• navigation menus and SEO

  - by Rodolfo

  I've always have my doubts about navigation menus effect on SEO. You know, the vertical menus on the top that show in every page in the site linking to main sections and subsections. My issue is that if not done dynamically (i.e. after page is loaded or something), from a search engine's point of view it probably looks like a whole bunch of links in the beginning of the page, and links that probably have nothing to do with the page being analyzed, so it's probably not only confusing it, but also giving link 'juice' to the wrong pages or reducing its value. When I've asked SEO people about this, I usually get a "Google is smart, they'll recognize it as a menu and ignore it" response, but I'm not convinced (and the 'Google is smart' argument sounds almost like religion discussion to me). So does it affect SEO negatively or not? Are there any official posts on this topic?

• How can Java be improved so that it no longer needs to perform type erasure? [closed]

  - by user63904

  The official Java tutorial on generics explains type erasure and why it was added to the compiler: When a generic type is instantiated, the compiler translates those types by a technique called type erasure — a process where the compiler removes all information related to type parameters and type arguments within a class or method. Type erasure enables Java applications that use generics to maintain binary compatibility with Java libraries and applications that were created before generics. This most likely was a pragmatic approach, or perhaps the least painful one. However, now that generics is widely supported across the industry, what can be done in order for us to not need type erasure? Is it feasible with out needing to break backwards compatibility, or if it is feasible, is it practical? Has the last the last statement in the quote above become self referential? That is: "type erasure enables Java applications that use generics to maintain binary compatibility with Java libraries and applications that were created with Java versions that perform type erasure."

• What does Enable/Disable mean in Bing's URL Normalization feature?

  - by DisgruntledGoat

  I'm in Bing Webmaster Tools, under Index URL Normalization. Many parameters are listed in the table with 3 other columns: Status, Source, Date. The "Source" column says "Webmaster" where I have added parameters, and "Bing" where I assume the parameter has been auto-detected. "Date" is probably the last date it detected the parameter. I've tried searching the help files but I can't find what the Status column means. The top of the page says: This feature allows you to specify query parameters for Bing’s crawler to ignore. But it's not clear whether "Enable" or "Disable" is related to this, and if so what happens in each case. Does anyone know?

• Why Google Analytics is displaying wrong landing pages?

  - by Salman

  I see all of my pages as Landing Pages in Google Analytics which cannot be true as I did not post those pages anywhere and I don't see any traffic hitting directly to that page. Also, I am using virtual page views on few buttons and I see those virtual pages as Landing pages too. For example, /click/request-a-quote 35000 views 35000 is too big a number to be ignored. Even if I ignore Virtual Pages Views, I see a lot of pages as Landing Pages that I am 100% sure that visitors ( atleast not so many users) are NOT hitting directly. Any advice, how to debug it? PS: I'm using the following code: var _gaq = _gaq || []; _gaq.push(['_setAccount', '<']); _gaq.push(['_setDomainName', 'none']); _gaq.push(['setLocalGifPath', '/images/_utm.gif']); _gaq.push(['_setAllowLinker', true]); _gaq.push(['_trackPageview','account/phase1']);

• Fixed Bid vs. T&amp;M &ndash; Take 2

  - by AjarnMark

  One of my most popular blog entries of all time is my Contracting Tips: Fixed Bid vs. T&M post from January, 2004.  This post consistently shows up in my referrers list, usually coming from a search engine.  Recently, Brent Ozar (@BrentO) wrote a great argument for why he always bills by the hour (a.k.a. Time & Materials or T&M) which itself was a response to Mark Richman’s (@mrichman) post on why he never bills by the hour (fixed bid).  Each article has good arguments, and I encourage you to read them both and choose the best approach for you. As for me, my experience parallels Brent’s and I historically have leaned toward the Time & Materials model.

• Problems using easing equations in C# XNA

  - by codinghands

  I'm having some trouble using the easing equations suggested by Robert Penner for ActionScript (http://www.robertpenner.com/easing/, and a Flash demo here) in my C# XNA game. Firstly, what is the definition of the following variables passed in as arguments to each equation? float t, float b, float c, float d I'm currently calculating the new X position of a sprite in the Update() loop, however even for the linear tween equation I'm getting some odd results. I'm using the following values: float t = gameTime.TotalGameTime.TotalMilliseconds; float d = 8000f; float b = x.Position.X; float c = (ScreenManager.Game.GraphicsDevice.Viewport.Width >> 1) - (x.Position.X + x.frameSize.X / 2); And this equation for linear easing: float val = c*t/d + b;

• Creating date based back entries for a blog and its site registration

  - by open_sourse

  So I am showing a blog to a colleague and telling him how the author has been regularly blogging for over ten years now. My colleague tells me that anyone can register a domain name and start entries from say circa 2000. When I argued that the site registration date can easily show that the registration was done recently he put forward two arguments: The author can claim that he moved from an old domain name which was registered many years ago and lapsed. So he took the data and rebuilt it in the new site. The author can buy an expired domain which was on the internet for many years. I am not sure if these ways can work to con someone to believing you have been a blogger for over a decade. But I do not have enough expertise in the topic to refute him. So I thought I would ask the wise community here at StackExchange. Can anyone give me some insight?

