• Suggest Sphinx index scheme

  - by htf

  Hi. In a MySQL database I have documents of different type: some have text content, meta keys, descriptions, others have code, SKU number, size and brand name and so on. The problem is, I have to search something in all of these documents and then display a single page, where the results will be grouped by the document type, such as help page, blog post, item... It's not clear for me how to implement the Sphinx index: I want to have a single index to speed up queries, but since different docs have different structure - how can I group them? I was thinking about just concatenating them, but it just doesn't feel right.

• Join using combined conditions on one join table

  - by Nathan Wienert

  I have join a table joining songs to genres. The table has a 'source' column that's used to identify where the genre was found. Genres are found from blogs, artists, tags, and posts. So, songs | song_genre | genres id | song_id, source, genre_id | id What I want to build is a song SELECT query that works something like this, given I already have a genre_id: IF exists song_genre with source='artist' AND a song_genre with source='blog' OR exists song_genre with source='artist' AND a song_genre with source='post' OR exists song_genre with source='tag' I'm was going to do it by doing a bunch of joins, but am sure I'm not doing it very well. Using Postgres 9.1.

• Scrolling through list element causes text elements to scroll as well

  - by DMK

  I'm using a list element with variableRowHeight and word-wrap set to true like in the example below: http://blog.flexexamples.com/2007/10/27/creating-multi-line-list-rows-with-variable-row-heights/ When I scroll through the list with a mouse scrollwheel the text in the listItems also scroll. I know that this is to do with the height of the textField... but I am unsure how to best resolve this issue. Any thoughts are appreciated! The issue that I am experiencing also occurs in the example above.

• PHP OOP: Unique method per argument type?

  - by sunwukung

  I'm writing a little homebrew ORM (academic interest). I'm trying to adhere to the TDD concept as a training exercise, and as part of that exercise I'm writing documentation for the API as I develop the class. Case in point - I'm working on a classic "getCollection" type mapper class. I want it to be able to retrieve collections of asset X (let's say blog posts) for a specific user, and also collections based on an arbitrary array of numeric values. So - you might have a method like any one of these $User = $UserMapper->load(1); $ArticleCollection = $ArticleMapper->getCollection(range(10,20)); $ArticleCollection = $ArticleMapper->getCollection($User); $ArticleCollection = $ArticleMapper->getCollection($User->getId()); So, in writing the documentation for the getCollection method - I want to declare the @param variable in the Docblock. Is it better to have a unique method for each argument type, or is it acceptable to have a method that delegates to the correct internal method/class based on argument type?

• First html5 website, see any mistakes?

  - by noxxten

  http://dl.dropbox.com/u/921159/designgoods/index.html I've made my first html5 website by converting another blog theme I had. It's actually a pretty sloppy job since its a learning experience and all. I know some files (like favicons and some scripts) are useless/not linked, but seeing as this is a test I won't bother creating them. But do you see any mistakes I made? Any 'better practices' to point out? :) Any C&C is very welcome and appreciated!

• What is a good cms that is postgres compatible, open source and either php or python based?

  - by hackg

  Php or python Use and connect to our existing postgres databases open source / or very low license fees Common features of cms, with admin tools to help manage / moderate community have a large member base on very basic site where members provide us contact info and info about their professional characteristics. About to expand to build new community site (to migrate our member base to) where the users will be able to msg each other, post to forums, blog, share private group discussions, and members will be sent inivitations to earn compensation for their expertise. Profile pages, job postings, and video chat would be plus. Already have a team of admins savvy with web apps to help manage it but our developer resources are limited (3-4 programmers) and looking to save time in development as opposed to building our new site from scratch.

• Mysql search design

  - by neil

  I'm designing a mysql database, and i'd like some input on an efficient way to store blog/article data for searching. Right now, I've made a separate column that stores the content to be searched - no duplicate words, no words shorter than four letters, and no words that are too common. So, essentially, it's a list of keywords from the original article. Also searched would be a list of tags, and the title field. I'm not quite sure how mysql indexes fulltext columns, so would storing the data like that be ineffective, or redundant somehow? A lot of the articles are on the same topic, so would the score be hurt by so many of the rows having similar keywords? Also, for this project, solutions like sphinx, lucene or google custom seach can't be used -- only php & mysql. Thanks!

• Python Continue Loop

  - by Rob B.

  I am using the following code from this tutorial (http://jeriwieringa.com/blog/2012/11/04/beautiful-soup-tutorial-part-1/). from bs4 import BeautifulSoup soup = BeautifulSoup (open("43rd-congress.html")) final_link = soup.p.a final_link.decompose() trs = soup.find_all('tr') for tr in trs: for link in tr.find_all('a'): fulllink = link.get ('href') print fulllink #print in terminal to verify results tds = tr.find_all("td") try: #we are using "try" because the table is not well formatted. This allows the program to continue after encountering an error. names = str(tds[0].get_text()) # This structure isolate the item by its column in the table and converts it into a string. years = str(tds[1].get_text()) positions = str(tds[2].get_text()) parties = str(tds[3].get_text()) states = str(tds[4].get_text()) congress = tds[5].get_text() except: print "bad tr string" continue #This tells the computer to move on to the next item after it encounters an error print names, years, positions, parties, states, congress However, I get an error saying that 'continue' is not properly in the loop on line 27. I am using notepad++ and windows powershell. How do I make this code work?

