• What should be included in risk management section of software's architecture documentation?

  - by Limbo Exile

  I am going to develop a Java application (a Spring Web application that will be used to extract data from various data sources) and I want to include risk management of the software in the architecture documentation. By risk management (I am not sure if this is the right name) I mean documenting possibilities of what can go wrong with the software and what to do in those cases. At first I tried to draft some lists, including things like database performance decrease, change of external components that the software interacts with, security breaches etc. But as I am not an experienced developer I cannot rely on those drafts, I don't think they are exhaustive. I searched web hoping to find something similar to the Joel Test or to find any other resource that will cite the most popular causes of problems that should be included and analyzed in risk management documentation, but I haven't found much. Finally, my question is: What should be included in risk management section of software's architecture documentation?

• Software requirements specification, please help!

  - by Nicholas Chow

  For a school project, I had to create a SRS for a "fictional" application. However they did not show us what it exactly entails, and were very vague with explanations. The SRS asked of us has to have at least 5 functional requirements, 5 non functional requirements and 1 constraint. Now I have tried my best to make one however I think there are still a lot of mistakes in it. Could you all please look at it and provide me with some feedback on which parts I can improve or just tell me which parts are plain out wrong and how to make it better? (The project has a maximum of 12 pages so it is a bit long, I will post it below. FR1 Registration of Organizer FR1 describes the registration of an Organizer on CrowdFundum FR1.1 The system shall display a registration form on the website. FR1.2 The system shall require a Name, Username, Document number passport/ID card, Address, Zip code, City, Email address, Telephone number, Bank account, Captcha code on the registration form when a user registers.

• DI and hypothetical readonly setters in C#

  - by Luis Ferrao

  Sometimes I would like to declare a property like this: public string Name { get; readonly set; } I am wondering if anyone sees a reason why such a syntax shouldn't exist. I believe that because it is a subset of "get; private set;", it could only make code more robust. My feeling is that such setters would be extremely DI friendly, but of course I'm more interested in hearing your opinions than my own, so what do you think? I am aware of 'public readonly' fields, but those are not interface friendly so I don't even consider them. That said, I don't mind if you bring them up into the discussion Edit I realize reading the comments that perhaps my idea is a little confusing. The ultimate purpose of this new syntax would be to have an automatic property syntax that specifies that the backing private field should be readonly. Basically declaring a property using my hypothetical syntax public string Name { get; readonly set; } would be interpreted by C# as: private readonly string name; public string Name { get { return this.name; } } And the reason I say this would be DI friendly is because when we rely heavily on constructor injection, I believe it is good practice to declare our constructor injected fields as readonly.

• Project development without experience

  - by Raven13

  I'm a web developer who is part of a three-man team that has been tasked with a rather large and complex development project. Other than some direction and impetus from management, we're pretty much on our own to develop the new website. None of us have any project management experience nor do my two coworkers seem like they would be interested in taking on that role, so I feel like it's up to me to implement some kind of structure to the development process in order to avoid issues down the road. My question is: what can I do as a developer without project managment experience to ensure that our project gets developed successfully and avoid the pitfalls of developing a project without a plan?

• Flash messages in ASP.NET MVC without sessions

  - by Fernando Correia

  I'm developing a web application for Windows Azure using ASP.NET MVC 4. I would like to enforce one restriction in the architecture: do not use Session. To achieve availability on Azure, and since there is no sticky sessions, I would need to store the session data in some central service, probably either SQL Azure or the Caching Service. I would rather avoid sessions on the SQL database to avoid the increased latency, and the caching service on Azure is very expensive for the ammount of memory offered. On the other hand, I would like to have the ability to easily pass Flash-style messages among redirects. TempData is the recommended way to do this, but by default it uses the session object. So I would like to know: Is there an alternative way to use TempData that doesn't require sessions or shared data between servers? Cookies perhaps? Is there a better alternative I'm overlooking?

