• Why do people think SOAP is deprecated?

  - by user98q37479

  While browsing SO today I found this question here and it starts with this: Sure, you're gonna tell me that SOAP is depracated and all, well i'm forced to use it Found lots of statement like this one on SO up till now, this one just triggered me to ask this question. REST has its uses, SOAP has its uses, in some places they intersect as functionality but they are not replaceable to one another. So I wonder, why do people think SOAP is "deprecated"? Is it ignorance? Complexity of SOAP and WS-* specs? REST hype? What? If you think SOAP is deprecated please tell me why. I'm curious!

• Why are we as an industry not more technically critical of our peers? [closed]

  - by Jarrod Roberson

  For example: I still see people in 2011 writing blog posts and tutorials that promote setting the Java CLASSPATH at the OS environment level. I see people writing C and C++ tutorials dated 2009 and newer and the first lines of code are void main(). These are examples, I am not looking for specific answers to the above questions, but to why the culture of accepting sub-par knowledge in the industry is so rampant. I see people posting these same type of empirically wrong suggestions as answers on www.stackoverflow.com and they get lots of up votes and practically no down votes! The ones that get lots of down votes are usually from answering a question that wasn't asked because of lack of reading for comprehension skills, and not incorrect answers per se. Is our industry that ignorant as a whole, I can understand the internet in general being lazy, apathetic and un-informed but our industry should be more on top of things like this and way more critical of people that are promoting bad habits and out-dated techniques and information. If we are really an engineering discipline, why aren't people held to a higher standard as they are in other engineering disciplines? I want to know why people accept bad advice, poor practices as the norm and are not more critical of their peers in the software industry.?

• Is there a variable width font that does not change width when adding effects like bold, italic?

  - by George Bailey

  NetBeans has a word wrap feature now - but if the font changes width when bold then it gets all jumpy and sometimes hard to work with. Edit: It turns out that even with Courier New that NetBeans word wrap still jumps up and down lines at a time at random. I guess that this question no longer cares for an answer. However,, it seems that there is no answer. (at least nobody has brought one up yet) I am currently using Comic Sans MS which gets wider when bold.

• When not to use Spring to instantiate a bean?

  - by Rishabh

  I am trying to understand what would be the correct usage of Spring. Not syntactically, but in term of its purpose. If one is using Spring, then should Spring code replace all bean instantiation code? When to use or when not to use Spring, to instantiate a bean? May be the following code sample will help in you understanding my dilemma: List<ClassA> caList = new ArrayList<ClassA>(); for (String name : nameList) { ClassA ca = new ClassA(); ca.setName(name); caList.add(ca); } If I configure Spring it becomes something like: List<ClassA> caList = new ArrayList<ClassA>(); for (String name : nameList) { ClassA ca = (ClassA)SomeContext.getBean(BeanLookupConstants.CLASS_A); ca.setName(name); caList.add(ca); } I personally think using Spring here is an unnecessary overhead, because The code the simpler to read/understand. It isn't really a good place for Dependency Injection as I am not expecting that there will be multiple/varied implementation of ClassA, that I would like freedom to replace using Spring configuration at a later point in time. Am I thinking correct? If not, where am I going wrong?

• Why is iOS "jailbreaking" CPU specific? [closed]

  - by Ted Wong

  Recently, iOS 6 was "jailbroken" but only on the Apple A4 CPU. Why is the "jailbreaking" process specific to a CPU? From Wikipedia: ... "iOS jailbreaking is the process of removing the limitations imposed by Apple on devices running the iOS operating system through the use of hardware/software exploits – such devices include the iPhone, iPod touch, iPad, and second generation Apple TV. Jailbreaking allows iOS users to gain root access to the operating system""" ...

