• No drivers listed?/How to install all drivers? 12.10

  - by madmike59

  So i go to system settings in Ubuntu 12.10 and i want to install my drivers but under the Additional Drivers, My LAN doesnt work, Doesnt even pick up that im plugged in threw Ethernet cord. I have a GTX 670M with 3Gb GDDR5 for a video card and would like to use that. Just need help, pretty new to Ubuntu. Ok when i looked at that other question i did the sudo lspce -nn and this is what i got madmike@Mike-GT70:~$ sudo lspci -nn 00:00.0 Host bridge [0600]: Intel Corporation 3rd Gen Core processor DRAM Controller [8086:0154] (rev 09) 00:01.0 PCI bridge [0604]: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor PCI Express Root Port [8086:0151] (rev 09) 00:02.0 VGA compatible controller [0300]: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09) 00:14.0 USB controller [0c03]: Intel Corporation 7 Series/C210 Series Chipset Family USB xHCI Host Controller [8086:1e31] (rev 04) 00:16.0 Communication controller [0780]: Intel Corporation 7 Series/C210 Series Chipset Family MEI Controller #1 [8086:1e3a] (rev 04) 00:1a.0 USB controller [0c03]: Intel Corporation 7 Series/C210 Series Chipset Family USB Enhanced Host Controller #2 [8086:1e2d] (rev 04) 00:1b.0 Audio device [0403]: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller [8086:1e20] (rev 04) 00:1c.0 PCI bridge [0604]: Intel Corporation 7 Series/C210 Series Chipset Family PCI Express Root Port 1 [8086:1e10] (rev c4) 00:1c.2 PCI bridge [0604]: Intel Corporation 7 Series/C210 Series Chipset Family PCI Express Root Port 3 [8086:1e14] (rev c4) 00:1c.4 PCI bridge [0604]: Intel Corporation 7 Series/C210 Series Chipset Family PCI Express Root Port 5 [8086:1e18] (rev c4) 00:1d.0 USB controller [0c03]: Intel Corporation 7 Series/C210 Series Chipset Family USB Enhanced Host Controller #1 [8086:1e26] (rev 04) 00:1f.0 ISA bridge [0601]: Intel Corporation HM77 Express Chipset LPC Controller [8086:1e57] (rev 04) 00:1f.2 SATA controller [0106]: Intel Corporation 7 Series Chipset Family 6-port SATA Controller [AHCI mode] [8086:1e03] (rev 04) 00:1f.3 SMBus [0c05]: Intel Corporation 7 Series/C210 Series Chipset Family SMBus Controller [8086:1e22] (rev 04) 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation Device [10de:1213] (rev ff) 02:00.0 Ethernet controller [0200]: Atheros Communications Inc.

• PBCS Hyperion Planning in the Cloud Implementation Workshop

  - by Mike.Hallett(at)Oracle-BI&EPM

  Normal 0 false false false EN-GB X-NONE X-NONE MicrosoftInternetExplorer4 Oracle Planning and Budgeting Cloud Service (PBCS) opens up opportunities for organizations of all sizes to streamline planning and forecasting, accelerate deployment, and reduce costs. This one-day in-person workshop is delivered by Oracle Development (free to OPN member partners), and will cover the handoff from selling-to-implementing of PBCS. Although the basic building blocks are the same as with on-premises Planning, there is a paradigm shift when it comes to selling and implementing a Cloud Service solution. The value proposition behind Oracle Planning and Budgeting Cloud Service is all about the deployment model, how it’s sold and how it gets implemented – simplicity, fast adoption and flexible deployment, without sacrificing first-class functionality. To be successful, the entire cycle from sales to implementation should consistently support this value proposition to your clients. This training event is for OPN member partners whose business roles involve presales, implementation consulting, and support. This workshop briefly reviews the sales approach, as background, with emphasis on partner sales support. The main objective is to learn what is needed to successfully implement Oracle Planning and Budgeting Cloud Service once the sales hand off is made – how to leverage your current Hyperion Planning knowledge and use the features designed specifically to build out a Cloud Service solution. This Workshop is being offered at three locations for partners from all countries in EMEA: June 24, 2014: Kista, Sweden June 26, 2014: Reading, United Kingdom June 29-30, 2014 (split days): Dubaï, United Arab Emirates To get more information, to check pre-requisites, and to register, click here. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

• How do you conquer the challenge of designing for large screen real-estate?

