Just a collection of things that might be worth implementing. Maybe giving someone ideas :)
facebook/google+ in an encrypted, decentralized way
With prism users would like to have the broadcast capabilities of facebook (conveniently post to a group of people), while having the option to stay anonymous for others than the recipients, and to encrypt the broadcast so only the recipients can read it. Writing an email to recipients and encryping with the recipients pubkeys works, but is not as convinient. diaspora is an approach into a decentralized direction atleast, and doing this in an open way. Maybe just a graphical frontend for mail+gpg is a good start.
scripting OpenStack deployment with nested KVM
Nested KVM allows to run virtual machines in other virtual machines. Testing things like OpenStack gets easier: create an image, and inside several virtual machines with the OpenStack components.
auto-manuscripts for puppet
puppet implements manifests on client systems. This workstyle means a paradigm change for sysadmins. How about this: * a new system gets deployed * a script looks at it * the sysadmin does his changes live on the system (change files, install packages) * a script looks then again at the system and implements the manuscript itself
graphical shared-memory picture
http://virtualthreads.blogspot.com/2006/02/understanding-memory-usage-on-linux.html describes how to see what memory/libs are used/among what processes. This could be presented nicely graphically, imagine a bubble 'libz.so' and seeing what processes use it..
cobbler/anything instructions file
There are kickstart-files for redhat* distros handing out informations how to setup a linuxbox. Suse does a similiar thing with autoyast, the file using a completely different syntax thou, and admin unfriendly xml format. Ubuntu uses preseed-file, containing simply the selections that are made in the installer, debian/fai uses a more complex format with a directory-structure mounted and avaluated. There coule be one ontop-standard describing a partitioning, what users to be created etc. and optional parts ontop that get only nonoured at the distro. Such a default-setupdescription could also serve for bsd, solaris deployments.
xing/openbc in an open way
This network hosts data of people and interconnects it, you have to pay to see who is looking you up. Such funktionality could be provided in an open way. People should host their profiles on a website and interconnect to other people in linking to their profiles - located on other URLs on the internet. Lookup semantic web. A network would span over the URLs. And my data would also be hosted by me, thats what i want. Ofcourse people would also be able to host their data without own servers, there would be providers for this, also free ones, as for openid now. The idea settled reading a thead at the tlug.jp mailinglist archived here: http://www.tlug.jp/ML/0809/msg00082.html .
Update: there are now at least APIs like http://code.google.com/apis/opensocial/ to communicate such informations across borders of webapplications like xing and linkedin.
appliance-like networkboot from cd-isos
gpxe http://etherboot.org now allows more flexible pxe-booting, i.e. one can fetch linux-kernels via http. There are services like http://boot.kernel.org/ publicly offering distros ready to get booted. Next step would be to directly boot a iso9660-cd-image around on some ftp-server on the intranet! The single parts are around; ftp-files can partly be read, also be mounted as filesystem. iso9660 can be accessed there blockwise for getting first blocks for the boot, thats just required in gpxe. With this new live-cds could be tried out onthefly over the internet.
universe-emulator for slack
Slack ( http://www.sundell.net/~alan/projects/slack/ ) is a small and nice distribution-system for configs and software, sysadmin-style. The author states in slack-intro:
I haven't invented the parallel universe simulator yet to see how the world will react to the actions of your scripts
Actually.. implementing this could be fun. Either making a copy of the whole system in a subtree with rsync and then running scripts chrooted on that (escaping daemon-restarts etc, as those would influence the real system) or virtualizing the whole system and running the script on that. After that diff'ing i.e. all files and report what was changed.
There is Second Life, kind of muds, kind of how people use world of warcraft. Maybe its a different more intuitive way to present some media and bring people together. But some points could be improved:
- Noone should own it. ThirdLife should be a cyberspace where noone owns the infrastructure
- everone should be able to run own parts of this virtual world (as with homepages nowadays), it should then be reachable for everyone else (as webpages)
communication-hub of the future
Recently visiting an old fellow at a research centre at Garching i saw they use video-chat on a daily basis. Also for things where i would simply prefer instant messaging. There are many things, all provided by one single app:
- I want a roaster with presence notification, messaging to other people (like jabber provides)
- Ability to use groupchats (like MUC-chat in jabber, or IRC)
- Ability to share screen with other people (like vnc)
- Sharing of whiteboards with other people (coccinella implements this for jabber)
- voice over ip and video phone (jabbin implements this for jabber)
- beeing able to really simple establish network-connections (like hamachi does)
- using this on the internet, vs. using it in restricted intranets. maybe securely connecting both in one app on work-desktop.
- beeing able to use all this as plugins with a single application, would make the perfect media-hub.
hamachi-like jabber xep (extension)
Hamachi provides an instant messenger, users can establish vpns connecting each other. Thats a great idea, just that hamachi isnt free but proprietary. Why has noone yet suggested a jap to implement this into jabber? Maybe using openvpn as backend?

- This could be automated, detecting the hardware of a computer, searching the net for appropriate pictures, modifying the picture, creating the wallpaper&conky-config.
