• WINEHQ - wine_gecko won't init - HTML Rendering disabled

  - by Nick

  Hello Super Users, I'm currently trying to get a windows compiled program to work through Wine to run on Linux and MacOSX. When I run the program through wine, it prompts me to install Gecko which I do. Later on in the program, it attempts to use MSHTML to render HTML but I get these error messages on my console instead. err:mshtml:init_xpcom NS_InitXPCOM2 failed: 80004005 err:mshtml:HTMLDocument_Create Failed to init Gecko, returning CLASS_E_CLASSNOTAVAILABLE fixme:ole:CoCreateInstance no instance created for interface {00000000-0000-0000-c000-000000000046} of class {25336920-03f9-11cf-8fd0-00aa00686f13}, hres is 0x80040111 I'm using Wine 1.1.34 and a similar bug was supposedly fixed in 1.1.33 http://bugs.winehq.org/show_bug.cgi?id=12578 I've been at this all afternoon, is there anything I'm missing? Thanks, Nick

• Realtek HD Audio playing weird with certain video formats

  - by dyasny

  Hi, I have a Gigabyte motherboard with an onboard Realtek HD sound card. The card is working perfectly everywhere, except for a single video format, where the voice is distorted, sounds as if it's been passed through a metal tube. Been googling for this, but couldn't find an answer anywhere. The movie plays fine on other systems (got Linux everywhere else), but on this one (winXP-x64-sp2) it just doesn't. Here are some details: MPC: Type: KLCP WMV File Audio: 0x000a 22050Hz mono 20Kbps [Raw Audio 0] Video: Windows Media Video 9 400x300 29.97fps 227Kbps [Raw Video 1] VLC: Codec: wmas Sample rate: 22050 Bits per sample: 16 Bitrate: 20kb/s

• VIM autocompletion: Making ^X^U expand to longest match

  - by Sarah

  I'm using eclim to bring some eclipse functionality to VIM, however the code completion functions seem to work less than ideal. When I press ctrl+x ctrl+u after, for instance, System.out. with the curser right after the last dot, I get the completion popup-menu. This menu is really rather cumbersome to use, and the functionality that I would ideally want is something like: ctrl+x ctrl+u (expands to longest match) fill in more characters (expand to longest match). Is this possible somehow? I've tried fiddling with the completeopts settings, but they don't seem to do what I want.

• Best practice with pyGTK and Builder XML files

  - by Phoenix87

  I usually design GUI with Glade, thus producing a series of Builder XML files (one such file for each application window). Now my idea is to define a class, e.g. MainWindow, that inherits from gtk.Window and that implements all the signal handlers for the application main window. The problem is that when I retrieve the main window from the containing XML file, it is returned as a gtk.Window instance. The solution I have adopted so far is the following: I have defined a class "Window" in the following way class Window(): def __init__(self, win_name): builder = gtk.Builder() self.builder = builder builder.add_from_file("%s.glade" % win_name) self.window = builder.get_object(win_name) builder.connect_signals(self) def run(self): return self.window.run() def show_all(self): return self.window.show_all() def destroy(self): return self.window.destroy() def child(self, name): return self.builder.get_object(name) In the actual application code I have then defined a new class, say MainWindow, that inherits frow Window, and that looks like class Main(Window): def __init__(self): Window.__init__(self, "main") ### Signal handlers ##################################################### def on_mnu_file_quit_activated(self, widget, data = None): ... The string "main" refers to the main window, called "main", which resides into the XML Builder file "main.glade" (this is a sort of convention I decided to adopt). So the question is: how can I inherit from gtk.Window directly, by defining, say, the class Foo(gtk.Window), and recast the return value of builder.get_object(win_name) to Foo?

• Which databases support parallel processing across multiple servers?

  - by David

  I need a database engine that can utilize multiple servers for processing a single SQL query in parallel. So far I know that this is possible with the some engines, though none of them are feasible for me either because of pricing or missing features. The engines currently known to me are: MS SQL (enterprise) DB2 (enterprise) Oracle (enterprise) GridSQL Greenplum Which other engines have this feature? Do you have any experience with using this feature? Edit: I have now proposed a method for creating one myself. Any input is welcome. Edit: I have found another one: Informix Extended Parallel Server

• Rendering a big game universe - bitmaps or vector graphics?

