Who is "we?"
I love traveling but I avoid couch-surfing like fire. I think is down to the kind of person you are.

Hostels are my time off. I can sleep in my bed as long as I want, I don't have to talk to anybody, I can pay and not ask/talk. Socializing is huge energy consumer. Hostel time is when I don't have to worry about a thing, relaxing and recharging.
AJAX and REST sure are evil. The fact that 229 people have upvoted this is certainly proof that web-based UIs are something that we as hackers ought to oppose.

We are all aware that PRISM has been exposed to be nothing more than a user interface to information provided by companies that receive a search warrant after the request has gone through courts and lawyers, right? Surely 229 users of Hacker News cannot be that uninformed about PRISM, after so many front-page articles on the subject giving so many opportunities to hash out the details of what it is and is not, that they imagine it to be something nefarious?

Ask HN: Hackathon - 2 minute pitch. Resources for pitching?
Long story short, entering a programming competition at my bank. 50 teams, 150 students total. We have 24 hours for the prototype development (already done), and then we have a 2 minute pitch in front of a board of executives.

We have a great idea. An idea that benefits the consumer, small business retailers, and the bank. Location based promotion application. You can filter products from small business by sector (electronics, housewares, furniture etc). Once you have selected which promotions you want, these promotions are mapped out using the Google Maps API. When you are near one, you are sent a push notification with that promotion.

Bank benefit:
- establishes relations with small businesses
- consumers spend money on VISA which incurs fees and payments, more money for the bank

Retailer benefits:
- more customers / visibility / publicity

Consumer benefits:
- save money
- earn redeemable points for products by using these offers
- discover local businesses

We have 2 minutes to make a pitch to the board of executives and CEO of the bank.

What resources do you have that can help me HN?

Getting a job teaching English can provide a work visa. Easier to do in some places than others, though.

There's also a middle ground I might consider ideal: choose 4 places to go to, and spend 3 months in each. You can't pick up everything a city has to offer in 3 months (let alone a country!), but it gets you much further than the 3 days here, 4 days there strategy. Cuts down on travel and housing costs, too, both monetarily and temporally.

If you want more extended trips than that, you can often go on a day-to-weeklong vacation to a neighboring country and return to where you were before, bringing it to a 6 month stay in a city. I'd almost argue that if you want to be there longer than that, you actually should pick up a local job, not just to fund yourself (which is probably a minor point for most of us) but because it deepens your experience in a place.

If you're pretty well-off, at least some countries will offer you an "investment visa" if you can prove you have hundreds of thousands of dollars in liquid assets.

The cost option is how algorithmically complex the resulting hash will be. The greater the cost, the longer it takes to create the final hash, but the more secure it is. Lower cost = lower secure.

Basically you want to use as high of a cost as you can on your servers hardware, without producing a noticeable slowdown to the end user.
I imagine they must start out doing it like this until they test usage, etc.. Who knows how people could take advantage of it otherwise. It would prevent a possible initial problem of a ton of battery packs just building up in one location. They'd want the first users to to be regular users, and by keeping it to those who it works for, the service will be available faster + once again they won't need to build capacity to store a huge excess amount of of battery packs on location.

I also have to wonder whether such high-achieving and renowned people, being quite busy and in-demand, would of course decline an interview with someone who couldn't further boost their status or spread their message and would otherwise just compete for scarce time.

I am noting that even the author of this article did not identify the anonymous hungarian professor.

Only if taking the same amounts, which is ludicrous.

Alcohol is plenty dangerous already and we're all ok with that.
I don't doubt they have all of those issues covered, but was looking at some of the damage reports from Hurricane Sandy on the subway in Manhattan and thought "hmm if a surge of saltwater submerged one of these things you would only have a limited time to get it un-submerged before the saltwater got into the packs. When that happened you'd be in a world of hurt.

It sounds like cultural and historical context is important to you. It may not be for another traveler.

Traveling is about living in the moment and doing whatever makes you happy :)
What outrageous actions? What outrageous policies? What long-festering problem? You haven't said a damn thing, just as Snowden has yet to expose any wrongdoing on the part of the NSA. He has said that the NSA is spying on everybody, but all of the evidence he has presented has shown nothing of the kind and in fact shows that procedures to protect our privacy and 4th amendment rights are in place and being followed.
In this case it was used as a treatment for opium addiction, right? A doctor prescribing a given drug will specify a suitable amount to get the desired effect. One drug might be more dangerous than another e.g. because it has a more narrow therapeutic index, but surely not because it has a bigger effect for a given mass of drug, or because it is "commonly encountered" in big doses?

