It really depends on where you want to go with it. I found early on that I learned most by figuring out how to achieve self contained blocks of functionality to accomplish a more elaborate task. For example, to build a tape following robot you need to run the motors, read some IR sensors, implement some kind of PID control, build some kind of regulated power supply, etc. (I learned least from solving circuit problems out of a textbook).

Each of those tasks can pretty well be accomplished by building standalone circuits, none of which are particularly complicated. In the process of building and debugging each one, you'll find you need to figure out how some of the more basic building blocks of electronics work, for example, capacitors, LEDs, opamps, transistors. There are a huge amount of resources out there to learn from. For anything related to arduinos or microcontrollers, just google it. I don't mean to sound condescending, it really is something that can be googled very easily with relatively high quality results (unlike some other areas of electronics, such as analog amplifier design). For some more theoretical stuff, I suggest you check out MIT OpenCourseware as well as video lectures from Standford on youtube. I blundered my way through a physics degree and an electrical engineering degree using those sites. For a more gentle introduction to some electronics concepts and applications, maybe check out this:
http://electronics.wisc-online.com/Category.aspx?ID=3

Now the bad news. You can do a lot of futzing around with arduinos and leds, and that's great, but you'll soon find out that it's interaction with sensors and actuators that makes electronics interesting. To do that you will find that you need to build/use external 'hard' circuits, and to do that you will eventually need an oscilloscope. You really can't get too far in the field without one, even if it's just a hacked sound card and audio cable. I say 'bad news' because a new benchtop scope is pretty expensive. A breadboard, some wires and a soldering iron don't hurt either ;-) For components and data sheets, digikey.com and octopart.com are your friends. For breakout boards and other hobbyist accessories, sparkfun.org and adafruit.com are your friends. There's also a arduino plugin for sublimetext, in case you're like me and can't stand using that atrocious java UI.
> Still find it hilarious how so many people still don't understand that a caloric deficit or surplus is the #1 thing to do when trying to cut or bulk.

Don't you think that there's more to human nutrition than "cut" or "bulk"?
> considering this a pure caloric issue and not a food quality issue

I'm sure this will get a bunch of "but calories in calories out" replies - nobody is doubting the laws of thermodynamics, but there is an world of difference being, say, 400kcal under your TDEE eating "better" foods versus junk, both in terms of your mental outlook, how your body will look at the end, and whether you will stick to the diet and therefore succeed at your weight loss goals.

You need to learn about old age and how it effects the brain.

That's exactly his point. The approach of merely counting calories ignores the fact that some foods such as diet soda are low in calories but can have an effect on body composition.

You shouldn't just "eat less" you should "eat better", and that means eating an appropriate amount of healthy good.
I won't disagree with that - if I'm making wrong nutritional choices, let them be as tasty as possible!
And eating better is far more important than eating less.
It's tough to lose weight. I've had success lowering my calorie intake.

I find that only implementing one change at a time conserves my willpower so that I'm more likely to succeed. I'll either up my exercise a couple weeks before I start cutting the calories or cut calories then wait a few weeks before introducing exercise.

Controlling what I eat, for me at least, is easier than upping my exercise levels.
In real world, ad hominem arguments make more sense that they are sometimes given credit.

Of course, in an ideal world, we should be able to just judge someone's argument based on its own merit; however, in practice, an 99% arguments (pretty much everything that is not a mathematical proof?) will cite external facts and references. This creates an ample opportunity for manipulation for someone dishonest and hence credibility is important.

If you want to lose weight and be healthy - eat little and eat healthy.

If you want to lose weight and don't care too much for your health - eat little.

If you want to be healthy - eat healthy.

If you just don't care - eat whatever you like.

This also applies to the user trying to configure it. For all the reasons listed in "weland"'s sibling comment, this is hard to learn. If something doesn't work in polkit, and you're not completely familiar with it, it's very hard to make it work.
Have you tried that though? I'd say the reason why people associate bacon with being fat is because people that overeat bacon tend to overeat junk food, sugary snacks, industrial bakery and drink litres of sodas. Truth is though, that over the last few years more and more studies are disproving[0] the connection of saturated fat with obesity and heart disease.

The correct solution to this problem is to tax the rental income and hand that money to low income households. It would create a balance of correct market prices and allowing low income people to stay.

Just letting the price float and pushing low income people out creates an unbalanced society where a class divide builds up over time. Modern housing policy in the UK is to mix social housing with regular housing developments, having social housing all grouped into one location was a catastrophically bad idea from the post war era.
If my opinion on the matter is welcome here, I would recommend against AoE. It is, indeed, the 'bible' of electronics, but it's also huge, expensive, and not terribly helpful for someone who isn't in school for electronics. Great once you know a little more, though.
That is a truism.

