• Dual-boot: Can't select Windows at boot

  - by user88561

  I have a computer with 2 operating systems dual booted: One is Windows 7 and the other is Ubuntu. In the bootloader configuration, I removed an option stating time to select OS and I also set the default Operating System to Ubuntu. Now the bootloader is effectively proceeding into auto loading Ubuntu, while skipping itself. My problem is that I can not access my Windows 7 Operating System. Could someone give me a clue as to what to do?

• How do I get a transparent page/screen in Firefox?

  - by s0dafire

  So, everytime I open a new tab (about:newtab) or just a white screen (about:blank). It would be better, Firefox displays my desktop instead (or what's 'behind' firefox) to work more efficient. I thought to try Firefox's Add-On 'Stylish' to solve this problem, but those scripts are only for Windows with Aero support. So... any other ideas how I get a transparent page/screen in Firefox? EDIT To clean things up: I don't want the whole window transparent!

• Resize/Create a New Partition in GParted

  - by Charlie

  So I've been having some trouble recently with Ubuntu and decided it was time to switch to windows. But I have no ntfs partitions on my hard disk and GParted will not let me resize my one large partition (/dev/sda1) so that I can allocate some ntfs space to install windows on. Any help would be greatly appreciated, I've had this problem for quite some time now and it had just become one big headache. Thanks in advance!

• 3D models overlapping each other

  - by Auren

  I have a problem at the moment when I draw some models to teach me more about 3D game programming. The models at the moment overlaps each other from some angles witch makes sense since the game at the moment draws from left to right, line after line. However my question is: Is there any easy escape from this issue or is there any way that you could draw the in-game world from the players position? I would really appreciate if someone could give me some answers on this.

• Cocos2D - Detecting collision

  - by Grace

  I am a beginner in cocos2d and im facing a problem with detecting collision for my coins. Sometimes it works sometimes it doesn't. So basically, im creating a game which the user (ship) have to avoid the obstacles and collect coins on the way. The collision of the obstacle works well but not for the coins. I was thinking maybe the loops for creating many coins is the problem but im not sure. Can anyone help? My codes: - (void)update:(ccTime)dt{ double curTime = CACurrentMediaTime(); if (curTime > _nextBridgeSpawn) { float randSecs = [self randomValueBetween:3.0 andValue:5.0]; _nextBridgeSpawn = randSecs + curTime; float randX = [self randomValueBetween:50 andValue:500]; float randDuration = [self randomValueBetween:8.0 andValue:10.0]; CCSprite *bridge = [_bridge objectAtIndex:_nextBridge]; _nextBridge++; if (_nextBridge >= _bridge.count) _nextBridge = 0; [bridge stopAllActions]; bridge.position = ccp(winSize.width/2, winSize.height); bridge.visible = YES; [bridge runAction:[CCSequence actions: [CCMoveBy actionWithDuration:randDuration position:ccp(0, -winSize.height)], [CCCallFuncN actionWithTarget:self selector:@selector(setInvisible:)], nil]]; this is where i declare my coins (continued from the update method) int randCoin = [self randomValueBetween:0 andValue:5]; _coin = [[CCArray alloc] initWithCapacity:randCoin]; for(int i = 0; i < randCoin; ++i) { coin = [CCSprite spriteWithFile:@"coin.png"]; coin.visible = NO; [self addChild:coin]; [_coin addObject:coin]; } float randCoinX = [self randomValueBetween:winSize.width/5 andValue:winSize.width - (border.contentSize.width *2)]; float randCoinY = [self randomValueBetween:100 andValue:700]; float randCoinPlace = [self randomValueBetween:30 andValue:60]; for (int i = 0; i < _coin.count; ++i) { CCSprite *coin2 = [_coin objectAtIndex:i]; coin2.position = ccp(randCoinX, (bridge.position.y + randCoinY) + (randCoinPlace *i)); coin2.visible = YES; [coin2 runAction:[CCSequence actions: [CCMoveBy actionWithDuration:randDuration position:ccp(0, -winSize.height-2000)], [CCCallFuncN actionWithTarget:self selector:@selector(setInvisible:)], nil]]; } } this is to check for collision (also in the update method) for (CCSprite *bridge in _bridge) { if (!bridge.visible) continue; if (CGRectIntersectsRect(ship.boundingBox, bridge.boundingBox)){ bridge.visible = NO; [ship runAction:[CCBlink actionWithDuration:1.0 blinks:5]]; } } } //this is the collision for coins which only work at times for (CCSprite *coin2 in _coin) { if (!coin2.visible) continue; if (CGRectIntersectsRect(ship.boundingBox, coin2.boundingBox)) { NSLog(@"Coin collected"); coin2.visible = NO; } } } Thank you.

