• Models, controllers, and code reuse

  - by user11715

  I have a blog where users can post comments. When creating a comment, various things happen: creating the comment object, associations, persisting sending notification emails to post's author given his preferences sending notification to moderators given their preferences updating a fulltext database for search ... I could put all this in the controller, but what if I want to reuse this code ? e.g. I would like to provide an API for posting comments. I could also put this in the model, but I wonder if I won't lose flexibility by doing so. And would it be acceptable to do all of this from the model layer ? What would you do ?

  I am looking for a good comparision of different available professionial requirement managment tools. I am especially interested in the the features available within the different software solutions. Additionally to the "obvious" features I am looking for a proffesional Requirement Management System that supports for: multi-lingual customizable generation of documentation & history (graphs) search features (e.g. fulltext for comments), ordering, priorities version history bi-directional traceability of changes, artefacts, requirements, changes in requirements, etc. Any kind of integration of V-Model XT would be a really-nice-to-have-feature...

• Extracting main article from webpage/feed. Is it legal/ethical?

  - by Mahdi Ghiasi

  There are some applications like Readability and Pocket, which are letting users to read the main content of web pages, in a clean interface or such. But the articles should be bookmarked from another application, or the web browser. However, I'm creating a news reader app (Zite and Flipboard are popular news reader apps), and I want to create a clean experience for users, so I want to show full content of articles inside my application. Some websites have fulltext feeds, and I'm using it. But about some other websites, which don't have full text feeds: I want to know, is it legal/ethical to use for example Readability API (Or maybe writing my own code for this) to show full text of articles inside my application?

• Why googling by keycaptcha gives results on reCAPTCHA? [closed]

  - by vgv8

  EDIT: I'd like to change this title to: How to STOP Google's manipulation of Google search engine presented to general public? I am frequently googling and more and more frequently bump when searching by one software product I am given instead the results on Google's own products. For ex., if I google by keyword keycaptcha for the "Past 24 hours" (after clicking on "Show search tools" -- "Past 24 hours" on the left sidebar of a browser) I am getting the Google's search results show only results on reCAPTCHA. Image uploaded later: Though, if confine keycaptcha in quotes the results are "correct" (well, kind of since they are still distorted in comparison with other search engines). I checked this during few months from different domains at different ISPs, different operating systems and from a dozen of browsers. The results are the same. Why is it and how can it be possibly corrected? My related posts: "How Gmail spam filter works?" IP adresses blacklisting Update: It is impossible for me to directly start using google.com as I am always redirected to google.ru (from google.com) by my ip-address "auto-detect location" google's "convenience". The google's help tells that it is impossible to switch off my location auto-detection because it is very helpful feature. There is a work-around to use google.com/ncr (to get google.com) (?anybody know what does it mean) to prevent redirection from google.com but even. But all results are exactly the same OK, I can search by quoted "keycaptcha", I am already accustomed to these google's quirks, but the question arises why the heck to burn time promoting someone's product if GOOGLE uses other product brands for showing its own interests/brands (reCAPTCHA) instead and what can be done with it? The general user will not understand that he was cheated and just will pick up the first (wrong) results Update2: Note that this googling behaviour: is independent on whether I am logged-in (or log-out-ed of) a google account, which account, on browser (I tried Opera, Chrome, FireFox, IE of different versions, Safari), OS or even domain; there are many such cases but I just targeted one concrete restricted example speciffically to to prevent wandering between unrelated details and peculiarities; @Michael, first it is not true and this text contains 2 links for real and significant results.. I also wrote that this is just one concrete example from many and based on many-month exp. These distortions happen upon clicking on: Past 24 hours, Past week, Past month, Past year in many other keywords, occasions/configurations of searches, etc. Second, the absence of the results is the result and there is no point to sneakingly substitute it by another unsolicited one. It is the definition of spam and scam. 3d, the question is not abt workarounds like how to write search queries or use another searching engines. The question is how to straighten the googling's results in order to stop disorienting general public about. Update: I could not understand: nobody reproduces the described by me behavior (i.e. when I click "Past 24 hours" link in google search searching for keycaptcha, the presented results are only on reCAPTCHA presented)? Update: And for the "Past week":

• grep --exclude/--include syntax (do not grep through certain files)

