stfn's questions

Last week I replaced my Ryzen 5 1600 with a Ryzen 5 2400G. Since then I'm struggling to get the GPU working.

I've tried 16.04.3 vanilla with HWE-kernel 4.13. It works out-of-the-box, but without hardware acceleration / OpenCL (ROCm) support. I've installed the latest amdgpu-pro driver amdgpu-pro-17.50-511655 from 17-12-2017. My system won't boot with it, it hangs after entering my fulldisk encryption password.

I've also tried with the 4.15.4 and 4.16-rc1 kernel, but the AMD driver doesn't build with that kernels.

For what I've read, ROCm support for Raven Ridge doesn't exist yet.

I must say, I'm a little disappointed with AMD that they release hardware without proper software support. My APU is kinda useless now.

I wanted to install Landscape on my Ubuntu 16.04 LTS server, just to found out it isn't supported yet.

I looked around on the www but didn't find an ETA. Only a reference that it should be released in a few weeks (posted 17 April): https://askubuntu.com/a/758418/67290.

Who can give me an ETA or knows a mailinglist where I can sign up to let me know when a new version of Landscape is released?

I'd recently upgraded my Ubuntu 11.10 x64 server to 12.04. In this process Squid was updated from 2.7 to 3.1. Squid 3.1 has many different options witch broke my setup. So I completely removed squid 2.7 and 3.1 and started from scratch. Everything is now working as before except for 1 thing: caching of .swf files with ?/variables. Squid 3 sees a ? as dynamic content and does not cache it.

For example, Squid 2.7 was caching the .swf file at http://ninjakiwi.com/Games/Tower-Defense/Play/Bloons-Tower-Defense-5.html and 3.1 is not.

<object id="mov" name="movn" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="800" height="620">
  <param name="movie" value="http://www.ninjakiwifiles.com/Games/gameswfs/btd5.swf?v=160512-2">
  <param name="allowscriptaccess" value="always">
  <param name="bgcolor" value="#000000">
  <param name="flashvars" value="file=http://www.ninjakiwifiles.com/Games/gameswfs/btd5-dat.swf?v=280512">
    <p>Get Flash play Ninja Kiwi games.</p>
</object>

It is because of the "?v=160512-2" and "?v=280512" part. This line should be responsible for that:

refresh_pattern -i (/cgi-bin/|\?) 0    0%      0

But disabling it still doesn't cache the .swf files.

How do I configure Squid 3.1 to cache those files?

My current config is:
