• Why do programmers seem to be such bad spellers?

  - by Joel Etherton

  Programming languages are very precise tools based on explicit grammars. They're very picky, and when being used they require an exacting amount of detail. C#, for instance, is case sensitive so even getting the case of an argument wrong will cause an error. Questions asked all over the StackExchange are replete with misspellings, grammatical errors, and other problems that seem to indicate a lack of attention to detail when it comes to the language itself. Now, I understand there are a lot of programmers out there whose native language is not English, and I am not directing this question (rant one might say) at them. I'm referring to the individuals who are clearly from an English speaking background who refuse to pay attention to these simple details. I am not perfect by any means, but I try to use the language correctly so that my meaning will be understood correctly. I find programmers misspelling variable names, classes, and all manner of words in any kind of technical documentation they might write. I have had to withstand code where I am repeatedly referring to the subit[sic] button or HttpWebResponse reponse. The general complaint about bad spelling is one thing, and it will always be there. I accept that. But my question/comment is about the proclivity of bad spelling within the programming community. I would think that people who deal with such exacting tools to be more naturally predisposed towards proper spelling. Yet this doesn't seem to be the case.

• Microsoft Silverlight Analytics Framework - Day 2 Part 2 of MIX 2010

  - by GeekAgilistMercenary

  I went to the session on Microsoft Silverlight Analytics Framework (MSAF) today while here at MIX 2010.  It was a great walk through the features, ideas, and what the end goal is.  Michael Scherotter did a great job of lining up the ideas, intentions, and the functional ideas behind the framework. The framework is built around the Silverlight Behaviors.  If you aren't sure what behaviors are, check out these entries from Nikhilk.net Silverlight Behaviors, Silverlight 3 Drag Behavior, An Introduction to Behaviors, Triggers, and Actions, and of course the MSDN Documentation on the matter. Some of the key features of the framework is to support out-of-browser scenarios, which works perfectly with out Webtrends DX Web Services.  Offline scenarios, which again, we have worked toward supporting at Webtrends DC Web Services via caching and other criteria as needed.  Another feature that I was really stoked about is the Microsoft Expression Blend integration that removes the need for coding, thus simplifying the addition of analytics components based on events or other actions within a Silverlight Application.  This framework also easily supports A/B Testing (again, something we do quit a bit of at Webtrends with Webtrends Optimize. The last thing I really wanted to point out was the control support that this framework has support in already from Telerik RadControls, Smooth Streaming Media Element, and Microsoft Silverlight Media Framework Player 1.0.  These are implemented with behaviors and handlers exposed via MEF (Managed Extensibility Framework). All in all, great second day, great analytics framework for Silverlight, and great presentation.  Until tomorrow, adieu. For this original entry and all sorts of other technical gibberish I write, check out my other blog Agilist Mercenary.

• Codifying a natural language requirements spec

  - by ProfK

  I have a fairly technical functionality requirements spec, expressed in English prose, produced by my project manager. It is structured as a collection of UI tabs, where the requirements for each tab are expressed as a lit of UI fields and a list of business rules for the tab. Most business rules are for UI fields on a tab, e.g: a) Must be alphanumeric, max length 20. b) Must be a dropdown, with values from table x. c) Is mandatory. d) Is mandatory under certain conditions, e.g. another field is just populated, or has a specific value. Then other business rules get a little more complex. The spec is for a job application, so the central business object (table) is the Applicant, and we have several other tables with one-to-many relationships with applicant, such as Degree, HighSchool, PreviousEmployer, Diploma, etc. e) One such complex rule says a status field can only be assigned a certain value if a many-side record exists in at least one of the many-side tables. E.g. the Applicant has at least one HighSchool or at least one Diploma record. I am looking for advice on how to codify these requirements into a more structured specification defined in terms of tables, fields, and relationships, especially for the conditional rules for fields and for the presence of related records. Any suggestions and advice will be most welcome, but I would be overjoyed if i could find an already defined system or structure for expressing things like this.

• How can dev teams prevent slow performance in consumer apps?

  - by Crashworks

  When I previously asked what's responsible for slow software, a few answers I've received suggested it was a social and management problem: This isn't a technical problem, it's a marketing and management problem.... Utimately, the product mangers are responsible to write the specs for what the user is supposed to get. Lots of things can go wrong: The product manager fails to put button response in the spec ... The QA folks do a mediocre job of testing against the spec ... if the product management and QA staff are all asleep at the wheel, we programmers can't make up for that. —Bob Murphy People work on good-size apps. As they work, performance problems creep in, just like bugs. The difference is - bugs are "bad" - they cry out "find me, and fix me". Performance problems just sit there and get worse. Programmers often think "Well, my code wouldn't have a performance problem. Rather, management needs to buy me a newer/bigger/faster machine." The fact is, if developers periodically just hunt for performance problems (which is actually very easy) they could simply clean them out. —Mike Dunlavey So, if this is a social problem, what social mechanisms can an organization put into place to avoid shipping slow software to its customers?

• 1and1: Unable to host an external domain

  - by Django Reinhardt

  I'm sorry if this isn't the right place for this question, but I'm presently having difficulties with my hosting provider (1and1). Two weeks ago, two of my clients bought hosting from them on my recommendation, but as it turned out, 1and1 are having severe technical difficulties. Right now non of their hosting packages are able to accept ANY external domains. So either you pay the costs of transferring the registrar of your domain, or you use the ugly 1and1 domain name. Not any good for a hosting company of 1and1's reputation! They have been promising me for two weeks that they're going to fix the problem, but as you have probably guessed by now, that hasn't been the case. I would like to know if a) Anyone else is in the same boat as me, and b) If there are other comparably reputable hosting providers that I should consider moving to instead? Very disappointing! :( Note: This is for 1and1 in the UK. I imagine it isn't affecting users in other countries(?) Clarification: 1and1 are unable to accept ANY external domains. That means that even if you update your DNS details on your domain, their system cannot be updated to add your external domain to your account.

• May In Review

  - by Richard Bingham

  Content Highlights Our Application Composer series had fresh articles on the related internal data model and lots more on Groovy, including how to manipulate your data and a useful table showing you when and where groovy scripting can be used. For those just getting started with Fusion Applications user security, this article gave some handy examples to get your going. Jani's Java Cloud Service series continued strongly, with examples of integration using ADFbc, a Web Service Proxy client, and the ADF Data Control. From Other Teams The Oracle A-Team provided a broad set of articles during May, with various topics related to Fusion Applications including patching and performance management for on-premises deployments, and generic content on both integration and data extraction via web services. As part of their presentation to Oracle Israel User Group, our AppsUX colleagues explained the fresh new type of interface to Oracle Sales, through the voice mobile apps. This was in addition to demonstrations of the newer Release 8 Simplified UI customization options. Finally Angelo, our colleague in Platform Technical Services, explained in his blog how to use the findCriteria element included in all Oracle Sales web services to reduce the data returned, making response payloads much more specific, lightweight and therefore usable. Events and Announcements Oliver explained in this post about the new set of code samples on OTN for extending Sales Cloud using Oracle Platform as a Service. In addition, a new set of cloud developer documentation was released to provide more guided-learning on extending Oracle Sales Cloud with Oracle Platform as a Service (PaaS) services. This illustrative content is mainly as downloadable PDFs, and include topics covering sales cloud extensibility basics, using web services from JDeveloper (including security), using PaaS for SaaS development, and ADF (including mobile).

• Speaking at MySQL Connect 2012

  - by jonathonc

  At the end of September, the MySQL Connect 2012 conference will be held as part of Oracle OpenWorld in San Francisco. MySQL Connect is a two day event that allows attendees to focus on MySQL at a technical depth with presentations and interaction with many of the MySQL developers, engineers and other knowledgeable staff. There is also a range a international speakers to give broader knowledge to the presentations. I am presenting a Hands-On Lab on Sunday 30th September 16:15 - 17:15 entitled HOL10474 - MySQL Security: Authentication and Auditing. The sessions goes through an introduction to the plugin API and how it can help expand the capabilities of MySQL. Since it is a hands-on lab, attendees will use practical examples of implementing simple plugins to get a start in developing their own plugins. These plugin examples are based around implementing PAM authentication and how it can be utilized to offer greater security for the MySQL Server. Once the authentication has been tested, a method to monitor it will be implemented using the auditing API and logging different events as they happen in the service. There is a total of 78 sessions at MySQL Connect 2012 with a great range of speakers. Hope to see you there!

• How to Be a Software Engineer?

  - by Mistrio

  My problem is kind of weird so please bear with me. I have been working in a start up concerned basically with mobile development since my graduation 2 years ago. I develop apps for iOS but it's not really relevant. The start up structure is simply founders developers, with no middle-tier technical supervision or project management whatsoever. A typical project cycle of ours is like this: meet with a client send very vague recruitment to an outsourced graphics designer dig in development right after we get the design, no questions asked then improvise improvise improvise! It's not that we are unaware that stuff like requirements analysis, UML, design patterns, source code control, testing, development methodologies... etc. exist, we just simply don't use them, and I mean like never. The result is usually a clunk of hardly-maintainable yet working code. Despite everything we are literally flourishing with many successful apps on all platforms and bigger clients each project. The thing is, we want the chaos and we're looking for advice. How would you fix our company technically? Given that you can't hire project managers or team leaders just because we are barely 5 developers, so it wouldn't be a justified cost for the founders, but one-time things like courses, books, private training... etc is an option. Lastly, if it's relevant, we are based in Egypt. Thank you a lot in advance.

• How to keep word document, html and pdf documentation aligned

  - by dendini

  Is there a way to write documentation in a WYSIWYG editor which can then export into HTML, WORD and PDF and keep copies synchronized? This documentation are mostly technical notes and some contextual help for some softwares so they must contain images and some styling, they are not programmer's documentation (API list or functions list) for which probably a program like Javadoc or Doxygen would be the best choice. For example how do companies with hundreds different software lines and thousands of programmers deal with this? I have several solutions but they all seem lacking in some aspect: Latex/Tex : very good pdf and html export, not very user friendly and no full-blown WYSIWYG editor available. LibreOffice/OpenOffice : full blown WYSIWYG editor however html export not so good (need to edit manually exported html which needs to be maintained separately ) Mediawiki or any other wiki : could be keeping documentation in wikitext format, so html is automatically generated, pdf exportation is quite good with many available plugins. Again however need some formation for the staff to use it and need to setup a server for this. Notice I'm not asking for software A vs software B, I'm asking for general advice, big companies procedures for documentation and yes some software product names if available.

• Reflector Pro has now been released!

  - by CliveT

  After moving into the .NET division in May , and having a great time working on Reflector, I'm pleased to say that the results of that work are now available. Reflector Pro has now been released! The old Reflector as you know and love it is still available free of charge, and as part of this project we've fixed a number of bugs in the de-compilation that have been around for a long time. The Pro version comes as an add-in for Visual Studio - this offers dynamic de-compilation and generation of pdb files which allow you to step into the de-compiled code. Alex has some good pictures of this functionality on his beta post from around a month ago. Thanks to the other guys who've worked on this for taking me along for the ride - Alex, Andrew, Bart and Jason. Stephen did some great usability work, Chris Alford did some great technical authoring and Laila handled the launch publicity. Like all projects, there's always more I'd like to have done, but what we have looks like a pretty powerful addition to the developer's set of tools to me. Please try it and give us feedback on the forum.

• IASA ITARC &ndash; Denver May 6th

  - by Jeff Certain

  The Denver chapter of the International Association of Software Architects (IASA) is holding an IT Architect Regional Conference (ITARC) in Denver on May 6th. The speaker list for this conference is amazing. Paul Rayner, Dave McComb, Randy Kahle, Peter Provost, Randy Stafford, George Fairbanks – all great speakers, and from Colorado. Brandon Satrom (who also happens to be the president of the IASA Austin chapter) will also be speaking, as will some other heavy hitters (for example, Ted Farrell, Chief Architect and Senior VP of Oracle). This is an amazing line-up, and the conference is quite reasonably priced ($150 for IASA members until April 10th, including a catered lunch). I also have the privilege of being a presenter at this conference. If you’ve ever heard any of the previously named speakers, you know that they set the bar quite high. Sounds like I’m going to have to step up my game. What I get to talk about is really cool stuff. The company I work for – Colorado CustomWare – brought me on board nearly two years ago. To say there was some technical debt is somewhat… understated. Equally understated would be that management is committed to doing the right thing. Over the past two years, we’ve done significant architectural refactoring – including an effort that took the entire team offline for most of a month. We’ve reduced the application size by 50% without losing functionality. As you can imagine, this has reduced the complexity of the application, making development faster and less prone to bugs. We’ve made many other changes – moving to an agile process, training developers, moving towards a more OO architecture. The changes we’ve made reveal, in some ways, just how far afield we were.. and there are still more changes to be made. Amazingly enough, our leadership team is eager for me to share these experiences with other architects. I’m really looking forward to being able to do so.

• Does a team of developers need a manager?

  - by Amadiere

  Background: I'm currently part of a team of four: 1 manager, 1 senior developer and 2 developers. We do a range of bespoke in-house systems / projects (e.g. 6-8 weeks) for an organisation of around 3500 staff, as well as all the maintenance and support required from the systems that have been created before. There is not enough of us to do all the work that is potentially coming our way - we're understaffed. Management acknowledge this, but budget restraints limit our ability to recruit additional members to the team (even if we make the salary back in savings). The Change This leaves us where we are now. Our manager is due to leave his role for pastures new, leaving a vacancy in the team. Management are using this opportunity to restructure our team which would see the team manager role replaced by another developer and another senior developer. Their logic being that we need more developers, so here's a way of funding it (one of the roles is partially funded from another vacant post). The team would have no direct line manager and the roles and responsibilities would be divided up between the seniors and the (relatively new to post) service manager (a non-technical role with little-to-no development knowledge/experience whose focus is shared amongst a number of other teams and individuals) - who would be our next actual manager up the food chain. I guess the final question is: Is it possible to run a development team without an manager? Have you had experience of this? And what things could go wrong / could be of benefit to us? I'd ideally like to "see the light" and the benefits of doing things this way, or come up with some points for argument against it.

• Which iPhone ad API has produced the highest revenue for you?

  - by Kyle Humfeld

  This isn't a technical question, but more of a request for advice and empirical/anecdotal data. I'm nearly done writing a free app for iPhone, and I'm at the stage where I'm going to put ads into the app. I've had mixed success in the past with iAd (their fill rates have been atrocious recently, and their payouts have cut by about 75% over the past 4 months or so), and would like to know how much ad revenue you, the community, has seen from the various ad APIs you've used for your iPhone apps. This isn't a request for opinion, i.e. which is 'better', only what kinds of numbers you're seeing. I don't need absolute figures, but 'iAd pays x% higher than AdMob, and y% lower than AdSense' would be extremely helpful to me as I make my decision as to which ad API to integrate into my App. Also, have you had any experience or success with integrating multiple ad APIs into the same app? That's something I'm considering doing in my current iAd-filled apps (particularly my iPad app, which has yet to receive a single impression after nearly 60,000 requests)... something like: 1) Request-from-iAd 2) if that fails, request-from-adSense 3) if that fails, request-from-adMob 4) if that fails, ... etc.

• Which iPhone ad API has produced the highest revenue for you?

• Flash AS3 sidescrolling tiles optimization

  - by Galvanize

  I'm trying to make a sidescrolling game in Flash that will run on a low performance laptop. While studying the subject from Tonypa I saw that he builds a Bitmap by making copys of the BitmapData of each tile from the Tile Sheet and placing it on the bigger Bitmat with the size of the screen. But when I came to think on how to scroll my map I ran into some optimization doubts. I came up with two choices: Create a MovieClip, place a Bitmap instance for each tile that is shown on the screen + 1 row in it, then move them all. Then when the tile ran off the screen I would move it to end of the MovieClip and replace their BitmapData for the next row in my map. Use a Bitmap with copys of each tile in it (as shown in Tonypa's tutorial) but 1 extra row, move the whole Bitmap, and when it comes the time to replace rows, redraw the whole Bitmap and move it back to the origin position. The first idea is how a co-worker of mine suggested, the second one is my own, but none of us has enough technical knowledge to be sure on a technique that would be optimal in performance, can anyone help?

• No "Choose OS" screen after co-installation of Ubuntu 12.04

  - by Léon McGregor

  I don't have any technical knowledge of Ubuntu but wanted to install it on a partition. Step-by-step of what i did. used disk management in windows 7 to clear 50gb of space used a usb live ubuntu 12.04 installer in custom install mode used the installer's built in disk manager to set up 2gb swap space and 48gb ext4 space ran installation, with option to copy over documents and settings from windows 7 restarted after completion. After this, my computer automatically loads ubuntu 12 and skips the option to load windows 7. i know the files are still there, as i can see them in the file manager. When trying to fix with the win7 installer dvd it tries to repair the OS in drive [D:] i.e. it recognises the disc itself as the OS and ignores the [c:] files. I think, after browsing around here, similar problems suggest this is a problem with the boot loader, but if the win7 dvd won't work, then i don't have any way to fix this. does anyone know of a way to force the computer to show a "choose OS" screen?

• Developing a Configurable Pricing Program

  - by Ben DeMott

  The organization I work at has some interesting requirements when it comes to pricing for online commerce. Currently the developers write different 'pricing rules' and those rules can be applied to our items based on attributes of the items. For Example: INPUTS: [cost, sug_retail, discontinued, warehouse_qty, orderable_qty, brand, type, days_available, shipping_rate, weight, map_protected, map_discount] MATCH: brand=x, warehouse_qty 1, discontinued=True, map_protected=False SET: retail_price = (sug_retail * 0.95), offer_price1 = (cost * 1.25 + shipping_rate) I am looking to allow the merchandising team to have more control over the pricing and formulas - they are afterall technical enough to write excel formulas. I've been looking at writing a desktop application that uses something like numexpr http://code.google.com/p/numexpr/ or http://sympy.org/en/index.html to allow non-programmers to integrate their own logic into our pricing backend. We have multiple price-tiers we have to set, for multiple markets, so an elegant solution is needed. It's getting frustrating for the dev team to continually tweak/manage all of the pricing rules (we sell over 200 brands in 3 markets). My question is; does this seem like a decent approach? Can you think of a better way to parse string-mathematical-grammer? Can you think of a different way for users to provide formula's to integrate into a automated pricing system? Does anyone know of any examples of existing applications that do this? Excel, and Access are out of the question - the volume of data we manipulate has already proven the need to automate it - now we just need some visibility into that automation.

• Burned CD-R are not identical to the input iso image, why?

  - by Grumbel

  I have the issue that sometimes when I burn an iso image to a CD-R with: sudo wodim -v driveropts=burnfree -data dev=/dev/scd0 input.iso And then read it back out again with: sudo dd if=/dev/cdrom of=output.iso dd: reading `/dev/cdrom': Input/output error ... That I end up with two iso images that are not identical, namely the output.iso is missing 2048 bytes at the end. When I however mount the iso image or CD-R and compare the actual files on the mountpoint, both are identical. Is that expected behavior or is that an actually incorrect burn of the data? And if its expected, how can I verify that the burn process was successful? The reason why I ask in the first place is that it seems to be reproducible behavior, certain iso images come out 2048 bytes short, even on repeated burns, but all burned CD-Rs are under themselves identical. Also what is the reason behind the: dd: reading `/dev/cdrom': Input/output error As it happens always, I assume it is normal, but what is the technical reason behind it? I assume CDs don't allow the device to detect the size directly, so dd reads till it encounters the end the hard way. Edit: User karol on superusers.com mentioned that both the size issue and the read error are the result of using -tao (default) in wodim instead of -dao mode. I couldn't yet test it, but it sounds like the most plausible explanation so far.

• Getting into game/game engine programming

  - by Darkslash

  So I am interested in learning game programming, but I really have an interest in the lower level engineering in games. I have openGL experience, and I am really interested in learning more about implementing AI, Physics, etc. I have a computer science degree, so I really like getting into technical stuff. Many times when I ask about this sort of thing, I get a lot of "Use an engine", "Use Unity3d", "Why waste your time writing code that already exists", etc etc. My idea was to use simpler libraries such as SFML or XNA so that I could learn how to implement the more complex systems. The thing is, although I do want to write games, I want to learn things that using something like Unity simply doesnt teach you. My goal is not to make a current generation quality 3D game to sell, I just want to make some cool smaller games and learn all I can about the programming side of game development. Is this something that people just do not do anymore? It seems like everywhere I turn people are using Unity or UDK or GameMaker. I fully understand why you would use a tool like these, but I cant see how they would suit my purposes. So where does someone like myself turn? Am I trying to learn something that people just do not bother doing anymore? Is the innovation in this area gone and just all about gameplay now? Im sorry if this question seems silly, but I am genuinely interested in knowing more about this and meeting more people who are interested in this sort of thing.
