> To carry a load of 22amps 20 feet with a voltage drop of <2% with a 12V system requires 4awg wire.

The wire size needed to carry a load of a specific number of amps does not vary with the voltage between that wire and some other wire somewhere. Perhaps you mean, "To carry a load equivalent to 22 amps on 120 volts, a 12-volt system needs to carry 220 amps, which requires 4AWG wire to lose less than 2% over 20 feet."

Yet another cautionary tale about email. If you read the actual motion here: http://www.scribd.com/doc/61754518/11-08-05-Oracle-Google-Jo... you will see that part of the argument is that 'auto-saves' of an email are at question here, in part because the To: line hasn't been filled in (to one of Google's lawyers) and of course the email doesn't contain the 'propietary and privledged email' clause that every lawyer has a part of their .signature file these days.

When you look at behind the covers on the Oracle case, and you read the various 'your a meany' emails that have come out recently over patents and buying patents etc. You can really appreciate just how "young" Google as a company really is. I don't know if this will change whether or not the appreciate just how valuable folks like Brian Reid [1]would have been to keep around, but it will change permanently change the leadership forever.

So...rather than focus on the substance of the post and say something intelligent about a serious subject matter you choose to critique style.

What if I actually wanted to SHOUT?

And, on top of that, you down-vote me for style without knowing my intent rather than on the substance of the post, which is what the voting is supposed to be about.

Have a good one pal.
Some of the most rewarding courses I took during my time in college were writing courses, in both fiction and poetry. Definitely, it helped refine my grammar and composition skills.

But the creative writing courses really provided a lot of other valuable experience too. Having to put together a creative work involves parts of my brain I never really used while coding -- it was sort of a challenge to put aside the methodical, linear path I live in while programming and have to imagine a world, then put someone in it, and have them do things that people might want to know about.

The other nice thing about workshop-based writing courses is that you generally read and comment on works written by your fellow students. You learn new craft skills from reading their work for sure, but you also learn how to give constructive criticism where it needs to be given.

This sort of diplomacy is something you need to practice in order to be good at it. It will help you later when you're in a code review meeting at work and you are the guy who can step up and say something more useful than "you're doing it all wrong, that code sucks, and so do you."
True, but in the special case where your search string is composed entirely of 7-bit ASCII characters (the characters representable as 1-byte in UTF-8), like the example, shouldn't the character-equivalence logic still be easy?
The LED technology used in that bulb seems a little dated. I believe it's using Phillips' Luxeon Rebel LEDs.

Looking at the pictures, there's 3 sections and each section has 6 Rebel LEDs. Total of 18 LEDs. All for output of 800 lumens.

A recent LED flashlight can produce 800 lumens with just 1 (CREE XM-L) LED. For example, http://www.fenixlight.com/viewproduct.asp?id=141 If you want a warmer white tint, it's a little less lumens, but you can always use 2 LEDs..

LEDs have come a long way in the last couple of years. It's just unfortunate that light bulb manufacturers do not make and sell new models as quickly as flashlight companies. There seems to be a new model every week with the latest LED for crazy light output.

Another example, http://www.fenixlight.com/viewproduct.asp?id=149 It does over 2,000 lumens with 3 LEDs!! This is just one company. There are many more that also have crazy flashlights.

If you want to learn more about LEDs or flashlights, head over to http://www.candlepowerforums.com/vb/forum.php

WHS was a great idea tied to an awful implementation. I installed a copy through MAPS at work, and I think it lasted all of 15 minutes before I dismissed it entirely; it looked like very little more than Windows Server 2003 with some weakly integrated automation sitting on top.
Anyone know what this comment means:

Incandescent technology is still superior to any other lighting tech, especially solid state. When one factors in laser sintering of incandescent filaments that increases their efficacy to 3-5 times even LED's, incandescents absolutely rule when considering their performance and cost of production/recycling/logistics/..ect... I love bandgap technology, but it will be hard pressed to beat Edison's brilliance (it hasn't been done yet, despite articles such as this one).

