  • SharePoint: UI for ordering list items

    - by svdoever
    SharePoint list items have in the the base Item template a field named Order. This field is not shown by default. SharePoint 2007, 2010 and 2013 have a possibility to specify the order in a UI, using the _layouts page: {SiteUrl}/_layouts/Reorder.aspx?List={ListId} In SharePoint 2010 and 2013 it is possible to add a custom action to a list. It is possible to add a custom action to order list items as follows (SharePoint 2010 description): Open SharePoint Designer 2010 Navigate to a list Select Custom Actions > List Item Menu Fill in the dialog box: Open List Settings > Advanced Settings > Content Types, and set Allow management of content types to No  On List Settings select Column Ordering This results in the following UI in the browser: Selecting the custom Order Items action (under List Tools > Items) results in: You can change your custom action in SharePoint designer. On the list screen in the bottom right corner you can find the custom action: We now need to modify the view to include the order by adding the Order field to the view, and sorting on the Order field. Problem is that the Order field is hidden. It is possible to modify the schema of the Order field to set the Hidden attribute to FALSE. If we don’t want to write code to do it and still get the required result it is also possible to modify the view through SharePoint Designer: Modify the code of the view: This results in: Note that if you change the view through the web UI these changes are partly lost. If this is a problem modify the Order field schema for the list.

  • Google is re-indexing pages after redirecting URLs from HTTP to HTTPS incorrectly

    - by SLIM
    I upgraded my site so that all pages have gone from using HTTP to HTTPS. I didn't consider that Google treats HTTPS pages differently than HTTP. I recreated my sitemap to so that all links now reflect the new HTTPS URLs and let it be for a few days. (Whoops!) Google is now re-indexing all the HTTPS pages. I have about 19k pages on the site, and Google has already indexed about 8k of the new HTTPS pages. The problem is that Google sees all of these as brand new pages when many of them have a long HTTP history. Of course most of you will recognize the problem, I didn't set up a 301 from the old HTTP to the new HTTPS URLs. Is it too late to do this? Should I switch my sitemap back to HTTP URLs and then 301 redirect to the new HTTPS URls? Or should I leave the sitemap as is, and setup 301 redirects anyway... I'm not even sure if Google is trying to reach the HTTP site anymore. Currently the site is doing 303 redirects (from HTTP to HTTPS), although I haven't figured out why yet.

  • Need help with ColdFusion and ASP.NET site [closed]

    - by Michael Stone
    To begin, I wasn't too sure how to title this.. I've got a few questions. First off, I've got a very big site that's in ColdFusion and we've been migrating to ASP.NET C# 4.0 the last 8 months. I've got a team of 7 programmers and no one can seem to figure out these answers, not even our senior C# programmer. We're using Team Foundation Server and we can't figure out how to only push up one small change at time. Right now we're stuck to publishing the entire site and it's causing serious issues. We've currently got the site as a Project and not a Website. We're wondering if that's one issue. I actually think it might be a problem. We're also dealing with an issue where we can't access our regular folders with relative paths. So we're first developing our admin side in .NET and We've got our regular site and then we've got another site within that for our .NET admin tools. By site, I'm referring to them actually being Sites in IIS. This also creates a problem for us when we're creating tools that upload images and want to store them and access them from our parent Site. I'd very much appreciate any advice on how to go about this in the most standardized way. So what I'm hoping for is advise on: -Publishing and managing a site/project in Team Foundation Server. Being able to push up one fix at a time if needed would be GREAT! -Any help figuring out the issuing referencing folders from my .NET child site to my parent ColdFusion site using regular relative paths. "/a/images/b/" would be nice nice instead of only being able to do "/b/images/" We're using ColdFusion 8, C# Asp.NET 4.0/Entity Framework/POCO Templates, and a Windows 2008 R2 Server. Thank you in advance for any help.

  • How do I install the nvidia driver for a GeForce 9300M?

