> in 1960, the 23-year-old Russian mathematician Anatoly Karatsuba took a seminar led by Andrey Kolmogorov [....] Kolmogorov asserted that there was no general procedure for doing multiplication that required fewer than n^2 steps. Karatsuba thought there was—and after a week of searching, he found it.

Karatsuba's method is beautiful and actually quite simple to explain.

Suppose you want to multiply two 200-digit numbers. Write them as aX+b and cX+d, where X=10^100.
We want to compute the product (aX+b)(cX+d), which is (ac)X^2 + (ad+bc)X + (bd).

By the naive method, we'd end up effectively performing all four multiplications ac, ad, bc, bd.
Karatsuba observed that we can do it with just three multiplications: ac, bd, and (a+b)(c+d)
— and get our (ad+bc) as (a+b)(c+d)-ac-bd.

Doing this recursively (so that T(n) = 3T(n/2) + O(n)) gives Karatsuba's method, cutting down the n^2 time of the naive method to about n^1.58 time.

The gap between 3 9s and 5 9s isn't that wide. Gmail itself has already had ~4-5 hours of downtime for the year [1] [2]. A couple more hours and they'll hit 3 9s (99.9%) for 2019.

A small org can do about the same, and they're not paying what Google pays for infra and staff. Does Google have it harder at their scale? Of course, but they also argue they're better than most at it, at scale.

Nah, if plastic-eating bacteria were released to the wild, it'll be something between a huge annoyance and a civilization-ending disaster. Plastic is a wonder material, and while we definitely don't give it its due respect, it plays crucial role in places like hygiene and energy efficiency. Imagine if you suddenly had to worry about all the plastic things around you rusting.

Also yes, engineered bacteria and viruses are dangerous stuff, but that's the closest we have to a self-replicating robots today. I don't know what else the OP could have meant, besides making a joke. That said, if we change "self-replicating" to "cheap and mass-produced from recycled material", then the whole thing starts to make more sense.

the locked in store model has completely failed. both for ios and android it is a terrible experience compared to PC. you are stuck with only the search tools the hardware maker gives you, often designed in a user hostile way (ios brings up ads) and no way to bail out to a different store. as well the monoculture leads to a race to the bottom with garbage programs shoving their way to the top via misleading a dishonest means, and by sheer numbers.

i want no part of it. when a phone maker comes to the market without this locked down model i will buy it, and if windows goes this route i will drop it for linux.

I'm in the Nvidia Geforce NOW beta at the moment. It's fantastic. If you want to get in the beta it's running until early May. Invites are going out fairly quick at the moment (a friend just got on with a one week wait).

Their pricing is not released yet (the beta is free with unlimited use, you just have to disconnect and reconnect every 3 or so hours), it might be hourly or monthly.

They do not provide the licenses for games, you just log into Steam (or one of the other publishers launcher you have your games on) and play any of the supported titles.

I am able to play every game (Conan Exiles, PUBG) I've thrown at it on max settings and the servers are peered very well so it's very low latency to my machine and also the game servers I am using.

It's crazy to be able to play modern games on ultra at 60+ fps with a near-native experience on a machine I built 10 years ago.

UW has tried overall to be as supportive as they can be within the parameters of Washington State law and University rules. I did get UW to sign something a few years ago, but it was clear that whatever work I did on CoCalc had to be on my own time, not using any UW resources. There's much more to why I resigned than just my fear of potential IP issues (note: the issues are not worse by resigning, because I have been on 100% unpaid leave for the last three years, starting with a BSD-licensed codebase). An additional factor, which I didn't explain well, is that I would have to devote at least 50% time (so 20 hours a week) to work for UW, and this work would not be on CoCalc. Unfortunately, I have found that I am unable to do a good job working on CoCalc, if I have to spend 20 hours a week focused on other things. It's also impossible for me to respond to critical customer needs, server issues, etc., if I'm preparing to teach (or actually teaching) or in a committee meeting. For example, imagine that a 500-person course at UCLA has an exam coming up using CoCalc, and there is some issue with pushing out the exam to students, which I could easily fix if I could focus on it. I would feel terrible ignoring the UCLA course for a committee meeting or because I was teaching.
Data protection laws need to basically create this sort of ephemerality in collected data in that data is destroyed by law after a certain period of time. Outside of that we're a step away from a total surveillance state where everything that you do in any major city outside of your house is on record for eternity.

