• Do first impressions really count?

  - by Matt

  So, i am currently writing something up for a college class. Problem is everything is hypothetical. I need some proof. I believe a first impression on a website is imperative so that people actually use it and in my case, buy your product or services as well. Basically I'm wondering has there been any studies that shows how a better web design will increase revenue for any kind of services? I don't just mean selling products like a T-shirt, but labor services as well. If someone wanted their computer fixed and searched for companies that can do so, will a first impression on the website help them make their decision to use your company? Are there any studies like this? White papers maybe? Thanks!

• TCO Comparison: Oracle Exadata vs IBM P-Series

  - by Javier Puerta

  Cost Comparison for Business Decision-makersOracle Exadata Database Machine vs. IBM Power SystemsHow to Weigh a Purchase DecisionOctober 2012 Download full report here In this research-based  white paper conducted at the request of Oracle, The FactPoint Group compares the cost of ownership of the Oracle Exadata engineered system to a traditional build-your-own (BYO) solution, in this case an IBM Power 770 (P770) with SAN storage.  The IBM P770 was chosen given it is IBM’s current most popular model, based on FactPoint primary and secondary research and IBM claims, and because at least one of the interviewed customers had specifically migrated from a P770 to Exadata, affording us a more specific data point for comparison. This research found that Oracle Exadata: Can be deployed more quickly and easily requiring 59% fewer man-hours than a traditional IBM Power Systems solution. Delivers dramatically higher performance typically up to 12X improvement, as described by customers, over their prior solution.  Requires 40% fewer systems administrator hours to maintain and operate annually, including quicker support calls because of less finger-pointing and faster service with a single vendor.  Will become even easier to operate over time as users become more proficient and organize around the benefits of integrated infrastructure. Supplies a highly available, highly scalable and robust solution that results in reserve capacity that make Exadata easier for IT to operate because IT administrators can manage proactively, not reactively.  Overall, Exadata operations and maintenance keep IT administrators from “living on the edge.”  And it’s pre-engineered for long-term growth. Finally, compared to IBM Power Systems hardware, Exadata is a bargain from a total cost of ownership perspective:  Over three years, the IBM hardware running Oracle Database cost 31% more in TCO than Exadata.

• What's the location of a personal 'gtkrc' file in Ubuntu 12.04?

  - by Kevin Perez

  Good day everyone! I am currently writting a software that makes easy to change default cursor theme with a few clicks. At this point it works well, but applications like Firefox or Lazarus IDE remain with the DMZ-White cursor, everything else is ok. I noticed that when I change the default cursor using my software, and later change the 'personalized' cursor theme using Ubuntu Tweak, it does the job, and the new theme is now applied everywhere. So, what file is need to modify in order to change 'personal' cursor theme? If my software can do this, that would be great! I found that 'gtkrc' is a file where settings of GTK+ are stored. I searched in my home folder but I can't find yet. Can you help me with this, noble people of Ubuntu? :)

• OUYA and Unity set up problems

  - by Atkobeau

  I'm having trouble with the Unity / OUYA plugin. I'm using Unity 4 with the latest update on a Windows 7 machine. When I open the starter kit and try to compile the plugin I get the following error: Picked up _JAVA_OPTIONS: -Xmx512M And if I try to Build and Run I get this error: Error building Player: ArgumentException: Illegal characters in path. I'm stumped, I've gone through lots of forum posts here and on stackoverflow and I can't seem to resolve it.

• How to start a high school Java/Android development club for 13-17 year olds

  - by PaulHurleyuk

  My wife is a high school maths teacher, and is considering starting a programming club for 13-17 years olds who show an interest. Their interest seems to be around Apps and Android which I have little experience of. The kids would be (presumably) interested in programming, and have a fairly high level of computing knowledge. We would provide them with resources and some knowledge, but hopefully a lot would be self guided. I'm hoping stack overflow'ers can provide some tips or starting points. Specific things I think I'll need are; A development Environment; Currently I'm looking towards Java and Android, developed in Eclipse, probably installed on donated older hardware Some initial direction; There seem to be a plethora or 'start android' tutorials, so some recommendations for good ones are valuable, as are recommended paper books A Target; Some final project they should be shooting for A Route; This is where I'm most stuck, how to lead them through the required Java concepts and learning they would need Some related questions already out there Language+IDE for teaching high school students? Teaching "web design/development" to high-school home-school group. Good sources? How can I bootstrap a software development community at my school?

