You're right. Wikipedia mentions that Voevodsky's model is considered to be non-constructive since it uses the axiom of choice in an ineliminable way.

> The problem of finding a constructive interpretation of the rules of the Martin-Löf type theory that in addition satisfies the univalence axiom and canonicity for natural numbers remains open. A partial solution is outlined in a paper by Marc Bezem, Thierry Coquand and Simon Huber[17] with the key remaining issue being the computational property of the eliminator for the identity types. The ideas of this paper are now being developed in several directions including the development of the cubical type theory.

I'm getting confused because Martin-Lof writes at the end of this paper:

> I shall construct an object of this type, an object which may at the same time be interpreted as a proof of the axiom of choice...

Thus (Az)((..tx)p(z(x)), (lx)q(z(x))) is the sought for proof of the axiom of choice.

It would be interesting to see Bird have an offering to address the daily commute, something to the effect of Lyft Line. I'd be curious to see an Uber's Ride Pass [1] for scooters.

Where I live the scooters are mostly in very concentrated areas that few people would use them for commuting, either because they live in the suburbs (so far away it'd be impractical) or downtown (so close that you could walk nearly as fast as a scooter ride after accounting for sitting in rush hour traffic).

I think Garmin reasonably sees Strava as a boon to their business. Before it came out, most cyclists had simple odometer style bike computers rather than gps devices. GPS computers existed but there wasn't much you could do with the data. Strava should likewise see that services like Relive only increase customer satisfaction and engagement with Strava, especially given that Strava doesn't have the technical wherewithal to add new features, like, ever (my personal suspicion is that all engineers are constantly in a performance code red, trying to get hosting costs down).
I’m glad to hear that, and I genuinely hope it stays that way.

I have been, twice in the last years. Spit on and punched at (the attacker was frail and tweaking, disturbing and menacing but physically unable to hit hard). Other good friends have gotten black eyes and so forth. This is in sf which has a more severe problem (though it is serious in Seattle).

This is to say nothing about day to day issues. Last time my wife ride Bart, a man got on and ranted angrily about “bitches”, though to nobody in general. In this case people just avoid eve contact.

It has gotten very very bad.
Why would anyone working with amounts in the millions or billions care about 0.1 + 0.2 != 0.3? Splitting hairs here I think.
This is largely a myth. It's hard to get exact numbers, but from a recent Seattle Times research project...:

"To sum it up: There are homeless people who migrate — somewhere around 15 to 20 percent of all homeless people — but there aren’t many who migrate far beyond their home state and region. While research hasn’t definitively answered the question of how many homeless people migrate [here from outside Washington State] just to get help, we know that in King County, 3 percent said they did."

Thank you, this helps my understanding.
It's not always as simple as that. What if the problem was that something in a change didn't behave as specified and wound up writing important data in an incorrect but retrievable format? Rolling back might not recognise that data properly and could end up either modifying it further so the true data could no longer be retrieved or causing data loss elsewhere as a consequence.
I don't get this... Poker isn't pure mathematical... it has emotions involved (greed, fear, belief, reading others, manipulations (to fool the opponent)... and may be more... and all of these emotions arises differently for different people based on their time, place, their world view, their background and history...)

Are we now saying that a computer can do this all in simulation? if so, it's a great break through in human history.

Thanks for the questions. We have testing procedures and deploy mechanisms that enable us to ship hundreds of deploys a week safely, including many which touch our infrastructure. For example, we do a fleetwide version rollout in stages with a blue/green deploy for typical changes.

In this case, we identified a specific code path that we believed had a high potential to cause a follow-up incident soon. The course of action was reviewed by several engineers; however we lacked an efficient way to fully validate this change on the order of minutes. We're investing in building tooling to increase robustness in rapid response mechanisms and to help responding engineers understand the potential impact of configuration changes or other remediation efforts they're pushing through an accelerated process.