    - by Alex
    Yesterday i've installed ubuntu 11.04 (instead of 10.10). And i need to install nvidia driver which supports opengl 3.3 In 10.10 i did it in a such way: Ctrl+alt+f1 login sudo /etc/init.d/gdm stop sudo sh driver.run startx Not it doesn't work. Because ctrl+alt+f1 doesn't show login screen. Just only black screen. I've googled this problem. Some people have it but no one knows how to solve. Sometimes people say that it is connected with video card or driver. But i have GeForce 9300M G, and i've activated a standard driver. Anyway, it worked in 10.10, but doesn't work now. The main problem is that i need to kill xserver to install this driver. killing the process just only restarts xserver. Also, I've tried to /etc/init.d/gdm stop in GUI-console. It says that "Fake initctl,doing nothing". Google didn't helped in this case too. Any ideas to install that driver?

  • How should an undergraduate programmer organize his time learning the maximum possible?

    - by nischayn22
    I started programming lately(pre-final year of a CS degree) and now feel like there's a sea of uncovered treasure for me out there. So, I decided to cover as much as is possible before I look out for a job after graduation. So, I started to read books (The C++ Programming Language, Introduction to Algorithms, Cracking the Coding Interview, Programming Pearls,etc ) participate in StackExchange sites, solving problems (InterviewStreet and ProjectEuler), coding for open source, chatting to fellow programmers/mentors and try to learn more and more. Good,then what's the problem?? The problem is I am trying to do many things, but I am doubtful that I am still utilizing my time properly. I am reading many books and sometimes I just leave a book halfway (jumping from one book to another), sometimes I spend way too much time on chatting and also in getting lost somewhere in the huge internet world, and lastly the wasteful burden of attending classes (I don't think my teachers know good enough or I prefer learning on my own) May be some of you had similar situation. How did you organize your time? Or what do you think is the best way to organize it for an undergraduate? Also what mistakes am I making that you can warn me of

  • ERP/CRM Systems. Desktop Based ? Web based? [closed]

    - by Parhs
    I have seen 2-3 ERPs in action. I am wondering what is better. Desktop based application or webbased displayed on a browser. My first experience was with a web based ERP when i was 14 years old.. It was web based and terribly slow... For most simple task you had to do lots of clicks... no keyboard support ..... Pages took ages to load. Last year I worked for migrating to a newer computer some old terminal based cobol application. The computer that worked till today and still has no problem was from 1993. The user interface ofcourse was textbased.. The speed that guys placed orders was amazing! just typing the name of the customer , then 5-10 keys to add a product to order.... Comparing to this ERP the page for placing orders Link (click sales orders) seems terribly slow to add a product... No keyboard shortcut works to save what you added and generally I believe you need 4 times more time to place an order compared to the text interface... Having to use both mouse and keyboard for this task is BAD and sadistic... So how can the heck these people ever use a system like that ??? So in the long run desktop application seems the only way... Of course browsers support shortcuts but the way to overide the defaults that browsers uses isn't cross compatible... That is a huge problem. Finnaly, if we MUST/forced use cloud in near future what about keyboard shortcuts?? I feel confused... I have seen converters of desktop applications to browser applications but are SLOW as hell... The question is what about user friendliness? What kind of application would you use?

  • Effective and simple matching for 2 unequal small-scale point sets

    - by Pavlo Dyban
    I need to match two sets of 3D points, however the number of points in each set can be different. It seems that most algorithms are designed to align images and trimmed to work with hundreds of thousands of points. My case are 50 to 150 points in each of the two sets. So far I have acquainted myself with Iterative Closest Point and Procrustes Matching algorithms. Implementing Procrustes algorithms seems like a total overkill for this small quantity. ICP has many implementations, but I haven't found any readily implemented version accounting for the so-called "outliers" - points without a matching pair. Besides the implementation expense, algorithms like Fractional and Sparse ICP use some statistics information to cancel points that are considered outliers. For series with 50 to 150 points statistic measures are often biased or statistic significance criteria are not met. I know of Assignment Problem in linear optimization, but it is not suitable for cases with unequal sets of points. Are there other, small-scale algorithms that solve the problem of matching 2 point sets? I am looking for algorithm names, scientific papers or C++ implementations. I need some hints to know where to start my search.

