The Anecdote is the Antidote for What Ails Modern Medical Science by John R. Adler, Jr. M.D. It’s hard to imagine anybody being more of a medical insider than Dr. John R. Adler, the founding editor of Cureus. Adler has a Harvard medical degree, served his residency at Massachusetts General hospital, and is a Stanford professor of neurosurgery, as well as founding CEO of a leading radiation oncology company, Accuray. This makes it especially heartening that Dr. Adler is now focused on opening up medical research literature to important kinds of evidence that have often been ignored: the anecdote and the case report. Quote: “The altruism that is supposed to drive the publication of scientific research has been almost entirely co-opted by the peculiar needs of academic promotion and tenure, as well as the pecuniary demands of the scholarly publishing industry; the public good of medical knowledge has been reduced to a mere after-thought by both academia and the publishing industry.” -Gary
You can train your body into thinking it’s had medicine by Jo Marchant. There is an experimental treatment where the patients always drink from a uniquely flavored beverage every time they take their medicine. After a while, the drug is taken away, but the drink is still consumed. Amazingly, the body continues to act like it received the drug. Considering that many of these drugs have terrible side effects, these findings can impact how medication is administered. -Steven
Fleming’s discovery of penicillin couldn’t get published today. That’s a huge problem by Julia Belluz. John Adler’s reflections on the value of anecdote, linked above, were inspired by this essay by Julia Belluz celebrating the creation of another new journal, called Matters, devoted to publishing reports of small scale experiments and observations. As the publishers write on their web site: “Observations, not stories, are the pillars of good science. Today’s journals however, favor story-telling over observations, and congruency over complexity. As a consequence, there is a pressure to tell only good stories. Moreover, incentives associated with publishing in high-impact journals lead to loss of scientifically and ethically sound observations that do not fit the storyline, and in some unfortunate cases also to fraudulence. The resulting non-communication of data and irreproducibility not only delays scientific progress, but also negatively affects society as a whole.” -Gary
Machine Learning for Easier Dieting by Samuel K. Moore.
“I had a half-cup of oatmeal, with two-tablesoons of maple syrup and a cup of coffee. Oh, I put a handful of blueberries in the oatmeal, and there was milk in the coffee. It was skim milk.”
It would be wonderful to log one’s food by speaking to your tracker in this natural manner. Machine learning may make it possible, but this article reviews some of the obstacles that need to be overcome when it comes to parsing speech. -Steven
A Case of Complete and Durable Molecular Remission of Chronic Lymphocytic Leukemia Following Treatment with Epigallocatechin-3-gallate, an Extract of Green Tea by Dawn Lemanne, Keith I. Block, Bruce R. Kressel, Vikas P. Sukhatme, Jeffrey D. White. This paper from Cureus about a notable clinical outcome offers an excellent example of the kind of research that might never come to light without the work of pioneering science publishers. -Gary
This Dude’s Fitness Tracker May Have Just Saved His Life by George Dvorsky. When a 42-year-old man recently went to the emergency room following a seizure, the doctors had to make a decision in how to proceed that depended on whether the man’s arrhythmia was caused by the seizure or was chronic. The answer was found in the man’s Fitbit data. -Steven
How Can I Stop Feeling Cold by Justin Timmer. A few years ago, I spent a winter wearing only a t-shirt when I went out. I was interested in how my body adapted to the cold over time. I am happy to see Justin attempt a similar thing but with more rigor. -Steven
Letter of Recommendation: Segmented Sleep by Jesse Barron. I’ve been long fascinated by the concept of segmented sleep, where people have a first and second sleep period during the night. I’ve read historical references of this phenomenon, but not many experiences from now. -Steven
Leave that Thermostat Alone! by Michael VanDaniker. Taking advantage of the ability to export his data from his electric provider, Michael compared his electricity usage against the outside temperature to get a better understanding of his electricity use (and created some nice visualizations in the process). -Steven
Resource: Home Hacking Blood Glucose by Jenny Horner. Jenny heard about a study in Israel that showed that post-meal blood sugar spikes differ highly according to the individual. For example, ice cream is fine for some, but sushi is not. Jenny decided to apply the findings to her life. She shares the method she is using to construct her own personal glycemic index. ‑Steven
