  • Using EC2 instance as main development platform

    - by David
    My problem I am working as a consultant for various companies. Each company provides me with a laptop with their software on and I also have my own, where I have my development environment. I tend to buy a new laptop every second year and find myself spending lots of time configuring and installing software. I also spend a lot of time waiting for my laptop to process things. To solve all these issues, I am now considering using EC2 (running windows instances) as my main development platform and just access this from any PC I happen to be at. I calculated that running the Large instance (cheapest 64-bit) for 8 hours a day for a year costs me 960$ per year, which is acceptable. I imagine that when I approach the workplace each day, I will make a single tap on my phone to fire up the instance, so it is ready when I get to work. I should have different icons on my phone to fire up the various instance types. The same software should of course automatically be loaded on the various hardware (sometimes I would even need their instance with 68.4 GB of memory). Another advantage is that if I am having a specific problem with my instance, I could fire up another instance and have someone look into the problem and update the image. My question: Does anyone have experience with such a setup on EC2? What kind of problems do you foresee?

  • Increase performance of Samsung 830 256GB SSD

    - by Robert Koritnik
    I have a Samsung 830 SSD in my notebook connected to a SATA interface. This is a rather old HP notebook nc8430 which means SATA is SATA I and not II or even III that disk supports. But SATA I still supports speeds up to 150MB/s so I expected at least double values as per image below. CrystalDiskMark shows rather slow performance: I've been using this SSD for over a year now and I would like to know what to do to make it blazingly fast as other reports say it should be? Edit As suggested I'm adding AS SSD screenshot of the test. And Samsung Magician's benchmark which is likely biased...

  • Bundling in visual studio 2012 for web optimization

    - by Jalpesh P. Vadgama
    I have been writing a series of posts about Visual Studio 2012 features. This series describes what are the new features in the Visual Studio 2012. This post will also be part of Visual Studio 2012 feature series. As we know now days web applications or site are providing more and more features and due to that we have include lots of JavaScript and CSS files in our web application.So once we load site then we will have all the JavaScript  js files and CSS files loaded in the browsers and If you have lots of JavaScript files then its consumes lots of time when browser request them. Following images show the same situation over there.   Here you can see total 25 files loaded into the system and it's almost more than 1MB of total size. As we need to have our web application of site very responsive and need to have high performance application/site, this will be a performance bottleneck to our site. In situation like this, the bundling feature of Visual Studio 2012 and ASP.NET 4.5 comes very handy. With the help of this feature we do optimization there and we can increase performance of our application. To enable this feature in Visual Studio 2012 we just made debug=”false” in web.config of our application like following. Now once you enable this feature and run this application in the browser to see your traffic it will have less items like following. As you can see in the above image there are only 8 items. So after enabling bundling it will automatically convert all js and css files into the one request. Isn’t that cool feature? This feature will surely going to have great impact on performance. Hope you like it. Stay tuned for more.. Till then happy programming!!

  • Synergy: avoid single machine loop when client is not connected

    - by petobens
    In order to loop between my screens I have the following section in my synergy.sgc file: section: links Pedro-Acer: right = pedro-lubuntu left = pedro-lubuntu pedro-lubuntu: left = Pedro-Acer right = Pedro-Acer end With those settings When the client disconnects the server screen wraps around itself as seen in the image below. I don't want this behavior. The only reason I set the config file to loop between my screens is because I want to have a single key to switch between them: keystroke(alt+`) = switchInDirection(right) If there is way to have a single key for switching in both directions without having looping screens then that would also solve my problem.

  • Moving while doing loop animation in RPGMaker

    - by AzDesign
    I made a custom class to display character portrait in RPGMaker XP Here is the class : class Poser attr_accessor :images def initialize @images = Sprite.new @images.bitmap = RPG::Cache.picture('Character.png') #100x300 @images.x = 540 #place it on the bottom right corner of the screen @images.y = 180 end end Create an event on the map to create an instance as global variable, tada! image popped out. Ok nice. But Im not satisfied, Now I want it to have bobbing-head animation-like (just like when we breathe, sometimes bob our head up and down) so I added another method : def move(x,y) @images.x += x @images.y += y end def animate(x,y,step,delay) forward = true 2.times { step.times { wait(delay) if forward move(x/step,y/step) else move(-x/step,-y/step) end } wait(delay*3) forward = false } end def wait(time) while time > 0 time -= 1 Graphics.update end end I called the method to run the animation and it works, so far so good, but the problem is, WHILE the portrait goes up and down, I cannot move my character until the animation is finished. So that's it, I'm stuck in the loop block, what I want is to watch the portrait moving up and down while I walk around village, talk to npc, etc. Anyone can solve my problem ? Or better solution ? Thanks in advance