  - by Piskvor

  I'm looking for the string "foo=" (without quotes) in text files in a directory tree. It's on a common Linux machine, I have bash shell: grep -ircl "foo=" * In the directories are also many binary files which match "foo=". As these results are not relevant and slow down the search, I want grep to skip searching these files (mostly JPEG and PNG images): how would I do that? I know there are the --exclude=PATTERN and --include=PATTERN options, but what is the pattern format? manpage of grep says: --include=PATTERN Recurse in directories only searching file matching PATTERN. --exclude=PATTERN Recurse in directories skip file matching PATTERN. Searching on grep include, grep include exclude, grep exclude and variants did not find anything relevant If there's a better way of grepping only in certain files, I'm all for it; moving the offending files is not an option, I can't search only certain directories (the directory structure is a big mess, with everything everywhere). Also, I can't install anything, so I have to do with common tools (like grep or the suggested find). UPDATES: @Adam Rosenfield's answer is just what I was looking for: grep -ircl --exclude=*.{png,jpg} "foo=" * @rmeador's answer is also a good solution: grep -Ir --exclude="*\.svn*" "pattern" * It searches recursively, ignores binary files, and doesn't look inside Subversion hidden folders.(...)

• Learning libraries without books or tutorials

  - by Kawili-wili

  While many ask questions about where to find good books or tutorials, I'd like to take the opposite tack. I consider myself to be an entry-level programmer ready to move up to mid-level. I have written code in c, c++, c#, perl, python, clojure, vb, and java, so I'm not completely clueless. Where I see a problem in moving to the next level is learning to make better use of the literally hundreds upon hundreds of libraries available out there. I seem paralyzed unless there is a specific example in a book or tutorial to hand-hold me, yet I often read in various forums where another programmer attempts to assist with a question. He/she will look through the docs or scan the available classes/methods in their favorite IDE and seem to grok what's going on in a relatively short period of time, even if they had no previous experience with that specific library or function. I yearn to break the umbilical chord of constantly spending hour upon hour searching and reading, searching and reading, searching and reading. Many times there is no book or tutorial, or if there is, the discussion glosses over my specific needs or the examples shown are too far off the path for the usage I had in mind or the information is outdated and makes use of deprecated components or the library itself has fallen out of mainstream, yet is still perfectly usable (but no docs, books, or tutorials to hand-hold). My question is: In the absence of books or tutorials, what is the best way to grok new or unfamiliar libraries? I yearn to slicken the grok path so I can get down to the business of doing what I love most -- coding.

• Finding the Column Index for a Specific Value

  - by Btibert3

  Hi All, I am having a brain cramp. Below is a toy dataset: df <- data.frame( id = 1:6, v1 = c("a", "a", "c", NA, "g", "h"), v2 = c("z", "y", "a", NA, "a", "g"), stringsAsFactors=F) I have a specific value that I want to find across a set of defined columns and I want to identify the position it is located in. The fields I am searching are characters and the trick is that the value I am looking for might not exist. In addition, null strings are also present in the dataset. Assuming I knew how to do this, the variable position indicates the values I would like returned. > df id v1 v2 position 1 1 a z 1 2 2 a y 1 3 3 c a 2 4 4 <NA> <NA> 99 5 5 g a 2 6 6 h g 99 The general rule is that I want to find the position of value "a", and if it is not located or if v1 is missing, then I want 99 returned. In this instance, I am searching across v1 and v2, but in reality, I have 10 different variables. It is also worth noting that the value I am searching for can only exist once across the 10 variables. What is the best way to generate this recode? Many thanks in advance.

• Disable a form and all contained elements until an ajax query completes (or another solution to prev

  - by Max Williams

  I have a search form with inputs and selects, and when any input/select is changed i run some js and then make an ajax query with jquery. I want to stop the user from making further changes to the form while the request is in progress, as at the moment they can initiate several remote searches at once, effectively causing a race between the different searches. It seems like the best solution to this is to prevent the user from interacting with the form while waiting for the request to come back. At the moment i'm doing this in the dumbest way possible by hiding the form before making the ajax query and then showing it again on success/error. This solves the problem but looks horrible and isn't really acceptable. Is there another, better way to prevent interaction with the form? To make things more complicated, to allow nice-looking selects, the user actually interacts with spans which have js hooked up to them to tie them to the actual, hidden, selects. So, even though the spans aren't inputs, they are contained in the form and represent the actual interactive elements of the form. Grateful for any advice - max. Here's what i'm doing now: function submitQuestionSearchForm(){ //bunch of irrelevant stuff var questionSearchForm = jQuery("#searchForm"); questionSearchForm.addClass("searching"); jQuery.ajax({ async: true, data: jQuery.param(questionSearchForm.serializeArray()), dataType: 'script', type: 'get', url: "/questions", success: function(msg){ //more irrelevant stuff questionSearchForm.removeClass("searching"); }, error: function(msg){ questionSearchForm.removeClass("searching"); } }); return true; }

  Hello I'm searching for answer how to put programs (not program) in context menu of desktop at one context name?

