  • What would be the fastest way of storing or calculating legal move sets for chess pieces?

    - by ioSamurai
    For example if a move is attempted I could just loop through a list of legal moves and compare the x,y but I have to write logic to calculate those at least every time the piece is moved. Or, I can store in an array [,] and then check if x and y are not 0 then it is a legal move and then I save the data like this [0][1][0][0] etc etc for each row where 1 is a legal move, but I still have to populate it. I wonder what the fastest way to store and read a legal move on a piece object for calculation. I could use matrix math as well I suppose but I don't know. Basically I want to persist the rules for a given piece so I can assign a piece object a little template of all it's possible moves considering it is starting from it's current location, which should be just one table of data. But is it faster to loop or write LINQ queries or store arrays and matrices? public class Move { public int x; public int y; } public class ChessPiece : Move { private List<Move> possibleMoves { get; set; } public bool LegalMove(int x, int y){ foreach(var p in possibleMoves) { if(p.x == x && p.y == y) { return true; } } } } Anyone know?

  • Best VoIP VPS Location?

    - by ToiletOverflow
    Our office currently runs a few phones over a VoIP line. Through our VoIP provider, we have a virtual private server. We chose them as the VPS provider because the VPS came pre-loaded with all of the software that was necessary. However, I've discovered that I would rather manage the software myself and would prefer to work on a different platform. The primary reason that we have stayed with them is because as our VoIP provider, I presume that there is some advantage in call quality because they have "direct access to the PSTN", which I would presume is an advantage when it comes to call termination and overall call quality. My question boils down to: What is better from a call quality perspective? 1) A server located 20ms closer to us (60ms), offered by a different company. 2) The current server at the VoIP/SIP provider (80ms)

  • Prevent URLs from specific domains from being saved in Firefox history

    - by noam
    I want to prevent or block URLs of specific domains from being saved or shown in my history. I want to be able to go to these certain websites normally, just not have them saved and not have to use private or incognito mode. For instance, I don't want any of Google's search result pages to be saved in my history since then when I use the awesomebar I get a lot of Google's search results, which are of no use to me. Of course I can keep on deleting them, but I would like a way to specify that any URL starting with www.google.com shouldn't be saved.

  • College Ratings via the Federal Government

    - by user9147039
    A few weeks back you might remember news about a higher education rating system proposal from the Obama administration. As I've discussed previously, political and stakeholder pressures to improve outcomes and increase transparency are stronger than ever before. The executive branch proposal is intended to make progress in this area. Quoting from the proposal itself, "The ratings will be based upon such measures as: Access, such as percentage of students receiving Pell grants; Affordability, such as average tuition, scholarships, and loan debt; and Outcomes, such as graduation and transfer rates, graduate earnings, and advanced degrees of college graduates.” This is going to be quite complex, to say the least. Most notably, higher ed is not monolithic. From community and other 2-year colleges, to small private 4-year, to professional schools, to large public research institutions…the many walks of higher ed life are, well, many. Designing a ratings system that doesn't wind up with lots of unintended consequences and collateral damage will be difficult. At best you would end up potentially tarnishing the reputation of certain institutions that were actually performing well against the metrics and outcome measures that make sense in their "context" of education. At worst you could spend a lot of time and resources designing a system that would lose credibility with its "customers". A lot of institutions I work with already have in place systems like the one described above. They are tracking completion rates, completion timeframes, transfers to other institutions, job placement, and salary information. As I talk to these institutions there are several constants worth noting: • Deciding on which metrics to measure is complicated. While employment and salary data are relatively easy to track, qualitative measures are more difficult. How do you quantify the benefit to someone who studies in one field that may not compensate him or her as well as another field but that provides huge personal fulfillment and reward is a difficult measure to quantify? • The data is available but the systems to transform the data into actual information that can be used in meaningful ways are not. Too often in higher ed information is siloed. As such, much of the data that need to be a part of a comprehensive system sit in multiple organizations, oftentimes outside the reach of core IT. • Politics and culture are big barriers. One of the areas that my team and I spend a lot of time talking about with higher ed institutions all over the world is the imperative to optimize for student success. This, like the tracking of the students’ achievement after graduation, requires a level or organizational capacity that does not currently exist. The primary barrier is the culture of "data islands" in higher ed, and the need for leadership to drive out the divisions between departments, schools, colleges, etc. and institute academy-wide analytics and data stewardship initiatives that will enable student success. • Data quality is a very big issue. So many disparate systems exist (some on premise, some "in the cloud") that keep data about "persons" using different means to identify them. Establishing a single source of truth about an individual and his or her data is difficult without some type of data quality policy and tools. Good tools actually exist but are seldom leveraged. Don't misunderstand - I think it's a great idea to drive additional transparency and accountability into the system of higher education. And not just at home, but globally. Students and parents need access to key data to make informed, responsible choices. The tools exist to not only enable this kind of information to be shared but to capture the very metrics stakeholders care most about and in a way that makes sense in the context of a given institution's "place" in the overall higher ed panoply.

