For some reason, S/Mime encryption is sometimes finnicky. The other day, I was helping my friend try to debug his problem on why his s/mime on internet explorer was not working when he was using the outlook online application. I decided to publish what we found to work for us here so that others may not have to struggle to find the answer.

First, the issue we encountered was on Internet Explorer on Windows 10 when using Outlook WebApp (OWA). After going to settings > mail > s/mime, he had the ability to sign and encrypt emails, but could no…

When using the Jetson Tx2, I found that building OpenCV from source has been beneficial. This allows for other configurations for OpenCV that the Jetson JetPack does not support. For the most part, I followed the tutorial linked here.

The first step is to remove any instances of OpenCV that may already been previously installed on the Jetson. You can do this by applying this command:

It is recommended that you also purge the pre-downloaded (from JetPack) numpy and re-install it using pip:

Hopefully, this guide will clear up any installation problems for you or just make it easy to install JetPack 4.2 onto your Nvidia Jetson TX2.

The Setup

Here’s what you’ll need:

  • Nvidia Jetson TX2 developer kit
  • two ethernet cables
  • a host PC
  • a keyboard and mouse (you’ll need one for the Jetson to set it up and one for your host PC)
  • A USB Hub for your Jetson (to plug in the keyboard and mouse)
  • Potentially a network switch

I did not end up using a network switch but this could be necessary if you do not have enough Ethernet ports available.

This is where I plugged in my two Ethernet cables and I was able to flash Jetpack 4.2 no problem!

Currently, I am four weeks into an REU (Research Experience for Undergraduates) program that lasts ten weeks. I am participating in an REU that is for computer science majors or anyone who has a strong interest in computer science. When I was applying for this, I had absolutely no idea what I was getting myself into.

Applying for an REU

I lucked out. My university sent me an email saying that an REU at Texas State University was accepting applications. But hey, if you are looking for different REUs, just click here. The day that the application was due, I decided to apply. I…
