Hi All,
I hope everyone has had a good 1st week and settled back in to Oxford life. It was great to see so many people at Freshers' Drinks on Tuesday.
This week we have two events planned, a talk on 'Using Machine Learning To Solve Real-World Problems' on Tuesday and a film screening on Saturday.
Read more below to find out about these events and this weeks technology challenge (which is open to anyone, but only members can win prizes) - as well as last weeks solution.

Using Machine Learning To Solve Real-World Problems:
Tuesday 18, 20.00-22.00 St Catz JCR Lecture Theatre
Link: http://www.facebook.com/event.php?eid=266683403374448
How do you approach a classification problem involving thousands of categories rather than the 'usual' five or six? What happens when your data-set is several gigabytes and growing? What open-source tools are available, are they any good, and can they be put to commercial use? How do you measure the system's effectiveness when you're not allowed to see the real data because of client confidentiality?
David North and Richard Ashby, from local software company CoreFiling, will aim to answer all these questions and more in their talk on machine learning from an industry perspective. There will be free drinks afterwards.
David has for some time been a CompSoc Systems Administration Co-ordinator (http://compsoc.net/network/), if you think you might be interested in taking over this role or just want to know what it is then after the talk would be an excellent opportunity to ask about it.

Technology Competition:
Challenge 2:
This weeks challenge is to determine what the code below does:
def f(b):n=b.find('0');~n or exit(b);[m
in[(n-j)%9*(n/9^j/9)*(n/27^j/27|n%9/3^j%9/3)
or b[j]for j in range(81)]or f(b[:n]+m+b[n+1:])
for m in'%d'%5**18]
Once you have figured it out go to
http://compsoc.dartoxia.com/answer/<ANSWER GOES HERE>.
Anyone (with a .ox.ac.uk email address) can sign up to the competition through the http://compsoc.dartoxia.com website, but only members can receive prizes.
Compsoc.dartoxia.com isn't connected to the compsoc network, and so you will need to make a new account to participate.
For more details about the competition see http://compsoc.net/technology_competition or contact committee(a)ox.compsoc.net
------------------------------------------------------------------------
Technology Competition:
Challenge 1 Result:
Congratulations to Alaric Stephen for solving the first challenge the quickest - we will get in touch separately to arrange your prize.
Last weeks challenge was "What does our logo mean?". The correct answer was OX. This answer is found if you interpret each dot to be a 0 or 1 depending on shade and for the columns into values: 0100 1111 0101 1000 = 4 F 5 8. Now if you look up the ASCII symbols for 4F and 58 you get OX.
------------------------------------------------------------------------
Membership:
Our current membership rates are £5 for life and £3 for a year. Being a member entitles you to free socials, prizes in the technology competition and you can attend (obviously) members only events - such as the upcoming Bank of America dinner. You will also receive a CompSoc membership card!
Hi guys,
Just so you know, we will be watching 2001: a space odyssey on Saturday night.
More details about the event can be found at http://www.facebook.com/event.php?eid=302974333051482.
All the best,
Ben
PS Nobody has yet guessed this weeks technology challenge correctly - first one to do so gets a £5 prize. I have copied the challenge and a clue below.

Freshers Drinks:
Tuesday 11, 20.15-22.00 St Catz PDR
Come along to talk geek, have a few drinks and nibbles on us and to
generally find out what the society is. If you can't stay for long, feel
free just to pop in for a quick drink and a chat.
Here is a handy map for finding Catz: http://g.co/maps/eeut2

Technology Competition:
Challenge 1:
This week the challenge is a really easy introductory one:
"What does our logo mean?"
This week we will only be awarding a prize to new members - as
our older ones already (hopefully!) know what the answer is.
Once you have figured it out go to
http://compsoc.dartoxia.com/answer/<ANSWER GOES HERE>.
Anyone (with a .ox.ac.uk email address) can sign up to the competition
through the http://compsoc.dartoxia.com website, but

Dear all,
You're receiving this email because you signed up at *last* year's
Freshers' fair for information about the Computer Society. I just
wanted to pass on some news about the society. I had intended to send
this to the freshers' list at the time but obviously neglected to.
I sent this announcement to current members earlier in the year:
<http://www.ox.compsoc.net/news/Society_inactive/>
Essentially the society was unable to elect a committee last year so
it's now inactive, and will need to be wound down over the next year
or so unless someone would like to take a role in running it.
This is the last email you'll receive from the freshers' list; I will
remove everyone from it after sending this mail. If you will still be
interested in receiving general announcments about Compsoc activities,
please feel free to sign up to the compsoc-announce list at:
<http://lists.ox.compsoc.net/mailman/listinfo/compsoc-announce>

