GnuCash Accounting Software on the Raspberry Pi

October 22, 2016 Leave a comment

I’ve recently had the need to use some Accounting software to dive into some Revenue and Expense allocation for a company to understand the business better.  There was the hurdle of downloading and buying Quickbooks desktop version or buying a online version instance for a month maybe more, and I didn’t know the Quickbooks user interface.

At one time, many years ago, looked at GnuCash and thought it had potential but never spent the time.  Now that I had the need and revisited GnuCash, much to my surprise, the open source software had improved and I decided to take the plunge and learn it.

I do have an accounting class under my belt from graduate school, so the whole double entry accounting was not new to me, and I was glad to see how the concept of accounts was implemented in GnuCash.  Long story short, I was able to enter about 10 months of bank account data into GnuCash, then allocate expenses to get a quick picture of where 2 major projects were with respect to their direct costs and indirect costs.

I’m thankful that GnuCash was an option and it took me several hours to get the answers I was looking for about this business.  If I used Quickbooks, it likely would have taken me longer and had a cost to it.

Here are a couple screenshots of the GnuCash application, It’s easy to use and free on Linux, Windows, and Max OSX.  I tried the version on Windows also, the data file (FILENAME.gnucash) can be copied/moved and used on Linux too, I tested editing on both instances of the GnuCash data file.

To install GnuCash on your Raspberry Pi, simply run the following commands from a command line:

  • sudo apt-get update
  • sudo apt-get install gnucash

When GnuCash is installed a new icon will appear under the Office grouping.  The version that was installed was GnuCash 2.6.4, and I copied this icon to the desktop for frequent use.

Raspberry Pi desktop update PIXEL

October 5, 2016 Leave a comment

I’m finally getting around to playing with the new desktop interface that was released on 9/28 … PIXEL.  If you want to read more on it and how to install, click on this link to see the raspberrypi.org blog.

This is a very NICE update to the previous user interface and I think kids and adults are going to like it.  The other updates are awesome as well like turning on/off the wifi, RealVNC server, and the SenseHAT emulator.

We computer users have become used to a nice user experience via many different products, nice to see the Raspberry Pi Foundation put some effort into this.

Thanks a bunch!

Here are some screenshots of my Raspberry Pi 3:

Raspberry Pi 101 presentation and hands on station at RRPS NAPAC Meeting

October 1, 2016 1 comment

On Tuesday this week, September 27, 2016, I presented the Raspberry Pi computer to the Rio Rancho Public Schools (RRPS) – Native American Parent Advisory Council meeting.  I had a 15 minute slot to cover this new little computer and show how it can be used as a tool to begin a journey learning about computer science, programming, and how to tinker with electronics.  I passed out two Raspberry Pi 3s and one Raspberry Pi Zero for the show and tell portion.  The audience was enthusiastic and really liked having the four Raspberry Pi 3s in the back of the room to check out and play with.  Here is a link to my presentation and some pictures of the event.  I’m looking forward to taking this talk to some of the local tribes here in New Mexico.

Got several Raspberry Pi 3 computers together to do a show and tell with the Rio Rancho Public Schools (RRPS) Native American Parent Advisory Committee (NAPAC) meeting tonight.  Should be fun!  Look for another post on the results of the meeting.

Two Firefox browser additions you should have

April 7, 2011 1 comment

I’ve been involved with personal computers for a long time, long enough to know a bit about browser security and good tools when I see them.

For one, I always think it’s better to use a 3rd party browser vs the native browser that comes with the operating system or computer.  I have been a big fan of the Firefox browser since it first came out, a separate application install meant security updates to the browser were not tied to the underlying operating system.  In addition, the open source nature, extensions, and plugin support meant there is a open framework for getting problems fixed quick and adding new features relatively simple.

There are two firefox browser additions I want to make people aware of, I use them to minimize the number of ads I see on most websites (sometimes ads lead to some unsafe sites) and the other forces a secure connection to most websites to help prevent network eavesdropping.

  • Ad Block Plus – this addition tells firefox not to load ads from common websites that serve advertisements, it reduces the content on the page.
  • HTTPS Everywhere – this addition from the Electronic Frontier Foundation tells firefox to use a secure connection when logging on to a website if it exists, it helps keep your id and password more secure.

I’m sure there are other security related additions, these are just two I found most useful.

Hope this helps keep your browsing safe!

PodCampAZ 2010

October 25, 2010 Leave a comment

Just a quick plug about PodCampAZ 2010 coming up here on November 20 & 21, a event I will be attending.

I attended PodCampAZ 2009 last year, really by chance.  I had a weekend free and we were already visiting family in the Phoenix area for the Thanksgiving holidays.

Based on reading the website before the event, I figured I’d get a chance to see what the world of new media and social networking looked like since most of my career was spent in data-center technologies.

The event was free, so there was very little to loose other than time, energy, and being away from my kids for a couple days.

The 2 day un-confernece (this is explained on the website) was really amazing, the power of like-minded people coming together to share information and experiences was eye-opening.  I attended presentations on WordPress, Videocasting, Podcasting, and Social Media software.  I also met so many people who were experts in their respective areas.

There is value in the overall socialness of this event and its ability to bring people who want to share, PodCampAZ is a great place to experience & learn from the talent in the Phoenix area first hand.

What is the Epiphan VGA2USB LR?

October 12, 2010 4 comments

I recently purchased a Epiphan VGA2USB LR to record presentation video from workshops where multiple people present during the day.

This device is a frame grabber, it takes the VGA input from the computer and makes images, in fact it makes so many images that one can record video at 30 frames per second depending on the resolution.

I have found this device very nice to use with Camtasia.

The particular things I like are:

  • No software needs to be installed on the presentation laptop (this is huge!)
  • The ability to record what is being presented including software demos and videos (most local sw can’t record wmv video)
  • The ability to record a computer without impacting the computer itself, from a performance point of view (local screen recording can be compute intensive)
  • Can record wireless audio on a separate laptop

Here is how the video part is connected, speaker audio can be input to the recording laptop (Computer in this picture) via USB or Mic input.

Here is a youtube video of recording using the VGA2USB LR and Camtasia:

If you want a in depth review of this little device, check out this blog post by Victor, it even contains a device teardown to see whats inside.

Enjoy!
