• Kernel Panic while Installing Ubuntu 12.10 from USB Drive

  - by user100889

  Good evening, I recently looked into installing Ubuntu alongside my Windows. I was able to mount the iso on a USB drive using Universal USB Installer. I verified it with the MD5sum utility and the hash is correct. When installing, I can get to the screen where I choose the boot order, select the USB drive, and then I get to a screen where Ubuntu seems to be 'loading' (purple background with Ubuntu logo and name in the middle). Then, all of a sudden, I get a "Kernel Panic - Not syncing: fatal exception in interrupt" error message. My specs : Intel Core 2 Duo CPU T5850 @ 2.16 GHz / 4 GB of ram / Packard Bell computer from 2007. / Windows 7 Ultimate x64 installed. What should I do now ? Thanks for your help.

• Ubuntu 11.10 USB 3.0 HDD

  - by Chazm

  I have a problem with my external HDD (WD My Book Essential 1TB) working on USB 3.0 port. I'm using dual boot setup with Windows 7 and Ubuntu 11.10, both 64 bit. While I'm running Windows and rebooting back to Windows everything works well. When I'm switchin to ubuntu everything works great as well. But after 1st reboot from ubuntu neither windows nor ubuntu mount the external drive. I have to reboot the device manually. I suspect that the problem is with unmounting the device on shutdown on ubuntu. The case concern only usb 3.0. When i plug the same device into usb 2 port the problem doesn't persist. Does any1 hit the same problem or have a clue what might goin wrong?

• Secondary fallback/failover network on Cisco ASA

  - by tyranitar

  In my network there is a Cisco ASA 55x0 with "inside" interface (network 192.168.79.0/24) and "outside" interface (network 89.x.x.48/29) There is this nat rule: object network NAToutside nat (inside,outside) dynamic interface and the static route route outside 0.0.0.0 0.0.0.0 89.x.x.49 1 and all ACL rules. Now I have another new outside network by another ISP called "outside2", this network is already natted and the Cisco ASA in in the network 192.168.70.0/24. I would use this network as a fallback one. So I set the nat rule: object network NAToutside2 nat (inside,outside2) dynamic interface and the static route with a different metric route outside2 0.0.0.0 0.0.0.0 192.168.70.1 2 Clearly it doesn't work: when I disconnect the outside ethernet cable no workstation can connect to the Internet throught the outside2 network... What do I need more?

• XAMPP Redirecting to XAMPP directory on Internal Network

  - by user302252

  I installed XAMPP on my desktop. I set up vhosts for about 5 sites and they are all working properly from the desktop itself. The problem arises whenever I try to access these vhosts from my laptop. I changed the hosts file on the laptop to redirect the laptop dev.domain.com requests to the desktop, however, when I try to access these sites from my laptop on the local network, I only receive the XAMPP welcome screen. It seems like when trying to access the vhosts on the desktop from the laptop the vhosts file is ignored as all requests are redirected to the xampp directory. What might I need to adjust to ensure access to the vhosts on the desktop from the laptop?

• Neural Network Output Grouping 0.5?

  - by Mike

  I tried to write a Neural Network system, but even running through simple AND/OR/NOR type problems, the outputs seem to group around 0.5 (for a bias of -1) and 0.7 (for a bias of 1). It doesn't look exactly "wrong"... The 1,1 in the AND pattern does seem higher than the rest and the 0,0 in the OR looks lower, but they are still all grouped so it's debatable. I was wondering a) if there's some obvious mistake I've made or b) if there's any advice for debugging Neural Nets... seeing as you can't always track back exactly where an answer came from... Thanks! Mike

• PHP: upload files to network shared folder

  - by Xi

  Hi there: I have a problem uploading file to a network shared folder. I can connect to the folder by using windows authentication in IE. The script is as followed: $target_path = '\\\\server\\images\\'; $target_path = $target_path . basename( $_FILES['uploadedfile']['name']); if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) { echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded"; } else{ echo "There was an error uploading the file, please try again!"; } when i ran it , I got an error message read: Warning: move_uploaded_file(\server\images\pic_firefox.jpg) [function.move-uploaded-file]: failed to open stream: Permission denied in C:\xxxxxxxxx\uploader.php on line 6 I thought that's because windows authentication doesn't work this way. Is there a way I can upload the file by using username/password? Any thoughts would be appreciated.

