  • How to manage product backlog/user stories

    - by Andrew Stephens
    We're about to start a new project using Agile (using TFS), and I have a couple of "good practice" questions regarding the product backlog:- When we first start adding users stories, is it a good idea to put them in (say) a "Backlog" iteration, or just leave their iteration blank? Obviously when the time comes to start work on a US it would be moved into the appropriate iteration backlog. When breaking an epic down into smaller USs, would I simply close the original epic, as it's no longer required? Or should I create the new USs as children of the epic? (it's then someone's responsibility to close the epic once all child USs have been completed). Lastly, should the product backlog list all USs regardless of status, or only those that have not been started (i.e in my proposed "Backlog" iteration)? I realise these questions aren't life-or-death, but it would be nice to know how other people manage their product backlogs so we can organise things properly from the start.

  • The Island of Lost Apple Products

    - by Jason Fitzpatrick
    While Apple has has a mountain of commercial successes, every once in awhile the crew in Cupertino strikes out. Here are some of the less successful and prematurely retired Apple products from the last two decades. Courtesy of Wired, we find nine of the least favorably received products in the Apple portfolio. Pictured here, the QuickTake Camera: Life Span: 1994 – 1997 Back in 1994, Apple was actually at the forefront of digital photography. The QuickTake Camera’s photos (640 x 480 at 0.3 megapixels) were borderline unusable for anything other than your Geocities homepage. But technology has to start somewhere. Still, Apple killed the line after just three years. And while the iPhone and other smartphones have replaced most people’s digital cameras, Apple could have had a reaped the benefits of the digital point-and-shoot salad years. 6 Ways Windows 8 Is More Secure Than Windows 7 HTG Explains: Why It’s Good That Your Computer’s RAM Is Full 10 Awesome Improvements For Desktop Users in Windows 8

  • Some Insight on the Field of Knowledge Representations

    - by picmate
    I started following an MS in computer sciences after about two years of work for a software company. I worked primarily in data warehousing and business intelligence related software development during my previous occupation. There is a high chance for me to select a research in knowledge representations, ontologies and reasoning, as there are no other research available in any other interesting fields, such as pattern recognition and navigation. I developed an interest towards knowledge representation with what I learnt from the courses I am taking currently. But I do not have a deep understanding of it in terms of which areas such a field would have an impact in a real life scenario, and how it will help me when I am hunting for a job in the near future. Some thought about this would be greatly appreciated.

  • Different Not Automatically Implies Better

    - by Alois Kraus
    Originally posted on: http://geekswithblogs.net/akraus1/archive/2013/11/05/154556.aspxRecently I was digging deeper why some WCF hosted workflow application did consume quite a lot of memory although it did basically only load a xaml workflow. The first tool of choice is Process Explorer or even better Process Hacker (has more options and the best feature copy&paste does work). The three most important numbers of a process with regards to memory are Working Set, Private Working Set and Private Bytes. Working set is the currently consumed physical memory (parts can be shared between processes e.g. loaded dlls which are read only) Private Working Set is the physical memory needed by this process which is not shareable Private Bytes is the number of non shareable which is only visible in the current process (e.g. all new, malloc, VirtualAlloc calls do create private bytes) When you have a bigger workflow it can consume under 64 bit easily 500MB for a 1-2 MB xaml file. This does not look very scalable. Under 64 bit the issue is excessive private bytes consumption and not the managed heap. The picture is quite different for 32 bit which looks a bit strange but it seems that the hosted VB compiler is a lot less memory hungry under 32 bit. I did try to repro the issue with a medium sized xaml file (400KB) which does contain 1000 variables and 1000 if which can be represented by C# code like this: string Var1; string Var2; ... string Var1000; if (!String.IsNullOrEmpty(Var1) ) { Console.WriteLine(“Var1”); } if (!String.IsNullOrEmpty(Var2) ) { Console.WriteLine(“Var2”); } ....   Since WF is based on VB.NET expressions you are bound to the hosted VB.NET compiler which does result in (x64) 140 MB of private bytes which is ca. 140 KB for each if clause which is quite a lot if you think about the actually present functionality. But there is hope. .NET 4.5 does allow now C# expressions for WF which is a major step forward for all C# lovers. I did create some simple patcher to “cross compile” my xaml to C# expressions. Lets look at the result: C# Expressions VB Expressions x86 x86 On my home machine I have only 32 bit which gives you quite exactly half of the memory consumption under 64 bit. C# expressions are 10 times more memory hungry than VB.NET expressions! I wanted to do more with less memory but instead it did consume a magnitude more memory. That is surprising to say the least. The workflow does initialize in about the same time under x64 and x86 where the VB code does it in 2s whereas the C# version needs 18s. Also nearly ten times slower. That is a too high price to pay for any bigger sized xaml workflow to convert from VB.NET to C# expressions. If I do reduce the number of expressions to 500 then it does need 400MB which is about half of the memory. It seems that the cost per if does rise linear with the number of total expressions in a xaml workflow.  Expression Language Cost per IF Startup Time C# 1000 Ifs x64 1,5 MB 18s C# 500 Ifs x64 750 KB 9s VB 1000 Ifs x64 140 KB 2s VB 500 Ifs x64 70 KB 1s Now we can directly compare two MS implementations. It is clear that the VB.NET compiler uses the same underlying structure but it has much higher offset compared to the highly inefficient C# expression compiler. I have filed a connect bug here with a harsher wording about recent advances in memory consumption. The funniest thing is that one MS employee did give an Azure AppFabric demo around early 2011 which was so slow that he needed to investigate with xperf. He was after startup time and the call stacks with regards to VB.NET expression compilation were remarkably similar. In fact I only found this post by googling for parts of my call stacks. … “C# expressions will be coming soon to WF, and that will have different performance characteristics than VB” … What did he know Jan 2011 what I did no know until today? ;-). He knew that C# expression will come but that they will not be automatically have better footprint. It is about time to fix that. In its current state C# expressions are not usable for bigger workflows. That also explains the headline for today. You can cheat startup time by prestarting workflows so that the demo looks nice and snappy but it does hurt scalability a lot since you do need much more memory than necessary. I did find the stacks by enabling virtual allocation tracking within XPerf which is still the best tool out there. But first you need to look at your process to check where the memory is hiding: For the C# Expression compiler you do not need xperf. You can directly dump the managed heap and check with a profiler of your choice. But if the allocations are happening on the Private Data ( VirtualAlloc ) you can find it with xperf. There is a nice video on channel 9 explaining VirtualAlloc tracking it in greater detail. If your data allocations are on the Heap it does mean that the C/C++ runtime did create a heap for you where all malloc, new calls do allocate from it. You can enable heap tracing with xperf and full call stack support as well which is doable via xperf like it is shown also on channel 9. Or you can use WPRUI directly: To make “Heap Usage” it work you need to set for your executable the tracing flags (before you start it). For example devenv.exe HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\devenv.exe DWORD TracingFlags 1 Do not forget to disable it after you did complete profiling the process or it will impact the startup time quite a lot. You can with xperf attach directly to a running process and collect heap allocation information from a gone wild process. Very handy if you need to find out what a process was doing which has arrived in a funny state. “VirtualAlloc usage” does work without explicitly enabling stuff for a specific process and is always on machine wide. I had issues on my Windows 7 machines with the call stack collection and the latest Windows 8.1 Performance Toolkit. I was told that WPA from Windows 8.0 should work fine but I do not want to downgrade.

