All posts for the month February, 2015

The 2015 Reebok CrossFit Games Open is about to start on Feb 26th.  The Open started in 2011 where people all around the world was able to compete in a 5 week competition to get a chance to make it to the CrossFit Games in Carson Califonia.  Each week on Thursday a workout is posted and you have till Monday to submit your scores.  Workouts were either performed and judged at an official affiliate or video taped and uploaded to the site.  I have competed in every open since I started CrossFit in 2011 and I have to say it really is a great way to bring members of your box closer together and have a lot of fun.


Every year I always get nervous when the open is announced and it’s sign up time.  I always think of the gut wrenching feeling I get on Thursday evenings when I’m glued to the screen waiting for the WOD announcement, the shock when I hear the announcement and the over analyzing of how to get the best score.  I look back and think, why do I do this to myself and then remember the fun and great times I had during the open.  The open is a time where you get to meet new members and see members of your box you rarely see due to different schedules, you get a huge crowd cheering you on while you give everything you got on the floor, you get to see amazing feats of strength and athleticism, and best of all you get to see your friends PR and people surprising themselves of what they can really do.


This year I really didn’t think I was going to sign up for the open for a couple of reason, one being the addition of my baby boy to our family and the other I started focusing on my lifting.  I haven’t done a CrossFit WOD since October when our box had an in house competition.  So it’s been three months since my last WOD and I can definitely say my cardio and gas tank has definitely suffered.  My diet and sleeping patterns also aren’t the greatest since I’m learning how juggle being a parent, working, training and still trying to enjoy my tech hobbies.  However as the deadline to sign up for the open comes closer I thought about all the great times I had and decided to sign up.  I know it’s going to hurt and I know I won’t be going to regionals but I’ve learned to just have fun and give it your best.

I registered for the 2015 Reebok CrossFit Games….HAVE YOU?

So yesterday I posted how to create a full node for any altcoin which is good if you want to support a coin and provide a full node.  Today I will show you how to compile a QT wallet from source.  This post assumes you have already followed the first three steps in my previous post of building a full node and running Ubuntu locally attached to a monitor.  You should have the git source for your coin in your user home directory already, however you will need to add one more dependency so you can compile the QT wallet.

sudo apt-get install libqrencode-dev

Compile QT wallet

cd PayCon

Load config file into data directory

nano /home/user/.PayCon/PayCon.conf

Paste config information from ANN post of coin and save it

Launch wallet

Once you have synced up with the blockchain it is HIGHLY RECOMMENDED that you backup your wallet to somewhere safe. The wallet for each coin is always located in their respective hidden folder under the user directory. You can the directory if you use ls -la user the home directory /home/user/

user@ubuntu:~/.PayCon$ ls -la

Since March of last year I started getting into cryptocurrencies and have learned a lot of things about it and truly believe in the technology behind it (blockchain).  Bitcoin was just one application of the blockchain technology and people are now trying to build more uses with blockchain technology.

Alot of different altcoins have spun off of Bitcoin, most known ones include Litecoin (LTC), Dogecoin (DOGE), Darkcoin (DRK).  However almost a new alt launches everyday and most turn out to be a scam with devs claiming huge pre-mines or ICOs then dump the coins once it is listed on an exchange.  I won’t get into all the different scam coins since this isn’t really the post for it, but I have decided to help run a full node for the altcoin PAYCON (CON).  Check out the thread for why the coin was created.

Back to the intention of this post, I wanted to build a full node for a coin and tried to search on how to build it with CentOS (Bad idea).  It seems most nodes are built on Ubuntu but information seems to be scatter around in different posts so I decided to put everything in one location and hopefully it can help people out.  You will need to use Ubuntu 12.04 LTS, I’ve tried Ubuntu 12.10 (apt-get issues) and Ubuntu 14.04 LTS (libqt5core5 issues).  This guide is done assuming you are building from source and a minimal install of Ubuntu.


Update all repos and install git

sudo apt-get install python-software-properties
sudo apt-add-repository ppa:ubuntu-sdk-team/ppa
sudo apt-get update
sudo apt-get install git

Obtain coin source code from git (Paycon example)

git clone

Install prerequisite packages for Bitcoin or any altcoin.

sudo apt-get install build-essential libboost-dev libboost-system-dev libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev libssl-dev libdb++-dev libminiupnpc-dev qt5-qmake libqt5gui5 libqt5core5 libqt5dbus5 qttools5-dev-tools

Once all prerequisite packages have been installed move to the coins src directory to compile it. (Paycon example)

cd PayCon/src/
make -f makefile.unix

**Troubleshooting tips**
If you get the following errors
g++: error: /home/user/PayCon/src/leveldb/libleveldb.a: No such file or directory
g++: error: /home/user/PayCon/src/leveldb/libmemenv.a: No such file or directory
make: *** [PayCond] Error 1

Here’s how to solve it
cd /home/user/PayCon/src/leveldb/
chmod 755 build_detect_platform
make libleveldb.a libmemenv.a
cd ..
make -f makefile.unix

Once it finishes compiling you will have PayCond inside your working directory. You can move it to /usr/bin to maintain consistency.

sudo mv PayCond /usr/bin/

Now to create a user to run PayCon

sudo adduser paycon

Now you’ll have to run PayCond to create the configuration file.

Error: To use PayCond, you must set a rpcpassword in the configuration file:
It is recommended you use the following random password:

Once you get the output for rpcuser and rpcpassword and paste it into /home/paycon/.PayCon/paycon.conf

Now you are ready to start the daemon by logging in as the new user you created.


To ensure everything is working you can check the debug log and if it is loading the blockchain you are all set.

tail -f ~paycon/.PayCon/debug.log

Enjoy and hopefully this has helped out.

I’m a big fan of Android and love the way you can customize it to your liking.  I’m what you can call a flash-a-holic.  I love flashing my phone with the newest nightlies.  Currently I’m using Temasek’s CM12 Unofficial Nightly for Bacon.  I like the sabermod version as I personally think it is faster than the Linaro version.  The latest is build 6.9 on Feb 3rd and I just flashed it this morning.  Since my flash this morning around 8am I’m down to 66% battery life with moderate use and 3-4 reboots to finish off customizing it to my liking.  Below are some of the features that are included with the latest build.  I don’t use all of them but will show some major ones.

1. Lockscreen Weather – I personally love this and use it all the time to get a quick glance at the weather.


2. App Circle – I personally don’t use this but if you want quick access to your apps with a quick swipe from the right it’s there for you.


3. Omni Switch – Replaces the default recent apps.  I don’t use this feature either but has the option to switch apps, kill all and kill all except for active app.


If you own a OnePlus One and wanted to try out a solid Lollipop build give the Temasek build a try.