  • Consultations with ATG Development at OpenWorld 2014

    - by Steven Chan (Oracle Development)
    Our OpenWorld 2014 San Francisco conference is about six weeks away.  We have a great lineup of sessions this year.  Our EBS Applications Technology track sessions are listed here, and we'll have a more-detailed article about those soon. One of the advantages of attending OpenWorld is that you can meet face-to-face with senior staff in ATG Development.  You can use these meetings to discusss your questions, requirements, plans, and deployment architectures with us. There are several options for doing this: At general sessions: collar the speaker of your choice after his or her presentation. At the Meet The Experts sessions:  these are first-come first-served round-table discussions Setting up private meetings via your Oracle account manager The last option is best if you have lots of in-depth questions or confidential details about your implementation that cannot be discussed in front of other customers.  Many of this blog's experts, including me, will be attending OpenWorld this year.  If you'd like to meet with us privately, please contact your Oracle account manager to arrange that as soon as possible.  My calendar, in particular, is already starting to fill up.  It is often completely full by the time OpenWorld starts. See you there!

  • Unnamed Refactoring

    - by Liam McLennan
    This post is a message in a bottle. It cast it into the sea in the hope that it will one day return to me, stuffed to the cork with enlightenment. Yesterday I  tweeted, what is the name of the pattern where you replace a multi-way conditional with an associative array? I said ‘pattern’ but I meant ‘refactoring’. Anyway, no one replied so I will describe the refactoring here. Programmers tend to think imperatively, which leads to code such as: public int GetPopulation(string country) { if (country == "Australia") { return 22360793; } else if (country == "China") { return 1324655000; } else if (country == "Switzerland") { return 7782900; } else { throw new Exception("What ain't no country I ever heard of. They speak English in what?"); } } which is horrid. We can write a cleaner version, replacing the multi-way conditional with an associative array, treating the conditional as data: public int GetPopulation(string country) { if (!Populations.ContainsKey(country)) throw new Exception("The population of " + country + " could not be found."); return Populations[country]; } private Dictionary<string, int> Populations { get { return new Dictionary<string, int> { {"Australia", 22360793}, {"China", 1324655000}, {"Switzerland", 7782900} }; } } Does this refactoring already have a name? Otherwise, I propose Replace multi-way conditional with associative array

  • Recommend a web file sharing software please.

