  • XNA Notes 008

    - by George Clingerman
    This week has been a rough one. I’ve been sick and then in some kind of slump for my afternoon coding sessions. It could be from the cold, could be I’m still tired from writing that Windows Phone 7 game development book (which is out now!) or it could just be I’m tired of winter and want some sunshine.

  • Rendering Linear Gradients using the HTML5 Canvas

    - by dwahlin
    Related HTML5 Canvas Posts: Getting Started with the HTML5 Canvas Rendering Text with the HTML5 Canvas Creating a Line Chart using the HTML5 Canvas New Pluralsight Course: HTML5 Canvas Fundamentals Gradients are everywhere. They’re used to enhance toolbars or buttons and help add additional flare to a web page when used appropriately. In the past we’ve always had to rely on images to render gradients which works well, but isn’t necessarily the most efficient (although 1 pixel wide images do work well). CSS3 provides a great way to render gradients in modern browsers (see http://www.colorzilla.com/gradient-editor for a nice online gradient generator tool) but it’s not the only option. If you’re working with charts, games, multimedia or other HTML5 Canvas applications you can also use gradients and render them on the client-side without relying on images. In this post I’ll introduce how to use linear gradients and discuss the different functions that can be used to create them.   Creating Linear Gradients Linear gradients can be created using the 2D context’s createLinearGradient function. The function takes the starting x,y coordinates and ending x,y coordinates of the gradient:   createLinearGradient(x1, y1, x2, y2);   By changing the start and end coordinates you can control the direction that the gradient renders. For example, adding the following coordinates causes the gradient to render from left to right since the y value stays at 0 for both points while the x value changes from 0 to 200. var lgrad = ctx.createLinearGradient(0, 0, 200, 0); Here’s an example of how changing the coordinates affects the gradient direction:   Once a linear gradient object has been created you can set color stops using the addColorStop() function. It takes the location where the color should appear in the gradient with 0 being the beginning and 1 being at the end (0.5 would be in the middle) as well as the color to display in the gradient. lgrad.addColorStop(0, 'white'); lgrad.addColorStop(1, 'gray');   An example of combining createLinearGradient() with addColorStop() is shown next:   Using createLinearGradient() var canvas = document.getElementById('myCanvas'); var ctx = canvas.getContext('2d'); var lgrad = ctx.createLinearGradient(0, 0, 200, 0); lgrad.addColorStop(0, 'white'); lgrad.addColorStop(1, 'gray'); ctx.fillStyle = lgrad; ctx.fillRect(0, 0, 200, 200); ctx.strokeRect(0, 0, 200, 200); This code renders a white to gray gradient as shown next: A live example of using createLinearGradient() is shown next. Click the Result tab to see the code in action.   In the next post on the HTML5 Canvas I’ll take a look at radial gradients and how they can be used. In the meantime, if you’re interested in learning more about the HTML5 Canvas and how it can be used in your Web or Windows 8 applications, check out my HTML5 Canvas Fundamentals course from Pluralsight. It has over 4 1/2 hours of canvas goodness packed in it.

  • upgraded "Compiz' and "Unity", now no Unity 3D on screen

    - by user18432
    Today when I logged in to my Ubuntu 12.04, the update manager told me of some upgrades. Compiz and Unity were in those upgrades. After I installed the upgrades, I can no longer get the Unity panel on the left side of screen or the systray at the top of screen. I now have to run Ubuntu 12.04 with Unity 2D. My laptop is a HP Pavilion dv9000 with Nvidia GeForce Go 7600 video. I tried to run "unity --reset" but it says there are serious issues with compiz.

  • Unreal Tournament 3 vs UDK: What Should I Choose?