  - by user1641923

  I am new to an Android development, though I have much experience with Java, C++, PHP programming and a bit experience with vector graphics too (basic 3d Studio Max, Flash, etc). I am starting to work on an Android game. It is going to be a 2D space shooter/RPG, and I am not going to use any game engines and any 3D party libs. I really want to create a very large game universe, or even pseudo-infinite (without visible borders, as if it were a 2D projection of a sphere). It should include 10-12 clusters of 7-8 planets/other space objects and random amount of single asteroids/comets, which player can interact with and also not interactive background. I am looking for a least complicated aproach to create such a universe. My current ideas are: Simply create bitmaps with space scenery background so that they can be tiled seamlessly repeated and construct my 2D universe of this tiles, then place interactive objects (planets, other spaceships) on it. Using vector graphics. I would have a solid color background, some random background objects and gradients here and there. My problems here: Lack of knowledge of how well vector graphics is integrated in Android. Performance? Memory usage? Does Android manage big bitmaps well? Do all of the bitmaps have to be in memory during all game process? I am interested in technical details regarding each of the ideas and a suggestion, which I should go with.

• can I force server to always use turboboost?

  - by javapowered

  I'm using HP DL360p Gen8 with 2 * Xeon E5-2640. I do not load CPU 100%, i load it only ~10% and so I guess turboboost is not activated. However I'm using my server for trading so I absolutely don't care about CPU loading but I always want to process my data asap. So I want server to operate using maximum 3 GHz. I.e. 90% of CPU time I don't have anything to process. 10% of CPU time I have data to process. But I need to process it ASAP. I need every single microsecond. So I want server to operate always at maximum "turboboosted" mode. Is it possible?

• What is recommended minimum object size for gzip benefits?

  - by utt73

  I'm working on improving page speed display times, and one of the methods is to gzip content from the webserver. Google recommends: Note that gzipping is only beneficial for larger resources. Due to the overhead and latency of compression and decompression, you should only gzip files above a certain size threshold; we recommend a minimum range between 150 and 1000 bytes. Gzipping files below 150 bytes can actually make them larger. We serve our content through Akamai, using their network for a proxy and CDN. What they've told me: Following up on your question regarding what is the minimum size Akamai will compress the requested object when sending it to the end user: The minimum size is 860 bytes. My reply: What is the reason(s) for why Akamai's minimum size is 860 bytes? And why, for example, is this not the case for files Akamai serves for facebook? (see below) Google recommends to gzip more agressively. And that seems appropriate on our site where the most frequent hits, by far, are AJAX calls that are <860 bytes. Akamai's response: The reasons 860 bytes is the minimum size for compression is twofold: (1) The overhead of compressing an object under 860 bytes outweighs performance gain. (2) Objects under 860 bytes can be transmitted via a single packet anyway, so there isn't a compelling reason to compress them. So I'm here for some fact checking. Is the 860 byte limit due to packet size the end of this reasoning? Why would high traffic sites push this lower/closer to the 150 byte limit... just to save on bandwidth costs, or is there a performance gain in doing so?

