  • Chargeback and showback...both a 'throw back'

    - by llaszews
    Been getting asked again by customers and partners about chargeback and showback in the cloud so thought I would blog on my response to this question. Charge Back background, information and industry analysis: Cloud computing is all about shared resources. These shared resources are computer servers (including memory and CPU), network devices, hard disk storage, database servers, application servers, cooling, floor space, electricity and more. These resources are shared by departments within a company, or by a number of companies, when resources are hosted in the public or hybrid cloud. Currently, hosting providers that run other companies on their cloud platforms do not have an accurate way to measure the shared computing resources used by a specific user let alone used by a specific customer. Additionally, companies running their own cloud data centers, for private or hybrid clouds, have no way of measure and charging back the departments in the company that are using these shared cloud resources. In both cases, the lack of determine shared resource costs and to charge them back to the company, department or user that is using this resources is limited a clear measure of business benefit and impacting company’s ability to measure the Return on Investment (ROI). An IT chargeback system is an accounting strategy that applies the costs of IT services, hardware or software to the business unit in which they are used. This system contrasts with traditional IT accounting models in which a centralized department bears all of the IT costs in an organization and those costs are treated simply as corporate overhead. Showback involves showing the IT costs to a department or customer but not actually charging them for their IT usage. Showback is a gradual method of introducing chargeback into an enterprise. Most companies implement a show back mechanism before a full chargeback system is put in place. Oracle chargeback product: Oracle Enterprise Manager provides tools for defining detailed Chargeback plans spanning different metrics collected for each type of resources as well as defining Cost Centers for grouping costs across multiple developers. Chargeback plans can use not only usage based costs, but also configuration based costs (e.g. version of the platform) or fixed costs (e.g. flat-rate management fee). Chargeback has rich out of the box reports. Trending reports show how charge and resource consumption varies over time, while Summary reports show the breakdown of charges or usage by different dimensions such as Cost Center or Target Type. These reports help consumers in understanding how their charges relate to their consumption and also assist the IT department with budgeting and planning activities. With BI Publisher, the reports can be made available in a variety of formats such as PDF, HTML, Word, Excel or PowerPoint.

  • Getting Started with Kinect for Windows.

    - by Vishal
    Hello folks,      Recently I got involved in a project for building a demo application for one of our customers with Kinect for Windows. Yes, something similar what Tom Cruise did in the movie Minority Report. Waving arms, moving stuff around, swipes, speech recognition, manipulating computer screens without even touching it. Pretty cool!!! The idea in the movie showed us how technology would be after 50 years from that day.   Minority Report Movie clip.           Well, that 50 years of time frame got squeezed and recently on Feb 1st 2012, Microsoft released the official Kinect for Windows SDK. That’s just 10 years from the movie release. Although, the product is in it early stages but with developer creativity and continuously improving hardware, those features shown in the movie are not very far away from becoming a reality. Soon after releasing the SDK, Microsoft again announced in March the release of its new Kinect for Windows SDK version 1.5 which is coming out in sometime May. More history about Kinect. Anyways, so for a newbie with Kinect, where would you start. Here is what I would suggest you can do. Watch the Kinect for Windows Quick start Series by Den Fernandez. Download the Kinect for Windows SDK and start playing around with the demos in it. It also comes with some basic Kinect documentation. Coding4Fun Kinect Projects | Lot many more videos and open sources projects information. Kinect for Windows Session at Techdays NL demo by Jesus Rodriguez. Book: Beginning Kinect Programming with the Microsoft Kinect SDK.  | I did go through few of the chapters in this book and based on that, it does talk deeply about core Kinect concepts but in very easy to understand way. I would definitely suggest this book for any Kinect developers. I liked the way it explained the Gestures recognition in Chapter 6. Buy your Kinect device from either Amazon or NewEgg. You will get it cheaper then buying it from Microsoft Store. Personally, I love Newegg.com as I never had any order related or shipping issues with them. I always hate developing UI application but well, you would need to get your hands dirty with WPF too in order to work with Kinect. So get started with WPF concepts too. I will keep adding stuff to the list once I come across them but so far the above list would definitely get you started building your first Kinect apps. Till then Happy Kinecting…!!!!! Thanks, Vishal Mody

  • viable part-time career in IT/programming?

    - by Rider
    Hi, I'd like to ask for some career advice from you people. Is there a viable job/career that can be done in programming/IT for the long term? Right now, I am thinking about website (PHP?) developer path. My background: I have a degree in computer science and have been a programmer/system analyst for almost 10 years. Lately I took a big break from programming and studied for a B.arch. degree (yes architecture), only to discover that architecture offers zero (0) jobs where I'm from, for 3 years already (and no, I am not going to move and the grass in not greener in other places). I have never been particularly interested in programming, in fact I was bored by it. But I was always quite good at both programming and system analysis, and very valued by practically all my employers. On the other hand, I have never been valued or offered a good job in any other field (although I can do many things, like design, architecture, translations, documentation, teaching, etc etc.) I guess the human component has been always more important for me in programming jobs - I value all the good people I worked with, but not projects. However, I have about zero skills or desire to be a project manager. I also have close to zero skills for selling myself. I like it best when I can do "my thing", have my niche, have an ownership of some project. Right now my career perspective is to do part time programming and to part time teach yoga. I have already started the yoga teaching part. Do you think that part time programming is viable? And what niche works best for that? I have considered web development, QA, or software development in a company like I did before. However, my fear is that when you do programming part-time, you get the most boring coding work, only to see your colleagues move to more interesting projects and up their respective career ladders. I also fear that part-timers are not especially needed either. And, since I don't share much enthusiasm at programming, I'd rather not be around young programmers boiling with geeky enthusiasm about coding, but rather QA mindset with people from different backgrounds and life paths might work better for me. Thanks for any advice, --Rider

  • The Case for Complimentary Software Copies

    - by GGBlogger
    As the Geriatric Geek you can understand that I’ve been writing and studying for over 60 years. That means that I’ve seen insane changes in the computer software industry. I’ve made the joke that I get a new college education every 6 months or so. Of course that’s an exaggeration but it doesn’t make the feeling go away. I have a long standing and strong relationship with Microsoft so I’m armed with virtually every tool they make. It also means that I have access to tons of training material. But here’s the rub… Last year I started a definitive read of Professional Visual Basic 2008. The purpose was to fill in holes in my understanding of various things. I’m currently on page 1119 of some 1400 pages. During this sojourn I’ve decided that the future is web related which is to say that the future of “thick client” applications running as Windows applications is likely to slowly disappear. To that end I’ve taken a side trip or two into the world of ASP (including XML), Silverlight and cloud development. After carefully avoiding (that’s tongue in cheek) XML for years I finally had to bite the bullet, so to speak, and start learning XML in earnest. The most recent result of that was trail downloads of Altova’s MissionKit 2010 for Software Architects and Liquid Technologies Liquid XML Studio Developer Edition. These are both beautiful products and I want to learn them and write about them. Now comes the rub… While 30 day evaluations are generous in allowing casual users to assess these technologies for purchase they are NOT long enough to allow an author to evaluate, learn and ultimately write about them. Even if I devoted the full 30 days to learning, using and writing about say Altova’s suite I wouldn’t have enough time. Liquid XML may be a little easier to learn (one product as opposed to 8).  Add to that the fact that I frequently get sidetracked to add to my kit and it really blows out. It can be extremely frustrating when I’ve devoted hours to a project and suddenly discover that to complete it I will either need to purchase a license or abandon the project. Since my life blood does not depend on the product I end up abandoning the project and moving on. So to the folks from whom I request complimentary copies… I guarantee that if I convert your product to doing paid development work I will purchase a license to do that but as long as I am using your product to study for the purpose of writing samples, teaching use or otherwise promoting your product to other paying customers I will ask that you give me a license so that I can do that without facing the dread expiration of a 30 day trial.

I have also used this same computer for internet access when I had Ubuntu Desktop installed so internet does work.

  • SCCM 2007 Collections per OU

    - by VirtualizeIT
    Recently I wanted to create our SCCM collections setup as our Active Directory structure. I finally figured out how to create collections per OU of the domain. I decided to create a simple tutorial that may help other IT professionals the steps to complete this task.   1. Open the ConfigMgr and navigation to the collections. To navigate to the collections go to Site Database>Computer Management>Collections. 2. In the ‘Collections’ right-click and select New Collections. Then it will pop up a Wizards so you can enter the name of the collection and any notes that you may want to add that is associated with the collection.                       3. Next, select the database icon. In the ‘Name’ textbox enter the name of the query. I named mine ‘Query’ just for simplicity sake. After you enter the name select ‘Edit Query Statement…’ 4. Select the ‘Criteria’ tab 5. Select the icon that looks like a sun. 6. At this point you should see a dialog box like this…                     7. Next, click the ‘select’ button. 8. Under the ‘Attribute class’ scroll through until you see ’System Resource’ and for the ‘Attribute"’ scroll through you see ‘System OU Name’. It should look something like this…                 9. After that select OK. 10. In the ‘Value’ textbox enter the string that is associated with the OU in your domain. NOTE: If you don’t know your string name for your OU you can simply go to “Active Directory Users and Computers” and right-click on the OU and select properties. In the ‘object’ tab you should see the string under the ‘Canonical name of object”. That is the string that you put in the ‘Value’ text box. 11. After you enter the OU string name press OK>OK>OK>NEXT>NEXT>FINISH.   That’s it!   I hope this tutorial has help you understand how to create a collection through your OU structure.

  • Memory Glutton

    - by AreYouSerious
    I have to admit that I can't get enough storage. I have hard drives just sitting around in case I need to move somthing, or I'm going to a friends and either they want something I have or I want something they might have. What I'm going to talk about today is cost effective memory for devices. I don't know how this particualr device will work in a camera, as That's not what I use in my camera, in fact I don't have a camera that doesn't either use SD, or the old compact flash card, that's not so compact anymore. There's this thing that uses two micro sd cards to double the capacity of your memory, and it costs about 4 bucks, without the Micro SD card. I have had one for about a year and was going to throw it away because I couldn't get it to work with my computer, or with my Sony Reader. However I found out by one last ditch effort that this thing works beautifully with my Sony PSP. there is no software to speak of associated with this thing, you simply put in two SD cards of the same size... (if you put in two different sizes it will still work, you'll only double the smallest cards size though) and format through the psp. Viola you know have a 29 GB memory card for your PSP. why is this important ? well for starters you can carry more music and more videos. Second if you have gone the way of the hacker.... you can store more games on your card... There are just a few things you have to note.... I speak from experience... you have to use the usb connection to the PSP to do any file moving, as I said previously said card doesn't play well with my computers or card readers... I not saying it won't work at all, just hasn't work with anything I own. Second. If for some reason you try to Hack/crack your PSP don't attempt to delete a game from the psp, use the usb file browser to remove games. if you delete from the PSP you are likely to have to move all your files off, reformat and start again... just a couple things I have noticed... if I had done something like that.   anyway, Here's a link.... http://www.photofast-adapter.com/  and if you want to buy one, get it off ebay, I've seen them as low as $1.99

  • How do I stop icons appearing on the desktop in a particular area?

    - by Seamus
    When I download something to my desktop, or insert a CD or flash drive, the icon appears on my desktop. When I have conky running, the icon sometimes appears in the top right corner, underneath conky; where I can't see it. How do I stop this happening? My .conkyrc is pasted below.

  • How to fix 'grub error file not found' when installing 12.04?

    - by Tomasz Grabowski
    i'm trying to install Ubuntu. I don't know if it is important, but i'm trying to install it on external HDD. In the end i have external bootable HDD which only displays: error: file not found grub recovery> From the beginning: I've downloaded ubuntu-12.04-desktop-i386.iso I've used LiLi USB Creator (LinuxLive) to create bootable pendrive from that image I've bootet from it, it works I've clicked "Try ubuntu", it works too. I've used GParted to look over drivers (disks) My primary embedded disk is seen as /dev/sda My attached external disk as /dev/sdb My PenDrive as /dev/sdc I've created partitions on /dev/sdb Fist partition for system (over 200GiB) Second was there already (it's xsf, and i don't want to touch it :P) Third is extended partition, with 1 locital partiton (10GiB) for swap I've started installation i've choose "somethin else" in ... i belive secound screeb then is selected /dev/sdb as boot disk for first partiton of /dev/sdb i set i want ext3 file system, i've check "formattin" checkbox, and mount path set to "/" firs logical partiton set as swap partition After installation finished, i restarted my computer. When i boot from my primary disc it's work ok, my previous operating system - vista - works ok. When i set my BIOS to boot from my external disc, i only get that message: error: file not found grub recovery> I've try to reinstall it, but didn't help... In desperation, i've try to read a bit about that "grub recovery" command-line and experiment a bit... I'm not sure if this has had any point, or if it give you some information (notice, that i don't know what i'm doing :P ) when i've type command: insmod (hd1,1)/boot/grub/linux.mod i've get message: unknown filesystem the same with: insmod (hd1,msdos1)/boot/grub/linux.mod the same with: insmod ext3 but i get no message after command: insmod ext2 ... notice that i really don't know what this command exactly do, but than i thought that maybe if i reinstall ubuntu with ext2 filesystem, it will work. I've done that, but symptoms are the same. I've go back to that Live version of ubuntu, filesystem and basics directories seems to be present on /dev/sdb1 ... i'm completely unfamiliar with GRUB. I'm also don't know which wersion of GRUB it is, i hope there is only one version on ubuntu-12.04-desktop-i386.iso Any help? Thax

  • Ubuntu systematically losing wired connection

    - by Lukasz Baczynski
    I'm working on 11.10 for few recent days, everything was working perfect until today. Updated ubuntu (some certs were updates as far as i remember) and from this time, wired network stops working randomly and systematically.

