I believe the Amazon link gives the author a few more shekels, but he makes the most money from the first link; details from his website's page on this book.
This publication obtained a copy of the paper Tito et al. plan to present at the conference, discussing a crewed free-return Mars mission that would fly by Mars, but not go into orbit around the planet or land on it. This 501-day mission would launch in January 2018, using a modified SpaceX Dragon spacecraft launched on a Falcon Heavy rocket. According to the paper, existing environmental control and life support system (ECLSS) technologies would allow such a spacecraft to support two people for the mission, although in Spartan condition. âoeCrew comfort is limited to survival needs only. For example, sponge baths are acceptable, with no need for showers,â the paper states.
The IEEE Aerospace Conference is in March -- next month. That's pretty interesting timing.
I respectfully disagree. I've been to four LISA conferences (sysadmin conference run by USENIX) since 2006, and I see very little that is comparable; there are the various LOPSA conferences (LOPSA-EAST, Cascadia IT Conference), but they're simply not at LISA's scale. Want to hang out with a thousand other sysadmins? Get training from Ted T'so on recovering borked disks? See what Google is up to -- or the small IT shop at the university down the coast with 1/20000th the budget? There's simply nothing else out there that matches it.
As for the rest of the conferences, all I know is the summaries I've read in;login: and the material that I've watched/listened to on their website. (And btw, HUGE kudos to USENIX to opening access to their proceedings, talks and papers.) But at the very least, they make damned interesting reading, and have made me very curious about things that are going on outside my narrow focus.
I don't have the breadth of experience you do; I concentrate on system administration because I love it, and I've been doing it less than ten years. I'm definitely an interested amateur (at best) when it comes to topics like security, or file systems, or OS design. But I'm always surprised how much of USENIX conference material touches on areas of interest or direct relevance to me, and at the very least browsing their papers is a wonderful introduction to some research and work I'd miss otherwise. I'm sure (with the exception of LISA) there are more focused conferences, or better known ones (DefCon is one that springs to mind). But I can't agree that USENIX is "past its sell date".
(And in passing, thanks very kindly for all the work you've done for the Open Source/Free Software community. Kinda boggles my mind that I'm debating you...)
I wasn't around then, but I've been reading up on him and all the rest of the Apollo astronauts since. I'm filled with wonder every time I think about it.
Thank you for everything, sir. I hope your eternity is a pleasant one.
What's their methodology? How exactly did they get this info? I see nothing here like a link to a full paper.
Who are they and why should I trust them? Disclaimer: I could turn out to be woefully ignorant, and maybe I should just get my head out of my ass. But their main web page appears to be amazingly content-free, and there are two posts on the blog -- this is one of them. (To be fair, the
They only present two data points here -- Jan 18 and Jan 19. What's happened since? Why the breathless summary (Slashdot's and the blog post) saying file sharing is all going to Europe now?
The post-Jan 19 diagram says the hosting provider breakdown changed, which is presumably why they're breathless about Europe. But there's no data presented on where those new providers are located -- no corporate info, no datacentre locations, nothing.
I think that what you want is The Ephemerizer, by Radia Perlman (she of OSPF fame). I heard about this a few years ago at the LISA conference, and a bit of digging turned it up. From the abstract:
This paper is about how to keep data for a finite time, and then make it unrecoverable after that. It is difficult to ensure that data is completely destroyed. To be available before expiration it is desirable to create backup copies. Then absolute deletion becomes difficult, because even after explicitly deleting it, copies might remain on backup media, or in swap space, or be forensically recoverable. The obvious solution is to store the data encrypted, and then delete the key after expiration.
Keep a list of passwords (I use Emacs + GPG, but there's bound to be something out there that'll work for you if that's not your style)
Print out the list monthly (if that really is how often you change passwords)
Seal it and put it in a safety deposit box at your local bank
Tell everyone "In case of my death, go here for passwords"
(Alternately, this could be something a lawyer could help with -- something like holding passwords in trust, only to be given up in the event of X, Y, Z...)
Yes, it's a pain in the ass. But it would work, and it would mean your executor/spouse/etc would only have one set of people to convince that you're dead.
