From the top of my head, I can list at least four reasons to actually use anything else:

- Not distributable

- Poor resiliency

- Hard to upgrade

- Schemas remains at postgres core

Every solution to address any of these points in PG are hacks (bucardo, londist, slony, pgbouncer, things relying on triggers or proxies). Quite honestly, PG contributors are doing an impressive job. PG is arguably the best relational database in the market as of today and still improving very fast. However it's also one of the most (if not the most) bloated. And despite all these features nobody needs and after all these years, it's still lacking some very basic yet essential items anyone would ask for in any modern application. It feels like things haven't changed that much since the 90's. DBAs have to hack around things and root issues never gets addressed. Implementing JIT optimizations looks like fun. It will undoubtedly improve some queries by 2x, 4x or even 10x, but it won't be a game changer anyways. It'll just increase the postgres bloat and the overall complexity of the system. Meanwhile, we'll still be lacking essential things that would make PG suitable for pretty much any use-case.
Not accurate. Theranos's investors, board and outside stakeholders where by design people with no medical or related experience.
I confess I gained a ton of respect for Klik & Klack was when they gave the advice to not teach kids on a stick shift.

This is akin to teaching a kid to ride a 21 speed bike. They can probably get up to that rather quickly, all told, but just learning the basics of balance and pedaling will already be difficult enough.

Similarly, just learning the basics of the car will already be tough. Why add to it? Why not take away power steering? Because it would make it harder.
SV in general seems to be operating (for the most part) in "make X regardless of privacy/security, to save time/effort on Y".
To account for some interviewers being sadist in general, may be companies can implement a per interviewer rejection quota. For example, if you interview 10 candidates at max you can reject 7 candidates. You have to yes to 3 candidates or be removed from the interviewing committee. This will ensure that just one bitter person is not preventing good candidates from clearing the interview process.
This doesn’t seem like a serious story. Google helped some campaigns that non-partisanly ask people to participate in elections? So what?
Ask HN: Seeking beta testers for machine learning models to API service
I'm building a Saas that helps create an API for machine learning models: https://orchestrahq.com - and looking for beta testers to give the platform a go.

This service will be most useful for data science teams who want to manage all their models that go into production. It'll also make integrating with web/mobile applications easier as you just need to hand off a URL to your development team while you continue to improve the model.

Many features on the roadmap including continuous integration, testing, etc. but I'm also happy to have a chat about any use cases you might have.

Currently, it's supporting Python 3 but am looking to support more languages in the future.

If you feel you can help, please send me a note via "teren AT orchestrahq.com" and I'll send you an invite link.

If you're interested in using it for your company or startup, I'm happy to provide discounts and talk through how we can customize it for you. If you're a data science consultant, happy to discuss a potential revenue sharing agreement. And if you're just interested in helping me give it a whirl, happy to buy you a coffee.

Thanks!

Same. I bought a Tacoma a couple of years ago, and while there was technically a manual option available, nobody actually had one, or could tell me when I could get one.
> Second off, the number of applications rejected for every hire is staggering, simply because of how many people apply. These numbers are fantasy, but imagine if you had to choose one person out of a hundred applicants, and you actually had the means to interview every single one. You're going to pay this person a quarter of a million dollars a year and aim to keep them for half a decade or more. The economically rational thing to do is be picky as all hell, and this is exactly how Google and friends do it.

That's a good point. It's hard to ignore just how many applicants you filter out in the hiring process. However, Google and Facebook are exceptions in terms of having a non-differentiated hiring test. They are very big exceptions, but still exceptions. They have a standard interview bar and matching with teams comes later. On the other hand, Microsoft, Apple, Amazon, Samsung, Adobe, etc. all hire for specific roles.

I think the way to reconcile the nuance I was getting at with "matching problem" is this: "picky as all hell" must still be fair and backed up by a clear idea of why your requirements are as tough as they are. When you see yourself as a gatekeeper you're more likely to lose sight of that.
Engine breaking just means slowing down by letting the foot off the gas. You aren't really slowing down that quickly. Someone has to really not be paying attention to miss it. It would be the equivalent of someone merging.
I would never vote for a candidate I didn't believe in. If you want to remove qualified engineers from hiring decisions based on arbitrary metrics, I'd probably be looking for another job on the side.
For practical (mature, usable in production) implementations i'd recommend:

Speaking as someone who has owned a number of sports cars with manual transmissions, I can tell you why I finally made the switch to automatic:

Adaptive cruise control in stop and go traffic.

