• Drive Shows No Files But Half Space Gone

  - by Chance Robertson

  I have a 500 GB USB drive. When I go to Windows Explorer or Finder, the drive shows that about half the drive is free. However, when I open either drive in Windows 7 or OS X, no files how up. I have tried to look at the files through the command line and nothing shows. A while back, I hooked it up to my MacBookPro and there was a quick message that said the drive was not ejected properly, blah, blah. And of course I did not read the message and hit OK. It there any way to get back my files from the drive?

• PASS Summit 2011 &ndash; Part I

  - by Tara Kizer

  What an amazing week I had at PASS Summit 2011 in Seattle, WA!  I hadn’t attended a PASS conference since September of 2005 when it was in Grapevine, Texas.  It has grown so much since then.  I am not sure how many people attended back then, but I’d guesstimate about 1500.  They announced that at this year’s conference there were 4000 attendees.  WOW! Here are my favorite aspects of this conference: Networking! – Not only did I meet a lot of new people, but I also got to meet people in person that I’ve known on the Internet for years like Mladen Prajdic (blog|twitter) and Rob Volk (blog|twitter).  I even met someone that I’d recently helped out in the SQLTeam forums.  Learning – I took a lot of notes during the sessions I attended and plan on blogging very soon about them.  It is amazing the amount of things you learn and the things that you unlearn.  Yes I said unlearn.  Some of the stuff that I thought I knew was either out-dated or just plain wrong.  Fun, fun, fun – To say that this conference was fun would be an understatement.  I had a blast!  I attended the “Welcome Reception and Quizbowl” on Tuesday night, the “Exhibitor Reception” on Wednesday night, and the “Community Appreciation Party” at GameWorks on Thursday night.  There were many other after-hours events to attend, but I had to make my kids a priority at night so I had to get back to my hotel room before 9pm so that I could Skype with them.   It was very entertaining reading and posting with #sqlpass on Twitter.  Twitter has changed the conference experience for the better.  I will definitely be able to do my job better due to attending this conference.  The return on investment is HUGE!

• How to setup an iTunes library to use between two Macs?

  - by stead1984

  As you can tell this is no where near work related. I have an iMac G5 where my itunes is currently hosted, I have also just got a new MacBook Pro. What I want to be able to do is sync my itunes library from my iMac to my MacBook Pro, that way it can be accessible away from my home network, then if I make any changes to the itunes library (like change a track name) it will sync these changes back once I connect back to the home network. My current itunes contains music, videos, podcasts, playlists and iPhone apps, I would also like iTunes to track play counts collectively between the iMac and the MacBook Pro.

• Create indefinitely oscillating pendulum in Farseer Physics 3.3.1/Box2d

  - by GONeale

  I am new to Farseer Physics and using version 3.3.1. I am after some help and would even be happy to receive Box2d answers just to ensure I get a response as I should then be able to convert it! -- Thanks ...After a lot of tinkering around I have managed to produce a thin vertical rectangle shape on the screen and I wish this to swing back and forth pinned at the top up to an angle I set (90 degrees would be fine for this sample). When it is approaching the top I wish it to slow down, then fall back the way it just came, increase speed then obviously slow to a stop at the top again. Almost how a swinging pirate ship would work at a theme park. This is the code I have so far which swings the shape, but it is seeming to lose speed on each swing eventually grinding to a halt: float playerWidth = ConvertUnits.ToSimUnits(5), playerHeight = ConvertUnits.ToSimUnits(68); playerPosition = ConvertUnits.ToSimUnits(-350, 0); playerBody = BodyFactory.CreateRectangle(World, playerWidth, playerHeight, 2f, playerPosition); playerBody.BodyType = BodyType.Dynamic; // create player sprite based on player body _rectangleSprite = new Sprite(ScreenManager.Assets.TextureFromShape(playerBody.FixtureList[0].Shape, MaterialType.Player, Color.Orange, 1f)); // Create swinging joint var joint = JointFactory.CreateFixedRevoluteJoint(World, playerBody, ConvertUnits.ToSimUnits(0, -34), playerBody.Position); If somebody could also provide the command I would need to pause the shape on a mouse click or keyboard command at it's current angle and then continue when I let go of the mouse click that would be super fantastic! (I actually posted this on StackOverflow as well before I realised there was a dedicated game development forum) Cheers

