The capabilities they outline seem to vary widely in potential difficulty. I think 3 of them are clearly the most difficult:

Mars landing tech - we've never landed any really large weights on a planet with gravity on the same order of magnitude as Earth and no atmosphere. This is gonna be tough to build and expensive to test

Liftoff from Mars - What kind of craft will we need to get the crew back to Mars orbit from the surface? Will we be able to land it ready for launch, or will it have to be partially constructed and fueled on Mars? How will we build the infrastructure needed to do that?

Technology for living on Mars for an extended amount of time - if people are going to be living on Mars for months or more, as seems likely, then we're going to need to build a much more substantial habitat on Mars than anything we've ever built before. How will we go about transporting and constructing that?

Everything else sounds like something we've already done, just expanded a bit, like bigger rockets, nicer space suits, better radiation shielding for the interplanetary craft, etc.
Curious what this has to do with protocol buffers?
I agree with you that the names 'melody' and 'chord' would be more appropriate here. I think of dung when I see 'scat'.

I'm excited to use this, though, and will definitely be reassigning those names to something else at the top of every file.

Asymmetrical peering has been the rule since the 90s. Think of it as fan-in and fan-out, each of which has different dimensions.
Your homepage is as clear as mud. It says "Delightful ... annotations" and "drag in a presentation or click anywhere" and finally "see a sample"
But it doesn't tell you WHAT you actually do. You could easily add a couple lines of text with an explanation, without adding any clutter. Links to a FAQ and More Info and About would be helpful.
further down you have "click here to upload a file" WHY would I want to upload a file to you? You need to let people know

I will take that as a compliment! Thank you!
> it can reliably refuse to forward ARP packets for other MACs claiming to be the gateway.

I thought most wireless lans acted as an (shared medium) ethernet, that is, they allow clients to send packets directly client to client? That is, I thought [ed:naughty]-client could just broadcast ARP packets directly to the clients? Or does perhaps (ethernet) broadcast traffic go through the gateway?

None of this helps with a rouge AP, of course -- so it might be a bit academic.

It's insightful and polite. Please control your down-voting, people!
Or "I'm making an educated guess". Otherwise how can you get truly surprised when things turn out to be different in the real world :-)

I'd also guess it would be more expensive during decoding.
So let's compare that with some real data:

https://github.com/eishay/jvm-serializers/wiki
(old wiki but with some graphs https://code.google.com/p/thrift-protobuf-compare/wiki/Bench...)

it turns out that state of the art JSON serialisers aren't so bad after all, especially the serialisation.
What benefit do tighter spreads and faster response times provide to ordinary investors, like me with my retirement fund? I understand how they benefit the market makers; you've explained that. But all that really determines is who takes losses when an exogenous event that affects the underlying fundamentals of a stock gets reflected in its price. That's a zero-sum exchange: the market maker's loss is the predator's gain. How does all this create value on net?
Sorry to hear that. I have heard that in big companies resumes are filtered via keywords. Since, your resume is non-keyword based, you are not getting the opportunity which you deserve.
Both cute and interesting.

Note, however, that the article does not distinguish between what the sign is called, and how it is read. I call it an "at sign". I read it "at". Now, in Dutch it's called a monkey tail (said in Dutch, of course). But that may not be how it is read in Dutch.
The question I have is, how do we get government to hire teams like this in the first place?
Freelance and stay on Github as others suggested. Also its a good idea to get into some local user groups which can lead to job opportunities in the future.
Lol. Not quite accurate but a fair criticism. Note that in the US after the GFC there were deficit spending to stimulate the economy that helped create the Tea Party. In Europe there were instead austerity measures which helped to radicalize the population with a surge in right wing politics. In 2014 the US economy is growing, deficits are falling and the Tea Party is fading. In Europe sadly the economy is stalling and the risks of political unrest increasing leading to unique measures like the one in the article. It was sad to see the Europeans make these mistakes given what history has taught us.
We’ve got your back
>Basically, people fortunate enough to be born with the aptitude for higher education get a 50% premium for their efforts.

I think a minor edit makes this statement more accurate:

Basically, people who complete higher education get a 50% premium on their efforts in aggregate.

