Windows PC not auto-booting?

Since I installed the “Windows 10 Fall Creators Update”, build 16299, the desktop has stopped auto-starting, to it’s BIOS configured schedule. It’s scheduled for a 5:01am start, but every morning I’ve come into the room, since the update, it’s sitting there switched off.

A couple of Google’s later and here’s the answer, well I hope it is as I haven’t verified it yet, something for tomorrow morning. So the suggestion is to disable Windows “fast startup” mode, details on doing that can be found over at TechAdvisor.co.uk, and a more detailed explaination of why is at HowToGeek.com.

29th October 2017: Seems to have resolved the issue.

Cannot synchronise MLAT with Piaware?

Possibly an issue with Pi firmware of 4.9.x, find out your version by using this command

uname -a

If so then issue these commands, the first installs the firmware updater the second the 4.4.50 version of the firmware.

sudo apt-get install rpi-update
sudo rpi-update 52241088c1da59a359110d39c1875cda56496764

If you can’t install the firmware because you have a “custom” kernel then you’ll have to get the latest version of Raspbian and install that, then run the above two commands.

Reducing wear on your sd-card

One way to increase the lifespan, and presumably, reliability of the sd-card, currently being hammered, in your Pi is to put some of the temporary files into memory.

Add the following to your /etc/fstab

tmpfs /var/log tmpfs nodev,nosuid,size=50M 0 0

If the size isn’t specified then half of the machine’s memory is used.
nodev and nosuid are security options, the suggestion is that these only need setting for public facing machines.

 

8-Jan-2018: If you’re using the lighttpd web server then be aware that it stores files in /var/log, and it doesn’t like them being removed. This will cause the server to fail to start.

How to stop Google using your SSID for location services

Just found out that you can stop this.

By default, Google, and possibly others, use your SSID to help improve their location services. You can opt out by changing your SSID, shouldn’t it be if you want to opt in? Anyway if you add “_nomap” then they won’t record your data, alternatively maybe hiding the SSID does the same?

Dell Optiplex 755 turns itself on for a seconds randomly throughout the day

Sound familiar? Tried updating the BIOS and no joy, turned of power management?
Then try this from the Dell forums: OptiPlex 755 mysteriously turns itself on.
Search for MEBx in the thread, default password for MEBx is “admin”. The new password has to be at least eight characters, have one uppercase letter, one numeric and one special.
And then you need to go into the “ME Power Control”, under the “ME Configuration” menu and ensure that “ON in S0” is set as the default, which means only use ME when the machine is switched on. What you probably have, if you’re reading this, is “ON in S0, S3/AC, S4-5/AC”. It’s the “S4-5/AC” setting that causes the machine to power cycle the fans as “S5” means the machine is switched off.
Have a read of the full MEBx article on Dell’s site – IntelĀ® Management Engine BIOS Extension (MEBx).

Windows Live Messenger looks fuzzy or out of focus?

If so and you’re running an ATi AMD graphics card try this:

I’ve just experienced the same problem. It was caused by installing the ATI 11.5 Catalyst driver update from Windows Update.

To resolve it open Catalyst Control Center, goto the “Gaming” section and untick the top checkbox “Morphological filtering”.

Apply those settings and then restart Windows Live (making sure the process is actually stopped in task manager before starting it)

The quote comes from Windows Client > Windows 7 IT Pro Forums. It’s still an issue with the 12.8 Catalyst drivers as I’ve just encountered it.
