From the Hacker News thread>WASM vs a container runtime isn't a meaningful comparison because they're at different layers of the stack. It's not just comparing pure WASM (bytecode) but the WASM+WASI (runtime) which is what this article's WasmEdge (runtime) is about. It's a meaningful comparison when the original creator of Docker containers also compared them: >Solomon Hykes / @shykes@hachyderm.io @solomonstre >If WASM+WASI existed in 2008, we wouldn't have needed to created Docker. That's how important it is. Webassembly on the server is the future of computing. A standardized system interface was the missing link.

From the Hacker News threadI've shared this link before, showing Riley Goodside's artful prompt-crafting, but it's again relevant to this topic: twitter.com/goodside/status/15818055038…... GPT-3 is perfectly capable of recognizing what kinds of things it will be bad at, and can be encouraged to generate machine-executable queries to fill in that gap. (note this is based on prompting GPT-3, not chatGPT, but the principles about what this language model is capable of apply) It can even go one level deeper - there's an example there of it generating a python script that uses the 'wikipedia' library to look up the date of death of the Queen, as a way to fill in knowledge it doesn't have. Tell it it can use the wolframalpha module to answer questions that involve complex units, quantities, or advanced mathematics, and it'll almost certainly do that too. One of the things I love is this reply to that tweet - twitter.com/JulienMouchnino/status/1582…... "How is it possible that GPT-3 understands what a human can compute in his/her head?" Riley's quick demo prompt that shows how well ChatGPT can guess whether particular mathematical results are easy to guess matches human intuition surprisingly well.@jameshartWolfram Alpha and ChatGPT2023

From the Hacker News threadI get your point, but also on the other hand, art is subjective, and people subjectively appreciate older / imperfect versions of things. Consider film grain - it's an artifact, an unintentional or unwanted side-effect of how films used to be made. But because it was a part of a production, people wanted it back - it gets added artificially to modern films, added as filters to video games, and video encoding has special features to support it without affecting compression negatively too much. Or take video games, particularly 2d / pixelart ones - they were built for CRT displays and relatively low resolutions. They can remake them now with multiples of the original resolution and fidelity, but for many people it loses some of it. Some art doesn't translate at all - take this digitized artwork from Castlevania, which was digitized specifically for display on CRT displays but which loses all charm (e.g. the eyes reduced to a single pixel) when rendered somewhere else: x.com/CRTpixels/status/1408451743214616… But this probably applies to film as well; if a film was made for a 35mm projector from the 70's, it won't look good or anywhere near that "experience" on a modern day 4K OLED display without editing. At the end of the day I think the viewer should be given options and choices. And for a good while it looked like they would - with DVD and blu-ray offering options like different audio tracks, camera angles, and different versions of the same film in one package. But that never materialized because I suppose it's only a wish from purists. And at that point they're competing with piracy and internet hobbyists like the article.@Cthulhu_Pirating the Pirates2026

From the Hacker News threadI thought the biggest issue wasn't with the models themselves, but how Zillow decided to apply and act on them, which is why it didn't work in practice. So on average their predictions may have been pretty good, but since each transaction also depends on the other party to accept their offer, and whether they get outbid, most of their predictions where the offer actually goes through would be on the tail end of where they slightly overestimated the price. This tweet from the article summed it up nicely > Zillow made the same mistake that every new quant trader makes early on: Mistaking an adversarial environment for a random one. twitter.com/0xdoug/status/1456032851477… I was lucky to make and learn from that mistake pretty quickly with some algorithmic trading on much smaller amounts. With housing transactions being much larger and slower, you wouldn't learn this lesson until it was too late. Models never perform as well in practice as they do in theory, and you need to remember to account for both known unknowns and unknown unknowns.@elesiutaProphet: Automatic Forecasting Procedure2023

From the Hacker News threadThere's a problem when people who aren't very sensitive to latency and try and track it, and that is that their perception of what "instant" actually means is wrong. For them, instant is like, one second. For someone who cares about latency, instant is less than 10 milliseconds, or whatever threshold makes the difference between input and result imperceptible. People have the same problem judging video game framerates because they don't compare them back to back very often (there are perceptual differences between framerates of 30, 60, 120, 300, and 500, at the minimum, even on displays incapable of refreshing at these higher speeds), but you'll often hear people say that 60 fps is "silky smooth," which is not true whatsoever lol. If you haven't compared high and low latency directly next to each other then there are good odds that you don't know what it looks like. There was a twitter video from awhile ago that did a good job showing it off that's one of the replies to the OP.

