Why I switched to Go (golang), the next great programming langauge

I have been asked a lot as of late, why I switched to writing code in Go.  The answer is pretty simple and to quote another developer;

• The language is modern, small, simple and quite strict. There's a minimalism here that I like - what you see is what you get. Some things that wouldn't even merit a warning in other languages (like unused variables) are errors in Go - your code won't even compile. I like the tidiness this promotes.
  
• Awesome concurrency. Go's concept of goroutines and channels is simple, beautiful and works well. This is essential for something like syncthing where there's a lot of stuff going on in parallel.
  
• Simple deployment. Go compiles to a single statically linked binary that you just need to copy to the target system and run. It's trivial to cross compile from one os/architecture into all others supported by the Go compiler.
  
• Modern standard library, "some batteries included". This includes an HTTP server, a clean (non-OpenSSL) crypto and TLS implementation, JSON and XML serializers, etc.
  
• Good enough performance. The Go compiler doesn't generate as fast code as the best C or C++ compilers out there, but it's still faster than interpreted languages.
  
• Tooling and community. Go does things somewhat differently than many other languages and this can be a bit of an acquired taste... But for example the existence and adoption of "go fmt" means there is no discussion about formatting or indenting - there is only one standard. "Go get" simplifies fetching and building, plus results in a standardized repo layout. Etc.
  
• I think it's a really nifty language to work with and IMHO, it is the next great system language.
  
• It has the backing of a fiscally stable company, Google. So if anything it will only increase in popularity.

Mac OSX Yosemite Draft eMail Problems

I finally upgraded my day-2-day notebook to Yosemite 10.10.2 and quickly noticed a very annoying problem with Apple's Mail client.  Mail automatically saves drafts of emails as you compose them, which is okay and to be somewhat expected.  However, the problem was, it would not delete the draft(s) after I sent the actual message and I had already turned off the "Store draft emails on server" function, years ago.

The solution I found that worked for me was to turn off the new "Automatically detect and maintain account settings" feature located in Preferences, Accounts, Account Name, Advanced, as shown in the screenshot below.  After unchecking that check box for all of my accounts and their corresponding SMTP servers, I restarted Mail and everything now works as expected. 

Sublime Text 3 Auto Complete Theme / Color Changes

After recently switching from Eclipse to Sublime Text 3 for my development work, I found the need to change some of the theme and element coloring options. One of the elements I wanted to change, but could not find any documentation for was the auto complete pop-up window. 

In the following screenshot you can see a pop up window with a list of auto complete options.  Let me explain how you might change these.  First off, the file you will need to edit is this one: ~/Library/Application Support/Sublime Text 3/Packages/Theme - Default/Default.sublime-theme




To change the background for the pop up window you would edit this element:
{
  "class": "popup_control",
  "layer0.tint": [64, 64, 64, 255],
  "layer0.opacity": 1.0,
  "content_margin": [2, 2]
},
{
  "class": "auto_complete",
  "row_padding": [2, 1],

  // White background
  "layer0.tint": [255, 255, 255],
  "layer0.opacity": 1.0,
  "dark_content": false
},


To change the color of text item is the pop up  window you would edit this element:

{
  "class": "auto_complete_label",

  // color of options in pop up window
  "fg": [72, 72, 72, 255],

  // red, the text color that you have typed that matches
  "match_fg": [255, 0, 0, 255],
  "bg": [255, 26, 26],

  // color of the text in the row that is selected 
  "selected_fg": [72, 72, 72, 255],

  // black, color of the matched text in the row that is selected
  "selected_match_fg": [0, 0, 0, 255],   
  "selected_bg": [156, 185, 223, 255]
},


To change the row highlight color you would edit this element

{
  "class": "table_row",
  "layer0.texture": "Theme - Default/row_highlight_wide.png”,

  // Blue highlight for the selected option
  "layer0.tint": [33, 90, 184],
  "layer0.opacity": 0.0,
  "layer0.inner_margin": [1, 1]
},
{
  "class": "table_row",
  "attributes": ["selected"],
  "layer0.opacity": 1.0,
},
