> What breaking changes has Rust made "on a whim" ?

I don't know about "on a whim", but this isn't far off in regards to breaking compatibility. And it caused some projects, like Nix, a lot of pain.

I feel bad about the quantum guru, elder of the quantum village. He starts of his talk by complaining that people assumed "we would have 10 to 20 years" when news about quantum computing hit. The quantum computing hype was 10 years ago. Microsofts attempt to sell people the Quantum computing cloud with Q# is already 8 years old by now. The people who said we had at least 10 years were right. Guy is in denial either about his age or how much of his life he spend trying to sell people on second hand hot air.

It's honestly a shame that comments from people like you will be silently forgotten, when your unending ceaseless discharge of excuses to sweep the rug for the current status quo should be something that you should never be allowed to forget. I guess you have a point though, a flame left unextinguished will only grow and that was the result here. Not too many outcomes remain when you only add more fuel, but there is always another way to solve that problem :)

> I am reminded how thankful I am that AI is around now, because it understood what you clearly don't.

We understand what you're saying just fine but what you're saying is simply wrong as a matter of technical fact. All of that context still exists and still degrades the output even if the model has fooled you into thinking that it doesn't. Therefore recommending it as an alternative to actually clearing the context is bad advice.

It's similar to how a model can be given a secret password and instructed not to reveal it to anyone under any circumstances. It's going to reject naive attempts at first, but it's always going to reveal it eventually.

In which situation does the end user not pay for everything? Even a fine or a tax on a company ends rolled up in the price paid by the end user. Same thing with programs paid for by the government. It’s the taxpayers who foot the bill.

I’m kinda split on the whole Apple situation. I’m firmly in the camp of “monopoly bad”, but apparently people are fine with apple’s practices. It’s not like they have to buy an iPhone.

Interestingly they don't tell you anything (unless I missed it) about the battery for the non-plugin hybrids, eg. the Corolla Cross: https://www.toyota.com/corollacross/features/mpg_other_price...

I was looking up this year's Corolla a while ago and likewise there was minimal info that I could see about the battery capacity, which I think I figured out was about 3kWh.

Likewise, I still use a physical one at home and at my workspace. However, I always find myself resorting to the digital version when trying to jot down ideas and checklists while discussing my work at the office (my colleague's desk or in the meeting room) or even grocery shopping.

As much as I love the digital one, I find this digital version quite useful for one time notes or checklists, while still being able to find them later in the archive.

That era sucked for sure, but since (I think) 2021, macbook pros have magsafe, 3x USB-C, an HDMI port, and an SD card. I had a 2014 MBP I was waiting to upgrade once they came up with a sensible redesign, and I'd say they did!

I still have my 2014, along with a 2021 MBP for work, and still love them as machines for my usage profile - writing software/firmware, and occasional PCB design. The battery life is good, M-series performance is great, screen is decent-to-good, trackpad is still best in class, and macos is _okay_ in my book. The keyboard isn't amazing as I prefer mechanical for sure, but I still type faster on a macbook keyboard than anything else. That being said, I designed a mechanical keyboard that sits on top of the macbook keyboard so I can enjoy that better typing experience.

Pretty dang happy with my setup.

At computerenhance.com[0] Casey Muratori shows that memory mapped files actually perform worse at sequential reads, which is the common case for file access.

That’s because the CPU won’t prefetch data as effectively and has to rely on page faults to know what to read next. With regular, sequential file reads, the CPU can be much smarter and prefetch the next page while the program is consuming the previous one.

Yes, my understanding is:

- finding patterns in data is memorization

- finding patterns in metadata is intelligence

- finding patterns in meta-metadata is invention

For example, if you ask someone to hang a painting in an art gallery 12 feet from the floor using a 13-foot ladder:

- a worker will use the safety rule of staying 5 feet away from the wall. This is what GPT-3 does. [1]

- an engineer will apply the Pythagorean theorem. This is what o3 does.

- Pythagoras, seeing it for the first time, will derive the theorem. GPT-5 is nowhere close to that.

This climbing up the ladder of abstraction existed even before LLMs. DeepMind's AlphaGo learned from human games. But AlphaGo Zero and AlphaZero trained entirely through self-play and began uncovering new strategies across Go, chess, and shogi. So whether it's code, a game, or pseudocode, they're all metadata operating at the same level of abstraction.

