• IBM lancera sa suite bureautique Cloud LotusLive Symphony pour contrer Google, Microsoft et Oracle

  IBM lancera sa suite bureautique Cloud LotusLive Symphony pour contrer Google, Microsoft et Oracle Jusqu'ici, IBM proposait plusieurs outils professionnels en mode hébergé (partage de fichiers, messagerie instantanée et vidéo-conférence, mails, etc.) avec LotusLive. Mais le numéro 2 mondial du logiciel ne proposait pas de suite bureautique. Un problème qui allait devenir stratégique puisque le numéro 1, Microsoft, a lancé l'été dernier ses Office Web Apps, et le numéro 3, Oracle, son Cloud Office en fin d'année. IBM a donc ann...

• To reorganize code, what to choose between library and service?

  - by essbeev

  I want to reorganize a large application with lot of code duplication into multiple components. Plus, some code is also duplicated over other applications. The common set of functionality that can be taken out of main application is clearly defined. Now, do I write a library or do I write a service for this functionality; so that all such applications continue to work and there is only one code-base (of common functionality) to maintain ?

• Lazy Processing of Streams

  - by Giorgio

  I have the following problem scenario: I have a text file and I have to read it and split it into lines. Some lines might need to be dropped (according to criteria that are not fixed). The lines that are not dropped must be parsed into some predefined records. Records that are not valid must be dropped. Duplicate records may exist and, in such a case, they are consecutive. If duplicate / multiple records exist, only one item should be kept. The remaining records should be grouped according to the value contained in one field; all records belonging to the same group appear one after another (e.g. AAAABBBBCCDEEEFF and so on). The records of each group should be numbered (1, 2, 3, 4, ...). For each group the numbering starts from 1. The records must then be saved somewhere / consumed in the same order as they were produced. I have to implement this in Java or C++. My first idea was to define functions / methods like: One method to get all the lines from the file. One method to filter out the unwanted lines. One method to parse the filtered lines into valid records. One method to remove duplicate records. One method to group records and number them. The problem is that the data I am going to read can be too big and might not fit into main memory: so I cannot just construct all these lists and apply my functions one after the other. On the other hand, I think I do not need to fit all the data in main memory at once because once a record has been consumed all its underlying data (basically the lines of text between the previous record and the current record, and the record itself) can be disposed of. With the little knowledge I have of Haskell I have immediately thought about some kind of lazy evaluation, in which instead of applying functions to lists that have been completely computed, I have different streams of data that are built on top of each other and, at each moment, only the needed portion of each stream is materialized in main memory. But I have to implement this in Java or C++. So my question is which design pattern or other technique can allow me to implement this lazy processing of streams in one of these languages.

• Website Remodel Redirects

  - by inKit

  We've recently built a site for a new client who has not inserted all the content that they had from their old site into their new one. Also a lot of content is dynamic with ID's not matching from the old site to the new one. We have added dynamic redirects for most of the patterns we could find in pages that were 404ing, but there are still a lot of pages that had content, or just jumbled urls that we cannot match up with content pages on the new site. Is it better to redirect these leftover pages to the homepage? Or leave them 404ing?

• "Testing Plan Lite" for web project

  - by Emmmmm

  How do you draft a quick & easy "Testing Plan Lite" for a medium-sized web project (70k lines, 2 developers)? I've seen many tutorials/articles on methods of testing, but all seem cumbersome. For us, the goal is to be able to be able to divide up and delegate testing instructions to our friends for different project segments, browsers, etc. What's the quick & easy way to write test plans for web apps? (the 20 of the 20/80 rule) Thanks!

• How should UI layer pass user input to BL layer?

  - by BornToCode

  I'm building an n-tier application, I have UI, BL, DAL & Entities (built from POCO) projects. (All projects have a reference to the Entities). My question is - how should I pass user input from the UI to the BL, as a bunch of strings passed to the BL method and the BL will build the object from the parameters, or should I build the objects inside the UI submit_function and send objects as parameters? EDIT: I wrote n-tier application, but what I actually meant was just layers.

