The easiest way to start buying, selling, and mining Bitcoins

Despite all the negative news around bitcoin, I believe cryptocurrencies are the future. Bitcoin may not be the one to take off, but one of them will eventually.

Here’s how I started earning bitcoins.

  1. Create a Wallet: I setup a digital “wallet” with Coinbase where you can save the bitcoins you’ve mined, or just buy and sell bitcoins directly with Coinbase. You’ll need the wallet “address” to spend your bitcoins elsewhere and receive bitcoins from others. You’ll also need that address to get into mining bitcoins, which is what steps 2 & 3 are about.
  2. Join a Mining Pool and setup a Worker: I joined the BTCGuild (no longer a thing) to increase my chances of earning bitcoins. Otherwise you’ll mine for months and may not ever receive bitcoins. In a pool you’re joining forces with lots of other miners and are rewarded based on how much processing power your computer contributes to the pool’s efforts. You get smaller increments of coins, but you get compensated more consistently. These days I’d try something like the Pool or Slush Pool
  3. Setup a Miner: I installed Asteroid (no longer a thing, try this instead Mac Miner) on my Mac Pro to start mining bitcoins. Asteroid will ask you or the name of the Worker you setup in step 2. After following a few more instructions your mining bitcoins. My computer is a beast, but its easily brought to its knees when I have the miner running. Asteroid let’s you throttle the mining intensity so you don’t crash your computer, but be careful. If you choose to allow Asteroid to use your graphics card for mining, it may appear to freeze your computer. There are lots of devices you can buy specifically for mining that are faster than your desktop or laptop.

Each of those 3 steps takes about 5 minutes or so, but may take longer to really understand what each step is about.

  • TidBit – Earn bitcoins by letting your visitor’s computer mine bitcoins for you while they visit your site.  This will be the end of website display ads when the finish beta testing. [No longer a thing]


After about a week worth of letting my computer mine for hours everyday if earned about 0.00001497 BTC, which converts to about 0.01293 USD (2014) according to this bitcoin to USD converter. So… with my current hardware setup it would take months to earn enough to buy anything. However, if I bought some fancy but inexpensive bitcoin mining hardware I mentioned earlier, I’d be earning at a much faster rate. Either way I’ll probably keep mining. I may even convert a few dollars into BTC. Given the state of the world, a multi-currency strategy couldn’t hurt. Like the saying goes, “Don’t throw all your babies in the egg water.” Or whatever. Let me know if you try it out. Happy mining.

    To manually install Silverlight please follow the steps outlined below:

    (Note: when completing these steps make sure you have quit our of all running Applications and that they have not just been minimized to the Dock)

    1. Launch your web browser (FireFox/Safari) and visit
    2. On the lower right side of the screen you will see Install Silverlight, Choose Silverlight Mac Runtime and allow this to download to your desktop. If the installation automatically launches quit out of it and complete the following steps.

  4. Create a new user

    If this is unsuccessful there might an issue with your user account preventing Silverlight from working correctly. What we would like to do is test a new Mac user. To create a new Mac user:

    1. Go to System Preferences
    2. Go to Account
    3. Choose the Plus sing in the lower left corner to open the new account window, enter Test for the user name, leave the password blank

    5. Choose Create Account
    6. Now logout out of your original account and login to the Test account
    7. Once in the Test Account visit and go to Showcase, if you can view this page without being prompted to install Silverlight then it has installed successful
    8. Visit NetFlix to make sure that you are able to access their content.
  5. Contact Apple

    If Silverlight works with the new Mac user you will need to contact Apple and have them decide why the original user will no longer allow Silverlight to work.

  6. Check Browser’s Rosetta settings

    If this fails another suggestion we can make it to check to see if the browser is running with Rosetta enabled. To verify this please follow the following steps. (NOTE: you must quit the browser to follow these steps)

    1. Open your Mac HD
    2. Go to Applications

    5. Under General Make sure the box that says Run using Rosetta is not checked
    6. Launch browser and attempt to launch content on NetFlix
  7. Check for corrupt fonts

    If this fails then there might an issue with corrupt fonts within your
    operating system that is not allowing Silverlight to load when attempting to access NetFlix content because NetFlix uses DRM formatted content and corrupt fonts can prevent this type of content from loading.

    The next step will be to manually install the Arial and Verdana fonts to do so please complete the following:

    1. Go to the Hard Drive
    2. Then Applications
    3. Then Font Book
    4. Choose the Verdana font, and go to File, and Export Fonts. Name the folder Verdana.
    5. Then choose the Arial font, and go to File, and Export Fonts, and name the folder Ariel.
    6. Go to the desktop, and look for these two folders.
    7. Go inside each of these folder, then another folder with the name of the font. You will see multiple folders in here. You will need to go inside each of these folders, and copy all fonts located here to HD>Library>Fonts
    8. Restart the computer.
    9. Attempt to view Netflix content.

How I discovered the Netflix DRM Error N8151

My wife and I decided to sign up for Netflix again. We cancelled several months ago, but after buying a few kids movies on iTunes, we started to miss having access to loads of toddler-taming flicks for the price of one movie purchased from Apple.

Netflix had all of our account info on file. After three clicks I was back. My Instant Queue was stocked with everything I added before canceling. I was ready to sit back and watch a show.

