Yes, depending on how the access and security is setup. If the user has access to the database, they can just open the _design document and edit the html template, JavaScript code, the view, list and show functions.

For those that are still confused a bit, couchapp takes advantage of the fact that couchdb is accessed via a RESTful interface. Documents and databases are identified and accessed with URLs.

Typically your client and couchdb speak JSON to each other. When you GET a resource, you just get back a JSON object.

However:

1. You can change the format of what you get back. You can also return back XML, HTML, XHTML, etc., instead of JSON.

2. You can add attachments to documents. Attachments can be images, html pages, anything. You can specify the content type and couchdb will happily serve those when you click the attachment resource URL.

CouchApp takes advantage of those 2 things. It renders html page templates saved as document attachments, and fills those in with data from some view (read: query), and then returns HTML.

It basically cuts out the traditional middle layer by performing that work inside the database.

Combined with the fact that replication works so well in couchdb, you can just move your web app just by replicating a database: a one-step process.
It depends how you set it up.
Absolutely. I'd love to talk to other HNers. I've had great success meeting awesome people here. My skype/YM is alexnhatle. Hit me up anytime. Cheers!
If we get deflation, as many people are predicting, then you can get several percent "interest" just by holding your money in cash. That's built into the interest rate expectations for a lot of securities right now. You wouldn't see these near-zero interest rates unless people were expecting the dollar itself to become more valuable in the near future.
Absolutely. I thought there would be more discussion of flywheels (or rather, I thought the article itself would actually discuss them). The article alluded to a long lead time for needed upgrades to transmission capacity, but I wonder how long it takes from placing an order to getting a flywheel sitting next to a windfarm?
The desiderata were not 'writing a quick directory traversal function'; these were and are a dime a dozen. The writer explicitly demanded something you could only contemplate in the context of a few programming languages, namely an unfold - fold over the directory system. This is why he rejects all of the no-brainer solutions; he repeats this again and again.
I emailed them about it after 8 was released-they have a 'non supported install method' for OpenBSD that a forum member wrote. They told me it SHOULD work for FreeBSD, but they're currently not devoting any resources to figuring out how to make it go
It's a perfectly valid question, no need to downvote the guy.

I feel like younger start-ups in particular have the attitude: "If you don't have a trail of your own work, you're not extremely self directed, and we don't have the structure to manage you". And I think that's valid. If you still want to apply to these types of companies you should organize and show off the projects you've done on your own on a day to day basis.

That said, there are startups that have a more mature process. A necessary but insufficient condition is that they have hired a product manager or two. I know we'd get your application if you use this tool, but you should check out Loopt because it is a more mature startup. You can contact me directly if you have questions (check profile for contact).

Oh of course. It's just that the meaning gets disconnected from the message along the way. Disk thrashing happens when you get close to 100%, but people quickly simplify "don't let my memory get used up to 100%" into "don't let my memory get used up ever."
Nah. A kid will keep you sane. Best cure for a bad day ever invented. Also, kids don't get cheaper as they age. Might as well get the task done quickly.

Just make sure spouse is truly on board. Your stress is their stress and vice versa. I might add that my wife ended up getting a graduate degree and a new career, and the experience brought the whole family (3 kids) closer.
AMD designed a 64-bit architecture. There were many 64-bit architectures around long before x86-64 in 2000.
Um, not to get all defensive, but we at STB are making quite a bit of money. It's probably over a million a quarter per developer. I don't know many people who can say that. ;)
What I find interesting is the Samsung Galaxy S. Despite Android being a "free" OS, which would supposedly enjoy a price advantage over the other OS players (Symbian, Windows Mobile, etc), Android phones continue to be sold at the same price-point (in the US) as the iPhone ($199).

But now, the Samsung Galaxy S is being sold at discount pricing. It can be found for $99 (with contract), and even cheaper.

Over the long term, it will be interesting to see whether Android can support the margins that device manufacturers need, or if competition among Android device manufacturers will drive margins to near zero in a game of volume. I wonder if the Samsung Galaxy S is the first example in a long term trend in discounting with Android devices. So far, that does not seem to be the case, as buzz for the Samsung "feels" mild, while carrier supported devices (Droid, etc) are doing well.

Its certainly more complicated given the third player (carriers), and how they subsidize device purchases, but if manufacturer margins do drop because of significant competition, Apple may be one of the few device manufacturers to thrive in this market.

Well, I wish you good health, and based on what you've written I almost certainly don't mind chipping in. But, the point remains that you're already sick, so what you need now isn't insurance. I have extra sympathy for a kid that can't get insurance through no fault of his own, but I wonder - do you plan to have kids? Hypothetically, if there is a 50% shot of your children getting the same disease as you, and you choose to have them anyway, should everyone else have to pay the million dollar bill should they get sick?