• Is DevCon.exe still the best way to restart/power cycle USB ports after resuming from hibernation in

  - by ProfessionalAmateur

  I have a USB broadband card on my Windows 7 laptop. It loathes resuming from hibernation properly. Back in the XP days I would issue a call devcon.exe from the command prompt and restart the selected ports (Saves you having to manually unplug and plug back in your USB devices). Ive been trying this is Windows 7, but the UAC keeps getting in the way. I'll start a command prompt. Issue the devcon command, but UAC asks me if I really want to do this, when I click yes it opens a different command prompt and launches the command. After the command completed this new prompt window closes faster than the speed of light and I cannot see the results. So Im thinking there has to be a better way to do this in the Vista/Win7 world...?

• How to stop OS X from switching input method (keyboard layout) automatically?

  - by adolf garlic

  After using the wireless keyboard that comes with the iMac, I have switched to a MS Ergo Natural 4000 one. Surprisingly I had to install extra software as OS X could not work out which keyboard I had. After which I went into sys prefs and set the main input method to be "British - Microsoft" first and "Swiss German" second (what the wireless keyboard is), on the "input sources" tab: However... OS X keeps resetting my input method back to Swiss German which is driving me bananas. I have the flag thingy top right so I can see when this changes. N.B. I have "input source options" set to "use the same one in all documents" which I am assuming means keep the language the same for anything running. It also flips back on the login page. Does anyone know how to fix this?

• Updating sprite location with controls

  - by iQue

  So ive got a character in a 2D game using surfaceView that I want to be able to move using a button(eventually a joystick), but my game crashes as soon as I try to move my sprite. This is my onTouch-method for my steering button: public void handleActionDown(int eventX, int eventY) { if (eventX >= (x - bitmap.getWidth() / 2) && (eventX <= (x + bitmap.getWidth()/2))) { if (eventY >= (y - bitmap.getHeight() / 2) && (y <= (y + bitmap.getHeight() / 2))) { setTouched(true); } else { setTouched(false); } } else { setTouched(false); } and if I try to put this in my update-method: public void update() { x += (speed.getXv() * speed.getxDirection()); y += (speed.getYv() * speed.getyDirection()); } the sprite moves on its own just fine, but as soon as I add: public void update() { if(steering.isTouched()){ x += (speed.getXv() * speed.getxDirection()); y += (speed.getYv() * speed.getyDirection()); } the game crashes. Does any1 know why this is or how to fix it? I cannot figure it out. Im using MotionEvent.ACTION_DOWN to check if the user if pressing the screen. }

• Firefox and Flash requires 2 clicks after Scrolling?

  - by Kerry

  I've noticed this with me and my partners computers, take a look at this: http://www.uploadify.com/demo/ Those buttons are flash. If you scroll (scroll to the bottom then back up, using your mouse scroll) then hover over a button, it is a normal pointer, not a hand. If you click on the button, then it turns into a hand, then you can click on it to trigger the browse files window. Is there any way to fix this? Is this a Firefox bug (doesn't happen in Chrome or IE8)?

• Ubuntu 9.10: switch in KVM, mouse is detected but not usable immediately

  - by CarlF

  I use a KVM switch to jump between my tower and laptop, both placed on my desk. With Ubuntu 9.04 this worked perfectly. In 9.10, when I switch to the tower, then back to the laptop, the mouse is detected (as shown by /var/log/messages) but moving it has no effect. If I use Ctrl-Alt-F1 to switch to the TTY, then Alt-F7 back to Xorg, the mouse starts working. The tower is running Windows 7, but that shouldn't matter. Sometimes, but not other times, the USB keyboard on the KVM switch is also not usable and I have to use the laptop's built-in keyboard to switch to the TTY. The laptop has two monitors, the built-in and an external. It's (obviously) the external panel that is attached via the KVM switch. Any suggestions? Report to Canonical as a bug?

