• How can I perform sentiment analysis on extracted text from online sources?

  - by aniket69

  I'm working on extracting the sentiment from YouTube comments, blogs, news content, Facebook wall posts, and Twitter feeds. I'm looking for an automated way to do this: the two third-party solutions I've found have been AlchemyAPI and RapidMiner. Are these the best way to approach this project, or should I be using something else? Is there a more efficient way to approach sentiment analysis? What techniques have worked for you in a project like this?

• robots.txt dissalow url containing string with a '/' at the end

  - by thanili

  i have a website with thousands of dynamic pages. I want to use the robots.txt file in order to dissalow certain url patterns corresponding to pages with duplicate content. For example i have a page for article itemA belonging to category catA/subcatA, with URL: /catA/subcatA/itemA this is the URL that i want to be indexed from google. this article is also visible via tagging in various other places in the web site. The URLs produced via tagging is like: /tagA1/itemA this URL i want NOT to be indexed from google. However i want to have indexed all tag listings: /tagA1 so how can i achieve this? dissalow URLs of including a specific string with a '/' at the end? /tagA1/ itemA - dissalow /tagA1 - allow

• GZipped Images - Is It Worth?

  - by charlie

  Most image formats are already compressed. But in fact, if I take an image and compress it [gzipping it], and then I compare the compressed one to the uncompressed one, there is a difference in size, even though not such a dramatic difference. The question is: is it worth gzipping images? the content size flushed down to the client's browser will be smaller, but there will be some client overhead when de-gzipping it. Please advise.

• Running CLOC (count lines of code) on Windows...or alternative

  - by Chelonian

  I'm trying to use CLOC on Windows (XP) to count lines of code, and I can't get it to work. I downloaded the latest Win installer for CLOC 1.5.6, ran it (which caused a "DOS" window to open, scroll with text rapidly, then close before I could read anything) and then wrote cloc at the cmd prompt...and Windows doesn't recognize it as a command. Or if there is another easy-to-use lines of code counter that one could recommend (that runs on Windows), I'd be happy to try that.

  In those study cases of image storage, An image that change only once in a while, if it changes at all (like an image for an article) The image case from above is not only one image but over 10, that link to the same article An image that have changes very often (like a banner image for a website) The image above is huge What is the best approach for each case? What is the "right/faster" way to do this task in each scenario ?

• How can I compute the Big-O notation for a given piece of code?

  - by TheNew Rob Mullins

  So I just took a data structure midterm today and I was asked to determine the run time, in Big O notation, of the following nested loop: for (int i = 0; i < n-1; i++) { for(int j = 0; j < i; j++2) { //1 Statement } } I'm having trouble understanding the formula behind determining the run time. I thought that since the inner loop has 1 statement, and using the series equation of: (n * (n - 1)) / 2, I figured it to be: 1n * (n-1) / 2. Thus equaling (n^2 - 1) / 2. And so I generalized the runtime to be O(n^2 / 2). I'm not sure this is right though haha, was I supposed to divide my answer again by 2 since j is being upped in intervals of 2? Or is my answer completely off?

• Change from static HTML file to meta tag for Google Webmaster verification

  - by Wilfred Springer

  I started verifying the server by putting a couple of static HTMLs in place. Then I noticed that Google wants you to keep these files in place. I didn't want to keep the static HTMLs in, so I want to switch to an alternative verification mechanism, and include the meta tags on the home page. Unfortunately, once your site is verified, you never seem to be able to change to an alternative way of verification. I tried removing the HTML pages. No luck whatsoever. Google still considers the site to be 'verified'. Does anybody know how to undo this? All I want to do is switch to the meta tag based method of site ownership verification.

• Is there a tool for detecting sites using the same template?

  - by KTB

  I often buy webtemplates online, and when I do so I often look at the demos to get some inspiration on how to use the components. But I would love to look at other sites which have already implemented a full website using this template. So I am looking for a tool which searches sites having a similar HTML as the demos (and therefore are probably implementing the template). I am referring to templates which do not have a static text like "Created with Template FooBar by BarFoo" in the footer.

