U.S. Real Estate Investing Pitfalls to Avoid
Solar energy changes the shape of the nano structure. Shape is retained. A catalyst (heat, or flash of light) can cause the shape to revert and release stored heat energy.

"The only problem with this method is that it can only be used for heating an area. Attaining electricity from this method would require another step. "
If you're using Mercurial instead of Git you can create a mirror on GitHub with little effort (unless you're doing something pretty crazy with your DAG): http://hgtip.com/tips/advanced/2009-11-09-create-a-git-mirro...

This also lets git users contribute to your project, so you get the benefit of GitHub's community without having to deal with git.
Great, but that's not because of any P2P elements but because your bandwidth is sufficient for a stream.
The difference between MIT and ITP
G+ is about moving everything into the Google "cloud". In a same way Facebook (and VKontakte, and whatever else) is about moving everything into their "cloud".

Cloud is a buzzword, it doesn't really mean anything here.

G+ is just a Buzz (thus, GMail) + GTalk + Picasa + Latitude + Google Profiles, covered under one convenient interface. You can't peer with it, you have to actually use it itself (i.e., have and maintain an account there). Yes, there are some APIs to control that account (FB has some, too), and you could have a backup copy of your own data, but doesn't really matter.

It's still almost exactly the same as Facebook.
As long as they have all the weird music I listen to, sure. Is there a way to check their selection without signing up? I don't see any way to check if they have Soul Coughing, Zyklon Boom, Любэ, the original Grand Theft Auto soundtrack, Tub Ring, etc? (These are the first few songs I see in my playlist on my iPhone.)

I'd be pretty pissed if I signed up and got a Top 40's equivalent for my money.

Ask HN: Which thought leaders would you like me to interview?
So I've been podcasting for a couple of months now on design, development and marketing.

Curious to find out who you guys admire and would like to hear on the show.

The ads are obtrusive because streaming the better part of the earth's digital music collection to your doorstep at speeds that make iTunes seem like a turtle costs money. That bit may have evaded you.

Refuting your (IMO somewhat unfounded) statement on who in the US are going to love it, I'm a heavy music consumer (both in breadth and depth), and Spotify works especially well for me. In a purchase-song model, I'd be out many, many times as much per month than I am now (which also forms the disclaimer for this reply: I've been a premium subscriber for ages).
ActiveState Moves Stackato Cloud Platform to Beta
Not everyone reviewing resumes at BigCorps are bad. For what it is worth I work for 'BigCorp' and when looking for new guys on my team I do read any code I am given and go out looking for any code on GitHub and elsewhere. Internal transfers are easier as I don't have to do any hunting and just go looking through our internal repository at their commits.
But don't you own those books on your kindle? (Ignoring the arguments about whether you truly own something they can delete remotely, etc.) If you bought them, access didn't replace ownership - it supplemented it.
It's not just a version problem; I'm on the Firefox 8.0a1 nightly, and I got the same error.

A gap year for grown-ups
So banning the accounts is the end result? Aren't these throwaway accounts that can be recreated in a second? It seems like a reasonable concept to filter the Tweets from getting to me in the first place, I'm guessing a "spam box" is a little too complicated for Twitter though.
As mentioned, this is on a single VPS with 256 MB of RAM. Each Apache process needs about 25 MB of (non-shared) RAM, so actually 8 is pushing it. We're using mpm_prefork. There's no additional proxy nor cache.

My point, specifically, was how low you can go with a cheapo VPS. We hold up fine during an HN spike. (We're B2B and not a destination site, so our usual load is trivial.) Even during an HN spike you're getting tops of 2-3 visitors per second, which can be dished out reasonably well with 8 workers.

The monit thing kicks in after a 30 second timeout. With the configuration above, we don't get that because of load, but rather when something else has gone wrong (specifically there's a wordpress plugin that our internal status blog uses that sometimes hangs). But given the original poster's issue of apache getting so out of control that it took him several minutes to get a live SSH connection and a system load of 60, having monit kill things (and restart them) is a preferable stop-gap.

(Note: Our actual customer facing stuff is quite different; there we're using multiple servers behind an nginx proxy and using a combination of Rails, Sinatra and Java services. The basic web stuff is segregated off from those primarily for security reasons.)
> [1] When I talk about humans being meant or designed to live a certain way, I mean by evolution.