Personal Information Manager by Fabian Benetou. Fabian’s site is a fascinating mind dump of many aspects of his life. Open to all, but comprehensible only to him, there is a voyeuristic pleasure in traipsing around and seeing a glimpse into someone else’s head (another fun example is Jerry Michalski’s “Brain”). In particular, I love seeing the notes that he keeps from the books he reads, which dovetails with my interest in commonplace books. ‑Steven
Arbor Ludi: “Un proyecto de visualización de datos compuesto por una serie de representaciones gráficas que reconstruyen el árbol de juego de ocho de los mejores ajedrecistas de la historia.” Each image in this beautiful and fascinating series of data visualizations represent the playing life of a chess master. Created by the design and architecture firm Ootro Estudio, the portraits are made out of data from every move from hundreds or thousands of published games (the number varies significantly between masters). The coral-like shape emerges from the fact that in chess the first moves are common and well known, while later moves inhabit a vast possibility space. For more on the technique, see this informative post on The Zugzwang Blog: Arbor Ludi: arquitectura mental de un genio del ajedrez. (In Spanish.) -Gary
All Those New Dinosaurs May Not Be New — Or Dinosaurs by Maggie Koerth-Baker. My first experience of the messiness of paleontology is when I learned that my mug with a green brontosaurus depicted an animal that never existed (though that may no longer be true). This chart shows how often a dinosaur genus is later declared to be invalid. The error rate for dinosaurs named between 1850 and 1980 is 48 percent! -Steven
Changing river path seen through satellite images by Zoltan Sylvester. Using Landsat images, this is a time lapse that shows, over a thirty year period, the oxbow section of the Ucayali river in Peru get pinched and then cut off from the main flow of the river. You can view thirty year timelapses like this for any location on earth at the Google Earth Engine. The Las Vegas one is an incredible example of urban expansion. -Steven
The Beacon Experiments: Low-Energy Bluetooth Devices in Action by Chaise Hocking. There is a lot of interest in using micro-location to support QS projects, with much excitement focused on Bluetooth beacons as a possible solution. If you’ve been curious about how well the fairly well known Estimote and Kontakt beacons work for estimating proximity, this post is for you. ‑Gary
Do-It-Yourself Medical Devices — Technology and Empowerment in American Health Care by Jeremy A. Greene. DIY healthcare technology has existed a lot longer than the devices designed to pair with your smartphone, but the “it” in DIY, as well as whom “yourself” is directed towards, has changed significantly over time. ‑Steven
Boundary Negotiating Artifacts in Personal Informatics: Patient-Provider Collaboration with Patient-Generated Data by Chia-Fang Chung et al. This sensitive research paper explores how self-collected data can be used to support collaboration between people seeking health care and their care providers. Based on surveys and interviews, Chung and her co-authors offer a detailed analytical framework for understanding common tensions and misunderstandings, and give extremely thoughtful suggestions for designers. ‑Gary
‘Superman Memory Crystal’ Could Store Data for 13.8 Billion Years by Stephanie Pappas. It’s probably foolish to get excited by a technology that may never escape the research facility, but I’m excited by the idea anyhow. The challenge of keeping data from degrading is a big one. Libraries burn down. Magnetic tapes disintegrate. Hard drives die suddenly. The idea of storing your data on a glass disc is poetically appealing, but I am surprised to learn of it’s practicality in terms of stability and capacity.‑Steven
The Most Famous Mice in the World Right Now by Steve Hamley. I’ve been following the slow transformation of nutritional science from anti-fat to anti-carb since reading Gary Taubes cover story for the New York Times: “What If It’s All Been A Big Fat Lie?” This week there was a minor chapter in which many media reports used some work by a New Zealand scientist purporting to show that high fat, low carb diets could be bad for your glycemic control after all. The above story by Steve Hamley is the best debunking. ‑Gary
Ann Douglas Details Her Hi-tech Weight Loss Journey by Lauren Pelley. Ann Douglas, an author of books on parenting and pregnancy, lost 135 pounds over two years. She didn’t have one killer device or app, but used a suite of tools that contributed in one way or another. “I had given up all hope of ever losing all this weight,” she says. “If you’re sitting there despairing, wondering how you’re ever going to do anything about your weight problem — I was there too.” ‑Steven