• Mapping dynamic buffers in Direct3D11 in Windows Store apps

  - by Donnie

  I'm trying to make instanced geometry in Direct3D11, and the ID3D11DeviceContext1->Map() call is failing with the very helpful error of "Invalid Parameter" when I'm attempting to update the instance buffer. The buffer is declared as a member variable: Microsoft::WRL::ComPtr<ID3D11Buffer> m_instanceBuffer; Then I create it (which succeeds): D3D11_BUFFER_DESC instanceDesc; ZeroMemory(&instanceDesc, sizeof(D3D11_BUFFER_DESC)); instanceDesc.Usage = D3D11_USAGE_DYNAMIC; instanceDesc.ByteWidth = sizeof(InstanceData) * MAX_INSTANCE_COUNT; instanceDesc.BindFlags = D3D11_BIND_VERTEX_BUFFER; instanceDesc.CPUAccessFlags = D3D11_CPU_ACCESS_WRITE; instanceDesc.MiscFlags = 0; instanceDesc.StructureByteStride = 0; DX::ThrowIfFailed(d3dDevice->CreateBuffer(&instanceDesc, NULL, &m_instanceBuffer)); However, when I try to map it: D3D11_MAPPED_SUBRESOURCE inst; DX::ThrowIfFailed(d3dContext->Map(m_instanceBuffer.Get(), 0, D3D11_MAP_WRITE, 0, &inst)); The map call fails with E_INVALIDARG. Nothing is NULL incorrectly, and this being one of my first D3D apps I'm currently stumped on what to do next to track it down. I'm thinking I must be creating the buffer incorrectly, but I can't see how. Any input would be appreciated.

• Split DC role from existing Exchange 2007 server

  - by Graeme Donaldson

  We currently have a single Exchange 2007 Server on Windows Server 2008. It's also a DC and I'd like to split the DC role to a different box. Is this doable without migrating the mailboxes off to a temporary box, re-installing and migrating back? I.e. can I just demote the server without breaking Exchange completely? I know this was quite painful with Server 2003/Exchange 2003, so I'm trying to get an idea of how much different the process is for Server 2008/Exchange 2007.

• Can't get any SMART or temperature data from HDDs

  - by Regs

  I have a PC with recently installed Gigabyte GA-X79-UD5 MB. I've encountered some weird problem with getting SMART data or temperature for HDDs. Every single tool I've tried in Windows 7 just can't get any data (HDTune, AIDA64...). I was suspecting that SMART feature is disabled in BIOS but it's seems like there is no such option in BIOS settings. I've even tried to update BIOS but still no luck. Same issue with both controllers on that MB (Intel and Marvell). It seems unlikely that both controllers end up with exact same issue. Both controllers are working in AHCI mode. Is there anythig that can interfere with getting SMART ant temp data from HDDs? Or is there any way to check that it's actuall MB issue? Is it even possible that it is hardware issue since all HDDs seems to work normal despite the fact that I can't get any temperature or SMART data from it.

• LCD monitor reports incorrect maximum resolution

  - by SLaks

  I have four 20" Planar 2010M LCD monitors with a maximum resolution of 1600 x 1200 connected to two nVidia video cards (8600 GT and 7600 GS). I'm running Windows Server 2003 x86. Recently, two of the monitors have started mis-reporting their maximum resolution as 1280 x 1024. When this first happened, I used nVidia's Custom Resolutions feature to force the monitors back to 1600 x 1200. Yesterday, however, I upgraded nVidia's video card driver, and ever since, I cannot get the DVI one back to 1600 x 1200. When I add the custom resolution in nVidia's control panel, if I set either the width or the height to even a single pixel more than 1280 x 1024, nothing changes when I click Test (the monitor doesn't even flash black, although after 15 seconds, it flashes black and doesn't change). After adding Does anyone know what the problem is? Is there anything I can do about it?

• Foreach loop with 2d array of objects

  - by Jacob Millward

  I'm using a 2D array of objects to store data about tiles, or "blocks" in my gameworld. I initialise the array, fill it with data and then attempt to invoke the draw method of each object. foreach (Block block in blockList) { block.Draw(spriteBatch); } I end up with an exception being thrown "Object reference is not set to an instance of an object". What have I done wrong? EDIT: This is the code used to define the array Block[,] blockList; Then blockList = new Block[screenRectangle.Width, screenRectangle.Height]; // Fill with dummy data for (int x = 0; x <= screenRectangle.Width / texture.Width; x++) { for (int y = 0; y <= screenRectangle.Height / texture.Width; y++) { if (y >= screenRectangle.Height / (texture.Width*2)) { blockList[x, y] = new Block(1, new Rectangle(x * 16, y * 16, texture.Width, texture.Height), texture); } else { blockList[x, y] = new Block(0, new Rectangle(x * 16, y * 16, texture.Width, texture.Height), texture); } } }

• How Can I assign an IP address to my virtual Windows Server, so that I can start using it almost as a VPS?

