Just finished 'le premier jour' not bad at all. I will wait a while before reading the 'la premiere nuit'. I find the story a bit uneventful though, by that i mean i was expecting more 'interiorisation' of the characters. It read like a fast pace grisham.

And of course gave R12.1 funnier behaviours. Transactions not completing..select count(*) from obj took ten minutes etc. So, when you create a SAN be careful on how the file system is created, use RAD10 or RAID5 only (or others with stripping option). <br /><br />Another hint, upgrade OCFS to latest version, but be warned ocfs version must be same as the kernel version. uname -a for kernel version and rpm -qa | grep ocfs for ocfs.<br /><br />good luck..it took us ages to get that one right.Hansley Chadeehttp://www.blogger.com/profile/14424989404093835786noreply@blogger.com0tag:blogger.com,1999:blog-2824446424906128064.post-9494736057662375732010-07-11T08:53:00.002+04:002010-07-11T08:57:32.288+04:00Struggling.<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.kerryr.net/images/pioneers/gallery/leibniz3_lg.jpg"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 191px; height: 266px;" src="http://www.kerryr.net/images/pioneers/gallery/leibniz3_lg.jpg" border="0" alt="" /></a><br />I am having a hard time getting through the <a href="http://en.wikipedia.org/wiki/The_Baroque_Cycle">baroque cycle</a>.

It is a mythological and historical lanscaping of the american myth. It requires some 'erudite' knowledge of world history. <a href="http://www.neilgaiman.com/works/">Neil Gaiman</a>, is a good author, the book is well written, intelligent, astute and somewhat melancolic. It is a goodbye to the old world and a wlecome to the new world, but only to certain extent. Is shadow the 'king' ? I am not sure, but he is merely someone who is honest enough to the whole world. The wifey role is well tantalising, this is love beyond the grave. But, the icing on the cake is how she died with a **** in her *****... for well, friendship sake.

Test of Oracle 11g on it (not certified as of 08/04/2008).Hansley Chadeehttp://www.blogger.com/profile/14424989404093835786noreply@blogger.com0tag:blogger.com,1999:blog-2824446424906128064.post-71727619239065610312008-04-12T17:51:00.004+04:002008-04-12T17:57:53.384+04:00The Road.<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://ecx.images-amazon.com/images/I/21E8H3D1JSL._SS500_.jpg"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 200px;" src="http://ecx.images-amazon.com/images/I/21E8H3D1JSL._SS500_.jpg" border="0" alt="" /></a><br />I got that <a href="http://www.amazon.com/Road-Cormac-McCarthy/dp/0307265439">book </a>after reading a review from <a href="http://www.salon.com">salon</a>.<br />I thought this item was about survival, indeed it was, but the writing was so nihilist that i went numb after a while. Although the scenery was not repetitive i wonder how bad it meant to portrait an unknown catastrophy. Finally no clue on what happened in the world, but it looks to be a neutron bomb war of some kind or some solar eruption of some kind killing all life. probably the latter rather than the former.Hansley Chadeehttp://www.blogger.com/profile/14424989404093835786noreply@blogger.com0tag:blogger.com,1999:blog-2824446424906128064.post-5277962277990071462008-03-09T16:10:00.001+04:002008-04-12T18:03:17.814+04:00scared Sh1t !<object width="425" height="355"><param name="movie" value="http://www.youtube.com/v/Ov1wlc0zGMQ&hl=en"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/Ov1wlc0zGMQ&hl=en" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object><br />I used to be scared <a href="http://www.sonypictures.com/homevideo/30daysofnight/">before</a>..watching stuff like blair with project, read salem's lot etc. But, i was in for a ride with that one.
