Not a bother to you maybe...

In my work I find GSM carrier NAT infrastructure to be very annoying. Firmware running on the phone must be aware of a "use it or lose it" mentality in the carrier, in my experience this is usually around 15 minutes for TCP, then the NAT hardware flushes your route and it effectively disappears (breaking the protocol). UDP is even shorter.

In systems which must be bi-directional, this issue of keeping the connection alive is a concern, not so much for the phone but for the server which may be sending data back to the phone sporadically. It also forces the phone firmware to perform the initial connect, so useful server-based utilities are hard to put on the phone without modifying them.

IPv6 would (likely) provide a static IP address on the phone resolving all of these issues and providing better support for downstream communications from a base to the phone(s).

Startup Out of MIT Promises Digital Afterlife — Just Hand Over Your Data 241

Posted by timothy
from the ashes-to-ashes-dust-to-nsa dept.
v3rgEz writes "A new startup out of MIT offers early adopters a chance at the afterlife, of sorts: It promises to build an AI representation of the dearly departed based on chat logs, email, Facebook, and other digital exhaust generated over the years. "Eterni.me generates a virtual YOU, an avatar that emulates your personality and can interact with, and offer information and advice to your family and friends after you pass away," the team promises. But can a chat bot plus big data really produce anything beyond a creepy, awkward facsimile?"

I still have my original Blue and Yellow RadioShack Notebooks that I purchased when I was 12. As a practicing professional Engineer now I want to say thanks for that leg up.

For all the kiddies reading this, realize that back in the 80's there were no readily available resource other than small electronic stores and mail order catalogs for young people to feed their interest in electronics. The material that Forrest Mims wrote was an invaluable resource into learning how design digital circuits using the new IC technology for that time.

I never made that flanger/phaser (audio effect) circuit though...

It is true that some newer Radio modems (eg. Telit models and now some new models from Cinterion) have the ability to run scripted programs on the baseband processor. I played with a Telit modem that could run Python scripts. I really don't think that the commercial modems that normal smartphones use would have that capability though.. it would be a dumb thing for the modem manufacture to add in.

Likely the smartphone modem will also have a GSM chipset (eg. Qualcomm) as well; this is mainly separate from the baseband processor and have limited contact with it (eg. maybe need some AT commands to control the GSM modes).

In general, the firmware running on a baseband processor is very hard to change. Changes to that processor must be re-vetted through several approval processes (PTCRB and usually one or more carrier, eg. AT&T) and consume time and money. It is for this reason that you cannot program your own code into this processor (I'm guessing scripts don't count as a program as they are sandboxed within an internal VM-like system).

it leaves us with a question: is this film for people who have read the book, or for people who haven't?

The movie could care less who is watching it. I would say that, for 99% of these type of films, it is never a good idea to watch it if you have any sort of fondness over the book on which it is based. A single 1.5 - 2 Hr movie simply cannot put enough content onto the screen to match that of a decent sized book, and so the book fan will be unsatisfied. All that is premised, of course, on the movie plot not being a hack job of the original book.
