  • Running ssh-agent from a shell script

    - by Dan
    I'm trying to create a shell script that, among other things, starts up ssh-agent and adds a private key to the agent. Example: #!/bin/bash # ... ssh-agent $SHELL ssh-add /path/to/key # ... The problem with this is ssh-agent apparently kicks off another instance of $SHELL (in my case, bash) and from the script's perspective it's executed everything and ssh-add and anything below it is never run. How can I run ssh-agent from my shell script and keep it moving on down the list of commands?

  • 5 Design Tricks Facebook Uses To Affect Your Privacy Decisions

    - by Jason Fitzpatrick
    If you feel like Facebook increasingly has fewer and fewer options to reject applications and organization access to your private information, you’re not imagining it. Here are five ways Facebook’s design choices in the App Center have minimized your choices over time. Over at TechCrunch they have a guest post by Avi Charkham highlighting five ways recent changes to the Facebook App Center put privacy settings on the back burner. In regard to the comparison seen in the image above, for example, he writes: #1: The Single Button Trick In the old design Facebook used two buttons – “Allow” and “Don’t Allow” – which automatically led you to make a decision. In the new App Center Facebook chose to use a single button. No confirmation, no decisions to make. One click and, boom, your done! Your information was passed on to the app developers and you never even notice it. Hit up the link below to check out the other four redesign choices that minimize the information about privacy and data usage you see and maximize the click-through and acceptance rate for apps.

  • Character Stats and Power

    - by Stephen Furlani
    I'm making an RPG game system and I'm having a hard time deciding on doing detailed or abstract character statistics. These statistics define the character's natural - not learned - abilities. For example: Mass Effect: 0 (None that I can see) X20 (Xtreme Dungeon Mastery): 1 "STAT" Diablo: 4 "Strength, Magic, Dexterity, Vitality" Pendragon: 5 "SIZ, STR, DEX, CON, APP" Dungeons & Dragons (3.x, 4e): 6 "Str, Dex, Con, Wis, Int, Cha" Fallout 3: 7 "S.P.E.C.I.A.L." RIFTS: 8 "IQ, ME, MA, PS, PP, PE, PB, Spd" Warhammer Fantasy Roleplay (1st ed?): 12-ish "WS, BS, S, T, Ag, Int, WP, Fel, A, Mag, IP, FP" HERO (5th ed): 14 "Str, Dex, Con, Body, Int, Ego, Pre, Com, PD, ED, Spd, Rec, END, STUN" The more stats, the more complex and detailed your character becomes. This comes with a trade-off however, because you usually only have limited resources to describe your character. D&D made this infamous with the whole min/max-ing thing where strong characters were typically not also smart. But also, a character with a high Str typically also has high Con, Defenses, Hit Points/Health. Without high numbers in all those other stats, they might as well not be strong since they wouldn't hold up well in hand-to-hand combat. So things like that force trade-offs within the category of strength. So my original (now rejected) idea was to force players into deciding between offensive and defensive stats: Might / Body Dexterity / Speed Wit / Wisdom Heart Soul But this left some stat's without "opposites" (or opposites that were easily defined). I'm leaning more towards the following: Body (Physical Prowess) Mind (Mental Prowess) Heart (Social Prowess) Soul (Spiritual Prowess) This will define a character with just 4 numbers. Everything else gets based off of these numbers, which means they're pretty important. There won't, however, be ways of describing characters who are fast, but not strong or smart, but absent minded. Instead of defining the character with these numbers, they'll be detailing their character by buying skills and powers like these: Quickness Add a +2 Bonus to Body Rolls when Dodging. for a character that wants to be faster, or the following for a big, tough character Body Building Add a +2 Bonus to Body Rolls when Lifting, Pushing, or Throwing objects. [EDIT - removed subjectiveness] So my actual questions is what are some pitfalls with a small stat list and a large amount of descriptive powers? Is this more difficult to port cross-platform (pen&paper, PC) for example? Are there examples of this being done well/poorly? Thanks,

  • CMD Echo date but show month as string

    - by Asim Rehman
    I am using the robocopy command to create a backup system, I have successfully managed to copy the folders, but the date stamp is wrong. The folders are prefixed with the date and time . The robocopy command is this: robocopy U:\Data\ X:\Private\Backups\FolderName_%date:/=-%-(%time::=-%) /e The out of the folder is displayed like this: FolderName_09-11-2013-(20-24-06.60) The only thing I want to change is the date, I want to show the month as a string with only the first 3 characters like Oct. Can someone please guide me. Thanks.