    - by Baczek
    I'm looking for a web platform to put company files at. My requirements are: should be accessible via a browser should be open source must be installable (dropbox is a no-go) must have an option to put a access time limit on a file must perform garbage collection automatically after a file expires must be able to mark files as public or private an option to protect a file via a pin-code for users without accounts in the system would be nice to have The problem is I don't even know what to search for - all my googling results in either complete groupware solutions or p2p file sharing software. If such a thing doesn't exist, please don't hestitate to say so, so I can crawl to a corner and cry myself to sleep. TIA

  • Running Tomcat 7 and Apache 2 on the same server

    - by Thorn
    Part of my site needs to run over HTTPS and I'm creating a sub-domain for that part. I have apache httpd 2 AND Tomcat 7 running on the same server with the same IP, Apache is on port 80 of course, while Tomcat is running on port 8080. Right now I am doing domain forwarding for requests that need to run off tomcat. For example, mathteamhosting.com/mathApp can forward to mathteamhosting.com:8080/mathApp. I would like to have Tomcat handle the https requests for that subdomain. I don't think this forwarding technique can work in this case. How do I set that up so that Tomcat receives the requests on port 443 while apache handles port 80. To be more specific: http://proctinator.com == request goes to Apache web server https://private.proctinator.com == request goes to Apache web server

  • How to merge several detached signatures from different people into one?

    - by Petr Pudlák
    A group of people wants to publish a file and they all want to digitally sign the file as different recipients of the file will have different chains of trust. For simplicity, it's desired that there is only one detached signature file with all the signatures, so that the recipients don't need to check them one by one: foo.tar.gz foo.tar.gz.sig However, for security reasons, every person needs to perform the signing on their computer, it's not possible to create the combined signature by having multiple private keys on one computer and performing the operation with one command. Is it possible with GPG to somehow merge detached signatures of a file from multiple participants?

  • How to import Exchange calendars in Google Calendar (No Desktop Outlook)

    - by Tonny Madsen
    I would like to import my calendar from my company Exchange 2010 server as a new calendar in my private Google account. The primary use is to easy my planning when at home with my laptop. I already have access to both the Google and Exchange calendars on my Android phone, but the size of the screen makes it rather difficult to plan anything serious. Note that I run OSX on my laptop I would prefer a Internet based solution to any software on my own laptop. I do not want an Outlook add-in I do not want to include the work related events in my main calendar I do not want a mobile solution I can pay for the solution

  • Windows Vista Home memory usage problem

    - by lordg
    Hi, I have a Windows Vista Home laptop from a client that is running on 1GB ram. The laptop is used for super basic things, word, internet, outlook, etc. What makes zero sense is that the RAM is being completely consumed, causing the PC to hang sometimes when it can't take it anymore. However, in task manager, the processes appear to only be consuming maybe 100MB (Private Working Set). The client literally has a simple setup, and is running kaspersky, though that does not seem to be indicating it is the cause of the excessive memory usage. Does anyone have a suggestion on how to resolve the memory issue or how to track down what is actually happening and fix it? G

  • How do I draw a 2d plane and rotate camara (To be a board) in a 3d XNA game?

    - by Mech0z
    I am trying to create a simple board game, but the 3d part of this is really killing me. From what I can gather I have created a plane, but it never moves even though I turn the camara, but that partially makes sense as I only turn the camara with a 3d model, but in my head that makes 0 sense, in my head if I turn the camara it should affect ALL my models? But with this code the camara only "cares" about the 3d cylinder, the plane is just completely still private void OnDraw(object sender, GameTimerEventArgs e) { SharedGraphicsDeviceManager.Current.GraphicsDevice.Clear(Color.CornflowerBlue); foreach (ModelMesh mesh in cylinderModel.Meshes) { foreach (BasicEffect effect in mesh.Effects) { //effect.World = Matrix.CreateRotationX((float)e.TotalTime.TotalSeconds * 2); effect.View = Matrix.CreateLookAt(cameraPosition, Vector3.Zero, Vector3.Up); effect.Projection = Matrix.CreatePerspectiveFieldOfView(MathHelper.ToRadians(45.0f), aspectRatio, 1.0f, 10000.0f); effect.EnableDefaultLighting(); } mesh.Draw(); } //cameraPosition.Z -= 5.0f; _effect.World = Matrix.CreateRotationZ((MathHelper.ToRadians(((float)e.TotalTime.Milliseconds / 2) % 360))); foreach (EffectPass pass in _effect.CurrentTechnique.Passes) { pass.Apply(); SharedGraphicsDeviceManager.Current.GraphicsDevice.DrawUserPrimitives(PrimitiveType.TriangleStrip, _vertices, 0, 1, VertexPositionColor.VertexDeclaration); } } Is there a way to get the camara to affect all models?