Do you think that humans will eventually evolve to work better in larger groups if they keep getting pushed that way?
Agreed. Git is obnoxious and Github offers me nothing, which is why I use Atlassian's Bitbucket. But the assumption, silly and unpleasant as it is, is that "everyone uses Github." Well, no, they don't. I really could not care less "where the code is," as per the sibling post to this one; I care for "where things don't aggravate the hell out of me," and that's emphatically not Github.

I disagree, however, regarding Ohloh--too chaotic, too messy, too many false positives. I don't think that, right now, there's a good solution. Something to think about, I guess...
10,000 Year Clock Begins Construction Thanks to $42 Million from Amazon’s CEO
I just like how G+ helps me share internet jokes with my friends, and at the same time, still be within my anti-social comfort zone.
i don't like "you must have the knowledge of how.." based arguments. how expensive is this knowledge? bored undergrads at good to decent schools learn enough to pull this kind of thing off given a few K in bootstrap money.

organized crime has both the will and the funds to do something like this. so could an independent person... you're talking $50-$75k and 6 months of a persons time to figure out how to delete someone without anyone even thinking it was murder?

the advantage of "hacking" the ECU is that by making changes in software you can make changes that can't be detected by a mechanic or by a vigilant pre-drive screen of your car. after i read the autosec.org paper my first thought was "this is dumb, it requires physical access to the car to pull off, i already have that, i can perform hundreds of other types of physical sabotage to make the car crash. nothing new here."

a few weeks later i realized "wait a minute, if i make a change in software, it can theoretically remain undetected forever before i activate it. also, nothing the operator does to find it could work. also, if i die in a wreck on the freeway that looks like i just lost control of my car, will the state police rip apart the wreckage, find the ECU, and verify that it hasn't been tampered with? will they know how to? will they even think to do that? and even then it wouldn't matter because the software could erase itself from permanent storage just-in-time..."

there are a lot of advantages and i think the barrier to entry is a lot lower than you say it is.
Heh, neither, but I'm pretty sure I got it (or terms like ObJoke) from some usenet group back in the day.
Car firmware developers know the exact hardware, needs, and uses in every case. Think about where most bugs come from: people doing things the developer didn't expect. Cars don't have many inputs, and those few inputs don't have many possible values.

CyanogenMod 7 for Milestone A853 RC12 (July 13), 5 Point touch?
Yes this is the one I'd probably recommend. They may already have an html5 course. There are also wiki sites like wikispaces.com or you can use wordpress.com or there are sites like instructables.com

For what it's worth, here's my course on web development: http://internetdev.usu.edu/notes We just cover the basics of HTML and CSS, and then jump into using a content management system (drupal). I hosted students' drupal sites myself, but there is also this free drupal hosting site: http://drupalgardens.com/ For the basic HTML/CSS part, I tried out http://kodingen.com/ to let students do everything in the browser since the computers are locked down here. It has some issues, but worked okay.
I can guarantee that it works pretty well on the ExoPC.
Cohort Metrics For Startups Revealed
Interesting, but this doesn't address the other problem--I fundamentally dislike Github! (I use Bitbucket because of consistently stellar support from Atlassian and an overall pleasant working experience.) And going outside my current, working ecosystem for benefits I consider dubious at best--the overwhelming majority of open-source projects get no outside commits, ever, and magic Github pixie dust doesn't really change that--isn't really a good use of time.

For me, Git and Github are both problems with this "GitHub's your resume" thing, not one or the other.
OK, thank you. My high school math teacher was dyslexic but as he told it, it was an issue with letter rotation, flipping, and swapping, which is what I've heard from other sources (including local SLTs). Maybe that's something that depends on native language or the type of dyslexia you have.
An Open Letter to Jeff Bezos
This is pretty par for the course in the Windows world. There is no consistency, even within many single applications.

Aside from the various UI paradigms Microsoft has espoused over the years (eg. the 2003 sidebar, the 2007 ribbon, the 2010 tabbed ribbon), other vendors think they have their own intelligent concepts of how a UI should look.

It's just a damned good idea to RTFM, or at least skim it. I skimmed the PuTTY FAQ on day 1, many, many years ago.

Seems like if one couldn't figure out how to cut and paste in PuTTY, they'd check the docs.

All the commotion about Google Plus
I have a similar problem on my Droid X. Sometimes the back button goes back a page (such as in a web browser) or while reading a message back will go to my contacts list (in google talk or google voice).

But sometimes, in the same apps, the back button might take me back to the home screen (If i answered a message from the notification bar), or a previous app if something launched a browser.

