  • Configuring Network without Default Gateway

    - by Homayoon
    I'm trying to connect my desktop and laptop using an ethernet connection. I usually configure network from the command line but this time I decided to give Network Manager a try, so I went to Network Connections, and selected manual IP configuration. At first I left the default gateway field blank, since I don't need a default gateway. Turned out network manager doesn't let me save the connection unless I enter that field, but entering a phony gateway messes up with my Internet connection. Anyway to do this setup?

  • How to set up Google Chrome as default browser in Xubuntu

    - by mpm
    I use Xubuntu 12.04. I uninstalled Firefox and now use Google Chrome version 19.xxx. To solve this problem, I tried: galternatives the "default apps" under settings and sudo update-alternatives --config x-www-browser Neither of these worked. Does anybody have an alternative solution for this? -- Solution: I used the "sudo gedit /usr/share/applications/defaults.list" tip from ??? and searched for firefox in the whole document! Everytime I found "firefox" I replaced it with "google-chrome.desktop". I also used the "default apps" menu to change it to google-chrome. And now it works.. I hope it helps some other ;-)

  • Default groups for user in Ubuntu 12.10?

    - by Sukminder
    Installed HP Linux Imaging and Printing by using install script and something crashed. Now I'm only member of my own group and lp. Which are the default groups for users in Ubuntu 12.10? Same as this? And, out of curiosity, is there some place where this information is logged? As i.e. some log file showing which groups my user was on previous boot? And/or is this information ,(which groups are default), documented somewhere? OK Found answer. Adding when I'm able (haven't got enough points and have to wait hours to answer myself).

  • Setting Default Ubuntu eth port

    - by No1_Melman
    Background: I have a desktop computer running Ubuntu 12.04. I have installed DRBL to handle DHCP server and Clonezilla Server. I have a network card in my desktop with 2 ports in it. These 2 ports are bonded together and are used by DRBL. There is a 3rd port integrated in the motherboard. I want to use this 3rd port for internet. DRBL knows that this is set for internet. Ubuntu Network-Manager has stopped recognising the connections (device not managed). It use to say that eth1 was default (first port in the network card) I want eth0 to be default as that is the Internet port. Question: How do I make network-manager see eth0 as the defualt port?

  • .xprofile isn't enough

    I've been trying to find a solution on how to change the screen resolution on the login screen and other users. .xprofile will only affect my account. I've been searching for a few months but I got nothing. Please help. It would be easier if the "Default Resolution" was still there in the monitors settings. Plus, I'm afraid of editing the xorg.conf. Last time was ugly...

  • Is Perl still a useful, viable language?

    - by Bob
    I know it may have been asked before, but here goes nothing... Is Perl still something that would be considered useful? If someone was a new programmer (either completely new to programming or just a few month/years of experience) would Perl be something to be considered worthwhile to learn? Is Perl still used with frequency? Is it still popular? Or is Perl dying out compared to languages like Python, Ruby, PHP, ASP, .NET, etc.? Basically it boils down to this: Is it still used/is it still used frequently? If yes, is it dying? If no, will it make a come back? Is it something that would be worth learning? How does it compare in demand to languages like Python in both popularity and usability/viability? Could languages like Python or Ruby be considered replacements for Perl? Also, will newer versions of Perl really bring a large improvement to the Perl community, and perhaps bring Perl back to centerstage compared to other languages? EDIT: Okay, I suppose here's a better, reworded question: Is Perl still growing, or is it "dying"? Is it still a language worth learning and using? What projects does it really "shine" in compared to other languages? What makes Perl a language to choose? Essentially: is Perl growing obsolete compared to other languages, and if so, do you expect that to change, or to continue? And thank you to everyone who has answered so far, the discussion has been really interesting!

  • So, "Are Design Patterns Missing Language Features"?