  • How to generate new CSRs for TLS use in sendmail?

    - by Mikey B
    SendMail 8.13.8 | CentOS 5.x Hi Guys, I'm using ca-signed TLS certificates on my sendmail server and they are up for renewal soon. Our new CA doesn't like our old CSR so I need to generate a new CSR. Can someone point me to the procedure for doing this (without affecting the production certs that are already in use)? I'm paranoid of overwriting the old TLS certs in the process of generating a CSR. Most of the instructions I've found are for implementing self-signed TLS certs -- which isn't an option for me at this time. I'm thinking it would something like: openssl req -new -nodes -out new-tls.csr -keyout new-tls-private.key But I wasn't sure if I was missing some options there such as the -x509 option... -M

  • Postfix not delivering mails

    - by Sotocan
    I have problems with a recently configured postfix MTA. When postfix starts the following warning appears: "postfix/qmgr[5078]: warning: connect to transport private/filter: No such file or directory" I have amavis-new as a content-filter, but even if I comment-out the relevant line, the warning appears. As a result (I think), of the above, I get errors like below, for every virtual domain that I have: "postfix/error[5080]: 254851834107: to=, relay=none, delay=13082, delays=13082/0.01/0/0.01, dsn=4.3.0, status=deferred (mail transport unavailable)" The good news for me, is that somehow I managed to fix that (don't ask me how!!!!) The problem is that now I have 50 or so mails, that were affected by the aforementioned problem, in the mail-queue... If I "postqueue -f " I get the same style of error as before (mail transport unavailable)...however new mails are delivered to their final destination properly... Any suggestions? Kind regards. P.S. Local mail delivery from/to Unix and virtual users, was OK write from the beginning!

  • When using MVVM, should you create new viewmodels, or swap out the models?

    - by ConditionRacer
    Say I have a viewmodel like this: public class EmployeeViewModel { private EmployeeModel _model; public Color BackgroundColor { get; set; } public Name { get { return _model.Name; } set { _model.Name = value; NotifyPropertyChanged(Name); } } } So this viewmodel binds to a view that displays an employee. The thing to think about is, does this viewmodel represent an employee, or a "displayable" employee. The viewmodel contains some things that are view specific, for instance the background color. There can be many employees, but only one employee view. With this in mind, when changing the displayed employee, does it make sense to create a new EmployeeViewModel and rebind to the view, or simply swap out the EmployeeModel. Is the distinction even important, or is it a matter of style? I've always leaned toward creating new viewmodels, but I am working on a project where the viewmodels are created once and the models are swapped out. I'm not sure how I feel about this, though it seems to work fine.

  • How to use ssh-agent (and graphic passphrase dialog) in Kubuntu 10.10?

    - by halo
    I have recently switched from Ubuntu to kubuntu, both version 10.10. Unfortunately in KDE the ssh passphrase dialog doesn't work out of the box. Everytime my ssh private key is used I need to enter my password. This is neither secure nor comfortable. I have done comprehensive research on the net but only found out dated documentation. Several things I tried didn't work out. Current status: SSH setup working with direct passphrase input ssh-agent running in X session $SSH_AUTH_SOCK set to ssh-agent's socket in X session How to enable ssh-agent for keeping the passphrase in memory for ~15mins and as a bonus always use a graphical dialog for its input? I use asymmetric SSH key pairs for pushing/pulling in Git VCS logging remotely into different server systems

  • How to define implementation details?

