• DualLayout OpenSourceFood demo site installation instructions

  - by svdoever

  We released DualLayout which enables advanced web design with the power of SharePoint. DualLayout and a demo site can be downloaded from the DualLayout product page. This blogpost contains detailed instructions on installing the demo site. The demo site is based on the site http://opensourcefood.com. The demo site requires internet access because it still links to pages and resources of the real site. Execute the following steps to install the demo site: Copy the OpenSourceFoodDemo.zip file to your SharePoint Server 2010 Make sure that the zip file in “unblocked”, otherwise files are assumed from other computer (right-click on zip file, press “Unblock” button if available) Unzip the OpenSourceFoodDemo.zip to a folder of your choice (c:\OpenSourceFoodDemo) Open the SharePoint  Start->Microsoft SharePoint 2010 Products->SharePoint 2010 Management Shell Change directory to the unzip folder (cd c:\OpenSourceFoodDemo) Start install script: .\InstallDemoSite.ps1 Answer the questions, default values in most cases ok. A little guidance: Question: Give credentials for the account that will be used for the application pool Answer: use for example same account as used for the application pool of your SharePoint site (lookup in IIS Manager) Question: Give credentials for the account that will be used for the application pool Answer: Use same account you are currently logged in with The demo site is made available through a backup and restore. The SharePoint Server 2010 installation must be patched to a level equal or higher to the update level on the SharePoint Server used to create the backup. If you get errors with respect to restore check http://technet.microsoft.com/en-us/sharepoint/ff800847.aspx for downloading the latest cumulative update.

• Installing httpssl module on a running NGINX server

  - by Rob

  Hi, New to NGINX, we inherited a project that runs Django/FCGI/NGINX on a hosted RHEL box. A requirement has come in that the site now needs to have ssl enabled. Client was pretty sure the person who had built the site had made it so they could use ssl. I backed up the conf file, added the server block for the ssl instance and tried to reload. Reload failed because it didn't recognize the ssl in this line: ssl on; Not an NGINX expert, but the David Caruso in me tells me that the server (sunglasses on) is not secure. I know that you need to configure NGINX at install with this module. If this didn't happen, how hard/risky is it to reconfigure a running nginx box with this module given that we didn't configure it in the first place.

• When is the default storage rule not really the default storage rule?

  - by Kevin Smith

  In 11g WebCenter Content (WCC) introduced dispersion rules in the vault and weblayout directory paths to better distribute content across the directories. The dispersion rule was based on dRevClassID. The only problem with this is that dRevClassID did not remain the same when you copied content from one WCC instance to another using Archiver like in a contribution-consumption scenario. This could cause problems because the web-viewable path would not be the same between the contribution and consumption instances. In the PS5 (11.1.1.6.0) release of WCC they addressed this by configuring the File Store Provider (FSP) so that all new content would use a storage rule with a dispersion rule based on dDocName, which would stay the same when content was copied to another WCC instance. To support migration from older versions of WCC they left the default storage rule unchanged and created a new storage rule called DispByContentId and made that the default storage rule for all new content. I only stumbled upon this a while back when I was trying to change the FSP configuration so that all content used a webless storage rule. I changed the default storage rule, restarted WCC, and checked in a new content item. To my surprise the new content was not created as webless. I struggled with this for a while until I noticed there were multiple storage rules defined in the FSP configuration. When I looked at the default value for the xStorageRule field in Configuration Manager, sure enough it was no longer default, but was now DispByContentId. Once I updated the DispByContentId storage rule to webless and restarted WCC all my new content was now created using the webless storage rule, just like I wanted. I noticed when I was creating this blog post that the default storage rule is also listed on the File Store Provider Information page, but I guess I didn't see that when I originally did this.

• Can you install Ubuntu Server in a Windows PC VM on Windows 7?

  - by Lance Fisher

  I am running Windows 7 64-bit. I've installed Windows Virtual PC and Windows XP Mode successfully. Next, I downloaded Ubuntu Server 9.04 32-bit. I created a new virtual machine with a dynamically expanding .vhd, loaded the Ubuntu .iso, and booted the machine. I successfully made it through the install, but when the machine reboots, I get a segmentation fault. Here is a screenshot. Has anyone successfully installed Ubuntu on Windows Virtual PC?