• PC doesn't power up anymore

  - by Andrew

  I will tell you the story behind the problem. The computer needed to be reinstalled, it has 2 HDDs so I had to un-plug one to see which is which, to save as much data as possible. After unplugging the first one, it booted with the reinstallation CD, it wasn't the HDD I was looking for so I turned it off and unplugged the other one. After unplugging and turning on, right after booting test, the HDD was turned off, only the CPU fan was working. Turned it off with the power supply's button help, holding the power button didn't do it. And now it doesn't want to turn on anymore. I tried with another test power supply but the result is the same, doesn't want to turn on. Any idea?

• How to re-add RAID-10 dropped drive?

  - by thiesdiggity

  I have a problem that I can't seem to solve. We have a Ubuntu server setup with RAID-10 and two of the drives dropped out of the array.

Any help would be greatly appreciated. Thanks!

• Mercurial mirror: abort: No such file or directory: http://[...]/00manifest.i

  - by Sridhar Ratnakumar

  I am trying to setup a daily mirror of a mercurial repository - code.python.org in particular - within our local network, and serve that via Apache HTTPD. On the remote host that hosts apache, I did this: $ cd /var/www $ hg clone http://code.python.org/hg/trunk/ On my macbook, I ran: $ hg -v clone http://remote/trunk/ (falling back to static-http) abort: No such file or directory: http://remote/trunk/.hg/store/00manifest.i Google does not show any relevant result for this particular error. I remember back in those days being able to setup Bazaar mirrors by a simple clone. Doesn't Mercurial work like that? How do I setup a mirror that must further act like a clone URL?

• Recover files after unsuccesfull partitioning

  - by arsan

  I wanted to install another Linux on my comp, so i tried to resize one of my NTFS partitions with Norton Partition Magic, but it didn't complete successfully and it showed some errors and said that the partition is not resized and that it's the same size like before, but when i rebooted my comp i couldn't open that partition anymore and also i am not able to mount it from my linux. So this is my question: I had very important data on that partition - can i recover it back ? I guess nothing's deleted it's just something messed up so it's not usable, but can i get it back ? Please if there's any possible way of doing it, reply to me, thank you.

• Player sprite moving slower on iPhone 4

  - by nvillec

  I just finished getting movement/jump animation for a player sprite in Xcode using Cocos2D. The basic movement algorithm is a timer that updates every 0.01 sec, changing the sprite position to (sprite.position.x + xVel, sprite.position.y + yVel). Each time a movement button is tapped, the appropriate velocity (initialized to 0) is changed to whatever speed I choose, then a stop movement button returns the velocity to 0. It's not an ideal solution but I'm very new at this and stoked to at least have that working with little help from the internet. So I may not have explained that perfectly, but it is in fact working to my satisfaction in Xcode's iPhone Simulator, however when I build it for my device and run it on my phone, the sprite's movement speed is noticeably slower than in Xcode. At first I thought it must have to do with the resolution of the iPhone 4, making the sprite's movement path twice as long, but I found that if I pull up the multitask bar, then return to the app the speed will sometimes jump back to normal. My second theory was that the code is just inefficient and is bogging the processes down, but I would see this reflected in the frame rate wouldn't I? It stays at 59-60 the whole time, and the spritesheet animation runs at the correct speed. Has anyone experienced this? Is this a really obvious issue that I'm completely missing? Any help (or tips for optimizing my approach to movement) would be much appreciated!

