Simple solution for you: buy a metronome, fasten step-tracker to it, then turn on metronome.
Occasionally stop the metronome to read the step-count, adjust the speed & time to hit your step-target.
Repeat daily or weekly to hit your target, then share the data with your plan.
Meanwhile you can watch TV, read a book, relax in a hot-tub, etc.

If a metronome won't swing with tracker attached, perhaps a paint-shaker?
Or build something with motorized Lego or Erector set.

Submission + - Internet of Things endangered by inaccurate network time, says NIST (

An anonymous reader writes: Current standards of network timekeeping are inadequate to some of the critical systems that are being envisaged for the Internet of Things, according to a report [] by the National Institute of Standards and Technology (NIST). The report says 'A new economy built on the massive growth of endpoints on the internet will require precise and verifiable timing in ways that current systems do not support. Applications, computers, and communications systems have been developed with modules and layers that optimize data processing but degrade accurate timing,'. NIST's Chad Boutin likens current network accuracy to an attempt to synchronise watches via the postal system, and suggests that remote medicine and self-driving cars will need far higher standards in order not to put lives at risk because, for instance, a self-driving car fails to distinguish between a plastic bag blowing in the wind and an obstructing pedestrian. He notes [] "modern computer programs only have probabilities on execution times, rather than the strong certainties that safety-critical systems require,"

KAMRYNabf writes: The 2014 chemistry Nobel Prize recognized important microscopy research that enabled greatly improved spatial resolution. This innovation, resulting in nanometer resolution, was made possible by making the source (the emitter) of the illumination quite small and by moving it quite close to the object being imaged.

Submission + - Leaked Document Reveals Upcoming Biometric Experiments at US Customs (

sarahnaomi writes: The facial recognition pilot program launched last week by US Customs and Border Protection, which civil liberties advocates say could lead to new potentially privacy-invading programs, is just the first of three biometric experiments that the feds are getting ready to launch.

The three experiments involve new controversial technologies like iris and face scanner kiosks, which CBP plans to deploy at the Mexican border, and facial recognition software, according to a leaked document obtained by Motherboard.

All three pilots are part of a broader Customs and Border Protection (CBP) program to modernize screenings at American entry and exit ports, including at the highly politicized Mexican border, with the aid of new biometric technologies. The program is known as Apex Air Entry and Exit Re-Engineering (AEER) Project, according to the leaked slides.

These pilot programs have the goal of “identifying and implementing” biometric technologies that can be used at American borders to improve the immigration system as well as US national security, according to the slides.

Read this.

The comments on that page already seem to do an excellent job of refuting it.
The author's first 3 points are quibbles of what to call the "riddle" or who wrote it, not addressing the content.

A great creation, made using a great new technology, obviously thought of by a bright mind, and it's graduated in... wait for it... inches.


I guess that's what sets the US and Burma apart: one of the two countries can make antiquated objects with 21st century technology. (No wait! Even Burma is switching to the metric system!)

Inches / metric is not an issue. Give this a moment's thought.
Just apply a scaling-factor to the design & print it, you'll have a metric version.

His dial-caliper design already has comments at thingiverse giving the size to print at to produce a metric version marked in mm.

Good for you! ...but was it overgrown with forest & forgotten?

If so, what a relevant comment, and I'd love to hear about your being raised by European squirrels while foraging for berries..
If not, kind of pointless, as this was about a area where civilization was overgrown, not an old town with people still living in it, with operational roads.

It is public knowledge the corporate security contractors had full access to the information being gathered under the NSA auspices. Private for profit individuals with total and full access to all the intelligence information

I'm going to need a cite for that because I've been following this pretty closely and this is the first I've heard of private citizens having "total and full access" to the NSA's data.

Wasn't Snowden a corporate security contractor?

I highly doubt those shotguns have 14 inch barrels.

Why would you doubt that?
It's a direct quote from the GSA request for bids.

And the minimum barrel length mostly just applies to normal folk. Law enforcement can get stuff that's restricted for most folk, or at least, we need to get the right special permits for. If it requires custom work, what do they care? It's government money.
(may not be custom, I don't know if there are standard 14" law-enforcement barrels, there may be)

I'm sure an 18.5" barrel just would not be tacti-cool enough for our IRS lads, what with rescuing hostages, taking down cartels, you know, all that IRS action-hero stuff they do.

All power corrupts, but we need electricity.
