Some of us do not have the luxury of living in a rv and travelling most of the time, so we take the easy route and go to national parks in the limited time available. I went to yellowstone this independence day weekend, and it was terrific, despite the crowds. It doesn't matter to me that a noname place could have been better, because I had a great time anyway.
The solution seems to be to drive the price of oil up then, no?
I dunno. This seems a little like the "putting a GUI over the CLI" discussion.

> its intellectual core is about formulating things with enough clarity, and in a systematic enough way, that one can tell a computer how to do them.

I think the thing to teach is logic. (Make that Logic with a capital "L.") It covers all the basics: clarity of thought, language and its hidden dangers, definitions, systematic thinking, order, etc. Studying Plato and Aristotle is a great place to start.

It's still possible, and relatively easy, to discover new ruins in the southwest. Especially around Cedar Mesa.
Thanks for the candid reply!

Ha hahaha. Sure enough, I clicked this story b/c I was like, "Oh hey! That matches my interests!" ;)
Thanks for writing this, a blog post is probably a better format than a nested HN comment. I think it would help get this great comment much more visibility.
Okay, I reported it. I couldn't find that link at all when I googled for it. Perhaps I needed to use bing?

Thanks
I guess the conclusion is that because the history was rewritten to mean this content was mostly unpopulated, ready to receive the settlers, with some pockets of Indian tribes here and there.

Anything that contradicts it is difficult to accept.

Also most people don't know, and most importantly they don't want to know. The later is most important. I think even if told, or specifically taught in school, people will try to forget it quickly. It is uncomfortable to think of this country as great and glorious and then put the killing of all the Indians and slavery next to that. It just doesn't fit.

Even on a more superficial level, people don't care because they don't feel it is part of their ancestry.

It is a bit strange to me (but it is just me being weird) that a lot of Americans talk about themselves as Irish, Italian, or German. So I ask usually "so your parents are from Ireland?". And they'd say something like "Oh, no they came in 1850". Yet they have a kilt and go to "Irish" festivals. Nothing wrong with that, but I think it explains why on vacation they want to go to Europe to visit "history" and not to Cahokia.
I just was up there last week and had the same impression, at Prairie Creek Redwoods State Park & the Redwood National Park. Fern Canyon and the Cathedral Trees trail were both amazing and pretty unpopulated - I would recommend it for anyone interested in hiking, who could handle a long day's drive from San Francisco.
It's not a self-contained environment. They didn't have to grow food or recycle air. That was Biosphere II, which was a huge flop.

FWIW, language interoperability is of interest to Sandstorm since apps can be written in many languages. But we're only 7 people with a lot on our plate, so unfortunately we can't currently be the ones to go around implementing Cap'n Proto in every language. That will change as Sandstorm grows.
Worked with this kind of tech for a few years... And trash it to go with Aspose components.

It's slow, and really hard to debug when it's not working (not only pdf output but merge fields).
Why any concern about private land being flooded? Landowners who are worries about it can sell it now, before anyone else has cottoned on or if they want to take a risk, they can keep it. It's an individual decision for each land owner, and they're the ones who'll suffer the effects of their own personal choice. Doesn't seem like something for anyone to really worry about.
It was difficult getting past the words Windows Meta File, the cause of one of my many software headaches in graduate school. I never found a way to export vector graphics from Matlab (admittedly not a Microsoft product) in a way that they could be embedded in LibreOffice (or any other open Office clone) to produce PowerPoint-compatible documents. But I certainly tried.

If the requirements were just to produce a document I could have generated PDFs, but my department head wanted PPT slides. Apparently there is no other vector graphics option that is compatible with both Matlab and Office, and there are zero useful tools for editing WMF files, save for the pathetic options available as part of the Office suite.
It's the same reasons that some products take off and others don't. The right people went and made a big deal out of them early and they were the social proof needed to get more, which begat more resources and infrastructure etc...
The more interesting question is how to become a successful CEO. One thing I have noticed is that good CEOs can frame important problems in a way that allow other people (ideally good ones that the CEO hired) to solve them.
One particular reason is that historic sites that contain Mississippian culture mounds aren't that interesting - they are very hard to interpret, and there isn't much known about the underlying civilization.

