the idea that uber loses money on rides because of "VC" needs to die. uber is not VC funded anymore and hasn't been for a long time now.

uber loses money on every ride because uber loses money overall because it spends a lot of money on other projects, not because the marginal cost/benefit of each ride is negative.
Hey, it's the guy who called Tesla a "good corporate citizen" just a few months ago. Let's add: breaking stay-at-home orders, called the US government "fascist" while praising China, hired people to hack the personal computers of a whistleblower (as reported in a recent deposition filing), extorted the California government, and forced their workers back to the factory floor amid the pandemic to the list of "good" things.
No, they are the ones driving it. And now they will be out of their job.
I work daily in a codebase with 20M lines and RubyMine can still search near-instantly compared to say VS Code. One thing that's still true is that there are sometimes long pauses, presumably garbage collection, or I suspect more likely bugs as changing window/input focus can sometimes snap out of it.
Don't understand why this didn't get more hype. This is amazing. Well done
Sounds like OO to you is all about encapsulation. I think that's fine, but lots of paradigms support encapsulation. It's absolutely pervasive in FP and DO programs, for example (even C supports opaque pointers). Do we say any language with encapsulation is also object-oriented?

Or is OO encapsulation + inheritance? One problem is that the OOP community seems split about whether or not inheritance is a defining feature of OOP. And since encapsulation isn't a defining feature, surely it's inheritance. Unfortunately, there's no clear consensus, so OO as a term is not very useful.

> The philosophical difference with OO might be that OO uses the compiler to enforce that data is only accessed in approved ways. This is a logical extension of static typing. (Of course, for non-static-typed OO languages, it doesn't happen that way. They enforce it at runtime.)

This is an interesting distinction; ironically C compilers support encapsulation via opaque pointers while Python doesn't enforce encapsulation even at runtime (it's all based on convention--"consenting adults" and all that).

> I didn't say that inheritance hierarchies are bad. They're great... if you've got entities that are actually in a hierarchy.

I think there are cases where inheritance doesn't overtly bite you, but I've never seen a case where inheritance is actually cleaner than composition (with the exception that in many languages, inheritance is the only way to automatically delegate--they lack something like Go's struct embedding). Specifically in your Statement example, you could have gotten your polymorphism from a Statement interface instead of a base class.

Inheritance seems like just a particular subset of composition and polymorphism--there are cases for which it is appropriate, but why does it need to exist at all when you can get the same benefits from composing the constituent components (components being polymorphism and composition via interfaces/first-class-functions and object-/functional-composition, respectively)? It feels like having an add4() function--it's not always bad (sometimes you really need to add 4 to another number), but the more general 2-argument add() function works just as well in the cases where add4() doesn't overtly bite you, and it's much less likely to be abused.
> so you might end up with companies losing money to give people things that they don’t want and driving out the things they do want.

I don’t see it this way. Obviously people want it, the problem is they can’t afford it. Everyone wants their own driver, dog walker, chef, house cleaner, save the earth mattress, whatever else, but they can’t afford it.

Although you can get a lot of that stuff in countries with poorer populations and fewer government safety nets.
LOL @ warhammer. I understand the sentiment, and the reason one might prepare one's daughter. I think that is healthy, in preparing them to deal life. But that doesn't mean it should be accepted, tacitly or otherwise.

>I think my experience is just the opposite, but about 95% of my social circle is manwhores

I get ya. Been there. I just feel we need to move from is implied consent. Couchsurfing and implying consent means the women either puts up with it (leveraged consent is ugly) or ends up on the streets. That is not good, and can be avoided if people are just more forward, even tactfully so. I suspect that this leverage is exactly why they choose the couchsurfing, and that mixed without transparency is ... eeesh, imo.

I'm not apart of the "tinder" generation per se, but I think the (at times gross) honesty is largely positive. People who scoff at the screen shots of people openly discussing sex are being prudish and don't understand that merely being transparent is a net positive.
Well, you're right about one thing: that sure is a simple method.

Useful? No. Effective? No. Meaningful? No. But definitely simple.
You can't fool me, I know this was just an excuse to improve your FPS aim!

