  • Render Ruby object to interactive html

    - by AvImd
    I am developing a tool that discovers network services enabled on host and writes short summary on them like this: init,1 +-- login,1560 -- +-- bash,1629 +-- nc,12137 -lup 50505 { :net = [ [0] "*:50505 IPv4 UDP " ], :fds = [ [0] "/root (cwd)", [1] "/", [2] "/bin/nc.traditional", [3] "/xochikit/ld_poison.so (stat: No such file or directory)", [4] "/dev/tty2", [5] "*:50505" ] } It proved to be very nice formatted and useful for quick discovery thanks to colors provided by the awesome_print gem. However, its output is just a text. One issue is that if I want to share it, I lose colors. I'd also like to fold and unfold parts of objects, quickly jump to specific processes and what not? Adding comments, for example. Thus I want something web-based. What is the best approach to implement features like these? I haven't worked with web interfaces before and I don't have much experience with Ruby.

  • Refactoring this code that produces a reverse-lookup hash from another hash

    - by Frank Joseph Mattia
    This code is based on the idea of a Form Object http://blog.codeclimate.com/blog/2012/10/17/7-ways-to-decompose-fat-activerecord-models/ (see #3 if unfamiliar with the concept). My actual code in question may be found here: https://gist.github.com/frankjmattia/82a9945f30bde29eba88 The code takes a hash of objects/attributes and creates a reverse lookup hash to keep track of their delegations to do this. delegate :first_name, :email, to: :user, prefix: true But I am manually creating the delegations from a hash like this: DELEGATIONS = { user: [ :first_name, :email ] } At runtime when I want to look up the translated attribute names for the objects, all I have to go on are the delegated/prefixed (have to use a prefix to avoid naming collisions) attribute names like :user_first_name which aren't in sync with the rails i18n way of doing it: en: activerecord: attributes: user: email: 'Email Address' The code I have take the above delegations hash and turns it into a lookup table so when I override human_attribute_name I can get back the original attribute name and its class. Then I send #human_attribute_name to the original class with the original attribute name as its argument. The code I've come up with works but it is ugly to say the least. I've never really used #inject so this was a crash course for me and am quite unsure if this code effective way of solving my problem. Could someone recommend a simpler solution that does not require a reverse lookup table or does that seem like the right way to go? Thanks, - FJM

  • Teacher demands excessive/unjustified use of Design Patterns

    - by SoboLAN
    I study computer science and I have a class called "Programming Techniques". Its purpose is to teach (us) good object oriented design principles. During the semester we have homeworks, programs that we must write to demonstrate what we've learned. The lab assistant demands for each of these homeworks that specific design patterns should be used. For example, the current homework is an application used for processing customer orders. We are demanded to use either "Factory Method" or "Abstract Factory" design patterns for this. It gets even worse: at the end of the semester we must write a program (something more complex) that must use at least one creational pattern, at least one structural pattern and at least one behavioural pattern. Is it normal to demand this ? I mean, forcing us to design our programs in such a way that a specific design pattern makes sense is just beyond what I consider ok. If I'm a car mechanic and have a huge tool box, then I will use a certain tool from that box if and when the situation demands it. Not more, not less. If my design of the application doesn't demand at all the use of "Abstract Factory" (for example), then why should I implement it ? I'm not sure yet if the senior lecturer agrees with what the lab assistant is demanding, but I want to talk to him about it and I need solid arguments to do so. How should I approach this problem with him ? PS: I'm sure there must be a better way to teach us these things. Maybe making us each week read about 3 design patterns and the next week giving us a test with small but specific programming or architectural situations/problems. The goal in that test would be to identify what design patterns would make sense and how they could be implemented. This way, he can see if we understand them. EDIT: These homeworks are not just 100-line programs, they have quite a lot of requirements and are fairly complicated. This is the reason we have about 2 - 3 weeks of deadline for each of them. I agree that practicing this is the best way to learn. But shouldn't smaller programs/applications be used for this ? Something just for demonstrating purposes. Not big programs with lots of requirements/classes/etc.

