  • Young C++ student lacking direction

    - by ephaitch
    I was hoping for some direction or guidance regarding my C++ learning experience. I have now read two books, from cover to cover, twice. The first was Ivor Horton's Beginning Visual C++ 2010 and Starting out with C++ Early Objects (7th Edition). At this point and after several months I feel like all I know how to do in C++ is create a basic class, define some methods, use the STL, and read and write info to and from the console buffer (cin/cout). But simple things like saving data to a file, reading from a file, printing, connecting to an FTP site, doing some basic graphic manipulation on the screen (not even DirectX/OpenGL), and so-on I can't do or don't even know where to start. I feel I still haven't learned C++ thoroughly. I think you guys get where I'm going with this. I tried downloading SFML and compiling it in Visual C++ 2010 Professional. After quite a bit of time, I got it, but then I was lost. I followed the tutorials and one didn't work. I kept getting an error regarding a missing symbol and after an hour or so on Google, I couldn't figure it out. Can anyone point me in a direction of where one goes from here? I would imagine others have been at this point sometime during their early days.

  • Examples of 2D side-scrollers that achieve open non-linear feel?

    - by Milosz Falinski
    I'm working on a 2.5D platformer prototype that aims for an open feel while maintaining familiar core mechanics. Now, there's some obvious challenges with creating a non constricted feel in a spatially constricted environment. What I'm interested in, is examples of how game designers deal with the "here's a level, beat the bad guys/puzzles to get to the next level" design that seems so natural to most platformers (eg. Mario/Braid/Pid/Meat Boy to name a few). Some ideas for achieving openness I've come across include: One obvious successful example is Terraria, which achieves openness simply through complexity and flexibility of the game-system Another example that comes to mind is Cave Story. Game is non-linear, offers multiple choices and side-stories Mario, Rayman and some other 'classics' with a top-down level selection. I actually really dislike this as it never did anything for me emotionally and just seems like a bit of a lazy way to do things. Note: I've not actually had much experience with most of the 'classical' console platformers, apart from the obvious Marios/Zeldas/Metroids, since I've grown up on adventure games. By that I mean, it's entirely possible that I simply missed some games that solve the problem really well and are by some considered obvious 'classics'.

  • How do I send email with sendmail to external hosts?

    - by Jake
    If I wanted to send an email to a user on the same linux machine, I can run: echo -e "Subject: Foo\n\nBar\n" | sendmail -v jacob But if I run: echo -e "Subject: Foo\n\nBar\n" | sendmail -v [email protected] It will give me the error: 050 >>> MAIL From:<jacob@mu> SIZE=321 050 550 5.1.8 Cannot resolve your domain {mx-us011} If my machine has access to the internet but is behind a router and has no domain associated with it, can I use sendmail to send mail to this address? Do I need to connect through an SMTP server? Can I do that with sendmail? If I use sendmail's -f option and put my gmail account there it will work. Can (or should I) I use my IP address? echo -e "Subject: Foo\n\nBar\n" | sendmail -v -f [email protected] [email protected] I'm a bit lost on how all this comes together in sending mail from the command line.

  • wmic output well formed xml on remote queries

    - by Mervin
    I want to use the WMI command line tool (wmic) to get information about windows computers on the network and output it as valid xml. However, I can't seem to find the right way to do this as the outputted xml currently contains invalid tokens for which I think I should use the /TRANSLATE:basicxml switch. The command: wmic /NODE:"tech-demo" /IMPLEVEL:Impersonate /USER:MyUser /PASSWORD:MyPassword /PRIVILEGES:DISABLE /AUTHLEVEL:Pkt /AUTHORITY:"ntlmdomain:companydomain.local" PATH Win32_LogicalDisk GET * /FORMAT:rawxml This command runs but returns invalid xml tokens ('<' and '' I think? edit: it appears to fail parsing at ‹) When I add the translate switch I get the message: Can not use credentials for local connections a bit strange that it tries to query the local pc when I add the switch.. Help would be greatly appreciated.

  • Is it bad practice for services to share a database in SOA?

