  • How do you track bugs in your personal projects?

    - by bedwyr
    I'm trying to decide if I need to reassess my defect-tracking process for my home-grown projects. For the last several years, I really just track defects using TODO tags in the code, and keeping track of them in a specific view (I use Eclipse, which has a decent tagging system). Unfortunately, I'm starting to wonder if this system is unsustainable. The defects I find are typically associated with a snippet of code I'm working on; bugs which are not immediately understood tend to be forgotten, or ignored. I wrote an application for my wife which has had a severe defect for almost 9 months, and I keep forgetting to fix it. What mechanism do you use to track defects in your personal projects? Do you have a specific system, or a process for prioritizing and managing them?

  • Who should map physical keys to abstract keys?

    - by Paul Manta
    How do you bridge the gap between the library's low-level event system and your engine's high-level event system? (I'm not necessarily talking about key events, but also about quit events.) At the top level of my event system, I send out KeyPressedEvents, KeyRelesedEvents and others of this kind. These high-level events only contain the abstract values of the keys (they don't say that Space way pressed, but that the JumpKey was pressed, for example). Whose responsibility should it be to map the "JumpKey" to an actual key on the keyboard?

  • How do I unlock a user account?

    - by John Kotrla
    I've been to system settings and to User Accounts. My account is the only one on the system and I have previously been able to UnLock the screen so that I could set my account to login without password prompt. That didn't make any effect on the system. I still have to enter a password to log in, but now I can't unlock the User Accounts dialog to make any changes at all. What do I need to reset? note how the unlock box in the upper right hand corner isn't available for selection...

  • ASP.NET Web Forms is bad, or what am I missing?

    - by iveqy
    Being a PHP guy myself I recently had to write a spider to an asp.net site. I was really surprised by the different approach to ajax and form-handling. For example, in the PHP sites I've worked with, a deletion of a database entry would be something like: GET delete.php?id=&confirm=yes and get a "success" back in some form (in the ajax case, probably a json reply). In this asp.net application you would instead post a form, including all inputs on the page, with a huge __VIEWSTATE and __EVENTVALIDATION. This would be more than 10 times as big as above. The reply would be the complete side again, with a footer containing some structured data for javascript to parse and display the result. Again, the whole page is sent, and then throwed away(?) since it's already displayed. Why not just send the footer with the data to parse (it's not json nor xml but a | separated list). I really can't see why you would design a system that way. Usually you've a fast client, and a somewhat fast server but a really slow connection. Why not keep the datatransfer to a minimum? Why those huge __VIEWSTATE and __EVENTVALIDATION? It seems that everything is done way to chatty and way to complicated. I really can't see the point and that usually means that I'm missing something. So please tell me, what are the reasons for this design and what benefits (and weaknesses) does it have? (Yes I know that __VIEWSTATE is used to tell what type of form-konfiguration should be sent back to the server. But WHY is this needed?) Please keep this discussion strictly technical and avoid flamewars. Update: Please excuse the somewhat rantish question. I tried to explain my view to be able to get a better answer. I am not saying that asp.net is bad, I am saying that I don't understand the meaning of those concepts. Usually that means that I've things to learn instead of the concepts beeing wrong. I appreciate the explanations about that "you don't have to do this way in asp.net", I'll read up on MVC and other .net technologies. However, there most be a reason for this site (the one I referred to) to be written the way it is. It's written by professionals for a big organisation with far more experience than what I've. Any explanation about their (possible) design choice would be welcome.

  • Hard Copies VS Soft Copies

    - by Garet Claborn
    Where do you draw the line and say, "OK, I'm actually going to print out this piece of code, spec, formula, or other info and carry it around but these pieces can stay on disk." Well, more importantly why do you draw the line there? I've encountered this a number of times and have some sort of vague conceptions beyond "oh now I'm REALLY stuck, better print this out." I've also found some quicksheets of basic specs to be handy. Really though, I have no particular logic behind what is useful to physically have available in the design and development process. I have a great pile of 'stuff' papers that seemed at least partially relevant at the time, but I only really use about a third of them ever and often end up wishing I had different info on hand. Edit: So this is what I'm hearing in a nutshell: Major parts of the design pattern Common, fairly static and prominently useful code (reference or specs) Some representation of data useful in collaborating or sharing with team Extreme cases of tough problem solving Overwhelmingly,almost never print anything.

