phh··on ChromeOS will soon be developed on large portions of the Android stack
Gotta admit I'm curious there. I've rocked a rk3399 chromebook for years (stopped roughly when it got deprecated) without issues, and I was stressing it with crouton. My gf is still using a rk3288 chromebook "fine" (it's no longer her daily driver though). Those are low-end 8yo devices.

Anecdotal counter-point I have a colleague with a Samsung Galaxy Tab A 8" 2019 (SM-T290), and after just 3 years it became absolutely unusable, even after a factory reset. And it's "by design": it shipped with 2GB RAM, which was usable in Google/Android 9 (shipped OS), but just completely dead on Google/Android 11 (updated OS). Obviously I saved that device from oblivion with a Google-less Android that takes half as much RAM.

phh··on ChromeOS will soon be developed on large portions of the Android stack
Both real-world and on-paper status are literally the exact opposite of what you're describing.

As others have already mentioned, just stating the facts about long-term support: chromebooks have much longer support than Android devices. Both looking at the 99-percentile, the median, and the 1-percentile.

Chromebooks don't get stupid bugs that require workarounds in userspace like: - BPF maps being broken because someone at Mediatek ran some proprietary static analyser and blindly pushed some fix - Camera only works properly in the OEM app - GL drivers are upgraded once every blood moon and very OEM has its custom GL version - Treble doesn't break because Samsung decided that mount loops were dangerously insecure at a time it wasn't required - You don't need to keep workarounds for mainline kernels that you can't upgrade, because Google/Android forbids you to upgrade your kernel [1]

Android deprecates driver after 3 years [2], so vendor need to do a lot of work on a very frequent basis. As an OEM, I just want to do my (painful) contributions to mainline, and have them maintain it. Android actively hinders me from doing that.

As an Android OS developer, I could go on and on and on about the stupid issues that Android kernels get that Chromebooks don't. All of those issues would happen just exactly the same on Fuchsia.

I'm not saying ChromeOS' development method works for smartphones, it doesn't. I'm not saying it is desirable, I think it isn't (because it completely kills most innovation). But ChromeOS handles fragmentation better than Android on every single criteria you could imagine.

[1] Google/Android added a bunch a new stupid policies that actually prevent me from upgrading kernels on deployed devices

[2] Yes there is actual planned obsolescence nowadays in Android. It wasn't the case few years ago where obsolescence was accidental

That's literally just FBI's customer account at Cox.

phh··on Hacking millions of modems and investigating who hacked my modem
Counterpoint: ISP with over 1M customers have the incentives of upgrading their HGW "forever" to reduce Capex. My employer (Free, French ISP also shipping HGW to Italia as Iliad) still upgrade their HGW released in 2011 (though if you have yours dating back from 2011, have it replaced (your oled screen is probably dead ;) to get more recent wifi cards). It runs a modern Linux 6.4. You get modern nifties like airtime QoS, got upgraded mobile apps if you wish, and uh lots of software features.
phh··on Self-hosted offline transcription and diarization service with LLM summary
Well it'll always depend on the length of the meeting to summarize. But they are using mistral which clocks at 32k context. With an average of 150 spoken words per minute, 1 token ~= word (which is rather pessimistic), that's 3h30m of meeting. So I guess that's okay?

phh··on Multi AI agent systems using OpenAI's assistants API
I've indeed refused to work with some providers giving only a chat interface and not a completion interface because it made the communication "less natural" to the model (like adding new system messages in between for function calling on models which don't officially does it, or adding other categories than system/user/assistant)
phh··on Deblur-GS: 3D Gaussian splatting from camera motion blurred images
Hi,

I'm trying to make an opensource NN camera pipeline (objective is to be able to run on smartphones but offline, not real-time), and I'm still barely managing the demosaicing part... would you be open to discussing with me?

phh··on Alternative clouds are booming as companies seek cheaper access to GPUs
You feel like it's new, I don't. I've evaluated migrating from full blown servers to cloud at various scales for various usages: OTA server for 1M active devices, stat server for 1M active devices, build server for Android (both pure Android that parallelizes and checks out super nearly and vendor Android where they broke all of that). In all those cases the cost of cloud was like an order of magnitude costlier. You're mentioning SSD, the various clouds I tried (I couldn't remember which I tried sorry...) had bad storage performance (it was especially bad when building Android). Also not all those servers were maintained by my employer, when we pay top end 100Gbps server we can pay someone to maintain it for us as well for much lower money than the "cloud tax".

I have no doubt there are great use case for cloud, and that at the proper scale you can negotiate, and I understand that startups might be faster moving with the cloud. But I feel like the highest value cloud provides is 1. replacing capex with opex, and 2. making scaling easier with the direction: cloud is pay first, get questions from direction later. "on-prem" is negotiate with the direction until the service degrades and then scramble to integrate the new server under the pressure.

phh··on One bad apple can spoil your IPv6 privacy (2022)
So uh, this seems to imply that ISP rotating ipv6 prefix is "obvious", but uh. Really? I don't think I've ever seen this implemented willingly (many have dynamic allocation, but it's changing so slowly that it looks more like a bug than a feature). Does some people have other experience?

