So, it looks like you have to actually be logged in (or su'ed in) as root for this to work -- sudo doesn't cut it. Don't know why. Also note that I use 'sux' instead of 'su'.

Anyway, he presented a couple of common misconceptions about Linux. I think the most common one is that whole command-line thing. Here are my comments posted to his site:

Okay, so, yeah, sticking in a paragraph that makes it look like I am not biased -- the Windows is good for some people paragraph -- is maybe a little obvious bias-cover-up. But whatchagonnado? When one finds something that one loves, one wants to tell the world, doesn't one? But really, the part that irks me the most about Windows users' comparisons of Linux is the generally outdated and incorrect comparisons.

I will admit, Linux can be a bit confusing. The vast number of choices is really quite overwhelming. So from here on out, I'll try to stick to comparison by using a particular distro vs Windows, and not "Linux" which really covers a lot more territory and at the same time is a lot more granularly specific than the term "Windows".

So for future posts, it is going to be LinuxMint vs Windows. I was going to go with Ubuntu, but as far as comparisons of interest to "averege" users go, LinuxMint levels the playing field even more than Ubuntu, with its out-of-the-box software choices.

…Duplicate entry ‘0’ for key 1 …

Where the elipses are the specific INSERT statement and MySQL error number. Not relevant, here, because this was not caused by NucleusCMS or MySQL.

I discovered that my MySQL server instance had been recently upgraded by my ISP. I think this is the source of the problem, but I am not certain. At any rate, the real problem was that the auto incrementing ID for the content table, "prefix_nucleus_item.inumber", had been changed to not be auto incrementing. WTF? Anyway, the solution was easy:

Alternatively, this can be accomplished with something like PHPMyAdmin. Or by creating a PHP script with this one liner in it (a real pain but the only solution available for some ISP situations). But you do need direct access to your MySQL tables in one way or another.

NOTE: "-rotate" is optional! duh.

Okay, so, I really frikin love LinuxMint Daryna. That's LinuxMint 4. Actually, though, it felt like Mint 3.1 was a bit better, more polished, I don't know, friendlier, than LinuxMint 4. Anyway, that's neither here nor there. The point is, Daryna is pretty effin great. Really.

Also, I have always felt that Ubuntu, while sound of concept lacked a smidge in the execution department, and that is where an OS like Mint really shone: in the finall fit and finish of the OS.

However, Ubuntu 8.04 may just prove to be the very best Ubuntu release, nay, the best Linux Desktop Distribution release ever. We'll see.

Okay, back to Daryna. I think Mint is absolutely fantastic. But, unfortunately, some things just plain dain't work right on my rather new Lenovo Thinkpad R61. Wireless? Worked well. Built-in webcam? Worked great. But things that I really really want to work perfectly on a laptop did not. One major, the other minor: Suspend/hibernate and the trackpad.

Now, in Ubuntu 8.04 -- and this isn't the final version even -- the trackpad works perfectly, and suspend/hibernate has worked so far out-of-the-box. Flawless.

Oh, I just remembered another thing that was a bit dodgy in Daryna on this laptop: LCD brightness. Didn't work at all. Well, the screen brightness buttons did something -- they caused the brightness OSD to show up with what the system thought was the actual brightness -- but the brightness never changed. Now, however, all of the power management functions, including screen brightness, work. Perfectly, in fact. In fact, I don't think there is anything that doesn't work!

Other things that are really cool about Ubuntu 8.04:

• Screen configurator actually worked! It detected the external monitor, and had a neat little GUI that let you drag around the positioning of the connected monitors -- left of, right of, top of, etc. or cloned. Admittedly, this GUI was a bit buggy! But it did work and did not crash. Just quirky bugs.
• FireFox 3 is fucking fast as hell
• Actually, *everything* is faster. This is just subjective, but everything just seems to run faster: nautilus, VMWare (when I finally got that running), FireFox 3, etc.
• Actually, actually, not just speed, but FireFox 3 is better -- way better -- than FF2 in almost every respect. System integration is better. FF3 is faster. FF3 does popups, dialogs, and notices better (Take the "save password now" dialog. Before FF stopped and waited for you to make a decision on save now or later. Now, FF continues on through to what you were doing -- browsing a website -- and, if you want, you have plenty of time to click or ignore the very unobtrusive "save now?" dialog.)
• It was really easy to just add all the "extra stuff" -- MP3 playback, Java, video codecs, etc, with the "ubuntu-restricted-extras" meta-package. I don't know when that got added, all I know is that I don't remember seeing it before 8.04. (Automatix anyone?)
• Holy crap, even the little things that didn't seem to work before now work perfectly. NetworkManager, always a cool feature since 7.04, now is even better than ever. You can look at and edit the saved wireless access points. The VPN plugin worked perfectly for me. did you get that? PERFECTLY. No making a shell script to log on to my VPN -- NetworkManager just takes care of it! Mind you, I am useing another thing that worked perfectly and easily, the "vpnc" Cisco VPN client. (I think in my previous job, for a Large University, I couldn't use the vpnc client only because the buracracy there did not allow peons to configure their own VPN clients, and to use vpnc you really need to have the Group and User passwords. But I digress. Also, I have no way to test this anymore. Don't work there! (yay)).