  • fwupd to update OCZ RevoDrive firmware gets a 'Permission denied' error

    - by Late
    Try as I might I just don't get it working (http://www.ocztechnology.com/ssd_tools/OCZ_RevoDrive_and_RevoDrive_X2/). There's another thread here with an similar issue here: Command is giving me "bash: ./fwupd: cannot execute binary file" I'm running command ./fwupd /dev/sdb which keeps returning me bash: ./fwupd: Permission denied I have tried running both bit versions available of fwupd with both of the latest 32- and 64-bit Ubunty 11.10, running the OS from an USB stick, but to no avail (could this be the problem?). In the other thread it was suggested that chmod +x fwupd (or chmod 0755 fwupd) should resolve this issue, but at least for me it has been for naught. It was also suggested to install certain libraries, but those were already included in the Ubunty build and I didn't have any luck after updating with apt-get. I also tried giving fwupd more privileges, r, x and w but same charade, run it in different ways from different places (where I'd have the fwupd present, ofc) among other things. What I also tried is giving the Ubunty 10.04 LTS a shot but it didn't even launch on either of my computers, though that's not the issue here. If anyone has any ideas on what the problem is and how I could get this working, it would be most appreciated!

  • Impossible quandrary involving UCK, graphics card, and Nvidia drivers

    - by InkBlend
    I have a computer that I want to install Ubuntu on. It is an older gaming computer with a Nvidia graphics card. When I attempt to boot any unmodified Linux distribution onto it, I get a "Boot error" message, which I assume is because the computer uses a discrete graphics card, which the Linux kernel does not have support for. Ordinarily, that would not be a problem, as I would just plug the monitor into the VGA port built in to the motherboard. However, this particular model of motherboard does not have an on-board graphics connector, so I am stuck with using the graphics card connection. That further would not be a problem; all I would have to do would be to use UCK to create a customized Ubuntu image that included the graphics drivers. Except for the fact that the Nvidia Linux drivers must be installed on a computer with a Nvidia graphics card present. So while using UCK, the driver installer fails with a message stating that there is no Nvidia graphics card present. How do I get Ubuntu on my desktop computer?

  • Grub2 attempting to boot hd1 when it should boot hd0

    - by JoBu1324
    I'm attempting to perform a "normal" install on a USB3 SSD (I don't know if it is noteworthy, but I don't have a swap partition). The installation proceeds normally (I'm installing from a USB2 device I created using LiLi Boot, with a copy of Ubuntu 12.10 64bit that I downloaded directly from the source. The system I'm running Ubuntu on has had a more traditional installation of ubuntu running on it without issue (also 12.10), so I know that everything works A-OK when booting from a 7200RPM internal disk. There are a number of oddities that I've noticed so far, including graphics corruption, but the first and most pressing issue is that Grub2 refuses to recognize the correct hd. From /boot/grub/grub.cfg: if [ x$feature_default_font_path = xy ] ; then font=unicode else insmod part_msdos insmod ext2 set root='hd1,msdos1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos1 --hint-efi=hd1,msdos1 --hint-baremetal=ahci1,msdos1 b58ee4f7-d41d-400a-b7b8-18bd1f0ae9d3 else search --no-floppy --fs-uuid --set=root b58ee4f7-d41d-400a-b7b8-18bd1f0ae9d3 fi font="/usr/share/grub/unicode.pf2" fi This is from a 100% fresh install of linux (first boot), which was installed while no hard drives were connected to the system, other than the USB2 LiLi drive. The system refuses to boot unless I change the hd1,msdos1 - hd0,msdos1 in the grub menu at boot, when it is the only disk device connected to the PC. What options are left for me to troubleshoot this issue? I've been racking my brains and taxing the internet trying to dig up something on this problem, but now I'd like to see if the Ubuntu community can rise to the challenge and help me fix this boot problem. This is the second time I've attempted this particular setup. The first time, after days of wasted time, I managed to get it to boot every other boot - i.e. every even boot it would boot into Ubuntu like it was happy; every odd boot it would boot into the BusyBox or Grub prompt. At one point it complained that it couldn't find /dev/disk/by-uuid/[the disk], which I found most perplexing, since the disk was there and booted before and after the occurrence (with intervention).

