• Learning to be a good developer: what parts can you skip over?

  - by Andrew M

  I have set myself the goal of becoming a decent developer by this time next year. By this I mean full experience of the development 'lifecycle,' a few good apps/sites/webapps under my belt, and most importantly being able to work at a steady pace without getting sidelined for hours by some should-know-this-already technique. I'm not starting from scratch. I've written a lot of html/css, SQL, javascript, python and VB.net, and studied other languages like C and Java. I know about things like OOP, design patterns, TDD, complexity, computational linguistics, pointers/references, functional programming, and other academic/theoretical matters. It's just I can't say I've really done these things yet. So I want to get up to speed, and I want to know what things I can leave till a later date. For instance, studying algorithms and the maths behind them is interesting and all, but so far I've hardly needed to write anything but the most basic nested loops. Investigating Assembly to have a clearer picture of low-level operations would be cool... but I imagine rarely infringes on daily work. On the other hand, looking at a functional programming language might help me write programs that are more comprehensible and less prone to hidden failures (at the moment I'm finding the biggest difficulty is when the complexity of the app exceeds my capacity to understand it - for instance passing data around was fine... until I had to start doing it with AJAX, which was a painful step up). I could spend time working through case studies of design patterns, but I'm not sure how many of them get used in 'real life.' I'm a programmer with basic abilities - what skills should I focus on developing? (also my Unix skills are very weak, and also knowledge of Windows configuration... not sure how much time I should spend on that)

• RUEI 12.1.0.3.0 dependency requirement for php-soap-5.1.6

  - by sthieme

  Dear Readers,please be aware of the new php-soap-5.1.6 dependency in RUEI 12.1.0.3.For a swift upgrade to RUEI 12.1.0.3 you should be aware of this pre-requisite as it can be a time-eater to obtain individual rpm-packages inside of a datacenter for an old OS revision once you have started the upgrade process. You may use the following procedure to retrieve the required package via http://public-yum.oracle.com:Customers will have to check the /etc/issue, /etc/issue.net (or /etc/redhat-release for RHEL based OS) for their current release in order to obtain the fitting package version.Customers of OEL can download the packages from our public-yum.oracle.com Server: http://public-yum.oracle.com/repo/,  e.g. http://public-yum.oracle.com/repo/OracleLinux/OL5/8/base/x86_64/php-soap-5.1.6-32.el5.x86_64.rpmEarlier releases (up to 5.5) are located under the EnterpriseLinux instead of OracleLinux path, e.g.http://public-yum.oracle.com/repo/EnterpriseLinux/EL5/5/base/x86_64/php-soap-5.1.6-27.el5.x86_64.rpmNote: you will have to obtain the relevant RedHat rpm-packages via the login protected RHN URLs. Oracle can only provide support for Oracle Enterprise Linux and RHEL packages are not available publicly via rpm-seek.com to my knowledge. Kind regards,Stefan

• Taking our Friendships to the next level.

  - by RedAndTheCommunity

  Red Gate have been running the Friends of Red Gate program for years now, and over that time we've built some great relationships with some truly awesome members of the SQL and .NET communities. When I took over the running of the program from Annabel in 2011, I was overwhelmed by the enthusiasm and commitment of our Friends. There were just so many of them, however, that it was hard to make the most of the relationships we had with people, and I wanted to fix that. I decided to survey all our Friends, to find out what they wanted to get out of, and put into, being in the Friends of Red Gate (FoRG) program. From the results of that survey, I identified 30 FoRGs that were really willing and able to go that step further to help Red Gate improve their tools, improve their relationship with the community, and improve the Friends of Red Gate program. Those 30 Friends of Red Gate have been awarded 'FoRG+' status. That means they'll: Have a closer relationship with the product teams, by getting involved in projects Have even more access to the inside track about the tools they're interested in Get the opportunity to come visit us at the Red Gate office and really influence the development of the tools. Plus more, depending on how the individual FoRG+ wants to work with us. This doesn't mean I've forgotten our other Friends; I'm working on ways to improve their experience of the Friends of Red Gate program. I'll write about them in another post. If you're an existing Friend of Red Gate, and you're interested in finding out how to get involved in the FoRG+ program, then I'd love to chat to you. For anyone that's interested in joining the Friend of Red Gate program, take a look at the web page dedicated to the program, and get in touch at [email protected] to be put on the waiting list for our 2013 program.

• Which shopping cart / ecommerce platform to choose?

  - by fabien7474

  I need to build an ecommerce website within a tight budget and schedule. Of course, I have never done that before, so I have googled out what my solutions are and I have concluded that the following were not valid candidates anymore : Magento : Steep learning curve osCommerce : old, bad design, buggy and not user-friendly Zencart, CRE Loaded, CubeCart : based on osCommerce Virtuemart, uberCart, eCart : based on CMS (Joomal, Drupal, WordPress) that is not necessary for my use-case So I finally narrowed down my choices to these solutions : PrestaShop : easy-to-use, great templating engine (smarty) but many modules are not free buy yet indispensable OpenCart : security issues and not a great support from the main developer. See here and here. So, as you can see, I am a little bit confused and if you can help me choosing an easy-to-use, lightweight and cheap (not-necessarily free) ecommerce solution, I would really appreciate. By the way, I am a Java/Grails programmer but I am also familiar with PHP and .NET. (not with Python or Ruby/Rails) EDIT: It seems that this question is more appropriate for the Webmaster StackExchange site. So please move this question to where it belongs (I cannot do that) instead of downvoting it. BTW, I have found out a question quite similar on SO (http://stackoverflow.com/questions/3315638/php-ecommerce-system-which-one-is-easiest-to-modify) which is quite popular.

• How do I properly use String literals for loading content?

  - by Dave Voyles

  I've been using verbatim string literals for some time now, and never quite thought about using a regular string literal until I started to come across them in Microsoft provided XNA samples. With that said, I'm trying to implement a new AudioManager class from the Net Rumble sample. I have two (2) issues here: Question 1: In my code for my GameplayScreen screen I have a folder location written as the following, and it works fine: menuButton = content.Load<SoundEffect>(@"sfx/menuButton"); menuClose = content.Load<SoundEffect>(@"sfx/menuClose"); If you notice, you'll see that I'm using a verbatim string, with a forward slash "/". In the AudioManager class, they use a regular string literal, but with two backslashes "\". I understand that one is used as an escape, but why are they BACK instead of FORWARD? (See below) soundList[soundName] = game.Content.Load<SoundEffect>("audio\\wav\\"+ soundName); Question 2: I seem to be doing everything correctly in my AudioManager class, but I'm not sure of what this line means: audioFileList = audioFolder.GetFiles("*.xnb"); I suppose that the *xnb means look for everything BUT files that end in *xnb? I can't figure out what I'm doing wrong with my file locations, as the sound effects are not playing. My code is not much different from what I've linked to above. private AudioManager(Game game, DirectoryInfo audioDirectory) : base(game) { try { audioFolder = audioDirectory; audioFileList = audioFolder.GetFiles("*.mp3"); soundList = new Dictionary<string, SoundEffect>(); for (int i = 0; i < audioFileList.Length; i++) { string soundName = Path.GetFileNameWithoutExtension(audioFileList[i].Name); soundList[soundName] = game.Content.Load<SoundEffect>(@"sfx\" + soundName); soundList[soundName].Name = soundName; } // Plays this track while the GameplayScreen is active soundtrack = game.Content.Load<Song>("boomer"); } catch (NoAudioHardwareException) { // silently fall back to silence } }

• Learn to Take a Punch, Learn to Counter, Keep Moving Forward

  - by D'Arcy Lussier

  Originally posted on: http://geekswithblogs.net/dlussier/archive/2013/10/28/154483.aspxDuring a boxing workout a few months ago our trainer had us do something called “breadbaskets”. That’s where you hold your arms up and a partner punches you in your midsection – your breadbasket. I put my arms up, and braced for impact. The trainer came over, saw I was a bit nervous, and coached me through. I can see the fear in your eyes. Don’t be afraid to take the punch. Tighten your core, breathe through the hit. Don’t panic. Over the summer we’d do counter drills as well. This is where a partner throws a punch, you defend but also throw one back – a counter punch. You never just sit back and take a beating, you deflect the blow and come back with one more powerful. These lessons on fighting can apply to all aspects of our lives and any attempts at success that we have. I saw this image recently and agree with it 100%: Success is never a straight forward line. It’s messy, its wrought with failures, its learning over time and applying those life lessons. It’s learning how to take punches and lose your fear, its seeing a punch coming and countering it, but most of all its not giving up and continually moving forward. We do stairs at boxing, which is running up and down three flights of stairs. I’m not anywhere near incredible shape and after doing multiple stairs in a single workout you can feel gassed, tired, even discouraged after hitting the second floor and seeing everyone else running by you. I read a quote from Martin Luther King Jr. that I cling to throughout my day: You want to be successful? Take the punches, but learn how to take them. Counter them. and no matter what, always move forward.

• So, whats the best book on C#?

  - by mbcrump

  I see this question several times a day from newbie’s to professionals. I have listed the best C# books that I have read so far.   ECMA-334 C# Language Specification. – FREE book. This is probably the best place to start. Read it backwards and forwards and you can even request a hard copy. Absolute Beginners Guide to C Sharp 2nd Edition – Used this early on and found it very useful even if its game programming. C-Sharp 2.0 - The Complete Reference, 2nd Edition (McGraw-Hill, 2006) – One of the most useful books that is always with me. It contains short example code and is very well written. Dot Net Zero - Charles Petzold  - FREE book and you should definately give it a read. C Sharp in Depth by Jon Skeet -  Probably one of the most in depth books on C Sharp and definitely not for beginners. Jon Skeet knows C# like no other. I would consider this book the Bible of C#. If you understand 50% of this book, you have a good understanding of the language.  CLR via C Sharp 3rd Edition – I just started reading this book and it is another book thats not for beginners. If you really want to understand the CLR then give this book a try. Well, thats it. I hope you enjoy the books as I have spent a lot of time researching different C# books.

• Can't reinstall VLC

  - by David matthews

  I use VLC a lot. And when 2.0 came out Ubuntu did not update to that version, the REPO had the older version even months later, So I added the daily repo: http://ppa.launchpad.net/videolan/stable-daily/ubuntu and that worked for a while, after a few months later I received a 'Distribution upgrade' and when I installed it, it removed VLC. when I tried to re-install it gave me a bunch of unmet dependency's, so I disabled the source, ran apt-get update, and tried to install the older VLC, that did not work either. I eventually found a web page, and it helped me get it working, and I was also able to get the 'Stable Daily' working too But last night, I got another 'distro upgrade' and it uninstalled VLC again. when I try to reinstall from daily I get: The following packages have unmet dependencies: vlc : Depends: fonts-freefont-ttf but it is not installable Depends: vlc-nox (= 2.0.3+git20121005+r392-0~r42~precise1) but it is not going to be installed Depends: libvlccore5 (>= 2.0.0) but it is not going to be installed Recommends: vlc-plugin-notify (= 2.0.3+git20121005+r392-0~r42~precise1) but it is not going to be installed Recommends: vlc-plugin-pulse (= 2.0.3+git20121005+r392-0~r42~precise1) but it is not going to be installed E: Unable to correct problems, you have held broken packages. and from the default source: vlc : Depends: vlc-nox (= 2.0.3-0ubuntu0.12.04.1) but it is not going to be installed Depends: libvlccore5 (>= 2.0.0) but it is not going to be installed Recommends: vlc-plugin-notify (= 2.0.3-0ubuntu0.12.04.1) but it is not going to be installed vlc-plugin-pulse : Depends: vlc-nox (= 2.0.3-0ubuntu0.12.04.1) but it is not going to be installed Depends: libvlccore5 (>= 2.0.0) but it is not going to be installed E: Unable to correct problems, you have held broken packages.

  - by Ken Lovely, MCSE, MCDBA, MCTS

  Are you ready to connect with the local tech community for a good cause? GiveCamp needs your support. For one weekend in June, we’ll take on the technology wish lists of 20 non-profit organizations, and we’re looking for about 100 volunteers, both technical and non-technical, to help us do it. A typical GiveCamp draws 75 to 100 volunteers. Individuals can work with their colleagues in company teams, or they can opt to be matched with fellow volunteers who have complementary skill sets. Everyone is welcome to head home for the evenings – but there are always the diehards who work from Friday kickoff straight through Sunday afternoon. Food and drinks, especially of the caffeinated variety, are provided, along with game systems for breaks. Technical volunteers We're looking for graphic or UX designers, developers with .NET/Java/LAMP/Open Source/CMS experience, project managers, system/network administrators, DBAs, and non-profit technical consultants and web strategists. Non-technical volunteers Beyond the technology, there are many other aspects that make GiveCamp a success.

