Where does Simplenote install on Ubuntu Linux?

I use Simplenote as a note taking application because it works over all my desktop environments.  I just wanted to make Simplenote a start-up application.   It doesn’t seem to get added to the list of applications that Ubuntu knows about and therefore you have to launch it from the command line.

Simplenote is installed at /usr/share/simplenote/ .  To make Simplenote launch at startup open the startup application settings and add the following settings:

Simplenote startup application ubuntu

Bakfeits.nl Cargo Bike Tire Sizes

I was needed to buy some new tyres for my Bakfiets.nl cargo bike.  I couldn’t see the tire sizes on the tire and no-one seems to put the specs on the internet.  After some measuring, I can confirm that the tires are:

  • Front Tires – 20″ x 1.75
  • Rear Tire – 26″ x 1.75

I hope this helps someone.

Bluetooth Really Quiet / Low Volume on Bluetooth iPhone

I have an Audio Pro T10 bluetooth speaker. I use it to play music from my iphone. For some reason this morning, when I tried to use, I could not hear any music coming out. The iphone was connected and playing music. I tried my wife’s phone and this played perfectly. I finally realised that the music was coming through but really quietly at a really low volume.

It seems that you have reset your bluetooth connection. Go into bluetooth setting. Click the information button.


Then forget the device.


Then re-pair the phone with the bluetooth speaker.  The sound should then work again.  If it doesn’t then repeat the process.

OpenSSH Xauth Command Injection Vulnerability – Ubuntu 14.04 – PCI Compliance

I’m just going through PCI Compliance for a company that I work for. The security scan picked an apparent vulnerability in the open-ssh server. The vulnerability had been patched in Ubuntu 14.04 and so this is a false positive. I thought that I post put about it because I found lots of posts where people are trying to compile their the latest open-ssh servers to get around this problem – when in fact it isn’t actually a problems. Compiling your own version of the open-ssh server isn’t recommended because you will have to continually patch the package yourself from then on.

The warning text said:

OpenSSH (OpenBSD Secure Shell) is a set of computer programs providing encrypted communication sessions over a computer network using the SSH protocol.

The sshd server fails to validate user-supplied X11 authentication credentials when establishing an X11 forwarding session. An authenticated user may inject arbitrary xauth commands by sending an x11 channel request that includes a newline character in the x11 cookie.
Please note that Systems with X11Forwarding enabled are affected.

Affected Versions:
OpenSSH versions prior to 7.2p2
An authenticated, remote attacker can exploit this vulnerability to execute arbitrary commands on the targeted system.
Users are advised to upgrade to the latest version of the software available. Refer to OpenSSH 7.2p2 Release Notes for further information.

Following are links for downloading patches to fix the vulnerabilities:

OpenSSH 7.2p2
SSH-2.0-OpenSSH_6.6.1p1 Ubuntu-2ubuntu2.8 detected on port 22 over TCP.

Replacement Bakfiet Spokes

A couple of the spokes where gone on my Bakfiets. I tried all the bike shops in Oxford and none of them stocked the right size.  Bakfiets bikes use especially thick spokes (2.5mm).   The previous owner had replaced the broken spokes with thin spokes and these were essentially useless they could not take the load.

It turns out that the Bakfiets essentially use motorbike / moped bike spokes.  You can order custom spokes in batches of 10 from a company called Central Wheel.  They sound around £2 per spoke.   My bakfiets wheel was a little a small buckle and I didn’t feel confident in replacing the spokes myself and so in the end I took off the wheel and got it rebuilt by Your Spokes.  He measured and ordered the correct spokes from Central Wheel.


You can see how thick the spokes are and also a missing one.

Out of interest, I took the wheel off by resting the bike on an old railway sleeper and tied it to a bin to keep it upright. I’ve also taken the box off because I’m remaking it at the moment.

Replacement or Repairing Bakfiets Buckle Straps

The Bakfiets bikes come with two straps for the children’s bench.   Unfortunately the buckles on my second hand bike had worn out and broken which meant they were completely useless.   The buckles are sewn into the straps and you can’t get replacement straps for the Bakfiets.  Luckily there are fantastic side removable buckles made by a company called Sea To Summit.   They can be used to replace a broken buckle without restitching the strap.

You can order the replacement buckles from Amazon here.

Just Brought A Bakfiet Cargo Bike

I’ve just brought a second hand Bakfiets from a Dutch man in Oxford.  It’s a little different than standard bike.  I’ve found it quite hard to find information about servicing it or even removing the rear wheel… so I’m going to blog the various things that I do to it as I go…

Volvo V50 Losing Fuel Efficiency – Reduce MPG

I have a Volvo V50 1.6 Eco Drive.  Over the passed few months, it has started to lose fuel efficiency dramatically.  It dropped below 52 MPG and ended up around 42 MPG.  It turned out that this is caused by a semi blocked diesel particulate filter.   This was probably blocked because of soot caused by having dirty injectors.  I brought a bottle of DPF Cleaner  and also some Injector Cleaner and added them to the fuel.  I did it over two half full tanks.  I found that the MPG increased dramatically over the period of about 2 weeks.

The other potential diagnosis for this problem is a dirty MAS (Mass Airflow Sensor).  You can get this cleaned also.
