I find it amazing that governments can spare the time to regulate phone charging ports but completely fail to address this sort of gouging. If I buy hardware that can do one thing, I should not have to pay a license fee to enable that thing.
The idea of reaching mastery at anything within a year is highly dubious.
Trilium.

Android autocorrect thinks there is a word "trillium" already. So, maybe trelium or terlium. Or live with it, as we do lama and llama. Dreilium? Internet would probably go all in for threelium. Or heliumy-mc-heliumface.
Cars are the perfect source of smart consumers, you can think of a smart consumer like storage since they allow you to shift load but without having to pay the price of the round trip efficiency loss.

They sit still for 22-23 hours per day allowing making them perfect as long as we have chargers wherever you park your car. Which should be an easy mandate to enforce.
The cool thing about it and what does give it the 10k year feel is that it grows in a spot that was only low enough for trees to grow 10k years ago because the mountain has risen 100 meters since, and it couldn’t start growing there now.
I think governments should create a digital equivalent of cash. They should put strong safeguards in place to make it as anonymous as cash. Maybe even protect access to these records even at a constitutional level.

I think having such a digital cash system could revolutionize online commerce. Right now you need a fair bit of "capital" (know-how) to start a small online business. You can't just set up a street stall or garage sale like you can with cash. I think this makes it harder for people to get a foot in the door for entrepreneurship. A government-run digital cash system would make it possible again. It might also allow a reasonable alternative to the current ad-based economy.
Yeah, fight.

Most of the changes aren’t relevant to upstream - a lot these companies seem to be using Postgres as a frontend over some kind of secret sauce, usually related to custom storage or deployments or the like. Postgres seems very modular and pluggable that way.

I assume for the common Postgres core changes everyone is already incentivised to contribute changes back upstream - the companies are banking on Postgres popularity can need it to have an excellent reputation even outside of their specific customised offering.
I think you’re confusing Element and Synapse. Synapse is the reference implementation, Element is the client. And it can definitely be a resource hog on some end systems but it seems pretty fine in general
I feel that almost every city that has an "historic downtown" is now also quite a bit larger than what that area defines, and that prior to the car, most cities were developed to take advantage of geographical features that could make certain types of business more profitable or even just possible. If the density was mostly a function of timely access to these features, then it's entirely understandable why we abandoned it as soon as we had the option. And why city boundaries started to grow around the same time.

In what years was that system operating? Los Angles wildly expanded in size from 1912 to 1915, and it looks like most of those systems struggled to be profitable before this point and were only further hampered by the expansion in size and the low ridership of rural lines. It seemed they were unable to accurately match rail with demand in most cases.. and most rural/suburban people were already beginning to prefer cars.
> I find it dangerous to a) put nuclear and hydro/wind in the same "non-emission" category, especially when nuclear does emit radioactive solid waste and the occasional radioactive cloud when they go boom, b) to reduce the comparison to a price-tag, where indeed nuclear will win

It doesn't emit anything, radioactive waste is captured entirely on the other side. They also don't go boom.

They're in the same category because they're both zero-carbon power. If you want to compare safety, deaths per TWh has nuclear right in the same area as wind and solar - less than rooftop solar.
Firewall is unreliable as well. What if someone temporarily disables it and exposes vulnerable services? What if RabbitMQ opens a new port that you forgot to block in a firewall? Firewall is a hacky workaround, not a proper solution.

I feel like, most commenters are speculating too much around Tesla and their lack of FSD capabilities being the issue. Perhaps Karpathy just felt that the work was too draining and decided to he needed a break. I believe Karpathy has recently been on a lengthy sabbatical.

My point is, people leave their jobs for many reasons other than how well the company is doing. At least I hope so.
Hard Seltzer Has Gone Flat
I don’t think this is the case in any meaningful way, especially through the 401k mechanism, as participants are forced to delegate their ownership rights to the fund manager, which is yet another layer of dysfunctional fiduciary abstraction. The latest set of developments here are the fiduciary duties to ESG, which was intended to align long-term interests of fund participants and fund managers, but has been warped into a tool for fund managers to control investment flows arbitrarily by ESG ratings rather than by passive market indicators. It’s easy to see how this could be abused in a scenario like the listing and then de-listing Tesla in the ESG index. Smaller private equity funds can nimbly adapt to front-run the bigger funds even without prior knowledge of the rating change. This does not rule out the possibility of either prior knowledge or purposeful manipulation; easy to do and hard to prove.
I think Introversion Software's "Subversion"[0] is an excellent case study for the kind of problem Niantic's games always had: all tech demo, no game.