  • Integrating Azure ServiceBus and SharePoint 2010

    - by Sahil Malik
    SharePoint 2010 Training: more information My new article is finally online. I had been waiting for this for a while. The thing is, AppFabric became .NET 4, and left SharePoint 2010 behind. But fear not, we have REST API. But that brings up interesting challenges of how we can integrate Azure Service Bus with SharePoint 2010 (yes 2010, not vNext – I’m not giving NDA information out you fool), the design patterns you can use, figuring out challenging issues like security, sessions, and just app design patterns instead. Well, I hope you like my next article, SharePoint Applied: Azure ServiceBus and SharePoint 2010 Enjoy! Read full article ....

  • Installing software on an offline Ubuntu server

    - by Muhammad Gelbana
    Assuming that I have a server with Ubuntu server newly installed on it. I was thinking of installing the very same version on Virtual Box (Or any other virtualization software), connect it to the internet and use apt-get to only download the packages for upgrading the system and the new software such as (tomcat7, openjdk6-default-headless..etc). Then copy the downloaded packages from the archive folder to the offline server's archive folder through a USB stick. So now the virtual system won't actually be upgraded nor have any new software installed. But would running the very same apt-get commands on the offline system without the download directive -d be executed without issues ? *EDIT:*This needs to be as simple as possible because I'll have to write a guide for our client to do this on his own and so it won't be acceptable to require deep Linux knowledge to do this.

  • How to increase the bus factor and specialize at the same time?

    - by bizso09
    In agile pair programming it is recommended to switch pairs every now and then so as to increase the bus factor of the team. That means, most people in the team should work on different parts of the system at different times so that everyone has an understanding of it. Now it is impssible that everyone has an expert level of understanding of each part of the system. That's because people are urged to specialize in one area of expertise. If you are an expert database admin, what's the point of working on the user interface of the system when you switch pairs? You will not be able to do such a high quality job as someone who has extensive experience in UI design. How can you increase the bus factor and make sure that you have specialization in your team?

  • Dealing with coworkers when developing, need advice [closed]

    - by Yippie-Kai-Yay
    I developed our current project architecture and started developing it on my own (reaching something like, revision 40). We're developing a simple subway routing framework and my design seemed to be done extremely well - several main models, corresponding views, main logic and data structures were modeled "as they should be" and fully separated from rendering, algorithmic part was also implemented apart from the main models and had a minor number of intersection points. I would call that design scalable, customizable, easy-to-implement, interacting mostly based on the "black box interaction" and, well, very nice. Now, what was done: I started some implementations of the corresponding interfaces, ported some convenient libraries and wrote implementation stubs for some application parts. I had the document describing coding style and examples of that coding style usage (my own written code). I forced the usage of more or less modern C++ development techniques, including no-delete code (wrapped via smart pointers) and etc. I documented the purpose of concrete interface implementations and how they should be used. Unit tests (mostly, integration tests, because there wasn't a lot of "actual" code) and a set of mocks for all the core abstractions. I was absent for 12 days. What do we have now (the project was developed by 4 other members of the team): 3 different coding styles all over the project (I guess, two of them agreed to use the same style :), same applies to the naming of our abstractions (e.g CommonPathData.h, SubwaySchemeStructures.h), which are basically headers declaring some data structures. Absolute lack of documentation for the recently implemented parts. What I could recently call a single-purpose-abstraction now handles at least 2 different types of events, has tight coupling with other parts and so on. Half of the used interfaces now contain member variables (sic!). Raw pointer usage almost everywhere. Unit tests disabled, because "(Rev.57) They are unnecessary for this project". ... (that's probably not everything). Commit history shows that my design was interpreted as an overkill and people started combining it with personal bicycles and reimplemented wheels and then had problems integrating code chunks. Now - the project still does only a small amount of what it has to do, we have severe integration problems, I assume some memory leaks. Is there anything possible to do in this case? I do realize that all my efforts didn't have any benefit, but the deadline is pretty soon and we have to do something. Did someone have a similar situation? Basically I thought that a good (well, I did everything that I could) start for the project would probably lead to something nice, however, I understand that I'm wrong. Any advice would be appreciated, sorry for my bad english.