• Reflector Pro has now been released!

  - by CliveT

  After moving into the .NET division in May , and having a great time working on Reflector, I'm pleased to say that the results of that work are now available. Reflector Pro has now been released! The old Reflector as you know and love it is still available free of charge, and as part of this project we've fixed a number of bugs in the de-compilation that have been around for a long time. The Pro version comes as an add-in for Visual Studio - this offers dynamic de-compilation and generation of pdb files which allow you to step into the de-compiled code. Alex has some good pictures of this functionality on his beta post from around a month ago. Thanks to the other guys who've worked on this for taking me along for the ride - Alex, Andrew, Bart and Jason. Stephen did some great usability work, Chris Alford did some great technical authoring and Laila handled the launch publicity. Like all projects, there's always more I'd like to have done, but what we have looks like a pretty powerful addition to the developer's set of tools to me. Please try it and give us feedback on the forum.

• Alt-Tab looses focus and have to hit Alt-Grave Accent to get focus

  - by John Hamill

  Alt-Tab looses focus and have to hit Alt-Grave Accent to get focus I have ubuntu 12.4 with Unity window manager. I have a gvim window and a firefox window open. I hit Alt-Tab to switch between the two. Sometimes the gvim window doesn't have focus and I have to hit Alt-GraveAccent (Alt-`) to get the gvim window to have focus (ie: have the cursor a solid white square instead of a outline of a square) I do this to move between firefox where I highlight some text and do a copy, then Alt-Tab to gvim and do a paste. Sometimes the focus isn't in gvim and the paste doesn't work. I then have to do an Alt-graveAccent to get the focus into gvim or click the gvim window. These extra steps slow my process down and it makes it difficult to get into a smooth rythum. I saw this: ALT+TAB loses focus Maybe the Alt-GraveAccent may help someone. It's a unity bug: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1035628 Your best bet is to wait until an update comes through fixing it.

• How To Change Window Transparency in Windows 7 with a Hotkey

  - by YatriTrivedi

  Linux has a lot of eye-candy because of Compiz, my favorite of which is the window opacity plugin. Using a short AutoHotKey script, you can add that same functionality to Windows 7. I used this AHK script as a basis for changing opacity. It uses a single hotkey to change the active window’s transparency by 25% each time until it resets to 0. I wanted functionality similar to Compiz, so I modified the script to use the mouse wheel and shortened the increments to get more variety. Just hold down the Windows key and scroll down to see through the window. This decreases opacity and makes windows more transparent.

• Is comparing an OO compiler to a SQL compiler/optimizer valid?

  - by Brad

  I'm now doing a lot of SQL development at my new job where as before I was doing Object Oriented desktop app stuff. I keep running across very large scripts (thousands of lines) and wanting to refactor in some way. I am seeing that SQL is a different sort of beast and it's probably fine to have these big scripts for the most part but while explaining this to me people are also insisting that the whole idea of refactoring is bad. That stuff like the .NET compiler are actually burdened by refactored code and that a big wall of code is more efficient and better design than code designed for reuse, readability and scalability. The other argument is that OO compilers are almost dangerously inefficient and don't have efficient memory management or runs too many CPU instructions compared to older "simpler" compilers and compared to SQL. Are these valid complaints? Even if some compiler like a C compiler is modestly more "efficient" (whatever that means on this high of a level without seeing code) would you want to write applications in C over C# or Java? Is comparing an OO compiler to a SQL compiler/optimizer even valid?

• Demonstrate bad code to client?

