Show HN: Spartan HUD Smart Helmet for Airsoft, Milsim, and More
Hey HN, excited to show our latest project, the Spartan HUD Alpha, Augmented Reality Smart Helmet for airsoft, military simulations, and more.

See and shoot around cover, stay protected and gain tactical advantages, access real-time intelligence, surveillance, and reconnaissance (ISR).

Youtube:

https://www.youtube.com/watch?v=Bal8bYtxSbE

We've developed a functional and lightweight augmented reality helmet that lets you access the heads-up display of a full computer system, connected to your gun as well as a full desktop computer system. See and shoot around cover without exposing your head or torso. Have maps, drone feeds, video chat, and more in your heads-up at all times. Develop whatever applications you want on our fully open computer platform.

Currently we are running a crowdfunding campaign, but I don't think it's best to link it, instead I'd be happy to answer any questions and respond to your feedback and comments here. If interested, here's an email contact: info@spartanhud.com

Cheers!

o1 was what got you stirred up? It honestly feels like an incremental change at best to me. I had similar feelings about gpt-3.5, but since then my fears have normalized into a sort of dull, typical (for me) cynicism (so no sleepless nights).
Question for active professionals during the Moore's law era of computing. Back then, were executives writing such grand proclamations about the future ? In my experience, when things are working, executives are quiet. The outcomes speak for themselves.

Thankfully, we have a recent point of reference. The pioneers of internet & computing's 1st wave transformed civilization. Did they spend years saber rattling about how 'change was coming' ?
Wow! Didn’t know this!

I would’ve thought they would let devs handle it because if anything they’re more capable of these kinds of things (not counting myself ofc :-))
It's a thin silver lining.

I can't have coffee multiple days in a row, else I'll experience panic attacks (and in that moment i think I'm going to die, nearly reaching for a phone to call 911). And can't partake in coffee ~95% of the time (friends don't have decaf, a ton of nicer coffee shops don't either, and often decaf is neglected so i'm drinking black water). I still love the taste of coffee, so i've kinda been robbed of that unless i'm at home and can make it myself.
I guess access to plugins is way more WP DNA than post revisions, and yet Matt's own WordPress.com restricts access to plugins to more expensive tiers only. (Not to mention the “confusion” he mentions regarding WP Engine, which is explicit with WordPress/WordPress.com.)

But stops during anticyclones, which can last several weeks (that makes it completely unfeasible to use wind power with gas as a backup, because there's no way we can build several weeks worth of storage).

> Nucular continues

The problem is that nuclear plants cost is roughly the same no matter if they produce or not, so nuclear + solar is strictly costlier than just nuclear.

Solar in a country as cloudy and rainy as the UK, and one that is so far north it gets very long nights in winter, doesn't make make any sense whatsoever.

> He's allowed to be pissed off that some other company is profiting without contributing back.

Reading Matt's post, it's not my impression that he's really pissed about that – that seems more like an additional (less important) aside.

His core complaint is, paraphrased, "WP-Engine offers WordPress hosting, but all they offer is a bowdlerized version of it, which reflects badly on all of WordPress. So I'm pissed about it because I spent a lot of time and money on WordPress and I care about it a lot".

This sort of thing comes up every now and then in different contexts. A few months ago the Debian developer decided to offer a bowdlerized version of KeepPassX and was then excessively abrasive and rude about it when people complained. At the core, this is the same kind of disagreement/conflict.

All of that only amplifies your "he's allowed to be pissed". I'd probably be slightly more careful in my use of language, but I'd be pretty cross too.

Certainly doesn't seem like a resigning issue. The hell is up with that?

Kinda the opposite - Firestore documents don't inherently have a userId of the owner. Rather, they just have arbitrary fields.

Making all your documents have a `owner_uid` or `userId` field is just a convention they recommend, because it helps you write rules.

So rather: they have no default system for handling documents that can only be accessed by a given user, but rather you have to construct it using `firestore.rules`, and you end up with something oddly default-insecure.

And are used far less than car infotainment, by almost all of those folks.

It'd be better for everyone if there was some kind of modular, competitive ecosystem of infotainment OSes, but we don't even have that on phones (somehow the PC alone is the one neutral device).

