• How to connect externally to local network from local network?

  - by ventrilobug

  I have this weird problem with a Ventrilo server software running in my linux machine. If I connect the server inside my local network, messages keep lagging etc. But users joining the server outside my network do not experience any problems. So the question is, how can I trick the software inside the local network to make me appear as joining from external network. Do I need some proxy running in some external network machine? Does someone offer this kind of service? All the problems started when I changed my router so I guess it has something to do with the new router, but I haven't found a solution by changing settings in my router so I try to fix this in some other way.

• Which Graphics/Geometry abstraction to choose?

  - by Robz

  I've been thinking about the design for a browser app on the HTML5 canvas that simulates a 2D robot zooming around, sensing the world around it. I decided to do this from scratch just for fun. I need shapes, like polygons, circles, and lines in order to model the robot and the world it lives in. These shapes need to be drawn with different appearance attributes, like border/fill style/width/color. I also need to have geometry functions to detect intersections and containment for the robot's sensors and so that the robot doesn't go inside stuff. One idea for functions is to have two totally separate libraries, one to implement graphics (like drawShape(context, shape)) and one for geometry operations (like shapeIntersectsShape(shape1, shape2)). Or, in a more object-oriented approach, the shape objects themselves could implement methods to do their own graphics (shape.draw(context)) and geometry operations (shape1.intersects(shape2)). Then there is the data itself: whether the data to draw a shape and the data to do geometric operations on that shape should be encapsulated within the same object, or be separate structures (where one would contain the other, or both be contained inside another structure). How do existing applications that do graphics/geometry stuff deal with this? Is there one model that is best, or is each good for certain applications? Should the fact that I'm using Javascript instead of a more classical language change how I approach the design?

• Using screen, commands like less and man don't clear the screen afterwards

  - by Boldewyn

  In contrast to this question I want the clearing of the screen re-enabled for less. It works fine in my xterm terminal under Cygwin/mintty or Gnome Terminal (both xterms). However, when inside a screen session, the clearing of the screen is somehow disabled. I tried several things, like screen -T xterm or putting the autonuke statement in my ~/.screenrc. Also, inside the screen session export TERM=xterm tset has no effect. So, now I'm out of ideas. Any help appreciated.

