And Ma Bell has been doing it for a century. Cable rack in the central offices gets crowded after just a few decades, otherwise.
There's precedent, there are specialized tools and procedures for error reduction, and worldwide there are at least dozens, perhaps hundreds, of people with lots of experience in this very specific field.
You can feel the weight balance to tell how much of the tape is on one reel versus the other. You can rewind and fastforward by gut-feeling, with no display. Every operation of the player is tactile, and there are no hidden options menus, touchscreens, or any of that crap.
Police are not thinking on all cylinders. Anonymity works both ways. They need some undercover agents on Tor joining (and reporting on) plans ASAP (at least to the extent they are leaked to new recruits). I suspect, however, that ISIS recruits have to meet physically with handlers at some point - and at that point the undercover work becomes exceedingly dangerous.
Our small software company had a customer that would often complain, "The computer is sticking it's tongue out at me again!" For a custom module, I installed an error dialog for one particular error that displayed an animated face sticking it's tongue out. When she finally ran into this error, she was so tongue tied, she for the first time did *not* say "The computer is sticking it's tongue out at me!"
Been done on a PC/XT too: http://www.oldskool.org/pc/808...
One year vaper, previously 20 year smoker. I've had the medical labs done to show how much damage was undone in just one year.
At 41, I can run farther and faster, keep up with young folk better than most of my non-smoker friends of the same age. 3 years ago this was not the case.
It's a long-view look at where we need to go and what we need to get there. In the 1980s, commercial spaceflight was envisioned somewhat differently than it's happened, and robotics have gotten way more capable, so the refresh is definitely needed.

Excellent! Very glad to hear it. There are a
* CTFTime : http://ctftime.org/ : Website that tracks team scores, upcoming events, and writeups for previous events.
* CapTF : http://captf.com/ : My CTF dump-site that includes a calendar, links to "practice" sites (aka Wargames), and many years worth of CTF events archived
* Field Guide : http://trailofbits.github.io/c... : Specifically covering the skills / approaches, the field guide is a good read for anyone getting into this world.
* Guide for Running a CTF : https://github.com/pwning/docs... : Written by PPP (CMU's ever-dominant CTF team) along with feedback from the broader CTF community, this guide is more relevant when making a CTF, but can aid in understanding how the good CTFs are designed.
* PicoCTF : https://picoctf.com/ : PicoCTF is designed for high school students, but had an awesome difficulty curve, getting up to some relatively advanced challenges by the end of it. It's also extremely well designed, runs for a longer period of time and is a
* CSAW : https://ctf.isis.poly.edu/ : One of the best events targeted specifically at College students, unfortunately the qualifier round just finished, and the participants already selected for the final round, but you can always check out the archives of previous challenges to get a feel for the difficulty. Note that the qualifier event is typically intended to be much easier than the in-person finals to better encourage new students to get into the sport.
* IRC : irc.freenode.net#pwning : There's a lively and active community in #pwning on freenode that would be happy to help you with questions/advice related to CTFs.
* YouTube : There's a couple of different presentations/talks on CTFs over the years. If your'e interested in learning more about attack-defense CTFs and in-particular DEF CON CTF, I gave an old talk that's mostly still relevant (https://www.youtube.com/watch?v=okPWY0FeUoU), though I'd recommend you not focus on A/D at first, but just get into the regular challenge based or jeopardy boards as they're sometimes called.
The best way to prepare for CTF is by... playing CTFs. There's no real magic formula, just go out there and start working on challenges. Old CTFs are great as learning exercises since you can usually cheat and read a writeup, but avoid the temptation as much as possible. If stuck, go off and try another problem first, and only if you're

That was my answer.
