This reminds me of my old chemistry teacher, we used to enjoy watching his demonstrations because half the time they didn't work. Excuses would be made about a bit dirt must have been in the test tube or out of date chemicals etc.

But it made the lesson interesting (we wanted to see it fail), watching a well made video is less engaging than seeing a live demonstration.

Good find. I believe Amazon allows you to sell ebooks internationally, I could be wrong though.
If most of your costs are USD and most of your clients want to pay USD why not open a USD account with your bank and be done with it?

Figure out the most fluctuation you could handle and put a note in your TOS that you will adjust the pricing based on USD/CAD exchange rates if they go outside of a certain window. Alternatively, you could bypass this calculation and just purchase a CAD futures contract from your bank.

Seriously, worry more about getting customers than how the USD/CAD exchange rate will vary over the next year or two and you'll do fine. It's more likely that the CAD will go to .80 than 1.20 because Canada exports 80% of it's goods to the US and a devalued currency is better for exporting countries.
I thought the point of removing the scores was to de-incentivize (??) people from posting for karma. Or, put another way, to improve the quality of comments.

I didn't think the goal was to remove the social benefits that come from crowd sourcing. Now, unless a comment has a negative score, we need to waste time to filter something that others could have already filtered for us.
I apologise; I am clearly not familiar with the current state of exceptions. I'm sure it's obvious that IANAL as well, but, outside of specific exceptions (of which salary disclosure is apparently one as of the last decade) at-will still means "any reason or no reason" (though, California isn't exactly the best example of "at-will"....).

Unless my knowledge in this case also happens to be woefully out of date, the burden of proof lies on the allegedly wrongfully terminated employee.
and if they say 'how would $Xk do', where X is a half of the market salary of a developer?

Congratulations. Your children will be about the same age difference as mine. It's a good age distance, although it has challenges along with the joys, the humour, and the memorable moments.

You may find yourself wanting to record those moments for the future. Photographs and video won't let you capture everything. You may want to start writing about them. Short essays about your kids and your family life, written in a poignant and/or humourous way, will both entertain your extended family and serve as an important record for years to come.

Rather than simply being about maximizing your "work related potential", the skills you learn in this process will lend themselves to all aspects of your life. When life calms down a bit, you can apply them to work if you wish.
It's pretty obvious that iPhone games designed to be controlled by tilt work well with tilt, it's not at all obvious that other genres of games work well with pure tilt controls.

It's also a bit premature to draw conclusions from kids at an age where their fine motor skills are still developing. They could be getting frustrated because pushing buttons is hard for them.
I disagree. I've never had an offer retracted. I'm not a "known superstar".

I suppose, though, I've never tried to get into Facebook or Google. And I suppose in those companies, with huge applicant pools, they'd chose somebody else if I indicated I only saw working for them to be equal to working for my other offers (unless, of course, one was one of them, and my other offer was the other).

I'm not sure how this would work. Perhaps you would first need to define the term "regular employee." In the U.S. the best way to define a regular employee is by the tax form. Generally a regular employee is considered a W-2 which means you have to do things such as pay into that employees social security (and other social programs) among other things. If your employee isn't a W-2 then he/she is generally a contractor.

Since an Indian citizen doesn't live in the U.S. then none of these sorts of laws apply. So, from the U.S. perspective, you would simply be a contractor and your services would be a tax write-off.

You specifically mentioned you aren't asking about companies which have a business in India, so that's out.

Conclusion: I don't know about Europe but I imagine it's the same as the U.S. Because you don't live in the U.S. you will always be a contractor and the only tax / legal implications is that payments towards your services are a write-off. You would be a regular employee in name only. You wouldn't necessarily receive any of the benefits that typically go along with the status of "regular employee."

Palytoxin LD50 (rat, intravenous): 0.089 μg/kg according to http://www.ncbi.nlm.nih.gov/pubmed/19505494
Sarin LD50 (rat, intravenous): 39 μg/kg according to http://cbwinfo.com/Chemical/Nerve/GB.shtml

So the lethal dose of palytoxin is ~1/438th of the lethal dose of sarin.

Interesting review.

I didn't find your "economic argument against child sexuality" convincing however. (I understand you are positing claims about societal beliefs as opposed to your own)

"... we’re unhappy when people reproduce and can’t afford their offspring. So we call people who mostly aren’t economically viable children, even when they’re physiologically and psychologically not..."