Ingress was an incredibly exciting technical innovation at the time. The idea of playing an area control game using your real world GPS coordinates was novel and the game encouraged genuine discovery in its initial phase by allowing you to record local points of interest: even in your hometown the game might lead you to walk down a road you were unfamiliar with and discover an interesting monument, fountain or building.

But they never really considered where to take it from there. Once the novelty wore off, it was mostly grind. Advanced players quickly developed strategies to optimize their play and "casuals" quickly fell behind with no way to catch up. The game remained fun for a small core group but effectively lacked an on-ramp for new players. Pokemon Go repeated this problem. They had created new exciting systems but not figured out how to make the game sustainably "fun" for most players.

I can only recommend watching the entire Failure Masterclass series from Introversion Software but at least the final video addressing their most anticipated game that never was, Subversion (a spiritual successor to Uplink). Without spoiling too much, the game was becoming increasingly complex and interesting but ultimately failed because there was no "game" there that would survive contact with players.

Booming != effective. Look around SV, how many companies produce genuine value?

Anyway, even agricultural output grew in USSR until mid-80ies and, importantly, salaries were at least double of city workers' salaries.

Is this usable for a general public? They don't seem to mention anything about encryption.

I have played with Matrix on several occasions. I think one of the big promises was E2E encryption and as those who have worked in the area know it's not an easiy problem to solve. I have accounts on more than 1 homeserver. I have various keys in my password manager which I don't necessarily understand how they are used. I have old messages that I cannot decrypt, despite being sure that I have never lost any keys.

In summary: In my experience Matrix has not been an easy experience even for a user of gpg.

Here I am not asking how is this made secure and usable. I am just asking is this usable for anybody who does not even know what a homeserver is, would never understand what a key or fingerprint is and has no account yet?
Indeed, I didn't think about that.

Tesla wasn't the first. I don't know who was but I know the differences in many printers are software only. The differences in many GPUs (Nvidia Quadro vs non-Quadro) are just drivers.

I don't know where to draw the line. I hated that Tesla has a (pay $2k for a software upgrade for acceleration). Imagine it will escalate. Pay $1k to get your air-conditioner to 60f otherwise it stops at 68f. Pay $3k to turn 15 degrees sharper. Pay $1.5k for your defrosters to work twice as fast.

On the other hand, my phones, computers, and game machines, all came with no software and I pay for apps and Apple in particular has made it popular to pay for individual features inside an app. Download a photo editing app and it will be $2 for the blur feature, $2 for the tilt-shift feature, or $10 for all features... though now it's escalated to $XX per year on most iOS apps that have top end features.

I don't know how to feel about it. I used to pay ~$50 a year for photoshop (upgrading every other version for $200). Now I pay $120 a year. I mean, I like the idea of paying once but the truth is, for software I actually used, I'd pay for upgrades, even if only to get the software working on the latest OS version.
Yep. And familiarity with Reddit/subreddit memes and inside jokes. And entire subreddits devoted to parodying styles of comment which are utterly earnest on other reddits which I'm not sure how you'd even begin to classify...
Language is hard! Even I, a seasoned native internet dork, have trouble knowing if someone's comment is sarcasm, irony, or something in between. Also, new phrases emerge all the time that turn a phrase on its head, and it has a different emotion.

The Economics of a Nuclear Reactor

idk, just leave it out? it'll work
Yes, the vision only approach isn't something that you do in robotics.

There is usually a hierarchy of sensors, mainly for redundancy.
Example: Bumper sensory at the wheel base, sonar / Lidar at the mid, and a camera at the top for advanced sensing.

For the sake of cost cutting Tesla has done away with their radar sensors at the front of the vehicle. It would be a substantial cost overhead, but have very real repercussions when it comes to safety, while also providing a "ground truth" to what at least the front facing cameras are seeing.

I don't think Lidar is a practical sensor for them to adopt, because it is quite bulky and has limited viewing angles, but I would expect them to have adopted some novel, lower cost radar solution.

Apart from the lower cost of the camera, I think Elon's rationale for having a camera only FSD is not valid, has made the problem needlessly complex and unsafe. He believes since we have eyes, and we can drive a car, then it should be sufficient to drive the car, but we only use eyes because these are the sensors we were born with, it is the best we have. In my mind, Elon's approach is like looking at a horse, and saying to yourself, that you want to build a car based on a horse, where instead of wheels, you have four mechanical legs, and those mechanical legs are limited is so many ways, but they should still at least "work", but there is no reason to limit locomotion in that way. The same with the vision system on a FSD, the whole spectrum of light is available, with any number of configurations, providing data at rates and with precision far beyond what a camera system can do.

I had hopes in Shein but it was way too ambitious with way too less design (in the sense of UI/UX and art).

