  • Games installed from repos won't start

    - by Shauna
    I'm running Natty (upgraded from Maverick) with Gnome 3 (from the Gnome 3 PPA, Unity removed), and have recently found that some of my games from the repos no longer work. When I go to start them, I get the message Failed to launch [app name]. Failed to execute child process [app name] (no such file or directory). I've so far found this on Gweled and PyScrabble. Other games (Mines, Sudoku, Mahjongg), as well as other applications have opened just fine. Gweled used to open fine until recently. Any ideas on how to fix this?

  • How long can a user remember what they were working on? [migrated]

    - by GlenPeterson
    A web application lets the user browse its screens for future or past months. The time period the user is currently viewing follows the user through every screen of the system. But users can be logged in for a month or more. After a certain period of inactivity, we will prompt the user: You were viewing November 2008 when you last clicked. Want to view the current (default) time period instead? How long between user clicks should we wait to show this message? I'm guessing somewhere between 30 minutes and 3 hours most people will forget what they were doing, but I'd love to have some data, or someone's experience to base it on. Other suggestions related to this issue?

  • Thunderbird adds ***UNCHECKED*** to subjects of GPG messages

    - by Roman Geber
    Thunderbird seems to consider it a great idea to add the string UNCHECKED in front of the subject of GPG encrypted messages. Well, its not a good idea but rather annoying. At first I thought it would be a mailserver thing, so I checked. No trace of it, anywhere. Same goes for the raw message source. When I look at it the subject appears untouched, therefore I assume its a Thunderbird thing. Does anyone know an option to turn this ill behavior off? Thanks a lot in advance! cu Roman

  • Howto have thunderbird/lightning open ics files

    - by berkes
    Some websites offer .ics files, calendar files. I would like thunrbird to open these with Lightning so it can add the events in the ics-file to its calendar. When I use /usr/bin/thunderbird to open the file with, it starts a new message with the ics file attached. I could download the file, then import it from lightning, But I rather have lightning just open the file. Is there a commandline-option for this? Some wrapper-script maybe? Should I change something in firefox?

  • Ubuntu 12.04 LTS can't add Cheese widget

    - by Burke Hodgson
    Command-line 12.04 Cheese (cheese:4144): Gtk-WARNING **: Attempting to add a widget with type GtkImage to a GtkToggleButton, but as a GtkBin subclass a GtkToggleButton can only contain one widget at a time; it already contains a widget of type GtkLabel Is there a fix so that Cheese will work in Ubuntu 12.04? The program comes up but the webcam area is black. I am running Unity 2D on a T42 Thinkpad. All programs similar to Cheese recognize my webcam as does Skype, but I really like Cheese and the error message may be ominous for other software failures.