    - by Matt Christian
    Many people in the mod community were very excited to see the release of the Unreal Developer Kit (UDK) a few months ago.  Along with generating excitement into a very dedicated community, it also introduced many new modders into a flourishing area of indie-development.  However, since UDK is free, most beginners jump right into UDK, which is OK though you might just benefit more from purchasing a shelf-copy of Unreal Tournament 3. UDK UDK is a free full version of UnrealEd (the editor environment used to create games like Gears of War 1/2, Bioshock 1/2, and of course Unreal Tournament 3).  The editor gives you all the features of the editor from the shelf-copy of the game plus some refinements in many of the tools.  (One of the first things you'll find about UnrealEd is that it's a collection of tools grouped into the same editor so it really isn't a single 'tool') Interestingly enough, Epic is allowing you to sell any game made in UDK with a few catches.  First off, you must purchase a liscense for your game (which, I THINK is aproximately $99 starting).  Secondly, you must pay 25% of all profits for the first $5,000 of your game revenue to them (about $1250).  Finally, you cannot use any of the 'media' provided in UDK for your game.  UDK provides sample meshes, textures, materials, sounds, and other sample pieces of media pulled (mostly) from Unreal Tournament 3. The final point here will really determine whether you should use UDK.  There is a very small amount of media provided in UDK for someone to go in and begin creating levels without first developing your own meshes, textures, and other media.  Sure, you can slap together a few unique levels, though you will end up finding yourself restriced to the same items over and over and over.  This is absolutely how professional game development is; you are 'given' (typically liscensed or built in-house) an engine/editor and you begin creating all the content for the game and placing it.  UDK is aimed toward those who really want to build their game content from scratch with a currently existing engine.  It is not suited for someone who would like to simply build levels and quick mods without learning external 3D programs and image editing software. Unreal Tournament 3 Unless you have a serious grudge against FPS's, Epic, or your computer sucks, there really is no reason not to own this game for PC.  You can pick it up on Steam or Amazon for around $20 brand new.  Not only are you provided with a full single-player and multiplayer game, but you are given the entire UnrealEd 3.0 including all of the content used to build UT3.  If you want to start building levels and mods quickly for UT3, you should absolutely pick up a shelf-copy. However, as off-the-shelf UT3 is a few years old now, the tools have not been updated for quite a while.  Compared to UDK, the menus are more difficult to navigate through and take more time getting used to.  Since UDK is updated almost every month, there are new inclusions to the editor that may not be in UT3 (including the future addition of 3D!).  I haven't worked enough with shelf UT3 to see if there are more features in UDK or if they both feature the same stuff in different forms, however you should remember that the Unreal Engine 3.0 has undergone numerous upgrades between it's launch and Gears of War 2 (in fact, Epic had a conference to show off what changed just between the Gears of Wars games). Since UT3 has much more core content, someone who wants to focus on level editing or modding the core UT3 game may find their needs better suited with an off-the-shelf copy of UT3.  If that level designer has a team that is generating custom assets, they may be better off with UDK. The choice is now yours...

  • What Counts For A DBA: ESP

    - by Louis Davidson
    Now I don’t want to get religious here, and I’m not going to, but what I’m going to describe in this ‘What Counts for a DBA’ installment sometimes feels like magic. Often  I will spend hours thinking about the solution to a design issue or coding problem, working diligently to try to come up with a solution and then finally just give up with the feeling that I’m not even qualified to be a data entry clerk, much less a data architect.  At this point I often take a walk (or sometimes a nap), and then it hits me. I realize that I have the answer just sitting in my brain, ready to implement.  This phenomenon is not limited to walks either; it can happen almost any time after I stop my obsession about a problem. I call this phenomena ESP (or Extra-Sensory Programming.)  Another term for this could be ‘sleeping on it’, and while the idiom tends to mean to let time pass to actively think about a problem, sleeping on a problem also lets you relax and let your brain do the work. I first noticed this back in my college days when I would play video games for hours on end. We would get stuck deep in some dungeon unable to find a way out, playing for days on end until we were beaten down tired. Once we gave up and walked away, the solution would usually be there waiting for one of us before we came back to play the next day.  Sometimes it would be in the form of a dream, and sometimes it would just be that the problem was now easy to solve when we started to play again.  While it worked great for video games, it never occurred when I studied English Literature for hours on end, or even when I worked for the same sort of frustrating hours attempting to solve a homework problem in Calculus.  I believe that the difference was that I was passionate about the video game, and certainly far less so about homework where people used the word “thou” instead of “you” or x to represent a number. This phenomenon occurs somewhat more often in my current work as a professional data programmer, because I am very passionate about SQL and love those aspects of my career choice.  Every day that I get to draw a new data model to solve a customer issue, or write a complex SELECT statement to ferret out the answer to a complex data question, is a great day. I hope it is the same for any reader of this blog.  But, unfortunately, while the day on a whole is great, a heck of a lot of noise is generated in work life. There are the typical project deadlines, along with the requisite project manager sitting on your shoulders shouting slogans to try to make you to go faster: Add in office politics, and the occasional family issues that permeate the mind, and you lose the ability to think deeply about any problem, not to mention occasionally forgetting your own name.  These office realities coupled with a difficult SQL problem staring at you from your widescreen monitor will slowly suck the life force out of your body, making it seem impossible to solve the problem This is when the walk starts; or a nap. Maybe you hide from the madness under your desk like George Costanza hides from Steinbrenner on Seinfeld.  Forget about the problem. Free your mind from the insanity of the problem and your surroundings. Then let your training and education deep in your brain take over and see if it will passively do the rest for you. If you don’t end up with a solution, the worst case scenario is that you have a bit of exercise or rest, and you won’t have heard the phrase “better is the enemy of good enough” even once…which certainly will do your brain some good. Once you stop expecting whipping your brain for information, inspiration may just strike and instead of a humdrum solution you find a solution you hadn’t even considered, almost magically. So, my beloved manager, next time you have an urgent deadline and you come across me taking a nap, creep away quietly because I’m working, doing some extra-sensory programming.

