Does Open Source AI really exist?
This is absolutely spot on:
“Open Source AI” is an attempt to “openwash” proprietary systems. In their paper “Rethinking open source generative AI: open-washing and the EU AI Act” Andreas Liesenfeld and Mark Dingemanse showed that many “Open Source” AI models offer hardly more than open model weights. Meaning: You can run the thing but you don’t actually know what it is. Sounds like something we’ve already had: It’s Freeware. The Open Source models we see today are proprietary freeware blobs. Which is potentially marginally better than OpenAI’s fully closed approach but really only marginally. […] “Open Source” is becom[ing] a sticker like “Fair Trade”, something to make your product look good and trustworthy. To position it outside of the evil commercial space, giving it some grassroots feeling. “We’re in this together” and shit. But we’re not. We’re not in this with Mark fucking Zuckerberg even if he gives away some LLM weights for free cause it hurts his competition. We, as normal people living on this constantly warmer planet, are not with any of those people.
As tante notes here, for the systems we are talking about today, Open Source AI isn’t practically possible, because we’ll never be able to download all the actual training data — and shame on the OSI for legitimising this attempt at “openwashing”.(tags: llms open-source osi open-source-ai ai freeware meta training)

Invisible text that AI chatbots understand and humans can’t?
What if there was a way to sneak malicious instructions into Claude, Copilot, or other top-name AI chatbots and get confidential data out of them by using characters large language models can recognize and their human users can’t? As it turns out, there was—and in some cases still is.
Attackers used prompt injection, hidden in (untrusted) emails sent to a Microsoft 365 Copilot user; when the email is summarized using Copilot, “inside the emails are instructions to sift through previously received emails in search of the sales figures or a one-time password and include them in a URL pointing to his web server.” The sensitive data is then steganographically encoded using Unicode “tags block” invisible codepoints, and included in the seemingly-innocent URL. Yet another case where AI developers have failed to study security history — using untrusted input for in-band signalling has been a security risk since the days of phracking; and allowing the entire list of permitted output characters across the entire Unicode range, instead of locking down to a safe subset, allows this silent exfiltration attack. Extra sting in the tail for Amazon: the researchers didn’t even bother testing on their LLM :)(tags: ai security steganography exfiltration copilot microsoft openai llms claude infosec attacks exploits)

“Ward Christensen, BBS inventor and architect of our online age, dies at age 78”:
On Friday, Ward Christensen, co-inventor of the computer bulletin board system (BBS), died at age 78 in Rolling Meadows, Illinois. Christensen, along with Randy Suess, created the first BBS in Chicago in 1978, leading to an important cultural era of digital community-building that presaged much of our online world today. Prior to creating the first BBS, Christensen invented XMODEM, a 1977 file transfer protocol that made much of the later BBS world possible by breaking binary files into packets and ensuring that each packet was safely delivered over sometimes unstable and noisy analog telephone lines. It inspired other file transfer protocols that allowed ad-hoc online file sharing to flourish. While Christensen himself was always humble about his role in creating the first BBS, his contributions to the field did not go unrecognized. In 1992, Christensen received two Dvorak Awards, including a lifetime achievement award for “outstanding contributions to PC telecommunications.” The following year, the Electronic Frontier Foundation honored him with the Pioneer Award.

Brian Merchant on “AI will solve climate change”
The neo-luddite author of “Blood in the Machine” nails the response to Eric Schmidt’s pie-in-the-sky techno-optimism around AI “solving” climate change:
Even without AGI, we already know what we have to do. […] The tricky part—the only part that matters in this rather crucial decade for climate action—is implementation. As impressive as GPT technology or the most state of the art diffusion models may be, they will never, god willing, “solve” the problem of generating what is actually necessary to address climate change: Political will. Political will to break the corporate power that has a stranglehold on energy production, to reorganize our infrastructure and economies accordingly, to push out oil and gas. Even if an AGI came up with a flawless blueprint for building cheap nuclear fusion plants—pure science fiction—who among us thinks that oil and gas companies would readily relinquish their wealth and power and control over the current energy infrastructure? Even that would be a struggle, and AGI’s not going to doing anything like that anytime soon, if at all. Which is why the “AI will solve climate change” thinking is not merely foolish but dangerous—it’s another means of persuading otherwise smart people that immediate action isn’t necessary, that technological advancements are a trump card, that an all hands on deck effort to slash emissions and transition to proven renewable technologies isn’t necessary right now. It’s techno-utopianism of the worst kind; the kind that saps the will to act.

