• What are some good tips for a developer trying to design a scalable MySQL database?

  - by CFL_Jeff

  As the question states, I am a developer, not a DBA. I have experience with designing good ER schemas and am fairly knowledgeable about normalization and good schema design. I have also worked with data warehouses that use dimensional modeling with fact tables and dim tables. However, all of the database-driven applications I've developed at previous jobs have been internal applications on the company's intranet, never receiving "real-world traffic". Furthermore, at previous jobs, I have always had a DBA or someone who knew much more than me about these things. At this new job I just started, I've been asked to develop a public-facing application with a MySQL backend and the data stored by this application is expected to grow very rapidly. Oh, and we don't have a DBA. Well, I guess I am the DBA. ;) As far as designing a database to be scalable, I don't even know where to start. Does anyone have any good tips or know of any good educational materials for a developer who has been sort of shoved into a DBA/database designer role and has been tasked with designing a scalable database to support an application like this? Have any other developers been through this sort of thing? What did you do to quickly become good at this role? I've found some good slides on the subject here but it's hard to glean details from slides. Wish I could've attended that guy's talk. I also found a good blog entry called 5 Ways to Boost MySQL Scalability which had some good information, though some of it was over my head. tl;dr I just want to make sure the database doesn't have to be completely redesigned when it scales up, and I'm looking for tips to get it right the first time. The answer I'm looking for is a "list of things every developer should know about making a scalable MySQL database so your application doesn't perform like crap when the data gets huge".

• How to disable the text shadow in plasma widgets KDE 4.6?

  - by piedro

  I just switched completely to Kubuntu for the sake of the more suitable applications for my purposes and their overall integration in the system. But I'm not very happy with all those desktop effects and tranparent looks everywhere. Some things a matter of taste I guess. Some things just unbearable for me having weak eyes. One of them is that about every light theme seems to be using a text shadow effect on the plasma widgets. A white "spilled milk" effect underneath dark text on light grey or glassy background. Drives my eyes nuts! I can remove this effect on the desktop folder by unselecting "shadow" as text effect. I can't find any way to switch it of in the panel and the plasma widgets. My second, related question is, is there a plasma theme matching the oxygen look of the default desktop in light colors that uses the same colors as the ones chosen in the KDE color settings, - simple, opaque, no effects, gnome-like? Plz help someone! thx, piedro

• The advantages & disadvantages to be had from using a Web Framework?

  - by JHarley1

  Hello, This question is focused on extracting the advantages and disadvantages of using Web based Frameworks: such as Cake PHP, Zend, jQuery, ASP.NET). This question is completely language agnostic. Let me start with the notion of "Standing on the shoulders of Giants". Advantages: Empowers Developers - by taking features that would have previously have taken 100's of lines of code and compressing them into one simple function call empowers developers to integrate more complex features into their Web Sites. Allow for Quicker development of applications - this is very relevant for people that need websites created in a very small window (has anyone any examples of this?) Lower Costs - allows programmers to pass cost savings onto the customer, a whole new range of customers generated that wanted a website but previously could not afford the higher development costs. Disadvantages: Lost Understanding - by relying on the features of a framework a developer is in danger of loosing understanding on how things work (underneath the hood). The configuration cliff - once you go further than the configuration of your framework your productivity drops right off, it can be difficult to implement features outside of a frameworks configuration. Developer tramlines - you (the developer) has to do things the way that the developer want you to do things. Security issues - giving people these tools to develop professional looking websites fast is a potential risk, people can quickly create professional looking websites for fraudulent companies. I wonder what people make of my points, and whether any body disagrees with them? Also if people have additional points I would be grateful. Many Thanks, J

• Offshoring: does it ever work?

  - by DanSingerman

  I know there has been a fair amount of discussion on here about outsourcing/offshoring, and the general opinion seems to be that at best it is difficult, and at worst it fails. I have direct experience of offshoring myself; a previous company where I was a dev manager wanted to send some development offshore, and we ran a pilot scheme to see how well it would work. Of course it was a complete failure, although it is not completely clear to me whether this was down to the offshore devs being less talented, the process, or other factors (no doubt it was really a combination). I can see as a business how offshoring looks attractive (much lower day rate), but as far as I can see, the only way it could possibly work is if you do exceptionally detailed design up front, with incredibly detailed specifications; and by the time you have invested in producing that, you have probably spent as nearly as much as if you had written the actual code locally (which I think is an instance of No Silver Bullet) So, what I want to know is, does anyone here have any experience of offshoring actually working ever? Especially if there are any success stories of it working in a semi-agile way? I know there are developers here from all over the World; has anyone worked on an offshore project they consider successful?

