Fanboyism has its place but most of that type of thing came and went here years ago. Eventually you get to a point where you just want stuff to work.
Thankfully most Linux environments give you that nowadays. Manually configuring refresh rates in X11 and compiling features into your kernel are so 20th century.
So, I had to go online and found some awkward tutorial on how to configure it. That wasn't so bad, but the awful part was trying to get it to work with WEP/WPA/etc. For some reason I could just never get it to work properly so I got so frustrated with it that I configured the router to have no passwords and be locked by MAC Address.
I don't understand why the wlan0 would show up in iwconfig totally fine, but not in gnomes configuration utility and why would linux make it overly difficult to setup WEP/WPA from the command line?
First rule of WIFI under Linux: If it doesnt work out of the box, replace your WIFI card.
Second rule: Feck all the desktop specific gizmos and gadgets.
I use plain old wpa_supplicant, that is what is run under the hood probably by all other managers too.
And it actually has a gui and a tui: wpa_gui and wpa_cli.
my last fiddlings all have been about the RFKill and friends...
is the device up, is the radio enabled, is the whole card disabled by rfkill, sometimes rfkill even switches bluetooth & wifi with the same pushbutton cycling through them.
and... for shure... are the binary firmware packages installed.
OK, that was more interesting in my head. Carry on.
Subject: My experiences with virtualization
I used BBSes from 1982 - 1996 or so on Atari 8-bit and Atari ST. I was on here a few years back but the account had gone away. I listened to the fairly recent Security Now audiocast and decided to get back into Uncensored/Citadel. For my hobby and work email I've been running the OCS version of Zimbra for the last 5.5 years. I wasn't aware of the modernized Citadel when I got into Zimbra. I hope to use my own instance of Citadel at some point in the future. I'm a long time Red Hat (1996) fanboi and prefer RHEL/clone on servers and Fedora on desktops.
For virtualization, I prefer OpenVZ when it is appropriate for the task. Then comes KVM if the machine in question has VT in the CPU. If it is a 32-bit only system with no VT then VirtualBox.
The most OpenVZ containers I've had on a single machine is 1,000 but that was just testing. So far as containers that have actually been used... about 50 or so.
The most KVM VMs I've had on a single machine was about 40... all desktop Linux systems accessed via SPICE. That was for a sysadmin class.
oVirt is basically the upstream project for RHEV. I tried RHEV when it required Windows 2003 Server, IIS, and MS SQL server and Internet Explorer to run and use the management interface. Most of that changed in 3.0 and more is coming in 3.1. The design is too clunky and requires too much fancy hardware for me.
I like Proxmox VE but I'm not a Debian user. It seems kind of strange that PVE is based on Debian because Red Hat is king of KVM and OpenVZ bases their stable kernels on RHEL kernels. The PVE developers aren't familiar with rpm-based distros. Their choice of perl and not using libvirt was also fairly radical too... but I respect them for it.
I only have a few dozen VMs to worry about and don't really need any of the fancy features so vzctl and virt-manager work well enough for me. I'd love to see Proxmox VE made available for rpm-based distributions, based on libvirt, and support the SPICE protocol... but I won't hold my breath.

Subject: Re: My experiences with virtualization
From what I've read, SPICE is part of the PVE 2.X roadmap. I seem to recall they wanted it to be part of the 2.0 release but that definitely didn't make it in yet. I doubt we'll see an RPM-based version though; they've pretty much built the thing as a Debian spinoff.
Thanks for your insights.
My problem right now is, that things as Proxmox and Opencloud and whatnot are whole distributions for the single purpose of getting many VMs up and running. You'd need to add more infrastructure for other tasks, probably requiring more hardware.
I am often confronted with (very) small businesses, run by really miserly people: architects, dentists, you know those people with a very low income... They need some fileserver, some other comfortable things (Outlook sync, other fine things you get for free on linux) and the odd networked tool running on a windows "server" (XP Home edition...).
So, basically I need a host linux which is long term supported, can run some stuff like apcupsd, openvpn and kvm. Now this is all possible, but in a heterogenous environment where every user runs windows, I need some small graphical frontend for the VMs so that the windows dude can restart a VM. virtmanager for windows is cli only, X11Forwarding via putty and XMing a little tiresome.
And the web based guis are rather huge or inexistant. But after some digging around I found:
http://karesansui-project.info/ for KVM/Xen (tarballs are oooold, but git seems active with recent commits)
I will test the latter soon, will give feedback then.
Subject: How To: Download Kid's Educational Shows from YouTube in a free format
It seems a lot of children's educational shows have been posted to YouTube. It isn't up to me to decide if them being there is a violation of someone's trademarks or copyrights. If they are there, I can use youtube-dl to download them.
Want "Magic School Bus" season 1? Many Linux distros provide a package named youtube-dl. I went to wikipedia and looked up the Magic School Bus episode titles for season 1 and then I searched for those on YouTube. Then I made a text file and put in the URLs like so:
youtube-dl -f 43 -t 'http://www.youtube.com/watch?v=oBp68rhT_Sg'

