  • Google I/O 2012 - What's Possible with the Google Drive SDK

    Google I/O 2012 - What's Possible with the Google Drive SDK Nicolas Garnier Partners of Google Drive have already implemented a number of extremely compelling applications that use Google Drive for file storage. Implementing on the Google Drive SDK enables developers to distribute the cost of storage, while also removing the pain of reimplementing file management. In this session, we'll take a look at a number of existing Google Drive SDK implementations with popular apps.

  • Boot existing ubuntu installation on uefi, GPT BTRFS

    - by user204720
    I have looked through many of the questions, and haven't found anything that quite satisfies this problem. I have an ssd hard drive that is bootable from my old computer. It is a standard BIOS, however, I built a new computer with Z87 motherboard that is a UEFI. What I'd like to do is boot from this hard drive without wiping out the hard drive. I've tried booting from legacy mode, doesn't seem to work. Part of the multitude of problems is my partitioning scheme, which is GPT. sdx1 is the btrfs system, sdx2 swap, sdx3 is bios_grub. I've tried setting the UEFI/BIOS to boot in legacy mode, I've tried turning my swap partition into a Grub EFI boot, I've tried copying the file system onto a new drive installed on the new system. However, copying the information doesn't keep the filesystem or subvolumes intact. I've also tried boot-repair which is when I overwrote the swap space. I'd really rather not start over on a new install, so any other suggested trees to bark up would be appreciated. For the record, I hate you Microsoft, and ASUS I understand complying with microsoft, but make it optional... I'm really disappointed in that I have to deal with Windows 8 when I have nothing to do with it. Something I think I could try, but would like to hear from more experienced users. Moving the sdx1 (btrfs /@/@home) partion and opening up a 100 MB partition on the beginning sectors and install efi compatible Grub2 installation. Would it work? How to move a partition?

  • Be There: Tinkerforge/NetBeans Platform Integration Course

    - by Geertjan
    Tinkerforge is an electronic construction kit. It exposes a number of API bindings, including, of course, Java. The nice thing also is that Tinkerforge products are open source, both on the hardware and software levels, so that you can take their bases as a starting point for your own modifications. "The TinkerForge system is a set of pre-built electronics boards that are built in such a way that you can stack the boards (known as bricks), attach accessories (known as bricklets), and have your prototype and and running quickly. Unlike systems, such as the Arduino or Launchpad, the TinkerForge has to be attached to a computer and the computer does all of the work. With an easy set of application programming interfaces (APIs) available in C/C++, C#, Java, PHP, and Ruby, the system is easy to interface and program over USB in a snap." (from this useful article) Henning Krüp, who has arranged several NetBeans Platform Certified Training Courses in the past, in the Nordhorn/Lingen area in Germany, had the inspired idea to focus the next course on integration with Tinkerforge. In other words, the whole course will be focused on creating a standalone Java desktop application that leverages the NetBeans Platform to interact with Tinkerforge! Interested in joining the course or setting up something similar yourself? The course organized by Henning will be held from 19 to 21 September, as explained here, together with contact details.  If you'd like to organize a similar course at a location of your choosing, leave a comment at the end of this blog entry and we'll set something up together!

  • What is Peformance Monitor telling me when my page faults / second are high?

    - by David Robison
    I have a Windows 7 x64 computer that is having performance issues. After some investigation, I have discovered that the page faults / second on it, as reported by Performance Monitor, are really high. Everything else seems to be normal. Resource Monitor reports no hard faults and lots of available memory. Is this a potential cause for problems, or is it a red herring? If it is something that could be causing problems, what should I do next to figure out what is causing it? Here is a screen shot of the Performance Monitor. Notice that the average page faults / second is 75,887. On another computer that does not have problems, this number is closer to 3,000. Here is a screen shot of the Resource Monitor, sorted by hard faults / second, which is currently 0 for all processes.

  • Finding underlying cause of Window 7 Account corruption.

    - by Carl Jokl
    I have been having trouble with my Sister's computer which I built. It is running Windows 7 Ultimate x64. The problem is that I have had problems with the accounts becoming corrupted. First problems manifest themselves in the form of Windows saying the profile failed to be loaded properly and a temporary profile. Eventually the account will not allow login at all. An error message along the lines the authentication service failing the login. I have found information about this problem and how to fix it. The problem being that something has corrupted the account profile and backing up and recreating the accounts fixes the problem. I have been able to fix things and get logins working again but over the period of usually about a week it happens again. Bit by bit the accounts corrupt and then it is back to square one. I am frustrated because I don't know what the underlying cause of the problem is i.e. what is causing the accounts to be corrupted in the first place. At the moment I am just treating the symptoms. I was hoping someone who may have more experience with dealing with this problem might be able to help me find the root cause. Some articles suggest that Norton Internet Security is a big culprit of this problem which is installed. I could try uninstalling Norton and see if it helps. The one thing which is different about this computer to any other I have built is that it has a solid state drive. Actually it has both a hard drive and solid state drive. The documents and settings i.e. the Users directory is stored on the hard drive. This was done following an article about moving the user account data onto a separate drive on Windows 7 which I found on the Internet. Moving the User accounts is more of a pain under Windows 7 and this solution involved creating a low level file system link to the folder from the boot drive (Solid State) to the Hard Drive. The idea is that the computer behaves just as if it is accessing the User's folder from the boot drive but actually the data is stored on the hard drive. This may have nothing to do with the cause of the problem but due to the problem being user account corruption it is a possibility I have not been able to rule out. Any help would be appreciated as I would be glad to see the back of this problem.