  • Clipping polygons in XNA with stencil (not using spritebatch)

    - by Blau
    The problem... i'm drawing polygons, in this case boxes, and i want clip children polygons with its parent's client area. // Class Region public void Render(GraphicsDevice Device, Camera Camera) { int StencilLevel = 0; Device.Clear( ClearOptions.Stencil, Vector4.Zero, 0, StencilLevel ); Render( Device, Camera, StencilLevel ); } private void Render(GraphicsDevice Device, Camera Camera, int StencilLevel) { Device.SamplerStates[0] = this.SamplerState; Device.Textures[0] = this.Texture; Device.RasterizerState = RasterizerState.CullNone; Device.BlendState = BlendState.AlphaBlend; Device.DepthStencilState = DepthStencilState.Default; Effect.Prepare(this, Camera ); Device.DepthStencilState = GlobalContext.GraphicsStates.IncMask; Device.ReferenceStencil = StencilLevel; foreach ( EffectPass pass in Effect.Techniques[Technique].Passes ) { pass.Apply( ); Device.DrawUserIndexedPrimitives<VertexPositionColorTexture>( PrimitiveType.TriangleList, VertexData, 0, VertexData.Length, IndexData, 0, PrimitiveCount ); } foreach ( Region child in ChildrenRegions ) { child.Render( Device, Camera, StencilLevel + 1 ); } Effect.Prepare( this, Camera ); // This does not works Device.BlendState = GlobalContext.GraphicsStates.NoWriteColor; Device.DepthStencilState = GlobalContext.GraphicsStates.DecMask; Device.ReferenceStencil = StencilLevel; // This should be +1, but in that case the last drrawed is blue and overlap all foreach ( EffectPass pass in Effect.Techniques[Technique].Passes ) { pass.Apply( ); Device.DrawUserIndexedPrimitives<VertexPositionColorTexture>( PrimitiveType.TriangleList, VertexData, 0, VertexData.Length, IndexData, 0, PrimitiveCount ); } } public static class GraphicsStates { public static BlendState NoWriteColor = new BlendState( ) { ColorSourceBlend = Blend.One, AlphaSourceBlend = Blend.One, ColorDestinationBlend = Blend.InverseSourceAlpha, AlphaDestinationBlend = Blend.InverseSourceAlpha, ColorWriteChannels1 = ColorWriteChannels.None }; public static DepthStencilState IncMask = new DepthStencilState( ) { StencilEnable = true, StencilFunction = CompareFunction.Equal, StencilPass = StencilOperation.IncrementSaturation, }; public static DepthStencilState DecMask = new DepthStencilState( ) { StencilEnable = true, StencilFunction = CompareFunction.Equal, StencilPass = StencilOperation.DecrementSaturation, }; } How can achieve this? EDIT: I've just relized that the NoWriteColors.ColorWriteChannels1 should be NoWriteColors.ColorWriteChannels. :) Now it's clipping right. Any other approach?

  • How to automount SMB shared network drives in Mac OS X Lion

    - by cyppher
    In Mac OS X 10.7 (Lion) Apple has replaced good old SMB support. Now I can't auto connect to my shared (SMB) network drives. Workarounds? Or Impossible? In OS X Snow Leopard, I could automatically connect my Ubuntu (SMB) shared network drives with auto_smb / auto_master (autofs configuration in /private/etc/). I made three mount points (folders) directly in '/Volumes', I used /Volumes/Data and /Volumes/webroot (both SMB shared). Unfortunately Lion doesn't connect (automount) my network drives. I have to manually connect to the server (Ubuntu file server) in Finder, then open up Terminal to navigate to the mount points, and then it connects. This is not a workable solution. I've searched (Google/SO) but found no solutions apart from an unsupported hack. Isn't it possible any more to automatically connect to an SMB-shared drive during startup?

