Woodchuck-Related User Behavior and Network Environment Study

Hello world!

We at the Hopkins Storage Systems Lab (HSSL) are trying to understand
how you, the tech elite, access and use data and how you access the
Internet on mobile devices.  We are interested in you, because we
think that your data-use habits may be indicative of what might become
common in a few years time.

We want to understand how you access and use data on mobile devices to
improve the user experience on mobile devices.  Specifically, we want
to:

  - Improve disconnected operation;
  - Make accessing data faster;
  - Increase battery life;
  - Reduce network connectivity costs; and,
  - Simplify data management.

We suspect that significant amounts of data that you use are
downloaded on demand and that this data could be effectively
prefetched.  Although prefetching sounds easy enough, there are a
number of issues that need to be considered: when should data be
prefetched? what data should be prefetched? how do we avoid exhausting
free space? how do we enable applications to coordinate the use of
shared resources?

To this end, we are conducting a user study.  We'd like you to
participate by running our data collection software, which gathers
information about the data you use, your network connectivity, and
your battery use.

Hi!
Will the results of the study be made publicly available and freely
(re-)usable?

Cheers

Hi, Nils,

Thanks for your question!

There are two types of results: the data collected and anything built
using the data.

The TLDR version:

The raw data will not be published, but the software developed
(Woodchuck) is available under the GPL and already works fairly well.

More information, as well as the software, is available at:

  http://hssl.cs.jhu.edu/~neal/woodchuck

The longer version:

The data collected will be published in aggregate form only.  That
means: neither raw data nor identifiable results will be published.
This is necessary to protect the privacy of anyone who chooses to
participate in the study.

The reason I'm collecting the data is because I want to understand how
to schedule delay-tolerant transfers, things like downloading

MeBook error: libQtWebkit.so.4 file

I can not open my MeBook epub reader now.
I run it in terminal. then get error:

MoWebMail works no more :(

I use MoWebMail to check my google emails but now is more than 2 weeks
that the system works no more.
If i open MoWebMail this open MicroB on the web page
http://mail.google.com/mail/mu/?login ..... [some parameters to obtain
the authorization token]

This web page works no more, so i can't use MoWebMail.

Some suggestions?

My guesses: filesystem corruption (overclocked much?), or out of free 
space.

The first is easiest and quickiest fixed by a full reflash, though only do 
that if you have backups first.
