Apache Directory Studio

30 Oct 2009 pbenavent Leave a comment

Thanks to Pedro I’ve been noticed about Apache Directory Studio, which is a subset of a most important project: the Apache Directory and LDAP under the Apache Project.

Thanks to Angel also, I’ve been having a look on that tool. If you want to search, edit and see an LDAP without learn a line about command line, or using ldapmodify plus ldiff files to create or modify entries you should use this tool. Dammed easy.

And you’re in IT probably you have use Eclipse at least once so it would be easy for you since its LDAP editor is a plugin under your Eclipse. You just need to follow this instruccions to get in use as a Eclipse plugin.

Thanks to Pedro & Angel and … great soft again from Apache.

How to know my own PID in a bash shellscript

5 Oct 2009 pbenavent Leave a comment

I was sure there’s a way to know easily what is the PID in a bash shellscript, without doing anything complicated -such a ps wwaux | grep something– and then I’ve found this quick ref. about less easily guessed commands and codes in Unix shell

By the way, inside a shellscript, the PID of that shellscript is stored in the $$ environment variable, for instance, you may type this on your terminal:
echo "My pid is $$"
and you’ll get something like:
My pid is 14467

Delete a line with sed

2 Oct 2009 pbenavent Leave a comment

I wrote about how append a new line using sed. Now let me copy here how to erase or delete a line using sed if that line has a pattern.

If you want to erase, for instance a line that starts with # character, you should use something like:
sed -e '/^#/d'

If your text comes from a command you may use a pipe by doing something like:

cat /etc/services | sed -e '/^#/d'

or if you want to use on a certain file:

sed -e '/^#/d' fileName.ext
Hope it helps someone…

Friends of my friends

22 Jul 2009 pbenavent Leave a comment

As Nop has wrotte friends of my friends are not (necessarily) my friends, for sure you may compose an acronym imitating FOF but this is too geek even for me.

Nop says that he receives a lot of Facebook requests for getting in touch with people who is friend of somebody else and not known by himself. (Do I wrotte properly this sentence? … never know…) He also says that this social-networks are not social but unsocial… and I agree… as long as you use those networks you don’t get in touch in real world, what is more social than the real world relationship?

I’ve been in Facebook but I’m no longer, it is very time consuming and very often it tries to access to personal data or such things. I’m even considering how useful is LinkedIn or Xing.

In my humble opinion it is true that network is changing a lot how our world is, but sometimes, we believe that everything comming from the Internet has a positive touch: we shouldn’t loose our critical point of view… neve.

Some thoughts about IBM plans to buy Sun

21 Mar 2009 pbenavent Leave a comment

This days there’s some buzz about IBM plans to buy SUN, it really doesn’t affect a poor boy such me but just for fun I was thinking about it.

The golden egg is Java. I have no idea about how many chances offers to IBM to get Java under its umbrella, you simply consider that one of the main IBM products is its WebSphere. You may also think about how competitors will stay by a Java under IBM controls while they also has its owns Java servers.

Minors things to consider:

  • Eclipse, now with IBM and no code suite in Sun to compete with,
  • MySql, bought by Sun, how MySql stays under this new map?
  • Solaris, with an OpenSolaris and a commercial Solaris, how it remains in IBM’s portfolio, side by side with Aix, AS …
  • Oracle data base, and others software products runs over Solaris, how does it end with Solaris under IBM control?
