How did you come across these two arxiv preprints? Both are far from astrophysics. One is highly speculative theoretical physics. The other shoots down previous work that was highly speculative theoretical physics.

> astro-ph/2102.07769

This is about a particular model of dark matter that unlike in the standard cosmology is hot and has a particular radial profile within galaxies and outside galaxies undergoes a phase change to a uniformly distributed cold dark matter.

Tracing the gravitational collapse consequences of a theory whose characteristic matter distribution does not concord with observation (it breaks when the radial symmetry breaks, as in galaxy-galaxy mergers, lumpy galaxy clusters, and so on) is interesting but doesn't say much about astrophysics.

The preprint itself was the basis of a workshop talk on speculative physics, and the workship was literally titled in the form of a question ("What Comes Beyond Standard Models?")

FWIW, I had never before this heard of Bled Workshops in Physics, and I still don't know (after poking around in citeseer and the like) whether it is an event in Slovenia, or just named after Bled, Slovenia.

> hep-th/0710.1735

I don't understand why this is in hep-th rather than gr-qc as it is manifestly about a semiclassical model, with a peculiar form of quantum matter used to study gravitational collapse.

The paper is essentially an obituary for an idea for a toy quantum field on a classical curved spacetime that might work better than the simplest toy quantum field that has been in use since at least Hawking's 1974 work. The original work [hep-th/0205.319] introduces this toy model containing analogue to electromagnetism, and found that they could only form black holes under certain conditions. These additional complications, your linked paper's authors argue, aren't helpful even under those certain conditions, leading to things like naked singularities away from the horizon (p.20).

The paper's central purpose is to narrow the viability of this family of toy matter; in the authors' words (p.2.), "In this work we address the following question: Are there other static, spherically symmetric black hole solutions for the MTZ model, satisfying the dominant and strong energy condition between the event and cosmological horizon, besides MTZ1 and MTZ2? Using a combination of analytical and numerical methods we conclude that the answer to this question is negative." (In the very next paragraph they point out that MTZ2 has already been shown to be unstable with the addition of spherically symmetric masses, and that they will show that MTZ1 has the same problem).

The final paragraph of p.20 is pretty damning, and declares the low-energy-string-theory MTZ idea dead. ("M" is also one of the authors of the obituary). And so this raises my second question:

Why did you link this paper?

In my view does not support your statement that there is "a huge hole in black hole theory right now", but am certainly interested on what motivated your choice of that paper in the context of the questions tsegratis asked. Neither paper seems to go anywhere near answering those questions.

I'm also slightly unsure that Iris -> Hash is correct, I don't see why it wouldn't be Iris -> [Hash]. Maybe scanners are that good but I'd have thought depending on things like light reflection you'd end up with different hashes. Maybe not!

> Even at 80k, the govt is still losing money.

Government shouldn't be run for profit, frankly it should pay for the entire connection.

If the government is going to insist on making money, then it should operate nationalised utilities, which provide a baseline service and cost, and if private enterprise can compete with that by offering a better product and/or cheaper service, then all the more power to them.

Having a situation where a single commercial entity has a monopoly position seems to be the second-worst option, just above "no service at all".
I think the Ontario story was misreported. Here is a long article trying to correct the record.

That's orthogonal to the point. Here's the scenario:

1. User has a "fake" biometric A, generated via GAN or [1], that's cheap and easy to produce.

2. Suppose they can present A to any orb device, generating hash(A), which signs hash(A) using its built-in private key as usual.

As long as the user can generate a fake iris biometric scan accepted by an orb, no other part of the system needs to be compromised for this attack to work.

Europe must face up to the chilling reality of Putin’s energy blackmail
The issue is that Apple has no accountability, unlike Google and Facebook. The only people supposed to keep Apple in line (the SEC and other three-letter agencies) have a mutual interest in maintaining an Apple monopoly.

Plus, it's not like Apple's been caught lying before. Remember when they had to take down their M1 graphs because they were so obviously deceptive? Or how about that time when they said 'political slave labor is not used to build iPhones!' and then we found out that political slave labor is used to build iPhones?

Unless Apple adopts some form of transparency, I don't think I have the capability of trusting them. I agree though, I'm tired of this arguement too which is why I'd really appreciate if Apple gave us something other than a whitepaper of how things should work with no way for security researchers or the common person to verify if that's actually true.
I would argue that the people who find themselves maintaining an application that is littered with custom shouldComponentUpdate's (et al) have a clear need for _some_ organizing state management principle, whether that's Redux or MobX or something else.

> Have you ever dug through a complex heavily nested application trying to debug a performance issue, only to find a custom shouldComponentUpdate method within every individual component?

The author specified a performance issue that they're trying to debug, but in my experience it's just as common to waste cycles debugging a "why is my component not updating" issue, which is the flip side of the coin: not enough re-renders, instead of too many. So the way I see it, it is not a performance problem per se, it's a state management problem; poor performance (from spurious rerenders) is just one of the possible symptoms of immature state management.

> On XP pair programming solves that very nicely, with a lot of comradery, but then you may also argue there is not enough individuality

No. That is literally extreme with zero individuality, zero autonomy and so on. Yes, there are extremes that are even worst then average in agile systems. But the extreme existing does not mean the average is somehow good.

> The small decisions should be made by the individuals of course, as group decisions are too expensive, but the bigger ones should be taken by the team, where it pays off, or at least a pair. I’ve dealt too much with bus factor problems in the past to want fully individual systems

Which small decisions are made by individuals in agile system? I am not aware of any, unless one is actively hiding what he is doing. That is my point. There is no autonomy, no mastery no accountability.

