Object detection is one important type of computer vision task: given an image, localize and identify the relevant objects in it.

Object detection algorithms can solve problems difficult for humans, like identifying vehicle models from satellite images, counting the number of people in a crowd, or rejecting unripe fruits from a conveyor belt of fresh produce. The last example is what’s known as a sporadic visual search problem, where a huge stream of repetitive data contains anomalies only infrequently and sporadically. Humans struggle with these types of problems due to cognitive fatigue. Object detection algorithms, however, excel at this.

TL;DR: sleep is important

One 10cm plate and seven screws later.

I broke my jaw at the end of August by standing up and fainting—way to go, right? I got up out of bed in the morning, felt dizzy, blacked out, and fell. I woke up within a few seconds and noticed that my jaw felt out of place. The left side felt stuck higher up, so the right side of my bite didn’t close. I also had a scrape on my chin and my ear was bleeding.

My mom rushed me to the dentist, where they did a panoramic dental x-ray to find that my jaw…


HKN, the Course 6 honor society at MIT, is often thought of as the club that hosts free food study breaks, the underground guide to Course 6 classes, and the occasional resume review event. However, there’s much more than free boba and Chipotle— one of the most important services HKN offers is the opportunity to tutor and be tutored.

HKN eligible Stef Ren ’19 reviews a student’s resume.

What is HKN Tutoring?

Tutoring is the second-largest branch of HKN after the Underground Guide, with 83 student tutors in fall 2017. Tutors for HKN submit the classes and number of hours they’re willing to tutor, and they are manually matched with tutees by the…


When I started my research project in the MIT D-Lab Mobile Technology Lab I was excited to build my first smartwatch app using the Samsung Gear S3. Despite being super excited about the project, setting up the development environment took me an entire month 😧 Here’s how to get to the Hello World stage 10x faster than I did.

The goal for this tutorial.

The Samsung Gear S3 uses an open-source operating system called Tizen that’s based on the Linux kernel. You can program apps for the watch in C (“Native”) or with HTML/CSS/JS (“Web”). …


Every spring, about 150 high school students come to MIT’s campus for Blueprint, a weekend learnathon and hackathon where students learn programming skills, then build apps that apply them in creative ways. This year, students learned iOS or web development at the learnathon and built hacks experimenting with things like game design, IoT, Chrome extensions, and computer vision.

We were really impressed by all the projects and the energy of everyone who came to Blueprint. Thank you so much to everyone who came — we hope you enjoyed it! Here’s a sampling of highlighted projects that won prizes at Blueprint.

A puzzle for hackers, snackers, and slackers.

(part 1 of [1, 2])

We return to you this year for our third round of the HackMIT admissions puzzle! The purpose of the puzzle was to identify motivated, resourceful hackers who will enjoy at HackMIT and make cool things.

After the doges and nyans of past years, we decided to theme this year’s puzzle around another internet favorite, Randall Munroe’s XKCD comics.

Before we start, thanks to all the puzzle makers — there are too many to name all, but special thanks to Stef, Anish, Kate, Andrew, Fernando, Anthony, and Jack!

Given that the HackMIT organizing team is mostly computer science majors, it’s only logical that when we encounter a problem, we look to software to solve it. And when it doesn’t exist (or doesn’t work the way we want it to), we build our own. Over the last few years we’ve built a ton of software, both for internal and external use. We’re happy to release all of our internal and external tools as open-source software, catalogued at code.hackmit.org.

code.hackmit.org contains information on all of HackMIT’s open-source software, including the help queue and judging system.

Though all hackathon organizers tend…


Thanks so much to everyone who came to Blueprint, HackMIT’s high school learnathon and hackathon! It was such a pleasure to see so many bright students working on such cool projects. The teams below were selected through our judging system as this year’s Blueprint winners. Here are their descriptions of their hacks:

Main Division

The CV Pong team.

CV-Pong is a variation on the classic game of pong. Instead of a boring 2D space, CV-Pong is played in 3D, with the player’s perspective behind their paddle. Players control their paddle using blue gloves and their laptop’s webcam (the CV in CV-Pong stands for computer vision). …


Congratulations to all of the teams that competed in this year’s HackMIT! Teams had 24 hours to use their ingenuity and technical skills to build and test their hack, then present it. The teams below were selected by judges through our voting algorithm as this year’s winners.

1. Air Guitar

G. Beams, K. Leidal, M. McEachern, N. Matthews

Air Guitar uses Apple Watch and iPhone to reimagine the air guitar concept. Apple Watch’s accelerometer along with iPhone’s multitouch interactivity provide the perfect mechanism to create air guitar music by tracking strum and finger patterns. The simple, elegant iOS application is the result of…
