• Video Training Courses for Linux/Ubuntu?

  - by Anil

  I'm a software developer with more than 15 years of experience on Windows platform, focused on C#/.NET/SQL Server stack. Recently I decided to explore Linux and learn a new development technology stack which is completely unrelated to Microsoft. After a bit of (re)search/reading I picked Ubuntu as my starting point. As I'm really a Pluralsight addict, preferring video courses as a starting point for learning new stuff, I wanted to ask if there are any decent video courses for Linux generally or Ubuntu focused ones? Basically I'm searching for general explanation of OS structure, a bit of system administration, and maybe some considerations for development on Linux system.

• SharePoint Content Database Sizing

  - by Sahil Malik

  SharePoint, WCF and Azure Trainings: more information SharePoint stores majority of its content in SQL Server databases. Many of these databases are concerned with the overall configuration of the system, or managed services support. However, a majority of these databases are those that accept uploaded content, or collaborative content. These databases need to be sized with various factors in mind, such as, Ability to backup/restore the content quickly, thereby allowing for quicker SLAs and isolation in event of database failure. SharePoint as a system avoids SQL transactions in many instances. It does so to avoid locks, but does so at the cost of resultant orphan data or possible data corruption. Larger databases are known to have more orphan items than smaller ones. Also smaller databases keep the problems isolated. As a result, it is very important for any project to estimate content database base sizing estimation. This is especially important in collaborative document centric projects. Not doing this upfront planning can Read full article ....

• Performance cost of running Ubuntu from external hard drive

  - by dandan78

  A friend just complained to me about Ubuntu being slow. Although I've noticed a certain lack of snappiness with Linux vs Windows in the past, I really can't say I've had much to grumble about with the recent distributions of Ubuntu. That said, his objections seem much worse than the ones I used to have and I know that his current setup is significantly more powerful than my laptop. And then it turned out he is running Ubuntu off an external HDD hooked up via USB2.0. The HD enclosure is USB3.0 but apparently he can't manage to get it to boot on USB3.0 so he switched to one of the USB2.0 ports or whatever and that works, albeit not very well. Now I would expect USB to add some overhead to communication between the computer and the HDD; SATA is after all designed to get the maximum out of a hard drive, whereas USB is, well, universal. What are your expreriences with booting off external HDDs? Edit: Does anybody know just how much of a slowdown can be expected?

• Wordpress html email plugin that doesn't merge with your users?

  - by christian

  I just launched a wordpress site as a redesign of my strictly html site and added my blogger blog to Wordpress to keep it all in one place. I am trying to send an html email from my Wordpress site to all of my blogger subscribers encouraging them to subscribe to my new blog and join my newly created membership program, but every html email plugin (that I have found) imports your your users with you Wordpress users before you can send them an email. Is there a plugin that allows me to send an html email to a list of email address without adding them as users? otherwise I will have to go through and delete all of my users (after importing the list and sending the email) and try to pick out my legitimate users who have already signed up all the while watching for new ones to make sure I don't delete them.

• Asset displays in the UI

  - by Owen Allen

  I've seen a little bit of confusion about how the UI displays assets and asset information, so I thought I'd explain how information and actions are displayed.  In Ops Center, operating systems, servers, zones, Oracle VM Servers, and anything else that you can manage are called assets. When you discover them, Ops Center puts together a model in the navigation pane that shows the relationships between the assets. For example: This tree shows three servers, and the Operating Systems on each one. If one of the operating systems was a global zone, we'd see the non-global zones beneath the global zone as well. However, when you select an asset, the info in the center pane and the actions in the actions pane are the ones that apply to that specific asset, and not to its related assets. If you select a server, for example, you'll see service request info and have the option to provision a new OS. If you select an existing OS, you'll see file system information and have the option to update the OS. Actions that apply directly to the hardware aren't visible from the OS view, and vice versa.

• Weekly technology meeting?

  - by Mag20

  I am thinking of introducing weekly technology meeting where programmers working on the same project can discuss things like: current status of the project on technical side technology backlog. Things that we may have skipped because of deadlines but now coming back to bite us. technology constraints that are limiting developers from being productive new and emerging technologies that may apply to the project Basically looking at the project from programmer's perspective, not the business side. - What would be some good guidelines for a meeting like this? How long should the meeting last? Is weekly too often? Should we time-limit each topic? What kinda of topics are good for a meeting like this and which ones are bad? Is 10 people too many? ...

• Recommend good shared hosting [closed]

  - by Django Reinhardt

  It seems that everyone has something bad to say about the "big" shared hosting sites like 1and1, HostGator, GoDaddy, etc. but what are the ones you've had GOOD experiences with? I'm going to focus this question on LAMP stacks, given that they're the most popular option for shared hosting, but if you have an especially good experience with a different stack. Good shared hosting should be: Competitively priced - But not at the expense of... Fully featured - Email, PHP, MySQL, but what else? Highly customizable - Do you have access to advanced features like being able to deliver static content? Up to date - Do they run PHP4 as standard, or do they run the latest version? Customer service - When you have a problem are they rude and unhelpful? Do they take ages to reply? So how about it? Who have YOU have a good experience with?