• Displaying device contacts with an indication that the contact is registered to the app

  - by Prasanna Aarthi

  We are developing a mobile app that needs to pick up device contacts, display them and indicate if the contact has already registered with this app. We have our DB in the server and the app fetches data using web services. What will be the best approach to implement the above scenario taking performance into consideration. Option 1: Every time user opens the app,fetch the contacts and send the list of email addresses to the server, check with the registered email ids and return the list of registered users in the contact list. In this approach whenever user opens the particular page, he needs to wait for few seconds to load data, but the contacts will be the latest from the device. Option 2: First time when the user opens the app, fetch contacts ,send the entire list of contacts and save it in the DB, retrieve list of registered users in the contacts then save this to local DB. From now on, data will be fetched from local DB and displayed. When a new user registers in the app, again check with records in central DB and send list of new users who are in your contacts that have registered to your app. This list will be added to local DB. and the process continues. In this case the new contacts added by user will not be updated in the app but retrieval and display of records would be quick. What would be the correct approach? In case there is a better way of doing this, please let me know.

• Is there an easy way to type in common math symbols?

  - by srcspider

  Disclaimer: I'm sure someone is going to moan about easy-of-use, for the purpose of this question consider readability to be the only factor that matters So I found this site that converts to easting northing, it's not really important what that even means but here's how the piece of javascript looks. /** * Convert Ordnance Survey grid reference easting/northing coordinate to (OSGB36) latitude/longitude * * @param {OsGridRef} gridref - easting/northing to be converted to latitude/longitude * @returns {LatLonE} latitude/longitude (in OSGB36) of supplied grid reference */ OsGridRef.osGridToLatLong = function(gridref) { var E = gridref.easting; var N = gridref.northing; var a = 6377563.396, b = 6356256.909; // Airy 1830 major & minor semi-axes var F0 = 0.9996012717; // NatGrid scale factor on central meridian var f0 = 49*Math.PI/180, ?0 = -2*Math.PI/180; // NatGrid true origin var N0 = -100000, E0 = 400000; // northing & easting of true origin, metres var e2 = 1 - (b*b)/(a*a); // eccentricity squared var n = (a-b)/(a+b), n2 = n*n, n3 = n*n*n; // n, n², n³ var f=f0, M=0; do { f = (N-N0-M)/(a*F0) + f; var Ma = (1 + n + (5/4)*n2 + (5/4)*n3) * (f-f0); var Mb = (3*n + 3*n*n + (21/8)*n3) * Math.sin(f-f0) * Math.cos(f+f0); var Mc = ((15/8)*n2 + (15/8)*n3) * Math.sin(2*(f-f0)) * Math.cos(2*(f+f0)); var Md = (35/24)*n3 * Math.sin(3*(f-f0)) * Math.cos(3*(f+f0)); M = b * F0 * (Ma - Mb + Mc - Md); // meridional arc } while (N-N0-M >= 0.00001); // ie until < 0.01mm var cosf = Math.cos(f), sinf = Math.sin(f); var ? = a*F0/Math.sqrt(1-e2*sinf*sinf); // nu = transverse radius of curvature var ? = a*F0*(1-e2)/Math.pow(1-e2*sinf*sinf, 1.5); // rho = meridional radius of curvature var ?2 = ?/?-1; // eta = ? var tanf = Math.tan(f); var tan2f = tanf*tanf, tan4f = tan2f*tan2f, tan6f = tan4f*tan2f; var secf = 1/cosf; var ?3 = ?*?*?, ?5 = ?3*?*?, ?7 = ?5*?*?; var VII = tanf/(2*?*?); var VIII = tanf/(24*?*?3)*(5+3*tan2f+?2-9*tan2f*?2); var IX = tanf/(720*?*?5)*(61+90*tan2f+45*tan4f); var X = secf/?; var XI = secf/(6*?3)*(?/?+2*tan2f); var XII = secf/(120*?5)*(5+28*tan2f+24*tan4f); var XIIA = secf/(5040*?7)*(61+662*tan2f+1320*tan4f+720*tan6f); var dE = (E-E0), dE2 = dE*dE, dE3 = dE2*dE, dE4 = dE2*dE2, dE5 = dE3*dE2, dE6 = dE4*dE2, dE7 = dE5*dE2; f = f - VII*dE2 + VIII*dE4 - IX*dE6; var ? = ?0 + X*dE - XI*dE3 + XII*dE5 - XIIA*dE7; return new LatLonE(f.toDegrees(), ?.toDegrees(), GeoParams.datum.OSGB36); } I found that to be a really nice way of writing an algorythm, at least as far as redability is concerned. Is there any way to easily write the special symbols. And by easily write I mean NOT copy/paste them.

