  • Azure Blob storage defrag

    - by kaleidoscope
    The Blob Storage is really handy for storing temporary data structures during a scaled-out distributed processing. Yet, the lifespan of those data structures should not exceed the one of the underlying operation, otherwise clutter and dead data could potentially start filling up your Blob Storage Temporary data in cloud computing is very similar to memory collection in object oriented languages, when it's not done automatically by the framework, temp data tends to leak. In particular, in cloud computing,  it's pretty easy to end up with storage leaks due to: Collection omission. App crash. Service interruption. All those events cause garbage to accumulate into your Blob Storage. Then, it must be noted that for most cloud apps, I/O costs are usually predominant compared to pure storage costs. Enumerating through your whole Blob Storage to clean the garbage is likely to be an expensive solution. Lokesh, M

  • Is there a simpler way to create a borderless window with XNA 4.0?

    - by Cypher
    When looking into making my XNA game's window border-less, I found no properties or methods under Game.Window that would provide this, but I did find a window handle to the form. I was able to accomplish what I wanted by doing this: IntPtr hWnd = this.Window.Handle; var control = System.Windows.Forms.Control.FromHandle( hWnd ); var form = control.FindForm(); form.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; I don't know why but this feels like a dirty hack. Is there a built-in way to do this in XNA that I'm missing?

  • using x11 forwarding with ssh and vnc?

    - by simona
    I am working on a remote cluster via ssh with the -X option, because I need to visualize data and graphs, over a vpn protocol. Sometime due to the instability of the internet connection I lose my session. They told me I could use vnc in order to not lose my current session, so that if the internet connection drops I can reconnect and continue with my previously open session. What I do is to log in the remote cluster 'remote.cluster' and type vncserver :1 then I open another terminal on my system and I type ssh -C -NL 5901:remote.cluster:5901 [email protected] & Then I start vinagre on my system and I connect using ssh protocol. The problem is that I do not have x11 forwarding and I cannot open windows. If I try to connect using the vnc protocol with vinagre it doesn't connect, because I get something as connection timeout. What should I do?

  • Grub boot problems with older ubuntu

    - by denk doink
    This is my 1st post here and there are 2 problems that are inter-related. I'm not much of a Linux system person... the computer is a dedicated linux box without any windoze. 1) running 9.10 and had a boot failure last week. looks like a file was deleted or corrupted. i was unable to get it to work. realizing it was a boot issue, i took the CD and installed 9.04 to co-exist with 9.10 on the disc. 9.04 was put into a 2.5 gb ext3 partition. i was able to boot into 9.10 from grub menu selection. 9.04 was now the default in grub menu. 2) i want to remove/delete/purge 9.04 completely from my system and "clean up" the stuff so that the machine boots straight to 9.10 (no grub menu). how are these accomplished in a "safe" manner? thank you. -denk

  • Sound Problem due to wrong driver installation

    - by Starx
    First of all, the audio used to play from the speaker but whenever I connected a headphone or speaker in the I, the sound didn't came. So I installed a realtek sound driver to fix this (actually I didn't find any relevant driver for my sound card so I installed it hoping it would show some light) When I rebooted the system, my sound is completely gone and now ubuntu does not detect any sound devices in my system. I clearly installed wrong driver, now I need to remove and go to previous stage and find a correct driver. My laptop is: Dell Studio 1747, uses a speaker Creative Labs Sound X-Fi MB Sound Blaster and the chipset is INTEL PM55. How can I fix this?

  • Software requirements specification, please help!

    - by Nicholas Chow
    For a school project, I had to create a SRS for a "fictional" application. However they did not show us what it exactly entails, and were very vague with explanations. The SRS asked of us has to have at least 5 functional requirements, 5 non functional requirements and 1 constraint. Now I have tried my best to make one however I think there are still a lot of mistakes in it. Could you all please look at it and provide me with some feedback on which parts I can improve or just tell me which parts are plain out wrong and how to make it better? (The project has a maximum of 12 pages so it is a bit long, I will post it below. FR1 Registration of Organizer FR1 describes the registration of an Organizer on CrowdFundum FR1.1 The system shall display a registration form on the website. FR1.2 The system shall require a Name, Username, Document number passport/ID card, Address, Zip code, City, Email address, Telephone number, Bank account, Captcha code on the registration form when a user registers.