• Application Development: Python or Java (or PHP)

  - by luckysmack

  I'm looking to get into application development, such as Facebook or Android apps and games. I am doing this for fun and to learn. Once my skills are to par I would like to have some side income from the apps, but I'm not banking on living off that (just so you know where I'm coming from and know what my end goals are). Currently I know and am familiar with PHP and frameworks such as cakephp and yii. However, I have been wanting to learn another language to broaden my horizons and to become a better developer. So I have narrowed it down to 2 languages. Python, and Java (I can already hear people cringing at the difference in the languages I have chosen, but I have some reasons). Python: closer to PHP that Java. Cross platformability. Also great as a general scripting language and has many file system level benefits that PHP does not. Cleaner syntax, readability, blah blah and the list goed on. Python will work great for cross platform apps and can be run on many OS's and is supported by Facebook for app development. But there is no support on Android (for full fledged apps). Java: a much stronger typed language, very robust community and corporate backing. Knowing Java is also good for personal marketability for enterprises, if you're into that. The main benefit here is that Java can write apps natively for Android and the apps can be ported for web versions to play on Facebook. So while I have seen many developers prefer Java over the two, Java has this significant advantage, where I can market my apps in both markets and in the future build more potential income. But like I said it is for fun. While money isn't the goal, it would still be nice. PHP: I'm putting this here because I know it already, and I'm sure a case could be made for it. It obviously works great for Facebook but like Python does not do so well on android. While it's mostly the realm of 'application development' that appeals to me, I do find Android apps fairly interesting and something that has a ton of potential to. But then again Facebook has a ton more users and the apps can also potentially be more immersive (desktop vs. mobile). So this is why I'm kinda stuck on what route to choose. Python for Facebook and web apps, with likely faster development to production times, or Java which can be developed for any of the platforms to make apps. Side note: I'm not really trying to get into 3D development, mostly 2D. And I also want to make an app with real-time play (websockets, etc). Someone mentioned node, js to me for that but Python seems to be more globally versatile for my goals. So, to anyone that does Facebook or Android development in either language: what do you suggest? Any input is valuable and I do appreciate it. And sorry for being long winded. EDIT: as mentioned in one of the answers, my primary goal is gaming. Although I do have some plans for non gaming apps such as general web based and desktop based ones. But gaming is my main goal with the possibility of income. EDIT: Another consideration could be Jython. Writing Python code which is converted into Java bytecode. This would allow the ability to do Android apps using Python. I could be wrong though, I'm still looking into it. Update 1-26-11: I recently acquired a new job which required I learn .NET using C#. Im sure some of you are cringing already but I really like the whole system and how it all works together between desktop and web development. But, as I am still interested in Python very much, and after some research I have decided I will learn Python as well as the IronPython implementation for .NET. But (again: I know...) since .NET is mostly a Windows thing and not as cross-compatible as I like, I will be learning Mono which is a cross platform implementation of .NET where I can use what I learn at work using C# and what I want to learn, Python/IronPython. So while learning and writing C#/.NET @ work I will be learning Python - Mono - Iron Python for what I want to do personally. And the benefit of them all being very closely related will help me out a lot, I think. What do you guys think? I almost feel like that should be another question, but there's not much of a question. Either way, you guys gave very helpful input.

• Would I be able to use code hosting services to host malware code?

  - by NlightNFotis

  Let me start by saying that I am a computer security researcher. Part of my job is to create malware to deploy on a controlled environment in order to study or evaluate several aspects of computer security. Now, I am starting to think that using an online code hosting service (such as BitBucket, Github, etc...) to have all my code in 1 place, would allow me to work on my projects more efficiently. My question is: Are there any issues with this? I have studied those companies' privacy policies, and they state that they allow usage of their services for lawful usage. Since I am not distributing malware, but I am only using it on my machines and machines that I am authorized to use, aren't I allowed to use the service? For the usage that I am doing, malware is the same as any other software. I recognise that I should be extremely careful with code hosting, as any mistake from my part could hold me liable for damages and leave me open against legal action. As such I am recognizing that I should use private repositories, so the code is not available to the public. But how private is a private repository? How can I trust that companies like them will not leak or sell a potential (electronic) viral weaponry that I may have created in the future?

• Graduated transition from Green - Yellow - Red

  - by GoldBishop

  I have am having algorithm mental block in designing a way to transition from Green to Red, as smoothly as possible with a, potentially, unknown length of time to transition. For testing purposes, i will be using 300 as my model timespan but the methodology algorithm design needs to be flexible enough to account for larger or even smaller timespans. Figured using RGB would probably be the best to transition with, but open to other color creation types, assuming its native to .Net (VB/C#). Currently i have: t = 300 x = t/2 z = 0 low = Green (0, 255, 0) mid = Yellow (255, 255, 0) high = Red (255, 0, 0) Lastly, sort of an optional piece, is to account for the possibility of the low, mid, and high color's to be flexible as well. I assume that there would need to be a check to make sure that someone isnt putting in low = (255,0,0), mid=(254,0,0), and high=(253,0,0). Outside of this anomaly, which i will handle myself based on the best approach to evaluate a color. Question: What would be the best approach to do the transition from low to mid and then from mid to high? What would be some potential pitfalls of implementing this type of design, if any?