• Drawing texture does not work anymore with a small amount of triangles

  - by Paul

  When i draw lines, the vertices are well connected. But when i draw the texture inside the triangles, it only works with i<4 in the for loop, otherwise with i<5 for example, there is a EXC_BAD_ACCESS message, at @synthesize textureImage = _textureImage. I don't understand why. (The generatePolygons method seems to work fine as i tried to draw lines with many vertices as in the second image below. And textureImage remains the same for i<4 or i<5 : it's a 512px square image). Here are the images : What i want to achieve is to put the red points and connect them to the y-axis (the green points) and color the area (the green triangles) : If i only draw lines, it works fine : Then with a texture color, it works for i<4 in the loop (the red points in my first image, plus the fifth one to connect the last y) : But then, if i set i<5, the debug tool says EXC_BAD_ACCESS at the synthesize of _textureImage. Here is my code : I set a texture color in HelloWordLayer.mm with : CCSprite *textureImage = [self spriteWithColor:color3 textureSize:512]; _terrain.textureImage = textureImage; Then in the class Terrain, i create the vertices and put the texture in the draw method : @implementation Terrain @synthesize textureImage = _textureImage; //EXC_BAD_ACCESS for i<5 - (void)generatePath2{ CGSize winSize = [CCDirector sharedDirector].winSize; float x = 40; float y = 0; for(int i = 0; i < kMaxKeyPoints+1; ++i) { _hillKeyPoints[i] = CGPointMake(x, y); x = 150 + (random() % (int) 30); y += 30; } } -(void)generatePolygons{ _nPolyVertices = 0; float x1 = 0; float y1 = 0; int keyPoints = 0; for (int i=0; i<4; i++){ /* HERE : 4 = OK / 5 = crash */ //V0: at (0,0) _polyVertices[_nPolyVertices] = CGPointMake(x1, y1); _polyTexCoords[_nPolyVertices++] = CGPointMake(x1, y1); //V1: to the first "point" _polyVertices[_nPolyVertices] = CGPointMake(_hillKeyPoints[keyPoints].x, _hillKeyPoints[keyPoints].y); _polyTexCoords[_nPolyVertices++] = CGPointMake(_hillKeyPoints[keyPoints].x, _hillKeyPoints[keyPoints].y); keyPoints++; //from point at index 0 to 1 //V2, same y as point n°2: _polyVertices[_nPolyVertices] = CGPointMake(0, _hillKeyPoints[keyPoints].y); _polyTexCoords[_nPolyVertices++] = CGPointMake(0, _hillKeyPoints[keyPoints].y); //V1 again _polyVertices[_nPolyVertices] = _polyVertices[_nPolyVertices-2]; _polyTexCoords[_nPolyVertices++] = _polyVertices[_nPolyVertices-2]; //V2 again _polyVertices[_nPolyVertices] = _polyVertices[_nPolyVertices-2]; _polyTexCoords[_nPolyVertices++] = _polyVertices[_nPolyVertices-2]; //V3 = same x,y as point at index 1 _polyVertices[_nPolyVertices] = CGPointMake(_hillKeyPoints[keyPoints].x, _hillKeyPoints[keyPoints].y); _polyTexCoords[_nPolyVertices] = CGPointMake(_hillKeyPoints[keyPoints].x, _hillKeyPoints[keyPoints].y); y1 = _polyVertices[_nPolyVertices].y; _nPolyVertices++; } } - (id)init { if ((self = [super init])) { [self generatePath2]; [self generatePolygons]; } return self; } - (void) draw { //glDisable(GL_TEXTURE_2D); glDisableClientState(GL_COLOR_ARRAY); glDisableClientState(GL_TEXTURE_COORD_ARRAY); glBindTexture(GL_TEXTURE_2D, _textureImage.texture.name); glColor4f(1, 1, 1, 1); glVertexPointer(2, GL_FLOAT, 0, _polyVertices); glTexCoordPointer(2, GL_FLOAT, 0, _polyTexCoords); glDrawArrays(GL_TRIANGLE_STRIP, 0, (GLsizei)_nPolyVertices); glColor4f(1, 1, 1, 1); for(int i = 1; i < 40; ++i) { ccDrawLine(_polyVertices[i-1], _polyVertices[i]); } // restore default GL states glEnable(GL_TEXTURE_2D); glEnableClientState(GL_COLOR_ARRAY); glEnableClientState(GL_TEXTURE_COORD_ARRAY); } Do you see anything wrong in this code? Thanks for your help

• Book Review: Professional ASP.Net MVC4

  - by Sam Abraham

  The past few weeks have been particularly busy as I continue to dedicate a bigger portion of my free time to refreshing my memory and enhancing my knowledge of best practices pertaining to technologies we plan on using for a major upcoming project. In this blog post, I will be providing a brief overview of my latest reading “Professional ASP.Net MVC4” by Jon Galloway, Phil Haack, Brad Wilson and K. Scott Allen. This book is a must read for web developers looking to enhance their MVC expertise with best practices and tips shared from recognized industry experts. This book takes the reader on a 16-chapter long journey towards being a better ASP.NET MVC developer with chapter 16 putting all information covered in practical context by dissecting the implementation of Nuget.org, a real-life open-source, ASP.NET MVC project.  All code samples referenced in this book are conveniently accessible via NuGet, a free, open-source Library package manager that installs as a Visual Studio Extension. Chapters 2, 3 and 4 thoroughly cover MVC’s various components: Controllers “C”, Views “V” and Models “M” respectively. Chapter 5 covers additional extension methods (Helpers) provided to speed and ease the use of common HTML elements such as forms, textboxes, grids, to name a few… Chapter 6 tackles built-in validation while providing examples and use cases on implementing custom validation that plugs into the MVC framework. Chapters 7 thru 13 discusses the latest on Membership, Ajax, Routing, NuGet and the ASP.Net Web API. Chapters 12 (Dependency Injection) and 13 (Unit Testing) demonstrate a big competitive advantage of MVC with its ease of test-ability and plug-ability. Chapters 14 and 15 targets the advanced developer showcasing how to extend MVC to customize and replace every piece in the framework.In conclusion, I strongly recommend Professional ASP.NET MVC 4 as an excellent read for both developers already using MVC as well as those getting started with the framework.   Many thanks to the Wiley/Wrox User Group Program for their support of our West Palm Beach Developers’ Group.  You can access my reviews of books I recently read: Professional ASP.NET Design Patterns Professional WCF 4.0 Inside Windows Communication Foundation Inside Microsoft SQL Server 2008 series

