Make an Offline Mirror of a Site Using `wget`

Every time I want to mirror a website using wget I go to Google and read the same two pages on the subject.  One at Fosswire and the other at Guy Rutenberg’s Blog.  I thought I’d mirror the content here so that I can find it more easily going forward – maybe you can benefit from it as well.

It’s worth noting that httrack is a much more elegant solution and it also has a command line option for mirroring – but wget is more widely available.

Kindle Unlimited – Not That Great

Kindle Unlimited

Amazon recently announced their Kindle Unlimited service offering access to 600,000 book titles and 8,000 audiobook titles for $10 a month.

Access to all of those books sounds great, but the book selection itself is somewhat lacking. The Kindle Unlimited library includes many popular titles but new releases published by the ‘big five’ publishing companies (Penguin Random House, Simon & Schuster, HarperCollins, Macmillan, and Hachette) are not included because Amazon doesn’t have agreements with them.  (See their blog post about the Hachette/Amazon Business Interruption)

If you want to read a lot of books, but don’t care which books you read then maybe Kindle unlimited makes sense.

goTenna Creates a Cell Network Out of Thin Air

Gotenna

Gotenna

Brooklyn-based startup goTenna offers a solution for off-the-grid travelers who need low-cost connectivity for their smartphone – and it doesn’t rely on satellites.

goTenna is a small, rugged device designed to make “No Service” no problem. Just pair your smartphone with a goTenna and communicate off-grid with those near you who also have goTenna, anywhere on the planet, regardless of access to cell reception or wi-fi.  goTenna allows you to send and receive texts and share GPS locations on beautiful offline maps, without ever relying on central connectivity.  Depend on it in all kinds of situations: when hiking in remote areas, traveling, attending music or sporting events or during an emergency. Plus, because goTenna is end-to-end encrypted, it’s not just for when you’re off-grid, but when you want to be.

Simply connect the goTenna to any iOS or Android device via Bluetooth.  After that, all you have to do is download the goTenna app and fire off a message to anyone else who might be in range.  Depending on your elevation and environment, the signal can travel upwards of 50 miles.  By default, only your intended recipient will be able to read your message, but a “shout” feature allows messaging any goTenna user within range.  goTenna does not use cell towers or WiFi so it will work even if all other forms of communication are unavailable.

The goTenna offers end-to-end encryption using RSA-1024 public-private key ciphering and because there is no central server there is no proverbial “back-door.”  Also, you can opt to have your messages self-destruct after your intended recipient(s) read them.  If it’s on 24/7, it will last 30 hours or so. If off, it will hold its charge for about a year and a half.

The goTenna is being offered for pre-order at a cost of $149 per pair.  Following the first batch of sales up to $50,000, GoTenna plans to raise the price to $299 per pair.  There are no fees or charges associated with using goTenna once you own the devices.  goTenna plans to fulfill their first batch of orders by late fall 2014.