• Mysql Master-ColdMaster

  - by enedebe

  I explain my case: I'm at Amazon AWS and I want to be fault tolerant on a entire region failure. My basic problem is to have the db in sync with 2 regions. My options: Master-Master (high lag) Hand made sync every 5 minutes Master-ColdMaster?! (copy on the fly but Master won't wait the other region commit) In my system we could afford loosing a piece of data (we're not a bank) the last inserts in the db, but we could not afford more than 10 minutes of downtime. The database is small and the level of inserts is low, and I wouldn't affect the normal usage waiting other region commit. Is the 3 solution posible? And the most important, once the primary fail how we can detect and change the rol between master-coldmaster -- coldmaster-master ? Is there any clean-mode to restore between failure? Thank's!

• How to calculate Bradford Factors with Excel 2007?

  - by pnuts

  Bradford Factors are used by some to measure the significance of absenteeism and are computed for each individual as S squared * D where S is the number of spells (continuous periods of absence) and D is the sum of the days. The calculation is often made over a rolling 52 weeks. Commercial HR software often has the facility to calculate these factors but a Google search indicates quite a lot of interest without any free solutions. Using units of half a day and including any non-working days in each spell, how does one calculate the factors using Excel 2007?

• One site being on a subdirectory of another. Does google count this against you?

  - by Mick

  I have created two similar websites (relating to monetary systems). So far, one appears to be loved by Google and the other hated. I'm struggling to work out why. This is a mystery to me because both sites were created by me with the same design philosophy, both in pure html. Both are packed to the rafters with references to, and information about, their respective subjects. One issue I'm worried may be the cause is to do with the location of the sites. I got a web hosting package from hostmonster.com for the successful one, but less liked one is just an "add-on" which sits on a subdirectory of the successful one. I wonder if Google somehow detects this and treats it as a less significant website? EDIT: Just to clarify, even though one site is an add-on that sits on a subdirectory of the other, the URL is arranged to look like it is a root. I.e. the unpopular site can be accessed directly with a simple www.myunpopularsite.com name, without specifying any subdirectory. EDIT: Just in case its important... say the popular site is called pop.com and the unpopular one unpop.com. In the webspace I've purchased, there is a directory called public_html. This is where I put the index.htm and all the other files of my popular site. When I purchased the add-on unpop.com. I made a subdirectory of public_html called unpop. It is within this "public_html\unpop\" that I place the index.htm and all the other files of my unpopular site. Typing www.unpop.com into the address bar of a browser links directly to the contents of "public_html\unpop\" and the user is not aware that this site is sitting on a subdirectory of another site. BUT if you type "www.pop.com/unpop" into the address bar of a browser you DO see the unpopular site.

• Why google return soft 404 when I redirect on signup page?

  - by Hettomei

  Since one month, I've got an increased "soft 404" reported by google webmaster tools but work well for users. I made some fix but can't figure out how to solve it. Configuration (maybe useless): I have a website built with rails 3.1 Authentication is handled by the gem Devise Problem: On this page http://en.bemyboat.com/yacht-charter/9965-sailboat-beneteau-oceanis-43 when you click on "Ask a Boat request" (a simple form, in GET to : http://en.bemyboat.com/boat_requests/new/9965) you are redirected with the http status 302 to sign in, and then sent back to the new page if successfully sign in. Google tells me that the link on "ask a boat request" returns a soft 404. I can't make this form in "POST" (which will solve the problem) because we need to automatically redirect user to the good page after sign in. (the Gem Devise memorize the "get" link) To simplify, the question is: how to protect a private page with authentication, reached with a simple "get" and not to be penalized by google with "soft 404". Thank you. PS : this website suffer a lot about english translation... please don't care.

• Should I use an interface when methods are only similar?

