  - by Sahil Malik

  SharePoint 2010 Training: more information You know that ECB Menu in SharePoint 2007? Well in SharePoint 2010 you can very easily move it around on any column you wish. What you do is, open the view in SharePoint Designer, then you click on the field you wish to see the ECB menu in, then you will see a little floatie button with this on it ">", then, you click on that floatie, and it shows a little popup with 2 checkboxes in it. "Common xsl:value-of Tasks"- Show List Item Menu- Show Link To Item You check the "Show List Item Menu" checkbox, and off you go - now the ECB menu is available on the other column. Enjoy!

• How do I rename a mounted Truecrypt volume?

  - by invert

  When I mount the Truecrypt file on my USB drive it shows up as truecrypt1. The volume is FAT, using mtools to rename a volume label involves e2label /dev/sdbx, however truecrypt1 does not map to a physical partition. fdisk -l does not show the volume partition (only the physical USB device), and df -h lists the volume path as /dev/mapper/truecrypt1. Finally, using the Nautilus 'Rename' context action, gives the error: "Sorry, could not rename "truecrypt1" to "towel": Operation not supported by backend". Apparently this can be done in Win, but how can I rename this volume in Ubuntu? As Nicolas said, specifying the mount point names the partition the same. The truecrypt GUI does not remember the mount point I set, so I specify the mount points in a script which I placed in my main menu. #!/bin/bash gksudo truecrypt /media/usbdrive/encryptedfile /media/securedata/

• One dimensional cutting algorithm with minimum waste

  - by jm666

  Can anybody point me to some resources about "cutting algorithm"? The problem: have rods with length of L meters, e.g. 6 m need cut smaller pieces of different lengths, e.g. need: 4 x 1.2m 8 x 0,9m etc... (many other lengths and counts) How to determine the optimal cutting, what will produce the minimum wasted material? I'm capable write an perl program, but haven't any idea about the algorithm. (if here is already some CPAN module what can help, would be nice). Alternatively, if someone can point me to some "spreadsheet" solution, or to anything what helps. Ps: in addition, need care about the "cutting line width" too, whats means than from the 6m long rod is impossible to cut 6 x 1m, because the cutting itself takes "3mm" width, so it is possible cut only 5 x 1m and the last piece will be only 98.5 cm (1m minus 5 x 3mm cut-width) ;(.

• Can't boot Ubuntu 12.10 graphics problem

  - by Frantumn

  I can't boot since installing Ubuntu 12.10 When I try to run Ubuntu My computer never gets to the Ubuntu screen with the loading dots. I tried to run in recovery mode with safe graphics (failsafex) When I do this a message pops up saying "the system is running in low graphics mode", If I click okay I am asked what would I like to do and am given four options. I tried running low graphics for one session and then a message appears with a progress bar and says standby one minute while the display restarts. The progress bar never moves and if I click okay the whole process just restarts. I Don't know what to do from here I can't get into the OS. I'm not sure whether the problem is related to compatibility with my laptop monitor or my graphic card nvidia360m I had to install using a safe graphics mode. To learn about how I installed see this link. This link also has information on my computer hardware. Can't install Ubuntu since 10.10 ----UPDATE--- I was able to get into a desktop environment By installing Nvidia-current however it is messy. I have a screen and I am able to see my desktop however there is no unity bar and none of the keyboard controls work. I can right click and create a folder on the desktop and then I can see inside that folder in a traditional browser window. There is still no top menu or unity bar. When I boot normally I don't get into the desktop environment and I get this message in tty 'GPU lockup switching to software FBCON' Okay, I've played around with tips the pages from comments. I've been able to consistantly get into a safemode desktop environment using the xorg & nouveau drivers. I've tried switching between the 5 different options in the Additional Drivers tab in Software Sources. The nVidia (proprietary, tested) driver gets beyond the GPU lockup on a normal boot and actually gets into a Desktop. The issue is then that there is no Unity bar, or top screen menu bar and the resolution is very low. I've tried switching to the (prop, tested) driver and then reinstalling Unity and Ubuntu-Desktop but that didn't work either.

• Microsoft Unveils New Logo

  Indeed, with those four familiar colored squares - set in a bigger square rather than standing on a point in a diamond - Microsoft's new corporate logo seems almost inevitable. As you'd expect, the company's name makes up part of the logo, but instead of the thick italic letters it has used for the past two and a half decades, it's in a more standard, lighter font. Jeff Hansen, Microsoft's general manager of brand strategy, notes that the point of the new logo is to signal the heritage but also signal the future - a newness and a freshness. It's very fitting when you consider just how many...

