1) Cool, but when are they actually going to drive my car for me?

2) Any semblance of American technological superiority is pure fantasy at this point. The only area where Americans are truly "advanced" is in selling overpriced SaaS products. There are dozens of Chinese startups with robots just like this—as seen at CES—yet Boston Dynamics is still treated like it’s some untouchable, DARPA-level tech.

3) A lot of this comes down to cost: you can either hire one American fresh grad or a Chinese PhD for the same price.

3) The second reason is cultural: Americans tend to buy solutions, while the Chinese prefer to build them. Even SMEs in China maintain internal dev teams to build custom software for the business, as opposed to paying Salesforce for what is essentially a glorified Excel sheet with sprinkles of automation.

4) America is facing its own innovator's dilemma. The country is currently being run by MBAs and salespeople focused on extracting every last dollar from the consumer instead of providing real value or innovating. Perhaps we're one step beyond the innovators dilemma. The innovators are dead and we are in the corporate greed stage.

5) Americans are completely oblivious to how advanced China has become because of the propaganda they're fed. My personal "aha" moment was when Chinese EVs hit my local market and completely obliterated legacy automakers on both features and price. The American "free" (lol) market is being guarded by politicians but that won't work for long.

I tried streaming with icecast2 during pandemic and always got dropped connections in tens of minutes. It drove me mad. And it's impossible to detect in advance, receivers skip for seconds till new connection is made. From packet captures it appears as dropped ack packets. It was https so copyright filters are unlikely.

Are there different solutions, different protocols, ideally supported by browser in some simple manner? Is streaming over websocket possible?

>These programs were largely about ensuring that American propaganda can reach people in Iran or similar places.

This. The og point of USAID wasn't AID as per the name would misleadingly let you believe, but spreading pro-US anti-USSR propaganda, and only like 3% of that program was spent on actual AID, like food and medicine for the third world, but most of it went to funding media, news and journalists across LatAm, Asia, Africa dn EE, that would push domestic support in those regions for US policies and be critical of US adversaries.

US doesn't fund "freedom" of anything out of selflessness, it funds policies that are guaranteed to benefit it over its rivals, and use the word "freedom" to legitimize it. Once those benefits no longer materialize, the funding also goes away.

It was chaotic as always.

Poor corporate planning and execution is a long time Portuguese tradition. It seems our history is written by a few people that somehow emerge from that chaos and manage to put everyone else moving on some direction. Much of the lands overseas were left on their own, abandoned. There was an effort from their side to remain Portuguese because of family ties.

Brazil was different from the start. It was the chance to build a kingdom on a paradise without poverty and the problematic european neighbors. It shocks me to see the old brazilian cities with the same traditional architecture as seen on european portugal but placed in gorgeous locations. When I see those pictures, I understand why so many preferred to stay in Brazil.

Also, Brazil always had a strenght of its own that surpassed anything else seen before. Ships were larger and stronger when built there, population had a level of energy and optimism that surpassed the european counterparts. It was not a surprise when it became the heart and capital of the empire itself.

Just as curious note: Up to this day the spanish have much more respect for the portuguese than vice-versa. I was curious about why it happened that way, one day a old spanish told me something I didn't know: "it's because if we upset they portuguese they'll invade our land and burn Madrid again".

I never knew the portuguese had done such a thing, it isn't mentioned in school nor in popular culture but it did happened. Turns out this was during the wars against Spain, an army group from Brazil arrived to defend Portugal but more than just defending they went straight to the capital and subjugated it completely. This left such an impact on the self-esteem of the spanish that they haven't forgotten to this day. Brazil is indeed something else.

Um abraço deste lado do Atlântico.

> Token prices have literally gone up, where are you getting this information from.

I said like for like. You can't compare GPT5.2 tokens with GPT3.5 tokens. They're different products.

You can run local AI models today which can compete with early chatgpt releases for a fraction of what those models cost to use at the time. Thats the claim I'm making.

I have a 3rd generation iPad from 2012 [1]. The battery is still very decent after 14 years. It has a retina display and a remarkably good speaker, so I use it for e-books / audiobooks, podcasts, music (on device) and sometimes playing around with synth apps (nano studio).

The bad stuff:

- iOS update with the parallax effect (iOS 7, I think) came soon after this iPad was released and made the device feel extremely sluggish (even with effects disabled). I was very pissed (downgrade not possible). It's on iOS 9 now, still as slow. The apps I still use work ok, but switching between them is a terrible experience.