  - by Berin Loritsch

  This question is a bit more subjective, but I'm hoping to get some new perspective. I'm so used to designing for a certain screen size (typically 1024x768) that I find that size to not be a problem. Expanding the size to 1280x1024 doesn't buy you enough screen real estate to make an appreciable difference, but will give me a little more breathing room. Basically, I just expand my "grid size" and the same basic design for the slightly smaller screen still works. However, in the last couple of projects my clients were all using 1080p (1920x1080) screens and they wanted solutions to use as much of that real estate as possible. 1920 pixels across provides just under twice the width I am used to, and the wide screen makes some of my old go to design approaches not to work as well. The problem I'm running into is that when presented with so much space, I'm confronted with some major problems. How many columns should I use? The wide format lends itself to a 3 column split with a 2:1:1 split (i.e. the content column bigger than the other two). However, if I go with three columns what do I do with that extra column? How do I make efficient use of the screen real estate? There's a temptation to put everything on the screen at once, but too much information actually makes the application harder to use. White space is important to help make sense of complex information, but too much makes related concepts look too separate. I'm usually working with web applications that have complex data, and visualization and presentation is key to making sense of the raw data. When your user also has a large screen (at least 24"), some information is out of eye sight and you need to move the pointer a long distance. How do you make sure everything that's needed stays within the visual hot points? Simple sites like blogs actually do better when the width is constrained, which results in a lot of wasted real estate. I kind of wonder if having the text box and the text preview side by side would be a big benefit for the admin side of that type of screen? (1:1 two column split). For your answers, I know almost everything in design is "it depends". What I'm looking for is: General principles you use How your approach to design has changed I'm finding that i have to retrain myself how to work with this different format. Every bump in resolution I've worked through to date has been about 25%: 640 to 800 (25% increase), 800 to 1024 (28% increase), and 1024 to 1280 (25% increase). However, the jump from 1280 to 1920 is a good 50% increase in space--the equivalent from jumping from 640 straight to 1024. There was no commonly used middle size to help learn lessons more gradually.

• How to generate SPMetal for a specific list (OOTB: like tasks or contacts) with custom columns

  - by KunaalKapoor

  SPMetal is used to make use of LINQ on a list in SharePoint 2010. By default when you generate SPMetal on a site you will get a code generated file for most of the lists and probably more. Here is a MSDN link for some info on SPMetal.http://msdn.microsoft.com/en-us/library/ee538255(office.14).aspxBut what if you want only to generate the code for one list?Well it is quite simple once you figure it out. You need to add an xml file to override the default settings of SPMetal and specify it in the /parameters option. I will show you how to do this.First create a Folder that will contain two files (GenerateSPMetalCode.bat and SPMetal.xml).Below is the content of the files:GenerateSPMetalCode.bat "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN\SPMetal" /web:http://YourServer /code:OutPutFileName.cs /language:csharp /parameters:SPMetal.xml pause SPMetal.xml <?xml version="1.0" encoding="utf-8"?> <Web AccessModifier="Internal" xmlns="http://schemas.microsoft.com/SharePoint/2009/spmetal"> <List Name="ListName"> <ContentType Name="ContentTypeName" Class="GeneratedClassName" /> </List> <ExcludeOtherLists></ExcludeOtherLists> </Web> You will have to change some of the text in the files so that it will be specific to your SharePoint Server Setup. In the bat file you will have to change http://YourServer to the url of the web where your list is. In the SPMetal.xml file you need to change ListName to the name of your list and the ContentTypeName to the name of the content type you want to extract. The GeneratedClassName can be anything but perhaps you should rename it to something more sensible.Adding the following line: '<List Name="ListName"><ContentType Name="ContentTypeName" Class="GeneratedClassName" /> </List>'  makes sure that any custom columns added to an OOTB list like contacts or tasks are also generated, which are missed out in a regular generation.So now when you run it the SPMetal command will read the SPMetal.xml list and override its commands. ExcludeOtherLists element makes it so that only the code for the lists you specify will be generated. For some reason I got an error if I had this element above the List element.You sould now have a code file called OutPutFileName.cs that has been generated. You can now put this in your SharePoint project for use with your LINQ queries against that list.I will soon write a LINQ example that uses the generated class. UPDATE: Add the /namespace parameter to add a namespace to the generated code. "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN\SPMetal" /web:http://YourServer /namespace:MySPMetalNameSpace /code:OutPutFileName.cs /language:csharp /parameters:SPMetal.xml

• Why can't Ubuntu find an ext3 filesystem on my hard-drive?

  - by urig

  This question is related to this question: Not enough components to start the RAID array? I'm trying to retrieve data from a "Western Digital MyBook World Edition (white light)" NAS device. This is basically an embedded Linux box with a 1TB HDD in it formatted in ext3. It stopped booting one day for no apparent reason. I have extracted the HDD from the NAS device and installed it in a desktop machine running Ubuntu 10.10 in the hope of accessing the files on the drive. I have followed instructions in this forum post, intended to mount the drive through Terminal: http://mybookworld.wikidot.com/forum/t-90514/how-to-recover-data-from-wd-my-book-world-edition-nas-device#post-976452 I have identified the partition that I want to mount and recover files from as /dev/sd4 by running "fdisk -l" and getting this: Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0001cf00 Device Boot Start End Blocks Id System /dev/sdb1 5 248 1959930 fd Linux raid autodetect /dev/sdb2 249 280 257040 fd Linux raid autodetect /dev/sdb3 281 403 987997+ fd Linux raid autodetect /dev/sdb4 404 121601 973522935 fd Linux raid autodetect// When I try to mount using: "mount -t ext3 /dev/sdb4 /media/xyz" I get the following error: mount: wrong fs type, bad option, bad superblock on /dev/sdb4, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so And "dmesg | tail" shows me: [ 15.184757] [drm] Initialized nouveau 0.0.16 20090420 for 0000:01:00.0 on minor 0 [ 15.986859] [drm] nouveau 0000:01:00.0: Allocating FIFO number 1 [ 15.988379] [drm] nouveau 0000:01:00.0: nouveau_channel_alloc: initialised FIFO 1 [ 16.353379] EXT4-fs (sda5): re-mounted.