  • FreeDOS reinstallation -- accidental script change

    - by jerry2144
    I'm extremely new to FreeDOS and I got a new HP desktop computer with the FreeDOS operating system. I messed up and accidentally changed its scripts and messed around with it's boot order. Long story short, I'm getting a disk error when I boot up. I believe I need to just reinstall FreeDOS and all should be good, but I want to get someone's opinion with much more experience than my own. Also, if someone could guide me through the installation process using a DVD installer that would be amazing. I have already downloaded the FreeDOS iso image and unzipped it. I don't know what I need to do now though. Should I even have unzipped it?

  • Installing linux mint in one partition

    - by sha404
    So, I have a disk with a MBR setup(image below). I've managed to have 50 GB unallocated space for intalling Linux Mint 14. And I want to keep the current windows OS too(but don't want the Mint inside windows). Now I've seen in some tutorials that Linux Mint needs several partitions for bootloader, swap, & home. I don't like to have so many partitions & maybe MBR stuff won't let me create more than one now. So, is it possible to install Linux Mint in one partition only? If it is really impossible than what's the minimum number? & how can I accomplish that? Thanks in advance.

  • CentOS Live CD Creation issues

    - by Dheeraj
    I am creating my customized CentOS 6.3 Live CD. I am following information given at https://projects.centos.org/trac/livecd/wiki/GetToolset My "livecd-creator" command completes successfully and an ISO image is created. But when I try to boot up my system with this ISO, it goes up to the CentOS blue screen and then the CAPS lock and Scroll Lock LEDs on the keyboard starts flashing. Then from here after, the system takes no input from keyboard and I have to power cycle it and it does the same thing. Could you get me any suggestion why this is causing and possible workaround. Thanks.

  • Can non-IT people handle a wiki?

    - by Andrew Heath
    (I'm hoping that some of you will have encountered this issue before and can offer some insights...) My company is looking to improve their market research data management. Current data management style: "Hey Jimbo, where's that picture of our WhatZit 2.0? "yeah I remember that email about that company from that guy, gimme a few minutes to search my Outlook" "who has the newest copy of the Important Competitor's product catalogue? Mine is from '09." ... "Colleen does, and she's on maternity leave. You'll have to call her to get her workstation password..." Desired data management style: data organized neatly by topic (legal, economic, industrial, competitor) for each topic, multiple media types stored together (company product images, press releases, contact info) but still neatly sorted by type data editing histories communal access (no data silos) I was thinking about setting up a department wiki for all users to access. It seems to satisfy the four criteria above, but I'm a little concerned about how user-friendly (read: decipherable to non-technical people) it is for the more advanced features like image galleries, article formatting, and the like. Has anyone here setup a wiki for non-IT people and had it not catch on fire//become a ghost town//look like Geocities? Bonus question: can you see any obvious drawbacks to my choice of MediaWiki (or any other wiki) for solving this problem? Thank you.

  • Favicon on gmail has changed from the envelope to a black gun. How do i change it back and why did i

    - by Victoria
    I think my gmail account might have been hacked because I've recently noticed a change in the favicon displayed in the url and the tab, when I logged onto my gmail account. It used to be the common red and white envelope and now it's a black gun. Can anyone tell if this is enough to conclude that my account has been hacked or tampered with? I know someone that would be capable and most probably willing to cause problems to my account among other things. This would be my opsessive ex who's best friend is a hacker. Can anyone help? I need to know if someone has reigns to my computer. And how do I change the favicon back to its orginial image? The black gun really bothers me. Thanks everyone!!!

  • How to configure 1080p HDTV as a monitor

    - by Robot
    I've read several posts that almost answer my question, but not quite. I have a Samsung LN32C530 1080p HDTV I'd like to use as a monitor. I was reasonably successful getting the prior 720p model to work ok using SwitchResX, but I think I just got lucky with the parameters (1360x768@60Hz). I tried the expected (1920x1080@60Hz) values and "nearby" ones, with no luck. Older 720p params actually work, but I get the same small real estate as the older model TV. Trying values near 1080p always displays an image that doesn't match the screen size and is very jagged which makes me think interpolation is making things worse. Also, SwitchResX has a bunch of parameters other than H x W ("porch" etc), and I don't know how they all work together. Any help?

  • DDRescue on Windows or another options like DDRescue for Windows

    - by Frank Thornton
    I have a drive with failed sectors ect... I can't image it with Acronis as it hangs. I can't with Knoppiz it hangs. CHKDSK hangs. I want to use DDRescure but I don't have any Linux boxes running at the moment. I could do is in a VM but that seems like it would be slow and problematic? Are there any ways I can data recovery this disk from my Windows machine or is there an ideal way to work with DDRescue on Windows?

  • Uninstall or Disable Dell Wave

    - by Onion-Knight
    The image we put on our company laptops includes the Dell Wave interface for Biometric log in. The Wave UI increases boot time by about 5 minutes (because it loads the fingerprint database(a feature I don't use)), so I'm trying to uninstall it, but with little success. There is no line-item in the Add/Remove Programs menu to formally delete it, nor is there a Service I can stop/remove to disable the Wave UI. I've tried looking online, but all I find instead are hits for Google Wave and virus-removal forums with HyjackThis dumps that include Dell Wave records. Any ideas? Edit: Removal isn't entirely necessary. Disabling the Wave UI is good enough.

  • listing of VM's created before libvirt installation or started by any other VM management tool

    - by Dr. Death
    if my VM's are not created using virt-manager or are created using any other tool, then virsh system list command does not give them in the list of running VM's however they are running perfectly on my KVM server. Is there a way to list these VM's in my system list anyhow? I have VM's managed by GKVM, AQEMU, libvirt etc. also some of the user start their VM's using the qemu command as follows: kvm "image name" -m "memory". this starts the VM and allow them to work perfectly. but I am not able to list all these VM's using the virsh system list command.

  • Port forwarding not working?

    - by rphello101
    I'm trying to set up an Apache Server to be accessed publicly. I'm using a Netgear R4500 router hooked up to a Motorola SB6121 modem. I can access my server on my computer by typing in my IP address. After following the instructions to forward port 80 so I can access the server from other computers, it does not work (see image). I get "This webpage is not available". I am forwarding to the IP address of my computer. Using this Network Port Scanner Tool, it says "80/tcp filtered http", which, as I understand it, means forwarding did not work correctly. In my Apache httpd file, I have: ServerName 192.168.1.13:80 and Listen 192.168.1.13:80 Anyone know what's wrong or have something I can try? click to enlarge

  • Is there such a thing as "closure" with software work?

    - by Bobby Tables
    I burned out last year (after a decade of fulltime programming jobs) and am on a sabbatical now. With all the self-examination I've started to figure out some of the root causes of my burnout, and one of the major ones is basically this: there was never any real closure in any of the work I've ever done. It was always a case of getting into an open-ended support/maintenance grind and going stale. When I first entered the industry, I had this image of programming work being very project-based. And I expected projects to have a start, beginning, and END. And then you move on and start on something totally new and fresh. Basically I never expected that a lot (most) of software work involves supporting and maintaining the same code base for open-ended long periods of time - years and even decades. That, combined with generally having itchy feet makes me think that burnout is inevitable for me, after 2-3 years, in ANY fulltime software job. All this sounds like I probably should have been a contractor instead of a fulltimer. But when I discuss this with people, a lot of them say that even THEN you can't really escape having to go back and maintain/support the stuff you worked on, over and over (eg. Coming back on support contracts, for example). The nature of software work is simply like that. There is no project closure, unlike in many other engineering fields. So my question is - Is there ANY programming work out there which is based on short to mid term projects/stints and then moving on cleanly? And is there any particular industry domain or specialization where this kind of project work is typical?

  • Redirect some URL requests to CloudFront and the rest direct to the normal server?

