  • Dealing with a gfortran error?

    - by user293253
    I usually do some pieces of code in Fortran and C for my job, but since some days ago I get the following error: $ gfortran D.f -o D.x gfortran: error trying to exec 'f951': execvp: No such file or directory (I have Ubuntu 14.04 on a I7, 8cores and 64b) I did try searching on the forums and several option but nothing seems to work ... Could somebody help ... ? I guess the problem started when I did something to install adobereader and/or skype.

  • Citrix SDK: Where to start? [closed]

    - by Bob Dole
    I'm needing to start hacking around the Citrix SDK and am trying to figure out where to start. I'm wanting to basically find a way to pass data from the client to the server and figure out how to open an application on the citrix client. I see there is a XenApp SDK, and Virtual Channel SDK but really don't know which one I need to start with. I have a Citrix development virtual server set up, but am unsure how to get started. Does someone know of a good site/tutorial on how to get started with the various Citrix API's quickly?

  • How can I really master a programming language?

    - by cprogcr
    I know that learning a language, you can simply buy a book, follow the examples, and whenever possible try the exercises. But what I'm really looking is how to master the language once you've learned it. Now I know that experience is one major factor, but what about learning the internals of the language, what is the underlying structure, etc. There are articles out there saying read this book, read that book, make this game and that game. But to me this doesn't mean to master a language. I want to be able to read other people's code and understand it, no matter how hard that is. To understand when to use a function and when another, etc etc. The list could go on and on but I believe I've made the point. :) And finally, take whatever language as an example if needed, though best would be if C was taken as an example.

  • Store image as logic file (in db by using binary format) or physical file (in the server)

    - by Michel Ayres
    In those study cases of image storage, An image that change only once in a while, if it changes at all (like an image for an article) The image case from above is not only one image but over 10, that link to the same article An image that have changes very often (like a banner image for a website) The image above is huge What is the best approach for each case? What is the "right/faster" way to do this task in each scenario ?

  • Complex string matching with fuzzywuzzy

    - by That1Guy
    I'm attempting to write a process that matches obscure strings to a single 'master string' for further processing. I have a lot of data that looks something like this: Basketball Basket Ball Football BasketBallR BBall BBall - r FootB ...and so on. These need to be mapped to a master record like so: Basketball = Basket Ball, BBall Basketball - R = BasketBallR, BBall - r I also have instances of data resembling this format: Football -r FootBall - r-g/H,Q,HH These situations need to be separated into different categories before being mapped. For example FootBall - r-g/H,Q,HH should be: Football - r Football - g Football - H Football - Q Football - HH At this point, it still needs to be mapped to a master record... I've tried several different combinations of fuzzywuzzy matching methods, Levenshtein Distance measurements, regex, etc. and can't seem to find a reliable method to logically associate different naming styles of a single item with a master name. I'm throwing my hands up in desperation. Are there any existing python resources than can help sort out my problem? Are there other options? Can anybody point out an obvious option that I might have overlooked? Basically, any suggestion, solution, resource or alternative method is greatly appreciated.

  • Is avoiding the private access specifier in PHP justified?

    - by Tifa
    I come from a Java background and I have been working with PHP for almost a year now. I have worked with WordPress, Zend and currently I'm using CakePHP. I was going through Cake's lib and I couldn't help notice that Cake goes a long way avoiding the "private" access specifier. Cake says Try to avoid private methods or variables, though, in favor of protected ones. The latter can be accessed or modified by subclasses, whereas private ones prevent extension or re-use. in this tutorial. Why does Cake overly shun the "private" access specifier while good OO design encourages its use i.e to apply the most restrictive visibility for a class member that is not intended to be part of its exported API? I'm willing to believe that "private" functions are difficult test, but is rest of the convention justified outside Cake? or perhaps it's just a Cake convention of OO design geared towards extensibility at the expense of being a stickler for stringent (or traditional?) OO design?

  • Is OpenStack suitable as a fault tolerant DB host?

    - by Jit B
    I am trying to design a fault tolerant DB cluster (schema does not matter) that would not require much maintenance. After looking at almost everything from MySQL to MongoDB to HBase I still find that no DB is easily scalable - Cassandra comes close but it has its own set of problems. So I was thinking what if I run something like MySQL or OrientDB on top of a large openstack VM. The VM would be fault tolerant by itself so I dont need to do it st DB level. Is it viable? Has it been done before? If not then what are the possible problems with this approach?

