If you are interested in improved speed & distance tracking, take a look at this: http://fellrnr.com/wiki/GPS_Accuracy

There are some foot pods that will outperform GPS.


They don’t in real running. After seeing his page I got super excited. They’re really accurate at the pace you csalibrate them too, then drift quickly once that pace changes. So if you camlivrat them at 7:30min/mile, then run 8min/mile they’re pretty far off. Especially if you’re a distance running, or looking for accurate pacing. I’ve tested it both on marathons and tracks.

All current running watches and phone software uses single point calibrations. Now if they curved fit 2 or 3 points....


Stryd is a calibration-free technology. Motion capture technology is used to precisely track the movement of the foot at different running speeds & on different terrains.


If I have seen further, it is by standing on the shoulders of giants.

If I knew the giants I stood on, it is by the work of Fossa.


The simplicity of this exploit demonstrates something profound. The most dangerous things in life are not hidden deep in the weeds. Rather, they stare us in the face in the most obvious spots. It isn't the unknown that presents the biggest threat. It is the known that we never gave a second look.


The cardinal rule of security is: you never, ever, trust anything the client sends.

This bypass is a perfect example. Although author doesn't mention which interception proxy he used, I'm 99% sure it was Burp. Replaying modified content is trivial.


Even with a free software tool like mitmproxy modifying requests is trivial. You don't even need Burp.


the free version of burp is completely capable of doing this, and so much more


>you never, ever, trust anything the client sends.

The author likely wrote code that correctly validates "for all security questions a correct answer is given" and just forgot about the part where "for-all propositions are trivially true of the empty set."

It's easy to read a for loop for what it's intended as - a loop - and not think about "what if we never enter it at all?"


If we think well, we need to have loops, we might be feeling despair right now, however array languages don't need loops! I can write:

    min test each args
and I can do the same in JavaScript, it's just uglier:

    args.map(test).reduce(function(x,y){return Math.min(x,y)})
Writing in a functional style makes this kind of programming slightly less onerous, but it still feels strange in languages that are a bad fit.


I've seen multiple major financial companies vulnerable to modification of the page that could be done entirely in inspect element.


Fiddler also has this capability


heart disease vs. terrorism.

it seems to be an unfortunate emergent behavior of groups of humans.


I noticed that if it's a fire that kills many people it's only a one day news; while if it's a bomb that kills one everybody's afraid.


It's not the number of casualties that scares people, but rather the nature of the threat.

Fires have existed for several millennia. Our ancestors who built and lived in the very first settlements suffered from their homes/stores occasionally burning down. We know what types of conditions increase risk of fires and we know how to minimize those risks and put the fires out when they occur.

Bombs on the other hand are unpredictable. They also cause their damage instantly and there is no way to minimize or prevent it. You can escape from a burning building, or if stuck, wrap a piece of wet cloth around your mouth to minimize the amount of smoke you breathe while you wait for rescue. You can't outrun an explosion.

That's why people are a lot more scared of bombs than they are of fires (or car accidents, for that matter, which kill many more people than both fires and bombs combined).


I think perception of danger = amount of times hearing people die from doing act / amount of times doing act.

So flying is much higher than diving:

People drive much more than they fly (a few times a year vs twice a day) and hear about air-crashes (9/11, Malaysia Airlines) more than car crashes.

It's the brain playing games with us


Availability bias is definitely one aspect, but I think a big part of it is also how easy it is to tell a story that separates oneself from the victims (this often takes the form of victim blaming, but not necessarily). It's easy to tell yourself the story of how heart attacks happen to people with different lifestyles or genetics, or how car crashes happen to drivers who are less attentive, or how violent crime happens to people who live in other neighborhoods. It's a lot harder to tell yourself the story of how you'll avoid the plane with the latent mechanical fault or how you'll never be at a gathering place that would make an attractive terrorist target.

The reason you see so many entrepreneurs come out of IMSA is that the students realize they can learn anything. You see the guy across from you ace a test or finish an assignment faster than you thought was possible. You know you are as good as your peers so you push yourself to reach that level.

Once you accomplish everything the school gives you, you want more. You think of new ideas and no longer constrain yourself to what is given to you. This is just one dynamic that happens here. A lot happens when you tell the most driven and brightest to "advance the human condition".


This is something that I'm uniquely qualified to comment on.

I am an IMSA alum who was by and large, a below average IMSA student during my first two years. However, I learned a lot just by being exposed to my very smart classmates. Eventually, in my senior year I matured and started to work harder and got good grades. Had I stayed at my original high school I would have skated through at the top of my classes without much adversity. Then, based on the average college dropout rate of students from my original high school, I would have faced adversity in college and not know what to do. IMSA is a big part of why I am where I am today.


This rings true. Many of us start out with very limiting notions of what's possible, and there's nothing like surrounding yourself with bright people to expand the envelope of what seems to be possible.

I attended a school very similar school to IMSA in the early 90's (the Mississippi School for Mathematics and Science), and it was probably the best thing that could have happened to me at that age. I had a pen pal at IMSA who, like me, was sys-admining the school's UNIX server, so it was fun to trade notes. I had plenty of other experiences later in life that expanded my notion of the possible, but attending that school certainly got me on the right path.


I buy into Thiel's ideas on higher education. I created a startup out of high school. It failed and I went to college the next year. However, the startup taught me more than I have learned in my first two years of school. Many of my CS classes are simply a rehashing of what I already know. In my experience, Thiel is mostly right. It is possible, easy, and cheap to educate yourself and turn it into startup. The problem is it requires a great deal of luck and savvy to turn the college-less path into a sustainable model.

Wearing the v-neck right now! Congrats.


I graduated high school last year and decided to forgo a $40,000 college to be an entrepreneur.

I regret nothing.

Unfortunately, my parents are doing the silliest thing imaginable and are forcing me to go to college now. I dread reading articles like this four years from now.