QuakeCon 2011 - John Carmack Keynote Q&A
While that has been true for 70 years, it is ceasing to be true now; today you can often make your program faster by causing it to do more computation in order to avoid communication, or in order to tolerate communication latency, which may involve doing more communication, or occasionally in order to tolerate node failures, so that you can take advantage of more nodes.
Absolutely. I don't quite understand this seemingly common held belief on HN that first-in somehow means you own an idea?

If we want to save the economy it starts by congress realizing they allocate capital poorly and should stop doing it.

"One element would be a program to forgive student loans and debt for young entrepreneurs, which he says would address a major hindrance to recent graduates who want to set up their own shop."

This is silly, either everyone owes their debts, or they don't. It's tantamount to pushing your student loan debt onto everyone else and reducing the risk that the lendee has by spreading it to everyone else. If you want to have the reward of starting a business then you need to take the risk, otherwise society should also get the profits from the business. (eg. when you sign the document saying your loans are forgiven then the people get 90% of their company because they are taking all the risk).

The idea that a Harvard grad should be bailed out by a person making minimum wage so they can be risk free enough to start a business is ludicrous. If someone was so stupid to agree to take on debts that can't be bankrupted to the degree that they can't rent servers for free from Amazon, Google, Microsoft, et al, then they deserve what they got coming to them. Bailing these people out at 22 will lead to the next generation of too big to fail companies that can't manage a balance sheet, nor understand the different types of debt and the legal obligations that come with them.
Ahhh thanks!
Don't have the iMac anymore, but what made matters worse was that I switched Control and Command to make more of my shortcuts work. Command+C or Command+V isn't a very natural finger movement on the Mac keyboard I had. Ctrl+V fits much better and matched up many more (Windows) keyboard shortcuts.

But it made shortcut listings more confusing, because that would become Ctrl+← and Ctrl+→ (which I'm pretty sure I tried in Terminal but would always skip to the end of the command line, not the end of the screen line). The only keyboard shortcut that hurt after switching command and ctrl was in chrome. Chrome's History is Ctrl+H on windows, but Command-Y on mac, due to Command+H hiding the current window. That got me every time.

Unfortunately this implied "downgrade = stock plunge" association seems to be everywhere this morning with no mention that long term interest rates for US debt have actually dropped.

Well, if everyone believes that downgrade --> stock plunge, or even if a sufficient number of people believe that downgrade --> stock plunge, then it's no surprise that downgrade --> stock plunge.

I think the smart money will be hunting bargains. Pity I don't have any right now.

Ask HN: Non-tech startups?
Hey HN,

I'm looking for news sites/blogs that cover non-tech startups. I hardly hear about startups that aren't tech related, and I wanted to expand what I read and see the innovation going on in other parts of the industry. Please share any good sources of information for non-tech startups!
I used to have a crossover cable which is basically a single ethernet cable where the two connectors are reversed. You eliminate a switch / hub and it is a ridiculously fast way to transfer between two machines.
I've tried that, and I have a few issues with it:

* For good ergonomics you need to align the top of the screen with your eye level. I couldn't figure out a way to make this happen, so I always had one non-ergonomic aspect.

* Making big saccades (window-to-window) is easier for me when the windows are side-by-side than top-to-bottom. Windows 7's dock-to-edge feature is really convenient, and I don't know of a good alternative for vertical arrangement of windows.

* As someone else points out, the screen is unwieldy to rotate.
I keep seeing this argument on threads about interview questions.

The principle of not reinventing the wheel has nothing to do with interview questions. Sure, if you're actually working on solving an actual problem at your job, then most of the time you'll be better off using a standard library function instead of rolling your own.

In the context of the job interview, however, it doesn't matter if the solution to the problem is well-known or whether it can be found in a standard library. The problem of the interviewer is not to find out how to compare strings, it's determining if the candidate will be able to write proper code if hired. And the string-compare question might be a good starting point for evaluating the candidate's level. In any case, the fact that a solution is in a standard library is irrelevant.

If I was the interviewer I'd create a new data structure Foo and then ask the candidate to implement Foo.compare(). The question remains essentially the same, so I wonder what the candidate would reply.
Good karma!