I guess that last line is the punch line :) Why can't it find the ext3 filesystem on my drive? What do I need to do to mount this partition and copy its contents? Does it have anything to do with the drive being part of a RAID Array (see question mentioned above)? Many thanks to any who can help.

• 'Unable to mount Filesystem' Error

  - by Charles

  Trying to extract data from a 'bricked' Western Digital MyBook Live 2tb drive. I came across a forum that advised to use Ubuntu (booted from a CD) on my Macbook. Managed to download and create a boot CD for Ubuntu (like this little operating system btw). Booted the machine with the CD and plugged the drive (which I had extracted from it's casing and placed into a external USB SATA case & plugged to the laptop). The drive is seen by Ubuntu but each time I click on the drive, it gives me the following error: Unable to mount 2.0 TB Filesystem Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb4, missing codepage or helper program, or other error In some cases useful info is found in syslog -try dmesg | tail or so I am new to this and spent quite some time searching this site to see if I could find a solution to this problem without troubling anyone. I came up with a few that came close but some of the questioners mentioned that they had lost data...which scared me from going further. I need to basically extract 1 particular folder from the drive. If I can get to mount this volume 'sdb4', there is a folder called 'My_Work' which I need to back up. The rest I have/had a copy of. When I typed in dmesg | tail...I got several lines..but I think ones that are relevant are: [ 406.864677] EXT4-fs (sdb4): bad block size 65536 [ 429.098776] hfs: write access to a journaled filesystem is not supported, use the force option at your own risk, mounting read-only [ 439.786365] hfs: write access to a journaled filesystem is not supported, use the force option at your own risk, mounting read-only [ 445.982692] EXT4-fs (sdb4): bad block size 65536 [ 1565.841690] EXT4-fs (sdb4): bad block size 65536 I read somewhere to try/check 'sudo fdisk -l /dev/sdb4'. It gave me the following result: Disk /dev/sdb44: 1995.8 GB, 1995774623744 bytes 255 heads, 63 sectors/track, 242639 cylinders, total 3897997312 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/sdb4 doesn't contain a valid partition table This is where I reached and got frustrated and decided to try & get help on this without digging myself deeper into a hole! I understand that the answer may already be out there. If so, could someone please point me in the right direction. And if not, could someone please resolve (if possible) my situation!

• PASS: FY10 Actuals Posted

  - by Bill Graziano

  Earlier this year we published preliminary fiscal year 2010 financials to the Governance page on the PASS web site.  Please remember that FY10 runs from July 1st, 2009 through June 30th, 2010 and includes the November 2009 Summit.  We do our fiscal year this way so that the Summit falls earlier in the fiscal year.  The financials we had posted were P&L numbers at the portfolio level.  Prior to this we had posted our detailed budget but only posted the auditors report at the end of each year.  Today we updated our published financials to include: Pre-audit actuals from FY10 at the same level as our budget.  The document has both actuals and budget for FY10 side by side.  This is over 20 pages of detailed financial information covering hundreds of line-items. A letter describing key differences between our budget and actuals.  I walked through each line item where the difference was greater than $25,000 and explained what happened and why. We updated the financial graph going back to 2003 to include FY10. This update should “close the loop” on our financials.  You can now start with the published budget and compare it to the finished financials at the same level of detail.  We also plan to publish the auditor’s report when that is completed -- as we do every year. Overall I’m very happy with how FY10 turned out.  Keep in mind that this was the November 2009 Summit so we were still facing economic challenges.  With all that we were roughly break-even showing a $15,000 profit on $3.9 million of revenue.  I didn’t find anything shocking in reviewing our actual vs. budget but there were a few things that needed explanation.  You can see those in the letter on the governance page. Please keep in mind that these are the actuals from our operating financials.  The auditor may have us make adjustments for depreciation or other financial transactions.  We may also account for certain transactions differently for tax purposes than we do for financial reporting purposes.  I feel these financial statements give you the clearest picture of how our organization spends its money. We were late publishing these this year.  We were working through some tax issues and that delayed our ability to file our final tax forms which delayed this process.  In hindsight I should have published these documents as soon as we had them and not waited for the tax issues.  We’ll do this better in the future. And on a final note, you don’t need to login to view these documents.  If you have any questions you can post them here.  If we get more than a few questions we may see about creating some forums for financial issues on the PASS web site.

• Screen brightness dull after upgrade to Ubuntu 14.04

  - by user288426

  After upgrading to Ubuntu 14.04 I found that I could not increase screen brightness. I'm using a Samsung NC110 netbook. Initially the function key to modify brightness did not respond at all. After implementation of the first part of the fix, the key came alive and the brightness bar could be modified. Yet at maximum brightness indicated the screen still remained very dull. The 2nd part of the fix cures that problem, at least for this type of machine. First part of the fix was copied and modified in line with my experience from following post: How to control Brightness Open a terminal (Ctrl + Alt + T). Then type sudo nano /etc/default/grub. It will ask for your password. Type it in. Around the 11th line, there will be something like: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash". Change it to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor" Save the file by Ctrl+O followed by Ctrl+X. Then run sudo update-grub in the terminal. Reboot and see if backlight adjustment works. Then I needed to modify the rc.local file. Therefore read below fix to understand the procedure: problem with adjusting brightness Ubuntu 14.04 In my case I had 2 folders listed under /sys/class/backlight which were: intel_backlight samsung I realized that the samsung folder is governing. I had to modify the check for max brightness to: cat /sys/class/backlight/samsung/max_brightness In my case the max value obtained is 8. Besides putting this into rc.local, I also had to uncomment the first line to get this working. My rc.local under /etc/ now looks as follows: !/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. echo 8 > /sys/class/backlight/samsung/brightness exit 0 Now I can modify brightness on my netbook and also can get the screen up to its maximum brightness. Hope this is helpful.