• Role of linking, object files and executables

  - by Tim

  For a C or assembly program that does not require any other library, will linking be necessary? In other words, will conversion from C to Assembly and/or from Assembly to an object file be enough without being followed by linking? If linking is still needed, what will it do, given that there is just one object file which doesn't need a library to link to? Relatedly, how different are object files and executable files, given that in Linux, both have file format ELF? Are object files those ELF files that are not runnable? Are there some executable files that can be linked to object files? If yes, does it mean dynamical linking of executables to shared libraries?

• Is reference to bug/issue in commit message considered good practice?

  - by Christian P

  I'm working on a project where we have the source control set up to automatically write notes in the bug tracker. We simply write the bug issue ID in the commit message and the commit message is added as a note to the bug tracker. I can see only a few downsides for this practice. If sometime in the future the source code gets separated from the bug tracking software (or the reported bugs/issues are somehow lost). Or when someone is looking in the history of commits but doesn't have access to our bug tracker. My question is if having a bug/issue reference in the commit message is considered good practice? Are there some other downsides?

• Process arbitrarily large lists without explicit recursion or abstract list functions?

  - by Erica Xu

  This is one of the bonus questions in my assignment. The specific questions is to see the input list as a set and output all subsets of it in a list. We can only use cons, first, rest, empty?, empty, lambda, and cond. And we can only define exactly once. But after a night's thinking I don't see it possible to go through the arbitrarily long list without map or foldr. Is there a way to perform recursion or alternative of recursion with only these functions?

• Changing my Sun SCJP certification to an Oracle one?

  - by Gugussee

  I hold a Sun SCJP from ten years ago or so. At first it was supposed to be a temporary certification (valid for a few years, I don't remember exactly: all I remember is that I had an expiration date on my certification card) then Sun changed their mind and decided the SCJP was lifetime valid. Another SCJP programmer told me I could change my cert so I contacted Sun (there was a procedure for that that I don't remember either) and received my new SCJP (without any expiration date). Now that Oracle bought Sun I was wondering: can I get somehow a Oracle/Sun SCJP paper/card/badge whatever knowing that I do own a SCJP? If anyone here holding an old SCJP changed it to an Oracle/Sun one (if such a thing exist), I'd be interested to hear what can be done. (btw I'm new here so I cannot create a new tag: maybe someone with more rep could create a Sun tag?)

• What threading pratice is good 90% of the time?

  - by acidzombie24

  Since my SO thread was closed i guess i can ask it here. What practice or practices are good 90% of the time when working with threading with multiple cores? Personally all i have done was share immutable classes and pass (copy) data to a queue to the destine thread. Note: This is for research and when i say 90% of the time i dont mean it is allowed to fail 10% of the time (thats ridiculous!) i mean 90% it is a good solution while the other 10% it is not so desirable due to implementation or efficiently reasons (or plainly another technique fits the problem domain a lot better).

• How to Get Myself Up to Speed in Building a Java Web App

  - by Damian Wells

  I'm a new developer at a fairly large company and I'm working on a Java Web Application with a senior developer there. The Web App is built on top of an IBM stack (RAD, DB2, WebSphere) and basically uses JSPs and Servlets. The Web App is an internal tool to be used by employees to manage data coming from Excel files. So, there are lots of database interaction going around like SQL commands. My question is: I don't know much about JavaEE as a whole and only know a little about JSPs and Servlets and I would like to get myself up to speed so I can understand and contribute to the Web App as fast as I could. What resources (tutorials, links, etc) should I be looking at? Am I supposed to get a book about JavaEE or something that focuses just on JSPs and Servlets?

