I've been using InnoSetup. From a very simple version that I've got a few years ago it has grown to a full blown installation program. It support scripting, is multilangual, and there are aven a lot of design tools especially created for InnoSetup. So it is the obvious choice for me. But maybe there are alternatives.
There is microsoft, with their msi "technology" which is -as usual- very complex wihout much more features. I hate steep learning curves, so after a few tries, I decided not to use it. The concept is good: instead of writing procedural code, you just define what you need installed where, and it does the job for you. But getting rid of a procedural language should make the job EASIER, not HARDER. And there are no real benefits. So goodbye msi.
Then I investigated the "usual suspects": Wise and Installshield, the 2 top commecial installers available. Everybody with experience with both told me to skip installshield and go straigt for wise, because it was superiour. Because I had a legal version of wise 9, I tried it. But even this newest version has a windows 3.1 feeling, that you might get rid of with all kinds of patches and images, but in the end you are still stuck without normal Windows XP controls (like the green progressbar) And the wise "language" made me sick. If this is the commercial state of the art, then forget it and go straight to open source, because innosetup is way way superior over wise.
After this experience, I forgot about installshield. If this is not better than wise, it is not worth to investigate further.
And then there is NSIS. This is also open source, and is derived from the winamp installer. It is a comic farting lama counterpart of inno. It looks reasonalby good, at least as good as the wise installer, but also here you get a windows 3.1 feeling which goes away after a lot of "cosmetic" stuff.
Conclusion: Innosetup lives up to its expectations and is still my number one choice.

( 3 / 1173 )I've just finished a new version of the icelandic-horses website. Because it's a fairly large site, I decided to use tabs on top of the page, to make navigation simple and intuitive.
Just looking for what is available on the net, i found lots an lots of nice implementations, however, they all were very complex, used a lot of javascript or everything was done with images/tables. I wanted a PHP/CSS solution without images, and in fact, it turned out very simple, and looks like this:
;)
(no javascript and only 1 image used: a transparant dot (a gif file of 1x1 pixel, transparant)
Here is the class code:
class txtwebmenu {
var $objs; // all assigned objects
var $atxt = array();
var $aurl =array();
var $aopt =array();
var $nrobjs=0;
var $cursel="";
// additem - add a menu item,
// $item = the item ID
// $txt = default/normal image
// $url = jump-to url on select
function additem($item,$txt,$url="",$opt="") {
$this->atxt[$item] = $txt;
$this->aurl[$item] = $url;
$this->aopt[$item] = $opt; // options
}
// genmenu - the payoff: generate the whole thing
// $sel = item id of current selected item
function genmenu($sel="",$msize=2) {
if (strlen($sel)>0)
$this->cursel=$sel;
echo "<table border=0 cellpadding=0 cellspacing=0 width=100% bgcolor=white>";
echo "<tr><td height=3><img src='/ijs/gifs/transdot.gif' border=0></td></tr>";
echo "<tr><td>";
echo "<table border=0 cellpadding=$msize cellspacing=0>";
$ffirst=true;
reset($this->atxt);
while (list ($item, $txt) = each ($this->atxt)) {
echo ($ffirst) ? "<tr height=14><td class=twbspc><img src='/ijs/gifs/transdot.gif' border=0 width=6></td>" : "";
$target= (strchr($this->aopt[$item],"T") ? "target='_blank'" : "");
if ($this->cursel==$item) {
printf("<td class=twbmnuS align=center nowrap >");
echo "<a class='twbmnuS' href='".$this->aurl[$item]."' $target >$txt</a>";
}
else {
printf("<td class=twbmnu align=center nowrap>");
echo "<a class='twbmnu' href='".$this->aurl[$item]."' $target >$txt</a>";
}
echo "</td>";
echo "<td class=twbspc><img src='/ijs/gifs/transdot.gif' border=0 width=".($msize>1?"4":"2")."></td>";
$ffirst=false;
}
echo "<td class=twbspc width=100%><img src='/ijs/gifs/transdot.gif' border=0 width=1></td>";
echo "</tr>";
echo "</table>";
echo "</td></tr>";
echo "<tr><td bgcolor=#F2F1DD height=3><img src='/ijs/gifs/transdot.gif' border=0></td></tr>";
echo "</table>";
}
}
And here is the CSS. Acutally the whole "tab" look is done with borders in CSS:
TD.twbmnuS {font-family: verdana,arial,helvetica,sans-serif; font-size: 11px; font-weight: normal;
border-style:solid; border-color: #606060; background-color:#F2F1DD;
border-top-width: 1px;
border-left-width: 1px;
border-right-width: 2px;
border-bottom-width: 0px;
padding-left: 2px; padding-right:2px;}
TD.twbmnu {font-family: verdana,arial,helvetica,sans-serif; font-size: 11px; font-weight: normal;
border-style:solid; border-color: #606060; background-color:#DDDDDD;
border-top-width: 1px;
border-left-width: 1px;
border-right-width: 2px;
border-bottom-width: 2px;
padding-left: 2px; padding-right:2px; }
TD.twbspc {border-style:solid; border-color: #606060;
border-top-width: 0px; border-left-width: 0px; border-right-width: 0px; border-bottom-width: 2px; }
A.twbmnu:link {text-decoration: none; color: #164B56; xx: #567181;}
A.twbmnu:visited {text-decoration: none; color: #164B56; xx: #567181;}
A.twbmnu:Hover {text-decoration: underline; color: #000000; }
A.twbmnuS:link {text-decoration: none; color: #000000; }
A.twbmnuS:visited {text-decoration: none; color: #000000; }
A.twbmnuS:Hover {text-decoration: underline; color: #000000; }
And here is a sample how to use this class:
<?
$mo = new txtwebmenu; // a new tabmenu
$mo->additem('nr1','Item1',"item1.php?curmenu=nr1");
$mo->additem('nr2',"Item2","item2.php?curmenu=nr2");
?>
..html..
<? $mo->genmenu($curmenu); ?>
...html..
You could use separate php files for each tab-page, or use one "big" php file with all pages. With additem, you just supply the url of the page itself.
If you use separate php files, be sure to include the code above in every file (with an include)
The $curmenu var indicates which tab to highlight. Be sure to set it right, otherwise all tabls are grey