From the Hacker News threadWhat you wrote about C versus C++ is largely untrue. C++ is not faster than C, even when “using library functions which use void pointers”. There is nothing about a void pointer that prevents inlining in either C or C++. There is also no “optimized on actual types” for C++ and not C, since everything is compiled into a low level intermediate language in the compiler (typically three-address code). All of the C++ types are absent at that point. The low level intermediate representation is then what receives optimization. For example, GCC will outright inline both bsearch() and the provided comparator in cases where it can see the definition of the comparator, such that there are no function calls done to either bsearch() or the comparator. C compilers will do this for a number of standard library functions and even will do it for non-library functions in the same file since they will inline small functions if allowed to do inlining. When the functions are not in the same file, you need LTO to get the inlining, but the same applies to C++. That said, I have never seen assembly output from a C++ compiler for C++ using C++ specific language features that was more succinct than equivalent C. I am sure it happens, but the C++ language is just full of bloat. C++ templates usually result in more code than less, since the compiler must work much harder to optimize the result and opportunities are often lost. It is also incredibly easy for overhead to be hiding in the abstractions, especially if you have a thread safe class used in a single threaded context as part of a larger multithreaded program. The compiler will not optimize the thread safety overhead away. You might not believe that C++ language features add bloat, so I will leave you with this tidbit: twitter.com/TimSweeneyEpic/status/12230…... Tim Sweeney’s team had C++ code that not only did not use exceptions, but explicitly opted out of them with noexcept. They got a 15% performance boost from turning off exceptions in the compiler, for no apparent reason. C, not having exceptions, does not have this phantom overhead.@ryaoMaking C and Python Talk to Each Other2025

I agree that a business, like YC, that has been around for a while, monetizes directly with a fee-for-success model, and has good reviews is very likely to be effective.

From the Hacker News threadBe cautious when using Telegram for important matters. I recently examined a situation where confidential messages from high-ranking Moldovan officials were leaked through Telegram. Unlike WhatsApp and Signal, which offer end-to-end encryption by default, protecting your messages even in case of a SIM swap, Telegram does not offer the same level of security. A SIM swap or a breach in their system can lead to message leaks. Despite advertising themselves as a "secure messaging" platform, Telegram lacks default end-to-end encryption, making it less secure than its competitors.

From the Hacker News threadUnfortunately its not very good at longer context lengths, which sort of defeats the point of efficient scaling with context. See twitter.com/arankomatsuzaki/status/1639…... Its also not really an RNN. The best way to describe the key time mixing operation is a normalized exponentially weighted moving average (EMA)- no non-linearity. Once viewed this way, its not surprising that it struggles at longer contexts- everything decays, and it has limited space to put things. Of course, it does have some clever tricks, and can choose to remember things for a while by upweighting them, but not forever.@StrawThe RWKV language model: An RNN with the advantages of a transformer2023

