Can I only transfer files to my Kindle Paperwhite using the cable that shipped with the device?

I read a lot of out of copyright (and sometimes out of print) books, which I download from and then transfer from my Mac to my Kindle, usually with the excellent Calibre app. I just connected my Kindle to my Mac with a regular micro USB cable, and while the Kindle charged okay it didn’t show up as a storage device on my Mac and Calibre didn’t recognise it, either.

I then tried another micro USB cable, and that didn’t connect the Kindle as a storage device, either (it charged it, though, just like before). Finally, I dug out the micro USB cable that shipped with my Kindle and this one worked: my Mac recognised my Kindle as a storage device, and Calibre was able to send books to my Kindle.

So, should any micro USB cable work fully with my Kindle (i.e., connects it to my Mac as a storage device, as well as charging it)? If not, what’s special about the cable that shipped with my Kindle?

Can’t transfer files to galaxy S3 from laptop?Kies not getting Installed in lap?

I am having a galaxy S3, I can’t connect it to my laptop.When I connect it with USB it’s not getting mounted and so unable to transfer any files.

In my laptop Samsung kies is not installed, hope it may be the problem but in my laptop kies is not getting installed its showing “no internet connected!!” even if am connected to WiFi. Am totally stuck and frustrated, please can anyone help.Its so painful to carry such a phone without file transfer :-(.

Mechanical equivalent of heat => transfer from work W to heat Q

Consider the following experiment to determine the mechanical equivalent of heat $mu = frac{Delta W}{Delta Q}$

Not seen in the picture is a weight with known mass hanging down the cord. When you start cranking, you compensate the weight force $F_G$ with the friction $F_F$. It’s value is the difference of $F_G$ and the force held by the dynamometer.

One can calculate the work put into the system via $Delta W = F_F cdotDelta s = (F_G – F_D) cdot 2pi rn$, with $r$ the cylinder radius and $n$ the number of revolutions. (you don’t have to consider vectors calculating $Delta W$, because $F_F$ and $s$ always point to the same direction $Rightarrow$ $phi = 0 Rightarrow cos(phi) = 1$)

By measuring the temperature, one can obtain $Delta Q = C_{total}cdotDelta T$.

To the questions. What are possible outcomes for $mu$? In an idealized case, where no energy gets lost/dissipated, one can clearly assume $mu = 1$. What’s the meaning behind $mu > 1$ and $mu < 1$?

My ideas and assertions:

  • In a closed, ideal system, one can completely transfer all mechanical energy $W$ in heat energy $Q$
  • One cannot transfer all heat $Q$ back into $W$ (Perpetuum mobile 2nd kind)

This yields, $Delta Q$ must always be greater than $Delta W$, because you can’t transfer everything into mechanical work $Rightarrow mu leq 1$. But, viewed the other way round, if $Delta W$ is less than $Delta Q$, where does the energy to raise $Q$ come from? The cylinder is in thermal equilibrium with the room temperature, before one starts to crank, so there is no input from another warmth bath.

Is it possible to transfer E-O157 from simply touching something with contaminated hands?

Today I went to eat at a local hamburger chain with my family. It was the type of restaurant where you can clearly see the workers making and prepping the food. While observing them make our food, I witnessed the cook take out the raw hamburger patties (with a gloved hand), put them on the grill, grab the buns and cut them in half, line up the plates, place the toppings on the bun, then continue cooking the hamburger, all with the same gloves. Being a little paranoid about my children getting unnecessarily sick, I immediately informed the manager and requested new buns and toppings with fresh gloves. The manager didn’t seem to think a whole lot about it, but still granted my request, but I definitely had to spend the rest of the stay with some death stares from the staff. After leaving, I started to wonder if I was being a little unreasonable since I have been seeing this practice more and more at different restaurants and fast-food joints.

I have read ALOT of questions on this site about the risks of cross contamination but most of it involves best practices and food being cooked together, like this, and this, and this.
Based on all my reading, I already know this is not good practice, but what I am curious about is if any of the bad stuff, like E-O157 can actually be transferred to the buns and toppings in this manner.

Am I overreacting about the risks associated with this practice, or are the risks relatively low? More specifically, is it even possible to transfer enough of the bad stuff to make someone sick by using the above practices?

Bash script to get the result from rsync transfer and zip it as a directory in the original directory

OK, I guess this is weird.
I have a small script very simply has a bunch of commands:

if [ "$(whoami)" == 'David' ]; then
    rsync -a --delete-excluded --exclude-from=.rsyncrc $(pwd) ~/Sites/local-testing-0/modules/
    rsync -a --delete-excluded --exclude-from=.rsyncrc $(pwd) ~/Sites/local-testing-1/modules/
    rsync -a --delete-excluded --exclude-from=.rsyncrc $(pwd) ~/Sites/local-testing-7/modules/
    rsync -a --delete-excluded --exclude-from=.rsyncrc $(pwd) ~/Sites/local-testing-2/modules/
    echo "Checked out for David"

And there are also other cases according to the current logged-in user. Note that the source is the current directory (see the $(pwd)). I want to add a case that takes the current directory and makes a zipped folder out it. By zipped folder I mean no tarbomb, and it must be in zip format. I’d want to take the output of the rsync transfer, because it already filters stuff. I tried using named pipes. I could also use the file .rsyncrc for exclusions in the tar/zipping process. It reads like this:

# Meta
- .rsyncrc

# Repo itself
- .git
- .gitignore

# Distribution Packages
- dist/

# Other files
- */.DS_Store

So if I could just use this file for exclusion in the zipping process, than it would be great too. I didn’t really test this, but I’m not sure it’s possible. The output should be placed in ./dist/, which is excluded from the rsync/zipping process.

Bonus points if the name of the output zip filename had a version number -suffix, taken from inside the file that has the same name of the folder with “.php” appended. The line with the version number is always like this: $this->version = '0.0.1';

Question: Can I Withdraw Money From Variable Annunity in IRA and Transfer the Cash to Another IRA w/o Tax…

If I have a variable annuity that is IRA (traditional) designated and want to “cash out” its value and place that cash into a different IRA (still traditional) at a different institution, does the cashing out invoke a tax penalty (even if I don’t keep it and put it directly into another IRA)? If it’s taxed, it is true that it’s not capital gains, but rather regular income tax for annuities? Thank you for your help. When I said “cash out,” I did NOT mean annuitize the holdings. They are not yet annuitized and are still in mutual fund and “cash” form. I basically want to take some of the cash out and put it into a different IRA, because they have cheaper fees at that place.

I need automated file transfer software for Windows

I am looking for a recommendation for software that automatically moves files from drive A to B.

When Drive A is nearly full oldest files should be moved to drive B and when Drive B is nearly full oldest files should be deleted. Moving and deletion should only be based on how full the drive is not how old or how big the files are and the software should warn and prevent the OS from restarting or shutting down (due to update or user input) while transfer is happening.

Is there any software that can handle this kind of process automatically on window. I can’t run any other OS than Windows so that is vital.
