• Citrix Xen VM's lose networking

  - by Ash

  My client has a XenServer 6.0.2 installation with 2 Window Server 2008 R2 virtual machines. Whenever the virtual machines are rebooted they lose their IP settings (IP address, subnet, gateway). Each time after a reboot I need to login to each VM via XenCenter and re-apply the required static IP settings. This causes issues with connected iSCSI drives within each VM - drives need to be reconnected after each reboot. For example, a network adapter has the following settings pre-reboot: Description . . . . . . . . . . . : Citrix PV Ethernet Adapter #0 Physical Address. . . . . . . . . : C6-FB-A2-4F-2C-F3 IPv4 Address. . . . . . . . . . . : 10.101.0.101(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 10.101.0.10 DNS Servers . . . . . . . . . . . : 10.101.0.100 NetBIOS over Tcpip. . . . . . . . : Enabled Post-reboot: Description . . . . . . . . . . . : Citrix PV Ethernet Adapter #0 Physical Address. . . . . . . . . : C6-FB-A2-4F-2C-F3 Autoconfiguration IPv4 Address. . : 169.254.153.174(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.0.0 Default Gateway . . . . . . . . . : DNS Servers . . . . . . . . . . . : 10.101.0.100 NetBIOS over Tcpip. . . . . . . . : Enabled Under XenCenter -- Virtual Network Interfaces, each adapter is set to a static MAC address (i.e. "Use this MAC address"). I have tried the following commands within one VM but this had no effect: netsh winsock reset catalog netsh int ip reset Can someone please help?

• When a co-worker asks you to teach him what you know, do you share the information or keep it to yourself? [closed]

  - by Chuck

  I am the only developer/DBA in a small IT department. There is another guy who can do it, but he's more of a backup as he spends his time working on IT support stuff. Anyway we have a new hire and I've been training him on the IT support side of things. Seems like he is eager to learn and be productive, but nobody is going out of their way to show him anything. He's been asking me to teach him database design, SQL, etc. For some reason, the boss has him working with me. He is also sending him to meetings that I go to, yet he hasn't said outright that I have to teach him anything. Meanwhile, the boss insists on doing a lot of the support work himself (i.e. he hoards information and doesn't delegate to anyone). I'm a little bit on the fence. First, the new guy doesn't yet have a strong foundation on the IT support functions which is where we really need help at this time. Second, I paid thousands of dollars for classes and spent many hours learning this stuff. Is it my responsibility to teach others skills that I had to learn on my own? Others here really aren't quick to share information so I'm not sure that I should either in this environment. I do know that if I get him involved, and get him started on projects, then I'd be responsible for his mistakes. I had to take the heat for the other guy when he made mistakes. OTOH the guy wants to learn something, is motivated, and I don't want to stop him. We've had our share of slackers in the group and it's nice to have someone who is willing to work for a change. So what would you guys do? Would you teach him the skills that you spent all of that time learning? Set him up with a test database on his PC and recommend some books for him? Encourage him to get a strong foundation in IT support first and ask later? We haven't had a new hire in years, let alone one that is interested in what I do, so this is new to me.

• Is it smart to take a year off from school to get experience?

  - by user134147

  firstly I apologize if this question is not appropriate for the site, but I've seen other similar (though slightly deviant) questions on this sight before and I know the people here are the most qualified to answer my question. Anyways, I'm currently between my sophomore and junior years at a 4 year university, and after a bit of deliberation I've decided on computer science as a major (BA, by the way, as a BS would require me to stay at least an extra year the way our program is set up). I've been interested now in programming for a few months and I've developed a passion for it in a very short time. I began learning C++, migrating to Java recently when I learned my school focuses on this language. Now, I should mention that the concept of higher education has never sat well with me, so part of my motivation for wanting to take time off is to truly challenge myself and see what I can accomplish when I actually try at something. The autodidact in me finds it difficult to focus on my passions while trying to keep a high GPA in unrelated classes. However, I understand the times we live in and therefore would plan to complete my degree after this year. So my question is whether or not the skills I learn in a year off from college could justify the time off from school. Unfortunately, I don't believe I know enough yet to gain any professional experience (internship, etc.) so I would mostly focus my time on learning Java and another language, possibly Wordpress (to gain an understanding of web programming concepts as I have not yet decided what field I want to get into, and to make some money to fund my off-year), and to delve into security concepts, which also interest me. I'm hoping I could work on projects, such as simple applications or contributions to open source software during this time to enhance my resume once I do finish school, so I can find a job out of college easier. I do not want to be the new hire who knows nothing beyond the concepts of his Java textbooks. Does anyone have any input about these thoughts of mine, or any ideas for where I should focus my studies or how high I might set the bar for my work? Thanks a lot everyone!