  • bash terminal/console strange overlapping behavior

    - by UpKey
    I am using gnome-terminal in Ubuntu 11.10 and seem to get long lines overlapping in the terminal window. When I copy a long command line and paste it into the terminal, the text gets overlapped to the start of the line and often covers the user prompt. If I resize the terminal window, making it wider the overlapping gets undone and everything looks normal. In previous versions of Ubuntu, if a line was too long it would continue on the next line below. Another problem I have noticed that may be related, is when using the up arrow key to show previously typed commands, sometimes instead of the output command line being replaced by the previous command each time the key is pressed, the lines get partially merged. A portion of the old line remains, and the next command gets joined onto the end. This leftover part of a command is persistent and does not get replaced next time the key is pressed, although the insertion point or blinking cursor is at the end of the latest recalled command, and the leftover has no effect if I press enter. Is this problem a bug or some setting that needs fixing? Where do I look for the cause? keyboard? gnome-terminal? bash? Thank you for any help or suggestions offered

  • Awesome and LXDE desktop managers messed up KDE

    - by Caleb1994
    I saw a desktop manager named "Awesome" earlier on Google+, and thought I'd give it a try. In short, I didn't like it, but it got me wondering what other desktops were like, which I hadn't tried. The first one to come to mind was LXDE. I installed that, and tried it. I wasn't a big fan, so I just went to log back into KDE. Only, when I log in, everything is screwy. My theme is weird (although, according to system settings, it is still the same). All the categories and application short cuts in the KMenu are gone, except my favorites, which are now renamed with the "short name", it seems. I know these things are global resources, so it is very likely that one of these Window Managers screwed it up, but I need it fixed. Actually, it seems that after restarting the theme problem fixed itself, but the KMenu items disappearing is still a problem. Does anyone know where these items are stored? (I know they are are just .desktop files somewhere, IIRC, but I don't remember where they are usually stored so I can see if they are still there). I'm hoping it's just a matter of a broken link or something somewhere, not deleted shortcuts... :/ In summary: Any ideas on what caused this? Do you know how to fix the KMenu, or at least where the .desktop shortcuts are stored for the KMenu so I can see if they still exist (crosses fingers).

  • webhost4life, please give me, my data back. My website will not work without the database.

    - by Shervin Shakibi
    I have about 4 or 5 accounts with WebHost4life.com, these are all my customers that based on my recommendation have been hosting with webhost4life.com. A few days ago for some reason they decided to migrate one of these accounts to a new server. They moved everything created a new database on the new server but the new database is empty. after spending hours with Tech support they acknowledged the problem and assured me it will take up to an hour or two and my database will be populated with the data. this was about 7 hours ago. Oh by the way I pay extra for the backup plan and yes you guessed it, none of my backups are there. Needless to say I’m very scared and disappointed. No one is responding to my emails  or phone calls. After searching the web, I found out, this has happened before, in some cases it took them days to fix the problem and many never got it resolved and switched hosting companies, I would love to do that but I need my 2 GB database before I start shopping around for a new hosting company. Stay away from Webhost4life.

