• Decrease mouse sensitivity below the standard limit.

  - by Bruce Connor

  I've got a USB mouse attached to my Ubuntu notebook. This mouse is (unfortunately) really sensitive, and so it sometimes gets hard to hit small icons with the mouse pointer. This is really a hardware issue, it's not a bug and it's not Ubuntu's/gnome's fault. Still, I would very much like to this issue through software (solving through hardware would imply buying a new mouse). Back in Windows, if I set the sensitivity as really low it was comfortable enough. In Ubuntu, even the lowest sensitivity and acceleration available (in the SystemPrerencesMouse menu) is still frustrating. How can I decrease it below the default minimum? I tried xset, but it seems xset only deals with acceleration and threshold, but not actual sensitivity.

• 0.00006103515625 GB of RAM. Is .NET MicroFramework part of Windows CE?

  - by Rocket Surgeon

  The .NET MicroFramework claims to work on 64K RAM and has list of compatible targets vendors. At the same time, same vendors who ship hardware and create Board Support Packages (vendors like Adeneo) keep releasing something named Windows 7 CE BSP for the same hardware targets. Obviously the OS as heavy as WinCE needs more than 64K RAM. So, somehow .NET MicroFramework is relevant to WinCE, but how ? Is it part of bigger OS or is it base of it, or are both mutually exclusive ? Background: 0.00006103515625 GByte of RAM is same as 64Kbyte of RAM. I am looking for possiblity to use Microsoft development tools for small target like BeagleBone. http://www.adeneo-embedded.com/About-Us/News/Release-of-TI-BeagleBone Nice. Now .. where is a MicroFramework for the same beaglebone ? Is it inside the released pile ?

• Clicks counting and crawler bots

  - by Dennis

  I am currently running a small affiliate-program for Facebook users. We use an auto-poster to publish links to fan pages. Every hit is stored in our database and we have included a 24 hour reload block for the IP-addresses. My problem right now is that the PHP script also stores every hit from all the bots that crawls my website. Now I was thinking to block those bots with the robots.txt of my website but I am afraid that this will have a negative effect on my AdSense ads. Does anybody have an idea for me how to work this out?

• Community to discuss project ideas

  - by Auxiliary

  Although I already predict the down votes but the question has stuck in my throat for a while now. I think this has happened to many of us. Sometimes we find a great idea for a project and obviously think this is THE GREATEST idea ever but then one of the following things will happen: The project is a small one, so you might actually give it a try and see how it goes. The project is a big one, even a risk, and you just need a good programmer's community that you could just discuss your idea with them and see what they say and even get some help to make it happen. And there's always the possibility of others stealing your idea which is really bad. So could anyone suggest an online community or place or even method of talking about ideas and the ways of developing them? and do you think it's a good thing to tell others about your idea?

• ARM TechCON 2013 presentation: Java SE 8 Compact Profiles

  - by hinkmond

  I'll be giving a technical session presentation at ARM TechCON 2013 this Wed. 10/30 @ 11:30am. So if you are in Santa Clara, Calif. come over to the conference and hear me present on this fun-filled topic! See: Java SE 8 Compact Profiles Here's a quote: Java SE 8 has a new Compact Profiles feature that allows for three new specification–compliant subsets of Java SE 8 APIs. Compact Profiles will enable the creation of Java SE 8 runtimes that support configurations that previously were possible only with the CDC version of J2ME... It's an important topic in today's mad, mad world of Embedded Development. You never want to develop in Java for small devices with your Compact Profiles. It's just not what you'd want! Hinkmond

• Configuration server problem after changing /tmp mountpoint: how to solve?

  - by Aron Rotteveel

  I created a new partition on my hard drive because my /tmp partition was too small. I changed the mountpoint in /etc/fstab and rebooted. Every time I reboot, I get the following error message at the login screen: There is a problem with the configuration server. (/usr/lib/libgconf2-4/gconf-sanity-check-2 exited with status 256) When I log in, /tmp is mounted correctly and everything seems to work fine. When I reboot, the error shows again. When I change the /tmp mountpoint back to the old partition, the error message disappears. What could be causing this and how can I solve this issue?

• Is gettext appropriate for internationalizing user help documentation?