• Do functional generics exist or what is the correct name for them if they do?

  - by voroninp

  Consider the following generic class public class EntityChangeInfo<EntityType,TEntityKey> { ChangeTypeEnum ChangeType {get;} TEntityKeyType EntityKey {get;} } Here EntityType unambiguously defines TEntityKeyType. So it would be nice to have some kind of types' map public class EntityChangeInfo<EntityType,TEntityKey> with map < [ EntityType : Person -> TEntityKeyType : int] [ EntityType : Car -> TEntityKeyType : CarIdType ]> { ChangeTypeEnum ChangeType {get;} TEntityKeyType EntityKey {get;} } Another one example is: public class Foo<TIn> with map < [TIn : Person -> TOut1 : string, TOut2 : int, ..., TOutN : double ] [TIn : Car -> TOut1 : int, TOut2 :int, ..., TOutN : Price ] > { TOut1 Prop1 {get;set;} TOut2 Prop2 {get;set;} ... TOutN PropN {get;set;} } The reasonable question how this can be interpreted by the compiler? Well, for me it is just the sortcut for two structurally similar classes: public sealed class Foo<Person> { string Prop1 {get;set;} int Prop2 {get;set;} ... double PropN {get;set;} } public sealed class Foo<Car> { int Prop1 {get;set;} int Prop2 {get;set;} ... Price PropN {get;set;} } But besides this we could imaging some update of the Foo<: public class Foo<TIn> with map < [TIn : Person -> TOut1 : string, TOut2 : int, ..., TOutN : double ] [TIn : Car -> TOut1 : int, TOut2 :int, ..., TOutN : Price ] > { TOut1 Prop1 {get;set;} TOut2 Prop2 {get;set;} ... TOutN PropN {get;set;} public override string ToString() { return string.Format("prop1={0}, prop2={1},...propN={N-1}, Prop1, Prop2,...,PropN); } } This all can seem quite superficial but the idea came when I was designing the messages for our system. The very first class. Many messages with the same structrue should be discriminated by the EntityType. So the question is whether such construct exist in any programming language?

• JavaFX: Use a Screen with your Scene!

  - by user12610255

  Here's a handy tip for sizing your application. You can use the javafx.stage.Screen class to obtain the width and height of the user's screen, and then use those same dimensions when sizing your scene. The following code modifies default "Hello World" application that appears when you create a new JavaFX project in NetBeans. package screendemo; import javafx.application.Application; import javafx.event.ActionEvent; import javafx.event.EventHandler; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.stage.Stage; import javafx.stage.Screen; import javafx.geometry.Rectangle2D; public class ScreenDemo extends Application { public static void main(String[] args) { Application.launch(args); } @Override public void start(Stage primaryStage) { primaryStage.setTitle("Hello World"); Group root = new Group(); Rectangle2D screenBounds = Screen.getPrimary().getVisualBounds(); Scene scene = new Scene(root, screenBounds.getWidth(), screenBounds.getHeight()); Button btn = new Button(); btn.setLayoutX(100); btn.setLayoutY(80); btn.setText("Hello World"); btn.setOnAction(new EventHandler() { public void handle(ActionEvent event) { System.out.println("Hello World"); } }); root.getChildren().add(btn); primaryStage.setScene(scene); primaryStage.show(); } } Running this program will set the Stage boundaries to visible bounds of the main screen. -- Scott Hommel

• Hosing website on own server. What is Hardware requirement and Cost [closed]

  - by KuKu

  As i am about to finish my dream website, i need to host it on some server. I checked Amazon AWS Free Tier, i found it pretty complex. As i made full website in java(JSP + Servlet + mysql + Node.js), its been expensive to host. So i thought that why not to host on own server so that i will be fully dependent on my resources, not on any one else. And i know, in future i need to pay more and more to the other hosting company(because of uploading images and number of incoming users). So my question is, On initial stage what kind of hardware i will required. What can be the cost of that hardware? I already have 12MBPS broadband connection, will it be sufficient? It has static IP Address as well.

