An update from last time.

 

I had the same theme for over four years. I’ve made quite a few custom css and PHP edits myself, and it had been outdated for ages… But it served me well.

However, it’s now time for something new.

As always, as minimalistic as possible.

On a side note, this blog has been moved from vm1 (and one before that) a virtual machine running on a dual Xeon 3070 (2.66Ghz) at Databarn to Akama, a VM on an 8 core Xeon E3-1230 (3.2Ghz) at Leaseweb.

HTTPS affects Google Page Rank. Best idea ever. Now read this.

This is the effect, of giving a WiFi hotspot (near a window at traffic lights) two additional SSID; by coincidence the same used by the two biggest local ISPs. You can clearly see when I made the change.

Edit (07/09/2014):

In a couple of lines: how to get FR24 (+ dump1090) to work on your Raspberry Pi.

Be sure to have the right hardware: flightradar24.com/dvbt-stick and … obviously … a RPi.

I got a NooElec from Amazon because I didn’t have the patience to wait for something (that might not work) from AliExpress.

As root:

apt-get update && apt-get install cmake gcc pkg-config libusb-1.0 make git-core libc-dev git clone git://git.osmocom.org/rtl-sdr.git cd rtl-sdr mkdir build cd build cmake ../ -DINSTALL_UDEV_RULES=ON make && make install ldconfig cd ../..

Note to self: <1Gb of RAM on a Dom0 Wheezy server causes kernel panics.

Using 2Gb of RAM seems to do the trick.

More sales…

This time a Nexus 7 (with 3G). This is the first generation, but still running the latest version of Android (Kitkat, 4.4.2 – and rumoured to get the 4.4.3 update soon). It’s the 32Gb version (~27.5Gb of usable space). This device was bought in the US of A, as the 3G version was (or is) not for sale in Europe.

I’m selling it because I don’t have enough use cases for a tablet. It’s great on a plane, it’s great on a train… But I don’t fly as often anymore, and I certainly never take the train. And in many cases I just use my laptop instead (I’m too much of a power user for a tablet, I’m afraid).

Mainly a note for myself, in case I need it again in the future.

And the original blog post is here.

This will turn on a Mac Mini (at least PowerPC arch, not sure about Intel), running Linux, the moment it has power again.

echo ‘server_mode=1’ > /proc/pmu/options

Edit & Note: This option seems to be reset after every boot to. So add it to rc.local or something.

Selling 15ish Flat Panel / Display wall mounts.

These are cheap solutions for hanging displays in the office or at home. We do not use them anymore because our installation company prefers other solutions from Audipack (which are 10 to 15 times more expensive; but are easier and faster to install).

Basically, it’s four screw you can easily drill in a wall (using a paper plan/mold, you know the correct distance depending on your display mounting system). 4 others are screwed in the display, and you then click them together. This is more easily done if you’re two (I don’t encourage doing this alone ;)).

For sale, a used Sennheiser HDR 160 headset.

Good condition, travelled the world with me, battery still is okay. This is not bluetooth, but has a transmitter station (2xAA battery) and thus can be used with anything (including laptop, old stereo, iPod, phone, etc) The headset itself has battery pack included, which is rechargeable.

I’m selling these because my (ex-)employer gave me even better Sennheiser headset the day they fired me. ;)