• Need help understanding Mocks and Stubs

  - by Theomax

  I'm new to use mocking frameworks and I have a few questions on the things that I am not clear on. I'm using Rhinomocks to generate mock objects in my unit tests. I understand that mocks can be created to verify interactions between methods and they record the interactions etc and stubs allow you to setup data and entities required by the test but you do not verify expectations on stubs. Looking at the recent unit tests I have created, I appear to be creating mocks literally for the purpose of stubbing and allowing for data to be setup. Is this a correct usage of mocks or is it incorrect if you're not actually calling verify on them? For example: user = MockRepository.GenerateMock<User>(); user.Stub(x => x.Id = Guid.NewGuid()); user.Stub(x => x.Name = "User1"); In the above code I generate a new user mock object, but I use a mock so I can stub the properties of the user because in some cases if the properties do not have a setter and I need to set them it seems the only way is to stub the property values. Is this a correct usage of stubbing and mocking? Also, I am not completely clear on what the difference between the following lines is: user.Stub(x => x.Id).Return(new Guid()); user.Stub(x => x.Id = Guid.NewGuid());

• I installed ubuntu, the installer told me to reboot afterwards. I dd, and now linux wont boot

  - by mandy

  Im trying to dual boot between mac 10.6.8 and ubuntu 11.10. I have a macbook pro 8,1. So i installed from a 10.04 disk because the install window makes more sense to me, and it doesnt give me errors or anything. Also, any versions of ubuntu after that dont boot from disk for whatever reason. (i think its having to do with the efi boot thing. i have to get ubuntu 11.10 to boot from a usb with folders bootefiboot.iso) Then my plan after that was after the ubuntu 10.04 install took care of all the swap and stuff for me without being messy, to upgrade to 11.10. So here i have 10.04 booting successfully back and forth from mac osx no problem. I put in my 11.10 usb and the installer gives me the option to "update 10.04 to 11.10" bingo, jackpot, thats what i want. Everything proceeds as normal, as EVERY OTHER install of ubuntu i have ever done, then the installer finishes and says HEY! im finished! Continue testing or reboot now! So i reboot, and what do i get??? A black screen that says the file system isnt found, to enter a boot disk and press any key. WHAT THE HELL????? so i boot the 11.10 installer again from usb, and select "erase 11.10 and install 11.10", installer proceeds normally, and asks me to reboot. I reboot and get the SAME THING. Please, someone, help me get this right here. This is my first time actually dual booting between mac and linux. Usually i just wipe off osx completely and install ubuntu but i actually need to keep my mac partition this time. I have successfully installed 11.10 on this machine before, but that was when i did a clean install. Help?

• How far should one take e-mail address validation?

  - by Mike Tomasello

  I'm wondering how far people should take the validation of e-mail address. My field is primarily web-development, but this applies anywhere. I've seen a few approaches: simply checking if there is an "@" present, which is dead simply but of course not that reliable. a more complex regex test for standard e-mail formats a full regex against RFC 2822 - the problem with this is that often an e-mail address might be valid but it is probably not what the user meant DNS validation SMTP validation As many people might know (but many don't), e-mail addresses can have a lot of strange variation that most people don't usually consider (see RFC 2822 3.4.1), but you have to think about the goals of your validation: are you simply trying to ensure that an e-mail address can be sent to an address, or that it is what the user probably meant to put in (which is unlikely in a lot of the more obscure cases of otherwise 'valid' addresses). An option I've considered is simply giving a warning with a more esoteric address but still allowing the request to go through, but this does add more complexity to a form and most users are likely to be confused. While DNS validation / SMTP validation seem like no-brainers, I foresee problems where the DNS server/SMTP server is temporarily down and a user is unable to register somewhere, or the user's SMTP server doesn't support the required features. How might some experienced developers out here handle this? Are there any other approaches than the ones I've listed? Edit: I completely forgot the most obvious of all, sending a confirmation e-mail! Thanks to answerers for pointing that one out. Yes, this one is pretty foolproof, but it does require extra hassle on the part of everyone involved. The user has to fetch some e-mail, and the developer needs to remember user data before they're even confirmed as valid.