Using Heart Rate Variability to Analyze Stress in Conversation by Paul LaFontaine. “Vapor lock” is Paul’s term for that feeling when you are trying to retrieve something from memory in conversation, but because of the stress of the situation (especially if it is with a boss), you lock up and your recall fails. To better understand this phenomenon and learn how to prevent it, Paul measured his heart rate variability during 154 conversations with bosses and co-workers and discovered that the biggest cause of his “vapor lock” was not what he expected at all. ‑Steven
17 Years of Location Tracking by Stephen Cartwright. Steven has been tracking his latitude, longitude and elevation every hour since 1999. In this talk, Stephen shows how seventeen years of location tracking has given him a wealth of data to explore in the form of three-dimensional data visualization sculptures. He has even brought some of these to QS conferences. They are amazing to behold in person. ‑Steven
Marrying Age: This is when Americans get married by Nathan Yau. This interactive visualization looks at the average marrying age for different demographics. You can’t see the trends over time, but it is interesting, though not wholly surprising, to see smoother distributions for demographics that tend to have more stabile economic situations, like college graduates. (Though I’m not sure if that has more to do with the relative number of people in each group.) ‑Steven
Forget me nots by Lam Thuy Vo. This explores the relationship between a woman and her archive of email exchanges with exes. This visualization above is fairly standard, but the others in the piece are more like tone poems. Appropriate, considering that dives into your archive can leave you swirling in unleashed emotion (Speaking from personal experience here. You would be surprised by how much you can relive your life by looking at old bank statements). ‑Steven
Danielle by Anthony Cerniello. This is a video of a computer generated face that ages over the course of four minutes. The length is interesting in that you can tell that change is occurring, yet it is happening slow enough that it’s hard to see exactly what is changing moment to moment. ‑Steven

This Scientist Is Turning Every Element In the Periodic Table Into Music by Jennifer Ouellette. We have seen Randy Sargent analyze his heart rate variability with a spectogram, a tool normally used for visualizing sound. This project is perhaps the inverse, turning the molecular structure of elements into audible tones. Surprisingly, “sonification” is becoming a useful analytical tool in materials science. Here’s the sound of silicon. -Steven
Building a Better Tracker: Older Consumers Weigh In On Activity and Sleep Monitoring Devices. (PDF) This study by the Georgia Home Lab that explored the value of self-tracking for people over 50. The researchers enrolled 92 participants and set them up with seven different activity trackers, then followed them for a six week period. While participants tended to believe that self-tracking could be valuable, most of them did not learn much of interest, and reason is telling: the lessons provided by the trackers were too general. “Participants who did not find the devices to be useful said that they wanted more data related to their specific conditions and that they wanted notification if the data indicated something of concern. More sensors relevant to health conditions was the most common suggestion for improvement.” -Gary
If You Want Life Insurance, Think Twice Before Getting A Genetic Test by Christina Farr and Cops are asking Ancestry.com and 23andMe for their customers’ DNA by Kashmir Hill. I’m filing both of these stories under “Ways your data can be used against you.” -Steven
BMI Is A Terrible Measure Of Health: But we keep using it anyway by Katherine Hobson. It’s not news for me that BMI is a terrible metric. But if BMI is not a good proxy for health, what metric is out there that is better and as easy to measure? This article looks at mid-section measurements as a candidate. -Steven
Your Letters Helped Challenger Shuttle Engineer Shed 30 Years Of Guilt by Howard Berkes. This is a short piece, but it touches on themes of data-based arguments, courage, guilt, and self-forgiveness. -Steven
Know Thy Cycle, Know Thyself by Ilyse Magy. Using the Fertility Awareness Method and Kindara, Ilyse diagnosed a previously unnoticed vitamin deficiency that had a huge effect on her wellbeing, as well as gained other important insights into cyclical dimensions of her health and wellbeing. ”Once I started charting, I was pretty amazed by what I was learning, but also kind of mad that no one had ever told me this stuff before.” -Gary
Why I Weighed My Whiskers by John Cousins. Inspired by an anecdote about a man’s beard growth while working on a remote island, Jon explores whether there is a relationship between his mood and facial hair. Yes, you read that right. -Steven
