I see easily a difference on text rendering on a mac os retina display (3k on 14") vs. 4k 27" oled. 1080p is horrible obvious on basically every display size i own.

And my smartphone or my DSLR take pictures with more than 4k, you can see the image sharpness difference also immediately.

What content is left? Games, but they also have text. Higher resolution, less antialising needed.

The most frustrating thing about this type of discussion is: Its 2025! 4k displays exist for how much in consumer space? 10 years by now?

8k is also nice. Might actually be something i don't pay extra for, but supporting 8k opens up so many possibilities. Like controling 4 4k displays without issues (demo walls, event setups etc.) or just 2 or 3 24/27" displays on your desk.

This is the problem with the dialogue around Musk. He's not 99% vaporware, he's 80-90% vaporware. That's problem enough.

In some cases, like Tesla, the vaporware is propping up the company (pivoting to robots!) even though sales are crashing because of the self-inflicted immolation of his personal brand. This is not going to end well.

In this particular case, there's someone whose most precious moments are their breaks during the day, and rather than saying "good on them for finding a way to do the thing they are most passionate about" the response is "gee they should have used that extremely limited free time to.... have the most shallow of conversations"?

Pleasantries are fine, but that was never going to be a long term solution for him. He needed a space that was always available to him, where he is always welcome. For better or worse, that's not the site office. (Even if it worked on that job, you don't stay in one place as a contractor)

That representation of a Sudoku is elegant, but I think it is not the most natural representation. The base constraint programming style will use a variable per square with domain 1-9, and then 27 all_different constraints. This representation is a lot closer to how people talk about the rules of Sudoku, which in my mind makes it more natural.

A full MiniZinc program would look like this

int: n = 3; int: s = n*n; set of int: S = 1..s; array[S, S] of opt S: puzzle; array[S, S] of var S: board; % Sudoku constraints constraint forall(row in S) ( all_different(board[row, ..]) ); constraint forall(col in S) ( all_different(board[.., col]) ); constraint forall(r, c in {1, 4, 7}) ( all_different(board[r..<r+n, c..<c+n]) ); % Set up puzzle constraint forall (r, c in S where occurs(puzzle[r, c])) ( board[r, c] = puzzle[r, c] ); solve satisfy;

And an instance file looks like this

puzzle = [| 9, <>, 8, 1, <>, <>, <>, <>, 4 | 1, 2, <>, <>, 8, 6, <>, 5, <> | <>, <>, 7, <>, <>, <>, <>, 1, <> | <>, 8, 3, <>, <>, <>, <>, 6, 9 | 7, <>, 6, 8, <>, 3, <>, <>, <> | <>, <>, <>, 4, 6, <>, <>, 8, <> | <>, <>, <>, <>, <>, 1, <>, <>, <> | <>, <>, <>, <>, <>, 4, 5, <>, 1 | 5, 4, 1, 9, 3, 8, <>, <>, <> |];

This is, quite literally, the silliest thing I may have ever read.

Cool, cool. Work for 30 years, save up and have say $3M to retire on, based on stock market at an all-time high. You're not a robber baron or investment banker, just someone who worked a long time and saved and invested. Govt takes $1M away from you, you have $2M now. Market drops 25%. Now you have $1.5M.

Congrats, your "plan" resulted in someone like that having HALF of everything they saved up just gone.

Yeah, yeah, I know, "if you have $1.5M you don't NEED any more money." Sounds like something that only someone with something less than $1.5M would say.

You don't "need" your iPhone, or your flat screen, or whatever. The government should not be in the business of determining what you "need" and taking the rest.

I think is really interesting how it's often suggested Waymo is at a disadvantage over Tesla due to its reliance on LIDAR and the costs associated with it. But the reality is that it's enabled Waymo to move faster and gain significant more operational experience than Tesla, and that's far more important than front loading with cost reductions in a service business.

Tesla have been operating as a product business, and cost reduction of that product was key to scale and profitability. I completely understand why they have focused on optical sensors for autopilot, lidar was always going to be impossibly expensive for a consumer product.

Waymo on the other hand have always been aiming to build a service business and that changes the model significantly, they need to get to market and gain operational experience. Doing that with more expensive equipment to move faster is exactly what was needed. They can worry about cost of building their cars later, much later.

