Sure, and IPO is essentially a sale of an unpriced piece of equity. Nobody knows really how much its worth but as with earlier funding rounds various techniques try to estimate the value going out the door. That value is the combination of "price per share" * "total outstanding shares" so the total value of the company.

The company registers to sell a certain number of shares, this is additive to the total number outstanding, so once you have what will be the new total, and what you think will be the value of the company, you divide value by total and that is your price per share.

Then you go out on a 'road show' where you talk to various other banks and other investors and you say "We think the company is worth between X0$ and X1$ for these reasons and that is a share price of between $Y0 and $Y1, would you be interested in buying shares?" and they may say "Not really." or "Sure we'd love to by n shares at $Y0 and maybe n1 (often less than n) shares if it was at the high end of $Y1"

Now at some point on this road show, if you're good and the company's prospects look great, you have people who have signed up to buy all your shares, even if it comes out at the higher price. That has validated your price point, now if you haven't even talked to half your prospects you might decide to raise the offering price or increase the number of shares, you go back and call the folks who committed before and make sure they are still on board.

Now you have a list of people who are willing to buy your stock, and then when the market opens you sell them that stock at the high end price, and collect your money.

Now those people (and the bank that is the 'market maker') for the stock may be willing to sell the stock for a premium over what they paid for it. Other investors who have read the S-1 but weren't part of the initial roadshow might say "I'd buy this stock even if it was 20% higher than that initial price." and they put in a buy order for it, someone says "Hey a quick 20%! I'm down!" and sells them the stock they bought at the IPO price from LNKD.

The price bounces around and then lands at a point where nobody else is willing to buy it for any more money than it is being offered at. Nominally the 'market' price for that company.

Now if people start buying the stock for any price because they just "want in on the action." as it were, then the price can rise above the price that is supported by the fundamentals of the company, and that is a speculative price rather than a market price. Stocks priced on speculation define a bubble.

So LNKD priced at $45 I think, they had more demand than they could meet, and the price has risen. Are speculators buying it? Hard to know yet but it seems like there is some speculation going on.
Why I Made Answers.md
From white board to launch, I’ve spent 100+ hours putting together Answers.MD. It’s been a great learning experience, but I didn’t just do it for the kicks.

I did it becuase Med students deserve our support, and here’s why.

A brief outline of what it takes to become a doctor:

Take SATs
Apply for College
4 years of Pre-Med (all those hard science classes)
Take MCATs (maybe twice)
Apply for Med School
2 years of lecture (8 hours of lecture + 6-8 hours of studying)
Take Step 1 of the Board Exams
2 years of Rotations
Take Step 2 of the Board Exams
Apply for Residency
1 year of Residency
Step 3 of the Board Exams
1-3 years more of Residency
Specialist examinations
Finally, If you passed everything and got accepted to Med School and Residency programs, You are now a Practicing Doctor. (Let’s not even get into the debt you’ve just accumulated).

The Life of an aspiring doctor is one of perpetual studying and test taking. This isn’t necessarily a bad thing considering the responsibilities a Doctor has.

For a profession that is so focused on learning and acquiring new skills, you would think there would be amazing tools to help make the life of a student a little easier.

Sadly, you’d be mistaken.

Between recycled lecture notes and $100+ textbooks, students have few resources for outside support. Wikipedia has become the defacto resource of Med Students across the country.

Answers.Md Is my attempt to make the painful process of becoming a doctor a little less excruciating. And, as a question and answer site, it may not be the best solution, but it’s a start.

Have any ideas on how to help Med Students?, or ideas on how to improve answers.md? Send me an email at help@answers.md, and let’s figure out how to make Med Students’ lives a little less hellish.

They left a lot of money on the table.
Sometimes papers considering something harmful are harmful. De-duping is an obvious optimization that preserves the normal semantics of disks. ZFS and FFS assume particular properties of rotating media which aren't true of flash or other formats. The answer is not to make flash behave more like rotating disks.