Though as others have noted before, this level of analysis is in and of itself problematic. If top performers for multiple generations have entered the higher education system, it is difficult to separate out the confounded variables of natural ability, drive, and the "higher education premium" (so to speak).

How do we necessarily know that college graduates are earning more due to their education, and not because the population of the most driven and/or most able individuals happens to go to college? It's a difficult problem.

The only real viable suggestion I've heard is to compare earnings of individuals with similar pre-college academic performance who attended college to those who didn't. Most likely, these individuals would have to be on the threshold of collegiate entrance (by SAT, GPA, etc.), so perhaps even this analysis would not properly assess the benefit of college to high performing students.

I'm more concerned about the fact that everyone seems to give priority to speedtest traffic, then abruptly chokes streaming HD.

I'd really like Netflix to offer their own speedtest site that looks to the network almost exactly like streaming video, so the ISPs couldn't game the measurements.
Yeah, likewise. On speedtest.net I'm 57 down, 38 up.
So cool! Just got my ticket.
To the best of my knowledge, Net Neutrality doesn't apply to wireless networks.
I didn't say that they didn't provide liquidity; I said that I am not sure that the additional liquidity they provide actually matters to anyone other than high speed traders.
I don't see how "standard JSON" could be any easier when it's even less structured.
No, its not an argument against hiring foreign workers. It is an argument that the current system is broken. I would prefer they do a very ungovernment thing and scrap it then replace it (without a gap / carrying over the workers) with something rethought.

I would particularly be happier with something based on automatic worker visas for graduates of US universities, applying the permit to the spouse also, and no specific company assignment. This sponsored stuff keeps everyones wages down by not providing H-1B movement.
It is so odd to me that the second highest budget outlay is for a system "known as healthcare" for which, I receive none, unless I pay for insurance, which also doesn't pay for anything - rather they require I pay. This same system lost 272 billion to fraud last year.

Rather than clean up the fraud and corruption - we are getting a website?!?, and fines if we don't pay an insurance company to take our money and provide no benefits.

America doesn't have a health care system it has an illness system whence you become ill they are allowed to relieve you of all of your assets and leave you to die.

Protothreads
Ah that might work too indeed, tried doing a homebrew update and that did not work, so fixed it like this and that worked too :-)
If you can't get professional to record the event, just launch a Google Hangout broadcast on the speaker's computer so the sldie is recorded, add a microphone to him/her under $20 and you good to go. If the speaker is close to the computer just use the built-in microphone.
But they also provide a level of security that nothing else can offer for that currency. They literally can print more money if they don't have enough to pay you back.
If Netflix closed its doors today, presumably Amazon Prime and Hulu would pick up the slack. The problem is not Netflix providing content; the problem is users consuming it. Users want better service than the ISPs are inclined to provide.
It's not hard, it just requires honesty and integrity.

Check's already cashed, right?
My current understanding of the Ethereum Project is that they have combined blockchain technology with a programming language to create a platform. This allows new applications to be built storing all kinds of transactions in a trustless & decentralized peer-to-peer manner.

1) Ethereum uses the blockchain technology as a way to decentralize any kind of transaction not just a currency transaction. With the Ethereum platform scripts can be written to automate rules & outcomes which affects transactions on the blockchain.

2) Currently the possibilities are still being revealed. It's akin to asking 'what are the possibilities of the Web' back in the 90's. Current ideas such as reputation systems, peer-to-peer file sharing, domain name registration are just the surface. All of the proposed applications will continue to be built upon over time revealing new possibilities with every application that is created.

3) Currently Ethereum has a proof of concept client & ideas for the core applications. Currently the average user is used to dealing with companies that are the controlling entity for a service they provide. Users may need to reconsider their data privacy & the organisations they do business with.

Do they continue rely on the current government to count election votes fairly or do they support a decentralised version. Do they continue to store their documents in Dropbox where the organisation has total control - or use a peer-to-peer version.

Users may start to use these new applications before they have an understanding of the blockchain. Does this new protocol also mean decentralised responsibility? Perhaps the average user becomes more proactive because a collected effort is needed to keep systems healthy (think of how much torrents rely upon their comments/ratings)

Even further into the future it may result in the 'honest web' where to undertake any kind of transaction online you need to first prove you are trustworthy through your reputation score which is based on your previous actions online.