I used to have to deal with a six-speed manual transmission in stop and go traffic for an hour every day, and it was pure torture. I mean, sure, it was fun for a weekend drive in the mountains, but it sucked the rest of the time.

Oh, and as a side note, my new car with an automatic transmission and a 400+ HP engine accelerates from zero to 60 faster and smoother than any one of my previous cars. I will never go back! And I have paddle shifters, if I ever want to manually control the gears.
The title seems misleading. There doesn't appear to be any new technology here, just a funding round announcement.

In a press release, the company listed a bunch of advantages that they claim their technology has over current batteries

The aversion to link to source documents really hurts the credibility of publications like this. It forces me to try to find the "press release" on my own. Ok, here it goes.

I went to the Solid Power press release page and found nothing about a breakthrough - indeed nothing since last June, and then nothing of technical note:

https://www.solidpower.com/en/news/press-releases/

The blog has one more recent entry, but it's just a trade show event:

https://www.solidpower.com/en/news/

Oddly, neither page mentions the recent funding round.
I used to think the same way. But, Mercedes have auto boxes absolutely nailed - and I say this as a car enthusiast from the UK, where most cars are still manual, and almost every car I've owned has been manual. My last car was an E350, and the transmission was amazingly good - every time I would have shifted, the car did it for me. I've a BMW now, and the gearbox is good... but it doesn't quite have the 6th sense that Mercedes have figured out.
> And despite all these features nobody needs

Please do speak for yourself.
In summary, the reason (from a spending perspective) presumably non-profit colleges are so expensive in the US is that US colleges spends 2x/student as much on staff and faculty as many OECD counterparts.

College faculty, staff, and administrators form a large constituency that will be campaigning to keep spending (private, public, or otherwise) up, which campaigners for lower higher-educational spending will need to keep in mind.
That is exactly incorrect - and exactly what your parent was talking about. It is impossible to turn information into energy. Because it takes more energy to gain and use the information than you can extract from the system. We will never have such batteries if our current understanding of physics is correct.
Is that a hard rule though? Is it possible for a company to stay at 3 and make a profit? Is it pressure from investors that pushes them on to step 4, or the forces of competition?
Thanks, title changed from "JSON draft 07 supports if/then/else" which would have been a shocking development.

I hope that by talking about what it means to build well when trying to serve everybody, we can show businesses how short they’re falling of the mark — and why those common root-causes in JS-centric development are so toxic.

I guess I hope that you're successful, but one would assume that if today's Javascript climate was so toxic and having a tangible effect on your average user (not just the Hacker News user), then...there would already be swarms of clever individuals capitalizing greatly on this apparently obvious state of the web.
> If my starter goes out, I won't be stranded, I can just do a push start! Heck even if your battery is dead you can normally still push start.

Most modern-ish cars really don't like this, regardless of transmission.
The issue with fakes (or deceivingly advertised) items on Amazon is something that seems to have gotten worse in the past year, and is a big reason I'm not renewing my Prime either.

In one case I ordered a name-brand transmission rebuild kit but received a knock-off with a similar name. Unfortunately I didn't notice the difference before I dropped off the kit with the friend who was rebuilding the trans for me. He kept complaining about parts not in the kit, and I kept being mystified because I (thought I) bought the top of the line kit, there was no more-comprehensive one to buy? It wasn't until the next time I could get out to his house that I realized we'd been scammed; by then he'd already used part of the kit so I just bought another kit to get the missing parts.

The second occurrence was I ordered a normally $30 set of 4 spark plugs for $20, and what I received was 1 spark plug - obviously the scam is break up the $30 pack and sell for 4x$20. I got a refund on this one and got to keep the plug, but it delayed an important engine repair and also left me with a dilemma as to how important it was that they match - I ended up using the one expensive plug and three mid-range plugs (because I would have just chosen 4 cheaper plugs in the first place if I'd known).
i would like to see stats on that. in my experience people are very hesitant to pay even if they recognize they derive value from your service. it's just not the "thing that everyone does"
That can be easily avoided though. 1) Do it outside or in a well ventilated area. 2) Wear a mask. Extra precaution) Change clothes when done.