• Is creating a full application in Silverlight advisable?

  - by Anthony

  Is creating a huge public site fully in Silverlight really advisable? for eg. an ecommerce site. I don't want to start any debate but actually I feel Silverlight shouldn't be used for full website because the biggest loss you incur is of SEO. No search engines till today can parse the xap file and index it based on it's content. You can get around it by doing ifs and thens like if Silverlight is not supported then make an Asp.Net equivalent page for it but that only doubles our effort of making application, more than anything else. Why write double code in 2 applications meant for the same purpose. If that is the only option why not create Asp.Net application only. What are your views? Thanks in advance :)

• How to translate formulas into form of natural language?

  - by Ricky

  I am recently working on a project aiming at evaluating whether an android app crashes or not. The evaluation process is 1.Collect the logs(which record the execution process of an app). 2.Generate formulas to predict the result (formulas is generated by GP) 3.Evaluate the logs by formulas Now I can produce formulas, but for convenience for users, I want to translate formulas into form of natural language and tell users why crash happened.(I think it looks like "inverse natural language processing".) To explain the idea more clearly, imagine you got a formula like this: 155 - count(onKeyDown) >= 148 It's obvious that if count(onKeyDown) 7, the result of "155 - count(onKeyDown) = 148" is false, so the log contains more than 7 onKeyDown event would be predicted "Failed". I want to show users that if onKeyDown event appears more than 7 times(155-148=7), this app will crash. However, the real formula is much more complicated, such as: (< !( ( SUM( {Att[17]}, Event[5]) <= MAX( {Att[7]}, Att[0] >= Att[11]) OR SUM( {Att[17]}, Event[5]) > MIN( {Att[12]}, 734 > Att[19]) ) OR count(Event[5]) != 1 ) > (< count(Att[4] = Att[3]) >= count(702 != Att[8]) + 348 / SUM( {Att[13]}, 641 < Att[12]) mod 587 - SUM( {Att[13]}, Att[10] < Att[15]) mod MAX( {Att[13]}, Event[2]) + 384 > count(Event[10]) != 1)) I tried to implement this function by C++, but it's quite difficult, here's the snippet of code I am working right now. Does anyone knows how to implement this function quickly?(maybe by some tools or research findings?)Any idea is welcomed: ) Thanks in advance.

• TDD vs. Productivity

  - by Nairou

  In my current project (a game, in C++), I decided that I would use Test Driven Development 100% during development. In terms of code quality, this has been great. My code has never been so well designed or so bug-free. I don't cringe when viewing code I wrote a year ago at the start of the project, and I have gained a much better sense for how to structure things, not only to be more easily testable, but to be simpler to implement and use. However... it has been a year since I started the project. Granted, I can only work on it in my spare time, but TDD is still slowing me down considerably compared to what I'm used to. I read that the slower development speed gets better over time, and I definitely do think up tests a lot more easily than I used to, but I've been at it for a year now and I'm still working at a snail's pace. Each time I think about the next step that needs work, I have to stop every time and think about how I would write a test for it, to allow me to write the actual code. I'll sometimes get stuck for hours, knowing exactly what code I want to write, but not knowing how to break it down finely enough to fully cover it with tests. Other times, I'll quickly think up a dozen tests, and spend an hour writing tests to cover a tiny piece of real code that would have otherwise taken a few minutes to write. Or, after finishing the 50th test to cover a particular entity in the game and all aspects of it's creation and usage, I look at my to-do list and see the next entity to be coded, and cringe in horror at the thought of writing another 50 similar tests to get it implemented. It's gotten to the point that, looking over the progress of the last year, I'm considering abandoning TDD for the sake of "getting the damn project finished". However, giving up the code quality that came with it is not something I'm looking forward to. I'm afraid that if I stop writing tests, then I'll slip out of the habit of making the code so modular and testable. Am I perhaps doing something wrong to still be so slow at this? Are there alternatives that speed up productivity without completely losing the benefits? TAD? Less test coverage? How do other people survive TDD without killing all productivity and motivation?

