• Automate RAC Cluster Upgrades using EM12c

  - by HariSrinivasan

  One of the most arduous processes  in DB maintenance is upgrading Databases across major versions, especially for complex RAC Clusters.With the release of Database Plug-in  (12.1.0.5.0), EM12c Rel 3 (12.1.0.3.0)  now supports automated upgrading of RAC Clusters in addition to Standalone Databases. This automation includes: Upgrade of the complete Cluster across the nodes. ( Example: 11.1.0.7 CRS, ASM, RAC DB  ->   11.2.0.4 or 12.1.0.1 GI, RAC DB)  Best practices in tune with your operations, where you can automate upgrade in steps: Step 1: Upgrade the Clusterware to Grid Infrastructure (Allowing you to wait, test and then move to DBs). Step 2: Upgrade RAC DBs either separately or in group (Mass upgrade of RAC DB's in the cluster). Standard pre-requisite checks like Cluster Verification Utility (CVU) and RAC checks Division of Upgrade process into Non-downtime activities (like laying down the new Oracle Homes (OH), running checks) to Downtime Activities (like Upgrading Clusterware to GI, Upgrading RAC) there by lowering the downtime required. Ability to configure Back up and Restore options as a part of this upgrade process. You can choose to : a. Take Backup via this process (either Guaranteed Restore Point (GRP) or RMAN) b. Set the procedure to pause just before the upgrade step to allow you to take a custom backup c. Ignore backup completely, if there are external mechanisms already in place.  High Level Steps: Select the Procedure "Upgrade Database" from Database Provisioning Home page. Choose the Target Type for upgrade and the Destination version Pick and choose the Cluster, it picks up the complete topology since the clusterware/GI isn't upgraded already Select the Gold Image of the destination version for deploying both the GI and RAC OHs Specify new OH patch, credentials, choose the Restore and Backup options, if required provide additional pre and post scripts Set the Break points in the procedure execution to isolate Downtime activities Submit and track the procedure's execution status.  The animation below captures the steps in the wizard.  For step by step process and to understand the support matrix check this documentation link. Explore the functionality!! In the next blog, will talk about automating rolling Upgrades of Databases in Physical Standby Data Guard environment using Transient Logical Standby.

• Career Development: What should I learn next after Python? and Why? [closed]

  - by Josh

  Hi all I'm currently learning Python. I want to know what should I learn next out of these programming langauages: PHP Actionscript 3 Objective-C (iPhone applications) I work in the Multimedia industry and have decided to learn Python as a first programming language seriously because I would like to learn the basics of programming, to mainly write scripts at work that Automate task (eg. Edit multiple XML files quickly) At work we have a senior developer who knows Actionscript and PHP very well (although knows PHP better). We also have been developing iPhone applications for 2 weeks, Our senior developer could learn it although we have lots of work currently with PHP and Actionscript 3 type work and haven't had time or reason to pick up iOS development. Here are the reasons I want to learn each language, But I cannot decide what I'll learn next: PHP: I want to learn PHP because it will help with Web Development. PHP is very wanted by employers. Senior developer at work writes everything in it web sites, CMS etc. (including XML checks and scripts), I will learn a lot from him (once I learn the basics). However, I don't want to learn Web because you have to deal with lots of cross-browser problems. Actionscript 3: At work we are looking to put on another developer to help with online activities and very small games (using Actionscript 3.0 and Flash CS5) for (eg. First Aid Activities etc) I would like to do things that have a element of design as I'm better at Photoshop then developing. I want to be creative, I like to interact with users in a fun way. Objective-C (iPhone applications): We are a all mac office, we may get more iPhone, iPad application work(jobs) that need to be created. Work has found it nearly impossible to find good iPhone developers. I like apple products (Macs and iPhones), I would like to make my own games, applications in my spare time(if I knew how). Should I learn Actionscript first because it would be easier to learn then Objective-C? Should I learn PHP because it is very widely used? Should I learn Objective-C because it is really wanted by employers now?

• Misadventures at Radio Shack

  - by Chris Williams

  While I'm waiting for my Arduino kits to show up, I started reading the Getting Started With Arduino book from O'Reilly (review coming later) and I'm about 40 pages in when I get to a parts list for one of the first projects. Looks pretty straightforward, and even has Radio Shack part numbers next to almost everything. So on my lunch today, I decided to run out to "The Shack" (seriously, that's their rebranding?) to pick up some basics, like a couple resistors, a breadboard, a momentary switch and a pack of pre-cut jumper wires. I found the resistors without any difficulty, and while they didn't have the exact switch I wanted, it was easy enough to find one that would do. That's where my good luck abruptly ended. I was surprised that I couldn't find a breadboard or any jumper wires, so while I was looking around, a guy came up and asked me if I needed some help. I told him I did, explained what I needed and even gave him the Radio Shack part number for the pack of jumper wires. After a couple minutes he says he can't find anything in the system, which was unfortunate but not the end of the world.  So then I asked him about the breadboard, and he pointed me to some blank circuitboards (which are not the same thing) and I said (nicely) that those weren't breadboards and attempted to explain (again) what I needed, at which point he says to me "I don't even know what the hell you're looking for!" I stood there for a moment and tried to process his words. About that time, another salesperson came up and asked what I was trying to find. I told her I needed a breadboard, and she pointed to the blank circuit boards and said "they're right in front of you..." After seeing the look on my face, she thought for a minute and said... "OH! you mean those white things. We don't have those anymore." I thanked her, set everything down on the counter and left. (I wasn't going to buy only half the stuff I needed.. and I was pretty sure I was never going to be buying ANYTHING at that particular location ever again.) Guess I'll be ordering more stuff online at this point. It's a shame really, because I used to LOVE going to Radio Shack as a kid, and looking through all the cool electronics components and stuff, even if I didnt understand what most of them were at the time. Seems like the only thing they carry in any quantity/variety now is cell phones and random stereo connectors.

