  • Using one key for Encryption and HMAC

    - by Vladimir
    Hello, I am wondering whether I can use a shared secret key established between two clients as the HMAC key too. I saw that there is a problem when it is used as a CBC-MAC but I haven't found any evidence it is bad practice for HMACs. Thanks, Vladimir

  • Linq-to-sql Compiled Query is caching result from disposed DataContext

    - by Vladimir Kojic
    Compiled query: public static Func<OperationalDataContext, short, Machine> QueryMachineById = CompiledQuery.Compile((OperationalDataContext db, short machineID) => db.Machines.Where(m => m.MachineID == machineID).SingleOrDefault()); It looks like compiled query is caching Machine object and returning the same object even if query is called from new DataContext (I’m disposing DataContext in the service but I’m getting Machine from previous DataContext). I use POCOs and XML mapping. Getting cached object from the same datacontext is ok, but when I call query with new DataContext I don’t want to get object from old datacontext. Is there something that I don’t do right ? Thanks, Vladimir

  • Magento data-install script

    - by Vladimir Kerkhoff
    I'm trying to build a data install script that I use to setup a new webstore. This script creates the categories, pages and static blocks and default settings for the specific shop (we use a multistore setup to host the shops). In our dev/staging setup this scripts runs great and all categories are build without any problem. But on our live system this script fails. After some debugging I found the difference is in the Flat catalog usage on the live systems. The problem with creating the category with the flat tables enabled is in getting the parent path information based on the parentId given: $parentCategory = Mage::getModel('catalog/category')->load($parentId); Without flat categories enabled this gives a correct parentCategory, but with flat categories enabled it gives an empty object. Why is this behaviour with flat categories enabled?

  • OpenVPN on Ubuntu 11.10 - unable to redirect default gateway

    - by Vladimir Kadalashvili
    I'm trying to connect to connect to OpenVPN server from my Ubuntu 11.10 machine. I use the following command to do it (under root user): openvpn --config /home/vladimir/client.ovpn Everything seems to be OK, it connects normally without any warnings and errors, but when I try to browse the internet I see that I still use my own IP address, so VPN connection doesn't work. When I run openvpn command, it displays the following message among others: NOTE: unable to redirect default gateway -- Cannot read current default gateway from system I think it's the cause of this problem, but unfortunately I don't know how to fix it. Below is full output of openvpn command: Sat Jun 9 23:51:36 2012 OpenVPN 2.2.0 x86_64-linux-gnu [SSL] [LZO2] [EPOLL] [PKCS11] [eurephia] [MH] [PF_INET6] [IPv6 payload 20110424-2 (2.2RC2)] built on Jul

  • Ubuntu backlight problem with Nvidia graphics

    - by Vladimir
    I have a laptop mySN QMG6 / Chiligreen Mobilitas NW which is Quanta TW9 barebone with intel i3 and nvidia 335m GT onboard. On ubuntu distros 10.04, 10.10, 11.04 and 11.10 i had problem with changing screen backlight with nouveau and nvidia drivers. FN+F4/F5 buttons did not change my brightness. I tried to edit xorg.conf, adding Option “RegistryDwords” “EnableBrightnessControl=1? Also tried to add some lines to grug acpi_osi="Linux" acpi_backlight=vendor Neither worked for me. Today I installed Ubuntu 12.04 beta2 and... With nouveau driver my FN key works, and changes the brightness (is it a new 3.0.22 linux kernel, or patched nouveau driver, i don't know). This is a big step forward. But, when installing proprietary nvidia driver (295.33) FN button stops working and i can't change brightness. I also tried workaround with xorg and grub with no result. Tried to install acpi from apt - no result. Is there anything left to try? I really need that nvidia driver working with FN keys, as i would like to have a working 3D acceleration. P.S. Does the nouveau driver has 3d acceleration like nvidia drivers??? If there is need to provide some log data, please write what should i print, as i'm a bit new to Ubuntu. P.P.S. Same problems i had with other Linux distros (Mint, Fedora and others) P.P.P.S. Other FN buttons work with both drivers (Mute, VOL UP/DOWN, WiFi on/off, Bluetooth, Sleep, Start/Pause, Stop, Next/Prev song)

  • How can I store spell & items using a std::vector implementation?