I was wondering what kind of IoT could be widespread enough to pose a significant problem or if it was rather statistical, but they mention TVs. And uh yeah, TVs during their lifetime discuss with a huge range of providers, so this indeed broadcasts to

The privacy handling of the article writing isn't great imo. Only an ISP should have access to those data, not external researchers. I even fail to see how it can be GPDR compliant. That being said, operators won't spontaneously write those articles, so well, this one is usefl.

Overall this is an interesting article. I think ISPs doing prefix rotations can easily detect devices and warn the user and/or isolate the bad device (through symmetric NAT for instance -- I think this is an okay compromise, it's not a horrible hack), which this article shines light on. Cool.

phh··on Rabbit R1 source code [part 1]
> In reality, they're simply relying on several Playwright automation scripts to do the job for you, which is why they only support four apps: Spotify, Midjourney, Doordash, and UberEats.

I think that part is mostly fine? I'd rather make give a LLM access to https://woob.tech to be my personal assistant while parsing 99% less noise, than have a LLM that parse and understand stupidly complicated web pages, and randomly fail at the task because the name of my doctor is bobby drop tables.

That being said, it can be interesting to use LLMs to assist creating woob plugins.

> * There's no mention of model performance on recall tasks. Models with attention do well on recall tasks, but models without it, like this one, tend to do poorly.[a] What is the performance of this model on recall tasks?

For what it's worth, RWKV's (another "transformer-less") website on that matter mention that yes it's bad on recall, but for the vast majority of tasks you can just ask the question *before* the content, and it'll handle the task just fine. (I'm just reporting, I haven't spent time trying myself)

phh··on Amazon ditches 'just walk out' checkouts at its grocery stores
We've had that in France for years, and noone uses that as far as I can tell.

The main usage I see is mainly self checkout.

Please note that I'm biased towards dense areas. We have on-the-go scanning in super stores as well, I feel it's not being used but I could be wrong

phh··on VLC can't update on Android without giving Google private signing keys
Oh yeah it's completely a Google Play policy issue. The original VLC thread on X is titled "App stores were a mistake"
phh··on VLC can't update on Android without giving Google private signing keys
> I don’t get it: app can’t be updated if signed with a new key?

That's correct.

> Given that apps are sold all the time,

I'm pretty confident that in 90%+ of those cases, developers just sell the signing keys with it.

FWIW, Android does have a mechanism to upgrade keys (app signed with the old key contains in its metadata the new key saying that this key is okay) since like 4-5 years ago. But I expect very few people use that. (I don't even know whether Google Play Store allows using this)

> and developers sometimes lose private keys themselves, this makes no sense.

I guess they don't when their revenue relies on it?

phh··on Nvidia CEO Jensen Huang announces new AI chips: ‘We need bigger GPUs’
Thanks. First source i see for what fp4 is. Gotta say I'm surprised: I would have chosen to lose one value, but have a zero. (though I have no doubt those people are much more clever and knowledgeable than I am)
phh··on Apple announces ability to download apps directly from websites in EU
> if the goal isnt reached, there will be enough iterations until achievement.

I wish I was as optimistic as you. GPDR was already supposed to be such an improvement. I have no doubt that current Apple's dance won't work. But I don't think any European company will actually benefit from DMA. (I'd say the ones who will really benefit from it are Epic Games and Google, maybe Mozilla a bit)

That being said, I'm very happy the EU implemented the DMA.

phh··on LineageOS 21 review: Smartphone sustainability starts with software [video]
OEM ROMs that passed Google certifications and everything have been found in the past to:

- Send the content of your clipboard to the internet (OnePlus)

- Disabled SELinux on boot (Asus)

- Allowed any app to be uid 1000, and exploit known for years (Samsung)

- Ignore Linux policy and just picked security-looking patches. And got pwned repeatedly by simply looking at LTS patches. (Google)

As for madaidans-insecurities, they are extremely biased.

Just mentioning microg:

> which allows apps to request to bypass signature verification.

There is EXACTLY *one* app (k k k, two because of Play Store fake too) that bypasses signature verification, and you can VERIFY, which app does it, and WHICH signature it fakes. LineageOS integrated their own microg/fake signature mechanism thanks to Google anti-freedom policy, and you can review their own integration that is even more restricted than what I did (which already is infinitely more secure than what madaidans-insecurities mention): https://review.lineageos.org/c/LineageOS/android_frameworks_...

The final comment in the microg section basically sounds like "oh yeah, that argument could be completely wrong, meh"

phh··on LineageOS 21 review: Smartphone sustainability starts with software [video]
> Can I use my banking software with all the security bells and whistles?

