  • Attempting to dual boot Ubuntu and Windows 7 on Sony Vaio with Insyde H2O BIOS

    - by zach
    My situation is the same that is addressed here Sony VAIO with Insyde H2O EFI bios will not boot into GRUB EFI and here http://www.hackourlife.com/sony-vaio-with-insyde-h2o-efi-bios-ubuntu-12-04-dual-boot I tried to install Ubuntu 12.04 from the Live CD alongside my current Windows 7. I have to switch my BIOS to legacy mode in order to boot from CD. If I were to do a normal installation and remain in legacy mode, the BIOS will display "operating system not found". If I switch back then the BIOS just boots to windows. To solve the problem, I tried following the steps in the previous two articles. My drive is partitioned as: sda1 FAT32 Location of Windows EFI files (flagged as boot in Ubuntu install) sda2 unknown sda3 NFTS Windows C: sda4 ext4 Ubuntu root sda5 swap sda6 ext4 Ubuntu home I was a little confused by the requirement in the second article to "be careful to install Grub bootloader in /dev/sda3" In my case, the relevant partition is sda1. I have tried three things: setting the sda1 mount point as /boot, as /boot/efi, and as the special reserved grub partition. In each install I indicated that grub should be installed in sda1. After each install I reboot to the live CD and look in the sda1. I see EFI/Boot and EFI/Windows, but no EFI/Ubuntu and consequently no grubx64.efi. I understand the recommended procedure of moving grubx64.efi into the EFI/Boot directory and replacing the present bootx64.efi file, but I see no grubx64.efi and I don't know where it should be.

  • Sony VAIO with Insyde H2O EFI bios will not boot into GRUB EFI

    - by Rohan Dhruva
    I bought a new Sony Vaio S series laptop. It uses Insyde H2O BIOS EFI, and trying to install Linux on it is driving me crazy. root@kubuntu:~# parted /dev/sda print Model: ATA Hitachi HTS72756 (scsi) Disk /dev/sda: 640GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 1049kB 274MB 273MB fat32 EFI system partition hidden 2 274MB 20.8GB 20.6GB ntfs Basic data partition hidden, diag 3 20.8GB 21.1GB 273MB fat32 EFI system partition boot 4 21.1GB 21.3GB 134MB Microsoft reserved partition msftres 5 21.3GB 342GB 320GB ntfs Basic data partition 6 342GB 358GB 16.1GB ext4 Basic data partition 7 358GB 374GB 16.1GB ntfs Basic data partition 8 374GB 640GB 266GB ntfs Basic data partition What is surprising is that there are 2 EFI system partitions on the disk. The sda2 partition is a 20gb recovery partition which loads windows with a basic recovery interface. This is accessible by pressing the "ASSIST" button as opposed to the normal power button. I presume that the sda1 EFI System Partition (ESP) loads into this recovery. The sda3 ESP has more fleshed out entries for Microsoft Windows, which actually goes into Windows 7 (as confirmed by bcdedit.exe on Windows). Ubuntu is installed on sda6, and while installation I chose sda3 as my boot partition. The installer correctly created a sda3/EFI/ubuntu/grubx64.efi application. The real problem: for the life of me, I can't set it to be the default! I tried creating a sda3/startup.nsh which called grubx64.efi, but it didn't help -- on rebooting, the system still boots into windows. I tried using efibootmgr, and that shows as it it worked: root@kubuntu:~# efibootmgr BootCurrent: 0000 BootOrder: 0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager root@kubuntu:~# efibootmgr --create --gpt --disk /dev/sda --part 3 --write-signature --label "GRUB2" --loader "\\EFI\\ubuntu\\grubx64.efi" BootCurrent: 0000 BootOrder: 0002,0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager Boot0002* GRUB2 root@kubuntu:~# efibootmgr BootCurrent: 0000 BootOrder: 0002,0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager Boot0002* GRUB2 However, on rebooting, as you guessed, the machine rebooted directly back into Windows.

