Shaw Go Wi-Fi Hotspots in Downtown Vancouver

Wi-Fi everywhere!

Over the past year, more and more ShawOpen Wi-Fi hotspots have been popping up everywhere around Metro Vancouver.

This is incredibly useful for Shaw customers (like me) because it’s so easy to find reliable Wi-Fi access anywhere we go.  If you’re a Shaw internet customer, you get to save several devices so that they can automatically connect to the network without having to login through the portal.

Telus is starting to form their own network as well, under the names #TELUS and #TELUSDirect.  The one advantage they have is that for Telus customers, #TELUSDirect is a secured Wi-Fi network, whereas ShawOpen is an open unsecured network.

I’m hoping that Shaw will consider providing a secure network for customers, but until then we’ll have to use our own VPN services to secure the Wi-Fi connection.

Error: Boot loader didn't return any data

I have come across this error two or three times before, and each time I spend hours trying to figure out how to get my virtual machine to boot.  This blog post is just to document a fix so that I can refer back to it, and hopefully it will help people out if they’re experiencing the issue as well.

Nooner at the Nat

Yesterday, we had a company outing to a baseball game at Nat Bailey Stadium (Vancouver Canadians vs. Everett AquaSox).  I believe this was the first time I have watched a sports game in person, so it was quite exciting even though it wasn’t MLB.

The first few innings weren’t really interesting with quick outs.  Vancouver finally scored a few runs to win the game.  Watching in person has its benefits and drawbacks.  The benefit is that you get to see everyone on the field, but the drawback is that you’re confined to one viewing angle.  The TV definitely offers better angles during the pitch.

This reminded me of when I played baseball many years ago.  I played a couple years of little league baseball at the local community centre when I was in grades 2-5.  It was both a fun and frustrating time.  In my last year, I was the main pitcher on my team and that was definitely fun.  It was frustrating because I was a horrible batter.

More Detailed Wi-Fi Info on Mac OS X

Wi-Fi Detail Menu
Option-clicking on the Wi-Fi icon in the menu bar brings up additional information about the Wi-Fi network to which you are connected.

The option button can be used to reveal hidden options and information in various places around Mac OS.  One example of this is if you option-click the Wi-Fi icon in the menu bar, you will be presented with additional information about the network you are currently connected to, including the type of the Wi-Fi you’re using, the base station’s MAC address, the frequency channel you’re on, and the strength of the connection, among other details.  In addition, there is an additional option to open Wireless Diagnostics which might be able to help you with Wi-Fi issues (however, in my experience it doesn’t really give useful information).

An additional tool to help debug network connections is a neat little utility called “Network Utility” that comes bundled with Mac OS X.  You can find it in the Utilities subfolder in the Applications folder, or just use Spotlight to find it.

This utility provides a friendly interface for many tools that are commonly used on the command line for network debugging, such as ping, nslookup, traceroute, whois, and finger. An interesting tool though is the last tab: Port Scan.  Yes, Mac OS comes with a port scanner bundled with it.  Obviously one would hope that the port scanner be used for diagnostic purposes and not malicious purposes.
