[[!meta title="Project Ideas"]] A lot of what SIPB does which is not helping users with immediate problems and answering questions falls under the heading of SIPB projects. SIPB projects are usually things that a member or two have decided are worth doing and are working on. The main qualification of SIPB projects is that they help the MIT community or the world at large in some way. In general they also involve computers. Here's a list of SIPB project ideas that have been mentioned recently, along with the person who's suggested the project or a team that would be good to contact. Feel free to get in touch if something sounds interesting or you want advice getting started. A [[list from 2008-2009|/doc/project-ideas]] may also have some relevant ideas. [[!toc]] ## "add me to this list" button If I'm a webmaster for some group with an announcement list, it would be really nifty if I could add some HTML code to my page to create a button that, if someone clicks it, would use MIT certificates to find their username and automatically add them to a list. This isn't particularly difficult; you'll need to get a keytab (essentially, an account in Kerberos / Moira) for the website, and write a script to set that keytab as the list's "membership ACL" and a webapp to use that capability to add or remove people from the list. _Contact: geofft_ ## debdiffs of Debathena packages We have [a webpage](http://debathena.mit.edu/package-list/proposed) to list all Debathena packages in the ["proposed" repository](http://debathena.mit.edu/experimental#proposed), i.e., things we just changed and are waiting a few days for testing before pushing to the clusters, etc. However, that page gives you no information on what the change was. A very useful addition would be to use the `debdiff` tool to link to the changelog and code changes for each new package. _Contact: broder, debathena_ ## Better Trac-email integration A bunch of SIPB projects use [Trac](http://trac.edgewall.org/) as a bug tracker. The current email adapter we use [isn't very clever](http://debathena.mit.edu/trac/ticket/308); it'll send out each update to a ticket with a generic subject line, so it doesn't easily indicate whether the bug was resolved or someone just commented on it. It also doesn't know how to receive e-mail, so we can't reply to the e-mails it generates and have our comments go back into the bug tracker, and we can't [make bugs@mit.edu create Trac tickets](http://debathena.mit.edu/trac/ticket/216). There are one or two alleged plugins to do this, but they create a new ticket on every e-mail, rather than doing something intelligent with replies; a better plugin in both directions would be extremely helpful. _Contact: debathena, geofft, broder_ ## PulseAudio support for the office sound system There's a server in the SIPB office that you can "print" MP3 files to, and they will get played one by one. A significantly more modern interface to this would be to make a [PulseAudio](http://www.pulseaudio.org/wiki/AboutPulseAudio) server out of the computer hooked up to our sound system; this lets computers running PulseAudio (notably, most recent desktop Linux distributions, but Windows computers that install Pulse as well) route their sound to the office speakers. _Contact: geofft_ ## Cluster and printer viewer for the iPhone You might have seen the xcluster displays (in the SIPB office, near the four building 11 quickstations, and in the building 12 cluster) that show you which clusters aren't in use and which printers aren't hosed. This would be immensely more useful as an iPhone application. _Contact: ccpost_ ## Snapshotted virtual machines for all popular Linux distributions A common need for people writing Linux software is to check that their software works on many popular distributions (Red Hat, SuSE, Debian, Ubuntu, Xandros, etc. etc.), and on multiple versions of these distributions. The qemu system emulator, and its virtualization cousin kvm, support image snapshots and a fairly lightweight process for running virtual machines, so you could set up an Athena locker with a few commands that give you a temporary copy of a Linux system for a particular distro and version that runs inside your terminal. _Contact: geofft_ ## Efficient disk snapshot support The previous project and a lot of other work could be made significantly more efficient by rethinking the design decisions in qemu's snapshot support. If this is the kind of thing that interests you... _Contact: nelhage_ ## SIPB PostgreSQL server A lot of people prefer Postgres to MySQL, so having a community Postgres server akin to [sql.mit.edu](http://sql.mit.edu/), with similar access control, could be a useful project. You could set it up on [XVM](http://xvm.mit.edu/) with an eye to redoing the configuration on a scripts-hosted VM at some future point. This could easily become a bigger project, integrated with scripts' autoinstallers, etc., depending on ambition. Or it can just be a standalone server for people who want access to a Postgres database, but don't want to set up and maintain a server on their own. _Contact: mitchb, geofft_ ## Rewriting "add", "attach", etc. for Debathena Athena used to have a system _liblocker_ for managing the /mit directories and attaching and detaching links to networked filesystems. Debathena and Macathena come with an automounter for /mit, so links automatically appear when you use them, and nobdy cares much about detaching them, but we still use most of the complexity of liblocker because we haven't gotten around to cleaning it up. There's a [design proposal](http://debathena.mit.edu/trac/wiki/FixingLiblocker) on the Debathena bug tracker listing what should be a better implementation. _Contact: broder, debathena_ ## Checking scripts.mit.edu servers for consistency Now that we have five or six web servers (I've lost count), it's become entirely too easy to change something on one or some but not all of the servers. We often test changes, like newer versions of packages or tweaked configuration, in place on one of the