Here Louis Rossman talks about how all recordings that he has made using his Android phone's voice-to-text feature and Google recording all that audio for years and all of that is on record under his account.

So in terms of storage, if Google is storing that level of data. Then yeah we have the ability to store everything, forever. If that's what we as a society want to do.

You can use the "fancy math" version on all 8 bytes in the string simultaneously:

#include <cstdint>

uint32_t convert_hex(const char* s)
{
uint64_t a = *reinterpret_cast<const uint64_t*>(s);
a = (a & 0x0F0F0F0F0F0F0F0Fu) + 9 * ((a & 0xc0c0c0c0c0c0c0c0) >> 6);
a = (a & 0x000F000F000F000Fu) | ((a & 0x0F000F000F000F00) >> 4);
a = (a & 0x000000FF000000FFu) | ((a & 0x00FF000000FF0000) >> 8);
uint32_t b = (a & 0x000000000000FFFFu) | ((a & 0x0000FFFF00000000) >> 16);
b = __builtin_bswap32(b);
b = (b & 0x0f0f0f0f) << 4 | (b & 0xf0f0f0f0) >> 4;
return b;
}

Compiles to 30 instructions with clang, so 3.75 instructions per byte. (clang is one instruction cleverer than gcc) No branching, the only "complicated" instructions are bswap (__builtin_bswap32) lea, (the "multiplication" by nine) and one addition. Other than that it's all bit manipulations. (moves, shifts, ands, ors) However, I doubt it will pipeline well, the data dependencies are quite linear.

It has very little tolerance for inputs that are anything other than 8 byte hex strings. Do error checking elsewhere.

I doubt this would be faster in any meaningful sense in a real world use case.
That is amazing. Do we understand why aesthetics and intuition are so effective here? Or actually if that's even trueish in the general case?

Even if vaccines were honestly what their peddlers claimed, they are harmful and dysgenic. The weak should perish so the survivors are more resilient. Vaccines subvert this critical natural process.

This rule should be retroactively applied effective immediately, starting with anyone found to have a reddit account.
Counting French and Germans as a single population group doesn't really make sense, since their languages are far more different than, say, the different flavors of Bengali spoken in Bangladesh and the Indian state of West Bengal.

They can sell.

The locked in store model is better than than what we had before for the general consumer (at least iOS's, unequivocally is, IMO). The App Store might be bad for developers, but it's way better for consumers.

One of the most important needs to enable fertility is a temperature in which an infant can survive. In colder climates, that requires a lot more fuel input to heat homes, whereas in consistently warm climates, like the African countries to mentioned, they get their heat "for free", and therefore fertility is less constrained.

The heat poses other problems that affect survival rates, like tropical diseases, but the energy cost of fighting those is far less than heating homes.

The same observation applies to the agricultural sectors of those countries, which can be incredibly productive due to growing regions with consistently warm weather. It's how China and India can support such massive populations (both are largely food self sufficient). And it's also why Brazil can produce sugar cane based ethanol far more efficiently than the US can produce corn based ethanol.

Once this major difference is accounted for, however, change in energy consumption over time is a reasonable proxy for change in standard of living.

But absolute differences in per capita energy consumption fail to capture variations due to things like country size, transportation/energy infrastructure, and socioeconomic structure i.e Russia has a much higher per capita energy consumption than Germany, but a lower standard of living.

On a tangent, there's a lot of overfishing leading to depletion.

Sooner or later, countries need to start banning big wild fishing.

Another reason to ban is that it's hard to monitor catching practices. Some catching practices wipe out whole ecosystems in one sweep, including taking endangered fishes, seals, etc. The boats will know they will get in trouble for keeping it and will throw them back in water, but not all of them will be alive.

The company is not profitable, but it is "ramen profitable" according to http://www.paulgraham.com/ramenprofitable.html.

However, we're close to profitable. If we instead had only three employees (or paid ourselves less), then we would be profitable. If we had just one employee (me), then I would be making a LOT more money than I made working at UW, though I would likely be much less happy (the other three people working on CoCalc are fantastic!).
