Rockmongo Error: "Deprecated: preg_replace(): The /e modifier is deprecated"

If you're using a recent release of PHP and you see the following error message in the Web UI -


The full error reads - "Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in /Library/WebServer/rockmongo/rock.php on line 449"


Edit line 449 in rock.php and change

$name = preg_replace("/_([a-zA-Z])/e", "strtoupper('\\1')", $name);

to read -

$name = preg_replace_callback("/_([a-zA-Z])/", function($m){return strtoupper($m[1]);}, $name);

Then restart apache.

An Ideal Boy

Image
Thanks to Chapati Mystery , one of my favourite blogs, I came across ' Adarsh Balak ', an art project by Priyesh Trivedi . It's a satire on classroom posters from my childhood. Most of them were badly illustrated and seemed to have been designed by people with little education and even less imagination. Unfortunately it's satirical only if you grew up privileged and had the benefit of a private education. So it's really just an in-joke for the upper-middle class. There are some examples of these posters below, after the art work. In the piece below, the large word in the background spells 'Swag' in Hindi and the chain around his neck says 'YOLO'. Based on the alphabet posters. This one says (pretty much) ' T for Toke'. 'Adarsh Balak' is translated as 'An Ideal Boy' in the poster below. This is still a top selling poster (my guess is that Williamsburg is their biggest market) for the  Indian Book Depot , whi...

Automated Testing with vncdotool (Not Headless, but Hairless)

Image
The headless testing problem is a thorny one and impacts the fundamental architecture of the test automation platform I'm working on. If we can't find a solution, we might not be able to use the private cloud nor parallelize our testing effectively. Part of the problem are the tests themselves that still rely on SendKeys() and MouseMove(). Two aspects of remote interaction that are insecure and therefore disallowed by Microsoft from Windows Vista onwards. This means that we have to rely on hacks like the VIX API and the one that I am about to document below. There are two widely-used technologies for remote interactive connectivity on the Windows platform - the Remote Desktop Client (RDC) and VNC. The first is entirely proprietary while the second offers a number of open-source implementations (and some proprietary, full-featured, commercial implementations). The RDC implementation requires access to the VIX API which in turn relies on proprietary, privileged access t...