• Keep ASP.NET site and content separate

  - by Nelson

  I have an ASP.NET site in folder x. Currently lots of other static content gets added to folder x and gets mixed in, making it one big mess. I would like to keep the ASP.NET site and the content separate somehow. I know you can create virtual directories in IIS, but there are LOTS and even some content in the root. The content people are not technical and really need an easy way to add it. I would stick everything in a subfolder (they don't touch anything outside, I don't touch their folder), but that would change their URLs (www.example.com/something to www.example.com/content/something). I almost need a way to "merge" two folders and have them act as one. I'm guessing that is impossible since there could be file conflicts, etc. Any other ways I can achieve this?

• Cannot Ping PS3 Using a Wired Connection

  - by Post

  PS3 is using the inbuilt wireless network adapter (I cannot change this) When I try to ping the PS3 from ANY computer which is on a wired ethernet connection, I get Request Timed Out errors. Whenever I ping from a computer with a wireless connection, it works just fine. To be clear: Pinging from Wireless PC to Wireless PS3 works Pinging from Wired PC to Wireless PS3 fails I have tried this on several PC's and Laptops all with the same results. As an attempted solution I have set up static IP's on all related devices. More information: Default Gateway = 192.168.2.1 PS3(wireless) = 192.168.2.100 PC(wired) = 192.168.2.99 Subnet Mask(for both devices, I have made sure) = 255.255.255.0 Thanks

• How do I get my 192.168.* Linux server accessible via http://hostname/?

  - by rfrankel

  (Sorry if this question isn't worded well and/or is duplicate. I'm not a networking guy and I'm probably not using the right terms...this also makes it hard to see if this has already been answered.) I'm running a CentOS server in VirtualBox, Windows host, and I can see access Apache-hosted pages at http://192.168.1.109/ from machines on my LAN. But what I'd like is for people to be able to type http://hostname/ ...both because it's easier and primarily because I'm not sure that local IP is static. I'm not really sure how to proceed - could someone point me in the right direction? Thanks.

• Nginx and low-speed connections: request terminates after 253 seconds

  - by meze

  I'm trying to make nginx to handle static files. All is working fine except that when I throttle my connection speed to 8kbit/s, the loading process of a file just stops after 253-255 seconds (4.2 min according to chrome). No error in the log, the status code is 200 but the response is received partially. If I disable nginx and make apache to send the same file - it loads successfully after 10 minutes. The config I use for debugging is: client_header_buffer_size 16k; large_client_header_buffers 4 8k; client_max_body_size 50m; client_body_buffer_size 16k; client_header_timeout 20m; client_body_timeout 20m; send_timeout 20m; Did i miss some configurations?

• Should we persist with an employee still writing bad code after many years?

  - by user94986

  I've been assigned the task of managing developers for a well-established company. They have a single developer who specialises in all their C++ coding (since forever), but the quality of the work is abysmal. Code reviews and testing have revealed many problems, one of the worst being memory leaks. The developer has never tested his code for leaks, and I discovered that the applications could leak many MBs with only a minute of use. User's were reporting huge slowdowns, and his take was, "it's nothing to do with me - if they quit and restart, it's all good again." I've given him tools to detect and trace the leaks, and sat down with him for many hours to demonstrate how the tools are used, where the problems occur, and what to do to fix them. We're 6 months down the track, and I assigned him to write a new module. I reviewed it before it was integrated into our larger code base, and was dismayed to discover the same bad coding as before. The part that I find incomprehensible is that some of the coding is worse than amateurish. For example, he wanted a class (Foo) that could populate an object of another class (Bar). He decided that Foo would hold a reference to Bar, e.g.: class Foo { public: Foo(Bar& bar) : m_bar(bar) {} private: Bar& m_bar; }; But (for other reasons) he also needed a default constructor for Foo and, rather than question his initial design, he wrote this gem: Foo::Foo() : m_bar(*(new Bar)) {} So every time the default constructor is called, a Bar is leaked. To make matters worse, Foo allocates memory from the heap for 2 other objects, but he didn't write a destructor or copy constructor. So every allocation of Foo actually leaks 3 different objects, and you can imagine what happened when a Foo was copied. And - it only gets better - he repeated the same pattern on three other classes, so it isn't a one-off slip. The whole concept is wrong on so many levels. I would feel more understanding if this came from a total novice. But this guy has been doing this for many years and has had very focussed training and advice over the past few months. I realise he has been working without mentoring or peer reviews most of that time, but I'm beginning to feel he can't change. So my question is, would you persist with someone who is writing such obviously bad code?