Stoic Self-Tracking by Alberto Frigo. One of the most consistently interesting chronicles of a self-tracking life is Morris Villarroel’s shadow of the stream, where he writes on his ongoing, multi-year life-logging projects, about which he’s given several excellent conference talks. But this week Morris turned over his blog to another deeply reflective self-tracker, the artist Alberto Frigo, whose self-tracking practice includes photographing everything he picks up in his right hand. In this post, Alberto revives an old word – operosity – in describing the worthy laboriousness of self-care. -Gary
Excerpt from Alberto’s piece:
On a bus from the Venice airport to the mountains where I am now restoring an abandoned barn to deposit my life-work, I was reading Seneca. I was reading it for different reasons; in the first place, it was what an old professor of mine quoted when he decided to give up his inspiring career and retire to a small barn near the town the bus was passing. Secondly, reading Seneca was like a counter-reaction to all the Anglo-Saxon stuff one is forced to refer to in today’s humanities. Thirdly, Seneca has often been quite superficially pointed out as one of the first persons to quantify himself.
Basis Breakdown. This an interesting take on a weekly journal, combining Basis Peak stats with daily reflections. -Steven
A Day in the Life of Americans by Nathan Yau. This visualization is a timelapse showing how Americans spend their day, based on the Bureau of Labor’s American Time Use Study. It would like to see a similar visualization, but for a single person with each dot representing a different date. -Steven
Codeology. This project takes code from github and represents them with an odd combination of 3D and ASCII text to create organic seeming shapes. After looking at a couple dozen of these, I wanted to see the shapes interact with each other. Arena fight, perhaps? -Steven
The Potential for the Most Liberal Supreme Court in Decades by Alicia Parlapiano and Margo Sanger-Katz. This excellent visualization uses Martin-Quinn scores to show the ideological leanings of Supreme Court justices’ rulings by year. More importantly, by highlighting the relative liberal or conservatism of the justice who sits in the ideological median, it shows how the character of the court has shifted through the years. -Steven
DNA Got a Kid Kicked Out of School—And It’ll Happen Again by Sarah Zhang. This a potent example of the unexpected ways that genetic information can be used against someone. We’ve already seen how 23andMe data can be used for nefarious ends. In this case, it’s a child who was transferred from his school as if he has cystic fibrosis, but only has the genetic markers for the disease. A set of norms or rights around personal data (and genetic information, in particular) has barely been established, so it will be interesting to see how many similar incidents we will see. What’s tricky is that neither side is acting irrationally. At heart is this question: How do you manage risk when a person’s DNA is part of the equation? -Steven
When Wearable Makers Shut Down, Getting Your Data Isn’t Always Easy by Stephanie M. Lee. San Francisco QS Show&Tell co-organizer Greg Schwartz is quoted in this Buzzfeed story about the recent shutdown of BodyMedia servers and bricking of the devices. In January Greg posted a how-to video users who still wanted to get their data, but this only worked until the servers were taken offline on January 31, 2016 Article author Stephanie M. Lee talked a bit about the defunct QS companies Lark, and Zeo. The Zeo shutdown sparked a record thread on the QS Forum where users still trade tips to keep instances of this late, lamented sleep tracker in action. -Gary
Working memory training could help beat anxiety by Christian Jarrett. Dual n-back tests have been championed as a brain game that actually works since a 2008 study showed that the exercise improved fluid intelligence (i.e., IQ). Those results have since been in dispute, but a new study cautiously supports the idea that dual n-back, by improving working memory, may also lessen anxiety symptoms. -Steven
Graphing When Your Facebook Friends Are Awake by Alex. There are at least five reasons to love this post about building graphs of Facebook Friends’ awake/asleep time: a surprising revelation of hidden system, uh, features; a “procedural” on hacking them that is basically comprehensible even if – like me – you don’t understand all the details; a useful general lesson about public exposure of personal data from seemingly friendly and low level status tracking; a hilarious stream-of-consciousness narrative that tries, half-successfully, to answer the question “why;” and, for all of us who have ever tried to do something meaningful with our own data, the comforting admission that the real trouble started when it came time to make a graph. Really a great post that this preview doesn’t do justice, so go read it. -Gary