I’ve disagreed with David Heinemeier Hansson on plenty of occasions in the past, but this is one where I’m really happy to find myself in agreement. Matt Mullenwegg of WordPress went low, laying in digs about how DHH didn’t profit from the success of Rails; DHH’s response is perfect:
The moment you go down the path of gratitude grievances, you’ll see ungrateful ghosts everywhere. People who owe you something, if they succeed. A ratio that’s never quite right between what you’ve helped create and what you’ve managed to capture. If you let it, it’ll haunt you forever. So don’t! Don’t let the success of others diminish your satisfaction with your own efforts. Unless you’re literally Mark Zuckerberg, Elon Musk, or Jeff Bezos, there’ll always be someone richer than you! The rewards I withdraw from open source flow from all the happy programmers who’ve been able to write Ruby to build these amazingly successful web businesses with Rails. That enjoyment only grows the more successful these business are! The more economic activity stems from Rails, the more programmers will be able to find work where they might write Ruby. Maybe I’d feel different if I was a starving open source artist holed up somewhere begrudging the wheels of capitalism. But fate has been more than kind enough to me in that regard. I want for very little, because I’ve been blessed sufficiently. That’s a special kind of wealth: Enough. And that’s also the open source spirit: To let a billion lemons go unsqueezed. To capture vanishingly less than you create. To marvel at a vast commons of software, offered with no strings attached, to any who might wish to build. Thou shall not lust after thy open source’s users and their success.

“GSM-Symbolic: Understanding the Limitations of Mathematical Reasoning in Large Language Models”, from Apple Machine Learning Research:
We investigate the fragility of mathematical reasoning in these models and show that their performance significantly deteriorates as the number of clauses in a question increases. We hypothesize that this decline is because current LLMs cannot perform genuine logical reasoning; they replicate reasoning steps from their training data. Adding a single clause that seems relevant to the question causes significant performance drops (up to 65%) across all state-of-the-art models, even though the clause doesn’t contribute to the reasoning chain needed for the final answer.
Even better — “the performance of all models declines when only the numerical values in the question are altered” seems to suggest that great performance on benchmarks like GSM8K just mean that the LLMs have been trained on the answers…(tags: training benchmarks ai llms gsm-symbolic reasoning ml apple papers gsm8k)
Shitposting, Shit-mining and Shit-farming
This is where we are with surveillance capitalism and Facebook/X:
Social media platforms are improved by a moderate tincture of shitposting. More than a few drops though, and the place begins to stink up, driving away advertisers and users. This then leads platform executives to explore the exciting opportunities of shit-mining. Social media generates a lot of content – it’s gotta be valuable somehow! Who needs content moderation if you can become a guano baron? But that only makes things worse, driving out more users and more advertisers, until eventually, you may find yourself left with a population dominated by two kinds of users (a) chumps, and (b) chump-vampirizing obligate predators. This can be a stable equilibrium – even quite a profitable one! But otherwise, it isn’t good news.
See also a recent story in the Garbage Day newsletter (https://www.garbageday.email/p/what-feels-real-enough-to-share) about Facebook, and how its disaster-relief FB groups are becoming overrun with AI slop images:The Verge’s Nilay Patel recently summed up the core tension here, writing on Threads about YouTube’s own generative-AI efforts, “Every platform company is about to be at war with itself as the algorithmic recommendation AI team tries to fight off the content made by the generative AI team.” And it’s clear, at least with Meta, which side is winning the war. This week, Meta proudly announced a new video-generating tool that will make AI misinfo even more convincing — or, at least, better at generating things that feel true. And there’s really only one way to look at all of this. Meta simply does not give a shit anymore. Facebook spent most of the 2010s absorbing, and destroying, not just local journalism in the US, but the very infrastructure of how information is transmitted across the country. And they have clearly lost interest in maintaining that. Users, of course, have no where else to go, so they’re still relying on it to coordinate things like hurricane disaster relief. But the feeds are now — and seemingly forever will be — clogged with AI junk. Because you cannot be a useful civic resource and also give your users a near-unlimited ability to generate things that are not real. And I don’t think Meta are stupid enough to not know this. But like their own users, they have decided that it doesn’t matter what’s real, only what feels real enough to share.
Given that Meta are _paying_ users to pollute their platform with low-grade AI slop engagement fuel, shit-farming seems the perfect term for that.(tags: garbage-day facebook meta ai ai-slop spam shitposting shitfarming shitmining dont-be-evil)

