totem-video-thumbnailer at fault?
Close Nautilus, the file-system browser that you’ve got open on the directory where the files are being downloaded. It file is constantly getting pinged as having been updated, and so it’s getting thumbnailed over and over again, to no end.
Note your download speeds may improve after this fix.
I’ve run the Google Chrome on Linux beta since it first become available, and my impression is: slow. I might be unusual, in that I typically have dozens and dozens of tabs open, and that may break Chrome’s model of shoving each page into its own process, and this PC has “only” a gig of RAM, but it’s slower than FireFox for the same task. Things were a lot worse before I loaded AdBlock and FlashBlock for Chrome. Now my CPU isn’t pegged at 100%.
Embedded JavaScript is affected by this performance hit, so that particular tools that I have help do my stuff, well, don’t anymore.
Most annoyingly, it seems, although I haven’t confirmed it, that the back button causes a page reload: it doesn’t come out of the cache. Or the slowness could make it look that way. But how long can it possibly take to render a page anyway?
On the upside, it hasn’t crashed, and I would have expected FireFox to mysteriously die without any explanation by now (a sign that Firefox is going to die soon is that tab-swaps/page loads become very slow, indicating a similar root cause which I’m guessing is memory exhaustion). Firefox has always done the mysterious death thing, and I was hoping that upgrading to 3.5 would fix things, but no dice.
I’m trying to decide whether it’s preferable to have my browser snappy, but occasionally fall in a big pile and get back up again, or a laggard that rolls with the punches. Perhaps I’ll split my browsing between them simultaneously; vital stuff on Chrome and throw-away stuff on FF, but that’s going to be a bit tough on my brain.
[UPDATE]
Well, it turns out that Chrome is a memory hog. I bought another gig of RAM, and wouldn’t you know it, the PC is flying. My suspicions were tripped when all of the RAM was in use, most of the paging file and the little orange disk activity light was slowly burning a hole in the wall on the other side of the room.
Chrome for Linux now in Beta, which I’m sure is all over the place, but go here: http://www.google.com/chrome/intl/en/w00t.html to fetch.
[update]
You can’t change spell-check languages. But it seems to crash less than Firefox, so I’m switching. I’ll give you a yell when I figure out why this was a bad idea

For the story so far see Part 1 and Part 2. If you’re totally bored, then please don’t read on… this is the longest post yet!
So I got my Linksys NSLU2 home. I thought I’d fire it up and make sure it worked. There’d be nothing more frustrating than flashing it with the Linux OS, find it doesn’t work and then wonder whether the issue is with the new Firmware or the actual hardware.
Plugged it in, fired it up, plugged in and formatted a blank external drive I dug out of the cupboard. All good so far! I can’t plug in a disk with anything on it because the LinkSys requires disks to be formatted with EXT3.
Hmmm… what’s this… a firmware upgrade to the NSLU2 that allows it to read NTFS! That’d make the device usable until I get my head around the Linux options!
Loaded up the upgrade, all went smoothly. Plugged in my external hard drive to see if it works. Get “Drive not formatted” message in the NSLU2 admin screen, so it must not support NTFS after all. Oh well. Plugged the external drive back into my desktop PC.
“This disk is not formatted. Do you want to format it now? Yes/No”
My
heart
stopped.
An entire disk’s worth of data… gone. Video from when the kids were little, lots of photos… gone. I know what you’re all thinking… why wasn’t this data backed up? I have two responses to this. 1) It’s not that easy to back up a 14GB video file. 2) Part of the reason I was setting up this solution is to make automated backups more accessible!
Some have said that I shouldn’t have trusted the device with my data, but in my defence, it’s a shrink wrapped consumer device that’s designed to have drives plugged in to it. If I can’t trust this device with my data, I don’t have much use for it!
I kicked off a File Recovery scan and went to bed very sad.
In the morning, the file recovery had found a bunch of deleted files, but none of the files that were not deleted at the time of the corruption! I tried loading the drive up in a couple of EXT3 file viewers, but they couldn’t read the drive either.
I’d pretty much given up hope of getting my data back.
Then my neighbour nonchalantly suggests I try a partition table repair tool. I load one up and run it. It tells me “The partition table on the disk is incorrect. Would you like to fix it?” I click “Yes”. Bang. All my data is back!!!
Yay! Waves of relief! Not to mention proof that the Linksys had screwed up the disk. The partition table was written for an EXT3 disk, even though it was still formatted in NTFS.
Yesterday I took the Linksys back to Harris Technology and threw it at them as hard as I could. Actually I didn’t and they were incredibly helpful, giving me a full refund without any hassle.
So back to the drawing board. Now that I realise how precious that data is to me, I’m going to have to get a proper, RAID based network drive solution. More money 
I’ll probably go for a Thecus N2100.