  - by jtiger

  I have a new client that has asked me to do a redesign of their website, an ASP.NET Webforms application that was developed by another consultant. It seemed straight-forward (it never is) but I took a look at the code to make sure I knew what I was in for. This application was not written well. At all. It is extremely vulnerable to SQL Injection attacks, business logic is spread throughout the entire application, a lot of duplication, and dead end code that does nothing. On top of that, it keeps throwing exceptions that are being smothered, so it all appears to be running smoothly. My job is to simply update the html and css, but much of the html is being generated in business logic and would be a nightmare for me to sort everything out. My estimates on the redesign were longer than the client was aiming for, and they are asking why so long. How can I explain to my client just how bad this code is? In their mind, the application is running great and the redesign should be a quick one-off. It's my word against the previous consultant, so how can I actually give simple, concrete examples that a non-technical client would understand?

• Best way to use GIT to maintain web application template

  - by Darren

  I am a sole developer and I have a web application template that I have created in Visual Studio. I am using GIT for source control, but only on my development machine. Presently I have a master and I create branches for new features, merging them back in to the master as I complete the features. I am at a point now where I am ready to use the template for deployments, and of course I want to continue adding new features via branching/merging. My question is: what would be the typical/recommended way for me to create application deployments based on the master? Should I clone the repository into a new directory that is for a particular web application? Or should I also use branching to do project development based on the main project? The projects would never be merged back into the master. However, it would be nice if I could merge future features into the master and have the ability to incorporate them into previously completed projects if desired. For more specific details of my environment: I am using TortoiseGIT in Windows 7, Visual Studio 2012, ASP.NET Web Pages. Obviously the main differences between deployments would simply be differing pages, CSS files and jQuery scripts. I found this post as I was writing this one. In order to do this should I clone the master repository and checkout from it?

• I want to build a Virtual Machine, are there any good references?

  - by Michael Stum

  I'm looking to build a Virtual Machine as a platform independent way to run some game code (essentially scripting). The Virtual Machines that I'm aware of in games are rather old: Infocom's Z-Machine, LucasArts' SCUMM, id Software's Quake 3. As a .net Developer, I'm familiar with the CLR and looked into the CIL Instructions to get an overview of what you actually implement on a VM Level (vs. the language level). I've also dabbled a bit in 6502 Assembler during the last year. The thing is, now that I want¹ to implement one, I need to dig a bit deeper. I know that there are stack based and register based VMs, but I don't really know which one is better at what and if there are more or hybrid approaches. I need to deal with memory management, decide which low level types are part of the VM and need to understand why stuff like ldstr works the way it does. My only reference book (apart from the Z-Machine stuff) is the CLI Annotated Standard, but I wonder if there is a better, more general/fundamental lecture for VMs? Basically something like the Dragon Book, but for VMs? I'm aware of Donald Knuth's Art of Computer Programming which uses a register-based VM, but I'm not sure how applicable that series still is, especially since it's still unfinished? Clarification: The goal is to build a specialized VM. For example, Infocom's Z-Machine contains OpCodes for setting the Background Color or playing a sound. So I need to figure out how much goes into the VM as OpCodes vs. the compiler that takes a script (language TBD) and generates the bytecode from it, but for that I need to understand what I'm really doing. ¹ I know, modern technology would allow me to just interpret a high level scripting language on the fly. But where is the fun in that? :) It's also a bit hard to google because Virtual Machines is nowadays often associated with VMWare-type OS Virtualization...

• Network really slow with TL-WN951N wireless card

  - by Sam

  I literally just installed ubuntu and it seems to be working great except the network is deadly slow. I'm running a TL-WN951N wireless card which can download at about 600-700 KB/s in windows but in Ubuntu the max speed it seems to get is around 5KB/s. I guess I should note that my WAP is only wireless-G but like I said, I can get much better speeds in Windows. I'm testing the speeds by downloading files from here: http://mirror.internode.on.net/pub/test/ Anyone have any idea? I saw some people recommend downloading drivers and compiling them myself but I'm really really new to all of this so would appreciate someone babying me through it so I don't brick my computer!

• rkhunter: right way to handle warnings further?