Jokes aside, really good read. I had similar goals of cutting out sleep when I was younger. I'm curious what the authors mood was throughout the experiment. That's the main thing I've noticed when not getting enough sleep. My output may be good, I may feel engaged, but every second of the day is torture.
I don't think this is accurate. I've worked several contracts in my life, often working alongside the company's FTE developers. In every situation, we were fully integrated into the team, with the same level of access, etc. We fully participating in meetings and planning. The contracts were several months. (one as long as 18 months; it only was cut short due to 9/11) I will admit these weren't strictly software companies, and in every one of these roles, I was a w2 employee of a staffing company, not a 1099. However, I was at least as effective as their regular team members; probably more so because I could be released far more easily.

I'm a little more nuanced in my analysis than the GP, but yes, I do feel that way in some degree about all the companies you mention, and how the employees have some incremental responsibility for the bad those companies do.

Offered rents in Vancouver have dropped 15% since the pandemic took hold and AirBnB became a dead business for a bunch of mini-hoteliers. If you helped build that software, then I hold you a little bit responsible for the crisis in affordable housing we've been struggling with, that AirBnB has contributed to.

If you work at Facebook, then I hold you a little bit responsible for the consequences of the 2016 U.S. election and Donald Trump's presidency.

Your share of the responsibility is likely tiny, and I'm not going act like you're a mass murderer. But at the end of the day you were part of the machine that left a trail of damage in its wake, and I won't ignore that just because you were merely a cog.
>consumers are choosing to use Google despite the privacy-oriented preferences here on HN.

I'm not sure I'd agree with the word "despite". I still think the majority of the non-tech world is still oblivious to the privacy implications of G,FB,etc. Sure, I'm sure there's a percentage of people that have made the decision they don't care and are fine with it, but there are definitely don't know/understand.

The US has a pretty well defined notion of "protected class" since at least 1964. Like all of law, there are ambiguities and edge cases that have not been fully enumerated or explored in case law. You're acting like this is a huge nebulous concept, and displaying confusion about minorities.

People often say "minorities" when they mean "protected class." Women are not a minority, but they're a protected class. Billionaires are a minority, but they are not a protected class. Who decides what constitutes a protected class? Case law. When a suitable number of cases demonstrate harm on the basis of membership in a class, then that class may be considered for inclusion in the definition.

The definition of hate speech in Canada is quite narrow, and hinges on the definition of protected class. Progress is slow and methodical, and not the slippery slope thay you drscribe.
Huge fan of your gpt2-simple library, which I used to train a satirical news generator in a Colab notebook: https://colab.research.google.com/drive/1buF7Tju3DkZeL-EV4Ft...

> Generates text faster than gpt-2-simple and with better memory efficiency! (even from the 1.5B GPT-2 model!)

This is exciting news. One of very few drawbacks of gpt2-simple is the inability to fine-tune a model of more than ~355M parameters. Do these memory management improvements make it possible to fine-tune a larger one?
Ha, I had the same experience on a date with my brand new tiBook in 2001 .. wouldn't play the DVD .. but VLC, which had been released around the same time as the tiBook, did though!

In my case, we'd carried my tiBook up to the lawn on the front of the Hollyhock house in LA (Frank Lloyd Wright house), and watched Blade Runner on a blanket on the grass
with the house in the background, as that glorious California sun set in the distance. My date was most impressed that we were having an outside movie date in that way ... it was pretty neat to have such freedom on a picnic date. (She wasn't as impressed when I checked my email over the Ricochet modem I had though, even though it was frickin' awesome at the time..)

Been a VLC paid subscriber for almost 20 years now, as a consequence.

Does PeerTube have an answer to the discoverability problem yet? That's one thing I've noticed in the past.

It works if you have a specific URL to click on for a video, but if I just want to "find" a video, that will be relatively difficult.
The guzey_arena_0 test could be biased by his skill level improving over time by playing it regularly, though if he was an avid FPS gamer prior to the guzey_arena_0 tests, the asymptotic growth of skill had probably leveled off in time. I didn't see this addressed in the paper outside of this section:

"I will give myself a sleep opportunity of 8 hours (23:30-07:30). I will practice the tasks I’m going to use in order to mitigate the most extreme practice effects during the experiment. I will perform all tasks as follows:

Aimgod guzey_arena_0 at 12:30-12:50, 15:30-15:50, 18:30-18:50 and 21:30-21:50 (I also played about 2 hours of guzey_arena_0 on 2020-03-31 and 2020-04-01 while designing the experiment)"

That might not have been enough to blunt the practice effect.

Still I think it's valid data - might have been better if he played guzey_arena_0 for a period beforehand on normal sleep until his improvements leveled off.

