  • website creation - for non web programmers?

    - by Tim
    I thought I would find decent questions and answers for this, but none really caught my eye... I am a C++ developer and I own a few domains. I'd like to start off with simple web sites for each with a minimum of time and fuss and minimum learning. I have too many projects going and don't have the time to learn how to build websites. One is for a company that currently has only a single product with custom development as well. I hacked together some really bad html with paypal links on it. It is just one simple product. I want to add uservoice to it and maybe some other stuff like FAQ, forums, etc. Right now I just link to a google group I created. Another is a startup in development phase, but we want to provide simple content like whitepapers and press releases and a section for investors. - mostly an "about us" type of thing. We will also be providing details about our product. Then there is a blog site - currently using godaddy's quickblogcast. Not a bad start but I suspect I want to move to something else. The question is - is there a framework that I can use that will make decent, if not outstanding, sites? Again, I have my hands full with three projects in addition to my day job and don't have time to learn web programming. I also don;t want to just pay a web person and then be out in the cold for upgrades, changes, etc. I have been burned before. I am happy with a web-based app or a desktop app that builds html or whatever and then I can ftp it up to the hosting servers. To summarize: - simple to get started - low time to get a web page going - ability to integrate with a few hand-done pages - pay pal integration - uservoice integration - ability to put under my svn would be nice too EDIT Thanks to the responders. I understand now why my original searches failed. I was not searching for "CMS". I'll go back and do that. I would expect that this is a many-times-duplicate... EDIT: I am considering using Wordpress and Drupal - one for each of the sites. I did one Drupal site quickly just so I could qualify for one of the Microsoft programs for discounted dev tools - anyway - it was a quick and dirty homepage and I am still on the learning curve. I look forward to playing with it. So far it has been ok. I am not sure about doing a taste-test between the two - might be a waste of time where I could just become that much better at Drupal faster than spending time on wordpress... Will keep updated. EDIT: Selecting the Drupal answer by slim for now. That is what I am going with. Don't have time to check them all out. Wordpress sounds like a good option too, but such limited time... Results: I have tried wordpress and drupal so far. Wordpress is great for blogging or for a site that you want to run ads from, but I disagree that it is ready for a corporate site, unless you want to spend lots of time making your own theme, etc. But if you spend that time, why not work with drupal? Drupal was a little intimidating at first - but after spending about 4 hours reading the overview and step-by-step guide online was a HUGE step. I got a simple site up and running easily after that. Trying to make a website just by going to the admin panel without reading anything is a waste of time. You really need to read the docs. The site is great. start here: http://drupal.org/getting-started I'd suggest drupal to anyone. It has amazing capabilities, lots of support and lots of users. Just doing blogging? Wordpress is really great for that. So now I've got two sites running with a lot of the functionality I wanted - and they look good. ONE MORE EDIT Well, I have switched back to wordpress after buying a theme and then getting help from web developers. I guess either one will work - it is just a matter of getting comfortable witht he basics, using the right tools and trying things out.

  • python simple function error ?

    - by abhilashm86
    Here's a simple function to do simple math operations, when i call this from other program using import, output i get is none. When i remove def function, everything is working fine. What's the problem with defining this function? I'm new to python. def calci(a, op, b): if op == '+': c = a + b elif op == '-': c = a-b elif op == '*': c= a*b elif op =='/': if(b == 0): print('can\'t divide') c = a/b print('value is',c) return c result = calci(12,'+', 12) print(result) nter code here

  • Should I use Python or Assembly for a super fast copy program

    - by PyNEwbie
    As a maintenance issue I need to routinely (3-5 times per year) copy a repository that is now has over 20 million files and exceeds 1.5 terabytes in total disk space. I am currently using RICHCOPY, but have tried others. RICHCOPY seems the fastest but I do not believe I am getting close to the limits of the capabilities of my XP machine. I am toying around with using what I have read in The Art of Assembly Language to write a program to copy my files. My other thought is to start learning how to multi-thread in Python to do the copies. I am toying around with the idea of doing this in Assembly because it seems interesting, but while my time is not incredibly precious it is precious enough that I am trying to get a sense of whether or not I will see significant enough gains in copy speed. I am assuming that I would but I only started really learning to program 18 months and it is still more or less a hobby. Thus I may be missing some fundamental concept of what happens with interpreted languages. Any observations or experiences would be appreciated. Note, I am not looking for any code. I have already written a basic copy program in Python 2.6 that is no slower than RICHCOPY. I am looking for some observations on which will give me more speed. Right now it takes me over 50 hours to make a copy from a disk to a Drobo and then back from the Drobo to a disk. I have a LogicCube for when I am simply duplicating a disk but sometimes I need to go from a disk to Drobo or the reverse. I am thinking that given that I can sector copy a 3/4 full 2 terabyte drive using the LogicCube in under seven hours I should be able to get close to that using Assembly, but I don't know enough to know if this is valid. (Yes, sometimes ignorance is bliss) The reason I need to speed it up is I have had two or three cycles where something has happened during copy (fifty hours is a long time to expect the world to hold still) that has caused me to have to trash the copy and start over. For example, last week the water main broke under our building and shorted out the power.

