• Using template questions in a technical interview

  - by Desolate Planet

  I've recently been in an argument with a colleage about technical questions in interviews. As a graduate, I went round lots of companies and noticed they used the same questions. An example is "Can you write a function that determines if a number is prime or not?", 4 years later, I find that particular question is quite common even for a junior developer. I might not be looking at this the correct way, but shouldn't software houses be intelligent enought to think up their own interview questions. This may well be the case, but I've been to about 16 interviews as a graduate and the same questions came up in about 75% of them. This leads me to believe that many companies are lazy and simply Google: 'Template questions for interviewing software developers' and I kind of look down on that. Question: Is it better to use a sest of questions off some template or should software houses strive to be more original and come up with their own interview material? From my point of view, if I failed an inteview and went off and looked for good answers to the questions I messed up on, I could fly through the next interview if they questions are the same.

• Which language meets my needs? [closed]

  - by Gerald Goward

  I am a junior C# developer, working for half a year now. In my company I am working on some enterprise projects and after doing it for quite some time I understood that I dont like enterprise projects. I have my own browser-game written in PHP+MySql with some simple HTML+CSS and I have 300 active (those, who entered the game at least once per 5 days) players currently :) After thinking quite some time I understood that I am interested in: 1). Web-development AND 2). standalone programs (but not enterprise ones). 3). Development for mobile platforms is also nice, Android/iOs. 1st and 2nd categories are what I want the most. Android/iOs is good too. I am NOT interested in big systems which are hard to integrate, I am not interested in enterprise systems. In future I would like to start my own business/projects. I would like to create my own projects or/and create a small programmers company to create and release own products. Please tell me what programming language(s)/technologies would you advice me for it? Thanks alot! UPD: It's NOT a "which language is better" or any flame/holywar generating topic since I ask for language that suits my EXACT needs better. I believe C++ is better for low-level coding, while PHP is good for web-development and Object-C being made for iOs. I am still newbie at programming so dont hate me please.

• What are the common mistakes in 'tailored Scrum approaches'?

  - by Clark Gable

  I have seen this before. Management wants to be agile and be scrummified, but does not want to step out of the status quo. My latest observation is no different; here, the Scrum is 'tailored' to the organization; specifically into a weird many-people-process. The diagram showing the different participants. I am putting together a document listing why this will not work. Here are the obvious ones: 1. There are product owner agents (an obvious WTF), who report to the product owner: causing dilution of decision making capability 2. There is a role that looks similar to a manager in the traditional approach - development manager: an obvious attempt at command-and-control model 3. The ScrumMaster's role includes collecting timesheets, which are used to track progress instead of burndown charts: detrimental to agile's efforts to build teams with motivated individuals Leaving the question "how would you convince the management?", my question is more at, "what else do you see as failures in this/similar 'tailored Scrum approaches'? EDIT: The diagram might use a few more details 1. The development manager is not part of the development team, with not very clearly defined responsibilities, except: developer performance assessemnt, recruitment, etc., 2. There are more than two teams (with ScrumMaster+development manager+dev team) with the same product owner for all teams!

• Working Abroad Advice Needed

  - by RBA

  Hi, First of all, Happy New Year everybody! I wish you for 2011 all the best! For several years I was thinking about to work abroad, and I want to make this step(to work in a/several foreign countries, for several years). I am a Software Developer with a Bachelor of Engineering in Computer Science, with a +4 years of experience in Delphi(and small working experience in other programming languages). Until now I've applied at aprox. 100 positions over the world, and I've been contacted by 4-5 hiring managers. Our technical discussions went good, but then we reached at working visa 'problem'. I don't have legal/health problems, but I don't poses a working permit in other countries except Romania. I've been reading several forums concerning the working visas (here I take out working visa for US or other 'hard to get visa' countries), and there are several steps which companies must do (so I can take out the bureaucracy problem) to make the papers. Concerning the cost of a visa, this goes up to one medium salary from that country(in most of the cases). I've been working for the last years with different clients, from a wide variety of countries, and I don't believe I will have problems with integration in a foreign country So, the problem is that the market don't need Delphi Developers (there is a small amount of open positions on the recruiting sites), and I should start learning other programming language(all the time is better to know other programming languages - but to master it, requires some time) with a higher market 'rank' (Java/C#/etc), OR the problem is only concerning the working visa, and maybe the reticence of the employer to foreign possible candidates? I'm asking this especially for those users who made this step in their life or they want to make it in the future. Best regards,

