bytesmith··on Math, Physics, and Engineering Applets
Looks like he used swingjs[0] to port the applets to javascript since it hasn't been possible to run Java applets in a Chrome since v45 circa 2015. Always nice to see web 1 code live on.

bytesmith··on Tesla Fleet Telemetry
Based on the message spec[0], it doesn't look like this can be used to track Full Self Driving disengagements which is a shame. However, for its intended purpose which is presumably to help 3rd parties (eg Hertz) manage fleets it seems like a boon.

bytesmith··on National Geographic lays off its last remaining staff writers
That’s basically the model of Apple News Plus, although it’s Apple ecosystem-specific. Users pay 10$ a month to get access to selected publishers via the Apple News app and then Apple takes 50% of the subscription revenue and splits the rest with publishers based on the number of times an article is read[0]. I don’t think it got any significant traction though as I haven’t really heard anything about it since it was launched 4 years ago.

bytesmith··on Ask HN: Meal Planning App?
I also use this. It's the best recipe collector website/app i've found (there's a chrome extension and the parsing is excellent). It also supports all the features you want, like meal planning[0] and shopping lists[1] for free but you can get more powerful capabilities with a modest subscription fee.

bytesmith··on Shimano Forces Hammerhead to Remove All Di2 Related Functionality From Karoo
No there are many different manufacturers including SRAM which now owns Hammerhead but Shimano does have about 70% of the marketshare.
bytesmith··on Show HN: Django SQL Dashboard
I use Django SQL Explorer pretty much every day. It's been wonderful for my needs. I'm also very happy to see django sql dashboard as an alternative and in particular the dashboard features like vega chart and markdown integration. I will definitely check this out. Thanks to both of you!
bytesmith··on Apple Introduces AirTag
I use a cheap rubber case for my AirPods that has a little loop for a keyring that I use to attach a Tile to [0]. It's a little bulky compared to the naked case but it has a few of advantages.

First, it allows you to say "find my AirPods" to your phone and the Siri shortcut will launch the tile app and ring your AirPods. Second, the silicon is really grippy so it's far less likely to fall out of your pockets, and third the keychain ring means I can store it on a keyhook by the door which is my system for not loosing my keys in the first place, and usually obviates the need for the Tile:)

I do agree that having the UWB transmitter built into the case would be better provided it doesn't require the case having charge to work, which isn't always going to be true.

bytesmith··on GM recalling nearly 69,000 Bolt EVs for fire risks
They didn't change suppliers they changed the chemistry to provide more range [1]

bytesmith··on Building all of our new mobile apps using React Native
They will probably slowly introduce the changes one feature at a time in a backward-compatible way in a similar manner to how core react architectural changes are introduced (eg fiber, suspense, hooks etc).
bytesmith··on Building all of our new mobile apps using React Native
There is a major re-architecture of React Native underway[1]. See Lorenzo Sciandra's excellent conference talk for an explanation of what the current limitations are in React Native and how they are planning on addressing them in the near future [2].

bytesmith··on Bontrager’s WaveCel material more effective at preventing concussions than MIPS
The study cited is questionable. The best independent source for helmet testing IMHO is virginia tech's, which show that these are about as effective as MIPS, not 98% better as the headline suggests:

Here's their methodology:

bytesmith··on LEGO built a life-size, drivable Bugatti from over a million Technic pieces
It’s not quite as fast but in my opinion the Ferdinand GT3[1] is a much cooler vehicle.

bytesmith··on CeramicSpeed’s Driven Concept Might Become the Most Efficient Bicycle Drivetrain
It's just a concept. CeramicSpeed have said they would like to partner with someone to design the shifting mechanism[1].

bytesmith··on CeramicSpeed’s Driven Concept Might Become the Most Efficient Bicycle Drivetrain
Unfortunately, Pinion systems haven't really gained any significant market share due to a) really high cost b) inability to downshift under load, c) a 1.5lb weight penalty and d) the frame must be built specifically for the Pinion system[1]. Still, always great to see new approaches like this as bike maintenance is a huge barrier to adoption.

bytesmith··on Google Treks
See my link below for an Oculus demo using 360 degree cameras. It's doesn't feel nearly as fluid or 3D as the other Oculus demos, but it's promising nonetheless.
bytesmith··on Google Treks
I hope they render some of these for the Oculus. Making View, a Norwegian company with similar 360 degree camera technology has released a few Oculus demo clips of people doing amazing things with their cameras. http://makingview.no/makingview.com/?page_id=1691

You can effectively disable the restart all applications behaviour by doing this: http://osxdaily.com/2011/08/25/disable-reopen-windows-when-l...

It would be nice if there was a proper system preference though.

bytesmith··on Building iPhone Apps with HTML, CSS, and JavaScript
It's worth noting the response to O'reilly's own Safari To Go iPad app on the Safari Books online blog which was based on PhoneGap. The app has since been pulled from the App Store. See http://safaribooksonline.wordpress.com/2010/11/24/ipad-app-s...