    - by Paul T Davies
    I have recently been reading Hohpe and Woolf's Enterprise Integration Patterns, some of Thomas Erl's books on SOA and watching various videos and podcasts by Udi Dahan et al. on CQRS and Event Driven systems. Systems in my place of work suffer from high coupling. Although each system theoretically has its own database, there is a lot of joining between them. In practice this means there is one huge database that all systems use. For example, there is one table of customer data. Much of what I've read seems to suggest denormalising data so that each system uses only its database, and any updates to one system are propagated to all the others using messaging. I thought this was one of the ways of enforcing the boundaries in SOA - each service should have its own database, but then I read this: http://stackoverflow.com/questions/4019902/soa-joining-data-across-multiple-services and it suggests this is the wrong thing to do. Segregating the databases does seem like a good way of decoupling systems, but now I'm a bit confused. Is this a good route to take? Is it ever recommended that you should segregate a database on, say an SOA service, an DDD Bounded context, an application, etc?

  • What electronic user-story-mapping tools can you recommend?

    - by azheglov
    Agile software development relies heavily on a work item type called user stories. For example, you have a backlog full of user stories and you can select a few of them to work on during the next sprint. But where and how do you find user stories to put into the backlog? There is a popular technique for doing that called story mapping. Jeff Patton invented it and here is the definitive guide on how to do it. The question is, what electronic tools are out there that support Patton's story-mapping technique? I've done a bit of research, found Pivotal and Rally plug-ins (but I'm not a customer of either) and I'm currently experimenting with SilverStories. What other tools are out there? What have you used? What do you (not) recommend? Why? UPDATE: Some people who wrote comments seem to lean towards an answer that applying this technique is simply impossible with an electronic tool and we should just accept that. Can't someone write it up as an answer?

  • Apache keeps resetting while testing on localhost...

    Hello everyone. I'm getting errors while testing web pages on localhost. I'm running Windows 7 64-bit. I'm not using Wamp or Xampp. This is what the error.log tells me (I've highlighted the errors in question): [Sat Mar 06 05:10:55 2010] [notice] Apache/2.2.14 (Win32) PHP/5.2.13 configured -- resuming normal operations [Sat Mar 06 05:10:55 2010] [notice] Server built: Sep 28 2009 22:41:08 [Sat Mar 06 05:10:55 2010] [notice] Parent: Created child process 6588 httpd.exe: Could not reliably determine the server's fully qualified domain name, using 192.168.2.2 for ServerName httpd.exe: Could not reliably determine the server's fully qualified domain name, using 192.168.2.2 for ServerName [Sat Mar 06 05:10:55 2010] [notice] Child 6588: Child process is running [Sat Mar 06 05:10:55 2010] [notice] Child 6588: Acquired the start mutex.

  • When is meta description still relevant?

    - by Jeff Atwood
    I received this bit of advice about the meta description tag recently: Meta descriptions are used by Google probably 80% of the time for the snippet. They don’t help with rankings but you should probably use them. You could just auto generate them from the first part of the question. The description tag exists in the header, like so: <meta name="Description" content="A brief summary of the content on the page."> I'm not sure why we would need this field, as Google seems perfectly capable of showing the relevant search terms in context in the search result pages, like so (I searched for c# list performance): In other words, where would a meta description summary improve these results? We want the page to show context around the actual search hits, not a random summary we inserted! Google Webmaster Central has this advice: For some sites, like news media sources, generating an accurate and unique description for each page is easy: since each article is hand-written, it takes minimal effort to also add a one-sentence description. For larger database-driven sites, like product aggregators, hand-written descriptions are more difficult. In the latter case, though, programmatic generation of the descriptions can be appropriate and is encouraged -- just make sure that your descriptions are not "spammy." Good descriptions are human-readable and diverse, as we talked about in the first point above. The page-specific data we mentioned in the second point is a good candidate for programmatic generation. I'm struggling to think of any scenario when I would want the Google-generated summary, that is, actual context from the page for the search terms, to be replaced by a hard-coded meta description summary of the question itself.

