Putting On A Happy Face

There are many things I love about our Longwood students: They’re friendly, kind, thoughtful, hard-working, unpretentious. Many of them also are really good sports, as the story I’m about to tell you will show.

Recently, 8-year-old Regan Vogel, the daughter of Longwood photographer Courtney Vogel, was on campus. She’d accompanied her mom to an assignment and kept herself busy collecting colorful leaves.

All was not exactly well, though. Regan noticed the smiles of students she encountered were hidden by their dutifully worn masks. Couldn’t they do something about that? Regan mused.

In a moment of collective creativity, the group drew smiles on the leaves and the students placed them in front of their masks for a photo op.




 

Regan was happy, and we hope these photos make you feel that way, too.

Day 19 — Crypto Research #1

Hey, all! Welcome to CryptoCL.

I spoke with Dr. Marmorstein very briefly last Friday about the research I had done on clblake. I’m going to add my notes onto the previous blogpost. Again, they’re just notes that try and make sense of what is going on under the hood of the program.

More importantly, I started to do some research in an attempt to develop our own Cryptographic hashing algorithm. As a short and sweet refresher on Cryptographic algorithms, I found a website called Crypto-IT that discusses how certain algorithms work. I determined that the best kind of algorithm to use would probably be some form of Block Cipher. This is so that we can easily split up the given message into blocks, and perform the encryption or decryption with every block. This would definitely not be a secure algorithm, most likely, as we would probably have to use one constant key for each block. However, as far as speed is concerned, it should definitely speed up the algorithm by removing the tedium of processing each block once at a time.

There is still more studying to be done! I plan to look more in-depth into the AES and DES algorithms, as they are block algorithms and were (and still are) widely used.

See you next time!

Kyle Jenkins.

Doing the Right Thing: Students commit to wearing face coverings on campus—even outside

Humans are great at a lot of things, but one thing we find challenging is making a significant lifestyle change over the long haul.

We gain back that 10 or 20 pounds we fought so hard to lose. We pledge to be tidier, but we only do it for a while. We’re all in for recycling, but it’s time-consuming and we don’t keep it up.

That’s the reason I am so impressed that—more than halfway through the on-campus portion of this semester—most students are still conscientiously wearing face coverings on campus, even outside.

At one student event I attended, where every student was wearing a face covering, one young woman told me that a culture of mask wearing has developed on campus. She added that students who don’t cover their faces quickly find out from their fellow Lancers that it’s not acceptable behavior.

Please encourage your student to continue to follow the guidelines for wearing a face covering, observing social distancing and washing their hands. Their vigilance is key to remaining on campus until Thanksgiving—but, more importantly, to staying healthy.

Also, even though the weather is cooling a bit, we’re continuing to encourage students to spend time outdoors by creating spaces conducive to socializing (with appropriate distancing, of course). This includes 100 Adirondack chairs and four fire pits spread throughout campus.

One hundred Adirondack chairs have been spread throughout campus to encourage students to socialize outdoors.

Four fire pits have been installed on campus: one between Moss and Johns halls, two near Upchurch University Center and one on the Stubbs lawn.

The chairs and the fire pits seem to be a hit. Here’s part of a thank-you note one student sent to a staff member about the new amenities:

“I just wanted to say thank you so much for transforming the outdoor space into an easily accessible and welcoming atmosphere to get students outside. I really have thoroughly enjoyed sitting in the Adirondack chairs or picnic tables on Stubbs and look forward to testing out the new fire pits!”

Event leaves students with stars in their eyes

The clouds moving across the sky at times decreased visibility but they did nothing to dampen the enthusiasm of the Longwood students who turned out recently for an evening of stargazing.

“Even with the clouds rolling in, we were still able to view the moon, Mars, Saturn and its rings, as well as Jupiter and its four inner moons: Io, Europa, Ganymede and Callisto,” said physics major Austin Hedges ’21, president of the Society of Physics Students (SPS), which co-sponsored the event with the Outdoor Club.

Giving participants that close-up view of “outer space” was an 8-inch telescope equipped with a GPS system programmed with the locations of thousands of celestial objects.

Leah Eick ’23, a nursing major and Outdoor Club media and equipment chair, got an eyeful thanks to the sophisticated equipment. “I’m fascinated by the planets. Just being able to look at something so far away and see the beauty of it is amazing,” she said.

Dr. Kenneth Pestka II, a physics professor and the SPS faculty advisor, said students received training and practiced using the telescope before taking it to the event. “Once the operator has correctly aligned the telescope, it can accurately track objects, and it can also find celestial objects for the user,” he said.

