• APress Deal of the Day 9/Jan/2011 - Pro Silverlight 3 in VB

  - by TATWORTH

  Today's $10 deal from APress at http://www.apress.com/info/dailydeal is Pro Silverlight 3 in VB Silverlight is a lightweight browser plug-in that frees your code from the traditional confines of the browser. It's a rules-changing, groundbreaking technology that allows you to run rich client applications right inside the browser. Even more impressively, it's able to host true .NET applications in non-Microsoft browsers (like Firefox) and on non-Microsoft platforms (like Mac OS X). Silverlight is still new and evolving fast, and you need a reliable guidebook to make sense of it.

• How large of a swap partition is needed to hibernate?

  - by Closure Cowboy

  I've read this question, but it doesn't definitively answer my question. If I want my computer to be able to hibernate, do I need to have a swap partition as large as my RAM, or will Ubuntu wisely be able to hibernate if the swap partition can fit the currently-in-use RAM? I'm about to install Ubuntu on a computer with a lot of RAM, and a relatively small hard drive, so I don't want to use more hard drive space than necessary. I wanted to avoid giving my actual specifications to keep this question more general, though I'll give them if necessary.

• Hadopi : le code de ses logiciels sécuritaires sera totalement open-source, de quoi ouvrir la porte aux éditeurs

  Hadopi : le code de ses logiciels sécuritaires sera totalement open-source, de quoi ouvrir la porte aux éditeurs La Hadopi vient de donner sa première conférence de presse de 2011. Son secrétaire général, Eric Walter, y a fait une annonce importante à propos des "logiciels de sécurisation" que l'Etat demandera prochainement aux internautes d'installer sur leurs machines, professionnels comme particuliers. Ces programmes seront différentes pour les SI et les installations domestiques, et ce sont les utilisateurs qui en auront le contrôlé, via notamment trois "journalisations" (enregistrement de l'activité d'un ordinateur sur Internet) différentes : une absence (ne pas créer de journalisation), une en claire et un...

• Can not install Ubuntu 12.04 or 12.10 on Toshiba qosmio x870. Please help!

  - by Mighty

  I have a new Toshiba qosmio x870 and for the past one week I have been trying to install Ubuntu 12.04 from a USB and Live CD without success. I keep on getting this error: Boot failure: a proper digital signature was not found. One or more files on the selected boot device was rejected by the Secure Boot feature. I even tried installing Ubuntu with the Windows installer. After installation and I reboot the PC, first I see the error that points to: \ubuntu\winboot\wubildr.mbr Status: 0xc000007b Info: The OS couldn't be loaded because a required file is missing or contains errors. When I restart, that the previous error doesn't show up and I see both Windows 8 and Ubuntu (happy that I was successful) but when I click on Ubuntu, it flags an error. This is the first time I'm having a Secure Boot-capable PC. What will be the danger in disabling the secure boot? I'll be happy if I can get assistance from anyone.

• Acer Aspire microphone issue

  - by Dr_Bunsen

  I have got an Acer Aspire 7750G: More info It has been running Ubuntu since I bought the laptop (12.10 as of now), but a few updates ago, I lost my microphone. It doesn't recognise the internal mic or the mic jack (although alsa seems to recognise it). I have been looking around, and I fixed it, but this was only temporary, after a reboot my mic was gone again. I haven't been able to find the fix, so I wanted to know whatever you guys know what I have to do to fix this. Thanks in advance.

• Switching between Discrete and Integrated GPUs

  - by void-pointer

  Hello everyone, I develop CUDA applications on my Alienware M17x portable back-breaker, which has two discrete GTX 285M GPUs and one integrated GeForce 9400M GPU. I can currently switch between them using NVIDIA's software, but I would like the ability to do so within my applications for purposes of benchmarking and general convenience. Apparently this requires the "NDA version" of NVIDIA's Driver API, which I know not how to obtain. Would using this API be the only way to accomplish what I seek, and if so, how would I obtain it? A solution using Windows APIs would also be acceptable, though less preferable to one which would leverage a cross-platform API. I have created a similar thread concerning the matter on NVIDIA's forum, which is down at the time of this writing. Thanks for reading my question; it is much appreciated!

• What are the biggest barriers to walking the MOTU/developer path?

  - by maco

  For those who are not MOTU (people who maintain the Universe and Multiverse software repositories) and do not have plans of the "I will apply to MOTU by $date" variety: What keeps you and others like you from trying to become MOTU? What makes you think you couldn't become one? I'm referring to both social and technological barriers. EDIT: I'm only saying MOTU because it's a pretty generic group, but "why aren't you packaging / patching and intending to eventually try for upload rights?" is an even more general version.

