Re: the Air... Man, Apple has balls.

The 11.6" is interesting, note it's 720p exactly (1366x768). Note also he said he sees it as the "future of the macbook", and the future of the macbook has no obviously removable/upgradable HDD (it's like RAM on the motherboard, so maybe it will somehow be upgradable).

People who didn't like Apple products yesterday aren't going to like them today either, but it's interesting stuff...

edit:

Flash storage ranges from 64 gigs to 256 gigs (depending on size/choices).
Good idea.

To clarify, client owes me $273. It's easy to confuse: he paid $150 deposit and offered additional $150 for the orig files. I'm asking for additional $273.
good point, looks like stack overflow does this pretty well. there's also https://www.idselector.com and http://wiki.openid.net/Gallery
Yes, we're looking at similar kinds of approaches for WatchParty users. In all likelihood we'll build something that works with GoogleTV and AppleTV, but who knows?
Ask HN: Who is signing up for the Mac App Store?
Mr. Jobs just let the world know that he is bringing the successful app store model to the Mac.

I know a number of members already have applications for the Mac. Will you be bringing your apps to the new store?

Are you going to create a new app for the store?
Haha the croissant story is awesome. I'm amazed that worked.
OK, here's a really biased point of view. The author says:

It's OK to suck at math; you won't be using much anyway.

I'm not sure how this stereotype got instilled in
me, but I'm slightly embarrassed to admit that I was
surprised to discover how little math is involved in
day-to-day programming, ...

That depends. The amazing thing is how knowing math can help in so many unexpected, tangential, apparently unconnected ways. Time and time again the guys I work with do stuff that would be easier if they knew more math. When I pair with them they frequently say that they wish tehy knew more math.

It's OK not to have a PhD, it's OK not to have a degree, but at least knowing about, and having a good, intuitive grasp of what goes on in topology, linear algebra, analysis, graph theory, game theory, logic and more is immeasureably useful.

Unless you're doing the kind of coding that really doesn't require design or algorithms or data structures or communications or database work.

I've never used stuff I did in my PhD, but time and time again, continuously (and I use the work correctly, I don't mean continually) I've used the stuff I learned on the way that enabled me to do my PhD.

Learn more math. It will be useful, even if only to give you the option of rigorous reasoning.
Mine are more like frozen embryos. Hopefully I can find a surrogate for a few of them.
May be its only me but may be because of the UI, it looks very confusing, HN is very straight forward.
"By the way, no one in America (besides anorexic rich girls) is starving."

This absolutely not true, some students only meal of the day comes in school with reduced or free lunch. Not every poor kid is accustomed to nothing but what McDonald's serves.
I don't understand why the media lets them get away with it.

Politicians do this constantly. In the last US VP debates Palin didn't even bother answering something related. She'd say: I'm happy you asked me that but I just want to mention [cue pre-prepared talking point that doesn't have anything to do with the question].

Why do interviewers allow them to get away with such obvious tricks? One of the reasons Andrew Warner is such a good interviewer is because he doesn't put up with that kind of weasely response, he'll just repeat his question until it gets answered or he gets a response that directly addresses the fact that the interviewee doesn't want to answer it.
> You mean evaluate people based on who they are versus what they say? No thanks.

I don't know. I usually find that knowing who people are often provides some context to what they are saying.
NYC - Factor Tree (http://thefactortree.com)

We're a young startup creating an online education platform designed to build a solid foundation in math for kids from preK to 6th grade. We're working on some cool ways to provide every student with a tailored curriculum that adapts as the student progresses.

We're looking for someone who's comfortable in Java (or very similar language) and has a good foundation in web development. You'd be working closely with the lead (only) developer to iterate as fast as humanly possible to put our product in front of kids and parents.

If you're passionate about helping kids learn, send over a few links to things you've worked on (more important) and your resume (less important) to recruiting@thefactortree.com.
If I am using SBCL, then Hunchentoot. If I am using Franz, then I would use Portable AllegroServe and WebActions, both of which are installed and ready to use.
sorry, what i meant there wasn't literally pow function per se, but a function which does the job..
From http://www.yosefk.com/blog/my-history-with-forth-stack-machi... :

Look at the chips he’s making. 144-core, but the cores (nodes) are tiny - why would you want them big, if you feel that you can do anything with almost no resources? And they use 18-bit words. Presumably under the assumption that 18 bits is a good quantity, not too small, not too large. Then they write an application note about imlpementing the MD5 hash function:

"MD5 presents a few problems for programming a Green Arrays device. For one thing it depends on modulo 32 bit addition and rotation. Green Arrays chips deal in 18 bit quantities. For another, MD5 is complicated enough that neither the code nor the set of constants required to implement the algorithm will fit into one or even two or three nodes of a Green Arrays computer."