    - by Eduard Florinescu
    I saw the answer to this question: How does thinking on design patterns and OOP practices change in dynamic and weakly-typed languages? There it is a link to an article with an outspoken title: Are Design Patterns Missing Language Features. But where you can get snippets that seem very objective and factual and that can be verified from experience like: PaulGraham said "Peter Norvig found that 16 of the 23 patterns in Design Patterns were 'invisible or simpler' in Lisp." and a thing that confirms what I recently seen with people trying to simulate classes in javascript: Of course, nobody ever speaks of the "function" pattern, or the "class" pattern, or numerous other things that we take for granted because most languages provide them as built-in features. OTOH, programmers in a purely PrototypeOrientedLanguage? might well find it convenient to simulate classes with prototypes... I am taking into consideration also that design patterns are a communcation tool and because even with my limited experience participating in building applications I can see as an anti-pattern(ineffective and/or counterproductive) for example forcing a small PHP team to learn GoF patterns for small to medium intranet app, I am aware that scale, scope and purpose can determine what is effective and/or productive. I saw small commercial applications that mixed functional with OOP and still be maintainable, and I don't know if many would need for example in python to write a singleton but for me a simple module does the thing. patterns So are there studies or hands on experience shared that takes into consideration, all this, scale and scope of project, dynamics and size of the team, languages and technologies, so that you don't feel that a (difficult for some)design pattern is there just because there isn't a simpler way to do it or that it cannot be done by a language feature?

  • Syntax Highlighting for Gherkin (Cucumber Language)

    - by Liam McLennan
    SyntaxHighlighter is the de facto standard for syntax highlighting on the web. I am currently working on a tool for publishing BDD specifications on the web and I want syntax highlighting. Unfortunately, SyntaxHighlighter does not support Gherkin, the language Cucumber and SpecFlow use to define BDD specifications. Writing new language parsers for SyntaxHighlighter is very easy, so I implemented one for Gherkin. Here is what a syntax highlighted Gherkin file looks like: # A comment here Feature: Some terse yet descriptive text of what is desired In order to realize a named business value As a explicit system actor I want to gain some beneficial outcome which furthers the goal @secretlabel Scenario: Some determinable business situation Given some precondition And some other precondition When some action by the actor And some other action And yet another action Then some testable outcome is achieved And something else we can check happens too Like all SyntaxHighlighter brushes to use this one you need to install the brush (shBrushGherkin.js). I have also used a custom theme to get it just the way I wanted it (shThemeGherkin.css). If you would like to use my Gherkin brush you may download the code and example page.

  • Types of quotes for an HTML templating language

    - by Ralph
    I'm developing a templating language, and now I'm trying to decide on what I should do with quotes. I'm thinking about having 3 different types of quotes which are all handled differently: backtick ` double quote " single quote ' expand variables ? yes no escape sequences no yes ? escape html no yes yes Backticks Backticks are meant to be used for outputting JavaScript or unescaped HTML. It's often handy to be able to pass variables into JS, but it could also cause issues with things being treated as variables that shouldn't. My variables are PHP-style ($var) so I'm thinking that might mess with jQuery pretty bad... but if I disable variable expansion w/ backticks then, I'm not sure how would insert a variable into a JS code block? Single Quotes Not sure if escape sequences like \n should be treated as literals or converted. I find it pretty rare that I want to disable escape sequences, but if you do, you could use backticks. So I'm leaning towards "yes" for this one, but that would be contrary to how PHP does it. Double Quotes Pretty certain I want everything enabled for this one. Modifiers I'm also thinking about adding modifiers like @ or r in front of the string that would change some of these options to enable a few more combinations. I would need 9 different quotes or 3 quotes and 2 modifiers to get every combination wouldn't I? My language also supports "filters" which can be applied against any "term" (number, variable, string) so you could always write something like "blah blah $var blah"|expandvars Or "my string"|escapehtml Thoughts? What would you prefer? What would be least confusing/most intuitive?

  • Multi language site - use of canonical link and link rel="alternate"

    - by julia
    I keep reading everywhere that if you have a multilanguage site, where the same page appears in, say, French and English, then this is considered as duplicate content by google. It is written that using canonical link is the solution, but I do not understand how to use it in this case. Should I: Choose either French URL or English URL to be the canonical (main) one, and where I will place the canonical link? If so, how do I decide which of the two URLs must be canonical? both languages are important to me and I want the content under both languages to be indexed by google and served to the user, depending on the language in which he searches. OR should I place a canonical link on both French and English URLs? If so, then I do not understand the meaning of using the canonical link? In this case would both URLs be indexed, are both of them considered as "important" by google and not duplicates? Also I read that link rel="alternate" can be used to indicate to google that, for example the French URL is the French-language equivalent of the English page. This makes sense and I understand how to use such links, but how are they combined with canonical links? Should I define both the canonical URL AND specify rel="alternate" in both URLs? Could someone help me to clarify this, cause I'm stuck with this and can't seem to find a good-enough explanation in different sources.