• Windows XP volume control spontaneously slides to zero

  - by Paul Dixon

  Was listening to a podcast in iTunes at my desk, left my desk briefly and as I sat down, the volume faded. If I scrolled the volume back up, using my keyboard or the volume tray icon, it would smoothly scroll back down again. I rebooted, same thing occurred. Figuring maybe I had a stuck keyboard or hitherto undiscovered mouse function, I unplugged each in turn. Volume still wanted to go to zero! Anyone know what might cause this? It's driving me nuts!

• When can you call yourself good at language X?

  - by SoulBeaver

  This goes back to a conversation I've had with my girlfriend. I tried to tell her that I simply don't feel adequate enough in my programming language (C++) to call myself good. She then asked me, "Well, when do you consider yourself good enough?" That's an interesting question. I didn't know what to tell her. So I'm asking you. For any programming language, framework or the like, when do you reach a point were you sit back, look at what you've done and say, "Hey, I'm actually pretty good at this."? How do you define "good" so that you can tell others, honestly, "Yeah, I'm good at X". Additionally, do you reach these conclusions by comparing what others can do? Additional Info I have read the canonical paper on how it takes ten-thousand hours before you are an expert on the field. (Props to anybody that knows what this paper is called again) I have also read various articles from Coding Horror about interviewing people. Some people, it was said, "Cannot function outside of a framework." So they may be "good" for that framework, but not otherwise in the language. Is this true?

• Backup and restore.

  - by Xavierjazz

  I have a Thinkpad T60 with a 150GIg internal hard drive. XP Pro SP3. I also have a similar hard drive that used to be in another laptop connected via USB. It contains only data. I have cleared out a lot of duplicate files and now would like to back both up. I have Retrospect and a brand new 1Tbyte drive for this purpose. Can I back up the whole computer (both drives) but, in case only one fails, can I just restore that drive or do I have to restore both drives at the same time? I don't understand how partitions work so might I be able to partition the 1T drive and restore each smaller drive independently? Thanks.

• Is Oracle Database Appliance (ODA) A Best Kept Secret?

  - by Ravi.Sharma

  There is something about Oracle Database Appliance that underscores the tremendous value customers see in the product. Repeat purchases. When you buy “one” of something and come back to buy another, it confirms that the product met your expectations, you found good value in it, and perhaps you will continue to use it. But when you buy “one” and come back to buy many more on your very next purchase, it tells something else. It tells that you truly believe that you have found the best value out there. That you are convinced! That you are sold on the great idea and have discovered a product that far exceeds your expectations and delivers tremendous value! Many Oracle Database Appliance customers are such larger-volume-repeat-buyers. It is no surprise, that the product has a deeper penetration in many accounts where a customer made an initial purchase. The value proposition of Oracle Database Appliance is undeniably strong and extremely compelling. This is especially true for customers who are simply upgrading or “refreshing” their hardware (and reusing software licenses). For them, the ability to acquire world class, highly available database hardware along with leading edge management software and all of the automation is absolutely a steal. One customer DBA recently said, “Oracle Database Appliance is the best investment our company has ever made”. Such extreme statements do not come out of thin air. You have to experience it to believe it. Oracle Database Appliance is a low cost product. Not many sales managers may be knocking on your doors to sell it. But the great value it delivers to small and mid-size businesses and database implementations should not be underestimated.

• Synaptics touchpad problem when disabling it and then enabling it

  - by CYREX

  My girlfriend has an HP dv6000. In ubuntu 10.10 32bit i use the synaptic on it and all is good but when i disable it and enable it the problem starts. when i press the disable button in the synaptics touchpad it disables the mouse AND the keyboard. After enabled the Keyboard keys and Mouse clicks do not work. If i click on the panel below, for example the Applications, Places or System buttons the focus gets stuck there forever. I can open nautilus by clicking on it but i can not use the menus, the ALT+F2 function, see the wireless connections, lower the sound through the panel, etc.. Here comes the weird part. If i press CTRL+ALT+F1 (or any other tty for that matter) and then come back to CTRL+ALT+F7 where the gui is everything works perfect again. This started about a week ago but she told me right now. i checked dmesg which is for sometime now throwing some warnings about Skipping EDID probe do to cached edid but for what i could find out this did not create the problem in the start. NOTE: I do not need to login when i do CTRL+ALT+F1 i just need to change to another tty then come back to F7. What could be causing this problem?

