That is not true. The US does not block Cuba from getting to the internet in general (https://ofac.treasury.gov/media/912206/download?inline), although it blocks most commerce in general under its embargo. Your linked webpage is a Github policy restricting the availability of Github Enterprise Server and Github Copilot in Cuba, not the internet.

Castro wanted to provoke a crime wave in the US to tarnish the reputations of those Cubans living there. (source: I was one of those Cuban Marielitos that arrived in 1980 in one of those boats).

I can't help but to see a parallel with the out of control flood of migrants (some of them potential legitimate refugees) Turkey let into Europe in order to put pressure on the European Union back in 2015.
I've been using this for the last 3 weeks and it works really well. It has blocked 21 spam calls up to now. After the free week they charge $30 yearly or $4 monthly.
You can set the spam calls to be answered with selected funny time-wasting recordings, but since that would be embarrassing if I get a call from a professional contact, I set them to be answered with a plain fax tone.
Now I am back to being able to pick up all calls that ring.
Lander used to be the first game I would program when I got a new computer as a kid. I remember writing it for the TI-99/4A, Commodore 64, and the Amiga 500 (in Modula 2). Your game brings fond memories of those simpler times.
Amazing what you can do these days with the tremendous speed of computation available on modern hardware, even with the js13k constraints.
No, the tool works like a brainwallet. The seed phrase determines the ethereum public and private keys. That way there is nothing else to save, no file backup is necessary. Knowledge of the seed phrase is sufficient. That's a feature, not a bug.
It is not like gpg where the private key is independent, stored on disk and encrypted by the passphrase.
The user messed up in that he didn't understand that he needed to use a strong passphrase or it was possible for anyone in the world to guess it.
>An early old-style brainwallet was created by by memorization of a passphrase and converting it a private key with a hashing or key derivation algorithm (example: SHA256). That private key is then used to compute a Bitcoin address. This method was found to be very insecure and should not be used. Humans are not a good source of entropy.
In the video the researcher claims that they can build a significantly smaller/cheaper tokamak with HTS (high temperature superconductor) materials technology that has only became available in the last 5 years. Even if ITER is built not using HTS, can HTS be later retrofitted into it and therefore improve its performance down the line?
These are certainly the painfully obvious questions aren't they? Hartwig claimed that HTS can make existing designs either smaller or more powerful, so what about ITER?
And yet it isn't addressed, and it -- somehow -- doesn't occur to anyone in this MIT audience to ask. Even if one wished to argue that ITER is committed to a design and shouldn't be altered at this point it would still useful and compelling to at least compute how much better the ITER reactor might be... but nothing like that happens here.
I imagine that any person endeavouring to earn a place in fusion power research (at least at the university or government level) needs to be careful about questioning ITER design. At the moment ITER is the home of many of the worlds leading fusion power minds and all of the best funded ones, so you'd better have your ducks in a row. The fact that the question isn't directly addressed is probably an indication of just how certain the HTS proponents are about their proposal.
One of the best parts of the talk were the photographs of the unknown alloys ("tokamakium") being deposited on the surfaces of a tokamak plasma chamber. Interesting things.
ITER has done heroic design efforts over the past few years. But you'd be disappointed how small the resulting changes were, but they were heroic efforts. Things like feedback systems for plasma containment. So to your question, the answer is no. ITER cannot be retrofitted to use HTS materials. Effectively they cannot change the materials they use, nor can they change the shape of the superconductors. If you can't do that, there's no real point to switching to HTS supply.
The problem with ITER is that it's being half-ass funded. It's only enough funding to build it over 50 years or so. We could spend 3-4x the amount one year and have it built in 2 years instead and we wouldn't be asking these sorts of questions. We would know (that it doesn't work - I'm not a believer. However, I do agree that a massive amount of plasma physics will be learned with it after it fails to Q>1).
This happens today in Cuba, where many of the same techniques of repression were copied from East Germany.
As a young Pioneer I was told to inform on my parents if I heard any talk disparaging the government or Communism at home. There are neighborhood organizations called CDR (Committees for the Defense of the Revolution) that know what everyone is doing and will report any hint of dissent or any suspicious meetings. Snitching is encouraged as the patriotic duty of every citizen.

This is true of most countries, differing only by degree. A state has two choices for internal security: a small professional force that reacts quickly to flagged problems or a full scale surveillance state (as the Russians had in Moscow, where it was extremely hard for agents to operate due to the sheer number of KGB staff). The latter solution is usually not applied, or applied only partially, due to being prohibitively expensive even in a modern state.
For example, the FBI only has 35,000 employees. Even if each was dedicated to surveillance, that would be one employee per 9,000 American residents. Instead, they rely on the population approaching existing civil services (police departments, fire brigades, city halls) with suspicious activity; those that look genuine are further investigated and acted on.
The French government has recently published posters and a website [1] encouraging members of the Muslim community to highlight any recent radicalisation candidates. This obviously follows recent events but might also be linked to the systematic defunding and shifting around of internal security organisations (RG, DST, DGSI...) in the last decade or two resulting in the loss of the HUMINT network within the population. That FBI ratio, calculated for the DGSI? 1 employee for 20,000 residents.
Except that snitching about unpatriotic activities does not happen on a large scale here in America. People are far more interested in their immediate, personal safety and the safety of their property than monitoring their neighbor's patriotic tendencies (or lack thereof). Big difference.
The 80% poor may have had their standard of living raised by the revolution in 1959 but the rich and middle class had it lowered. In the 55 years since, the standard of living of the middle class and opportunities for the young in other similar countries has advanced past Cuba's while Cuba has stagnated and remained a 1970s soviet-like low-tech state.
I'm 46. I do agree that I felt smartest around 22-25, I was able to recall stuff quickly and think faster than now and absorb new information faster, but that's just raw calculating ability and short term memory. I have noticed over the years a slow decline, and now I feel about 10% less smart in that sense.
However, over the years I have gained a large array of mental tools, techniques and knowledge that have vastly expanded my abilities. I am a more competent programmer now, as well as a more rounded person. We will see if that holds up for another 10 years.
I disagree. There is a larger need for skilled workers: that's why they command much higher wages.
I think dmk23 is right. Since Obama got elected there seems to be a higher rate of denials for H1B applications and renewals, without clear guidelines why. Looks like pressure from above. See http://www.indianexpress.com/news/obama-warned-over-h1b-visa...
It does seem like Obama favors unskilled immigration (amnesty for illegals and the like) over skilled immigration, which I think frankly, is stupid and short-sighted, pandering to his increasingly powerful latino (mostly Mexican-American) voters.