I visit many of these sites when I can (for instance, Hopewell Culture National Historic Park, Emerald Mound, and Poverty Point), and there just isn't really much to really bring in tourists. There's absolutely no comparison to something like Tikal in Guatemala. I wouldn't recommend them to any casual tourists. The only reason I went to these sites is that I'm in the process of visiting all of the national park system units in the United States.

The Anasazi ruins in the Southwest are much easier to understand - Mesa Verde and Canyon de Chelly have extremely striking settings, and the lack of vegetation means that the underlying structure is easy to see. When I visited Hovenweep, I found a pottery shard that rodents had dug up, and when I visited Mesa Verde, rodents had brought an ancient corn cob to the surface - so it's a lot more fun to visit these sites.

Also, Mesa Verde is pretty close to Durango, CO, and is on the "Grand Circle" tour of southwest US national parks, forests, and monuments. So it's going to get a lot more tourists than something like Chaco Canyon which is way off the beaten path, and doesn't have much infrastructure.

I have always felt this way. If everyone driving looked at the bigger picture, it would be a much more efficient and pleasant place. Road rage, traffic jams, death, all these things are mostly the result of human error and poor mental judgement.
i keep a spare iphone just to test iOS exclusive apps. I can't stand iOS. it's god awful. maybe I'm just a nerd but I find android to be so much better. doesn't feel restrictive.

I do get upset at google though -- i wish they did more to make it easier for developers to port their apps to android. also the iOS version of apps are built better, it sucks to have a garbage version of snapchat on android. but the sacrifice is worth it to have the physical back button.
Protocap maybe?

Btw, you rank in the 5th result for "protocap" on Google.

Where did you find this policy for $20?

>There's like a weird need for there to be a gate with a ranger taking entrance fees and such, for someone in the US to want to see and experience a place.

Or is the exact opposite true?

Perhaps the United States Government does a poor job of promoting their most breathtaking parks, and only creates parking lots and ticket takers once there is the financial incentive to do so (because the general public decides they want to amass there for any particular reason)?
That's an absolutely terrible idea if you want any kind of forward / backward compatibility. Just about any system is better than dumping structs over the network, once you're dealing with a system that can evolve.

There are ancient ruins anywhere but the volume around Europe is just immense. I grew up in a random Eastern European town and there was a 2k year old roman arch on one of the downtown blocks attached to modern office buildings/residences that nobody even bats an eye at.
The thing that sticks with me beyond anything else was that there was so much horror that day, it couldn't be kept off TV. I grew up with the understanding that you simply don't see death live on TV.
I was wondering if for a REST api, it might be a good idea to provide a htsql endpoint beside regular REST endpoints. E.g. a /htsql/<htsql_expression>; what do people think?
Few in the US seem to know this, but all ATMs in China have been recording currency serial numbers for several years now. It's an option on US ATMs and currency counting machines.

I’ve noticed an interesting trend. Pick any field X, from archeology to zoology. There either is now a “computational X” or there soon will be. And it’s widely viewed as the future of the field.

I was dubious about this particular example and searched for [computational zoology]. There's nothing really there, except for a Craig Thompson making a similar "X could be Zoology in Computational X" claim. Computational Zoology is certainly not viewed as the future of zoology.

https://www.google.com/search?q="computational+zoology"

Why make this precise claim without checking if it's true? Just an odd way to write an essay.

Overall this essay reads like a long, long, long laundry list of features of the Wolfram Language and the Many Wolfram-Branded Products With Many Features, rather than an explanation of "how to teach computational thinking". It's like I wrote an essay "How to use Google for Education", found a thousand educational pages on the internet, and wrote a story in which I googled each one.

