  1. Thanks for the link, that website is definitely worth remembering - I have on many occasions had to query friends to determine whether websites were down for everyone or just me
  2. While the Dvorak keyboard layout is often regarded as more efficient than the QWERTY layout, it does not follow that everyone should switch. Firstly, many pieces of software have keyboard shortcuts and commands that are designed for the QWERTY. For example undo, cut, copy, paste. The shortcuts for these commands are Ctrl-z/x/c/v. These shortcuts are intended to be operated with only ones left hand. In the Dvorak layout, these are moved to the positions of / . b i in the QWERTY layout. Constantly changing layouts to utilize these shortcuts is definitely going to lower productivity.Another note is that many users of the QWERTY layout are already very proficient, with typing speeds exceeding 100 words per minute, after years of practice. These speeds will take significant amounts of time to reach after switching, and many years would need to follow for the user to make up for the time lost while learning and mastering the new layout. Also, one's proficiency in the QWERTY layout is likely to decrease, which will negatively impact the user's performance on computers in which the user does not have access to modifying the keyboard layout.I'm not trying to make it seem like the Dvorak layout is bad - for users who are not able to type fast on the QWERTY layout, it may be beneficial to attempt switching layouts. Learning Dvorak is not actually too difficult - I had achieved about 60WPM after two weeks, but have since reverted to the QWERTY layout for the reasons listed above.
  3. This is incorrect, these infinite sets have exactly the same cardinality (see for example the pairing function which maps NxN onto N). The link you provided demonstrates that the real numbers (which we can create a one-to-one mapping against the power set of integers) has a higher cardinality from that of the integers. Again, incorrect. These infinities are of the same cardinality. The correct approach to determine the remaining income would be to take the limit of x-(x/t) as x approaches infinity (where t is the tax rate, between 0 and 1). This diverges to infinity as x approaches infinity, and hence one would still have infinite income.
  4. I think the key point which you are missing is that infinity is concept and not a real number, which is why the standard axioms do not hold.
  5. When you try to write an integer to a file, it is likely that it will be interpreted as a char. To append numbers to the file, you would need to use the toString method first to convert to a string, or concatenate it with a string (e.g. "myInt (converted to a string): "+myInt). The reason that the numbers you have sent to output are interpreted as a ? is likely to be that the bytes in the file which have been outputted from your program are not printable ASCII characters (i.e. 0-31, 127). If you open the file in a hex editor, then you should be able to see the output.
  6. StringIndexOutOfBoundsException is thrown when you attempt to invoke a method upon a string where the parameters passed would require accessing characters of the string which do not exist, such as negative numbers and those exceeding it's length (and possibly equal to). The JVM should automatically give information about the exception such as the line on which it occurred (I believe), but if it does not, then you can use try/catch to make it easier to pin down the lines which are causing the exception.
  7. If you place an icon as favicon.ico on the web root, it will automatically be used. The point of the HTML codes suggested by the above posters is to allow for different icons for different portions of a website. You do not need to explicitly write it if you do not need different icons and have access to the directory of the web site root (which you should!)
  8. If you had a virus preventing you to view hidden files, wouldn't it be better to first remove the virus? Also note that viruses can block access to the registry editor (although it isn't hard to get around this, for example safe mode).
  9. jay -> The shape of an object can be realized from the shading. Read Flatland for a deeper comprehension. cicala -> One dimension is merely length. Using time as a fourth dimension means that there is no reason why we can't have three dimensions as x, y, t - or two dimensions as x, t. Using another spatial dimension for the fourth dimension is probably more effective, also for the mathematics that may arise.
  10. Getting a bit off-topic here, but I think there's some way to set a master password which you will need to input for the saved passwords to be used or seen.
  11. I think you can also view the password to your cPanel if you log on to the Xisto - Support client area and view your product details.
  12. There exist code obfuscators to prevent this sort of decompiling. Off the top of my head, you could google for Amayeta, SWF Protect, and secureSWF. On top of code, I think it is possible to also obfuscate strings and variable names, but I don't see a possibility in obfuscating movie-clips, sound, and other objects created within the Flash IDE (obviously graphics created from code are protected). I suppose it would be possible to reverse-engineer the code from the pseudocode/assembly produced by a decompiler but this is somewhat infeasible for larger scale projects. In the Flash gaming industry, MochiAds (the most common ad platform) provides additional code obfuscation, but I don't really know the extent of how well it works.
