randlet··on Graphing when your Facebook friends are awake
Yep. Love HighCharts and HighStock in particular which allows you to create wonderful time series charts.
randlet··on Custom resume from someone who wanted to work at Airbnb (2015)
It looks like this from earlier in 2015 and there's a follow up post on her blog[1]. Ultimately she didn't get a job at AirBNB but seems like she did end up landing a job elsewhere as a result.

randlet··on Our Medical Data Must Become Free
On a related note I recently had some lab work done and was dumbfounded when the nurse looking after me told me I could now sign up on their website[1] and access my results as soon as the tests were finished being analyzed. Sure enough, less than 24 hours later I was able to log in and see the results of all my tests (or download a pdf) and whether they were in the normal range or not. The site even has trending built in so you can plot results over time for repeated tests.

Being able to print out your results and take them with you to the doctors so you both are on a level footing with respect to your health information is very empowering.

If you're a Canadian in Ontario or B.C. I heartily recommend using their labs[2].

randlet··on Olbers’ Paradox: Why Is the Sky Dark at Night? (2000)
Stars fuse light elements it into heavier elements. Eventually all the lighter elements will be used up.
randlet··on Dragula: Drag and drop so simple it hurts
I know it's not 'cool' but the fact that this supports IE7+ makes it infinitely more useful to me personally.

Looks very very nice after a short play with the demo!

randlet··on Feynman’s Derivation of the Schrödinger Equation
It's been a long time now, but I pretty much agree with you. I really enjoyed Griffiths as an introduction but for reasons that escape me now I remember having a bad time with Shankar.
randlet··on Why do people put on differing amounts of weight?
Based on all this discussion I regret using the phrase "it's your fault" which sounds too aggressive. Instead I wish I just emphasized that regardless of biological and societal pressures everyone of us does possess the ability to control your weight. Specifically by accurately counting calories (with a food scale) and tracking your weight you can adjust your caloric intake to lose, gain or maintain weight.
randlet··on Why do people put on differing amounts of weight?
I certainly did not mean to imply that it was easy. Simple yes, easy? Hell no. (I lost 45lbs last year, not fun). Nor did I imply that someone was a lesser person for being overweight. However, I do believe if you want to change your weight you need to take responsibility for the things you can control.
randlet··on Why do people put on differing amounts of weight?
Where did the 1300 calories a day number come from? How big is the person that number is for? What is their activity level?
randlet··on Why do people put on differing amounts of weight?
It's tough to hear but no matter what your genetics or internal flora are, being overweight is still your fault. It may not be "fair" that someone puts on less weight than someone else eating the same diet, but ultimately you're the one responsible for maintaining your own weight (by controlling what you put in your mouth) no matter what the state of your gut microbes.

edit: not picking on you Onion2k...I end up commenting a lot on these stories because it really irks me when so many articles and people are looking for something external to blame for their weight problem. You may or may not be able to change your metabolism but you absolutely can change the number of calories you're consuming.

Mr Rumsfeld, it's cool that you're doing this and all but I believe the title you're looking for is "I Decided to Commission An App"!
randlet··on Angular 2 First App Post-Mortem

  I leveraged the Flux architecture powered by the 
  immensely popular Redux library. For a cleaner 
  integration with Angular 2’s injector and TypeScript’s 
  type system, I wrote a class-based wrapper around Redux
  that exposes state changes using RxJS observables. 
  Consumers can subscribe to these observables and use the 
  Store class to dispatch state-changing actions.
This reads like a Markov chain generated from a pool of top voted Hacker News Javascript submissions.

"Adulthood isn't about you, it's about your relationship to others."

Love it!

randlet··on The big data of bad driving, and how insurers plan to track every turn
My insurance company has no idea what the mileage is on my vehicles (they've never asked)...maybe they would require that info before tracking you? I don't know. A few thousand miles discrepancy should be very easy to explain away though.
randlet··on The big data of bad driving, and how insurers plan to track every turn
It is trivially easy to game too in some cases. My insurer wants to use your smart phone to do the tracking over a period of 6 months after which you no longer have to be tracked. Want to do some street racing every weekend? Just leave your phone at home and go wild. Drive gently on your commute every day until the 6 month period is up and then resume driving like a maniac.
randlet··on The big data of bad driving, and how insurers plan to track every turn
I had this exact same discussion with my insurance agent yesterday. I opted out but the agent had trouble understanding (or more likely I had trouble communicating the idea) that once everyone else takes the discount that I will no longer be paying "the normal price" but instead I will be paying a defacto penalty because I don't want to be tracked. "No, it will only ever be a discount!"
randlet··on Why I Captured This MRI of a Mother and Child
I'm not sure if you're trying to imply something negative about this project or not, but there are many many research MRI's around and it's not completely unreasonable to spare 15 min of MRI time for something like this.
randlet··on Controlling a motorcycle tachometer with a Raspberry Pi
You made the front page of HN... Hope you've got a rev limiter installed by tomorrow!
randlet··on A Quine in Fortran 90

    #!/usr/bin/env python2.7
    print open(__file__, 'r').read()
    
Seems like cheating!
randlet··on The rise and rise of headphones
I use etymotic in-ear headphones with the two-flange tips (I prefer the rubber flanges over foam) and they do a remarkable job at isolating from external noise, allowing me to listen to music at a quiet (read non hearing loss inducing) level.
randlet··on A Quine in Fortran 90
Enjoyed the article. It made me pine for the days when I had time to dedicate a day to just play with code.
randlet··on Meal frequency and timing in health and disease (2014)
Not sure I understand. Why would easy be a negative?
randlet··on Meal frequency and timing in health and disease (2014)
"Try weighing yourself before bed and when you wake up. You'll find you lose a pound or more for exhaling carbon in your sleep"

I've tried this a bunch of times and have seen up to two pounds difference on rare occasions!

A significant fraction of the weight loss is due to water loss though.

(and technically it's carbon dioxide, not "carbon", although with climate change being blamed on "carbon" we may have already lost the war on that misnomer!)

randlet··on Meal frequency and timing in health and disease (2014)
That's correct. Lots of people do 16/8 fasting. It's easy to get used to skipping breakfast and having your first meal 5 or 6 hours after you wake up and then only eat in the following 8 hour window.

I use intermittent fasting as a very effective way to keep my total daily caloric intake in check. If there are side benefits on health that is a cherry on top.

A typical day for me would be up at 7 am. 2 or 3 cups of strong black coffee until noon. I'll eat two main meals of ~800 calories at noon & 5:30pm and then sprinkle 1000 calories worth of snacks all throughout my eating window until 8pm. I stay very satiated all day in this fashion...much more so than if I were to eat breakfast first thing in the morning.

http://qatrackplus.com It's a self hosted Django app for tracking quality assurance data for radiation therapy centres (although it could easily be adapted for other purposes).

Same story for me. I run an open source project used by hospitals and I think I'm stuck supporting IE8 for another year or two.

randlet··on Infamous Software Bugs
Shielding a patient like this isn't really feasible. The half-value-layer of lead in a 6MegaVolt clinical beam is 17mm [1]. That is, even with nearly an inch of lead shielding in place you'd still be delivering a large dose of radiation to healthy tissue.
