Are you a (student, grad-student, post-doc, lecturer, professor, working in the big bad private sector) scientist?

Do you use KDE software?

Do you use KDE software for your science?

If you can answer ‘yes’ to two or more of the above then I would love to hear from you.

Update: Well, actually, I have plenty of answers now Thanks very much. I don’t need any more responses, but if you’d like to let me know what you think then by all means go ahead (probably won’t make the article though).

There are (I sense) a few scientists in KDE land and some of us (Luca and myself at least) are beginning to ponder how we can achieve world domination for KDE through the sciences.

We have some pretty cool sciencey apps already:

• Kile (LaTeX)
• Cantor (young, but promising)
• KBibTeX (I crave a Platform 4 port)
• LabPlot (Platform 4 port in progress)
• Kalzium
• Kalgebra
• KStars
• Marble
• Rocs
• KmPlot
• Step

We also have external projects such as SciDAVis that are working with KDE projects (LabPlot in that case).

So, if you can spare some time for me, here’s a mini open interview for you:
(Edit: made it an ordered list for easier answering and added questions 9 and 10 from Luca)

1. Who are you and what field to you work in? (Add where and for whom if you’re happy to do so)
2. What KDE software do you use in general?
3. What KDE software do you use specifically for science?
4. Were you aware of all the applications I listed above?
5. If not, are there any you weren’t aware of that could be relevant to you?
6. What is missing among KDE software for you?
7. Would you be interested in a dedicated mailing list/website area for KDE software for scientists?
8. What else would you like to tell me?
9. If you developed scientific software/algorithms, did you ever consider KDE users/platform as a target? If not, why?
10. Did KDE software help you with your research in general? For example, do Kontact or Plasma widgets help keep things orrganised?

I’d like to make you comments up in to some kind of Dot article – they may be edited and it is likely that not everything will be used. You can either drop a comment using the form here or mail me directly at myfirstname.mylastname at gmail.com (if that isn’t obvious then go to the about page and solve a captcha to reveal my email address). If you use the comment form then please use your genuine email address (it is never disclosed) if you’d be willing for me to come back with some follow-up questions.

Also, if you’re making it to Akademy, there are at least a couple of KDE-science things that you can attend: Luca’s BoF at 1500 on Tuesday (see the wiki page) and my lightning talk at 1030 on Sunday.

A while ago I asked “what’s stopping you from joining KDE?”. It was really a rhetorical question but, thinking about it, it is something I’d be interested to hear answers to.

There’s an interesting blog post (thanks to Lydia for sharing this on Identica) that points to some possible reasons. It seems the top ones are:

1. Not enough time
2. Not sure where or how to contribute
3. I’m not confident enough in my own skills

What stopped me?

Thinking back, there were a few things that delayed my own involvement with KDE. Time was a big one: I didn’t want to be that guy who turns up, makes some suggestions and promises but never delivers, so I waited for when I might have more time. I knew where I would start (Dot articles) but there was a bit of a lack of confidence in my own knowledge too – that I’d get found out writing about stuff I don’t understand as well as all you guys. I still get that , but hopefully it just makes me do my research a bit better

There is never a good time

Eventually, I realised that I will probably be busy for the rest of my working life. Actually I realise now that I had far more time when I thought I was too busy than I have now. The result is that I am that guy who turns up, makes suggestions and promises to do things but doesn’t deliver Most of us are. But the thing I realise now is that a lot of people doing some of the things that need doing some of the time can achieve quite a lot. It really is better to light a candle than to curse the darkness.

You don’t know enough, but then – who does?

When you start contributing, you’ll likely realise you don’t really know what you’re doing and chances are you will screw up (but people are nice about that, generally). But you will be bringing in some skills that others don’t have. Perhaps you’re a native speaker of a language we need to use for a press release (so you can instinctively see when something doesn’t sound quite right) or you have language skills that allow you to translate useful information or act as a bridge to KDE communities around the world. Perhaps you have useful contacts in education, among artists or in science that allow you to put (potential) users in touch with developers.

Start where you want to start

The possibilities for contributing to KDE are vast. Jos (and us other promo peeps) would like your help, but there are plenty of other options too. There can be few application teams that wouldn’t welcome more developers and we always need artists. Whatever you want to do, you can get involved.

So, why not contribute?

If you would like to help out, but there is something holding you back then why not tell us? We need people and if there are things we can do better to make contributing easier it would be great to know.

Hello KDE fans, I have a couple of tasks for you:

Design KDE swag

KDE has a new spreadshirt store with a couple of nice t-shirts by Sebas and some badges including some work by Ingo.

We’ve been formulating some ideas and designs on the wiki and some, like mine, are in need of some proper artistic input. There are also several ideas that haven’t been developed into draft images yet.

So, what’s in it for you? Well, you get to say you contributed to KDE and might get to see your creation wandering around Akademy, plus there is talk of giving the designers a free copy of the t-shirt, or whatever, containing their design.