• How do I draw a 2d plane and rotate camara (To be a board) in a 3d XNA game?

  - by Mech0z

  I am trying to create a simple board game, but the 3d part of this is really killing me. From what I can gather I have created a plane, but it never moves even though I turn the camara, but that partially makes sense as I only turn the camara with a 3d model, but in my head that makes 0 sense, in my head if I turn the camara it should affect ALL my models? But with this code the camara only "cares" about the 3d cylinder, the plane is just completely still private void OnDraw(object sender, GameTimerEventArgs e) { SharedGraphicsDeviceManager.Current.GraphicsDevice.Clear(Color.CornflowerBlue); foreach (ModelMesh mesh in cylinderModel.Meshes) { foreach (BasicEffect effect in mesh.Effects) { //effect.World = Matrix.CreateRotationX((float)e.TotalTime.TotalSeconds * 2); effect.View = Matrix.CreateLookAt(cameraPosition, Vector3.Zero, Vector3.Up); effect.Projection = Matrix.CreatePerspectiveFieldOfView(MathHelper.ToRadians(45.0f), aspectRatio, 1.0f, 10000.0f); effect.EnableDefaultLighting(); } mesh.Draw(); } //cameraPosition.Z -= 5.0f; _effect.World = Matrix.CreateRotationZ((MathHelper.ToRadians(((float)e.TotalTime.Milliseconds / 2) % 360))); foreach (EffectPass pass in _effect.CurrentTechnique.Passes) { pass.Apply(); SharedGraphicsDeviceManager.Current.GraphicsDevice.DrawUserPrimitives(PrimitiveType.TriangleStrip, _vertices, 0, 1, VertexPositionColor.VertexDeclaration); } } Is there a way to get the camara to affect all models?

• "Misaligned partition" - Should I do repartition (how?)

  - by RndmUbuntuAmateur

  Tried to install Ubuntu 12.04 from USB-stick alongside the existing Win7 OS 64bit, and now I'm not sure if install was completely successful: Disk Utility tool claims that the Extended partition (which contains Ubuntu partition and Swap) is "misaligned" and recommends repartition. What should I do, and if should I do this repartition, how to do it (especially if I would like not to lose the data on Win7 partition)? Background info: A considerably new Thinkpad laptop (UEFI BIOS, if that matters). Before install there were already a "SYSTEM_DRV" partition, the main Windows partition and a Lenovo recovery partition (all NTFS). Now the table looks like this: SYSTEM_DRV (sda1), Windows (sda2), Extended (sda4) (which contains Linux (sda5; ext4) and Swap (sda6)) and Recovery (sda3). Disk Utility Tool gives a message as follows when I select Ext: "The partition is misaligned by 1024 bytes. This may result in very poor performance. Repartitioning is suggested." There were couple of problems during the install, which I describe below, in the case they happen to be relevant. Installer claimed that it recognized existing OS'es fine, so I checked the corresponding option during the install. Next, when it asked me how to allocate the disk space, the first weird thing happened: the installer give me a graphical "slide" allocate disk space for pre-existing Win7 OS and new Ubuntu... but it did not inform me which partition would be for Ubuntu and which for Windows. ..well, I decided to go with the setting installer proposed. (not sure if this is relevant, but I guess I'd better mention it anyway - the previous partition tools have been more self-explanatory...) After the install (which reported no errors), GRUB/Ubuntu refused to boot. Luckily this problem was quite straightforwardly resolved with live-Ubuntu-USB and Boot-Repair ("Recommended repair" worked just fine). After all this hassle I decided to check the partition table "just to be sure"- and the disk utility gives the warning message I described.

