lobe··on Ask HN: Moving to the USA with a chronic health condition
That pretty much answers it. I had no idea about the exchange, which alleviates most of my concerns. Thanks a lot
lobe··on “One billion people used Facebook in a single day”
If you wanted to go after photos for everyone I would agree with you. Probably just as interesting would be grabbing everyone's private messages, and although a large dump, would be nowhere as hard to store. A further option would be to filter whose photos you steal, so you only target celebrities and/or the rich and famous for maximum effect. It all depends on the aims of the hacker, but I would imagine you could make a devastating attack without stealing all of Facebook's data
lobe··on Ask HN: Who is hiring? (August 2015)
Awesome to see some Sydney companies here. Product looks really interesting as well. Best of luck finding someone
lobe··on Ask HN: What happens to the founders of startups that fail?
That first part isn't fair to the startup founders. I know a couple of founders of failed startups who wrote post-mortems on Medium, and then when it surfaced on HN the comments were stating that the founders were glossing over the important issues. In both circumstances the post-mortems outlined clearly why the company failed, it was just that readers saw a side to the story which the founder didn't expand upon (either as they didn't feel it was important, or out of respect to those they worked with) and assumed there were secrets hidden there that explain the failure.

I knew the full story of these startups, it was as told in the postmortem (one of which explicitly stated "we failed because of X"). Judging by some of the comments I read, some people don't want to believe the truth that's told to them. They assume they know more about the situation than the founder that lived it.

lobe··on Ask HN: What are other ways to monetize mobile games beside freemium or ads?
I have a friend who made several web games that went viral (i.e. he is from Australia, and when I was in Sweden I saw people I didn't know playing it in the lecture). Very simple clones of other games in terms of mechanics, however he wrote them himself and made them topical to current events and pop culture. He put a link to his email and facebook in the footer (he had barely heard of github), and got several job offers from it.

Note this guy was studying electrical engineering, but decided to pick up coding himself. These games got great publicity and landed him the job within 6 months of learning to code.

If your game is trivial, boosting your profile from it can be a much greater reward than monetisation. Granted, this advice isn't as helpful if you plan on being an indie game dev.

lobe··on Ask HN: What tips do you have for interns?
Sometimes not even challenging work, but sometimes menial work that is below others.

Every internship I have had, I was with a team that tried to give me the best experience I could, and never gave me boring or menial tasks just because I was the intern. In fact they actively avoided doing so and did these things themselves.

On my first internship there was a task that came in. As part of a security audit, we had to verify that all ssh keys that had access to sensitive infrastructure. That had to be done by hand, by running around and finding these people and checking their keys manually, which was nearly a days work. I volunteered to do it, as really that's the sort of stuff that I should be doing as it would be wasteful for the others to be spending their time on it.

Things like that got me a lot of respect. As an intern, you need to make the lives of those you work with easier. If this means occasionally taking some menial work or writing scripts to automate their tasks.

lobe··on Atlassian Takes the Gay Marriage Ruling Too Far
I suggest you don't go to Stack Overflow for the next few days then. I have no issue with comapnies showing their support in this way, but I can understand why others don't agree. Both the argument for and against companies showing their support for gay marriage have valid points, and I don't think I have much more to add than what has already been said at http://meta.stackoverflow.com/questions/297859/can-stack-ove...
lobe··on What Happens to Home Prices When Technologists Come to Town
I definitely had the eureka moment when I was younger. When I was in high school I worked with my sister to sell t-shirts that we designed online. The shirts were designed in photoshop, designs given to our supplier who printed them on demand to ship directly to our customers. Shirts were listed on eBay, payment made through paypal or direct deposit, and all communication with customers and suppliers was through email. At no point did we touch the product or even have a phone call with anyone.

After a couple of months we took out our first profit, which I think I spent some of it on an ipod classic. I was 14, and through clicking buttons and moving my mouse I now had an ipod in my hands that was all mine. That was magic.

lobe··on Uber Closes in on Its Last Frontier: Airports
When I was in Europe last I assumed the cops just let all of that slide. That was until I got to Florence, where I saw undercover cops arrest a group selling prints outside the Uffuzi, complete with crash tackling those that tried to run away.
lobe··on Hello, World
No, there are two different coins. So if Bob flipped heads (which Alice guessed tails for) then they lose.
lobe··on Why Some Men Pretend to Work 80-Hour Weeks
I'm an Australian who spent 6 months last year in Sweden. I definitely got the impression that companies needs came second to the needs of individuals. Here in Australia, it is much more balanced, depends on your circumstances. My American friends tell me the US is the other way, the company comes before the individual.

If you are in the driving seat for your career, I certainly feel that the USA provides more opportunity. However for the ~70% (random guess) of people who don't have the luxury of being selective with their jobs, the Swedish model looks extremely appealing.

lobe··on Project: A Simple Operating System
There are pros and cons, however I think this course has its place. It is for people who know they are good at their degree, but are looking for a challenge rather than easily coasting. In this respect I think it is fantastic.

The other side is that it is brutally hard, consumes a lot of time, and leads to a lot of dropouts from the course.