  • GPU hung when switching graphic card

    - by Lie Ryan
    I have a laptop (Dell Inspiron N4110) with a switchable graphic. $ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: ATI Technologies Inc NI Whistler [AMD Radeon HD 6600M Series] (rev ff) Normally, my laptop starts with both graphic cards enabled, which caused the laptop to turn very hot and the fan to become very noisy. I have been using a small script to disable the Radeon card. For some time, I'm quite happy with this arrangement. However, I have been having some issues with the Intel card (IGD), the Intel card often randomly hang when running OpenGL apps; and so I want to give the Radeon card (DIS) another chance. I have never been able to switch to the Radeon card, but recently, I found out that if I do a "delayed switching" (DDIS): # echo "DDIS" > /sys/kernel/debug/vgaswitcheroo/switch root@lieryan-dell-ubuntu:/sys/kernel/debug/vgaswitcheroo# cat switch 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :Pwr:0000:01:00.0 then I logoff (i.e. to restart X), the screen switch to pseudo-tty and then it stuck there freezing. At this situation, mouse and keyboard stops working so I can't switch to another ptty. I tried ssh-ing from another computer to salvage logs (dmesg at that point) and whatnot; I found out that when freezing, the active graphic card is the AMD card: -- this is from ssh -- # cat switch 0:IGD: :Off:0000:00:02.0 1:DIS:+:Pwr:0000:01:00.0 but the GPU is apparently hung, looking at dmesg gives: ...

I were able to successfully recover by switching back to the Intel card and restarting X from ssh; indicating that only the Radeon card has problems switching. System info: $ uname -a Linux lieryan-dell-ubuntu 3.0.0-14-generic #23-Ubuntu SMP Mon Nov 21 20:28:43 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 11.10 Release: 11.10 Codename: oneiric The laptop also do not have the option to set graphic card at BIOS and the proprietary driver, fglrx, also have never worked; when I installed it through jockey ("Additional Drivers"), glxinfo showed that it still being rendered by Mesa, the /sys/kernel/debug/vgaswitcheroo directory has gone missing, and the driver crashes with a traceback if I use xorg.conf to tell X to use fglrx. Anyone had any idea if it is possible to use this AMD card either with the radeon or the fglrx driver? logs: dmesg

  • Developer – Cross-Platform: Fact or Fiction?

    - by Pinal Dave
    This is a guest blog post by Jeff McVeigh. Jeff McVeigh is the general manager of Performance Client and Visual Computing within Intel’s Developer Products Division. His team is responsible for the development and delivery of leading software products for performance-centric application developers spanning Android*, Windows*, and OS* X operating systems. During his 17-year career at Intel, Jeff has held various technical and management positions in the fields of media, graphics, and validation. He also served as the technical assistant to Intel’s CTO. He holds 20 patents and a Ph.D. in electrical and computer engineering from Carnegie Mellon University. It’s not a homogenous world. We all know it. I have a Windows* desktop, a MacBook Air*, an Android phone, and my kids are 100% Apple. We used to have 2.5 kids, now we have 2.5 devices. And we all agree that diversity is great, unless you’re a developer trying to prioritize the limited hours in the day. Then it’s a series of trade-offs. Do we become brand loyalists for Google or Apple or Microsoft? Do we specialize on phones and tablets or still consider the 300M+ PC shipments a year when we make our decisions on where to spend our time and resources? We weigh the platform options, monetization opportunities, APIs, and distribution models. Too often, I see developers choose one platform, or write to the lowest common denominator, which limits their reach and market success. But who wants to be ?me too”? Cross-platform coding is possible in some environments, for some applications, for some level of innovation—but it’s not all-inclusive, yet. There are some tricks of the trade to develop cross-platform, including using languages and environments that ?run everywhere.” HTML5 is today’s answer for web-enabled platforms. However, it’s not a panacea, especially if your app requires the ultimate performance or native UI look and feel. There are other cross-platform frameworks that address the presentation layer of your application. But for those apps that have a preponderance of native code (e.g., highly-tuned C/C++ loops), there aren’t tons of solutions today to help with code reuse across these platforms using consistent tools and libraries. As we move forward with interim solutions, they’ll improve and become more robust, based, in no small part, on our input. What’s your answer to the cross-platform challenge? Are you fully invested in HTML5 now? What are your barriers? What’s your vision to navigate the cross-platform landscape?  Here is the link where you can head next and learn more about how to answer the questions I have asked: https://software.intel.com/en-us Republished with permission from here.