From the Hacker News threadTo clarify, t-SNE and UMAP are clustering techniques, not dimensionality reduction (PCA/SVD has more nuance, as the parent is hinting at but it is much more aligned with preserving relationships than other techniques[0]). Lior Pachter seems to have taken this quite to heart and this is a hill he'll die on. Linking a useful post by him[2], but you'll find many if you follow. The distinction is that dimensionality reduction is supposed to retain structure and meaningful properties of the original data. This is vague so the term is fast and loose. The important part is that you understand that these methods pressure clustering. Especially as an engineer (in any form) it is more important that you understand where techniques fail. Understanding where techniques fail is a critical component that isn't just underappreciated, but often perplexingly ignored! (talk to a physical engineer and you'll find a significant part of their job is failure analysis) What can also be helpful is looking at the t-SNE creator's webpage[1], where you'll see examples given. Look at MNIST and pay close attention to the clusters and items in them. Are clusters that you'd expect to be near one another actually? Do numbers that are similar smoothly transition into one another? The top 4/9/7 structure is good but clearly 7 should transition into 1's (if we manually look at data you'll pick up on this in no time) We can say the same about some other numbers and structures. Of course, we've reduced a 784 dimensional object into a 2D representation, so we are losing a lot, but the most important question is what we are losing and if it matters to us. This question is surprisingly frequently absent despite being necessary. One of the best ways to understand limitations is, unfortunately, to look at works that build upon the previous work. There are two main reasons for this: 1) we learn more with time, and 2) the competitive nature of publishing actively incentivizes authors to not be explicit about the limitations of their work as doing so often significantly jeopardizes the likelihood of the work being published as reviewers (have historically) weaponized these sections against the authors[3] (this is exceptionally problematic in ML (where I work, hence the frustration) and is unfortunately growing more problematic, and rapidly (hence the evangelization)). UMAP does an okay job though and I want to quote from the actual paper: > In particular the dimensions of the UMAP embedding space have no specific meaning, unlike PCA where the dimensions are the directions of greatest variance in the source data. We can also look at DensMAP[4] where we see they specifically target increasing density preservation. A critical aspect for data and local structure! We can of course attempt to dive deep and understand all the math, but this is cumbersome and an unrealistic expectation as we all have many things. But the best thing I can say is to always be aware of the assumptions of the model[5]. If there is one thing you _should not_ be lazy about, it is understanding the assumptions. Remember: ALL MODELS ARE WRONG. But wrong doesn't mean useless! Just remember that there are nuances to these things and that unfortunately they are often critical, but our damned minds encourage us to be lazy. But you can trick yourself into realizing including the nuance is "lazier," if you account for future rewards/costs instead of just immediate (a bit meta ;) I hope this wasn't too rambling... and did provide you with some answers you were looking for. [0] In the words of Poincare: mathematics is not the study of data or objects, but rather the relationships between the data and objects. The distinction may seem like nothing, but it is worth mentioning. [1] twitter.com/lpachter/status/14313259694… [2] lvdmaaten.github.io/tsne/ [3] If you are a reviewer, stop this bullshit. It is anti-scientific. Your job is not to validate papers, you can't do that. You also can't determine novelty, this concept itself is meaningless and to provide meaning needs substantial nuance (99% of the time a lack of novelty claim contains more bullshit than this statistic). You can only invalidate a work or give it in-determinant status. Papers are the way scientists communicate with one another. The purpose of a reviewer is to check for serious errors, check for readability (do not reject for this if it can be resolved! SERIOUSLY WTF), and provide an initial round of questions from a third party point of view that the authors may have not considered. Nothing else. Your job is _NOT_ to reject a work, your job is to _IMPROVE_ a work and help your peers maximize their ability to communicate. We have a serious alignment problem and for the love of god just stop this shit. Karen, I know you're Reviewer #2. Get a real hobby and stop holding back science. [4] biorxiv.org/content/10.1101/2020.05.12… [5] Model is a much broader term than many people understand. Metrics, evaluation methods, datasets, and so on are also models. These are often forgotten about, and to serious detriment. All metrics are wrong, and you cannot just compare two things on a singular metric without additional context. Math is a language, and like all languages it must be interpreted. It is compressed information and ignoring that compression will burn you, others, and your community. Similarly, datasets are only proxies of real world data and are forced upon us due to the damned laws of physics that prevent us from collecting the necessary infinite number of samples as well as the full diversity of that true data (which is ever changing). As "just a data engineer" (no need for the just ;) it is quite important that you always keep this in the back of your mind. Especially when utilizing the works that my peers in AI/ML develop. There's a lot of snake oil going around and everyone has significant pressure to add it to their works.@godelskiAlgebraic Topology for Data Scientists2023

From the Hacker News threadThe last author's tweet thread and replies have some interesting tidbits: twitter.com/Eric_Wallace_/status/162044… * "We propose to extract memorized images by generating many times with the same prompt and flagging cases where many of the generations are the same." * "- Diffusion models memorize more than GANs - Outlier images are memorized more - Existing privacy-preserving methods largely fail" * "Stable Diffusion is small relative to its training set (2GB of weights and many TB of data). So, while memorization is rare by design, future (larger) diffusion models will memorize more." * "It only memorizes a very small subset of the images that it trains on." * "our goal is to show that models can output training images when generating in the same fashion that normal users do."@saurabh20nExtracting training data from diffusion models2023

