About Steal

Wed, 30 May 2012 09:16:00 -0700

Steal can only be measured when the VM *wants* to use CPU, but the hypervisor decided to run a different VM. i.e. something like 25% steal means that 25% of the time the vm was doing *nothing* when it really really wanted to do *something*.

QOTD

Fans want to watch their shows. They’ll pay to make that happen. Everything else is mired in entrenched interests. Find a way to make that happen and we’ll all agree that Firefly jumped the shark during its seventh season.

Round Down

Mon, 09 Apr 2012 22:57:13 -0700

Round down,
thinking down,
frown down,
upside down.

Pills down,

sinking down,
goose down.

Arduino 101 #2 - Motor Control

Sun, 06 Nov 2011 03:10:00 -0800

I wanted to play around with controling something throught the Arduino.

This circuit allows you to control the speed of the DC motor via the potentiometer.

Random Notes/Thoughts:

New values from the pot are sent to serial. Nothing is sent if the value doesn't change.
The motor pin is only updated if the value changes. This is probably a useless 'optimization'.
250ms seems like a good sleep time.

Here is the sketch:

And a video of the working circuit

Wow. Just Wow. "Engineering" Fail.

Sat, 23 Apr 2011 13:09:00 -0700

I want to prefix what I'm about to write with 2 statements:

1) Please Amazon get all of these systems back up ASAP. Peoples lives
are in danger.

2) I don't usually like to call out peoples failures, I fail often
enough all by myself. But the post in question compelled me.

With that said...

I saw this link on Hacker News today:
https://forums.aws.amazon.com/thread.jspa?threadID=65649&tstart=0

I read it and was shocked. Horrified even.

3 instances, in the same region.

Monitoring cardiac patients at home.

What came to my mind: WTF WERE YOU THINKING!

Perhaps you should design something a little bit more fault tolerant!?!

And even if you didn't, even if you relied on the reliability of a
single region, why not update DNS and deploy to a different region?

That way you would at least be monitoring those cardiac patients?

I'd really like to find out what company this is so I can make sure
that anyone I know never relies on them.

Ever.

My local dev Mongodb/Redis on OSX

Sat, 08 May 2010 10:51:09 -0700

I'm kind of sick of starting Mongodb and Redis manually in a terminal window and minimizing it to the dock....

So I found these ... http://swig505.com/2010/01/25/launchd-for-redis-mongodb-memcached-kestrel.html

and turned them into...

https://gist.github.com/394651

and

https://gist.github.com/394665

Both of the above assume you've installed redis & mongodb via brew

I hope this helps save someone 5 minutes.

Improvements welcome.

Fog::Vcloud & RSpec Goodness

Fri, 07 May 2010 01:05:26 -0700

http://github.com/freeformz/fog/tree/vcloud

Slightly more Vcloud ...

Switching to Structs (instead of hashes) ... at least for now .. kind
of sick of [] atm. Maybe full classes eventually. Structs are a happy
medium for now.

Mostly testing though.

50 examples, 0 failures

That reminds me ...

If you use rspec ... at all ... Go look at these presentations and absorb.

http://pure-rspec-rubynation.heroku.com/

http://www.slideshare.net/gsterndale/straight-up-rspec

They're awesome.

Trust me.

Thanks to technicalpickles on #rspec for pointing me at them.
