just out of curiosity, what do you think of the criticism that finance students tend to learn too much theory?

When I was doing a project for a hedge fund, I showed an MBA student my analysis (financial model + write up on a bank) and this is a person that also majored in finance at the college level and could not understand any of the work.

It was pretty interesting. I never knew there was such a divergence. I ended up teaching myself finance (liberal arts major) so I just learned by going to the library and pouring over finance and accounting books.

I actually tell a lot of people that if they are interested in doing real good analyst work they are probably better off majoring in accounting because the finance end is easier to pick up outside of school.

I think his decision may be related to his favorite economic indicator: freight transportation. In an interview with ABC, Buffet said that the Freight Transportation Service Index was one of his top indicators of how the economy was doing: http://cosmos.bcst.yahoo.com/up/player/popup/?rn=3906861&...

Watching the flow of raw materials and manufactures around the country is probably a better indicator of economic health than looking at the speculators pump up the Dow.

I think "having a problem, not sure what just yet" is a perfectly acceptable thing to say.
I agree. There is certainly far less hassle going between Firefox 2.0 and Firefox 3.5 than there is between IE6 and IE7 or IE8. That said, this is not really the substance of the article or the article's headline. The headline and the comparison don't really make much sense, unless you're basically trying to promote Firefox. Don't get me wrong, I'm a Firefox user and evangelist. But making flimsy comparisons isn't what got us here and it doesn't really help us think about the state of the web.
Possibly valid. Venture-backed companies do sometimes evolve successfully, but I can see how your theory could have played out that way, though.
You're purposely misreading him too. He never said "junkyard". If he wanted to avoid the authorities, I'm sure he could find somewhere to do it, and probably living in a reasonable environment too.

Magnetos are less reliable than most other parts of an aircraft engine. I'm a relatively low-time private pilot and I've seen mag failures more than once in aircraft I've been in. That's one reason aircraft engines have two of them. You can continue flying with only one but you won't quite as much get as much power and if the other goes you'll have to land promptly using gravity instead of engine power.
I like the idea of electronic ignition.
Slightly unrelated, but here's a video I made of a simulated engine-out (autorotation) landing in a helicopter: http://www.youtube.com/watch?v=pzWw5U3eCok

I've worked places that had that setup with BGP. Of course, you need to announce the same IP block out of both data centers, your application needs to be able to deal with that, and that sort of thing gets pricy, but it's doable.
I noticed that too. What if the source is something that can't be shrunk?
Bitching about it accomplishes nothing. I doubt there's anybody here who thinks this is a good thing, and even if there were, that sort of language persuades nobody.
The smart thing to do is to write your congressman, and get people together to protest.
Anybody here have any experience with politics and know what we could do to stop this?
to be clear, the above is meant as the lesson to the customer, not rackspace. It would be very nearly impossible for rackspace to make their virtual servers stay up if a whole data center went down. It's quite difficult to keep a VPS up when even just the hardware it is on goes down.
The mechanism is wide open for abuse. If this regime comes to pass, I would expect different groups to be issuing bogus takedown notices against competitors...

Imagine if PETA activists started nailing the public IP's of meatpacking companies with allegations of copyright infringement...

It's interesting that AT&T isn't disputing the lack of 3G coverage claim. Instead, they're stretching to say Verizon was implying something else with clearly-labeled maps.

Pretty inane. I doubt they'll win. It reflects pretty badly on them, too.
Then what? It's better than complaining on a website where everybody agrees with you. I'm going to do something. We've got to do something. The situation's bad enough as it is.

I don't know. We're probably fucked.

If you believe you can stop this by writing to your congressperson or protesting: why do you think this is being done in secrecy? Obviously, they are fully aware nobody is going to like it. It will be enacted regardless.