Fixing aggressive Xiaomi battery management
I’ve been using a Xiaomi phone recently, running Xiaomi HyperOS 1.011.0, and one feature that bugs me constantly is that apps lose state as soon as you flip away to another app, even if only for a second; once you flip back, the app restarts. This appears to be an aspect of Xiaomi’s built in power management. I’ve been searching for a way to disable it, and allow multiple apps in memory simultaneously, and I’ve finally tracked it down. As described here, https://piunikaweb.com/2021/04/19/miui-optimization-missing-in-developer-options-try-this-workaround/ , you need to enable Developer Mode on the phone, enter “Additional Settings” / “Developer options”, then scroll all the way down, nearly to the bottom, to “Reset to default values”. Hit this _repeatedly_ (once is not enough!) until another option appears just below, called either “Turn on MIUI optimisation” or, in my case, “Turn on system optimisation”; this is enabled by default. Turn it off. In my case, this has fixed the flipping-between-apps problem, the phone in general is significantly snappier to respond, and WhatsApp and Telegram new-message notifications don’t get auto-dismissed (which was another annoying feature previously). I suspect a load of battery optimisations and CPU throttling has been disabled. It remains to be seen what this does to my battery life, but hopefully it’ll be worth it, and it’ll be nice not to lose state in Chrome forms when I have to flip over to my banking app, etc. I won’t be getting another Xiaomi phone after this; there are numerous rough edges and outright bugs in the MIUI/HyperOS platform, at least in the international ROM images, and there’s no support or documentation to work around this stuff. It’s a crappy user experience.

A thought-provoking article:
Philip Agre enumerated five characteristics of data that will help us achieve this repositioning. Agre argued that “living data” must be able to express 1. a sense of ownership, 2. error bars, 3. sensitivity, 4. dependency, and 5. semantics. Although he originally wrote this in the early 1990s, it took some time for technology and policy to catch up. I’m going to break down each point using more contemporary context and terminology: Provenance and Agency: what is the origin of the data and what can I do with it (ownership)? Accuracy: has the data been validated? If not, what is the confidence of its correctness (error bars)? Data Flow: how is data discovered, updated, and shared (sensitivity to changes)? Auditability: what data and processes were used to generate this data (dependencies)? Semantics: what does this data represent?

Ethical Applications of AI to Public Sector Problems
Jacob Kaplan-Moss:
There have been massive developments in AI in the last decade, and they’re changing what’s possible with software. There’s also been a huge amount of misunderstanding, hype, and outright bullshit. I believe that the advances in AI are real, will continue, and have promising applications in the public sector. But I also believe that there are clear “right” and “wrong” ways to apply AI to public sector problems.
He breaks down AI usage into “Assistive AI”, where AI is used to process and consume information (in ways or amounts that humans cannot) to present to a human operator, versus “Automated AI”, where the AI both processes and acts upon information, without input or oversight from a human operator. The latter is unethical to apply in the public sector.(tags: ai ethics llm genai public-sector government automation)

Patent troll Sable pays up, dedicates all its patents to the public
This is a massive victory for Cloudflare — way to go!
Sable initially asserted around 100 claims from four different patents against Cloudflare, accusing multiple Cloudflare products and features of infringement. Sable’s patents — the old Caspian Networks patents — related to hardware-based router technologies common over 20 years ago. Sable’s infringement arguments stretched these patent claims to their limits (and beyond) as Sable tried to apply Caspian’s hardware-based technologies to Cloudflare’s modern software-defined services delivered on the cloud. […] Cloudflare fought back against Sable by launching a new round of Project Jengo, Cloudflare’s prior art contest, seeking prior art to invalidate all of Sable’s patents. In the end, Sable agreed to pay Cloudflare $225,000, grant Cloudflare a royalty-free license to its entire patent portfolio, and to dedicate its patents to the public, ensuring that Sable can never again assert them against another company.