I'm a Canadian sysadmin. I love -- LOVE -- the LISA conference (http://www.usenix.org/lisa11/). It's wonderful, informative, and fun; I've made great friends there, learned an incredible amount and generally enjoyed myself enormously.
Last year was the third time I went. The conference was in San Jose. I took a bus and a train -- which took over 24 hours -- from Vancouver to San Jose, rather than fly and go through a naked body scanner. I figured if I'm going to talk the talk, I should walk the walk.
I'd already decided to skip this year's conference; it's in Boston, which is a long way to go by train or bus. I didn't want to be away from my family for that long. But I had been thinking about going next year, when it's going to be in San Diego.
I'm not going now. Not if this crap keeps up. I'll watch the video on my workstation, I'll listen to the MP3s on the bus, and I'll stay here in Canada. We have problems of our own -- but random searches and "papers, please" for the crime of taking the goddamned train are not one of them.
I've enjoyed Slashdot immensely for many years now, and it's still the first page I load every morning at home and every slacking moment at work. Thanks so much for all the work you've put in and the enjoyment you've given me, and the best of luck in all you do.
Still, I can't help but think: digital rights management, sure! Where are my rights, as a consumer, and who is managing them?"
And that is why the Free Software Foundation insists on calling this technology "Digital Restrictions Management (http://www.defectivebydesign.org/what_is_drm): it points out that this is meant to keep YOU, the paying customer, from doing useful things with the stuff you buy.
Yep; where I work (small university dep't) one of the faculty members has it on all his desktops.
My main grumble about OpenSuSE is that, at least until 11.2 -- I'm still fuzzy on the details -- you couldn't actually do an upgrade from SuSE itself using zypper; you had to boot from the DVD and upgrade. I'm used to CentOS and Debian where this sort of thing isn't a mix of hope and prayer or a feature request.
I was at LISA '09, and Dr. Bruno Michel (works for IBM, mentioned in the article) made a presentation on this work (or at least very, very similar work). You can see the presentation, or download the MP3, here:
Up here in Canada, we've got a new copyright bill coming down the pike. It's been spearheaded by two Cabinet ministers, Tony Clement (Industry) and James Moore (Canadian Heritage). While Clement has been sensitive and seems open to suggestions, Moore has definitely taken a more combative approach.
In fact, in a recent speech, Moore decried copyright "radical extremists" with a "babyish" attitude toward copyright.
Of course, Xensource/Citrix has already driven away most of the community that would have done this kind of pre-product development, so I'm not holding my breath
I'm curious (genuinely curious, not being snarky)...I've had a bad experience with Xen too, but I haven't kept up with what Xensource/Citrix have been doing. Why do you say they've driven away the community?
Hah! You beat me to it; I was going to say that the reason for the "knee-jerk reaction" is that private companies aren't allowed to put you in jail. So yeah, you'll have to forgive me if I'm paranoid about my government -- the one to whom I've entrusted a monopoly of the use of force -- misusing the 80 craptons of data it can collect on me.
Man, this deliberate missing of the point just irritates me.
There's also this entertaining reading, entitled "THE DAY MY ARSE DIED". Weird thing is, the guy looks just like me when I had a beard, and I ate a phall many, many years ago. It brought back some painful memories.:-)
Try posting this on the LOPSA mailing list. It's an excellent resource, with lots of sysadmins in different environments hanging out. If you're not a member, email me (aardvark atsign saintaardvarkthecarpeted dot com) if you'd like me to post to the list on your behalf. You might also want to try the IRC channel #lopsa on Freenode.
Membership is only $50/year, and access to the mailing list alone is worth every penny. I'm a member, and it's saved my butt on occasion. Even if you're not a sysadmin, this is definitely a sysadmin-type question, and I think you'd benefit from being able to ask questions on the list.
Couldn't agree more. A tape library (as in autochanger) might be out of your budget, but a simple tape drive wouldn't be too much -- say $5000 for an LTO4. Media is $50-$100 or so depending on where you shop. Seriously, you're not going to find a reasonable way of storing that much data anywhere else.
BTW, if you're not a member of LOPSA, you may want to seriously consider it. Even if you're not a sysadmin, this is definitely a sysadmin-type question, and their mailing lists are second to none. It's an excellent resource.

Yeah, they got the link wrong...not sure what happened there.

Well put. Fare well, Mr. Armstrong.
If there's something to see here, I'm missing it.

This was always one of the first changes I made in a new Ubuntu install. Evolution was awful, slow, and I hated it.

I was commenting on a feature like that being so late in showing up...but yeah, fair point.