Back in the days of pay phones, I had a friend who'd put quarters in the return slot. While it is a very small gesture, it moved me. Felt like sharing this.

"Deep discounting and coupons are counter-cyclical"

Not if they're mostly (or even significantly) in discretionary categories and experiences, though. You could offer me 90% off a tennis lesson, or 99% off a trial run of Invisalign braces, but if I'm struggling to make ends meet on the basics, such offers are of little use to me.

In fairness, I have no idea what percentage of Groupon's offers are discretionary. (Though, anecdotally, it sure seems like a big number). But my point is that I wouldn't put it past many analysts to assume that it's a significant percentage. And that's all you need to move the price of the stock.
Not in cahoots at all, it really is a very interesting book. One of the most...different, I guess is the word, math/physics books I've read in quite a while.

Be warned, it might not be the best book for beginners, and in all honesty it's more a math book than a physics one, but if you feel at least somewhat math-competent, it's worth a read. At least I enjoyed it a lot.
I wouldn't discount the effect of the S&P downgrade on these stocks. The downgrade led investors to flee from risky assets to more secure assets. Counterintuitively, this is causing the price of short-term Treasuries to go up, since they are still viewed as relatively safe investments and constitute one of the largest and most liquid bond markets in the world. The S&P downgrade puts more pressure on the U.S. government to raise taxes and/or take austerity measures in the near future, and that partially accounts for the plummeting price in stocks today, with the riskiest stocks taking the biggest hit.
Hyperinflation will start

I bet you a trillion dollars that it won't.
These are not simple questions. If you are a journalist, follow the money. I personally suspect that the offensive use of patents, both by "trolls" such as Lodsys and large players such as Microsoft, has stepped on enough toes to cause certain vested interests to start a broad-spectrum fight against other vested interests. One usual result of those kinds of fights is manipulation of the public sphere, also known as "press relations".

A Graphic Novel Biography of Feynman
I've thought for a while that we need to switch to multicolumn views for web browsing:

http://lists.canonical.org/pipermail/kragen-tol/2006-Novembe..., "multicolumn web browsers":

> So the solution generally adopted --- in newspapers, dictionaries, and research papers --- is to lay out the text in multiple columns.

> With Apple's 30-inch-diagonal 100dpi display widely available and
> multiple-screen solutions becoming common, it's well past time to
> adopt this solution for web browsers as well.

http://lists.canonical.org/pipermail/kragen-tol/2000-August/..., "Phone browsers suck":

> On the other front, ever-growing screens on PCs present the opposite problem --- how to usefully use a screen the size of two sheets of A4 paper side by side? Interface idioms that worked well on smaller screens --- a menubar along the top, single-column text filling the screen, icons sized by pixels --- become clumsy.

I agree that moving tabs to the left side of the screen is a good idea, too. --enable-vertical-tabs doesn't seem to work for me in Chromium. Tree Style Tabs in Firefox gives you both tabs on the left and tab groups.
I think mariusmg is making a point. The text above is written as if the person solely did the work. In my opinion it would have been better to write it as "part of numerous teams, including ones that developed X, Y and Z."
How I hacked an android game with Python and OCR
Oh man, this is perfect. It comes out August 30th, so you have to preorder.
I'll take on your first question. In large part for me, the implications of software patents are becoming an increasingly clear obstacle to individual developers. We're not talking patents for incredibly complex processes and lawsuits aimed at specific, large companies. Instead, we're facing lawsuits over (arguably) trivial/common features of an app. These can have a very direct negative impact to the individuals that frequent HN.
My thoughts exactly. It depends on the room; yellow in living/dining, and white in bathroom/office.

I have a white CFL desklamp in my home office, and by a chair in the corner I have a yellow corner lamp (admittedly incandescent not LED).

I prefer to do casual reading/relaxing under yellow light ("mood lighting"), and work/bathroom under white light.

This may seem like a binary issue, but really it comes down to setting and personal preference for the light used therein.

Disconnecting the theme selection and density option makes no sense from a UX standpoint. Although I actually like the new color scheme, it's lacking in a number of ways, not least the inability to visually differentiate between different google accounts (I have 2).