  • how to calculate a bill from several tables on mysql?

    - by Audel
    I'm using mysql to create an hotel booking system, but i am struggling a little bit to calculate the final bill. I need a SELECT command to get data from several tables and make some calculations. Basically I just need to get the 'night cost' from a table called 'room_types'. Then, use DATEDIFF function to get the difference of days between the 'checkin' and 'checkout' columns in the table 'room_booking' and multiply the difference with the night cost and display the total. These are the tables I would be using: are room_booking, room_types, booking, and room. One booking may have several room bookings, so Im looking for a table that looks something like this: +------------+------------+---------------+------------------+ | bookingid | Room price | nights stayed | total room price | +------------+------------+---------------+------------------+ | B001 | 30.00 | 4 | 120.00 | +------------+------------+---------------+------------------+ | B001 | 40.00 | 3 | 120.00 | +------------+------------+---------------+------------------+ booking id comes from table 'booking' room price from 'room_types', 'nights stayed' is calculated from the table room_booking, using the datediff command between checkin and checkout . I hope i was clear

  • Why are Python exceptions named "Error"?

    - by Elena
    Why are Python exceptions named "Error" (e.g. ZeroDivisionError, NameError, TypeError etc) and not "Exception" (e.g. ZeroDivisionException, NameException, TypeException etc). I come from a Java background and started to learn Python recently, as such this is confusing because in java there is a distinction between error and exception. Is there a difference in Python also or not? Can someone explain or point me to some documentation explaining it? Thank you!

  • Python Locking Implementation (with threading module)

    - by Matty
    This is probably a rudimentary question, but I'm new to threaded programming in Python and am not entirely sure what the correct practice is. Should I be creating a single lock object (either globally or being passed around) and using that everywhere that I need to do locking? Or, should I be creating multiple lock instances in each of the classes where I will be employing them. Take these 2 rudimentary code samples, which direction is best to go? The main difference being that a single lock instance is used in both class A and B in the second, while multiple instances are used in the first. Sample 1 class A(): def __init__(self, theList): self.theList = theList self.lock = threading.Lock() def poll(self): while True: # do some stuff that eventually needs to work with theList self.lock.acquire() try: self.theList.append(something) finally: self.lock.release() class B(threading.Thread): def __init__(self,theList): self.theList = theList self.lock = threading.Lock() self.start() def run(self): while True: # do some stuff that eventually needs to work with theList self.lock.acquire() try: self.theList.remove(something) finally: self.lock.release() if __name__ == "__main__": aList = [] for x in range(10): B(aList) A(aList).poll() Sample 2 class A(): def __init__(self, theList,lock): self.theList = theList self.lock = lock def poll(self): while True: # do some stuff that eventually needs to work with theList self.lock.acquire() try: self.theList.append(something) finally: self.lock.release() class B(threading.Thread): def __init__(self,theList,lock): self.theList = theList self.lock = lock self.start() def run(self): while True: # do some stuff that eventually needs to work with theList self.lock.acquire() try: self.theList.remove(something) finally: self.lock.release() if __name__ == "__main__": lock = threading.Lock() aList = [] for x in range(10): B(aList,lock) A(aList,lock).poll()

  • Unable to Git-push master to Github

    - by Masi
    This question is related to my problem in understanding rebase, branch and merge, and to the problem How can you commit to your github account as you have a teamMate in your remote list? I found out that other people have had the same problem. The problem seems to be related to /etc/xinet.d/. Problem: unable to push my local branch to my master branch at Github I run git push origin master I get fatal: 'origin' does not appear to be a git repository fatal: The remote end hung up unexpectedly The error message suggests me that the branch 'origin' is not in my local git repository. This way, Git stops connecting to Github. This is strange, since I have not removed the branch 'origin'. My git tree is dev * master ticgit remotes/Math/Math remotes/Math/master remotes/origin/master remotes/Masi/master How can you push your local branch to Github, while you have a teamMate's branch in your local Git? VonC's answer solves the main problem. I put a passphares to my ssh keys. I run $git push github master I get Permission denied (publickey). fatal: The remote end hung up unexpectedly It seems that I need to give the passphrase for Git somehow. How can you make Git to ask passphares?

