I realized exactly this when I wanted to write a backup script for some of my client's websites.

My usual process had been to 'manually' backup using rsync, which was a matter of cutting and pasting the commands from a text document.

When automating, however, I realized I'd also have to check if certain files (db dumps) were present, and of course if the script itself succeeded.

I then realized that in this particular case, the simple cut and paste approach was perfectly fine, because: 1) it would take months for the time spent automating to be worth it compared to a quick cut and paste, and 2) it was much safer for me to quickly scroll back in my terminal and see if the particular files were present.

Now I wouldn't generally recommend my approach, but in context it made sense not to automate, and yet I felt a 'need' to automate anyways.
Well the notation lets you tell how specific you are being about a number. Instead of saying "about 1,000" you can say 1 * 10^3 or 1.00 * 10^3 which give different amounts of information. So it's not exactly the same as base-10. And if you're talking about really big numbers, it's nice not to drag all those 0's around. It's just as big a step from .......... to 10 as from 10000000000 to 10^10.
"as they should be able to"? That's it? we are living in a world where privacy and freedom aren't ours to demand? Governments "should be able" to kill off our freedom? I haven't noticed we've gone that far away.
That also started in Greece after they announced the austerity measures. (2008) It's still an ongoing thing, and there is an organisation called (WeDon'tPay) that does that stuff, they'll gather and they will not let people pay any fare. This happens also in Tolls, that have been abused by contractors and the goverment and 60 years after the complitation of the road they still have tolls.
$180 isn't much of a fine, especially since it can be covered by 50% of a $15/month membership charge.

$180 is a significant fine, if you're poor. I've always liked the idea that a fine should be generally tied to your level of wealth, perhaps with a floor so it's not pointlessly low. If the idea of a fine is to deter repeat activity, wealthy people should be equally deterred.
Pretty generous house to provide even wagers:

> 0.01 CHA	1%	99X	-0.01 CHA
> If travelers keep their side of the agreement, the group will cover any of the roughly $180 fines that might result.

What an ingenious and devious application of risk pooling.

Imagine risk pools being created for other fines, like tax evasion penalties or speeding tickets. I wonder if such agreements are legal?
I think you've misunderstood. There's no witch hunt from this end. You seem to be interpreting questions as personal attacks and lashing out. Others are responding to that appropriately.

I know which paragraph of which publication you're referring to but it's protectively marked and as such neither of us will be posting it on here. That's where the Official Secrets Act comes in to it.
To top this off, SL (the public transit company in Stockholm) adopted the MIFARE Classic cards which are now being hacked. Much like this:

Ok, thanks for the feedback and the edit. I thought that "Show HN" was also there for ideas.
It's definitely base-60. Carrying from one place to the next happens on powers of 60, even if you write the value of each place with base-10 numbers. And if you have an analog clock, you don't need base 10 at all.
According to wikipedia, they are a far-left group who "advocate self-reduction, where the price of the service is determined by the consumer. Whereas in other cases this is done in agreement with (at least some) employees of the service provider, in the case of Planka.nu fare-dodgers are encouraged to evade fares without seeking permission."

So I would guess it is mainly a matter of principle (not one that I share). Wikipedia also states "ticket fares in Stockholm have increased dramatically over time. By one measure—single ticket price for a 10-kilometre (6.2 mi) journey—Stockholm has the most expensive-to-use public transport in the world, as of March 2009"
Traveling the DC metro from baltimore literally cost me like $2 one way. It would otherwise be a 50 mile drive.

So I could either spend roughly $5 on the metro, or $20 in gas (plus a long ass commute and gridlock wait time). For what you get, most metro costs ARE planned to be at a significant advantage to most people.
beside the other reasons, a simple alternative might also be that users with high reputation usually are known by the regulars. If you recognize someone’s name for posting a lot of interesting stuff on your favourite website you probably help him out before other guys.
It's said that german finance authorities use it for revealing tax fraud.
You get other problems if it's completely free; homeless people start living on public transport, drunks using it for extended napping.

Fares also act as a congestion control mechanism. Higher rush-hour and central prices push information into the rest of the market.

