What is the maximum amount of ram a 64bit machine can theoretically address?
I'm reading through my computer architecture book and I see that in an x86, 32bit CPU, the program counter is 32 bit. So, the number of bytes it can address is 2^32 bytes, or 4GB. So it makes sense to me that most 32 bit machines limit the amount of ram to 4gb (ignoring PAE). Am I right in assuming…

How to get multi-row sort/filtering headers in excel
I have a spreadsheet which uses 2 rows for header information. Filtering by selecting a column is implicitly assuming only 1 row of header information. Sorting has a header row checkbox but that only toggles treating the first row as a header. Is there a way to make Excel treat the first two rows a…
How good is PDF password protection?
It appears that Word's password protection is not really good, at least until Office 2003, if I read this SU entry correctly. I'm under the impression that Acrobat's PDF password protection should be better (it says 128-bit AES for Acrobat 7 and higher). Is that true? Of course, it depends on the s…

How to start Windows XP in Safe Mode when its a VirtualBox guest in a Mac OS X host?
I've tried tapping F8 as it boots up, but I just get the normal logon screen. I'm using a Mac Mini with an Apple keyboard, do I need to do something special to get it to recognise F8? I'm trying to install Guest Additions so that I can use DirectX, which is why I need safe mode.

How to Combine find and grep for a complex search? ( GNU/linux, find, grep )
I'm trying to do a text search in some files that share a similar directory structure, but are not in the same directory tree, in GNU/Linux.

Windows Taskbar - Prevent some applications from grouping?
This probably applies to either Vista or Windows 7...they both have a feature where it will group windows from the same app under a single button. However I have one application I want it to never group -- specifically an X11 server, where different windows are separate apps and not related (ie, I …
Force view text file instead of download in Firefox?
Often times I'll click on a random link to a or or or ... file in Firefox, and all I want is to view the code. I don't have a Firefox handler set up for every text file extension under the sun, and I don't want to have to. Is there an easy way to force Firefox to view the file as text instead of tr…

How can you make Excel 2007 stop formatting large numbers as scientific notation?
Kind of the inverse of this question. I frequently download CSVs from outside sources as part of my programming work. I like to examine their data in Excel because, let's face it, Excel is an ideal tool for this sort of thing. Except for one behavior: Excel attempts to outwit the data in the CSV, a…

How to diagnose Blue Screens in Windows 7 (64bit)
Using programs like WhoCrashed and BlueScreenView you can see the BSOD and the errors but how do you tell exactly what's causing the BSOD? I'm not sure if it's because of bad hardware, bad driver software or OS corruption. The computer seems to crash randomly at different points sometimes when bein…
