The government should become a temporary employer of last resort for workers who have exhausted their unemployment benefits. They could clean up parks, tutor children, paint over graffiti, update public records, provide child care for other workers, etc. Stuff that would be of value to society but which we often can't afford to pay regular government workers to do. This would help to keep unemployed people in the workforce and doing something productive while they retrain for jobs in higher demand.

And we should subsidize vocational training to a greater extent so that students aren't forced to take on financially crippling loans.

I would go with the classic Office suite, but what I would really want in that area is support for open formats from Microsoft. This way anyone can write their fully compatible editor, and we could actually use Libreoffice.

Human Potential is worthless if it is not profitable. A lot of third world countries have jobs programs where they pay one group to dig holes and another group to fill up those holes.

What US currently lacks is the entrepreneurs who would come up with new products and services and then employe the unemployed, old people etc. But given the restrictions on immigration of highly skilled individual this is going to be tough to achieve.
Trump’s Tax Cut Hasn’t Done Anything for Workers
I needed a new bank and thought surely there will be one that offers U2F.. days of searching later, and I still have yet to find one that does. It seems like the vast majority of online banks don't even support any kind of 2FA except email/text. Really really sad.

For regular guys like me, I can't think of any online service more important to protect than my bank account.
Dropbox isn't secure. They have a master key override and have many times already unlocked boxes without the user's permission. Also, they cache your credentials, anyone who gets a hold of the cache file can put it on another machine and get into the box without authenticating.
>so little customers are reporting

Do you mean "so little customers are reporting it to HN" ? Or do you have some data from Uber internal support?
That's always the easy answer, isn't it?

1) Buy a Raspberry Pi and an Arduino
2) Pick a project: telepresence robot, autonomous robot, sous vide machine, thermal camera trigger, etc.
3) Buy minimal pieces for that project: AdaFruit, SparkFun, or various OEM pieces from Amazon, Ali Express, etc. (higher cost = more documentation and fewer lemons)
4) Goto 2)
There are people that use Uber with debit cards, and who don't have a lot of money hanging around in their accounts. An $80-$150 charge (that takes time to ever get refunded) is a big deal for those people.
I don't think you're giving the argument enough credit. Nobody says "I got my iPhone repaired cheaply and now the touch isn't responsive"; they tell their friends "God my iPhone sucks these days".

It's the same reason Kleenex sues when people use their brand for generic products, or Disney forces daycares to take down murals of Mickey, or Burberry burns unsold products. It's a slipper slope away from quality, and while no one thing is a huge deal, the culmination is.

I agree at the end of the day it's about making money, but that's just what being a business is. For certain brands, they want their products to be meticulous. It's not the only way to build a product (see Android), however it is the reason Apple products are so beloved by the people who buy them.
actually, from what I hear, this was the standard for Unix enterprise software distribution between 20 and 40 years ago. this was in large part due to the wide variation between Unixes meaning that one would otherwise have to ship several dozen or even more separate binary packages. today, proprietary software largely targets Windows only, which strongly favors binary-only distribution even for open-source software.
At the time we start using a lot of it (enough to matter), we would also be capable to mine it from comets or moons.
Context: About a year ago when I started on this project, it was literally almost nothing. Now it’s a pretty complex little thing; but it’s still what I would want in a status page — a hackable, free alternative to the expensive solutions other companies are providing. There’s different markets, sure, but for the little guy? This is the kind of thing I’d want to use.

Design feedback, docs feedback, please, I’d love to hear it.

The current master branch is inbetween v2-rc1 and v2-dev2, so feel free to give it a shot while it’s still “brewing.” I’d love any feedback I could get.
Tesla is currently in Junk status (that is, below BBB- rating). But within Junk status, there are degrees. Tesla's current rating is Caa1, well below Baa3, according to a rating in March 2018 earlier this year.

FYI: That puts Tesla's bonds as 6-steps BELOW "junk" status. Tesla is well into junk status and is considered a highly speculative bond.

If Tesla's financials continue to degenerate (and remember: this is a company that was losing 300-million per quarter BEFORE the Model3 ramp-up. Who knows how much "the tent" and all of those extra workers cost??), then Moody's will be forced to lower Tesla's bond rating even lower.

"Default Imminent" is a rating of Caa3. Tesla is literally 2-steps away from "Default imminent". Below Caa3 are the ratings of Ca, and C, when the company is finally entering default officially.

