1) It's not panicking. It's capital preservation.

2) 8% is an example from William O'Neil for large cap domestic stocks. That's his number; it's up to the investor to define their own plan. Percentage moves in lower dollar stocks are greater than higher dollar stocks. (It's easier to go from 1 to 2 than 20 to 40).

3) Calls in Technical Analysis rarely cause the stock to drop.

4) It's all part of your plan. Your original example of getting out when a stock drops a dollar is not a good one. If a stock you bought at 40 goes to 30, would you get out, or add more? What about 20? 5? You need to have a plan. That was the whole point.

5) Great question. If the stock is up 100% because the company says their worth more, should you sell? My example ($BKX) is a great example because the fundamental valuation that the banks gave us for the past 2-3 years were misleading.

6) It is a viable strategy if it produces a positive expectancy. That being said, most people can't get an edge in trading. However, you do need to have contingencies when investing.

7) That's the point I was trying to make! It's not buy and hold forever... but what's your timeline, or your price point?

8) Stocks and ETF's have different risk characteristics.

When people invest (and at this point in our discussion, I'm talking about specific stocks or focused ETFs) they are not always right. What do you do when you aren't right? Do you blindly hold on to the stock, waiting for that bounce? If you don't have a set risk management plan, then you will panic.

Similarly, what if you are very right and one of your picks doubles. Are you willing to risk all of your gains in the future or are you going to protect profits?

The whole point was to show how risk management and capital preservation is a necessity when investing (or any business venture). To deny that is a serious mistake.
War behind the scenes.

I was just wondering. I could have lived with a simple downmod - but this turns out to be more interesting (if annoying to you).

(I should have done those statistics (and a few more) about news.yc I was talking about some time ago.)
I would be a surprised if someone could pass a blind taste test and tell ceramic from aluminum or plastic for the relatively short time coffee is exposed to them.
Doing anything and waiting for some time. But I guess that's by design.
You could make "junk DNA" a fitness criterion, and kill off entities that have lot of it that way. Natural selection doesn't really penalize that, because it has no effect on survivability.

However, it might have a long-term advantage, because of evolution's randomness; if you eliminated the junk DNA you'd also have a much more directed walk through the genome's expression space, which means that you might miss a lot of very good solutions.

Interesting article, although the basic thesis is not new.

One way to view the application of machine learning to science is simply that ML automates part of the scientific method: inducing plausible hypotheses from the data.

I don't see how the author concludes that "correlation is enough" or "we don't need models": the whole point of machine learning is to develop a model that explains the available observations and is useful for predicting future observations. Just because those models are expressed mathematically and derived algorithmically doesn't mean we don't need a model at all.
What can I say? Sometimes our newsbots make mistakes.
I've used A/B and multivariate testing at multiple companies. It can be incredibly helpful in optimizing a product.

I would suggest however to focus on building a solid base product first and then optimizing it.

For web the google web optimizer works ok and its free. There is a Boston startup called Sitespect who I've used in the past as well, which has a more robust platform. I can introduce you to them if you want.

I wish there was an easy syntax (in Python) for not only map and filter - but for something like reduce/foldr/foldl as well. You still have to write loops to do this (or use reduce.)
Awesome. Now I'll know, for when I drop out of college and start a rock band.
I would love to see feedback that you have gotten from serious investors. I for one always check out "most emailed / most clicked on" stories in reuters, bloomberg, nytimes, wall street journal, etc... If other investors are reading it and I haven't then it makes me think that I'm missing out on something.
Real time traffic? Quite possibly.
Same for FF3 / Hardy Heron.
Kira doesn't look like fun to program in, but the idea of translating to PHP is interesting.
I remember when zipzoomfly.com was googlegear.com. that was before I found newegg.com.
The main problem I see with building such a community is that the people who return to it aren't the kind of people you'd want to have as cofounders. All the good candidates will form startups and get on with it and no longer have a need (or the time) for such a community.

As for a good way of finding cofounders, I can't really answer that from experience. I've done a poor job of doing that myself having not found any, but I'd rather go it alone than just team up with someone I've randomly found on the internet.

If you've got a bunch of friends who are kind of on the fence about the whole thing, either because they don't like your idea (big red flag!) or because they're not sure they want to commit to doing a startup, I recommend talking to them and forcing them to be honest with you about your idea and their plans. You could see if they'll join you after you've built some kind of proof-of-concept/prototype on your own, although I recommend you plan for the case where they never follow through with it.