• Junior software developer - How to understand web aplications in depth?

  - by nat_gr

  I am currently a junior developer in web applications and specifically in asp.net mvc technology. My problem is that the c# senior developer in the company has no experience with this technology and I try to learn without any guidance. I went through all tutorials (e.g music store), codeplex projects and also read pro asp.net mvc 4. However, most of the examples are about crud and e-commerce applications. What I don't understand is how dependency injection fits in web applications (I have realized that is not only used for facilitating unit testing) or when i should use a custom model binder or how to model the business logic when there is already a database schema in place. I read the forum quite often and it would very helpful if some experienced developers could give me an insight about how to proceed. Do I need to read some books to understand the overall idea behind web applications? And what kind of application should I start building myself - I don't think it would be useful to create similar examples with the tutorials.

• Why is an anemic domain model considered bad in C#/OOP, but very important in F#/FP?

  - by Danny Tuppeny

  In a blog post on F# for fun and profit, it says: In a functional design, it is very important to separate behavior from data. The data types are simple and "dumb". And then separately, you have a number of functions that act on those data types. This is the exact opposite of an object-oriented design, where behavior and data are meant to be combined. After all, that's exactly what a class is. In a truly object-oriented design in fact, you should have nothing but behavior -- the data is private and can only be accessed via methods. In fact, in OOD, not having enough behavior around a data type is considered a Bad Thing, and even has a name: the "anemic domain model". Given that in C# we seem to keep borrowing from F#, and trying to write more functional-style code; how come we're not borrowing the idea of separating data/behavior, and even consider it bad? Is it simply that the definition doesn't with with OOP, or is there a concrete reason that it's bad in C# that for some reason doesn't apply in F# (and in fact, is reversed)? (Note: I'm specifically interested in the differences in C#/F# that could change the opinion of what is good/bad, rather than individuals that may disagree with either opinion in the blog post).

• Architecture for a template-building, WYSIWIG application

  - by Sam Selikoff

  I'm building a WYSIWYG designer in Ember.js. The designer will allow users to create campaigns - think MailChimp. To build a campaign, users will choose an existing template. The template will have a defined layout. The user will then be taken to the designer, where he will be able to edit the text and style, and additionally change some layout options. I've been thinking about how best to go about structuring this app, and there are a few hurdles. Specifically, the output of the campaign will be dynamic: eventually, it will be published somewhere, and when the consumers (not my users, but the people clicking on the campaign that my user created) visit the campaign, certain pieces of data will change, depending on the type of consumer viewing the campaign. That means the ultimate output of the designer will be a dynamic site. The data that is dynamic for this site - the end product - will not be manipulated by the user in the designer. However, the data that will be manipulated by the user in the designer are things like copy, styles, layout options, etc. I'll call the first set of variables server-side data, and the second client-side data. It seems, then, that the process will go something like this: I'll need to create templates for this designer that have two dynamic segments. For instance, the server-side data could be Liquid expressions, and the client-side data Handlebars expressions. When the user creates a campaign, I would compile the template on the back end using some dummy data for the server-side variables, and serve up a handlebars template to the Ember app. The user would then edit the template, and the Ember app would save all his edits to the JS variables that were powering the template. This way he'd be able to preview the template. When he saves, he'll send back the selected template, along with all the data and options he's made. When it comes time to publish, the back-end system will have to do two things: compile the template with Handlebars using the campaign data, and then compile the template with Liquid using the server-side data Is my thinking roughly accurate about this, or is there a simpler way?

• How important is knowing functionality before coding?

