• Dynamic Subdomains

  - by crash

  On my new site I want to have dynamic subdomains. I'm trying to make it so that the subdomains use the same web root as the main domain, all under a single CodeIgniter installation. For example, subdomain.example.com would lead to example.com/subdomain, which is actually example.com/index.php/subdomain. I've already the DNS, virtual hosts set up but I"m getting caught up on the .htaccess. The effect of the linked htaccess is that when navigating to any subdomain, it gets caught up in an infinite loop. (Error log after one request.) It's the same effect for www., which should just resolve to the main domain.

• No internet connection for some programmes after installing ad hoc wireless network

  - by Michael

  After installing a wireless network (through the program iPhoneModem) several programmes have stopped working when connected to the Internet using another wireless connection. Working programmes: Firefox (browser) uTorrent (p2p) FileZilla (ftp) etc. Programmes that are not working: Chrome (browser) Digsby (IM client) etc. I'm running Windows 7. I have tried to disable Windows Firewall entirely as well as AVG anti virus, with no effect. I've tried to run the FixIt program from Microsoft adressing a corrupt TCP/IP stack. This too had no effect. Any suggestions?

• Default Keyboard for new users in Windows 7

  - by xited

  I just installed Windows 7 and I want all users signing in to the computer to see the Language Bar customized with the following three languages: "English (American)" "French (Standard)" "Chinese (Simplified PRC)" I am running the following four lines of code at log on in order to change the registry such that each user will see the language bar, and then have access to the three keyboard layouts mentioned above. reg add "HKCU\Software\Microsoft\CTF\LangBar" /v ShowStatus /t REG_DWORD /d 4 /f reg add "HKCU\Keyboard Layout\Preload" /v 2 /d 0000040c reg add "HKCU\Keyboard Layout\Preload" /v 3 /d 00000c0a reg add "HKCU\Keyboard Layout\Preload" /v 4 /d 00000804 The above works fine, but with one small/major inconvenience: the user has to log off and then log back on in order for these changes to take effect and see the language bar, as described above. The question becomes: How can I force these changes to take effect so that users don't have to log off and then log back in to see the language bar. This has to be done automatically when users log in.

• IIS: redirect everything to another URL, except for one Directory

  - by DrStalker

  I have an IIS server (IIS 6, Win 2003) that hosts the site http://www.foo.com. I want any request to http://foo.com (no matter what path/filename is used) to redirect to http://www.bar.org/AwesomePage.html UNLESS the request is for http://www.foo.com/specialdir, in which case the HTML files in the local directory specialdir should be used. The problem I have is once the redirect is set it also affects /specialdir - even if I right click on that directory and select "content should come from ... local directory" that change does not take effect, and the directory still shows as redirecting to http://www.bar.org/AwesomePage.html. The same thing happens if I try to set individual files to load from the local system instead of redirecting - IIS gives no error, but the change does not take effect and the files still show as being redirected. How can I set specialdir to override the redirection to the new URL?

• Best way to use mod_rewrite to replace WordPress pages with static files

  - by David Moles

  Here's the situation: I've got an old WordPress installation that I'd like to archive as static files, but I'd also like to preserve old URLs. I've already created the static archive with wget and sorted out the filenames and links. Now I'd like to configure Apache to intercept requests for the old dynamic URL and replace them with the new static one, e.g.: http://www.example.org/log/?p=1234 or http://www.example.org/log/index.php?p=1234 should redirect to http://www.example.org/log/archives/1234.html I've tried adding the following to the VirtualHost config for example.org, but to no effect -- I just get the PHP page. RewriteCond %{REQUEST_URI} /log/ RewriteCond %{QUERY_STRING} p=([^&;]*) RewriteRule ^/$ http://%{SERVER_NAME}/log/archives/%1.html [R,L] I've enabled logging and I can see what look like other rules being applied, but not this one. None of my other guesses at match patterns for %{REQUEST_URI} seem to have any effect either (log, log/, log.*, even .*). I'm new to mod_rewrite and this is mostly cargo cult, so I'm pretty sure I've gotten it wrong. Anyone know what I should be doing here?

• Cached css/javascript files on Sun Java System Web Server

  - by Derp

  I'm doing front-end web development in a Solaris 10 / Sun Java System Web Server 7.0U2 environment. I have noticed that changes to static css or javascript files often do not take effect immediately, whereas changes to static html files always do. My best guess is that a default setting in the web server causes it to cache certain file types in order to provide reasonable performance out of the box. I don't have the admin server running--I'll need to edit the config files by hand. What change(s) can I make so that all of my css and javascript edits take effect immediately? Thanks!