  • Trac/SVN to DVCS Migration

    - by quanticle
    The project I'm currently working on is using Trac, with SVN integration. It's worked great until now. Now, however, we've taken on some additional developers and we're running into issues with branching and merging. Because of this, I think a move to a distributed version control system is in order. The problem is that Trac is very closely integrated with the SVN repository. We have tight integration between the tickets and the revision numbers of code changes corresponding to those tickets. In addition we have a support wiki that has a lot of data that helps the tech. support team. Is there a way we can migrate to git or mercurial without losing the benefits of Trac? I've looked at the git plugin for Trac, and I'm unsure of how well it works. Has anyone here used it with a project that's been migrated from SVN? EDIT: I should note that the most important priority for us is maintaining the links between Trac tickets and the corresponding changesets in SVN. That's a tool that we use every day, and it provides an easy way to jump to code changes when reviewing tickets. Wiki migration would be nice to have, but if it's not possible, we can continue to run the old system whilst we write some kind of a one-off script to migrate the content.

  • I'm a premature optimizer

    - by Matthew Day
    I work in a small sized software/web development company. I have gotten into the habit of optimizing prematurely, I know it is evil and promotes bad code... But I have been working at this firm for a long while and I have deemed this as a necessary evil. It has never caused me an issue so far in the past, but it might if I get partners or a successor. The point of this long-winded speech is that, should I change my evil practices to 'save face' and to help out in the future?

  • What are the advantages of storing xml in a relational database?

    - by Chris
    I was poking around the AdventureWorks database today and I noticed that a number of tables (HumanResources.JobCandidate and Sales.Individual for example) have a column which is storing xml data. What I would to know is, what is the advantage of storing basically a database table row's worth of data in another table's column? Doesn't this make it difficult to query off of this information? Or is the assumption that the data won't need to be queried and just needs to be stored?

  • How to make a PHP function triggered automatically at a user defined time

    - by mithilatw
    I am developing an internal system for a company with PHP using Zend framework. I need one of its functions to execute on a time specified by user. My research on this matter found me several ways of doing this using CPanel Cron jobs and setting up scheduled tasks on the server. But in this scenario, I don't have a CPanel and I already use scheduled tasks. But my challenge is to provide an interface for the user to specify the time to trigger the function.

  • How to avoid being an API programmer only?

    - by anything
    I have almost six years of experience in java. I have developed many projects which used frameworks like Struts, Spring, Hibernate, JQuery , DWR, Ajax etc. I have used these technologies in almost all the projects I have worked on. Projects were very simple mostly with crud based apps. My everyday tasks involves creating few screens, writing queries, testing etc. After all these years I feel like I have turned into an API programmer who just uses these above mentioned frameworks which is not giving me any satisfaction of being a programmer. Is this normal or is it just me who is feeling like this?

  • How to get around the Circular Reference issue with JSON and Entity

    - by DanScan
    I have been experimenting with creating a website that leverages MVC with JSON for my presentation layer and Entity framework for data model/database. My Issue comes into play with serializing my Model objects into JSON. I am using the code first method to create my database. When doing the code first method a one to many relationship (parent/child) requires the child to have a reference back to the parent. (Example code my be a typo but you get the picture) class parent { public List<child> Children{get;set;} public int Id{get;set;} } class child { public int ParentId{get;set;} [ForeignKey("ParentId")] public parent MyParent{get;set;} public string name{get;set;} } When returning a "parent" object via a JsonResult a circular reference error is thrown because "child" has a property of class parent. I have tried the ScriptIgnore attribute but I lose the ability to look at the child objects. I will need to display information in a parent child view at some point. I have tried to make base classes for both parent and child that do not have a circular reference. Unfortunately when I attempt to send the baseParent and baseChild these are read by the JSON Parser as their derived classes (I am pretty sure this concept is escaping me). Base.baseParent basep = (Base.baseParent)parent; return Json(basep, JsonRequestBehavior.AllowGet); The one solution I have come up with is to create "View" Models. I create simple versions of the database models that do not include the reference to the parent class. These view models each have method to return the Database Version and a constructor that takes the database model as a parameter (viewmodel.name = databasemodel.name). This method seems forced although it works. NOTE:I am posting here because I think this is more discussion worthy. I could leverage a different design pattern to over come this issue or it could be as simple as using a different attribute on my model. In my searching I have not seen a good method to overcome this problem. My end goal would be to have a nice MVC application that heavily leverages JSON for communicating with the server and displaying data. While maintaining a consistant model across layers (or as best as I can come up with).

