• How to get a Toshiba L505 to boot USB or CD

  - by ShroudedCloud

  OK, have a Toshiba L505 (not sure of the extended model number) that got a virus on Windows and will no longer will boot into that, so I'm trying to revive it with Ubuntu. Problem is, when I tell it to boot into a USB image of 12.04 32- or 64-bit, 13.04 64-bit, or elementary Luna 32-bit, it gives me some screen with a copyright from 2000 for Intel, invariably spits out a "media not recognized" type of error and then says PXE-ROM exiting. Well, that's annoying. So I went in with a CD (12.04 x86_64 having tried 32-bit in the past as well). Boot menu, select, starts running. Seeing the loading screen for Ubuntu, going well... until it's not. Again, invariably, it fails. The CD drive will cease spinning at around the same time each time and then the laptop will stop doing everything altogether (at least, everything spins down and it goes quiet). As far as I can tell, it's not to do with what function is being loaded from the CD at the time (because that bit is variable). I'd love to be able to boot from USB (since it will be all but required going forward), but getting the CD to work would be wondrous too. Anyone have any ideas of where I can go from here to try to fix this? My friends and I have turned up nothing.

• Simple Architecture Verification

  - by Jean Carlos Suárez Marranzini

  I just made an architecture for an application with the function of scoring, saving and loading tennis games. The architecture has 2 kinds of elements: components & layers. Components: Standalone elements that can be consumed by other components or by layers. They might also consume functionality from the model/bottom layer. Layers: Software components whose functionality rests on previous layers (except for the model layer). -Layers: -Models: Data and it's behavior. -Controllers: A layer that allows interaction between the views and the models. -Views: The presentation layer for interacting with the user. -Components: -Persistence: Makes sure the game data can be stored away for later retrieval. -Time Machine: Records changes in the game through time so it's possible to navigate the game back and forth. -Settings: Contains the settings that determine how some of the game logic will apply. -Game Engine: Contains all the game logic, which it applies to the game data to determine the path the game should take. This is an image of the architecture (I don't have enough rep to post images): http://i49.tinypic.com/35lt5a9.png The requierements which this architecture should satisfy are the following: Save & load games. Move through game history and see how the scoreboard changes as the game evolves. Tie-breaks must be properly managed. Games must be classified by hit-type. Every point can be modified. Match name and player names must be stored. Game logic must be configurable by the user. I would really appreciate any kind of advice or comments on this architecture. To see if it is well built and makes sense as a whole. I took the idea from this link. http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller

• CentOS Live CD Creation issues

  - by Dheeraj

  I am creating my customized CentOS 6.3 Live CD. I am following information given at https://projects.centos.org/trac/livecd/wiki/GetToolset My "livecd-creator" command completes successfully and an ISO image is created. But when I try to boot up my system with this ISO, it goes up to the CentOS blue screen and then the CAPS lock and Scroll Lock LEDs on the keyboard starts flashing. Then from here after, the system takes no input from keyboard and I have to power cycle it and it does the same thing. Could you get me any suggestion why this is causing and possible workaround. Thanks.

• Software that supports ATA Secure Erase Command

  - by vy32

  We have a lot of drives that need to be sanitized. NIST SP 800-88 recommends software that uses the ATA Secure Erase command. That's apparently the only way to be sure that the drive is properly wiped, due to bad-block remapping and such. I know that this functionality is available in hdparm. The problem with that approach is that it is inconsistent on multiple platforms, occasionally times out, doesn't have error-checking logic, and doesn't check the resulting drive to make sure that it has, in fact, been erased. So a proper program might use hdparm, but hdparm by itself isn't an answer. I'm looking for open source software that implements ATA Secure Erase. Ideally it will be a bootable disk image like DBAN, but it will use the ATA command.

