    Dealing with the various ways Rails and jQuery can interact is....interesting. I finally figured that if I want to respond in format :js, versus :json, my form/anchor need to have the HTML5 data-type data selector set to "script" for the resulting JavaScript to be processed and executed.

    Otherwise it assumes the returned data is json, not executable JavaScript...and since the render action of my Characters#create action responds with a .js.erb file that contains the template to append to the table, JSON isn't what I wanted in that case.

    Yes, it is.

    @Infidel: Basically it's going to be a PA D3 socializing site, with a way for people to request items to be crafted, and schedule pick up games with fellow PA players. Essentially it's an excuse to write a big Rails project and do something cool for the PA D3 community at the same time.

    This new part time job I got...the employer has a good relationship with my campus's excellent Career Services program, so that puts me at ease.

    It's not just that they want a PHP shopping cart (though they do want one), but are there software solutions out there for catalog/shopping cart software for tablets/iPad devices?

    For a shopping cart? Just build a decent PHP one.

  • GnomeTankGnomeTank Registered User regular
    Blarg...you can't put forms inside table rows in HTML and have them play nice, so I have to re-think the entire characters list. I'll have to make it using divs.

    This is an old quirk and you simply do forms like this:
    <form><table><tr><td><input ...></td></tr></table></form>
    

    Remember that forms aren't actually layout elements so it is fine to break the layering "man this looks wrong to me" thing.

    Yeah, I know. The problem is I need one for for each row, because they send to different REST URL's. it's fine, I have Twitter Bootstrap on my side, I'll just use divs. I was just being lazy.

    No, you can do 2D with Unity. You just have to understand the fact that even 2D games today, are really 3D games, just using an orthographic projection, and projecting textures on to camera facing planes, generally represented as quads. The days of mode 13 and writing directly to surfaces is mostly gone.

    You can do this yourself using just raw Unity, but there are also some Unity plugins that make wrap some of that in to a nice friendly API and workflow.

    (Sorry for the somewhat late reply, Diablo 3 and all that.)

    Oh, wow, I hadn't thought of that. Thinking about it, that's kinda how XNA does it as well, huh.

    I'm interested in doing a tile based application (ok, I'll admit it -- a tile based game) to keep myself sane while I look for work now that I'm out of College. I was going to use XNA but apparently Unity lets you port to IOS and Android too? Anyway -- what are some of these Unity plugins you mentioned for 2d stuff? Anything specific for tile based games?

    I really need to shore up my programming skills. I've taken first year programming classes in a dozen different languages (and the single Data Structures class my latest College offers), but have no idea how to turn that into something a business might need. Just fiddle around I guess.

    @KiTA: I don't remember the name of the plugins off hand, but if you go to the Asset Store built in to Unity, you'll see them listed there, a long with a bunch of free and paid assets you can use to start building a game.

    Does C# have an equivalent to Python's random.choice() which, returns a random item in a sequence, or do I have to roll my own?
    Looking in the Random class it looks like all it can spit out is numbers, but I didn't know if there was somewhere else that had one.

    You can do IEnumerable.ElementAt(Random.next()%IEnumerable.Count) to get the same effect. There may be a smoother way of doing that, though...

    EDIT: If list order doesn't matter you could do IEnumerable.Shuffle().Take(1)

    Is there a good IDE for assembly programming? I've been using plain old notepad and fixing problems as the compiler finds them, but that seems a little more awkward than necessary. And assembly is already more awkward than necessary.

    If under Windows, the good old standby remains Visual Studio.

    Which type of assembly programming are you doing? Just certain functions in assembly, or entire apps in assembly?

    If doing certain functions/parts of functions in assembly, the easiest thing is probably to use inline assembly, and then debug using the Debug->Windows->Registers window with the Debug->Windows->Disassembly window. Maybe use the memory viewer as well.

    If writing entire apps in assembly, I believe it is possible to set that up in non-express versions as well.

    Heh. People that need it have probably already moved to windbg already and can probably read the matrix.

    I get the impression that using the Visual Studio IDE/debugger is easy-mode. =P

    No, it's in Linux, and that's not something I can change.

    It's entire (small) apps.