I think our engineers’ approach was strong here, but our processes could have been better. Our continuing remediation efforts are focused there.
We've got 300k years of fissile material, at current usage rates, which is only a small fraction of our current energy usage. If we magically went to 100% nuclear fission for energy (which is not reasonable for personal transportation, at least), and continued to increase energy consumption per business as usual (developed economies not reducing, and developing economies rapidly catching up to developed usage per capita), then it would not last nearly as long, by 2 orders of magnitude. Also I think that estimate imagines efficient breeder reactors and "complete burning" of the material, and does not take into account our current incredibly wasteful techniques of using 5% of the available energy and burying the rest in an unrecoverable mountain sludge.

I know that a few thousand years still feels like a long time, but with nuclear fission, it is truly the most non-renewable resource, being formed only in stellar explosions. Let's put aside the science fiction of asteroid mining nuclear fuel for now; I think a reasonable argument could be made to not spend nuclear fuel for our primary energy needs. If we have dreams of ever being able to do mass interstellar travel, nuclear material is the only fuel we have so far with reasonable energy density for the speeds and distances involved. (Of course some will say "nuclear fusion" or "light sails", to which I say, we should defer mass consumption of fissile material until we have a reasonable expectation that those methods are viable).

Perhaps, but in the past, like with the comparison feature, Strava has at least had the decency to buy out the third party (before shutting it down and making it premium).

Wanted to echo this.

I've worked in downtown Seattle for the last 10 years, and frequently use the bus system. (caveat: I'm a white male, so generally in less danger, and may be more oblivious):

* I've seen a few brawls (~5) in all that time; generally (all?) swiftly broken up by police

* Haven't experienced weapons (or items used as them), whatsoever

* I've seen (a handful of) needles in that time, but never on busses

* Lots of panhandling, people yelling things, etc.

* 2nd/3rd around Pike/Pike is _definitely_ sketchy, and will make you feel uncomfortable walking around there; but it's also where I work atm: so I frequently am in that area, and haven't encountered much.

This is a solved problem. Open-shoving is a feature of sit-n-gos, so of course people have simulated these and compiled so called "pushbot tables". The parameters are basically pot size and winning probabilities against a random hand.

While this particular bot may not have those programmed in, a more powerful variant eventually will.

I've recently gone through the eGPU enclosure drama after reading an article linked here. I'm using one of the 2019 refreshes of a MacBook Pro, with a Radeon Pro Vega 20. I bought a Radeon RX 5700 XT at launch this week, paired with a Razer Core X, like you've got. (I can go into more detail, but AMD dGPU + eGPU is a ridiculous battle of knowing which obscure config setting to add to drivers to get them to install [Google for EnableFalcon=true]).

rEFInd successfully gets Windows to find the Intel UHD integrated graphics, so that's good. That let me uninstall the Vega 20's drivers and disable it entirely.

Even then, I still don't boot with the enclosure attached - it seems to ignore its presence? Unplugging and plugging it back in triggers Windows to go find all of the hardware, and then I have to wait 30 seconds while things grind to a halt as devices install. I'm eagerly awaiting AMD Navi 10 driver support in OS X, which I suspect will come around since people have found the names in kernel extension strings earlier this year.
How to define a culture is of course a much longer discussion, so I have to defer to my earlier comments. Is the "Smash Bros" or YouTube communities significant enough to be remembered as something special, or is it popular because it is popular?

My point with SoundCloud is that it is a mostly a commercial failure. If youth cultures today was more expressive it would be much more successful. So would make magazine or e-sport venues.

I don't deny that there are cultures on for example YouTube, more the idea that there is something more going on. That we don't understand "beauty blogging", but in the future it will lead to something exciting. No, (or at least mostly not) they will go on to become marketing managers at some company and/or continue to sell Chinese cosmetics. Cosmetics happened last century with people like Estée Lauder.

Asia is a bit of a different story, which I don't know enough about to really comment on. But in the West it is very much that young people have shitty deal and are making the best of it by doing things like playing video games and watching people they can identify with and are popular.

If you think about it a lot of the content is about fitting in, rather than standing out. Which would be the more traditional youth culture.
it's the most non-renewable resource, but it also goes away whether we use it or not.

I've been through the surprise billing stuff multiple times. At this point unless I am unconscious and can not consent, I'm not going to the hospital. I'll bleed out and die on the street if necessary, or spread ebola or whatever. No way am I going there. You go in, they do nothing, then you have $30,000 in bills that arrive in hundreds of stages over the next 24 months.

