• Disable alt + tab moving windows by itself

  - by Lie Ryan

  Whenever I press Alt + Tab , Unity moves the window I'm switching to so that the whole window is inside the screen. This behavior is excruciatingly annoying because I often move a window (usually text editors) partially outside the current screen so I can view another window below it (usually a browser). Every time I Alt + Tab back to the text editor, I'm getting an unnecessary virtual screen switch, and Unity is rearranging the windows behind my back. For instance, here is a browser and text editor on Virtual Screen 1 (top left), note that the text editor is partially outside the current screen: Then I Alt-Tab to the browser (or clicked on it): Next, I Alt + Tab again to get back to the text editor, but Alt-Tab switched me to Virtual Screen 4 (bottom right) because a larger percentage of the text editor window is on virtual screen 4 than in virtual screen 1; and the browser is no longer in the screen. Also note that the text editor window moves from being on the bottom-right to the top-left, which is very disorienting as I can no longer keep track of where any of my windows are since they all keep moving around by themselves.. How do I disable this behavior? I don't want to have any virtual screen switch when Alt + Tab , especially since Alt + Tab does not list windows that is completely not in the current virtual screen anyway.

• How to Uninstall Internet Explorer 10 in Windows 8

  - by Taylor Gibb

  We previously explained why so many geeks hate Internet Explorer, and even though Internet Explorer 9 and 10 are greatly improved, and on par with the competition, we’re still going to explain how to uninstall it from Windows 8 if you should want to do so. Uninstalling Internet Explorer 10 Press the Win + R keyboard combination and type appwiz.cpl into the run box, then hit enter. When the Programs and Features window opens, you are going to want to click on the “Turn Windows features on or off” hyperlink on the left hand side. Next, find Internet Explore and uncheck it. You will then be given a warning, you can just click yes to continue. Now click on the OK button, and then reboot your machine. Once you machine has restarted, you will see that Internet Explorer is no longer in the taskbar You should also notice that the Metro version of Internet Explorer has also been removed. That’s all there is to it.

• how do I make my Dualshock 3 gamepad work in Ubuntu 14.04?

  - by user290527

  When my desktop computer was running Ubuntu 12.04, my PS3 controllers would work with USB. I didn't need to do any special setup. I could just plug it in before I start SuperTuxKart and it would recognize it. I can also do this on my laptop (still running 12.04). Since I gave my desktop a fresh install of Ubuntu 14.04, the controller would never work. I have played with some installed software that I found when looking for information. Here is what I get with xboxdrv: liam@Liam-CustomDesktop:~$ sudo xboxdrv --detach-kernel-driver xboxdrv 0.8.5 - http://pingus.seul.org/~grumbel/xboxdrv/ Copyright © 2008-2011 Ingo Ruhnke <[email protected]> Licensed under GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html> This program comes with ABSOLUTELY NO WARRANTY. This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details. Controller: PLAYSTATION(R)3 Controller Vendor/Product: 054c:0268 USB Path: 003:012 Controller Type: Playstation 3 USB Your Xbox/Xbox360 controller should now be available as: /dev/input/js0 /dev/input/event16 Press Ctrl-c to quit, use '--silent' to suppress the event output So the existence of this controller is acknowledged at on my computer. But it never works for input. In my old installation, I didn't even need to get software like xboxdrv for it to work. I have never tried bluetooth on either computer, but I don't think I even have that on my desktop. So now, how do I make my gamepad work in Ubuntu 14.04?

• how to move the camera behind a model with the same angle? in XNA

  I meet are having difficulty in moving my camera behind an object in a 3D world. I would create two view mode. 1: for fps (first person). 2nd: external view behind the character (second person). I searched the net some example but it does not work in my project.