• Stuck on Ubuntu startup screen (5 orange bullets)

  - by psyboy14

  I recently download Ubuntu 12.04 LTS onto my Macbook Pro 5-5. Everything worked seamlessly, save for the brightness control. I couldn't change the screen brightness from the hardware buttons, nor from the system preferences. To fix it, I used the instructions here: MacbookPro 5-5 LCD Brightness Control At #2, I restarted my laptop, only to see that it went straight to the Ubuntu Startup Screen, with the 5 orange dots (Usually they all startoff white, then turn orange to indicate progress). From there, I tried controlling the brightness from the keyboard, and it worked, but sadly, my computer is still stuck on the loading screen. (Yes, I have tried manually restarting it) Could you please help? Thank you in advance

• How can you remove Unity from Ubuntu Netbook Edition

  - by Brad

  In previous versions of Netbook Remix I was able to disable the netbook-launcher and just have a blank desktop. I liked the speed of the Netbook version but not the interface, this worked well for me. However, now with 10.10 and Unity I'm having trouble doing a similar thing. I tried removing netbook-launcher from the startup and tried uninstalling unity. The best result I got was a black desktop with a panel and a non configurable blank white background. Is Unity soo integrated into this version that I will have to just go with the default ubuntu installation?? In the past the default version has been slower then the Netbook version without the interface. Thanks.

• Why does Live-USB boot freeze at the moving dots?

  - by Caleb

  I am currently trying to boot into Ubuntu 12.04 x86 using a USB. I used Untetbootin to do all that boot crap and what not. But for some reason Ubuntu wont load pass that screen with the dots and the purple background. What happens is the dots all light up once, then they go back to white then they all light up at the same time and then it just gets stuck there. Ive even tried using an x64 copy (since my CPU supports it) but have no luck with that either. Ive even tried different DISTRIBUTIONS of Linux and all have failed with loading. Please help

• Antenna Aligner part 2: Finding the right direction

  - by Chris George

  Last time I managed to get "my first app(tm)" built, published and running on my iPhone. This was really cool, a piece of my code running on my very own device. Ok, so I'm easily pleased! The next challenge was actually trying to determine what it was I wanted this app to do, and how to do it. Reverting back to good old paper and pen, I started sketching out designs for the app. I knew I wanted it to get a list of transmitters, then clicking on a transmitter would display a compass type view, with an arrow pointing the right way. I figured there would not be much point in continuing until I know I could do the graphical part of the project, i.e. the rotating compass, so armed with that reasoning (plus the fact I just wanted to get on and code!), I once again dived into visual studio. Using my friend (google) I found some example code for getting the compass data from the phone using the PhoneGap framework. // onSuccess: Get the current heading // function onSuccess(heading) {    alert('Heading: ' + heading); } navigator.compass.getCurrentHeading(onSuccess, onError); Using the ripple mobile emulator this showed that it was successfully getting the compass heading. But it didn't work when uploaded to my phone. It turns out that the examples I had been looking at were for PhoneGap 1.0, and Nomad uses PhoneGap 1.4.1. In 1.4.1, getCurrentHeading provides a compass object to onSuccess, not just a numeric value, so the code now looks like // onSuccess: Get the current magnetic heading // function onSuccess(heading) {    alert('Heading: ' + heading.magneticHeading); }; navigator.compass.getCurrentHeading(onSuccess, onError); So the lesson learnt from this... read the documentation for the version you are actually using! This does, however, lead to compatibility problems with ripple as it only supports 1.0 which is a real pain. I hope that the ripple system is updated sometime soon.

• Generating Landed Cost Management Charges using Custom Pricing Attributes

  - by ChristineS-Oracle

  Learn how to incorporate Custom Pricing Attributes into Landed Cost Management through a new whitepaper.  The new application, Landed Cost Management (LCM), enables exact shipment charges to be applied to incoming receipts. These charges are calculated using the Freight and Special Charges functionality from Advanced Pricing within the Pricing Transaction Entity of “Purchasing”.Advanced Pricing is very flexible in that custom attributes can be defined to derive specific charges. The way that Landed Cost Management builds these attributes is different from the processing for Advanced Pricing with Purchasing.The whitepaper can be downloaded from document Oracle Advanced Pricing White Papers, Doc ID 136687.1.

• Most effective work habit for coding? [on hold]

  - by Cris

  Working on a big solo project (~15,000 LOC), I am encountering the following phenomenon: I seem to work best when I program in short bursts of 10-15 minutes. Right now I am working on a section which is a complete first time for me architecturally and if I have any architectural issues that emerge when doing the implementation, I seem to be able to best serve these by taking a total break. Then, later, sketching out the ideas on some paper. And when I feel I have sufficient clarity, then going back to code. This iterates until that architectural issue for that section is resolved. This seems quite counter intuitive: that I can progress more quickly by coding less, and taking more breaks. I am nearing the end of the sections which are "first times" for me, and about to dive into stuff which I am much more familiar and am wondering if this counter intuitive efficiency will continue. So my question is: even for regular coding of sections one is familiar with, which don't require constant re-clarification of the best architecture, is more progress to be attained by taking more breaks and coding in bursts?

• How to play WMV files?

