• TechEd 2014 Day 1

  - by John Paul Cook

  Today at TechEd 2014, many people had questions about the in-memory database features in SQL Server 2014. A common question is how an in-memory database is different from having a database on a SQL Server with an amount of ram far greater than the size of the database. In-memory or memory optimized tables have different data structures and are accessed differently using a latch free and lock free approach that greatly improves performance. This provides part of the performance improvement. The rest...(read more)

• Inspiring People

  - by barrem23

  So I work with a few people that I feel are intelligent but don't seem to be working out well. After working with them for a while I have seen the flashes of brilliance but mostly I see a reliance on others. What I mean by this is that most times it seems like at the first moment of trouble they go ask for help. Now personally I am all for helping and spend a significant portion of time helping others with whatever they need, but after helping others for so long I have noticed a disturbing trend. These people seem terrified that they might make a mistake and because of this they don't try. So my question is how can I motivate someone who is afraid of making a mistake? In my career I have always learned the most by making mistakes and learning from them. Personally I feel that if I hadn't learned so much I would never have made it as far as I have. So how can I get them to discover that they have the ability to figure it out themselves and that if they make a mistake and learn from it they will be better off. I feel that if I can discover some way to properly motivate them that we all will be better off.

• Service Catalogs for Database as a Service

  - by B R Clouse

  At the end of last month, I had the opportunity to present a speaking session at Oracle OpenWorld: Database as a Service: Creating a Database Cloud Service Catalog.  The session was well-attended which would have surprised me several months ago when I started researching this topic.  At that time, I thought of service catalogs as something trivial which could be explained in a few simple slides.  But while looking at all the different options and approaches available, I came to learn that designing a succinct and effective catalog is not a trivial task, and mistakes can lead to confusion and unintended side effects.  And when the room filled up, my new point of view was confirmed. In case you missed the session, or were able to attend but would like more details, I've posted a white paper that covers the topics from the session, and more.  We start with an overview of the components of a service catalog: And then look at several customer case studies of service catalogs for DBaaS.  Synthesizing those examples, we summarize the main options for defining the service categories and their levels.  We end with a template for defining Bronze | Silver | Gold service tiers for Oracle Database Services. The paper is now available here - watch for updates as we work to expand some sections and incorporate readers' feedback (hint - that includes your feedback). Visit our OTN page for additional Database Cloud collateral.

• What does it mean to be agile?

  - by JD01

  We have a project that everyone says we will be doing in a agile way but I doubt we have clearly understood what agile is. In previous projects we had planning meetings, then defined the product back log and allocated the work to developers in 2 to 3 week sprints. Every morning we had scrum meetings (which seemed to go on for 1/2 an hour each time) and each developer got on with it after that. Hardly anyone wrote any tests until at the end of sprint and work that was not completed was added on to the next sprint. Developers hardly spoke to each other and there was no TDD involved in development. In fact most developers had a spec at the start and just got on with it for the 2 or 3 weeks the sprint was arranged for. There was hardly any communication with the client/stake holder. QA got involved usually a few months later and by then we found missing requirements which further increased the amount of work we had to do. Clearly there was no feedback loop. So my question is, where did we go wrong and how can I prevent the team from making the same mistakes.

• check two conditions in two different columns in excel and count the matches

  - by user1727103

  I've trying to create a Error Log to help me analyse my mistakes. So for simplicity, lets assume I have two columns "Type of Question" - with values SC,RC,CR and another column that indicates whether I got this question "right/wrong".Let's assume this is my table: Question No. | Right/Wrong | Question Type | Right | SC | Right | RC | Wrong | SC | Wrong | CR | Right | RC (Pardon my formatting skills). And I want an output table like this Type of Question | Right | Wrong | Total SC | 1 | 1 | 2 RC | 2 | 0 | 2 CR | 0 | 1 | 1 So basically what I want to do is check Column3 for SC using =COUNTIF(C1:C5,"SC"), and return the total number of SC questions, and then outta the SC , I need to find out which are Right.If I know the right and the total I can get the wrong. I have never written a macro so a formula based answer would suffice.

• How to synchronize the ball in a network pong game?

