  Three Simple Ways to Improve the Security of Your Web App

It seems like web app security has entered the public conscious recently, probably as a result of the press covering the activities of groups like Anonymous and incidents like security breaches at several CAs. Here are a couple of quick security tips to improve the security of your web apps. Think of these as low-hanging fruit, not as a substitute for thorough analysis of your app’s security. If there’s interest in this topic we can do more posts, too - let us know in the com...

  Build your own internet search engine - Part 2

After having started to build my own internet search engine as described in a previous blog post, I now have read some papers and books about web search engine architecture and information retrieval to complete my hobby project. Here is a list of papers and books that I highly recommend to anybody who is interested in this topic: 1. Google: data structures and algorithms by Petteri Huuhka 2. The Anatomy of a Large-Scale Hypertextual Web Search Engine by the Google founde...

  A Solution to CPU-intensive Tasks in IO Loops

Back in October 2011, Ted Dziuba infamously said that Node.js is Cancer.  A provocative title to a provocative article.  The only thing it didn’t really provoke in the commentary was much thought ;)  Zing. My interpretation of the article is that Ted holds up the classic blocking-IO process-per-request (or  thread per request; same difference) model as superior.  Yet we all remember where the blocking-IO forking model got Apache in the early days.  ...

  Popular Golang JSON libraries evaluation

JSON (Javascript Object Notation), a prevailing data exchange format, is widely used in various platforms and languages. Golang, of course, will never miss the support for JSON. And with its own standard library, such as those interfaces like the REST API from the API Service in Kubernetes, it can easily process JSON. Although Go’s library works great, we can still seek those open-source JSON libs in Github to maximize our efficiency. Then the features, performance, applicability of these ...

  Programming Language Readability

Lets compare some Python to Haskell for solving the same problem.  The problem we’ll pick is Trie data-structure for auto-completions.  We are interested not so much in the nitty gritty of the algorithm, but in the language style itself.  Auto-complete has been in the programming news a lot recently; both a Python and a Haskell solver have turned up. (I suspect this post got flagged on Hacker News :(  It never got on the front-page despite the rapid upvoting on a n...

  I hate cut-and-paste

Me, I blame the IDE's.Coding used to be hard. Not because programming itself was overly hard, but mostly because editors absolutely sucked. How much the typical development environment in the 70's and 80's sucked is hard to convey (except for a very lucky few, and those would have likely been using DEC and WANG gear). I got in on the tail end of the punch card era. Punching your own program is lots of fun. Once. And if you drop a deck you get to play with the sorter, which is also lots of fun (o...

  Prototypes and Object Orientation

David Chisnall takes a look at the two dominant paradigms in object-oriented languages (classes and prototypes) and discusses the strengths and weaknesses of each.Two terms are quite often confused when describing programming languages:class-based and object-oriented:Simula was the first class-based language. It provided classes (actually implemented using closures) as a means of encapsulating abstract data types.Smalltalk was the first object-oriented language. It provided a...

  Java Interview Questions

Currently there are many articles online which summarize the list of Java interview questions. Some cover lots of basic questions and some cover some specific questions in specific area such as multithreading. In this post, we will not cover the really basic questions, we will cover something different. For basic question, you can read Java Interview Questions。 Basic What is primitive data type? How many primitive data types in Java? What are they? -- A primitive type is prede...

  Time-saving tips Linux users should know

As a programmer or system administrator, we have more chances of working on *nix platforms. It's tough experience when first start use *nix as we need to face a black screen without knowing what's behind it. Now, if we can have some resources to rely on, then we will find the beautify of *nix. They are fast, efficient and most importantly sexy. Below are some great tips for helping Linux users get used to Linux. This list is a bit long. So be patient. To get more information on a command mention...

  When and Where to Use Pointers in Go

When declaring variables in Go, we usually have two syntax options: In some scenarios, pointers; in others, reference; sometimes, either. It’s great to have choices, but it is also confusing sometimes as to which one in which scenario. To be more reasonable in choice-making, I started from pointers, walked through their natures, and summarized some rules in using them in Go. from unsplash, Jordan Ladikos Pointers Go has pointers. A pointer holds the memory address of a ...
