being kept at 100% is much worse than ideal

This is at the heart of my laptop battery experience. My laptop is rarely off AC power. When I had the charger set to stop charging at 100% (and to recharge when 90%), my battery life greatly improved. OId battery dropped 60% in reported capacity in less than 2 yrs; new battery is barely down 30% in the following 4 years.

I call it Chinese electron torture for your battery -- drip, drip, drip.

Since there is no single lens that can capture a 360-degree view, obviously they are using multiple cameras. When you composite the final video, the view of the arm is obviously replaced by the same area, but from a different camera.

Does it bother you also that the ends of some of the rotor blades are not attached?

a) did not disclose fully the extent of his patent dealings, referenced one more recent issue but failed to disclose the more serious prior issues

Which he was not required to, since it was more than 10 years prior, as per the (claimed) court instructions.

b) provided false, misleading evidence contrary to judges instructions to manipulate the jury

Something like this is the one that the appeal will most likely rest upon.

c) had prior conflict with subsidiary of Samsung

Which Samsung's lawyer's didn't enquire after?

A few possibilities:
1. It is possible that another app is using the PDFReader's secret key, etc. It would still have to have given permission to the app.
2. Someone else installed it on your iPad using their own App Store credentials, gave permission, then uninstalled the app.
3. Dropbox has some other API issue that allows files to be uploaded somehow...
4. Any combination of the above.

I guess you'll see if the mystery uploads cease when you revoke the Dropbox access PDFReader has.

So some iOS app is interacting with the Dropbox app in some way (either via API or just throwing files into a folder that Dropbox must have all permissions open on).

Most likely they're using Dropbox's iOS SDK. That would have required you to give permission however.

Check Dropbox's My Apps to see if any 3rd party apps have access.

Increasing Wireless Network Speed By 1000% By Replacing Packets With Algebra 357

MrSeb writes "A team of researchers from MIT, Caltech, Harvard, and other universities in Europe, have devised a way of boosting the performance of wireless networks by up to 10 times — without increasing transmission power, adding more base stations, or using more wireless spectrum. The researchers' creation, coded TCP, is a novel way of transmitting data so that lost packets don't result in higher latency or re-sent data. With coded TCP, blocks of packets are clumped together and then transformed into algebraic equations (PDF) that describe the packets. If part of the message is lost, the receiver can solve the equation to derive the missing data. The process of solving the equations is simple and linear, meaning it doesn't require much processing on behalf of the router/smartphone/laptop. In testing, the coded TCP resulted in some dramatic improvements. MIT found that campus WiFi (2% packet loss) jumped from 1Mbps to 16Mbps. On a fast-moving train (5% packet loss), the connection speed jumped from 0.5Mbps to 13.5Mbps. Moving forward, coded TCP is expected to have huge repercussions on the performance of LTE and WiFi networks — and the technology has already been commercially licensed to several hardware makers."

Easy! There are 3 major groups of investors in the Facebook IPO fiasco.

You missed a group:

4) The institutional investors that are cozy with with investment bankers and get to buy-in at the IPO price. They are the ones that really want the first-day "pop", because it means they can off-load (some) at an easy 10-20% profit. Both of those groups like this racket, because for the next IPO, the institutional investors will come back, and the investment bankers will get more IPO fees because they can ensure a sold-out IPO to the next victim/company.
