  • Partials vs for loop — best practices

    - by Mike
    In coding up your view templates you can render a partial and pass an array of objects to be rendered once per object. OR you can use a For blank in @blank loop. How do you decide when to do which? It seems that if you use a partial for every iterable object you will end up having to modify tons of separate files to make changes to potentially one view. With the loops you can see everything right there in one file.

  • Image improvment methods for OCR Engine

    - by Amir
    Hello every one, We are working on a software that uses OPENOCR engine to do some OCR on given images, given we are using .NET framework , i was wondering if anyone knows about any good possible filters or sharpening methods that can be applied to the image prior to sending it to OCR engine. I have found for example a grayscaled image is much easier for OCR engine to read than a color images. are there any other techniques or image filttering that you guys know of , that can decrease the error margin by OCR engine ? Thanks a million -Amir

  • Git already up to date unless I reset

    - by Chris
    I have a cloned repo I use for the live site and I have it pull from a bare repo. For some reason every time I execute "git pull" I get the already up to date message. But it's not up to date and not updated. If I do a git reset --hard HEAD^ and then git pull again, the changes come in. What's the problem here and how do I fix it so that git pull will pull and merge changes in without needing a hard reset?

    - by nishant
    I need a function in global.asax file which gets called only once when user enter a page url. application_beginrequest gets called 50-60 times in a single page( as to render a page several requests go to server.) i though of a solution - I can write my fucntion in global.asax and call it on page load of other pages but in that solution I need to call it in every page. I would prefer something which is to be done only in global.asax

  • How do I use the subversion revision of a css file to prevent browser cache

    - by Clayton
    StackOverflow implements it like this: <link rel="stylesheet" href="http://sstatic.net/so/all.css?v=4542"> Every time the referenced files change, the href attribute of the link tag is updated in the HTML code, thus supporting caching and updated referenced files. My question - how do you retrieve the subversion version of that css file to include in the link? Subversion keywords only tell you the revision of the file you are currently in. I'm working with PHP/CodeIgniter + jQuery.

  • Lazy load pages in UIScrollView

    - by jean
    I have a UIScrollView that contains large images and am using paging to scroll between images. In order to save memory, I am loading only one image before and after the currently visible one and loading/releasing new images after a scroll has completed. The problem occurs when one scrolls quickly and scrollViewDidEndDecelerating is not called. How can I detect continuous scrolling? I could check item location on every scrollViewDidScroll but this seems a bit heavy...

  • Removing Design Outlining

    - by Kevin
    Is there a way to remove the outlining in Visual Studio in the design page of a form? If it is possible, it would save me some time so that I would not have to keep compiling and running the program every time I wanted to see if I put my form together correctly without any caps between images, etc. For example, something like this. I want to remove the lines that surround each image (yes, those are separate images put together).

  • Turing-Complete language possibilities?

    - by I can't tell you my name.
    In every Turing-Complete language, is it possible to create a working Compiler for itself which first runs on an interpreter written in some other language and then compiles it's own source code? (Bootstrapping) Standards-Compilant C++ compiler which outputs binaries for, e.g.: Windows? Regex Parser and Evaluater? World of Warcraft clone? (Assuming the language gets the necessary API bindings as, for example, OpenGL and the WoW source code is available) (Everything here theoretical) Let's take Brainf*ck as an example language.

  • MySQL table partitioning qn:

    - by JVXR
    I have a table (innodb) that will have billions of records eventually. Every 2nd week I expect ~ 500K records to get dropped into the table. I would want to partition this table based on the date on which the data is imported - luckily this is a field in the table that is of the format yyyy-mm-dd - Is it possible to partition it based on this date column ? I tried looking at the 18th chapter of mysql docs but couldn't figure out if this is possible. -tia

  • The speed of Ruby and Java.

    - by Simon
    In every benchmark that I found on the web it seems that Ruby is slow, much slower than Java. The Ruby folks just state that it doesn't matter. Could you give me any example that the speed of Ruby on Rails (and the Ruby itself) really doesn't matter?

  • What are the best Perl Introductions and references?

    - by Kieveli
    I've been programming for 15+ years, and I've done perl programming 3 times in the past. Every time I come back to it, I remember nothing of the language. It's very bizarre. Now it's time to hit perl again, and I'm wondering what the best Intro / Reference / Best Practice sites are that people use. Which Perl Intro / Reference site do you recommend?

What is happening? Has Visual Studio GONE CRAZY?!?!?!?!?!?!?!

  • Django Admin Actions missing

    - by Andrew C
    One of my Django sites is missing the Django Admin Action bar shown here: http://docs.djangoproject.com/en/dev/ref/contrib/admin/actions/#ref-contrib-admin-actions There is no checkbox next to each row and no Action select box near the top of the page. This is happening on every model. I have several sites running Django 1.1, and they all show the Admin Actions, so it feels like a local configuration issue. Anyone seen this before?

  • Asp.net hosting equivalent of Dreamhost (pricing, features and support)

    - by Cherian
    Disclaimer: I have browsed http://stackoverflow.com/questions/tagged/asp.net+hosting and didn’t find anything quite similar in value to Dreamhost. One of the biggest impediments IMHO for developing web applications on asp.net is the cost of deployment. I am not talking about building sites like Stackoverflow.com or plentyoffish.com. This is about sites that are bigger than brochureware and smaller than ones that require dedicated servers. Let me give you an example. xmec.org is an asp.net site I maintain for my college alumni. On an average it’s slated to hit around 1000-1100 views per day. At present it’s hosted on godaddy. The service is so damn pathetic; I am using it only because of the lack of options. The site doesn’t scale (no, it’s not the code) and the web control panels are extremely slow. The money I pay doesn’t justify the service or the performance. Every deployment push is a visit to the infuriating web control panel to set the permissions and the root directories. Had I developed it in python, this would have been deployed on Dreamhost.com with $10/year hosting fees (they have offers running all throughout) 50 GB space 5 MySQL Databases Shell / FTP Users POP / SMTP Access Unlimited Domains hosting Unlimited Sub domains hosting Unlimited Domains Forwarded/Mirrored Custom DNS (These are the only ones I could think of. More at the feature page) With a dream host shell, I even have a svn checked-out version of wordpress for my blog. Now, that’s control! To my question: Is there any asp.net (preferably .net 3.5. Dreamhost keeps on updating versions every fortnight) hosting company providing remotely similar feature-sets and pricing like Dreamhost. My requirements are: Less than $15-25/ year Typical WISP minus PHP .net 3.5 SP1 Full Trust mode(I can live with medium trust, if not for the IL emitting libraries) Isolated Application Pool 5 – 10 MySQL db’s Unlimited domain hosting MsSql 2005 or 2008 FTP support At Least 5 GB space SMTP IIS 7 Log files Accessibility Moderately good control panel Scripting, shell support Nominal bandwidth Another case in point: Recently I’ve been contemplating building a tool-website to find duplicates and weird characters in my Google contacts and fix them. With asp.net, the best part is that I can do this with LINQ to XML in less than 100 lines of code. What’s bad is the hosting part. I don’t think I stand to make any money out of this and therefore can’t afford to host it on GoGrid or DiscountAsp.net. Godaddy is not an option either. If I do this in python, I can push to this my existing $10 Dreamhost account with another domain pointed. No extra cost. Svn exported with scripts (capability) to change the connection string! Looking at the problem holistically, I think I represent a large breed of programmers playing it cheap and experimenting different things on a regular basis, one of which will become the next twitter/digg.
