Coding for a cause

first_img Wyss Institute creation is designed to instruct anyone from a 5-year-old to an intermediate programmer Harvard students teach computer science in local middle schools Planting the seeds of STEM Root, the code-teaching robotcenter_img When he was just 4 years old, Jelani Nelson got his first taste of what computers could do, and it came in the form of an animated plumber named Mario.For his birthday that year, Nelson’s parents gave him a Nintendo Entertainment System, and he quickly immersed himself in the world of video games. By the time he was 10, Nelson had moved on to PC and online gaming, and it was there that he discovered — nearly by accident — the code that makes the online world work.“I got into computers through gaming, and I had a computer at home with an internet connection,” he said. “I remember at some point I right-clicked on a webpage on my browser, and saw that it said ‘view source.’ That was how I learned HTML was a thing.”That discovery, Nelson said, not only set him on the road to teaching himself to code — first in HTML and later in other, more complex languages — but in some ways also put him on the path that eventually led to Harvard.These days, Nelson is the John L. Loeb Associate Professor of Engineering and Applied Sciences at the Harvard John A. Paulson School of Engineering and Applied Sciences, where his work is focused on developing new algorithms to make computer systems work more efficiently. At the end of this academic year, he will leave Harvard to join the faculty of the University of California, Berkeley.“I’m in the theory of computation group here, and broadly what that means is modeling computation mathematically and proving theorems related to those models,” Nelson said. “So we may want to prove that a particular problem cannot be solved, or that any method that solves a problem has to use at least this much time or memory. Proving that there are methods that are memory- or time-efficient — that’s generally called algorithms.”Streaming and SketchingGenerally speaking, Nelson’s work is focused on two types of algorithms — streaming and sketching, which are focused on using very little memory.A basic way to understand streaming algorithms, Nelson said, is to imagine someone reading a list of numbers, then asking for their sum.“If I ask you at the end to tell me the sum of all the numbers, you can do that by keeping a running sum in your head, but you don’t need to remember every number,” he said. “But then if I ask you to tell me the fifth number, you won’t remember it, because you only kept this running tally. You only used just enough memory to answer a specific type of query.“That’s a simple example, but there are other situations that are not so simple, where it turns out there are very memory-efficient algorithms that don’t need to remember every item, but can answer nontrivial queries about the past,” he added. “For example, if I’m Amazon and I want to know what were the popular items people bought yesterday between 7 and 8 p.m., I want to be able to answer that without my data structure actually remembering the record of every sale during that time.”,By comparison, Nelson said, sketching algorithms are designed to let users answer questions about compressed data even if they don’t have access to the original data.“In the literature, a synonym for a sketch is a synopsis,” he said. “So sometimes you might have multiple sources of data … and you want to be able to make a sketch of one, and a sketch of the other, and then use those sketches to compare them without having access to the original data.”For a real-world application of such algorithms, Nelson said, consider your spam filter.“So the idea is that an email is a document, and you can apply a sketching algorithm to it to create a lower-dimensional representation,” he said. “You can then run a machine-learning algorithm on that data. And the idea is that now it is more efficient because it’s working on lower-dimensional data.”From the Caribbean to Cambridge While it wasn’t long after first discovering HTML that Nelson set out to teach himself to code, he quickly ran into an obstacle: The only bookstore in his hometown on St. Thomas in the U.S. Virgin Islands was woefully lacking in coding manuals.“When I was in seventh or eighth grade, we visited the mainland, and I went to a bookstore and bought an HTML book,” he said. “For practice, I wanted to make a website for my little sister. We both liked the [Nickelodeon show] ‘Rugrats,’ and I wanted to put a picture of Tommy on her webpage … but I was afraid of violating copyright, so I called Nickelodeon and asked them permission to include images from ‘Rugrats’ on the site, and they refused. But they took my info, and shortly afterward, we got a box in the mail with a bunch of swag, like VHS tapes and T-shirts and toys.”At the same time, Nelson said, he had also become deeply interested in math, and began taking part in competitions for middle schoolers run by the Alexandria, Va.–based nonprofit Mathcounts. As a seventh-grader he was one of a handful of students who represented the U.S. Virgin Islands at a national competition held in Washington, D.C.As a senior in high school, Nelson began to delve deeper into programming. He bought several books on the computer languages C and C++, and applied to MIT after seeing it was rated as the best in the nation for both computer science and mathematics.“When I got to MIT, I think I was surprised by all the things I didn’t know,” Nelson said. “In my high school, we didn’t have AP classes. … The highest level of math you could take was single-variable calculus, so I just didn’t know what existed in math beyond calculus. I had never really seen creative mathematical problem-solving before, so it was a big wake-up call.”It was at MIT, first as an undergraduate and later as a grad student, that Nelson began to show off one of his more unusual skills — his blazing fast typing speed. In 2010, he scored the top spot on TyperA, a website that hosts online typing tests, with a staggering 170 words per minute.“I used it as a procrastination mechanism,” he said. “I would just go and do these typing speed contests, and at some point I got to be at the top of the leaderboard. More recently people have passed me, but I think I’m still in the top five.”,Coding for a cause Nelson’s educational efforts aren’t limited to the Harvard campus. Shortly after completing his doctorate at MIT in 2011, he founded AddisCoder, an educational program in Ethiopia, where his mother is from, dedicated to teaching coding and algorithms to high school students in Addis Ababa.“I had graduated in early June, but my postdoc in Berkeley didn’t start until August, so I decided to visit some relatives in Ethiopia,” he said. “And I thought, ‘If I’m going to spend a lengthy amount of time here, what am I going to do besides hang out?’ And I thought, ‘Why don’t I teach a course?’ I ended up with 82 students, and I was the sole lecturer, with one volunteer teaching assistant.”Working with the Meles Zenawi Foundation, created in honor of the former Ethiopian prime minister, the program taught 175 students in the summer of 2018, coming from public schools across the country. Nearly half of them were female.“The classes run for four weeks, and each day there is about 90 minutes of lecture, and the rest of the time they’re in the computer lab, solving problems, so it’s very hands-on,” Nelson said. “When I partnered with the Meles Zenawi Foundation in 2016, we had a meeting with the Ministry of Education, and we said, ‘We see no reason why this shouldn’t be balanced; we’re certain you can find very capable women to recruit into the course.’ And they listened. The last two offerings have both included over 40 percent girls. Also, almost all students in the course had never coded before and really didn’t know what computer science was, so the program really helped to evangelize computer science to kids who otherwise might have never been exposed.”In addition to the classroom time, the program this past summer held a career day, which drew more than a dozen people — including two from Kenya and several from Ethiopia — who work in fields that require knowledge of computer science.“We wanted them to see that not only are there Facebooks and Googles, but that there are job opportunities locally for them as well,” Nelson said.