It's incredibly aggravating that the behavior changes, and especially so as Android devices have a home button! Back should be constrained to a specific application. Otherwise in google talk I have no reliable way to get back to my contacts and usually have to make a trip back to the home screen to directly launch the talk app.
I agree. Also why not use a full page cache, WP super cache allows you to generate the HTML version of your site and then serve the static HTML you don't even need to spin up the PHP.
Thanks! Used cVSY9gFdxWhdEz7Z .
"But it's your own fault if you have to fire employees because Google changed their primary search algorithm which tanked your traffic. "

I used to work for an ecommerce site. Over 60% of our traffic and sales came from google. To handle those orders we hired people, then if we lost ranking in google we would have to fire them. How would that have been our fault?
There's also so many diffrent kind of impact. Like albedoa and codeodor said, the graphic is poorly labeled and the data poorly categorized.

It turns out cars are catastrophically poorly planned then. Check out http://www.computer.org/portal/web/csdl/doi/10.1109/SP.2010.... -- they found they could cause the engine to stop, or the brakes to come on individual wheels by hacking the internal car network (Canbus).
A Neat Python Hack? No, Broken Code.
It's not problem of web servers in general, but specifically Apache.

HTTP keep-alive connections are faster (saves 3-way handshake on subsequent requests and allows pipelining).

The problem is that Apache implements them in a horribly inefficient manner (thread/process and all its memory kept in use just to hold on to a socket).

If you use nginx, lighttpd or shield Apache with haproxy/varnish, then you can easily have keep-alive enabled and clients will see better performance.
Even if a manufacturer didn't go for him, I'd be very surprised if the licensing fees were being payed for the MP3 codec.
2. Probably a month may not be enough to experience the disappearing playlists (actually, that should be called disappearing tracks, as playlists are still there, just tracks are greyed out and you cannot play them anymore). I've got whole disks greyed out from my playlists and created a ticket on getsatisfaction about a year ago. Their answer was that this is not their fault, but the industry's… copyright, etc.

I don't blame them, we know what the industry is like.

3. Beatles not so much for me (I've got their discography on cassette, cd, mp3… so I sync it with spotify), but Metallica… sad but true.

4. Never had a problem with Spotify + Skype, but I would suspect it's Spotify's fault. Why? Because on OSX I use BetterTouchTool and I get this message everytime I resume from sleep: http://cl.ly/1Z1u2n0R3H3o0w27243d ← I believe it could be related.

Isn't one of the big problems with solar collection towers, heating the fluid at night? They've been researching different types of salts and fluids that stay hot longer, so they can essentially run 24/7. With this, couldn't they store the heat and use that to heat up the fluid at night?

Or am I just way off here?
The success rate during their dev process was around 5%. Read the reviews in the android market - the one with people saying "only connected once out of at least 20 tries" are just about spot on.
It also happened to be a "fundig."

Its really only true for startups at this point. I've had plenty of interviews with the interviewer scratching their head when I mention github.
Video Email Marketing
Yeah, I've noticed that, too. If you jump directly into, say, an individual email on Android, you can't move "up" inside the application. I wonder if I'm just missing something.
9 Reasons Why You Should Have More Than One Email Address 
For those of you still using one email address for all aspects of their online communication, here are 9 reasons why you need to have multiple email addresses, and why it will simplify your life not complicate it.
Effective auto-moderator should check for multiple flags:

1) IP address (if it was banned in the last couple of months).

2) Registration Email address (was it banned in the past?).

3) Buzzwords (how frequently that word was used by banned accounts in the past)

4) Web sites (was it banned).

5) Age of the account (the younger - the more likely it's spam).

Based on all these red flags auto-moderator should calculate overall "spam rating", and above certain threshold accounts should be deleted automatically.
All key attributes of deleted account (IP, email, buzzwords) should be analyzed to train automoderator to recognize new spam).

We implemented such system and it automatically deletes most of spam:

At first read, I found myself disagreeing with his assessment, mainly because app folders have allowed me to have a single page of apps. I do find that the state of the folder remaining open is slightly annoying. As to his point, I agree with him when I think that home should bring you home, not to almost home.

As a counterpoint to this, I do find that I use the same 3-5 apps most of the time on my phone so double clicking home as actually most efficient as I can double click and tap to get to where I want most of the time, though sometimes I do need to swipe through the list a page or two.

You have to have a design patent to protect the "shape" of a product. They look a little like iPod nanos, but can Apple really protect ANY small rectangular metal music player?
If "exciting" means "Actually paying artists and not fucking them over constantly and abusing the DMCA to get away with it" then yes, it certainly is less exciting.

