PDF remains the best file format for sending, sharing, printing and archiving electronic documents. While its universal formatting and viewing features are unsurpassed, it is not so convenient for making changes. So, as much as we like receiving documents in PDF because we know we’ll be able to view the document as intended, with all the text, images and hyperlinks in their proper places, we get a headache when we receive a PDF that we need to modify. In many cases people start creating new documents and manually typing information from the PDF file in order to get the job done.

To simplify the process of editing PDFs, there are PDF manipulation tools created for different purposes: to convert PDF documents into MS Excel spreadsheets, to convert PDFs into PowerPoint presentations, to allow typing in the PDF itself, to allow making bookmarks in the document, etc. Many of these tools focus on one specific feature of a PDF manipulation, like converting PDF into Excel, for example, and they are often free and online.

There are, however, more advanced tools for PDF conversion and editing with more than one conversion option and we are sharing one such free online PDF Converter here today.

The advantage of this tool over many other free online converters is in its comprehensive nature: it can create PDFs from over 300 different Windows formats, as well as convert PDFs into the most used Office suite formats: .doc, .xls and .ppt.

hdparm is a powerful command-line utility for Linux and Windows operating systems to set and view ATA hard disk drive hardware parameters. The utility also allows users to test disk read/write performance with cached and buffered modes. The utility allows users to view and change SATA/IDE disk-drive hardware parameters like drive caches, sleep mode, power management, acoustic management, and DMA settings which are generally set to suboptimal conservative defaults to their optimal settings for best performance. Checkout the example output below for disk information command followed by disk performance test.