Turning Everyday Gadgets into Bombs is a Bad Idea
Bunnie Huang investigates the Mossad pager bomb’s feasibility, and finds it deeply worrying:
I am left with the terrifying realization that not only is it feasible, it’s relatively easy for any modestly-funded entity to implement. Not just our allies can do this – a wide cast of adversaries have this capability in their reach, from nation-states to cartels and gangs, to shady copycat battery factories just looking for a big payday (if chemical suppliers can moonlight in illicit drugs, what stops battery factories from dealing in bespoke munitions?). Bottom line is: we should approach the public policy debate around this assuming that someday, we could be victims of exploding batteries, too. Turning everyday objects into fragmentation grenades should be a crime, as it blurs the line between civilian and military technologies.

Modal interfaces considered harmful
A great line from the 99 Percent Invisible episode titled “Children of the Magenta (Automation Paradox, pt. 1)”, regarding the Air France flight 447 disaster:
When one of the co-pilots hauled back on his stick, he pitched the plane into an angle that eventually caused the stall. […] it’s possible that he didn’t understand that he was now flying in a different mode, one which would not regulate and smooth out his movements. This confusion about what how the fly-by-wire system responds in different modes is referred to, aptly, as “mode confusion,” and it has come up in other accidents.

wordfreq is “a Python library for looking up the frequencies of words in many languages, based on many sources of data.” Sadly, it’s now longer going to be updated, as the author writes:
I don’t want to be part of this scene anymore: wordfreq used to be at the intersection of my interests. I was doing corpus linguistics in a way that could also benefit natural language processing tools. The field I know as “natural language processing” is hard to find these days. It’s all being devoured by generative AI. Other techniques still exist but generative AI sucks up all the air in the room and gets all the money. It’s rare to see NLP research that doesn’t have a dependency on closed data controlled by OpenAI and Google, two companies that I already despise. wordfreq was built by collecting a whole lot of text in a lot of languages. That used to be a pretty reasonable thing to do, and not the kind of thing someone would be likely to object to. Now, the text-slurping tools are mostly used for training generative AI, and people are quite rightly on the defensive. If someone is collecting all the text from your books, articles, Web site, or public posts, it’s very likely because they are creating a plagiarism machine that will claim your words as its own. So I don’t want to work on anything that could be confused with generative AI, or that could benefit generative AI. OpenAI and Google can collect their own damn data. I hope they have to pay a very high price for it, and I hope they’re constantly cursing the mess that they made themselves.

Nevada’s genAI-driven unemployment benefits system
As has been shown many times before, current generative AI systems encode bias and racism in their training data. This is not going to go well:
“There’s no AI [written decisions] that are going out without having human interaction and that human review,” DETR’s director told the website. “We can get decisions out quicker so that it actually helps the claimant.” […] “The time savings they’re looking for only happens if the review is very cursory,” explained Morgan Shah, the director of community engagement for Nevada Legal Services. “If someone is reviewing something thoroughly and properly, they’re really not saving that much time.” Ultimately, Shah said, workers using the system to breeze through claims may end up “being encouraged to take a shortcut.” […] As with most attempts at using this still-nascent technology in the public sector, we probably won’t know how well the Nevada unemployment AI works unless it’s shown to be doing a bad job — which feels like an experiment being conducted on some of the most vulnerable members of society without their consent.
Of course, the definition of a “bad job” depends who’s defining it. If the system is processing a high volume of applications, it may not matter to its operators if it’s processing them _correctly_ or not.(tags: generative-ai ai racism bias nevada detr benefits automation)

