<p>Interesting that on one hand the valuation of these AI providers is based on the assumption that all code (and everything else producing digital artefacts) will be written using AI in the near future, on the other hand almost all popular open source projects fight to keep AI contributions out. Hard to reconcile.<p>Personally I'm also experiencing a bit of AI hangover after using it a lot in my own open-source projects. I find it's a bit like taking drugs (not that I have much experience with that) in the sense that in the moment I'm using these tools I feel great and powerful, writing features in a span of hours that would've taken me weeks to write by hand. But inevitably some time later I will look at the code and notice all the subtle cracks and inconsistencies the tool introduced, and despair a bit at the mess.<p>I now plan to use these tools less for extensive feature development and more for planning, debugging and narrow refactoring where I can put very strict guardrails on them. I'd still say it accelerates my work but not by a factor of 10, more like 1.5-3 (which is still a lot) given the care you need to ensure what is being built is actually good. For what I really like these tools is that I need less mental focus to do coding, but on the other hand I have this new kind of fatigue of being in a constant chat loop with a machine and trying to get it to do stuff based on natural language, never knowing how it will interpret what I write and wrote before. In that sense, these tools don't feel satisfying, it's like operating a machine where you try to push some buttons to get it to do something but the internal wiring changes all the time so you never know exactly what a given button combination will do and you have to figure it out by watching the machine and constantly adapting.</p>

<p>Corporations will be quite happy with really simple features if they're packaged right. I'm selling software that mostly does things that a good programmer could whip up in a couple of days or weeks, but what cost me most of the development time wasn't the features but all the FUD around them e.g. SSO, multitenancy, audit logs, corporate design support, ... Most enterprise software could be replaced with simple scripts and command line tools if they had this enterprise layer. I'd wager tons of SaaS is just simple open-source software and libraries behind a management layer.</p>

<p>It's quite easy to write a generic Maybe struct that performs most of the encapsulation that Rust's Maybe does i.e. allow unwrapping of the inner type through a function or handling the nil case through a switch like statement. I've never seen this in the wild which makes me think people don't care about it too much. And of course it's runtime based so no compile time guarantees, and just to preempt the expected replies I know it's not the same what Rust is capable off and Rust is of course a much much much much better language than Go.<p>Personally I do experiment with these things as it makes code more readable, it just seems adoption for generics and what you can do with them is still quite low in the broader community. That said I do not deal with null pointer exceptions much at all, and when I do it's often relatively simply to spot and fix, so for me it's not a large issue.</p>

<p>I think for mostly search-focused use case like the one presented here AI is great as you don't ask it to build stuff or invent new drugs, you just want to retrieve relevant documents with laser precision, and agents can do that.<p>I think right now I'm mostly disappointed with agents writing code as they always degrade the quality of the codebase after a while, and the same goes for writing in general which just requires a ton of editing and mostly just sounds good but doesn't have a lot of substance in the end. I think you can really tell that these systems are trained to just produce plausible streams of text, especially in longer artefacts you notice that locally the inner consistency of what they produce is great but globally it really falls apart, it's like seeing the limits of their "intelligence".<p>For search however I really like AI, it has improved information retrieval so much for me where before I had to think about which keywords to use and combine and which filters to apply, describing what I'm looking for in plain text and then having the AI find it for me feels magical. Recently I wanted to find an artist that I heard in some old episode of the KEXP runcast (a running podcast), and I didn't remember anything except that it was rap with a kind of monotone voice a fast beat and a strong accent. Googles' agent asked a few clarifying questions and after a few rounds it found the artist for me, Genesis Uwusu. That's why I think Google will win in the AI assisted search market, they just have the best integration between fast and reasonably "smart" agents and high quality search data. Claude or ChatGPT are too slow and don't have fast enough data retrieval it seems, using them for search feels quite sluggish in comparison.</p>

<p>Apple RAM prices always had quite a bit of margin though, I think they charged around 4x the going market rate per GB (that said you can't fully compare their RAM to a loose DIMM stick). I was planning to pick up a new Mac Studio this autumn, now I'll have to see if I can afford it, though I have been spending 1,000 USD on LLM subscriptions in some months so I guess even a 10,000 USD Studio Mac amortizes quite fast if it allows me to run coding models locally.</p>