• Wifi problems with Ubuntu 13.10

  - by Sparrowhawk4

  I should probably say straight off that I am brand new to Ubuntu. I installed 13.10 alongside Windows 7 a couple of days ago and I've managed to clear up all the little problems, apart from with the wifi. My internet is fine using an ethernet cable. I can connect to the wifi, and it tells me that the signal is good, but for the vast majority of the time I can't load anything, and system monitor tells me that I am sending and receiving nothing. The problem is somewhere in Ubuntu. It works fine on Windows 7, my Android phone and all of my flatmates laptops. I know I'm not the only one with this problem, but the fixes I've seen either don't work or I don't understand them enough to carry them out. Help?

• Why does Ubuntu really slow down the rest of my home network?

  - by tympaniplayer

  I have a ubuntu Dekstop and a Windows 7 Desktop. The windows 7 is connected via wireless adapter and the ubuntu dekstop is connected via ethernet. The wireless adapter is capable of 300Mbps link speed. When my ubuntu is connected to the interet, the network becomes very very slow. I have a 15 Mbps cable broadband connection. I have had many devices connected at one with no problem, yet this one connection seems to be wreaking havoc.

  I've been looking to get into research, but I'm not sure I can do when I've only taken two quarters of Computer Science. I go to the University of Washington, if it's relevant. This is a page on research. I find that I'm not able to judge what is possible for a first year looking through the website. Most things look intimidating, but I'm sure I could somewhere on some problem if I actually attacked it.

  I have Broadcom bcm43224 wifi card with proprietary broadcom sta driver. At home wifi connection works well, but in the office when I ping some resource there is a lot of loss packets and I cant browse websites.

I've tried loading earlier kernels [3.2.0 ] but that hasn't helped. I've tried playing with alsamixer, unmuting and raising volume, doesn't work I've tried playing with pauvcontrol, doesnt work. Althought, strangely, when i play a song, under output i can see a bar moving implying that something is working, just the sound isn't getting through my speakers. Thus it might be a hardware problem. I've tried unistalling and reinstalling pulsaudio annd alsamixer, doesn't work [maybe made it worse...]. I've heard reverting back to kernel 3.0... works, but i'm reluctant to try that[i dont know much about kernels]. Thank you. Please tell me what other information you need. EDIT: My audio has started working again after another reboot. However this time im not connected to my external audio on startup. I will see if this is the issue next time i'm at home Edit: Connecting to external audio is not the problem.

• Are non-modified FILESTREAM files excluded from DIFFERENTIAL backups?

  - by TiborKaraszi

  Short answer seems to be "yes". I got this from a forum post today, so I thought I'd test it out. Basically, the discussion is whether we can somehow cut down backup sizes for filestream data (assumption is that filestream data isn't modified very frequently). I've seen this a few times now, and often suggestions arises to somehow exclude the filestream data and fo file level backup of those files. But that would more or less leaves us with the problem of the "old" solution: potential inconsistency....(read more)

• How to stop Office 2010 changing " and ' to smart quotes

  - by fatherjack

  I have recently upgraded to Office 2010 at work and there are a few things that are a real problem for me. As a T-SQL developer and SQL Server DBA I copy and paste code to and from various applications and if Word gets involved it can has disastrous consequences. There is an option that appears to be defaulted to "on" that changes a straight quote to what Word describes as a smart quote - see the image below. Note - the single quote suffers from the same effect. Now, getting to the point that...(read more)
