gizmo, you and the other guys (and girls) on here are all over the exact studies and discussions we had internally with respect to this product - i appreciate the discussion. Pricing and positioning this and future aspects of our business model has been my focus for the past 8 months.

The value of Xobni is built on two pillars: search and relationship management. This offering builds on that first pillar. Future offerings will build on the other pillar. We actually priced this offering below what we think was the optimal ARPU (average revenue per user). We did that for 3 reasons (1) we want a huge % of users on this paid product - upselling to future offerings will be one-click easy (2) we believe paying users are more evangelical (humans justify decisions they've already made) (3) as a business in our stage we believe it is less risky to monetize a larger user group at a lower ARPU than very few users at a higher ARPU

We are optimizing for the 2-5 year revenue scenario (not 6 month scenario) - in the not too distant future Xobni will be launching an enterprise offering, a blackberry application, and other premium offerings. I've been waiting a long time for this stage of building the business.
I can't think of one non-procedural language you can "teach yourself" by writing a compiler for. That was my point of reference.

Even if you don't do any semantic modeling of the language itself, you most likely will be reading similar research done for a similar language.

You can teach yourself an Algol dialect by implementing it first (same thing with Forth) but that's pretty much about it. Even Griswold's Icon, procedural at it's, is more sophisticated than anything Algolish.
I can only see the summary report in the demo.

Mainly, though, each b+-tree node is the same size as a disk I/O block. The disk is often the slowest part of the database, so making as few reads as possible will go a long way. If you can't work entirely in memory, that's the next best thing.

That makes no sense. An external hash index is also designed to do as few I/Os per read as well (typically just a single I/O to read the page that holds the target bucket). Just like b-trees are designed differently than in-memory trees, external hash indexes are designed differently than in-memory hash tables.
My Laser 128 can't read floppies ever since the magic smoke came out of it. Wonder if I could fix it.
It might be a interesting idea options other then subscription.

For example, many someone might want to use this to audit a site. You need a data collection period (maybe collect data on x visits and then stop) then access to the analysis tools.

You could price that as a one off package.
How to tap the wisdom of the crowd in your head
As opposed to a guess based on ignorance.

Nobody is arguing for ignorance. That's not an argument made in either the original post or in mine. The thesis is that what people call planning is usually guessing and should be treated as such, not that making informed decisions is bad, not that guessing is bad, and not that planning is bad.

You say planning is preparation, but preparation for what? You are necessarily making predictions about what will happen in the future and what the appropriate course of action will be. The ideas are inseparable. Again: not that this is bad, but it is still guesswork--still map, not territory--and should be de-emphasized relative to dealing with the territory itself.

How much you devote to it depends on the costs associated with speculating on a course of action. Is this time spent planning going to save more time of work? Are the consequences of these possible situations worth the effort expended to prepare for them? If you're (say) coordinating hundreds of thousands of people to invade Europe, the cost of speculating and preparing is dwarfed by the cost of changing course to react to new developments. On the other end, especially when it's an individual or a small business, sometimes the cost of speculating on a course of action is higher than the cost of just putting it into practice.
It's official: micheal arrington is the perez hilton of the tech world.

But seriously, how is this in any way legal? I almost can't believe it, it seems like a hoax...
I'm strongly of the opinion that they shouldn't post them... Just seems like bad karma at the least or a potential legal problem at the worst.
Ask them questions. I've used Twitter for everything from finding good bars in Bristol to getting someone to take a photo of the front door to a cold war bunker (twitpicced to me within 20 mins of the request for a picture).
A hash table isn't much use for queries that return multiple rows, or use aggregate functions.

Neither of those claims is true. A hash index is perfectly useful for queries that return multiple rows: the index just stores all the duplicate values for the search predicate in the matching hash bucket. And hash indexes can certainly be used with aggregate functions: you first use the hash index to evaluate the query predicate (WHERE clause), and then you evaluate the aggregation or grouping clause over the results of the hash index.

it may be somewhat unethical, but its legal. If you couldn't write about anything "confidential" the news companies would be out of business.
I don't know if this is the case here, but often in benchmarking, "min" is the real answer of how fast something is going, and any time on top of that is some kind of overhead that you weren't trying to measure — some other process was taking up CPU time, you had to page in part of libc, crap like that. "avg" serves to tell you whether that overhead was reasonably small, or whether you need to run your tests again (on a quieter machine, say) to get a smaller "min".

