  • Google doesn't seem to update the description or title of my homepage

    - by Dayson
    Before we launched our website, we had set up a "coming soon" page and google picked up the title and description from its contents. So the description in the search results said, "Coming soon! Visit epicwhale.org for updates." It's been a few weeks since we launched our website. We've even created a sitemap and submitted it to google. In the google webmaster panel, the pages have been crawled and all the pages are appearing as expected on google, EXCEPT the homepage which is still not updated! The title and description of the homepage in google search results still says coming soon.. The website I am referring to is textmewidget.com and below are the images of the search result. Google: http://i.imgur.com/vAkJg.png I checked on bing too, but it appears to be fine there. Bing: http://i.imgur.com/Q8O6L.png All other pages seem to be indexed fine on google. I don't even have any crawl errors in my reports. So what seems to be the problem? I've already waited for 2 weeks. Thanks in advance!

  • Microeconomical simulation: coordination/planning between self-interested trading agents

    - by Milton Manfried
    In a typical perfect-information strategy game like Chess, an agent can calculate its best move by searching the state tree for the best possible move, while assuming that the opponent will also make the best possible move (i.e. Mini-max). I would like to use this approach in a "game" modeling economic activity, where the possible "moves" would be to buy or sell for a given price, and the goal, rather than a specific class of states (e.g. Checkmate), would be to maximize some function F of the agent's state (e.g. F(money, widget) = 10*money + widget). How to handle buy/sell actions that require coordination between both parties, at the very least agreement upon a price? The cheap way out would be to set the price beforehand, maybe based upon the current supply -- but the idea of this simulation is to examine how prices emerge when freely determined by "perfectly rational" agents. A great example of what I do not want is the trading algorithm in SugarScape -- paraphrasing from Growing Artificial Societies p101-102: when a pair of agents interact to trade, they each compute their internal valuations of the goods, then a bargaining process is conducted and a price is agreed to. If this price makes both agents better off, they complete the transaction The protocol itself is beautiful, but what it cannot capture (as far as I can tell) is the ability for an agent to pay more than it might otherwise for a good, because it knows that it can sell it for even more at a later date -- what appears to be called "strategic thinking" in this pape at Google Books Multi-Agent-Based Simulation III: 4th International Workshop, MABS 2003... to get realistic behavior like that, it seems one would either (1) have to build an outrageously-complex internal valuation system which could at best only cover situations that were planned for at compile-time, or otherwise (2) have some mechanism to search the state tree... which would require some way of planning future trades. Note: The chess analogy only works as far as the state-space search goes; the simulation isn't intended to be "zero sum", so a literal mini-max search wouldn't be appropriate -- and ideally, it should work with more than two agents.

  • Impact on SEO of adding categories/tags in front of the HTML title [closed]

    - by Mad Scientist
    Possible Duplicate: Does the order of keywords matter in a page title? All StackExchange sites add the most-used tag of a question in front of the HTML title for SEO purposes. On Stackoverflow for example this is usually the programming language, so you end up with a title like python - How do I do X? This has obviously an enourmous benefit on SEO as the programming language is an extremely important keyword that is very often omitted from the title. Now, my question is for the cases where the tag isn't an important keyword missing from the title, but just a category. So on Biology.SE for example one would have questions like biochemistry - How does protein X interact with Y? or on Skeptics medical science - Do vaccines cause autism? Those tags are usually not part of the search terms, they serve to categorize the content but users don't use those tags in their searches. How harmful is adding tags that are not used in searches in terms of SEO? Is there any hard data on the impact this practise might have on SEO? The negative aspects I can imagine, but have no data to show that it is actually a problem are: I heard that search engines dislike keyword stuffing and this might trigger some defense mechanisms against that It's a practise associated with less reputable sites, a keyword in front that doesn't fit the actual title well might look suspicious to some users. It wastes precious space in the title shown in search results.

  • Is this paragraph in Code Complete 2 backwards, or am I misunderstanding it?