• Why appending to a list in Scala should have O(n) time complexity?

  - by Jubbat

  I am learning Scala at the moment and I just read that the execution time of the append operation for a list (:+) grows linearly with the size of the list. Appending to a list seems like a pretty common operation. Why should the idiomatic way to do this be prepending the components and then reversing the list? It can't also be a design failure as implementation could be changed at any point. From my point of view, both prepending and appending should be O(1). Is there any legitimate reason for this?

• Ubuntu 12.04 - Swiching Multiple Windows from a Program

  - by Judy Liu

  I'm having problem switching multiple windows from a same program. For example, if I have 2 windows opened for firefox at the same time and I wanted to switch from one another, it used to display a 2 small grid preview for each session when I click on the icon. However, that function doesn't seem to be working on my ubuntu 12.04 now. It doesn't response when I click on the firefox (or other application) icon in the sidebar. Does anyone know how to fix this? By the way, I know ALT-TAB can switch windows too, but it's hard to switch if I have 7 pdf documents opened at the same time. So I really wish to have this feature fixed. Thanks in advance.

• Should I use nodindex, follow or rel canonical?

  - by webmasters

  I have a site that lists offers, promotions from other websites. Since the offers expire rather quickly I don't save them into my database. I see no point in having a page from 2010 about 30% discount on a certain brand of shoes which isn't availabe anymore. A visitor enters my website; He clicks on the "shoes" category; http://www.mysite.com/shoes/ Here he sees 20 available promotions from different online stores. He clicks on a promotion and gets to a page like this: http://www.mysite.com/shoes/promotions/prada Questions: I use the template promotions.php and list all the promotions. /promotions/prada/ /promotions/otherbrand/ .... What I do is use "noindex, follow" for the links. Is that a good idea? Or should I use rel="canonical" for the promotion page? How do you advise me to handle this from the SEO point of view?

• Dependency Injection Confusion

  - by James

  I think I have a decent grasp of what Dependency Inversion principle (DIP) is, my confusion is more around dependency injection. My understanding is the whole point of DI is to decouple parts of an application, to allow changes in one part without effecting another, assuming the interface does not change. For examples sake, we have this public class MyClass(IMyInterface interface) { public MyClass { interface.DoSomething(); } } public interface IMyInterface { void DoSomething(); } How is this var iocContainer = new UnityContainer(); iocContainer.Resolve<MyClass>(); better practice than doing this //if multiple implementations are possible, could use a factory here. IMyInterface interface = new InterfaceImplementation(); var myClass = new MyClass(interface); It may be I am missing a very important point, but I am failing to see what is gained. I am aware that using an IOC container I can easily handle an objects life cycle, which is a +1 but I don't think that is core to what IOC is about.

• Why is this by passing the SUDO password?

  - by John Isaacks

  I have a bash script I am using to automate a SVN checkout. The contents of the file were: #!/bin/bash cd /var/www-cake sudo svn checkout file:///usr/local/svn/bash_repo/repo/ Then when I double click the file it would ask me what to do, I would click the button "Run In Terminal" and then a terminal would pop up and ask me for the SUDO password. I would enter it, the script would execute and the terminal would close. I wanted to give some sort of indication that the script ran successfully so I edited my file to look like: #!/bin/bash cd /var/www-cake sudo svn checkout file:///usr/local/svn/bash_repo/repo/ echo "Head revision has been pushed to live server" I expected the terminal to now stay open and tell me the message afterwards. To my surprise it now opens and immediately closes. The script does execute and I no longer have to put in the SUDO password. Is this right? I do not understand why this is happening, seems like a security issue.

  - by max

  I just installed 12.04 and when clicking mailto: links Thunderbird opens. I want Gmail to open in the browser that the mailto: link is clicked. So if I am in Firefox and click a mailto: link a new FF tab opens with Gmailloaded. And if I am in Chrome and click a mailto: link then a new Chrome tab opens up with Gmail loaded. Is there a way to do this via some script? Or would I need to set this in some system settings?

  - by Przemek Jedlikowski

  I just want to install Ubuntu 13.10 alongside Windows 7 HP on my EeePC 1215N. I can't do it when Windows 7 is booted up (wubi.exe hasn't got that option), so I booted it from USB key. Everything's loaded, I double-click Install Ubuntu. I click 'Next ', then I choose that I want to install Ubuntu alongside Windows 7. And the machine restarts. Not resets. Restarts. X server's killed immediately, I can see the console only. What do I have to do now?

• Why do HDFS clusters have only a single NameNode?

