  • Sharing git repo without SSH

    - by user13323
    Hi. I'm trying to set-up a private git repo for code sharing, but found out that most of the implementations out there require use of SSH public keys, for example: http://www.jedi.be/blog/2009/05/06/8-ways-to-share-your-git-repository/ The only approach looking reasonable is the git-daemon, but it does not contain any authentication, and while it might be a good option for LAN, it is no go for remote working. Coming from SVN daemon, where all the access was conveniently controlled via single file, the SSH keys scheme quite a hurdle for me. Is there any way to securely share multiple Git repositories, without using SSH authentication? Thanks in advance!

  • create a bootable usb to automatic repair windows xp system32 files

    - by Edo Post
    Is it possible to create a script/live distro that replaces some system32 files? To explain it a bit more in details: There is a company that has multiple computers (think in 100/1000's) and they all are missing the same system32 files since the company's software removed it. The systems are distributed all over the world and are managed by "normal" people who don't have any knowledge about computers. I want to create a usb stick that i can mail to all those people which contains a script that executes when you boot the usb. this script should replace the missing system32 files without any user input is this possible, and if so how could i manage this?

  • Player & Level class structure in 2D python console game?

    - by Markus Meskanen
    I'm trying to create a 2D console game, where I have a player who can freely move around in a level (~map, but map is a reserved keyword) and interfere with other objects. Levels construct out of multiple Blocks, such as player(s), rocks, etc. Here's the Block class: class Block(object): def __init__(self, x=0, y=0, char=' ', solid=False): self.x = x self.y = y self.char = char self.solid = solid As you see, each block has a position (x, y) and a character to represent the block when it's printed. Each block also has a solid attribute, defining whether it can overlap with other solids or not. (Two solid blocks cannot overlap) I've now created few subclasses from Block (Rock might be useless for now) class Rock(Block): def __init__(self, x=0, y=0): super(Rock, self).__init__(x, y, 'x', True) class Player(Block): def __init__(self, x=0, y=0): super(Player, self).__init__(x, y, 'i', True) def move_left(self, x=1): ... # How do I make sure Player wont overlap with rocks? self.x -= x And here's the Level class: class Level(object): def __init__(self, name='', blocks=None): self.name = name self.blocks = blocks or [] Only way I can think of is to store a Player instance into Level's attributes (self.player=Player(), or so) and then give Level a method: def player_move_left(self): for block in self.blocks: if block.x == self.player.x - 1 and block.solid: return False But this doesn't really make any sense, why have a Player class if it can't even be moved without Level? Imo. player should be moved by a method inside Player. Am I wrong at something here, if not, how could I implement such behavior?

  • How can I avoid heroku stopping my dyno?

    - by iwein
    I build MVP's for clients regularly. Often I deploy on Heroku so they can see if the product works and demo it to prospects and investors. Then I have an application deployed on heroku, and it works like a charm, if not for one little thing. The app takes about 30 seconds to start up and heroku has the annoying habit of killing dyno's if they don't get traffic. My client is using the application for demo purposes now, so the load is extremely low and intermittent. I'm looking for a solution that is preferably: cost effective can be applied to multiple apps simultaneously What is the best way to avoid having the first request taking 30 seconds?

  • Question regarding Readability vs Processing Time

    - by Jordy
    I am creating a flowchart for a program with multiple sequential steps. Every step should be performed if the previous step is succesful. I use a c-based programming language so the lay-out would be something like this: METHOD 1: if(step_one_succeeded()) { if(step_two_succeeded()) { if(step_three_succeeded()) { //etc. etc. } } } If my program would have 15+ steps, the resulting code would be terribly unfriendly to read. So I changed my design and implemented a global errorcode that I keep passing by reference, make everything more readable. The resulting code would be something like this: METHOD 2: int _no_error = 0; step_one(_no_error); if(_no_error == 0) step_two(_no_error); if(_no_error == 0) step_three(_no_error); if(_no_error == 0) step_two(_no_error); The cyclomatic complexibility stays the same. Now let's say there are N number of steps. And let's assume that checking a condition is 1 clock long and performing a step doesn't take up time. The processing speed of Method1 can be anywhere between 1 and N. The processing speed of Method2 however is always equal to N-1. So Method1 will be faster most of the time. Which brings me to my question, is it bad practice to sacrifice time in order to make the code more readable? And why (not)?

