Last week, I made a post about my project for command-line encryption and decrpytion of Outlook emails using a smart card. A day before I worked on that project, I was actually working on another, tangentially related project relating to encryption and openssl.
At my current workplace, emails are frequently frequently encrypted/decrypted in Microsoft Outlook, using a smart card that is issued to every employee. At work, we primarily use Windows, and either the default Microsoft authentication tools or middleware such as ActivClient are used in order to interface with our smart cards / smart card readers. Until I started this project yesterday, I had only ever used GUI applications in order to do anything related to my smartcard.
OpenCV (open computer vision) is a c++ project devoted to computer vision applications. For this weekend project, I was specifically looking into how it could be used in an Android application. To start off, I read through the OpenCV android tutorials located here and here. Unfortunately, these tutorials referenced an older version of Android Studio… (nowadays, there’s a fancy new Android studio that even has a dark mode!)… so I had to try my best to translate outdated instructions towards the new stuff.
Doing more work with Ubuntu on windows. I accidentally overwrote my Ubuntu on Windows installation, deleting all of my Linux files! Oh well. Since I’m starting from scratch, I am working on getting things back to working again, starting with Jekyll and GitHub/Gitlab.
Wow, haven’t updated blog in like two years. Right now I am trying to install gedit on the “Ubuntu on Windows” feature of Windows 10. I was able to get it installed with “sudo apt-get install gedit,” but it still wasn’t working correctly… something about a gconf file not working. I wasn’t able to change any of my preferences! After googling the problem for about two hours, I think my issue is that I haven’t installed gnome yet! I guess that’s a required thing, considering that gedit is a gnome application.
I’m trying to make jekyll on github pages work nicely with my website host, and it’s rather confusing. I thought I had it all figured out yesterday, but I decided to do something else so I’ve been working on that for the past few hours. I want the jekyll site to appear at www.xoid.us, but I want all my old stuff to appear somewhere, like old.xoid.us. But in the process of doing that, I suddenly was unable to access my cpanel, or any non-jekyll part of my site! Pinging it did not work! But wait! If I check the status of the website on sites like site24x7.com, it shows that it works. I just tried opening the site on my phone’s 4G internet connection, and it works. So I think that the hosting company may have blocked my IP address for some reason… So anyways, I finished up the DNS editing on my phone, and now I think everything works as I expected!
All right, so I made my website. Took me forever to figure out how to do all sorts of things… First, I learned how to use git. Then, I learned how to install jekyll and get it to display a website on localhost. After that, I had to figure out how to redirect the github URL to xoid.us, and that was the worst part, because I never knew what my A and CNAME changes did, because of caching and stuff! Well anyways, it turned out it worked. Up until this point I had been doing everything in linux! I had originally started in windows, with the Github GUI and Powershell, but I was so confused and lost that I just started from scratch by learning from the git reference website online. The tutorial had linux commands in their examples so I used the linux partition on my laptop. That turned out pretty well.
So anyways, after I was getting nowhere with the CNAME record stuff, I rebooted and switched back to windows, and checked xoid.us in the browser…. and it worked!! After that, I made a short CV draft page and started adding a blog thing. I have noticed that the powershell and the github GUI is a lot easier to use now that I kind of understand what git is.
For most of the beginning of my trip, I was asleep. I had to wake up early to catch the bus to Indianapolis, and I ended up falling asleep while waiting for the bus. Luckily, I woke up in time to catch the bus, and as soon as I sat down, I passed out for the 45-minute drive, and someone had to wake me up to get me off the shuttle at the airport. Once I got into my gate, I went to sleep again, because I had around a 3 hour wait. My first flight to Chicago got delayed, which made me worry that I would miss the second flight. When I got to ORD, I got to take the shuttle bus for delayed passengers directly to my terminal, which was nice. I didn’t miss my second flight, and in fact, that flight got really delayed due to catering issues.
Thought of some more things to talk about
This year has been very busy, due to having to do a senior design project.
There are a few non-computer related things that I have been doing while at my internship.
Last week Saturday, our AFROTC detachment had the Operation 218 event that I was in charge of. It went pretty well (I don’t have any pictures of it). In the morning, the younger cadets were in a simulated in-garrison ‘boot camp’ environment, and for part of it they had to make beds and fold clothes. We needed beds for the cadets to use, so I had to bring mine over in the morning, from my room to the training place, which was around half a mile away.
Today’s the last day of Spring Break before school starts again. I have PT tomorrow at 6AM, so I have to sleep early tonight.
Here’s a quick list of what happened after the rafting trip: Went home Came back to school Went to California Came back to school Went home again Came back to school Went to field training Went home again Came back to school Went to Washington Came back to school Went home again Came back to school
In the beginning of this year, I decided to join more clubs, and the club I ended up joining was the outdoor adventure club, which is basically a club that likes to go camping or something every once in a while. Two weeks ago, we went white-water rafting, which was really fun. Most of the trip was subsidized by club money, too. The place we went to was in West Virginia, and it took about 12 hours to get there by car. We spent two nights at a camping area near the river and then went rafting on Sunday morning. On saturday, there was this thing called bridge day, which was this thing where people jumped off this really tall bridge with parachutes and float down into the river. That was fun to watch.
Sorry I haven’t written for a while
A few weeks ago, I had this AFROTC thing called LDW, which is a one-night campout that is supposed to simulate a deployed environment. It was very strict and structured– everything we did was tightly scheduled, and we had to always have a “wingman” (buddy system) with us at all times. It was fun, though; we got to go rock climbing and play paintball, and I learned a lot about Air Force procedure.
Right now it’s 4:38 in the morning; I woke up so early because there’s something wrong with my iPod alarm. I have to leave for PT at 5:30 (Mondays, Thursdays, and Fridays), but I don’t want to go back to sleep, because this Monday I did, and I ended up sleeping through the PT session.
So far I’ve only had two days of class, since school started on a Thursday.