• Designing a simple snake A.I

  - by DillPixel

  I've looked at some stuff online regarding this specific topic, and a lot of the info that I read involved graphs and path finding. I really don't want to get involved in something too complex & out of my level, and also I don't need my snake to be that intelligent (it will be a large board with the snake not growing in size on every munch). How could you structure a simpler AI for the snake that gets the job done relatively well? I would be able to get the snake to move towards the food item correctly, but my issue is that I'm not sure how to deal with the snake colliding with itself. Say the snake has a look ahead, and it finds that its tail is in the way, it could change direction, but what happens next? Any ideas on how to tackle this? Should the snake build an instruction set from every square, or should it think on the go?

• How do I change my PYTHONPATH to make 3,2 my default Python instead of 2.7.2?

  - by max

  I have python3.2 located in /usr/lib/python3.2. I am not sure if that means it's installed but I assume it is for now. Some facts about my system: $ which python /usr/local/bin/python When I type python in terminal I get the following $ python Python 2.7.2 (default, Dec 19 2011, 11:12:13) [GCC 4.4.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. Then to find the path I do >>> sys.info >>> sys.path ['', '/usr/local/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg', '/usr/local/lib/python2.7/site-packages/pip-1.0.2-py2.7.egg', '/usr/local/lib/python2.7/site-packages/PIL-1.1.7-py2.7-linux-x86_64.egg', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages'] So knowing all of this, how do I change my default system python from 2.7.2 to 3.2?

• Part-time work as a beginner programmer [on hold]

  - by Valentas

  I wrote to one company near my university (starting in September) and they responded that they will probably hire me from the work I have already done (some projects and Euler problems solving). It's for 15 hours/week or so in order to not fall behind uni work. They require Python, SQL, XML and a good idea about how the Web works. The job role involves acquiring data from the Web and supplying it as search results for flight seekers (people). I am eager to learn but still, what can I do to become prepared for this? I ask because I tend to gravitate from one technology to the other, trying out things but never mastering it properly. What Web technologies are involved in such a job role? I have two months and want to learn as much as possible because there is much info but I have no idea where to start.

• Some help understanding and modifying a 2D shader

  - by electroflame

  I have a similar question as the one posed here, except that I don't wish to use a 1D Color Palette. I simply wish to have it display 1 color of my choosing (red, for example). I plan to use this as a "shield" effect for a 2D ship. I also wish to understand how it works a little bit better, as I'll be the first to admit that shaders in general are not my strongest suit. I'm not asking for an overview of HLSL (as that is too broad of a subject), just an explanation of how this shader works, and the best way to implement it in a 2D game. Code examples would be ideal (even if they are theoretical) but if the answer is explained well enough, I might be able to manage with plain old text. This is also in XNA 4.0. Thanks in advance.

• Red Gate join the SSIS custom component club

  I recently noticed that Red Gate have launched themselves into the SSIS component market by releasing a new Data Cleanser component, albeit in beta for now. It seems to be quite a simple component, bringing together several features that you can find elsewhere, but with a suitable level  polish that you’d expect from them. String operations include find and replace with regular expressions, case formatting and trim, all of which are available today in one form or another, but will the RedGate factor appeal to people? Benefits include ease of use, all operations in one place, versus installing a custom component which many organisations do not like. I’m also interested to see where they take this and SSIS products in general, as it almost seems too simple for RedGate, a company I normally associate with more advanced problem solving. Perhaps they are just dipping a toe in the water with a simple component for now?

• 301 re-direct all external links to new domain

  - by Dean Legg

  I have changed the main domain to a sub-domain & would like to re-direct all external links to the new sub domain. Have read a few articles but having no luck editing the .htaccess as it might be interfering with all the rules in there. Old: www.example.co.uk New: https://secure.example.co.uk The current rules are quite handy because it seems to have sorted out the structure for all internal links. It has even updated the file path for images (or this could just be wordpress as the url was updated under general settings). This is the current .htaccess <files wp-config.php> order allow,deny deny from all </files> # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress

• error: you need to load kernel first

  - by Angelos318

  I made a clean install on my Sony Vaio laptop, of Ubuntu 11.10 and when the installation was ready, it prompted to remove the usb I was installing the distro from, and press enter to reboot. After this reboot the first thing I got was the following error: error: couldn't read file error: you need to load the kernel first Press any key to continue.. After that it throws me back to the Grub select screen: Ubuntu, with linux 3.0.0-14-generic-pae recovery mode previous linux versions (none since I made a clean install) memory test If i choose the first option it shows only a black screen and never loads anything. If i reboot the same thing happens. Could I repair this using boot-repair? Is there any other way? Note: I know nothing about linux code so i am a total noob on this one Update: boot-repair did not help Grub.cfg here: http://pastebin.com/GKLuDuhM Boot Info Script: http://pastebin.com/indARkKJ

