StringyBob··on Havana syndrome: 'directed' radio frequency likely cause of illness
I can possibly believe it, just because similar RFID using high power sources are known about, from the original ‘the thing’ by Theremin in 1945, to stuff exposed by Snowden like https://www.schneier.com/blog/archives/2014/01/ctx4000_nsa_e... and https://www.schneier.com/blog/archives/2014/03/ragemaster_ns... However, any potential substance to this will always get lost behind the anti-5G tinfoil brigade, let alone propaganda and spycraft, so we’ll never know the truth.
StringyBob··on IoT Unravelled Part 2: IP Addresses, Network, Zigbee, Custom Firmware, Soldering
I’ve found the initial zigbee pairing more and more painful as the number of IoT devices in my house increases. Although normally a one-off at installation, with lots of devices present don’t expect it to work first time.

Occasionally when encountering bugs in various software/hardware combinations i have seen suggested fixes of ‘just re-pair everything to a hub’ which for a full house will take a day and drive you insane.

One additional concern is the environmental impact of the number of cr2302 batteries in use - one for most switches and sensor that aren’t permanently wired in - even with a 1-2 year battery life it adds up to a lot. I think firmware updates in current systems take a big bite out of theoretical battery life spans.

StringyBob··on Pro Rata and User Centric Distribution Models: A Comparative Study (2017)
It’s worse than that, because as a paying subscriber you are subsidizing listens coming from free/ad-supported accounts too.

In fact, other users take away your money from artists you like if they are a heavier user of the service than you - as they get more of the total pot in current system. From the point of view of the big labels who have control this is a feature not a bug. http://www.serci.org/congress_documents/2019/user_centric_re...

StringyBob··on Pro Rata and User Centric Distribution Models: A Comparative Study (2017)
I’ve been very interested in the user-centric model described, but I’m not aware of any streaming services using it. What are the chances that Spotify would make this an option? Even if it was just opt-in, that we go a long way to keeping me with them as a premium subscriber.
StringyBob··on Spotify Is Defending Alex Jones' Appearance on “The Joe Rogan Experience”
I’ve been a Spotify premium member for over a decade. I love their service for listening to and discovering music. I don’t want to be contributing to over-inflated ‘exclusive’ podcaster salaries that I never listen to.

In previous feedback to Spotify I’ve asked for a ‘hide podcasts’ option in the iPhone app. It’s unwanted clutter I don’t use.

Time to redirect the money I pay to the artists I listen to. What systems would others recommend?

StringyBob··on XFS File-System with Linux 5.10 Punts Year 2038 Problem to the Year 2486
A bit mysterious, but seems as files will now have nanosecond accuracy since 1901 (in the 64bit unsigned int), the quota timers are still 32bit and have been downgraded from 1 second to 4 second accuracy to cover the full bigtime forward time range required (for 1970 unix epoch).

Seems to be described in this patch comment: https://patchwork.kernel.org/project/xfs/patch/157784114490....

StringyBob··on Chromecast with Google TV
Tempted by the offer being open to existing subscribers, but seems odd they are selling a 4K/HDR supporting device, but not offering a 4K based plan!
StringyBob··on Spotify reportedly fighting with employees about hosting episodes of Joe Rogan
As a Spotify premium subscriber, I don’t particularly like that a chunk of my subscription is going to their ‘exclusive podcasts’, while musicians I listen to are getting minimal payouts. I’d be much more comfortable with my subscription being split amongst the things I choose to listen to.

StringyBob··on Spotify CEO: musicians can no longer release music only “once every 3-4 years”
Here’s an example of what some artists want: https://www.musiciansunion.org.uk/Home/News/2020/Jun/An-Upda...
StringyBob··on Spotify CEO: musicians can no longer release music only “once every 3-4 years”
There is a gut feeling that indies and up-and-coming artists are losing out with their fans effectively subsidizing pop that gets more ‘disposable’ plays.

I’m sure Spotify will know the numbers for moving to user centric streaming payouts, would be very interesting to know the truth of who the winners and losers would be.

There’s a bit of info and some research here: https://musically.com/2020/05/13/what-are-user-centric-music...

I think the option to be user centric could be a compelling feature for premium customers, to show money is going to artists fans love, and ultimately move more people on to the premium versions of streaming platforms

Personally at this time I’m more concerned that my Spotify subscription is subsidizing podcasts by Joe Rogan than Drake / Taylor Swift.

StringyBob··on SkyWater-PDF Plans First 130 Nm Wafer in 2020
At 130nm, you could fit at least a couple of 68k’s worth of logic in a square millimetre of silicon. The limitation is you can’t fit that many IO pin connections on a chip so small (pad limited). You might as well chuck in the rest of the Amiga while you are there!

Unless I’m missing something this is jumping the gun slightly. It looks like an empty document template with a few placeholder titles. It doesn’t actually contain any design rule information.

> It is estimated that the one-half of the round-trip delay happens in each direction.

Anyone know how true this is? Particularly for mobile/asymmetric bandwidth connections - what might the errors bars be?

> what they've ditched is cache coherency. That certainly makes it simpler to implement but now the cores have to be responsible for their own coherency.

Like the quote says: “There are two hard things in computer science: cache invalidation, naming things, and off-by-one errors.”

StringyBob··on Faults in Post Office accounting system led to workers being convicted of theft
Whenever I hear about large outsourced IT project disasters in the UK I go to check ‘computer weekly’, and sure enough, they’ve been investigating this for well over a decade

It’s the same large IT contractors whose names seem to come up again and again in these public cases

StringyBob··on LA getting serious about lifting parking requirements in downtown
Where I live (not in the US) we have parking maximums, not minimums.

A new office development will not get planning approval if it has more than 2 parking spaces per 3 employees (based on some obscure measurement of building capacity). This is to reduce congestion and encourage more environmentally friendly methods of transportation.

StringyBob··on The First Sony Walkman Was Released 40 Years Ago
Although The Walkman was released 40 years ago, Sony had actually made something that will look familiar another 10 years earlier and was used on Apollo moon missions: https://airandspace.si.edu/multimedia-gallery/5254hjpg https://www.sony.net/Fun/design/history/product/1960/tc-50.h...

Incidentally, I only discovered this recently after hearing the Apollo 11 astronauts use one to play a prank on mission control while on the way back to earth. You can hear this at the amazing https://apolloinrealtime.org/11/ (definitely works best on desktop not mobile)
