• Booting the liveCD/USB in EFI mode fails on Samsung Tablet XE700T1A

  - by F.L.

  My tablet is Samsung Series 7 Slate (XE700T1A-A02FR (French Language)). It operates an Intel Sandy Bridge architecture. The main issue about this tablet is that it ships with an installed Windows 7 in (U)EFI mode (GPT partition table, etc.), so I'd like to get an EFI dual boot with Ubuntu. But it seems I can't boot on the liveCD in EFI mode. It starts loading (up to initrd), but I then get a blank (black) screen. I've tried the nomodeset kernel option (as well as removing quiet and splash) with no luck. [2012-09-27] I have used the Ubuntu 12.04.1 Desktop ISO (I have read somewhere that it is the only one that can boot in EFI mode). I'd say this has something to do with UEFI since the LiveCD boots in bios mode but not in efi mode. Besides, I am not sure my boot info will help, since I can't boot the LiveCD in EFI mode. As a result I can't install ubuntu in EFI mode. So it would be the boot info from the liveCD boot in bios mode. This happens on a ubuntu-12.04.1-desktop-amd64 iso used on a LiveUSB. Live USB was created by dd'ing the iso onto the full disk device (i.e. /dev/sdx no number) of the Flash drive. I have also tried copying the LiveCD files on a primary GPT partition, but with no luck, I just get the grub shell, no menu, no install option. [2012-09-28] I tried today a flash drive created with Ubuntu's Startup Disk Creator and the alternate 12.04.1 64 bit ISO. I get a grub menu in text mode (which meens it did start in efi mode) with install options / test options. But when I start any of these, I simply get a black screen (no cursor, neither mouse nor text-mode cursor). I tried removing the 'quiet' option and adding nomodeset and acpi=off, but it didn't do any good. So this is the same result as for the LiveCD. [2012-10-01] I have tried with a version of the secure remix version via usb-creator-gtk. The boot on the USB key has the same symptoms. Boot in EFI mode is impossible (I have menu but whatever entry I choose, I get the blank screen problem). The boot in BIOS mode works, I did the install. Then I used boot-repair to try installing grub-efi and get a system that would boot in efi mode. But I can't boot this system, because the EFI firmware doesn't seem to detect that sda contains a valid efi partition. Here is the resulting boot-info Boot info 1253554 [2012-10-01] Today, I have reinstalled the pre-shipped version of windows 7, and then installed ubuntu from a secure-remix iso dumped on USB flash drive vie usb-creator-gtk booted in BIOS mode. When install ended, I said "continue testing" then I used boot-repair to try get the bootloader installed. Now, when I boot the tablet, I get the grub menu, it can chainload windows 7 flawlessly. But when I try to start one of the ubuntu options I get the same old blank screen. Here is the new boot-info: Boot info 1253927 [2012-10-01] I tried installing the 3.3 kernel by chrooting a live usb boot (secure remix again) into the installed system. Same symptoms. I feel the key to this is that the device's efi firmware (which is EFI v2.0) would expose the graphics hardware in a way that prevents the kernel to initialize it, and thus prevents it from booting (the kernel stops all drive access just after the screen turns kind of very dark purple). Here is some info on the UEFI firmware as given by rEFInd: EFI revision: 2.00 Platform: x86_64 (64 bit) Firmware: American Megatrends 4.635 Screen Output: Graphics Output (UEFI), 800x600 [2012-10-08] This week end I tried loading the kernel with elilo. Eventhough I didn't have more luck on booting the kernel, elilo gives more info when loading the kernel. I think the next step is trying to load a kernel with EFI stub directly.