    - by woni
    In our project, an assembly combines logic for the IoC-Container, the project internals and the communication layer. The current version evolved to have only internal classes in addin assemblies. My main problem with this approach is, that the entry point is only available over the IoC-Container. It is not possible to use anything else than reflection to initialize the assembly. Everything behind the IoC-Interface is defined as implementation detail and therefore not intended for usages outside. It is well known that you should not test implementation detail (such as private and internal methods), because they should be tested through the public interface. It is also well known, that your tests should not use the IoC-Container to setup the SUTs, because that would result in too much dependencies. So we are using the InternalsVisibleTo-Attribute to make internals visible to our test assemblies and test the so called implementation details. I recognized that one problem could be the mixup between different concerns in that assembly, changing this would make this discussion useless, because classes have to be defined public. Ignoring my concerns with this, isn't the need to test a class enough reason to make it public, the usages of InternalsVisibleTo seems unintended, and a little bit "hacky". The approach to test only against the publicly available IoC-Container is too costly and would result in integration style tests. The pros of using internals are, that the usages are well known and do not have to be implemented like a public method would have to be (documentation, completeness, versioning,...). Is there a solution, to not test against internals, but keep their advantages over public classes, or do we have to redefine what an implementation detail is.

  • Virtual bridge/switch for Windows server&client?

    - by Tiberiu-Ionu? Stan
    I can't find a very simple application, with litle to zero configuration on both client and server side which would help one computer to bring other computers on an existing private LAN. OpenVPN seems like an overkill for this type of thing, and is really hard to get running or debug by various clueless people trying to connect. Does such a software exist? It's very odd not to. THe Windows provided VPN (PPTP over TCP and GRE) is not what I'm looking for because it is often filtered by ISPs. Only TCP and UDP solutions pls. Encryption is not needed.

  • Why is file sharing over internet still working, despite all firewall exceptions for filesharing being disabled?

    - by Triynko
    Every exception in my windows server firewall that starts with "File and Printer Sharing" is disabled (ordered by name, so that includes domain, public (active), and private profiles). The Network and Sharing Center's options for everything except password protected sharing are off. Why would I still be able to access a network share on that server via an address like "\\my.server.com\" over the internet? The firewall is on for all profiles and blocking incoming connections by default. A "netstat -an" command on the server reveals the share connection is occurring over port 445 (SMB). I restarted the client to ensure it was actually re-establishing a new connection successfully. Is the "Password protected sharing: On" option in Network and Sharing Center bypassing the firewall restrictions, or adding some other exception somewhere that I'm missing? EDIT: "Custom" rules are not the problem. It's the "built-in" rules for Terminal Services that was the problem. Can you believe port 445 (File Sharing Port) has to be wide open to the internet to use Terminal Services Licensing?)

  • Throwing and catching exceptions in the same function/method

    - by usr
    I've written a function that asks a user for input until user enters a positive integer (a natural number). Somebody said I shouldn't throw and catch exceptions in my function and should let the caller of my function handle them. I wonder what other developers think about this. I'm also probably misusing exceptions in the function. Here's the code in Java: private static int sideInput() { int side = 0; String input; Scanner scanner = new Scanner(System.in); do { System.out.print("Side length: "); input = scanner.nextLine(); try { side = Integer.parseInt(input); if (side <= 0) { // probably a misuse of exceptions throw new NumberFormatException(); } } catch (NumberFormatException numFormExc) { System.out.println("Invalid input. Enter a natural number."); } } while (side <= 0); return side; } I'm interested in two things: Should I let the caller worry about exceptions? The point of the function is that it nags the user until the user enters a natural number. Is the point of the function bad? I'm not talking about UI (user not being able to get out of the loop without proper input), but about looped input with exceptions handled. Would you say the throw statement (in this case) is a misuse of exceptions? I could easily create a flag for checking validity of the number and output the warning message based on that flag. But that would add more lines to the code and I think it's perfectly readable as it is. The thing is I often write a separate input function. If user has to input a number multiple times, I create a separate function for input that handles all formatting exceptions and limitations.

  • How to hide a program that is running on a virtual machine?

