03:16 mikemol I've added rel=nofollow sitewide.
03:16 TimToady what does that mean?
03:17 sorear I think that tells honest spiders to stay away
03:52 opticron do you keep stats on what percentage of spiders are honest?
03:59 mikemol rel=nofollow is a bit of metadata added hyperlinks that tells search engines not to use an association between the link source and destination in calculating the relevance of the link destination in searches.
03:59 mikemol In short, it prevents the link target from benefiting from the reputation of the site containing the link.
04:11 sorear is that only for external page links, or for all hyperlinks on the site?
04:14 mikemol Should only be for external links.

09:50 Axtens[RCo] Hello
09:50 ttmrichter Hello.
09:51 Axtens[RCo] Are we getting inundated with spam accounts? Is it something I can do anything about, or do I leave it to admins to deal with?
09:59 Axtens[RCo] for example, I just noticed that Vismhwditasnkb had posted a lot of spam, so I replaced the entry with {{remove}}
09:59 Axtens[RCo] is there anything else I should have done?

11:14 nnzed is there a channel for newbies ? eg just trying to make this simpile http://awk.freeshell.org/awk.exe
11:14 fedaykin "AwkChannelWiki: awk.exe"

12:13 ttmrichter nnzed: Weren't you banned?

12:39 mikemol nnzed: There is only one channel. This is fine.
12:46 nnzed mike - just need some new people to try that page on - eg is it too detailed - is it clear why i mention three different awks ? etc
12:50 mikemol Don't look at me...if you think it might require more information, add more information. :)
12:53 nnzed just looking for input from someone that might find that page useful - eg the experts already know all that

13:05 mikemol There are a few programming subreddits that may be of use. Perhaps /r/awk
13:05 nnzed how about rossetacode re http://mathworld.wolfram.com/CliffRandomNumberGenerator.html

15:03 nnnzed not pretty but think this works http://dpaste.com/hold/1205047/
15:04 fedaykin "dpaste: #1205047: _Cliff_rand(), by g0ph3r_"
15:08 ttmrichter nnnzed / g0ph3r_: Why are you so fascinated by that function?  Between that and your "log accuracy" thing you're verging on OCD.
15:12 ttmrichter In addition, the code you put up on dpaste is not the same as the code shown in the gawk manual nor is it the same algorithm as displayed at mathworld.
15:13 nnnzed was just Trying to find a function that Gave the SAME randon values in Any version of awk - in spite of the version / base code or compiler - Think i Have done it ??
15:13 ttmrichter No, you haven't.
15:13 ttmrichter What you want to do is not possible.
15:13 ttmrichter Please, really, try and get it through your thick head: you cannot make floating point that is universal.
15:14 ttmrichter Run your floating point code on a VAX and watch everything change.
15:14 ttmrichter Short of writing your own floating point library that implements your own floating point format with semantics that you control at the lowest levels, you're not going to get what you want.
15:15 nnnzed Have tested that code in both awk / gawk /mawk - seems to give the same values for the first 1e6 values
15:15 ttmrichter (Repost for comprehension): Run your floating point code on a VAX and watch everything change.
15:15 ttmrichter http://docs.oracle.com/cd/E19957-01/806-3568/ncg_goldberg.html
15:15 fedaykin "What Every Computer Scientist Should Know About Floating-Point Arithmetic" http://rldn.net/VJc7
15:15 ttmrichter Read that paper.
15:15 ttmrichter Understand that paper.
15:15 ttmrichter Until you do, anything you say on the subject of floating point just makes you look dumber and dumber.
15:16 ttmrichter (Hint: problem #1 is that YOU CANNOT EXPRESS 0.1 PRECISELY IN ANY BINARY FLOATING POINT SYSTEM.)
15:16 ttmrichter So any Awk implementation that sits on an architecture that uses, say, BCD in its floating point representation will automatically not match.
15:17 ttmrichter No matter how many bizarre, pointless and self-defeating gyrations you try to insert into the code to "make it the same".
15:17 ttmrichter It.  Will.  Not.  Work.
15:17 ttmrichter Read.  Understand.
15:21 nnnzed in your insane want to bash me - you Never Read my code - i truncate every calculation at 1e8 eg only a few bits of a double precision float number - so Any cpu or computer should be able to do that correctly ???
15:23 nnnzed btw all awk uses double precision float for numbers - Not BCD
15:25 nnnzed anyone else here that can tell me where i am wrong ?
17:11 nnnzed bbl its late - catch u later
18:05 opticron ugh
