• Where did ULSTraceLog go to in the SharePoint 2010 Logging Database?

  The Logging Database is one of the many new concepts that will make the life of many SharePoint administrators quite a bit more enjoyable. In SharePoint 2007 the Unified Logging System (ULS) logged all of its data to text files, typically found on your SharePoint server in 12\LOGS. We still have that in SharePoint 2010, but besides those text files, ULS can also write the data to a database! The advantages are obvious: easy to query, one central location for all servers in the farm, easy to build...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• SQLPASS Summit 2011 -- I'm going but not as a speaker

  - by NeilHambly

  This post is about my attempt and slight failure @ getting a presenting session @ this year’s SQLPASS Summit 2011 I had submitted for the 1st time 2 submissions (think we had max of 4 we could enter, but I was happy to go with just 2 this time, 1 I had already presented & 1 was nearly completed) My general session (75 minutes) the same session on “Waits” I had done @ SQLBits 8 back in Brighton last April, and a new 1/2 day 3.5 hours format which is a session I’m completing on SQLOS layer Well...(read more)

• Should I install SELinux to make my Ubuntu Web server more secure?

  - by Desmond Hume

  This wiki page on using SELinux with Ubuntu informs of the following: The Ubuntu-specific "selinux" and "selinux-policy-ubuntu" packages documented here have not received much attention since Karmic, and appear to be effectively broken in Precise. So does it make sense to even consider installing SELinux with the purpose of making a general-purpose Web server running on Ubuntu 12.04 more secure? What are the potential problems that SELinux can bring into an Ubuntu Web server?

• Stability of beta and daily-live

  - by Prateek

  I have some related questions: For 12.04 (and in general), are the beta releases more stable/less buggy than the daily builds? If the answer to 1 is yes, then if I install the beta and apt-get upgrade, will I remain at the "stability level" of the beta, or of the daily builds? At this point, is there any advantage to installing the beta over installing a daily image? (Background : I am debating whether to install 11.10 or 12.04 beta/daily on a new machine)

• When to mark a user story as done in scrum?

  - by Saeed Neamati

  There is a notion in scrum that emphasizes delivery of workable units at the end of each sprint. Each workable unit also maps directly of indirectly to a user story and when in new sprint PO introduces new PBI (new user stories), this means that practically team can't always go back to previous user stories to do the rest of the job, which in turn means that when you implement a user story, you should do it as complete as it's known to the team in that time, and you shouldn't forget anything (something like "I'm sorry, I've forgotten to implement validation for that input control" or "I didn't know that cross-browser check is part of the user story"). At the other hand, test, backward compatibility, acceptance criteria, deployment and more and more concepts come after each user story. So, when can team members know that the user story is done completely, not just for demo, and start a new one?

• Do I need to know servlets and JSP to learn spring or hibernate or any other java web frameworks?

  - by KyelJmD

  I've been asking a lot of people where to start learning java web development, I already know core java (Threading,Generics,Collections, a little experience with (JDBC)) but I do not know JSPs and servlets. I did my fair share of development with several web based applications using PHP for server-side and HTML,CSS,Javascript,HTML5 for client side. Most people that I asked told me to jump right ahead to Hibernate while some told me that I do not need to learn servlets and jsps and I should immediately study the Spring framework. Is this true? do I not need to learn servlets and JSPs to learn hibernate or Spring? All of their answers confused me and now I am completely lost what to learn or study. I feel that if I skipped learning JSP and servlets I would missed a lot of important concepts that will surely help me in the future. So the question, do I need to have foundation/know servlets and JSP to learn spring or hibernate or any other java web frameworks.?

• Web Service - SOAP

  - by seth

  My experience with web services is slim and I'm trying to understand this a little bit more. I have done for instance a web service using visual studio. In order to use it, I add a web service reference in my projects and this creates a proxy and the use is pretty simple. Does this use SOAP? I ask this because i will be now facing a web service that i must communicate using SOAP with attachements and i'm trying to understand the concept behind this and the difference to what i have done so far. Will the proxy still be viable or do i need to create the XML by hand and post it to the web service? This concepts still confuse and so any help is appreciated. EDIT: I'm not developing the service, i will be just using it.

• What's a good, quick algorithms refresh?

  - by Casey Patton

  I have programming interviews coming up in a couple weeks. I took an algorithms class a while ago but likely forgot some key concepts. I'm looking for something like a very short book (< 100 pages) on algorithms to get back up to speed. Sorting algorithms, data structures, and any other essentials should be included. It doesn't have to be a book...just looking for a great way to get caught up in about a week. What's the best tool for a quick algorithms intro or refresher?

• Reviewing Orace ADF Enterprise Application Development Made Simple Book

  - by Grant Ronald

  Although I was a technical reviewer of Oracle ADF Enterprise Application Development-Made Simple (by Sten Vesterli) it is nice to get the finished article in your hands as a real tangible book. Personally, on a sun lounger with a Dan Brown book I can read 300 pages a day, but technical books are a different beast and I find it hard to get through them with the same vigour.  However, I'm up to chapter 7 in Sten's book and so far it's holding my interest.  He writes in an almost conversational tone and I really like the comparisons to "real world" concepts - like page templates being like gingerbread cookie cutters.  Personally I like to be able to compare or size up a new concept against something I already know. I'll post a full review next week but the good news is 212 pages in and I'm still reading!

• Why is concept art not signed by the author?