• What's the best way to Notify network users of outages or maintenance

  - by Dubs

  There are times when one of our applications is down for maintenance and we'd like to let our users know about it before they start flooding our help desk with calls. What's the best way to notify our users of an event on the network? Some users are on our intranet, while others log in from the Web. Is there an application they can install to which we can send notifications messages? I'm interested to hear what others have come up with to address this requirement. Thanks!

• Programatically check whether a drive letter is a shared/network drive

  - by Philip Daubmeier

  Hi SO community! I searched a while but found nothing that helped me. Is there a way to check whether a drive letter stands for a shared drive/network drive or a local disc in python? I guess there is some windows api function that gives me that info, but I cant find it. Perhaps there is even a method already integrated in python? What I am looking for is something with this or similar behaviour: someMagicMethod("C:\") #outputs True 'is a local drive' someMagicMethod("Z:\") #outputs False 'is a shared drive' That would help me as well: someMagicMethod2() #outputs list of shared drive letters Thanks a lot in advance!

• Connect 4 with neural network: evaluation of draft + further steps

  - by user89818

  I would like to build a Connect 4 engine which works using an artificial neural network - just because I'm fascinated by ANNs. I'be created the following draft of the ANN structure. Would it work? And are these connections right (even the cross ones)? Could you help me to draft up an UML class diagram for this ANN? I want to give the board representation to the ANN as its input. And the output should be the move to chose. The learning should later be done using backpropagation and the sigmoid function should be applied. The engine will play against human players. And depending on the result of the game, the weights should be adjusted then.

• Question about Convolutional neural network.

  - by Nhu Phuong

  I readed few book and acticles about Convolutional neural network, it seem I understand the concept but I don't know how to put it up like in image below: from 28x28 normalized pixel INPUT we get 4 feature map 24x24. but how to get them ? size the INPUT image ? or perform image transformation? but what kind of transformation? or cut up the input image to 4 piece 24x24 by 4 corner? I don't understand the process to me it seem they cut up or resize the image to more smaller at each step. please help thanks.

• Neural Network Inputs and Outputs to meaningful values

  - by Micheal

  I'm trying to determine how to transform my "meaningful input" into data for an Artificial Neural Network and how to turn the output into "meaningful output". The way I can always see of doing it is by convering everything to categories with binary values. For example, rather than outputting age, having a 0-1 for <10, a 0-1 for 10 - 19, etc. Same with the inputs, where I might be using for example, hair colour. Is the only way to turn this into input to have Blonde 0-1, Brown 0-1, etc? Am I missing some entire topic of ANNs? Most of the books and similar I read use theoretical examples.

• .NET Neural Network or AI for Future Predictions

  - by Ian

  Hi All. I am looking for some kind of intelligent (I was thinking AI or Neural network) library that I can feed a list of historical data and this will predict the next sequence of outputs. As an example I would like to feed the library the following figures 1,2,3,4,5 and based on this, it should predict the next sequence is 6,7,8,9,10 etc. The inputs will be a lot more complex and contain much more information. This will be used in a C# application. If you have any recommendations or warning that will be great. Thanks

• Why wont Ubuntu recognize Rogers LTE Rocket stick 330U Sierra wireless modem?

  - by rob lawson

  I tried to plug the rocket stick into the USB slot, and Ubuntu does not recognize that there is anything in the drive. I plug in a standard USB thumbdrive and it is recognized right away. Are there any applications to help me open the rogers folders to see the files, and maybe connect to the Internet using said rocket stick 330U? I've been searching for this answer for almost a week now, seems no one knows how to get the net using this piece of technology.

