Tried removing the overflow hidden, but that does not seem to fix it. Suggestions? Relevent HTML and problem illustration here: http://mgc.selfip.com/bugscreen01.jpg Relevent CSS #nav{padding: 5px 0px; overflow: hidden; background-color: #7af;} ul#nav{white-space: nowrap;} #nav li{display: inline; list-style-type: none;} #nav li a{padding: 5px 10px;} #nav a{font-family: "Adobe Caslon Pro", "Hoefler Text", Georgia, Garamond, Times, serif; font-size: 14pt; font-variant: small-caps;} #nav a:link, #nav a:visited{color: #fff; text-decoration: none;} #nav a:hover, #nav a:focus{color: #fff; background: #91db24;}

How do I set font size to 0px in IE6?

- by Justin808

I have an unordered list, I'm trying to hide the text in the list. I can do this 2 ways that i know of: font-color: transparent; font-size: 0px; I prefer the 0px method as its not selectable. This issue is neither way works in IE6. The first way just doesn't work in IE6 at all, the 2nd leave a 1PX high font. Is there a way to hide the text in IE6? This is a visual thing, I know you can read the text by reading the source and that is OK, I just need it to visually not be there.

Is there any way to store full size image returned from camera activity in internal memory ?

- by SimpleGuy

I am using Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(externalFileObj)); intent to call default camera activity. To get full image you need to specify intent.putExtra(). But this always requires URI that works only for external storage files. I tried to create a temp.jpg image in internal memory and pass its URI Uri.fromFile(new File(getFilesDir() + "/temp.jpg")); but the camera activity won't return back after the image is captured. So there is no way to get Full size image from default camera application in our activity without using any external storage ? Assuming that the device do not have SD card or currently in use is there no way I can avoid using it ? Yes I know we can create our own camerapreview surface but I want to use the default camera application as it is natural with many more options. Thanks.

DB2 increase bufferpool size and compressed tables not equal better performance. Why?

- by Mestika

Hi, I’m working on tuning and increasing the performance of my IBM DB2 version 9.7 database. I’ve been searching around the net for the last couple of days and learned that if I created my tables in COMPRESS mode and created one more bufferpool and set both of them to access 1024mb, then the performance in my queries should increase because of the less I/Os to the disks. However, when I run my time analysis, the performance Decrease. I added the new additions to my regular database with the indexes I’ve used all the time. Each time I search google I come up with the statement that: Increased bufferpool size and several bufferpools AND a table compression SHOULD prove to get better performance. I’m very puzzled about the total unexpected result. Are there some tuning mechanisms I’ve forgot or does anyone have a explanation for this odd behavior? Sincerely Mestika

is there a way to use cin.getline() without having to define a char array size before hand?

- by zebraman

Basically my task is having to sort a bunch of strings of variable length ignoring case. I understand there is a function strcasecmp() that compares cstrings, but doesn't work on strings. Right now I'm using getline() for strings so I can just read in the strings one line at a time. I add these to a vector of strings, then convert to cstrings for each call of strcasecmp(). Instead of having to convert each string to a cstring before comparing with strcasecmp(), I was wondering if there was a way I could use cin.getline() for cstrings without having a predefined char array size. Or, would the best solution be to just read in string, convert to cstring, store in vector, then sort?

Proper way to handle issue when porting 32 to 64 bit. Conversion from DT1 to DT2 of greater size

- by grobartn

So I am trying to port 32 bit to 64 bit. I have turned on the VS2008 flag for detecting problems with 64 bit. I am trying following: char * pList = (char *)uiTmp); warning C4312: 'type cast' : conversion from 'unsigned int' to 'char *' of greater size Disregard the code itself. This is also true for any pointer, because 64 bit pointer is greater than 32 bit unsigned int or int for that purpose. Given that you have to cast smaller type to greater how would you go about doing it so it correctly on both 32/64 bit systems

Is this the best way to get the size of a Paper via CUPS?

