It's funny that you mention the keyboard shortcuts!

When I talk to old hackers on Linux about moving to OSX, I tell them, "well, if you move, you don't have to configure your power management and display drivers and it has Emacs keybindings in all the windows!" and they get excited.

When I talk to young CS undergraduates --- all of whom have Macs, because it's not an engineering college --- I tell them, "you should learn Emacs; I know it's in a terminal, but it has all of the OSX keybindings you already started to learn!" and they get excited.
And in my experience, OP has it right.

1. Setting up the mail server is not the issue. It's the ongoing maintenance to ensure close to 100% uptime so you don't lose any mail. Having worked as a sysadmin maintaining linux boxes for several companies, mail server maintenance accounted for the vast majority of the hours we spent working on servers. This doesn't even account for the hardware upkeep to keep RAID sets in good shape, tape backups, etc.

2. There is simply no open source project that offers a UI anywhere close to as good as gmail. Yes, someone could take on that project, but it will be years before they achieve a similarly polished result.

3. Sure you could roll your own filtering that would be more effective than gmail's, for you. Again, this is further work that you have to do whereas gmail "just works".

4. SpamAssassin is one of the great open source projects in my opinion. Combined with ClamAV you can get a really robust solution that works fairly well. However (afaik) it lacks the learning heuristics that gmail's huge body of data can provide to keep even the newest template spam out of your inbox.

This is not to say that I don't agree with some of your points, but in my opinion the OP has a valid perspective, which I suspect many IT people who value their own time will share.
I'm currently working on a piece on why Chimpanzee mothers are superior.
So what advantage does a 60-year-old .NET programmer have over a 27-year-old .NET programmer when they both have, at most, 5 years of experience doing .NET programming? Absolutely none.

Regardless of your age, you do not want to work for companies that believe this.
I'm a programmer that does more front-end (html5/js) than back-end, and perhaps 'adequate' design skills (I don't do graphics, but can make decent-looking prototypes with enough css).

When looking at the description for the designer job in the OP, its not the design/technical combination that seems over-the-top, but those two jobs and a third job doing A/B and conversion rate testing. That needs to be delegated to somebody else, either a separate designer, a Quality-Assurance person, or the project lead.
Wow, I thought the illusion that other cultures are simply behind the US instead of genuinely different had all but disappeared. (With the exception of Micheal Arrington of course.)
French parents learned to ignore, say no to their kids from their parents who learned from their parents and so on. In other words - it might be in their culture. I grew up in India and do find a lot of similarities in my upbringing - our egos were not always served, maybe 30% of times. We had family in US and I noticed - kid's egos in their families were served 90% of the times. As mentioned in the article, kids were ruling their life...whereas in my family it was the other way around. Did it make any difference in the lives of those kids or mine - that's a different topic. My point here is maybe American parents were told to over parent. By whom - not sure, but could be babies r us, or mattelle sponsored studies, or ads on TV to promote products, etc.

Cool. But this article was in no way racist or sexist, right?

1. All one-way valves depend on flow. If there is a higher pressure from A to B. And that's the direction of resistance, then in a valve with moving parts, a ball or diaphragm of some sort would be pushed against a lip, and the flow would stop. That still depends on a pressure difference where flow was traveling from some high pressure point to some low pressure point. Let's say that valve was off design for the flow rate. It may not have enough pressure to seal, and it would still be leaky. The Tesla Valve's performance is measured by its diodicity, and it has to be matched to the conditions it's supposed to exist in. If it was really well designed, it's diodicity would be very high and thus leakage would be minimized. From an engineering standpoint it still usually makes sense to use valves with moving parts on your example lox tank. As the main way of checking flow, they are well understood and very reliable. However, if you are in a situation where a moving part is a negative, like in microfluidics, a Tesla valve might make more sense.

2. Liquids and gases have different viscosity, so the Tesla Valve would be different for each fluid and flow regime. I am unfamiliar with this series-of-petals geometry you are remembering. However, it reminds me of this excellent work done on optimizing topology for different Reynolds numbers in Tesla Valves: http://www.senlin41.org/topology-optimization-of-tesla-type-...