• Virtualbox shared folder mount from fstab fails; works once bootup is complete

  - by Ben

  I've got Ubuntu 13.10 installed in Virtualbox 4.3. The host machine is Windows. I have a couple of Virtualbox shared folders being mounted by /etc/fstab. Until recently this setup worked just fine, but after upgrading from Ubuntu 13.04 and Virtualbox 4.2 (at essentially the same time) the fstab mounting stopped working. I get the following error during boot: An error occurred while mounting /home/benme/Documents. keys:Press S to skip mounting or M for manual recovery Pressing M for manual recovery and then trying to mount manually also fails: root@benme-vb:~# cd /home/benme root@benme-vb:/home/benme# mount Documents /sbin/mount.vboxsf: mounting failed with the error: No such device But if I instead skip mounting during boot, wait for Unity to start and then mount manually in a shell, everything works fine: benme-vb ~ % ls Documents benme-vb ~ % sudo mount Documents [sudo] password for benme: benme-vb ~ % ls Documents # actual file list omitted Note that when I mount manually I'm letting mount take all the options from /etc/fstab, and it works. This suggests to me that it's some sort of timing issue, where Virtualbox isn't "ready" to provide the shared file mounts at the point /etc/fstab mounts are run during bootup. Here's the fstab line, just for completeness: Documents /home/benme/Documents vboxsf uid=benme,gid=benme,dmode=774,fmode=664 0 0 Is there something I can do about this from the Ubuntu side? Or does anyone happen to know more about this from the Virtualbox angle? I've found an old report on the Virtualbox bug-tracker with identical symptoms, but in that case the user had updated Virtualbox without updating their guest additions and resolving that fixed the problem; this isn't happening here, I've definitely got the 4.3 guest additions installed.

• how can I fix error: hd0 out of disk?

  - by rux

  I am running Ubuntu 12.04 on a netbook - Acer AS 1410. After a download session, I restarted the computer and it said: error: hd0 out of disk. Press any key to continue... I pressed everything, but it's just frozen there. Any idea what's wrong with it and what I can do to fix it? I haven't been able to run my computer at all since it's frozen like that. Help please! I booted the live cd and ran sudo fdisk -lu into terminal, and here's what it gave me: Disk /dev/sda: 60.0 GB, 60022480896 bytes 255 heads, 63 sectors/track, 7297 cylinders, total 117231408 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x9a696263 Device Boot Start End Blocks Id System /dev/sda3 2048 117229567 58613760 5 Extended /dev/sda5 * 71647232 109039615 18696192 83 Linux /dev/sda6 109041664 117229567 4093952 82 Linux swap / Solaris /dev/sda7 4096 71645183 35820544 83 Linux Partition table entries are not in disk order I am somewhat of a beginner in this, so don't know what this means. any ideas?

• New Cloud Security Book: Securing the Cloud by Vic Winkler

  - by user12608550

  It's rare that I read a technical book straight through; I usually read key chapters and save the rest for later reference. But Winkler's book, written by an accomplished and highly experienced security professional, was worth a complete read, cover to cover. Of the recently published cloud security books, such as... Cloud Security and Privacy: An Enterprise Perspective on Risks and Compliance, by Tim Mather, Subra Kumaraswamy, and Shahed Latif; O'Reilly Media Inc, 2009; Cloud Computing: Implementation, Management, and Security, by John Rittenhouse and James Ransome; CRC Press 2010; Cloud Security: A Comprehensive Guide to Secure Cloud Computing, by Ronald Krutz and Russell Vines; Wiley Publishing Inc, 2010 ...Securing the Cloud is the most useful and informative about all aspects of cloud security. Clearly, through his experience, the author has thought through many practical issues of securing large, virtualized IT installations. His Chapter 6 on Best Practices and Chapter 9 with its valuable checklists are worth the price of the book. If you are among the many new cloud computing professionals, Securing the Cloud is an essential reference for your work.

• Java Not Recognized As Default Application

  - by John

  I just installed java according to this article, and 'java -version' displays java version "1.7.0_07" Java(TM) SE Runtime Environment (build 1.7.0_07-b10) Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode) 'update-alternatives --config java' returns this: There are 2 choices for the alternative java (providing /usr/bin/java). Selection Path Priority Status ------------------------------------------------------------ 0 /usr/bin/gij-4.6 1046 auto mode 1 /usr/bin/gij-4.6 1046 manual mode * 2 /usr/local/java/jdk1.7.0_07/bin/java 1 manual mode Press enter to keep the current choice[*], or type selection number: with update-alternatives --config javac (or javaws) returning similarly. however java isn't listed in the default applications menu when I click on a .jar file and go to "open with application". I tried to install java this way, and on the update-alternatives part of the command returned me: /etc/alternatives/[java,javac,javaws] is dangling, it will be updated with best choice I just confirmed that I can use java, as 'java -jar file.jar' does work. Just figured that I'd mention it, don't know why I didn't before, but when I right click on a .jar file, java 7 run-time isn't even listed there, it seems that the file-manager isn't recognizing it as a program, but it is there, and it does work...