This depends on the assumption that what you're measuring is actually a deterministic process. There are cases where it's not; as an example, the Self papers have all kinds of moaning about the measurement imprecision caused by physically-mapped direct-mapped caches without OS page coloring, but with more than one page of cache, on old SPARCs. For any particular logical→physical mapping, your measurements would be reproducible, but when it changed (if you got paged out and back in, or if you restarted the virtual machine in a new process) you would get different results.
Thanks for the rationale. I hope it all works out.

Not necessarily true; linear hashing avoids this requirement, for example. http://en.wikipedia.org/wiki/Linear_hashing
It's not apparent to me from the writeup -- does the Google Voice client make its calls using the cellular phone / POTS network, or is it VOIP and just using the cell network to pass packets?

I'm assuming SIP is probably a non-starter with the US cell companies, although it doesn't stop it from working fine on the Nokia S60 platform using the built-in dialer and client.
Posting this is in techcrunch's best interests. It'll get them a ton of traffic. I'm sure they'll milk it for a 5-6 posts. Then a few weeks down the road, someone will do the same thing to them, and they'll do another 2-3 posts with outrage that their privacy and confidential information was violated.

I'm sure they'll keep all the juicy stuff hidden. Since they are working with twitter on what they will/won't release. Although its kinda stupid, considering the stuff will show up on other websites
I think particularly there's a lot of merit in the suggestion "to distribute intellectual property free in order to sell services and relationships". But how to manage that profitably remains the tough question.

I've heard that music artists increasingly make more money from concerts etc than through their music, which is so readily copied / stolen. My business is very mindful of the value of our intellectual property (business frameworks to aid growth), but ultimately my clients pay mostly for their relationship with me / my team. Would giving away IP help attract more clients, or would it create competitors who would then undercut my relationships by competing on price?

Wouldnt the unethical thing be sitting there reading through a bunch of documents you know were illegally obtained? Then following it up by basically bragging about it..

TechCrunch is not what it used to be :(
You could also do A/B tests on pricing and pricing model. Like currently on Wingify, we are testing what text elicits better responses: "Free Private Beta" v/s "Exclusive Beta" or "Signup for Beta"
I'm not a lawyer but this says it's going to publish entire documents which supposedly are private, what it's illegal. This is just marketing and not true (the entire thing).

So do they hacked the entire computer network of Twitter offices just for the shake of sending the documents to Michael Arrington?

Are you serious?
Madonna lookalike is actually a man 
This Madonna lookalike may look convincing, but he's actually a man.
The scary part is that TechCrunch isn't the only place these documents will land up at. Other recipients of these documents won't be so scrupulous about not posting sensitive information. I imagine Twitter is going through a lot of hassle around resetting security codes, reaching out to interview candidates, employees taking measures to protect identity theft, etc. Just a nightmare.

The other scary scenario is that this "hacker croll" has more documents which he hasn't shared yet. When the original HL2 code was stolen from Valve, Gabe Newell was contacted later with additional documents (which lead to that person getting arrested)
It makes the calls using the cellular voice network but it uses the data connection for text messages. At least it did in before I'll check it out first thing tomorrow and report back.

Is it "should"? I don't like that word. Are there other options?
Initially, I was shocked that they would post the stolen information. Eventually I realized that this is going to be publicly available regardless of whether Techcrunch posts it or not. The information would be released elsewhere. As a news site, they are unable to ignore its existence.

Techcrunch has discussed this with Twitter. They have also decided not to release private information. From this I can say that they are being fair about this.

This does suck for Twitter. Though, it does bring to light the potential dangers of using a web service to host your confidential documents.

