Spent lunch today at the teen Tech Camp being held at Cape Breton University and hosted by Kim Desveaux of Atekelab Mobile Technology Lab. I was honored to be a guest speaker along with Darryl MacLeod and have a chance to influence the next generation of bright young minds looking to enter the world of computer programming. I was sponsored by my employer, Techlink Entertainment who provided me with a few bits of swag to hand out to everyone smile emoticon It was also nice to meet Derek Mombourquette of Island Sandbox who kindly donated the pizza.

Finally took the time to create a dark theme for my development environment. This should be much easier on the eyes than the old one. Especially under low light.

This is hacking, and this is how we learn. I will still avoid bash at all costs though :)

An extraordinary event will be taking place next week on Sunday, October 19. If you are anywhere around Mars, you are in for a treat. Comet Siding Spring will be passing Mars at a mere 139,500 km. That's half the distance between the Earth and Moon and one tenth the distance of any known comet flyby of our planet (that didn't hit us). NASA held an information packed video session that you can watch here. They are actually concerned for all of their equipment in orbit and on the surface of Mars as the debris from the comet will impact shortly after closest approach.
Original air date: 11 a.m. PDT (2 p.m. EDT) Thursday, Oct. 9 NASA hosted a briefing to outline the space and Earth-based assets that have extraordinary opportunities to image and study a comet from relatively close range to Mars on Sunday, Oct. 19. Comet C/2013 A1 Siding Spring will miss Mars by only about 87,000 miles (139,500 kilometers). That is less than half the distance between Earth and its moon and less than one-tenth the distance o...

For anyone that enjoys Minecraft, this is a mining pattern I use to maximize resource yield and minimize digging. Although this diagram is specifically targeted at diamond mining, the pattern works equally well at any depth for other resources.

One of the reasons this pattern works well is that most resource veins are at least 2 blocks wide so most veins will be exposed. I recommend mining out any coal, redstone or lapis that you encounter, even if you don't need them as they produce XP and may lead to exposing diamond that may otherwise have been missed.

I usually cut a long corridor (3x3) at level 11 around 80 or 100 blocks long. I set up a centrally located work area with trunks, furnaces and water. Always carry a bucket of water for hardening lava or putting yourself out after you've fallen into lava.

Cut into the walls with 3 high by 1 wide branches about 20 blocks deep, putting torches every 5 blocks in. I ignore exposed resources for now. When you reach 20 blocks cut across left and right 4 blocks so when you cut the branches on either side of this one, you will know when you reached 20.

Now back track out the way you came and mine any exposed resources as you go. When you reach your main corridor, store your new valuables in a trunk and cut another branch 3 blocks over from the one you just made.

When your whole corridor has been branched, go down to level 5 and repeat but make sure your branches line up exactly between the ones above as indicated in the diagram.

To truly maximize your efforts, read up on enchanting and make sure you only mine your diamonds with a "Fortune" pickaxe which increases the yield on an ore block. It can be tricky getting this particular enchantment so try to at least get a "Silk Touch" pickaxe which will harvest the ore intact allowing you to store it away until you get "Fortune".

If you work with large computer networks then you probably read this. If you haven't, you should probably wait until you can afford to lose a bit of sleep as it will undermine your ability to relax. This is a survey of the many ways large networks have failed and their numerous causes.

I've been discussing Jepsen and partition tolerance with Peter Bailis over the past few weeks, and I'm honored to present this post as a collaboration between the two of us. We'd also like to extend our sincere appreciation to everyone who contributed their research and experience to this piece.

Firefox 29 looks a lot like Google Chrome. I think that's a good thing.

I would have to agree, it is visually more appealing.  However,  I use the mouse to select tabs and keyboard for URL and search via CTRL+L and CTRL+K.

There are keyboard shortcuts for selecting tabs, but I do the same thing as you and open many tabs, so tabbing through them is not practical.

Learning Vaadin. Pretty good so far. I had a great deal of trouble with it a year or so ago mostly related to Maven. It all seems to be sorted out now though. The NetBeans plugin for Vaadin is really quite good.

This presentation has some very important ideas in it and builds a very clear picture of what I've been thinking for some time but couldn't put my finger on. This may allow me to love databases again.