• How Security Products Are Made; An Interview with BitDefender

  - by Jason Fitzpatrick

  Most of us use anti-virus and malware scanners, without giving the processes behind their construction and deployment much of a thought. Get an inside look at security product development with this BitDefender interview. Over at 7Tutorials they took a trip to the home offices of BitDefender for an interview with Catalin Co?oi–seen here–BitDefender’s Chief Security Researcher. While it’s notably BitDefender-centric, it’s also an interesting look at the methodology employed by a company specializing in virus/malware protection. Here’s an excerpt from the discussion about data gathering techniques: Honeypots are systems we distributed across our network, that act as victims. Their role is to look like vulnerable targets, which have valuable data on them. We monitor these honeypots continuously and collect all kinds of malware and information about black hat activities. Another thing we do, is broadcast fake e-mail addresses that are automatically collected by spammers from the Internet. Then, they use these addresses to distribute spam, malware or phishing e-mails. We collect all the messages we receive on these addresses, analyze them and extract the required data to update our products and keep our users secure and spam free.

• Alpha From PNGs Butchered

  - by ashes999

  I have a pretty vanilla Monogame game. I'm using PNG for all my sprites (made in Photoshop). I noticed that XNA is butchering the aliasing; no matter what I do, my graphics appear jaggedy. Below is a screenshot. The bottom half is what XNA shows me when I zoom in 2X using a Matrix on my GraphicsDevice (to make the effect more obvious). The top is when I pasted the same sprites from Photoshop and scaled them to 200%. Note that partially transparent pixels are turning whiteish. Is there a way to fix this? What am I doing wrong? Here's the relevant call to draw to the SpriteBatch: spriteBatch.Draw(this.texture, this.positionVector, null, Color.White, this.Angle, this.originVector, 1f, SpriteEffects.None, 0f); (this.positionVector can easily be Vector.Zero; Color.White as 100% alpha, I think; this.Angle can be a real angle (small > in the image) or zero (the orb itself).

Thanks for the help in advance.

• I want to version control my entire slice

  - by Tom

  I'm renting a slice (i.e., a VPS) from Slicehost. I've a spent a day or two filling up /usr with my favorite packages, /etc with configs and init scripts, and so on. Now I want to: save this whole setup somewhere (e.g., to load onto another machine). see what changes I've made to which files revert changes, tag revisions, and all that other good version control stuff Saving a disk image gives me (1), but not (2) and (3). Using Subversion (svn import / svn://someotherhost) might give me all three, but I expect problems if I actually try to check a project out into / and maintain .svn directories in root-owned areas. And to load my setup onto a fresh slice, I'd need to install an svn client on it first. Is there a good way to do what I want to do?

• Prevent Click Fraud in Advertisement system with PHP and Javascript

  - by CodeDevelopr

  I would like to build an Advertising project with PHP, MySQL, and Javascript. I am talking about something like... Google Adsense BuySellAds.com Any other advertising platform My question is mainly, what do I need to look out for to prevent people cheating the system and any other issues I may encounter? My design concept. An Advertisement is a record in the Database, when a page is loaded, using Javascript, it calls my server which in turn will use a PHP script to query the Database and get a random Advertisement. (It may do kore like get an ad based on demographics or other criteria as well) The PHP script will then return the Advertisement to the server/website that is calling it and show it on the page as an Image that will have a special tracking link. I will need to... Count all impressions (when the Advertisement is shown on the page) Count all clicks on the Advertisement link Count all Unique clicks on the Advertisement link My question is purely on the query and displaying of the Advertisement and nothing to do with the administration side. If there is ever money involved with my Advertisement buying/selling of adspace, then the stats need to be accurate and make sure people can't easily cheat the system. Is tracking IP address really the only way to try to prevent click fraud? I am hoping someone with some experience can clarify I am on the right track? As well as give me any advice, tips, or anything else I should know about doing something like this?

• Issues with Cinnamon?