• Can you add doubleclick macros to exisiting ads

  - by picus

  Setup: A few weeks back I made some very simple html5 "ads" to run on a few of our partner sites. They weren't paid ads as we also manage these sites, however there are a few of them, so I made a modular solution that is hosted on one of our web servers and included on each page via javascript which outputs an iframe. Each search (ad has a search box) or click appends a url param that we track using custom vars in Google Analytics. In essence, the ad is a HTML page served in an iframe via javscript. Problem: We have an opportunity to run these ads on a third party site, I had sent them a brief how-to for inserting them and they came back saying that: The creative code doesn't contain the %u macro. We can’t substitute the default click-through URL without it. I am somewhat familiar with doubleclick from a web developer's POV, i have inserted DC dart tags before and even have implemented the ad tool for publishers. I have not, however, actually ever created an ad for the doubleclick network before. I assume the publisher needs these tags to track clicks and hence charge us. However, they have not responded to me in regards to these questions. Are macros something I can just add to or replace the existing links with, or do I need to completely setup the ad with doubleclcik - a big issue in the short term given we do not have a advertiser's account set up with them. Thanks in advance

• Dynamic libraries are not allowed on iOS but what about this?

  - by tapirath

  I'm currently using LuaJIT and its FFI interface to call C functions from LUA scripts. What FFI does is to look at dynamic libraries' exported symbols and let the developer use it directly form LUA. Kind of like Python ctypes. Obviously using dynamic libraries is not permitted in iOS for security reasons. So in order to come up with a solution I found the following snippet. /* (c) 2012 +++ Filip Stoklas, aka FipS, http://www.4FipS.com +++ THIS CODE IS FREE - LICENSED UNDER THE MIT LICENSE ARTICLE URL: http://forums.4fips.com/viewtopic.php?f=3&t=589 */ extern "C" { #include <lua.h> #include <lualib.h> #include <lauxlib.h> } // extern "C" #include <cassert> // Please note that despite the fact that we build this code as a regular // executable (exe), we still use __declspec(dllexport) to export // symbols. Without doing that FFI wouldn't be able to locate them! extern "C" __declspec(dllexport) void __cdecl hello_from_lua(const char *msg) { printf("A message from LUA: %s\n", msg); } const char *lua_code = "local ffi = require('ffi') \n" "ffi.cdef[[ \n" "const char * hello_from_lua(const char *); \n" // matches the C prototype "]] \n" "ffi.C.hello_from_lua('Hello from LUA!') \n" // do actual C call ; int main() { lua_State *lua = luaL_newstate(); assert(lua); luaL_openlibs(lua); const int status = luaL_dostring(lua, lua_code); if(status) printf("Couldn't execute LUA code: %s\n", lua_tostring(lua, -1)); lua_close(lua); return 0; } // output: // A message from LUA: Hello from LUA! Basically, instead of using a dynamic library, the symbols are exported directly inside the executable file. The question is: is this permitted by Apple? Thanks.

• so, my Cassandra consultant left me and now I'm thinking about reverting to mysql

  - by sathia

  I run a middle size community and some time ago I started to develop social capabilities such as follow, status update, wall etc. For some reason i thought that Cassandra was the right tool for the job so I looked online for a Cassandra developer and I found a very talented one. Unluckily in the midst of the development the dev left (too much jobs) and so I'm here with a very nice class, a very nice demo, but a lot of fears that I won't be able to handle basic things such as compaction, scaling etc. My biggest fear is to go online with all this coolness and then having a site inaccessible for hours or days. The mysql consultant (very talented too) keeps saying me that I should stick with Mysql which I know rather well and in case something's wrong we can manage. In that case I should take the class made for cassandra and abstract it for Mysql. My question is this: Should I find another dev/consultant and stick with Cassandra because for social things it is definitely the best tool for the job, or should I listen to the Mysql consultant and revert to Mysql?

• MySQL - Configuration

  - by Stuart Brierley

  Having previously detailed how to install MySQL Server, the next step is configuring MySQL. The MySQL configuration wizard can either be run immediately following installation from the MySQL installation wizard or manually from the Start Menu. Following the splash screen you can then choose whether to run a detailed or standard configuration. The detailed configuration allows you to create the optimal configuration for your specific machine, whereas the standard configuration creates a general configuration that can then be manually tuned. I chose detailed.   You are then asked to choose the type of server instance that is being configured. In this case it is a developer machine. Following this you are asked to choose the type of database usage that you expect on the server. I opted for multifunctional. You must then specify the location of the InnoDB tablespace.   Next specify the number of concurent connections to the server.   Now you must configure the networking options. I left the Strict mode enabled as this is the recommended option, but I disabled TCP/IP networking as I wanted to restrict this MySQL installation to the local machine only.   Set the character set that is best suited to your use - for me this was the default standard character set. Next up is the option to run MySQL as a service and whether or not to include the mysql dircetories in the windows PATH. I kept the install as a windows service option enabled, but unchecked the Launch MySQL server automatically option. This is because I only wanted MySQL running when I specifically want to use it. I also enabled the include in windows PATH option.   You can then change the security settings for the mysql installation. I opted to change the root password, disable root from local machines and disable annoymous access.   You are now ready to execute the configuration.   Once completed you should hopefully see the completed screen with lots of nice ticks against the various configuration tasks.

