If I told you that hitting yourself in the dick with a hammer was good for you, would you have as much support and deference for The Schwanzhammertherapie Hypothesis as you do for hitting yourself all over with ionizing radiation? After all, I can't find any studies disproving it.

Here is how Schwanzhammertherapie works: 'cellular repair in the body is stimulated, the number of dick hammerings is reduced'.

- We build the Thread Inference Model (TIM) based on the transformer architecture, and its dedicated runtime TIMRUN.

- TIM + TIMRUN = Intelligent workflow generation, context engineering, and multi-hop tool use happens at the runtime level

- TIM + TIMRUN supports virtually unlimited reasoning enabled by context pruning, significantly improves the efficiency for long-horizon reasoning tasks

- Inference API is live at https://subconscious.dev/

- More details: https://github.com/subconscious-systems/TIMRUN

Having played Doom, Oblivion, Blue Prince, and Clair Obscur on linux, I can tell you that the tinker steps are unnecessary. I have literally just clicked play and didn't need to think about it. This didn't require a bunch of manual setup to get to that point either; I installed Endeavour and it installed the drivers I needed, then I installed Steam as normal and it was like nothing had changed from my Windows install.

People will post their tinker steps for everything. It's often just to disable the steam overlay, or inject their own overlay, or whatever they think gets them an extra 2 fps. It's linux and people love to configure it their way, but honestly steam/proton handles it automatically 99% of the time.

Hear, hear.

Although I'd slightly rephrase that to "if you don't change anything, you should end up running pretty much the same code locally as in CI".

GitHub Actions is really annoying for this, as it has no supported local mode. Act is amazing, but insufficient: the default runner images are huge, so you can't use the same environment, and it's not supported.

Pre-commit on the other hand is fantastic for this kind of issue, as you can run it locally and it'll fairly trivially run the same checks in CI as it does locally. You want it to be fast, though, and in practice I normally wind up having pre-commit run only cacheable tests locally and exclude any build and test hooks from CI because I'll run them as separate CI jobs.

I did release my own GHA action for pre-commit (https://github.com/marketplace/actions/cached-pre-commit), because the official one doesn't cache very heavily and the author prefers folk to use his competing service.

> Also... 2FA?

Yes, they reset that too, allegedly. IIUC, according to the complaint (which may or may not be accurate, of course) they got a user's password by just asking. Then they also got a vpn u&p for the same user (user1). Then they gathered some internal data and changed user2's phone number (using the same helpdesk, different conversation, I think) so they can bypass some 2fa. User2 was working in IT security...

Every security measure is as secure as the recovery mechanism. And if that mechanism relies on humans, they become the weakest link. The fact that they didn't perform any checks, and went ahead and changed 2! credentials via the same helpedsk without even sending an e-mail or you know, asking a question or two is bonkers.

> What was true last year may be false today. For instance, ...

Good example of a medical QA dataset shifting but not a good example of a medical "fact" since it is an opinion. Another way to think about shifting medical targets over time would be things like environmental or behavioral risk factors changing.

Anyways, thank you for putting this dataset together, certainly we need more third-party benchmarks with careful annotations done. I think it would be wise if you segregate tasks between factual observations of data, population-scale opinions (guidelines/recommendations), and individual-scale opinions (prognosis/diagnosis). Ideally there would be some formal taxonomy for this eventually like OMOP CDM, maybe there is already in some dusty corner of pubmed.

We made a blogpost "TF-IDF in a nutshell" - https://manticoresearch.com/blog/tf-idf-in-a-nutshell/

Manticore Search's query language is more expressive than Lucene's. While Lucene supports basic boolean logic, field search, phrase queries, wildcards, and proximity, Manticore adds many powerful operators. These include quorum matching (/N), strict word order (<<), NEAR/NOTNEAR proximity, MAYBE (soft OR), exact form (=word), position anchors (^word, word$), full regular expressions, and more. Manticore uses SQL-style syntax with a MATCH() clause for full-text search, making it easier to combine text search with filters and ranking.
Crypto Doesn't Need Blockchain
by ricecat | 2025-07-23 15:36:32+00:00
Most people think “crypto” means blockchain. Big public ledgers like Bitcoin and Ethereum where every transaction is stamped into eternity. But blockchains were never designed for privacy. They're loud by default. Transparent by design. Every payment is a broadcast. Every balance, a public file.

That might be fine in clean systems. But in cyberpunk economics — messy, low-trust, and full of watchers — broadcasting your entire financial life is not just unnecessary. It’s dangerous.

