Quoth PG: "After all these years of moderating Hacker News, I understand it very well, and it is going to hate this project unless the entire design spec is “don’t offend HN.”"

That's prescient feedback. I want you to succeed, I really do. I understand the vision for the product. But tell me: which part, specifically, of "We automatically developed a CarFax report on Patrick McKenzie for distribution to recruiters" is supposed to convey value to me?

I thought I had forgotten CarFax's value proposition, so I Googled them: "Don't run the risk of buying a used car with costly hidden problems." Nope, looks like I remembered accurately. That sounds catastrophically against my interests.

How about this? "We automatically discover what you're great at by comparing you to other people who are great at it, and optionally introduce companies looking for great people to you. It's like having a resume which updates automatically and comprehensively matches all the buzzword bingo without you having to do any work you're not already doing."
I like this. I like this a lot. This is perfect for someone who just needs to get a few thoughts together and can't be bothered with firing up Dia or something similarly bloated.

> 1.Mkt isn't like BM. BM permits -ve values & any market index say SPY must be non-negative.

That's one reason everybody models log-returns, which map non-negative prices onto the whole real line.

> 2. We (quants) model market indices like SPY as a log-normal process like so : dS = rSdt + sigmaSdz ... But that doesn't make S itself Brownian.

That's a geometric Brownian motion with drift. It is in fact the model developed by Louis Bachelier in his thesis of 1900 that presented the first mathematical description of Brownian motion.

Much of the argument you're trying to make can be made better, in my opinion, simply by pointing people to the Grossman-Stiglitz paradox [1]: markets cannot be fully informationally efficient or no one would have the incentive to provide information to them through trading.

You rails guys think you're the only game in town. A spaghetti coder is gonna have issues regardless of the language/framework.

Also the barrier to any framework in any language is the same.
From the article:

"Ed note: Dalrymple has a different account. He said that his laugh was in relation to another comment—about hockey—and he didn’t walk out first. His comments regarding Android at WWDC had nothing to do with Blue being female."

Not saying one is right and the other is wrong, just pointing out that there were two different accounts of the exchange.

Also, if someone said that to me I wouldn't want to attend the event either, regardless of my gender. This is not excluding women from tech, this is excluding nice people. Either way it needs to change, but it seems unnecessary to bring gender into this (assuming, of course, that he would have made the same comment to someone of a different gender).

Silverlight Application Development
I wouldn't bother setting up all the fancy stuff. Get a second machine, install HyperV on both and set up live migration.

Install your web app on a Windows 2008 VM on serverA ; move the VM to ServerB, reboot serverA, then move the VM back. For applying patches to the VM image itself, I figure it should reboot in what, about 60 seconds or less?

You can get fancier, have separate dev, staging, production VMs etc., adding web balancer and what not later. Then when you want, you can go all-VM should you ever tire of the hardware maintenance.

Airbus reveals aircraft of the future
There are tons of engineers at Google (assuming the hint). Some of which must be entrepreneurial. Why not reach out to those you know first rather than approach strangers? It's one thing for people to not know coders personally or all their friends are already doing something so they have no choice. It's another to be surrounded by engineers and not be able to work with that. Sends a strong signal even if there isn't one.

Not to be a dick about this either but most people think they have a knack for "envisioning innovative products and how they can deliver value" but most fail on finding challenges within their own ideas. Of course on the positive side, you're at least willing to hash things out and explore ideas. That said though, you probably need to bring some solid value proposition of which I'm not seeing in the above pitch.
Validation is not a central part of most biz applications. Validation on the client side is a UX convenience, but not strictly necessary because anyone with two brian cells to rub together is going to ignore any client side validation and run the real input validation on the server.
> Node.js appeals to people who already know Javascript and don’t want to learn a new language

