Comment Re:Wayland Remote Rendering (Score 1) 300

Late followup to this. It is non officially planned and Kristian is working on it. And if he is working on it, it should arrive by the time Wayland is slated to take over from X.org.

A libwayland application may start up a proxy compositor on the machine (server, appliance, closet PC in your example) and blit the compressed damaged regions over the network. Or an RDP (or SPICE, VNC) server could offer the proxy compositor (even through SSH).

He also has commented on examples of a rolling hash algorithm to instruct the client to reposition damaged regions vs re-blitting their contents.

Now that the 1.0 specification has been released, I hope to see others helping out in the area of remoting. Nobody's going to deny that Wayland can't do everything X11 can do today, but they're also not positioning Wayland to replace X11 _today_.

Comment Wayland Remote Rendering (Score 4, Informative) 300

For everyone bitching about Wayland vs X11 and network transparency, you need to watch this talk by Kristian Høgsberg. Keith and the rest of the devs have always said that remoting would eventually come down the pipeline.

And for everyone else talking about efficiency of sending pixmaps via the network, you should learn how your current stack actually works. It will be much better with Wayland.

I've used X11 since 1995, I'm very fond of it. But I also realize it needs to go...

Comment ES&S IVotronic (Score 5, Informative) 386

The machine in the video is an ES&S IVotronic terminal. It's the same terminal I voted on this morning. It directly appears the digitizer is incorrectly calibrated. What the video author doesn't show is the paper tabulator in the lower left corner. It would of clearly showed his vote being tallied incorrectly. Perhaps he was voting Romney and didn't want his cast vote shown, but the paper trail recorder clearly shows your selection in the window. It even shows when you got back and correct a selection. Now, they key is that each candidate field on the screen is independently calibrated and can be re-calibrated in under a minute by any third party.

At minimum, this terminal should of been isolated and inspected for tampering. Hopefully that was the ultimate outcome. I know I would of not left the area until a proper election official arrived.

Comment Professional Broadcasting (Score 4, Informative) 180

Insightful write up. Getting rare here on ./

For those not RTFA, they are referring to using Ethernet in professional live broadcast situations. Aka, newsroom or outdoor sporting broadcasts where cable bundles are still common. I believe they are imagining a world where a broadcast truck rolls up to a stadium and runs a few pair of 100Gbe fiber vs a large coax bundle. This could save considerable time and money. Some interesting bw numbers:

SD 270 Mbit/s
Interlaced HD 1485 Mbit/s
Progressive HD 2970 Mbit/s

What I really want?

I work on the move all the time and am very rarely in an office. My HTC Thunderbolt on Verizon 4G is one of the key factors that allows me to actually work _and_ get out and enjoy society. I've fielded calls and worked issues sitting in my car in a Target parking lot. But, that's what I do. I basically get paid to be available at a moments notice and provide support. I am happy with the trade off. I get great flexibility, and in return, give up some of my personal freedom.

So, here's my biggest issue to date. Smart devices are getting too big to be truly portable. Try dragging a 4.5" device around the gym on an armband. Or find a place for it on a 5 mile run. I need to be connected, but sometimes only really need the old school phone/texting features. What I would love to see is carriers offer a single phone number that will route to multiple SIMs in multiple devices. That way, when i don't need the power and bulk of the Thunderbolt, I can grab a small and pocketable device instead.

Perhaps Google voice can accommodate this? Anybody have any experience with it?

Comment Re:Navy's answer to Chinese Anti-Carrier Missile (Score 1) 482

Doubtful. Current carrier fleet defenses are pretty impressive (forward to 2:30) already. And the Nimitz class carriers now use RIM-116 point defense systems (a carrier never travels alone).

The laser defense is just the last layer of the strategy and part of the overall big dick swinging contest. The Air Force is working on it, the Army is working on it, and the Navy wants its part.

I could see its use for cooking UAVs and other type stuff where you don't want to be wasting $1M missile shots. It's definitely a more economical weapon (sans development cost). It's also more effective against high trajectory fire, similar to MTHEL's capability.

Comment Choice of F-104 (Score 2, Interesting) 85

The choice of the F-104 is by no accident. It's low altitude performance is well known.

Darryl Greenamyer's Red Baron F-104 did 998 mph (mach 1.30) officially and 1013 mph (mach 1.33) unofficially. At less than 300 ft, back in the '70's. The J79 has to be water/alcohol injected during runs like these, otherwise it will exceed it's maximum inlet operating temps.

Say what you want about the F-104, but it was built to fly straight and fast, intercept and shoot down bombers. Another work or artfrom Kelly Johnson and company IMHO. Especially considering the timeframe.

Too bad the North American Eagle team are having a hard time raising funding. It's interesting to see a J79 powered 104 go up against all this new radical technology. The F-104 was known for it's low altitude speed ability.

I just posted in the wrong thread. Synopsis:

I made a lot of money back in the 90's repairing NTFS installs. The similarity with it, back then, and EXT4 is they are/were young file systems.

Give Ted and company a break. Let him get the damn thing fixed up (I have plenty of faith in Ted). Hell, I even remember losing an EXT3 file system back when it was fresh out of the gate. And I'm sure there's plenty who could say the same for all those you listed, including ZFS.

And your comment about extended data caching. Is your memory short? Remember "laptop mode", specifically setup this way to keep the hard drive from having to spin up...
