  • Django "Error: cannot import name escape" on windows

    - by Sam
    I cannot run the dev server because of this error ("Error: cannot import name escape"). I assume its because of modifications I've done to the project, but i have no idea how to find where the error is originating from to fix it. I don't import anything called escape anywhere. Update Using django-admin.py rather than the projects manage.py, don't know why... Update 2 Now manage.py is working. This may be because I had a file called email.py which was trying to import email.mime.text (ie trying to import itself) renaming to sendemail.py solved this problem.

  • How can I speed up the "finally get it" process?

    - by Earlz
    Hello, I am a hobby programmer and began when I was about 13. I'm currently going to college(freshman) for my computer science degree(which means, I'm still in the stuff I already know such as for loops). I've been programming professionally for a start up for about 9 months or so now. I have a serious problem though. I think that almost all of the code I write is perfect. Now I remember reading an article somewhere where there is like 3 stages of learning programming You don't know anything and you know you don't know anything. You don't know anything but you think you do. You finally get and accept that you don't know anything. (if someone finds that article tell me and I'll give a link) So right now, I'm at stage 2. How can I get to stage 3 quicker? The more and more of some people's code I read I think "this is complete rubbish, I would've done it like..." and I really dislike how I think that way. (and this fairly recently began happening, like over the past year)

  • Practical ways around the GPL?

    - by Daniel
    My company makes an extremely specialized piece of software which costs a lot of money for those few who need it. On our current release we have no choice but to use a few libraries which are released only under the GPL. Releasing the code is not an option and it would take months, if not years to implement the functionality the libraries provide. What do companies do in this situation? Are there practical and legal ways around the GPL?

  • Soften a colour border, maybe with a gradient, programmatically.

    - by ProfK
    I have a narrow header in corporate colour, bright red, with the content below on a just-off-white background. Ive tried softening the long line where these colours meet using border type divs with intermediate backgrounds, but I think I need the original type curved gradient 'area transitions'. I could copy the 1024px wide, and too narrow (vertically), header gif from their web site, and chop it up for eight border images, but that seems clumsy, and I'm looking for something I can apply anywhere, without needing images. I am able to do round borders in the x-y plane, but I'm curious as to how I can apply a gradient to any chosen colour transition. The extra divs I'm using as border elements above and below '#top-section' arose when I was toying with making many divs for one bordered element. This seemed the ultimate in border manipulation, sans code, but very tedious to spec in CSS and lay out a new border for each bordered element. <div id="topsection"> <div style="float: right; width: 300px; padding-right: 5px;"> <div style="font-size: small; text-align: right;"> Provantage Media Management System</div> <div style="font-size: x-small; text-align: right;"> <asp:LoginStatus ID="loginStatus" runat="server" LoginText="Log in" LogoutText="Log out" /> </div> </div> <span style="padding-left: 15px;">Main Menu</span><span id="content-title"> <asp:ContentPlaceHolder ID="titlePlaceHolder" runat="server"> </asp:ContentPlaceHolder> </span> <div style="background-color: white; height: 2px;"> </div> <div style="background-color: white; height: 3px;"></div> And the CSS: #topsection { background-color: #EB2728; color: white; height: 35px; font-size: large; font-weight: bold; }

  • whJavaScript: how to create a JS event that requires 2 seperate JS files to be loaded first while d

    - by Teddyk
    I want to perform asynchronous JavaScript downloads of two files that have dependencies attached to them. function addScript(url) { var script = document.createElement('script'); script.src = url; document.getElementsByTagName('head')[0].appendChild(script); } addScript('http://google.com/gmaps.js'); addScript('http://jquery.com/jquery.js'); function requiresJQuery() { ... } function requiresGmaps() { ... } function requiresBothJQueryGmaps() { ... } // do some work that has no dependencies on either JQuery or Google maps ... // now call a function that requires Gmaps to be loaded if (GmapsIsLoaded) { requiresGmaps(); } // then do something that requires both JQuery & Gmaps (or wait until they are loaded) if (JQueryAndGmapsIsLoaded) { requiresBothJQueryGmaps(); } Question: How can I create an event to indicate when: JQuery is loaded? Google Maps is loaded JQuery & Google Maps are both loaded?

  • Keeping the application state - deploy/install apk

    - by Buffalo
    I'm trying to have my application minimized when paused and then when it's resumed, it should be restored to its previous state, not recreated. This works perfectly when deploying the application on a device/emulator from Eclipse. The problem occurs when I get the apk (either from bin\ or from Project - Android tools - Export signed application package) and install it on a device with a file browser (Astro): the application is destroyed when paused and then recreated. I can call moveTaskToBack(true); in my activity, yet it will still be recreated when launching it. All the discussions around this are based on achieving the opposite: closing the application when minimizing it. Is there any way of achieving what I want?

  • JavaScript: How can I delay running some JS code until my JS file downloaded?

  • 2D Platformer Collision Problems With Both Axes

    - by AusGat
    I'm working on a little 2D platformer/fighting game with C++ and SDL, and I'm having quite a bit of trouble with the collision detection. The levels are made up of an array of tiles, and I use a for loop to go through each one (I know it may not be the best way to do it, and I may need help with that too). For each side of the character, I move it one pixel in that direction and check for a collision (I also check to see if the character is moving in that direction). If there is a collision, I set the velocity to 0 and move the player to the edge of the tile. My problem is that if I check for horizontal collisions first, and the player moves vertically at more than one pixel per frame, it handles the horizontal collision and moves the character to the side of the tile even if the tile is below (or above) the character. If I handle vertical collision first, it does the same, except it does it for the horizontal axis. How can I handle collisions on both axes without having those problems? Is there any better way to handle collision than how I'm doing it?