• On the art of self-promotion

  - by Tony Davis

  I attended Brent Ozar’s Building the Fastest SQL Servers session at Tech Ed last week, and found myself engulfed in a ‘perfect storm’ of excellent technical and presentational skills coupled with an astute awareness of the value of promoting one’s work. I spend a lot of time at such events talking to developers and DBAs about the value of blogging and writing articles, and my impression is that some could benefit from a touch less modesty and a little more self-promotion. I sense a reticence in many would-be writers. Is what I have to say important enough? Haven’t far more qualified and established commentators, MVPs and so on, already said it? While it’s a good idea to pick reasonably fresh and interesting topics, it’s more important not to let such fears lead to writer’s block. In the eyes of any future employer, your published writing is an extension of your resume. They will not care that a certain MVP knows how to solve problem x, but they will be very interested to see that you have tackled that same problem, and solved it in your own way, and described the process in your own voice. In your current job, your writing is one of the ways you can express to your peers, and to the organization as a whole, the value of what you contribute. Many Developers and DBAs seem to rely on the idea that their work will speak for itself, and that their skill shines out from it. Unfortunately, this isn’t always true. Many Development DBAs, for example, will be painfully aware of the massive effort involved in tuning and adding resilience to rapidly developed applications. However, others in the organization who are unaware of what’s involved in getting an application that is ‘done’ ready for production may dismiss such efforts as fussiness or conservatism. At the dark end of the development cycle, chickens come home to roost, but their droppings tend to land on those trying to clear up the mess. My advice is this: next time you fix a bug or improve the resilience or performance of a database or application, make sure that you use team meetings, informal discussions and so on to ensure that people understand what the problem was and what you had to do to fix it. Use your blog to describe, generally, the process you adopted, the resources you used and the insights that came from your work. Encourage your colleagues to do the same. By spreading the art of self-promotion to everyone involved in an IT project, we get a better idea of the extent of the work and the value of the contribution of all the team members. As always, we’d love to hear what you think. This very week, Simple-talk launches its new blogging platform. If any of this has moved you to ‘throw your hat into the ring’, drop us a mail at [email protected]. Cheers, Tony.

• Recovering an Ubuntu installation - Ubuntu eats itself after 'sudo apt-get install -f'

  - by Tony Martin

  Updater (I assume) put a no entry style alert icon on the panel which informed me that certain package dependencies were not up to snuff. Upgrades were thereafter only partial. The dialogue advised that I sudo apt-get install -f. I did this hoping that app-get would fulfil dependencies and replace corrupted files and watched it systematically remove every component of linux, both the stuff I had installed and the core ubuntu packages. I could only assume at this stage that this was in preparation for a fresh install but, of course, I know better now - if you find yourself with apt-get warning you that you are about to remove several hundred packages and asking you to type an involved confirmation string seek advice before proceeding. I digress. This was a 64 bit install of 12.04. All that is left is grub pointing to a couple of windows recovery partitions on the hard drive. Thankfully the Ext4 partition is reachable from a stick boot. EDIT: I've logged onto the machine with a 64 bit stick and can see the file structure left behind by apt-get after {ahem} fixing. My first instinct was to run install from the stick but it seemed to want to do another install rather than a repair. My question then: is there a way to recover the current installation so that if I reinstall the packages I had they will pick up the original settings? I'm particularly worried about losing email from evolution - the rest I could probably lash back together. As for the use of PPA I'm not sure what you're driving at. I generally use Ubuntu Software Centre to install software, though I have used terminal scripts to add new repositories and software successfully following guidance on various websites. The most recent change I made was a downgrade of Wine in an attempt to install and run excel2007 (a necessity, I think, as I have VBA work to do). The installer had stalled and had to be killed. I wonder if that corrupted whatever database holds a model of the package installation structure. I would also be interested to know how this disaster came about. I see people in the know recommending the sudo apt-get install -f as a fairly innocuous cure in similar circumstances. Thanks for your attention, Tony Martin p.s. Do please forgive the rant aspects of the original post. It's hard to write rationally with a large hole in the pit of your stomach.

• Lubuntu wireless issue with Broadcom chipset

  - by Variant Web Solutions

  I'm a web dev that just started a new venture in buying wiped laptops in bulk and selling them at a low cost to lower income families that want a laptop that will simply preform and not become virus ridden and require constant maintenance, so naturally I opted for a linux distro and after some research, lubuntu was my top pick. I'm not a stranger to linux as all of my servers for my web dev business are linux, but I am however new to L/Ubuntu and I'm having some issues with both wifi (broadcom chipsets) on the 20 or so dells that I have right now, D800's, D810's and E5400's. Not sure if you can point me in a solid direction, I've scoured (and implemented) the suggestions on ask ubuntu and still coming up short. On one of the e5400's ( though they all seem to suffer the same errors) I got the following: [code]dell-latitude-e5400@dell-Latitude-E5400:~$ iwconfig lo no wireless extensions. eth0 no wireless extensions. dell-latitude-e5400@dell-Latitude-E5400:~$ lspci 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07) 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) 00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) 00:1a.0 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 (rev 02) 00:1a.1 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #5 (rev 02) 00:1a.2 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #6 (rev 02) 00:1a.7 USB controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #2 (rev 02) 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02) 00:1c.0 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 1 (rev 02) 00:1c.1 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 2 (rev 02) 00:1c.4 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 5 (rev 02) 00:1d.0 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #1 (rev 02) 00:1d.1 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2 (rev 02) 00:1d.2 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3 (rev 02) 00:1d.7 USB controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev 92) 00:1f.0 ISA bridge: Intel Corporation ICH9M LPC Interface Controller (rev 02) 00:1f.2 IDE interface: Intel Corporation 82801IBM/IEM (ICH9M/ICH9M-E) 2 port SATA Controller [IDE mode] (rev 02) 00:1f.3 SMBus: Intel Corporation 82801I (ICH9 Family) SMBus Controller (rev 02) 00:1f.5 IDE interface: Intel Corporation 82801IBM/IEM (ICH9M/ICH9M-E) 2 port SATA Controller [IDE mode] (rev 02) 02:01.0 CardBus bridge: Ricoh Co Ltd RL5c476 II (rev ba) 02:01.1 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller (rev 04) 02:01.2 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 21) 09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5761e Gigabit Ethernet PCIe (rev 10) dell-latitude-e5400@dell-Latitude-E5400:~$ rfkill Usage: rfkill [options] command Options: --version show version (0.5-1ubuntu1 (Ubuntu)) Commands: help event list [IDENTIFIER] block IDENTIFIER unblock IDENTIFIER where IDENTIFIER is the index no. of an rfkill switch or one of: all wifi wlan bluetooth uwb ultrawideband wimax wwan gps fm nfc dell-latitude-e5400@dell-Latitude-E5400:~$ [/code]

