• Google indexing wrong domain that does not work

  - by user174117

  Can anyone tell me why Google indexes a site http://0.3c.7aae.static.theplanet.com instead of the actual domain name (my domain was registered with webmaster tools). The aforementioned link was linking to my site, but has now become a broken link. Initially I tried 301 directs, but nothing worked. The hosting company cannot explain why. Leaving me wondering what to do? Any guidance would be appreciated. Thks

• Tkinter on Ubuntu 14.04 seems not to work

  I receive following Traceback: Traceback (most recent call last): File "tkinter_basic_frame.py", line 4, in <module> from Tkinter import Tk, Frame, BOTH File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 42, in raise ImportError, str(msg) + ', please install the python-tk package' ImportError: No module named _tkinter, please install the python-tk package This is the demoscript I'm trying to run: #!/usr/bin/python # -*- coding: utf-8 -*- from Tkinter import Tk, Frame, BOTH class Example(Frame): def __init__(self, parent): Frame.__init__(self, parent, background="white") self.parent = parent self.initUI() def initUI(self): self.parent.title("Simple") self.pack(fill=BOTH, expand=1) def main(): root = Tk() root.geometry("250x150+300+300") app = Example(root) root.mainloop() if __name__ == '__main__': main() From my knowledge Tkinter should be included in Python 2.7. Why do I receive the traceback? Doesn't ubuntu contain the standard-python-distribution? This is solved. I had to install it manually in synaptic (got the hint in the meantime from another forum), see here: Wikipedia says: "Tkinter is a Python binding to the Tk GUI toolkit. It is the standard Python interface to the Tk GUI toolkit1 and is Python's de facto standard GUI,2 and is included with the standard Windows and Mac OS X install of Python." - Not good, that it isn't included in Ubuntu as well.

• I can't get click and drag to work with my Wacom Bamboo P&T

  - by Magnus Hoff

  I get my Wacom Bamboo Pen & Touch apparently working (By using Martin Owens' PPA), but whenever I try to click and drag something -- for example to move a window -- it will only register as a click. In other words: The "button up" event is generated right after the "button down" event no matter how long I hold it in. This is the same whether I use the tip of the pen, the buttons on the pen or the buttons on the pad. However: Clicking and dragging works perfectly in the login-screen, both before logging in for the first time and after logging out.

• Getting PHP to work with apache to run .php files through browser [closed]

  - by Kevin Duke

  I have VPS running Debian 5.0 (I think) and I would like to get it to run PHP files. I was told it needed to be configured with Apache. I tried entering the command apt-get install apache2 php5 libapache2-mod-php5. But there was no change. Console output: http://pastebin.com/sVMWq6mA This is everything in my /etc/apache2/mods-enabled: http://img35.imageshack.us/img35/6474/modsb.jpg My webserver can be accessed here: http://206.217.223.136/test/ In my test.php file I have the code : <?php phpinfo(); ?> but instead of displaying the page, it tries to download it. How can I fix this?

• How does key-based caching work?

  - by Dominic Santos

  I recently read an article on the 37Signals blog and I'm left wondering how it is that they get the cache key. It's all well and good having a cache key that includes the object's timestamp (this means that when you update the object the cache will be invalidated); but how do you then use the cache key in a template without causing a DB hit for the very object that you are trying to fetch from the cache. Specifically, how does this affect One to Many relations where you are rendering a Post's Comments for example. Example in Django: {% for comment in post.comments.all %} {% cache comment.pk comment.modified %} <p>{{ post.body }}</p> {% endcache %} {% endfor %} Is caching in Rails different to just requests to memcached for example (I know that they convert your cache key to something different). Do they also cache the cache key?

• Setting up a common perl/cpan environment

  - by zedoo

  Hi, so I'm having a lot of fun with Perl at home for some time now. How much more difficult do things get when you develop Perl modules (In my case it's mostly catalyst) in a team? How do we make sure we all got the same development environment (Perl/Module versions)? Simply by keeping up to date with CPAN? Do some teams setup their 'private' CPANs?

