• How to determine whether a spread-sheet cell contains a date, or a real number?

  - by Everyone

  When a cell in a spreadsheet contains a simple date (mm/dd/yyyy) the poi API flags the cell-type as 'numeric'. This is probably because spreadsheets ( IMO ) historically recognize only strings and real numbers. It is possible to hard-code the cell-index, and use it conditionally to call 'getDateCellValue'. But this feels like a hack. What other ways are there in the poi API to determine whether the content in a cell is a Date rather than a real number?

• Windowless OpenGL

  - by ext

  Hi, I would like to have a windowless OpenGL context (on both GNU/linux with Xorg and Windows). I'm not going to render anything but only call functions like glGetString, glCompileShader and similar. I've done some goggling but not come up with anything useful, except creating a hidden window; which seems like a hack to me. So does anyone have a better idea (for any platform)?

• Detecting if youtube is blocked by company / ISP

  - by Simon_Weaver

  We have Youtube videos on a site and want to detect if it is likely that they will not be able to view them due to (mostly likely) company policy or otherwise. We have two sites: 1) Flex / Flash 2) HTML I think with Flex I can attempt to download http://youtube.com/crossdomain.xml and if it is valid XML assume the site is available But with HTML I dont know how to do it. I cant even think of a 'nice hack'

• PNG transparency of backgrounds to submit buttons or inputs of type image

  - by pokearood

  Hi bit of a silly question. Are there any png transparency issues with backgrounds to submit buttons or inputs of type image? Or do they behave fine just like img tags with a png image as the source. I understand for IE6 you need a hack for png transparency to work.

• How do I make a C++ Program print its own source code?

  - by Koning WWWWWWWWWWWWWWWWWWWWWWW

  Just as the title says: how do I make a simple hello world program which, instead of printing Hello World, prints its own source code? I thought about resource files, but I think they count as source code, or I could hack the executable, include the source code somewhere in the file. Can anyone point me in the right direction? Thanks

• view-port resize vs document resize in IE

  - by mkoryak

  window.resize event in IE doesnt do what i thought it does. I thought it only triggered when the physical window/view-port changed size (ie user hits maximize on the browser window for example), but it is also triggered if i change the document size, introducing scroll bars. is there any way to tell those two things apart: view port resize, and document resize without writing an elaborate hack?

• What is Logically and semantically correct, A-grade browsers compatible and W3C valid way to clear f

  - by metal-gear-solid

  What is Logically correct and W3C valid way to clear float? zoom:1 is not valid by W3C and IE8 don't have hash layout problem overflow:hidden and overflow:hidden were not made to do this,as the spec intended overflow to be used <div class="clear"/> is not semantically correct and i don't want to add extra markup. clearfix hack generates content that really hasn’t any semantic value. I've asked many questions and read many articles on this issue but haven't find best way.

• Can multiple wordpress's feed off one database?

  - by ThomasReggi

  I am a template designer and I want to create one wordpress with all generic posts, but I don't want to have to keep logging in and copy & pasteing the same wordpress posts everytime. Can I point multiple WP installs to one database? A harder way would be export a master db and importing it to each install. Before I go crazy and try to hack something together, does anyone have any advise? -Thanks in advance.

• How to parse HTML from JavaScript in Firefox?

  - by hmp

  What is the best way to parse (get a DOM tree of) a HTML result of XmlHttpRequest in Firefox? EDIT: I do not have the DOM tree, I want to acquire it. XmlHttpRequest's "responseXML" works only when the result is actual XML, so I have only responseText to work with. The innerHTML hack doesn't seem to work with a complete HTML document (in <html</html). - turns out it works fine.

• What's your favorite cross domain cookie sharing approach?

  - by Haoest

  I see iframe/p3p trick is the most popular one around, but I personally don't like it because javascript + hidden fields + frame really make it look like a hack job. I've also come across a master-slave approach using web service to communicate (http://www.15seconds.com/issue/971108.htm) and it seems better because it's transparent to the user and it's robust against different browsers. Is there any better approaches, and what are the pros and cons of each?

• Delete document with an empty ID

  - by Damien MATHIEU

  Hello, I have a CouchDB database in production. One of the documents has been edited (in Futon by an other developer). And it's lost it's ID (don't ask me how he did it). So now the document's id is an empty string, which makes it impossible to edit or delete via Futon. Is there a way I could hack into CouchDB to delete that document anyway ?

• How do I translate a ISO 8601 datetime string into a Python datetime object?

  - by Andrey Fedorov

  I'm getting a datetime string in a format like "2009-05-28T16:15:00" (this is ISO 8601, I believe) one hack-ish option seems to be to parse the string using time.strptime and passing the first 6 elements of the touple into the datetime constructor, like: datetime.datetime(*time.strptime("2007-03-04T21:08:12", "%Y-%m-%dT%H:%M:%S")[:6]) I haven't been able to find a "cleaner" way of doing this, is there one?

• Detecting suspicious behaviour in a web application - what to look for?

  - by Sosh

  I would like to ask the proactive (or paranoid;) among us: What are you looking for, and how? I'm thinking mainly about things that can be watched for programaticaly, rather than manually inspecting logs. For example: - Manual/automated hack attempts - Data skimming - Bot registrations (that have evaded captcha etc.) - Other unwanted behaviour Just wondering what most people would consider practical and effective..

• jQuery slideToggle - when div is toggled it pushes content out of viewable area (IE)

  - by Chris

  This is an annoying ocurrance in IE when I use the jQuery slideToggle effect. Without the div being open, page looks normal. The minute I toggle the div open, it extends past the current content, overtop of the footer, and out of the viewable browser area (Even after scrolling all the way down). This feature seems to work just fine in firefox. Do I need an additional hack or CSS to make it work in IE8?

• How to invert alternate bits of a number

  - by Cupidvogel

  The problem is how to invert alternate bits of a number, starting from the LSB. Currently what I am doing is first doing a count = -1 while n: n >>= 1 count += 1 to first find the position of the leftmost set bit, then running a loop to invert every alternate bit: i = 0 while i <= count: num ^= 1<<i i += 2 Is there a quick hack solution instead of this rather boring loop solution? Of course, the solution can't make any asumption about the size of the integer.

• Python List length as a string

  - by mvid

  Is there a preferred (not ugly) way of outputting a list length as a string? Currently I am nesting function calls like so: print "Length: %s" % str(len(self.listOfThings)) This seems like a hack solution, is there a more graceful way of achieving the same result?