  • Introducing Programming To a Mathematician

    - by ell
    I currently am a programmer, I'm almost 16 years of age and have pretty much narrowed my careers down to something involving a Computer Science degree or Electrical Engineering degree (I know they are quite different but this question is about my friend) but my friend isn't so sure. He is very interested in maths and is very good at it and I think he would enjoy programming but he isn't willing to try it (edit he is willing to try but has never done before). Can anyone give me an suggestions for a language or tool that he could dabble in programming (at a reasonably basic level I assume) to solve maths problems or involve some kind of maths. As I say he enjoys maths a lot but I think he would enjoy programming, the problem is I don't want him to be put off by the stuff that isn't relevant at introductory levels such as memory allocation et al. I know that is very important but the point is that I want him to learn a bit of programming with maths then hopefully if he is interested enough he can start learning programming as programming. Thanks in advance, ell. Edit: Its not that he's completely uninterested - more that he hasn't actively explored the area before, maybe because he isn't informed about it. I wouldn't want to force him to do something he doesn't want to, I see this as more of a little push so that he can learn about programming. If he doesn't like it - fair enough, I can't control that and don't want to but if he turns out to enjoy it - this push will have been the right thing.

  • Turning off Chrome's visual effects

    - by Wesley
    Is there any way to turn off the visual effects used by Google Chrome? For example, the tabs slide around smoothly, the scrolling is really smooth, and there is a huge arrow that fades in and out during download. Reason why I'd like to know is primarily because I want to maximize battery life on my netbook by using less visual effects and, secondly, because I use Chrome on slower systems and would like to maximize the performance and efficiency of Chrome. This applies mainly to Windows XP, but also Vista, 7 and even (X)Ubuntu 9.10. EDIT1: Oh yes... disabling the attaching/detaching of tabs and turning them into translucent in the process. That's a bit stressful on my slower machines.

  • MVVM - child windows and data contexts

    - by GlenH7
    Should a child window have it's own data context (View-Model) or use the data context of the parent? More broadly, should each View have its own View-Model? Are there are any rules to guide making that decision? What if the various View-Models will be accessing the same Model? I haven't been able to find any consistent guidance on my question. The MS definition of MVVM appears to be silent on child windows. For one example, I have created a warning message notification View. It really didn't need a data context since it was passed the message to display. But if I needed to fancy it up a bit, I would have tapped the parent's data context. I have run into another scenario that needs a child window and is more complicated than the notification box. The parent's View-Model is already getting cluttered, so I had planned on generating a dedicated VM for the child window. But I can't find any guidance on whether this is a good idea or what the potential consequences may be. FWIW, I happen to be working in Silverlight, but I don't know that this question is strictly a Silverlight issue.

  • Windows 2008 R2 Server Core Disk Space Requirements/Recomendations

    - by Richard West
    I'm in the preparation stage to roll out a few Windows 2008 R2 Server Core in my VMware ESX environment. In looking over the documentation it looks like Server Core can operate in a little as 6.5 GB of hard drive space. Less disk space required. A Server Core installation requires only about 3.5 gigabytes (GB) of disk space to install and approximately 3 GB for operations after the installation. I am curious as to anyone’s real world experience and recommendations with regard to this requirement. Is it realistic? A little bit about our environment: Less than 25 users, and around 75 computers/servers in our current AD system. These systems will be responsible for normal AD operations and print servers for 5 printers - nothing to big here.

  • RPi and Java Embedded GPIO: Using Java to read input

    - by hinkmond
    Now that we've learned about using Java code to control the output of the Raspberry Pi GPIO ports (by lighting up LEDs from a Java app on the RPi for now and noting in the future the same Java code can be used to drive industrial automation or medical equipment, etc.), let's move on to learn about reading input from the RPi GPIO using Java code. As before, we need to start out with the necessary hardware. For this exercise we will connect a Static Electricity Detector to the RPi GPIO port and read the value of that sensor using Java code. The circuit we'll use is from William J. Beaty and is described at this Web link. See: Static Electricity Detector He calls it an "Electric Charge" detector, which is a bit misleading. A Field Effect Transistor is subject to nearby electro-magnetic fields, such as a static charge on a nearby object, not really an electric charge. So, this sensor will detect static electricity (or ghosts if you are into paranormal activity ). Take a look at the circuit and in the next blog posts we'll step through how to connect it to the GPIO port of your RPi and then how to write Java code to access this fun sensor. Hinkmond

