4 unix commands I abuse every day

A co-worker watched me type the other day and noticed that I use certain Unix commands for purposes other than they are intended. Yes, I abuse Unix commands. » Tom Limoncelli | everythingsysadmin.com

Solucionado el error "No se pudo abrir el fichero de bloqueo «/var/lock/aptitude»" al actualizar Raspbmc

Tengo una Raspbmc instalada en la Raspberry Pi. Al utilizar aptitude para instalar cualquier paquete o actualizar el sistema, recibo el siguiente error: $ sudo aptitude update [ ERR] Leyendo la información de estado E: No se pudo abrir el fichero de bloqueo "/var/lock/aptitude" - open (2: No existe el fichero o el directorio) W: No se pudo bloquear el fichero de almacén. Esto significa habitualmente que dpkg u otra herramienta apt está instalando paquetes. Se abrirá en modo de sólo lectura, ¡se PERDERÁN todos los cambios que realice al estado de los paquetes! En realidad, lo que sucede es que /var/lock es un enlace simbólico que apunta a /run/lock, que no existe, y de ahí que no lo encuentre. Creando el directorio en cuestión, se soluciona el problema: ...

Solucionado el error "$MFTMirr does not match $MFT (record 0)." al montar una partición NTFS

Si intentamos montar un disco o partición en NTFS, el formato que utiliza Windows, que no ha sido desconectada “de forma segura”, es posible que no podamos montarla y que recibamos el siguiente error: $ sudo mount -t ntfs-3g /dev/sdb1 /media/ntfs $MFTMirr does not match $MFT (record 0). Failed to mount '/dev/sdb1': Error de entrada/salida NTFS is either inconsistent, or there is a hardware fault, or it’s a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details. Incluso si utilizamos el parámetro -o force nos sigue devolviendo el mismo error. ...

The open source technology behind Twitter

Without open source, Twitter wouldn’t exist. Every Tweet you send and receive touches open source software on its journey between computers and mobile devices. We were curious about how much open source is used at Twitter. Beyond that, we wanted to discover how open source may influence the culture at Twitter, Inc. We asked Chris Aniszczyk, Open Source Manager at Twitter, to share the company’s open source story. Aniszczyk will be keynoting at this month’s LinuxCon, August 29 through 31, in San Diego, CA. His topic: The open source technology behind a Tweet. ...

Los dueños de la información II

Hace año y medio que recopilé datos sobre la distribución de la propiedad de los medios de comunicación, compilando esos datos en un solo gráfico: los dueños de la información. Parece que el gráfico tuvo buena acogida y a mucha gente le pareció interesante. A mí, al menos, me parece útil. Una herramienta para tener presente, cuando consultamos algún medio de comunicación, a qué intereses sirve. Así que me puse manos a la obra, recopilando datos de los movimientos empresariales en el sector, para poder mostraros un nuevo gráfico, ampliado, corregido y actualizado. ...

Which Are More Legible: Serif or Sans Serif Typefaces?

Back in 1998 when Times New Roman was still widely used on the web, my then boss made sure we always designed our web sites with Arial, as she hated the look of serif fonts on the web. Was it the case that sans serif fonts were more legible, or was it just a matter of taste? In 2003 as part of my master’s degree I reviewed over 50 empirical studies in typography and found a definitive answer. ...

Tales Of A First Time Driver Developer

Since 2004, I’ve owned a ThinkPad A22m - a laptop that came out in 2001. Much to the dismay of certain friends, I still feel no need to purchase a newer computer. I’ve often said that this old hardware can do everything I need while still letting me run modern software. However, it now seems like I will have to take some responsibility for the code if I want that to still be true in the future. ...

Debian and I

Debian is the most influential Linux distribution ever. Of the 305 active distributions listed on Distrowatch, 147 are derived from Debian, and 87 from Ubuntu, Debian’s most famous off-shoot. In other words, 77% of the distributions being used today wouldn’t exist without Debian. That makes Debian’s nineteenth anniversary on August 16 worth a moment’s reflection, not just technologically, but socially as well. For me, Debian and free software are hopelessly intertwined. While I had played about with Linux before, I only went hardcore when I started work on 5 July, 1999 at Stormix Technologies, an ultimately unsuccessful attempt to commercialize Debian. From there, I jumped ship to work at Progeny Linux System, which was founded by Ian Murdock and funded by Bruce Perens’ short-lived Linux Capital Group, and very much traded on the reputation of the two Debian leaders behind it. ...
