I have occasional insomnia, and while this might be a placebo effect, extensive usage of bluetooth seems to consistently make it worse.

So if this happens, it might be finally the time I ditch the iPhone brand.

There’ve also been anecdotal reports of bluetooth worsening migraines in people prone to them.

Kenya is a relatively bad example. While a lot of people are underbanked mobile banking and - payments took off in a spectacular way.[1]

It's probably easier to transfer funds via M-Pesa then from a bank account in Delaware to a bank account in Detroit

And, at least in theory, America is a wealthy country without any borders.

You’re right. I find it stupendously easy to move money within/into Kenya.

I can easily pay a street seller from my US bank account, directly to his/her phone, in seconds.

Pains me to say this because I had this international bank/credit card to M-Pesa transfers idea a decade ago, a professor dissuaded me from pursuing it.

5 years later, a bunch of services launched and many are thriving.

> This is in a long tradition of English neglect, ultimately traceable to Heaviside's status as a commoner

This is unfair on the English. Glancing at their wikipedia entries, Heavyside doesn't seem any more common than [Dirac][1] or [Faraday][2]. If I had to guess at a sociological reason why Heavyside got ignored, it's that he got caught in the transition when people started learning engineering through universities rather than apprenticeships.

[1]: https://en.wikipedia.org/wiki/Paul_Dirac#Early_years [2]: https://en.wikipedia.org/wiki/Michael_Faraday#Early_life

Heavyside's uncle Charles Wheatstone was a tradie who never went to unversity, but got knighted for services to electrical engineering. Faraday was another tradie who joined the Royal Society eight years before he got an (honorary) university degree. But in a later age Dirac became a world famous scientist, but would probably have gone nowhere if he hadn't got a scholarship to study electrical engineering at a university.

We can't wag our finger at Victorian English society for a the sin of credentialism when our own society does it much more vigorously. It's especially for our own profession, as programming is much more a craft than a thing you can learn at university.

Immigration and gay marriage and women’s rights etc. are scapegoats. The real problems are international competition (unskilled workers in developed countries have to compete with unskilled workers in Thailand and Bangladesh and Indonesia), automation (the US has higher industrial production than ever before, but it takes much less labor), changing tax laws and easier travel/communication/money movement (letting rich people live far away from production and markets, and siphon their wealth into tax havens), break-down of civic institutions (labor unions, churches, public services, local newspapers, etc.).

Your points mirror my experience, but could you explain why breakdown of civic institutions (an observation I've also made) matters?
eng101 commented on How Do Maize Moisture Meters Work?    · Posted by u/DavidWanjiru
DavidWanjiru · 11 years ago
I meant what is it do they actually measure? Turns out it's capacitance of the sample, with some compensation for temperature being made, so presumably they also have a thermometric function in-built. The devices my potential clients currently use cost about US$ 1,000, and are only typically found at grain collection centres (we're dealing with small-scale farmers). So I guess the challenge is not so much to build a smartphone app, or to even get the moisture readings into a phone, but to build a cheap moisture measuring device.

David, could you please ping me at ernest.g.n (google's mail service)