  • System in low graphics, deleted linux, grub rescue, can't access windows

    - by First timer
    So I'm pretty new to Ubuntu but I managed to install it with no big problems on both my desktop and netbook. When I installed it on my brother's netbook everything went horribly wrong and now I fear the system is close to beyond repair. The problem was first that it said it did not have any space left (seemed ridiculous since it had a lot). Then Ubuntu began booting into a "System is running in low graphics mode error" which I then tried to fix, using all the tips I could find in here but nothing helped. I think the graphics error and lack of space might have been related but I can't be sure. Finally I gave up repairing Ubuntu and went for a reinstall. Shouldn't have done that! I read that I should simply open Ubuntu through a live usb and choose GParted to delete the Linux partitions so I did and rebooted accordingly. Next, I was to install Ubuntu but now I am only given the option to wipe the whole disk for Ubuntu, not install along with windows 7. If I access GParted I can still see the ntfs partitions that hold windows 7 (there are 2: one labeled RECOVERY and another labeled OS and boot) so why can't I access them? Btw. the OS and boot has a little red mark with a warning that 1 cluster is referenced to multiple times, don't know what that means. If I boot without the live usb I am sent directly into a grub rescue "black screen of the computer will follow no orders". Please, I know that the easiest might be to simply wipe the whole thing clean but there are important files and programs on windows 7. Is there a way to just access windows? It is a dell inspiron 1018 mini netbook, so I have no cd input and no windows 7 installation cd.

  • Best multi-platform mobile development tool, or use iPhone tools?

    - by Jesse Millikan
    I may be building a mobile app for a client soon. Their primary focus is the iPhone, but my boss would like to be able to target multiple platforms if it's feasible. The app will probably be a large but technically simple business application backed by a web service. So, here's the question as I see it: What is currently the strongest cross-platform mobile development tool that supports iOS? Would you choose it over native development tools? If you choose native, contrast it with a cross-platform tool you've used. In addition, For a project of the type we're expecting, what's the level of effort for your chosen tool versus other tools? What's the actual level of support of the tool for other platforms and their unique look and feel, capabilities, etc.? How thorough is the documentation of the product? How well do you like the development experience itself, e.g. the language, tools, documentation? Is it something you would choose to do long-term? I'll put a bounty out unless I get fantastic answers.

  • Move some iTunes library items to different drive?

    - by Sören Kuklau
    My internal hard drive is somewhat small, and I only regularly listen to a fraction of my iTunes library anyway, so I'd like to keep large portions on it on an external drive for archival purposes. Since dealing with multiple iTunes libraries is somewhat painful, the solution I'm looking for is to move individual items of the library to a different location, without compromising the "Keep organized" and "Copy files" settings. I found an AppleScript that I assume is supposed to do this, Move Files To Folder…, but it instead copies them, and doesn't update the library accordingly. I can do this manually by moving the file, then accessing it in iTunes — it'll prompt me for the new location. I just don't intend to do this one by one for thousands of files.

  • Would NetBSD be a good choice for a web server?

    - by Alexander
    I've the choice of crafting a NetBSD image for a Xen VPS host, and was just wanting to play around as I like BSD and wished to use it for my general web hosting. I will be hosting a low-mid traffic website and maybe a few other simple services. Do you think NetBSD would be a sufficient choice, in terms of general performance of multiple system users and fair amount of traffic to Apache compared to what Linux could normally handle? I am concerned if I do start to really like it and keep it, I may be limiting myself if I am to move further with my web host and get more traffic (and maybe a lot of FTP access and user shell accounts) Ken

