Awesome work! Looks like there's a great community growing around the esp8266. I'll need to check it out myself sometime.

The cynic in me says because they have the brand name and they can be stingy.

The reality is likely that they are conveying their values through the investment terms. They want startups to be lean, fast, and high growth. Money makes you lazy. They're saying they'll teach you the actually valuable stuff in the program. YC also says they'll help you raise more investment money if you need it, which is true, I suppose...

I agree that caffeine powder isn't worth buying because it tends to come in large sizes and is hard to measure out. I'd recommend caffeine pills/tablets, though. Much easier than brewing some coffee or tea, and you can manage dosages more easily.

I would pay a significant amount of money for pentadactyl + Tree Style Tabs that just worked, without bugs. It's a significant part of my workflow, and I'm not sure if either will survive XUL deprecation. :(

In vim, j and k will only move the cursor between lines that exist, and the screen will follow the cursor. You can scroll the screen past the end of the file using ctrl+e and ctrl+y, but it's annoying.

My school requires a financial commitment by mid-August so unfortunately, I'm not able to apply without taking a risk. Something to consider if you continue with the program.

The figure I've seen quoted in the context of embedded systems is 1 bit flip a month.

I don't know how practical that is; FPGAs are very efficient, but they won't come close to the raw computational power of a GPU. Many moons ago, the dream was to have a configurable FPGA in every computer, but GPUs ended up winning out due to games, among other reasons.

Adapteva [0] is a startup doing cool things with multi core parallel coprocessors. From their interview on The Amp Hour [1], it seems like their target niche is parallelisable loads that aren't IO constrained, such as computer vision and video processing. Chunks of a video frame don't need to talk to each other.

There has been some controversy over the years regarding Congress and insider trading:

Agreed. StarCraft is not as hard as people make it out to be. The path to Masters is pretty straightforward and achievable in under 3 hours a day. You just need to be smart about how you practice.

That Circadia device looks way too large to be comfortable. With some more engineering, it could have been made much smaller. Also, in the removal picture the battery seems to be bulging rather dangerously..

Battery maintenance and safety is a big concern. It's not easy to get at these devices once they're inside you. I know pacemakers use Lithium-Iodine battery chemistry, which is much safer and longer-lasting than Lithium-Ion.

Additionally, if it's just measuring pulse and heat, how much value does it provide over a smartwatch? My Moto 360 already takes regular heartbeat measurements and I can (crudely) map it next to my sleeping patterns measured from the accelerometer[0]. (Interestingly, there's a fairly high correlation between the two!)

I appreciate the vision of biohacking, but this device doesn't seem to provide much advantage over an external device, while introducing a whole bunch more inconvenience and risk.

You may be interested in this episode of The Amp Hour podcast, where they talk about powerline analysis attacks: http://www.theamphour.com/239-an-interview-with-colin-oflynn....

In general, it is like many other side channel attacks, where you can use the data to put constraints on the search space for a brute force attack.

That's what I used in high school, but they're not very good value. You'd often need to pay a few bucks in fees just to use a $20 prepaid Visa card.

Example of this in action: https://youtu.be/I5QyNA6H6rY

When will I be able to do anything similar?

I enjoy using Cardiogram but there doesn't seem to be any good way to export or view my data outside the app, unless I missed it. Additionally, I can't store or view any data unless I'm connected to the internet.

Luckily, I know of a scheme to compress the address 100%! ;)

The phantom wrist vibrations will come eventually... I get them whenever the leather strap creaks.

I've been using an ErgoDox for 5 months and I regularly switch between it and a laptop. Switching isn't too bad, especially since I have ctrl bound to the caps lock key on both.

I think you need to look at it holistically and place yourself in the shoes of your audience. I imagine an example of a "rational" purchase to be something like searching for a good (eg. headphones) on Amazon and comparing prices between brands. A buyer will try to research and justify their purchase, and the cents may help push them over the edge and convince them that they've "done their homework". Meanwhile, an example of the syllable tactic is a restaurant menu. When I order from a menu, I'm time constrained and forced into a decision. I ask myself internally: "Would I get 19 dollar value from this meal?", and if the answer is "Yes", I'll order it.