  - by minusSeven

  I work for a software development company where the development work have been off shored to us. The on shore team handle the support and talk directly to the clients. We never talk to the clients directly we just talk people from the on shore team who talk directly to the clients. When requirements come, on shore team talk to the clients and make requirement documents and informs us. We make design documents after studying the requirements (we follow traditional waterfall model ). But there is one problem in the whole process: nobody in the either off-shore or on-shore understand the functionality of the application completely. We just know its a big complex web app handling complex order processing, catalog management, campaign management and other activities. We struggle with the design document as the requirements would not be clear. It then goes into a series of questions/answers back and forth between the on shore team,off shore team and clients. We would often be told to understand functionality from the code. But that's usually not feasible as the code base is huge and even understanding a simple menu item take days if not weeks. We tried telling the clients to give us knowledge transfer about the application but to no avail. Our manager would often tell us to start coding even if the design document is not complete or requirements not clear. We would start by coding part of the requirement that seems clear and wait for the rest. This usually would delay the deployment by a month. In extreme cases we would have very low errors in the development and production but the clients would say that's not what they asked. That would start a blame game and a series of change requests and we would end up developing something very different. My question is how would you do development work if you don't know the functionality of the app fully? UPDATE About development methodology it isn't really my choice and I am not my team's lead It is the way it began. I tried to tell people about the advantages of agile but to no avail. Besides I don't think my team has the necessary mindset to work in AGILE environment.

• perl comparing 2 data file as array 2D for finding match one to one [migrated]

  - by roman serpa

  I'm doing a program that uses combinations of variables ( combiData.txt 63 rows x different number of columns) for analysing a data table ( j1j2_1.csv, 1000filas x 19 columns ) , to choose how many times each combination is repeated in data table and which rows come from (for instance, tableData[row][4]).

• Improving without mentor

  - by speeder

  Although I consider myself not much experienced, I keep landing in jobs as the leader somehow (in the current one I am tech director of the company, in a previous one I was the R&D head). I understand why this happen (I have a certain specific set of skills, and I use some uncommon programming languages), my issue is: I cannot find a mentor... I know there must be stuff to me learn, and I notice as I work over the years that I am slowly learning more and more, but I believe that there are some way to get better much faster than just coding... So, how I improve when there are no other person in the company to teach me, or to me read their code? (or fix their code even...) I think I am beyond books, but way below a "master" level, so I don't know where to learn more.

• How do you manage the testing of your Android software on physical devices?

  - by Philip Regan

  I'm in charge of managing mobile application development at my company, and I am currently building a mobile device "library" for testing. Essentially, we want to have a representative device in-house for each of the OSes we are developing for, currently iOS (iPhone-only), Blackberry, and Android. Simulators only go so far, but I'm placing into the process a step to test software on the devices themselves. The problem we're finding is with Android. I don't think any of us here ever really understood just how fragmented the whole platform is until we started looking at devices to acquire. We are going to wait until v2.3 of Android is released, but which products to choose? Do we go by the most popular by market share? Do we get a small range of products by specs from least to most powerful overall? We're trying to avoid having to manage a dozen different devices to test each app, if not because of cost if only for the repeated time sink. How do you manage the testing of your Android software on physical devices?

• How do I go about hosting facebook apps that are picking speed?

  - by Karthik

  My situation is this. I coded in php and built a facebook app. After 3 days it has 13,000 users. I have my own server at hostmonster. It is a regular plan costing me about $70 per year. It has unlimited bandwidth. I did not anticipate hosting apps or that it could pick up so many users. Already 1 Gb of data was transferred in the last few days. I am planning to build a few more apps(around 10 - 20) and reach atleast a million users in total. Should I continue hosting on the same server or move to a VPS? I am a student and I don't have too much of a disposable income. So I want to move only if it is necessary. Right now it shows 1 Gb/infinity in data transfer. Any help/suggestions highly appreciated.