A Strategy to Help Military Caregivers Use Resources/Supports

first_imgWritten By: Mary Brintnall-Peterson, Ph.D., MBP Consulting, LLC, Professor Emeritus, University of Wisconsin – ExtensionAs a professional, you spend time searching for resources, supports and services to assist military caregivers with hopes what you discover will be helpful to them. You are ecstatic when a caregiver uses a suggested resource and comment on how helpful it was to them. So why is it that some caregivers use suggested resources while other don’t?Hidden Heroes, American’s Military Caregivers, a study funded by the Rand Corporation explores military caregivers use of resources/supports. They found that only 15-30% percent of post 9/11 caregivers used recommended services in the past year. Religious supports were used most often while stipend type programs were used least (Ramchand, et al., 2014). Why were these resources used and not others?The easy answer is, caregivers only use resources/supports they value because they understand how it will address their particular concern or issue. A strategy I use to help the caregiver understand the benefits of possible resources/supports involves several steps. It ends with the caregiver developing a goal detailing how they will use a particular resource/support. The steps include:Step #1: Listening carefully to what the caregiver is sharing and together identify his/her major caregiver concern. This involves a “give and take” process of listening, sharing back what you heard, and having the caregiver agree or disagree with what you are telling them you heard. Probing can help get to the core issue and concern. This step is time consuming but essential if you are going to get to the military caregiver’s core issue or concern. Before moving to step 2 the caregiver must have a clear picture of what the concern or issue is.Step #2: Identifying and sharing possible resource and support options. Explain each resource in detail pointing out how they could benefit the caregiver. Have the military caregiver identify the pros and cons of each resource/support from their perspective.Step #3: Asking the caregiver to select one resource/support option they are willing to try. By the caregiver selecting the resource/support they acknowledge how it can address their concern and benefit them.Step #4: Assisting the caregiver in creating a goal. The following questions can be helpful in developing the goal which should be written out.What resource/support will be used?When will it be used?How often will it be used?For how long will it be used or done?Where will the caregiver go to get the resource/support?Goal example: I will call the doctor to make an appointment for a physical exam on Friday before noon. Another example: I will mediate for 10 minutes on the deck after lunch on Monday and Friday. It is essential that the goal is achievable so the caregiver is successful so they will try other resources/supports. One of the benefits of exploring lots of resource/support options is that if the first one selected didn’t work out, there are others to try. Sometimes it may take the caregiver several tries before finding a resource/support that works for them.Step #5: Last step– Determining how you will support the caregiver so they are successful in reaching their goal. This could include calling or sending an email asking about the progress on their goal, making a contact for them so its easier to access a resource, making a referral, etc. Make sure the caregiver leaves with the goal in writing including details on how you will support them. Encourage the caregiver to post the goal in a place they will see it often. By writing the goal and having it visible the caregiver has a higher chance of success.This strategy is designed to enable the caregiver to see the positive benefits or value of using a specific resource/support to assist them with their caregiver role and responsibilities. With the caregiver identifying their concern or issue, exploring possible resource/support options, selecting a resource/support and developing a specific goal the caregiver will be more successful in addressing their concern or issue.ResourceRamchand, R., Tanielian, T., Fisher, M., Vughan, C., Trail, T., Epley, C.