In this case, they assume that blocks written to very different sector numbers fail independently. FFS writes its superblock every million sectors or so across the whole disk, assuming they will end up on different radial positions or platters so that a head crash won't get both. That hasn't been a valid assumption in a long time.

copy-on-write pages, which are a great idea. I don't think there's ever been anything implemented for DRAM controllers, because they work on bus-sized chunks that are too small.
Why not? Given that you don't need a big publishing house, there's still room in the business for folks who are experts in taking a written piece and putting it into the ebook retailers, plus promoting it. A lot of authors want to write, not deal with selling. An agent could do this for a few dozen authors and have a perfectly valid business, with happy customers.
The swerving left and right actually does not keep their tires warm, especially at those lower speeds since they aren't generating enough downforce. What it can do is communicate to the driver what the tires can do right now and provide the confidence when they need it. Accelerating/braking is how they generally put heat into the tires.
In the page hvs linked to above there's a cheat sheet version:

7% of the total IPO issuance goes to the bankers. This number is consistent across the street. Once upon a time, anti-collusion investigations were threatened because there was no explanation for why every major bank charges exactly 7%
And just to be clear, an incredibly easy ballpark valuation would be to just take the midpoints of the rev / cost growth and go 3 years out... which gives $1.3B revenue on $1.1B costs = $200M profit. A slightly high market multiple on that (18) would still be only $3.6B. And there will be dilution, selling pressure from insiders whose lockup periods will be ending, lumpiness in the numbers... I certainly would not buy LNKD valued at $8B.

But... I will say that I would be encouraged if I were a shareholder by this:

'The company' chief executive officer, Jeffrey Weiner, said in an interview that he wasn't placing much importance on how his company's stock performed on its first day. Mr. Weiner's stake in the company is now worth more than $200 million.

"To be honest with you, I didn't give a lot of thought to what the opening would be like," Mr. Weiner said. "This isn't necessarily indicative of anything. The market will do what it will do. What we are completely focused on is our long-term plans and our fundamentals, and getting that right."'

Ask HN: Do Amazon own all of my apps now?
Just after the Amazon AppStore launched I decided to test the waters with a free version of one of my apps. The app has done fairly well on the Android Market so far, but I perhaps misjudged the type of users attracted to the Amazon AppStore. The app is immature to say the least, and hasn't gone down very well with Amazon users thus far. But that didn't matter since my main aim was to test out how the Amazon store worked, and whether or not I would use it in the future.

So today I decided to remove my app, since it isn't doing well there and reflects poorly on my work going forward. I contacted Amazon through their help system and asked for the app to be removed. I received a response informing me that the app must be removed from all other similar stores in order for them to remove it from theirs.

I'll post the full email if someone wants to take a look at it, but they pointed me to section 3.a. of the developer agreement:

3.a. Delivery Commitment for Apps. You will deliver electronically to us and continue to make available during the Term all versions of all software applications, games or other digital products (including any special or collector’s editions) (i) that are designed for the Platform, (ii) for which you have the rights required under this Agreement, and (iii) that are the same versions and editions (except as otherwise provided in this Agreement) that you or your affiliates make available directly or indirectly to any Similar Service....

This reads to me like Amazon want all my apps, and won't let me remove them from their store unless I remove them from everywhere! Am I reading this wrong? Or have Amazon laid claim to all the Android apps I've made or ever will make as long as I maintain an account on their AppStore? I'm happy to terminate the contract, which appears to invalidate this clause, but I had hoped to use the store for more useful applications better targeted at the Amazon market in the future so would rather not if I do not have to. But this agreement reads to me as very heavy handed.

Any advice?

Top Reasons to Not be a Lean Startup
I'd like to support the author - is it possible to purchase this book and read it on Kindle?
I don't think the last race did the DRS right, but the first few races used the DRS better. The point is the DRS should bring a driver almost along side, so if you have the advantage in terms of grip, you'd be able to pass. Before the DRS, you can be catching a car 1+ seconds a lap, but can't get close enough because you start hitting the turbulent air from the car in front. The whole point is to get rid of this problem without making passing too easy.
Thus we see the gross and bizarre interaction of "Leaky Abstractions" and "Optimizations (read: Lying)".

Another wonderful example of this is memory overcommitting and the OOM-killer on Linux, or the entire drama of disk caches vs power failures in just about every modern desktop and server OS, or how compiler optimizations interact with both undefined behavior and each other (especially when writing multithreaded code). My point is that this is neither new nor all that surprising.

