New Samba Problem

I’ve gotten Samba working on my Fedora server, and I can see and read files on it from my Windows 2000 box, and when I first got it working (I had a firewall problem) I could even write to it. But now when I try to drag files to it, or save them from an application, I’m getting an error that indicates a permission problem. I can’t imagine what it could be, since the files and directories are all write permission for the user, and I’m the user. I can write to them as a user on the Fedora box itself–I just can’t do it from the Window’s client.

Anyone have any ideas what could be the problem, or how to diagnose it?

Tuning Up The World’s Tiniest Violin

The Iraqi insurgents were boo-hooing to Zarquawi last week that their morale is low. Ain’t it a crying shame?

The author of the letter also “admonishes ‘the Sheik’ for abandoning his followers” after last year’s U.S. siege on Falluja, west of Baghdad.

U.S. forces led an assault then on the Sunni Triangle city’s terrorist network believed to be run by al-Zarqawi.

Because of the “continuous pressure by Iraqi and [U.S.-led] coalition forces,” a military statement said, al-Zarqawi has relied on his cell leaders to conduct operations while he is forced to evade being killed or captured.

Doesn’t your heart just go out to them?

A Peek At The Future?

I just got an interesting note from Popular Mechanics:

At 12:01 a.m. EST, Popular Mechanics will unveil on its Web site an early look at Lockheed Martin’s proposed Crew Exploration Vehicle — one of two major proposals submitted today to NASA to replace the Space Shuttle and eventually carry us to Mars. We’ll be including images and specs. A larger piece will run in our June issue.

I don’t know if I’ll stay up for it (I’m still recovering from the Space Access Conference sleep deprivation), but comments here are open for anyone who does. I’ll take a look in the morning. I am curious to see what Lockmart will propose, particularly now that the competition has gotten more heated with the apparent decision to only award a single contract.

[Tuesday morning update]

Here’s the story.

The biggest obvious difference between it and the Boeing concept (at least the Boeing concept that has been on display in the exploration studies–I can’t speak to what was actually proposed) is that it’s got wings. Or at least a body with a lot more lift than a capsule, with supersonic drogues. Despite that, it still lands with chutes and bags, so it’s not clear why they want such a high L/D, except for more cross range and landing site flexibility, and reduced entry gees. What NASA has been calling a Service Module they seem to be calling a Propulsion Stage. It’s not clear whether it also contains life support consumables (as the Apollo Service Module did), though it does mention that the crew module itself has a LOX supply and fuel cells.

It definitely looks more sexy than Boeing’s design–they may be hoping that will help them as it did in X-33, but having that much L/D is a problem for the launch vehicle, because it will impart bending loads (for which it’s not designed) on it from the side force of the lift. It will be interesting to see how they explain this.

Recapping Star Trek

I can’t think of anyone better to do it than Lileks:

“The Next Generation.” The post-Reagan years. The Enterprise was no longer a lone vanguard making its way through realms unknown; now it was like a grand Hilton in space, complete with spa, psychiatric counselor, accommodations for kids, and a French captain who could sometimes be mistaken for a cranky sommelier. Whoopi Goldberg was the ship’s bartender, which, in retrospect, really tells you all you need to know. Patrick Stewart’s Captain Jean-Luc Picard was much-beloved, and for good reason: His stentorian acting style gave the show a dramatic heft it otherwise didn’t always deserve.

The Federation, in this iteration, was like a liberal dream of the U.N.: diplomacy first, multicultural understanding above all, but if need be, a gigantic armada could be summoned to fight off whatever evil leather-clad empire had decided to mess with the goodfolk of Earth. Zeitgeist giveaway: The Klingons became allies, sort of, after the Berlin Wall fell. Grade: B+, not so much for overall quality, but because it relaunched the franchise with a broad-based appeal no subsequent version would match.

Back To Boca

I had a long travel day yesterday. My scheduled return flight was supposed to leave Phoenix at 3:30 in the afternoon and arrive in Fort Lauderdale (via DFW) after midnight. I went to the aircraft in the morning, assuming that I could get an earlier flight to Dallas, and thus get home earlier, on standby.

Wrong.

I ended up spending all the time at Skyharbor not getting on to three separate flights, and ended up taking my original flight anyway. Next time I’ll do more than verify that the flights exist–who would have thought that so many others would be so desperate to get out of Phoenix yesterday?

Michael Mealing has a summary of the results of the panel discussion that ended the conference Saturday night. Thanks again to Henry Vanderbilt (and particularly for getting a hotel with wireless everywhere) for putting on another good get-together for this growing community.

[Update at 10:30 AM EDT]

Clark Lindsey has some good further coverage of the sessions that I didn’t get to, or write about.

