• What's the easiest way to move from one Macintosh to another?

  - by schnapple

  Here's the story: Company bought me a $599 Mac mini (as of this writing, 2.26GHz/160GB HD/2GB RAM) I have it set up to some extent with software for development Company decides it needs a second Mac for QA I convince company to buy the $799 Mac mini for the second machine (as of this writing, 2.53GHz/320GB HD/4GB RAM), let me have it for development, and let QA have the $599 Mac mini Company does just that, now I have both So, what's the best way to move from one of these to the other? Just set up everything on the second one and be done with it? Can I transfer things from the first to the second somehow? I'm running Time Machine backups to an external drive on the $599 Mac mini, if that helps. Also both of these will be on the network at the same time, other than renaming one of the machines are there considerations to be had there?

• How do I scale EC2 and push out code / data to my instances?

  - by chris

  Unfortunately I only have a limited knowledge of server architecture, I come from a development background. I am looking to ensure my new app can scale properly using EC2. I currently have a T1.micro for development running Windows with SQL server 2008. The system allows students to come to our site to search for a mentor, update their profile with pictures and employment history etc. Roughly the same sort of work as a LinkedIn profile. I need this to be able to scale very quickly without wasted resources. I understand the following is important. Separation of data, application etc. I will achieve this I think by hosting images using S3, Database instance via RDS and upgrade the EC2 instance. My main question is: How do I push data / code out to multiple ec2 / RDS instances seamlessly?

• Should I choose KVM/XEN over OpenVZ or use them together?

  - by Krystian

  I've got a dual xeon e5504 server, with [for now] only 8GB of ram. Storage is'n impressive either: 3x 146GB sas in raid5 + 500GB sata drives. Currently it works as a development server, but it's over speced for our needs and since our development methods changed through last 2 years we decided it will work as a production system for some of our applications + we would like to have a separate system for testing/research. Our apps are mainly web apps deployed on tomcats [plural as some of the apps require older versions] and connected to Postgres. I would like to have a production system, where only httpd+tomcat+db are setup and nothing else runs there. Sterile system. Apart from that, I would like a test system, where I can play with different JVM settings, deploy my test apps, play with tomcat/httpd settings and restart them without interfering with the production system. Apart from that, I would like to be able to play with different linux flavors, with newer kernels to test how they work etc. I know, this is not possible with OpenVZ and I would have to choose KVM for that. I am thinking about merging the two, and setting up a KVM to be able to work with different systems [linux only to be frank] + use openVZ to setup separate machines for my development needs. I would simply go with that, but reading here and there about the performance impact full virtualization has over containers and looking at the specs of my server makes me think twice about it. I don't want to loose too much performance, especially because of the nature of my apps [few JVMs running at the same time]. It will be my first time with virtualization, apart from using desktop virtualbox/vmserver. Although I am a fast learner I don't want to mess with the main system so much that it will break the production apps or make them crawl. Although they are more or less internal apps and they don't produce much load, they need to be stable. I've read, that KVM host is a normal linux installation and it allows to run normal processes on it. If that is so, does it allow to run openVZ as well? I mean... can I have KVM and OpenVZ running on the same system/kernel? Or do I have to setup another system to run OpenVZ containers? How much performance impact can this have for me? Will my hardware suffice? oh and one more thing... unfortunately I'm quite limited with the funds... I'm looking for a free solution only :/

• What a .NET developer should know or practice (know how to do)? [closed]

  - by Olav

  I would like to have a list of basic tasks that .NET developers of different flavors using Visual Studio/SQL Server should be able to do. Ideally with a kind of lab environment where I could practice. VB.NET or C#, latest versions of ASP.NET, WPF and Silverlight. I am looking for small practical "atomic" tasks (like adding a db connection for example) I am looking for some existing labs/lists rather than specific points in the answers. (But I would not mind collaborating in developing material).

• Add users in Windows machine without AD

  - by guillem

  I have several development machines where I am the administrator. We are using AD in my organization but is maintained by and offshore IT group any request takes a long time. We are currently granting access to developers on development machines manually so it's a bit annoying to maintain although at least it's fast. We have also a lot of external consultants that need to use those machines for some time. Is there any tool or method to maintain a set of users synced on those machines without the need add them to an AD group?

• Programming During a Crisis

  - by Duracell

  Hello, I'm having difficulty turning this into a proper question, but here goes... Some of you may have heard about the flooding happening in Queensland, Australia. Well, I'm in the inner suburbs of Brisbane right now; the river has been slowly creeping toward my house since Tuesday. When I left for work this morning it was twenty meters down the road when it is normally kilometers away. Within hours of the distater striking, the government already had some pretty good web applications available for people to get information about what was happening and where the flood was predicted to rise. They also set up a database for people to search for the whereabouts of relatives or could register their location for others to see. Has anyone been involved in the development of these kinds of projects before? It's interesting that they could churn out this software in what appeared to be less than a day when the average development house could take weeks at best. In what ways did it differ from a 'normal' project? Any other thoughts?