  • Equivalent of #map in ruby in golang

    - by Oct
    I'm playing with Go and run into something I'm unable to find in Google, although there is certainly something that exists: I'm using the following struct: type Syntax struct { name string extensions *regexp.Regexp } type Scanner struct { classifier * bayesian.Classifier save_file string name_to_syntax map[string] *Syntax extensions_to_syntax map[*regexp.Regexp] *Syntax } I'd like to perform the following using Go and I'm quoting ruby because it's how I'd do that using ruby: test_regexpes = my_scanner.extensions_to_syntax.keys My goal is to get an array of *regexp.Regexp . Any idea on how to do that in a simple way ? Thank you !

  • Weaknesses of 3-Strike Security

    - by prelic
    I've been reading some literature on security, specifically password security/encryption, and there's been one thing that I've been wondering: is the 3-strike rule a perfect solution to password security? That is, if the number of password attempts is limited to some small number, after which all authentication requests will not be honored, will that not protect users from intrusion? I realize gaining access or control over something doesn't always mean going through the authentication system, but doesn't this feature make dictionary/brute-force attacks obsolete? Is there something I'm missing?

  • Detecting controls of a winform

    - by Ayush Saxena
    I have a circular area cursor which is a circular winform(translucent) hooked to a cursor. On click, I want to get hold of the controls in the region of the parent winform just below the area of the cursor/form. These controls have to be arranged in circular layout on a different form. I am working on C#.NET. Please tell how to access the controls of a winform and change their positions in context with my application described above. Like what classes, procedure , resources i need. I am a newbie but desperate to complete this task.thanks in advance.

  • Design for a plugin based application

    - by Varun Naik
    I am working on application, details of which I cannot discuss here. We have core framework and the rest is designed as plug in. In the core framework we have a domain object. This domain object is updated by the plugins. I have defined an interface in which I have function as DomainObject doProcessing(DomainObject object) My intention here is I pass the domain object, the plug in will update it and return it. This updated object is then passed again to different plugin to be updated. I am not sure if this is a good approach. I don't like passing the DomainObject to plugin. Is there a better way I can achieve this? Should I just request data from plugin and update the domain object myself?

  • How relevant is UTF-7 when it comes to parsing emails?

    - by J. Pablo Fernández
    I recently implemented incoming emails for an application and boy, did I open the gates of hell? Since then every other day an email arrives that makes the app fail in a different way. One of those things is emails encoded as UTF-7. Most emails come as ASCII, some of the Latin encodings, or thankfully, UTF-8. Hotmail error messages (like email address doesn't exist or quota exceeded) seem to come as UTF-7. Unfortunately, UTF-7 is not an encoding Ruby understands: > "hello world".encode("utf-8", "utf-7") Encoding::ConverterNotFoundError: code converter not found (UTF-7 to UTF-8) > Encoding::UTF_7 => #<Encoding:UTF-7 (dummy)> My application doesn't crash, it actually handles the email quite well, but it does send me a notification about the potential error. I spent some time googling and I can't find anyone that implemented the conversion, at least not as a Ruby 1.9.3 Encoding::Converter. So, my question is, since I never got an email with actual content, from an actual person, in UTF-7, how relevant is that encoding? can I safely ignore it?

  • How can we distribute a client app to other non-US businesses?

    - by Simon
    I'm working on an app which acts as a client for our web service. We sell this service to businesses, and we want to distribute the app to their employees for free. The app will be customised for each client. If we were in the US, my understanding is that we'd ask them to enrol in the volume purchasing program, and submit a version of our app for each business, for enterprise distribution at the free price point However, the businesses aren't all in the US, so they can't enrol in the VPP. They have thousands of employees, so promo codes won't be sufficient. What are our alternatives?