• Oracle Retail Mobile Point-of-Service

  - by David Dorf

  When most people discuss mobile in retail, they immediately go to shopping applications.  While I agree the consumer side of mobile is huge, I believe its also important to arm store associates with mobile tools.  There are around a dozen major roll-outs of mobile POS to chain retailers, and all have been successful.  This does not, however, signal the demise of traditional registers.  Retailers will adopt mobile POS slowly and reduce the number of fixed registers over time, but there's likely to be a combination of both for the foreseeable future.  Even Apple retains at least one fixed register in every store, you just have to know where to look. The business benefits for mobile POS are pretty straightforward: 1. Faster checkout.  Walmart's CFO recently reported that for every second they shave off the average transaction time, they can potentially save $12M a year in labor.  I think its more likely that labor will be redeployed to enhance the customer experience. 2. Smarter associates.  The sales associates on the floor need the same access to information that consumers have, if not more.  They need ready access to product details, reviews, inventory, etc. to meet consumer expectations.  In a recent study, 40% of consumers said a savvy store associate can impact their final product selection more than a website. 3. Lower costs.  Mobile POS hardware (iPod touch + sled) costs about a fifth of fixed registers, not to mention the reclaimed space that can be used for product displays. But almost all Mobile POS solutions can claim those benefits equally.  Where there's differentiation is on the technical side.  Oracle recently announced availability of the Oracle Retail Mobile Point-of-Service, and it has three big technology advantages in the market: 1. Portable. We used a popular open-source component called PhoneGap that abstracts the app from the underlying OS and hardware so that iOS, Android, and other platforms could be supported.  Further, we used Web technologies such as HTML5 and JavaScript, which are commonly known by many programmers, as opposed to ObjectiveC which is more difficult to find.  The screen can adjust to different form-factors and sizes, just like you see with browsers.  In the future when a new, zippy device gets released, retailers will have the option to move to that device more easily than if they used a native app. 2. Flexible.  Our Mobile POS is free with the Oracle Retail Point-of-Service product.  Retailers can use any combination of fixed and mobile registers, and those ratios can change as required.  Perhaps start with 1 mobile and 4 fixed per store, then transition over time to 4 mobile and 1 fixed without any additional software licenses.  Our scalable solution supports lots of combinations. 3. Consistent.  Because our Mobile POS is fully integrated to our traditional POS, the same business logic is reused.  Third-party Mobile POS solutions often handle pricing, promotions, and tax calculations separately leading to possible inconsistencies within the store.  That won't happen with Oracle's solution. For many retailers, Mobile POS can lower costs, increase customer service, and generally enhance a consumer's in-store experience.  Apple led the way, but lots of other retailers are discovering the many benefits of adding mobile capabilities in their stores.  Just be sure to examine both the business and technology benefits so you get the most value from your solution for the longest period of time.

• UPOS RFIDScanner data format

  - by Robert Snyder

  A lot of work that I do currently is based in the OPOS/UPOS world. My company has a device that can read 13.56Mhz tags (RFID), Smart Cards, and Mag Stripe cards. Up until somewhat recently I have only been working with RFID for a very specific scenario. That was to read UltraLight C and Desfire cards. These cards were all setup very specifically so that I could take the data read from those cards and force it into a MSR track2 format. The past couple of weeks, however, I have been working on reading RFID credit cards (since I have a Visa card I've been using mine), and Smart Card credit cards. (The visa card I have has both) In learning how to communicate with SmartCard and reading ISO7816 and EMVCO documents I became a little more familiar with how info is stored. But now I have a question regarding UPOS. The RFID data on my Visa is stored (and read) very similar to how the data is stored and read from the Smart Card on my Visa. Cool. Well in the UPOS spec for SmartCardRW the ReadData method returns a byte array. That's cool, I can just return all that data and then parse it as my heart desires. The RFID though has a LinkedList of Tags. Well this makes sense in terms of my Visa card (reminds me of a question I have in regards to SmartCard, but that is for another question) but what about ULC and Desfire, or for that matter any Mifare card. Pages, Files, Purses don't exactly fit the Tag profile. For instance lets just say I read pages 4-12 on my ULC card. Each page I read is 4 bytes long. Does this mean I have 9 tags in my LinkedList? Is my Tag id the page number? Or then how does that translate to Desfire? I open application 123456 and read file 1 and file 2, Do I have 2 tags? and if so what is my tag id? At least with my Visa I think that I have to use the Tag id (ex 5F24 for my expiration date) and value of {0x15, 0x10, 0x31} Part of me says yes..that makes sense. Another part of me says, "well if that is the case then why doesn't SmartCardRW have Tags?" So that is my question. How do I format my data from those different types of media? or is that the job of my Control Object (the application)? Is so how does it know? The only protocols I have are: // Summary: // Enumerates the available predefined RFID tag protocols the device supports. [Flags] public enum RFIDProtocols { EpcClass0 = 1, RFIDSdt0Plus = 2, EpcClass1 = 4, EpcClass1Gen2 = 8, EpcClass2 = 16, Iso14443A = 4096, Iso14443B = 8192, Iso15693 = 12288, Iso180006B = 16384, Other = 16777216, All = 1073741824, } If I use that well all of my cards that I have are all Iso14443A. I use the ATQA and the SAK to know what type of card I really have. There is no RFID property that lets me specify that. So I'm lost.

