Like I said, the we-page I quoted is well out of date. I think all the latest iPods are well supported by Amarok, Banshee and Rhythmbox. I'm pleased to hear that the Ubuntu One store is really good. I can see the time when Apple regrets the decision not to build iTunes for us! The other examples you quote are fairly typical of the experiences most of us have with Windows users. I'm surprised you had difficulty sourcing an IDE drive - there are seven pages of them currently on e-bay. Also, you can buy very cheaply an ide to sata adaptor. If your father in law has a desktop, I'd get him a sata drive and one of those little sata/ide adaptors. I got mine on e-bay. Thanks for sharing your news.

[ubuntu-uk] Research required ...
Ubuntu One store has enough music to buy things. I have found that the latest Album by Blunt is cheaper than iTunes and amazon. I thought amarok and banshee had support to put music inside the ipod? Recently I installed ubuntu on a girl's laptop that I haddn't even met face to face. She had XP and was going slow because of antivirus it seems. She only uses it for facebook and email so she seems to be happy with what she had: only problem I had was that I fogot to tell her the keyring password. Also had a problem with father in law: HDD broke windows wasn't loggin it. It was an IDE HDD so not something you can easyliy find it seems. He was content with waiting a while longer and booting from an Xubuntu live CD. It's only used for browsing. Sister in law had a netbook with xp it crashed. Her other brother in law was unable to install a dodgy copy of windows but I was able to install no problem ubuntu netbook10.10. Even hung over from newyears party she knew that firefox icon was internet and that she could do her documents with openoffice. I told her I could provide with remote support (I can right?) and she was well happy that I could recover her 16Gb of pictures. I tried explaining gwibber but was not convinced. Chat with facebook (empathy) failed but that happens to me as well.. quote: Message: 1 Date: Mon, 27 Dec 2010 12:06:18 + From: Barry Drake Subject: [ubuntu-uk] Research required ...

Ashton and I have been trying to research easy entry into Ubuntu with the mindset of the average Windows user. Please consider helping with this research. The aim is to pick a particular 'need' and to follow through whether this need can be met under Ubuntu, how easily and how successfully. This use should ideally be one that your Windows friend would have, and preferably a need that you know little about. First take a look at: https://help.ubuntu.com/10.04/switching/C/applications-equivalents.html This page may need revision, and certainly needs extending. Rules for research: any necessary packages to be easily and quickly installed without using the commandline. The preference would be to use the Ubuntu Software Centre. If you have a way of meeting the need, but this requires commandline or other methods, please submit this anyway - Ubuntu could incorporate a simple workaround. Any scripts or code you write to make things work could be posted. Stuff like that could easily be part of a package and run on installation without the user being in any way aware of the complexity. When you have done the research, please report on how easy it was to access the information and provide links if a good method is suggested online somewhere. So far, I have researched iPod and iTunes. I have also explored Logos/Libronix as a colleague has over ?1000 worth of books in that format. I have to report that Ubuntu is not for him. I have e-mailed Logos and received a reply stating that at present they do not have plans to support our platform. The same was true of Mac until many many Mac users complained to Logos! A niche area, but maybe you'd like to aid that cause? I also did a webcam exercise with my sister. The task was dead easy for me - but incredibly daunting for my sister and it need not have been! That one hardly wants any tweaking but it does need tweaking and properly documenting. Researching iTunes, I found an official Ubuntu document that said iTunes would install under PlayOnLinux. I tested this. Only iTunes 10.6 can be made to work, and it installs crippled. The CD rip and burn facilities don't work. It is official policy that we do not include methods based on Wine or any of its derivatives as these, however good, are not for the Ubuntu newbie. The result of the above is that iTunes can be perfectly replaced and iPods work just fine under Ubuntu with several apps BUT the Apple download store cannot be accessed. Most of you knew that already - I was working in the dark and discovered how hard it was to get information that a newbie could follow. So - lay aside your geekiness for a time, imagine you're a newbie and volunteer to research a particular need. Please state the one you are thinking of pursuing so we don't duplicate the effort. If there's a good response, maybe someone who has admin access to the Canonical or Ubuntu website can set up a Wiki for us to report back on? Hope I'm not treading on any Canonical toes here apologies in advance if I am.

Sirius is looking for a qualified individual to work as a Technical Support Engineer. The Support Engineer provides comprehensive telephone/web/e-mail/chat technical and application support to Sirius customers. The candidate must be able to work directly with customers in high-pressure situations; have strong analytic, organizational, time management, and communication skills; thrive in a team environment; and possess the willingness to do whatever it takes to achieve the highest customer satisfaction. The candidate will interact with development and project teams to investigate and resolve issues. The job responsibilities include, but are not limited to, analyze, track and resolve customer issues in a professional, timely manner; identify any security upgrades that are necessary and communicate them to customers; maintain and update web based support documentation, using monitoring software to identify potential support issues. The role is shift based and will include some night shifts. Requirements * Experience working with Open Source technologies * Excellent verbal and written communication skills * Outstanding interpersonal and telephone skills * Strong problem solving skills * Ability to function and thrive in a team environment * Energetic, with a strong desire to succeed * Experience within a similar role would be beneficial If youre interested or want to know more about the place or the job you can contact me on freenode as czajkowski or mail Kelly - kelly DOT flitter @ siriusit.co.uk to talk more -- http://www.lczajkowski.com http://wiki.ubuntu.com/czajkowski skype: lauraczajkowski Message sent using UebiMiau 2.7.10 -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
Re: [ubuntu-uk] Research Required
Rather than the football analogy I use the recipie analogy (I think I heard Stallman use it). If you are a good cook and you make your soup for free at home to your friends and/or give the recipie so others can improve on it will it mean that it will be worst than at a michellin star soup. There is a good chance that it will be better since you can adjust it as you like and it has quicker feedback. You can then charge on support to make sure your reciepie works properly on your kitchen so you don't need a new induction kitchen to get the same result. Was planning on writting something on the recipie of a spanish omlette, similar to the lines above. -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

It's a cute metaphor, but inappropriate. Encryption doesn't lock a room, it changes the entire contents of the room into other, random atoms. There's no keyhole, no tumblers, nothing to see at all except nearly-random noise. We are very unlikely to see a genuine weakness in AES-256 in the immediate future.

What you can't see is any of the tumblers *in* the keyhole, or through the keyhole to what is behind it, as that would be a security failure. If you could get even a glimpse of either the make-up of the keyhole or the contents that it is protecting, then you now have sufficient plaintext or key leakage to start reducing the brute-force case into something more practical.
