  • C++ Reference Book

    - by m00st
    Can someone list a C++ book that is just a reference to the standard library? I don't need a "learning c++" book just one that is a reference. Or at least official documentation or something? Googling only reveals "fan-site" reference.

  • The entire User Interface freezes/becomes unresponsive for up to 20 seconds

    - by user2400801
    I am a rails developer, using Ubuntu 13.10 installed on a Asus S550C Ultrabook (was a windows 8 machine originally) Every day I work with Sublime Text 2, Google Chrome, and Terminal (about 6 tabs open) The problem: clicking on the menu bar (eg File - Save) while using Sublime Text 2 will occasionally (eg almost always) make the ENTIRE COMPUTER freeze for up to 20 seconds. This occasionally happens when I go to log out / lock my computer. Sometimes it doesn't freeze completely but rather is just very sluggish and then recovers. I don't know if this is a problem with Sublime Text 2, or the Ubuntu 13.10 operating system. (Thanks for reading) Best Regards

  • Rails modeling for a user

    - by Trevor Hartman
    When building a rails app that allows a User to login and create data, is it best to setup a belongs_to :user association on every single model? For example, let's say a user can create Favorites, Colors and Tags. And let's say Favorites has_many :tags and Colors also has_many :tags. Is it still important for Tags to belong_to :user assuming the User is the only person who has authority to edit those tags? And a similar question along the same lines: When updating data in FavoritesController, I've come to the conclusion that you perform CRUD operations by always doing something like User.favorites.find(params[:id].update_attributes(param[:favorite]) so that they can definitely only update models that belong to them. Right?

  • Windows 7 hangs after longer inactivity of user

    - by scooby37
    I have serveral PCs running Windows 7 in different falvors (32- / 64-bit / Professional / Ultimate / ATI / Nvidia) - they all have one problem in common... ...if I don't work on any of them for a longer time and the screen goes off as it should be (all default settings!) they sometimes go into some kind of sleep mode where I get to see the desktop or whatever I did before leaving after moving the mouse or pressing a key - but nothing reacts for a different amount of time from serveral seconds to serveral minutes! Any hint that helps solving this anoying problem would be very welcome ;-)

  • Ubutu Server Edition: useful for the home user?

    - by D Connors
    My question is simple. What (if anything) does Ubuntu Server Edition have to offer to home users? This question is mostly out of curiosity really, but I like asking. I've got a home network set up here with some 6 to 7 machines (most Windows, one Linux). And I was wondering how useful would it be to have a dedicated computer in my house running Ubuntu Server full time. We've had an awful experience with file sharing so far, would it simplify file sharing/transferring? Would I be able to limit the internet bandwidth granted to each PC? Would I be able to monitor in/out internet traffic (both real time and monthly statistics)? Last, and most important, if I'm completely off as to what Ubuntu Server actually is, please say so. I am completely new to it.

  • Where did "Open with" (user defined command) go?

    - by MiStr
    I'm now using Ubuntu 12.04. In earlier versions you could associate a filetype with a specific command (e.g. self-compiled binary) by selecting "Open with" in the file's properties and select the command by providing the file path manually if it wasn't already in the list of applications. Is this possibility gone? The only way I found now is to create .desktop files and edit the mimetypes via an text editor.

    - by Michel
    hi, i have a date in this format : dd.mm.yyyy when i instantiate a javascript date with it, it gives me a NaN in c# i can specify a dateformat, to say: here you have my string, it's in this format, please make a Datetime of it. is this possible in javascript too, and if not, is there an easy way? i would prefer not to use a substring for day, substring for month etc. because my method must also be capable of german, italian, english etc dates.

  • Cannot change User Accounts settings

    - by eimmy
    I recently changed the name of the administrator and turned off passwords then clicked lock. After some time, I decided to add a password so I clicked on unlock and it's prompting me to enter a password. I tried typing the old password and it didn't accepted it. I also tried to set password and keys as "set to default" but still nothing happened. Now I'm stuck and can't get to change the administrator settings. I did my research but nothing seems to work. Please help.

  • Windows 7 user limitation

    - by Eildosa
    I just installed Windows 7 pro x64 from Dreamspark (MSDNAA). But i can't figure out how to configure it. 1/ When I want to acces some folders a pop up show up and tells me "that I need administrator acces to do it" I click the "continue" button and I can go inside the folder. What was even the point in showing me this pop up? how can I remove it? 2/ In some folder when I do a right clic I can only create a new folder, not a new text file, not a rar, nothing. In the same folder I also cannot extract RAR (by doing right clic, extract here) Any Idea how to get back full control? Thanks.