    - by Vladimir Marenus
    I'm following along with a book from GameInstitute right now, and it's asking me to: Allow the player to buy and carry healing potions and potions of fireball. You can add an Item array (after you define the item class) to the Player class for storing them, or use a std::vector to store them. I think I would like to use the std::vector implementation, because that seems to confuse me less than making an item class, but I am unsure how to do so. I've heard from many people that vectors are great ways to store dynamic values (such as items, weapons, etc), but I've not seen it used.

  • Upgrading in java web development

    - by Vladimir Ivanov
    I'm a java web developer for nearly 3 years. Always trying to learn more and be better but still I feel that the amount of knowledge is not that good as I want. The knowledge in some places still seems to be non-systematic and don't provide a very strong base to solve the problems as good as I want to do it. The example I have is my senior developer, whose solutions are always more efficient and beautiful. So, the question is rather simple and hard the same time. What is the right way to get my knowlege be more systematic and therefore improve it's quality. I understand that there is no practically good answer for the all java programming, so let's focus on the modern java web or nearly web technologies: JSF 2.0 JPA2 and Hibernate as persistence provider Web services and Java SE as a core. What methodologies or books or learning technics lead to the strong knowledge base within the given knowledge area?

  • Recursion VS memory allocation

    - by Vladimir Kishlaly
    Which approach is most popular in real-world examples: recursion or iteration? For example, simple tree preorder traversal with recursion: void preorderTraversal( Node root ){ if( root == null ) return; root.printValue(); preorderTraversal( root.getLeft() ); preorderTraversal( root.getRight() ); } and with iteration (using stack): Push the root node on the stack While the stack is not empty Pop a node Print its value If right child exists, push the node's right child If left child exists, push the node's left child In the first example we have recursive method calls, but in the second - new ancillary data structure. Complexity is similar in both cases - O(n). So, the main question is memory footprint requirement?

  • Asus Eee PC 1000HE wireless woes

    - by Vladimir Noobokov
    Ever since I have upgraded my Asus Eee PC 1000HE from Lucid 10.04 to Precise 12.04 I have been having issues with my wireless connections. At first I had wireless dropouts: I would be able to start using wireless, but then after a few minutes the wireless would stop working even though I was still connected to the network. Lately things turned worse: while I connect to my wireless network, it just never works. I tried all sorts of solutions on offer here and in other forums but none worked. At best I got the wireless to work up until I rebooted, at which point I would get the same symptoms again: the wireless network is there, but it's not really working. By now I tried so many different "solutions" I don't know where to start describing them; I have also reinstalled 12.04 several times, enough to make me lose faith in Ubuntu. Help here looks like my last resort. For the record, my Asus Eee PC 1000HE is equipped with an Atheros wireless card. I have reinstalled 12.04, ran all the suggested updates, and receive the following response when I type iwconfig in the terminal: lo no wireless extensions. wlan0 IEEE 802.11bgn ESSID:"Arsenal" Mode:Managed Frequency:2.452 GHz Access Point: 00:04:ED:48:67:89 Bit Rate=1 Mb/s Tx-Power=16 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=70/70 Signal level=-29 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:27 Invalid misc:57 Missed beacon:0 eth0 no wireless extensions. Thanks in advance for any help that might be offered.

  • How Do I Search For Struct Items In A Vector? [migrated]

    - by Vladimir Marenus
    I'm attempting to create an inventory system using a vector implementation, but I seem to be having some troubles. I'm running into issues using a struct I made. NOTE: This isn't actually in a game code, this is a separate Solution I am using to test my knowledge of vectors and structs! struct aItem { string itemName; int damage; }; int main() { aItem healingPotion; healingPotion.itemName = "Healing Potion"; healingPotion.damage= 6; aItem fireballPotion; fireballPotion.itemName = "Potion of Fiery Balls"; fireballPotion.damage = -2; vector<aItem> inventory; inventory.push_back(healingPotion); inventory.push_back(healingPotion); inventory.push_back(healingPotion); inventory.push_back(fireballPotion); if(find(inventory.begin(), inventory.end(), fireballPotion) != inventory.end()) { cout << "Found"; } system("PAUSE"); return 0; } The preceeding code gives me the following error: 1c:\program files (x86)\microsoft visual studio 11.0\vc\include\xutility(3186): error C2678: binary '==' : no operator found which takes a left-hand operand of type 'aItem' (or there is no acceptable conversion) There is more to the error, if you need it please let me know. I bet it's something small and silly, but I've been thumping at it for over two hours. Thanks in advance!