Of course there is, but getting your priorities wrong is counter productive. Set the calories first based on your goal to cut/maintain/bulk, then you automatically figure out that junk food is a calorie thief and unconsciously start eating quality food, then you start adjusting your macros for body recomposition and the list goes on forever. Calories are #1 though.
"you [sic] BMR[0] is 2-3 times higher than your all other energy expenditures"

Maybe if you work sitting in an office and never go play outside or lift weights.

Try lifting bricks or digging ditches or cutting wood all day and that BMR is just the beginning. Or climb a nice mountain or go on a hard bike ride or get nice and ripped and keep those muscles up.

In the evolutionary environment where you were shaped everybody worked outdoors and sweated. If your BMR is most of your energy expenditure, you're not living the life you're adapted to.

[0] Basal metabolic rate -- the energy you'd expend on the couch watching teevee all day.
Intuitively I do this all the time. Whenever I have pressing life questions I go on a walk and from time to time think about the options I can take. I find for myself that it's easier to see the bigger picture than when I'm sitting. Perhaps it's also that the analogy of moving forward in life and moving forward in real-time helps.

In the case of this study, I'd guess that walking excites the supplementary, pre-motor and the motor cortex, as well as some attentional processes devoted to it from the prefrontal cortex (PFC) compared to just sitting. If this is the case, then I have two hypotheses why this works. (1) Because the motor cortices are involved, the PFC are easier excited as well. (2) Since some attentional processes are devoted to walking it's easier to think in a divergent manner, because there's less conscious and sub-conscious room for convergent thinking.

I don't know how to test hypothesis 1, but hypothesis 2 has probably already been tested in cognitive science (I just didn't look it up). Reports where people get distractor tasks in the experimental group and a similar task as the main task in the control group probably exists.

What do you think?

There very nearly is no such thing as healthy food. There is only food containing various contents in varying amounts.
Sure, but they don't vary that much between - and + 1 stddev. Eating 500 kcal / day less (or more) will affect the weight of pretty much everybody, over several months.
This is true, but: when I exercise regularly, I find that I am less hungry and eat less. Anyone here made the same experience?

The increase is 10% or so IIRC. So still not that significant. In our modern life most of the energy spent is to keep you alive.

And you have upper limit on your BMR - you have to maintain a steady temp. We just cannot dissipate much more than currently before cooking ourselves medium rare.

Yeah, the GP sounds like my wife - "I need to lose weight, better buy two extra broccoli's". Uh no, to lose weight, you need to eat less, not more - just leave that bag of crisps and forget about the broccoli.
So true. I've found that Intermittent fasting + a 500cal deficit (below TDEE) is the easiest/most-effective way because it fits into my life-style as a programmer. I eat my last meal at 8PM and go to bed at 1-2AM. So not eating anything until 1PM the next day is a breeze (with a couple of cups of coffee in the morning). I've lost 20 pounds over the last 3 months with zero exercise.

LastPass Was Hacked – Change Your Master Password Now
After I bought my first Arduino, I did the pulsating LED tutorial, put it in a box and that was it.

Then, by accident, I found a "37 sensor kit" for Arduino on dx.com, and that was a game changer.

And I think that's the problem with getting hooked: pulsating LEDs are fun for a few seconds, robots are interesting but waaay too complex for starting out, but just having some sensors and simple tasks (measure the temperature, send it to another arduino hooked up to a PC, store the data, make a pretty web page and voila you have ambient info) is better.
You can also use another encryption mechanism like GPG or something akin to TrueCrypt's (not sure how people feel about using TrueCrypt 7.1a these days) encrypted hidden containers to hold your KeePass database on your cloud storage, which itself would also be encrypted and need a key file.

This way you have three or four separate, strong barriers of entry to your KeePass database.
Nothing I said was "indignant."

Just stating that there's other things besides such strict calorie counting. On top of the fact that when practically put into play for people in real life, "calorie counting" feels restrictive, doesn't account for satiety (which then causes hunger & tends to lead to binges).

Re: better - tons of vegetables, high quality meats, low-sugar fruits, nuts and seeds. Carbs when-appropriate pre/post workout.
Blackboards are better, but the argument about superior chalk is pretty dumb.

I had/used everything from blackboards to digital whiteboards. I still like
blackboards better, but it's only going to last as long as digital displays
improve.

Blackboards lasts forever. Whiteboards, especially the cheap ones, inevitably
start to have stains that you cannot clean without some solvent.