• Determining whether two fast moving objects should be submitted for a collision check

  - by dreta

  I have a basic 2D physics engine running. It's pretty much a particle engine, just uses basic shapes like AABBs and circles, so no rotation is possible. I have CCD implemented that can give accurate TOI for two fast moving objects and everything is working smoothly. My issue now is that i can't figure out how to determine whether two fast moving objects should even be checked against each other in the first place. I'm using a quad tree for spacial partitioning and for each fast moving object, i check it against objects in each cell that it passes. This works fine for determining collision with static geometry, but it means that any other fast moving object that could collide with it, but isn't in any of the cells that are checked, is never considered. The only solution to this i can think of is to either have the cells large enough and cross fingers that this is enough, or to implement some sort of a brute force algorithm. Is there a proper way of dealing with this, maybe somebody solved this issue in an efficient manner. Or maybe there's a better way of partitioning space that accounts for this?

• Turn on PC power remotely through the Internet?

  - by W.N.

  I use SVN for my work at home and office, but I usually forget to commit the changes before shutdown. Therefore, I wish I could turn on my home/office PC at office/home. I already have TeamViewer installed on both PCs, so it will be okay as soon as the power is turned on. I have read many articles about this, I found both my PC and office computers support Wake-on-LAN. However, I don't know much about other config. And I need to turn on my computers through the Internet, not on LAN. My office Internet connection has static IP, however, my home Internet connection has dynamic IP, it changes as soon as I reset the modem, but it is not a big problem, I rarely turn the Internet modem off. And I don't have privilege to config office Internet connection, but I have Administration privilege on both PCs. Please give me details steps to turn on my office PC from home, and turn on my home PC from office.

• How to secure a VM while allowing customer RDS (or equivalent) access to its desktop

  - by ChrisA

  We have a Windows Client/(SQL-)Server application which is normally installed at the customer's premises. We now need to provide a hosted solution, and browser-based isn't feasible in the short term. We're considering hosting the database ourselves, and also hosting the client in a VM. We can set all this up easily enough, so we need to: ensure that the customer can connect easily, and also ensure that we suitably restrict access to the VM (and its host, of course) We already access the host and guest machines across the internet via RDS, but we restrict access to it to only our own internal, very small, set of static IPs, and of course theres the 2 (or 3?)-user limit on RDS connections to a remote server. So I'd greatly appreciate ideas on how to manage: the security the multi-user aspect. We're hoping to be able to do this initially without a large investment in virtualisation infrastructure - it would be one customer only to start with, with perhaps two remote users. Thanks!

• Need to configure multiple default gateways for four seperate physical network ports for a FreeBSD Webserver

  - by user20010

  I need to configure default gateways for four separate physical network interfaces for a FreeBSD Webserver. Basically, this is a web server that needs to be accessed by multiple WANS. I've been using various online resources, and a combination of setfib, pf, and ipfw. This web server will be deployed in multiple sites where access to next hop router info is not available, so we can't use static routes. We've used setfib to successfully create multiple routing tables and can ping beyond every default gateway we've created. Using setfib # ping ip.addr.what.ever we can ping anything available on a wan and beyond the router. The problem is we can't get Apache web server (port 80) traffic to route out when external users access the server(box). Multiple people have examples of binding setfib to ipfw commands, but none of them seem to work.

• 2x ATI FireMV 2250 not working

  - by Brett Rigby

  I've just bought 2x ATI FireMV 2250 cards from a reputable seller on ebay... one is a PCI-E x1 and the other is a PCI-E x16. Problem is, neither works in my Dell Vostro 220 PC... Both cards appear to not work. Is there something I'm missing? The seller used an anti-static bag for one of the cards, syaing that: "You Must connect this graphics board to the computer's power supply" but there's no socket for that, nor any indication. I have contacted the seller, but thought I'd raise it here, as it seems strange that two cards can be non-functioning.

• Why do arrays in java choose the biggest? [closed]

  - by Trycon

  I'm new to java so I was reading my book with these code: public class mainb1 { public static void main (String[] args) { //datatype name = expression; //food int min, max; int num[] = new int[10]; num[0]=99; num[1]=90; num[2]=-100; num[3]=100; num[4]=23; num[5]=50; num[6]=123; num[7]=3123; num[8]=2; num[9]=923; min=max=num[1]; for(int x=0;x<10;x++) { if(num[x]<min)min=num[x]; if(num[x]>max)max=num[x]; } System.out.println("Min: "+min+" max: "+max); } } It chose the biggest and the smallest. I don't get it if max was 99, then the last one that is lesser than min is 2? How did this array choose to pick the smallest and the biggest? Can someone explain?

