> apparently, there were significant political factors in the decision

As I recall the history this project is a near-perfect example of how pork-oriented-spending is not congruent with R&D projects. Everything from site selection to subcontracting was divvied up to appeal to the relevant congressmen. These unnatural constraints caused delays, logistical issues, and massive cost overruns. Their ability to solve those issues was hamstrung by the projects organization. Thanks to the dependencies they were a ways in before this all blew up and the project had to be stopped.

Building something like the SSC or LHC is fundamentally hard. Making someone do something that is hard while twirling a baton for political pleasure, much less getting critical components from two suppliers who can't integrate until construction, almost guarantees failure.

The correct approach, ironically, is perfectly embodied by the post WW2 machinations of the US government... Make the goals clear, dump appropriate money in engineering and technology organizations, let the nerds figure out the devlish details, and enjoy your A-bomb blowing up on time and schedule.
The versatility stuns me to this day

A word of caution: Many (most) IRC spambot detectors check if your connecting IP is also running a Dropbear SSHd service. This can cause you to be k-lined in some instances, and it's not immediately obvious to basically everyone why the anti-spambot bots are flagging your connection. Of course, this isn't Dropbear SSHd's fault. Just something you might want to keep in mind if you use both of these things.
If your phone is rooted, you can use e.g. Linux Deploy to install a full Linux distribution. Then, you can set up regular ol' OpenSSH, mount /sys and /data under the Linux chroot, and rsync as usual.

I use this method to rsync to btrfs snapshots (+ raw copies of non-filesystem partitions) to make daily incremental backups of the entire phone. (Restoring said backups is a bit more involved, but I verified it's doable.)
Golden words. This is the cycle that keeps repeating in complex production systems.

A solar "furnace" for air heating is just a box with a collector (most efficient ones are regular black insect screen collectors), which makes them a lot cheaper than a solar panel. Depending on how you have to transfer the air into/out of he collector the price difference can be huge.

I am building one now where the material cost for 5 m2 of collector with ventilation will be just shy of $650 and then I am using a very fancy collector mesh which I am not even sure will bring much. The ventilation will also be expensive in my case. Similar panels can be made a lot cheaper, especially in the US where material is cheaper and more readily available.

That size would give me about 850w with solar electricity panels and I am counting on 2kw with my collector (if I can get air through it quickly enough).

For my size (5m2), the price difference is about a thousand dollars, and I will get twice as much energy out of it.

You should check out www.builditsolar.com

and search on YouTube for solar furnaces.

Edit: oh, and solar water heating is of course even more efficient. 300m 4cm matte black PEM pipe on your roof is an excellent 10kw pool heater, costing just a couple hundred bucks. Payback is just a month or two depending on how fancy you want it.

I was there a couple of years ago, and it seemed the country was already in the late-communism early-capitalism phase that Eastern European countries went through around 1990. This was especially visible in the tourism industry, i.e. with 'casas', apartments/rooms rented to foreigners. In this market, people were already getting separated into economic winners and losers, as often happens in this quick transition to capitalism. It seemed that people had a feeling what was happening, everybody seemed in a rush to get as much of the tourist currency that's pegged to the dollar, rather than the locals' currency.

> It would be so easy to make every building comfortable.

Every time there's a thread on air conditioning, we get smug comments like this, usually from places where the climate is so comfortable to begin with that air conditioners are the least necessary. Okay, Los Angeles needs them two or three months a year. Anyone from San Francisco, on the other hand, forfeits the right to talk about air conditioners in my opinion.

I'm sitting in a major metropolitan area in Asia. The temperature right now is 39'C (102'F), and can easily go over 45'C (113'F) in the sun. The humidity fluctuates between 50% at midday and 90% at night, and the temperature remains above 30'C (86'C) through most of the night, too. I would love it if you could make every building comfortable under these constraints. Hint: increased ventilation only brings in more heat. Any cooling solution that relies on evaporating H2O does not work, either, so don't bother bringing those Kickstarter gadgets here. Most of the old world is in the same boat. Coastal California is the exception, not the norm.