Then they solve these problems by manually implementing 32b addition and splitting the code across nodes. But if MD5 weren’t a standard, you could implement your own hash function without going to all this trouble.

In his chip design tools, Chuck Moore naturally did not use the standard equations:

"Chuck showed me the equations he was using for transistor models in OKAD and compared them to the SPICE equations that required solving several differential equations. He also showed how he scaled the values to simplify the calculation. It is pretty obvious that he has sped up the inner loop a hundred times by simplifying the calculation. He adds that his calculation is not only faster but more accurate than the standard SPICE equation. He said, 'I originally chose mV for internal units. But using 6400 mV = 4096 units replaces a divide with a shift and requires only 2 multiplies per transistor. ... Even the multiplies are optimized to only step through as many bits of precision as needed.'"
This is disappointing. What a Flop.
I really like the Open Feedback Publishing stuff that O'Reilly is doing (I used it for the Django Book and Apprecticeship Patterns). Is there a list of what books are currently in the program? It would be nice to see the list of what books are available or at least what books have been "completed" through this program. I dug around the site for a while and I couldn't seem to find anything.

The best I could do was a Google search for 'labs.oreilly.com' that turned up a bunch of books that I wasn't aware of.
And for anyone who actually cares about proper linking: https://docs.google.com/Doc?docid=0AcmB_WI1jRkCZG41c2d4cl80O...
Because every Mac laptop and iMac for the past ~3 (?) years has shipped with a built-in camera.

edit: To be clear, "huge" is relative, it's a big deal for the potential legitimacy of Facetime since the potential user base just grew quite a bit.
Well, after having read the article... it appears that you pay $12/user/month (after the first 2) from your business for the software, plus $12/hour for development.

So, you actually are paying more for the add-ons to their software, plus you're locked in to their system.
Ah, my other unreleased side project has come to light. Time to add some login screens, then :-)
Thanks for your response. Hmm... see, I used to think starting with the higher price was better, but now I think it definitely depends on the feature set at the beginning.

Right now I'm planning on launching it mainly as a Minimum Viable Product, so I'm thinking of starting at the lower price and raising it as features are added. I think that waiting to see if people buy at the higher price may take too long, since I'll be trying to validate whether people are willing to pay for the product at all.

For the yearly price, do you mean remove the monthly option entirely and replace it with the yearly option? Are people more likely to spend $24 or $36 upfront than $3/month? I was planning on offering a yearly option at a discount...
If they use a bayesian filter (for example SpamBayes) they can train it to filter exactly the kind of SPAM they are receiving.

And with a little more of work, it should be possible to filter the words differently if they are in the address of the letter, the submitter or in the main text.

(And they should warn the users that if they use the free try, they might read it.)

It's not really gonna be a big deal, but you gotta consider there's an Apple keynote being broadcasted live right now, that usually means RDF is pulsing at 100%, so my advise is hide and don't question anything!
Right, the only metric I want to see is the roundtrip latency between when I submit my order to when I get my execution report. I just aggregate the timestamps in my FIX logs and usually quote the min, median, max when trying to compare exchanges.

Every exchange we negotiate with quotes us their ping-test results. I always have to remind them that there's a lot more to getting an order into the book (especially via FIX) than just TCP.
Ask HN: Best blogs/sites about business/startups/entrepreneurship?

Looked to me like the SSD is cooked right on to the motherboard.
Does anyone code on an Air? Just wondering how well the current ones do.
As long as the App Store isn't the only way to put software on my Mac, sounds like a great idea to me.

I heard Steve specifically say something along the lines of "it's not the only way" when introducing the Mac App Store.
I thought it was going to become an open standard...
You timebox something to encourage immediate action. Making it permanent or even long term may encourage investors to wait for the market to improve before acting, which isn't ideal for a bill aimed at improving the market.
Am I missing something, or is this nothing more than fluorescent lighting and an irrigation system neatly packaged?

Do plants grow faster in this environment? Do the shelves adjust for different plant heights? Does the payback change if you're growing anything but lettuce?

Also, it seems to me that this vegetable factory would only be suitable for a restaurant that had a very predictable and very specific amount of traffic coming in the doors; otherwise, you're growing too much or not enough of what you need.
Great case studies from amazing entrepreneurs!
Annual subscriptions are a good idea, thank you, and thanks for the references.
Not even an SSD, it's flash-meets-RAM.
Ask HN: Wacky or Alternative business models
Does anyone have some examples or experience with alternative or far-fetched business, adoption, or revenue models, possibly in tech?