  • Old Fglrx Driver - AMD Radeon HD 3200 - ubuntu won't start

    - by Yohannes
    I've been using Ubuntu 12.04 64 bit for about 2 weeks now and I installed the latest Fglrx driver (Graphics Card- AMD HD 3200, PC- Acer Aspire 5336, 4GB RAM, 500GB Harddrive). The problem is that sometimes video's lag and play out of sync sometimes the windows take long to show up after I've clicked them etc. After looking around I found a video on Youtube by Ubuntu help guy and in the video he recommended using an older driver if you have an older graphics card, his was about 4 years old (same as mine) and he used the 11.10 catalyst driver so I decided to try it. I removed the previous installation of the driver and then installed the 11.10 driver. However, when I restarted it instead of going to the GUI it goes to a terminal like window and asks for my login. Now its pretty clear I need to remove the old driver and go back to using the latest one. The only problem is I'm not sure where I saved the latest driver and in order to connect to the Internet I need to change /etc/resolv.conf (I use a static IP). So what should I do? Also anyone from personal experience, what propitiatory driver works best with my graphics card? As in the version. Thanks

  • How to justify rewriting/revamping legacy software in a business case?

    - by sxthomson
    I work for a great little software company which makes good revenue from our main software package. The problem for me is that it's almost unmaintainable. It's written in Delphi 7 (has upgraded versions over time) and has been worked on by a lot of developers over the past 20 or so years. The software lacks any meaningful architecture - there's no object orientation whatsoever, horrible amounts of cyclical dependencies and an over-reliance on global variables to name just a few things. Another huge thing for me is Delphi 7 does NOT support 64-bit. The problem here for me is that my management team don't care about technical things, they want to know why they should care. Obviously that's expected, so what I'm asking here is for some guidance, or tales, or pitfalls about this kind of thing. There's a few things I would love to include, namely for me, the length of time taken to debug/write a feature in "legacy" code, versus coherent, well structured OO code. Does anyone know of any blog posts or the like where this is talked about? For us in the company this is a huge reason. Despite being decent developers we feel like writing a new feature is just piling more rubbish on top. On top of that, even for me who has a decent level of understanding of the code, changing things is infuriating - a small change can have a ridiculous domino effect. Anyone have any experiences they'd like to share?

  • Bad Performance With Games Under Wine in Ubuntu 12.04

    - by Pandem
    I'm somewhat new to Linux. I've dabbled with it before but never more than just experimentation in a VM or dual boot where I almost always reverted back to Windows soon after (more due to a lack of commitment than a dislike for the OS). Anyway my problem is that in the two games (Guild Wars and Team Fortress 2) I've tried so far I get fairly bad performance. Despite both games having a "Platinum" rating I've still been forced to run both in DirectX 8, otherwise they either crash, have texture defects or the UI is missing. By "bad performance" I mean sub-30 FPS where there are some players and regular large framerate drops with video settings on low. Currently in my mind I believe the performance issues are just a problem with the drivers because my graphics card is a AMD 7850 which is virtually brand new and probably not properly supported yet but I'm unsure and would appreciate advice or tips to improve things. I have Ubuntu 12.04 installed and I am usually logged in a Gnome Classic session. I have installed AMD's proprietary drivers (Catalyst version 12.4) and have Wine 1.4 installed. I have used Winetricks to install DX9/DX10 dlls and other things.

  • Tips on how to notify a user of new features in your game (Android)

    - by brent777
    I have noticed a problem when releasing new features for a game that I wrote for Android and published on Google Play Store. Because my game is "stage-based" - and not a game like Hay Day, for example, where users will just go into the game every day since it can't really be finished - my users are not aware of new features that I release for the game. For example, if I publish a new version of my game and it contains a couple new stages, most of their devices will just auto-update the game and they don't even notice this and think to check out what's new. So this is why an approach like popping open a dialog that showcases the new feature(s) when they open the game for the first time after the update was done is not really sufficient. I am looking for some tips on an approach that will draw my users back into the game and then they could read more detail about new features on such a dialog. I was thinking of something like a notification that tells them to check out the new features after an update is done but I am not sure if this is a good idea. Any suggestions to help me solve this problem would be awesome.