• How to use UMLFS?

  - by Vi

  I'm trying to mount what is inside UML session as FUSE filesystem on host. There's "uml_mount" program which looks like a thing for this purpose, but it fails. What is UMLFS (I haven't found any documentation at all) and how to mount it? uml_mount mounts FUSE filesystem and starts uml_mconsole <umid> umlfs <file descriptor> which tries to send this file descriptor to UML kernel (to deal with further FUSE things), but sending fails. Also I haven't found any signs of FUSE inside a kernel. Do I need some special patch for this?

• Snap App Windows to Pre-Defined Screen Sections with Acer GridVista

  - by Asian Angel

  The window snapping feature in Windows 7 and the ability to organize monitor(s) into specific gridded sections have both become popular lately. If you love the idea of having both combined in a single software then join us as we look at Acer GridVista. Note: Acer GridVista works with Windows XP, Vista, & 7. It will also work with dual monitors. Setup Acer GridVista comes in a zip file format and at first you might assume that it is portable in nature but it is not. Once you unzip the enclosed folder you will need to double click on “Setup.exe” to install the program. Acer GridVista in Action Once you have installed the program and started it up all that you will notice at first is the new “System Tray Icon”. Here you can see the “Context Menu”… The only menu command that you will likely use most of the time is the “Grid Configuration Command”. Notice that for our single monitor setup that it lists “Display 1”. The “Single Setting” is enabled by default and you can easily choose the layout that best suits your needs. The enabled layout style will always be highlighted in yellow for easy reference. For our example we chose the “Triple (primary at right)” layout style. Each section will be specifically numbered as shown here. Do not worry…the grid and numbers only appear for a moment and then become invisible again until you move an app window into that section/area of your screen. On every regular app window that you open you will notice three new buttons in the upper right corner. Here is what each of these new buttons do: Acer GridVista Extensions (Transparent, Send To Window Grid, About Acer GridVista): Viewable in a drop-down menu Lock To Grid (Enable/Disable): Enabled by default –> Note: Set to disable on a particular window to keep it free of the “grid locking function” Always On Top (Enable/Disable): Disabled by default A good look at the “Extensions Drop-Down Menu” where you can set an app window to be transparent or send it to a specific screen section on your monitor(s). If you open an app it will not automatically lock into a specific section. To lock the window into a specific section drag-and-drop the app window into the desired section. Notice the red outline and highlighted number on “Section 2” below. The red outline and highlighted number serves as an indicator that if you release the app window at that moment it will lock into the outlined/highlighted section. Now that Notepad is locked into “Section 2” you can see that it is maximized within that section. Continue to drag-and-drop your app windows into the appropriate sections as desired…apps can still be reduced to the “Taskbar” the same as before. Options These are the options available for Acer GridVista… Conclusion If you have been wanting the ability to “snap” windows and organize them into specific screen areas then Acer GridVista is definitely a program that you should try out.

• Merely chainloading an Acer Recovery Partition deleted all data

  - by WindowsEscapist

  I was starting a backup of Acer's factory restore partition located inside of an extended partition to determine whether or not it still worked. I clicked "take no action" once I saw that it had, in fact, successfully started up. However, when I rebooted, I got an "error: no such partition" and was dropped to a GRUB recovery prompt. Upon further investigation, I discovered that all partitions inside the extended partition were gone except for the recovery partition! What happened? How can I fix this? testdisk doesn't find the deleted partitions!