Don't forget to chmod 755 that text file and then you can run it from the commandline. I hope you have some disk space. Each episode is about 130 MB or so. You'll get the webm flavor. Most everything on YouTube is available in several flavors including webm.
I haven't looked for all of the other episodes yet but will soon. You can also find a lot of episodes of PBS' Arthur show. My 6 year old really likes that one.
The quality of these videos is not really that great when played back on a computer monitor with high resolution or an HD TV... but playing them on my Nintendo Wii (with Homebrew's WiiMC application over a samba share) on a standard def. TV, they look just as good as anything else. We do not yet own an HD TV.
youtube-dl is a fantastic program and it can even download complete YouTube channels and/or playlists.
Subject: Re: How To: Download Kid's Educational Shows from YouTube in a free format
I'm playing around with it now and it confirms something that I've suspected about YouTube for a while -- they deliberately throttle the download speed to something that can easily keep up with the video, but is obviously not the top speed the network can deliver. It's optimized for streaming, not bulk downloading.
So it's definitely a good idea to batch everything up in a big script like you did. Maybe run them all in parallel.
Subject: Fedora 17 released today
Since I'm a Fedora fanboi I thought I'd mention that Fedora 17 was released today. I started using it shortly after the beta came out several weeks back. I have made a remix that includes GNOME, KDE, LXDE, XFCE, and a few others... and lots of desktop apps... and Flash, Google Chrome, and a few other things. I've been remixing it since like Fedora 9 but I haven't really registered it with DistroWatch... because do we really need more distros? Also I haven't really done any true customization... I've just added a few extra repos (rpmforge and google) and pre-installed all of the software I like on my machines. I call it MontanaLinux.
If anyone is interested in it, please let me know and I can share the URL. It is a LiveDVD that is about 1.8GB (email@example.com)
Subject: Re: Fedora 17 released today
I would be interested.
Installing Slackware 13 on ESXi - bring back a lot of memories. I know a bunch of you like other VM hosts, but I'm kinda interested in playing around with different distros, and I don't have to worry about trashing the base OS. And Slackware because I kind of feel like my Linux mojo is rusty, and this is what I learned it on, and seems like a good place to re-learn.
First task after my install is completed (later) is to move my Citadel installation over.
Subject: Re: Fedora 17 released today
You can find it here:
I rebuild it and rev the number usually every week or two... as updates come out. Our network sucks sometimes so I recommend using "wget -c [URL]" from the command line to downloadi it... so if it times out you can continue it. Of course that assumes you have Linux already. Building a Fedora spin or remix is actually very easy and the scripts used to build MontanaLinux are included in /root/livecd-creator/MontanaLinux/. KDM/KDE are the default but of course you can pick what you want from the session selector button that is part of the login screen.

I have no issues with you picking whatever virtualization platform you want... but I did want to clarify what I believe to be a perception you have from your statement. Installing some virtualization products can "trash" your distro... if by trashing you mean they use a third-party module that hooks into the kernel... and that module has to be recompiled (or updated via a binary package) every time you change your kernel. Pretty much all hosted (aka a Type 2 hypervisor) virt products are that way.
ESXi is a bare-metal (aka Type 1 hypervisor) that doesn't trash your distro because it is an operating system unto itself.
KVM is kind of a hybrid. I guess technically it is hosted but I consider it to be Type 1.5... a hybrid between type 1 and type 2. KVM is three stock Linux kernel modules (kvm, kvm_intel or kvm_amd) that have been part of the mainline Linux kernel since 2.6.20... so it is a no-brainer... because it can't trash your system... it *IS* your system. Of course you do have to install some additional (almost always packaged/provided by your distro) userland pacakges like libvirt and virt-manager to use it... and KVM requires hardware support for virtualization be present in your CPU (http://www.linux-kvm.org/page/FAQ#How_can_I_tell_if_I_have_Intel_VT_or_AMD-V.3F) but other than that it is 100% natural and totally organic. :)
Then again, I don't mind poluting some of my systems with a third-party kernel patch for better quality containers (OpenVZ), but that is another topic.
