To completely disable WiFi and Bluetooth by disabling kernel modules in Raspbian / OSMC add following lines to
When you disable RAM caching by setting “cachemembuffersize = 0” in .kodi/userdata/advancedsettings.xml Kodi will write video cache to disk.
Video cache will be written to kodi temporary folder:
Raspberry Pi manufacturer has stated that you don’t need heatsink for the normal operation of the Raspberry Pi device, however overclocked or heavily stressed devices will benefit from heatsink installation.
I decided to compare available heatsinks on the market and have found the best heatsink for Raspberry Pi 3.
First tested heatsink is small – 14x14x6mm, priced 1$ on Ebay
It has an adhesive layer for mounting on CPU.
Second heatsink – is larger 50x25x10mm, also priced 1$
Mounting was done with Arctic Silver thermal compound and super-glue 🙂 Thermal compound was applied to the center and glue – to the corners of the chip.
Please note that this will be a permanent solution, and you will not be able to remove the heatsink.
For loading the CPU I used stress software (apt-get install stress).
Only 1 core of Raspberry Pi 3 was loaded – frequencies: arm_freq=1290 core_freq=430
Here are the temperature graphs:
Red line – no heatsink.
Blue – small heatsink 14х14
Green – large heatsink 50х25
For a price of 1$ you can greatly improve temperature of Raspberry Pi 3 – by 8 degrees in idle state and by 13 degrees under moderate load.
If you need specific version of vc_redist.x64.exe you can find 14.0.24215 here:
While upgrading MySQL server on centos 6 from 5.5 to 5.7 you may encounter following error:
Transaction Check Error:
file /usr/lib64/mysql/libmysqlclient.so.16.0.0 from install of mysql-community-libs-compat-5.7.11-1.el6.x86_64 conflicts with file from package compat-mysql51-5.1.54-1.el6.remi.x86_64
file /usr/lib64/mysql/libmysqlclient_r.so.16.0.0 from install of mysql-community-libs-compat-5.7.11-1.el6.x86_64 conflicts with file from package compat-mysql51-5.1.54-1.el6.remi.x86_64
It can be resolved by running following yum transaction:
$ yum shell
> remove compat-mysql51
> install mysql-community-libs-compat
This will update affected mysql libraries to newer version without breaking any dependencies.