Lesson the First
Imagine losing all your data that is not backed up. How do you feel about that?
Lesson the Second
No, really. Losing it. Right now. Seriously, how do you feel about that?
Weigh your reaction to the above questions against the cost of getting dedicated backup.
Here endeth the lesson.
Update: I was talking to Josh last night and he said it wasn’t clear that I hadn’t installed the funky open source firmware on the LinkSys box yet. It was running the latest official firmware release. I probably also didn’t emphasize enough that I wouldn’t recommend anyone buying one of these pieces of junk
I’ve purchased my Linksys NSLU2 
Now I want to make some modifications. The issue is that there are a number of different firmware options to choose from.
My requirements:
- Serve files for media (Basic functionality for all firmware)
- Read from FAT32 formatted external drives (isn’t provided by the base firmware!! The device requires all disks to be formatted!)
- Bittorent client
- Subversion server
Based on this comparison of different firmware options I’m going to have to look at a full linux based OS. Unfortunately I’ve never used Linux, so trying to get it to work on a small memory/slow processor device is going to be a steep learning curve.
Stay tuned for the next exciting episode.
I’ve annexed a room at my house to be my ‘den’. First order of business is getting some entertainment in there.
Requirements:
My current solutions contains the following components:
The network storage decision is narrowing down. I considered solutions such as the Thecus N1200. I dismissed this as being overpriced and probably overkill for my needs.
My current front runner is a Linksys NSLU2. It doesn’t have any internal disks, but has two USB ports to plug in external drives. The real beauty of the device (affectionately known as the ‘slug’ by fanboyz) is that there is an open source Linux based operating system that can be installed to it. This adds lots of extra functionality like all sorts of servers (print, bittorrent, iTunes, media/photos). I was even thinking I could install svn on it and it can be my source control repository.
I’ll let you know how my plans proceed. Any advice/comments would be very welcome!
A couple of weeks ago Josh posted about virtualising your overloaded, slow, not-rebuilt-for-years PC, and keeping it on standby within a new build in case you need anything on it.
How about the idea of keeping that new build clean — putting on only your most frequently used, essential applications, with everything else going onto a virtual PC?
For me, that would mean Office, Firefox, my usual web-building stuff (Photopaint, UltraEdit, Filezilla), Nero, and one or two others, such as perhaps Trillian. I’d draw a line under them, and anything else not worthy of a permanent spot in my Windows setup would be virtualised, possibly in various separate virtual PCs, setup for different roles: one for Visual Studio, one for trying out freebie apps from mags, a Linux setup for LAMP development, one for stupid software that insists on running as Administrator, etc, etc.
What to use for the virtual machines? There’s a few different options.
The freebie Virtual Server will only support Windows NT 4 and above, and only server OS’s, which to my mind would unnecessarily weigh down your virtual machines with more than they need. (Linux as a guest OS seems to be coming.)
Another option is the free VMWare Server, which will host a wider range of guest OSs.
The non-free Virtual PC will host just about any x86 operating system. If you don’t want to try the 45 day free trial, it’ll set you back A$215 or so, or it’s available via MSDN Universal.
A problem would be performance, of course. It’s not like emulating a 2Mhz 6502 under BeebEm. But then, hopefully it’s not as bad as what I’ve seen on my brother-in-law’s PowerPC Mac trying to run x86 AutoCad in Windows 2000.
Nonetheless games and other performance-intensive apps may not perform well under virtualisation, especially if they require particular hardware. And yet they would benefit the most, as they often have installers that wreak havoc on Windows setups, chucking weird-arse DLLs everywhere. As the “Virtual PC Guy” is fond of telling us, a lot of the older games run okay, but newer ones might be a problem.
Maybe the only solution there is to put them on a completely separate computer, or move up to Intel’s latest chips which have better support for virtualisation.
Or give the whole thing up and resign yourself to a slow computer with rebuilds every year or two.
I think I’ll try Win98 with a couple of recent-ish games (say, Midtown Madness 1 and 2) and see how it goes.
Linux is A European threat to ‘our’ (.us) computers proves how well trolling works.
Following the comments posted in various forums which espouse the various benefits of Linux and having a need to test a setup of “MySQL” database engine, I though, well, lets give this ‘Nix thing a go.
So these observations which follow are of my first encounter with Linux (which occurred about a month ago – early Dec). They are offered for general interest and likely amusement of the ‘Nix aware among you. These comments are longish – but contain just some of the many items I observed.
Remember, this from a person who has never seen or run Linux before spending all my time with various flavours of DOS & Windows.
