It’s been a few months already that I haven’t used Windows. The unreal amount of time that it takes to make Ubuntu play sound or use a second monitor and then do it again after a software update drove me straight to Mac.
By the way, why does the “applications” icon look so masonic?
And now for a little exercise in armchair software architecture — the most despicable coder’s pastime. Dear non-coding readers: despite its name, this blog is still mostly not about programming. Just skip this post or something. Dear coders, many of you will probably disagree with me. I am not a very good or accomplished coder myself, and you probably should not be taking your advice from me. But then again, I could be right, so keep your mind open.
You might have been aware of the very popular, but uptime-challenged social networking tool called Twitter. They have one of the best problems to have: too many very active users. The site is so popular that it constantly goes down and displays and “over capacity” screen that the users have nicknamed The Fail Whale.
Rapidly writing and displaying short chunks of text with high concurrency on the web is not one of them unsolvable problems in programming. It’s not easy, but with right people and tools Twitter could be rewritten inside a month. Twitter founders should do some soul searching. Meanwhile the critical mass has already been reached, the niche for bloggers who want to SMS instead of blogging is big, and even horrible uptime can’t this service. I use it myself.
There is a lot of speculation in the blogocube about whether the reason behind the Fail Whale is the wrong choice of technology — the highly hyped and sexy Ruby on Rails and if it can “scale”. Or is it just simple incompetence?
To me Ruby on Rails falls into a class of technologies that are affected by what I call “the VRML syndrome.” Basically, if I wait long enough the hype will go away, the recruiters will stop posting job listings requiring 4 years of experience in a 4 month old technology, books as fat as my two fists will stop being published, and I will not have to learn it.
What’s the problem with Ruby on Rails? Well, it’s the same problem that slightly affects the content management system that I am currently working with (Drupal), and is the reason why I completely gave up using Microsoft web technologies which are saturated with this shit. See, software craptitechts all of a sudden decided that writing CRUD applications is too difficult for regular developers, and complicated GUI tools and frameworks need to be created to help the poor things. CRUD stands for “Create, Read, Update, Delete” and is just a funny way to say “a browser-based application chock-full’o forms”.
The default way to build these is to rather simple. You hand-code the html forms, then you write functions or classes to deal with the form input — validators and SQL queries for creating, updating and deleting. Then you write some code that will query the database and display the saved data in various ways: as pages, xml feeds, etc. None of this is difficult or non-trivial. Bad coders don’t do a good job of validation and input sanitizing resulting in the Little Bobby Tables-type situation, but these things are not very hard to learn and there are great libraries for this.
Ruby on Rails makes it very easy to create CRUD apps without hand-coding forms or writing SQL. RoR goes to great lengths to abstract out SQL, not trusting the developers to do it right. SQL is more functional than procedural, and thus a difficult thing for many programmers to grasp, but it’s not that hard. Really. SQL is located far enough levels from the machine that abstracting it out becomes a horrible thing due to the Law of Leaky Abstractions. Even when you have full control of SQL queries optimizing them is sometimes hard. When they are hidden by another layer it becomes next to impossible.
In short, RoR makes something that is easy (building CRUD apps) trivial, and something that’s hard – optimizing the database layer next to impossible.
In Drupal there are two modules, CCK and Views that allow you to create CRUD entirely through web interfaces. This is a feature that exist in just about every major CMS, it’s just that in Drupal it’s a little buggier and overcomplicated than necessary. These are fine for small websites and are really useful to amateurs. The problem arises when these are used for high traffic websites.
I think that a lot of people will agree with me that writing HTML and SQL queries using GUI tools is amateur hour. You just can’t make a good website with Microsoft Front Page. You can’t, you can’t, you can’t. But in Drupalland it’s all of a sudden fine to use Views to build queries for high traffic sites. Well, it’s not. Dealing with Views and Views Fast Search has been an ongoing nightmare for me. Hell is not even other people’s code in this case. It’s other people’s Views.
RoR, Views, CCK are one level of abstraction higher than you want to be when building a high performance application. The only way the can be an “Enterprise” tool if your enterprise is a) run by a morons that require 100 changes a day AND b) has very few users. In short, if it’s an app for the HR department of a company with 12 employees – knock yourself out. If you are building a public website for millions of people – forget about it.
