with distributed computing, and parallel computing
were my favourites... and here I am programming for the Web... I guess
it's distributed ;)
Cheers,
Rob.
Todd and Rob:
I understand.
But, I'm more inclined to agree with Rob, I actually *DO* miss
Algorithms and such. There are great minds out there and it's nice to
be able to touch their genius.
As for favorites, I liked digital filters, FFT, ray theory, computed
surfaces, and all versions of AI. I even developed an algorithm to
explain why migrating birds fly in a V formation. Some exciting Geek
stuff.
But here I sit programming the web and following a client's
instructions I don't like that 'Buy Button' in blue, make it red. I
feel like a 45 that's being used to swat flies. But hey, we all can't
be born rich and most of us have to work for a living. At least I
have work. :-)
Cheers,

You only want to sharpen that image if the rest is easy on the eyes too.
Some things are better left grainy.

I find if I read stuff on a black background, I start seeing fuzzy
streaks. I do use a light grey to edit in though.
Be cool to see screenshots of people's set-ups. The light grey is the
only alteration I've ever made from BBedit's default settings.

what Robert suggest, is something exactly what the big-big photos
gallery out there used
to store their image. Distributing the image into many servers. But i
am not very sure, how
they store the image location information inside the database.
But i like the idea of using imageUId to determine where to store the image.
I think, storing image in a bucket with 100 images each can make the image
more
manageable..
thanks for that idea..
That physical location on the hard drive just needs to be a
configuration variable for the site. As long as all the servers use the
same physical path, then it's a no brainer.

Re: [PHP] include_path, permissions question
O/H dg ??: Hello, I'd greatly appreciate some help with some problems I'm hitting. I have a site set up on a dev server and it works fine. In transferring it to the clients server, it's getting all weird. When I first transferred created files, the owner was joe. And they worked fine. When I republished those files using fwrite, the owner changed to httpd. And includes and file_get_contents stopped working. I tried changing the owner, but couldn't. I changed include_path. I turned on error reporting and got: Warning: include(includes/common.php): failed to open stream: Inappropriate ioctl for device in /**/local/home/**/dev.**.net/alb**acl.php on line 5 Warning: file_get_contents(): SAFE MODE Restriction in effect. The script whose uid/gid is 398/398 is not allowed to access includes/lyrics_box_scripts.txt owned by uid/gid 191739/191739 in /**/local/home/**/dev.**.net/alb**acl.php on line 11 Thanks in advance for any assistance. -dg I think that a file stores a userid not the user so if for e.g. you have a user in your system that has id 1001 and you move this file preserving the rights to another computer the owner will become the user that has userid 1001 on the new system. In case there no user having the 1001 id then you will see just 1001 on the ownership when you ls. In case you don't preserve the rights of the then I think that the user that copies/moves the files takes the ownership of the files. Since I believe that you are a unix user man cp on you system to see what is the switch for preserving rights (it is -p on Linux if I recall correctly) an make sure the same user gets the same id (usually happens for apache. On the other hand you may just simply change the ownership recursively like chmod -R apache:apache dir which is much easier. -- Thodoris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] apache/vhosts wuestion...

[PHP] date() and strtotime()
Hello everybody,
I hope you all have a nice day, mines not that good 'cause i have encountered a
strange problem.
i have a few functions to work with dates. they are all very simple, a few
lines of code.
this first one does just gives you the monday of the current week:
function get_monday($date) {
$input_date = strtotime($date);
$date_array = date_parse(date('r',$input_date));
$get_sunday = 7 - $date_array['relative']['weekday'];
$day_label = date(D, d.m.y,mktime(0, 0, 0, date(m) ,
date(d)+$get_sunday, date(Y)));
$new_day_label = strtotime($day_label);
$monday = date(D, d.m.y,mktime(0, 0, 0,
date(m,$new_day_label) , date(d,$new_day_label)-6,
date(Y,$new_day_label)));
return($monday);
}
now for testing purpose we say today is friday, 11.07.2008, this function
returns correct Mon, 07.07.08.
now the problems lies in the second function or more in strtotime.
this second function just takes the inputed date and does some formating so it
will fit into
the mysql db or query.
function get_mysql_date($date) {
$old_date = strtotime($date);
$new_date = date(Y-m-d,$old_date);
return($new_date);
}
But now the strange thing happening is, this function outputs '2008-07-14'
which is monday of the next week.
now i think the problems lies somewhere in strtotime(), cause if i do this:
$dateForTable = $date_class-get_monday($today);
$dateTest =strtotime($dateForTable);
$dateTest2 =date('r',$yousuck);
it will also output 'Mon, 14 Jul 2008 07:07:08 +0200'.
i think strtotime() takes just the first part 'Mon' and looks what date the
next monday is.
i'm realtivly new to php so any help solving this problem will be greatly
appreciated.
thanks alot to all.

