• Burning Snow Leopard DMG on Ubuntu

  - by Caitlann Lloyd

  So I have a SL Copy of Mac OS X Snow Leopard.DMG and I am running Ubuntu 12.0.4. I tried burn the DMG to a DVD using CD/DVD Creator however when I try, it comes up with a message saying 'The size of the file is over 2 GiB. Files larger than 2 GiB are not supported by the ISO9660 standard in its first and second versions (the most widespread ones). It is recommended to use the third version of the ISO9660 standard, which is supported by most operating systems, including Linux and all versions of Windows™. However, Mac OS X cannot read images created with version 3 of the ISO9660 standard.' How do I bypass this so my DVD is bootable on my iMac. By the way, I'm running Ubuntu on the iMac and it is my only partition. No other OS Installed

• How to take a screenshot every n second?

  - by Seppo Erviälä

  What software can I use to take screenshots with a set interval? I'd like to take screenshots every 2 second or so. Command-line and GUI are both ok. I'd prefer software that can also resize and compress each screenshot. EDIT: What I realized I really wanted to do was take a screenshot and a picture with webcam at the same time. I ended up doing some python: import threading import os def capture(i): i += 1 threading.Timer(2.0, printit, [i]).start() fill = str(i).zfill(5) os.system("scrot scrot-%s.jpg" % fill) os.system("streamer -o streamer-%s.jpeg -s 320x240 -j 100" % fill) capture(0)

• Upgrading Agent Controllers in Oracle Enterprise Manager Ops Center 12c

  - by S Stelting

  Oracle Enterprise Manager Ops Center 12c recently released an upgrade for Solaris Agent Controllers. In this week's blog post, we'll show you how to upgrade agent controllers. Detailed instructions about upgrading Agent Controllers are available in the product documentation here. This blog post uses an Enterprise Controller which is configured for connected mode operation. If you'd like to apply the agent update in a disconnected installation, additional instructions are available here. Step 1: Download Agent Controller Updates With a connected mode Ops Center installation, you can check for product updates at any time by selecting the Enterprise Controller from the left-hand Administration navigation tab. Select the right-hand Action link “Ops Center Downloads” to open a pop-up dialog displaying any new product updates. In this example, the Enterprise Controller has already been upgraded to the latest version (Update 1, also shown as build version 2076) so only the Agent Controller updates will appear. There are three updates available: one for Solaris 10 X86, one for Solaris 8-10 SPARC, and one for all versions of Solaris 11. Note that the last update in the screen shot is the Solaris 11 update; for details on any of the downloads, place your mouse over the information icon under the details column for a pop-up text region. Select the software to download and click the Next button to display the Ops Center license agreement. Review and click the check box to accept the license agreement, then click the Next button to begin downloading the software. The status screen shows the current download status. If desired, you can perform the downloads as a background job. Simply click the check box, then click the next button to proceed to the summary screen. The summary screen shows the updates to be downloaded as well as the current status. Clicking the Finish button will close the dialog and return to the Browser UI. The download job will continue to run in Ops Center and progress can still be viewed from the jobs menu at the bottom of the browser window. Step 2: Check the Version of Existing Agent Controllers After the download job completes, you can check the availability of agent updates as well as the current versions of your Agent Controllers from the left-hand Assets navigation tab. Select “Operating Systems” from the pull-down tab lets to display only OS assets. Next, select “Solaris” in the left-hand tab to display the Solaris assets. Finally, select the Summary tab in the center display panel to show which versions of agent controllers are installed in your data center. Notice that a few of the OS assets are not displayed in the Agent Controllers tab. Ops Center will not display OS instances which do not have an Agent Controller installation. This includes Enterprise Controllers and Proxy Controllers (unless the agent has been activated on the OS instance) and and OS instances using agentless management. For Agent Controllers which support an update, the version of agent software (in this example, 2083) appears to the right of the currently installed version. Step 3: Upgrade Your Agent Controllers If desired, you can upgrade agent controllers from the previous screen by selecting the desired systems and clicking the upgrade button. Alternatively, you can click the link “Upgrade All Agent Controllers” in the right-hand Actions menu: In either case, a pop-up dialog lets you start the upgrade process. The first screen in the dialog lets you choose the upgrade method: Ops Center provides three ways to upgrade agent controllers: Automatic Upgrade: If Agent Controllers are running on all assets, Ops Center can automatically upgrade the software to the latest version without requiring any login credentials to the system SSH using a single set of credentials: If all assets use the same login credentials, you can apply a single set to all assets for the upgrade process. The log-in credentials are the same ones used for asset discovery and management, which are stored in the Plan Management navigation tab under Credentials. SSH using individual credentials: If assets use different login credentials, you can select a different set for each asset. After selecting the upgrade method, click the Next button to proceed to the summary screen. Click the Finish button to close the pop-up dialog and start the upgrade job for the agent controllers. The upgrade job runs a series of tasks in parallel, and will upgrade all agents which have been selected. Once the job completes, the OS instances in your data center will be upgraded and running the latest version of Agent Controller software.

• Can't boot freshly burned Ubuntu cd

  - by user89004

  So I just burned a Ubuntu 12.04.1 powerpc .iso on a cd for my iMac G5 running Mac OS X 10.4.11 and it won't even recognize the cd. I burned it on my dad's Windows 7 laptop as the process is way easier (just 2 clicks). Mac OS X 10.4.11 gives me an error when it starts and when the CD is in saying "the disk you inserted was not readable by this computer". What's funny is that I burned a Ubuntu Minimal .iso on a CD and it would totally read that and even boot it though it gave me some errors afterwards and I couldn't install. I even tried going into openfirmware and hitting boot cd:,\tbxi but I get the error "Warning sector size mismatch can't OPEN cd:,\tbxi Can't open device or file" Was there something wrong with the .iso I burned? Mac OS X 10.4.11 won't even mount that .iso it tells me that the HFS file system is corrupt or something, but I know the .iso doesn't contain HFS file system. Any help? I downloaded the .iso from http://cdimage.ubuntu.com/releases/precise/release/ubuntu-12.04-desktop-powerpc.iso

• Is it a waste of time to free resources before I exit a process?