  • validates_uniqueness_of...limiting scope - How do I restrict someone from creating a certain number

    - by bgadoci
    I have the following code: class Like < ActiveRecord::Base belongs_to :site validates_uniqueness_of :ip_address, :scope => [:site_id] end Which limits a person from "liking" a site more than one time based on a remote ip request. Essentially when someone "likes" a site, a record is created in the Likes table and I use a hidden field to request and pass their ip address to the :ip_address column in the like table. With the above code I am limiting the user to one "like" per their ip address. I would like to limit this to a certain number for instance 10. My initial thought was do something like this: validates_uniqueness_of :ip_address, :scope => [:site_id, :limit => 10] But that doesn't seem to work. Is there a simple syntax here that will allow me to do such a thing?

  • Black outline around map polygons (IE)

    This only happens in some IE's. Here: http://animactions.ca/Animactions/volet_entreprise.php You may notice that when you click and drag on one of the circles, you will get something similar to this: http://img534.imageshack.us/img534/7578/errorra.png I cannot figure it out.

  • Is it possible to redirect non-HTML files with HTTP? And chaining redirects?

    - by Earlz
    Hello, I have been thinking about a neat way of load balancing and one thing that would be required is to be capable of loading an image on an HTML page from multiple locations without rewriting the URL(on each load) So what I need to be able to do is have one URL which is the "static" URL. Such as http://example.com/myimage.png The image is not actually contained in example.com though. So example.com does a either a 302 or 301 or 307 HTTP response to cause a redirect to 2.example.com. How do browsers handle this with images like in this situation? Also, how do browsers handle multiple redirections for instance if 2.example.com also didn't contain it and it went to 3.example.com ? (Note, I am asking this because I've never seen a 301 redirect on anything but an HTML page) Also, which status code would be best to use. 301 means "moved permanently" which this "move" isn't permanent so I don't want it cached. Should I use 307? Is that supported by search engines and modern browsers?

  • If you could unlearn everything you know, and start again

    - by Rob Conery
    I'm giving a presentation at NDC 2010 and in one of the talks I'm going to focus on education and its power over your career (and you personally). There are people who mercilessly educate themselves, and there are others who are a bit ho-hum about it, feeling a bit of apathy. If you remove all of the risk associated surrounding a "refocus" of your career - what choices would you make? What things would you learn and what would you do with it? Think of it as a reroll, Ground Hog day, starting over from scratch today. What platform and language choices would you make and why? Most important to me are those who are completely happy where they are - would love to hear more about what it is that keeps you where you're at. Please do let me know what platform and tools you work with - it would help tremendously! Thanks in advance.

    HTML: <a href="#" rel="tooltip">Open Tooltip</a> <div id="tooltip">Tooltip Content</div> I checked out some tooltip plugins but my requirement is a really basic tooltip that shows a hidden div on hover. All plugins either have too many advanced options that I don't require and have already styled tooltips that might be difficult to modify. I'd appreciate any help. Thanks.

  • What are the advantages and disadvantages of a web site that contains a single page ?

    - by Misha Moroshko
    I would like to code a little web site that will contain several sections like "Home", "Gallery", "Contact Us", "FAQs", and so on. I thought to do this in one HTML by putting each section in a div and show only one div per time (using Javascript / jQuery), based on the chosen menu button. Alternatively, I could create a separate HTML page per section, and link these pages to the menu buttons. What are the advantages and disadvantages of these two methods ?

  • Do you take the pain of learning it or use an out of the box solution?

    - by Mantorok
    Hi all What I'm getting at here is being presented with a control or framework that does 95% of what you want but has its shortcomings when opposed to learning how to do it yourself. To give a good example (ASP.Net) UpdatePanel vs DIY JS/JSON. The UpdatePanel gives you AJAX instantly without doing anything additional, however I've come to learn that its shortcomings are mainly that it's a bit of a hack and performs badly on busy pages and I've found myself having to scrap UpdatePanels in favour of rolling my own JS, and I've now made it a habit to fully investigate any shortcomings in out-of-the-box solutions, as I've been stung by this experience. So I guess what I'm asking is: Is it better to find out how to DIY or is it considered a better approach to try the available solution and risk going a full circle? Obviously I've only targetted a single control, but it is a very attractive control to people learning AJAX - I'm sure there are others out there. Sorry if dupliate. Thanks

  • Like posts over Facebook graph api

    - by Sima
    HI! I have little problem with facebook PHP SDK..I want to like a post, or something else via facebook PHP SDK..I am doing this code, I think it should be right, but  apparently it's not working..The given error code is, the PHP SDK dont know this kind of POST request(the generated link is definitely alright). What I have seen on Facebook Developers page is about the same..There is an example of Curl command, and I the PHP SDK is doing this requests over Curl (propably). $this->getFacebook()->api("/"+$id+"/likes", 'post'); This is what I am using in my code and it's not working(Facebook API Exception unsupported post request). Maybe, I have bad syntax in my code, but, for example, when I want to post a status to my Profile, it's working..Another cause which confused me, was when I tried to fetch these data over Graph api(on the documentation page is written, I should use address like graph.facebook.com/POST_ID/likes)... You can comment on or like a post by posting to https://graph.facebook.com/POST_ID/comments and https://graph.facebook.com/POST_ID/likes,respectively: curl -F 'access_token=...' \ https://graph.facebook.com/313449204401/likes <=this is from facebook documentation And all these requests or commands(liking ones, comments have I not yet tried) are putting me back a JSON array which contents any already existing likes, but my like is nowhere. Does anyone know what to do?How to like a post from PHP..There are other SKDs like FQL, but I haven't any knowlegde with it, so I like rather to use the standard PHP SDK(but if is there some possibility how to call for example FQL from PHP SDK, here I am:)) Please help..