• Setting up port forwarding for 7000 appliance VM in VirtualBox

  - by uejio

  I've been using the 7000 appliance VM for a lot of testing lately and relied on others to set up the networking for the VM for me, but finally, I decided to take the dive and do it myself.  After some experimenting, I came up with a very brief number of steps to do this all using the VirtualBox CLI instead of the GUI. First download the VM image and unpack it somewhere.  I put it in /var/tmp. Then, set your VBOX_USER_HOME to some place with lots of disk space and import the VM: export VBOX_USER_HOME=/var/tmp/MyVirtualBoxVBoxManage import /var/tmp/simulator/vbox-2011.1.0.0.1.1.8/Sun\ ZFS\ Storage\ 7000.ovf (go get a cup of tea...) Then, set up port forwarding of the VM appliance BUI and shell:First set up port as NAT:VBoxManage modifyvm Sun_ZFS_Storage_7000 --nic1 nat Then set up rules for port forwarding (pick some unused port numbers):VBoxManage modifyvm Sun_ZFS_Storage_7000 --natpf1 "guestssh,tcp,,4622,,22"VBoxManage modifyvm Sun_ZFS_Storage_7000 --natpf1 "guestbui,tcp,,46215,,215" Verify the settings using:VBoxManage showvminfo Sun_ZFS_Storage_7000 | grep -i nic Start the appliance:$ VBoxHeadless --startvm Sun_ZFS_Storage_7000 & Connect to it using your favorite RDP client.  I use a Sun Ray, so I use the Sun Ray Windows Connector client: $ /opt/SUNWuttsc/bin/uttsc -g 800x600 -P <portnumber> <your-hostname> & The portnumber is displayed in the output of the --startvm command.(This did not work after I updated to VirtualBox 4.1.12, so maybe at this point, you need to use the VirtualBox GUI.) It takes a while to first bring up the VM, so please be patient. The longest time is in loading the smf service descriptions, but fortunately, that only needs to be done the first time the VM boots.  There is also a delay in just booting the appliance, so give it some time. Be sure to set the NIC rule on only one port and not all ports otherwise there will be a conflict in ports and it won't work. After going through the initial configuration screen, you can connect to it using ssh or your browser: ssh -p 45022 root@<your-host-name> https://<your-host-name>:45215 BTW, for the initial configuration, I only had to set the hostname and password.  The rest of the defaults were set by VirtualBox and seemed to work fine.

• My Automated NuGet Workflow

  - by Wes McClure

  When we develop libraries (whether internal or public), it helps to have a rapid ability to make changes and test them in a consuming application. Building Setup the library with automatic versioning and a nuspec Setup library assembly version to auto increment build and revision AssemblyInfo –> [assembly: AssemblyVersion("1.0.*")] This autoincrements build and revision based on time of build Major & Minor Major should be changed when you have breaking changes Minor should be changed once you have a solid new release During development I don’t increment these Create a nuspec, version this with the code nuspec - set version to <version>$version$</version> This uses the assembly’s version, which is auto-incrementing Make changes to code Run automated build (ruby/rake) run “rake nuget” nuget task builds nuget package and copies it to a local nuget feed I use an environment variable to point at this so I can change it on a machine level! The nuget command below assumes a nuspec is checked in called Library.nuspec next to the csproj file $projectSolution = 'src\\Library.sln' $nugetFeedPath = ENV["NuGetDevFeed"] msbuild :build => [:clean] do |msb| msb.properties :configuration => :Release msb.targets :Build msb.solution = $projectSolution end task :nuget => [:build] do sh "nuget pack src\\Library\\Library.csproj /OutputDirectory " + $nugetFeedPath end Setup the local nuget feed as a nuget package source (this is only required once per machine) Go to the consuming project Update the package Update-Package Library or Install-Package TLDR change library code run “rake nuget” run “Update-Package library” in the consuming application build/test! If you manually execute any of this process, especially copying files, you will find it a burden to develop the library and will find yourself dreading it, and even worse, making changes downstream instead of updating the shared library for everyone’s sake. Publishing Once you have a set of changes that you want to release, consider versioning and possibly increment the minor version if needed. Pick the package out of your local feed, and copy it to a public / shared feed! I have a script to do this where I can drop the package on a batch file Replace apikey with your nuget feed's apikey Take out the confirm(s) if you don't want them @ECHO off echo Upload %1? set /P anykey="Hit enter to continue " nuget push %1 apikey set /P anykey="Done " Note: helps to prune all the unnecessary versions during testing from your local feed once you are done and ready to publish TLDR consider version number run command to copy to public feed