• vsftpd chroot_local_user does nothing

  - by Reinderien

  Hello all. I'm setting up a vsftpd server on: Linux 2.6.32-26-server #48-Ubuntu SMP Wed Nov 24 10:28:32 UTC 2010 x86_64 GNU/Linux When I set chroot_local_user=YES, there is no effect (I can still see / when I log in). There is nothing in syslog or /var/log/vsftpd.log to indicate what's wrong. I know that I'm editing the right conf file and that other settings do come into effect when I restart the daemon, because these work: ssl_enable=YES force_local_data_ssl=YES force_local_logins_ssl=YES Any idea what's wrong? Thanks.

• What is the probable failure - no BSOD, no event log, monitors sleeping, force reboot required

  - by Tyler

  Every 3 to 15 days, my PC freezes. This typically happens when the computer is idle, I'm coming home from work, back from vacation, etc. It's never happened while using my computer. The monitors are in power save mode The Caps Lock light on the (wireless) keyboard doesn't work Ctrl-alt-del has no effect, mouse (wireless) has no effect The hardware reset button and single press of power putton have no effect Computer does not appear on the network No BSOD, no memory dump Event logs have no errors or indications of problems near the time of crash. Only messages after reboot indicating that there was a reboot without a clean shutdown. Windows is set to never put the computer to sleep (just the display) Here are the vital stats of the build: OS Windows 8 Pro 64-bit CPU Intel i5-2400 Mobo Intel BOXDP67DE Micro ATX GPU MSI N460GTX Cyclone768D5/OC RAM CORSAIR XMS3 8GB (2 x 4GB) CMX8GX3M2A1333C9 PSU SeaSonic X Series X650 Gold System Drive Samsung 840 Pro 256 GB SSD Data Drive 2 x Western Digital WD20EARS 2TB in hardware RAID 1 Optical Lite-On DVD burner IHAS424-98 And here is the story of how the problem developed and what I've done to diagnose: January 2011, system built with Windows 7 64-bit, runs great. March 2011, Intel replaced the mobo because of the bad sata controllers. October 2012, upgrade to Windows 8 (problems start shortly after). January 2013, system freezes and causes network to fail for the whole house. Unplug the network cable and other devices and PCs can use the internet. Plug it back in, internet goes away for everyone. Reboot and everything is fine. March 2013, install Intel Gigabit CT PCI-E NIC, disable mobo nic in bios. Network strangeness goes away. Freezes are less frequent. Memtest shows no problems (20 passes). Early June 2013, replace Antec PSU with SeaSonic PSU. Mid June 2013, replace OCZ Vertex 2 SSD with Samsung SSD. Late June 2013, get frustrated and hope the community has some good ideas (I'm running out of budget to replace parts). My next plan of attack is setting "Turn off display" to Never and using a screen saver to see how that reacts on the next freeze. It makes me sad to waste power for up to 15 days though. Has anyone out there seen a problem like this? Any ideas on what kind of malfunction would act this way? Ideas of other diagnostic steps to take?

• Spoof MAC address in Windows 7: Bypass

  - by lpd

  I am trying to spoof the MAC address of my new Win7 laptop. To do so I tried specifying an alternate value from the Device Manager which took no effect. I also tried from the registry, as per other threads here, to no avail. Interestingly I also found the registry contained a path 000X\Ndi\params\NetworkAddress\default REG_SZ, but changing that had no effect either :( I can only guess I share the same issue here: http://forums.anandtech.com/showthread.php?t=2096480 as the wireless adaptor is the same brand bundled with the same operating system. So my question is - is there anything better I can do to achieve a spoofed physical address than rollback the drivers to some older version?

• Config Time Service on Server 2008 DC using Group Policy Only

  - by Ed Fries

  I want to configure the Time Service using only GP in a Server 2008 R2 domain. I have created a GP as follows: Computer Config, Policies, Administrative Templates, System, Windows Time Policy: =Global Configuration Settings -Enabled w/ default settings. Computer Config, Policies, Administrative Templates, System, Windows Time Policy,Time Providers: =Configure Windows NTP Client -Enabled w/ default settings. =Enable Windows NTP Client -Enabled w/ default settings. =Enable Windows NTP Server -Enabled w/ default settings. The policy is linked, enforced and applied to Domain Controllers OU. The GP modeling results shows the policy is in effect on the DC (Single DC domain) and the DC is recognized as the PDC emulator. I have run gpupdate /force and logged off/on. The issue is that the DC shows the time source as internal. I understand I can force this at the cmd line using w32tm to set the peer but I would like to understand what is missing in the GP. The default NTP Client GP setting includes time.windows.com,0x9 as the source but it does not appear to be taking effect.

