Walking and rubbing your eyes don’t mix. (We cracked up so much after this)
It’s been great knowing you Posterous :(
I’m sad to see this awesome blogging site going away. Recently they were purchased by Twitter and now they can no longer focus on maintaining their service.
Posterous was my main blogging tool of choice because of how easy it and flexible it was with its email posting. So sadly, I’m in the process of migrating my content from posterous to tumblr (i didn’t want to set up a whole wordpress blog since i mainly do small posts anyway).
Hopefully i don’t mess up my tumblr account while i do some importing.
Reader kylewpppd asks:Have you seen the post of a man in Siberia throwing boiling water off of his balcony? Can you provide a better explanation of what’s going on?
As you can see in the video (and in many similar examples on YouTube), tossing near boiling water into extremely cold air results in an instant snowstorm. Several effects are going on here. The first thing to understand is how heat is transferred between objects or fluids of differing temperatures. The rate at which heat is transferred depends on the temperature difference between the air and the water; the larger that temperature difference is the faster heat is transferred. However, as that temperature difference decreases, so does the rate of heat transfer. So even though hot water will initially lose heat very quickly to its surroundings, water that is initially cold will still reach equilibrium with the cold air faster. Therefore, all things being equal, hot water does not freeze faster than cold water, as one might suspect from the video.
The key to the hot water’s fast-freeze here is not just the large temperature difference, though. It’s the fact that the water is being tossed. When the water leaves the pot, it tends to break up into droplets, which quickly increases the surface area exposed to the cold air, and the rate of heat transfer depends on surface area as well! A smaller droplet will also freeze much more quickly than a larger droplet.
What would happen if room temperature water were used instead of boiling water? In all likelihood, a big cold bunch of water would hit the ground. Why? It turns out that both the viscosity and the surface tension of water decrease with increasing temperature. This means that a pot of hot water will tend to break into smaller droplets when tossed than the cold water would. Smaller droplets means less mass to freeze per droplet and a larger surface area (adding up all the surface area of all the droplets) exposed. Hence, faster freezing!
Reset Whispersync- Furthest Page Read
Here’s the issue -
When using Whispersync, staying on the correct page across multiple devices works great–until you decide to re-read your content.
You read thru a book on either your Kindle and your iPhone (or another Kindle). First time thru, you stay in sync on any device. Later you decide to either re-read or restart the book. Unfortunately, the ‘Sync to Furthest Page Read’ will always be the furthest page you got to, so your furthest read page remains at either the end of the book or the furthest page you got to and Whispersync will be let you know when you open that book on the device. You can tell it not to go to the furthest page and continue reading. Go to the other device and try to sync, and you will be taken to the furthest page read, not the place you were at when you stopped reading on the other device.
This is a problem in a couple of ways. The simplest is that it makes it hard to re-read or restart any book and use Whispersync to keep your place on more than one device.
Solution – Reset the Furthest Page Read
Use the same device for all of the steps below before opening the book on a different one, the below example is using a single Kindle
1. Set the Synchronization off on your Amazon Account (Go to Amazon -> Your Account -> Manage Your Kindle -> Manage Kindle Device Synchronization -> click the “Turn the Synchronization off” button to turn off the synchronization)
2. Wait about a minute, then exit & re-enter your book
3. Go to the beginning of your book on the Kindle
4. Sync to the furthest page. If it tells you that you’re on the furthest location, you’re good to go.
1. If not, select Cancel on the sync message, exit and re-enter the book to attempt the reset again. (I think that the Amazon databases have to get reset-thus the delay; in any case, it always works for me on the 2nd attempt)
5. Turn on the synchronization setting on your Account – your Furthest Page read will be reset to your new location.
6. On your other devices–if further along in the book, you will have to go to the beginning of the book, but once done the Furthest Page Read location will sync with your Kindle.
Like I said, its not the most elegant solution, but it works.
I’m glad that I found this solution that works, and simple enough. I had to wait a bit more than a minute (perhaps 5) after i turned off Syncing, but eventually it worked.