The general solution is to provide a switch to turn off the worst of the lying. I wonder how long it will take to standardize such a switch for this behavior.
All the ludicrous claims about transforming commerce, toppling governments, etc. are starting to grate a little, and I thought this headline deliberately suggested a much more serious scenario than somebody going to speak at a tech conference in the Summer.
... and remember guys, the stock price is just what the public is willing to pay for it, and is not directly bound by any fundamentals. It's not LinkedIn's fault that their stock is overvalued.
Exactly. vi4life!
Not really, the car behind still needs to get in the one second window to have the advantage of DRS.

They still need to tweak it so that passing isn't too easy but thats just a case of trial and error, they'll get it right eventually. If you compare this with last year (and particularly 2009) when cars could be up to three seconds a lap faster but still not be able to pass the car in front, it was obvious that something needed to be done.

If you care about your data so much that you need three copies of it, just get three disks. I do this for my home directory; three 1TB disks in RAID-1. If I can afford it for my pr0n collection, you can afford it for your critical production database.

In the mean time, consumer SSDs are optimized for booting Windows again and again. That's all. (apt-get upgrade is also pretty fast.)
Because they are offering little real value (the vast majority of value publishers really offered was the advance, which I haven't heard of these guys offering, and distribution which you can do as well yourself thanks to Kindle + Nook stores).

The one MAJOR cost left to self publishing if you are truly serious is editing, unless you are in a genre where stock image covers won't cut it. Giving up a % of sales revenue for the rest of time for a book considering the limited help they really offer these days is just silly.

To be honest, Barrichello isn't someone you should pay that much attention to on such topics. I think he's the only F1 driver that still uses his right foot for braking when it's proven that left foot braking provides a clear advantage.

Also, F1 highly depends on passive safety systems instead of ones that require driver input, because when things go wrong, there usually isn't much a driver can do to fix it anyways.
So? All disks lie to the controller. Have you ever had a spinning disk with a bad sector? When the disk controller notices this, it remaps the sector to some spare space elsewhere on the drive. It doesn't ask the OS if this is OK, it Just Fucking Does It.

Abstraction means that things lie to you. It also means that spinning disks can last longer than a month.

Thank you for this clarification! That was not the case in 2002-2004 (when I was a hiring manager at MSFT).
We need some sort of Big-O notation for security.

It seems like the argument against security through obscurity is similar to the argument that T(n) = 10,000n^2 is equivalent to T(n) = 10n^2, as both are O(n^2) even though they have vastly different coefficients.

At the end of the day, they have the same Big-O notation, but one of them is a thousand times better than the other.

Sometimes the coefficients matter. Obscurity in security is like the 'lost' coefficient in Big-O notation: it's not the first thing you should focus on, but it can really help.

I'm not shouting 'bubble'. 1995 was not a bubble. Even given their record-breaking IPO pop, Netscape may have been underhyped at that time – given all that was to come, and despite how things ultimately turned out for 'Mosaic Communications Corporation'.

So one potential lesson from parallels to the NSCP 1995 IPO is that there may be 4-5 exciting years ahead.
There was speculation that the call was related to Schumacher's use of the DRS. We'll probably never know for sure.

Just FYI, the lens used in each of the shots are different. The F1 shot uses a wider angled lens which makes the car look faster in the background of the shot.

Having said that, the F1 car is still substantially faster especially through a high speed corner like Eau Rouge.
There's nowhere I say that "starting a company is the best thing in the world to do." I describe it as an efficient but intrinsically painful way to solve the money problem.

"Imagine the stress of working for the Post Office for fifty years. In a startup you compress all this stress into three or four years. You do tend to get a certain bulk discount if you buy the economy-size pain, but you can't evade the fundamental conservation law."