To that point, I'm not trying to claim it is insurmountably dangerous. It is more dangerous that just using the brakes, though.

That can happen with a automatic transmission as well. You should not rely on the "brake lights" to realize that the car in front of you is slowing down or stopped.

> In Germany the private insurance is actually cheaper than the public one

Well, the public insurance is a percentage of your income. The private one is based on many opaque factors. Private cheaper than public would be a more than a stretch without appropriate qualifiers.
I've wondered how this is issue is addressed in EVs that offer one-pedal driving. Do they show the brake lights when deceleration exceeds a certain rate?

Similarly, when I'm braking very lightly in my plugin-in hybrid in order to charge the battery all the way down a long hill, I wish there were a way to not have the brake lights activated the whole time. It's only barely slowing me down, and I've driven other cars that decelerated more going down the same hill just due to wind drag and rolling resistance.
My previous car, a 2008 Subaru WRX, in manual had cruise control; while it wasn't adaptive, it was the most important thing I will consider in any other manual transmission going forward. Stop-and-go traffic to my previous job made driving a chore and weekends weren't enough. I miss having that kind of control over the car, but the automatic Mazda3 I replaced it with has made that traffic an afterthought.
Two important qualitative differences from Theranos:

- Spinoff from battery research program at a University, not a bachelor degree dropout

- Investors are technical

So no, Theranos did not have any "serious" investors if using the definition of "serious" as those that are technically competent/know how to evaluate the technology. It's possible of course that it's all still a scam like Theranos, but more likely if this doesn't pan out it's going to be some limitation with the underlying tech, market adoption, competence running the company rather than outright fraud.
Agreed.

In particular, I agree with both points that "you should signal folks behind you that you are slowing down" and "you should pay attention to how fast the car in front of you is going." Neither point diminishes the other.
On hikes I always think there should be freeze dried water.
You just use the handbrake as necessary. I mean, it's not necessarily simple. But very much possible.

Actually come to think of it, I've made some open source apps that people asked if they could donate to, because they were so excited by the possibilities my apps created, and by the convenience they now had because of them. I created a Patreon for this but have yet to link to it anywhere because I keep sinking into cynicism from all the ways I haven't been able to make money. But that's not the attitude I had when I created my window managers. Software that focuses on user-happiness can make money through donations. Just, probably not a full-time income.

EDIT: Apparently that's not true, you can make a full time income. Godot makes $10k per month in donations. And a month ago it was $8k. Wow.
Not really; it's pretty much impossible to stop suddenly via engine braking alone in a stick shift without forcing the transmission into a much lower gear (fourth to second or first, for example) and engaging the clutch, which will damage the drivetrain if done more than a few times. Engine braking, if done correctly, is a gradual slowdown with the ability to immediately accelerate again, all without wearing on your brakes, and once it's learned it becomes a natural part of driving a manual. If someone is following you close enough to hit you while you gradually slow down, tail lights or not, that's their fault for tailgating.

That said, engine braking isn't appropriate in all situations; I personally wouldn't do it in heavy stop-and-go traffic, but for highway and around-town driving it's perfectly safe. I definitely wouldn't do it with a tailgater behind me, just out of common sense.
Tesla Gigafactory to achieve $100/kWh cell cost in 2018, output surpasses China
One thing that sticks out to me is that you say you were trying to get the gear you wanted - having driven various automatics, that's never really been what I'd care about. I just aim for a speed. Older automatics you end up noticing gearing sometimes, but just incidentally, and on CVTs, which is what I have now, you really don't care about 'gears' (which don't exist for CVTs anyway).

That said, I have driven automatics with some weird gearing where specific hills mean you'd oscillate around the desired speed. There, you do end up caring, unfortunately. That said, that's the kind of situation where the manual mode on newer stuff comes in, and on older stuff, you'd have a few gearing sets (Drive/Low/3, on a grand caravan I used to drive. Never did figure out what 3 was good for...)

