Google, DuckDuckGo massively expand “AI” search results
Clearly, online search isn’t bad enough yet, so Google is intensifying its efforts to continue speedrunning the downfall of Google Search. They’ve announced they’re going to show even more “AI”-generated answers in Search results, to more people. Today, we’re sharing that we’ve launched Gemini 2.0 for AI Overviews in the U.S. to help with harder questions, starting with coding, advanced math and multimodal queries, with mor … ⌘ Read more

↳ In-reply-to » I'm in an article in Quanta Magazine! It's about the bizarre world of algorithms that re-use memory that's already full. https://www.quantamagazine.org/catalytic-computing-taps-the-full-power-of-a-full-hard-drive-20250218/ I'm the one with all the snow in the background.

@lyse@lyse.isobeef.org I am a big fan of “obvious” math facts that turn out to be wrong. If you want to understand how reusing space actually works, you are mostly stuck reading complexity theory papers right now. Ian wrote a good survey: https://iuuk.mff.cuni.cz/~iwmertz/papers/m23.reusing_space.pdf . It’s written for complexity theorists, but some of will make sense to programmers comfortable with math. Alternatively, I wrote an essay a few years ago explaining one technique, with (math-loving) programmers as the intended audience: https://www.falsifian.org/blog/2021/06/04/catalytic/ .

Pinellas Trail Challenge: 36.30 miles, 00:14:47 average pace, 08:56:28 duration
DNF’d, but had a great time! i could have walked it out the last ten miles and still made the cut-off but after doing the math i would not have been done until about 1900 and we had guests visiting from out of town and i did not want to be even more of a wreck while entertaining. met a lot of great people and happy for the challenge.

Where’s the Calculator on iPad? Use Spotlight!
Calculators are wildly useful tools for various obvious reasons, whether you need to perform simple math or complex calculations. One of the more curious iPad oversights on Apple’s behalf is the lack of a built-in Calculator app, which is missing on iPad, but has been included on the Mac, iPhone, and Apple Watch, since the … Read More ⌘ Read more

@movq@www.uninformativ.de Haha! yeah sounds about like my HS CS program. A math teacher taught visual basic and pascal. and over on the other end of the school we had “electronics” which was a room next to the auto body class where they had a bunch of random computer parts scavenged from the district decommissioned surplus storage.

The advanced class would piece together training kits for the basic class to put together.

Golang 如何有效限制併發數？
Go 語言目前很火熱，一部分原因在於自身帶 “高併發” 的標籤，其本身就擁有優秀的併發量和吞吐量。1 協程可以無限創建嗎？我們在日常開發中會有高併發場景，有時會用多協程併發實現。在高併發業務場景，能否可以隨意開闢 goroutine 並且放養不管呢？畢竟有強大的 GC 和優越的 GMP 調度算法。看下面的代碼：package mainimport (    ”fmt”    ”math”    ” ⌘ Read more

↳ In-reply-to » I used to be a big fan of a service called cocalc, which you could also self host. It was kind of an integrated math, data science, research, writing, and teaching platform.

@prologic@twtxt.net It was super useful if you needed to do the sorts of things it did. I’m pretty sad.

At its core was Sage, a computational mathematics system, and their own version of Jupyter notebooks. So, you could do all kinds of different math stuff in a notebook environment and share that with people. But on top of that, there was a chat system, a collaborative editing system, a course management system (so if you were teaching a class using it you could keep track of students, assignments, grades, that sort of thing), and a bunch of other stuff I never used. It all ran in a linux container with python/conda as a base, so you could also drop to a terminal, install stuff in the container, and run X11 applications in the same environment. I never taught a class with it but I used to use it semi-regularly to experiment with ideas.

I hadn’t run it in awhile, and when I checked in with it today I found their web site brags that cocalc is now “extensively integrated with ChatGPT”.

Which means I can’t use it anymore, and frankly anyone doing anything serious shouldn’t use it either. Very disappointing.

Math support in Markdown
Mathematical expressions are key to information sharing amongst engineers, scientists, data scientists, and mathematicians. Today we are pleased to announce that math expressions can be rendered in Markdown on GitHub using $$ as a delimiter for code blocks with math content or the $ delimiter for inline math expressions. ⌘ Read more

being able to render TeX math equations to PNG files is pretty empowering, because it allows me to write about more technical things here that would otherwise be more difficult to communicate in plaintext.

When I read this I see a a niche, super premium hardware company that managed to acquire tens of thousands of customers by word of mouth. Not only that, their customers are all in-effect self employed or small businesses with huge average revenue per employee. They manage global supply chains, intense competition, all while taking on and managing huge legal/compliance risk. How is is that supposedly “dumb,” criminals can do this, and yet many of us are stretching our intellectual capacities to learn new technologies and maths, developing our nth stupid app, trying to achieve a fraction of the customer traction and revenue that street thugs manage to do every day. Are these people much smarter than average, or does it mean that if you sell something people actually want, literally nothing else matters about your intelligence, education, character, background, or anything at all. When I read these drug stories, it just reinforces for me that growth solves everything. You can succeed with a crew of violent, drug addicted idiots whose only reliable characteristic is short term thinking, and who spend half their time in prison if you have product market fit. What I’m beginning to think is that the “smarter,” people are in a company, the less anyone will want their product. It’s like the success of a venture is inversely proportional to the number of ostensible geniuses it employs. reply How Police Secretly Took over a Global Phone Network for Organized Crime | Hacker News
