a 'sham'
Look, I'm saying all these papers are weekend Hackaday projects. You can say it's useful, but it's still trivial, anyone can do it, and shouldn't be held up as a massive accomplishment, nor given as much credit as they are.

> This team has thousands of citations from researchers that I think disagree with you. Someone is citing their work.

It's not like non-research research is a novel problem in academia, so I wouldn't point at citation count as a particularly useful metric. It's not just this guy, the incentives in academia are to publish publish publish, which is why paper mills like this happen.
Maybe this can give you some insight. I downvoted your comment simply because it didn't add anything to the discussion and you made an assumption that has several faults in it.

For one, your "mental model" is off because you assume that the first part of "readable bytes" is accurate. Without actually seeing the PDF in question, you don't know if the "readable bytes" are actually corrupted and Preview is fixing them to make them readable. That would mean that Preview is actually correct in its behavior and the source document is what's flawed.

On the tail end of your mental model, then, is another assumption which is that this results in "unreadable bytes" but that's not accurate either. The PDF that results from a save in Preview may be accurate to the PDF specification and is perfectly readable as a PDF in any PDF application/reader. What's no longer readable is the extra content that was originally in the file that may not have been saved correctly, in-spec, or may have been corrupt to begin with.

A big hint as to what's going on here, now that I've had some time to review this, is that the "corruption" happens consistently - the letter "a" is always replaced by the same "corrupted" character, the letter "b" seems to be consistently replaced with the same character, etc. That points, in my opinion, to a lookup that's no longer correct. What side of that lookup is bad is hard to say without seeing the file in question.
I would imagine that to be the future state.

Other RHEL-compatible distros offer it, I believe.

It's a real problem with her, the language stuff; I cringed every time I saw her say "Latinx" during the campaign, which is a term Latinos overwhelmingly reject, and was originally intended to refer to LGBT Latinos. Obama landed some glancing hits on her presentation style in his most recent book, too.
Not really. I just built a 256 element array covering 2 octaves BW. The feed board is seven layers. Arrays are lots of repetitive circuitry. I think the impressive part are getting microwave RFIC for pennies.

Google doesn't (afaik) sell your data directly, but when they sell ads based on categories they've fit you to, that category information can be harvested.

If it's a ad unit which includes javascript or image beacons, if your browser displays it, the ad can send the category information to the advertiser/intermediary ad network/partners/whoever. If it's just a link, then you'd have to activate the link (intentionally or not), but depending on what information is passed to ad networks during the bidding process, there may be pretty significant information transfer anyway.
I can't use any VR I've ever tried -- I get nauseous after 5 minutes. Until they solve this, I'm all about monitors.
Oh, I think you're right. I'm too used to certain types of internet reflexes. Sorry GP!
It’s already great without these nitpicks. If those are your requirements, you might look elsewhere to have your communication needs met.
VR is a magical experience but for me it just isn't worth the hassle. VR is going to have to get to the "pick up and play within 60 seconds" level of convenience before I spend any more money on it. Getting my glasses to fit correctly in the headset is a pain. Adjusting the focus when I put it on is a pain. Software that tells me everything is working fine when I have no picture is a pain. Setting up the play area every time I start up because I breathed too hard since last time is a pain. Not being able to recommend it to anyone I know because they'll rely on me to sort out the problems is a massive pain.

When I tell someone to buy a Nintendo I know they're not going to call me to complain about how annoying it is to use.
Yeah, I probably should've posted my comment aside your comment instead of in response to it. Regardless, I was trying to draw attention to the tradeoffs involved in the formation of the current system beyond simply saying "that's how it is." Being explicit about how we got here is just as, if not more, important than understanding where we are. It teaches us how the current situation has and might yet change over time.
No, ad tech is well-known as the particularly abusive part of these monopolistic businesses.

It's a race to the bottom, and someone has to code them there. It's bad.
You'd think the fact that someone who hacked Trump's account could literally start a war or cause some other serious incident would make Twitter reconsider their apparently lax security policy, at least for extremely sensitive accounts like his.

But no, apparently washing their hands of it is more important than saving lives.

This sounds awesome. I've often thought the same - an enterprise version, even today with Chrome's ubiquity, could be a huge selling point for conservative organizations that want a signed support contract.

Even an Electron like package as well - but also sold with support contracts, and offered as FOSS to the community - would have lots of potential.
The law didn't ban recording police officers, it banned one-party secret recordings, and the police were treated the same as everyone else.
Add to that a wooden box with a small metal bars through which I could glance a couple of chickens that were being transported by the family, in Vietnam. Amazing.

The rate of children deaths or severe injuries caused by motorbike accidents must have been over the roof in these countries.
Man. Von Braun? That’s not someone to name anything after.

Please read Operation Paperclip by Annie Jacobsen.

What Von Braun did was beyond horrible so much so to make the death camps look less bad in comparison, which is really saying something.

They plowed through people making them death march then dig huge underground missile factories with their bare hands, then had them make missiles to kill their families and to help their enemies try to win the war, with the majority of them dying in the process.
> they redirected a ton of servo engineers to focus on VR/Magic leap, ffs.