Tell HN: Violent incitement on Twitter
Context: South Africa has for the last 20 years, had very weak immigration controls. This has resulted in large numbers of foreigners from other parts of Africa as well as Pakistan, India, China and Bangladesh moving is to the country and opening small businesses in poorer areas. This has led to resentment and deadly xenophobic violence, most notably in 2008. South African law enforcement is incapable, and frankly incompetent, to deal with this. These foreigners are apparently referred to as “Pakistanis” by uneducated people despite most seemingly originating from East Africa.

South Africa has been the subject of social media destabilisation efforts by the likes of disgraced UK PR firm Bell Pottinger.

Some South African mobile networks provide free Twitter access, which means that the platform has a disproportionate level of penetration into a population that is uneducated and unable to navigate the complexities of social media, and has a track record of being easily incited.

Stories like this one against what is a “Pakistani” (actually an East African):
https://twitter.com/da_ernzo/status/1039089041357062144 get thousands of likes and retweets. There are violent threats in that thread, some probably being put there by bots.

It’s a matter of time before people get killed, if it hasn’t happened already. It happened in 1994 in Rwanda because of radio, and people have been killed in India because of social media rumours.

I know that Hacker News is an unofficial support channel for Silicon Valley. This is a plea for Twitter to please allocate more humans to rapidly deal with this stuff in South Africa. Closing third-world accounts that incite violence won’t hurt your bottom line. Your ML algorithms are too slow to stop this kind of thing. Otherwise people WILL die.
I find people who learned how to drive manual to be better drivers - they tend to think ahead which is understandable. One does not really want to shift just to jump ahead of one car to see that there's nowhere to go. It is too bad that fewer and fewer people have this skill.
I'm curious why you care about the brake lights being on if you are actually braking. Even only slightly.

Though, to directly answer your question, I don't know how cars that only have a single pedal work with this. Embarrassingly, I didn't realize those existed, so would be as interested as you in the answer.
"nobody needs" is to take in the unix philosophy sense here. If you take it first degree, you're part of the reason why PG has been missing these essential points for so long (IMHO). In comparison to the items I've listed, those features are nice to have but definitely not used by the majority of users. And I do use these advanced features (nobody needs) in PostgreSQL. I use them extensively and really love them. It's just that I could workaround them easily and properly. That's just not the case for the things I've listed.
> you don't expect them to keep a bunch of containers loaded with your dependencies ready to serve requests

I think you would expect them to at least use swap for density and always keep one extra instance running and ready to serve requests. It's not like people generate functions on the fly, so it shouldn't even cost anything extra. Swap will help with unnecessary things kept in memory.
I agree, but you actually can slow down relatively quickly at stop-and-go speeds if you have some RPM on a big V8 and you take your foot off the gas. Certainly I try to remember that, because I tend to avoid using the brake pedal except when strictly necessary. I've seen some people behind me act kinda surprised that I can slow down without activating the lights. Yes they should be watching my car, not my lights, but this is the real world.
Doesn't seem like it.

> Initially, Singapore let hospitals compete more, believing that the free market would bring down costs. But when hospitals competed, they did so by buying new technology, offering expensive services, paying more for doctors, decreasing services to lower-class wards, and focusing more on A-class wards. This led to increased spending.
Tucker Carlson is still shocked to learn that nonwhites are allowed to vote in the US. Things just haven’t been the same since Jim Crow retired.
Engine braking is a pretty gradual deceleration - if the car behind you doesn't notice that you're slowing down in the ~30 seconds it takes to close a safe distance with a car that's gradually slowing down, you got bigger problems. For that matter, automatics do it too. Take your foot off the gas in an automatic and wind/rolling resistance will eventually slow you down too.

I find that the fuel economy savings from engine breaking are largely a matter of incentives. You can drive the same way in an automatic, and you will get nearly the same fuel economy savings. You're just not incentivized to do so, since the break/gas dance is much easier in an automatic and you don't have the cognitive feedback of needing to shift gears each time you accelerate or decelerate.
Agreed. I learned on an automatic at 15 and then "upgraded" on my own to a manual in my 20s because I wanted one. Adding in a manual transmission makes driving non-trivially harder. Just learning the basics of not hitting things, merging, keeping an eye out for traffic, signaling, etc., is hard enough for beginners.