    - by user828584
    In chapter 13, when talking about pointers, there is a paragraph: Sometimes, however, you would like to have the semantics of pass by reference—that is, that the passed object should not be altered—with the implementation of pass by value—that is, passing the actual object rather than a copy. It seems like the author made a mistake and mixed the two up. Is this true, or am I not understanding what he's saying correctly?

  • Refactoring obscurely commented code

    - by wraith808
    In refactoring code, I came across code that had comments. Looking closer at the comments, I could see that the code was clearly not doing what the comments said. Without access to the coder nor documentation, and without clear direction regarding the code (i.e. defects as to the fact that the code is operating incorrectly), is the best practice to assume that the code is correct, and clean up the comments?

  • How much should I rely on Visual Studio's Auto Generated Code?

    - by Ant
    So I'm reading up on ASP.NET with VB.NET and I want to start making my own, professionally built website using ASP. I'm wondering though; I'm still using the basics so I'm really just a novice, but how much should I rely on Visual Studio to create my elements? Should I make my own text boxes and have my own login routine, or should I just use ASP's login features? I know eventually you have to use your own classes and such which is where the real coding comes in, but I'm not sure how relaible, flexible and secure the pre-wrote elements are? Any help would be greatly appreciated.

  • Getting rank for keywords that I don't want to appear on my website [duplicate]

    - by Rober
    This question already has an answer here: Which keyword should I use. colors or colours or a combination of both? 2 answers One of my products has two names. One of them is what I consider correct and thus it is what I want to appear on my website. The other name is incorrect for me, so I would like to avoid it. But I know that many people will search my product using the "bad" name. How could I get the "bad" name indexed for my site on search engines even if nobody can read it there? Of course, I want to do it "legally" so that no engine will ban my site considering it as cloaking, black hat SEO, etc... EDIT: Having that "bad" name on my backlinks is not an option. For example I would perceive user reviews connecting my site to that word as a negative point. Maybe having my site as a search result for that word could be negative as well, but I think it is worth it.

  • Why do my websites have a first page rank on Bing and Yahoo but not Google? [closed]

    - by Linda Cullum
    I have 3 websites suffering from a drop in ranking with Google and hence a huge drop in traffic. The instant drop ocurred in September and I have not been able to remedy it. For the past 6-10 years my main website http://LearnToSail.Net has ranked from #3 to #1 on the 1st page of Google and all the other engines with the search term "learn to sail" Now it shows on the 1st page of Bing and Yahoo but does not show up on ANY pages of Google. The only way it does come up is if I add "cd" to the "learn to sail" phrase. We sell a sailing cd on that website. The other websites are http://LearnToSailOnLine.com ..search terms are "learn to sail online" or learntosailonline and historyofthepilgrims.com search terms are "history of the pilgrims" "historyofthepilgrims" I get the same result. Gone on Google but 1st pages for Bing and Yahoo. I have researched, edited,updated blogs, made sitemaps, prayed to the universe and use Google Webmaster tools but nothing is changing and I have lost alot of business. I host with 1and1.com and have been back and forth with them but to no avail and no change in traffic. I thought maybe some DNS mapping was off. I used to have alot of traffic now I have hardly any. Any advice would be greatly appreciated. I am still in the process of working on the issue of course! This is a really great website here and I am glad I came across it. Thank you, LS Cullum Little Pines Multimedia

  • Comments in code

    - by DavidMadden
    It is a good practice to leave comments in your code.  Knowing what the hell you were thinking or later intending can be salvation for yourself or the poor soul coming behind you.  Comments can leave clues to why you chose one approach over the other.  Perhaps staged re-engineering dictated that coding practices vary.One thing that should not be left in code as comments is old code.  There are many free tools that left you version your code.  Subversion is a great tool when used with TortoiseSVN.  Leaving commented code scattered all over will cause you to second guess yourself, all distraction to the real code, and is just bad practice.If you have a versioning solution, take time to go back through your code and clean things up.  You may find that you can remove lines and leave real comments that are far more knowledgeable than having to remember why you commented out the old code in the first place.

