Do you ignore medical advice because it is delivered by a nurse or CNA instead of the doctor himself? The CNA doesn't have experience prescribing medication, and is simply "parroting" information from the doctor. Does that make it less valid?

It depends. I know a couple of doctors personally, and so I double-check medical advice given to me (by nurses or others) with them. Some nurses give pretty awful advice. I have a permanent stiffness in one of my ankles because of crappy medical advice by a nurse.

Are you an electrical engineer with experience in RF interference and complex avionics? No? Then you have no more knowledge of the situation than the hostess "parroting" instructions. Any rationalization you have is simply an excuse for being impatient.

I have a Masters in Physics, and I built electronics circuits before - yes, I have more knowledge of RF interference than the air hostess parrotting instructions.

Beyond the knowledge, simple observation shows that there is no interference problem: most people don't know how to turn off their iPads and Kindles properly, or don't care. Probably about 1/4 of the passengers have one or more devices switched on during take-off and landing - more every month. And yet there has been no recorded increase in airplane crashes.

Also, I hate everyone who grabs their bag immediately and stands up in the aisle. You realize we have another five minutes before the door opens, right?

Yep - and I want to spend that five minutes able to focus my mind somewhere else (e.g. my phone) rather than glancing expectantly at the luggage rack waiting for my chance to scurry and pick up my bag. Once the line starts moving, I want to be one of those people who just moves - not one of those jerks who then proceeds to spend 30 seconds blocking the line to fish out their bag and slows everyone else down.

tl;dr: You're kinda an entitled jerk on airplanes, which is one of the reasons I absolutely hate flying. For whatever reason, people like to pretend that they are god's gift to man when flying on an airplane.

I've made it a policy to not read tl;dr;s. It's a recent thing. Did I miss something of value in there?
I did not down the post you replied to. I did downvote the your post that first replied to. I up voted the post where you said that you're not rude to airline staff.

I felt like I was forgetting 90% of the stuff I read in man pages too and I probably did. But reading them once showed me some of the possibilities those nifty little tools have. Sometimes when I approach a problem I remember one or two things I didn't know before. Even though I don't remember them exactly, I still know about their existence and can easily look them up again.

When I have some spare time on my hands I like to skim manuals for those features. Vim for example, I have been learning continuously ever since I first used it and I dare to say that by now, I know a bit about it. However, I never sat down trying to memorize everything but kept skimming the help every now and then and when I found something cool I just tried to start using it. Some things I've forgot, others stuck.

I guess that's just the way I learn.
Would love MacBook Air, but with no (transparent) background.
Actually, that is exactly why I like SV.

It's about the ecosystem, not the players. The kind of problems the author talks about are offshoots in an ecosystem that is built to develop and sustain massively huge ideas. This is not only expected but required to keep ecosystem healthy. Can you imagine if there were no such companies and only 15 ideal ones? It would make for a very unhealthy startup land because startup is about trying new things, ideal or not.
Can you describe a bit more about schematic.io? I quick google search didn't turn up much. What is this going to be?
You are horribly ill informed. Xbox Live, Hulu, all of those are at bit rates and quality roughly what a Sports offering would be doing, and work just fine. I'm not splitting hairs, you just have never worked with a CDN, or done any real work with a real budget. The tech and pipes to do this has been around for 7+ years.

Paranormal is a lazy word for me to use, since a scientific worldview doesn't have any unexplainable phenomena, only unexplained phenomena. Leave that word and its implications aside, and take this away: I feel comfortable saying (and you seem to agree) that what you're describing is far enough outside the practice of mainstream neuroscience that the same recommendation applies as if you were able to read minds.

1) Scientifically verify, carefully, for yourself, that you aren't simply delusional, and 2) Bring that scientific verification to the attention of researchers in the field, because they have been working their entire lives to find this sort of thing.
Kindles can be turned off; they also have an airplane mode. Kindles can send and receive WIFI and sometimes 3G traffic. Kindles are electronic devices.

