Perhaps there should exist a flag for send() that would make it so that it doesn't return until all data in the send() call has been ACKed by the receiving side (with a user configurable timeout).

Of course, it's still not bulletproof. The other side can receive the packets, stuff them in its receive buffer, send an ACK for those packets, and then fail before draining the receive buffer due to an OS crash or hardware failure. But computers and operating systems tend to be much more reliable than networks, so it would still provide a much stronger guarantee of delivery or failure.

I think you're overstating things but I agree to some extent. It's a niche product but there's more niches than just "industrial". There's still a lot of interest from the arts and creative sectors for example.
Thanks for sharing your experience from the other side! I agree and would add that my manager gave me the impression that I was really talking to two entities: The manager (who really doesn’t want to do a candidate search) and Corporate.

People too often blame the former for constraints from the latter.

Tesla is also thousands of brilliant engineers that transformed the industry, and not just one guy who tweets a lot.
Tesla's not the only one who pulls shenanigans like this. BMW was charging annually for CarPlay for a while, and now they're testing the same for heated seats. If this trend continues, people will actually want a checklist of things to ask about, and perhaps a contract that says what features were paid for, how, and whether there are any transfer fees so the new owner can use them. Sad state of affairs.

> (I was going to say "TLS for example" though come to think of it this isn't even strictly true under Linux; https://docs.kernel.org/networking/tls.html )

TLS isn't that much harder to handle than regular TCP sockets--you're going to need a socket interface that lets you get reader and writer streams, and the extra roundtrips you need for negotiation are handled in the constructor for the TLS socket.

It is more difficult if you want to support more advanced features of TLS, or especially if you want to support something like STARTTLS (negotiate TLS on an already-open socket). But this is already kind of true for sockets in general: the reader/writer abstraction breaks down relatively quickly if you need to do anything smarter than occasionally-flushed streams.

I do the Thai Chi lessons everyday. I find the ping pong game is a great way to unwind, a 5 minute game is enough. I enjoyed the Star Wars Vader Immortal series. I use my quest for about 1 hour a week, so I am not a heavy user - but I do enjoy it. BTW, I worked in the VR field about 25 years ago for SAIC and Disney.
All they need is a few more decades and billions of cash to burn to turn this into a viable mass-market conusmer product.

> Uhh, that's 100% obvious. That's why it's not taught.

Is it? You probably feel that way from knowing how TCP works. But it would be quite straightforward to make it true with a slightly modified version of TCP (that acknowledges all packets, rather than every second one) by having send() block until it receives back the ACK from the receiver. (Yeah this would kill transmission rates, but it would function!) And furthermore, while it would be a terrible idea, the ACK could even be delayed until the end application makes the recv() call for the packet.

To somebody not familiar with the details (and why this would be a terrible tradeoff), something along those lines would be entirely plausible.
Foxhole was also the first thing that popped into my head. I'm not sure how "realistic" you can call it, but there are certainly some interesting interactions/dynamics displayed when it comes to logistics.

Agreed. They're giving the middle finger to people who can't afford a new one but were still interested in Tesla. Could have been a good opportunity to create loyal customers who are on a budget now, but could afford to spend more later in life.
Verdex presents: A Plausible Future

Driver: Okay Car are you ready to go?

Car: Sure thing driver, let's just hook up to the T-Network. Okay, we're in! Where's our destination?

D: Well, first thing is that I'm going to want a Mocha Frappe from the local Starbucks.

C: Sounds great! Off we go.

D: Wait, Car what are we doing at McDonalds?

C: McDonald's offers a wide variety of cafe style drinks at competitive prices. This includes your Mocha Frappe. 9 out of 10 baristas actually prefer the smooth taste of McDonald's Mocha Frappe to that of Starbucks. Have you had your break today?

D: No, I wanted Starbucks. Oh well, I guess we're already in line.

Menu: Welcome to McDonalds! What can we make for you today?

D: I would like a Mocha Frappe.

