Now, about the service itself: why would I prefer to use Parse over iCloud (which is something that must be disrupting their business plan)? The iCloud APIs will solve exactly the problem they are describing in their pitch, and not only do I (as an iOS developer) not have to learn the "server stuff", but I don't even have to worry about subscribing to a "server stuff" service, since iOS users get 5GB minimum of (free) storage space.

I suppose if Parse's APIs allow me to access the same data from multiple platforms (iOS, Android, etc.), and I'm making a x-platform mobile app that needs to save data, then that's a valid use case. But is it compelling enough?
This looks amazing!

BTW webpagetest.org can show you REAL 56k dialup waterfalls.

Another option might be to show users a link to the mobile version of your website. Many people who don't use cellphones wouldn't realize there is http://amazon.mobi for example.

I would think the biggest problem for dialup users is just large graphics/flash.

So just make sure the html and stylesheet shows up first by using deferred image loading and deferred external javascript by using a small javascript embedded right into the parent html.

Unfortunately with the reliance on jquery these days, many people have forgotten how to hand code small scripts like deferred image loading without large libraries.
Amazon deletes EBS snapshot blocks by mistake
From http://status.aws.amazon.com/

3:11 PM PDT Separately, and independent from the power issue in the affected availability zone, we've discovered an error in the EBS software that cleans up unused snapshots. During a recent run of this EBS software in the EU-West Region, one or more blocks in a number of EBS snapshots were incorrectly deleted. The root cause was a software error that caused the snapshot references to a subset of blocks to be missed during the reference counting process. This process compares the blocks scheduled for deletion to the blocks referenced in customer snapshots. As a result of the software error, the EBS snapshot management system in the EU-West Region incorrectly thought some of the blocks were no longer being used and deleted them. We've addressed the error in the EBS snapshot system to prevent it from recurring. We have now also disabled all of the snapshots that contain these missing blocks.

We are in the process of creating a copy of the affected snapshots where we've replaced the missing blocks with empty block(s). Customers can then create a volume from that copy and run a recovery tool on it (e.g. a file system recovery tool like fsck); in some cases this may restore normal volume operation. We will email affected customers as soon as we have the copy of their snapshot available. You can tell if you have a snapshot that has been affected via the DescribeSnapshots API or via the AWS Management Console. The status for the snapshot will be shown as "error." We apologize for any potential impact it might have on customers applications.
Why Philosophers Should Care About Computational Complexity
The reason nobody does HATEOAS in APIs is because the libraries used by clients don't encourage or even enable it. Chicken and egg.

Why should you care? The real potential is that you don't need a separate API site, you just add links to your existing HTML representations, and optionally provide JSON representations for bots so they don't have to download puny human HTML.

> Wealth is owning things that can make money

No, that's an asset. A car is wealth, and could be either an asset or a liability, depending on the car and what you do with it, but it's still wealth.
> The advanced answers to this question require spending a lot of time understanding string processing.

No, the advanced answers are a simple application of dynamic programming. If you've never heard of dynamic programming before, you're unlikely to invent it in response to an interview question, of course; but if you have heard of it, it might occur to you to try it on this problem.

(Actually, if you've heard of memoization but not dynamic programming, you might invent dynamic programming in response to this question.)

I think this is at the opposite end of the spectrum from your CSS example. Dynamic programming has nothing to do with string processing or with any other particular domain. There's a list of 29 significant algorithms that apply it at http://en.wikipedia.org/wiki/Dynamic_programming#Algorithms_.... It might qualify as "deep knowledge", but it's not deep domain knowledge; it's the kind of deep knowledge that would make you want to hire someone from a different domain.

This designer doesn't understand A/B testing.

In Ye Olden World of Direct Mail, everyone worked to beat the control. The control, your most successful mailing piece to date, was the benchmark against which everything was measured. You could modify the control, you could take a completely novel approach, but your work only counted for anything if it beat the control. Clients learned to ignore what they thought about a piece and care only about the results.

What the industry learned was that the only sane way to develop a brand new mailing piece was to imitate established controls. Books like Who's Mailing What and Major Mailers provided an index of successful mailings. Copywriters and designers came to understand the Darwinian nature of mailing and gave up on trying to predict what works. They learned that artistry was at best useless, at worst harmful. Their intuitions were completely wrong - the best-performing mailings were almost universally ugly, stupid and reliant on cheap tricks.

Outside of DM, designers almost never think in this manner. Throughout their education, they are taught to produce work that is aesthetically pleasing to the design world, with perhaps some concessions to accessibility. Aesthetics don't pay the bills.

The purpose of A/B testing is to measure the effects of a decision on the bottom line, but also to act as a driver for decisionmaking. A good DM designer has no hesitation in making a mailing piece look like a payslip or a bill, because he knows that such pieces work. His favourite font is Courier, his favourite colour is fluorescent yellow, his favourite adjectives are "splashy", "bold" and "eye-grabbing". He is blind to aesthetics and seeks only to drive the recipient to the next stage - to open the envelope, to read the headline, to the body, to the insert, to the coupon.

