  • Is MacBook powerful enough to do Ipad development? or do I need a MacBook Pro?

    - by ronaldwidha
    The title probably says it all. Considering an ipad's processor is nothing compared to a macbook, I would think a Macbook should be more than capable to run the simulator. However, not knowing much about iphone/ipad development, I'd like to get some opinions on this. for e.g. how many apps are typically need to be run for ipad dev (editor, debugger, perf monitor, trace log, etc). are these apps resource (memory, cpu) intensive? please do not take into consideration the actual image, 3d, video, sound development. I understand one would need quite a beefy machine to produce these type of creative assets. What I'm looking at is a machine to do code development, physics, putting together the produced assets (images, vector graphics, 3d video, sound, etc).

  • How is your mac setup for windows development?

    - by Matt Brailsford
    Hi Guys, I'm looking at buying a MacBook Pro to replace my tiring laptop. My day to day job is as a .NET web developer so I am looking to use VMWare Fusion to run VS and SQL server etc. As I've not run my dev environment in a VM before, I would like to know how others are setup. What apps to you have installed? In which environment? Where do you store your files? Within each environment, or some shared drive? Are there any gotchas? Or essentials I should know. Many thanks Matt

  • PHP - what is the proper way to do inline HTML variable output?

    - by edmicman
    I just moved from an Ubuntu PHP workstation dev environment back to Windows and am using xampp. I have a bit of code, like so: <input type="text" name="txtEmail" value="<?=$emailaddress;?>"/> that I swear worked to display the variable in the textbox when I was developing before. But when I loaded the page on Windows/xampp it just put that text between the quotes in the textbox. Instead, I ended up changing it to something like: <input type="text" name="txtFirstName" value="<?php echo($firstname);?>" /> The latter makes sense, but I guess I thought there was a shorthand or something, and I must be going crazy because I'm sure the first way was working on a difference environment. So what's the best way to do this?

  • Google App Engine - low-level datastore API flag?

    - by Keyur
    In my GAE-Java app, I'm using the low-level datastore API. Hence I don't need the GAE app instance to load any of the higher level data access libraries such as JPA, JDO, Data Nucleus, etc. Is there a flag that I can set to indicate that I don't want these libraries to be loaded? My motivation to do this is to reduce app instance startup time everywhere I can. Now I don't know if these libraries are loaded only on-demand or always. The dev environment logs messages related to data nucleus which seems to indicate that some of these libraries may be pre-loaded? I hope I'm wrong here. Thanks, Keyur

  • Embedding Youtube Videos on user's wall with the Javascript API

    - by dragonmantank
    I'm attempting to embed a Youtube video on a user's wall using the Javascript API. I've poured over a bunch of different tutorials and came up with this: var data = { method: 'feed', link: current_video_url, // Link to the vide on our site source: current_video_src, // Link to the Youtube video, http://youtube.com/v/[hash] picture: current_picture_url, // Thumbnail from youtube title: current_video_title, // Title from our page caption: current_video_description // Text from our page } FB.ui(data); Running the Facebook Debugger shows that the current_video_url link is being properly parsed for OG tags and is available as an embedded video. I ran a debugger and all the variables are being properly set in the data variable. This worked fine for about 2 days, and then we pushed the site live. We set up a new AppID in Facebook but now all the videos are just thumbnails instead of being embedded in the user's wall. I thought maybe this is a problem with the live site but now the dev site is broken too. What's the best way to get this to work consistently?

  • Django: tinyMCE and cross site javascript

    - by pistacchio
    Hi, follow this question, I was able to set some textareas in my admin page as richtext inputs. The most voted answer suggests to follow an example and is what i did. Also, it talks about a problem concerning "blank pages". I'm having the same problem and I'm not able to solve it. I have my media files served by a different server, so MEDIA_URL points to a different host with a different port. To simulate this in my dev environment, I also serve media files from a different port. Debugging the failing javascript, Chrome yelds: Unsafe JavaScript attempt to access frame with URL http://localhost:8000/admin/blog/post/add/ from frame with URL http://localhost:88/s3mangerie/js/tiny_mce/themes/advanced/image.htm. Domains, protocols and ports must match. How to solve this problem? Thanks

  • How would one use Cocos2d to create a game like this.