  • RHEL raw device (over VMware RDM) performance issues

    - by jifa
    I'm running RHEL 5.3 over vSphere 4.0U1. I configured multiple LUNs on my NetApp (Fibre) storage, and added the RDM on two (Linux) VMs, using the Paravirtual SCSI adapter. One LUN is 100GB in size, successfully mapped to /dev/sdb on both VMs, 5 more are 500MB in size (mapped to /dev/sd{c-g}. I also created one partition per device. I have encountered two issues: First, writing directly to /dev/sdb1 gives me ~50MB/s, while any of the /dev/sd{c-g}1 gives me ~9MB/s. There is no difference in configuration of the LUNs apart from their size. I am wondering what causes this but this is not my main problem, as I would settle for 9 MB/s. I created raw devices using udev pretty straightforwardly: ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N" per device Writing to any of the new raw devices dramatically slows down performance to just over 900KB/s. Can anyone point me in a helpful direction? Thanks in advance, -- jifa

  • Loading Entities Dynamically with Entity Framework

    - by Ricardo Peres
    Sometimes we may be faced with the need to load entities dynamically, that is, knowing their Type and the value(s) for the property(ies) representing the primary key. One way to achieve this is by using the following extension methods for ObjectContext (which can be obtained from a DbContext, of course): 1: public static class ObjectContextExtensions 2: { 3: public static Object Load(this ObjectContext ctx, Type type, params Object [] ids) 4: { 5: Object p = null; 6:  7: EntityType ospaceType = ctx.MetadataWorkspace.GetItems<EntityType>(DataSpace.OSpace).SingleOrDefault(x => x.FullName == type.FullName); 8:  9: List<String> idProperties = ospaceType.KeyMembers.Select(k => k.Name).ToList(); 10:  11: List<EntityKeyMember> members = new List<EntityKeyMember>(); 12:  13: EntitySetBase collection = ctx.MetadataWorkspace.GetEntityContainer(ctx.DefaultContainerName, DataSpace.CSpace).BaseEntitySets.Where(x => x.ElementType.FullName == type.FullName).Single(); 14:  15: for (Int32 i = 0; i < ids.Length; ++i) 16: { 17: members.Add(new EntityKeyMember(idProperties[i], ids[i])); 18: } 19:  20: EntityKey key = new EntityKey(String.Concat(ctx.DefaultContainerName, ".", collection.Name), members); 21:  22: if (ctx.TryGetObjectByKey(key, out p) == true) 23: { 24: return (p); 25: } 26:  27: return (p); 28: } 29:  30: public static T Load<T>(this ObjectContext ctx, params Object[] ids) 31: { 32: return ((T)Load(ctx, typeof(T), ids)); 33: } 34: } This will work with both single-property primary keys or with multiple, but you will have to supply each of the corresponding values in the appropriate order. Hope you find this useful!

  • 3D physics engine for accurate collision handling on desktop/laptop computers (non-console)

    - by Georges Oates Larsen
    What are your suggestions for a physics engine that satisfies the following criteria? Capable of calculating collisions between multiple concave mesh-based colliders Handles many collisions going on at once (for instance one mesh being wedged between two others, which themselves may be wedged between two meshes) Does not allow for collider passthrough, even at high speeds. For instance, if I am applying force to a programmatically hinged object that makes it spin, I do not want it to pass through another rigidbody that it collides with while spinning. I have this problem using PhysX As implied before, reacts well to hinged objects, preferably has its own implementation of a hinge, but I am willing to program my own. The important part is that it has some sort of interface that guarantees accurate collision tracking even when dealing with these things Platform independent -- runs on mac as well as PC, also not tied down to specific graphics cards I think that's the best way to explain what I am looking for. Basically, I need SUPER reliable collisions. Something that can't be accomplished with a simple ray casting approach that sends a ray from the last position of the object to the current position (as this object may be potentially large and colliding with small objects via rotation) Bonus points for also including an OPEN SOURCE engine.

  • How to handle sorting of complex objects?

