  • Disable DirectDraw, but still have Direct3D?

    - by GodsBoss
    I have a Windows XP SP3 machine, with up-to-date patches. It has DirectX 9.0c, version number 4.09.00.0904. Can I disable DirectDraw, but have Direct3D still active? I read the Wikipedia articles about DirectDraw and Direct3D, but do not know if I understand them correctly: That is, it contains many commands for 3D rendering; however, since version 8, Direct3D has superseded the old DirectDraw framework and also taken responsibility for the rendering of 2D graphics. Does that mean DirectDraw is now a part of Direct3D? Because I cannot disable DirectDraw without disabling Direct3D, but it works the other way around.

  • Possible to get SSD TRIM (discard) working on ext4 + LVM + software RAID in Linux?

    - by Don MacAskill
    We use RAID1+0 with md on Linux (currently 2.6.37) to create an md device, then use LVM to provide volume management on top of the device, and then use ext4 as our filesystem on the LVM volume groups. With SSDs as the drives, we'd like to see the TRIM commands propagate through the layers (ext4 - LVM - md - SSD) to the devices. It looks like recent 2.6.3x kernels have had a lot of new SSD-related TRIM support added, including lots more coverage of Device Mapper scenarios, but we still can't seem to get it to cascade down properly. Is this possible yet? If so, how? If not, is any progress being made?

  • Help organising controllers logically

    - by kenny99
    Hi guys, I'm working on a site which i'm developing using an MVC structure. My models will represent all of data in the site, but i'm struggling a bit to decide on a good controller structure. The site will allow users to login/register and see personal data on a number of pages, but also still have access to public pages, e.g FAQs, Contact page etc. This is what I have at the moment... A Template Controller which handles main template display. The basic template for the site will remain the same whether or not you are logged in. A main Website Controller which extends the Template Controller and handles basic authentication. If the user is logged in, a User::control_panel() method is called from the constructor and this builds the control panel which will be present throughout the authenticated session. If user is not logged in, then a different view is loaded instead of the control panel, e.g with a login form. All protected/public page related controllers will extend the website controller. The user homepage has a number of widgets I want to display, which I'm doing via a Home Controller which extends the Website Controller. This controller generates these widgets via the following static calls: $this->template->content->featured_pet = Pet::featured(); $this->template->content->popular_names = Pet::most_popular(); $this->template->content->owner_map = User::generate_map(); $this->template->content->news = News::snippet(); I suppose the first thing I'm unsure about is if the above static calls to controllers (e.g Pet and User) are ok to remain static - these static methods will return views which are loaded into the main template. This is the way I've done things in the past but I'm curious to find out if this is a sensible approach. Other protected pages for signed in users will be similar to the Home Controller. Static pages will be handled by a Page Controller which will also extend the Website Controller, so that it will know whether or not the user control panel or login form should be shown on the left hand side of the template. The protected member only pages will not be routed to the Page Controller, this controller will only handle publicly available pages. One problem I have at the moment, is that if both public and protected pages extend the Website Controller, how do I avoid an infinite loop - for example, the idea is that the website controller should handle authentication then redirect to the requested controller (URL), but this will cause an infinite redirect loop, so i need to come up with a better way of dealing with this. All in all, does this setup make any sense?! Grateful for any feedback.

  • What is validating a binary search tree?

    - by dotnetdev
    I read on here of an exercise in interviews known as validating a binary search tree. How exactly does this work? What would one be looking for in validating a binary search tree? I have written a basic search tree, but never heard of this concept. Thanks

  • Update mysql database with arpwatch textfile database

    - by bVector
    I'm looking to keep arpwatch entries in a mysql database to crossreference with other information I'm storing based on mac addresses. I've manually imported the arpwatch database into my mysql database, but being a novice with databases I'm not sure what the best way to continually update the database with new entries without creating duplicates would be. None of the fields can be unique, as even the time is duplicated frequently. I'm not interested in the actual arpwatch events like flip flop or new station, just the mac/ip/time pairings. Would a simple bash (or sql) shell script do the trick? Would it be possible to make the mac address plus the time be a composite key of some sort? the database is called utility, table is arpwatch, columns are mac, ip, time a seperate table named 'hosts' with columns mac, ip, type, hostname, location, notes has mac as the primary key. This table will correlate different ip addresses that a mac had over time using the arpwatch column initial import was done with MySQL Workbench using INSERT INTO commands with creative search and replace on the text file

  • Configuring Notepad++ to run knitr2pdf

    - by Stat-R
    Sorry for such a basic question but since I do not have a degree in programming... I am a user of R, knitr and Notepad++. I was trying to configure Notepad++ to run pdflatex and knitr(knit2pdf). By googling I found how to do it for pdflatex but I did not find anything for sweave/knitr. The following are the good ones for pdflatex http://www2.sofi.su.se/~mbe/docs/npp_r_latex.pdf http://www.tlhiv.org/ma497/software/ I inserted cmd /c cd /d "$(CURRENT_DIRECTORY)" && pdflatex.exe -shell-escape "$(FILE_NAME)" into the runrun menu in Notepad++. I do not fully understand the command though. I will appreciate any help on this. Please direct me if you can to any resource for learning these commands. I will be grateful to get any help in configuring Notepad++ for running knitr.