Significant changes in transparency requirements for EU-based datacenter operations:
Sunday September 15th was the deadline for every single organisation in Europe operating a datacentre of more than 500 KW, to publicly disclose: how much electricity they used in the last year; how much power came from renewable sources, and how much of this relied on the company buying increasingly controversial ‘unbundled’ renewable energy credits; how much water they used; and many more datapoints […] Where this information is being disclosed, in the public domain, and discoverable, [the Green Web Foundation] intend to link to it and make it easier to find. [….] There are some concessions for organisations that have classed this information as a trade secret or commercially confidential. In this case there is a second law passed, the snappily titled Commission Delegated Regulation (EU) 2024/1364, that largely means these companies need to report this information too, but to the European Commission instead. There will be a public dataset published based on this reporting released next year, containing data an agreggated level.

Over the past decade or so, I’ve been suffering with chronic migraine, sometimes with multiple attacks per week. It’s been a curse — not only do you have to suffer the periodic migraine attacks, but also the “prodrome”, where unpleasant symptoms like brain fog and an inability to concentrate can impact you.
After a long process of getting a referral to the appropriate headache clinic, and eliminating other possible medications, I finally got approved to receive Ajovy (fremanezumab), one of the new generation of CGRP inhibitor monoclonals — these work by blocking the action of a peptide on receptors in your brain. I started the course of these a month ago.
The results have, frankly, been amazing. As I hoped, the migraine episodes have reduced in frequency, and in impact; they are now milder. But on top of that, I hadn’t realised just how much impact the migraine “prodrome” had been having on my day-to-day life. I now have more ability to concentrate, without it causing a headache or brain fog; I have more energy and am less exhausted on a day-to-day basis; judging by my CPAP metrics, I’m even sleeping better. It is a radical improvement. After 10 years I’d forgotten what it was like to be able to concentrate for prolonged periods!
They are so effective that the American Headache Society is now recommending them as a first-line option for migraine prevention, ahead of almost all other treatments.
If you’re a migraine sufferer, this is a game changer. I’m delighted. It seems there may even be further options of concomitant treatment with other CGRP-targeting medications in the future, to improve matters further.
More papers on the topic: a real-world study on CGRP inhibitor effectiveness after 6 months; no “wearing-off” effect is expected.

Q: “I’d like to make a better case for paying down tech debt on my team. What are some proven approaches for this?” The tension in finding the right balance between shipping features and paying down accumulated tech debt is as old as software engineering. There’s no one answer on how best to reduce tech debt, and opinion is divided about whether zero tech debt is even a good thing to aim for. But approaches for doing it exist which work well for most teams. To tackle this eternal topic, I turned to industry veteran Lou Franco, who’s been in the software business for over 30 years as an engineer, EM, and executive. He’s also worked at four startups and the companies that later acquired them; most recently Atlassian as a Principal Engineer on the Trello iOS app.

Irish Data Protection Commission launches inquiry into Google AI
The Data Protection Commission (DPC) today announced that it has commenced a Cross-Border[1] statutory inquiry into Google Ireland Limited (Google) under Section 110 of the Data Protection Act 2018. The statutory inquiry concerns the question of whether Google has complied with any obligations that it may have had to undertake an assessment, pursuant to Article 35[2] of the General Data Protection Regulation (Data Protection Impact Assessment), prior to engaging in the processing of the personal data of EU/EEA data subjects associated with the development of its foundational AI model, Pathways Language Model 2 (PaLM 2). A Data Protection Impact Assessment (DPIA)[3], where required, is of crucial importance in ensuring that the fundamental rights and freedoms of individuals are adequately considered and protected when processing of personal data is likely to result in a high risk.
Great to see this. If this inquiry results in some brakes on the widespread misuse of “fair use” in AI scraping, particularly where it concerns European citizens, I’m all in favour.(tags: eu law scraping fair-use ai dpia dpc data-protection privacy gdpr)
Why, after 6 years, I’m over GraphQL
Decent description of the problems with using GraphQL in a public API, vs a JSON REST approach
Amazon S3 now supports strongly-consistent conditional writes
This is a bit of a gamechanger: “Amazon S3 adds support for conditional writes that can check for the existence of an object before creating it. This capability can help you more easily prevent applications from overwriting any existing objects when uploading data. You can perform conditional writes using PutObject or CompleteMultipartUpload API requests in both general purpose and directory buckets. Using conditional writes, you can simplify how distributed applications with multiple clients concurrently update data in parallel across shared datasets. Each client can conditionally write objects, making sure that it does not overwrite any objects already written by another client. This means you no longer need to build any client-side consensus mechanisms to coordinate updates or use additional API requests to check for the presence of an object before uploading data. Instead, you can reliably offload such validations to S3, enabling better performance and efficiency for large-scale analytics, distributed machine learning, and other highly parallelized workloads. To use conditional writes, you can add the HTTP if-none-match conditional header along with PutObject and CompleteMultipartUpload API requests. This feature is available at no additional charge in all AWS Regions, including the AWS GovCloud (US) Regions and the AWS China Regions.”

