• how to set html table max-width?

  - by George2

  Hello everyone, I have an html table, and one column (<td>) has long text, so I want to set the max-width of the column -- so that if text is longer than the max-width, the text could auto-wrap to next line. I have tried to use css max-width style on related TD element of the column, something like "max-width:100px", but it does not work (text still very long and not auto-wrap to next line if it is very long). Any ideas what is wrong or any solution reference code? I am using IE 8 on Windows 7. thanks in advance, George

• java: relationship of the Runnable and Thread interfaces

  - by Karl Patrick

  I realize that the method run() must be declared because its declared in the Runnable interface. But my question comes when this class runs how is the Thread object allowed if there is no import call to a particular package? how does runnable know anything about Thread or its methods? does the Runnable interface extend the Thread class? Obviously I don't understand interfaces very well. thanks in advance. class PrimeFinder implements Runnable{ public long target; public long prime; public boolean finished = false; public Thread runner; PrimeFinder(long inTarget){ target = inTarget; if(runner == null){ runner = new Thread(this); runner.start() } } public void run(){ } }

• How to automatically switch monitors with my laptop dock

  - by Cas

  I have a Dell Precision M4300 with a Dell Dock PRO1X running Ubuntu Natty. When I have the laptop docked the lcd display is off and I use two external monitors however when I undock the laptop it does not switch to the laptop screen. The same happens when I dock the laptop, it does not switch to the external monitors. If I reboot the laptop it will choose the correct setup but it will not automatically change monitors with Ubuntu running. My Xorg.conf

• How to troubleshoot ethernet port on laptop

  - by Psallas Vassilios

  I have a problem with my wired connection. To be more specific, my laptop doesn't seems to recognize that I have plugged in an ethernet cable. I tried to download new drivers for my ethernet card, but I couldn't find any solutions. Maybe because I am new to Linux, so I'm not familiar with running commands in the terminal. OK I have typed the command and here are the results: 00:04.0 Ethernet controller [0200]: Silicon Integrated Systems [SiS] 191 Gigabit Ethernet Adapter [1039:0191] (rev 02) For the second reply I don't know if the following is what you asked me: ?Memory: 3.9 GiB ?Processor: Intel Core 2 Duo CPU P8800 @ 2.66GHz × 2 ?OS type: 32-bit My Ethernet connection had some problem on Windows too. I have changed recently my internet provider, and since then my ethernet cable is not recognized by the laptop. At that time I was still on Windows. I thought that with Ubuntu the problem would be solved, but unfortunately the problem still persists. If someone can help me to solve my problem I'll be thankful. Here are the results of the three first commands you told me to run: lsmod | grep sis190 sis190 22570 0 sudo modprobe sis190 ifconfig eth0 Link encap:Ethernet HWaddr 00:90:f5:90:81:7e UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:185 errors:0 dropped:0 overruns:0 frame:0 TX packets:185 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:22672 (22.6 KB) TX bytes:22672 (22.6 KB) wlan0 Link encap:Ethernet HWaddr 00:25:d3:2c:3a:ae inet addr:192.168.1.72 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::225:d3ff:fe2c:3aae/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:260 errors:0 dropped:0 overruns:0 frame:0 TX packets:363 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:71992 (71.9 KB) TX bytes:52000 (52.0 KB) and the results of running the last two commands: dmesg | grep -e eth -e sis190 [ 0.816667] sis190: sis190 Gigabit Ethernet driver 1.4 loaded [ 0.816728] sis190 0000:00:04.0: setting latency timer to 64 [ 0.816751] sis190: 0000:00:04.0: Read MAC address from EEPROM [ 0.904032] sis190: 0000:00:04.0: Realtek PHY RTL8201 transceiver at address [ 1.416030] sis190: 0000:00:04.0: Using transceiver at address 1 as default [ 1.448235] sis190 0000:00:04.0: eth0: 0000:00:04.0: SiS 191 PCI Gigabit Ethernet adapter at f8410000 (IRQ: 19), 00:90:f5:90:81:7e [ 1.448238] sis190 0000:00:04.0: eth0: GMII mode.

• Explicitly multiplying values as longs

  - by Bill Szerdy

  I understand that all math is done as the largest data type required to handle the current values but when you transverse a loop how do you explicitly multiply longs? The following code returns 0, I suspect, because of an overflow. long result = 0L; List<Long> temp = (List<Long>) getListOfIntegers(); for (int i = 0; i < temp.size(); i++) { result *= temp.get(i).longValue(); } System.out.println(result);

• Any "trick" to use some keys to launch an application?