  • Graduate Life in Oracle by Ramakrishna Nalabothula

    - by david.talamelli
    Preparation for the BIG interview: I prepared in both technical and logical aspects to face the Oracle Interview. I had to cover almost all main areas in technical and many types of problems in logical areas. We attended mock- interviews and written tests at our college, browsed websites and communities. Having started with such a rigorous preparation before Oracle visited the college; it was possible for me to make it into the list of final selection. I put in a big effort to reach this position and I am very happy to achieve this. Why I chose Oracle: Oracle is one of the best technology providers and has a large customer base. I think it is not an easy job to offer services to that many customers. So, the company needs young and dynamic people and I wanted to be one among them. This gave me spirit and led me to walk into Oracle. I am working on different technologies and learning something new in the field. Having many customers is challenging Oracle and my work is challenging me. I am confident enough that customers to both me and Oracle will never lose their faith. Learning at Oracle: The style of learning is good and never resembles a classroom session in a college. It is always fun to learn here. There is no exam to track the performance. There is enough time until we completely learn it. There is no concept of stiff competition. Peers help through KT (Knowledge Transfers) and there are good resources in the Oracle to learn. People are always there to direct you to those. There are lots of opportunities for Web learning too! My Work Area: My team gives me a great opportunity to offer service to the entire product. There were no situations when I got tense with my work or targets and deliverables. I work with a Global Team and my manager is based in the UK. I have a lot of freedom and flexibility. I use the work from home option in case of any disturbances in the city or due to personal problems. I have a weekly meeting with my manager and use Instant Messenger for status updates. My manager plans very well to give me enough time to complete tasks. I have good coordination from the team towards our deadlines. My work has also brought me close to many people across various technology and product teams. I am glad to make many friends across Oracle. I am enjoying my time and work here. I cover all the major activities in the team. I am thankful to everyone from the Development and Quality Assurance Team to have high confidence in me by assigning such big responsibilities. Primary tasks are maintaining the environments that are very unstable at times. This really requires big time and effort to trace the root causes. I am working and still learning on all these areas. The happiest thing is I got chances to travel to USA & UK for training and for supporting a few customer demo projects. I have got to explore more across two countries and got sponsored to visit the places around due to Oracle's policies. I am very much thankful for these what I have from Oracle and for the cooperation there from other colleagues. Fun at Work: Oracle has a club from Employees to conduct games and events. I had an opportunity to participate in competitions, tournaments inside Oracle and Inter-Corporate for all games. I thank Oracle for providing me all these opportunities and I would like to extend my thanks to Senior Management for their confidence in me. I thank Oracle HR Recruiting Team too for selecting me into Oracle and giving me this opportunity to share my experience and feelings. Ramakrishna Nalabothula

  • Node.js Lockstep Multiplayer Architecture

    - by Wakaka
    Background I'm using the lockstep model for a multiplayer Node.js/Socket.IO game in a client-server architecture. User input (mouse or keypress) is parsed into commands like 'attack' and 'move' on the client, which are sent to the server and scheduled to be executed on a certain tick. This is in contrast to sending state data to clients, which I don't wish to use due to bandwidth issues. Each tick, the server will send the list of commands on that tick (possibly empty) to each client. The server and all clients will then process the commands and simulate that tick in exactly the same way. With Node.js this is actually quite simple due to possibility of code sharing between server and client. I'll just put the deterministic simulator in the /shared folder which can be run by both server and client. The server simulation is required so that there is an authoritative version of the simulation which clients cannot alter. Problem Now, the game has many entity classes, like Unit, Item, Tree etc. Entities are created in the simulator. However, for each class, it has some methods that are shared and some that are client-specific. For instance, the Unit class has addHp method which is shared. It also has methods like getSprite (gets the image of the entity), isVisible (checks if unit can be seen by the client), onDeathInClient (does a bunch of stuff when it dies only on the client like adding announcements) and isMyUnit (quick function to check if the client owns the unit). Up till now, I have been piling all the client functions into the shared Unit class, and adding a this.game.isServer() check when necessary. For instance, when the unit dies, it will call if (!this.game.isServer()) { this.onDeathInClient(); }. This approach has worked pretty fine so far, in terms of functionality. But as the codebase grew bigger, this style of coding seems a little strange. Firstly, the client code is clearly not shared, and yet is placed under the /shared folder. Secondly, client-specific variables for each entity are also instantiated on the server entity (like unit.sprite) and can run into problems when the server cannot instantiate the variable (it doesn't have Image class like on browsers). So my question is, is there a better way to organize the client code, or is this a common way of doing things for lockstep multiplayer games? I can think of a possible workaround, but it does have its own problems. Possible workaround (with problems) I could use Javascript mixins that are only added when in a browser. Thus, in the /shared/unit.js file in the /shared folder, I would have this code at the end: if (typeof exports !== 'undefined') module.exports = Unit; else mixin(Unit, LocalUnit); Then I would have /client/localunit.js store an object LocalUnit of client-side methods for Unit. Now, I already have a publish-subscribe system in place for events in the simulator. To remove the this.game.isServer() checks, I could publish entity-specific events whenever I want the client to do something. For instance, I would do this.publish('Death') in /shared/unit.js and do this.subscribe('Death', this.onDeathInClient) in /client/localunit.js. But this would make the simulator's event listeners list on the server and the client different. Now if I want to clear all subscribed events only from the shared simulator, I can't. Of course, it is possible to create two event subscription systems - one client-specific and one shared - but now the publish() method would have to do if (!this.game.isServer()) { this.publishOnClient(event); }. All in all, the workaround off the top of my head seems pretty complicated for something as simple as separating the client and shared code. Thus, I wonder if there is an established and simpler method for better code organization, hopefully specific to Node.js games.

