agreed. email i just sent to Scheiner:

Bruce,

I like what you came up with - but it has a really large problem in that, if you are stopped and compelled to show your computer, you would become a combatant by refusing to share information. You would immediately be seen as a risk, get arrested, and then compelled to give up the name of an accomplice. However, as you know, most of this is just theater- since you have nothing to hide, the only real problem is the "in plain sight" provisions that could get you in trouble for having a couple of downloaded movies on your desktop.

So how about this?

Get a larger than required laptop disk, and partition it, with one size being a tradtional, smaller size. 250 or 120GB perhaps.

On the larger partition, stick your fave OS, work etc.

On the smaller, put a plain win xp install, with some fake data and so on. Outlook with generated emails that look reasonably fresh and so forth.

Then, have a boot loader that can be configured to autoboot to either system unless a special key combination is entered on system start.

This way, once you're done with your flight, you can encrypt your partition and reboot into your "clean" system. Then, if you get stopped, you can happily show the system. At that point, there really would not be any evidence for any further search, so you would not easily be detained. You could also go further by ensuring your clean system didn't see the other partition, and that you had a sticker showing the hard drive size being the same as the smaller partition.

Ghost Drives.

simpler and safer than having to risk your machine.

I think the best places to start are places frequented by your target audience. That may be a place as big as Facebook or as small as a antique automotive forum.

If you don't know what audience you're targeting, that is probably a bad business strategy...but if you want to do a little research, put some ads on a 'broad-spectrum' website like Google, Facebook, Twitter, etc. and then run some stats on your web server logs after a while. They'll be able to tell you where your traffic is coming from, what people are searching for to find your site, and so forth, which you can then use to better target your ads, etc.
I'm getting about 250k sha1 hamming distance calculations per core per second, on an Intel(R) Xeon(R) CPU 3050 @ 2.13GHz (from /proc/cpuinfo). This is a full implementation... I can just drop in the word list and challenge phrase on game day.

Intel(R) Xeon(R) CPU 5148 @ 2.33GHz gives me 300k/sec.

Anyone else have a quick & dirty benchmark?

I'm the author of the blog post and to answer your question, yes, I know about Incanter. In fact, I found out about Parallel Colt via Incanter. I've played around with it a little and it looks very cool.

I was initially going to build my algorithm using its libraries as a base but I thought a simpler first step would be to write it without pulling in too many extra dependencies.

I learnt Haskell before I tried using Clojure and really like it as a language. It doesn't surprise me that it runs faster. I'm guessing the feature value look-ups don't involve the extra unboxing that Java's maps do.

It's generally a poor assumption that averaging a huge number of inaccurate devices is going to end up with the same sound as one high quality set. I would support finding out what the "average" home equipment sounds like, but suggest "perfection" is the best approximation is laughable. For example, the average single cone speaker is going to be setup to handle mid range sounds ok, but it's going to miss highs and lows.

I think the real advantage is people get used to how their system adjusts music. So by following the convention it's going to sound "normal" to them.
Schneier has previously written about TrueCrypt, which has a cryptographically protected version of this defense (it creates a deniable hidden partition within the free space of another encrypted partition): http://www.schneier.com/blog/archives/2008/07/truecrypts_den...

Obviously there are many other ways to simply hide your data from customs (e.g. put it on a microSD card and physically hide it). But the solution in this article has the interesting property that "it also allows you to deny a customs official your data without having to lie or pretend" which might be nice if, say, you want to publish it in the IT manual for your public corporation.
$50 per ounce seems high enough to drive lots of potential consumers to the black market.

EDIT: And either way, you're trying to levy taxes on things people can already grow and distribute themselves. So it turns out that out of tax enforcement they'd have to shut down illegal grow operations anyway, just so some corporation can sell green cigarettes to the mass market. This isn't the legalization we're looking for.
Well, the "cleanliness" is probably because it hasn't been open-source for too long - most of the original work was done by a dedicated team of software engineers most likely operating under fairly strict code guidelines.

Regardless of anyone's personal stance on the subject, I think it's fair to say that it would require a miracle for pot to actually get legalized in the next 3 years.

Politicians may personally agree that legalization is a good idea, but there are very few who are willing to risk being called out for being weak on anything, the "war on drugs" included.

That's correct. it's 6/8 bits per color.

Note that an image that uses 6-bit color with an alpha channel will have 24 bits per pixel, which shouldn't be confused with the 32 bites per pixel of 8-bit color.
On the other hand, I think a lot of estimates on what marijuana taxes would take in are overestimated.

In any case, enforcement savings would long before taxes. Possibly alone. Outright legalisation is rarely really on the table. It's decriminalisation of personal use, reducing it to rarely enforced minor infringement or something along those lines.

You can't expect the full suite of benefits from that. You save quite a lot on enforcement and incarceration. Mostly, the proponents want that to go into treatment.

But you still have associated crime, Criminals still control the industry. You don't get any taxes.
Unfortunately our current veto-happy governor would sooner see benefits for children, the needy, and the poor cut to absolute zero before allowing past any policy that isn't staunchly conservative. If we're $26 billion in debt and he's striking down tax increases, this has absolutely no chance of ever becoming law.
Especially since:

- Such a lively market already exists.

