Install Dislin 10.4 on Ubuntu 14.04

Thursday, 15. May 2014

The installation of DISLIN on Ubuntu can be a pain if you do not have some background information. I wrote 2012 a how-to about the installation of Dislin 10.2 on Ubuntu 12.04 (Precise Pangolin). Now Trusty Tahr (Ubuntu 14.04) is out and I updated my how-to.

There are not so many changes but with gfortran 4.8 the option -static-libgfortran works in comparison to Precise and makes your application independent from gfortran. Furthermore the how-to describes how you get rid of the dependency of a Dislin installation. This is nice if you want to share your app with others. You just stuck on the Motif dependency.

Please find the updates in the article “Install Dislin on Ubuntu“.

Using one Lightroom catalog on Mac and PC

Two scenarios will be discussed. The use of a NAS-Server from Synology with its Cloudstation service and just a external hard drive.

netbeans-iconIt is often desired to add a link on a JDialog. E.g. for the application homepage or for a service e-mail.

Tuesday, 1. January 2013

FreeNAS supports the appropriate hardware of the FreeBSD-Version where FreeNAS is based on. But sometimes it is necessary to install a third-party or a self-compiled driver. My how-to “Install Ethernet driver on FreeNAS/NAS4Free (full-install)” shows how to install a downloaded binary Ethernet interface (NIC) driver on a full installation of FreeNAS/NAS4Free. This how-to describes the same for the embedded platform. It was written for non-experienced Unix users.

Restore RSYNC backups of FreeNAS/NAS4Free

Sunday, 2. December 2012

FreeBSD Daemon

In my article “Backup your FreeNAS/NAS4Free shares automatically” I described how to set up automatic backups via RSYNC. To restore a entire backup of a share without altering date, owner and permissions this how-to shows you how.

Finally you just need a single command. In general you can use this command on FreeBSD as well. For GNU/Linux you may need to change just one option.

I have already used this command successfully.

Make Lenovo’s UltraNav Touchpad more sensitive

UltraNav Touchpad und Trackpoint

Lenovo’s UltraNav Touchpad and Trackpoint (Photo: Tim Schulz)

In the Internet you can read here and there that Lenovo’s UltraNav Touchpad do not react as sensitive as some users want. First I was disappointed from a Thinkpad L420′s Touchpad either.

Left and double clicks performed by tapping on the touchpad were not recognized reliably. One-finger scrolling was only possible when I pressed my finger hard on the the pad. And even then it was not recognized in every case. Multi-gestures or even Two-finger scrolling was even more worse.

I had to adjust the sophisticated and extensive settings of the UltraNav touchpad driver to get the touchpad working my way. [...]

Automatic purge of Samba’s recycle bin on FreeNAS/NAS4Free

Last Modified: Jan. 25th, 2013
Saturday, 24. November 2012

Sambas Windows-Papierkorb

Samba can provide a recycle bin on a network share, as current operating systems do locally. Even FreeNAS and NAS4Free offers this feature and can be activated in its administration under Services|CIFS/SMB|Shares.

All deleted files and folders of a share are moved to this bin, physically localized on the network share. In comparison to a Windows’ recycle bin the maximum size is not settable. Therefore the recycle bin is able to overflow the share.

A cronjob and a tiny shell script can prevent this automatically.