• removed ati proprietary driver, tried to hibernate, destroyed ubuntu installation. help?

  - by Niklas

  I totally ruined my Ubuntu 10.10 Desktop x64 installation today. I've never been able to hibernate or suspend (not with my laptop, server or htpc), not even through this guide. So I read a post here on askubuntu.com that said that the proprietary drivers may be in the way for it to work. Therefore I removed my ATI-drivers, rebooted, then tried to hibernate the system. I got some error about "blk_something_something didn't work, resubmitting1". So I turned off the computer and then tried booting up. I see the ubuntu splash but after that I'm greeted with this screen: The upper dot is the mouse pointer since I can move it with the mouse (I have ubuntu set to login automatically). I don't know how this happened. What can I do to fix this? I'm getting seriously irritated over how buggy ubuntu is, why doesn't even suspend/hibernate work (remember that I have 3 different systems where it fails)? So what is the next step? I want to get into cli mode and reinstall the driver but since I'm relatively new to ubuntu I don't know how to get into a terminal without logging in first. And if I press shift during boot I can't get into grub either and try something from there. Please come with all suggestions you can think of! Thank you very much! edit: Can I use ubuntu on a usb to insert the driver I need - if that is the problem?

• How to use the Nautilus search option

  - by Luis Alvarado

  In Nautilus if I press CTRL+F I get a search box that helps me search in the current directory and sub directories for specific names, but what if I want to: Find ALL files (including files without extensions) Find a file without an extension (Without the dot symbol or without any other name/extension separator) Find a file with/without a special character Find all files that start/not start with a character Find all files that end/not end with a character Find all files that start/no start with a character but end/not end with a character Find only files/folders Find files with specific text in them Find files with less/more/equal than/to X size Find files modified/created in X date All of this searches in the Nautilus search box I mentioned before. I ask this since the KDE's search is much better in this and gives pretty good freedom in searching for virtually anything, so I might not be learning how to use the Nautilus search option correctly. Note that I am talking about the first search done since some of this options show AFTER a search is done so the user can narrow it down more by doing a more specific search inside the Search results (for the first search). I am asking here how to do any of the search options I mentioned above in the first search.

• What resources are there for creating a dedicated NES emulator box?

  - by normalocity

  Where do I start, and what communities should I get involved in, in order to achieve the following? Ideally, I'd like to have a box that does the following (doesn't have to do this out of the box, I'm just looking to be able to achieve these goals through configs and necessary dependencies): Either bypasses login, or auto login Auto-start FCEUX with options that will (a) automatically start a ROM of my choosing, and (b) go into full-screen mode. You can assume that before I get that far, I've already configured the input devices and video options. I'd like to create (or install, if it exists) a full-screen app that takes a list of ROMs, allows me to select one with a gamepad/arcade stick, and press a button to open that game Be able to map a button on a gamepad/arcade stick to the "Power off" or exit function of the emulator, such that it will take me back to the ROM selection screen. I've already successfully installed FCEUX and tested it with an arcade stick I own, so I'm not looking for an emulator installer guide. I don't know if the ROM selector app exists already, but I'm a Java developer, and could probably create one (so long as it's not too difficult to support controllers - I was thinking of using Slick2D for this - a gaming library that I'm already pretty familiar with). The goal would be a dedicated box that I have connected to my TV. I power it on. It boots up and starts the ROM selection app, which passes the proper parameters to FCEUX (or another emulator that I might switch to at a later time), and I'm ready to go. Basically an NES emulator as a real, living room console. Also, as far as mapping a controller button to functions in the app, well, I've also played around with hardware, and it would be pretty trivial for me to modify a gamepad to trigger key presses. I just don't want to go to that length if it's not necessary.

