• Short brandable domain vs. long keyword domain

  - by bajki

  I need a counsel about my websites' domain. Let's say I have just bought two domains: xyz.com and xyzphotography.com. As we can see, the first one is shorter but way less meaningful than the second one. The second one contains a photography keyword but it's longer. I have only one website which is my photography portfolio. Can you advise me how to set those domains to make it all as SEO-friendly as possible? Which one should be the main one, does the rest should work on their own or have some kind of SEO-friendly redirect to the main domain?

• Wrong content for URL cache on Google

  - by user32592

  I have this website natural-track.com and when I do a cache check I get a completely different website,This is Google's cache of http://www.backpackers-planet.com/modules.php?name=Web_Links&l_op=visit&lid=3379 , unrelated to my site. I have checked with the host, they say all is well on their side. How can we fix it? The site also went off from Google Search. We are about to rebuild this site to a better professional platform but first we would like to have an idea of what happened and how to fix it.

• The Recovery: New Challenges for your Supply Chain!

  - by [email protected]

  Nearly half of CFOs are planning to reduce their inventory during the first half of 2010 in part due to supply chain improvements that allow them to hold less product, but also because of reduced demand according to Kate O'Sullivan, Sr Editor at CFO Magazine. Her view is based on this quarter's Duke University Global Business Outlook Survey. Highlights: Employment will be a drag on the economy- full-time employment to increase by 1%. Temp hiring to grow <1%, Outsourcing 4%.  70% of CFOs at SMEs say credit conditions are worse then 12 mos ago - placing strains on inventory growth Asia and China finance execs are more optimistic than their EMEA or US counterparts and expect stronger growth in capital spending with a 16% gain Source: "Slouching Towards Recovery", CFO Magazine, April 2010, pgs 19-20

• How to explain OOP concepts to a non technical person?

  - by John

  I often try to avoid telling people I'm a programmer because most of the time I end up explaining to them what that really means. When I tell them I'm programming in Java they often ask general questions about the language and how it differs from x and y. I'm also not good at explaining things because 1) I don't have that much experience in the field and 2) I really hate explaining things to non-technical people. They say that you truly understand things once you explain them to someone else, in this case how would you explain OOP terminology and concepts to a non technical person?

• Recommended method towards making custom maps for a 2d game?

  - by Qasim

  I am planning on making a 2D game, however different from my last personal projects I want this one to have enhanced graphics, with custom-designed levels. My previous 2d platformers were tile-based, in which I made a map editor for to create levels. However, I am wondering the best way to implement custom designed maps? For say, some grass is a litter higher than others, flowers here and there, cool drawings and structures along the way, etc. instead of just the same old tiles over and over again. I am thinking but I just can't grasp the idea of how to implement it. I have seen it done in other games and am interested to see how they accomplish it, but can't get my hands on some source code. :(

• Is programming too easy if compared to other fields?

  - by Shashank jain

  I have been programming since some years and I won't say its a piece of cake but in this field, you know how to do things. You can always google up resources, tutorials. There are tons of already written code to help you with - frameworks, libraries but if you compare it to other innovation fields like "Electronics". Its not too easy to get started with, the community might not be too large on the internet, getting the things right plus lets not forget there is nothing to tell you where the error might be. I have wanted many times but not be able to get into, like, building some kind of robot because I don't know how to start. So my question is that, does programming tends to be easy compared rest of the fields or is it just my intrest that makes it easy?

• Colorize with a given color a texture

  - by Pacha

  I have a texture and I want to "colorize" it with a given color, lets say cyan (#00ffff) or purple (#800080). What I want to do, is get all the pixel values from the texture, and remove the color and keep the "brightness" and "saturation" and apply to the desired color. There is a tool in GIMP to do this called Colorize (Colors -> Colorize.. while editing), I made an example below. This is will all be done in a shader (GLSL), although this is probably a general algorithm.

• Jump-start Your Mind

  - by João Angelo

  I haven’t written in a while mostly because I’ve spent my time reading what others wrote and today I’m writing purely motivated by what I just finished reading. Mindfire: Big Ideas for Curious Mind by Scott Berkun was such a pleasure to read and ended up igniting parts of my mind which I have to admit were becoming a bit numb that I felt the urge to take some time to first say thank you to the author and then recommend it to all your curious minds out there. Now, go read it… it’s time well spent.

• What threading pratice is good 90% of the time?