• How should I configure grub for booting linux kernel from a USB hard drive?

  - by skolima

  I have a laptop hard drive in an external enclosure which I use as a large pendrive. For an added twist, I have installed Linux on it, so I can boot any machine with my distribution of choice (e.g. for data recovery or repairing a b0rked system or just using a borrowed laptop without destroying the preinstalled Windows). The problem is that, depending on the hardware configuration, the USB hard drive may be visible under different paths. For grub configuration I just use (hda0,0) as it is relative to the device the grub was launched from. I have UUID entries in /etc/fstab. I also specify rootwait in the kernel parameters so that it waits for the USB subsystem to settle down before trying to mount the device. What should I pass to the kernel as root= ? Currently boot from the pendrive once, check the debug messages to see what /dev/sdX device has been assigned to the USB drive by the kernel, then reboot and edit the grub configuration. I can't change anything on the PC besides enabling Boot from USB hard drive in BIOS and setting it to higher priority than internal hard drives. There are various initrd generating scripts which include support for UUID in root device path, unfortunately the Gentoo native one (genkernel) does not support rootwait and I had no luck trying to use others. The boot process goes like this (it is quite similar in Windows): The BIOS chooses the boot device and loads whatever is its MBR (which happens to be grub stage-1). Grub loads it's configuration and stage-2 files from device it has set as root, using (hd0) for the device it was loaded from by BIOS. Grub loads and starts a kernel (still the same numbering, so I can use (hd0,0) again ). Kernel initializes all built-in devices (rootwait does it's magic now). Kernel mounts the partition it was passed as root (this is a kernel parameter, not grub parameter). init.d starts the userland booting process, including mounting things from /etc/fstab. Part 5 is the one giving me problems.

• Why Both 8GB USB Flash Drives Have Different Integrities?

  - by Boris_yo

  USB 3.0 SuperTalent Express DUO 8GB recently had its partition corrupted and declared itself "write-protected" and I was told in chat by @sidran32 that this usually means that flash drive gone bad due to writing cycles limit being reached. Having this thumbdrive for over a year being used infrequently, I was in doubt and referred to SuperTalent's support. I was given recovery tool which I executed but it failed first time prompting me to reinsert it. After that, I formatted it with Windows 7 integrated format utility since recovery tool offered to do this as well which was successful. The problem as I have noticed is with integrity of SuperTalent: Compare above to SanDisk's Micro Cruzer 8GB: Am I missing something? Both thumbdrives are of 8GB and have same FAT32 file system.

• How can I hot deploy using the glassfish adapter in Eclipse

  - by Greg

  Has anyone gotten the glassfish v3 adapter to work with Eclipse without restarting every time there's a code change? I tried to set this up but the adapter "republishes" every time I change any file, which is very annoying. It takes up to 3 minutes and locks up my machine for a second. I must remember to constantly stop the adapter before making any changes. I'd settle for just disabling this "feature", but even if I uncheck "publish change immediately" this behavior still happens. I'm using the latest version of the glassfish adapter and tried with eclipse 3.5 and the 3.6 milestone builds.... What setup is everyone using if you have glassfish v3 as your server? Is there any way to actually get the hot deploy feature to work correctly?

• How many times can data be read from a USB flash drive?

  - by John

  While I am aware that performing writes on a USB flash drive degrades the life expectancy of the device. I have heard the quantity of writes is anywhere from 100 thousand to 10 million, but I have not heard about number of read operations. Does reading from the device count toward this total? I am interested in writing only once to a flash drive and setting it to read-only. Then reading files from the device a thousand or more times per day, but am wondering if (at say 1,000 reads per day), the flash drive will need to be replaced within 100 days (assuming a 100,000 r/w cycle lifetime)?