  • How to get OpenSSH to use ksshaskpass under KDE?

    - by Guss
    When using a GNOME desktop on Ubuntu, if I use OpenSSH client to connect to another computer (running from the gnome-terminal), I get a single graphic popup asking for my private key's pass-phrase. After that I no longer need to enter my pass-phrase as it is cached by the SSH agent. Under KDE it doesn't work like that - when I start ssh from konsole, I get a text prompt for my pass-phrase every single time, even though ssh-agent is running. If I run ssh-add from the terminal then I can enter my pass-phrase on the terminal and it will be stored by ssh-agent and I won't get any more pass-phrase prompts, while if I run ssh-add the KRunner graphical command line ("Run" dialog) then I get a graphical prompt with the same behavior. The problem is I have to remember running ssh-add every time I log in to the desktop. How can I get ssh to behave under KDE, the same as it does on GNOME - the first time the pass-phrase is needed, pop up a graphical dialog and store the pass-phrase in the agent. I've installed ksshaskpass, but that didn't change anything.

  • What type of VPS stats should I look for?

    - by Dave
    I have a few websites that average a total of 10,000 uniques a day across my network. I also have a few mobile apps that pull xml data maybe 5,000 calls a day. My sites aren't anything major just a few wallpaper websites and few other small sites, nothing real database intensive. I currently own a dedicated server and I feel like it's overkill for my network. I'm looking into getting a Virtual Private Server (VPS). I was just wondering what kind of stats I should be looking for to support my network of sites. Thanks

  • What are my options for sharing music between Windows & Ubuntu on the same network?

    - by jgbelacqua
    We have a few Windows(XP & 7) and Ubuntu machines in the house sharing a wireless connection, and want to share music between them. If possible, I would like to be able to serve music from both Windows and Ubuntu (but it doesn't have to be the same time). I don't know much about sharing folders or streaming, but I'm guessing both would be options (that is, using a local client to access a shared song or a local client to access a shared stream). I want to be able to share the music between the systems as simply as possible. Bonus points (but not requirements) for cross-platform -- same application on both Windows and Ubuntu? available on startup (via daemon or autostart or whatnot) open source More info: All systems have dynamic addresses (DHCP) supplied from the ISP-supplied wireless router. There are several Gigabytes of music on one Windows XP box and one Ubuntu 10.10 The music is not well-sorted (I'm thinking this might have an impact on UI usability). Only has to be available internally (private address space behind the wireless router) bandwidth is not a problem We don't have (legitimate) admin access to the wireless router

  • Single Responsibility Principle - How Can I Avoid Code Fragmentation?

    - by Dean Chalk
    I'm working on a team where the team leader is a virulent advocate of SOLID development principles. However, he lacks a lot of experience in getting complex software out of the door. We have a situation where he has applied SRP to what was already quite a complex code base, which has now become very highly fragmented and difficult to understand and debug. We now have a problem not only with code fragmentation, but also encapsulation, as methods within a class that may have been private or protected have been judged to represent a 'reason to change' and have been extracted to public or internal classes and interfaces which is not in keeping with the encapsulation goals of the application. We have some class constructors which take over 20 interface parameters, so our IoC registration and resolution is becoming a monster in its own right. I want to know if there is any 'refactor away from SRP' approach we could use to help fix some of these issues. I have read that it doesn't violate SOLID if I create a number of empty courser-grained classes that 'wrap' a number of closely related classes to provide a single-point of access to the sum of their functionality (i.e. mimicking a less overly SRP'd class implementation). Apart from that, I cannot think of a solution which will allow us to pragmatically continue with our development efforts, while keeping everyone happy. Any suggestions ?

