There is nothing wrong with the voltage (110vAC), the issue is power... and to achieve a given power amount (70W typically for laptops), lower voltage requires higher current. See my comment under the 12vDC lighter plug suggestion http://news.ycombinator.com/item?id=1828197.

36vDC would have similar weight problems and, in addition, would require everybody to buy and haul around Yet Another Power Brick since it is oddball.

If they really don't post, then what do they do when they find bugs? fix it and keep it to themselves?

...and this is why I created an alt account, so I could answer honestly.

I would cheat on him. I was dating two other guys when we met, and we agreed when we became serious that our relationship would be exclusive. It was worth it to me. However, I'm not terribly good at resisting temptation.

Add to the fire that my type (surprise!) is geeky males, and there's no way I could resist. A Y combinator class for me would be like tempting an Ethiopian to a buffet.

He's absolutely right; it would destroy our marriage. Some things are more important than funding.

"Snatch of Sliphorn Jazz"
I share your sentiment but I don't think a few links that do well on HN seriously represent the "industry."

HN is more a talking shop for founders and hackers than a public showcase for the Internet's latest and greatest apps. A lot of what goes on here does migrate to the public sphere, but there's no reason to curb the injokes or "fads" to maintain an image on an industry-focused site.
The CPU intensive part of a HTTPS connection is the initial key negotiation/session setup (using asymmetric encryption methods). The symmetric encryption of the actual traffic is pretty trivial.

You can amortise the session setup cost by ensuring the HTTPS session caching is enabled on your server (in Apache, the directive is SSLSessionCache). This will let subsequent connections from the same client re-use the same SSL session.

Upvoted for the idea of finding students - but I wish people would stop with this idea that it's fine to ask artists to work for free while they build a portfolio/resume. It's one thing for an established artist to get assistants like that, because they're rewarding them in other ways. For anyone else to do so is degrading.

Also stupid, because without payment you will have no way to assert ownership of the design/logo/etc. later if you get sued for copyright abuse, by the artist or an assignee.

That depends on what kind of business (or ways to make money) we're talking about here.

For example, there are many web startups and web consulting companies that use typical LAMP stack or "light-weight" Java stack (Spring -IoC,AOP,MVC-, Hibernate/iBatis, Ant/Mavent, Hudson, MySQL/PostgreSQL).

There are also other types of work that would require heavy help from the open source tools. One such example is embedded development. My friend works at Broadcom and he uses gcc, vim, ctags on day to day base. I'm sure companies that operate in hardware, system, and, network fields are also using open source tools heavily.

The Russian developer, who used to work at Goldman Sach and got caught sending his work to some server, used a mix of Erlang, C++, and various other tools as well so I'm guessing those big guns at Wall Streets are using open source tools for their HF trading systems.

Then there are your typical insurance companies, your typical hospitals, your typical small businesses, your typical banks, your typical grocery stores that would swear by Microsoft technology for their internal apps.

I'm not trying to say that Microsoft is not suitable for "serious businesses". I'm looking at the trend around me and it seems that Microsoft technology appears in places where people need something quick to be done and would never add major features, instead just bug fixes and small polish here and there.
One of the big benefits of using virtualenv is that you can change the environment your code is running within. For example, if I want to test a new version of a package (or a new version of python altogether), I can create another virtual environment and "workon [newenvname]", ./manage.py runserver..., and test away.

It also follows the principal of least surprise. As a developer, if I run a python file, I generally expect it to use the python version in my environment, not some hard coded path. This is exactly why manage.py references python in the environment (/usr/bin/_env_) and not a direct path to the python executable.

It's easy to switch virtual environments and unexpected that I'd have to change code.

I could be wrong.
Right, and even the paid ones can be had for well under $30/yr nowadays, which is pretty trivial.
It depends on how secure the remote network is. If it's just another coffee shop, you're screwed. If it's your own Linode in one of those well managed datacenters, it would be pretty difficult for anyone to snoop that traffic.
They already have 400hz power (not sure of the voltage) from the engines.

Why not just use a switching power supply to change that to 60hz 110v? Why this whole business with inverters?

