Some car insurance policies cover rental cars. My insurance covers car rentals, so that I don't need to pay for the insurance coverage when I rent a car.

From the article: "According to a preliminary police report, their car was hit by an oncoming car that seemed to have been traveling south in their northbound lane. The report concluded that Mr. Fortuna would be found at fault."

Last I heard Rhino master was about 10x slower on average, not 50. For most real world applications it doesn't make much of a difference, since you spend most of the time waiting on I/O.

I think this is really far fetched. If you can get a person who has their cell phone number in Google as a recovery option, to not notice that an SMS number comes from two different sources (one of them possible marked as Google), and to enter a security number (explicitly labelled so) on an insecure webpage, I think it would be easier to just ask for their Gmail password.

I agree. I can't say I like standard practise of employers owning everything their employees do whether in or out of work, or requiring that you stop anything they don't own.

However, this is hardly something that is limited to Goldmans or financial services. I'm pretty sure that Apple require you not to work on side projects, for example.

We had a discussion regarding this at my company - Future Workshops - last week, and decided that what people work on in their own time is their own business, with the caveats that a) people don't work in conflict with any clients, b) the IP is clearly separate, and c) it doesn't affect their day job in a negative way.

Poll: If you where a billionaire, would you marry a fat girl?
When I saw the pictures of Zuckerbergs Girlfriend whom he just married, I was thinking: Interesting. She looks cute but not outright gorgeous. In fact she is a little fat. I asked myself: If I was a famous billionaire - would I marry a fat girl? And my answer is : no. There are just too many uber-wonderful girls out there whom I could have a great time with. So I would not settle. I feel like Im in to hack life in general, not just the tech and business part.

Am I an exception? Or is Zuckerberg an exception?

Seems like I cannot post a poll, so I post this as a normal thread.
> China has this huge hinterland that wasn't there in South Korea

Exactly. China can't solely depend on export for its growth, like South Korea did. That will make its development quite a bit slower, not to mention more difficult. Parts of the country will become developed first (this has already significantly happened in Beijing and Shanghai), and then bring the rest of the country up. In the process, there will be significant economic disparities, which has the potential to rupture the social fabric.
> In some cases you really have too much diversity of data structures and then it a NoSQL solution can be helpful. An example can come to mind: a notification engine with tens of diverse notification format, each with their variable data and their localized display templates.

Actually the relational database solution to that problem -- an arbitrary mix of various data types -- is to use a table with a variety of columns of different data types. For instance: Str1, Str2, Str3, Str4, Int1, Int2, Int3, etc. -- for as many as you need to store what you want to store. Obviously they should all be nullable and you would need a PK (and FK) to whatever it is you are storing it with. Next, you build views on top of this for each different type of data stored in this mix table, and in this view you then name each column sensibly. Using triggers on the view (or without: Oracle can figure out most inserts if the SELECT query is trivial) you can insert data into the mix table as well.
With all the financial products the banking world creates, I'm sure someone will come up with an insurance policy for this. Sure it won't be cheap, but will be a solution.
That actually is how car insurance works. There's a property insurance component ("collision" and "comprehensive") that insures you against loss or damage to your property. Then there's a more expensive liability insurance component that insures you against liability as a driver of any car. The property insurance portion is optional as long as you own your car outright.
It depends. If capital accumulation is an important limiting factor in your country's growth, as it is in most of Africa, then adding more people will tend to increase the overall GDP but decrease the per capita GDP. If you're at the productivity frontier, however, and you're more limited by your ability to figure out how to use more capital (innovation). In this case there is still a small marginal return on having more capital per worker, but every worker is also a source of more innovation so its really hard to say whether adding more people (up to a certain point) will increase or decrease the per capita GDP.

Generally speaking, when a country develops to a certain point it gets what's called a demographic dividend[1]. The population has been growing rapidly in the past, so there aren't that many old people to take care of. With wealth people start having less babies, though, so there are also a relatively small number of children to take care of relative to the number of working adults. Countries in this position can, if they manage to avoid messing up, grow very rapidly.

There was a program on BBC2 recently [2] of a business owner with textile factories in both China & the UK. One of the illustrations they made was an increase in pay in China (something like 3-fold in recent years IIRC). The employees over there were getting quite vocal, they'd go to the office and demand a 50% increase or walk away. There were also markets were employers would advertise their business, job seekers compared pay and extras. One of the things that stood out most were the worker's clothes & haircut: colorful, modern, trendy.