• Personal Financial Management – The need for resuscitation

  - by Salil Ravindran

  Until a year or so ago, PFM (Personal Financial Management) was the blue eyed boy of every channel banking head. In an age when bank account portability is still fiction, PFM was expected to incentivise customers to switch banks. It still is, in some emerging economies, but if the state of PFM in matured markets is anything to go by, it is in a state of coma and badly requires resuscitation. Studies conducted around the year show an alarming decline and stagnation in PFM usage in mature markets. A Sept 2012 report by Aite Group – Strategies for PFM Success shows that 72% of users hadn’t used PFM and worse, 58% of them were not kicked about using it. Of the rest who had used it, only half did on a bank site. While there are multiple reasons for this lack of adoption, some are glaringly obvious. While pretty graphs and pie charts are important to provide a visual representation of my income and expense, it is simply not enough to encourage me to return. Static representation of data without any insightful analysis does not help me. Budgeting and Cash Flow is important but when I have an operative account, a couple of savings accounts, a mortgage loan and a couple of credit cards help me with what my affordability is in specific contexts rather than telling me I just busted my budget. Help me with relative importance of each budget category so that I know it is fine to go over budget on books for my daughter as against going over budget on eating out. Budget over runs and spend analysis are post facto and I am informed of my sins only when I return to online banking. That too, only if I decide to come to the PFM area. Fundamentally, PFM should be a part of my banking engagement rather than an analysis tool. It should be contextual so that I can make insight based decisions. So what can be done to resuscitate PFM? Amalgamation with banking activities – In most cases, PFM tools are integrated into online banking pages and they are like chapter 37 of a long story. PFM needs to be a way of banking rather than a tool. Available balances should shift to Spendable Balances. Budget and goal related insights should be integrated with transaction sessions to drive pre-event financial decisions. Personal Financial Guidance - Banks need to think ground level and see if their PFM offering is really helping customers achieve self actualisation. Banks need to recognise that most customers out there are non-proficient about making the best value of their money. Customers return when they know that they are being guided rather than being just informed on their finance. Integrating contextual financial offers and financial planning into PFM is one way ahead. Yet another way is to help customers tag unwanted spending thereby encouraging sound savings habits. Mobile PFM – Most banks have left all those numbers on online banking. With access mostly having moved to devices and the success of apps, moving PFM on to devices will give it a much needed shot in the arm. This is not only about presenting the same wine in a new bottle but also about leveraging the power of the device in pushing real time notifications to make pre-purchase decisions. The pursuit should be to analyse spend, budgets and financial goals real time and push them pre-event on to the device. So next time, I should know that I have over run my eating out budget before walking into that burger joint and not after. Increase participation and collaboration – Peer group experiences and comments are valued above those offered by the bank. Integrating social media into PFM engagement will let customers share and solicit their financial management experiences with their peer group. Peer comparisons help benchmark one’s savings and spending habits with those of the peer group and increases stickiness. While mature markets have gone through this learning in some way over the last one year, banks in maturing digital banking economies increasingly seem to be falling into this trap. Best practices lie in profiling and segmenting customers, being where they are and contextually guiding them to identify and achieve their financial goals. Banks could look at the likes of Simple and Movenbank to draw inpiration from.

• Grub2 : Windows 7 can't boot installing with Ubuntu 10.04 on different hard drive

