• Lexmark X5650 doesn't print (scanning works)

  - by unor

  I want to use a Lexmark X5650 under Ubuntu. When I connect it via USB, Ubuntu recognizes the device, but can't find a driver. On the Lexmark support site, you can select "Unix/Linux" and then "Ubuntu 9.04", "9.10", "10.04" and "10.10". However, all versions lead to the same driver: lexmark-08z-series-driver-1.0-1.i386.deb.sh.tar.gz (Last updated: 2012-04-13). While installing this driver, the installer asks me to connect the device. As soon as I connect it via USB, Ubuntu now adds the printer automatically. So after the installation completed, I had 2 printers set up. But I can't print anything (I tried it with both printer configurations). Scanning works fine, though. So I guess the driver installation and the device connection are successful. When I try to print something, the print job is listed in the printing queue, but nothing happens. After some time, I get an error message which starts a debug wizard, but in the end it reads something like "Sorry, couldn't find the reason". I had several different error messages (unfortunately, I didn't record them), one was approximately like "printer cannot communicate with computer". Another said that my color ink was low (which is true, but black is full). Another said there was an input/output error. I tried it with Ubuntu 11.10. Because I read that some people had success with 10.04., I installed it in QEMU and installed the driver there, too. Same problem, though. I'd like to upgrade to 12.04, if it should work there for any reason, but I read that for some people this printer stopped working in 12.04 :/ So, it would be best if the printer would work in 12.04. If that's not possible, I'd be fine with starting a QEMU virtual machine with any GNU/Linux distribution that works with my printer.

• Where does the URL parameter "?chocaid=397" come from?

  - by unor

  In Google Webmaster Tools, I noticed that my front page was indexed two times: example.com/ example.com/?chocaid=397 I know that I could fix this with the use of link type canonical, but I wonder: Where does this parameter come from? There are various sites that have pages indexed with this very parameter/value: https://duckduckgo.com/?q=chocaid%3D397. I looked for similarities between these sites. but couldn't find a conclusive one: It's often the front page, but not in every case. Some are NSFW, but not all. When one domains' URL has this parameter, often other subdomains of the same domain have it, too. Examples Wikipedia entry Microsoft Codeplex

• Installer says I'd need a wireless firmware, but WLAN works without it out of the box

  - by unor

  While installing 12.04.01 (Alternate) on a netbook (Samsung N150Plus), Ubuntu informed me that I'd need the firmware brcm/bcm43xx-0.fw. I skipped this step. If I understand this page correctly, the mentioned firmware is a WLAN driver. However, after the Ubuntu installation was completed, the WLAN worked out of the box. After a few minutes, Ubuntu informed me that there is a firmware update available, which would be the mentioned firmware. Do I need to install this? Is Ubuntu using some kind of "lite" WLAN driver and I might run into problems with certain networks in the future, if I don't use the firmware? Would there be benefits in using the firmware? (maybe longer runtime because of lower consumption?)

• Google indexed the same page under two URLs (despite rel-canonical)

  - by unor

  The Super User question "Playing mp3 in quodlibet displays “GStreamer output pipeline could not be initialized” error" is indexed under two URLs in Google: http://superuser.com/questions/651591/playing-mp3-in-quodlibet-displays-gstreamer-output-pipeline-could-not-be-initia http://superuser.com/questions/651591/playing-mp3-in-quodlibet-displays-gstreamer-output-pipeline-could-not-be-initia/652058 The first one is the canonical one; the corresponding rel-canonical is included in both pages: <link rel="canonical" href="http://superuser.com/questions/651591/playing-mp3-in-quodlibet-displays-gstreamer-output-pipeline-could-not-be-initia" /> Google also indexed http://superuser.com/a/652058, which redirects to the answer: http://superuser.com/questions/651591/playing-mp3-in-quodlibet-displays-gstreamer-output-pipeline-could-not-be-initia/652058#652058 Now, the second URL from above is the same as this one minus the fragment #652058. So Google seems to strip the fragment, which results in exactly the same page under another URL (= containing the answer ID /652058 as suffix), and indexes it, too -- despite rel-canonical and duplicate content. Shouldn’t Google recognize this and only index the canonical variant? And what could be the reason why Stack Exchange includes the answer ID in the URL path, and not only in the fragment (resulting in various URL variants for the same page)?