• Pending and Approval process

  - by zen

  So let's say I have a DB table with 8 columns, one is a unique auto-incrementing used as ID. So I have a page that pulls in the info for each row based on query string ID. I want to give my users the ability to propose changes. Kinda like a wiki setup. So I was thinking I should just have another duplicate table or maybe database altogether (without the auto-incrementing column and maybe with a date edited column) that keeps all proposed changes in queue and then when I approve them, the script can move the row from the proposed DB to the real DB. Does this sound good or is there a better process for this?

• Is "convention over configuration" not violating basic programming principles?

  - by Geerten

  I was looking at the WPF MVVM framework Caliburn.Micro and read that a lot of standard things are based on naming conventions. For example, automatic binding of properties in the View to properties in the ViewModel. Although this seems to be convenient (removes some boilerplate code), my first instinct reaction is that it isn't completely obvious to a new programmer that will read this code. In other words, the functionality of the application is not completely explained by its own code, but also by the documentation of the framework. EDIT: So this approach is called convention over configuration. Since I could not find any questions concerning this, I altered my question: My question is: Is convention over configuration a correct way of simplifying things, or is it violating some programming principles (and if so, which ones)?

• What is the possible disadvantage of putting declarations in inner blocks, instead of at beginning of function?

  - by shan23

  At the place where I work, there are explicit guidelines for placement of declarations of variables. According to that, it is required to put them at the global level and / or at the beginning of functions, and not in inner blocks (such as a for loop). Since they've been specified by persons more experienced than I am, I'm sure that there must be a good reason for it, but I cannot figure out what that might be. It would be nice to know if there are any compile time / run time advantages at having them declared at a bigger scope.

• Entry level engineer question regarding memory management

  - by Ealianis

  It has been a few months since I started my position as an entry level software developer. Now that I am past some learning curves (e.g. the language, jargon, syntax of VB and C#) I'm starting to focus on more esoteric topics, as to write better software. A simple question I presented to a fellow coworker was responded with "I'm focusing on the wrong things." While I respect this coworker I do disagree that this is a "wrong thing" to focus upon. Here was the code (in VB) and followed by the question. Note: The Function GenerateAlert() returns an integer. Dim alertID as Integer = GenerateAlert() _errorDictionary.Add(argErrorID, NewErrorInfo(Now(), alertID)) vs... _errorDictionary.Add(argErrorID, New ErrorInfo(Now(), GenerateAlert())) I originally wrote the latter and rewrote it with the "Dim alertID" so that someone else might find it easier to read. But here was my concern and question: Should one write this with the Dim AlertID, it would in fact take up more memory; finite but more, and should this method be called many times could it lead to an issue? How will .NET handle this object AlertID. Outside of .NET should one manually dispose of the object after use (near the end of the sub). I want to ensure I become a knowledgeable programmer that does not just rely upon garbage collection. Am I over thinking this? Am I focusing on the wrong things?

• Is the use of explicit ' == true' comparison always bad? [closed]

  - by Slomojo

  Possible Duplicate: Make a big deal out of == true? I've been looking at a lot of code samples recently, and I keep noticing the use of... if( expression == true ) // do something... and... x = ( expression == true ) ? x : y; I've tended to always use... x = ( expression ) ? x : y; and... if( expression ) // do something... Where == true is implicit (and obvious?) Is this just a habit of mine, and I'm being picky about the explicit use of == true, or is it simply bad practice?

• Should I be concerned that I can't program very fast without Google? [closed]

  - by seth

  Possible Duplicate: Google is good or bad for programmer? I'm currently in college to be a software engineer, and one of the main principles taught to us is how to learn for ourselves, and how to search the web when we have a doubt. This leads to a proactive attitude - when I need something, I go get it. Recently, I started wondering how much development would I be able to do without internet access and the answer bugged me quite a bit. I know the concept of the languages and how to use them, but I was amazed by how "slow" things were without having the Google to help in the development. Most of the problems I have are related to specific syntax. For example, reading and writing to a file in Java. I have done this about a dozen times in my life, yet every time I need to do it, I end up googling "read file java" and refreshing my memory. I completely understand the code and fully understand what it does, but I am sure that without Google it would take me a few tries to get the code correct. Is this normal? Should I be worried and try to change something in my programming behaviour?

