I’m mostly talking from personal experience. I imagine an actual well powered study on this sort of thing would be hard to do, for similar reasons a lot of fitness / nutrition studies are not great. I agree that a good diverse full body routine would help mitigate injury risk vs a less diverse routine. Obviously diminishing returns but expanding outside of the weight room is IMO also helpful for injury prevention if not quality of life. Pertinent video: https://youtu.be/rb2DPHi39FU

In general, under law, dogs are considered property. That's just a fact. It doesn't mean you can be cruel to 'em, but, under most law, they're still property.

The original piece was about Claude having a soul, about a belief that some people consider AI to be "conscious and aware", and how certain people are beginning to treat it more like a person than a machine. Unplugging a computer is unremarkable, but pulling the plug on a "person" most certainly has ethical implications.

The computer was supposed to be a cognitive partner. Engelbart called it augmentation. Kay called it a bicycle for the mind.
We got productivity apps, app stores, and now chat interfaces.
This essay examines the parallel evolution of UI and AI over 40 years - and why the convergence of semantic infrastructure and learning-based systems finally makes cognitive partnership achievable.

I still have to go through my watch list, the age old issue of not having my slides done before congress...

The 10 year of Dieselgate is interesting just from a "how bad is it really?" PoV, I saw the part about curves and other defeat devices already [1].

The Rowhammer talk is likely going to be great as well, I like Daniel's work [2].

The practical Cross-VM Spectre was interesting to show this is still a problem [3].

The opensource secure element was good for trying such a thing, but I wasn't that impressed with the content [4].

iOS: Apps persist data after full deletion
by WorldDev | 2026-01-02 20:11:41+00:00
I noticed that apps retain info after being deleted. That means we are tracked by the app even after we deleted it.

For example, if I delete whatsapp or instagram, choosing to delete all data, then restart the phone and reinstall the app, it will automatically know my account.

So there is clearly a persistence mechanism that it uses.

I tried to understand which one.

- UIDevice.identifierForVendor
Apple clearly states this identifier is changed as soon as all apps from the same vendor are deleted. that's what I tested, so this identifier is not the culprit

- DCDevice.generateToken
This only stores 2 bits on the device, so not enough to store a username

- Keychain services (password)
I checked in the password app, no password was saved for these app

- iCloud Keychain
I turned off this feature

Does anyone know the technical way apps persist data even after total deletion? One of the big appeals of Apple to me is privacy, so I'd like to understand this...

>While that might be healthier by the book, one thing it certainly decreases is time with friends and potentially time to network with others or make connections you might not otherwise.

I'm a bit confused by the conflation here. You can drink alone or socialize sober. It may be the case that kids these days are socializing in person with friends less, but it's almost certainly not because they're drinking less.

All the westerner can conclude from any of this is that we aren't doing free market capitalism hard enough yet, unfortunately.

My point is that there is nothing a priori about it, its just a question of what your goal is, what you are adapted to do and how the resistance curve of the movement is set up.

If you have a cardiovascular system that can grind through 20RM squat sets and you like it, go off. It'll be hard for most people due to the large amount of muscle mass recruited, but on the other hand, if you can load a lateral raise 5RM with acceptable range of motion, why the hell not. It just doesn't work well with dumbbells in particular.

Hi HN, maker here.

I built Blohem because I was tired of the 'metric-anxiety' on modern social platforms. I wanted a place that feels like a 'digital noise archive'—no likes, no profiles, just raw thoughts stored anonymously.

Tech Stack: It's built with Next.js, but instead of Vercel, I dockerized it and deployed it on Azure to have full control over the backend nodes (which I call 'Witnesses').

It's an experiment in digital minimalism. I'd love to hear your thoughts on the UI/UX and the concept.

Cheers, mekod

Location: Rochester, NY

Remote: Yes

Willing to relocate: No

Technologies: Actively using Python, Scala, and JS. Experience with Rust, PHP, Java, Ruby, and others.

Résumé/CV: https://www.linkedin.com/in/michaelmior/

Email: michael@mior.ca

I'm a computer science professor with a PhD looking to make a move back to industry. I've been enjoying the teaching and research I'm doing, but I'm interested in getting back to making products people actually use. I have significant database and systems experience including as one of the PMC members of Apache Calcite, an open source relational data management platform used by Uber, Netflix, and others.

I have 10+ years experience as a software engineer/researcher (including as a grad student) and my lab, the Data Unity Lab at the Rochester Institute of Technology works on some cool stuff related to non-relational data management. I still find the time to write code both with my students and my own. Delivering high-quality code along with any work I publish is very important to me.

