okay, so let's say I use tar or cpio, how do I get file attributes I set via chattr? I just double-checked the man page for GNU tar, and for cpio and didn't see a way to do it.
I'd very seriously like to know, because to my knowledge there's currently no way to backup an ext2 filesystem, at all. dd isn't an answer either, restoring via dd requires identical (or mostly identical) hardware, something which isn't always available when you're restoring data off of a 5 year old machine.
It's fine to kill a program, if there is a replacement but tar, cpio and dd aren't replacements.
A fundamental question. Does this release of 2.4 make it so that dump is now reliable, or is dump deprecated as a method of backup forever?
If it's the latter, can any of you linux gurus tell me what is the current "accepted" solution for making backups. Not archives or images, backups.
For those of you who are going to say dump works fine on 2.4, please read this message from Linus Torvalds. I keep hoping he'll change his mind though, at least until a viable alternative arises.
Actually, data validation for web applications should generally occur at all levels.
Client-side javascript, because it's fast, friendly, easy, and generates no load on your server while being nice to the user.
In your PHP/JSP/whatever pages, to make sure what the user is sending you is legit, after all there could be a bug in the javascript or they could turn it off or not have it supported.
In your database itself. If usernames are supposed to be stored lower case, put a CHECK(user == LOWER(user)) or whatever. If a column is required do you make sure it's NOT NULL, or do you rely on your middleware? constraints in the database are a good thing.
This method not only gives you quite a bit of redundancy in your data validation, but it also scales nicely so when you decide to change languages or to use an alternate language to play with the database for some application, you're not risking creating a state that's invalid for another application.
Laptops like this one are nice too. A decent laptop with some anti-corrosion features, and most importantly, a transflective display, so you can use it on deck as well as below.
I want to thank everybody for helping out the troll reply drive. 17 responses in a half hour, truly, this has been one of the most sucessful drives ever.
I'd like to thank all of you who've contributed, with a stylish tote bag, and a brand new Sarcasm Detector.
I know exactly the story you're talking about, and it wasn't the New York Times, it wasn't FrontPage, and he didn't get arrested. I tried to find the real details, so I could cite the source, but slashdot's search engine didn't cooperate.
Actually my first thought was that this was to make it so you can't fence the cell phones and resell them. After all, a thief wouldn't have any particular reason to care if they were using somebody else's phone number.
If you want your government representative to take you seriously next time there's a privacy invading proposal, then please, please do not write, call, fax or email them about this. Save your outrage for laws that cause actual harm.
And then never mind overreacting for no apparent reason on slashdot.
This advertising technique only works if the phones are cool. If the phones don't have new features to show off, or they don't work well, all you've done is convince somebody that they don't want to upgrade from their current phone.
Perhaps I'm missing something, but what's the problem with spending $5 million on the roll-out of a new luxury product? What's next, outrage that TiVo often gives free units to stars, in the hopes that they'll like it enough that they'll end up saying TiVo during interviews?
Here's a shocking revelation. Not everybody is like you. I've gone into the source of mozilla to find knobs to twiddle, to add my own knobs, and yes, even to fix a bug.
Just because you don't use the source doesn't mean nobody does. The world has millions upon millions of people who know who to program, nearly all of whom can look at mozilla's source and tell you what it's doing.
They are using regenerative braking. That's what the whole article is about, a new application of regenerative braking in a place that people don't usually associate with relatively new technologies.
I understand the political motivation for this attack, but this is just irresponsible.
Where will I find information on new artists? Where will I download popular music? Where will I look up lyrics to that song that's stuck in my head?
Whoever did this may have made a point, but they've hurt us all in doing so, as both listeners and artists no longer have access to the vast array of valuable services provided by that fine organization.
Maybe I'm missing something fundamental here, but it looks like what you've created isn't really a hash table, but an array with a poorly designed external index indicating which portions of the array contain data.
Additionally, it would seem to me that obtaining the Nth element of this "hash" would be an O(N) operation, which provides, let me calcuate.... yes, zero gain over using a standard array.
