• Difference between bug, defect and flaw

  - by Hossein

  I was reading "Software Security: Building Security In" and in the first chapter I faced with 3 terms: bug, defect and flaw. The author gave a definition for each of them but I couldn't completely understand these. Can someone give me some examples for each term? What is a defect and what is a flaw? I think I know what bug is, a bug is a malfunction of a part of system which produces undesirable result, be it crashing on a wrong input or miscalculating a series of computations. Can someone elaborate more and correct me if I am wrong in this? UPDATE To be more precise in the book I mentioned above, they (the words) are presented in a way to make a distinction, that's why I am asking to know more. In that book there are some examples denoting which sample belongs to what and which category. For example: Buffer overflow is said to be a bug and issues in method overriding (subclassing issues) is being related to flaw category. Again race condition handling issues are considered bugs and Error-handling problems (fails open) are told to be flaws! I want more elaboration on these regards.

• What You Said: Where Do You Find Your Next Game?

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your favorite places and tricks for finding new video games to play. It turns out the least of your problems was finding new games! From the comments it became apparent How-To Geek readers had absolutely no problem finding new games to add to their gaming stable. Buzz writes: I have quite an elaborate procedure in finding my next game:For free games i simply follow the feeds on a few websites like Freegamer, LinuxGames, HappyPenguin and Penguspy. Every now and them i browse Wikipedia articles on free/FOSS games. For commercial games the procedure depends on what i enjoyed the most in that game:- If i enjoyed the story or the general feel: i usually start with a game i like and look for sequels, prequels, mods or spinoffs. I even go out on a limb and give other platforms (than a PC) a try, even if it usually means emulation. If you really enjoy a game series/saga it’s usually worth the effort.- If i enjoy the producer/gaming company then i seek out more of their games.- If i enjoy the technical achievements that went into making the game or if i am concerned for the system requirements of my gear i try to play games that are built on the same engine(s) as one of the games i ran smooth and enjoyed.- If i feel like playing a particular genre i usually start with a title i enjoyed and look for alternatives or similar games- You can always try searching for Game of The Year winners for a particular time period or other similar accomplishments.

• Looking for someone to point me in the right direction. I want to learn how to use hosted servers

  - by Leisure

  TL;DR: I want a Java program to run on a server, I want the server to forward a particular port from external to internal IP, I want store a few files on the server. Guides please. So I made a hack job Java program that acts as a server for my android application. It stores data in text files and HTML files, uploads them via FTP to my webhost, and manages socket connections (using port forwarding) with any phones connected. Right now I'm running it on NetBeans on my home computer. I know that it will probably slow down or crash once about 50 phones are connected at once. Is there any way I can run this program on a server with a high bandwidth? Can someone please find me a guide for that? I'm noob and don't know where to start looking. I seriously don't know anything about renting or using servers - I need a nice guide, and recommendations. My requirements for the server: Can handle about 2k socket connections at once Can run my Java code and store my txt files Can give me a port and an IP address so TCP/IP clients can be connected My budget: $50 CAD per month. Please someone set my ship sailing in the right direction, I really don't know where to look for resources.

• How to know currently open ports on the Windows Firewall?

  - by QIU Quan

  On Windows XP and Windows Server 2003, I can know currently open ports on the Windows Firewall using the following command: netsh firewall show state However, on Windows 7 and Hyper-V Server 2008 R2, when I give that command, it says: No ports are currently open on all network interfaces. IMPORTANT: Command executed successfully. However, "netsh firewall" is deprecated; use "netsh advfirewall firewall" instead. Apparently there are ports open because services such as NetBIOS NS, Remote Desktop, and Hyper-V remote administration are functioning. I tried a few 'netsh advfirewall' show commands, but didn't get a way to find out which ports are permit by Windows Firewall. Knowing the currently open ports, I can be sure that I'm permitting necessary and sufficient traffic to pass in, no more, no less. Going through the whole set of advanced firewall rules is so tedious and error-prone. Is there a command on Windows 7 and Windows Server 2008 to do this efficiently?