    - by indiehacker
    Say I have two types of URL requests that must be handled by my REST API: http://query.restapi.com/image.png?apikey=abc123 http://query.restapi.com/2.0/<apiKey>/resource.json?from=umi.us_census00.state_geometry Is it possible to redirect only some URL requests for static images (ie., regex: *.png?.*) to take advantage of CloudFront's caching and have the rest of the requests go directly to the normal EC2 server (or at least take a speedier indirect route to the normal EC2 server?). Perhaps the added request time for the misses to CloudFront is irrelevant to worry about? Or perhaps my situation is not best to use for CloudFront? I understand I will need to make DNS change where the current URL requests having http://query.restapi.com/some.png?apikey=0123 get redirected to http://d1234.cloudfront.net/some.png, but I am hoping there is some way for just redirecting static .png requests to take advantage of CloudFront?

  • How do I install 10.04 on a Vortex86DX embdedded system?

    - by mathematician1975
    I am trying to install Ubuntu on a Netcom NC-499 board that contains a Vortex86DX processor. The processor vendor claims support for Ubuntu 10.04 but I am having problems installing it. I am trying to install to a 8GB compact flash card attached to the board with an IDE connector, using a USB connection CD-Rom drive and a burned ISO image obtained from this link http://old-releases.ubuntu.com/releases/10.04.0/ubuntu-10.04.3-desktop-i386.iso . Installation proceeds up to the point of around 78% but during the stage where the installer informs me that it is "configuring apt", the installer terminates with a popup dialog containing the following "The installer encountered an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again." I have no idea what to do at this point. I am a Linux novice and I do not really know how to investigate the problems with the installation. I have configured the BIOS exactly according to how the vendor specifies and they assure me that this version is fully compatible with their hardware and yet I am unable to get a decent install. I am able to install Ubuntu 8.04 using exactly the same procedure successfully so I am sure there is no problem with my CD-Rom compatibility or the compact flash drive. Any help will be gratefully received.

  • Script errors when run by launchd at startup, but not when run in Terminal

    - by Mechcozmo
    I'm attempting to create a RAM disk that loads the previous contents when the system starts up, and every six hours writes the contents to a disk image. Currently, when you run the script from the terminal ("sudo bash LogToRAM.sh") everything works fine. But when run from launchd during startup, it doesn't work. Here's the lines from the log; the first line just gives some idea as to where in the boot process we are: SecurityAgent[202] Showing Login Window com.mechcozmo.LogToRAM[51] + /Developer/usr/bin/SetFile -a V /Volumes/LogfileRAMdisk com.mechcozmo.LogToRAM[51] ERROR: File Not Found. (-43) on file: /Volumes/LogfileRAMdisk com.mechcozmo.LogToRAM[51] + /usr/sbin/asr -source '/Library/Application Support/LogToRAM/RAMdisk_store.dmg' -target /Volumes/LogfileRAMdisk/ -noverify Here is the script and plist file in question. Note that 'set -vx' is up at the top of the script; it give a lot of information about what is happening in the script. My current theory is that the /Volumes directory does not exist at this stage of the boot process, but that seems unlikely to be honest.

  • RHEL kickstart with external DVDrom drive

    - by AndyM
    HI I've an old Dell poweredge server with an CDROM drive. I've attached a USB DVDROM and USB stick with my ks.cfg on so I can install RHEL from DVD not loads of CDs :-) I can boot from the RHEL media in DVDROM and point the installer to the USB ks.cfg. This works but the ks.cfg script has the cdrom keyword in it. The install then stops and asks for the RHEL media to be in the CDROM drive not the DVDROM. How can I change the ks.cfg so it uses the external DVDROM for the install media not servers builtin cdrom drive ? I know I can go and rebuild my DVD image to include the ks.cfg , but this is an extra step I dont want to do if I have to. Regards Andy

  • What does dd conv=sync,noerror do?

    - by dding
    So what is the case when adding conv=sync,noerror makes a difference when backing up an entire hard disk onto an image file? Is conv=sync,noerror a requirement when doing forensic stuff? If so, why is it the case with reference to linux fedora? Edit: OK, so if I do dd without conv=sync,noerror, and dd encounters read error when reading the block (let's size 100M), does dd just skip 100M block and reads the next block without writing something (dd conv=sync,noerror writes zeros to 100M of output - so what about this case?)? And if is hash of original hard disk and output file different if done without conv=sync,noerror? Or is this only when read error occurred?
