Linux Gets Dynamic Firewalls In Fedora 15 176

Posted by Soulskill
from the changing-on-the-fly dept.
darthcamaro writes "Linux users have long relied on iptables for in-distro firewall setup. The upcoming Fedora 15 release changes that and introduces us to new dynamic firewall technology. 'Most Linux systems use IP tables type firewalls and the problem is that if you want to make a change to the firewall, it's hard to modify on the fly without reloading the entire firewall,' Fedora Project Leader Jared Smith said. 'Fedora 15 is really the first mainstream operating system to have a dynamic firewall where you can add or change rules and keep the firewall up and responding while you're making changes.'"

However according to Hommey, these new faster and less sluggish builds of Firefox for Linux will be available only from Firefox 6 onwards and we expect the first beta of Firefox 6 to available only by September - October 2011.

So, Firefox 1.0 came out in Fall 2004, and only in Fall 2011 will the Linux version be as fast as the Windows version?

Only more evidence that Linux on the desktop is still a toy for masochistic nerds.

So, don't buy music if you don't like the terms under which it is sold. It's their product, and if they want to sell it under onerous conditions and make their customers "gamble", that's their right. If you don't like it, don't buy their music.

Not liking the terms under which a product is sold does not entitle you to pirate it. A return policy is not a civil right.

What, you saw a bunch of iMacs? Those are the computers - that slab of aluminum is all there is. There's nothing hidden under the counter.

The only computer Apple makes that they could conceivably hide is the Mac Mini, and there's no reason to - it's about the size of four CD jewel cases. It's small enough that you might be excused for not noticing it - but no Apple Stores hide them.

Why is this getting so much press? The maker of an expensive, cheesy robot dinosaur toy files for bankruptcy. What a shocker. This should be a 1-paragraph blurb tucked in some back corner of the Wall Street Journal, but instead I've been seeing it on every website I check for nearly a week.

On another note - who in their right mind would pay $300 for this thing? Who in their right mind would think someone would pay $300 for this thing?

The Guardian Shifts To Twitter After 188 Years of Ink 211

Posted by Soulskill
from the save-the-trees dept.
teflon_king writes with news that renowned British newspaper The Guardian will be abandoning its paper-and-ink distribution scheme and publishing all articles and news as Tweets. Quoting: "A mammoth project is also under way to rewrite the whole of the newspaper's archive, stretching back to 1821, in the form of tweets. Major stories already completed include '1832 Reform Act gives voting rights to one in five adult males yay!!!;' 'OMG Hitler invades Poland, allies declare war see tinyurl.com/b5x6e for more;' and 'JFK assassin8d @ Dallas, def. heard second gunshot from grassy knoll WTF?' Sceptics have expressed concerns that 140 characters may be insufficient to capture the full breadth of meaningful human activity, but social media experts say the spread of Twitter encourages brevity, and that it ought to be possible to convey the gist of any message in a tweet. For example, Martin Luther King's legendary 1963 speech on the steps of the Lincoln memorial appears in the Guardian's Twitterised archive as 'I have a dream that my four little children will one day live in a nation where they will not be judged by the colour of their skin but by,' eliminating the waffle and bluster of the original."

Sorry, but you're quite wrong here. Most filesystems can be configured at mount-time to behave in the manner you describe, but by default, they may defer writes to the disk for upwards of several seconds.

This improves performance tremendously, and the resulting unreliability is simply a tradeoff that is required to deal with what are fundamentally very slow devices.

You do not want the filesystem to striving to dump all data to disk as fast as possible, all the time - for instance, it doesn't really matter if you lose some items from your browser cache during a crash. So, the filesystem can defer writing new files in your cache until the disk is idle in between some more important operations, and the only effect you'll notice is vastly improved performance.

That's not a problem, that's a feature. What, you want a window manager or something? Most people don't want to worry about process management on their freaking phone.

If a developer wants to build an application that remembers where the user was when it last closed and returns to that spot when it launches again, that's certainly doable on the iPhone.

A Mac is a genuine Unix workstation that is much easier to administer, and has much better software and hardware support than Linux.

I can run basically every Linux/Unix application on my Mac, both command-line and GUI, while not having to worry about wireless networking drivers, printer support, power management / sleep support on my laptop, getting accelerated 3D drivers working, or any of the other minor hassles that are involved with setting up and maintaining a Linux install.

If you walk into the computer science department at MIT, basically all the faculty have a Mac, and fully half the students do. These people are not buying Macs because they saw a cool ad on the bus - they're buying them because a Mac is the best tool available.

The argument that Macs are just expensive, "designer" PCs that look pretty and sell well because Apple has marketed them well doesn't hold water. Yes, they have nice hardware, and a clean, polished, slick UI, and that does make them more pleasant to work with than some blob of Dell plastic running Vista - but they have the functionality to back up their appearance, as well.

Yeah, they're more expensive. If you value your time at all, you should realize that spending an extra $100 on a Mac is well worth it if it improves your productivity. Hell, if you ever spend two hours fighting with some weird issue on your Linux box, it's no longer saved you any money. You know how long I've spent fighting with the OS to get my wireless working, or hibernate working, or whatever, in Mac OS X, in the five years I've been using a Mac? Zero. I'm not exaggerating. It lives up to the hype. It "just works". It gets out of my way and lets me get things done.

The first version always gets thrown away.