How do I achieve this?

• Why is better to use external JavaScript or libraries ; and is it prefered to use jquery meaning more security?

  - by shareef

  I read this article Unobtrusive JavaScript with jQuery and I noticed these points in the slide page 11 some companies strip JavaScript at the firewall some run the NoScript Firefox extension to protect themselves from common XSS and CSRF attacks many mobile devices ignore JavaScript entirely screen readers do execute JavaScript but accessibility issues mean you may not want them to I did not understand the fourth point. What does it mean? I need your comment and responses on these points. Is not using JavaScript and switching to libraries like jQuery worth it? UPDATE 1 : whats the meaning of Unobtrusive JavaScript with jQuery ? and yes it does not say we should use libraries but we should have them on external files for that reason i asked my question.

• When JDeveloper IDE doesn't render the visual editor

  - by Frank Nimphius

  Though with Oracle JDeveloper 11g the problem of the IDE not rendering JSF pages properly in the visual editor has become rare, there always is a way for the creative to break IDE functionality. A possible reason for the visual editor in JDeveloper to break is a failed dependency reference, which often is in a custom JSF PhaseListener configured in the faces-config.xml file. To avoid this from happening, surround the code in your PhaseListener class with the following statement (for example in the afterPhase method) public void afterPhase(PhaseEvent phaseEvent) {   if(!ADFContext.getCurrent().isDesigntime()){ ... listener code here ... } } The reason why the visual editor in Oracle JDeveloper fails rendering the WYSIWYG view has to do with how the live preview is created. To produce the visual display of a view, JDeveloper actually runs the ADF Faces view in JSF, which then also invokes defined PhaseListeners. With the code above, you check whether the PhaseListener code is executed at runtime or design time.If it is executed in design time, you ignore all calls to external resources that are not available at design time.

• Kubuntu 12.04: Change login screen background?

  - by drezabek

  I am having trouble changing my login screen background. I can select the default wall paper, the Kde-default one, but when ever I select my own custom wallpaper, there is no image, just a solid color. Normally, I would just ignore it, but the thing that bugs me is that this is a fresh install of Kubuntu 12.04 64bit, and the OS before this one, the one I overwrote, I had no trouble using the exact same image as the background... Settings In the System Settings application, Login Screen settings, Background tab, enable background, Under "Background", selected Picture, under options, selected Position: Scaled. Colors: Single Color. Blending: No Blending.

• I have a large number of links on every page, for design reasons I want to keep it but is it hurting my SEO

  - by Callum Rexter

  The site is http://www.centralsaddlery.co.uk We have other issues which we are tackling in terms of content etc but the question I have is: "Is my main navigation hurting us in SEO?" Its a lot of links and it's on a lot of pages. If so - what is a way to get google to ignore links below the top level. I had thought google would see that the links are hidden by default and only shown on hover but I can't verify this at all. We absolutely want to keep the menu, our customers like it and so do we - we think it is pretty usable as we have a lot of products to look at. Any advice is appreciated (and any tips for any part of the SEO are welcome too)

• Unable to install 11.10 to new OCZ Agility 3 SSD

  - by Masi

  I know the discussion here where they are not getting the same error as I. I use Lenovo Thinkpad X60. The default partition table: sd1 ext4 53.91GB, sd2 extended 1.99GB and sd5 swap 1.99GB. I get Input/output error during read on /dev/sda when trying to install from LiveCD -mode and when trying to install directly. I get the error normally at the stage of choosing time zone or very last at choosing the keyboard layout. Then there is the box with buttons: back, ignore and continue. Neither of them put the process forward so I need to cancel it. How can you install Ubuntu to SDD disk?

• How to remove non-working session entries in LightDM?

  - by Lexalt

  I recently added Cairo Dock to my GNOME Shell in 11.10. Cairo Dock is GREAT, but I'm left with one little problem that I'd like to fix: after installing Cairo Dock, LightDM includes two extraneous entries to non-working desktops. (The entries to working desktops remain unaffected, so I guess I could just ignore the extraneous entries, but...) So I'd like to remove/edit the extraneous entries in LightDM. I've looked and looked for discussions on how to do so, but haven't had much luck. Any suggestions on how to go about editing the login menu in 11.10?

• Does the EU cookie law apply to an EU site that is hosted outside of the EU?

  - by mickburkejnr

  I have been reading up about this EU cookie law, and have also had in depth conversations with my girlfriend who is a solicitor/lawyer and with colleagues while building websites. While we are now working towards implementing a way to abide by the EU law, I have thought of something which no one really knows the answer to and has caused a few arguments. It's my understanding that any website in the EU must abide by these cookie laws, which is understandable. However, say if I were to have a .co.uk or .eu domain name pointing to a website which is hosted in America for example, do I still need to abide by the EU laws even though the website is hosted outside of the EU? One person I have asked has said that because the domain name is .co.uk or .eu (a European TLD) then the website is still accountable under EU law. Another person I have asked has said because the actual website is held outside of the EU, it doesn't actually have to bother with this law.

• How do I recover a BTRFS partition that will not mount?

  - by Tony

  The installation for 12.04 kept failing, and the solution was to have the installer ignore the btrfs partition that I have previously been using for /home. Now that it's installed, I've been trying to get it to mount the btrfs partition so that I can access my 70GB of files. It won't mount, and btrfsck errors out with the following three lines: parent transid verify failed on 31302336512 wanted 62455 found 62456 parent transid verify failed on 31302336512 wanted 62455 found 62456 parent transid verify failed on 31302336512 wanted 62455 found 62456 Can someone please tell me how to get this partition working? I've read online that I can probably recover the data using btrfs-restore, but I can't find that program anywhere.

• My Oracle Support 6.3 - Knowledge Highlights

  - by JanSyss

  My Oracle Support 6.3 was released over the weekend (13-Oct-2012), and with that we released 30+ enhancements and 60+ bug fixes. Most important changes Search Suggestions are auto-correcting spelling errors, more suggestions for 'how to' type questions, enhanced usability to see the suggested additional terms. Improved Knowledge Base region on the My Oracle Support dashboard: recent searches from this region now retain the search attributions (e.g. pre-selected products or release). Search Tip: if the Knowledge Base region doesn't show up as the first region in the right column on the My Oracle Support dashboard, consider personalizing your dashboard to put it first, so that you right there for searching. Specifying the product you are researching an issue for, with optionally version and task as well, makes searches in the majority of the cases more precise. for more information, see my comments in my previous blog on the topic: https://blogs.oracle.com/supportportal/entry/mos_6_2_release Better support for searches on ORA-600 & ORA-700: no longer a difference in results between searching on 'ORA-600 [Arg1]' and 'Ora-00600: Internal Error Code, Arguments: [Arg1]'.

• Working with vectors and transformations

  - by user29163

  I am going to write an graphical 2D application that allows user to create polygons and transform them through transformation such as rotation an so on. I was hoping someone can give pro and cons arguments for the different choices I got in my mind. (Its all in Java btw!) a). Represent vectors by filling matrices with 'real' numbers. This means making a matrix datas tructure that supports multiplication, transposing etc b). Make a own vector class, such that I can make a matrix class that support those vectors.

• What are the steps taken by this GLSL code?

  - by user827992

  1 void main(void) 2 { 3 vec2 pos = mod(gl_FragCoord.xy, vec2(50.0)) - vec2(25.0); 4 float dist_squared = dot(pos, pos); 5 6 gl_FragColor = (dist_squared < 400.0) 7 ? vec4(.90, .90, .90, 1.0) 8 : vec4(.20, .20, .40, 1.0); 9 } taken from http://people.freedesktop.org/~idr/OpenGL_tutorials/03-fragment-intro.html Now, this looks really trivial and simple, but my problem is with the mod function. This function is taking 2 vec2 as inputs but is supposed to take just 2 atomic arguments according to the official documentation, also this function makes an implicit use of the floor function that only accepts, again, 1 atomic argument. Can someone explain this to me step by step and point out what I'm not getting here? It's some kind of OpenGL trick? OpenGL Math trick? in the GLSL docs i always find and explicit reference to the type accepted by the function and vec2 it's not there.

• Objects disappear when zoomed out in Unity

  - by Starkers

  Ignore the palm trees here. I have some oak-like trees when I'm zoomed in: They disappear when I zoom out: Is this normal? Is this something to do with draw distance? How can I change this so my trees don't disappear? The reason I ask is because my installation had a weird terrain glitch. If this isn't normal I'm going to reinstall right away because I'm always thinking 'is that a feature? Or a glitch'?

• What caused you to stop using UML tools on your team?

  - by jamie

  There seems to be plenty of good, free UML tools. I hear about UML tools being used by large organizations, and they seem to have plenty of advocates. However, in my career I have never seen them used beyond "dabbling". Now, I have seen many UML diagrams drawn on whiteboards, and I use them myself all the time, on paper, to think about problems. I've also seen articles such as this one claiming why developers don't use UML, but the arguments just don't land with me. Frankly, this seems like an opportunity for a start-up if one can figure out why developers really don't use them, and solve those problems. So I'm asking anyone here who has attempted to use UML tools in a team, and stopped, this question: "why did you stop?" I'm especially interested in experience from agile teams. I am looking for concrete experience, not hypothetical opinion. Thanks.