  Which is the code with which we can retreive alternative text of image: It is a Cataloge with clothes. Dressers, Shirts, Skirts e.t.c. in front page of a site. The featured images of the categories can be changed manually from someone. I did a check and it is asking me to give alt text. I did it to some images with alt="".

• Help me select a "Simpler" target to create a new language: .NET, LLVM, Go, Own VM

  - by mamcx

  Lets define "Simple". This is my first language. I have no previous experience I will not dedicate +4 years to learn it properly. I'm a professional software [developer], but as an amateur in this area, I want instant gratification. If the idea shows a future, I could rewrite it. I don't want to do everything from scratch. In fact, if there exists a way to get GO (for example), change its syntax, add some sugar, give some extra functions and leave intact everything else, that would be perfect! From the example of coffescript/scala I think is better to build on top of some rich runtime like .NET/GO so I don't need to rewrite everything. HOWEVER, if is better other way, no problem for the first try! I want it in a week. I need it in a week so it will really take a month. Then it truly takes 3 months. But I don't want to put more that 3 months on this. I could reduce the scope of my language, but I hope the tools will help me a lot... I want to build a new language. Similar to python, but typed. I wonder what to build it on top of. I like the idea of building on top of GO. To get their sane (IMHO) OO paradigm (I plan to do the same, using interfaces, not inheritance), get goroutines and some other stuff. In my naive thinking I imagine that spit another language could help me to debug it more easily. However, look like everyone is building on top of something like .NET (don't like Java), LLVM or make it own VM. I read http://createyourproglang.com/ (great!) and the part of the VM look "easy" to me. So, what I need is the proper criteria and question I need to know in advance to have a fair shot at make this.

• Live chat solutions

  - by Lèse majesté

  What good live chat/live help solutions are available (preferably for use on a site hosted on a LAMP stack and free)? I'm looking for a way to allow our sales and customer service reps to talk directly with visitors to our site. I've looked at phpopenchat, but it looks very unpolished. The only other free live chat app I've come across looked egregious. The aesthetics and UI design alone made me shudder to think what the underlying code might look like. This isn't a critical feature, and it wouldn't be hard to code up myself, so I'm not really looking for commercial software or paid services (unless there's a really compelling reason to use them). I'm just wondering if any other webmasters have come across a satisfactory free/open source solution for providing live customer support on their website. As a side note, live voice chat would also be an option, but it has to be be designed (or customizable) for customer support rather than a public chatroom. Edit: Looking at the responses, it looks like there probably aren't going to be many free solutions for this type of business-oriented chat solution, so feel free to post answers even if they are commercial solutions as long as they're a good value. Also feel free to post any alternate live support solutions (such as the Skype recommendation) that could be in someway integrated with a website. This will give me a good lay of the land for what people are actually using for live support, and I think will be more helpful to others reading this question.

• CentOS Default ACLs on Existing File System Objects

  - by macinjosh

  Is there a way to have existing file system objects inherit newly set default ACL settings of their parent directories? The reason I need to do this is that I have an user who connect via SFTP to my server. They are able to change directories in their FTP client and see the root folder and the rest of the server. They don't have permissions to change or edit anything but their own user directory but I would like to prevent them from even view the contents of other directories. Is there a better way to do this than ACLs? If ACLs are the way to go I'm assuming a default ACL on the root directory would be the best way to do restrict access. I could then selectively give the user permission to view certain directories. The problem is default ACLs are only inherited by new file system objects and not existing ones.

• Software design of a browser-based strategic MMO game

  - by Mehran

  I wonder if there are any known tested software designs for Travian-like browser-based strategic MMO games? I mean how would they implement the server of such games or what is stored in database and what is stored in RAM? Is the state of the world stored in one piece or is it distributed among a number of storage? Does anyone know a resource to study the problems and solutions of creating such games? [UPDATE] Suggested in comments, I'm going to give an example how would I design such a project. Even though I'm not sure if I'm proposing the right one. Having stored the world state in a MongoDB, I would implement an event collection in which all the changes to the world will register. Changes that are meant to happen in the future will come with an action date set to the future and those that are to be carried out immediately will be set to now. Having this datastore as the central point of the system, players will issue their actions as events inserted in datastore. At the other end of the system, I'll have a constant-running software taking out events out of the datastore which are due to be carried out and not done yet. Executing an event means apply some update on the world's state and thus the datastore. As scalable as this design sounds, I'm not sure if it will be worth implementing. For one, it is pointless to cache the datastore as most of updates happen once without any follow ups. For instance if you have the growth of resources in your game, you'll be updating the whole world state periodically in which case, having incorporated a cache, you are keeping the whole world in RAM (which most likely is impossible). So can someone come up with a better design?