Ask HN: Why do all editors have line numbers disabled by default?
Is there a compelling advantage to having line numbers disabled ? There must be, because nearly every IDE and programming based text-editor disables them by default. Even a recent upgrade to Android Studio undid my make-line-numbers-visible setting.

Are there any developers that disable them if they are enabled ? And if so, how does your co-worker quickly communicate the location your bug during a pairing session ?
> Isn't it true that even today, there is no viable competitor to MS Office even on non-Windows OS

I'm not sure what you mean by a viable competitor but LibreOffice works very well for my needs and it runs on Windows, OSX and Linux. It also does a sufficient job of reading and writing MS file formats. For that matter, Google Docs is a pretty good competitor as well.

I think a lot of people have come to accept MS dominance as a given and then put their heads in the sand. It's quite easy to get along just fine in business these days without Microsoft or Apple for that matter.
Not really. The text-mode shell presents you with a hierarchical file system where "files" are organised in a tree of "directories" and can be opened in various programs --- and so does your typical GUI. The only new thing added by the GUI are interaction and composition paradigms; e.g. windows, letting you simultaneously operate several programs (directly), and the clipboard replacing pipes. The features mentioned in my previous post are mostly implementation details and could just as well be moved to userspace; they hardly demonstrate some inherent "directness" of the command line.
They also alternate between male/female and hermaphroditic phases.
Well, there's also that there isn't much history to talk about with Cahokia, since not even the Indians knew what it was for by the time North America was colonized. I don't think people would care much about Stonehenge if it was just a round dirt mound, no matter how old it is, since we know so little about the people who built that one, too.

A big part of the appeal of historic sites is the connection with a familiar narrative. There are stories written on the walls of chichen itza, or tikal. We know almost nothing about the people that built the mounds in St. Louis.

No narrative, and not particularly visually appealing, and you're not going to have much of a tourist site.

I use Java RMI to connect AIX to W2K3 running a service that uses Jacob COM to call Excel. It reads a CSV file off a Samba share on the AIX box and saves back an XLS.

The lock file is on the AIX side because Win files aren't atomic.

It's a bit Rube Goldberg-ish and has low traffic, but it's rock solid.
> Looks like you haven't worked on embedded systems.

I've deleted a defensive technical response to point out that these dismissive assumptions (usually unjustified) are pretty prevalent on HN, and I don't think it promotes level-headed discussion. It reads like "Let me discredit a stranger's background that I don't know, and then argue my opposing view." It creates a defensive mindset off the bat.

Edit: I mean, your points are valid. We won't agree on them, but I don't like the assumption that we won't agree because I'm ignorant to them.
While I just berated American tourists for taking the path of least resistance and mostly sticking to the "big" National Parks, there is some value in sorting out the "must-see" from the "also amazing, but not as much amazing stuff to see in one location". If you can only stay in the US for a few weeks, hitting the high points may make sense. I've been traveling for years, and still haven't seen all of them, though I'm trying.

If human ruins are a priority for you, then the ones I've mentioned are maybe the best starting points (though Casa Grande Ruins is "only" a National Monument, and not a National Park; it's maybe a place to visit for a day or two on your way to or from somewhere else, unless you have a specific interest in the Hohokam civilization or that era). Mesa Verde is astonishing in its history; it was inhabited, off and on, for thousands of years, with evidence of habitation as far back as 7500BCE, and multiple eras of civilization represented. That'd be a good one to visit if you want to learn about ancient civilizations in the Americas.

Frankly, I think one could make an amazing vacation by visiting almost any National Park: https://en.wikipedia.org/wiki/List_of_national_parks_of_the_...

I like to spend a week or two or three camped in the park, depending on the size of the park, and what kinds of exploration one can do. Some are bigger than others. Denali could take weeks to explore pretty thoroughly, Yosemite is maybe more of a long weekend.

Note that for most of those, the archaeology/anthropology angle is minimal, though almost always present; it's usually the terrain itself that is the star of the show. Most of our National Parks will have good materials about who lived in the area and when (and it's often fascinating and a good way to spend a day or two of your visit, and there's likely to be tours that focus on that aspect of the park), but the geological/natural features are often the focus.