  - by Nelson Symonds

  We are a small office set up with two PC's out of which one of my PCs runs 24hrs. Its almost equivalent to a small server, but right now we're in need of a server which is why I am planning to keep my machine as well as a server into a single PC. I've used VMware Workstation to create a powerful Windows Server 2008 within my PC and I want to attach it to my Network Switch through the same PC where I am hosting it. I want to use it almost like a physical server with an IP address and everything so that I can connect from one Pc to the Server directly or my applications can connect to Server straight with the IP address. How should I do this? Step by step instructions would be appreciated. Thanks in Advance, Best regards Nelson

• GlassFish Extension for Oracle JDeveloper

  - by Shay Shmeltzer

  We just release a new version of Oracle JDeveloper - 11.1.2.3. One new feature here is built-in support for GlassFish. This include the ability to create an "application server" connection to GlassFish and then deploy to that server with one click from inside JDeveloper. You can use this for deploying Oracle ADF Essentials application on Glassfish, but you can also use it to deploy any Java EE application you build in JDeveloper on GlassFish. However, if you are planning to work with GlassFish and JDeveloper on a more regular basis as your development server, then you might find my new extension useful. The new extension allows you to start and stop an external GlassFish instance, as well as start it in debug mode (which will allow JDeveloper to remotely debug your application as it runs on the server. I also added a button that will invoke the web admin console of Glassfish. Here is a quick demo that will show you how to work with the extension: The extension is available from help->check for updates, or you can download it directly from here, and then use help->check for updates pointing to the local zip file.

• Internet Explorer 10 auto-correct randomly capitalises words

  - by Andreas Rejbrand

  I use Internet Explorer 10 on my Windows 7 laptop (because the fingerprint browser add-on only works in IE). I have noticed that IE 10 has a built-in spellchecker, which is great. Now, I write about 90 % English and 10 % Swedish on web sites, so it is somewhat unfortunate that it isn't possible to change the spell-checker language 'on-the-fly'. But that's a minor issue. The main problem is that, when I write English comments, the spell-checker (apparently randomly) capitalises some Words. For instance, the 'words' of the previous sentence was changed automatically to 'Words'. Another Word that is Always capitalised is Before. (Yes, the Three Words that are incorrectly capitalised in the previous sentence are due to the auto-correct 'feature', and apparently 'three' is also a problematic word.) Is this really something that happens to every (bilingual) user? Is there any way to fix the issue (preferably without disabling the spell-checker altogether)?

• Storing data for use on Android and Windows Applications

  - by Andy Mepham

  I posted this last night on StackOverflow and was advised to move it over to StackExchange, thank you for taking a moment to look at my question. I'm developing a project proposal for my final year project at University and as I aim to use programming languages I am currently not too familiar with I'm looking for some guidance - I can't include details of my project but hopefully you will understand what I'm after. I'm going to be creating an Android application (in Java) and a Windows Application (in C#) that will ideally access, query and update a remotely hosted Database or set of XML files (this would most likely be over the Internet). I've done some looking around the internet and SQLite seems like a safe-bet for cross-platform manipulation of the database; however I would like to keep the system as lightweight as possible and I'm wondering whether XML files may provide a better alternative? Anyone out there that has experience using SQLite and/or remotely hosted XML for the purposes of Android and/or C# development that could point me in the right direction? If there is an alternative solution other than those I have mentioned I would be interested to hear about them too. Thank you for taking the time to read my question. Edit: The purpose of this application is for a small scale business, the data source would not need to be updated by more than one source but may be view from multiple sources (i.e. through multiple phones and a desktop PC). The database wouldn't be updating masses of data at a time (most likely single rows of a few tables at the most).

• Virus blocking incoming connections ?

