  Meta tag in HTML header

In server response, we can use response.setHeader() to set the meta information in header of a HTML page. The usage is response.setHeader(name,context); meta is used to simulate the response header of HTTP protocol in HTML page. It should be put between the <head> and </head> tag. 1. <meta name="Generator" content="" > <!--This is to specify the tool which generates this page such as Microsoft FrontPage 4.0 etc --> 2. <meta name="keywords" content=""> <!-- To tel...

  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 ...

  Why is single threaded Redis so fast

Redis is a high-performance, in-memory key-value database. According to official test reports, it can support around 100,000 QPS (queries per second) on a single machine. However, Redis uses a single-threaded architecture in its design. Why does Redis still have such high performance with a single-threaded design? Wouldn't it be better to use multiple threads for concurrent request processing? In this article, let's explore why Redis has a single-threaded architecture and still maintains its spe...

  Google Dart? Don’t bet against JavaScript

Procotols, programming languages and operating systems all compete in a constantly evolving software ecosystem. Out of that ecosystem only a few technologies truly have staying power and survive over the long term. An example? How about Ethernet? It’s been a survivor over the last thirty years despite existing in a constantly changing landscape that’s been populated with many worthy competitors. Ethernetâ€â„...

  The Number One Trait of a Great Developer

Maybe the best programmers aren’t those who spectacularly solve crazy problems, but those who don’t create them, which is much more silent. – Lena HerrmannWhen I look around at other companies hiring Ruby on Rails developers, I see them focusing on three major traits: Super-smart; Large community following; Deep Ruby knowledge. They’re all wrong. While these are great aspects in moderation, they all miss the number one quality of a fantastic developer: Judge...

  The business of software

Inspired by a talk I gave yesterday at the BOS conference. This is long, feel free to skip!My first real job was leading a team that created five massive computer games for the Commodore 64. The games were so big they needed four floppy disks each, and the project was so complex (and the hardware systems so sketchy) that on more than one occasion, smoke started coming out of the drives.Success was a product that didn't crash, start a fire or lead to a nervous breakdown.Writing software...

  SQL Injection through HTTP Headers

During vulnerability assessment or penetration testing, identifying the input vectors of the target application is a primordial step. Sometimes, when dealing with Web application testing, verification routines related to SQL injection flaws discovery are restricted to the GET and POST variables as the unique inputs vectors ever. What about other HTTP header parameters? Aren’t they potential input vectors for SQL injection attacks? How can one test all these HTTP parameters and whic...