    - by John Stewart
    http://itunes.apple.com/us/app/angry-birds/id343200656?mt=8&ign-mpt=uo%3D6 So I am getting started with this all game dev thing on iphone and I decided that I will start playing with Cocos2d as my starting engine. Now just so i have a goal in mind, I picked angry birds as my initial target of what sort of game play would I like to learn to build. This is not going to be a market release game. This is totally going to be learning purposes only. So to start off my question is: Would something like this be achievable using Cocos2d? How would I go about building the physics for this? How can one do a screen scroll like the way they do in cocos2d? (any example code would be great) This is just to start off. If you have any particular questions please do add to this question.

  • Appengine not liking my .jspx files

    - by Hans Westerbeek
    I have a little app that runs fine on local dev appengine, but appengine itself is not processing my .jspx files. The jspx files are in WEB-INF so they should not be excluded by appengine (as a static resource) I am using Apache Tiles to define my views. So the html produced looks like this: <html xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:c="http://java.sun.com/jsp/jstl/core" xmlns:tiles="http://tiles.apache.org/tags-tiles" > <jsp:output omit-xml-declaration="yes"/> <jsp:directive.page contentType="text/html;charset=UTF-8" /> <jsp:directive.page isELIgnored="false"/> (etc etc) How can I solve this problem?

  • CKEditor Modal Issues.

    - by RavenHursT
    So I'm using CKeditor inside of a jQueryUI dialog. The issue I'm having is when you click on a button like the "link" button, the modal that pops up, won't let me type anything into it's inputs. I can change the values of the pull downs, I can drag the modal around the screen, and I can click on the buttons. But when I attempt to type into the text inputs, nothing happens. Has anyone else come across this? If so, did they find a solution? Thanks! Maybe this has something to do with it? http://dev.jqueryui.com/ticket/4309 But I'm using 1.7.2...

  • DB2 load partitioned data in parallel

    - by Erik Paulson
    I have a 10-node DB2 9.5 database, with raw data on each machine (ie node1:/scratch/data/dataset.1 node2:/scratch/data/dataset.2 ... node10:/scratch/data/dataset.10 There is no shared NFS mount - none of my machines could handle all of the datasets combined. each line of a dataset file is a long string of text, column delimited. The first column is the key. I don't know the hash function that DB2 will use, so dataset is not pre-partitioned. Short of renaming all of my files, is there any way to get DB2 to load them all in parallel? I'm trying to do something like load from '/scratch/data/dataset' of del modified by coldel| fastparse messages /dev/null replace into TESTDB.data_table part_file_location '/scratch/data'; but I have no idea how to suggest to db2 that it should look for dataset.1 on the first node, etc.

  • Access block level storage via kernel

    - by N 1.1
    How to access block level storage via the kernel (w/o using scsi libraries)? My intent is to implement a block level storage protocol over network for learning purpose, almost the same way SCSI works. Requests will be generated by initiator and sent to target (both userspace program) which makes call to kernel module and returns the data using TCP protocol to initiator. So far, I have managed to build a simple "Hello" module and run it (I am new at kernel programming), but unable to proceed with block access. After searching a lot, I found struct buffer_head * bread(int dev,int block) in linux/fs.h, but the compiler throws error. error: implicit declaration of function ‘bread’ Please help, also feel free to advice on starting with kernel programming. Thank you!

  • Advice needed: What tech expertise do I need to accomplish my goal?

    - by quaternion
    I have a business plan & money to hire a developer - the essentials involve simple online games for children (played via traditional computer over the internet) such that their scores are uploaded to a database that can be viewed via a nice portal. What I don't know is: what technologies I would want my developer to know (the only somewhat unusual requirement I have is that the games have relatively accurate timing of keypresses/mouse presses) how much I should expect to pay (in general, what is the appropriate range) how many hours a program of the complexity of a simple tower defense -type game should take to develop (to be clear, the idea is not to implement TD, but rather other games of similar complexity) whether I should go with capable acquaintances, some online kind of online web-dev bidding site, or just try to find a capable undergraduate at the local university who I can wow with his/her first big paycheck, how I should communicate the software's specifications to my hired developer... Is there a standard I should be using? whether I should hire a webdev consultant for a few hours to help me answer these questions, instead of asking stackoverflow Thanks for any advice!