  - by Joshua Harris

  I was posed with the idea of creating an object that checks if a point will collide with a line: public class PointAndLineSegmentCollisionDetector { public void Collides(Point p, LineSegment s) { // ... } } This made me think that if I decided to create a Box object, then I would need a PointAndBoxCollisionDetector and a LineSegmentAndBoxCollisionDetector. I might even realize that I should have a BoxAndBoxCollisionDetector and a LineSegmentAndLineSegmentCollisionDetector. And, when I add new objects that can collide I would need to add even more of these. But, they all have a Collides method, so everything I learned about abstraction is telling me, "Make an interface." public interface CollisionDetector { public void Collides(Spatial s1, Spatial s2); } But now I have a function that only detects some abstract class or interface that is used by Point, LineSegment, Box, etc.. So if I did this then each implementation would have to to a type check to make sure that the types are the appropriate type because the collision algorithm is different for each different type match up. Another solution could be this: public class CollisionDetector { public void Collides(Point p, LineSegment s) { ... } public void Collides(LineSegment s, Box b) { ... } public void Collides(Point p, Box b) { ... } // ... } But, this could end up being a huge class that seems unwieldy, although it would have simplicity in that it is only a bunch of Collide methods. This is similar to C#'s Convert class. Which is nice because it is large, but it is simple to understand how it works. This seems to be the better solution, but I thought I should open it for discussion as a wiki to get other opinions.

• Gain Access to a Facebook account using an email I no longer have access to

  Trying to regain access to a Facebook account I haven't used in years which was set up while I was in school with my school email account, which no longer exists. Don't know the password to the Facebook account. I went here and made a request. Got an email within minutes and and replied to it. That was over week ago. Anyone gone through this before? How long did it take? Any way to expedite the process? Any alternate way to contact Facebook team and get some help with this?

• What exactly do I have to pay attention for when choosing Windows Hosting Provider?

  - by user850010

  This is my first time choosing a hosting company. It is for a web site made in asp.net mvc3. So I was thinking choosing a provider would be easy since I found this page http://www.microsoft.com/web/Hosting/Home which contains hosting offers. Now hours later, I am still searching. The reason is that as soon as I start investigating about particular company, something stands out that I do not like. Here are some examples what I noticed when checking various companies in more detail: Company "about us" page is lacking in information about their company. Few of them had just general description what they do and nothing else, while some others had information like company name but had no address. Checking company name in Business Registry Searches gave no results. Two of the companies I checked had both company name and address but I was unable to find them in the registry. Putting company domain into Google gave mostly results from that domain or web hosting review sites but not much else. I am assuming that good companies should have search results from other sites too. Low Alexa Traffic Rank. There was one company which had a site that looked very professional but their alexa traffic ranking was like 2 million. Are there any other factors I should pay attention to when choosing a hosting company? Do I have legitimate concerns or am I just too paranoid?

• Resolution stuck in 640x480 in grub, 11.04 and 12.04

  - by user89797

  I have three operating systems on my machine, Windows 7x64, Ubuntu 11.10 and 12.04 both x64 as well. All three were running at full resolution for my monitor, as well as in the Grub 1.99 boot screen. After booting into Windows, I rebooted my machine and found my Grub resolution was suddenly 640x480. Booting into both versions of Ubuntu, I find myself stuck at that resolution as well. I made no driver changes recently, and hadn't even booted into the 11.10 build in a month or more. I've gone through both proprietary Nvidia driver options for my card (GeForce 9800GT) as well as the open source drivers in 12.04 to no avail. I can't figure out what could have caused this change in both versions of Ubuntu and Grub simultaneously. Windows 7 is unaffected so I think that safely rules out hardware failure. EDIT Ok, so I couldn't boot an graphical live disks, I tried ubuntu 12.04 i386 and x64 as well as 12.10 beta x64 and all of them would flash the initial logo, go to a blank screen with a flashing cursor in the upper left and then my display would die. I managed to boot 12.04 server and get into recovery. I reinstalled grub and went into recovery mode for my 12.04 build. If I boot in safe graphics mode I can get 1280x768, but as soon as I reboot it's broken again. I've tried reinstalling the nvidia drivers and that leaves me with a system stuck at max 640x480. None of these changes have had any impact on the 11.10 build, which is still stuck at 640x480 Given that I can push a somewhat higher resolution in 12.04, and full resolution in windows 7 I'm pretty convinced it's not an issue of my monitor failing. It must be something to do with the graphics drivers. I can't figure out what could be the issue though. I'm especially perplexed that I can't boot any live images