  • Visual Studio 2010: Fun with extensions

    - by BizTalk Visionary
    One of the powerful things that has come into Visual Studio over the last few years has been joy of extensions. With 2010 there seems to be even more!! Of course teaching old dogs like myself new tricks always takes time but interestingly enough some of the rules I learnt early in my working life over 30 years ago still hold true!! A derivation of one that was knocked into during my engineering apprenticeship and associated exams was RTFQ! Read the ‘flippin’ question. (I replaced the original ‘F’ with a more palatable version here!). Today I forgot that rule and didn’t RTFI (I being instructions) and spent a fruitless hour wondering why my Entity Framework POCO generator never appeared in the new project template list when I wanted to add it!! It was simple of course – I had only installed the Entity Framework POCO generator for web sites and not building a web project meant it would never appear!!! A quick look again I found the ‘other’ extension that supported my project type! So RTFI!!

  • How do I install the Intel Graphics driver in my system?

    - by John
    Can someone help me out and explain or point me in the right direction on how to check video drivers and see if my video card running okay? I had 10.04 installed on my Thinkpad r61 with Compiz Manager and life was great, until the machine took water damage. I bought an ASUS (X54H) since and am trying out 12.04, but the desktop just doesn't look right. I always struggled with video driver installation. There are no proprietary drivers available in the hardware manager. When I run lspci | grep VGA: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) I will greatly appreciate your help. I want to use Linux more, but like I said video drivers appear to be my biggest concern. I have also tried 12.04 on my desktop PC, but again failed to configure video card, so switched back to Windows 7.

  • How To Boot Your Android Phone or Tablet Into Safe Mode

    - by Chris Hoffman
    On your Windows PC, you can boot into safe mode to load Windows without any third-party software. You can do the same on Android with Android’s safe mode. In safe mode, Android won’t load any third-party applications. This allows you to troubleshoot your device – if you’re experiencing crashes, freezes, or battery life issues, you can boot into safe mode and see if the issues still happen there. From safe mode, you can uninstall misbehaving third-party apps. HTG Explains: Does Your Android Phone Need an Antivirus?

  • Simulating Smartphones on PC with Unity

    - by Cengiz Frostclaw
    I want to make a game that depends on the phone orientation (changing shoot direction with tilt), however I need to test this on PC. So is there any tool I can use to simulate the orientation of the phone with mouse or keyboard of my PC? Something like joysticks on the screen. Thanks for any help! Edit : Thanks to @jhocking for his suggestion of Unity Remote. I, however still can accept a solution with using only PC, since I'm afraid of shortening my phone's battery life, for some reason.