This is a blanket statement that perhaps displays the author's opinion on Javascript as a language itself.
The objective isn't necessarily to be the coder or to prove you're better or good enough to take the place of a full time coder. It's to at least be able to build your prototype and have a better understanding on the tech side. Doing so will prove more value prop in the short run and help find a true coder to team with.
I've heard of a few deployments where the dev environment is MRI/"C-ruby" and production is JRuby.
Just this comment here alone would deter me from wanting to work with you or something like this. Getting a prototype up isn't the same as finding someone long term to build a company together. It helps to see if there is traction and better to understand what you're doing. No one ever said that you can't find a cofounder AFTER you get the prototype done. This is not an either or type of argument.
IA64 is by far the most aggressive VLIW implementation we have. It was significantly ahead of its time, in that it relied on "sufficiently advanced compilers" that still haven't materialized. We'll get there eventually, and future architectures will push complexity into the compiler the way Itanium did when the compiler is able to bear the load. We're already there for easy-to-schedule, well-understood codes (e.g., ATI GPUs are VLIW), but I'm betting more Itanium-like microarchitecture will come out of the woodwork eventually.

In a sense, VLIW/EPIC was one of the only things IA64 was trying to do differently than existing architectures. The chips have a bunch of cool RAS features, but Power5-7 have most of those too.

Well, consider the case when nothing has changed. All they do is hard link the top level directory and they are done.

2011-06-12 -> 2011-06-13

On my Linux machine when I do rsync backups it has to create a new inode for each file in the new directory whether or not it has changed. Even on a moderately sized directory tree this can take an hour or more (you can benchmark yourself with "cp -al". Try copying your whole disk just for fun). Time machine completes a cycle in 10 minutes or so and that includes the new data copying.

For small amounts of files I agree with you that the hard linked directories would make a trivial difference. Keep in mind that by default Time Machine backs up /usr, /Applications and /System along with your user data which is quite a lot of files in the end.

That's all just creating the new backup's directory tree. The new data copying itself is fast because Time Machine uses the FSEvents API (which is like inotify but more suitable for backing up) so that it knows exactly what it has to back up beforehand (no scanning). If your computer crashes or you switch disks or otherwise screw up your FSEvents DB then it does have to scan the whole disk looking for changes and that can take hours.

So technically it is fast because it uses FSEvents and also because it can hard link directories. If either of those things are missing then the process would be significantly slower.
Hi, Everybody.

My name is Michael and I produce WriterViews.

I'm new to Hacker News, and am sharing this interview because I'm proud of it. Ramit was really open about how he built his blog/brand - and I learned a lot.

I think the HN community would be particularly interested in watching from around [2:45], where Ramit talks about how he develops processes to get bigger results with less work.

I'd appreciate any feedback.

Example of a Thesis
Developing a thesis for their research project can be a tough task. The thesis cannot be formulated immediately. There is much planning and gathering of knowledge which precedes it. An example of a thesis can be become a useful tool in order to educate students on how to formulate their thesis.
I think the big difference between now and when Rails was first starting to gain popularity is that now most of the blogs are primarily covering advanced/obscure topics related to rails. Years ago, most blog posts were about the basics of getting started with rails. Now those old posts no longer apply to the newer version of rails. This is not the fault of rails and it is not the fault of bloggers. There is no shortage of books available to learn rails, but learning a new framework via books is not always the most approachable way for newcomers to learn rails. It would be awesome if someone rebooted some of the older railscasts by Ryan Bates Railscasts for rails 3.1, but that takes a lot of effort and in another year or two the content will again become stale. I would love to see some people blog about the basics of using new versions of rails.

Rails has been improving over the years, and I think excellent design decisions have been made. I do not think it is the fault of rails that the author feels that rails is less approachable.
Where do you get your numbers for that? I'm genuinely curious. I had the opposite impression; but I don't have any numbers at all to back it up.
I noticed it when they miscounted, and it was kind of interesting how it happened.

The professor talked through a revolution, and then resumed counting from his previous number. The student who was counting in the background just sort of reset to the professor's count instead of correcting him, and it seemed entirely subconscious.

Not mindblowing, but I found that little moment more intriguing than the laminar flow.

> Using the same language at both the client and server end has some serious benefits

Like what? I hear this argument all the time, but it's always unsubstantiated.

