Russia introduces new character encoding to replace Unicode

Russian computer scientists have created a new character encoding that will replace Unicode.

The encoding looks like this:

2.SPC! «»%ZV()*+-,./

For Chinese letter, a three-byte-sequence starting with PREFIX-CN can be used. For all other letters, that are not in the base set, an eight byte long sequence starting with PREFIX-OTHER can be used.

This encoding will be mandatory in Russia and all areas annexed by Russia after a transition period.

Programming langauges, internet protocols, databases, operating systems,… everything will be replaced or adapted to work with this new revolutionary encoding.

Goodware: Russian BOT-Networks

The FSB in Russia has an increasing demand for computing power and storage. On the other hand it is getting more difficult to import computers or parts into Russia due to the sanctions.

So now an innovative Russian IT work group has developed a software stack, that allows reliable storage and computing on bot nets.

Some challenges:

  • It is possible that a whole bot net is taken down and all the data is lost
  • Since the confidential data is distributed across millions or billions of nodes all over the world, good encryption is needed all the way
  • Transfer of data needs to be obfuscated

The work group came up with solutions. They develop malware, which is actually called „goodware“, because it serves a good purpose, that installs the software on millions of computers all over the world. This malware is constantly changed and updated, in order to create multiple independent botnets.

The crucial data is encrypted. Advanced Russian technology allows to perform the calculations on encrypted data, so the real content is never revealed on the node.

The FSB-IT-team creates virtual networks, again based on botnets of goodware, with many hops that change rapidly to transfer data and goodware to and from the nodes and to control them.

Data is stored and processed redundantly. Since there is a huge surplus of computing power and storage volume, it is possible to store data with such high multiplicity that recovery is possible even if multiple complete goodware-botnets are taken down.

A positive side effect is that the FSB learns what is going on on the devices where they have positioned their goodware.

So let’s buy more and better computers and help the FSB to get more computing power.

To all my readers:
I am way to upset about the invasion of Ukraine by Russian fascists and the atrocities they are committing there. I am at the moment not able to write useful articles about IT topics.

This is something from mainstream Russian TV by a super star who gets medals of honor from Putin:

I hope that this nightmare can be finished soon and we can invest some of our energy into building positive things. I will come back…

Test systems

Typical software development environments have several systems running the software. While usually each developer runs it on his machine, there is a continuous integration server running and versions of the software that succeed there go to an artifactory and are immediately, during the night or manually installed on a system that is called „staging“, „development“, „dev“, „dev-test“ or something like that. Then it goes to a system called „test“, where the test team can work with it. They only get versions that are actually of interest to them, so it makes sense to separate it from „dev“. When successful, it might go to production, but usually there is just another system, with whatever name, that is supposed to be identical to production and is used for final release tests, before the software actually goes to production.

This kind of works, as long as the software is done by one team. Now we observe cases, where many teams work on the software. They develop their part of the software and kind of need a stable version of everything else. This is especially true for external remote teams.

Now we live in a time where virtual servers are the normal way to work. So getting a new set of servers is no longer an issue of buying hardware, but it is just a matter of running a few scripts. Good organizations can set up whole systems automatically in a matter of minutes. So it should be possible, to just provide within reason a few test systems more when needed and discard them again when done. Abusing an existing system for different purposes rarely works out smoothly.

So it is a good idea to select a technology that allows to setup a system or a whole landscape automatically. This can be virtual servers, docker containers or even physical hardware. It is a lot of work to set this up, but then it becomes easier to add just one more test system to run special tests or to have a stable release to develop against for other teams.
