Is LTO Tape On Its Way Out?

jra Re:The magnitude of Tape:HDD difference is shrinki (274 comments)

I'm not sure I buy this argument; it seems to me to be based on too narrow a view of the universe of different use cases.

I certainly haven't seen *all* of them myself, but in general, I've seen enough to be skeptical of "tape can't do it arguments.

And LTO-10 is 48TB/cart. Uncompressed, I assume.

Is LTO Tape On Its Way Out?

jra Re:its all about selling Autoloaders (274 comments)

LTO-9 goes to 25TB/cart, LTO-10 goes to 48TB.

Already announced.

And wouldn't it be interesting to know if that study was based on cartridge count or capacity?

Of *course* the cart count is going down, not *everyone's* data storage needs expand without bounds, and newer larger sizes imply some catch-up.

Is LTO Tape On Its Way Out?

jra Shyeah, right. (274 comments)

Magtape is the only viable medium for things which are actually "backups" as that term is understood in the professional IT arena. Every other possible medium for backups has faults which cripple it for one or more of the requirements which backups are required to fulfill -- primarily that's length of storage, but there are lot of other fun failure modes.

Sure, spinning magnetic storage, optical media, and flash drives each have some advantages for specific purposes.

But go pull the post-close EOY General Journal from 1996 off of one, I dare you.

And if you think that's an overly strict requirement, a) you're probably wrong, and b) I can come up with lots more that you won't.

My commercial backup guidelines are these:

You need it backed up on at least 4 pieces of media, of at least 3 different types, in at least 2 different cities, in at least 1 different state; bumping each of those numbers up by 1 is not unreasonable.

Only one backup can be on optical media; only one can be on spinning magnetic media, whether it's powered or not (this includes the cloud, and local external HDD backups, whether powered 24/7, alternating, or pulled and shelved).

Flash media is right out, as are SSDs.

I can pull 20 year old DC3000 tapes off my shelf and read them -- as long as I have a SCSI interface for the computer in question.

GNU tar is great that way.

Is the Porsche Carrera GT Too Dangerous?

jra Sounds like it's just like... (961 comments)

...every other 911 derivative for the last 50 years.

The original 911 would just swing that engine right around in front if you'd let it.

When did they become mid-engine?

(Oh: I see: *the 980* was mid.)

Windows Blue: Microsoft's Plan To Release a New Version of Windows Every Year

jra Well... (712 comments)

this is going to be as stupid as Mozilla's plan to rev a new major release of Firefox every 6 weeks.

It's easy to look at this and say "what a great idea"... but the people who do that are, nearly unanimously in my experience, people who are only responsible for 1 or 2 PC.

When you're responsible for 100 or 500 or 20,000, you come back to me and tell me how many more IT people that's going to require you to hir... oh, wait.

No; this is a *great* idea!!!

Nokia Engineer Shows How To Pirate Windows 8 Metro Apps, Bypass In-app Purchases

jra No, it's not. (268 comments)

> It's easy to blame Microsoft for this, but isn't this really an issue that is intrinsic to all installed applications?

No one read John Carmack's "don't let the client control anything" screed several years back, about how gaming systems cannot let the client code *know* or *control* things, because then it could be replaced with something that would cheat on the user's behalf, by looking around corners for bad guys and such?

This is the same exact thing, as far as I can see...

Ask Slashdot: Self-Hosted Gmail Alternatives?

jra Maybe not Zimbra (554 comments)

I've run Zimbra for 3 years now, back to 5.0.9, which I installed for my then employer. The architectural people there have taken, right along, an attitude that I can characterize only as "RFCs? Who cares about those?"

It doesn't handle fixed-pitch well; its editor won't re-wrap (though they might have finally fixed that in 7), it doesn't uknow from RFC 2369 -- in fact, it handles mailing lists poorly in general; notably, you can't change the Reply-To in any way when replying, if you generally want HTML off (as I do), the only way to turn it on is to dive into the Preferences and switch it, then reload; same turning off...

Check for bugs filed on their bugzilla by jra@baylink.com if you want a full list of the ignominy. But in general, I would say: evaluate it pretty thoroughly to see if you can deal with its crap before deploying.

It's *very* pretty. I just don't know if it's worth the trouble.

When Patents Attack — the NPR Version

jra I was a touch surprised that (87 comments)

in all their "Mafia protection racket" analogies, they didn't use the phrase "You gotta really nice lookin' business here", which nearly always precedes "It'd be a shame if something happened to it".

Nice piece, though, over all.