> There is a possibility of collisions in the future, we can use the reserved flags as a nonce for known collisions if this ever comes up.

This is a ticking time bomb. Good luck getting folks using this standard to implement this properly when this eventually happens. If this is the contingency for a collision, then a massive non-hash-based list of every combination was probably a better solution to begin with.

Edit: On second look, I'm not sure if binmoji is working properly? The component hash lookup table seems way too short to cover even a fraction of possible combinations, and it doesn't seem like it can properly roundtrip emojis such as this diverse family emoji: https://apps.timwhitlock.info/unicode/inspect?s=%F0%9F%91%A8...

A different thread mentions "what if you take a photo of an AI photo with the Roc camera?" - I still think that would be hard due to perspective, lighting, various other artifacts.

Scanning an image would be much easier to dupe though - scanners are basically controlled perspective/lighting environments so scanning an actual polaroid vs an ai generated polaroid printed on photo paper would be pretty indistinguishable I think.

I am actually willing to support DIY camera efforts, but if you're semi-serious about taking pictures, this just wouldn't work. First, Raspberry Pi (I'm guessing this is a CM4/CM5) is a disaster for a camera board. Nobody wants a 20s boot every time you want to take a picture, cameras need to be near instantaneous. And you can't keep it on either, because the RPi can't really sleep. There are boards that can actually sleep, but with fewer sensor options.

Now moving on to the sensor (IMX 519 - Arducam?) - it's tinier than the tiniest sensor found on phones. If you really want to have decent image quality, you should look at Will Whang's OneInchEye and Four-thirds eye (https://www.willwhang.dev/). 4/3 Eye uses IMX294 which is currently the only large sensor which has Linux support (I think he upstreamed it) and MIPI. All the other larger sensors use interfaces like SLVS which are impossible to connect to.

If anyone's going to attempt a serious camera, they need to do two things. Use at least a 1 inch sensor, and a board which can actually sleep (which means it can't be the RPi). This would mean a bunch of difficult work, such as drivers to get these sensors to work with those boards. The Alice Camera (https://www.alice.camera/) is a better attempt and probably uses the IMX294 as well. The most impressive attempt however is Wenting Zhang's Sitina S1 - (https://rangefinderforum.com/threads/diy-full-frame-digital-...). He used a full frame Kodak CCD Sensor.

There is a market for a well made camera like the Fuji X-Half. It doesn't need to have a lot of features, just needs to have ergonomics and take decent pictures. Stuff like proofs are secondary to what actually matters - first it needs to take good pictures, which the IMX 519 is going to struggle with.

This provides a continuous revenue stream that allows maintenance and improvement of the game without affecting gameplay. It's entirely cosmetic. Don't participate in it if you don't want to. I played with stock skins majority of the time till a friend gifted me an AWP Redline after staying at my place. It was cool but to someone who just wants to enjoy the game it hardly matters. Besides you can go to various private servers and play with whatever skins.

I make heavy use of the "temporary chat" feature on ChatGPT. It's great whenever I need a fresh context or need to iteratively refine a prompt, and I can use the regular chat when I want it to have memory.

Granted, this isn't the best UX because I can't create a fresh context chat without making it temporary. But I'd say it allows enough choice that overall having the memory feature is a big plus.

The very existence of dark matter is postulated by us based on those very laws of physics that include the speed-of-light limit as a foundational axiom. If general relativity is not really true, then there's no basis to infer the existence of dark matter from our observations.

But it could also be something like https://en.wikipedia.org/wiki/Modified_Newtonian_dynamics.

Honestly it feels weird to call these features "memory". I think it just confuses users and over encourages inappropriate anthropomorphism. It's not like they're fine tuning or building LoRAs. Feels more appropriate to call them "project notes".

And I agree with your overall point. I wish there was a lot more clarity too. Like is info from my other chats infecting my current one? Sometimes it seems that way. And why can't I switch to a chat with a standard system prompt? Incognito isn't shareable nor can I maintain a history. I'm all for this project notes thing but I'd love to have way more control over it. Really what makes it hard to wrangle is that I don't know what's being pulled into context or not. That's the most important thing with these tools.

