Generating a CMYK file for printing

So you want to print something (like a banner) but the printers have asked for it to be int the CMYK colorspace? Well we could argue about how to spell colour or whether CMYK is a colorspace at all. But I can’t be bothered, let’s just cut and paste this command which is what I came up with after a morning of hacking… convert -resize 9520 -density 300 rgb_input.pdf +profile icm -profile sRGB_IEC61966-2-1_black_scaled....

Dell U2515H and problems with a USB apple keyboard

UPDATE/Short answer: Use the USB extension lead that came with the keyboard! It has better contacts. Does anyone else ever have problems with this combination? They keyboard just goes dead. I use the monitor’s USB hub to connect my keyboard and mouse. I then connect the hub to either my macbook or my linux pc and toggle the video inputs. Sometimes the keyboard just dies. When it’s in the broken state the following things are true:...

My activities hadn’t been syncing to Dropbox for a while (since mid-November 2014). This activity was not synchronized to the following services: Dropbox: There was a problem indexing your activities on Dropbox, so no activities will be uploaded to Dropbox.

Garmin forerunner 620 verses the 205. The Good, the Bad and the Ugly

I previously had the (very popular) forerunner 205 so this review will be based on comparing it to that. I bought the 205 when it came out in 2006 and it’s still going strong. I love tech though so decided to treat myself to an “upgrade”… The Good Wifi and bluetooth data uploading. This is really handy. Saves getting the computer out. The live tracking is also good, but it requires you to take your phone on your run....

Ugly business practices at Facebook

Facebook have broken its messenger feature into its own app. Lots of people freaked out thinking Facebook wanted to use it to spy on them as it requires excessive permissions etc. In reality, it probably needs all those permissions, I don’t really care about that, privacy died years ago. What bothers me is that people use it instead of emailing me. I strongly prefer email. It’s searchable and owned by me....

Running the 4K AOC U2868PQU and Intel HD4000 graphics…

Ok, I just bought a 4K display, whoop! I knew when I bought it that neither my late-2012 Retina Macbook Pro, or my Ubuntu desktop machine would actually drive the monitor at 4K because they both rely on Intel’s HD4000 graphics which is built into their Ivy bridge CPUs. I did however expect to get at least 2560×1440 (if only at 30Hz) which is fine by me, and then I’m ready when I next upgrade…...
