  • How do you dive into large code bases?

    - by miku
    What tools and techniques do you use for exploring and learning an unknown code base? I am thinking of tools like grep, ctags, unit-tests, functional test, class-diagram generators, call graphs, code metrics like sloccount and so on. I'd be interested in your experiences, the helpers you used or wrote yourself and the size of the codebase, with which you worked with. I realize, that this is also a process (happening over time) and that learning can mean "can give a ten minute intro" to "can refactor and shrink this to 30% of the size". Let's leave that open for now.

  • What are your advice, methods, or practices to take out the most from a day on-site at a customer?

    - by Stephane
    We just deployed a large software that affects the way the user work-day looks like in many aspects. It changes a lot of things in the way they interact between eachothers. The developers of the team are taking rounds and spending one day at the customer's site to understand better what is a typical day for our user, and the learning process they go through. In this context, what How would you approach that day, what kind of questions do you ask, how do you observe the user. Are there defined practices that exist? Also what wouldn't you do? Did you have some bad experience out of this?

  • Are there well-known PowerShell coding conventions?

    - by Tahir Hassan
    Are there any well-defined conventions when programming in PowerShell? For example, in scripts which are to be maintained long-term, do we need to: Use the real cmdlet name or alias? Specify the cmdlet parameter name in full or only partially (dir -Recurse versus dir -r) When specifying string arguments for cmdlets do you enclose them in quotes (New-Object 'System.Int32' versus New-Object System.Int32 When writing functions and filters do you specify the types of parameters? Do you write cmdlets in the (official) correct case? For keywords like BEGIN...PROCESS...END do you write them in uppercase only? It seems that MSDN lack coding conventions document for PowerShell, while such document exist for example for C#.

  • How do you balance documentation requirements with Agile developments

    - by Jeremy
    In our development group there is currently discussions around agile and waterfal methodology. No-one has any practical experience with agile, but we are doing some reading. The agile manifesto lists 4 values: Individuals and interactions over processes and tools Working software over comprehensive documentation Customer collaboration over contract negotiation Responding to change over following a plan We are an internal development group developing applications for the consumption of other units in our enterprise. A team of 10 developers builds and releases multiple projects simultanously, typically with 1 - maybe 2 (rarely) developer on each project. It seems to be that from a supportability perspective the organization needs to put some real value on documentation - as without it, there are serious risks with resourcing changes. With agile favouring interactions, and software deliverables over processes and documentation, how do you balance that with the requirements of supportable systems and maintaining knowledge and understanding of how those systems work? With a waterfall approach which favours documentation (requirements before design, design specs before construction) it is easy to build a process that meets some of the organizational requirements - how do we do this with an agile approach?

  • Unrecoverable error during WUBI installation

    - by john
    I tried to install 12.10 on my PC with Windows 7 installed, but I don't have a CD drive and my PC doesn't support USB booting, so I tried the Windows Installer (WUBI). I had the ISO image mounted with daemon tools, so the Windows installer took those files and used them (I guess, because it didn't download any files). Everything went right, but when it prompted me to reboot, I rebooted the PC and then it starts to install, but when the installation process starts, a message that says: The installation found a unrecoverable error. pops out and makes me reboot, then when I select Ubuntu in the operating system selection screen, it says that an error occurred.

  • Limiting Audit Exposure and Managing Risk – Q&A and Follow-Up Conversation

    - by Tanu Sood
    Thanks to all who attended the live ISACA webcast on Limiting Audit Exposure and Managing Risk with Metrics-Driven Identity Analytics. We were really fortunate to have Don Sparks from ISACA moderate the webcast featuring Stuart Lincoln, Vice President, IT P&L Client Services, BNP Paribas, North America and Neil Gandhi, Principal Product Manager, Oracle Identity Analytics. Stuart’s insights given the team’s role in providing IT for P&L Client Services and his tremendous experience in identity management and establishing sustainable compliance programs were true value-add at yesterday’s webcast. And if you are a healthcare organization looking to solve your compliance and security challenges, we recommend you join us for a live webcast on Tuesday, November 29 at 10 am PT. The webcast will feature experts from Kaiser Permanente, PricewaterhouseCoopers and Oracle and the focus of the discussion will be around the compliance challenges a healthcare organization faces and best practices for tackling those. Here are the details: Healthcare IT News Webcast: Managing Risk and Enforcing Compliance in Healthcare with Identity Analytics Tuesday, November 29, 201110:00 a.m. PT / 1:00 p.m. ET Register Today The ISACA webcast replay is now available on-demand and the slides are also available for download. Since we didn’t have time to address all the questions we received during the live Q&A portion of the webcast, we have captured responses to the remaining questions here. Please continue to provide us your feedback and insights from your experience in deploying identity compliance solutions. Q. Can you please clarify the mechanism utilized to populate the Identity Warehouse from each individual application's access management function / files? A. Oracle Identity Analytics (OIA) supports direct imports from applications. Data collection is based on Extract, Transform and Load (ETL) that eliminates the need to write connectors to different applications. Oracle Identity Analytics’ import engine supports complex entitlement feeds saved as either text files or XML. The imports can be scheduled on a periodic basis or triggered as needed. If the applications are synchronized with a user provisioning solution like Oracle Identity Manager, Oracle Identity Analytics has a seamless integration to pull in data from Oracle Identity Manager. Q.  Can you provide a short summary of the new features in your latest release of Oracle Identity Analytics? A. Oracle recently announced availability of enhanced Oracle Identity Analytics. This release focused on easing the certification process by offering risk analytics driven certification, advanced certification screens, business centric views and significant improvement in performance including 3X faster data imports, 3X faster certification campaign generation and advanced auto-certification features, that  will allow organizations to improve user productivity by up to 80%. Closed-loop risk feedback and IT policy monitoring with Oracle Identity Manager, a leading user provisioning solution, allows for more accurate certification reviews. And, OIA's improved performance enables customers to scale compliance initiatives supporting millions of user entitlements across thousands of applications, whether on premise or in the cloud, without compromising speed or integrity. Q. Will ISACA grant a CPE credit for attending this ISACA-sponsored webinar today? A. From ISACA: Hello and thank you for your interest in the 2011 ISACA Webinar Program!  Unfortunately, there are no CPEs offered for this program, archived or live.  We will be looking into the feasibility of offering them in the future.  Q. Would you be able to use this to help manage licenses for software? That is to say - could it track software that is not used by a user, thus eliminating the software license? A. OIA’s integration with Oracle Identity Manager, a leading user provisioning solution, allows organizations to detect ghost accounts or unused accounts via account reconciliation. Based on company’s policies, this could trigger an automated workflow for account deletion or asking for further investigation. Closed-loop feedback between the two solutions would then allow visibility into the complete audit trail of when the account was detected, the action taken, by whom, when and the current status. Q. We have quarterly attestations and .xls mechanisms are not working. Once the identity data is correlated in Identity Analytics, do you then automate access certification? A. OIA’s identity warehouse analyzes and correlates identity data across various resources that allows OIA to determine a user’s risk profile, who the access review request should go to, along with all the relevant access details of the user. The access certification manager gets notification on what to review, when and the relevant data is presented in a business friendly screen. Based on the result of the access certification process, actions are triggered and results recorded and archived. Access review managers have visual risk indicators that also allow them to prioritize access certification tasks and efforts. Q. How does Oracle Identity Analytics work with Cloud Security? A. For enterprises looking to build their own cloud(s), Oracle offers a set of security services that cloud developers can leverage including Oracle Identity Analytics.  For enterprises looking to manage their compliance requirements but without hosting those in-house and instead having a hosting provider offer managed Identity Management services to the organizations, Oracle Identity Analytics can be leveraged much the same way as you’d in an on-premise (within the enterprise) environment. In fact, organizations today are leveraging Oracle Identity Analytics to manage identity compliance in both these ways. Q. Would you recommend this as a cost effective solution for a smaller organization with @ 2,500 users? A. The key return-on-investment (ROI) on Oracle Identity Analytics is derived from automating compliance processes thereby eliminating administrative overhead, minimizing errors, maintaining cost- and time-effective sustainable compliance processes and minimizing audit exposures and penalties.  Of course, there are other tangible benefits that are derived from an Oracle Identity Analytics implementation as outlined in the webcast. For a quantitative analysis of your requirements and potential ROI calculation, we recommend you refer to the Forrester Study on Total Economic Impact of Oracle Identity Analytics. For an in-person discussion, please email Richard Caldwell.

  • Cowboy Agile?

    - by Robert May
    In a previous post, I outlined the rules of Scrum.  This post details one of those rules. I’ve often heard similar phrases around Scrum that clue me in to someone who doesn’t understand Scrum.  The phrases go something like this: “We don’t do Agile because the idea of letting people just do whatever they want is wrong.  We believe in a more structured approach.” (i.e. Work is Prison, and I’m the Warden!) “I love Agile.  Agile lets us do whatever we want!” (Cowboy Agile?) “We’re Agile, but we use a process that I’ve created.” (Cowboy Agile?) All of those phrases have one thing in common:  The assumption that Agile, and I mean Scrum, lets you do whatever you want.  This is simply not true. Executing Scrum properly requires more dedication, rigor, and diligence than happens in most traditional development methods. Scrum and Waterfall Compared Since Scrum and Waterfall are two of the most commonly used methodologies, a little bit of contrasting and comparing is in order. Waterfall Scrum A project manager defines all tasks and then manages the tasks that team members are working on. The team members define the tasks and estimates of the stories for the current iteration.  Any team member may work on any task in the iteration. Usually only a few milestones that need to be met, the milestones are measured in months, and these milestones are expected to be missed.  Little work is ever done to improve estimates and poor estimators can hide behind high estimates. Stories must be delivered every iteration, milestones are measured in hours, and the team is expected to figure out why their estimates were wrong, even when they were under.  Repeated misses can get the entire team fired. Partially completed work is normal. Partially completed work doesn’t count. Nobody knows the task you’re working on. Everyone knows what you’re working on, whether or not you’re making progress and how much longer you think its going to take, in hours. Little requirement to show working code.  Prototypes are ok. Working code must be shown each iteration.  No smoke and mirrors allowed.  Testing is done in lengthy cycles at the end of development.  Developers aren’t held accountable. Testing is part of the team.  If the testers don’t accept the story as complete, the team can’t count it.  Complete means that the story’s functionality works as designed.  The team can’t have any open defects on the story. Velocity is rarely truly measured and difficult to evaluate. Velocity is integral to the process and can be seen at a glance and everyone in the company knows what it is. A business analyst writes requirements.  Designers mock up screens.  Developers hide behind “I did it just like the spec doc told me to and made the screen exactly like the picture” Developers are expected to collaborate in real time.  If a design is bad or lacks needed details, the developers are required to get it right in the iteration, because all software must be functional.  Designers and Business Analysts are part of the team and must do their work in iterations slightly ahead of the developers. Upper Management is often surprised.  “You told me things were going well two months ago!” Management receives updates at the end of every iteration showing them exactly what the team did and how that compares to what' is remaining in the backlog.  Managers know every iteration what their money is buying. Status meetings are rare or don’t occur.  Email is a primary form of communication. Teams coordinate every single day with each other and use other high bandwidth communication channels to make sure they’re making progress.  Email is used only as a last resort.  Instead, team members stand up, walk to each other, and talk, face to face.  If that’s not possible, they pick up the phone. IF someone asks what happened, its at the end of a lengthy development cycle measured in months, and nobody really knows why it happened. Someone asks what happened every iteration.  The team talks about what happened, and then adapts to make sure that what happened either never happens again or happens every time.   That’s probably enough for now.  As you can see, a lot is required of Scrum teams! One of the key differences in Scrum is that the burden for many activities is shifted to a group of people who share responsibility, instead of a single person having responsibility.  This is a very good thing, since small groups usually come up with better and more insightful work than single individuals.  This shift also results in better velocity.  Team members can take vacations and the rest of the team simply picks up the slack.  With Waterfall, if a key team member takes a vacation, delays can ensue. Scrum requires much more out of every team member and as a result, Scrum teams outperform non-Scrum teams working 60 hour weeks. Recommended Reading Everyone considering Scrum should read Mike Cohn’s excellent book, User Stories Applied. Technorati Tags: Agile,Scrum,Waterfall

    I am in process of migrating my old domain (www.oldurl.com) to new domain (www.newurl.com). Almost all the content,URL structure as well database is same except for few URL's and only difference will be in the domain name. I have made entries in the Apache's .htaccess file to set 301 redirect and currently have blocked all search engines from crawling my new domain by setting in robot.txt file. I am not sure how i will handle the duplicate content issue as when i will make the new domain go live. Should i block search engines to index/crawl my old domain? i am new to this field and not sure if this is actually any duplicate content issue or not.

  • What version of Java should I target for applets?

    - by Christopher Horenstein
    I recently deployed an applet that seems to require Java 6 Update 24. I assume the reason for this requirement is the matching JDK version I used to create the applet (I am new to Java). The fact that my applet requires a Java download/update for users who already have some version of Java installed is a big concern for me; the applets I'm creating slip into a web comic, so it's very disruptive. Having used the most recent version of Java, it seems as though I am able to assume that most of the readers I get will have to update Java to continue reading/playing. Is there a best practice concerning which version of Java to use to make the process of using an applet easy for end-users? Any reading material on this would be very helpful. Should I be using an older version of Java if I don't require new features? I am using Slick for 2D games.

  • How to convincing Programmers that 'being in the zone' [coding] isn't always beneficial for the project?

    - by hawkeye
    In this book review: http://books.slashdot.org/story/11/06/13/1251216/Book-Review-The-Clean-Coder?utm_source=slashdot&utm_medium=twitter Chapter 4 talks about the coding process itself. One of the hardest statements the book makes here is to stay out of "the zone" when coding. Bob asserts that you lose parts of the big picture when you go down to that level. While I may struggle with that assertion, I do agree with his next statement that debugging time is expensive, so you should avoid having to do debugger-driven development whenever possible. He finishes the chapter with examples of pacing yourself (walking away, taking a shower) and how to deal with being late on your projects (remembering that hope is not a plan, and being clear about the impact of overtime) along with a reminder that it is good to both give and receive help, whether it be small questions or mentoring others. they talk about how 'being in the zone' - can actually be detrimental to the project. How do you convince your team members that this is the case?

  • How to teach computer science ?

    - by proferikson
    I am just starting to teach computer science. It's just the basic level. I'm finding that I sometimes don't know how to approach topics in a way that lets students easily understand. I've found that the best thing is to use analogies. A terrible one, that worked well, was presenting recursion by using the process of eating a burger. (You eat one bite, then you eat the rest). Interesting real world examples do wonders here. I'd like to know the techniques you have used for teaching, or teachers you've had have used that proved particularly effective. I'd also like to know your best analogies and examples for topics in CS101, especially for those harder to grasp topics. I'm teaching the class in Java (as required).

  • Geotargeted subfolder questions (Portugal/Brazil and Switzerland)

    - by Lucy
    We are at the beginning of the process to get multilingual versions of a website. We will be using subfolders working off the core domain (eg mydomain.com/fr/), set the geotargeting at webmaster tools and set hreflang attribute. I would really appreciate your help with a couple of questions. 1/Portuguese: we will have a Portuguese language version of the site. Our intention is to use this to cover users in both Portugal AND Brazil. ie, we are not going to do separate folders mydomain.com/pt/ and mydomain.com/br/ Can I use 2 hreflang attributes for this language version to tell Google it covers Brazil AND Portugal? What country code to use for this subfolder? 2/Switzerland Does anyone have best practice advice how to do this? One one hand, the subfolder should be mydomain.com/ch/ but as Switzerland covers 2 language possibilities (French AND German) - what to do? thanks

  • managing information/functionality on shared common project classes

    - by ilansch
    In my company, we have a common solution the contains common projects (2 projects so far, one for .net 3.5 and one for .net 4.5). My main problem is that during time, a lot of code is added, for example hosting a process as windows service is a class called ServiceManagement, But no one but the developer knows it, and if someone wants to use this shared class, he does not know it exist. So i am looking for a way to document and manage all the classes with tags, a 3rd party util/web util, that i can search for tags and maybe find common classes that i can use (if we keep all our code well-documented). Does anyone familiar with sort of tools ?

  • How to shorten brain context switch delay when need to use new technology\framework?

    - by gasan
    The problem is when I have to deal with a new framework\library\language it completely slows my work process, at first it's kind of shock, you're sitting on your place about a day doing nothing surfing the net, because you simply can't do anything even read docs, then, on the second day I realize that I definitely should do something and starting read about it, then I realize that I don't understand it, then I'm reading until I got feeling that I should show some results immediately and then I'm writing the code quite fast and the job doesn't seem to be difficult. Then job is done and I won't probably return to that technology\framework for a month or a year or never at all. And I will almost certainly forget almost everything about it after a month. To illustrate by checkpoints I experience: shock, long studying times, work with the new tech briefly, never use it afterwards, then I completely forget it. So what would be the solution here?

  • Good questions to ask a potential new boss?

    - by David Johnstone
    I first asked this question on Stack Overflow, but it turns out this is a better place for it. Imagine you were working as a software developer. Imagine that the manager of your team leaves and your company is looking for a replacement. Imagine that as part of the hiring process you had the opportunity to talk with him. You are not the only person doing an interview, and while it is not ultimately your decision whether or not to hire him, you do have an influence. What questions would you ask? What would you talk with him about?

  • file acess slow after deletion of many files

    - by stefan
    I recently accidentally created millions of files in one folder (rougly 5 million) and due to limitations I couldn't process them correctly (maximum argument count exceeded for wc / ls and such stuff). So I deleted them, which took quite a while, but now they're gone. I deleted the files with a regular rm. It weren't any system files. So the files are definitively deleted, but the system is very slow on file stuff now. ls, cat and auto-complete by pressing tab freezes the terminal for several seconds. Is this some sort of fragmentation issue? Is it an issue with the files beeing still somehow present?
