A Potential Breakthrough?

A new class of high-temperature superconductors:

According to Steven Kivelson, a theoretical physicist at Stanford, “[there exist] enough similarities that it’s a good working hypothesis that they’re parts of the same thing.” However, not everyone hopes the mechanism is the same. Philip Anderson, a Nobel Laureate and theoretical physicist at Princeton, says that an entirely new mechanism of superconductivity would be far more important than if they mimicked the current understanding of superconductivity. “If it’s really a new mechanism, God knows where it will go,” says Anderson.

Let’s hope.

Bring On The Meat Factories

Hey, I’m all in favor of factory-manufactured meat, if it can be made to taste as good as the naturally grown variety, but I’m not going to stop eating meat until it happens. My criteria are basically intelligence based, and the first animal I’d give up eating, if I were going to give up any,s would be pigs, but I still occasionally have pork. I don’t feel that badly about eating cattle–they just don’t seem that bright to me. And the question of whether or not they’re better off living a short life, and then being slaughtered, than never having existed at all is one that, as noted, is purely subjective and unresolvable in any ultimate sense. I know that I’ve seen some pretty happy looking cows on the hillsides overlooking the Pacific in northern California. I can think of worse lives.

By the way, Phil should be aware that marsupials are mammals. The distinction is placental versus non-placental mammals. And there are people (probably some of those “bitter,” out-of-work folks) in this country who eat possum, and armadillo.

I Know What He Means

Lileks:

The Piccadilly was knocked down for the Marriott Marquis, which is really one hell of a hotel. I stayed there for a week; loved the rooms and the hotel and the location, but I absolutely hated the glass elevators. Practically had to huff a bag of laughing gas to get on the things.

It’s a problem with Marriotts in general. The large atrium with the glass ‘vators seems to be a trademark. I hate them. They don’t seem to take into account the acrophobes among us.

Fedora Upgrade Woes

OK, so I followed Pete’s advice, and tried an upgrade from Core 7 to Core 8 via yum (yes, I know that Core 9 will be out shortly, but I figure it would probably be a mistake to go directly from 7 to 9, based on previous experience). Everything went fine until the end, when it failed with this message:

–> Processing Conflict: glibc-common conflicts glibc < 2.7 Error: No Package Matching glibc.i686 So, now what? [Evening update] OK, I ended up having to completely blow away glibc. Unsurprisingly, it broke my installation, with no obvious way to fix it. But it allowed me (finally) to do an ftp upgrade via a rescue CD. I'm now running FC8.

Reinventing The Wheel

Thomas James has a question that I’ve often wondered about as well:

I have to wonder, has every project I have ever worked on with LM (X-33, VentureStar, ET, CEV/Orion, among others) started from scratch with everything from numbering schemes to release processes to configuration management to data vaulting to drawing formats and standards to basic skill mix and team structures? You’d think that after so many decades that a lot of this stuff would have become routine by now — revised periodically as new technology becomes available, of course, but not built anew every time.

A counter argument to this — and one I used frequently when confronted with the All-Encompassing Michoud Excuse for Not Improving Processes: “That’s the way ET does it” — is that one ought to take advantage of the start of a new program to incorporate the lessons learned from other programs, thereby continuously improving the way business is done. Unfortunately, there doesn’t seem to be a middle ground between status quo and Year Zero when it comes to these things.

Every time we used to do a proposal at Rockwell/Boeing, and have to describe the systems engineering process, it seemed like we had to come with a new process flow description and graphic, as though we’d never done this before, instead of taking an existing one and tweaking it, and this applied all across the board–in risk mitigation and management, trade analyses, etc.

If I were running one of these multi-billion dollar corporations, I’d put someone in charge of boilerplate and legacy, so that there was a one-stop shop of best practices and material for use in both proposing and managing programs. Maybe they have one, and I was always unaware of it, but if that’s the case, that’s a big problem as well.