  - by zuba

  I googled some and checked out two first links it found: http://www.skullbox.net/rkhunter.php http://www.techerator.com/2011/07/how-to-detect-rootkits-in-linux-with-rkhunter/ They don't mention what shall I do in case of such warnings: Warning: The command '/bin/which' has been replaced by a script: /bin/which: POSIX shell script text executable Warning: The command '/usr/sbin/adduser' has been replaced by a script: /usr/sbin/adduser: a /usr/bin/perl script text executable Warning: The command '/usr/bin/ldd' has been replaced by a script: /usr/bin/ldd: Bourne-Again shell script text executable Warning: The file properties have changed: File: /usr/bin/lynx Current hash: 95e81c36428c9d955e8915a7b551b1ffed2c3f28 Stored hash : a46af7e4154a96d926a0f32790181eabf02c60a4 Q1: Is there more extended HowTos which explain how to deal with different kind warnings? And the second question. Were my actions sufficient to resolve these warnings? a) To find the package which contains the suspicious file, e.g. it is debianutils for the file /bin/which ~ > dpkg -S /bin/which debianutils: /bin/which b) To check the debianutils package checksums: ~ > debsums debianutils /bin/run-parts OK /bin/tempfile OK /bin/which OK /sbin/installkernel OK /usr/bin/savelog OK /usr/sbin/add-shell OK /usr/sbin/remove-shell OK /usr/share/man/man1/which.1.gz OK /usr/share/man/man1/tempfile.1.gz OK /usr/share/man/man8/savelog.8.gz OK /usr/share/man/man8/add-shell.8.gz OK /usr/share/man/man8/remove-shell.8.gz OK /usr/share/man/man8/run-parts.8.gz OK /usr/share/man/man8/installkernel.8.gz OK /usr/share/man/fr/man1/which.1.gz OK /usr/share/man/fr/man1/tempfile.1.gz OK /usr/share/man/fr/man8/remove-shell.8.gz OK /usr/share/man/fr/man8/run-parts.8.gz OK /usr/share/man/fr/man8/savelog.8.gz OK /usr/share/man/fr/man8/add-shell.8.gz OK /usr/share/man/fr/man8/installkernel.8.gz OK /usr/share/doc/debianutils/copyright OK /usr/share/doc/debianutils/changelog.gz OK /usr/share/doc/debianutils/README.shells.gz OK /usr/share/debianutils/shells OK c) To relax about /bin/which as I see OK /bin/which OK d) To put the file /bin/which to /etc/rkhunter.conf as SCRIPTWHITELIST="/bin/which" e) For warnings as for the file /usr/bin/lynx I update checksum with rkhunter --propupd /usr/bin/lynx.cur Q2: Do I resolve such warnings right way?

• Caching strategies for entities and collections

  - by Rob West

  We currently have an application framework in which we automatically cache both entities and collections of entities at the business layer (using .NET cache). So the method GetWidget(int id) checks the cache using a key GetWidget_Id_{0} before hitting the database, and the method GetWidgetsByStatusId(int statusId) checks the cache using GetWidgets_Collections_ByStatusId_{0}. If the objects are not in the cache they are retrieved from the database and added to the cache. This approach is obviously quick for read scenarios, and as a blanket approach is quick for us to implement, but requires large numbers of cache keys to be purged when CRUD operations are carried out on entities. Obviously as additional methods are added this impacts performance and the benefits of caching diminish. I'm interested in alternative approaches to handling caching of collections. I know that NHibernate caches a list of the identifiers in the collection rather than the actual entities. Is this an approach other people have tried - what are the pros and cons? In particular I am looking for options that optimise performance and can be implemented automatically through boilerplate generated code (we have our own code generation tool). I know some people will say that caching needs to be done by hand each time to meet the needs of the specific situation but I am looking for something that will get us most of the way automatically.

• Ubuntu 12.04 - Brightness controls not working

  - by Juan Manuel Zolezzi Volpi

  Controls from "Brightness and Lock" were not working so I've tried a solution that involved changing grub, which I'm detailing below: # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 #GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX="quiet splash acpi_backlight=vendor" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" After doing this, the brightness control dissapeared like you can see at http://screencloud.net/img/screenshots/6b90d56604b70cc749a632d0bc005a20.png Any ideas? Would love to be able to configure Brightness or even use apps like F.lux to regulate it automatically. Edit: I've modified the following line to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=" and now the brightness controls are back, but whatever I change the brightness remains the same. Just in case I'm using Intel H77
