Monitoring a Log File

By Derek Bullet_white Posted in Plugins Bullet_white Comments Comments

A log file is a lot like a neglected board game covered in dust. I don’t play board games that often, but when I do, I always say “we should do this more often”. The log files we have for Scout collect lots of great information, but we only reference them when investigating an incident. They often aren’t a part of our daily lives (but they should be).

Yaroslav Lazor of Railsware, an agile Ruby on Rails development firm, has created a Scout plugin that makes it easy to extract basic information from a log file on a regular basis. His Log Watcher plugin, brilliant in its simplicity, counts the number of occurrences of a given pattern in a file, reporting the data to Scout.

Why web developers have more to learn from Wall Street than Steve Jobs

By Derek Bullet_white Posted in Business Bullet_white Comments Comments

In 2006, the biggest risk-taker on Wall Street looked like John Paulson. This certainly wasn’t based on Paulson’s past behavior. Paulson managed a middle-of-the pack hedge fund. He made careful, boring deals. He rode the bus and liked to ride his bicycle. In other words, he was the anti-Gordon Gekko.

The risk Paulson was taking? He was betting against the mortgage market using credit default swaps. Insuring $1 million in high-risk mortgages was dirt cheap – around $10,000. If all of the homeowners made their payments, Paulson would be out $10,000. If all of the homeowners defaulted, he would make the entire value of the bundle – $1 million.

For Paulson to make money, these high-risk borrowers needed to default. At the time, most analysts thought that a perfect storm of rising unemployment rates, higher interest rates, and poor local economic health was needed to trigger widespread defaults. However, Paulson’s extensive modeling showed widespread defaults required just one trigger: flatlining home prices. With home appreciation rising at 5 times the rate seen from 1975-2000, there was plenty of room to fall back.

MongoDB Slow Queries Monitoring

By Andre Bullet_white Posted in Plugins Bullet_white Comments Comments

Thanks to Jacob Harris, we have a MongoDB Slow Queries plugin for Scout.

The MongoDB plugin captures the number of slow queries per minute according to the threshold you specify. It also reports details of any slow queries that take place.

Of course, like any other Scout plugin, you can set trend triggers, graph results, etc.

Please install from our directory, kick the tires, and let us know if you have any feedback!

Also, for general MongoDB Monitoring, checkout the MongoDB Monitoring Plugin.

When tech startups == closed restaurants

By Derek Bullet_white Posted in Business Bullet_white Comments Comments

Bootstrapped tech startups are a lot like restaurants started by quality chefs. It’s easy to find restaurants serving award-winning food that fail. There are lots of self-funded startups started by smart developers that either never launch or die a painful death. Writing quality software – just like serving good food – is the foundation, but it’s not going to make you profitable.

Like chefs who take pride in their food and constantly strive to improve it, developers like us are never done making our software better. There is an unlimited list of things we’d like to improve. Better scheduling and planning won’t shrink the todo list – it’s a leaking todo list that spawns another todo when one is completed.
