The assassination thing gets tried now and then, but assassinated leaders have a habit of being replaced by other leaders, who are not always better. Sometimes, instead, they're replaced by multiple would-be leaders and a civil war, also not necessarily better.
I wrote that it was "before Detroit caved itself in" via unions.
Which was the fucking point. Unions had nothing to do with Detroit's demise no matter what Koch's teabaggers tell you.
I'm not anti-union.
Prove it. Point to a pro-union comment by you made before now.
Go to the link in my sig, look for "Grandpa Got Dismembered By A Shambler"
think of the children!
they're the ones who'll be forced to watch the slideshows.
and eventually suffer the indignity of having "cute" baby photos of them brought out to embarass them if they're ever dumb enough to bring a gf or bf home.
that photo archive isn't an innocent collection of memories, it's malicious forward-planning by parents.
good post, except for three details:
1. if you're using ZFS on both systems, you're *much* better off using 'zfs send' and 'zfs recv' than rsync.
do the initial full copy, and from then you can just send the incremental snapshot differences from then on.
one advantage of zfs send over rsync is that rsync has to check each file for changes (either file timestamp or block checksum or both) every time you rsync a filesystem or directory tree. With and incremental 'zfs send', it only sends the incremental difference between the last snapshot sent and the current snapshot.
you've also got the full zfs snapshot history on the remote copy as well as on the local copy.
(and, like rsync, you can still run the copy over ssh so that the transfer is encrypted over the network)
2. your price estimates seem very expensive. with just a little smart shopping, it wouldn't be hard to do what you're suggesting for less than half your estimate.
3. if you've got a choice between hardware raid and ZFS then choose ZFS. Even if you've already spent the money on an expensive hardware raid controller, just use it as JBOD and let ZFS handle the raid function.
> Just don't let ZFS know that there's more than 1 drive.
That is *precisely* the wrong thing to do. As in, the exact opposite of how you should do it.
Instead, configure the RAID card to be JBOD and let ZFS handle the multiple-drive redundancy (raidz and/or mirroring), as well as the error detection and correction.
Otherwise, there is little or no benefit in using ZFS. ZFS can't correct many problems if it doesn't have direct control over the individual disks, and RAID simply can't do the things that ZFS can do.
Of course, this means that you're actually better off with a cheap dumb non-raid HBA card (or even just the SATA ports on your motherboard if there's enough of them) than an expensive HW RAID card. This is another advantage of ZFS.
(a good option is to use an LSI SAS2008 card or similar, and make sure it's re-flashed to "IT" mode firmware if you're using consumer-grade SATA drives with it to avoid TLER issues. readily available brand new for under $100 for 8 SAS/SATA ports)
> You can't have them both trying to manage the redundant storage.
yes. and it's ZFS that should be managing it, not the raid card.
> ZFS certainly isn't necessary though, if you've got hardware raid.
wrong. RAID does not provide error detection or correction. RAID protects against drive failures only, not silent corruption.
true, but you do need multiple disks (mirrored or raidz) to protect against drive failure.
two or more copies of your data on the one disk won't help at all if that disk dies.
fortunately, zfs can give you both raid-like multiple disk storage (mirroring and/or raidz) as well as errror detection and correction.
That ZFS_data_integrity link in the post you were replying to gives a pretty good summary of how it works.
The paragraphs immediately above that (titled 'Data integrity', 'Error rates in hard disks', and 'Silent data corruption') also give a good summary of why error-correcting filesystems like ZFS (and btrfs) are necessary, especially with the huge sizes of modern drives.
In fact, anyone interested should read the entire wikipedia article.
ps: neither raid nor ZFS is a substitute for backups. you still need backups of your data (preferably with off-site copies) to protect against accidental deletion or overwrite (snapshots can help with this if used intelligently prior to the event) or burglary or catastrophic damage like fire or flood.
" I explicitly mentioned that if your ROM isn't actually RO"
NO ROM is RO, excepting burn-once optical discs. Unless you laser-lock the pins after programming, there's always a method for programming the silicon.
"you can in fact read but are just choosing to misinterpret in order to pleasure yourself."
No, you just don't understand what you're talking about. 25+ years of doing this, here.
No, they're rated R. Now, if Fritz the Cat (the only feature length cartoon to ever get an X rating from the MPAA) were a Xmas movie...
It looked legit but was an obvious spoof.
You need more coffee. Monsanto is a chemical company, not an electronics company. Why would a chemical company spread printed circuit boards?
I'm surprised you never heard of polychlorinated biphenyls (which I probably misspelled), they were used as transformer oil for almost a hundred years (that's electrical transformers, PCBs were used as coolant). My dad was a lineman, he's now dying of cancer from PCBs. Purina killed his dad, Monsanto is kiling him. Yet dufuses at slashdot scream for less regulation. Meanwhile, now that we have the EPA you can drive past the plant in Sauget and the air no longer burns your lungs.
You've proven me wrong -- I used to think there were no stupid questions. This is not 1940s technology, dimwit! That's like if slashdot had an article about a self-driving corn harvester (they may actually have them, I don't know) and you say "What's this doing on slashdot? We've had tractors since 1920!"
Technology is technology, engineering is engineering, whether automotive or IT.
If you don't want to read the story then don't click the damned link, dumbass. Nobody held a gun to your head.
Indeed. Why am I discriminated against because I'm single? Why does a widow with a child pay more in taxes than a childless married couple with the same income? IMO, there should be no marriage deduction, and marital status should not come into play with any law.
Isn't that entire business model predicated on the idea of "trying" rather than "succeeding"? As soon as you succeed, you're basically out of a job, right?
Who cares if you're out of work if nobody's poor and you don't NEED to work?? The problem is you're thinking in terms of "business models" because when the only tool you know of is a hammer... capitalism and markets will be obsolete in a post-scarcity world.
Agreed -- it took me four years to write Nobots, because I had to work every day to pay the rent and eat. I may finish my newest, Mars, Ho! this year, along with getting The Paxil Diaries (which took longer to write than Nobots) in print, because I retire in February.