• Cry Engine 3 vs UDK

  - by Daniele Riccardelli

  I'm new here and I hope that other people may find this question interesting. Me and a bunch of guys from my University are thinking about getting started in game development, but, even though the game design is kind of ready, we are stucked at the point "which Engine should we choose". At first, we were thinking about Unity3D Free, in particular because we are pretty familiar with C# and, even better, it's completely free, but on the other hand there are some cons like no dynamic shadowing that make the realization of our game kinda hard. So, we are thinking about moving either to UDK or Cry Engine, since they are not as expensive as Unity3D Pro (at least before the game deployment) . The thing we are worried the most, though, is that we are kind of scared about the support for team work(i mean, that we might find it hard to coordinate our efforts without software support), since in Unity3D the team features are part of purchasable content, and we are not interested in paying that much for a project we are not even sure we can complete. So, finally, I hope one of you knows the mentioned engines enough to give us a tip telling which one offers better team features and is advisable for guys that have barely worked before on videogames but have good object oriented programming skills. Probably might be helpful for your suggestion, if i say that our game is an exploration game. Thanks to anybody who's going to answer.

• I just received a complaint from a user of the website I maintain. Should I do anything?

  - by Chris

  I was sent sent a large wall of text from a user of the website I maintain at my job. They are clearly upset for having to deal with a horribly outdated web application that has not seen any serious updates in over 6+ years. No refactoring has been done, the code quality is terrible, the security unchecked, policy compliances ignored, in addition to being ugly and frankly embarrassing. Keep in mind this is a small business but the website is used by hundreds daily. I'm one of two programmers there, and I've been working there for two years. This person says they are about my age (22) and understand technology (but can't use proper grammar). The complaint mentioned awkward pages and actions on the website, but they don't even have a clue as to the depth of the flaws in this website. Now, I would love to honestly tell them that there's a lot wrong with this company and that this application was built when we were in high school. And that while it's not my fault that the website is terrible, I'm the one in position to fix it. But on the other hand, I could just say nothing and ignore it. Would doing this publicly have any advantage to future employees (showing integrity) or would it just be a completely pointless mistake? Odds are, even if I respond only that one person will ever read it. Regardless, I'm probably just going to ignore it and continue starting my project to refactor the website.

• Unable to detect windows hard drive while running Ubuntu 12.04 from USB

  - by eapen jacob

  I am completely new to Ubuntu. I experimented with Ubuntu 12.04 by running it from a USB drive, in-order to recover files from my hard disc. History: My laptop is an IBM R60 running windows 7. Suddenly it gave me an error stating "error 2100 - Hard drive initialization error". I have read all the forums and most of them suggested that I remove and replace my HDD and that did not work. And one site suggested to try using Ubuntu to recover files. I booted my system from USB, and once Ubuntu came up, I choose "Try Ubuntu". It came up fine and I was able to surf ,and do other things, etc. I was unable to to access my files which are on the hard disc and "Attached Devices" is grayed out. 1- Is there any way to gain access to my hard disc to recover the files? How do I navigate to search for my files. 2- Is it just simply not possible if the hard disc themselves are not working? Is that why I`m unable to find the drives. I know its a very novice question, but hoping someone would help me out. Thank you, Eapen

• SQL to XML open data made simple

  - by drrwebber

  The perennial question for people is how to easily generate XML from SQL table content?  The latest CAM Editor release really tackles this head on by providing a powerful and simple toolset.  Firstly you can visually browse your SQL tables and then drag and drop from columns and tables into the XML structure editor.   This gives you a code-free method of describing the transformation you require.  So you do not need to know about the vagaries of XML and XSD schema syntax. Second you can map directly into existing industry domain XML exchange structures in the XML visual editor, again no need to wrestle with XSD schema, you have WYSIWYG visual control over what your output will look like. If you do not have a target XML structure and need to build one from scratch, then the CAM Editor makes this simple.  Switch the SQL viewer into designer mode, then take your existing SQL table and drag and drop it into the XML structure editor.  Automatically the XML wizard tool will take your SQL column names and definitions and create equivalent XML for you and insert the mappings. Simply save the structure template, and run the Open Data generator menu option, and your XML is built for you. Completely code-free template driven development. To see this in action, see our video demonstration links and then download the tools and samples and try it yourself.

• Should I be looking for developers with specific skill sets or generalists that need to learn?