> Is it still bad if the farmer gets replaced?

A farmer is an owner of a farm. To replace the farmer you would have to completely eliminate the entire concept of human ownership that we hold. Socialist or other community ownership structures around farms wouldn't do as that would not replace the farmer, it would make everyone a farmer.

> society benefits from its automation

Economies benefit from its automation. It's far less clear if societies benefit. Farm work is hard, but there is a sense of accomplishment when it is done, which is good for the psyche. The never ending "bullshit" jobs that most people seem to find themselves in nowadays has not lead to happiness.

S2 is attractive, but the corpus of use cases outside the Pokemon Go community is quite small. The sheer number of companies and hobbyists using H3 for analytics across a wide spectrum makes it much more attractive than S2. H3 functions are built directly into Snowflake DB for example, and h3 extensions / plugins are widely available. I tried and tried to use S2 in my company but the lack of available use cases and examples made it tough to adopt.

Do you actually not understand or is this a political quip? If you spend any time around normal Americans its really not surprising. Having thousands of soldiers stationed for a decade+ over seas in a war zone in a war of attrition with no real objective, is seen as very different than "bomb the commies bringing drugs into the country". US people are really anti war, very pro bombing communists, terrorists, and drug cartels. One puts American soldier's lives at risks, one doesn't. Go to your local working class dive bar and talk politics for an hour and it should clear up why this is a very popular move, but being in Afghanistan isn't.

Dancing links is a very cute data-structure for a backtracking search, but there are a lot more aspects of writing a good Sudoku solver than just having a good data-structure for backtracking. Propagation (making deductions), heuristics, learning, parallelism, restarts, no-goods, ...

While 9x9 Sudoku problems are trivial to solve for more or less any program, 25x25 Sudoku instances are quite tricky and a simple and fast but naive search for a solution can easily take hours.

I can’t explain the parents pressuring themselves.

if you look at any tier one city’s job centers unless you have a great career, living in a comfortable home near your house just isn’t affordable on a regular person salary.

Which means your kids spend more time in their car and less time parenting their kids.

Many families, especially ones that were careful with their spending, will choose to support their kids and enable them to live in neighborhoods. They couldn’t normally afford on their lower income.

Isn't the lesson from the success of TSLA, that you don't compete on price? That's what made Tesla the first successful EV. Because unlike the rest, they didn't try to compete on price and offer a mass market consumer vehicle. Instead they started with a roadster and then a luxury saloon both targeting the upper end of the market. I don't see the point of a budget taxi car. After all even the human driven counterparts tend to be higher end luxury saloons or SUVs.

Real question about those two women with over 1000 matches: Why don't top quality men approach them in public? It is weird they are on the apps. If you are a 7 or above, high quality men are constantly approaching you, to the point of annoyance. Or do they use the apps to find a simp/sugar daddy to pay for their dinner and lifestyle?

From this article, Tesla crashes 50% more often. But hard to compare when one has a human safety driver and the other does not.

> the report finds that Tesla Robotaxis crash approximately once every 62,500 miles. Waymo vehicles, which have been involved in 1,267 crashes since the service went live, crash approximately every 98,600 miles. And, again, Waymo does not have human safety monitors inside its vehicles, unlike Tesla's Robotaxis.

I've been asking for independent analysis for years now. The data is there. Yet all the headlines are from people who have an obvious bias - this is the first where I've seen a headline where there is no evidence that the data has been looked at.

There are many ways to "lie with statistics". Comparing all drivers - including those who are driving in weather self driving cars are not allowed to see - for example. there are many others and I want some deep analysis to know how they are doing and so far I've not seen it.
Ask HN: Need a hand with an active AI project?

Morning HN!

If you're in need of a hand on your active AI project/company, I'd love to see how I could help. 15+ year developer.

I'm starting a new AI client-work company, and want to dive into a few different domains.

It should go without saying, but everything created would be your IP, and I would be doing this for free. I work in Central Time (Austin, TX), so think a team located -2 or +1 timezone-wise would work.

Let me know what you need help with, and I'll respond back if it's a good fit!

All of the four crashes mentioned are low to no speed crashes.

At least two, to attestation of another person, was because an inattentive SUV hit the back of the car when it was making a left turn. People really want Tesla to not be good at self-driving.

https://old.reddit.com/r/SelfDrivingCars/comments/1ojjz5u/te...

