  • Using Visual Studio as a Task-Focused IDE

    - by Jay Stevens
    Are there patterns or libraries or any official Microsoft SDK for using Visual Studio as a specifically Task-Focused UI? For example, both Revolution R (IDE for the R language) and SQL 2012 (and I think SQL 2008 and possibly 2005) use Visual Studio as the underlying IDE framework. Is there an officially supported SDK and/or examples/samples for doing this type of thing? I am building a language Parser for an existing language - whose only available IDE is INSANELY expensive - using Irony (and eventually will generate a Language Service as well). Any direct or indirect suggestions/answers are appreciated.

  • How can I make my FireFox Browser AddOn Backwards Compatible?

    - by bwheeler96
    I'm making a firefox browser add-on, and I just got all of the code working fine, but it will only install in FireFox 16, and I want it to be compatible at least from 10+, has anyone dealt with this issue? I have my package.json pointing to my install.rdf, and my install.rdf clearly states target applications. Is there any additional setup I need? here is my package.json { "name": "firefox-ext", "license": "MPL 2.0", "author": "", "version": "0.1", "fullName": "firefox-ext", "id": "jid1-AMCw25iQJof53w", "description": "a basic add-on" } and here is my install.rdf. <?xml version="1.0"?> <RDF xmlns="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:em="http://www.mozilla.org/2004/em-rdf#"> <Description about="urn:mozilla:install-manifest"> <em:id>jid1-AMCw25iQJof53w</em:id> <em:name>Generic App</em:name> <em:version>1.0</em:version> <em:type>2</em:type> <em:creator>Brian Wheeler</em:creator> <em:description>Good Stuff</em:description> <em:targetApplication> <Description> <em:id>{ec8030f7-c20a-464f-9b0e-13a3a9e97384}</em:id> <em:minVersion>1.0</em:minVersion> <em:maxVersion>19.0</em:maxVersion> </Description> </em:targetApplication> </Description> </RDF> I'm using the CFX CLI Tools to make this, so everything has been built and tested with cfx init, cfx run, and cfx xpi I just can't figure out compatibility with anything other than 16. Also, major bonus points if someone could explain the advantages of a rapid release cycle, because it really seems to have shot 3rd party Mozilla developers in the foot in terms of software compatibility. Thanks, -Brian

  • Why does void in C mean not void?

    - by Naftuli Tzvi Kay
    In strongly-typed languages like Java and C#, void (or Void) as a return type for a method seem to mean: This method doesn't return anything. Nothing. No return. You will not receive anything from this method. What's really strange is that in C, void as a return type or even as a method parameter type means: It could really be anything. You'd have to read the source code to find out. Good luck. If it's a pointer, you should really know what you're doing. Consider the following examples in C: void describe(void *thing) { Object *obj = thing; printf("%s.\n", obj->description); } void *move(void *location, Direction direction) { void *next = NULL; // logic! return next; } Obviously, the second method returns a pointer, which by definition could be anything. Since C is older than Java and C#, why did these languages adopt void as meaning "nothing" while C used it as "nothing or anything (when a pointer)"?

  • Database vs Networking

    - by user16258
    I have completed my diploma in (IT) and now pursuing degree, i am in last semester of my B.E(I.T). I want to do specialization either in Database(oracle) or in Networking(cisco). Which one of two will be in more demand in near future, i know it's all about interest but still i would like to know your opinion. Most of people say that a network engineer is never paid as better as a programmer or a DBA, and few says they do get paid well. What would be the scope if i clear my CCNA and CCNP exams, or either OCA & OCP exams, what would be more rewarding. Also i have read somewhere that most of the task of DBA will be automated so in future demand of a DBA will reduce. I would also like to hear from Network engineers what's the scenario out there in India. Thanks

  • Should I migrate to MVC3?

    - by eestein
    Hi everyone. I have a MVC2 project, my question is: should I migrate to MVC3? Why? I'd like the opinion of some who already migrated, or at least used MVC3 and MVC2. Already read http://weblogs.asp.net/scottgu/archive/2011/01/13/announcing-release-of-asp-net-mvc-3-iis-express-sql-ce-4-web-farm-framework-orchard-webmatrix.aspx and I already know about the described tool for migrating: http://blogs.msdn.com/b/marcinon/archive/2011/01/13/mvc-3-project-upgrade-tool.aspx What I'd really appreciate is your valuable insight. Best regards.

