Salted Doorknobs kill MRSA

Salted Doorknobs kill MRSA

Says this article at The Atlantic:

Superbugs like Methicillin-resistant Staphylococcus aureus, or MRSA, have wreaked havoc on the health-care system in recent years. […] How do you stop them? Frequent hand washing is one option, but that requires a behavior change, which can be difficult, even for hospital staff. Another option is to coat those frequently fondled objects most likely to carry the bugs—doorknobs, bed rails, toilet handles—with a special anti-microbial surface, like copper. […] Whitlock found that salt killed off the bug 20 to 30 times faster than the copper did, reducing MRSA levels by 85 percent after 20 seconds, and by 94 percent after a minute.

If you can find Nemo, the reef is already dying

The Atlantic has an article about intact vs. overfished coral reefs.

[L]arge predators both reflect and safeguard the health of coral reefs. If they’re fished out, the rippling consequences can be devastating, leading to fewer fish and sicklier corals. And since those changes happened decades ago, they’ve influenced our perceptions of what coral reefs should look like. We think of the kaleidoscopic realms of Pixar movies or aquarium tanks, but those are reefs that have already been badly depleted. Pristine ones are worlds where predators abound, and colorful prey cower within the coral. “It’s like the difference between the English countryside and the African Serengeti,” […]

New Arrival: How to Kill a City

How to kill a city

Peter Moskowitz has written a book on “Gentrification, Inequality, and the Fight for the Neighborhood”, titled “How to Kill a City”. It’s available on Kindle for some 11 Euro.

There is a matching article in The Atlantic, The Steady Destruction of America’s Cities. Based on observations in Detroit, San Francisco, New York and Post-Katrina New Orleans, he tries to explain the process of Gentrification and distinguish it from urban renewal or other forms of change that are frequent in cities.

While urban renewal, the suburbanization of cities, and other forms of capital creation are relatively easy to spot (a highway built through a neighborhood is a relatively obvious event), gentrification is more discreet, dispersed, and hands-off,” he writes. Moskowitz adds to the growing canon aimed at understanding and explaining the process of gentrification, and he not so subtly suggests that while gentrification  naturally brings some improvements to a city,including more people and money, it also frequently kills some cultural traditions and diversity, the precise characteristics that make cities so dynamic and desirable in the first place.

Ubuntu 12.04 LTS expires next month, but there’s the Dodo club

So Precise Pangolin was published as Ubuntu 12.04 LTS on April 26, 2012.

That’s a long time ago. Back then, Battleship, The Avengers (3D) and Cabin In The Woods (3D) were released. Intel released the Ivy Bridge Microarchitecture. The last proper US president campaigned for his second term and the US weren’t a failed state back then. It was a different world.

Galera vs. Group Replication

Percona: Galera ./. Group Replication

A blog post over at Percona discusses better replication for MySQL and compares Galera and MySQL Group Replication.

Galera builds their own initial state transfer mechanism and their own transaction distribution mechanism, independently of MySQL replication (write set replication wsrep). wsrep is synchronous – on commit, the write set is shipped, applied and acknowledged (or not).

MySQL Group Replication strives to achive the same thing, but uses their own, “MySQL native” set of technologies to do this.

Some basics about distributed databases

This is a replay of a much older blog post, which was available in German language in the old blog. It’s from 2012, and neither GTID nor Galera cluster or Group Replication existed back then.

Wonka> The http://www.toppoint.de probably will never have meaningful load, but I would like to know how one would make this highly available. Some kind of Redundant Array of Inexpensive Databases.

Lalufu> MySQL with replication? Or DRBD?

Isotopp> With DRBD. Not with replication.

The next bond film…

The next Bond is with Gillian Anderson as Bond. And she’s got to neutralize the misogynistic US president, who deserted to the Russians.

Mac mini G4 vs Raspi 3

The Original Mac Mini G4 had a single-core 32-Bit PowerPC CPU at some 1.25 GHz with 512 KB on-chip Cache. It was released in 2005.

It has a Geekbench Score of 766.

 

Raspi 3 by User:Evan-Amos

The Raspberry Pi basically is a a cellphone, without the battery and the packaging. The Raspberry Pi 3 was released in 2016, and has a BCM 2837 with a quadcore ARM with 1.2 GHz.

It has a Geekbench Score of 2128.

In case you need to illustrate how Moore’s Law works, in a practical, touchable way.