Like, folks should be able to plug in a Chromecast dongle, that can then manage the car's subsystems, while outputting some DisplayPort screens.

Trying to keep sophisticated consumer electronics devices running & up to date & powering these expensive expensive platforms satisfactorily is a game we should want car makers out of. Car makers should want out of it. Having the product & it's whole lifecycle gated on the computer awful bedeviling coupling.

I think it's important that there is a big difference between a farmer as in someone who is out in the field doing laborer, and a farmer as in a large landowner who has a lot of other people out in the fields doing labor which historically in China, and also Europe and the US, was considered to be a kind of ideal person in many time periods. So I doubt anyone who was out doing labor in the fields could do great in the exam, but if you were a small local elite, this provided a path for your children to potentially rise up.

if you have a license for a good fast solver already for some reason, it can be very effective to reduce some NP-hard problems to integer programming.

also, one interesting application related to data science is to embed a machine learning model (usually regression, maybe decision tree or neural network) inside the integer program, and then maximize over its inputs. this can let you characterize worst-case behavior, or answer questions like "how must a user change their features to flip the prediction?".

solvers are so expensive that MIPs will probably never become part of mainstream data science, but they can be very powerful beyond classic OR problems.

Yeah, but under what circumstances such a control scheme actually be useful?
It depends on when you do the query. Years ago (mid 2000s) at ITA, Carl wrote code to find the longest possible shortest route between any two airports with scheduled flights. At the time the winner was Wasu, New Guinea to Peawanuck, Ontario, which took a minimum of 90 hours and many flights. There are airports you can only get to at the end of a long line of stops; this drives the number of stops way up.
Not really, unfortunately. The progress has been heartening, don't get me wrong, but it's more like $20B away from getting to the first steps of solving the next set of problems on the road to a fully functional fusion generator.

Those are fairly substantial. It's past time to stop being cynical about "ten more years every ten years", but it's also way too soon to declare victory.

Just as subjective as the OP, XD
The thing is that it looks like, or perhaps I should say it's "understood" at this point, that transformer's abilities scale pretty much linearly with compute (there is also some evidence they scale exponentially with parameter count, but just some evidence).

Right now there is insane amounts of money being thrown at AI because progress is matching projections. There doesn't seem to be a leveling off or diminishing returns taking place. And that's just compute, we could probably freeze compute and still make insane progress just because optimizations have so much momentum right now too.

He's always been one to think and write for himself. Huge respect for him. Even though it needles me every moment that they still call themselves "Open"AI, I have so much respect for the guy, especially because PG basically told the world he was the next Michael Jordan of startups, and he actually went and fulfilled that. Not many people have it in them to live up to hype like that (Lebron being the only other one I can think of OOTOMH)
Really insightful.

I'm a little more cautious though. I think GPT will be way more integrated, simply because it's useful. Stalinist language was artificial, in the sense that it was basically imposed on you from outside for no good reason. When you wanted to get real stuff done (either talking to close friends, being productive with colleagues, etc) you wouldn't use socialist newspeak because it got in the way. GPT will be imposed by the outside world, but it's actually a useful thing to be able to converse with a language model; you'll do it every day at work, when buying things, when using your phone/PC.

And also, unlike in USSR times, so much of our communication is online and visible. It would not surprise me if we develop a model that can train continuously on the firehose. Text is small. Data rate of every person on earth speaking simultaneously:

- 150 words per minute spoken

- 150 words × (5 characters/word + 1 space) = 150 × 6 = 900 characters per minute

- 1 byte per char = 900 bytes/min = 15 bytes/sec

- 15 bytes / sec * 8,000,000,000 people speaking continuously = 120 gigabytes/second

That's a lot but it's not even the bandwidth of a single consumer GPU.
my bet is that it's a repeat of the French revolution

What's critically missing in the current architectures, in my view, is models that are able to "keep learning" (in a way beyond just providing a summary of the previous conversation, which grants surface-level insights at most).

If we keep the current iteration cycle (retrain an LLM every couple of months, incorporating the current "status quo", including all of its previous conversations), we might get somewhat interesting results, but even the least motivated grad student has an iteration cycle orders of magnitude faster than that.