• How to avoid game objects accidentally deleting themselves in C++

  - by Tom Dalling

  Let's say my game has a monster that can kamikaze explode on the player. Let's pick a name for this monster at random: a Creeper. So, the Creeper class has a method that looks something like this: void Creeper::kamikaze() { EventSystem::postEvent(ENTITY_DEATH, this); Explosion* e = new Explosion; e->setLocation(this->location()); this->world->addEntity(e); } The events are not queued, they get dispatched immediately. This causes the Creeper object to get deleted somewhere inside the call to postEvent. Something like this: void World::handleEvent(int type, void* context) { if(type == ENTITY_DEATH){ Entity* ent = dynamic_cast<Entity*>(context); removeEntity(ent); delete ent; } } Because the Creeper object gets deleted while the kamikaze method is still running, it will crash when it tries to access this->location(). One solution is to queue the events into a buffer and dispatch them later. Is that the common solution in C++ games? It feels like a bit of a hack, but that might just be because of my experience with other languages with different memory management practices. In C++, is there a better general solution to this problem where an object accidentally deletes itself from inside one of its methods?

• Should you always pass the bare minimum data needed into a function

  - by Anders Holmström

  Let's say I have a function IsAdmin that checks whether a user is an admin. Let's also say that the admin checking is done by matching user id, name and password against some sort of rule (not important). In my head there are then two possible function signatures for this: public bool IsAdmin(User user); public bool IsAdmin(int id, string name, string password); I most often go for the second type of signature, thinking that: The function signature gives the reader a lot more info The logic contained inside the function doesn't have to know about the User class It usually results in slightly less code inside the function However I sometimes question this approach, and also realize that at some point it would become unwieldy. If for example a function would map between ten different object fields into a resulting bool I would obviously send in the entire object. But apart from a stark example like that I can't see a reason to pass in the actual object. I would appreciate any arguments for either style, as well as any general observations you might offer. I program in both object oriented and functional styles, so the question should be seen as regarding any and all idioms.

• An experiment: unlimited free trial

  - by Alex.Davies

  The .NET Demon team have just implemented an experiment that is quite a break from Red Gate's normal business model. Instead of the tool expiring after the trial period, it now continues to work, but with a new message that appears after the tool has saved you a certain amount of time. The rationale is that a user that stops using .NET Demon because the trial expired isn't doing anyone any good. We'd much rather people continue using it forever, as long as everyone that finds it useful and can afford it still pays for it. Hopefully the message appearing is annoying enough to achieve that, but not for people to uninstall it. It's true that many companies have tried it before with mixed results, but we have a secret weapon. The perfect nag message? The neat thing for .NET Demon is that we can easily measure exactly how much time .NET Demon has saved you, in terms of unnecessary project builds that Visual Studio would have done. When you press F5, the message shows you the time saved, and then makes you wait a shorter time before starting your application. Confronted with the truth about how amazing .NET Demon is, who can do anything but buy it? The real secret though, is that while you wait, .NET Demon gives you entertainment, in the form of a picture of a cute kitten. I've only had time to embed one kitten so far, but the eventual aim is for a random different kitten to appear each time. The psychological health benefits of a dose of kittens in the daily life of the developer are obvious. My only concern is that people will complain after paying for .NET Demon that the kittens are gone.