I agree that polarizing comments may detract from a discussion, but I also believe they may serve a useful purpose, which is to more clearly define general sides of an argument, which can then be easily used to individuals to define their particular stance. E.g. I believe/am an X, but with caveats Y.
The fact that I have time to type this seems to disqualify me from commenting.

Not a neuroscientist, but used to work in the field, and my first idea was "well by cutting it up, they also cut all connections". And those connections are far more important for understanding how the brain works than seeing where an individual neuron is physically located. Unless off course they can somehow get the connections out of it.
I think wireless charging built into parking spots or even long stretches of highways (charging while driving) would be a lot cooler.
I spent 2 years driving a little Jeep Wrangler from Alaska to Argentina, because I wanted to.[1] I'm a Software Engineer, and did some freelance stuff while on the road.

For the entire 22 month, 65,000km (40k miles) journey through 16 countries, I spent $27,300 [2]. That's only $1200 a month, which is barely more than I was spending to live in a city and go to work every day.

I'm extremely happy to answer any questions or help anyone that has an interest in traveling like this. WikiOverland [3] has tons of the logistical information you'll find helpful.

I'm running one of these on my free EC2 account and can attest to the ridiculously easy part. It took me < 5 min to setup. If you want to avoid paying any fees, just have to make 1 change to the torrc file bandwidth settings. Also, make a great ubuntu sandbox to play with. For example, I'm running a joomla test server with it.

From what I understand the list is part of the ChromeBot Tool, a sub-project of Chromium.

ChromeBot is a distributed crash detection system.

Chrome is run on a list of URLs to check for crashes. A
pool of machines is used to distribute the workload,
each machine might potentially launch several instances
of Chrome. Crashes detected are symbolicated and saved
in database.

HK blames factories in Southern China. Even if both claims are true with respect to total pollution, both regions could be doing much more to reduce pollution

This is a common misconception. The reality is that local sources cause the majority of Hong Kong's air pollution. Marine, road transport, and power generation are the three primary contributors.

Marine contributes an astonishing amount of SO2 and NO2 and the worst part is that is easily solvable. While most developed countries wont allow ships to burn filty bunker fuel within ~100 miles of the coastline, HK allows them to burn it for days while sitting at port. There was an article a few years back about how the largest container ships each produce an equivalent amount of air pollution as 50 million cars when burning such fuel.

Several logistics companies voluntarily switched to cleaner fuel on a trial basis. The cost difference puts them at a disadvantage to their competitors and they have urged the government to force the requirement on all. Without it being mandated, they will be switching back shortly. Predictably, the the government has refused citing a "need to coordinate with neighboring regions". No doubt they will put a committee together to study the potential to create a preliminary discussion document due 2033.

Dangerous? Alcohol has much more systemic toxicity than GHB in general. Consider if you consumed 3.5 grams of tylenol. You will die. Does that make it more "powerful" or "dangerous" than alcohol?

That is the point we are trying to make.
Nice summary, but this looks like a writeup of somebody doing this the first time. There's lots of room for improvement.

First off, there's way too much planning going on beforehand. Having done several of these trips, my pre-planning now involves booking a single flight and letting things work themselves out from there. Dates on the calendar are really really bad to have, since they force you to move faster or slower than you want to. Avoid them at all costs.

And, of course, he overpacked. 90 liters is way too big. 40 liters is probably still too big, but at least realistic. You want to be able to fit your full pack on your lap on a crowded chicken bus without drawing angry looks from the locals. One complete change of clothes is plenty. Most of the stuff you think you need, you don't.

Beyond that, there's a lot of good stuff here. Sounds like he had a fun trip.

Carmack's famous games were not developed solo - he developed the breakthrough enabling technology that made the game possible - full-screen sidescrolling on a PC, 3D stuff, etc.

Mechner's games stand out in part because he seems to have done just about everything himself and, especially for the time all the parts are outstanding - the design, the artwork, the 'art direction', the animation, the gameplay. And then he went off and churned them out in 6502 assembly.
They are already effecting change; seeing this on the front page has made me have much less respect for the Hacker News community. How can so many people be so stupid, and on HN of all places?