Turns out it was the GM of Trenchant who fired an exploit developer named Jay Gibson who was subsequently targeted by a nation state actor [0], and who's firing saw significant discussion on HN [1] earlier this week.

Based on the indictment, it looks like Jay Gibson may have been framed by Williams.

>Hypocrisy is the tribute vice pays to virtue, and at least to this point, the Executive Branch cannot get away with "classified" actions within the United States that can't be defended in court under the color of unclassified black-letter law.

Right so we got here eventually, you are arguing legally.

So it isnt that men in black suits dont exist (they do) its that they can be legally be prosecuted if found to be acting outside of their jurisdiction.

The issue is that law isnt reality, its not even a sideways glance at reality. People in power do things and then only regret them if they are held accountable at a later date. Which is often not the case.

It makes absolutely no difference if the guy in the black suit is a local cop cosplaying, government goons above their station, or actual black hats working illegally in the wrong jurisdiction, this shit happens.

Dont take it from me, take it from noted conservative writer Robert A Heinlein “government is a living organism. Like every living thing its prime characteristic is a blind, unreasoned instinct to survive. You hit it, it will fight back.”

So we can read the GP quote.

'In fact, the author has heard from serious U.S. SETI researchers that they are convinced that “men in black suits” will appear at their laboratory door the moment a detection is confirmed.'

As "We think we would be placed under extreme government pressure when a detection is confirmed through both legal and illegal means"

Its not the same as "SETI claims MIB is real" or anything.

Brings to mind this poem

Handbag by Ruth Fainlight My mother's old leather handbag, crowded with letters she carried all through the war. The smell of my mother's handbag: mints and liptsick and Coty powder. The look of those letters, softened and worn at the edges, opened, read, and refolded so often. Letters from my father. Odour of leather and powder, which ever since then has meant womanliness, and love, and anguish, and war.

I think you can find something similar in a modular synth: you can have an envelope generator that generates control voltage, and connect it to a filter cutoff frequency input.

I don't care much how it is made in other DAWs, I just tried to design a routing system for a DAW on a paper. I needed a concept that would be simple yet powerful. So I thought that we can define 3 types of data - audio data, MIDI data and automation (parameter) data. And every plugin may have inputs/outputs of these types. So if a plugin has 20 parameters, we can count them as 20 inputs. And we can connect inputs and outputs however we want (as long as the types match). Of course, we also have 3 types of clips - audio, MIDI and automation curve clips. And obviously we can process these data with plugins - so we can take a MIDI clip, connect it to a plugin that generates envelopes for incoming MIDI notes, and connect its output to a cutoff frequency of a filter. Why not?

Technically it is possible to process parameter data, we just have to deal with converting data between different formats - some plugins might have "control voltage" inputs/outputs, other allow changing parameters sample- or block-precise points. And here VST3, which has a defined model for parameter interpolation, is easier to deal with than plugin formats that do not define exact interpolation formula.

By the way now I noted a serious weakness in my model - it doesn't support per-note parameters/controllers - all parameters are global in my concept. Guess I need to think more.

Your point about modulating parameters is valid, however I am not sure if it is better to implement modulation in a host and have full control over it (what do we do if a user moves a knob when the automation is being played) or have every plugin developer to implement it themselves (like in CLAP which supports parameter modulation).

> This is not possible in VST3,

I think it is possible - the plugin gets a sequence of parameter changes from the host and doesn't care where they come from. As I remember, plugins may also have output parameters, so it is possible to process parameter data using plugins.

> they don't actually want to cut the budget

Eh, I would say its well-known in deficit circles that all politicians (intellectually) desire to balance the budget, but it is basically impossible. Social Security, Medicare/Medicaid, and debt servicing are such large pieces of the debt pie that the entirety of discretionary spending makes basically no impact in balancing the budget. These are de-facto untouchable obligations because too many people's lives depend on them and any party that enacts austerity will be swept out of office. Neither party will increase taxes on themselves (the rich) and taxing the middle/poor guarantees you lose the next election. The only path forward in the U.S. is basically kicking the can down the road until it implodes like so many other high debt-load western nations before them.