• Distributed Development Tools -- (Version control and Project Management)

  - by Macy Abbey

  I've recently become responsible for choosing which source control and project management software to use for a company that employs me. Currently it uses Jira (project management) and Subversion (version control). I know there are many other options out there -- the ones I know about are all in this article http://mashable.com/2010/07/14/distributed-developer-teams/ . I'm leaning towards recommending they just stay with what they have as it seems workable and any change would have to be worth the cost of switching to say github/basecamp or some other solution. Some details on the team: It's a distributed development shop. Meetings of the whole team in one room are rare. It's currently a very small development team (three developers). The project management software is used by developers and a product manager or two. What are you experiences with version control and project management web applications? Are there any you would recommend and you think are worth the switching cost of time to learn new services / implementing the change? Edit: After educating myself further on the options it appears DVCS offer powerful benefits that may be worth investing in now as opposed to later in the company's lifetime when the switching cost is higher: I'm a Subversion geek, why I should consider or not consider Mercurial or Git or any other DVCS?

• Advantages of relational databases over VSAM, ISAM and hierarchical data stores

  - by llaszews

  When migrating companies from legacy environments to the cloud, invariably you run into older hierarchical, flat file, VSAM, ISAM and other legacy data stores. There are many advantages to moving these databases into a relational database structure. The most important which is that most cloud providers run on relational database models. AWS, for example, supports Oracle, SQL Server, and MySQL. The top three 'other reasons' for moving to a relational database are: 1. Data Access – Thousands of database access tools from query creation to business intelligence. 2. Management and monitoring – Hundreds of tools for management and monitoring of the database. 3. Leverage all the free tools from relational database vendors. Free Oracle database tools include: -Application Express – WYSIWIG browse based application development and deployment. -SQL Developer – SQL and PL/SQL development. Database object maintenance. What is interesting is that Big Data NoSQL databases and XML databases are taking us back to the days of VSAM (key value databases) with NoSQL and IMS (hierarchical) with XML databases?

• Distinguishing between UI command & domain commands

  - by SonOfPirate

  I am building a WPF client application using the MVVM pattern that provides an interface on top of an existing set of business logic residing in a library which is shared with other applications. The business library followed a domain-driven architecture using CQRS to separate the read and write models (no event sourcing). The combination of technologies and patterns has brought up an interesting conundrum: The MVVM pattern uses the command pattern for handling user-interaction with the view models. .NET provides an ICommand interface which is implemented by most MVVM frameworks, like MVVM Light's RelayCommand and Prism's DelegateCommand. For example, the view model would expose a number of command objects as properties that are bound to the UI and respond when the user performs actions like clicking buttons. Many implementations of the CQRS use the command pattern to isolate and encapsulate individual behaviors. In my business library, we have implemented the write model as command / command-handler pairs. As such, when we want to do some work, such as create a new order, we 'issue' a command (CreateOrderCommand) which is routed to the command-handler responsible for executing the command. This is great, clearly explained in many sources and I am good with it. However, take this scenario: I have a ToolbarViewModel which exposes a CreateNewOrderCommand property. This ICommand object is bound to a button in the UI. When clicked, the UI command creates and issues a new CreateOrderCommand object to the domain which is handled by the CreateOrderCommandHandler. This is difficult to explain to other developers and I am finding myself getting tongue-tied because everything is a command. I'm sure I'm not the first developer to have patterns overlap like this where the naming/terminology also overlap. How have you approached distinguishing your commands used in the UI from those used in the domain? (Edit: I should mention that the business library is UI-agnostic, i.e. no UI technology-specific code exists, or will exists, in this library.)

• KISS principle applied to programming language design?