If your friends just plain don't want to do the whole startup thing (that would account for 100% of my hacker friends) and you decide to go it alone, try and keep a few of them in the loop of what you're doing as much as possible. They won't replace a good cofounder, but better than nothing and will keep you grounded.

By the way, 'friend' here refers to people you have a lot of trust in, as opposed to 'acquaintances'.
I had to right-click and copy link, new tab and paste to get the printer friendly. Probably checks for a referrer.
Whatever happened to Artificial Intelligence?
MDI interfaces are so last century...
Agreed that right now its positioning is too prominent: at the row-end it's easier to see and click than other more frequently-used links. The problem is especially evident on the front page: it was rare for spam to reach there, but now it's harder to visually target every 'comments' link.

Moving 'flag' leftward on the line would help a bit. Making it only appear on the clikthrough page for an individual story or comment would help a lot -- requiring an extra click to flag something but not imposing clutter on all good contributions.

At some point anti-crime measures themselves become a community bummer. 'Flag' links everywhere are a little like walking through a neighborhood where all the windows/doorways are protected by metal bars.

What percentage of our attention is soaked up by defense? Over a certain threshold and the spamorrists have "won".
I'd be interested.

I kind of envision something like the threads page, but viewable by anyone who clicks on my profile. Additionally, I could post self-contained entries not spawned from comments.

Still 10 lines of code? ;)
something like that..., but I was really thinking of something resembling the "Best of the Worst" of the last-man-standing reality genre (American Idol, Last Comic Standing, etc). It would be good fun to occasionally look at the list of flagged posts just like it's fun to occasionally poke fun at William Heng.
IPhone/iPhone 3G side-by-side review
The comments show that the article author presents a false dichotomy. All the data collection and analysis depends on models. Then from that analysis you get new models and do new analyses. This is how science works, whether you have tons and tons of data or not.
Nokia Acquires Symbian, Takes On Google Android
I like the idea of a something-not-evil to PHP compiler, but I don't think this looks like the kind of language I had in mind. I can't help but think this is the malformed offspring of breeding ML with C#.
Yahoo going back up
This is pretty darn cool, you need to keep working on it. I would love for a search box to either search or quickly hit on the stocks I have in my list instead of relying on the side scroll buttons.
I started to respond, "...then they could be aggregated in a separate top level 'blogs' tabs and upvoted if interesting."

...but then something groovier occurred to me. What would be all kinds of cool would be an aggregation that automatically sucked in an RSS feed listed in a user's profile for all users with, say, over 100 karma. That'd be similar in spirit to the Planet Startup idea from a while back, which sadly didn't get a critical mass of feeds.

Google Ad Planner Launches, Offers Site Demographic Profiles
That's about what I've been getting recently for my game. About 40% of the clicks from the ads result in downloads of the game, then about one out of 20 of the downloader's actually end up paying for a subscription. It seems getting people to click on ads and getting people to download (especially when it's a small download) are the relatively easy parts. Getting them to create an account once they've downloaded and getting them to pay once they've tried it are much harder.
Horizontal scrolling? Really? Seems like a JavaScript guitar solo to me.

Modding MacBook Air SuperDrive to Work with Other PCs
I'm willing to share this site with people I work with and can even get it to the people on our trading desk if you give me a way of getting feedback to you. BUT, don't be surprised if people look at it for five seconds and don't care. Finance people are some of the most impatient people I've EVER met and if your design isn't appealing, they'll ignore it. I'd focus on making the information people want jump out at them as much as possible. You're filling up a lot of space at the top. Try putting some of that at the bottom. Actually, modeling your site after similar designs found in MSNBC during the day would be a GREAT step in the right direction. They're presenting info, via TV, in an already accepted format. If you could improve on that, you'd be in a good position.

Oooh, good question. I certainly don't have a definitive answer. My current preference is to have a few atomic composable methods in a vocabulary. If I find myself using a specific compositional idiom enough that it needs its own name, I create a new method and factor out that idiom. I use this strategy when writing libraries for my own use.

When distributing to others there are more concerns in play. In a language like Java where 3rd party libraries are frozen from the perspective of the developer a rich vocabulary is a helpful thing. In Ruby, open classes make it much easier for the developer to add things on their own. Lua aspires to minimalism; its standard libary is very small and atomic. Lisp is a very compositional language so I would lean towards exposing only the key concepts of a library. These are all valid approaches in their spheres.
I played with a Dash GPS for a week here in Cupertino. It's really awesome and I'm already trying to sell my Garmin Nuvi to switch to the Dash.

