• Branching and CI Builds with Agile

  - by Bob Horn

  We follow many agile processes, including automated tests, continuous integration, sprint reviews, etc... We're currently having a debate about how often we should branch release builds. We've been doing two-week sprints and trying to deploy to production at the end of each sprint. Some of us think we should be branching every sprint. Some of us think that's overkill. If a project encompasses three Visual Studio solutions, and we branch every sprint, then that's three branches, and three CI builds to create every two weeks. If we do this for six months, we'll end up with 36 branches and 36 CI builds. There is overhead involved in that. For those of us that think that branching every sprint is overkill, we don't have a very good alternative. On my last project, we deployed some solutions from the Main trunk. Yeah, that's not good, but it saved on some of the overhead. What's the right way to manage branching/releasing and CI builds, using agile, when we have such short (two-week) sprint cycles?

• What's up with all the updates? [closed]

  - by Bob Babb

  I use Ubuntu exclusively for my job, especially for the fact that everything works and I get the most out of my processor and memory, but you are killing me with updates! I just lost a very good opportunity from a client that installed Ubuntu but got tired of all the updates. I really can't argue the fact. In a matter of a day I had two software updates. Quote from customer: "It's sad that I come in at 6:00 in the morning to install updates from a LTS version, and then before I leave at the end of the day I have 19 new updates to install. At least Microsoft bundles them in controllable groups." Sadly I have to agree, guys you have to do something about this. Please!

• ArchBeat Link-o-Rama Top 10 for October 2012

  - by Bob Rhubart

  The Top 10 most popular items shared on the OTN ArchBeat Facebook Page for October 2012. OAM/OVD JVM Tuning | @FusionSecExpert Vinay from the Oracle Fusion Middleware Architecture Group (known as the A-Team) shares a process for analyzing and improving performance in Oracle Virtual Directory and Oracle Access Manager. SOA Galore: New Books for Technical Eyes Only Shake up up your technical skills with this trio of new technical books from community members covering SOA and BPM. Clustering ODI11g for High-Availability Part 1: Introduction and Architecture | Richard Yeardley "JEE agents can be deployed alongside, or instead of, standalone agents," says Rittman Meade's Richard Yeardley. "But there is one key advantage in using JEE agents and WebLogic – when you deploy JEE agents as part of a WebLogic cluster they can be configured together to form a high availability cluster." Learn more in Yeardley's extensive post. Solving Big Problems in Our 21st Century Information Society | Irving Wladawsky-Berger "I believe that the kind of extensive collaboration between the private sector, academia and government represented by the Internet revolution will be the way we will generally tackle big problems in the 21st century. Just as with the Internet, governments have a major role to play as the catalyst for many of the big projects that the private sector will then take forward and exploit. The need for high bandwidth, robust national broadband infrastructures is but one such example." -- Irving Wladawsky-Berger Eventually, 90% of tech budgets will be outside IT departments | ZDNet Another interesting post from ZDNet blogger Joe McKendrick about changing roles in IT. ADF Mobile - Login Functionality | Andrejus Baranovskis "The new ADF Mobile approach with native deployment is cool when you want to access phone functionality (camera, email, sms and etc.), also when you want to build mobile applications with advanced UI," reports Oracle ACE Director Andrejus Baranovskis.

ADF Mobile Custom Javascript — iFrame Injection | John Brunswick The ADF Mobile Framework provides a range of out of the box components to add within your AMX pages, according to John Brunswick. But what happens when "an out of the box component does not directly fulfill your development need? What options are available to extend your application interface?" John has an answer. Oracle Solaris 11.1 update focuses on database integration, cloud | Mark Fontecchio TechTarget editor Mark Fontecchio reports on the recent Oracle Solaris 11.1 release, with comments from IDC's Al Gillen. Architects Matter: Making sense of the people who make sense of enterprise IT Why do architects matter? Oracle Enterprise Architect Eric Stephens suggests that you ask yourself this question the next time you take the elevator to the Oracle offices on the 45th floor of the Willis Tower in Chicago, Illinois (or any other skyscraper, for that matter). If you had to take the stairs to get to those offices, who would you blame? "You get the picture," he says. "Architecture is essential for any necessarily complex structure, be it a building or an enterprise." (Read the article) Thought for the Day "I will contend that conceptual integrity is the most important consideration in system design. It is better to have a system omit certain anomalous features and improvements, but to reflect one set of design ideas, than to have one that contains many good but independent and uncoordinated ideas." — Frederick P.

• How should I generate and store the boundries of a cave?

  - by Bob Roberts

  I am making a small cave copter game (seriously, where did this type of game come from anyway) and I am trying to figure out how to make and store the procedural generated walls. I am thinking about creating the walls by randomly picking two points away from the center of the screen. They will be no closer than the height of helicopter and no further than the edge of the screen, weighted to prefer to go in the same direction as the point prior so I end up with stalactites and stalagmites and not just noise, at set intervals of distance. To store, perhaps parallel arrays/lists, one for distance from center to top screen and one for distance from center to bottom. Am I way off base with my thinking? I just want the cave to be varied and challenging, I just have never worked with generating data like this. Edit: Woah, I just realized that my idea would lead to a player being able to stay in the middle of the screen and win. That isn't right at all. So the very basis of how I was going to generate is wrong. Edit 2: I also realized I left out a very crucial point. Part of the mechanics of the game will let the player go backwards therefor the data structure should be continuous.

• Are XML Comments Necessary Documentation?

  - by Bob Horn

  I used to be a fan of requiring XML comments for documentation. I've since changed my mind for two main reasons: Like good code, methods should be self-explanatory. In practice, most XML comments are useless noise that provide no additional value. Many times we simply use GhostDoc to generate generic comments, and this is what I mean by useless noise: /// <summary> /// Gets or sets the unit of measure. /// </summary> /// <value> /// The unit of measure. /// </value> public string UnitOfMeasure { get; set; } To me, that's obvious. Having said that, if there were special instructions to include, then we should absolutely use XML comments. I like this excerpt from this article: Sometimes, you will need to write comments. But, it should be the exception not the rule. Comments should only be used when they are expressing something that cannot be expressed in code. If you want to write elegant code, strive to eliminate comments and instead write self-documenting code. Am I wrong to think we should only be using XML comments when the code isn't enough to explain itself on its own? I believe this is a good example where XML comments make pretty code look ugly. It takes a class like this... public class RawMaterialLabel : EntityBase { public long Id { get; set; } public string ManufacturerId { get; set; } public string PartNumber { get; set; } public string Quantity { get; set; } public string UnitOfMeasure { get; set; } public string LotNumber { get; set; } public string SublotNumber { get; set; } public int LabelSerialNumber { get; set; } public string PurchaseOrderNumber { get; set; } public string PurchaseOrderLineNumber { get; set; } public DateTime ManufacturingDate { get; set; } public string LastModifiedUser { get; set; } public DateTime LastModifiedTime { get; set; } public Binary VersionNumber { get; set; } public ICollection<LotEquipmentScan> LotEquipmentScans { get; private set; } } ... And turns it into this: /// <summary> /// Container for properties of a raw material label /// </summary> public class RawMaterialLabel : EntityBase { /// <summary> /// Gets or sets the id. /// </summary> /// <value> /// The id. /// </value> public long Id { get; set; } /// <summary> /// Gets or sets the manufacturer id. /// </summary> /// <value> /// The manufacturer id. /// </value> public string ManufacturerId { get; set; } /// <summary> /// Gets or sets the part number. /// </summary> /// <value> /// The part number. /// </value> public string PartNumber { get; set; } /// <summary> /// Gets or sets the quantity. /// </summary> /// <value> /// The quantity. /// </value> public string Quantity { get; set; } /// <summary> /// Gets or sets the unit of measure. /// </summary> /// <value> /// The unit of measure. /// </value> public string UnitOfMeasure { get; set; } /// <summary> /// Gets or sets the lot number. /// </summary> /// <value> /// The lot number. /// </value> public string LotNumber { get; set; } /// <summary> /// Gets or sets the sublot number. /// </summary> /// <value> /// The sublot number. /// </value> public string SublotNumber { get; set; } /// <summary> /// Gets or sets the label serial number. /// </summary> /// <value> /// The label serial number. /// </value> public int LabelSerialNumber { get; set; } /// <summary> /// Gets or sets the purchase order number. /// </summary> /// <value> /// The purchase order number. /// </value> public string PurchaseOrderNumber { get; set; } /// <summary> /// Gets or sets the purchase order line number. /// </summary> /// <value> /// The purchase order line number. /// </value> public string PurchaseOrderLineNumber { get; set; } /// <summary> /// Gets or sets the manufacturing date. /// </summary> /// <value> /// The manufacturing date. /// </value> public DateTime ManufacturingDate { get; set; } /// <summary> /// Gets or sets the last modified user. /// </summary> /// <value> /// The last modified user. /// </value> public string LastModifiedUser { get; set; } /// <summary> /// Gets or sets the last modified time. /// </summary> /// <value> /// The last modified time. /// </value> public DateTime LastModifiedTime { get; set; } /// <summary> /// Gets or sets the version number. /// </summary> /// <value> /// The version number. /// </value> public Binary VersionNumber { get; set; } /// <summary> /// Gets the lot equipment scans. /// </summary> /// <value> /// The lot equipment scans. /// </value> public ICollection<LotEquipmentScan> LotEquipmentScans { get; private set; } }

• SOA Galore: New Books for Technical Eyes Only

  - by Bob Rhubart

  In my part of the world the weather has taken its seasonal turn toward the kind of cold, damp, miserable stuff that offers a major motivation to stay indoors. While I plan on spending some of that indoor time working my way through the new 50th anniversary James Bond box set, I will also devote some time to improving my mind rather than my martini-mixing skills by catching up on my reading. If you're in a similar situation, you might want to spend some of your time  with these new technical books written by community members: Oracle SOA Suite 11g Administrator's Handbook by Ahmed Aboulnaga and Arun Pareek.

• HTML 5, Fluid Pages and Google Mobile Index

  - by Bob

  I am currently migrating my site to HTML5, at the same time designing pages so that they are "fluid" and are equally presentable for a mobile or a large screen. I took the fluid approach so as not to have to develop a separate application for mobile devices and I'm pleasantly surprised with the results that look equally as good on an iPhone as they do on a large screen. Then I went into the Google Webmaster Tools facility and became aware of the Google Mobile Index. I'm confused now as HTML5 doesn't seem to be supported by Google Mobile Indexing. Does this mean that when I go live with my new "pride and joy" HTML5 site on a mobile it won't appear on any Google searches as it's not in the Google Mobile Index?

• Should Site Title be Before or After Page Title?

  - by NickAldwin

  Apologies if this is a dupe. I tried searching, but didn't find anything specifically addressing this concern. When creating a large(ish) site, page titles usually reference both the site name and the current page name. However, it seems there are two main conventions: Bob's Awesome Site - Contact Page and Contact Page - Bob's Awesome Site I've looked around, and pages usually use one of the two variants above. Is there any reason to use one over the other? SEO/readability/usability/etc? I've thought about it, and have only come up with: Page first - Differentiates the tab when the browser is crowded with lots of tabs Site first - Immediately see the "parent" site, so to speak; more cohesive experience

The Pragmatic Architect: To Boldly Go Where No One Has Gone Before | Frank Buschmann "Many architects have technical knowledge that's both impressive and sound, which is indeed an inevitable basis for design success," says Frank Buschmann. "Yet, a lot of software projects fail or suffer due to severe challenges in their architecture. The key to mastery is how architects approach design, what they value, and where they focus their attention and work." As retail dies, whom will be the winners? | Peter Evans-Greenwood "The problem for many retailers is that how consumers shop has changed but the the retailers haven't adapted, " says Peter Evans-Greenwood. "Their sole virtue was to be the last step in a supply chain delivering somebody else's products to the consumer. However, being the last step in the supply chain is no longer a virtue when consumers skip across channels and can reach around the globe, no longer dependant on or limited to what they can find locally." Thought for the Day "Brains require stimulation. If you're locked into a pattern of work, work, and more work, your brain soon habituates - the same way that it lets you stop hearing a clock ticking. So, if you want to be more effective at work, you must, paradoxically, be less single-minded in your devotion to work. Anything you do—anything—that stimulates new segments of your brain will make you a more effective programmer or analyst. I promise, with a money-back guarantee." — Gerald M.

You cannot be both. To be a politician is to champion perception over reality. To be an engineer is to make perception subservient to reality. They are opposites. You can't do both simultaneously.

• Architects, Leadership, and Influence

  - by Bob Rhubart

  Technical expertise is a given for architects. In addition to solid development experience, extensive knowledge of technical trends, tools, standards, and methodolgies (not to mention business accumen) provides the foundation for the decisions the architect must make in the effort to get all the pieces to work together. But even superior technical chops can't overcome a lack of leadership. Leadership is about influence: the ability to effectively communicate — to sell your ideas and defend your decisions in a manner that affects the decisions of the people around you. Leadership and influence are especially important in situations in which the architect may not have the authority to simply tell people what to do. And even when the architect has that kind of authority, influential leadership can mean the difference between gaining real buy-in and support from colleagues and stakeholders, and settling for their grudging acceptance (or worse). Guess which outcome is likely to produce the best results. In a previous post I presented some examples of the kind of criticism that is leveled at architects, a great deal of which can be attributed to a lack of leadership and influence on the part of the targets of that criticism. So it was serendipitous that I recently ran across a post on the Harvard Business Review blog written by Chris Musselwhite and Tammie Plouffe. That post, When Your Influence Is Ineffective, includes this: [I]nfluence becomes ineffective when individuals become so focused on the desired outcome that they fail to fully consider the situation. While the influencer may still gain the short-term desired outcome, he or she can do long-term damage to personal effectiveness and the organization, as it creates an atmosphere of distrust where people stop listening, and the potential for innovation or progress is diminished. The need to "see the big picture" is a grossly reductive assesement of the architect's responsibilities — but that doesn't mean it's not true. That big picture perspective must encompass both the technological elements of the architecture and the elements responsible for implementing those technologies in compliance with the prescribed architecture. Technologies may be tempermental, but they don't have personalities or egos, and they are unlikely to carry a grudge — not yet, anyway (Hello, Skynet!).  Effective leadership and the ability to influence people can help to ensure that all the pieces fit and that they work together, today and tomorrow.

• Sharing an internet connection through the Ethernet port

  - by Bob Cunningham

  I have a small living room PC (Bohica, running fully-updated Ubuntu 10.10/Maverick) connected to my HDTV that I use for web browsing and media streaming. It connects via WiFi (wlan0) to my Fedora server (Snafu) that in turn connects to the internet. I use static addressing, and everything has been working fine. I just got a Blu-ray player, and I'd like to give it wired network access to the internet via Bohica's available wired ethernet port (eth0). So far, I haven't been to get eth0 and the network configured to get the Blu-ray player talking to the internet. Here's my wlan0 configuration: ip4 addr: 192.168.0.100 mask: /24 (255.255.255.0) gateway: 192.168.0.4 (fedora box) The Blu-ray player is set to an IP of 192.168.0.98/24, with the same gateway as above. I want eth0 set to an IP of 192.168.0.99/24, but when I do this using nm-connection-editor I lose internet access (the system tries to use eth0 as the default internet access interface). How do I get my blu-ray player to talk to the internet through Bohica, and do so without disrupting my current (working) network? Thanks. Edit: Here's the relevant output from nm-tool with the Blu-ray player connected: $ nm-tool NetworkManager Tool State: connected - Device: eth0 Type: Wired Driver: forcedeth State: disconnected Default: no HW Address: 90:FB:A6:2C:94:32 Capabilities: Carrier Detect: yes Speed: 100 Mb/s Wired Properties Carrier: on - Device: wlan0 [wlan0] Type: 802.11 WiFi Driver: ndiswrapper State: connected Default: yes HW Address: 00:26:5A:C0:D0:05 IPv4 Settings: Address: 192.168.0.100 Prefix: 24 (255.255.255.0) Gateway: 192.168.0.4