I am struggling with justification for CI/CD pipelines that are so complex this kind of additional tooling becomes necessary.

There are ways to refactor your technology so that you don't have to suffer so much at integration and deployment time. For example, the use of containers and hosted SQL where neither are required can instantly 10x+ the complexity of deploying your software.

The last few B2B/SaaS projects I worked on had CI/CD built into the actual product. Writing a simple console app that polls SCM for commits, runs dotnet build and then performs a filesystem operation is approximately all we've ever needed. The only additional enhancement was zipping the artifacts to an S3 bucket so that we could email the link out to the customer's IT team for install in their secure on-prem instances.

I would propose a canary - If your proposed CI/CD process is so complicated that you couldn't write a script by hand to replicate it in an afternoon or two, you should seriously question bringing the rest of the team into that coal mine.

>At first your comment rubbed me the wrong way, too cynical.

It's only cynical if you think making money is bad! I think it's terrific that your average B student and up is mature enough to reliably take on tens of thousands of dollars in debt, and work hard for several years without any immediate reward, in exchange for a pretty reliable pathway towards high paying specialized labor for the rest of their lives. It spits in the face of the narrative that young people are too stupid, or too naive or whatever to have agency in their own lives.

>The only reason these courses get completed is the pace/cadence, GPA requirements to get jobs and the degree.

I cite The Case Against Education, as usual. [1]

>In the ‘real world’ you just learn enough to solve the problem in front of you and as you face more and more your knowledge tree expands. No one in their right mind would go through a syllabus-like sequence - it is just boring, dull as hell.

I cite too John D. Cook's "Just-in-case versus just-in-time" blog post. [2] I don't work through actual syllabi, but I love working through textbooks from start to finish. But you are also correct that I am emphatically not in my right mind, and my career has suffered for it. ;)

That's not how you would do it with Cerebras. 44GB is SRAM, so on chip memory, not HBM memory where you would store most of the params. For reference one GB200 has only 126MB of SRAM, if you tried to estimate how many GB200 you would need for a 2TB model just by looking at the L2 cache size you would get 16k GB200 aka ~600M$, obviously way off.

Yes but Cerebras achieves its speed by using SRAM.

Discipline is just making the same choice every time no matter how you feel or what thoughts enter your mind. Your mind will lie to you with thoughts and feelings about why you can’t attend to a lecture. Treat your mind like a child pretending to be sick to get out of school.

Even if it is true that in the moment you aren’t focused or whatever other excuses your mind comes up with, so what? “Go to class” anyway. At worst you learn nothing but improve your discipline skills.

Set a regular time to watch the lectures so you can’t lie to yourself about doing it later.

I want to be clear, it isn’t about willing yourself through it despite everything even if it can read that way. It’s about honoring the choice you made to attend to the lectures and not accepting excuses from your mind.

Recognizing that you can choose, recognizing that past you had good intentions for you and deserves you to honor those intentions, and recognizing that your thoughts and feelings in the moment may not be true and “aren’t the boss of you” even if they are true helps tremendously.

I am practicing GTD since ~15 years already, but while I stick to some practices (review, inbox and so on), I have a simpler setup for projects and files, sufficient for my needs. One of the lessons is that GTD and productivity systems are not about tools - I am equally productive (or unproductive) in emacs, omnifocus, reminders. The advantage of OF and reminders is that I don't have to look after sync, workflow-wise I quickly learn to navigate around idiosyncrasies of each of them and settle on the same workflow, helping myself with scripts and glue code where I need it.

This said, I still keep my long-term notes in denote, because it works and I don't trust Apple Notes for long-term stuff (missing built-in export).

I have the same doubts, it's like the old rule of reading a newspaper story. When it's outside your area of expertise you think they're a genius. When it's something you know a lot about you think it's an idiot.

But it might still help, especially if you think about the LLM as a fellow student rather than as a teacher. You try to catch it out, spot where it's misunderstood. Explain to it what you understand and see if it corrects you?
by pyuser583 | 2025-07-23 15:38:13+00:00
I agree, but there is an important side-effect of this statement: it's possible to criticize science, without criticizing scientists. Or at least without criticizing rank and file scientists.

There are many political issues where activists claim "the science has spoken." When critics respond by saying, "the science system is broken and is spitting out garbage", we have to take those claims very seriously.

That doesn't mean the science is wrong. Even though the climate science system is far from perfect, climate change is real and human made.