  • Project Manager that wants to lock in time estimate with a signed contract

    - by sunpech
    At a previous employment, a project manager (PM) wasn't satisfied with the delivery time of the code on a project I was on. I was told by my project lead that that the PM was considering having me sign a contract to lock-in my time estimates I gave for tasks and delivery dates. The situation on the project was that we were working with new technologies, codebase, coding standards, and very prone-to-change requirements. I was learning new things and applying them the best I could on requirements that kept on changing. The requirements throughout the iterations grew by 2-3 times, with my estimate-to-complete growing by roughly 5-8 times. The only things that didn't change were the estimates and delivery dates. Yes, I did end up missing most deadlines. And I was working on some very new technologies that no one else on the entire development team could really help out on because they wouldn't be familiar with it. At least not easily. It seemed to me then, that the PM wanted his numbers to add up-- and thus wanted me to sign a contract to "ensure" that I would always deliver working code on time. I suppose with a signed contract the PM could use it against me if I couldn't deliver on time. I believe what happened next was that other project managers and/or project leads defended me, and didn't let this happen. My question is, should this raise a red flag about the manager? Is it common practice for a manager to lock-in time estimates of a software developer with a signed contract? Or in this case, try to. Please note, I was a full time employee, not an independent consultant. Update: I want to add that I did give new estimates weekly, but it seems the original estimates and delivery dates were what the PM was fixated on.

  • Test iPhone app on iPad mini?

    - by Devfly
    I have developed an iPhone app, right now I only need a device for testing. I have 300$, and two choices - second hand iPhone 4, or brand new iPad mini. The better choice obviously is the iPad, but is it sufficient for testing iPhone apps on? On the iPad, iPhone apps can run just fine in 2X mode, but are there any differences between the app performance on iPhone and iPad (except the chipset). Should I test my app on actual iPhone, or the iPad will suffice? My app is RSS reader, not some game, so I think everything will be fine with testing on iPad mini. If I buy the iPad I will find some friends iPhone 4/3gs running iOS 5.1 (because my app's deployment target is 5.1, and the iPad comes with 6.0), but of course I can't extensively test on this iPhone. Thank you!

  • Should a Python programmer learn Ruby?

    - by C J
    Hi! I have been a Python programmer for around 1.5 years (one internship + side projects), so I am comfortable with the language. Given that everyone is talking about Ruby these days, and I mean seriously! No one bothers about Python (from what I've seen). See GitHub. All RoR. I apply for a job and they ask me about RoR. I look at the screencasts on peepcode.com and they are in Ruby. gitimmersion.com has all the tutorial in Ruby! I know this is pretty vague, but still... why Ruby! Everyone these days is obssessed with RoR! Why not Python? Anyways, my questions are: Should I learn Ruby? Is learning Ruby when knowing Python be, er, complicated for me? Or is it going to be just like learning any other language? Thanks!

  • DDD Model Design and Repository Persistence Performance Considerations

    - by agarhy
    So I have been reading about DDD for some time and trying to figure out the best approach on several issues. I tend to agree that I should design my model in a persistent agnostic manner. And that repositories should load and persist my models in valid states. But are these approaches realistic practically? I mean its normal for a model to hold a reference to a collection of another type. Persisting that model should mean persist the entire collection. Fine. But do I really need to load the entire collection every time I load the model? Probably not. So I can have specialized repositories. Some that load maybe a subset of the object graph via DTOs and others that load the entire object graph. But when do I use which? If I have DTOs, what's stopping client code from directly calling them and completely bypassing the model? I can have mappers and factories to create my models from DTOs maybe? But depending on the design of my models that might not always work. Or it might not allow my models to be created in a valid state. What's the correct approach here?

  • 32-bit / 64-bit processors - what is that feature officially called?

    - by JW01
    I see talk of CPU's being either 32-bit or 64-bit processors. Information which is often required on download pages But what is that feature officially called. i.e What's the inverse of saying "I have a 64-bit processor"? I want to say: The ??? of my processor is 64 bit What is the correct term to use for ??? I have looked at a random product on the Intel site and I suspect the correct word for this is "Instruction Set", but I'm not sure.

  • Where can I find video resources of people programming?