Perhaps the answer here is to insist that a renter must either have valid insurance already that would pay out to third parties in the event that they were driving any vehicle. Most fully comprehensive insurance in the UK already covers this assuming you have valid fully comp on some car already.

For example I (being fully insured on my own car) could drive a friend's car without being specifically insured on it and were I to get involved in an accident (that was my fault) then damage to third parties are covered but damages to my friend's car are not unless his insurance specifically covers me.

If the renter doesn't have this insurance already simply increase the amount they have to pay to rent in order to cover it.
Ugh, so depressing... go to college, rack up enormous amounts of debt, and hope to find a job so that you can start paying off the monthly minimums for the seemingly the rest of your life.
And... HN seems to have jumped the shark.

As much as I like Mongo and comparisons to other DBs I doubt that your comparison does really help anyone:

=> I found it hard to get your message by just skimming through the blog post: the first results lack measuring units, is it request per second or total request? The graphs were even more confusing—they do not give the reader quickly the relevant information and the conclusion isn't clear.

=> I missed information if you set up respective indexes for querying Mongo (correct me if I am wrong). And I don't know if you used the new hstore feature on Postgres.

=> This is still a micro benchmark with limited expressiveness. The overall use case, data model and queries are directd rather towards the NoSQL and general full text search capabilities. Take a use case with lots of joins/links, random reads and writes and we will have a totally different picture (thus, your title is misleading).

So if one wants to make a comparison between Mongo and Postgres I would like to see how Postgres' hstore and the new JSON datatype feel in terms of daily usage and performance compared to Mongo (because these two new features compete directly with NoSQL DBs and the latter one with Mongo in particular).

Is there a custom keyboard like with iSSH: http://www.zinger-soft.com/support_g_3.html

The problem is that certain punctuation symbols (: . { }) are used often and they require a modal change to input them. I point to iSSH because the ability to reconfigure the keyboard makes it easy to type large blocks of code.

I wouldn't say it's confusing, but the inconsistent baselines are very misleading. I'm also pretty surprised that some of the tests are anywhere near comparable, since they had different indexes.

"That's why we can't have nice things"

Too much liability issues and because of (most likely) an irresponsible driver now they're (or better, someone that can pin any cost on the injured) goes after the car renter, car manufacturer, road authority, etc. They'll probably make a way for Steve Jobs to be liable as well if they can, I guess

"no longer theoretical" No crap sherlock. People have been getting injured in car accidents for the past 100 years.

By getting into a car and driving you assume a non zero risk of being injured or killed in a car accident. Do you want zero risk? Live in a bubble

Now his suddenly becomes a multi-million dollar cash cow for several 3rd parties.

Except for the victims of course, who'll have to deal with giant health costs (because of similar excess liability and regulation meandering by the authorities and greed by the medical industry)

Sure, liability is important, if it involved a drunk driver for example, or a fault that comes from the car maker.

But there's always a risk! And preventing some risks causes even more risks sometimes.

About the Django part... yeah, I've heard that said, but the fact is that Rails was first and most of the cool parts of Django are things that they ended up doing like Rails.

Having used both, my opinion is that even today Django didn't understand some of the core ways that Rails was superior so didn't copy the right things. So yeah, Django was around and can sort of claim some concurrency with Rails development and I'm sure it even influenced Rails in small ways.

In terms of leading in a new paradigm, though, Rails did it. Django didn't.

Django is the Ringo of the greatness of the Beatles. Sure, Ringo was there swinging his sticks and even wrote a couple of catchy tunes. Sure, he contributed in his own small ways... but seriously he wasn't the leader and he wasn't the secret ingredient to the band's phenomenal success.

In the enterprise, it's always an emergency. If it isn't, it gets ignored, because the pipeline for getting 'non emergencies' done is constantly pre-empted for emergencies.

That said, every good process has the ability to handle exceptions. If it was truly the emergency it sounds like, he should have been able to make the change to get it up and running ASAP and then made the change properly through the normal process.

But the question of whether an "emergency" truly is, is a complicated one.
Might be. According to my initial question - does that make me an exception or is it normal?

Are Files Ready to Change?
Some of David Gelernter's oft quoted file ideas:

"Modern computing is based on an analogy between computers and file cabinets that is fundamentally wrong and affects nearly every move we make. (We store "files" on disks, write "records," organize files into "folders" — file-cabinet language.) Computers are fundamentally unlike file cabinets because they can take action."