From the Hacker News threadThe thing is, it's not gibberish. A sufficiently small language model can be understood by humans: twitter.com/karpathy/status/16451156225… The explanation is perfectly sensical, just too complex for humans to understand as the model scales up. The thing you're looking for - a reductive explanation of the weights of a ANN that's easy to fit in your head, does not exist. If it were simple enough to satisfy your demands, it wouldn't work at all.@Jack000In two moves, AlphaGo and Lee Sedol redefined the future (2016)2023

From the Hacker News thread"A computer can never be held accountable, therefore a computer must never make a management decision". Or in this case, a legal one. twitter.com/swiftonsecurity/status/1385…... The accountability of the existing judicial system is already pretty thin, and in some cases being elected makes it worse rather than better, but turning it over to automation? Having a system that is entirely unaware of the society and political environment in which it operates? That is very bad for legitimacy. Now, you don't need legitimacy so long as the monopoly on violence holds ...@pjc50GPT Takes the Bar Exam2023

From the Hacker News threadI am afraid that this will just lead down the path to what twitter.com/ESYudkowsky/status/17186541… was mocking. We're dictating solutions to today's threats, leaving tomorrow to its own devices. But what will tomorrow bring? As Sam Altman warns in twitter.com/sama/status/171697281596096…, superhuman persuasion is likely to be next. What does that mean? We've already had the problem of social media echo chambers leading to extremism, and online influencers creating cult-like followings. jonathanhaidt.substack.com/p/mental-hea…... is a sober warning about the dangers to mental health from this. These are connected humans accidentally persuading each other. Now imagine AI being able to drive that intentionally to a particular political end. Then remember that China controls TikTok. Will Biden's order keep China from developing that capability? Will we develop tools to identify how that might be being actively used against us? I doubt both. Instead, we'll almost certainly get security theater leading to a regulatory moat. Which is almost certain to help profit margins at established AI companies. But is unlikely to address the likely future problems that haven't materialized yet.@RationalDinoExecutive Order on Safe, Secure, and Trustworthy Artificial Intelligence2023

From the Hacker News threadImportant to note though, that even if they say it has 200k context, there's a good chance it won't be able to use all of it. For example, here is an experiment on long context recall for Claude and GPT4: twitter.com/GregKamradt/status/17270181… twitter.com/GregKamradt/status/17223867… Even though claude claims 200k tokens context, perfect memory stops at about 19k tokens. I'd personally expect the Yi-34b models to perform even worse at the task, though I have not tested it.@Jackson__Yi-34B-Chat2023

The team writing their own rendering engine is unexpected and I hope to see the same engine used in other projects too.

From the Hacker News threadExactly, I also struggle to take seriously the "security" concerns of an organisation that releases this product with plugins and no proper way to restrict them and what they can do. The prompt injections are just ridiculous and show a complete lack of thought going into the design [0]. "move fast and break things" It very much feels like they are trying to build a legislative moat, blocking out competitors and even open source projects. Ridiculous. I don't fear what this technology does to us, I fear what we do to each other because of it.

From the Hacker News threadIn general it is is not true that Argon2 should be recommended over bcrypt. Even even some of the people on the experts panel for the PHC (where Argon2 won) won’t recommend Argon2 over Bcrypt: twitter.com/TerahashCorp/status/1155129… Looks like for the typical case (~200ms calculating the hash) bcrypt beats argon2. I guess that’s what I understand from those discussions, I’m not an expert by any means.