• Collaborative work (small team) - Best practices

  - by LEM01

  I'm currently working in a very small team of programmers (2-3) and I'm looking for advices/best practices on how to organise our work. We're all working on the same application using PHP. Today we're kind of all working on our way. Today situation: List item that have to be worked on by each dev 1/week. What has to be done is defined at a high functional level (ex: Build the search engine for this product..) Commit / merge our individual branches (git) every week before the next meeting No real dev rules, no code review No test written (aouutch) Problems faced: Code quality issue: discovering someone else code is sometime tough (inline, variable+function+class names, spaces, comments..) Changes in already existing classes (impact on someone else work) Responsibility of each dev unclear: after getting someone else code and discover something messy, should I make the change? Should he make the change? How to plan those things,... What I'm looking for: Basically I'm looking into structuring the way we develop things in order to avoid frustration and improve overall quality. How to define coding standards (naming convention, code rules...)? Do you you any validation script to make sure code is valid before committing? Do you think that defining an architect role in the team is needed? Someone that would actually define what has to be developed during the next phase. By defining interfaces or class descriptions that have to be written. (Does it make sense in such a small team?) Today we're losing time into understanding what others did or tried to do, we're also losing time in discussion like "you should have done it that way! Why is this class doing that and not that..? Shouldn't we have a embedded class rather that this set of data...". I'm looking into a work process, maybe with more defined responsibilities and process in order to improve our performance. If you have experience, advices, best practices or anything to share that we could benefit from it will be much appreciated! Thanks a lot for your time!

• Website File and Folder Structure

  - by Drummss

  I am having a problem learning how proper website structure should be. And by that I mean how to code the pages and how folder structure should be. Currently I am navigating around my website using GET variables in PHP when you want go to another page, so I am always loading the index.php file. And I would load the page I wanted like so: $page = "error"; if(isset($_GET["page"]) AND file_exists("pages/".$_GET["page"].".php")) { $page = $_GET["page"]; } elseif(!isset($_GET["page"])) { $page = "home"; } And this: <div id="page"> <?php include("pages/".$page.".php"); ?> </div> The reason I am doing this is because it makes making new pages a lot easier as I don't have to link style sheets and javascript in every file like so: <head> <title> Website Name </title> <link href='http://fonts.googleapis.com/css?family=Lato:300,400' rel='stylesheet' type='text/css'> <link rel="stylesheet" href="css/style.css" type="text/css"> <link rel="shortcut icon" href="favicon.png"/> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js" type="text/javascript"></script> <script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js" type="text/javascript"></script> </head> There is a lot of problems doing it this way as URLs don't look normal ("?page=apanel/app") if I am trying to access a page from inside a folder inside the pages folder to prevent clutter. Obviously this is not the only way to go about it and I can't find the proper way to do it because I'm sure websites don't link style sheets in every file as that would be very bad if you changed a file name or needed to add another file you would have to change it in every file. If anyone could tell me how it is actually done or point me towards a tutorial that would be great. Thanks for your time :)

• How can I cleanly and elegantly handle data and dependancies between classes

  - by Neophyte

  I'm working on 2d topdown game in SFML 2, and need to find an elegant way in which everything will work and fit together. Allow me to explain. I have a number of classes that inherit from an abstract base that provides a draw method and an update method to all the classes. In the game loop, I call update and then draw on each class, I imagine this is a pretty common approach. I have classes for tiles, collisions, the player and a resource manager that contains all the tiles/images/textures. Due to the way input works in SFML I decided to have each class handle input (if required) in its update call. Up until now I have been passing in dependencies as needed, for example, in the player class when a movement key is pressed, I call a method on the collision class to check if the position the player wants to move to will be a collision, and only move the player if there is no collision. This works fine for the most part, but I believe it can be done better, I'm just not sure how. I now have more complex things I need to implement, eg: a player is able to walk up to an object on the ground, press a key to pick it up/loot it and it will then show up in inventory. This means that a few things need to happen: Check if the player is in range of a lootable item on keypress, else do not proceed. Find the item. Update the sprite texture on the item from its default texture to a "looted" texture. Update the collision for the item: it might have changed shape or been removed completely. Inventory needs to be updated with the added item. How do I make everything communicate? With my current system I will end up with my classes going out of scope, and method calls to each other all over the place. I could tie up all the classes in one big manager and give each one a reference to the parent manager class, but this seems only slightly better. Any help/advice would be greatly appreciated! If anything is unclear, I'm happy to expand on things.

