spwestwood··on Ask HN: Who is hiring? (November 2015)
OpenSignal - London, UK (Full time, permanent) At OpenSignal we're using mobile apps to tap into the smart phones we're all carrying around with us to build up global crowdsourced sensor networks. Our first sensor network is for wireless signal [1] where we are building a global database on the coverage and performance of wireless networks (both mobile + WiFi) on a scale that has never before been possible. Our second sensor network is WeatherSignal [2], which uses the barometers, thermometers and hygrometers on smart phones to crowdsource weather data and we have already published a scientific paper [3] showing the potential of this approach. Our third sensor network is WifiMapper [4] which leverages sensors and the community to build the best free Wifi database in the world.

If the concept of crowdsourced sensor networks appeals to you too then please get in touch. We are hiring for all manner of different roles right now (Android, Full-stack, Backend (Python), Frontend, UX/UI & Data Science(R, Pandas, Numpy, Spark)) but most of all we are just looking for smart, like minded people rather than people with specific, existing skills. We raised our $4 million series A [5] from Qualcomm Ventures, O'Reilly Alphatech Ventures & Passion Capital and we are growing fast.

The UK version has a much worse design:

Responses are guaranteed after 10k signatures, which is a bit more achievable than the (current) 100k in the US. If they get to 100k then they have to be debated in parliament.

Highest number of signatures is for saving badgers. Which seems very English :)

spwestwood··on The State of LTE
That's true. The fastest 3G speeds can exceed average LTE, so it's semi-defensible for carriers to brand some HSPA+ as 4G. In our tests though, the fastest speeds are always LTE. In the last week of the 50 fastest speeds tests all but 2 (#39 and #40) have been LTE. (Fastest was 69812 Mb/s - Oman Mobile!)
spwestwood··on The State of LTE
The Japan average is also bought down a lot by one network (NTT DOCOMO). As well as the usual factors age of the network could also be an issue here. Both SoftBank (16.2 Mb/s), KDDI (14.8 Mb/s) are under 1 year old, presumably under capacity waiting for people to upgrade handsets and contracts. DOCOMO (5.5 Mb/s) on the other hand launched in 2010. You see a similar effect in the US, where AT&T's network is regularly beating the older, more congested Verizon. We expect this to even out over time.

If you are reading this and haven't signed the petition yet please do so:

https://petitions.whitehouse.gov/petition/make-unlocking-cel...

At the current rate of signatures it's going to just fail to get to the 100k. It's a really great petition because it's both popular with the public, as well as being an easy thing for the administration to change. Has there ever been a Whitehouse petition that was successful? Perhaps this could be the first.
