"I view the proliferation of Halloween skeleton sizes through first edition AD&D monster manual heights: X - kobold X - goblin X - orc XX - ogre XX - stone giant. Waiting for the competition between Lowes and Home Depot to bring a storm giant"

"Teslas displaced my exotic cars many years ago but with the Roadster still an indeterminate distance in the future I had been feeling an urge for something a little more analog. I was initially thinking about a 60s Camaro with modernized running gear but a part of me was also nostalgic for my old MGB. I eventually remembered that there was a car right at the intersection of muscle car grunt and British roadster charm the XX Shelby Cobra. It is kind of amazing that the federal Low Volume Motor Vehicle Manufacturers Act of 2015 authorizes small runs of replica vehicles to basically ignore all"

"The premise of the Ring of Fire books is the transportation of a modern West Virginia town to 17th century Europe and I have been enjoying the alternate history quite a bit. They arent for everyone; the first few chapters of book X revolve around an industrial accident in a petroleum refinery cobbled together from 17th century tech which probably doesnt meet the literature bar of many. Beyond just fun I find them wholesome. It is obviously about the power of technology but also organization and ideals and it points out pockets of high competence existing in every time and place"

"Im sad to see the glee that some on the right have at the opportunity to deploy cancel culture over post-assassination-attempt comments. Im a hard core free speech advocate and I look at it like germ warfare its bad for the whole ecosystem. People like to think that they would fight and die for their sacred principles. This is low stakes practice. The actors will say THOSE arent MY sacred principles Im going to punch back at my enemy but to the people at the margin Maybe the principle is important to you Maybe you shouldnt cheer for an online mob"

"My distracting thought for the morning is that you could have actually made a decent rhythm game on X bit Apple X hardware but I dont recall any examples. Screen presentation and effects would have to be minimal and you wouldnt get any high fidelity audio but you could totally do a drum simulator with sub millisecond accuracy and response time from an interleaved polling and speaker drive loop. Combined with all of the game engagement mechanics that dont require much processing it could have been compelling. XX years ago"

"An early version of the mega texture processing for Rage used GPGPU but it was hard to maintain and unreliable across a heterogenous set of workers so I eventually went to a purely CPU architecture. I only started CUDA programming after we were too deep in development to warrant a change"

"The scrolling console has been a valuable paradigm since physical teletypewriters in the 60s and millions of programs have coded directly to that interface. It feels like we missed a sweet spot in output options just beyond that. There are many times I use a jupyter notebook just because I want to print some images and I wish I could instead have traditional console programs write a simple escape sequence header and dump X bit RGB image data to the terminal. Some terminals like Kitty do offer image capabilities but chunking and base64 encoding the data takes it from just print to import and"

"Starlink announced a $5/month plan that gives unlimited usage at 500kbits/s. Modern apps and web pages would immediately back up every buffer and make for a painful experience but it is fun to consider optimizing inside that tight box (in the 90s 4x ISDN was high end). With Starlinks good latency input-distribution multiplayer games would still work fine as long as they didnt download anything. You could even have voice chat. With an optimal implementation you could scroll the X feed as fast as you want with full text with progressive images coming in when you pause but instantly ceasing"

"I recently learned about Cayley transforms. Similar to how you can parameterize a 3x3 rotation matrix by X Euler angles or a X element quaternion Cayley transforms allow you to parameterize an N dimensional rotation matrix with just N*(N-1)/2 unique values in a skew-symmetric matrix saving more than half the parameters and guaranteeing that the matrix will always be orthogonal. Unfortunately the transformation involves a linalg.solv() or pinverse() so it gets slow with thousands of dimensions. Still I am happy to have this in my mental toolbox now"

"I expect AI to produce a lot of value while trying to make a coherent body of knowledge out of its training data but on its own AI is limited to a sort of ancient Greek philosophical process where the method is rhetoric rather than the experimental process of science. This has always been one of my gripes with the AI doomer crowd even infinite intelligence cant derive all of physics let alone biology or sociology from first principles. In a finite completely specified environment like Chess or Go you can indeed keep diving deeper and deeper with nothing but computation. Relatively few"

"Anyone here on the Amazon Kindle iOS team For ages now the iPad kindle app has locked up for many seconds at a time when downloading large media files. Maybe a second or two wasnt considered a big deal for downloading a book you are going to read for ten hours but when you buy a half dozen or more large file size comic books every week it grates. Long ago it didnt behave this way and you could interact freely while multiple files were downloading. Someone broke it"

"Numpys fromfile()/tofile() make me smile no typing or byte order metadata they just write/read the raw bytes. A joyful API I wish PyTorch had them natively on tensors so I wasnt doing so many tensor.cpu().numpy() operations"

"I had been meaning to comment on @Jonathan_Blows Why cant we even conceive of writing a new OS today post. Coincidentally I just got an email that opened with: Hey John X years ago I pitched you LIBBA - a dedicated OS for smart glasses. You were sceptical your main concern was that a custom OS rarely justifies itself: cost shelf life and developer burden outweigh the benefits. You were right. I deeply love the ideals of clear efficient programs that do their job without baggage and I have always been very sympathetic to efforts like Oberon Plan X and even TempleOS. But building a new"

"I think you are misunderstanding what this tech demo actually is but I will engage with what I think your gripe is AI tooling trivializing the skillsets of programmers artists and designers. My first games involved hand assembling machine code and turning graph paper characters into hex digits. Software progress has made that work as irrelevant as chariot wheel maintenance. Building power tools is central to all the progress in computers. Game engines have radically expanded the range of people involved in game dev even as they deemphasized the importance of much of my beloved system"

"I helped fund the restoration of an old IBM S/34 and now I find myself occasionally thinking about what realtime games you could make run on a 5251 DisplayStation. Tetris would probably be the most engaging. Not sure if you could do it in RPG or COBOL; might require S/34 Assembly"

"It is nonsense to suggest you cant write any app of any complexity in C. I do find a light level of C++ beneficial for many larger projects but it can also go tragically wrong. Sometimes specific language features can be transformative valuable but not nearly as often as language advocates think and there is value in writing to an elder language"

"Sometimes I see papers with hyperparameter sweeps over XXXXX XXXXX XXXXX XXXX etc. Many hyperparameters are better expressed in negative integral log2. Small values like learning rates directly and values close to X like EMA factors and TD lambda / gamma with 1-2**val. It is interesting how many parameters are relatively insensitive to doubling or halving and need bigger changes to reliably move the results"
