• Collapsible menu and amount of links in a web page

  - by dstonek

  One of my pages contain three levels of a collapsible menu (JS + CSS from mycssmenu.com). There are a dozen first level items displayed to users, each one with various second level items, and finally a lot of third level items, each one containing a related link. This generates a lot of internal links (300+). Because of SEO should I change the way the collapsible menu is displayed to reduce link amount? What do you suggest? I would like to avoid users to have to open a new page just to only see what are third level items and eventually follow one of its links.

• What do you do when one think the code isn't complicated enough?

  - by Chris

  After six months of development on a project, our stakeholders have had a "gut check" and have decided that the path that we've been walking (a custom designed application framework and data access layer) is holding us (the developers) back from quickly developing the features they would like to see. After several days of debate management and the development team have decided to scrap the current incarnation and start over using ASP.net MVC, with Entity Framework as the bases of the a 'quick and dirty', lets just get it done project. In days following, our senior developer who has never worked with MVC or Entity Framework has finally gotten into a sample project and done some work. His take on ASP.net MVC, "this is not software engineering". So my question is this; what do you do, when one doesn't think the code is complicated enough?

• WUBI Install freezes on startup

  - by Benjamin

  Ok, I don't completely know of all the specifications, but installing Ubuntu 12.04.1 on my cousin's old Windows XP computer, an old Compaq from around 2004. After install via Wubi, and going through several unsuccessful install attempts, I finally get the start up screen of Ubuntu, and it freezes once you get to the pretty default wallpaper. Not even a login screen. Just instant freeze! We've left it on for about a day now and its still frozen, any help? (Please reply ASAP, he wont stop bugging me about it)

• Dual boot: Linux Grub loader does not show windows

  - by user292099

  my computer previously only had windows installed on it. Recently I decided to try Linux and opted for a dual boot so I installed Linux Mint 17 Cinnamon 64-bit on a separate hard drive within my computer. After installation my computer would directly boot to Linux upon start up and did not even show a grub screen. Using the boot-repair I was finally able to make the Grub loader show a boot list upon start up, but the Windows partition is not there. The boot-info summary is found on this link. http://paste2.org/9pIGZtDv Any help would be great Motherboard: Gigabyte z77 ud5h OS: Linux Mint 17 Cinnamon 64-bit & Windows 8.1 64-bit

• Cannot save all of the property settings for this Web Part.

  - by ybbest

  I would like to display all the items of custom content type of Animals in a SharePoint content query WebPart. After choosing the appropriate values in the web part editor and click on Save I got this error: Cannot save all of the property settings for this Web Part. There is a problem with one or more of the field values below. But when I examine all the values below , it does not flag any error information. I finally manage to locate the error flag after I expand the presentation section. I then delete the text in the Link textbox , now I can save the settings. However , I think the error message should have been more specific so that users can quickly locate the error. The worst part for this is that I did not even change anything in the presentation section, I merely configure the Source in the Query section. Well, I guess I am still new to SharePoint, I just have to get used to these generic error message ):

• Fixing a broken toolbox (In Visual Studio 2010 SP1)

  - by mbcrump

  I was recently running into a situation where every time I opened Visual Studio 2010 SP1, the following message would appear for about 60 seconds or so: "Loading toolbox content from package Microsoft.VisualStudio.IDE.Toolbox.ControlInstaller.ToolboxInstallerPackage '{2C98B35-07DA-45F1-96A3-BE55D91C8D7A}'" After finally get fed up with the issue, I started researching it and decided that I’d share the steps that I took to resolve it below: I first made a complete backup of my registry. I then removed the following key: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\Packages\{2c298b35-07da-45f1-96a3-be55d91c8d7a}] I went to the following directory: C:\Users\Your Name Here\AppData\Local\Microsoft\VisualStudio\10.0\ and created a folder called bk and moved the .tbd files to that folder (they are hidden so you will have to show all files). I then removed the .tbd files in the root directory. I then launched Visual Studio 2010 SP1 again and it recreated those files and the problem was gone. Anyways, I hope this helps someone with a similar problem. I created this blog partially for myself but it is always nice to help my fellow developer.  Thanks for reading. Subscribe to my feed

• Hello Again, San Francisco

  - by Geertjan

  From the moment I got to the airport in Amsterdam, I've been bumping into JavaOne pilgrims today. Finally got to my hotel, after a pretty good flight (and KLM provides great meals, which helps a lot), and a rather long wait at customs (serves me right for getting seat 66C in a plane with 68 rows). And, best of all, on Twitter I've been seeing a few remarks around the Duke's Choice Awards for this year. The references all point to the September - October issue of the Java Magazine, where page 24 shows the following: So, from page 24 onwards, you can read all about the above applications. What's especially cool is that three of the above are applications created on top of the NetBeans Platform! That's AgroSense (farm management software), MICE (NATO system for defense and battle-space operations), and Level One Registration Tool (UN Refugee Agency sofware for managing refugees). Congratulations to all the winners, looking forward to learning more about them all during the coming days here at the conference.

