I don't know about anyone else, but when transitioning back to a shell, I HAVE to hit a bunch of enters on any prompt to clear the last output away a few lines before I can summon up the powers to enter a new command - blow away the cobwebs and all that. I love the empty enter command line :)

Great article - enjoyed it a lot!
re: the notes on the use of the device keys (stored in the K/V store), assuming that they are per device would seem the most obvious vs that they are global. Global keys would be written in the main app body in my experience, not the KV store (but that doesn't mean people have not done unusual things here of course!).
I also want to share some feedback on the complexity of managing per device keys these days and the risks - there are lots of easy to use tools that per device keys like this much simpler to do in 2025 than 2015 and cloud platforms that take in CSV files and return very similar messages... Typically a security model for a device such as an air purifier can be easily defined as not having device encryption enabled if it has per-device keys on as the impact of breaching a single device remains compartmentalized to a single edge component and in this case, just a purifier (vs a car or something that explodes!). Not that I agree with this, but corporate security can! Device encryption causes lots of problems in factories that are often best 'ignored' if the product can afford it.
Per another comment, god bless ESP32 developers once the EU rule kicks in in August... !

I've heard it all before, both of these are simple to refute. Apple designed the USB-C connector, they knew it was an option. But as is Apple tradition, they created a new licensed serial and power connector specifically for their phones to promote MFi, their arbitrary USB DRM. Apple could have switched to USB-C at any time; they had no issue shipping millions of peripherals and Macs with them onboard. But they didn't, because then they couldn't foist a proprietary standard onto their most lucrative submarket.
> If you want another App Store just by an Android phone since that's a feature they offer.
Sorry, this is bullshit. Alternative sources for installing software will always exist, even current iPhone users have to accept Cydia as an option. You don't ever have to leave the Apple App Store, but your preference has no right to enforce an artificial limitation onto other users. The Mac as a product would not exist without third-party software distribution, the iPhone is undeniably stifled by Apple's stance on the matter.
Lightning development started in 2008 as I was there!
USB-C development started in 2012 (I was not there!), but from wiki, the ever helpful source of truth: "The design for the USB-C connector was initially developed in 2012 by Intel, HP Inc., Microsoft, and the USB Implementers Forum. The Type-C Specification 1.0 was published by the USB Implementers Forum (USB-IF) on August 11, 2014.[1] In July 2016, it was adopted by the IEC as "IEC 62680-1-3".[3]"
I not sure of the logic here, but Lightning solved a problem way before USB-C existed and I'm sure, led to support of USB-C standards such as reversible connectors etc...

This was written by AI.
In the spirit of tech conversations, here was my original input from my history:
---
I was swept up in this article and the portrait for Amanda (barrows) - what a unique and strong person - this city is soo lucky to have her.
I want to respond that unlike some here, I came away with huge empathy and today's HN snark and frustration bounced off me pretty hard accordingly. The public order issues such as homelessness in the park have impacted me, but more so, how to translate the state of the world to my children. I always remind them that this person was once a little boy / girl and we might be older, but we're still kids inside and nobody dreamt to grow up in this environment.
The compassion and my own empathy shown here coupled with the pragmatic approach shown by Amanda washed over me and the policies and bureaucratic inefficiencies that make solutions slow and ineffecient are understandable, but also highly frustrating.
The unhoused individuals and their mental state vs the requirements to find a home are very frustrating - the city surely understands the cost of housing policies and is run by highly pragmatic people, but rules are rules and some top down accommodations and medications are needed to help merge this.

I personally don't see my opinions changed here - I think the posted text is a bit better but also agree on the uncanny valley issue. A little less brain swelling and I would have been all over the small signals :)
Personally, I find AI and the derivatives extremely helpful when it comes to communication (a booster for the mind!) and use it all the time when translating into other languages and also removing my northern British dialect from communication over in California.

I was really swept up in this article and the portrait of Amanda Barrows - what a unique and strong person and this city is incredibly lucky to have her.
Unlike some here, I came away with a deep sense of empathy, and today’s HN snark and frustration bounced off me pretty hard. The public order issues - homelessness in parks, the challenges of shared spaces—have certainly impacted me. But more than that, I struggle with how to translate the state of the world to my boys. I always remind them: every unhoused person was once a little boy or girl. We might be older now, but we’re still kids inside, and nobody dreams of growing up in these circumstances.
What struck me most was the balance of compassion and pragmatism that Amanda brings to her work. It’s easy to be frustrated with the policies and bureaucratic inefficiencies that slow down real solutions - but they are, in some ways, understandable.
The biggest frustration for me is the gap between the mental state of many unhoused individuals and the requirements needed to secure housing. The city surely understands the long-term costs of its policies, and it’s run by highly pragmatic people with limited budgets. But rules are rules, and at some point, top-down accommodations (including medical interventions...) are necessary to bridge this gap.
So the ARM v. Qualcomm litigation and the business moves preceding it seem to basically be hardball license contract negotiation via lawsuit. Qualcomm is by far ARM's largest customer and the ARM license is fundamental to Qualcomm's CPUs. Neither can really afford to live without the other but for both, significant business and strategic value is tied to getting more per core (ARM) or paying less per core (Qualcomm).
I suspect that eventually they'll end up settling with each other once the court case gets to a point that narrows the probable range of the outcome (thus creating the approximate upper and lower boundaries to negotiate within).
I'm sure that the lawyers decided that ARM must enforce its licenses, especially when a license holder has explicitly violated the terms in a public fashion. If they don't at least automatically try and enforce their position through legal processes, ARM risks devaluing their IP and losing future negotiating power and give.
I'd be surprised if there was anything but cold hard contract negotiations going on behind the scenes that will shortly end in an amicable settlement and another 10 years of ARM based QCOM chips.
mrlambchop commented on Romram: Using QSPI RAM with RP2040's SSI in read-write mode dmitry.gr/?r=06.%20Though... · Posted by u/fanf2
I recently worked on a product (Realtek 200MHz MCU + integraiton wifi/ble) that had a similar setup - QSPI connected PSRAM and QSPI connected Flash (with read/write).
The PSRAM had a reasonable size page cache in the chip that made this memory quite responsive from a CPU perspective - a few rare cache flushes were needed, but things like DMA and bus masters (onboard radios etc..) were completely coherent and it made development much easier to manage.
My takeaway was that PSRAM was surprisingly capable (with the right can of hardware controller in place). Kudos to Realtek for getting the hardware to work without a thousand impossible to debug CPU lock ups...
