How to determine the version and edition of SQL Server and its components


A Tcpdump Tutorial and Primer

tcpdump is the premier network analysis tool for information security professionals. Having a solid grasp of this über-powerful application is mandatory for anyone desiring a thorough understanding of TCP/IP. Many prefer to use higher level analysis tools such as EtherealWireshark, but I believe this to usually be a mistake.

In a discipline so dependent on a true understanding of concepts vs. rote learning, it’s important to stay fluent in the underlying mechanics of the TCP/IP suite. A thorough grasp of these protocols allows one to troubleshoot at a level far beyond the average analyst, but mastery of the protocols is only possible through continued exposure to them.

When using a tool that displays network traffic a more natural (raw) way the burden of analysis is placed directly on the human rather than the application. This approach cultivates continued and elevated understanding of the TCP/IP suite, and for this reason I strongly advocate using tcpdump instead of other tools whenever possible.

I found out Markdown thanks to a post on Stack Overflow blog about the choice of a way for editing questions and answers.

Markdown was created by John Gruber that defines his creation in this way:

Markdown is a text-to-HTML conversion tool for web writers. Markdown allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML).

Thus, “Markdown” is two things: (1) a plain text formatting syntax; and (2) a software tool, written in Perl, that converts the plain text formatting to HTML. See the Syntax page for details pertaining to Markdown’s formatting syntax. You can try it out, right now, using the online Dingus.

Il parser del linguaggio è stato originariamente realizzato dall’autore in perl. Successivamente ne sono state realizzati altre versioni con differenti linguaggi.

Un interessante porting scritto in Javascript è stato realizzato da AttackLab ed è alla base dell’editor WMD: The Wysiwym Markdown Editor che è possibile provare come simple demo e nella ben più interessante advanced demo. I sorgenti dell’editor sono disponibili su Google Code sotto MIT License.

Tempo fa, cercando una versione per .NET del parser, mi sono imbattuto nel porting fatto da Milan Negovan di ASP.NET Resources. Nel suo articolo Announcing Markdown.NET Milan spiega di aver realizzato il porting a partire dalla versione in PHP realizzata da Michel Fortin e rende disponibili i sorgenti per il download.

Tornato sull’articolo qualche giorno fa, grazie ad un commento di Jeff Atwood scopro che quel codice è stato utilizzato come base per l’implementazione di Markdown presente nel sito Stack Overflow. Jeff ha rilasciato sotto MIT License tale implementazione sotto il nome di MarkdownSharp.