  • Kernel panic while loading Mac OS X on VMWare

    - by Vladimir Gritsenko
    I have Mac OS X 10.6.3 and VMWare 7.1. Trying to run the OS X doesn't work - shortly after booting VMWare announces the machine's death with this pop-up message: The CPU has been disabled by the guest operating system. You will need to power off or reset the virtual machine at this point. The console has a more interesting announcement: The real-time clock was not properly initialized on your system! With a dump of the detected CPU speed (~2.9 GHz), FSB (~94 MHz) and bus ratio (31). Somehow, the code that panics is documented in an accidental .diff file here. Apparently, it commits seppuku if the bus ratio is greater than 30. I underclocked my E6500 to a slower speed, but this apparently didn't make any difference. I can think of two possibilities right now: The CPU info being read is constant, and defines the maximum ability of the CPU. In which case it appears I'm screwed. VMWare presents its own CPU info to the machine, which I can perhaps somehow change. If so, how? If these sound completely off, that's because I'm a real newbie in these matters. Here's hoping you guys can show me the light :-)

  • Boot ISO image from GRUB4DOS on EFI machines

    - by Vladimir Tikhomirov
    I failed with loading ISO image (non-distro) from GRUB2 from USB stick, but found the way how I can boot the GRUB4DOS and then load the image from there. However, it doesn't work all the time and the questions is WHY it doesn't? Environment and loading process: We need to have EFI machine, USB stick, booting ISO, GRUB2 and GRUB4DOS. Last 3 on USB stick. Boot: USB - EFI loader - GRUB2 - GRUB4DOS - ISO image Configuration files To boot GRUB4DOS I use this from grub.cfg: menuentry "image.iso" { linux /syslinux/grub.exe --config-file="/menu.lst" } My menu.lst is here: timeout 20 default 0 title image.iso find --set-root --ignore-floppies --ignore-cd //image.iso map --heads=0 --sectors-per-track=0 //image.iso (hd32) map --hook chainloader (hd32) This works perfectly with Legacy machines. However, when I come to GRUB4DOS, I don't see the menu with image.iso, I see only GRUB command line. That means that my menu.lst didn't load. Why is it like this? Background and ideas I have an idea that GRUB4DOS doesn't recognize my USB stick as a device. I tried the command find and got (hd0,0), (hd0,1), (hd0,2), (rd). When I tried to set root to any of these devices I don't see fat file system, how it was with Legacy machines. The root device is (hd0,0), which has ntfs file system which should be partition with Windows. EFI machines support only GRUB2, so I can't boot GRUB4DOS straight away. Please, don't suggest anything like this, because my image doesn't have kernel. You can imagine that you load HDAT2 or Hiren's boot cd, for example. menuentry "Blancco Blancco5.iso" { set isofile="/image.iso" loopback loop $isofile set root=(loop) linux /isolinux/vmlinuz isofile=$isofile splash quiet initrd /isolinux/initrd }

  • How to update all MathType formulas in the MS Word for Mac

    - by Vladimir
    When I open .doc file in Microsoft Office for Mac 2008 and MathType 6 installed I get "U" in all formulas instead of "v". The original file was made in MSWord 2003 for Windows with MathType 6. But when I click and open the formula in MathType 6 and then save it back I get correct formula as it was originally written with "v". I am trying to figure out how to I trigger all formulas to be opened in MathType in batch without clicking on each. Or could it be fixed in another way

  • Disabling Windows Server 2008 firewall

    - by Vladimir Georgiev
    I am very stupid. I applied a windows firewall rule that blocks all tcp connection and thus kicking me out of remote desktop on a dedicated server. I managed to get into recovery via VNC, which is basically a windows xp recovery system. I have access to the physical files of the Windows Server 2008 R2 installation, but I don't know how to disable the firewall so I can reboot from recovery and connect to the W2K8 via remote desktop. Please, help.

  • How can I move the Windows 8 on-screen keyboard?

    - by Vladimir Sinenko
    From the first look, it seems that the onscreen keyboard in Windows 8 cannot be moved from its default position at the bottom of the screen: However, sometimes it obstructs the input field and should be repositioned (see iOS 5's screenshots for examples) So the question is, can it actually move? If it can, how can I do that? If it cannot, is it possible to use the keyboard to fill an input field that is underneath it?