Edit: Okay, so I found the wireless card by using lspci -vvv and it returned this: 0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) Subsystem: Dell Wireless 1397 WLAN Mini-Card Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast TAbort- SERR- Kernel modules: ssb lsmod Module Size Used by dm_crypt 22528 0 joydev 17393 0 dell_wmi 12601 0 sparse_keymap 13658 1 dell_wmi dell_laptop 13671 0 dcdbas 14098 1 dell_laptop psmouse 72919 0 uvcvideo 67203 0 serio_raw 13027 0 videodev 86588 1 uvcvideo snd_hda_codec_idt 60251 1 mac_hid 13077 0 snd_hda_intel 32765 5 snd_hda_codec 109562 2 snd_hda_codec_idt,snd_hda_intel snd_hwdep 13276 1 snd_hda_codec parport_pc 32114 0 rfcomm 38139 0 bnep 17830 2 ppdev 12849 0 snd_pcm 80845 3 snd_hda_intel,snd_hda_codec bluetooth 158438 10 rfcomm,bnep snd_seq_midi 13132 0 snd_rawmidi 25424 1 snd_seq_midi snd_seq_midi_event 14475 1 snd_seq_midi snd_seq 51567 2 snd_seq_midi,snd_seq_midi_event snd_timer 28931 2 snd_pcm,snd_seq snd_seq_device 14172 3 snd_seq_midi,snd_rawmidi,snd_seq binfmt_misc 17292 1 snd 62064 18 snd_hda_codec_idt,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device soundcore 14635 1 snd snd_page_alloc 14108 2 snd_hda_intel,snd_pcm lp 17455 0 parport 40930 3 parport_pc,ppdev,lp sky2 53628 0 ums_realtek 17920 0 uas 17699 0 i915 414603 3 wmi 18744 1 dell_wmi drm_kms_helper 45466 1 i915 drm 197692 4 i915,drm_kms_helper i2c_algo_bit 13199 1 i915 video 19068 1 i915 usb_storage 39646 1 ums_realtek ifconfig -a eth0 Link encap:Ethernet HWaddr 00:23:ae:24:71:45 inet addr:192.168.1.158 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::223:aeff:fe24:7145/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:14340 errors:0 dropped:0 overruns:0 frame:0 TX packets:10191 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:15403754 (15.4 MB) TX bytes:1262570 (1.2 MB) Interrupt:18 ham0 Link encap:Ethernet HWaddr 7a:79:05:2d:b0:f7 inet addr:5.45.176.247 Bcast:5.255.255.255 Mask:255.0.0.0 inet6 addr: fe80::7879:5ff:fe2d:b0f7/64 Scope:Link inet6 addr: 2620:9b::52d:b0f7/96 Scope:Global UP BROADCAST RUNNING MULTICAST MTU:1404 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:179 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:0 (0.0 B) TX bytes:27480 (27.4 KB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:433 errors:0 dropped:0 overruns:0 frame:0 TX packets:433 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:60051 (60.0 KB) TX bytes:60051 (60.0 KB) iwconfig lo no wireless extensions. ham0 no wireless extensions. eth0 no wireless extensions. the results for sudo lshw -class network *-network description: Wireless interface product: BCM4312 802.11b/g LP-PHY vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:0c:00.0 logical name: eth1 version: 01 serial: 00:22:5f:77:1f:e6 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=wl0 driverversion=5.100.82.38 latency=0 multicast=yes wireless=IEEE 802.11bg resources: irq:17 memory:f69fc000-f69fffff *-network description: Ethernet interface product: 88E8040 PCI-E Fast Ethernet Controller vendor: Marvell Technology Group Ltd. physical id: 0 bus info: pci@0000:09:00.0 logical name: eth0 version: 13 serial: 00:23:ae:24:71:45 size: 100Mbit/s capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=sky2 driverversion=1.30 duplex=full firmware=N/A ip=192.168.1.158 latency=0 link=yes multicast=yes port=twisted pair speed=100Mbit/s resources: irq:45 memory:f68fc000-f68fffff ioport:de00(size=256) *-network description: Ethernet interface physical id: 2 logical name: ham0 serial: 7a:79:05:2d:b0:f7 size: 10Mbit/s capabilities: ethernet physical configuration: autonegotiation=off broadcast=yes driver=tun driverversion=1.6 duplex=full firmware=N/A ip=5.45.176.247 link=yes multicast=yes port=twisted pair speed=10Mbit/s and the results of rfkill list all 0: brcmwl-0: Wireless LAN Soft blocked: yes Hard blocked: yes 1: dell-wifi: Wireless LAN Soft blocked: yes Hard blocked: yes

