• Moving dozens of existing standalone retail sites to one central inventory database: what should I know going in?

  - by palintropos

  This will be the first project of this scale that I have attempted, and the first time I have run a website at all (much less dozens) using an off-site database. In particular, I'd like to know: what sort of optimizations I should read up on to make this run as smoothly as possible? any pitfalls/gotchas wiser, more experienced folk are aware of I should be on the lookout for, and what damage-control and preventative measures I should take against the nightmare scenario of the main server (hosting the database) having an outage, grinding over 100 websites to a halt (because they have no access to the product data).

• Flash Retirement - HTML to be "the one"

  - by RichMill

  I will update this blog post as we get closer to the retirement of the Flash portal. As you might have read the support.oracle.com  flash site will be replaced with what you see in supporthtml.oracle.com,  once we get the rest of the features and functions ported over to the html site. The HTML site is written using Oracle's ADF stack. So we are now pretty much 100% eating our own dog food.  More details to follow.

• Correct process for creating builds reliant on 3rd party packages

  - by Patrick

  I work on a Symfony 2 codebase. We use a number of third-party packages (most are in the Symfony Standard Edition). We use composer for dependencies. We current have all of our third-party code committed in our repository (after changing .gitignore files) to ensure stability. According to Proper Programming Practices™, we are not supposed to have any third-party packages in our repo. We are supposed to pull them down and include them at build time. How are we to do proper QA and debugging when at any given time our dependencies could push an update that breaks functionality?

• How to manage Agile developers working with traditional (serial) business persons?

  - by Riggy

  Good afternoon, My work environment has some problems. Our IT team is trying to be more agile, but we're not really getting buy-in from the business. They attend our daily stand-ups and sprint reviews, and they help with sprint planning, but then they turn around and do 4 months of requirements gathering for a project before moving forward with a (mostly) serial development style. The sprint goals are things like "get XX% closer to release". For the IT team, they've turned the Sprints into a sort of death march. We end a Sprint one day and start a new Sprint the very next day. There's no reflection or changes done between sprints, only during. Having never done any of the agile methodologies before, I haven't had a very pleasant introduction to them. So my questions are: 1) Should there be some time (perhaps a week or so) between sprints to do the reflection/introspection/changes/etc.? Or are back-to-back-to-back sprints the norm? 2) Is there any chance for survival for an agile team with no agile business counter-parts? If not, are there some transitional methodologies or even tips for moving the business towards an iterative if not necessarily agile mindset? 3) Should your entire team be on every sprint? We have almost 20 programmers on a single sprint but working on completely different projects (typically teams of 3-5, sometimes larger). Is it normal to have a single sprint or should we be trying to manage multiple independent sprints? Should we be trying to keep the multiple sprints in concurrent lockstep or should their timetables be allowed to overlap and be flexible? Any thoughts or advice is appreciated. This is my first time coming over from SO for a question, so please let me know if there are better ways to phrase these kinds of questions (faq was rather helpful, but still not sure I'm following it perfectly). Thanks!

• Inspiring People

  - by barrem23

  So I work with a few people that I feel are intelligent but don't seem to be working out well. After working with them for a while I have seen the flashes of brilliance but mostly I see a reliance on others. What I mean by this is that most times it seems like at the first moment of trouble they go ask for help. Now personally I am all for helping and spend a significant portion of time helping others with whatever they need, but after helping others for so long I have noticed a disturbing trend. These people seem terrified that they might make a mistake and because of this they don't try. So my question is how can I motivate someone who is afraid of making a mistake? In my career I have always learned the most by making mistakes and learning from them. Personally I feel that if I hadn't learned so much I would never have made it as far as I have. So how can I get them to discover that they have the ability to figure it out themselves and that if they make a mistake and learn from it they will be better off. I feel that if I can discover some way to properly motivate them that we all will be better off.

• Does your team develop their supporting tools or this should be outsourced out of it?

  - by Pierre 303

  By supporting tools, I mean: reference data manager, like virus definition for anti-virus software test data generator level builders for games simulators or advanced mocking systems Does the team building the core product (in the case above, the game or the anti-virus) should be part of the development of the supporting tools significantly, or this is a task you would outsourced out of the team to help it focus on the product? I don't have enough experience to evaluate the pros & cons of each, so I'm hopping you would come up with personal experiences to share, or even studies or papers you read on the subject.

• How to move from Programmer to Project Lead

  - by DoctaStooge

  At my job, I'm currently a programmer, but in the next few weeks I'll be taking control my own project. I was wondering if anyone else here has been in the same situation, and if so, what advice you can offer to help me be able to better run my project. Experience in dealing with contractors would be greatly appreciated. A little more info: Project will have 3 people including myself, with extra people coming in when needing testing. The project has been programmed mainly by 2 people I would like to contribute to the programming as I like doing it and think I can add to the program, but am afraid of how the contractors will react. I don't want to create bad feelings which may harm the project. EDIT: Forgot to mention that I'll have to be picking up communications with customers to make sure their needs are met. Any advice on talking to customers cold would be greatly appreciated. EDIT 2: This is not a new project, I'm picking it up around version 6. Sorry that I didn't make it clear before.