(I just realised how hard it is to describe Ethereum without mentioning protocols, smart contracts & autonomous agents)
That's not the bank's problem, though, it would be the ECB's problem if banks decided to hoard.
GPGMail might be excellent for you, but it do not support my system. Why are you complaining that FSF have chosen to write a guide that works on any operative system, rather than a guide exclusive to one? If the goal is to "fight for computer user's rights, and promote the development of free (as in freedom) software like GnuPG", then writing about a OS X only program does not sound consistent with their goals.

Apple mail also already support encrypting and signing mail (https://support.apple.com/kb/PH11790). In the interest of defeating the surveillance state, one might start by fixing mail programs that do not already natively support encryption?
Ask HN: Looking for examples of html5 apps that feel native
Looking for examples of both Android and iOS apps that are built with html5 (or hybrid native/html5) but feel completely like a native app.
Yeah, even at the fundamental level, there are fudge factors that vary from year to year and can only be worked out by astronomical observation.

Just measuring what is meant by 'year' is a tricky problem: https://en.wikipedia.org/wiki/Year#Sidereal.2C_tropical.2C_a...
I have not seen that to be the case. As a software developer in the HFT trade I make about the same as I would working for google. If the firms I work for take off or have particularly good years, I might make a lot more than the google salary bands, but it would be about the same as if I were an early employee (but not founder).

Now if you are talking about ibank traders who HFT are replacing, that is true. Their salary bands are enormously higher than engineer pay scales. Sort of explains why they direct so much vitriol towards HFT.
Saying CASL applies to any message accessed in Canada is meaningless. Canadian law can't be applied to foreign entities. Reminds me of what happened with the national do-not-call list.
Same for the quite advanced Alesis IO dock.
But -- it's interesting in a rather different way.

BTW, I once decided that the smallest uninteresting number is 34.

Alas, I don't recall my exact reasoning.
Definitely the right direction for performance. My company ended up going with python-gevent and zeromq to implement an asynchronous API server with persistent TCP connections. Our application servers are able make remote calls over a persistent tcp connection without any noticeable overhead. You could still use JSON, and we tried it--but since we're all python anyway we decided to just pickle the objects which is way faster. We looked at protocol buffers, but found it to be a bit cumbersome. It's been stable for two years and completely solved our scaling problems.
One obvious benefit of "incessant trading of stocks" is that buy-and-hold investors can move in and out of a position for much less than they could in the 80s. The "incessant trading" reduces costs, which can be very important even to value investors when there is some extrinsic prompt to trading.
Saving is hard
Why is this using Amazon servers? Wouldn't it make more sense to use purpose-built machines for this?
"tons of money" is also relative. HFT firms make way less money than the ibanks that act as middle men to most investors and the exchanges.

Most of the money in HFT actually comes from those previously more rapacious middlemen's bonus.
Moving from being a investment strategist to a startup founder next week, here are the thoughts on all of this sent to clients earlier..

"As widely expected the ECB has moved to negative deposit rates in the latest attempt to look useful.

We haven’t seen this happen in many places, but aside from Switzerland, which is always a bit odd, one of the more interesting instances was Denmark back in 2010 when the DKK peg to the Euro was under pressure as investors bailed on the EU. The result of this move was telling, in that rather than forcing the banks to lend more to mobilise reserves, Danish banks took a kicking on margin expansion and lending collapsed even as deposit flight occurred. It did stabilise the DKK exchange rate though, allowing it to depreciate gently.

I think a similar motive is behind this move, primarily to help out Germany where disinflation is very much in place and the surprising strength of the Euro, which I noted last year was due to its assumption of old-Yen like qualities, particularly at a time of taper tantrums, is starting to drag on exports.