"Our standard policy on file names has far-reaching consequences: doesn't merely force us to make up names where no name is called for; also imposes strong limits on our handling of an important class of documents — ones that arrive from the outside world. A newly-arrived email message (for example) can't stand on its own as a separate document — can't show up alongside other files in searches, sit by itself on the desktop, be opened or printed independently; it has no name, so it must be buried on arrival inside some existing file (the mail file) that does have a name. The same holds for incoming photos and faxes, Web bookmarks, scanned images..."

"You shouldn't have to put files in directories. The directories should reach out and take them. If a file belongs in six directories, all six should reach out and grab it automatically, simultaneously."

"A file should be allowed to have no name, one name or many names. Many files should be allowed to share one name. A file should be allowed to be in no directory, one directory, or many directories. Many files should be allowed to share one directory. Of these eight possibilities, only three are legal and the other five are banned — for no good reason."

It begs the question if files and the core systems on which they are read/stored are ready to change? And will it be a start-up that makes the leap, or a lonely computer scientist who has no stake in the market?

I don't know CL, but in python function definitions can be executed multiple times... at the top level this happens at module import, so it ends up being only once. But in nested definitions, e.g.

def foo():
def bar():
...
return bar
foo() == foo() # false

Two different function objects are created. If, in the above examle, bar took a pram thelist=[], each call to foo would produce a bar function with a different list instance for thelist. The default values can be read as expressions passed to the function object constructor, rather than a bit of code to be evaluated each function run.

I don't know how CL works in this regard, nor do I know which is better or worse. I think the explanation linked did a terrible job conflating first class functions with execution and runtime models. Some of the answers below it explain better tho. :)

Hi -- I'm one of the authors of Tahoe-LAFS. I haven't read your RACS paper before, but it looks pretty good. I appreciate the emphasis on real-world economics and on the costs of vendor lock-in. I haven't yet completely digested your results numbers to see how they inform my business, but I definitely will.

It's too bad that you weren't aware of, or didn't cite, Tahoe-LAFS when you wrote that paper! Even though you used my zfec library, which I created (by copying Luigi Rizzo's feclib) for Tahoe-LAFS's use. Heh heh heh.

I tried to get Tahoe-LAFS's existence registered in the official academic research world by publishing this: http://scholar.google.com/scholar?cites=7212771373747133487&... but it didn't really work. Most of the subsequent research that probably should have cited Tahoe-LAFS still didn't.

Perhaps that 5-page paper was too telegraphic to communicate a lot of the important properties. For example, it does not spell out the fact that Tahoe-LAFS includes a kind of proof-of-storage/proof-of-retrievability protocol. Also, perhaps, I chose too obscure of a venue to publish it in. I'm not sure.

For your reading pleasure here is a big rant by me on my blog, whining that Tahoe-LAFS is deserving of more attention than HAIL (which you do cite):

https://lafsgateway.zooko.com/uri/URI:DIR2-RO:d73ap7mtjvv7y6...

"It is frustrating to me that the authors of HAIL are apparently unaware of Tahoe-LAFS, which elegantly solves most of the problems that they set out to solve, which is open source, and which was deployed to the public, storing millions of files, and summarized in a peer-reviewed workshop paper before the HAIL paper was published."

Interesting, whenever I'm at a coffee shop I find there is mostly no need for headphones because there is already enough random noise about.

Well, that's a lie. I use headphones when somebody is talking at the next table whose voice projects. I don't know what it is, but when some people talk to one another it sounds like birds chattering, but some people you can hear clearly over surprisingly great distances.

That then becomes a problem - being able to make out specific words.
Also worth studying is adaptive Huffman coding. See:

http://en.wikipedia.org/wiki/Adaptive_Huffman_coding

Using adaptive coding, you either begin with no tree or you begin with a tree in a known state and change the tree with each character processed. This allows for one-pass encoding of a set of data.

The first law of DB comparisons says: in order to compare two database systems a deep understanding of both systems is required, however the more expert an user is the less likely is to compare two systems (he will just pick what seems more suitable for the task) thus almost all the comparisons attempts are garbage.

One of the things most web apps have in common is that they do not accept payments by anything other than debit/credit card. I've been considering developing a service that would allow payment by bank transfer in response to an invoice. Basic functionality is:

* Invoice sent to customer on a frequency selected by user
* Payment made directly to user with remittance advice sent to email address generated by my service. If email can't be used, I propose using a service that scans hard copy mail.
* Scan emails and attachments for unique invoice number and when found post back to user's application that invoice has been paid

It's a fairly non-trivial application so thought I would solicit some feedback on the idea.
