sin^3(x)/(1+a-a cos(x))^2 dx from 0 to pi

@level98 Thanks, I might try that. I was just pasting them into wolfram integrator but for some reason it didn't want to do that one.

@level98 I will use a pen and paper, which is apparently a more powerful tool than a laptop.

@level98 Interesting, well at least it appears to solve. I'll try myself at some point. The context looks like this:

(I had my laptop in a conference but didn't swap it for paper, although it seems I should have)

Nobody makes butter dishes which are specific to west coast sticks. They're all either designed without even realizing west coast sticks exists, or they're slightly larger than east coast sticks and you can kind of cram west coast sticks into it with a lot of wasted space on the ends.

@foo In England butter is more brick-shaped. I was surprised by the square cross-section when I saw American ones.

Back to this game with the astonishingly bad deer AI. It actually spawned two stacked on top of each other. What are the odds of that in a map of several acres?

The search trees for Sudoku puzzles. Easy/medium are a straight line of forced moves. Expert level has lots of branches. The hardest known one has a huge number of branches (I wasn't able to plot them all).

There's a certain excitement about doing 8 boring things in a day, because that's 8 fewer boring things I have to do later on.

Proposed new jargon: “toothbrush botnet” to mean “unfounded public panic about an information security threat derived from incompetent journalism about hypothetical scenarios”

Example usage: “it turns out juice jacking was just a toothbrush botnet”

@glyph Usually it's believable because something similar was true.

For instance there was a DDoS attack by assorted IoT devices: https://www.engadget.com/2016-10-28-that-time-your-smart-toaster-broke-the-internet.html

The funniest thing about this whole Gemini debacle is that there's no possible way this could have been a "mistake" or a "rogue employee". People knew they were releasing this.

And that creates a really tough situation for Google management because they know it's an adult daycare, their investors know it's an adult daycare, and thanks to this little fuckup, it's becoming more and more ridiculous for anyone to even play-act that it's anything other than an adult daycare.

Tech investors aren't stupid, they watched Musk take an absolute pig of a platform and cut the team by 90% while still keeping it running. The calls between activist investors and Google management must be exceedingly tense.

@lain @cjd @harblinger The Gemini thing is staggeringly stupid, but Google's search is getting worse too. So perhaps generalised corporate rot has set in?

Things are so much easier to remember when you organise them spatially (have an area for a given task, or put things to go out next near the door).

Computers and the internet kind of ruined this by making everything available everywhere. It actually helps to have FEWER choices but relevant ones.

@lamp @coolboymew The cooker in my rental was kind of like that when I arrived, two of elements were shoved in at random angle and not making contact

sjb,
@sjb@mstdn.io avatar

@coolboymew @lamp It turns out under the "hood" of the cooker, the plug for those spiral elements was just held in by a flimsy metal clip. Someone had tried to force an element in and broken the clip so the plug was lying around in some random place.
