@WadjetEyeGames I've just played and finished the Blackwell series. And they were *awesome*, start to end. Some parts were gut wrenching. Some parts I cheered. At the end I gave a standing ovation to a computer screen. #VideogamesAreArt #Blackwell

@Cmdr_Hadfield @NASA Always thought of T-38's as one of those 'if it looks right it flys right' aircraft that just wants you to take it up and throw it around. Really sleek area-rule'd fuselage, prettier nose than the F5, fast-jet distilled + the NASA blue-stripe livery 😘

@AntonHand I always find that, it's like I some how save up being sick until I take some time off, then instantly BAM

@kylegriffin1 Can't wait for the second case to also eventually be finalised through the appeal courts, then he'll hopefully have to pay the $83m defamation suit

@MikeTappTweets @ZackPolanski There's something wrong in your heads if you think this was clever. You're an absolute insult to everything the Labour party used to be and stand for.

You should be fucking ashamed of yourselves. I expect this sort of toss from Reform, not from the government.

[Alex Walters @CaffeinePwrdAl]

@PolitlcsUK Grim tbh

@DiscussingFilm Maybe it false triggers too often, or it's latency loading the sound - but it should play when it detects 0g on the accellerometer and not registering capacitive touch so it screams on the way down not when it lands 😂

[Alex Walters @CaffeinePwrdAl]

@georgebsocial Just finished playing and I utterly concur - great game, really liked some of the card mechanics and loved the late 90's early 00's FMV horror stylings and PC Magazine callbacks :D

@EdKrassen I've got a plan to fund NASA...

@cryptovegan @DJSnM https://t.co/Kx5Racc9Qh shows the EXIF. 1/4s, 52100 ISO f4

[Alex Walters @CaffeinePwrdAl]

@KyleHollSays @DJSnM From NASA's website where they show the EXIF data, 1/4s with an f2.8 lens. Though with an ridiculously high ISO, hence the noise when you zoom in.

Probably should get them something with a better f-stop :D

@_MaxQ_ Also love the shock cones in the RS-25 exhaust

[Alex Walters @CaffeinePwrdAl]

@_MaxQ_ At first glance you don't see what it is, just a moody shot - and then you realise the beast in the back of the frame - great accidental shot

[Alex Walters @CaffeinePwrdAl]

@DeltaWave0x Bake material parameters into all the shader variants + multiple shaders for different passes. I've seen some projects compile 800k PSOs. And still need to compile more when streaming.
I sometimes think they're shipping the whole undo-buffer history of every shader in the game

Kerbal Space Program has an April 1st Easter-Egg.

Respect 💯

@castano Should also note that lossy fb compression is less designed as a texture-compression system, and more typically designed for use in bandwidth reduction between the GPU and display controller. A good ASTC/BC encoder should generate much better results for textures

[Alex Walters @CaffeinePwrdAl]

@castano When not using lossy compression modes, lossless will be applied by the driver whenever we can, which will reduce some bandwidth.
Did your analysis specify VK_IMAGE_COMPRESSION_DISABLED_EXT for the uncompressed image runs?

@Sosowski The White House doing PR for you now? Epic!