  • Using PC or Mac keyboard as Bluetooth keyboard for iPad?

    - by Kevin Hakanson
    I would like to use my computer keyboard (USB) as a Bluetooth keyboard for my iPad, while I am using it with my computer. I was hoping their was an "app for that" that I could run on either Mac or Windows. I imagine how it would work: It would have to emulate a Bluetooth keyboard, and be able to pair with the iPad. Then, when you give focus to this app, it transmits keystrokes from your built-in keyboard out over the Bluetooth connection. Seems simple, but I can't seem to find anything definitive on Google. Has anybody done this? I figure this is cheaper that buying a Apple iPad Keyboard Dock or a Apple Wireless Keyboard from the Apple Store. Also, it's one less item on my desk, which gets cluttered enough with one keyboard.

  • "Bootmgr is missing...." Upon reboot [closed]

    - by Gabe
    Possible Duplicate: Install/running ubuntu on extarnal HDD with a windows laptop? Ill take you through the steps I did. Sorry if this question has already been resolved, I'm new to Ubuntu and forums in general. I have 2 internal HDDs in my computer, both with Win7. One HDD is my mothers, the other is mine. I did this because she didn't want my games on her computer, and my PCs motherboard took a crap on me, so I set up a dual boot. I also have an external HDD. This is what I am trying to install Ubuntu 12.04 on. I formatted the drive by right clicking it, then selecting "Format". It is now in NTSF format. I downloaded the Windows installer, ran it, and selected "I:/" (my externl hdd) as the install location. The download and installation ran smoothly, and it gave me the reboot prompt. I selected "Reboot now" and my PC rebooted. I was then interrupted by the "Bootmgr is missing. Press CTRL + ALT + DEL TO REBOOT" message. NOTE: I would like to use my HDD for a FULL Ubuntu installation, not the Live (i think thats what its called). I want all my files and settings from Ubuntu saved to the External drive as if it was my only drive. If you need more information just ask. Any help would be appreciated. Thanks in advance.

  • What types of programming require practical category theory?

    - by Alexander Gruber
    Category theory has applications in theoretical computer science and obviously is central to abstract mathematics. I have heard that it also has direct practical applications in programming and software development. What type of programming is practical category theory necessary for? What do programmers use category theory to accomplish? Please note my use of "necessary" and "require" in this post. I realize that in some sense most programmers will benefit from having experience in different types of theories, but I am looking for direct applications where the usage of category theory is essential, i.e. if you didn't know category theory, you probably couldn't do it. Also, I'd like to clarify that by "what type of programming," I am hoping less for a broad answer like "functional programming," and more for specific applications like "writing bank software" or "making operating systems."

  • Stop a particular key getting captured by rdesktop

    - by user18151
    Hello, I want F12 to be not capture by my rdesktop while in fullscreen, so that I can do whatever stuff I'm doing on my remote Windows computer, but pressing F12 would bring down yakuake, and I can type down my commands, or use vim etc for whatever I'm doing. Is there any possible way to do this? I tried playing with keymaps, but that didn't help. I set F12 to inhibit, but that seems to have stopped sending F12 altogether, rather than let gnome catch it and let yakuake pop up. Would be really grateful for answers. I am ready to do my homework, if someone could please just give me pointers etc. Thanks :). Sidenote: My current arranement stems from my large monitor in lab, and small personal laptop monitor, and the laptop has Windows 7. My lab computer has Linux, on which I do my coding work.

  • ERP/CRM Systems. Desktop Based ? Web based?

