ServiceNow Automation Using Chrome Extension

I am releasing my Google Chrome extension with tools to automate many ServiceNow ticket tasks.  It is a easily extendable extension in which you can autopopulate and autoroute tickets, automatically refresh your queues, play a sound when a new chat comes in, present hints and tips to agents, and many other features.

Every ServiceNow implementation is different so don’t expect to be able to drop this extension right in. To use it will require modifications specific to your implementation of ServiceNow.  If you understand basic Javascript you should be able to make use of this.  No APIs are used other than what is available in ServiceNow itself.

This tool was developed using the Chrome Developer Tools (Ctrl+Shift+I) to get fields and ids you will need to make the tool work. I do not recommend even attempting to use this unless you are a fairly experienced web developer.

All code is available at my GitHub link at the very top of this web site or click here

UDOO X86 Microboard Breakdown

Front of the board

The UDOO X86 is a single board computer that runs an Intel 64-bit chipset. It also has a separate chipset with a full implementation of Arduino. It runs Windows 10 and any flavor of Linux. The board is touted as as the “new PC that can run everything.” That is quite a bold claim!

In this breakdown we will examine the Udoo X86 and see how it stacks up against other SBCs!

Old Skool NES Classic Case Fan Mod

Pi Classic Fan Case Open

This is a followup to my awesome Old Skool NES Classic RetroPie build.  When I posted my build on Reddit several users that already had the case noted that the case tends to get very hot.

That’s not good, but since the case is so awesome I was determined to find a solution.  This mod requires no soldering, no drilling, and is dead simple and cheap.  It also does not modify the look of your NES Classic RetroPie setup at all!

Raspberry Pi 3 NES Classic RetroPie Build

Our PI Classic case has an opening lid!

I confess I have never been a big fan of emulation.  It never felt like playing the real thing to me.  However this setup really looks, feels and plays like the genuine article.  We will use a nice case, premium controllers and a Raspberry Pi board with RetroPie to create a truly authentic retro gaming experience.  If you haven’t heard about RetroPie yet it is a Raspberry Pi distribution that supports emulation on dozens of systems such as the NES, SNES, N64, Sega Genesis, and a whole bunch of other awesome retro systems.  An entire system can be built for less than 100 dollars.  If you missed out on the $50 NES Classic release before it was shortly discontinued (I did) then here is a really cool build that will let you build your own version that has many advantages such as being able to play NES / SNES / GameBoy / Sega / N64 / many others.  It’s also about half the size of the NES Classic.  Here’s a comparison of a NES Classic (the new tiny one, not an original NES) vs our build:

NES Classic vs RPI 3 Build

Check If Raspberry Pi is Undervolted Or Throttled

I uploaded a quick gist that will measure your Raspberry Pi’s true clock speeds using the vcgencmd. Don’t believe what other tools like cpufreq tell you that your Raspberry Pi is running at because they are lying to you! The true clock speeds are controlled by the firmware and vcgencmd is the official way to interact with the Raspberry Pi’s firmware and hardware and are the only readings you can really trust!

amiibo NFC Backup Guide for Mobility and Safety

N2 Elite Manager with N2 elite chip loaded

My girlfriend and I are huge fans of the Nintendo Switch and especially The Legend of Zelda: Breath of the Wild. The Switch is praised for its portability but whenever she comes over she brings the Switch but carrying all the accessory was a big pain.

There are over a dozen amiibo figurines that work with Breath of the Wild and can give you very powerful items and abilities. But bring her whole collection of amiibo figures on top of the switch itself became too big of a load. To solve this she found a very compact and protective carrying case that made it very easy to take the Switch around safely.

Kali Linux 2017.1 + Raspberry Pi 3 + RPI 7″ Touchscreen = Plug and Play!

Kali actually running and connected to local WiFi using built in WiFi

The Kali Linux penetration testing distribution has been available for Raspberry Pi for quite some time. However, it can be quite a chore to set it up, especially with a touchscreen.

Recently I purchased the official Raspberry Pi 7″ touchscreen and was astonished when I put the SD card in and Kali booted up right to the desktop ready for me to log in!

Overclocking Samsung Pro Plus MicroSD to 99MHz on Raspberry Pi

In my quest for maximum performing MicroSD cards in the Raspberry Pi I decided to purchase the top performing card in most benchmarks which is the Samsung Pro+. However, the common overclock for the Raspberry PI SD port to 100MHz does not seem to work with these cards and they become unstable. However, through a little bit of tweaking and experimentation, I found that these cards can be clocked to 99MHz and work just fine and provide a substantial performance boost. Read on for the details!
