SQL Saturday #274 Slovenia
- by Dejan Sarka
Yes, here it is SQL Saturday #274 is coming to Slovenia (#sqlsatSlovenia). The event will take place on Saturday, December 21st, at company pixi* labs, Informacijske tehnologije, d.o.o. Poslovna cona A 2 SI-4208 Šencur This company generously offered to host the event. We, the whole Slovenian SQL Server community, are very grateful for this. At this time, a call for speakers went out, and we are already getting the first proposals. We are especially happy that we will get possibility to show the foreign speakers how beautiful Slovenia and especially the capital Ljubljana is in December. Expect a lot of partying right on the streets, no matter of weather. Be prepared, we have slightly weird customs when it comes to drinks. For example, our regular special discount offer is not three drinks for the price of two; it is six drinks for the price of five. If you are a speaker or want to become one, consider sending a proposal. Since most of the sessions will be held in English and you don’t want to speak, consider coming as a visitor as well. Or maybe you would be interested to become a sponsor. Although we are targeting a low budgeted event, any kind of sponsorship is very welcome. Please feel free to contact the organizers if you are interested to become a sponsor: Matija Lah – [email protected], Mladen Prajdic - [email protected], or Dejan Sarka - [email protected]. Looking forward to see you all!Read the article

How to work with scenes in a 2D game
- by Anearion
I'm a java/android programmer, but I don't have any experience in game programming, I'm already reading proper books, like "Pro Android Games", but my concerns are more about the ideas behind game programming than the techniques themselves. I'm working on a 2D game, something like Cluedo to let you understand the genre. I would like to know how should I act with the "scenes", for example, a room with a desk, TV, windows and a lamp. I need to make some items tappable and others not. Is it common to use one image (invisible to the user) with every different item a different color, then call the getColor() method on the image? Or use one image as background, and separate images for all the items? If the latter, how can I set the positioning? and should I use imageView or imageButton? I'm sorry if those are really low quality questions, but as "outsider" ( I'm 23 and still finishing my university ) it's pretty hard learn alone.Read the article

Solo .NET Programmer moving to a team
- by 219558af-62fa-411d-b24c-d08dab
I've been a solo .NET programmer for a small startup for the last 8 years. I've put together some pretty decent software, and I always strived to better myself and conform to best practices, including source control (SVN/TFS). I worked very closely with a team of engineers of other disciplines, but when it came down to the software I was the only one programming. I love the craft of programming and love learning new things to sharpen my tools. In 2 weeks I will be starting a new job in a team of 20 .NET developers. My position will be mid-level, and I will be working under some programmers with incredibly impressive backgrounds. Again, the team aspect of development will be new to me, so I'm looking for some general "new guy" tips that will help me be as effective and easy to get along with as possible from the get-go. Anything goes, including high level tips, and small day-to-day things about communication. Thanks for any and all input!Read the article

How to get feedback on mobile application
- by Jason Crosby
I am relatively new to programming. I have been programming with Java and Android for about 2 years now and just recently released my first app to the Google Play app store. I have passed the word on to everyone I know and posted a few times on Facebook about it. But I am not really seeing anyone install them. I love to code I'm not looking to have the next big time app, but it would be nice to get some installs and feedback/ratings so I can get an idea of how well its doing and if there are any fixes or improvements I can make. I thought about doing an AdMob campaign a couple times here and there at about $10 to $20 per day. But I'm not sure if that will generate any kind of worthwhile feedback. What other things could I be doing in order to get some feedback on my application? Thanks in advance for your help and suggestions.Read the article