• What You Said: How You Sync and Organize Your Bookmarks

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your favorite techniques for synchronizing and organizing your browser bookmarks. Now we’re back to highlight the most popular techniques, tricks, and services. By far and away, Xmarks was the most frequently mentioned service. For the unfamiliar, Xmarks is a bookmark syncing service that is packed with features. Not only does Xmarks sync bookmarks between browsers and/or computers it also supports iOS, Android, and BlackBerry (mobile integration requires an upgrade to the premium account). In addition to syncing the bookmarks it also integrates with your search results so you can see how other Xmarks users have ranked sites within your search results. Steve-O-Rama highlights one of the many benefits of Xmarks: Xmarks seems to do the job for me. I’ve got a handful of machines, each with three or four browsers; over the years, I’ve accumulated thousands of bookmarks, stretching across many areas of interest. Trying to keep them all straight had been quite a struggle until Xmarks came along. I freaked out when the company was acquired by LastPass, but was subsequently relieved when they continued the free service. Xmarks has a very nice web interface to access, export, search, organize, and do many other things with your bookmarks. In this way, even if I’m on the go, I can access every bookmark I’ve made. Even so, I still make occasional local backups, directly from the browsers to a network folder. Delicious bookmarks, another veteran of the bookmark syncing services, had a fair number of supporters among the HTG readership.

• Working Abroad Advice Needed

  - by RBA

  Hi, First of all, Happy New Year everybody! I wish you for 2011 all the best! For several years I was thinking about to work abroad, and I want to make this step(to work in a/several foreign countries, for several years). I am a Software Developer with a Bachelor of Engineering in Computer Science, with a +4 years of experience in Delphi(and small working experience in other programming languages). Until now I've applied at aprox. 100 positions over the world, and I've been contacted by 4-5 hiring managers. Our technical discussions went good, but then we reached at working visa 'problem'. I don't have legal/health problems, but I don't poses a working permit in other countries except Romania. I've been reading several forums concerning the working visas (here I take out working visa for US or other 'hard to get visa' countries), and there are several steps which companies must do (so I can take out the bureaucracy problem) to make the papers. Concerning the cost of a visa, this goes up to one medium salary from that country(in most of the cases). I've been working for the last years with different clients, from a wide variety of countries, and I don't believe I will have problems with integration in a foreign country So, the problem is that the market don't need Delphi Developers (there is a small amount of open positions on the recruiting sites), and I should start learning other programming language(all the time is better to know other programming languages - but to master it, requires some time) with a higher market 'rank' (Java/C#/etc), OR the problem is only concerning the working visa, and maybe the reticence of the employer to foreign possible candidates? I'm asking this especially for those users who made this step in their life or they want to make it in the future. Best regards,

• Prefer class members or passing arguments between internal methods?

  - by geoffjentry

  Suppose within the private portion of a class there is a value which is utilized by multiple private methods. Do people prefer having this defined as a member variable for the class or passing it as an argument to each of the methods - and why? On one hand I could see an argument to be made that reducing state (ie member variables) in a class is generally a good thing, although if the same value is being repeatedly used throughout a class' methods it seems like that would be an ideal candidate for representation as state for the class to make the code visibly cleaner if nothing else. Edit: To clarify some of the comments/questions that were raised, I'm not talking about constants and this isn't relating to any particular case rather just a hypothetical that I was talking to some other people about. Ignoring the OOP angle for a moment, the particular use case that I had in mind was the following (assume pass by reference just to make the pseudocode cleaner) int x doSomething(x) doAnotherThing(x) doYetAnotherThing(x) doSomethingElse(x) So what I mean is that there's some variable that is common between multiple functions - in the case I had in mind it was due to chaining of smaller functions. In an OOP system, if these were all methods of a class (say due to refactoring via extracting methods from a large method), that variable could be passed around them all or it could be a class member.

• What stops HTML5 and JS apps to perform as good as native apps?