  - by Lostsoul

  Thanks to the great help of this site and SO, I've been able to make a prototype of a software I want to sell but unfortunately although the prototype works I think my code quality is very low. I didn't use much OOP or design patterns so although my code is understandable to me, I think a normal developer would faint if they had to read it. So I wanted to hire a developer to make it a bit more better quality and improve some of my implementations of API's that I may have not done correctly. I'm having problems hiring a developer though. I have met 2 developers and had them read my software specs.The problem is, they lacked my business's domain knowledge(which is completely understandable and no biggie) but they also lacked knowledge of the underlying tech systems I used such as Hadoop, Hbase, Cuda, etc..I spent alot of time explaining map/reduce, bigtables and other technologies I used. I thought it was common knowledge because of my interactions with people on this site but the people I met with mentioned they never had to deal with these things so they didn't know it. My question is, for software projects that are hiring contractor developers is it a danger if the developer does not have experience with the underlying technologies? or can a general developer who is accomplished in another area realistically pick up new technologies? I did a very very quick back of envelope calculation and I think the upfront costs would be similar if I hire a student or developer with no experience in my technologies who will work many hours versus hiring a highly experienced developer who charges double but finishes in half the time but what other risks should I be considering or worried about? Also, should if I do hire a generalist, should I be paying for the time it takes them to learn hadoop or cuda if they are contractors(seems to make business sense but not sure how fair it is to them if they do not use the skill again). I'm a bit confused so any suggestions would be great.

• When running Minecraft with OpenJDK, my keyboard becomes unresponsive?

  - by Mochan

  I recently downloaded Minecraft with the .jar format and had it running on my computer not so long ago. Now that I'm using my desktop instead of laptop temporarily, I want it to run. On my laptop it was a tremendous hassle to get OpenJDK to even run the application without it going black and I don't have that problem on my desktop. However, when I run the application on desktop, my keyboard becomes unresponsive and doesn't type at all. This is a really big problem because I can't play the game as it requires keyboard interaction. It works as normal on my laptop though and it works perfectly. But now on the desktop it's completely useless. I don't know if there's like a keyboard driver I'm missing, but there shouldn't be because the keyboard runs flawlessly everywhere else. I'm using OpenJDK 6 because the 7 has the same 'black screen' I mentioned. So I need this to work within OpenJDK 6. Thanks so much in advance and I'll try to specify as many details as I can.

• Interesting fault attempting to install Ubuntu 12.0.4.3 OR 13.10 on MSI GS70 2OD-001US

  - by cjaredrun

  Attempting to install Ubuntu on an MSI GS70 2OD-001US notebook pre-installed with Windows 8. For the record this is what I have attempted: All cases were attempted with Ubuntu 12.0.4.3 AND 13.10 images via USB drives Case 1 - Attempt no changes and simply boot from USB Result: It seems to want to work initially. The Ubuntu logo pops up and the dots start moving. After a few seconds the dots freeze and this screen is shown: http://i.imgur.com/C7pyMRk.jpg Case 2 - Start playing with BIOS - In Windows turning off fast boot - In BIOS turning off Secure boot - In BIOS turning off UEFI and selecting LEGACY Result: Brought to a black screen with a - blinking at me. Case 3 - Alternating BIOS settings - In Windows turning off fast boot - In BIOS turning off Secure boot - in BIOS turning off UEFI and selecting UEFI with CSM Result: Brought to a black screen no other indication of change. It's pretty frustrating to feel locked out of a laptop that I have paid good money for, I'm sure I am not alone in that case. It does however appear that there has been some success, so I am hopeful that someone might be able to help me. FYI: Dual booting is not necessary for me, if that helps at all... I'm not sure if this is a reasonable option, but if I completely wipe clean the hdds, no particle of Windows at all, would this still be a problem? Also would opening up the laptop and replacing the HDDS with brand new ones be a solution as well? Thanks for any input or suggestions.

