Those look to have ~80 CRI. Having used LEDs with 80 CRI and ~93/94 CRI, I can absolutely tell a difference. I would prefer 90+ CRI, but those don't really seem to exist yet.

I just made another post about this, but I have about about 15-16 cree bulbs in my house. I take a picture of the receipt and the packaging at the time of every purchase.
I've had trouble with two--both 40W TW series bulbs. These bulbs flickered--they would turn off and if I adjusted--or even tapped on the bulb--the bulb would come back on for a time. The problem got worse until they barely worked anymore. I thought it was the fixture until I tried one of the bad bulbs in a desk lamp and had the same issue.
Anyway, I emailed Cree tech support with the photo of the receipt and packaging and had 3 new bulbs fedexed to me two days later.
I'm annoyed by the quality lapse (less than a year), but I don't have any problems with their response.
That's what I'm really hopeful for--a dimmable, high-CRI, 100W equivalent LED.
Hmmm, interesting. I've upgraded almost my entire house to Cree bulbs over the last two years. I had one fixture that had three 40W TW (high CRI) bulbs--the only 40W crees I've used--that were all bought at the same time. Two of the bulbs died within a week of each other--they flicker off and if you tap them will turn back on. I'm assuming some solder or some other connection has weakened. I'm going to try to fix them, but that's neither here nor there.
I emailed Cree support with a picture of my receipt and a picture of the original packaging (taken at the time I purchased them). Cree immediately offered to Fedex me three new bulbs (including a replacement for the third bulb) and did not even ask for me to send the old bulbs back. I had new bulbs two days later.
I'm disappointed that the bulbs didn't last that long, but I couldn't ask for any better response out of Cree's support.
Try the Cree TW series bulbs (a few more bucks per bulb, and a few more watts). They're still not perfect, but they're much better.
Besides, a lot of these "managed" environments provide type safety guarantees. Preventing your data from being lost or disclosed due to a defect in a program can be worth more than the marginal cost of a managed environment.

Since when? The US Department of Veterans' Affairs was among the first to adopt an electronic health record system. In the late 1970s, it began to develop the MUMPS-powered VistA system now used by nearly half of all U.S. hospitals with electronic health records. And VistA is free software.

But in the case of rape or murder, well, that will end family ties for a few decades.
For this purpose, would you consider "rape" to include sexual contact between an 18-year-old and a 17-year-old when the 17-year-old has presented fake ID? Or are you in the "save it for marriage to avoid accidental molestation convictions" camp?

Modern pseudo-slavery differs from slavery in the first half of the nineteenth century in one important way: the child of two wage slaves is not a slave to either of his parents' employers.
How about Pledge of Allegiance — is that a "cohesive contract"
Members of some religious groups handle this by not saying the Pledge at all. They pledge allegiance only to god, or they say a parody pledge referencing a pyrotechnic accident in 1984:
I pledge allegiance to the flag,
Michael Jackson makes me gag.
Pepsi-Cola burned him up,
