@BenjaminDEKR Or you could use something you already have!

Like an Apple TV remote.

Or a Dualsense controller.

Or an Xbox controller.

Or a Switch Joycon.

Or a Steam controller.

Or an 8BitDo controller.

YouTube iOS client has dark mode/light mode issues with font color.

I thought it might be fixed by now, but I’ve dealt with this for about a month now. Force restarting app fixes it.

Please file bug report.

Why are happy customers buying ControllerKeys?

ControllerKeys customizes your game controller to do anything a mouse and keyboard could do! And more!

A lot of professional software can be used more handily with the help of ControllerKeys.

What’s your favorite Easter egg on modern devices? Do they even do anything like this anymore?

The closest thing I can think of is tapping to activate developer mode on Android.

@applefiles_ Play Brick by going to ‘Settings’ then ‘About’ and then hold the centre button for five seconds.

There’s a hidden dagger in almost every PC game from 1995-2005 that murders ARM processors.

It’s kind of an accident, and it all has to do with floating points.

x87 was Intel’s floating point extension to x86. I won’t get into all the historical drama, but Intel decided that all internal float math would be at 80-bit extended precision to reduce rounding errors.

Of course, today no one in their right mind uses 80-bit; standard 64-bit doubles are just too convenient. Modern ARM64 doesn’t have any 80-bit hardware!

This creates a nasty problem for emulation. How much x87 arithmetic can you replace with say, native ARM64 floating point (losing precision!) without breaking behavior?

It’s not so simple; dropping 16-bits of precision can cause funny physics glitches and such. But boy, if you need all 80-bits, the software fallback REALLY stinks.

With all the decomp/recomp hype lately, porting OG Xbox and PC games to mobile / ARM devices is extra tricky. Not impossible, but you’d be amazed at how much x87 code is in old games!

Oh my goodness this has to be right.

Instead of generating a random 256-bit number they generated a random number between 0 and 256.

That’s how they got 4, 66, 155, 156, 230 and 237.

@pimanrules Interesting I’ve never heard of this.

How’s that work? Does it strengthen some connections in there?

@RobertDaleSmith I’d love to see it drive a Mac!

I’ve been working on this https://t.co/B2dvPh1guV

@RobertDaleSmith The younger sibling controller 😆

Very cool!

[Kevin Tang @_KevinTang]

The Steam Deck can get pretty much all past generation console games running on it!

I was shocked. Ask your AI agent about it.

[Kevin Tang @_KevinTang]

@Deivid11 It’s way more suitable for travel IMO. More portable and less heat output.

I’d recommend trying it out if you’re just looking for a screen on your face!

Playing some Cyberpunk on the plane with my XREAL glasses!

Back and neck feeling real good after a long flight.

@shujishcn I’m sold! Take my money! 😅

@NaderLikeLadder With only the AirPod data

[Kevin Tang @_KevinTang]

@NaderLikeLadder Such a cool idea!

I’m wondering how you will distinguish when the pencil is actually touching the screen and writing vs just floating in the air. That seems like a tough thing to distinguish.

Came across the awesome security camera comparison display from TP-Link at the Syntrend Mall!

I’m sure someone had a fun time putting together this demo.

Got Cyberpunk on Mac!