  • Setting up Ubuntu Server as a Router with DHCPD and 3 Ethernet devices

    - by cengbrecht
    My configuration: Ubuntu 12.04 DHCP3-server eth0, eth1, eth2 Edit: removed br0&br1 eth0 is the external connection eth1 & eth2 are the internal network eth1 and eth2 are supposed to be seperate networks of student/teachers respectivly. What I would like to have is the internet from external device bridged to device 1 and 2, with the DHCP server controlling the two internal devices. Its already working with DHCP, the part I am stuck on is bridging for internet. I have setup a script that I found here: Router With the original script he linked here: Ubuntu Router Guide echo -e "\n\nLoading simple rc.firewall-iptables version $FWVER..\n" IPTABLES=/sbin/iptables #IPTABLES=/usr/local/sbin/iptables DEPMOD=/sbin/depmod MODPROBE=/sbin/modprobe EXTIF="eth0" INTIF="eth1" INTIF2="eth2" echo " External Interface: $EXTIF" echo " Internal Interface: $INTIF" echo " Internal Interface: $INTIF2" EXTIP=`ifconfig $EXTIF | grep 'inet addr:' | sed 's#.*inet addr\:\([0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\).*#\1#g'` echo " External IP: $EXTIP" #====================================================================== #== No editing beyond this line is required for initial MASQ testing == The rest of the script below this is as is. I can get ip from the eth1 & eth2 devices, and my computer can see them, and them it, however, internet is not being passed through. If you need more information please just let me know. EDIT: So I had a 255.255.254.0 network, I believe that was causing the issue. Not sure if it will matter on the second card, I will test later. After changing the subnet to 255.255.255.0 the pings will pass through, however, I cannot get DNS requests to pass?

  • Puppet: Getting Started On Windows

    - by Robz / Fervent Coder
    Originally posted on: http://geekswithblogs.net/robz/archive/2014/08/07/puppet-getting-started-on-windows.aspxNow that we’ve talked a little about Puppet. Let’s see how easy it is to get started. Install Puppet Let’s get Puppet Installed. There are two ways to do that: With Chocolatey: Open an administrative/elevated command shell and type: choco install puppet Download and install Puppet manually - http://puppetlabs.com/misc/download-options Run Puppet Let’s make pasting into a console window work with Control + V (like it should): choco install wincommandpaste If you have a cmd.exe command shell open, (and chocolatey installed) type: RefreshEnv The previous command will refresh your environment variables, ala Chocolatey v0.9.8.24+. If you were running PowerShell, there isn’t yet a refreshenv for you (one is coming though!). If you have to restart your CLI (command line interface) session or you installed Puppet manually open an administrative/elevated command shell and type: puppet resource user Output should look similar to a few of these: user { 'Administrator': ensure => 'present', comment => 'Built-in account for administering the computer/domain', groups => ['Administrators'], uid => 'S-1-5-21-some-numbers-yo-500', } Let's create a user: puppet apply -e "user {'bobbytables_123': ensure => present, groups => ['Users'], }" Relevant output should look like: Notice: /Stage[main]/Main/User[bobbytables_123]/ensure: created Run the 'puppet resource user' command again. Note the user we created is there! Let’s clean up after ourselves and remove that user we just created: puppet apply -e "user {'bobbytables_123': ensure => absent, }" Relevant output should look like: Notice: /Stage[main]/Main/User[bobbytables_123]/ensure: removed Run the 'puppet resource user' command one last time. Note we just removed a user! Conclusion You just did some configuration management /system administration. Welcome to the new world of awesome! Puppet is super easy to get started with. This is a taste so you can start seeing the power of automation and where you can go with it. We haven’t talked about resources, manifests (scripts), best practices and all of that yet. Next we are going to start to get into more extensive things with Puppet. Next time we’ll walk through getting a Vagrant environment up and running. That way we can do some crazier stuff and when we are done, we can just clean it up quickly.

  • Software monetization that is not evil

    - by t0x1n
    I have a free open-source project with around 800K downloads to date. I've been contacted by some monetization companies from time to time and turned them down, since I didn't want toolbar malware associated with my software. I was wondering however, is there a non-evil way to monetize software ? Here are the options as I know them: Add a donation button. I don't feel comfortable with that as I really don't need "donations" - I'm paid quite well. Donating users may feel entitled to support etc. (see the second to last bullet) Add ads inside your application. In the web that may be acceptable, but in a desktop program it looks incredibly lame. Charge a small amount for each download. This model works well in the mobile world, but I suspect no one will go for it on the desktop. It doesn't mix well with open source, though I suppose I could charge only for the binaries (most users won't go to the hassle of compiling the sources). People may expect support etc. after having explicitly paid (see next bullet). Make money off a service / community / support associated with the program. This is one route I definitely don't want to take, I don't want any sort of hassle beyond coding. I assure you, the program is top notch (albeit simple) and I'm not aware of any bugs as of yet (there are support forums and blog comments where users may report them). It is also very simple, documented, and discoverable so I do think I have a case for supplying it "as is". Add affiliate suggestions to your installer. If you use a monetization company, you lose control over what they propose. Unless you can establish some sort of strong trust with the company to supply quality suggestions (I sincerely doubt it), I can't have that. Choosing your own affiliate (e.g. directly suggesting Google Toolbar) is possibly the only viable solution to my mind. Problem is, where do I find a solid affiliate that could actually give value to the user rather than infect his computer with crapware? I thought maybe Babylon (not the toolbar of course, I hate toolbars)?

