maven29··on RISC-V chip technology emerges as new battleground in US-China tech war
Really, it's for anyone who's core competency isn't selling general-purpose compute, but will have to design their own ASICs anyway.

For example, when WD open-sourced their SweRV cores in 2019, they also committed to shipping 1 billion copies of the particular design. Beyond just the software ecosystem, they might be looking at incentivizing IP vendors to contribute to a rich ecosystem of interconnects, peripherals, and design/verification software.

maven29··on Nobel Prize in Medicine awarded to Katalin Karikó and Drew Weissman
There aren't a lot of places where going into academia has significant opportunity cost (like for example, losing out on the prospect of a yacht paid for by reactjs work).
maven29··on CISA, NSA, FBI Release Advisory Warning of BlackTech, PRC-Linked Cyber Activity
You are really bringing your own OS here. The nanopi can run mainline linux and u-boot[0]. If you suspect an Intel ME-style component with ring -3 access, it should show up in the initialization sequence - there are no blobs here. Features like these are not cheap to implement, especially when Chinese vendors are so keen on cutting costs.

Essentially, this means that there is zero risk, unless you are a target, at which point any unintentional hardware bug caused by the aforementioned corner-cutting will become a concern.

maven29··on CISA, NSA, FBI Release Advisory Warning of BlackTech, PRC-Linked Cyber Activity
We have photographic evidence of the NSA intercepting Cisco routers. I'm not sure the country of origin matters if you have a red spot painted on your back.

maven29··on Why scalpers can get tickets
If you restrict refunds to be permissible only until a certain point before the event, that will create a window in which unsuccessfully scalped tickets are released back into the pool for general public, bypassing scalpers. If scalpers choose to hold onto the tickets beyond the point, they wouldn't really be able to liquidate. I'd say that we shouldn't let perfect be the enemy of good, with regards to refunds.
maven29··on Why scalpers can get tickets
What is stopping the existence of a refund mechanism there?
maven29··on Yes, Android 14 still allows modification of system certificates
There are ways to bypass any of these restrictions imposed by the Android system, even if they were real. Android ships with eBPF, so you just need root.

maven29··on Ask HN: Why does Google rank the real Python documentation below content farms?
Except those farms don't do any original research and just copy off each other. They're littered with mistakes and you will see the same mistake pop up across all of them.

These days for obscure terms, you don't even get the luxury of reading garbage written by people who barely understand the topic at hand, instead you get meaningless fluff generated en masse using LLMs.

Honestly, I'd rather spend time parsing whatever doxygen spits out than try to figure out what the needlessly verbose yet inaccurate LLM output is trying to get at.

maven29··on Android 14 blocks all modification of system certificates, even as root?
Say hi to ebpf, now shipping with android kernels.
maven29··on UPI Payments: 10B transactions a month done, next stop 100B
QR code still works when either end is low-tech (paper/wearable/sticker), by using out-of-band means (SMS/soundbox) to confirm the transaction.

Further, NFC is usually the first to be left out when manufacturers cut costs to hit lucrative price points.

Apple never implemented host card emulation (HCE) as an API, but that doesn't matter as these payment systems usually aren't backed by a payment card network, thus they'd have to build needlessly complex reconcilliation systems when transactions already debit directly from accounts, and offline usage isn't considered a major use-case.

maven29··on Serial adapter/reboot controller for Apple M1/M2
Why would apple ever release an SBC product? I could understand if a community grows up around repurposing iPhone logic boards, but sourcing their laptop SoCs or boards wouldn't be feasible commercially.

If it's about developing the ARM ecosystem, the Pi boards have systemready certification with ACPI tables and all the creature comforts, with supply issues improving.

As a consumer, a hypothetical Zen4 APU SBC would perform better (7840u) on both performance-per-watt and absolute performance metrics compared to equivalent price M series, while giving you access to the mature x86 ecosystem.

maven29··on Access to knowledge is a human right
I don't think you realize that sale proceeds never reach authors or reviewers. Journals would look like tabloids if they did.

Private corporations even pay for open access because the addressable market for such a product in dollars will be a pittance compared to whatever it cost them to research the product.

Regardless, LLM training has a different notion about the public domain, so trade secrets are what you're looking for - licensing isn't going to stop anyone.

maven29··on Framework Laptop feature requests – RISC-V Mainboard (2021)
East asian vendors like Efinix seem to have high spec parts (with LPDDR4, PCIE4) at low prices and actual availability, without the ITAR troubles you see with US parts.
maven29··on Measuring blood pressure for less than a dollar using a phone
Integrate into wireless headsets? A single-purpose device could have most components on a neckband, otherwise.
maven29··on Did Reddit just destroy mobile browser access?
Every single browser except Chrome would be a better way to put it.