  • Choosing between cloud (Cloudfoundry ) and virtual servers - for developers

    - by Mike Z
    I just came across some articles on how to setup your own cloud using Cloudfoundry and Ubuntu, this got me thinking, choosing our infrastructure, if we want to use our own servers what's the advantage of cloud on virtual servers vs just using virtual servers, VPN? If we now develop for the cloud later if we need help we can quickly move on to a cloud provider, but other than that what's the advantage and disadvantage of private cloud in these areas? speed of development, testing, deployment server management security having an extra layer (cloud) will that have a hit on server performance, how big? any other advantage/disadvantage?

  • How to Be a Software Engineer?

    - by Mistrio
    My problem is kind of weird so please bear with me. I have been working in a start up concerned basically with mobile development since my graduation 2 years ago. I develop apps for iOS but it's not really relevant. The start up structure is simply founders developers, with no middle-tier technical supervision or project management whatsoever. A typical project cycle of ours is like this: meet with a client send very vague recruitment to an outsourced graphics designer dig in development right after we get the design, no questions asked then improvise improvise improvise! It's not that we are unaware that stuff like requirements analysis, UML, design patterns, source code control, testing, development methodologies... etc. exist, we just simply don't use them, and I mean like never. The result is usually a clunk of hardly-maintainable yet working code. Despite everything we are literally flourishing with many successful apps on all platforms and bigger clients each project. The thing is, we want the chaos and we're looking for advice. How would you fix our company technically? Given that you can't hire project managers or team leaders just because we are barely 5 developers, so it wouldn't be a justified cost for the founders, but one-time things like courses, books, private training... etc is an option. Lastly, if it's relevant, we are based in Egypt. Thank you a lot in advance.

  • Optimizing MySQL -

    - by Josh
    I've been researching how to optimize MySQL a bit, but I still have a few questions. MySQL Primer Results http://pastie.org/private/lzjukl8wacxfjbjhge6vw Based on this, the first problem seems to be that the max_connections limit is too low. I had a similar problem with Apache initially, the max connection limit was set to 100, and the web server would frequently lock up and take an excruciatingly long time to deliver pages. Raising the connection limit to 512 fixed this issue, and I read that raising the connection limit on MySQL to match this was considered good practice. Being that MySQL has actually been "locking up" recently as well (connections have been refused entirely for a few minutes at a time at random intervals) I'm assuming this is the main cause of the issue. However, as far as table cache goes, I'm not sure what I should set this as. I've read that setting this too high can hinder performance further, so should I raise this to right around 551, 560, 600, or do something else? Lastly, as far as raising the join_buffer_size value goes, this doesn't even seem to be included in Debian's my.cnf file by default. Assuming there's not much I can do about adding indexes, should I look into raising this? Any suggested values? Any suggestions in general here would be appreciated as well. Edit: Here's the number of open tables the MySQL server is reporting. I believe this value is related to my question (Opened_tables: 22574)

  • public key always asking for password and keyphrase

    - by Andrew Atkinson
    I am trying to SSH from a NAS to a webserver using a public key. NAS user is 'root' and webserver user is 'backup' I have all permissions set correctly and when I debug the SSH connection I get: (last little bit of the debug) debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password debug1: Next authentication method: publickey debug1: Offering DSA public key: /root/.ssh/id_dsa.pub debug1: Server accepts key: pkalg ssh-dss blen 433 debug1: key_parse_private_pem: PEM_read_PrivateKey failed debug1: read PEM private key done: type <unknown> Enter passphrase for key '/root/.ssh/id_dsa.pub': I am using the command: ssh -v -i /root/.ssh/id_dsa.pub [email protected] The fact that it is asking for a passphrase is a good sign surely, but I do not want it to prompt for this or a password (which comes afterwards if I press 'return' on the passphrase)

  • Restricted blogspot account. Unable to subscribe using Google Reader?

    I used blogspot.com and restricted its viewership to just its authors. However I cannot use Google Reader to subscribe to the RSS feed. Is there a workaround? I need to be notified somehow whenever somebody posts to that private blog. I am one of its authors. My blogspot.com allows me to set the readership to just its authors. So that is what I have done. I did not do any password protect settings at all.

