In Data Centers and Energy I wrote about Hyperscaler Data Centers and Open Compute, and how they bring down the PUE of data centers, making them more efficient, and in Streaming and Energy I followed up on this, explaining how Netflix energy usage fits into this. Now the Uptime Institute has released a study that claims “Data center energy efficiency gains have flattened out”.
So I want to monitor my Jitsi Videobridge to get some useful statistics. The instructions say to enable Videobridge statistics and then grab stuff from port 8080.
A question from Reddit’s /r/mysql:
Als ich noch ein ganz kleiner Kris war, habe ich die Schülerbüchereien von mehreren Schulen durchgelesen und mich dann über die Gemeindebücherei hergemacht. Es ist jetzt mehr als 40 Jahre her, daß ich da im Schülerteam mitgearbeitet habe, aber die Chefin, die damals gerade angefangen hatte und die auch das Schülerteam begründet hat, ist immer noch da und macht ihren Job. Das ist unglaublich großartig.
A question from Reddit’s /r/mysql led to a longer discussion of cursors and how they are implemented in MySQL, and what the advantages and drawbacks are.
I have an embedded Mac mini, it drives the local TV screen by doing OpenVPN to Germany, Netflix, Amazon and the local Subsonic. It does not really do much with the local disk, and it does not need to wake up every hour to make a Time Machine backup over the network.
In an earlier episode I asked for Plugs with Wifi and ended up with Gosund and Tasmota. Considering this to be a success, I asked the Twitters for Temperature and Humidity Sensors. Of course, this got complicated.
(continued from Plugs with Wifi) So the Gosund plugs came, as did the Raspi 4. I did cancel the Shelly plug and decomissioned the TP-Link Kaka, because Tasmota on Gosund is awesome and the Gosund hardware is dirt cheap.
When the Coronacrisis began, a good friend of mine started a Discord server and brought the band back together. As with any of the Coronavirus Quarantine Chats, the initial discussion revolved around baking proper bread. I wanted to archive this, so I needed a way to download Discord chat histories for archive.
I have been pointed at the following question: »Has anyone ever used mySQL events to auto-delete rows from a table after set period? Wondering your experience of doing this.«
So we are baking bread, and for that we have a Wiesheu minimat oven that comes in at a full 16A - supposedly it is using 3kW or more peak plus the condenser hood that comes in at another 500W top power draw. On the other hand, when running the thing is hardly lukewarm, it is running much cooler than the Neff household oven/microwave combo we have.
Let’s have a look at very old database systems. Things like dBase or compatible systems (“xBases”) allowed to manipulate record based files (with indexes) in a procedural way. What does that mean?
A lot of super rich people are currently busy blowing their money into space. Who are these people, and what drives them?
“Hexenmacht” (German Edition) and “Maschinengötter” (German Edition) are part 2 and 3 in the series “Die Krone der Sterne” (The Crown of Stars) by Kai Meyer. See Die Krone der Sterne for a review of part 1.
In the foreword to his short story “With Friends Like These”, Alan Dean Foster writes
It’s Coronavirus Crisis and Netflix is killing us all, again. This time it’s not their excessive energy use, but their dreaded HD videos that are overloading the Internet. Or is it?
So where I work we have a large number of MySQL instances. They are organized in a slightly smaller number of replication hierarchies, which tend to cross region boundaries.
“Normalitär”, ein Begriff, der von @beimwort geprägt wurde. Nach einem Twitter Thread. In seinem Artikel auf T-Online propagiert Schaible eine Bruchlinie innerhalb der “rechten” Parteien, weil Teile der Mitglieder die Weltbildverschiebung der frühen 2000er mitgemacht haben, andere sie ablehnen.
So I wrote about the Sonos Recycle Program before Sonos announced their plans to actively discontinue support for their older Speakers. Back then, the program did make sense, because it was kind of voluntary and avoided sending stuff back to Sonos for a Trade-Up. Even then, people disliked it.
These images are older than time itself. I picked them up while working as a consultant for MySQL AB, but I do not know the source.