  - by dellphi

  I use a dual boot with two hard disks and two OS is Ubuntu 10.04 and Windows 7. Windows 7 installed on the first disk, first partition. Grub is installed on a second hard disk MBR, and Ubuntu installed on an extended partition on a second hard drive. When I select Windows 7 on the Grub menu, the HDD lamp lights up briefly and then black screen on the monitor, with the status of the keyboard is still functioning. Until now (with the default boot from first HDD), I have to press F12 to get into the Grub to run Linux on a second HDD. ================ fdisk -l ================================ dellph1@dellph1-desktop:~$ fdisk -l omitting empty partition (5) Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00087dec Device Boot Start End Blocks Id System /dev/sda1 * 1 23104 185582848+ 7 HPFS/NTFS /dev/sda2 23105 121601 791177122 5 Extended /dev/sda5 36107 74408 307660783+ 7 HPFS/NTFS /dev/sda6 74409 100081 206218341 7 HPFS/NTFS /dev/sda7 100082 121601 172859368+ 7 HPFS/NTFS Disk /dev/sdb: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x6d43dfb2 Device Boot Start End Blocks Id System /dev/sdb1 1 10030 80560066 5 Extended /dev/sdb5 * 1 5560 44657601 83 Linux /dev/sdb6 5560 9387 30736384 83 Linux /dev/sdb7 9387 10030 5164032 82 Linux swap / Solaris dellph1@dellph1-desktop:~$ ================= grub.cfg ================== # DO NOT EDIT THIS FILE # It is automatically generated by /usr/sbin/grub-mkconfig using templates from /etc/grub.d and settings from /etc/default/grub # BEGIN /etc/grub.d/00_header if [ -s $prefix/grubenv ]; then load_env fi set default="0" if [ ${prev_saved_entry} ]; then set saved_entry=${prev_saved_entry} save_env saved_entry set prev_saved_entry= save_env prev_saved_entry set boot_once=true fi function savedefault { if [ -z ${boot_once} ]; then saved_entry=${chosen} save_env saved_entry fi } function recordfail { set recordfail=1 if [ -n ${have_grubenv} ]; then if [ -z ${boot_once} ]; then save_env recordfail; fi; fi } insmod ext2 set root='(hd1,5)' search --no-floppy --fs-uuid --set 2f014a3a-35f3-4d05-87aa-34ca677160b7 if loadfont /usr/share/grub/unicode.pf2 ; then set gfxmode=1024x768 insmod gfxterm insmod vbe if terminal_output gfxterm ; then true ; else # For backward compatibility with versions of terminal.mod that don't # understand terminal_output terminal gfxterm fi fi insmod ext2 set root='(hd1,5)' search --no-floppy --fs-uuid --set 2f014a3a-35f3-4d05-87aa-34ca677160b7 set locale_dir=($root)/boot/grub/locale set lang=en insmod gettext if [ ${recordfail} = 1 ]; then set timeout=-1 else set timeout=5 fi END /etc/grub.d/00_header BEGIN /etc/grub.d/05_debian_theme insmod ext2 set root='(hd1,5)' search --no-floppy --fs-uuid --set 2f014a3a-35f3-4d05-87aa-34ca677160b7 insmod jpeg if background_image /usr/share/backgrounds/CurlsbyCandy.jpg ; then set color_normal=white/black set color_highlight=black/light-gray else set menu_color_normal=white/black set menu_color_highlight=black/light-gray fi END /etc/grub.d/05_debian_theme BEGIN /etc/grub.d/10_linux menuentry 'Ubuntu, with Linux 2.6.32-24-generic' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod ext2 set root='(hd1,5)' search --no-floppy --fs-uuid --set 2f014a3a-35f3-4d05-87aa-34ca677160b7 linux /boot/vmlinuz-2.6.32-24-generic root=UUID=2f014a3a-35f3-4d05-87aa-34ca677160b7 ro splash vga=795 quiet splash nomodeset video=uvesafb:mode_option=1280x1024-24,mtrr=3,scroll=ywrap initrd /boot/initrd.img-2.6.32-24-generic } menuentry 'Ubuntu, with Linux 2.6.32-24-generic (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod ext2 set root='(hd1,5)' search --no-floppy --fs-uuid --set 2f014a3a-35f3-4d05-87aa-34ca677160b7 echo 'Loading Linux 2.6.32-24-generic ...' linux /boot/vmlinuz-2.6.32-24-generic root=UUID=2f014a3a-35f3-4d05-87aa-34ca677160b7 ro single splash vga=795 echo 'Loading initial ramdisk ...' initrd /boot/initrd.img-2.6.32-24-generic } END /etc/grub.d/10_linux BEGIN /etc/grub.d/30_os-prober menuentry "Windows 7 (loader) (on /dev/sda1)" { insmod ntfs set root='(hd0,1)' search --no-floppy --fs-uuid --set 5cac2139ac210f58 chainloader +1 } END /etc/grub.d/30_os-prober BEGIN /etc/grub.d/40_multisystem Ajout de MultiSystem MULTISYSTEM MENU menuentry "PLoP Boot Manager" { linux16 /boot/plpbt } menuentry "Smart Boot Manager" { search --set -f /boot/sbootmgr.dsk linux16 /boot/memdisk initrd16 /boot/sbootmgr.dsk } FIN MULTISYSTEM MENU END /etc/grub.d/40_multisystem ================================================ I want to keep the Grub on the second HDD.