Yeah, and most Kindle owners don't know that. I therefore assume that every single flight is a piece of very strong evidence that kindles, ipads and all that lot, do not interfere with avionics, because each flight of 200 contains at least 50 active devices that have not been properly switched off for take-off or landing.

Okay, that's something you should probably have mentioned earlier.

Given my long history on this forum, perhaps you should not have assumed that I'm some kind of inveterate asshole just because I didn't explicitly mention that I'm not.

They don't have the authority - that's the point. They merely enforce the (potentially dumb) rules given to them. The consequences to them and their employers for not enforcing the rules are severe. They might lose their job. Their company might be fined.

I'm not angry at the flight attendants or even the companies for that - though the companies could probably do more to lobby for a change of the rule, on behalf of their passengers. In fact, the companies are probably not entirely blameless in this, but that would require more digging to establish.

In general you don't want people to need to make assessments. Otherwise you get Ann saying it's fine for your kindle to be in sleep mode and Bob telling you you're going to be taken off the plane unless you turn it off. And if you do give these people that power you also need to give them the training, and the wage rise for the increased responsibility. That cost goes directly to you when you buy a ticket.

On the contrary - if they don't need to make assessments, and their jobs are thereby dumbed down to just basically carrying drinks around and checking people's seatbelts, then they add pretty much zero to anyone's security, so your argument is nonsense. I'm happy to pay more for competence.
The latter. :)

Displaying his characteristic brilliance and familiarity of Cocoa internals Cédric Luthi submitted a reverse-engineered implementation of the NString equality methods. Fascinating!

Forgive my ignorance, but how do you go about and reverse engineer NSString equality? Looking at the code is interesting but what I'd really like to understand is where it comes from and how it was extracted; is it supposed to be close to the original implementation, is it an informed guess based on CFLite, ...? Please be patient and again forgive my ignorance.

This is some very interesting stuff you want to do there. Try to reach that goal! There's nothing better for an engineer than challenges.

Anyway, even in case you fall short of your goal, learning C can't be wrong. The language provides a very good abstract machine. Probably the best abstract Von-Neumann machine I've seen. Working with it is kind of mind expanding when it comes to understanding computers as well as problem-solving.

A quick suggestion since you said you were taking your first year of CS. Try to implement things you learn, especially algorithms and data structures. It will help you learn the material as well as coding and may give you a couple of insights.
Excellent advice. Also, "try to explain to someone else what you know". That way you'll very quickly find out what you don't know from what you do know.

> Overall sounds amazing, yet for me the thought of no longer needing to buy objects or clothes is a bit disconcerting.

Some observations:

1. You would start buying designs instead of products. You can go shopping for them, just on a meta-level kind of way.

2. You are able to change designs, get designs changed by others (you can get at a shop, maybe), you can share designs with others (social network of things?), you can communicate about these designs, and so on. Stuff can be personalized on a micro and macro scale, whereas now it can only be personalized on a macro scale through combining existing items. With 3D-printing you can personalize the items, too.

3. There will be a growing market for hand made stuff, albeit more exclusive. I think the first couple of decades the distinction between printed clothing and clothing made from fabrics will be clear. That means that traditional clothing will keep its value while printed clothing will be valued less.

If anything, shopping will become a more immersive activity, I think. It'll change from a materialistic activity to a more service-oriented activity.
I'm not sure where this meme that I'm openly flaunting the rules and being rude came from. I just said I make my own choice about whether to follow the rules, not that I act rudely. If politely asked to do something that seems halfway sensible and is not a major inconvenience or problem, by another fellow human being (flight attendant or not), I will of course do the polite thing.
Some tasks contribute directly to goals, other tasks just get you through the day.

Don't know what to make of that, other than to think that those two types of tasks are probably managed differently, and they probably give you different emotional payoff.

The rebuild would be worse than the scrubbing.

