New to mastodon... just learned about it and it seems like an amazing project.
It'll probably take me a while to get used to the platform 😅

I'm self-educated in tech (networking, programming, security) and have been looking to contribute to some OSS projects for a while. Hoping to contribute to the cause, and to maybe switch from my current career as a digital artist into development full-time

how math is presented: "this knowledge came fully formed out of someone's head at the same pace that you are reading it"

how math is done: "this person became obsessed with a problem, worked on it for anywhere between a week and their entire lifetime, and finally produced a very messy version of this knowledge which was later refined and expanded by other mathematicians"

OK, this is a "boosts needed" post, please boost this if you see it. At least one organisation I'm involved in has a major problem in that it runs online and needs to be able to ballot members, and just about all the easy services for doing so aren't GDPR compliant.

Would anyone be interested in clubbing together to try and run a Euro-side, compliant server of CIVS or a similar e-voting system that could be used by community groups, activist orgs, and so on?

I've got three weeks to find a job before I lose my backup plan to foreclosure, and another month past that before I lose my home. I need gas money to get to job interviews. I'm eating the shipping on these bracelets to try and cover that. If you don't wear #jewelry or these aren't your style, please boost. They're anodized aluminum, brass, bronze, and stainless steel, all 7 inches, and all $15 to paypal.me/tarlimanjoppos or cash.app/$tarlimanjoppos #maille #art #mastoart #chainmail

A long exposure night shot from our few days away in the desert (Prince Albert, Klein Karoo, Western Cape, South Africa). I'd had a loooong-ass day and was suffering from a sinus headache so I couldn't be bothered moving from the stoep of the cottage, and just shot whatever was in frame from that vantage point XD

You can write any program you want, so long as it's in C++ and does nothing more than print a string (we are very lax about what kind of words you put in this string, so long as it follows our string-printing guidelines)

Truly ours, -Big G.

I was about to submit my solutions to Google Code Jam this years, but I realise they don't allow arbitrary languages anymore. Instead, you have to use C++, Python and a few more.

That's absolutely ridiculous, and I have no interest in joining anymore. I think this is an indicator of just how boring and mainstream Google has become.

Don't dare to use a language which is not following the norm. But conform to the lowest common denominator. That's what Google itself has become, boring

PORTMANTDOME: TWO WORDS ENTER, ONE WORD LEAVES

Breaking news in the algorithmic/arithmetic world!

Integer multiplication in time O(n · log n). [1]

It means you can multiply two n-bits integer using roughly n log n operations. It's a *very* important problem because a lot of mathematical software rely on efficient integer multiplication.

It breaks the last best known algorithm [2] (Schönhage–Strassen), that was in O(n · log n · log log n)

@welshpixie sneaky Pixz running off and hiding in a different instance!! I found you though.

Right, your turn. Cover your eyes and count to 100 and I'll run off and hide somewhere on t'internet ;)

Interesting description of a buffer overrun in Chrome: googleprojectzero.blogspot.com

You know what would have prevented this? The use of a memory safe language. Arguing in favour of C or C++ because "it's fast" hasn't been a valid argument for decades.

"How to Think Like a Mathematician"

Or maybe the title should have been 'How to Think'.

Oh I'm so disappointed. I had visions of Inspector Baboon and his plucky trainee Detective Springbok driving around Cape Town solving puzzling crimes using their cunning animal senses.

So I'm researching the proper procedure for giving my #sewing machine a tune-up and it's come to my attention a lot of people are using WD-40 in their machines.

Let me be clear: WD-40 is NOT an acceptable lubricant for anything more critical than a door hinge!

It is a corrosion barrier. It's meant to prevent rust in things like hinges that are exposed to the weather and the like. It does have some ability to lubricate but it is almost never the oil you're looking for.