• Making it GREAT! Oracle Partners Building Apps Workshop with UX and ADF in UK

  - by ultan o'broin

  Yes, making is what it's all about. This time, Oracle Partners in the UK were making great looking usable apps with the Oracle Applications Development Framework (ADF) and user experience (UX) toolkit. And what an energy-packed and productive event at the Oracle UK, Thames Valley Park, location it was. Partners learned the fundamentals of enterprise applications UX, why it's important, all about visual design, how to wireframe designs, and then how to build their already-proven designs in ADF. There was a whole day on mobile apps, learning about mobile design principles, free mobile UX and ADF resources from Oracle, and then trying it out. The workshop wrapped up with the latest Release 7 simplified UIs, Mobilytics, and other innovations from Oracle, and a live demo of a very neat ADF Mobile Android app built by an Oracle contractor. And, what a fun two days both Grant Ronald of ADF and myself had in running the workshop with such a great audience, too! I particularly enjoyed the wireframing and visual design sessions interaction; and seeing some outstanding work done by partners. Of note from the UK workshop were innovative design features not seen before and made me all the happier that developers were bringing their own ideas from the consumer IT world of mobility, simplicity, and social to the world of work apps in a smart way within an enterprise methodology too.  Partner wireframe exercise. Applying mobile design principles and UX design patterns means you've already productively making great usable apps! Next, over to Oracle ADF Mobile with it! One simple example from the design of a mobile field service app was that participants immediately saw how the UX and device functionality of the super UK-based app Hailo app could influence their designs (the London cabbie influence maybe?), as well as how we all use maps, cameras, barcode scanners and microphones on our phones could be used in work. And, of course, ADF Mobile has the device integration solutions there too! I wonder will U.S. workshops in Silicon Valley see an Uber UX influence (LOL)! That we also had partners experienced with Oracle Forms who could now offer a roadmap from Forms to Simplified UI and Mobile using ADF, and do it through through the cloud, really made this particular workshop go "ZING!" for me. Many thanks to the Oracle PartnerNetwork (OPN) team for organizing this event with us, and to the representatives of the Oracle Partners that showed and participated so well. That's what I love out this outreach. It's a two-way, solid value-add for all. Interested? Why would partners and developers with ADF skills sign up for this workshop? Here's why: Learn to use the Oracle Applications User Experience design patterns as the usability building blocks for applications development in Oracle Application Development Framework. The workshop enables attendees to build modern and visually compelling desktop and mobile applications that look and behave like Oracle Cloud Applications, and that can co-exist with partner integrations, new, or existing applications deployments. Partners learn to offer customers and clients more than just coded functionality; instead they can provide a complete user experience with a roadmap for continued ROI from applications that also creating more business and attracts the kudos and respect from other makers of apps as they're wowed by the results. So, if you're a partner and interested in attending one of these workshops and benefitting from such learning, as well as having a platform to show off some of your own work, stay well tuned to your OPN channels, to this blog, to the VoX blog, and to the @usableapps Twitter account too. Can't wait?

  I recently upgraded Ubuntu 12.04 to 12.10 only to find out that it won't connect to any network, neither wired nor wireless and the graphics is messed up too as in a low screen resolution. For 12.04, my system was running perfectly. I don't know why upgrade messed it up so bad. Reinstalling the OS is an issue because I have set up a lot of development environments that I cannot afford to set it up again. Some of the outputs: lspci -nn | grep 0200 02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.

• iPhone: image in table cell - wrong position & not scaled correctly in iPhone 3.0

  - by Karsten Silz

  Hi, I have a custom table cell in an iPhone 3.x app to show basketball player data, including a picture. Here's my code from the table controller: UIImageView *theImage = (UIImageView *) [cell viewWithTag:0]; theImage.image = [manager getSmallImageForPlayer: data.number]; theImage.frame = CGRectMake(14, 0, 30, 44); theImage.clipsToBounds = YES; theImage.contentMode = UIViewContentModeScaleAspectFit; theImage.autoresizingMask = UIViewAutoresizingFlexibleHeight && UIViewAutoresizingFlexibleWidth; theImage.autoresizesSubviews = YES; Here's what it looks like in the iPhone SDK 3.0 simulator: Here's what it looks like in the iPhone SDK 3.1.3 simulator: So I have two problems: In both versions, the image view starts at position (0,0) in the table cell, even though I set the frame to start at (14,0). In the 3.0 simulator (and 3.0 device), the image is not shrunk down correctly, even though I set the image view content mode to "UIViewContentModeScaleAspectFit". But the same code works fine in the 3.1.3 simulator / device. Who can help me with either of these two problems?

• Context migration in CUDA.NET

  - by Vyacheslav

  I'm currently using CUDA.NET library by GASS. I need to initialize cuda arrays (actually cublas vectors, but it doesn't matters) in one CPU thread and use them in other CPU thread. But CUDA context which holding all initialized arrays and loaded functions, can be attached to only one CPU thread. There is mechanism called context migration API to detach context from one thread and attach it to another. But i don't how to properly use it in CUDA.NET. I tried something like this: class Program { private static float[] vector1, vector2; private static CUDA cuda; private static CUBLAS cublas; private static CUdeviceptr ptr; static void Main(string[] args) { cuda = new CUDA(false); cublas = new CUBLAS(cuda); cuda.Init(); cuda.CreateContext(0); AllocateVectors(); cuda.DetachContext(); CUcontext context = cuda.PopCurrentContext(); GetVectorFromDeviceAsync(context); } private static void AllocateVectors() { vector1 = new float[]{1f, 2f, 3f, 4f, 5f}; ptr = cublas.Allocate(vector1.Length, sizeof (float)); cublas.SetVector(vector1, ptr); vector2 = new float[5]; } private static void GetVectorFromDevice(object objContext) { CUcontext localContext = (CUcontext) objContext; cuda.PushCurrentContext(localContext); cuda.AttachContext(localContext); //change vector somehow vector1[0] = -1; //copy changed vector to device cublas.SetVector(vector1, ptr); cublas.GetVector(ptr, vector2); CUDADriver.cuCtxPopCurrent(ref localContext); } private static void GetVectorFromDeviceAsync(CUcontext cUcontext) { Thread thread = new Thread(GetVectorFromDevice); thread.IsBackground = false; thread.Start(cUcontext); } } But execution fails on attempt to copy changed vector to device because context is not attached? Any ideas how i can get it work?

