  • Windows - CPU power management APIs

    - by iulianchira
    What APIs are provided by Windows for CPU power management (I'm interested in CPU frequency scaling, setting min and max CPU frequency - similar to what you can do in Control Panel in power plans, but in a programmatic way). I'm also interested in .Net APIs.

  • Ubuntu 12.04 64 bit doesn't work on a win7 with check point full disk encryption

    - by Victor Rodriguez
    I installed Ubuntu 12.04 64 bit with the Wubi installer on a Windows 7 with Check Point Full Disk Encryption. The Wubi Installer runs without any trouble selecting the compatibility mode with WinXP and as Administrator. The problem is that after the installation is complete and the reboot done, when you restart the system, there's no option to start Ubuntu instead of Windows. I recently installed Ubuntu on other Win7 machines without any problem. But those laptops don't have the Check Point Full Disk Encryption. And when you restart the system you have the option to start in Ubuntu. If somebody has resolved this issue please share...!!! Regards! Víctor

  • The Oracle Cash Management Secret Very Few Customers Know About

    - by Theresa Hickman
    Did you know that Oracle Cash Management has a robust positioning feature? I had no idea. I was under the mistaken impression that Oracle Cash Management only did bank statement reconciliations. It seems I am not alone. In fact, many Oracle Financials customers are also not aware of this even though it is delivered for free with the Oracle Financials license. Even better, last week, Oracle released an enhancement to Oracle Cash Management for Release 12 that will greatly help customers with their cash positioning needs. As we all know, credit is tight these days. Companies need better visibility of their cash and other liquidity positions to make better use of their cash resources. Today, many customers are managing their cash positions manually using spreadsheets. We also hear how many of them are maintaining larger than normal balances in numerous bank accounts because they just do not have the visibility, and therefore the comfort they need. Although spreadsheets may work in the short-term, they are not the best way to manage your cash positions for the long-term especially if you have dozens, or even hundreds of bank and brokerage accounts. Also, spreadsheets are a lot more risky because they can be overwritten, deleted, difficult to audit, etc. With the newly enhanced positioning feature in Oracle Cash Management, customers can manage their daily cash positions using an excel-like interface that is very flexible and user-configurable. You can link the worksheet to an unlimited number of bank accounts to automatically retrieve your opening balances, the current/intra-day cash inflows and outflows, as well as your expected cash flows from your Fx, Investment and Debt positions if you have Oracle's Treasury module . Oracle Cash Management also has direct integration with Oracle Receivables, Oracle Payables, and Payroll, which adds to the comprehensive picture of what's happening with your organizations' cash in real-time. Here's a screen shot of what the cash positioning page looks like: View image As you can see, your Treasurers can obtain a holistic view of all cash positions across any number of bank accounts as well as other sources of cash flow movements. Depending on how they manage their accounts, they can also use this feature to initiate or monitor bank account sweeps or transfers between their zero balance accounts (ZBA) or cash pools. The cash position worksheet provide drill down for more detail and the ability to manually enter items directly into the worksheet for even greater flexibility and control. The enhancements to this feature were released last week. The following list the patches for Release 12.0.6 and 12.1.1: For more information, visit the following website. http://launch.oracle.com.

  • SQL Management Studio - Execute current line

    - by mawaldne
    In SQL Server 2008 Management studio, I can hit F5 to execute everything in the current query window. I can also highlight a query, and hit F5 to run that highlighted query. Instead of having to highlight a query, is there a way I can run the single query my cursor is on, or run a query my cursor is on up to a the first ';'?

  • fd partitions gone from 2 discs, md happy with it and resyncs. How to recover ?

    - by d0nd
    Hey gurus, need some help badly with this one. I run a server with a 6Tb md raid5 volume built over 7*1Tb disks.

Can someone help me? I'm really desperate... :x

  • details on USB stick boot disk creation

    - by Deborah Shadovitz
    I am looking at this: http://www.ubuntu.com/download/help/create-a-usb-stick-on-ubuntu I need to create a boot disk to test Ubuntu to make sure it will run on a PC (Compaq Mini CQ10-120LA) I was given. I can create the boot disk off of a Mac (in English) or Windows (but Windows is in Spanish and foreign to me). Questions: 1) What format do I choose for the USB stick? (I wish the instructions stated this.) 2) What is Dash? (Will I know when I run the installer?) 3) Can I do this from a Mac or Windows computer? Or only from Ubuntu?