That being said, I would still like to do as much as I can to prevent it, or in the case that it's enacted, circumvent it or corrupt it to the point of uselessness. At this stage, I don't think there's much we can do just yet. We also can't be sure this report is accurate.
We find a silly case under this law that would've been legal previously, then get a few hundred thousand (or more) people to download it, willingly putting the content up in violation all at once. Civil disobedience isn't the best choice necessarily, but it can work quite well in situations like this.
The problem is not companies that are "profit mongering" (whatever that means). It's companies with obsolete business models that are willing to destroy the more dynamic parts of the economy in their fall.
replace threshold with parameter,

classifiers may have different parameters other than threshold

Area under ROC curves (AUC) are used to evaluate how good the model is considering many parameters can be chosen for it.

However, when you actually want to make a prediction, you still need to pick a value for the parameter (a point on the ROC curve). So F-measure is often more useful for evaluating the predictions. While AUC are more useful at evaluating classifiers.

I received this email an hour back from Rackspace:

At approximately 12:29am CST this morning, our Dallas - Fort Worth (DFW) data center experienced a power disruption, and consequently an interruption of our services. The power disruption was the result of issues during a maintenance effort that was scheduled and expected to be non-impacting.

This summer our DFW facility had power issues, and as a result, we invested significant resources to improve all aspects of our power systems. Last night, during one of these steps, we encountered issues and had a brief loss in power. The power disruption was approximately 5 minutes in duration. Despite this short power disruption, many customers experienced downtime that was significantly longer. Since the power disruption hit the core of many of our cloud services, recovery of full operations required more effort than simple recovery of power. The experience you had last night is not acceptable to us.

Here is what we know about the events:

· The scheduled maintenance was planned to occur from 12:05am - 6:05am CST in our DFW data center. This maintenance is part of a preventative maintenance schedule for several PDUs in UPS Cluster G at the DFW datacenter. The PDUs were down for a total of 5 minutes before power was restored. At approximately 12:29am CST, all PDUs behind UPS Cluster G lost power.

· Although the power outage was very brief (5 minutes), it forced a hard re-boot to occur on a portion of our cloud infrastructure. As our engineers worked to bring hardware back online, we experienced several unforeseen hardware failures. Further complicating our recovery effort, the incident also created internal DNS issues, which caused additional delays. With that said, the vast majority of cloud customers affected by this outage had service restored within one hour's time (many in as little as five minutes); however, depending upon the service, a few customers experienced service interruptions for up to few hours.

Here is how we plan to deal with it:

· We have invested massively in the DFW facility to ensure it delivers at a level you expect from Rackspace - despite last night, we feel very good about our plan and have high confidence in the DFW facility - clearly we have to prove it.

· We are reviewing our maintenance notifications - we typically do not share information on expected non-impacting events, but clearly we need to ensure we calibrate these events and are fully transparent.

· We are reviewing our procedures and systems for quickly resuming cloud operations when an unexpected event like this occurs - unexpected events will happen, our job is to minimize their impacts.

We live by high standards and clearly have not lived up to them. We welcome any feedback. If you would like a call from me, or anyone on our senior team to discuss these issues personally, please reply with a phone number.

We have work to do to earn back your trust. We will not rest until we have.

I did "The Hacker's Manifesto" for a speech contest in high school...it was just funny and a bit painful when that movie came out.
I'd also question the validity of claiming limited risk of data loss when using sharding considering it is still considered alpha although I know for a fact that 10gen is kicking butt to try to make it certified production worthy ASAP.
so, i'm curious, what are the best arguments for this?

the reason i ask is that it seems like the rules, as they currently exist, are valid on paper but illegitimate in practice. is it really worth it to extend the illusion of copyright protection to the rest of the planet knowing full well that it's got little hope of succeeding? or is there a way to argue that the system, as it works in the U.S. is a success?
The involved governments have refused to disclose to their own citizenry the contents of the treaty they're negotiating "for us". That leaves us with only leaks to work with. This is all the accuracy you get, as long as our governments can get away with such gross abuses.
I agree with you. If the entire tech community was up in arms about this (assuming the treaty is really as bad as this article says), I think politicians would notice. They are not all in the pay of the movie business. The more neutral ones might wake up if it appeared the treaty was going to do net damage to the US economy.

I had a conversation similar to this topic with a friend this weekend, but about net neutrality. I contended that certain restrictions put on the internet would be so obtuse that there is no way they could be enforced -- this seems like one of them.

