• Which specific practices could be called "software craftsmanship" rather than "software engineering"?

  - by FinnNk

  Although not a new idea there seems to have been a big increase in the interest in software craftsmanship over the last couple of years (notably the often recommended book Clean Code's full title is Clean Code: A Handbook of Agile Software Craftsmanship). Personally I see software craftsmanship as good software engineering with an added interest in ensuring that the end result is a joy to work with (both as an end user and as someone maintaining that software) - and also that its focus is more at the coding level of things than the higher level process things. To draw an analogy - there were lots of buildings constructed in the 50s and 60s in a very modern style which took very little account of the people who would be living in them or how those buildings would age over time. Many of those buildings rapidly developed into slums or have been demolished long before their expected lifespans. I'm sure most developers with a few years under their belts will have experienced similar codebases. What are the specific things that a software craftsman might do that a software engineer (possibly a bad one) might not?

• Which stages of the requirements analysis process in mobile requirements engineering are the most challenging ones?

  - by user363295

  I'm doing a research on formulating a requirements analysis model as a stage of requirements engineering for mobile-application development by considering the limitations and the needs of it ( agility and etc.. .), what I'm trying to figure out is that which parts of this process (requirements analysis for mobile development) are the most challenging ones ( so i can focus more on) , and if there is any stage that u think I need to include or exclude (exp. some may think a quality plan may or may not be necessary and etc.) to make it more clear below is the list of few of the areas in which I can focus on ( by the way your suggestions can be anything out of the below list.) -Requirements specification -Prototyping -Requirements Prioritization -Focusing on quality functions

• Transitioning from Chemical engineering to software industry what to do??

  - by console cowboy

  Hello all. Currently I am in my last semester of Engineering & has made my mind to switch to software field but given my knowledge of programming limited only to C. I am confused what to do next.Currently i have two choices. Get good at C, learn Python & write some good code/Apps & increase my employability chances. Do some Java/.Net certifications to increase my employability chances? Any kind of advice/suggestion is highly welcomed. P.S:I am also good at Linux & have a above average knowledge of operating systems. P.p.s: Advice from Indian Programmers would be beneficial.

• How can I avoid the engineering mistakes of PDT?

  - by ashy_32bit

  As a developer with enough experience to evaluate a tool, I may say that PDT is very huge in size and slow in performance for a PHP IDE. It gets bigger by release and exponentially slower by the size of the projects. Add some extra syntax coloring rules and it literally crawls, code completion works randomly and building workspace takes like forever. Java black magic (-Xmx etc) eases the pain a little but that's it. So my questions are: Why is PDT like this? What design or engineering factors led to its poor performance? How can I avoid making these same mistakes in my own products?

• How to calculate line count for project

  - by sixtyfootersdude

  I am taking a software engineering class right now. Our assignment is to evaluate Mozilla's Thunderbird. Our assignment is to evaluate the size of Thunderbird. One metric that we need to use is the number of lines of code in the project. (Lines of code meaning not including comments or new lines). Is there a standard way to find the number of lines or am I better off just cracking out a script to do this? I think that I could do something like this: # remove all comments find -name *.java | \ sed "/\/*/,\*\// s/.*//g | \ # remove multiline comments sed s/\/\///g # remove single line comments # count not empty lines find -name *.java | grep -c "<character>" But I would need to do that for each file type. It seems like there should be some utility that does that already. (something mac/unix compatible would be preferable).

• How can I write good "research code"?

  - by John

  "Research code" is often held up as a paragon of what not to do when writing software. Certainly, the kind of code that often results from trying to solve a research problem can end up being poorly-designed, difficult to debug, etc. But my question is this: does research code have to be this way? Is it possible to write good research code? Is the only approach to consider the first version a poorly-written prototype to be discarded in favour of the better-designed second version? Software engineering has all sorts of best practices about how to design and write good code, but I don't usually find this relevant when you don't have a good idea ahead of time what the final system will look like. The final system is likely to be a result of what did or didn't work along the way, and the only way to determine what does or doesn't work is to write the code first. As you find things that don't work, you change what the final system looks like, moving further away from your original design (assuming you had one). I'd be interested in any personal experience with these issues, as well as any books or other resources anyone can point me to.