( 3 / 1054 )Changing from one editor to another... wow! An editor is a tool that i'm using so much, that changing from one to another feels like moving to another appartment.
On windows, I'm using homesite 3 for quite some years. Homesite 4 and 5 never attracted me: adding feature after feature to a product seldom makes it better. The new homesites were slower and less stable. So why change?
On unix, i'm using vi. But the reason for that is that its always available, and there are no alternatives, except for emacs, but that doesn't feel good. It has a steep learning curve, and i can't waste time learning an editor. On unix I stick with vi for a while.
But now, homesite 3 feels a bit outdated, and some issues are irritating.
So what are editor knock out criteria for me:
- stability. Losing a text file is not acceptable.
- lean and mean. Speed is essential
- correct tabs/indents. Most editors fail on this, create spaces instead of tabs etc.
- No silly mistakes with arrows and del keys. There are some simple rules that an editor needs to follow: backspace on the beginning of a line adds the line to the previous one, cursoring down may not change column position
- line numbers
- unlimited line length
- I like the homesite explorer-window on the left. It has become natural for me
- Multiple file editing, with one-click (tabbed) file changing
And a few nice to haves:
- ftp integration. Using an ftp-server as if you're working local (this is the reason I want to dismiss homesite3)
- overview/compression mode.
So I downloaded a few editors to see which one had it all. It turned out to be a dificult search:
Notepad++ - feel is good. However, no explorer toolwindow on the left.
Syn - No correct tab/indents. For the rest it seems ok
Jedit - ugly as hell (thanks to java), slow, no explorer window
MED - no correct tab/indents. Not lean and mean. Lot of useless stuff.
TexEdit - silly key mistakes. Does not feel natural. Bad indent/tab
Crimson - Feel is ok. No siilly mistakes. Tab/indent is a bit hidden, but the implementation is ok. It has a nice ftp feature, although not transparantly integrated it works ok. This is an editor that I will try for a while to see if it sticks.

( 3 / 923 )Oracle installations are always a pain, and on a non-supported distro like gentoo it will probably be much worse. Lets see what we get.
The oracle CD (9.2) contains a script called runInstaller.
* Create a user oracle and group oracle to run this script in.
* run runInstaller from the cd as user oracle
The default gentoo fstab for cdroms does not allow running scripts from cd.
You will get a bash: permission denied error, even if the file is x-r.
(Oracle uses a shebang to sh instead of bash (#!/bin/sh) in their script, so i was first on the wrong track checking the sh link (/bin/sh -> /bin/bash) but that was fine)
the reason is the gentoo folks advise you to put the 'user' option on the cdrom mounts. But this also implies 'noexec'.
You need to add 'exec' to the /etc/fstab cdrom mount line options:
/dev/cdroms/cdrom0 /mnt/cdrom auto noauto,user,exec 0 0
* You need to emerge lib-compat. If not emerged, you'll get an error because oracle can't find libstdc++-libc6.1.1.so.2
The next the error is:
Unable to load native library: /tmp/OraInstall2005-01-02_07-02-08PM/jre/lib/i386 /libjava.so: symbol __libc_wait, version GLIBC_2.0 not defined in file libc.so.6 with link time reference.
See if I can fix this one in the next post.

( 3 / 210 )after fiddling with mysql a bit, you normally want to use a real database. The limitations of mysql are numerous: no views, no triggers, no stored procedures and so on. For very simple applications its ok, but sql is more than just a select statement. Therefore someday you move over to oracle. Oracle software normally sucks, but their sql server rocks. Its very stable, scalable, unix oriented stuff.
Some do's and don'ts:
- never run oracle on windows. Its not stable (even less stable than windows itself). It is just not a good combination. You need to reboot it all the time (at least daily) due to memory leaks. Prepare for the worst if you're following this path.
- Never use other oracle software than their database server. Oracle forms? a joke. Oracle designer? sucks. Oracle installations: Always a pain. I have *NEVER* seen an oracle installation procedure without severe errors. (and that means over 7 years of oracle installtion history)
- Oracle databases are memory hungry. Start with 1Gb, then go up.
- After install, immediately tune up the server parameters. The defaults are not usable. Make your shared pool at least 500M for a 1Gb server, use large dbblocks (16k at least) If you don't do this, only 2 users can log in