Blackboards work with any chalk, essentially. You have to be careful about
whiteboard markers, because many stink to oblivion (I get asthma out of them),
and many others don't erase properly. One of the best markers I tried are the
water-based made from Edding, but they're harder to clean, and you have to
clean within a couple of hours in order to be able to clean at all. Chalk, on
the other hand, lasts forever and can always be cleaned. If you want a perfect
blackboard, just use a damp cloth.

There's this illusion that whiteboards are cleaner. Actually, they're not.
Whiteboard "dry" markers work by depositing a fine powder on the surface. It's
initially suspended in a liquid, and then sticks on the whiteboard "ideally"
only due to electrostatic tension. Dry marker powder is often toxic, the
suspension liquid is often toxic (especially when you breathe it), and the
powder sticks fucng everywhere. If you're careful when erasing, a blackboard
can be kept very clean. I have one in the kitchen.

The markers are expensive. Especially when you want the good, water-based ones.
I often have to order those. Chalk is inexpensive, I can buy it anywhere.

Why the hell are we using whiteboards??

I built several whiteboards myself. They suck. The best approach to a
whiteboard is buying a piece of glass the size you want, and gluing a piece of
white adhesive plastic on the back side. Dry marker on the glass always
cleans. You might get stains if you leave the marker for days, but they come
off easily, with just water.

Now what.. digital whiteboards. It's a love-hate relationship. They're
completely clean, which is what I like about them, but there are many downsides
too. You need power, which means that you need to switch the screen off. A
white/blackboard on the other hand shows you stuff all the time.

The screen is large, but the pixels are too large. The DPI, at close distance,
is ridiculous. They're also too bright when seen at close distance. There's
glare. The "pens" suck. But if you did the same with some e-ink technology, I
would switch to digital whiteboards instantly, as it would solve all these
problems at once. It looks like a dream application where the price of the
display wouldn't matter much (ardesia costs a fortune nowdays anyway).

I had to use at some point an Epson projector which had some whiteboard
capability on it. The pen had an infrared sensor/reflector on top, which meant
that you had to hold the pen without making a shadow between the projector and
the pen. Who's the idiot that thought this would work??

It was around before the Debian Technical Committee made its decision.

How to read a technical book? (2003)
You want to look for 'author attribution' as your keyword.

There are 2 main ways for assessing author attribution. One is through stylistic markers, where you look for a set of predefined features. The is average length per paragraph, or the number of times 'whenever' is used. This is highly language dependant.

The other way is through character n-gram analysis. You chose for which N you want to harvest N-grams and your author profile is the frequency of top 2000 n-grams and you compare this profile with a documents top 2000 n-grams and the profile with the shortest distance is your match.

Robert Layton has a tutorial and some code on N-gram attribution on Github:

"All other factors being equal, a person burning 2500 kcal per day and consuming 2000 would be worse off than if they burn 3000 kcal and consume 2500."

I have tried every possible generous interpretation of this that I can think of, but I just have to ask I guess: what's the idea behind this?
> Eating 3000kcal of "quality food" every day will still make you gross fat and give you heart problems.

Well, depending on your size, activity level and metabolism - maybe. Maybe not.

> Insulin is essential for muscle building.

Sure - post workout. If you get a massive insulin spike first thing in the morning (juice plus bagels and cereal), at the exact time where your body's hormone levels are optimal, you're not doing yourself any favors.

I'm not vilifying any hormones - but there are optimal times to take advantages of the benefits of specific ones (and optimal times to make sure they're not spiking all over the place).
If I know I'll go for a run I am very hesistant to eat heavily, as I know I'll regret it.

The more you exercise the more you push back heavy/unproductive meals in your schedule. You just know if you eat wrongly you won't be able to keep up with your own pace of execise.

Eating and execise seem deeply connected to me. Certainly it is hard to put this kind of thinking into a controlled randomized trial.
> eating "better" almost always puts "better" out of reach of low-income families.

I learned to cook cheap, unprocessed, healthy food as a student, in order to save money. A big bag of potatoes doesn't cost much and can make the bulk portion of many meals. I currently cook a lot of beans in my pressure cooker - easy, cheap and healthy.

Admittedly, the preparation time increases, which may be a problem for lower income families, but I always see the cost argument as false.

One major problem with the standard BMI definitions is that any athlete in a sport that vaguely requires muscles will be classed as 'overweight' or 'obese'.

Although there may be some justification for this categorisation, these are people we normally consider at the peak of fitness.

One of the best things you can do for long-term health outcomes is to follow a strength training programme. For an average person, that may result in weight gain via muscle. This is not a bad thing.