• Rendering shadow sprites in cocos2d-x

  - by lukeluke

  I am writing a 2D game with cocos2d-x. I want to put a "shadow" sprite on a background sprite using the equation: MAX(0, Cd*1 - Cs*S) where Cd is the destination color (that is, a background pixel), Cs is the source color (the shadow pixel) , S is the scale factor (between 0 and 1). The MAX() function is used to avoid negative results. This is a lighting effect: when the shadow sprite pixel is 0, there is no effect on the background pixel, otherwise, the background pixel becomes darker. Now, the only way that comes to my mind is to change the blending equation to GL_FUNC_SUBTRACT, but it doesn't compile with cocos2d-x (can't found it)... I would subclass the CCSprite class in order to implement the draw() method in order to change, when needed, the blending equation, call the original draw() method and restore the blending equation to its previous state at the end of the method. So my questions are two: how to use glBlendEquation() with cocos2d-x? Keep in mind that i am writing a game for iphone/android/windows. are shadows handled this way in 2D games? Thx

• Follow point of interest by applying torque

  - by azymm

  Given a body with an orientation angle and a point of interest or targetAngle, is there an elegant solution for keeping the body oriented towards the point of interest by applying torque or impulses? I have a naive solution working below, but the effect is pretty 'wobbly', it'll overshoot each time, slowly getting closer to the target angle - undesirable effect in my case. I'd like to find a solution that is more intelligent - that can accelerate to near the target angle then decelerate and stop right at the target angle (or within a small range). If it helps, I'm using box2d and the body is a rectangle. def gameloop(dt): targetAngle = get_target_angle() bodyAngle = get_body_angle() deltaAngle = targetAngle - bodyAngle if deltaAngle > PI: deltaAngle = targetAngle - (bodyAngle + 2.0 * PI) if deltaAngle < -PI: deltaAngle = targetAngle - (bodyAngle - 2.0 * PI) # multiply by 2, for stronger reaction deltaAngle = deltaAngle * 2.0; body.apply_torque(deltaAngle); One other thing, when body has no linear velocity, the above solution works ok. But when the body has some linear velocity, the solution above causes really wonky movement. Not sure why, but would appreciate any hints as to why that might be.

• OpenGL ES Shader help (Blending)

  - by Chris

  Earlier I required assistance getting to grips with how to retain the alpha channel of a transparent texture in my colourised texture shader program. Whilst playing with that first version of my program (before obtaining the solution to my first requirement), I managed to enable transparency for the whole texture (effectively blending via GLSL), and I quite liked this, and I would now like to know if and how it is possible to retain this blending effect, on top of the existing output without affecting the original alpha channel - as I don't know how to input this transparency via the parameter that is already being provided with the textures alpha channel. A basic example of the blending program I am referring to (minus any other functionality) is as follows... varying vec2 texCoord; uniform sampler2D texSampler; void main() { gl_FragColor = vec4(texture2D(texSampler,texCoord).xyz,0.5); } Where 0.5 is the transparency (blending effect) of the whole texture. This is the current version of my program, which provides the ability to colour a texture according the colour parameter passed to the program, and retains the alpha channel of the original texture. varying vec2 texCoord; uniform sampler2D texSampler; uniform vec3 colour; void main() { gl_FragColor = vec4(colour,1) * vec4(texture2D(texSampler,texCoord).xyz,texture2D(texSampler,texCoord).w); } I need to know if it is possible to apply transparency on top this program, without affecting the original alpha channel which I have already preserved. I hope this makes enough sense, I am sure it is possible, and if so I should imagine it is rather simple, but this has me stumped. Any help much appreachiated. Cheers, Chris

• SQL SERVER – Table Variables and Transactions – SQL in Sixty Seconds #007 – Video

  - by pinaldave

  Today’s SQL in Sixty Seconds video is inspired from my presentation at TechEd India 2012 on Misconception and Resolution. Quite often I have seen people getting confused with certain behavior of the T-SQL. They expect SQL to behave certain way and SQL Server behave differently. This kind of issue often creates confusion and frustration. Sometime I have seen them also confusing it with bug and submitting the bug, where reality is totally different. Similar concept which are going to see today. I have seen quite commonly developer assuming that table various will be rolled back when transaction is rolled back. This sixty seconds video describes that table various are not rolled back when transactions are rolled back. More on Errors: Difference Temp Table and Table Variable – Effect of Transaction Effect of TRANSACTION on Local Variable – After ROLLBACK and After COMMIT Debate – Table Variables vs Temporary Tables – Quiz – Puzzle – 13 of 31 I encourage you to submit your ideas for SQL in Sixty Seconds.