• Issue with sitemap in GWT

  - by Anusha

  I have an e-commerce website www.beyondtime.in, i have been constantly monitoring the google bot crawling on my website and my webmaster account. Lately, i have found two issues that i have not been able to understand and hence want your help. 1.) The Google Bots have been only crawling www.beyondtime.in/telecom.php this URL of my website, when the URL is not even valid. So, kindly help me understand what needs to be done to let Google crawl other pages of the website as well. 2.) The second question is about the Google Webmaster account, where i've submitted my sitmap with 227 URLs, but out of that only 156 have been indexed. Also none of the images of my website have been indexed by Google. So kindly help me with this as well. Thanks

• JMeter: how to asign a single distinct value from CSV Data Set Config to each thread in thread group?

  - by JohnnyM

  I have to make a load test for a relatively large number of users so I cant realy use User Parameters pre-processor to parametrize each thread with custom user data. I've read that I should use CSV Data Set Config instead. However I run into a problem with how JMeter interprets the input of this Config. Example: I have a thread group of 3 threads and Loop Count:10 with one HTTP request sampler with server www.example.com and path: \${user}. The csv file (bullet is a single line in file) for CSV Data Set Config to extract the user parameter: 1 2 3 4 5 Expected output is that for thread 1-x the path of the request should be: \x. So the output file should consist of 10 samples per thread namely: for thread 1-1 : 10 requests to www.example.com\1 for thread 1-2 : 10 requests to www.example.com\2 for thread 1-3 : 10 requests to www.example.com\3 but instead i get requests to each \1 - \5 and then to EOF. Does anyone know how to achieve the expected effect with CSV Data Set Config in jmeter 2.9?

• New DMV–yes… no… that’s complicated

  - by Michael Zilberstein

  Remember the excitement about new sys.dm_exec_query_profiles DMV? It promised to be a gamechanger, providing query visibility at a runtime and easily extractable information about heavy iterators in execution plan. So it has been announced but missing. Now in CTP2 it is finally here. So, singing one of my favorite Queen songs “… It finally happened - I’m slightly mad…” , I tried to observe query execution data at a runtime. And… nothing. Query is running, DMV is empty. That’s really disappointing...(read more)

• After a domain change, what can I do to recover lost traffic, rankings, impressions etc? [duplicate]

  - by Felix

  This question already has an answer here: How do I rename a domain and preserve PageRank? 3 answers I moved my site to a legacy exact-match domain I purchased about a couple of months ago. I have seen significant reduction in traffic, impressions, and rankings. I did all the right steps/best practices: change of address in GWT, map old site hierarchy and match to new site for 301 redirects etc. Indexation has gone through the Google process: old site has all but dissappeared from he index and new site is indexed, albeit with some 404 errors which I am addressing. Does anyone else who has gone through eh domain change process have any thoughts/advice? Thanks!

• Difference in stats on the same domain - seo related

  - by Duoweb

  Recently i started to optimize my company's website. With a little help of market samurai. One of the adjustments was a www redirect to the prefered domain. We currently rank on #8 for our desired keyword with the domain without the www. If I add a custom url (our domain with www), we see a difference in stats BLP (backlinks to the page) {it's the website on top} Can anyone tell me how i could merge this so we might even rank better for our keyword? What I did so far: 3 weeks ago set the www.duo.be as prefered domain in GWT and put a 301 redirect in place so the duo.be gets redirected to www.duo.be Both domains are in GWT and both with www.duo.be as preferred domain. Tho I see no change. Can anyone help me out, because i'm clueless. Marketsamurai screenshot: http://i.stack.imgur.com/CYkb8.png