I'm interested in either senior software/data engineering or data science roles. The technology used is less important to me than an interesting product and a great team. I have a lot of experience picking up new tech quickly and I'm looking forward to using that in new ways.

I wouldn't say "failure". There are many, many IPv6 client devices out there, mostly on mobile networks. And it works great and they do well and the tools all support it very well.

But IPv4 will never, ever die. The rise of NAT as a pervasive security paradigm[1] basically neuters the one true advantage IPv6 brought to the table by hiding every client environment behind a single address, and the rise of "cloud everything" means that no one cares enough about reaching peer devices anyway. Just this morning my son asked me to share a playlist, so of course I just send him a link to a YouTube Music URL. Want to work on a spreadsheet for family finances with your spouse in the next room? It lives in a datacenter in The Dalles.

[1] And yes, we absolutely rely as a collective society on all our local devices being hidden. Yes, I understand how it works, and how firewalls could do this with globally writable addresses too, yada yada. But in practice NAT is best. It just is.

My argument is that bullets move slow, can miss causing obvious damage to surrounding infra that shows up on cameras, that they are loud and that minaturization is important to making this a real trend. You started with CWIS which is massive and has a lot of maintenance. I don't have information on the small precise turrets you mentioned. Please provide it. Either way my arguments still stand. What may have not been done in the past because it was technically possible but not practical is now quickly becoming technically possible and practical and therefore will be built. We are seeing minaturization, simplification and movement towards a weapon system that minimizes camera unfriendly damage while also seeing a massive improvement in surveillance identification and tracking tech. The trend is there and it is pretty clear that it leads to a capability to track a city down to the individual and to be able, at any time, to hit a button to kill a bunch of people. This is a capability that will be developed and what is morally right never stops weapons development, just what is practical. We need to have the discussion sooner rather than later about how to handle these weapons on the battlefield and just as importantly how to keep them away as 'peacekeeping' use in civilian populations.

Hi guys,

I’ve been working on a small side project called FoodieLens and wanted to share it here for feedback.

The idea came from constantly traveling and staring at menus where:

There were no images

The language wasn’t familiar

Never heard of the dishes

Manually searching on google takes too long

FoodieLens lets you:

snap a photo of a restaurant menu

get translations

see real images of what the dishes actually look like

It’s a simple web app (no install) and I would love to have people try it out.

> but several browser tabs and Electron/WebView apps running just fine on an early 2010s PC I employ.

"My car runs fine with the five anvils in the trunk" isn't the argument you're looking for.

Performance isn't the only problem with Electron either. Electron apps fail to integrate with native system components both from look and feel and accessibility aspects like incorrect zoom levels on HiDPI displays etc. They are even worse than browser tabs in that manner.

> I don't see an XAML based C# .NET desktop app performing marginally better than an equivalent well-written Electron app either

RAM usage would be at least an order of magnitude different. Nothing to do with how well-written it is either. It's inevitable.

That's sort of my thought too. Grok can't apologize, but it also can't do anything without being told. A hammer can't apologize, but it also doesn't know the difference between hitting a nail or a person. Perhaps we could design a hammer that does less harm to a human but if it comes at the cost of being a worse hammer I don't want it

Only due to the mobile device space. It will not take off outside of Wireless telco networks.

Take a look at the IPv6 Google graph that everyone loves so much:

https://www.google.com/intl/en/ipv6/statistics.html

You can clearly see an initial steep spike to the curve where mobile adoption was new and fierce, and then the curve starts slowly becoming less steep over the last 10 years. It will peter out and remain steady when mobile device adoption reaches critical mass.

>0.42 USD per student (15 USD total)

Reminder: This professor's school costs $90k a year, with over $200k total cost to get an MBA. If that tuition isn't going down because the professor cut corners to do an oral exam of ~35 students for literally less than a dollar each, then this is nothing more than a professor valuing getting to slack off higher than they value your education.

>And here is the delicious part: you can give the whole setup to the students and let them prepare for the exam by practicing it multiple times. Unlike traditional exams, where leaked questions are a disaster, here the questions are generated fresh each time. The more you practice, the better you get. That is... actually how learning is supposed to work.

No, students are supposed to learn the material and have an exam that fairly evaluates this. Anyone who has spent time on those old terrible online physics coursework sites like Mastering Physics understands that grinding away practicing exams doesn't improve your understanding of the material; it just improves your ability to pass the arbitrary evaluation criteria. It's the same with practicing leetcode before interviews. Doing yet another dynamic programming practice problem doesn't really make you a better SWE.

Minmaxing grades and other external rewards is how we got to the place we're at now. Please stop enshittifying education further.