  • Ubuntu installation on iMac

    - by Shanew
    I have an iMac configured as follows - Screen 27" CPU 3.4 GHz i7 Graphics AMD Radeon HD 6970 1024 MB I downloaded Ubuntu version 11.10 64 bit ISO and burnt that to both DVD and USB stick as per the instructions on Ubuntu's download page. Neither will boot. Symptoms are as follows - DVD: When the iMac is restarted and booted from DVD (labelled Windows which isn't mentioned in Ubuntu's website instructions) one line is displayed against a black screen displaying a message about the developer and date. After 5 minutes the message hangs and the DVD ceases to spin. USB Stick: Strangely I have to select the EFI boot CD icon which appears after holding down the Alt key. A text menu appears offering me to try Ubuntu without installing. I select this and the screen goes blank and stays blank. Any ideas? Lastly, after writing Ubuntu to DVD and USB stick, neither could be read by OSX making the instructions to eject them as per Ubuntu website's instructions useless. This might help? Thanks, Shane.

  • Any good C++ Component/Entity frameworks?

    - by Pat
    (Skip to the bold if you want to get straight to my question :) ) I've been dabbling in the different technologies available out there to use. I tried Unity and component based design, managing to get a little guy up and running around a map with basic pathfinding. I really loved how easy it was to program using components, but I wanted a bit more control and something more 2D friendly, so I went with LibGDX. I looked around and found 2 good frameworks for Java, which are Artemis and Apollo. I didn't like Artemis much, so I went with Apollo, which I loved. I managed to integrate it with Box2D and get a little guy running around bouncing balls. Great! But since I want to try out most of the options, there is still C++/SFML that I haven't tried yet. Coming from a Java/C# background, I've always wanted to get my hands dirty with C++. But then, after some looking around, I noticed there aren't any Component-Based frameworks for me to use. There's a somewhat done porting of Artemis, but, aside from not being completely finished, I didn't quite like Artemis even in Java. I found Apollo's approach much more.. logical. So, my question is, are there any good Component/Entity frameworks for C++ that I can use that are similar to Artemis, or preferably, Apollo?

  • Getting Xbox Live via a wired network with my laptop that has internet access wirelessly

    - by Alex Franco
    I'm running the latest version (as of yesterday anyways) of Ubuntu Desktop 64bit, but installed on my laptop if it makes a difference. I had Windows 7 preinstalled when i bought it and it worked fine with the wireless from my house and bridging the connection with a LAN to my xbox for Live. Now with Ubuntu I tried the same setup, but I'm unfamiliar with Ubuntu so I didn't get far. Best I got so far is wireless internet on my laptop and a wired connection to the xbox that continually connects and disconnects. Heres my network settings. if theres fields not included its because theyre empty on mine or theyre my MAC address or network password Wireless Network 1 settings: Connect Automatically: Checked. Available to all Users: Checked Wireless: SSID: Franco's Mode: Infrastructure MTU: Automatic IPv4 Settings: Method: Automatic (DHCP) IPv6 Settings: Method: Automatic Wired Network 1: Connect Automatically: Checked Available to all Users: Checked Wired: MTU: Automatic IPv4 Settings: Method: Automatic (DHCP) IPv6 Settings: Method: Automatic Any help would be greatly appreciated. EDIT: 6:26pm It seems to be staying connected now. Doing the Network test on my xbox it pickups the network, but cannot detect any PC. Restarting the Xbox, however, leaves my computer unable to connect bringing up the Wire Network disconnected 'blip' every minute or so again. Before I had restarted the Xbox it said "Connected 100 MB/s". Now it only says "connecting". I did have my computer and xbox on in this Wired Network Disconnected blip cycle for a long period of time so it may have finally connected, just without the ability to detect my laptop. I left for 2 hours or so in the middle of typing up the original question. I finished posting this when i got back and then tried to mess with it a bit again, in case youre wondering why i didnt include this before... I've said too much. Forgive my long-winded fingers :p