M: Oh, I'm sorry, but I'm afraid out frappe machine is broken. What else can we make for you?

D: Really? I just wanted the Mocha. Okay Car, can you take me to Starbucks now?

C: Sounds great! Off we go.

D: No, Car, you just left the McDonald's parking lot and then came right back. They don't have any Mocha Frappe's here. They said their machine is broken.

C: McDonald's offers a wide variety of cafe style drinks at competitive prices. This includes your Mocha Frappe. 9 out of 10 baristas actually prefer the smooth taste of McDonald's Mocha Frappe to that of Starbucks. Have you had your break today?

> illegally and fraudulently

How so? The car clearly had increased range at the time of sale. Tesla clearly approved of it at the time or they wouldn't have let it happen, and companies sure as hell don't get to take back stuff after years of condoning it because it was "by mistake".
This fucking exactly.

I'm fucking over it. If I "own" the device - legally I should own a key to EVERY fucking lock inside it. Digital or physical.

This attitude that it's acceptable to put a little green man inside of something you sell, and then retain control over that sold item using your little green man is insidious and immoral. I want it fucking banned yesterday, and it's rapidly becoming one of my strongest political opinions.
They're willing to tear up the streets, install rails and run those slow-ass streetcars down the middle of the road.

Also I imagine that getting enough power to your charging facility to charge 50+ buses up overnight isn't going to be any small feat either.

At least with the overhead lines, you don't have to worry about charging. You don't have to carry heavy, expensive batteries either. Though you do get the occasional "derailment" where the bus comes off the line. But the bus drivers are able to fix that themselves.

I think it hurts the resale value of their vehicles IMO. How much that hurts the retail value is dependent on the customer base. Like you said, if the base is like the classic apple user who just wants the newest shiniest tech, then they already expect the cost of the vehicle to be sunk. But Apple's goal isn't market penetration, exclusivity is part of their brand. Tesla on the other hand seems to have a goal of replacing as many gas cars with EVs as possible. I think marketing exclusivity conflicts with the goal of market penetration, and the only reason it hasn't become a problem yet is because everyone assumes their car is losing value already.

But if Tesla wants to sell a car to the other more frugal 90% of the population, they're going to have to cut this shit out.
Yes, thus the XYZ part of my comment explaining what issues they were trying to deflect with (those issues aren't even in the same industries)

What Old English reveals about the culture
I agree. The only true sustained usage I’ve seen it is industrial training which is why I mentioned it. But yes there are other uses for it.

It’s mind boggling to me why or how Zuckerberg decided to invest so much on it. I wonder if it’s just a screen for the stock price not to collapse as he loses DAUs, and certainly young people, to TikTok and other apps. Because otherwise it doesn’t make a lick of sense to me.
One thing that's happening is the weight penalty for EV's is dropping. Possible it'll invert with EV's being lighter.
The problem becomes a lot more difficult and interesting once you start involving multiple people.

Should everybody have many or exactly one task assigned? Should one person be on stand-by for operations? Should tasks be paired to two developers? Whole team mob programming one task? Are all the tasks truly independent?

Should juniors in team have same WIP as seniors or is the limit counted for the team as a whole? I see some teams almost give juniors a backlog of their own with the most basic cookie cutter tasks, even if they are low in prio, just to get them on board. Other teams handcuff them together with a mentor doing normal tasks. Vice versa for tech leads who often have another set of tasks only they do.

If everybody is working on a task, then who will code review others work? This can end up in a priority inversion situation, if Alice finished working a high prio task, should Bob working on a low prio task drop his work to review Alice work or should he finish his existing work to keep within his WIP limit.
The odd part is the OP said it was "badged as a 90" which to me implies Tesla also removed the physical badges on the car and replaced them to indicate it was a P90. That, to me, really implies they wanted to make this a P90 car.
> To be extra clear, I don't post this stuff because I hate Tesla or anything. In fact, it's just the opposite. I hate seeing Tesla derail themselves with this kind of nonsense.

