Ubuntu is composed of many software packages, the vast majority of which are distributed under a free software license. The only exceptions are some proprietary hardware drivers.The main license used is the GNU General Public License (GNU GPL) which, along with the GNU Lesser General Public License (GNU LGPL), explicitly declares that users are free to run, copy, distribute, study, change, develop and improve the software. On the other hand, there is also proprietary software available that can run on Ubuntu. Ubuntu focuses on usability, security and stability. The Ubiquity installer allows Ubuntu to be installed to the hard disk from within the Live CD environment, without the need for restarting the computer prior to installation. Ubuntu also emphasizes accessibility and internationalization to reach as many people as possible.

5 quick tips to help keep your website secure.

Tuesday, August 12, 2014

1. Start with Your WordPress Username.
When installing a new version of WordPress, one of the first steps is to select your username. Because it comes up with the default of "admin" many users overlook changing this and continue on with a very lame, hacker-attack-waiting-to-happen username. I know - I did it too way back when.

I'm willing to bet that your name is not "admin", only guessing here but I'd wager that your first name may be more difficult for a hacking robot to come up with than "admin". So my advice is to use your first name or a name associated with your site.

In addition, this also makes your site appear more personable as your name will appear next to your post heading and date unless you turn off those features. It also shows up in the comments and that definitely is friendlier.

Rawdog is an RSS Aggregator Without Delusions Of Grandeur.

Rawdog is an RSS Aggregator Without Delusions Of Grandeur. It is a "river of news"-style aggregator: it uses feedparser to download feeds in RSS, Atom and a variety of other formats, and (by default) produces static HTML pages containing the newest articles in date order.

 

Rawdog is designed to be invoked periodically by cron (or a similar task-scheduling mechanism). It stores data in flat files, so no database is required. It can use threads to download multiple feeds in parallel, and uses ETags, Last-Modified, and gzip compression to minimise network bandwidth usage.

rApache Web Application Development with R and Apache: Handler Return Values and HTTP Response Codes (Chapter V).

Saturday, July 19, 2014

It is a list of lists, with the nested list giving you the "name" of the file and the "tmp_name", the location of the temporary file. For instance, to reference the uploaded file from the input tag named "FirstFile" you would use FILES$FirstFile$tmp_name. Here's a code snippet to copy the file to the '/usr/local/uploaded_files' directory:

 

destination <- file.path('/usr/local/uploaded_files',FILES$FirstFile$name)
file.copy(FILES$FirstFile$tmp_name,destination,overwrite=TRUE)

 

NOTE: the temporary files are deleted after the R handler completes handling the request. Thus, it is imperative that you copy/move this file to your desired location before the R handler returns.

rApache Web Application Development with R and Apache: Difference in r-handler and r-script (Chapter IV).

The latest Apache2 debian packages cause the web server to run in a very reduced environment, thus one is unable to set LD_LIBRARY_PATH before calling /etc/init.d/apache2. One option is to actually edit that file and add the LD_LIBRARY_PATH explicitly. Another is to use the apache2ctl scripts which are also bundled with the debian packages. Or you can add it to /etc/ld.so.conf.

4.6 sendBin.

Sends binary data to the browser. This function is equivalent to R's writeBin() function, but the connection argument is ignored. See the documentation to writeBin() in your R distribution for more information.

rApache Web Application Development with R and Apache: Difference in r-handler and r-script (Chapter III).

Rapache is a simple tool for remotely managing and configuring an apache2 server.

If you need a simpler software just to start/stop apache2 and mysql, check localhost-indicator.

 

3.6.2 Difference in r-handler and r-script.

r-handler, r-script, and r-info are valid arguments to Apache's SetHandler directive ("r-info" is already described in section 2.3). Calling SetHandler forces url's to be parsed through the named handler.

 

r-handler is used when you want to call an R function without arguments. You can also specify a particular file as well (see below). It is generally used within Location directives.

 

Currently we don't have a dedicated website.

SquirrelMail is a standards-based webmail package written in PHP.

Wednesday, July 16, 2014

SquirrelMail is a project that provides both a web-based email client and a proxy server for the IMAP protocol.

 

The webmail portion of the project was started by Nathan and Luke Ehresman in 1999 and is written in PHP.

 

SquirrelMail can be employed in conjunction with a LAMP "stack", and any other operating systems that support PHP are supported as well. The web server needs access to the IMAP server hosting the email and to an SMTP server to be able to send mails.

 

SquirrelMail webmail outputs valid HTML 4.0 for its presentation, making it compatible with a majority of current web browsers. SquirrelMail webmail uses a plugin architecture to accommodate additional features around the core application, and over 200 plugins are available on the SquirrelMail website

 

The SquirrelMail IMAP proxy server product was created in 2002 by Dave McMurtrie while at the University of Pittsburgh (where it was named "up-imapproxy", although it has become more commonly known as "imapproxy") and adopted by the SquirrelMail team in 2010.

NetSurf is an open source web browser which has its own layout engine.

Tuesday, July 15, 2014

NetSurf is an open source web browser which has its own layout engine. It is designed to be lightweight and portable, supporting both mainstream systems (e.g. Mac OS X and Unix-like) and older or uncommon platforms (e.g. AmigaOS, Haiku and RISC OS). NetSurf has many typical web browser features, including tabbed browsing, bookmarks and page thumbnailing.

 

The NetSurf project was started in April 2002 in response to a discussion of the deficiencies of the RISC OS platform's existing web browsers. Shortly after the project's inception, development versions for RISC OS users were made available for download by the project's automated build system. NetSurf was voted "Best non-commercial software" four times in Drobe Launchpad's annual RISC OS awards between 2004 and 2008.