The reason I compare it to Apple is that the Google settings menu often has too few options. I don't want all my troubles simplified away, I want choice and configurability. I like advanced mode.
Finding memory leaks
Gordon Ramsay claims spyware used to hack into his email
Good feedback.

1. I think that folks graduating college don't have a lot of tech talent or what employers consider tangible skills.

2. I think many companies would rather have someone with 10 years on the job and a refreshed/refined skill set.

3. This is just a back-of-the-envelope thought bomb.... $53b is nothing, but the truth is the government does not deploy capital in an intelligent manner.

4. Only greed and vision-based entrepreneurs can execute on this plan. So, I'd just give 'education loans' to founders, like we did with Tesla and Fisker to do electric cars.
Because you'd have to have cameras on every single intersection and it raises a host of privacy issues - you'd effectively have a panopticon with a central point of control, which would provide would-be securocrats with a single point of leverage.

How You Can Legally Make $1,000 In One Night In NYC
Its a nice Dynamic programming problem. The beauty of DP is that simply memorizing one application of it does not guarantee you a solution to an entirely different problem that might have a similar Dynamic Programming solution. Look over the TopCoder SRM archives if you don't believe me.

So even though you are retiring this one, coming up with something similar that tests for basically the same things shouldn't be impossible.

Seminal papers on distributed systems
Hmm, the finance/economics divide is reminding me somewhat of the morality/legal divide. It's tempting to look at the idea of basing all your decisions about viable strategies on hard finance data as being akin to basing all your moral judgement on whether an action aligned with current laws. The latter seems obviously flawed, but at least it offers some degree of empirical certainty - whereas nobody can actually agree on a standard of morality (there are many differing philosophies etc.).
I think its a good possibility. Germans feel they are subsidizing the Euro-Zone periphery countries. Now with the ECB having to continue to issue currency in exchange for bank liabilities and national government bank liabilities, Germany may perceive this as inflationary ( though it is probably not) and given German history ( Wiemar, etc) they are sensitive to this type of policy. As such, wouldn't it be much easier for Germany to leave the Euro than the reverse?
sure does.

We are doing that at Mahalo now, but that requires a really motivated person obviously.

We've identified a spectrum of learning that runs from quick how to videos on one end all the way to the University of Pheonix on the other end.

In between there is very little, but what's there are companies worth
100s of millions to billions:

a) lynda.com ($50m in revenue),
b) rosetta stone http://www.google.com/finance?q=rossetta+stone
c) wiley (makers of 'for dummies')
http://www.google.com/finance?q=NYSE%3AJW.A&hl=en

There are a half-dozen milestones I can see... Mahalo has half of them:

1. individual videos that teach you something you want to know right now.

i.e. how do i make a lightsaber effect in photoshop?
http://www.youtube.com/watch?v=VSSb5l6hHnY

how can i augment breasts in photoshop
http://www.youtube.com/watch?v=xCAYwqaUoIc

2. a course that teaches you broadly about how to learn a program,
that's available on Mahalo.com (or maybe a paid iPad app?).

i.e. learn photoshop
http://www.mahalo.com/learn-adobe-photoshop-introduction/

3. a course on Mahalo.com (or an iPad app maybe) that teaches you how to solve a
specific longer, more complicated task

i.e. how to make a movie poster
http://www.mahalo.com/photoshop-video-tutorial-how-to-make-a...

4. A course that you attend for one to three days for $99-299 on a topic

we haven't done this and don't have plans for it.

i.e. Master Adobe After Effects, Master SEO, Master Social Media
or Master Google Analytics & paid traffic (StumbleUpon, Google
Adsense, FAcebook ad network).

5. A certification/degree that takes four months full-time where you learn
3-5 pieces of software around a specific skill (i.e. publishing, advertising buying/selling, seo/social media, graphic design, html/webdesign, ecommerce). This would be soup to nuts followed by a four month on-site mentorship where the company gets paid $1k a month to take you on.

6. A college where you go for two to four years for $20k a year that feels more like a job.

I'm not sure if Mahalo will do 4 through six... maybe after we get 1-3 right. :-)