• 3 Reasons You Need To Know Something About Every Technology

  - by Tim Murphy

  I make my living as a consultant and a general technologist.  I credit my success to the fact that I have never been afraid to pick up any product, language or platform needed to get the job done.  While Microsoft technologies I my mainstay, I have done work on mainframe and UNIX platforms and have worked with a wide variety of database engines.  Each one has it’s use and most times it is less expensive to find a way to communicate with an existing system than to replace it. So what are the main benefits of expending the effort to learn a new technology? New ways to solve problems Accelerate development Advise clients and get new business opportunities By new technology I mean ones that you haven’t had experience with before.  They don’t have to be the the one that just came out yesterday.  As they say, those who do not learn from history are bound to repeat it.  If you can learn something from an older technology it can be just as valuable as the shiny new one.  Either way, when you add another tool to your kit you get a new view on each problem you face.  This makes it easier to create a sound solution. The next thing you can learn from working with different products and techniques is how to more efficiently develop solve problems.  Many times if you are working with a new language you will find that there are specific design patterns that are used with it in normal use.  These can usually be applied with most languages.  You just needed to be exposed to them. The last point is about helping your clients and helping yourself.  If you can get in on technologies early you will have advantage over your competition in the market.  You will also be able to honestly advise you client on why they should or should not go with a new product.  Being able to compare products and their features is always an ability that stake holders appreciate. You don’t need to learn every detail of a product.  Learn enough to function and get an idea of how to use the technology.  Keep eating those technology Wheaties and you will be ready to go the distance in any project. del.icio.us Tags: Technology,technologists,technology generalist,Software Architecture

• Data structures for a 2D multi-layered and multi-region map?

  - by DevilWithin

  I am working on a 2D world editor and a world format subsequently. If I were to handle the game "world" being created just as a layered set of structures, either in top or side views, it would be considerably simple to do most things. But, since this editor is meant for 3rd parties, I have no clue how big worlds one will want to make and I need to keep in mind that eventually it will become simply too much to check, handling and comparing stuff that are happening completely away from the player position. I know the solution for this is to subdivide my world into sub regions and stream them on the fly, loading and unloading resources and other data. This way I know a virtually infinite game area is achievable. But, while I know theoretically what to do, I really have a few questions I'd hoped to get answered for some hints about the topic. The logic way to handle the regions is some kind of grid, would you pick evenly distributed blocks with equal sizes or would you let the user subdivide areas by taste with irregular sized rectangles? In case of even grids, would you use some kind of block/chunk neighbouring system to check when the player transposes the limit or just put all those in a simple array? Being a region a different data structure than its owner "game world", when streaming a region, would you deliver the objects to the parent structures and track them for unloading later, or retain the objects in each region for a more "hard-limit" approach? Introducing the subdivision approach to the project, and already having a multi layered scene graph structure on place, how would i make it support the new concept? Would you have the parent node have the layers as children, and replicate in each layer node, a node per region? Or the opposite, parent node owns all the regions possible, and each region has multiple layers as children? Or would you just put the region logic outside the graph completely(compatible with the first suggestion in Q.3) When I say virtually infinite worlds, I mean it of course under the contraints of the variable sizes and so on. Using float positions, a HUGE world can already be made. Do you think its sane to think beyond that? Because I think its ok to stick to this limit since it will never be reached so easily.. As for when to stream a region, I'm implementing it as a collection of watcher cameras, which the streaming system works with to know what to load/unload. The problem here is, i will be needing some kind of warps/teleports built in for my game, and there is a chance i will be teleporting a player to a unloaded region far away. How would you approach something like this? Is it sane to load any region to memory which can be teleported to by a warp within a radius from the player? Sorry for the huge question, any answers are helpful!

• Can working exclusively with niche apps or tech hurt your career in software development? How to get out of the cycle? [closed]

  - by Keoma

  I'm finding myself in a bit of a pickle. I've been at a pretty comfortable IT group for almost a decade. I got my start here working on web development, mostly CRUD, but have demonstrated the ability to figure out more complex problems. I'm not a rock star, but I have received many compliments on my programming aptitude, and technologists and architects have commented on my ability to pick things up (for example, I recently learned a very popular web framework that shall remain nameless since I don’t want to be identified). My problem is that, over time, my responsibilities have been shifting towards work such as support or ‘development’ with some rather niche products (afraid to mention here due to potential for being identified). Some of this work, if it includes anything resembling coding, is very menial scripting in languages such as Powershell or VBScript. The vast majority of the time, however, a typical day consists of going back and forth with the product’s vendor support to send them logs and apply configuration changes or patches they recommend. I’m basically starved for some actual software development. However, even though I’m more than capable of doing that development work (and actually do a much better job at it than anything else), our boss is more interested in the kind of work I mentioned above, her reasoning being that since no one else in the organization wants to do it, it must mean job security. This has been going on for close to 3 years, and the only reason I have held on is on the promise that we would eventually get more development projects assigned to us. Well, that turned out not to be true at all. A recent talk with the boss has just made it more explicitly clear, as she told me in no uncertain terms that it’s very likely that development work (web or otherwise) would go to another group. The reason given to me is that our we don’t have enough resources in our group to handle that. So now I find myself in the position that I either have to stay in what has essentially become a dead end IT job that is tied to the fortunes of a niche stack of apps, or try to find a position that will be better for my long term career. My problem (is it a problem?), however, is that compared to others, my development projects in the last three years are very sparse in number. To compound things, projects using the latest and most popular frameworks, amount to the big fat number of just one—with no work of that kind in the foreseeable future. I am very concerned that this sparseness in my resume is a deficit, and that it will hurt my chances of landing a different job. I’m also wondering how much it will hurt me, and whether that can be ameliorated with hobby projects of my own. I guess I’m looking for opinions. Thank you very much for reading.

• Writing or extending existing emacs packages: is it worth or should I move to Netbeans/Eclipse?