    - by Parhs
    Hello guys... I have seen 2-3 ERPs in action. I am wondering what is better. Desktop based application or webbased displayed on a browser. My first expirience was with a web based ERP when i was 14 years old.. It was web based and terribly slow... For most simple task you had to do lots of clicks... no keyboard support ..... Pages took ages to load. Last year i worked for migrating to a newer computer some old terminal based cobol application. The computer that worked till today and still has no problem was from 1993. The user interface ofcourse was textbased.. The speed that guys placed orders was amazing! just typing the name of the customer , then 5-10 keys to add a product to order.... Comparing to this ERP the page for placing orders Link (click sales orders) seems terribly slow to add a product... No keyboard shortcut works to save what you added and generally i believe you need 4 times more time to place an order compared to the text interface... Having to use both mouse and keyboard for this task is BAD and sadistic... So how can tek heck these people ever use a system like that ??? So in the long run desktop application seems the only way... Ofcourse browsers support shortcuts but the way to overide the defaults that browsers uses isnt cross compatible... That is a hudge problem. Finnaly, if we MUST/forced use cloud in near future what about keyboard shortcuts?? I feel confused... I have seen converters of desktop applications to browser applications but are SLOW as hell... The question is what about user friendliness?What kind of application would you use?

  • Connect to bluetooth device from command line

    - by Ilari Kajaste
    Background: I'm using my bluetooth headset as audio output. I managed to get it working by the long list of instructions on BluetoothHeadset community documentation, and I have automated the process of activating the headset as default audio output into a script, thanks to another question. However, since I use the bluetooth headset with both my phone and computer (and the headset doesn't support two input connections) in order for the phone not to "steal" the connection when handset is turned on, I force the headset into a discovery mode when connecting to the computer (phone gets to connect to it automatically). So even though the headset is paired ok and would in "normal" scenario autoconnect, I have to always use the little bluetooth icon in the notification area to actually connect to my device (see screenshot). What I want to avoid: This GUI for connecting to a known and paired bluetooth device: What I want instead: I'd want to make the bluetooth do exactly what the clicking the connect item in the GUI does, only by using command line. I want to use command line so I can make a single keypress shortcut for the action, and would't need to navigate the GUI every time I want to establish a connection to the device. The question: How can I attempt to connect to a specific, known and paired bluetooth device from command line? Further question: How do I tell if the connection was successful or not?

  • Why do computers get slower over time? [closed]

    - by Paperflyer
    Possible Duplicate: Why does hardware get slower with time? You probably know this: A newly bought computer is snappy and responsive and just really fast. Then you use it for a couple of months and slowly but steadily the computer gets slower. Opening programs now takes a long time, accessing files takes longer, everything just takes longer than it used to. If you wipe your hard drive and reinstall, everything is back to its original snappyness, but will deteriorate again. This always happend with any operating system I used. Worst of all Windows XP, but also with Ubuntu Linux, Fedora Linux, OSX 10.5/10.6, Windows Vista... (haven't used Win 7 long enough to confirm this) Do you know the reason for this? Or even, a cure?

  • Limited connection whenever I connect to a Wi-Fi network outside the company

    - by anderZubi
    Whenever I connect my work laptop to a wireless network outside of my company, the connection shows as Limited, and there is no internet access. I have tried several times by disabling/enabling the network adapter, restarting the computer... without success. Sometimes, after a while, without taking any action, it shows fine, and I have internet access. But can pass 2 hours before this happens. My computer is under a domain network, but I don't think that's the problem, because I can successfuly connect other computers belonging to same domain to other networks. I'm running Windows 8 Pro and my network adapter is the following: Qualcomm Atheros AR9285 Wireless Network Adapter Any idea of which is the problem and how to solve it?

  • Bridging a Windows 7 and Ubuntu dual boot inside an OS

    - by matsko
    I have Windows 7 and Ubuntu installed on my local PC. They're both installed on separate partitions on the same machine, and when the computer boots up the user is given the option to choose which one they want to boot use as the OS. This all works fine, but I want to use Windows 7 instead of Ubuntu, I am required to restart the computer and boot up the other OS. Is is possible to use an "inline" tool that will allow to change between both OSs as if they were windows in Windows 7? Which tool would that be? Does anyone know of anything else than Parallels? Also are there any free tools that would do this?. Many Thanks.

  • Is Gmail Being Blocked by my ISP?