3. One of the original intents of the valve was for Tesla's Bladeless Disc Turbine. In Tesla's time, materials were not what they are now, and thus valves with moving parts were not as reliable. Also, getting a valve that can close and open with high frequency is not always easy. The valvular conduit that Tesla designed was his solution to this problem.

Thanks for the book reference. I read "Wizard: The Life and Times of Nikola Tesla" But I hadn't seen this other book. I might pick it up.

LLCs can be pass-through entities or corporations.

EIN application is not a requirement for all company structures. See 'disregarded entities' or single member LLCs. Resident single members can use their SSN instead of an EIN though that's not normally a good idea as it erodes limited liability. In this case, and in the case of a partnership, you are definitely not an employee in the eyes of the IRS.

Any foreign corporation can be a member of an LLC. In a single member configuration the LLC would have zero US filing requirement.
Very neat! I would like to hear more about implementation details. Also what fullsailor pointed out.

How to Release iOS Ad Hoc Builds with Xcode for Beta Testing
I agree that the easy availability of alcohol to teenagers in most European countries seems to achieve the effect that you describe.

There is another angle to this though - is it better to engage in binge drinking right in the middle of adolescence, when the body and mind is at a rapid pace of development, or in your twenties, when you are physically better equipped to deal with the effects of excessive alcohol consumption?

I am not a medical professional, but instinctively, the second option seems to me to be the safer one.
Why i can't make this app
Well my name is arturo, i'm an aeronautical engineer, but most interested in entreprenuership and internet startups.

I recently got acepted to an accelerator in san francisco and i'am about to get 25k in founding; can't say the name. I was trying to develop the app with my techical co-founder, but he's recently acting very strange since we got accepted to the program; he's currently studying computer science, and is in his third year, i have tried to meet up with him but he says every time that he's really busy,and i'm sometimes thinking that he doesn't want to help me anymore, because i think he's too scared of dropout of collenge and leave his family to work in san francisco.
Before i was trying to make this app, like 1 year and a half ago, i was starting an ecommerce webiste; something like p2p commerce with some cool technologies, i had 1 one cofounder that was very helpful at that time and helped me with the idea development, so when we start doing some work i invite him to help me with the development; i have to say that i'm not a coder i have tried and been to java and php courses but i've found that that's not my thing, i love selling the product and business, i think that, that's what i'm really good at.. In fact i meet this person(techical cofounder) in a java course, and beacame friends..

He has accepted to help me with the product but i've seen that he's not very commited to help, he preferes developing apps that adds lol and troll faces to people, i think this doesn't change or help to improve the world.

The company that i'm starting is app,that its really a social magazine for shopping(very interactive, similar to flipboard) i'm not going to say my secret sauce, but i'm really passionate about this, my technical cofounder was going to develop the adroid app and i was trying to search a developer for the iphone, but now that my cofounnder is gone, i have nothing now, i'm really sad, i couldn't try to learn objective c beacuase i haven't a mac right know and i think i will need large amounts of time to learn it, i really don't want to waste this opportunity because of my cofounder.

So if anyone here is interested in help me out with this app please contact me at my e-mail: arturo_g_p@hotmail.com, or here... I could give you some equitity in exchange... You need to be able tomove to san francisco to work in the company within the accelerator program...
Thanks!
Chiming in with more anecdotal evidence. My folks allowed us to (illegally) drink alcohol starting at age 14. It was something we did during special occasions, and we'd of course drink smaller portions due to body size differences. Reaching "drinking" age was no big deal.

Only once in my life have I ever drunk so much I threw up. And that was on my 25th birthday when I got a bit careless.

If "doing pretty well" looks like this on a global scale, we've got some serious issues to resolve.

Of course, I suspect the actual issue is that this is the food industry, which is (as already mentioned) heavily regulated for not entirely unreasonable reasons.
>They should have the freedom to not give back. What GPL does is force developers to release their code.