  - by Profete162

  Hello, I am currently developing an free application (TaskOS ) that allow users to have multitasking and switch easily between applications on their mobile ( like alt+tab in Windows ) That work pretty well and user can launch my application by a long press on the "search" button" by adding this line in the manifest: <action android:name="android.intent.action.SEARCH_LONG_PRESS" /> I also succeed to allow to the users to Use the camera button ( they can of course disable that in application settings) and the way to do that is slighlty different: <receiver android:name=".CameraPressed"> <intent-filter android:priority="10000"> <action android:name="android.intent.action.CAMERA_BUTTON"/> </intent-filter> I am now wondering if there are other ways to launch easily my task switcher? ( long press on Home key, long press on trackball, or any other idea.) Reading the Google documentation does not help me a lot. Any other idea/suggestion would be warmly welcome. Christophe

• Opening Large (24 GB) File In C

  - by zacaj

  I'm trying to read in a 24 GB XML file in C, but it won't work. I'm printing out the current position using ftell() as I read it in, but once it gets to a big enough number, it goes back to a small number and starts over, never even getting 20% through the file. I assume this is a problem with the range of the variable that's used to store the position (long), which can go up to about 4,000,000,000 according to http://msdn.microsoft.com/en-us/library/s3f49ktz%28VS.80%29.aspx, while my file is 25,000,000,000 bytes in size. A long long should work, but how would I change what my compiler(Cygwin/mingw32) uses or get it to have fopen64?

• Where to split a string literal

  - by quinmars

  Every time I have to split a long string literal into two (or more) pieces, because it does not fit into a single line, I have to decide if I split the text before or after a space. For example: const char * long_text1 = "This is a long text, which does not fit " "in one line"; /* or */ const char * long_text2 = "This is a long text, which does not fit" " in one line"; I tend to use the first way, but I do not have a real reason for it. So I wonder is there any advantage to favor one of them? I know this questions tend to be coding style question, but that's not my intend. I only want to know if there is a convincing reason why one of those two ways might be preferable.

• Why does Compiz keeps crashing?

  - by odeh86

  I am running Ubunutu 14.04 x86_64. Compiz keep crashing frequently and I can't work on my laptop. If I have media running or so I can still hear the audio and its just Compiz that is crashing as I see in some crash logs. I tried to reset both Compiz and Unity but still it is not working. Is there a solution or should I jump back to Gnome? Here are the commands that i tried:- dconf reset -f /org/compiz/ unity-reset setsid unity

• 12.04 Unity 3D 80% CPU load with Compiz

  - by user39288

  EDIT : I have been able to to determine that the problem is not compiz, but is actually Xorg. I don't know why, but by quickly maximizing terminal and taking a screenshot with top running before the problem went away I am able to see xorg takes up 72% of cpu, with bamfdaemon taking up 18%, and compiz taking up 14%. Seems the nvidia drivers are to blame, will play more with settings and perhaps do a clean nvidia-current install to try to fix the problem. Having a very annoying problem with high CPU usage. Running 12.04 with latest drivers and nvidia-current installed. Have not had any issues for days, now I have a strange problem. Unity 3d runs great most of the time, 1-2% CPU usage with only transmission running in background. Windows open and close smoothly. However,no matter what programs are open, if I minimize all open programs to the unity bar on the left, my CPU jumps to about 80% and slows down all maximize and minimize effects. Mouse movement stays smooth the whole time, but unity becomes unresponsive for up to 30 seconds at times. Hitting alt + tab to bring up even a single window fixes the problem. The window I bring back up doesn't even have to be maximized to solve the problem. Hitting the super button to bring up the dash makes CPU drop back to idle until I close it, then high CPU usage resumes. Believe the problem is compiz, but even just having only terminal running "top", I have to minimize it to the tray for the problem to show, so I can't see the problem process. I can only tell about the high CPU usage using indicator-sysmonitor. Even tried quitting the indicator, but I can still tell very poor performance with all applications when minimized. Reset compiz back to defaults, tried going to the post-release update nvidia drivers, played with vsync settings in both the nvidia settings and compiz. Even forced refresh rate, but cannot solve the problem. The problem does NOT occur in Unity 2D. Specs are core 2 duo 2.0ghz, 4GB ddr2 ram, 2x 320's HDD in RAID 0, and Nvidia GTX 260M graphics card.