    - by Dano007
    Using the following html, css,jquery, js, what would be the best approach to achieving this. A visitor hits the website. The website page is displaying html and a css3 animation. The visitor is given the option to enter text freely into a text box, they enter an email address and hit send. The person receiving the message gets an email with a link, when they click the link it takes them to the webpage with the animation and the custom message their friend entered. Is this easy to achieve, what would be the best approach? anyone know of existing code I could use? Thanks

  • VCS for single user using file sync service

    - by StackUnder
    I'm trying to setup a version control for my one man project. My project files are in sync thanks to live mesh (but I could be using dropbox for that matter), between my laptop, my home pc and my office pc. I'm now using Netbeans with local file history. Sometimes it helps to revert to a previous state of one file. But imagine a situation when multiple files have problems. Correct me if I'm wrong but I would have to go to every file and revert to previous "safe" state. I don't like this approach, so I'm considering using a version control between SVN and GIT. I have some previous experience with SVN (TortoiseSVN) and I know that I can create a file:// repo. So, what a want to do is setup a VCS inside my synced folder just to have the ability to "revert" to a previous version if something goes wrong. Since everything's been synced to all computers, I wouldn't ever need to run an update. The file tree organization would be the following: C:...\SyncedFolder\MyProject\ Inside MyProject folder are all the project files plus a directory that has SVN or GIT info of my project (the repo/master). What VCS is best for this situation: SVN or GIT? Does SVN need to store all files from HEAD revision, thus "duplicating" all my project inside my synced folder? Does GIT eliminates this problem? Is this the best approach?

  • User Interface expected behavior

    - by Sn3akyP3t3
    I've encountered more than a few instances where a question arose from a desired change in a website page went against what I would describe as "expected behavior". One such recent request was to convert tab selection from what a tab typically does into a url redirect. I'm looking for guidance on where to turn to when these sorts of problems arise. Does the W3C cover these topics or are they left to the imagination of the web designer?

  • DDD: MailService.SendNotificationToUser() or User.Notify()?

    - by cfs
    I seem to stumble on problem after problem giving my entities behavior. I have a system where a user gets a notification when someone comments his article. Right now it is via an e-mail. I'm struggeling how to implement this the DDD way. Option 1 User entity has a Notify method: User.Notify() The method uses C# built in classes to send an e-mail notification via e-mail The problem with having this in the domain is that it is technology spesific, and how a user is notified might change in the future. I feel this belongs to infrastructure, but how then can a user have behavior? Option 2 I create a Service: NotificationService.Notify(User) The Service uses C# built in classes to send an e-mail The pro is that the service could be an Application Service, and as far as I know an application service can use the infrastructure and call things like the System.Net.Mail and repositories for that sake. How would you implement this?