Adobe August 2018 Patch Tuesday address 11 vulnerabilities in its products
Yeah, one has been able to do this for some time now.

A few years ago I had a setup where (and I admit much of this was for the aesthetic purity of it, not practical reasons), I used a legally purchased copy of macos, copied it unmodified to my VM server, and, with a decent amount of effort, and a patched qemu (for the SMC thingie -- i donno if by now the patch is in mainline), was enjoying a non pirated, non modified macos on a linux host.

I even got USB and BLE passthrough working, so I could use the mac VM for iOS app development.

It was quite effective.

A more challenging project I did later (which I probably deserve some derision for not documenting and sharing) is "How to develop, sign, and upload iOS apps entirely from debian linux, entirely with F/OSS, no VM, no Xcode, just good ol' emacs and cmake". IIRC, there were very little Big Contributions I did, but plenty of assembling a large variety of other projects, bug fixing them, and making an integrated environment.

If you’re given share options they can be worthless after the acquisition is complete. I’m not sure exactly how because it’s legal and accounting practice. Hence the lawsuits.

If you have share options and you catch wind of a buyout, exercise (buy) the shares. That’s when you have a stake in the game.

You have to remember that the company that issued the options won’t exist (in the same form) once acquired, the options become worthless. Sometimes they’ll throw you a bone but that’s usually the bare minimum of what they can get away with.
Racist jokes, are just that, jokes. IMO it's ok for anyone to make a joke against anyone else due to a joke's harmless nature. Although yes, someone who is a racist (i.e will deny you a job because of your race, or hold negative stereotypes about you to your detriment) is more likely to utter a racist joke, but the joke itself is the harmless act. However I'm not talking about jokes. I'm talking about racist actions that are actually negative to the person on the receiving end, you know, the things that actually matter -- not jokes. It's bad for anyone receiving it. Whether you are denied a job, or an opportunity due to your race it is bad. For example, read up on Asian-americans being the victims of positive discrimination and having to earn more marks to get in solely due to their race. Typically these people are affluent and definitely not powerless and probably are the most powerful in terms of getting a place at an Ivy, I'd argue they are at the receiving end of a policy that is racist. Also remember, power can be localised. For example is it impossible for a white person to be racist in South Africa, because they are in the minority? Yeah I'd say so. Thougu under your definition - I definitely can say we can have a debate on that. Is it impossible for a black person to be racist in South Africa? No, according to my definition of racism and also according to yours (though you may disagree depending on how you believe powet works); whilst I imagine the average white person in South Africa is richer than the average black person, they dont enjoy much political power nowadays and they are in the minority in terms of people.

My point is, don't let people commit racist actions (I don't care about jokes) because they may have 'less power' due to their race.
I frankly don't understand all this fuss about it. It was a well known issue. Even I knew that, and I don't tend to follow such news. Now it's Trump's fault. Or the other conspiracies. Incredible how little accountability everyone has nowadays.

> Street cameras in particular seem to me to be a lot more about retaliation and crime solving rather than actual prevention. You still get murdered, but now society catches the killer.

Catching criminals is certainly a good thing to do. It may also prevent crime since criminals often commit more than one crime if left on the streets. Crime prevention is not the only thing that needs to happen. Compare with firefighters that will both need to prevent fires and put out the fires that happened anyway. There is also the perceived need for justice - "Not only must Justice be done; it must also be seen to be done." Cameras will help in this context.

Are cameras really a privacy problem in our GPS-enabled Wifi BLE cellphone tracking device infested world? A world where your face is tracked on every photo uploaded to Faceboo, and your Wifi and bluetooth MAC are logged in every AP you pass on the street and sent to advertisers and security agencies for storage and processing.

Crime prevention can be improved by using machine learning and AI. We may end up with a Minority Report style society. Is the prevention of crime worth the trade-off?

The only way to win is not to play.