Firstly, I had armed myself with a couple of different books – a copy of “Fedora Core 4 Unleashed” and a “Linux Pocket book”, both containing recent Fedora core distributions. (online download of ISO vs. Dialup? Hardly. Plus there were instructions in those books)
Then, after checking minimum hardware requirements in the books, I threw together a basic “no frills” PC running what appeared to be more than adequate – P3 600, 3/4 gig Ram, 40 gig HDD, Basic LAN card, old DVD reader, old TNT video, no floppy, no sound, no extras. It booted – good.
Loaded the DVD from the Unleashed book into the drive and hit the reset button. The Linux installer fired up & gave Text or Graphical installer options. I’m a Windows Bloke – so, naturally, I chose Graphical. Spent some time accepting defaults for the disk partitioning and making various choices about what to install. I have no idea what some of ‘em related to… but what the heck. Finally get to the “OK, now install it all” & waited….
.. till the installer crashed PRIOR to the disk partitioning step.
U-huh.
Rebooted, started again. This time selected TEXT mode installer.
After quite some time, a couple of dialogs, nominate root password and a *single* reboot (well, now, there is a plus) I was looking at a login screen. OK, so what now?
Login as root. Graphical desktop. U-huh. (Gnome desktop by default, although I believe KDE was also available – I certainly didn’t know enough to feel the need to alter their default choice). Start button (OK, or whatever Fedora calls it) is at top left, not at bottom. I can deal with that. Menu’s …. Goodo. Found a menu item to create user accounts. Umm. Made a user account – yeah, I know you shouldn’t use root accounts for general work. Bloody hell, I wanna share with my Win network, but it would NOT let me create a Login that matched what is already in use on the Win network – I currently use, my logins have a space in ‘em… like “Dave Jenkins” Nix didn’t like that. Subsequently my fears that this might cause problems were proved founded!
Anyway created new user account, validated it on my Win box, logged in to Fedora with that.. righto, so now what? From a shell (what, coloured background by default… ummm different) established that MySQL had loaded, and from MySQL docos got the server process running. Great. Now to share it on the network.
Network sharing? Samba, right? Well, frig me, if it didn’t take at least 4 – 5 hours arsing around before I could even get the thing to see my Windows network, let along get it to be able to transfer files back & fwd. At one point, late the first day, I could see Windows shares from Nix, but not the other way. I turned both PCs off and started again the next day – only to fine that, without any further setting changes, Windows could now see ‘Nix shared folder. U-Huh. I cannot explain it – maybe, at that time, like me, the PC had had enough. Combinations of needing new logins created on a Windows box, along with some funny settings (I’ll prolly never find again) which match Windows/sambo logins with local IDs… Certainly it was not easy. I knew that I need to set certain IP settings to what values, but ya think I could easily find where? Of what the new terminology was?
Then to Printers….
Several attempts with different (why would you have several seperate ways to hook up a printer?? At least one I know was referred to as “CUPS”) setup tools, I finally found I had to BLINDLY enter the mappings to the location of the PC/Printer name, ‘cos Nix would not show the printer even existed until AFTER the password access to the printer had been validated. Security, bah… Anyway, I finally got Writer (OpenOffice) to send a formatted line of text to my Windows Printer.. although I did not understand, nor bother, about the cryptic error in the dialog I received AFTER the print had been generated.
And speaking of Security….
Bloody hell. I know many, if not most will want and need a *secure* PC to protect from nasties. In this particular case, I did not. Quite the reverse. This was to be used to test on a local controlled private network. It would never see Internet or unknown source disks and so would not be at risk from foreign nasties. Ya think I could find someway to turn off the high level of security? Fat chance! Every time I tried to do anything I was prompted for the Root Password. Got to the stage where I gave up and was logging in a root to avoid this problem. I couldn’t find a way to get the thing to auto-log in. And I never managed to unbar the ports that MySQL used so I could get to it from a Windows box.
And what’s with everything being configured by TEXT files? Every item in the books say launch this or that config file… (which, when finally found and opened, all, remarkably, look like “ini” files). Now didn’t Windows move on from config by ini files about a decade ago? And unlike the old system & Win inis, it seems to me that there are bazillions of those config files… and not all in the same place either.
And a bunch of other things. A simple “Dir” in the shell doesn’t work. I know its different, but why does EVERYTHING have to be different at the command prompt, but appear like Windows in the GUI? Windows CLEARLY displays my different drive volumes – yeah I s’pose you’d get use to the “mount point” system… but I like my drive letters. Why doesn’t a DVD/CD get auto recognised when you are logged in at the command line? Manual mounting? How quaint…
Open Office “Write” initially looked like Word. Could get to work straight up in there. Ditto for whatever the Excel replacement was (Calc?). GIMP? I’d expect to need a bunch of time to get used to their idea of an interface. Gnome desktop – I could find NO WAY to alter what items appeared in their Applications menu. Further, installing more apps from the disk using the GUI installer changed NOTHING in that menu. I’m not saying it can’t be changed… it’s prolly in a config file somewhere!