• IIS 7 SSO stops working during high CPU load? [migrated]

  - by DanB

  On our IIS7 site (Windows 2008 Server), we have set up single sign-on (SSO). It seems to work fine most of the time, but when the CPU load becomes high, SSO authentication completely stops working. I did some research and tried this suggestion to increase the max number of worker processes in the default app pool, but the increase did not help. Some details: The site is a WordPress blog. The server has plenty of RAM (2 GB) and free disk space. SSO is achieved by putting a copy of the WordPress login page (wp-login.php) into a subfolder below the root that has anonymous authentication disabled, and then redirecting the browser to it. This was the recommendation of Microsoft given to our consultants. To increase CPU load for testing, I have three scripts hit the home page simultaneously, over and over. This drives CPU to 100%. When these scripts are running, SSO authentication simply doesn't happen. As soon as I stop the scripts, SSO works again. (I should mention that the SSO problem also happens when many users visit the site at once....) The WordPress database process (mysqld) is not stressed at all by the scripts. I would be happy to provide further diagnostics. Any help appreciated!

• Calculating distance from viewer to object in a shader

  - by Jay

  Good morning, I'm working through creating the spherical billboards technique outlined in this paper. I'm trying to create a shader that calculates the distance from the camera to all objects in the scene and stores the results in a texture. I keep getting either a completely black or white texture. Here are my questions: I assume the position that's automatically sent to the vertex shader from ogre is in object space? The gpu interpolates the output position from the vertex shader when it sends it to the fragment shader. Does it do the same for my depth calculation or do I need to move that calculation to the fragment shader? Is there a way to debug shaders? I have no errors but I'm not sure I'm getting my parameters passed into the shaders correctly. Here's my shader code: void DepthVertexShader( float4 position : POSITION, uniform float4x4 worldViewProjMatrix, uniform float3 eyePosition, out float4 outPosition : POSITION, out float Depth ) { // position is in object space // outPosition is in camera space outPosition = mul( worldViewProjMatrix, position ); // calculate distance from camera to vertex Depth = length( eyePosition - position ); } void DepthFragmentShader( float Depth : TEXCOORD0, uniform float fNear, uniform float fFar, out float4 outColor : COLOR ) { // clamp output using clip planes float fColor = 1.0 - smoothstep( fNear, fFar, Depth ); outColor = float4( fColor, fColor, fColor, 1.0 ); } fNear is the near clip plane for the scene fFar is the far clip plane for the scene

• Unity is broken after upgrading to 12.10 (Optimus laptop)

  - by SyS

  I upgraded to GNU/Linux Ubuntu 12.10 but have been unable to use Unity properly afterwards. Indeed, I encountered the exact same problem as a lot of people: the Unity side and top bars are not displaying, although in my case, Unity seems completely broken, as I can't even right-click. However, in my case, it's worth noticing that I have an Optimus laptop with a Nvidia graphics card (GeForce GT 540M). Bumblebee and its 'optirun' command is working just fine, as usual, after the upgrade. I tried several things, as resetting Compiz and Unity (with the command 'setside unity') -- which works but I have to do it everytime I boot and it resets all my settings -- updating/reinstalling/reconfiguring my Nvidia drivers as well as bumblebee, trying with Nouveau drivers instead of nvidia-current, check if linux-headers-generic were installed (they were). However, I couldn't reset xorg.conf files as they're just not there. There is neither xorg.conf file, nor its backup in /etc/X11. I think this is where the problem comes from, although I'm far from an expert. Maybe retrieving a xorg.conf file will fix this mess, but I have no idea how to do that. I'm just tired and don't know what to do. So, here I am, begging for your help.

• Web hosting company basically forces me to use their domain name [closed]

  - by Jinx

  I've recently stumbled upon an unusual problem with one of hosting companies called giga-international.com. Anyway, I've ordered com.hr domain from Croatian domain name registration company, and my client insisted on using this host provider as couple of his friends already are hosted with them. I thought something was fishy when the first result on Google for Giga International was this little forum rant instead of their webpage. When I was checking their services they listed many features etc... space available, bandwidth etc. I just wanted to check how much ram do I get for my PHP scripts so I emailed them, and they told me that was company secret. Seriously? Anyway, since my client still insisted on hosting with them I've bought their Webspace package. During registration I had to choose free domain name because I couldn't advance registration without it. Nowhere was said, not even in general terms and conditions that I wouldn't be able to change that domain name. At least not for double the price of domain name per year. They said I can either move my domain name over to them (and pay them domain registration), or pay them 1 Euro per month for managing a DNS entry. On any previous hosting solution I was able to manage my domain names just by pointing my domain to their name servers, and this is something completely new and absurd for me. They also said that usual approach is not possible because of security and hardware limitations. I'd like to know what you guys think about this case, and should I report, and where should I report this case. In short. They forced me to register free domain name which doesn't suit my needs in order to register for their webspace package, and refuse to change domain name for my account until I either transfer domain to them or pay them DNS management which costs double the price of the domain name per year.

