A "Never Reboot" Service For Linux

metalhed77 Re:Ugh, just reboot (321 comments)

Agreed, I track the CentOS and Ubuntu security lists to know when to reboot my services, and chances vulnerabilities for various libraries are much more common than other stuff. That said, a lot of the time you can get away with just restarting a service or two.

I'd put this service in the category of things that'd be nice to have, I'd consider paying $4/mo for it. Of course, if you really 'need' this service what you probably actually need is a hot spare with automatic failover.

Restructured Ruby on Rails 3.0 Hits Beta

metalhed77 Re:Standard Slashdot Ruby comment form (197 comments)

Eeesh, what a tragedy. I got the same BS at my job, luckily my higher up was fired and I replaced him, letting me turn our crapload of PHP into Rails.

I took a good long look at the PHP MVC world when it was clear my company wasn't going to drink the Rails kool aid, and I have to say, none of the PHP frameworks were (at the time, 2 years ago) up to snuff compared to Rails. They were just flat out missing a lot of the features that made Rails great.

Plus, it takes me way less time to code in Ruby than PHP, PHP just takes more LoC, especially as your app's complexity increases.

Restructured Ruby on Rails 3.0 Hits Beta

metalhed77 Re:Standard Slashdot Ruby comment form (197 comments)

Hey, I agree, I wrote that post as a joke, almost all the negatives are easily dis-proven falsehoods. The knee-jerk zealots on Slashdot are too arrogant to educate themselves about this language unfortunately.

7. The ruby community is full of over-hyping zelous twits

You know, I wrote my post as a joke, to hopefully prevent stupid comments like yours. That yours was modded (twice) up is proof of the juvenile partisanship present here on slashdot.

Restructured Ruby on Rails 3.0 Hits Beta

metalhed77 Re:Standard Slashdot Ruby comment form (197 comments)

Well, if you want good, cheap rails hosting you could easily do Dreamhost or Heroku. I'd go with Heroku, they'll scale up pretty well.

metalhed77 Standard Slashdot Ruby comment form (197 comments)

Please pick form the list below

Ruby and/or Rails sucks because:
    1. It doesn't scale (Twitter)
    2. It's slow
    3. I read somewhere that Python was a better language
    4. I write PHP, I can do everything Ruby/Rails can do better
    5. My obnoxious younger coworker uses it
    6. It's not lightweight enough
    7. The ruby community is full of over-hyping zelous twits
Ruby and/or Rails is awesome because:
    1. It scales within reason (Twitter, Lighthouse, Shopify)
    2. It's as fast as Python and PHP
    3. I read somewhere it was better than Python
    4. I used to write PHP, Ruby's been a godsend
    5. There are so many motivated and innovative people in the community
    6. It's featureful
    7. Pythonistas are over-hyping jealous twits

Ruby In Practice

metalhed77 The plural of anecdote (104 comments)

That doesn't really carry much weight. In fact, from what I've seen, those that have migrated to Ruby from Python have largely migrated back - viewing Ruby as an interesting experiment

The plural of anecdote is not data.

While I don't have direct experience, Jython is very mature. ... I suspect, Jython is as mature as JRuby.

Wow, I'd love to hear your opinion about things you have no experience with and have strong suspicious about.

How do you expect to be seriously talking about stuff you claim to not really know about?

I suspect you could benefit by taking a step back, re-reading your post, and spending some time reflecting on your own biases.

Nvidia's RealityServer 3.0 Demonstrated

metalhed77 Ohhh, that's what it's for (91 comments)

I, like many of you here was wondering what the hell this could possibly be useful for, up until I viewed the video.

The answer, clearly, is porn.

It all makes sense now!

Best Backup Server Option For University TV Station

metalhed77 Re:rdiff-backup: like rsync with versioning (272 comments)

I love rdiff backup but I'd never use it on any large datasets. I attempted to use it on ~ 600 GB of data once with about 20GB of additions every month and it ran dog slow. As in taking 6+ hours to run every day (there were a lot of small files, dunno if that was the killer).

For larger datasets, like what the poster has, I'd go with a more comprehensive backup system, like bacula. I use that to backup about 12TB and it's rock solid and fast. There's a bit of a learning curve, but the documentation is very good.