-----------

Remember that Tesla has bonds coming due at the end of 2018 and the beginning of 2019. Tesla needs to pay off those bonds somehow, and so far... it seems unlikely that they can pay it off using profits.

Maybe Tesla will reach profitability in the next few months, but their runway is definitely running out.
> Makes me wonder if you would outperform seeing people in recognizing audio cues, like the tone of the voice to interpret emotion?

By necessity I have to be tuned in to the sounds in my physical environment, to pick up any clues which give me an edge when navigating that space. I'd say it was fairly likely that I do the same when communicating with other people - one of the things that attracts me to people is the sound and tone of their voice. I find it difficult to enjoy acting performances, conference talks, etc when something is off about a person's vocal delivery, however small. Although that probably also has to do with the fact that for much of the day I'm listening to a rapidly-speaking text-to-speech engine.
Alternatively I could pay a taxi driver in cash who has to affirmatively send me a bill in the extremely unlikely event that I puke in his car.

He cannot simply steal money from my bank account and make me fight to get it back.
How would they technically accomplish this? Whenever a camcorder or phone or webcam was used would the hash be transmitted to the manufacturer and registered there? Would the device sign the video signature with some secret key? (similar to that big secret number you're not allowed to show)

Assuming you got it to work sanely, how would you ensure that all manufacturers properly locked down their devices?

Assuming there's a reasonable trust framework and you're able to enforce it... How would you allow legitimate video editing without allowing people to edit video to create misleading images? How would a movie cut between characters and an exploding model in a legitimate and signed manner without allowing someone to splice a politician's speech in with terrorist training videos?

There is a lot wrong with this "Tech can fix it" approach.
There are no download statistics for that though
Second this advice, along with laser-cutting if you have access to a shared workspace with one in your area; take a look, you might be surprised.

Electronics had may as well be lego bricks, these days. If you want to make a robot, you can mostly plug together cheap pre-built modules on breadboards. Outfits like Pololu have great options for things like small-scale motor control and DC/DC conversion, and tiny displays/sensors/etc are ubiquitous.

For most people, getting a PhD is a bad idea. The odds that all that time and effort will pay back is small in most fields. Of course, it depends on the field and what you plan to do with it. I have a PhD in computing, and I'm glad I do. But it is definitely not for everyone.
If a hot attic is making your house hot, then you need additional sealing between the attic and the house, or additional insulation on the floor of your attic. Attic spaces are normally vented so that they are kept at outside temperatures. In the winter, attics are regularly 30 degrees below the inside temperature. A 20 degree difference in the summer shouldn't be a big deal. That said, plenty of people will sell you attic fans or other gizmos to moderate attic temperatures if you don't want to fix the insulation/sealing problems.

Whole house fans do help a lot in pulling cooler outside air into the inhabited spaces.
The Miami Herald article where I think this story broke suggests it's that not every incident gets resolved:

> Despite several email exchanges, Uber never agreed to reimburse her the extra money. But she disputed the charge with her credit card company and got back her $98. Uber then canceled her account.

https://www.miamiherald.com/news/business/article215299675.h...
Check out this article [1] and its accompanying HN post. It references cases where chargebacks were the only option, and one particular story where a rider had two rides back to back commit vomit fraud.

[1]: https://www.miamiherald.com/news/business/article215299675.h...

[2]: https://news.ycombinator.com/item?id=17587952

EDIT: I found a way to re-open my support ticket with uber and linked them the miamiherald article - they then immediately refunded the cleaning fee.
So how long have you been driving?
It's not just vomit fraud. I hired an Uber Black to pick up my mother-in-law once and got charged $60 in "damages" from the driver claiming she damaged the interior... the woman is not even 90 pounds and had recently recovered from hip replacement surgery. My wife asked her about it and she was shocked... said the ride was very smooth and the driver was friendly. She's not the sort of person to make anything like that up or omit it out of embarrassment.
The economy and the education system are out of sync. We are turning out a TON of degrees for a few jobs and expecting people to be able to just succeed based on a 4 year degree program. All the while the economy does expect a 4 year degree for some jobs that really shouldn't. So you're expected to waste money on a degree you don't need to work a job that won't help you pay back your degree because they aren't paying you what you need to pay off that debt.

I don't have a solution. I just see that I know plenty of people who have GREAT degrees, are very intelligent and are working in a field where their success is more defined by who they are then how they were educated. I think whatever solution we do have, needs to take a look at both the economy as well as the education system and how we prepare our young for a life in the workforce. Because at the end of the day that's what we're doing, we're educating our young to be able to step into our economy and profit.