You said you was surprised that I found agile less motivating due to lack of above. And now you are telling me that there are systems which are even worst in that regard. Yes, I know they exist. And almost no one wants to work in such teams.

> It also happens on scrum teams a lot, the engineer the built certain part of the system is the only one to ever take tasks related to it and the only one that knows how to fix it, so when they are gone you have to deal with their mess

And now in agile system, I have to deal with everybody mess all the time. Because there is never a point in time when I know the part of system I work on well. I dont know what the system I work on is supposed to be doing. No one knows. So we all muddle through.
Ingredient prep is intentionally left out of recipe timings.

That would be nice. Some of the rumors about the Mini refresh point to something looking like the cube did.
When all the Mac line is on the M2 generation, I would love Apple to add a Mac Nano based on the M1 to the lineup. Tiny, at the original price point of the Mini, like $499. They could greatly increase the market share of the Mac that way while keeping their other product tiers intact.

Well no, as the article points out the NIH does not accept that interpretation and believes the research doesn't meet the criteria for being classified as gain of function under the relevant policy. Furthermore they were deceived by the researchers and at that point had not been given the research data, and the outcome was not expected or a goal of the funding anyway.

This might be an onpopular opinion on here, but I think that software (and hardware) development needs to be regulated, similar to pharma or other regulated industries.

> their service might exhibit problems with long-lived instances that they never notice because Chaos Monkey tends to terminate instances before they hit those problems

Tangential to the main point of the article, but I've seen this exact failure before! I worked at a retailer that would reboot all point-of-sale devices daily, after stores closed. The day before biggest sales day of the year, the team decided to leave the devices online overnight - sometimes a device would fail to come back online after the reboot, so leaving them on would prevent that sort of issue.

Of course, one bug or another reared its head after 24 hours of uptime. We ended up rebooting all of the devices anyway.
We're playing at sci-fi here, so don't take my response too seriously, but allow me to engage.

We know that e=mc^2, and so it's going to take a hell of a lot of energy to make enough mass for another copy of you. The only 'efficient' way to use a transporter therefore is to turn your 'original' body into energy, and use that energy to make the copy at the other end.
When I left Silicon Valley, it was to escape the bubble. What you wrote is what I felt. But in hindsight, I think "Silicon Valley is out of touch with the real world" is too innocuous. Obviously, it is, but a lot of the "elite" aren't just happily enjoying their bubble. They are intent on shaping "the real world", and they have enough resources and influence to be successful some of the time.

I doubt very much that the masses will be scanning their retinas into The Orb so that they can get Worldcoin, but these people are not going to stop coming for your retina, your DNA, even more of your digital fingerprints, etc. Sadly, they're eventually likely to get it all.
The point is that visibility state of the ticket is irrelevant and not connected to the resolving state.

> Where doesn't Rust 'compete' with C, and where is C the better choice in a kernel?

My opinion as someone who writes C for embedded devices and has started to play with rust:

C is better than Rust primarily when the C code already exists and the Rust code doesn’t.

Rewriting the kernel will probably have little impact in terms of performance for the user, the main benefits would be for developers, because Rust can be more expressive (less boilerplate and simpler ways to do some things), and it should have less bugs, since it’s performing more complex checks than C code would.

For me as an individual, I’d prefer to be writing Rust, I find it much more ergonomic (for my workflow at least). The main drawback I have is that no one else in my team really knows Rust (although that’s slowly changing).

Got pissed off on it on ioredis repo. Project touts its low open issue count but most of its closed issues are bugs unaddressed by the maintainers. Fucking stupid.
I sympathise with this, however, I disagree that it's harmful at all times. I think having it misconfigured it's definitely harmful.

The way I handle it is essentially never setting up automatic thread locking, and then, default to closing the issue, unless I add some specific label.

This is mostly for my sanity. There's a lot of issues where you get an issue raised with "x doesn't work", with little to no information. Great, I can't do anything with that, so I push back, and often you don't hear anything back. At this point, I close it (or rather, stale bot does after inactivity). If the user then provides more information and the issue is triaged and valid, I add a label, which makes sure stale bot does not close the issue.

If an issue does get closed, I'll get a notification if someone ends up commenting, and I can take appropriate action. It also gives others the opportunity to comment if they can provide additional context.

From the article:

“The migration of the geographic magnetic poles has accelerated in recent years, adding to the relentless task of updating systems and distributing the associated flight information.

The AHRTAG points out that updating aircraft declination look-up tables is a specialist and expensive maintenance activity that has no effect on the way an aircraft derives its directional information. It merely ensures the result is displayed as a magnetic value that is normally less accurate than the originally determined True heading.

And, if a future variation shift is sufficient to affect airport assets – like runway and taxiway signage and markings, plus instrument procedures, landing aids documentation, and FMS coding – at a major hub, the cost can top $20-30 million.”

They pay significantly less in Europe.

I was paid ~75k EUR (~87k USD) as an L5 at Amazon (incl. bonus), levels.fyi states you'd expect around $165k in the same role in the US. That's before taxes in both cases - literally half the salary for what is meant to be the same role.

The stock provision is also often much lower (less than half in my case compared to levels.fyi), and also faces higher taxes and the currency conversion when working in Europe but that can't really be avoided.

I was once told, by a car rental chap, that the rental companies don't make money renting out cars; instead, they make money by putting some miles on the cars in their fleet, and then reselling them at a profit.

He told me that the deals the rental companies have with the manufacturers are along the lines of "you will buy 5000 cars at a large discount, but you can't sell them until they have 5000 miles on the clock". So they buy lots of cars at a HUGE discount and then later sell them for MORE than they bought them for.

If this is true, then it makes sense for the rental companies to invest in EVs, because (a) there is customer demand for them, but more (b) because the market for second hand EVs is good.