- Can't update iOS any further. Can't install any new apps. Certificates expired, so can't use any webbrowser anymore (no https) and a few months ago even podcasts stopped downloading (books and music I upload via cable).

Notice how the good stuff is all hardware, while the bad stuff is all software.

9front went further; you don't need to care about TTY's and PTY's any more except for the 'vt' tool which was made OFC to connect to Unix terminals and to run some legacy software thru APE/NPE (minimal POSIX compat modules).

The core concept of Unix weren't the terminals, but text, pipes and the orthogonal composability. rc under 9front doesn't need a terminal emulating some DEC hardware crudely. You get a shell not bound to sizes. Scripts run in the same way, but with superior editing capabilities.

Everyone agrees that most of the possible shuffles become impossible when a CSPRNG with 256 bits of state is used. The question is just whether that matters practically. The original author seems to imply it does, but I believe they're mistaken.

Perhaps it would help to think of the randomization in two stages. In the first, we select 2^256 members from the set of all possible permutations. (This happens when we select our CSPRNG algorithm.) In the second, we select a single member from the new set of 2^256. (This happens when we select our seed and run the CSPRNG.) I believe that measurable structure in either selection would imply a practical attack on the cryptographic algorithm used in the CSPRNG, which isn't known to exist for any common such algorithm.

Some years ago, I also started to have problems due to mouse use.

I experimented with alternative pointing devices. For a few years I have used trackballs. The change from mouse to trackball was good, but that still was not an optimum pointing device.

Eventually I have settled on replacing mice with small graphic tablets (Wacom Intuos S), configured in the "Relative" mode, instead of their default "Absolute" mode. The tablet is not bigger than a traditional mouse pad, so it does not take more space on the desk.

In this mode the tablets behave exactly like mice, but they are much more comfortable and also faster and more accurate. The comfort is due to the fact that you hold the extremely light stylus in a natural hand position and moving it to reach any point on the screen is instantaneous and effortless (even when only the fingers are used, without moving the hand). Moreover, touching the tablet instead of left click is also a more natural motion. The stylus is so light that I can also touch-type while keeping it between fingers, which speeds up the transitions between keyboard and pointing device, in comparison with a mouse that must be grabbed first.

Thus all my hand and arm problems have disappeared, regardless how many hours per day I use the pointing device.

¡Quick reminder! We are in the golden era of big company programming agents. Enjoy it while you can because it is likely going to get worse over time. Hopefully, there were will be competitive open source agents and some benevolent nerds put together a reasonable service. Otherwise I can see companies investing in their own AI infrastructure and developers who build their own systems becoming the top performers.

This is the VC funded startup playbook. It has been repeated many times, but maybe for the younger crowd it is new. Start a new service that is relatively permissive, then gradually restrict APIs and permissions. Finally, start throwing in ads and/or making it more expensive to use. Part of the reason is in the beginning they are trying to get as many users as possible and burning VC money. Then once the honey moon is over, they need to make a profit so they cut back on services, nerf stuff, increase prices and start adding ads.

Why would China do that?

They know they are next on the chopping block.

They need Russia to guard their back, the last thing they need is a USA-friendly regime in Russia.

You are all talking about 'just a bit longer and Russia will implode'.
Look at the state of Ukraine, who is going to implode sooner, Russia or Ukraine?

Heck, look at the state of Europe and USA! USA is a political nutcase, and Europe has deep divisions and is overflowing with incompetence and impotence. Plus enormous debts, both in USA and in Europe.

As European faced with similar pain points, I would assert it was having those MBAs offshoring everything with a colonial attittude, as if the nations on the received end would only take orders from their masters and not learn to master the technology themselves.

After a while, naturally the locals would buy the white label products that are anyway the same as the branded ones, many times produced on the same factory lines.

My father used to say, every company goes downhill when management takes over, meaning those straight out management schools without any actual business experience on what the company does, and he was kind of right, that is how we hand landed in late stage capitalism and entshitification, in the middle of geopolitics turn over.

These robots might not drive the car for us, but certainly will become part of some police containment unit, regardless if they are remote controlled or AI driven.

Hey, I appreciate your views (both positive and negative). There actually is a bit of a back story behind it all. I spent a month working on a different version of rebrain, (still available here: https://dev.rebrain.gg). After putting that work in I started to show it to some friends. It was clear from how they responded that it was not as promising as I had hoped. I listened to their feedback and came up with a different idea for LLM-based education (which is the version that's live now). I did vibe code it in about 3/4 days. But I vowed to try to get feedback sooner rather than later, which is why I posted it on ShowHN pretty early in its development. I do want to improve it... so please let me know if there are things which really frustrate you.