• A Fresh Start

  - by Laila

  As you may already be aware, I'm no longer responsible for the .NET Reflector newsletter. That publication is now in the very capable hands of the Reflector team. But fear not; starting in early April, I'll be launching a brand new .NET Newsletter, and I invite you to enjoy the very first edition by subscribing to our new mailing list, or by updating your Simple-Talk subscriptions, and joining the .NET Newsletter mailing list. With a fresh and snappy design (it might even be described as idiosyncratic. but I can say no more at this stage), we'll be making a brand new start. Each month, a member of my team (that's the Red Gate .NET team) will host the .NET Newsletter, bringing you the choicest cuts of breaking news, the very best .NET content from Simple-Talk, alongside details of hot upcoming events. To top it off, not only will you be among the first to get access to free resources (including free wall-charts, training videos and eBooks), but you'll also get exclusive access to betas, early access programs, and special offers. We can't wait to share the new design and exciting new content with you! If you have any questions about the changes to the newsletter, please feel free to send an email to [email protected] or post a comment on my blog. If I don't hear from you before next month, then I'll simply say that I hope you enjoy the new look. Cheers, Laila

• ASA firewalls: how does stateful filtering affect my access lists?

  - by Nate

  Ok, so assume that I have an ingress access list that looks like this: access-list outside_in extended ip permit any X.Y.Z.1 eq 25 access-group outside_in in interface outside And I want to do egress filtering. I want to allow inside machines to respond on port 80, and I want to allow ports over 1024. Given that the firewall is statefull, do I need to have the rule access-list inside_in extended ip permit X.Y.Z.1 any eq 25 in my inside_in ACL, or can I get away with just access-list inside_in extended ip permit any any gt 1024 access-group inside_in in interface inside In other words, if I apply an egress access list, do I have to explicitly allow machines to respond to requests allowed by the ingress access list, or does the statefullness of the firewall handle that for me? Thanks!

• In MMO game, how to handle user characters, who are offline?

  - by Deele

  In my medieval MMO game, players have their own character, that represents themselves inside game. Like a King. Players could have cities and armies, but King acts as main driving force. Then it comes to player, going offline/vacation/disconnect. How to deal with "offline King", to keep some sort of reality in game, without ruining everything for player. I have never liked unrealistic stuff in games, like appearing/dissapearing from thin air, like in WoW or other MMO RPG's, when it comes to connect/disconnect, like in Matrix movie, when you are disconnected, your "avatar" inside the system just vaninshes. Ok, if player char stays where it was left, other players who are online could kick his ass like offline player char was frozen? I see only one solution - give player char, while offline, some sort of AI, that controls char. Is there any other solutions? May be, some sort of legend/story, could make users only as inner-voice, leaving King just passively controlled by user, or other stuff... Please, help! I hope you understand my question.

• Looking for Full Screen Web-Browser in Vizio or Samsung TV's

  - by ScottCate

  I see that Google TV, inside Sony, has a Chrome browser. Is the same thing possible inside Vizio, or Samsung, or any other TV? The 42" Vizio is $499 at Costco, and the Sony with Google TV is $999. We're looking at a buch of these TV's that have build in Wi-Fi, to place around the office as Big Dashboards, and I don't want to have a computer attached to get web content on the screen. It's my understanding that both Samsung Apps, and Vizio Apps, use Yahoo Widgets as their ap engine. Anyone know of a way to get a full screen browser going, without attaching a computer? We thought of attaching an Apple TV, which can be jailbroken, but that is just another piece of equipment to lose, break, etc. Thank you!

• Searching for entity awareness in 3D space algorithm and data structure

  - by Khanser

  I'm trying to do some huge AI system just for the fun and I've come to this problem. How can I let the AI entities know about each other without getting the CPU to perform redundant and costly work? Every entity has a spatial awareness zone and it has to know what's inside when it has to decide what to do. First thoughts, for every entity test if the other entities are inside the first's reach. Ok, so it was the first try and yep, that is redundant and costly. We are working with real time AI over 10000+ entities so this is not a solution. Second try, calculate some grid over the awareness zone of every entity and test whether in this zones are entities (we are working with 3D entities with float x,y,z location coordinates) testing every point in the grid with the indexed-by-coordinate entities. Well, I don't like this because is also costly, but not as the first one. Third, create some multi linked lists over the x's and y's indexed positions of the entities so when we search for an interval between x,y and z,w positions (this interval defines the square over the spatial awareness zone) over the multi linked list, we won't have 'voids'. This has the problem of finding the nearest proximity value if there isn't one at the position where we start the search. I'm not convinced with any of the ideas so I'm searching for some enlightening. Do you people have any better ideas?