• how to design and produce enterprise software in Java Technology EE ? more importantly does it have

  - by fwfwfw

  I want to be able to design and produce enterprise software/applications. Java EE comes to mind. but are there alternatives ? Does it have to be J2EE, to make enterprisey software ? More importantly, how common is it for developers to use Java Technology in order to build enterprise software ? I mean how much "meat" do you need to pack before you can charge a $100,000 sticker price ? is bloatware common in this industry ? what is the best way I can learn the entire Java Enterprise and be able to design and produce enterprise software ? Or perhaps an alternative to Java ? I am starting software engineering in University, but I have personal coding experience....i just would love to be able to design enterprise software using Java Technology....i can pick up books and start practicing.....i just dont know where to begin or what to expect. My goal is to get as much experience in enterprise software field, and specialize into niches start my own company. so far i know enterprise software sale process usually take at least a couple of months but for a good reason..

• What relationship do software Scrum or Lean have to industrial engineering concepts like theory of constraints?

  - by DeveloperDon

  In Scrum, work is delivered to customers through a series of sprints in which project work is time boxed to a fixed number of days or weeks, usually 30 days. In lean software development, the goal is to deliver as soon as possible, permitting early feedback for the next iteration. Both techniques stress the importance of workflow in which software work product does not accumulate in development awaiting release at some future date. Both permit new or refined requirements and feedback from QA and customers to be acted on with as little delay as possible based on priority. A few years ago I heard a lecture where the speaker talked briefly about a family of concepts from industrial engineering called theory of constraints. In the factory, they use an operations model based on three components: drum, buffer, and rope. The drum synchronizes work product as it flows through the system. Buffers that protect the system by holding output from one stage as it waits to be consumed by the next. The rope pulls product from one work station to the next. Historically, are these ideas part of the heritage of Scrum and Lean, or are they on a separate track? It we wanted to think about Scrum and Lean in terms of drum-buffer-rope, what are the parts? Drum = {daily scrum meeting, monthly release)? Buffer = {burn down list, source control system)? Rope = { daily meeting, constant integration server, monthly releases}? Industrial engineers define work flow in terms of different kinds of factories. I-Factories: straight pipeline. One input, one output. A-Factories: many inputs and one output. V-Factories: one input, many output products. T-Plants: many inputs, many outputs. If it applies, what kind of factory is most like Scrum or Lean and why?

• Are there currently any modern, standardized, aptitude test for software engineering?

  - by Matthew Patrick Cashatt

  Background I am a working software engineer who is in the midst of seeking out a new contract for the next year or so. In my search, I am enduring several absurd technical interviews as indicated by this popular question I asked earlier today. Even if the questions I was being asked weren't almost always absurd, I would be tired nonetheless of answering them many times over for various contract opportunities. So this got me thinking that having a standardized exam that working software professionals could take would provide a common scorecard that could be referenced by interviewers in lieu of absurd technical interview questions (i.e. nerd hazing). Question Is there a standardized software engineering aptitude test (SEAT??) available for working professionals to take? If there isn't a such an exam out there, what questions or topics should be covered? An additional thought Please keep in mind, if suggesting a question or topic, to focus on questions or topics that would be relevant to contemporary development practices and realistic needs in the workforce as that would be the point of a standard aptitude test. In other words, no clown traversal questions.

• I've got my Master's in Software Engineering... Now what? [closed]

  - by Brian Driscoll

  Recently I completed a Master of Science in Software Engineering from Drexel University (Philadelphia, PA, US), because I wanted to have some formal education in software (my undergrad is in Math Ed) and also because I wanted to be able to advance my career beyond just programming. Don't get me wrong; I love to code. I spend a lot of my spare time coding. However, for me writing code is just a means to an end: what I REALLY love is designing software. Not visual design, mind you, but the architecture of the system. So, ideally I'd like to try to get a job doing software architecture. The problem is that I have no real experience in it besides my graduate course work. So, what should I do to make my "bones" in software architecture? UPDATE Just so it's clear, I have over 5 years of work experience in software development and an MCTS cert in addition to my education, so I'm not looking for the usual "I'm fresh out of school, what should I do?" advice.

• Static when metal USB plug touches my case, and other electrical problems.