Then another message pop-out after Ubuntu loading screen this time the message is this: Gave up waiting for root device. Common problems: -Boot args (cat /proc/cmdline) -check rootdelay= (did the system wait long enough?) -check root= (did the system wait for the right device?) -missing module (cat /proc/module: ls /dev) ALERT! /dev/disk/by/by_uuid/EODC2345DC231576 does not exist.

  • Mount to /dev/sdb1 without password

    - by Jarmo
    I am unable to mount a USB drive (or SD card) to my system without root access. When I plug in a USB drive, it is visible in the left column of Nautilus, but when I click on it to open it, I receive the error message Unable to mount 2.1 GB Filesystem Error mounting: mount exited with exit code 1: helper failed with: mount: only root can mount /dev/sdb1 on /media/sdb1 I am able to mount the drive using sudo mount -w /dev/sdb1, but this causes problems for operations such as creating startup discs, which requires unmounting and remounting the drive. I suspect this problem may be caused by the fact that when I upgraded from 11.10 to 12.04, I had an SD card plugged in. This caused the system to stall during later startups, as it could not find this drive. I remedied this by editing a line of /etc/fstab to read /dev/sdb1 /media/sdb1 vfat noauto 0 0 However, I am dual booting Ubuntu with Windows XP, and I have no problem mounting the C: drive of the Windows system without root access, so I feel that this is a problem related to the mount point rather than mounting in general.

  • Drag and drop fearture for a website

    - by gpuguy
    I have to design a website which will have drag and drop features for creating an e-card. So you select items from a tool box and drag and drop this item on the card area. Once you have completed the design you can publish the e-card on the web by clicking "Save and publish" button. What are the possible technologies for implementing this feature? The requirement is that the application should not degrade the performance of the website, and should not take much time in publishing once the user click "Save and publish" button.

  • Our Favorite Highlights from OpenWorld 2012

    - by Kathy.Miedema
    By Kathy Miedema and Misha Vaughan, Oracle Applications User Experience The Oracle Applications User Experience (UX) team’s activities around OpenWorld expand every year, but this year we certainly raised the bar.   Members of our team helped deliver three, separate, all-day training events in the week prior to OpenWorld. Our Fusion User Experience Advocates (FXA) and Applications UX Sales Ambassadors (SAMBA) have all-new material around the Oracle user experience to deliver at conferences in the coming year - Fusion Applications design patterns, mobile design patterns, and the new face of Fusion. We also delivered a hands-on workshop sharing user experience tools for our customers that is designed to answer this question: "If I have no UX staff, what do I do?" We also spent the weeks just before OpenWorld preparing to talk about the new face of Fusion Applications, a greatly simplified entry experience into Fusion Applications for self-service users, CRM users, and IT managers who want to change the look and feel quickly. Special thanks to Oracle ACE Director Floyd Teter for the first mention of our project.Jeremy Ashley, VP, Oracle Applications User Experience Customers may have seen one of the many OpenWorld session demos of the new face of Fusion, which will be available with Fusion Applications soon. It was shown in sessions by Oracle's Chris Leone, Anthony Lye, and our own Vice President, Jeremy Ashley, among others.   Leone reinforced the importance of user experience as one of three main design principles for Fusion Applications, emphasizing that Fusion was designed from the beginning to be intelligent, social, and mobile. User experience highlights of the new face of Fusion, he said, included the need for "zero training," and he called the experience "easy to use." He added that deploying it for HCM self-service would be effortless.  Customers take part in a usability lab tour during OpenWorld 2012. Customers also may have seen the new face of Fusion on the demogrounds or during one of our teams' chartered lab tours at the end of the week. We tested other new designs at our on-site lab in the Intercontinental Hotel, next to Moscone West. Applications User Experience team members show eye-tracking and mobile demos at OOW. We were also excited to kick off new branches of the Oracle Usability Advisory Board, which now has groups in Latin America and the Middle East, in addition to North America and EMEA.   And we were pleasantly surprised by the interest in one of our latest research projects, Oracle Voice, which is designed to enable faster data input for on-the-go users. We offer a big thank-you to the Nuance demopod for sharing the demo with OpenWorld attendees.  For more information on our program and products like the new face of Fusion, please comment below.

