I've never given much thought to what the airlines might claim to be the breakdown of the sum I pay for the flight because the fixed costs don't really define the lump sum price anyway.

Competition is fierce enough to drive down those costs over which airlines have any control at all. I think that for any route worth its salt the prices are close enough to what's actually sustainable for the airline and not necessarily that much higher. This is very different for more remote and less-used routes where one or two company might enjoy a geographical monopoly.

The thing is that the airlines make sure there's always something you can buy from at a crazy prize. The classic example might be the first class ticket for the next departing flight. Even each first class and business seat allows the airline to give a small discount for all economy seats because people are willing to pay a different price for things they value differently. Further, because seats are sold one by one, even economy seats can cost double or half depending on when and how you're buying them.

Personally, I book my flights somewhat in advance, picking a combination of flight times and prices that I find tolerable myself. The limits are all subjective and can change. But I don't care if I paid five dollars/euros/pounds more or less because of "passenger civil aviation security service fee" because the major factor for how much I end up paying is how the market works for airline tickets. If the fee was 2 pounds or 20 pounds, I might still be paying the same price. Or I could be paying a hundred pounds more (or less) for the ticket even if the fees would be a few dozens pounds less (or more).

This is what the place from the first photo in the article used to look like, before it was closed off for cars:

The closures started ~2007 and were gradual. First, traffic was limited to buses and people who lived there, and only a street or two were closed off. Then it slowly got closed to all traffic and expanded to almost the entire old city centre (and it's still expanding). The change was far from universally welcomed intially, but I don't think the mayor is exaggerating when he estimates that today 90% of people would vote to keep it closed. It takes some time, but the feeling of the city changes completely when it becomes pedestrian-focused...

I've been spending a lot of time in NYC lately and was also there 2 weeks ago during the storm and the closure of all roads. I felt like I got a peek into what it would look like if it underwent the same transformation :) If not a full closure of Manhattan to cars, the underground trash containers, at least, they should adopt.

It would be cool if SF tried closing part of Chestnut or Columbus or Union or one of those...
For nearly a decade, I lived in New York and managed to avoid BA for all my travel needs.

I recently moved to Doha and am working remotely for my company, with occasional trips back to the motherships in NY and London. Unless I fly ME3, BA is all that works for me.

Alas.
How about the following: The examiner can provide any picture of their choosing to two subjects A and B, where one is a human and the other a machine. At the end of a reasonable period, both subjects respond to the examiner simultaneously with one drawing each, derived from that same picture. In creating each drawing, A and B are both trying to convince the examiner that they are human. The examiner then should identify which of the two subjects is a computer and which is human. To better reflect the traditional Turing test, the examiner should be able to repeat this process with different pictures (keeping the identities of A and B unknown, but fixed) before making their determination.

Interestingly, this is a Turing test that, when applied purely to humans, doesn't require said humans to share a common language.

While nothing will compare to the 'first time', the bewilderment need not diminish to zero.

Ultima Online was my first and still favorite MMORPG back in the late 1990s/early 2000s but when I tried EverQuest for the first, the 3D world and depth of races/characters/NPCs blew me away.

Then I tried Dark Age of Camelot. The 1-world-but-3-continents/factions concept amazed me. There was always 'the others' and a sense of citizenship with the group of players I could actually interact with. Everyone in UO/EQ was a potential rival/friend. In DAOC I knew where my loyalty lied and the enemy was always clear.

Then I played Ragnarok Online -- my first Korean MMORPG. Again, blown away for totally different reasons. The music, the colors, the sprites, and GIRLS!! Lots of girls played Ragnarok. I didn't meet any girls on UO/EQ/DAOC -- 95% boys, 5% house wives.

Next up was Star Wars Galaxies. No more 'levels', back to skills ala Ultima Online but in a totally different and more complicated way! 3D persistent housing! Crafting! Dancing at the local cantina as a totally legit profession! Multiple PLANETS!! OMG!

Then came World of Warcraft -- nothing I hadn't seen before this time. But it was presented in the most streamlined manner and was the first MAINSTREAM MMORPG. Everyone my age was playing. I felt like the grizzled veteran of the genre/ I knew the mechanics. I taught my friends how to tank. How to heal. How to lead a raid, etc. Again, amazing for totally different reasons.

Sad to say, I haven't felt anything new since WoW. But I honestly don't think its because the genre is played out. Its just we haven't been shown anything different. That might change this year with plenty of promising games in the pipeline -- Shards Online, Albion Online, Camelot Unchained, etc.

If you still think the genre has hope, check out my ~1yr old website, http://mmos.com I hope to see you on my next adventure.

Not a designer but much of my job is styling web content and working with designers and devs. I'm paying for a couple months of "team tree house" which has pretty good videos, little quizzes, and a wysiwyg editor so can you follow along and code.