It will be interesting to see what happens here even as Spain and Ireland enjoy their ability to borrow money even more cheaply than the US (really, check the 5 year). My feeling is that it will be difficult to actually devalue the Euro significant from here, particularly as the Eurozone as a whole has moved into an export surplus as peripheral deficits have collapsed on falling demand, offsetting the German surplus handily. A fall in the recently recovering M3 is also likely and the lower-for-much-longer policy of the ECB will look particularly attractive on the fixed income side for those wondering if the recent rally in US bond yields is likely to reverse - duration in bunds looks less painful than in US govvies. Money market funds also look quite weird in this environment, with 800bn Euros or so in these vehicles about to break the buck with German 2yr paper still positive.. For now..

As such, I think the Euro may well continue to strengthen after a bit more downside, thus weakening the dollar, EU bank lending will roll over further along with margins and economic malaise is likely to filter into Germany as macroeconomic imbalances extend and disinflation continues, particularly if my negative view on energy prices is correct."
Poll: Have you had your credit or debit card info stolen?
Reading through the comments at https://news.ycombinator.com/item?id=7847047 (the recent Krebs carding story) I was surprised at how many people mentioned not only having their details stolen but having it done quite recently. I would expect that users of HN are at least slightly more secure on average with their sensitive information (like credit card info) than the average person. I thought it might be interesting to see what the prevalence is among readers here.<p>Poll: Have you had your credit or debit card info stolen?

At the earlier 2000's my ISP sent a "drivers" with malware that would disable brigding and NATing at the OS.

But, of course, it only run on Windows, and I was lying telling that I had Windows, as every ISP would refuse to serve somebody that uses Linux...
Vanguard, the world's biggest mutual fund, notes that their costs have gone down since HFT has come into play.

This is an absolutely baffling comment. Particularly for a community (hackers) that value openness and transparency above pretty much all else. What in the world are you talking about, to a general public audience, that can't be heard by the rest of the world?
These people [1] have shown that you can store $1M inside a microwave with room to spare. $100M fits on a shipping pallet.

No doubt that physical money storage has associated costs. -0.1%/yr isn't enough to get someone to start storing money, but -1%/yr probably is.

I disagree. The MFi program is specifically for headphones, not other accessories.

Take a look at the bottom of your iPhone (if you've got one). The headphone port is significantly taller than the lightning port. At some point, even if it's not this upcoming generation, the devices will be too thin to support a headphone jack.

I imagine the next line of MacBooks shipping with lightning ports onboard. Possibly even to replace USB (along with adapters) - USB is the tallest port on the recent units.
Hi! This is the Market Economics Fairy! I would like to respond to whatever it is you're thinking, but I honestly don't know what exactly you're thinking! Increasing the supply of something almost always makes the price go down relative to what it would be otherwise! But then more trades take place too, so more gains from trade are generated, which is wonderful! More people getting paid high programmer salaries can increase the average per-person salary across the whole economy, even if it means the price per programmer goes down! So it's totally consistent for an altruist who wants more people to be paid more to try to introduce more people to programming jobs! The same with decreasing unemployment across the whole economy and increasing unemployment among programmers! But I don't know if that's the part you were confused about! Sincerely, the Market Economics Fairy!
Build a federal gov run IT branch that isn't the NSA instead of contracting things like this out?
It's incredibly difficult. When government money is involved the good old boy network swings into action. Contractors are picked based on political connections first and actual capabilities second.
It's not about conformity, it's about quality. His website at http://resume.patrickcurl.com/ is buggy and doesn't have a consistent look, feel, or writing style. Seeing as building websites for people is the work he wants to be doing, that's a pretty objective kind of metric to look at.
Well I think we should introduce a tax on commuters because as it turns out they are the 90% of the highway traffic.If they want to get to work on time they can use the fast lane for a little extra and if they don't pay we just make them drive 10 miles per hour. I think this is fair. Ohh btw. if they complain about it, it is just them trying to influence policy that was set by good corporations so I don't understand why we should change it. :)

In Canada the second largest group by religion is "no religious affiliation" http://globalnews.ca/news/544591/the-second-largest-religiou...

In BC over 35% are non-religious. In Vancouver it's over 41% with only 5,000 more Christians than "non-religious". http://www12.statcan.gc.ca/nhs-enm/2011/dp-pd/prof/details/p...
Sure, there are limits to foreign jurisdiction. IANAL, but if you have customers in Canada and you also send email to Canada you may have to care about CASL. Even if the message originates from a US server.