If Bacula is too intimidating rsnapshot would be a viable route, it's similar to rdiff-backup, but simpler (pretty much just rsync + cp using hard links), faster, and easier to use. It's not as space efficient, but diffing video data is probably a waste of time anyway.

Microsoft Poland Photoshops Black Guy To White One

metalhed77 Re:Just like MSNBC: changing black people to white (964 comments)

I'm pretty sure I saw the clip you were talking about. There were 2 guys with guns at the rally, one white, one black. During the newscast something got messed up, the reporter was talking about the white guy while pre-recorded footage of the black guy was playing. The reporter pointed this out while this happened, admitting to the screw up. I don't think anything intentionally disingenuous was going on, just a garden variety fuckup.

New Logitech Dark Field Mice Operate On Glass

metalhed77 Re:But Five blades really is better. (225 comments)

That's funny, because my single blade, double edged Merkur Heavy Duty has blades that cost ~50 cents (for top quality blades) and it shaves better than the fusion I used to use.

Those Fusion refills are ridiculously priced, at lots of markets they put em behind locked glass. That said, the fusion shaves better than a 2 bladed cartridge razor, and there's no learning curve.

Most Expensive JavaScript Ever?

metalhed77 Re:So who was it ?? not (405 comments)

I've run it on windows in FF and had issues as well, even with Java installed. Of course some of my DRACs are fairly old, but even the DRAC5s have been problematic for me. Maybe I need to update the firmware, an operation which, surprise, doesn't work right on ubuntu (Dell really only supports RHEL and their firmware upgrades sometimes refuse to work on ubuntu).

Most Expensive JavaScript Ever?

metalhed77 Re:So who was it ?? not (405 comments)

Ah yes, Dell Remote Access Controllers have a shitty as hell web interface that only seems to work in IE. I think it's supposed to work in firefox but it never has for me.

Firefox 3.5RC2 Performance In Windows Vs. Linux

metalhed77 Re:My problem with Firefox is this (240 comments)

I read somewhere that's because Flash video decodes to RGB while X likes YUV video, so flash video can't use XV. If you try playing any video without XV it'll be slow and stutter.

That said, for some reason flash video plays much better on my nvidia card at work than my ati card at home.

Mayo Clinic Reports Dramatic Outcomes In Prostate Cancer Treatment

metalhed77 Nice analogy (122 comments)

The idea: use androgen ablation or hormone therapy to ignite an immune approach â" a pilot light â" and then, after a short interval of hormone therapy, introduce an anti-CTLA-4 antibody that acts like gasoline to this pilot light and overwhelms the cancer cells.

Fry: Usually on the show, they came up with a complicated plan, then explained it with a simple analogy.
Leela: Hmmm... If we can re-route engine power through the primary weapons and configure them to Melllvar's frequency, that should overload his electro-quantum structure.
Bender: Like putting too much air in a balloon!
Fry: Of course! It's all so simple!

Does Dell Know What Women Want In a Laptop?

metalhed77 Why this is both stupid and offensive (669 comments)

The reason this is stupid is because none of those things really have anything to do with a computer.

The reason this is offensive is because it shows how dell thought women were too stupid to recognize this.

The Global Warming Heretic

metalhed77 Re:His story is typical. (1190 comments)

Any time someone has a dissenting opinion against a liberal the liberal only seems capable of defending their argument with insults and threats.

Ummmmm, every ideology has a subset of people who behave this way.

Saying stuff like this helpfully labels you as being the kind of rabid fundamentalist you're accusing your opponents of being.

"Slacker DBs" vs. Old-Guard DBs

metalhed77 Re:Laziness Rules (267 comments)

I know most of these comments aren't too serious, but oddly enough his experience with notes is part of why couch has turned out so well.

His experience with notes is pretty relevant as notes and couchdb are both document oriented databases. CouchDB is VERY different than notes in a lot of ways, Damien designed Couch with a lot of the problems of notes in mind. So, you can think of his time with notes as time he spent learning what not to do.

IBM funds CouchDB development through Apache paying Damien. They initially wanted him to work for IBM as a regular employee he told them he was unwilling to work in that corporate structure, leading to the current compromise.