  • How do I remove the tool tips on the launch bar?

    - by Sephethus
    The title is the question. These tool tips stay until I try to click past them. They're annoying since they constantly pop up and block the view of what I'm trying to do. Unfortunately I need the launch bar because Ubuntu is running on VMware and the console does not allow me to use the keyboard for switching tasks (to my knowledge). How do I disable them? I'd post an image as an example, but this site will not let me. UPDATE: unity 5.16.0 UPDATE 2: I discovered that this may only be a problem with users who run Ubuntu on a full screen VMware console that is situated on the right monitor. When the mouse is moved to the left monitor the tooltips popup and remain until the mouse is clicked twice in the VMware console window to make it active. Unfortunately my problem is one involving a rare situation I think. However, I'd love to be able to disable these tool tips if possible. It would also be nice if new features were added that can allow further customization of the launch bar.

  • Random compositing lag

    - by user1020567
    My laptop specs: 512 mb of RAM, out of which 64 mb are shared with an integrated GPU - ATI Radeon Xpress 200 M. Intel 1,6 Ghz Celeron M single-core processor. I've spent months trying to figure out why compositing and effects sometimes lag on any distro I try. Now I've come to realise that no matter what drivers I try (the default ones work for me on pretty much any linux) compositing lag is random. When I used Ubuntu 10.10, for example, sometimes window compositing would lag and sometimes it wouldn't. The PC is able to render those effects so hardware is not the problem. It's completely random and unpredictable - sometimes when I turn on the computer the effects lag horribly and sometimes it's completely smooth. I've also checked startup items and there doesn't seem to be any unnecessary entries. I also tried building my own OS with Arch Linux and the problem persists there, therefore I can only assume that it's a driver issue of some sort. By default there are lots of drivers supplied with linux distributions. Could it be that they're in the way? The ones that I need are ati/radeon (or both? What's the difference between them?) and there seem to be a lot of others... What should I do?

  • fresh install of ubuntu 12.04 using usb stick booted into tty1?

    - by croc
    I just installed ubuntu 12.04 alternate for the first time to give it a try using a usb stick burned with UnetBootIn. It installed without a problem. But it booted into a tty1 console without booting into a GUI. after loging into the tty1 console i typed 'unity'. it appeared that the system doesn't have unity desktop !!! How can it be solved ? My installation didn't show any error. Something worth mentioning: 1. during installation i had to choose an option saying 'customize the system to your needs' something like that i don't remember correctly with options 'SSH server','Mail Server', 'Ubuntu Desktop',.....,'Manual selection of packages' etc. I chose 'Ubuntu Desktop'. I haven't encountered something like this in ubuntu 11.04. to do an installation of alternate iso using UnetBootIn i used '12.04_Hdmedia' option of that software and had to change file extension of .ude to .udeb in /pool/main/l/linux that i found in Alternate ubuntu cdrom detect to go around with the cdrom detection problem. I have a 945G intel graphics.