Being under 18 may be one indicator of financial viability - although many children are born into privilege, are beneficiaries of trust funds, are financially self-sufficient.

Living on welfare benefits (or perhaps even minimum wage?) is a much stronger indicator of financial viability, and yet we don't see wholesale sterilisation of the unemployed or even any organised public policy discouraging sex between employees of the fast food industry.

I suspect that (as usual) there are more complex factors behind "age of consent" legislation than rational economic principles.

Understand the following restrictions from the manager's point of view;

a) everyone thinks they're smarter / better / faster etc than the folk around them.

b) everyone thinks they deserve "above average" pay.

c) there is always someone else at the company making more. There's always some company down the road paying more.

given these constraints there are always going to be people who think they deserve, or indeed want, more. No matter what he does a bunch of people are gonna be upset.

Reminds me of the time I was managing 3 developers, and all 3 independently came to see me to complain they weren't being paid more than the other 2, when in fact they worked harder than the other 2 and were more valuable. Of course they measured "worth" differently to me, but whichever way it turned out 2 were gonna be unhappy.

I tried to read this but the Scribd reader hung up on me after a few pages and all I got to see were blank pages (I'm using FF4). Would it be possible to compile some of the comments in a "Sample.pdf" file and directly link to that instead?
The book What Technology Wants by Kevin Kelly (I've got about 40 pages left in it) makes a compelling argument that it is (though it falls short of "proof," which may be impossible in this case).
I think I'd really enjoy the read.

It would have been a bit nicer if the great comments were accompanied by some good design/typesetting (generate latex?) and an alternative format (epub).

There are a few solutions based on princeXML that can take easily generatable HTML+CSS and convert it to pdf (example: http://www.alistapart.com/articles/boom ).

While the Prince license might not be the cheapest, there also is a webservice that does the conversion (http://docraptor.com/tour)

AOL Shuts Down Software Blog Download Squad
I took the first number they offered ($48k/yr I think). That was a HUGE mistake, even in those times.

That's not the worst mistake you could have made though. For my first job, I was interviewing with a company that a college acquaintance was working for. Through a mutual friend, I had a rough idea how much this acquaintance was making... or so I thought.

When the salary portion came up, the company recruiter asked me how much I was expecting. Being incredibly naive about such things, and thinking I knew how much they were willing to pay, I gave a number.

What happened next is something I'll remember in every salary negotiation for the rest of my life. The recruiter apologized, and said that they simply didn't pay anyone that little, and she told me their company minimum and asked if I was ok with that. Sheepishly, I accepted, knowing that I had just completely screwed myself and I really was no longer in a position to negotiate for more.
He said it's the same as

*(index + arr)

which is correct.

C pointer arithmetic already accounts for object sizes.

And it's sizeof, not size_of. And

arr + x

is completely different from

x + *arr

And it's a series of "values".

Some brief background…

Google Map Maker is a map crowd-sourcing project which was originally targeted at countries with poor commercial map coverage. It produces a closed end product [0].

OpenStreetMap (OSM) is a map crowd-sourcing project which produces an end product with an open data license.

Advantages of Map Maker include that Google can create maps derived from commercial satellite imagery products, Google has better mapping infrastructure, and maps are eventually integrated into Google Maps.

Disadvantages of Map Maker include a closed data license, restrictions on use (for example, no competing with Google), and a more opaque editing process.

Meanwhile, OSM has an open license (albeit a controversial one) and a broad contributor ecosystem. For example, Yahoo! has been generous in hosting satellite imagery for use by OSM for crowd-sourced mapping.

The OSM community has also been particularly involved in creating maps in disaster and humanitarian situations, such as after the 2010 Haiti earthquake.

After the Haiti earthquake, there was some controversy over whether to use Map Maker and OSM among aid groups, NGOs, etc. [1] The restrictions on use of Map Maker data was a key concern.

I'm sure that's a mockup, or a prototype at best.
That is an awesome writeup, wildbunny. We all suffer with facebook's temperamental platform. There are a couple points i would add actually:

- At this point it's impossible to maintain virality without using "game dynamics", i.e. some sort of manipulative tricks that will persuade users to post things to their wall. Unfortunately, this is only possible for game apps (and is something zynga has perfected). It IS still possible to maintain virality, but you also need to complement it with advertising.

- There are bugs in facebook's bugzilla that have been lurking for years. Facebook tends to push buggy code at least every week,; sometimes bugs make apps unusable for days.