Shein never became a serious language. It's highest point was when @deech made a talk about it and it also promoted their klambda but it had constant problems on every single aspect of the system and the design, from code size expanded as macros to unusable APIs due inconsistent design of libraries and features the author collected from everywhere. I even bought the book and felt deceived after it's unsuitability for anything other than academic examples on how to implement itself.

That's a good opinion that isn't really relevant to the fact that in retrospect everything worked out great. What harm specifically are you seeking to point out?

Depends what it is. I've had reasonable success with "validating" ASR transcripts by loading up the annotator's transcript, running the audio at 2x speed and just clicking "yes" or "no" to keep the good ones and bin the bad ones. It's roughly 5x faster to do this than to come up with transcripts from scratch, so if the annotators are 5x cheaper, then you come out ahead. You can go even further and pre-filter labels to discard any where inter-annotator agreement falls below some threshold (i.e. 3 people label the same piece of data, and you only include a sample when at least 2 annotators give the same label). You can also use that to discard all annotations from annotators who regularly disagree with the majority.

This is just the reality of outsourced data labelling. One thing I think is really important is to structure the compensation well, so that labellers get paid more when they do a better job. Paying per sample is a terrible idea, and even I was guilty of this - back in university I was paid $20 or so to hand-write 500 words on a resistive touchscreen to train a handwriting recognition model. I won't say I half-assed it, but I remember trying to get through it as as quickly as possible to get my money and go for beer (I think I also justified it to myself on the basis that sloppy samples would help make the bounds of the dataset distribution more robust!).

How about, "LETS F*ING GOOOOO YOU DINGBAT", now if that's a comment between friends the addition of the insult might be said in jest and still be impatient/enthusiastic, or does by adding the insult to the end automatically label it as combative?

While I generally agree with the prevailing sentiment here I actually managed to implement a captive portal with surprisingly little trouble (ubuntu + haproxy). Use case was an offline WLAN where I needed to direct users through a specific flow / landing page. All up it was less than a day's research and work, plus the landing page build.

Found some decent resources in the process such as https://captivebehavior.wballiance.com/

Happy to provide further detail if anyone is interested.
The old (inaccurate) labels were so completely utter shit (pardon my French) that it may as wel have been random.

I honestly believe most MTurkers just clicked random BS in order to complete the tasks as soon as possible.

What I ended up doing was make some Python CLI-based took that made it extremely fast for us to classify messages; after seeding it with about 1000 classifications, we would then focus on the messages based on certain dimensions: eg “contradictions” (“positive” and “negative” being closest as possible, or “angry” and “happy”), “least” (it was surprisingly difficult to find positive and uplifting tweets, and you don’t want a dataset with 90% negative messages!), etc.

That way we worked our way through the dataset and were able to get a pretty decent dataset in about a week time.

No idea how others approach this type of problem, but it’s what I came up with.

When did you sign up? I just signed up, and it sounds like it takes a year to get access, probably longer now. It's a bit frustrating because I didn't sign up when it came out because I didn't need it at the time, but now I'm afraid of waiting a year when I do. These types of waitlist systems encourage everybody to sign up for everything on the off-chance that they might need it later. Wish they just went with a simple pay-as-you-go model (with free access for researchers and other special cases who request it), like how Copilot does it.
There were workable proposals for private, cryptographically secure digital cash way back in the early 90s.

> Plus points for showing the world that you don't need a blockchain for this :-)

Who said you did need it for this feature in the first place? I don't think anyone did.

Since no one suggested to use a blockchain for this particular feature, it is more likely that crypto supporters want to add crypto wallets in messengers which is what most competitors have already done, unlike Element. Notably Signal which still has a crypto wallet where I see many Signal fans getting extremely upset about that.

You better pray and hope that Element does not introduce a crypto wallet, just like what Signal, Session, Keybase has done.

Well, you are asking about disabling borrow checker here, one of the main selling points of Rust and rustc here so I think that's out of the question.

When you do full comparison of what rustc does, and compare it to what you need to do in C++ project to match it, the compile times aren't actually slow since rustc does more with actual guarantees.

Thanks! Interestingly, Motif was based on Windows 3.x look, more precisely "Presentation Manager" look designed for OS/2 and Windows. You can see the similarities in how resize corners and close buttons etc are laid out on windows.

Windows 95 was a phenomenal success IMHO in terms of UI design, and it was partly based on Cairo which got a lot of inspiration from NextSTEP, but Win95 became so widespread that it became somewhat bland, so I agree in that sense. I strongly recommend the story about how Windows 95 team achieved excellence in the UI design, especially the "Start" button and Taskbar, the things that we take for granted today: https://socket3.wordpress.com/2018/02/03/designing-windows-9...