• Can't sync music on Nexus 4 with rhythmbox

  - by luca992

  My LG Nexus 4 phone running Andriod 4.4.3 will not sync music with rhythmbox, banshee, or clementine with my laptop running Ubuntu 14.04. When attached via USB2 or USB3 I can mount the file system on the phone without issue and can manually transfer files but attempting to sync my nexus with any of the three music players I listed causes them to crash. I realize it is probably some mtp issue. But I cannot figure out why the music players cannot connect to my nexus and nautilus has no problem doing so.

• Java M4A atom tagging free space issue

  - by Brett

  Hey, I've been trying to be able to read and write iTunes style M4A atoms and while I've successfully done the reading part, I've come to a bit of a halt in regards to the free space atoms. I figured that I should be able edit and shift the padding around to accommodate writing an atom with more data than it originally had. I've been stuck on this for about a day now, and I've been trying to figure out how to determine the closest free space atom with enough size to accommodate the new data. so far I have: private freeAtom acquireFreeSpaceAtom( long position ) { long atomStart = Long.MAX_VALUE; freeAtom atom = null; for( freeAtom a : freeSpace ) { if( Math.abs( position - atomStart ) > Math.abs( position - a.getAtomStart() ) ) atomStart = ( atom = a ).getAtomStart(); } return atom; } That code only takes into account the closest free space atom and completely disregards the fact that it should be greater than or equal to a certain size, but I can't quite figure out how I should check for both closeness and size efficiently.

It captures one screen but doesn't show the rest. I can capture my screen running if I use my flip camcorder but recordmydesktop will not work. Is there a way to capture live video playing on the desktop without using an outside camera? Brian

• Returning S_FALSE from a C# COM dll

  - by AntonyW

  I have a method defined in IDL as follows : interface IMyFunc : IDispatch { [id(1), helpstring("method GetNextFunction")] HRESULT GetNextFunction([in,out] long* lPos, [out, retval] BSTR* bstrName); } Using C++ I always implemented this as follows : STDMETHODIMP CMyFunc::GetNextFunction(long *nID, long *lPos, BSTR *bstrName) { if ( function to return ) { // setup return values; return S_OK; } else { // just exit return S_FALSE; } } Now I am implementing this in C# and have used tlbimp on the type library and ended up with : public string GetNextFunction(ref int nID, ref int lPos) I understand that this is because [out, retval] is used as the return type instead of the HRESULT as in C++. Is there a simple way to return the S_OK / S_FALSE values without changing the method definition? The only way I can see is that I have to use ildasm / ilasm to add preservesig so I end up with something like this : public int GetNextFunction(ref int nID, ref int lPos, ref string bstrName) I was wondering if there was some other way without doing the il compilation step.

• How can I get my HID device working in VirtualBox?

  I'm running the latest official Ubuntu build of VirtualBox (4.1.12), with Windows 8 running as the guest OS. I have a Windows app that works with a card reading HID device, but it's not detected by the guest OS at all. I've installed the USB extensions, guest additions and set my udev rules accordingly (my own linux app is able to access the device), but no joy. Does anyone know how to get this working?

• How does one implement a truly asynchronous java thread

  - by Ritesh M Nayak

  I have a function that needs to perfom two operations, one which finishes fast and one which takes a long time to run. I want to be able to delegate the long running operation to a thread and I dont care when the thread finishes, but the threads needs to complete. I implemented this as shown below , but, my secondoperation never gets done as the function exits after the start() call. How I can ensure that the function returns but the second operation thread finishes its execution as well and is not dependent on the parent thread ? public void someFunction(String data) { smallOperation() Blah a = new Blah(); Thread th = new Thread(a); th.Start(); } class SecondOperation implements Runnable { public void run(){ // doSomething long running } }

• Can I safely store UInt32 to NSUInteger?

  In the header, it is defined like: #if __LP64__ || (TARGET_OS_EMBEDDED && !TARGET_OS_IPHONE) || TARGET_OS_WIN32 || NS_BUILD_32_LIKE_64 typedef long NSInteger; typedef unsigned long NSUInteger; #else typedef int NSInteger; typedef unsigned int NSUInteger; #endif So does an UInt32 fit without problems into an NSUInteger (an unsigned int)? Where's the difference between UInt32 and unsigned int? And I assume that an unsigned long is bigger than an unsigned int?
