<0> haha
<0> ex wife
<1> heh wish I could.
<2> oh right
<2> What to do if -- experienced in Java but not enterprise Java
<2> employers want J2EE
<0> yep
<2> and not just the fact that you could easily handle J2EE once in the job
<2> they want proven delivered projects on J2EE
<1> its significantly different
<2> sure, i realise
<1> just because u can do J2SE is no guarentee u can perform with J2EE
<2> Its a killer
<2> I can't get the experience without working on a job
<2> and because of my age.. noone seems to want to employ me as a junior
<1> :-/
<1> I was lucky to be taken on as a J2EE dev only knowing a bit of J2SE
<1> but then I'd just left uni
<2> Yes. that is the thing
<2> I've heard back from one recruiter
<1> just keep trying I suppose
<2> Saying.. he had a position but the employer said something like "harder to teach an old dog new tricks"
<1> and get yourself some training under your belt if u can
<2> ok.. now that's where you might be able to help guide me
<1> java certification etc
<2> I've been struggling with that for a while
<1> java.sun.com plenty of tutorials
<2> Sure
<2> It's a tough situation
<2> I'm minding the kids
<2> I've little free time.. my wife won't mind letting me off the hook from minding the kids if I have a job to go to
<1> :-/
<2> but in the meantime.. I've not enough time to study for certs,etc
<2> She doesn't understand the industry
<2> I was looking into doing masters at Uni
<2> I've got one from years ago (but its not in CompSci)
<2> however, I am a bit worried that a 2 yrs masters could leave me further out of the loop than I am even at the moment
<2> I mean.. what would an employer make of a masters degree ? .. they measure a lot based on work , projects
<1> get yourself some tutorials etc
<1> do some example work
<1> and then stick it on your cv
<1> and hope for the best
<2> What do I need ideally in terms of hardware to do this work ?
<2> To do something meaty and not a farty little j2ee example
<2> What is the ideal development platform in your opinion for doing some prototype development
<1> majority of apps will work on a standard desktop quite easily.
<2> yeah but in terms of a backend db,etc
<1> whilst using an IDE, Tomcat, JBoss, Oracle etc
<1> just ensure u have plenty of RAM, 2GB maybe, and a general modern spec.
<1> then delve into http://java.sun.com/javaee/5/docs/tutorial/doc/index.html
<2> Oracle.. shikes.. I need a license for that
<1> no the express edition u dont
<1> anyway mysql will suffice for the beginning
<2> oh right.. that is useful
<2> yeah mysql
<1> http://www.oracle.com/technology/products/database/xe/index.html
<2> As I mentioned an issue is time.. I have to convince my wife that I need time to do this
<2> She thinks more traditionally... she'd be ok with me going to university to do a course
<2> but she would view that as just tinkering around at home
<1> see if u can find one tailored to it then
<1> off home, adios
<3> if i have 2 matrices of 1's and 0's can I use the & operator to create a new matrix?
<3> or do I have to & each index on its own?
<3> erhm, each cell
<4> i don't get that
<3> u don't get what i asked?
<3> or something else...
<4> yes.. i don't get that
<3> well, lemme explain what i'm trying to do
<4> ok shoot
<3> i am trying to do collission detection
<3> and i know that using black/white pictures (black meaning no object, white meaning object)
<3> i find the overlapping sections of the pictures and cut them out, then i compare them for pixels that overlap
<3> 0 = black, 1 = white
<3> i don't wanna traverse every pixel one by one through that image, instead i was hoping there'd be a faster way
<3> i just don't know how to work binary images, how to read the data in big lumps, which is what i really wanna do
<4> i see..
<3> so i thought i'd preload all the data into a matrix of 1's and 0's and be able to use & on the two matrixes to see if any of the outcome would be 1 (white pixel on top of white pixel)
<3> but that fell through
<3> someone already said i can't do deepcopy or something
<3> so i'd much rather know how to read in a binary (bilevel) image instead
<3> whoo
<4> hmm...
<4> i think there's no better way than that
<4> wait..
<4> give me time to think
<3> i don't mind comparing the images 1 pixel at a time, but if i can read the image in every 8 bits it'd be much more efficient to do an & operator every 8 bits, i think
<3> isn't it?
<4> yes yes
<4> wait.. what do you mean deepcopy?
<3> no idea
<4> haha
<3> i asked in dalnet #java and they said what i asked wasn't possible
<3> and said something about deepcopy, not sure what deepcopy has to do with what i'm asking
<3> i guess the & operator isn't made to look at the item of each cell in a matrix, but rather just the address of the cells
<3> regardless, the best thing to do would be to able to read each image in 8,16,32 or 64 bit buffers
<3> then do the &
<4> well I agree with doing it by reading it by power of 2 bits
<4> wait.. im searching over the net to get a good picture of your problem
<3> i found lots of stuff talking about binary/bilevel images, but none about reading the data out of them
<3> if need be i can do it 1 pixel at a time
<3> that's not hard, u cut the proper areas of the images out then compare 1 pixel at a time to see if it's on/on
<4> errr... if you could do it 1 pixel at a time why not do it by that?
<3> if i'm comparing 30 objects for pixel collision it'd take up a lot of cpu
<5> o.O
<5> JFreeChart totally rocks
<3> i know in VisualBasics u can AND the 2 images to create a new image, but the new image still has to be scanned for pixels
<5> $ wc -l ChartTest.java
<5> 22 ChartTest.java
<5> In 22 lines, I can display an XY plot of a database query!
<4> just a thought.. why not read the entire thing first and store it on a variable then use & operator
<4> that would sure cut the cpu cycle down
<3> read the entire image?
<4> you could do it in partial
<4> although, i don't really now how to do it but the idea is there
<3> that's what i wish to do, read it in buffers of 8,16,32 or 64 bits
<4> errr.. what is stored again in your matrices?
<3> the matrices idea is out of the window since it won't work regardless
<3> and the more i think about it i'd have to read in each pixel 1 at a time anyways
<3> and store it to the matrix
<3> then &, which is dumb
<3> but a bilevel image is just 1's or 0's so if i can read in 64 bits (or pixels) at a time that'd be great
<4> hmmm do you need to know the place of the bit where the colision occured?
<3> no, but it'd be useful for the future
<4> hmmm...
<3> just the fact that a collision occured would be the most important
<4> hmmm...
<3> this would be a ton easier if it wasn't pixel collision
<4> here's just my idea..
<4> you could read the first 8bits of the first image store it on a variable..
<4> then read the first 8bits of the second image again store it on a vairable
<4> then use & to check whether there's a collision
<4> errr.. sounds stupid?
<4> ahaha
<4> just a thought
<3> no, that's what i wanna do
<3> i wanna read the images in 8,16,32 or 64 bits
<3> just don't know how
<4> errr...
<6> 64 bit color information?
<3> well, color is a bit much, just black/white images
<6> what is meant by "read images in 64 bits"?
<3> i have 2 images i wanna do a pixel comparison of
<3> just black/white images, black is off and white is on
<6> what does "black is off and white is on" mean?
<3> well, the color black represents a "false" pixel and white is a "true" pixel
<3> basically i look at 2 images, if there are 2 white pixels in the same x,y location then the entire thing is true
<6> is that really related to comparing images pixel by pixel? or is that not what you want to do?
<3> well, pixel by pixel is the long way
<3> if i can compare 64 pixels at once
