Correction
In the HowTo article by Jesse Aviles, “Ubuntu For Business & Education – Pt. 3” (Full Circle issue 54, page19), the RPN expressions appear to me to be incorrect, at least when I check them on my HP 12c.
The operators used in the expressions are binary operators, using two inputs (not three) from the stack. For the multiplication operations, they must be done twice to obtain the correct answers:
15 5 div 7 + 20 3 x x = 600 15 5 div 20 3 x x 7 + = 187
I checked the Wiki reference, which confirms this binary nature of the operators.

Mint Menu
I find that some of the strange problems that I've complained about are related to oddities with the Mint menu app. I sure hope that they fix them with Mint 12!
That may well be the source of the problem that LeRoux (FCM#52) mentioned with Office on Wine/Mint 11. If that's the case, he should be able to manually build a shortcut by navigating to the .exe file (it should run from there), and working backwards. I know that the Wine shortcuts do work under Xfce.
Oh, and the login app GDM(?) is hardwired to right handed mice - the source of one of my complaints. I've requested a fix from the developer's list.

Closing Windows
Re: Ubuntu Control Center. “In Ubuntu (Gnome), it’s called Control Center, and in Natty it is installed - but it does not show up in the menus.”
I can see it in 11.10; look on the top bar on the extreme right in the pull-down where you log off. It is the first item.

Ubuntu Youth
The other day I came across Tux Math from Tux4kids. It is an educational game which teaches the kids to calculate. The various levels start with learning the numbers, additions up to 10, 20 100, same with subtraction, multiplication, and division. My 7-year-old son really enjoys the game, so I started to look for more.
This brings me to the topic of this email. It would be nice to have a column for kids. Not only with educational games, but also secure access to the Internet. I remember an article about proxying the Internet access for kids. I will have to check this when the time comes.
I would greatly appreciate such a column, perhaps spontaneously; I'm not looking for this kind of software, but when I read about it I think it could interest my sons.

Thanks for the idea Frank. We used to have an Ubuntu Youth column a couple of years ago, but the writer vanished. Anyone out there want to restart Ubuntu Youth, or start Ubuntu Kids? - Ed.
Primary Age
You asked what we thought was the average age of Ubuntu users was. On reflection, reading your letters, I would say possibly late primary school age to early secondary school age.
I derive this information from the churlish and petty complaints from people who are totally unable to grasp a new technology such as Unity.
Now I thought it was people of my age (in my seventies) who were unable to adapt to change and to adapt to new ideas with technology, rather than young children who are supposed to work it out quicker than us old farts?
I took to Unity as a duck takes to water. And, I have had no problems with it. This is perhaps why I find it so difficult to believe the younger amongst us cannot grasp it?
So what does an old geezer like me use Linux for? Not just for browsing the web and writing occasional letters. I use it for running a newspaper in Norf Lunnon.
We use it for writing articles, for editing photographs, and for sorting out our website using the new version of Drupal content management software.
I use 11.10 in my Netbook already, and will change to 11.10 on my business desktop as soon as it rolls out. You just would not believe the number of programs I use on my 64-bit home desktop - with 8gigs of RAM and three separate 1TB hard drives (two of them external).

MySQL to SQLite
I am not sure if this is the right place to write to you regarding a comment on one of the articles from Full Circle Magazine, Issue55. The article is called How-To Program in Pyton - Part 29, written by Greg Walters. He states there: “A little while ago, I was asked to convert a MySQL database to SQLite. Looking around the web for a quick and easy (and free) solution, I found nothing that worked with the current version of MySQL for me.”
This is not true. I am a Business Intelligence developer and on a daily bases I use ETL tools. I am working with Pentaho Data Integration Tool (Kettle) CE (Community edition) (http://kettle.pentaho.com/). It is a full open source product and it is very mature. It has the ability to transport/transform data from any type of source to any other type of source. The sources can be any type of Database as well as spreadsheets or XML. Of course MySQL and SQLite are among the options. I am currently using the tool in Ubuntu 11.10 and Windows XP. Maybe at some point I could write a how-to article about ETL-ing.

Thanks for the info Rolland, I've passed it along to Greg. And, yes, do feel free to write an article about ETL-ing. - Ed
LTS
In FCM#54, you quoted PC World as saying, “Precise Pangolin … will be Ubuntu's fourth Long Term Support (LTS) release, with a full three years of support.”
In fact, starting with 12.04, desktop LTS releases will be supported for five years. There are some limitations, though; hardware updates will be for the first two years only.