  • Should I pick up a functional programming language?

    - by Statement
    I have recently been more concerned about the way I write my code. After reading a few books on design patterns (and overzealous implementation of them, I'm sure) I have shifted my thinking greatly toward encapsulating that which change. I tend to notice that I write less interfaces and more method-oriented code, where I love to spruce life into old classes with predicates, actions and other delegate tasks. I tend to think that it's often the actions that change, so I encapsulate those. I even often, although not always, break down interfaces to a single method, and then I prefer to use a delegate for the task instead of forcing client code to create a new class. So I guess it then hit me. Should I be doing functional programming instead? Edit: I may have a misconception about functional programming. Currently my language of choice is C#, and I come from a C++ background. I work as a game developer but I am currently unemployed. I have a great passion for architecture. My virtues are clean, flexible, reusable and maintainable code. I don't know if I have been poisoned by these ways or if it is for the better. Am I having a refactoring fever or should I move on? I understand this might be a question about "use the right tool for the job", but I'd like to hear your thoughts. Should I pick up a functional language? One of my fear factors is to leave the comfort of Visual Studio.

  • The Oldest Big Data Problem: Parsing Human Language

    - by dan.mcclary
    There's a new whitepaper up on Oracle Technology Network which details the use of Digital Reasoning Systems' Synthesys software on Oracle Big Data Appliance.  Digital Reasoning's approach is inherently "big data friendly," as it leverages multiple components of the Hadoop ecosystem.  Moreover, the paper addresses the oldest big data problem of them all: extracting knowledge from human text.   You can find the paper here.   From the Executive Summary: There is a wealth of information to be extracted from natural language, but that extraction is challenging. The volume of human language we generate constitutes a natural Big Data problem, while its complexity and nuance requires a particular expertise to model and mine. In this paper we illustrate the impressive combination of Oracle Big Data Appliance and Digital Reasoning Synthesys software. The combination of Synthesys and Big Data Appliance makes it possible to analyze tens of millions of documents in a matter of hours. Moreover, this powerful combination achieves four times greater throughput than conducting the equivalent analysis on a much larger cloud-deployed Hadoop cluster.

  • How to popularize Nemerle (or another programming language)?

    - by keykeeper
    Any .NET developer who is interested in different programming languages knows that F# is the most popular functional language for the .NET platform nowadays. The only fact describing the popularity of F# is the great support of Microsoft. But we are not limited with F# at all. There are some other functional languages on the .NET platform. I'm very disappointed with the fact that Nemerle isn't well-known. It's an awesome language which supports three paradigms: object-oriented, functional and meta- programming. I won't try to explain why I like it so much. The problem is that I can't use it at work. I think that only really brave companies can rely on Nemerle. It's almost unknown, that's why it's hard to find new developers for the project. Noone wants to make a first step with Nemerle if it can influence the budget what is reasonable. So, here is a question: what can I do to make Nemerle more popular? Here are my first ideas: implement open-source projects using Nemerle; make presentations on different conferences; write articles.

  • Mutating Programming Language?