Dear Compsoc,
There's a rather special event happening tomorrow (Tuesday of 6th Week)
at 7:30pm in the Lindemann Lecture Theatre in the Clarendon Laboratory...
/*Visual Effects: Using science and maths in the film industry*
Have you ever considered working in the film industry? A career in
visual effects can be an ideal path for people who want to do something
creative with their science and maths skills. On Tuesday night, three
industry professionals - Eugénie von Tunzelmann, Nicola Hoyle and Jeff
Clifford - will be coming to talk about roles for scientists and
mathematicians in the VFX world, and how their technical skills have
been used in films such as The Dark Knight, 2012, Hellboy II and the
Harry Potter series./
Hope to see you there,

Meet at Gloucester Green bus station on George Street at 9:15am if you
want to come on the trip to Bletchley Park. It will be a fun day.
In addition, we will be having a talk by Ensoft next Thursday. The last
talk they gave was very successful. Venue is yet to be confirmed.
- Jon
-------- Original Message --------
http://www.bletchleypark.org.uk/
This Saturday the 31st, the University of Oxford Computer Society will
be travelling to Bletchley Park. We will be catching the X5 bus to
Milton Keynes (at a cost of £10.50 for a return ticket) and then taking
a 10 minute train trip (at a cost of £3.10 for a return ticket) to
Bletchley. Entry to Bletchley park is £8 if you have a BOD card, £10
otherwise. Once you have bought a ticket you can in fact use the ticket
for up to 12 months after it was bought.
We will meet at Gloucester Green bus station on George Street at 9:15am
on Saturday, and will probably be back in Oxford by 6 or 7pm (when we
leave is generally left up to consensus).
Bletchley park is an amazing place to visit, and if you think you might
want to come *PLEASE EMAIL ME* so that we have a rough idea of numbers :)
Hope to see you there,
- Jon
PS: Do not bring anything that could be construed as an offensive
weapon, or any controlled substances as security is pretty tight there
and they are likely to take a dim view.

Dear Freshers,
This coming Thursday (the 15th) the staff at Oxford University Computing
Services have graciously invited us on a tour of their data centre. The
tour starts at 17:30, and *YOU MUST BRING YOUR BOD CARD* otherwise the
receptionist will not let you in. You will get the opportunity to:
- See lots of computers, flashing lights, cables, air conditioning ducts
- See the amazing robot arm that moves hard disks around and then
punches you in the face
- Ask awkward questions about file sharing (don't do this)
- Complain about nexus email (don't do this either)
- Ask genuinely interesting questions about sysadmin/operating
systems/bandwidth
Afterwards, we will go to the pub, where you can talk to people who
won't glaze over if you start talking about something vaguely technical.
The person to ask the best question(s) on the tour gets a free drink at
the pub afterwards!
Hope to see you there,
Jon

It's the penultimate week of CompSoc this term, and
one of our own is stepping up to the plate this week...
The CompSoc Network
===================
Speaker: David North
Wednesday 26th November, 20:00
Lecture Room B, Worcester
CompSoc's chief sysadmin, David North, will talk about CompSoc's
network of machines, their history, what they do now,
and how you can get involved.
There'll be people at the Worcester College lodge to
direct you to the room.
David is infamous for his graphs, which are one of the many
good reasons to come along to this talk. The network has
almost been around longer than some of us have, but it's still
going and maintained by our team of crack sysadmins; there's
plenty of stuff on there members can use, so if you don't know
about them, come along and find out!
See you there.
Andrew

It's week 5, and to combat that well-known feeling
of Fifth Week Blues, there's a wonderful talk to come along to!
Introduction to the Google Web Toolkit
======================================
Speaker: Martin Hutchinson
Wednesday 12th November, 20:00
Pusey Room, Keble College
Martin Hutchinson, of DecisionSoft [1], will give an introduction to
the Google Web Toolkit (GWT). GWT is a Java framework that lets
you write Java and have it automagically turn into clever, AJAXy
and otherwise Web Two Point Oh interfaces.
As usual, we'll be waiting at the Porter's Lodge at Keble to
point you in the right direction.

Hope to see you there!