  • pointers to member functions in an event dispatcher

    - by derivative
    For the past few days I've been trying to come up with a robust event handling system for the game (using a component based entity system, C++, OpenGL) I've been toying with. class EventDispatcher { typedef void (*CallbackFunction)(Event* event); typedef std::unordered_map<TypeInfo, std::list<CallbackFunction>, hash_TypeInfo > TypeCallbacksMap; EventQueue* global_queue_; TypeCallbacksMap callbacks_; ... } global_queue_ is a pointer to a wrapper EventQueue of std::queue<Event*> where Event is a pure virtual class. For every type of event I want to handle, I create a new derived class of Event, e.g. SetPositionEvent. TypeInfo is a wrapper on type_info. When I initialize my data, I bind functions to events in an unordered_map using TypeInfo(typeid(Event)) as the key that corresponds to a std::list of function pointers. When an event is dispatched, I iterate over the list calling the functions on that event. Those functions then static_cast the event pointer to the actual event type, so the event dispatcher needs to know very little. The actual functions that are being bound are functions for my component managers. For instance, SetPositionEvent would be handled by void PositionManager::HandleSetPositionEvent(Event* event) { SetPositionEvent* s_p_event = static_cast<SetPositionEvent*>(event); ... } The problem I'm running into is that to store a pointer to this function, it has to be static (or so everything leads me to believe.) In a perfect world, I want to store pointers member functions of a component manager that is defined in a script or whatever. It looks like I can store the instance of the component manager as well, but the typedef for this function is no longer simple and I can't find an example of how to do it. Is there a way to store a pointer to a member function of a class (along with a class instance, or, I guess a pointer to a class instance)? Is there an easier way to address this problem?

  • How to control messages to the same port from different emitters?

    Scene: A company has many factories X, each emits a message to the same receive port in a Biztalk server Y; if all messages are processed without much delay, each will trigger an outgoing message to another system Z. Problem: Sometimes a factory loses its connection for a half-day or more and, when the connection is reestablished, thousands of messages get emitted. Now, the messages still get processed well by Y (Biztalk can easily handle the load) but system Z can't handle the flood and may lock up and severely delay the processing of all other messages from the other X. What is the solution? Creating multiple receive locations that permits us to pause one X or another would lose us information if the factory isn't smart enough to know whether the message was received or not. What is the basic pattern to apply in Biztalk for this problem? Would some throttling parameters help to limit the flow from any one X? Or are their techniques on the end part of Y which I should use instead ? I would prefer this last one since I can be confident that the message box will remember any failures, which could then be resumed.

  • JiglibX addition to existing project questions

    - by SomeXnaChump
    Got a very simple existing project, that basically contains a lot of cubes. Now I am wanting to add a physics system to it and JiglibX seemed like the simplest one with some tutorials out there. My main problem is that the physics don't seem to be working how I imagined, I expected my tower of cubes to come crashing down, but they dont seem to do anything. I think my problem is that my cubes do not inherit DrawableGameComponent, they are managed by a world object that will update and render them. So they are at no point put into the games component list. I am not sure if this means that JiglibX will not be able to interact with them as in all the tutorials there are no explicit calls to add the Body objects to the physics system, so I can only presume that they are using a static/singleton under the hood which automatically hooks in all things, or they use the game objects component list somehow. I also noticed that in alot of the tutorials they use the following when setting up the physics system: float timeStep = (float)gameTime.ElapsedGameTime.Ticks / TimeSpan.TicksPerSecond; PhysicsSystem.CurrentPhysicsSystem.Integrate(timeStep); Would it not be better to keep a local instance of the created PhysicsSystem object and just call myPhysicsSystem.Integrate(timeStep)?

  • How do I troubleshoot system slowness seen when viewing PDFs or videos?

    - by asp
    Whenever I watch videos, either online of local via Totem and/or open PDF files using evince. The system gets really, really bogged down. All apps get really slow, menus take forever to display, switching windows gives me time to make a coffee, etc. I have a couple of bug reports open on this, but what do I need to do to really troubleshoot the issue? I've purged Adobe Flash from the system, but YouTube HTML5 videos still have the issue. A bunch of PDFs saved locally trigger the problem. And to (temporarily) remove the slowness, I need to shutdown the computer, breath for a few minutes, then restart. A simple reboot does not do the trick. How can I identify the cause? This only started on 13.04. I've had Ubuntu on this machine for a year without a problem until "upgrading" to 13.04. I am not a programmer, but I suspect an issue with the Intel video driver. Is there something I can run which will diagnose this, or are there concrete steps I can follow to find the culprit?