  • Cross-compiling a Python script on Linux into a Windows executable

    - by Chinmay Kanchi
    I have a Python script that I'd like to compile into a Windows executable. Now, py2exe works fine from Windows, but I'd like to be able to run this from Linux. I do have Windows on my development machine, but Linux is my primary dev platform and I'm getting kind of sick of rebooting into Windows just to create the .exe. Any ideas? PS: I am aware that py2exe doesn't exactly compile the python file as much as package your script with the Python interpreter. But either way, the result is that you don't need Python installed to run the script.

  • Mercurial clone operation works, but I don't have write access

    - by normalocity
    Somewhere I did something silly. I was deploying my Rails app via cloning the Mercurial repo down onto my Ubuntu server. It worked the first time, and then...well, I made a small change on my dev machine, pushed the changes to the repo, and then deleted the copy on the Ubuntu server and re-cloned from the repo. The clone operation (the second, and third, and 'n' times) works without error, but I don't have write access to the files that were cloned. When I try to startup my mongrel - it can't create the /tmp folder, and because of no write access, fails to start the Rails app.

  • Ampersand in link description text?

    - by kitenski
    I am validating my site using validator.w3.org and have an issue where there is a & in my link description text. ie this is taken from the source <a class='tag' href='/php/iphone software.php?function=developer&amp;dev=witch%26wizards+inc.&amp;store=143441'>witch&wizards inc.</a> Which gives me this error in the validator Line 188, Column 540: cannot generate system identifier for general entity "wizards" …6wizards+inc.&store=143441'witch&wizards inc. If I urlencode the description then the validation passes, but the user then sees the text displayed urlencoded, ie Developer witch%26wizards+inc. However I believe it's much more user friendly if this was displayed unencoded, ie Developer witch&wizards inc. Is there a way to pass validation but still have user friendly text displayed? Thanks, Greg

  • Query size of block device file in Python

    - by ??O?????
    Hello. I have a Python script that reads a file (typically from optical media) marking the unreadable sectors, to allow a re-attempt to read said unreadable sectors on a different optical reader. I discovered that my script does not work with block devices (e.g. /dev/sr0), in order to create a copy of the contained ISO9660/UDF filesystem, because os.stat().st_size is zero. The algorithm currently needs to know the filesize in advance; I can change that, but the issue (of knowing the block device size) remains, and it's not answered here, so I open this question. I am aware of the following two related SO questions: Determine the size of a block device (/proc/partitions, ioctl through ctypes) how to check file size in python? (about non-special files) Therefore, I'm asking: in Python, how can I get the file size of a block device file?

  • Registry corrupted for testing?

    - by Emile
    Hi. Forgive my ignorance. I'm a lowly LAMP stack developer and this is my first post for "c++". We had an Internet Explorer add-on commissioned but then lost support. Allegedly each version has to be have been tested "on a fresh computer since old add-ons could have cause registry errors." I'm not familiar with IE add-on development (or c++ dev). Is this common? Can't one simply reverse registry errors? How to continue testing iterations on one machine? Thanks!

  • Examining mmaped addresses using GDB

    - by Mikeage
    I'm using the driver I posted at http://stackoverflow.com/questions/647783/direct-memory-access-in-linux/ to mmap some physical ram into a userspace address. However, I can't use GDB to look at any of the address; i.e., x 0x12345678 (where 0x12345678 is the return value of mmap) fails with an error "Cannot access memory at address 0x12345678". Is there any way to tell GDB that this memory can be viewed? Alternatively, is there something different I can do in the mmap (either the call or the implementation of foo_mmap there) that will allow it to access this memory? Note that I'm not asking about /dev/mem (as in the first snippet there) but amount a mmap to memory acquired via ioremap(), virt_to_phys() and remap_pfn_range()

I wonder if this is my mistake or I do need to do something? this is what I did: Downloaded from mysql site: http://dev.mysql.com/downloads/mysql/5.1.html#macosx-dmg I choose : Mac OS X 10.5 (x86_64) I run all the packages and installed all of them. So now I certainly have mysql in /usr/local/mysql/ But when trying to start it from preferences panel, it is always STOPPED. When I try to do (in the terminal): /usr/local/mysql/bin/mysql I got : -bash: /usr/local/mysql/bin/mysql: Bad CPU type in executable What is wrong here? Any help would be very appreciated. Thanks