  - by Archagon

  I have an aluminum PC case. Whenever the metal USB plug from my external drive contacts the front, I get crackling from my speakers, which are connected to an external USB soundcard. (This crackling happens even if they're not connected to the actual output jack.) A few possibly related problems: my audio occasionally starts popping once every few minutes, and my USB devices sometimes play the "connected" sound in Windows even though they're already connected, as if they're briefly disconnecting. My guess is that this has to do with the grounding, but I'm not sure exactly what to do. My case has a round grounding wire, but I don't know where to attach it, and fiddling with it didn't seem to have any effect. Suggestions?

• What area of Software Engineering are you going to focus your research on?

  - by ultrajohn

  hi guys! I have this very subjective question regarding software engineering. Let's say you want to pursue a graduate degree i.e. master degree with a major in software engineering, what particular topic or area of research in the field are your going to pursue? From your experience, what are the different aspects of software engineering which are vital in our field that are "under"(less) research. I know this is very subjective, I just want to elicit ideas from you guys whom I think knows a lot about the field. Thanks a lot.

• Design for a machine learning artificial intelligence framework

  - by Lirik

  This is a community wiki which aims to provide a good design for a machine learning/artificial intelligence framework (ML/AI framework). Please contribute to the design of a language-agnostic framework which would allow multiple ML/AI algorithms to be plugged into a single framework which: runs the algorithms with a user-specified data set. facilitates learning, qualification, and classification. allows users to easily plug in new algorithms. can aggregate or create an ensemble of the existing algorithms. can save/load the progress of the algorithm (i.e. save the network and weights of a neural network, save the tree of a decision tree, etc.). What is a good design for this sort of ML/AI framework?

• Good projects to learn OCaml and F#

  - by Yin Zhu

  After learning the basic syntax, reading some non-trivial code is a fast way to learn a language. We can also learn how to design a library/software during reading others' code. I have following lists. A Chess program in OCaml by Tomek Czajka. Hal Daumé has written several machine learning libraries in Ocaml. Including decision trees, logistic regression and SVM. All of them are near-production-quality code. A Chess Game Analysis program in F# in Microsoft Research. The above three are my favorites. Will you suggest some other sources? General purpose open source software are good, specialized open source like the three I list here are even more welcome.

• How to prove writing specifications beats code cowboys?

  - by Andrew Grant

  So I have a problem. Or rather my friend has a problem, since I would never write about my company on an internet forum. At my friend's company specification writing is, shall we say, a little underused. There's a deeply ingrained culture of writing code first and asking questions later, whether it's for a library routine or a new tool to inflict on their long suffering designers. This of course leads to situations where functionality is partially correct, incorrect, or just completely missing ("oh, just save before trying anything you may want to undo"). This usually results in a loss of productivity for those poor designers, or beta periods where bug-fixing is largely spent implementing things correctly. My friend's found his suggestions of writing (and testing against) specifications to be generally well received. Most of his colleagues have embraced the wonderful feeling of discovering false-assumptions on paper, instead of at 11pm on a Sunday in the middle of beta. Viva La Revolution! However there are a few who poo-poo anything that stands between their task and a keyboard. They laugh at the thought of actually designing anything, and write code with merry abandon. Mostly these are senior, long employed developers, reluctant to "waste time". The problem is that this second group of heretics invariably produce things (or at least something) quicker than the first. Subsequently this becomes justification along the lines of "It's pointless to write specifications for something as simple as an image resizer! Oh and those bugs where width!=height or the image uses RLE just need a few tweaks". And now the question :) Other than saying "told you so" at the end of a project, what are some good short-term ways to demonstrate how the practice of writing functional or technical specifications leads to better software in the long run? Cheers!

• What's wrong with the analogy between software and building construction?

  - by kuosan

  Many people like to think of building software as constructing a building so we have terms like building blocks and architecture. However, lately I've been to a couple of talks and most people say this analogy is wrong especially around the idea of having a non-coding software architect in a project. In my experience, good software architects are those who also write code so they won't design things that only looks good on paper. I've worked with several Architecture Astronauts, who have either limited or outdated experience in programming. These architecture astronauts quite often missed out critical details in their design and cause more harm than good in a project. This makes me wonder what are the differences between constructing a software and a building? How come in the building industry they can have architects who probably never build a house in their life and purely handles design work but not in the software development field?

