Learn to “Program”

1 Reply

We will use “python”, “ruby” and “swift” as our “programming languages” to “Learn to Program”. Before we begin we will need to check if we have “python” / “ruby” / “swift” already installed on our system. We can do this by typing:

python

or

ruby

If they are NOT, we will need to install. If they are, we will need / want to check the version of “python”.

Once the version is verified, you will want to write your very first python / ruby script. Keeping with tradition, the very first program should be”

  1. Primary Goal / Objective – “Learn to Program” in Python. The emphasis is on “Programming” / “Software Development” and not on “Python”.
  2. Supporting Goal / Objective – Build and Make Available (publicly) an Application Desktop and Mobile (preferably native for both iOS and Android). The purpose of the supporting goal is to

To Learn:

  1. Programming (starting with Python, but the objective is to learn “Programming” not to learn to “Program in Python” ONLY)
  2. Modern Application – Mobile is definitely one of the objective
  3. Publish an App (in the App Store and Marketplace)

Skype Notifications

Leave a reply

We use Skype for our IM needs at work. And I, of course, keep all my devices always logged in – just so that I don’t have to log in every time I move from one device to another.

My frustration is from Skype notifications bombarding ALL of my devices, specially my iPhone, even when I am actively on another device.

When I compare the same issue with my other IM solutions – none of them have this issue.

Update / Upgrade Ubuntu to the “Next Release Version”

Leave a reply

I am now trying to apply the steps to see if I can upgrade from any version of Ubuntu to the next release version. So far I have been able to successfully update from:

  • v11.10
  • v12.04

A couple of times I’ve had to run “dpkg –configure -a” (still trying to figure out what caused that need), but it has worked for the most part so far. My last test / trial is updating from v12.10 to v13.04.

Below is the process (list of steps) I am following (which is what I originally found when I needed to update from v12.04 to v12.10).

=====v12.04 to v12.10=====

Basically followed the post at Unixmen to upgrade my Lenovo ThinkPad to update / upgrade from v12.04 (Precise) to v12.10 (Quantal).

  • sudo apt-get update && sudo apt-get upgrade
  • sudo apt-get install update-manager-core
  • sudo do-release-upgrade -d

I have read reviews that Quantal is “slower” than “Precise”, but I’m not really so much looking for performance issues as compatibility. My Production servers are still running v10.04 and I need to get them up graded to something more recent.

Am expecting to require a re-boot – we’ll see.

Time needed so far – about an hour.

Apache httpd 2.2.3 vs 2.2.14

Leave a reply

[May 9th ’13]

I happen to be working on a project that happens to be migrating from Apache httpd v2.2.3 running on CentOS to Apache httpd v2.2.14 running on Ubuntu

So far, the following are differences I have seen / observed:

  • ServerTokens – OS – DOES NOT EXIST
  • ServerRoot – /etc/httpd – /etc/apache2
  • PidFile – run/httpd.pid – ${APACHE_PID_FILE}
  • Timeout – 120 – 300
  • KeepAlive – Off – On
  • MaxKeepAliveRequests – 100 -100
  • KeepAliveTimeout – 15 -15
  • Listen – 80 – DOES NOT EXIST
  • TypesConfig – /etc/mime.types – DOES NOT EXIST
  • ServerSignature – On – DOES NOT EXIST
  • ScriptAlias /cgi-bin/ “/var/www/cgi-bin/” – DOES NOT EXIST

IfModule – quite diff – need to read / investigate

But these are not really the issue I am having to resolve, my main issue is with FastCGI on the 2 env.

To add more spice to all the above, the app I am working with is written in Lua (which does not have a lot of google solutions out there).