  • Fresh Ubuntu Install - Grub not loading

    - by Ryan Sharp
    System Ubuntu 12.04 64-bit Windows 7 SP1 Samsung 64GB SSD - OS' Samsung 1TB HDD - Games, /Home, Swap WD 300'ishGB HDD - Backup Okay, so I'm very frustrated, so please excuse me if I miss anything out as my head is clouded by anger and impatience, etc. I'll try me best, though. First of all, I'll explain how I got to my predicament. I finally got my new SSD. I firstly installed Windows, which completed without a hitch. Afterwards, I tried to install Ubuntu, which failed several times due to problems irrelevant to this question, but I mention this to explain my frustrations, sorry. Anyway, I finally installed Ubuntu. However, I chose the 'bootloader' to be installed on the same partition as where I was installing the Ubuntu Root partition, as that was what I believed to be the best choice. It was of my thinking that it was supposed to go on the same partition and on the SSD, which is my OS drive, though with my problem, it apparently was wrong. So I tried to fix it by checking guides and following their directions, but seemed to have messed it up even more. Here is what I receive after I use the fdisk -l command: (I also added explanations for which I used each partition for) Disk /dev/sda: 64.0 GB, 64023257088 bytes 255 heads, 63 sectors/track, 7783 cylinders, total 125045424 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x324971d1 Device Boot Start End Blocks Id System /dev/sda1 * 2048 206847 102400 7 HPFS/NTFS/exFAT /dev/sda2 208896 48957439 24374272 7 HPFS/NTFS/exFAT /dev/sda3 48959486 125044735 38042625 5 Extended /dev/sda5 48959488 125044735 38042624 83 Linux sda1 --/ Windows Recovery sda2 --/ Windows 7 sda3/5 --/ Ubuntu root [ / ] Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xc0ee6a69 Device Boot Start End Blocks Id System /dev/sdb1 1024208894 1953523711 464657409 5 Extended /dev/sdb3 * 2048 1024206847 512102400 7 HPFS/NTFS/exFAT /dev/sdb5 1024208896 1939851263 457821184 83 Linux /dev/sdb6 1939853312 1953523711 6835200 82 Linux swap / Solaris sdb3 --/ Partition for Steam games, etc. sdb5 --/ Ubuntu Home [ /home ] sdb6 --/ Ubuntu Swap Partition table entries are not in disk order Disk /dev/sdc: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x292eee23 Device Boot Start End Blocks Id System /dev/sdc1 2048 625141759 312569856 7 HPFS/NTFS/exFAT sdc1 --/ Generic backup I also used a Boot Script that other users suggested, so that I can give more details on my partitions and also where Grub is located... ============================= Boot Info Summary: =============================== => Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of the same hard drive for core.img. core.img is at this location and looks for (,msdos5)/boot/grub on this drive. => Grub2 (v1.99) is installed in the MBR of /dev/sdb and looks at sector 1 of the same hard drive for core.img. core.img is at this location and looks for (,msdos5)/boot/grub on this drive. => Windows is installed in the MBR of /dev/sdc. Now that is weird... Why would Grub2 be installed on both my SSD and HDD? Even weirder is why is Windows on the MBR of my backup hard drive? Nothing I did should have done that... Anyway, here is the entire Output from that script... PASTEBIN So, to summarize what I need: How can I fix my setup so grub loads on startup? How can I clean my partitions to remove unnecessary grubs? What did I do wrong so that I don't do something so daft again? Thank you so much for reading, and I hope you can help me. I've been trying to have a successful setup since Friday, and I'm almost at the point that I'm really tempted to throw my computer out the window due to my frustration.

