  • 5 ways to stop code thrashing&hellip;

    - by MarkPearl
    A few days ago I was programming on a personal project and hit a roadblock. I was applying the MVVM pattern and for some reason my view model was not updating the view when the state changed??? I had applied this pattern many times before and had never had this problem. It just didn’t make sense. So what did I do… I did what anyone would have done in my situation and looked to pass the blame to someone or something else. I tried to blame one of the inherited base classes, but it looked fine, then to Visual Studio, but it seemed to be fine and eventually to any random segment of code I came across. My elementary problem had now mushroomed into one that had lost any logical basis and I was in thrashing mode! So what to do when you begin to thrash? 1) Do a general code cleanup – Now there is a difference between cleaning code and changing code . When you thrash you change code and you want to avoid this. What you really want to do is things like rename variables to have better meaning and go over your comments. 2) Do a proof of concept – if cleaning code doesn’t help. The  you want to isolate the problem and identify the key concepts. When you isolate code you ideally want it to be in a totally separate project with as little complexity as possible. Make the building blocks and try and replicate the functionality that you are getting in your current application. 3) Phone a friend – I have found speaking to someone else about the problem generally helps me solve any thrashing issues I am having. Usually they don’t even have to say anything to solve the problem, just you talking them through the problem helps you get clarity of mind. 4) Let the dust settle – Sometimes time is the best solution. I have had a few problems that no matter who I discussed them with and no matter how much code cleaning I had done I just couldn’t seem to fix it. My brain just seemed to be going in circles. A good nights rest has always helped and often just the break away from the problem has helped me find a solution. 5) Stack overflow it – So similar to phone a friend. I am really surprised to see what a melting pot stack overflow has been and what a help it has been in solving technology specific problems. Just be considerate to those using the site and explain clearly exactly what problem you are having and the technologies you are using or else you will probably not get any useful help…

  • What is SOA ?

    - by llaszews
    First, let’s mention what SOA is not: • SOA is not the same thing as web services. Web Services implies the use of standard such as Java/JAX-RPC, .NET or REST. Web Services also implies the use of a WSDL, SOAP, and/or J2EE Connector Architecture (J2EE CA) and HTTP. SOA architectures can be implemented using J2EE CA, XML file transfer or Remote Procedural Call (RPC) over File Transfer Protocol (FTP), TCP/IP, Remote Method Invocation (RMI) or other protocols. In other words, Web Services are a very specific set of technologies. SOA is a concept and can be implemented in many different ways. Some very rudimentary, such as transfering flat files between applications. • SOA will not solve all of your problems. It will make your business more agile, increase business visibility, reduce integration costs and provide better reuse. However, if you don’t need help in these area or expect SOA to cure all of your IT problems, you are looking in the wrong place. • The concepts behind SOA are not new, but SOA is also not mature. SOA as it stands today has really only been around for 5 years. The concepts of standards based protocol handlers, predefined communication schemas and remote method invocation have been around for decades. So, what is SOA? SOA is an architectural blueprint, a way of developing applications, and a set of best practices. SOA is not an ‘out of the box’ solution you buy, install and then have up and running in a matter of months. SOA is a journey to a better way of doing business and the technology architecture to support this better way of doing business. SOA is also a broader set of technologies including more then just web services. Techologies like an Enterpirse Service Bus (ESB), Business Processs Execution Language (BPEL), message queues and Business Activity Monitoring (BAM) all are part of a SOA architecture.

  • Well-tested libraries for player ratings?

    - by Lucky
    It's common in games to implement some sort of numerical ranking system -- the ELO system is usually used in chess. I could implement this system naively using Wikipedia's descriptions, but I suspect that this would open up a whole box of problems that have already been solved: rating inflation, etc -- for instance, the ELO system has a K constant that's 'fudged' according to rating, duration, pairings, statistics, ... What are some libraries (I'm looking at Python, but anything is okay) that implements rating systems? It also doesn't have to be ELO.

  • Compiz crashes after login

    - by T.Kijas
    after I log-in into Unity, compiz effects are disabled and it says compiz crashes. Restart of them usually works, but not every time. After restart of compiz, compiz works without problems, every effect is OK. I tried latest NVIDIA drivers from xorg-edgers, but situation is the same. I tried to delete folder with compiz settings, but it hasn't helped. I use two LCDs, but with only one enabled, the situation is the same. Thank you for suggestions.