  - by acidzombie24

  Since my SO thread was closed i guess i can ask it here. What practice or practices are good 90% of the time when working with threading with multiple cores? Personally all i have done was share immutable classes and pass (copy) data to a queue to the destine thread. Note: This is for research and when i say 90% of the time i dont mean it is allowed to fail 10% of the time (thats ridiculous!) i mean 90% it is a good solution while the other 10% it is not so desirable due to implementation or efficiently reasons (or plainly another technique fits the problem domain a lot better).

• What does Symfony Framework offer that Zend Framework does not?

  - by Fatmuemoo

  I have professionally working with Zend Framework for about a year. No major complaints. With some modifications, it has done a good job. I'm beginning to work on a side project where I want to heavily rely on MongoDb and Doctrine. I thought it might be a good idea to broaden my horizons and learn another enterprise level framework. There seems to be a lot a buzz about Symfony. After quickly looking over the site and documentation, I must say I came away pretty underwhelmed. I'm woundering what, if anything, Symfony has to offer that Zend doesn't? What would the advantage be in choosing Symfony?

• Fullscreen windowed mode in id games

  - by Oli

  I run a TwinView, dual monitor system. I like to play games fullscreen on one of the monitors, not spanning both. With wine, this works by just setting it to desktop mode and setting the resolution to that of one screen. For OpenTTD, I used Compiz's Window Rules plugin. But I have a few native games that this doesn't work for. Today's experiment involved Prey (Doom 3 engine) but I've had similar issues with other ID engines. So in short: has anybody found a way of having Prey/OpenAreana/Doom3/etc run in windowed mode but with fullscreen decorations (that is to say, no borders and above the panel)?

• How to open a MIB file in tkmib?

  - by l0b0

  I've tried to open several MIB files in tkmib without success. For example: $ sudo apt-get install tkmib $ wget http://www.mibsearch.com/vendors/Compaq/download/CPQHLTH-MIB $ tkmib CPQHLTH-MIB Click "walk", then you should get an error message like this: setting opts getaddrinfo: CPQHLTH-MIB No address associated with hostname error:snmp_new_session: Couldn't open SNMP session at /usr/lib/perl5/SNMP.pm line 475. unable to create session at /usr/lib/perl5/SNMP.pm line 547.

• Wrong audio volume at boot

  - by skerit

  When I boot my computer and login the volume level is always way too loud. Unfortunately the only way to change it is a physical knob on my speaker. As soon as I can change the volume using my keyboard the volume immediately drops. Say the volume is at 100%, as soon as I turn the dial on my keyboard a little bit it drops to a normal level like 40% How do I get this to work in a clear way, like having it remember the audio level it was on at shutdown? Here's my audio card model: 82801JI (ICH10 Family) HD Audio Controller An Intel card on a Asus motherboard

• How does throwing an ArgumentNullException help?

  - by Scott Whitlock

  Let's say I have a method: public void DoSomething(ISomeInterface someObject) { if(someObject == null) throw new ArgumentNullException("someObject"); someObject.DoThisOrThat(); } I've been trained to believe that throwing the ArgumentNullException is "correct" but an "Object reference not set to an instance of an object" error means I have a bug. Why? I know that if I was caching the reference to someObject and using it later, then it's better to check for nullity when passed in, and fail early. However, if I'm dereferencing it on the next line, why are we supposed to do the check? It's going to throw an exception one way or the other. Edit: It just occurred to me... does the fear of the dereferenced null come from a language like C++ that doesn't check for you (i.e. it just tries to execute some method at memory location zero + method offset)?

• Is there a good book to grok C++?

  - by Paperflyer

  This question got me thinking. I would say I am a pretty experienced C++ programmer. I use it a lot at work, I had some courses on it at the university, I can understand most C++ code I find out there without problems. Other languages you can pretty much learn by using them. But every time I use a new C++ library or check out some new C++ code by someone I did not know before, I discover a new set of idioms C++ has to offer. Basically, this has lead me to believe that there is a lot of stuff in C++ that might be worth knowing but that is not easily discoverable. So, is there a good book for a somewhat experienced C++ programmer to step up the game? You know, to kind of 'get' that language the way you can 'get' Ruby or Objective-C, where everything just suddenly makes sense and you start instinctively knowing 'that C++ way of thing'?

• Is porting a Windows application to Mac worth it ?

  - by mikel

  I have a C# Windows application that sells for $35, and fairly regularly receive requests for a version for OS X too. I don't have any experience with Mac so far though, and so am not sure exactly how much work that would involve and if it would be worth it. If anyone's been in a similar position, it'd be very helpful to know: Roughly how many more (%) sales can you expect by porting to Mac ? Would you say it's worth the investment of a new Macbook Pro and the time of learning and porting to Objective-C ? Thanks in advance.

