PDF/PPT downloadables were provided during the all-day session and supposedly all the A/V content (the actual recordings / transcripts) will be available on the RedHat site for 3 months after they are posted... as with all interactive presentations there was a lot discussed that wasn't on the slideshow.
I don't have that many GUI users on Linux, they all connect using terminal emulation via ssh/telnet etc so I can't help much.
Assuming the parent processes aren't easily understood / identified, a tool such as SystemTap may provide more information to enable you to debug the issue. It's not terribly complicated to setup and in many cases provides extra detail you can't get easily or at all, even using tools such as oProfile.
it becomes trivial to sort through all the crap out there and skim the sweet delicious cream from the top of the Intarwebz (ewwww....)
For many things it's not trivial. For instance, have you tried locating apps in the App Store lately? To say that it's tedious doesn't do it justice -- way way way too many choices that aren't relevant. I recently looked for a free painting program and after trying various forms of paint, draw, edit image etc I eventually had to use the term "sketch" to find what I was looking for. It was just dozens of pages of crap, many of which had nothing to do with painting / drawing. For my purposes these were synonyms yet to the search engine they were not. And yes I tried Google also, and again there were so many hits, many outdated, that finding "real" content was a problem. So many dupes that I couldn't easily tell what options I had.
As another example, commonly-used terms such as OpenOffice's Calc or Write -- try searching for those and see what you get. Or OO Draw. How about tips for MS Paint?
We need a semantic web because so many of the content is based on keywords which are either inexact or are also commonly used words. We need to be able to grep the web in a more efficient manner.
The difference is that in the case of Pearl Harbor, an actual government was responsible. We could identify and fight that enemy. In today's Iraq / Afghanistan mess, no government is responsible, just a bunch of extremists.
There is no way to "win" when you're talking about a handful of extremists, when you kill one group another pops up. Their "goal" is to achieve destabilization and they're happy to die in pursuing that goal. We will find no end to these wars because of this. You can't fight suicide bombers with an army, the best case is to make yourself uninteresting as possible rather than keep stirring them up, while increasing security at our borders. We have no idea how many of these people are already in our country, more keep popping up every day.
I attended the "Red Hat Virtual Experience" today; their offering seems to have a leg up on the ESX solution. Load balancing is only one of the features. Patch management can be accomplished through Red Hat's web interface, where you build templates and install companywide as desired. I'm getting ready to demo it on our blades to see how it compares. Have you taken a look at it?
Have you considered a nightly job to rar your home folder on each machine and rsync it somewhere else? That's what I do; you can delete my entire home folder anytime you like and while I may lose that day's work I have 3 weeks of nightly backups on tape, and last night's live copy on at least 2 other servers. But then again I'm a programmer and my code and documents are very important to me so I can justify the trouble of setting this up.
Or those of us who finance those programmer types. I may be a lot of things but I'm not an expert at tweaking kernels or rewriting MySQL. There are people who do that simply because we pay them.
That's a HUGE difference from a closed, proprietary system where no matter what unless you're the 800-pound gorilla and can strongarm yourself into a copy of the source you can't fix the problem even if you totally understand it.
Personally I don't care if Linux is ever employed by the "average person". I'm not one of those people and the work I do requires people who know what's going on. Linux gives me the fine control to get in there and tweak things that Windows will probably never have.
You can make a machine smarter, but people keep getting dumber all the time. At some point you just have to say to those people forget it, you're not going to learn, you're not worth trying to explain it to. Here's your Etch-a-Sketch.
If you don't understand the distinction between the security models that Linux and Windows employ, you might want to do some more reading. I don't know who modded you insightful when it's pretty obvious you don't have any idea what you're talking about.
To break it down a little for you, when a user installs something manually and introduces a vulnerability, that's quite different than an open-by-default service and/or built-in web browser (IE) allowing something to be installed without user notification or warning.
I use Windows, OS X and Linux daily at work and based on your previous comments you should be calling no one a zealot except yourself.