  - by Andrea

  I'm finishing my master degree course in CS and I've almost become addicted to Emacs. I've used it to write in C, Latex, Java, JSP,XML, CommonLisp, Ada and other languages no other editor supported, like AMPL. I'd like to improve the packages I've been using the most or create new ones, but, in practice, I find that the implementation of Emacs leaves a lot to be desired. There are a lot of poorly-featured/poorly-maintained packages with either overlapping functionalities or obscure incompatibilities, and Elisp just seems to foster the situation by lacking the common features modern lisps have. In contrast Eclipse and Netbeans are actively improved and it does seem they can be effective for non-mainstream languages. I tried Hibachi for Ada in Eclipse and it worked well, there's CUPS for Lisp in Eclipse and LambdaBeans built using NetBeans components. On the other hand those plugins seem to be less active than their Emacs' counterparts, for example Hibachi was archived last year. What's your opinion on this? Which editor should I write extension for? EDIT: To answer Larry Coleman (see comment below): I like Emacs as a user because it is efficient both for me and the computer I'm using. It's fast and the textual interface (i.e. minibuffer) allows for quick interaction. It's solid and packages are usually small and easy to manage. If I need to correct or remove something I usually just have to change a row in my .emacs or an elisp file, or delete a directory. Eclipse plugins rely on a more complicated process that screwed my Eclipse configuration a couple of times, forcing me to do a clean reinstall. Emacs works as long as I use the basic packages. If I need something more complicated the situation gets pretty hairy. As a "power user" I think that the best I can hope for is to write a severely crippled version of the extensions I'd actually like to have; in other words, that it's not worth the trouble. I'd like to write extensions for the things I'd like to have automated in Emacs, for example project support with automated tag-table update on file writing. There are a few projects on this that lack integration, documentation, extensibility and so forth. The best one is probably CEDET, for which I believe the Greenspun's 10th rule can be applied. EDIT: To comment Larry Coleman's answer I'm pretty sure I can pick elisp programming but the extensions I have in mind don't exist yet despite their relative simplicity and the effort more knowledgeable people poured into related projects.This makes me wonder whether it is so because of the way emacs is developed, i.e. people tend to write their own little extensions without coordination, or its implementation, its extension language not being able to keep up with the growing complexity.

• How employable am I as a programmer?

  - by dsimcha

  I'm currently a Ph.D. student in Biomedical Engineering with a concentration in computational biology and am starting to think about what I want to do after graduate school. I feel like I've accumulated a lot of programming skills while in grad school, but taken a very non-traditional path to learning all this stuff. I'm wondering whether I would have an easy time getting hired as a programmer and could fall back on that if I can't find a good job directly in my field, and if so whether I would qualify for a more prestigious position than "code monkey". Things I Have Going For Me Approximately 4 years of experience programming as part of my research. I believe I have a solid enough grasp of the fundamentals that I could pick up new languages and technologies pretty fast, and could demonstrate this in an interview. Good math and statistics skills. An extensive portfolio of open source work (and the knowledge that working on these projects implies): I wrote a statistics library in D, mostly from scratch. I wrote a parallelism library (parallel map, reduce, foreach, task parallelism, pipelining, etc.) that is currently in review for adoption by the D standard library. I wrote a 2D plotting library for D against the GTK Cairo backend. I currently use it for most of the figures I make for my research. I've contributed several major performance optimizations to the D garbage collector. (Most of these were low-hanging fruit, but it still shows my knowledge of low-level issues like memory management, pointers and bit twiddling.) I've contributed lots of miscellaneous bug fixes to the D standard library and could show the change logs to prove it. (This demonstrates my ability read other people's code.) Things I Have Going Against Me Most of my programming experience is in D and Python. I have very little to virtually no experience in the more established, "enterprise-y" languages like Java, C# and C++, though I have learned a decent amount about these languages from small, one-off projects and discussions about language design in the D community. In general I have absolutely no knowledge of "enterprise-y" technlogies. I've never used a framework before, possibly because most reusable code for scientific work and for D tends to call itself a "library" instead. I have virtually no formal computer science/software engineering training. Almost all of my knowledge comes from talking to programming geek friends, reading blogs, forums, StackOverflow, etc. I have zero professional experience with the official title of "developer", "software engineer", or something similar.

• Is it okay to have people with multiple roles in a Scrum team?

  - by Wayne M

  I'm evaluating some Agile-style methodologies for possible introduction to my team. With Scrum, is it allowable to have the same person perform multiple roles? We have a small team of four developers and a web designer; we don't really have a lead (I fulfill this role), QA testers or business analysts, and all of our development tasks come from the CIO. Automated testing is seen as a total waste of time, and everything focuses on speed and not quality. What will happen is the CIO will come up with a development task (whether a feature or a bug) and give it to a developer (not to the whole team, to an individual, often in private or out of the blue) who is then expected to get it completed. The CIO doesn't gather requirements beyond the initial idea (and this has bitten us before as we'll implement something only to find out that none of the end users can use the feature, because they weren't consulted or even informed about it before we developed it, and in a panic we'll be told to revert the change) but requires say in/approval of everything that we do. First things first, is a Scrum style something to consider to introduce some standards and practices? From reading, Scrum seems to rely on a bit more trust and communication and focuses more on project management than on development, which is something we are completely devoid of as we don't have any semblance of project management at present. Second, if it can work is it unreasonable for someone, let's say myself, to act as both ScrumMaster and a developer? Or for a developer to also be the Product Owner (although chances are this will be the CIO, who isn't a developer)? I realize the Scrum Master and the Product Owner should be different people but at the same time I don't think we have anyone who has the qualities of a Product Owner (chances are it would turn into a "I need all these stories, I don't care how but get it done" type of deal and/or any freeze would be unfrozen on a whim). It seems to me that I might need to pick and choose pieces of Scrum/XP/Lean to compensate for how things are done currently, as it's highly unlikely that the mentality can be changed; for instance Pair Programming would never fly (seen as a waste, you get half the tasks done if you need two people for everything), TDD would be a hard sell, but short cycles would be welcomed.