• Consuming too much power on a Dell 15R

  - by Daniel Davis

  I'm new to Ubuntu, and I've just installed Ubuntu 11.10, and I must say I really like it a lot. I'm getting used to Ubuntu faster than I thought but the only issue I'm having is the power consumption. I have a " dell 15R with BIOS a07" and I uninstalled Ubuntu 11.04 because of some glitches I hated. None of those appear on this Ubuntu but now my computer discharges way too quick. when I check the power icon, it states that I have like 3:45 min remaining, which is fairly the same as what win7 and Ubuntu 11.04 used to tell me but 15 min later I check again and it gives me only 1:15 min remaining. Also, my computer seems to get a lot hotter than it used to. Is there more options to control the power usage on my laptop?

• xubuntu 12.04 restarts after suspend - only from my account

  - by Yoav Aner

  After installing a clean xubuntu 12.04 I noticed that when I suspend, the computer suspends and turns itself off (you see the lights go off, and a click sound from the HD or fans), but then about 2 seconds later it turns itself back on again... The odd thing is that: It doesn't happen when booting from the liveCD I created another user account. When I log onto this account I can suspend fine. The computer stays off until I press the ON button When I remove my .config folder and it's clean - I can also suspend without problem on my account So it seems that something in my user config is causing this, but I can't work out what it might be. I tried diffing the two .config folders, and also all processes running with one account compared to the other (ps -ef |grep <username>), but couldn't find anything obvious that might be causing this...

• How to determine the size of a package in terminal prior to downloading?

  - by user14590

  When using apt-get install <package_name>, and there are dependencies that need to be downloaded, the terminal outputs names of additional packages and total size, and asks for confirmation before downloading. But, when dependencies are satisfied and nothing but the named package needs to be downloaded there is no size output and no confirmation. When using Synaptic, I can see the total size that new packages that will use after installation but no way to see the size that needs to be downloaded, except to go from package to package and use properties to see the compressed size. I would like to know if there is a way to see the size of a package(s) in terminal and Synaptic prior to downloading and installing it/them?

• List all versions of a package

  Is there a equivalent of this command; yum list kernel-headers --showduplicates on Ubuntu with apt-get, apt-cache etc. The above command lists various versions of the kernel-headers rpm available on F20/RHEL or installations.

• How do I know if a particular build has a particular version control change in it?

  - by carleeto

  Let's say I have a build. I need to know if a particular changelist/commit is present in that build. How would I solve this problem? I can think of a couple of possible approaches: 1) Add the changelist number into the binary so that I can look somewhere in the GUI and know what the changelist number is. I can then use this information to determine if the change I'm interested in is within that build. 2) Tag version control using some string that uniquely identifies that build. What unique string would I use? Is either of these two better? Are there any other better approaches? The solution would have to work for both Mac and Windows builds.

• Does tweeting 9 to 5 hurt job applicants?

  - by evadeflow

  If you were looking into a job applicant's background and discovered that he or she has 1200 followers on Twitter and averages 50 tweets per day (more than half of which are during business hours), would it affect your hiring decision? How and why? Personally, I'd be a little worried about the candidate's ability to focus on the job at hand if they're constantly checking in with their 'tweeps' thoughout the day. In non-tech jobs, a lot of companies simply block Twitter as an irrelevant distraction. But it can be a useful resource---to programmers in particular. I just wonder how much is too much. At what point does it become a red flag?

• Battery life decreased after upgrade to 11.04

  - by bruno077

  After upgrading from Ubuntu 10.10, my battery life has decreased dramatically. There was a bug in Ubuntu 10.10 where the Load Balancing Tick and Kworker would interrupt and wake-up the cpu too much, and this wasn't normal. I applied a gnome-power-manager fix back then, following this question, which leads to this bug report, and battery life increased to 3.5 hours. I'm getting around two hours of battery-life in Natty, and calling Intel's powertop reveals that this bug is back. Is there a fix for Natty yet? I have a Core 2 Duo ULV, Thinkpad Edge 13

• How to structure an application which reads UPC barcodes

  - by tugberk

  I have no previous experience on creating a project for a seller which will use barcode reader. I am trying to put together a small project but I cannot figure out how the pieces should glue together. I will create a sample with Motorola Scanner SDK to read barcodes and from that point, I have couple of questions: How UPC barcodes work in general? AFAIK, a barcode stores the manufacturer and product info but no price data. Should I store price information inside a database which corresponds to barcode data? I would really appreciate if you can guide me here.