The Society of Physics Students and the Outdoor Club are just two of Longwood’s more than 175 student organizations. With adaptations for Covid-19 guidelines in place, these organizations are providing students with opportunities to get together to do things they love and make new friends.

Outdoor Club president Crystal Rosenbaum ’21, a nursing major, said her group has been “jam-packed with activities” this fall, including weekly bike rides, outdoor yoga classes and a sunset hike on the High Bridge Trail attended by 25 students.

The stargazing event is another facet of the club’s mission to “get students interested in the outdoors and to continue that interest past their college years,” she said.

The event put Ashley Roberts ’21, a sociology major and Outdoor Club member, in mind of camping trips with her dad where they would lie on their backs and look up at the stars.

“It’s something that’s always interested me,” she said.

Daniel Alvarez ’23, an English education major and treasurer of the Outdoor Club, is a nature lover who spends a lot of time at his home in rural Northern Virginia “down at the creek fishing” and exploring the woods with his dog. He had a telescope when he was a kid, but it was nothing like the one the physics students set up for the stargazing activity.

“It’s nice to be able to look through a telescope that lets you see so much detail,” he said.

Austin Hedges ’21, president of the Society of Physics Students, sets up the telescope for the evening’s stargazing. The telescope has a GPS system that is programmed with the locations of thousands of celestial objects.

That’s just the reaction Hedges was hoping for.

“I think the participants really enjoyed being able to get great views of these objects,” he said. “Especially with Mars, Saturn and Jupiter because with the naked eye they are just small dots in the sky. With the telescope, we could clearly see the red color of Mars, the beautiful rings of Saturn and the bands across Jupiter’s atmosphere.”

The event was such a hit that the two clubs are planning to do it again in the near future—hopefully when the weather will be more cooperative.

“Outer space is so vastly unknown to society as a whole,” said Rianne Woudsma ’23, a physics major and vice president of the Society of Physics Students. “I’m hoping we can get more people interested in what’s out there with these events.”

Day 18 — clblake Research

Hey all! Welcome to CryptoCL.

A bit of a short day today, as far as this research project, at least. I spent about an hour to 90 minutes researching clblake. I went through the program and looked at how wfr was able to accomplish parallelism with BLAKE256. A lot of the code is setting up things for the program to utilize and calculate into the hashing function. A lot of blake256 functions were also translated into the blake256.cl file, to be used by the kernel. There is a lot of moving parts when it comes to this blake256 implementation.

Tomorrow, I will discuss with Dr. Marmorstein about the notes I took, and figure out where to go from there.

Thank you!

Kyle Jenkins.

Day 17 — Tutorials, Again #6

Hey all! Welcome to CryptoCL.

As we’re nearing the final days of working on the Hands-On OpenCL tutorial, I am wrapping up Exercise #09. On Thursday, I was able to resolve the issues I was facing with getWorkGroupSize and getInfo. Both problems were resolved by declaring and assigning a cl::Device, instead of using the DEVICE defined variable.

The program began to seg fault after these issues were resolved and I was able to program the code. The cause of the seg faults appeared to be some issues of some un=assigned values, values that were not assigned correct values, and filling a vector that would hold the partial sums of the program was being assigned the incorrect amount of items. After fixing these assignments and removing the for loop to fill the vector, the program runs to completion, but does not return the right value.

I met with Dr. Marmorstein to discuss the solution and, after digging through the code, we discovered that a value “nwork_groups” was not being initialized before the partial sum vector was being created, so the vector was being initialized as a vector of a null size. Switching around the order of code allows for the program to run and print the correct value of pi.

Lastly, during this same meeting, my next plan of action was made clear — I am to study a project found on GitHub called clblake. It is an implementation of an older version of BLAKE using OpenCL. Having a look at how GitHub user wfr handled implementing the cryptographic algorithm can offer insight on how we can implement our own implementation.

Until next time!

2016 Vice Presidential Debate put Longwood in the international spotlight

Just about four years ago, Longwood was in the international spotlight as the host of the U.S. Vice Presidential Debate.

Hosting the debate was an unparalleled experience for the entire Longwood community—especially students, who signed up in droves to volunteer for the event, putting them at the epicenter of an experience they’ll never forget.

We thought today would be a good time to look back on that experience and everything it meant for Longwood, including:
—Increased awareness of our university with more than 40 million viewers and the equivalent of more than $80 million in media exposure
—C
areer boosts for students who made important connections with those organizing and covering the debate
—Opportunities in Longwood classrooms to put an academic focus on the meaning of citizenship and democracy

I hope you’ll enjoy the videos below, which will give you a glimpse into the impact this momentous occasion had on our campus and our community.