  - by Martin

  Let's consider a fictional program that builds a linked list in the heap, and at the end of the program there is a loop that frees all the nodes, and then exits. For this case let's say the linked list is just 500K of memory, and no special space managing is required. Is that a wast of time, because the OS will do that anyway? Will there be a different behavior later? Is that different according to the OS version? I'm mainly interested in UNIX based systems, but any information will be appreciated. I had today my first lesson in OS course and I'm wondering about that now.

• what exactly is system programming?

  - by kentjh

  I have never understood what system programming meant. The usual definition given is "...doing something close to the Os or extending Os features...". Does using Windows API directly rather than some libraries to say do file i/o make it system programming? Was writing Android OS system programming? If I write something that would expose linux kernel through a console like app on Android am I doing system programming? If I am writing software to control a washing machine am I writing system programming? I am a beginner in programming and this is confusing me to no end. Please explain contrasting it with "application programming".

• In dual boot PC, the boot/GRUB menu suddenly disappeared (Ubuntu option is not appearing anymore)

  - by iammilind

  I have been using Ubuntu 13.04 as my primary OS for quite sometime on Sony VAIO laptop with other OS being windows 8 (never use it). Till today, everything was fine. In the evening I had shut down my PC and closed the lid; Typically I do this when the shutting down screen is still on. But probably this time it was fatal. When I again restarted my PC, now no menu is appearing for selecting OS and it directly goes for Windows 8. My question is similar to this thread, but I don't have Ubuntu CD as I had installed using pen drive sometime back. Is there any (genuine or workaround) easier way to get back the GRUB menu back in the place? Note that keyboard shortcuts in Sony VAIO is different, here I have an "Assist" menu as well to get those internal options.

• UI Controls Copyright

  - by user3692481

  I'm developing a cross-platform computer software. It will run on Windows and Mac OS X. For user experience reasons, I want it to have the same graphic on both platforms. I really like the Mac OS UI controls and I'd love to see them on the Windows version too. My question is: is it legal to "copy" UI components? I'm not going to copy icons or reproduce an existing Apple software. I would only "copy" some standard UI components such as Buttons, Progressbars, TreeView, ListView etc. You can see them here: http://i.stack.imgur.com/9YzYQ.png http://i.stack.imgur.com/MWR6B.jpg IMHO, they should not be copyrighted for two reasons: They are implicitly used by any Mac OS software There are a lot of Apps (for Windows and even Web-Apps) that are "inspired by" the Mac graphic. Am I right?

• Force Your Mac to Sort Folders on Top of Files (Windows Style)

  - by Eric Z Goodnight

Here’s how to fix that in under five minutes with a clever hack. You know you’ve had that issue. You’ve dug through your files looking for that one elusive folder, and because it’s jumbled in with all the other stuff, it’s more or less impossible to find. Have no fear, with no downloads or silly plug-in software, you can finally make Mac OS behave like Windows and Linux and list those folders in the proper order.  How To Encrypt Your Cloud-Based Drive with BoxcryptorHTG Explains: Photography with Film-Based CamerasHow to Clean Your Dirty Smartphone (Without Breaking Something)

• Why did visual programming never take off and what future paradigms might change that?

  - by Rego

  As the number of "visual" OS's such as Android, iOS and the promised Windows 8 are becoming more popular, it does not seem to me that we programmers have new ways to code using these new technologies, due to a possible lack in new visual programming languages paradigms. I've seen several discussions about incompatibilities between the current coding development environment, and the new OS approaches from Windows 8, Android and other tablets OS's. I mean, today if we have a new tablet, it's almost a requirement for coding, to have, for instance, an external keyboard (due it seems to me it's very difficult to program using the touch screen), exactly because the coding assistance is not conceived to "write" thousands of lines of code. So, how advanced should be the "new" visual programming languages paradigms? Which characteristics these new paradigms would be required?

• dpkg --set-selections from 11.10 on 12.04LTS

  - by Vixxo

  I have to move a server to a different DC in a different country. The server is currently running 11.10, but the new fresh installed OS will be 12.04. The hardware of both is completely different. In order to install the same packages that the server currently uses, I am thinking of exporting all packages to a list and then run this list on the new machine. I will after that proceed with transferring the configuration files for the LAMP stack. My question is if this will work, or if there will be a problem because of the differences in the versions of the OS? What is the correct way to do it? PS. I have no access to KVM to reload the OS as an image, so this would not be an option.

  iPhone OS 4 bêta 3 et SDK Apple a proposé dernièrement aux développeurs la troisième bêta de l'iPhone OS 4 (firmware et SDK). Cette nouvelle version était vraiment attendue par tous les développeurs, car la version précédente était considérée comme une véritable "catastrophe" au point que certain développeur serait retourné sur la dernière version officielle de l'OS (3.1.3). En effet, la bêta 2 était vraiment instable, lente, avec de gros problèmes dans certaine application principale, comme l'incapacité de prendre des photos, l'impossibilité de recharger son iPhone sans être obligé de redémarrer l'appareil ou encore des problèmes aux réseaux Wifi ou 3G.
