Database Power Savings

I think this is a pretty amusing tidbit. A few weeks ago I noticed a MySQL database taking a little more CPU than expected. Nothing dramatic. This is a small VM on a host running several and as the graph shows it doesn’t even break 25% capacity.

After about an hour I was able to reduce the CPU consumption considerably by updating, making sure indexes were optimal etc. etc. Nothing incredibly dramatic. Hardly a herculean task.

Now a week later I can clearly see the power consumption dropped a little bit on this particular host as a result of my optimization work.

Just goes to show, even if you run stuff in house and have extra computational power handy, it can add up.

1W of electricity @ $0.17 running 24 x 7 x 365 = $1.50/year. Literally a measurable improvement.

Fireworks From Jersey City Waterfront

Due to a beached whale, state parks were closed this weekend and the annual fireworks were moved from Liberty State Park to what I consider the superior waterfront location (it’s easier to get in/out on foot).

Not to bad photo wise.

Best solution I’ve got for when Docker fills up your hard drive. I think I named this cronjob correctly.

Apple Suspects Hardware Espionage

From 9to5Mac:

At least part of the driver for this is to ensure that the servers are secure. Apple has long suspected that servers it ordered from the traditional supply chain were intercepted during shipping, with additional chips and firmware added to them by unknown third parties in order to make them vulnerable to infiltration, according to a person familiar with the matter. At one point, Apple even assigned people to take photographs of motherboards and annotate the function of each chip, explaining why it was supposed to be there. Building its own servers with motherboards it designed would be the most surefire way for Apple to prevent unauthorized snooping via extra chips.

I can’t say this is terribly surprising. There’s been reports of this sort of thing happening to Cisco hardware among others.

Grace Hopper For #TheNew10 Dollar Bill

Grace Hopper
Since the Treasury Department announced they will be redesigning the $10 bill and featuring a woman on the front, it got me thinking. While more obscure, Grace Hopper is the ideal candidate.

Lets go through her qualifications:

  • Attained the rank of United States Navy rear admiral. A rare feat for a woman (the first was Alene Duerk).
  • Active in the service between 1943–1966, 1967–1971, 1972–1986 for a total of approx. 41 years of service. Including during WWII.
  • Notable achievements in her field had a large influence on shaping the her industry as well as the nation as high level programming languages accelerated computer proliferation through business and eventually personal use:
    • Wrote the first compiler.
    • Invented COBOL, which is still in use over 50 years later and it’s predecessor .
  • She’s the one responsible for the term “bug” being used to describe a defect in software.
  • Responsible for some badass quotes like “It’s easier to ask forgiveness than it is to get permission.”
  • And lastly… diseased (technically relevant).

Per the Treasury Dept. website:

…The person should be iconic and have made a significant contribution to — or impact on — protecting the freedoms on which our nation was founded.

I think a Navy veteran buried in Arlington National Cemetery with full military honors meets the qualifications as much as anyone who walked the face of this earth.

So to summarize, she’s a female veteran who climbed the ranks of the Navy who quite literally invented her field and launched and industry that’s reshaping her country and the world even years after she passed away. I’d say that’s worth $10.

Planet or not, roughly 100 years after the first powered flight, we’ve sent a vehicle equipped with a camera to Pluto to take pictures and wirelessly transmit them back. That’s nothing short of amazing.