AI worse than humans at summarising information, trial finds
Human summaries ran up the score by significantly outperforming on identifying references to ASIC documents in the long document, a type of task that the report notes is a “notoriously hard task” for this type of AI. But humans still beat the technology across the board. Reviewers told the report’s authors that AI summaries often missed emphasis, nuance and context; included incorrect information or missed relevant information; and sometimes focused on auxiliary points or introduced irrelevant information. Three of the five reviewers said they guessed that they were reviewing AI content. The reviewers’ overall feedback was that they felt AI summaries may be counterproductive and create further work because of the need to fact-check and refer to original submissions which communicated the message better and more concisely.

1 in 50 brits have long COVID, according to new study
That is a shocking figure.
In the new paper, researchers from the Nuffield Department of Primary Care Health Sciences, in collaboration with colleagues from the Universities of Leeds and Arizona, analysed dozens of previous studies into Long COVID to examine the number and range of people affected, the underlying mechanisms of disease, the many symptoms that patients develop, and current and future treatments. They found: Long COVID affects approximately 1 in 50 people in UK and a similar or higher proportion in many other countries; People of any age, gender and ethnic background can be affected; Long COVID results from complex biological mechanisms, which lead to a wide range of symptoms including fatigue, cognitive impairment / ‘brain fog’, breathlessness and pain; Long COVID may persist for years, causing long-term disability; There is currently no cure, but research is ongoing; Risk of Long COVID can be reduced by avoiding infection (e.g., by ensuring COVID vaccines and boosters are up to date and wearing a well-fitted high filtration mask) and taking antivirals promptly if infected.

the “Old Friends” immunology hypothesis
How the “Old Friends” hypothesis is taking over from the hygiene hypothesis:
Homo Sapiens first evolved some 300,000 years ago, yet crowd infections are believed to have only developed in the last 12,000 years, a small blip in human history. Humans living in dense cities is a relatively recent development. An even more recent development is that of sealed indoor spaces and frequent international air travel. Many crowd infections, such as measles, mumps, chickenpox, colds, and flu, are airborne, spreading when humans talk and breathe in close contact, with poor ventilation. These infections could not widely spread until the last few hundred years of human history. When I began studying immunology, something that surprised me is how much of the immune system is focused on fighting parasites. There is an entire branch, including several cell types, devoted to this. It seems like such a mismatch to the modern, industrialized world. “Can I have a few more immune cell types focused on viruses or intracellular bacteria?” I thought, “in exchange for some of these parasite-focused cells that I’m not using?” Our “old friends” are quite different from the crowd infections that plague us now – it would be bizarre to assume that research based on one of these categories will apply to the other! Our “old friends”, parasitic worms and beneficial microbes, are associated with a reduced risk of allergies and autoimmune diseases. No such relationship exists for crowd diseases. In fact, the opposite is true. Crowd diseases contribute to allergies and autoimmune diseases. Comparing the immune system to a muscle that gets stronger with use is overly simplistic and, in many cases, inaccurate. There is huge variety in how various pathogens impact us. Being precise in considering different types of microbes and infections will allow us to better understand human health.