    - by Corey
    This might be a strange question. I'm looking for videos of people actively coding something while explaining it. However, I don't want is a beginner video that delves into what variables and objects are. Nick Gravelyn's tile engine tutorial is a great example of what I'm looking for. (He actually used to host the full, unbroken video files in his site's archive, but I guess he took them down...) I tend to learn best by "action" examples; it's difficult for me to learn by reading through documentation and text tutorials, but if I see somebody actively doing a task, I can immediately register it and apply it myself. I'm hard-of-hearing, so I would really prefer that if the video has a lot of talking, it have captioning or subtitling of some sort, or at the very least, a transcript. The tile engine videos did not have captions, but the code he was writing was very self-documenting, so I understood it for the most part. I've gone through most of the relevant GoogleDevelopers and GoogleTechTalks videos on Youtube, so those need not apply. Are there any resources out there, or even websites dedicated to this kind of thing?

  • Unable to decide weather to continue or quit and start a new carrier

    - by latif mohammad khan
    I am working in a small company. I have joined here for java developer ,but they told as i am fresher so work as Android developer . Then i asked one of my lecturer about Android developement.then he replied why going for mobile developement which is not standard(as nokia's symbain lost , mobile os changes quickly ) its better to get job as Java Developer. By listening his words i was bit not satisfied with my job and thought of leaving Job and search as java developer. But i dont have much confidence to search a job at that time(because i got job after 1 and half years after i passed out), i have decided to work as android developer(as learning new technology and practice java at home). On the first day they introduced me to team leads and they assigned under him. After few days i came to know that my team lead is having only 1 year experience. He(my team lead) joined here as a fresher and done r&d now is my Team lead. If i ask any doubt to him , he just search in internet and reply's my question (some times he explains wrongly) i correct it by myself by searching in net.In my company they don't use latest technologies,they dont follow any design patterns because they dont know them. They provide me very less pay and more work, i dont bother about pay because i am fresher but i bother about work which is not use(I feel like that because they dont use latest technologies,no design patterns,no proper team lead) What i thought was to learn from the company, Team leads how the project done. But there I feel like, i am wasting my time.If i go for another interview in future they ask latest technologies. Now i dont know what to do weather to quit the job and learn another language which have good demand like sap abap or to continue here. please provide me advice Thanks.

  • Rules and advice for logging?

    - by Nick Rosencrantz
    In my organization we've put together some rules / guildelines about logging that I would like to know if you can add to or comment. We use Java but you may comment in general about loggin - rules and advice Use the correct logging level ERROR: Something has gone very wrong and need fixing immediately WARNING: The process can continue without fixing. The application should tolerate this level but the warning should always get investigated. INFO: Information that an important process is finished DEBUG. Is only used during development Make sure that you know what you're logging. Avoid that the logging influences the behavior of the application The function of the logging should be to write messages in the log. Log messages should be descriptive, clear, short and concise. There is not much use of a nonsense message when troubleshooting. Put the right properties in log4j Put in that the right method and class is written automatically. Example: Datedfile -web log4j.rootLogger=ERROR, DATEDFILE log4j.logger.org.springframework=INFO log4j.logger.waffle=ERROR log4j.logger.se.prv=INFO log4j.logger.se.prv.common.mvc=INFO log4j.logger.se.prv.omklassning=DEBUG log4j.appender.DATEDFILE=biz.minaret.log4j.DatedFileAppender log4j.appender.DATEDFILE.layout=org.apache.log4j.PatternLayout log4j.appender.DATEDFILE.layout.ConversionPattern=%d{HH:mm:ss,SSS} %-5p [%C{1}.%M] - %m%n log4j.appender.DATEDFILE.Prefix=omklassning. log4j.appender.DATEDFILE.Suffix=.log log4j.appender.DATEDFILE.Directory=//localhost/WebSphereLog/omklassning/ Log value. Please log values from the application. Log prefix. State which part of the application it is that the logging is written from, preferably with something for the project agreed prefix e.g. PANDORA_DB The amount of text. Be careful so that there is not too much logging text. It can influence the performance of the app. Loggning format: -There are several variants and methods to use with log4j but we would like a uniform use of the following format, when we log at exceptions: logger.error("PANDORA_DB2: Fel vid hämtning av frist i TP210_RAPPORTFRIST", e); In the example above it is assumed that we have set log4j properties so that it automatically write the class and the method. Always use logger and not the following: System.out.println(), System.err.println(), e.printStackTrace() If the web app uses our framework you can get very detailed error information from EJB, if using try-catch in the handler and logging according to the model above: In our project we use this conversion pattern with which method and class names are written out automatically . Here we use two different pattents for console and for datedfileappender: log4j.appender.CONSOLE.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n log4j.appender.DATEDFILE.layout.ConversionPattern=%d [%t] %-5p %c - %m%n In both the examples above method and class wioll be written out. In the console row number will also be written our. toString() Please have a toString() for every object. EX: @Override public String toString() { StringBuilder sb = new StringBuilder(); sb.append(" DwfInformation [ "); sb.append("cc: ").append(cc); sb.append("pn: ").append(pn); sb.append("kc: ").append(kc); sb.append("numberOfPages: ").append(numberOfPages); sb.append("publicationDate: ").append(publicationDate); sb.append("version: ").append(version); sb.append(" ]"); return sb.toString(); } instead of special method which make these outputs public void printAll() { logger.info("inbet: " + getInbetInput()); logger.info("betdat: " + betdat); logger.info("betid: " + betid); logger.info("send: " + send); logger.info("appr: " + appr); logger.info("rereg: " + rereg); logger.info("NY: " + ny); logger.info("CNT: " + cnt); } So is there anything you can add, comment or find questionable with these ways of using the logging? Feel free to answer or comment even if it is not related to Java, Java and log4j is just an implementation of how this is reasoned.

