Operating systems

Microsoft announced version 3.5 of Linux Integration Services for Hyper-V. An ISO-image is available for download at Mirosoft's site.

In one of my earlier articles I was wondering if it really matters when Hyper-V indicates the Linux guest status as degraded and tells that an upgrade is required. This version does not change that. Looks like they just added some (weird) new features and improved set of virtulization features for Windows Server 2012 R2, but didn't touch the network code. However, there is a promise of TRIM-support for 2012 R2.

So, the bottom line is: not worth upgrading.

Speedtest.net has pretty much gained The-place-to-test-your-connection-speed -status. It's like Google for doing web searches. There simply is no real competition available.

Mr. Matt Martz (while throwing hot coals) did study their JavaScript-code enough to write their client-API with Python.

The installation into proper directory (recommended: /usr/local/bin/) with proper permissions is this simple:

wget -O speedtest-cli \
 https://raw.github.com/sivel/speedtest-cli/master/speedtest_cli.py
chmod +x speedtest-cli

The built-in automatic detection of nearest server does not work for me very well. Their recommended nearest server is not in the country I live (Finland), but on Russian side. The network connections over their border aren't that good and it simply does not yield reliable measurements. Not to worry, the CLI-version can do following:

speedtest_cli --list | fgrep Finland
864) Nebula Oy (Helsinki, Finland) [204.35 km]

Now that we know the server ID of a proper point, we can do:

speedtest_cli --server 864

It will yield:

Retrieving speedtest.net configuration...
Retrieving speedtest.net server list...

Nice!

Again, thanks Matt for sharing your work with all of us.