  • Carpool logical architecture

    - by enrmarc
    I'm designing a carpool system (drivers can publish their routes and passengers can subscribe to them) with WebServices(axis2) and Android clients (ksoap2). I have been having problems with the logical architecture of the system and I wondered if this architecture is fine. And another question: for that architecture (if it is ok), how would be the packages structure? I suppose something like that: (In android) package org.carpool.presentation *All the activities here (and maybe mvc pattern) (In the server) package org.carpool.services *Public interfaces (for example: register(User user), publishRoute(Route route) ) package org.carpool.domain *Pojos (for example: User.java, Route.java, etc) package org.carpool.persistence *Dao Interface and implementation (jdbc or hibernate)

  • How to use American English spelling dictionary in Firefox?

    - by mmr
    My Firefox spellchecker was complaining this morning that I spelled 'neighbor' in the American English style, not the British English style ('neighbour'). Same is true for color (colour), analyze (analyse), etc. I've checked in the edit-preferences-content-language tab, and en-us is selected. I also found this link here: http://ubuntuforums.org/showthread.php?t=1013043 Suggesting that there's some kind of system panel I can use to ensure that I've got the right language, but I can't see where that is (I guess that's for an older Ubuntu that let people get to system settings). So either the dictionary for Firefox for en-us is corrupted, just a copy of the British English dictionary, or somehow the setting isn't propagated properly. How can I get the American dictionary back?

  • How do software projects go over budget and under-deliver?

    - by Carlos
    I've come across this story quite a few times here in the UK: NHS Computer System Summary: We're spunking £12 Billion on some health software with barely anything working. I was sitting the office discussing this with my colleagues, and we had a little think about. From what I can see, all the NHS needs is a database + middle tier of drugs/hospitals/patients/prescriptions objects, and various GUIs for doctors and nurses to look at. You'd also need to think about security and scalability. And you'd need to sit around a hospital/pharmacy/GPs office for a bit to figure out what they need. But, all told, I'd say I could knock together something with that kind of structure in a couple of days, and maybe throw in a month or two to make it work in scale. * If I had a few million quid, I could probably hire some really excellent designers to make a maintainable codebase, and also buy appropriate hardware to run the system on. I hate to trivialize something that seems to have caused to much trouble, but to me it looks like just a big distributed CRUD + UI system. So how on earth did this project bloat to £12B without producing much useful software? As I don't think the software sounds so complicated, I can only imagine that something about how it was organised caused this mess. Is it outsourcing that's the problem? Is it not getting the software designers to understand the medical business that caused it? What are your experiences with projects gone over budget, under delivered? What are best practices for large projects? Have you ever worked on such a project? EDIT *This bit seemed to get a lot of attention. What I mean is I could probably do this for say, 30 users, spending a few tens of thousands of pounds. I'm not including stuff I don't know about the medical industry and government, but I think most people who've been around programming are familiar with that kind of database/front end kind of design. My point is the NHS project looks like a BIG version of this, with bells and whistles, notably security. But surely a budget millions of times larger than mine could provide this?

  • Accessing SSRS Report Manager on Windows 7 and Windows 2008 Server

    - by Testas
      Here is a problem I was emailed last night   Problem   SSRS 2008 on Windows 7 or Windows 2008 Server is configured with a user account that is a member of the administrator's group that cannot access report Manager without running IE as Administrator and adding  the SSRS server into trusted sites. (The Builtin administrators account is by default made a member of the System Administrator and Content Manager SSRS roles).   As a result the OS limits the use of using elevated permissions by removing the administrator permissions when accessing applications such as SSRS     Resolution - Two options   Continue to run IE as administrator, you must still add the report server site to trusted sites Add the site to trusted sites and manually add the user to the system administrator and content manager role Open a browser window with Run as administrator permissions. From the Start menu, click All Programs, right-click Internet Explorer, and select Run as administrator. Click Allow to continue. In the URL address, enter the Report Manager URL. Click Tools. Click Internet Options. Click Security. Click Trusted Sites. Click Sites. Add http://<your-server-name>. Clear the check box Require server certification (https:) for all sites in this zone if you are not using HTTPS for the default site. Click Add. Click OK. In Report Manager, on the Home page, click Folder Settings. In the Folder Settings page, click Security. Click New Role Assignment. Type your Windows user account in this format: <domain>\<user>. Select Content Manager. Click OK. Click Site Settings in the upper corner of the Home page. Click security. Click New Role Assignment. Type your Windows user account in this format: <domain>\<user>. Select System Administrator. Click OK. Close Report Manager. Re-open Report Manager in Internet Explorer, without using Run as administrator.   Problems will also exist when deploying SSRS reports from Business Intelligence Development Studio (BIDS) on Windows  7 or Windows 2008, therefore you should run Business Intelligence Development Studio as Administor   information on this issue can be found at <http://msdn.microsoft.com/en-us/library/bb630430.aspx>

  • Why don't research papers that mention custom software release the source code?

