I am the primary author of this work. It's very hard to give a representative example, but I can give you a simple real-world example.

The mouse genome database is perhaps the only real world Postgres databases that is publicly available and isn't trivially small. It is available from http://www.informatics.jax.org. There are quite a number of publicly available datasets, of course, but this is specifically a raw pg_dump that includes indexes that are actually useful to the underlying application. A living, breathing database.

One of the test cases used during development involved restoring the dump, and then re-inserting the data with retail insertions (pristine indexes generated by CREATE INDEX are not very interesting). Something like the following, repeated for each table:

create table __foo (like foo including indexes);
insert into __foo select * from foo;

Afterwards, all of the indexes taken together (all indexes on all "__foo"-like tables) were about 15% smaller than they were when the same procedure was performed on a v11 Postgres. Since the database has many indexes on each table, the overall size of the database was reduced by about 10%.

That is only one anecdote, involving a database that happened to have a lot of indexes that each stored a lot of duplicates. And, this tells you nothing about how latency or throughput are affected for the application itself, which is usually much more interesting. Your mileage may vary, but this is what happened in the one real-world case that I actually tested. It was not cherry-picked.

Andres provided a link to some TPC-C benchmark results that I published, showing significant improvements despite the fact that that benchmark involves few or no duplicates in indexes. That's due to another specific issue with how we choose where to split leaf pages.

Overall, the best way to think of the v12 work is as something that fixes cases where Postgres previously didn't do so well. It makes performance more consistent overall.
>These days I listen to nearly all of my music on paid Spotify subscriptions.

This is absurd from my perspective; to go from the wealth of music created through history and countries available on what.cd such as the bootleg recordings of live music in a small Cairo bar to the limited and commercialized selection of what's on Spotify (and I do have experience with it), along with the fact you no longer "own" (in an informal sense) the music.

Music on the periphery, older releases and things people may not want to listen to are my lifeblood. I couldn't imagine being only able to access Spotify. It works for you and that's good - but for me (and I imagine quite a few other music enthusiasts) it's a totally different situation. Often if it's not on Soulseek or a torrent tracker then the only way for me to obtain it is through buying a physical copy, maybe from an online collector's marketplace like Discogs.

I might throw in an endorsement of the very new things one can find on Bandcamp too - I've profited greatly from that variety.
This is spot on and shows how much Silicon Valley is out of touch with the reality on the ground and dismissive of non-profits and government agencies that handle these sort of things.
It is worse in India.
You see a lot of popular and lesser known titles on Prime and Netflix, and buy subscriptions to those only to realise the content isn't available in your country.

I basically feel Netflix to be a rip off, and Prime's value proposition is faster deliveries, better discounts and a few free Kindle books.

And despite trying to use these services for a long time, I am still a fan and a proponent of torrents for such consumption as I get all the content, on time, on my terms and can consume it in a way I like.

Music, is sorted. TV and Movies isn't.
At launch Android was way more innovative at a systems level with per-application UID sand-boxing & a permission system and system-integration capabilities (broadcasts, services, intents, etc...)

iOS was innovative at a UI/UX level, definitely. But I can't really think of anything they did at a systems level that was at all innovative?
> a great web dashboard

That has not been my experience. I've been a Namecheap customer since 2005 (though now only for TLDs that aren't supported by my preferred registrars), and each time I visit their website it seems slower than the last. The interface is better than GoDaddy or 1and1 were the last time I used them, but that's a very low bar. I wouldn't call it good.

At one point they overhauled the frontend to add some loading animation to make it feel faster, but the backend has only gotten worse. Saving any changes is way slower than any other service I use with regularity.

I was going to take some measurements to back up this post, but...

I don't think mirimir was putting forth a fully-formed plan to upend global corporate takeover, and I don't think they're required to. All they were pointing out was the falseness of your implication that mirimir themselves (meaning, the people collectively) are somehow responsible for these broken laws. That blame was cast in exactly the wrong direction.

These broken laws are in fact operating as designed. As Warren Buffett observed, "there's class warfare all right, but it's my class — the rich class — that's making war, and we're winning."

Many people think of Braille as something that is not necessary to learn unless you are blind or visually impaired.

But having sighted people learn Braille has all sorts of positive indirect consequences.