Schmoozing

I need to circulate a little, and my tender derriere is killing me from sitting in this conference-room chair. Back later, perhaps to cover Jerry Pournelle’s talk after dinner.

[Update in the early morning, on my way to bed]

OK, so I didn’t work up the head of gumption necessary to blog the last session. It would have been kind of a pain, since I was on the panel to close out the meeting.

More later, after I’ve gotten some sleep, gathered my thoughts, and figured out what happened here this weekend.

Afternoon Session

I’m listening to John Carmack describe future plans for X-Prize Cup and future vehicles and flight tests, but I’m getting sore wrists from blogging in my lap, so I want to conserve keystrokes for Jim Muncy, who is scheduled to speak shortly. I should mention that as a result of switching from peroxide to LOX/methanol as propellants, John says that Armadillo has about fifty thousand dollars worth of good peroxide equipment that he’ll let go cheap. His next vehicle should be a space vehicle, and he expects to crash it a few times in the process of perfecting the design.

3:06 MST: Jim Muncy is coming up to the lectern to speak now. His job as a political consultant is to help space entrepreneurs at the intersection between their endeavors and the political sphere. Talking here primarily about t/Space (among his many other clients). First part of t/Space consortium is AirLaunch (a company of Gary Hudson’s) that has one of the Falcon contracts. The goal is “operationally responsive spacelift.” Joint project between DARPA, Air Force and NASA.

Title of his talk: AirLaunch, t/Space and a Fast Prototyping Path to Prompt Global Strike, Orbital Tourism and Maybe Even the Moon.

Thanking everyone here for getting the regulatory legislation passed last year, for which this conference was a key event.

NASA has decided that working with these crazy people like Scaled Composites and the entrepreneurial space community is a good idea. Goal is to responsively replenish, replace satellites and respond to space threats, a capability which the nation currently doesn’t have. Also able to get several thousand miles in a couple hours and deliver a payload. Key part of program is developing Small Launch Vehicle (hopefully more than one) for smallsats into LEO or hypersonic test vehicles, at less than five million dollars per launch. Trying to return to the launch vehicle paradigm operating in the DC-X program.

Upper stage for launch vehicle isa two-stage self-pressurizing LOX/propane system. Goal is 24-hour response time. It’s launched from a C-17 transport (aircraft can carry two). No aircraft modification required. Benefits of air launch aren’t performance, but safety in ability to abort, and security, provided by the ability to hide launch location until the last minute. Vehicle is deployed by gravity (about a 750-foot drop prior to ignition, with a large right bank by the aircraft to prevent collision).

t/Space has people from both entrepreneurial community and aerospace establishment: David Gump, Gary Hudson, Jim Muncy, Brett Alexander (White House space policy), Jim Voss (veteran NASA astronaut–will run vehicle development). Two key contractors are AirLaunch LLC and Scaled Composites.

A frontier means new resources and opportunities, not just new knowledge. Create the frontier through government leadership, not government ownership. Inviting private sector to party means more affordable and more sustainable.

They promote commercial delivery of crew, cargo and propellant to LEO. Don’t use CEV as a means of getting crew to orbit–turn that over to the private sector, and use CEV in space. Don’t base the hard part of going to the moon on the system that gets people into orbit. Their CEV would be space based, and return to LEO via aerocapture. Transportation between earth and LEO would be done privately. The proposal is a split-level architecture: ETO and LEO to Moon. Goal of architecture is to get to lunar-produced propellant as soon as possible. They send a convoy of two vehicles to the moon for redundancy and safety.

They propose air launching their crew transfer vehicle on a “stilt” 747 carrier aircraft. It has longer gear to allow the vehicle to be slung underneath to carry peoploe into LEO. It uses LOX/Hydrogen. A second air launch concept is a new airplane by Burt (that he wants to build for other reasons), which is a “White Knight on steroids.”

Goal is to help NASA go faster. Hopeful that new program direction of single CEV contractor will free up funds to allow NASA to have “non-traditional” approach in parallel.

Concerned that Air Force will only have enough money for a single Falcon concept to go forward. Would like us to lobby the Hill to get them to make sure there is sufficient funding for two concepts, to keep the competition going, and keep more companies developing low-cost launch vehicles. Talking about ARES (Affordable REsponsive Spacelift). Not encouraged about it, because it’s being managed by traditional missile guys at the Air Force. Wants to get Congress to encourage the Air Force to work with non-traditional players, and get new management in place. If we can’t get an award to go to the small guys, we should at least get the big guys to get the small guys as suppliers for subsystems.

He’s announcing a new activity that could provide the seed of a new NACA for spaceflight, by developing synergism between the Air Force Research Lab and the entrepreneurial community, called ORSTEP (ORS Technology Enterprise Partnership–where ORS is Operational Responsive Spacelift). Hoping for five million in FY 2006 to get it started.
