I really like the idea of tracking issues inline as part of your project's documentation:
https://medium.com/@MrJamesFisher/documentation-for-free-ec6d50f2b3c2

For the longest time, I've been using Jira and github task and issue tracking to organize development effort.

[ ] - find the changelog interview with the founder of gitlab.com -- covers issue tracking and workflow management.

I use agile sprint planning to help with longer term company roadmaping of my work. This is often messy though, as it's common to create issues and and add them into the sprint. I like the idea of just working off of a prioritized backlog at least.

I could see this wiki-style issue tracking actually work if there were proper tooling in place with the wiki software.

It's possible to write mysql queries that join tables from multiple databases.
[ ] - add a link to the mysql docs for this cross database join feature

Because queries do not span multiple database server connections, it is not possible to join databases across multiple servers.

Enter MySQL proxy....

• If so, is it possible to perform cross database joins where those databases are deployed across servers?

I saw Dropcam and fell in love. But with the idea, not their proprietary offering.

I recently purchased my first home and ADT sales staff are worse than mosquitoes. For $50 a month I could have the house monitored "professionally", or I could rig something up myself for a one time up front investment. I setup Motion on an old laptop (more on that below) which was easy enough, but figured there had to be a better open source way to cover more of the house (and outside as well) without breaking the bank and getting sucked into expensive subscriptions.

I also just rescued Sammie from a dog shelter and am still house breaking her, so it's ideal to be able to see how she's doing without having to drive home from work multiple times a day. Dropcam and Simplicam both have a two way audio com feature that would be nice to replicate.

So I started researching on social media and all of my progress really started here:
https://twitter.com/yibi/status/481462671221719040

Dropcam

features:

• event notification on your phone
• record to the cloud
• event detection disregard learning

Dropcam is pretty much a plug and play solution. It comes at a cost though. $150 for the cheaper offering and $200 for the "higher end" camera.

Simplicam

features:

• very close to the Dropcam offering
• only one camera available: better specs than Dropcam's entry-level offering but not as good as Dropcam's Pro camera
• offers a $50 /yr 1 day record feature subscription (cheaper than Dropcam's minimum 7 days recording subscription at $99)

DIY options

• ZoneMinder - http://www.zoneminder.com
• Motion - http://motion.sourceforge.net/

ZoneMinder

• this is probably the most mature alternative to professionally installed full scale home security solutions
• docker containers already available: https://registry.hub.docker.com/search?q=zoneminder&searchfield=

Motion

• This is what I've been using (on an old laptop with a built-in webcam) and is probably the easiest to setup.
• Detects events by calculating a pixel delta score from frame to frame. Motion saves still images above sensitivity score you specify.
• Motion saves the images to a folder on the machine which I've configured dropbox to sync.
• I have an IFTTT recipe that runs when dropbox syncs a new file. This serves as my notification of an event picked up by the system.

[ ] does Motion support IP cameras?

How low can you go? Who provides the best of the cheap hosting space?

• they have the same price points

• tie in a performance monitoring solution
• compare the performance to DigitalOcean at the same price point

[ ] - what distinguishes vultr as a good hosting provider? How do they stack up with the "more mature" DigitalOcean?

• how old is digital ocean
• how old is vultr?

[ ] - what kind of support do these providers offer?

[ ] - how do these providers stack up against bigger names like Rackspace, Amazon, Microsoft, and Google?

Replication:

Benefits of replication for this situation:

I bought a pair of Logitech Z263 THX 2.1 speakers some 3 years ago, and they finally gave out on me today.

Monoprice

I've bought all kinds of cables from Monoprice for a long time now. I still haven't tried out any other products they sell though. Before spending money on their $250 5.1 surround sound system, I figured I would run a cheap experiment and replace my office speakers that just died.

I decided to kick things off with the 8" 3-way bookshelf speakers:

https://www.monoprice.com/Product?c_id=109&cp_id=10904&cs_id=1090407&p_id=8251&seq=1&format=2

I've heard great things about these little amps:

http://www.amazon.com/Lepai-LP-2020A-Tripath-Class-T-Amplifier/dp/B0049P6OTI/ref=sr_1_1?s=electronics&ie=UTF8&qid=1414904333&sr=1-1&keywords=Lepai

Don't forget the wires! Don't do what I did and forget to buy the speaker wire...

The hardware is starting to grow on me. The metal on the sides of the screen seems like it doesn't fit around the glass as well as it should.

The device performance is great. It started out slow (while I a TON of updates were pulling in the background), but sped up pretty quickly and is a better experience than my iPad Air that I think I'll be selling soon.

I didn't go for the LTE but I'm already kind of kicking myself wishing that I had. I can definitely see using this over my iPad Air.

The downsides... Apple has a default split keyboard in landscape mode, where android does not. There are some after market keyboards that do offer this though, so I'm going to keep trying them out to see which one works best for me.

• Beats by Dre Tour - I'm not a big fan of heavy in-ear headphones
  ** Good at the desk only: they kept falling out of my ear while on the treadmill
• Bose headphones - the best noise canceling, but definitely not the best audio
• UE (logitech) headphones
  ** the soft travel case doesn't protect them very much
  ** (un)folding them after a few months put some wear on them, but overall they're pretty decent build quality
• LG bluetooth headphones
  ** actually not bad at all even though they have an in-ear design
  ** surprisingly good quality audio: I wasn't expecting much but they really turned out to deliver
• ability to cancel noise

• need good solutions for keyboard shortcuts
• need a way to version control the configuration (xbindkeys configuration format is ideal)
