Raspberry Pi 2 Model B – Let the fun begin!

Pi2ModB1GB-scale

I finally broke down and ordered a Raspberry Pi 2 Model B and here are my first thoughts after tinkering with this $35 device for a few hours. The default username is “pi” while the default password is “raspberry”.

In short I’m just flat out impressed, it’s amazing how far technology has come and what you can do with a $35 device. I haven’t touched a breadboard in more than 20 years now but I’m excited to pick one up and start tinkering again. The electrical engineer in me is giddy with excitement and anticipation. While the computer scientist in me is eager to write some code and see how this little device can literally integrate into the real world.

I was impressed by how responsive the GUI was on the Raspberry Pi 2. It felt faster then some of the older Intel Core 3 laptops I have lying around the house. Using the USB 2015-08-21-230509_1632x1018_scrotwireless adapter that was included in the kit I purchased I was quickly able to get the Raspberry Pi to join my WPA2-PSK wireless network. Within 15 minutes I had a X windows desktop (you need to manually start X Windows with ‘startx’ from the command line interface – that reminded me of my early Linux days). I was also able to remotely connect via SSH using PuTTY to the little computer. The Raspberry Pi 2 uses a microSD card as the primary storage filesystem. I was again surprised by the performance of the 8GB Kingston microSD card that was included in the kit.  I’ve run a few live Linux distributions from CD/DVD and/or USB flash drives and the performance is always painfully slow. In this case the performance was transparent as the solution just worked and I didn’t need to bother about the bottlenecks because there were no visible performance issues.

Here are a few commands I used to update the Raspbian Linux distribution to the latest and greatest;

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

I’m going to document how to setup a Raspberry Pi 2 as a remote PRTG probe. That should be fun.

Are you using a Raspberry Pi or Arduino? What are you doing with it?

Cheers!

ISC BIND 9.10.2-P3 Forwarding Caching Only Nameserver

bind9ubuntu

I recently had to migrate a large DNS environment from about 23 Microsoft Domain Controllers to Infoblox DNS. I could have just deleted all the zones and set the forwarding on the Microsoft DNS servers but I wanted to leave the Microsoft DNS configuration and data in place to provide a quick backout option in the unlikely event that it was need (it was needed but the second time around using the named.conf file below was the charm). I ended up deploying ISC BIND 9.10.2-P3 across a mix of Windows 2003 and Windows 2008 domain controller servers, some 32-bit and […] Read More

Avaya ERS 3549GTS-PWR+ Stacking

avaya-ers-3549gts-pwr-48-port

I had an interesting experience yesterday working with a client who had a stack of 3 Avaya Ethernet Routing Switch 3549GTS-PWR+. The units were properly cabled but they wouldn't stack with each other. In the past while working with the Avaya Ethernet Routing Switch 4000 or 5000 series you only needed to physically connect the stacking cables and power on the switches and they wouldstack together. You might have to check which switch was set to base using the dip/selector switch on the back of the switches, but there wasn't much to it. I spent about 30 minutes fumbling with these […] Read More

Moving SHA-1 Certificates to the SHA-2 Certificates

i-0-lost-bits-5-1243478-scale

This week I decided it was past time to address the visual warning that Google's Chrome and other web browsers are showing when connecting to the discussion forums. That site had been protected by a SHA-1 certificate issued by RapidSSL, which is owned by GeoTrust, which is now owned by Symantec. Now that I work in the retail sector my team has been very focused on replacing all the SHA-1 certificates that we use throughout our customer facing e-commerce infrastructure. No small job when you have hundreds of certificates out there with dozens if not hundreds of third-party vendors. When you'd […] Read More

Rollerblade Macroblade 90 – Impressive Skates

macroblade90

This morning I debuted a pair or Rollerblade Macroblade 90's on the Schuylkill River Trail between Pawlings Road and Rt 202 in Norristown, PA. It was a leisurely 13+ mile skate as I tested out my new skates only occasionally pushing the pace when I needed to pass some bikes. The skates are relatively comfortable, even while breaking them in. I ended up getting only small blisters on both feet (on my big toe nonetheless). The skates provided an extremely smooth and silent ride with great excellent power transfer in each stroke and great stability through each stride. As is […] Read More