Your, Deadprogrammer.
P.S. Yes, I know, you can abstract just about everything and reduce your software application to a single button labled “GENERATE MONEY”. You have to be a very smart LISP developer for that.
This is a third, and likely last article in which I pair up food with books. The previous two did not generate a single comment, but I still want to finish the series.
My third favorite cuisine is Japanese. The best Japanese cooking is about the ingredients. Think about it: sashimi is basically sliced up raw fish. It’s an ingredient with the least preparation possible. Yet it’s one of the tastiest things ever, if the fish is good and the chef sliced it well. Simplicity and lightness, that’s what I like about Japanese food. I’ve picked two of my favorite dishes, a fried fish and sea cucumber roe, and paired it up with two simple light reading book series.
My father grew up on Sakhalin island, a place where salmon and even sturgeon roe were dirt cheap and widely available. Kids would thumb their noses at their caviar and smoked fish, my dad said. But there was one fish still highly prized. A humble smelt. Easily caught, it was usually full of delicious roe. Fried – the tastiest thing ever. While fresh, interestingly enough, smelts smell like fresh cucumbers. I first tasted a fried smelt in a Japanese restaurant Yakitori East, one of the few places in New York that serves them. They are also available in Japanese and Korean supermarkets, I’ve bought and fried them at home many times.
Fried smelts are just as addictive as books from the Dortmunder series by Donalde E. Westlake. These are masterpieces of a particular subset of subset of crime fiction genre: a comical caper story. You get too root for a band of bumbling crooks led by John Archibald Dortmunder, a very competent, but extremely unlucky master thief with a beer-inspired last name.
You know how the two Alice stories have a chess game and a card game theme? Well, Dortmunder stories can be thought of as games of American football. The characters are highly specialized, just like football players, they face constant fumbles and setbacks, but from time to time they get to score. In fact, if I remember correctly, one of Dortmunder books even has chapters based on football: “First down”, and so on to more downs than there are in game rules.
Dortmunder’s core crew includes an all-purpose crook Andy Kelp, a thuggery specialist Tiny Bulcher, a getaway driver obsessed with New York City traffic patterns Stan Murch. Kelp and Dortmunder can pick locks, but when the job calls for it experts are called in. So are extra drivers, computer experts, and other colorful characters. Everybody except Stan Murch has long time girlfriends who take part in criminal acts from time to time. Stan’s cab-driving Mom known as “Murch’s mom” is a frequent cast member.
The now-canceled Firefly tv series is definitely inspired by the Dortmunder stories: as a nod, Joss Whedon named one of the big Alliance ships IAV Dortmunder.
There’s something amazingly likable about a competent, but unlucky master thief with a hang-dog look about him. I, for some reason deeply identify with Dortmunder. On the other hand, in real life I’m probably more of Arnie Albright, the friendless and obnoxious (and aware of it) fence. Arnie’s so obnoxious that nobody willingly deals with him (unless they have to). Dortmunder would much prefer dealing with another fence, Stoon who’s unreliable and pays much less.
I’ve read every single Dortmunder book there is. Westlake is currently working on the next installment in which the gang participates in a reality show.

Uni is a simple dish. Well, it’s not much of a dish. It’s sea urchin’s roe. You just dunk it in soy sauce and eat it. Uni had amazing taste: creamy, briny,sweet, custardy. If you watched Iron Chef at all, you probably spent hours listening to the judges rave about uni.
What would go great with uni? Gideon Defoe’s Pirates! books. What are they about? Well, they are about oh, only the most important things in the world. Ham. Piracy. Marine mammals. Science, Philosophy, Love. Sea shanties. Ham.
The nameless Pirate Captain leads a large group of child-like pirates and Cutlass Liz through most amazing adventures. His evil rival Black Bellamy constantly defeats an humiliates him and his crew, but the Pirate Captain does not like to dwell on that.
If I were to trust what I’ve read on the Internet, Pirates! was written to impress a girl to leave her boyfriend (which she didn’t). Defoe also is somehow related to Daniel Defoe.
There are three books out:
