That brings up the 7th edition for me, while the app is based on the 9th edition. The 9th edition hardcover price is actually cheaper than the 7th edition, at $154.00:

http://www.amazon.com/Biology-Peter-Raven/dp/0077350022

But the "in-app purchases" section of the App Store page lists the online price as $119.99, so online still works out substantially cheaper than the new hardcover. I'm not sure where the higher price came from.

Regardless, you can do even better at other sellers or used if you're willing to get the 7th edition of the hardcover. At other sellers linked from Amazon the price goes down to about $100, and the used price is around $5. (Amazon does make this more difficult by displaying a lot of noise in the form of other books named "Biology" by different authors, even though the URL specifies "Biology-Peter-Raven".)

Thanks. I have noticed that any time I have a question related to programming, there is almost always an answer on stackoverflow.com.
Once the "App of the Week" feature began, sales immediately skyrocketed to more than 10 times the previous day; in one day, more sales were made than the previous week combined. The application peaked at 5,312 copies sold on July 25, reaching number two in the iPad paid apps chart.

So it looks like 5000+ downloads/day can get an app close to the #2 spot on iPad charts (and this particular app was helped by its being featured by Apple)

What does that have to do with the "ethics" of starting your own business while drawing unemployment? There is a personal cost of hopping from one crappy job to another that the unemployment system does not account for.
Ah, so it is "legal" to video an officer only under circumstances where the officer can and will "legally" prevent you from doing it and make your actual actions moot... yes... sounds quite congruent with the laws of Iran or the former Soviet Union.

Perhaps once people start using cameras with live feeds... they'll make it completely illegal.
I disagree with the whole premise that data science is the wave of the future. As soon as you collect a piece of information it is already out of date and is of very limited use. Weather scientists have been collection data since the beginning of the century and they are still no better at predicting the weather than they were at the beginning of the century. Economists are in the same boat. They have tons of data on markets but they still can't figure out what makes markets tick. What we need is not more data or data centric thinking. We need generative models that explain how the data is being generated and why it is being generated in a certain way. There is only so much you can squeeze out of raw data by computing numbers from it and so far I don't think the results have been that impressive.
It would be interesting to see how it copes with proxy servers (like the ones Opera use) that downscale images to reduce the traffic on mobile networks. It would be a good idea to checksum the code to make sure that it is what you're expecting to receive.
Presumably, it would just look like a GNOME app.
I use Authorize.net with 1Shoppingcart. It works pretty well. I'm starting to come up against some technical limitations (like a lack of trigger emails for shopping-cart recovery), but overall, I'm very happy with the solution.

EJunkie and Payloadz are actually very good for simple shopping carts. In fact, they can do some pretty complex stuff like cross-sells and affiliate tracking. When you start finding yourself hitting technical limitations (like upsells not working the way you want them to, or you want to do more complex trials), you'll know it's time to upgrade providers.

Thanks! I apologize that it's so general. That's part of the problem. I agree that I need to focus on something else, and focus of solving a niche need. Unfortunately after a long career in development, I really am not enthusiastic about more coding. I've been reading 40 Days to the Work You Love, which is a great book. I have yet to read What Color is Your Parachute and related books on finding the right vocation or calling. Mostly I was hoping that someone else here might have previously given up software development for starting up an unrelated company and could provide info about how they changed direction and how they determined their new path and any advice related to that choice. I know some niche dev work that I could do on my own, but I'm just totally not excited about coding anymore- basically I'm only excited about business. I would go back and do the MBA thing, but I don't want to end up working for someone else, so I think that just starting a business once I find the right idea and have a plan, etc. would be the way to go.
Yes, we'd be love to host this dataset for free. Send an email to upload@infochimps.com and we can arrange the transfer.
I wish there was a split view option.
I do pretty much the same thing. My difference is that, if I really like the idea after a few days and it's big/complex enough, I let it sit in my mind for a couple months and think on it when I feel inspired. Usually this has two end results: either I've fleshed it out a lot more, or I've dropped it for one reason or another.

The state court has determined that state employeesdidnt break a state law when recording students without their knowledge.

Notice how the state, which has a conflict of interest here, let itself off the hook?

Imagine if a old guy had done this by writing software that had attest mode accidentally left in? No intent to spy, but when judging citizens that doesn't really matter. The state cannot be trusted with justicevfor this reason.
Our parents and grand parents worked so hard to give us more choices than they had, and now that we have them and are choosing to navigate them in our own way, there is a whole class of people who think that is wrong.

Choice. Its a powerful word, and many in this generation have more choices than in any other generation before, or (quite likely) after.

Good on them, I hope they enjoy the hell out of it.
I see how this site works now. So, ill not be offering my thoughts in the future.

