  • Why is hibernate returning a proxy object?

    - by predhme
    I have a service method that returns an object from the database. This method is called from numerous parts of the system. However, one particular method is getting a return type of ObjectClass_$$_javassist_somenumber as the type. Which is throwing things off. I call the service method exactly the same as everywhere else, so why would hibernate return the proxy as opposed to the natural object? I know there are ways to expose the "proxied" object, but I don't feel like I should have to do that. The query is simply hibernateTemplate.find("from User u where u.username = ?", username)

  • How do I change my current directory from a python script?

    - by misterloogs
    I'm trying to implement my own version of the 'cd' command that presents the user with a list of hard-coded directories to choose from, and the user has to enter a number corresponding to an entry in the list. The program, named my_cd.py for now, should then effectively 'cd' the user to the chosen directory. Example of how this should work: /some/directory $ my_cd.py 1) ~ 2) /bin/ 3) /usr Enter menu selection, or q to quit: 2 /bin $ Currently, I'm trying to 'cd' using os.chdir('dir'). However, this doesn't work, probably because my_cd.py is kicked off in its own child process. I tried wrapping the call to my_cd.py in a sourced bash script named my_cd.sh: #! /bin/bash function my_cd() { /path/to/my_cd.py } /some/directory $ . my_cd.sh $ my_cd ... shows list of dirs, but doesn't 'cd' in the interactive shell Any ideas on how I can get this to work? Is it possible to change my interactive shell's current directory from a python script?

  • Testing whether an event has happened after a period of time in jQuery

    - by chrism
    I'm writing a script for a form-faces xforms product that is keyed off an event built into form faces. The event is called 'xforms-ready'. I have define 'startTime' as happening as soon as the document in 'ready'. What I want the script to do is warn the user that it is taking too long before the 'xforms-ready' happens, say if it's been 6 seconds since 'startTime'. I can easily do things when the 'xforms-ready' event happens using the code below: new EventListener(document.documentElement, "xforms-ready", "default", function() { var endTime = (new Date()).getTime(); } ); however the warning will want to happen before 'endTime' is defined. So I guess I want something that works like this: If 6 seconds has passed since startTime and endTime is not yet defined do X or possibly more efficiently: If 6 seconds has passed since startTime and 'xforms-ready' has not yet happened do X Can anyone suggest a way of doing this?

  • Bit conversion operations in PHP

    - by Goro
    Hello, I find myself in need of performing bit-level conversion on variables in PHP. In more detail, I have a bit stream that is read as an integer by hardware, and I need to do some operations on the bits to make it into what its actually supposed to be (a float). I have to do this a few times for different formats, and the functionality I need is Being able to select and move individual bits in a variable Being able to cast statically one type of variable to the other (ie. int to float) I know php natively supports bitwise AND, OR, etc, and shift operations, but I was wondering if: there may already be a library in php that does this sort of thing I would be better off with delegating the calculations to some other language Thanks,

  • How to network a Mac running System 7.6 with Mac OS X 10.6 or Windows Vista over Ethernet?

    - by Brian Teeter
    The title pretty much says it all. I have a Powerbook 540c that is connected to my network via Ethernet. It has no Internet tools on it at all, and its running System 7.6. I am trying to figure out a way to get it to mount a drive on either my Windows Vista workstation or my Snow Leopard Macbook. Once I do that I can get an old browser on there and get what I need off the Internet. Thus far I have not been able to get it connected. Microsoft dropped Appletalk support in XP and despite enabling Appletalk on my Macbook, the powerbook cannot see it in the Chooser. Any ideas?

  • Creating a PHP call home "time bomb" to protect my interests

    - by RC
    Hi everyone, I produced a PHP web app for a client some months back that is hosted on their own server. I have still not been paid for this work, and they are giving me the runaround. It turns out that I still have remote admin access to their server, so I can make code changes. What I was thinking of doing was to move the core kernel off-site onto one of my own servers, and program in some kind of callback or include that gets the kernel (critical functions) from my server. Give it two weeks or so for their backups to catch this change, and then pull the plug and exercise leverage. If I do this, they will pay immediately, because the site is a critical one for a very large and influential client of theirs. What is the most effective and easiest way of doing this? What code do I use? Thanks for any pointers.

  • Why are the default UI controls in my iPhone app blurred?

    - by Tom H
    Why would the default iPhone interface elements, specifically the UISwitch (unmodified) and a UISegmentedControl appear slightly blurred? I have not changed them or called any private APIs. This blurring occurs when I run it both in the simulator and when I load it on my iPod Touch, so I don't think it's a one off drawing glitch. These elements were created via some code (initWithFrame:) not in interface builder. Here is a screenshot of the blurring in the simulator: http://drp.ly/14rS6a It looks similar on the actual device. Thanks for your help

  • CI Build status output alternatives

    - by Brett Rigby
    We currently use Cradiator to display the status of our continuous integration (CI) builds from CruseControl.net, on a 42" Samsung television on display high-up in our IT department. Cradiator is a great starting place, but we're getting to the point whereby we're having lots of projects on there and it's starting to get a bit 'full'. What I'd like to know is, what do you use to display your build statuses? Custom software? Off the shelf stuff? etc. Alternatively, I'm looking for ideas on how we improve on Cradiator.

