Freeing a 5th gen Fire tablet from its master.

I have sort of a history of bending android devices to my will.  It's sort of what I do, and while I'm not going to claim credit for the work done in this post, I will say that that experience fueled it.  So as you read through this, bear in mind that I'm experienced, and have a pretty good idea of what to do to get myself out of trouble when android mods go sideways.  Yes, I've bricked a few devices, rendering them useless, but that's been few and far between.

Paypal scam.

I've been meaning to write about this for some time now.  Back in October of 2016, I found myself in posession of a Samsung S7 Edge that I really didn't like, and a brand new shiney Google Pixel, that I did indeed like.  So I did the logical thing, right before Christmas, I tried to sell it.  At first I tried cragistlist, as I've found it more effective than Ebay for some other things I've sold.  Nothing, not a single bite.  So I fell back to Ebay, as I really wanted to get this thing sold.  A day or so after I listed the item, I was contacted through ebay's messaging system, by a potential

How to break 40 years of resiliency.

So back in the late 60's, "The Internet" was in its infancy, several groups of technologists at various institutions were running a network called ARPANET.  ARPANET eventually evolved into what we call the internet today.  Systems connected to ARPANET, and todays Internet are each assigned an IP address, which is how other systems on the network communicate with it.  Your computer has one, your phone has one, your fridge might have one, the web server I run that you're reading this blog on has one.  Some have several.  The problem with IP

Lets Encrypt, Nginx proxy, CentOS 7

I've been interested in the Lets Encrypt project since I first heard about it, quite some time ago. It's a cool idea, automatic free certificates for everyone!  I've been using startcom for the majority of my personal sites, minus swbcrawler, which I purchased a cheap commercial cert for.  A few months back, Lets Encrypt finally opened up for publi use, and I giave it a little poke.  I didn't end up putting any of its certs live at the time though.

Hack My Derby

In 2011, Dave Kennedy and his crew started a little conference, called DerbyCon.  Named for its location, in Louisville, KY, it's an awesome infosec con, with a great atmosphere.  Because of the name, derby hats have been a staple. Much of the staff wear them, and many attendees also wear them.  Many of them are modified, lights, displays, whatever.  This eventually lead to a contest, in 2014 attendees were able to enter their modified derbies in the "Hack Your Derby" contest.

NFC Ring

Yesterday, I received my long-awaited NFC ring in the mail.  And it is awesome.  Well, as awesome as you can expect it to be anyway.  I had backed them on kickstarter about a year ago, and now that they've worked through their issues, rings are coming to those who backed.  Its neat technology, and it's got some interesting uses.  At the moment all I'm using it for is unlocking my phone. 

Awesome times.

So, years ago, I was working Technical Support for an ISP. This was late 90's, early 2000's. I was just out of business school, with a fresh Associates degree in PC Networking under my belt. At the time, computing was at what I perceived as sort of a standstill. Yea, things were progressing, but it was all just redoing the same thing better. Memory was getting cheaper every year, CPU's were getting faster, storage more affordable, OS's were being udated to newer better features, but it was all just the same muck. My 486 was replaced with a Pentium 3.

Puppet 2.6, filebucket permissions.

Just a little snippet. I'm working with puppet, and foreman. Im working through the Pro Puppet book from APress. In the first section, they have me create a sudo module, which will pull /etc/sudoers from a puppet file bucket, and put it in place on the agent. I was running into the following error.

NEED HELP FINDING A LOST HIKER - California, Sierra Nevada Mountains.

The brother of a high-school friend of my wife's, is missing. He was on a camping/hiking trip in the Sierra Nevada Mountains, in the Mammoth Lake area. He was separated from his friends when his car broke down, and never met back up with them as planned. The hunch is that he went on a hike on his own while waiting for his car repair.

He's been missing for almost a month. It doesn't look good.