• Quantis Quantum Random Number Generator (QRNG) - any reviews?

  - by Tim Post

  I am thinking about getting one of these (PCI) to set up an internal entropy pool similar to this service who incidentally brought us fun captcha challenges. Prior to lightening my wallet, I'm hoping to gather feedback from people who may be using this device. As there is no possible 'correct' answer, I am making this CW and tagging it as subjective. I'm undertaking a project to help write Monte Carlo simulations for a non profit that distributes mosquito nets in Malaria stricken areas. The idea is to model areas to determine the best place to distribute mosquito nets. During development, I expect to consume gigs if not more of the RNG output. We really need our own source. Is this device reliable? Does it have to be re-started often? Is its bandwidth really as advertised? It passes all tests, as far as randomness goes (i.e. NIST/DIEHARD). What I don't want is something in deadlock due to some ioctl in disk sleep that does nothing but radiate heat. This is not a spamvertisement, I'm helping out of pocket and I really, really want to know if such a large purchase will bear fruit. I can't afford to build a HRNG based on radioactive decay, this looks like the next best thing. Any comments are appreciated. I will earn zero rep for this, please do not vote to close. This is no different than questions regarding the utilization of some branded GPU for some odd purpose. Answers pointing to other solutions will be gladly accepted, I'm not married to this idea.

• UIKeyBoard resize on orientation change to landscape

  - by Dave

  This is very rookie question. I have a UIToolBar at the bottom which is supposed to animatedly move up and down with key board when the UIKeyBoard is displayed. I got that working with the help of UIKeyBoard Notifications. The view we are talking about has split view enabled. When device orientation is landscape, both the views as columns are shown [hope that makes sense]. When key board is shown, i do this CGSize keyBoardSize = [[notificationInfo objectForKey:UIKeyboardFrameEndUserInfoKey]CGRectValue].size; CGRect toolbarFrame= [BottomToolBar frame]; toolbarFrame.origin.y -= keyBoardSize.height; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.3]; BottomToolBar .frame = viewFrame; [UIView commitAnimations]; when key board is hiiden i do this toolbarFrame.origin.y += keyBoardSize.height; My Problem is when device orientation changes to landscape, when the key board is visible the bottom tool bar is gone. I see it move up quickly. I am not sure how to fix this. Can anyone help please? Also, is there a way to NOT make the key board span across both the views in the split view?

• Bluetooth development on Windows mobile 6 C#

  - by cheesebunz

  Hi everyone, i recently started on a project which is a puzzle slider game. This application will be using the Bluetooth, and i'm working on the mobile,Samsung omnia i900. This is how my application will work. Any user with this Samsung device plays the game and starts sliding the tiles. There is an option to search and connect to other users with the same device and application, so that they can solve the puzzle together. Right now, i'm working on the Bluetooth Part but am still new to the API. I'm using the 32feet.NET inthehandpersonal.net class library while encountering much difficulties. I am able to search for devices by using: private void btnSearch_Click(object sender, EventArgs e) { BluetoothRadio.PrimaryRadio.Mode = RadioMode.Discoverable; BluetoothRadio myRadio = BluetoothRadio.PrimaryRadio; lblSearch.Text = "" + myRadio.LocalAddress.ToString(); bluetoothClient = new BluetoothClient(); Cursor.Current = Cursors.WaitCursor; BluetoothDeviceInfo[] bluetoothDeviceInfo = { }; bluetoothDeviceInfo = bluetoothClient.DiscoverDevices(10); comboBox1.DataSource = bluetoothDeviceInfo; comboBox1.DisplayMember = "DeviceName"; comboBox1.ValueMember = "DeviceAddress"; comboBox1.Focus(); Cursor.Current = Cursors.Default; } Well, to be honest this is a rip off from some sources i found on the internet but i do understand this part. Next i went on to trying to sending a simple "testing.txt" file and i'm stucked at it. I think i will be using something like the OBEX and Obexwebrequest, obexwebresponse, Uri etc. Could anyone explain it in simple terms for me so that i could understand what they are so that i could continue pairing and etc on Bluetooth development. Sorry making it this long, really appreciate if anyone did waste some time reading it :). Hope alanM sees this :) i'm using their bluetooth library.