  - by Corrodie

  I just recently switched my system over to Ubuntu 12.10, and decided on Cinnamon as my environment-- it all worked fine, at first. But I was poorly educated and started using Compiz and Emerald along with it--Setting both as replacements in startup processes. I now know, that's a big, big mistake. Now when loading Cinnamon, I am greeted to my background image, and only that. My only options seem to be to open a terminal. I was advised to attempt muffin --replace and mutter --replace Neither to any avail, the terminal closes, and I cannot load another one unless I completely reload. I went back to Unity, purged and autoremoved Cinnamon, emerald, and compizconfig, and attempted to reinstall Cinnamon, thinking that would solve the problem--no, it came back just as broken as before. So, I reinstalled ubuntu, then cinnamon---still broken. I'm assuming I must find a way to remove the replace commands-- but as I have no menu, I'm not positive I can do that. Is there any way I can access the startup processes via terminal? I'd think though, if I completely removed Cinnamon, all configurations would be gone too, so, it's just not making much sense. Is there some kind of reset I could possibly do? I've been browsing forums and questions here, all leading to things I'd already done, so, it can't hurt to ask for myself. I apologize if you would rather I have posted this over at mint. Next time, I will definitely check compatibility instead of assuming something just has to work. Any help is greatly appreciated, thanks! ****EDIT***** It seems although it didn't allow me to do it before, I was now allowed to access the settings and startup processes for Cinnamon via Unity, and, after quickly removing aforementioned processes- I'm up and running again.

• Upgrading Fedora 16 to 17 with crypted LVM

  - by nijansen

  As the title suggests, I want to upgrade Fedora 16 to the Fedora 17 Alpha build, but I am struggling to do so because of my crypted HDD. To avoid the hustle of CD-ROM or USB install, I thought the preupgrade would be a good idea. It downloads the stuff, stores an image somewhere and creates an entry in my boot manager. When I choose to upgrade from the boot manager it crashes halfway through because it can not access any of the prepared files (because it's crypted) and hands me a debug console. Unfortunately, this case apparently is not covered by the Fedora troubleshooting advice, at least I was not able to find anything there. I would guess I have to mount my HDD manually, but 1) how? and 2) how do I resume the upgrade afterwards? I would really appreciate a push in the right direction.

• Trouble Connecting to Virtual Machine after IP address Change

  - by David

  I have a VMware image running a copy of Fedora 11 which is hosted on a remote server. The remote server recently had its IP address change. I'm now unable to connect to my virtual machine. The server admin assures me that my virtual machine is running and assigned the new IP address. I have checked the firewalls and had the remote admin restart the VM instance. Neither of these fixed the problem. How do I troubleshoot a remote server which I am unable to SSH to? I'm actually even unable to ping the remote IP (connection timed out).

  I have installed CentOS 6 in Virtualbox. Although I have chosen to install General Purpose GNOME Desktop, the GNOME desktop does not start. All I get is a black and white text prompt. I would like to know how I can install GNOME Desktop from the CentOS DVD. How do I mount the DVD image? How do I install GNOME desktop from command line? If I already have the GNOME Desktop installed, why doesn't it start? How can I check from command line that I have GNOME installled? This virtual machine does not have internet connection, that's why I want to install the GNOME Desktop from DVD.

• How to get Visual Studio 2010 Express Edition on Windows 7

  - by thanigai

  Visual studio 2010 is an amzing release from Microsoft. I have tried the beta 1,2 of Visual Studio 2010 and finally the full version is released. I am also interested in the latest edition of Windows which nothing but our Windows 7. Next to Vista I like this version very much. Out of curiosity I have installed the prebuild version of Windows 7. I tried installing the express edition here and it failed making me disappointed. I tried two or three times and finally I decided to download the trial version of Windows 7. After that I can install the Visual Studio 2010 express edition easily. I have given the link below from where I have downloaded the file. http://www.microsoft.com/express/downloads/ Here the link give is through Web PI Installer. Other option is you can download the ISO image file and burn them to a disc or use a virtual disc This Visual Web developer will provide the Sql Server engine alone. To get a Sql Server Management Studio get from the following link http://www.microsoft.com/express/Database/InstallOptions.aspx That's it all the things necessary for the web application programming is ready. Ah I forget to tell about the Silverlight. Please find the Silverlight 4 latest tools from the below link (WCF RIA services is the main update) http://www.silverlight.net/getstarted/ Silverlight 4 Tools(http://www.microsoft.com/downloads/details.aspx?FamilyID=eff8a0da-0a4d-48e8-8366-6ddf2ecad801&displaylang=en) Expression Blend 4 trial(http://www.microsoft.com/downloads/details.aspx?FamilyID=88484825-1b3c-4e8c-8b14-b05d025e1541&displaylang=en) I think the reader would have enjoyed on how to get these things.