• Oracle in Romania - 1: Brand new office, "Greenest in Bucharest"

  - by Steve Walker

  The importance of Romania within Oracle's global operations was underlined the other day as a marvellous new office building was opened at Floreasca Park in Bucharest.  The importance of the new facility was further underlined by presence of Oracle President Safra Catz, who participated in the opening ceremony. Seen here opening the building alongside Oracle Romania country leader Sorin Mindrutescu, Safra Catz said, "Our presence in Bucharest is significant and the work our teams are doing here is hugely valuable to our company and to our customers and partners. Our expansion in Bucharest signals our success in the region and commitment to making a positive contribution to the Romanian economy." The office itself looks very impressive, as the photos above show.  But more importantly, it is a cutting edge "green" office building in Bucharest, offering modern, environmentally friendly solutions such as a geo-thermal pump for heating and cooling, eco-friendly and chemical free materials used in walls and floors, a complex shading system, a bio diversity garden, and water and electricity saving equipment throughout the building. Floreasca Park is styled "the greenest office building in Bucharest" and its environmental credentials are laid out in full in a comprehensive infographic. Finally, Oracle's commitment to its Romanian operation was recognised as the company is proud to have been voted the most desired employer in Romania in surveys conducted by Catalyst Solutions and Brainspotting Consultancy. So, here's to the success of the Romanian operation, an important part of Oracle's global business and further testament to the importance of EMEA's contribution to the company's success.

• Odd Android touch event problem

  - by user22241

  Overview When testing my game I came across a bizarre problem with my touch controls. Note this isn't related to multi-touch as I completely removed my ACTION_POINTER_UP and ACTION_POINTER_DOWN along with my ACTION_MOVE code. So I'm simply working with ACTION_UP and ACTION_DOWN now and still get the problem. The problem I have a left and right button on the left of the screen and a jump button on the right. Everything works as it should but if I touch a large area of my hand (the fleshy part at the base of the thumb for instance) onto the screen, then release it and then press one of my arrows, the sprite moves in that direction for a few seconds, and then ACTION_UP is mysteriously triggered. The sprite stops and then if I release my finger and re-apply it to an arrow, the same thing happens. This goes on and on and eventually (randomly??) stops and everything work OK again. Test device & OS Google Nexus 10 Tablet running Jellybean 4.2.2 Code //Action upon which to switch actionMask = event.getActionMasked(); //Pointer Index of the currently touching pointer pointerIndex = event.getActionIndex(); //Number of pointers (for multi-touch) pointerCount = event.getPointerCount(); //ID of the pointer currently being processed (Multitouch) pointerID = event.getPointerId(pointerIndex); switch (actionMask){ //Primary pointer down case MotionEvent.ACTION_DOWN: { //if pressing left button then set moving left if (isLeftPressed(event.getX(), event.getY())){ renderer.setSpriteLeft(); } //if pressing right button then set moving right else if (isRightPressed(event.getX(), event.getY())){ renderer.setSpriteRight(); } //if pressing jump button then set sprite jumping else if (isJumpPressed(event.getX(),event.getY())){ renderer.setSpriteState('j', true); } break; }//End of case //Primary pointer up case MotionEvent.ACTION_UP:{ //When finger leaves the screen, stop sprite's horizontal movement renderer.setSpriteStopped(); break; }

• Disk failure is imminent Laptop Hard drive ~5 months old

  - by Drew

  There's another post about this, but I don't have enough 'points' to say anything on that thread. So I'll start my own ... with more details! My computer still boots, but gnome domain reports problems with HDD smart. This has been confirmed in the bios as it makes me press f1 to boot up now. I tried running HDD disk check in the bios, but it fails running the tests. As in, running the tests failed not that the tests themselves indicated a failed drive.

• In the days of modern computing, in 'typical business apps' - why does performance matter?

  - by Prog

  This may seem like an odd question to some of you. I'm a hobbyist Java programmer. I have developed several games, an AI program that creates music, another program for painting, and similar stuff. This is to tell you that I have an experience in programming, but not in professional development of business applications. I see a lot of talk on this site about performance. People often debate what would be the most efficient algorithm in C# to perform a task, or why Python is slow and Java is faster, etc. What I'm trying to understand is: why does this matter? There are specific areas of computing where I see why performance matters: games, where tens of thousands of computations are happening every second in a constant-update loop, or low level systems which other programs rely on, such as OSs and VMs, etc. But for the normal, typical high-level business app, why does performance matter? I can understand why it used to matter, decades ago. Computers were much slower and had much less memory, so you had to think carefully about these things. But today, we have so much memory to spare and computers are so fast: does it actually matter if a particular Java algorithm is O(n^2)? Will it actually make a difference for the end users of this typical business app? When you press a GUI button in a typical business app, and behind the scenes it invokes an O(n^2) algorithm, in these days of modern computing - do you actually feel the inefficiency? My question is split in two: In practice, today does performance matter in a typical normal business program? If it does, please give me real-world examples of places in such an application, where performance and optimizations are important.

