Taz Crawlers From Chinafschiettecatte

Thu, 07 Nov 2013 02:12:52 +0000

Continuing with experiences on the net another thing I have noticed are crawlers  operating from China (at least that is what their originating IP addresses are from). None are well behaved and ignore the robots.txt file, some are well written insofar that they are efficient, but most are not and will download anything and everything usually multiple […]

DDOS & Dumb Choicesfschiettecatte

Mon, 28 Oct 2013 15:09:32 +0000

Recently one of the sites I manage was subjected to a DDOS attack. It was not DDOS attack per-se, but someone wanted some very specific data from the site and thought it would be a good idea to contract it out to a ‘bot farm. The reason I say that they wanted some data was […]

Here is what I am currently working on:   New database to speed genetic discoveries » A new online database combining symptoms, family history and genetic sequencing information is speeding the search for diseases caused by a single rogue gene. As described in an article in the May iss…

Awesome xkcd cartoon today about the relative depths of lakes and oceans.

Baylor-Hopkins Center for Mendelian Genomicsfschiettecatte

And the other project I have been working on is a website for the Baylor-Hopkins Center for Mendelian Genomics. This website is designed to capture patient feature and DNA sample information for sequencing single-gene mendelian phenotypes. The site is not really for public consumption though.

OMIM – Online Mendelian Inheritance in Manfschiettecatte

Fri, 06 Apr 2012 12:34:10 +0000

For the curious, for the past 18 months I have been working on the OMIM website on-and-off. From the website: OMIM is a comprehensive, authoritative compendium of human genes and genetic phenotypes that is freely available and updated daily. The full-text, referenced overviews in OMIM contain information on all known mendelian disorders and over 12,000 […]

Flashback botnetfschiettecatte

Fri, 06 Apr 2012 12:28:45 +0000

This is probably the most ‘stable’ article I have read on the Mac Flashback malware exploit, ‘stable’ in the sense that there is no hysteria or hyperbole. The one thing I would add is that you should check all browsers as well as Safari: defaults read /Applications/ LSEnvironment defaults read /Applications/Google\ LSEnvironment defaults read […]

Google Please Don’t Crawl This Serverfschiettecatte

Thu, 16 Feb 2012 14:44:29 +0000

For some reason the Googlebot has found it necessary to crawl a development server of mine, I suspect that one of the users uses Google Chrome which probably snarfs urls browsed. Google tells us that one way to do this is to return the 410 HTTP  status code , and the way to enforce this in […]

Chromium OS Xfschiettecatte

Came across the Chromium OS X browser for Mac, guess it is an open source version of Google Chrome. Can’t really much difference between the two, but I will try it out for a while and see.

French Court Fines Google $660,000 Because Google Maps Is Freefschiettecatte

Thu, 02 Feb 2012 12:37:07 +0000

I am so glad I escaped France and that I am no longer French. Only in France could this happen, protecting a business whose model has been disrupted by a competitor. The sad thing is that this only benefits the incumbent, not its customers who could cut costs by shifting to a cheaper (free!) product, […]