  • Investing in Servers by Intel

    - by Koushal Deshpande
    Originally posted on: http://geekswithblogs.net/BizTalkAndOtherTechs/archive/2013/10/31/investing-in-servers-by-intel.aspxA nice article reference from Intel, refer here. Referees to cloud as well. Choose correctly what you need. 1 Do determine right server for your company. There is no use getting a server that has redundant services but still add to the costs. 2 Do get servers that can be upgraded. A server with limited memory and storage may not be able to keep up with your business growth. The basic memory and storage options might not be sufficient. Consider at least 8GB of RAM and 1 terabyte of hard disk space. 3 Do check the server has at least one Gigabit Ethernet port. This allows high speed transferring of files and increases productivity for your employees. USB and Firewire ports may not be enough as their transfer speed is too low and will affect the productivity of your company. Infinite Technologies is ready to help perform this upgrade. Contact Infinite Technologies now View our other resellers » 4 Do verify that the server comes with documentation. Documentation allows you to make a claim when your server breaks down and is supported by a warranty. 6 Do check the support options for the server from the manufacturer. Different manufacturer has different support options such as maintenance plans and software upgrades. 5 Do always look into the warranty. Get an enhanced warranty that guarantees response and repair time to avoid disruption. 7 Do get server management tools that can be used on any computer. Server management tools should be cross compatible across different operating systems to take into account future PC replacements. 8 Do check the power usage of the servers. Get the right power supply to avoid damaging server hardware and consider the Intel® Xeon® E3 processor to help save on your electricity bills. 9 Do check what built-in security packages are available. Ensure that your server is protected. Built-in security1 helps you save on getting add on security packages.

  • How can a solo programmer become a good team player?

    - by Nick
    I've been programming (obsessively) since I was 12. I am fairly knowledgeable across the spectrum of languages out there, from assembly, to C++, to Javascript, to Haskell, Lisp, and Qi. But all of my projects have been by myself. I got my degree in chemical engineering, not CS or computer engineering, but for the first time this fall I'll be working on a large programming project with other people, and I have no clue how to prepare. I've been using Windows all of my life, but this project is going to be very unix-y, so I purchased a Mac recently in the hopes of familiarizing myself with the environment. I was fortunate to participate in a hackathon with some friends this past year -- both CS majors -- and excitingly enough, we won. But I realized as I worked with them that their workflow was very different from mine. They used Git for version control. I had never used it at the time, but I've since learned all that I can about it. They also used a lot of frameworks and libraries. I had to learn what Rails was pretty much overnight for the hackathon (on the other hand, they didn't know what lexical scoping or closures were). All of our code worked well, but they didn't understand mine, and I didn't understand theirs. I hear references to things that real programmers do on a daily basis -- unit testing, code reviews, but I only have the vaguest sense of what these are. I normally don't have many bugs in my little projects, so I have never needed a bug tracking system or tests for them. And the last thing is that it takes me a long time to understand other people's code. Variable naming conventions (that vary with each new language) are difficult (__mzkwpSomRidicAbbrev), and I find the loose coupling difficult. That's not to say I don't loosely couple things -- I think I'm quite good at it for my own work, but when I download something like the Linux kernel or the Chromium source code to look at it, I spend hours trying to figure out how all of these oddly named directories and files connect. It's a programming sin to reinvent the wheel, but I often find it's just quicker to write up the functionality myself than to spend hours dissecting some library. Obviously, people who do this for a living don't have these problems, and I'll need to get to that point myself. Question: What are some steps that I can take to begin "integrating" with everyone else? Thanks!