• Amazon how does their remarkable search work?

  - by JonH

  We are working on a fairly large CRM system /knowledge management system in asp.net. The db is SQL server and is growing in size based on all the various relationships. Upper management keeps asking us to implement search much like amazon does. Right from there search you can specify to search certain objects like outdoor equipment, clothing, etc. and you can even select all. I keep mentioning to upper management that we need to define the various fields to search on. Their response is all fields...they probably look at the search and assume that it is so simple. I'm the guy who has to say hold on guys we are talking about amazon here. My question is how can amazon run a search on an "all" category. Also one of the things management here likes is the dynamic filters. For instance, searching robot brings up filters specific to a robot toy. How can I put management in check and at least come up with search functionality that works like amazon. We are using asp.net, SQL server 2008 and jquery.

• Flash animations doesn't work

  - by sosen

  I have a following problem: I have Ubuntu 12.04 installed on my Athlon 1800+ + 1 GB RAM + Nvidia Geforce4 MMX 440 (pretty old configuration) and everything works just fine except Flash Player in my Web browser (tried Firefox and Chromium). Instead of movie/animation, I get blank space. I updated my system via update manager, checked the plugins (everything OK), installed and updated flash player one more time, installed Ubuntu restricted extras, tried Firefox's Flash Aid, even tried Youtube Html 5 (still the same result)... Please, help me! I enjoy working with Linux and Ubuntu is the first that works for me well (after Open Suse and Fedora) but I have no idea what is wrong now...

• How does a website like Mathway work?

  - by Bob

  I recently found a website called Mathway Basically, it works by allowing you to choose your "level of math" (which it uses to determine what tools it should provide to you) and then allows you to input a math problem which it then solves for you, and gives you detailed solutions (you have to try it, it's really cool). I was wondering how it worked on two levels. First off, how would they parse the math problem (and all the sometimes foreign mathematical operators)? How do they get from text to numbers, variables, and operators? Second, how do they generate the explanations? While you have to pay for the detailed solutions (which are explanations of how they solved the problem), I've seen their preview screenshots, and it looks very detailed. The explanations are given in full, accurate sentences. How would they generate something like that?

• Work Item Traceability in TFS 2010

  - by Sam Patrick

  I have created a Windows Form project (VS solution) under a TFS 2010 project. I may eventually add more solutions to the TFS project. My question: Can we create a Use Case WIT for a specific solution within a TFS project? Furthermore, is it possible to create a "traceability matrix" that starts at the Use Case level and goes down to the the code level (at least the namespace level) of that particular VS solution?

• Macbook Pro 13" Retina (10,2): Keyboard and Touchpad don't work

  - by Dirk

  I'm dealing with Ubuntu since about 5 years and installed it on several laptops. Now I'm stuck when trying to install Ubuntu 12.04.1 on a brand new Macbook Pro 13" Retina (10,2). I sucessfully can start Ubuntu from an USB stick, the Ubuntu desktop is visible, a mouse cursor is visible. But there is no respond to keyboard or touchpad input. So I cannot really install Ubuntu on the Macbook. The details of my approach: Prepare an empty USB stick Download "ISO 2 USB EFI Booter for Mac" and copy the file bootX64.efi to the USB drive as /efi/boot/bootX64.efi. Download Ubuntu 12.04.1 Desktop for Mac from http://cdimage.ubuntu.com/releases/1-amd64+mac.iso and copy the iso the USB drive as /efi/boot/boot.iso Put the USB stick into the Macbook Press and hold the "alt" button while switching the Macbook on Select "EFI Boot" from the boot menu that appears and press the Return / Enter key Immediately a black terminal screen appears with the headline "Welcome to the Ubuntu ISO << - EFI booter". 30 seconds later the familiar Ubuntu startup graphics screen is showing. Further 20 seconds later Ubuntu has started and the desktop is visible - in wonderfully fine resolution Now the computer does not respond to any actions on the touchpad nor the keyboard Who did install Ubuntu on this Macbook Pro 13" Retina (10,2) successfully? On this site https://help.ubuntu.com/community/MacBookPro this unit is not listed yet, anyway. Any help would be greatly appreciated! Dirk

• How does this game loop actually work?