• Monitoring Baseline

  - by Grant Fritchey

  Knowing what's happening on your servers is important, that's monitoring. Knowing what happened on your server is establishing a baseline. You need to do both. I really enjoyed this blog post by Ted Krueger (blog|twitter). It's not enough to know what happened in the last hour or yesterday, you need to compare today to last week, especially if you released software this weekend. You need to compare today to 30 days ago in order to begin to establish future projections. How your data has changed over 30 days is a great indicator how it's going to change for the next 30. No, it's not perfect, but predicting the future is not exactly a science, just ask your local weatherman. Red Gate's SQL Monitor can show you the last week, the last 30 days, the last year, or all data you've collected (if you choose to keep a year's worth of data or more, please have PLENTY of storage standing by). You have a lot of choice and control here over how much data you store. Here's the configuration window showing how you can set this up: This is for version 2.3 of SQL Monitor, so if you're running an older version, you might want to update. The key point is, a baseline simply represents a moment in time in your server. The ability to compare now to then is what you're looking for in order to really have a useful baseline as Ted lays out so well in his post.

• Create FTP accounts with access to just some folders in the web directory

  - by Karevan

  I own a VPS server. At the moment I havent installed any FTP server on it, I am using SSH and SFTP only. I am using Debian 6 Squeeze and Apache2 service. The web directory is in /var/www/ Well, I wanted to create different FTP accounts and give access to some people to them (one account per user). In my web directory I have an structure like this: /var/www/mtaplugins/music/mplayer/music/ /var/www/mapuploader/ and more folders inside. I want to create an FTP account which should be able to just access one of those folders and the folders inside them. I would appreciate some recomendations or stept to follow before installing anything or doing anythong, because I dont have any idea about this. I was thinking in using ProFTPd but as I saw in the documentation it would just create an account for each user in my server, and I want to not create more users (I always use root) Thanks in advance

• Get Fanatical About Your Followers

  - by Mike Stiles

  In the fourth of our series of discussions with Aberdeen’s Trip Kucera, we touch on what fans of your brand have come to expect in exchange for their fandom. Spotlight: Around the Oracle Social office, we live for football. So when we think of a true “fan” of a brand, something on the level of a football fan is what comes to mind. But are brands trying to invest fans on that same level? Trip: Yeah, if you’re a football fan, this is definitely your time of year. And if you’ve been to any NFL games recently, especially if you hadn’t been for a few years previously, you may have noticed that from the cup holders to in-stadium Wi-Fi, there’s an increasing emphasis being placed on “fan-focused” accommodations. That’s what they’re known as in the stadium business. Spotlight: How are brands doing in that fan-focused arena? Trip: Remember fan is short for “fanatical.” Brands can definitely learn from the way teams have become fanatical about their fans, or in the social media world, their followers. Many companies consider a segment of their addressable social audience as true fans; I’ve even heard the term “super-fans” used. So just as fans know and can tell you nearly everything about their favorite team, our research shows that there’s a lot value from getting to know your social audience—your followers—at a deeper level. Spotlight: So did your research show there’s a lot to be gained by making fandom a two-way street? Trip: Aberdeen’s new social relationship management research suggests that companies should develop capabilities to better analyze their social audience at a more granular level. Countless “ripped from the headlines” examples, from “United Breaks Guitars” to the most recent British Airways social fiasco we talked about a few weeks ago show how social can magnify the impact of a single customer voice. Spotlight: So how do the companies who are executing social most successfully do that? Trip: Leaders, which are the top-performing companies in Aberdeen’s study, are showing the value of identifying and categorizing your social audience. You should certainly treat every customer as if they have 10,000 followers, because they just might, but you can also proactively engage with high-value customer and high-value influencers. Getting back to the football analogy, it’s like how teams strive to give every guest a great experience, but they really roll out the red carpet for those season ticket and luxury box holders. Spotlight: I’m not allowed in luxury boxes, so you’ll have to tell me what that’s like. But what is the brand equivalent of rolling out the red carpet? Trip: Leaders are nearly three times more likely than Followers to have a process in place that identifies key social influencers for engagement, and more than twice as likely to identify customer advocates for social outreach. This is the kind of knowledge that gives companies the ability to better target social messaging and promotions like we talked about in our last discussion, as well as a basis for understanding how to measure the impact of their social media programs. I’ll give you an example. I hosted an event at one of my favorite restaurants recently. I had mentioned them in a Tweet several weeks before the event, and on the day of the event, they Tweeted out that they were looking forward to seeing me that evening for the event. It’s a small thing, but it had a big impact and I’d certainly go back as a result. Spotlight: So what specifically can brands use and look at to determine where their potential super-fans are? Trip: Social graph analysis, which looks at both the demographic/psychographic trends as well as the behavioral connections, can surface important brand value. Aberdeen’s PR and Brand Management research indicated that top-performing companies are more than three times more likely than Followers to both determine demographic trends through social listening (44% vs. 13%), and to identify meaningful customer segments through social (44% vs. 12%). This kind of brand-level insight can complement and enrich traditional market research. But perhaps even more importantly, it can serve as an early warning system for customer experience failures. @mikestilesPhoto: freedigitalphotos.net