As for your complaints:

Social network for the highways is reporter-speak. What the Dash does is it consolidates traffic data from all the users, analyze it, and then pushes back to the users. So if car A slows down or stops because he encounters a traffic jam that data is sent out to other cars behind car A to inform them of such a problem. It then redirects them to another route as a means of saving you time. If you don't think that's freakin' awesome, well then I don't know, you must live on the moon.

Also hardware companies have a considerably higher overhead than web 2.0 companies considering the amount of R&D and manufacturing costs associated with releasing a, you know, actual product.
While it's novel that it's compiling to PHP, you're still at the mercy of PHP as a language and what it has to offer. For instance, PHP lacks a true closure so if Kira want's one it'll have to build out a full system...

C++ : C => Kira : PHP
I see the traditional record company being replaced by two sets of firms: 1) Online commission-based digital distribution firms and 2) Firms that handle tours, preferably also commission-based.

1) hasn't been done well yet. I know Amazon lets bands list and sell MP3s, and amiestreet.com offers music from indie artists with a funky pricing model. However, there's not really a "go-to" place right now with a large amount of traffic from people looking for independent music. Amazon is dominated by the majors, and no other site is very popular.

There are a number of popular places for a band to distribute their music for free, such as Myspace, but these places don't provide their bands with a revenue source. I can understand how bands would like to get paid if people love their music.

Some bands have resorted to selling their music themselves straight from their website (NIN, Radiohead, Girl Talk, etc.). However, it ought to be possible to automate this process to allow bands without technical skill to list and sell their own music (maybe make an embeddable music store?). Also, a central site off the band page could allow less popular bands to get some exposure.

Does 2) exist? I don't know. I have heard of some firms that manage tours for famous independent bands, the kind that have been around forever and have fulfilled their initial sodomizing major label deals. I don't know if any exists for mid-level bands.

One thing is for sure - the record companies are dinosaurs. They are glorified middle-men who connect bands with CD printing and distribution firms. Digital distribution means that they no longer serve a function, outside of marketing. That's the one downfall of online distribution - there are millions of bands on the internet and it is hard for fans to find new stuff they like.

There's been a number of startups that have tried to help people find new music, from the big guys like Pandora (dominated by majors), to new little guys like thefeelgood.com. I don't think anybody's gotten it right yet, and none of them mix the marketing with the monetizing well.

Honestly, if Myspace let bands sell MP3s on their profile page, it would probably be good enough and 10x better than anything currently out there.

So, what do you say Hacker News? Is anybody out there working on burying the record companies? What are your ideas, and how are you doing?

Anybody live in San Diego and want to do it with me?

Trojans exploit Mac OS X ARDAgent flaw
For what it's worth, this was how Microsoft used to compete back in the day. They would go in to a big orgs like this that used to have Novell or Lotus contracts worth tens of millions and offer up prices per seat that were ridiculously cheap.

One day, Google will feel the sting as well.

Great insight on their part - (rails memory footprint) - I wonder if it can be applied elsewhere - i.e. to mongrel.
I think it would be worthwhile as long as the things people submit still meet the existing site guidelines: no cat pictures, nothing about "I had dinner with so and so last night".

Very nice hack. I didn't realise the external MacBook Air drive was incompatible with other devices, it strikes me as another one of those unnecessary "shame on you, Apple" decisions that keep me on the fence about their products.
While true for Opera, it's rather generous to call IE6 a "competent browser."
I can't imagine wanting to convert another language to PHP, except for JavaScript maybe but that's not exactly useful. Now converting PHP to a different, more-useful language? that would be something :)
I didn't have a problem with the phrase "ton of paper". I just picked that example because I thought the two clauses of the sentence didn't fit together well and the double use of the word "paper" was jarring.

Maybe, "Gregory's cluttered bedroom contains at least a ton of paper." Or, "Gregory’s bedroom is filled with paper; it contains a literal ton of printouts, articles, and magazine clippings."

IANAW though. And I don't know what a literal ton is.
It just goes to show how compartmentalized gov't work can get. My first project there seemed more like a body shop than anything else; a few people developed the software, and the rest of us just fed it data and wondered why they bothered with such a rigorous hiring process.