  • Advice for building a browser-based audio mixer up to 32 tracks

    - by Jonathan P.
    As a personal hobby I am looking to build an online audio mixer where I can upload individual instrument tracks, control individual volumes of each track, and export the mixed down version. I've been trying (and have come pretty close) with javascript. I really would like to stay away from flash if possible, but I'm really looking for suggestions for technologies to try. If anyone has any suggestions on languages that are good at stuff like this or libraries that I am missing, please let me know! I have a test environment that I have been using: http://driverstestpractice.com/sandbox Currently all tracks on the site are set to the click track in order to test the track sync (which as you can tell is a little off)! Thanks!

  • Firefox HTML5 video playback inconsistancy

    - by Daniel Redwood
    Hey all, I've got an HTML5 video on a page. When tested locally, Chrome, Safari, and Opera work beautifully. Firefox plays it, but doesn't loop as efficiently as the others. The real problem is when it's tested off a server. Firefox doesn't play the video, but recognizes there is one there. I was wondering if all that open ended three-different-ways syntax can be swung in Firefox's favor. Thanks! HTML: <video id="vid_home" width="780" height="520" autoplay="autoplay" loop="loop"> <source src="Video/fernando.ogv" type="video/ogg" /> <source src="Video/fernando.m4v" type="video/mp4" /> Your browser does not support this videos playback. </video>

  • Find a part of UNC path and put in a variable?

    - by Refracted Paladin
    I am trying to peel off the last part of a unc path that is being passed and put it in a variable to use in a method further down the line. Example path would be -- \\ourfileserver\remoteuploads\countyfoldername\personfoldername How do I peel just the countyfoldername out of that? I had thought to try var th = e.FullPath.LastIndexOf('\\'); var whichFolder = folderPath.Substring(th); but that is an escape character and it doesn't like @ either. Is this even the right direction?

  • Should I aim for fewer HTTP requests or more cacheable CSS files?

    - by Jonathan Hanson
    We're being told that fewer HTTP requests per page load is a Good Thing. The extreme form of that for CSS would be to have a single, unique CSS file per page, with any shared site-wide styles duplicated in each file. But there's a trade off there. If you have separate shared global CSS files, they can be cached once when the front page is loaded and then re-used on multiple pages, thereby reducing the necessary size of the page-specific CSS files. So which is better in real-world practice? Shorter CSS files through multiple discrete CSS files that are cacheable, or fewer HTTP requests through fewer-but-larger CSS files?

  • How to create a 'Hot or Not' website

    - by Casper
    Hi guys, I'd like to create a website with similar concept as 'Hot or Not' where users need to sign up to the website and then upload photos. Each photo can be given a description and some additional fields. Other users may comment and rate the photo entries. On top of that, users may favourite/bookmark (and remove) any photo entries and they're accessible via their profile page That's generally how the website will be. Can't decide on a CMS to use Somehow I'm at a crossroad here. I've done some research and found that Joomla has an extension that is able to pull this website off but the thing is I'm not that comfortable with using Joomla. I work with WordPress most of the time, but I can't seem to figure out how would I build this website with WordPress. Would using BuddyPress make it work? Would hiring a plugin developer to customize some plugins work? What do you guys think?

  • The 100% width HTML element problem

    - by Xeoncross
    When assigning some HTML elements (like a form input) 100% width - you can no longer apply any additional styles that might effect the width. Things like border or padding will cause the element to exceed 100%. This results in awkward elements that may be outside of their parent elements. Since CSS doesn't support width: 100% - 2px; The only way I know around this is to use an absolute pixel width (width: 98px) or chop the element off at 100% which is not really an option. <div style="overflow:hidden;"> <input style="width:100%; border: 1px solid #000;" /> </div> Are they're any other ways around this?

  • Best indexing strategy for several varchar columns in Postgres

    - by Corey
    I have a table with 10 columns that need to be searchable (the table itself has about 20 columns). So the user will enter query criteria for at least one of the columns but possibly all ten. All non-empty criteria is then put into an AND condition Suppose the user provided non-empty criteria for column1 and column4 and column8 the query would be: select * from the_table where column1 like '%column1_query%' and column4 like '%column4_query%' and column8 like '%column8_query%' So my question is: am I better off creating 1 index with 10 columns? 10 indexes with 1 column each? Or do I need to find out what sets of columns are queried together frequently and create indexes for them (an index on cols 1,4 and 8 in the case above). If my understanding is correct a single index of 10 columns would only work effectively if all 10 columns are in the condition. Open to any suggestions here, additionally the rowcount of the table is only expected to be around 20-30K rows but I want to make sure any and all searches on the table are fast. Thanks!

  • What to do when you are a programmer and have a cold?

