<0> and i've heard .net 2.0 is the only way to fly <0> templates and incompletes and all kinds of joy <1> ChillAxen: um.. not sure <2> get what i mean though <1> unless you meant bitshift by bitpush <2> yep <1> but yes, you'd bitshift the larger masks into position and or them with the rest to get a composite bitmask <2> so as i build the bitmask it will first keep adding to say $output[0] till its full then start adding to $output[1] and so on <2> and on SQL i can jsut do a foreach of the bitmasks doign a push of bits and oring <1> so like 1101 and 1001 as two masks, to put them together to get 11011001 you'd 1001 | (1101<<4) <1> ChillAxen: i'm going to go ahead and say sure <2> mySQL mas is 8 bytes, which is 64 bits right? <2> max' <3> what do you need to use 64bits for? <4> yea <2> lol dam i explained that like 100 times fed. I have a list of on/off flags so im converting all these flags to a simple integer
<2> then from there it would be WAY faster for mySQL to just compare 2 numbers <2> then say have each onoff as a field to check <5> building a relational database using bitmasks is dumb <3> don't call me fed >:| <4> you can't sub-group all these on/off switches into groups less than 32? <1> ChillAxen: yes that's 64 bits <6> is there a way to have a tiff image on my hard drive to show as a valid resource with imagecopyresampled <2> kicken: i have no clue how many they will add later in life to this app <1> kicken: i've tried suggesting that several times now <2> which in essense isnt really that good either <6> when the img already exist <2> if they ever go over 64 <2> then it will outlive it's logic ;/ <4> i was just about to say that <2> but can you think of a better way? <1> ChillAxen: depends on your means of grouping them <1> if it goes over 64 bits, then your outliving your logic anyway by storing them all in one mask in the db <2> the example of this specific part is a restaurant database <1> the points is that the groups themselves should have their own db field as well <4> ChillAxen use your dreded joins? with the proper indexes and such it shouldn't be a problem. <2> and this is just storing different types of foods they serve <5> TheBomani: hmm looks like gd doesn't like TIFF <1> doing it with a db requires simply a linking table, and a 2 joins tops <1> but it's a lot slower <2> kicken: idk... if theres millions of hits a day <2> wouldnt that be ALOT slower <1> well, not a lot <1> oh i dont know <1> i'd have to bench mark it <2> two: yeh i know how to do joins with it, but im looking long term <5> ChillAxen: using a bitmask in a relational database is going to bite you in the *** later, use the model the way it's supposed to be used and you'll be happy <6> pizza: I know. Thats my prob right now <2> if it had millions of hits a day, this comparing 1 number instead of a **** load of left joins <2> it would be smart <1> it's not a ****load of left joins <1> it's 2 <1> always 2 <2> two: it then has to compare on every item in table 1 <1> you mean for each record? <0> i don't see anyone suggesting 33 columns of booleans yet <2> such as SELECT t2.* FROM restuarants as T1 where T1.id = T2.restaurant_id <0> why isn't anyone suggesting that yet <1> because you should not be enumerating multiple items as multiple fields in a table <2> jed: cause this is just a array they can customize <0> oh, customizable <1> jedzilla: because that's worse for scalability than ANYTHING else <2> yeh i did that already for bar opening times based on m-s <2> and i was hesatant to do it <2> brb <0> so between lack of scalability and complete udder disgusting code <0> the consensus is, "scalable!"? <1> uhh, 32 boolean fields (which would likely be stored as ints in the db anyway, wasting a ****ton of bits) would be even uglier to code <0> mysql has a boolean doesn't it <0> that's actually a bool <1> where bool1 = a OR bool2 = b OR bool3 = c, etc <2> not really jed <2> just a int(1) <1> i doubt it. prolly 4 bits <0> oh, poo on it, then <2> which still isnt a true Bool <1> er, 4 bytes
<0> no wonder i don't use it <2> cause a bool is just 1 bit <2> well two, the do have int(1) which is closer than that <2> but still not a true bool <0> $str = "\Unow this is just ugly\E"; <0> why am i learning perl? anyone? <2> lol <2> idk <1> we hardly ever use \U and \E in perl <3> if a bool is just 1 bit, then when it's false, does it just have no value? <0> it still exists <2> why when i went ot college did i have to learn cobalt -=/ <1> so? <0> kinda like, the klingons are in the federation, but they're still ugly <1> there are a ****ton of functions in php that exist that you'll never use <0> i love that '****ton' word <0> is that like 'bogon?' <2> fedt: idk... isnt 1 bit either 0 or 1 <0> 'bogosity' and 'quantum bogodynamics'? <4> I use tinyint(1) for bool's in mysql <1> heh <2> kick me too... <2> but still not a true bool <0> quantum ****tondynamics? <1> ****ton++ <3> yeah, that's right <2> cause it can still store 0-9 <2> so a bool of OFF is 0 <7> me four <2> and ON is 1 <7> just use it <2> or NO = 0 <2> YES = 1 <1> tinyint is 2 bytes, right? <4> could use an enum :) <3> or SOMETIMES or ALWAYS or NEVER <3> or MAYBE = .5 <2> Fedt thats not a bool then <3> :) i know <2> =] <1> he's being an ***, ignore him <2> its cool <3> i would just love to say php generate a "maybe..." <3> *see <1> no, it's pathetic <1> we're gonna take him out back and beat him with a hose <2> idk i might just store fricken 4 different INT fields <2> an d if they go over 32*4 **** them <1> i wonder how hard it would be, sql wise, to store them in a binary string <2> i dont think mySQL has that <1> might require a quick UDF to handle the data manip <2> cause thats waht i wanted to do lol <7> ChillAxen- you are storing "options" for each restaurant? <1> mysql has varchar, no? <2> yes varchar <2> they even have a varbinary <2> but thats different then binary's <1> that's all you'd need <1> it's data that's stored in binary form <2> Two-bits my idea was to take the same method im doing now <2> and store as a string <2> as apposed to int <1> using the quick string functions to get each char would effectively get each byte <1> not as a string of 1's and 0's though <2> care giving a quick example of what you mean? <1> build up a byte in the bitmask, chr it, add to string <0> Two-Bits, do perlmongers use qw() much <2> olinux: im really concentrating on this because it will be used for LOTS of different things <0> it seems like it could be a timesaver <0> @zip = qw(foo, bar, bing, bang); <1> jedzilla: for exports/inpurts mostly <0> er, foo bar bing bang <2> such as this restuarant tab has a list of optional food types they serve as one and another restuarant types <1> use Foo::Package qw(funcs that you want to use);