Here's the point of your comfusion. ParkingSpace is not really a
ParkingLot is it? I mean you could say a parking lot having a single
parking space qualifies, but not really. I see you problem being similar
to apples versus apple tree. You wouldn't do the following (would you?):
?php
class AppleTree
{
}
class Apple extends AppleTree
{
}

Re: [PHP] Question regarding OO
Object-oriented programming, with it's class and object approach,
is meant to model real life more closely than functional programming.
In, a parking space is physically inside a parking lot, but a
parking space is not a subclass of a parking lot. It's not a variation
or mini parking lot. It's an entirely different entity. A parking lot
consists of parking spaces, but a parking space is its own thing.
In other words, don't extend ParkingSpace from ParkingLot. They should
be separate classes entirely.
As for the recursion... no, that won't be a problem. Each ParkingSpace
you're instantiating is a separate instance, and won't be related to
the parent ParkingLot in anyway way internally.
?php
class ParkingSpace {
var $size;
var $num_spaces;
var $spaces = array();
}
class ParkingSpace {
var $ps_ID;
var $occupied_by;
var $st_time;
}
?
In the above class definition, simply populate the $spaces array with
instances of the ParkingSpace class.

Listen to what everyone else has said so far. Look up IS-A versus

to have spaces, but spaces don't have to be in a parking lot.

Then, with improved filesystems, the limit was rumored to be another magic number: 65535. That depended on the operating system, filesystem, and the kernel. I think (but don't quote me on this) that BeOS had the 65535 limit. Now, on an ext3 filesystem (we're not counting ReiserFS because (1) I was never a fan, and (2) he might kill me if I say something bad! 8^O) you're okay with hundreds of thousands of files per directory. ls'ing will be a bit of a pain in the ass, and if you're in Bash, you probably don't want to double-TAB the directory, but all in all, you'll be okay. Still, I'd create 16 subdirectories under the images directory: 0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f. Then name the file as an MD5 hash of the image uploaded, and place it in the directory matching the first character of the new file name. Aren't directory structures in Windows (2.x) and even DOS (4.x) built with B-Trees? I wouldn't figure there would be any kind of limit--excepting memory, of course--to how many files or subdirectories can be linked to a single node. Been a while since I've played with those underlying data structures we all take for granted, though, so maybe I'm way off base. They may all be B-Trees but the storage mechanism often differs between one filesystem and another. FAT16 and FAT32 both suffered from limitations on the number of files that could exist in a directory. Actually, I may be wrong about FAT32, but I do know for certain it had massive slowdown if it hit some magic number. tedd also sent me an e-mail that sparked a memory of mine... the b-trees, regardless of their efficiency, still assign each dir/file INode an identifying number. This number, obviously, can only get so large in the context of one b-tree object (i.e., a directory). In spite of this mental exercise, I do *NOT* miss my Data Structures Algorithms class. :) Really? That along with distributed computing, and parallel computing were my favourites... and here I am programming for the Web... I guess it's distributed ;) Don't get me wrong--I enjoyed the class very much. I had never seen sorting algorithms outside of the Bubble Sort, so learning Pivot, Shell, etc. was quite a blast. Self-balancing data trees and such were a real eye-opener as to the power of data structures, too. I'm just... glad I don't have to learn it all over again in a classroom environment. :) Haven't taken a distributed computing class just yet, but I've still got a bit until I graduate, and these elective credits are burning a hole in my pocket...

Self-balancing data trees and such were a real eye-opener as to the power of data structures, too. Self-balancing data trees were one of my favorites -- I even wrote a Macintosh application showing the operation of a splay binary-tree, as seen here (for those who have Macs): http://sperling.com/freeware.php A splay is based upon how often a search is preformed for a specific item. The more often the search, the closer the item appears toward the top of the tree -- thus less time to find it. The up and downside of the splay is that the tree is balanced each time a search is preformed -- requiring more time to balance it, but less time to find the item -- kind of a trade-off that works for some situations. I am sure that many search engines use a similar approach. I'm just... glad I don't have to learn it all over again in a classroom environment. :) Not me, I would love to be in a classroom again.

I deal with local colleges a bit -- taught a few classes. Recently our local Community College (LCC) decided to return to their previous database. They tried using Oracle for about six years, but they could never get it to work and finally gave up. Unfortunately in the process, they spent over $20 million dollars, which included a help desk that cost over $650,000 per year, and everything failed miserably. They simply didn't have the experience and no one would admit that they didn't. Instead of hiring local talent, the board of trustees sought out experts from NYC who encouraged them to throw even more money at the problem. You see, NYC has all their colleges running on Oracle, but they also have over 200 full-time Oracle programmers working on it. It wasn't until the Federal government threaten to hold up government money (because the college wasn't paying students their grant and other monies) that the college wised up and retreated from their We're just like NYC attitude. Sometimes, these smart people aren't as smart as they think they are. Cheers, tedd PS: BTW -- I offered my talents but they didn't have the professional curiosity to even reply.

It can be any computation you want that produces a number -- such as just totalling the number of letters in the name. For example, tedd.gif would compute to 4, whereas Rob.gif would be a meager 3, and Daniel.gif would be a six (which is probably over-rated for him anyway). :-) Now, just use our respective number for storage in directories -- tedd.gif would be stored in directory 4, Ron.gif would be stored in directory 3, and Daniel.gif in directory 6. If you store the names of the files in a database, then you don't need to store the paths as well because the paths can be computed from the file names -- do you see? Also, you don't need to create a directory until there's actually a need for one. This is old logic for creating memory structures where we weren't forced to allocate memory beforehand -- it's like a large array with holes in it. It's kind of slick when you can apply it to other stuff. Now, the example I gave was pretty simple. However, a good hash algorithm is one that distributes things evenly, and that's a bit more complicated -- I'll leave that for another time. now returning you to your normal television viewing pleasure :-) Cheers, tedd -- --- http://sperling.com http://ancientstones.com http://earthstones.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