  - by Richard JP Le Guen

  On my project, we have po files to internationalize/translate various labels, error messages, button-text etc. We also have separate po files for the entirety of our help documentation, which is included in the product. Is this an appropriate use of gettext - putting entire documents in po files as opposed to just labels and messages? The format has been made all the more complicated because sometimes (for tooltips or "what's this" icons) only a small part of the help doc is needed, resulting in single phrases/paragraphs being entries in the po file, which are then concatenated together when the user views the help... making the actual act of translation challenging. Is there a better way to internationalize end user help documentation?

• URL structure for content that is updated daily

  - by Brendon

  A small, simple site I am working on displays a single page with the day's best offers on it. The user is able to move back and forth between previous days. Which of the following URL structures works best? Structure 1 /index.html -- today's best offers /2013-06-29.html -- yesterday's best offers, etc. Structure 2 /index.html -- 302 redirects to /2013-06-30.html (or whatever today is) /2013-06-30.html -- today's best offers /2013-06-29.html -- yesterday's best offers, etc. I quite like structure 2 from the user's point of view (they can share content easily), but I am a bit concerned about updating the redirect from /index.html every single day -- would this perhaps have unintended SEO consequences?

• Why should I adopt MVC?

  - by Andrew

  I decided to get my hands wet and got the YII framework for PHP. I created my first application, then created new controller, model and view. Connected to database, got my record passed from controller to the view and printed the hello world. I am confused now. If I have to do the same thing for each page, this seems like a nightmare to me. In each controller I have to do a lot of same operations - declare variables, and pass them to views. I also need to create models for each page and this is all confusing to me. In my idea the main goal of development is to avoid duplication, but what I see here is lots and lots of duplicated code. Please advise and clarify. Maybe you could suggest a good reading about MVC and coding patterns and best practices in MVC. Because so far, it takes much more time to create a small site using MVC than using my own programming schema.

• OpenGL ES 1 Pixel Error?

  - by Beginner001

  I am developing a game on android using OpenGL ES 1.0 for Android OS. It is a 2d game using a simple Orthographic projection and textures for the sprites. One of these textures has a small line (it looks like 1 pixel) all the way across the top that has the same colors as the bottom 1-pixel line of the texture. It is almost as if the bottom line of the image raster was copied and pasted as the top line as well. Is anyone familiar with this type of error? What could the problem be?

• If PHP websites represnt 70% of websites in my country then should I learn it?

  - by Fadi Tiwari

  In my country most of the sites are built using PHP and MySQL. Half of those sites use vbulletin and Wordpress. When it comes to companies, ministries and universities they use ASP.NET. I am not sure what should I learn to get more money as freelacer? Should I learn ASP.NET and focus my area to build companies and universities' sites? (And the question if they will know me one day and ask me to build any of their sites or not?) Or should I learn PHP and focus my business on people's sites and maybe some small formal sites? Which option will give me more money?

• What would you think of a job based on mostly doing the proof of concept?

  - by davsan

  I'm working as a developer in a small software company whose main job is interfacing between separate applications, like between a telephony system and an environment control system, between IP TVs and hospitality systems, etc...And it seems like I am the candidate for a new job title in the company, as the person who does the proof of concept of a new interfacing project and does some R&D for prototyping. What do you think the pros and cons of such a job would be, considering mainly the individual progress/regress of a person as a software engineer? And what aspects would you consider essential in a person to put him/her in such a job position?

• Fonts totally unreadable

  - by Toni

  I've just upgraded from 10.04 to 10.10 and my fonts are all just small rectangles with nothing in them. They are completely unreadable. EVEN THE FONTS IN THE TERMINAL. Thank god the fonts in my Chromium were ok, because I wouldn't be able to find this site or write this message. So far I've tried to use the Appearance - Font thing and it doesn't work. For some reason there was an error with the fonts during the installation. Please help, this is an utter nightmare...

• Pay for Graphic Designer vs Programmer

  - by FrankSinatra

  In a corporate web-design setup, who typically makes more per hour, the graphic designer or the programmer? By graphic designer, I mean somebody who builds mockups probably in photoshop, selects font-styles, colors, etc. Most things layout-wise are near pixel-perfect, but likely after the initial implementation by the programmer, there will be a lot of small changes directed by the graphic designer. By programmer, I mean somebody who is coding the CSS, the HTML, and light backend support, probably in PHP. The programmer will attempt to duplicate the mockups given the limitations of the medium, and consult with the graphic designer afterwards on what changes are tangible and which are not. Both probably have an undergraduate degree from a respected four-year institution.