  Hello, I've got an input box that allows UTF8 characters -- can I detect whether the characters are in Chinese, Japanese, or Korean programmatically (part of some Unicode range, perhaps)? I would change search methods depending on if MySQL's fulltext searching would work (it won't work for CJK characters). Thanks!

• Fourier transform software

  - by CFP

  Hello everyone! After spending a lot of time searching for this, I thought that some SuperUser gurus might know the answer :) I'm searching for an open source application to compute an FFT, that could: * Import a list of points from a text file (in any format, I could write conversion scripts if needed), for example 0,1; 1,2; 4,5 * Compute the associated discrete transform, and output the list of coefficients Ideally, it would also display the plot and the associated fourier decomposition on the same graph, to allow comparison, but this is not absolutely needed. It can be either on Windows or on Linux/Unix. Can you think of a solution? Thanks, CFP.

• Fetch excerpt from Wikipedia article?

  - by Felix

  I've been up and down the Wikipedia API, but I can't figure out if there's a nice way to fetch the excerpt of an article (usually the first paragraph). It would be nice to get the HTML formatting of that paragraph, too. The only way I currently see of getting something that resembles a snippet is by performing a fulltext search (example), but that's not really what I want (too short). Is there any other way to fetch the first paragraph of a Wikipedia article than barbarically parsing HTML/WikiText?

• Where to find and download a new suitable software? [closed]

  - by user63411

  Possible Duplicate: How do you find a new software to download? I see that the most time I spend on the computer I lose to just searching for suitable software. How you do it? What is your way to find software? Do you first go to a forum or google? Which torrent site? which P2P program, website or server? For example: "I need a software that have functions as a remote desktop and also lets you copy and paste (drag and drop - file manager). And after few hours searching on Google I downloaded LOGMEIN Pro2, but than I see that is just trial. So if I need to find alternative I will spend another whole day. Where to go? I am not an amateur but I need a better system. I need better introduction on how to find what is the suitable software.

  I have a very specific question, which I have not been able to find the solution I want to search Superuser and other websites using Google, but I want to limit it to a specific subject (e.g. the R programming language). Using Superuser paths for specific topics like "site:http://superuser.com/questions/tagged/r" Does not work, as can be seen when comparing searching using full path compared to searching entire website with more specific question. Also note the first hit being one step in the direction i want, but since this path itself does not hold the questions in its path it does not solve my issue. There should however be a better way to do this, e.g. by having a very specific Google search tag for the R programming language, which would have to be either in the path, on the webpage, or tagged differently. Seeing as Superuser has a good tag system I am optimistic that this can be used to solve my question. Is there a solution to this that always works on Superuser and similar sites?

• Du Meter Log file

  - by Jack

  Where can I find the Du Meter Log file? I tried searching C:\ProgramData\Hagel Technologies\DU Meter but the folder is empty. I also tried C:\Users\Username\AppData\Roaming and Local and LocalLow but none of them even have a Du Meter or Hagel Technologies folder. I even tried searching the temp folder but still nothing. I have a NetMeter.csv log file that I want to try and replace over the Du Meter log file cause I can't seem to find any other way to import data into Du Meter.

• backup, sync and search files over internet and intranet

  - by Cawas

  There are many online backup options out there. Dropbox, Sugarsync, Mozy, Carbonite, Jungledisk and my favorite so far, Crashplan. Some of them allow searching, all of them sync with their online servers, none of those (or many many others I didn't listed here) have what I want. I'm _not_ looking for an online backup service in here. Sure, some people might say "use rsync", "linux" and/or "set up apache" and so on... But that's just too much for maintenance, if it's even viable of building up. It needs to be simple. So, anyone knows of a really good solution out there? Picture mostly Google Desktop Search (or quick search) awesome searching, mixed with Crashplan Desktop, which is able to do everything by itself, and something like Dropbox's file versioning, along with dropbox the ability to seamless sync over intranet and internet like crashplan, switching between them when needed. I bet there's nothing like this yet, but well, I'm not sure. It would be great!