It's an interesting idea but, if I understand it correctly, I don't think it would be able to capture the majority of particles emitted from the collision zone. Modern detectors are designed to be as hermetic as possible so they can capture as much of the transverse energy as possible. This is crucial because in the plane perpendicular to the beam axis (i.e. line of collision) the total momentum is zero. Thus we can use conservation of momentum to infer the presence of particles that the detectors struggle to find (like neutrinos). This, of course, only works if we're confident that we accounted for (almost) all of the particles coming out of the collision.

Here is a picture of a heavy-ion collision reconstructed from the CMS detectors to give you an idea of how much needs to be accounted for [0]. The light orange lines are the particle tracks in the tracker, the red boxes indicate the amount of energy deposited in the EM calorimeter, and the blue boxes indicate the amount of energy deposited in the hadronic calorimeter.

I should note that normal proton-proton collisions do not produce anywhere near this number of particles (what we call the event "multiplicty") but they can still produce a few hundred. Furthermore, there are, on average, 40 proton-proton collisions per bunch crossing (which is what dictates the 40 MHz rate). So every 25ns there is a bunch crossing and the detector "snaps an image". In that image there are typically about 40 different collisions. Correlating tracks to vertices is not that easy given these conditions and is further complicated by the fact that particles can decay mid flight, causing their track to suddenly change. It would be great if we could be absolutely confident about the physical quantities associated with all of the particles produced in a collision, that's all we would need to know and this is essentially what's produced in high-energy physics simulations. However, reality is a lot messier. In addition to what I previously mentioned, the interactions between the detector material and the particles themselves also creates a lot of noise in the system. All of these uncertainties make it infeasible to compress an event down to just the reconstructed physical quantities, there is too much uncertainty and I don't think it will ever be overcome.

Lastly, I should mention that the energy densities reached in the immediate vicsinity of the collision zones is high enough to destroy any material known to man. The center of heavy-ion collisions reach a temperature of over a trillion degrees. That's 100,000 times hotter than the center of the Sun. No instrument could ever be placed there to make an accurate reading. The best we can do is place detectors a decent distance away (IIRC it's about a few cm) and try to catch what comes out.

You also kill the batteries in shorter amount time if you do not limit the acceleration. The habbit of pressing the accelaration to the bottom will drain lots of power from the battery. It also encourages reckless/sporty driving. Best way to do this is on passenger cars is to have an eco/sport switch. On a passenger bus or truck you don't need a sport switch, since those vehicles are meant to be driven responsibily.
Docker offers a simple way to provision the VM - install software, configure networking, execute apps... Docker itself is not a VM or isolation, it uses other tools for that (linux containers in the past, not sure how it works today), it's value is in the ease of use provided by its tooling.
First of all, I would like to express my gratitude to the representatives of the community for their interest in my publication on the proof of the Riemann hypothesis. In addition, given a large number of questions, I would like to offer the community's attention to my publication on the study of the Riemann zeta-function by physical methods (http://ru.math.wikia.com/wiki/An_investigation_of_the_Rieman...). Since the interest also expressed about relativistic computers, I want to draw attention to the fact that, unlike quantum computers that facilitate the solution of computationally difficult problems, they can solve non-computable problems.
This is intuitively true, but is it also factually true? Many studies (https://broadly.vice.com/en_us/article/kze8qn/the-hidden-epi...) seem to indicate that, at least for cases of actual rape, it is not, and women are abusers at pretty much the same rate as men. This might be different for sexual harassment, but that's a claim that needs to be verified.

As it is, research and public perceptions when it comes to sexual violence against men are sorely lacking.

Reading through the article I got the impression that these questions were posed because they lead to more interesting questions. In fact, the last paragraph fittingly sums it up. "I pose these questions to stimulate deep thinking and further discussion."

Here's an example from the text of what she means: "In order to answer what is computable, we must consider the underlying machine (abstract or physical) that is the computer. Consider the Internet as a computer. What is a universal machine model for the Internet? Consider a molecular computer, a DNA computer, a nano-scale computer, or even a quantum computer. What problems can and cannot be solved through them?"
