I support the napping for productivity without having artificial stimulants (OK, natural organic drugs) involved.

The studies likely involved mostly habitual users rather than unindoctrinated subjects, but from the abstracts' documentation it is difficult to be sure. Perhaps the researchers did not recognize the distinction and just selected random participants, therefore likely to include mostly habitual users.

When I was a caffeine addict (habitual user) I could also
sleep after ingestion.

In fact without a fix right before bedtime it was more difficult to get to sleep because nominal concentration level was unsatisfied, resulting more in agitation than identifiable craving.
A nice hit would actually help me relax.
I was not the only one who could relate to this as an indication of true addiction, where you need the substance just to be normal.

Complete withdrawal took a few weeks (of hellish tiredness, achiness, and irritability) but after this it was even easier to more alertly conduct high-stamina activities and out-perform my still-addicted colleagues without the toxic load on my system.

Sleep & nap much more productively without it after kicking the habit too.

Sure can write a lot better code when drug (addiction) free as well.

When I do feel it's necessary (never for marathon coding), a single cup of coffee (after I have already been awake 24hrs and need a little boost) naturally keeps my otherwise drug-free system awake for the next 24hrs easily which can be helpful for things like long-distance driving once or twice per year.
As an addict I would have needed two or three times my nominal habitual doses to feel as alert on those same lonely roads.

To me coding does not benefit from this type of non-stop alertness, even if you are working to exhaustion, when tiredness truly comes a plain nap is better whether it is after 6hrs, 12hrs, 20hrs, whatever, then freshly go into another session, exahustion relieved.

Same with driving too, but if the schedule is too tight, a couple times a year will not make you a habitual user like everyday dosage does.
I'd rather drive slow for long hours than exceed the speed limit, waste energy, and prematurely wear out my machinery.

YMMV [0] but just because everybody does caffeine won't make it good for you, especially in the long run.

Well ideally we wouldn't lose power to begin with but yes. The PW is essentially a powered wing to begin with, so losing power leaves you with just a wing. The real design benefit here is that with the powered wing, you can make the win extra thick. And I can tell you, that internal space is huge. Plenty of room for any kind of payload.

Exactly! A negative result is not a failed experiment, it's a successful experiment. Think of all the 0's and 1's in your computer files - now imagine if someone just deleted all the 0's because they were boring. Negative results have just as much information as positive results, if you did the experiment right.

I'm not asking to try the case for them. I'd simply like to come to my own conclusion.
This really isn't such a horrible comment. It illustrates nicely that "common sense" is often wrong. There was a similar reaction when radioactive material was stolen in Mexico. People said it should have been escorted with armed guards. But in truth, shipping radioactive material is extremely common. Three million packages of radioactive materials are shipped each year in the U.S. alone. So while it seems like radioactive shipments should have armed guards, it isn't actually practical.

In this case, the truth is that anyone who has the capability to disrupt these cables already knows where they are. But that isn't necessarily intuitively obvious. This is a reminder to all of us that we shouldn't blindly trust intuition, but should try to find numbers or other hard data to back it up.
If ever I run a large business I hope I'm good enough to warrant that sort of loyalty and respect from my employees. That's something to aspire to.

How many hours of this developers time did you take up? Refunds don't exist unless you're willing to go to court and if the work was actually damaging to your company. You took a risk and you have to pay for at least the time of the developer if not their skill (since it wasn't up to your expectations).

In any case, you built the app from the scratch. The previous dev with their previous crappy code base can go cry somewhere else and stop making defamatory comments about your company.

I think serious Linux users going for mouse-free and / or using tiling window managers designate one of the Windows / menu / command / Apple keys as "window manager" key as well.

It's nice though that MS made this a default for Windows, while Linux still wants to ignore that MS ever managed to get those keys added to the keyboard. I've been using them for years, one as wm-key and the other as compose key to be able to write special characters (ë, ø, €, etc.) easily on a default qwerty keyboard. That still leaves one spare key on most keyboards

Todd Bol of Little Free Library gave a talk at TEDxFargo [1] last year. After the event I had the opportunity to chat with him a bit.

This topic of book quality degradation or opinionated materials added. He mentioned that while people do put in weird books or those with an agenda, you do curate your own library. More often than not, people will quit putting in junk after you clear them out a couple times.

A lot of times where there is an unregulated shelf for book trading (in hostels, bnb's, some community type centers) you do end up with low quality discards. Somebody needs to be responsible to weed out junk and add make additional books available.