Agreed, I had been using JuiceSSH[1] but then it seemed to no longer be supported (though I see it just got an update) so I then switched to Termux to be able to ssh from my phone (which is running Android 10, I guess I haven't run into these problems since I don't generally do much with the local filesystem).

In my case I'd also lose about 98% of my contacts, who're non-technical and don't care enough about some very abstract threats to abandon their social network or use yet another messenger app in parallel.
Also, since it's not well-known here, people tend to be very suspicious of it at first, because it's not known to be super safe like Whatsapp.
You can't break the site guidelines like that. We've had to ask you about this many times before. Your comment would be fine without the first sentence. (No, I'm not defending the opposite side of the argument. I'm defending HN's guidelines, which please follow.)

Microsoft had speech recognition since WinXP. And also Dragon Naturally Speaking. Both needed a couple of hours of training, but worked really well, completely offline, it was amazing for me at the time. It did have a very high processor usage, but that was on freaking single core Athlon and Pentium. I'm not even a native English speaker, though dare I say my English is on par with any American.

Even when the numbers aren't arbitrage it's appalling. Friends of mine will regularly order $8 of food for $20 delivered. And these companies still post massive losses after all that markup.

Meanwhile Walmart abandoned their RFID automatic checkout system because RFID tags cost more than the markup of bananas, their most commonly sold item.
Don't use their services ?
It's not illegal. But the casino is private property, and if you don't follow their instructions to stop counting, and ask you to leave, now it's trespass.
It's both.

The ymmv is always big with electronics. I.e. my second last graphics card (gtx970) died within 2 yrs. But the aging effect from running 24/7 under high load is very real as well.

The high temperatures of permanently running on full power just wears it down
I'd rather not give away too much personally identifying information, but I recently joined a company in the media production software/hardware space that has been around for a couple of decades but still has a small-ish "startup-y" vibe. The culture is great, everyone is friendly and the work-life balance seems amazing so far (I have a family, so that was important to me). I'm working on tools that help creative amateurs and professionals do great work. It's not curing cancer or solving world hunger but I can go home happy with how I'm using my skills.

Before that, I was in several small companies in ad-tech. I didn't feel great about the work, but the cultures were also laid back and family-friendly. Non-FAANG companies with great culture are out there; please don't settle :)

Edit: if you're looking for the highest-paying jobs, you are correct in that often times, looking at a basket of job offers, FAANGs will offer the highest comp levels. If getting the highest possible compensation is your only criteria I think you are going to have a much tougher time finding compelling non-FAANG offers (though conversations with former colleagues lead me to believe that high-comp non-FAANG offers are indeed out there). I've chosen to prioritize my own happiness and time with my family over high compensation, and I can get by on the lesser (but still high in relative terms) comp offered by smaller firms.

Twitter: “Replace the term 'user' with 'owner'?“
I think so. As of 2019, 4 of the 7 SI base units were redefined by setting exact numerical values for several of the units (https://en.wikipedia.org/wiki/2019_redefinition_of_the_SI_ba...), so scientists must be confident we can reasonably recreate the base units from measuring various fundamental phenomena.
> 'I have seen' - excuse me, but what? Are you going to tell us that you work at a company where people's reproductive plans are common water cooler discussion?

No, but sort of, yes. I have witnessed many cases in which some employees practically disappeared, to the point of having to hire others to substitute them, for years.

Timing a pregnancy is not as uncommon as you'd think.
> What's the lesson learned from this?

That sleep is complicated, and that people doing scientific case studies contributes to the overall corpus of material we have to inspire others.

There need not be a breakthrough everytime you do a case study for science to be useful and we should stop expecting that.
It’s because on HN we don’t see the :rofl: emoji in the original post being quoted. Loss of meaning without the emoji, I’m afraid.

Which is exactly the goal of those unicorns in the first place. Once you've smothered the competition in investor money, you're free to raise prices to profitability and beyond.