    - by MattiasK
    For fun I was thinking about how one could build a programming language that differs from OOP and came up with this concept. I don't have a strong foundation in computer science so it might be common place without me knowing it (more likely it's just a stupid idea :) I apologize in advance for this somewhat rambling question :) Anyways here goes: In normal OOP methods and classes are variant only upon parameters, meaning if two different classes/methods call the same method they get the same output. My, perhaps crazy idea, is that the calling method and class could be an "invisible" part of it's signature and the response could vary depending on who call's an method. Say that we have a Window object with a Break() method, now anyone (who has access) could call this method on Window with the same result. Now say that we have two different objects, Hammer and SledgeHammer. If Break need to produce different results based on these we'd pass them as parameters Break(IBluntObject bluntObject) With a mutating programming language (mpl) the operating objects on the method would be visible to the Break Method without begin explicitly defined and it could adopt itself based on them). So if SledgeHammer calls Window.Break() it would generate vastly different results than if Hammer did so. If OOP classes are black boxes then MPL are black boxes that knows who's (trying) to push it's buttons and can adapt accordingly. You could also have different permission sets on methods depending who's calling them rather than having absolute permissions like public and private. Does this have any advantage over OOP? Or perhaps I should say, would it add anything to it since you should be able to simply add this aspect to methods (just give access to a CallingMethod and CallingClass variable in context) I'm not sure, might be to hard to wrap one's head around, it would be kinda interesting to have classes that adopted themselves to who uses them though. Still it's an interesting concept, what do you think, is it viable?

  • Is there a language more general than Lisp?

    - by Jon Purdy
    I've been programming for a long time, and writing in Lisp (well, mostly Scheme) for a little less. My experience in these languages (and other functional languages) has informed my ability to write clean code even with less powerful tools. Lisp-family languages have lovely facilities for implementing every abstraction in common use: S-expressions generalise structure. Macros generalise syntax. Continuations generalise flow control. But I'm dissatisfied. Somehow, I want more. Is there a language that's more general? More powerful? As great as Lisp is, I find it hard to believe no one has come up with anything (dare I say) better. I'm well aware that ordinarily a question like this ought to be closed for its argumentative nature. But there seems to be a broad consensus that Lisp represents the theoretical pinnacle of programming language design. I simply refuse to accept that without some kind of proof. Which I guess amounts to questioning whether the lambda calculus is in fact the ideal abstraction of computation.

  • Browser language detection & content ranking for new language on the same site.

    - by Arnaud
    I've been reading a lot about it but it's still really hard to make up my mind. My understand is that if your website provide a link to the other language, this should not be an issue for google as long as your links are clear and clean, google will be able to make his way through it. The website was orginaly in french and I added the english version and I'm just worry that english speaker will just leave if the site is not in the correct language, for the home page I just wanted to get the value from the browser and redirect it to /fr/ or /en/ for the first page. (using php this will be very easy) Could you guys have a look at it and tell me what you think about it http://tinyurl.com/bpc5bn9 I don't want to get it wrong and lost my ranking with google. Also the website has good rank on the french side and the english has been online for 2 weeks and only get few visit a day, is that because all the back link refer to /fr/ and google is cleaver enough to decide that they are 2 differantes website and the back link will have to point to /en/ to increase the ranking value? Or will take few more weeks for the website to grow? Thanks for your hep

  • Scripting language for filling out web form

    - by ityler22
    I have a job as an intern at a technology company, I was given the unfortunate job of performing some data entry into our web management system. The information entered into the web form is stored in a MySQL DB. Upon receiving the data I realized I would have to submit this online form about 1000 different times all consisting of about 10 different text fields / check boxes per form. (So in other words, would be completely mind numbing and be a ridiculous waste of time and resources, or so I thought...) Having used databases a good bit prior to this, my immediate reaction was to just write a short MySQL script to bulk import all of the data, especially since it was already presented to me in an excel spreadsheet ready to go. Thought it may have been some sort of a test since it seemed too obvious. I wrote the script which consisted of about 10 lines of code but was then informed I couldn't be trusted with MySQL Admin privileges to run said script. So my next thought would be to write a script to just enter the information through the web form (Which will take ten times longer but it's what I have to) Being unfamiliar with scripting of this nature (seems like I would need something similar to a bot, but the good kind) I was unsure of how to proceed to do this. Is there a preferred language to use to enter the data i have into the web form I do have access to? I'm not particularly looking for this to be done for me by any means just a nice point in the right direction as far as what scripting language to use and how to pair that with the data I have that needs to be entered. Thanks for the help/ valuable input! EDIT: Is there a way to perform this using perl without having access to place any files on the server? Would I be able to run some Javascript loops to pull the data out of .csv or just a .txt format with line delimiters and insert it into the web form?
