OMG, our cybervaccines are failing

Dark Reading is scared: All new malware is “zero-day”, for an interesting and wrong definition of zero-day, because then the article reads much more impressive.

The actual definition of a Zero Day is a previously unknown exploit that is being used by some party to compromise a machine. In the article, the term is used differently, meaning a file that is a known malware, but has changed itself so that it has a checksum that is not in currently distributed signature catalogs of known malware.

That is of course neither correct, nor new.

Fake News Fact Checker “Focus Online” – seriously?

In the campaign against “Fake News”, Facebook is looking for fact checking partners. Der Spiegel reports (article in German) that besides Correctiv.org so far no other proposed partners have been willing, so they are now further down the list, talking to… Focus Online.

How far down the list is Focus Online? Well, check yourself: Anti-Euro Article from 6-Feb-2017 by Bernd Lucke.

Next in line are probably the Kopp-Verlag and the independent action group for more media truth about the KKK.

FOSDEM: The coming Radio Lockdown

The European Radio Equipment Directive requires all devices that are able to send and receive radio signals to be locked down. Without further specification of exceptions, which has not yet been done, this will affect all devices, including pure receivers such as GPS receivers and car radios, but also mobile phones and amateur radio operators and of course almost all Internet of Trash (IoT) devices.

Hardware manufacturers are required to “install technical measurements to protect the devices from being flashed with ‘non-compliant software'”.

The talk by Max Mehl is available on the FOSDEM site.

Containers 101

It is helpful to remember that containers are just normal Unix processes with two special tricks.

Normal Unix Processes

Unix starts processes by performing a fork() system call to create a new child process. The child process still contains the same program as the parent process, so the parent processes program still has control over the child. It usually performs a number of operations within the context of the new child, preparing the environment for the new program, from within.

PID 17 forks, and creates a new process with PID 18. This process executes a copy of the original program.

Then, after the environment is complete, the parent program within the child processes context replaces itself by calling execve(). This system call unloads the current program in a process and reuses the process to load a new program into it.

Load, Load Testing and Benchmarking

(In order to be able to give up the test blog at blogspot.nl, I am moving content over)

So you have a new system and want to know what the load limits are. For that you want to run a benchmark.

Basic Benchmarking

The main plan looks like this:

The basic idea: Find a box, offer load, see what happens, learn.

You grab a box and find a method to generate load. Eventually the box will be fully loaded and you will notice this somehow.

An Energy Storage Market develops

Renewable Energy World reports in an article titled “Energy Storage Market Outlook 2017” on exactly this subject.

Currently there is not overly much available in terms of capacity in an Energy Storage Market, but what is there is growing very fast, with a forcast of 30GW new installation through the year of 2020, and a compount annual growth rate of 60%.

For the near future, the dominant form of energy storage, pumped hydropower, is sure to remain the principal method of storing energy, occupying a global market share of over 95 percent. Aside from pumped hydro, a plethora of energy storage technologies exist with a growing number of new solutions being tried, tested and installed on a commercial basis. An even larger number reside anywhere between blueprint designs and various levels of research and development.
Going forward, battery storage — of the lithium-ion variety — is expected to retain its majority market share, according to Roberts.