For example, billing for time spent using a piece of software to millisecond granularity? Paying for up front customer investment and charge incrementally later (Xerox), but for software consulting? Paying someone to embed/use a framework (AdSense)? What are some of the wackiest revenue and adoption experiments on the web? Did they suceed or crash and burn?
One hypothesis might be that a more long-lasting bill is being drafted, and this an interim solution.
Here's my question: Who is going to make money packaging liberally licensed OS projects into the store.
The Air already had that color bezel...it was the last holdout, I believe (other than the white MacBook which I imagine is now replaced).
NSA’s Newest Recruiters: Cartoon-Leopard Twins
It's likely somewhere around 7-8 million, give or take. And, I have a feeling alot of that goes to Rovio, the developer of Angry Birds.

So, I guess EA's in-house "8lb. Gorilla" homegrown studio and mini-publisher for smartphones was stillborn, so they acquired one. Smart move. Chillingo has had a load of #1 app store hits from various developers; they seem to know how to pick 'em.
Unfortunately, it mistakenly points to iWork 09 trial download for now.
Oh look, a netbook.

But 1.4G? Really? I love how they keep saying "fast processor" in the presentation, where "fast processor" is apparently two steps backwards in CPU technology. :-) The GPU is decent, however.

Is it me, or does anyone else see the point? I hope this isn't the "future of notebooks", because that future would seem to be anemic performance.
This isn't a net neutrality issue. But it certainly is a "cheap shot" by Apple, just like forcing app store developers to use a Mac to develop for the iPhone. Using their position to further their position.
But they are still 'floating' in space (rather than top-aligned), and there appears to be no discrete 'title bar' area... I'm not too hot on this particular design myself.

As long as the App Store isn't the only way to put software on my Mac, sounds like a great idea to me.

That will be in Lion + 1. Gotta warm the users up to it, first.
It will be interesting to see how well it does on Mac OS X. I doubt it will bring in the same number of new developers as iOS did, but I imagine it will bring in a nice chunk of new revenue for Apple and hopefully help some indie dev shops reach some more customers.
Pass-through entity investors such as S Corporations, partnerships, and LLCs have special provisions to share the advantages with their owners. Read the law for details; the accounting could get complicated.
No, it's an SSD without a case.
I agree with you and must add that if someone truly enjoys their job, more work is not an issue. Often, an employee that enjoys their job (truly enjoys it not merely saying they do) will welcome more work as long as it continues to challenge them and test their limits. If you did something mundane such as answering technical support telephone calls all day, for example, and you found that you enjoyed it, you might push yourself to answer as many calls per day as possible. The higher your numbers, the greater your pride in your work. On the other hand, if you only received two telephone calls per hour and spend the remainder of your time sitting around, every telephone call that arrived would interrupt your 'waste of time', and you would begin to hate it. Sometimes more work can be a blessing.
Here is my big question: "How do I move existing customers to the app store version of the software without making them purchase it at full price?"
I have money in my own personal savings. I also am on the verge of incorporating.

Can I invest some of my own money to save some money in taxes down the line if I pay dividends to investors?
No word on Lion having a new Finder app. It is once of the main reasons I prefer Windows over Mac.

As an aside, the Mac App store is actually one of the ideas I applied to YC with. Guess that has no hope now.
I don't think they changed it. There is probably just not enough room for the glass pane. I expect future larger MacBooks to be shipped with the black bezel as before.
What do you want to get out of this?

What do you think you can get out of this?

What are you expecting to get out of this?

It seems to me based on that most recent email that you will get no more money.

Let's create a decision tree ...

+ Assuming you can get more money (probability 10%? Probably less given the racist rant)

++ You can only get more money by negotiating and handing over the original files. What are they worth to you? Yes, you have invested time, but that's a sunk cost. It seems to me that they are of no value to you except for the money you can get for them.

Options:

+++ Ask for your $273 and refuse to budge. You will get nothing, they will be angry. Return=$0

+++ Accept their offer of $150. You have a 10% chance of getting it. Return=$15

+++ Ask for $100. They'll be surprised and try to bargain you down. Stand firm. You'll get $100 with 20% chance. Return=$20. Best option.

+ Assuming you will get no more money, are the files of value to you? I doubt it.

++ Keep the files. The bastards won't get anything, will be angry, will do what they can to damage you. Return is less than 0. You need to assess how much damage they can do to you.

++ Give them the files. They'll be shocked, feel righteous and vindicated, but are unlikely to take further action. Return=$0

++ Give them the files and state that you would like them to settle, but they have no obligation to do so. Say that they offered $150, but for the possibility of parting without too much rancour you will accept $100. Probability they pay? Hmm. 20%? Return=$20

Personally I'd write a "more in sorrow than in anger" email that you (plural) have reached such a position, and that as a gesture of good-will you will hand over the files without obligation. State that the time spent on them was worth $273 to you, but acknowledge that they will never accept that. Say that you will acccept any payment they deem suitable for the entire project, and having done so, that you will consider the matter settled in its entirety.