  13. Dot points, because I can. > I am 15 years old and in university > I went to public schools > My closest friends are from high school, and I still talk to some primary school friends > I would hate being grouped with people at a significantly lower academic standard (and maturity) > Look into extra-curricular activities and programs for talented children (the 'head-fake'?) > Find what interests your child and help her learn it > Don't hold her back - if you can't get her into school early, see if you can have her skip from the first grade to the second some weeks into first grade.
  14. Try this: wget -O - -q -t 1 http://forums.xisto.com/no_longer_exists/ And for the timing - I don't see how you would need to run cron more than once a day, so probably pick any values for minute/hour and *'s for the other fields.
  15. You could try hacking something up using mod_rewrite. For example, you could rewrite http://forums.xisto.com/no_longer_exists/ to http://forums.xisto.com/no_longer_exists/=, which would redirect them based on the value in q. Hopefully this doesn't cause an infinite redirection loop..
  16. That one is for if you get a countdown for shutdown, which the original poster didn't mention at all. But if it is the case, it's shutdown -a, and you can type it straight from the run prompt (windows-r).
  17. I'm not seeing a problem here - you should note that both ActionScript and JavaScript ARE derivatives of ECMAScript, so they are extremely similar in form. There is only a single line needed when using SWFObject to create... an .swf object, and even if you have no programming experience (for example if you are only familiar with animating in Flash), it shouldn't be hard to work out how to operate this.
  18. You should be clear on the actual meanings behind the words kilobyte, megabyte, petabyte, etc. To comply with the International System of Units (SI), these terms should actually operate with powers of ten. In addition to this, the major standard-setting organizations such as the IEEE and ISO advocate the use of powers of ten. This means a kilobyte is 1,000 bytes, a gigabyte is 1,000,000,000 bytes, etc. For using powers of two, there are actually ways to show you want to use these. By taking the first two letters of the SI prefix and appending 'bi' (for binary) to the end, you get the terms kibibyte, mebibyte, etc. These explicitly show that you are talking about powers of two. To denote in symbolic form, you capitalize the initial character and add an 'i' in the middle - for example KiB for kibibyte, or 1024 bytes. So you should be careful when you say you are getting ripped off - Seagate would be correct in saying that the hard drive has space of 160 GB (well it probably isn't exactly 160GB, but that's irrelevant). This 160GB fits the 'proper' conventions for GB, and if you want to talk about powers of 2, then the size is (about) 149GiB. You are not getting ripped off 7.4%. Don't worry though too much, this mistake is commonly made - for example one of my computer science lecturers taught everyone the wrong conventions (and didn't see my hand when I was going to point this out - intentional? )
  19. I might be able to help, this is an example of work in progress...
  20. Firefox should not take 15 seconds to boot, unless you have a large number of addons installed, or are trying to start it up while opening a heap of other programs. It is possible to prefetch Firefox to make it load faster. As for print and bookmark buttons in Chrome, I would assume that these are omitted because it is much faster to hit ctrl-p or ctrl-d respectively. If you really need a print button, you could bookmark the following javascript snippet: javascript:window.print() and click on it when you want to print.
  21. If you want it on each page, you can simply have it saved to public_html/favicon.ico
  22. Well you can actually minimize the sections (click the [-] on the far right of the category names), but it does start to glitch if you minimize too much (by size) - this should probably be rectified.
  23. What? You do know that GUI means Graphical User Interface, right?
  24. As rvalkass said, ActionScript is extremely similar to JavaScript (as they are both based off ECMAScript), so knowing one would make the other very easy to learn (well knowing one programming language makes learning any other easy anyways). Using Flash in a web-page is not essential, and a portion of users will not have the necessary Flash Player installed (you can see the penetration statistics from the Adobe website). SM has the order of languages to learn quite well done - I would go with HTML, CSS, JS, PHP, then AS if you want to (make sure to learn AS3 instead of AS2, as it is significantly faster and matches the speed of Java (this doesn't really matter unless you're going to be doing something CPU-intensive like a complex real-time game)). Basically, JS and AS allows you to make web-pages more interactive, you can have a trail of dots appear when you move you mouse if you wanted to (but the user would get annoyed by it), or a comment form appear when you click a button (look at the Fast Reply button at the bottom of a thread here). Using Flash would be for more graphical oriented interactions. PHP is for server-side code, allowing for things such as forums (all these posts are stored on the database which is accessed via PHP).
  25. When the page has loaded, the onLoad function is called. This executes the javascript "document.title = 'Title 2'", which changes the document's title to 'Title 2'.