Most custom ROMs(including official LineageOS) are as secure, usually even more, than OEM ROMs. There is just one threat model where it is weaker, which is the evil maid. But it is safer on all the other ones (the evil metro wifi, the evil video, the evil app...). (and personally I take the metro everyday, while taking my shower while I have a maid home just doesn't happen)

As for whether banking apps will work, it's entirely dependant on whether your back is trying to serve their customers or not. Most banks I use work just fine on custom ROMs without hacks. But for instance Google Pay is skimming down on costs, and users pay the price for it.

Can't wait for people to post jailbreaks in reviews

phh··on Dear Linux Kernel CNA, what have you done?
This article largely misses the point from the Linux kernel's point of view.

They have always said "Every bug is a security bug". I don't know about more global content, but at Kernel Recipes (2019?) gregkh took a Pixel that was running latest Google security patches that contained all CVEs. Then looked at non-CVE patches he merged in his LTS. And it took him less than an hour to find a DoS vulnerability.

I understand the author's frustration from the Linux Kernel community to not want to classify bugs, but the reality is that a huge portion of the bug fixes are actually security fixes [1], so between requiring 20% of the patches to be merged, and 100%, is there really a point?

The author mentions Cyber Resilience Act, and I believe that Linux Kernel team created this CNA /on purpose/ to have an impact on the CRA. They believe that the only way to have a secure Linux Kernel is to have an up-to-date Linux kernel. (cf https://social.kernel.org/notice/ARWvggnOvXny0CUCIa ). With the CRA enacted, doing such a every-bug-is-a-security-bug CNA is a way for them to enforce their view.

[1] FWIW, my personal opinion there is that this shows that Linux's monolith architecture is getting old, but I see nothing that could reasonably replace it. I think that "the dream" would be to have a LKL-like linux "arch" to compile every driver as an independent process of Hurd, with GKI-like stable-ish ABI.

phh··on Dell exec reveals Nvidia has a 1,000-watt GPU in the works
Renewable energy does deplete a lot of natural resources. Even assuming it is carbon neutral (it isn't). Even assuming we're still capable of constructing those without fossil energy (we currently can't). Even assuming mining of various minerals is done without fossil energy (it isn't). Even assuming it doesn't require any mining (it does). It still largely requires "natural surfaces" where we have to disrupt local environments. It might be net benefits (offshore wind farms seem to improve diversity), but we have no renewable energy growth that doesn't require first for the natural resources to take a toll.

Don't get me wrong, I do think this is where we're heading towards, and I feel it's okay. But let's not be blind that yes even assuming we go towards fully renewable energy (still a big if, or rather very long when), any growth of energy consumption comes with a cost to natural resources.

phh··on Google Messages RCS is not working on rooted, custom ROM Android phones
I feel like the article's title is wrong: It is not that "it is not working".

It's that Google actively shadow bans users. It's not a bug or anything.

Also, this is not RCS if login requires loggin into Google garden. Let's stop calling it RCS.

I want to say that it's just the strict equivalent to iMessage, but no, iMessage doesn't prevent you from receiving messages, and Apple public communication doesn't pretend iMessage is "standard".

phh··on Company forgets why they exist after 11-week migration to Kubernetes (2020)
Well, that's kinda the point of the point of the joke. There are many people out there more focused on the technology they are using rather than being focused the product they are making. Being focused on the product implies that yes you know your scope, and don't over-engineer it too soon.

The joke concentrates on Kubernetes (if I wanted to be kind, it's probably because a joke is better with an actual examples, but I actually think it's because the author is in that engineering world, and doesn't know the other places where the same applies), but you could do the same with server-side rendering, with AI, with $modernFrontendLib, $modernLanguage

phh··on SuperTux
Well, there actually is/was a Supertux 2. I don't remember the specifics, I think they rewrote it from blit 2D into OpenGL? You can see here : https://github.com/SuperTux/supertux/blob/master/supertux2.d... that it's called supertux2

But yeah this has nothing to do with the actual content of the levels, it only refers to the engine.

phh··on Hallucination is inevitable: An innate limitation of large language models
I think I agree with you (I even upvoted), but this might be an anthropomorphism.

Back like 3-5 years ago, we already thought that about LLMs: They couldn't answer questions about what would fall when stuff are attached together in some non-obvious way, and the argument back then was that you had to /experience/ it to realize it. But LLMs have long fixed those kind of issues.

The way LLMs "resolve" questions is very different from us. At this point, I think that if we want to prove that LLMs need to be rooted in the real world to achieve intelligence, we need to find some real-world phenomenon that is so obvious that noone ever wrote about it... but then we'd have written about it?

phh··on Hallucination is inevitable: An innate limitation of large language models
LLMs are capable as well if you give them access to the internet though