This Canadian Lab Spent 20 Years Ruining Lives by Tess Owen. As much as it’s claimed that there’s a fair amount of skepticism of science, especially in the United States, there is no doubt that it carries authority in legal matters. This article shows the damage that can happen when seemingly rigorous test procedures and results are accepted without scrutiny. It’s especially galling to see how sloppy commercial testing procedures can become, and how dangerous it is to assume that professional measurement is more reliable than personal measurement, human dialog, and common sense. -Steven
Give Up Your Data to Cure Disease by David B. Agus. Another article on the opportunities and pitfalls of making medical records available for health research. While this opinion piece argues for the value of the opportunities, it makes clear that we need better data security practices to ensure that health information is used for the greater good, rather than used against individual patients. However, nowhere is the point made that research subjects can play an active role in investigating disease and making new discoveries. -Steven
Three Years of Logging my Inbox by Mark Wilson. The number of emails in Mark’s inbox correlates very well with his stress level. After passively tracking his email for three years, Mark explores how his inbox count reflects his stress level and influences his sense of self. -Steven
Measuring My Indoor Environment: Indoor Quality and Water Quality by Bob Troia. The first two parts in a multi-part series, Bob shows the tools and measurements he’s using to understand the quality of his living space. -Steven
Maniac Weeks for Extreme Productivity by Bethany Soule. A “maniac week” (coined by Nick Winter) is spent doing nothing but working and sleeping while documenting your face and screen with a time-lapse video. Bethany talks about her successes, failures, and side effects of this level of extremism. -Steven
This Chart Shows Who Marries CEOs, Doctors, Chefs and Janitors by Adam Pearce and Dorothy Gambrell. With data from the U.S. Census Bureau, this interactive chart allows you to select a profession and see the five most likeliest occupations of the partner. It will also show whether if the partner is more likely a member of one sex or the other. Refreshing to see that it represents same-sex partnerships as well. -Steven
How China’s economic slowdown could weigh on the rest of the world by Carlo Zapponi, Seán Clarke, Helena Bengtsson, Troy Griggs and Phillip Inman. The interconnectedness of global economies can be difficult to wrap your head around, but this series of visualizations from the Guardian do a good job of illustrating which economies’ rely on exports to China, and how much they are exposed to a downturn in the world’s second biggest economy. -Steven
Música hecha con el corazon. A website where you tap your current heart rate and it finds a song that matches the beat. The site is in Spanish but is easy enough to figure out. Just put one finger on the artery in your neck and click in the circle in time with your pulse. -Steven
The Chart Book: An Overview of Standard Celeration Chart Conventions and Practices. Owen R. White, Malcolm D. Neely. This pdf covers how to use a Celeration chart. Used for the assessment of students by teachers, this chart template aspires to be flexible enough to chart data clearly no matter the scale. It would be interesting to see this used for personal data. Thanks to Ryan O’Donnell. -Steven
The DIY Scientist, the Olympian, and the Mutated Gene by David Epstein. There are several surprising twists in this story of a non-professional scientist named Jill Viles, who made an important discovery about her own rare genetic disorder. What inspired me mostwas Viles’ tenacious reliance on her own capacity to reason, even in the face of skepticism from professionals who had less knowledge (though more confidence) than she did. Eventually, she connects with highly technical scientists whose research direction she influences with her ideas. Epstein got a fantasic quote from one of them when he asked the scientist if this has ever happened before. “In my life, no,” he says. “People from outside coming and giving me hope? New ideas? I have no other example of this kind of thing. You know, maybe it happens once in a scientific life.” I found myself wondering if this kind of thing will be less rare in the future. -Gary
A Drug to Cure Fear by Richard A. Friedman. This article intersects two of my interests that stem from my own self-experimentation. From my stress tracking I realized that many of my reactions in my day-to-day life are influenced by traumatic memories. From my spaced repetition practice I learned how memories can change over time through retrieval and consolidation. A study done in the Netherlands suggests that a memory can be decoupled from an associated fear response by using propranolol which blocks the effects of norepinephrine, a chemical that strengthens connections in the brain. The study has yet to be replicated, but hopefully it will increase our understanding of trauma. -Steven