  - by Giorgio

  KISS ("keep it simple stupid", see e.g. here) is an important principle in software development, even though it apparently originated in engineering. Citing from the wikipedia article: The principle is best exemplified by the story of Johnson handing a team of design engineers a handful of tools, with the challenge that the jet aircraft they were designing must be repairable by an average mechanic in the field under combat conditions with only these tools. Hence, the 'stupid' refers to the relationship between the way things break and the sophistication available to fix them. If I wanted to apply this to the field of software development I would replace "jet aircraft" with "piece of software", "average mechanic" with "average developer" and "under combat conditions" with "under the expected software development / maintenance conditions" (deadlines, time constraints, meetings / interruptions, available tools, and so on). So it is a commonly accepted idea that one should try to keep a piece of software simple stupid so that it easy to work on it later. But can the KISS principle be applied also to programming language design? Do you know of any programming languages that have been designed specifically with this principle in mind, i.e. to "allow an average programmer under average working conditions to write and maintain as much code as possible with the least cognitive effort"? If you cite any specific language it would be great if you could add a link to some document in which this intent is clearly expressed by the language designers. In any case, I would be interested to learn about the designers' (documented) intentions rather than your personal opinion about a particular programming language.

• Book Review&ndash;Getting Started With OAuth 2.0

  - by Lori Lalonde

  Getting Started With OAuth 2.0, by Ryan Boyd, provides an introduction to the latest version of the OAuth protocol. The author starts off by exploring the origins of OAuth, along with its importance, and why developers should care about it. The bulk of this book involves a discussion of the various authorization flows that developers will need to consider when developing applications that will incorporate OAuth to manage user access and authorization. The author explains in detail which flow is appropriate to use based on the application being developed, as well as how to implement each type with step-by-step examples. Note that the examples in the book are focused on the Google and Facebook APIs. Personally, I would have liked to see some examples with the Twitter API as well. In addition to that, the author also discusses security considerations, error handling (what is returned if the access request fails), and access tokens (when are access tokens refreshed, and how access can be revoked). This book provides a good starting point for those developers looking to understand what OAuth is and how they can leverage it within their own applications. The book wraps up with a list of tools and libraries that are available to further assist the developer in exploring the APIs supporting the OAuth specification. I highly recommend this book as a must-read for developers at all levels that have not yet been exposed to OAuth. The eBook format of this book was provided free through O'Reilly's Blogger Review program.

• Acceptable placement of the composition root using dependency injection and inversion of control containers

  - by Lumirris

  I've read in several sources including Mark Seemann's 'Ploeh' blog about how the appropriate placement of the composition root of an IoC container is as close as possible to the entry point of an application. In the .NET world, these applications seem to be commonly thought of as Web projects, WPF projects, console applications, things with a typical UI (read: not library projects). Is it really going against this sage advice to place the composition root at the entry point of a library project, when it represents the logical entry point of a group of library projects, and the client of a project group such as this is someone else's work, whose author can't or won't add the composition root to their project (a UI project or yet another library project, even)? I'm familiar with Ninject as an IoC container implementation, but I imagine many others work the same way in that they can scan for a module containing all the necessary binding configurations. This means I could put a binding module in its own library project to compile with my main library project's output, and if the client wanted to change the configuration (an unlikely scenario in my case), they could drop in a replacement dll to replace the library with the binding module. This seems to avoid the most common clients having to deal with dependency injection and composition roots at all, and would make for the cleanest API for the library project group. Yet this seems to fly in the face of conventional wisdom on the issue. Is it just that most of the advice out there makes the assumption that the developer has some coordination with the development of the UI project(s) as well, rather than my case, in which I'm just developing libraries for others to use?

• Implicit OAuth2 endpoint vs. cookies

  - by Jamie

  I currently have an app which basically runs two halves of an API - a restful API for the web app, and a synchronisation API for the native clients (all over SSL). The web app is completely javascript based and is quite similar to the native clients anyway - except it currently does not work offline. What I'm hoping to do is merge the fragmented APIs into a single restful API. The web app currently authenticates by issuing a cookie to the client whereas the native clients work using a custom HMAC access token implementation. Obviously a public/private key scenario for a javascript app is a little pointless. I think the best solution would be to create an OAuth2 endpoint on the API (like Instagram, for example http://instagram.com/developer/authentication/) which is used by both the native apps and the web app. My question is, in terms of security how does an implicit OAuth2 flow compare (storing the access token in local storage) to "secure" cookies? Presumably although SSL solves man in the middle attacks, the user could theoretically grab the access token from local storage and copy it to another machine?

• Is it common for a development position to be extremely mundane and not challenging at all? [closed]

  - by Kim Jong Woo

  Hi guys so I am working at this company as a web developer but after 1 week of working here, I realize the stuff I am doing seem to be very easy stuff compared to what my peers who have been around for longer are doing. I am way ahead of my schedule and finish my projects early but it's because the work is not at all hard or problem solving involved. So I am puzzled why I would be thanked over doing such menial tasks. Is this normal? This is driving me nuts, I ask to be given more work and I do get it and still finish it quickly and accurately. Now I am having this paranoia that they are just conspiring to use me for a short period of time and terminate me. Am I going too far with this? I keep losing sleep over this. On days when I have a full load of work to complete, this uneasiness goes away but so far I feel like I am not being allowed to pursue what I thought I would do like solving and designing solutions. A lot of it doesn't require any thinking, just cleaning up other people's code and closing bug tickets.