Anyway, apologies if I sound bitter. I'm really not :)
MobileTerminal appears to be fundamentally broken on iOS4, at least as shipped in Cydia (it was when I upgraded and jailbroke my 3G).

But, you can grab the latest version from the project's website, and install it via SSH:

"all this doom talk about a worldwide depression."
Pretty sure I'm one of the only few posters here that would say the words 'great depression'. and 'voldemort'.

"It's depressing"
I know it is. But we as a population have to realize we are in a depression, not just a run of the mill recession like the mass media would have you believe, so we can react accordingly and not doom our future offsprings to even greater suffering.

"As long as we're not seeing hyper-inflation, the general population still has food on the table and you can actually think about where you're going to take your holiday this year we're not even close." Hyperinflation, not yet. 25% unemployed in the last depression, but they had soup lines to not go hungry. US has ~20% unemployment, and we have food stamps/unemployment benefits mailed to our house. As for the holiday..well you and I, we're in the lucky 80%.
I agree that the person should investigate the company a bit more before shotgunning out his or her application. I don't agree the domain matters so much, what matters is something fuzzier. I'm not sure exactly how to define it, but consider that at the 'trenches' level YC funded companies do a lot of the same day-to-day tasks with the same technologies.
Just over a year old, and just past two years since Apple first showed it at WWDC 2008. Snow Leopard was a relatively minor upgrade even by Apple's admission (hence the price tag $100 lower than for previous iterations), yet it still suffered delays because of work on iOS.

Meanwhile, there was zero mention of anything Macintosh at WWDC this year, meaning we're probably at least a year off from any real news at 10.7, which would put us at 4 years since OS X has had any significant user facing updates.
why? if you are an application developer you should care about market statistics not what bloggers think of the phones.
Google's attitude toward perpetual betas extends to perpetual war rooms. Almost every feature that you'd recognize from the last three years was developed in a war room. The visual redesign was a war room (well, war cubicle). Real-time search was a war room. The search options panel was a war room. SearchWiki was a war room. The bar across the top was a war room. Pac Man wasn't a war room, but almost all the folks involved were in war rooms and avoiding the war at the time.

Basically, it's just putting all the developers involved on a project in a room together and giving them a clear goal (launching). Other firms might call this "Agile" or even just "development". Heck, still others would call this a "startup".

"We've always been at war with Eurasia..."
It's a subjective question so don't feel bad about projecting. I was coming from the diametrically opposed position where I have a very specific interest and background (robotics) so I couldn't go write web-apps even if the business side ("the next big thing") was extremely compelling.

I was mostly trying to understand how (and if) YC's alpha engineers would happily go work on "the next big thing", largely independent of what that thing was.
They don't officially support it. But they just run a normal Xen setup. Setting up any Xen OS that supports running in domU is relatively easy. There's a few people that have already done it for FreeBSD and NetBSD.

You can try it out locally by setting up Linux and running FreeBSD in domU. Then just transfer that image to Linode.
This guy sounds plenty technical, though. Also, PC-BSD starts losing the point of the unified system and kernel. It's essentially a FreeBSD fork with more GNU stuff.
Yes, it is. Most employers in California have probationary periods for new employees.
Why we need a new bank that works
I think FreeBSD boxes are generally used as perimeter boxes by most sys admins because of their reliability, therefore compatibility with virtualized environments is not a priority.
Debian has only recently settled on a 2 year feature freeze cycle. In the past, Debian has suffered from releases being pushed back due to constant feature creep in the name of stability -- that's much of the reason why Ubuntu was forked from Debian in 2004.

So the jokes may be dated in 2010, but there's a reason they came about in the first place.
"The whole idea of economies of scale is that they work better the bigger they are."

You just blipped over my point and did nothing to address it. Economies of scale aren't magical. They have diminishing returns. What economy of scale do you get at 100 million that you don't get at 10 million? That's a real question. If you can't answer it, or you answer it with something that just boils down to "Uh, something", you haven't countered my point.

But you know, even that's beside the point. People have completely lost the ability to understand freedom nowadays, which is why we're going to lose it. The alternative isn't "Federal plan or nothing", it's not even "Federal plan or 50 state plans", it's "Federal plan or States acting on their own". Believe it or not, and I realize this may be a cognitive shock which I recommend you actually think on for a moment, if poor little Rhode Island doesn't want to strike out on its own, it can actually form a partnership with, say, Delaware. Or nowadays for all geography matters, with California. If that doesn't work out, it can leave, it isn't stuck. Or it can choose to go on its own. Or it can leave it up to its counties. Or it can say "stuff it" and stick with a regulated private system. If the economies of scale are so all-important, than you shouldn't need to force people to take advantage of them at the point of a gun, they should choose it on their own!