  • Static classes and/or singletons -- How many does it take to become a code smell?

    - by Earlz
    In my projects I use quite a lot of static classes. These are usually classes that naturally seem to fit into a single-instance type of thing. Many times I use static classes and recently I've started using some singletons. How many of these does it take to become a code smell? For instance, in my recent project which has a lot of static classes is an Authentication library for ASP.Net. I use a static class for a helper class that fixes ASP.Net error codes so it can be used like CustomErrorsFixer.Fix(Context); Or my authentication class itself is a static class //in global.asax's begin_application Authentication.SomeState="blah"; Authentication.SomeOption=true; //etc //in global.asax's begin_request Authentication.Authenticate(); When are static or singleton classes bad to use? Am I doing it wrong, or am I just in a project that by definition has very little per-instance state associated with it? The only per-instance state I have is stored in HttpContext.Current.Items like so: /// <summary> /// The current user logged in for the HTTP request. If there is not a user logged in, this will be null. /// </summary> public static UserData CurrentUser{ get{ return HttpContext.Current.Items["fscauth_currentuser"] as UserData; //use HttpContext.Current as a little place to persist static data for this request } private set{ HttpContext.Current.Items["fscauth_currentuser"]=value; } }

  • Improving the speed of writing code in C#

    - by Robert Harvey
    Laugh if you want, but I used to develop substantial line-of-business applications in VB6, long before the .NET framework came along. Why, when I was your age, we used to walk two miles in the snow, uphill. Both ways... Love it or hate it, VB6 had a REPL-like feel, and a very rapid development cycle. I would like to know how to come closer to that process in C#. In VB6, I could write a function, execute it, debug it and have it fully functional in a few minutes. I am told this is how the Lisp crowd works. It's a very rapid-fire style of programming. In C# I write a function, then I write a unit test for that function (which is OK, I understand the value of that), then I right-click, run test, wait for the project to compile (takes about 10 seconds right now, which would be an eternity for a REPL loop), and get an exception. Honestly, this feels more like my junior college days, when I used to feed punch cards into a hopper and wait for a printout (exaggerating only slightly for effect). Additionally, my tendency nowadays is to make everything public while I'm testing it. Unit testing with private accessors works fine, but you can't trace through the code (unless, of course, I'm doing something wrong) while you're using them. So what I'd like to know is, what adjustments have you made to your development process in C# to streamline it, and make it possible to write and verify your code very rapidly?

  • Help me a routing server on Windows XP

    - by Lu Lu
    I am developing client/server applications and need to test them on Internet environment. However, I only have one PC without connecting the public internet, so I have a plan to simulate a virtual internet environment on my PC. I think I will install the virtual machines for my purpose, but I can install only one machine because of my slowly PC. At the moment, my PC has 2 machines: the host machine (use Windows XP) & the virtual machine (use Windows Server 2003 Ent). Each machine will have 2 network adapter (host-only & internal), and in 2 network adapters, the internal adapter is private on each machine, and host-only adapters are connected together. With Windows 2003, routing server is ok, but I wonder on Windows XP, are there any routing server product? Please help me. Thanks.

  • Generic Repository with SQLite and SQL Compact Databases

    - by Andrew Petersen
    I am creating a project that has a mobile app (Xamarin.Android) using a SQLite database and a WPF application (Code First Entity Framework 5) using a SQL Compact database. This project will even eventually have a SQL Server database as well. Because of this I am trying to create a generic repository, so that I can pass in the correct context depending on which application is making the request. The issue I ran into is my DataContext for the SQL Compact database inherits from DbContext and the SQLite database inherits from SQLiteConnection. What is the best way to make this generic, so that it doesn't matter what kind of database is on the back end? This is what I have tried so far on the SQL Compact side: public interface IRepository<TEntity> { TEntity Add(TEntity entity); } public class Repository<TEntity, TContext> : IRepository<TEntity>, IDisposable where TEntity : class where TContext : DbContext { private readonly TContext _context; public Repository(DbContext dbContext) { _context = dbContext as TContext; } public virtual TEntity Add(TEntity entity) { return _context.Set<TEntity>().Add(entity); } } And on the SQLite side: public class ElverDatabase : SQLiteConnection { static readonly object Locker = new object(); public ElverDatabase(string path) : base(path) { CreateTable<Ticket>(); } public int Add<T>(T item) where T : IBusinessEntity { lock (Locker) { return Insert(item); } } }

