2010...

2009 is gone, 2010 has started.

Lots of sad news here in Rio, after all the rain that has fallen here over the last few days, but life goes on :(

In just a few days I will officially be on vacation, so I might not have too much time to write here, but I still have some raw material I want to publish, like some experiences with nagios (working very fine here), ntop, cacti, zabbix, etc.

And I'm working on some lay-out changes for my blog, so be prepared to see some novelties here :)

Happy New Year!

Rio 2016

The city where I live - Rio de Janeiro - will host the 2016 Olympic Games.
If you want to see some nice images of the place where I live, check this video:

A year of blogging

It has been a year today I started this blog, so I thought it was about time to change the lay-out a bit.
I made it more-or-less like my homepage, so that people feel, well, "at home" :)

Slackware/Linux/Unix (pre-)history (Part 0: Introduction)

For some time I've been reading texts on the history of Slackware, Linux, UNIX, etc. It all started with this old Slackware version I found and my quest to get this (and several older) versions working in a Virtual Machine on my modern desktop.

I've been using virtualization and emulation for several years, both professionally and for fun.
Searching for even older versions of Slackware and Linux, I found several articles about the history of Slackware, Linux, GNU, Minix, Unix and so forth and started to collect links and making notes to read more.

This collection of notes just continued growing and growing, as part of this history has parallels with my own history in computing. So I decided to write a series of posts about all this, trying to organize my notes in a chronological way. I have no idea how many chapters / parts / posts there will be, as I am still organizing things. Nor do I know how long it will take to finish. It is all really ad-hoc writing.

Talking about all this with my wife she said it might even become a book. Well, she's the one with a talent for writing, but hey, who knows.
After all, I always used this old saying from José Martí (*), that every man ought to do three things before he dies:

• Plant a tree
• Write a book
• Have a son

I already planted a tree and have a son (a daughter as well). But all I wrote until now are software manuals, and I am afraid that doesn't count.

I have no idea if José Martí really ever wrote or said this. I also heard people quoting Ernest Hemingway saying this, but he lived in Cuba for a while, so he might have picked it up there.

(*) José Martí (José Julián Martí Pérez) was a Cuban journalist / diplomat who fought for the independence of Cuba and is considered a national hero there. When I visited Cuba in 1986 I noticed how people still like him.


The national airport of Havana is named after him and he wrote the verses for the famous song "Guantanamera", that in a way might have something to do with me writing these lines:

Yo soy un hombre sincero
De donde crece la palma
Y antes de morirme quiero
Echar mis versos del alma.

which roughly translates to:

I am an an honest man
From where the palm tree grows,
    (well, I do live in Brazil now...)
And I want, before I die,
to cast these verses from my soul
    (now I just hope someone will read all this ;-)

My next post will / should be about the origins of it all: UNIX (but I'll start even before that... UNICS)

To be continued!

Wonders of the internet

The internet is an amazing thing. Sometimes we forget too fast how things used to be before the internet. Yeah, I know, I'm getting old... I started working with computers when there was no such thing as the internet.

Today I was 'Googling' and by coincidence found a page talking about some software I wrote several years ago. It's a simple Hex-editor for Windows written in C, based on much older versions, dating back from the days of CP/M. If you have no idea what CP/M is, you're probably a bit younger than I am ;-)

This version I found today on the internet dates from 2003 / 2004. I published it at the time for free download (I always believed in free software) on my website. I never promoted it too much, but some people managed to find it and at the time I received quite some feedback.

After finding that page, I did a Google search on this Hex Editor and found pages from all over the world mentioning my software :-) Never had any idea my little program has been used in places like Poland, China, etc...

That's the internet: no more distances and complete anonymity.
