How Browsers Work: Behind the Scenes of Modern Web Browsers Web browsers are the most widely used software. In this primer, I will explain how they work behind the scenes. We will see what happens when you type google.com in the address bar until you see the Google page on the browser screen. The browsers we will talk about There are five major browsers used on desktop today: Chrome, Internet Explorer, Firefox, Safari and Opera. The browser's main functionality The main function of a browser is to present the web resource you choose, by requesting it from the server and displaying it in the browser window.

Back to top The bash shell The bash shell is one of several shells available for Linux. Before we delve deeper into bash, recall that a shell is a program that accepts and executes commands. Shells have some builtin commands, such as cd, break, and exec. Shells also use three standard I/O streams: Input streams provide input to programs, usually from terminal keystrokes. Listing 1.

When i first made my way over here to check out headphones, I found that it was exceptionally confusing to see people referencing letters and numbers without brand names or referencing letters and number referencing both headphones and amps in the same post, so if I could get some cooperation to create this list, I think a lot of newer members might appreciate it. Here's my initial list off the top of my head: Audio Technica AD700 Audio Technica A700 Audio Technica AD900 Audio Technica A900 Beyerdynamic DT 770 Beyerdynamic DT 880 Beyerdynamic DT 990 Beyerdynamic T5 Beyerdynamic T1 Denon AH D2000 Denon AH D5000 Denon AH D7000 Fischer FA-011 Grado SR60 Grado SR80 Grado SR125 Grado SR225 Grado SR325 Grado RS1 Grado RS2 Grado PS1 Hifiman HE-5 Hifiman HE-6

SQL Injection Attacks by Example A customer asked that we check out his intranet site, which was used by the company's employees and customers. This was part of a larger security review, and though we'd not actually used SQL injection to penetrate a network before, we were pretty familiar with the general concepts. We were completely successful in this engagement, and wanted to recount the steps taken as an illustration. "SQL Injection" is subset of the an unverified/unsanitized user input vulnerability ("buffer overflows" are a different subset), and the idea is to convince the application to run SQL code that was not intended. We'll note that this was a somewhat winding road with more than one wrong turn, and others with more experience will certainly have different -- and better -- approaches. There have been other papers on SQL injection, including some that are much more detailed, but this one shows the rationale of discovery as much as the process of exploitation. So we'll do it in steps. A standalone query of