• Full screen blackout using allegro in codeblocks

  - by Armando Ortiz

  I'm very interested in game programming and I'm taking my first steps alone. So I installed allegro. Although Dev-C++ didn't work, Code::Blocks compiled successfully. I started out with this basic program: #include <allegro.h> int main(){ allegro_init(); install_keyboard(); set_gfx_mode( GFX_AUTODETECT, 640, 480, 0, 0); readkey(); return 0; } END_OF_MAIN(); The problem comes in when I try to run it. It opens the little window as always, but rapidly blacks out my whole screen. I press any key and it takes me back to the little window telling me that it finished, which means the program worked. But I try any other program with allegro, like: #include <allegro.h> int x = 10; int y = 10; int main(){ allegro_init(); install_keyboard(); set_gfx_mode( GFX_AUTODETECT, 640, 480, 0, 0); while ( !key[KEY_ESC] ){ clear_keybuf(); acquire_screen(); textout_ex( screen, font, " ", x, y, makecol( 0, 0, 0), makecol( 0, 0, 0) ); if (key[KEY_UP]) --y; else if (key[KEY_DOWN]) ++y; else if (key[KEY_RIGHT]) ++x; else if (key[KEY_LEFT]) --x; textout_ex( screen, font, "@", x, y, makecol( 255, 0, 0), makecol( 0, 0, 0) ); release_screen(); rest(50); } return 0; } END_OF_MAIN(); And the same thing happens over and over again! Is there something I'm doing wrong?

• Improve Customer Experience with Real-Time Scheduling

  Recently, my husband rearranged his busy work schedule so that he could stay home an entire afternoon to wait for the alarm company to reset the password to our alarm system, only to discover at the end of the afternoon that the field service rep wasn’t going to be able to make the appointment after all. And, the company asked him to reschedule and block off time for another afternoon. Needless to say, my husband wasn’t happy with that experience. Unfortunately, customer experiences like this happen every day. As a business, you can’t afford these types of encounters. It’s too easy for your customers to turn to one of your competitors once they’ve reached the point of frustration. Customer experience and customer loyalty are more important than ever. So how can you prevent something like this from occurring? With the newly available Siebel Field Service Integration with Oracle Real-Time Scheduler, your service organization can: Create cost-optimized plans and schedules to improve operating efficiencies Deliver more accurate ETA’s and shorten appointment windows Minimize the impact of in-day events such as delays on site, sickness, poor weather conditions, and vehicle breakdowns Rather than requiring them to wait for an entire afternoon, imagine asking customers to be available for only an hour. And being able to commit to that time by working around unforeseen events and understanding the impact of delays or re-routings before they become customer issues. What would your customer experience and customer satisfaction be like then?

• Why is my root filesystem always scanned at boot?

  - by luri

  I always have a pause at boot saying my filesystems are being checked (with a "press C to cancel" note, too). Actually (seeing boot.log) I think it's the / fs, which is located at /dev/sdb5 Several questions altoghether, here (hope this does not break any rule): Is this normal? Can I (or even should I) prevent this anyhow? According to boot.log (below) the fs does not seem to be 'clean', or, at least, it's in an state or condition that makes fsck always can it for errors for a while (just a few seconds). How can I fix it? Edit: This is my boot.log: fsck desde util-linux-ng 2.17.2 udevd[515]: can not read '/etc/udev/rules.d/z80_user.rules' /dev/sdb5: 249045/32841728 ficheros (0.3% no contiguos), 20488485/131338752 bloques init: ureadahead-other main process (1111) terminated with status 4 init: ureadahead-other main process (1116) terminated with status 4 Password: * Starting AppArmor profiles [160G Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox [154G[ OK ] * Setting sensors limits [160G [154G[ OK ] And this is dumpe2fs results for the filesystem being checked (well, the relevant part of the log): Filesystem volume name: <none> Last mounted on: / Filesystem UUID: 42509bf9-f3e6-460a-8947-ec0f5c1fbcc8 Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery extent flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize Filesystem flags: signed_directory_hash Default mount options: (none) Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 32841728 Block count: 131338752 Reserved block count: 6566937 Free blocks: 110850356 Free inodes: 32592701 First block: 0 Block size: 4096 Fragment size: 4096 Reserved GDT blocks: 992 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 8192 Inode blocks per group: 512 Flex block group size: 16 Filesystem created: Fri Dec 10 19:44:15 2010 Last mount time: Mon Feb 14 17:00:02 2011 Last write time: Mon Feb 14 16:59:45 2011 Mount count: 1 Maximum mount count: 33 Last checked: Mon Feb 14 16:59:45 2011 Check interval: 15552000 (6 months) Next check after: Sat Aug 13 17:59:45 2011 Lifetime writes: 331 GB Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 256 Required extra isize: 28 Desired extra isize: 28 Journal inode: 8 First orphan inode: 28049496 Default directory hash: half_md4 Directory Hash Seed: d3d24459-514b-4413-b840-e970b766095b Journal backup: inode blocks Journal features: journal_incompat_revoke Tamaño de fichero de transacciones: 128M Journal length: 32768 Journal sequence: 0x0005e0c4 Journal start: 1 This is the relevant (at least I think this is the fs being checked) line in fstab: #Entry for /dev/sdb5 : UUID=42509bf9-f3e6-460a-8947-ec0f5c1fbcc8 / ext4 errors=remount-ro 0 1