- by Lawrence Johnston

I've got a CUPS job control file. I need to get the actual dimensions of the print that was made. This is the way I've figure out to do it: Get the paper name using the media attribute. (e.g. Letter) Get the printer uri from the printer-uri attribute. (e.g. ipp://localhost/printers/MyPrinter) Get the printer name by passing the printer uri to the IPP_GET_PRINTER_ATTRIBUTES operation and getting the printer-name attribute. (e.g. MyPrinter) Get the path to the PPD passing the printer name to the the cupsGetPPD method. Open the PPD passing the path to the PPD to the ppdOpenFile method. Get the paper size by passing the PPD and paper name to the ppdPageSize method. This will work, but it seems a bit roundabout. Is there a more efficient way of getting what I need?

Is allocating a dynamic array without specifying size well formed code?

- by Als

The following simple program snippet gives compilation errorswith gcc-4.3.4. Program: int main() { char *ptr = new char[10]; char *ptr1 = new char[]; return 0; } Compilation errors: prog.cpp: In function ‘int main()’: prog.cpp:4: error: expected primary-expression before ‘]’ token prog.cpp:3: warning: unused variable ‘ptr’ prog.cpp:4: warning: unused variable ‘ptr1’ But the same compiles cleanly with MSVC without any diagnostic message. So my question is: Does the Standard allow an new [] to be called without specifying the size? Or this a bug in MSVC? Can someone provide a reference from the standard which will conclusively say that the above code example is ill-formed or well-formed? I have had a look at: 5.3.4 New [expr.new] & 18.4.1.2 Array forms [lib.new.delete.array] but couldnt find any conclusive evidence about the behavior.

C++ std::equal -- rationale behind not testing for the 2 ranges having equal size?

- by ShaChris23

I just wrote some code to test the behavior of std::equal, and came away surprised: int main() { try { std::list<int> lst1; std::list<int> lst2; if(!std::equal(lst1.begin(), lst1.end(), lst2.begin())) throw std::logic_error("Error: 2 empty lists should always be equal"); lst2.push_back(5); if(std::equal(lst1.begin(), lst1.end(), lst2.begin())) throw std::logic_error("Error: comparing 2 lists where one is not empty should not be equal"); } catch(std::exception& e) { std::cerr << e.what(); } } The output (a surprise to me): Error: comparing 2 lists where one is not empty should not be equal Observation: why is it the std::equal does not first check if the 2 containers have the same size() ? Was there a legitimate reason?

I want to read an audio file into multiple byte arrays , with different size . And then add into a shared memory. What will happen if use below code. Does the byte array gets over written. I understand it will creat multiple byte array , how do i erase those byte arrays after my code does what it needs to do. int TotalBuffer = 10; while (TotalBuffer !=0){ bufferData = new byte[AClipTextFileHandler.BufferSize.get(j)]; input.read(bufferData); Sharedbuffer.put(bufferData); i++; j++; TotalBuffer--; }

Can I rebuild degraded RAID1 on a SAS 5 i controller with a larger mirror drive size?

- by Kenny

A drive failed on a Dell SAS 5i controller - see controller bios screengrab: http://imagebin.ca/view/SkZbszA.html The primary is a 160GB 10k sata drive. I added a 250GB 7k rpm drive in the hope that the array would rebuild onto this drive. This did not happen. (assuming that the controller would just operate at the speed of the slowest drive) The controller could see the new drive, but it didn't automatically rebuild the raid1 onto this drive. (my assumption is that it did not do this rebuild as the drive sizes are different). There was an option to add the new drive to the existing raid1 array - but when I tried this a message appeared stating that all data on the array would be lost. (I didn't get a screenshot of this message, I will later) Should the SAS 5i allow me to rebuild the array onto a larger drive? Is the option to add the drive to the array the right way to go? Many thanks!

In MySQL 5.1 InnoDB, does the maximum length of a VARCHAR affect secondary index size?

- by e_tothe_ipi

Assuming the data is the same either way, does the maximum length of the VARCHAR affect the space usage of a secondary index? Does InnoDB use fixed length records for indexes? Assume that we're talking about MySQL 5.1, with the InnoDB COMPRESSED table format and that the field in question is defined as a VARCHAR with some length less than or equal to 255 (so that it uses only one byte for the offset). Here is the use case: I have a server with a very large table (several gigabytes). One of the fields is currently VARCHAR(7). We need it a little longer and we are thinking of making it VARCHAR(255), but we are worried that it bloat the index.