• WCF Routing Service Filter Generator

  - by Michael Stephenson

  Recently I've been working with the WCF routing service and in our case we were simply routing based on the SOAP Action. This is a pretty good approach for a standard redirection of the message when all messages matching a SOAP Action will go to the same endpoint. Using the SOAP Action also lets you be specific about which methods you expose via the router. One of the things which was a pain was the number of routing rules I needed to create because we were routing for a lot of different methods. I could have explored the option of using a regular expression to match the message to its routing but I wanted to be very specific about what's routed and not risk exposing methods I shouldn't via the router. I decided to put together a little spreadsheet so that I can generate part of the configuration I would need to put in the configuration file rather than have to type this by hand. To show how this works download the spreadsheet from the following url: https://s3.amazonaws.com/CSCBlogSamples/WCF+Routing+Generator.xlsx In the spreadsheet you will see that the squares in green are the ones which you need to amend. In the below picture you can see that you specify a prefix and suffix for the filter name. The core namespace from the web service your generating routing rules for and the WCF endpoint name which you want to route to. In column A you will see the green cells where you add the list of method names which you want to include routing rules for. The spreadsheet will workout what the full SOAP Action would be then the name you will use for that filter in your WCF Routing filters. In column D the spreadsheet will have generated the XML snippet which you can add to the routing filters section in your configuration file. In column E the spreadsheet will have created the XML snippet which you can add to the routing table to send messages matching each filter to the appropriate WCF client endpoint to forward the message to the required destination. Hopefully you can see that with this spreadsheet it would be very easy to produce accurate XML for the WCF Routing configuration if you had a large number of routing rules. If you had additional methods in other services you can simply copy the worksheet and add multiple copies to the Excel workbook. One worksheet per service would work well.

• Frame rate on one of two machines running same code seems to be capped at 60 for no reason

  - by dennmat

  ISSUE I recently moved a project from my laptop to my desktop(machine info below). On my laptop the exact same code displays the fps(and ms/f) correctly. On my desktop it does not. What I mean by this is on the laptop it will display 300 fps(for example) where on my desktop it will show only up to 60. If I add 100 objects to the game on the laptop I'll see my frame rate drop accordingly; the same test on the desktop results in no change and the frames stay at 60. It takes a lot(~300) entities before I'll see a frame drop on the desktop, then it will descend. It seems as though its "theoretical" frames would be 400 or 500 but will never actually get to that and only do 60 until there's too much to handle at 60. This 60 frame cap is coming from no where. I'm not doing any frame limiting myself. It seems like something external is limiting my loop iterations on the desktop, but for the last couple days I've been scratching my head trying to figure out how to debug this. SETUPS Desktop: Visual Studio Express 2012 Windows 7 Ultimate 64-bit Laptop: Visual Studio Express 2010 Windows 7 Ultimate 64-bit The libraries(allegro, box2d) are the same versions on both setups. CODE Main Loop: while(!abort) { frameTime = al_get_time(); if (frameTime - lastTime >= 1.0) { lastFps = fps/(frameTime - lastTime); lastTime = frameTime; avgMspf = cumMspf/fps; cumMspf = 0.0; fps = 0; } /** DRAWING/UPDATE CODE **/ fps++; cumMspf += al_get_time() - frameTime; } Note: There is no blocking code in the loop at any point. Where I'm at My understanding of al_get_time() is that it can return different resolutions depending on the system. However the resolution is never worse than seconds, and the double is represented as [seconds].[finer-resolution] and seeing as I'm only checking for a whole second al_get_time() shouldn't be responsible. My project settings and compiler options are the same. And I promise its the same code on both machines. My googling really didn't help me much, and although technically it's not that big of a deal. I'd really like to figure this out or perhaps have it explained, whichever comes first. Even just an idea of how to go about figuring out possible causes, because I'm out of ideas. Any help at all is greatly appreciated.

• How to use multiple search keys?

  - by user32565

  I have a database wherein the files are named abcd100.00b, abcd101.00b, etc. I need a code where when the user enters abcd separate then 100 to 110, all the files with the name abcd and in the range 100 to 110 should get displayed now the following code can display only the first four characters. How do I implement this? <?php //capture search term and remove spaces at its both ends if the is any $searchTerm = trim($_GET['keyname']) ; //check whether the name parsed is empty if($searchTerm == "rinex_file") { echo "Enter name you are searching for."; exit(); } if($searchTerm == "rinex_file") { echo "Enter name you are searching for."; exit(); } //database connection info $host = "localhost"; //server $db = "rinex"; //database name $user = "m"; //dabases user name $pwd = "c"; //password //connecting to server and creating link to database $link = mysqli_connect($host, $user, $pwd, $db); //MYSQL search statement $query = "SELECT * FROM rinexo WHERE rinex_file LIKE '%$searchTerm%'"; $results = mysqli_query($link, $query) ; /* check whethere there were matching records in the table by counting the number of results returned */ if(mysqli_num_rows($results) >= 1){ echo '<table border="1"> <tr> <th>rinex version</th> <th>program</th> <th>date</th> <th>maker name</th> <th>maker number</th> <th>observer</th> <th>agency</th> <th>position_X_Y_Z</th> </tr>'; while($row = mysqli_fetch_array($results)){ echo '<tr> <td>'.$row['rinex_version'].'</td> <td>'.$row['pgm'].'</td> <td>'.$row['date'].'</td> <td>'.$row['marker_name'].'</td> <td>'.$row['marker_no'].'</td> <td>'.$row['observer'].'</td> <td>'.$row['agency'].'</td> <td>'.$row['position_X_Y_Z'].'</td> </tr>'; } echo '</table>'; }else{ echo "There was no matching record for the name " . $searchTerm; }

• Could I be going crazy with Event Handlers? Am I going the "wrong way" with my design?

