No. The helium is used to pressurize the liquid oxygen tank and provide back pressure to the engines. Basically it's the gas that's used to shove the LOX down the fuel lines to the engines as fast as possible.

Also when you're listening to the com loop when you hear "Engine chilldown has begun, they're pumping through the engine.

The prior mishap was caused by one of the struts that holds these tanks to the inner walls failing.
This failure was caused by the tank itself bursting.

I'm suspecting they're going to have to reengineer the COPV helium tanks to be a bit tougher.

Comment Re:Competition....from Oracle? (Score 1) 156

Think about the fact that Intel currently runs entire batches of CPUs customized for Amazon EC2. Yeah, for some small scale cluster Oracle's got some blisteringly fast cluster with kick ass interconnects and fast storage. However unless they're ready to invest the billions Amazon has already invested in AWS/EC2, they'll never be able to compete with amazon at scale.

Also, no matter what oracle does it's still trapped in Amazon's paradigm. Whatever they make for a cluster still has to adhere to amazon's standards so customers can migrate their data over...

Oracle may have built a one off super car, but it still has to drive on amazon roads... Good luck!

My thoughts exactly. I would have been more shocked if they'd said "After 6 months barely any porn use!" I can't understand how this got into the deployment stage without someone with a clue going "You know, we're just putting porn kiosks out everywhere."

Comment Here's what they could do. (Score 1) 618

As a group categorically refuse to train their replacements. If one person says they're going to do it, the administration can single that person out and make an example out of them. When the entire staff locks arms and says "no". What can they do then?

1. Proceed with firing them... That's great except for the problem where all the knowledge goes out the doors.
2. Lock them out... Except they only manage the physical access, so they're not sysadmins, nor know how to close accounts, etc.
3. Lawyer up and sue them for breach of contract or terms of employment?

I suspect the last option would likely be what they'd do, but if that happened what then? If my companies suing me for refusing to train my replacement, I don't see any incentive to train my replacement.

The whole thing seems like a fluster cluck from top to bottom.

Comment Re:Still higher than a Soyuz launch (Score 2) 121

One of the reasons that SpaceX had to go on the K street offensive is because ULA specifically managed to score a 36 launch billet that was a no-bid contract worth billions. This was one of the reasons that SpaceX sued the federal government. It was to force them to open up and competitively bid. As an citizen, do you want to pay 100M a launch of 400M a launch? I'd argue it's the other way around. ULA has a long and storied history (with executives going to jail, etc) of paying to play with congressmen, etc.

Comment Do it right. (Score 1) 366

To echo what I've seen quickly, RAID is not backups. If something (like cryptolocker) suddenly encrypts all your files... you're still completely utterly FUCKED.
If your domicile burns to the group, you're fucked. You need something that'll keep your data consistent, and keep it safe from theft/fire/destruction.

I'm going to ignore any cost considerations... whatever.

Build two identical boxes. The first box is going to sit in your place of residence, the second is going to sit elsewhere (like your parents house, or a buddies)
Each box is running your OS dejour that naively supports ZFS, a pair of 4TB drives, setup as a ZFS mirror volume. Use whatever software you use to copy data to the local box, rsync, crashplan, whatever, once that task is completed, you'll drop a snapshot of all the pertinent file systems you care about. You now, remotely drop a snapshot on our offsite box and then kick off an rsync that catch any changes.

1. If something has drastically gone wrong with your data locally, you can always revert (in this case promote) your latest snapshot (or whatever snapshot you like best). Plus you can thumb through all your snapshots and see what you like...

2. Even if something hasn't gone wrong, but you liked an old version of something, you have that too... though you'll have to decide on a strategy for how many snapshots you're willing to keep. zfs snapshots are now scm but sometimes you realize you don't have something under control and then you wish you did.

3. You've got a full duplicate of this elsewhere in case fire/flood/theft/etc.

4. Monthly do scrubs of your file system just to make sure everything is healthy. Want to expand your volume? Add two more disks and you can tack on another mirror. Yeah, it won't be balanced but you'll suddenly have more space.

Comment Example of something working? (Score 1) 252

Is there a SINGLE instance where a company that was given one of these government contracts actually delivered what was asked for and it wasn't a screeching shitshow?!? Maybe it's simply that the failures are all that get reported and there are companies doing a bang up job without any fanfare...

As much as the MCT will be what gets us to Mars, just as likely it will be because NASA will be hobbled by bureaucracy, bad tools and lack of vision.

Comment Pi with an SO-DIMM Slot? SATA connectors? GigE? (Score 3, Interesting) 134

Thank you for creating a such an awesome and useful little computer.

I've used Pi's to do everything from automatically watering my xmas tree to teaching a fourth grade class basic electronics to doing remote backups of my data (with a pi in my house and one far away at my buddies.)

That last operation suffers greatly from the lack of ram resources on a raspberry pi. My "pi" in the sky remote backup node has an SO-DIMM slot on the back I could stick a 8 or 16GB so-dimm in. 1-4 SATA ports so I write faster and a gigE ethernet interface.

I understand that you're under financial pressures to keep the cost down, but I see a real market for a Pi 3+.

Also, follow slashdotters... if there's a platform out there that accomplishes this that's not a proprietary NAS let me know. I've also investigated several microST motherboards but I don't want to have to deal with a "real" power supply, etc.

I'm still not convinced this isn't some sort of odd false flag operation.

Imagine you're the NSA and you've been unable to get inside of some other countries likely air gapped cyber security operation... putting some juicy tools out there they're likely to snatch up and play with at least get you to see who the players are and maybe these tools work maybe they blow up... As for the vulnerabilities, with so many people playing this game, any vulnerability not found by the NSA is likely to be found by some other organization.

Even the vulnerabilities could be snares... I'm suspect of all of this and think it's just part of a big ruse.

Comment Re:Driving yes, but charging? (Score 1) 990

I owned a Volt for two years and Monday through Friday I drive to and from work 31 miles each way. I have a charger at my house and one at work. During the week, I don't use a drop of gas. I also live in New England where the temperature's this week have been in the high 90's, but in February we went a week where at the average temp was -10 with a low of -22. I've seen zero degradation of my battery life.

Now on the weekends I drive the car out of the range of the battery and need to use gas. For my needs and that of my family it's a great car.

As for hydrogen... Most hydrogen generation starts with a fossil fuel.