  - by Thaars

  I’m developing a multiplayer network pong game, my first game ever. The current state is, I’ve running the physic engine with the same configurations on the server and the clients. The own paddle movement is predicted and get just confirmed by the authoritative server. Is a difference detected between them, I correct the position at the client by interpolation. The opponent paddle is also interpolated 200ms to 100ms in the past, because the server is broadcasting snapshots every 100ms to each client. So far it works very well, but now I have to simulate the ball and have a problem to understanding the procedure. I’ve read Valve’s (and many other) articles about fast-paced multiplayer several times and understood their approach. Maybe I can compare my ball with their bullets, but their advantage is, the bullets are not visible. When I have to display the ball, and see my paddle in the present, the opponent in the past and the server is somewhere between it, how can I synchronize the ball over all instances and ensure, that it got ever hit by the paddle even if the paddle is fast moving? Currently my ball’s position is simply set by a server update, so it can happen, that the ball bounces back, even if the paddle is some pixel away (because of a delayed server position). Until now I’ve got no synced clock over all instances. I’m sending a client step index with each update to the server. If the server did his job, he sends the snapshot with the last step index of each client back to the clients. Now I’m looking for the stored position at the returned step index and compare them. Do I need a common clock to sync the ball? EDIT: I've tried to sync a common clock for the server and all clients with a timestamp. But I think it's better to use an own stepping instead of a timestamp (so I don't need to calculate with the ping and so on - and the timestamp will never be exact). The physics are running 60 times per second and now I use this for keeping them synchronized. Is that a good way? When the ball gets calculated by each client, the angle after bouncing can differ because of the different position of the paddles (the opponent is 200ms in the past). When the server is sending his ball position, velocity and angle (because he knows the position of each paddle and is authoritative), the ball could be in a very different position because of the different angles after bouncing (because the clients receive the server data after 100ms). How is it possible to interpolate such a huge difference? I posted this question some days ago at stackoverflow, but got no answer yet. Maybe this is the better place for this question.

• Where in the filesystem should I store shared data?

  - by misterben

  Where in the unix filesystem is the conventional location to save non-user specific data, for example data shared via nfs or ftp, or backups? I could obviously create and use any arbitrary folder (such as /home/shared, /data or /var/data), but I'm really wondering if there are any "best" or "common" practice guidelines. The Filesystem Hierarchy Standard doesn't specify a location for shared data. For backups, I tend to use /var/backups, but as several cronjobs write to it should it really be left for their use?

• REST API at backend and MVC Javascript framework at client side

  - by Prashere

  I am building an online social network. I have finished writing RESTful API service using Django. This will return only JSON response (No HTML will be generated from server side) so that this JSON response can be used to build native smartphone apps. API service being common to all clients. My question is, since there is no HTML response from server side, can the MV* Javascript Frameworks like Angular / Backbone / Ember take care of complete Front-end, right from generating HTML page with CSS?

• Why would you use data structures (ie Binary Trees, Linked Lists) in your jobs/side projects? [closed]

  - by Chris2021

  It seems to me that, for everyday use, more primitive data structures like arrays get the job done just as well as a binary tree would. My question is how common is to use these structures when writing code for projects at work or projects that you pursue in your free time? I understand the better insertion time/deletion time/sorting time for certain structures but would that really matter that much if you were working with a relatively small amount of data?

• Is there a better strategy than relying on the compiler to catch errors?

  - by koan

  I've been programming in C and C++ for some time, although I would say I'm far from being an expert. For some time, I've been using various strategies to develop my code such as unit tests, test driven design, code reviews and so on. When I wrote my first programs in BASIC, I typed in long blocks before finding they would not run and they were a nightmare to debug. So I learned to write a small bit and then test it. These days, I often find myself repeatedly writing a small bit of code then using the compiler to find all the mistakes. That's OK if it picks up a typo but when you start adjusting the parameters types etc just to make it compile you can screw up the design. It also seems that the compiler is creeping into the design process when it should only be used for checking syntax. There's a danger here of over reliance on the compiler to make my programs better. Are there better strategies than this? I vaguely remember some time ago an article on a company developing a type of C compiler where an extra header file also specified the prototypes. The idea was that inconsistencies in the API definition would be easier to catch if you had to define it twice in different ways.