    - by AedonEtLIRA
    How would one sort a list of objects that have more than one sortable element? Suppose you have a simple object Car and car is a defined as such: class Car { public String make; public String model; public int year; public String color; // ... No methods, just a structure / container } I designed a simple framework that would allow for multiple SortOptions to be provided to a Sorter that would then sort the list. interface ISorter<T> { List<T> sort(List<T> items); void addSortOption(ISortOption<T> option); ISortOption<T>[] getSortOptions(); void setSortOption(ISortOption<T> option); } interface ISortOption<T> { String getLabel(); int compare(T t1, T t2); } Example use class SimpleStringSorter extends MergeSorter<String> { { addSorter(new AlphaSorter()); } private static final class AlphaSorter implements ISortOption<String> { // ... implementation of alpha compare and get label } } The issue with this solution is that it is not easily expandable. If car was to ever receive a new field, say, currentOwner. I would need to add the field, then track down the sorter class file, implement a new sort option class then recompile the application for redistribution. Is there an easier more expandable/practical way to sort data like this?

  • Dual Boot Win8 and Win7 - Win 7 fails while booting

    - by bjan
    Below are my dual boot settings. Both are on different partitions, default is Windows 8. Both were working fine. There are multiple users of this machine, few run 8 while few 7. All 7's users are novice and they use Internet only. I frequently update Windows 8 but not 7. Few weeks ago, Win 7 stopped booting. Machine gets restarted while booting with 7(Windows 7 start up glowing-Win-logo-screen does not appear) and the 8's loader reappears. Win 7's partition still exists and contains Windows folder What steps should i take to check the problem?

  • How can I setup a Firewall without NAT?

    - by SRobertJames
    We have 16 IP addresses from our ISP, and are setting up a SonicWall Firewall. I'd like to have the SonicWall do NAT for the LAN, but act as a firewall only (no NAT) for the servers which are using some of the 16 addresses. How do I set this up? If I set the WAN's subnet to include the 16 IPs, the SonicWall won't route the traffic to the LAN interface. Should I set the WAN subnet to only include the ones we are dedicating for NAT, and then keep the others on the LAN? Related point: How can I set multiple IP addresses for a SonicWall LAN interface?

  • How useful is PXE booting?

    - by J. T.
    Hi All, How fast is booting over PXE?. Is it conceivable to boot a linux installation? Does it take a long time? I have never really looked into it at all, but I was considering setting up a compiler farm and thought this might be interesting to try. Does one have a main computer that the PXE answers to to get its image? Can you have multiple PXE images to pick from? Thanks!

  • Testing a Virtualisation of a Debian Server (vmWare vSphere probably)

    - by xyza
    I'm soon getting access to a powerful root-server (quad-core, 16gb ram, 1gbit connection) where gameservers (like minecraft,counterstrike etc.) for different customers should be setup. My plan is to use programs such as vmWare vSphere to create some virtual machines for each customer. Inside such a virtual machine I'll setup the gameserver and maybe some kind of ftp server when its needed. Now that I'm kinda new to virtualisation of servers I want to test this local on my Desktop Computer. Is it possible to create a virtual machine of debian using vmWare Player on my Windows desktop computer and then install vmware vSphere in this VM to create multiple VM's inside that VM ? Or do I really need to install Debian on my desktop computer. (I want to use the time during installations etc. to work a bit at my windows installation) Some tips on virtualising debian servers are also appreciated :)

  • Am I the only one this anal / obsessive about code? [closed]

    - by Chris
    While writing a shared lock class for sql server for a web app tonight, I found myself writing in the code style below as I always do: private bool acquired; private bool disposed; private TimeSpan timeout; private string connectionString; private Guid instance = Guid.NewGuid(); private Thread autoRenewThread; Basically, whenever I'm declaring a group of variables or writing a sql statement or any coding activity involving multiple related lines, I always try to arrange them where possible so that they form a bell curve (imagine rotating the text 90deg CCW). As an example of something that peeves the hell out of me, consider the following alternative: private bool acquired; private bool disposed; private string connectionString; private Thread autoRenewThread; private Guid instance = Guid.NewGuid(); private TimeSpan timeout; In the above example, declarations are grouped (arbitrarily) so that the primitive types appear at the top. When viewing the code in Visual Studio, primitive types are a different color than non-primitives, so the grouping makes sense visually, if for no other reason. But I don't like it because the right margin is less of an aesthetic curve. I've always chalked this up to being OCD or something, but at least in my mind, the code is "prettier". Am I the only one?