  • Sharepoint Guidance Logger: usage, setup and extension

    - by spano
    Introduction Log records are essential to any application for troubleshooting problems. When beginning a new Sharepoint project, one of the first needs is to have a core logging component that can be used throughout the application code. In this post I will talk about the logging solution that we are using (based on the Patterns & Practices Sharepoint Logger ), how to set it up, configure and read logs. SharePoint 2010 includes enhanced functionality for logging and tracing. You can now throttle...(read more)

  • How to process large files in NetLogo? [closed]

    - by user65597
    I am running into problems in NetLogo with large *.csv / *.txt files. The documents can consist of about 1 million data sets and I need to read them (to eventually create a diagram based on the data). With the most straightforward source code, my program needs about 2 minutes to process these files. How should I approach reading such large data files faster in NetLogo? Is NetLogo even suitable for such tasks (as it seems to be designed more for teaching and learning)?

  • What is a clean Agile (Scrum) Sprint Presentation?

    - by negarnil
    Suppose someone of your development team is presenting a sprint to the customer but he is having web connection problems such that a complete story cannot be presented. For the sake of the cleanness of the presentation, do you help your colleague suggesting possible solutions and try to fix it in the moment? Or is it kind of messy? May be the customer (who is "part" of the team) will understand? Why?

  • How can I Connect My Nokia C6-01 to any music player?

    - by iasi
    I have a problem with Ubuntu 11.10. I can connect my Nokia C6-01 as a Massive Storage and Ubuntu will recognize it like a flash drive. But when I try to use Songbird, Rhythmbox, GMusic Browser and Amarok they arent even detecting it. I checked the add ons in everyone of them and they all have the mtp one. I want to be able to synchronize without problems my phone´s music but it´s so annoying to drag and drop my music and podcasts.

  • Genetic Considerations in User Interface Design

    - by John Paul Cook
    There are several different genetic factors that are highly relevant to good user interface design. Color blindness is probably the best known. But did you know about motion sickness and epilepsy? We’ve been discussing how genetic factors should be considered in user interface design in one of my classes at Vanderbilt University School of Nursing. According to the National Library of Medicine, approximately 8% of males and 0.5% of females have red-green color discrimination problems with the most...(read more)

  • Live-Ubuntu 12.04 ran fine, now stopped booting!

    - by user89743
    I've seen similar problems to this several times in the forum, but mine is a bit different, so the other posts I saw were no help to me. When I boot Ubuntu 12.04 64-bit from live-SD-card (3GB persistence) I suddenly get this error: (initramfs) mount: mounting /dev/loop0 on //filesystem.squashfs failed: Invalid argument Can not mount /dev/loop/0 (/cdrom/casper/filesystem.squashfs) on //filesystem.squashfs (it says I can type "help" for commands, but I don't know anything about how to go from there, totally new to linux) The reason I say my case is different is because my Ubuntu worked fine for over a week, even pretty fast, and now this problem happened. Before that I used to run my live ubuntu from USB sticks but that was slower (especially when booting which took 15 minutes from USB stick!). Also I kept getting the same above problem after a while when booting and had to re-create a live USB linux several times. Installing on harddrive is not an option because my harddrive has physical damage and getting a replacement will take a while, therefore I can only use live-USB or live-SD-card Ubuntu. As I said I used Ubuntu without problems for more than a week, before that as well for several weeks on USB sticks, but the above problem occured sooner or later. This time I paid attention to when it happened: I was rebooting my computer (HP 620 laptop, 4 GB RAM, 64 bit system) from SD flash card and when I was booting I selected F6 and then the first option "no acpi" or something like that...I had used it before and noticed it slowed down the time it took Linux to use. This time it caused this error. Now even when I boot normally/default I get this error. Now I'm accessing Ubuntu from my USB stick without persistence file, when I check my SD card, all the files mentioned in the error message are there and the filesystem.squashfs is 691.2 MB so nothing seems to have been deleted by accident. (I have already made many changes/downloaded programs to my SD card persistent Ubuntu and would hope to loose them, since downloading is expensive for me, and since the problem seems to re-occur...) Can anyone help me, preferably without having to create another startup disk on my SD card? I'm totally new to this. Sorry for the long posts, just didn't know what info is relevant and what isnt!

