Protecting MySQL Network Traffic

Percona Live Talk by Daniël van Eeden: Protecting MySQL Network Traffic.

Warning: It is somewhat more complicated than this:

Slideshare

Check out the performance slide (#22), too.

Tl;Dr: You want a MySQL compiled against OpenSSL, because SSL Tickets and AES-NI support. YaSSL sucks, hard. With Tickets and hardware symmetric encryption, TLS support in MySQL is actually no longer slow.

Tl;DR 2: MariaDB is actually pretty well positioned here.

Optane/Xpoint and paradigm shift

So Optane is here. It’s a bit-addressable non-volatile storage with a higher density than DRAM. It’s not as good as initially promised, yet, but it’s a first iteration.

It is basically very slow RAM (or very fast flash), which is bit-adressable. So you are not, like with flash, erasing 64 KB sized pages, but you are doing things to individual bits and bytes.

It’s also faster than flash (but slower than DRAM), about 10x faster than old Commodore 64 memory.

And it’s persistent, so if you power off your machine, contents are not gone.

And it is very dense, denser even than the memory you currently use, because no transistors, so less space necessary per bit.

This is going to change a lot of things, but not right now. We need to rethink our approach to persistence.

Deutsche See is buying Streetscooter, denounces Volkswagen

Automobilwoche (Article in German) reports that the German fish company Deutsche See is going to buy 80 streetscooters from Deutsche Post. That will make them the first customer of the electric delivery cars produced by Deutsche Post.

Deutsche Post originally had urban electric delivery cars built by a startup in Aachen, later bought that startup, so they are now making these cars for themselves. Recently Deutsche Post announced to also sell the cars to third parties and expand the model palette upwards and downwards to electrically powered delivery bicycles. They are going to make up to 20.000 vehicles this year.

Deutsche See is being quoted: “Volkswagen couldn’t and wouldn’t deliver an electrical utility vehicle solution within a ten years timeframe.” They also have an 11.9 million Euro lawsuit against Volkswagen going, because they feel being defrauded by Dieselgate after purchasing Diesel vehicles with Blue Motion technology.

Kim Stanley Robinson: New York 2140

New in the SUB: Kim Stanley Robinson imagines a submerged New York in the year 2140.

After the sea level rose in multiple increments of three meters, the world change, and so did New York. It didn’t die, though. It just changed. Told from the viewpoint of different characters with differing levels of privilege and different interests, the real star of the story is the City.

Whatever became of… Shirtstorm?

In our section “Ist ja bald Weihnachten…” we are looking at the Shirtstorm. It was in November 2014, when Dr. Matt Taylor was celebrating the Rosetta Mission success by wearing a special T-Shirt that his friend Ellie Prizeman made for him.

People not knowing him, or Ellie Prizeman took offense and Taylor was forced needlessly to apologize. The entire affair is know as Shirtstorm.