  - by grautur

  I'm trying to understand better how Hadoop works, and I'm reading The NameNode is a Single Point of Failure for the HDFS Cluster. HDFS is not currently a High Availability system. When the NameNode goes down, the file system goes offline. There is an optional SecondaryNameNode that can be hosted on a separate machine. It only creates checkpoints of the namespace by merging the edits file into the fsimage file and does not provide any real redundancy. Hadoop 0.21+ has a BackupNameNode that is part of a plan to have an HA name service, but it needs active contributions from the people who want it (i.e. you) to make it Highly Available. from http://wiki.apache.org/hadoop/NameNode So why is the NameNode a single point of failure? What is bad or difficult about having a complete duplicate of the NameNode running as well?

• OpenGL Get Rotated X and Y of quad

  - by matejkramny

  I am developing a game in 2D using LWJGL library. So far I have a rotating box. I have done basic Rectangle collision, but it doesn't work for rotated rectangles. Does OpenGL have a function that returns the vertices of rotated rectangle? Or is there another way of doing this using trigonometry? I had researched how to do this and everything I found was using some matrix that I don't understand so I am asking if there is another way of doing this. For clarification, I am trying to find out the true (rotated) X,Y of each point of the rectangle. Let's say, the first point of a rectangle (top,left) has x=10 y=10.. Width and height is 100 pixels. When I rotate the rectangle using glRotatef() the x and y stay the same. The rotation is happening inside OpenGL. I need to extract the x,y of the rectangle so I can detect collisions properly.

• PageRank sharing between domains?!

  - by Senthil

  I own three domains, say.. example.com, example.in, example.co.in I have bought the .in and .co.in TLDs only to protect the brand. But I have this question: If I make the other two also point to my hosting so that regardless of which one the user types, they are taken to the same website, will the PageRank be split into three and will each domain have one third the actual PR value? What should I do with the other two domains? Where should I point them to, if I don't intend to use them at all (i.e., what should I give in place of the ns1.myprovider.com, ns2.myprovider.com etc..?)

• Has test driven development (TDD) actually benefited a real world project?

  - by James

  I am not new to coding. I have been coding (seriously) for over 15 years now. I have always had some testing for my code. However, over the last few months I have been learning test driven design/development (TDD) using Ruby on Rails. So far, I'm not seeing the benefit. I see some benefit to writing tests for some things, but very few. And while I like the idea of writing the test first, I find I spend substantially more time trying to debug my tests to get them to say what I really mean than I do debugging actual code. This is probably because the test code is often substantially more complicated than the code it tests. I hope this is just inexperience with the available tools (RSpec in this case). I must say though, at this point, the level of frustration mixed with the disappointing lack of performance is beyond unacceptable. So far, the only value I'm seeing from TDD is a growing library of RSpec files that serve as templates for other projects/files. Which is not much more useful, maybe less useful, than the actual project code files. In reading the available literature, I notice that TDD seems to be a massive time sink up front, but pays off in the end. I'm just wondering, are there any real world examples? Does this massive frustration ever pay off in the real world? I really hope I did not miss this question somewhere else on here. I searched, but all the questions/answers are several years old at this point. It was a rare occasion when I found a developer who would say anything bad about TDD, which is why I have spent as much time on this as I have. However, I noticed that nobody seems to point to specific real-world examples. I did read one answer that said the guy debugging the code in 2011 would thank you for have a complete unit testing suite (I think that comment was made in 2008). So, I'm just wondering, after all these years, do we finally have any examples showing the payoff is real? Has anybody actually inherited or gone back to code that was designed/developed with TDD and has a complete set of unit tests and actually felt a payoff? Or did you find that you were spending so much time trying to figure out what the test was testing (and why it was important) that you just tossed out the whole mess and dug into the code?

• System freeze after opening Wi-Fi menu can boot into the machine and use Internet in recovery mode

  - by Michael

  So right now sitting in front of my Alienware area 51 desktop. It has a Broadcom Netlink BCM 5784M gigabit ethernet PCI E card. Most of the time able to get through the login screen and to the main screen if I click on the wireless settings on the top right-hand corner the system immediately freezes the cursor does not move at all keyboards are unresponsive. I was doing some quick Google searching and I found a suggestion to boot into recovery mode I did this and did a apt-get Distribution update which ran successfully installed then I rebooted into the regular system same thing I'm pretty sure it's the network card because even if I don't click the settings if a network related dialog opens such as disconnection or connection the system again immediately freezes. I'm running Ubuntu 13.04 ** update 1 ** Just was able to use my system for a little bit however when I went into Firefox and hit the web it again froze so obviously a driver problem but I'm not sure how to get drivers for Broadcom which apparently according to the description on stack-overflow is terrible Any ideas? Sorry for lack of punctuation on an ipad.