- People can grow their own.

I run 2 web sites that use Wordpress (latest versions) with mediatemple.net and I keep getting hacked with an iframe insert. It installs malware on visitors computers.

Can anyone tell me what steps they take to ensure that wordpress is 100 percent secure from attacks (or at least 99.9 percent)?

I have tried changing the file attributes to 444 but that has not worked.

Any feedback will be helpful.

Thanks.
I don't get the "revelation" he's claiming that this is. When you're finding work or distance, two examples he gave, you're still finding the area under a curve. Sure, the axes will be representing time and velocity when calculating distance, or force and distance while calculating work, but that is the exact same thing as calculating area when the axes are used to represent distances of width and height.

He's right that's it's akin to multiplication. In fact, you can find the areas under trapezoids using very simple integrations, but he did nothing to discount the fact that definite integrals are all about areas under the curve.
From http://en.wikipedia.org/wiki/Marijuana :

The United Nations Office on Drugs and Crime claims in its 2008 World Drug Report that typical US retail prices are 10-15 dollars per gram (approximately $430 per ounce).[76]

So $50/oz doesn't seem very high (ha) when the legalization would bring the price down more than $50.
That's the combination on my luggage!
It's because he's frequently right, and has little patience for people that can't hack it. He expects a higher level of coding maturity and complexity than most people do. Zed's attitude results in a less welcoming image but a higher level of technical expertise. Whether that is a good thing or not in the long run is an open question in my mind.

I usually can't stand people like that, but there are two reasons why I like him. First, if someone finds a bug in his code or shows (with proof) that he did something wrong, he takes it just as well as he gives it. And second, he actually writes some pretty damn good code.

I think we need more people like him. There are too many ex PHP turned Rails developers who assume just because they can deploy a decent web app that they know everything. Hell, some of Zed's most vocal disagreements have been about performance. Zed actually knows his stuff and can back up his point of view with statistics. Most Rails developers on the other hand have no idea about some of the computer science concepts needed to talk about performance in an informed way.

Zed's got a lot of public opinion against him. Just watch some of his keynotes to get a better idea of what he is actually like.
uh, $50 dollars an ounce is not an unreasonable price - at all.
You don't have to hate Zed to love this. :)
It's my favorite article :)

It "supports" millions of colors; it just displays some of them with multiple pixel tricks. Which is probably fine with me -- I haven't seen a comparison where I could tell the difference without blowing the pixels up.

There is no point in altering the laptop hard drives sticker. If they have gone through the trouble of opening the hatch to see that they are likely going to just remove the drive and hook it up to their equipment at which point it's going to be obvious there's more than meets the eye.
The "$50 per ounce" is a hypothetical tax on legal marijuana, not the hypothetical price of legal marijuana.
They levy taxes on things people can already make at home now (beer for one). It works. Most people are lazy enough to let the market do it for them. Look at all the medical marijuana stores--those people could grow their own but they decide to buy instead.

Worst case scenario and everyone grows their own we still aren't spending billions of dollars hunting down, prosecuting and imprisoning people for weed.
What's a reasonable price?
There may be a support issue for Apple here. Imagine a customer purchases a Pre and syncs it to iTunes, but Palm's reverse-engineering of the iPod-iTunes protocol is incomplete and iTunes crashes as a result (and does so reproducibly). Many customers would follow this up with Apple, but Apple would likely be unable to help them (presuming they were even interested in doing so).
hang on there; how come a higher tax rate would kill the startup market? A more complex business tax regime, sure, but you are only taxed on your profits and what you pay yourself. You don't pay much in taxes until your company actually starts making money.

Especially considering that capital gains is treated differently (and taxed less) than income, it seems to me like the most advantageous course to take in a time of high taxation is to start a business, and re-invest as much of your profit as possible. Then, at some point sell it and pay capital gains on your winnings. (or perhaps sit on it until tax rates go down a bit.)

Now, obviously a high tax rate will cause people to spend less, but that's going to hurt all businesses, not just startups. From where I stand, as a small company, it seems that I am much better positioned to compete on price than larger companies in my market.
El reg threw this one about a few months ago too. Apparently, legalising would save the UK a packet.

I agree, Mongrel was a real boon when the alternatives paled in comparison.

A $50 per ounce fee is nothing, especially considering that the price would plummet as the market would be flooded with suppliers. The likely scenario is that an ounce after legalization, with the fee, would still be cheaper than a pre-legalization ounce.

And about being able to grow your own: if legalization happens, there's no way they'd rescind that right. Distributing what you grow is another issue altogether, an issue that I, and many others I assume, don't really care about.
I wonder if this also involved switching the Ruby binary to the Ruby Enterprise Edition? Or did you move to Passenger and keep the same Ruby binary?
Let's be clear here: Apple doesn't prevent syncing with the iTunes library. What they prevent is third parties using iTunes to do so. It is less a case of shutting out a competitor as it is squashing a parasite. Nokia and RIM both provide software to sync with a user's iTunes library, why won't Palm?
When I look back on the years [most of the 70's] I spent programming 16K x 18-bit single-digit megaherz machines, with single-digit megabyte hard disks (although they were head-per-track, which makes them much faster - similar to lousy SSD's), and what I was able to get done on them, I laugh....

