Awake almost two days. That’s what it takes to beat a relapse the first week. I want to leave Australia. Stagnant energy here. Failed twice.
This is my third shot. Poker taught me variance. Double up and take the shot. If it fails, try again. Play through the downswings. A bad beat is yesterday. Get up and play your best game.

Maximising the value of a portfolio. Using #Variance, CoVariance and Portfolio Variance. Briefly Variance is the deviation of a stock’s return with its own average returns, Co variance on the other hand is the variance of a stock’s return with respect to another stocks’ return. http://financemetrics.scienceontheweb.net/ Using #Matrix Algebra in a 5 Company Model. #economics #econometrics

In case anyone's keeping score, the idea that JFETs have hugely variable properties and that this problem cannot be - or at least has not been - fixed with different design or manufacturing practices, this batch showed it pretty clearly to me.
20 J113s, minus 1 fake, equals 19 devices. I measured the Vgs / pinch-off voltage and the Id / drain current in my test rig. The result?
6 very distinct bins with between 2 and 6 devices in each. Vgs overall varied from (-) 1.30 V to 2.11 V (variance is 38% of the larger value, or 62% of the smaller...), and Id from 5.7 mA to 12.8 mA, a spread of 125% (!) of the smaller value.
No wonder so many JFET circuits just don't work if you don't hand-match the devices.

🤔 Invariance, Covariance, and Contravariance in .NET C# 🤷♂️
➡️ If it is so hard on you to really understand this topic, don’t feel ashamed of it, you are not alone.
➡️ It happened to me and many other developers. I even know experienced developers who are using them but still can’t understand them well enough.
➡️ However, this is the past. In this article, you are going to understand it once and for all.

but I not only have an strain-wide average leg size for the flies, but also a strain-wide #variance. So I can do the same GWAS to find genes associated with the morphological variation within a strain

The second is the number of sequences in the training MSA. The more the merrier, given they are of similar quality. We show that the number of sequences is - perhaps unsurprisingly - connected to the #variance of the inferred statistical model.

Wow, the statistical concept of #variance turned 100 years old this July. That's so young in the mathematical history scale! It's hard for me to imagine statistics without variance.