  • Unable to connect on socket across different networks.

    - by maleki
    I am having trouble connecting my online application to others across another network. I am able to give them the hostAddress to connect when we are on the same network but when we are doing it across the internet the generated host address doesn't allow a connection, nor does using the ip address gotten from online sites such as whatismyip.com My biggest issue isn't debugging this code, because it works over intra-network but The server doesn't see attempts when we try to move to different networks. Also, the test ip I am using is 2222. InetAddress addr = InetAddress.getLocalHost(); String hostname = addr.getHostName(); System.out.println("Hostname: " + hostname); System.out.println("IP: " + addr.getHostAddress()); I display the host to the server when it is starting if (isClient) { System.out.println("Client Starting.."); clientSocket = new Socket(host, port_number); } else { System.out.println("Server Starting.."); echoServer = new ServerSocket(port_number); clientSocket = echoServer.accept(); System.out.println("Warning, Incoming Game.."); }

  • Can't find ant in the Android SDK

    - by StormShadow
    Hey all, I'm working my way through APress's Beginning Android 2 and I've made it all the way to chapter 3, where we build a skeleton app. The book tells me to compile my application by typing "ant" in the command line, but my pc doesn't know what "ant" is yet. I checked in the SDK files and it looks like it wasn't included with the Android SDK. Does anybody know where ant is? Thanks

  • Codeigniter: Using URIs with forms

The problem is, when the form is submitted, it doesn't take into account the url b/c the form submits to the function "survey", which passes data to the lib function, so things are always updated, never created. *How can I pass $method to the _submit() function correctly?!*

  • Type-conditional controls in Haskell

    - by estanford
    I'm going through the 99 Haskell problems to build my proficiency with the language. On problem 7 ("Flatten a nested list structure"), I found myself wanting to define a conditional behavior based on the type of argument passed to a function. That is, since *Main> :t 1 1 :: (Num t) => t *Main> :t [1,2] [1,2] :: (Num t) => [t] *Main> :t [[1],[2]] [[1],[2]] :: (Num t) => [[t]] (i.e. lists nested at different levels have different data types) it seems like I should be able to write a function that can read the type of the argument, and then behave accordingly. My first attempt was along these lines: listflatten l = do if (:t l) /= ((Num t) => [t]) then listflatten (foldl (++) [] l) else id l But when I try to do that, Haskell returns a parse error. Is Haskell flexible enough to allow this sort of type manipulation, do I need to find another way?

  • jQuery: Checking for length of ul and removing an li element?

    - by Legend
    I am trying to remove the last <li> element from a <ul> element only if it exceeds a particular length. For this, I am doing something like this: var selector = "#ulelement" if($(selector).children().length > threshold) { $(selector + " >:last").remove(); } I don't like the fact that I have to use the selector twice. Is there a shorter way to do this? Something like a "remove-if-length-greater-than-threshold" idea. I was thinking that maybe there is a way to do this using the live() function but I have no idea how.

  • I'm having trouble with using std::stack to retrieve the values from a recursive function.

    - by Peter Stewart
    Thanks to the help I received in this post: http://stackoverflow.com/questions/2761918/how-do-i-use-this-in-a-member-function I have a nice, concise recursive function to traverse a tree in postfix order: void Node::postfix() { if (left != __nullptr) { left->postfix(); } if (right != __nullptr) { right->postfix(); } cout<<cargo<<"\n"; return; }; Now I need to evaluate the values and operators as they are returned. My problem is how to retrieve them. I tried the std::stack: #include <stack> stack <char*> s; void Node::postfix() { if (left != __nullptr) { left->postfix(); } if (right != __nullptr) { right->postfix(); } s.push(cargo); return; }; but when I tried to access it in main() while (!s.empty()) { cout<<s.top<<"\n"; s.pop; } I got the error: 'std::stack<_Ty::top': function call missing argument list; use '&std::stack<_Ty::top' to create a pointer to member' I'm stuck. Another question to follow shortly.
