It shows the author have a deep understanding of the fact that premature optimisation is the root of all success


Regarding storage, a single data center using only slow but dense storage (magnetic tapes) can store far more data than a data center providing regular web services.

Public information shows that the NSA has been active intercepting as much data as possible.

It doesn't require the budget of a FAANG to peek through a significant volume of internet data.


That’s not what the GP comment said though. They claimed that they are storing everything they can intercept, which is weapons grade horseshit.


https://en.wikipedia.org/wiki/Consensus_decision-making alternative political movements care a lot about how decisions are taken. For instance, authors like David Graeber consider that majority voting only makes sense in the context if backed by violence.


So what percent of people are required for "consensus" because it seems like 50%+1 to 100%. There seems to also be an implication that democracy is 50+1 when it isn't. It can require any percentage to reach a decision.

Those two words refer to the same "type" of system where the members make a decision by ascent or descent. Both systems require an agreed upon barrier of acceptance.

They are the same. The US congress reaches decision by consensus.


Consensus is strictly 100% agreement (or at least 0% disagreement). Granted, it's not always possible. But in some setups and given some objectives, it's sometimes possible to have a collective that finds compromises that satisfy everyone (consensus).


> Consensus is not synonymous with unanimity – though that may be a rule agreed to in a specific decision-making process.[1]

Yes a good thing to point out, however the American initiative was more successful, was it not?

Largely because raw numbers aside, most of the top talent wanted to avoid the Soviets and thus the US was the only logical option. That is, part of what made the American job on this easier is top German talent anticipated some "Operation Osoaviakhim" (or worse) scenario and thus sought out the US as the only way to get out ahead of it.

von Braun made major contributions to NASA. My understanding is relatively speaking, the Soviets got the scraps. Not that it made no impact, but just to say the impact of the Germans on the American space program should not be understated, and I don't think it would be accurate to assess the fruits of these two competing operations as equivalent.

von Braun and others had a major hand in the Saturn V. Who did the Soviets manage to seize of equal caliber?

https://en.wikipedia.org/wiki/Wernher_von_Braun


USA got the cream of the crop of the managers of the German missile program, while the USSR got the workers, who actually did the work with their hands and built the parts for the rockets. (One exception was Helmut Gröttrup, the head of the V-2’s guidance and telemetry systems.)

In fact, after the war the USSR has briefly reconstituted the manufacturing of V-2 in Germany, employing thousands of people, before transplanting this entire industry to the USSR. This dramatically lifted the level of Soviet manufacturing and relevant metallurgy.

von Braun's dissertation was on engine design and testing. But when he built the Redstone missile in the USA, he ordered the engine from a US company -- the engine which was already a generation ahead, compared to the imported German engines which the US engineers studied after the war.

Meanwhile, the Soviets have developed even better engines, completely on their own, though with the important parts built using the materials and the equipment brought from Germany.

So it is debatable whether having the German higher-ups and having a greater continuity with German design philosophy was a good thing or a liability.

It is less well known, but France have also imported a significant number of ex-Peenemunde engineers for their program. And their engines developed in a way different from both the American ones and the Soviet ones -- which definitively shows that although internalizing the German know-how was the starting point for everyone, it did not define the path of subsequent development.

Of course, the engines were not the whole story. The Germans took to the USA the advanced prototypes of the inertial guidance systems which were developed for the missiles that were supposed to come after the V-2. And the Soviets got Helmut Gröttrup. This did have its effects in both cases.


great comment, just wanted to add a little: all three countries were pioneering rocketry in the 20-30s, more or less in equal measure.

I don't know why this WW2 rocket discussion happened to begin with, but people here don't seem to understand that there is no magical inherent technical skill which is unique and irreplaceable. Experience helps to speed things up, sure, but it can be acquired by any program given time and resources, with no talent blockers.


> USA got the cream of the crop of the managers of the German missile program, while the USSR got the workers

That's a bit oversimplified. The Russians got quite a few important scientists and engineers in other areas (aircraft design, nuclear physics, electronics, radar, optics), they just didn't make as good use of them as the US (e.g. the 'American Germans' essentially won the space race for the US).


Talking about the role of V2 in the development of rocketry in various countries is more or less relevant to the discussion of Isar, because it was a major milestone, and it did influence all rocketry worldwide, in many different ways.

Rocketry may be much more talked about, but in terms of headcount is was a tiny thing compared to the number of German experts who were "invited" into all Allied countries after the war. Just France and UK had brought in about 3 thousand persons each. If one had said that this did not happen, that would have been an error. But simply not bringing this up at all because it is not very relevant to the discussion of Isar is fine, I think.

Debating who "won" the space race, and who "used" Germans "better" is not something that I want to do.


Also, `jj split` can use alternative tooling to the built-in TUI, whereas I don't think `git history split` can.


The VCR became widespread during the 1980s

> The industry boomed in the 1980s as more and more customers bought VCRs. By 1982, 10% of households in the United Kingdom owned a VCR. The figure reached 30% in 1985 and by the end of the decade well over half of British homes owned a VCR.


Another good one.

My impression of the VCR is not too many people managed to use it for DVR-style rescheduling live TV. Although it did have that feature. We mainly used it to watch movies that we had already been in the theater.

But, for sure, another fracturing. We weren't all talking about the nine movies in the theaters, but whatever we had rented and watched on tape instead.


My family used it to capture programming we couldn't normally be around for, especially late night BBC content on PBS. Pretty much all we used it for was DVR style recording.



My recollection was that the VCR's main selling point was the ability to record TV and play it back later, and I can say anecdotally, that that was the primary way my family used ours in the early 80s. Only later did the idea of Blockbuster and "using VHS merely as content distribution" take hold.


I wish you could disable fullscreen (enable the navigation bar) on Android though :-(


Joys of open source: you can add the feature yourself.