  - by Amogh Talpallikar

  From what I understand, HTML is a mark-up language, so is the content of XAML, XIB and whatever Android uses and other native UI development frameworks. JavaScript is a programming language used along with it to handle client side scripting which will include things like event handling, client side validations and anything else C#,Java,Objective-C or C++ do in various such frameworks. There are MVC/MVVM patterns available in form frameworks like Sencha's, Angular etc. We have localStorage in form of both sqlite and key-value store as other frameworks have and you have API specification for almost everything that it missing. Whenever a native UI frameworks has to render UI , it has to parse a similar the markup and render the UI. Question break-down What stops from doing the same in HTML and JS itself ? Instead of having a web-control or browser as a layer in between why can't HTML(along with CSS) and JS be made to perform the same way ? Even if there is a layer,so does .net runtime and JVM are in other cases where C++,C are not being used. So Lets take the case of Android, like Dalvik, why Can't Chromium be another option(along with dalvik and NDK) where HTML does what android markup does and JavaScript is used to do what Java does ? So the Question is, Even if current implementations aren't as good, but theoretically is it possible to get HTML5 based applications to work as other native apps specially on mobile ?

• I accidentally hid my Gnome Panel

  I got a new tablet pc, and in attempt to hide the empathy mail icon, accidentally made the entire panel dissappear. (The one at the top that has applications/places/system, and battery life/network connections etc). I don't believe I killed it, because alt+f2, then gnome-panel does not bring it back. I've tried alt+ctrl+backspace to reset gnome, that didn't bring it back. It must just be some setting like 'hide' or something... Any tips to get it back? Thanks.

• AMD Radeon 7900 series: setting up 3 monitors

  - by Nilzone-

  I have an AMD Radeon 7900 series, which should support up to 6 screens. I'm having problems getting my third one working. Im running windows 8, and have installed all the latest AMD drivers. My screens are: Samusng syncmaster S27D391HS Samusng syncmaster S24B350H Samusng syncmaster S24B350H The first 24" monitor I use HDMI to DVI cable. The second 24" I use VGA to DVI cable. Lastly, for the 27" I use HDMI cable. The result is, no matter what I do, I never get more than two screens on simultaneously. I have also tried getting a DisplayPort to HDMI cable to use for the 27", but Im not sure if it was passive or active (didn't say on the box, nor did I ask). So my question is: is an active displayport to HDMI the solution, or is there someting else Im overlooking? (I have read similar posts on this subject, but I use a slightly different combo of cables. That is why I made a post of my own as well)

• Make an object slide around an obstacle

  - by Isaiah

  I have path areas set up in a game I'm making for canvas/html5 and have got it working to keep the player within these areas. I have a function isOut(boundary, x, y) that returns true if the point is outside the boundary. What I do is check only the new position x/y separately with the corresponding old position x/y. Then if each one is out I assign them the past value from the frame before. The old positions are kept in a variable from a closure I made. like this: opos = [x,y];//old position npos = [x,y];//new position if(isOut(bound, npos[0], opos[1])){ npos[0] = opos[0]; //assign it the old x position } if(isOut(bound, opos[0], npos[1])){ npos[1] = opos[1]; //assign it the old y position } It looks nice and works good at certain angles, but if your boundary has diagonal regions it results in jittery motion. What's happening is the y pos exits the area while x doesn't and continues pushing the player to the side, once it has moved the player to the side a bit the player can move forward and then the y exits again and the whole process repeats. Anyone know how I may be able to achieve a smoother slide? I have access to the player's velocity vector, the angle, and the speed(when used with the angle). I can move the play with either angle/speed or x/yvelocities as I've built in backups to translate one to the other if either have been altered manually.

• How can I change the color of the pane separator for my Ambiance theme modification?

  - by WarriorIng64

  I am currently messing around with Ambiance, trying to give Nautilus a dark sidebar (because I think it looks much better that way, especially with the current look having the dark-colored breadcrumbs clashing horribly with the light-colored sidebar). I have zero experience and knowledge of how to create GTK+ themes, and I couldn't find any documentation online, so I just made a copy of the folder for Ambiance under /usr/share/themes, renamed it "Ambiance Dark Sidebar" and just started messing with color values. As shown below, I found the value in nautilus.css needed to be tweaked to create the dark sidebar, but there is still one part that stubbornly stays light gray. This is the pane separator, and I want to change it so it matches the rest better (marked in red). Does anyone know what I need to do to change the color of this part so it matches the rest of the sidebar better? I already know from seeing themes like Adwaita Dark that this should be possible, but even after poking around in that I didn't find anything that seemed to help. Here are the contents of the files I modified in the theme folder Ambiance Dark Sidebar, stored alongside Ambiance in /usr/share/themes: index.theme gtk-3.0/apps/nautilus.css

