FUCK PASSWORDS
I'm so tired of passwords. So, so, so tired. Most people don't understand this. Most people use the same password everywhere. Most people can just mechanically type out password3 in every password box, smirking to themselves at how clever they are, because who would ever guess 3 instead of 1? I don't do that. Let me tell you what i do. I generate a different password for every service, based on a convoluted master password and the name of the thing. I do this because it's what you're...

Cross Browser HTML5 Drag and Drop
HTML5 Drag and Drop has been talked about a lot lately, but it’s hard to find really useful information about implementing it across multiple browsers.Mozilla, Apple and Microsoft all have pages describing how to use it, but their examples seem to work only in their particular browser (Apple’s example doesn’t even work in their own! Updated, Jan. 11, 2009: Although I have not been able to get this example working on Safari 2.0.4 and 3....

The trap of the performance sweet spot
This post is about JavaScript performance but I would like to start it by telling a story that might seem unrelated to JS. Please bear with me if you don’t like C.A story of a C programmer writing JavaScriptMr. C. is a C programmer as you can probably guess from his name. Today he was asked by his boss to write a very simple function: given an array of numbered 2d points calculate vector sum of all even numbered points... He opens his favorite text editor and quickly types somet...

Why Emacs?
PreludeIf you are a professional writer – i.e., if someone else is getting paid to worry about how your words are formatted and printed – Emacs outshines all other editing software in approximately the same way that the noonday sun does the stars. It is not just bigger and brighter; it simply makes everything else vanish.Neal StephensonIn the Beginning … Was the Command LineI’m an Emacs user and I’m proud of the fact. I know my reasons for using it (and loving i...
A journey to investigate a goroutine leakage case
In Go, creating goroutines is straightforward, but improper usage may result in a large number of goroutines unable to terminate, leading to resource leakage and memory leaks over time. The key to avoiding goroutine leaks is to manage the lifecycle of goroutines properly. By exporting runtime metrics and utilizing pprof, one can detect and resolve goroutine leakage issues. This post will go through one real case encountered by the author. The author maintains a service that connects to a targe...

Coding tricks of game developers
If you've got any real world programming experience then no doubt at some point you've had to resort to some quick and dirty fix to get a problem solved or a feature implemented while a deadline loomed large. Game developers often experience a horrific "crunch" (also known as a "death march"), which happens in the last few months of a project leading up to the game's release date. Failing to meet the deadline can often mean the project gets cancelled or even worse, you lose your job. So w...

Secure Your Go Code With Vulnerability Check Tool
Security vulnerabilities exist in any language and any code, some are written by ourselves, but more are from the upstream dependencies, even the underlying Linux. We have discussed the security protection methods for Go and Kubernetes Image in Path to a Perfect Go Dockerfile and Image Vulnerability Scanning for Optimal Kubernetes Security, in which the security scanning was performed based on generic. As the Go community grows, more and more open-source packages have caused ...

Learning Server-Side JavaScript with Node.js
Node.js is all the buzz at the moment, and makes creating high performance, real-time web applications easy. It allows JavaScript to be used end to end, both on the server and on the client. This tutorial will walk you through the installation of Node and your first “Hello World†program, to building a scalable streaming Twitter server.What is Node.js?JavaScript has traditionally only run in the web browser, but recently there has been considerable interest in bringing it to the...

Java Sequential IO Performance
Many applications record a series of events to file-based storage for later use. This can be anything from logging and auditing, through to keeping a transaction redo log in an event sourced design or its close relative CQRS. Java has a number of means by which a file can be sequentially written to, or read back again. This article explores some of these mechanisms to understand their performance characteristics. For the scope of this article I will be using pre-a...

proftpd FTP Server setup on Ubuntu
A- The GUI way (for beginners only)For those who are new to linux and don't want to use a FTP server without GUI, or just for those who don't use often their FTP server and wish to set it quickly without a high level of security, there is a GTK GUI for proftpd.Be careful, it's less secure than configuring yourself your server.1- Install proftpd and gproftpd with synaptic or with this command :Code:sudo apt-get install proftpd gproftpd2-Play with the GUI and set up quickly your server.Beware...