When Software Offends

jra FWIW (467 comments)

I don't have a problem with a developer deciding to use names like this for a package, if they want to stick their neck out.

The point here, is apparently that *the developer* wasn't sticking their neck out; someone else did it *for them*. *That*, I have a problem with.

So, y'all people shooting at the name itself? That's a strawman; please look at what's actually offensive here.

Ask Slashdot: How To Safely Saw Up Motherboards?

jra Fiberglas (247 comments)

Or things even worse. You can do this, but you're going to need pretty hefty realtime dust collection; I suppose it's possible that a Rainbow water-curtain vac might be enough, but I'm not sure.

I'll bet someone else will be sure. :-)

And I'm not sure if you can finish off the cut edge of a board to a point where it won't unravel -- or at least, how you would do so.

People *do* do this: I have a favorite notebook whose covers are circuit boards. But it's non-trivial.

CmdrTaco at Kennedy Space Center

jra Press Site (105 comments)

I was there, for the STS-132 Tweetup, and it is absolutely incredible.

Nearly 2700 press were badged for this launch; the record was 2707 for STS-1, and they might find they've beaten it when all is said and done.

Shame the press paid no attention to the 100 or so in the middle; perhaps the public would have raised more fuss with its legislators about NASA's miserable budget.

The Future of Time: UTC and the Leap Second

jra Aw, jeezus (235 comments)

This has been *progressing*?

This is possibly the stupidest idea in history. Their stated goal: taking complexity out of time handling code -- *cannot happen*: it will *still* have to account for all the years we did this.

And it will break *lots* of stuff.

The Enterprise Is Wrong, Not Mozilla

jra Ars proved that it didn't know what it was talking (599 comments)

about when it said that the 3.0 Linux kernel release was "merely Linus' preference"; it wasn't. While the code didn't rev, the *kernel release practice did*, and it justified the new version number, even to me--and I'm the one who codified traditional version numbering practice in the Wikipedia article of the same name. It's stuck for 2 years now, so I assume I interpreted it properly. :-)

That said, Ars is wrong here, and so's Mozilla: I *was* IT guy, and had 500 seats to deal with, and they'd be pissing me right off if I was still in that position. I can think of no better way to chase medium to enterprise businesses away than to say "we don't give a fuck about you and your problems"... and that market is probably 30-40% of their marketshare.

Owel; someone will tell them "Oh yeah? Well, fork you!", and the problem will go away.

What's good for inventorying IPs, users, and such?

jra jra writes  |  more than 5 years ago

jra (5600) writes "Once every month or so, people ask about backups, network management, and the like, but one topic I don't see come up too often is network inventory management — machines, serial numbers, license keys, user assignments, IP addresses and the like. Anyone care to share their firsthand experiences with this topic, and what tools they use (or built) to deal with it? I'm using RT (because I'm not a good enough web coder to replace it, not because I especially like it — sorry, Jesse) and Nagios 3; I've looked at Asset Tracker, but it seems too much to me like a toolkit for building things to do the job, and I don't want my ticket tracking users to have to be hackers (having to specify a URL for an asset is too hackish for my crew). But IP address space management, DNS zone file building, firewall rules file management, and that sort of thing are starting to get out of hand in my facility as we approach 100 workstations and 40 servers, and I'm looking for something to automate it. I'd prefer something standalone, so I don't have to dump RT or Nagios, but if something sufficiently good looking comes by, I'd consider it. My *least* favorite implementation language is Java, as it's the one I understand least, and I'd like to be able to hack a bit here and there, if I must. Perl and Python are probably up top, along with C. Any suggestions?"

Apollo Anniversary missing its surest voice

jra jra writes  |  more than 5 years ago

jra writes "Apparently, the Passover Effect doesn't apply to 40th anniversaries. CBS News, among other outlets, is reporting the death of Walter Cronkite, renowned for, among other things, anchoring all but 3 hours of the moon landing, tonight at age 92. Cronkite had been ill for some time."

Has NASA found the tapes?

jra jra writes  |  more than 4 years ago

jra writes "For over 5 years, various people both inside and retired from NASA have been engaged in a quest. They were looking for the long-lost original slow-scan video tapes from the Apollo 11 moon landing, which went missing in a record-keeping snafu, covered in unreasonable detail in a Wired article a couple years ago. Well now, according to the UKs Sunday Express newspaper, some tapes may or may not have been found which may or may not be the Apollo video. Apparently — I love the British press — the NASA boffins are a bit put out that it leaked; they were hoping to blow everyone's minds with the scoop themselves. All I can say, though, is Holy Living Fuck."