• Cisco WLAN Controller not pushing out DHCP addresses, what else could it be?

  - by Name

  On our Cisco WLAN Controller web interfaces, in Controller Interfaces, I have made a new interface with these settings: VLAN Identifier 202 IP Address 172.16.202.1 Netmask 255.255.255.0 Gateway 172.16.202.254 Primary DHCP Server 172.16.100.3 Secondary DHCP Server 172.16.100.2 Port: LAG I've also made a new WLAN and assigned it to the above interface. I have saved changes. But our wireless devices, although they seem to authenticate with the WLAN fine, they always get stuck on "obtaining DHCP address", so it seems the WLAN Controller isn't pushing out DHCP addresses to our devices. We do have a DHCP scope for the above in Windows Server 2008 R2 and everything there seems fine. If I connect a device with a static address (e.g. 172.16.202.10), it will connect. Stuck on what to do :(

• Site's performance slows over time until Apache is restarted

  - by udbhav

  I'm running a Django app w/ Nginx and Apache. All our static media is stored on S3, and basically it takes a while for the app to check if thumbnails have been created every time a page is loaded. To alleviate this problem, I'm caching the output of the templates w/ memcached. Over the course of an hour or two, the site's speed goes down significantly, until I restart apache, and then all is good for a little while. I have very little sysadmin experience, and was hoping somebody could at least point me in the right direction.

  We are experiencing an interesting issue with IIS 7.5 static caching and a css file. When we use IE to hit the page in question everything works fine - 200 OK on css file. When we refresh the page it works fine - 304 Not Modified on css file. When I refresh again with control key it reloads fine - 200 OK on css file. Now if I do a control key + refresh multiple times in a row really fast the css fails to load and in the developer tools network it says "Loading..." for the css file and it hangs never coming back. Any ideas?

• How does the performance of pure Nginx compare to cpNginx?

  - by jb510

  There is now a Cpanel plugin to fairly easily setup Nginx as a reverse proxy on a Cpanel/Apache server. I've been simultaneously interested in setting up my first unmanaged VPS and my first Nginx server and as a masochist figured why not combine the two. I'm wondering however if it's worth setting up a pure Nginx server vs trying out cpNginx on Apache? My goal is solely to host WordPress sites and while what I've read raves about Nginx's is exceptional ability serving static at least as a reverse proxy, I am unclear if there is substantial benefit to running a pure nginx with eAccelorator over cpNginx on Apache for dynamic sites? Regardless I'll be running W3TC on all sites to cache content, but am still interested if there are big CPU reductions running PHP scripts under pure Nginx over cpNginx?

• Windows 2003 Server Suddenly Drops Connections to everything but PING and port 80 (webserver)

  - by Urda

  Hi, I'm running a Windows 2003 Dedicated server, and the box has been rock solid for more than 2 years now. Just recently, I have had an issue where after a certain ammount of time the server will just stop accepting connections on all ports except 80, and still responds to pings. If you surf to a static HTML page on the box, you can display it. If you pull up a PHP file that has an outside database connection, it fails. RDP refuses to connect, and LogMeIn reports that "The connection was reset" The only fix at this time is to have the provider physically reboot my box to correct the issue. The event log doesn't seem to be leaving helpful messages, and I am at a lost to what is causing this error since I have not installed any new software in months on it. Any tips or help would be appreciated to tracking down this issue. I don't mind updating the question as responses come in, I just do not know where to start troubleshooting because it seems random at this time.

• Rectangular Raycasting?

  - by igrad

  If you've ever played The Swapper, you'll have a good idea of what I'm asking about. I need to check for, and isolate, areas of a rectangle that may intersect with either a circle or another rectangle. These selected areas will receive special properties, and the areas will be non-static, since the intersecting shapes themselves will also be dynamic. My first thought was to use raycasting detection, though I've only seen that in use with circles, or even ellipses. I'm curious if there's a method of using raycasting with a more rectangular approach, or if there's a totally different method already in use to accomplish this task. I would like something more exact than checking in large chunks, and since I'm using SDL2 with a logical renderer size of 1920x1080, checking if each pixel is intersecting is out of the question, as it would slow things down past a playable speed. I already have a multi-shape collision function-template in place, and I could use that, though it only checks if sides or corners are intersecting; it does not compute the overlapping area, or even find the circle's secant line, though I can't imagine it would be overly complex to implement. TL;DR: I need to find and isolate areas of a rectangle that may intersect with a circle or another rectangle without checking every single pixel on-screen.