If they don't have the load, then it's just not at the top of people's priority stack. This doesn't seem like a terrible thing to me. It's not that caching and performance tuning isn't important, it's just that for people who don't have high load, they have many things that are more important to deal with.
It's also vital when merging. Agreed, too bad about the naming problem. Index, cache, staging Area... how many names does it need?
I totally get that. I'm beyond the phase in my life where I enjoy tinkering with blogging software settings. I'm far more interested in engaging in the conversation. But here's the counter argument: it takes a sum total of 60 seconds to implement. If you're using WordPress to host your blog, installing caching is beneath trivial. You click "Add New" under the Plugins menu, then search for WP Super Cache and click install. The only thing remaining is to turn it on.

If you're not using WP, you might use something like Tumblr or Posterous. In that case, caching isn't your problem. If you rolled your own blogging software, well, you already violated the principle that blogging is your primary goal.
Discover.com stores passwords in clear text
Had to reset my password earlier today -- they emailed me a copy of it.

Not only proving that they store it in clear text but also I noticed that it was downcased (or that they don't care about caps) and that it was also capped at 10 characters (it chopped off a few characters).

This is something like the 5th time in the past couple of weeks where sites have emailed me a password.

I goto a lot of startup events and I'd say a good 40% of them are storing passwords in the clear. You could argue that some of these are just emailing the password within the HTTP request itself but let's admit -- that's not too bright either.

All this talk about antisec/lulzsec is completely stupid when you have well known sites like this that implement these abominable security measures.

If you don't care about security you don't care about your customers and I hope your startup gets it's ass sued to hell and back.
Ironically, since this idea is on a Tumblr blog, I find Tumblr spam a lot more annoying. I help run a fairly popular Tumblr w/4K+ followers and occasionally I see that our posts are "liked" by users with names like "freebatteriesonline"; clicking on their name doesn't even take you t a Tumblr blog, just a dodgy battery sale site. The process of reporting spam Tumblr blogs is not intuitive -- the only instructions I found on the subject were on an eHow blog, for Pete's sake, and it's not clear to me whether I'm actually reporting them for spam or just blocking them so I can't see them.
15 incredibly useful (and free) Microsoft tools for IT pros
More nginx/stunnel ssl testing
I appreciate that you should have the option to choose which part of your working directory you commit. But I think the default should be to commit everything, like in SVN or mercurial. If I need to commit selectively in those systems, I'll disable some checkboxes, type in the filenames, build a changelist or use the record extension or something. The point is that I don't need to deal with it until I need it.

Also, it seems to me that git's behaviour encourages broken revisions (i.e. compiler errors, test failures) because your working directory doesn't match what you commit. And broken revisions will interfere with bisecting.
I'm sure if twitter really wanted to fix the spam problem, they probably would/could have already. They seem to have the resources to tackle the problem, this poses the question: do they really want to? I'm sure on the business side of things, they measure various metrics, such as; account creation and tweets/minute/hour/day - they can then go to advertisers and tote such metrics. Perhaps tackling spam would actually hurt their bottom line? In the end, how bad does spam really affect you? I barely notice it, myself.

In the end spam == more traffic == more $$.

I have used GoGrid for a while. And though originally very critical of them(check my blog) haven't had too many problems lately. For both dedicated servers and cloud servers I've always had a random root password generated. Not sure how this person ended up with one that was g0gr1d.

As for your question, by the sounds of it he ordered a dedicated server not a cloud one. Those usually take them the better part of a day to setup.
"Will contributions to Akka that use ASCII arrows now be rejected?"

I guess that this will be solved and has been solved in that commit with a formatting tool, but for me the answer to your last question is definitely "no", putting unicode arrow "aliases" in the language is a completely useless cosmetic feature.

How many programmer will type a unicode arrow manually? Is this really necessary? I'm generally against adding purely cosmetic feature like this one, if it does not improve the language in a clear and tangible way, just leave it out.
Perhaps a third dimension? Certainly there are simple and innovative hacks. Certainly there are complex, traditional hacks.
+1 for LessAccounting. We've been using it for a few years now and it works fine, and you can export your bank statements into it.

Recently we just brought on a 'real' accountant to audit our accounting and prepare reports (after a few years of pro-bono from accounting friends). Hence we are still working out all the details, but I'm pretty happy with the workflow if it pans out.