I respect the OP for saying this. But I have a hard time respecting people buying Teslas, or anything from Musk. Is it not obvious that the guy is a charlatan? (and that the fish rots from the head?) How likely is it that you won't be robbed blind if you try to do business with him or any of his ventures?
Thanks for the seemingly well informed opinion. I, too, would like to see VR labeled more as a “tool” rather than “the future(!) of {education|recreation|work|etc}”
You can use a Oculus Account (not connected to facebook) and then use Virtual Desktop to stream the game from SteamVR over Wifi. If you have a Wifi 6 router it's the best PC VR experience you can have (wireless, no base stations, really high resolution, very low latency) and besides the Quest 2 and Virtual Desktop you are not giving any money to Meta. If you are worried about battery life, I already player with a battery bank in small backpack without any problems! Absolutely awesome.
Except everybody is already using UTC, and will not change from UTC to "Unix epoch time" on your say-so. Or to TAI or any other crack-brained system you can think of from your armchair, including all the hardware that cannot be changed without throwing it away and buying new.

All we need to do is simply choose not to announce that all the software in the world that (might have) "got leap seconds wrong" but still has to talk to the other half that (might have) "got leap seconds wrong" will be officially broken, this year. Or next year. Etc.
> I'm shocked that there aren't more multiplayer VR experiences.

Interesting, I had the opposite experience. While browsing the Quest's store I kept feeling railroaded into multiplayer experiences. Huh.

One huge issue, however, is with local "multiplayer". If you've ever tried to observe someone playing Beat Saber on the Quest 2 you'll know what kind of letdown it is: the video stream is delayed, which completely destroys the ability to enjoy watching someone else play. It's impossible to get "pumped up" when someone is doing well. They reaaaally need to release some sort of dongle set to get low-latency observer streaming to the TV.

Additionally, watching someone else's VR POV on a standard flat TV can be pretty nauseating. It would be great if there was also a way to add motion stability to the TV feed.
Your drawback of Mobilecoin is identical to Monero.

I am still in this journey myself and what's really made it a lot easier is seeing it as a skill that has a lot of opportunity to be improved, with regards to speed/effeciency, ie how many net minutes per week I actually have to spend.

There are so many ways to tweak and "automate" this, much like the effeciency of software development tasks, such as finding pairs of recipes that reuse the same intermediate components, making things in batches that can be frozen and reheated, and just plain getting faster at making something from practice.

There is a lot to be said for making the same recipe many times rather than always trying new ones. Each time you make it you will get faster, and even better, more able to do it without thinking much about it, and keep thinking about something else more useful instead.
Aaaah thanks, seems I really should turn that on. I always assumed it would still insert some [deleted] parent or whatnot if you leave it off. Was really confused by all these top level comments written like replies.
There are some techniques. Vignetting the borders of the screen when moving/turning seems to help for some people.

I've noticed newer games increasingly have free movement as an option, or no teleport at all, so I think for a lot of people it is possible to get used to it if you play enough. Some percentage will never get used to it though, which sucks.
Could they rent it out?
It's bigger than just Tesla. Someone should make a site with a checklist for the type of car you're buying, so you know what to ask about. And then have a contract that the seller signs indicating what he paid for and if it will transfer. Think BMW heated seats, for example.
I think the most actionable advice is: Bringing a sizable audience to a new social platform makes it easier to reach #1 in the rankings. Once you do, other things become exponentially easier.

It has to be. When I ordered a few months ago the device arrived the next day. I couldn't believe it.

Even though the hardware is somewhat aged and the platform still has bugs the overall quality, delivery and onboarding experience was good. The accessories to flesh out the kit were also inexpensive. The whole thing feels underpriced, however average people are definitely not ready to put on a headset.

This is MUCH different from the flip-phone to smartphone transition. Pricing has to be low because there's major adoption friction to overcome.

