Nebri Automation for Weather Feed to Twitter

In Coding on 2 June 2015 with no comments 39 views

The season was intermittently rainy or dry as I began to take interest in weather. After getting stuck with “If-this-than-that” (IFTTT) for multiple location feeds of weather, I found out that I wasn’t alone, a geek hit the same wall, yet bringing another automation forgery: Nebri OS, an event-driven development platform based-on writing rules in [...]

Any m-by-n Matrix Keypad for Raspberry Pi

In ARM Linux, Coding on 9 February 2014 with no comments 423 views

What about instantiating any m x n matrix keypad by a Python class? Raspberry Pi takes me to learn how to build a Python class for the first time while expanding my initial WiringPi-based matrix keypad into a derivative work. A matrix keypad instance is defined by: Actual GPIO pins used forming the row and [...]

Raspberry Pi: Membrane (Matrix) Keypad as GPIO Input

In ARM Linux on 13 March 2013 with Comments Off 4548 views

Membrane matrix keypad using GPIO as Raspberry Pi input has been my goal since WiringPi deployed in the first place. To begin with, GPIO hacking was initially started with some important basics (see previous post). Without external system (other interfacing chip), the 3×4 membrane keypad reserved all seven GPIO pins plus one pin used for [...]

Raspberry Pi GPIO Input Button Basics

In ARM Linux on 11 March 2013 with no comments 2654 views

When you start hacking Raspberry Pi’s GPIO, first thing to keep in mind is the +3.3V CMOS logic level voltage despite the 5V supply. Secondly, read references about current limiting resistors (eLinux Wiki has a section there). What to avoid then? Try not to physically short the GPIO pin to ground when it is programmed [...]

That Handy Tap Interface on Mac OSX

In Moving to Mac on 4 January 2013 with 1 comment 2513 views

Ubuntu has been my desktop for some years. I’ve become so attached in a way that I no longer know how to work without. Then of course, the pain of moving to Mac is one foreseeable future. Unlike my usual repository where everything is on the table and for free, this one is a little [...]

Alas my LinkedIn password is in the file! (Howto check compromised password)

In Web Apps on 12 June 2012 with no comments 57 views

When LinkedIn privacy breach was about to be revealed during Yuval Ne’eman workshop in Tel Aviv University, suddenly the timeline trends were that of friends, telling people to change LinkedIn password. Both were separate issues and of course the privacy breach was then subsided from people’s attention. To tell you the truth, as a secret [...]

Acknowledging Event: Zabbix Python API

In Coding on 14 May 2012 with no comments 1175 views

Acknowledgement is one of the things that is provided by Zabbix API in its event section. We can make use of the methods get() and acknowledge() to automatically acknowledge an event. Digging through the attributes of those methods, the official doc doesn’t provide complete example to follow. Added with some luck, my search get me [...]

Python 2.6 in Red Hat 5

In General Linux on 14 May 2012 with no comments 22 views

I need Gescheit Zabbix API implementation to run on RHEL5.2 Installing RPMs from Geekymedia seems to be the easiest. I only need the following to make it work: python26-2.6-geekymedia1.i386.rpm python26-libs-2.6-geekymedia1.i386.rpm

Close Low Level Socket in Python

In Coding on 9 February 2012 with no comments 86 views

Important to do in socket programming is to close the socket. Python.org says Close the socket. All future operations on the socket object will fail. The remote end will receive no more data (after queued data is flushed). Sockets are automatically closed when they are garbage-collected. I implemented this low level networking interface for a [...]

Hijri Calendar

In Ubuntu on 16 September 2009 with 1 comment 27 views

Not succeding to find Hijri Calendar in Synaptic, I go for http://www.ojuba.org/wiki/hijra/. First, let Google translate does the job. Secondly, install this python applet. Inside hijra-0.1.18 run $ sudo python setup.py install It’d fail as it couldn’t find HijriApplet. Rename HijriApplet.py to HijriApplet to make it work. Now, it is in path (/usr/bin/) and can [...]