• DNS MX and NS entries

  - by unkown

  I was wondering about my domain and if next is afordable. First of all this is my "architecture": Domain registration at GoDaddy.com Hosting at Dreamhost mail at google apps Until now I setted up the google apps MX entries in my domain through the GoDaddy manager, but now what I want is to set up the hosting I have hired from Dreamhost. I understand that all I have to do is to setup next Dreamhost NS entries into the GoDaddy domain manager: NS1.Dreamhost.COM. 66.33.206.206 NS2.Dreamhost.COM. 208.96.10.221 NS3.Dreamhost.COM. 66.33.216.216 My question is, will my mail keep working right as soon as the MX entries I already setup into the GoDaddy are the Google Apps ones?

• install Cirrus Logic cs46xx (audio card) drivers

  - by Aikanáro

  I have two sounds cards, one is the on-board (it's VIA) the other is Cirrus Logic cs46xx. This is what lspci shows me: 04:04.0 Multimedia audio controller: Cirrus Logic CS 4614/22/24/30 [CrystalClear SoundFusion Audio Accelerator] (rev 01) It only show the cirrus logic, cause I disable the VIA card through BIOS. This page: http://es.driverscollection.com/?file_id=13152 gives me instructions to install it, but I can follow them because the folders indicates in the page do not matches with the ones that I see in my system. The alsa page: http://alsa-project.org/main/index.php/Matrix:Module-cs46xx, also give me instructions, but I don't understand it. For example, they say: type in a terminal: ./configure but don't say in what directory. I think that isn't instructions for begginers... Right now I can't heard anything. I decide to disable the VIA audio card, cause I've read they don't get along with linux, although i use the integrate VIA video card. I have ubuntu 11.10

• Should I update blog posts or rewrite them as technology (and me) changes?

  - by Rachel

  I started a programming blog earlier this year, and since I started it some things have changed. Some changes are due to technology changing, some changes are due to my code libraries improving, and some (ok, probably most) are due to me changing as I learn more. I want to go back and completely re-write certain blog posts. Is it better to rewrite posts to remove old information and update them with new stuff, or to create entirely new posts and possibly take down old ones? I'm not talking about small changes to the code, or an extra few sentences, but complete rewrites with new code, new information, etc. Some things to consider are comments on the post, subscribers who receive updates when new posts are created, and user bookmarks.

• Strategies to Defeat Memory Editors for Cheating - Desktop Games

  - by ashes999

  I'm assuming we're talking about desktop games -- something the player downloads and runs on their local computer. Many are the memory editors that allow you to detect and freeze values, like your player's health. How do you prevent cheating via memory-modifiation? What strategies are effective to combat this kind of cheating? For reference, I know that players can: - Search for something by value or range - Search for something that changed value - Set memory values - Freeze memory values I'm looking for some good ones. Two I use that are mediocre are: Displaying values as a percentage instead of the number (eg. 46/50 = 92% health) A low-level class that holds values in an array and moves them with each change. (For example, instead of an int, I have a class that's an array of ints, and whenever the value changes, I use a different, randomly-chosen array item to hold the value)

• Creating natural environments that can run on lower end computers in Unity3D/C#

  - by Timothy Williams

  So, I'm starting work on a project soon that will require me to create realistic environments that can preferably run on PC's besides high quality ones. The goal is to get as real an environment as possible while still being easy(ish) to run. The only problem is I've NEVER done anything with 3D environments, making trees sway, grass move, lighting, etc. Can anyone give me any help? Perhaps describe how it's done? Link me to articles? I'm just looking to be pointed in the right direction, not for you to write the code for me. Any help at all would be greatly appreciated, I'm using Unity3D and C# as my language. Thanks, Tim.

• Your experience with haxe and other languages that compile to PHP?

  - by Kim

  I would like to hear oppinions from people who have used a language that compiles to php. One such language I know is Haxe. Other ones I've read about are Kira and Pharen. How well do these languages integrate with PHP? Is it relatively easy to write a plugin for a PHP CMS in them? How mature are their implementations and tools? Would you recommend them to someone who has to use a php cms but hates php?

• What package do I need to build a Qt 5 & CMake application?