"the original security hole seems to be Google, via Google Apps for your Domain. Some passwords were guessed and things started to fall apart from there. Most (or all) of these documents were downloaded from Google’s servers."
I find this an interesting take on the subject. I'd use the same line of thought to argue for the opposite position: it's a good thing if a statement could be proven to be wrong! Arguments that rely on a set of empirical claims of superiority are good arguments, because they can be tested. Statements that are not refutable -- such as statements about the superiority of a subjective moral -- are bad arguments.

For the record: Here's one Open Source advocate who applauds LinuxCare for saving themselves by abandoning Open Source. I guess, the current users of LinuxCare's products probably agree. Yes, I advocate for "proprietary development methodologies in areas where evidence seems to show that they are more effective".

An idea is not inevitably good just because it's guided by principle.

In fact, I believe most ideas that are guided by principles -- especially those that claim moral superiority of a certain principle -- seem to turned always into human tragedies.

CERN Stress-Testing Large Hadron Collider, Everyone Hide Under a Chair - Gearlog
This is a good article!

What does HN think about the term "patent pirates" for these people? Like maritime pirates, they use threats to extort money from people engaged in legitimate businesses, while carrying out no productive activity of their own.

I think that in the next few years, the markets for patents he describes will make the US a substantially worse place to try to carry out innovation or sell an innovative product. They're pretty much inevitable, because the economic value of a patent held by a patent pirate is much greater than the economic value of a patent held by a productive enterprise that is vulnerable to a patent countersuit.

If you store your corporate documents on other peoples servers you deserve what you get. What were they thinking ?

Confidential stuff should not leave the building, let alone be uploaded to 3rd party data centers. Keep in mind that just about anybody with sysadmin privileges at the company hosting your data also has access to all those documents.

As does anybody on the wire between you and the host during up or download.

Now let's hope somebody posts some of techcrunchs' internal and confidential documents. What goes around comes around.

I wonder if he would see it as "news" if someone posted all of TechCrunch's private internal documents?
He actually replied in the comments to something just like this. He said "no" of course :)
I would argue it brings to light the dangers of not having secure passwords, this applies to local networks and servers, not just web services.
say Zed released Mongrel under a BSD-license, then any big company (or any person really) could come in and modify it, make it better and then sell it. And Zed would be left with nothing.
That's what GPL is for, adjusting it is fine, but you can't make money out of a redistributed modified version.
Samsung C3060R
Samsung has always been famous for introducing mobile communication devices that are one of a kind. The phones by Samsung are technologically advanced and all other aspects of a modern consumer are kept in mind. The phones are also stylish keeping in mind a modern fashionable consumer’s choice in mind. The Samsung C3060 is a great way to celebrate the wedding of style with ultra modern technology. This phone comes equipped with some of the best mobile communication features. The look of this mobile phone is sheek.

Quite, indeed. These pussyboy designers need to go shoot themselves. It's bad enough @font-face exists now, but to tout its virtues on a completely unreadable website? Come the fuck ON.
So, you're crawling HN and you expect the target of your crawl to fix something so you have an easier time of it :) ?
Hash algorithms are prone to collision depending on data/content you are storing. If the data is similar then it can lead to collision in hash keys, which can deny O(1) retrieval. Retrieval depends on content stored and O(1) can not be guaranteed every time. One of the reasons for going for binary tree based traversal is guaranteed O(log n) irrespective of the kind of data that is stored.

The salt value is public. You don't have to brute force it. This isn't a "rainbow table"; it's exhausting the secret input to the hash function itself. Your analysis is broken.
Do you exclude traffic and clicks received from HN ?
My wife had a mac from that era and it was toast. I got it running again with a logic board from the same model which I found in the back room of weird stuff for $20. I love that back room. We got the data off and now I have the data backed up like crazy.

Weird stuff is -the- place to find old hardware.
A couple other things to consider:

1. Create a multi-column index that satisfies the query entirely on its own without the need to go to the table to read additional data. This technique solves a large percentage of slow query problems.

2. A bitmap index in Oracle kills concurrency. Do not use bitmap indexes for table with multiple concurrent transactions.
I weakly agree with you, but consider a few counterexamples. Were Bernstein and Woodward wrong to publish information they received from Deep Throat about Watergate? If someone were to leak confidential info on the Bush administration's role in Guantanamo Bay, should the press publish that? How about Microsoft's Halloween memo? Was that fair game?

