If your website gets hacked, it can affect both your income and your reputation. Keeping your web space malware-free requires daily effort. In this article, learn how to locate infected files, check server logs, clean your files, and take measures to minimize the chances of being hacked again.
In general, Linux and Windows development environments aren't compatible. Windows developers often use native integrated development environments (IDE) such as Visual Studio, while Linux programmers use command-line tools such as Make and the GNU Compiler Collection (GCC). While there are cross platform IDEs, most notably Eclipse, the two worlds of Linux and Windows often remain separate.
Users always want faster access to web resources. If your website is sluggish and serves pages slowly, would-be visitors won't wait, and will go elsewhere instead. Fortunately, you can employ several tools to compress your code and output and thus send fewer bytes over the Net, enhancing download times and creating a better user experience.
By facilitating secure access to remote systems, SSH makes systems administrators' jobs easier. SSH provides data communication, remote command-line login, and remote command execution, all over a secure channel. Database administrators can take advantage of SSH to manage a MySQL installation remotely.
You can improve PostgreSQL text search performance by executing searches directly in the database interface layer. Advanced text search mechanisms include SELECT LIKE queries, queries with regular expressions, the Levenshtein algorithm, Trigram, TSvector and TSquery, and Metaphone.
Summarizing vim-abolish (a.k.a. abolish.vim) is so difficult that even Tim Pope, its creator, begins his explanation by admitting that he deferred releasing it "primarily because it's so gosh darn hard to explain." Basically, though, vim-abolish is a collection of utilities for search and replace within Vim: abbreviation (word completion), substitution, search, and coercion (case change). What makes vim-abolish especially powerful is that it can work with different forms of a word – not only upper and lower case, but also different tenses, added prefixes or suffixes, and variants in spelling.
The R statistical programming language can handle any statistical challenge you throw at it. It knows about information arranged in tables, and can calculate means, variances, correlations, and many other summary statistics. With supporting libraries it can produce graphic plots in 2D and 3D. Perhaps its greatest strength is its Comprehensive R Archive Network (CRAN), a repository of thousands of packages that allow users to move comfortably in and between statistical domains.
The GNU Compiler Collection (GCC) is easy to use, but it offers so many command-line options that no one can remember them all. Here are five uncommon command-line options you can use to get the most out of GCC.
Often times, huge web projects use multiple programming languages and even multiple databases. While relational database management systems (RDBMS) are common, they have limitations when it comes to the management of highly variable data. For such applications, NoSQL databases are a better alternative. The PostgreSQL RDBMS now provides Foreign Data Wrappers (FDW) that let PostgreSQL query non-relational external data sources.