  - by sensae

  I guess I've decided that I really like event handlers. I may be suffering a bit from analysis paralysis, but I'm concerned about making my design unwieldy or running into some other unforeseen consequence to my design decisions. My game engine currently does basic sprite-based rendering with a panning overhead camera. My design looks a bit like this: SceneHandler Contains a list of classes that implement the SceneListener interface (currently only Sprites). Calls render() once per tick, and sends onCameraUpdate(); messages to SceneListeners. InputHandler Polls the input once per tick, and sends a simple "onKeyPressed" message to InputListeners. I have a Camera InputListener which holds a SceneHandler instance and triggers updateCamera(); events based on what the input is. AgentHandler Calls default actions on any Agents (AI) once per tick, and will check a stack for any new events that are registered, dispatching them to specific Agents as needed. So I have basic sprite objects that can move around a scene and use rudimentary steering behaviors to travel. I've gotten onto collision detection, and this is where I'm not sure the direction my design is going is good. Is it a good practice to have many, small event handlers? I imagine going the way I am that I'd have to implement some kind of CollisionHandler. Would I be better off with a more consolidated EntityHandler which handles AI, collision updates, and other entity interactions in one class? Or will I be fine just implementing many different event handling subsystems which pass messages to each other based on what kind of event it is? Should I write an EntityHandler which is simply responsible for coordinating all these sub event handlers? I realize in some cases, such as my InputHandler and SceneHandler, those are very specific types of events. A large portion of my game code won't care about input, and a large portion won't care about updates that happen purely in the rendering of the scene. Thus I feel my isolation of those systems is justified. However, I'm asking this question specifically approaching game logic type events.

• NVIDIA Additional Drivers Empty - maximum resolution 640x480 - Driver disappears

  - by Hannibal

  EDIT: Optimus card. For resolution please read this thread: "You do not appear to be using the nvidia x server"(screenshot included) And this: Ubuntu 11.10 problem with Nvidia Thanks! I know, I know yet another NVIDIA question. So I did all the research. I uninstalled and installed nvidia-settings and drivers and nvidia-current from PPE repositories which are the most updated ones. I executed nvidia-xconfig. I have two major problems. One: Additional Drivers setting is empty! It doesn't contain any driver although one is installed. I have executed apt-get update too. But still the list is empty. Two: If I execute nvidia-xconfig it will properly configure an xorg.conf file. I restart but the maximum resolution I got is 640x480. I tried the xrandr but I can't add any resolution to display LVDS1. Some weird error occurs. So I can't add a proprietary driver and I can't boot in with the xorg file created by Nvidia... What can I do? With some work ( unistall nvidia-current and install libgl1-mesa-glx I was able to activate some kind of usage of my card because the resolution got better... and I added bumbelbee to because I have multiple video cards... ) but still the list is empty. I don't know what to do at this point??!!! Also: this is the most important part. When I first installed my ubuntu yesterday 11.10 one I saw the driver!! The driver was there... And then I ofc updated every package from internet.. And after that it was gone. And I can't bring it back. So there must be something wrong with one of the updates. But which???? Thanks for any extra info you can provide! I'm really desperate to solve this issue.

• Sampling SQL server batch activity

  - by extended_events

  Recently I was troubleshooting a performance issue on an internal tracking workload and needed to collect some very low level events over a period of 3-4 hours.  During analysis of the data I found that a common pattern I was using was to find a batch with a duration that was longer than average and follow all the events it produced.  This pattern got me thinking that I was discarding a substantial amount of event data that had been collected, and that it would be great to be able to reduce the collection overhead on the server if I could still get all activity from some batches. In the past I’ve used a sampling technique based on the counter predicate to build a baseline of overall activity (see Mikes post here).  This isn’t exactly what I want though as there would certainly be events from a particular batch that wouldn’t pass the predicate.  What I need is a way to identify streams of work and select say one in ten of them to watch, and sql server provides just such a mechanism: session_id.  Session_id is a server assigned integer that is bound to a connection at login and lasts until logout.  So by combining the session_id predicate source and the divides_by_uint64 predicate comparator we can limit collection, and still get all the events in batches for investigation. CREATE EVENT SESSION session_10_percent ON SERVER ADD EVENT sqlserver.sql_statement_starting(     WHERE (package0.divides_by_uint64(sqlserver.session_id,10))), ADD EVENT sqlos.wait_info (        WHERE (package0.divides_by_uint64(sqlserver.session_id,10))), ADD EVENT sqlos.wait_info_external (        WHERE (package0.divides_by_uint64(sqlserver.session_id,10))), ADD EVENT sqlserver.sql_statement_completed(     WHERE (package0.divides_by_uint64(sqlserver.session_id,10))) ADD TARGET ring_buffer WITH (MAX_DISPATCH_LATENCY=30 SECONDS,TRACK_CAUSALITY=ON) GO   There we go; event collection is reduced while still providing enough information to find the root of the problem.  By the way the performance issue turned out to be an IO issue, and the session definition above was more than enough to show long waits on PAGEIOLATCH*.

