I've thought to myself that if I want a cool project that would motivate me to re-learn C just for the sake of making an NES game (ala 8-bit workshop - https://8bitworkshop.com/), I would really like to learn how to apply the pseudo-3d or 2.5d methods that were used by Microprose in F-19 Stealth fighter.

I don't know the first thing about 3D programming. I tried to follow a book on writing a ray-tracer from scratch just to see if I could pick up the principles and do it myself, but I got frustrated by the ambiguity of the approach. Like I was trying to use Ruby with Rspec, but I'm not even sure if I'd run into a performance issue or not be implementing the interfaces correctly.

I just want to know what method was used. Maybe 3D projection?

https://en.wikipedia.org/wiki/3D_projection

Microprose had 3D flight simulators going back to 1984 on Atari 400/800, Commodore 64, and IBM PC. That's really impressive.

https://en.wikipedia.org/wiki/Hellcat_Ace

Kind of like how Myst was able to deliver ultra-high resolution 3D images in a video game in ways that had never been done before, even though it was really just a point-and-click slideshow with embedded videos and scripted interactions (Hypercard)... Hellcat Ace provided an experience far ahead of its time.

None of them? The auto industry seemed to be convinced that EVs were impossible until Tesla showed them the blueprint.
I'm looking forward to the mass production of next-gen robotics platforms and components; hopefully these companies will get a good product improvement feedback loop going like other manufactured goods (cars, batteries, screens, electronics, etc). Once that gets going and they can sell reliable actuators, control systems, and chassis components on the mass market for cheap, then robotics is going to get crazy.

Hopefully we get some open source designs as well, and open collaboration in the engineering community.

And hopefully humanoid robots don't turn out like most "smart" devices, where all the guts are closed-source binary blobs the user has no control over. (I'm sorry Dave, I'm afraid I can't do that). Not to mention the consequences of having your humanoid robot hacked remotely could be quite horrific...
No offense, trying to help: this is a whole lot of mind reading wrapped in condescension. You have absolutely no idea what their health status is, and COVID is still COVID. With wide vaccine availability and the likelihood of 0 exposure decreased, the rest of us can giggle about malformed psyches, but there's plenty of people who still need to avoid it like the plague. I empathize with you, my instinctual reaction when I see someone masking outdoors is to roll my eyes. Then I walk through "well gee maybe they have it and don't wanna spread it, or, or, or..."
It is not the autism, it's high IQ. high IQ people are more impactful per capita. Online or offline. They write articles that are highly read and can affect policy. Or they lead social movements and put politicians in office. An example is Robert Mercer.

How does that very specific test distinguish it from the one-day flu or the 12-hour cold? The test makes no prediction of length of illness.

It does seem that in my quick search, I came across the 44% number which was then later corrected by the Washington Post but not before a bunch of other articles picked up on the wrong tagline.

In terms of the actional numbers, like I said, it's looking harder and harder to actually know the real number, and I'm not The RAND Corporation. From what I can tell, the number is at minimum in the double digit percentages. But it seems like a very slippery number that depends on how you define private equity, corporation, institutional investor, etc. and of course what "home" means.

As far as I can tell, my point still stands aside from the incorrect 44% number (which is still alarming, in my opinion).

Hey! I built this tool from my own struggles with ADHD and executive dysfunction. It helps you break down tasks into smaller steps, provides suggested responses, and recommends integrated tools such as timer and Spotify (ask it to play a song or set a timer).

People with ADHD operate on an “interest-based nervous system” so they’re motivated by urgency, novelty, competition, and interest. ADHD also impairs executive functioning skills. This can make task paralysis really common, especially for unstimulating tasks.

We’re a team of 3 undergraduate students who have received 50k as finalists in the Microsoft Imagine Cup. We’re being flown out to seattle for Microsoft Build to showcase our tool.

Our tool is in a very early stage right now, but we’re partnering with the world’s ADHD coaching academy to improve and make a tool specifically designed for people with ADHD. We’d love people to test it out and give us any feedback (positive or negative)

Damn, I had really high hopes for cue tests as an idea and company overall. In theory they could do big variety of various tests. They have mpox in the app, the promo materials we’re talking about STIs.

But this, together with recent layoffs (50% of staff, https://www.sandiegouniontribune.com/business/story/2024-05-...) seems like a death blow.

> When one gets to be a certain age one begins to become attuned to this tendency of others' emotions to manipulate you

This is incredibly optimistic, which I love, but my own experience with my utterly deranged elder family, made insane by TV, contradicts this. Every day they're furious about some new things fox news has decided it's time to be angry about: white people being replaced (thanks for introducing them to that, tucker!), "stolen" elections, Mexicans, Muslims, the gays, teaching kids about slavery, the trans, you name it.