MS in Computer Science after BE in electronics
- by Abhinav
I am doing my 3rd year Bachelors in Electronics and Electrical Communication but from the first year I have been interested in Computer Science. But at that time it was just my hobby. But in second year when I joined robotics my love for computer science rose. I with my team came in top three in 2 National Competition (Technical fests of different IITs) where we used Image Processing, Hardware interfacing etc. But then I realised that Computer Science is not just about coding. I took many lectures from online free schools like Udacity, Coursera in subjects related to Artificial Intelligence, Building a Search Engine, Design and Analysis of Algorithm, Programming a Robotic Car, Programming Languages, Machine Learning, Software Engineering as a Service, WebApps Engineering, Compilers, Applied Crypotography etc. I also did some courses in Core and Advanced Java in my second year from training institute. I will also be taking course in Statistics, Databases, Discrete Mathematics from 25th June. Now I realized how vast is the field of Computer Science and how efficient you become on deciding algorithms and classifying problems into different subfields which have been thoroughly researched so you don't always do brute force thing or naive programming. Now this field has become kind of passion for me. Adding to the fact I am also doing my 6 months internship in software field in Texas Instruments where I am working on Automation and Algorithms. I also have some 5-6 good college level projects in Softwares and Robotics. I also like Electronics but only some fields like Operating System(this subject was there in Electronics also), Micro Processor, Digital, Computer Architecture, DSPs etc. I really want to pursue MS in some field of Computer Science. I am giving GRE in October/November. Till now I have good CG of around 9.4/10 and my 1 year in college is still left. Do I have any chance that some good University in US will consider me for MS in field related to computer science or Robotics. Also Can you suggest somethings that I can do during this 1 year to increase my chances for MS or should I apply for EECS(Electrical Engineering and Computer Science) and then I can shift more towards Computer Science as my major option. My main aim is to do Phd after Ms in CS if I am able to do that somehow. I know that I have to put much extra effort to understand things in MS than CS undergraduates but I will do that with my full dedication, also when I communicate with my college CS students or during my internship period I didn't feel that I am missing very much stuff that they know and was very comfortable during my internship with software employees.Read the article

Restore access to Cisco Connect after changing router settings
- by StasM
I have recently bought Cisco Valet Plus (M20) wireless router (which I recognize now was a mistake, but nevermind). It has two setup options - Cisco Connect software and web-based setup. Cisco Connect software allows changing very small set of settings, web-based setup allows access to almost all settings, except settings for guest network. The problem is that when I use web-based setup, Cisco Connect after some changes refuses to talk to the router, so I can't change guest settings anymore (since web interface doesn't allow to change them). It must be because of some config parameter not matching or some password set wrong - but I don't know where Cisco Connect stores them. So, does anybody have any idea how to make Cisco Connect talk to the router again once I changed the settings through the web interface?Read the article

Reusing Web Forms across BPM Roles
- by Mona Rakibe
Recently Varsha(another BPM Product Manager) approached me with a requirement where she wanted to reuse same Web Form for different task activity.We both knew this is easily achievable.The human task outcomes can differ to distinguish the submission based on roles.Her requirement was slightly more than this, she wanted to hide some data based on the logged in user. If you have worked on Web Form rules, dynamically showing and hiding data is common requirement and easily achievable using Form Rules. In this case the challenge was accessing BPM role inside the Web Form. Although, will be addressing this requirement in future release she wanted a immediate solution(Aha, after all customers are not the only one's who can not wait). Thankfully we managed to come-up with a solution and I hope this will be helpful to larger audience. Solution has 3 steps : Step 1: We added a hidden attribute in our form (Role). The purpose of this attribute is just to store the current logged in user's role and we pass the value during data association. Step 2 : In your data association step, pass the role value based on the Swimlane Step 3 : Now use this hidden attribute value in your Web Form rule for dynamic behavior Detailed steps and sample can be downloaded from Java.net.Read the article

Generated 3d tree meshes
- by Jari Komppa
I did not find a question on these lines yet, correct me if I'm wrong. Trees (and fauna in general) are common in games. Due to their nature, they are a good candidate for procedural generation. There's SpeedTree, of course, if you can afford it; as far as I can tell, it doesn't provide the possibility of generating your tree meshes at runtime. Then there's SnappyTree, an online webgl based tree generator based on the proctree.js which is some ~500 lines of javascript. One could use either of above (or some other tree generator I haven't stumbled upon) to create a few dozen tree meshes beforehand - or model them from scratch in a 3d modeller - and then randomly mirror/scale them for a few more variants.. But I'd rather have a free, linkable tree mesh generator. Possible solutions: Port proctree.js to c++ and deal with the open source license (doesn't seem to be gpl, so could be doable; the author may also be willing to co-operate to make the license even more free). Roll my own based on L-systems. Don't bother, just use offline generated trees. Use some other method I haven't found yet.Read the article

