  • I can't find a DirectX installer to run from my installer.

    - by John
    I tried this one. But it's the annoying one which asks you where to extract temp files, my users won't know what this means. I also tried the web installer, but you're not strictly allowed to use this. I don't really follow the windows setup stuff, but is there a single .EXE I am allowed to distribute and run, which just works (for DX 9.0C) with some command-line args? Or some other way, which can can described in idiot-proof steps and and called in one command-line argument from an installer script like Inno?

  • Should we use Nexus or Artifactory for a Maven Repo?

    - by John Stauffer
    We are using Maven for a large build process ( 100 modules). We have been storing our external dependencies in source control, and using that to update a local repo. However, we are ready to graduate to a local repo that can cache central so that we don't have to proactively download all 3rd parties (but we can still have a local repo to pull from). In addition we want to publish our internal build artifacts from a nightly build so that developers don't have to build the world. We are considering Nexus and Artifactory. What are the reasons for preferring one over the other? Are there others we should be considering?

  • PHP PDO Username Availability Checker

    - by John Bernal
    I'm building a registration page that uses JQuery's validator plugin to validate the form. For the username, i used the remote method. So here's my jquery+html code: fiddle And here's Available.php: <?php $usr = $_POST["username"]; $link = new PDO('mysql:***;dbname=***;charset=UTF-8','***','***'); $usr_check = $link->prepare("SELECT * FROM Conference WHERE Username = :usr"); $link->bindParam(':usr', $usr); $usr_check->execute(); if($usr_check->rowCount()>0) echo "false"; else echo "true"; ?> So I have a test account in my database with the username: user. When I tried to submit my form with the same username, it didn't display the error saying "username taken" which means the php isn't correct. Any ideas where I went wrong? Thanks

  • SVN: change a past revision and have the change in current

    - by John Isaacks
    ok say I am on revision 4. I check it out, make some change and commit it. I am not on revision 5. I check it out again, am making some changes, but I am informed that there was a typo from revision 5 that needs to be changed right away. I don't want to fix it in my current working copy because I am in the middle of something and it wont be ready to commit yet. But I don't want to revert back to revision 5 and loose all my work. what I want to do is go back to revision 5, make the small change, commit it. And ALSO have that change made to my current working copy as well. I hope that makes sense. Is there a way to do that?

  • High accuracy cpu timers

    - by John Robertson
    An expert in highly optimized code once told me that an important part of his strategy was the availability of extremely high performance timers on the CPU. Does anyone know what those are and how one can access them to test various code optimizations? While I am interested regardless, I also wanted to ask whether it is possible to access them from something higher than assembly (or with only a little assembly) via visual studio C++?

  • how to use oracle package to get rid of Global Temp table

    - by john
    I have a sample query like below: INSERT INTO my_gtt_1 (fname, lname) (select fname, lname from users) In my effort to getting rid of temporary tables I created a package: create or replace package fname_lname AS Type fname_lname_rec_type is record ( fname varchar(10), lname varchar(10) ); fname_lname_rec fname_lname_rec_type Type fname_lname_tbl_type is table of fname_lname_rec_type; function fname_lname_func ( v_fnam in varchar2, v_lname in varchar2 )return fname_lname_tbl_type pipelined; being new to oracle...creating this package took a long time. but now I can not figure out how to get rid of the my_gtt_1 how can i say... INSERT INTO <newly created package> (select fnma, name from users)

  • Language restrictions on iPhone partially lifted?

    - by John Smith
    Apparently Apple has changed some term in the agreement again. From http://www.appleoutsider.com/2010/06/10/hello-lua/ section 3.3.2 is now Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application. instead of the original No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). I am more interested in embedding Lua, but other people have other embeddings they want to make. I am wondering how you ask for permission, and what they mean by the terms "minor features" and "consistent" and how will Apple interpret this section? It seems to have enough loopholes to drive a real firetruck through. (BTW this is a terribly important question for me an my product.)

  • What's the advantage of an Adobe AIR app over a traditional desktop app?

    - by John
    I'm pretty familiar with using Adobe Flex & AS3, and compared with writing apps in JS/HTML I think it's very cool. However, since AIR is essentially a non-browser version of Flex with benefits like local storage, it seems to be competing as a cross-platform desktop application platform... and in that space it's much less mature than more established desktop technologies. So what's the advantage of creating a desktop application using AIR compared to something like Java (or C++ using a cross-platform GUI library like wxWidgets)? Java's equally capable of communicating with the server for instance, I'm not quite sure what AIR adds when competing head-to-head in the desktop development world?

  • Why does my git push hang after successfully pushing?

    - by John
    On a newly set up ssh git repo, whenever I push, I get normal output like this: ? git push Counting objects: 15, done. Delta compression using up to 4 threads. Compressing objects: 100% (9/9), done. Writing objects: 100% (9/9), 989 bytes, done. Total 9 (delta 7), reused 0 (delta 0) It happens very quickly, and the changes are immediately available on the server repo. But the output hangs there for about a minute, and then finishes with: To [email protected]:baz.git c8c391c..1de5e80 branch_name -> branch_name If I control-c before it finishes, everything seems to continue to be normal and healthy, locally and remotely. What is it doing while hanging? Is something configured incorrectly on the server side?