You're better off borrowing money from the mafia than you are visiting most any emergency room in the US. The mafia has much more straightforward billing transparency, fewer surprises, and is generally more honest.
You not asked to pay anything. But here are the 4 possible outcomes from completing startup school and trying for the $15k:

1. Go through it, apply for core, don't get accepted don't get $15k

2. Go through it, apply for core, don't get accepted to core but get $15k

3. Go through it, apply for core, get accepted to core, enter core, don't get $15k (but get more money, with strings)

4. Go through it, apply for core, get accepted to core, decline core, don't get $15k

Point is if you are accepted in to the core program then clearly you are good enough to get the $15k. But if you decide to NOT enter the core program, they seem to pull that $15k which clearly you are good enough for.

For some startups, they might actually prefer the no strings $15k over the more money and network but giving up equity.

Now of course YC is not obligated to give anyone $15k. But it seems they are pulling the $15k which they consider you at least good enough for, if you don't accept their terms. Which is again their right, though should be clear.
I would argue that this does happen in SF specifically. Being a magnet for people with no leg to stand on (whether because of a lack of resources, prejudice, etc.) is San Francisco's whole thing, and has been since the 60s. They wrote songs about it!

But okay, in the case of Seattle and Vancouver, maybe the arrivals are not from the opposite side of the country, but there still is a constant influx of people from the region. There are huge native communities in both Washington state and British Columbia, and they're falling apart in about the same way as the rust belt. There's no support system in those small towns with enough resources to help the people who are worst-off, so they have to leave and go somewhere else.

(Los Angeles deal) would provide 7% of the city's electricity beginning in 2023 at a cost of 1.997 cents per kilowatt hour (kWh) for the solar power and 1.3 cents per kWh for the battery.

So 3.297 cents per kwh. That's on par with large hydro like Tacoma Power Park. I'm getting 11 cents per kwh for my solar currently in the midwest.

>Teslas are selling like hotcakes.

Because the Tesla sedans combine the driving experience and technological features of a nice German car with the green points of a Prius so white collar professionals buy them in droves (it's the best of both worlds so of course they do).

Basically all the other EVs are competing with economy cars and crossover mom mobiles where the competition is much stiffer and the buyers more frugal. Nobody buying a Tesla is saying "gee, I could buy an Accord and put all that money toward gas" whereas basically every Bolt and Leaf buyer is making that comparison to the Sonic and the Versa.

While you suggest 200 miles or forget it, I suggest that 250 or near it is the absolute requirement for ENTRY level cars. Now a rental fleet, like how they do scooters, could fare well with sub 100 mile cars. Premium cars need to set their bottom level at 300 miles or more.

Remember, all these range numbers are at 100% battery capacity and mild to warm weather. Hence we should not accept less than 300 now. Tesla has been there for years and there is no excuse for any premium brand not doing the same.

As mentioned in another article, I really get the idea the BMW exec recent step down was resulting in part because of that laughable new Mini
This is why the very concept of insurance discounts are problematic. It might sound counter-intuitive to argue against "discounts" as a solution to bringing costs down, but it actually would.

Medical facilities are forced to artificially inflate bills. Insurance then artificially gets a discount back to a sane price. This helps insurance look like they're "doing something" even when they aren't e.g. High Deductible when you pay 100% up to the deductible ("at least I got the insurance rate!").

Out of network also suffers from this. The networks themselves are discount networks and prices for uncovered patients are artificially high.

If you banned insurance discounts and insurance had to pay the same dollar to dollar cash price (without kickbacks/incentives), it would help the uninsured, it would help re-align patient/insurer motivations (i.e. both demanding low cash prices), it would make price transparency actually meaningful, and it would eliminate insurance networks.

But ideas like this, and removing employer provided healthcare (e.g. everyone on an open health insurance exchange) are politically impossible in the US because no politician can get elected for "taking people's employer insurance and taking their discounts." Even if they're the right thing to do to simplify, reduce costs, align goals, and force insurers to compete again.