I know nobody else in my life more emotionally manipulated on a day to day basis than them. I imagine I can't be alone in watching this happen to my family.

You don’t know their personal circumstances. Maybe they’re in the same situation as you (I’m assuming “generally in good health”), but they are just more anxious than you and you believe that’s unnecessary. On the other hand, some people - yes, in your workplace - are likely immunocompromised or caring for someone who is; disease risk is not evenly distributed and COVID did make this set of risks meaningfully and continuously worse.

You can’t tell the difference just by looking at someone.
Such a patina of reasonableness to your comment but your comparison of the Irish famine to the Holomodor is way overwrought. Holomodor was deliberate and largely not caused by bad harvests. Irish had the potato blight; and in the beginning they were given a large amount of charity.

Exascale is the primary target decided among everyone in the HPC community in the mid-late 2000s because FLOPS (floating point operations per second) is the unit used to benchmark, as there are various different variables like compiler, architecture, etc are very difficult to account for.

It's functionally the same as arguing that GB or TB are arbitrary units to represent storage.
Costco doesn't use special boxes either. Grocery store uses the exact same case boxes as you would get at a costco checkout, they probably just aren't generating so damn many around the clock because the quantities sold are much smaller, leaving you with fewer extra boxes to have customers deal with on their own.
That's a really interesting example, thanks.
Fortunately, chatbots are low on the hierarchy of AI capabilities such that someone will implement an open source one to run on-device. So I don’t think “chatbot services” is a long-term viable business.

> I wouldn't call anyone in the WEF a progressist. At least not because of that, since I consider the WEF a reactionary organisation.

You're right. WEF is globalist. Recently there is a strong convergence between globalist and progressist narratives but yep they aren't the same.

As I see the WEF and globalists in general are rich people buying their way into politics, stablishing a global financial elite in the seats of power. Do you consider it to be reactionary because it's in their interest to maintain the status quo?
Yet again very little attention is given to the touch sensing. No sensors on the back and sides of the fingers. I can grasp objects blind folded because of the richness of touch. It is super costly to try to compensate lack of touch with vision and all these robotics companies seem to miss this.

A big problem is the lack of innovation in touch sensing. We mass planar (sometimes flexible) products with millions of little active devices (OLED). Cannot be this hard to assemble a decent touch sensing planar device. It will be like a camera for touch and then all the beautiful neural net techniques can be used.
But that same point was made at every 3 levels of magnitude improvement in supercomputing history.
I watched the switch to proof of stake on the nodes I had at the time. I’m well aware.

But seriously, as a cluster sysadmin, the “128 jobs, followed by post-processing” is great for me, because it lets those separate jobs be scheduled as soon as resources are available.

> expensive resources with little support

Unfortunately, there isn’t as much funding available in places for user training and consultation. Good writing & education is a skill, and folks aren’t always interested in a job that has is term-limited, or whose future is otherwise unclear.

I don't want to paint with too broad of a brush but the role of a manager is generally to trust their team on specifics. So how would a manager be able to spot a hallucination and stop it from informing business decisions?

It's not as bad for domain experts because it is easier for them to spot the issue. But if your role demands you trust your team is skilled and truthful then I see problems occuring.
Related: 2024 NHTSA report on Autopilot:

https://static.nhtsa.gov/odi/inv/2022/INCR-EA22002-14496.pdf

"This analysis, conducted before Recall 23V838, indicated that drivers involved in the crashes were not sufficiently engaged in the driving task and that the warnings provided by Autopilot when Autosteer was engaged did not adequately ensure that drivers maintained their attention on the driving task. The drivers were involved in crashes while using Autopilot despite fulfilling Tesla’s pre-recall driver engagement monitoring criteria. Crashes with no or late evasive action attempted by the driver were found across all Tesla hardware versions and crash circumstances."
I want to get to the part where phone recordings stop having slow, full sentences. The correct paradigm for that interface is bullet list, not proper speech.
You’re asking on the wrong site; this isn't Reddit.

But your thesis isn’t that obvious to me; what is so confusing about it? You need to be very specific about these sorts of questions. As for the countdown, it just covers the time needed to send a request to the nearest driver and have them accept the trip or not. Lyft cannot simply assume that they’ll accept because they might be planning to take a break or even end for the day after finishing their current trip. The countdown can only ever be approximate, because the driver is human. Lyft can only guess how long it will take them to read the message and make their decision.