• Books about the philosophy of software development

  - by anon

  The first time I read The Mythical Man Month, I found the book utterly boring, a waste of my time, and thought it was written by some management guru that never wrote a line of code. A few years later, I realized Fred Brooks won the Turing award. Some years after that, after a few large development projects, I started understanding what he was talking about. Are there any other books about software development on a meta/philosophical level—not in the sense of design patterns, templates, or even lisp macros—but at a level where ideas are expressed without code?

• Entrepreneur Needs Programmers, Architects, or Engineers?

  - by brand-newbie

  Hi guys (Ladies included). I posted on a related site, but THIS is the place to be. I want to build a specialized website. I am an entrepreneur and refining valuations now for venture capitalsists: i.e., determining how much cash I will need. I need help in understanding what human resources I need (i.e., Software Programmers, Architects, Engineers, etc.)??? Trust me, I have read most--if not all--of the threads here on the subject, and I can tell you I am no closer to the answer than ever. Here's my technology problem: The website will include (2) main components: a search engine (web crawler)...and a very large database. The search engine will not be a competitor to google, obviously; however, it "will" require bots to scour the web. The website will be, basically, a statistical database....where users should be able to pull up any statistic from "numerous" fields. Like any entrepreneur with a web-based vision, I'm "hoping" to get 100+ million registered users eventually. However, practically, we will start as small as feasible. As regards the technology (database architecture, servers, etc.), I do want quality, quality, quality. My priorities are speed, and the capaility to be scalable...so that if I "did" get globally large, we could do it without having to re-engineer anything. In other words, I want the back-end and the "infrastructure" to be scalable and professional....with emphasis on quality. I am not an IT professional. Although I've built several Joomla-based websites, I'm just a rookie who's only used minor javascript coding to modify a few plug-ins and components. The business I'm trying to create requires specialization and experts. I want to define the problem and let a capable team create the final product, and I will stay totally hands off. So who do you guys suggest I hire to run this thing? A software engineer? I was thinking I would need a "database engineer," a "systems security engineer", and maybe 2 or 3 "programmers" for the search engine. Also a web designer...and maybe a part-time graphic designer...everyone working under a single software engineer. What do you guys think? Who should I hire?...I REALLY need help from some people in the industry (YOU guys) on this. Is this project do-able in 6 months? If so, how many people will I need? Who exactly needs to head up this thing?...Senior software engineer, an embedded engineer, a CC++ engineer, a java engineer, a database engineer? And do I build this thing is Ruby or Java?

• <100% Test coverage - best practices in selecting test areas

  - by Paul Nathan

  Suppose you're working on a project and the time/money budget does not allow 100% coverage of all code/paths. It then follows that some critical subset of your code needs to be tested. Clearly a 'gut-check' approach can be used to test the system, where intuition and manual analysis can produce some sort of test coverage that will be 'ok'. However, I'm presuming that there are best practices/approaches/processes that identify critical elements up to some threshold and let you focus your test elements on those blocks. For example, one popular process for identifying failures in manufacturing is Failure Mode and Effects Analysis. I'm looking for a process(es) to identify critical testing blocks in software.

• Flowcharting tool/add-in for Visual Studio

  - by Rajah

  A 2 part question: Are flow-charts, as tool to analyze source-code, no longer considered useful? The reason I ask this question is that if you Google for source-code to flowchart tools for Visual Studio, there are no relevant results. Also, Microsoft does not seem to have a tool for this purpose. Are people just not using flowcharts that much any more? (I find them to be a great way to document complex logic in my code). Are there any VS tools that can take .Net (C#, VB.Net) code and convert it to a flowchart? (The only tool that I found is Aviosto's Visustin, which does not provide VS integration). Any other tools that you can recommend for this purpose?

• Test Case Design and Responsibility

  - by Sakamoto Kazuma

  So it seems like a lot of people are playing the blame game around where I work, and it brings up an interesting question. Knowns: Requirements team writes requirements for product. Developers create their own unit tests out of requirements. Testing team creates their general tests out of requirements and past customer issues. Product released if and only if X% of testcases from Testing team passes Customer response team gets bugs from the field, and lets the testing team know about these issues. Question: If the customer ends up filing a lot of defects, who is to blame? Is it the Testing team for not covering those? Or is it the requirements team for not writing better requirements? And how does one improve upon the system?