  • Ubuntu glitches up when i boot it

    - by aaron
    I recently installed Ubuntu on an old laptop of mine(HP Compaq Presario v6000), and I am having some problems. I installed everything and followed the guide like it said, but, when I try to boot up from hard drive it displays the desktop, but everything starts to glitch out and I can't click on any applications or scroll over them without it glitching, proceeded by a lock-up. I might re-install it to see if it helps, but if not, you guys got to help me out.

After restart of UbuntuONE, the CPU- usage shows 50% (100% core usage). Exit- command (from context-menu) hides the trayicon, but the program is still working excessive in background (50% cpu- / 50 MB memory- usage), until UbuntuOneClient.exe is killed by the taskmanager. What's going on ?

  • After update UBUNTU 12.04 changes wired interface from eth0 to eth1, network configuration fails

    - by Don McLaren
    I have been running UBUNTU 12.04 for a couple of months on this system with no problems. After a recent update, the bootup fails to define the wired network interface as eth0, so the default network configuration fails. ifconfig -a shows eth1 instead, as unconfigured. Booting from CD works OK, configures eth0 as normal. Solution: sudo NetworkManager The network manager figures out the situation, and configures eth1 Question: Where did this problem come from all of a sudden?

  • Companion Book for Cormen

    - by Robert S. Barnes
    I asked this question on Stackoverflow and they suggested it was more appropriate here. I"m taking a course soon based on the first fourteen chapters of Cormen's Introduction to Algorithms. The course is based on a translation of the 2003 edition. I have two questions: Is it recommended to get the newer 2009 edition and what are the differences? Can anyone recommend a good companion text which has more worked problems and less, "this clearly works" type explanations?

  • Kernel Panic Troubleshooting For Dummies

    - by iamsid
    I have made Ubuntu my primary OS since 10.04, and I have converted many of my friends and neighbors into Ubuntu users since then. I am the fix-it guy they approach when they encounter problems. The most frantic calls I get are when they encounter an "update-induced kernel panic." (Many human beings are allergic to command-line interfaces and search engines.) What are the step-by-step procedures to resolve an "update-induced kernel panic"?

  • How to connect to database on remote server

    - by user137263
    Where there is VPN to remote server and then access to the database via local network interface, how can one establish a remote link between one's computer (with a programme such as Visual Studio 2010) and SQL Server (e.g. 2008 R2) ? Any attempts to create a direct link to the SQL Server are blocked. Whilst the SQL Server can be configured to allow external access, this provides its own host of problems. Any help would be much appreciated.

  • Why are graphics so slow/jerky/lagged with an ATI 4250?

    - by Ben
    Never had a problem with Maverick, always very fast. I upgrade to Natty and the graphics seem to be very lagged. CPU, load, and memory usage is low, all graphics are choppy and lagged though. I have the proprietary driver installed and everything. Alt-Tabbing takes 3-5 seconds for the dialog to popup, zooming in with compiz zoom makes things very slow. I never had any of these problems with 10.10 Thanks

  • When is it reasonable to create my own programming language?

    - by Daniel Rikowski
    Are there types of killer applications, classes of algorithmic problems, etc., where it is better, in the long run, to create my own language? PS: Just to be sure, I mean a new programming language and a compiler, not a new compiler for an existing language. EDIT: Thank you for the answers. Can you provide some examples, where it is absolutly unnecessary to create a DSL or cases in which a DSL might be a good idea?

  • no login screen: problem with lightdm or plymouth?

    - by a different ben
    When I boot up my system, I don't get a login screen, just the boot log scrolling by, repeating after a while lines like this: * Starting anac(h)ronistic cron [ OK ] * Stopping anac(h)ronistic cron [ OK ] I can change to another virtual terminal, and start lightdm from there with sudo lightdm restart or sudo start lightdm. Other people with similar problems had just lightdm in their /etc/x11/default-display-manager. I've checked mine and it has /usr/sbin/lightdm in there, so that's not the problem.