  • Incremental search in Visual Studio

    - by Jalpesh P. Vadgama
    Visual studio is a Great IDE and there are still lots of feature that not known to developers. Incremental search is one of them. This is a amazing feature to find code in particular document and its available from Visual Studio 2010 and carried over in Visual Studio 2012. Incremental search allows developers to search in document without blocking UI and allow to search as they type. Interesting!! right.. So let’s open visual studio and see how it works. Once you open Visual Studio and press Ctrl + I and type something it will find the string without blocking your visual studio UI. Just like following. In the above code you can see that, I have typed Cons and You can see that whole console word is highlighted. Even you can see that find dialog box on top right corner of visual studio 2012 like following. Same way if you see the footer in visual studio where it is finding cons in current document like following. Isn’t that great now we find things very easily and we don’t have to remember whole word like Console. Hope you like it. Stay tuned for more updates.

  • Best method to implement a filtered search

    - by j0N45
    I would like to ask you, your opinion when it comes to implement a filtered search form. Let's imagine the following case: 1 Big table with lots of columns It might be important to say that this SQL Server You need to implement a form to search data in this table, and in this form you'll have several check boxes that allow you to costumize this search. Now my question here is which one of the following should be the best way to implement the search? Create a stored procedure with a query inside. This stored procedure will check if the parameters are given by the application and in the case they are not given a wildcard will be putted in the query. Create a dynamic query, that is built accordingly to what is given by the application. I am asking this because I know that SQL Server creates an execution plan when the stored procedure is created, in order to optimize its performance, however by creating a dynamic query inside of the stored procedure will we sacrifice the optimization gained by the execution plan? Please tell me what would be the best approach in your oppinion.

  • Trouble with Code First DatabaseGenerated Composite Primary Key

    - by Nick Fleetwood
    This is a tad complicated, and please, I know all the arguments against natural PK's, so we don't need to have that discussion. using VS2012/MVC4/C#/CodeFirst So, the PK is based on the date and a corresponding digit together. So, a few rows created today would be like this: 20131019 1 20131019 2 And one created tomorrow: 20131020 1 This has to be automatically generated using C# or as a trigger or whatever. The user wouldn't input this. I did come up with a solution, but I'm having problems with it, and I'm a little stuck, hence the question. So, I have a model: public class MainOne { //[Key] //public int ID { get; set; } [Key][Column(Order=1)] [DatabaseGenerated(DatabaseGeneratedOption.None)] public string DocketDate { get; set; } [Key][Column(Order=2)] [DatabaseGenerated(DatabaseGeneratedOption.None)] public string DocketNumber { get; set; } [StringLength(3, ErrorMessage = "Corp Code must be three letters")] public string CorpCode { get; set; } [StringLength(4, ErrorMessage = "Corp Code must be four letters")] public string DocketStatus { get; set; } } After I finish the model, I create a new controller and views using VS2012 scaffolding. Then, what I'm doing is debugging to create the database, then adding the following instead of trigger after Code First creates the DB [I don't know if this is correct procedure]: CREATE TRIGGER AutoIncrement_Trigger ON [dbo].[MainOnes] instead OF INSERT AS BEGIN DECLARE @number INT SELECT @number=COUNT(*) FROM [dbo].[MainOnes] WHERE [DocketDate] = CONVERT(DATE, GETDATE()) INSERT INTO [dbo].[MainOnes] (DocketDate,DocketNumber,CorpCode,DocketStatus) SELECT (CONVERT(DATE, GETDATE ())),(@number+1),inserted.CorpCode,inserted.DocketStatus FROM inserted END And when I try to create a record, this is the error I'm getting: The changes to the database were committed successfully, but an error occurred while updating the object context. The ObjectContext might be in an inconsistent state. Inner exception message: The object state cannot be changed. This exception may result from one or more of the primary key properties being set to null. Non-Added objects cannot have null primary key values. See inner exception for details. Now, what's interesting to me, is that after I stop debugging and I start again, everything is perfect. The trigger fired perfectly, so the composite PK is unique and perfect, and the data in other columns is intact. My guess is that EF is confused by the fact that there is seemingly no value for the PK until AFTER an insert command is given. Also, appearing to back this theory, is that when I try to edit on of the rows, in debug, I get the following error: The number of primary key values passed must match number of primary key values defined on the entity. Same error occurs if I try to pull the 'Details' or 'Delete' function. Any solution or ideas on how to pull this off? I'm pretty open to anything, even creating a hidden int PK. But it would seem redundant. EDIT 21OCT13 [HttpPost] public ActionResult Create(MainOne mainone) { if (ModelState.IsValid) { var countId = db.MainOnes.Count(d => d.DocketDate == mainone.DocketNumber); //assuming that the date field already has a value mainone.DocketNumber = countId + 1; //Cannot implicitly convert type int to string db.MainOnes.Add(mainone); db.SaveChanges(); return RedirectToAction("Index"); } return View(mainone); } EDIT 21OCT2013 FINAL CODE SOLUTION For anyone like me, who is constantly searching for clear and complete solutions. if (ModelState.IsValid) { String udate = DateTime.UtcNow.ToString("yyyy-MM-dd"); mainone.DocketDate = udate; var ddate = db.MainOnes.Count(d => d.DocketDate == mainone.DocketDate); //assuming that the date field already has a value mainone.DocketNumber = ddate + 1; db.MainOnes.Add(mainone); db.SaveChanges(); return RedirectToAction("Index"); }

