International Space Apps Challenge

On the 21st to 22nd of April, TOG will host the Dublin base for the International Space Apps Challenge.

The International Space Apps Challenge is a two day event that will be taking place all over the world and off world (on the International Space Station). The event is aimed at solving global problems through collaboration both at the local and international level.

There are four main categories of challenges: software, open hardware, citizen science, and data visualisation. You can collaborate on one of the listed challenges or you can propose your own challenge for people to collaborate on.

You can register to take part in the event at http://spaceappschallenge.org/location/tog. TOG will be open for the duration of the event, and if you have any questions, please post a comment.

Note: This a free two day (or overnight) event. Please only register if you can attend both days as the number of places are limited. You can also register if you can only make one day or part of the day.

The plan is to start at 12:00 (noon) on Saturday. We are collecting useful information about our activities here

Intro to Mailing Lists

I’m sure you’ve come across mailing lists before; a service to which you subscribe, and when someone posts to the list you get the email. TOG has a public mailing list, that strictly speaking operates as a discussion list. Anyone subscribed can post to the list, on-topic discussion is encouraged, and you will get more than just anouncements.

The Mailman GNU logoTo join our mailing list simply go to http://lists.tog.ie/mailman/listinfo/tog, enter your email address, and press the “Subscribe” button. A confirmation email will be sent to the address you entered, to which you can either reply, or click the link included. You will then receive a Welcome email, with info like links for subscription info, passwords, etc. It’s a good idea to keep this email around.

Perhaps the only real choice you need to make is whether or not you would like to receive list mail in daily digest format.
Pro; seperate emails will be bundled together and sent as one mail, therefore you will have less emails in your inbox.
Con; seperate emails will be bundled together and sent as one mail, meaning you might not see the discussion until after it’s over, and you will have difficulty replying to individual emails (quite a bit copy-pasting is involved).

If you plan to lurk and only ever read, and don’t mind being a bit behind the times, then digest-mode might be for you. For everyone else we recommend selecting “No” when asked if you’d like to receive the daily digest. It will make your life a lot easier, promise.

There are other tricks and techniques to making surviving a mailing-list easier, but many come down to your actual mail-client itself. For instance, if offered, use labels, filters, folders, anything to sort the mail automatically without you having to do anything. That way you can leave the mail sitting in your inbox (or other folder) until you’re ready to deal with it.

And remember, the tog public mailing list is archived. To browse the archives go to http://lists.tog.ie/pipermail/tog/, and browse month-by-month, sorted by Thread, Subject, Author, or Date. If browsing isn’t for you and you’d like to search the archives, it’s time to employ some google-fu;

Go to www.google.ie and enter;
site:lists.tog.ie inurl:/pipermail/tog/ WHATYOUWANTTOSEARCHFORHERE
e.g. to search for “open social”, then do a google search for
site:lists.tog.ie inurl:/pipermail/tog/ open social

There you go, that should be enough to get you started! Just one other thing; don’t forget your manners, and try to follow good netiquette.

Welcome to the mailing list.

(And remember, you can always unsubscribe! Bottom of page here. A few simple clicks can take the pain away 🙂

4 Month Pinhole Photo

In Nov 2011 we left a pinhole camera taped to the drain pipe in TOG’s yard looking south. So its been up for 4 months. It’s just a beer can with a 1mm hole and a piece of b+w photo paper inside. We took it down today and scanned it in. The raw image is upside down and back to front. The “colours” are also inverted. You can see the track of the sun and how it gets higher in the sky, as the days get longer.  The gaps are days where there was no sun. After a bit of trickery in GIMP, its right way around and inverted. We have lots of photo paper in TOG if you want to come in and make one. You can leave it in place from days to months and still get a good image. Click on the images for a closer view.