• File Translator to Export Animated 3D Character from Autodesk Maya as Quake MD2

  - by Andy R

  I'm wondering if anyone knows of a way to export geometry/textures for a rigged, animated character as Quake MD2? I’m developing an app for mobile devices, and I’ve found that MD2 works great for lightweight OpenGL rendering. I have several animated characters, and I’d like to export them as MD2 from Maya. Here are some of the things I have tried: Exporting FBX to 3D Studio Max and using the QTip plugin -- this works, but only if I convert my animation to point cache (pc2) and bring that into Max. When I do that, QTip plugin doesn’t honor the point cache node, and all I get is the model, no animation Exporting OBJ Sequence to Blender, exporting MD2 from there -- I can’t seem to get blender to compile the imported obj sequence into a single animated object Exporting FBX to Milkshape -- the maya rig gets corrupted in the process Bake point cache for animation, export to FBX, import to Milkshape -- again, Milkshape doesn’t honor the geometry cache, so all that appears is a static character. I’m currently writing a plugin for Maya using the blender MD2 export script as reference (but re-writing using the C++ Maya API), but I’m just wondering if anyone has done this before or has any suggestions of how to do this. Also, if anyone has other suggestions for the best format to render a single animated character on an OpenGL ES (Android or iPhone) device, I would be very grateful! I’m open to trying anything to get these animations rendering on device Thanks!

• Debuging CUDA kernels called from .NET code in VS2008, emulation mode

  - by Danny Varod

  CUDA has an option to compile code in emulation mode, which is supported in the .rules file they provide. I have C# .NET 3.5 SP1 code that calls a native dll, using DllImport, the native dll is compiled via VS2008 using nvcc and its function is to transfer memory from and to CUDA and to invoke CUDA kernels. When the CUDA kernels are correct, everything runs fine, but when there is a bug, I can only step in to the code until the title of the kernels and see the parameters they receive. (I enabled debugging native code in the startup-project's debug options.) I have tried compiling with emulation mode, however I get the CUDA error "mixed device execution" when calling the CUDA memcopy host--device. I tried switching the alloc+dealloc+memcopy with their equivalent non-CUDA versions, but then the same error occurs when invoking the kernels. What did I do wrong in my attempt to using the debug-emulation mode? P.S. I tried this on Vista x64 SP1 + VS2008, with the same solution complied in both x86 and x64, neither worked in emulation mode, both worked in non-emulation mode.

• monitoring iphone 3g/wifi bandswitch

  - by user262325

  Hello everyone I hope add the function to monitor iphone used 3g/wifi band switch. I know I can do these in my app, but I wonder if there is way to monitor all band switch usage of iPhone? I noticed that there is an app http://itunes.apple.com/ca/app/download-meter-for-wi-fi-gprs/id327227530?mt=8 It claims: Works with any carrier (iPods are supported too!). Requires no login/password to your carrier's site. Does not require Internet connection to get traffic usage statistics (works even in Airplane mode) because it gets information on traffic from the device, not a carrier; this means it won't cost you anything to view current traffic consumed, even while roaming in a location where traffic is very expensive. Allows the user to adjust consumed traffic for today or the current month to match traffic amounts reported by your carrier. Stats on the screen are updated every second. Measures traffic in real time with up to byte precision. Separates traffic into incoming and outgoing, Wi-Fi traffic and mobile Internet traffic. It looks like it gets the band switch info from carrier site, but they also said it gets info from device. I am really confused. Welcome any comment. Thanks interdev

• Android Activity is displayed after user unlocks the screen

  - by Dave

  Hi, I was wondering if anyone understood how to make your application be displayed when you unlock the screen. I have an application where the user turns on a Bluetooth device, it connects to the phone, and the user should be presented with a UI. Having them hunt for the app or using the notification menu is not a workable option (too much work and not the obvious behavior). The problem is that: When the screen is unlocked: - you can popup the activity from the background service when Bluetooth connects to a device - User is happy because the UI is right there When the screen is locked: - The application gets started but is destroyed - User unlocks the phone and nothing is there but the homescreen One work around would be to disable the keyguard when the application gets woken up but the nuclear option is a pretty bad option. PS: I know the standard Android assumption is that you shouldn't do this. In the normal case this behavior is fine, but in this case I explicitly did something I want the phone to respond without adding more work for the user to do. As per Google's guidelines if you don't like this behavior there can be an option for you to turn this off or you can not use the application.

• iPhone Safari does not auto scale back down on portrait->landscape->portrait

  - by Tom

  Hi, I have a very simple HTML page with this META tag for the iPhone: <meta name="viewport" content="height=device-height,width=device-width,initial-scale=1.0,user-scalable=no" /> When the page loads in portrait mode it looks fine and the width fits the screen. When I rotate the iPhone to landscape mode the web page is auto resized to fit the landscape width. Good, this is what I want. But when I rotate back to landscape, the page is not resized back to fit the portrait width like it was before. It remains in the landscape width. I want the iPhone to set it back to the right width automatically, just like it did for the landscape mode. I don't think this should involve orientation listeners because it is all done automatically and I don't have any special styling for the different modes. Why doesn't the iPhone resize the web page back in portrait mode? How do I fix this? Thanks! Tom.