    - by Femto Trader
    Some softwares contain tests to see if they are running on a virtual machine. It's very unpleasant to see alert messages such as "Sorry, this application cannot run under a Virtual Machine." and have your software stopped! There is a lot of legal reasons to override such tests. Moreover such limitations are (most of the time) not written in User License Agreement. So... how to hide a program that is running on a virtual machine? I'm using a Virtual Private Server (VPS) with Hyper-V... I'm administrator of the Operating System (Windows 2003) installed on this VPS, not administrator of Hyper-V.

  • Is wrapping a third party code the only solution to unit test its consumers? [closed]

    - by Songo
    I'm doing unit testing and in one of my classes I need to send a mail from one of the methods, so using constructor injection I inject an instance of Zend_Mail class which is in Zend framework. Now some people argue that if a library is stable enough and won't change often then there is no need to wrap it. So assuming that Zend_Mail is stable and won't change and it fits my needs entirely, then I won't need a wrapper for it. Now take a look at my class Logger that depends on Zend_Mail: class Logger{ private $mailer; function __construct(Zend_Mail $mail){ $this->mail=$mail; } function toBeTestedFunction(){ //Some code $this->mail->setTo('some value'); $this->mail->setSubject('some value'); $this->mail->setBody('some value'); $this->mail->send(); //Some } } However, Unit testing demands that I test one component at a time, so I need to mock the Zend_Mail class. In addition I'm violating the Dependency Inversion principle as my Logger class now depends on concretion not abstraction. Now is wrapping Zend_Mail the only solution or is there a better approach to this problem? The code is in PHP, but answers doesn't have to be. This is more of a design issue than a language specific feature

  • github team workflow - to fork or not?

    - by aporat
    We're a small team of web developers currently using subversion but soon we're making a switch to github. I'm looking at different types of github workflows, and we're not sure if the whole forking concept in github for each developer is such a good idea for us. If we use forks, I understand each developer will have his own private remote & local repositories. I'm worried it will make pushing changesets hard and too complex. Also, my biggest concern is that it will force each developer to have 2 remotes: origin (which is the remote fork) and an upstream (which is used to "sync" changes from the main repository). Not sure if it's such a easy way to do things. This is similar to the workflow explained here: https://github.com/usm-data-analysis/usm-data-analysis.github.com/wiki/Git-workflow If we don't use forks, we can probably get by fine by using a central repo creating a branch for each task we're working on, and merge them into the development branch on the same repository. It means we won't be able to restrict merging of branches and might be a little messy to have many branches on the central repository. Any suggestions from teams who tried both workflow?

  • Client-side certificates

    - by walshms
    My company purchased a wildcard certificate from a vendor. This certificate was successfully configured with Apache 2.2 to secure a subdomain. Everything on the SSL side works. Now I'm required to generate x509 client-side certificates to issue for this subdomain. I'm following along this page: (http://www.vanemery.com/Linux/Apache/apache-SSL.html), starting with "Creating Client Certificates for Authentication". I've generated the p12 files and successfully imported them into Firefox. When I browse to the site now, I get an error in FireFox that says "The connection to the server was reset while the page was loading." I think my problem is coming from not signing the client-side correctly. When I sign the client-side certificate, I'm using the PEM file (RapidSSL_CA_bundle.pem) from RapidSSL (who we bought the certificate from) for the -CA argument. For the -CAkey argument, I'm using the private key of the server. Is this correct?

  • Replace Certificate using Plesk 11

    - by Lambda Dusk
    I am not an admin, but a programmer. But how it is, if you're the only guy who knows about computers, everyone shoves those tasks to you. A certificate of a domain recently expired. The domains are managed using Plesk 11, on a Linux system, Apache2.2. I was given a new certificate from the host, and it is one single .pem file. However, Plesk asks me for a .crt file, a private key and some CA file. I have neither, only this single .pem file the host claims to be the certificate. Since I myself never did anything with SSL certificates, I would really appreciate if anyone can tell me what to do with this file and how to properly add a new one so the old one can be removed.