  - by Isaiah Bugarin

  I tried playing a WMV file in VLC and it told me something along the lines of Unable to play WMV3 files. Unfortunately there is no way for you to fix this. When I try to open the same file in MPlayer, it tells me an Internal data stream error occurred. I finally got it to start playing in KPlayer, but it is really sketchy; it's black and white and there's a few random blue lines down the middle of the video. So is there any support for WMV3 files? P.S. the same WMV file plays fine on my PC. A different WMV file plays on Ubuntu fine.

• Cinnamon Settings blank after update

  - by Seth Balmore

  Using Ubuntu 12.04 with the cinnamon desktop, I installed the most recent updates and now when I open "System Settings" the entire window appears as a blank white screen. The headers for APPEARANCE, PREFERENCES, and HARDWARE are present, but the usual icons for *Background, *Hot Corners, *Printers, etc. are no longer visible. Some of these settings can still be altered via the terminal: cinnamon-settings backgrounds cinnamon-settings applets cinnamon-settings mouse and touchpad But other commands, such as cinnamon-settings hot corners are met with an error. This is obviously a problem with cinnamon, so I just want to bring it to attention and find out when they plan on fixing the bug. A workaround can be found on the web, but it seems way to risky to rely on.

• How do I draw video frames onto the screen permanently using XNA?

  - by izb

  I have an app that plays back a video and draws the video onto the screen at a moving position. When I run the app, the video moves around the screen as it plays. Here is my Draw method... protected override void Draw(GameTime gameTime) { Texture2D videoTexture = null; if (player.State != MediaState.Stopped) videoTexture = player.GetTexture(); if (videoTexture != null) { spriteBatch.Begin(); spriteBatch.Draw( videoTexture, new Rectangle(x++, 0, 400, 300), /* Where X is a class member */ Color.White); spriteBatch.End(); } base.Draw(gameTime); } The video moves horizontally acros the screen. This is not exactly as I expected since I have no lines of code that clear the screen. My question is why does it not leave a trail behind? Also, how would I make it leave a trail behind?

Now I want to show the path where the body will go when the user have touched. If you have played Angry Birds or Basket Ball Shoot or any other which have projectile motion with a path shown you will get my point. I want to show the white dots which are shown in those games.

• Boot-up hangs unless I manually select the kernel in the bootloader

  - by The Photon

  In my stock Ubuntu install (forgot which critter its named for, about one year old), I am able to boot up normally only if I manually select the kernel in the bootloader (Grub). If I step away and it boots from the default, the system will hang with the word "Ubuntu" on a graphics screen and a few white/red blinking dots beneath it. umb@digdug:~$ uname -a Linux digdug 2.6.32-42-generic #95-Ubuntu SMP Wed Jul 25 15:57:54 UTC 2012 i686 GNU/Linux Synaptics says I have 'grub-pc' version 1.98-1ubuntu-13 installed. My grub.cfg does have default="0" which I would expect to make the default be the first kernel shown in the selection screen. The system is a laptop with an i7 processor, and I have had trouble with some kernels not being able to boot at all in the past, and power management is not working perfectly, but I have not had problems booting the latest kernel (2.6.32-42) if I select it manually in Grub. Any idea what is going on here and how can I fix it so that I can re-boot unattended?

• Converting a bounded knapsack problem to 0/1 knapsack problem

  - by Ants

  I ran across a problem where goal was to use dynamic programming (instead of other approaches). There is a distance to be spanned, and a set of cables of different lengths. What is the minimum number of cables needed to span the distance exactly? To me this looked like a knapsack problem, but since there could be multiples of a particular length, it was a bounded knapsack problem, rather than a 0/1 knapsack problem. (Treat the value of each item to be its weight.) Taking the naive approach (and not caring about the expansion of the search space), the method I used to convert the bounded knapsack problem into a 0/1 knapsack problem, was simply break up the multiples into singles and apply the well-known dynamic programming algorithm. Unfortunately, this leads to sub-optimal results. For example, given cables: 1 x 10ft, 1 x 7ft, 1 x 6ft, 5 x 3ft, 6 x 2ft, 7 x 1ft If the target span is 13ft, the DP algorithm picks 7+6 to span the distance. A greedy algorithm would have picked 10+3, but it's a tie for minimum number of cables. The problem arises, when trying to span 15ft. The DP algorithm ended up picking 6+3+3+3 to get 4 cables, while the greedy algorithm correctly picks 10+3+2 for only 3 cables. Anyway, doing some light scanning of converting bounded to 0/1, it seems like the well-known approach to convert multiple items to { p, 2p, 4p ... }. My question is how does this conversion work if p+2p+4p does not add up to the number of multiple items. For example: I have 5 3ft cables. I can't very well add { 3, 2x3, 4x3 } because 3+2x3+4x3 5x3. Should I add { 3, 4x3 } instead? [I'm currently trying to grok the "Oregon Trail Knapsack Problem" paper, but it currently looks like the approach used there is not dynamic programming.]