If you're looking to build a brand based on aesthetics, a designer is probably the right choice. If you just want to sell some product, 99% of them are a liability.
It's too easy for the web developers to just point the memory
leak blame to the browser and none of the users will be the wiser.

To be fair, there was a time (not so long ago) when browsers leaked obscene amounts of memory routinely. I'm talking about multi-gigabyte Firefox instances with no open windows at all. At the time, browser devs liked to announce either how this was absolutely nothing to be concerned about or how this behavior was a complete figment of the observer's imagination. As a result, web devs stopped caring about browser memory consumption, mainly because they were actively discouraged ("nothing to see here, move along") and personally frustrated about omnipresent leaky behavior they could do nothing against.

Nowadays, garbage collection in behaves much better. Even though browsers possibly consume more monstrous amounts of memory than ever before, they tend to give much of it back when the corresponding pages are closed. It's time to bring web devs back to the same table they were told to stay away from only a few years ago. But don't be surprised if this takes a bit longer.
You're not wrong about what they should do, it just has no bearing on what they do do. Given the choice between short term pleasure or long term pleasure for a short term sacrifice, most choose the former rather than the latter. Being able to delay pleasure is a skill many people just don't have.

You don't get to define how other people say what they can and can't afford or how they define the term afford. Many people don't use that word like you're using it. Afford to many people means do I have a few extra bucks in my pocked right this moment; it doesn't matter if they won't next week.
In this case I'm not too surprised at the lack of change, mostly because unlike with a little-known corporate bond or an inscrutable country nobody has info on, the S&P ratings don't really add new information that any economic analyst didn't already know about U.S. Treasury bonds. So, assuming anything remotely approaching an efficient market, any information S&P based its ratings decision on should've already been priced into the bond prices, because it was information everyone else has also had for a while now.

The Pros and Cons of Testing Commercial Compilers
> The truth is that I'm pretty bad at math, but in terms of logical syntax and parsing I am pretty good.

The sad truth is that you have a very limited view of what math is if you think of logical syntax and parsing as something other than math.

Frankly, I'm a little tired of the position calculus holds, where it is the pons asinorum for everyone who wants to do the more advanced (that is, non-arithmetic non-trivial-algebra) math regardless of what their true focus is. I think proof construction should be its own class and CS folk should take that and discrete math in order to move up the ladder. Engineers-in-training could take proof construction if they want a math minor and, yes, calculus their little brains out because calculus is what physics uses for a language.
After a few quarters of CS and internships in the industry, I realized how great opportunity it was to change majors in order to focus entirely on writing within a superb Humanities department. The lack of a CS degree hasn't stunted any bit of my work as an engineer, and having demonstrated writing skills can only make you more employable.

Ask HN: What's the difference between apps subdomain and the news subdomain?
http://news.ycombinator.com/

vs.

http://apps.ycombinator.com/

since when there is this apps sub-domain?

what's the point of the apps sub-domain?
It does help you. You're following a dynamic programming solution. Suppose that the maximum dictionary word is of length k. Then for each position in the string you have a maximum of k previous positions that you're tracking for, "We could start a next word here."

Once you've scanned the string, only then do you discover whether the whole string is segmentable.

Put another way, while you're processing you don't immediately know whether or not the whole string is segmentable. But having a trie can let you discard possibilities early. Discarding work early means doing less work means being more efficient.
> "purchase gold, " -- disagree:

Do you believe that gold has tripled its intrinsic value over the past 5 years? Or that virtually all other assets have lost 2/3 of their intrinsic value during that same time frame? Gold has very little intrinsic value (to my mind, at least), especially before the electronics revolution, and it is as subject to the whims of investors as any other asset. If you buy gold at $1700 today and it drops back to $500 in five years, you'll see the same loss as if you bought $1700 of Google and it dropped to $500. While I agree that gold cannot be multiplied indefinitely, the same applies to many (indeed most) other assets. The price of homes has no fixed limit, but neither does the price of gold. This is especially true when the market sells gold futures and such that are not necessarily backed by physical gold.

> But wait, couldn't this be said of stocks either? Exactly! Long-term savers will know this and not panic much. But those who talk about "wealth that evaporated" -- they were likely trading and speculating for a paper profit next week or month, not for "value-investing" or "storing savings". So both you and me shrug at them and say, "look again, no real wealth did evaporate! No factory collapsed, no car or house mysteriously disappeared..."

On this part, I agree. True wealth doesn't evaporate when the market drops. (That's not to say that a drop in the market can't hurt long-term wealth production; i.e. economic growth vs recession.) As you said, houses didn't fall down. Nothing changed except some paper values.