• SEO blog Indexing: wordpress.com subdomain vs a registered domain?

  - by rumspringa00

  I've used WordPress for a few of my client's sites, mostly small businesses and eCommerce sites. I have found through Google Analytics as well as the All in One Webmaster plugin that when it comes to social media, using WordPress is a surefire way of getting your site indexed by Google and occasionally Bing and Yahoo. Since I am a heavy WP user, I'd like to contribute by registering a dot WordPress domain for my portfolio. When using a WP installation concurrently with a WP domain, e.g. myportfolio.wordpress.com, will the site be more or less likely to be indexed rather a generic myportfolio.com domain? I've seen mixed opinions where people seem to favor a WP domain for URL output where others say that it's a moot point, and that Google will not favor a WP domain over a dot com domain as long as your meta tags are updated and content is keyword optimized. I tend to disagree and believe a WP domain would more likely be indexed and output more URLs over an individual, laconic domain like myportfolio.com. Am I wrong?

• Scrolling Box2D DebugDraw

  - by onedayitwillmake

  I'm developing a game using Box2D (javascript implementation - Box2DWeb), and I would like to know how I can pan the debug draw. I know the usual answer is - don't use debug draw, it's just for debugging. I'm not, however not all my objects are on the same screen, and i'd like to see where they are in the physics representation. How can I pan the debug drawing? As you can see the debug draw stuff, is show on the top left, but it only shows a small part of the world. Here is an example of what I mean: http://onedayitwillmake.com/ChuClone/ The game is open source, If you'd like to poke through and note something that perhaps i'm doing something that is obviously wrong: https://github.com/onedayitwillmake/ChuClone Here's my hacky way that I'm using now to scroll the b2DebugDraw view, in which I added a property offsetX and offsetY into b2DebugDraw

• Algorithm to match items be value into sets base on total

  - by Ben

  Given n sets of items. Each item has a value. The items in a set have similar values but vary by a small amount. The goal is to create new sets containing three items selected from the original sets such that the total of the values is within a given range. Only one item a source set can be selected. For example: If we have the following starting sets: Set A - { 4.0, 3.8, 4.2 } Set B - { 7.0, 6.8, 7.2 } Set C - { 1.0, 0.9, 1.1 } Set D - { 6.5, 6.4, 6.6 } Set E - { 2.5, 2.4, 2.6 } Goal is to create sets containing three elements such that the total is between 11.9 and 12.1. For example { 3.8, 7.2, 1.0 } There can be unused elements. Can someone suggest an algorithm for this problem?

• How much server bandwidth does an average RTS game require per month?

  - by Nat Weiss

  My friend and I are going to write a multiplayer, multiplatform RTS game and are currently analyzing the costs of going with a client-server architecture. The game will have a small map with mostly characters, not buildings (think of DotA or League of Legends). The authoritative game logic will run on the server and message packet sizes will be highly optimized. We'd like to know approximately how much server bandwidth our proposed RTS game would use on a monthly basis, considering these theoretical constants: 100 concurrent users maximum 8 players maximum per game 10 ticks per second Bonus: If you can tell us approximately how much server RAM this kind of game would use that would also help a great deal. Thanks in advance.

• How do I become a programmer and not some guy that can type some C?

  - by Phoxxent

  From what I understand, programming has a lot more to it than learning syntax, that it involves an understanding of what happens under-the-hood and even more. Currently, I am just a guy that can pump out a few loops in Python or C and maybe make a small-scope Zork clone as the hight of skill. So, what can I do to become an actual programmer? How can I find out what I need to know and learn it? I know this has been vaguely asked before, but I kind of want an answer of how as opposed to the whats that I have seen. Would it be nice to know how real programmers define being a programmer? yes. Is that going to actually help me (or anyone else) learn what they need to learn? no. (well, maybe.)

• How to make Firefox windows style less space consuming?

  - by chocobai

  Firefox takes up so much space on small screens, so I'm searching for solutions that make firefox' interface less space consuming on ubuntu 12.04 with gnome3. Good examples are the chromium-style, but chromium is kind of slow in gnome3. Chromium does it, firefox on osx does it. Is this also possible on ubuntu via a custom modification or something? Here a screenshot of what I am thinking about: Firefox on OSX: https://wiki.mozilla.org/images/5/50/Firefox-4-Mockup-i06-%28OSX%29-%28TabsTop%29-%28Persona%29.png Thanks for your help.