None of these crashes occurred at higher than 8 MPH.

But yeah, let's not mention Waymo crashing into stationary objects and doing dangerous maneuvers such as cutting opposing traffic off during left turns or making turns from the middle lane despite having like 8x more sensors than Tesla does and pre-trained mapping

I used to travel for work (ending with the pandemic in 2020) so I've been to hundreds of distinct AA meeting groups. I would say at that point it was probably still 80%+ of meetings using at least one christian prayer, usually the lord's prayer.

In big cities you can definitely find ones that are more careful about the higher power language but they are still a small minority and so for example if you're newly sober and trying to hit meetings every day, or at odd times, they may not meet all your needs. And if your city is big enough to have a lot of meetings like this and you want them, it probably also has smartrecovery groups which are likely a better fit for a more secular person anyway.

The really interesting thing is finding the little pockets where they're catering to a different community that is a local majority. I've said traditional jewish prayers at AA in skokie il, muslim ones in dearborn mi.

But regardless of your personal higher power, sincerely doing things like "turning your will over to" it or "asking [it] to remove your shortcomings" is religious practice, straightforward, no question. Some people are simply not interested in this at all, no matter how disconnected from any specific tradition.

Social democracy is a Socialist philosophy and has been ever since the spring revolutions of 1848.

You seem to confuse capitalism with market economy. Germany's social market economy was conceived as an alternative to capitalism; a market economy with strong focus on unions and social fairness/justice. In other European countries is very similar.

Socialism core principles have always been égalite, solidarity and democracy. It's pretty silly to think that a highly hierarchical, unjust and undemocratic system has anything to do with Socialism.

Hint; it doesn't. It might say so on the marketing material ("Socialist Republic!") but that's just that - marketing to fool the numbnuts.

I bought a while back a calibration device and calibrated my displays.

I always buy good displays (ISP, high resolution, good test results) and the calibration was very very good out of the box. I sold the calibration device after.

If you don't have to provide pin point accuracy from display to the industry level printer with color profile, you will not need this if you don't buy cheap.

I think a hidden problem even if we solve memory is the curation of what gets into memory and how it is weighted. Even humans struggle with this, as it's easy to store things and forget the credibility (or misjudge the credibility) of the source.

I can envision LLMs getting worse upon being given a memory, until they can figure out how to properly curate it.

Right after the nano maintainer got bullied out by the FSF, I noticed two bindings got their defaults changed. They never change. I almost feel like it was graffiti, a flex against the old maintainer, a retribution for not doing whatever the FSF wanted.

Since forever, GNU readline programs and nano had identical bindings. I'm fast moving around the CLI because I'm fast at nano. Emacs has the same defaults. What sane organization only abandons their own defaults and prioritizes that work after pushing the existing maintainer out (or irritating them enough to accomplish this)?

Honestly, this approach would probably get you fired eventually for non-coop behaviour in every company I’ve worked at.

AI slop code is becoming the go-to way for a lot of written code. At some point it’ll make more sense to find a solution to the problem (“how to be confident in slop code”), rather than going against the financial motives of the business owners (cut expenses, maximize profit somehow through AI). I’m not sure if it’s right or wrong, but it is what it is.

> I've met many people on my travels who went to Europe on tourist visas, got work and then got to stay legally later.

That's completely legal for some nationalities, at least in Germany. §41 AufenthV allows people from certain countries to come to Germany and apply for a visa there.

A separate paragraph allows people to convert a tourist visa to a residence permit if the reason for the residence permit appeared while they were visiting. For example, going through rounds of interviews, and being offered the job while you're visiting Germany as a tourist.

There are so many other paths, but navigating those options can be confusing.

Hi everyone, thank you for all the feedback! I want to be completely transparent about what Syllabi is and isn't.

HONEST CONTEXT:

This started as a personal learning project 6 months ago. I kept adding features as I learned, and it grew into something I thought might be useful to others. It's far from polished or complete.