• On the art of self-promotion

  - by Tony Davis

  I attended Brent Ozar's Building the Fastest SQL Servers session at Tech Ed last week, and found myself engulfed in a 'perfect storm' of excellent technical and presentational skills coupled with an astute awareness of the value of promoting one's work. I spend a lot of time at such events talking to developers and DBAs about the value of blogging and writing articles, and my impression is that some could benefit from a touch less modesty and a little more self-promotion. I sense a reticence in many would-be writers. Is what I have to say important enough? Haven't far more qualified and established commentators, MVPs and so on, already said it? While it's a good idea to pick reasonably fresh and interesting topics, it's more important not to let such fears lead to writer's block. In the eyes of any future employer, your published writing is an extension of your resume. They will not care that a certain MVP knows how to solve problem x, but they will be very interested to see that you have tackled that same problem, and solved it in your own way, and described the process in your own voice. In your current job, your writing is one of the ways you can express to your peers, and to the organization as a whole, the value of what you contribute. Many Developers and DBAs seem to rely on the idea that their work will speak for itself, and that their skill shines out from it. Unfortunately, this isn't always true. Many Development DBAs, for example, will be painfully aware of the massive effort involved in tuning and adding resilience to rapidly developed applications. However, others in the organization who are unaware of what's involved in getting an application that is 'done' ready for production may dismiss such efforts as fussiness or conservatism. At the dark end of the development cycle, chickens come home to roost, but their droppings tend to land on those trying to clear up the mess. My advice is this: next time you fix a bug or improve the resilience or performance of a database or application, make sure that you use team meetings, informal discussions and so on to ensure that people understand what the problem was and what you had to do to fix it. Use your blog to describe, generally, the process you adopted, the resources you used and the insights that came from your work. Encourage your colleagues to do the same. By spreading the art of self-promotion to everyone involved in an IT project, we get a better idea of the extent of the work and the value of the contribution of all the team members. As always, we'd love to hear what you think. This very week, Simple-talk launches its new blogging platform. If any of this has moved you to 'throw your hat into the ring', drop us a mail at [email protected]. Cheers, Tony.

• Play the Microsoft Game “Are You Certifiable?”

  - by Mysticgeek

  Want to know if you have what it takes to be certified by Microsoft? Today we check out an enjoyable way to practice and test your IT knowledge of Microsoft products.  There are two modes, one where you log in with your Live account so you can save your progress, and play additional levels.   If you log in with your Live account, it’s obvious that Microsoft wants to sell you some certification courses, so just be aware of that. Or Guest Play where you can only play one episode and scores are not saved.   Playing the Game We’ll take a look at the Guest Play just so you get a sense of what the game is about. Enter in a username and pick an avatar… Then read the instructions…we won’t go over them all here, there are a lot of options and points are scored by correct answers, amount of time it takes to answer them, you get vouchers to play a question before answers are shown…etc. Once you start playing, you get certification questions, you can take as much time to read the question as you want, then hit the Answer button when you’re ready. Now you have four answers to choose from…notice the time clicking down, so you want to try to answer as quickly as possible. After selecting the answer, you’re told if it is correct or not, then given an answer explaination, along with your score. You can flag the topic so it comes up again, which is a good way to get repetition of various topics, which really helps when taking the cert tests. If you get an answer wrong, you still get an answer explanation which is cool, so you can learn and better understand the topic. Conclusion This game is definitely not for everyone, only those who are curious or want a fun way to practice for Microsoft certifications. If you are interested in a cert from Microsoft, it’s a fun way to practice up. Play Are You Certifiable?

• Self-Executing Anonymous Function vs Prototype

  - by Robotsushi

  In Javascript there are a few clearly prominent techniques for create and manage classes/namespaces in javascript. I am curious what situations warrant using one technique vs. the other. I want to pick one and stick with it moving forward. I write enterprise code that is maintained and shared across multiple teams, and I want to know what is the best practice when writing maintainable javascript ? I tend to prefer Self-Executing Anonymous Functions however I am curious what the community vote is on these techniques. Prototype : function obj() { } obj.prototype.test = function() { alert('Hello?'); }; var obj2 = new obj(); obj2.test(); Self-Closing Anonymous Function : //Self-Executing Anonymous Function (function( skillet, $, undefined ) { //Private Property var isHot = true; //Public Property skillet.ingredient = "Bacon Strips"; //Public Method skillet.fry = function() { var oliveOil; addItem( "\t\n Butter \n\t" ); addItem( oliveOil ); console.log( "Frying " + skillet.ingredient ); }; //Private Method function addItem( item ) { if ( item !== undefined ) { console.log( "Adding " + $.trim(item) ); } } }( window.skillet = window.skillet || {}, jQuery )); //Public Properties console.log( skillet.ingredient ); //Bacon Strips //Public Methods skillet.fry(); //Adding Butter & Fraying Bacon Strips //Adding a Public Property skillet.quantity = "12"; console.log( skillet.quantity ); //12 //Adding New Functionality to the Skillet (function( skillet, $, undefined ) { //Private Property var amountOfGrease = "1 Cup"; //Public Method skillet.toString = function() { console.log( skillet.quantity + " " + skillet.ingredient + " & " + amountOfGrease + " of Grease" ); console.log( isHot ? "Hot" : "Cold" ); }; }( window.skillet = window.skillet || {}, jQuery )); //end of skillet definition try { //12 Bacon Strips & 1 Cup of Grease skillet.toString(); //Throws Exception } catch( e ) { console.log( e.message ); //isHot is not defined } I feel that I should mention that the Self-Executing Anonymous Function is the pattern used by the jQuery team. Update When I asked this question I didn't truly see the importance of what I was trying to understand. The real issue at hand is whether or not to use new to create instances of your objects or to use patterns which do not require constructors of the use of the new keyword. I added my own answer, because in my opinion we should make use of patterns which don't use the new keyword. For more information please see my answer.