Clever marketing. I've seen Vine videos explode as examples for things in the last few weeks, along with news and blog Vine embeds. Interactive marketing is going to get a lot more interesting with Vine clips (until of course we get saturated with those marketing messages and don't find them as unique anymore).
I suppose a simple way, without getting involved politically, would be to stop using any service which is hosted in the US or by a company that falls under US jurisdiction.

A stampede of users leaving the likes of Google, Facebook, etc. would put pressure on those companies to use their resources to fight it 'at home'.

I realise this is a relatively naïve POV, but you only have to see how quickly Instagram reversed their ToCs a few months back - after users started closing their accounts in droves - to see how this can prompt the big boys into action.

You could also argue that there's a real opportunity for a European competitor to launch a rival to these services, under the guise of our strong data protection laws (in the UK at least). So if a DropBox or Gmail clone (for example) started to get traction, again it would put pressure on.

Yeah, a relative had that with an iPhone 5 charger cable: walked into the store and the tech simply reached onto the shelf and gave him a new one. No waiting, filling out a 3 page form, 6 forms of ID, etc. Completely changed the mood from griping to “Wow, I'll buy from Apple again” – quite a contrast to the rest of the computer industry which is generally chasing Walmart down the short-term cost minimization rabbit hole.

Note the .EU domain name and the non-US/Europe focus of the content. As far as I've seen reported or stated by US representatives there's no going "through courts and lawyers" for non-citizens. PRISM may very well not have changed any of that but it was at least a wake up call outside the US for the fact that using US-based companies puts decisions about your data privacy in the hands of governments that view you, as a foreigner, as having absolutely no rights.

This is particularly scary because people have so far been used to considering the Internet as a sort of borderless global place and when it comes to privacy from government snooping it definitely is not.
There are a lot of different cultures in the U.S., but I think the biggest differences aren't the regional ones, and imo hard to get a feel for just by traveling. The lives and cultures of people living in rural areas vs. urban areas, wealthy vs. poor areas, nearly-100%-white vs. nearly-100%-black areas, etc., etc. are all very different, but they aren't primarily state-to-state variations. For example, I found living in Houston and Chicago to be not that different: I lived in a middle-class suburban area in both, and their culture was more "middle-class suburban American" culture than any kind of distinctively Midwestern or Texan culture. I think there's some of that in cities, too: SF and Portland and parts of Manhattan have more in common with each other than with some places that are geographically much closer to them.

Living in a different one of those cultures can be very educational, but it's somewhat hard to break into unless you have some organic reason to be there or social connection. People are often resentful of "lifestyle tourism", the stereotypical one being an upper-middle-class white kid who moves to a poor minority neighborhood as a cultural experience. Small rural communities can also be quite closed as well, in terms of being able to really join the culture (vs. just visit the town).

The article states: Singaporeans are also baffled as to why Indonesia has not yet ratified a regional agreement on trans-boundary haze pollution. Mr Laksono could provide no clear answer.

I think Singaporeans are smarter than that. Unless this agreement comes with huge payments to Indonesia to help them change agricultural practises what incentive do they have to sign it? They are the biggest polluter and my understanding is that the agreement mostly comes with "help" for Indonesia in areas of each other signatory's choosing - also known as "nothing."
Without knowing your nationality its hard to advise.

I'm British, so maybe its easier. You can get a 3 month tourist visa, with a 3 month pending extension from the London embassy.

Failing that you can do a 'border run'. I quite like being near Chiang Mai or Pai. From there its about a 3/4 hour drive up to Burhma. I did it with a mate of mine for a day out.
> If you were just now appalled to learn about the changes made to FISA with the PATRIOT act, you are 12 years behind the times.

This is the #1 counter-comment to PRISM posts that I see, and I don't understand it. "Your opinion is invalid because I knew this all years ago"?

> There is no practical difference between the U.S. companies listed on the PRISM slides and U.S. companies that are not; FISA covers them all.

Which is exactly why the focus on the website is on Europe.
I'm if the 15 second timer on instagram will be more popular for product demos than Vine's 6. It's probably irrelevant (since Vine could just change the timer to compete), but may have an interesting temporary influence on adoption.
Governments plural. The naive part of this campaign is the assumption that the US is the only government doing this, rather than the one with the leakiest operation.

Asking EU governments to censure the US when they have their own programs (the UK clearly does) is just naked anti-Americanism.