  • How does the ? make a quantifier lazy in regex

    - by Uriel Katz
    I've been looking into regex lately and figured that the ? operator makes the *,+, or ? lazy. My question is how does it do that? Is it that *? for example is a special operator, or does the ? have an effect on the *? In other words, does regex recognize *? as one operator in itself, or does regex recognize *? as the two separate operators * and ?? If it is the case that *? is being recognized as two separate operators, how does the ? affect the * to make it lazy. If ? means that the * is optional, shouldn't this mean that the * doesn't have to exists at all. If so, then in a statement .*? wouldn't regex just match separate letters and the whole string instead of the shorter string? Please explain, I'm desperate to understand.

  • using cin and cout in textmate [migrated]

    - by That Guy
    I am usually a Java programmer, and have used textmate for that almost exclusively, but lately I started using C++ with it. but when i use even the most basic programs and incorporate the cin keyword, and run the program, I dont get an oppurtunity to put in anything during runtime and sometimes it inserts random values by itself! for example, if i ran this in textmate: #include <iostream> int stonetolb(int); int main() { using namespace std; int stone; cout << "enter the weight in stone"; cin >> stone; int pounds = stonetolb(stone); cout << stone << "stone = "; cout << pounds <<" pounds."; return 0; } int stonetolb(int sts) { return 14 * sts; } I would come out with the output: enter the weight in stone32767stone = 458738 pounds. Why is this happening, and how do I stop it?

  • Patterns to refactor common code in multi-platform software

    - by L. De Leo
    I have a Django application and a PyQt application that share a lot of code. A big chunk of the PyQt application are copied verbatim from the Django application's views. As this is a game, I have already an engine.py module that I'm sharing among the two applications, but I was wondering how to restructure the middle layer (what in Django corresponds to the largest part of the views minus the return HttpResponse part) into its own component. In the web application the components are those of a classic Django application (with the only exception that I don't make any use of models): the game engine the url dispatcher the template the views My PyQt application is divided into: the game engine the UI definition where I declare the UI components and react to the events (basically this takes the place of the template and the url dispatcher in the Django app) the controller where I instantiate the window object and reproduce the methods that map the views in the Django app

  • Theoretically bug-free programs

    - by user2443423
    I have read lot of articles which state that code can't be bug-free, and they are talking about these theorems: Halting problem Gödel's incompleteness theorem Rice's theorem Actually Rice's theorem looks like an implication of the halting problem and the halting problem is in close relationship with Gödel's incompleteness theorem. Does this imply that every program will have at least one unintended behavior? Or does it mean that it's not possible to write code to verify it? What about recursive checking? Let's assume that I have two programs. Both of them have bugs, but they don't share the same bug. What will happen if I run them concurrently? And of course most of discussions talked about Turing machines. What about linear-bounded automation (real computers)?

  • Security in a private web service

    - by Oni
    I am developing a web site and a web service for a small on-line game. Technically, I'll be using Express (node.js) and MongoDB+Redis for the databases. This the structure I came up with: One Express server that will server as the Web Service. This will connect to the databases. One Express server that will provide the web site. It will connect to the Web Service to retrieve and push the information. iOS and Android application will be able to interact with the WebService. Taking into account: It is a small game. The information transferred is not critical. There will NOT be third party applications. At least for the moment. My concern is about which level of security I should use in each of the scenarios: Security of the user playing through web browser Security of the applications and the Web Server connecting to the WS. I have take a look at the different options and: OAuth and/or Https is too much for this scenario, isn't it? Will be a good option to hash the user and password with MD5(or similar) and some salt? I would like to get some directions and investigate by my own rather than getting a response like "you should you use this node.js module..." Thanks in advance,

    I'm currently looking to move to using an IDE for web development. The options I'm considering are: Aptana Studio Coda Expresso Please base your answers on the following criteria, in descending order of importance: Supports HTML, CSS, JavaScript Powerful (having good code completion, good debugger, great syntax highlighting etc) Fast and light Supports HTML5, CSS3, and major JavaScript frameworks (JQuery or YUI) Great design (both usability and aesthetics) Supports PHP, Ruby, and Python Has Git integrated I've updated the question to be more objective. I'm mainly looking for an answer that addresses how well each of the IDEs addresses my criteria.

