Among the myriad injustices, I had forgotten this one.

I grew up on land stolen from the Sioux. This hanging wasn’t quite local, but we had our own earlier version we didn’t learn about in history class.

I’ve only put together pieces 50 years after leaving Iowa. The various Sioux peoples had been forced to give up their lands in MN and northern IA, in exchange for payments of food that were both inadequate and frequently late. This was itself an abrogation of the imposed exchange of lands under Jackson’s Indian Removal Act.

@Torvaney @generativist Yes. If you are testing a stochastic system, you need to observe its behavior. But you only get statistical results, with all that implies.

But most stochastic tests I've encountered, it's just the test that's stochastic, not the SUT, and I want to pull out my hair. @Torvaney @generativist You weren't really being that flippant. Choice of what to test, and what you can make easy to test, and where the value lies, is the whole ballgame.

@Torvaney @generativist I'll argue that a property test is just a well-chosen unit test.
My algorithm is intended to not just drive you to write unit tests, but to write *productive* unit tests, and then stop. And write more if you later you didn't hit all the bases.

It needs to be adaptive & strategic @Torvaney @generativist There are a lot of unit tests that should never be written. They are either a waste of time, or they become high maintenance items later.

But the goal is to avoid spending a lot of frustrating and boring time dealing with bugs.

@whatisaidis @UtneTorvald @RedStateBlues_ @kazweida Pat Robertson's Reagent University, and therein lies a tale.

The first thing you need to know is he joined Jews for Jesus, and his first SCOTUS case was Jews for Jesus vs LAX, which got him Robertson's attention and the rest of us "free speech tables" at airports, etc. @whatisaidis @UtneTorvald @RedStateBlues_ @kazweida The second thing to know is he leveraged that into playing a MAJOR role in RW evangelist circles as a litigator for supposed oppression of Christians. Despite his initial SCOTUS victory, he's lost most of his cases there, but won a few important ones.

1/ It all comes down to the economics of adoption. Coal is becoming a stranded asset; banks are not backing coal plants (which coal people see as a conspiracy rather economics). 2/ Cost, siting, price risk (the risk that your investment today will become uneconomical in competition with future, more advanced installations), and scale (which sets the magnitude of the risk), time to ROI, and risk uncertainty.

She's badly confused on units.

She has taken 0.2 W/m²/decade, did the conversion she was demanding of me, to get 6.342e-10 W/m² instead of the correct-but-confusing 6.342e-10 W/m²/s. @TheClimateHawk @DawnTJ90 @StealthFlyBy @d_e_mol @GillesnFio @AltUS_ARC @SConwaySmith @davidyoung13 @SylviaD32911201 @RegimeChangeBC @Austins_coffee @LeeLafferty4 @terrymorse @Captbobdad @BrunoPresents @watt4prez @birdhillll @ChrisBradley133 @craigthomler @ClaireNewton79 @BRodermund @JaggerMickOZ @Mark_A_Lunn @Gladfly1 @FriendsOScience @KStafford67 @brandondaly2018 @caerbannog666 @Mathenaut @haerycammel @BardLackey @andsnz @MadnessVs @sheoaks1 @priscian @CymaticWave @boggywood @HughAbercrombi3 @truthtrumps1 @drwaheeduddin @PAlterBoy1 @MichiganFront @torpet002 @CriticalStress_ @NikolovScience @MamaMac_ @Sci_Resistance @GeorgePembroke @kevpluck The meaning of the latter is how much the W/m² increased per second. Dropping the /s allowed her to cast it as the total integrated over a decade, introducing an error factor of 3.15e8 (a number I did give her—the number of seconds in a decade).

Let's keep it simple: natural gas combustion turbine.

Wind turbines use a TINY fraction of neodymium, or none at all, depending on design. Presenting this mine as representative of the impact of solar panels (which don't use it) is beyond stupid, it's dishonest.

@aria606 @MichaelEMann Well, besides not working everywhere, they are both very slow investments, very large capital costs, and both produce a lot of opposition due to their specific environmental impacts. We can't rely on them to solve the problem,.