  • Don't Call it a Comeback

    - by Chris Haaker
    I received the email like most of you about Jeff and crew stepping down and selling the blog to another company. That it is a long time associate and friend of the team we have all grown to know and love, I feel much better about the move. Who cares, Chris, you haven't blogged religiously in ages! I know, and its a crime. Blame life, Twitter, my kids, laziness or whatever else you can think of. I always tell myself I am going to make a comeback - - "Don't call it a comeback - I been here for years." But after a few posts I seem to lose my steam. Its hard to explain, hell, I can't explain it. But we'll see what happens this time. Just don't call it a comeback.  2012 rMBP 15" Quad Core 2.33 GHz 16GB Memory 258GB SSDMarsEdit 3.5 (Please Microsoft Live Team - Make LiveWriter for OS X)

  • How can I share my python scripts with my less python-savvy business person partner?

    - by Alex
    I'm taking financial mathematics as an elective, and I'm working with real life finance industry worker type people. It's actually kind of fun. When I pulled out a macbook at one of our meetings, I had four lifelong windows users look at me like I had three heads. Anyway, I'm helping with design and simulation of our trading strategy, and I wrote a little thing using matplotlib to visualize historical stock data. However, these guys don't know how to use git, or install python, or deal with path-related package management things. I need to be able to send my scripts to them to use, and I need to do it with absolutely minimal effort on their part. I was thinking something on the lines of py2exe, but I'd like to hear some advice before I go ahead.

  • Ubuntu reports low battery capacity on my Dell Vostro

    - by Jeff
    I have a Dell Vostro 1500. Before I wiped Windows XP off my hard drive in 2009, I had a full ~7 hrs battery capacity. I installed Ubuntu 9, and the capacity immediately dropped to about 27% (and has since decreased to about 11%). I couldn't figure out what to do, so I've just lived with the 20-30 minute battery life ever since. I upgraded to Ubuntu 10, and the issue remained. I wiped my hard drive clean again and installed Ubuntu 11, and the issue still remains. I tried what they told me in the forum here, but it didn't do anything. Is it possible for a battery to suddenly lose most of its capacity?? Or is there a bug in the power management software?

  • How to disable Alert volume from the command line in Natty?

    - by Bryce
    There is an option in the Sound Preferences dialog, Sound Effects tab, to toggle Alert volume 'mute'. It works and suffices for my needs to disable the irritating system beep/bell. However, I reinstall systems a LOT for testing purposes and would like to set this setting in a shell script so it's off without having to fiddle with a GUI. But for the life of me I can't seem to find where this can be toggled via a command line tool. I've scanned through gconf-editor, pulseaudio's pacmd, grepped through /etc, even dug through the gnome-volume-control source code, but I am not seeing how this can be set. I gather that gnome-volume-control has changed since a few releases ago. I'm using Natty fwiw. Ideas?

  • Do you believe it's a good idea for Software Engineers to have to work as Quality Assurance Engineers for some period of time?

    - by Macy Abbey
    I believe it is. Why? I've encountered many Software Engineers who believe they are somehow superior to QA engineers. I think it may help quench this belief if they do the job of a QA engineer for some time, and realize that it is a unique and valuable skill-set of its own. The better a Software Engineer is at testing their own programs, the less cost in time their code incurs when making its way through the rest of the software development life-cycle. The more time a Software Engineer spends thinking about how a program can break, the more often they are to consider these cases as they are developing them, thus reducing bugs in the end product. A Software Engineer's definition of "complete" is always interesting...if they have spent time as a QA engineer maybe this definition will more closely match the designer of the software's. What do you all think?

  • Is good practice to optimize FPS even when it's above the lower limit to give illusion of movement?

    - by rraallvv
    I started over 50 FPS on the iPhone, but now I'm bellow 30 PFS, I've seen most iPhone games clamped to either 60 or 30 FPS, even when 24 or less would give the illusion of movement. I've concidered my limit to be a little bit over 15 FPS, in fact my physics simulation is updated at that rate (15.84 steps/s) as that is the lowest that still give fluid movement, a bit lower gives jerky motion. Is there a practical reason why to clamp FPS way above the lower limit? Update: The following image could help to clarify I can independently set the physic simulation step, frame rate, and simulation interval update. My concern is why should I clamp any of those to values greater than the minimum? For instance to conserve battery life I could just to choose the lower limits, but it seems that 60 or 30 FPS are the most used values.

  • JavaFX - the right way to use Properties with domain objects

    - by pjm56
    JavaFX has provided a bunch of new Property objects, such as javafx.beans.property.DoubleProperty which allow you to define fields which can be automatically observed and synchronised. In many JFX examples, the MVC model class has a number of these Property fields, which can then bind automatically to the view. However, this seems to be encouraging us to put JFX properties into our Domain objects (if you assume that the Model class is going to be a domain object), which strikes me as a poor separation of concerns (i.e. putting GUI code in the Domain). Has anyone seen this problem being solved in 'real life' and, if so, how was it done?
