Why is using the xhost command such a bad thing? What should I use instead?

Math Department Computing FAQ
In X, when you use "xhost +machine," you are using host-based authentication. What this means is that you are allowing anyone on "machine" (including yourself, which is probably what you only want) access to your X session. A mischievous person could simply annoy you by running programs that display to your screen, while a malicious person could record every keystroke that you type. In short, xhost and host-based authentication are not secure.

So is that a bad thing?

Well it's bad for two reasons. One, it isn't good to have metal stuck in your paint for obvious reasons, and less obvious is that over time it can actually compromise the paints integrity. Secondly, it looks and feels bad. No one wants rough paint.

Why not use adult stem cells instead of using human embryonic stem cells in research?

FAQs [Stem Cell Information]
Human embryonic stem cells are thought to have much greater developmental potential than adult stem cells. This means that embryonic stem cells may be pluripotent—that is, able to give rise to cells found in all tissues of the embryo except for germ cells rather than being merely multipotent—restricted to specific subpopulations of cell types, as adult stem cells are thought to be.

How do I use the command line instead of dialog boxes?

AutoCAD FAQ: Frequently Asked AutoCAD Questions, Troubleshoo...
Beginning with AutoCAD 2000, several commands changed to utilize a dialog box for input. Prior to AutoCAD 2000 one command produced a dialog box, another prompts on the command line. For instance, typing DDINSERT displayed the Insert dialog box, while typing INSERT prompted for input on the command line. This change can wreck havoc on customized menus in later versions of AutoCAD. To use the command line version, include a hyphen (-) in front of a command: -INSERT.

I'd like to be able to press a key to send a voice command, instead of using the menus. But how?

Why do my controls look bad when I use CreateWindow to create them instead of a dialog?

EFNet #Winprog
When a window is created, it is given the default System font. Dialog Boxes use the default GUI font. To make a window use the appropriate font (that does not look so ugly) one must set the windows font to the GUI font. To do this, one uses WM_SETFONT to send the default GUI font which we get from GetStockObject() The following code is a sample function that create's a window and assigns it the GUI font.

How do i use the Next command?

Are points a good thing or a bad thing?

Illinois Mortgage Rates - Help and FAQ (frequently asked que...
Neither. Points are just one more option to consider when getting a loan. Most people choose not to pay any points, but that in itself doesn't make points bad. For some borrowers, paying points is a great way to lower their monthly mortgage payments. For other borrowers, that money might be better used elsewhere. It really depends on your situation, how long you plan to be in the property, how much available cash you have, how much you expect interest rates to change in the future, etc.

Why not use chlorine instead?

Water Filters, Purifiers, and Purification FAQ
Chlorine changes the tastes and odor of water. Chlorination can also produce harmful by-products called Trihalomethanes (THMs) which are linked to incidence of cancer.

Why should I use a Mohel instead of a doctor?

Frequently Asked Questions - Emoil.com/Emohel.com

Why do you use a DTD instead of a schema?

MusicXML FAQ (Frequently Asked Questions)
When we started developing MusicXML, a DTD (Document Type Definition) was the only official W3C recommendation for defining an XML document. Since that time, XML Schemas have become an official W3C recommendation, and alternative schema languages like RELAX NG have also become available. W3C XML Schemas offer many benefits when using XML in electronic commerce and business database applications. For musical documents, though, the advantages are less compelling.

Why do you use all these elements instead of attributes?

MusicXML FAQ (Frequently Asked Questions)
This is mainly a stylistic decision. Several XML books advise representing semantics in elements rather than attributes where possible. One advantage of doing this is that elements have structure, but attributes do not. If you find that what you are representing really has more than one part, you can create a hierarchical structure with an element. With attributes, you are limited to an unordered list.

Why is betting for your team such a bad thing?

Frequently Asked Questions
The possibility exists that decisions won't be made in the team's best interests, but rather because of the money riding on the game. If a manager bets on a game, he may bring a player off injured reserves sooner than he should in order to win, or he may pitch a reliever without enough rest, not caring that he won't be able to pitch for several extra days. If a betting manager gets in large debt to bookies, he can clear his account by merely revealing inside information about the team.

I use the EXTRACT command and get the message "Extraction anchor not found". What is the solution?

FAQ - iMacros
The reason for this message is that the extraction anchor, given mainly by the ATTR parameter of the EXTRACT command, could not be found on the currently active web site. Make sure that you selected the appropriate part for the anchor. It should only contain HTML code that does not change during each session or the changing parts need to be replaced by the wildcard *. Incorrect: This anchor does not work because it contains a changing value (the dollar amount).