In my area (Southeast Florida) there are a great many areas where no coverage is available, and also a great many where signal strength is low. In these situations the iPhone (BlackBerry too) lowers throughput. The solution for people in my situation is to add towers -- the existing towers are too far away to provide coverage. Maybe once we have decent metropolitan coverage we can start worrying about bandwidth.
And no, Sprint sucks too. I'm on my AirCard with 1 of 4 bars... and I'm in a very large city in a county with more than 1.2M people. Going outside to the front or rear of the house sometimes gives me 2 bars. A $35 amplified antenna didn't help either. The iPhone gets 1 bar inside the house most of the time and 3 bars outside, better but sometimes it's in the "E" network instead of the 3G network.
The problem with usage fees is once people become accustomed to them, it's easy to ratchet down until you're paying extra for practically everything.
I think in this case AT&T better let everyone with an existing contract play out the rest of their 2-year contract without major changes or they will be hit for a large class-action suit. They'd be best to stop advertising plans as unlimited and change pricing only on new plans, and be more careful with their wording in the future.
You pay extra for texting on an iPhone? I understood my monthly bill (I don't pay it, my employer does) would be the same as we pay for our BlackBerry's. I was told to use it as much as I wanted, all long distance, text, data etc is included for roughly $100 per month.
Although there might be a little asterisk or other such foolishness, all it takes is a decent law firm to convince the jury that the average person was reasonable to believe that "unlimited" meant "unlimited" and then AT&T will be unhappy. AT&T shareholders won't like that either, so upper management will likely let this come to a boil before they try to do anything.
I know in my case, the iPhone was purchased on a corporate account and absolutely no paperwork was provided to me / signed etc so good luck with those asterisks. I was told I would have an "unlimited" data plan and use it as much as I want. I do.
AT&T is going to mess around and get its fingers burned playing with this fire.
Another option is to stop advertising "UNLIMITED" access for new accounts, allow the existing accounts to complete their 2-year contract (a lawsuit would bring only MORE bad publicity and potentially huge costs -- since "unlimited" was in fact was what advertised), and change the terms at that time. For all new users create options to pay per MB after xx MB/GB. Everyone's happy then.
You have to stop the bleeding before you can begin the transfusion or you're just screwing around.
Umm... I hope you're joking. The PDF spec is well-documented and pulling info out of a document that isn't secured is trivial. One proper method is to use the built-in redaction tools present in Acrobat 9 Pro.
There is a built-in redaction feature in Acrobat 9 Pro. It saves you the trouble of photocopying the original (maintaining fonts / text / graphics etc in their full quality). We looked into redacting info on PDF's and I was pleasantly surprised to find Adobe had added the feature. Options include choosing the redaction text.
Those sound nice -- I wish I had a load that was CPU bound to test them -- although they are considerably more than what I'm paying for the dual 8-way 460c's with (8? 16? GB RAM I forget how the last few were bundled). I get them for around $5k each which is practically nothing (compared to the $12-15K we spent on DL380's and the huge expense of the MSA30's only 5 years ago). The memory costs the most, so while we still have slots in the cabinet available, we will probably buy blades then go back and consolidate / upgrade memory.
We just emptied an entire colo rack and moved all the DL320's / 360's / 380's and accompanying MSA30's to a handful of blades... and they seem to run better as VM's under ESX.
On a couple of servers we haven't been able to test them as VM's and because they're critical to our business we may not take that chance. For only $5K each it's probably not worth messing with.
Dual 8-way HP 460C blades are what I use, connected to an EVA4400. They make the quads seem slow... but then again more than half of what I need is I/O. Our production RHEL5 server typically runs at 70% idle with > 300 users and > 400 connections. It's also running a bunch of other services -- CUPS print server, XML server for the DB backend, MySQL server (mostly active in the mornings), Samba server (used lightly), etc etc.
Same setup on an HP DL380 with dual quad Xenons was 30-40% idle. CPU% from iowait has also been reduced significantly from 40%-60% to a typical 10% under the same or larger load.

The actual link we used for the conference won't help you much without a login, this was a registration-required event. The agenda is here: http://www-2.virtualevents365.com/rhexp/agenda.php . The best public area is probably http://www.redhat.com/rhev/ .

Oh, and the current version is super buggy. Probably because they fired the entire development team after the last release.
Yep, there's military intelligence for you. I tried the game twice several years ago and it was horribly buggy then. I see some things don't change.

Guess that depends on what the malware does.

Lazy much?

Who knows, maybe Dan East is working for the Feds and thinks this is a tech support line.