  • From Pocket to Instapaper

    - by Michael Freidgeim
    Some time ago I’ve described the issues that I’ve had since a new version of Read It Later, named Pocket, was introduced.I’ve waited with hope for a new upgrade, but I had a huge disappointment with the latest version 16 June 2012. It didn’t fixed any of the two major problems, that I  experienced since new Pocket was introduced-  1. iPad app still didn’t show many of the saved links. 2. ability to rename articles on iPad still wasn’t restored.I’ve posted the message into their forum. They did not show my comment on their forum( I would name it censorship, not moderation), but a few days ago I’ve received an email, recommending “try logging out of the app on your iPad, and back in again.” Their suggestion helped,  but I don’t understand, why it is not posted as a recommendation on their support site.So I decided to try InstAPaper on my iPad, Previously I’ve used it for Kindle. I never considered it before on iPad, because there were no free demo and I was very satisfied with RIL free and then RIL Pro. Currently InstAPaper cost $3, so the price is not an issue.I’ve checked that it has most of features that I am using(e.g. renaming, folders) and I am quite happy with it now. Actually I am using Pocket (or RIL free) for old bookmarks( I have 1000+ stored on my iPad) and for new bookmarks I am using InstAPaper.Having a solid experience with RIL/Pocket I’ve created a list of suggestions to Marco Arment to implement.1. Some pages stored in InstAPaper have removed essential sections of the text. E.g in many blogs comments are not stored in  InstAPaper. Some pages lost almost all of important links (e.g. http://www.lib.rus.ec/a/32416 -sorry, in Russian). RIL/Pocket has 2 modes to store offline- Web view and Article view. Web View includes all links/images of the original page, but it’s very reliable. Article view suppose to strip unrelated information, but often corrupts the content. I prefer to use offline Web view.InstAPaper should also support offline Web view, in case if stripped view removes important part of content.2.  Black full screen Saving on iPad Safari is very annoying. After user pressed a bookmark, the saving has some delay and then for a few seconds prevents from reading the text.Would be better to show as message on the top part(as in Pocket ). I am surprised, that  a full screen popup was  implemented recently as a desired feature. 3.There are no comments allowed on http://blog.instapaper.com/. I would prefer to post some of these notes as comments on http://blog.instapaper.com/ rather than write them in my blog and then send link to Marco.(I found recommendation how to add support of comments on tumblr at http://www.tumblr.com/help, but then realized that Marko was the lead developer ofTumblr.)4. Also there is no support forum. I understand that maintenance of the forum ican be a hassle, but stackexchange fSome time ago I’ve described the issues that I’ve had since a new version of Read It Later, named Pocket, was introduced.I’ve waited with hope for a new upgrade, but I had a huge disappointment with the latest version 16 June 2012. It didn’t fixed any of the two major problems, that I  experienced since new Pocket was introduced- orums can be referred on  http://www.instapaper.com/main/support page, i.e.http://webapps.stackexchange.com/search?q=Instapaper  or http://apple.stackexchange.com/search?q=Instapaper 5. Tags are more convenient than folders. i.e. an ability for the same article to have more than one tag. Also creating of new folders is not supported offline, which is an annoying limitation.6. I would like to have a narrow list - additionally to existing list modes have a subject only list or subject+site list to show more list items on a screen.7. Limit of 500 offline articles sounds quite big, but my RIL list exceeded 1000, so it could be a issue in the future.8. Search button on iPad version is visible, but doesn’t work- it forces to buy Premium subscription. I think, that it’s not correct. If the button in a paid version is visible and enabled, it should  provide  a working functionality, e.g. search in article names only. And leave full-text search for the premium support.9..Copy URL is an important operation and deserves to be in a first level of Action menu, rather than in Share sub-menu.I’ve also have comment re post http://www.marco.org/2011/04/28/removed-instapaper-free. Marco Arment  explained, why he doesn’t provide free version of Instapaper.  I believe that he is loosing essential part of his customers. When I decided which of iPad application to choose, I’ve selected RIL, because I was able to play with free version, and I liked it. I didn’t have a chance to compare RIL and InstAPaper on iPad, so I’ve bought  RIL pro. For a user there is no point to pay even $3 , if there are similar free product, that user can try and see, is it suitable for him/her.I’ve also played with Readability. It doesn’t have folders or tags(which is very important for me), but nicely supports full text search

  • Switch from encrypted partition to unencrypted (Error: cryptsetup: evms_activate is not available)

    - by Chris Lercher
    I initially installed Ubuntu 11.04 with an encrypted file system (from the alternate install CD: Guided Partitioning, LVM encrypted). Now I wanted to change this setup to have my root file system on an unencrypted partition. I had the following setup before: /dev/mapper/my-root on / type ext4 (rw,noatime,errors=remount-ro,commit=0,commit=0) /dev/sda1 on /boot type ext2 (rw,noatime) I backed up /, reformatted /dev/sda5 (which had contained the encrypted LVM device) to an ext3 partition, and restored / to that partition. I edited /etc/fstab, removed the line /dev/mapper/my-root / ..., and added the line: /dev/sda5 / ext3 noatime,rw,errors=remount-ro,commit=0 0 1 I edited /etc/crypttab, and commented out the single entry. On reboot, I get the grub screen as usual, but then I get the message cryptsetup:evms_activate is not available, waiting for encrypted source device. I tried reinstalling Grub2 using a LiveCD with the ChRoot method, but that didn't make any difference. Why is Ubuntu still searching for an encrypted device?

  • Printing with Lacie Lightscribe requires root privileges

    - by James
    I have installed Lacie Lightscribe software on Ubuntu 12.04. Everything seems to be fine, the drive is detected, the proper media is detected, but when I click print I get the message "Printing Requires Root Privileges". I am the main (administrator) account on this computer, part of the sudo group and I cannot seem to find an answer to this dilemna in plain english. I've seen some apparently relevant posts which say things like "check whether the files /usr/4L/4L-gui and /usr/4L/4L-cli have any setuid-bits set. If so, remove them" but I need more detailed step-by-step instructions than that, please. Is there anyone who knows how to solve this?

