  I've run out of adjectives

The news of Dennis Ritchie's passing hit hard. So much has been written in the past day. His impact was enormous, and outside the tech world, mostly unknown - but very much felt. C underpins everything. My whole career has grown out of C and Unix. Wow.For most engineers working today, it's hard to understand the euphoria I felt in the 70s when a programming language finally came along that I (and everyone else) could use to move up from writing in assembler to a real programming l...

  Fujitsu CTO: Flash is just a stopgap

Flash is a necessary waystation as we travel to a single in-memory storage architecture. That's the view from a Fujitsu chief technology officer's office. Dr Joseph Reger, CTO at Fujitsu Technology Solutions, is that office-holder, and – according to him – flash is beset with problems that will become unsolvable. He says we are seeing increases in flash density at the expense of our ability to read and write data. Each shrink in process geometry, from 3X to 2X and onto 1X, ...

  Set file permission in Java

Prior to Java 6,  there is no good solution at the Java level to provide file permission management. You need to implement your own native methods or call the Runtime.exec() to invoke the system routine such as chmod in LInux. Since Java 6, Java introduces a set of methods which can be used to set the file permission at Java level. These methods include: File.setReadable(boolean); File.setWritable(boolean); FIle.setExecutable(boolean); File.setReadable(boolean, boolean); File.setWritable(bo...

  Hackers vs. Coders

Photo Credit: Pranav MistryBeing a good hacker is an invaluable skill. But is being a coder the same as being a hacker? Is it possible that coders are at a creative disadvantage to hackers who don’t know how to code?Here’s a story that helped me see the difference.I was recently invited to mentor at Startup Weekend. On Friday night, we gathered to eat pizza, pitch ideas, create teams and discuss launch plans. At the end of the day, everyone was feeling great about what theyââ...

  A Sip of Go Log

Logging is indispensable in any code that we need its support both in debugging and in statistics. However, a package that filled withfmt.Println/fmt.Printf printing various messages can never be considered a read-to-be-adopted package, which can be optimized by a simple change, using Golang’s native log package to print information to standard output or to a file. Then, how to apply the log package? Are there any limitations? If so, can we seek open-source packages? Let&rsq...

  What's Wrong with the For Loop

Closures in Java are a hot topic of late. A few really smart people are drafting a proposal to add closures to a future version of the language. However, the proposed syntax and the linguistic addition are getting a lot of push back from many Java programmers. Today, Elliotte Rusty Harold posted his doubts about the merits of closures in Java. Specifically, he asks "Why Hate the for Loop?": I don’t know what it is some people have against for loops that they’re so eager to...

  Which one has a worse reputation, JavaScript or PHP?

There has a been a lot of criticism of PHP over being a badly designed programming language. JavaScript seems quite a similar language with loose-typing and flexible array declarations/memory management, but is widely adopted by industry leaders such as Google. Google even has a JavaScript style guide. Many people think that PHP has a worse reputation than JavaScript. Carlos Ribeiro gave his analysis on a high level which doesn't touch the language syntax. Attributing JavaScript success to it be...

  Javascript Frameworks Are Too Small

A while back I stumbled upon a great post by Jean-Baptiste Queru. It describes the incredible depth of the modern technology stack. Layers upon layers of complex science, hardware, and software, each layer creating a simpler abstraction around the previous. This ultimately enables our paltry human brains to create amazing things that would otherwise be impossible (or really difficult). This is, in my opinion, the lifeblood of modern software development. For some reason, however, when i...