You won't get $273 - decide what is the likely best outcome, and close the issue. I'd seriously consider giving them the files as a good-will gesture and walking away.
RIM unveils BlackBerry Style 9670
Breaking Apart the Startup in the Cloud - A Dramatic Shift in Company Building
I really (honestly) can't wait to see how they do in the market, because the prices are so steep compared to the metrics that other people look at when shopping for laptops (display size, storage, speed). I don't even think Apple is gouging here; the unibody construction and flash storage are both pretty expensive.

So, Apple is pretty much saying, "Yeah, price, we're really not gonna compete on that" ... if that ends up working out well for them, that could be an interesting signal to other companies.
Does this have to be an ordinary corporation, or does an LLC taxed as a C corporation count as a corporation here? It's a lot less hassle and paperwork to have an LLC.
Its about time this happened really. Its an obvious idea, and could potentially be a great user experience. I bet Microsoft have their own within a year.
Very good point, thank you. Yes, I'll definitely be testing the pricing, but since it's a new service I'm trying to avoid people not subscribing for silly reasons like "it's too cheap" or something.
I'm not discussing the article. I'm discussing the message about the article. I'm responding to the claims and arguments of that message. The relationship between my responses and the article are irrelevant.
Please let the RAM be upgradeable, at least from the apple store...
On the target page it says $1499...?
It's faster than Atom. If you want real performance the MBP is there.
You are right. Publisher and "The company behind" do not necessarily equal "maker of". Perhaps I should have instead posted the Reuters article titled "Electronic Arts to buy Chillingo for $20 mln".

Follow-up to: Python is now Python 3

I didn't spot anything that looked like a drive controller on-board. Form factor is much closer to RAM, too ... not that it matters much, it's just an interesting design decision.
Is it pretty common? As someone who does a fair number of software engineer interviews, that's a trick question. The real answer to "swap two vars with no temps" is:

1. Don't be clever in our code base. Use a temp variable.
2. There's various dumb tricks with XOR, and possibly add/subtract if overflows don't break.
3. A sequence of several instructions where each of them requires the result of the previous one may not execute particularly fast on modern processors. Instruction/cycle counts -- like 3 -- are great when there's no pipeline and no cache, but otherwise pretty much useless.
4. The things you're swapping might be local variables, and when the compiler has -O <anything> specified, local variables start getting weird, and "swap" can sometimes be done in zero instructions, namely by the compiler noting that they have now been swapped and using the other one for the rest of the basic block. (or further dominated basic blocks for that matter)
5. If the things you're swapping are in main memory, or even if it's not in L1, you're going to be incurring a cost much greater than the temporary use of a register. (and, if you don't know where they are and it might be main memory, this might dominate the average runtime)

The answer is definitely not "three xors".
TFA has "data" in the title. You weren't aware of what it meant and jumped to a conclusion. I don't see how it follows that the author is being sensationalistic.
I don't care about speed as long as I don't notice it. What the MBA has is probably enough for the vast majority of users, only the RAM seems weak to me.
Yeah. I'd write a longer comment, but I now have a hard deadline to get my Mac app finished. Thank you Apple!
If you consider their 30% cut as a marketing expense, it's probably a pretty good deal. For that 30% cut you're going to have your product in front of a whole lotta eyeballs.

It'll also be interesting to see if the app store agreement allows you to sell the same app outside of the store and, if so, if you're allowed to have different pricing.
What's the difference between a 'maker' and a 'publisher'? Anyone else confused?

I think it is funny.
I wouldn't buy this as a dev machine unless you're pretty sure you're not doing anything more than trivial local compilation. Unless you bike everywhere and the size is really important.
"I'd like it if the Air was about half the size. I don't know why Apple won't make something in between the Air and an iPhone." --pg, http://paul.graham.usesthis.com/

On another note, the 2 GB of RAM on the Air worries me--that's not a large amount anymore, and I'm dubious on swapping a lot to the flash memory--it'll be faster than swapping to HD, but swapping--especially if it happens a lot, as it would with only 2 GB of RAM--is a use case that puts a lot of wear on flash memory.
They just re-wrote the Finder for Snow Leopard, so that was a bit of an unlikely wish.
I downvotted you because I think it's harmful to the discussion to be dismissive of others and their opinions, even if they appear to you to be under some kind of a spell.

FWIW, whatever he said sounded attractive to me, but I think they have painted themselves into a corner having saturated their own high-end market with gadgets, and are now getting into the sub $1k notebook \w keyboard market. As attractive as their offerings are, I have no doubt that it's no match to the stampede of Androids that's gonna run over them; equally speced at half the price.