Again, I don't know the solution. Regulate the number of graduates within a certain degree field? Regulate jobs so that we force jobs to accomodate the degrees? Unionize alternate jobs so working at walmart / factories becomes profitable again? I don't know I just worry about what my children will do when they enter the economy and how will they stay in the middle class.
From the original article this one is referencing -

> “I immediately contacted Uber through the app. I told them that I was alone, sober, that I was not carrying any drinks and that it was impossible for me to have caused that damage,” she said. “But every new email from Uber came from a different representative and always favored the driver.”

> Despite several email exchanges, Uber never agreed to reimburse her the extra money. But she disputed the charge with her credit card company and got back her $98. Uber then canceled her account.

You're right, but the problem is it it only takes a very small number of excessively greedy and power-hungry people to make the world worse for everyone.

I take pictures, insist on a walk-around, and insist the employee on the walk-around with me notes all observed defects.

Sometimes, they'll say "don't worry about it". I politely, hopefully somewhat adroitly and politically, insist.

In many situations, e.g. storm damage, I've taken to taking a bunch of pictures -- maybe also a video, in which all the observations "hang together" and have contemporary commentary.

I may never need to use this, but digital memory's cheap, these days, and it also saves me from worry about trying to recall details at a later date.

Just yesterday, I was looking in on an older artist friend who has a combination of care-givers and an handyman through the house on a daily basis. Part of one of her heavier, wall-mounted ceramics had crashed to the floor, with the top end leaning against the dining room table.

What happened? I'm not sure (the friend is confused, at times). But I grabbed my phone and took some pictures. The handyman probably has it cleaned up by now. But if something needs to be done -- even just an insurance claim, depending on the details of their insurance that I don't currently know -- I can supply the pictures.

On the other hand, I feel a bit at times like I'm expressing/demonstrating paranoia. And the whole "surveillance society" thing. I try to limit this to immediately relevant subjects/events, in my own life. Not "watching the neighbors".
I understand what you're saying, but the fact is that, at least the customers in the article, all did eventually get a refund. Which makes it a "non-story" to me, personally. This could happen with any company. Company X accidentally charges you more, you dispute it, and you get your money back. It sucks, yeah, but it's not a big enough Uber specific problem to warrant a story like this trying to make it a bigger deal than it is.
Fair enough, and it's easy to test :)

I made a non-iterative DFS, but hardcoded the maximum depth to the optimal solution. On a trivial puzzle that should take <1ms, it takes 6 seconds. The BFS visits 303 states, the DFS 9M (but only 237 unique ones). This is with deduping the states on the path. If we allow the same state on the path multiple times, it'd be 12s, 50M visited states, 239 unique states. This is with a random visiting order, it'd be a bit worse with a static visiting order.

This is obviously not fully optimized code (whee, std::unordered_set). But fixing that won't help when we're off by 3-4 orders of magnitude. I think the shape of the search graph of this game just isn't well suited to any form of DFS, there are far too many alternate paths to each state.
Their pricing is a bit extreme, especially when it comes to counting users. Its the biggest reason why we haven't paid for any tier. I'd love to pay for at least the Starter, but we have 20 external developers (but only 2 active ones) and 6 internal developers (all active). It'd be nice if there were different tiers between the users (single repo users are cheaper than multiple repo users, and the admin users doesn't count).

There a lot of great points on this thread. We need more distinction between contextual and non-contextual advice. If one is ‘at the board’ working through a problem — then a hint or solution, moves the problem forward. On the other hand, if one is just ‘leisurely browsing advice listicles’ without being at the board, facing the problem, then most likely you are just ingesting dopamine-flavored noise.

Advice without context from anyone — whether it is PG, pmarca or Richard Feynman or {_your_fav_successful_survivor_} - would be useless, unless you are working/thinking about the problem that they are giving solutions for. Help only works if you are looking for something. Also sometimes it is good to just enjoy problem-solving and figuring things out. We are too quick to look for advice — and I get why: because no one wants to “reinvent the wheel”; There are too many standardized administrative things with startups that can be just solved by looking up advice; no problem with that; but sometimes it is worth struggling through a problem even though geniuses like PG and pmarca can give a solution quickly.

