Alas, BMW buyers often cannot opt out of keyless entry, because for some models BMW includes it in popular bundled packages, such that it's impossible for the consumer to avoid buying it without losing other worthwhile features.

This consumer-unfriendly bundling results in BMW buyers often facing what can only be described as ridiculous choices ("which one do I want: a rear-view camera that reduces the risk of accident, OR non-keyless entry that reduces the risk of theft?").

Seems like it'd paint you into a bit of a corner if you ever needed to change anything about your password hashing.

Say some mythical unbreakable hash algorithm comes along that's O(1) and you decide you want to move to it, you're forever going to have to drag along these terabytes of junk hashes as you're entire userbase wont log in (giving you the opertunity to change how their password is stored) and since you can't tell the noise from the signal you'll forever have that enormous table of hashes from that time you tried to be extra clever.

"How are you doing?" is the least of my worries. For the past several years when a friend or family member asks "How is your job?", I answer honestly, sometimes slightly sugar coated if I'm feeling positive that day, and always feel like I've just had an unpleasant bowel movement. But, what I've come to realize is that I am the problem. I chose this path. When I've had problems at a job, it is a result of not leaving it and making the choice to take it in the first place. Now, many of the details you don't learn until after you take it, but I would have had the same general idea what it would have been like had I taken the time to really think about it. I look forward to a time when I can find something that I'm great at, that I love doing, and I love how and where I do it. But, despite all the books I read and positive things said on HN and elsewhere- I haven't found it yet, and really I would love to give up feeling shitty because I can't find it. So, while I'm still honest that things aren't perfect, it mights me realize each time I say what is going on that I have more work to do to set things right, and I just don't know exactly how to do that. For entrepreneurs and freelancers, most of the problems are inevitable, but there is a lot of help out there for you if you look. For those of us with regular jobs, no one will hold our hands to find answers.
I found this really helpful. Not so much to do with the actual article, but to do with actual making me aware of Google Refine.

Installation was a breeze. I couldn't find any instructions, but it was as simple as downloading for Linux, extracting, the running the shell script.

http://code.google.com/p/google-refine/downloads/detail?name...

The application automatically opens in a new Chrome window.

From here, I grabbed a data dump from one of our external providers.

We work with a lot of providers who are really technologically challenged. I'd love to be able to say, here you are.. here is our API, start pushing your content to us. But in practice they don't even know what their XML feeds do. We need their data, but getting a consistent dataset from them when they seem to change their format regularly is a pain! And when importing only 10 or so items at a time it's excruciatingly painful.

Today I learnt how easy that can be with Google Refine!

I just don't see indoor navigation as a huge problem to be solved. And this seems a phenomenally complicated solution to a small problem.

GPS works because outside is an enormous, unfamiliar place with tens of billions of destinations. Inside is small, relatively familiar, and even a large building has, at most, hundreds of destinations.

Just watching the demo, it's super cool and super intelligent. But it doesn't look like it can do direction - it can only tell direction after you've walked a certain distance. How will it cope with large magnetic things that move - eg Forklift trucks, vehicles, trolleys, wire cages etc.

I don't buy it. Ikea is the only potential place I could see this being of use, and there's no way anyone's going to bake in an extra sensor to a smartphone on the offchance. Look how slow adoption NFC has seen and that's a MASSIVE problem with multiple applications and a clear financial incentive.

I used to work at the Dell technical support call center. And they used to tell us that customer service is a part of the product. At first it seemed they were taking overboard with regards to customer service.

But our managers made it clear, customer satisfaction came first. Everything else came next. We would even support calls which didn't even have warranty. Sometimes even teach people how to use computers, like practical tutions. Especially to the elderly. We would even make follow up calls to ensure everything was right.

Soon the results showed. I mean Apple fanboys might laugh at us. But we sold more stuff by good customer service and courtesy than apple would have sold by innovation.

Thats why I said mitigated: you are not going to make the problem go away, but you can lessen the impact. I have a similar workflow as you have in Ruby, but it takes great care to make sure that this kind of workflow is possible. Usually, I use a regexp and sign off every change by hand. Considering that I read my own code a lot, I also get to see my own stuff again.

Thanks for catching this one.
It uses the compass smartphones already have, not a new sensor.
Sure, they only way to truly solve these things is stop making it a mechanical process and turn it into an interactive process with people involved who have common sense. Patents should be "deny by default" with the party arguing why they should get one. If they can convince the e.g. "board of experts" then they get it. Then we just have to execute the first "board of experts" member who takes a bribe. :)

Interesting paper on the subject: Dunn et al. - If money doesn't make you happy, then you probably aren't spending it right http://www.wjh.harvard.edu/~dtg/DUNN%20GILBERT%20&%20WIL...
That's not the point; I don't expect to be able to walk up to your front door with a random Yale key, jam it in and out a few times and have your lock reconfigured to accept my key instead of yours. That's what's happening here - it's not as sophisticated as a lock pick attack, nor as brute force as smashing the dashboard and shorting the appropriate wires.

It's a blind spot in the system that shouldn't exist if the car was locked. The OBD port simply shouldn't be physically connected if the doors are locked. A relay on the CAN bus pins trigged from the central locking might be a start.

I wonder if that direct adjustment is actually the proper way to do it. That's implying a hypothesis that the money-happiness relationship varies due to COL, but is constant once adjusted for purchasing-power parity. But it seems at least plausible that the relationship is a different one. I'd be interested if anyone's directly studied what the money-happiness correlation is in NYC versus, say, Omaha. I wouldn't be surprised to see a deviation in either direction; perhaps New Yorkers need more than the COL-adjusted equivalent to be happy, or perhaps they need less. May even vary among sub-groups.

