  Java Doesn't Need to Be So Bad

I do a lot of Java coding and I enjoy it. I admit that there is a lot of typing, often a lot of boilerplate and getting even simple tasks done can involve too much work. Most of the tools that try to fix these problems trade one moment saved for another lost. Maven's XML based configuration file is a good example: Thank you for making my project easier to manage and I won't forget that you made me edit XML to do so. These are the things that you live with, these are the things you trade for ...

  The most stupid C bug ever

I have been programming for a number of years already. I have seen others introduce bugs, and I have also introduced (and solved!) many bugs while coding. Off-by-one, buffer-overflow, treating pointers as pointees, different behaviors or the same function (this is specially true for cross-platform applications), race conditions, deadlocks, threading issues. I think I have seen quite a few of the typical issues. Yet recently I lost a lot of time to what I would call the most stupid C bug in ...

  Paradigms of Iteration in JavaScript

One of the joys of programming is that no matter how simple a problem may seem there are always tons of ways to solve it. It can be good practice to go back and revisit fundamentals by solving simple problems with as many implementations as you can think of. In this post we'll explore approaches to basic iteration in JavaScript. This style of exercise is a good interviewing technique, too, because it's open ended and leads to good discussions. The focus isn't a tricky, wacky problem you're...

  Kubernetes: Docker out

Recently，The hottest news in the Kubernetes circle that docker will be deprecated has been confirmed by the release of 1.20. Docker support in the Kubelet is now deprecated and will be removed in a future release. The Kubelet uses a module called “dockershim” which implements CRI support for Docker and it has seen maintenance issues in the Kubernetes community. We encourage you to evaluate moving to a container runtime that is a full-fledged implementation of CRI (v1alpha1 or v...

  Install LAMP in two easy steps

You might have seen my earlier post related to installing PHP, Apache and MySQL on UBUNTU 11.10. That process contains number of steps and some lengthy commands which we can not remember easily. After good comments from Gaurav and Coward I have managed to get that lengthy process in just 2 steps. So I thought its great to share with all readers to they can get benefit as...

  Breakdown Kubernetes Container Runtime

Keeping on learning Kubernetes piece by piece and having a deeper understanding of its advantages, I am no longer shocked at its rapid development and popularity. Though backed by big companies like Google is undoubtedly the push, its design, features, and convenience are the biggest attraction. Most of all, it disintegrates the monolithic Internet system governance and lifecycle and offers a new management method. Kubernetes is a set of concepts, including various resource types like Pod, Deplo...

  var in JavaScript

Geoff published an article sometime ago--"How one missing var ruined our launch". This article described one case where MelonCard uses Node.js as their backend system, suddenly there was a small registration peak period--50-100 people registered concurrently, then the entire website stopped responding and many other strange problems showed up. When they were investigating the source of the problem, they found one missing var in the following code.app.all(‘/apps/:user_id/status’, fun...

Now many websites such as Facebook, Twitter support one browsing style which is when you click one link on their sites, the page will not be redirected, instead only the page contents are updated and URL on address bar is changed.