Why after deleting a 110+ GB collection, my /var/lib/mongodb directory still have same size?

- by tunnuz

I am having some troubles with MongoDB and space usage. In particular, I once used to have a large collection of about 600 million records totaling 110+ GB on disk. Recently I decided to drop it because the data was outdated, to do so I dropped the collection through rockmongo's web interface. Accordingly, rockmongo doesn't show me the collection anymore, however my disk usage hasn't changed at all. Is there any clean operation which I am not aware of, which must be run in order to synchronize the database with database files on disk? I have tried to perform a "repair" but the system complains that there's not enough space on disk ... that's because it is all used by MongoDB.

Change Windows 7 start menu height depending on monitor size?

- by hippietrail

I know I can change the height of the Windows 7 Start Menu so that includes more or fewer recently used apps, etc. But I have a netbook with a tiny screen that I plug into a decent sized LCD most of the time at home. Is there a way to get Win7 to use a taller Start menu with more items when I'm using the LCD and a shorter Start menu with fewer items when using the netbook's built in screen? (I'm a programmer so capable of technical solutions if there's no ready-made solution.)

Can I replace a broken PSU with one of a smaller size?

- by Carson Myers

I have a broken OEM power supply unit that is cooked. I'm browsing online to find a replacement and am happy to see that they don't cost too much -- the only thing is they all seem to have varying sizes. Is it a problem if I get a PSU that is smaller than the original one? This is going in an HP Pavillion a000, it's about five and a half years old -- I don't know if that means anything, I just thought there might be some recent standardized dimensions for PSUs or something. No idea.

Can a file change size when the transfer protocol changes?

- by djechelon

I am very curious about what I have just found happening on my computers. I have set up SyncBackPro to synchronize a music folder from my home desktop to my laptop using Windows network share (SMB). Files get synchronized regularly. Now I tried to switch to FTP and I noticed that NO FILE matches its counterpart even if they have never been modified (I make sure there is the readonly flag and no application is allowed to retag MP3s and whatever...), so SyncBack asks me what side should overwrite the other. FTP files are a little larger than local files. I run synchronization from the laptop. How can such a thing happen? Files are the same, bytes should be the same... If I run SMB sync again it matches all the files again.

Finding a shared HDD attached to the network from my F-13 machine

Sorry for the slew of n00bie questions, but here is one more. I recently partitioned my 1.5TB harddrive according to this question I then bought this to attach the harddrive to my network. The problem is, how do I navigate to the hard drive to move files over the network to the HDD. should this be moved to serverfault? update: the disk isn't even showing up when i call "fdisk -l" (as root). How can I mount it if I can't even find it?

How can I increase the size of a Windows 2003 NTFS partition?

- by waszkiewicz

Hi everybody! I have a very important server running Windows Server 2003 and my System partition is becoming too small, it's slowing down the machine. I have already tried all the cleaning stuff and transferring some "unimportant softs" on the "Saves" partition but it didn't help much at all. Is there a way to re-partition my hard-drive that will work on a 2003 Server, that's not too expensive and that could be used without turning the machine off. If there is no other way, then I'll have to reinstall the OS, but it will have to wait for the weekend. Thanks for your suggestions.

Is computer's DRAM size not as important once we get a Solid State Drive?

- by Jian Lin

I am thinking of getting a Dell X11 netbook, and it can go up to 8GB of DRAM, together with a 256GB Solid State Drive. So in that case, it can handle quite a bit of Virtual PC running Linux, and Win XP, etc. But is the 8GB of RAM not so important any more. Won't 2GB or 4GB be quite good if a Solid State Hard drive is used? I think the most worried thing is that the memory is not enough and the less often used data is swapped to the pagefile on hard disk and it will become really slow, but with SDD drive, the problem is a lot less of a concerned? Is there a comparison as to, if DRAM speed is n, then SDD drive speed is how many n and hard disk speed is how many n just as a ball park comparison?