• Disable suspend / hibernate via the policykit

  - by redonath

  I am trying to run Lubuntu 12.04, but if the computer suspends I am unable to bootup again. Instead I see the bios post, the hard disk light flickers once and I have to install again (I have tried to re-install grub2). I am new to Linux and what I found that best answered my question was posted by James Henstridge. The instructions say to create disable-shutdown.pkla in etc/polkit-1/50-local.d/ but this directory does not exist, so do I create a folder titled 50-local.d in poolkit-1 or do I have to place this file elsewhere?

• Functional programming readability

  - by Jimmy Hoffa

  I'm curious about this because I recall before learning any functional languages, I thought them all horribly, awfully, terribly unreadable. Now that I know Haskell and f#, I find it takes a little longer to read less code, but that little code does far more than an equivalent amount would in an imperative language, so it feels like a net gain and I'm not extremely practiced in functional. Here's my question, I constantly hear from OOP folks that functional style is terribly unreadable. I'm curious if this is the case and I'm deluding myself, or if they took the time to learn a functional language, the whole style would no longer be more unreadable than OOP? Has anybody seen any evidence or got any anecdotes where they saw this go one way or another with frequency enough to possibly say? If writing functionally really is of lower readability than I don't want to keep using it, but I really don't know if that's the case or not..

• Is this the right strategy to convert an in-level order binary tree to a doubly linked list?

  - by Ankit Soni

  So I recently came across this question - Make a function that converts a in-level-order binary tree into a doubly linked list. Apparently, it's a common interview question. This is the strategy I had - Simply do a pre-order traversal of the tree, and instead of returning a node, return a list of nodes, in the order in which you traverse them. i.e return a list, and append the current node to the list at each point. For the base case, return the node itself when you are at a leaf. so you would say left = recursive_function(node.left) right = recursive_function(node.right) return(left.append(node.data)).append(right);` Is this the right approach?

• Photo gallery for Blogspot blog

  - by Django Reinhardt

  I don't think this is entirely possible, but here we go: I have a friend who has a Blogspot blog. He has posts with text, posts with videos and posts with photos... and he was wondering if there's any way to turn the posts which are just photos into a thumbnail gallery screen on his blog. So for example, let's say he has 20 photo posts on his blog with the label Skiing Holiday 2009 (horrible example, I know). Is there a way of having a post created for his blog that displays those photos as thumbnails, linking through to their full size versions? I just don't think it's possible, but I'm really hoping someone will be able to offer a solution (or even a place where I could find a solution). Thanks a lot.

• System Error Report /usr/bin/Xorg

  - by jimirings

  I have recently begun getting a System Error Report message when I start up my computer. I haven't installed anything recently other than the usual updates or done anything else out of the ordinary. The details for the report just say "/usr/bin/Xorg". It doesn't seem to be causing me any problems beyond the annoying error message. I saw these questions regarding this problem: System Error Report - Xorg How do I enable or disable Apport? That's all dandy for getting the message to go away, but I'd rather fix the problem. Any ideas how I can make that happen? I'm running Ubuntu 12.04 on a Toshiba NB505. I am, of course, happy to provide any other relevant information that may be needed. Thanks in advance.

• What would be the best approach to make revisions of user content?

  - by Kevin Simper

  I have searched and could not find any information about it. What is the best approach to storing revisions? I have a website where the user can write a document which can be fairly long (200-300 lines). How do you determine when to make a revision? Is it not a scalable solution to make a new one whenever the save, because that would be useless to the user when the want to look back, and it would require quite a lot of space. You could use time and say for every 15 minute they are working on it there would be a revision, but that would sometimes be nothing or the whole document have completely changed. I could make a diff from the previous revision, and compare by line and look at how many percent of the lines have been changed. What are other doing revisions?

• How do you name your personal libraries?

  - by Mehrdad

  I'm pretty bad with naming things. The only name I can every generically come up with is 'helper'. Say, if I have a header file that contains helping functions for manipulating paths, I tend to put it inside my "helper" directory and call it "path-helper.hpp" or something like that. Obviouslly, that's a bad naming convention. :) I want to have a consistent naming scheme for my folder (and namespace) which I can use to always refer to my own headers and libraries, but I have trouble finding names that are easy to type or remember (like boost)... so I end up calling some of them "helper" or "stdext" or whatnot, which isn't a great idea. How do you find names for your libraries that are easy to remember and easy to type, and which aren't too generic (like "helper" or "std" or "stdext" or the like)? Any suggestions on how to go about doing this?