    - by Zak
    If you have a cold that isn't too bad, does it make sense to still go into the office and get some coding done? Assume a private office, no meetings for the day, and you have some documentation and coding tasks that need to get done. Also assume that you operate on a PTO system, where all days off are "vacation" or PTO. To clarify, should one just not code at all when under the weather? That's what I'm getting at. Will you just kick yourself in your own rear when you go back to deal with code you wrote when you are sick? What is the error defect rate of sick vs non-sick programming hours?

  • Insert objects into a collection with LINQ based on a property of the existing objects in the collection

    - by DavidS
    Hi, I've got a collection of object which contains data as follows: FromTime Duration 2010-12-28 24.0000 2010-12-29 24.0000 2010-12-30 24.0000 2010-12-31 22.0000 2011-01-02 1.9167 2011-01-03 24.0000 2011-01-04 24.0000 2011-01-05 24.0000 2011-01-06 24.0000 2011-01-07 22.0000 2011-01-09 1.9167 2011-01-10 24.0000 In the "FromTime" column, there are data "gaps" i.e. 2011-01-01 and 2011-01-08 are "missing". So what I'd like to do is to loop through a range of dates (in this instance 2010-12-28 to 2011-01-10) and "fill in" the "missing" data with a duration of 0. As I've just started with LINQ, I feel that it should be "fairly" easy but I can't quite get it right. I'm reading the book "LINQ in Action" but feel that I'm still quite a way off before I can resolve this particular issue. So any help would be much appreciated. David

  • Closing a window when it's "no longer needed".

    - by Mason Blier
    This is kind of a hard question to describe, and I've searched for about an hour now to no avail. Essentially, picture a small 'flyout' window like the Windows 7 Wireless Control or the Volume Slider from the system tray(notification area). When you click on the icon, the application pops up with focus, and if you click off of it, the window destroys itself. I thought it woudl be easily solved by simply having my window destroy it self when it loses focus (I've been listening for WM_KILLFOCUS), but the problem is, if the icon is clicked, my window does not always get focus. Since this isn't the case, if the user clicks my icon, and then clicks away because it was a mistake (on the desktop say), then how can I set my app to close? I've tried messing with SPY++ but checking the volume control / wireless control apps are proving difficult as they disappear when I try to get their window/process handles. Thanks!

  • Execute a dll function in ASP.Net Bin not working, II7.

    - by Wayne Lo
    I am developing a remote control application where a client (aspx page in a browser) can request a server to "launch a notepad" (for testing purpose, for real life, turning off a light bulb, etc). So I created a dll with a simple function for launching the notepad (on the server side) and dropped this dll in the root bin folder. It worked fine when the aspx page is running under ASP.NET development server (launched from Visual Studio). But when I tested the same aspx page under a FireFox browser, it did not work (launch the notepad) even though it did call for the same function (I stepped through in debugger). Is this a permission issue? How do I set this up in IIS manager, or even better in web.config? Please help.

  • How much trust can I put behind a computer system? How can I measure trust?

    - by danmine
    How much trust can I put in a standard computer running windows? To what certainty can I be sure it will run my code the way I wrote it? How can I be sure that if I declare something like "int j = 5;", j will alway be 5? Is there a way to measure trust in a standard x86 computer system? What kind of protections are there to make sure that j = 5? I'm thinking about critical systems where nothing can be off even by one bit and everything must run exactly the way it was written to run.

  • Rails - Preventing users from contributing to website when there score is too low - callback / obser

    - by adam
    A User can add a Sentence directly on my website, via twitter or email. To add a sentence they must have a minimum score. If they don't have the minimum score they cant post the sentence and a warning message is either flashed on the website, sent back to them via twitter or email. So I'm wondering how best to code this check. Im thinking a sentence observer. So far my thoughts are in before_create score_sufficient() - score ok = save - score too low = do not save In the case of too low i need to return some flag so that the calling code can then fire off teh relevant warning. What type of flag should I return? False is too ambiguous as that could refer to validation. I could raise an exception but that doesn't sound right or I could return a symbol? Is this even the right approach? What's the best way to code this?

  • Float as DateTime

    - by lp1
    SQL Server 2008 I almost have, I think, what I'm looking to do. I'm just trying to fine tune the result. I have a table that stores timestamps of all transactions that occur on the system. I'm writing a query to give an average transaction time. This is what I have so far: With TransTime AS ( select endtime-starttime AS Totaltime from transactiontime where starttime > '2010-05-12' and endtime < '2010-05-13') Select CAST(AVG(CAST(TotalTime As Float))As Datetime) from TransTime I'm getting the following result: 1900-01-01 00:00:00.007 I can't figure out how to strip the date off and just display the time, 00:00:00:007. Any help would be appreciated. Thank you.

  • Should I design the application or model (database) first?

    - by YonahW
    I am getting ready to start building a new web project in my spare time to bring to fruition an idea that has been bouncing around my head for a while. I have never gotten down whether I am better off first building the model and then the consuming application or the other way around. What are the best practices? What would you build first and why? I imagine that in general the application should generally drive the model, however the application like many websites really doesn't do much without the model. For some reason I find it easier at times to think in terms of the model since the application is really just actions on the model. Is this a poor way of thinking about things? What advantages/disadvantages does each option have?