I'm not sure that Tesla showed anyone the blueprint of anything. If the air from the EV hype pops tomorrow, Kia and Hyundai could drop their entire EV lines with barely a hiccup. Tesla, not so much. And it was easy for Kia and Hyundai and others to wait for a market to develop. If anything, they used Tesla for market research, whereas Tesla needed to lean on venture capitalist money, government grants and subsidies, and cutting every corner possible to squeak out a handful of models that they can barely keep up with.

It's easy to get up to quite a high number of joins if you have a well normalised database that uses a lot of lookup/reference tables.

Common in a situation where you're writing for a presentation layer and you need human readable data.

30 sounds a lot, but I'm pretty sure I've written SQL with almost 20 while building an ERP application so I don't see why 30 implies garbage schema, just a complex one.

And as you say, it shouldn't be a problem anyway, there no magic number of joined tables where things stay breaking down.
The sentence order of the Arabic and Urdu examples text is scrambled on that page:

Arabic:
مرحبًا، اسمي جي بي تي-4o. أنا نوع جديد من نموذج اللغة، سررت بلقائك!

Urdu:
ہیلو، میرا نام جی پی ٹی-4o ہے۔ میں ایک نئے قسم کا زبان ماڈل ہوں، آپ سے مل کر اچھا لگا!

Even if you don't read Arabic or Urdu script, note that the 4 and o are on opposite sides of a sentence. Despite that, pasting both into Google translate actually fixes the error during translation. OpenAI ought to invest in some proofreaders for multilingual blog posts.
This may be a gripe specific to Postgres but I find that the documentation can be obtuse. Yes, I'm sure it parses consistently, but what a given word or phrase does in a given context isn't always clear. I've had to write a lot more database tests to be sure I know what I'm doing than when I was calling specific operations with well defined arguments in NoSQL land. Maybe this issue is mostly in my head, but the semantics of various operations seem a lot fuzzier than I'm used to.
The machines that the large ML companies are using are typically not going to run TOP500 competitively. They tend to skip the MPI stack, and weren't optimized for LINPACK performance. When I worked on TPUs there was no interest in attempting to benchmark them using supercomputer workloads (probably a good thing).

Unless they've been to an Aldi, which is massively exploding in popularity everywhere in the US right now since they're a perfect fit for the current economic environment.

Aldi has carts you put quarters in, and Mr Carlson tried to play up seeing the same thing in Russia like it was some kind of brilliant Russian innovation.

It was truly bizarre. So weird how far that guy has fallen, much like the also once-respectable Giuliani. Back in the 2000s or 90s, he used to just be the dorky bowtie guy on an old CNN show about a rightist and a leftist having a civil and friendly debate, if I recall. Now he's... trying to hang on making a living by... shilling for Russian despots and for Snu brand sniffable tobacco (really). It's pathetic.
I really wonder how that'll go, because workplaces already seem to limit human communication and emotion to "professional behavior." I'm glad he's thinking about it and I hope they're able to figure out how to improve human communication so that we can resolve conflict with bots. In his example (around 21:05), he talks about how the bot could do something if the person wants but there might be consequences to that action, and I think that makes more sense if the bot is acting like a computer that has limits on what it can do. For example, if I ask it to do two tasks that really stretch its computational limits, I'd hope it would let me know. But if it pretends it's a human with human limits, I don't know how much that'd help, unless it were a training exercise.
> If you don't want to pay the cost of updating the full JSON value, that's what columns are for.

You pay the full cost for writing the entire new row in PostgreSQL if only a single column changes. There’s some saving for indexes, but the row data is always written in full for the new row even if just one column changes.

Now that’s no reason not to use actual columns. The value of a well defined schema is knowing the types and constraints of your data.
To your point, there's been a lot of talk about AI, regulation, guardrails, whatever. Now is the time to say, AI must speak such that we know it's AI and not a real human voice.

Humans are lazy. The average person who steals a bike is not going to pull out a Bluetooth sniffer. And if they did, they would probably find dozens of nearby devices (try it yourself - I just did and have 53 Bluetooth devices near me).

Thieves will, however, reply to an alert that says there is a tracker following you and hit the "disable" button. Friction is key. Google and Apple are making it extremely easy for thieves. We are pushing back on this.
The same reason we choose to define a Gigabyte as 10^9 or use the Richter scale to measure earthquakes.

We need a benchmark to delineate between large magnitudes.

Furthermore, there are very real engineering problems that had to be solved to even reach this point.

A lot of noobs take GPUs, Scipy, BLAS, CUDA, etc for granted when in reality all of these were subsidized by HPC research.