Business person turned into coder? How and why? Inspire the non-technical.
- by huisjames
I graduated with a Business degree. Two years later, I finally realized the power of programming - the power to "invent." I wish I realized this in high school. Nevertheless, I tried to self-teach C# but found it difficult. Then I pivoted to learn PHP two months ago and I have been able to build things I thought was beyond my abilities. Has anyone had the same experience? Or self-taught programming? What lessons did you learn?Read the article

SDL mouse wheel not picking up
- by Chris
Running Ubuntu 11.04, SDL 1.2 trying to pickup mouse wheel up/down movement with this (stripped down) code: int main( int argc, char **argv ) { SDL_MouseButtonEvent *mousebutton = NULL; while ( !done ) { if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_LEFT) yrot += 0.75f; else if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_RIGHT) yrot -= 0.75f; else if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_WHEELUP){ xrot += 0.75f; }else if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_WHEELDOWN){ xrot -= 0.75f; } while ( SDL_PollEvent( &event ) ) { switch( event.type ) { case SDL_MOUSEBUTTONDOWN: mousebutton = &event.button; break; case SDL_MOUSEBUTTONUP: mousebutton = NULL; break; default: break; } } } return 0; } strange thing is, scrolling with the mouse button does nothing, but if I hold down a mouse button or two and then move the mouse it hits the SDL_BUTTON_WHEEL code occasionally. This honestly reeks of a pointer issue, which would make sense since I've been spoiled with C# for the past couple years, but I am just not seeing it. How do i correctly find mouse scroll events in SDL?Read the article

Best book for developer who needs to learn software fundamentals
- by tharrison
I have recently inherited a team of developers, none of whom really have any programming experience. Some are really bright, and are learning on their own. I am looking for one or two books that are practical but show the core practices of professional development: Structure, OO, naming, DRY, why elegance matters, etc. When I was learning, I loved Code Complete, and Programming Pearls, but they are dated now. Any recommendations for good books that could be used in tandem with a language specific book to help understand? Thanks in advance!Read the article

Hi, company where I applied for a job requires a very detailed CV mainly of programming languages, frameworks, technology. My CV have 3 pages but for this company is not enough detailed. ;) What structure have your CV in programming languages, frameworks, technology, third-party libraries? Any sample of good structured CV. (as pdf file) Of course I had used the google but I found a dozen same old things. I would like have someting orignal and fresh. Any inspiration? I do not know what to write for example C #. C# OOP, delagate, event, generic, LINQ other WPF control, data template, converter, style, triggers..? Prims, Caliburn, MEF ? Also which skills from OS, IDE, util is suitably to have in CV. I would’t have a 10 pages CV or have bad and immense structure of CV. Sory for my englishRead the article

Career Development: What should I learn next after Python? and Why? [closed]
- by Josh
Hi all I'm currently learning Python. I want to know what should I learn next out of these programming langauages: PHP Actionscript 3 Objective-C (iPhone applications) I work in the Multimedia industry and have decided to learn Python as a first programming language seriously because I would like to learn the basics of programming, to mainly write scripts at work that Automate task (eg. Edit multiple XML files quickly) At work we have a senior developer who knows Actionscript and PHP very well (although knows PHP better). We also have been developing iPhone applications for 2 weeks, Our senior developer could learn it although we have lots of work currently with PHP and Actionscript 3 type work and haven't had time or reason to pick up iOS development. Here are the reasons I want to learn each language, But I cannot decide what I'll learn next: PHP: I want to learn PHP because it will help with Web Development. PHP is very wanted by employers. Senior developer at work writes everything in it web sites, CMS etc. (including XML checks and scripts), I will learn a lot from him (once I learn the basics). However, I don't want to learn Web because you have to deal with lots of cross-browser problems. Actionscript 3: At work we are looking to put on another developer to help with online activities and very small games (using Actionscript 3.0 and Flash CS5) for (eg. First Aid Activities etc) I would like to do things that have a element of design as I'm better at Photoshop then developing. I want to be creative, I like to interact with users in a fun way. Objective-C (iPhone applications): We are a all mac office, we may get more iPhone, iPad application work(jobs) that need to be created. Work has found it nearly impossible to find good iPhone developers. I like apple products (Macs and iPhones), I would like to make my own games, applications in my spare time(if I knew how). Should I learn Actionscript first because it would be easier to learn then Objective-C? Should I learn PHP because it is very widely used? Should I learn Objective-C because it is really wanted by employers now?Read the article