I heard that the recent launch of their new interface design was a debatable attempt to make the site more user-friendly. Either way, I was excited to try it for myself.

I clicked my selection and waited for it to load. Instead of opening credits, I saw this:

Bummer. Anticlimax. I had seen this error before. During my previous Netflix subscription I had to burn a long evening on the phone with support to fix the problem. The problem was frustrating but fixable, so I wasn’t too worried.

Digital Rights, Smigital Rights

After a little googling I found the help I needed.

The error has something to do with Silverlight, a Microsoft technology Netflix uses for their video player. The details of why, how and what circumstances triggered this error do not interest me. I just want the thing to work.

Within a few minutes I found step-by-step instructions from Microsoft Silverlight Technical Support on how to address each possibility.

In my case everything was fixed after trying the first step. The movie cloud was back!

I could simply post a link to the forum where I found all the answers, but then I would have to find that forum if I ever ran into this problem again. So, I’m posting the process here to help myself and maybe others who have a similar problem.

I hope this helps others fix this problem quickly so they can get back to watching their favorite show.

What’s the best computer for graphic design: Mac or PC?

WARNING: This post contains completely biased opinion from a Mac user.  You may experience entertainment and a desire to purchase Apple products. If symptoms persist for more than 30 days, save your money and call your local Apple dealer.
Mac vs PC ad guys

Nick Elam, sent me a controversial question that inspired this post:

What kind of computer do you suggest for graphic design? Mac? PC?
My laptop is too slow to handle my graphic design work lately so I’m looking for a new computer. Lots of people say “go with a Mac”, but I could build a PC with a faster processor and better video card for a lot less. What do you think?

I’ll answer Nick’s question with pure opinion. I don’t feel the need to regurgitate a balanced Mac/PC debate. That’s been done, and that’s what links are for:

Quick summary: I use Macs.

  1. As a graphic designer, the tools you use daily will influence your work on some level.
  2. Apple is able to “design” the entire user experience of their products since they build the hardware and software themselves.
  3. If your budget is an issue, find a refurbished or used Mac. They hold their value extremely well. I bought a 2006 iMac 24″ as a family computer in 2009. After we replaced the video card in 2010,  it functions perfectly, even with the latest Mac OSX installed. It’s definitely not as swift as my 2011 Macbook Pro, but it get’s the job done.

Let me start by saying buy a Mac

Apple Mackbook Pro 15 inch early 2011
My current laptop 2011-2013

And let me follow that up by saying buy a Mac now. I don’t care if you can mine silicon, weld transistors, and engineer the motherboard yourself. Using a Mac is better than using a Windows PC for graphic design, like using a pencil is better than a rock and chisel for drawing portraits.

I’ll explain.

Space defines action

I believe your environment influences your work. As a designer it makes sense to use things that are well designed. Interacting with a well designed product actually teaches you how to design better.

User experience trumps hardware specs

Apple Vs Microsoft Switchboard
Now that Intel Macs can run both Windows and Mac OSX there is no need for other hardware. If you are only interested in comparing hertz and bytes, then there isn’t much difference between a Mac and a Windows PC. However, by only comparing hardware specs you’re missing the bigger picture. As a graphic designer your computer is your business partner. You will spend hours everyday interacting with this machine. Designing your latest masterpiece, communicating with clients, sending out invoices, getting lost in a Twitter/Facebook hole; all of this happens on this one device. That’s why I believe the software on your box is a little more important than the metallic bits inside.

This is where Macs move way ahead of PCs. The Mac operating system is an intuitive streamlined environment. It simplifies basic interactions, and doesn’t get in the way productivity. This efficiency will pay big dividends in the daily grind of being a graphic designer.

Modern Macs can do it all

I use a Mac for all computing purposes, except for the occasional website debugging that I have to do for Internet Explorer. Internet Explorer isn’t made for Macs anymore. This means I must traverse into the nether regions of darkness to find a cheeto-encrusted Windows-based PC to test my website. Even testing Internet Explorer bugs. I simply open Parallels and can swipe between Mac & Windows easily.

The necks of PC fanatics are thick with veins by now. I haven’t given a lot of statistics, references and bar charts to prove my theories. But as I said before, I’m simply voicing the opinion that’s been formed in me after years of working with both Macs and Windows-based computers.

I choose mac. What do you use?

UPDATE! Windows 8 is a game changer and definitely put the Microsoft Windows' UI in a better place. Definitely check it out, use it, learn from it. But as of 2013, I'm still leaning Mac. After a few iterations on some of Microsoft's new concepts in Windows 8, I may be singing a different tune.

How to edit your host file on a Mac

Apple's Terminal App Icon

Changing the contents of a computer’s host file is extremely helpful skill for web developers to have. You can basically manipulate the way your computer looks at the internet. I use it to keep Google Analytics from counting me as a visitor on my site (or any site for that matter). Whatever your reasons for editing your host file, here’s how to do it on a Mac.

1. Open Terminal

2. Type: sudo pico /etc/hosts

3. Type: YourPassword
*This is the same password you use to log in to your computer

4. Edit host file

5. To save your changes hold down CONTROL & press the letter ‘O’. Then press ENTER

6. To exit your host file hold down CONTROL & press the letter ‘X’.

7. To quit Terminal simply hold down COMMAND & press the letter ‘Q’ at the same time.

And that’s it. You’ve just edited your Mac’s host file.