• Office lights on or off in programming department? How to decide? [closed]

  - by smp7d

  At my company, the programmers who sit in the same area are constantly fighting over whether the lights stay on or off. Because there is no official policy it makes it a particularly sticky situation. We are a typical cube-farm and we have those typical cube-farm fluorescent lights and smaller ones at our desks. With the lights off, it is difficult to read and you would probably need to turn on your desk light (which some people do anyway). All programmers in our department do most of their reading on their monitor because of the nature of our business. Some feel that we should have a vote to decide whether the lights stay on or off. A couple who prefer 'lights on' feel that the vote would need to be unanimous to turn them off as having them on is the more natural office setting. Those who want them off point out that all other departments keep their lights off. I have heard all of the arguments: -Fluorescent lights cause eye strain -Reading in dark causes eye strain -The desk lights can be used if light is needed -People from other departments feel uncomfortable approaching us in the "dark" -The monitors are harder to see in the light ... Right now, some of the developers turn off the lights and some turn them on. It really just depends who last walked by the switch. I am a bit sick of the controversy as it feels a bit childish at the moment. I'm tired of hearing about it and I'm tired of having to talk about it. I tried to help them decide but as I explained, voting wasn't enough. Do other programming departments have this same argument? What is the standard or traditionally accepted option in a programming area? Are there any good reasons for one way or the other outside of preference? How can we decide fairly? EDIT Just a little more info... We do not have clients/visitors come into our office. We do have windows and hall lights that make our environment plenty bearable with the lights off. It kind of resembles a meeting room that has the lights off during a powerpoint presentation.

• [EF + Oracle] Inserting Data (1/2)

  - by JTorrecilla

  Prologue Following EF series (I ,II y III) in this chapter we will see how to create DB record from EF. Inserting Data Like we indicated in the 2º post: “One Entity matches with a DB record, and one property match with a Table Column”. To start, we need to create an object from one of the Entities: 1: EMPLEADOS empleado = new EMPLEADOS(); Also like, I told previously, Exists the possibility to use the Static Function defined by VS for each Entity: Once we have created the object, we can Access to it properties to fill like a common class:   1: empleado.NOMBRE = "Javier Torrecilla";   After finish of fill our Entity properties, it must be needed to add the object to the appropriate ObjectSet in the ObjectContext: 1: enti.EMPLEADOS.AddObject(empleado); or 1: enti.AddToEMPLEADOS(empleado); Both methods will do the same action, create an insert statement. Have we finished? No. Any Entity has a property called “EntityState”. This prop is an Enum from “EntityState”, which has the following: Detached: the Entity is created, but not added to the Context. Unchanged: There is no pending changes in the Entity. Added: The entity is added to the ObjectSet, but it is not yet sent to the DB. Deleted: The object is deleted form the ObjectSet, but not yet from the DB. Modified: There is Pending Changes to confirm. Let’s see, the several values of the property during the Creation steps: 1. While the Object is created and we are filling the props: EntityState.Detached; 2. After adding to the ObjectSet: EntityState.Added. This not indicated that the record is in the DB 3. Saving the Data: To sabe the data in the DB, we are going to call “SaveChanges” method of the Object Context. After invoke it, the property will be EntityState.Unchanged.   What does SaveChanges Method? This function will synchronize and send all pending changes to DB. It will add, modify or delete all Entities, whose EntityState property, is setted to Added, Deleted or Modified. After finishing, all added or modified entities will be change the State to “Unchanged”, and deleted Entities must take the “Detached” state.

• Can Anything be Done to Make Improv (a 1993 Win 3.1 App) handle larger Files?

  - by user75185

  My very favorite spradsheet is Improv, a 1993 Windows 3.1 application. It still puts Excel to shame for building spreadsheets and writing formulas. The only problem is because Improv was written when 1 Meg of RAM was state of the art, it becomes unstable when working with larger spreadsheets and often crashes and/or corrupts the data file. I am working on a project that greatly exceeds Improv's limits. Although it will ultimately require more robust databasing capability, I could save a lot of critical time if I could delay that headache and continue working in Improv for now. To that end, I moved to the only product I could find that comes close, Quantrix, which is nothing more than Improv updated to handle large spreadsheets and utilize today's technologies. The problems with Quantrix are its speed (significantly slower than Improv) and its $1000 price (which I cannot afford). I have already had 3 15 day extensions after the initial 30 day trial, so my time to use Quantrix as a bridge is at its end. Searches for Improv over the years have gotten me nowhere and, not surprisingly after reading some posts on this site, I got nothing for the money and time invested to find a programmer to write code to "fix" this problem. Improv is freely available as "abandonware" at http://vetusware.com/download/LotusImprov2.1/?id=5797 , and the best background info can be found on Wikipedia and at "Moose's Greatest Software Products of All Time - Lotus Improv" http://moosevalley.fhost.com.au/mooses_review_page_lotus_improv.html It is critically urgent for me to focus on analyzing the data asap. Working in a stable Improv would, without question, be the fastest route. To that end, I am looking for answers to the following questions and anything else that might be helpful: 1) Is it lawful to hire someone to fix Improv for my own use? If so, 2) About how much should it cost? 3) About how long should it take? 4) What skills should I be looking for &/or how should a post be worded? 5) Is there a niche site where it should it be posted? 6) What questions can I ask to quickly screen candidates? Since I am not a programmer, I need questions the answers to which leave no room to confuse me, whether intentional or not. For example, what tools or players should someone with an acceptable competency level have knowledge of?

