I'd like to mimic or emulate in a normal webpage how some of forums tags work if you click on them. For example, the "hide" tags in forums work by hiding a select amount of information on the page, which the reader can then expand/collapse by a simple mouse click. How would you enable that same action on a non-forums webpage? Or, some forums reveal an image if you mouse-over a word, and it disappears after you no longer mouse-over that word. I'm not looking to start a forums, it'll be a typical website using some handy forums operations.

Ah, vaccination makes sense. So, if a chicken house is free of salmonella and you don't introduce any new chickens, will there be no cases of salmonella for as long as no outside contamination is allowed to enter? (Test/vaccinate all new chickens) The same for livestock?

If a chicken lays an egg with salmonella, does that mean its other eggs from that same day will also have salmonella? How does the bacteria spread among chickens/livestock? There's only mention of how it spreads to people, rather than among chickens/livestock.

Thank you. 1. Seems to address what I'm looking for. So the OP is possible? 2. What's a container/thread? It sounds like a good and simple way to ensure the security of plug-ins. 3. How do you accomplish that?

How close technologically are we to the point where computers are fast enough that vector will be the default and most natural choice for all image formats of a typical size (2048 × 1536), including photographs and 3-D?

Can the .net stuff be used in Linux?

Is the ability for programs to screen record -- without dropping frames or missing anything important -- something that could be facilitated or made "natural" via the operating system? For example, can one build a Linux system to do that, making it easier/simpler for programmers to create a screen recorder exactly like the OP seeks?

Tough question, I guess eh?

If you program a software, can you limit how much freedom any plug-ins would have on the computer system? For example, let's say you programmed a book reader, an image editor, or a font creator, and it lets the user import any plug-ins for expanding its capabilities. Would you be able to limit the plug-in to a certain environment, like forbidding it access to the internet, critical system folders, or anything you think of? Can you sandbox it to affect only saved user files and only those within the install folder of your program (or a specified folder)? Basically, if your program is a trusted and dependable software, can you ensure the plug-ins will be as secure?

Here's an article that backs up what ydoaPs said. Kevin Houston, a mathematician at the University of Leeds in the U.K. who has made a YouTube video to explain all the advantages of tau over pi, said the most compelling argument for tau is that it is a much more natural number to use in the fields of math involving circles, like geometry, trigonometry and even advanced calculus. "When measuring angles, mathematicians don't use degrees, they use radians," Houston enthusiastically told Life's Little Mysteries. "There are 2pi radians in a circle. This means one quarter of a circle corresponds to half of pi. That is, one quarter corresponds to a half. That's crazy. Similarly, three quarters of a circle is three halves of pi. Three quarters corresponds to three halves!" "Let's now use tau," he continued. "One quarter of a circle is one quarter of tau. One quarter corresponds to one quarter! Isn't that sensible and easy to remember? Similarly, three quarters of a circle is three quarters of tau." Making tau equal to the full angular turn through a circle, he said, is "so easy and would prevent math, physics and engineering students from making silly errors." ..... Indeed, other tau advocates have said they've noticed a significant improvement in the ability of students to learn math, especially geometry and trigonometry where factors of 2pi show up the most, when the students learn with tau rather than pi. Though 2pi appears much more often in calculations than does pi by itself (in fact, mathematicians often accidentally drop or ad that extra factor of 2 in their calculations), "there is no need for pi to be eradicated," Houston said. "You might say I'm not anti-pi, I'm pro-tau. Hence, anyone could use pi when they had a calculation involving half of tau."

The computer doesn't have an operating system, so I can't run programs or find out settings. But it's an AMD Athlon X2 4400+ 2.3 GHz, with 2GB DDR2 800MHz. @insane The burning software is probably NERO which is on a friend's computer. I don't know the version, but it's fairly recent (within three years or so).

I want to download and install Linux Mint, but they give two versions for download: 32-bit or 64-bit. How do I find out which is the correct one to use? Then, after I download it, how would I go about creating the Live DVD? -- Simply burn the files onto a blank DVD? If so, would it have autorun included by default? Or is that something I'd have to add onto the disk somehow?

Ok thanks, I'll check it out again. Yes, and possibly a Mac notebook when I get one. I'd like to be able to transfer whatever between all three kinds of computer, as I'm able to do right now with my 2GB USB thumb drive. However, the largest transfers are going to be from one Windows system to another (from 10 to 300 GB worth of data). That is, until I get comfortable enough with Linux that all I'll bother with is Linux. I'll be trying out Linux Mint, which is supposed to be highly user-friendly. So we'll see.

1) I just connected the external USB drive to a Linux, and when I opened it, a hidden folder is visible: System Volume Information. Wondering if deleting that folder will undo the Microsoft permissions crap. 2) Right-clicking on the USB drive lets you format it, and clicking to do so gives these options... Compatible with all systems (FAT) Compatible with Linux (ext2) Compatible with Linux (ext4) So, since there are no more options given except a button that leads to advanced formatting stuff, I'm left with the impression that FAT is the standard in such cases. Else, why does the pendrivelinux website give specific advice to format a larger USB drive with FAT32? I didn't see an option to specify FAT32, but maybe it's there once you select FAT and proceed to the next step (which I haven't yet).