• Two equal items in alternatives list

  - by Red Planet

  I want to have two JDKs. The first one was installed a long time ago to /usr/lib/jvm/java-7-oracle/. I installed the second version and executed following commands to add it to alternatives: red-planet@laptop:~$ sudo update-alternatives --install "/usr/bin/java" "java" "/opt/java_1.6.0_35/bin/java" 2 update-alternatives: using /opt/java_1.6.0_35/bin/java to provide /usr/bin/java (java) in auto mode. red-planet@laptop:~$ sudo update-alternatives --install "/usr/bin/javac" "javac" "/opt/java_1.6.0_35/bin/javac" 2 update-alternatives: using /opt/java_1.6.0_35/bin/javac to provide /usr/bin/javac (javac) in auto mode. red-planet@laptop:~$ sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/opt/java_1.6.0_35/bin/javaws" 2 update-alternatives: using /opt/java_1.6.0_35/bin/javaws to provide /usr/bin/javaws (javaws) in auto mode. And configured: There are 2 choices for the alternative java (providing /usr/bin/java). Selection Path Priority Status ------------------------------------------------------------ * 0 /opt/java_1.6.0_35/bin/java 2 auto mode 1 /opt/java_1.6.0_35/bin/java 2 manual mode 2 /usr/lib/jvm/java-7-oracle/bin/java 1 manual mode Press enter to keep the current choice[*], or type selection number: Why do I have two equal items in the list?

• Transfer page from internal to external

  - by Theo Gulland

  Afternoon all! Currently I have a website with a list of audio products (essentially a search engine for audio deals). http://www.soundplaza.co.uk Once you go to the details page, you can then press the 'view deal' button to go to providers site e.g. = http://www.soundplaza.co.uk/all-deals/113/bookshelf-speakers/acoustic-energy-1 This jump between two sites is a bit harsh and I would like to show a transition page, to simply ease them into another site and not scare them off. Within this tradition page I will have a simple loading gif and some graphics showing that your transferring. QUESTION: What is the best way to send the details (link, product name etc) to this transfer page, to then wait 5 seconds, to then move on to the desired link... this can in NO WAY damage my SEO, if anything rel="nofollow" would be great if possible. Currently I have seen that you can submit form to the transition page, then you can use php sleep and then php header to transfer... however I am not sure if php header will transfer SEO value tot he provider? Any opinions would be great! Thanks

• Is "as long as it works" the norm?