• "A hard disk may be failing" , but no additional info via gdu-notification-deamon (suggestions?)

  - by blunders

  Got this message after logging in: A hard disk may be failing One or more hard disk report health problems. Click the icon to get more information. On WUBI and 10.04, there was no icon to click, and clicking on made the message go away. After rebooting, the message did not display again. I've got everything on all my hard drives in duplicate, so not super worried about a disk failure, though I am wondering why the message had no info on which disk it thought had problems. Suggestions?

• Even More Steroids for JEditorPane

  - by Geertjan

  Got some help from Ralph today and now the JEditorPane is as I want it, e.g., code folds are now supported once you click in the JEditorPane, though there are still some side effects, since this is not how anyone anticipated NetBeans editor APIs being used. But, so far, the side effects (e.g., now the hyperlinks work, but they open a new JavaScript file when you click on one of them, instead of jumping within the JEditorPane itself) are not so terrible. Error checking is also done now, which wasn't there before, i.e., red underlines and error annotations in the right margin. And maybe it's my imagination, but the editor feels a lot snappier, e.g., in code completion, than before. I've checked in the changes, they're all in this file: http://java.net/projects/nb-api-samples/sources/api-samples/content/versions/7.3/misc/CMSBackOffice2/CMSBackOffice2-editor/src/main/java/com/mycompany/cmsbackoffice2editor/GeneralTab.java

• How can I change my "Desktop bar"?

  - by d_Joke

  The problem: In Gnome 3.4 when I click the main menu, it's white. The text of the menu is also white. Original text: I have a problem. When I installed the new version of Gnome (3.4) the "Desktop bar" (I'm sorry, I don't know what's the real name of that bar, but is the bar on the top on Ubuntu 11.10) every time I click on the username icon, or the battery, etc., the menu comes on gray or white and the letters are white. I know maybe this is a stupid question but it annoys me. Besides, my username doest not appear on the login screen. I tried to reset my settings, I delete gnome, and check the Unsettings and CompizConfig but the problem is still there. Maybe I miss something on the process of looking on any configuration tool but I don't think so... Sorry if the question is something basic or even stupid but I'm new on Ubuntu and I'm experimenting whit it.

• Implement Fast Inverse Square Root in Javascript?

  - by BBz

  The Fast Inverse Square Root from Quake III seems to use a floating-point trick. As I understand, floating-point representation can have some different implementations. So is it possible to implement the Fast Inverse Square Root in Javascript? Would it return the same result? float Q_rsqrt(float number) { long i; float x2, y; const float threehalfs = 1.5F; x2 = number * 0.5F; y = number; i = * ( long * ) &y; i = 0x5f3759df - ( i >> 1 ); y = * ( float * ) &i; y = y * ( threehalfs - ( x2 * y * y ) ); return y; }

• Do search engines rank internal redirects negatively?

  - by siverd

  A client is in the late stages (code complete) of a website redesign and unfortunately hasn't implemented 301 redirects to point high traffic pages to the new URL's. As I understand it our only option at this point is to create redirects within the CMS. Our CMS allows us to do this: www.mysite.com/category/current-page.html will redirect to www.mysite.com/new-category-name/new-page.html The site now uses custom logic on our 404 page to check this list of redirects and if one exists forwards the user to the new-page.html I understand that using 301 redirects would be the correct way to maintain our page rank but I think that would require a code change which isn't possible. Question How will search engines respond to this? Will they wait until the redirect happens and allow us to keep our page rank (authority, trust, etc) or will they see the 404 page and down-rank us? Worst case...will they make our new-page.html start from a rank of "0"? Thanks for your help.