There's a line somewhere. Twitter's financial position somehow seems different than Watergate. I'm kinda curious where you think the line is. It's not a universal "journalists should never publish confidential information", because in many cases, it's very important for the public to know.
Apart from rudimentary key bindings, the two features I immediately miss whenever I use another editor are query-replace-regexp and dabbrev-expand. Oh and display-time also earns honorable mention.
I must admit, I am not quite sure what his problem is. Surely if he would want a consulting job, he would have no problem to get one, with Mongrel as a reference?

I remember he used to rant about something like not getting a job, but he can't have been serious? Maybe he is asking 1000$/hour, or his ego really makes him unemployable (which I doubt). But even back in the "big rant day" I think there was a footnote somewhere where he said he basically was fine and didn't need a job.

Maybe without Mongrel, nobody would listen to his rants to begin with. (I guess he did lots of other awesome stuff, but I only know him for Mongrel).
Gmail adds to-do list feature
Eh, I interviewed, but it was before I joined my current employer. Unless the interviews are date-stamped or you've been at your job for longer than Twitter's been funded, I don't really see much of a problem.
Facebook continues to ruin productivity.
Not everybody who uses Mongrel is a multimillion-dollar company.

Maybe if it wasn't free, nobody would be using Rails and Mongrel - everybody would be on C# and Mono. There is always competition, so "should be rewarded" is really determined by the market. You can't just work on anything and then demand money for it.

Mongrel that costs money would be a different product from Mongrel that is free.
An interview with Carver Mead (2002)
Arrington says the vulnerability was in Google Apps for Your Domain, although the original article about the hack says otherwise:

http://www.pcworld.com/businesscenter/article/164182/hacker_...

Hacker Croll claimed to have accessed Goldman's Twitter
password by first gaining access to his Yahoo account.
"One of the admins has a yahoo account, i've reset the
password by answering to the secret question. Then, in
the mailbox, i have found her [sic] twitter password,"
Hacker Croll said Wednesday in a posting to an online
discussion forum. "I've used social engineering only,
no exploit, no xss vulnerability, no backdoor, no sql
injection."

I wonder why the hacker would send the documents to Techchrunch. He could have uploaded them somewhere and then submitted the link to Reddit.
You can sell GPLed software, Linux distributors did it for years.

Although I know it's petty of me, for some reason that smarmy grin photo of his really gets on my nerves, even the smaller version that normally appears on his blog.

I'd probably read and think more about what Greg writes if he found some other mugshot or just ditched that picture entirely.
So if I use Linux in my corporation, I am supposed to mail around thousands of T-Shirts now? You know, maybe a Microsoft stack would come in cheaper in the long run.

Conceded that technically OpenSSL is much better off than BIND ever was. When I was a lay-sysadmin many years ago, I ran BIND because what else was there? but always in the back of my head was the possibility that someone found Yet Another Hole in BIND. I'm not nearly as concerned about the implementation quality of OpenSSL today; it's been long enough it's probably okay (but at the wrong level of abstraction). But it historically had enough issues to show up on my warning radar as a lay sysadmin, and that meant that I never really trusted it afterward.

Could be complete paranoia at this point.

Now that we know who Deep Throat was, Woodward and Bernstein are no longer quite the shining example of capital-J Journalism that they remain in the field's hagiography.

They were spoon-fed all their information by the acting head of the FBI -- the free press didn't oust Nixon, the powers that be did.

Don't forget that the anonymous sources are steering the story, and that their agenda is often more interesting than the actual information.
I don't think I've ever seen "swag" used. Are you implying that "swag" means trade show stuff while "schwag" is drugs? I've always seen schwag as the term used for trade show stuff, and I was unaware of the drug connotation. Google and Wikipedia seem to agree that it is an acceptable spelling (and they also agree with you that it can mean drugs).

"Swag", on the other hand, doesn't seem to mean what you think it means.