  - by q303

  Hi, My last shop did not have a process. Agile essentially meant they did not have a plan at all about how to develop or manage their projects. It meant "hey, here's a ton of work. Go do it in two weeks. We're fast paced and agile." They released stuff that they knew had problems. They didn't care how things were written. There were no code reviews--despite there being several developers. They released software they knew to be buggy. At my previous job, people had the attitude as long as it works, it's fine. When I asked for a rewrite of some code I had written while we were essentially exploring the spec, they denied it. I wanted to rewrite the code because code was repeated in multiple places, there was no encapsulation and it took people a long time to make changes to it. So essentially, my impression is this: programming boils down to the following: Reading some book about the latest tool/technology Throwing code together based on this, avoiding writing any individual code because the company doesn't want to "maintain custom code" Showing it and moving on to the next thing, "as long as it works." I've always told myself that next job I'm going to get a better shop. It never happens. If this is it, then I feel stuck. The technologies always change; if the only professional development here is reading the latest MS Press technology book, then what have you built in 10 years but a superficial knowledge of various technologies? I'm concerned about: Best way to have professional standards How to develop meaningful knowledge and experience in this situation

• Wake laptop when lid is opened?

  - by crackout12

  I have a SAMSUNG laptop, which by the experience in the last months, has been a great one. I am actually implementing some functionality to it, and since I noticed, I am able to wake up my laptop from sleep by just opening the lid on Windows 7, however, I need to press to power button to wake up in Ubuntu. Using a program called i-nex, I noted that the kernel DOES dettect a "lid switch", and I am looking forward to use it to wake up function. Any ideas? UPDATE: Thanks @yossile for bringing up some clues! However, output of command cat /proc/acpi/wakeup does not show the LID device. I still tried the second set of commands you gave me with no effect. Then I tried experimenting, guessing that LID should be named by other value, so I tried enabling the others. No victory so far. But I noticed that devices that did not have any pci listings were disabled at all time no matter what I tried. Here is the output of command cat /proc/acpi/wakeup: root@samsung:~# cat /proc/acpi/wakeup Device S-state Status Sysfs node PCE4 S4 *disabled pci:0000:00:04.0 SBAZ S4 *disabled pci:0000:00:14.2 P0PC S4 *disabled pci:0000:00:14.4 GEC S4 *disabled PE20 S4 *disabled pci:0000:00:15.0 PE21 S4 *disabled PE22 S4 *disabled pci:0000:00:15.2 PE23 S4 *disabled PWRB S5 *enabled So maybe it could be that LID is either GEC,PE21, or PE23? Still, there is /proc/acpi/button/lid/LID/state file which shows that LID is opened. Any more ideas?

• Moving player in direciton camera is facing

  - by Samurai Fox

  I have a 3rd person camera which can rotate around the player. My problem is that wherever camera is facing, players forward is always the same direction. For example when camera is facing the right side of the player, when I press button to move forward, I want player to turn to the left and make that the "new forward". My camera script so far: using UnityEngine; using System.Collections; public class PlayerScript : MonoBehaviour { public float RotateSpeed = 150, MoveSpeed = 50; float DeltaTime; void Update() { DeltaTime = Time.deltaTime; transform.Rotate(0, Input.GetAxis("LeftX") * RotateSpeed * DeltaTime, 0); transform.Translate(0, 0, -Input.GetAxis("LeftY") * MoveSpeed * DeltaTime); } } public class CameraScript : MonoBehaviour { public GameObject Target; public float RotateSpeed = 170, FollowDistance = 20, FollowHeight = 10; float RotateSpeedPerTime, DesiredRotationAngle, DesiredHeight, CurrentRotationAngle, CurrentHeight, Yaw, Pitch; Quaternion CurrentRotation; void LateUpdate() { RotateSpeedPerTime = RotateSpeed * Time.deltaTime; DesiredRotationAngle = Target.transform.eulerAngles.y; DesiredHeight = Target.transform.position.y + FollowHeight; CurrentRotationAngle = transform.eulerAngles.y; CurrentHeight = transform.position.y; CurrentRotationAngle = Mathf.LerpAngle(CurrentRotationAngle, DesiredRotationAngle, 0); CurrentHeight = Mathf.Lerp(CurrentHeight, DesiredHeight, 0); CurrentRotation = Quaternion.Euler(0, CurrentRotationAngle, 0); transform.position = Target.transform.position; transform.position -= CurrentRotation * Vector3.forward * FollowDistance; transform.position = new Vector3(transform.position.x, CurrentHeight, transform.position.z); Yaw = Input.GetAxis("Right Horizontal") * RotateSpeedPerTime; Pitch = Input.GetAxis("Right Vertical") * RotateSpeedPerTime; transform.Translate(new Vector3(Yaw, -Pitch, 0)); transform.position = new Vector3(transform.position.x, transform.position.y, transform.position.z); transform.LookAt(Target.transform); } }
