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.

What Are They, Chopped Liver?

Apparently Aerojet is getting into the responsive reusable engine business (albeit with Air Force funding). I think that’s great, but I have to wonder if the reporter has been paying attention to what has been going on in the industry:

The last US-designed and produced hydrocarbon engine was the Rocketdyne RS-27, based on 1960s technology and now out of production.

There may be some qualifying adjectives that would make that statement true (of thrust greater than X? Used in an orbital launch system?), but folks like XCOR and Armadillo, and Masten, and several contenders for the LLC would be surprised to learn that they haven’t been designing and producing hydrocarbon engines for the past few years.

The Dog That Didn’t Bark

The Rocket Racing League is going to make a press announcement on Monday, but the release raises some questions:

Rocket Racing League Composites Corp. will announce the acquisition of a leading aircraft manufacturer and a partnership with a leading engine manufacturer…

…WHO:
Granger Whitelaw, CEO, Rocket Racing League
Peter Diamandis, Co-Founder, Rocket Racing League
Adam Smith, Vice President, EAA
Len Fox, Test Pilot, Rocket Racing Composites Corp.
Scott Baker, President, Velocity Aircraft
Neil Milburn, Armadillo Aerospace
John Carmack, Armadillo Aerospace

We have a missing player, and a new player. XCOR was building the initial racers, but they don’t seem to be represented at the event. And this is the first time that I’ve heard Armadillo associated with the project. So apparently, for whatever reason, Armadillo is now providing propulsion for the racers, and they’re apparently acquiring an aircraft manufacturer (Velocity?). I wonder why they have to acquire Velocity. Can’t they just buy modified aircraft? Or maybe they’re being imprecise in language, and it’s also a partner?

This obviously raises many questions, none of which I know the answers to, but it would seem to be bad news (though of course by no means fatal) for XCOR. It certainly won’t affect their work on the Lynx. It’s also good news for Armadillo, and it means a new customer with apparent confidence in their hardware, even after the engine problems at the cup last October.

Perhaps the questions will be answered at the press conference, if asked.

[Update a few minutes later]

Actually, on reconsideration, it’s not even obvious that it is bad news for XCOR (though clearly John Carmack must think that it’s good for Armadillo, or he wouldn’t have done the deal). It could be that, now that they’re trying to focus on developing a true suborbital vehicle, the RRL work was proving to be a distraction for them that they’ve now gotten out from under. But it’s speculation on my part, either way.

What Fresh Hell Is This?

ATK is making noises about commercializing Ares 1. Unsurprisingly, it’s full of bovine excrement right off the bat:

Ron Dittemore, president of ATK Launch Systems, said the human-rating that led NASA to build the Ares I first stage around the shuttle booster should also be attractive to other customers with “high-value” payloads, including the Defense Dept. and the National Reconnaissance Office (NRO).

“Ares I can deliver humans, can deliver payload to low Earth orbit; it can deliver payload to geosynchronous Earth orbit and beyond – planetary missions – it’s got that much capability,” Dittemore said at the 24th National Space Symposium here. “And what’s unique is that since we’re designing this vehicle with human reliability, proven demonstrated systems, high-value payload customers may see a real attractiveness to putting either DOD or NRO payloads on this launch system.”

First of all, the Shuttle booster is not “human rated.” The Shuttle itself is not, and never has been, human-rated (I’ve said it before, and I’ll say it again: I wish that we could expunge the phrase “human rating” from our vocabulary–very few phrases in the space business are as misunderstood and misused by so many as this one). What he means is that the fact that they have been willing to use the SRB for the Shuttle (despite the fact that in the case of Challenger, it destroyed the vehicle and killed the crew) led them to decide that it was reliable enough to use for Ares.

One of the things that people don’t understand about “human rating” is that it is not (just) about reliability, which is the probability of mission success. Human rating is about safety, which is a different thing. It is about the ability to know when the mission is about to go sour, and the ability to safely get away from the vehicle before it does. So while reliability is nice, what’s much more important is warning time and escapability, from the launch pad all the way to orbit (something that the Shuttle has never had, which is why it’s not human rated).

But satellites aren’t going to have a launch escape system, so they don’t care about human rating. What they care about is reliability, and I have seen zero evidence that Ares is going to be more reliable than either Delta IV or Atlas V. Human rating the latter two vehicles will not involve making them more reliable–it will involve putting in the systems needed for adequate failure onset detection (FOSD) and ensuring that they have adequate performance to eliminate abort blackout zones throughout their trajectory (something much more difficult for the Delta than the Atlas, due to to its underpowered second stage). So from a mission assurance standpoint, Ares has nothing to offer to a satellite owner over the current commercial vehicles.

Moreover, there is no discussion of cost. Even if they can get away with not having to amortize development, because the government paid for it and it’s sunk, how much of an army will a NASA-developed/operated vehicle require? History would indicate a pretty large one, particularly given the politics of the situation. So will a commercial launch have to pay its share of the annual fixed operating costs, or will ATK (unfairly) be able to subsidize and undercut the ULA by only paying marginal costs for the launch, and having NASA pay the freight for the rest? And it will have to use the VAB for processing, and the NASA pad for launch. Will NASA be reimbursed for the use of its facilities? How much?

This seems like a huge potential bucket of worms, and all because NASA decided that it had to develop its own launch vehicle.

Is ATK serious? I doubt it. I suspect that this is just a PR move to maintain political support for it among the rubes inside the Beltway who don’t understand these issues, to show that it has applications beyond the NASA lunar (and ISS) missions. Unfortunately, it may work.

[Update a couple minutes later]

Oh, and how could I forget this? How thrilled will the satellite owners be to put their bird on the paint mixer that is the Ares 1, on top of that five-segment solid, when they can get a smooth ride on a Delta or Atlas?

“Jews Who Support Obama…”

“…are like poultry supporting Colonel Sanders.”

I think that he really has done us a favor with this new “dialogue” on race. He’s shown how mainstream bigotry is within the black community. As the commenters point out, it’s (finally, and justly) tearing the Democrat Party apart.

And Roger Simon has more thoughts on the “evil” that those Hollywood Jews have done to blacks:

Lee seems genuinely to espouse the belief that African-Americans should only reconcile with Jews if Jews apologize for the supposed evil stereotypes they created of blacks via, I assume, the movies. I wonder if Lee means that Jew Stanley Kramer who made Guess Who’s Coming to Dinner and The Defiant Ones. Or that Jew Ed Zwick who directed Glory? Maybe he’s talking about me for scripting Richard Pryor’s Bustin’ Loose? It’s not the greatest film in the world (though it did win an Image Award that year from the NAACP), but if I was trucking in black stereotypes, I’d like to know. Richard might have too, if he were with us. Or what Jew does Lee really mean? I’d like to see him name names. I’ll name one – The Protocols of the Elders of Zion. Lee is reading from that old racist playback. He is a racist himself.

No, no, no! Blacks can’t be racist. Didn’t you get the memo, Roger?

[Update in the afternoon]

Obama says that no one has spoken out against anti-semitism more than he has. Jake Tapper isn’t impressed:

Really? No one?

Elie Wiesel? Simon Wiesenthal? Alan Dershowitz?

No one?

Wow.

Neither am I. Though, as some point out in comments there, you have to be impressed with his arrogance and self righteousness.