• Using fix-boot but still stuck

  - by user92498

  I have a laptop I used to use for college that was Ubuntu 10.4 /Vista / Win7. I pulled it out and proceeded to install 12.04 advanced partitioning. It was sda1 ubuntu / swap / vista / and sda5 win7. I deleted the ubuntu, swap and vista, leaving 7 alone. I'm using it now but can't get to win7. I used fix-boot several times using variations on the advanced menus. So I finally purged grub and forced grup-pc in the advanced setting of fix-boot. Here is a link to the report; http://paste.ubuntu.com/1225051/ I'm sure there is a way to edit the grub to get 7 to show as a boot choice and hope someone can point it out for me. Thanks

• Understanding how to go from a scene to what's actually rendered to screen in OpenGL?

  - by Pris

  I want something that explains step by step how, after setting up a simple scene I can go from that 'world' space, to what's finally rendered on my screen (ie, actually implement something). I need the resource to clearly show how to derive and set up both orthographic and perspective projection matrices... basically I want to thoroughly understand what's going on behind the scenes and not plug in random things without knowing what they do. I've found lots of half explanations, presentation slides, walls of text, etc that aren't really doing much for me. I have a basic understanding of linear algebra/matrix transforms, and a rough idea of what's going on when you go from model space - screen, but not enough to actually implement it in code.

• Menus don't sync in the first place

  - by Bruce Mincks

  I have been wrestling with prompts about my default key ring for months, finally made contact with Ubuntu with the right password, and find that when I try to sync evolution Ubuntu directs me to "system-preferences- " and then the road forks between the "passwords and encryption" you indicate and the "encryption and keyrings. I have no idea which version I am using, at this point. The road goes downhill from there. I would really like to synch my windows manager and Inkscape vs. ImageMagick display (circles display as semicircles). Can someone set me straight?

• Who could ask for more with LESS CSS? (Part 1 of 3&ndash;Features)

  - by ToStringTheory

  It wasn’t very long ago that I first began to get into CSS precompilers such as SASS (Syntactically Awesome Stylesheets) and LESS (The Dynamic Stylesheet Language) and I had been hooked on the idea since.  When I finally had a new project come up, I leapt at the opportunity to try out one of these languages. Introduction To be honest, I was hesitant at first to add either framework as I didn’t really know much more than what I had read on their homepages, and I didn’t like the idea of adding too much complexity to a project - I couldn’t guarantee I would be the only person to support it in the future. Thankfully, both of these languages just add things into CSS.  You don’t HAVE to know LESS or SASS to do anything, you can still do your old school CSS, and your output will be the same.  However, when you want to start doing more advanced things such as variables, mixins, and color functions, the functionality is all there for you to utilize. From what I had read, SASS has a few more features than LESS, which is why I initially tried to figure out how to incorporate it into a MVC 4 project. However, through my research, I couldn’t find a way to accomplish this without including some bit of the Ruby on Rails framework on the computer running it, and I hated the fact that I had to do that.  Besides SASS, there is little chance of me getting into the RoR framework, at least in the next couple years.  So in the end, I settled with using LESS. Features So, what can LESS (or SASS) do for you?  There are several reasons I have come to love it in the past few weeks. 1 – Constants Using LESS, you can finally declare a constant and use its value across an entire CSS file. The case that most people would be familiar with is colors.  Wanting to declare one or two color variables that comprise the theme of the site, and not have to retype out their specific hex code each time, but rather a variable name.  What’s great about this is that if you end up having to change it, you only have to change it in one place.  An important thing to note is that you aren’t limited to creating constants just for colors, but for strings and measurements as well. 2 – Inheritance This is a cool feature in my mind for simplicity and organization.  Both LESS and SASS allow you to place selectors within other selectors, and when it is compiled, the languages will break the rules out as necessary and keep the inheritance chain you created in the selectors. Example LESS Code: #header {   h1 {     font-size: 26px;     font-weight: bold;   }   p {     font-size: 12px;     a     {       text-decoration: none;       &:hover {         border-width: 1px       }     }   } } Example Compiled CSS: #header h1 {   font-size: 26px;   font-weight: bold; } #header p {   font-size: 12px; } #header p a {   text-decoration: none; } #header p a:hover {   border-width: 1px; } 3 - Mixins Mixins are where languages like this really shine.  The ability to mixin other definitions setup a parametric mixin.  There is really a lot of content in this area, so I would suggest looking at http://lesscss.org for more information.  One of the things I would suggest if you do begin to use LESS is to also grab the mixins.less file from the Twitter Bootstrap project.  This file already has a bunch of predefined mixins for things like border-radius with all of the browser specific prefixes.  This alone is of great use! 4 – Color Functions This is the last thing I wanted to point out as my final post in this series will be utilizing these functions in a more drawn out manner.  Both LESS and SASS provide functions for getting information from a color (R,G,B,H,S,L).  Using these, it is easy to define a primary color, and then darken or lighten it a little for your needs.  Example: Example LESS Code: @base-color: #111; @red:        #842210; #footer {   color: (@base-color + #003300);   border-left:  2px;   border-right: 2px;   border-color: desaturate(@red, 10%); } Example Compiled CSS: #footer {    color: #114411;    border-left:  2px;    border-right: 2px;    border-color: #7d2717; } I have found that these can be very useful and powerful when constructing a site theme. Conclusion I came across LESS and SASS when looking for the best way to implement some type of CSS variables for colors, because I hated having to do a Find and Replace in all of the files using the colors, and in some instances, you couldn’t just find/replace because of the color choices interfering with other colors (color to replace of #000, yet come colors existed like #0002bc).  So in many cases I would end up having to do a Find and manually check each one. In my next post, I am going to cover how I’ve come to set up these items and the structure for the items in the project, as well as the conventions that I have come to start using.  In the final post in the series, I will cover a neat little side project I built in LESS dealing with colors!