• Developing web sites that imitate desktop apps. How to fight that paradigm? [closed]

  - by user1598390

  Supposse there's a company where web sites/apps are designed to resemble desktop apps. They struggle to add: Splash screens Drop-down menus Tab-pages Pages that don't grow downward with content, context is inside scrollable area so page is of a fixed size, as if resembling the one-screen limitation of desktop apps. Modal windows, pop-ups, etc. Tree views Absolutely no access to content unless you login-first, even with non-sensitive content. After splash screen desapears, you are presented with a login screen. No links - just simulated buttons. Fixed page-size. Cannot open a linked in other tab Print button that prints directly ( not showing printable page so the user can't print via the browser's print command ) Progress bars for loading content even when the browser indicates it with its own animation Fonts and color amulate a desktop app made with Visual Basic, PowerBuilder etc. Every app seems almost as if were made in Visual Basic. They reject this elements: Breadcrumbs Good old underlined links Generated/dynamic navigation, usage-based suggestions Ability to open links in multiple tabs Pagination Printable pages Ability to produce a URL you can save or share that links to an item, like when you send someone the link to an especific StackExchange question. The only URL is the main one. Back button To achieve this, tons of javascript code is needed. Lots and lots of Javascript and Ajax code for things not related with the business but with the necessity to hide/show that button, refresh this listbox, grey-out that label, etc. The coplexity generated by forcing one paradigm into another means most lines of code are dedicated to maintain the illusion of a desktop app. What is the best way to change this mindset, and make them embrace the web, and start producing modern, web apps instead of desktop imitations ? EDIT: These sites are intranet sites. Users hate these apps. They constantly whine about them, but they have to use them to do their daily work. These sites are in-house solutions, the end-users have no choice but to use them. They are a "captive audience". Also, substitution will not happen because of high costs. But at least if that mindset is changed, new developments would be more web-like.

• How does the fstab 'defaults' option work? Is relatime recommended?

  - by hushs

  I know the fstab defaults option means this: rw,suid,dev,exec,auto,nouser,async. But what if I want to add one more option, for example relatime, should I still add defaults too or they are applied anyway? Is it needed to add at least one option? Some examples: 1. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 defaults 0 2 2. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 0 2 3. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 defaults,relatime 0 2 4. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 relatime 0 2 Is the (2) correct(no option at all)? Are the (1) and (2) the same? Are the (3) and (4) the same? Furthermore, I read in the Ubuntu Community Documentation that in Ubuntu 8.04 relatime was used as default for linux native file systems. Is it still true for 12.04? If yes, then why do I see this if I use the mount command: /dev/sda2 on / type ext4 (rw,errors=remount-ro) If no, why not? It isn't recommended to use relatime now? I just wanted to apply it to my non system partitions, it is a good idea? EDIT: I found an other command to list the mounted partitions and their options: cat /proc/mounts This is the result of a partition mounted with the defaults option in fstab: /dev/sdb2 /media/adat ext3 rw,relatime,errors=continue,barrier=1,data=ordered 0 0 This is the output of mount for the same partition: /dev/sdb2 on /media/adat type ext3 (rw) And here is both result if the same partition mounted from Nautilus as a non-root user: /dev/sdb2 /media/adat ext3 rw,nosuid,nodev,relatime,errors=continue,barrier=1,data=ordered 0 0 /dev/sdb2 on /media/adat type ext3 (rw,nosuid,nodev,uhelper=udisks) So it looks like relatime is used if we mount an ext partition in 12.04. So it is unneeded to add it manually. So my problem is broadly solved. But I still can't see why the options that should be in the defaults are not listed even with the cat /proc/mounts. Maybe there is a third and even better method to list the partition mount options :)

• what would be a good way to implement/render a 2d tiled map for a browser game?

  - by jj_

  I've made this little rpg ruby game I did while learning and now I'd like to make it into a browser game. I've already set up Sinatra framework to serve it, so what I am looking for, before everything else, is a way to represent the game map in browser (location attributes are stored in db). A new map is randomly generated by code for each new game at each game start. For now forget db, and let's say a map (say 100x100 "squares") is stored as a tridimensional array. (x,y, ...) Last "dimension" of array stores who & what is at that map cell: a player, a building, whatever. So all I have to do is render those "squares" or array cells to a 2d tiled map in the browser. The map does not need to refresh or be dynamically fetched as you scroll it, (at least at this stage of development) but, a technology which would allow me to do so in future would be a good reason for choosing it. Things that I thought of: html tables, html5 canvas, some js framework which is designed exactly with this purpose (which I do not know of = please advice). Yes I know about gamequery-js framework, but I've never used it, and I don't know if it's going to slow down everything down to inusability as I'm adding new features (scrolling, ajax). I really don't know of any other alternatives.. maybe there are lighter approaches? Easier or more minimalistic ways ? More targeted js framework which is the right tool for the job? Maybe just some html canvas code, or even simple image maps, or images with absolute positioning will be enough? The thing is I'd like to start simple, and then gradually make it better, so, as I said before, I'd prefer something that will give me room for improvement or is headed toward new web tendencies but which will also give me a bit of gratification in the beginning :) So.. advices are needed! And appreciated! :) Thanks p.s. Flash is excluded because I don't like it.