  • Unwanted application starts automatically when I login

    - by Bakhtiyor
    When I log in to my Ubuntu system several applications that I added to startup list (by using System-Preferences-StartUp Application) start automatically. Last times I am seeing that among those startup applications there is also another one called "Konqueror" (which is a browser and browse me automatically http://unix.stackexchange.com/users/4458/bakhtiyor) which starts automatically. But I didn't add this application to startup list. I looked for every place that I knew to see why it was loading automatically but I could not find it. Could anybody help me to find out how that application is starting up automatically when a session starts please? Note that I don't have root permission in my system, because it is in my working place. I am using Ubuntu Desktop and GNOME. Thank you.

  • Can an object oriented program be seen as a Finite State Machine?

    - by Peretz
    This might be a philosophical/fundamental question, but I just want to clarify it. In my understanding a Finite State Machine is a way of modeling a system in which the system's output will not only depend on the current inputs, but also the current state of the system. Additionally, as the name suggests it, a finite state machine can be segmented in a finite N number of states with its respective state and behavior. If this is correct, shouldn't every single object with data and function members be a state in our object oriented model, making any object oriented design a finite state machine? If that is not the interpretation of a FSM in object design, what exactly people mean when they implement a FSM in software? am I missing something? Thanks

  • Kernel freezes with nvidia optimus and bumblebee on 12.04

    - by piovisqui
    I have a Sony VAIO with Intel i7-3520M and NVIDIA Corporation GK107M [GeForce GT 640M LE]. I installed bumblebee and nvidia drivers. They work almost fine, but the system freezes like in a kernel panic once every day. I can play Dota 2 with primusrun on it with 20-30fps 1080p. But when I do something simple as expanding the KDE calendar widget from the bottom right corner, the system hangs a lot and windows borders get another border. The system freezes in not very intensive graphic tasks, for instance, ALT+TAB with KWin effects or pressing ALT+F2 for poping up the launcher. How can I solve this? Info: I use KDE. Couldn't paste de logs here, check at pastebin: http://pastebin.com/SBet8fRQ

  • Generation 4 Modular Data Center

    - by kaleidoscope
    Microsoft’s launched Generation 4 Modular Data Center design at the PDC 09 - The 20-foot container built on container-based model. Microsoft says the use of server-packed containers – known as Pre-Assembled Components (PACs) – will allow it to slash the cost of building its new data centers. Completely optimized for outdoor use, with a design that relies upon fresh air (”free cooling”) rather than air conditioning. Its exterior is designed to draw fresh air into the cold aisle and expel hot air from the rear of the hot aisle.

Suse 11.4 boots on the same machine. Suse 12.4 does not boot. I think there may be an issue with the EFI / GPT system. I know very little about these systems. I really expected the machine to boot. What can I do to get the system to boot? Please direct me to a path to trouble shoot this problem. thanks Jeffrey

  • User eXperience

    - by Daniel Moth
    The last few months I have been spending a lot of time designing (and help design) the developer experience for the areas I contribute to (in future versions of Visual Studio). As a technical person who defines feature sets, it is easy to get engulfed in the pure technical side of things and ignore the details that ultimately make users "love" using the product to achieve their goal, instead of just "having to use" it. Engaging in UX design helps me escape that trap. In case you are also interested in the UX side of development, I thought I'd share an interesting site I came across: UX myths. In particular, I recommend reading myths 9, 10, 12, 13, 14, 15 and 21. Let me know if there are other UX resources you recommend… Comments about this post welcome at the original blog.

  • Does Ubuntu run well on an USB HDD?

    - by Klaus
    I have here a company notebook, and because the HDD is full encrypted, I cannot install an extra partition for another system that I would like to use in my free time. And I really need another system, because this crap Windows here with that much of anti-virus, anti-spyware, anti-whatever on it is so slow and annoying. What can I do? I could use an external USB HDD with another system. Because I would like to handle big files and so on, I don't want to use a USB stick. A USB 2.5 HDD + Ubuntu is what I think the best option. Here are my questions: Do I have to note something? Does Ubuntu run well on an external HDD? Do I have big performance problems (because of the USB HDD)? Should I buy a very fast HDD for much money or it is not that important? Any suggestions?