Taming Hopping Windows
- by Roman Schindlauer
At first glance, hopping windows seem fairly innocuous and obvious. They organize events into windows with a simple periodic definition: the windows have some duration d (e.g. a window covers 5 second time intervals), an interval or period p (e.g. a new window starts every 2 seconds) and an alignment a (e.g. one of those windows starts at 12:00 PM on March 15, 2012 UTC). var wins = xs .HoppingWindow(TimeSpan.FromSeconds(5), TimeSpan.FromSeconds(2), new DateTime(2012, 3, 15, 12, 0, 0, DateTimeKind.Utc)); Logically, there is a window with start time a + np and end time a + np + d for every integer n. That’s a lot of windows. So why doesn’t the following query (always) blow up? var query = wins.Select(win => win.Count()); A few users have asked why StreamInsight doesn’t produce output for empty windows. Primarily it’s because there is an infinite number of empty windows! (Actually, StreamInsight uses DateTimeOffset.MaxValue to approximate “the end of time” and DateTimeOffset.MinValue to approximate “the beginning of time”, so the number of windows is lower in practice.) That was the good news. Now the bad news. Events also have duration. Consider the following simple input: var xs = this.Application .DefineEnumerable(() => new[] { EdgeEvent.CreateStart(DateTimeOffset.UtcNow, 0) }) .ToStreamable(AdvanceTimeSettings.IncreasingStartTime); Because the event has no explicit end edge, it lasts until the end of time. So there are lots of non-empty windows if we apply a hopping window to that single event! For this reason, we need to be careful with hopping window queries in StreamInsight. Or we can switch to a custom implementation of hopping windows that doesn’t suffer from this shortcoming. The alternate window implementation produces output only when the input changes. We start by breaking up the timeline into non-overlapping intervals assigned to each window. In figure 1, six hopping windows (“Windows”) are assigned to six intervals (“Assignments”) in the timeline. Next we take input events (“Events”) and alter their lifetimes (“Altered Events”) so that they cover the intervals of the windows they intersect. In figure 1, you can see that the first event e1 intersects windows w1 and w2 so it is adjusted to cover assignments a1 and a2. Finally, we can use snapshot windows (“Snapshots”) to produce output for the hopping windows. Notice however that instead of having six windows generating output, we have only four. The first and second snapshots correspond to the first and second hopping windows. The remaining snapshots however cover two hopping windows each! While in this example we saved only two events, the savings can be more significant when the ratio of event duration to window duration is higher. Figure 1: Timeline The implementation of this strategy is straightforward. We need to set the start times of events to the start time of the interval assigned to the earliest window including the start time. Similarly, we need to modify the end times of events to the end time of the interval assigned to the latest window including the end time. The following snap-to-boundary function that rounds a timestamp value t down to the nearest value t' <= t such that t' is a + np for some integer n will be useful. For convenience, we will represent both DateTime and TimeSpan values using long ticks: static long SnapToBoundary(long t, long a, long p) { return t - ((t - a) % p) - (t > a ? 