Here is an updated network map for my home network.

This may change soon as I've decided I need more ports. Since I lost venus (router) I'm short for 12 RJ45 gig ethernet ports. I'm going to wait a while until OpenBSD makes the vpn offload code for octeon stable and then I'm going to buy a 10 GbE switch (probably a Ubiquiti Networks one) and place that in my office, where uranus will go in the hallway and eta in my office. I wasn't going to do that until 2020 but I have a need for more ports now and I don't want to mis-invest. We'll see.

Bavaria's Polizeiaufgabengesetz (PAG)

May 3rd, 2018

Dear reader, I want to make you aware of the Bavarian (a state in Germany) police law that is about to enter if we vote for the CSU or in other words it's leader Markus Söder. The law allows Bavarian police to enter cloud computers of Bavarian citizens and conduct sabotage, spy on the users, embed a trojan etc etc. This is mega bad, and we're facing a possible police state if this law makes it. An article by campact.de which I signed as well sums it up nicely so I want to let you in on it. It's here (german). I don't know why we're seeing all these acts by government to inhibit the citizens rights but it is a global phenomenon. We must act in all democratic countries to fight by democratic means these onslaughts. I already said an article prior to this about Bavaria's Psychiatric law that I won't be voting for the CSU as this crap can't stand. I stand to this.

Cancelled chi.goldflipper.de

May 3rd, 2018

I just cancelled this VPS that I got close to 7 years ago at hetzner online. It was originally called io.solarscale.de, but I renamed it about a year ago when I got goldflipper.de domain. I'm getting a better deal at the same provider with a new vps.

I have just refined the search

May 2nd, 2018

You may have noticed that the "Keyword Search" is gone. Instead I have a "Search" where you can use an AND or an OR search term with up to 16 keywords. So as an example you can search this blog with:

  • "firstname initial. lastname" OR "firstname initial. lastname", and it will list any articles that have any of these exact search terms (case insensitive)
  • something AND something, and if both words appear in an article it will be listed
  • and so on
I'm very glad to make this happen, the code is ugly but it works.

The omega.virgostar.net vps that does primary dns, email and serving this web page was down for about 12 minutes. My provider Vultr has a status page: here. Omega is physically in Frankfurt, Germany.

I have removed PHP from my webserver (for the time being)

April 30th, 2018

Now that my blog is based off C I have removed PHP from this system. There was three other .php files left that I made static content files. This is by some seen as a win. I'm not so sure but willing to see it go through.

A newly written blog, happy anniversary!

April 30th, 2018

Tomorrow is may, and that means that this blog is turning nine (9) years old. For the anniversary I have rewritten this blog from PHP to the C programming language in record time. I think I spent less than 24 hours coding on this. The new blog software is now running and I'm ironing out the bugs as I see them.

Please update your RSS if you've been using RSS. I don't think the url for this will change any time soon so you should be getting the last 10 articles in the RSS. I just renamed my RSS feed to have the history and added the new feed by entering the URL into thunderbird.

Enjoy, and happy may day!

Attention this blog will change

April 28th, 2018

In the last 24 hours I have rewritten this blog in the C programming language. I wrote this with libkcgi, much like the new undeadly blog (which is called fwobac). I even used a routine from Daniel Hartmeier to strip html (function de_html). Anyhow what does this mean to you, the reader of the centroid blog?

If you're using the RSS feed, your feed will stop. The cenrss.php utility won't be ported over. I have written a replacement in C. So you'll quite likely need to restart your feed when the URL changes.

I'm putting this out for May 2018, the 9 year anniversary month of this blog. Nine years ago I wrote this blog in PHP and have been fixing it all along the times when I switched versions of PHP.

Some things have changed. I'm using SHA256 instead of MD5 as the cookies for the commenting system. I'm also heavily pledge()'ing. I've contained the entire cgi in one file and thus had to make some adjustments. It may look minutely different, but just cosmetic changes.

Over the next few days I'm gonna beta test the new blog and the day when I want to put this live will be around May 1st. I can now rest a little as my hands are hurting from typing. I wrote about 1100 lines of C code for this. That's how much the blog is. Anyhow.. cheers!

Ordered 2 more books

April 26th, 2018

I have ordered two books:

  • Perl Pocket Reference - Vromans, Johan
  • Mastering Perl - Foy, Brian D.
Unlike the other books I have ordered these from lehmanns.de not amazon. I'm going to keep amazon purchases low from now on I think.