  • Data structure: sort and search effectively

    - by Jiten Shah
    I need to have a data structure with say 4 keys . I can sort on any of these keys. What data structure can I opt for? Sorting time should be very little. I thought of a tree, but it will be only help searching on one key. For other keys I'll have to remake the tree on that particular key and then find it. Is there any data structure that can take care of all 4 keys at the same time? these 4 fields are of total 12 bytes and total size for each record - 40 bytes.. have memory constraints too... operations are : insertion, deletion, sorting on different keys.

  • WCF and Service Registry

    I am about to build some WCF Services. Those services need to communicate to each others too, in some scenarios. I've done some "Google-ing" about Service Registry but can't figure out how to implement service registry with WCF; is there any other alternate? Is there any Microsoft technology available for Service Registry? I'm new to SOA and I will really appreciate any help or guidance (what and where should I exactly look for registry services).

  • Data validation best practices: how can I better construct user feedback?

    - by Cory Larson
    Data validation, whether it be domain object, form, or any other type of input validation, could theoretically be part of any development effort, no matter its size or complexity. I sometimes find myself writing informational or error messages that might seem harsh or demanding to unsuspecting users, and frankly I feel like there must be a better way to describe the validation problem to the user. I know that this topic is subjective and argumentative. StackOverflow might not be the proper channel for diving into this subject, but like I've mentioned, we all run into this at some point or another. There are so many StackExchange sites now; if there is a better one, feel free to share! Basically, I'm looking for good resources on data validation and user feedback that results from it at a theoretical level. Topics and questions I'm interested in are: Content Should I be describing what the user did correctly or incorrectly, or simply what was expected? How much detail can the user read before they get annoyed? (e.g. Is "Username cannot exceed 20 characters." enough, or should it be described more fully, such as "The username cannot be empty, and must be at least 6 characters but cannot exceed 30 characters."?) Grammar How do I decide between phrases like "must not," "may not," or "cannot"? Delivery This can depend on the project, but how should the information be delivered to the user? Should it be obtrusive (e.g. JavaScript alerts) or friendly? Should they be displayed prominently? Immediately (i.e. without confirmation steps, etc.)? Logging Do you bother logging validation errors? Internationalization Some cultures prefer or better understand directness over subtlety and vice-versa (e.g. "Don't do that!" vs. "Please check what you've done."). How do I cater to the majority of users? I may edit this list as I think more about the topic, but I'm genuinely interest in proper user feedback techniques. I'm looking for things like research results, poll results, etc. I've developed and refined my own techniques over the years that users seem to be okay with, but I work in an environment where the users prefer to adapt to what you give them over speaking up about things they don't like. I'm interested in hearing your experiences in addition to any resources to which you may be able to point me.

  • Email Service or CRM

    - by MG1
    I am creating a process for a client who is a chapel. They have people who sign up to receive notifications of a death anniversary. I exported a CSV from the db, imported it into Mailchimp and I was about to launch a Mailchimp automation based on a date. Not I realized that are many instances where the same person singed up for multiple death reminders. Mailchimp doesn't allow for duplicate email addresses in one list. Is there another service or application that I can use for this?