  • Why did Alan Kay say, "The Internet was so well done, but the web was by amateurs"?

    - by kalaracey
    OK, so I paraphrased. The full quote: The Internet was done so well that most people think of it as a natural resource like the Pacific Ocean, rather than something that was man-made. When was the last time a technology with a scale like that was so error-free? The Web, in comparison, is a joke. The Web was done by amateurs. -- Alan Kay. I am trying to understand the history of the Internet and the web, and this statement is hard to understand. I have read elsewhere that the Internet is now used for very different things than it was designed for, and so perhaps that factors in. What makes the Internet so well done, and what makes the web so amateurish? (Of course, Alan Kay is fallible, and no one here is Alan Kay, so we can't know precisely why he said that, but what are some possible explanations?) *See also the original interview*.

  • Best way for a technical manager to stay up to date on technology

    - by JoelFan
    My manager asked for a list of technical blogs he should follow to stay current on technology. His problem is he keeps hearing terms that he hasn't heard of (i.e. NoSql, sharding, agure, sevice bus, etc.) and he would prefer to at least have a fighting chance of knowing something about them without having to be reactive and looking them up. Also I think he wants to have a big picture of all the emerging technologies and where they fit in together instead of just learning about each thing in isolation. He asked about blogs but I'm thinking print magazines may also help. What should I answer him?

  • Which Java web framework do you recommend for intranet webapp (not content website)?

    - by pregzt
    I'm about to start development of small purpose build intranet web application for small software vendor. It will be administration console of the server managing licenses for off-the-shelf software installed by users. There will be a few users who need to be able to sign in, issue a batch of license codes, revoke some, renew outdated, resolve issues, etc. Bear in mind that my customer requires Java for this solution. I'm seasoned Java programmer and before I used different frameworks to implement webapps, mainly Apache Struts in the past and Spring MVC recently. I was wondering what else could you recommend for such specific intranet webapp. I looked at using Google Web Toolkit (possibly with SmartGWT) Ext JS for fancy widgets in UI and REST back-end in SpringMVC SpringMVC with JQueryUI Could you please think of any piece of recommendation with regard to the choice I'm going to made?

  • Is C and Python enough?

    - by gruszczy
    I am very proficient in Python (including Django), which I use for most tasks. I am also quite confident with C; I am maintaining small file system in userspace written in C. Yet when I am browsing job offers I see everywhere Java/C# and sometimes C++. I have coded profesionally in C++ for half a year in a gaming company, but I don't consider myself a pro. Also I simply despise Java and C#, which I would prefer not to touch ever. But it seems to me, that I am at very unfavorable position, when it comes to career. I am browsing careers.stackoverflow.com and I don't see and pure python or C offers. I would like to find a new job abroad in about 6 months. If I find some python offer, it means doing web development (not my favorite job). Does it mean, that I have to quickly start improving my C++ skills, if I wish to find a satisfying job? What would you suggest me? EDIT Learning new technologies is not an issue. Company I am working in is an integrator. Basically every new project requires learning new technologies, sometimes custom made. During last two years I was writing SQLs by hand, using LDAP, writing GUI in Qt, working on large scale DBMS prototype, making our internal help desk system use gsm modem or writing own report system. In previous job I had to learn from basics everything what I could about games development, because I knew nothing and chose this job only because of the challene it posed. I am all about embracing new technologies. I have used Java in the past and simply didn't like it. It's dull and boring. Doesn't let me do anything cool. I have recently seen some C# in action and seems similar. I don't like it. It's like German. I don't like speaking German.