  • SQL Server Master class winner

    - by Testas
     The winner of the SQL Server MasterClass competition courtesy of the UK SQL Server User Group and SQL Server Magazine!    Steve Hindmarsh     There is still time to register for the seminar yourself at:  www.regonline.co.uk/kimtrippsql     More information about the seminar     Where: Radisson Edwardian Heathrow Hotel, London  When: Thursday 17th June 2010  This one-day MasterClass will focus on many of the top issues companies face when implementing and maintaining a SQL Server-based solution. In the case where a company has no dedicated DBA, IT managers sometimes struggle to keep the data tier performing well and the data available. This can be especially troublesome when the development team is unfamiliar with the affect application design choices have on database performance. The Microsoft SQL Server MasterClass 2010 is presented by Paul S. Randal and Kimberly L. Tripp, two of the most experienced and respected people in the SQL Server world. Together they have over 30 years combined experience working with SQL Server in the field, and on the SQL Server product team itself. This is a unique opportunity to hear them present at a UK event which will: Debunk many of the ingrained misconceptions around SQL Server's behaviour    Show you disaster recovery techniques critical to preserving your company's life-blood - the data    Explain how a common application design pattern can wreak havoc in the database Walk through the top-10 points to follow around operations and maintenance for a well-performing and available data tier! Please Note: Agenda may be subject to change  Sessions Abstracts  KEYNOTE: Bridging the Gap Between Development and Production    Applications are commonly developed with little regard for how design choices will affect performance in production. This is often because developers don't realize the implications of their design on how SQL Server will be able to handle a high workload (e.g. blocking, fragmentation) and/or because there's no full-time trained DBA that can recognize production problems and help educate developers. The keynote sets the stage for the rest of the day. Discussing some of the issues that can arise, explaining how some can be avoided and highlighting some of the features in SQL 2008 that can help developers and DBAs make better use of SQL Server, and troubleshoot when things go wrong.   SESSION ONE: SQL Server Mythbusters  It's amazing how many myths and misconceptions have sprung up and persisted over the years about SQL Server - after many years helping people out on forums, newsgroups, and customer engagements, Paul and Kimberly have heard it all. Are there really non-logged operations? Can interrupting shrinks or rebuilds cause corruption? Can you override the server's MAXDOP setting? Will the server always do a table-scan to get a row count? Many myths lead to poor design choices and inappropriate maintenance practices so these are just a few of many, many myths that Paul and Kimberly will debunk in this fast-paced session on how SQL Server operates and should be managed and maintained.   SESSION TWO: Database Recovery Techniques Demo-Fest  Even if a company has a disaster recovery strategy in place, they need to practice to make sure that the plan will work when a disaster does strike. In this fast-paced demo session Paul and Kimberly will repeatedly do nasty things to databases and then show how they are recovered - demonstrating many techniques that can be used in production for disaster recovery. Not for the faint-hearted!   SESSION THREE: GUIDs: Use, Abuse, and How To Move Forward   Since the addition of the GUID (Microsoft’s implementation of the UUID), my life as a consultant and "tuner" has been busy. I’ve seen databases designed with GUID keys run fairly well with small workloads but completely fall over and fail because they just cannot scale. And, I know why GUIDs are chosen - it simplifies the handling of parent/child rows in your batches so you can reduce round-trips or avoid dealing with identity values. And, yes, sometimes it's even for distributed databases and/or security that GUIDs are chosen. I'm not entirely against ever using a GUID but overusing and abusing GUIDs just has to be stopped! Please, please, please let me give you better solutions and explanations on how to deal with your parent/child rows, round-trips and clustering keys!   SESSION 4: Essential Database Maintenance  In this session, Paul and Kimberly will run you through their top-ten database maintenance recommendations, with a lot of tips and tricks along the way. These are distilled from almost 30 years combined experience working with SQL Server customers and are geared towards making your databases more performant, more available, and more easily managed (to save you time!). Everything in this session will be practical and applicable to a wide variety of databases. Topics covered include: backups, shrinks, fragmentation, statistics, and much more! Focus will be on 2005 but we'll explain some of the key differences for 2000 and 2008 as well. Speaker Biographies     Kimberley L. Tripp Paul and Kimberly are a husband-and-wife team who own and run SQLskills.com, a world-renowned SQL Server consulting and training company. They are both SQL Server MVPs and Microsoft Regional Directors, with over 30 years of combined experience on SQL Server. Paul worked on the SQL Server team for nine years in development and management roles, writing many of the DBCC commands, and ultimately with responsibility for core Storage Engine for SQL Server 2008. Paul writes extensively on his blog (SQLskills.com/blogs/Paul) and for TechNet Magazine, for which he is also a Contributing Editor. Kimberly worked on the SQL Server team in the early 1990s as a tester and writer before leaving to found SQLskills and embrace her passion for teaching and consulting. Kimberly has been a staple at worldwide conferences since she first presented at TechEd in 1996, and she blogs at SQLskills.com/blogs/Kimberly. They have written Microsoft whitepapers and books for SQL Server 2000, 2005 and 2008, and are regular, top-rated presenters worldwide on database maintenance, high availability, disaster recovery, performance tuning, and SQL Server internals. Together they teach the SQL MCM certification and throughout Microsoft.In their spare time, they like to find frogfish in remote corners of the world.   Speaker Testimonials  "To call them good trainers is an epic understatement. They know how to deliver technical material in ways that illustrate it well. I had to stop Paul at one point and ask him how long it took to build a particular slide because the animations were so good at conveying a hard-to-describe process." "These are not beginner presenters, and they put an extreme amount of preparation and attention to detail into everything that they do. Completely, utterly professional." "When it comes to the instructors themselves, Kimberly and Paul simply have no equal. Not only are they both ultimate authorities, but they have endless enthusiasm about the material, and spot on delivery. If either ever got tired they never showed it, even after going all day and all week. We witnessed countless demos over the course of the week, some extremely involved, multi-step processes, and I can’t recall one that didn’t go the way it was supposed to." "You might think that with this extreme level of skill comes extreme levels of egotism and lack of patience. Nothing could be further from the truth. ... They simply know how to teach, and are approachable, humble, and patient." "The experience Paul and Kimberly have had with real live customers yields a lot more information and things to watch out for than you'd ever get from documentation alone." “Kimberly, I just wanted to send you an email to let you know how awesome you are! I have applied some of your indexing strategies to our website’s homegrown CMS and we are experiencing a significant performance increase. WOW....amazing tips delivered in an exciting way!  Thanks again”