It is purely an elective course. Everyone who does it knows what they are getting in to, and then come out the other end knowing they've passed the test and recommending the course to everyone else. Given that it is one of the most highly praised computing courses at UNSW (along with Security and Algorithms), it must be doing a lot right

Note this is just based off friends experiences. I have never done this course as the timing was never right

lobe··on Project: A Simple Operating System
This is considered the hardest computing course at UNSW (with the possible exception of the security course). It has a reputation for being brutal and breaking lesser people. 'Survivors' get a t-shirt proclaiming this fact.
lobe··on UK trader in fraud arrest over US 'flash crash'
But that price discovery should reveal the price that the underlying security is worth.

If shares were only traded based on what other people trade it for, isn't that the blind leading the blind, and the price it is traded for will have little grounding in reality.

I have several issues with HFT, however 'spoofing' as it is described sounds like it should be perfectly legal to me. If a player wants to trick the market, it is an irregularity that should be capitalised on by someone with a better understanding of the true value of the security

lobe··on How Coursera Competes for the Best Talent
You say it's deceptive, but surely anyone who is contacted in this manner can read between the lines and see it is about recruitment - what other goal would the business have in mind?

And as for the suggestion of making an offer up front, I feel that is jumping the gun. I'm sure the business would already have a good idea of what figure to offer, but if you discuss that before anything else I see several scenarios playing out.

1. Candidate declines. A good outcome, quick and painless 2. Candidate accepts offer. Bad situation - do you really want a candidate that doesn't try to sell themself or get a better offer? 3. The conversation is hijacked by discussing the offer and terms rather than the position. This is not productive, and the candidate has all the leverage. May or may not end with an agreement 4. After more talks you decide the candidate is not a good fit. You retract the offer, and candidate leaves with a bitter impression of the business, feeling he was lured with an impressive offer.

I agree that the business could be (should be??) more upfront, however an immediate offer is not the way. Perhaps instead give a realistic ballpark and go from there.

lobe··on Newcomb's paradox
Since it is a rule of the game that the predictor is infallible, anyone with $500,000 would take that
lobe··on Ask HN: Coming to the USA for a study exchange, where are the tech hubs?
I want to use my time in America under a student visa to meet and interview with potential employers who would then sponsor me for the appropriate visa. The grad recruitment process in Australia is usually 6-9 months before you start, I assume it is also similar in the states
lobe··on Clearing the Air
For an attack on false information, they seem very light on the facts.

> False claim: We picked a really stupid place to put solar panels

They put forward several arguments as to why solar roads would be a good idea. The problem with this is that it does not address the opportunity cost - the argument should not be why solar roadways would be good, but why solar roadways would be better than solar rooftops or solar fields. The complete lack of figures here is not helping them.

> False Claim: Solar Roadways is going to cost $60 trillion dollars

OK, so it won't cost $60 trillion, so what will it cost? Again, no numbers, no estimate, just "we don't think it will cost $60 trillion, but we can't substantiate why"

> False Claim: Asphalt roads are cheap and maintainable

Not going to argue the claim (whether it is true or not). But what research have you conducted into how Solar Roadways would be better, other than the (unsubstantiated) claims that the roads will pay for themselves.

> False Claim: we can't afford to heat roads

They lead with ""Over 70 percent of the nations roads are located in snowy regions, which receive more than five inches (or 13 cm) average snowfall annually. Nearly 70 percent of the U.S. population lives in these snowy regions". Then follow up with "Each year, 24 percent of weather-related vehicle crashes occur on snowy, slushy or icy pavement. Over 1,300 people are killed and more than 116,800 people are injured in vehicle crashes on snowy, slushy or icy pavement annually." Finally concluding with "Does the current system of snow removal sound cheap to anyone? What would saving over 1300 lives and preventing over 115,000 injuries per year be worth? Not to mention medical bills, vehicle repair, lost wages, etc."

I am sorry, but that is not how it works. That is nearly implying that no one will ever die on a solar roadway. I agree that there may be benefits, but the article has used statistics in a way that is meaningless.

> False Claim: Glass is softer than asphalt

Where to start on this. Hardness is a horrible characteristic to choose a road surface for. Sure, glass may be harder, but will it be more durable? Cracks, structural weaknesses and fractures all will cause problems in glass if all you are worried about is hardness. It's been a while since high school science, but I still remember this. Asphalt doesn't need to be hard, as if it is scratched or compressed, there is just more road base beneath it.

There are many more problems with that article, but that should do for now. I am amazed that Solar Roadways would publish a rebuttal article in this style that is so light on the facts and that chooses claims selective to their cause (such as the hardness of glass). I feel sorry for those that have committed on Indiegogo if the calibre of the author is indicative of the calibre of the company.

Despite all of the above, I will give them credit for using "Clearin' the freakin' air" as a title for the article

lobe··on Magnus Carlsen is World Chess Champion
It was the best option in both cases. He was in check when he took the queen, so the queens had to swap or black would lose his queen. At the end Anand traded his knight for the pawn as a king and knight (black's material) can't win, but a king and pawn (white's material) can, so it is in blacks best interest to swap.
lobe··on The Cost of an ACL Injury
This is amazing to me. I am from Australia and did my ACL when I was 15, and the cost was around $3000. It was an overnight stay in hospital, the only costs not incurred for the actual surgery and operation were MRI's and physiotherapy. How that could cost 20x the amount in America, I could not possibly fathom.

It is always a struggle for me to understand how health insurance is such a major expense in America, but when relatively routine surgery such as an ACL repair costs that much, things are put into perspective.
