Ah, that makes more sense. Although a battery is a lot denser than an optical drive, so that would kick the system weight up. If you use some of the space gained to instead make the system thinner, you start to get essentially a Macbook Air. And I think it's fairly clear that Apple is moving in the direction of converging the Air and the 13" MBP.
Seems like a great choice to me. You're looking at a billion dollar business and opportunities like that don't come along every day.

You may be wrong.
I've experimented with this route as well via FireFound (https://www.firefound.com/) - $20/year for additional capabilities for the basic add-on. It's probably not applicable enough to most people, but subscriptions pay for server and domain costs plus a little more.
Congrats, as someone who has seen the hard side of the Travel Industry these are truly remarkable figures.

Great resource, thanks. Another great resource is, of course, the Khan Academy. See their precalc videos here:

The simple solution is to store everything in UTC, but that means the smallest resolution you can store is 30 minutes (some time zones are :30 offset, and you ignore the Chatham islands that are :45 offset - http://en.wikipedia.org/wiki/Time_zones). It's really annoying and I have wished many times everyone would just use UTC.
Any idea why people aren't building inductive charging into their devices yet? The tech has been around for years, and the only people using it are supplying special cases for your devices to make the darn stuff work.
I got their answer. Note that there is a wrong "solution" to this problem that looks like it might be right.

It is a very standard problem, by the way. Most books on algorithms will have the solution.
Which is weird, because resolution independence has been part of Mac OS X since 10.5. Only if developer tools are installed though, and it never really worked with Carbon applications, but those are slowly vanishing anyway.

I just activated it again to see how it looks and.. well, it could look better :) I tried the preferences and I've to admit I think they looked better (scaled up) in 10.5 than on 10.6.
The bouncing icon in the dock is definitely annoying.

I think vista (and seven ?) handles softwares updates in a more friendly way, asking you if you want to do the updates when you shutdown the system.
do you say this because your greedy algorithm solution of 450225 didnt work?

Nice succinct contest, I like it.

Problems are good, graded difficulty (don't want to discourage anyone with the first problem), solutions don't take terribly many lines of code. Low barrier to entry makes for a fun contest. Problem 2 is on par with a medium-hard ACM ICPC question, probably one of the harder questions I've seen in a startup-made contest. High five.
I think this is a really, really bad idea. It's been known to cause trouble for other companies before when the Lybian administration doesn't like what you're doing.

Some years ago I was coding for a inventory/financial administration completely built in OpenBasic (remember to leave space between your line numbers!), gosubs instead of functions and the like.

The problem is, that this was one of the most solid systems of this kind I worked on (think "hot code swapping" and "constraint driven development"), but mentioning it on a CV does not exactly evoke the same vibes as using node.js on couchdb.

Your Macbook sounds as though it came from the same batch as my wife's Macbook. The Apple store replaced her battery free of charge well out of warranty and also offered a replacement casing. This could be a UK thing as it's pretty clear that there was a period where Macbooks were being manufactured below acceptable standards, the "Sale of goods act" would apply.

I bought a Macbook about a year after my wife and mine has been absolutely fine, no cracking and still with a good original battery.
Finally. Apple is getting rid of the default, always-on, scroll bar.
I dread this because it makes the model I bought last year feel outdated! I can't see upgrading something like an MBP more than once every two years, though. That's reassuring since I know whatever that model is, it will be fantastic by current standards.

The only time my MBP breaks a sweat as it is, though, is on games: Half Life 2 and the PlayStation 2 emulator make the fans come on like it's trying to dry my hair.

I'm not 100% sold on my next laptop being an Apple, though. While my MBP is very impressive, it is also a quite expensive piece of hardware... and I'm not impressed by Apple's policies regarding iOS and the App Store. But what is the alternative? It doesn't seem like there is any other manufacturer successfully designs elegant, high performance luxury notebooks.
Illusion 'cloak' makes you see what's not there
Very valid comment. I do apologize for the tone, I certainly didn't mean to offend anybody.
So this was just a start. We built the product over the last couple weeks and had a few people volunteer their time to try it out. Moving forward you'll see more dedicated times from folks. We had another listing out a couple days ago, but the 6 slots of 20-minutes each disappeared quite quickly.

Btw, if you don't mind. drop me an email vladik dot rikhter at gmail. I've been meaning to connect with you in regards to your current startup. Thanks!
Oh, that's just Crazy Bob talking. If that had really been Apple's strategy, they wouldn't have alienated so many customers in the way they killed the xServe line last year. If they had really wanted to keep their toe-hold in that market, they wouldn't have said, "Let them eat mini Macs." I think it's simply the case that Apple's signature advantages in the consumer space don't translate into a 1U world, and they recognized that.
> Can you describe how a market would work if everybody thought about it the way you're thinking about it?