I'm the first to admit: • The codebase has issues (yes, lots of AI-assisted code that needs cleanup) • Documentation is incomplete (some links are broken, sorry!) • Security features aren't fully implemented yet • Docker setup needs work (missing unified docker-compose) • Many features are still in testing/progress

I'm starting a new job tomorrow and won't have time to actively develop this for the foreseeable future. Rather than let it sit on my laptop, I wanted to share it with the community in case: 1. Others find it useful as-is for learning/experimentation 2. People want to collaborate and improve it 3. The architecture/approach helps someone building something similar

This is NOT a product I'm trying to sell or a startup. It's MIT licensed specifically so anyone can fork it, improve it, or learn from it.

LOOKING FOR COLLABORATORS:

If anyone wants to actively work on this project, I'd love that! The codebase needs: - Security hardening - Better documentation - Cleaner exception handling - Unified docker-compose setup - Local model support (Ollama/llama.cpp) - Better testing

I'm happy to answer questions about the architecture and will try to review PRs when I can, but I can't commit to active development right now.

Thanks for the honest feedback - it's exactly what I needed to hear. If this helps even one person learn something or sparks ideas for better implementations, that's a win.

If true thats seriously bad stat. You buy a car, if you drive even modestly, in 15-20 years you will end up in 3-5 accidents on average. Much worse than me with mildly less kms (0 bad accidents, 1 light, few times avoiding them via quick reactions in complex situations that most probably no current self-drive could handle well if at all, ie hearing car crashes behind the bend and breaking in advance, or few cars behind us and moving a bit further to avoid being also hit in bowling style).

> It's not clear that equating organic, and synthetic thought will have any meaningful outcome at all,

I agree! I'm saying "If we equate them, we shortcut all the good stuff, e.g., understanding", because "it may be that this tech produces what we can, but that doesn't mean we are the same", which is good because it keeps us learning vs reducing all of "thinking" to just "Whatever latest chatgpt does". We have to continue to believe there is more to thinking, if only because it pushes us to make it better and to keep "us" as the benchmark.

Perhaps I chose the wrong words, but in essence what I'm saying is that giving up agency to a machine that was built to mimic our agency (by definition as a ML system) should be avoided at all costs.

While diodes alone are not suitable for complex logic, they were instrumental on making computers cheaper in the late vacuum tube era. Vacuum tubes have fairly low reliability and short usable life so having too many of them in your computer is really bad for the cost and reliability of your system. Early transistors were not much better. They would get better over time, but cheap, reliable mass produced diodes were available long before transistors got there.

And while diodes alone cannot do it, a system with a few vacuum tubes to provide the gain and driving a whole lot of diodes made a lot of computers possible at price points that vacuum tubes alone could only dream of. An example is the hacker folklore sweetheart LGP-30, of The Story of Mel fame. 113 vacuum tubes driving 1500 diodes made for a computer that was the size of a fridge, weighed 800 pounds, drew 1.5kW and cost $50k (~500k in modern money), which made it pretty much a personal computer for the late 50's.

You're absolutely right. In hindsight, I should have either: 1. Shipped something much simpler first (just RAG + one integration) 2. Polished this to a better state before sharing

I got excited about the architecture and kept adding features. Classic scope creep. The feedback about breaking it into parts is really valuable - that would have been a smarter approach.

Starting a new job tomorrow, so I can't polish it further right now. But if anyone wants to fork it or collaborate on making it more production-ready, I'd be happy to help review PRs when I can.

Thanks for the honest feedback - exactly what I needed to hear.

I believe you could do this effectively with COBS (COmpact Bit Sliced signature index): https://panthema.net/2019/1008-COBS-A-Compact-Bit-Sliced-Sig...

It's a pretty neat algorithm from a paper in 2019 for the application "to index k-mers of DNA samples or q-grams from text documents". You can take a collection of bloom filters built for documents and then combine them together to have a single filter that will tell you which docs it maps to. Like an inverted index meets a bloom filter.

I'm using it in a totally different domain for an upcoming release in InfluxDB (time series database).

There's also code online here: https://github.com/bingmann/cobs

100% valid criticism. You're right - the setup experience is rough: - Missing unified docker-compose for frontend + backend - Redis dependency not documented - No local model support yet

I was focused on features and neglected the developer experience. That's a big miss.

I'm starting a new job tomorrow and won't have bandwidth to fix these immediately, but I'd love help from the community if anyone wants to contribute: - Unified docker-compose setup - Better documentation - Local model support (Ollama/llama.cpp)

All PRs welcome! Thanks for trying it out despite the rough edges.