• How to find classes that use certain DB tables

  - by Songo

  Problem: I'm asked to prepare a document where all our DB tables are listed and I'm supposed to list all Controllers that uses these DB tables for read and another list for Controllers that do write operations. Ex: +------------------------------------------+------------+ | DB table | tbl_Orders | +------------------------------------------+------------+ |Controllers that perform read operations | ?? | +------------------------------------------+------------+ |Controllers that perform write operations | ?? | +------------------------------------------+------------+ We are trying to write some documentation for a legacy system built using Zend framework. The code is scattered everywhere. There is code in the Controllers, in the models and even in the views. The application uses PROPEL as an ORM. What makes this really difficult is that the Controller may not be directly calling the table, but it may be instantiating a model class that calls that table. Is there an educated way to approach this crazy task? Note: Searching for the table name won't provide a solution because if a model uses that table I wouldn't know which Controller is using that model.

• What does "kTriangles/s" mean in hardware graphics benchmark reports?

  - by swquinn

  I've looked around and found several sites offering benchmarking statistics for mobile platforms and I've been seeing the unit of measure as "kTriangles/s". Originally I misread this, missing the 'k'; does this translate to "thousand(s) of triangles/s", e.g.: 8902 kTriangles/s = 8,902,000 triangles/s (I'm pretty sure that my interpretation is correct, but I hope someone can confirm this for me) Thanks!

• HTML5 - Does it have the power to handle a large 2D game with a huge world?

  - by user15858

  I have been using XNA game studio, but due to private reasons (as well as the ability to publish anywhere & my heavy interest in isogenic engine), I would like to switch to HTML5. However, I have very high 2D graphic demands for my game. The game itself will have a HDD size of anywhere between 6GB (min) to 12GB (max) which would be a full game deployed offline. The size of the images aren't significantly large, so streaming would be entirely possible if only those assets required were streamed as needed. The game has a massive file size because of the sheer amount of content. For some images or spritesheets, they would be quite massive. (ex. a very large Dragon, which if animated in a spritesheet would be split into two 4096x4096 sheets or one 8192x8192 sheet). Most assets would be very small, and about 7MB for a full character with 15 animations in every direction (all animations not required immediately) so in the size of a few hundred KB to download before the game loads. My question, however, is if the graphical power of HTML5 is enough to animate several characters on screen at once, when it flips through frames quite rapidly. All my sprites have about 25 frames per animation, 5 directions (a spritesheet for each direction & animation), and run at 30fps. Upon changing direction, animation, or a new character entering, spritesheets would change and be constantly loading/unloading. If I pack all directions in a single sheet, it would be about 2048x2048 per sheet. Most frameworks have no problem with this, but I am afraid from what I read that HTML5's graphical capabilities will limit me. Since it takes significant time simply to animate characters in any language, I'd like a quick answer.

• Is there a better strategy than relying on the compiler to catch errors?

  - by koan

  I've been programming in C and C++ for some time, although I would say I'm far from being an expert. For some time, I've been using various strategies to develop my code such as unit tests, test driven design, code reviews and so on. When I wrote my first programs in BASIC, I typed in long blocks before finding they would not run and they were a nightmare to debug. So I learned to write a small bit and then test it. These days, I often find myself repeatedly writing a small bit of code then using the compiler to find all the mistakes. That's OK if it picks up a typo but when you start adjusting the parameters types etc just to make it compile you can screw up the design. It also seems that the compiler is creeping into the design process when it should only be used for checking syntax. There's a danger here of over reliance on the compiler to make my programs better. Are there better strategies than this? I vaguely remember some time ago an article on a company developing a type of C compiler where an extra header file also specified the prototypes. The idea was that inconsistencies in the API definition would be easier to catch if you had to define it twice in different ways.

• Database in the cloud?

  - by Jlouro

  Some of my recent clients are asking for remote connections to the office server, for standalone work, etc, in winForm applications. Since the concept of the web is remote connection to a server both of data and resources, it should be possible to place both of this in cloud and have the winForm apps connect to it as if web Apps. As any one tested this, is working like this? Is it fast enough? Is it secure? What is the best cloud host for this type of work ?