  • User password rejected on login screen but accepted on text console login

    - by MadsirR
    I had to force shutdown my Ubuntu 12.04 64-bit, after which I restarted and tried to log in as a normal user, which was rejected several times. I then logged in as guest and tty to my regular account with use of my normal password, which succeeded. (So the password is still valid.) How can I gain access again via the normal login procedure (welcome screen)? Update: When I tried to log on with my new password, it again was denied. When I deliberately tried to log on with a faulty password, an error message came back, saying: Access denied - wrong password. I suppose, the first time the password was not rejected, but the procedure was aborted for some reason. Some additional info after trying to find a solution: I am conviced it is a Compiz-issue. Why? before this happened, all sessions came to a grinding halt, regardless of being logged on in a 2D or 3d environment. I found a link saying that I should remove Compiz and proceed in a 2D environment, which initiall worked without a glitch, until my system went into a state of total obivium. Only after that, the above mentioned troubles appeared. In the meantime I have happened to find a thread with reference 17381, describing exactly what I have experienced. For now, I will try to cure this situation (later this week) and revert with the results, hopefully to close this post. In the meantime I cordially thank you all, even if you didn't kill the problem; you gave me the inspiration to look further and find a possible cure. Update2: After 15 hrs of trial-and-error I callled it quits (When I decided to tackle this problem, I've given myself 12 hrs, to avoid massive loss of time.) I decided to re-install Precise, since the "point 1" version has become availabe. Log-in is back to normal, as is the graphic environment. Response to mouse input is stil appalling, especially when I have a series of screens open as "children"of a "parent" screen. It still completely locks up. I have installed Enlightenment, Gnome classic, Gnome 3, Cinnamon and they all behave in a similar fashion. FOR THOSE WHO NEED A WAY-OUT IN SITUATIONS OF THE LIKE: Open a terminal with [Ctrl+Alt+F2]. Type [sudo killall Firefox] (or whatever application you wish to terminate). Key in your password. Return to your graphical screen with [Ctrl+Alt+F7], and Bob's your uncle. Just re-open Firefox like nothing happened. Next time you are stuck: [Ctrl+Alt+F2], upward arrow till you meet the command of your desire, [Ctrl+Alt+F7], etcetera. Hope this is of help. My next move will be to upgrade the kernel to 3.4 from the repositories for 12.10. However, since this entails a totally new situation, I will start a new thread on this site to avoid topic pollution I will keep you posted. Still.

  • Seeking advice on tools and technology for my new game [closed]

    - by k.k. slider
    I'm a C# developer who has been programming a game in my spare time using XNA and Visual Studio. The game's logic is mostly done and I've completed a prototype that has most of the functionality of (what I envision to be) the final game. However, having heard about the uncertain future and (possibly) limited audience for XNA games, I'm looking to switch platforms... but I don't know what technology would best suit my needs. Below are some specifics about my game and what exactly I'm looking for, if you're interested: The game is a 2D turn-based tactical RPG (strategy game) for two players. It is a basic sprite and tile based game with animations and sound. 3D capabilities are not necessary. I'd like to allow players to compete with others online, and have a basic ranking/matchmaking system. I will probably need something that can interact with a server and a database (the game is turn-based and has no RNG, so cheating would be easy to detect even if most computation is done client-side and minimal data is sent to the server). Ideally, I would be able to release an early version of the game and have people give feedback as I develop additional features (similar to Minecraft). I'd prefer to have a way to release periodic updates to the game instead of releasing an absolute final product. To reach the widest possible audience, I'd prefer technology that allows me to release on PC, Android, iOS, and (maybe) Mac. This is a game with simple mouse inputs which can fit on a mobile touch screen. The game should be monetizable. If I find success with this game, then I may consider becoming a full-time indie game developer. I have several other game ideas and have learned quite a bit from my first attempt at game development. My first thought was an F2P/microtransaction model, but I'm open to other suggestions. Language isn't a primary concern of mine, since I have a decent amount of experience using several languages to program large projects. I'm willing to spend money (e.g. on a developer's license), but the more expensive it gets, the more hesitant I am to use it. I've looked into the following solutions... there are a LOT of tools out there... if anyone has experience with any of these and would like to recommend/reject any of them, it would be helpful. C#/.NET (XNA/MonoGame/SDL/SlimDX/Xamarin/ExEn/ANX?) HTML5/JS (AppMobi/PhoneGap/Marmalade/FlashCanvas/Cordova/libRocket?) Python (Pyglet/Pygame/Kivy?) Java (JavaFX/libGDX?) Unity/Construct 2/Cocos2D/NME/Corona/other game creation software? I'd like something that can do 2D and isn't limited by being too high-level. Other languages (Lua/LOVE? Moai?) Thanks for answering this rather long and tedious question...