  • What is the difference between a segmentation fault and a stack overflow?

    - by AruniRC
    For example when we call say, a recursive function, the successive calls are stored in the stack. However, due to an error if it goes on infinitely the error is 'Segmentation fault' (as seen on GCC). Shouldn't it have been 'stack-overflow'? What then is the basic difference between the two? Btw, an explanation would be more helpful than wikipedia links (gone through that, but no answer to specific query).

  • What makes good software good?

    - by Jonta
    People probably have a lot of different answers here, like good...: scalability, speed, usability, stability, consistency, completeness, absence of bugs, accessibility, documentation, code-quality and so on. There are a lot of philosophies on development of software. Like the UNIX-philosophy. Often vague and not easy to understand. I am looking for statements such as the one cited below. Which you can ask about the software when it's in the design-stage, is ready to be coded, and has been coded and is ready for launch. The software I am talking about, is of course the software made for the end-user. Ken Rockwell wrote: "I expect that it will let me get more accomplished in less time." (Here one could ask "will this let me get more accomplished in less time?")

  • .htpasswd under IIS - does it work?

    - by Cyrcle
    I'm trying to password protect a directory on a server that's running IIS. I've put the following in the .htaccess file in that directory - AuthName "Restricted Area" AuthType Basic AuthUserFile /path/.htpasswd AuthGroupFile /dev/null require valid-user I've tried a whole bunch of different paths and although it's asking for a username and password it won't take it. I've tried using the path provided by _SERVER["PATH_TRANSLATED"] but that's no help either. Is this a problem with my path, or does IIS just not support .htpasswd?

  • Microsoft Robotics Studio with Wine ? Is it possible ?

    - by Arkapravo
    I am using Ubuntu 9.10 and I am a bit of a robotics enthusiast. I have used KiKS (in MATLAB for simulating Khepera robots), MobotSim (in Windows, simulates a point like robot using a BASIC editor) and Player Stage/Gazebo (with C/C++ on Ubuntu Linux). My question, can MS Robotics Studio be installed in Ubuntu Linux using Wine (I am using 1.1.31) ? Has anyone done it ? Thanks for your reply !

  • What does it call in GWT to make 2 UI consistent?

    - by DucDigital

I currently don't understand the basic of this (In GWT, i think it implement Comet), so is there anyone can give me a term or definition for this? so I can get it on Google for more information? Thank you very much

  • Abstraction is for lame programmers ? [closed]

    - by Zaban Khuli
    Hi, there's this senior developer in my company who's (in his own opinion) a pretty good C programmer. I happen to be from functional background (ML, to be specific) and so for me composition and abstraction are the two basic elements of programming. But this MrSmartyPants has got some kind of superiority complex and he'd always argue with me that abstraction is for lame programmers and _real_ programmers do not need it. Is it a problem with this guy or all C programmers have this opinion that abstraction is for lame programmers?

  • How to copy directories using debugfs?

    - by tjbp
    The debugfs manpage gives the impression that the command 'rdump . .' will recursively copy all files found on the specified filesystem from the debugfs cwd to the native filesystem's cwd. Instead I seem to receive a syntax error, and no copy is initiated? These are the commands I run: cd /path/to/transfer/destination debugfs /dev/sda1 -R rdump . . My task is to copy the entire contents of a clean yet unmountable USB storage device to its host machine's HD. The host machine does not support the inode size used by the USB device's filesystem (256) and its software is not upgradeable, so my intention was to use debugfs to transfer the files. If anyone has any other suggestions for this task I'd be grateful.

  • Easy Deployment Split Tunnel VPN Connection

    - by Joey Harris
    I was wondering if anybody could offer some insight as to how I can mass deploy VPN connection settings that support split tunneling. It has to work on both Mac and Windows systems though if a script is used, it obviously can be 2 separate scripts for both platforms. I will be setting up a Windows server with a file server and Exchange server and to access the file server I will have the clients go through VPN because we will have sensitive data. I don't want the servers network to be bogged down with the clients normal internet traffic so I will be needing some way to setup split tunneling on the clients without them having to put in a few commands every time to setup the static routes. Ive looked at Cisco VPN client but I want to try and stick with windows RRAS and avoid buying a Cisco VPN endpoint. Im basically looking for a good VPN client that can support split tunneling and mass deployment.