  • Ubuntu Server and setting up two nic cards

    - by kmalik
    I have ubuntu server on a computer with a wireless and hardwired nic card. The wireless needs to get the internet and pass it to the ubuntu server as well as pass it along to the hardwired nic card to more computers. I am having issues getting the basic set up as I believe the route table is grabbing from the wrong nic card. The router is 192.168.1.0 and the server is set to 192.168.1.11 on the wireless card through DHCP ETH0 (wired nic card) is set up to be 10.10.10.0 and the server is 10.10.10.1) I am not a linux or networking guru but basically I am trying to have internet come from a guest network 192.168.1.0 i believe to give internet to the ubuntu server then the ubuntu server will also A) have the wired nic serve DHCP addresses to other computers via a switch or router (that acts as a switch) via 10.10.10.0 addresses. And I would love if it also passed along internet capabilities as well if possible. Bu really at this point my hope is to at least get the internet working on the server and the DHCP to pass correctly. At the moment the specific issue I am having is getting ubuntu server to connect to the internet and have both nic cards up and running correctly. Any help would be appreciated! The route table is as follows: Destination Gateway GM Flags Metric Iface 0.0.0.0 10.10.10.1 0.0.0.0 UG 100 eth0 10.10.10.0 0.0.0.0 255.255.255.0 U 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 eth0 1992.168.1.0 0.0.0.0 255.255.255.255.0 U 0 eth1 My interfaces is set up as follows: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 10.10.10.1 netmask 255.255.255.0 network 10.10.10.0 broadcast 10.10.10.255 gateway 10.10.10.1 domain-name-servers 192.168.1.0 auto eth1 iface eth1 inet dhcp netmask 255.255.255.0 gateway 192.168.1.0 wpa-driver wext wpa-ssid "ssid_name" wpa-ap-scan 1 wpa-proto wpa wpa-pairwise ccmp wpa-group ccmp wpa-key-mgmt wpa-psk wpa-psk "HASH" My DHCPD.conf (as there is a domain name server on here is as follows): ddns-update-style none default-lease-time 600 max-lease-time 7200 authoritative option domain-name "Kamron's Network" option subnet-mask 255.255.255.0 option broadcast-address 10.10.10.255 option routers 192.168.1.0 option domain-name-server 192.168.1.0 98.223.128.213 ooption subnet 10.10.10.0 netmask 255.255.255.0 { range 10.10.10.10 10.10.10.99 } log-facility local7

  • NVIDIA 550M Drivers

    - by DOOM
    First to say, I am newbie, to the linux world and in situation where i have to get used to using ubuntu. My system is: i7-2630QM 8GB Ram with 750GB HD + NVIDIa 550M (1GB) Since i was facing problems with wubi - "slow Ubuntu", i installed it on a separate partition, of 80GB (10GB Swap, 40GB HOME, 30GB ROOT). The system was running fine, before I started using some "CFD" (Graphics Dependent) application. I needed to use "paraview" a graphics software, to design some engineering stuff. Following the installation problems, i installed something called "messa" on my system. The software works but, now my system is "dead-slow". Even with the computer at an idle state, the laptop, is pretty slow, and with huge annoying fan noise. I was tried running some similar applications with windows, and it turns out that its not a hardware, but has to do with the GPU drivers. Following some forums, I installed the "nvidia-current" and now everything is the same. I know, there are many solutions on this forum for nvidia-driver updates, but as you see, nothings working my way. Please someone, tell me what is that I am doing wrong :( This is the output from my terminal for the command lspci | grep 'intel' 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200/2nd Generation Core Processor Family PCI Express Root Port (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) 00:1c.1 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 2 (rev b5) 00:1c.3 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 (rev b5) 00:1c.4 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 5 (rev b5) 00:1c.5 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 6 (rev b5) 00:1d.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation HM67 Express Chipset Family LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) 03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1030 (rev 34)

  • Ubuntu 13.04 boot into black screen, even after installing nvidia drivers, fail at: "Starting Reload cups, upon starting avahi-daemon..."

    - by Elad92
    I got a new machine with i7 4770k and gefore gtx660. I installed windows and then installed Ubuntu 13.04. In the installation everything went well, after the installation I again boot from the USB and choose try ubuntu, and installed boot-repair because windows automatically boot with no option for ubuntu. After I repaired the boot, I restarted and got into grub, when I chose Ubuntu I got message saying I'm running on low graphics mode and when I pressed ok the screen turned off. I couldn't do anything so I restarted and after reading this post: My computer boots to a black screen, what options do I have to fix it? I got into recovery, selected dpkg and repaired packages. Then I rebooted, and tried to press 'e' and change quiet splash to no splash and nomodeset but unfortunately both of them didn't work, and not the screen didn't get turned off, but I just saw a blank screen. So I rebooted again, entered the recovery, and this time I went to the root shell, and tried to install nvidia drivers from this guide here: http://www.howopensource.com/2012/10/install-nvidia-geforce-driver-in-ubuntu-12-10-12-04-using-ppa/ I rebooted and got the same black screen again (the screen didn't go off, just saw a blank screen). In the grub I see that the kernel is 3.8.0-25. I also checked that the usb files are not corrupted using the check CD from the ubuntu installation screen. I'm really frustrated, I don't know what else can I do. (If someone also knows how can I connect to wifi using the root shell it will be very appreciated, because when I choose the 'enable networking' it again booting me to a black screen. Thanks Edit After digging more, I again boot with nomodeset and saw where is it failing, this is the lines I saw: * Starting Reload cups, upon starting avahi-daemon to make sure remote queues are populated [OK] * Starting Reload cups, upon starting avahi-daemon to make sure remote queues are populated [fail] I searched for it in google and this is the closest result I got: http://ubuntuforums.org/showthread.php?t=2144261 i didn't find any way to solve it in the internet, from what I understand this is a problem with 13.04. If someone knows how to fix it I will be very grateful. Thanks Edit 2 - 23.6.13 As Mitch suggested, I disabled the avahi-daemon, and when I boot in nomodeset I get the following error: What else can be the problem?