I do think that some things need to get changed at the level of "choosing which packages belong on the CD" level. Like Evolution, a shitty, buggy, unstable, clunky app. (Does anyone actually use Evolution except Novell employess and the Evo developers?) Mplayer browser plug-in is way better than Totem's browser plugin. And Amarok? Waay better than Banshee or Rhythmbox. And where is K3B? I think Ubuntu draws lines between its core disto (Gnome-based) and the "official derivatives" (KDE-based Kubuntu, and XFCE-based Xubuntu) a little to tightly along Desktop lines, and there are simply some KDE apps (or just non-Gnome, e.g. Thunderbird) that are better than their Gnome counterparts (and Gnome apps that are better than their KDE counterparts). And that is another thing that LinuxMint does so well. Mint does not just "add codecs" to Ubuntu. Mint goes in and tweaks packages to make choices by what works best, irrespective of Desktop environment.

Anyway, I hope the Elysa release is as good as Ubuntu 8.04 has shown to be so far. It hasn't been all roses, though. The biggest problems so far are:

• NVIDIA drivers work well, when they are being used, but cause problems with other stuff, like the aforementioned screen configurator and with suspend/hibernate. Among other things. A non-issue for me at the moment as I can do without 3D acceleration. But it would be nice to have, certainly! I'll look into it...
• The screen settings get remembered across reboots BUT I have to remove the external monitor when I reboot! Or else I just get a blank screen -- on BOTH monitors! The laptop is running, mind you, it is just the screens that are blank. The workaround (sucky) is to remove the external monitor, reboot, and reattach the monitor after boot has finished. It is weird and doesn't make sense because the boot splash can even be seen on the external monitor when I have it plugged in during reboot, but something gets screwed up right as the boot sequence is wrapping up. This problem is definitely the worst one I've run into so far and I wouldn't have even noticed it at all but for my need to use my awesome, huge, fantastic external monitor.

The solutions for both of these problems are not too bad: just don't use the NVIDA drivers (of course, then there's no compiz), and do the reboot workaround.

Update: Not everything is so rosy.

Okay, so, there is this bug. Oh, well, not everything is perfect. The problem is with Pulseaudio and the solutions are

• Remove Pulseaudio
• Change default sound server to something else
• 'pulseaudio -k' when the bug occurs (i.e. kill pulseaudio). Then, maybe, just maybe, start it up again.

Not a showstopper for me, but very, very annoying.

Anyway, that said, I just want to list reasons why I think F-Spot sucks monkey nuts.

• Poor performance. Lots of images? Well, expect to wait for lots of time while F-Spot figures out what the hell its doing. (Is this F-Spot or Mono's problem? I dunno)
• Shitty interface. While touted as being "easy to use" I find the opposite to be true.
• Wants to, while importing photos from somewhere, wants to copy them to the Photos directory. I just plain don't want bajillions of copies of photos around. Why can't it at least remember that I have un-checked this option every time? I just want to import them into F-Spot's management database, not into where F-spot thinks I should save everything.
• Zero flexibility. If F-Spot does what you want it to do for you, and you like the way F-Spot does it, then fine! But if you want anything different, F-Spot ain't the way to go.

Actually, this last one shows up in Gnome apps all the time. Easy-to-use is not synonomous with inflexible or with no features. But the Gnome project seems to think so. At least, that is the view that is projected in the pantheon of Gnome apps; maybe the philosophy is different, but I can't tell. KDE is much better in this regard -- most KDE apps are bubbling with advanced features that you don't have to use. But it is true that many advance configuration options for Gnome apps can be found in their gconf configuration, and using the gconf-editor. And once I found that out, I found Gnome in general to be a lot more appealing.

Okay, short post, but there you have it.

Example:

Wow! It actually worked!

Oh! Here, I found the problem: http://tracker.moodle.org/browse/MDL-6513

The soltuion, on Linux at least, was easy! Use the "--bind" option for mount to mount a directory on top of another directory.

Why is my DirectoryRoot in /home? Well, I love tinkering with my box and installing new distros. I put /home on a separate, big, disk partition. Then I put everything that I want to remain unscathed from an uprade into /home. That's really all. Makes upgrades really quite easy and painless.

Also note that this mount point does not get mounted automatically after a reboot! This is not in /etc/fstab, and I don't think a --bind mount can be put in fstab! To get around this, just put the one-liner in /etc/rc.local. (It seems that Ubuntu does now include rc.local, even if Debian does not. When did Ubuntu start carrying /etc/rc.local?)

Fix was this: adjust "Capture" levels to let Skype get the sound input. "Capture" mixer is evidently a different mixing channel altogether and Skype uses that. Plus the "Mic" channel. For me, on my R61, I also have "Internal Mic", "Docking Mic", "and "X Mic Boost" (where "X" is one of the three microphone channels).

Steps:

1. Double click Volume applet.
2. Go to Edit->Preferences
3. Click the checkbox for "Capture". This adds the newly visible "Capture" slider in a newly visible "Recording" tab.
4. Un-mute "Capture". Slide it to the top.
5. And finally, in Skype, go to Options->Sound Devices and UN-check the "Allow Skype to automatically adjust my mixer levels" or else your Capture mix will jump all over the place. To a bad, way-too-low place.

Done!