• How to depict Import a file action in the Sequence diagram

  - by user970696

  Everyone says sequence diagrams are so easy but I just cannot figure this out. Basically user clicks on an 'Import from temp folder' button, the program opens a window with a list populated with filenames, user clicks on a filename, clicks on OK and the document is imported. I know the order of the actions but how to depict e.g. populating a list, or selecting an item from a list? So I assume the objects would be like: [USER] [ImportDialogWindow] [ListOfFiles:STRING] [?where to go with selected file]

• Card deck and sparse matrix interview questions

  - by MrDatabase

  I just had a technical phone screen w/ a start-up. Here's the technical questions I was asked ... and my answers. What do think of these answers? Feel free to post better answers :-) Question 1: how would you represent a standard 52 card deck in (basically any language)? How would you shuffle the deck? Answer: use an array containing a "Card" struct or class. Each instance of card has some unique identifier... either it's position in the array or a unique integer member variable in the range [0, 51]. Shuffle the cards by traversing the array once from index zero to index 51. Randomly swap ith card with "another card" (I didn't remember how this shuffle algorithm works exactly). Watch out for using the same probability for each card... that's a gotcha in this algorithm. I mentioned the algorithm is from Programming Pearls. Question 2: how to represent a large sparse matrix? the matrix can be very large... like 1000x1000... but only a relatively small number (~20) of the entries are non-zero. Answer: condense the array into a list of the non-zero entries. for a given entry (i,j) in the array... "map" (i,j) to a single integer k... then use k as a key into a dictionary or hashtable. For the 1000x1000 sparse array map (i,j) to k using something like f(i, j) = i + j * 1001. 1001 is just one plus the maximum of all i and j. I didn't recall exactly how this mapping worked... but the interviewer got the idea (I think). Are these good answers? I'm wondering because after I finished the second question the interviewer said the dreaded "well that's all the questions I have for now." Cheers!

• What should my "code sample" look like?

  - by thesunneversets

  I've just had quite a good phone interview (for a CakePHP-related position, not that it's especially important to the question). The interviewer seemed to be impressed with my resume and personality. At the end, though, he asked me to email him a code sample from my existing work project, "to check you're not secretly a terrible programmer, ha ha!" I'm not too worried that my code can't stand on its own two feet, but I'm very much an intermediate programmer rather than an expert. What obvious pitfalls should I make sure my code sample doesn't fall into, in case they rule me out on the spot? Secondly, and this is probably the harder part of the question to answer, what features in a code sample would be so impressive that they would instantly make you much more favourably inclined towards the programmer? All ideas or suggestions welcomed!

• What is the most effective way to add functionality to unfamiliar, structurally unsound code?

  - by Coder

  This is probably something everyone has to face during the development sooner or later. You have an existing code written by someone else, and you have to extend it to work under new requirements. Sometimes it's simple, but sometimes the modules have medium to high coupling and medium to low cohesion, so the moment you start touching anything, everything breaks. And you don't feel that it's fixed correctly when you get the new and old scenarios working again. One approach would be to write tests, but in reality, in all cases I've seen, that was pretty much impossible (reliance on GUI, missing specifications, threading, complex dependencies and hierarchies, deadlines, etc). So everything sort of falls back to good ol' cowboy coding approach. But I refuse to believe there is no other systematic way that would make everything easier. Does anyone know a better approach, or the name of the methodology that should be used in such cases?

• What makes a good developer / system documentation?

  - by deamon

  Much time is wasted to get new developers started with existing software systems, because there is no good documenation. But what makes a system documentation good? One thing is a good API documentation like the Java API doc, but how to transfer the "bigger picture" and other things that cannot be placed in the API doc? One constraint is that it should not be to hard and time consuming to write the docs, because that is one reason why it is omitted so often. So, what makes documentation good?

• Two internships at the same time -- good or bad?

  - by Karl

  I had no internship a few months ago, so I basically went on a 'resume mailing' spree and emailed a lot of companies that I was interested in working for and that had my line of work. This didn't prove futile until a company accepted me into their internship program but said that I would be working remotely. I had no problem with that, the project was good and I was interested. Now I have another internship at a company that is close to my home and I don't want to miss it at all! I can manage both internships side-by-side. In the day, I will do the internship that is closer to my home and at night (and other times), I can manage the remote internship. My question is -- should I both? I am particularly interested in how two internships at the same time are viewed. Would it look good or bad? PS: Neither is paying me anything, so money is not a factor.