From the Hacker News threadhave now encountered two C-level execs who came from big names, were airdropped into our startup, and then proceeded to completely mangle the parts of the company they ran. always takes at least a year for people to realize (i didn't realize it myself for the first one until AFTER he was fired seemingly out of the blue, and then you start to pattern match the subsequent ones. my personal reflection is this is a horrendous waste but is part of the benefit of being an early employee at a startup, that you get to see other pple's costly mistakes while having a lower stake in the cost. I didn't know to trust my instincts then, because org chart = truth when you are new to the game). Shreyas Doshi calls this the Incompetent Leader (twitter.com/shreyas/status/133999738033…), which i will quote below for the twitter allergic (it is a better framing than I can ever come up with): --- First-time founders, CEOs, and even employees should understand the playbook of the Incompetent Leader (IL). The IL is savvy & charismatic, and excels at 4 things: 1) Feign competence 2) Create confusion 3) Buy time 4) Fail up The IL playbook & what to do about it The IL’s most favorite move is simple: Buy Time The IL’s 2nd most favorite move is: Buy More Time. After doing this a few times, the IL’s masterstroke is: Fail Up. The IL will repeat this a few times over a 20-30 year career to reach “spectacular success” Here’s how it works: Once upon a time: IL joins a new company, with much fanfare from the CEO, who really wants this to work out. Remember, the IL is incapable of making a significant, singular impact. IL doesn’t want anyone to know this. So what does IL do? IL sets the playbook in motion. Step 1 - IL: “I don’t have the right people. Cannot execute without the right team.” CEO: “I guess that’s reasonable. Do what you have to.” Result: IL has just bought 6-9 months to go hire org leaders, managers, while hiding incompetence behind charisma & confidence. [after 6-9 months] Step 2 - IL: “Have a better team now. Look how well I’ve hired! But my org doesn’t have the right structure. Not aligned with new strategy, worried execution will suffer.” CEO: “Hmmm… fine, go ahead.” Result: IL has just bought 3 months to plan re-org, 3 more to let it settle [after 6-9 months] Step 3 - IL: “Okay, that reorg helped & my people are firing on all cylinders. But I don’t have enough cross-functional alignment. We need a company re-org/Need to bring those functions into my org/Need new cross-func leaders” CEO (pot committed): “Fine, let’s do X, Y, Z here” [after 6 more months] Step 4 - IL: “Some of my key people left because of frustration with all of this. I need to replenish the gaps. Btw, look at these amazing results last quarter!” CEO to IL: “OK let me think about it” CEO (thinking): Those results are due to market tailwinds & not THAT amazing [Privately, CEO makes a call to an executive search firm to begin finding a replacement for IL] [At the next CEO/IL 1:1] CEO: “It’s time to part ways” IL (after expressing some incredulity & outrage): “I understand. I want to do what's best for the company. Let’s work on a comms plan for my departure” [IL or CEO send an announcement to the company reflecting, thanking, looking onward/upward, etc] Step 5 - (most vital move for IL) IL (in interview with hot company Foobar): “Here’s everything I built at previous company. Company grew 70% in my 2 yrs there despite all the challenges I faced” CEO of Foobar: “When can you start?” [and THAT is how our IL fails up] THE END --- he continues with a "what you should do about it", which if you are still reading here at this point go give him a "superfollow" ($10/month for his product/executive thoughts, very worth it) twitter.com/shreyas/status/133999739990…@swyxThe hardest people for founders to hire are so called C-level executives2022

From the Hacker News threadI said that there twitter.com/arjie/status/16356939270713… some hour and a half after his post which is about when I saw it. I didn't realize others also did. They felt isomorphic to me. If the AI generated content is regurgitation of previous content, novel human-generated content will stand out and human-generated content will become valuable. i.e. the balancing mechanism is that novelty will beat dumb replication in the same way that an active manager who has true alpha can beat a passive fund. Now, personally, I think that multimodal LLM-groups plus feedback plus many more sensors is not far from where we are, so I mentioned that if AIs do become creative it's not a problem - they will be us or better! I, personally, believe that's where we'll go. Anyway, I'm not too inclined to discuss in this forum (though we can chat if you're in SF) since it's easy to misunderstand and jump into argument spirals, but I just wanted to make it clear that it's not a "gotcha" or a dunk or anything like that. Nothing is being disparaged. It's just a conversation like a normal conversation where you bring up what you think and mention ideas you have that others might find interesting. If many others have brought it up, about the best I can say is that in this respect it appears I am not particularly inventive - perhaps the best evidence that LLMs are already human-like ;)@arjieWe can't all use AI.

Sama seems to be one of them [1]. So, I say to sama, be fearless and invent the future. After all, it's not something new, and in the end, everyone is destined for liberation.

From the Hacker News threadA clearer description of the bug is here: twitter.com/Tims_Pants/status/173051513… It's wild that this sort of bug got through testing. As a diabetic it feels like our insulin pump software is very conservative and lacking in features especially compared to what some of the "closed loop" things would like to do. That seems reasonable if the manufacturers are having to do lots of safety testing. But if bugs like this are getting through then the testing obviously isn't anywhere near as robust as we'd like.@omhMy insulin pump controller has a bug2023