• Think Before You Leap - Life is Dangerous for Change Agents

  - by technodrone

  So you want to introduce agile methods to your team... The following are some "lessons learned" when from someone who advocated agile/scrum to a group that was not ready for it. "Change agents, in my experience, face negative consequences. Sometimes, most of the time at the beginning, it's painful. This is the question you might have to ask yourself. Do you want to be a developer in scrum project or do you want be a scrum master managing the process? I think with proper mentoring/training, you can become good scrum master. But is that what you want? if yes, you can go ahead, take the training. if you want to be a developer, you may not need to be certified  as scrum master. You can just pick up from a book such as Mike Cohn new book Succeeding with Agile, I am reading it now. It's good. In my experience, I did waste my resources by trying to change the culture. It cost me lot. Instead, I should have focused on technical practices that are core to agile. Then look for teams that are good at agile. I would have saved lot of energy, and time. Try baby steps first yourself in the company, and next with the team, starting with technical practices like writing unit tests, SOLID principles, patterns, refactoring, continuous integration, pairing, and peer code reviews. These have inherent pull that can bring collaboration from a team.  Once you see team adaption in core practices, then you can introduce scrum concepts like user stories/task board etc.  This idea of Leading by example seems to be working for most of the agile folks. You can pitch core practices to the manager, and the team, and start showing them how you are doing.  You can put a road map for agile adaption and you can pitch to your manager. I would include need for scrum master training as part of the road map. " I thought about his advice for a couple of weeks and read about the pitfalls of technical debt and the team not having prior awareness of agile methods. The more I read and think about it the more I think he was right.  What do you think?

• Speaker Notes...

  - by wulfers

  At a .Net User Group meeting this week, I experienced two poorly prepared speakers floundering through presentations….  As a Lead Technologist at the company I work for, I have experience training technical staff and also giving presentations at code camps.  Here are a few guidelines for aspiring speakers you might find helpful…   1.       Do not stand in front of your audience and read your slides.  This is  offensive to your audience and not what they came for...  Your slides are there to reinforce the information you are presenting and to give the audience a little clarification on some terms you may use and as a visual aid for some complicated issues. 2.       Have someone review your presentation (slides, notes, …) who speaks the language you will be presenting in fluently.  Also record at least ten minutes of your presentation and have that same person review that.  One of the speakers this week used the word “Basically” fifty times in less than thirty minutes…  I started to flinch every time he used the term. 3.       Be Prepared  -  before the presentation begins.  Don’t make any last minute changes to your presentation or demo code the night before.  Don’t patch your laptop or demo servers the night before.  If possible create a virtual image that you only use for presentations and use that (refreshed before every presentation). 4.       Know the level of expertise of your audience.  Speaking above or below their abilities will make or break your presentation. 5.       Deliver what you promise. The presentation this week was supposed to be on BDD (Behavior Driven Develpment).  The presenter completely ran off track and 90% of the discussion was how his team mistakenly used TDD (Test Driven Development), and was unhappy with the results.  Based on his loss of focus we only heard a rushed 10 minute presentation on DBB which was a disservice to the audience. 6.       Practice your presentation with your own small team before you try this on a room full of people you don’t know.  A side benefit of doing this with your own team is that you can get candid feedback from your team and also get kudos for training your own team.  I find I can also turn my presentations into technical white papers and get a third benefit from the work I’ve put into a presentation. 7.       Sharpen your own saw.  Pick a topic that is fairly current.  Something you would like to learn about and would benefit your current career path. 8.       Have fun doing it.

• Best Practices for serializing/persisting String Object Dictionary entities

  - by Mark Heath

  I'm noticing a trend towards using a dictionary of string to object (or sometimes string to string), instead of strongly typed objects. For example, the new Katana project makes heavy use of IDictionary<string,object>. This approach avoids the need to continually update your entity classes/DTOs and the database tables that persist them with new properties. It also avoids the need to create new derived entity types to support new types of entity, since the Dictionary is flexible enough to store any arbitrary properties. Here's a contrived example: class StorageDevice { public int Id { get; set; } public string Name { get; set; } } class NetworkShare : StorageDevice { public string Path { get; set; } public string LoginName { get; set; } public string Password { get; set; } } class CloudStorage : StorageDevice { public string ServerUri { get; set } public string ContainerName { get; set; } public int PortNumber { get; set; } public Guid ApiKey { get; set; } } versus: class StorageDevice { public IDictionary<string, object> Properties { get; set; } } Basically I'm on the lookout for any talks, books or articles on this approach, so I can pick up on any best practices / difficulties to avoid. Here's my main questions: Does this approach have a name? (only thing I've heard used so far is "self-describing objects") What are the best practices for persisting these dictionaries into a relational database? Especially the challenges of deserializing them successfully with strongly typed languages like C#. Does it change anything if some of the objects in the dictionary are themselves lists of strongly typed entities? Should a second dictionary be used if you want to temporarily store objects that are not to be persisted/serialized across a network, or should you use some kind of namespacing on the keys to indicate this?