• rotate player based off of joystick

  - by pengume

  Hey everyone I have this game that i am making in android and I have a touch screen joystick that moves the player around based on the joysticks position. I cant figure out how to also get the player to rotate at the same angle of the joystick. so when the joystick is to the left the players bitmap is rotated to the left as well. Maybe someone here has some sample code I could look at here is the joysticks class that I am using. `public class GameControls implements OnTouchListener { public float initx = DroidzActivity.screenWidth - 45; //255; // 320 og 425 public float inity = DroidzActivity.screenHeight - 45;//425; // 480 og 267 public Point _touchingPoint = new Point( DroidzActivity.screenWidth - 45, DroidzActivity.screenHeight - 45); public Point _pointerPosition = new Point(DroidzActivity.screenWidth - 100, DroidzActivity.screenHeight - 100); // ogx 220 ogy 150 private Boolean _dragging = false; private boolean attackMode = false; @Override public boolean onTouch(View v, MotionEvent event) { update(event); return true; } private MotionEvent lastEvent; public boolean ControlDragged; private static double angle; public void update(MotionEvent event) { if (event == null && lastEvent == null) { return; } else if (event == null && lastEvent != null) { event = lastEvent; } else { lastEvent = event; } // drag drop if (event.getAction() == MotionEvent.ACTION_DOWN) { if ((int) event.getX() > 0 && (int) event.getX() < 50 && (int) event.getY() > DroidzActivity.screenHeight - 160 && (int) event.getY() < DroidzActivity.screenHeight - 0) { setAttackMode(true); } else { _dragging = true; } } else if (event.getAction() == MotionEvent.ACTION_UP) { if(isAttackMode()){ setAttackMode(false); } _dragging = false; } if (_dragging) { ControlDragged = true; // get the pos _touchingPoint.x = (int) event.getX(); _touchingPoint.y = (int) event.getY(); // Log.d("GameControls", "x = " + _touchingPoint.x + " y = " //+ _touchingPoint.y); // bound to a box if (_touchingPoint.x < DroidzActivity.screenWidth - 75) { // og 400 _touchingPoint.x = DroidzActivity.screenWidth - 75; } if (_touchingPoint.x > DroidzActivity.screenWidth - 15) {// og 450 _touchingPoint.x = DroidzActivity.screenWidth - 15; } if (_touchingPoint.y < DroidzActivity.screenHeight - 75) {// og 240 _touchingPoint.y = DroidzActivity.screenHeight - 75; } if (_touchingPoint.y > DroidzActivity.screenHeight - 15) {// og 290 _touchingPoint.y = DroidzActivity.screenHeight - 15; } // get the angle setAngle(Math.atan2(_touchingPoint.y - inity, _touchingPoint.x - initx) / (Math.PI / 180)); // Move the ninja in proportion to how far // the joystick is dragged from its center _pointerPosition.y += Math.sin(getAngle() * (Math.PI / 180)) * (_touchingPoint.x / 70); // og 180 70 _pointerPosition.x += Math.cos(getAngle() * (Math.PI / 180)) * (_touchingPoint.x / 70); // make the pointer go thru if (_pointerPosition.x > DroidzActivity.screenWidth) { _pointerPosition.x = 0; } if (_pointerPosition.x < 0) { _pointerPosition.x = DroidzActivity.screenWidth; } if (_pointerPosition.y > DroidzActivity.screenHeight) { _pointerPosition.y = 0; } if (_pointerPosition.y < 0) { _pointerPosition.y = DroidzActivity.screenHeight; } } else if (!_dragging) { ControlDragged = false; // Snap back to center when the joystick is released _touchingPoint.x = (int) initx; _touchingPoint.y = (int) inity; // shaft.alpha = 0; } } public void setAttackMode(boolean attackMode) { this.attackMode = attackMode; } public boolean isAttackMode() { return attackMode; } public void setAngle(double angle) { this.angle = angle; } public static double getAngle() { return angle; } }` I should also note that the player has animations based on when he is moving or attacking. EDIT: I got the angle and am rotating the sprite around in the correct angle however it rotates on the wrong spot. My sprite is one giant bitmap that gets cut into four pieces and only one shown at a time to animate walking. here is the code I am using to rotate him right now. ` public void draw(Canvas canvas,int pointerX, int pointerY) { Matrix m; if (setRotation){ // canvas.save(); m = new Matrix(); m.reset(); // spriteWidth and spriteHeight are for just the current frame showed //m.setTranslate(spriteWidth / 2, spriteHeight / 2); //get and set rotation for ninja based off of joystick m.preRotate((float) GameControls.getRotation()); //create the rotated bitmap flipedSprite = Bitmap.createBitmap(bitmap , 0, 0,bitmap.getWidth(),bitmap.getHeight() , m, true); //set new bitmap to rotated ninja setBitmap(flipedSprite); setRotation = false; // canvas.restore(); Log.d("Ninja View", "angle of rotation= " +(float) GameControls.getRotation()); } ` And then the draw method // create the destination rectangle for the ninjas current animation frame // pointerX and pointerY are from the joystick moving the ninja around destRect = new Rect(pointerX, pointerY, pointerX + spriteWidth, pointerY + spriteHeight); canvas.drawBitmap(bitmap, getSourceRect(), destRect, null);