The only real advantage I see is a short-term increase in job security due to the likelihood that people will look at that and say 'What the fuck is he doing this for?' and thinking you're far more clever than you are.
Maybe I'm off-base here, but I wouldn't want to know what was going on. I know that boys drive like idiots on purpose, girls drive like idiots by accident, and both of them occasionally use the cars for puroposes other than transportation.
Any parent who gets one of these really needs to reevaluate their relationship with their kid, and their parenting techniques.
My exact words were that you should attempt to make a switch to PNG. If such a switch is not practical for your content, then clearly this isn't a good option. Nowhere did I suggest that you should induce suffering or death upon yourself over some JPEG-related patents.
Whining is a bad thing, because habitual complaints put the attention of the complainers, not the problem itself. 1,000 posts noting the state of the patent system, corporate greed and a lack of ethics in modern society will not get us royalty-free jpegs, end microsoft's desktop monopoly, cause the RIAA to support P2P, cause the MPAA to support transferable digital video content, allow musicians to get paid, prevent violations of the GPL or give you a way to overclock your Celeron 300 to be faster than a daul Athlon MP 2100+.
On the other hand, discussions about possible solutions for each issue, methods to educate the public about the problem and methods to enact action at a local level can make a difference. Perhaps somebody here works for a corporation of sufficient size and influence to get proper PNG support in the next version of IE. Perhaps somebody here has been thinking about implementing support for another graphics format in mozilla, and might be driven to take that step.
It's impossible to know what could be accomplished if slashdot attempted to direct the energy it spends mindlessly whining at analyzing the problems the community has identified, and analyzing possible solutions.
Whining on slashdot is masturbation, it may be fun but it doesn't change anything. Pretending otherwise is as unrealistic as my hope that this post may inspire a rational discussion as to what the realistic remedies to this situation are, and what the full impact of this situation really is.
After all, perhaps somebody could talk to these folks and get them to license the patent for free to open source software, thus garnering good will, and they could then just milk the PhotoShops and such of the world.
Of course that's just my opinion, I could be wrong.
That sentence embodies much of what's wrong with "the slashdot mentality". If you really don't like this patent bullshit, you should attempt to make a switch to PNG. If you merely say "this sucks", then continue to eat the tripe you're being fed, you've succeeded only in whining.
And the solution to removing the power from military regimes in the Middle East is to buy a bicycle. Sorry, but that just doesn't fly. The goal is to keep the things you like, not to change your life because somebody wants some boneheaded laws.
You not only know how much you paid for a watch you bought in 1986, but you also wear a digital watch all the time? Go take a shower, go out and get laid. It's clear that your wife isn't doing it right.
It's also illegal to modify ATM machines to give you money without deducting an appropriate amount from your bank account. The nerve of the government, always keeping the thieves^Wpeople down!
or the system could do something novel, like print the users vote on a piece of paper which the voter can see through a window until they confirm their vote, then into a bin it drops. then if Jenna Bush claims she didn't win the 2028 election, there's a machine-generated easy-to-audit pile of paper, in addition to the electronic methods of auditing.
this system is about as trustworthy as dating advice from slashdot.

And what does Linus say I should do in order to preserve file attributes at the filesystem level (those set with chattr).
I'd very seriously like to know, because to my knowledge there's currently no way to backup an ext2 filesystem, at all. dd isn't an answer either, restoring via dd requires identical (or mostly identical) hardware, something which isn't always available when you're restoring data off of a 5 year old machine.

fwiw, I'm well aware that there was not one logical statement in the parent message. I'm just a bad person.
These people are buying T1s for hundreds of dollars a month, then selling us a lousy 3Mbps for $80/mo. That's a rediculous amount of profit!
We need to contact our government representatives, and do something to prevent this sort of gouging now, before it's too late.

Actually, I use mozilla on freebsd, but I still don't think it's appropriate to purposefully crash people's web browsers. Grow up.
nice link, jackass. FYI, moderators, the link is designed to crash IE.