Abundant capital has led to too many VCs with too many blog posts looking to differentiate with their advice, under the guise of differentiation, content marketing, “proprietary deal flow” etc. If content is “bait” then you are at the bad end of the line.

When faced with a problem, find someone who can help — All other times, just do the work and enjoy problems :-)

(Did I just give advice? Can’t tell)
This is basically my thinking :/
Lots of things are profitable but never absurdly and increasingly profitable, which is the trap we are now in.

There’s no credit given for having a tidy business with steady profit. Instead you have to have “growth” and other this-quarter-must-be-better-than-last-quarter-or-else crap that “investors” want.

Good question! His story "The Martian Way" addresses this. I don't really want to spoil it from you, but basically: where you'd expect.

> Surely they weren't storing it as H20 on the ship?

Why not? It's stable, it's useful for other reasons, and when you've got free energy and easy propulsion, there's no reason not to. (There probably would be some issues with sloshing, actually, but he didn't get into it. Asimov wrote a lot of stories that could be considered Hard Science, but I don't think he'd consider himself an engineer.)
Or what happened to me, where I was in a vegas cab (before Uber existed), but there was some confusion (perhaps with the next passenger?) and I was charged ~$200. Disputing it, especially ~10 years ago was a nightmare. Uber has a lot of issues, but I do not miss cabs.
> Only out of spite

Not really, it's basic diplomacy. Spain has interests, investments, and assets in all regions. Catalan nationalists wanted to leave without defining a process of retribution at all, but defining very well that they wanted Catalans to keep Spanish nationality (and related benefits) on top of Catalan one. So they could suck the tit of two states, in an unilateral fashion. It was overall a dick move (Naive? Delusional? Exercise for the reader), and being a grown up you assume the consequences, you aggravate a party then don't complain they get the long end of the stick when they have the upper hand.

It's even dumber than Brexit if you think about it. Do you also think EU stance on Brexit is also "out of spite"?
Teacher friends of mine talk to me about how their job is next to impossible. The curriculum in the schools is basically perpetually 12 years behind, students today are just now being taught stuff that the market is now responding to but the fundamentals that are needed for those skills should have been introduced years prior.

Educators are effectively trying to project 12 years out and try and guess what the market will demand so that they can provide the minimum skills necessary to provide a modicum of middle-class life.

Supposedly the landscape is beautiful in the winter, thanks to the snow. Personally I chose to see it in the summer, though, so I can pack fewer clothes.
I doubt you are right. Many people make product buying decisions based on What their friends and peers own.

Apple does allow 3rd parties into their ecosystem (app developers), but they lock that process down to specifically retain control of the experience that customers have

You may not want that, and your company may not make the same choice, it Apple’s approach works pretty well for them.
A similar issue happened to us recently.

We gave a driver a 3-star rating for being a particularly bad driver (driving aggressively, cursing at other drivers etc).

Later that day, my girlfriend (whose account we had used for the ride) got a warning/strike on her Uber account because a driver had reported her for "making racist remarks in his vehicle and making his driving experience uncomfortable".

For the record we had barely spoken a word in the car during the ride, as we were both quite tired. Our driver spoke more than we did and it was mostly obscene complaints about other drivers and cars on the road.

We concluded it had to be the same driver, as we hadn't taken another Uber in a few days, so it was basically retaliation.

The email said that if enough of these reports are received she would be removed from the platform and her account would be shut down. There didn't seem to be any recourse or appeals process noted in the email..

So I wonder if this is a sneaky way for drivers to punish passengers for bad ratings..

How do you prove/disprove this kind of accusation?
This would only hinder amateurs. Pros will just intercept the camera's own sensors. (A simple version of which can be done by amateurs: take a certified video of an uncertified video.) Maybe you could build GPS into the signature, which could help (I'm not sure how hard it would be to feed a camera fake GPS). But even if all these tech solutions work 100% perfectly, all you've done is weeded out laymen. The REAL powers (such as governments or multinational corporations) will just make backdoor deals with certificate authorities.
Yes, this case kind of proves that they implemented disk encryption correctly :) If MBP weren't such overpriced garbage recently (fckuing Touchbar, fcuking AMD GPUs, fcuking overheating, throttling CPUs) this could convince me to buy one.

The linked solver doesn't use iterative deepening, and it saves all states that the DFS solver encounters (negating the advantage of using DFS).

I think IDDFS might work really well here, even without a good heuristic. It's worth trying, at the very least.