(The real problem is that there almost certainly aren't any hidden economies of scale left. Where would they be hiding? Big Medicine is pretty Big already. "Economies of scale" is just an argument people make and hope you don't think about the argument too hard.)

It's never a choice between "the Feds do it" or "we sit on our hands", unless you've become so helpless that that really is your only choice. (And "you have to do everything on your own" isn't the other choice either. There's a ton of other options.)

And then we can find out what really works, because no plan survives contact with the enemy. Not even Federal plans.

A Lot of Ways To Make More Sales Online
You are mixing up too many things. You don't have to be a celeb on twitter/SO/GitHub to get into YC. In fact, I think majority of folks that get into YC aren't the most active or even active on those platforms you list. HN is full of YC founders who have very few posts. While some prominent HN members have gotten into YC, I think that is more of an exception than the rule.

That does not mean that I am not talented, smart, or motivated.

What do you suggest they do? There are thousands of people aching to get into these programs. Vast majority of them believe they are smart, talented and motivated. At the end of the day though there are only so many spots. So naturally, you need a filter of some kind--even if it is not perfect.

You know you are talented but I urge you to put yourself in the shoes of folks at the other end. How are they supposed to know you are talented, smart or motivated?
I'd be happy to move almost anywhere (but especially coastal places because I love the ocean). In a way, that makes it almost harder to figure out where to begin the application process. Any pointers?
I think you are being misled by the seemingly simple headline "how would you write du...". The question was not straightforwardly practical but deep in the territory of so-called 'recursion schemes:

The natural way to do this is to use an unfold to
generate a list or tree of all the files in the
directory tree, map over them to get the sizes,
and do a fold to get the total.

-- And similarly elsewhere, more explicitly, as he makes clear why he isn't interested in the 'obvious' solutions, e.g.:

Yep, this is a good practical approach if I just want
to "du". I'm looking specifically for the fold . map .
unfold approach ...

The interventions of doliorules and then winterkoninkje (whom you quote) were in fact the ones that spoke to his condition.
If your goal is to get the big payout, what the hell are you working at Google for? Most of the people that got the big payout from Google joined...right around when you did, or a few years before. Your odds of becoming an executive at Google are far lower than they are at succeeding with your own startup and getting bought out for big sums.

If you want a big payout, you're much better off working for Google for a couple years to build experience and a reputation, quitting and founding a startup, and then getting reacquired by Google in a $5-20M talent acquisition.

Most people I know at Google are there because they want to work on interesting technical problems without dealing with all the bullshit that comes from running your own business. Google is still very, very effective at that - quite possibly the best place in the world for an engineer that wants to do cool stuff, launch to millions of people, and not push their way through lots of hassles.

Because a person likely to set off the alarm is likely to be driving erratically, meaning a high probability of being DUI. Not everyone who sets off the alarms will crash, but there could be a high proportion of them who could easily harm someone else on the road.

Although by the looks of this system it is to be similar to a rail system, so I'm unsure if a side-on-side collision would even be capable of derailing this and causing serious harm.

Honestly, I'd be more worried about car-on-car crashes under these. I've seen how stupid people are driving under bridges. Despite no shape-change in the lane, people tend to drift away from any walls or support pillars as though they're afraid of hitting them, and I've seen it to the point of them cutting other drivers off.
This confirms my suspicions - SRE are looked at as inferior or "second class citizens" compared to SWE. It also confirms some of the interviewer bias I experienced (I interviewed for an SRE position).
That's the point of open source. Take what in the hands of a single company would be a monoculture and turn it into a vibrant market with lots of choice.

Yes, of course it wins. It's a better development model.
I think this is a good thing so long as developers are also generous enough with the grace periods that legitimate users aren't affected.

If you travel to a foreign country for a week and don't have international data roaming turned on, will you need to find a coffee shop and connect to wifi sometime in the middle of your trip to re-authorize your apps?

The nice thing is that it does leave these decisions in the developer's hands. If it's a network-centric app that accesses a web service that costs the developer money to operate (and thus piracy results in monetary loss), there's no reason not to have the license be strictly checked every time the app is opened. If it's just a game, maybe not so much, because someone probably will want to play it on an airplane.
You're absolutely right - it would be trivial to manipulate the rankings. Disclaimer: I highly recommend no one make any investments based on my site's picks! This is just a data mining demo.
Time of flight laser scanners (LIDAR).
Scanners on each side of the truck measure the shape of the wall.
you drive the truck down the tunnel once (in one system) it stores a map of the wall shape and then follows the same shape to keep the same distance form the walls.