• Cakephp: Access data in add function

  I'm using the CakePHP blog example: function add() { if (!empty($this->data)) { if ($this->Post->saveAll($this->data)) { $this->Session->setFlash('Your post has been saved.'); $this->redirect(array('action' => 'index')); } }} I want to modify it in a way that the user is redirected to the post after adding it: But this doesn't work: $this->redirect(array('action' => 'view', $this->Post->id))); What is the correct way to read the model's data after creation?

• To change checkbox text or to not change?

  - by Axarydax

  Hi, I'm having an argument with a co-worker, and I'm trying to convince him that it's a bad idea to change checkbox text (label) according to the checkbox state. For example, we have a combobox that automatically picks selected value (and is disabled) when checkbox next to it is checked and is enabled when checkbox is cleared. His idea is to show Autoselect when checkbox is checked and Manual select when it's cleared. I'm sure that this will confuse the user as users tend to think that checking a checkbox next to a verb will make it true, only to find that the label has changed to something else. What is your opinion on this matter? P.S. I remember reading about changing checkbox text somewhere, in a book or blog article, but can't remember where. It would be great to have this in writing :-)

• Propor usage of double and single quotes?

  - by Phox

  I'm talking about the performance increase here. From all I know you can echo variables in double quotes ("), like so: <?php echo "You are $yourAge years old"; ?> But single quotes will just return You are $yourAge years old. But what about performance differences? I've always gone by the rule that single quotes are faster because the PHP interpreter doesn't have to search through the string for variables. But I'm seeing more and more blog and forum posts on the web saying differently. Does anyone actually have any information on this subject? Perhaps benchmark tests or something? Cheers.

• How much more productive is an extra monitor?

  - by Sir Graystar

  I am mulling over whether to buy a new monitor, to go along side my current setup of two 24 (ish) inch monitors. What I want to know is whether this is worth the money (probably around £200)? I think most of us will agree that two monitors is much more productive than one when programming and developing (Jeff Atwood has said this many times on his blog, and I imagine that most of you are fans of his), but is three much more productive than two? What I'm worried about is that I will have so much space that one monitor will be used for things that are not related to the task (music, facebook etc.) and it will actually make me less productive.

• How do a search a table for similar records and displaying count - Ruby on Rails

  - by bgadoci

  I have created a table in my Ruby on Rails application that I am building called Tags. It is a blog application so I allow the user to associate tags with a post and do this through a :posts, :has_many = tags and Tag belongs_to :post association. Now that I have my Tags table I am trying to see how I would render the view such that it displays the tag and tag count. (it should be noted that I am trying to render this in the /views/posts/index.html.erb file). For instance, if there are 10 entries in the Tag table for tag_name Sports. How can I display Sports (10) in the view. I am not looking to do this for a specific tag but rather, somehow search the table, combine like tags and display a list of all tags with counts next to them. (I really want these to be a link to a list of posts that contain that tag but I learned early on only to ask one question at a time). Hope that makes sense.

• Will Visual Studio 2010 support HTML 5?

  - by Chris

  Since Visual Studio 2010 is slated for release in March of 2010 and HTML 5 is now starting to be used even more widely, I would like to know if Visual Studio will ship with HTML 5 templates, standard controls and support for the more common markup? A definition for support of HTML 5 would be that any new version of Visual Studio should have similar support for code-completion, validation and markup that is currently supported for HTML 4.01 and XHTML 1.0 and 1.1. Update From the Visual Web Develolper Team Blog: HTML 5 intellisense and validation schema for Visual Studio 2008 and Visual Web Developer is for downloading. Follow the instructions posted on the page to install the new scheme. Seems like the Visual Studio Team will be supporting HTML 5 after all.

• Setting up Ruhoh. ERROR: repository not found

  - by user1637613

  Instructions from ruhoh.com state to setup a repository USERNAME.ruhoh.com, which has been done. https://github.com/NredYssuts/nredyssuts.ruhoh.com also asks to add a web hook, which has also been done. Then it gives the following instructions to execute: $ git clone git://github.com/ruhoh/blog.git USERNAME.ruhoh.com $ cd USERNAME.ruhoh.com $ git remote set-url origin [email protected]:USERNAME/USERNAME.ruhoh.com.git $ git push origin master I am able to execute the first three lines and then on the fourth I am asked to enter my passphrase for /home/nredyssuts/.ssh/id_rsa I do that correctly and then bam! ERROR: Repository not found. fatal: the remote end hung up unexpectedly I'm not sure why this is happening at all. This is a public repository.