I don't have to; because NOT everybody thinks about it the way I do. It's a false hypothesis and thus not worth even considering.
Let's be honest. When people "use Ruby", it's very unlikely that they are using JRuby or Ruby 1.9. Similarly, when people "use Python", they are using 2.7 or lower, not 3.1.

The reason is because the older versions of each are the ones with the libraries.

But interestingly, this is not the case with Perl, as new releases have 99% backcompat with old releases. Even old code that uses a new piece of syntax (like "say" from 5.10) in the old way continues to work!

Ask HN: When will Yahoo shut it's shop.
My boss keeps bashing me up because I decided to use YUI3 as the js framework for an very important project about to last at least next 4 years. He keeps saying that keeping dependency on yahoo! is like beating a dead horse.

Not that I give importance to what my boss says but many news items about Yahoo! are very depressing. All is perhaps not well with Yahoo!.

Once compared with Google, today Google has left behind Yahoo! the way China has left behind India.
Ask HN: How should I structure my pricing?
That's not too bad. But does that all add up to more than 9 hours a year of downtime? If so, you're already doing worse than 99.9% uptime.

I would also bet your uptime is worse than you think if you're not actively measuring it. However, I'm sure it is "good enough". I doubt it is worth spending an order of magnitude more money to get better than 3 9's for your business, which is more or less the point of the article imo.

I find the percent availability -> hours of downtime chart on wikipedia to be a really helpful reference for these types of discussions: http://en.wikipedia.org/wiki/High_availability
Wait, who uses this service? Anyone care?
Need pricing suggestions. StartUpLift is a feedback-oriented service where we feature startups and help them solicit feedback from our community of users. The site was launched with the help/suggestions from HN users a few months ago. I am coming back to the HN community today to help me structure pricing correctly. What are your thoughts - is it too much, too little? What can I change in what I say on the pricing page? Currently there are three options - Free, $35 and $50. Free option simply gets a startup featured (no feedback guarantee). When you choose a paid option ($35 or $50), we invite our users (currently about 1,800) to submit their feedback. You will then be able to select and reward top three or 5 entrees respectively (out of many received). Competition helps maintain the quality of feedback. [Note: the URL in Title above is page 2 of the submission process, i.e. users are taken to this page after they submit details about their StartUp. Here is page 1 in case anyone is interested: http://startuplift.com/submit-your-startup/.

Thank you!
What are the best places to find practical advice on startups?
We're creating a search engine prototype for entrepreneurs as part of an SBIR project funded by the National Science Foundation and we need to index some quality resources and information for new entrepreneurs.

From the Apple page on Thunderbolt: "you can use existing USB and FireWire peripherals — even connect to Gigabit Ethernet and Fibre Channel networks — using simple adapters."

No, because it enables the user-agent to paginate content before the entire page has even loaded.

And presumably the page author knows a priori what the header and footer for the table are going to be, so why not transmit that information to the user-agent as soon as possible?

If you examine XSL-FO, they have similar constructs for what I am guessing are similar reasons.

There's no clear way to profit directly from these addons without doing something sort of spammy. The Mozilla platform just really isn't set up for it and it isn't expected by users. I'm not going to make a ton of money developing small open source utilities, either. You either use it to a gateway into something else (paid consulting/contracting jobs, writing a book, landing a regular job, etc) or just keep it as a fun hobby if it is something you like.

If you'd like to make money on the side focus on platforms where people pay for things or that have a clearer path for indirect revenue. (The web, Windows, Apple, Android, Facebook, etc.)

I know it seems like the numbers are there and you're providing value but it would be an uphill battle. When focusing on income, your energies are better spent elsewhere.
If it's too much complexity to track each user's preferences in terms of every other user's, you could also take a Bayesian filtering approach, similar to junk mail controls, and compute a custom front page based on each individual user's prior upvotes/downvotes.

In either case, the function of the voting mechanism will ultimately shift from generating the public front page to generating a custom view for each user. At that point, you could re-purpose the public front page as a selection mechanism to draw in the highest-quality users - perhaps by choosing a cohort of existing users to have public-upvote rights, or even by just applying old-fashioned editorial controls.