  - by Benoît

  Hello, on my windows 2003 server, all incoming connections are dropped. I can see them getting in using Wireshark, but even a single ping from another computer fails. All locally initiated connection work fine (i'm asking from the server). This server is the DC/DHCP/DNS/File server, so computer clients are in the dark. I've run varius antivirus and removal tools without any luck. The Windows Firewall is disabled. I'm wild-guessing at some virus/worm. How can i check why these incoming ICMP/TCP SYN/etc are dropped ? Anyone has any knowledge about such situations ? Thanks.

• Amazon EC2, fastest way to get a node into an existing cluster

  - by imaginative

  I'm new to Amazon AWS. A lot of the time I hear about people folks spawning instances and almost instantly putting them behind a load balancer and into an existing cluster. In the traditional world of managed machines, this would include provisioning hardware, installing an OS, configuring the network on the machine and once the network is available, use a tool of your choice such as CFengine, Puppet or Chef to bootstrap the machine based on its class. It seems like there are "shortcuts" that are able to get a server of a particular class up and running in Amazon EC2. If I have a particular stack running on my server, such as erlang, tomcat6 etc.. what's the fastest way to get these up and running and hooked into Amazon's load balancer? From network, to software stack to kernel tuning? Is it a combination of creating an AMI then running a tool like Puppet against the new instance? Any idea

• Slick2d Spritesheet showing whole image

  - by BotskoNet

  I'm trying to show a single subimage from a sprite sheet. Using slick2d SpriteSheet class, all it's doing is showing me the entire image, but scaled down to fit the cell dimensions. The image is 96x192 and should have cells of 32x32. The code: SpriteSheet spriteSheet = new SpriteSheet("images/"+file, 32, 32 ); System.out.println("Horiz Count: " + spriteSheet.getHorizontalCount()); System.out.println("Vert Count: " + spriteSheet.getVerticalCount()); System.out.println("Height: " + spriteSheet.getHeight()); System.out.println("Width: " + spriteSheet.getWidth()); System.out.println("Texture Width: " + spriteSheet.getTextureWidth()); System.out.println("Texture Height: " + spriteSheet.getTextureHeight()); Prints: Horiz Count: 3 Vert Count: 6 Height: 192 Width: 96 Texture Width: 0.75 Texture Height: 0.75 Not sure what the texture dimensions refer to, but the rest is entirely accurate. However, when I draw the icon, the entire sprite image shows scaled down to 32x32: Image image = spriteSheet.getSprite(1, 0); // a test image.bind(); GL11.glEnable(GL11.GL_BLEND); GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA); GL11.glBegin(GL11.GL_QUADS); GL11.glTexCoord2f(0,0); GL11.glVertex2f(x,y); GL11.glTexCoord2f(1,0); GL11.glVertex2f(x+image.getWidth(),y); GL11.glTexCoord2f(1,1); GL11.glVertex2f(x+image.getWidth(),y+image.getHeight()); GL11.glTexCoord2f(0,1); GL11.glVertex2f(x,y+image.getHeight()); GL11.glEnd(); GL11.glDisable(GL11.GL_BLEND);

• Finding links among many written and spoken thoughts

  - by Peter Fren

  So... I am using a digital voice recorder to record anything I see important, ranging from business to private, from rants to new business ideas. Every finalized idea is one wma-file. I wrote a program to sort the wma-files into folders. From time to time I listen to the wma-files, convert them to text(manually) and insert them into a mindmap with mindmanager, which I sort hierarchically by area and type in turn. This works very well, no idea is being lost, when I am out of ideas for a special topic, I listen to what I said and can get started again. What could a search system look like that finds links between thoughts(written in the mindmap and in the wma files) or in general gives me good search results even when the keyword I searched for is not present but a synonym of it or related topic(for instance flower should output entries containing orchid aswell, even if they contain orchid but not the very keyword flower). I prefer something ready-made but small adjustments to a given system are fine aswell. How would you approach this task?