  • Send an Email at a future date

    - by Ryan
    I'd like to write up an email that gets sent out in a few days. I'd prefer to use Gmail, but I could use some other client if necessary. It doesn't look like Gmail has this feature in their labs anywhere, but it could just be hiding somewhere. Any ideas? EDIT: a bit more backstory on my particular situation. My wife is out of town for three weeks, and I've decided to email her every day while she's out. Unfortunately, I myself am going camping this weekend, so I wanted to pre-record a message that gets sent while I'm out. Unfortunately, FutureMail and FutureMe both are for sending email to yourself, probably for anti-spam reasons. I guess the best solution is to use thunderbird on my laptop (so it's shielded from power outages). Seems a little excessive to keep a computer running just to send a few emails, but whatever gets the job done :).

  • Bad 3D Performance in Ubuntu 12.04

    - by Pandem
    I already posted a question before but I didn't really get any advice/help. I'll be a bit more brief/general in hope it'll help. I have an MSI HD 7850 with the Catalyst 12.4 drivers installed. I've found that I'm having bad 3D performance for some reason but I'm not entirely sure what. I suspect it may just that the graphics card is new and AMD just need to work on their drivers but it would be nice to get advice and narrow the problem down so that I can be sure rather than wait for driver updates that may not even help. I ran gxlgears to give some general idea of how bad the performance is. At default size it is averaging around 2000 FPS. The command glxinfo confirms the renderer is using AMD Radeon HD 7800 Series with OpenGL version 4.2. Edits below: As asked for others: lspci -v output is here. fglrxinfo output is here xvinfo output is here glxinfo | grep rendering says yes for direct rendering. These confirmed that everything was configured correctly. Within Unity and Gnome Classic: glxgears had an FPS of around 2000 FPS fgl_glxgears had an FPS of around 544 FPS Within LDXE: glxgears had an FPS of around 4600 FPS fgl_glxgears had an FPS of around 1600 FPS In the end it was discovered that Compiz was causing a large performance decrease and solution was simply to change window manager for the time being. Thanks to TechZilla for all his help!

  • Burning Xvid and Dvix Files problems

    - by chobo2
    Hi I am using windows 7 ultimate 64 bit edition and Nero 8. Recently I noticed that every time I go to nero and burn a dvix/xvid file as a data DVD and try to play it in a dvd player that supports these types it does not load up and play. I then go to my XP machine with Nero 6 on it and burn the exact same file as a data DVD and it works in the exact same dvd player. I am not sure why this is happening? I am not sure if it is windows 7, nero 8 or my actual dvd burner that is the problem. How should I go about and figure out what the problem is? Thanks

  • Dealing with 2D pixel shaders and SpriteBatches in XNA 4.0 component-object game engine?

    - by DaveStance
    I've got a bit of experience with shaders in general, having implemented a couple, very simple, 3D fragment and vertex shaders in OpenGL/WebGL in the past. Currently, I'm working on a 2D game engine in XNA 4.0 and I'm struggling with the process of integrating per-object and full-scene shaders in my current architecture. I'm using a component-entity design, wherein my "Entities" are merely collections of components that are acted upon by discreet system managers (SpatialProvider, SceneProvider, etc). In the context of this question, my draw call looks something like this: SceneProvider::Draw(GameTime) calls... ComponentManager::Draw(GameTime, SpriteBatch) which calls (on each drawable component) DrawnComponent::Draw(GameTime, SpriteBatch) The SpriteBatch is set up, with the default SpriteBatch shader, in the SceneProvider class just before it tells the ComponentManager to start rendering the scene. From my understanding, if a component needs to use a special shader to draw itself, it must do the following when it's Draw(GameTime, SpriteBatch) method is invoked: public void Draw(GameTime gameTime, SpriteBatch spriteBatch) { spriteBatch.End(); spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.AlphaBlend, null, null, null, EffectShader, ViewMatrix); // Draw things here that are shaded by the "EffectShader." spriteBatch.End(); spriteBatch.Begin(/* same settings that were set by SceneProvider to ensure the rest of the scene is rendered normally */); } My question is, having been told that numerous calls to SpriteBatch.Begin() and SpriteBatch.End() within a single frame was terrible for performance, is there a better way to do this? Is there a way to instruct the currently running SpriteBatch to simply change the Effect shader it is using for this particular draw call and then switch it back before the function ends?