• Can I upgrade a Windows 2000 domain to 2008 and demote the 2000 server without clients attached?

  - by techie007

  Hi all, We're planning to replace a Windows 2000 domain controller with a new 2008 DC (new hardware). We've elected to take the route of getting the 2000 domain schema up-to-snuff, join the 2008 server, upgrade it to a DC, and after replication demote the 2000 server (eventually to be taken off-line). The goal being to not have to visit all the workstations, and limited domain down-time. :) We want bring the old server here and do all the backups, Domain prep, migration and role transfers here, and then (hopefully) just plop the new 2008 back in place after it's done, and join the 2000 server back as a member server (so we can then do folder migrations, etc.). Can this server work be done off-site, without the workstations attached? If we do this will anything need to be done to the clients, once the new DC is physically in place, so they contact the new 2008 DC; or will they just 'know' and continue on using the existing domain settings/user profiles, etc.? Thanks in advance! :)

• The Importance of Fully Specifying a Problem

  - by Alan

  I had a customer call this week where we were provided a forced crashdump and asked to determine why the system was hung. Normally when you are looking at a hung system, you will find a lot of threads blocked on various locks, and most likely very little actually running on the system (unless it's threads spinning on busy wait type locks). This vmcore showed none of that. In fact we were seeing hundreds of threads actively on cpu in the second before the dump was forced. This prompted the question back to the customer: What exactly were you seeing that made you believe that the system was hung? It took a few days to get a response, but the response that I got back was that they were not able to ssh into the system and when they tried to login to the console, they got the login prompt, but after typing "root" and hitting return, the console was no longer responsive. This description puts a whole new light on the "hang". You immediately start thinking "name services". Looking at the crashdump, yes the sshds are all in door calls to nscd, and nscd is idle waiting on responses from the network. Looking at the connections I see a lot of connections to the secure ldap port in CLOSE_WAIT, but more interestingly I am seeing a few connections over the non-secure ldap port to a different LDAP server just sitting open. My feeling at this point is that we have an either non-responding LDAP server, or one that is responding slowly, the resolution being to investigate that server. Moral When you log a service ticket for a "system hang", it's great to get the forced crashdump first up, but it's even better to get a description of what you observed to make to believe that the system was hung.

• Google Chrome is in Danish

  - by Mad Cow

  I'm not sure what i have done, but by default, Chrome comes up in Danish. I can ignore this most of the time but its v annoying and i cant seem to change it. For example google directions come up in Danish too and have to be translated back to English! I have tried the spanner icon, and i've confirmed the only two languages specified are En and US English. Does anyone have any ideas how i can default it back to English all the time. In-lined the original screenshot from www.cow-shed.co.uk Thanks

• Why don't windows of the same application behave as they should?

  - by Yuttadhammo

  Somewhere along the upgrade path, Unity has developed some strange logic behind window layering. First, before Oneiric, there was a way to see all the windows of an application - I think it was when you click on the icon in the launcher. Now, clicking on the icon often does nothing. Suppose I have two terminals open, one behind this Firefox window, and one in front of it. Clicking on the launcher does nothing - the only way to find the second terminal, afaics, is to move the Firefox window or use the task switcher. Secondly, once I have both terminals on top, then I decide to close one of them, suddenly they both disappear (the second one, for some reason, has gone into hiding behind the Firefox window). Third (though I can't pin it down now), sometimes when a window is on top, focus is still on a window in back; I click on the top x to close the window in front, only to find I've closed an important window in the back. (Update: this question details the problem) I can't really believe these are bugs, since they seem too obvious to not have been fixed by now. My question is, am I missing something? Some compiz option I can set to make it act like it used to? Or is this really how Unity is supposed to act?