• Patients are Running out of Patience

  - by Naresh Persaud

  Healthcare is in a dramatic state of change globally and the change is being driven by patients. Patients are no longer content to wait in line, endure appointment delays and stay on hold waiting for a health insurance representative. Instead, patients are demanding on-line access to physicians, joining communities with fellow patients, scheduling appointments online and resolving claims issues over email.  To accomodate the demand for patient connectivity, providers are innovating to find new ways to collaborate with patients. To address the demand, providers are providing 24/7 access online and pioneering ways to deliver care via mobile devices -  for example using your iPhone as a heart monitor. Patient vitals can be collected before the patient even walks into the clinic.  These new approaches promise to enhance the patient experience and reduce the cost of care. Time is money both for the patient and the provider. For insurance companies, all of this is  welcome news because it reduces un-necessary time with the physician which reduces the number of claims.  Oracle is focused on enabling and securing the experience. The video below shares the Oracle healthcare transformation story. asas

  - by bbb

  we want to make a frame work for our company. Our company mission is developing web applications and CMS and websites. Till now we had a lot of problems with the various types of codding. we didnt have a frame work and every programmer codes as he wants and it was too hard for the others to edit them. Now we want to make a frame work for the company. We want to make an archive of dll files that are written by our self our other and make the programmers to use just from them and we want to make a frame work for the type of codding. WE NEED A STRUCTURE FOR THE COMPANY. I dont know how to do this and what is the first and second and third step to do this. I need some guidance about it. For example I say that the frame work should contains the followings: The base should be SOLID The method should be Code-First The standards should be Naming Convention The type should be 3 layer programming The method should be MVC We should use from our dll archive The UI should be with HTML and CSS And using from Bootstrap Am I right or not or is it complete or...???

• Installing package + dependancies and removing them all

  - by Sman789

  I currently use Xubuntu and was considering installing/trying GNOME Shell or Cinnamon by installing their respective metapackage. However, doing so would result in a massive number of dependencies being installed which would be almost impossible to remove individually at a later date if I decided I didn't like it. I wonder, therefore, if there is a way that I can track which packages Synaptic automatically downloads as part of the process and create a script of some sort to remove them all as well. I could then rest assured that if I don't like any of my new desktop environments, I can remove them in full without leaving a load of other applications and libraries lying around. Thankyou for any help! :)

• Why do exclusively outsourcing projects as a company?

  - by user19833

  A prospective employer told me they took a company level decision to only do outsourcing projects. I do not understand why did they take such a decision and the guy I talked to did not elaborate. He further said only that "their intention is to build software components". Since they are growing quite fast and reached around 300 employees, shouldn't they be at least open to the possibility of having a project of their own, maybe? All other companies I've had contact with were at least open to have one in the future.. I talked to a few of their employees and some are working in parallel on more than 2 outsourced projects (dividing time something like 4 + 4 hours / day). It seemed like a lot of projects with a period of a few months, maybe half an year come and go... Why would a company choose to provide only outsourcing services like that? How does it work to keep hundreds of people on outsourced projects with a seemingly high project turnover rate?

• Steps to manage a large project [closed]

  - by l46kok

  Software development is an area where parallel development to its fullest form is very difficult to achieve, although you could get reasonably close with the right design. This is especially true for game development. That being said, if you are designing a game from scratch from engine to front end, what steps should be taken in order? How would you efficiently manage your project and your team? I'm asking because several people and I are interested in working on a relatively large project for learning purposes. Initially, we were going to use a proprietary engine like Unity, but since we wanted to learn how the engine works, we're going to start from bottom. I'd appreciate any suggestions that you guys can provide me.

• Good practice on Visual Studio Solutions

  - by JonWillis

  Hopefully a relativity simple question. I'm starting work on a new internal project to create tractability of repaired devices within the buildings. The database is stored remotely on a webserver, and will be accessed via web API (JSON output) and protected with OAuth. The front end GUI is being done in WPF, and the business code in C#. From this, I see the different layers Presentation/Application/Datastore. There will be code for managing all the authenticated calls to the API, class to represent entities (business objects), classes to construct the entities (business objects), parts for WPF GUI, parts of the WPF viewmodels, and so on. Is it best to create this in a single project, or split them into individual projects? In my heart I say it should be multiple projects. I have done it both ways previously, and found testing to be easier with a single project solution, however with multiple projects then recursive dependencies can crop up. Especially when classes have interfaces to make it easier to test, I've found things can become awkward.

• How to educate business managers on the complexity of adding new features? [duplicate]

  - by Derrick Miller

  This question already has an answer here: How to educate business managers on the complexity of adding new features? [duplicate] 3 answers We maintain a web application for a client who demands that new features be added at a breakneck pace. We've done our best to keep up with their demands, and as a result the code base has grown exponentially. There are now so many modules, subsystems, controllers, class libraries, unit tests, APIs, etc. that it's starting to take more time to work through all of the complexity each time we add a new feature. We've also had to pull additional people in on the project to take over things like QA and staging, so the lead developers can focus on developing. Unfortunately, the client is becoming angry that the cost for each new feature is going up. They seem to expect that we can add new features ad infinitum and the cost of each feature will remain linear. I have repeatedly tried to explain to them that it doesn't work that way - that the code base expands in a fractal manner as all these features are added. I've explained that the best way to keep the cost down is to be judicious about which new features are really needed. But, they either don't understand, or they think I'm bullshitting them. They just sort of roll their eyes and get angry. They're all completely non-technical, and have no idea what does into writing software. Is there a way that I can explain this using business language, that might help them understand better? Are there any visualizations out there, that illustrate the growth of a code base over time? Any other suggestions on dealing with this client?