  - by Kevin Reid

  I'm trying to build sdrangelove, which wants Qt 5 and uses CMake for its build system, on Ubuntu 13.10. What package do I need to install to give it the file it's asking for here? There are a lot of *qt5* packages, and I've tried installing the promising looking ones to no effect. All the discussions I've found either have things working fine or are talking about writing CMake build rules rather than executing them. I don't have a lot of experience with the organization of Debian/Ubuntu packaging. CMake Error at CMakeLists.txt:14 (find_package): By not providing "FindQt5Core.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "Qt5Core", but CMake did not find one. Could not find a package configuration file provided by "Qt5Core" (requested version 5.0) with any of the following names: Qt5CoreConfig.cmake qt5core-config.cmake Add the installation prefix of "Qt5Core" to CMAKE_PREFIX_PATH or set "Qt5Core_DIR" to a directory containing one of the above files. If "Qt5Core" provides a separate development package or SDK, be sure it has been installed.

• what is the simplest 3d software for unity?

  - by kdavis8

  Ive heard a lot about Daz studio, Poser, Maya, K-3d, Anim8or, Blender, and all the rest. My question is which one is the best choice in terms of simplicity and quality. price is not an issue really. I'm programming games in java for android mobile devices at the moment but i will eventually move onto larger platforms. I would like to utilize unity3d for the game programming itself and utilize a 3d modeling software just to create the game objects. I just need to know the best one to get started with from scratch or should i use a combination of multiple ones? Any insight for this would be great, thanks!

• Google Site Search -- How to use as API?

  - by John Isaacks

  I am trying to get an API that I can use to do searches on my own site. Google has something called site search and something called custom search. What is the difference? I make a new site search, then it is listed on a page with "custom search" in the heading. This is really confusing. I just want an API that I can use to search my site. I would prefer json to xml as the results. And if this service is offered by someone other than Google, that is fine too. The ones that I create at Google want me to embed a premade search box into my site. I do not want that, I want an API that I can call from PHP or JS. How can I get this?

• How can I remove gradients from Elementary theme?

  - by John

  I really don't like the gradients in the Elementary theme and I was wondering if there is a way to remove them from applications like Nautilus-Elementary, Postler, Dexter, etc. I've tried commenting out the Apps/[Application].rc in /usr/share/themes/elementary/gtk-2.0/gtkrc but it doesn't work. It still leaves the gradients in their place. I'm a big fan of the other controls in the theme: the scroll bar, the way it borders gedit and the buttons, and I'd like to keep these features, but I don't like the way it styles its windows. EDIT: The gradients I'm talking about are the ones at the top of the window. Some examples: Nautilus-Elementary: Postler: Rhythmbbox: Transmission: I'd like to create a sort of matte look, similar to this, which was done using Orta: Nautilus-Elementary: Postler: Rhythmbox: Transmission: I'd like a flat color, preferably without the line separating the top part of the application with the bottom.

• Working on someone else's code

  - by Xavi Valero

  I have hardly a year's experience in coding. After I started working, most of the time I would be working on someone else's code, either adding new features over the existing ones or modifying the existing features. The guy who has written the actual code doesn't work in my company any more. I am having a hard time understanding his code and doing my tasks. Whenever I tried modifying the code, I have in some way messed with the working features. What all should I keep in mind, while working over someone else's code?

• Burning Snow Leopard DMG on Ubuntu

  So I have a SL Copy of Mac OS X Snow Leopard.DMG and I am running Ubuntu 12.0.4. I tried burn the DMG to a DVD using CD/DVD Creator however when I try, it comes up with a message saying 'The size of the file is over 2 GiB. Files larger than 2 GiB are not supported by the ISO9660 standard in its first and second versions (the most widespread ones). It is recommended to use the third version of the ISO9660 standard, which is supported by most operating systems, including Linux and all versions of Windows™. However, Mac OS X cannot read images created with version 3 of the ISO9660 standard.' How do I bypass this so my DVD is bootable on my iMac. By the way, I'm running Ubuntu on the iMac and it is my only partition. No other OS Installed

• Topics for development team cross training sessions

  - by BBlake

  Our team of developers are going to start holding monthly meetings for the purposes of cross training and knowledge improvement. We're looking for ideas for topics to discuss. We've already made a list of some obvious ones, such as discussions/training on specific applications, proper usage of TFS for source control, bug tracking and code reviews, coding standards, and corporate architecture. The problem we're having is that we are a cross-platform development team so we don't want to look at topics that only apply to certain members of the team (Sql, .NET, reporting, third party apps, etc). We'll use sub-team meetings for those. So what other topics that would apply across a broad development team would be good for these training sessions?

• Should I block bots from my site and why?

  - by Frank E

  My logs are full of bot visitors, often from Eastern Europe and China. The bots are identified as Ahrefs, Seznam, LSSRocketCrawler, Yandex, Sogou and so on. Should I block these bots from my site and why? Which ones have a legitimate purpose in increasing traffic to my site? Many of them are SEO. I have to say I see less traffic if anything since the bots have arrived in large numbers. It would not be too hard to block these since they all admit in their User Agent that they are bots.
