The HP is only 208 nits of brightness. 300 nits is considered by many to be the absolute minimum for being outside. The Mac is probably 500 nits.

I agree, it is one of the great joys of parenting :) I think it helps a lot with imagination, curiosity, and "fastidiousness about truth" since they need to keep evaluating whether what you tell them is true. A deeper variant of t

IMHO PG's best essay since thinking for yourself is a complex topic that underlies many of his previous essays yet is explained so well here. A few things stuck out to me that could have deeper explanations: I suspect conformity has ju

TiDB is for larger scale data and thus a better comparison would probably be with AWS Aurora. We do see customers saving money by taking on the complexity of operating a database themselves rather than using the AWS offering.

The issue is that a PCR test does not actually tell us if a virus particle is live or inactive. A shed virus particle can still have intact RNA for the region tested by PCR. There are published case reports where someone has tested PCR posi

This study says live virus has only been confirmed to be seen for at most 9 days. However, (presumably inactive) virus particles can be shed for months afterwards and can show up as PCR positive. This meta analysis only includes studies of

There seems to be some common ground (even if soil is in dispute!) on high yield dilution though. The abstract states: Contemporaneous analyses of modern versus old crop varieties grown side-by-side, and archived samples, show lower mineral

How long until pay off? I spent a week on their previous model and then returned it and am now happily using an earlier version of the Kinesis Freestyle Edge.

The other important number that is manipulated is inflation (CPI). When you add the manipulation of inflation and joblessness together along with encouraging financial asset bubbles you can pretend to have a great economy when there is actu

That assumes the effect in the study is real and that there is no increase in mortality or ICU admission: unfortunately stopping the trial early casts doubt on that.

Nobody is dying. The only endpoint that improved was recovery days.

Strong evidence for a benefit is often measured by death or something extremely severe. When using other clinical endpoints cherry-picking is to be avoided. [1] > For a trial to stop early for benefit, the observed effect on the composit

The study you links to uses death or heart failure as an endpoint. If there had been lower mortality or ICU admission halting the trial early would make sense. With the only improvement being quicker recovery the value proposition of the tr

At this point to my knowledge there is only one treatment that have been shown in an RCT trial to have a large effect: that is giving bolus dosages of vitamin D. [1] The effect was that only 1 (2%) of 50 patients needed ICU admission wherea

The original Remdesivir trial by the drug company was a high quality RCT (randomized control trial) - except that they stopped it early once they saw a statistically significant positive effect (even though the effect was somewhat underwhel

Thanks, I was thinking the same thing. Marconi deserves credit for developing the concept of radio as we know it for long range communication whereas Tesla invented radio and demonstrated remote control but did not pursue communication. ht

After reading this article I take away the opposite conclusion: with controlled burning these communities could dramatically reduce their risk. What would be helpful is a law requiring controlled burning for human habitation.

Yes, it is a form of 2PC that happens transparently during normal transactions. It is designed to perform well for production workloads whereas Vitess now has 2PC but warns against using it and requires configuration changes to enable it.

Hi, I work at PingCAP and can try to explain the difference between the two options. TiFlash (fast column-based storage) was important in this story and an equivalent doesn't exist for Vitess. Vitess is a MySQL sharding system. In this