Internet of Things security is so bad, there’s a search engine for sleeping kids by J.M. Porup. Ever since doing a research project on data flows for our first Quantified Self symposium we’ve had what you might describe as a below average level of confidence in the security and reliability of information traveling outside the immediate context of its collection, now that APIs connect to APIs connecting to yet other APIs. Still, even I was surprised by the recklessness and potential harm described in J.M. Porup’s brief account of a search engine that displays random pictures from internet connected consumer cameras around the world. -Gary
Algae bloom toxin linked to Alzheimer’s, other diseases by Amy Kraft. One consequence of the climate change and the depletion of fish stocks in ocean’s is the increase occurrence of algae blooms. Ethnobotanists found a correlation between algal blooms and neurodegenerative diseases among remote populations in the Pacific. New research suggests that cyanobacteria, the microorganism in these blooms, has a neurotoxin that can cause neurodegenerative precursors that develop. This neurotoxin enters the human food chain as it bioaccumulates in fish and shellfish. -Steven
Glass Half Full Succeeds in Unwinding Upsets by Paul LaFontaine. Most people have moments of irritation or worry throughout the day. Paul wanted to find out what worked better as a response to these moments. Option A was to step back and observe his emotions in a manner similar to that taught by some schools of meditation. Option B was to figure out the source of irritation or concern and think of a positive angle to the situation. What is great about this post is the very simple but illuminating experiment that he devised to explore this question. -Steven
Finding My Optimum Reading Speed by Kyrill Potapov
As an English teacher Kyrill Potapov spends a lot of time working with 12 year old kids who are trying to improve their reading, writing, comprehension, and analytical skills. In this talk, he explores a remarkable method of speed reading, called Spritz, that promises to let you “read Harry Potter in three hours” with full understanding and recall. Could such a promise possibly be true? -Gary
Heart Rate Variability, Body Metrics, and Cognitive Function by Justin Lawler. This is a great examination of how Justin’s HRV measurements correlate to all other personal data he has collected. -Steven
Using Spectrograms to Visualize Heart Rate Variability by Randy Sargent
Randy’s idea about using spectrograms, normally used for audio signals, to create a portrait of your own time series data, is completely novel as far as I know. -Gary
Spurious Correlations by Tyler Vigen. An entertaining collection of unrelated facts that can be correlated with a high degree of confidence. -Steven
Hackers Diet, FIRECalc and weight loss by u/Thebut_. This chart is a mess, but the idea behind it is fascinating. This reddit user was inspired by FIRECalc, a financial tool that “projects your future assets based on historical market data” and tried to apply it to his weight data. Instead of giving a single projection, the tool shows a range of possibilities. This is similar to how Baseball Prospectus’s PECOTA system uses a weighted range of possibilities (probability distribution) rather than a single guess (point estimate) for forecasting a prospect’s future performance. I would like to see more of this kind of thinking applied to personal data. -Steven
Darwin Tunes by Bob MacCallum, Armand Leroi, Matthias Mauch, Steve Welburn, and Carl Bussey. A fascinating project that treats pieces of music like organisms that can mate and reproduce based on listeners’ votes. These audio loops started off as random noise, but as the generations moved into the thousands, the presence of chords and higher order melodies emerged. At this point, there have been over 8700 generations. You can take part yourself! -Steven
Tobias Zimmer tracked what he ate and, in particular, what he didn’t eat. The image above comes from a series of ceramic plates that were created using generated graphics based on the crumbs he left. For more, see his Tumblr: Food-Data:
»Food Data« elevates an everyday occurrence to the realms of art. Minimalistic crumb compositions that emerge while eating every day, are enhanced by generated graphics, which refer to the topic of computerized data tracking of human behavior. The final plates encourage to contemplate on everyday life and to find beauty in daily routines, but at the same time remind of technological advancement and practices of (self-)surveillance, that doesn‘t even stop before the private ritual of eating.