    - by Antoine
    Is there a reason why the source code of softwares mentioned in research papers is not released ? I understand that research papers are more about the general idea of accomplishing something than implementation details, but I don't get why they don't release the code. For example, in this paper ends with: Results The human line drawing system is implemented through the Qt framework in C++ using OpenGL, and runs on a 2.00 GHz Intel dual core processor workstation without any additional hardware assistance. We can interactively draw lines while the system synthesizes the new path and texture. Do they keep the source code closed intentionally because of a monetization they intend to make with it, or because of copyright ?

  • Books or help on OO Analysis

    - by Pat
    I have this course where we learn about the domain model, use cases, contracts and eventually leap into class diagrams and sequence diagrams to define good software classes. I just had an exam and I got trashed, but part of the reason is we barely have any practical material, I spent at least two good months without drawing a single class diagram by myself from a case study. I'm not here to blame the system or the class I'm in, I'm just wondering if people have some exercise-style books that either provide domain models with glossaries, system sequence diagrams and ask you to use GRASP to make software classes? I could really use some alone-time practicing going from analysis to conception of software entities. I'm almost done with Larman's book called "Applying UML and Patterns An Introduction to Object-Oriented Analysis and Design and Iterative Development, Third Edition". It's a good book, but I'm not doing anything by myself since it doesn't come with exercises. Thanks.

  • Parallel Installation of Ubuntu, Wubi and Windows 7?

    - by Aufwind
    I have Windows 7 installed on a Notebook. Because I wanted to experiment with Ubutnu without loosing my Windows 7 configuration I installed the Wubi Version of Ubuntu inside of Windows 7. Since things seam to work out well with Ubuntu and my harddisk space is very limited, I want to make Ubuntu my only operating system on this machine. So my question is: Is it possible, to install Ubuntu 11.04 additionally to my actual configuration (Wubi and Windows 7)? And if things turned out well with the native installation of Ubuntu, too, to delete Wubi and Windows 7 from my system afterwards? Why I am asking this is simply, that I am afraid, that if I just format my machine and made the whole harddisk available for the fresh Ubuntu installation, it could be possible, that it turns out, that one thing or an other would not work properly, like it did in Wubi. (Possible Network, VPN, and Firewall@work issues) In this case I'd like the possibility to switch back.

  • Are there well-known PowerShell coding conventions?

    - by Tahir Hassan
    Are there any well-defined conventions when programming in PowerShell? For example, in scripts which are to be maintained long-term, do we need to: Use the real cmdlet name or alias? Specify the cmdlet parameter name in full or only partially (dir -Recurse versus dir -r) When specifying string arguments for cmdlets do you enclose them in quotes (New-Object 'System.Int32' versus New-Object System.Int32 When writing functions and filters do you specify the types of parameters? Do you write cmdlets in the (official) correct case? For keywords like BEGIN...PROCESS...END do you write them in uppercase only? It seems that MSDN lack coding conventions document for PowerShell, while such document exist for example for C#.

  • Resources for popular domain models

    - by Songo
    I have come across many situations where I had to build a system for a library or a clinic or other popular domains. The thing is a domain model for a library was probably done 1000 times already with different level of details of course. Here is an example. Is there a popular website or community where one can find ready made domain models for popular systems? The whole purpose I'm trying to achieve is to quickly get a grasp of the domain I'm modeling and customize it to my needs. Re-inventing the wheel seems really absurd when the same system might have been modeled properly previously. Note I know Google might sound like the perfect source, but there is a repository out there that people can post there models, so that others can share them.

  • Apple Developer Enterprise Program?

    - by Gnial0id
    I'm building an iOS application for a client (not an enterprise but non-profit association with under than 500 employess), distributed in a free version and a "paid" one. The free version will be available with iTunes/AppStore, no problem with that. But about the paid one... the distribution my client wants is different. They want to distribute it to their clients as a bonus in their subscription, and so, to control this distribution. The first answer would be "iOS Developer Enterprise Program", but it's not an enterprise and have less than 500 employees. Will the fact that my client will distribute the app' with a subscription be a problem ? I spend a lot of time to read documentation, but it is not very clear. I'm a bit lost, I admit it. Any help would grateful.

  • How do I totally disable all forms of session management in Xubuntu?

    - by Evan Carroll
    Xubuntu remembers things like xfce-terminal and chromium whenever my system starts up. I don't want that function to happen, ever. I want every restart to be fresh. How do I disable this functionality. I've seen numerous tutorials that unchecking the "Save sessions for future logins" screen in Log Off would work, but it does't seem to work for me. When the system comes back the other applications are open. I've also deleted the files in autostart, as per this question.
