@notch These things are equal. The former is a Turing machine and the latter can implement the former.

A finite state machine with infinite tape is the same as an infinite state machine with finite tape. No, I haven't proven it formally. This is more of a vibe computer science moment. If I'm wrong and someone has actually studied computer science, I would love to learn more!

TIL libc provides a weird useless function called "index". I discovered it by renaming a local variable "index" (reasonable name for a variable) and having my code successfully compile but with a warnings saying "dude, you are comparing int to a function". And I was like wtf.

At this point I have put nearly Counter-Strike amounts of time into this game. ('nearly' because at one point I estimated I had played 2000-3000 hours of CS.)

Last fall, I made a chip on TSMC's 65nm process, with funding provided by @Apple. Myself and my group made a Course Grained Reconfigurable Array with timeshared RISC-V cores, all fitting on a 1mm^2 die. We have open sourced our project for people to view (link in thread).

Reminder that Epic is a privately owned company, who struck lightning to gain unholy levels of cash flow, and still barely compete with the Steam platform. Their best attempts to compete were to sign exclusivity deals which brought hate to the platform instead of users...
Tim Sweeney@TimSweeneyEpic

@BenjiGameDev Not true. I just hate to see Valve confiscate ever more opportunity from small developers by facilitating new categories cancel campaigns and review bombing. Steam used to just facilitate downloads. Then they foreclosed on payments, then price competition, then crypto, now AI.

When the submission form for a recommendation letter for grad school asks you in what languages the candidate is fluent in, the right answer is "all of them". FYI.

Amazing things happening at the @andrewcuomo rally. Old white guy rallying people in anger (the opposite side of this poster blames silwa for stealing the election)

Good Edtech is a selfless job. You fight the underlying thread that education should be free, especially decentralized options. All of these platforms farm users for money and attention and when Gagan's "edtech 2" comes out it'll be a $100/mo AI TA grading your work...
Gagan Biyani 🏛@gaganbiyani

The dirty little secret of edtech: the biggest names don’t actually care if you learn anything. As co-founder of Udemy, it is something I reckon with every day… Duolingo - edtech’s only decacorn, worth $14B. Brilliant app, addictive product, and great for motivation. But let’s be honest: most users can’t hold a basic conversation in their chosen language. It’s a game, not an education. Masterclass - it’s called “edutainment” for a reason. Great brand and team. But not useful for serious learning. Udemy/Coursera opened access to millions, but video courses have a fatal flaw: they only work for the most motivated. 4-10% completion rates! I still get DMs about their positive impact, but still average person doesn’t view them as mainstream solutions to education. Kajabi/Teachable nailed creator monetization. But many (not all) creators don’t prioritize outcomes — just sales. Too many $5,000 “get rich quick” courses with spammy marketing. There are gems, of course, but still not enough quality for mainstream acceptance. Then there’s University of Phoenix, the worst offender. It proved you could tap federal student loans, deliver poor outcomes, and keep billions in revenue. Ironically, the best education models — coding bootcamps like App Academy, BloomTech, General Assembly, Galvanize — actually drove real outcomes. But they didn’t quite reach scale. In large part due to unfair (and immoral, imho) practices by the higher education cartel. Here’s the thing: everyone in this space starts with good intentions. I know the teams at Duolingo, Udemy, and others. They care. But the incentives of Edtech 1.0 pushed everyone toward engagement and monetization instead of real learning. Public investors eventually caught on. Consumer growth stalled, B2B slowed, and valuations dropped. Coursera/Udemy are each ~$700M (!!) in annual revenue, but trade at 1.5-2.5x multiples (!!). It is a hard time in edtech. We need Edtech 2.0. The next generation needs to deliver real learning outcomes AND high engagement. There’s a number of companies trying - of course I believe Maven is one of them. To build multiple $10B+ companies in education, we need to care deeply about whether people actually learn. American competitiveness is literally reliant on rebuilding our education system. AI is about to trigger the largest upskilling need in modern history. The opportunity is massive — and this time, we can get it right. It may not seem like it, but I’m optimistic. Out from the ashes of Edtech 1.0 will rise Edtech 2.0. The new generation is going to deliver value, and make people believe again.