servers, but we'd like something to remind us if we don't copy these changes to all the other servers. This involves checking packages (RPM, perl, etc.) as well as config files in /etc and possibly other things like LDAP config. I've also been told by multiple people that [Puppet](http://reductivelabs.com/products/puppet) or some other configuration mangement framework is the Right Answer here. We looked at Puppet and a bunch of others last summer and concluded none fit our workflow well, but we could re-evaluate that. _Contact: geofft, scripts-team_ We'd like a cron job to automatically tell us if there are RPM packages installed on some but not all of the servers, or if there are changes in /etc, other than hostname and such, that we haven't committed to the scripts Subversion repository. ## SIPB Library SIPB has a bunch of books in its library. It'd be nice if a list of the library books also existed online in some sort of sane, searchable database. One possible platform is the [Exhibit](http://simile-widgets.org/exhibit/) project (which originates from a collaboration between the Haystack group in CSAIL and the MIT Libraries). This would require mostly just making a spreadsheet of the information. _Contact: pbaranay, fawkes_ ## Improve the Setup and UI for new users of Zephyr Currently, it is a pain to get someone else set up using zephyr within screen on Linerva with automatically-renewing tickets. We should write scripts to set them up so that that all they have to do is enter a command or click an icon, type their kerberos password, and then know how to use Barnowl. _Contact: afarrell_ ## MITeX Not a fully formed thought, yet, but the basic idea is to have a web app that lets users create a document, and then it texs the document nicely for them, based on some template that they've selected, and gives them a PDF. They should have the ability to edit the source or just use the WYSIWYG editor. _Contact: jhamrick_ ## Build a web client providing full control to the user Create a web browser extension (or possibly a stand-alone browser) that is "web-developer antagonistic". It essentially takes full advantage of the immense power of a web client, ignoring the wishes of the web developer and server while letting the user take full control. Every JavaScript event (ideally variable, function, etc.), every rendering decision, every cookie setting, every HTTP request, if the user so desires, etc. is not only made visible but easily changeable. When making a request, every aspect of the transaction can be completely fiddled with. There are several extensions that allow you to do stuff sort of like this (Firebug, Web Developer Toolbar, Chrome's web developer tools). But they're hard to use and really mostly just debuggers. Our goal here is to build something that goes out of its way to give you complete control via a nice UI. _Contact: leonidg_ ## Improve git with shared checkouts Around SIPB we're kind of [big](http://sipb.mit.edu/iap/git/) [fans](http://web.mit.edu/cluedumps/slides/understanding-git-2008.pdf) [of](http://blog.nelhage.com/2010/01/on-git-and-usability/) [git](http://negativespace.mit.edu/2010/03/08/gitionary-the-graphical-game-of-git-guessing/). But there is an area that git comes up short. We have a lot of common directories where people really just want to edit files in place (instead of wanting to clone/checkout, edit, commit, push...), but git doesn't support that well. It would be cool if there was a way to work with non-bare repositories in shared directories. One idea might be using FUSE to present a separate checkout to each person using the directory. _Contact: broder_ ## Scripts Pony Improvements [Scripts Pony](http://pony.scripts.mit.edu) is scripts.mit.edu's new hostname management system. It was just released recently, and has lots of bite-sized improvements remaining to be implemented. Particularly good ideas include adding the ability to show and edit hostname aliases, checking whether hostname paths exist and giving appropriate feedback, creating a zephyrbot to allow people to approve tickets easily, and adding the ability to check hostnames in Moira automatically. See [the project TODO file](http://web.mit.edu/pony/TODO) for more ideas. _Contact: xavid_ ## Bazki [Bazki](http://bazki.mit.edu/) is a wiki written in Python designed around several principles: structured data with object-oriented inheritance; using a wiki language with powerful macros that can be compiled into either HTML or PDF (via LaTeX); and making the content editable offline using a VCS. Bazki works enough to to be useful, but it has lots of room for improvement and probably would benefit from some design changes. It could also definitely use documentation. _Contact: xavid_ ## A zephyr log viewer Many SIPB-affiliated people use the [Zephyr](http://zephyr.1ts.org/) messaging system, and the [Barnowl](http://barnowl.mit.edu/) client for it in particular. Barnowl has a number of very nice features that make it easy to follow large amounts of zephyr traffic: search, color coding, auto-narrowing, etc. Barnowl can also store logs of zephyrs sent and received for future reference, but the logs are saved separated by class in a way that's quite annoying to navigate sometimes. A Barnowl-like interface (perhaps implemented as a Barnowl plugin) for viewing zephyr logs would be a great thing to have. _Contact: oremanj_ ## Migrate Gutenbach from lprng to CUPS lprng is the past, and CUPS is the future! Our music player, Gutenbach, is currently running on lprng. With the rest of campus switching to CUPS, it's really time we did so as well. The filter needs to be rewritten for CUPS (and preferably in Python, this time), and the package needs to be redesigned to handle the way CUPS does things. _Contact: jhamrick_ ## Your Project Here SIPB can help you out in terms of both computing resources and experienced people to bounce ideas off of. If you've got an idea for something cool to advance the state of computing at MIT or just computing in general, [[drop by our office|office]] and say hello.