Some of the projects that WOTI did sounded very cool, though. My experience was pretty disappointing, but that was three years ago, and most of the co-workers that I was friendly with while working there have moved on.
Works great here, fast and snappy.

Joel Spolsky's language Wasabi compiles down to VBScript and PHP and JavaScript.

http://www.joelonsoftware.com/items/2006/09/01b.html

Features of Wasabi:

closures, active records, lambdas, embedded SQL a la LINQ

Wasabi is 100% backwards-compatible with VBScript but includes obvious improvements.
I agree with this. At the moment the "flag" link, which you want to use very rarely, is more prominent than the "comments" link, which you want to use often. Maybe changing the colours to make "comments" dark and "flag" light might work as well.
Thanks for submitting! I'd like to clarify the title of the submission and say that these videos are from Shmoocon hacker convention 2006, 2007 and 2008.

Ultimate Physical Limits of Computation
Good point. I know IE6 still has a decent user-base but I really felt I shouldn't spend the enormous amount of time necessary to make this site work with it. IE8 is due out soon and for web developers to continue supporting IE6 is the reason why its still around. I only wish more people would stop supporting it. Opera on the other hand is a great browser but I can't get jQuery to work correctly with it at all. And thats out of my hands in a way.
> If your developing web applications its completely possible to be self-taught and produce high quality applications.

it's all ones and zeros, how hard can it be ?
i, just press the right key at the right time, and the program practically writes itself (with apologies to beethoven).
Can you make it so that user's first click on the 'flag' link would bring up a short explanation of what the 'flag' does ?

I'm sure a lot of people are going to be clicking on it just because it is there. I know I would've if I hadn't ran into this thread first :)

(edit) Would it make sense to display current flag count ? Perhaps if it's over certain threshold. It is after all an interesting metric.
what happens if you pull on the side of the road to change your tire?
I can see all the hangers-on trying to skin bands, since they can vanish in an instant, but you'd think that companies would want to cultivate groups. Give them a free-and-clear 75 cents per album or whatever. How hard is that? And then if they become big, they won't jump ship out of hatred.

Apple sold 6 Mio. iPhones till June and the whole smartphone market is about 300 mio. phones, that's 2%.

The percentages mentioned on Techcrunch and all the other blogs mention selling figures per quarter. e.g. 35,522,360 smartphones sold in Q4 and 2,320,840 iPhones that means only 6,5% in this quarter and not in the whole market.
I think it was 26% in Q1 2008 and 19% in Q2 2008 but as you see their market share is still only approximately 2% of all smartphones.
It's not the content, it's the delivery.
Bought from them as well for 10 years. Never had a bad stick.
Depends. If only one in every ten thousand cars has it, then it's not very useful. If one in every four cars has it, then you're getting a lot of useful information about traffic.
That brings up a pretty valid point - has anyone broken down what happens with what level of karma?

I know at 5 you can downvote comments, and at 250 you can change your bar color. Somewhere in there, you can create polls, but I don't know how that works, so I don't know what level karma is needed.
I also cannot figure that out but it seems amazing, too. Anyone, knows what this is (and artists' name)?
Voting's a pretty big one. I'll own up to the fact that I often use votes as more of a bookmarking tool, to follow up on promising links later when I have more time. As a result, I get the urge to unvote something every once in a long while when I realize that it doesn't deserve good karma.

Although if the intent is to discourage that usage pattern and make people more careful about voting in the first place, then it works, at least in my case. I use votes as bookmarks much more extensively on digg, where I know I can undo them.
I'm pretty sure I could downvote from 25. Maybe it was originally 5. (seeing as I joined much later than you)

I'm at 408, and I can't see a way to start polls, so I'm guessing that's at 500.
Can you add an option for disabling flagging? I probably won't use the option that often (maybe once every few days if not more), so I'd like to hide it until I need it. Too much clutter.
It parses the data intelligently by including actual traffic info from other sources. As more users get connected it's more accurate at determining deadlocks without the aid of other sources.

Also, wouldn't it be awesome for it to know where I am at the side of the read and beam that info to AAA?
I test everything, headlines, images, buttons, etc. If you want to know what your users want, you can test your way there. Your users will tell you. Especially useful for e-commerce and lead generation sites. If you can increase conversions from 1% to 2%, you've just doubled your revenue. Google website optimizer works well for me.
Are those US or global figures?
Can you please allow us to see more entries in the 'threads' page? (perhaps with a 'more' link)

Yup HN Blog Platform would be cool.