• Light mask map and camera for static lights in XNA Platformer

  - by JiminyCricket

  Using the example for some basic light maps found here : http://blog.josack.com/2011/07/xna-2d-dynamic-lighting.html, I've managed to create a lightmap texture using individual lightmaps and display it over a 2D tiled world as in the Platformer example. I'm using the very basic 2D camera example as found here : http://www.david-amador.com/2009/10/xna-camera-2d-with-zoom-and-rotation/, and the problem is that the lightmap texture scrolls with the player sprite. This looks pretty good and would be excellent for lighting the player sprite as it moves. But, I also want to be able to place static lights (or some initial position for the lights) that do not move with the player or camera. When I turn off the camera or give it a static position, it works as a series of static lights so I believe it's probably caused by the camera transformation matrix following the player around. I'm using RenderTarget2Ds, one for the main game screen after all the backgrounds and tiles are rendered, and one for the "lightmap" which consists of a black background and a bunch of lighting textures which are merged with it using additive blending. For now, I'm doing all of this in PlatformerGame.cs where the camera transformation and position is set and the level.Draw() call is made. I can't figure out how to separate the drawing of the lightmap and the camera following the player. I was thinking it would be better to render the shadows and lighting directly in the drawing of the level itself, but I'm not sure how to do that either because this technique requires RenderTarget2Ds and calling SpriteBatch.Begin()/End().

• Digital audio does not work on MacBook Pro

  - by mathk

  I have a MacBook Pro (8,2). Using a TOSLINK cable I have no digital output. Oddly enough, sometime I can hear a glitch when I plug in the cable or when I give it a gentle wiggle. My guess is that the output is not correctly detecting that I have a digital link. So is there a way to force digital audio output on a MacBook Pro? Some say that in the Audio MIDI Setup there is an option but I can't find it. I am running OS X 10.7.5.

• Can Windows 7, Vista, or XP notify me after 30 minutes, or at 2:30pm?

  - by Jian Lin

  Come to think about it, since Windows 3.0, Windows 95, 2000, ME, XP, Vista, and Windows 7, does any Windows have a capability of giving a "beep beep" notification to me, let's say I need to go meet somebody after 30 minutes? Or give a "beep beep" at 2:30pm? I hope to hear some sound instead of a pop up window as I may be writing something on the desk instead of looking at the computer. I usually don't want to install 3rd party app for this purpose, as you never know what the app does or how trustworthy it is if it is not a popular app (like Firefox or Safari). Does any version of Windows come with that capability? I'd imagine it is an app that takes two days to write.

• How can I change the color of the pane separator for my Ambiance theme modification?

  - by WarriorIng64

  I am currently messing around with Ambiance, trying to give Nautilus a dark sidebar (because I think it looks much better that way, especially with the current look having the dark-colored breadcrumbs clashing horribly with the light-colored sidebar). I have zero experience and knowledge of how to create GTK+ themes, and I couldn't find any documentation online, so I just made a copy of the folder for Ambiance under /usr/share/themes, renamed it "Ambiance Dark Sidebar" and just started messing with color values. As shown below, I found the value in nautilus.css needed to be tweaked to create the dark sidebar, but there is still one part that stubbornly stays light gray. This is the pane separator, and I want to change it so it matches the rest better (marked in red). Does anyone know what I need to do to change the color of this part so it matches the rest of the sidebar better? I already know from seeing themes like Adwaita Dark that this should be possible, but even after poking around in that I didn't find anything that seemed to help. Here are the contents of the files I modified in the theme folder Ambiance Dark Sidebar, stored alongside Ambiance in /usr/share/themes: index.theme gtk-3.0/apps/nautilus.css

