  How key-based cache expiration works

There are only two hard things in Computer Science: cache invalidation and naming things — Phil Karlton Doing cache invalidation by hand is an incredibly frustrating and error-prone process. You’re very likely to forget a spot and let stale data get served. That’s enough to turn most people off russian-doll caching structures, like the one we’re using for Basecamp Next. Thankfully there’s a better way. A much better way. It’s called key-based cac...

  Windows Security Improvements

Traenk is still upset by his recent dive into Windows security.  So much more was promised when the merger of Windows 9x and NT lines was announced, so long ago. I honestly expected better.Long ago, Microsoft announced that it would merge the then NT and Windows 9x lines of products.  Wow!  That means a file access control system, logging, different accounts and filespaces for accounts!  Finally!  We would have a secure version of Windows for our homes!And we do hav...

  passing parameters to XMLHttpRequest’s onreadystatechange function

I’ve been smashing my head against this all day – but I finally got something working consistently and reliable, so I better damn well document it. This is as good a place as any, and hopefully it will be useful to others.I needed to make an Ajax call, so I turned to my good friend XMLHttpRequest. One wrinkle was that I needed to pass in a parameter to it… so I tried:var test = "bar"; req = new XMLHttpRequest(); req.open("GET", myURL, true); req.foo = test; req.onreadystatech...

  Why Python is important for you

I believe that Python is important for software development. While there are more powerful languages (e.g. Lisp), faster languages (e.g. C), more used languages (e.g. Java), and weirder languages (e.g. Haskell), Python gets a lot of different things right, and right in a combination that no other language I know of has done so far. It recognises that you’ll spend a lot more time reading code than writing it, and focuses on guiding developers to write readable code. It’s possible to...

  Five Reasons Why Microsoft's Windows Phone Will Make A Big Splash In The Smartphone Market

The rave reviews for the latest iteration of Microsoft’s Windows Phone aren’t the only reason Microsoft will do better in the smart phone industry than it did in the MP3 player market. Whereas the Zune never really offered anything substantially different from the iPod and never pushed any real boundaries, Microsoft’s latest push into the mobile operating system business is much more bold. Microsoft isn’t rushing it this time – and it shows. So far, tech ...

  Focus of Baidu in the future

In addition to the new generation "Baidu ladies", The biggest highlight of the annual meeting of Baidu is undoubtedly the passionate speech delivered by CEO Yanhong Li with a "Zoro" suite. He emphasized four business focus of Baidu in the future, i.e the traditional search, mobile cloud, LBS and international strategy.

  Find max subarray of an array

In computer science, the maximum subarray problem is the task of finding the contiguous subarray within a one-dimensional array of numbers (containing at least one positive number) which has the largest sum. For example, for the sequence of values −2, 1, −3, 4, −1, 2, 1, −5, 4; the contiguous subarray with the largest sum is 4, −1, 2, 1, with sum 6. The problem was first posed by Ulf Grenander of Brown University in 1977,...

  Why do I need a debugger?

  When I begin to learn a new programming language, I will try and master the debugger for it as early as possible. For example, in 2013, while I touched the Go, there seems only gdb for use. Although gdb itself is not a good choice (From Debugging Go Code with GDB): As a consequence, although GDB can be useful in some situations, it is not a reliable debugger for Go programs, particularly heavily concurrent ones. But at that time there was no other choice. So after delve&nb...

  9 reasons to use Zsh

Like majority *nix users, I have been using bash for many years. Sometimes I feel uncomfortable with bash. I tried use some other shells as well such as ksh, tcsh and zsh which I am going to talk about. A few days ago, I found an open source project ranking in the 6th named oh-my-zsh on Github, I downloaded it and had a try with it. It's amazing. We should use zsh to replace bash now. Why do we need to use zsh? Here is a 4 minutes YouTube video which shows many reasons why we should switch from ...

  Want to be a software engineer? Go to university

This editorial was originally submitted to the Sydney Morning Herald in response to an editorial proclaiming that people wanting to become software engineers should not attend university and instead learn a current popular programming language.   Over the past few years I’ve developed software for large corporations, started the Vodafail campaign, co-founded Mijura and represented Australia in the global Robocup (humanoid robotic soccer) competition. I graduated from University...