• What reasons are there to reduce the max-age of a logo to just 8 days? [closed]

  - by callum

  Most websites set max-age=31536000 (1 year) on the Cache-control headers of static assets such as logo images. Examples: YouTube Yahoo Twitter BBC But there is a notable exception: Google's logo has max-age=691200 (8 days). I've checked the headers on the Google logo in the past, and it definitely used to be 1 year. (Also, it used to be part of a sprite, and now it is a standalone logo image, but that's probably another question...) What could be valid technical reasons why they would want to reduce its cache lifetime to just 8 days? Google's homepage is one of the most carefully optimised pages in the world, so I imagine there's a good reason. Edit: Please make sure you understand these points before answering: Nobody uses short max-age lifetimes to allow modifying a static asset in future. When you modify it, you just serve it at a different URL. So no, it's nothing to do with Google doodles. Think about it: even if Google didn't understand this basic trick of HTTP, 8 days still wouldn't be appropriate, as only those users who don't have the original logo cached would see the doodle on doodle-day – and then that group of users would go on seeing the doodle for the following 8 days after Google changed it back :) Web servers do not worry about "filling up" the caches of clients (or proxies). The client manages this by itself – when it hits its own storage limit, it just starts dropping the lowest priority items to make space for new items. The priority score is based on the question "How likely am I to benefit from having cached this URL?", which is nothing to do with what max-age value the server sent when the URL was originally requested; it's a heuristic based on the "frecency" of requests for that URL. The max-age simply lets the server set a cut-off point – the time at which the client is supposed to discard the item regardless of how often it's being re-used. It would be very nice and trusting of a downstream client/proxy to rely on all origin servers "holding back" from filling up their caches, but I don't think we live in that world ;)

• Screen doesn't turn back on after resume on a Lenovo Thinkpad T420

  - by Wojtek

  Every time I suspend my notebook (Lenovo Thinkpad T420 - Intel HD graphic card) on Oneiric Ocelot 11.10 and turn it back on, the screen is black. The backlight is on and the system itself loads fine, but the display somehow doesn't get back. The first time after a fresh reboot the screen isn't black, it is mostly white/light-gray and it looks a bit like a distorted image. The pixels fade in until it gets almost completely light-gray. I've got a workaround for this: I switch to the first terminal (CTRL+ALT+F1) and back to X (CTRL+ALT+F7). In most cases that helps. Sometimes, when there's still a problem, I log in on the first terminal and run "unity --reset". Then go back to X - this helps always. I can tell that the system comes back, because I can log in with my fingerprint reader (or wait a bit and put in the password) "blindly", then do the workaround - I am logged in after the screen comes back. So it's only the display that is not working. Any help or advice where to look would be appreciated.

• how to create a mirror of minimum size to install Ubuntu

  - by Registered User

  I need to create an http url at my laptop to have a Ubuntu installation begin within my laptop on a Xen environment. This is how the final thing will look like http://bderzhavets.wordpress.com/2008/10/28/install-ubuntu-intrepid-server-pv-domu-at-xen-33-port-via-httpgetco-centos-52-dom0/ the host and client are both going to be my laptop, I Google d and came across apt-mirror and some other packages. I do not want to archive entire 15 GB Ubuntu repositories on my machine. It is not possible to use a CD,ISO,loop mounted disk (reason mentioned below). I have tried using netboot image on local machine which failed because if you are attempting to create a virtual machine on a hardware which does not support VT virt-manager installer necessarily needs a URL of this sort http://archive.ubuntu.com/ubuntu/dists/hardy/main/installer-i386/current/images/netboot/ any other option to create guest OS is simply grayed out. The unfortunate part is my Ethernet connections do not work when I boot with Xen-4.0 and a pv-ops Dom0 kernel from Jeremy's tree.Which is where I have to do this work.So I have to create a URL structure which is similar to Ubuntu mirrors.So how can I do this in bare minimum so that at least the console boots and once the console comes I can do some work.