I recently stated this in another comment regarding payment systems.. I wouldn't rely on just one. A merchant account through a bank CAN get suspended or put on hold if you trip any risk ratios (e.g. inquiries, chargebacks, refunds). So, indeed, PayPal does have its share of stories of accounts being suspended without explicit reason; however, merchant banks have the same power and believe me when I say that they can lock/suspend your account, and hold your funds for 6 months without ANY detailed explanation and without interest.

Secondly, PayPal does have a new API called PayPal Adaptive Payments. It's very flexible.. pre-approved payments, distributed payments (refunds also mapped backwards), chained payments (multiple source accounts for making payment). Full details on their API PDF docs (easy to understand):

https://cms.paypal.com/cms_content/US/en_US/files/developer/...

So, even if you don't feel all warm and fuzzy about PayPal.. you should have an account handy, and think about having it as a payment option on your site. Some users swear by it because they don't have to share any sensitive credit card information (including CVV coddes) with the merchant.
Sounds great, but would be better on something with a better (ie more readable) screen. The application needs to be device agnostic.

If these guys can come through with the goods, it would be ideal: http://www.notionink.in/

Make it a HTML or something app so people with other devices (windows, android tablets/ereaders) can make use of it. (perhaps an idea for a startup would be a website/program that lets content producers create these without HTML knowledge. That is, a builder for interactive HTML5 based text books.)
My motto is if one can't be a general, one can be a great lieutenant, or in the floor-mopping case, private. I didn't used to feel like that, but over the years I've changed.
I am a lot like the poster. In fact, HackerNews is one of my homepages and I am reading this post as I read "Head-First Java".. Haha what a good coincidence. I'm hoping if anyone can lend out some guidance on what blogs we should start following and what websites that are out there to help us get started. So far, I'm enjoying this book. But of course, I'm not going to spent $45 on it.. The internet is free :D

Thanks for this post! Looking forward to more comments
Just on not writing it down: it tends to concretize it, while mind-stuff is more fluid. I've found that if I capture an idea before it's formed, the essence can escape.
Once of my biggest pet peeves with Skype is the way presence notification permissions are handled. The default way to make contact with somebody seems to be "add them to my contact list" which then initiates a message exchange of "Can I see when you are online". The problem with this is that and once granted, presence notification permissions live on the other person's computer and _cannot be revoked_. Removing them from your contact list does not prevent them seeing your online status and blocking them outright is the only solution. This is overkill however since I may wish to be able to receive calls/chats from them still but don't want to broadcast my online presence to them.

While I can of course change my status to invisible, this is a global setting and affects all my contacts. I now live in a permanent state of lurking on Skype, because so many business contacts have initiated contact with the "can I see you online" and would have taken offense if I simply said no.

In short, I would love to see better presence notification options in Skype including the ability to revoke permissions and to partition people into groups and assign a corresponding status to each group.
Tyler Cowen of Marginal Revolution has an interesting real-world analogue when he has to deal with q&a during his public speaking event. He believes that people are behaving in status-seeking ways and so forces people who want to ask questions to write them down and pass them up where he answers them anonymously[1]. Winer's 24-hour limit seems to be partially addressing this problem as well, but I agree with the comments already posted about that being too much time to care.

One possible solution I'm thinking about implementing in a new blog I'm starting is a separate Twitter comments account. This forces brevity and accountability among other things, and people could link to their own posts or places where my posts are (hopefully) being discussed. In addition, if the blog is successful, I could potentially see what comments are being retweeted, etc. and run some quick and dirty analytics to help determine high-value comments. Additional benefits would be connecting with high-value readers in a more intimate way that could improve dialogue as well as gently guide users to providing comments via email for longer dialogues. I'm concerned that 140 characters is too short to provide feedback, though the majority of comments I post on non-conversational sites seem to fit into that range.

Any thoughts?

This as 3 purposes,

1. show of some neat trick
2. hide code
a. hide code on a 3rd party site
b. hide code in an image that actually looks like an image ( steganography ),
thus hiding parts of the code within several images.
for a really good time, hide some unique data on
one machine that acts as a key
3. save per file system space

i think gzip uses the same compression algorithm as png files so, to reuse this is silly. the browser supports gzip anyways

i saw this as part of a 10kapart competition, and maybe they were trying to make up the difference between the actual size of the bits used and the file system size. i think although this is interesting, but, it defeats the point of the 10k limit; which, was there to show what one could do without server side scripts, and I think a build script .... counts.
This is what I love about JavaScript right now. The air of innovation is everywhere. It really is an exciting language to be developing in right now. It reminds me of the early days of Java.
Ask HN: Rate my startup beepl.com (http://alpha.beepl.com)
The best way to get users to answer questions is by matching the right questions with the right people.

Beepl does exactly that by measuring users' interests, their involvement in various topics, the quality of their contribution and the level of their expertise within a specific field.

We call it a social expertise footprint: http://alpha.beepl.com/user/stevenf

Beepl is a bit more like Vark, less like Yahoo! Answers - it's a question platform.