  • How to Enable JavaScript file API in IE8 [closed]

    - by saeed
    i have developed a web application in asp.net , there is a page in this project which user should choose a file in picture format (jpeg,jpg,bmp,...) and i want to preview image in the page but i don't want to post file to server i want to handle it in client i have done it with java scripts functions via file API but it only works in IE9 but most of costumers use IE8 the reason is that IE8 doesn't support file API is there any way to make IE8 upgrade or some patches in code behind i mean that check if the browser is IE and not support file API call a function which upgrades IE8 to IE9 automatically. i don't want to ask user to do it in message i want to do it programmatic !! even if it is possible install a special patch that is required for file API because customers thought it is a bug in my application and their computer knowledge is low what am i supposed to do with this? i also use Async File Upload Ajax Control But it post the file to server any way with ajax solution and http handler but java scripts do it all in client browser!!! following script checks the browser supports API or not <script> if (window.File && window.FileReader && window.FileList && window.Blob) document.write("<b>File API supported.</b>"); else document.write('<i>File API not supported by this browser.</i>'); </script> following scripts do the read and Load Image function readfile(e1) { var filename = e1.target.files[0]; var fr = new FileReader(); fr.onload = readerHandler; fr.readAsText(filename); } HTML code: <input type="file" id="getimage"> <fieldset><legend>Your image here</legend> <div id="imgstore"></div> </fieldset> JavaScript code: <script> function imageHandler(e2) { var store = document.getElementById('imgstore'); store.innerHTML='<img src="' + e2.target.result +'">'; } function loadimage(e1) { var filename = e1.target.files[0]; var fr = new FileReader(); fr.onload = imageHandler; fr.readAsDataURL(filename); } window.onload=function() { var x = document.getElementById("filebrowsed"); x.addEventListener('change', readfile, false); var y = document.getElementById("getimage"); y.addEventListener('change', loadimage, false); } </script>

  • Programming Language, Turing Completeness and Turing Machine

    - by Amumu
    A programming language is said to be Turing Completeness if it can successfully simulate a universal TM. Let's take functional programming language for example. In functional programming, function has highest priority over anything. You can pass functions around like any primitives or objects. This is called first class function. In functional programming, your function does not produce side effect i.e. output strings onto screen, change the state of variables outside of its scope. Each function has a copy of its own objects if the objects are passed from the outside, and the copied objects are returned once the function finishes its job. Each function written purely in functional style is completely independent to anything outside of it. Thus, the complexity of the overall system is reduced. This is referred as referential transparency. In functional programming, each function can have its local variables kept its values even after the function exits. This is done by the garbage collector. The value can be reused the next time the function is called again. This is called memoization. A function usually should solve only one thing. It should model only one algorithm to answer a problem. Do you think that a function in a functional language with above properties simulate a Turing Machines? Functions (= algorithms = Turing Machines) are able to be passed around as input and returned as output. TM also accepts and simulate other TMs Memoization models the set of states of a Turing Machine. The memorized variables can be used to determine states of a TM (i.e. which lines to execute, what behavior should it take in a give state ...). Also, you can use memoization to simulate your internal tape storage. In language like C/C++, when a function exits, you lose all of its internal data (unless you store it elsewhere outside of its scope). The set of symbols are the set of all strings in a programming language, which is the higher level and human-readable version of machine code (opcode) Start state is the beginning of the function. However, with memoization, start state can be determined by memoization or if you want, switch/if-else statement in imperative programming language. But then, you can't Final accepting state when the function returns a value, or rejects if an exception happens. Thus, the function (= algorithm = TM) is decidable. Otherwise, it's undecidable. I'm not sure about this. What do you think? Is my thinking true on all of this? The reason I bring function in functional programming because I think it's closer to the idea of TM. What experience with other programming languages do you have which make you feel the idea of TM and the ideas of Computer Science in general? Can you specify how you think?