That was the straw that broke the camel's back for me.

Huh. So it's basically a rotary 2-stroke engine?

I'm curious what the emissions look like. And I'm not sure if the apex seals actually change how much distance they rub over (though stationary may be enough to make them easier to deal with, and probably cheaper to replace the rotor rather than the housing if it gets scratched).
As an example if still were to heat and cook primarily with wood fires our cities would be choked with even more smoke than they have.

A counter example is cars, cars have come with new technology and as such they have increased our emissions. But they have lowered their emissions overtime. Cars will continue to get more efficient and cleaner.

This is the trend the more we advance the cleaner our technology gets. However we also seem to use more and energy as we expand our numbers. There are two options, reduce our numbers or increase our efficiencies. I rather like humanity and the freedom to procreate so I put all my eggs in the efficiency basket. The only way I know that increases efficiency is to develop new technology.
N95 masks lose some efficacy in a few hours as they get exposed to humidity. But they can be "recharged".

That’s going to be hard to prove. You’ll need to prove the cost of marketing went up when it actually got cheaper due advances in targeting. Google has a legitimate argument that owning vast digital properties allows them to provide more effective targeting and a cost savings to companies.

If you'd like to, you can shoot yourself in the head repeatedly with a nailgun. Don't expect any sympathy from me afterwards, however, when you're whining about how bad your head hurts.

What you describe is a problem the organization has created for themselves. If they can't also come up with a solution for themselves, well, that's their problem, I guess. Stupid hurts.

As long as they're only shooting themselves with the nailgun and no one else, I'm fine with 'em doing it. Hell, I'd probably show 'em how to load it.

The only experiments that we've done are earth based and involve horizontal acceleration. Sounds like we need to do some real life space tests! Maybe we can get something going with a central weight and a tether so the test pod can rotate around it at high speeds.

Also, I recall there being studies into changing how the inner ear is reacting to movement. Maybe someday space goers will have implants to calm the inner ear against coriolis.

For clarification, it was the New York Post. There's no way the NY Times would have published that fact free piece. All legitimate journalistic outlets passed on it, including the Wall Street Journal (like the New York Post, the WSJ is owned by Fox News' parent). Even the author of the NY Post article refused to put his name on it and much of the editorial staff at the Post was against releasing it. In short, it was fake propaganda delivered to them by Rudy Giuliani.
Playing a lot of games doesn't make you better, unfortunately. Especially not in quicker time controls. It just cements your current habits unless you're explicitly reviewing, changing and working on aspects of your play. You have to be making the right choices, then you can work on speed.

Quicker time controls are REALLY good at producing a lot of games for you to identify patterns of your own errors, though! Take a given game, slap on stockfish, then check what tactics you're missing and what positional decisions you made that significantly impacted the bar. On an individual level, not so important, but if you start noticing trends in your errors, you can mass-puzzle the areas you're weak at, etc.

That said, this analysis only works if you know your openings. Contrary to the OP, if your openings are mediocre you can't learn that much from your games. Understanding a system or two in depth will help you develop a 'feel' for what positions are dangerous, which positions are full of potential, etc. At a certain point that intuition will stop requiring 10-15 moves of theory to be sound, and you can start free-styling.
Ex-physicists are still welcome. The mathematics involved is similar, and what’s more important, physicists have the right attitude to work as quants. “Hack and approximate until you can solve the seemingly impossible”. Of course, some genuine interest and preliminary exploration of the field are essential for anyone aspiring to work there, physicist or not.

Anyone have experience working as a salesforce developer?
I was wondering if anyone has had experience working both with salesforce or in a position that involved it's tech stack.

A lot of the information I've found from just a few years ago make it seem like a universally hated platform by developers, due to poor integration with existing tools and various cultural problems(a lot of salesforce only developers writing bad code, salesforce best practices being somewhat antithetical to industry standards,etc).

I'm also want to know how much of your experience as a salesforce developer was spent using skills/tools unique to salesforce, and how much was spent using skills/tools that are common to any developer job.

lastly, how much of what you did could be done from the commandline or via a text editor?

I have a lot of reservations about working with the tech stack, but I don't know how much of that is founded. so I'd love to get the perspective of some other developers who worked with it.
I've continually been stunned that there seems to be no political support for shortening and simplifying copyright terms and increasing the public domain for the good of all. Europe used to have what I'd consider a pretty common sense general term (at least for music) of 50 years after release. But even they abandoned that for reasons I can't understand. Everyone benefits from the public domain, so how can laws limiting it drastically be passed with little resistance?
Looking for best ad agencies for mobile aquisition
I saw an analysis about 7 years ago (Boulder startup week) that adequate spatial resolution, fps refresh and tracker response would require about 100 teraops of local processing power in the display device. At that time it was just one percent of that power. Apples family of top end ARM devices are closing that.

