Invariants are still here. Instead of talking about them in comments, you can have automated test-generation via QuickCheck: http://haskell.org/haskellwiki/Introduction_to_QuickCheck

Why lazily load items yourself instead of use a database, like Postgres or even SQLite, that handles the paging in and out itself?

Build for the internet! Instead of writing a ROM chip, you wrote easy-to-port software. So build code for a web browser, and route around the arbitrary limitations.

A 1GB instance costs $90/mo? A plain 1.7GB instance costs $30/mo. A 50GB instance costs $3500/mo? A plain 68GB instance costs about $1/hr, or $1k/mo. What's the other $2k/mo? These prices look like 3x cost.

In short: don't add an integer to a pointer and expect reliable results. Seriously? In 2010? We're still adding pointers to integers instead of working with actual data structures?

You can go a long way with a SQL database too. I'm writing up an article about getting the two billion words of Wikipedia into an inverted index in a SQLite database entirely in memory, and that's another other order of magnitude bigger.

In summary, Tim Bray is looking to write Android apps in Ruby or another dynamic language. It's interesting that someone who worked on the XML spec says that he's "slipped into the camp of those who find the Java language verbose and rigid

Mr. Surkov says the new city will isolate new businesses from the bureaucracy that handcuffs the Russian economy today. Why not fix that bureaucracy instead, and let all businesses around Russia experience that freedom?

HTML and Javascript are object code at last. As far as I can tell, people use Flash because the development tools are fantastic, not because they're married to the SWF output. This seems like the best of both worlds.

The ISP's logic of people paying for getting bits as well as people paying for receiving bits gets you (in America) text messages that are $0.20 to send, and $0.20 to receive.

This is a better experience if the pages load very fast, and much worse if the pages take a while. If pages take a few seconds to load, then you're checking the browser's spinner instead of the immediate cues which are (designed to be) inc

You don't need a low-level language like C for the query planner and SQL parser. Linspire is doing OS development in Haskell http://lambda-the-ultimate.org/node/1506 and SQLite, with it's 45MLoC of test code for its 67 KLoC of source code

The next parallelized compressor I'd like to see is LZMA. It's basically Lempel-Zip, like gzip, but with a much wider window (tens of megs, vs a few dozen k), and because it's dictionary-based compression it decompresses much faster than b

For my usage, I've found that it's really fast, crashes are isolated, and the developer tools for JS/CSS are fantastic. Good for endusers and hackers both.

Peter Norvig said that he was excited about Google because that's where the biggest data is. TripAdvisor's got a billion points of data about where people travel, and it's growing crazy fast, and it's really exciting to work with.

To make fish oil, you need fish that are low enough in the food chain to not have many PCBs. Fish oil is usually made from the menhaden fish (aka the alewife fish), which used to be plentiful all around the Atlantic coastline of the US, fe