  • What ever happened to the Google AJAX Search API

    - by John
    I am looking to query the main Google search however all references including stackoveflow point to the Google AJAX Search API. The odd thing is that it does not seem to exist any more not even a note to say it is depreciated? The old links point to main Google code site. If I look at the list of API's on that site the API it replaced is there Web Search API (Deprecated) which links back to same page but not the Google AJAX Search API. Further Google searching is not being helpful either, many blog posts pointing to the same Google site (http://code.google.com/apis/ajaxsearch/) that has no content and redirects to the same place? Just to prove it did exist I have found it on the way back machine however the last snapshot did not show any special unusual message.

The system has kernel support for UDF installed, I can mount above ISO (mount -o loop) and see its content read only. Any idea how to fix it? Using other than isomaster tool is also an option.

  • Send SMS text messages for FREE using Java ME

    - by hinkmond
    Here's a way to get around those nasty SMS text messages charges (and maybe a way to get around the Pakistan SMS text censors too!). Use this Java ME SMS text app for your Java ME mobile phone, called JaxtrSMS: See: JaxtrSMS free Java ME SMS Here's a quote: JaxtrSMS lets you send FREE SMS and txt messages to any mobile phone in the world. Best of all, the receiver does not have to have the JaxtrSMS app. International and local SMS/texting can be expensive but with JaxtrSMS you can text anyone in the world for FREE! Great! Now, you can send 2,000 text messages from your phone every month and not worry about a huge bill. You don't send 2,000 text message in a month? Well, get it for your teenage kids then. They certainly send 2,000 text messages in a month... Hinkmond

  • In a SSL web application, what would be the vulnerabilities of using session based authentication?

    - by Thomas C. G. de Vilhena
    I'm not sure the term even exists, so let me explain what I mean by "session based authentication" through some pseudo-code: void PerformLogin(string userName, string password) { if(AreValidCredentials(userName, password)) { Session.Set("IsAuthenticated", true); } else { Message.Show("Invalid credentials!"); } } So the above method simply verifies the provided credentials are valid and then sets a session flag to indicate that the session user is authenticated. Under plain HTTP that is obviously unsafe, because anyone could hijack the session cookie/querystring and breach security. However, under HTTPS the session cookie/querystring is protected because client-server communication is encrypted, so I believe this authentication approach would be safe, wouldn't it? I'm asking this because I want to know how authentication tickets can improve web applications security. Thanks in advance!

  • Google Bot trying to access my web app's sitemap

    - by geekrutherford
    Interesting find today...   I was perusing the event log on our web server today for any unexpected ASP.NET exceptions/errors. Found the following:   Exception information: Exception type: HttpException Exception message: Path '/builder/builder.sitemap' is forbidden. Request information: Request URL: https://www.bondwave.com:443/builder/builder.sitemap Request path: /builder/builder.sitemap User host address: 66.249.71.247 User: Is authenticated: False Authentication Type: Thread account name: NT AUTHORITY\NETWORK SERVICE   At first I thought this was maybe an attempt by a hacker to mess with the sitemap. Using a handy web site (www.network-tools.com) I did a lookup on the IP address and found it was a Google bot trying to crawl the application. In this case, I would expect an exception or 403 since the site requires authentication anyway.

  • building kernel headers (v3.4) breaks wifi (in Ubuntu 12.04.1 LTS)

    - by iphonedev7
    I have dual-booted by Samsung Series 5 Chromebook into Ubuntu using Jay Lee's script/instructions, and then installed the ~500 updates that appear thereafter. Now, I am trying to build my kernel headers in an attempt to enable virtualization so that I can run VirtualBox (I have a VM image on a flashdrive). I followed the instructions here: https://groups.google.com/forum/?fromgroups=#!topic/chromebook-central/PPQFpC7mYzk mainly doing as olofj suggests in his answer, while also making sure to abide by additions/edits made by panZ and algp. However, now that I have done so, my wifi has stopped working, and when I click on the network icon in the top bar, in place of wifi networks there is a grayed-out message that says "no network devices available". I have an Atheros AR9300 Ethernet card (I think thats what you call it). Any help is much needed and appreciated. Any further details necessary to answer the question will be provided as necessary. Thanks!