<p>Everyone always wants to charge as much as they possibly can, and if SK Hynix would be the only manufacturer prices would be 10x of what they are today. Especially new incumbents will not ruin the market prices as they have the highest upfront cost and their calculation of entering the market is probably based on the high prices that can be achieved. In the long run, more competition is still good as everyone ramps up production to profit more from the high prices and at some point supply will outpace demand and prices will fall (assuming no cartel / price fixing is involved).</p>

<p>It's the ultimate power user desktop system, in my opinion it even dwarfs MacOS in terms of how you can customize it and how it looks. It left Windows in the dust a long time ago in terms of functionality and usability (not that this would be particularly hard given how Windows has been degrading over the last decade). Everything is super snappy, smooth, built-in apps like Konsole and Dolphin are super polished, Konsole runs circles around the MacOS terminal app.<p>Of course running Linux on modern hardware is still a bit fraught with errors, though it has been getting much better. I run a current gen Thinkpad X9 Aura and apart from the webcam which has fundamental driver issues on all Linux kernels everything runs really well, power efficiency is also great at around 10W, not as good as a MacBook (which I also use daily) but close enough for me, and I still prefer Linux over MacOS any day.</p>

<p>Are you sure about that? You are saying that differentially private census data couldn't be used for gerrymeandering and advertisement while non differentially private data could? Hard to believe, I'm not an advertisement or gerrymeandering expert but I would assume people running ads or cutting up districts are mostly interested in aggregate statistics i.e. they won't care about single households? And I would assume they can rely on voter files, party databases etc... And to the contrary there are reports [1] that indicate differential privacy actually makes gerrymeandering analysis more difficult or impossible. So, not really an argument for differential privacy, discriminatory action can be equally well taken based on differentially private data as the government cares about groups not individuals and groups aren't protected by differential privacy. It seems people really fundamentally misunderstand what this technique can achieve and what it won't do.<p>1: <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8494446/?utm_source=chatgpt.com" rel="nofollow">https://pmc.ncbi.nlm.nih.gov/articles/PMC8494446/?utm_source...</a></p>

<p>No, there are dozens of articles discussing the mechanism and explaining the impact it had in different areas e.g. [1,2,3]. And the release mechanism wasn't just "add noise", far from it, you may read the original paper [4] to see how intricate it was, anyone wanting to make real use the resulting data would have needed to understand that approach in detail to work with the resulting data. The report of the national academies [3] is probably the most comprehensive analysis of the mechanism and the complications it introduced, so writing "it has always been inherently inaccurate" is just wrong, this new mechanism was way worse than just introducing unbiased sampling noise.<p>1: <a href="https://www.aeaweb.org/articles?id=10.1257%2Fpandp.20191107&utm_source=chatgpt.com" rel="nofollow">https://www.aeaweb.org/articles?id=10.1257%2Fpandp.20191107&...</a>

<p>I think it should be noted that there was a lot of dissatisfaction from users of the census data as far as I know. So it's not been banned just for politicals sake or because they hate privacy... Some people I talked to in the privacy field even called the whole thing a total disaster and weren't shy to put blame on John Abowd who apparently pushed this through despite a lot of internal opposition and concerns. Not sure if that's true, but what is definitely true is that the way the data was released produced serious issues downstream as most researchers and statisticians that ingested the data weren't prepared for receiving noisy data values. Differential privacy was applied in a way such that many invariants that data users cared about weren't preserved, which was expected as it's not possible as you can't preserve all invariants and at the same time add meaningful noise to the data. The thing is, with such a differentially private data release you need to adapt all of the downstream analyses to take into account the exact mechanism the data was altered in. And since the census bureau used a very intricate mechanism that didn't just add Laplace noise to data values but instead relied on a multi-stage process that preserved some invariants but not others it was very difficult to even write routines to account for the changes being made to the data. They essentially asked of every data user to rewrite their whole analysis pipeline based on the exact disclosure mechanism that contained a large number of bespoke choices regarding which data invariants to preserve and basically produced a mix of noisy, synthesized data that was just really hard to reason about. I don't even know if there even would've been a way to do this better, but the fact is that not every small county or school district has top-tier statisticians at hand that can just read a whole monograph on differentially private synthesized census data and then hotpatch their existing analysis systems to work with that data.<p>I was a big fan of differential privacy but now I think it might be doing more harm than good, as I haven't seen a single case where it was applied successfully in a problem where it actually mattered, and it contributed strongly to discrediting and preventing a lot of work on other anonymization techniques as it was deemed the only way to preserve privacy by the research community, so showing up with enhancements to k-anonymity or any other noise mechanism not rooted in it was a sure way to get ridiculed and ignored. And it's just not a practical mechanism, even when it works for a single disclosure you always end up having to blow up the privacy budget to a ridiculous amount in order to keep disclosing statistics as otherwise you would for almost all real-world data run out of budget after a few publications.<p>So, for me it's a technique that works in the areas where it doesn't really matter (publishing highly aggregated statistics that pose almost zero privacy risk even without differential privacy) and doesn't work in other areas where it would actually matter (publishing fine-grained data about individuals or small groups). There are some niche use cases but in my view the privacy community has really overblown the importance of differential privacy by portraying it as the only way to reliably anonymize data.<p>BTW the German census bureau has an interesting approach to anonymization which they use for several decades already and so far I haven't heard of any cases of successful de-anonymization of the data, maybe the US bureau should have a look at that for their own needs.</p>