The videos spell things out nice and slow, sometimes a bit too slow but you can fast forward if you already know a section.

It's meant for web designers, so I'd imagine it would work for your friend. The site also has courses for a few web programming languages and Wordpress etc.

Anyone else used this?

Exactly the same for me. This is how I got interested in programming. The fun part is that many of the people I met on the runescape private server forums 10 years ago I still talk to daily. Complaining about college and our day jobs in IRC. We all have the same history and all sort of ended up in the same place.

Big chance that I still know you as well if I know your old nickname. Especially the programmer community was pretty cozy.

It's quite hard to build up a following these days. In the last 5-6 years, I made such newsletters for the coffee world, airports, plus cultural items and tech news out of Brazil. For all of them, I made use of my knowledge/familiarity of Romance languages and would thus translate foreign news to add to my newsletters. Essentially, I learned they were "nice-to-have" but not necessary in order to operate in these fields (the latter being what I was aiming for).

- For coffee, I learned people in the know are after 24/7 changes in the commodities market.

- For worldwide airport news, well, I don't think there is much of a market there (though I would regularly capture 30-50 pertinent articles per day).

- For Brazil news, cultural awareness is nice to have but in order for something like that to be needed, I would think the focus would have to be Business, and very specific (in fact, I played around with making newsletters like this).

- For Brazil tech, I think it was too early on in its development because there were only around 10-15 items per day.

There's a final component I failed to consider with the first two newsletters above, I had no product dev, no one on the inside to say "hey, focus on this aspect, that's what people need."

General complaints about PayPal are landing all over this thread, and Dwolla answers many quite nicely; you're welcome.

As for the article, I would say: a pox on both houses. I endorse neither EULA violators nor PayPal as an Internet police force doing online civil forfeiture.

The way to handle Netflix/PayPal is by international treaty regulation for nondiscrimination and uniform product quality. Netflix/PayPal is likely in violation.

Overseas users are in luck: treaty actions will only work OUTSIDE the USA. Kickstart a trade lawsuit. Any lawyer will work on contingency against deep pockets. Kickstarter only need fund initial research.
I’ve worked 80-hour weeks for the past decade (occasionally 100-hour weeks)

Wow. This if anything will screw you up. 12 hours of work + 8 hours of sleep per day 7 days a week leaves you with 4 hours for commuting, showering, making dinner, doing laundry, working out and relaxing.

Doing eighty hours per week can be wonderfully efficient - for a few weeks. After that you start to get sloppy, and soon you're performing worse than those doing a 40 hour week. Work a not a sprint, and not even a marathon, and more like running around the globe because you like to run.

Work shouldn't even be means to an end of becoming rich, and being rich without a respected job you're proud of is boring and hollow. Unlike prestige, once your income or wealth exceeds the limit where you have to stress about money, having more money won't make your life happier.
Ask HN: DO You Use AWS Lambda? Why? Why Not?
Folks,

this night I dream an architecture to build a "clone" of AWS Lambda.

The more I think about the more it seems reasonable.

Before to start coding and stuff, I would like to know if you guys are using AWS Lambda, what you like of the service and what you dislike.

What would it be your perfect Lambda ?

Thanks :)

Definitely agree. On an added note (about safe vs sorry) - while in this case I was "lucky" to have my hypochondria be correct, the vast majority of the time symptoms that I worry about are nothing. If I went to the doctor for every little symptom I got, that would be expensive and time-consuming.
Ask HN: Private blockchain implementation?

I often wonder if there is any argument to be made that completely eradicating the Guinea Worm, Anopheles mosquitoes, Variola major and Variola minor (SmallPox Virus) is not a 100% good objective.

My perspective (as well, I'm guessing, approximately 100% of humanity's, to quite a few significant digits), is that any significantly lower being that hurts humanity, or presents a threat, has no right to exist, and therefore we'll terminate its entire existence.

But, you can see, taken to its logical conclusion, that thought pattern could lead to less than desirable ethical behaviors.

Perhaps we draw the ethical line at the vertebrates. And maybe Octopuses.
Good work, keep it up :)
I don't know. From what I've heard it's about market rate. Not any higher than other similar companies (Google, etc.). Everyone I know who has worked there has worked there because they liked the environment/work.

I get so many symptoms on and off (which include numbness, aches, shortness of breath, chest pain). The way I bring myself to relax about these things is that I don't worry about them unless they persist for a particularly long time without any breaks in their occurrence. I actually expressed similar sentiments just now in another comment about the pitfalls of worrying too much.
Airlines buy fuel contracts far in advance. You're paying 2015 prices throughout 2016.

