  Introduction to the Application of eBPF in Golang

Most of the time, when we develop software or even use software, we play within the safe boundaries of the operating system. We might not know how the network interface welcomes that IP packet, nor how the filesystem handles the inodes when we save a file. This boundary is called user space, which is where we write applications, libraries, and tools. But there's another world, kernel space, where the operating system's kernel resides and is responsible for managing system resources such as memor...

There are many CSS preprocessors that front-end develop...

Update 2: Sorry for the downtime. Leave it to the distributed systems guy to make his blog unavailable. Nginx saves the day.It’s always frustrating reading rants about Scala because they never articulate the actual complexities in the core language.Understandable—this post is intended fill that gap, and it wasn’t exactly easy to put together. But there’s been so much resistance to the very thought that the complexity exists at all, even from on up high, that I thou...

  Ways to make elements in HTML center aligned horizontally

In our daily HTML design,  it is an easy job to horizontally center align an element with known width. <div class="element">I am<a href="http://www.aiubug.com" target="_blank" rel="external" title=""> bug </a>！</div>  .element{width:960px;margin:0 auto;}  The above codes set the width of the div block and horizontally center align it.

  Lasagna Code

Anyone who claims to be even remotely versed in computer science knows what “spaghetti code” is. That type of code still sadly exists. But today we also have, for lack of a better term — and sticking to the pasta metaphor — “lasagna code”.Lasagna Code is layer upon layer of abstractions, objects and other meaningless misdirections that result in bloated, hard to maintain code all in the name of “clarity”. It drives me nuts to see how badly some c...

  Can we believe our eyes?

Several days ago, one of our customers submitted a sample (SHA1: fbe71968d4c5399c2906b56d9feadf19a35beb97, detected as TrojanDropper:Win32/Vundo.L). This trojan hijacks  the hosts “vk.com” and “vkontakte.ru” (both social networking sites in Russia)and redirects them to 92.38.209.252, but achieves this in an unusual way. A common  method used to hijack a website and redirect it to a site of the attacker’s choice is to add an entry in the Windows hosts f...