Another laser scanner checks the tunnel ahead (and behind) for obstacles, other trucks, people, rockfalls etc.

On some systems a spinning laser on the top hits fixed prism reflectors with known position on the roof and walls, it constantly resects it's position from this.
You shouldn't buy that premise, because that's not what the article claimed was unreasonable.
See btilly's comment that mentions them. There is a lot of chatter about bankruptcy. It's still just chatter, with a small number of exceptions. Let us all hope it stays that way.

Mind you, I'm not guaranteeing they'll all go away, but it won't take very many bankruptcies for your returns to go below inflation. (Or worse.)

I might invest in specific municipalities, if that's possible for a mere mortal investor, but I wouldn't think it's necessarily a safer assert class than anything else right now.
* I've never heard of "footfalls." If your company helps local businesses get started and generate traffic from Facebook, Twitter, and other sites, just say it.

* I would find a way to emphasize this message: "Get special love if you're a cafe, bar, restaurant, salon or spa." I don't know what this means, but this sounds intriguing.

* Your headline, "Tweets, Likes, Deals, Check-ins, ..." made me think, "Oh, this is a deal or coupon site."
Didn't work for Desktop Linux. Many fans of Linux on the desktop would tell you its better than Windows yet it didn't come close to " winning"

"I can replace "Republican" with "Baby-eater" in a description of the GOP platform and it reads just fine too,"

Well, I'd say that says more about you than Republicans. It does change the semantic content of the text, whereas my replacement doesn't. That's my point. Special interests bribe people too, or haven't your read the AARP literature?

Well, you probably haven't, but somehow someone with a vaguely similar name got crossed with mine and I started receiving solicitations from them. (I keep the fake solicitation membership card in my wallet. Fun gag to pull out at parties. At least while I'm still young enough to obviously not be a member.) Believe me, they don't really spend a lot of time laying out their political platform in that literature, a lot of which is rather more liberal than their base would really appreciate. They lay out all the benefits you get.

This is what I mean. Finding an actual difference in behavior between the "nations" and "special interest groups" is pretty hard. "Group of people of political interest where the group is kept together by benefits and collective action is taken on political matters both in and not in their direct charter"... if you rubbed out the word "nation" and asked me to fill in the blank, I'd write in "special interest group".
Been there, done that. Do not get into this unless you are comfortable that:

1. There is an objective way to measure your performance

2. That way does not depend on any team level/company level objectives like finalizing a business model, completing a prototype, making a sale, getting funded - as a fresh grad, you will have little to no impact on any of these, and so you should neither be rewarded nor penalized for these

3. The current finances and burn rate of the startup makes you feel comfortable that the company will have the money to make the upgrade without hitch.

4a. You have absolute trust in the founders that they will stick to their word

4b. get the criteria in a contract

on second thoughts, if 4a is not true, you shouldn't join the startup anyway - startups have a lot more dependent on the founders being moral rather than a large company where everything is process driven.

Also, if you have to go the 4b route, you will potentially leave them with ill feeling towards you ('this guy doesn't even trust us'). Meaning you wouldn't/shouldn't get hired.
OpenSolaris is the only platform that I'm aware of that supports ZFS and has stable, fast iSCSI Target support. (FreeBSD initiators don't even mount iSCSI LUNs on a reboot. I happen to like FreeBSD anyway, but it's not quite there for iSCSI.)

In plain english, OpenSolaris (the right version at least, avoid de-duplication) is the only free platform I'm aware of that will give you a fast, stable, iSCSI server with a file system that's basically impervious to corruption.

The only one. Seriously. COMSTAR and ZFS are that big of a deal. They aren't "nice to have"s. They're solutions that allow you to spend a couple grand on a box, put a lot of RAM in it, attach a JBOD, shove in a few SSDs for read-cache and write-logs and you can duplicate the performance million dollar storage systems on the cheap.

You can do this with very little effort on commodity hardware. You can start as small as you want and scale as large as you want. You get snapshots, clones and replication with barely any effort.

Sun's whole storage strategy (Sun Unified Storage) was built on nothing more than exactly this with a pretty Web interface sitting on top.

OpenSolaris is a real pain for a lot of things, but when it comes to storage nothing else comes close (that I'm aware of).

Don't be scared that you'll lose an alternative to Linux. OpenSolaris isn't any good as an application host if you're expecting anything close to modern GNU tools. Be scared that you'll lose an alternative to NetApp.
