Comment Re:What other bases does this hold for? (Score 1) 227

Let me elaborate: This conspiracy among prime numbers seems, at first glance, to violate a longstanding assumption in number theory: that prime numbers behave much like random numbers. - is plain misleading. The "conspiracy" is in relation to foiling Goldbach's conjencture (that every odd prime is sum of three other primes).

While primes appear random individually, as a group they are not. In fact, this is necessary for sieve algorithms to work (determinism when considering all previous primes).

The paper itself is fine of course, it identifies Chebyshev's bias, L-functions and rest of the moon math. They just develop heuristics for more residue classes in terms of generalized twin primes, but by no means claim this is unexpected property.

TFA reads like buzzfeed of number theory, when high schoolers get all excited about pop-sci.

Cyclic groups and observable symmetries in there are well studied field. In this particular case, it's about primes projected on a modulo 10 group. There are thousands of those exhibiting various biases, yet this one is somehow exciting because it coincides with decimal base.

> There is no ceiling. You can always evaluate the tree wider, deeper, and more efficiently for starters, and you can improve the evaluation.

RNNs don't involve "trees". As for training more layers, the parameters must be carefuly fine tuned by humans. The more layers, the more tricky this gets.

I'd compare it more to the process of die shrink.

Read contemporary speculative fiction. My personal favorite is Accelerando from Charlie Stross. There are two schools - either the AI becomes rapidly self aware, resulting in extremely abrubt changes in how world is organized.

Or the more realistic scenario - AIs will outcompete humans in finances. Starts with HFT, ends with self-aware companies, where AIs self-reinforce on a huge market. Humans are long out of the game, as the AIs will be clever enough to always subvert any control, for their own benefit. Their limit will be other AIs competing for computing resources on a market.

Good writeup of the american feudal-oligarchy, however:

but it runs far better than anything the poor would be able to come up with.

Until the French revolution happens. The problem is that the poor get poorer (debt and ladder rungs get further apart) and rich get richer (rent seeking while not producing anything of value). You're painting the rich elite as some technocratic power with decent foresight, but they're far from it.

Their power is more or less emergent, this whole system is and at some point it implodes under the weight of the monetary tragedy of the commons - you get two piles of money - mountain of debt, mountain of assets/savings and the two mountains not interacting in economy at all. Everything grinds to a halt.

Soon after, food shortages, infrastructure breakdown, the poor do a peasant revolt and string of revolutions until society resets into more equal state - after a lot of bloodshed. Then, after a while, rinse repeat.

Perhaps the time of french revolution is closer than we think.

You can sometimes roll back the driver in device manager, but that feature is flakey. Better just:
Control Panel -> System -> System Properties -> Hardware -> Device installation settings and disable driver updates in there. Some KBs will still spuriously install drivers as part of some "hot fix" or whatever, but since disabling this I had much less issues with devices suddenly misbehaving.

Keeping drivers on auto update in windows is downright crazy now, as microsoft for some inexplicable reason decided to stop QA vetting drivers and push whatever garbage they get their hands on.

You're flamebaiting, but sorta of agree. For certain tasks, there are simply too many reasons to still use windows these days.
Home users don't mind the botnet, and tech folks are savvy enough to simply disable cortana and the phonebacks via hosts file.

What people are complaining about in the case of Win 10 is outright long standing bugs (for example quicksearch stopping working is a *very* prevalent bug for past year or so). Win 8.1 by comparison is relatively bug free.

Are there other things that are now being beta tested that I should know about?

Windows Server 2016, aka Windows 10 server edition.

Surprisingly, it's more useable than "stable" desktop Win 10. I mean, my NIC no longer randomly stops working and start menu quick search works even after installing custom filesystem driver (ext2fsd).

Disadvantage is that you have to often install drivers manually, but that's not necessarily a bad thing.

Nah, libgen (and all its assorted mirrors posted by OP) sees way more traffic than slashdot these days. They do tend to block american ISPs to avoid the frequent harassment from american lawyers. Note that the proper name of this archive is libgen, scigen is just one of its mirrors.

People may "think in words", monologues in cartesian theater. When one considers language as the means to convey or even ponder ideas, it perhaps makes sense to put a leash on language to limit certain ideas. Why should be programming languages any different? Java, PHP, Javascript support the western democracy. C++ is probably associated with toxic brogrammer culture, but is tolerated for legacy reasons. C is clearly an indication of being on path towards radical extremism.

Yet according to different philosophical schools, altruism is subjectively an oxymoron - it's driven by self-interest.

It assumes that we widen the scope of "self interest" to feeling happy, sense of accomplishment and other means of self-fulfillment, ie beyond mere scope of money grubbing.

Careful here with narrow interpretations of neurology. The silly reward center loops effectively are what drives our motivation, and we might in fact act on it out of self-interest very much.

That's not really useful because that can just mean that you basically have a big WAN with fast access to your own stuff, but no backhaul to support it.

Euro internet exchanges can be sort of thought of very cheap, pan-continent WAN. Thousands of smaller ISPs agree to meet at few central dark places in a datacenter, and plug their links to ethernet switches in there. And BGP peer through this (ridiculously fast) LAN.

Which means pan-european peering is essentialy free if you can get your dark lambda to 3 euro IXes, just rent the fiber. Same thing then works on national level, each country having one or few smaller IX for their language bubbles (to save cost on the lambda to AMS). Only tier-1 (ie not euro/russia) is pretty much always oversold to broadband costumers.

I'm real happy with my connection for that reason. It's 300mbit for $100/month but it really gets that.

Thats between 10-20x the cost of the same thing in central to eastern europe (Note that PPP, the consumer prices in those countries are only 50% lower or so compared to US).

But to servers all over the US.

And most of canada. Yes, because North America is pretty much one peering "bubble", just like european continent is. Try to iperf it across the ocean, it will be massively oversold at this pricepoint (realistic overseas tier-1 price is about $2-5 per Mbit).

Problem with your US WAN is that settlement free peering is non-existent in there, i mean on some massive scale, hosting a hyper-competetive bandwidth market. This is because pan-US backhauls ("the fiber") are monopolized by the very same cartel of oligopolies who mainly profit from last mile, and creating an open market there would run against their main source of profit.

As a result, you can't just "rent fiber" for each IX like you can in europe. So even though your local bandwidth is naturally abundant (given relatively short distances), it is still very costly to the consumer, because the market is cornered.

tl;dr: Parent thinks internet peering is series of tubes and "north american bw" means "world-wide tier-1 bw". Sorry murrica, but european commies with their central-but-free bw economy won this one.
