Large proportions of coal plants spew uranium particles into the atmosphere. That's the radioactivity I worry about.

> Also, I'm always fascinated of the "Chernobyl was unsafe, today reactors are safe" argument. The exact same line was fed to us when Chernobyl was state of the art.

And yet the death toll of Chernobyl turned out to be a tiny fraction of what was feared, and a blib compared to the death tolls from coal and other types.

Two of the reactors kept being operated for years. That's how small of a problem it turned out to be.

> There are good reasons to think that it may indeed be so this time. But the nuclear industry has lost all trust and all right to demand anyone ever trusted them again.

On the contrary they have demonstrated that the plants are safe enough that even in face of utter incompetency and criminal levels of negligence, nuclear disasters are manageable.

Unlike, say, collapsing damns, or coal plants that kill during normal operation.

I think we need to compare the benefit the USA's population gets from this Trillion-Dollar spending with other possible program like free college tuition[1] who would around 70 billion/year.

I think democracies need a tool that help explore and explain what we gain from a law/program and what are the cost associated. But consequence and indirect cost is difficult to foresee: Obamacare (ACA) increased the number of people going freelance (author, artist, start-up ... ) because they were able to get insurance without a part-time job.

Dynamic routing is fascinating, but also potentially frustrating for the rider. Your trip to work could take 10 minutes, or it could take 30 minutes, depending on who else wants to ride at the same time and how "dynamic" your bus routing gets. With a scheduled service, at least you know when the bus will show up. Of course, if it only runs once an hour and not at the time you want, you may still opt for the "flexible" option, but it's not guaranteed to be a win in all cases.

Jobs criticized Gates saying he'd be a better product designer had he spent more time exploring individual pursuits such as what Jobs did--spirituality and psychedelics.
The point is more that this "company" is most probably run and operated by a single person. Hence he is being upset with not being able to answer support questions at night and being forced to deal with every customer professionally, while being busy with a bunch of other things. But this is probably also calculated into the price of the product, and the fact that its just a garage door device.

If it were some medical device, you would expect that its supported by a large company, the device has gone trough mandatory certifications, etc. But that would also show in the price of the product, or the volume at which those products are produced and sold.

The mistake is expecting that every gadget maker provides service such a multi-billion dollars corporation can. It simply can't, its a single-person company and that person has its limits. So you either have to deal with some roughness, or you dismiss everything not backed by a large enough company. Not that big companies can't be assholes, they just know how to be assholes less personally.

I wonder if there's some research on this somewhere.

Organizations like NASA or the entire US military apparatus are also government-run, but you never hear free-market conservatives argue that US military sucks or is inefficient.

On the other hand, there are plenty of private organizations that are universally hated, like Comcast, American Airlines, or Bank of America, which are also huge, bloated, and have tons of waste internally.
> I'm guessing that at nine nines that is pretty much a one anyway and it would not even change a single pixel on the screen.

There used to be a bug with flex-wrap: wrap; where an element would wrap to the next line while it should have fit. You could fix it by instead using width: 25%; use width: 24.999999%; so it would be 25% on the screen but it would fix the problem so it didn't wrap to the next line. So you should look out with this.

Sounds like you’re main concern is high availability (HA) and scaling, things Cassandra certainly does well. But if you are also interested in data exploration and complex queries, Cassandra might not be the best choice. I think there is certainly a part of the spectrum here that is not well addressed by something like Cassandra. A future clustering version of TimescaleDB will provide horizontal scale out and solutions for HA, btw.

Also, regarding vacuuming, TimescaleDB does not suffer from it much under the normal workloads it targets because time-series data is largely immutable and deletions typically happen at the chunk level (i.e., dropping complete tables), avoiding any vacuuming during deletes and making wraparound vacuuming more efficient.

I don't see why that's a problem. Your comment basically reads: "Governments could run things more efficiently, perhaps, but you have to figure in that they'll treat employees with a minimum level of respect and dignity".

Unions and pensions and oversight are good things that help ensure people are treated fairly (or at least, better than they otherwise would be). I want my tax dollars spent giving locals a decent retirement, and not going into some California VC's portfolio.