• When tab groups are loaded, Firefox becomes unresponsible for minutes (Unresponsive script)

  - by unor

  I have several tab groups (~ 20) in Firefox. I can start the browser without any problems. However, as soon as I … click at the "Group tabs" icon in the toolbar, or right-click on a tab and hover over "Move to tab group", … Firefox becomes unresponsible/freezes for a rather long time (more than 2 minutes). It seems to load all tab groups (it doesn't load all the pages! I deactivated this in the settings). While this is happening, I get several "Unresponsive script" warnings, like: Script: chrome://global/content/bindings/tabbox.xml:0 (most of the time) Script: chrome://global/content/bindings/tabbox.xml:418 Script: chrome://browser/content/tabview.js:400 Script: chrome://browser/content/tabview.js:522 Script: resource://modules/sessionstore/SessionStore.jsm:3578 Script: resource:///components/PageThumbsProtocol.js:79 (rare) Script: resource://gre/modules/XPCOMUtils.jsm:323 (rare) (probably also other warnings, didn't record them yet, though) On all of these I click "Continue". After ~ 2-3 minutes and 3-5 warnings, I can use Firefox again. Now I can switch tab groups without any problems. Why is this happening? How can I prevent the long loading time? Is there maybe a about:config setting I could try? I started Firefox in Safe Mode (= without any add-ons): the problem still exists.

• Thunderbird: how to move mails into correct thread? (mailing lists)

  - by unor

  I'm subscribed to some mailing lists and every day people reply to a wrong mail (or they don't reply at all), so that their mail lands in the wrong (or a new) thread. I set the mail display in "View ? Sort by" to "Threaded". Example: mailing list "Foobar": [Foobar] random topic Re: [Foobar] random topic Re: [Foobar] random topic Re: [Foobar] random topic Re: [Foobar] random topic [Foobar] I'm John Doe Re: [Foobar] I'm John Doe Re: [Foobar] Welcome, John Re: [Foobar] random topic There are two discussions, one about "random topic", one about "John Doe". The subject line changes in the discussion about John Doe, which is fine (no problem here). But the last mail should be pigeonholed in the first thread. Instead it is at the top-level. Now, how can I move that last mail into the correct thread? I tried to drag&drop it at the mail I think it should be a reply to, but this doesn't work. I think theoretically it should be possible by fiddling with the mail headers after receiving the mail, but this doesn't seem to be a comfortable way.

• Download/update webpages listed in XML sitemap

  - by unor

  I'm searching a FLOSS tool that downloads all pages (and embedded resources, e.g. images) linked in a XML sitemap (built according to http://www.sitemaps.org/). The tool should "crawl" the sitemap regularly and look for new and deleted URLs and changes in the lastmod element. So whenever a page gets added/deleted/updated, the tool should apply the changes. Some sitemaps list sub-sitemaps in sitemapindex?sitemap. The tool should understand this and load all linked sub-sitemaps and look for URLs in there. I know there are tools that allow me to extract all URLs from the sitemap, so that I could feed them to wget or similar tools (see for example: Extract Links from a sitemap(xml)). But this wouldn't help in getting noticed about updates to pages. Tracking the webpages itself for updates doesn't work, because "secondary" content on the pages changes daily, but lastmod gets only updated when relevant content changed.

• Firefox: Unload a tab manually

  - by unor

  Firefox has a setting "Don't load tabs until selected" (see How do I make Firefox 13 Load All My Tabs on Startup or when Resuming Reload). I like that behaviour. I am searching for a way to "deload"/deactivate a tab manually for a session (until I reload it). It should stop all running JavaScript functions and plugins (like Flash). The whole webpage content may disappear until I reload/re-activate the tab, but that is not a requirement. The title has to be displayed as tab label (like it is the case with the startup setting, too). The workaround would be to restart Firefox and don't switch to the tab I want to be deactivated. This is pretty annoying, of course. EDIT: Here is what I found so far (thanks, @bytebuster!) BarTab no longer being maintained (see why) BarTab Lite seems to miss this functionality from BarTab Dormancy experimental; comes with warning that it "may eat your session" Tab Mix Plus Feature request: Unload Tab feature Tab Utilites seems to offer this functionality only for automatic unloading Feature request: Add "unload tab" to tab context menu. UnloadTab removed from addons.mozilla.org (who knows why)

• Make a mosaic picture out of 900 images

  - by unor

  I have ~ 900 pictures (mostly photos) of varying sizes. Now I want to create one big picture that includes all 900 pictures in a small thumbnail-like resolution. The tool should automatically resize the thumnails so that everything fits. All pictures should be added next to each other, so there should be no border/padding. Each picture should be included exactly one time! (however, it would be okay to omit a few so that there is no empty space) I'm looking for a tool (FLOSS, for GNU/Linux) that can do the job. I tried Metapixel, but it needs an input image that should be "resembled" by the thumbnails, and it only uses a selection of all pictures. I found montage, but couldn't get a result yet, because my system was unresponsible for hours after starting it. Maybe there are some tweaks? AndreaMosaic is recommended in this answer, but it's not FLOSS (and needs Wine to run it on GNU/Linux).
