Electroneum - First Impressions

A coworker recently sent me a link to Yet Another Cryptocurrency. Like most people, I’m pretty burnt out with all these new coins and ICO’s popping up each week. In fact, I get about 5-10 ICO spam emails in my Junk mail folder. This one looked to be just a little different, though. He was excited because this one allows you to use your phone to mine. I talked to him about how it’s a neat idea, but ultimately probably won’t be profitable, especially compare to a multi-GPU setup.

Why I switched from Android to iOS

Note: This article is not just a stringent comparison of Apple vs Android, but a look at the whole picture that I took while deciding which phone to switch to. A few months ago, my beloved Verizon HTC One M8 began to lose it’s charge at an alarming rate. It would be at 40% battery by lunch time after a day of very moderate use. Luckily, I was due for an upgrade from Verizon.

Allow a Chromecast through a WatchGuard firewall

Background I recently picked up a Chromecast for my TV so I could stream Netflix easier since XBMC’s addon is terrible if you don’t want to use a keyboard. It was super easy to setup, but after it updated and connected to my WiFi I couldn’t see it from my phone. I did some digging and found that my WatchGuard 25W was the culprit. After I added an any-any rule I was able to see it, but that left it wide-open on my network.

Fix “Some settings are managed by your system administrator” in Windows 7

Background A few months back, I was doing cleanup on a system that I had cleaned of malware. Whatever junk was on there had configured a local proxy server to run, but Malwarebytes had ripped it out. The system unfortunately still thought it was supposed to use the proxy server that doesn’t exist; consequently, I had no internet access. That’s an easy enough fix, right? I open Internet Options and change the LAN settings to not use a proxy and close it.

Fix HAXM Emulation Error in Android Studio

Requirement Note: Android Studio requires an Intel processor with VT-X support for it’s built-in emulators to work. If you want to do Android development with emulators on an AMD processor, I would highly suggest using Genymotion. If you’re not sure if your Intel processor supports VT-X, Intel has an article here. This error is occurring because Android Studio requires Intel Hardware Accelerated Execution Manager (Intel HAXM) to run it’s emulators.

Fix Ruby on Rails Certificate Issue

While attempting a “rails new” command, I was greeted with this lovely message: An error occurred while installing rake (10.4.2), and Bundler cannot continue. So after doing some research, it turns out all you need to do is a Gem update: gem update --system Unless of course, this results in this error like it did for me: ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError) SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://api.

View/Reset SickRage Web Password

Background I recently forgot my password for SickRage and was surprised by the little documentation online. I have it installed in a jail in FreeNAS, so that’s what I’ll be focused on here but the instructions should be exactly the same if you have it installed inside an OS. Steps It’s actually really easy, assuming you have command-line access. In FreeNAS, open a shell on your SickRage jail and edit the following file:
