  • TODO Formatting

    - by charlie.mott
    Article Source: http://geekswithblogs.net/charliemott TODO's should only be used for a short period of time to remind you that something needs to be done. They should then be addressed as soon as possible. In order to know who owns a TODO task and how long it’s been outstanding, my company uses the following standard for TODO formatting: Format:     // TODO : Owner Initials – Date Created – Description of task. Sample:     // TODO: CM – 2012/01/20 – Move this class to a new location so it can be reused. Using this pattern makes it easy to use the Resharper TODO explorer. The Carrot In order to make it easy for developers to apply this rule, a code snippet can be created in Visual Studio. Even better, I created a Resharper template. This gives the facility to use the current user name and current date macros. image This actually makes the formatting look like this. Sample:     // TODO: cmott – 2012/01/20 – Move this class to a new location so it can be reused. The Stick How to you enforce such a rule? I tried to create a custom Resharper Highlighting Pattern to perform custom code analysis inspection for deviations from this pattern. However, I did not have any success. The find dialog would not accept // text. If I work it out, I will update this blog post. StyleCop Instead I created a custom StyleCop rule. I followed the approach used with the StyleCop Contrib project. This provides a simple to use base class and easy to use unit testing framework. I will upload this todo format analyzer as a patch to that project. image

  • Logarithmic spacing of FFT subbands

    - by Mykel Stone
    I'm trying to do the examples within the GameDev.net Beat Detection article ( http://archive.gamedev.net/archive/reference/programming/features/beatdetection/index.html ) I have no issue with performing a FFT and getting the frequency data and doing most of the article. I'm running into trouble though in the section 2.B, Enhancements and beat decision factors. in this section the author gives 3 equations numbered R10-R12 to be used to determine how many bins go into each subband: R10 - Linear increase of the width of the subband with its index R11 - We can choose for example the width of the first subband R12 - The sum of all the widths must not exceed 1024 He says the following in the article: "Once you have equations (R11) and (R12) it is fairly easy to extract 'a' and 'b', and thus to find the law of the 'wi'. This calculus of 'a' and 'b' must be made manually and 'a' and 'b' defined as constants in the source; indeed they do not vary during the song." However, I cannot seem to understand how these values are calculated...I'm probably missing something simple, but learning fourier analysis in a couple of weeks has left me Decimated-in-Mind and I cannot seem to see it.

  • How to Set Up a MongoDB NoSQL Cluster Using Oracle Solaris Zones

    - by Orgad Kimchi
    This article starts with a brief overview of MongoDB and follows with an example of setting up a MongoDB three nodes cluster using Oracle Solaris Zones. The following are benefits of using Oracle Solaris for a MongoDB cluster: • You can add new MongoDB hosts to the cluster in minutes instead of hours using the zone cloning feature. Using Oracle Solaris Zones, you can easily scale out your MongoDB cluster. • In case there is a user error or software error, the Service Management Facility ensures the high availability of each cluster member and ensures that MongoDB replication failover will occur only as a last resort. • You can discover performance issues in minutes versus days by using DTrace, which provides increased operating system observability. DTrace provides a holistic performance overview of the operating system and allows deep performance analysis through cooperation with the built-in MongoDB tools. • ZFS built-in compression provides optimized disk I/O utilization for better I/O performance. In the example presented in this article, all the MongoDB cluster building blocks will be installed using the Oracle Solaris Zones, Service Management Facility, ZFS, and network virtualization technologies. Figure 1 shows the architecture:

  • How do I create my own programming language and a compiler for it

    - by Dave
    I am thorough with programming and have come across languages including BASIC, FORTRAN, COBOL, LISP, LOGO, Java, C++, C, MATLAB, Mathematica, Python, Ruby, Perl, Javascript, Assembly and so on. I can't understand how people create programming languages and devise compilers for it. I also couldn't understand how people create OS like Windows, Mac, UNIX, DOS and so on. The other thing that is mysterious to me is how people create libraries like OpenGL, OpenCL, OpenCV, Cocoa, MFC and so on. The last thing I am unable to figure out is how scientists devise an assembly language and an assembler for a microprocessor. I would really like to learn all of these stuff and I am 15 years old. I always wanted to be a computer scientist some one like Babbage, Turing, Shannon, or Dennis Ritchie. I have already read Aho's Compiler Design and Tanenbaum's OS concepts book and they all only discuss concepts and code in a high level. They don't go into the details and nuances and how to devise a compiler or operating system. I want a concrete understanding so that I can create one myself and not just an understanding of what a thread, semaphore, process, or parsing is. I asked my brother about all this. He is a SB student in EECS at MIT and hasn't got a clue of how to actually create all these stuff in the real world. All he knows is just an understanding of Compiler Design and OS concepts like the ones that you guys have mentioned (ie like Thread, Synchronisation, Concurrency, memory management, Lexical Analysis, Intermediate code generation and so on)

  • Need ideas for an innovation week

    - by slandau
    So 4 times a year we have an innovation week (to even out the odd sprint releases). This whole week is dedicated to experimenting with new technology/ideas that could potentially help progress the software department or the company as a whole, and serve as sort of a starting point for new ideas and brainstorming. For example, the last one contained a lot of projects. One was the re-design of our web app into more of a Web 2.0 look and feel using JQuery and a lot of cool CSS tricks. Another was a proposal for a new bug tracking software as opposed to the clearly outdated one we use, and another was a very cool JQuery/Js design that could show the same page to multiple users on different computers and allow each of them to take "charge" of the page, disabling the other one from doing anything, and vice versa, seeing all updates in real time -- sort of like Netmeeting through Js. Well, this is my first one as a new employee so I wanted to think of something cool. We get one week (anywhere from 40-60 hours or so), and we usually pair up or do this in groups of 3-4, depending on how many projects there are. Projects have to get approved but usually that doesn't prove to be too difficult. We are in the financial analysis software industry if the domain was leading you guys to think of anything helpful. I am primarily working on a web app in MVC 2 at the moment using a lot of JQuery and a C# backend. Do you guys have any idea of something that would be cool/beneficial/worth it?

  • How to document requirements for an API systematically?

    - by Heinrich
    I am currently working on a project, where I have to analyze the requirements of two given IT systems, that use cloud computing, for a Cloud API. In other words, I have to analyze what requirements these systems have for a Cloud API, such that they would be able to switch it, while being able to accomplish their current goals. Let me give you an example for some informal requirements of Project A: When starting virtual machines in the cloud through the API, it must be possible to specify the memory size, CPU type, operating system and a SSH key for the root user. It must be possible to monitor the inbound and outbound network traffic per hour per virtual machine. The API must support the assignment of public IPs to a virtual machine and the retrieval of the public IPs. ... In a later stage of the project I will analyze some Cloud Computing standards that standardize cloud APIs to find out where possible shortcomings in the current standards are. A finding could and will probably be, that a certain standard does not support monitoring resource usage and thus is not currently usable. I am currently trying to find a way to systematically write down and classify my requirements. I feel that the way I currently have them written down (like the three points above) is too informal. I have read in a couple of requirements enineering and software architecture books, but they all focus too much on details and implementation. I do really only care about the functionalities provided through the API/interface and I don't think UML diagrams etc. are the right choice for me. I think currently the requirements that I collected can be described as user stories, but is that already enough for a sophisticated requirements analysis? Probably I should go "one level deeper" ... Any advice/learning resources for me?

  • Is it better to specialize in a single field I like, or expand into other fields to broaden my horizons?

    - by Oak
    This is a dilemma about which I have been thinking for quite a while. I'm a graduate student and my topics of interest are programming language design, code analysis, compilation, etc. So far, this field has been very interesting and rewarding for me, so I was thinking about finding a job in that field and continuing to specialize in it. I feel like it's a relatively solid field which won't "get out of style" anytime soon. I've always thought that in such complex fields it's better to be a real expert than just another guy who superficially understand what the experts are talking about. On the other hand, I feel that by specializing this way I really limit my future option. I have always been a strong believer in multidisciplinary approaches to problems. Maybe I should go search for a general programming job in which I could gain experience in other fields, as well as occasionally apply my favorite field for solving problems. Specializing in only one or two fields can prevent me from thinking outside the box and cause stagnation. I would really like to hear more opinions about this choice. The truth is I'm already leaning towards one of the choices, so basic psychology says nothing will change my mind, but I would still love to hear some feedback.

  • Usual Suspects: Typical 3rd Party Entities in E-Commerce [closed]

    - by zharvey
    I am doing some requirements/analysis for a web app that I'd like to build (Ruby/Java developer here). This web app would have a store front, shopping cart and would need to be totally compliant with all e-com best practices. It's amazing how much non-technical info comes up when you search for phrases like "how does e-commerce work", but very little comes up in the way of technical details. As such, I'm having extreme frustration finding answers to what I consider pretty straight-forward questions. I came here because I believe this question is not off-topic; if it is, please leave a comment as to why this question does not belong here and I will happily remove it myself (upvotes if your comment can point me to the correct place for this question!). So then: What 3rd parties will I need to work with to have a modern, web-compliant e-com site? So far I can account for a payment gateway provider like Authorize.net and an SSL certificate provider like Trustwave. Any others? What other standards besides PCI compliance will I be held to (besides governing laws, of course!)? Vulnerability scans: PCI compliance requires quarterly scans: if I'm a "Level 4" (low volume) Merchant does that still apply to me? Irregardless, my backend architecture is quite huge, with web servers, app servers, database, message brokers and more. Do each of these servers need to be scanned?!? If not what servers do need to get these quarterly scans? I usually hate to ask micro-questions inside of one large one, but these are so closely-related I just felt like asking them all separately would be spamming the site with too many petty questions. Thanks in advance!

  • Leaving the field of programming. What are the options?

    - by hal10001
    A lot of graduates ask about getting into this field, but I know there are times when I (as well as many others) think about leaving, too. My issue is that I love solving problems and the act of creating something that people enjoy using, and that is what keeps bringing me back. Lately, though, programming has become less of the act of creation and about solving problems, and has become more about being "a monkey at a keyboard". Can you offer any advice with regard to: What fields would offer equivalent problem-solving challenges consistently? How you would go about doing the research, or considering the career change? Basically anything else you think would be helpful in this situation. EDIT: I guess I should clarify and say that I've been in the field about 10 years, and I have had my fair share of working environments. The place where I am at now, and even the previous two jobs, the people I worked with have been great. I've been very lucky in that respect. I'm beginning to wonder if the next step for me has little to do with actual programming and more to do with business analysis or strategic consulting. I would hate to get too much onto the business side of things though, as I like being around tech folks more.

  • How to distinguish doc, ppt, xls files, without looking at file extension

    - by Shelby. S
    So I was wondering how would you differentiate ppt, xls and doc files from each other in linux regardless of extensions. I tried 'file' but from the looks of it, all of MSOffice files are categorized under the same file type. Similarly I'm having trouble with docx, xlsx and pptx files, since they're essentially all zip files containing a bunch of xml. I also tried a python script importing the magic module, but no go. I'm trying to identify the actual file for a sandbox analysis. And for this specific purpose I need to find the actual file type in order to run it in the sandbox vm (the Windows vm runs everything by extension). Let's say my sample file is labeled as try.exe, but in reality it's just a doc file. My script will rename it as try.exe.doc, which would work fine for doc files. But since linux identifies all MSOffice files as simple DOC files then there's no way to identify ppt or xls files. As a result the sandbox wont' analyze the sample correctly.

  • TechEd North America 2012–Day 3 #msTechEd #teched

    - by Marco Russo (SQLBI)
    Yesterday I spent the longest day at this TechEd: we talked with many people at Community Night until 9pm and I have to say that just a few months after Analysis Services 2012 has been released, there are many people already using it. And the adoption of PowerPivot is starting to be quite large. Many new ideas and challenging coming from several different real world scenarios. I was tired but really happy. Alberto presented his Many-to-Many Relationships in BISM Tabular session that was in the same time slot of the BI Power Hour. For this reason, very few people attended Alberto’s session so I think many will watch the recorded session (it should be available within a few days). So what about today? I’ll spend some time at Technical Learning Center area (full schedule here) but the most important event today will be the Querying multi-billion rows with many to many relationships in SSAS Tabular (xVelocity) at the Private Cloud, Public Cloud and Data Platform Theater in the Technical Learning Center area (next to the SQL Server 2012 zone).  Why you should attend? Mainly because you will see live demo over 4 billion rows table with many-to-many relationships involved in complex queries. But for those of you that think this is not enough to attend a 15 minute funny session, well, we’ll give away some 8GB USB Memory Keys to those of you that will guess exact response time of queries before execution. Convinced? Join us at 11:15am and don’t be late, the session will finish at 11:30am! After that, we’ll run a book signing session at the Bookstore at 12:30pm and I will be in the Technical Learning Center area at 3:00pm until 5:00pm. See you there!

  • Is there a canonical source supporting "all-surrogates"?

    - by user61852
    Background The "all-PK-must-be-surrogates" approach is not present in Codd's Relational Model or any SQL Standard (ANSI, ISO or other). Canonical books seems to elude this restrictions too. Oracle's own data dictionary scheme uses natural keys in some tables and surrogate keys in other tables. I mention this because these people must know a thing or two about RDBMS design. PPDM (Professional Petroleum Data Management Association) recommend the same canonical books do: Use surrogate keys as primary keys when: There are no natural or business keys Natural or business keys are bad ( change often ) The value of natural or business key is not known at the time of inserting record Multicolumn natural keys ( usually several FK ) exceed three columns, which makes joins too verbose. Also I have not found canonical source that says natural keys need to be immutable. All I find is that they need to be very estable, i.e need to be changed only in very rare ocassions, if ever. I mention PPDM because these people must know a thing or two about RDBMS design too. The origins of the "all-surrogates" approach seems to come from recommendations from some ORM frameworks. It's true that the approach allows for rapid database modeling by not having to do much business analysis, but at the expense of maintainability and readability of the SQL code. Much prevision is made for something that may or may not happen in the future ( the natural PK changed so we will have to use the RDBMS cascade update funtionality ) at the expense of day-to-day task like having to join more tables in every query and having to write code for importing data between databases, an otherwise very strightfoward procedure (due to the need to avoid PK colisions and having to create stage/equivalence tables beforehand ). Other argument is that indexes based on integers are faster, but that has to be supported with benchmarks. Obviously, long, varying varchars are not good for PK. But indexes based on short, fix-length varchar are almost as fast as integers. The questions - Is there any canonical source that supports the "all-PK-must-be-surrogates" approach ? - Has Codd's relational model been superceded by a newer relational model ?

  • Is there any simple game that involves psychological factors?

    - by Roman
    I need to find a simple game in which several people need to interact with each other. The game should be simple for an analysis (it should be simple to describe what happens in the game, what players did). Because of the last reason, the video games are not appropriate for my purposes. I am thinking of a simple, schematic, strategic game where people can make a limited set of simple moves. Moreover, the moves of the game should be conditioned not only by a pure logic (like in chess or go). The behavior in the game should depend on psychological factors, on relations between people. In more details, I think it should be a cooperation game where people make their decisions based on mutual trust. It would be nice if players can express punishment and forgiveness in the game. Does anybody knows a game that is close to what I have described above? ADDED I need to add that I need a game where actions of players are simple and easy to formalize. Because of that I cannot use verbal games (where communication between players is important). By simple actions I understand, for example, moves on the board from one position to another one, or passing chips from one player to another one and so on.

  • Advice on choosing a book to read

    - by Kioshiki
    I would like to ask for some recommendations on useful books to read. Initially I had intended on posting quite a long description of my current issue and asking for advice. But I realised that I didn’t have a clear idea of what I wanted to ask. One thing that is clear to me is that my knowledge in various areas needs improving and reading is one method of doing that. Though choosing the right book to read seems like a task in itself when there are so many books out there. I am a programmer but I also deal with analysis, design & testing. So I am not sure what type of book to read. One option might be to work through two books at the same time. I had thought maybe one about design or practices and another of a more technical focus. Recently I came across one book that I thought might be useful to read: http://xunitpatterns.com/index.html It seems like an interesting book, but the comments I read on amazon.co.uk show that the book is probably longer than it needs to be. Has anyone read it and can comment on this? Another book that I already own and would probably be a good one to finish reading is this: http://www.amazon.co.uk/Code-Complete-Practical-Handbook-Construction/dp/0735619670/ref=sr_1_1?ie=UTF8&qid=1309438553&sr=8-1 Has anyone else read this who can comment on its usefulness? Beyond these two I currently have no clear idea of what to read. I have thought about reading a book related to OO design or the GOF design patterns. But I wonder if I am worrying too much about the process and practices and not focusing on the actual work. I would be very grateful for any suggestions or comments. Many Thanks, Kioshiki

  • The Talent Behind Customer Experience

    - by Christina McKeon
    Earlier, I wrote about Powerful Data Lessons from the Presidential Election. A key component of the Obama team’s data analysis deserves its own discussion—the people. Recruiters are probably scrambling to find out who those Obama data crunchers are and lure them into corporations. For the Obama team, these data scientists became a secret ingredient that the competition didn’t have. This team of analysts knew how to hear the signal and ignore the noise, how to segment and target its base, and how to model scenarios and revise plans based on what the data told them. The talent was the difference. As you work to transform your organization to be more customer-centric, don’t forget that talent is a critical element. Journey mapping is a good start to understanding how your talent impacts your customer experiences. Part of journey mapping includes documenting the “on-stage” and “back-stage” systems and touchpoints. When mapping this part of your customers’ journey, include the roles and talent behind the employee actions—both customer facing and further upstream from that customer touchpoint. Know what each of these roles does, how well you are retaining people in these areas, and your plans to fill these open positions in the future. To use data scientists as an example, this job will be in high demand over the next 10 years. The workforce is shrinking, and higher education institutions may not be able to turn out trained data scientists as fast as you need them. You don’t want to be caught with a skills deficit, so consider how you can best plan for the future talent you will need. Have your existing employees make their career aspirations known to you now. You may find you already have employees willing to take on roles that drive better customer experiences. Then develop customer experience talent from within your organization through targeted learning programs. If you know that you will need to go outside the organization, build those candidate relationships now. Nurture the candidates you want to hire and partner with universities, colleges, and trade associations so you can increase the number of qualified candidates in your talent pool.

  • Beginners guide to developing optimization software

    - by Florenc
    I am novice in "serious" programming i.e. applications that deal with real-life applications and software projects that go beyond school assignments. My interests include optimization, operations research, algorithms and lately i discovered how much I do like software design/development/engineering. I have already developed some simple desktop applications for some "famous" problems like TSP using heuristc approaches, a VRP solver (in progress) and so on. While developing this kind of software I actually used basic concepts taught at school such as object-orientation analysis and design. But, I found these courses rather elementary and quite boring (for my expectations). So I decided to go a little further and start developing "real" software (and this is where I realized how important and interesting software engineering/design is.) Now, here's my issue: I can not find a "study guide" for developing software of this kind. Currently, there are numerous resources out there (books, websites, tutorials) in designing and developing complex IS, web applications, smartphone apps but I can't find a book for example entitled "optimization software development". Definetly, someone could claim that "design patterns apply to software in general" but that's not my point. My point is that I could simply use my imagination for "simple" implementations, but what happens, when my imagination can not go further? In other words I'm looking for a guide/path to bridge the gap between: Mathematics-Algorithm Design-Software Engineering-Optimization-Software development

  • Toolset agnostic build server and Silverlight projects

    - by Marko Apfel
    Problem Normally I try to have my continuous integration as most a possible toolset free to ensure that no local stuff could have an impact to my build. My Silverlight app references a special compile target in a folder outside my developer tree: <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" /> So I copied the stuff from this folder to a local one and changed the call to this target in my csproj: <Import Project="..\..\..\tools\WebApplications\Microsoft.WebApplication.targets" /> And now Visual Studio Conversion Wizard welcomes my with this: Solution Regardless of which line I write – this conversion comes back again and again, if the line has another form than <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" /> So it seems that there is no simple way to change this behaviour. Workaraound I must accept, that this line must be in the csproj and to run the build the toolset must be copied to the build server at the correct location. So go to your development machine where Visual Studio is installed and copy the folder “C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications” to your build server at the equivalent location.   Xmas wishes to Microsoft: Please provide technologies to let us developers bundle all needed stuff for a project in one developer tree. It should be possible that one checkout starts us up! No additional installations regardless whether it is a developing machine or dedicated build or continuous integration server. Silverlight is only one example, code analysis configurations could also be terrible and much more …

  • Should I listen to my employer and use CASE tools?

    - by omsharp
    My employer (Not a Developer) thinks that CASE tools will help us improve our development process and documentation. I am not sure about that, we are a small team of 5 developers building mobile banking solutions for local clients. I think CASE tools will be a waste of time and money as they need to be purchased and we will need some time before we get used to them and be efficient working with them for modeling and stuff. Code generation is another issue, I really think that the CASE generated code won't be as good as code written by good developers. I think that if we stick with agile princeliness, design patterns, use TDD, and keep our code clean. we should be good. And as far as Analysis and Design, I think simple UML diagrams on whiteboard should do the trick. Documentation is good and important, but should be made as little as possible and we should not focus on Docs and forget the code. This is what i think. Am I correct? or should I listen to my employer and start researching for an appropriate CASE Tool?

  • Microsoft is Top Pick for ALM

    - by Arkham
    Investigating the market for a new software product can be a daunting task. Sometimes it’s difficult to even uncover all of the players. There’s no shortage of rhetoric on each vendor’s web site, but how can today’s CTO get objective information about how a software package ranks against it’s peers in a given space? Every year, Gartner releases what they call a Magic Quadrant report evaluating various products in a given space. This past week, Gartner released their analysis of products in the Application Lifecycle Management (ALM) arena. It is very exciting to see us in the top spot as a thought leader and for our ability to execute. If you are interested in ALM, you can read through an entire reprint of the report here. There’s plenty of new competitors listed and some of the existing competitors have shifted quite a bit. And this comes prior to the release of Team Foundation Server 2012! I suppose with all of the new features in 2012, they could just add another square to the upper-right. It’s beyond awesome! It’s be-awesome!

  • Assuming "clean code/architecture" is there a difference in "effort" between PHP or Java/J2EE web application development?

    - by PhD
    A client asked us to estimate effort when selecting PHP as the implementation language for his next web-based application. We spent about a week exploring PHP, prototyping, testing etc., We are quite new to this language - may have hacked around it in the past but, let's go with PHP-noobs but application development experts (for the lack of a better, less flattering word :) It seems, that if we write, clean maintainable code, follow separation of concerns, enterprise architecture patters (DAOs etc.) the 'effort' in creating an object-oriented PHP based web-application seems to be the same for a Java based one. Here's our equation for estimating the effort (development/delivery time): ConstructionEffort = f(analysis, design, coding, testing, review, deployment) We were specifically comparing effort estimates in creating an enterprise application with the following: PHP + CakePHP/CodeIgniter (should we have considered others?) Java + Spring + Restlet It's an end-to-end application: Client: Javascript/jQuery + HTML/CSS Middle tier/Business Logic - (Still evaluating PHP/Java) Database: MySQL The effort estimates of the 1st and 3rd tier are constant and relatively independent of the middle tier's technology. At a high level with an initial breakdown into user stories of the requested features as well as a high-level SWAG on the sheer number of classes/SLOC that would be required for PHP doesn't seem to differ by much from what is required of the same in Java. Is this correct? We are basing our initial estimates on the initial prototyping/coding we've done with PHP - we are currently disregarding fluency with the language as a factor, since that'll be an initial hurdle and not a long term impediment IMHO (we also have sufficient time to become quite fluent with PHP). I'm interested in knowing the programmers' perspective with respect to effort when creating similar applications with either of the languages to justify choosing one over the other. Are we missing something here? It seems we are going against popular belief of PHP being quicker to market (or we being very fluent with Java have our vision clouded). It doesn't seem to have any coding/programming effort saving from what we/ve played around with.
