Apache & LDAP performance →
To let Apache search an LDAP tree, we use AuthLDAPBindDN and AuthLDAPBindPassword to bind during the search phase. But to increase performance, you should bind a test uid. For examples: AllowOverride None AuthName “Auth Name” AuthType Basic AuthLDAPURL ldap://192.168.0.1:389/ou=Users,dc=local,dc=host?uid AuthLDAPBindDN “uid=test,ou=Users,dc=local,dc=host” ...

Movable Type Finally Goes Open-Source →
Although it’s been long-expected, Six Apart finally transitioned its Movable Type blogging software to an open-source license today. In many ways this is a response to the success of Wordpress, the open-source blog-publishing software that is increasingly popular, especially among bloggers who like to tweak their own code. (TechCrunch uses Wordpress, for instance).
Now, Movable Type can benefit...
gddrescue: a tool for recovering data from damaged... →
Entry submitted by John Carlyle-Clarke. DPOTD needs your help, please contribute!
I wanted to recover data from a failing hard drive, and asked on IRC if any good tools existed for Ubuntu. Someone pointed me towards GNU ddrescue (named gddrescue in Debian and Ubuntu), which is designed for rescuing data from any file or block device.
Don’t confuse this with dd_rescue (package name ddrescue). GNU...

CLI Magic: A little script to customize directory... →
Sometimes when I run ls to get a directory listing, I am looking for a specific file, but I want to see the whole context where the file resides. While you can pipe the output of ls to grep, that doesn’t show you the whole directory with the matched files highlighted in a different color. I create a small script to do just what I want.

Directory listing with nginx ! →
For me, nginx is a great web engine. Just the simple way to do simple thing. It’s also easy to build and configure with advanced features. However, some built-in modules seem bad such as the autoindex built-in. Even turn it on, the directory listing seems not to work. But fortunately, instead of the built-in, nginx has a great modules to do that work fancily, that the fancy-index modules....

Loic is an accomplished entrepreneur - he founded uBlog (merged with Six Apart), organizes the annual Le Web conference and has now created Seesmic (note that I’m an investor in Seesmic). So even though he’s French, his advice, when given, is worth listening to.

Baseless Apple-Windows speculation →
Last week, Ars Technica posted “evidence that Mac OS X could run Windows apps soon”: Leopard apparently contains an undocumented loader for Portable Executables, a type of file used in 32-bit and 64-bit versions of Windows. More poking around revealed that Leopard’s own loader tries to find Windows DLL files when attempting to load a Windows binary. That’s nowhere near being able to “run Windows...

The three biggest community Linuxes are Fedora, OpenSUSE and Ubuntu. They’re all popular. They’re all good. But which is the best? Desktop Linuxes are improving so quickly that it’s hard even for someone like me, who tracks operating systems the way some people track their favorite NFL team’s game match-ups, to keep tabs on what’s what with the latest distributions....

Finding the right distro for my ThinkPad T61 →
I am a long time Linux user (almost 10 years), but I do not consider myself an expert by any means. I guess I would consider myself a power user. I started with a floppy disk install of Slackware. From there I moved to RedHat, Mandrake, Vector, and SUSE.
Hash Suffix Array Delta Compression on Linux →
Previous differential compressions have the following drawback: They do not find the best matches for every offset of the version file. IBM Hash Suffix Array Delta Compression combines hash value and suffix array techniques to find the best match with respect to a certain level of detail and above a certain length threshold.

Microsoft FUDwatch: Windows vs. Linux security →
It’s been at least a week since the last bout of Microsoft FUD hit the wires, so I guess it was time for a new wave. Today’s FUD comes from an article Microsoft released on how its security compares with that of Linux. It should come as no surprise that Windows comes off as the Second Coming while Linux is left on the wrong side of Acheron. It’s amusing to watch Microsoft attempt...

Six CHM viewers for Linux →
Even if you work only in Linux, you’ll likely have to use Microsoft Compiled HTML Help (CHM) files at one time or another. Several open source projects use this common format, including Apache, MySQL, PostgreSQL, Python, and PHP. Microsoft developed CHM as a proprietary format for Windows 98, leaving behind the previous WinHelp (HLP) format. CHM is still alive and kicking in XP and Vista,...