- Accidents happen more often than not. Last month, facebook removed 50000 of our users from our game for one day.

- Adsense is the best advertising solution, not just because the payouts are 2-5 times higher, but also because the ads are safer and more useful. Since we switched to their "approved" advertisers, we have been receiving reports about malware ads. Unfortunately, their nonsensical terms are designed so that only small advertising shops would be willing to participate.

The overall experience has been good, but lately it's getting insufferable. It's odd that facebook has chosen to monetize its platform from facebook credits at the lowpoint of the platform. We have already put our games on maintainance mode, and embarked on other endeavors
Shirley Maclaine
Says something about the media that they mention in passing that 13,228 people have died, 14,529 are missing and over 150,000 people are homeless. All from the earthquake, not the nuclear plant. And yet the focus is on the nuclear plant, which fortunately has not yet been responsible for any deaths and if we consider Chernobyl the worst case scenario, will have a much lower death toll than the earthquake.
I'm not saying it's not important, but what happened to reporting about the effects of the earthquake? Did that just become boring news?

Ask HN: Launching a niche community - coding choices
We're preparing to launch a niche social network for Media Professionals later this month.

Since this is going to involve mainly professionals, we're planning to offer only serious usage type of functionality, at least in the initial phase (e.g. profile builder, forums, group formation, private and group
messaging, member directory etc.).

While we already have most of the features working now (with proprietary code, stable and working satisfactorily), we're wondering if we should ditch this in favour of a ready-made SN platform such as ning - or some other one.

What do HNers suggest? Which way should we go? Roll our own or go ready-made? If ready-made, why, and which one?

Please share your views.

Amazon Unleashes $114 Ad-Supported Kindle
The problem is that as a group of geeks get diluted by newbies the intelligence level of the group goes down. As the intelligence level decreases the ability for this group to filter for the conversations previously highly voted decreases. More intelligent people filter for more intelligent stories and comments. (Is reddit a worse community? No. Does it have a different audience? Yes. That is what is happening here.)

I know this is an offensive idea, but you simply have to decide whether to cater for the elites or the lowest common denominator. As time progresses the people just joining now will look back on this time as a golden age of HN -- it will get worse -- and in the future there will be a new wave of lower intelligence HN'ers. That is how it always is.

The solution I would prefer is (1) allowing users to curate their own experience with far greater granularity than allowed on a site such as Reddit. That is, use twitter like ideas of followers and lists. Allow us to choose who we see comments and stories from. I care about the votes from these people much more than somebody who just joined a couple of weeks ago and hasn't programmed or owned a startup company. (2) giving users with popularity in the community, moderation power similar to the kind found on StackOverflow. The power to close topics. Respond to bad usages of the vote button. Respond to flags. Perhaps even the power to moderate comments.
It's good, but it may make a mediocre reply to the top comment even more "profitable" (in terms of both karma and attention) than it is now. Displaying '10+ points' (only) may be useful, and will also make finding the "good" comments easier.
I think it's more to avoid groupthink, posting for karma would only make sense if you couldn't see your own scores, and also, it would probably involve removing the karma leaderboard.

Boston and Cambridge SEO Meetup - Content Marketing Tips
"I thought the point of removing the scores was to de-incentivize (??) people from posting for karma."

How does it do that? People who post comments are still going to get karma for upvotes.

"I didn't think the goal was to remove the social benefits that come from crowd sourcing."

Comments which get more upvotes still tend to drift to the top of the screen over time. So there is still some indication of which comments probably got more upvotes (they're the ones near the top of the screen).

Whether that's really much of a benefit or not to revealing a given comment's upvotes is debatable. Apart from some really trollish or contentless comments, I don't think the number of votes on comments is particularly indicative of their quality.

As pg stated in the original thread which motivated the change to hiding the upvotes for comments:

"The problem has several components: comments that are (a) mean and/or (b) dumb that (c) get massively upvoted."

http://news.ycombinator.com/item?id=2403696

Hiding the upvotes that comments get reduces the tendency of people to vote with the herd. It also gets people to read more comments and read them more carefully.

I think overall this is an improvement, but not an unqualified one (for reasons discussed elsewhere in this thread and others). As I've stated elsewhere, it might be further improved by revealing the number of votes a given comment has gotten to each user who votes on that comment only after they've voted on it. That will encourage voting and still discourage voting with the herd.