0L : p); } How do we find the earliest window including the start time for an event? It’s the window following the last window that does not include the start time assuming that there are no gaps in the windows (i.e. duration < interval), and limitation of this solution. To find the end time of that antecedent window, we need to know the alignment of window ends: long e = a + (d % p); Using the window end alignment, we are finally ready to describe the start time selector: static long AdjustStartTime(long t, long e, long p) { return SnapToBoundary(t, e, p) + p; } To find the latest window including the end time for an event, we look for the last window start time (non-inclusive): public static long AdjustEndTime(long t, long a, long d, long p) { return SnapToBoundary(t - 1, a, p) + p + d; } Bringing it together, we can define the translation from events to ‘altered events’ as in Figure 1: public static IQStreamable<T> SnapToWindowIntervals<T>(IQStreamable<T> source, TimeSpan duration, TimeSpan interval, DateTime alignment) { if (source == null) throw new ArgumentNullException("source"); // reason about DateTime and TimeSpan in ticks long d = Math.Min(DateTime.MaxValue.Ticks, duration.Ticks); long p = Math.Min(DateTime.MaxValue.Ticks, Math.Abs(interval.Ticks)); // set alignment to earliest possible window var a = alignment.ToUniversalTime().Ticks % p; // verify constraints of this solution if (d <= 0L) { throw new ArgumentOutOfRangeException("duration"); } if (p == 0L || p > d) { throw new ArgumentOutOfRangeException("interval"); } // find the alignment of window ends long e = a + (d % p); return source.AlterEventLifetime( evt => ToDateTime(AdjustStartTime(evt.StartTime.ToUniversalTime().Ticks, e, p)), evt => ToDateTime(AdjustEndTime(evt.EndTime.ToUniversalTime().Ticks, a, d, p)) - ToDateTime(AdjustStartTime(evt.StartTime.ToUniversalTime().Ticks, e, p))); } public static DateTime ToDateTime(long ticks) { // just snap to min or max value rather than under/overflowing return ticks < DateTime.MinValue.Ticks ? new DateTime(DateTime.MinValue.Ticks, DateTimeKind.Utc) : ticks > DateTime.MaxValue.Ticks ? new DateTime(DateTime.MaxValue.Ticks, DateTimeKind.Utc) : new DateTime(ticks, DateTimeKind.Utc); } Finally, we can describe our custom hopping window operator: public static IQWindowedStreamable<T> HoppingWindow2<T>( IQStreamable<T> source, TimeSpan duration, TimeSpan interval, DateTime alignment) { if (source == null) { throw new ArgumentNullException("source"); } return SnapToWindowIntervals(source, duration, interval, alignment).SnapshotWindow(); } By switching from HoppingWindow to HoppingWindow2 in the following example, the query returns quickly rather than gobbling resources and ultimately failing! public void Main() { var start = new DateTimeOffset(new DateTime(2012, 6, 28), TimeSpan.Zero); var duration = TimeSpan.FromSeconds(5); var interval = TimeSpan.FromSeconds(2); var alignment = new DateTime(2012, 3, 15, 12, 0, 0, DateTimeKind.Utc); var events = this.Application.DefineEnumerable(() => new[] { EdgeEvent.CreateStart(start.AddSeconds(0), "e0"), EdgeEvent.CreateStart(start.AddSeconds(1), "e1"), EdgeEvent.CreateEnd(start.AddSeconds(1), start.AddSeconds(2), "e1"), EdgeEvent.CreateStart(start.AddSeconds(3), "e2"), EdgeEvent.CreateStart(start.AddSeconds(9), "e3"), EdgeEvent.CreateEnd(start.AddSeconds(3), start.AddSeconds(10), "e2"), EdgeEvent.CreateEnd(start.AddSeconds(9), start.AddSeconds(10), "e3"), }).ToStreamable(AdvanceTimeSettings.IncreasingStartTime); var adjustedEvents = SnapToWindowIntervals(events, duration, interval, alignment); var query = from win in HoppingWindow2(events, duration, interval, alignment) select win.Count(); DisplayResults(adjustedEvents, "Adjusted Events"); DisplayResults(query, "Query"); } As you can see, instead of producing a massive number of windows for the open start edge e0, a single window is emitted from 12:00:15 AM until the end of time: Adjusted Events StartTime EndTime Payload 6/28/2012 12:00:01 AM 12/31/9999 11:59:59 PM e0 6/28/2012 12:00:03 AM 6/28/2012 12:00:07 AM e1 6/28/2012 12:00:05 AM 6/28/2012 12:00:15 AM e2 6/28/2012 12:00:11 AM 6/28/2012 12:00:15 AM e3 Query StartTime EndTime Payload 6/28/2012 12:00:01 AM 6/28/2012 12:00:03 AM 1 6/28/2012 12:00:03 AM 6/28/2012 12:00:05 AM 2 6/28/2012 12:00:05 AM 6/28/2012 12:00:07 AM 3 6/28/2012 12:00:07 AM 6/28/2012 12:00:11 AM 2 6/28/2012 12:00:11 AM 6/28/2012 12:00:15 AM 3 6/28/2012 12:00:15 AM 12/31/9999 11:59:59 PM 1 Regards, The StreamInsight TeamRead the article