I'm not sure PETA would do that, because they're a legitimate organization that could have action taken against them. But that's an interesting point: if every IP address was reported, how do they enforce or verify it?

Personally, they can pry my internet from my cold dead hands.
Similarly with other common abbreviations, like State codes. Our family conference is at Truckee CA, pronounced - "truckee ka".
Ask HN: why doesn't Google index flash sites?
With the uber smart geeks working there, you would think that they would figure out a way to decompile and index the swf content. Or failing that, Adobe would provide a way to have search engine friendly meta-content for your flash based website.
Last week MI5 in the UK argued against the 3-strikes filesharing laws as they would encourage private citizens to use cryptography better in their filesharing efforts.

If this treaty goes through it very well could be the harbinger of the widespread adoption of darknets, better censorship-resistant networks, and even more creative use of cryptography and networking technologies.

Rather than trying to affect legislative change (which is a viable strategy too), some may wish to consider disruptive technologies which will render treaties such as this irrelevant.
Iraq Swears by Bomb Detector U.S. Sees as Useless
Right but the take down notices would require that you own some IP to allege infringement upon and have the resources to actually produce a non-frivolous legal missive.

I really doubt this is going to be some grand populist legal tool.

It's hard to justify the right for people to break copyright law.

At the same time, I can see how startups that are depending on the safe harbor clause to host copyrighted material to attract users would be upset with the rules of the game changing.
Looks cool, but it is painfully slow (Linux + firefox). Maybe other systems run it better, but for me it is too slow to do much good.

Excellent point. People have become accustomed to an unfettered flow of media and information. They're not just going to throw their hands up and go back to the pre-napster days of walled media gardens.
Yeah, we just launched this today and are in very early stages of beta. We realize speed is an issue right now (we've mostly been testing on Windows and OS X, on which it runs better), and it's definitely something we're working to improve.

should this prove to be true, this is an excellent opportunity for [google | yahoo | microsoft | apple | facebook | any other major tech company that relies on people making things with computers] to petition against this with their ad dollars in a very vocal manner. being the first to rally people against this seems like it'd be far more culturally relevant in the long term than spending the money on a superbowl ad and billboard campaign saying "my brand is good".
How?

You need to put a switchover device somewhere. And that device (or NOC, or power, or router feeding it), can fail.

Unless you want to give you dns addresses a 10 second ttl, and update them as needed.

Really, how? I would love to do this, but I can't think of any method that does not have a single point of failure somewhere. (And I'm not as big as google with my own network lines, something that a regular budget can do.)
From the wikipedia page ( http://en.wikipedia.org/wiki/Protests_against_the_Iraq_War )

"According to the French academic Dominique Reynié, between January 3 and April 12, 2003, 36 million people across the globe took part in almost 3,000 protests against the Iraq war.[3]"

Protests don't seem to have a very good track record.

New accounts on our current platform take some setting up, including administrative message copy (help, stop, etc), usually some custom work to make sure we interface with the external application properly, some training on MMA best practices, and more.

I just had a massive issue developing for Firefox. I spend the better part of yesterday fixing a handful of CSS bugs. It still doesn't work perfectly. I'm not very happy with Gecko at the moment.

I asked a friend on Windows to test it and he showed me it on IE, crippled and appallingly broken. My advice was for him to find another web browser. I'm willing to make Firefox work but draw the line at IE.
I like how the volume slider intelligently resizes. Nice attention to detail.
As I understand it, you'd still have to buy transfer from a tier 1 provider, who'd cut you at the first sign of pressure from the federal government. Logistically, how would one go about doing this?
Destroy them, fund the competition. Boycott any company that encourages the use of DRM. Pirate their products and distribute them via encrypted, untraceable networks like TOR, or plain old sneaker-net. Support individuals and companies who avoid DRM, who treat their users with respect, and who distribute their works directly, etc.
But there's no way Apple and Adobe will bundle it with Flash so it will remain a curiosity for geeks like us.
So I guess 37Signals was wrong after all ;)
Obviously getting rid of copyright would have a devastating effect on innovation and creativity.
You could start another internet. Wouldn't be very useful at the beginning, though.