Summary: You want to “get to work” straight away? Then stick with what you know. If you want to learn something VERY different – then by all means, try Linux (or Unix or FreeBSD or…). But do not believe what you may have heard that “it is easy” or “you will be up and running quickly”. Expect to take a long time before you’ll be productive. I think some of these “it’s easy” comments may come from people who are familiar with Nix but who have forgotten the various difficulties they first experienced. Remember your first System.ini edit? Or your first venture into ANSI prompt commands?
After this little adventure, I then hear that this, that or the other flavour of Nix would have been better because…. <insert reasons> Well, I am not so sure.
After all that, yeah, I’d have a similar bunch of comments if I was an old UNIX user trying Windows for the first time. I’m not trying to say that Nix doesn’t have advantages or that Windows is better. All I’m trying to say is that there is a *considerable* learning curve to the change.
Two parting comments:
1) After chewing up the better part of two full days (about 1 month ago), that particular Nix PC has sat idle – I’m back to my comfortable and familiar Windows world.
2) The MySQL test install which prompted al this? I dropped down a Windows version, installed it to a XP “server” box, and was up and running remotely from my Windows desktop creating tables and queries *within an hour*.
So, you Nix people, go on, have your chuckle. Now is where you tell me all that I did wrong….

My 7-year-old son Jeremy shows a fascination for computers. He’s a pretty skilled Windows user (it’s what we run at home), and loves using my sister’s Mac laptop when we visit her. So I thought I’d show him Linux, in the easiest way possible: a bootable version.
Knoppix was tried first. The BitTorrent download (yes, there is a legitimate use for BitTorrent) came down the line at a blistering 150kbps. Simplicity itself to burn the ISO to a CD using Nero, and chuck it into the older of my two PCs.
Alas, ’twas not to be. After doing the auto-configuration thing, it stopped dead. This turned out to be my video card, an aging Diamond Viper V-550. Theoretically a good card (well, for five years ago), it’s hampered by a lack of support, not only from Microsoft via DirectX, but also apparently from Linux distributions. (I know they can’t support everything, but it’s particularly galling with DirectX, because earlier versions worked okay with it, and once you’ve got an incompatible later version, it’s impossible to downgrade, unless you’re feeling very brave or feel like re-installing the entire OS.)
It’s a cinch to change the BIOS settings to disable the Viper, and go for the on-board video, of course. Plus plug the monitor into the other socket. Just not quite the seamless experience I was looking for though.
It did boot up then, though the other thing Knoppix didn’t like was my USB mouse, so it was keyboard-only. Somewhere I have a USB to PS2 mouse adapter, which I can use for this.
By contrast, Knoppix booted up flawlessly on my newer PC, which evidently doesn’t have an orphaned graphics card and a weirdo mouse.
(Though when I rebooted into Windows XP, oddly it thought initially it had two monitors. Coincidence? Maybe.)
I could fiddle with Knoppix to get it working on the older PC, but time constraints and laziness may mean I try other bootable distros first. Other contenders include Ubuntu and Damn Small Linux.
Though now I come to think of it, if I want to do a bit more LAMP dabbling, I should look for something more permanent.
So, I’ve been using Fedora Core 3 (I really must upgrade to 4) and I’ve noticed that SSL – ie HTTPS – is really slow. Logging into eBay took something like a half hour. I consulted someone who uses FC3 as their primary operating system and his suggestion was to disable the firewall. “but…” I protested. The response was simple: “Stop being such a pussy. You’ve got a firewall in your modem.” And I do.
So I did – Applications | System Settings | Security Level got me to firewall configuration, one option of which was “forgetaboudit”. A reboot of the iptables (iptables is the linux firewall: very sophisticated, very powerful, very fragile, requires a detailed understanding of IP protocols to use correctly) later – either by a command line entry (simple – just enter service iptables restart) or a system reboot (easy to remember, but takes a fair old time – FC boot time is longer than XP’s) and the firewall’s behaviour was changed. Then secure logins went just as fast as straight HTTP, and it was clear that the Red Hat Firewall was the culprit.
Hours of searching the web revealed a suggestion for a change to the configuration file, which I went to implement in a restarted firewall – and it was already there. So, to make Firefox – or any other web browser – do fast SSL when it was going slow – you need to disable, then re-enable the firewall. You can do that by picking Applications | System Settings | Security Level from the menu, disabling the firewall, opening a terminal window and entering service iptables restart, and repeating the process but enabling the firewall this time (ensure you have web turned on).
In FC3 the default firewall install doesn’t like HTTPS. And I thought Windows was freaky. I understand the FC4 doesn’t do this crazy shit.
