Fair question. I don't travel a lot. I live 1.5 miles from the centre of a city of a million in the UK. We have been staying for a week at a time at various seasons just outside a small town (2,500 population) in a national park a few hundred miles away for the last two and a half decades. Green fields outside the door and a river with (last week) a couple of herons hunting.

So I travel for contrast and to the same locus for continuity and to observe changes. The sudden appearance of disinfectant mats at the start of the foot and mouth epidemic, the slow turnover of farm transport from green Land Rovers to quad-bikes, a new generation taking over some of the older houses (micro-breweries and food pubs). The rise of serious bicycle riding as a local sport.
Thanks for those links, really interesting. Summary for anyone who hasn't read them: Diaconis did detailed analysis and ran experiments and found that coins are biased to land the way they start, but it's a small bias in normal use (51%). The article also claims that he has trained himself to reliably flip coins so they land the same every time.

Interesting that it seems to contradict the article linked here.
I've been a user on the site for a few months now. There's a lot you can imagine would be difficult with threaded chat, but in practice it works pretty well, to the point that I generally miss having the ability to reply to a specific message on other chat platforms.

When winter biking in Pittsburgh, I found the road "salt" rapidly corroded everything it touched on the bike, except my aluminum frame. Perhaps the road salt screwed up your freewheel moreso than the cold.
I don't know what is better about traveling (specifically the leisurely kind) - is it that there is some kind of comfort in escaping your daily life or is it the new experiences you find in a new place with new people?

I know someone who goes from Singapore to Germany every year for pleasure. He has done it for the past 8 years. It's his "favorite" destination. I guess for someone like him absolute "newness" is less important but "escape" is more important.

For others who live by the count of number of cities/countries/continents they have "covered" traveling seems to be a mission in itself. They travel for "newness".

I would say that a common answer to the "why" might be that we all like to escape our lives at some point or the other. Traveling provides that along with entertainment.
I've been at the 100k-mile tier with US Airways (and now American Airlines, courtesy of the merger) the past two years in a row. Thankfully, this year I'm dropping down below that; I'll probably clock in around 60-70 thousand miles flown in 2015, depending on how much I do in the final quarter of the year.

On one hand, it's much more relaxing to not be constantly away from home and shuffling between hotels and airports. On the other hand, I'm going to miss the perks; might have to switch over to Delta for next year, since AA only provides free upgrades at the very top tier.

Most people don't travel because they can't. Traveling is a type of large-scale consumption that re-affirms self-worth through wealth display.
Yes, references are to "refer back to" - the key part here is that what are they meant to "refer back to"? A set of formulae, symbol manipulation or how to apply functions? References should be notes that help you recollect what you'd learn. In this case, the references recollect a set of manipulation of symbols which happen to be Linear Algebra.

Do note that I am talking about "Reference Manuals" in general and not this particular CS 229 manual.

The ecological impact is a very important question actually that doesn't get as much attention as it deserves. Is there any way to travel currently while minimizing ecological impact?

Speaking as someone more than a decade older than the average college graduate: I like to travel to see and experience things. Until this year I'd never been snorkeling (did that in Hawaii), and I'd never been to an opera in New York (did that on Valentine's Day).

Also, given that I work primarily from home, it's nice to take a break and not be where I work.
This space is just bizarre in general. The fact that a smoke alarm was Nest's #2 product was strange given the advantages over standard ones are marginal. Then they did a poor job executing (remember accidental wave off...). In the same space, all these VCs pumped butt loads into this mysterious company, Leo, who was making an audio/internet bridge for smoke alarms (I am sure they had more eventual value planned but that was the pitch to the consumer). I think they laid off over half the team when reality set in.
Panniers are very luxurious for the reason you cited. Where they fail me is when trying to combine a bicycle leg with one by bus or subway - the backpack wins in these cases because I don't need to remove/re-attach my Ortlieb pannier (which gets to be really annoying even despite Ortlieb's really nice quick release mechanism on their urban models).
Probably same reasons that keep them poor like being too busy with the day to day effort to stay afloat.
I can never read travel writing. It just puts me into this manic state where I glaze out and start thinking about getting back on the road. If I'm going to find out about a place, the only way to do so is to go there.

So if you're asking why folks like me travel (75 countries, 3 laps around the world, maybe 5 years total abroad and moving over the 10 years before I simply moved overseas for good), the answer is that I've never even considered the question before.

Ask an alcoholic why he likes alcohol. Ask your little cousin why he likes his phone. It's the thing you arrange your life so that you can do. It's that important. If you have to ask why, that's just a sign that it's not for you.

And that's fine.

That's not entirely true. Travel can be done on the cheap, many people don't even explore their own city. People who don't travel find a million excuses, but it usually boils down to fear of the unknown.

So, let me get this straight:

* One unit sounds a false alarm (because normal smoke detectors never ever do that)

* The rest of them relay the alarm

* He then takes a sledgehammer to the unit that generated the false alarm

* ..And because of this, he has "no trust" in the nest protect.

And this guy writes for Phoronix?!

Yknow, downvote me if you wish, but that post just comes off as remarkably ignorant, with a side of "all that newfangled tech these days..." ludditism subtext. And the fact that he took a goddamned sledgehammer to the smoke detector is just the icing on the cake. It was stupid behavior, as is the suggestion that we take that post seriously.

Devices fail. Find a person, any person, and they'll tell you that they won't use X brand of thing because they had one unit of said thing fail on them one time. This is that fallacy, writ large, but less forgivable because this person writes for a tech blog of some note.
We have this wonderful world around us and I'm willing to bet that most people have not seen more than their hometown, its surroundings and maybe a few holiday spots. A large number do not have the means to travel, but if you exclude those a better question would be why not to travel? Even for the things you mentioned, why not do them at a place you have never been before? Are you not curious about the world? Do you not like to try new things?