Computer moves always looked unnatural to me, though, and you could often exploit this easily. I'd say most players are at least comforted by lack of computer headway into Go.
Thanks! I really want to get it to the point where it can look into your friends lists to generate lists as well.

For instance -- What're my girlfriends favorite movies that I've never seen? Or What are my friends favorite movies of all time (that I have seen or haven't seen)? In the end it's all about keeping track of what you've seen, and helping decide what you should see next though, so it might have Netflix integration so I don't have to reinvent the recommendation wheel either. What movies you'll like is only half the equation though -- the other half is what people you know are actually watching!
I think this might have something to do with the ineffectiveness issue: http://www.jigsawhealth.com/resources/myth-multi-vitamin

As far as the supposed dangers I find their argument hard to swallow. If the increased chance of breast cancer and prostate cancer was really that high I'd think we'd be seeing massive fallout. Multi-Vitamins are a 4-billion a year industry meaning they're pretty wide spread and have been around for way longer than 10 years. If the female population was truly 19% more likely to get breast cancer it would create an impossible to ignore societal phenomenon.

Don't confuse the art with the artist. Being familiar with context and the tropes of the genre (like braggadocio) are important for understanding white rappers, too. It's the same as with any other lyrical genre of music or any other form of communication with language or any other performance art. Why would it be any different for rapping?

Show HN: My super easy quilt builder
It would still seem to me like it would be context sensitive, in the sense that you want different information to hire different types of professionals and also that people put different aspects of their life online.

To follow on from your example of me - googling projectgus gives you my both my personal blog and my twitter account as the first two results. My twitter account title gives you my real name, and if you google that then you immediately find my current employer, and some details from an old employer, and then a long tail of quasi-related noise.

Whether or not you'll find anything relevant to what you want depends on what you're looking for. I don't have a resume posted online, which means that although I'm a professional programmer most of my programming experience doesn't immediately show up anywhere on the internet.

However, it's possible you could infer a lot of it from my posts on various little mailing lists and forums (for example, a handful of posts on Erlang-Questions because I spent about a year writing Erlang and a few posts on the Hibernate forums because I've done a little bit of Java middleware development.) Maybe.

Of course, nobody just says "let's see if Angus is a hacker we can hire". Someone might say "oh, you need more Erlang programmers? I know a local programmer called Angus who has programmed in Erlang" (for contrived example). In which case, you google my name + Erlang and you can see that I've programmed in Erlang. Although my online Erlang presence is, in my opinion, underwhelming and you would not decide to approach me on that basis. Which, in my opinion, would be a mistake. ;)

However, even though you wouldn't get specific information about me, you would be able to read my blog and find out I like Linux & open source, I own an Arduino, I like taking apart cheap chinese gadgets, and I like writing. Which is possibly all useful information, again depending on exactly what you were after me for in the first place.

Although I didn't put that information online to get jobs (if I did want to do that, I'd have a resume section online or a LinkedIn profile or something, and maybe the above paragraphs of rant would be redundant.)

I hope this discussion helps you in whatever process you decide to automate. I understand that you're talking about something a bit different, but at the same time I think it would be hard to come up with a one-size-fits-all approach that was entirely based on scraping other data. Finding something more specific, in the same vein as Haskellers.com except without the user-submitted data, might be plausible.

Stack Overflow Careers, for instance, uses Stack Overflow as its data source but OTOH it still relies on the user to submit other details, in order to make the information relevant to employers.
hmmm that makes sense, why would she want to do work for free? she is paid to teach paying students and help them improve. my parents are both college professors, and they get paid for online courses based on the # of enrolled students i think.

Quoting from that, "On our production frontend machines, SSL/TLS accounts for less than 1% of the CPU load, less than 10KB of memory per connection and less than 2% of network overhead."

There may also be concerns about insulating the flight electrical system from the cabin electrical system. What if there's a surge or huge load in the cabin? You need to be sure that that sort of thing can't affect the engine operation. The easiest way to be sure is to put an air gap between them.