• Best way to convert between [Char] and [Word8]?

  - by cmars232

  I'm new to Haskell and I'm trying to use a pure SHA1 implementation in my app (Data.Digest.Pure.SHA) with a JSON library (AttoJSON). AttoJSON uses Data.ByteString.Char8 bytestrings, SHA uses Data.ByteString.Lazy bytestrings, and some of my string literals in my app are [Char]. This article seems to indicate this is something still being worked out in the Haskell language/Prelude: http // hackage.haskell.org/trac/haskell-prime/wiki/CharAsUnicode And this one lists a few libraries but its a couple years old: http //blog.kfish.org/2007/10/survey-haskell-unicode-support.html [Links broken because SO doesn't trust me -- whatever...] What is the current best way to convert between these types, and what are some of the tradeoffs? I don't want to pick something that is obsolete... Thanks!

• .htaccess setting is not working on Google Chrome

  - by Zack

  I am using CakePHP framework, it redirect everything to the app folder using .htaccess, and then I set up a WordPress blog in /news/ folder outside of CakePHP, so I don't want everything in /news/ to be redirect, so I modify the .htaccess, and here is the final version: <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_URI} ^/news/(.*)$ RewriteRule ^.*$ - [L] </IfModule> <IfModule mod_rewrite.c> RewriteEngine on RewriteBase / RewriteRule ^$ app/webroot/ [L] RewriteRule (.*) app/webroot/$1 [L] </IfModule> It's working fine in IE and FireFox, I can visit mydomain/news/, but in Google Chrome, it still redirects to CakePHP app folder. How can I fix this?

• jQuery sanitizing comments and linkifying URLs

  - by iWasRobbed

  In terms of jQuery (or Javascript), what happens behind the scenes when a person posts a comment on Facebook, Twitter, or a blog? For instance, do they sanitize the text first, and then pattern match URL's into an actual link? Are there other items of concern that the client-side should check in addition to doing some checks on the backend? I have found a few regex's for turning URL's into links, but I'm not sure if there are better solutions. I'm trying to wrap my head around the problem, but I'm having a difficult time knowing where to start. Any guidance you can provide is greatly appreciated!

• Getting started developing for iPhone

  - by mikemoosey

  Hey all, quick question. My end goal is to start developing apps for the iPhone but my current skillset is pretty limited. I'm wondering how far back I should go back and where I should start as far as becoming familiar with coding before the iPhone SDK course on Lynda.com isn't something that makes my eyes glaze over. My experience: I taught myself html from the html for dummies book maybe 10 years ago, I've taken a dreamweaver class and built a few sites with it, and I've customized a self hosted Wordpress blog by playing with the php code. Any tips on where I should start if I want to head down the road toward developing for the iPhone? Thanks!

• [WordPress 3.1.3] Sreen option is disabled when a plugin is activated

  - by RNorbe

  I'm pretty new to wordpress. I was assigned to create a custom plugin for one of our projects here. The plugin worked as expected and there is no problem activating/deactivating it. When I was exploring the admin panel I noticed that the screen option is off. I read from a blog somewhere that deactivating the plugin one by one to check which plugin has caused this. I did just this and found out that the custom plugin I created was the cause. My question is, is there way to check what have caused this? Some log file I can look into? There is no error message or warning when I activated the plugin and it is giving the output required. This is my first plugin, any advice will be helpful. Btw, this plugin will display a comment (most recent will be shown first) in a widget and there is prev/next navigation to go through the rest of the comments. Thanks, RNorbe

• : for displaying all elements in a multidimensional array in python 3.1.

  - by Leif Andersen

  I have a multidimensional array in python like: arr = [['foo', 1], ['bar',2]] Now, if I want to print out everything in the array, I could do: print(arr[:][:]) Or I could also just do print(arr). However, If I only wanted to print out the first element of each box (for arr, that would be 'foo', 'bar'), I would imagine I would do something like: print(arr[:][0]) however, that just prints out the first data blog (['foo', 1]), also, I tried reversing it (just in case): print(arr[0][:]) and I got the same thing. So, is there anyway that I can get it to print the first element in each tuple (other than: for tuple in arr: print(tuple[0]) )? Thanks.

• Recover a deleted webpage

  - by rc

  Suppose, a blog or a nice article was hosted on a website and it got deleted or worse the website was brought down. How do you view that web page? I tried searching for the cached version in Google. But, looks like the content was deleted long ago and is not listed in the search results directly. There are annotations to the link from many other sites, but still the actual content is not fully available. Now, can anybody help me see this page... I am actually looking for http://effectize.com/become-coolest-programmer :) And, moreover, in addition to bookmarking a favorite link, is it possible to cache the content of the link as well for later reference in case it gets deleted? EDIT: Looks like a URL can be cached for future reference. Try: http://backupurl.com/