In my experience it is worse with clang that even more aggressively uses UB than GCC to optimize (and Chris Lattner in his famous blog post very much justified this line of thinking), and I have seen similar things with MSCV. I do not know about the others.

I think that GCC changed a bit in recent years, but I am also not sure that an optimizing compiler can not have the same policy as the kernel. For the kernel, it is about keeping API's stable which is realistic, but an optimizing compiler inherently relies on some semantic interpretation of the program code and if there is a mismatch that causes something to break it is often difficult to fix. It is also that many issues were not caused because they decided suddenly "let's now exploit this UB we haven't exploited before" but that they always relied on it but an improved optimization now makes something affect more or different program. This creates a difficult situation because it is not clear how to fix it if you don't want to roll back the improvement you spend a lot of time on and others paid for. Don't get me wrong, I agree the went to far in the past in exploiting UB, but I do think this is less of a problem when looking forward and there is also generally more concern about the impact on safety and security now.

The concept of an XTerm it's far inferior to Emacs either as a REPL with a shell (eshell), the scratch buffer of the whole Elisp environment. Ditto with 9front with remote mounts and device binding. When you can use a remote component you can do NAT by importing /net in the spot from a remote machine. When you import /proc from another one you can suddenly debug processes of another machine.

Acme with shells are still far superior too. I can edit and script the editor's content and panes and run scripts on them. I can reuse Acme as a Mail, Usenet and maybe Irc client on the spot. I can cut, copy and paste with a mouse faster than a keyboard and yet maintain the Sam commands which are like the ex/ed ones but easier for some tasks (recursive searchs) without getting yourself mad with classic regexps. Heck, I can run filters a la vi under Acme but without being bound to a terminal and thus worried about the input/output on pipes.

Interesting thing though, in some pretty extensive testing I've found that two versions of the same plugin[1] get very different opinions on sound quality depending on whether or not I use the skeupmorphic interface or a "flat" one drawn with normal toolkit graphics (I don't have a screenshot but think in terms of Ableton's vector graphics knobs).

Almost everyone seems to think the one with "real-looking" knobs and front panel "sounds better", "sounds more like the real synth", "has better filters" and so on than the flat design one, even though the DSP code and control ranges are identical between the two.

If you don't want to use knobs, what would you use instead?

Yep. I had the same experience. Except for me, it was someone I've never heard of read before, so I was none the wiser and assumed it was real. 30 minutes in I go "man this guy is really shit there's no way he should have this much credit" and I check the description and it says the same "based on X".

>Android

Drawterm, for sure. It should be under FDroid. On 9p itself, check termux.

> When I use terminal emulators, SSH, and tmux, I can switch between different clients with different resolution, pixel density, and screen orientation and have the text display acceptably on each (minus text reflow for history, which is an issue)

Oh, I understand. But you can set the font= environment variable before launching a tool and choose your own font for that window/tool. For instance, you can run sam with a totally different font than rio windows.

I have been testing it.

Verdict: Generates generic bland slop proficiently. Very strong inclination to generic pop, no matter how instructed. Is way behind other music generators. Very similar to when first AI music generators appeared, but with better sound quality.

I'm sure Gemini will improve quickly. They launch these early to test with users.

Yes, the autonomy level of these robots was what I was yesterday emailing with my former colleagues we were wondering. Two months ago CNET & PC-Mag posted following video which suggests more about robots movements being assisted by humans. And it also shows Chinese have being edge of the development at that point.

https://www.youtube.com/watch?v=jXTibM33SDg

However, then another short video bit alike popped up and is puzzling too.

Apparently Unitree robot is playing pingpong match like a pro. Sorry about german announcer, I couldn't find with english.

https://www.youtube.com/shorts/BgD1ukTyNnw

There is another match viewable by pressing that "Robot plays ping ppng #robot" arrow.

How about that robot? Is it human assisted or not? Our opinions diverted, I'm quite sure it is assisted but my former colleague thinks it's got to be autonomous as it would be too difficult and slow to do that fast movements with remote control assisted robot.