Also, cars are not the only alternative to public transport. In central London where I work, cars face congestion charges that normally exceed the cost of a day ticket on public transport (if a single occupant). But bicycles and motorcycles are not charged, since they don't create congestion in the same way. Bicycles are cheaper than public transport, and governments have an incentive to encourage their use, since they hopefully have health benefits too - reducing healthcare costs.

Motorcycles can be cheaper than public transport too, but the calculation is much more complicated, owing to depreciation, maintenance, increased risk, increased fun factor, etc. A scooter is my personal choice.
How about quarter-imaginary? https://en.wikipedia.org/wiki/Quater-imaginary_base
The distribution of the digits of pi and e is not the same as the distribution of first digits in a set of numbers; only the second is subject to Benford's Law. While both normal numbers and Benford's Law are interesting mathematical objects and deal with distributions of digits in a number, that is the complete extent to which they are related.
What? Oh shit... I better start packing...

Maybe it's that the explosion in programming careers coincided with a bunch of kids that left school in the run-up to the last tech bubble? They are mostly in that range. Those are the ones who were growing into the web world (and were more likely to stay technically engaged).

I expect we'll continue to see that age slide a bit, though due to the senior programmer income plateau (and supervisory experience accrual), you also have the move to management effect. Many good programmers will become leads, architects, managers etc.

I have no idea why you would think a programming career ever ends in relation to an age? It may also be that people 35-40 don't want to work at companies or with the lifestyle you see around you?
NUTRI – SIGHT LLC OPENS AND ANNOUNCES MACUTAB EYE VITAMIN
Nutri-Sight is a nutritional supplement company dedicated to the research and development of vitamin supplements that benefit eye health. Nutri-Sight was formed in March of 2013 by Dr. Stephen Wiles. The flagship product of Nutri-Sight, MacuTab, was developed from extensive research of the AREDS and AREDS2 study conducted by the National Eye Institute for the improvement of visual acuity - specifically in individuals with age-related macular degeneration.
Because we use accounting to measure how equipment is used and decide how to allocate resources efficiently.

Without accounting, we can't tell where to divert resources to maintain or improve the equipment. It's also not possible to limit the use of the equipment beyond its stress limits without using money. Trains in particular require additional staff to handle high passenger loads. Some passenger trains are not set up to handle high traffic loads. Charging money limits the ridership to the people who want/need to use the train more than others. It also limits ridership of likely bad actors who will do things like key the windows or spray graffiti in the tunnels or on the trains themselves.

>Why would city spend significant resources to discourage usage of public transport?

Because then they would otherwise need to rely entirely upon the political process to maintain needed funding to the system, and there would be other spill-over impacts to the quality of the rail network.

>Do they really prefer for the people to buy cars and stand in traffic for hours on overcrowded streets and subsequently be disgruntled and pressure local governments for more roads?

I'm unfamiliar with road policy in Sweden. I imagine that the fares are paid through taxes on gasoline, tickets for driving violations, licensing fees for commercial vehicles, and other fees. The two transportation methods are not completely interchangeable. You can't run heavy freight on a passenger rail line. It's a bit easier to have shared freight and passenger traffic a highway. Expanding rail coverage to other regions is much more capital intensive than expanding road coverage, and much more challenging to estimate (see: the underutilized light rail projects all over the United States).

In a magical world of infinite resources and immortal human beings and infinite time, then there would be no reason to charge fees on anything. Because we live in a finite world of finite time and resources, we use money as a measurement tool to make better decisions with how we allocate our resources.

>Why only public traffic commuters pay if all benefit from the fact that they are not on the street crawling in 1.5 tonne of steel each?

Not all benefit at all times to the same degree. Also, it is probably also partially funded by taxes. That people are rebelling probably indicates other problems with the system outside the scope of the article.
It obviously does not help when you hit you little toe on the leg of a table, but it helps with more abstract problems. Realizing that philosophy can neither be right or wrong (only illogical) makes for a more relaxed life because you don’t have to worry about “the big questions”. You can just pick the answers you like.

Client-side loaders support plugins too. Less, Sass, CoffeeScript, ES6, literally anything you want. I don't know why you would accuse me of not giving Browserify a try (I have several projects that use it, but I guess that's not giving it a try) when you didn't even know that client-side loaders support plugins.