  • Default Parameter in .NET 4(C#)

    - by Yousef_Jadallah
    During my using for the new release .NET 4, I notice that C# support default (Optional) Parameters, after thousands of complains form C# programmer- especially it was supported by VB.NET- now it's available. Let's create Test function with Optional Parameter   private void TestFunction(string para1, string para2 = "Default") { Response.Write("Parameter one =" + para1 +" , Parameter two="+ para2 ); } Then, if you try to call this method the Intellisense display likes this:   .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   Therefore,if you don’t pass the second parameter the value of para2 will be “Default”. With this new future in C#, you can ignore many overload functions event it was acceptable solution!

  • Best practice settings Effect parameters in XNA

    - by hichaeretaqua
    I want to ask if there is a best practice settings effect parameters in XNA. Or in other words, what exactly happens when I call pass.Apply(). I can imagine multiple scenarios: Each time Apply() is called, all effect parameters are transferred to the GPU and therefor it has no real influence how often I set a parameter. Each time Apply() is called, only the parameters that got reset are transferred. So caching Set-operations that don't actually set a new value should be avoided. Each time Apply() is called, only the parameters that got changed are transferred. So caching Set-operations is useless. This whole questions is bootless because no one of the mentions ways has any noteworthy impact on game performance. So the final question: Is it useful to implement some caching of Set-operation like: private Matrix _world; public Matrix World { get{ return _world;} set { if(value == world)return; _effect.Parameters["xWorld"].SetValue(value); _world = value; } Thanking you in anticipation

  • Thoughts on iPhone, Flash, IE

    - by guybarrette
    It’s interesting to see the debate caused by the iPhone debate over Flash.  In the new version of the iPhone Developer Program License Agreement, Apple bans Flash and Monotouch: 3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited). In Adobe’s last SEC filing, they list the iPhone/iPad as a threat to their business. http://www.sec.gov/Archives/edgar/data/796343/000079634310000007/form_10q.htm#riskfactors We offer our desktop application-based products primarily on Windows and Macintosh platforms. We generally offer our server-based products on the Linux platform as well as the Windows and UNIX platforms. To the extent that there is a slowdown of customer purchases of personal computers on either the Windows or Macintosh platform or in general, to the extent that we have difficulty transitioning product or version releases to new Windows and Macintosh operating systems, or to the extent that significant demand arises for our products or competitive products on other platforms before we choose and are able to offer our products on these platforms our business could be harmed. Additionally, to the extent new releases of operating systems or other third-party products, platforms or devices, such as the Apple iPhone or iPad, make it more difficult for our products to perform, and our customers are persuaded to use alternative technologies, our business could be harmed. I had a conversation recently about IE9 and people were asking why is Microsoft spending money and resources to build IE9 now that we have Silverlight.  It makes just no sense to put so much efforts to support HTML 5 in IE because it’s overlapping with Silverlight, no?  Well, what if Chrome became the dominant browser and all of a sudden, Google would remove the object tag?  Would Microsoft be in the same position as Adobe is right now on the iPhone? What do you think? var addthis_pub="guybarrette";

    Hi there, I want to access a web application running on a web server behind my office firewall from an external machine. We have a bastion host running sshd that is accessible from the Internet. I want to know if this solution is a bad idea: Create an account on the bastion host with shell=/bin/false and no password ('testuser') Create a ssh RSA key on the external machine Add the public RSA key to the testuser's authorized_keys file ssh to the bastion host from the external host using: ssh -N 8888:targethost:80 run my tests from the external host shut down the ssh tunnel I understand that if my RSA private key were compromised then someone could ssh to the bastion host. But are there other reasons this solution is a bad idea? thank you!