On the other hand, some of the science on gender medicine is not as established medical associates would have us believe (yet, this might change in a few years). But that doesn't stop reputable science groups from making false claims.

The definition of "capitalism" has not changed. Rather, capitalism has progressed at its logical conclusion - turning more and more things into capital. This is frustrating when we want to champion the progress that capitalism has brought, but it is what it is.

It seems like you're trying to invoke some pure version of capitalism that wasn't corrupted by imaginary property and other government giveaways [0], wasn't corrupted by money printing debt treadmill demanding ever-more assets to collateralize, didn't result in ever-increasing wealth concentration, etc. But this isn't what we have, and it's not clear that we could have even possibly had something different. Thinking that a problem can be solved merely by applying more vigilance is the fallacy of fundamentalism.

By regroup at another term, I mean describing the things we like about capitalism, so we can hopefully have some of those things even as the modern distaste for capitalism as a whole grows. Hence the reference to free markets in my original comment [1]. Things like private ownership, decentralization, competition, individual liberty, a stomach for some inequality, and so on.

[0] radio spectrum is another good example. Turning most of it into exclusive privately-administered slices definitely solved real problems, especially of technology at the time. But this was blessed by academic hand-waving away the downsides (Coase) to support the lucrative agenda. And it has certainly created real entrenched problems in the current day - now most innovation is being done in the tiny slices of unlicensed spectrum.

[1] FWIW "free market" is still probably not a good term to rally around given how much it's already been staked out by people interested in control rather than freedom, only looking to apply "freedoms" that increase their own power

Especially for weird and obscure peripherals. Good chance you can plug something into a linux machine and it'll detect it and just work because someone way smarter than me also owns that device and got a driver for it mainlined into the kernel.

On the Windows side of things, you can run into situations where you have really old specialized devices where the manufacturer is long gone, so the driver downloads don't exist anymore.
by nicce | 2025-07-23 15:38:22+00:00
> Woman not feeling safe with unknown (and largely unvetted) Male drivers (or passengers) is a valid concern. It feels more like a bandaid than an actual fix, but it is an "Easy" solution to a problem. The ideal should be that we don't need this, not that we add in more filters like this. But for many reasons we as a society are not there.

Instead of building trust and ensuring that all Uber drivers are trustworthy drivers - they add option to avoid "potentially" less trustworthy drivers. Latter option is cheaper.

How exactly are they unsanity disasters? I would much rather use a urinal and never need to touch anything (besides myself, which unless I myself am unsanitary that should be clean) than need to either sit down and make contact with a surface a bunch of other people have made contact with or need to lift down and raise a lid to use that if I am standing.

Looking online I can't find anything about how they are any less sanitary than just a public bathroom is to begin with.

Maybe a hot take, but for a modern overview of the way people at large interact with computers, I find it almost disingenuous to paint it in a positive light - wonder included - without also showing the dark sides. The gray area only exists because the machines themselves are so capable when removed from the realities of how they're used.

It's as if we have the cure for cancer, but we only give it to people that are willing to watch 1 hour of ads every day. Like, yeah, the technology is great, but that social implication is terrifying.

To me, a book strictly about the wonder - ignoring these realities - feels.. vapid? dishonest? I don't want a word quite so loaded, but I'm struggling to find a better one.

This does hit home for me though. I'm currently working on a re-write of my pages on this subject on my website [0], where the current public version there really is overly complain-y and really misses the mark. The new version I'm working on explicitly alternates between negatives and positives, with sections that alternate between dark with light text and light with dark text to indicate the shift in tone and as much as I think that's beneficial for a reader, it's even more so for me as the author, to recognize when I'm writing too much in the "dark" section.

At the same time, I don't want to fall into the fallacy of moderation. If one side says climate change isn't real and one side does, it's not as if truth is somewhere in the middle. It's real. It's bad. Same for anything about computers. If I say right to repair, the DMCA, enshitification, etc. etc. are huge problems and pretend we're doing enough to fix them, that's just as dishonest.

Writing this has convinced me to pick up OP's book and read it, if for no other reason than to be inspired by the meta, the framing that I'm talking about - though I'm sure it'll be a good read in its own right. (Even if my prior, top-level comment about being unsure of the meat still holds)

If you get a big enough telescope it will gather enough light to where you'll see things in proper color. I've seen the Orion nebula with a 10 inch reflector in a good location and the rich pinks, blues and reds were impossible to miss. This is the actual photons emitted from that object hitting your retina so it's about as "true color" as you can get.