• Moving a VM from MS Virtual Server R2 to VirtualBox

  I have a Windows 2000 Professional VM happily running under MS Virtual Server R2 on WindowsXP. I need to move it to a different PC and the only one available is a Mac with VirtualBox on it. Theoretically, VirtualBox accepts .VHD files out of the box, but my attempts to run my VHD on VirtualBox resulted in failure. The Guest OS just keeps rebooting. I've attempted to get help on the VirtualBox forums, and they said that the VM image must first be prepped for the move, but could not give me any specifics. Anyone here know what is specifically involved in moving a Win2k .VHD to VirtualBox on the Mac?

• What's the best way to generate an NPC's face using web technologies?

  - by Vael Victus

  I'm in the process of creating a web app. I have many randomly-generated non-player characters in a database. I can pull a lot of information about them - their height, weight, down to eye color, hair color, and hair style. For this, I am solely interested in generating a graphical representation of the face. Currently the information is displayed with text in the nicest way possible, but I believe it's worth generating these faces for a more... human experience. Problem is, I'm not artist. I wouldn't mind commissioning an artist for this system, but I wouldn't know where to start. Were it 2007, I'd naturally think to myself that using Flash would be the best choice. I'd love to see "breathing" simulated. However, since Flash is on its way out, I'm not sure of a solid solution. With a previous game, I simply used layered .pngs to represent various aspects of the player's body: their armor, the face, the skin color. However, these solutions weren't very dynamic and felt very amateur. I can't go deep into this project feeling like that's an inferior way to present these faces, and I'm certain there's a better way. Can anyone give some suggestion on how to pull this off well?

• GPL - what is distribution?

  - by Martin Beckett

  An interesting point came up on another thread about alleged misappropriation of a GPL project. In this case the enterprise software was used by some large companies who essentially took the code, changed the name, removed the GPL notices and used the result. The point was - if the company did this and only used the software internally then there isn't any distribution and that's perfectly legal under GPL. Modifications by their own employees for internal use would also be allowed. So At what point does it become a distribution? Presumably if they brought in outside contractors under 'work for hire' their modifications would also be internal and so not a distribution. If they hired an external software outfit to do modifications and those changes were only used internally by the company - would those changes be distributed? Does the GPL apply to the client or to the external developers? If the company then give the result to another department, another business unit, another company? What if the other company is a wholly owned subsidiary? ps. yes I know the answer is ask a lawyer. But all the discussion I have seen over GPL2/GPL3 distribution has been about webservices - not about internal use.

• Dealing with an Idiot [closed]

  - by inspectorG4dget

  I'm a 4th year University Computer Science student, and I have this problem, that I don't seem to be able to find a straight answer to: As a 4th year computer science student, I spend more time in the computer lab on campus, than even my own home. This means that getting along with everyone else here is very important to me. In most cases, this is not an issue because my interactions with almost all the people here fall into one of the following categories: Let me help you, junior Hi fellow student in a course I'm taking, I'm having trouble with this assignment question. Can you give me a hint as to how you solved it? Hi fellow student in a course I'm taking, This is how I solved the problem that you're stuck on. Hope it helps Hi fellow student, I noticed that you're working on a project, using a library that I'm interested in. Can we setup a time so I can learn about this library from you? This model of interaction works very well for me. However, there is one fellow student, who manages to make my life hell beyond all of this (his name is not important, let's just call him "Sam"). He seems to be always (pardon my crass description) high and completely unwilling to contribute to a constructive, academic conversation. He's a pretty smart guy, but just comes across as (I hate to say something like this about a fellow student, but) an imbecile. He also has ignorant opinions on important topics, some of which pertain to my specialization (AI, NLP, etc), and when I try to explain to him why he's wrong, all he does is insult me and put me in a foul mood. I have tried ignoring him (sitting somewhere else in the lab, headphones, etc), but he seems to like doing this because he approaches me and no amount of "leave me alone" seems to do the trick. Can anyone please suggest to me how to deal with this man in a civil way? Thank you

• Installing nvidia drivers causes computer to boot to command prompt.
