How to calibrate the screen on a Thinkpad X230 within Linux

If you run Gnome or KDE Plasma as your desktop environment, there are built in tools for you to calibrate your screen. You just need to find an .icm or .icc profile file that matches your screen to calibrate it. (See below to find one that matches the X230 with the IPS screen.) I have run LXDE up to now...

Rethinking my lens setup

There are many reasons to use primes. In the old days, primes had better image quality than zooms. These days, this is sometimes the case, but not always. Another reason to use primes is that you free yourself from having to think about the focal length and by limiting your choices, you have to think more about what you actually...

How the “Ex. Tele Conv.” function on the GX8 can be useful

There is a function called “Ex. Tele Conv.” on the Panasonic Lumix GX8 camera (and probably on most of the other Lumix cameras) that makes it possible to crop an image in camera. I saw it described as “useless” in a discussion on a Flickr group some months ago which seemed at bit harsh to me. Of course, for RAW...

Making sense of Panasonic Lumix camera models

David Thorpe has suggested on his YouTube channel that Panasonic name their cameras with a random password generator. Even if the names of the models are quite cryptic, there seems to be a system to the madness, with cameras organized into different product lines having different letters and different amount of numbers. It also seems like Panasonic has gone from...

Angle of view for micro four thirds prime lenses

Below is a table of angles of view at different focal lengths for Micro Four Thirds prime lenses. Thinking in angle of view is smart, as it makes it easier to know approximately how much you will get into the frame. A tool for measuring angles of the type you would use for a maths class might be helpful if...

Resources for Linux hardware compatibility

Generally, most hardware works quite well with Linux these days, even if it shipped with another OS. (You can be guaranteed a good experience if you buy hardware with Linux pre-installed from Entroware, System76, Dell or Purism.) A lot of hardware has open source drivers available in the Linux kernel or as packages you can install. Some hardware needs proprietary...

What are the advantages of Linux seen from a Mac user’s perspective?

Lately, many Mac users have been disappointed in the hardware and to a lesser degree also the software that Apple makes. It seems like Apple is focused mainly on iOS since their earnings mainly stem from it. Some of the core Mac users in creative industries that have used Macs since the 80s are now leaving or thinking about leaving...

How to scale Firefox to work better on high DPI screens

Sometimes, your OS will scale every app so things look right, but if you have a screen that is quite small and has quite many pixels, but not extremely many, it might work better to have the OS work at 100% and just scale the few programs that need it. This is what I do on my 15 inch laptop,...

Folkeskolens kokebok

Jeg har arvet en bok som jeg tenker kan ha interesse for flere enn meg selv og som jeg derfor gjør tilgjengelig her. Det dreier seg om Folkeskolens kokebok (Lærebok i huslig økonomi I) av Dorothea Christensen og Helga Helgesen. Boken er utgitt i Kristiania av H. Aschehough & co. (W. Nygaard) og dette er sjette opplag av 1916. Jeg...

Ubuntu 14.04 on MacBook 2,1 (late 2006) and how to get iSight working

Ubuntu 14.04 “Trusty Tahr” runs quite well on my MacBook 2,1 from late 2006. Now that security support from Apple is (silently) ended for Mac OS X 10.6 “Snow Leopard”, installing Ubuntu is a good choice if you want the latest software, want to stay secure and don’t rely on Mac-specific programs. (It is possible to dual-boot or keep one...

How to bring Rhythmbox radio streams from one computer to another

I recently installed Ubuntu on a new machine and wanted to bring along my music collection to use with Rhythmbox. This was trivial, I just copied the Music folder from my old machine to my new via an external USB hard drive and let Rhythmbox on the new machine search through the folder at first run. Then I wanted to...

Notation in Telemann’s Sonata for treble viol, TWV 41:G6

Lately, I have been looking a little at a sonata by Telemann for the treble viol in G major from Der getreue Music-Meister. Often, on the treble viol, a practical challenge is that a lot of music is ascending quite high, but in this piece everything keeps moving on the lowest strings in stead. The music actualy descends to c#,...

Things to do to get the most out of Debian Wheezy

I have recently installed Debian Wheezy with LXDE on my netbook. As anticipated, there were a number of things that needed to be done to get it to work as I like. Debian is a bit more work than Ubuntu, but also slightly lighter on resources, and I enjoy learning how to do this stuff. Having used some time to...

How to make alt-tab show windows from all desktops in Lubuntu

I usually keep one or a couple of similar programs running at each desktop. On the Mac, I use 9 Spaces that I alt-tab or ctrl-arrowkey to and from, but when using 4 desktops in LXDE on my netbook, alt-tabbing doesn’t show me all my programs, but only the programs running on the current desktop. Of course, I could alt-scroll...

How to get rid of tap to click in Lubuntu, LXLE, MintPPC, Debian LXDE etc

Tap to click is usually on by default, but I know that I am not the only one that disables it on all my computers to avoid clicking all over the place. In most desktop environments (Unity, MATE, Gnome, KDE..), the Mouse and trackpad system settings panel lets you turn off tap to click, but in LXDE, there is no...

EM’s Quadra pages

I have made some web pages dedicated to the Macintosh Quadra 700 (on the Quadra itself). These contain some technical information about the machine, suitable software, some how-tos and such. Since the pages were written in HTML on the Quadra itself and I wanted to make them readable with System Mac OS 7 and 8 compatible browsers, they do not...
