Migrating Contacts over phones

-
Recently I was helping in a cell phone migration; contacts were the most important thing to migrate, but the devices where not directly compatible as the devices where a Nokia and a Samsung.

After a couple of Google’s searches, I got to the idea that there were no application so make my life easier, so I got to the task to investigate what the vendor’s applications were capable of.

I install in a Windows PC both suites, Nokia PC Suite and Samsung PC Studio, after I connect and synchronize both devices I got the option of exporting and importing contacts.

From the Nokia PC Suite, I exported all contacts; as a result I got a single file including all the 100+ contacts. I then turn to Samsung’s suite and try to import from the file, but it only imports the first one.

I don’t know if it has something to do with the vCard standard, but, most of the products I´ve tried do the same when reading multiple cards within a file.

So, next thing to do was to create as many files as contacts to import, wait a minute, this is more than 100 files!

What if I want to make a migration of a device with thousand of contacts?

To make my life easier, I start creating a DOS shell script to separate the file in as many contacts as is has. Its operation will be easy:
1. Read source file line by line
2. When detects the tag “BEGIN:VCARD” create a new file
3. Writes all read lines to the created file

Whit this simple process I got all the files I need and next step was to imported in Samsung’s suite. Fortunately, it support to drag-n-drop many files at a time, so, just in a moment the Agenda was introduced in the new phone.

Here is the code to create the vCards.

It reads the input file in the same path. File with contacts need to be named as “contacts.txt”


@echo off

set fileNumber=0

setLocal EnableDelayedExpansion
for /f "tokens=* delims==" %%a in ('type contacts.txt') do (
if "BEGIN:VCARD" == "%%a" (
set /a fileNumber+=1
echo BEGIN:VCARD > !fileNumber!.vcf
)
if NOT "BEGIN:VCARD" == "%%a" (
echo %%a >> !fileNumber!.vcf
)
)

goto :eof


Here you can find a copy of the script in case you want to test it yourself: readCards.zip

Before college

My father spent many years as a Teacher in the Universidad Regiomontana (also see this ) and he made an arrangement with computer lab to let me go and “practice” with the computers they had a t that time. I spent many hours, when the lab was free, programming in basic and playing in those computers. A game I remember is Karateka ; at that time I was at High School and was taking some Karate classes of ShitoKai and that game took my attention. At high school we had classes of BASIC , I previously used BASIC for my First big program, so this course was not quite exceptional for me, but I took some practice with the programs I created.

iPhone and the copy and paste programming

-
I was reading this post: Resize a UIImage the right way where is mentioned the copy and paste programming . I agree this is a big problem when downloading code from the web without testing, but, copy and paste make things easier when developing similar functionality. The existence of code libraries makes us copy and paste code snippets to reproduce functionality. Programs in the big picture are different, but in its internal functionality are similar. Database access is “barely” the same and don’t make sense to rewrite all the database access code, it is easier (and practical) to copy that code from a library or other sample we previously create. At the bottom line, I really like the article and support copy and paste programming when doing the right way.

Initial development courses

-
At college we had 4 courses for development, those where more focused for us to had Language knowledge. Those classes were Pascal , GW-BASIC , COBOL and FoxPro , in that order. Programming Logic was an issue in those times as classes where focus to the language and not to the logic; also, not all of us had a computer at home, so, we had to visit the Lab for computer time. Time might not be too expensive, but availability was another issue. At Pascal course, I had some problems with coding as I as to create big programs, most of them long IF Statements and the following of my core was hard to other persons, I took little attention to this issue until tow more courses. In a midterm exam, my teacher, Engineer Diana Margarita (Diana Margarita is guilty of my carrer), gave me a low grade for my code, I had to type it in the PC and show her the result to reconsider my grade. Second course was GW-BASI, this course was given by Engineer Danilo, he had a “different” way to teach, but was