  - by Nicolai

  I read this playfulJS post, about ray-casting: http://www.playfuljs.com/a-first-person-engine-in-265-lines/ It looks really interested, so I decided to look at his javascript. I am no expert in javascript, so I quickly got lost. It's the game loop "object" that really gets me. I simply don't understand how it works. From the code: function GameLoop() { this.frame = this.frame.bind(this); this.lastTime = 0; this.callback = function() {}; } GameLoop.prototype.start = function(callback) { this.callback = callback; requestAnimationFrame(this.frame); }; GameLoop.prototype.frame = function(time) { var seconds = (time - this.lastTime) / 1000; this.lastTime = time; if (seconds < 0.2) this.callback(seconds); requestAnimationFrame(this.frame); }; var loop = new GameLoop(); loop.start(function frame(seconds) { map.update(seconds); player.update(controls.states, map, seconds); camera.render(player, map); }); Now, what really confuses me here, is this bind stuff and how this actually loops. I am guessing, that if less than 0.2 seconds have passed, since the last time the loop was run, it simply goes back to re-check the time. If more than 0.2 seconds have passed, it leaves the frame function, and executes the 3 lines in the loop. But, if this is true, then how does the loop.start() get called again? And what on earth is the meaning of this.frame = this.frame.bind(this);? I've looked up prototypes bind() but I really don't understand it.

• Quoting people for website dev. work

  - by Jason

  Hi All, I have recently given some quotes to a few people. And I need some advice about how things should be done... Q1: I've seen, heard of and read about a lot of developers using free resource sites online to obtain free Privacy Policy, Disclaimers etc for their/customers websites. A customer I quoted the other day expected me to write/get a disclaimer for their site. Who in their right mind would expect a document like that from a Web Developer? I just told them that they need to sort that stuff out themselves with a Lawyer or something, and then to send it to me so I can paste it on a webpage for them. Q2: If you're charging per hour, and you estimate that the project would take 1week to finish (including testing/releasing), but you soon realise that you'll require more time, do you RE-quote them? Or do you just finish off the site at the original quote price? Q3: How do you figure out how much you will charge your customers? Do you charge per-feature, or per hour, or per day, or all of the above? Thanks :)

• How Microwave Ovens Work [Video]

  - by Jason Fitzpatrick

  In this informative how-it-works video, we’re treated to a peek inside the common microwave and the science behind the magnetron that powers it. Bill details how a microwave oven heats food. He describes how the microwave vacuum tube, called a magnetron, generates radio frequencies that cause the water in food to rotate back and forth. He shows the standing wave inside the oven, and notes how you can measure the wavelength with melted cheese. He concludes by describing how a magnetron generates radio waves.

  I've found that after upgrading to 11.10 (32 bit), I can no longer watch streaming flash video on sites such as Ustream or Justin.tv. I've spent the last several hours installing this package and uninstalling that package, and purging everything flash-related and starting over, to no avail. I was curious if anybody else has run into similar issues and found a fix. I'm running an NVIDIA card, and I've tried both sets of drivers available.

• Make Google Plus One only work for the domain and not the path [closed]

  - by Saeed Neamati

  Possible Duplicate: Make Google +1 button +1 a specific URL rather than the URL it's on? I'm creating an image sharing website, and since it's going to have many thousand links, then it's almost impossible to put a Google Plus One button in my site. Plus one is an indication of site's popularity and trust. You follow a link in SERP, because you see that somebody that you know has already plused one that link. So, you trust that link and click it. The more plus a page get, the more trustworthy it becomes. Sites which has simple static pages can get many plus ones, but sites like mine (dynamic sites with thousands of links) can't aggregate plus ones in one page. Is there any way to tell Google that I only want the Plus Ones to be counted for the domain only, and not for the path? In other words, how can I transfer a plus one given to the http://example.com/tag1-tag2/2525 to plus ones given to the http://example.com? Is it possible at all?
