Outlook 2016’s New POP3 Bug Deletes Your Emails!

Yikes, looks like the new version of Outlook 20016 has broken the POP3 implementation. If you are currently using the “leave on server and  delete after x days” function, the you should check your account because it seems like that the new Outlook is actually deleting your emails almost immediately after retrieving them over POP3. You might also be seeing dupes.

TL;DR If you are using the Outlook 2016 to download from a POP3 server, you should disable automatic updates and/or downgrade to a previous version or else your emails are likely to be deleted almost immediately.

“Prove me Wrong” Kickstarter Campaign

I just submitted a new campaign to Kickstarter where I ask backers to prove me wrong. The larger story is that I think the new Orison Power System Kickstarter is destined to crash and burn like way too many others have. My campaign is an experiment to see if anything can be done before everyone looses. My past efforts to intervene in crash and burn crowdfunded tech have been painfully ineffective, so I will keep trying new stuff until I get it right!

Boiling Batteries – The Effects of Extreme Temperatures on LiPo Voltage

There is a very slight and recoverable output voltage drop when charged LiPo cells are subjected to temperatures above about 75C.

Cells that have been subjected to under-voltage, however, show a very quick and non-recoverable drop to 0 volts when they reach about 75C.

If you are one of the (very few) people who are interested in all the details, read on!…

Getting Real – Using Blind Send SPI to Turbocharge the Adafruit DotStar Libraryspi,

Last time, we experimented with spiritual blind-sending as a way to theoretically speed up SPI on AVR. While there were lots of fancy oscilloscope traces and impressive demo code, there is nothing like an actual, real, practical application to get people excited. Read on to see how much faster we can make the already highly optimized AdaFruit DotStar library with a little blind-sending action… (spoiler alert – the answer is lots more faster!)

SPI with a Blindfold On- speed up by letting go and trusting the machine

Constantly checking to see if the coast is clear feels responsible, but it wastes cycles. Sometimes it is better to leap (or load) without looking. With a little hand-coded assembly, we can run our AVR processor lock-step with the SPI hardware and blindly dump new bytes into it at precisely the right moment. Because we don’t spend any time reading and testing status bits, we can increase the maximum throughput by more than 20%. If the prospect of screamingly fast yet perfectly safe SPI turns you on, read on…