  • Logic or Algorithm to solve this problem [closed]

    - by jade
    I have two lists. List1 {a,b,c,d,e} and List2 {f,g,h,i,j} The relation between the two list is as follows a->g,a->h,h->c,h->d,d->i,d->j Now I have these two lists displayed. Based on the relation above on selecting element a from List1, List2 shows g,h. On selecting h from List2, in List1 c,d are shown in List1. On selecting d from List1 it shows i,j in List2. How to trace back to initial state by deselecting the elements in reverse order in which they have been selected?

  • What's the term describing this system for generating user interfaces?

    - by mjfgates
    So, there's this idea, which you already know: Define the layout of your UI by creating a tree of panels. The leaf nodes on the tree are what we used to call 'controls' way back in the day-- the things that the user interacts with, radio buttons and listboxes and such. The internal nodes are mostly concerned with layout; this kind of panel stacks its child panels vertically, that kind puts its children into a grid, etc. It's COMMON. Most of the UI-generating systems I've seen in the past twenty years are implementations of this, and the ones that aren't borrow from it. What's the word for this idea?

  • Trying to learn ASP.net

    - by sipl
    Hi There, I have a background in computers and had done programming some seven years ago. Switched to becoming a technical writer (oops!). And now think I should jump ship again, back to being a programmer. Of course the natural course of action where I can spend say two whole years learning to code, might not be available any more. I am keen on ASP.net as its the language that most products at my company are written in. I am sure this has been asked before, but here I go... where do I begin? Would really appreciate some practical advise. Thanks, SA

  • Scenario to illustrate how unit testing leads to better design

    - by Cocowalla
    For an internal training session, I'm trying to come up with a simple scenario that illustrates how unit testing leads to better design, by forcing you to think about things like coupling before you start coding. The idea is that I get the participants to code something first, without considering unit testing, then we do it again, but considering unit testing. Hopefully the code produced second time round should be more decoupled and maintainable. I'm struggling to come up with a scenario that can be coded quickly, yet can still demonstrate how unit testing can lead to better overall design.

  • Contractor - Mispaid again - Walked out

    - by MeshMan
    Hi all, I'm wondering whether or not I've done the right thing as a contractor. Basically I'm in to my 3rd month, and my current client messed up the payment in the first month, and I just found out that they are again late in paying me for my 2nd month. It wouldn't be so bad if I wasn't in a bit of a financial situation due to this being my first contract experience. But as a matter of principal, I walked out on them and will be telling them that I will not be going back in until they resolve the pay. Part of me feels as though this was not a very professional thing to do, but I also don't feel that it was very professional for them to mess my payments up, twice in a row. Did I make the right decision? I still want to work for these guys and enjoy the job, but I have a life to attend to that requires finances and I can't afford to keep getting messed up with pay like this. I attempted to phrase the question to be oriented around contractors behaviour around clients that mis-treat them, and as some of the answers that have been posted so far, it's a good discussion. The answers coming in are great around different subjective situations.

  • Why not commit unresolved changes?

    - by Explosion Pills
    In a traditional VCS, I can understand why you would not commit unresolved files because you could break the build. However, I don't understand why you shouldn't commit unresolved files in a DVCS (some of them will actually prevent you from committing the files). Instead, I think that your repository should be locked from pushing and pulling, but not committing. Being able to commit during the merging process has several advantages (as I see it): The actual merge changes are in history. If the merge was very large, you could make periodic commits. If you made a mistake, it would be much easier to roll back (without having to redo the entire merge). The files could remain flagged as unresolved until they were marked as resolved. This would prevent pushing/pulling. You could also potentially have a set of changesets act as the merge instead of just a single one. This would allow you to still use tools such as git rerere. So why is committing with unresolved files frowned upon/prevented? Is there any reason other than tradition?

  • Clustering Strings on the basis of Common Substrings

    - by pk188
    I have around 10000+ strings and have to identify and group all the strings which looks similar(I base the similarity on the number of common words between any two give strings). The more number of common words, more similar the strings would be. For instance: How to make another layer from an existing layer Unable to edit data on the network drive Existing layers in the desktop Assistance with network drive In this case, the strings 1 and 3 are similar with common words Existing, Layer and 2 and 4 are similar with common words Network Drive(eliminating stop word) The steps I'm following are: Iterate through the data set Do a row by row comparison Find the common words between the strings Form a cluster where number of common words is greater than or equal to 2(eliminating stop words) If number of common words<2, put the string in a new cluster. Assign the rows either to the existing clusters or form a new one depending upon the common words Continue until all the strings are processed I am implementing the project in C#, and have got till step 3. However, I'm not sure how to proceed with the clustering. I have researched a lot about string clustering but could not find any solution that fits my problem. Your inputs would be highly appreciated.