And "no easy allocation of resources" strikes me as a good thing as well. This is public infrastructure. People depend on this for their daily lives. The last thing we want is for it to be easily unallocated.

>> expect 1/100 programmer is able to understand/do this properly

> Personally, I'll never accept such an argument as a valid reason to judge the quality of a programming language, unless we stop considering the amateurish programmers when computing the average.

When I say 1/100 C++ programmers are able to properly understand aliasing rules, and confidently use `restrict`, I was already talking about professional senior programmers. If you consider the whole set of C++ programmers that would drop to 1/1000.
We can discuss the numbers, but from my experience working in some very low level areas where you would expect C++ (or C) developers to know that kind of thing, I would say 1/10 would understand really how `restrict` works.

On that basis, I would say that, yes, C++ does not a good job at handling the aliasing of memory locations, since the required mental mumbo jumbo required to declare aliasing properly is too consuming for even experts.
This can be regulated.

>Basically in any reasonably capable enemy airspace, you need to fly with emissions control - ie. no radio, no radar else passive detection systems will find, triangulate and guide a SAM on you.

A cruise missile on final approach don't need forward radars or datalink back to base, and the same goes for almost any kind if missile used since the 2nd world war. Just because remote controlled drones don't work under heavy ECM don't mean the military don't have robots that can. And some of the US's drone use a directed signal towards an satellite instead of omni directional RF signals for control.

The Problem here is that stealth don't add a whole lot of value to the observe first then shoot kind of missions where you really do want an human in the pilot seat, so multiplying the cost pr air hour by a order of magnitude to get some level of radar stealth is the kind of economics that causes mission failures in real conflicts where real life supply problems dominate.

For the F-35 with it's dependence on BVR missiles for defense going silent also means that if it can be spotted by a ground observer(which it likely can) it faces a high risk if the enemy have enough time to scramble an interdiction patrol into visual range, a tactic that was perfected by the RAF doing the battle of Britain(using radars that could probably see the F-35).

And without the decommissioning, vast amounts of money spent on the decommissioning could have been spent on renewables to replace coal instead, and far less coal would have still been necessary in order to compensate for the decommissioned capacity.

It also meant less capacity available for export to countries whose fallback is fossil fuels from elsewhere.

The German decommissioning alone is likely to have been a far greater public health disaster than all nuclear incidents in human history combined many times over.

I want to add that in my experience, it is not so much about 'time' as an objective thing. Instead, especially for dev work, I would argue it's more about 'energy' (or 'focus', 'attention', 'willpower').

In a similar vein: Beaker notebooks (http://beakernotebook.com/)
In the US, the government took over public transit, usually after making life hell for it, and then proceeded to not adequately fund maintenance.

NYC is a great example. In exchange for access, two companies signed contracts with the city that limited prices to $0.05. They built a large portion of the existing lines and made a good chunk of change.

But the City wanted to own them, and inflation stepped into the picture decades later. Turns out, a nickel wasn't worth the same anymore and couldn't cover costs. Rather than allow prices to rise, the City bought up the two companies while building a third system (the IND). It also doubled fares after unifying. Hmm....

Then it put out an elected board to vote on fare increases. Guess what the winning stance was? No increase. Eventually the system decayed as the subsidies didn't cover maintenance and deferred maintenance eventually became a major issue. The system today still has 1930s and 50s technology.

If anything, the US public transit systems (which had similar stories in other cities) are evidence against American governments running infrastructure.

We are underfunding other important pieces of infrastructure from roads to bridges to sewers, so the next few decades should be fun as cheaply built suburbs deal with infrastructure costs rising.
The player wasn't the world's best IIRC. So its kind of a click-bait article. I'm sure the AI does well, but when I saw the match it was very mechanical. I feel like if a human played against it enough, maybe a flaw would be found.

AIs have significant advantages in reaction speed however, so I bet that a properly-programmed AI will beat any human. If an AI is reading from memory (while the human reads from the screen), a decently programmed AI will almost certainly win.