And far from trying to draw people out of school, we actually have a bias in the other direction. We're very reluctant to fund students unless they seem like they already want to quit.
The tacit assumption upon which this argument rests is that the trolls are guaranteed to lose in court (at least after an appeal). While that might be a fair assumption in the most egregious cases, in many circumstances the lower court will not be particularly skilled in patent law and an appeal to a specialized appeals court is by no means certain. A rational businessman might well chose to settle a case even if the probability of losing is just 5% simply because the penalties for patent infringement are so high in comparison to the settlement costs.
This is pretty interesting. It's an attempt by the elite to create a differentiated online learning market, where a differentiated market simply isn't necessary. I'm so looking forward to this being made to look foolish.
X-Prize offers $10 million for mobile medical diagnostic app
While that is true, notice Amazon didn't mention the revenue from Kindle books, just the units sold. The majority of those Kindle sales could be from $0.99 bargain books. In a way that would be even better for Amazon because it means the Kindle is complimenting rather than cannibalizing its dead tree sales. Either way, it's a little early to believe Amazon is getting more revenue or profit from Kindle books than from dead tree books.

Also, running the Kindle store has placed a burden on Amazon it didn't have with dead tree sales. If the Kindle Store is anything like the iOS App Store, free books outsell paid books by 6-to-1 or more. So Amazon has to pay the digital distribution costs for a lot of books that bring in zero revenue. That adds up and can chip away the profit it makes on non-free books.
I'm just curious, why do you believe your idea will work for the market? I'm always interested in how people approach market research.
MeeGo 1.2 Released
Tempurpedic. With that said let me add my story.

I'm a 30 year old male, and consider myself in good shape. We had a generic $600 mattress before we got our expensive tempurpedic and I had constant back pain after a few years of sleeping on it, often times I found myself waking up at 2-3AM to head down to our couch for the rest of the night because my back hurt so much. The nights I did make it through the night in the bed I could barely walk in the morning because my back was so far out of alignment.

In comes the Tempurpedic and pillows... After the first nights sleep on the new bed %90 of the pain was gone.. by the second night I felt like a new person, no pain to be found. Since then I have yet to have any back pain.

The tempurpedic's are expensive, but when you consider what most people spend on a car relative to what they spend on a bed they are nothing, and besides they improve quality of life far more then any car could. You only get one set of joints and muscles in your life, treat them right.

Actually, you can lend Kindle books. Paying cash is a "freedom" consumers give up willingly in every area of life. Why can't you keep a Kindle book as long as you want? Bit rot?

I might add that consumers also give up the freedom to cut down trees to make paper, wait for physical delivery, have piles of books clutter up the house and periodically haul them away. I think they actually are aware of these.
Intel admits Apple 'helps shape' its roadmap
This is nothing more than a legalized pyramid scheme.

The valuation of LinkedIn has nothing whatsoever to do with the business, its performance, future potential or current assets.

It has everything to do with demand for its stock being high.

At some point, the fad will die and a whole host of small time investors will lose their shirts (or houses, life savings, retirement funds, what have you).

Like all pyramids, if you can get in now you probably will make some money, but don't ever fool yourself into thinking this has bearing whatsoever on anything but your position in the pyramid. This will come crashing down. LinkedIn is NOT a $4 Billion company. It's just a matter of when.
From a practical perspective it doesn't take away any freedom. I try to avoid buying any ebooks I can't get DRM free copies of in case the DRM scheme they use changes or goes away and requires me to purchase a new license.

Obviously I could just use the free copy to begin with but it wouldn't send any information to the people that make such books that I want more of them. Also the QA on such books can be a little light and format shifting them is a hassle I do if need be but would rather avoid.
Nessus is probably (still) the best for Linux in this field (certainly in the "free for home use" category): http://www.tenable.com/products/nessus

Lots of vendors have offerings in this area. The quality is ... variable. If you are thinking of getting into this market, then the hard part is not the scanning engine per se. The more difficult parts are:

* Keeping the policy rule set in sync with reality (changing business policy, attack and vulnerability landscape)

* Maintaining the rule set (are DSLs for non-specialists feasible? service model?)

* Interpreting and actioning the results in a timely fashion (eg http://measurablesecurity.mitre.org for some background)

* Intrusiveness (intrusive validation of a test platform requires careful change control -- is test identical to production? intrusive validation of production may lead to shot feet)

* Application, domain-related and physical security (as opposed to system security captured by this document). These things are harder to scan for automatically.