In my own case, I've found that the amount of money I need to be satisfied with my income tends to scale less than linearly with COL. In higher-COL places I spend a bigger proportion of my income on rent, and do more low-cost entertainment, in part because more low-cost entertainment is available. For example, I've lived in both Houston and Santa Cruz, and I was quite happy doing a lot of free and cheap things in Santa Cruz, with its great beaches, hiking, etc. In Houston, I had to spend money for entertainment.

I agree that laziness turned out to be a bad default for the reasons you mentioned (other Haskellers may disagree with me on that point), but I don't think that means that it was a mistake to pursue it. It forced the designers to build in purity which turned out to be immensely valuable. Having laziness as a default is also not the kind of decision you can easily revert.

You're right to say that the field of static analysis has been very active. What you're forgetting is that this has been in no small part due to type theory.

I think the reason you don't find people talking about actual code, as you put it, is because actual code and so called mathematical gibberish are one and the same thing.

Lisp is based on the idea that code are data are equivalent, Haskell is based on the idea that code and mathematical gibberish are equivalent.

I didn't intend to imply that you didn't know the benefits of functional programming. I could have worded that better. Do you know the benefits of typed functional programming?

Having recently delved into lisp, I do miss the static analysis that goes on before the program starts. I realized that I used types to plan out the program before I started coding and I miss having the type-checker picking holes in my plans. I'm determined to stick at it though so that I can see what I'm missing in terms of meta-programming and other dynamic features.
Good point!

The fact that the communication protocol used is openly known, much like all internet communications, means that an attack is easy to craft.

Somehow that is a solved problem with internet and all other open security architecture. Why isn't it solved on these cars?

This sounds like either NIH combined with piss poor security engineering done in the name of looking fancy, result of financial constraints or both.

I'm sure some engineers objected that "this is fundamentally insecure!" but got turned down from someone doing the budgets.

We build indoor navigation systems for hospitals in Canada and it is indeed a huge problem. The larger institutions are like a maze with wings and additions added over the course of decades. Making a route to your appointment though 3 buildings, up 2 elevators, and over a wing is easy. Helping you actually stay on the route as you follow it is not. If this new tech is cheaper to deploy than dozens, if not hundreds, of wifi beacons then it could be a real win.

As for your assertion about "Apple fanboys", have you seen how much Apple innovation sells? The last article I saw said Apple makes more revenue from the IPhone than MS makes... full stop.

Amusingly enough most of them aren't - OBD access to interesting features (as opposed to a very limited standard set) usually costs a LOT of money. $10K one-off charge plus an update subscription for example.

OBD-II has essentially failed by allowing so-called "extended" PIDs - which all manufacturers define in their own specific ways. See the Torque forum for endless threads of people wanting extended PIDs for specific models to use with the Torque OBD app.

I suspect this is one reason why good OBD scan tools cost a lot more than the parts cost of an ELM chipset and a few sockets - a trivial adapter costs £20, but a Bavarian Tech scan tool for BMW costs £200, presumably to recoup the costs of buying access to the extended PIDs.

Which we have, not only is there a coarse scale global magnetic field model (two versions, in fact) there are detailed high resolution maps for large areas of the world (eg: all of Mali, all of Australia, most of Canada, much of the central 'stans) where mineral exploration has taken place.

The positioning is complicated by the drift over time (there's a "new" global model every five years and for specific times & locations interpolation is performed) and fluctuates daily (as the Earth turns there's a diurnal pulsing in the induced magnetic field).

This is where "a bit of signal processing" comes into play.

The good news is the maths, the field testing, and the application of it is all a good 50 years old.

I always thought a reasonable solution to this problem was triangulating via wifi and bluetooth signal strength from access points of known location. I tried it as a weekend project a few years ago but random fading was a killer and I never got it to work that well. Seems like it should be possible though. Are there good reasons not to do it this way?
The book looks awesome, thanks a lot for the link!

Just yesterday, I started teaching my co-founder how to code in python, and wanted to very quickly get to something useful to give him inspiration to keep going.

I ended up starting with the python interpreter for ~30 min, followed by writing a very short program to show a random inspirational quote on the command line, and then turned it into a module so we could import it back in the interpreter. The end goal was to show how programs get built up from smaller pieces and can become more and more complex.

I think he really started to get it once we added a few test functions to test the different range of inputs to his "get_quote" function.

Next time, I'm going to show him Django via simple demo site and hopefully he'll be at the point where he can start editing HTML. (I'll either use https://github.com/mpdaugherty/django-demo-project, which displays quotes and demonstrates views and templates, or https://github.com/mpdaugherty/RateBeers, which rates beers and adds in some DB models, depending on how far he gets).
Refocusing our efforts and investments
I suppose you don't live in a dense city with a lot of indoors and underground infrastructure. In some places you easily spend half a mile indoors between underground train platforms or to the exit on the surface, or in walkways inside and in between buildings where there's no reliable signal. Other times it's simply because part of the commute goes through tunnels or the entire trip is underground. This really breaks a lot of useful tools, for example location based alerts or simply using navigation to get to the correct exit of a station (office, mall, etc.) which if you get it wrong can mean an extra mile of walking.
Whoa :) This is very clever. I've been working on indoor positioning quite a long time already and might give this a try.