JQuery 101, Part 1 : Objects and Functions
The CPUC says that limousine service must be pre-arranged, unlike taxi service. I didn't see a definition of "pre-arranged", but UberCab doesn't sound pre-arranged to me. You use it when you want transportation now, not when you know that you have an upcoming need for transportation at some definite future time that you wish to ensure is covered.

Yes, you have to sign up for the service first and get the phone app, but I don't see that this makes a difference. What's pre-arranged there is the ability to use the service. When I turn on my TV, go to the "On Demand" section, pick a movie, and watch it, I doubt anyone would say I'm watching a pre-arranged movie, even though I had to previously subscribe to the cable service in order to do so. Seems to me that's essentially the same as what UberCab is doing.
What are your costs? What is the marginal overhead? What is your customer acquisition cost?
Makes a strong case for everyone to start tunneling their traffic back to a trusted network.

I've been trying out sshutttle <http://github.com/apenwarr/sshuttle>. It only tunnels TCP traffic, so you still have DNS and UDP traffic on the local network.
I used to be a huge fan of Taxi Magic but the past few months have found it less and less reliable. Basically if the cab is over .2 miles away it will pick up a fare on the street instead. When UberCab tells me that a car is coming, I can trust that it will actually come.

Seems like a red herring to me. Taxis aren't by any means the majority of the traffic in SF, so I doubt having more of them would cause a major issue. If anything, it would make things more manageable by easing the parking situation (since prices would be lower and people would not need to drive).
Eh, I just got approached by Google via LinkedIn and went for it even though I was sure I wouldn't get it. Sure enough, I did not get it, but it was nevertheless a valuable experience. I have learned two things:

1) An n^2 algorithm runs in polynomial time, but it is no longer good enough when n ~= 100000000. Assuming 1000000 operations a second, that is still a few hundred years. I have never thought of it because I've just never encountered that sort of scale. I may never do, but it was still a revelation for me.

2) It confirmed that I am really rusty at algorithms due to one too many jobs writing CRUD web apps. I need to do something about this. For a start, practice in my free time and secondly, look for a job that allows me to develop in that area.

I'm not saying that it wasn't disappointing even though I knew my chances weren't good, but I gave it my best shot and I am choosing to use the experience positively. Is that serendipity?
Ah right, sorry.

I found the binary "firesheep-backend" in:

~/Library/Application Support/Firefox/Profiles/<profile>.default/extensions/firesheep@codebutler.com/platform/Darwin_x86-gcc3

I ran both:

./firesheep-backend --fix-permissions

and

sudo ./firesheep-backend --fix-permissions

and it still asks me to run it with "--fix-permissions". I guess it's time to go digging around in the source to try and find out what it wants me to do.

EDIT:

After a bit of digging, I found out that running it with --fix-permissions really just chowns the binary to root then setuid's it. I don't see anything wrong with it on the surface, but I'll keep digging.
They will, but are they skirting the law in doing so?

Neato! Worked snappy for me. Kudos.

Suggestion: It appears that the searches sometimes stacked up in queue if I typed fast. (i.e. if I typed a long sentence quick the results continued to flash different content many times, playing catch-up. Looked through the JS quick and I see you are trying to prevent this with runningRequest1/2 so maybe it's the short delay in the .fadeTo() after the GET callback. Try moving the runningRequest = false into the fadeTo callback.

Also, .fadeTo() has a default queue of it's own.
You could also add .stop() like this:

$('#function').html(data).stop().fadeTo('fast',1);

Otherwise, really cool! I use "site:php.net foobar" most of the time but this would be a great little widget.

Switch-mode power supplies are essentially DC rectifiers, which will never ever give you 110V, 60Hz (an AC voltage).

One way to change the frequency of a power source is through a double-conversion type AC/AC converter, i.e. 1st stage is a rectifier which outputs a DC voltage - this is an arbitrary DC voltage, but it needs to be within the voltage tolerances of the 2nd stage - an inverter, which reconstructs an AC voltage from the DC link to whatever frequency you like.

This setup is also the basis of most UPS systems btw, with a battery connected in the DC link.
Not necessarily. Some sockets can cope with the majority of the AC plugs in Europe and America.