• SQL Saturday 194 - Exeter

  - by Dave Ballantyne

  Many kudos goes to Jonathan and Annette Allen and the others on the team for confirming SQL Saturday 194 in Exeter on the 8th and 9th of March.  The event home page is here http://www.sqlsaturday.com/194/eventhome.aspx and I delighted that myself and Dave Morrison will be presenting a full day pre-con on the 8th on favourite subjects “TSQL and Internals”. Here is the full abstract : TSQL and internals - When faced with performance issues there are many lines of attack. Tuning the engine itself can get you so far, however for maximum effect you need to understand how the engine and how it translates SQL statements into performable actions. This is not a simple task, it is a massive task to deal with a multi-table join and the number of permutations can be immense. To back up this knowledge, we can create better performing TSQL and understand the impact that is has upon the engine and recognize the pitfalls and gotcha’s that exist in SQLServer. Ultimately, there is no ‘best way’ to perform a single task only many variations of ‘it depends’ , but now we can pick the most appropriate option for the required dataload. Over the years, there have been many myths and misconceptions have grown around the product, some have basis in older versions and some are just wrong. Continuing to build on the knowledge given so far these issue will be explored and broken down and proved or disproved. Finally we will look to the future and explore SQL Server 2012 and the new functionality that that brings and some of the common uses that we will be able to address. After completion of this days pre-con, attendees will have a more complete knowledge of execution plans, and how they relate to the physical and logical actions that SQLServer will be executing on their behalf. The attendees will also have a more rounded and fuller knowledge of TSQL and the implications of incorrectly defining a query. Dave is a fountain of knowledge on execution plans and optimizer internals and ,though i may flatter myself, I’m no shrinking violet when it comes to TSQL and such matters.  I hope that if you cant join us, then there are other pre-cons available from other experts in their fields that may ‘float you boat’ too.  The pre-con page is http://sqlsouthwest.co.uk/SQLSaturday_precon.htm Also, excitingly, this pre-con day is sponsored by Fusion-IO which is a great boon for the day. If you want a more of this then i am offering a 2 day TSQL course starting on the 19th of March. More details on this are available here

• How to send multiple MVP matrices to a vertex shader in OpenGL ES 2.0

  - by Carbon Crystal

  I'm working my way through optimizing the rendering of sprites in a 2D game using OpenGL ES and I've hit the limit of my knowledge when it comes to GLSL and vertex shaders. I have two large float buffers containing my vertex coordinates and texture coordinates (eventually this will be one buffer) for multiple sprites in order to perform a single glDrawArrays call. This works but I've hit a snag when it comes to passing the transformation matrix into the vertex shader. My shader code is: uniform mat4 u_MVPMatrix; attribute vec4 a_Position; attribute vec2 a_TexCoordinate; varying vec2 v_TexCoordinate; void main() { v_TexCoordinate = a_TexCoordinate; gl_Position = u_MVPMatrix * a_Position; } In Java (Android) I am using a FloatBuffer to store the vertex/texture data and this is provided to the shader like so: mGlEs20.glVertexAttribPointer(mVertexHandle, Globals.GL_POSITION_VERTEX_COUNT, GLES20.GL_FLOAT, false, 0, mVertexCoordinates); mGlEs20.glVertexAttribPointer(mTextureCoordinateHandle, Globals.GL_TEXTURE_VERTEX_COUNT, GLES20.GL_FLOAT, false, 0, mTextureCoordinates); (The Globals.GL_POSITION_VERTEX_COUNT etc are just integers with the value of 2 right now) And I'm passing the MVP (Model/View/Projection) matrix buffer like this: GLES20.glUniformMatrix4fv(mMVPMatrixHandle, 1, false, mModelCoordinates); (mModelCoordinates is a FloatBuffer containing 16-float sequences representing the MVP matrix for each sprite) This renders my scene but all the sprites share the same transformation, so it's obviously only picking the first 16 elements from the buffer which makes sense since I am passing in "1" as the second parameter. The documentation for this method says: "This should be 1 if the targeted uniform variable is not an array of matrices, and 1 or more if it is an array of matrices." So I tried modifying the shader with a fixed size array large enough to accomodate most of my scenarios: uniform mat4 u_MVPMatrix[1000]; But this lead to an error in the shader: cannot convert from 'uniform array of 4X4 matrix of float' to 'Position 4-component vector of float' This just seems wrong anyway as it's not clear to me how the shader would know when to transition to the next matrix anyway. Anyone have an idea how I can get my shader to pick up a different MVP matrix (i.e. the NEXT 16 floats) from my MVP buffer for every 4 vertices it encounters? (I am using GL_TRIANGLE_STRIP so each sprite has 4 vertices). Thanks!

• Does the Ubuntu One sync work?

  - by bisi

  I have been on this for several hours now, trying to get a simple second folder to sync with my (paid) account. I cannot tell you how many times I removed all devices, removed stored passwords, killed all processes of u1, logged out and back in online...and still, the tick in the file browser (Synchronize this folder) is loading and loading and loading. Also, I have logged out, rebooted countless times. And this is after me somehow managing to get the u1 preferences to finally "connect" again. I have also checked the status of your services, and none are close to what I am experiencing. And I have checked the suggested related questions above! So please, just confirm whether it is a problem on my side, or a problem on your side. EDIT: In the mean time, here is what has changed, on top of what is mentioned just above. • My files went from 0MB to 71.9MB, and is still rising. • My first folder of 400.2MB is being filled with the data as I write this. The second folder has the folder sub-structure in place. • Both folders now show in the File Browser that it will be synchronized. I believe that right now, it is all back to normal and working fine, and I guess that's what a good night's sleep can do ;). And we're now only back to the point where synchronizing is slow, but will pick up with the release of Natty (https://wiki.ubuntu.com/UbuntuOne/FAQ/WhyIsItTakingSoLongForMyFilesToSync). But to get to the questions: My about says I use 11.04, Natty Narwhal, but I am quite sure the last distribution I installed was 10.10. Folder A is 400.2MB, and Folder B is 29.5MB I am on a DSL line, behind a regular fritz.box setting. No proxy servers in use, and I did not install any particular firewall features. No physical firewall, just the router (on which I have a TV signal as well), and 2 switches to get to this floor. Status: inactive The ubuntuone-indicator runs the same window as when I click on my name on the top-right corner and select Ubuntu one, or in the Control Center choose Ubuntu one. It wasn't supposed to go further than this was it?
