The article below is more like a memo to me about how to fast setup DevStack based private cloud on Ubuntu 16.04. It might take several hours or days solving all kind of issue related to different part of OpenStack and system configuration if start process without good stack knowledge. Or detailed step-by-step notes from previous successful installation. I hope it will save some hours for me next time.

Install Ubuntu 16.04

Create bootable USB drive from ubuntu iso

wget http://ubuntu.volia.net/ubuntu-releases/xenial/ubuntu-16.04.3-server-amd64.iso
dd if=ubuntu-16.04.3-server-amd64.iso of=/dev/sdb

Latest iOS update brings among other traffic data in Kyiv. In addition, map is less outdated compare to how it is usual in Apple maps. Now map based on OpenStreetMaps. Routing is far from perfect. Traffic is also not always relevant. But at least map improves.

Good news is that map edits that I did during last year using OSM editor now are in new Apple map. Therefore, the way to fix Apple map mistakes exist.

Some streets names are not translated properly.

It looks like I have found last available on iOS navigation software from Ukrainian developers. It is NavLux from Luxena. When it works it looks like:

But it is sometimes hard to make it work. My application purchase expirience:

Not possible to try it before buy on iOS. Must pay 15$ first.
Purchase Server Unavailable. Cannot activate the map.
Support not answer on both in-app and site forms requests.

Application start work in about 3 days after purchase (I suppose Luxena have fixed the issue with its server).

air quality

AirVisual node

Yet another air quality monitor. Measure PM2.5 and CO2. Have a rechargeable battery that allows hours of work without a power plug. Have Wi-Fi and mobile application to access data.

What is wrong with this device – no support for Ukraine. No external Air quality data for Ukraine, cannot choose Ukraine from a country list during setup. It is also ambient light sensor missing (only manual screen brightness setup).

UPD from 2018-02: Now support Ukraine, but only two private external monitors available (in Kyiv and Brovary)