• Calculating Screen Resolutions Using WPF

  - by Jeff Ferguson

  WPF measures all elements in device independent pixels (DIPs). These DIPs equate to device pixels if the current display monitor is set to the default of 96 DPI. However, for monitors set to a DPI setting that is different than 96 DPI, then WPF DIPs will not correspond directly to monitor pixels. Consider, for example, the WPF properties SystemParameters.PrimaryScreenHeight and SystemParameters.PrimaryScreenWidth. If your monitor resolution is set to 1024 pixels wide by 768 pixels high, and your monitor is set to 96 DPI, then WPF will report the value of SystemParameters.PrimaryScreenHeight as 768 and the value of SystemParameters.PrimaryScreenWidth as 1024. No problem. This aligns nicely because the WPF device independent pixel value (96) matches your monitor's DPI setting (96). However, if your monitor is not set to display pixels at 96 DPI, then SystemParameters.PrimaryScreenHeight and SystemParameters.PrimaryScreenWidth will not return what you expect. The values returned by these properties may be greater than or less than what you expect, depending on whether or not your monitor's DPI value is less than or greater than 96. Since the SystemParameters.PrimaryScreenHeight and SystemParameters.PrimaryScreenWidth properties are WPF properties, their values are measured in WPF DIPs, rather than taking monitor DPI into effect. Once again: WPF measures all elements in device independent pixels (DIPs). To combat this issue, you must take your monitor's DPI settings into effect if you're looking for the monitor's width and height using the monitor's DPI settings. The handy code block below will help you calculate these values regardless of the DPI setting on your monitor: Window MainWindow = Application.Current.MainWindow; PresentationSource MainWindowPresentationSource = PresentationSource.FromVisual(MainWindow); Matrix m = MainWindowPresentationSource.CompositionTarget.TransformToDevice; DpiWidthFactor = m.M11; DpiHeightFactor = m.M22; double ScreenHeight = SystemParameters.PrimaryScreenHeight * DpiHeightFactor; double ScreenWidth = SystemParameters.PrimaryScreenWidth * DpiWidthFactor; The values of ScreenHeight and ScreenWidth should, after this code is executed, match the resolution that you see in the display's Properties window.

• Hiding the Flash Message After a Time Delay

  - by Madhan ayyasamy

  Hi Friends,The flash hash is a great way to provide feedback to your users.Here is a quick tip for hiding the flash message after a period of time if you don’t want to leave it lingering around.First, add this line to the head of your layout to ensure the prototype and script.aculo.us javascript libraries are loaded:Next, add the following to either your layout (recommended), your view templates or a partial depending on your needs. I usually add this to a partial and include the partial in my layouts. "flash", :id = flash_type % "text/javascript" do % setTimeout("new Effect.Fade('');", 10000); This will wrap the flash message in a div with class=‘flash’ and id=‘error’, ‘notice’ or ‘warn’ depending on the flash key specified.The value ‘10000’ is the time in milliseconds before the flash will disappear. In this case, 10 seconds.This function looks pretty good and little javascript stunts like this can help make your site feel more professional. It’s also worth bearing in mind though, not everybody can see well or read as quickly as others so this may not be suitable for every application.Update:As Mitchell has pointed out (see comments below), it may be better to set the flash_type as the div class rather than it’s id. If there is the possibility that you’ll be showing more than one flash message per page, setting the flash_type as the div id will result in your HTML/XHTML code becoming invalid because the unique intentifier will be used more than once per page.Here is a slightly more complex version of the method shown above that will hide all divs with class ‘flash’ after a time delay, achieving the same effect and also ensuring your code stays valid with more than one flash message! "flash #{flash_type}" % "text/javascript" do % setTimeout("$$('div.flash').each(function(flash){ flash.hide();})", 10000); In this example, the div id is not set at all. Instead, each flash div will have class “div” and also class of the type of flash message (“error”, “warning” etc.).Have a Great Day..:)

• How to create a "retro" pixel shader for transformed 2D sprites that maintains pixel fidelity?