  I installed Ubuntu 12.04 on a Presario R 3000. The Wireless card was not detected (firmware missing).

• Why CoffeeScript is an issue

  - by Renso

  Other than some obvious concerns, my main concern is support in the open source community. "anon" from the CoffeeScript team sent this to me after I requested input from the team to concerns I raised and wanted to get others' take on it:"Thanks for confirming that only idiots willingly program in Java and C#"or the following from the same person:"Oh and finally, you should definitely create jShort. Even though I know you will fail before you even start, I would love to laugh at your attempts and it would be perfect for you since you ride the short bus. "This kind of comment reflects badly on the CoffeeScript team and hence not an option for us as a company to consider. Another example of why some open-source community projects get no traction.

• SSL on multiple directories

  - by Shredder

  I have a website that is http, but has a port set up for https for a specific directory that is for the shopping cart. Now I'd like to use our SSL on a different directory in the same site as well. How can I go about configuring that? I have tried looking into all of the config files as well as the docs and cannot figure it out. I tried setting this in httpd.config as well <VirtualHost 127.0.0.1:[ssl port]> #also tried *:[ssl port] and [actual IP]:[ssl port] ServerAdmin [email protected] DocumentRoot "C:/path/sslNeededDir" ServerName www.example.com </VirtualHost> hoping that it would cause pages in this directory to use ssl port and become https, but that didn't do anything. Any help is greatly appreciated. Update: This finally got migrated over. I'm still looking for a solid answer on this. If anyone could help me, it would be greatly appreciated.

• Partner case - ISE (Germany) - IDS brings light into Investment Controlling with Exadata

  - by Javier Puerta

  (Original post in German: IDS bringt mit Exadata Licht ins Investmentcontrolling) "The amount of data that IDS GmbH (Analysis and Reporting Services) has to cope with daily, is enormous: at the subsidiary of Allianz SE all the services are around Investment Controlling.The company needed an extensible data warehouse solution in which all the data could be merged together, harmonized and enriched. Finally IDS decided for Exadata to be as optimal solution, specifically the Oracle Exadata Database Machine. The implementation was carried out jointly with the Oracle Platinum Partner ISE, who took over the technical and advisory support part and will be IDS´ preffered consultant in any further Exadata development.

• Shutdown issues on my Dell XPS M1530

  - by CppLearner

  On my Dell XPS M1530 lapttop, I am facing issues with shut-down option after upgrading to 12.04 LTS from 11.10. Sometimes it shutdowns "cleanly". But other times everything goes down but I can still see the power LED glowing (even after removing the power cord). If I keep it like that laptop temperature increases. So finally I opt for "hard shut-down" (i.e. pressing the power button on). Any thoughts what is happening here?.

• Is this a reliable method of parsing glGetShaderInfoLog()?

  - by m4ttbush

  I want to get a list of errors and their line numbers so I can display the error information differently from how it's formatted in the error string and also to show the line in the output. It looks easy enough to just parse the result of glGetShaderInfoLog(), look for ERROR:, then read the next number up to :, and then the next, and finally the error description up to the next newline. However, the OpenGL docs say: Application developers should not expect different OpenGL implementations to produce identical information logs. This makes me worry that my code may behave incorrectly on different systems. I don't need them to be identical, I just need them to follow the same format. So is there a better way to get a list of errors with the line number separate, is it safe to assume that they'll always follow the "ERROR: 0:123:" format, or is there simply no reliable way to do this?

• What methodology to use for planning/developing a Language conversion project?

  - by user 123

  I am trying to help my friend by creating a part of his on-going project. What I'm going to do is create a Java parser to break up the Java code into operators, parameters etc to build XML representation. Next I want to create a code generator to convert the parsed java code to XML conforming to the schema I've created. Finally I want to use an XML style-sheet to transform the XML into another programming language type. Basically I just wanted some advice on which methodology/model I should use for planning and developing this project. Is there some benefit to using Agile etc for instance?

• 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?

• installing 12.04 failing

  - by Steve

  I just downloaded 12.04 burned it to a cd, and booted to into it on my last built computer. It loads a purple screen, then goes to a dos looking screen with a blinking cursor then loads the ubuntu loader. The lights go from red to white and finally they all turn red. This is when the entire screen goes to noise and just hangs. Seems like a hardware issue but I can successfully boot into a non genuine windows7 that I'm looking to replace. I'm not sure what to try, so any help would be appreciated. Thanks.