Another bottleneck was that standard graphics pipeline in GPU had too much latency to keep up with user movements.
> That went from a reasonable thing that might happen — you're temporarily prevented from boarding a plane while you are bearing a highly contagious, deadly illness that can spread to whoever you breath on — to... Now you're labeled a terrorist because you got sick?

To be clear, I am not talking about temporarily preventing sick people from boarding planes. I'm talking about DHS drawing their own conclusions from FDA/medical data. The scare quotes on "common sense" were meant to point this out. Preventing infectious people from boarding a plane is reasonable. That means FDA may very well share data with DHS and feel perfectly fine about it. But how does DHS achieve this? Do they diligently maintain a list of diagnosed individuals and scrub names when those people are healthy? Or do they re-purpose an existing mechanism that has the desired immediate effect?

The "no fly list" also contains terrorism suspects. These lists existed before Covid and contain names of people who have never been suspected of wrongdoing but just share a name with someone who is, or not, who knows. These individuals still live with the consequences of being suspected terrorists.

This is the terrorist connotation I speak of. It is not a stretch. Check out https://en.wikipedia.org/wiki/No_Fly_List#Notable_cases.

> Why do you think having at-home tests will suddenly result in labeling every positive case a terrorist?

I didn't say this.

> I feel like the main stretch of imagination here that I find difficult to believe is that everyone who contracts COVID (which will likely be millions more Americans) will be labeled a terrorist,because they took the test at home instead of at a doctor's office or testing site.

I didn't say everyone. In fact my hypothetical constructs a situation where minorities are disproportionately placed on the lists. The macro outcomes lead to micro outcomes which lead to further macro outcomes. This is systemic bias.

Regarding the difference between home and on-site tests: is the home test data protected the same way as other tests? How many people have not been tested because they are afraid of a situation like my hypothetical?

Can LEO get a search warrant for your home, find the testing device and retrieve the results? What if they search your phone?

I think this is a pretty good overview, an interview with the author of a recent biography. I am partial to your view.

I don't have a problem recognizing his achievements and celebrating his abilities, but using his name to honor him is going further than that.

There are probably still people alive today that had a parent that died in slave labor at Mittelwerk building his rockets. I can't imagine how awful this would feel for them.

Regardless of his achievements, his legacy should carry a stain.

Absolutely. The communication was worse than awful, and on top of that it wasn't even coordinated. Plus to make matters even worse instead of doing that all that the current US administration did was to issue gag orders to scientists.

Instead of organizing PPE distribution and informing people that it might come to mandatory mask wearing, the message was a very dumb "well, maybe, but really think of the shortage and well, it's a hard question". :/

“The establishment”
Your comment leads me to wonder if car safety laws also contribute to this. Back in the day cars were large and you could fit four kids in the back of a station wagon. In sedans, there was a platform behind the seats in the rear that kids could stretch out on (no seatbelt of course).
Start crash testing expired seats and compare results to new ones of the same make/model. They expire relatively quickly, so they would not be difficult to find. For example, our Graco Keyfit 30 expires after 6 years.
Children shouldn't be lied to either.

Plus as far as I'm aware there was no lying, it was a very wishy-washy diversion, woes about PPE shortage due to China shut down, and 5D chessing about trying to not worsen the shortage instead of giving a simple and clear answer, that "yes, they unquestionably help [healthcare workers use them for a reason!], but we'll be stockpiling every shipment for later".

Of course, but my question is how is it created... MacOS has a Hypervisor framework for creating VMs, which Docker is using. But I don’t know enough about those internals to understand how they are getting an x86 VM on an ARM host. I know it can be done with qemu emulation, but does that still need the MacOS hypervisor framework or does it run as a normal user process?

These are the questions I’m trying to figure out...

> SHA-1 is only broken for collisions

Only… broken… for… collisions.

This is going to be my last reply to you, because this response is so confused that I think you're beyond help.

SHA-1 is used to validate long messages.

1. The sender, Alice, computes the (relatively short) SHA-1 hash H of a long message M

2. Alice cryptographically signs the hash H with a signature S

3. Bob can verify the whole message by verifying that the hash H is correctly signed, and then re-computing the SHA-1 of the entire message M, to verify that his computed hash matches Alice's hash H.

If Eve can compute a "SHA-1 collision," Eve can make a fake package X (like, say, malware instead of a real software package) that has the same hash H as the message M that Alice has signed. With that, Eve can trick Bob into accepting her malware by presenting Bob with her fake message X and Alice's real signature S. This works, because Alice really did sign hash H, and X and M have the same hash; their signatures have "collided" with catastrophic results.

To say that SHA-1 is "only broken for collisions" is to say that SHA-1 is broken for PGP.

Anyway, I'm done here. I hope we both agree that you deserve PGP.

Not everyone lives in an area where that is true, nor can everyone just afford to replace $20 helmets on a regular basis.

Compulsory helmets just for cyclists is a bit arbitrary too, since pedestrians and car occupants would also benefit from helmets, and at least pedestrians are likely to encounter the same exact crash scenarios which cyclists encounter where helmets are necessary (e.g. pedestrians can also get hit by cars and flung a distance)