They only have to release their code if they are using someone else's GPL licenced code. They are totally free not to use GPL licenced code, we can argue the semantics of 'freedom' until the cows come home but nobody is forced to use someone elses GPL licenced code.

>A BSD license benefits the market and end user,

It benefits the proprietary market, and if you want your code to be able to be used in proprietary projects then yes, BSD is indeed a great choice. I don't see how the end user is better served by BSD than GPL.

However, many developers pouring hundreds of hours into code they then release as open source do not have any intention of having that code end up in proprietary projects. They want the code to remain open so that they as end users will be able to recieve any enhacements done to their source code. And given the vast popularity of the GPL licence, particularly for open source applications then I'd say it's serving it's purpose.

And don't take me wrong, I think programmers releasing BSD licenced code are extremely generous, and I personally think BSD/MIT style licenced code is a better choice for single purpose library/framework/component style code where there's little risk of proprietary forks.

At the end of the day GPL is about the source code and any further enhancements to it being made available to recipients, and this is what has made it so popular. And while that means it can't be used by proprietary code projects, we have ample proof that it's a licence through which lots of companies chose to cooperatively develop open source code, likely due to the very fact that all distributors of that source code is legally bound to release any enhancements.

I have done lots of experiments with 3D versions of this valve. I even did some with a traveling rotation along the axis, so that it looked like a helix. Unfortunately, those were duds, though the looked beautiful.

My current jet engine work does not include a Tesla Valve, though much of it is inspired by it. When I began, I imagined using a pulse jet, and attaching an axialy rotated tesla valve to the front of it, in order to replace the reed valves. I eventually moved away from pulsed combustion though. Too noisy and not the pressure levels I wanted.
By far the best work on this subject has been written by Lawrence Rosen in his book "Open Source Licensing":

http://www.rosenlaw.com/oslbook.htm

Free to read online - or buy a hardcopy.

Unlike less useful works, Rosen actually provides a model for thinking about open source models. Even if you only care about commercial software licensing, this this information in this book will be valuable.
That's a good idea. I've seen some of the wave generator concepts out there, and everyone seems to be trying different concepts for harnessing those oscillations. No one has it nailed down yet. One of the most intriguing mechanisms I've seen is this oscillating submersible wing: http://liquidr.com/technology/wave-glider-concept/
Hmmm. Well, my strong negative reaction to it started with the last three words in the title.

Note how different "I haven’t been drunk in 3 years... and I’ve been partying way more than you" comes across, when compared to something like "I haven’t been drunk in 3 years… and I’ve been partying a ton!"

As soon as you mention "more than you", you're making a direct comparison of your behavior to your readers' behavior, and that not only comes across as judgmental, it invites criticism from anyone who behaves differently and prefers it. (Like, for instance, me - I enjoy a quality beer or wine, but for me your social life, drunk or sober, would be the ninth circle of hell.)
It is very hard to give numbers. But I think it is hard to argue direction though. If there was a no-poaching agreement in place amongst a "cartel", would salaries of the employees of the cartel be higher than normal? Certainly not. They could be the same (assuming there is a sufficiently large number of non-cartel employers) or lower.

This sort of argument is often made in Economics, and is logically sound. Ceteris Paribus aka everything else being the same.

I agree the article smells of link-bait. I don't understand why Facebook's IPO is different from every other IPO that has happened in the past. Why does the author feel that this IPO will raise wages of developers in the valley?
As much as I love Tesla, if this is true - he has failed :(
> your twenties, when you are physically better equipped to deal with the effects of excessive alcohol consumption?

Why would you believe that? I don't have any specific knowledge, but I also see no reason to believe that you're better equipped (physiologically) at 25 to handle alcohol than you are at 15.
Perhaps your local Apple Store doesn't check for unlocks before warranty replacement, but unauthorized unlocking absolutely voids your warranty in principle and Apple would be well within their rights to refuse service. If you don't believe me here's the relevant section of the warranty (written by Apple in bold):

"This warranty does not apply: [...] to an Apple Product that has been modified to alter functionality or capability without the written permission of Apple".
It's more underhanded than nasty but you're absolutely right that this didn't mean what they portray and most people thought.