    - by james
    I asked this over at superuser but they weren't able to help, so I was hoping the sysadmins here will be able to advise as to what's wrong. Although the issue here is with a PC and not a server it still deals with networking so I hope it's not too irrelevant. The Issue: I have a desktop on which I cannot access Gmail and also youtube sign in (I believe since youtube is owned by google they both use the same sign in system). On other computers that uses the same connection via a wireless router I can access both gmail and youtube sign in just fine. On this computer which doesn't have a wireless card and so I have to connect via Ethernet cable (connected to a USB converter since the Ethernet port doesn't work anymore) I can access all sites and services including things like aol and hotmail. But only when it comes to gmail, do I get complete and utter throttling. I even turned off my AV ad Firewall momentarily and no luck. The gmail log in page starts to load and by mid point it just stays there loading and loading and loading... never ends. I tried everything, I reset the modem and router multiple times. I reinstalled my operating system from a vista to a windows 7 hoping that a complete reinstall would solve the issue, but no luck. And yes, I am going to call my ISP but not to solve this issue, but to cancel them. I want to upgrade to cable from DSL anyway. I didn't mention my ISP because I'm not sure if that is within the rules (if it's okay some one let me know and I will). P.S. All this happened one day, before that gmail was perfectly accessible in this computer. I can't remember anything special happening on that day prior to this. The only thing I can think of is, my ISP or Google itself is blocking this computer based on it's mac address, but I don't know if that's even done. Additional info: PC: Windows 7 Ultimate 32 bit Connection Type: DSL Connecting Medium: Ethernet cable via USB converter EDIT: I should mention I can access gmail and youtube just fine through a IP proxy service.

  • Alt-Escape has different effect on different Win-XP machines

    - by Ram Rachum
    This is really weird. On my desktop computer, I often use Alt-Escape to send the active window to the background. This is really useful for window management. However, when I try pressing Alt-Escape on my new laptop, it does something similar but not identical: It sends the active window back, but not all the way to the background. i.e., instead of giving it the lowest index number, it just decrements its index number, probably by 1. Both computers have the same Windows XP Professional. Why is this? And how can I make my laptop computer send the active window to the background instead?

  • Removed password from Windows 7, now I cannot login using Remote Desktop

    - by Niels Brinch
    I removed the password from the only account on my Windows 7 computer and now I get the following message when I try to log in. "Possible reasons are blank passwords not allowed". I did some research and found out what I should have done (disable the policy to allow blank passwords) but now I'm already logged out and cannot get back in. Does anyone have any suggestions? Update Thanks for all the answers. I actually think the reason I couldn't login with blank password was because I was logging in with Remote Desktop. I had no idea that made a difference, so didn't think it would be relevant to mention. When I went directly on the physical computer, it did not stop me from logging in without a password.

  • Listing the routing table takes long time to complete

    - by Rafal Rawicki
    When I print routes defined on my computer using route, it takes about 5 to 20 seconds to complete. Why does it take so much time? With VPN enabled: $ time sudo route Kernel IP routing table (...) real 0m21.423s user 0m0.000s sys 0m0.012s With no VPN, this is about 5 seconds - still, computer can do a lot in this time. I've repeated my measurements few times, getting very similar results each try. My machine is Ubuntu with 3.0.0 kernel, but as far as I know, route on the other computers works the same way.

  • SNMP keeps crashing

    - by jldugger
    We're using OpsView/Nagios to monitor our servers. We've added the SNMP service to all our servers and deployed the configuration via GPO, but one win2k3 server seems to have a problem; it crashes pretty regularly. The event log carries messages like: Event Type: Error Event Source: Service Control Manager Event Category: None Event ID: 7034 Date: 6/11/2009 Time: 7:11:49 PM User: N/A Computer: HOSTNNAME Description: The SNMP Service service terminated unexpectedly. It has done this 2 time(s). and also Event Type: Error Event Source: Application Error Event Category: (100) Event ID: 1000 Date: 6/11/2009 Time: 7:11:18 PM User: N/A Computer: HOSTNAME Description: Faulting application snmp.exe, version 5.2.3790.3959, faulting module ntdll.dll, version 5.2.3790.3959, fault address 0x000417af. Now, I could probably set it to simply restart on crash in perpetuity, but I think it's better to fix problems like this. Is this a known problem? If not, what should I do to diagnose it?

  • Why does Ubuntu keep trying to connect to a WiFi network while plugged into an ethernet

    - by labarna
    My desk is situated at the edge of the range of a wireless signal which I use occasionally (when away from my desk) and is therefore saved in network manager. At my desk, however, I plug into the ethernet cable. While I'm working the computer is constantly trying to join the wireless network and usually failing this results in two annoying behaviors. 1: In gnome shell the network connect and disconnect notices keep popping up at the bottom of the screen and I have to click them to make them disappear (I assume it's been fixed in the next version of gnome). 2: (the worst!) Occasionally the wifi password dialog will pop up and ask for the password to this network (which is already saved). An additionally annoyance is that in gnome shell I'll get two copies of the dialog that I have to cancel, one is gnome shell themed (no window border etc...) and the other is just normal gnome themed. (Sometimes if I've been away from the computer for a while I will have multiple copies of this dialog up as its been trying to connect for a while resulting in at times 20 dialogs to cancel). Note, all the while I've been happily connected to the ethernet and have full network access. This is incredibly annoying and distracting, why doesn't ubuntu stop trying to connect to wifi if I'm on the ethernet (unless I want to broadcast my own network, but that's different)?
