Dnf update problems and how to solve them

25 Nov 2015 pbenavent

One of my workstations runs Fedora for a quite long. I’ve been following practices from my previous technical job and take easy to upgrade the distro or to switch the “lates-what-ever-technology” you would imagine.

I’ve finally adopt dnf command instead of yum to manage the command lines. It has being going well but suddenly I’ve started to received this error message in the terminal:

Traceback (most recent call last):
File "/bin/dnf", line 36, in
main.user_main(sys.argv[1:], exit_code=True
File "/usr/lib/python2.7/site-packages/dnf/cli/main.py", line 185, in user_main
errcode = main(args)
File "/usr/lib/python2.7/site-packages/dnf/cli/main.py", line 84, in main
return _main(base, args)
File "/usr/lib/python2.7/site-packages/dnf/cli/main.py", line 115, in _main
cli.configure(map(ucd, args))
File "/usr/lib/python2.7/site-packages/dnf/cli/cli.py", line 981, in configure
self.optparser.usage = self.optparser.get_usage()
File "/usr/lib/python2.7/site-packages/dnf/cli/option_parser.py", line 255, in get_usage
usage += "%-25s %s\n" % (name, summary)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 40: ordinal not in range(128)

So I decide to go back to the trusty well worker yum.

Finally I’ve found how to solve the problem, by typing this:

  1. export LANG=C
  2. dnf clean all
  3. … and then you may type dnf clean all just is case
  4. Finally, type dnf update and everything must be settled and done, and your system gonna work with dnf or yum, as you wish

Does MS (really) loves Linux?

9 Nov 2015 pbenavent

Microsoft has redefined its targets and keep focus on three main areas:

  • Services
  • Cloud
  • Hardware

Any offer coming from MS may be put it into one of this areas. For instance, what about OS or Office? well, the new Office 365 is a Cloud app and it’s offered as a service.
According to this new approach MS is offering services based on Linux.

Things are so different from a couple of years that they have published a serie named Microsoft Loves Linux.

But don’t get fooled about it, they offer Linux as a service, as an OS built on MS services. So you gonna stay attached to MS.

Monkey, as an icon

Disclaimer: This post is strictly personal and nonsense.
I’ve just realized that I have a soft spot for the monkeys as an icon:

The main question remains unanswered, why do I like monkeys? Probably because we, humans, we are quite more monkeys that we thought about ourselves, aren’t we? Figure out yourself.

Gurú de Base de datos opina sobre Oracle y Facebook

24 Jun 2015 pbenavent

Es difícil mejorar resúmen de la opiniones de Stonebraker que se hace en el post “Stonebraker: la base de datos Oracle está obsoleta y Facebook tiene el mayor problema de datos del mundo” así que lo enlazo e invito a que se lea y felicito a BigDataHispano por el trabajo. Prometen publicar más porque es el principio del artículo original publicado en Barron’s.

Trabajé con bases de datos relacionales, administré servicios ldap (no dejan de ser un almacén de datos jerarquico) por eso me ha interesado el artículo, aunque ahora me dedique profesionalmente a otras tareas (relacionadas con la captación de necesidades de clientes -internos o no- y prescripción de soluciones).

Pero hay más. El titular es un poco más escandaloso que el contenido de sus opinones, sensatas, argumentadas y provenientes de una persona que parece humilde, cualidad poco común hoy.

Las necesidades de acceso a datos actuales no son las mismas y justo por eso aparecen nuevas soluciones para nuevos problemas, BigData, consultas no SQL y sus derivados, análisis de datos con necesidades de cálculo y computación elevadas para poder obtener información relevante de tanto dato recopilado (a veces sin sentido, sin consentimiento y sin propósito previo).