• Number Game Algorithm

  - by 7Aces

  Problem Link - http://www.iarcs.org.in/inoi/2011/zco2011/zco2011-1b.php The task is to find the maximum score you can get in the game. Such problems, based on games, where you have to simulate, predict the result, or obtain the maximum possible score always seem to puzzle me. I can do it with recursion by considering two cases - first number picked or last number picked, each of which again branches into two states similarly, and so on... which finally can yield the max possible result. But it's a very time-inefficient approach, since time increases exponentially, due to the large test cases. What is the most pragmatic approach to the problem, and to such problems in general?

• Who owns the code, who owns the algorithm, who owns the idea?

  - by Vorac

  This question got me thinking what products of the programming effort belong to the employer, and what don't. The two extremes are (0) the code - it apparently belongs to the employer and (1) the learned personal and technical skills. But what is in between? Who owns the pseudocode/algorithm? Who owns the general idea of the algorithm? Who owns the know-how that such an algorithm may serve some useful purpose (e.g. on this site questions are values, as well as answers)? Also: Who owns an idea on the web?

• How to document and teach others "optimized beyond recognition" computationally intensive code?

  - by rwong

  Occasionally there is the 1% of code that is computationally intensive enough that needs the heaviest kind of low-level optimization. Examples are video processing, image processing, and all kinds of signal processing, in general. The goals are to document, and to teach the optimization techniques, so that the code does not become unmaintainable and prone to removal by newer developers. (*) (*) Notwithstanding the possibility that the particular optimization is completely useless in some unforeseeable future CPUs, such that the code will be deleted anyway. Considering that software offerings (commercial or open-source) retain their competitive advantage by having the fastest code and making use of the newest CPU architecture, software writers often need to tweak their code to make it run faster while getting the same output for a certain task, whlist tolerating a small amount of rounding errors. Typically, a software writer can keep many versions of a function as a documentation of each optimization / algorithm rewrite that takes place. How does one make these versions available for others to study their optimization techniques?

• Why Java as a First Language?

  - by dsimcha

  Why is Java so popular as a first language to teach beginners? To me it seems like a terrible choice: It's statically typed. Static typing isn't useful unless you care a lot about either performance or scaling to large projects. It requires tons of boilerplate to get the simplest code up and running. Try explaining "Hello, world" to someone who's never programmed before. It only handles the middle levels of abstraction well and is single-paradigm, thus leaving out a lot of important concepts. You can't program at a very low level (pointers, manual memory management) or a very high level, (metaprogramming, macros) in it. In general, Java's biggest strength (i.e. the reason people use it despite the shortcomings of the language per se) is its libraries and tool support, which is probably the least important attribute for a beginner language. In fact, while useful in the real world these may negatives from a pedagogical perspective as they can discourage learning to write code from scratch.

• Battery Power when running Ubuntu 14.04 LTS in dual boot

  - by Amro A.

  This is only a general question in order for me to get a better idea of my dual boot (windows 8 & Ubuntu) systems. I noticed that every time I run Ubuntu (which is becoming more often) the battery power gets consumed really fast. I am not performing any special tasks at the moment, just getting to know the system, for example, sound settings, watching videos, surfing the net and so on. When I do the same thing in Windows 8 the battery lives a considerable amount of time longer. Is this something to do with Ubuntu or is it because of the dual boot that I have going on? In other words, if I start running Ubuntu all by itself on my laptop, will it be more power consuming than Windows 8?

• html5 based advertisement guidelines

  - by picus

  I want to experiment with the idea of an html based ad that utilizes my company's search API, is anyone here aware of any rules or documentation (general or per network) that explains the guidelines for creating such ads - ie markup, delivery etc - note this is not a question on how to use my company's api, I already know how to do that. For example, I would like to access the api with jsonp, probably via jquery? Can this be done? Would I host the ad and have loaded via an iframe? I just don't know these things. It is all so new to me... I... I'm scared. Actually, I'm not. However, I would like to know. Thanks in advance.

  Next Thursday there’s a bada developer day in Amsterdam, co-sponsored by Vodafone, at which I’ll speak. Entrance is free, although registration is required so that the organisers know how many people will be coming.I’m intererested in bada on general principles; it’s going to be a major new smartphone platform, and I’d like to know what it can and cannot do. Besides I’m curious about the Samsung WebKit that runs on it. I briefly guerilla-tested it in Barcelona, but would like to have a more formal...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?
