NASA requires plutonium-238 for radioisotope power systems for spacecrafts. Plutonium-238 was a by-product of now defunct Cold War–era nuclear weapon factories.

Oak Ridge National Laboratory produced a 50-gram sample in late 2015—the first since 1988. This year, having refined the process, the lab expects 300 grams. They want to ramp up to 1.5 kilograms per year.


I saw this roll through Twitter the other day: a bot that's as good at detecting toxicity as Google is in 50 lines of code

It came from this thread where there are complaints that the Perspective API may not outperform a random number generator.

This would be hilarious if it weren't for the fact that Google is serious about it, and some big media outlets are likely to use it.


"A Tennessee judge has rescinded his controversial program that sought to encourage drug-dependent female and male inmates to cut their jail time by voluntarily agreeing to undergo birth control procedures.

White County General Sessions Court Judge Sam Benningfield of Sparta filed the order on Wednesday, a day before two state lawmakers asked Tennessee Attorney General Herbert Slatery to render a legal opinion on the controversial program's constitutionality."

I've sort of switched...

DuckDuckGo has !bangs. If you search for "!so javascript", then you just end up on stackoverflow.com with a search term of "javascript". There's dozens (hundreds?) of these !bangs -- including !g if you want to run the search on Google.

So I've installed this extension below for Safari. I use the !bangs in the address bar if I want to go somewhere specific -- !so (stackoverflow), !a (amazon), !y (stock quotes). And, otherwise, it just uses Google search.

Interesting.. I do something similar with the Search Engines setting in Chrome using Keywords which applies to what is typed in the omnibox.

a iphone -> searches for iphone on Amazon

w tiger -> searches for tiger on Wikipedia

You can also set up a new search engine/keyword. Example to set up Stack Overflow with the s keyword: https://stackoverflow.com/search?%s

So I can now type 's sort a string in python' and it will take me directly to https://stackoverflow.com/search?q=sort+a+string+in+python


I tend to use the tab complete feature. Works on pretty much every site I ever use search . Just start typing the url and press tab.


Lean hogs.


I believe everyone is referencing the index key size length in MySQL. In that case you can get "ERROR 1071 (42000): Specified key was too long; max key length is xxxx bytes" errors.

This happens even in InnoDB -- it's taking the maximum byte size of all the key fields. For a single VARCHAR(255) in MySQL utf8 that ends up being 3*255=765 for just that one field. If you add other fields, it's really easy to hit the max key length and have the create or alter fail.


See my reply to parent on why the max must be calculated (no false positives on duplicate key in edge case).

The default row format changes in 5.7, so key size is max is now much larger.


I used to know IBM'ers who said it stood for "I Be Moving"


Awesome sauce