• How can I move towards the Business Intelligence/ data mining fields from software developer [closed]

  - by user1758043

  I am working as a Python developer and I work with django. I also do some web scraping and building spiders and bots. Now from there I want to make my move to Business Intelligence. I just want to know how I can move into that field. Because as companies are not going to hire me in that field directly, I just want to know how can I make the transistion. I was thinking of first working as Database developer in SQL and then I can see further. But I want advice from you guys so that I can start learning that stuff so that I can change jobs keeping that in mind. Here in my area there are plenty of jobs in all areas but I need to know how to transition and what things I should learn before making that transition. Here jobs are plenty so if I know my stuff, getting a job is a piece of cake because they don't have any people. Same jobs keep getting advertised for months and months.

• Advice needed: Software Development [closed]

  - by Hunter McMillen

  I recently graduated from college with a B.S. in Computer Science, and am now currently attending the same college to get an M.S. in Computer Science. I know lots of things about Computer Science and programming but throughout all of my coursework I have never had to develop a single complete application, the projects were always relatively small (~300-500 lines of code). Basically, my overall I am about to have these two degrees and I feel like I don't know anything about software development or design; which doesn't make a whole lot of sense. I am looking for ways to fill in the gaps in my knowledge, I would love people's advice on these questions: 1) How do you design good software? Where do you start? 2) What makes a good software developer? Sorry for the convoluted question, but in my mind it is a convoluted situation. Thanks Edit Thanks everyone for your advice.

• "continue" and "break" for static analysis

  - by B. VB.

  I know there have been a number of discussions of whether break and continue should be considered harmful generally (with the bottom line being - more or less - that it depends; in some cases they enhance clarity and readability, but in other cases they do not). Suppose a new project is starting development, with plans for nightly builds including a run through a static analyzer. Should it be part of the coding guidelines for the project to avoid (or strongly discourage) the use of continue and break, even if it can sacrifice a little readability and require excessive indentation? I'm most interested in how this applies to C code. Essentially, can the use of these control operators significantly complicate the static analysis of the code possibly resulting in additional false negatives, that would otherwise register a potential fault if break or continue were not used? (Of course a complete static analysis proving the correctness of an aribtrary program is an undecidable proposition, so please keep responses about any hands-on experience with this you have, and not on theoretical impossibilities) Thanks in advance!

• MVP Pattern Philsophical Question - Security Checking in UI

  - by Brian

  Hello, I have a philosophical question about the MVP pattern: I have a component that checks whether a user has access to a certain privilege. This privilege turns on or off certain UI features. For instance, suppose you have a UI grid, and for each row that gets bound, I do a security check to see if certain features in the grid should be enabled or disabled. There are two ways to do this: have the UI/view call the component's method, determine if it has access, and enable/disable or show/hide. The other is have the view fire an event to the presenter, have the presenter do the check and return the access back down to the view through the model or through the event arg. As per the MVP pattern, which component should security checks fit into, the presenter or the view? Since the view is using it to determine its accessibility, it seems more fitting in the view, but it is doing database checks and all inside this business component, and there is business logic there, so I can see the reverse argument too. Thoughts? Thanks.

• When to do Code Review

  - by mcass20

  We have recently moved to a scrum process and are working on tasks and user stories inside of sprints. We would like to do code reviews frequently to make them less daunting. We are thinking that doing them on a user story level but are unsure how to branch our code to account for this. We are using VS and TFS 2010 and we are a team of 6. We currently branch for features but are working on changing to branching for scrum. We do not currently use shelvesets and don't really want to implement if there are other techniques available. How do you recommend we implement code review per user story?

• Is 'Protection' an acceptable Java class name

  - by jonny

  This comes from a closed thread at stack overflow, where there are already some useful answers, though a commenter suggested I post here. I hope this is ok! I'm trying my best to write good readable, code, but often have doubts in my work! I'm creating some code to check the status of some protected software, and have created a class which has methods to check whether the software in use is licensed (there is a separate Licensing class). I've named the class 'Protection', which is currently accessed, via the creation of an appProtect object. The methods in the class allow to check a number of things about the application, in order to confirm that it is in fact licensed for use. Is 'Protection' an acceptable name for such a class? I read somewhere that if you have to think to long in names of methods, classes, objects etc, then perhaps you may not be coding in an Object Oriented way. I've spent a lot of time thinking about this before making this post, which has lead me to doubt the suitability of the name! In creating (and proof reading) this post, I'm starting to seriously doubt my work so far. I'm also thinking I should probably rename the object to applicationProtection rather than appProtect (though am open to any comments on this too?). I'm posting non the less, in the hope that I'll learn something from others views/opinions, even if they're simply confirming I've "done it wrong"!