I keep seeing this attitude any time travel comes up on HN and I still have no idea where it comes from. The idea that travel is nothing more than banal consumption for the purpose of puffing up your Instagram account is absurd on the face of it.
Yeah, the difference with the disk full alert and the alarm is that the alarm is emitting a very obnoxious noise continuously while you're trying to debug it; and in the meantime, not actually providing a useful service, like the server is. Trying to debug a problem at 3 AM when you just want to go back to sleep because there isn't anything actually wrong, just faulty alarm hardware, is not nearly so useful as clearing out some space on a full disk when it is in active operation.
The symbols themselves are not encrypted, so you can still list those without cracking the app.

The Hollywood Gender Age Gap
I didn't take the end as "just a collection of destinations", but rather a selection of vignettes illustrating the various reasons one might travel to a particular destination. There are a multitude of reasons one might travel, and the author's pointing out some good ones, along with a personal reflection on that. The sections on the beach and the pumping station particularly spoke to me; the former because I'd previously seen a beach vacation as an indulgent waste of time (but have since come around), and the latter because, though it seems almost like a platitude, not enough people encourage others to make a trip planned around what they find particularly interesting.

To your latter point, I'd say that a lot of the time people embark on travel for the "wrong" reasons (some of which you mention, like boredom, social pressure, etc.) but end up discovering better reasons along the way (those illustrated in the destinations section). I think there is a stroke of admonishment in the article--asking the reader "why" _they_ travel. Personally, the more I demand myself to travel with purpose (as I have), the less I end up traveling. And my trips have been a lot more fulfilling as a result. But it's a little ironic in that, it's taken a lot of traveling to get to that point.
I disagree, these 'dumb' smoke detectors are spot on.

Learning to cook, ceiling height regulations and hallucinating aren't problems a smoke detector is trying to solve.

Also, if it beeps when there is smoke (from your cooking), it is doing it's intended job.

Fires from cooking (2013) take up nearly 50%!! of residential building fires.

I've heard from prior owners that the depicted experience is authentic and very typical.
> Due to their nature smoke alarms have to fail in the most annoying way possible, and be difficult to disable.

Why? Why not make them so that you can easily press a button and disable them for X amount of time universally? The one in my apartment has no silencing mechanism and trips every single time I am cooking on high heat. I literally have to rip it off the wall to get it to stop, and the result is that I now cover it while I cook which is probably the most likely time an actual fire will develop. Yes we really don't want false negatives, but if something designed to protect against a statistically unlikely event throws inordinate amounts of false positives with no recourse for silencing, people will just disable it.

I agree that savings and restraint in spending are not the main issue. But on the other hand, if you:

1) Graduate high school,

2) Wait until age 21 to get married, and wait until marriage to have children; and

3) Have a full time job (any full time job),

then you have a 2% chance of living in poverty, and a 75% chance to be middle class. So in order to argue that bad choices don't matter, you need to make the case that one of these three steps is impossible for most people who are poor. I think your best bet is #3.

I wonder what Nest Protect is using to detect smoke that it false alarms, in a pot with a lid on it, without any smoke anywhere in the vicinity.

Unsmart smoke detectors use minute amounts of radioactive materials (such as Americium-241[1]) and almost never false, although they can be annoying if the source of smoke is otherwise legitimate.

My chemistry professor in college pointed out that a big stack of smoke detectors in a hardware store was not regulated and yet would collectively emit radiation that would probably exceed legal limits for people walking by. I thought about that the last time I was in Home Depot and there was a huge stack of $10 smoke detectors. (Yep. I bought three.)

Re-read my question, I think you're slightly misunderstanding my point. To quote my original post, "I traveled a fair share too and generally enjoyed & learned from it, but so do I when I simply spend holidays staying in my hometown reading, socializing/partying with friends, spending time with loved ones, coding, gaming, and resting."

I'm not excluding the occasional travel and am very much enjoying it and trying new things. What I am questioning is the extreme prevalence of travel in off-time for some people for whom travel seems to be the only way to spend holidays.

More poetically (but probably a bit patronizing, thus my original post which instead asks questions): traveling is cool, and staying at home is fine too. Next time you're planning holidays, what if you gave yourself the chance to appreciate your surroundings in a way you're not necessarily doing while in your regular job routine? You don't have to board a plane to see new things. Chill out. Meditate or try to build something if that's your kick. Go have a walk around the neighborhood. Take your time.

Considering that I just picked up a 24 unit LTO5 stacker and a box of tapes for ~750, you may wish to decrement that 100% by a few points :)

The problem with live redundancy is just that, it's live. If your backups are live and online, they are not backups. (For the same reason that RAID is not backup, it's redundancy).

Think less "deployed broken code to prod" and more "this special snowflake server crashed" or "the datacenter caught on fire".

Disaster recovery.

The use case for tape is the same as the use case for something like Amazon Glacier. Perhaps you don't want multiple terabytes of your personal data being sent over the wire to a company who's no doubt been infiltrated by TLA's. Perhaps you want total control of your own data. Perhaps you don't want nasty surprises when it comes to Glacier's retrieval/data in/data out/you-didnt-wait-long-enough fees.

A single LTO5 drive can be had for about $300, tapes for $40/$50, and that'll get you around 2TB of storage each, more if your data compresses well.

Let's not pretend that there aren't real benefits to be had, here. Your use case isn't everyone else's use case, and certainly not enough to be making broad sweeping statements that nobody on HN uses it.
Anyone who is worried about privilege escalation on OSX should be aware that Apple ships sudo with requiretty disabled.