  • DirectX particle system. ConstantBuffer

    - by Liuka
    I'm new in DirectX and I'm making a 2D game. I want to use a particle system to simulate a 3D starfield, so each star has to set its own constant buffer for the vertexshader es. to set it's world matrix. So if i have 500 stars (that move every frame) i need to call 500 times VSsetconstantbuffer, and map/unmap each buffer. with 500 stars i have an average of 220 fps and that's quite good. My bottelneck is Vs/PsSetconstantbuffer. If i dont call this function i have 400 fps(obliviously nothing is display, since i dont set the position of the stars). So is there a method to speed up the render of the particle system?? Ps. I'm using intel integrate graphic (hd 2000-3000). with a nvidia (or amd) gpu will i have the same bottleneck?? If, for example, i dont call setshaderresource i have 10-20 fps more (for 500 objcets), that is not 180.Why does SetConstantBuffer take so long?? LPVOID VSdataPtr = VSmappedResource.pData; memcpy(VSdataPtr, VSdata, CszVSdata); context->Unmap(VertexBuffer, 0); result = context->Map(PixelBuffer, 0, D3D11_MAP_WRITE_DISCARD, 0, &PSmappedResource); if (FAILED(result)) { outputResult.OutputErrorMessage(TITLE, L"Cannot map the PixelBuffer", &result, OUTPUT_ERROR_FILE); return; } LPVOID PSdataPtr = PSmappedResource.pData; memcpy(PSdataPtr, PSdata, CszPSdata); context->Unmap(PixelBuffer, 0); context->VSSetConstantBuffers(0, 1, &VertexBuffer); context->PSSetConstantBuffers(0, 1, &PixelBuffer); this update and set the buffer. It's part of the render method of a sprite class that contains a the vertex buffer and the texture to apply to the quads(it's a 2d game) too. I have an array of 500 stars (sprite setup with a star texture). Every frame: clear back buffer; draw the array of stars; present the backbuffer; draw also call the function update( which calculate the position of the sprite on screen based on a "camera class") Ok, create a vertex buffer with the vertices of each quads(stars) seems to be good, since the stars don't change their "virtual" position; so.... In a particle system (where particles move) it's better to have all the object in only one vertices array, rather then an array of different sprite/object in order to update all the vertices' position with a single setbuffer call. In this case i have to use a dynamic vertex buffer with the vertices positions like this: verticesForQuad={{ XMFLOAT3((float)halfDImensions.x-1+pos.x, (float)halfDImensions.y-1+pos.y, 1.0f), XMFLOAT2(1.0f, 0.0f) }, { XMFLOAT3((float)halfDImensions.x-1+pos.x, -(float)halfDImensions.y-1+pos.y, 1.0f), XMFLOAT2(1.0f, 1.0f) }, { XMFLOAT3(-(float)halfDImensions.x-1+pos.x, (float)halfDImensions.y-1.pos.y, 1.0f), XMFLOAT2(0.0f, 0.0f) }, { XMFLOAT3(-(float)halfDImensions.x-1.pos.x, -(float)halfDImensions.y-1+pos.y, 1.0f), XMFLOAT2(0.0f, 1.0f) }, ....other quads} where halfDimensions is the halfsize in pixel of a texture and pos the virtual position of a star. than create an array of verticesForQuad and create the vertex buffer ZeroMemory(&vertexDesc, sizeof(vertexDesc)); vertexDesc.Usage = D3D11_USAGE_DEFAULT; vertexDesc.BindFlags = D3D11_BIND_VERTEX_BUFFER; vertexDesc.ByteWidth = sizeof(VertexType)* 4*numStars; ZeroMemory(&resourceData, sizeof(resourceData)); resourceData.pSysMem = verticesForQuad; result = device->CreateBuffer(&vertexDesc, &resourceData, &CvertexBuffer); and call each frame Context->IASetVertexBuffers(0, 1, &CvertexBuffer, &stride, &offset); But if i want to add and remove obj i have to recreate the buffer each time, havent i?? There is a faster way? I think i can create a vertex buffer with a max size (es. 10000 objs) and when i update it set only the 250 position (for 250 onjs for example) and pass this number as the vertexCount to the draw function (numObjs*4), or i'm worng