<p>Yeah Fable 5 is good but feels incremental and overhyped, also burned through my entire Cursor allowance in my Ultra plan in a single day. Ridiculous. They just want to create FOMO and appear mysterious so companies and users will feel so special for being allowed to use this model and pony up more money. After all they have to grow a few order of magnitude to pump their IPO valuation as much as possible, so I think this is just a strategy to justify their increased token pricing which starts to become absolutely insane. 10-20k per month per developer, do companies really think that's a good way to spend their IT budget? I assume 99 % of software shops wrtite run-of-the-mill web/mobile/desktop apps or some legacy backend APIs and CRUD code, you don't need a superintelligence to crank that stuff out. It sounds so ridiculous to have a model that supposedly can design biological weapons and then 99 % of users vibe code spaghetti Javascript with it. But the spice must flow!</p>

<p>Well you can just scale your AI employees up and down as much as you want. Companies already pay a large premium for freelancers just to be able to fire them on a whim, so spending 5-10k a month on something that more than doubles the productivity of a senior developer might be well worth it as you can just adapt spending based on your business needs. If you can deliver a feature that lets you write a 100k invoice with 10-20k of tokens within a month or have a senior dev crunch that out in 6 months instead I think it's clear who wins. It's all about money and the AI companies know that, they have their pricing down exactly to sit in the sweetspot where it hurts just enough that companies can still afford it but not enough that they would look for cheaper alternatives.</p>

<p>I mean even cheap keycaps won't wear out for many years for most people, so I don't think quality is a big factor. I got tons of keycaps from Ali Express which are just as good as the high quality stuff, in fact most of them are made on thre same machines...<p>So not sure if that was really the issue, people ordered keycaps because they liked the design, e.g. the Dasher MT3 set was super popular due to a similar one being used in the "Severance" show.</p>

<p>Yeah I mean we have a mechanism that can bypass AI models for log lines where we are pretty sure no PII is in there (kind of like smart caching using fuzzy template matching to identify things that we have seen before many times, as logs tend to contain the same stuff over and over with tiny variations e.g. different timestamps), so we only need to pass the lines where we cannot be sure there's nothing to the AI for inspection. And we can of course parallelize. Currently we use a homebrew CFR model with lots of tweaks and it's quite good but an LLM would of course be much better still and capture a lof of cases that would evade the simpler model.</p>

<p>This is really cool! I am trying to find a way to accelerate LLM inference for PII detection purposes, where speed is really necessary as we want to process millions of log lines per minute, I am wondering how fast we could get e.g. llama 3.1 to run on a conventional NVIDIA card? 10k tokens per second would be fantastic but even at 1k this would be very useful.</p>

<p>People with such strong beliefs can be unpleasant to work with as well. Not saying you are, but there are often considerations beyond the immediate needs of developers that dictate tool choice in a company, and I find it not great if people complain about such minor inconveniences all the time (it's ok to discuss to some degree, but not in an overzealous way). Same goes for tech stacks, frameworks etc., I avoid hiring people that express extremely strong views (e.g. "JS is utter garbage") as they tend to be difficult to work with since they drag the team down with endless tech stack discussions and make others feel bad/inferior.</p>
