meichenf | 4 years ago | on: Ask HN: Have you created programs for only your personal use?

I have an ESP8266 running a tiny webstack on my local wifi that is wired to a low voltage relay that turns on my hot water heater (tankless). Combined this with a Apple shortcut so I can tell Siri to turn on the device (send a post request to the unit). Basically just a hacked together system to avoid using Homekit. It's been running great for 6 years with no maintenance so no complaints.

Schwab also does not charge fees for new treasury bond issues. I assume this is a loss leader for them and they make back their money in the secondary market.

1) Setup and test your VPN before you go. If you decide to use an IPSec VPN expect it to fail around-half the time (even if properly configured). YMMV

3) Microsoft Translator works well in China and has 2-way text to speech, offline language packs (Traditional and Simplified), and photo analysis / text overlay.

5) Taking a bismuth tablet with every meal to avoid getting sick. Enjoy the street food.

So maybe something like Irish-American Heritage Month (March), Polish American Heritage Month (October), or Jewish American Heritage Month (May)?

There is a lot of information available on this subject. So I’ll start with a link to the FHA’s Traffic Control Systems Handbook - http://www.ops.fhwa.dot.gov/publications/fhwahop06006/chapte...

The basic idea regarding vehicle and pedestrian movements is that the system can be entirely pretimed (interval control) or divided up into phases (phase control). The typical idea of operation is that any compatible phases should be able to run concurrently so long as there is time available. During Pedestrian Walk and Clearance time however these phases cannot be forced off or timed out. (Otherwise people could get hit by cars) This limits the amount of time the button can be pressed during a green light and still change the pedestrian signal.
