This approach will work great on some commercial buildings and some apartment buildings but it might not work for detached homes.

When dealing 1970s (and newer) wood-frame homes
1)There is usually a lot insulation in the attics of wood-frame homes so hot air in the attic doesn't heat the home much and cold air in attic doesn't cool the home.
2)Most Wood-frame homes have vents in the top of the attic and the bottom of the attic allowing hot air to flow out the top and cool air to flow in the lower vents.

For many concrete homes: The reduced heat absorption during the day will increase night-time heating costs.

For data centers: Most of the heat comes from servers running in the data center.

The paint is awesome, it will likely help with climate change but I don't think it will eliminate the need for AC.

I wonder why telegram isn't willing to add a location rounding function. They could start with rounding to the nearest mile and randomizing the last few digits of the GPS location. Then reuse the exact same randomized locations everytime any user (with location sharing enabled) is near a previously used random location. Then add 2,3, and 5 mile rounding to protect users who live in rural locations (eg.10,000 acre farms)

There is a huge community of information security professionals, hackers, privacy nerds and defcon attendees on twitter.

If you do quick searches for #infosec and #cybersecurity you will find everything from certification advice, to conference presentations, and leading edge security research.

The connector is an M12 Industrial Ethernet Connector - as seen at http://www.designworldonline.c... The story description should be updated so that more readers find out that they can connect to their Tesla's on-board computer via a easy to find cable.

Networking is your best way to reenter software engineering. Remember networking is about helping people and developing relationships. Based on your skill set you would be quite value-able to a web design company. Many web designers contract out programming to local programmers. Go to local networking events (chamber of commerce, bni, ...). Introduce yourself as a software engineer and ask each person you meet if they know a good web designer then offer to do a short contract project at a competitive price. After completing that contract you now have recent experience. When it comes to your programming experience, I recommend getting a company name (this is usually pretty cheap) and listing all your recent experience under your company. The person reading the resume won't know that the company is just you until they interview you. On the resume topic, you might want to leave off your sales experience (and maybe some of your oldest software experience) so that your engineering experience doesn't get diluted and you might want to consider leaving off the dates so that employers don't notice your hiatus and don't guess your age. P.S. I used most of these techniques to get back into software engineering after a 8 year hiatus as a Network Administrator.