There's no way to get a clickable link in a submission - hence why there is usually a "clickable" comment (which just includes the URL - news.arc turns it into a link automatically.)
It's somewhat hard to say what makes a listing successful as it depends on a combination of factors such as location, technologies wanted, the company, the position and people looking to work with all of the above. And sometimes there's just no match. That said, we'll follow up with you directly to see how we can help you get the best out of your posting (and there's always our money back guarantee if your not entirely happy).
This is great. We're working on a startup that could use an open location database such as Hyperpublic. Keep it up!
It's 2011, when have you last time used an optical drive?

The actual facts and numbers here make a strong argument. As an iPhone indie developer I thought it was well worth the read.
Well, in our case we would normally just come up with a name ourselves. But because 50 dollars is worth a shot we're giving him some business. And something tells me there might just be more people in the same situation as we are. But I guess we won't know until he lets us know how many from HN decided to give it a go.
That would be me, too. For the last decade or so. Beginning the arrangement was not a problem for the reasons that 1) I own the company and 2) I relocated the offices literally a stone's throw away from home.

I chose to do this for lifestyle reasons, to spend more time with the family and to be able to do my own thing at my own pace, without employees (strength peaking upto 50) harassing me :-) with issues every now and then.

Has worked extremely well for me; no complaints.

I used this a while back when it first came out and it wasn't totally reliable (it failed to work with some IE6 png transparency hacks), but overall it was pretty good. It may have gotten better since then as well.
I welcome the changes to the CSS tools in particular! While the Inspector is full featured and offers some capabilities not found in Firebug, Firebug still feels more natural and reliable to me. The change to show unfiltered CSS rules is really helpful.

It's odd that Mozilla hasn't officially adopted Firebug as part of Firefox. While Firebug continues to improve, and the Firebug team does a great job, with Google is focusing on this area I suppose at some point I will prefer the Chrome inspector. Why is Firebug still a plugin?

On the darker side of web development, IE's development tools are typically lacking. Does anyone know whether they have been improved in IE 9?

I don't even understand why there has to be a blog post about this. When you make a major investment in a technology you don't just wake up one morning and rewrite it using another one.

Thats how you lose money and your competitive edge ... I had a small PHP app that I transitioned to Ruby on Rails ... it took 2 months (mostly because I was doing it part time and was only just getting serious with Rails) and that whole time I was falling behind to a competitor because I wasn't adding new features and fixing bugs.

I'm glad I did it in the long run, but still ... rewrites to take advantage of the flavor-of-the-month technology can be very overrated.
Now the question is how long it would take market to catch up with adapters/hubs or updated hardware.
Comments of the type "they're just can't be bothered to change" are idiotic, and whatever works for them it is fine.

That said, for newer projects companies are better off choosing another platform more suitable to their domain.

For example, if you want to do data-mining / language processing, there is no better alternative than Python. It has mature libs in that regard, good visualization tools, books on the subject come with Python source-code, and has bindings for frikin' everything (you can script everything with it, from Emacs and Vim to Gimp). Native extensions are easy as pie, working with forked processes is as good as it gets (comes with lots of really sweat libs), and Python also has Google's App Engine.

And Ruby on Rails completely blows away (IMHO, YMMV) every alternative for fast web development ... it's beautifully designed, comes with best-in-class plugins and I haven't seen so much activity in any other web-related platform.

So for newer projects, companies should try experimenting / investing in newer tools; otherwise the competition might just gain an unfair advantage. You shouldn't reinvent the wheel when people have been working on the exact same problem for years.

First there was a press release calling for anon to attack the church of hate or whatever they're called.

Anon shortly after released this press release calling it out as a hoax:

boycott Operation Westboro. If you really want to continue messing with them, just send them a few
male prostitutes and faxes of goatse. Nothing more.

I think the church leader has since released a statement that literally said "bring it," and this is likely why they have now been owned.

I imagine whoever did it made a point of covering their tracks very carefully indeed, I'll wager via simple wholesale destruction of the server. Some of them are definitely capable.

I have been pretty satisfied with my HP Envy 15 purchased last March, for roughly the same price that a MBP would have cost me. Differences between it and a MBP:

Slightly lighter.

No cool magnetic charger thing; instead, power brick.

Battery life is comparatively awful -- I usually get about an hour and a half. (I don't personally care about battery life.)

Envy has better resolution at 15" -- 1920x1080. Envy has what appears to be slightly better graphics card. (That is, a slightly better graphics card a year ago as opposed to what the new MBPs have today. It kicked the crap out of the last-generation ones.)

Envy has SSD+HDD instead of having SSD + built-in optical drive.

I'm personally much happier with it, since resolution and being able to play games on it are a big deal for me. Not sure what HP's offerings look like today.

Other laptops that don't appear to suck, but which I have no personal experience with, include IBM ThinkPads and some of Sony's Vaio series.
