Static HTML templating
by Mark Rogers 08 Apr '10

08 Apr '10

I'm (fairly) sure someone here was talking about a templating system for generating static HTML (ie you write the templates, run a script, and get a set of HTML that you upload to the website). I can't find it by searching my ALUG archive for phrases like static, HTML or template, though. Does anyone recall what it was? If not (or regardless), does anyone have any recommendations? I'm building a website for someone who will need to maintain the static HTML themselves when finished. Since all the pages have common elements it's a pain not templating it for my own benefit, however. I could just work in PHP/Smarty as I normally would, then "wget --mirror" the site to generate the static HTML, but if there are better solutions I'm always happy to learn something new! -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Slow network performance with lots of connections
by Mark Rogers 08 Apr '10

08 Apr '10

When my Linux box has a lot of connections (eg when downloading an ISO via BitTorrent), the network connectivity gets very slow for other things. Now this could be because the total bandwidth usage is high, but I'm seeing this even when the total bandwidth on my cable connection is say 50kbps down, 10kbps up. As this is cable, I may be hitting Virgin bandwidth limits (I'm not sure how to tell), and this may sometimes be the case because if I test with another PC on my home network I sometimes find it is also slow. Other times the other PC is fine. In any case, killing the torrent download usually (not always) speeds everything up. So, there seem to me to be several possible issues (any/all of which may be applying at different times), but I don't know how to diagnose it. For example, it may be the total number of connections at the router (a cheap Netgear wireless cable router supplied by Virgin), or maybe even at the virgin cable modem box? I try rebooting any of these and sometimes it works, sometimes it doesn't, but I am very aware that I'm just trying random things and not really getting anywhere! -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

It was Ant by the look of things. In the end I added: ANT_OPTS="-Xmx1024m -Xms1024m" export ANT_OPTS to /usr/share/ant/bin/ant and it appears to have fixed the problem. -- Thanks Paul Paul Grenyer e: paul.grenyer(a)gmail.com b: paulgrenyer.blogspot.com

MySQL Arrrgg!
by James Bensley 06 Apr '10

06 Apr '10

Knowers of all (I have cross-posted this question to two different lists hence the BCC to not cause unwanted traffic so reply either on list or directly to me off list, its your choice); I am trying to execute the following MySQL statement and am coming up a croppa' SELECT name FROM `visitor` WHERE dob = DATE_SUB(CURDATE(), INTERVAL 21 YEAR) This is to select everyone from a table who is 21 years old, just as an example. The statement runs and returns with no errors but returns no entries (and there are entries that are 21 years old) Ultimately I am going to do something like this (I am just free-writing this so the syntax is probably wrong but hopefully you will get the idea); SELECT name FROM `visitor` WHERE dob BETWEEN DATE_SUB(CURDATE(), INTERVAL 21 YEAR) AND DATE_SUB(CURDATE(), INTERVAL 30 YEAR) to get everyone who is between X and Y years old. Do people think the problem is in my statement or my database? -- Regards, James. http://www.jamesbensley.co.cc/

Fwd: [Gllug] Open Source Hardware - event & list.
by Richard Lewis 06 Apr '10

Hi ALUG, I know there are a few very keen hardware geeks reading this list. The following may be of interest. I guess meetings will be in London, but the list <http://oshug.org/cgi-bin/mailman/listinfo/oshug> may be quite fun. Of course, there's also the question of whether LUGs should splinter off hardware enthusiasts; after all, hardware is pretty useless without software and software is pretty tedious without hardware. -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Richard Lewis ISMS, Computing Goldsmiths, University of London Tel: +44 (0)20 7078 5134 Skype: richardjlewis JID: ironchicken(a)jabber.earth.li http://www.richard-lewis.me.uk/ -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +----------------------------------------------+ | Support open access to scholarship | | http://freeculture.org/ http://www.doaj.org/ | +----------------------------------------------+

Increasing Tomcat Memory
by Paul Grenyer 04 Apr '10

04 Apr '10

Hi All I've installed Tomcat 6.0 on my build server running ubuntu 9.10. I followed the instructions here: http://www.howtogeek.com/howto/linux/installing-tomcat-6-on-ubuntu/ And it's been working well. However, I think my application has got too big now (lots of third party JARs) and I keep getting out of heap space on deploy. I've googled but I'm struggling to find a way to increase the memory that works. Can anyone give me some pointers, please? -- Thanks Paul Paul Grenyer e: paul.grenyer(a)gmail.com b: paulgrenyer.blogspot.com