• HTML5 article tag application for the iPad

  - by dspencer

  I've used article tags on websites. My understanding and practice is to use the article tag for publication content. I always use HTML/HTML5 tags as their intended purposes and not at will. Recently, I've seen an HTML template that uses the article tag for the non-publication page content such as the content of an About Us page or any other generic page. I asked the why it was used this way and the (vague) explanation was that it had to do with the way the iPad read the tag. Is this true?

• Are there new flexible texteditors? [closed]

  - by RParadox

  Vi(m) and Emacs are almost 40 years old. Why are they still the standard, and what attempts have been made at coming up with a new flexible editor? Are there any features which can not be built into vim/emacs? My question is similar to this one: Time to drop Emacs and vi? No one had a suggestion, which surprises me. I would have thought that the core of a texteditor is very small and that people brew their own. Perhaps nobody wants to deal with supporting all the modes? Edit to clarify my question: Instead of writing modes and scripts I ask myself, why there is not a much lightweight project, which lets people custom the editor more directly? Vim has 365395 LOC (C lines all included), Emacs 1.5 million LOC. Why is there a project with say 50k LOC, which is the core, why people can use more freely? Perhaps there is such project, I haven't looked very far. I thought about putting together modules from Vim myself and experimenting with some ideas. The core of editing shouldn't be more than 10k? Vim has a lot optimizations which is really an overkill nowadays. Basically I'm looking for a code base for my own editor and Vi/Emacs are I believe not intended to be used in this way. Bill Joy said the following about vi. http://web.cecs.pdx.edu/~kirkenda/joy84.html The fundamental problem with vi is that it doesn't have a mouse and therefore you've got all these commands. In some sense, its backwards from the kind of thing you'd get from a mouse-oriented thing. I think multiple levels of undo would be wonderful, too. But fundamentally, vi is still ed inside. You can't really fool it. Its like one of those pinatas - things that have candy inside but has layer after layer of paper mache on top. It doesn't really have a unified concept. I think if I were going to go back - I wouldn't go back, but start over again.

• Should I create inner class here or leave as is?

  - by AndroidNoob

  Folks, I have two separate classes. One of them makes http requests/receives response to/from a server and the second one converts received JSON objects into my models (separate classes). I'm thinking it would be an idea to include this class for data converting as an inner class of my first class. Wouldn't my first class be extra big because of it and I need to leave everything as is or this is a good common practice to behave like that?

• Is it a bad practice to have an interface to define constants?

  - by FabianB

  I am writing a set of junit test classes in java. There are several constants, for example strings that I will need in different test classes. I am thinking about an interface that defines them and every test class would implement it. The benefits I see there are: easy access to constants: "MY_CONSTANT" instead of "ThatClass.MY_CONSTANT" each constant defined only once Is this approach rather a good or bad practice? I feel like abusing the concept of interfaces a little bit. You can answer generally about interfaces/constants, but also about unit tests if there is something special about it.

• How do you balance between "do it right" and "do it ASAP" in your daily work?

  - by Flot2011

  I find myself pondering this question times and times again. I want to do things the right way, to write a clean, understandable, correct code that is easy to maintain, but what I really do pretty often is writing a patch upon patch just because there is no time, clients are waiting, a bug should be fixed overnight, the company is losing money on this problem, a manager is pressing hard etc. etc. I know perfectly well that in a long shot I am wasting much more time on these patches, but as this time is spread over months of work, nobody cares. Also, as one of my managers used to say, we don't know if there will be this long shot if we will not fix it now. I am sure I am not the only one entrapped in this endless real/ideal choices. So how you, fellow programmers, are coping with this?