Thank you for the kind words! You're absolutely right - I didn't do this alone. My dad has been incredibly supportive throughout this journey, helping me learn to code and working alongside me on this project. The technical architecture and many of the hard problems were definitely team efforts.

I'm grateful to have that support system. It's easy to just consume content and games, so having someone push me to create instead has made all the difference. Your parents sound like they did the same for you - that's awesome.

Thanks for taking the time to share your experience!

There’s a market for social media that bans slop, period. I don’t think it matters how it was made.

Also, that market may not be large. Yes, people prefer quality, but (how much) are they willing to pay for it?

Fair point! I could have done a better job explaining the technical depth upfront rather than leading with my age.

What we built: persistent memory using vector embeddings (Pinecone), semantic search across conversations, Socratic teaching system, and unified workflow integration. The value isn't in the base model - it's in the architecture layer we added on top.

I should've let the technical work speak first. Appreciate the feedback.

>However, telling citizens to get fucked while taking their money and giving it to non citizens, to me, was certain to lead to violent conflict between citizens.

Whose money? Being given to which non-citizens?

Seriously. Be specific here. the words you used are all in English and are even fairly grammatical. But they don't model reality.

Undocumented folks, by virtue of being undocumented, are ineligible for public assistance of any kind, pretty much everywhere in the US.

What's more, in order to work, they need to provide an SSN and they need to use someone else's because they can't get their own -- because they're undocumented. But they and their employer must each still pay Social Security and Medicare taxes which pay for those programs -- but since they're undocumented, they'll never collect any of the money they paid into those programs in taxes.

So I ask again, specifically, what taxpayer money is being paid to which non-citizens? Please be specific here.

Agreed. I feel that a lookup table can probably map all emojis possible to a uint32 (maybe optimistically uint16, [1] says there's about 4k emojis, does that include skin variations?). And you can add new ones sequentially after so IDs remain stable.

So… I‘m not allowed to have and express an opinion about the state of affairs in the US, because I‘m from Europe?

And why doesn’t this belong here, exactly? Don’t you think it’s interesting to see how quickly all those companies rudder back their DEI stuff as soon as the weather gets a bit rough — the very same DEI stuff that supposedly was so important and central to their identity and mission just a few months ago?

Do you want to know what doesn’t belong here? Ad hominem attacks.

If you don’t share my opinion, attack me on the content of my post, not on my geographic location.

And yes, whether the US is going into the direction of becoming a fascist state or not is totally up to debate.

But I guess we can all agree: something changed since January.

And it’s interesting, and relevant data, to see which companies stand their previous ground, and which don’t.

I guess they don't have a recovery procedure for the "congestive collapse" edge case. I have seen something similar, so I wouldn't be frowning at this.

A couple of red flags though:

1. Apparent lack of load-shedding support by this DWFM, such that a server reboot had to be performed. Need to learn from https://aws.amazon.com/builders-library/using-load-shedding-...

2. Having DynamoDB as a dependency of this DWFM service, instead of something more primitive like Chubby. Need to learn more about distributed systems primitives from https://www.youtube.com/watch?v=QVvFVwyElLY

I find that extremely optimistic. It's almost as if you've never developed software.

I am curious about Waymo's testing. Even "adding a regression test" can't be simple. There is no well defined set of conditions and outputs.

Not sure if ditching infinity cache/L3 for a bigger L2 would make sense. It seems at least plausible to me that growing the L2 cache that much would make its latency worse, thus losing most of what has been gained. In the image you linked, Nvidia's L2 latency is like twice as high as AMD's!

Keep in mind that the 'big' desktop chips have bigger caches too. The L2 on a 5080 and 'L3' on a 9070 XT are both 64 MB. Additionally, AMD has already been growing the L2, going to 8 MB on the 9070 XT vs. 4 MB on the 7800 XT and 6800 XT.

They wrote the scarcity is artificial.

I'd say that's true: if you have one skin, there's virtually zero production cost to making more copies of said skin.

It's not that different for many things in the real world, I suppose (eg: if you sell way above cost, then your cost is also arguably zero), but I'd say it's magnified in the digital world (or even with NFTs).