7 Creative Things to Do With Gaff Tape

first_imgGaff tape can be used for so much more than fixing cables to the ground. Here are some other ways you can use this sticky filmmaking staple.Gaffer’s tape, gaff tape, camera tape, spike tape. Whatever you call it, don’t call it duct tape. Gaff tape is the most common tool you will see on set.The tape is made with a heavy cotton cloth, rather than vinyl or plastic. The adhesive used in gaff tape is more heat resistant, making it popular among lighting technicians. Unlike duct tape, gaff tape wont leave a residue when it’s removed.1. Make a space bra.Image from starwars.comWhen George Lucas was filming the original Star Wars, he told actress Carrie Fisher that “there’s no underwear in space.” That meant Princess Leia couldn’t wear anything more than her hair buns and white robe. To keep the film PG, Fisher had to wear makeshift pasties made out of gaff tape.2. Save your footage from being formatted.Did you just pull a full memory card out of the camera? Put a strip of red gaff tape on it to prevent it from going back into the camera. Keep that card taped until you dump the footage. If you put the card inside a case, tape the case shut. This is an easy way to help you keep track of your cards.3. Salvage your shoes.Did you get a hole in your sole? Maybe your shoes are squeaking too much. Put some gaff tape over the bottom of your shoes to help quiet them.Did you wear white shoes when you are only allowed to wear black ones? Start taping your whole shoe. Gaff tape won’t leave any residue, so your shoes will still be white when you take the tape off.4. DIY tracking points.Will you be using motion tracking when you edit? Make some cross hairs with two pieces of gaff tape. You can even put gaff tape on light stand, like in this VFX breakdown from Jean-Baptiste Lefournier for the Beat Assailant music video RUN.You can see more breakdowns like this over at RocketStock.com.5. Cover your built in laptop camera.Maybe you don’t trust your computer after you accidentally streamed your whole face to a hotel conference while trying to fix an issue at an event. A little gaff tape won’t hurt the screen. You’re on your own when it comes to the microphone.6. Mark your gear.Keeping track of your own gear and rentals can be a hassle. Gaff tape comes in multiple colors. Color code your cameras and gear to make sure everything goes back to its rightful owner.7. Gaff tape on the go.Image from StrobistNow that you know some cool tricks for using gaff tape, make sure you always have some on you. You might not have room for an entire roll, but you can easily have some in your pocket.Have an old gift card or hotel room key? Wrap a foot or two of gaff tape around it. One of the coolest tricks can be found in this tutorial from Strobist. Learn how to make a gaffer’s tape key fob. All you need is a paper clip and pencil to carry 40 inches of gaff tape with you everywhere.Need more cheap gear to help stay organized on set? Then check out these articles from PremiumBeat7 Tricks for Keeping Your Camera Equipment Organized12 Essential Filmmaking Tools Under $204 Cheap Practical Lights That Can Work Wonders On SetKnow of any other tape tips that we missed?