You could emulate the properties of blinking using piezoelectric transducers.

maven29··on New Arm cores deliver up to 40% better performance
Ryzen 7840u is already at par or exceeds M2 performance figures.
maven29··on Windows 11 is so broken that even Microsoft can’t fix it
Enjoy implementing the legal and compliance requirements yourself on linux, then. We live in a society, after all. Enterprise chromebooks are not a consumer product, they are beholden to an entirely different terms of service.

You can either have the desktop linux that is proven to work as a drop-in replacement, or you can have the lab rat version that only works out in engineering orgs.

maven29··on Windows 11 is so broken that even Microsoft can’t fix it
Just issue Chromebooks for the 90 percent if most of the work happens in webapps?
maven29··on What happened with ASUS routers this morning?
Don't they typically have co-extruded copper in the conduit/pipes for Utility Locators to use, even if it's just fiber inside?
maven29··on Google will soon let Pixel phones double as dashcams
A quick search brought up CosyDVR on f-droid. Might not play nice with new Android versions, though.
maven29··on Sorry Purism, I’m not investing. It’s (possibly) not even legal
Nokia sells 4g feature phones in both mediatek RTOS and KaiOS (firefox OS derivative) variants. The latter can run whatsapp, although feature support is a bit behind.

Unfortunately, QWERTY versions would not enjoy the same scale of economy, mostly due to dexterity requirements that would alienate the usual target audience.

maven29··on JanOS: Turn your phone into an IoT board (2015)
When Galaxy Upcycling was first announced, it was extremely ambitious. However, the final product was cut down by a lot to make room for the economics.

https://www.ifixit.com/News/50450/samsung-galaxy-upcycling-u...

To be honest, it sort of makes sense, why would they want to open themselves upto unlimited brand damage liability from battery fires, while spending untold amount of man hours porting mainline linux onto obsolete platforms they'll never see a cent from anymore - whether it be in other products or through services revenue.

maven29··on Microsoft deleted the public support forums for SwiftKey
Car-dependent societies and a complete lack of third places will do that to you, with children being the hardest-hit.
maven29··on Intel Foundry Services and Arm announce collaboration on SoC design
Blackberry phones peaked in 2009, there was plenty of time to reconsider. This is just blatant revisionism, there were plenty of on-ramp opportunities within the product timeline.

Apple didn't move off Samsung entirely until the A8, and they still rely on many Samsung hardware IPs within the SoC to this day. It was not just a fab arrangement from day 1. https://twitter.com/calebccff/status/1472517091970494465

Apple relied on many of the same suppliers as the rest of the industry for a very long time, except the ones they acquired and closed-off. Purely on a "rising tide lifts all boats basis", Intel would still have had access to the dominant player if the ARM-based touchscreen era wiped out the incumbents. However, this is still a very low-margin business, despite requiring more engineering effort than desktop.

You could argue that $1500 phones were unthinkable at the time, but as a commodity, chipset manufacturers see less than 5-10% percent of that, even on flagship phones.

maven29··on Apple’s plunge in PC shipments is steepest among major computer makers
Perhaps non-tech corporations without the means to implement CI/CD would appreciate end-device performance gains?

Regardless, other laptop vendors have mostly caught up in performance anyway. Mobility might have a better case to be made.

maven29··on Show HN: Ermine.ai – Record and transcribe speech, 100% client-side (WASM)
You're only going to be able to do wake-words and command recognition locally on a microcontroller. The maximum external SPI RAM on an ESP32 is 4MB.

maven29··on The ThinkPad X1 Carbon Gen 10 as a Linux Laptop
There are plenty of enterprises that run linux in server farms as well as workstations. You have to remember that Lenovo has plenty of experience with linux this way. They have official ISOs and their metapackages are delivered with distro installers.

Lenovo, Dell et al gets their devices certified with Canonical and Red Hat. OEMs usually work really closely with them.

There is a caveat to all of this - you will only ever be able to run the LTS version for the lifecycle.

With framework, you just hope that they follow intel/AMD reference design to the dot and that intel/AMD gets all the bugs out of the way.

maven29··on Show HN: Document Q&A with GPT: web, .pdf, .docx, etc.
There is no waitlist anymore, and this functionality is delivered through the Bing sidebar.

Internally, it has the same privileges as a third party extension with webpage content access, so it cannot access the pdf viewer contents. I believe Edge is getting a new PDF viewer in Canary that might solve this. For now, you can select text 2000 characters at a time and send to chat or give it a URL (assuming that Bing can see it in the search index).

Bing chat is already good at handling recursive queries (with internet access) and processing poorly formatted PDFs from the indexer webcache, so I assume it would do well given the right conditions. It does Q&A really well on GitHub repositories, for example.