A better plan is to light up your disaster recovery plan weekly, and while the DR system is handling the load, scrub to your hearts content on the down system.

Depending on the cost of your hardware vs the cost of your labor vs the cost of downtime, dual servers, one flagged as production and one flagged as development, alternate flags every weekend, might work out. You'll hear lots of bragging about that not being possible because the hardware is too expensive, not so much bragging about labor cost and downtime cost. I worked at financial services corp about two decades ago where downtime was supposedly in excess of $1M/hr. They had triple mainframes set up, basically three machine rooms inside the machine room.
> don't get good deals....you're just lucky to ge the car you want.

If the supply of a certain good is constrained, then obviously the value goes up. Simply being able to purchase one is a good price by definition.
Thanks for this. When I was first getting into programming, people would tell me and others like myself to "go contribute to open source projects". I don't think they realized just how daunting and impossible that seemed to us at the time. To be honest, none of us even knew where to begin.
Jump to conclusions much? Got some passive aggressive issues perhaps?

No one has ever had anything to complain about with respect to my behaviour on planes - not even flight attendants.
That's not how investments work. If someone invests $100,000 in your startup, and you IPO for $10 billion, you don't just pay back $100,000 and call it even. The way I see it, the federal government should own basically half of California.
Riding some other guy's karma, are we?
You're absolutely right, and I didn't say they were all invalidated.

All that the silliness of one rule means is that we have to make our own minds up as to which rules are sensible and which are silly. Which was basically my point.
Of course, that sort of extreme income gradient exists in a lot of cities, and predates any one particular industry -- try walking south from the University of Chicago buildings to 63rd street to see a non-SF example.

A book takes a long time to write. How do authors test the market for a book before sitting down to type?
Nope. You have a very strange view of rules. Who taught you that that's why they exist?

Rules exist because someone (or a group of someones) decided to make them exist. There is no necessity that the rule be actually for the benefit of anyone, though most societies try to require rules to at least seem vaguely beneficial before adopting them.

A month in any corporation should make it obvious that rules and benefits are entirely orthogonal concepts, much of the time.
I'm a 35 year old latin and I have never, ever heard anybody use that word, not on TV, not on books, not on nothing. I had to look it up too see if it was real. Is a weird word, please don't use.

Diesmo, on the other hand is quite common and I guess you can say that diesmar is the act of giving the tenth of your profits to the church. Still, diezmar is a dead word.

Instead we use decimo for tenth and decimar for destroy.
Good point. I suppose "rent to own" would be acceptable though, right? That would be equivalent to an interest-free mortgage.

Vim is too big to learn. Eventually you'll muscle-memory a set of actions, for the way that you uniquely use vim, that you don't even know how to explain without thinking about it.

Rather than trying to go through one end of a tutorial or reference to the other (don't know if that's you), find a site or two of vim tips, and let them randomly trigger your mind. I think it's more interesting than going through anything beyond page/chapter 1 of a reference.

Coupled with that, whatever you find yourself doing in vim, take some time to understand what it is and the alternatives. Becoming familiar with :help's table of contents, rather than the contents of every chapter, is probably helpful here.

Similarly, when you do something accidentally, try to understand what happened. Sometimes you'll discover a feature. q: for example is discovered by accident by many people, including me.

They really don’t care that much about making the world a better place, mostly because they feel like they don’t have to live in it.

It's a disturbing attitude, but it's one that our culture and our public sphere have more-or-less explicitly encouraged.

Nobody is supposed to live in the world as a whole anymore. You're supposed to build a perfect little bubble of your own possessions designed by your own mind to suit your own ego, and live in that. Anyone who cannot or does not do so is deemed a failure.

The problem being, someone has to scrub the toilets, someone has to farm the food, there's only so much beachfront real-estate in the world, and many of us like having a world.

I happen to live on the 7 train, so I know a fair bit about the difficulties of installing it there.