• This is probably a horrible idea; putting a Mac Mini in a mini-fridge [closed]

  - by Christian A. Strømmen

  Possible Duplicate: Putting servers inside a refrigerator? Just moved to a new house and had to place my Mac Mini server in the attic. Now this is really nice and cool at this time of the year, but during summer it's going to get blistering hot up there, meaning I have to find a solution that won't kill my Mac Mini and the two WD external drives I have connected to it. Is there any good reason why I couldn't just buy a mini-fridge and put them inside that? The only thing I can think of is condensation building up, but I have no idea if that will be an issue or not. Something like this. And yes, I'm pretty sure this is a terrible idea, but I figured it was worth mentioning here and getting some feedback. What other options are there?

• Apache does not serve non-locally

  - by yodaj007

  I have a freshly installed instance of Fedora Core 16 inside VirtualBox using bridged networking. On it, as root I typed in: yum -y install httpd service httpd start ifconfig Inside the VM, I can open a web browser to 'localhost' and I get the Apache test page. It works. But in Windows (the machine hosting the VM), I point my browser to the IP address returned by ifconfig (192.168.2.122). The connection times out. I can go to a command prompt and ping the VM. Is there a firewall or something that comes with Fedora by default? Or is there something I need to change in a config file?

• Strategy for hosting 700+ domains names, each with a static HTML site

  - by jonschlinkert

  I have a portfolio of more than 700 domain names, and ideally I'd like to put up a single-page HTML/CSS/JavaScript webpage for each domain. Is there a system/strategy/workflow that will allow me to: Automate the deployment of new websites, quickly and easily without having to manually initiate each new website in an admin panel. For instance, I've seen dropbox-based solutions that claim to make it simple to setup new websites on your dropbox account, but you still have to set each one up in an admin interface first. It would be so much easier to have a folder naming convention that allowed the user to easily clone/copy/duplicate sites inside their Dropbox App folder (https://www.dropbox.com/developers/blog/23) to create new ones. Sounds interesting, however... It's easy to manage CNAMEs on the registrar-side, but is there a way to quickly associate CNAMEs with new websites (on the hosting side), maybe using the method offered by gh-pages-style (https://help.github.com/articles/setting-up-a-custom-domain-with-pages)? With GitHub's gh-pages, all you have to do is drop a file called CNAME into your repo, with the domain name you want associated with the repo inside the file. gh-pages isn't a good solution for what I'm doing though unfortunately. I'm also a front-end developer, specializing in rapid web development and "front-end build systems", so I building and maintaining static assets for hundreds of sites is no problem. It's the hosting-side that I really struggle with. Any suggestions?