Here’s some additional info courtesy of Justin on the kde-promo mailing list:

1. We do have some existing logos and things you may want to use or at least be aware of which are stored on the Community wiki. Logos are in the KDE clipart link at the top.
2. Spreadshirt allows for both “vector” and “pixel” designs but due to the nature of of the t-shirt medium it is highly advisable to design in a program that produces the vector graphics so we can scale them as needed without distorting your images. Though I think in some cases if we only have “pixel” versions we might be able to work with it if the resolution is high enough.
3. Since this is printed media you should design everything in CMYK colorschemes rather than RGB.
4. More details about the Spreadshirt “design” uploading process can be found on the Spreadshirt site
5. “Be Creative”…”Be Inspired”….”Be Free”

Provide your science photos for LabPlot

Something I started working on a number of months ago and have recently come back to is working on a website redesign for LabPlot.

The current draft is at lp.asinen.org (there’s still a lot to do, integration of the logo in the header definitely needs a lot of work). One of the things I want to have is a rotating image in the sidebar. I have a few already – one is displayed and the rotator is implemented but I’ve lost the copyright info for the others so only displaying one at present. It would be great to get photos from actual KDE people in Science – I’m after things that are fairly simple, optionally quite abstract from any branch of science. You should be prepared to license the image under Creative Commons Attribution Share Alike (or something more liberal). You can send images to me at stua…@gmail.com (click on the dots to solve the CAPTCHA) or just put a link to an online image in the comments. Please specify the license and make it clear that you’re the copyright holder in your comment or email.

Dear lazyweb…

My operating system hard disk has failed (again – kinda, poking it from a live CD shows that the filesystem isn’t recognised, though I can mount it if I explicitly state it is ext4 and a fair bit of the data is still there). It’s a vintage 70GB Seagate, the SMART diagnostics are not good, it has got corrupted before and I didn’t really trust it anyway – data is on another disk.

So, it’s time for a new disk.

The question is whether to buy another spinning disk or go for solid state? Does anyone have experience of an SSD and have a view on advantages/disadvantages (I’ve Googled a bit already). I’d be going for a cheap MLC SSD at probably 30-60GB (Intel or OCZ) which is plenty for the OS and .kde etc – i.e. stuff with little files and lots of seeks, most of my data would stay on the other magnetic disk. Alternatively I’ll get the smallest magnetic disk I can find. The SSD option is likely 50-100% more expensive.

I also need to decide what distro to put on the new disk. The old system was Fedora 12 and I’m pretty happy with that, but I always have a bit of a look around when I’m doing a new install. I have a laptop on F12 too and my work PC runs F11, while a geriatric Shuttle PC acting as a media centre runs Arch.

I’m looking for a distro that:

• Packages the latest KDE SC (and does it well)
• Installs only free software by default, including drivers
• Has good repos for multimedia stuff, if not included – 3rd party is fine
• Isn’t obsessed with re-inventing the wheel (use NM, one of the major package managers/PackageKit – or have a good reason for not doing so)

Bonus points for working well with upstreams and contributing to KDE. Good (free) Radeon drivers are also a plus. I’ve recently played with Kubuntu and Mandriva in VirtualBox and not been convinced they’d be better, but maybe I missed something?

Any thoughts?

How do we get more people interested in KDE software? We can talk about it being Free (and free), point out that it does everything that the proprietary competition can do (if that’s true) but there is always a cost in changing software: you have to learn new stuff. Therefore our biggest openings are when the alternatives suck and so people are looking for change or when our stuff just leaves the competition for dead. The latter one is about the wow factor – something in our software that makes the casual observer sit up and take notice and think “I want that”.

The wow factor could be visual, but it needn’t be. Here are a few things that have prompted people who see me using KDE software to ask what the application is:

• KWin – the desktop effects are really pretty slick now (this one works best on people who don’t use Macs)
• Konqueror shortcuts – I use the gg shortcut for Google and have set up ‘go’ as the shortcut for Google I’m Feeling lucky (it’s shorter and, to me, more intuitive than ggl). Several people seeing me use ‘go bbc news’ (or whatever) have been pretty much dumbfounded – “you mean you can just tell it where to go without knowing the address?”
• Kopete – “You’ve got all your chat accounts in one app?”
• Amarok – the Wikipedia integration, mainly
• Okular – people love that presentation progress indicator
• KRandR – people are suprised I can just plug a projector in and activate it with a couple of clicks
• Digikam – it’s just so cool all round, but the Facebook upload plugin is a particular winner
• KRunner – it looks fairly funky and people are impressed by the speed of launching applications (most menu launchers suck)
• Marble – fairly cool anyway, but fire up the OpenStreetMap view and people want it
• Kile – simple things like code completion and syntax highlighting impress people trying to use Notepad for LaTeX
• Gwenview – it’s just so shiny, particularly in full-screen mode

Several items in that list surprise me a little, because they’re things I take for granted (Konqueror’s web shortcuts for example) and I’m sure several of them would leave a lot of people cold. So which can we push when promoting KDE software, which can we demonstrate at events and what others can we add to the list?

I’ve started a page to track these on the wiki, so please add your own or comment below.