Haunted By Data by Maciej Cegłowski. A keen sense of how things can go wrong is needed if we are to have any hope of – well, if we are to have any hope! This essay by Maciej Ceglowski about the highly toxic nature of large scale data aggregation is highly recommended.
How Your Device Knows Your Life through Images by Graham Templeton. This research demonstrating that an artificial neural network was able to train itself to correctly identify 83% of the time the activity that a person was engaged, just based on the images collected from that person’s lifelogging camera is especially interesting in light of Ceglowski’s talk.
Life Stress by Marco Altini. Marco reviews an exhilarating but stressful 15 months of his life through the lens of heart rate variability.
Body Metrics Under Stress by Justin Lawler. Another stress-related piece. Justin shows through data how his body responded to the stress of giving a talk about his lifelogging experiences at QSEU15.
Pathways Project by Mimi Onuoha. This project looked at what story could be told from a month’s worth of mobile phone data from four groups of people, each with a different type of relationship: co-workers, a couple, a family, and roommates. The charts are interactive and fascinating. As Onuoha writes:
…data visualizations add a level of abstraction over real world events; they gather the messiness of human life and render it in objective simplicity. In life, goodbyes can be heartbreaking affairs, painful for all involved. But on a map, a goodbye is as simple as one dot moving out of view.
The project’s data is available in this Github repository.
My Hamster’s Activity Index by /u/snootsboots
This reddit user used a motion sensor connected to a raspberry pi to make sure that his hamster is ok when he’s away. Here’s a picture of the hamster, if you’re curious. His name is Timmy
My internet’s median ping over time by /u/asecretsin. This a very simple chart, and a simple idea. What I like about it though is that it illustrates how just a little bit of logging and data visualization can reveal a pattern in one’s environment. It clearly shows that the response times slow down from 6pm to 10pm. I have a home office and it often felt like the internet slowed down around the time people starting getting off work.

As someone who still is not satisfied with any sleep tracking device or app that I have tried, I related to this dialogue from a tumblr called Zen.Sen.Life:
- Sleep Tracking App: I see you’re not violently throwing yourself around your bed, you must be in a deep sleep. Sweet dreams, buddy!
- Me: I’m actually still awake.
- Sleep Tracking App: But you’re lying still…
- Me: Because I’m trying to get to sleep.
- Sleep Tracking App: You mean you ARE asleep.
- Me: I really don’t.
- Sleep Tracking App: You’re going to have to trust me, I do this professionally and I know sleep when I see it, and I’m pretty sure you’re asleep right now.
- Me: I couldn’t be more awake.
- Sleep Tracking App: This is all a dream…
A man who tracked five years of sneezes might have a fix for your pollen allergy by Akshat Rathi. Thomas Blomseth Christiansen has spoken about tracking his sneezes at QS conferences. This article is a good telling of Thomas’s story.
Good tool with too small market can get a second chance – a hardware hack saves Zeo by Portabla Media. A short article on how Philipp Kalwies responded to the demise of Zeo. Since the sensors in the headband need to be replaced every three months and official supplies were dwindling on the secondary market, Philipp began to make his own and hopes to have this resource available to the small group of users who continue to get value from their Zeo devices.