• Progress bar in Super Hexagon using OpenGL ES 2 (Android)

  - by user16547

  I'm wondering how the progress bar in Super Hexagon was made. (see image, top left) Actually I am not very sure how to implement a progress bar at all using OpenGL ES 2 on Android, but I am asking specifically about the one used in Super Hexagon because it seems to me less straightforward / obvious than others: the bar changes its colour during game play. I think one possibility is to use the built-in Android progress bar. I can see from some Stackoverflow questions that you can change the default blue colour to whatever you want, but I'm not sure whether you can update it during the game play. The other possibility I can think of for implementing a progress bar is to have a small texture that starts with a scale of 0 and that you keep scaling until it reaches the maximum size, representing 100%. But this suffers from the same problem as before: you'll not be able to update the colour of the texture during run-time. It's fixed. So what's the best way to approach this problem? *I'm assuming he didn't use a particular library, although if he did, it would be interesting to know. I'm interested in a pure OpenGL ES 2 + Android solution.

• My iPhone is stuck at screen with USB cable and iTunes logo

  - by alex

  I just tried updating the iPhone's firmware, and things went haywire. iTunes informed the update had failed and linked me to this page. The iPhone is stuck on the image from the top of that page. I held down the sleep and home buttons until it turned off and turned it back on, and then went through the iPhone's 'restore' mode. It then error'd again and I'm stuck back with the logos on the iPhone. Does anyone know how to fix this? Thanks

• Windows Server 2008 R2 stuck at System Recovery Options

  - by Magnus

  One of my Windows Server 2008 R2 server has started to go into System Recovery Options at reboot. I have tried to let it go through a System Image Recovery, which it says completes successfully. But after reboot it again wants to do a system recovery. Safe mode doesn't work; it still wants to do a system recovery. Putting in the install DVD trying to do a repair actually brings up the very same System Revoery dialog again. Nothing has changed configuration wise. Any ideas?

• Black screen with thinkpad edge e525, AMD radeon HD before and after installation, plymouth?

  - by carolien

  I have a new thinkpad edge e525 (which should work) and wanted to try ubuntu (first linux experience). With the ubuntu desktop-cd I had a blackscreen before installation, I could fix that with nomodeset. After the installation, when rebooting I got the black screen again. First I see some ubuntu colour with a green busted stripe. I have the same problem with the live boot, also tried mint live, the stripe gets pink. I installed xubuntu 64bit from an alternate cd and I didnt have problems until de reboot after the installation. Same problem, just a black screen with the green stripe than blackscreen. I tried several things: adding nomodeset to the bootmenu, but than I get: No connection to plymouth and it is stuck at checking the battery status. I tried to replace quiet splash with text. Didnt work either. actually one time I saw a blue booting image before that. I managed to get a root command though via the recovery boot. I didnt dare to just remove the plymouth package. Can I just delete plymouth or do I have to deinstall it as described in several ways. (Problem is, right now the notebook doesnt have a internet connection. And I dont know how to manage it with a usb stick?) Or do I have to install the AMD catalyst driver manually? (Again, how can I do that with an usb stick) I also tried this: Ubuntu hits a black screen after boot. Is there any solution without internet? And if I need internet which is the right one? Please explain step by step what I have to write and so on! Thank you! also tried: set gfxpayload=text and: just remove splash and adding vesafb.nonsense=1 to the grub editor, because I couldnt find it anywhere

• Distribute Windows (XP or 7) as virtual appliance

  - by User32

  I'm looking at ways that may be possible to distribute a Microsoft Windows (e.g. 7) virtual appliance (such as VMWare image) pre-configured and installed with a large application of mine. Is this possible? If not, is it perhaps best to ask clients to perform a virtual appliance installation on their site and then install my application via a script of some sort? For these kinds of scenarios I see that open source OSes are heavily used, but in my case I cannot use Linux or any other open source OS due to some requirements.