  • Access secondary hard disk from Virtual Machine

    - by Frank V
    I have a fairly specific question. I had Ubuntu on my Laptop (for years). For a variety of reasons, I've had to switch to Windows but the computer has two hard drives. The main drive was reformatted and I've installed windows. The second hard drive still has the Linux system disk format (not sure on type). Obviously, windows can't access it but can I access it from a Virtual machine (VirtualBox) or will I need to load up a Live-Session to access / move the contents? Edit: If this is possible, how would one proceed to mount the disk?

  • Is there a better way to run ubuntu from usb disk

    - by Adam Butler
    I have an old laptop with a broken hard drive controller and am running the previous ubuntu from a usb. I installed this as per standard instructions by running some program that copied the live cd to the usb. This has had a few problems, it seems like it was just made for trying and not for everyday use. Ideally I would like to do a proper install to the usb disk instead of just running off the installer disk. Is there a way to do this? The main problems I have are: When adding mounts to fstab it gets overwritten on each reboot When installing updates the kernel cannot be updated

  • Looking for fast, minimal, preferrably free disc cloning software [closed]

    - by Dave
    We have to test our application installation and functionality on many Windows operating system versions and languages (XP, Vista, Win7; English, Spanish, Portuguese, etc; 32-bit & b4-bit.) While we can do much of this in virtual machines, we have noticed that VM's sometimes hide problems, or raise false bugs. So, we need to do "bare metal" OS installation for much of our testing. I have been using Acronis True Image for the past year, and am not impressed. It often gives random errors which require a reboot, and is really slow. For example, when trying to restore an image, it goes through a "Locking partition" cycle about three times (once after you click OK on each step of the wizard), each of which can take 5 minutes to complete. This all happens BEFORE it actually starts the image copy, which is sometimes quick (3-5 minutes), sometimes long (hours). The size of all of our images are roughly the same, so that is not related. So, anyway, I'm looking to switch to something else: I only need very basic functionality--just creating images of entire discs, and then restoring those images onto the exact same hard drive at a later date. That's it. I'm not opposed to paying for a good piece of software, but if there is something free out there that does the job well, that would be a preference. My OS on which the imaging software would run is Windows Vista, but a bootable media (into a Linux flavor) would be fine also, as long as its quick to use and reliable. Recommendations? (Also, moderators, if this should be a CW, I'll be happy to mark it as such; unclear about the rules there.)

  • Recovering data from hard disk after an accidental Ubuntu reinstallation

    - by Saurabh Agarwal
    My computer got wiped accidentally due to a fresh Ubuntu installation. Since the drive contains very important data and codes, it would be really great if the same could be recovered. It is a 2TB hard drive which had Ubuntu 10.10 earlier. It now has a Ubuntu 12.04 installed on it (which I understand occupies ~4GB). The machine has been powered off since. The installation was done using a usb with the option where the previous ubuntu installation is removed. Since installation doesn't take a lot of time, I'm inclined to think that the disk wasn't completely formatted and that most of the data is still there. I have no experience with recovery and hence a detailed explanation is very helpful. NOTE: I can arrange an additional 2TB hard disk for copying data. My computer has a fast internet connection and I have other computers connected to the network which I may use to access the previous one as well.

  • Which hard disk drive is which?

    - by djeikyb
    I want to know which hard disk drive corresponds to which device path. It's trivial to match the hard disk stats (brand, size) with the dev path, but I want more. I want to know which drive is which inside my case. What's a good way to go about getting this info? I would prefer not to tear apart my server to remove all the drives, then add back one by one. I am willing to preform reboots. The drives are inconveniently scrunched together in the case. The label information is hidden. I can open the case. Most disks are SATA, so theoretically hot swappable. So, Unplugging and tracing cables might help in answering.
