I stumbled upon Burstcoin lately and it intrigued me. I was not into cryptocurrency prior to this and being a Mac user I found that there was little support available, plus all the tools seem to be targeted towards Windows (and some for Linux). So I thought that I'd put together the steps I used to plot my hard drive for Burstcoin mining in case anyone else finds it useful!

This guide will require use of the Terminal, so get ready for some typing. You will also need to install Xcode from the App Store.

First you will need mjminer source code, you can download it from GitHub here: https://github.com/r-majere/mjminer. After downloading it, unzip the contents and open up the Terminal to the location of where you unzipped these files.

If you haven't used Xcode command line tools, you will be prompted to install them, just follow the steps there and when done return to this guide.

Type in the following in the Terminal (substitute the location of where you unzipped mjminer as required):
 Terminal
cd ~/Downloads/mjminer-master
make


The above will compile mjminer, you will get output similar to this:
 Terminal

To plot your drive, you do not need your wallet running and you don't have to have activated your wallet either. You should, however, activate your wallet by getting a starting burst coin from a facet and then updating your account info, which will cost 1 coin, so you'll be back to zero balance.

While doing that, from your burst wallet, click the More Info link under the account balance to get your numeric ID. This ID will be needed for plotting. You can see where this is found in the screenshot below:

I've had this 2Tb Samsung Story Station laying around for a while. It was used as a back up drive but unfortunately the hard disk inside it died. It's an old USB 2.0 version but I still didn't want to throw it out and did have a spare 2Tb disk laying around. So I thought lets take it apart and replace the broken disk.

I love the retro look of this enclosure, with it's big down-glow activity LED and the round on/off switch that also doubles up as a brightness control for the LED. It would have been a shame to throw it out!

Around the back there is a micro-USB 2.0 and a power connection. The front has the awesome rotating on/off switch.

It's interesting that the screws used to hold the case in place are Torx. Easily removed, I guess they add to the weird modern/retro look of the thing. There are only four of them to remove, two per side.

I've been finding that since I got my new MacBook Pro and installed Java 8 on it, all of the Java Applications that I've been running have been taking an extremely long time to start or to establish network connections. This didn't seem to affect Java Applications that didn't use the network however. Turns out that the problem is to do with the local machine's hostname resolution and is easily fixed.

First you need to find the hostname of your Mac. You do this from System Preferences. Click the Sharing icon in System Preferences.

You will see a box that shows the Computer Name, under that will be the hostname ending in .local. That's what you will need, so take note of it. In my case it was Enzyme.local.

I love a good laptop bag and had my Crumpler for at least the last 7 years. It was time for a change and since I recently got a new MacBook Pro I figured that it will need a nice leather laptop bag to match. I spent quite a bit of time looking for a suitable bag and finally decided on the Pierre Cardin Leather Computer Bag (PC2278) in brown.

Overall the bag is very nicely made and looks awesome. The leather is soft to the feel and there are enough compartments for all of the accessories you're likely to take along with you.

The design is a classic messenger bag with a flip over cover. There's a pocket with a zip on both the front and back of the bag.

The stitching is superb! Love the orange thread on brown leather look.