  • Is there a program that gives the result of a chemical reaction?

    - by Semyon Perepelitsa
    Is there a program where I can type one, two or more components of chemical reaction and find out the result of it? For example, I enter "N2 + H2" and it gives me "N2 + H2 ? NH3". Or "C10H8 + O2" and it shows "C10H8 + O2 ? CO2 + H2O". I don't need coefficient calculator, where I type full reaction and it calculates coefficients (marked bold in next example): C10H8 + 12 O2 = 10 CO2 + 4 H2O.

  • Better filesystem for ZODB and Plone.app.blob

    - by h2o
    I am interested to know which Linux file system is best for hosting Zope's Object Database (Data.fs) and Plone.app.blob (blobstorage). Various reviews from the Internet suggests that XFS is good for hosting both. XFS is fast and works well with large files. Anyone using XFS for Zope or Plone? What optimization flags, if any, do you use for XFS? Note that this is a repost. I originally asked this on StackOverflow and was given a suggestion to post on Severfault instead.

  • For a Chemical Equation Balancer App (Android), how do I count the number of atoms of each element in each term?

    - by Upas
    This is my app: If someone enters "C6H12O6+O2=CO2+H2O", then I have already written code to split the equation into terms, so in an ArrayList called rterms I have the strings: C6H12O6 CO2 and in another ArrayList called pterms, I have: CO2 H2O I need to count the number of C's in each term of the reactants, so 6 for term 1, 0 for term 2, and then the H's and then O's. How would I do this? Any help is appreciated.

  • Why Is it better to use unreadable bytes for client server communication?

    - by Alessa
    I'm composing communication lyrics for client-server and what am I thinking about: "authme username passord" (maybe encrytped) "accept" "get archive of H2O from 03.02.2005 to 20.12.2064" transferring binary structure or "error descrtiption" why I always need to do something like 0x0FA52FD + CRC 0x0D34423 + CRC ... I can see some secure reasons but I think it's not the real reason so why I can't use strings in client-server communication?

  • Create Chemistry Equations and Diagrams in Word

    - by Matthew Guay
    Microsoft Word is a great tool for formatting text, but what if you want to insert a chemistry formula or diagram?  Thanks to a new free add-in for Word, you can now insert high-quality chemistry formulas and diagrams directly from the Ribbon in Word. Microsoft’s new Education Labs has recently released the new Chemistry Add-in for Word 2007 and 2010.  This free download adds support for entering and editing chemistry symbols, diagrams, and formulas using the standard XML based Chemical Markup Language.  You can convert any chemical name, such as benzene, or formula, such as H2O, into a chemical diagram, standard name, or formula.  Whether you’re a professional chemist, just taking chemistry in school, or simply curious about the makeup of Citric Acid, this add-in is an exciting way to bring chemistry to your computer. This add-in works great on Word 2007 and 2010, including the 64 bit version of Word 2010.  Please note that the current version is still in beta, so only run it if you are comfortable running beta products. Getting Started Download the Chemistry add-in from Microsoft Education Labs (link below), and unzip the file.  Then, run the ChemistryAddinforWordBeta2.Setup.msi. It may inform you that you need to install the Visual Studio Tools for Office 3.0.  Simply click Yes to download these tools. This will open the download in your default browser.  Simply click run, or save and then run it when it is downloaded. Now, click next to install the Visual Studio Tools for Office as usual. When this is finished, run the ChemistryAddinforWordBeta2.Setup.msi again.  This time, you can easily install it with the default options. Once it’s finished installing, open Word to try out the Chemistry Add-in.  You will be asked if you want to install this customization, so click Install to enable it. Now you will have a new Chemistry tab in your Word ribbon.  Here’s the ribbon in Word 2010… And here it is in Word 2007.   Using the Chemistry Add-in It’s very easy to insert nice chemistry diagrams and formulas in Word with the Chemistry add-in.  You can quickly insert a premade diagram from the Chemistry Gallery: Or you can insert a formula from file.  Simply click “From File” and choose any Chemical Markup Language (.cml) formatted file to insert the chemical formula. You can also convert any chemical name to it’s chemical form.  Simply select the word, right-click, select “Convert to Chemistry Zone” and then click on its name. Now you can see the chemical form in the sidebar if you click the Chemistry Navigator button, and can choose to insert the diagram into the document.  Some chemicals will automatically convert to the diagram in the document, while others simply link to it in the sidebar.  Either way, you can display exactly what you want. You can also convert a chemical formula directly to it’s chemical diagram.  Here we entered H2O and converted it to Chemistry Zone: This directly converted it to the diagram directly in the document. You can click the Edit button on the top, and from there choose to either edit the 2D model of the chemical, or edit the labels. When you click Edit Labels, you may be asked which form you wish to display.  Here’s the options for potassium permanganate: You can then edit the names and formulas, and add or remove any you wish. If you choose to edit the chemical in 2D, you can even edit the individual atoms and change the chemical you’re diagramming.  This 2D editor has a lot of options, so you can get your chemical diagram to look just like you want. And, if you need any help or want to learn more about the Chemistry add-in and its features, simply click the help button in the Chemistry Ribbon.  This will open a Word document containing examples and explanations which can be helpful in mastering all the features of this add-in. All of this works perfectly, whether you’re running it in Word 2007 or 2010, 32 or 64 bit editions. Conclusion Whether you’re using chemistry formulas everyday or simply want to investigate a chemical makeup occasionally, this is a great way to do it with tools you already have on your computer.  It will also help make homework a bit easier if you’re struggling with it in high school or college.