And we've got in twitter too (with the facebook soon to follow): http://alpha.beepl.com/twitter/

Launching in private alpha (or maybe even going live) in September 2010.

What do you think?

PS - I'm getting in new features daily, plus it's running off of a single 0.5GB gogrid instance (nginx), it may be that there're some things temporarily broken....

I don't consider the folks from my town (Baltimore) self-promoting new media douchebags. They're people about my age who I know socially doing what they would normally do but stopping to mention it every once in awhile.

I don't see it as "hey, hey, look at me!" but I have mellowed out a lot in the last few years, so it's probably just a difference of perspective. I'm optimistic with people I know and pessimistic with people I don't.

Funny, Buddhism theorizes that the whole concept of `self` is the ultimate cause of suffering and meditation is one way of releasing yourself from holding on to that idea.

That said, the sense you could have been having is that there is no `you`.
Ask HN: Which prog. language(Perl, PHP, Python, Ruby) should i learn?
Wondering what each of these languages are used for and which one would be good to learn. I know these 4 languages are similar in that they are general scripting languages but i want to know some more about what each language is specifically used for when developing. Is it better to start with one vs. another? Is one language easier to learn? I already know some java, sql...
Here's mine.

1. Ding! "Woah, what a great idea..."
2. Research. Spend the whole night up researching.
3. Brainstorm. (On paper!!)
4. Share with someone you trust or might be interested in working at the project. *Be careful here
5. Start looking for a domain. (I find this part the hardest lol)
6. Start sketching on paper. Logo and UI.
7. Research again, this time for logo and UI inspiration.
8. Design > xhtml > code > launch v1 ASAP!
9. Get feedback.
10. SEO
11. Repeat 9 and 10.
12. Repeat 12.
13. Improve > fix > launch more features.

Goood luck amigo! :)

+1 for finding the post via twitter.
I can literally stare into the thing for hours: reading books/articles, surfing, watching video. It's makes no further strain on my eyes than does an LCD monitor (though, full disclosure: I use a P-MVA screen, which is supposedly "better quality" as LCDs go), and I _have_ to look at that for hours a day for my work.

I think the people who don't like looking at the iPad screen for more than a few minutes base their patterns on personal or ideological beliefs, or are personally invested in another platform like OLED or e-ink (i.e., fanboys).
@swombat

I'm the actual author but thanks for the feedback I'll put it into good use. I'm new into this type of writing so I was expecting my first article to be not that great.

Either way, its helped me a lot since I've learned in ways I could improve further articles.

But why did you mention it to be a piece of linkbaiting trash? Links posted were to support my reasons. Also, I didn't collect any data since this was done through the help of other programmers so its not really a brain fart in the sense.

And poor? Honestly, I don't think its that bad.
Digg founder says Apple iTV launch in September will 'change everything'
1. DON'T write it down

2. Think about it for weeks and months and years.

3. Tell my various entrepreneurial friends about it and bask in the glow of their compliments.

4. Congratulate myself on being smart.

5. Dream about making so much money I could punch a cop and get away with it.

6. Dream about how great my life is going to be when I'm harpooning great white sharks from a helicopter that can turn into a boat.

7. Curse the idiots who came out with a product months or even years after my idea except it's executed all wrong and I woulda done it so much better.

8. Curse the same idiots who are now making so much money they can punch a cop and get away with it plus have that boat-helicopter thing.

9. A few weeks later I come up with a great idea. See step 1.

Note: it's not considered a criminal act, it doesn't mean any of these students (or their families who could also have been photographed, who again could file criminal charges themselves) cannot file civil charges against their school/teachers.

Under criminal law in the US, AFAIK in the absence of criminal intent it's very hard to get charges laid. Courts don't want to extend strict liability onto serious cases, because you'll be landing every doctor in jail for malpractice, negligence or simply not doing enough. I doubt courts would extend strict liability onto any 'spying' infraction, because it would make essentially any wiretapping, etc. to be prosecuted essentially as guilty-until-proven-innocent.

Although I know in the UK sexual offences are strict liability, and as far as I've seen it follows similar lines in the US too, so one inappropriate picture would have likely turned this result 180.
This actually refers to the programming language called clojure, not the concept of closure.
Yeah, we measure those as well. They won't be displayed, though. I should probably mention that it's all about the significance.

I've seen this in action and it's totally whickeeeeeeeeeeeeeeeeed!
what are your goals in learning this language?
It was definitely not convenient during development. When I was testing for IE9, every change in the code needed to be encoded to the PNG image. But having an automate build script really helped speeding up things. YUICompressor caught all the major bugs during the build process so as long as my un-minified/unencoded scripts worked, I was pretty sure that the PNG version would work as well.
Questions have context. Explaining them is easier if someone's there interactively prodding for missing context you failed to give. "Can I ask you a question?" == "Got a moment to chat interactively?"
I think you need an example of what it is on the front page, or at least linked from it. I think most people will be reluctant to register for something without knowing what it is.