The nice thing about it is you can curate it to your interests or whatever is relevant to your community. In the talk he mentions a cooking based library with a herb garden that you can also trim for the recipes. He also talks about ones based around children's books and interests.

It is in no way a 'set it and forget it' type of project. Some work in curating the materials is required.

This was a very useless "enhancement" to the search page and its sole purpose was to get more people signed up for G+ so they names and photos can be shown in search.

For most users, a picture and name dont mean anything unless they are super famous or is an author the user follows closely. if the user loves that author, the user already knows which website is credible because authors typically are on one site they publish. some cross publish but in most cases, there is a primary site. so the user intrinsically knows what is a trustworthy result.

even if we were to assign some weight to the author, as a user I dont need to know who wrote it. I trust Google to present me with trustworthy articles instead of wasting space and distracting my attention from the results.

this was a very horrible move on Google's part along with a bunch of other useless "enhancements"

But if the steak comes, even if you say to a friend "this steak looks lovely" (eg using alpha for a product briefing with investors) and when you cut in to it it's raw or has a cyst or something then you send it back, you don't pay for it then. That's the implied contract at work.

What's the implied contract here? Well we shouldn't need to ask, there should be an actual contract to refer to.
Who owns London?
One of the most depressing things I've heard in my life came from a VC type around 2007.

He basically told me straight up that working hard to build a real business with real value was a sucker's game. Every example he'd seen of people making real money was -- as he put it -- from "equity plays."

By equity plays he basically meant this kind of thing. I started calling it "hype, leverage, flip." If it were just a lot of harmless hot air that would be one thing, but what's really happening here is wealth transfer from honest and productive sectors of the economy and from the long-term savings of the population (e.g. pensions) into the chip stacks of high stakes gamblers.

Throughout history, gambling has always been one of the favored pastimes of decadent nobilities. Today's gambling is particularly clever, as it has the outward appearance of productive work. I cannot help but see today's financial elite in powdered wigs, and probably merkins too. Guillotines can't be far behind.

Luckily there are a few honest VCs and angels, as well as a new emerging financial system built around crowd funding and peer to peer finance. That's the future. When the guillotines fall -- literally or metaphorically -- the new distributed financial system will take over in the same way that mercantile and industrial financial systems took over after the fall of Medieval feudalism.

I once recorded a band. I thought we made a pretty good record, but they said they were unhappy and didn't want to pay me. Then they released the record.

My point: this kind of thing isn't limited to software development. If you benefit from someone else's work, pay them.
Not quite. As information they are much, much weaker. There are an almost unlimited number of negative results, and only a few positive ones. Imagine you are tuning a radio with a dial. Nobody wants to hear 'static at 100.3MHz! Static at 100.31MHz! Static at 100.32MHz' They'd rather hear 'Signal at 103.5MHz!'
Three things I could think of:
1. Cost
2. Time
3. Hiring Process

Elaborating further:
Cost - Providing feedback to each applicant is a costly process, that would normally entail multiple systems (people, resources) to provide feedback that is going to be specifically helpful to the individual.

Time - Crafting feedback takes time. An automated process would generally be regarded as more backward, especially from the person receiving the feedback.

Hiring Process - Given the two reasons above, organizations tend to exclude this practice (particularly for large organizations who may need to process hundreds or thousands of applicants for a certain posting).

Conspiracy nuts have a way of being right about the particulars and pretty astute at spotting trends while simultaneously being bat-dookie bozo about the overarching mechanisms behind it.

All the surveillance state stuff that the wacky Bill Cooper types were ranting and raving about in the 90s has all come to pass, often in weirder and more alarming ways than they predicted. Yet I'm still waiting for my 666 stamp, nor do I see very much Masonic influence in things.

A conspiracy theorist is kind of an investigative journalist with bad epistemology and a poor understanding of how the world really works. They see the smoke and correctly extrapolate the fire, but they think fire is phlogeston excreted by underpants gnomes.

The reason they're so often right probably boils down to the fact that as loony outsiders they've got no vested interest in towing the official party line. So they're able to say really contrarian things and not give a damn. According to Pravda, stocks always go up. Saying different is not a good way to advance your career in the Party.

>Up until early 20th century philosophers had material contributions to make to the physical sciences

I think what changed was physics became much harder to understand. Pre Einstein it was fairly easy for someone without much physics training to grasp Newtonian stuff. With the advent of general relativity and quantum mechanics it became hard to understand without years of study of physics which most philosophers do not have which led to their work being not very useful to the physicists. However philosophical insights by people who do understand the physics can be good in my opinion.