  • Scriptable FTPS client able to send Keep Alive to control port?

    - by schultkl
    We need a FTP client that satisfies the following constraints: Windows Command-line scriptable, so we can automate it...sorry, FileZilla (?) FTPS, as it seems to perform better than SFTP The ability to send KeepAlive commands to the FTPS control port No passwords sent on the command line...sorry, curl Number 4, above, is critical: we have set KeepAlive in some other clients (e.g., CoreFTP LE) but we seem to have some routing equipment in the server environment which drops our connection when transferring a 7GB+ file. We have also set passive mode and "resume transfer" functionality seems currently broken with this secure file transport server...so we need to download the file in one go. What FTPS clients might meet our needs?

    - by Joshua Robison
    My network is as follows: Internet Provider's DSL modem connected to Internet Provider's router connected to My Buffalo Wireless router connected to My Toshiba Laptop via WEP network My Toshiba Laptop is running LMDE Linux Mint Debian Edition Service Pack 3 i686 kernel I have experience using various routers and their configuration settings but for some reason I can not access my wireless router. In my cromium browser I tried the following ip addresses: Standard Usual IPs : 192.168.1.1, 192.168.0.1 (connection hangs and goes no where) On the back of my router: 192.168.11.1, 192.168.11.100 (connection hangs and goes nowhere ) In some tcpip info: 192.168.24.1 (unable to connect error message) If someone could give me some terminal commands that will help me find my wireless router address or some trouble shooting ideas, I would be very thankful.

  • FTP an entire folder via the command line

    - by Chris Southam
    I'm looking so migrate some websites to a new server. I have SSH access to the current one but only FTP access to the new one. How can I via Centos and SSH copy entire folders to the new server via FTP? I can log into the new server via the built in FTP client on Centos but I'm not sure of the commands after this. I need to move the httpdocs folder from the old to the public_html folder of the new server. I'd love to do this server to server as it'll be a lot quicker than download - upload via my broadband connection. Yours, Chris

  • HTTP request, strange socket behavoir

    - by hoodoos
    I expirience strange behavior when doing HTTP requests through sockets, here the request: POST https://test.com:443/service/XMLSelect HTTP/1.1 Content-Length: 10926 Host: test.com User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 1.0.3705) Authorization: Basic XXX SOAPAction: http://test.com/SubmitXml Later on there goes body of my request with given content length. After that I recive something like: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Type: text/xml;charset=utf-8 Transfer-Encoding: chunked Date: Tue, 30 Mar 2010 06:13:52 GMT So everything seem to be fine here. I read all contents from network stream and successfuly recieve response. But my socket which I'm doing polling on switches it's modes like that: write ( i write headers and request here ) read ( after headers sent i begin to recieve response ) write ( STRANGE BEHAVIOUR HERE. WHY? here i send nothing really ) read ( here it switches to read back again ) last two steps can repeat several times. So I want to ask what leads for socket's mode change? And in this case it's not a big problem, but when I use gzip compression in my request ( no idea how it's related ) and ask server to send gzipped response to me like this: POST https://test.com:443/service/XMLSelect HTTP/1.1 Content-Length: 1076 Accept-Encoding: gzip Content-Encoding: gzip Host: test.com User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 1.0.3705) Authorization: Basic XXX SOAPAction: http://test.com/SubmitXml I recieve response like that: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Encoding: gzip Content-Type: text/xml;charset=utf-8 Transfer-Encoding: chunked Date: Tue, 30 Mar 2010 07:26:33 GMT 2000 ? I recieve a chunk size and GZIP header, it's all okay. And here's what is happening with my poor little socket meanwhile: write ( i write headers and request here ) read ( after headers sent i begin to recieve response ) write ( STRANGE BEHAVIOUR HERE. And it finally sits here forever waiting for me to send something! But if i refer to HTTP I don't have to send anything more! ) What can it be related to? What it wants me to send? Is it remote web server's problem or do I miss something? PS All actual service references and login/passwords replaced with fake ones :)

  • Google Maps API V3 and stringByEvaluatingJavaScriptFromString?

    - by Joseph
    Hi, I'm writing up an iPhone app using the Google Maps API V3, and I was wondering if it is still possible the use the stringByEvaluatingJavaScriptFromString function in the (void)webViewDidFinishLoad:(UIWebView *)webView function? A simple example being changing the map type (Assuming basic map setup): - (void)webViewDidFinishLoad:(UIWebView *)webView{ [webView stringByEvaluatingJavaScriptFromString:@"map.setMapTypeId(google.maps.MapTypeId.SATELLITE);"];} This was very possible the the 2.0 API, but I can't seem to get it right in the 3.0 API. Any insight would be much appreciated.