    The UISearchDisplayController is very handy and implementing search is pretty straightforward. However, I bump into problem when, in my app, I want to display search result with empty search string but selected scope button. It seems like it's a must to enter some search string in order to get the search result table being initialized and displayed. Is there any ways to display search result immediately after user has picked a scope but not entered search word yet? Thanks Bill

  • One click to trigger several search forms?

    - by Christian
    Hello, I have 1 main search form with a submit button and several secondary search forms with submit buttons. What I would like to do is when I enter text and click on the submit button of the main search form, the same text gets copied in all of the secondary search forms and all the submit buttons of the secondary search forms get automatically hit. The HTML code for the mains earch form is shown below: <form action="query.php" method="get"> Search: <input type="text" name="item" size="30"> <input type="submit" value="send"> </form> One of the several secondary search forms is shown below: <FORM action="http://www.dpbolvw.net/interactive" method="GET" target="_blank"> <div style="float: left; padding: 0 3px 0 0;"> <INPUT type="text" name="src" size="9" value="<?php $input = $_GET['item']; echo $input;?>" style="width: 110px; height: 22px;margin:0; padding: 0; font-size:140%;"> </div> <div style="float: left; padding: 0 3px 0 0;"> <input type="image" name="submit" value="GO" src="http://images.guitarcenter.com/Content/GC/banner/go.gif" alt="Search" style="font-size:140%"> /div> <input type="hidden" name="aid" value="1234"/> <input type="hidden" name="pid" value="1234"/> <input type="hidden" name="url" value="http://www.guitarcenter.com/Search/Default.aspx"/> </form> Notice the php code that I put in the "value" field of the secondary search form: <?php $input = $_GET['item']; echo $input;?> This automatically copies the text that I entered in the main search form into the secondary search form. I thus figured out how to do that. The problem is to "simulate" an "Enter" keystroke or a click on the "GO" button with the mouse on the secondary search form when the user hits the Enter key or hits the "SEND" button with the mouse on the main search form. Thank you for your insight!