• How to get virtual com-port number if DBT_DEVNODES_CHANGED event accrues?

  - by Nick Toverovsky

  Hi! Previously I defined com-port number using DBT_DEVICEARRIVAL: procedure TMainForm.WMDEVICECHANGE(var Msg: TWMDeviceChange); var lpdb : PDevBroadcastHdr; lpdbpr: PDevBroadCastPort; S: AnsiString; begin {????????? ?????????} lpdb := PDevBroadcastHdr(Msg.dwData); case Msg.Event of DBT_DEVICEARRIVAL: begin {??????????} if lpdb^.dbch_devicetype = DBT_DEVTYP_PORT {DBT_DEVTYP_DEVICEINTERFACE} then begin lpdbpr:= PDevBroadCastPort(Msg.dwData); S := StrPas(PWideChar(@lpdbpr.dbcp_name)); GetSystemController.Init(S); end; end; DBT_DEVICEREMOVECOMPLETE: begin {????????} if lpdb^.dbch_devicetype = DBT_DEVTYP_PORT then begin lpdbpr:= PDevBroadCastPort(Msg.dwData); S := StrPas(PWideChar(@lpdbpr.dbcp_name)); GetSystemController.ProcessDisconnect(S); end; end; end; end; Unfortunately, the hardware part of a device with which I was working changed and now Msg.Event has value BT_DEVNODES_CHANGED. I've read msdn. It is said that I should use RegisterDeviceNotification to get any additional information. But, if I got it right, it can't be used for serial ports. The DBT_DEVICEARRIVAL and DBT_DEVICEREMOVECOMPLETE events are automatically broadcast to all top-level windows for port devices. Therefore, it is not necessary to call RegisterDeviceNotification for ports, and the function fails if the dbch_devicetype member is DBT_DEVTYP_PORT. So, I am confused. How can I define the com-port of a device, if a get DBT_DEVNODES_CHANGED in WMDEVICECHANGE event?

• XenServer 5.5 local storage problem

I had to physically move the host, so I shut down all machines via console: xe vm-shutdown force=true vm=my-machine-uuis-s After that I shut down the machine itself by issuing: halt After the reboot today the local storage repository is unplugged.

• Knopflerfish packaging

  - by Jens

  Hello, I am at the moment creating a matrix which is showing how far Knopflerfish, Equinox and Felix are OSGi 4.2 compliant. So far I looked at the Knopflerfish documentation (Link 1, Link 2) to get an idea of how much of the Core and Compendium specs are actually implemented. The core specification seems to be fully implemented, although there are some inconsistent statements about the Security Layer and the Declarative Services. What makes me wonder is how much of all the Compendium specs are implemented: Remote Services Log Service Http Service Device Access Configuration Admin Service Metatype Service Preferences Service User Admin Service Wire Admin Service IO Connector Service Initial Provisioning UPnP Device Service Declarative Services Event Admin Service Deployment Admin Auto Configuration Application Admin DMT Admin Service Monitor Admin Service Foreign Application Access Blueprint Container Tracker XML Parser Service Position Measurement and State Execution Environment To find out more I downloaded (Download page) the source code of Knopflerfish and had a look at it. It looks like some parts of the spec are implemented through the "original" framework provided by the OSGi Alliance (org.osgi.*). One example is the UPnP package: Does this mean that missing parts which are not directly implemented by Knopflerfish are added through the "original" OSGi framework? And does this also apply to other frameworks like Felix or Equinox?

• Xcode Link Frameworks "Relative to Current SDK" Doesn't Work When Mixing Mac Framework and iPhone St

  - by bl4th3rsk1t3

  I have a framework of code I maintain. It's got mac and iphone objective-c code. And some of it is shared. I'm not having any problems with code. It's a problem with Xcode. Let's just call my framework "AwesomeKit" for this problem. The first thing I did was create an xcode Framework project called "AwesomeKit". Add source files to it, link against the common mac frameworks: foundation, cocoa, carbon, etc. It compiles fine. Then, add a new "static library" target, let's call it "AwesomeKit-iPhone" and set the base SDK in the build settings to iphone device 3.1.3. The problem comes when I try to add "Existing Frameworks" to the AweseomKit-iPhone target. -First change the current build target to AwesomeKit-iPhone. -Right click on any group and select "Add Existing Frameworks..." -Choose UIKit.framework UIKit will immediately be highlighted red, as if it's missing. It is indeed missing because Xcode uses the "Relative SDK" setting from the "Mac OS 10.6" SDK. When it should be using it relative to the current target's base sdk iphone device 3.1.3. What the heck? Has anyone experienced this? This is really annoying.