  • How can I boost my C# learning curve?

    - by MSU
    I have been learning programming, mostly C# and .net stuff. And I have target to become a fulltime .NET developer. But I am feeling that learning Graph is very slow, I have been learning C# programming, doing some coding everyday, but how I can learn very fast and increase my skills rapidly? I know there should be a balance of coding and reading, as without reading I can't code and without coding I can't increase my skills. SO, I am requesting here suggesting from experts on how I bring more pace to my learning curve? I intend to give 4-6 hours daily for this and on weekends 10+ hours.

  • Questions to ask a 3rd party API provider

    - by Jarede
    I'm due to meet with a developer/sales person from a new 3rd party resource we're about to start using. The main topic I'll be interested in, is their API as I will be the developer making use of it and explaining it to the rest of the team. What questions would you recommend asking? Things I'm already thinking about are: What happens and how will I be notified when they depreciate a method? Is there ever any downtime? Who will I deal with first when I have API issues?

  • Test a simple multi-player (upto four players) Android game in single developer machine

    - by Kush
    I'm working on a multi-player Android game (very simple it is that it doesn't have any game-engine used). The game is based on Java Socket. Four devices will connect the game server and a new thread will manage their session. The game server will server many such sessions (having 4 players each). What I'm worried about is the testing of this game. I know it is possible to run multiple android emulators, but my development laptop is very limited in capabilities (3 GB RAM, 2 Ghz Intel Core2Duo and on-board Graphics). And I'm already using Ubuntu to develop the game so that I have more user memory available than I'd have with Windows. Hence, the laptop will burn-to-death on running 4 emulator instances. I don't have access to any android device, neither I have another machine with higher configuration. And I still have to develop and test this game. P.S. : I'm a CS student, and currently don't work anywhere, and this game is college project, so if there are any paid solutions, I cannot afford it. What can I do to test the app seamlessly? ability to test even only 4 clients (i.e. only 1 session) would suffice, its alright if I can't simulate real environment with some 10-20 active game sessions (having 4 players each).

  • How to make a license apply to a whole library?

    - by Yannbane
    I'm creating a standard library for a programming language, and I'd like to license each and every single class or function in there under the MIT license, so they're completely FOSS. All of the files reside in a single directory. Would it be enough to put a LICENSE.txt file in the same directory, containing the MIT license? Do I need to say that the following license applies to all features of the library, or is the library itself considered to be a program?

  • Is there a constant for "end of time"?

    - by Nick Rosencrantz
    For some systems, the time value 9999-12-31 is used as the "end of time" as the end of the time that the computer can calculate. But what if it changes? Wouldn't it be better to define this time as a builtin variable? In C and other programming languages there usually is a variable such as MAX_INT or similar to get the largest value an integer could have. Why is there not a similar function for MAX_TIME i.e. set the variable to the "end of time" which for many systems usually is 9999-12-31. To avoid the problem of hardcoding to a wrong year (9999) could these systems introduce a variable for the "end of time"?

  • Design pattern for isomorphic trees

    - by Peregring-lk
    I want to create a data structure to work with isomorphic tree. I don't search for a "algorithms" or methods to check if two or more trees are isomorphic each other. Just to create various trees with the same structure. Example: 2 - - - - - - - 'a' - - - - - - - 3.5 / \ / \ / \ 3 3 'f' 'y' 1.0 3.1 / \ / \ / \ 4 7 'e' 'f' 2.3 7.7 The first "layer" or tree is the "natural tree" (a tree with natural numbers), the second layer is the "character tree" and the third one is the "float tree". The data structure has a method or iterator to traverse the tree and to make diferent operations with its values. These operations could change the value of nodes, but never its structure (first I create the structure and then I configure the tree with its diferent layers). In case of that I add a new node, this would be applied to each layer. Which known design pattern fits with this description or is related with it?