The crime is only there due the high markups on the product, given its difficulty to obtain. You could produce the product much cheaper legally.

In the case of the most addictive substances that tend to drive a lot of petty crime it's probably better to give the stuff away free.
Ironically mongrel & dependencies only require a handful of lines of patching to work on 1.9 - the fact that no one has bothered for many months now shows just how unpopular mongrel has become.
It seems a little suspicious that these articles and books about barefoot running were published at the same time Nike and a few other shoe companies come out with shoes meant to emulate barefoot running. The first thing I thought of when I read this article was "The Suit is Back!"

In any case, track and field athletes have always, and still do, wear paper-thin shoes with spikes.
the parts that often fail are hard drives and fans, so eliminate those. maybe an embedded pc (think router) with huge ssd+ram is stable at ambient room temperature. and almost never breaks (AC power adaptor normally will break first).

if google can subsidize internet with her routers (with huge ssd+ram), she basically outsources the power and maintenance to local people around the globe.

if such router can direct queries into its huge ssd+ram cache (think squid + LRU?), then search can be faster
Probably the most sweeping impact of legalizing marijuana would be that doing so would greatly dis-empower foreign drug lords and criminal organizations.

Very quickly Billions of dollars would be redirected into the legitimate economy, and there would be far less need for American soldiers all over central and south America.

it's 6.25 bucks an eighth. I'd happily pay that as a tax, and I think a lot of other people would too.
According to wiki answers 1 ounce of marijuana ranges from 110$ to 500$. In mass production you could probably grow marijuana at something like 1$ a pound, so like cigarettes you would mostly be paying the cost of tax. My guess is it would be a little cheaper than it is now say 65$ an ounce which would limit it's value on the black market.

For comparison 1 ounce is around 2 packs cigarettes which is and ~8$, but I think marijuana has a lower active dose.

It's amazing how pretty much every person in that thread refused to believe Apple would break it. This is not an accident, Apple did it deliberately - they warned about it, and then they did it.

Edit: And I get downmodded for this one too, which I expected. People clearly really like Apple and refuse to believe they would do this.
Seems to be helpful for physicists, not so much for mathematicians. A physicist will look at an integral and say "oh, yeah, charge is field times area, that makes sense!", while a mathematician isn't going to say the same about measures. I think that's the "revelation" he was going for.

BTW, I always thought of convolution as multiplication. Anyone else feel cheated by this guy for that reason?

Mongrel was effectively so much better than using FastCGI and it served well for a time. Now passenger is a step in the right direction, easier to setup and monitor.

We had some memory consumption problems also when we decided to migrate and just switching to passenger did little for those. It was really the switch to REE that made the difference. Also the memory was not really from complex database operation, it was for rendering huge erb templates for the Googlebots. In the end there were no reason to always generate those templates and caching solved the problem definitively, but with REE it was already acceptable and we could have let it be for some months too.
If it's so obvious and important to his professional work why doesn't he drag his ass into the Apple store where he bought his MacBook and check out the screens of all available models? This would have been advised before buying the 13" machine, but hey at least he can get a refund. Apple already "misled" him, so why does he care what they say? Walk into the store and check for yourself. Or can he not tell the difference?
That's absolutely false. He's veto happy because raising taxes during a recession is the dumbest possible thing a government attemping to restart the economy could do. The government has to cut spending along with the rest of us.

In response to your issue, I see no reason why he would be opposed to legalizing weed, especially when it provides extra tax money which could be used to close the budget deficit. He's a lame duck - it's not like he's afraid of getting flak from righteous social conservatives who are opposed at this point in time.

I still like Google better though.

Very interesting. Some DCs measure the cost of running at a higher temperature. Examining the cost of purchasing replacement hardware and the strain downtime places on relationships. Having a global presence you can do Smart DC Distribution base on the traffic they receive from the region they can spin down servers at night or during hotter days. I wonder if they reuse the heat(energy) produced.
Hi, thanks for the comment. My main point is that going beyond the "area" understanding leads to a better understanding of calculus:

* Finding area does not readily imply an inverse operation, but multiplication does ("division" is differentiation, and it is the inverse). Most students would not posit the existence of an inverse of "finding the area", but multiplication is easy to reason about.

* Multiplication scales to N variables (multiple integration), while the mental model of "area" breaks down after the 3rd dimension.

* Multiplication matches more closely to what is meant in a lot of cases. When you integrate speed and time, you are trying to multiply them. You probably don't mean to imply that you're going to plot them on a graph and take the area under the curve as distance. That may be the mechanics of it, but finding area is not the purpose of the operation.

So, area isn't wrong by any means, it's just a limiting viewpoint in my mind, and there are better analogies out there. Thanks for the comment!