The 7 train is still controlled entirely manually, with the old block-based signalling mechanism that can only be aware of the location of a train in very vague terms. It's currently having CBTC (Communications-Based Train Control)[0] installed, which will give dispatchers much higher resolution information about the location of every train, and go a very long way towards automating the entire system. CBTC installation is scheduled to be completed in 2016, and it's the reason why there are currently so many service disruptions afflicting it during weekends (it actually just began a series of 13 consecutive weekends during which it will not go into Manhattan). If I recall correctly from the posters, the total budget of the project is about $750 million.

If and when the line is fully automated someday, it will become possible to create a reliable barrier mechanism (like what currently exists on the very small automated portions of the NYC subway, which is really just the JFK AirTrain). Until then, human operators can't reliably get the train cars to stop in the same place.

Does Google have to pay the NYT for each link to a NYT page in their search results? I doubt it. That is what the Irish papers are proposing. The NYT has decided that Google traffic is so important, they will let users access their content for free if they come from a Google results page. That to me reinforces the idea that charging people to link to you is self defeating.
The thing about Airtime was so true! I remember their launch being such a big deal! After that, no one gave a crap about them!

> Jump to conclusions much?

When many people make the same assumption you might want to consider whether there's a problem with your post.

Your first post makes you sound like a jerk. Such a jerk that people have down voted you for it; called it disappointing; and called you a jerk.
In addition to randomly generating a man page from /bin, consider mining your command line history and randomly selecting anything whose man page you haven't yet read. You'll want to keep a file of man pages that you've read, to help with that.

And since you're stocking up on C, don't forget that C's standard library is documented via man pages, e.g.

man -k sprintf
asprintf (3) - print to allocated string
sprintf (3) - formatted output conversion
vasprintf (3) - print to allocated string
vsprintf (3) - formatted output conversion
XtAsprintf (3) - memory management functions
There is no coverage of any of these at all. I really think the book is an overview of cross platform javascript issues from 3-4 years ago that someone who wanted to clone jquery would need to know. That is about it. I am really disappointed at the lack of progress throughout the MEAP stage. I hoped it would develop into more advanced areas but it must have been hard for the authors to change focus especially after years of writing the book.
Techmeme's biggest (i.e. tallest) stories of 2012
My favorite raid 5 failure mode is when a old hardware card fails and you have no stock spare and the maint contract was not renewed years ago and the cost of a new card is too much to be expensed and buying as a capital replacement will take a week or two minimum to be approved. And/or the card has been discontinued so you have to buy a used one from a shady foreign surplus dealer. I've seen too much of this type of thing... I can tolerate the (minimal) cost of software raid but I can't survive the possible downtime of hardware raid, so its been software raid for me for pretty much the last decade.

Another fun one was the quad redundant power supply with all four plugs going into the same power strip.

And there was the power supply that blew out every drive in the box simultaneously. I suppose its not any worse than a lightning strike, other than the onsite tech assumed it was a cooling failure, so he replaced the dusty fans and all the drives, thus destroying an entire set of drives upon powerup (and fans, I would guess).

The poison drive tray where every slot you jammed it into, it bent the backplane pins. That turned into a huge expensive disaster.

I am not sure of the power output of a cell tower--500 watts seems unreasonably large. But let's take your numbers and see where the inverse square law brings us.

So multiplying power by the inverse square of the distance in feet for your cell numbers is 0.00133333.

500 watts one mile away gives 1.7935 e-5.

The cell signal is 75 times stronger. And it is inside the airplane, whereas the cell tower is outside the metallic skin of the aircraft, whose attenuation effect we have not calculated.

I suspect the power output of a cell tower is much less than 500 watts. With gain antennas at that frequency and line-of-sight, it is much likely to be less.

Let's take a very popular FM broadcast station: WFMT. Its power is 6000 watts ERP. Its relative strength would be 6.15460 e-7. The cell signal is 2166 times as strong at the cockpit than WFMT.

And that is just one cell signal.