• Lightning fast forum based around metadata / tags? [closed]

  - by Dan W

  Possible Duplicate: What Forum Software should I use? I wonder if anything like this exists. I'd like to add a forum to my site, but instead of the usual forum/subforum/sub-subforum structure, I'd like to use a metadata/tag approach where everything exists as a single directory, and where there's a search field at the top which instantly (<0.5 sec) filters the threads to a particular keyword or keywords. Also, as the admin, I would be able to add highly visible buttons at the top, which can be clicked on for the main categories I choose for the forum (nevertheless, users can also add tags to their own threads outside of these default main tags I supply if they wish). This approach, if done properly, is more powerful, efficient, maintenance free, scalable and friendly than a standard forum, so I was hoping someone had the same idea and made something out of it. It couldn't be that hard. I'd want the speed to be up to (or near) the standard of this: http://forum.dlang.org/ Other forums (e.g.: phpBB) are orders of magnitude worse than that in terms of latency (posting or browsing), and I think that is wrong, even in principle ;)

• What options do I have for creating customized keyboard shortcuts?

  - by Moses

  As I am getting more heavily into programming as a job and no longer as a hobby, I am definitely in need of some ways to improve my productivity. One thing that would definitely help in that respect is being able to create customized keyboard shortcuts for text/code snippets. For instance, holding down CMD+L+O+R+E+M will output a paragraph or two of the Lorem ipsum filler text, or CMD+F+U creates a function declaration. What I am ideally looking for is a database where I can store formatted text snippets, bind them to my choice of keystrokes, and then have the text paste whenever I perform the associated keystrokes. Are there any stand-alone applications that can do this for a Mac. Also, are there any text editors / IDEs that have this ability built in?

• Animation API vs frame animation

  - by Max

  I'm pretty far down the road in my game right now, closing in on the end. And I'm adding little tweaks here and there. I used custom frame animation of a single image with many versions of my sprite on it, and controlled which part of the image to show using rectangles. But I'm starting to think that maybe I should've used the Animation API that comes with android instead. Will this effect my performance in a negative way? Can I still use rectangles to draw my bitmap? Could I add effects from the Animation API to my current frame-controlled animation? like the fadeout-effect etc? this would mean I wont have to change my current code. I want some of my animations to fade out, and just noticed that using the Animation API makes things alot easier. But needless to say, I would prefer not having to change all my animation-code. I'm bad at explaining, so Ill show a bit of how I do my animation: private static final int BMP_ROWS = 1; //I use top-view so only need my sprite to have 1 direction private static final int BMP_COLUMNS = 3; public void update(GameControls controls) { if (sprite.isMoving) { currentFrame = ++currentFrame % BMP_COLUMNS; } else { this.setFrame(1); } } public void draw(Canvas canvas, int x, int y, float angle) { this.x=x; this.y=y; canvas.save(); canvas.rotate(angle , x + width / 2, y + height / 2); int srcX = currentFrame * width; int srcY = 0 * height; Rect src = new Rect(srcX, srcY, srcX + width, srcY + height); Rect dst = new Rect(x, y, x + width, y + height); canvas.drawBitmap(bitmap, src, dst, null); canvas.restore(); }

• Making files generally available on Linux system (when security is relatively unimportant)?

  - by Ole Thomsen Buus

  Hi, I am using Ubuntu 9.10 on a stationary PC. I have a secondary 1 TB harddrive with a single big logical partition (currently formatted as ext4). It is mounted as /usr3 with options user, exec in /etc/fstab. I am doing highspeed imaging experiments. Well, only 260fps, but that still creates many individual files since each frames is saved as one png-file. The stationary is not used by anyone other than me which is why the default security model posed by ubuntu is not necessary. What is the best way to make the entire contents of /usr3 generally available on all systems. In case I need to move the harddrive to another Ubuntu 9.x or 10.x machine? When grabbing image with the firewire camera I use a selfmade grabbing software-utility (console based) in sudo-mode. This creates all files with root as owner and group. I am logged in as user otb and usually I do the following when having to make files generally available to otb: sudo chown otb -R * sudo chgrp otb -R * sudo chmod a=rwx -R * This takes some time since the disk now contains individual ~200000 files. After this, how would linux behave if I moved the harddrive to another system where the user otb is also available? Would the files still be accessible without sudo use?