  • grubx64.efi cannot find grub config or grub files, boots to grub console

    - by endor43
    Sony VAIO with Insyde H2O EFI bios will not boot into GRUB EFI The answer to this question was immensely helpful to me and my new Vaio Z3. The issue that I am having now is that after replacing bootmgfw.efi with grubx64.efi and renaming, it boots directly to grub console. I dont even get a menu where i can chose ubuntu. I tried putting a grub.cfg file next to the new bootmgfw.efi(grubx64.efi), no go? Any ideas how i can get the renamed grubx64.efi to find all the rest of the grub stuff outside of the ESP in my linux parition? Or do i have to move all grub files to /EFI/Microsoft/Boot on ESP? Thank you!

  • How to boot into Live USB/CD with UEFI on latest Vaio S series?

    - by user76528
    I am unable to boot from USB/CD into a live Ubuntu session to proceed with install. Esc or F12 didn't work and I can't seem to be able to enter the bios settings. Sony Vaio S w/ Ivy Bridge (just one month old, Insyde H2O EFI?) I have read about: creating /EFI/boot on a fat16 stick http://ubuntuforums.org/showpost.php?p=12071096&postcount=2 installing rEFInd using the Alternate install CD (supposedly in order not to mess with W7 UEFI boot partition) It's pretty clear what I have to do afterwards http://askubuntu.com/a/157062 but I am at loss on how to simply boot into a Live Session then install. Thank you

  • Netlogo programming question - is it possible to put balanced chemical equations in a model?

    - by user286190
    hi I was wondering if it was possible to put balanced chemical equations, and if possible including state symbols, in the existing netlogo model that i am using, i havenot seen any examples in the models library so was not sure if it was possible. I wanted the model to be able to allow the user to input a balanced chemical equilibrium equation, or the model displays the the equation so then the user can select from them if they do not want to enter their own any help will be greatly appreciated thanks for example ethane + oxygen -- carbon dioxide + steam C2H6 + O2 -- CO2 + H2O

  • Thermal risks to other components when watercooling CPU

    - by B Sharp
    I recently ordered all the components for a new desktop system to replace my old, dying computer. I wanted to have a really quiet desktop, so I got a case rated for being quiet and opted to try a closed-system CPU water cooling kit (Antec Kuhler H2O 620) that was on sale for a very good price over the Thanksgiving weekend. Most of my components are still in transit, but I became somewhat worried when a friend mentioned that abandoning air cooling units can result in heat buildup inside the case due to heat generated by the video card and other components such as RAM, the northbridge, MOSFETs and voltage regulators radiating heat that the CPU fan would normally at least keep circulating around so it doesn't build up in localized areas. Is this a realistic problem? What other precautions should I take to remove heat from other components? Adding more case fans seems like it would get really noisy. Are there quiet alternatives?