A good programmer that writes less lines of code is more efficient than a bad programmer that writes more to do the same work, because you pay each per line of code. A library that allows both to write less lines of code will increase efficiency for everyone.

It makes sense to talk about lines of code when thinking about engineering hour efficiency. It costs the same amount for a programmer to write one line of C as one line of Assembly, and the rate of bugs tracks lines of code as well. The underlying libraries and abstractions should be considered if you're thinking about computing efficiency.

Comparing battery technology with Moore's Law is just ridiculous.

Every year, there are big claims of revolutionary, new battery technology, but they never seem to reach the market. We're going to have to live with incremental improvements on Li-Ion (which companies like Tesla and Apple seem to be making some strides in) until alternative technologies mature, which I suspect will take years.

>Brag until you Fail

>Share your idea, it’ll validate (or invalidate it), shape it and most importantly, commit you to it. We don’t want to let people down and we do want to save face, so tell people what you’re working on.

I'm not sure if I agree with this last point. Studies have consistently shown that discussing a goal with others reduces your motivation to actually meet the goal[0]. I've found this to be true in my own experience with side projects. I'll spend a few days excitedly discussing the details of some idea with my friends online, and then never end up finishing the project.

Social pressure does work, but it's likely better for more definite goals. You could tell your friend "You know, I think I'll run that marathon with you next month," and be obligated to prepare for it. However, side projects are mostly self-motivated and there's no use sharing all your excitement with friends instead of working on something tangible to show.

I take piracetam/pramiracetam/noopept on and off and cycle between caffeine+l-theanine and nicotine. Some non-nootropic supplements I take are fish oil, Vitamin D3, and melatonin. Here are some of my anecdotes.

::Piracetam

I haven't been able to get very consistent results with piracetam, but it's definitely not placebo. I've found that piracetam is hit-or-miss for a lot of people. Some are very sensitive and only need 500mg, while others, like myself, need somewhere around 10g, and it just doesn't work for others. When I started, the effects were fantastic: I had increased focus, more vivid dreams, and was more outgoing and personable when I'm normally introverted. However, after about 2 weeks of regular usage, much of the effect went away. This seems consistent with some other peoples' experiences with piracetam on the web. It seems to be having more effect now after a 2 month break, so it may just be tolerance. Also, @StevePerkins implied that piracetam is illegal to purchase in the US, but it is still unscheduled and legal to buy in most countries.

::Pramiracetam/Noopept

These are much less subtle than piracetam.

I usually take between 200-500mg pramiracetam and it has the same focusing effect of piracetam, but with a stimulating effect as well. I haven't noticed any tolerance issues, even with a period of regular use.

With noopept, I only felt any effects when consuming around 5mg sublingually. It's not a racetam so it's a bit riskier, in my opinion. I felt focused without any stimulating effects and I found it helpful for exams. Some people have reported short term memory issues with higher doses.

::Caffeine/L-theanine

This really is one of the best nootropics around if you can reduce your tolerance. Just caffeine makes me feel jittery, but taking it 1:1 with l-theanine makes me feel calm, focused, and energetic.

::Nicotine

I cycle this with caffeine to reduce tolerance. I use 2mg gums, and it works pretty well. It feels like caffeine with the edge taken off.

Like others have said, the benefits of nootropics are marginal compared to the low hanging fruit of sleep, exercise, and diet. If you're interested, just do your homework beforehand and balance the risks with the benefits. Everybody's different; find out which ones work and don't work for you, at what dosages. I think the racetams are relatively less risky, but they are psychoactive at high dosages, and there have not been studies on their long term effects over several years.

I hope Freescale's openness with their datasheets and sample policy survive the merger. It seems NXP is the one consuming Freescale, however.

The benefits that companies provide to salaried employees (healthcare, etc.) end up being more than 40% of the pay they actually see anyways. So in the end, the pay is comparable.

Everything exists on a continuum of accessibility. People hold conversations in public all the time, but they don't expect anyone to be recording and publishing that information. The issue of the right to privacy becomes a bit more sticky on the web where information is easy to transmit and store, but I wouldn't call it ignorant. It's people trying to apply an older philosophy on privacy to the Internet.