Show HN: I Wrote a Book on Java
https://www.manning.com/books/data-oriented-programming-in-j...

This book is a distillation of everything I’ve learned about what effective development looks like in Java (so far!). It's about how to organize programs around data "as plain data" and the surprisingly benefits that emerge when we do. Programs that are built around the data they manage tend to be simpler, smaller, and significantly easier understand.

Java has changed radically over the last several years. It has picked up all kinds of new language features which support data oriented programming (records, pattern matching, `with` expressions, sum and product types). However, this is not a book about tools. No amount of studying a screw-driver will teach you how to build a house. This book focuses on house building. We'll pick out a plot of land, lay a foundation, and build upon it house that can weather any storm.

DoP is based around a very simple idea, and one people have been rediscovering since the dawn of computing, "representation is the essence of programming." When we do a really good job of capturing the data in our domain, the rest of the system tends to fall into place in a way which can feel like it’s writing itself.

That's my elevator pitch! The book is currently in early access. I hope you check it out. I'd love to hear your feedback.

The emperor truly has no clothes here.

Six months ago, he probably could have gotten away with saying this and there would have likely have been enough people who were still impressed enough with the trajectory of LLMs to back him on it. But these days, most of us have encountered the all-too-common failure mode where the LLM shows its hand, that it doesn't truly understand anything, and that it's just _very very good_ at prediction. Each new generation gets even better at that prediction, but still hits its weird stumbling points, because its still the same algorithm, and that algorithm cannot do what he is ascribing to it.

These are the words of a man who has an incredible amount of money sunk into something and as such, is having a really hard time taking an honest accounting of it.
My cousins had a large collection from i guess the 70s and very early 80s that i read a lot. My mom and aunt had read them too. So one day i bought a new one at the store and brought it home and my mom found it. There was a parody of Edward Scissorhands, and one of the topiaries he made was of a middle finger. I didn't know what that was as she described it (flipping the bird). Apparently that was enough to get it banned in my house.

Incidentally, i got a parent teacher meeting for bringing some stickers from one of my cousin's Mad magazines to school. There was a "POINK" onomatopoeia with a lady's boob and a wardrobe malfunction on one of the stickers, and this was enough to warrant the third degree.

Mad magazine was pretty tame, i never got the puritanism exhibited by everyone around me, especially since they had read the magazine when they were young, and their kids, too, but i read the same ones and suddenly it's taboo?

This post demonstrates why I hate UI programming. The number of unpredictable, niggling little things that can go wrong exceeds my patience for dealing with them. I kind of enjoy thinking through the ways something might fail and writing tests to catch them, but aimlessly clicking around to see if anything breaks feels haphazard and annoying.

Is UI construction inherently that complex, or have we just not found the right programming model yet? Is it unreasonable to wish that sometimes things would just look and work the way I intended on the first try?
While true, I don't think it's something new and unique, and by no means it's "consequence of technology entering their lives far too early". If anything, it's author's inability to see a plank in his own eye. In the hindsight, it was 100% the same thing with us (me specifically) watching TV cartoons with sketchy ads in between. That was before MrBeast was even born, and while I may dislike him more than others because of his creepy face, he is literally an amateur compared to Coca-Cola and Paramount.

to save you time, this is a summary of the links various people here are posting:

popcnt of a word counts the number of bits that are "1"

https://www.talkchess.com/forum3/viewtopic.php?t=38521

the NSA wanted to do cryptanalysis on intercepted messages, and since the CDC 6000 had 60-bit words, one word was enough to store most alphabets they were interested in. They were able to:

Split a message into lines
Set a bit for each unique character they encountered per line
Use popcount to count the distinct characters
Use the count as a hash for further cryptanalysis

Curiously, popcount seems to have disappeared from instruction sets between the mid-1970s and the mid-2000s.

(of course for all we know this could be NSA disinformation ;)

That's the answer to the NSA question. There are other uses described here https://vaibhavsagar.com/blog/2019/09/08/popcount/ including for Hamming codes and Neural nets and more.
The way I think of it - we need a wrapper interface over our existing healthcare system so that any other entities and systems interfacing with the current one can continue to do so. And then we can swap out the underlying components with better ones, without breaking.