• How to run/test JavaScript? [closed]

  - by user702

  I'm reading David Flanagan's "JavaScript: The Definitive Guide, 6th ed". It only actually tells users how to run JS code on page 311, where users are told of the following solutions: "Client-side JavaScript code is embedded within HTML documents in four ways: Inline, between a pair of <script> and </script> tags From an external file specified by the src attribute in a <script> tag In an HTML event handler attribute, such as onclick or onmouseover In a URL that uses the special javascript: protocol." I was wondering what professional JS developers use to write and test their code: Do they use a good text editor with syntax high-lighting + autocompletion, hit F5 in the browser to reload the page every time they make a change, and use some add-on in the browser to investigate errors? Or are there full-fledged IDE's similar to MS VisualStudio for non-web languages?

• Is there a way I can verify my Google Analytics custom report?

  - by SnowboardBruin

  I want to track scrolling on my website since it's a long page (rather than multiple pages). I saw several different methods, with and without an underscore for trackEvent, with and without spaces between commas <script> ... ... ... ga('create', 'UA-45440410-1', 'example.com'); ga('send', 'pageview'); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 100, true]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 75, false]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 50, false]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 25, false]); </script> It takes a day for counts to load with Google Analytics, otherwise I would just tweak and test right now.

• Unity 3D Display Lag

  - by ec2011

  I find that there is quite a lot of lag when using Unity after upgrading to Precise. It seems that when I first start up the computer, everything is fine, but then if I put the computer on standy for a while and then come back to it, the display is extremely slow and there is a significant delay to visual effects that make the system rather cumbersome to use. I tried to report this as a bug but then bug reporting tool directed me to ask this is a question here first. Thanks for any ideas

• Structuring Access Control In Hierarchical Object Graph

  - by SB2055

  I have a Folder entity that can be Moderated by users. Folders can contain other folders. So I may have a structure like this: Folder 1 Folder 2 Folder 3 Folder 4 I have to decide how to implement Moderation for this entity. I've come up with two options: Option 1 When the user is given moderation privileges to Folder 1, define a moderator relationship between Folder 1 and User 1. No other relationships are added to the db. To determine if the user can moderate Folder 3, I check and see if User 1 is the moderator of any parent folders. This seems to alleviate some of the complexity of handling updates / moved entities / additions under Folder 1 after the relationship has been defined, and reverting the relationship means I only have to deal with one entity. Option 2 When the user is given moderation privileges to Folder 1, define a new relationship between User 1 and Folder 1, and all child entities down to the grandest of grandchildren when the relationship is created, and if it's ever removed, iterate back down the graph to remove the relationship. If I add something under Folder 2 after this relationship has been made, I just copy all Moderators into the new Entity. But when I need to show only the top-level Folders that a user is Moderating, I need to query all folders that have a parent folder that the user does not moderate, as opposed to option 1, where I just query any items that the user is moderating. Thoughts I think it comes down to determining if users will be querying for all parent items more than they'll be querying child items... if so, then option 1 seems better. But I'm not sure. Is either approach better than the other? Why? Or is there another approach that's better than both? I'm using Entity Framework in case it matters.

• What amount of PHP memory usage is reasonable for multiple WordPress sites? [closed]

  - by John

  It seems like I've been plagued with memory usage issues most of the time I've been blogging (7 years). I upgraded my hosting to a HostGator VPS and still seem to have issues. I have about a dozen WP 3.4.2 sites running within a single account. Each has a separate installation. I finally installed TPC! Memory Usage within one of my WP installs to see what was going on. The memory usage just standing still is on the order of 40 MB. This seems high, but I don't know. What would be a reasonable memory usage for these WP installs? Do I need to take other things into account, or am I even looking at it the right way?

  Windows and SQL Azure Resources Cloud computing is more than just the latest buzz word in the IT trade papers. It is a remarkable paradigm shift with as much potential to "turn over the apple cart" of IT computing as client-server had for the world of mainframe and minicomputers.