  - by David Gouveia

  The image below shows two sprites rendered with point sampling on top of a background: The left skull has no rotation/scaling applied to it, so every pixel matches perfectly with the background. The right skull is rotated/scaled, and this results in larger pixels that are no longer axis aligned. How could I develop a pixel shader that would render the transformed sprite on the right with axis aligned pixels of the same size as the rest of the scene? This might be related to how sprite scaling was implemented in old games such as Monkey Island, because that's the effect I'm trying to achieve, but with rotation added. Edit As per kaoD's suggestions, I tried to address the problem as a post-process. The easiest approach was to render to a separate render target first (downsampled to match the desired pixel size) and then upscale it when rendering a second time. It did address my requirements above. First I tried doing it Linear -> Point and the result was this: There's no distortion but the result looks blurred and it loses most of the highlights colors. In my opinion it breaks the retro look I needed. The second time I tried Point -> Point and the result was this: Despite the distortion, I think that might be good enough for my needs, although it does look better as a still image than in motion. To demonstrate, here's a video of the effect, although YouTube filtered the pixels out of it: http://youtu.be/hqokk58KFmI However, I'll leave the question open for a few more days in case someone comes up with a better sampling solution that maintains the crisp look while decreasing the amount of distortion when moving.

• Algorithmically generating neon layers on pixel grid

  - by user190929

  In an attempt at a screensaver I am making, I am a fan of neo-like graphics, which, of course, look great against a black background. As I understand it, neon, graphically speaking, is essentially a gradient of a color, brightest in the center, and gets darker proceeding outward. Although, more accurate is similar, but separating it into tubes and glow. The tubes are mostly white, while the glow is where most of the color is seen. Well... the tubes could also be a light variant of the color, you could say. The glow is darker. Anyhow, my question is, how could you generate such things given an initial pattern of pixels that would be the tubes? For example, let's say I want to make a neon 'H'. I, via the libraries, can attain the rectangles of pixels which represent it, but I want to make it look neonized. How could I algorithmically achieve such an effect given a base tube shape and base color? EDIT: ok, I mistated that. Got a bit distracted. My purpose for this was similar to a neon effect, but not. Sorry about that. What I am looking for is something like this: Start with a pattern of pixels: [!][!][!][!][!][!][!][!] [!][!][O][!][!][!][!][!] [!][!][O][O][!][!][!][!] [!][!][!][!][O][!][!][!] [!][!][!][!][!][!][!][!] How to I find the U pixels? [!][E][E][E][!][!][!][!] [!][E][O][E][E][!][!][!] [!][E][O][O][E][E][!][!] [!][E][E][E][O][E][!][!] [!][!][!][E][E][E][!][!] Sorry if that looks bad.

• How to balance a non-symmetric "extension" based game?

  - by Klaim

  Most strategy games have fixed units and possible behaviours. However, think of a game like Magic The Gathering : each card is a set of rules. Regularly, new sets of card types are created. I remember that the firsts editions of the game have been said to be prohibited in official tournaments because the cards were often too powerful. Later extensions of the game provided more subtle effects/rules in cards and they managed to balance the game apparently effectively, even if there is thousands of different cards possible. I'm working on a strategy game that is a bit in the same position : every units are provided by extensions and the game is thought to be extended for some years, at least. The effects variety of the units are very large even with some basic design limitations set to be sure it's manageable. Each player choose a set of units to play with (defining their global strategy) before playing (like chooseing a themed deck of Magic cards). As it's a strategy game (you can think of Magic as a strategy game too in some POV), it's essentially skirmish based so the game have to be fair, even if the players don't choose the same units before starting to play. So, how do you proceed to balance this type of non-symmetric (strategy) game when you know it will always be extended? For the moment, I'm trying to apply those rules but I'm not sure it's right because I don't have enough design experience to know : each unit would provide one unique effect; each unit should have an opposite unit that have an opposite effect that would cancel each others; some limitations based on the gameplay; try to get a lot of beta tests before each extension release? Looks like I'm in the most complex case?

• Creating a newspaper that effects the game's economy?

  - by zardon

  I am writing a game in Objective C/cocos2d where a newspaper is a central part of what controls or rather effects the game's world economy as well as what a city might do (such as increase X, reduce Y) The newspaper is a bit like a "Chance card" in Monopoly, it has an effect on something. My question is, what is the best way to do write a newspaper that has both a random and specific effect within the game. Would the best strategy be to write out all the things a newspaper can affect, a PLIST of headlines (with placeholders). I think Tiny Tower uses a PLIST of events and it randomly picks an event, but I'm not sure how it actually parses it because certain events do different things. But then how do I parse all the scenarios that a newspaper can deliver? A big switch statement seems very long and complicated to do. I am wondering if there is a simpler way to handle this kind of thing. Related to this is that there might be no news that day and I'm not sure what the newspaper should display, should it just display the last headline? So, in summary. 1) A newspaper generates a headline, it affects different things, such as the world economy, prices, how city reacts 2) I need the newspaper to generate headlines (although there may be days when there are no headlines at all), but I am not sure how to parse it without using a big-ass switch statement. Thanks in advance.