  • WebDav alternatives? Win server 2003, win 7.

    - by John
    I have an internal web page that I have an iframe with the source pointing to a webdav folder. This allows the user to drag and drop a number of files on the iframe window which a button on the main page then kicks off a server side task to process the files. I am looking for an alternative that will allow me to drag a group of files and drop them onto a target area of a web page which will then upload them to the web server. Ideally this would be in ASP.Net 2,3 or 4. Any suggestions? TIA J

  • How can I set paperclip's storage mechanism based on the current Rails environment?

    - by John Reilly
    I have a rails application that has multiple models with paperclip attachments that are all uploaded to S3. This app also has a large test suite that is run quite often. The downside with this is that a ton of files are uploaded to our S3 account on every test run, making the test suite run slowly. It also slows down development a bit, and requires you to have an internet connection in order to work on the code. Is there a reasonable way to set the paperclip storage mechanism based on the Rails environment? Ideally, our test and development environments would use the local filesystem storage, and the production environment would use S3 storage. I'd also like to extract this logic into a shared module of some kind, since we have several models that will need this behavior. I'd like to avoid a solution like this inside of every model: ### We don't want to do this in our models... if Rails.env.production? has_attached_file :image, :styles => {...}, :storage => :s3, # ...etc... else has_attached_file :image, :styles => {...}, :storage => :filesystem, # ...etc... end Any advice or suggestions would be greatly appreciated! :-)

  • Trying to understand crash log output

    - by John Smith
    I'm trying to understand debug output from a crash log. I have the following line from the crashlog: 22 FG 0x00022b94 0x1000 + 138132 I understand how to use atos on 0x00022b94 to get the source code location. What I would like to know is why the crash log helpfully splits that number into 0x1000 + 138132? I have googled and the googles failed me.

  • Kohana 3 - How do I make the Default Route pass arguments to the Controller's Action?

    - by John Himmelman
    My controller action requires a parameter, but I can't get KO3's router to pass this parameter in the Default route. This sort of thing works with other routes. Here is an example to clarify... In bootstrap.php... Route::set('default', '(<controller>(/<action>(/<the_required_param>)))') ->defaults(array( 'controller' => 'DefaultController', 'action' => 'index', 'the_required_param' => 'some_default_value', )); In controller file... class DefaultController extends Controller { public function index($the_required_param) { echo 'value: ' . $the_required_param; } }

  • R: How to separate character output in a loop?

    - by John
    I'm blanking on the best way to paste a list of strings together to go into an SQL statement... I'm having trouble with the separator bar | printing at the beginning when I don't want it to: foo = "blah" paste_all_together = NULL for (n in 1:4) { paste_together = paste(foo ,sep = "") paste_all_together = paste(paste_all_together, paste_together, sep = "|") } > paste_all_together [1] "|blah|blah|blah|blah" I just want it to print out "blah|blah|blah|blah". Do I need a nested loop, or is there a better itterator in R for doing this? Or perhaps a better way to input SQL statements?

  • Does a Distributed Version Control System really have no centralised repository?

    - by John
    It might seem a silly question, but how do you get a working drectory set up without a server to check out from? And how does a business keep a safe backed up copy of the repo? I assume then there must be a central repo... but then how exactly is it 'distributed'? I always thought of a server-client (SVN) Vs peer-2-peer (GIT) distinction, but I don't believe that can be correct unless tools like GIT are dependent on torrent-style technology?

  • How to test obtaining a list of files within a directory using RSpec?

    - by John Topley
    I'm pretty new to the world of RSpec. I'm writing a RubyGem that deals with a list of files within a specified directory and any sub-directories. Specifically, it will use Find.find and append the files to an Array for later output. I'd like to write a spec to test this behaviour but don't really know where to start in terms of faking a directory of files and stubbing Find.find etc. This is what little I have so far: it "should return a list of files within the specified directory" do end Any help much appreciated!

  • WINDOWS: Your computer hangs. You can windows + R (run dialog) but performance is so halted taskMGR

    - by John Sullivan
    The question is, what process are available to try to recover from total system instability before pulling the plug when we can do nothing but programs or batches in the path from the run dialog (windows + r key), and performance is so dead that taskMGR / procEXP / other programs with visual guis are not usable? I am not a windows expert, but ideally someone out there has written a program that does more or less stuff like this: Immediately set (or perhaps I can set from the run prompt) its priority to extremely high, evaluate performance bottlenecks. E.g. is CPU 100%? If so identify offending program(s) or problems. Attempt / log fixes, then provide crude feedback asking the user if his performance has stabilized enough to abort, wait a few seconds, if no feedback continue, etc. etc. Eventually try to do any "system cleanup" if the program decides it cannot recover and perhaps finally provide a series of beeps to the user, or what have you, to say "OK, I give up, time to pull the plug". Ideally create a log, when able. These kinds of horrible hangs are a situation where surely trying something, anything, is better than nothing -- as long as that something is intelligent -- when the alternative is ripping out the power coord. Again, I am not a windows expert, so perhaps there is a much more elegant "hands on" approach I am not aware of.