But then, anyone who understands how markets work should understand that wealth is not truly created or destroyed by trading in the markets. It's just exchanges of wealth. If you've got a share of stock and sell it to me for $100, the same wealth exists after the trade. If I turn around and sell that stock to someone else for $50, the same wealth still exists. The paper value of that stock might change, but no actual dollars disappeared as a result of the transactions. I lost money, but the economy did not. (I do believe that stock and commodities exchanges can themselves be real wealth, though, in the same way a village market is wealth.)

Given that all of computer science is based off of math at some level, i'd say math is more important than you think.

There's your problem right there. He isn't talking about computer science, he's talking about actually programming.

Sad thing is, on HN, many more people will probably support your side.
Your model itself is a significant assumption, though. Consider the Clinton tax hikes combined with some moderate restrictions on growth in spending as a counterexample: they ultimately led to the closest thing to a budget surplus we've had in our lifetimes, ignoring details like whether we technically were in surplus or not.

It is fair to ask whether that's sustainable, as in the 2000s we saw our politicians take those projected surpluses and spend them on tax subsidies for the well-off. Which, indeed, is just what that model predicts. But that just speaks to the need to elect better politicians and create better institutions to act as an endogenous curb on unjustified spending.

I'm not sure where you got the impression that parkour is "against" traditional martial arts. I had been training various martial arts for about 7 years before I started parkour, and then kept training for another 3 or so afterward. I'm a huge fan of martial arts, as are many traceurs.

I'm not so much a marketing guy for "parkour 4 hackers" as I am a marketing guy for "people finding something they love and doing it."

It's been incredibly influential in my life and it's helped make me who I am. Because of that, I do tend to go out of my way to help correct misconceptions and misinformation.

MCE shares its victimhood at the hands of content companies with the other media center solutions, like MythTV, XBMC, etc. The lack of a simple way to get cable TV into the PC (coupled with lawsuits targeting automated commercial skipping, etc.) relegated HTPC use to the brave few who were willing to set up IR blasters on their cable boxes or just download content instead of recording it.

It is the geek's torment to remember always what could have been, and suffer under what really is, thanks to the mighty powers that be (in this context the content companies, patent holders, etc.).

No. However Fitch put a "default" rating on Greek bonds, and there were headlines declaring a default.

The trick is that private parties are supposed to "voluntarily" forgive Greek debts. But they are negotiating with a gun to their head. And one way or another Greece won't be paying what it says it owes.

So some people call it a default. Others don't. But it is a pretty fine distinction either way.

Perhaps its beside your point, but this is exactly what's most important about learning how to write. There's a whole lot more that you learn by exploring 'fuzzy concepts' and non-precise systems. Approaching natural language like a science or system is delusional at best. Reading and writing "amazingly clear and concise documents" is just one way of using language as a tool.

How to make your website more engaging:
Yes! Written communication is so important, especially so with collaborative technical works.

Some tips: learn to state or restate a problem as a problem rather than an unimplemented solution. Consider: "I need a faster horse which eats less food" vs "I need a mode of transport which is faster and has less upkeep". This is especially important when dealing with feedback and bug reports from users. Learn how to extract the essential complexity of the problems they are facing and don't become biased by the possible solutions they offer up.

Also, be as direct, concise, and clear in written communications (email threads, commit messages, bug tracking comments, etc.) as possible. Make a habit of listing and relisting assumptions and presumed findings. Make a habit of summing up and distilling results, especially when new people are added to a discussion or issue. This saves so much time and avoids so many missteps due to ambiguity.

Additionally, teach yourself how to discuss technical topics without becoming excessively emotionally involved. Address the technical issues, don't fall into thinking that a criticism of your idea is an attack on you, learn to play devil's advocate. Learn to progress toward the best possible technical solution regardless of who had which idea.
I totally agree. Not only is Sense trying to create a different Android environment (visually), it's also not really useful most of the time.

I heard that this improved a lot in the last versions (my last Sense phone was a HTC Hero and no, I'll certainly won't buy from them again). My brother is satisfied. Still - this adds to the fragmentation. Trying to make it available (in a poor form imo, with these code drops) is just a try to strengthen the self-made split in the Android UI world.

It feels a bit odd saying "reward me for being your customer", but in terms of marketing, giving away a 'free' ebook with purchase does seem to be the best strategy. And Manning does seem to be leading the pack in this respect; even though the price difference between the two 'combo deals' might not be that huge, the way Manning presents it as a given that you'd want a digital copy of your technical book, I think gives them an edge for 'understanding their audience'. Not to mention that just by being on their mailing list, they send you a ton of good deals on a daily basis, with at least one super good deal per month -- all this, along with their consistently long list of 'MEAP' titles, have definitely made them my first choice when purchasing technical books.

As far as I know, Netflix didn't primarily target serial copyright infringers or the destitute. Most of the Netflix early adopters I knew were reasonably well off middle-class film aficionados, and movie piracy over the Internet was not very common in those days (as the majority of the country was still on 56-kilobaud modems and even pirating music was a time-consuming task).