In my experience, the choice of language is less important than the programmer's understanding of facts that have little to do with the language itself.

If you are developing client-side browser code, for instance, then you have little choice but to use Javascript.

But learning JavaScript is not the hard part: mainstream programming languages, in and of themselves, are rarely difficult to master.

On the contrary, the skill that separates the superior engineers from the inferior ones is the mastery of the environment that the program operates in.

For front-end developers, it is an intricate understanding of how browsers work (i.e., the DOM and supported events) and some good understanding of how to optimize requests back to the server. (There is probably much more they know than this, but I'm not a front-end developer.)

Similarly, back-end developers have much to learn about how to efficiently and reliably serve (hopefully) many thousands of requests per second. They need to understand the limitations of their servers, how to manage memory and storage effectively, and build reliable, operable services.

For both types, these skills often take many years to master, and they are hardly interchangeable. Consider that developers themselves often describe themselves as "front-end" and "back-end" people. The fact that you can now use JavaScript on the server side does little to disturb this reality; and things wouldn't change much if you could run Perl or Python or Ruby in the browser tomorrow.

There is a "Manually manage music" checkbox for iPods, which lets you drag and drop stuff mostly like any other device. If you hate syncing so much, why haven't you just checked that?

Syncing works for me, and probably does for most other people out there as well. In most cases, it's pretty good at putting the latest and greatest on my device without me having to do much except plug it in. If that doesn't work for you, okay, but if the manual option is there, why aren't you using it?

Where to start, um, well, your app is worth whatever you price it at. You could double or quadruple your price potentially, but you never know until you tweak and test on price. So, start by playing with price in a couple weeks.

Also, there is a finite market size for certain apps. So, at some point your app is going to likely have a steady stream of sales. It might take off, but I don't know. Most don't.

Last, don't do much or any advertising if you are selling a $1 product. Unless you are confident that the market size is huge and just waiting for your app, it's not worth it. Figuring that a cheap cost per user acquisition might be $5-10, you would lose about $4 per customer or more.

Admittedly your app is a small utility, but if it has value, make people pay a reasonable amount. I'm guessing it could go as high as $5 and people wouldn't flinch, but I have no data to back up that assertion.

Higher price means you have more wiggle room to do interesting advertising. You can always start by reaching out to every blogger who uses a mac. Maybe do some cheapo youtube vids.

Also, don't limit yourself to just one app. Experiment with lots of ideas til something sticks.

Optimizing for pearls, not sand
I feel this Flask extension is too small to worth using over py-bcrypt at all; the example in this extension's README is no more different than:

import bcrypt
pw_hash = bcrypt.hashpw('secret', bcrypt.gensalt())
pw_hash == bcrypt.hashpw('secret', pw_hash)

I also don't understand why `generate_password_hash` returns a tuple, not just string; the salt is always in the password hash so there's no need to return the salt. My suggestions:

1. Make the extension (optionally) read `log_rounds` from `app.config`.

2. Support for anything other than py-bcrypt, e.g. cryptacular or bcryptor.

There are some interesting ideas in this post. I teach binary numeral notation, and then arithmetic with that notation, to third graders each year as part of the math classes I teach in my town. One of my favorite resources is the book Algebra by Gelfand and Shen,

http://www.amazon.com/Algebra-Israel-M-Gelfand/dp/0817636773

which includes problems in representing numbers in binary notation and doing arithmetic with binary notation that are very approachable to young learners. (The problems are also very good review for undergraduate math majors

http://www.ocf.berkeley.edu/~abhishek/chicmath.htm

and help adults think more deeply about mathematics, which is why I like teaching with this book as a source of lesson topics.)

Edit after seeing other comment: I also mention to the children in my classes the Babylonian numerals,

http://www-groups.dcs.st-and.ac.uk/~history/HistTopics/Babyl...

in which the implicit base is base sixty. The link shown here mentions speculation from ancient Greece that that base was chosen because it has many different prime factors. That Babylonian system of numerals, whatever its origin, appears to be related to historical relics such as counting sixty minutes in an hour or 360 degrees of arc in a circle.