I've said it before, but I loathe facebook and can not support Meta or its aims until it splits off a company that can not and will not use data built from Facebook / Instagram or any other entity connected to FB.

The only thing that gave me solace in adding data to my shadow profile was that I knew the purchase was costing them much more than was sustainable.

That has pretty much been the consensus opinion since the name change, so no, you are not the only one.

The only people who I see consistently calling Zuckerberg's empire "Meta" are financial types that care about name of the company granting shares and on the stock ticker, and reporters who have to do copy editing.
The immersiveness is fantastic, but movement feels like trying to use a 1970's pong controller while something is strapped to your head.

I want standard joystick-based movement. I suppose too many get motion sickness, or that joysticks are ergonomically awkward to place onto motion controllers while maintaining the "pointing" and "picking up" metaphors.

VR's "aim and teleport" mechanic is the worst, though. It ruins the entire experience for me. I just want to walk in a direction - easy with a game controller. But instead you have to aim, judge distance, and click. It's so weird and feels gross.

> The main immediate threat is not disposal or even fire itself but the release of hydrogen fluoride _during_ a fire. You have to avoid airway and eye exposure at all cost with HF. This is probably the main difference in an EV emergency response as opposed to other chemical fires.

At any chemical or vehicle fire, firefighters are wearing SCBAs.

> The second main issue is securing an electrically safe chasis during crash and vehicle extraction (if you need to start chopping the car up to extract someone), you need to know what to cut and when.

HV cables are extremely clearly marked (bright orange, a color not used for any other component.)

HV cables run directly from the battery to the inverter. Extraction involves prying doors / cutting door hinges / cutting roof pillars. Not chopping up the floor.

HV cables are not energized after a crash because every battery, EV or hybrid, has an internal contactor that fails safe. There is also usually a clearly marked physical plug that can be pulled.

I love it when people jump on internet forums and talk authoritatively and demonstrate they know absolutely nothing about the subject at hand.
Postgres is great and replicating it can work as well. One benefit to SQLite is that it's in-process so you avoid most per-query latency so you don't have to worry as much about N+1 query performance issues. From my benchmarks, I see latency from an application node to a Postgres node as high as 1 millisecond -- even if both are in the same region. SQLite, on the other hand, has per-query latency overhead of about 10-20µs.

Another goal is to simplify deployment. It's a lot easier and cost-effective to just deploy out 10 application nodes across a bunch of regions rather than having to also deploy Postgres replicas in each of those regions too.
I agree. Games are selling 10-20x more on the Quest compared to the PC. It's making VR accessible and cheap for everyone. And the market is open for someone else to release a cheap headset if they like rather than requiring people to spend thousands of dollars and have complicated setups.
I view the Oculus Quest in the same category as 3D TV right now. Yes, it's REALLY COOL. But 3D TV was also really cool, especially watching Pixar movies which I did all the time when I had one. It has potential, but it's just not there beyond some initial great stuff.
When we first moved to my current home, which has two rental properties on the lot, we received a large amount of junk mail for a woman we called "the queen of junk mail". Columbia House was a major sender and we found it particularly offensive because there neither a way to opt out or to find out what exactly the offer was going to cost.

After throwing out what must have been twenty solicitations we finally accepted one in that person's name.

We got the CDs and soon later a bill, which we ignored. We received correspondence for this person for about two years, sometimes threatening, sometimes cajoling. Incredibly, this person eventually received an offer to "come back to Columbia House" -- after accepting that offer we never heard from them again.

As long as the poor guy can choose to work something better wages and working conditions will reflect this (or the mine will shut down). See Europe after the black death.
Exactly this. Warranty replacements aren’t a new concept, and I have a feeling if this were any other brand HN wouldn’t be so insistent on taking a step back and thinking about who else besides Tesla can be blamed when customers get the short end of the stick.
Thank you for this response!

It's sad to see that Swift is so slow in this particular case given that it has the potential to be such an optimized language (strong typing, compilation, backing from Apple).