Thank you, Cap'n. From the Microsoft website... How can I tell if XP is on a domain? (No idea what that is)

What a hoot

I don't think (for programming) one has to re-invent the entire wheel per se, but that in a way, one does have to reconfigure the system practically from the ground up. The real wheel has more of a luxury: one doesn't use a wheel to craft an evolved wheel, but one does use a program to create an evolved type of programming. Without re-invention of computer programming, we might get a butterfly effect type pile-up of consequences, where all the little inefficiencies carried over from earlier seedlings of programming might begin a growing chain of inefficiencies that at the end negatively affects performance and over-complicates everything in the system.

What does that mean exactly?

Here's the deal, formatting it as NTFS created the problem. Or at least with XP Professional it did (Service Pack 3). Or maybe I did the format wrong -- although I simply right-clicked on the external drive's letter and selected the default choice: NTFS.

From what I'll reasonably guess, computer languages and implementation decisions have evolved sort of ad-hoc, which if true is one reason for the difficulty level of mastering computers. Another element, I'd suppose, is the loss of any paths that could've a) streamlined design, b) focused more on best practices, and/or c) increased overall efficiency. To elaborate, such a path can be any worthwhile fork in the past's road of computer developments that for a reason got abandoned/neglected/overlooked (for a less effective one?). If we add up all such instances of lost paths, those might be enough, potentially, to compound the overall level of complexity creep* in today's systems. The point I'd like to discuss is this: how possible would it be for computers to be leagues easier for its designers/coders, language builders, and most everyday home or office users....if the focus were on clean code, making programmer languages intuitive even for beginner designers/coders, standards of interoperability, and elegance from the basic structure of algorithms to the computer's interaction with any other digital hardware? i.e...would computer science -- and understanding the vast world of computers -- be anywhere near to so difficult then? *Rather than complexity, I prefer to say complication. To me, the word complexity evokes an image of simple parts intertwined in a complex harmony or pattern: a rose's bouquet; good wine or notes of flavors combining in microbrewed beers; DaVinci's paintings. Complicated, on the other hand, is like a clashing of messy parts: the legal system; corporate bureaucracies, technical instruction manuals; loophole filled tax codes.

If you were to draw out the difference between a Fat32 and NTFS system to a kid, how would your explanation go? What's the crux of the differences between a computer engineering and computer science?

I just got a brand new Seagate 500GB external drive. It came bundled with stuff I didn't want, so I formatted the drive. And that's something I'm not used to as it's my first time attempting it. So I probably screwed up. The first thing I did is to right-click on the drive letter and select "Format". I guessed XP would determine the best option, and since "NTFS" was highlighted I clicked that. So after forever, the drive's clear of everything and so I start moving files over. No problem. Then when I go to delete or move some of those files later on, I get an error. Seems all folders were given a "read-only" attribute. I try unchecking those, but I'm denied access. According to Microsoft, you're supposed to claim ownership of a folder with that problem. But since I can't understand their directions, I'm just going to reformat. It'll be much quicker than the days or weeks I'll spend figuring out directions by technically-minded people. Also, what if claiming ownership of folders on an external drive makes the same problem for transfer to other computers? No thanks. I'd rather not have anything Microsoft "fixing" the drive. Here's what I really need to know. An article at the pendriveapps website mentions that anything on a Fat32 drive is transferable between Linux, Mac, and Windows. If true, it's my best option anyway because I do have a user-friendly Linux named Mint on another desktop, and probably will get a cheap older MAC later on. I clicked on a their link to an article for a tiny program named Fat32 Format (72KB). Supposedly it will allow a Fat32 on a drive over the 32GB limit imposed by Windows. Because of the compatibility of files on a Fat32 with other systems, I'm guessing there won't be an issue like the one I had with the transferred files. However, because of my screw-up earlier in the day, I'd like to run it by computer heads before proceeding. And maybe someone can lay out directions step-by-step to format a drive in case I'm not doing it correctly. Thank you in advance.

I asked on Gmail forums 3 times but it seems my questions were removed, because in each instance they disappeared and got replaced by this notice highlighted in red: "part of your question has been removed". Except the question's completely gone without an explanation or notice sent to me. The question... "Can you get SMS email alerts from only specific people, so you don't get alerts from any other emails?" Maybe someone here can answer it for me. Any of you with Gmail care to try posting the same question on its forums? When you enter Gmail, click on "help" at left ---> forum. I'd like to know if the same happens to your question. I'd also like know if you can get the alerts without the email's contents, just a notification that an email's awaiting you from a person, but not the whole email's contents or images/attachments. I'm unfamiliar with the entire process and SMS texts in general.

Is there any modern PC or supercomputer design built so reliably that it doesn't ever go "blue screen", crash, or have glitches of a sort (where you must reboot it every now and then)? Or if so...does every computer have a back-up system no matter how flawless its performance?