Hell, you could even use a client-side loader exactly as you are doing with Browserify/Webpack. Just set up a watch task that builds unminified and there you go! It's just nice that they aren't dependent on a cli process. But unlike you, I'm not trying to convert anyone here, just pointing out that there are advantages to using client-side loaders. For example, it promotes separation of client-side code from server-side code. Using the same package.json file for both promotes bad practices like developing with the server running and writing code that's not easily testable without the server running.
These aren't games, they're just random number generators. Things that hold peoples attention give the illusion of more depth than P(payoff).

The Bitcoin protocol already has a blockchain-validated (non-Turing) scripting language. You could probably write genuinely interesting games in it, that are financially self-enforcing, without any new protocol needed.

https://en.bitcoin.it/wiki/Script

(Digression: are there any technically-interesting protocols built on top of BTC script validation?)
Not so. I tried something similar to this with poker and it flopped. 4 months of coding down the drain. Turns out, gamblers are generally addicted to action, not profit. They don't really care about whether or not they have an opportunity to run a table and profit.
I believe you're thinking of FTP, not HTTP. Content is rather more than documents, and spans from animations to interactive presentations, visualisations and demonstrations, games and ... you get the idea ;)
The title in the sample image looks like "hra sans 3.1", with a really funny-looking 'h'.
Relatedly, if you want to analyze PGNs, I put together some Python code that can analyze PGNs in combination with a chess engine. It can also draw chess positions, if you find interesting positions you want to programmatically draw:

https://github.com/pickhardt/chessbox

I'm kind of hoping someone will do a thorough analysis of the types of moves chess grandmasters make during a game. For instance, here is a chart from a GM book that categorized moves into four categories: http://imgur.com/BMOElXN
I work at a company that helps companies sell their rough diamonds, so I've seen the seismic shift in the rough diamond market over the last few years. There's a common belief amongst those in our area - "the diamond industry has changed more in the last 5 years than it did in the previous 100". That's probably an understatement.

The decline in market share can't be understated on its effect on the diamond industry - DeBeers market share has gone from 90% to 40% in the past 10 years, and as a result, their pricing power has disappeared.

Before, DeBeers had a take it or leave it price - sight holders essentially had a choice to accept the price DeBeers offered, or basically go out business. Now, any company who wants to buy rough diamonds has the ability. Whereas most people here have commented that the prices of diamonds should decrease, on the contrary, prices have increased. More people have access to the diamonds - demand has exploded.

The decline in market power of DeBeers has been an exciting time in the industry.

If be happy to answer any questions - it's a fascinating industry.
You could only truly compare Source Code Pro if the designer made Fira Sans Mono. I wonder if he has?

That'd fix the lowercase r problem, I would think.
No, prices will not go down. Demand has skyrocketed, see my other post for reasons why.

I'm really on the fence about that argument.

On the one hand your argument makes a lot of sense to me, but on the other hand using an email provider that is not one of the popular ones might in itself make you seem more suspicious.

And intercepting your email correspondence, no matter the provider, might be so trivial to the intelligence agencies at this point that they might be doing so already anyways. It's not unlikely that they'd be 'scanning' Fastmail email more intently than gmail, precisely because of the kinds of people that have security concerns.
I think Knuth's up-arrow notation (see http://en.wikipedia.org/wiki/Knuth%27s_up-arrow_notation) can be considered a newer way of representing numbers, and it continues the progression you describe in that each the older notations are usable for small numbers, but the newer notations are better for large ones: Knuth's up-arrow notation is only really required for truly gigantic numbers and as a result I don't think it would be generally useful. (As generally useful numbers aren't that huge.)
> homeless people start living on public transport

That isn't a problem with public transport, it's a problem with social services.
I don't mind service providers giving information to law enforcement provided there's due process and some court oversight. You can "demand" freedom all you want, but if convicted of a crime, the government should still be able to put you in jail.
I guess that the patent / IP infringement indemnity clauses in business contracts come close to that. The company offering the service takes the risk of being sued, but offsets that with money earned from the contract. Quite popular and apparently legal.
No, you would have to do that before being sued, for obvious reasons...
Demand has increased for many reasons - more companies have access to rough diamonds, Asian consumers (especially Chinese middle class) are becoming believers in the "a ring means engagement" marketing campaign, and the general improvement in the world economy has led to an increase.
They really need to make a Windows version. I will switch from Adobe Photoshop in an instant.
That only works because no one else has access to SpaceX rockets to reverse engineer how its built and how it works.
It's still a problem for the public transport and its users though.
If I run an ad campaign, and tell Google to show my ad to a specific demographic of users, then I know that anyone who clicked on that link is (most likely) in that demographic.
Here's my explanation : assuming random distribution, the probability of finding a star at a given distance is proportional to the area of the sphere having that radius. So it follows a square law.