  - by Gerald

  I am a starting concept artist who would like to enter the gaming industry. I noticed that some AAA titles show their concept art with no artists signature (only a reference to game the game, such as for Star Wars The Old Republic: 2013 ALL RIGHTS RESERVED BioWare, LucasArts). I asked myself a question, what possible harm could my autograph cause on the public concept art if I am not a well known concept artist such as Adam Adamowicz (who did concepts for Skyrim). Why would a prospective boss tells me not to leave my "finger print" on the picture despite, the fact that I am a very talented artist?

• Physics/Graphics Components

  - by Brett Powell

  I have spent the last 48 hours reading up on Object Component systems, and feel I am ready enough to start implementing it. I got the base Object and Component classes created, but now that I need to start creating the actual components I am a bit confused. When I think of them in terms of HealthComponent or something that would basically just be a property, it makes perfect sense. When it is something more general as a Physics/Graphics component, I get a bit confused. My Object class looks like this so far (If you notice any changes I should make please let me know, still new to this)... typedef unsigned int ID; class GameObject { public: GameObject(ID id, Ogre::String name = ""); ~GameObject(); ID &getID(); Ogre::String &getName(); virtual void update() = 0; // Component Functions void addComponent(Component *component); void removeComponent(Ogre::String familyName); template<typename T> T* getComponent(Ogre::String familyName) { return dynamic_cast<T*>(m_components[familyName]); } protected: // Properties ID m_ID; Ogre::String m_Name; float m_flVelocity; Ogre::Vector3 m_vecPosition; // Components std::map<std::string,Component*> m_components; std::map<std::string,Component*>::iterator m_componentItr; }; Now the problem I am running into is what would the general population put into Components such as Physics/Graphics? For Ogre (my rendering engine) the visible Objects will consist of multiple Ogre::SceneNode (possibly multiple) to attach it to the scene, Ogre::Entity (possibly multiple) to show the visible meshes, and so on. Would it be best to just add multiple GraphicComponent's to the Object and let each GraphicComponent handle one SceneNode/Entity or is the idea to have one of each Component needed? For Physics I am even more confused. I suppose maybe creating a RigidBody and keeping track of mass/interia/etc. would make sense. But I am having trouble thinking of how to actually putting specifics into a Component. Once I get a couple of these "Required" components done, I think it will make a lot more sense. As of right now though I am still a bit stumped.

• Learning Asynchronous programming

  - by xenoterracide

  Asynchronous non-blocking event driven programming seems to be all the rage. I have a basic conceptual understanding of what this all means. However what I'm not sure is when and where my code can benefit from being asynchronous, or how to make blocking IO, non-blocking. I'm sure that I can simply use a library to do this, but I'm more interested in more in depth concepts, and the various ways to implement it myself. Are there any comprehensive/definitive books, or other resources on this subject (like GoF for Design Patterns, or K&R for C, tldp for things like bash)? (Note: I'm not sure if this is actually functionally an identical question to my question on Learning event driven programming)

• Absolute statements in IT that are wrong

  - by Dan McGrath

  I was recently in a discussion about the absolute statement "It costs more in programming time to optimise software than it costs to throw hardware at a problem". The general thought (of which I agree with) is that as an absolute statement this is wrong. There are too many variables to ever generalise in such a way. What other statements do you hear about software/programming that simply do not work as an absolute and why?

• Do most programmers copy and paste code?

  - by John MacIntyre

  I learned very early on that cutting & pasting somebody else's code takes longer in the long run that writing it yourself. In my opinion unless you really understand it, cut & paste code will probably have issues which will be a nightmare to resolve. Don't get me wrong, I mean finding other peoples code and learning from it is essential, but we don't just paste it into our app. We rewrite the concepts into our app. But I'm constantly hearing about people who cut & paste, and they talk about it like it's common practice. I also see comments by others which indicate it's common practice. So, do most programmers cut & paste code?

• Online training modules / programs for best software engineering practices?

  - by Steve

  We're taking over a team in a foreign country and the programming standards there aren't up to par with US standards. Folks there lack the formal training and basic understanding of computing concepts of databases, how computers work, what good software engineering practices are. Short of sending these ppl to college again, are there good online courses available that we can enroll them into so that they can upgrade their skills? I am specifically looking for online training courses, but recommendations for books are also welcome. This is language-agnostic.

• What are graphs in laymen's terms

  - by Justin984

  What are graphs, in computer science, and what are they used for? In laymen's terms preferably. I have read the definition on Wikipedia: In computer science, a graph is an abstract data type that is meant to implement the graph and hypergraph concepts from mathematics. A graph data structure consists of a finite (and possibly mutable) set of ordered pairs, called edges or arcs, of certain entities called nodes or vertices. As in mathematics, an edge (x,y) is said to point or go from x to y. The nodes may be part of the graph structure, or may be external entities represented by integer indices or references. but I'm looking for a less formal, easier to understand definition.

• How can I quantify the amount of technical debt that exists in a project?

  - by Erik Dietrich

  Does anyone know if there is some kind of tool to put a number on technical debt of a code base, as a kind of code metric? If not, is anyone aware of an algorithm or set of heuristics for it? If neither of those things exists so far, I'd be interested in ideas for how to get started with such a thing. That is, how can I quantify the technical debt incurred by a method, a class, a namespace, an assembly, etc. I'm most interested in analyzing and assessing a C# code base, but please feel free to chime in for other languages as well, particularly if the concepts are language transcendent.