Feynman seemed good, for example. Simple stuff

The lord, the bishop, and the harlot: an etymological fallacy
I actually recommend strongly against this book. It teaches things new people to Rails, let alone people new to programming, don't need to be messing with so early on. I'm mainly talking about the use of RSpec and some of the outdated Rails idioms.

For myself and a few people I've mentored, Agile Web Development with Rails[0] has yielded much better results. If they follow that up with Eloquent Ruby[1] they will be golden and well ahead of their peers with similar experience.

This book single-handedly breeds the "I'm a Rails Programmer!" that write terribly awful Ruby code that we all know and hate.

I don't mean to discredit Michael's hard work. Writing and maintaining a book like this is a huge achievement that I'm probably not capable of. I also appreciate that his book is at least bringing people into the Rails ecosystem. I just can't recommend it over others.

i3 only has two modes by default. You can create whatever modes in i3 you like.

set $mediamenu "media: [spc] play/pause [p] prev [n] next"

mode $mediamenu {
bindsym space exec "playerctl play-pause; i3-msg mode default"
bindsym p exec "playerctl previous"
bindsym n exec "playerctl next"
bindsym Escape mode "default"
bindsym $mod+m mode "default"
}

bindsym $mod+m mode $mediamenu

Now $mod+m will enter 'media' mode, with its own set of keybindings.

I wonder why they didn't just lay them along the alcan highway? Surely that would have been a zillion times cheaper.
Rockets are inefficient atmospheric vehicles. You use rockets to get to space because you need to get out of the atmosphere as quickly as possible.

You also use them for single-use things (missiles) because the value in making a thing blow up at a distance is a lot higher (a $5 million dollar tank, for example) then the rocket itself.

But they're terrible for when you're into purely shifting mass. Air-breathing propulsion with aerofoils is absurdly better. It's why hypersonic flight and things like the Skylon are a big deal.
Better is to "ping uz.". Otherwise you'll trigger a lookup in the local domain, which might take some time to fail.
Agreed - the other day I was getting nostalgic for this kind of thing, when ISP's gave you 2MB of space and an ftp account to do whatever you wanted with. I kind of wish that model had continued; maybe $45 a month for broadband and a microvps included for hosting your own stuff.

Divorce: The Fk You That Keeps on Giving
When you need to cover your ass, providing feedback for rejection is always a bad idea. If you're dealing with a pushy sales person and you give them a reason why you're saying no, you've given them something to work with. They can debate whether your reason is legitimate. They can promise to meet that criteria, then you have no reason to say no. The same can apply in ending or rejecting a romantic relationship. If you give a reason, it can create an expectation that when the reason changes, the rejection will change as well.

Put this in a legal context and giving a reason for rejection is just asking for trouble. First of all, the rejected candidate could argue that your reason was illegal. Second, they could argue you were misinformed, so the reason is not legitimate. Finally, they could argue they've changed, so you have to reconsider them, since your stated reason no longer applies.

In all these cases, it's easiest to provide no reason whatsoever. (See also Miss Manners, who frequently has advised repeating a meaningless, "No, because I can't; I can't because I won't be able to" type response until the other person gives up.) Giving a reason creates a focus for an argument. No reason, no argument, just the other person incessantly begging for a reason, which is never going to make them look good.

No, refueling is not an option.

- There is no way for the satellites to reach the ISS
- There is no way for the ISS or the crew to reach the satellites
- The ISS does not carry equipment to refuel satellites
- The satellites are not equiped to be refueled in space

etc...

You should now edit this comment, since the link has been replaced. I was quite confused until I compared the links.
I think in order to perform a refueling you would have to match orbits first. Given the expense of getting the necessary fuel up there (even if ISS uses fuel on-hand, it would have to be replenished at expense), matching orbits, and correcting the orbits, it would probably be easier to just launch new satellites.
Or not enough airspeed, which is the most common stall condition real pilots face (caused by a variety of scenarios such as too much altitude, runway approach too slow, etc).
That is plain impossible. To change the shape or the inclination of the orbit takes a lot of fuel (change of 1km/s is a good order of order of magnitude even if it is more of an upper bound).

Moreover, if you have to carry fuel for somebody else it gets that much harder to accelerate/decelerate like that.
AFAIK, it was already established they do not have enough fuel to circularize the orbit at the correct altitude, let alone correct the inclination (which takes large amounts of fuel).

I like that it says "studies show" that null results are rarely published. In fact, from my friends who are in the social scientists, that's just how the journals operate.

Sure, null results are meaningless for complex hypotheses, but when testing a very narrow variable with a well-designed experiment, a null result is actually a very important result.
