Crustal evolution assistance

Ooh – incoming email:

Dear 6000,
I am a geology student from the UK and I am looking for some assistance with a project on the geology of Table Mountain. Since you mentioned this subject in a post recently
[I did? Oh yes. I did. – Ed.] and you are based in Cape Town, I wondered if you might be able to help me out.
Specifically, I am looking for a photograph showing the effect of cross-cutting faults separating multiple peaks of Table Mountain Group sandstone on an eroded granite basement together with some indication of the proximity of this phenomenon to the Western Seaboard of the Cape Peninsula.
I really hope you can help.
Best regards,
Steve Green.

Woo. Toughie. You’re asking for a lot of detail in one photo there, Steve.

Fortunately, I have scoured the 6000 miles… photo archives and found the perfect image for your project, detailing everything you require.


There you are Steve, I hope it meets your needs.

Off

I shared this elsewhere yesterday, but that doesn’t stop me sharing it here today.

Firstly, the bad news. It’s a door handle. I want to tell you about a door handle.

How exciting can that be? Well, I think it’s pretty cool, actually:

So, you and the family is going on this big vacation and just as you finish locking up everything and shut the main door, your wife calls out – hon, did you check the gas and switch-off all the lights? Sounds familiar? How about if you had the ‘Off’ installed! It is a door handle with connections to your mains like gas supply and electricity. Simply switch off both or either one of the services by rotating the dial and flip it back to activate it all. Super cool and innovative I tell ya!

Look, we don’t have gas here, but we do have a two water heaters and a pool pump which would CHOW electricity (despite this) if we left them on while we headed down to Agulhas (or wherever).

What a brilliant idea: saves electricity and gas, reduces nagging, saves time, prevents stress.

Secrets of the fixture computer

After a question from @chickenruby yesterday evening, I found myself wandering back onto Paul Fletcher’s 2009 blog post, detailing the immense amount of thought that has to go into organising the fixtures for the English football leagues. Thankfully, Paul did the work so we don’t have to:

I wanted to find out exactly how the fixture list is put together and just how difficult a job it is. Needless to say, I spent a large chunk of last weekend in a dark and cool room as my brain tried to come to terms with its most serious case of information overload since I asked my wife to point out my most obvious flaws.

There’s a bit more to it than simply ensuring that The Mighty Blades and the snort-beasts from S6 don’t end up playing at home on the same day:

Putting the fixture list together is incredibly complex – with a whole series of factors ensuring it is an increasingly difficult task.

Just to give you one example; every club is paired with another in regard to when they play their home and away fixtures. This is done for a number of reasons, one being so that clubs like Everton and Liverpool do not play at home on the same weekend.

West Ham, it turns out, are paired with Dagenham and Redbridge. But for reasons of revenue Southend request they do not play at home on the same day as the Hammers as they believe it impacts upon their attendance.

Southend, though, are in Essex, as are Colchester, so they cannot play together on the same weekend. Colchester share stewards with Ipswich so those two clubs also request they do not play home games on the same weekend. Transport links dictate Ipswich and Norwich do not play together on the same weekend either. In other words, when West Ham play at home can have an impact on when a club as far away as Norwich (108.8 miles) play their home fixtures.

And there are 12 other professional clubs in London…

But if you think that that describes the full complexity of the system, think again. Because then you have to avoid fixtures clashing with European games, International friendlies, World Cup qualifiers, English cup competitions, big local events and the like. Then you want to limit the amount of distance fans have to travel on public holidays when public transport options may be limited.

And then there’s the individual requests of each club.

As Fletcher notes:

…it must be an agonising, head-scratching process that slowly strips you of the will to live.

For instance, every time a fixture is changed it affects at least seven other fixtures and can easily impact on as many as 48.

The whole article carefully details the entire process and is well worth a read, even if you’re not a big footy fan.

Death By Life

Late nights, disturbed sleep, early mornings. It all adds up and suddenly I realise again that I’m not getting any younger.

We spent the afternoon at a wedding overlooking Simonstown, a few miles down the coast from Kalk Bay where we partied until late last night.
False Bay is beautiful, but I don’t want to go back there until I’ve properly recovered.

Mind. Blown. (Episode 47)

Here is a robot made of lego and powered by a cellphone.

CubeStormer II solves the Rubik’s Cube puzzle faster than the human world record.

This ARM Powered robot was designed, built and programmed by Mike Dobson and David Gilday, creators respectively of CubeStormer http://youtu.be/eaRcWB3jwMo and Android Speedcuber http://youtu.be/ylFb4pqAUd8.

Ja right? Ja. Right.

 

Look, I’m no expert, but it looks to me as if:

The mechanics are constructed entirely from LEGO, including four MINDSTORMS NXT kits, with the addition of a Samsung Galaxy S II smartphone running a custom Android app as the robot’s brain. Both the MINDSTORMS NXT kits and the Samsung Galaxy SII use a variety of ARM –based processors.

The app uses the phone’s camera to capture images of each face of the Rubik’s Cube which it processes to determine the scrambled colours. The solution is found using an advanced two-phase algorithm, originally developed for Speedcuber, enhanced to be multi-threaded to make effective use of the smartphone’s dual-core ARM Cortex-A9 1.2GHz processor. The software finds an efficient solution to the puzzle which is optimised specifically for the capabilities of the four-grip mechanism. The app communicates via Bluetooth with software running on the ARM microprocessors in the LEGO NXT Intelligent Bricks which controls the motors driving the robot. During the physical solve, the app uses OpenGL ES on the phone’s ARM Mali-400 MP GPU to display a graphical version of the cube being solved in real time.

Human speedcubers’ solve times only include the physical manipulation of the cube and don’t include some time which is allowed to “inspect” the cube beforehand. Times recorded by CubeStormer II are for the total solve including: image capture, software solution calculation and physical solve.

Now I just need an Android-powered lego robot to pick my jaw up off the floor.