  • Using HTML5 Today part 2&ndash;Fixing Semantic tags with a Shiv

    - by Steve Albers
    Semantic elements and the Shiv! This is the second entry in the series of demos from the “Using HTML5 Today” talk. For the definitive discussion on unknown elements and the HTML5 Shiv check out Mark Pilgrim’s Dive Into HTML5 online book at http://diveintohtml5.info/semantics.html#unknown-elements Semantic tags increase the meaning and maintainability of your markup, help make your page more computer-readable, and can even provide opportunities for libraries that are written to automagically enhance content using standard tags like <nav>, <header>,  or <footer>. Legacy IE issues However, new HTML5 tags get mangled in IE browsers prior to version 9.  To see this in action, consider this bit of HTML code which includes the new <article> and <header> elements: Viewing this page using the IE9 developer tools (F12) we see that the browser correctly models the hierarchy of tags listed above: But if we switch to IE8 Browser Mode in developer tools things go bad: Did you know that a closing tag could close itself?? The browser loses the hierarchy & closes all of the new tags.  The new tags become unusable and the page structure falls apart. Additionally block-level elements lose their block status, appearing as inline.    The Fix (good) The block-level issue can be resolved by using CSS styling.  Below we set the article, header, and footer tags as block tags. article, header, footer {display:block;} You can avoid the unknown element issue by creating a version of the element in JavaScript before the actual HTML5 tag appears on the page: <script> document.createElement("article"); document.createElement("header"); document.createElement("footer"); </script> The Fix (better) Rather than adding your own JS you can take advantage of a standard JS library such as Remy Sharp’s HTML5 Shiv at http://code.google.com/p/html5shiv/.  By default the Modernizr library includes HTML5 Shiv, so you don’t need to include the shiv code separately if you are using Modernizr.

  • Graphing services using pnp4nagios

    - by Matias
    Hi! I've managed to install pnp4nagios 0.6.3 and I'm a bit confused about how pnp4nagios generates graphics. Almost out of the box, it started graphs for ping and some http servers (not all of them). But, how can I make it graph things like disk utilization (When that value comes from SNMP)?? For example, ls /usr/local/pnp4nagios/var/perfdata/isis/ Cola_de_Mail.rrd Cola_de_Mail.xml HTTP.rrd HTTP.xml PING.rrd PING.xml Those are checks running on the host isis, but there are many other checks for that server that are not taken into account by pnp4nagios. How can I make pnp4nagios "see" the other checks?? Thanks!

  • I need something substantial to do [on hold]

    - by Christian Delapena
    I'm a 19 year old computer geek who was recently exposed to Linux. I know quite a bit of it now and would like to do something substantial with it. I've visited websites like openhatch where you can get started on opensource projects but I'm more interested in something Linux-specific like hosting a website or tracking some important operation. Maybe running a script that will give me data on something important. I don't know. I'm essentially bored and I want to put my knowledge and love of Linux to good use.

  • HP Envy 14, Ubuntu 10.10 and trouble with the graphics cards

    - by Carsten Gehling
    A few days ago I bought a HP Envy 14, containing 2 graphics card: An integrated Intel graphics card, and an ATI HD 5650. I've installed Ubuntu 10.10 32-bit on the machine. Most things work fine out of the box, but the graphics cards are giving me trouble. When booting, I get the message "failed to get i915 symbols, graphics turbo disabled". Then the screen blanks out during the remaining boot period. I am able to get the display working by changing to one of the consoles, then closing and opening the laptop's lid. It seems that Ubuntu gets confused about which card to use. I've read here: http://www.andreas-demmer.de/en/2010/07/18/testbericht-linux-auf-dem-hp-envy-14 that I should be able to turn off one the cards by echoing keywords into /sys/kernel/debug/vgaswitcheroo/switch, but that path is not available on my system. The BIOS does not have any methods to switch of the ATI card. Help anyone? /Carsten