For instance, at the very least, it is likely to help them keep accessibility issues more toward the front of their minds than if they had no exposure to it.
Agreed. Companies should do their best within a framework that’s defined by the population through politics. They shouldn’t create that framework.
As someone who works in technology in the public sector at the state level, let me just say that there is tremendous greenfield opportunity for software startups within existing government programs. Probably every program that government runs requires one or more systems to administer it; these are often painfully legacy systems. We are starting to see startups in some of these niche line-of-business areas (Medical Marijuana licensing, Senior & Long Term Care services, ...) but there are many other areas yet untouched.

Disregarding the misaligned incentives of for-profit enterprises delivering the kinds of services that are traditionally handled by governments, what evidence is there that technology can materially improve many of these services?

Many of the needs listed in the post (housing, education, food security, etc) are largely challenges of resource allocation. I'm skeptical that a web app can somehow make landowners willing to encourage increasing the housing stock in a city.
Eh? I thought they backed up their cars pretty well. Of course, opening up and fostering postmarket service would make people significantly less wary of a less established car company.

I honestly disagree. There are many people in jail now pre-trial because the government is worried that they won't appear for trial. As a result these people often lose their jobs and their housing -- even if it turns out they are not guilty. Better software and technology can help address this problem.

TPB was good for software, even if I owned legit software I would run the dongle free hacked version just because it didn't put you through hoops to check your license, giving a better install/start time.

But we don't run that desktop software now. Open Source is better than closed source for many applications, then there is SaaS. I am not going to want to get excited about Microsoft Word as nobody uses word processors these days.
Sounds really good. Particularly looking forward to native encryption and TRIM.

I think it's more about the way we communicate model results. In the media, it's communicated as absolutes like "The ice caps will be gone by 2100!"

In reality, the model results are communicated in uncertainty. More akin to "There's a 70% chance the ice caps will be gone by 2100 if the current level of CO2 emissions are not abated." That's a much less sexy headline to say nothing about the fact that most people wouldn't be shocked if a 3 in 10 chance event actually happens. Nate Silver does a much better job explaining this in his book "The Signal and the Noise"
> When non-profits succeed they have to ask for more money. When for-profits succeed, they fund themselves.

Having managed a non-profit and having worked at a very successful one before, this just makes you sound so out-of-touch it's not even funny.

Yes, some non-profits are driven by donations, but many are not.

> So it's far better for a for-profit to solve a given problem than a non-profit, as they are inherently more scalable.

If by, "more scalable," you mean, "less accountable," then you're correct.

In Europe politicians are generally not lawyers unlike USA, so the legal system cannot work in the same way. "Spirit of the Law" is what a non lawyer would assume the law to mean, since most laws are drafted by non lawyers. Legal battles are usually cheaper in Europe than in USA so it seems to work as intended even if you think that it wouldn't work in theory.

I listened to a podcast with the founder. She was impressive.

In terms of the impact of reminders, you'd be surprised. One of the student loan guarantors tried a model where they were paid more if they kept people paying their loans. Their program was very successful with just well-timed reminders and calls. It was pretty amazing.
Hmm - I'd reread the RFS. YC is not interested in running the government.

Look at what people routinely pay for in crowdfunding models, where all costs are 100% transparent and marginal cost is indeed generally low or even zero. You'll find a whole lot of indie stuff (very high-quality indie stuff in fact - because the same well-established reputational mechanisms that are active in the FLOSS community work there as well!), and few or no "actors/directors/musicians" of the mainstream sort getting any money there.

This is how it should be - there is simply no rational case for mindless entertainment ("TV/Movies/Music") that costs on the order of $10M or $100M to make!
They've clarified that the _first_ production run is very limited. There will be more production runs after that.

> Maybe we're seeing a push back towards performance over purity?

No, because performance is generally not a huge concern on the front-end. I'm not applying ML strategies to hundreds of thousands of data points, I'm trying to render 10 elements instead of 9. Performance is so rarely a concern that I'd always err on the side cleaner code than hyper-performant code. This stuff isn't even worth thinking about.
> But seriously, if you're at the point of having to rely on "the spirit of the law" it's pretty much always because the letter of the law is poorly drafted.

