POSIX compliant Unix file permissions can be reinforced by additional filesystem protections called “file flags” on FreeBSD. In addition to standard Unix file permissions, FreeBSD offers an additional layer of file-level security that applies to non-directory files, known as “file flags.” File flags can be used even to prevent the root user account from altering or deleting files — something that POSIX compliant Unix file permissions cannot do...  

There's a nasty upstream bug in GTK present in Ubuntu 9.10 that makes Eclipse Galileo all but unusable -- specifically it makes clicking many buttons with the mouse just stop working. You can use tab and spacebar to make it work, but that's not much of a workaround. All you need to do is set an environment variable before starting Eclipse: export GDK_NATIVE_WINDOWS=trueread more

And now, for a list of Linux commands i always forget about: To get the GUID of a drive (so that a given hard drive ALWAYS mounts up under a given directory): blkid /dev/drive (and insert into /etc/fstab as: UUID=UUID mount path ext3 defaults 0 2 To compare two different directories: diff -rq dir1 dir2 > dirs.diff To copy ginormous [...]  

Just a quick posting of some simple benchmarks today.  Please note, these are not the be all, end all performance results that allow everyone to scream from atop yonder hill that Solaris performs better than Linux!  This was just me doing a little due dilligence.  I like Solaris 10, and wanted to run it on our webservers.  We're looking at using NGINX to serve up some static files, and I wanted to make sure it performed like it should on...  

We are looking for an experienced Unix Systems Administrator. The ideal candidate will have a minimum of 4 years experience in supporting Linux/Unix in production environments. Candidates must have impeccable written and verbal communication skills and have a minimum of 4 years experience with direc...  

if you've changed that to 30 or 45 or higher number but still get the error, change it to 0. 0 means that no timeout limit. 'timeout' => apply_filters( 'http_request_timeout', 0), If by using that way you still get the error, you need to contact your administrator because I think that your server connection is not good.  

Here’s a great article about Unix turning 40 years old. The article takes you back to late 60’s when Ken Thompson and Dennis Ritchie joined Bell Labs to its current state where three manufaturers dominate the Unix world of HP-UX, Solaris and AIX. Many of us still remember that Byte Magazine article in 1990 that wondered [...]  

Installing OpenVPN on Linux and Unix Systems: Part 1 Thursday, December 3, 2009 | Linux Servers Installing OpenVPN is easy and platform independent. Modern Linux systems, such as SuSE, Red Hat, Debian, or Ubuntu, provide sophisticated installation and package management systems, and still offer other ways to install the software. In this two-part article by Markus Feilner, we will install it on different Linux versions and FreeBSD...

With the recent explosion of cloud computing services, developers now have more opportunities than ever to take advantage of enterprise-scale computing platforms. However, most cloud computing services, such as Amazon's Elastic Compute Cloud (EC2), have unique and incompatible APIs. This has provided a challenge for organizations wanting to develop in-house applications that can later be seamlessly deployed directly to Amazon's service when...  

As an HPC cross platform developer, I have spent a good part of my 20s working on scientific codes under different operating systems.  Windows, Mac, LINUX, HPUX, AIX, IRIX, Solaris.  Building /compiling code is a full time job, not to mention porting and making changes due to the API differences.  This is what I call the #ifdef jungle. In any case, I found a group of 3 musketeers, that shared my pain, and we would like to save you time when...  

We just learned that when you insert a UNIX_TIMESTAMP into MySQL that it will keep the UTC version of the timestamp, which is good. However, when you use FROM_UNIXTIME() to convert your Unix timestamp into a datetime string, ...  

GnuPG is available in Solaris starting with build 130.  OpenSolaris users can pull the latest packages from the /dev repository by looking for SUNWgnupg and SUNWpth packages.   GnuPG is a complete implementation of the PGP protocol (RFC 4880) with an open source license (GPL).  I will not enumerate all of its many features here, the GnuPG website has plenty of good information.  There are even a set of HowTo documents to help you get started...