• Gnome fallback move to workspace not working - Ubuntu 14.04

  - by iulianis

  I have recently switched to Ubuntu 14.04 but using the gnome fallback desktop environment. The thing that is not working for me is that when I right click on a window's top bar and then click Move to Workspace Up for example, it puts the window in that workspace but it also keeps it in the current workspace. I've tried all options but it just wouldn't work :( Anyone experienced the same and found a solution?

• Upgrading to 9.2 - Info You Can Use (part 2 - Get Hands On Experience)

  - by John Webb

  Our guest blogger, Rebekah Jackson, continues with a series of helpful hints on planning your upgrade to PeopleSoft 9.2. Get Hands-On Experience With a an Easy to Install Demo Image Once you have identified the features you believe can add value (see part 1 of this series here), we recommend that you use our Demo Images to quickly create a PeopleSoft environment where you can try out the new features. The Demo Images are virtual machines that run in VirtualBox.   They contain a fully functioning PeopleSoft environment, including the database, PeopleTools, and the application.  These images can be loaded onto nearly any sized machine that meets the specs outlined in the documentation, including a powerful desktop machine.     The image allows you to very quickly deploy a fully functioning PeopleSoft instance that you can use to explore new features and functions or run a conference room pilot. To take advantage these Demo Images: Go to the Demo Images Home Page (Doc id 1552548.1) on My Oracle Support. Use the " Demo Image Quick Start Guide" and additional documentation links on that page to download and install your desired Demo Image. New Demo Images are posted for each product area approximately every 10 weeks, available shortly after the corresponding patching image. When installed, use the Demo Image to explore the desired features and capabilities. Important Notes: - It is not required to use the Demo Images to evaluate features and functions – any 9.2 instance will support this. We recommend use of the Demo Images because the setup and configuration is dramatically faster than doing a traditional PeopleSoft install. - For those looking to explore new features and capabilities on PeopleSoft 9.1 releases, we have provided virtual machine images using the Oracle Virtual Machine technology. Details and links are available in Oracle’s PeopleSoft Virtualization Products page (Doc id 1538142.1). /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Calibri","sans-serif"; mso-bidi-font-family:"Times New Roman";}

• Should I be concerned that I can't program very fast without Google? [closed]

  - by seth

  Possible Duplicate: Google is good or bad for programmer? I'm currently in college to be a software engineer, and one of the main principles taught to us is how to learn for ourselves, and how to search the web when we have a doubt. This leads to a proactive attitude - when I need something, I go get it. Recently, I started wondering how much development would I be able to do without internet access and the answer bugged me quite a bit. I know the concept of the languages and how to use them, but I was amazed by how "slow" things were without having the Google to help in the development. Most of the problems I have are related to specific syntax. For example, reading and writing to a file in Java. I have done this about a dozen times in my life, yet every time I need to do it, I end up googling "read file java" and refreshing my memory. I completely understand the code and fully understand what it does, but I am sure that without Google it would take me a few tries to get the code correct. Is this normal? Should I be worried and try to change something in my programming behaviour?

• apache port number

  - by user983223

  For each development sites I want to have a unique port number. For instance, domain.com:1234 This is what I have in my httpd.conf file. After restart the page domain.com:1234 is not showing in the browser. Is there anything else that I need to do besides what I have already done to make this work? Listen *:1234 <VirtualHost *:1234> DocumentRoot /var/www/dev_sites/test ServerName domain.com:1234 </VirtualHost> It looks like if I go to my local hostname (kk.local:1234) it shows. Is there some sort of dns that I need to do? I really don't want to go into godaddy everytime I add a development site. Is there a way around that?

• Spotlight on an office - Nairobi, Kenya

  - by Maria Sandu

  Hi everyone, my name is Joash Mitei. I am a graduate Intern at Oracle Systems Kenya and I will briefly take you through our offices and the working environment here in Nairobi, Kenya. I’ve been with Oracle since February 2012 and I’m responsible for Applications Pre-sales focusing on Oracle EPM and E-Business Suite. My background is Finance and Accounting therefore joining Oracle was almost a totally a different ball game but the transition has been smooth. The Oracle offices here are located on the second floor of Mebank Towers. We moved to the 2nd floor just three months ago from the 5th floor mainly because of the growing workforce. We are covering the whole Eastern Africa region hence diversity in culture is evident. This is a plus since you get to interact with people of very different backgrounds, cultures and ways of thinking. The building itself is on the outskirts of the CBD hence free from the hustle and bustle of the town. The office is split into different sections; there is a main working area which has an open desk design that fosters interaction between colleagues, there are 4 conference rooms for meetings and presentations, there are 3 quiet rooms for a little privacy when needed and there is a dining area for meals and ‘hanging out’. The working environment is world-class, to say the least. The employees are very professional, quite smart and needless to say, very busy. There are 4 interns covering sales and pre-sales in both Tech and Apps. As an intern you get support from your supervisor but you are required to show initiative yourself and thus the need to be very pro-active and inquisitive. The local management is well structured and communicative to ensure effectiveness and efficiency in the office. Apart from the daily work, we usually have events to boost staff morale such as ‘TGIF hang -out’, football matches against each other or versus other companies, and team building retreats. All these are monumental in fostering the RED POTENTIAL. We also do numerous CSR activities in the local communities . Well, that’s the Kenyan office for you. Glad to be your tour guide. Have a superb day!
