  • Learning Javascript in one weekend?

    - by dueyfinster
    Similiar to this question, I am wondering if experienced Javascript developers have any websites they use with examples to get the basics of Javascript down in 24/28 hours? I have looked at Douglas Crockford's Google Tech Talk and I bought the book "Javascript: the good parts" but I haven't had time to read it.

  • Many clients on a wireless AP for UDP broadcast packets

    - by distorteddisco
    I asked this question on StackOverflow and was directed over here, so I'd appreciate any advice. I'm deploying a smartphone application as part of a live music performance that depends on receiving UDP broadcast packets from a wireless access point. I'm guessing that between 20 and 50 clients will be connected at any one time. I'm aware that a maximum of 20 clients per access point is advised, but as the UDP broadcast packets are ground through the LAN, how would I be able to link multiple APs together? I'm looking for recommendations on a suitable AP for this. The actual data transmission rates are very low - only a few kB/s - as I'm just sending small messages to the smartphone apps, and there will be no WAN internet connection. I tried it with a few connected peers on an adhoc wireless connection without any problems, but ran into dropped packet issues on an old WRT54G running ddwrt, though it's in pretty rough shape. What's the best way to do this? I suppose I could limit concurrent wireless connections to 20 clients... but more would be nice. EDIT: I should also say that it's purely one-way communication; the smartphone application is only receiving broadcast packets, not sending anything.

  • Share your conky tips / scripts / .conkyrc

    - by Chad Birch
    I've just started tinkering with conky, and I'm hoping the StackOverflow crowd can share some of the cool things they've done with this tool. Scripts and .conkyrc files specifically geared towards developers would be especially good to see. Some good examples of developer-centric functions would be repository-monitors or heck, even something that monitors StackOverflow. Screenshots of what the functionality actually looks like would be appreciated as well.

  • What is the difference between a site and an app in Django?

    - by larf311
    I know a site can have many apps but all the examples I see have the site called "mysite". I figured the site would be the name of your site, like StackOverflow for example. Would you do that and then have apps like "authentication", "questions", and "search"? Or would you really just have a site called mysite with one app called StackOverflow?

  • Defined variables and arrays vs functions in php

    - by Frank Presencia Fandos
    Introduction I have some sort of values that I might want to access several times each page is loaded. I can take two different approaches for accessing them but I'm not sure which one is 'better'. Three already implemented examples are several options for the Language, URI and displaying text that I describe here: Language Right now it is configured in this way: lang() is a function that returns different values depending on the argument. Example: lang("full") returns the current language, "English", while lang() returns the abbreviation of the current language, "en". There are many more options, like lang("select"), lang("selectact"), etc that return different things. The code is too long and irrelevant for the case so if anyone wants it just ask for it. Url The $Url array also returns different values depending on the request. The whole array is fully defined in the beginning of the page and used to get shorter but accurate links of the current page. Example: $Url['full'] would return "http://mypage.org/path/to/file.php?page=1" and $Url['file'] would return "file.php". It's useful for action="" within the forms and many other things. There are more values for $Url['folder'], $Url['file'], etc. Same thing about the code, if wanted, just request it. Text [You can skip this section] There's another array called $Text that is defined in the same way than $Url. The whole array is defined at the beginning, making a mysql call and defining all $Text[$i] for current page with a while loop. I'm not sure if this is more efficient than multiple calls for a single mysql cell. Example: $Text['54'] returns "This is just a test array!" which this could perfectly be implemented with a function like text(54). Question With the 3 examples you can see that I use different methods to do almost the same function (no pun intended), but I'm not sure which one should become the standard one for my code. I could create a function called url() and other called text() to output what I want. I think that working with functions in those cases is better, but I'm not sure why. So I'd really appreciate your opinions and advice. Should I mix arrays and functions in the way I described or should I just use funcions? Please, base your answer in this: The source needs to be readable and reusable by other developers Resource consumption (processing, time and memory). The shorter the code the better. The more you explain the reasons the better. Thank you PS, now I know the differences between $Url and $Uri.

  • As3 help about addEventListener

    - by mydiscogr
    Hi, I've a little problem, I don't really understand if I can use addEventListener more than one time on the same object (and same callback function) if this case can I have a problem of overflow, or simple flex is so smart to not add again in the same stack same function for examples: var t:CServiceObj = _rModel.userGetBoardJoined(); t.addEventListener(EDataService.DATA_AVAILABLE,onDataOk); t.addEventListener(EDataService.DATA_AVAILABLE,onDataOk); t.addEventListener(EDataService.DATA_AVAILABLE,onDataOk); thanks

  • Multiple file selection for an upload control

    - by Abel Morelos
    Hi, I was trying to do something like this: http://www.element-it.com/Examples/MultiPowUpload/AdvancedHTMLinterface.html But in my search for information I found that is not possible to perform multiple file selection with simple HTML and JavaScript (and JSP in the server side). There is a way to do this without using Flash? A third party component you could recommend? Thanks.

  • restrict the scope of variables in a mysql query? with brackets?

    - by Haroldo
    I can't remember what the method is meant to be for ensuring the scope of a variable in a query is restricted to prevent mysql injection. where should i put brackets in the following examples? UPDATE table SET col_1 = '$var', col_2 = '$var2' WHERE col_1 = '$var3' and SELECT * FROM table WHERE WHERE col_1 >= '$var1' (Obviously looking for answers not using PDO!)

  • Can I use Dlphi to write to BDE an PHP to read from it?

    - by mawg
    I strongly prefer not to use additional 3rd party components, libraries or DLLs (at least in v1.0), unless there is absolutely no other solution. Question: (how) can I use Delphi to programatically crate a BDE database and write to it, then use PHP to read from it? Any URLs for examples of tutorial?

  • OpenGL - GL_FRONT versus GL_FRONT_AND_BACK

    - by Drew Noakes
    I'm tinkering with an open source project that uses OpenGL for rendering in 3D. In the construction of the materials I see code like this: // set ambient material reflectance glMaterialfv(GL_FRONT_AND_BACK, GL_AMBIENT, mAmbient); In other examples, this is used: glMaterialfv(GL_FRONT, GL_AMBIENT, mAmbient); So my question is, what is the difference here? Under what circumstances would it look different and, if my volume is enclosed with all normals pointing outwards, is there any performance difference?

  • jQuery: Circulate plugin: stopping midway in animation

    - by kelly
    Has anyone had any luck in altering the plug-in code so that one might animate an object in "3d" space for only a 1/4 or 1/2 turn? As it stands, an object must complete a full circle before stopping or looping. And for those who haven't seen it yet: http://css-tricks.com/examples/Circulate/

    I am unable to get this event to fire: $("#about").click(function() { //I have put alert("foo") here, won't fire $("#about_stuff").toggle(); }); snip <li ><a href="#a" id="about">About</a> I've tested the toggle line in Firebug and it successfully works - I am at my wits end, I've checked it against multiple examples and it persistently refuses to work.