    So far my default text editor is doing a decent job, but something that would help me keep track of how big variables are, make jump statements a bit clearer, and remind me when to use [varName] as opposed to varName would be appreciated.

    At the moment I can write a few hundred lines of x86 in half an hour and logically it all works, but then it takes me three hours to go through it and fix all the little mistakes I've made.

    Hey, everyone. Not A Programmer in the house here.

    I'm going to be starting an Associate Degree education in Web Programming (I can provide specifics if it's important) and I was wondering if I could get an idea of hardware requirements for a laptop. Right now my only computer is hooked up to my TV and there's no way I'm hunching in front of that for all of my class work.

    I can't imagine that the hardware requirements would be very demanding for those sorts of projects, correct?

    Also, how concerned should I be about being bad at math?

    For most programming you really don't need much more than +-/* and the occasional square root or exponent. Understanding binary is a good thing for programming in general, though it's probably not very relevant to web programming.

  • SmasherSmasher Starting to get dizzy Registered User regular
    An application I wrote has just been pen-tested within the past few months, so I've had compliance and security on the brain for a while now.

    Basically, SHA1 is next to useless now as there's so many rainbow tables for it available. What's recommended is doing recursive SHA256 hashing as many times as you can handle without affecting performance. Based on the build of the server I was working on and the speed of the language / framework I ended up with a 10,000 pass recursive hash seeded with a private key value and the current time in milliseconds. That satisfied the security company, anyway.

    Look into CSRF tokens / nonce values too -- they're exceptionally useful for increasing security at negligible cost.

    But, like others have said, even the most secure password hashing / security system in the world is only as good as the users using it. Even if you're storing data securely, there's nothing stopping people writing down their password or reading it out to someone over the phone who sounds professional.

    I want to ask a couple questions about your design decisions for my own edification, but some of them seem counter-intuitive to me so I'm not sure I'm understanding you correctly. Is this for hashing of user passwords for logging in, or something else?

    Thanks Phyphor and Bowen for you posts the other day. I've made some progress, but I'm having issues moving the second rectangle into the correct position while taking into account the first is rotated. I've neglected basic maths for too long!

    Here is a example of what im trying to get.

    29f7as2.png
    First rectangle is pre placed (blue), the user inserts a rectangle (red), red is placed in the flow with the blue matching its rotation.

    The top example fine and working. When I attempt to do anything where the first rectangle is rotated at all my workings go out the window. What should I be aware of that im forgetting?

    I have all data for the rects (position, length, height and rotation of both current and inserted.)

    I'm guessing your issue is matching the sides in a congruent fashion? Depending on where your origin point is (which part of the rectangle is the center/start) then all you need is simple additions to figure out where the start of the red one goes (adjacent to the blue one) and then rotate it.

    Yeah, this is for storing hashed passwords for users so they can log into a system.

    To expand upon this. Hashing is a 1-way form of encryption where you need to verify correctness rather than completeness, or you have sensitive data you don't want to store, but needs to be remembered.

    If you hash an array of bytes (files/strings) you'll get an output that should match it no matter where you go.

    "Hello my name is Steve" should be hashed the same no matter how many times you try it. So it's good if you need a quick way to go "this matches the input." Usually hashes are used for files and passwords because it's an easy way to see if they're compromised or match.

    The reason you use hashing for passwords is you don't want to store a password in plain text in a database (easy way to compromise a system) and there's really no reason to encrypt it, so, you don't need to reverse it.

    You hash "mypassword" and get the hash string of something like "3216fa4dba341bb4ae" and store that hash in your database. Then when a user logs in, you hash his password and see if it matches the hash. If it does, you're good. If it doesn't, it's the wrong password. Even a slight variation in capitals will cause that hash to be vastly different. Though depending on your level of hashing (SHA128 vs SHA256) you may have collisions of values.

    For instance "mypassword" might match the hash for "poopymcbutterface" thus allowing someone with that password in. You can semi combat this with salting as you basically shift how it calculates the hash. Public hash tables are a common thing, so, if someone compromises your database, and looks up hashes, if you don't salt the hash, and they know which hash function you use, your system is as good as compromised.

    Tell them you'd rather get it done in days instead of months and use a compiler. There's no good reason to ever write an entire program in assembly anymore
