Here are my DEF CON notes from the sessions that I attended in 2017 for DEF CON 25:
Please fell free to do what you want with these notes. I go to sessions so you don't have to.
Here some quick links to notes from previous years: 24 (2016), 23 (2015), 22 (2014), 21 (2013), 20 (2012), 19 (2011), & 18 (2010).
I plan on attending DEF CON 26. Follow along real-time on Twitter @technewsradio.

I recently picked up a Logitech Wireless Combo Mk520 With Keyboard and Mouse to use full time with my Acer Chromebook when I'm using it in desktop computer mode.
When I am in this mode I usually use the setup with a SAMSUNG T24C550 monitor as the primary monitor and the Acer's laptop monitor as my 2nd monitor off to the right-hand side.
I like this setup because it enables wireless access to both the keyboard and the mouse using one USB port. Previously I had a dedicated wireless mouse and then a bluetooth keyboard. However the bluetooth keyboard wasn't completely full-size, would periodically drop off connectivity, and was better suited to short-term typing like like periodic emails responses on my Nexus 7.
The only draw back with the Mk520 is that the Function (F) keys are not ideally setup to match the icons on them.
The keyboard uses the basic standard keyboard layout on most Chromebooks. So ESC is ESC (Escape) and:
At the very top of the keyboard is a media control area (3 keys): back, play/stop, forward. Those don't seem to work with videos. But the sound control area (3 keys): mute, decrease sound, and increase sound do work. And the WINDOWS button is a dedicated SEARCH button; the STAR button brings up the BOOKMARKS page list; and the CALCULATOR button goes into FULL SCREEN MODE.
Over all the keyboard feel when typing is very good, and I like the pressure the keys have. In addition, I like the ability to tilt up the keyboard and to have it stand-up at 90-degrees for using your desk area for writing if needed. I would recommend the keyboard if someone is looking for the same feature set.
I recently picked up via Craigslist a "new in the box" Asus C720-2802 Chromebook to use as my new primary system for TechNewsRadio.com. The main reason was that DEFCON22 is coming up soon in Las Vegas and I needed a "relatively" secure system to attend sessions and take notes for ~8 hours a day.
My previous note taking system was relatively old ThinkPad that I had 3 sets of extra batteries for. So, I dropped about 6 pounds by moving to the C720. And I don't have to configure a fresh system to take to DEFCON and then scrub after.
This version (2802) seems like the middle build release (~Feb2014) from the original that was in late 2013 and the most current $199 version that uses the Intel Celeron 2955U processor (2848). There is also a newer more expensive C720 with an Intel Core i3 processor available.
The positivies:
The negatives:
The still to be determined:
POST DEFCON REPORT: There is now an IMAP client - CloudMagic. I am pretty sure I didn't get hacked at DEFCON. I was able to take notes all day long at DEFCON without any issues. I have not found a good solution for editing audio.

Back in Podcast #325 we had a mention and a link to a personal finance tool called Wesabe. It is no longer available.
There are other options out there like Mint and PocketBook.
If you know others then please let us know!
Here are some links to stories about TrueCrypt shutting down:
TrueCrypt is a key tool in our toolkit for protecting data and we use it everyday. If it is actually going to go away then it will leave a big whole in end-user security options for data encryption.
I recently picked up from Harbor Freight Tools the following solar power kit: 45W Solar Power Kit (#68751) for just over $150 (including tax).
Over the course of the last couple of months I've been able to try out the kit on several camping trips were there was no easy electrical grid access. The camping environment was pretty sunny but not always 100% full sun. The time of year for all the trips was summer and the location was Southern California. I ended up setting up the kit on the top of our small camper.
The main reason I picked up the kit was to keep all of my tech gear charged so I could keep tabs on email, news, and any tech issue with my sites. This was usually less than 1 hour a day which worked out well for my needs, and expectations related to being on a camping trip.
The gear I was able to keep operational using the kit included: cell phone, tablet, WIFI card, and a laptop during trips lasting up to 7 days.
I was suprised during the main daylight hours that the inverter could charge directly: the cell phone, tablet, and WIFI card. To keep my laptop charged I needed to capture to an emergency car battery system, and then use 3rd party car charger/inverter to get the right power levels to keep the laptop charged. I was also able to keep charged a USB battery pack so I could run my WIFI card during non-daylight hours when needed.
One other lesson learned, was to turn off all electronics while sleeping. This helped keep all the devices more readily available the next day then keeping them in standby/sleep mode overnight.
All in all the system worked very well and I'd recommend it.