• Develop secureness first or as a later step?

  - by MattyD

  The question Do you actively think about security when coding? asks about security mindset while programming. Obviously, a developer does need to think about security while coding — SQL injection, password security, etc. However, as far as the real, fully-formed security, especially the tricky problems that may not be immediately obvious, should I be concerned with tackling these throughout the development process, or should it be a step of its own in later development? I was listening to a podcast on Security Now and they mentioned about how a lot of the of the security problems found in Flash were because when Flash was first developed it wasn't built with security in mind (because it didn't need to) — therefore Flash has major security flaws at its core. I know that no one would want to actively disagree with "think security first" as a best practice, but many companies do not follow best practices. So, what is the correct approach to balance between needing to get the product done and developing it securely?

• Designing Content-Based ETL Process with .NET and SFDC

  - by Patrick

  As my firm makes the transition to using SFDC as our main operational system, we've spun together a couple of SFDC portals where we can post customer-specific documents to be viewed at will. As such, we've had the need for pseudo-ETL applications to be implemented that are able to extract metadata from the documents our analysts generate internally (most are industry-standard PDFs, XML, or MS Office formats) and place in networked "queue" folders. From there, our applications scoop of the queued documents and upload them to the appropriate SFDC CRM Content Library along with some select pieces of metadata. I've mostly used DbAmp to broker communication with SFDC (DbAmp is a Linked Server provider that allows you to use SQL conventions to interact with your SFDC Org data). I've been able to create [console] applications in C# that work pretty well, and they're usually structured something like this: static void Main() { // Load parameters from app.config. // Get documents from queue. var files = someInterface.GetFiles(someFilterOrRegexPattern); foreach (var file in files) { // Extract metadata from the file. // Validate some attributes of the file; add any validation errors to an in-memory // structure (e.g. List<ValidationErrors>). if (isValid) { // Upload using some wrapper for an ORM an someInterface.Upload(meta.Param1, meta.Param2, ...); } else { // Bounce the file } } // Report any validation errors (via message bus or SMTP or some such). } And that's pretty much it. Most of the time I wrap all these operations in a "Worker" class that takes the needed interfaces as constructor parameters. This approach has worked reasonably well, but I just get this feeling in my gut that there's something awful about it and would love some feedback. Is writing an ETL process as a C# Console app a bad idea? I'm also wondering if there are some design patterns that would be useful in this scenario that I'm clearly overlooking. Thanks in advance!

• When to skip solving the general problem and settling for the specific problem?

  - by Peter Smith

  I've been working hard on trying to develop a general solution to my problem, but I cannot seem to formulate a proper algorithm for it, at least one that doesn't take a ton of inaccurate grunt work building a lookup table. I have a solution already for the specific requirement, but it requires the software's configuration to be changed every time the software is loaded with a different geographic area's datasets. So is it better to be finished and move on for now, or to keep attempting to solve the general problem knowing that the specific problems will keep popping up?

• Fast set indexing data structure for superset retrieval

  - by Asterios

  I am given a set of sets: {{a,b}, {a,b,c}, {a,c}, {a,c,f}} I would like to have a data structure to index those sets such that the following "lookup" is executed fast: find all supersets of a given set. For example, given the set {a,c} the structure would return {{a,b,c}, {a,c,f}, {a,c}} but not {a,b}. Any suggestions? Could this be done with a smart trie-like data structure storing sets after a proper sorting? This data structures is going to be queried a lot. Thus, I'm searching for a structure that might be expensive in build but rather fast to query.

• Most appropriate OSS license for infrastructure code

  - by Richard Szalay

  I'm looking into potentially releasing some infrastructure code (related to automated builds and deployments) as OSS and I'm curious about how the various OSS licenses effect it. Specifically, LGPL prevents the code itself (part/whole) being modified into a commercial product (which is what I'm after), but allows it to be "linked to" in the creation of commercial products (also ok). How does the "linked to" clause relate to infrastructure code, which is not deployed with the product itself? Would the application still be required to provide "appropriate legal notices" (which I'm not fussed over)? Would I be better off looking at the Eclipse Public License?