  • Performance: recursion vs. iteration in Javascript

    - by mastazi
    I have read recently some articles (e.g. http://dailyjs.com/2012/09/14/functional-programming/) about the functional aspects of Javascript and the relationship between Scheme and Javascript (the latter was influenced by the first, which is a functional language, while the O-O aspects are inherited from Self which is a prototyping-based language). However my question is more specific: I was wondering if there are metrics about the performance of recursion vs. iteration in Javascript. I know that in some languages (where by design iteration performs better) the difference is minimal because the interpreter / compiler converts recursion into iteration, however I guess that probably this is not the case of Javascript since it is, at least partially, a functional language.

  • Why did Embarcadero make me sign a waiver?

    Just signed in to the Embarcadero Developer Network and got this: EXPORT CONTROLS ON EMBARCADERO SOFTWARE Your EDN membership and access to Embarcadero Software is subject to your agreement to and compliance with the following terms: -You agree that U.S. export control laws govern your use of the Embarcadero Software. -You are not a citizen, national, or resident of, and are not under control of, the government of Cuba, Iran, Sudan, North Korea, Syria, nor any country to which the United States has embargoed or prohibited export. -You will not provide or export Embarcadero Software, directly or indirectly, to the above mentioned countries nor to citizens, nationals or residents of those countries. -You are not listed on the United States Department of Treasury lists of Specially Designated Nationals, Specially Designated Terrorists, and Specially Designated Narcotic Traffickers, nor are you listed on the United States Department of Commerce Table of Denial Orders. -You will not provide or export the Embarcadero Software, directly or indirectly, to persons on the above mentioned lists. -You will not use the Embarcadero Software for, and will not allow the Embarcadero Software to be used for, any purposes prohibited by United States law, including for the development, design, manufacture or production of nuclear, chemical or biological weapons of mass destruction. I think it's BS, but what craziness is forcing companies like Embarcadero to hold developers to these very high standards? Also, what is "Embarcadero Software"? Does that mean I can't put a benign videogame on a website that may have a runtime that might be downloaded by a Iranian who love scrabble. Or does "Embarcadero Software" refer to anything I develop using Delphi.

  • How can i be sure that professional programming is not for me ?

    - by user17766
    Hello everybody I love programming, developing projects for hobby and learning new concepts. I am getting harder too much in current job Despite learnt many thing well. I can even hardly understand assigned tasks. I am asking why i am getting harder to myself. It may not my fault? Our architecture doesn't spend enough time to explain complicated sides of project for us or i am not enough smart one for understand fastly. Our architecture also doesn't know what kind of hell he is creating ? Seeing 3 level generic types and 4-5 level generic inheritance in domain model objects hell makes me think so really. It looks abusing concepts more than reduce complexity. Thinking that he hasn't experienced before such a big project while he is getting confused in problems of the project. May i am not in right company ? May i am not good programmer ? May i am really stupid ? Become good in programming concepts is not enough to deal big project's complications so someone should to tell me that i have to still effort too much even i am good programmer for adopting myself to any big project ? Also i had another bad experiences from previous job but my professional experiences is almost few months but i spend 2 years for learning and coding for fun and i really can say that i have well skills on OOP, Design Patterns, coding standards and deep knowledge in language currently used. Sometimes i am thinking to leave programming professionally and work in any lame job while doing programming just for hobby. Waiting suggestions and insights

  • Is there a "golden ratio" in coding?

    - by badallen
    My coworkers and I often come up with silly ideas such as adding entries to Urban Dictionary that are inappropriate but completely make sense if you are a developer. Or making rap songs that are about delegates, reflections or closures in JS... Anyhow, here is what I brought up this afternoon which was immediately dismissed to be a stupid idea. So I want to see if I can get redemptions here. My idea is coming up with a Golden Ratio (or in the neighborhood of) between the number of classes per project versus the number of methods/functions per class versus the number of lines per method/function. I know this is silly and borderline, if not completely, useless, but just think of all the legacy methods or classes you have encountered that are absolutely horrid - like methods with 10000 lines or classes with 10000 methods. So Golden Ratio, anyone? :)

  • Partnering with a web designer to build and launch websites for fun. Where should I look for someone? [closed]

    - by FastCoder
    I have been working with web sites and web development for a long time and as a result I am able to build and launch complex websites (social network, dating site, stackoverflow, etc.) in little time (1-3 weeks). Problem is: I know very little about CSS, page layout, photoshop and graphic design. Of course I know HTML but when it comes to putting together something that looks good I am horrible. I just don't have the artistic skills. I wanted to launch some websites without any silly or naive intent to take over the world. Just for fun and to improve the portfolio. How do you guys recommend that I approach this problem of "finding this right partner" with the same mindset? Where should I look for this person? I have no idea... :(