But progress on ANY of the fronts gets us closer. @aria606 @MichaelEMann Wind, solar, and batteries are already well established even if they are still in the early stages, because of their economic and deployment advantages. They're where we are making the fastest progress.

But we are also adding hydro globally, for example in China and Canada.

@aria606 @MichaelEMann Storage has been part of the US grid since 1929, with over 25.2 GW installed as of 2018, with more being added all the time. CA has almost 1.2 GW in progress

It is possible to have a grid w/o storage, even with wind/solar, with enough geographic diversity, but it won't be robust @aria606 @MichaelEMann So storage is and always has been critical. (It's not just robustness you sacrifice, but also economics; you have to overbuild).

It is critical that you never over-power the grid. That always means, taking some power out of the grid. You can't easily operate a nuke at low power

Even farmers with an 8th grade education know that's BS (h/t to my late uncle). Every carpentry tape measure has two adjustments to the reading. Notice the hook on the end is loose. It adjusts automatically for hooking over vs butting against.

The other is marked on the body of the measure. The one I was just using reads 3 1/8 inch/79 mm. It is the amount you have to adjust if you measure with the body butting up against something.

@rawphonegirl @BCAppelbaum Hi. Do you understand what that vote was? Let me walk you through it.
First, the bill under consideration was titled H.R.648 - Consolidated Appropriations Act, 2019

It would fund various parts of the government. It passed. Only 10 Republicans voted for it. @rawphonegirl @BCAppelbaum You can read the full roll call on the bill here:

@SVChucko I'll have to see later if I can access the study. A lot just look at present economics, but you really need to look at the installed life, and reasonable projections of future market. Deep solar will change things.

But as it notes, there are other reason for residential. @SVChucko In particular, to reduce fire risk, we're having grid shutdowns. Reducing the impact of those will be important.

On Jan 3, the Dems ought to introduce a bill to strip Trump of nuclear first strike authority, and insist it be signed into law before any discussion of a wall.

It's a matter of national security.

@ToreSays @WildRootsStudio @seansu @attilatheblond @koush @WarWraith @TwitterSafety @RealAlexJones @infowars @jack I fucking DID read it. First, it is the order that carries weight, not the preceding arguments. Nonetheless, let me walk you through them.

After introducing the case on page 2 we find this, much like what I quoted above. @ToreSays @WildRootsStudio @seansu @attilatheblond @koush @WarWraith @TwitterSafety @RealAlexJones @infowars @jack Then it goes on for about 7 pages describing Twitter and blocking, and turns to Trump's account on page 9, and continues for 3 pages. On page 12 it turns to the individual plantiffs and their being blocked. Page 14 it covers the Knight Institute.

1/* Well, I can't actually answer the "why so many", which is at the crux of this, but I can provide some relevant background.

I may have to do this piecemeal. I'll indicate when I get to the end.

But let's start at a beginning. The Bible, translated to English. 2/* In 1526, William Tyndale published the first English translation of the Bible. This was not popular with the oligarchs of the time, and escaping to Holland did not help. He was executed for heresy: strangled, then burned at the stake (I guess it's better in that order!)

1/* I'd have to see if they're actually engaged in learning; learning about the issues, the opponents, the political levers of power, how to communicate and effectively leverage social media.

You think I'm applauding what side they're on. Understandable, but wrong. 2/* Consider Dianne Feinstein. She's even older than I am. Even older than my mother would be. Oldest in the Senate. Been advocating for better gun control her entire career. Knows a thing or two about politics.

1/ Liberalism stems back to John Locke and expanded by Adam Smith. Smith's first book, Theory of Moral Sentiments was published in 1759; Wealth of Nations in 1776. It is the latter work in which he used the phrase 'invisible hand', but read carefully. 2/ Note the word "frequently". He is not making the claim that free markets solve all problems or that they can't create new ones. Notably, he never used the phrase "laissez faire". He understood trade as part of an organic economy, but was not a cheerleader for business.

1/ A few problems here. First, the fact that the kids are cousins had nothing to do with their admittance. That link is not part of the "chain". And calling it "chain" is a deliberate obscuration of "family", so points off for propagandizing. 2/ Married children are the second-lowest priority, F3. So after a 5 year wait to become citizens, another 23, so we're out to 2046 for the next step.