• Java Applet Tower Defence Game needs tweeking

  - by Ephiras

  Hello :) i have made a tower defence Game for my computer science class as one of my major projects, but have encountered some rather fatal roadblocks. here they are creating a menu screen (class Menu) that can set the total number of enimies, the max number of towers, starting money and the map. i tried creating a constructor in my Main class that sets all the values to whatever the Menu class passes in. I want the Menu screen to close after a difficulty has been selected and the main class to begin. Another problem i would really like some help with is instead of having to write entire arrays i would like to create a small segment of code that runs through an entire picture and sets up an array based on that pixels color.this way i can have multiple levels just dragged into a level folder and have the program read through them. users can even create their own. so a 1 if its yellow, a two if blue and a 3 if purple, then everything else = 0; you can download all the classes and code uif you'd like here sorry about having to redirect you but i wasn't sure how to efficently add a code spoiler. help is greatly appreciated

• Reinventing the Wheel, why should I?

  - by Mercfh

  So I have this problem, it may be my OCD (i have OCD it's not severe.....but It makes me very..lets say specific about certain things, programming being one of them) or it may be the fact that I graduated college and still feel "meh" at programming. Reading This made me think "OH thats me!" but thats not really my main problem. My big problem is....anytime im using a high level language/API/etc. I always think to myself that im not really "programming". I know I know...it sounds stupid. But Like I feel like....if i can't figure out how to do it at the lowest level then Im not really "understanding" it. I do this for just about every new technology I learn. I look at the lowest level and try to understand it. Sometimes I do.....most of the time I don't, I mean i've only really been programming for 4 years (at college, if you even call it programming.....our university's program was "meh"). For instance I do a little bit of embedded programming (with the Atmel AVR 8bits/Arduino stuff). And I can't bring myself to use the C compiler, even though it's 8 million times easier than using assembly......it's stupid I know... Anyone else feel like this, I think it's just my OCD that makes me feel this way....but has anyone else ever felt like they need to go down to the lowest level of the language to even be satisfied with using it? I apologize for the very very odd question, but I think it really hinders me in getting deep seeded into a programming language and making a real application of my own. (it's silly I know)

• GNOME changes to KDE on Maverick

  - by Pit

  Hi, I recently made a clean/fresh install of Ubuntu 10.10 an experienced the problem that the theme changes from Gnome to KDE and back randomly and partly. Sometimes after starting my computer I will have a KDE theme. If I then open the Appearance Preferences ( System - Preferences - Appearance ) some applications and the main-menu as well as menu of applications (only upper two centimetres of a application window) will change back to Gnome only by opening it, not changing anything nor saving. I did not choose KDE at any time, nor did I do any changes to the appearance prior to the first occurrence of this bug. On a second computer I updated from 10.04 to 10.10 and experienced the same bug. On this computer I did however change the layout of the minimize;maximise;close buttons by following How do I move the Window buttons from left to right?. But I don't see how this could provoke the bug, especially as it occurs on a second computer. Will doing updates I saw that there a quite a lot of KDE packages being downloaded. Do I even need those if I don't want to use KDE?

• Looking for someone to point me in the right direction. I want to learn how to use hosted servers

  - by Leisure

  TL;DR: I want a Java program to run on a server, I want the server to forward a particular port from external to internal IP, I want store a few files on the server. Guides please. So I made a hack job Java program that acts as a server for my android application. It stores data in text files and HTML files, uploads them via FTP to my webhost, and manages socket connections (using port forwarding) with any phones connected. Right now I'm running it on NetBeans on my home computer. I know that it will probably slow down or crash once about 50 phones are connected at once. Is there any way I can run this program on a server with a high bandwidth? Can someone please find me a guide for that? I'm noob and don't know where to start looking. I seriously don't know anything about renting or using servers - I need a nice guide, and recommendations. My requirements for the server: Can handle about 2k socket connections at once Can run my Java code and store my txt files Can give me a port and an IP address so TCP/IP clients can be connected My budget: $50 CAD per month. Please someone set my ship sailing in the right direction, I really don't know where to look for resources.