The subject is "AI exams", not "exams". GGP expressed that they believe that AI exams would be an extremely unpleasant experience to have your future determined by, something I find myself in agreement with. GP implied that students deserve this even though it's unpleasant because of their actions, in other words they agree that this is unpleasant but are okay with it because this is punishment for AI cheating. (And which is being applied to all students regardless of whether they cheated, hence the "collective" aspect of the punishment.)

POSSE can be applied to more than just social networks, it can be used to disrupt every marketplace!

In fact, I’m building open source SaaS for every vertical and leveraging that to build an interoperable, decentralized marketplace.

Social media is a marketplace as well. The good being sold is people’s content and the cost you pay is with your attention. The marketplace’s cut is ads and selling your data.

https://www.google.com/intl/en/ipv6/statistics.html it's still going up (we are in some sort of cyclic downturn right now that I don't understand).

Next year that chart will finally cross 50%. It was a mere 30% in 2030. Developing country mobile phone networks will continue to push it higher.

All we need to do is start having rich governments mandate IPv6, and also mandate IPv4 downtime as a punishment for those that don't comply / chaos engineering for the system as a whole. Then we can quickly finish the job.

Miri is so good. Thank you Ralf for dedicating yourself to this project for so long.

When I have Rust projects with subsystems that must be unsafe, I will design them around Miri testability. This mostly means writing small unit-testable units and isolating I/O as much as possible. I almost always find I have made mistakes that Miri catches.

Because of their existing product lines, I look at this more like marketing or market research. I'm pretty confident that this will actually be made. For one, the company actually has experience making and selling devices. This is a bit more ambitious than an accessory keyboard, but it's at least experience making something. Second, the pre-order reservation is about half of the full pre-order price. Unlike most Kickstarters where you have to front 100% of the money.

At some point, Kickstarter (et al) campaigns switch from high-risk speculative products to marketing pitches (get in early!). I think this is one of the later. You're right that they could probably have (or have already) funded the product development themselves. I think this pitch is trying to build a market early in the year before potential competitor products are announced.

I don't recall my issues being media file or workload specific [0]. It was specifically just general frontend stuff I believe [1]. Although I should probably also mention that I don't remember much to begin with, other than my decidedly negative conclusion that made me switch players, and the overall personal narrative around that. It's been quite a few years if not a whole decade.

[0] Doesn't mean there weren't any, but then I was not doing anything special. Just watched anime, listened to music, streamed YouTube. Hardly an extraordinary workload for VLC, or indeed any media player in general.

[1] I remember them changing around the volume slider widget back and forth ad nauseam for example, and that becoming in some particular way defective that I cannot recall.

> It's pretty obvious to anyone with two neurons to spark together that the problem here isn't "amount of power you can suck out of the display port".

Nobody said it was.

I gave that out as and example of a feature that DP might adopt in order to sway TV manufacturers and media device manufactures to adopt it.

But not for nothing, 0.25W and 1.67W are virtually the same thing in terms of application. Just because it's "6.6x more" doesn't mean that it's usable. 0.25W is 25x more than 0.01W, that doesn't make it practically usable for anything related to media.

It's understandable that IPv6 would be ambitious rather than incremental given the cost of rolling out a new protocol; the bells-and-whistles IPv6 design is probably just a relatively small constant factor more expensive than the simplest possible address space expansion. Viewed that way, you only get the one chance to update the protocol, you might as well fix whatever you can.
by alt227 | 2026-01-02 20:20:12+00:00
Yep, and even with all those countries with their billions of mobile devices IPv6 use still hasnt even reached 50%.

Pretty much all ISPs hand out both IPv6 and IPv4 addresses to their clients, this is nothing new. When they start only issueing IPv6 IPs is when it would start truly taking off, but it will never get to that point and it will never happen.

> keep GUI apps and casual tools imperative, and treat Nix as the source of truth for the stuff that actually blocks you from doing work

I landed somewhere similar for gaming.

When I first got my Legion Go, there were a whole bunch of gaming distros, but none was more popular than the other. I read a bit about immutability, got curious, and installed Jovian-NixOS (which is to NixOS what Bazzite is to Fedora).

I liked that it gave me the Steam Deck experience on unofficial hardware, and it was neat to be able to play with e.g. replacing the desktop shell. However, a keyboard-centric configuration scheme is a bad pairing for a touch-centric device. Little things, like changing the timezone, became needlessly frictionful.

Now I'm on the official SteamOS, with Nix as the package manager. It seems to be a good pairing. Nix lets me install Linux utilities on Steam's otherwise-immutable filesystem. And I can use the Steam UI to change things like the time.

I'll probably write an article in the next few weeks on using Nix to make Linux-native copies of Windows-built games.