• How should I approach learning programming languages?

  - by gcc

  I am a student of computer engineering. I have never done any programming before, and as you can understand, I don't know how to study it or how to make my own programs. My English is weak [edited for clarity - ed], and so if you don't like the choices I list, please feel free to provide others. How should I study? How should I learn programming languages? Study completely from a book. Don't study from a book, just try writing code. A mix of the two; study from a book, then try writing code. Study half the book, then write the code by hand on paper. Listed to the teacher, then try to solve general problems (those not from any specific chapter). I have send that question to stackoverflow before when I am at first year.

• Making document storage in Sharepoint a breeze (leave the Web UI behind)

  - by deadlydog

  Hey everyone, I know many of us regularly use Sharepoint for document storage in order to make documents available to several people, have it version controlled, etc.  Doing this through the Web UI can be a real headache, especially when you have multiple documents you want to modify or upload, or when IE isn’t your default browser.  Luckily we can access the Sharepoint library like a regular network drive if we like. Open Sharepoint in Internet Explorer (other browsers don’t support the Open with Explorer functionality), navigate to wherever your documents are stored, choose the Library tab, and then click Open with Explorer. This will open the document storage in Explorer and you can interact with the documents just like they were on any other network drive J  This makes uploading large numbers of documents or directory structures super easy (a simple copy-paste), and modifying your files nice and easy. As an added bonus, you can drag and drop that location from the address bar in Explorer to the Favorites menu so that it’s always easily accessible and you can leave the Sharepoint Web UI behind completely for modifying your documents.  Just click on the new favorite to go straight to your documents.   You can even map this folder location as a network drive if you want to have it show up as another drive (e.g N: drive). I hope you found this as useful as I did

• ubuntu 12.04 LTS hangs on boot when external monitor is connected

  - by vladeta

  I have a problem with my fresh installed Ubuntu 12.04 LTS on my Dell M4600: nVidia quadro 2000M i7-2860 16GB ram 128GB SSD Dell/Samsung 750GB HDD IPS RGB laptop display When it is connected via DP++ to the external Dell U2311H monitor, it hangs on boot or when wakening from suspend. If I detach the DP cable it boots normally. I have tried all combinations that I have found, as adding to grub: "no splash", "boot=pci", "acpi=off", etc... I have also changed in nVidia X settings that external monitor is the primary one and also tried to delete monitor.xml file. There is no change it hangs each time after grub. It starts to load daemons then both screens are blank and then completely hangs with beep sound. What I discovered is if I detach the cable and wait for about 2 sec after grub starts booting and then physically connect DP cable while the Ubuntu is still booting everything works normally and I have a picture on my external screen while the laptop screen is off, just as I wanted. Do you maybe know how to solve this issue? Thank You.

• How can one-handed work in Ubuntu be eased?

  - by N.N.

  My right hand is temporarily immobilized and I would like to do some minor general work on my computer. Mostly web browsing, mailing and file and directory browsing and editing. For this I currently use Firefox, Thunderbird, Nautilus and the GNOME terminal (I have already asked a specific question about Emacs). Are there ways to ease such, or any other general, one-handed work in Ubuntu? I have found http://stackoverflow.com/questions/2391805/how-can-i-remain-productive-with-one-hand-completely-immobilized but that is not exactly what I am asking for. I want to ease whatever little time spent one-handed in Ubuntu and this is also interesting for situations where there is no injury involved, such as when one hand is occupied. I do realize I should avoid unnecessary strain. The main thing that is much slower one-handed is writing. Since I am only temporarily immobilized it seems to make no sense learn a new keyboard layout. I would be surprised if I managed to learn and become more effective with a new keyboard layout (than one-handed QWERTY) before I can use my other hand again. What I have already found: Sticky keys for making it easier to enter keyboard commands. When writing one-handed there are more cases of where it is useful to paste in phrases rather than to reenter them. It is easier to use Super+S rather than CtrlAlt+arrow keys to switch work space.