Regardless of whether a given user moderated his data usage voluntarily, because he was throttled, or switched plans, the vast majority of the top 5% likely leaves the pool every month. This means that six months after the change was introduced roughly one quarter subscribers will be removed.

Why would AT&T do this? To avoid the negative publicity associated with eliminating a plan so many people valued while maximizing profitability. This was quite cleverly executed: Offer cheaper limited plans to save customers money, which has the effect of offering new customers a more competitive price while existing customers will happily pay the higher price as insurance against potential overage fees. Then, by removing the highest data users, they could maximize revenue from them while continuing to collect the higher fees from the lower data users. Then once unlimited becomes a less attractive offer than the $25 plan, eliminate it to avoid revenue leakage. The strategy might not be optimal but its superior to the simpler alternatives in the short run.

Of course, the reason is works is that the majority of customers are sufficiently credulous to purchase an implicit insurance contract that AT&T never had to honor. Their actions are legally defensible since the customers did receive the uncertainty reduction in the present period but most of them likely knew they wouldn't go over and paid only for the option of maintaining that protection in a future period. That said, communication that is intentionally ambiguous so as to benefit from misunderstanding should constitute an unfair trade practice.

Yeah, picking one metric might be extreme. The point is to discard the bullshit ones.
I think that yo should start with C,many of the programming courses in both universities and highschools try to teach this programming language first, mainly because is very easy to read and understand... After learning the basics you could start with some ruby on rails beacuase you could be able to develop powerful applcations in less time...
Good luck! ;)
Ask HN: SurfScore incentivizes user conversion, what do you think?
SurfScore uses achievements to motivate users to try out all of your sites best features, as opposed to just getting them in the door with ads. We believe that activity-based advertising is the direction advertising will inevitably have to take to remain relevant as younger generations become desensitized to traditional ads.

We work with companies to implement a series of achievements (kind of like a "quest line") that the user can complete over a period of time, which walks them through all the best features of the site, hopefully increasing its overall attractiveness to the user. Completing the various achievements earns them SurfScore, which can be combined with any SurfScore earned elsewhere in the SurfScore MarketPlace, which is maintained by us. The idea is to bring them in with the points, and then let the best parts of your website keep them coming back later.

We've definitely got a chicken-and-egg problem, which is why we've started with integrated quest lines on familiar websites Facebook, YouTube, and Twitter, as well as featuring daily achievements to keep people coming back. We're hoping to get some feedback on the UI, as well as how this sounds as an alternative to traditional ads.

I'm not sure about that. Google Music's sync client is horrendous, as were Google Desktop and Gmail Notifier. I wouldn't trust Google to be able to make a client on par with that of Dropbox. (Remember, Dropbox engineers actually reverse engineered the Finder and performed code injection in early versions to get the user experience they wanted.)

A singular devotion to UX is not something that can be duplicated given "the right amount of engineering resources". (jrockway's thinking is totally emblematic of Google and Microsoft.) It requires the right, most product-focused people in charge.

My late-night reading currently consists of the book "Wizard: The Life and Times of Nikola Tesla; Biography of a Genius" by Marc J. Seifer. For anyone looking to learn more about the man, this seems to be the most comprehensive biography available. While only half through it so far, it's been an enjoyable and enlightening read.

The author's occasional dry humour is also quite welcome. Here's a sample:
"Due to his meager funds and general inability to budget himself, Tesla had but one suit, which had withered from use. It was the time of a religious festival, and Szigeti inquired what Tesla would be wearing. Stuck for an answer, the youthful inventor came upon the clever idea of turning his suit inside out, planning thereby to show up with a seemingly new set of clothes. All night was spent tailoring and ironing. But when one starts with a wrong premise, no amount of patching can right the problem. The outfit looked ridiculous, and Tesla stayed home instead."
Would that be my personal email account, my gmail account, my other gmail account, my university/alumni address, my work email or the other work email?