  • XNA vs SlimDX for offscreen renderer

    - by Groky
    Hello, I realise there are numerous questions on here asking about choosing between XNA and SlimDX, but these all relate to game programming. A little background: I have an application that renders scenes from XML descriptions. Currently I am using WPF 3D and this mostly works, except that WPF has no way to render scenes offscreen (i.e. on a server, without displaying them in a window), and also rendering to a bitmap causes WPF to fallback to software rendering. So I'm faced with having to write my own renderer. Here are the requirements: Mix of 3D and 2D elements. Relatively few elements per scene (tens of meshes, tens of 2D elements). Large scenes (up to 3000px square for print). Only a single frame will be rendered (i.e. FPS is not an issue). Opacity masks. Pixel shaders. Software fallback (servers may or may not have a decent gfx card). Possibility of being rendered offscreen. As you can see it's pretty simple stuff and WPF can manage it quite nicely except for the not-being-able-to-export-the-scene problem. In particular I don't need many of the things usually needed in game development. So bearing that in mind, would you choose XNA or SlimDX? The non-rendering portion of the code is already written in C#, so want to stick with that.

  • [SOLVED] BitmapFactory.decodeStream returning null when options are set.

I've read some good guides, but none using .decodeStream. Here httpIM:NOT//nornalbion.SPAMcom/blog/?p=143 httpIM:NOT//kfb-android.blogspot.SPAMcom/2009/04/image-processing-in-android.html WORKS JUST FINE InputStream is = connection.getInputStream(); Bitmap img = BitmapFactory.decodeStream(is, null, options); DOESNT WORK InputStream is = connection.getInputStream(); Options options = new BitmapFactory.Options(); options.inJustDecodeBounds = true; BitmapFactory.decodeStream(is, null, options); Boolean scaleByHeight = Math.abs(options.outHeight - TARGET_HEIGHT) >= Math.abs(options.outWidth - TARGET_WIDTH); if(options.outHeight * options.outWidth * 2 >= 200*100*2){ // Load, scaling to smallest power of 2 that'll get it <= desired dimensions double sampleSize = scaleByHeight ? options.outHeight / TARGET_HEIGHT : options.outWidth / TARGET_WIDTH; options.inSampleSize = (int)Math.pow(2d, Math.floor( Math.log(sampleSize)/Math.log(2d))); System.out.println("Samplesize: " + options.inSampleSize); } // Do the actual decoding options.inJustDecodeBounds = false; //options.inTempStorage = new byte[IMG_BUFFER_LEN]; Bitmap img = BitmapFactory.decodeStream(is, null, options);

  • bug with varargs and overloading?

    - by pstanton
    There seems to be a bug in the Java varargs implementation. Java can't distinguish the appropriate type when a method is overloaded with different types of vararg parameters. It gives me an error The method ... is ambiguous for the type ... Consider the following code: public class Test { public static void main(String[] args) throws Throwable { doit(new int[]{1, 2}); // <- no problem doit(new double[]{1.2, 2.2}); // <- no problem doit(1.2f, 2.2f); // <- no problem doit(1.2d, 2.2d); // <- no problem doit(1, 2); // <- The method doit(double[]) is ambiguous for the type Test } public static void doit(double... ds) { System.out.println("doubles"); } public static void doit(int... is) { System.out.println("ints"); } } the docs say: "Generally speaking, you should not overload a varargs method, or it will be difficult for programmers to figure out which overloading gets called." however they don't mention this error, and it's not the programmers that are finding it difficult, it's the compiler. thoughts?

  • Resources related to data-mining and gaming on social networks

    - by darren
    Hi all I'm interested in the problem of patterning mining among players of social networking games. For example detecting cheaters of a game, given a company's user database. So far I have been following the usual recipe for a data mining project: construct a data warehouse that aggregates significant information select a classifier, and train it with a subsectio of records from the warehouse validate classifier with another test set lather, rinse, repeat Surprisingly, I've found very little in this area regarding literature, best practices, etc. I am hoping to crowdsource the information gathering problem here. Specifically what I'm looking for: What classifiers have worked will for this type of pattern mining (it seems highly temporal, users playing games, users receiving rewards, users transferring prizes etc). Are there any highly agreed upon attributes specific to social networking / gaming data? What is a practical amount of information that should be considered? One problem I've run into is data overload, where queries and data cleansing may take days to complete. Related to point above, what hardware resources are required to produce results? I've found it difficult to estimate the amount of computing power I will require for production use. It has become apparent that a white box in the corner does not have enough horse-power for such a project. Are companies generally resorting to cloud solutions? Are they buying clusters? Basically, any resources (theoretical, academic, or practical) about implementing a social networking / gaming pattern-mining program would be very much appreciated. Thanks.