There is a truth to that. We need to rely on the spirit of the law because lawmakers, like everyone else, are neither omniscient nor do they never make mistakes. Letting people use unintended loopholes makes sense if you treat the law as a game, not if you treat it as a mechanism to achieve justice.
I was wondering that too, so I researched and the counterargument appears to be:

- Vietnam won a war with primitive weapons against highly equipped American military

- while the government can mass murder people with tanks and rockets, it is unlikely to do so. If in 2019 there was an armed uprising against let's say Trump, it could succeed.

> I'm not interested in theoretical arguments contradicting easily verifiable facts.

Which of these do you think is more likely: That Google knows the specific things that will cause it to be fined and just doesn't care about tens of billions of dollars, or that they're trying to but can't figure out ahead of time what behavior will result in fines?

> You can't turn the privacy violations off that Google commits for their own profit.

Then what do those settings do?

> Why on earth would I pay for a service I can get for free?

Somebody is paying for it. If you get them to stop doing that, what do you expect to follow?

> No, they aren't trading services for privacy since you cannot trade services for privacy in the EU anymore.

At which point you have the possibility of most people "voluntarily" sharing their data and the service continuing to be free, or the alternative that they don't and everybody has to pay for it directly. But the first one is basically the status quo and if you're angling for the second one then, again, why don't you just start there?

Finally native encryption! Might still be a bit of a dance to boot - but I'd much rather have small ext3 /boot and let zfs do disk/volume/encryption/compression on the rest. Oh, and while swap on a zvol is possible - I regret setting that up on my laptop. Traditional encrypted swap makes more sense for hibernation.

In ideal world, zfs would do all, and we'd boot straight in - but as far as I can figure out that'll require a new bootloader project. And I'm not sure how I feel about (full) zfs support in my bootloader anyway.
Why'd you name it Government 2.0, if you "do not seek to replace the government and its policymakers but seek to fund startups that create solutions that provide Americans the foundations for economic growth?"

For good reason.
>Is there any good tutorial or course out there on how to evolve from making a thing create random noises to actual music?

I can't name any specific tutorial, but what you need to understand are the ADSR (Attack, Decay, Sustain, Release) controls of samplers (and synthesizers), they're essentially sculpting tools for sound tones, and then the placement of these tones within a sequence, and expanding these sequences into song sections and an entire song.

If you want to to get somewhere quickly I'd start with mixing songs (DJ'ing) and then enhance those mixes with your own sounds, sections and later songs. Otherwise you'll need much longer until you're able to make a song, or get to something you're happy with.

Due to the ubiquity of music in our culture we're all experts basically, and hitting that bar is difficult if you start without a context like a mix that can guide your decisions.

Ableton is a DAW you could check out, it touches all aspects of music production and sound design and even DJ'ing, making it possible to approach production from different angles within the same program. Their learning resources are great.

Being familiar with programming could also help, because the way things are laid out and cascade is similar.
Isn't that mostly how Silicon Valley works too? Software developers like content creators are generally compensated well enough to live an upper middle class lifestyle, but their compensation doesn't necessarily match the value they create. Instead much of the value is captured by VC or production companies. This is because those companies are the ones who bare the largest percentage of the risk. If a project completely falls flat on its face, software developers and writers, actors, directors, etc still collect their paycheck. It is the VC and production company that lose money.

Even so, that idea merely expresses the hope that the prisoners can be educated out of their mistrust - which still seems like saying, 'the dillemma doesn't exist, if we fix the prisoners'.

(for the sake of argument, it looks like we're both assuming a n>2 group of prisoners.)

Also, the point of the dillemma is that only one prisoner has to act selfishly. If a subset of the group does cooperate, it doesn't matter because the one left out will take advantage of them all...and that risk increases exponentially as the size of the group increases, and makes the decision to trust even a subset of the group irrational.
At a very high level, yeah, most every rocket is just a tube that's pointy on one and and goes fwoom at the other. But this seems like it might be more similar to an Estes rocket than just that. The space shuttle's solid rocket boosters don't deploy the parachute by ejecting the whole nose cone, which is attached by a shock cord, and letting it drag the parachute out of the rocket's body.

That's really what I was reacting to. That, not only did they get to space, but they apparently got to space using a much more rough-and-ready design than I would have expected. The hacker in me loves that.
My advice is to not overthink it - just sign up for a class and take the plunge. It's a lot of fun.