Our National Parks system is among the things I'm most proud of about my country (and I have lots of things to be critical of). I wish I could show it to everyone in the world; but, most Americans haven't even visited more than one or two, so I guess we should start there.
Also as a note, both ciphers suggested are stream ciphers, so you will need some way of authenticating. Depending on your needs, you may consider using something like libsodium that takes care of all of that for you:

That and what I take to be the iCloud / System Indexing daemon's (like `mdfind`) kill my battery life. The other's reports of poor Dropbox performance baffles me a bit as it never seems to give me issues, but iCloud/Google Drive both have both had big performance penalties on 3 various macs I've tried them on.
I doubt it will become a problem in my lifetime. America is big. We have a lot of beautiful mostly deserted places, including a lot of federally protected land. I'd like it if more people got out into it more often; there might be a bit more concern for protecting it, if more people saw it in person.

Schemas are IMO the only way to go when you are transferring between heterogenous languages, even when all languages involved are untyped.

Consider javascript talking to common lisp. Of course JSON has a canonical mapping to javascript, but it does not for common lisp. Should a JS array be a lisp list or vector? Should lisp's NIL be false or null? Should a JS object decode to an alist, plist, or hash-table? &ct.

I read that as "not too demeaning for a typical dev".

As a fat guy, exercise is demeaning. My bicycle broke today. I looked in the manual, and it has a weight limit of 200 lbs. I'm 60 over that, and often carry ~15 lbs in a backpack. :(

"demeaning" is definitely the word.

That's great, and I don't mean to sound demeaning of that kind of decision-making. I understand my lifestyle provides a tremendous amount of privilege in this area.

I just think of the times when I've had conversations with folks who live within an easy day trip of some amazing place, and I'll say, "I'm stocking up to camp at X place for the next week or two." And, they'll say, "Oh, yeah? I've heard of it. Never been." It's surprising. National Parks at least tend to have been visited by the folks who live nearby, often regularly.
Great news, and thanks for the response! I don't have an immediate need for a system like this, so perhaps by the time I do there will be broader adoption.

An anecdote related to ruins. I made a pit-stop at the Timbisha-Shoshone tribe's reservation when visiting Death valley. They clearly had a long-running feud with the federal government about land (often mentioning that they felt like cattle when someone erected a fence around them).

I asked them where I could see some historic Indian artifacts in the area - paintings, burial grounds and the like and they were pretty offended that I had the gall to enquire such stuff.

I guess for most native Americans not enough time has passed for the wounds to heal and there is a sense of humiliation when folks show up expecting a good photo op as if they are some extinct civilization.
Recently I've started compiling more of my code for Windows using Mingw (or clang). Performance is very good and you can build in Linux for Windows inside a Docker container. You can even build Windows installers using NSIS. I've also tried to do this for OSX but with less success.
I lived in Pittsburgh from 1989 to 1991, very close to Carnegie Mellon University. One of their technical departments (CMU) had a self-driving car (really a van like a UPS van) even back then ; we saw it driving around our neighborhood sometimes. I think it always had an operator standing by inside it, for override.
At some point you have to make an ethical decision -- what is the best allocation of society's resources? It would be expensive to outfit all tall buildings with parachutes in the exceedingly unlikely event that they would be useful -- and that's before you factor in the low probability that they would successfully save people with little to no training in normal parachuting, much less BASE jumping, a sport which often kills trained participants jumping under far more favorable conditions.

You might as well ask why people who work in tall buildings don't take parachutes to work themselves. The answer is obvious, and I hope it's equally obvious why buildings don't do this.

On a related note: having to send your shoes through the x-ray machine in an airport security line is almost as bad of an idea. :/

I'm liking the idea of take-home and cooperative tests more and more as I progress through teaching experiences. I believe the tests should be an instructional experience, too.