The question of whether or not an AI would beat a human with similar lag delays is an open question however. That paper didn't seem to have any lag delays programmed into the AI however, and was just reading from memory IIRC. I don't see a fair way of doing this however: human reaction times are based on mood, emotion, and current state of mind.

Machines will have a consistent reaction speed, and therefore a huge advantage in any twitch-based game.
Title 1 federal funding is $1000 per disadvantaged student. It's an insignificant amount of money compared to state funded education. Any state funding is totally irrelevant because the states will decide that problems. Likewise healthcare is funded inside states. You're confusing the issues.

ACA premiums are a good point, as they do apply to permanent residents. Empirically this would result in decreases in costs due to preventative treatment, but politically it is a sticking point. Medicaid (not medicare, which is for retirees) is not affected.

Regardless, the point is not to engineer a perfect solution, its to make an improvement by moving the burden of illegal immigrants in red states to blue states. The burden is lowered more than would be otherwise be allowed. This would remove 90% of the burden.

>If you set a quota at the current number then you aren't actually solving the problem, because more will come hoping to get one of the slots and then you have more people than slots. If you set no quota then the number goes up even more.

The inflow of illegal immigrants is 25x smaller than the number of current illegal immigrants. The people who want to be here are already here. In economic terms the elasticity of human survival is very low. The supply is nearly constant regardless of how easy it is to get in and stay. 96% of illegal immigrants are here already. Even if it becomes twice as attractive to come into the US under this system, 92% of the people moving to blue states will already live in the US.

It is far more likely that this would be a minor attraction- the ability to get a social security card is a tiny improvement to your quality of life compared to escaping violence and poverty. It is far more likely that immigration, legal or not, will not be affected significantly. Even if this makes moving to the US 25% more attractive, 95% of immigrants will already live in the US.
These presentations from Google are pretty irritating at these conferences. If you're familiar with the SDN field (as most ONS attendees would be), this presentation is essentially nothing but bragging about the scale at which they operate.

There is no useful information in here to advance the state of the art, no new ideas, no publicly available implementations (closed or open source). It's just a very high-level architectural view of a large network given by people who are incentivized to present it in the most favorable light. And due to the lack of any concrete details, it's free from critical analysis.

>Espresso delivers two key pieces of innovation. First, it allows us to dynamically choose from where to serve individual users based on measurements of how end-to-end network connections are performing in real time. Second, we separate the logic and control of traffic management from the confines of individual router “boxes.”

The first has been done before at many levels of the network:

* BGP anycast

* DNS responses based on querier

* Done in load balancer

* IGP protocols to handle traffic internally while taking into account link congestion

I assume their framework gives them much nicer primitives to work with than the above, which would be an advancement in the field if we could actually see an API or something.

The second is very far from "innovation". This is the essence of SDN and this has been the hottest thing since sliced bread in the networking world since 2008 at a minimum [1] and even earlier if you look at things like the Aruba wireless controller.

> However, we felt that computing the determinant for all possible sub matrices is a bottleneck for this algorithm and ways should be found to make this more efficient.

That last step is obviously of exponential complexity in the parameters r and t. I wonder whether the algorithm's total run-time becomes more acceptable when that last step is replaced by a polynomial-complexity computation.

To me it looks like an O(log(n)*n³) algorithm should be feasible, by replacing the submatrix-determinants with operations on determinants on large matrices that are generated in a way that ensures det=0 when any of the sub-matrices has det=0.

Unfortunately I don't really understand enough about the remainder of the paper to actually see how the useful the algorithm would be with that "bottleneck" removed.

The 2 things I know of which come closest are:

- P3P, which describes various ways a Web site intends to use your data, and browser preferences for what to allow https://en.wikipedia.org/wiki/P3P

- Debian packages contain license information, and debconf can ask the user to read the license and accept/reject (in the case of non-Free software; Free Software can be used without agreeing to anything). The answers are kept in a database, so if a license has been agreed to it won't be asked again. This is similar to what you're asking, but assumes that there's a small set of possible terms, which projects/organisations reuse over and over.
