Magnesium Combustion System Design Log 

@ACTupper Sounds exciting! You have thought about injecting the magnesium molten? 650° is a nice friendly melting point, unlike most of magnesium's other characteristics. Unwanted oxide deposits won't melt (under practically attainable conditions anyway) but do clean off with vinegar if not overheated.

When Théodore Géricault painted The Derby at Epsom in 1821, that's genuinely how people thought horses looked when galloping.

It wasn't until 1878 that photography proved otherwise.

But people didn't like the "correct" way; it looked wrong to them...

@chadloder You are suggesting that Elon Musk bought Twitter to altruistically boost the profits of Starbucks and Amazon?

Here's the fix. They pulled two signals horizontally out of the "Group Decode ROM". They went to a NOR gate and an inverter that they added in an empty space. This signal went to another NOR gate, the gate split in two to add another input. This strange layout caught my eye.

@kenshirriff Easy mistake to make. Interrupt handling is tricky.

@smari Can be hard to outsource things you'd write in an evening; glad you made it work.

@shriramk @VirginiaEubanks @epicprivacy Perhaps you are correct; I will have to consider it. Thank you.

I am a qualified disagree. There's a time and place to call out all the great services, protocols and software in the fediverse. That time and place are not the first 5 minutes someone has heard of the network. If people say "Mastodon", just say "Mastodon". And then help them along as the learn more.

@shriramk @VirginiaEubanks @epicprivacy What I said above is slightly wrong: I should clarify that disproportionately placing surveillance cameras in Black neighborhoods is an example of how greater efficiency can make algorithmic law enforcement more harmful than human law enforcement even without secrecy; secrecy is a separate issue.

@shriramk @VirginiaEubanks @epicprivacy I'm criticizing the *title* of the article, and the way it uses the word "algorithms".

I agree that we should criticize harmful ways of using algorithms, of which there are of course many. But the things you're describing are a question of lack of transparency in government, not of use of algorithms. Keeping secret files on citizens on paper, or conducting secret hearings, would also be harmful, for the same reasons. Secret algorithms can be more harmful because they are more efficient, of course, and more extreme. The article's example of placing automated traffic cameras disproportionately in Black communities is an example of how this can produce injustice: heavily policing Black neighborhoods has been a known problem for decades, but automated cameras remove the cost, potentially enabling far deeper levels of oppression.

However, the article consistently uses the term "algorithm" in a way I am sure you will agree is nonsense:

'The nonprofit spent 14 months investigating the city’s use of algorithms and found they were used across 20 agencies, with more than a third deployed in policing or criminal justice. ... The project team concluded that the city is likely using still more algorithms that they were not able to uncover.'

If we interpret the term 'algorithm' according to its standard meaning, these sentences make no sense, because are so trivially, obviously true (except for the part about "more than a third"), but yet are presented as if they are news, the damning results of a 14-month investigation!

This is like the political candidate who accused his opponent of having a sister who was a known thespian and having himself matriculated in his youth. It's utterly indefensible, shameful scaremongering, and it leads to the kind of travesty mentioned at the end of the article:

'Last month, lawmakers in Pennsylvania...proposed an algorithm registry law.'

In less law-abiding places than the US, expect mob violence instead.

I haven't read EPIC's report, and so I don't know if this is entirely Wired's fault.

Here is another video tour of the moon, featuring hi-res images of several areas of the moon, including the Apollo landing sites imaged at resolutions as high as 25 centimeters per pixel.

The tour also highlights the mineral composition of the Aristarchus plateau, evidence for surface water ice in certain spots near the south pole, and the mapping of gravity in and around the Orientale basin.

Mistodon: this is a highly characteristic specimen of piquANSI's #AsemicWriting, enshrined into #asciiart box-drawing characters. This piece was included in our MIST1118 artpack collection released four years ago this month.

Not a surprise, but still disappointing. Canada makes copyright term extension official. Term extended to life + 70 years as of December 30th.
New works entering the public domain lost for a generation.

@VirginiaEubanks @epicprivacy @shriramk Nor am I accusing you of *being* either ignorant or shameful. I am saying that the people who will do the lynching are ignorant, and that the *act* of whipping them up like that is shameful.