  • QR Code encoding and decoding using zxing

    - by helixed
    Okay, so I'm going to take the off chance that someone here has used zxing before. I'm developing a Java application, and one of the things it needs to do is encode a byte array of data into a QR Code and then decode it at a later time. Here's an example of what my encoder looks like: byte[] b = {0x48, 0x45, 0x4C, 0x4C, 0x4F}; //convert the byte array into a UTF-8 string String data; try { data = new String(b, "UTF8"); } catch (UnsupportedEncodingException e) { //the program shouldn't be able to get here return; } //get a byte matrix for the data ByteMatrix matrix; com.google.zxing.Writer writer = new QRCodeWriter(); try { matrix = writer.encode(data, com.google.zxing.BarcodeFormat.QR_CODE, width, height); } catch (com.google.zxing.WriterException e) { //exit the method return; } //generate an image from the byte matrix int width = matrix.getWidth(); int height = matrix.getHeight(); byte[][] array = matrix.getArray(); //create buffered image to draw to BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB); //iterate through the matrix and draw the pixels to the image for (int y = 0; y < height; y++) { for (int x = 0; x < width; x++) { int grayValue = array[y][x] & 0xff; image.setRGB(x, y, (grayValue == 0 ? 0 : 0xFFFFFF)); } } //write the image to the output stream ImageIO.write(image, "png", outputStream); The beginning byte array in this code is just used to test it. The actual byte data will be varied. Here's what my decoder looks like: //get the data from the input stream BufferedImage image = ImageIO.read(inputStream); //convert the image to a binary bitmap source LuminanceSource source = new BufferedImageLuminanceSource(image); BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(source)); //decode the barcode QRCodeReader reader = new QRCodeReader(); Result result; try { result = reader.decode(bitmap, hints); } catch (ReaderException e) { //the data is improperly formatted throw new MCCDatabaseMismatchException(); } byte[] b = result.getRawBytes(); System.out.println(ByteHelper.convertUnsignedBytesToHexString(result.getText().getBytes("UTF8"))); System.out.println(ByteHelper.convertUnsignedBytesToHexString(b)); convertUnsignedBytesToHexString(byte) is a method which converts an array of bytes in a string of hexadecimal characters. When I try to run these two blocks of code together, this is the output: 48454c4c4f 202b0b78cc00ec11ec11ec11ec11ec11ec11ec Clearly the text is being encoded, but the actual bytes of data are completely off. Any help would be appreciated here. Thanks, helixed

  • Code Sign error: The identity 'iPhone Developer: x Xxxxx' doesn't match any identity in any profile

    - by Cal
    I get this build error when I build my iPhone project to run on my device: Code Sign error: The identity 'iPhone Developer: x Xxxxx' doesn't match any identity in any profile My development code signing certificate expired so I got a new one. On my first attempt I created a new CSR and got the message above. The second time I reused my original CSR and got the same result. Another strange thing is the new certificate has an extra string with brackets after my name in the "common name" when I look at it using Keychain Access like this: iPhone Developer: x Xxxxx (3BDUAJYC9Q) My original certificate didn't have that. I have Xcode Version 3.1.3 Component versions Xcode IDE: 1191.0 Xcode Core: 1192.0 ToolSupport: 1186.0 Does anyone know how to solve this?

  • Making ehcache read-write for test code and read-only for production code

    - by Rick
    I would like to annotate many of my Hibernate entities that contain reference data and/or configuration data with @Cache(usage = CacheConcurrencyStrategy.READ_ONLY) However, my JUnit tests are setting up and tearing down some of this reference/configuration data using the Hibernate entities. Is there a recommended way of having entities be read-write during test setup and teardown but read-only for production code? Two of my immediate thoughts for non-ideal workarounds are: Using NONSTRICT_READ_WRITE, but I am not sure what the hidden downsides are. Creating subclassed entities in my test code to override the read-only cache annotation. Any recommendations on the cleanest way to handle this? (Note: Project uses maven.)

  • Code Golf - p day

    - by gnibbler
    The Challenge The shortest code by character count to display a representation of a circle of radius R using the *character, followed by an approximation of p. Input is a single number, R. Since most computers seem to have almost 2:1 ratio you should only output lines where y is odd. The approximation of p is given by dividing twice the number of * characters by R². The approximation should be correct to at least 6 significant digits. Leading or trailing zeros are permitted, so for example any of 3, 3.000000, 003 is accepted for the inputs of 2 and 4. Code count includes input/output (i.e., full program). Test Cases Input 2 Output *** *** 3.0 Input 4 Output ***** ******* ******* ***** 3.0 Input 8 Output ******* ************* *************** *************** *************** *************** ************* ******* 3.125 Input 10 Output ********* *************** ***************** ******************* ******************* ******************* ******************* ***************** *************** ********* 3.16