  • Can't shutdown Ubuntu (Wubi Installation)

    - by zsgre3nd3s7
    I downloaded Ubuntu 12.04 using Wubi. The installation went correctly and everything was working fine until I tried to shutdown. I clicked shutdown and then Ubuntu started shutdown, but as soon as I saw the Ubuntu logo with blank dots under, it froze. I had to perform a hard shutdown. After booting my computer back and going into Ubuntu, I tried shutting it down again but this time it took me on a black page with lots and lots of log writing on the screen and after a little while, it stopped writing stuff. I was able to input characters using the keyboard and everything, but it never shutdown. I had to perform a hard shutdown again. Now it always gives me a Ubuntu logo and freezes. What should I do? I know hard shutdowns are bad and want to avoid them. Is there anyway to make shutdowns work? I tried a reboot and it also froze on the Ubuntu logo. Sony VAIO Model E SVE17115FDB Laptop. Graphic card - AMD RADEON HD 7650M (and it installed correctly in Ubuntu). BIOS - H2O Bios. Processor - Intel i7-3612QM. Edit: I only installed the AMD/ATI proprietary drivers FGLRX, not the AMD/ATI post release drivers because they keep showing an error message. Here is jockey.log. Edit 2: Here is the log that i mentioned before that appeared on my screen, it appeared after i tried reinstalling my AMD driver but failed so i reinstalled the other one. Sorry for the quality i took those pictures with my phone.

  • Pythonic mapping of an array (Beginner)

    - by scott_karana
    Hey StackOverflow, I've got a question related to a beginner Python snippet I've written to introduce myself to the language. It's an admittedly trivial early effort, but I'm still wondering how I could have written it more elegantly. The program outputs NATO phoenetic readable versions of an argument, such "H2O" - "Hotel 2 Oscar", or (lacking an argument) just outputs the whole alphabet. I mainly use it for calling in MAC addresses and IQNs, but it's useful for other phone support too. Here's the body of the relevant portion of the program: #!/usr/bin/env python import sys nato = { "a": 'Alfa', "b": 'Bravo', "c": 'Charlie', "d": 'Delta', "e": 'Echo', "f": 'Foxtrot', "g": 'Golf', "h": 'Hotel', "i": 'India', "j": 'Juliet', "k": 'Kilo', "l": 'Lima', "m": 'Mike', "n": 'November', "o": 'Oscar', "p": 'Papa', "q": 'Quebec', "r": 'Romeo', "s": 'Sierra', "t": 'Tango', "u": 'Uniform', "v": 'Victor', "w": 'Whiskey', "x": 'Xray', "y": 'Yankee', "z": 'Zulu', } if len(sys.argv) < 2: for n in nato.keys(): print nato[n] else: # if sys.argv[1] == "-i" # TODO for char in sys.argv[1].lower(): if char in nato: print nato[char], else: print char, As I mentioned, I just want to see suggestions for a more elegant way to code this. My first guess was to use a list comprehension along the lines of [nato[x] for x in sys.argv[1].lower() if x in nato], but that doesn't allow me to output any non-alphabetic characters. My next guess was to use map, but I couldn't format any lambdas that didn't suffer from the same corner case. Any suggestions? Maybe something with first-class functions? Messing with Array's guts? This seems like it could almost be a Code Golf question, but I feel like I'm just overthinking :)