Besides mechanical parts you can still see failure from weary chemical components (capacitors, easily fixed), solder joints (fix depends on the joint. BGA chips aren't easy to fix) failing due to cycles of thermal expension and retraction or water damage, and lastly electromigration (the real unfixable damage, it usually happens from overvoltage/overheat).
I'm working on this exact problem except for an autonomous boat, so probably it's completely transferable, so this is nice timing. For now though I think I'm going to use a much simpler autopilot system (that I've already coded): Accelerate towards target at maximum speed; if within a certain distance of target, slow to approach speed (10%); if within "arrived at target" distance, cut speed to 0 (station keeping). This seems to work "well enough" in my JavaScript simulator, but I really wonder how it will do on actual water.
Well, I would guess twice as much and four times as much respectively. I mean RAM is cheap today but if you wanted 128GB of it today it’d still run you like, $700. I can’t pretend to know what this particular type of RAM cost back in the day, but given how relatively cutting edge the machine was I can only guess it was not particularly inexpensive...
Alright, let me rephrase:

Hate speech is subjective. Minority is subjective. Even if there are commonly considered minority groups, it doesn't solve for the definition of hate speech other than just being a shortcut to defining a group membership that is the basis for the "hate".

Therefore there is really no connection (essential or otherwise) that is useful to the discussion of what is hate speech.
> I think you're being pedantic

But I don't think it is pedantic to point out there is a difference between

1. Maximizing your time off work, even if it screws over your employer.

and

2. Timing your pregnancy in order to screw over your employer.

You're being disingenuous by making it sound like GP is arguing that they are doing it in order to intentionally screw over their employer, when clearly GP is saying they are doing it to maximize their paid leave, which also screws over their employer.
I would argue this isn't true. I lived in Santa Monica when the scooters came about and once they removed the helmet law I loved the utility they provided. I lived about 2 miles away from downtown Santa Monica, which is totally walkable and I love walking, but sometimes I wanted to meet up with someone in a more reasonable amount of time. Instead of having to order an Uber for such a short trip, I would check Bird or the Lyft scooters to find one close to me, jump on it, and be downtown in roughly 10 minutes. And they're fun to ride!

Now Santa Monica does have a great bike share infrastructure that I also used quite a bit, but nothing is more frustrating that getting on a well used bike and having the brakes hardly work or the crank constantly slipping as you push the pedal downward. Don't get me wrong, you can totally get a bad scooter that isn't running well, but I think I ran into more worn down bikes, likely due to the bike program having been around longer.

My 2 cents, the more options the better.

EDIT: Also wanted to note, Santa Monica has a lot of bike lanes, which made riding the scooters around much easier and safer from my perspective.
Introduction to Serverless: do you need a PhD to build a cloud app?
Reminds me of the iterated prisoners dilemma style party planning I've experienced with my compatriots, where the host expects everyone to be at least an hour late and sets the party start time an hour earlier than they want, and of course the guests expect this and show up two hours late, and so on. The few people (host or guests) who take start time literally are slowly driven insane.
Back in the 1980s this was expected of MIT undergrads. Took me over a decade and some difficult effort to extract myself from chronic lack of sleep. I feel likeI was a lot smarter and more productive when I get 6 hrs minimum. I am a lot healthier on other metrics as well.

Perhaps this shows that a coupled weeks is OK. Certainly it helped me in my 20s — I could hold down a job and still spend evenings at clubs with my gf and then wife. So in that way I was a good spouse(!)

A broader study would be interesting too — according to my pediatrician mother I didn’t sleep much even as a baby / toddler.
Haha, this is exactly what I was thinking reading this. I'm a single parent of 2 kids and the sleep-related impact on my cognitive ability is, uh, marked ;)
Exactly. I think some HNers would be amazed if they read the terms associated with Tesla doing business in China.

> You have insanely large pools of capital creating an incredibly inefficient money-losing business model. It's used to subsidize an untenable customer expectation. You leverage a broken workforce to minimize your genuine labor expenses. The companies unload their capital cannons on customer acquisition, while this week’s Uber-Grubhub news reminds us, the only viable endgame is a promise of monopoly concentration and increased prices. But is that even viable?

Are there historical examples of this strategy working? I can't think of any off the top of my head.

Uber's bet is that the desirable customer experience (quick, cheap delivery) is tenable with both 1) scale and 2) new technology that drives prices down. In the long run, I think they're right:

For #1: When you consolidate two (or more) local delivery operations that do the same thing, you can increase the efficiency of your operation as a whole.

For #2: The big question is: can they stay solvent long enough to see autonomy or other delivery technology come to fruition? I have serious doubts about this. I expect we'll see Uber slowly raise prices to keep the business sustainable.
This study can lead one to conclude that at least some people can function well for short-term periods of sleep deficit, at least when performing stimulating activities.

However, we also have studies showing that people are very poor at recognizing when they are being affected by sleep deficit, so you would need to run this experiment on yourself first before concluding it applies to you!