I think when astrophotographers are trying to render an image it makes sense that they would want the colors to match what your eyes would see looking through a good scope.

Mostly self-taught, been very lucky with the people I've encountered. Regularly accused of STEM/CS because I read far too many manuals. Actually not as 'classically trained' as I'd prefer... but also don't care; servile nonsense all the way down.

Have done almost every job, found system administration/DevOps/SRE stuff the most interesting. Security stuff is cool but also too product-oriented for my tastes.

The post argues that people cling to beliefs not because they ignore facts, but because belief-change requires restructuring entire systems of interconnected ideas that is emotionally and psychologically demanding.

This reminds me of a passage from yuval harari book Nexus : “…… even the most truthful accounts of reality can never represent it in full. There are always some aspects of reality that are neglected or distorted in every representation truth then isn’t a one-to-one representation of reality rather truth is something that brings our attention to certain aspects of reality while inevitably ignoring our aspects, no account of reality is hundred percent accurate, but some accounts are nevertheless more truthful than the others”

So belief system can be thought of perceived structured reality in one’s mind organized around some supporting facts. It would be valuable for researchers to examine and model what these belief system structure DAGs look like for groups with opposing views on major issues, such as climate change or democracy

> It really depends on what I'm doing

To me that's the part we're really missing on mobile. There's times a lot of controls are needed and other where they need to disappear.

We have that in classic UIs with collapsible tool bars and optional panels, things that will stay where they're set until explicitly hidden or moved away.

Having that kind of option to pin back the buttons when/as long as needed would make minimalist designs a lot more useable IMHO.

Yes off-shore manufacturers have lower labor and environmental standards. Wealthy countries indirectly benefit from exploitation.

You'd have to somehow convince or force hospitals to pay more for disposable medical supplies. They're not going to pick the USA made mask when they can get a Malaysian one. Domestic manufacturers are only going to build new plants and hire with a long term policy shift.

Americans would be pissed once everything triples in price.

Well, I have been told by many people to install Windows on their PC or laptop. I installed Linux instead. They were quite happy with that.

If you want it out of the box, there are laptops out there with Linux pre-installed, but it is not as common, unfortunately.

So I do not see the irony. They usually ask someone to install an OS, or they buy a computer pre-installed with an OS.

> This should be a discussion on how valid it is for police to profile people.

Exactly - though in this case I'm not sure what that means - if they 'feel more alert and suspicious' - that's just going on in their head ( pretty difficult to control that ). If on the other hand it means you are constantly getting stopped and searched that's another issue - but then you could argue that's then argument about the stop and search rules in whatever country.

ie what counts as reasonable grounds for the police to take concrete action.

Oh this is pretty interesting. One thing that's also interesting to note is that the Azure Blob Storage version of GitHub Actions Cache is actually a sort of V2, although internally it is just a brand new service with the internal version of V1. The old service was a REST-ish service that abstracted the storage backend, and it is still used by GitHub Enterprise. The new service is a TWIRP-based system where you directly store things into Azure using signed URLs from the TWIRP side. I reverse engineered this to implement support for the new cache API in Determinate System's Magic Nix Cache which abruptly stopped working earlier this year when GitHub disabled the old API on GitHub.com. One thing that's annoying is GitHub seems to continue to tacitly allow people to use the cache internals but stops short of providing useful things like the protobuf files used to generate the TWIRP clients. I wound up reverse engineering them from the actions/cache action's gencode, tweaking the reconstructed protobuf files until I was able to get a byte-for-byte match.

On the flip side, I did something that might break Blacksmith: I used append blobs instead of block blobs. Why? ... Because it was simpler. For block blobs you have to construct this silly XML payload with the block list or whatever. With append blobs you can just keep appending chunks of data and then seal it when you're done. I have always wondered if the fact that I am responsible for the fact that some of GitHub Actions Cache is using append blobs would ever come back to bite me, but as far as I can tell from the Azure PoV it makes very little difference, pricing seems the same at least. But either way, they need to support append blobs now probably. Sorry :)

(If you are wondering why not use the Rust Azure SDK, as far as I can tell the official Rust Azure SDK does not support using signed URLs for uploading. And frankly, it would've brought a lot of dependencies and been rather complex to integrate for other Rust reasons.)

(It would also be possible, by setting env variables a certain way, to get virtually all workflows to behave as if they're running under GitHub Enterprise, and get the old REST API. However, Azure SDK with its concurrency features probably yields better performance.)
