  • Custom warning in Xcode

    - by maximumnamelength
    I'm working on an API library and I'd like to add a few warnings that would appear when another developers builds the app if an optional apikey is not included. It should be buildable w/o the key (since it's optional) so I can't just add a syntax error to force a build error. I know Xcode supports TODO and FIXME but those aren't really highlighted anywhere major. Any other thoughts on how to approach this?

  • Is it possible to make JQuery keydown respond faster?

    - by Drew Paul
    I am writing a simple page with JQuery and HTML5 canvas tags where I move a shape on the canvas by pressing 'w' for up, 's' for down, 'a' for left, and 'd' for right. I have it all working, but I would like the shape to start moving at a constant speed upon striking a key. Right now there is some kind of hold period and then the movement starts. How can I get the movement to occur immediately? Here the important part of my code: Your browser does not support the HTML5 canvas tag. start navigating coords should pop up here key should pop up here var c=document.getElementById("myCanvas"); var ctx=c.getContext("2d"); //keypress movements var xtriggered = 0; var keys = {}; var north = -10; var east = 10; var flipednorth = 0; $(document).ready(function(e){ $("input").keydown(function(){ keys[event.which] = true; if (event.which == 13) { event.preventDefault(); } //press w for north if (event.which == 87) { north++; flipednorth--; } //press s for south if (event.which == 83) { north--; flipednorth++; } //press d for east if (event.which == 68) { east++; } //press a for west if (event.which == 65) { east--; } var msg = 'x: ' + flipednorth*5 + ' y: ' + east*5; ctx.beginPath(); ctx.arc(east*6,flipednorth*6,40,0,2*Math.PI); ctx.stroke(); $('#soul2').html(msg); $('#soul3').html(event.which ); $("input").css("background-color","#FFFFCC"); }); $("input").keyup(function(){ delete keys[event.which]; $("input").css("background-color","#D6D6FF"); }); }); </script> please let me know if I shouldn't be posting code this lengthy.

  • Extern variable at specific address

    - by AndiNo
    Using C++ and GCC, can I declare an extern variable that uses a specific address in memory? Something like int key attribute((__at(0x9000))); AFAIK this specific option only works on embedded systems. If there is such an option for use on the x86 platform, how can I use it?

  • when to index on multiple keys in mongodb

    - by Evan
    say I have an Item document with :price and :qty fields. I sometimes want to find all documents matching a given :price AND :qty, and at other times it will be either :price on its own or :qty on its own. I have already indexed the :price and :qty keys, but do I also need to create a compound index on both together or are the single key indexes enough?

  • How do I best catch up with the latest developments in java?

    - by Fredriku73
    I am applying for a job as java developer. I programmed some hobby apps in java until 2001, after that I have mostly worked in c++ and other languages. Meanwhile, it feels like java has grown a lot, and there are all kinds of acronyms (EJB, spring, etc) unknown to me. Where can I find a concise, clear explanation of the recent (5 years) development of java? What are key elements to understand?

    - by marpo_it
    I am trying to open a remote shell via ssh to send commands from R. As long as I send commands, I need to get results and send new commands that depends on the output of the previous ones. For this reason I am looking for a solution to open a connection and manage it from within the R code until I have finished. I also need to open the connection with ssh key exchange (so without password authentication). Looking at CRAN I didn't find anything useful.