I might actually try these on an emulator. Relive the past for an hour. On a side note, the fact that coding is part of the curriculum in the UK makes me very happy. I went to my son's open day at secondary and some kids were at the computer lab learning Python. They are learning at 14 what I make my living on.
Airlines often enter into forward supply contracts for fuel to hedge against spikes in fuel costs, so the price of the fuel for a flight today may have been set a year or more ago ago. However, even if the airline benefits from a drop in the price of fuel, it doesn't necessarily mean cheaper flights. Airlines don't operate on a "cost plus" basis - they set their prices based on the competitive environment. If the price rises, the airline gets to keep the extra profit[1]; if it drops, the airline's profits suffer[2].

Hopefully, the current low oil price will let the airlines lock in lower fuel prices for the next couple of years and competitive pressures will start to result in lower ticket prices next year.[3]

Wow. "Introduction to Computer Programming" was quite literally my first intruduction to programming. I didn't have access to a computer until several years later, so I just wrote programs on a piece of paper.
I guess that part is inflated as you suggest, but you flew Qatar economy from LHR to BKK for I guess under 400gbp all-in. Even if the real cost of fuel was close to $100 there still not a lot of gold in the deal, the other mandatory fees essentially mean that Qatar have less than $100 per flight leg to cover their costs. Given Qatar is one of the best on this route I'd say you still got a bargain. BTW how was the dreamliner in comparison to the a380 iirc they were using 777s last time.
The best thing about old first-time programs is the naming. It can be quite revealing and unexpected when you remember where the name came from (or might have come). I liked the "psycho" program with its graphical glory. By name only it could've been nearly anything. I think I also might have had a program called "psycho" in the very early years...
Great suggestion, I do agree with everything you said :)

At any point in time, the level is fixed. You yourself propose fixing it at $100 for an unspecified duration.
Yes, the current 'maybe' implementation should practically break almost any properly written IO code.

At this point, it will only work for the most trivial of demo cases. Still IMO it's a cool demonstration of the linux ptrace facility. And if the author implements the missing sandboxing/emulation layer in a future version and switches to whitelisting instead of blacklisting syscalls I think it could actually run a limited number of programs (forbidding stuff like mmap and network IO).

I thought this technology would use the MAC address and SSID, but not the IP address because surely most access points have WPA enabled by default now? And that these find-my-phone apps use data from the phones GPS and 802.11 wireless to build up a cross reference database. Then again, maybe most Americans do not have WPA security enabled?
40 hours of solid, uninterrupted work is worth 80 hours of procrastination/interruption-filled work. You have to choose those hours carefully. I remember when I worked in an office, we would always go out to lunch at 12:00 and the resulting 3 hours would be destroyed for me by a food comma and the disorientation from leaving my desk for an hour.
YQ has nothing to do with the cost or amount of fuel for a flight. It is also possible to partially or entirely eliminate the charges using a technique called fuel dumping:

Yes, people who try and inject a little fun into their interactions are just the worst, aren't they? In a professional setting too. It's just shameful behaviour.

Not at all. The HFT debate has two real players: Large banks and large active investors (on the one hand) and HFT firms on the other hand. HFT firms profit by driving margins down at the expense of established players, and by reacting quickly to very large orders. Retail investors, however, benefit from the lower margins, and weren't placing very large orders. They're fairly clearly winners. (So are large passive investors. Vanguard is on record as being very pro-HFT, because it drives their costs down.)

One description of the HFT (from the always thought provoking Matt Levine): "It's an incremental efficiency improvement, with some opportunity for gamesmanship, that overall allocates some money out of the pockets of banks and hedge-fund managers and into the pockets of exchanges and HFT technologists."

That's basically correct. And as a bonus, the small retail investor buying twenty shares of Apple now gets his shares very slightly cheaper, which is kind of nice I suppose. (Unless you work for a large Wall Street firm who's revenue depends on retail investors paying high margins. But in that case my sympathy is quite limited.)
From https://frontendfront.com I send a newsletter every Monday with the most upvoted front-end news of the week.
The obvious point, which isn't really mentioned until halfway through can be distilled to one sentence. Life needs to include happiness.

If it doesn't, it's just unhappiness. That's what's toxic. At some point in middle-age you look back on years of unhappiness with (seemingly) only more ahead and then death. For many people that sort of realisation can spell depression, full on breakdown and even suicide.

And of course it's easy to read something like this and over-compensate. Healthy minds —like bodies— need balance. We need time alone, with our families, with our hobbies to relax and enjoy but we also need work to stretch us. Neglect either side of this ledger and you'll suffer.
From the website: "These books were written for 1980s computers such as the ZX Spectrum and BBC Micro. The programs will not run on modern computers."

Not true! They'll all run perfectly on RISC OS on the Raspberry Pi, especially easily on RISC OS Pico.

I remember several of these books very fondly, it's great to see them made available like this. Usborne Books in general are brilliant.
