Replacing a loud fan in my home ZFS NAS

The blue-LED fan I have in my ZFS on Linux NAS is a bit louder than the other fans that I’ve been hoping for. I am going to replace it with a 600rpm fan.

You will notice that I have drilled extra ventilation into the top case panel.

Notice the clear-plastic fan. It is held in with zip ties.

image

Zip tied those SAS cables to tidy them up.

See the 140mm low profile fan on the cpu? Pretty quiet. 120mm 600 rpm exit fan.

image

Let’s snip some zippies!

image image image

Getting the fan power connected is always a chore. My fingers are almost too big.

Fan is now attached and power cables are managed well enough.

image

Trim it up.

image

Plenty of inlet.

Now I put it up on it’s shelf and get it plugged in.

image

and there’s a power switch at the farthest point back there.

image

Alright. Powered up and out of the way.

liftarn_Big_brickSo it turns out you can destroy a windows virtual host really quickly, just by moving it from one host system to another host.

This is something I’ve done with Linux virtual hosts many times, and it seems like an intrinsic way to manage resources.

But not with Windows. They really expect you to take the time to install and configure all your applications again if the motherboard changes. It must not be possible to do live migration of windows virtual hosts.

Parenting and Teaching Programming

At what level of programming are we actually imparting the philosophy of human thought? Or, another way, a basic program that prints out a few numbers is truly trivially basic: it merely teaches some programming syntax. However, contrast your smartphone apps to your old DOS/Windows apps. A significan understanding of human haptics and intuition have been codified into the most basic of smart phone apps where your DOS applications might still be more closely related to punch-cards.

Episode 27 of Bad Voltage takes a fascinating turn in the middle of the episode where these parents stop discussing technology in terms of quantifiable capacities and start talking about the philisophical benefits to young programmers. Jono Bacon quotes a collegue:

Programming is smulating how we thing. Teaching programming is teaching a meta-level of how we [make decisions].

And then Bryan Lunduke chimes in with Scratch, a simple programming environment suitable for younger children.

Please teach your kids, especially your girls, how to code. I firmly believe that this is not just a job skill, but an introduction to logic and analysis that is more tangible than any calculus tought, ever. And don’t brag to me about how you used an interval to compute the average runoff from a forested watershed, you’re showing off. You thouch your phone 120 times a day and you’re entirely dependent on it. If you can boil water and put peanut butter on bread, you can program, so stop raising your hands about how difficult it is. Our children will lead lives where software will decide their salaries, their health insurance, their academic opportunities and how they are promoted and ultimately how they promote themselves through life.

Please listen to that episode and tell me why you are not introducing your kids to computer programming.