  • Problems with Black Box KVM

    - by MrWizard54
    I just recieved a shipment of equipment orderd by my predicessor that includes brand new Dell Optiplex 990 computers, with standard mice and keyboards. Also included were Black Box ServSwitch Secure KVMs. I've worked with KVMs before and hypothetically they should be the easiest thing in the world to deal with, plug it all together, push the button, go. However, for the life of me I can't get the computers to recognize the mouse or keyboard when plugged into the KVM. We've seen this with multiple KVMs across the order. Any one know what I'm missing? Computers are all Dell 990 with Windows 7.

  • Shrinking physical volumes in LVM on a Linux Guest in ESXi 5.0

    - by Stew
    The problem: Linux guest (OpenSuse 12.1), with multiple virtual disks attached. 3 disks are in a logical volume, two of which are exactly 2TB. None of the disks are independent, and due to the backup software we use, cannot be independent. When the two 2TB virtual disks are "dependent", the snapshot fails stating that the file is too large for the datastore. When I put those two disks in independent mode, snapshots work fine (the other disk is 1.8TB). I have therefore concluded that even shrinking the two physical disks by 100GB should solve the problem, however I am having trouble conceptualizing how to go about getting those disks smaller without breaking the LVM entirely. The actual LV has 1.3TB free, so there is plenty of space to shrink with. What I need to accomplish: Deallocate 100GB from the two, 2TB virtual disks within the linux guest. Shrink the two virtual disks by 100GB within vsphere (not as complicated). Are there any vsphere/LVM gurus that can give me a clue?

  • jBullet Collision/Physics not working as expected

If I was to have multiple cubes in screen at once they all just sit there, or shoot off in all directions never stopping. Anyway, I am new to jBullet, and any help would be appreciated. // Constructor public Cube(float pX, float pY, float pZ, float pSize) { posX = pX; posY = pY; posZ = pZ; size = pSize; rotX = 0; rotY = 0; rotZ = 0; // physics stuff fallMotionState = new DefaultMotionState(new Transform(new Matrix4f(new Quat4f(0, 0, 0, 1), new Vector3f(posX, posY, posZ), 1))); fallRigidBodyCI = new RigidBodyConstructionInfo(mass, fallMotionState, fallShape, fallInertia); fallRigidBody = new RigidBody(fallRigidBodyCI); }

  • How to copy password from Mono-executed KeePass2 to xterm on Linux?

    - by Steve Emmerson
    I use KeePass2 to access username/password information in a Dropbox file. This allows convenient access from multiple devices. I can't seem to copy a password to the clipboard on my Linux 2.6.27.41-170.2.117.fc10.x86_64 system, however, in order to supply the password to a prompt in an xterm(1). I've tried both Ctrl+C/Ctrl+V and highlighting and mouse button 2 clicking. The KeePass2 program on the Linux system is executed by Mono. How can I copy the password to the xterm(1)? [Aside: I think we need a "KeePass" tag.] ADDENDUM: My mouse buttons were misconfigured: button 2 wasn't set to "copy". Sorry for the false alarm.

  • Running a command line app with sudo and password automatically on OS X startup

    - by Designer023
    I need to run an app at startup/login on my mac. I want it to launch in the background and start doing it's work without interrupting me or me having to start it up because I invariably forget and then when I need it, it wasn't running! I have tried using AppleScript to tell Terminal to run it and type my password in, but it ends up opening multiple Terminal windows and not working. Ideally I need a script that I can just add to the user login items and it will run for me. The app has no way of taking a password argument either and it has a password as well as the sudo! I need a solution that can either be done as an applescript (which can be made into an executable) or i need a commandline script but I have no idea about them. This is the manual code I type $ sudo serverStatus password:123456 password:serverpass My AppleScript: tell application Terminal activate do shell script "sudo serverStatus" delay 5 do shell script "123456" delay 2 do shell script "serverpass" end tell