Correct me if I'm wrong, but I think any function with an increasing rate of change (ie. second derivative > 0) will yield a distribution with the same ordering of digits as Benford's if random numbers are taken from it.

The attacker can do whatever she wants. You can't prevent her from doing anything. But maybe you can elaborate on what you mean with "each power of two". When trying to compare with zero (what zero?), keep in mind we're talking about a probabilistic cryptosystem. The machine is just an application of the underlying scheme, so it's not the machine that provides the atomic functions.

To be precise, the state of the machine includes the flags, the PC and memory. It's easy to implement a simple stack pattern in circuits but you don't need it in order to implement arbitrary functions.

We already published the solution for encrypted memory access and encrypted program flow control (without unfolding) but halting is an issue you (at least to my knowledge) cannot solve under the assumptions we made.
What I was wondering specifically was how the average rating varies by year. My hypothesis was that it has gone down over time as it has become easier for games between less skilled players to get into databases.
It's not difficult to evade the paywall, especially for this (skilled with computers) group.

Actually, the original article the tc-story summarizes is at http://lmjabreu.com/post/why-and-how-to-avoid-hamburger-menu... .

And while I'm not a big fan of hamburgers as well, proposing a scrollable tab bar as an alternative is.. a bit strange.
Well, Java does have TCO already, just depending on the JVM you're using. J9 supports it, just not HotSpot.

A great case of cascading failure and bad decision making. A few things stand out.

- They made several bad mistakes. The tag line of the article said, "and how grit ultimately got the group out of a frozen labyrinth" but it was luck, not grit. The bad decisions were downplayed in this write up.

- They didn't have the right gear and weren't prepared (e.g. keep at least some water and batteries close to your body). One energy bar?

- They shouldn't have pushed on at night. Even for a day hike in the snow I carry a shovel and a couple of foil blankets and know how to rig a shelter. They would have done better to stick together (not to split up), know ahead of time who makes the final decision, and to have waited the night out.

- I don't remember the white mountains as well, but the places I backpack in winter (e.g. minnesota, california, new mexico, colorado) I use a topo and a compass and only use the GPS for back up.

- the three times I've felt "wow, there's a good chance chance I won't survive this" my overwhelming thought has been embarrassment at my own stupidity. Two of the three times the initial failure was "set out too late." And it was always multiple, cascading failures -- typically you should be able to deal with one or two things going wrong -- same as with engineering.
I agree (there was a time, maybe 10 years ago, that ~$60 was my weekly rent and I still ran arrears), but my girlfriend vehemently disagrees for reasons I don't fully follow but do respect (she's an economist by profession, in healthcare microeconomics, not macroeconomic weather forecasting).

It had something to do with maximizing overall welfare / utility for society. She's very touchy about it though, finds it hard to talk to me about it because she thinks I sound condescending when discussing it :) She also rejects the declining marginal utility of money as an axiom. And she rejects the concept of irrational economic actors; economic actors are rational by definition, therefore all their actions are rational, it's just your theory of their action that is wrong. You can imagine this doesn't make discussion easy :)
There's no question that gambling addictions are very destructive.

But that applies also to: alcohol, smoking, drug use, eating, sex, extreme sports, working out, investing in the stock market, climbing mountains, entrepreneurship, there are probably even a few people so addicted to HN it's ruining their lives.

If you seek to eliminate sources of destructive behavior, you're also going to eliminate a ton of genuine life experiences for those who are capable of moderation, maybe even until there's nothing left. Lives are ruined when people die climbing Everest after all.

I'm not interested at all in gambling, but I'm very concerned with where the slippery slope is headed.
To add to vbuterin's comment:

I think a mix of a tab bar and a hamburger menu is a good solution. Put the most frequently used items on the tab bar and then have a hamburger menu for everything else.
