Coinitor - a bitcoin wallet monitor

A bitcoin wallet monitor.

Add in your bitcoin wallet public address (up to 3 wallets can be monitored at once) and this desktop app simply shows you the balance, the value in a currency of your choice and the number of wallet transactions.

The background bitcoin value barchart shows live data.

This is more secure than logging into your actual wallet to check the balance as it requires no passwords and doesn't need to know your private wallet key. It simply queries the blockchain to access public information about your wallet. In this way keyloggers etc will not pick up any useful info while you query your wallet.

Mountain Bike - rolling resistance tests

Peter Nilges has done some scientific testing in his dissertation (at the German College of Physical Education, Cologne) on the rolling resistance of mountain bike tyres under varying conditions. The results were a surprise.
While on tarmac thinner, higher pressure tyres have a lower rolling resistance the opposite is true for off-road riding.

Another reason to switch to tubeless, which not only helps prevent punctures, but can be run at a lower pressure (and depending on the system you use can save weight, or more importantly, rotational mass).

Apt.....But bitcoin is probably far from dead.

Here's what happened:
MTGox, the biggest bitcoin exchange (apparently something like 90% of all bitcoin-fiat currency transactions went through here) had some bad code which allowed people to 'Double Spend' bitcoin that was held by the exchange. This theft went on unnoticed for several years and amounts to some 750,000 bitcoin going missing.

A huge number of webcams are unsecured, meaning that anyone on the internet can access the feeds. As they have web front ends, Google even lists them in their search indexes, making them even easier to find. Eg: Google search.

Some websites are even dedicated to listing unsecured cameras.
Here's some examples:
livesecuritycams.com

Most of them a pretty mundane, car parks and the like.

There's also lots of deliberate sharing, like this guy with a camera on his truck:

Bitcoin UK

So....everyone's probably heard of bitcoin, the digital currency that's supposedly changing the world.

While it's far from certain that bitcoin will survive, it is true that digital currency in a similar form is here to stay.

I've been playing around buying a small amount of bitcoin (and spending it on takeaway when it's value goes up) to understand how it works. In the UK it's not hugely easy to get hold of or spend. That fact that, like any new product/service, there are dodgy people trying to take advantage of people's lack of knowledge doesn't help matters.

Here's some lists of a few current trustworthy UK bitcoin sellers and businesses who accept it:

A good place to get an overview: (you'd don't need to do the sign in with facebook or sign up to coinbase bits)

Set up an online wallet:

Blockchain.info

NOTE: This is a good starting point. However, like a real wallet, only keep small amounts or spending money in here long term. You are trusting the wallet host not to suddenly disappear or be hacked.
Also, make sure you make a backup of the wallet (easy to do through the main interface).
If you have any significant money in bitcoin, you should move it to an offline/paper wallet.

Ai Pioppi - Fairground in a forest

"Hidden among the trees of an Italian forest, Bruno has been building swings, slides, seesaws, gyroscopes and roller-coasters for the last forty years. They are his passion and a way to attract clients to Ai Pioppi, the restaurant he runs with his family. Throughout this short documentary, his hand-powered toys move alongside his thoughts about existence and death; and why he spent more than half of his life creating rides."