It would be nice to hear opinions about that playing robot too if anyone could provide some insight in that.

edit: I think the serve waiting robot hand movement and after losing wiping left eye gesture as a disappointing a bit in my opinion gives up it's human. Or if not, why would a robot do such a human like gestures.

edit2: OK, good points, I see now. It's definitely a fake. Thanks to all who replied :)

Thanks for your comment, I assumed that Beeper uses the DMA API [1], but I couldn't find if they really do, or they are just faking requests "like from official app". It seems the latter is true since it shows my chat history and DMA does not include that.

How We Built NxCode with LLMs

We believe in being upfront about our development process, especially since NxCode is a tool designed to harness the power of AI for others.

NxCode itself is a hybrid. The core platform architecture, our proprietary nxcode-sdk (handling auth, billing, and payments), and the orchestration engine were hand-coded by our engineering team to ensure security, stability, and performance. However, we heavily utilized LLMs (specifically GPT-4 and Claude 3.5 Sonnet) during development to accelerate writing boilerplate code for frontend components, generating test cases, and drafting documentation.

Crucially, the output of our product—the code it generates for you—is 100% AI-driven. Our goal is to prove that LLMs, when wrapped in a robust, human-engineered framework, can produce production-grade, revenue-ready software, not just prototypes. We use AI to build the tool that helps you build with AI.

Unfair reading bordering with propaganda.

On one hand Boston Dynamics showed similar skill robot well before this demo, only without coreography, which is were most of the wow effect comes from here.

https://m.youtube.com/watch?v=UNorxwlZlFk

Heck check were they were 5 years ago

https://m.youtube.com/watch?v=fn3KWM1kuAw&pp=0gcJCUABo7VqN5t...

Things is american research is financed by outcome potential not for grandstanding, and free standing robot that can only do recorded coreography aren't that useful outside factory floors, and factory floors can use ceiling rails or wheels to better effect.

So yeah video is suler cool, but there isn't much to it beyond that to read in terms of capabilities. You seem just to be projecting what the truth you want to be on top of a funny dance.

> So don’t allow accounts with ages set below the limit like they already do for under 13s. Why does this translate to every other site wanting my government ID or a scan of my face?

Because self inputed age fields don't work. People just lie to access what they want.

You have to understand that the goal here is not token compliance but actually limiting teenagers exposure to something we now know to be highly addictive and damaging to mental health.

Clearly, the market is not able to self restrict and will exploit every opportunities given to it. It's only logical to take stronger restriction. That's basically bringing regulations on social media on the same track as tobacco and alcohol.

Personally, I think it makes a lot of sense.

Definition of "high status" vary by demographics.

Some want to carry X sportswear with prominent branding, others take pride in high-price tag items without any explicit branding.

The "I identify with this athlete", "I identify with this musician", "I dgaf what you think of me" groups probably don't intersect much, with brands and offering catering to these and multiple others...?

I used to be able to google a question like that and get an accurate answer within the top 3 results nearly every time about 20 years ago. Then it got worse and worse and became pretty much completely useless about 10 years ago.

Now AI will give me a confident answer that is outright wrong 20% of the time or kind of right but not really 30% of the time. So now I ask something using an AI chatbot and carefully word it so as to have it not get off topic and focus on what I actually want to know, wait 30 seconds for its long ass answer to finish, skim it for the relevant parts, then google the answer and try to see where the AI sourced its answer from and determine whether it misinterpreted/mixed up results or it's accurate. What used to be a 10 second google search is now a 2-3 minute exercise.

I can see very much how people say AI has somehow led to productivity losses. It's shit like this, and it floods the internet and makes real info harder to find, making this cycle worse and worse and take more and more time for basic stuff.

#4 is the biggest problem, by an overwhelmingly wide margin. Solve that and everything else fixes itself more or less instantly. Everything is now about money and extracting every single penny possible, instead of about actually achieving things. Even most 'entrepreneurs' are now just starting businesses primarily with the goal of selling them. Everything is broken, because of the pursuit of money became the goal, further compounding by everything being run by people who have no skills except the pursuit of money.

Money should be a means to achieve a thing, not the goal in and of itself. I think the most visible decline came with the increasingly overt goal to charge rent on friggin everything. That's simply not a sustainable or realistic economic model for society and consequently even if it might maximize corporate income in the short to mid-term, in the longterm it's equally catastrophic for them as well.

GUID / UUID v5 is a name-based identifier that generates deterministic GUIDs / UUIDs by hashing a namespace UUID and a name using the SHA-1 algorithm. The same namespace and name combination always produces the same GUID / UUID, making it useful for stable, repeatable identifiers derived from existing data. V5 is the modern, preferred alternative to v3, which uses the weaker MD5 algorithm.