  Visual studio 2010 is a great tool and i have become fan of visual studio 2010. I have found two new code profile in visual studio 2010. Web Development Profile Web Development Code Optimized Profile. Web Development profile will hide the top bar which contains the client object and and event dropdowns. So it will have more spaces. Another one web development code optimized which will hide all the things except main windows. It will hide Toolbox,CSS properties and all other things so you will have more spaces to play with your html. So as a web developer you can use this two great new profile as per your convenience when you only want to play with your html then use webdevelopement code  optimized profile and another interesting thing is that you don’t have to reset your settings you can also just do with Tools->Settings menu like below. This will swap different profile like below. Hope this will help you.. Technorati Tags: Visual Studio 2010,ASP.NET 4.0

• Is my concept in open source license correct?

  - by tester

  I would like to justify whether my concept in the open source license is correct, as you know that, misunderstanding the terms may lead to a serious law sue. Thank you. The main difference among the open source license is whether the license is copyleft. Copyleft license means allow the others to reproduce, modify and distribute the products but the released product is bound by the same licensing restriction. That means they have to use the same license for the modified version. Also, the copyleft license require all the released modified version to be free software. On the other hand, if any others create derived work incorporating non-copyleft licensed code, they can choose any license for the code. The serveral kinds of license and comparsion GPL is a restrictive license. Software requires to released as GPL license if that integrate or is modified from the other GPL license software . The library used in developing GPL license software are also restricted to GPL and LGPL , proprietary software are not allowed to employ (or complied with) in any part of the GPL application. LGPL is similar to GPL , but was more permissive with regarding allow the using of other non-GPL software. BSD is relatively simple license, it allow developer to do anything on the original source code . The license holder do not hold any legal responsibilities for their released product. Apache license is evolved from the BSD license. The legal terms are improved and are written by legal professionals in a more modern way. It covers comprehensive intellectual property ownership and liability issues. Also, are there any popular license beside these? Thank you

• Web Hosting Checklist

  - by Chris

  Hello, I am a web developer that is starting to look into hosting his own website. I would like to showcase my programming skills (PHP, MySQl, C#, Wordpress). My knowledge of languages I am OK with but the actually hosting site is where my knowledge starts to get a little shaky. I know the basics (bandwidth, sub-domains, re-write rules) but I would love your input, to help me formulate a check list of certain web-hosting services that I should be on the look-out for. Also I was wondering if there were any reliable hosting providers who give you the option to host both c# code-behinds and PHP code. As I would like to have two versions of my site, one in C# and one in PHP the hope is that if I need to look for another job this website will help me show possible employers my server side knowledge. I hope this is enough info, I did some researching online but found a bunch of unless articles and I've always have had luck on the StackExchange sites. So hopefully you, can help me. Thanks alot.

• Planning milestones and time

  - by Ignas

  I was hired by a marketing company a year ago initially for link building / SEO stuff, but I'm actually a Web developer and took the job just in desperation to have one (I'm still quite young and just finished 2nd year of University). From the 3rd day my boss realised that I'm not into that stuff at all and since he had an idea of a web based app we started to plan it. I estimated that it shouldn't take me longer than two months to do it, but as I was making it we soon realised that we want to add more and more stuff to make it even better. So the development on my own lasted for about 4 months, but then it became an enterprise size app and we hired another programmer to work along me. The guy was awesome at what he did, but because I was assigned to be programmer/project manager I had to set up milestones with deadlines and we missed most of them, because most of the time it was too much work, and my lack of experience kept me setting really optimistic deadlines. We still kept adding features and had changed the architecture of the application twice. My boss is a great guy and he gets that when we add features it expands the time frame in which things should be done so he wasn't angry at me nor the other guy. But I was feeling bad (I still am) that I suck at planning. I gained loads of experience from the programming side, but I still lack the management/planning skills which make me go nuts. So over the last year I have dedicated probably about 8 months of work to this app (obviously my studies affected it) and we're launching as a closed beta this month. So my question is how do I get better at planning/managing a project, how do you estimate the times? What do you take into consideration when setting goals. I'm working alone again because the other guy moved from the city. But I'm sure we'll be hiring to help me maintain it so I need to get better at it. Any hints, points or anything on the topic are appreciated.
