How to create and run MPI projects in CLion

1. Download and install MPI from Microsoft Website. You need to download both msmpisetup.exe and msmpisdk.msi.

Note that you shouldn't have spaces or cyrillic characters in path to MPI installation.

2. Open Windows Terminal and try running mpiexec:

Microsoft MPI Startup Program [Version 10.1.12498.18]

// To find the size of all tables in your Kusto database
find in ( database('<your database name>').* ) where 1 == 1
| summarize total = format_bytes(sum(estimate_data_size(*)))

// Similarly for whole Kusto cluster
find in ( cluster('<your cluster name>').database('*').* ) where 1 == 1
| summarize total = format_bytes(sum(estimate_data_size(*)))

Deezer Keys

Deezer is unique amongst most of the commercial music streaming services I've attempted to reverse engineer in that many keys are stored (obfuscated) on the client side, including the "DRM" used to encrypt tracks. With some reverse engineering effort, this makes it fairly trivial to implement clients and libraries.

Note that many keys and algorithms are implemented in a strange way - often the ASCII hex form of a key or hash is used rather than the raw bytes.

Logging in to Deezer using the mobile API

On the desktop versions of Deezer, logging in requires a Captcha. However, on the mobile versions no Captcha is required. This is because on mobile the app uses a different endpoint to log in, but encrypts the login parameters instead (using a hardcoded key). This details how to obtain the login parameter encryption key (what I call the "gateway key"). The gateway key is a 16 character ASCII uppercase string of numbers and letters.

Note that no keys will be posted here due to fear of DMCA take

Using cec-client on a Raspberry Pi

Most modern HDMI connected devices support Consumer Electronics Control (CEC). It allows devices to send commands to each other, typically to get the TV to switch input and control volume. If you have ever turned on a Game Console and had your TV automatically change input to that device you have seen CEC in action. It is very convenient and useful, sort of a universal remote that works.

Every manufacturer seems to have it’s own branding of CEC (e.g. Samsung Anynet+, LG SimpLink, Sharp Aquos Link) but it may need to be enabled. Check your manual for details.

Using a Raspberry Pi connected to a TV that supports CEC, you can use the command line cec-client application to control the inputs and the TV itself. These are notes on how to use cec-client and understand the different options.
